Advanced Practice Nurses' Organization Commitment: Impact of Job Environment, Job Satisfaction, and Person-Organization Fit *

Purpose@#The demand for advanced practice nurses (APNs) has increased globally due to a shortage of physicians and an increased demand for high-quality healthcare. Research is needed on the enhancement of advanced practice nurses' organization commitment. Organization commitment (OC) directly impacts the retention of APNs. This study aims to identify the key factors affecting the OC of advanced practice nurses.MethodA cross-sectional survey was conducted at the largest hospital in South Korea. A total of 189 APNs answered survey questions. A partial least squares-structural equation modeling method was employed to analyze the survey responses. @*Results@#A pay scale of APNs is positively associated with person-organization fit (POF). However, the effect of job location and computer self-efficacy on POF is not significant. Job satisfaction plays a salient direct role in supervision and POF. Job satisfaction is also a significant moderator in the relationship between supervision and POF. POF is significantly associated with both OC and supervision. Supervision has a positive effect on organization commitment. @*Conclusions@#Pay scale, job satisfaction, supervision, and POF are significant factors affecting organization commitment. Establishing an intra-organization entity, such as APN steering committee, to ensure mutual consensus and transparent communication between administrators and APNs would enhance POF, the rating of supervision, and organization commitment.

Schisandrol A and gomisin N from Schisandra chinensis extract improve hypogonadism via anti-oxidative stress in TM3 Leydig cells

BACKGROUND/OBJECTIVES@#Male hypogonadism is a condition where the body does not produce enough testosterone and significantly impacts health. Age, obesity, genetics, and oxidative stress are some physiological factors that may contribute to testosterone deficiency.Previous studies have shown many pharmacological benefits of Schisandra chinensis (S. chinensis) Baillon as an anti-inflammatory and antioxidant. However, the molecular mechanism of attenuating hypogonadism is yet to be well established. This research was undertaken to study the effects of S. chinensis extract (SCE) on testosterone deficiency.MATERIALS/METHODS: S. chinensis fruit was pulverized and extracted using 60% aqueous ethanol. HPLC analysis was performed to analyze and quantify the lignans of the SCE. @*RESULTS@#The 2,2-diphenyl-2-picrylhydrazyl and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) scavenging assays confirmed that the SCE and its major lignans (schisandrol A and gomisin N) inhibit oxidative stress. Effects of SCE analysis on the testosterone level under oxidative stress conditions revealed that both schisandrol A and gomisin N were able to recover the lowered testosterone levels. Through mRNA expression of TM3 Leydig cell, we observed that the SCE lignans were able to induce the enzymes involved in testosterone biosynthesis-related genes such as 3β-HSD4 (P < 0.01 for SCE, and P < 0.001 for schisandrol A and gomisin N), 17β-HSD3 (P < 0.001 for SCE, schisandrol A and gomisin N), and 17, 20-desmolase (P < 0.01 for schisandrol A, and P < 0.001 for SCE and gomisin N). @*CONCLUSIONS@#These results support that SCE and its active components could be potential therapeutic agents for regulating and increasing testosterone production.

Effects of the Advanced Practice Nurse-Led Psychoeducational Program for Colorectal Cancer Survivors

Purpose@#This study aimed to investigate the effects of an advanced practice nurse-led psychoeducational program on distress, anxiety, depression, coping with cancer (CWC), health promotion behavior (HPB), and quality of life (QOL) among colorectal cancer survivors. @*Methods@#This study was designed as a quasi-experimental study with a non-equivalent control group pretest-posttest. The participants were survivors of colorectal cancer who underwent follow-up care. There were 39 survivors: 19 in the experimental group and 20 in the control group. The experimental group performed a psychoeducational program for 120 minutes per session, once a week for a total of six weeks, while the control group received routine education and counseling. Distress, anxiety, depression, CWC, HPB, and QOL were investigated before, immediately after, and 4 weeks after the intervention. The data were analyzed with SPSS/WIN ver. 24.0, using repeated measures ANOVA. @*Results@#There were significant interactions between time and group for distress and anxiety. In addition, CWC interacted with the total of CWC and interpersonal coping, and QOL interacted with the total of QOL and functional status. However, there were no significant differences in the depression or HPB scores. @*Conclusion@#Based on the results of this study, we expect that this program can be used as an effective intervention for colorectal cancer survivors.

Correlation between Dysarthria and Aspiration in Patients with Stroke / 대한연하장애학회지

Objective@#This study examined the correlation between dysarthria and aspiration to determine if dysarthria can predict aspiration in stroke patients. @*Methods@#The medical records of 176 patients with first stroke, who underwent a videofluoroscopic swallowing study (VFSS) and Urimal test of articulation and phonology (U-TAP) at the same time between January 2012 and December 2015 in the authors’ hospital, were reviewed retrospectively. The correlation between the penetration aspiration scale (PAS) score and U-TAP score was analyzed in all patients. The mean PAS score and frequency of each PAS score in the dysarthria group and non-dysarthria group were compared. In addition, the aspiration was analyzed based on the severity of dysarthria in the dysphagia group. All statistical analyses were performed using SPSS software. @*Results@#The correlation between the PAS score and U-TAP score was not statistically significant in all the subjects.The mean PAS score was 3.46±5.52 and 3.07±5.49 in the dysphagia and non-dysphagia group, respectively. The mean PAS score of the dysphagia group was higher than that of the non-dysphagia group. On the other hand, it was not statistically significant. In addition, there was no significant difference in the frequency of the PAS scores between the two groups. The aspiration was compared with the severity of dysarthria according to the U-TAP score; there was no statistically significant difference. @*Conclusion@#No correlation was observed between dysarthria and aspiration in stroke patients. In addition, there was no difference in the frequency of aspiration with or without dysarthria. According to the results of this study, aspiration cannot be predicted by dysarthria in stroke patients. Therefore, each diagnostic test and assessment should be performed for each symptom.

Husserlian Phenomenology in Korean Nursing Research: Analysis, Problems, and Suggestions / 한국간호교육학회지

This paper is a critical review of descriptive phenomenological methodology in Korean nursing research. We propose constructive suggestions for the improvement of descriptive phenomenological methodology in light of Husserl's phenomenological approaches. Methods: Using the key words of 'phenomenology,' 'experience,' and 'nursing,' we identify and analyze 64 Korean empirical phenomenological studies (selected from 282 studies) published in 14 Korean nursing journals from 2005 to 2018. The PubMed and the Korea Citation Index were used to identify the studies. Results: Our analysis shows that all the reviewed articles used Giorgi's or Colaizzi's scientific phenomenological methodology, without critical attention to Husserl's philosophical phenomenological principles. Conclusions: The use of scientific phenomenology in nursing research, which originated in North America, has become a global phenomenon, and Korean phenomenological nursing research has faithfully followed this scholarly trend. This paper argues that greater integration of Husserlian phenomenological principles into scientific phenomenological methodology in nursing research, such as participant-centered bracketing and eidetic reduction, is needed to ensure that scientific phenomenology lives up to its promise as a research methodology.

The Importance of Mandatory COVID-19 Diagnostic Testing Prior to Release from Quarantine

A 14-day quarantine is implemented in many countries in response to the coronavirus disease pandemic. Korea implemented a mandatory quarantine for those who had close contact with infected patients and those returning from abroad. The present study explored the implications of mandatory coronavirus disease 2019 testing before releasing individuals from the 14-day quarantine in Incheon, Korea. From February 11 to July 5, 2020, 19,296 people were self-quarantined, and 56 (0.3%) of them were confirmed cases of COVID-19. Twenty (35.7%) were identified through the reporting of symptoms during quarantine, and 32 (57.1%) were identified using mandatory pre-release RT-PCR tests. Among the 32, 14 (25%) individuals reported mild symptoms and 18 (32.1%) were asymptomatic. It is suggested that mandatory diagnostic testing prior to release and the symptom-based surveillance after the 14-day quarantine may help control delayed or asymptomatic COVID-19 cases.

Key competencies for Korean nurses in prenatal genetic nursing: experiential genetic nursing knowledge, and ethics and law / 보건의료교육평가

Purpose@#This study aims at determining the competencies of Korean nurses in prenatal genetic nursing. @*Methods@#First, a 3-round Delphi survey was conducted to establish prenatal genetic nursing competencies. Second, a prenatal genetic nursing education program (PGNEP), incorporating the findings from the Delphi survey, was designed. Third, a single group pre- and post-quasi-experimental study at a PGNEP workshop was conducted to assess the effectiveness of the integration of the competencies into the PGNEP with the measurements of knowledge about prenatal genetic testing and nursing (K-PGTN) and information needs about prenatal genetic testing and nursing (I-PGTN). Finally, the identified competencies were reexamined for their clarity. @*Results@#Based on the Delphi survey 78 competency components were identified. The components were then classified under 10 categories, which were organized under 4 domains. The domain of “experiential genetic nursing knowledge” and the domain of “ethics and law” were ranked as the first and the second in significance. The quasi-experimental study showed that the mean scores in K-PGTN were significantly increased from 8.19±2.67 to 11.25±2.51 (P<0.001). The mean scores of “ethics and law” in I-PGTN decreased significantly (P=0.023). The headings of 4 categories and 2 domains were revised. @*Conclusion@#This study identified competencies for prenatal genetic nursing and nursing education in Korea. There is a need for nursing instructors and researchers to improve the competencies of nurses in the identified areas. Particular emphasis should be placed on experiential nursing knowledge and on ethics and law related to prenatal genetic nursing.

CD24⁺ Cell Depletion Permits Effective Enrichment of Thymic iNKT Cells While Preserving Their Subset Composition

Invariant NKT (iNKT) cells are a small subset of thymus-generated T cells that produce cytokines to control both innate and adaptive immunity. Because of their very low frequency in the thymus, in-depth characterization of iNKT cells can be facilitated by their enrichment from total thymocytes. Magnetic-activated cell sorting (MACS) of glycolipid antigen-loaded CD1d-tetramer-binding cells is a commonly used method to enrich iNKT cells. Surprisingly, we found that this procedure also dramatically altered the subset composition of enriched iNKT cells. As such, NKT2 lineage cells that express large amounts of the transcription factor promyelocytic leukemia zinc finger were markedly over-represented, while NKT1 lineage cells expressing the transcription factor T-bet were significantly reduced. To overcome this limitation, here, we tested magnetic-activated depletion of CD24⁺ immature thymocytes as an alternative method to enrich iNKT cells. We found that the overall recovery in iNKT cell numbers did not differ between these 2 methods. However, enrichment by CD24⁺ cell depletion preserved the subset composition of iNKT cells in the thymus, and thus permitted accurate and reproducible analysis of thymic iNKT cells in further detail.

Change of the Self-care Agency and Quality of Life after Craniotomy among Patients with Brain tumor according to time

PURPOSE: The purpose of this study was to identify the self-care agency and quality of life (QOL) among patients with brain tumors after craniotomy. METHODS: A sample of 96 patients was recruited from a university hospital in Seoul. Data were collected through a structured questionnaire from August 2017 to December 2018. Data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson correlations and multiple regression analyses with SPSS 24.0, IBM. RESULTS: The mean scores of the 1st and 2nd stages in the self-care agency increased from 4.75 to 5.15, and in the quality of life rose from 67.94 to 78.60. The score of the second stage was higher than the first in all sub-scales of the self-care agency and the quality. Physical function was the only sub-scale of the self-care agency that affected quality of life in both stages (1st: β=.71, p<.001, 2nd : β=.77, p<.001). CONCLUSION: Based on the result, to improve QOL with brain tumor after craniotomy, it is important to assess physical function of patients and provide appropriate interventions.

Effects of Schisandra chinensis fruit extract and gomisin A on the contractility of penile corpus cavernosum smooth muscle: a potential mechanism through the nitric oxide - cyclic guanosine monophosphate pathway

BACKGROUND/OBJECTIVES: This study evaluated the effects and molecular mechanisms of the Schisandra chinensis fruit extract (SC) and its major compound gomisin A (GA), on the contractility of rabbit penile corpus cavernosum smooth muscle (PCCSM). MATERIALS/METHODS: PCCSM was exposed to SC or GA after appropriate pretreatment with nitric oxide synthase (NOS) blocker, guanylate cyclase blocker, adenylyl cyclase blocker or protein kinase A blocker. Subsequently, we evaluated the cyclic nucleotide in the perfusate by radioimmunoassay, protein expression level of neuronal NOS (nNOS) and endothelial NOS (eNOS) by western blot, and the interaction of SC or GA with udenafil and rolipram. RESULTS: Both SC and GA induce PCCSM relaxations in a concentration-dependent manner. Pretreatment with NOS blocker, guanylate cyclase blocker, adenylyl cyclase blocker or protein kinase A blocker result in significantly decreased relaxation. SC and GA also induce the levels of cyclic nucleotide in the perfusate in a concentration-dependent manner. Perfusion with GA also showed significantly higher levels of eNOS protein. Furthermore, the udenafil and rolipram induced relaxations of PCCSM were enhanced after exposure to SC and GA. Our results indicate that SC and GA induce the relaxation of PCCSM via the nitric oxide (NO)-cGMP and cAMP signaling pathways. CONCLUSIONS: The SC and GA are potential alternative treatments for men who want to consume natural products to ameliorate erectile function, or who do not respond to the commercially available medicines.

Knowledge and Information Need for Prenatal Genetic Screening and Diagnosis and Attitude toward Terminating Pregnancy among Pregnant Women in South Korea / 한국간호교육학회지

PURPOSE: This study identifies correlations among information needs and knowledge about prenatal genetic screening and diagnosis (I-PGSD & K-PGSD), and attitude toward terminating pregnancy (ATP) among pregnant women in South Korea. METHODS: A descriptive survey was conducted from January 2013 to April 2014 in South Korea. 222 pregnant women responded to three questionnaires developed by the authors. The questionnaire for I-PGSD consisted of 19 questions; 18 questions for K-PGSD; and 10 questions for ATP. RESULTS: Mean scores were 80.46±11.73 for I-PGSD; 14.86±3.74 for K-PGSD; and 33.71±6.13 for ATP. The ATP score was positively correlated with the I-PGSD and K-PGSD scores, but statistically significant with only I-PGSD (p=.006). I-PGSD scores were higher than average on three genetic syndromes (Down, Patau, and Edwards syndrome), on management after the diagnosis of positive fetal aneuploidy, and on test result interpretation after the amniocentesis and level II fetal ultrasonogram. CONCLUSION: In light of current legal and moral controversy regarding terminating pregnancy and rapidly advancing prenatal genetic testing technology, more prenatal genetic education for nurses and nursing students who teach pregnant women is needed. In addition, more professional counseling services provided by trained nurses are also required.

PI3Kδ contributes to ER stress-associated asthma through ER-redox disturbances: the involvement of the RIDD–RIG-I–NF-κB axis

Hyperactivation of phosphoinositol 3-kinase (PI3K) has been suggested to be a potential mechanism for endoplasmic reticulum (ER) stress-enhanced airway hyperresponsiveness, and PI3K inhibitors have been examined as asthma therapeutics. However, the regulatory mechanism linking PI3K to ER stress and related pathological signals in asthma have not been defined. To elucidate these pathogenic pathways, we investigated the influence of a selective PI3Kδ inhibitor, IC87114, on airway inflammation in an ovalbumin/lipopolysaccharide (OVA/LPS)-induced asthma model. In OVA/LPS-induced asthmatic mice, the activity of PI3K, downstream phosphorylation of AKT and activation of nuclear factor-κB (NF-κB) were all significantly elevated; these effects were reversed by IC87114. IC87114 treatment also reduced the OVA/LPS-induced ER stress response by enhancing the intra-ER oxidative folding status through suppression of protein disulfide isomerase activity, ER-associated reactive oxygen species (ROS) accumulation and NOX4 activity. Furthermore, inositol-requiring enzyme-1α (IRE1α)-dependent degradation (RIDD) of IRE1α was reduced by IC87114, resulting in a decreased release of proinflammatory cytokines from bronchial epithelial cells. These results suggest that PI3Kδ may induce severe airway inflammation and hyperresponsiveness by activating NF-κB signaling through ER-associated ROS and RIDD–RIG-I activation. The PI3Kδ inhibitor IC87114 is a potential therapeutic agent against neutrophil-dominant asthma.

Penile Erection Induced by Scoparone from Artemisia capillaris through the Nitric Oxide-Cyclic Guanosine Monophosphate Signaling Pathway

PURPOSE: The objective of this study was to evaluate the relaxant effect of scoparone from Artemisia capillaris on rabbit penile corpus cavernosum smooth muscle (PCCSM) and to elucidate the mechanism of action of scoparone for the treatment of erectile dysfunction (ED). MATERIALS AND METHODS: PCCSM that had been precontracted with phenylephrine was treated with 3 Artemisia herbs (A. princeps, A. capillaris, and A. iwayomogi) and 3 fractions (n-hexane, ethyl acetate, and n-butanol) with different concentrations (0.1, 0.5, 1.0, and 2.0 mg/mL). Four components (esculetin, scopoletin, capillarisin, and scoparone) isolated from A. capillaris were also evaluated. The PCCSM was preincubated with Nω-nitro-L-arginine methyl ester hydrochloride (L-NAME) and 1H-[1,2,4] oxadiazolo [4,3-a]quinoxalin-1-one (ODQ). Cyclic nucleotides in the perfusate were measured by a radioimmunoassay. The interactions of scoparone with udenafil and rolipram were also evaluated. RESULTS: A. capillaris extract relaxed PCCSM in a concentration-dependent manner. Scoparone had the highest relaxant effect on PCCSM among the 4 components (esculetin, scopoletin, capillarisin, and scoparone) isolated from the ethyl acetate fraction. The application of scoparone on PCCSM pretreated with L-NAME and ODQ led to significantly less relaxation. Scoparone also increased the cyclic guanosine monophosphate (cGMP) levels in the perfusate in a concentration-dependent manner. Furthermore, scoparone enhanced udenafil- and rolipram-induced relaxation of the PCCSM. CONCLUSIONS: Scoparone relaxed the PCCSM mainly by activating the nitric oxide-cGMP signaling pathway, and it may be a new promising treatment for ED patients who do not completely respond to udenafil.

Quercetin Relaxed the Smooth Muscle of Rabbit Penile Corpus Cavernosum by Activating the NO-cGMP Signaling Pathway

The aim of this study was to investigate the effect and action mechanism of quercetin on penile corpus cavernosum smooth muscle (PCCSM). PCCSM precontracted with phenylephrine (Phe) was treated with four different concentrations of quercetin (10−7, 10−6, 10−5 and 10−4 M). PCCSM were preincubated with N-Nitro-L-arginine methyl ester hydrochloride (L-NAME) and 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) to block nitric oxide synthase and guanylate cyclase, respectively. The changes in PCCSM tension were recorded, and cyclic nucleotides in the perfusate were measured by radioimmunoassay. The interactions of quercetin with phosphodiesterase type 5 inhibitors (PDE5-Is) such as sildenafil, udenafil and mirodenafil, were also evaluated. PCCSM relaxation induced by quercetin occurred in a concentrationdependent manner. The application of quercetin to PCCSM pre-treated with L-NAME and ODQ significantly inhibited the relaxation. Quercetin significantly increased cGMP in the perfusate. Furthermore, quercetin enhanced PDE5-Is-induced relaxation of PCCSM. Quercetin relaxed the PCCSM by activating the NO-cGMP signaling pathway, and it may be a therapeutic candidate or an alternative treatment for patients with erectile dysfunction who do not completely respond to PDE5-Is.

Adenophora remotiflora protects human skin keratinocytes against UVB-induced photo-damage by regulating antioxidative activity and MMP-1 expression

BACKGROUND/OBJECTIVES: Chronic ultraviolet (UV) exposure-induced reactive oxygen species (ROS) are commonly involved in the pathogenesis of skin damage by activating the metalloproteinases (MMP) that break down type I collagen. Adenophora remotiflora (AR) is a perennial wild plant that inhabits Korea, China, and Japan. The present study investigated the protective effects of AR against UVB-induced photo-damage in keratinocytes. MATERIALS/METHODS: An in vitro cell-free system was used to examine the scavenging activity of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and nitric oxide (NO). The effect of AR on ROS formation, antioxidant enzymes, elastase, MMP-1 level, and mRNA expression of MMP-1 were determined in UVB-irradiated human keratinocyte HaCaT cells. RESULTS: AR demonstrated strong DPPH free radical and NO scavenging activity in a cell-free system exhibiting IC50 values of 1.88 mg/mL and 6.77 mg/mL, respectively. AR pretreatment dose-dependently attenuated the production of UVB-induced intracellular ROS, and antioxidant enzymes (catalase and superoxide dismutase) were enhanced in HaCaT cells. Furthermore, pretreatment of AR prevented UVB-induced elastase and collagen degradation by inhibiting the MMP-1 protein level and mRNA expression. Accordingly, AR treatment elevated collagen content in UVB-irradiated HaCaT cells. CONCLUSION: The present study provides the first evidence of AR inhibiting UVB-induced ROS production and induction of MMP-1 as a result of augmentation of antioxidative activity in HaCaT human keratinocytes. These results suggest that AR might act as an effective inhibitor of UVB-modulated signaling pathways and might serve as a photo-protective agent.

Trends of Studies Published in Asian Oncology Nursing, 2011~2014

PURPOSE: The purpose of this study was to analyze and identify recent trends of published research in Asian Oncology Nursing (AON). METHODS: A total of 140 studies were analyzed using a tool developed by the researchers, focusing on research design, research subject, research themes, and type of interventions and outcome variables of experimental studies. RESULTS: AON lacked studies which were supported by research funds (27.9%), or used an experimental study design (10.0%). In particular, there were only 2 studies (1.4%) conducted with randomized controlled trials (RCT). Research subjects were various, including patients with cancer, family care givers, healthy population, and oncology nurses. Based on a framework of cancer control continuum, most studies addressed issues of the treatment phase, whereas few studies addressed issues of diagnosis, survivorship, or the end-of-life (EOL) phase. Regarding research themes, psychosocial nursing including quality of life, anxiety, and depression was most frequently reported. In the experimental studies, an education program was most frequently applied and psycho-social-spiritual variables and symptoms were most frequently used to evaluate the effects of the intervention. CONCLUSION: The results suggest that further expansion of RCT and studies regarding diagnosis, survivorship, and EOL phases are needed. Also, our findings may contribute toward the development of a Korean oncology nursing research agenda.

Job Analysis Based on Working Hours and Activities of Oncology Advanced Practice Nurses

PURPOSE: The purpose of this study was to analyze the actual working hours of an oncology advanced practice nurse (APN) at a university hospital according to the duties and tasks outlined in the job description. METHODS: An assessment tool for this study was created based on the job description of APN as defined by the Korean Nurses Association, and was later verified by a specialist party. Twenty-three oncology APNs recorded their nursing activity on the assessment tool. The working hours and distribution were analyzed according to specific duty and task. RESULTS: Average working hours per day for APNs totaled 9.3 hours. Time for duties was allocated as follows in order of priority: 28.0% for therapeutic intervention and 19.8% for clinical decision making. Time allotted for tasks was distributed as follows: 19.5% for special nursing care and 9.8% for planning treatment and nursing interventions. CONCLUSION: This study allowed insight into the actual time spent by oncology APNs on duties and tasks outlined in the job description. These findings should contribute to management of the changing role of oncology APNs. Furthermore, the results may be used as a basic resource for the continued professional development of the work of oncology APNs.

Study on Sodium Reduction: 'Healthy Restaurant for Sodium Reduction'

This study compared total sodium amounts in 'Healthy Restaurant for Sodium Reduction' menu items located in Seoul, Chungcheong, and Gyeongsang in 2011 and 2012. In addition, this study explored reduced sodium cooking methods in 'Healthy Restaurant for Sodium Reduction'. This study monitored and collected menu samples from a total of 103 restaurants participating in 'Healthy Restaurant for Sodium Reduction' in 2011 and 2012. We also surveyed restaurant employees to identify reduced sodium cooking methods in 2012. The results showed significant reductions in total amounts of sodium in menu items of restaurants located in Seoul, Chungcheong, and Gyeongsang between 2011 (310.8+/-156.8 mg/100g) and 2012 (211.6+/-110.3 mg/100g). Amounts of sodium in all seven foodgroups showed significant reductions between 2011 and 2012: 'Gook/Tang' (from 226.6+/-127.7 mg/100g to 168.5+/-74.3 mg/100g), 'Jjigae/Jeongol' (from 385.8+/-111.7 mg/100g to 257.1+/-82.53 mg/100g), 'Noodle/Dumpling' (from 263.8+/-116.9 mg/100g to 194.1+/-55.6 mg/100g), 'Gui' (from 390.3+/-120.6 mg/100g to 258.8+/-92.7 mg/100g), 'Steamed dish' (from 305.3+/-124.3 mg/100g to 175.6+/-76.6 mg/100g), 'Bob' (from 273.7+/-162.5 mg/100g to 167.1+/-93.1 mg/100g), and 'Stir-fried dish' (from 368.6+/-116.6 mg/100g to 219.0+/-72.4 mg/100g). The survey results showed that responses for 'Reducing salt amount' were 75.7%, responses for 'Using enchovy stock, shrimp, radish, or fruit soup' were 64.1%, and responses for 'Liking the taste because it is bland' were 50%. This study indicates that 'Healthy Restaurant for Sodium Reduction' nutrition policy was successful for reducing sodium contents of restaurant menu items, and also consumers were satisfied with the tastes.
