Influence of Ordering Kiosk Nutrition Information Transparency and Information Quality on the Customer Behavioral Intention in Fast Food Restaurants

This study examined the perception and behavior of fast food restaurant customers toward ordering kiosk nutrition information. Specifically, the influence of nutrition information transparency and information quality on behavioral intention and revisit intention were identified. In addition, the difference in the nutrition information transparency and information quality was analyzed according to the health consciousness of the customers. The study employed a self-administered survey that was distributed both online and offline from November 8~22, 2018. The sample of the study was customers who had experienced ordering from the kiosk in a fast food restaurant in the six months prior to taking the survey. A total of 250 (98.0%) respondents completed the survey, which was used for data analysis. As a result, there was a significant relation between transparency and nutrition information quality (P<0.001). The higher the visibility and inferability of the nutrition information, the better the nutrition information quality. Nutrition information quality has a significant impact on the levels of customer satisfaction and revisit intention (P<0.001). For the differences in the transparency and nutrition information quality by health consciousness of customers, the results indicated that groups with high health consciousness (3.74 or higher) perceived a higher transparency and nutritional information quality than those with a lower health consciousness. These findings can form the basis of a strategy in developing nutrition information of ordering kiosks in restaurants. In addition, it can be applied to academia and industry.

Preference and Performance Fidelity of Modified Korean Physician Order for Life-Sustaining Treatment (MK-POLST) Items in Hospice Patients with Cancer / 한국호스피스완화의료학회지

PURPOSE: The Act on Hospice and Palliative Care and Decisions on Life-sustaining Treatment for Patients at the End of Life was enacted in 2016 and has taken effect since 2018 February. The content of this act was based on Physician Orders for Life-Sustaining Treatment (POLST) in the United States and we modified it for terminal cancer patients registering hospice. The object of this study is to investigate preference and implementation rate for modified Korean POLST (MMK-POLST) items in hospice ward.METHODS: From February 1, 2017 to April 30, 2019, medical records regarding MMK-POLST were retrospectively analyzed for all patients hospitalized in the hospice ward of Gyeongsang National University Hospital.RESULTS: Of the eligible 387 total cohorts, 295 patients filled out MK-POLST. MK-POLST has been completed in 133 cases (44.1%) by the patient themselves, 84 cases (28.5%) by the spouse, and 75 cases (25.4%) by their children, respectively. While only 13 (4.4%) out of 295 MK-POLST completed patients refused the parenteral nutrition and 5 patients (1.7%) for palliative sedation, the absolute majority of 288 (97.6%) patients did not want cardiopulmonary resuscitation (CPR) and ventilators and 226 people (76.9%) for pressor medications. Kappa values for the matched strength of MK-POLST implementation were poor for all items except CPR, ventilators and palliative sedation.CONCLUSION: Hospice patients refused to conduct cardiopulmonary resuscitation, ventilators and pressor agents. In contrast, antibiotics, parenteral nutrition and palliative sedation were favored in the majority of patients.

Dual Biocontrol Potential of the Entomopathogenic Fungus, Isaria javanica, for Both Aphids and Plant Fungal Pathogens

Dual biocontrol of both insects and plant pathogens has been reported for certain fungal entomopathogens, including Beauveria bassiana and Lecanicillum spp. In this study, we demonstrate, for the first time, the dual biocontrol potential of two fungal isolates identified by morphological and phylogenetic analyses as Isaria javanica. Both these isolates caused mortality in the greater wax moth, and hence can be considered entomopathogens. Spores of the isolates were also pathogenic to nymphs of the green peach aphid (Myzus persicae), with an LC₅₀ value of 10⁷ spores/mL 4 days after inoculation and an LT₅₀ of 4.2 days with a dose of 10⁸ spores/mL. In vitro antifungal assays also demonstrated a strong inhibitory effect on the growth of two fungi that are pathogenic to peppers, Colletotrichum gloeosporioides and Phytophthora capsici. These results indicate that I. javanica isolates could be used as novel biocontrol agents for the simultaneous control of aphids and fungal diseases, such as anthracnose and Phytophthora blight, in an integrated pest management framework for red pepper.

Diallyl disulfide attenuates acetaminophen-induced renal injury in rats / 한국실험동물학회지

This study investigated the protective effects of diallyl disulfide (DADS) against acetaminophen (AAP)-induced acute renal injury in male rats. We also investigated the effects of DADS on kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL), which are novel biomarkers of nephrotoxicity in renal tissues, in response to AAP treatment. The following four experimental groups were evaluated: (1) vehicle control, (2) AAP (1,000 mg/kg), (3) AAP&DADS, and (4) DADS (50 mg/kg/day). AAP treatment caused acute kidney injury evidenced by increased serum blood urea nitrogen (BUN) levels and histopathological alterations. Additionally, Western blot and immunohistochemistry analysis showed increased expression of KIM-1 and NGAL proteins in renal tissues of AAP-treated rats. In contrast, DADS pretreatment significantly attenuated the AAP-induced nephrotoxic effects, including serum BUN level and expression of KIM-1 and NGAL proteins. Histopathological studies confirmed the renoprotective effect of DADS. The results suggest that DADS prevents AAP-induced acute nephrotoxicity, and that KIM-1 and NGAL may be useful biomarkers for the detection and monitoring of acute kidney injury associated with AAP exposure.

Influence of Additives on the Yield and Pathogenicity of Conidia Produced by Solid State Cultivation of an Isaria javanica Isolate

Recently, the Q biotype of tobacco whitefly has been recognized as the most hazardous strain of Bemisia tabaci worldwide, because of its increased resistance to some insecticide groups. As an alternative control agent, we selected an Isaria javanica isolate as a candidate for the development of a mycopesticide against the Q biotype of sweet potato whitefly. To select optimal mass production media for solid-state fermentation, we compared the production yield and virulence of conidia between 2 substrates (barley and brown rice), and we also compared the effects of various additives on conidia production and virulence. Barley was a better substrate for conidia production, producing 3.43 x 10(10) conidia/g, compared with 3.05 x 10(10) conidia/g for brown rice. The addition of 2% CaCO3 + 2% CaSO4 to barley significantly increased conidia production. Addition of yeast extract, casein, or gluten also improved conidia production on barley. Gluten addition (3% and 1.32%) to brown rice improved conidia production by 14 and 6 times, respectively, relative to brown rice without additives. Conidia cultivated on barley produced a mortality rate of 62% in the sweet potato whitefly after 4-day treatment, compared with 53% for conidia cultivated on brown rice. The amendment of solid substrate cultivation with additives changed the virulence of the conidia produced; the median lethal time (LT50) was shorter for conidia produced on barley and brown rice with added yeast extract (1.32% and 3%, respectively), KNO3 (0.6% and 1%), or gluten (1.32% and 3%) compared with conidia produced on substrates without additives.

Virulence of Entomopathogenic Fungi Metarhizium anisopliae and Paecilomyces fumosoroseus for the Microbial Control of Spodoptera exigua

The beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae) is difficult to control using chemical insecticides because of the development of insecticide resistance. Several pest control agents are used to control the beet armyworm. Entomopathogenic fungi are one of the candidates for eco-friendly pest control instead of chemical control agents. In this study, among various entomopathogenic fungal strains isolated from soil two isolates were selected as high virulence pathogens against larva of beet armyworm. Control efficacy of fungal conidia was influenced by conidia concentration, temperature, and relative humidity (RH). The isolates Metarhizium anisopliae FT83 showed 100% cumulative mortality against second instar larvae of S. exigua 3 days after treatment at 1 x 10(7) conidia/mL and Paecilomyces fumosoroseus FG340 caused 100% mortality 6 days after treatment at 1 x 10(4) conidia/mL. Both M. anisopliae FT83 and P. fumosoroseus FG340 effectively controlled the moth at 20~30degrees C. M. anisopliae FT83 was significantly affected mortality by RH: mortality was 86.7% at 85% RH and 13.4% at 45% RH. P. fumosoroseus FG340 showed high mortality as 90% at 45% RH and 100% at 75% RH 6 days after conidia treatments. These results suggest that P. fumosoroseus FG340 and M. anisopliae FT83 have high potential to develop as a biocontrol agent against the beet armyworm.

Biological Control of Aphid Using Fungal Culture and Culture Filtrates of Beauveria bassiana

Aphids are one of the most destructive pests in crop production such as pepper, cucumber, and eggplants. The importance of entomopathogenic fungi as alternative pest control agents is increasing. Conidia of entomopathogenic fungi are influenced by environmental conditions, such as temperature and relative humidity, and cause slow and fluctuating mortality. These factors have prevented wider application and use of biocontrol agents. For investigation of means of mitigation of such problems, we conducted bioassays with 47 fungal culture filtrates in order to evaluate the potential of secondary metabolites produced by entomopathogenic fungi for use in aphid control. Among 47 culture filtrates cultured potato dextrose broth, filtrate of Beauveria bassiana Bb08 showed the highest mortality (78%) against green peach aphid three days after treatments. Filtrate of Bb08 cultured in Adamek's medium showed higher toxicity as 100% to third instar nymphs of the aphid compared with seven other filtrates cultured in different broths amended with colloidal chitin or oil. The culture filtrates and fungal cultures from media amended with colloidal chitin or oil had lower control efficacies than filtrates without these additives in three different media. These results indicate that the fungal culture fluid or culture filtrate of B. bassiana Bb08 cultured in Adamek's medium has potential for development as a mycopesticide for aphid control.

A Case of Endoscopically Diagnosed Gastric Cancer with Metastasis to Thyroid and Breast / 대한소화기내시경학회지

Metastatic malignant tumors involving the thyroid gland are not as unusual as was once believed. They may in fact be more common than primary cancer of the thyroid, especially if careful screening is performed at autopsy. The origins of primary neoplasms that metasta size to the thyoid are myriad, but reports obviously indicate predminantly cancers of the kidney, breast, and lung and malignant melanoma. Occasienally, metastatic lesions from several gastrointestinal neoplasms such as colo-retal and esophageal carcinoma are seen, but metastasis from gastric cancer is very rare. We have seen one case of thyroid cancer metastasized from the stomach cancer. It simultaneously spread to the breast also and confirmed with gastrofiberscopic biopsy, fine needle aspiration cytology of the thyroid and excisonal biopsy of the breast. We report this case with reriew of literature.
