Relationship between Peer Relationships and Problematic Smartphone Use among Female Adolescents: The Mediating Effect of Depression

Purpose@#This study examined the mediating effects of depression on the relationship between peer relationships and problematic smartphone use in female adolescents. @*Methods@#Secondary analysis was performed on data from the Korean Children and Youth Panel Survey in 2018, a national survey conducted by Korea’s National Youth Policy Institute. Data from 1,141 female adolescents were analyzed using descriptive statistics, with independent t-test and 1-way analysis of variance, Pearson correlation coefficient, and multiple linear regression analysis. The significance of the mediating effect was verified using PROCESS macro model 4. @*Results@#The direct effects of both positive and negative peer relationships increased problematic smartphone use in female adolescents. Negative peer relationships increased problematic smartphone use via the mediating effects of depression, whereas positive peer relationships reduced problematic smartphone use via the mediating effects of depression. @*Conclusion@#Problematic smartphone use among female adolescents can be reduced by lowering the incidence of depression and developing interventions aimed at helping them resolve conflicts with friends and cope with negative emotions.

Effect of Acculturative Stress on Multicultural Adolescents’ Life Satisfaction: Sequential Multiple Mediating Effects of Bicultural Acceptance Attitude, Self-Esteem, and Social Withdrawal -Using the 2016 Multicultural Adolescents Panel Study-

Purpose@#This study determined acculturative stress’ effect on the life satisfaction of multicultural adolescents based on Roy’s Adaptation Model and some earlier studies. Further, it examined the sequential multiple mediating effects of bicultural acceptance attitude, self-esteem, and social withdrawal on life satisfaction. @*Methods@#Participants included 1,163 multicultural adolescents who participated in the sixth Multicultural Adolescents Panel Study. A hypothesis test was conducted using Hayes’ Process Macro Model 81. @*Results@#Life satisfaction increased with a decline in acculturative stress. Each of bicultural acceptance attitude, self-esteem, and social withdrawal had a single mediating effect on the relationship between acculturative stress and life satisfaction in multicultural adolescents. The sequential multiple mediating effects of bicultural acceptance attitude and self-esteem were confirmed significant after their impact on the relationship between acculturative stress and life satisfaction was analyzed. Bicultural acceptance attitude and social withdrawal were found to have a significant sequential multiple mediating effect on the relationship, as well. @*Conclusion@#This study’s results demonstrate that acculturative stress reduction is critical to improving multicultural adolescents’ life satisfaction. Bicultural acceptance attitude, self-esteem, and social withdrawal have a single mediating or sequential multiple mediating effect on the relationship between multicultural adolescents’ acculturative stress and life satisfaction. The findings, which highlight mediating effects, indicate that by increasing bicultural acceptance attitude and self-esteem, and reducing social withdrawal, multicultural adolescents’ life satisfaction can be improved.

Effect of Lifestyle Intervention Program for Overweight and Obesity Pregnant Women

Purpose@#This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue andpregnancy stress, blood pressure, and neonatal birth weight, using Cox’s interaction model of client health behavior for overweight andobese women. @*Methods@#This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52patients who met the selection criteria, including 25 in the experimental group and 27 in the control group, were the subjects of the study;they comprised overweight and obese pregnant women who were receiving prenatal care at A and B women’s hospital in J province. Thelifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, andprofessional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017. @*Results@#This study showeddifferences in the appropriate weight gain rate (x2=6.17, p=.013), suppression of an increase in fatigue (t=-2.32, pp =.012), and an increasein pregnancy stress (t=-1.87, p=.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birthweight (p>.05) were found. @*Conclusion@#The study findings indicate that this program could be an effective intervention for the control ofappropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox’s interaction model of clienthealth behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.

The Effect of Video Education on Cancer Patient Advance Directive Writing

Purpose@#This study was conducted to examine the role of video education on cancer patient advance directive writing. @*Methods@#To evaluate the effects of video education on cancer patient advance directive knowledge, attitude, writing intention and writing, this study employed a non-equivalent control group and non-synchronized design as a quasi-experimental study. The target population of this study were adults aged ≥50 years old, diagnosed with cancer in South Korea. The proximity population were also cancer patients who visited a university hospital. The control group (n=31) were educated verbally using a leaflet and the experimental group (n=30) were educated by a video program developed by the National Bioethics Policy Institute for 10 minutes, supplemented with a leaflet. The advance directives video program form provided by the Korean Ministry of Health and Welfare was used. @*Results@#The experimental group showed a positive change in knowledge level (F=52.82, p<.001, effect size=0.96), attitude (F=12.21, p<.001, effect size=0.46), the intention to write (F=18.22, p<.001, effect size=0.56) advance directives and a higher proportion of writing (χ2=13.87, p<.001) than the control group. @*Conclusion@#The results of this research show that providing information through video is a more effective educational medium for retention of knowledge, attitude, writing intention, and writing of cancer patient's advance directives.

Academic Achievement of Nursing College Students according to Academic Self-efficacy: The Mediating Effect of Major Satisfaction

PURPOSE: The purpose of this study was to examine the mediating effect of major satisfaction in the relationship between academic self-efficacy and academic achievement among nursing students. METHODS: Data were collected from 142 nursing students from March 5 to March 9, 2018, and the collected data were analyzed using SPSS version 21.0 for Windows. RESULTS: Academic self-efficacy had a significant effect on both major satisfaction (β=.31, p<.001), and academic achievement (β=.43, p<.001). The parameter of major satisfaction was found to have a significant effect on the dependent variable, academic achievement (β=.22, p=.007), and the independent variable, academic self-efficacy, also had a significant effect on academic achievement (β=.39, p<.001). Thus, major satisfaction was found to have a partial mediating effect on the relationship between academic self efficacy and academic achievement. The Sobel test showed that the path of the academic achievement and academic self efficacy variables was significantly mediated by major satisfaction (Z=2.99, p=.003). CONCLUSION: Academic self-efficacy was found to affect academic achievement, and major satisfaction was found to play a partial mediating role in the relationship between academic self efficacy and academic achievement.

Effects of a Moderate Drinking Program based on Social Cognitive Theory on College Students with Drinking Problems

PURPOSE: The purpose of this study was to investigate the effect of the moderate drinking program based on social cognitive theory on changes in the drinking habits of college students with drinking problems. METHODS: This study included a total of 68 college students with drinking problems. These participants participated in 10 sessions of a moderate drinking program in which social cognitive theory was applied. Changes in the cognition and behaviors of the participants were then investigated. RESULTS: The moderate drinking program based on social cognitive theory for college students with drinking problems was effective in increasing the subjects' drinking-related knowledge (U=191.50, p<.001), enhancing their drinking refusal self-efficacy(t=8.02, p<.001), and changing their drinking-related attitudes (U=108.50, p<.001), drinking outcome expectancy (t=8.68, p<.001), amount of drinking in a single session (χ²=25.72, p<.001), number of drinking sessions per month (x2=10.05, p=.006), and problem drinking behaviors (t=5.77, p<.001). CONCLUSION: These results can be used to inform a regular on-campus intervention programs for moderate drinking, and to implement education about moderate drinking, thereby increasing the success rate of drinking reduction.

The Effect of Pain Relieving Intervention During Infiltration among Gamma Knife Surgery Patients for Stereotactic Frame Fixation

PURPOSE: This study aimed to compare the effects of three interventions on pain, blood pressure, and pulse rate during infiltration anesthesia in patients about to undergo gamma knife surgeries. METHODS: The three interventions employed in a university-affiliated Hospital in J City, South Korea were as follows: EMLA cream plus Vapocoolant spray (Vapocoolant, n=30), EMLA cream plus 10.0% Lidocaine spray (Lidocaine, n=30), and EMLA cream only (EMLA, n=30). The equivalent control-group pre test - post test study design was used. Pain was assessed subjectively using the numeric rating scale (NRS) and objectively using a Galvanic Skin Response (GSR) tester. NRS scores were assessed after infiltration anesthesia and the GSR was assessed during infiltration anesthesia. Blood pressure and pulse rate were assessed twice: before and after infiltration anesthesia. Data were collected between August 3, 2016 and March 24, 2017. RESULTS: NRS scores after infiltration anesthesia and the GSR during infiltration anesthesia were significantly lower in the Vapocoolant group than in the Lidocaine and EMLA groups (F=13.56, p < .001 and F=14.43, p < .001, respectively). The increase in systolic blood pressure (F=4.77, p=.011) and in pulse rates (F=4.78, p=.011) before and after infiltration anesthesia were significantly smaller in the Vapocoolant group than in the Lidocaine and EMLA groups; however, no significant differences were observed in diastolic blood pressures (F=1.51, p=.227). CONCLUSION: EMLA cream plus Vapocoolant spray was the most effective intervention to relieve pain and to lower increase in systolic blood pressure and pulse rate caused by infiltration anesthesia for stereotactic frame fixation. Thus, application of Vapocoolant spray in addition to EMLA cream is highly recommended as a nursing intervention for patients undergoing gamma knife surgeries.

Effects of a Patient Educational Video Program on Bowel Preparation Prior to Colonoscopy

PURPOSE: The purpose of this study was to evaluate the effects of an educational video program on bowel preparation for a colonoscopy. METHODS: The study used a non-equivalent control group and non-synchronized design as a quasi-experimental research involving 101 participants undergoing bowel preparation for a colonoscopy (experimental group 51, control group 50 subjects) at W. university hospital, from Aug. 7 to Oct. 31, 2013. The control group received verbal education with an explanatory note while the experimental group received education using a video program. To measure knowledge of diet restrictions and compliance with ingesting bowel preparation solutions, a questionnaire, based on The Korean Society of Gastrointestinal Endoscopy's Guide (2003), developed by Sam-Sook You, was used after revisions and supplementation was done. To measure bowel cleanness, the 'Aronchick Bowel Preparation Scale' was adopted. Data were analyzed using the SPSS WIN 12.0 program. RESULTS: A higher proportion of the experimental group showed a positive change in knowledge level on diet restrictions (U=1011.50, p=.035) and ingestion of bowel preparation solutions (U=980.50, p=.019), a higher level of compliance with diet restrictions (U=638.50, p<.001), ingesting bowel preparation solutions (U=668.00, p<.001) and the level of bowel cleanness (chi2=17.00, p<.001) than the control group. CONCLUSION: The results of this study indicate that a video educational program for patients having a colonoscopy can improve knowledge, level of compliance with diet restrictions, ingestion of bowel preparation solutions, and bowel cleanness. Therefore video educational program should be used with this patient group.

Effects of Human Papillomavirus Vaccination Education on College Women's Knowledge, Health Belief, and Preventive Behavior Intention

PURPOSE: This study was done to evaluated the effects of Human Papillomavirus (HPV) vaccination education on college women's knowledge of HPV, health beliefs (perceived severity and perceived susceptibility), and preventive behavior intention. METHODS: A nonequivalent control group pretest-posttest design with repeated measures was used. Participants were 125 female college students in one university, assigned to an experimental group (72 students) and control group (53 students). RESULTS: Two weeks after the intervention, the experimental group reported higher scores of knowledge, perceived severity, perceived susceptibility, and preventive behavior intention than the control group. All follow-up scores except intention measured at 5 weeks after the intervention from the experimental group remained still higher than those from the control group. CONCLUSION: The results suggest that the variable of preventive behavior intention which is believed to be the closest predictor of real vaccination rate could be affected by the education, but did not remain at the same level at 5 weeks. Therefore, additional interventions may need to be provided before the educational effect on preventive behavior intention is greatly diminished.

The Effects of Self-efficacy and Social Support on Depression in Elementary School Children

PURPOSE: The purpose of this study was to investigate the effects of self-efficacy, social support, and depression in elementary school children. METHODS: The participants of this study were 619 students from seven elementary schools located in Jollabuk-do Province, Korea. The methods included data analysis, descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and stepwise multiple regression using SPSS/WIN version 15.0. RESULTS: The mean scores of self-efficacy, social support, and depression were 2.9+/-0.58, 3.2+/-0.44 and 14.0+/-7.32, respectively. There was a significant positive correlation between self-efficacy and social support (r=.517, p<.001). Significant negative correlations were observed between self-efficacy and depression (r=-.557, p<.001) and between social support and depression (r=-.571, p<.001). The variables of depression in elementary school children were self-efficacy and social support, which explained 42.7% of the cases. CONCLUSION: The findings from this study suggest that current intervention programs are not sufficient to curb depression in elementary school children and therefore it is needed to develop nursing intervention programs to promote self-efficacy and social support.

A Predictive Model of Health Promotion Behavior in Obese School-Age Children

PURPOSE: The purpose of this study was to propose and to test a predictive model that could explain and predict the health promotion behavior of obese school-age children in Korea. METHODS: Participants for this study were 365 students from 13 elementary schools located in Jeonbuk Province, Korea. The data were analyzed using SPSS 15.0 program and Amos 7.0 program. RESULTS: The results verified the factors that influence health promotion behavior of the participants. Important direct factors were prior health-related behavior, perceived self-efficacy, and commitment to a plan of action and indirect factors were perceived barrier and activity-related effect. These factors explained 75.3% of variance in the participants' health promotion behavior. The proposed model was concise and extensive in predicting health promotion behavior of the participants. CONCLUSION: Findings may provide useful assistance in developing effective nursing interventions for maintaining and promoting health promotion behavior in obese school-age children.

A Study on Activities of Daily Living and Perceived Health Status of Disabled Persons at Home in Rural Areas

PURPOSE: This study was attempted to provide basic data required to develop community-base rehabilitation program for disabled persons at home by investigating their characteristics, ADL, and perceived health status. METHOD: The subjects were 146 disabled persons at home in rural areas. Data were collected from January 22 to January 31, 2004. Data were analyzed using frequencies, percentages, means, standard deviations, minimums, maximums, chi2-test, Fisher's exact test, t-test, one-way ANOVA, Scheffe test, Contingency coefficient, Pearson's correlation, Stepwise multiple regression. RESULTS: The average score of ADL was 5.51+/-1.92: sphincter control (5.85+/-2.10), communication (5.66+/-2.02), transfers (5.67+/-2.21), self care (5.44+/-2.05), social cognition (5.33+/-2.08), and locomotion (4.85+/-2.32). This means that the respondents were in the state of dependence. The main items requiring others' help were 'bathing' (57.7%) and 'going up and down stairs' (51.1%). ADL was significantly different according to age, gender, occupation, medical fee payer, type, severity and duration of disability, BMI, and alcohol drinking. Among the respondents, 82.8% perceived that their health status was bad. Main factors influencing the perceived health status of disability were age and ADL(R2=.343). CONCLUSION: Perception of health status among the disabled is related to their characteristics and ADL, so it is necessary to develop community-base rehabilitation programs in order to improve ADL and the perception of health status.

Knowledge, Attitude and Behavior Related to Obesity in Elementary School Children

PURPOSE: This study was carried out to investigate the knowledge of obesity and exercise, attitude to dietary habits and exercise, and physical activities and exercise in elementary school children to provide basic data for obese programs. METHODS: The subjects were 850 elementary school children of grade 3-6 in C City and data were collected with a questionnaire. RESULTS: Higher grade, female and overweight children recorded a higher knowledge score than lower grade, male and normal weight children. As for attitude to dietary habit, lower grade and female children had more positive attitude than higher grade and male children. Overweight children were more aware of the seriousness of exercise than normal weight children. In physical activity, lower grade and male children were higher than higher grade and female children. The more interested the children's family were in exercise, the higher score of physical activity they showed. CONCLUSION: In planning education for preventing obesity, it should give consideration to lower grade and male children. In addition, education for changing dietary habit attitude must be extended to higher grade and male children as well. It is effective to develop and apply physical activity improvement programs in the cooperation and involvement of their families.

PURPOSE: This study was to investigate the needs of health & community services among the disabled at home in rural areas. METHODS: The subjects were 146 persons with disabilities living in J-gun. The questionnaire was based on the needs of 8 categorical services. Data were analyzed using frequency, percentage, mean, standard deviation, minimum, maximum, t-test, one-way ANOVA and Scheffe test. RESULTS: Among the respondents, 27.4% visited the public health center in community for rehabilitation therapy. The average score of need was 2.62+/-.79: education services (2.92+/-1.05); medical services (2.81+/-.82); nursing care services (2.75+/-1.08); connection services (2.62+/-1.20); housing services (2.60+/-1.09); emotional services (2.41+/-1.03); other services (2.24+/-1.06); and support of self-sustenance service (1.92+/-1.15). The items in highest need were medical checkup (70.7%), medication (62.1%), traditional oriental therapy (60.4%) and physical therapy (58.9%), and those of lowest need were device repair (8.7%) and guidance of facility admission (7.1%). Needs were significantly different according to age (F=4.751, p=.001), employment status (t=2.108, p=.037) and medical fee payer (F=5.061, p=.002). CONCLUSION: The needs of education & medical services were relatively high. Demographic factors were statistically significant in determining needs. For the disabled at home in rural areas, more various services or programs should be executed based upon the needs and characteristics of based upon the needs and characteristics of the subjects.

Smad4 Expression in Gastric Adenocarcinoma

BACKGROUND: The role of Smad4 in carcinogenesis is important, because of its function as a central mediator of TGF-beta signaling. In the present study we analyzed the expressions of Smad4 mRNA and protein in human gastric cancer cell lines and tissues and we also analyzed their clinicopathological significance. METHODS: We used semi-quantitative RT-PCR for Smad4 mRNA expression in 13 cases of fresh gastric cancer tissues and two gastric cancer cell lines (MKN-28, SNU-1). We also used immunohistochemistry for Smad4 protein expression in 88 cases of formalin fixed gastric cancers tissues. RESULTS: The mRNA level of Smad4 was higher in MKN-28 cell line (intestinal type) than in the SNU-1 cell line (diffuse type). Fresh frozen gastric cancer tissues showed that the intestinal type of gastric cancer had higher Smad4 mRNA expressions than the diffuse type of gastric cancer (p<0.05). Immunohistochemical staining for Smad4 revealed that cytoplasmic and nuclear expressions of Smad4 were significantly correlated with histologic types of gastric cancer (p<0.05). That is, the intestinal type of gastric cancer showed more cytoplasmic and nuclear smad4 expressions than did the diffuse type of gastric cancer. Reduced cytoplasmic expressions and positive nuclear expressions of Smad4 were more prominent in the advanced gastric cancer than in the early gastric cancer. CONCLUSION: Taken together, we suggest that loss of Smad4 expression might be associated with the intestinal type of gastric cancer. Also reduced cytoplasmic Smad4 expressions and increased nuclear Smad4 expressions may be associated with the advanced stage of gastric cancer.

A Study on the Smoking Related Social Influence, Refusal Skill and Nonsmoking Related Self-efficacy among Adolescents / 아동간호학회지

PURPOSE: This study was to investigate the smoking related social influence, refusal skill and nonsmoking related self-efficacy among adolescents. METHOD: The subject for this study consisted of 3,000 students of middle and high school located in Chonbuk province. The data were collected by self-report questionnaire from Aguest 19 to September 14, 2002. RESULT: The smoking rate was 3.3% in middle school students and 13.6% in high school students. The subject have had 61.1% of family members, 42.7% of same sex friends, 39.4% of object sex friend, 64.9% of peer group and 85.9% of teachers were being smoke. The smoking related social influence and smoking status showed significant relationship; current smokers' smoking related social influence level was much higher than former and never smoker. Friends', teachers' and family members' influences were important to adolescents' smoking. Adolescents had social influence made by many smokers. 27.7% of subject were suggested to smoke by near people, 40.4% of which them were smoked or tried to smoke. The mean refusal skill score of subject was 39.13 points per hundred. Adolescents have showed very low level of refusal skill to smoke. Current smokers' refusal skill level was significantly lower than former and never smoker. The mean average nonsmoking related self-efficacy score of current smoker was 44.46 percents per hundred, it showed that current smoker had very low level of self-efficacy to ceasing smoke. CONCLUSION: For the purpose of adolescents smoking prevention and ceasing, the educational program must designed to reduce smoking related social influence, to promote the refusal skill and nonsmoking related self-efficacy.

Correlation between Histopathologic Grade, Stage, and Degree of EGFR Expression in Transitional Cell Carcinoma of the Urinary Bladder

This study was performed to estimate the correlation between the histopathological grade and the clinical stage, which are known as important prognostic factors, and EGFR expression status in 57 cases of transitional cell carcinoma of the urinary bladder. There was a significant correlation between the histopathological grade and clinical stage of transitional cell carcinoma of the urinary bladder and between expression grades of EGFR and histopathological grades, or clinical stages of transitional cell carcinoma of the urinary bladder. Therefore, the presence of a high intensity of EGFR staining in the transitional cell carcinoma of the urinary bladder was associated with poor differentiation and invasion. On the basis of the above results, it was suggested that the degree of EGFR expression is one of the objective and reliable prognostic factors in transitional cell carcinoma of the urinary bladder.

Sertoli-Leydig Cell Tumor of Hemangiopericytoma Pattern: A case report

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.
