  • In this study, the Slab Ocean Model (SOM) is coupled with an Atmospheric General Circulation Model (AGCM) which developed in University of Kangnung based on the land surface model of Biosphere-Atmosphere Transfer Scheme (BATS). The purposes of this study are to understand radiative role of clouds considering of the atmospheric feedback, and to compare the Clouds Radiative Forcing (CRF) come from the analyses using the clear-cloud sky method and CGCM. The new CGCM was integrated by using two sets of the clouds with radiative role (EXP-A) and without radiative role (EXP-B). Clouds in this two cases show the negative effect $-26.0\;Wm^{-2}$ of difference of radiation budget at top of atmosphere (TOA). The annual global means radiation budget of this simulation at TOA is larger than the estimations ($-17.0 Wm^{-2}$) came from Earth Radiation Budget Experiment (ERBE). The work showed the surface negative effect with $-18.6 Wm^{-2}$ in the two different simulations of CRF. Otherwise, sensible heat flux in the simulation shows a great contribution with positive forcing of $+24.4 Wm^{-2}$. It is found that cooling effect to the surface temperature due to radiative role of clouds is about $7.5^{\circ}C$. From this study it could make an accurate of the different CRF estimation considering either feedback of EXP-B or not EXP-A under clear-sky and cloud-sky conditions respectively at TOA. This result clearly shows its difference of CRF $-11.1 Wm^{-2}$.

  • This study was based on the experience of dental hygienists' role conflict, and attempted to grasp the nature of the dental hygienist role conflict factor, constituent factor and coping. Giorgi's phenomenological method was used to analyze data collected through in-depth interviews with nine dental hygienists working in a dental clinic. The analysis revealed three central meanings: task scope, role conflicts, and role conflict management style and limitations. In the first category, task scope, the range of the legal scope, and the duties performed by the dental hygienist differed slightly. The second category included role conflict due to interpersonal relationship, work, work environment, competence, and identity as a professional because of role conflict. The third category included the role conflict management style and limitations. Dental hygienists tried to solve the role conflict situation through various efforts. In the face of the reality that the conflict is not solved despite such efforts, the dental hygienists felt the limitation and chose to leave. Dental hygienists are dissatisfied with their roles because of confusion regarding professional values and lack of awareness of the professional workforce due to differences between legal scope and actual practice. Based on the results of this study, it is necessary to develop a tool to quantitatively measure the level of role conflict in dental hygienists and to conduct follow-up studies on the effects of coping strategies by role conflict situations.

  • Background: There has been considerable interest in Japanese society in the problem of work-related stress leading to depressive symptoms, and an increasing number of primary houseworkers maintain paid employment. The purpose of this study was to examine the differential impact of multiple roles associated with psychological distress among Japanese workers. Methods: We studied 722 men and women aged 18-83 years in a cross-sectional study. The K10 questionnaire was used to examine psychological distress. Results: The proportion of participants with psychological distress was higher in women (17.8%) compared with men (11.5%). Having three roles significantly decreased the risk of psychological distress [women: odds ratio (OR), 0.37-fold; men: OR, 0.41] compared with only one role. In working married women, there was significantly less psychological distress (OR, 0.27), and those with childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.38) than those with only an employment role. Similarly, working married men who had childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.41) than those who had only an employment role. Conclusion: The present study demonstrated that participants who had only an employment role had an increased risk of psychological distress. The degree of psychological distress was not determined solely by the number of roles. It is important to have balance between work and family life to reduce role conflict and/or role submersion, which in turn may reduce the risk of psychological distress.

  • Angiopoietin-like 4 (ANGPTL4) has been identified as an adipokine involved in several non-metabolic and metabolic diseases, including angiogenesis, glucose homeostasis, and lipid metabolism. To date, the role of ANGPTL4 in cancer growth and progression, and metastasis, has been variable. Accumulating evidence suggests that proteolytic processing and posttranslational modifications of ANGPTL4 can significantly alter its function, and may contribute to the multiple and conflicting roles of ANGPTL4 in a tissue-dependent manner. With the growing interest in ANGPTL4 in cancer diagnosis and therapy, we aim to provide an up-to-date review of the implications of ANGPTL4 as a biomarker/oncogene in cancer metabolism, metastasis, and the tumor microenvironment (TME). In cancer cells, ANGPTL4 plays an important role in regulating metabolism by altering intracellular glucose, lipid, and amino acid metabolism. We also highlight the knowledge gaps and future prospect of ANGPTL4 in lymphatic metastasis and perineural invasion through various signaling pathways, underscoring its importance in cancer progression and prognosis. Through this review, a better understanding of the role of ANGPTL4 in cancer progression within the TME will provide new insights into other aspects of tumorigenesis and the potential therapeutic value of ANGPTL4.

  • The signal transduction pathway leading to the activation of the p70s6k plays an important role in the progression of cells from G0/G1 to S phase of the cell cycle but remains incompletely characterized. We investigated the role of the Rho family G protein Rac1 in H2O2-mediated p70s6k activation. Transient expression of a dominant negative mutants of the small GTP-binding proteins Rac1 (Rac1N17) and Cdc42(Cdc42N17) showed reduced levels of slower migration on Western blots of one-dimensional SDS-PAGE in p70s6k and ERK1/2 by PDFG stimulation.

Method: The subjects of this study were 193 of the diabetic patients who were visiting 4 Public Health Center in B city. The instrument used for measuring health belief was Park's(1985). for health locus of control was Wallston. et al's(1978) and for sick-role behavior compliance was Park's(1984). The data were collected with structured questionnaires; total 58 items contained about health belief. health locus of control and sick-role behavior compliance from 1st to 31st July. 2001. The data was analyzed by the SPSS/PC programs using t-test. Pearson's correlation coefficient. ANOVA and Scheffe-test. Result: The average score of the health belief was $57.99\pm9.45$ health locus of control was $66.83\pm9.48$ and sick-role behavior compliance was $42.81\pm7.00$. Statistically significant factors influencing the health belief among social demographic characteristics were family number(F=3.818. p=0.024), monthly income(F=5.153, p=0.002), time of diagnosis(F=3.937. p=0.002) and difficult to control disease(F=5.803. p=0.000). The significant factors influencing the health locus of control were marital status(F=4.669. p=0.010). Also significant factors influencing the sick-role behavior compliance were monthly incomes(F=5.245, p=0.000). the time of diagnosis(F=4.424. p=0.001) and admission to hospital with diabetes(F=9.031. p=0.000). There was negative mild correlation comparatively between health belief and sickrole behavior compliance(r=-0.142, p<0.05) but no correlation in sensitiveness/severity, barrier, benefit(p<0.05). There was no correlation between internal. external. chance health locus of control and sick-role behavior compliance (P>0.05). Conclusion: There was a negative weak relationship between health locus of control and patient's sick role behavior compliance. Therefore further study to investigate the relating factor of the sick role behavior compliance among above of middle aged diabetes mellitus patients is necessary.

  • Liver cirrhosis is the common cause of death in Korea today. But, if liver cirrhosis Patients were treated in the early stage of the disease Process, they can have a chance to carry their daily lives with prescribed medical and nursing regimens. Each patient has different health beliefs that there is a different Sick Role Behavior in the process of treatment. In order to increase and control the desired patient's Sick Role Behavior, it is important for nurses to understand the health beliefs influencing Sick Role Behavior. The purpose of this study was to determine factors influencing Sick Role Behavior and provide objective and scientific data to health education, treatment and nursing care. The subjects for this study were 80 Liver Cirrhosis patients selected from in and out patients of the medical department of four University Hospitals in Seoul, Won Joo and Mok Po city. Data was collected from Sep. 18, to Oct. 15, 1984. The measurement tool was the questionaire that developed by the investigator from the literature review based on Health Belief Model. The data Collection was done by interview. Analysis of data was done by use Mean, S.D., ANOVA, Pearson Correlation Coefficient and Stepwise Multiple Regression. The result of study were as follows: 1. The significant influencing variables on the Liver Cirrhosis Patient's Sick Role Behavior in general characteristics were Sex, Marital Status, Educational levels, Family's income and Duration after diagnosis. 2. Between the Sick Role Behavior and Health Belief Model, a) The first hypothesis that the stronger degree of Health Motivation, the higher degree of Liver Cirrhosis Patient's Sick Hole Behavior was supported (r=0.7892, p=0.0000). b) The second hypothesis that the higher degree of perceived susceptibility, the higher degree of Liver Cirrhosis Patients' Sick Role Behavior was supported (r=0.6383, p=0.0000) c) The third hypothesis that the higher degree of perceived severity, the higher degree of Liver Cirrhosis Patients' Sick Role Behavior was supported (r=0.5869, p=0.0000). d) The fourth hypothesis that the higher degree of perceived benefit, the higher degree of Liver Cirrhosis patient's Sick Role Behavior was supported (r=0.7535, p=0.0000). e) The fifth hypothesis that the lower degree of perceived barrier, the higher degree of Liver Cirrhosis Patient's Sick Role Behavior was supported(r=-9.7709, p=0.0000) f) The sixth hypothesis that the higher degree of knowledge in Disease, the higher degree of Liver Cirrhosis patients'lck Role Behavior was supported (r=0.7538, p=0.0000), g) In the correlation among variables, it was found positive correlation except that perceived barrier was negatively correlated. In the Stepwise Multiple Regression and Independent Variables, the factor“Health Motivation”could account for Sick Role Behavior in 62.28% of the Sample (F=128. 786, p<0.01). When the factor“perceived barrier”is added to this, it account for 70.38% of Sick Role Behavior (F=93.479, p <0.01) and the factor“knowledge in disease”is also included, it account for 74.78% of Sick Role Behavior (F=75.131, p <0.01). Finally, when the factor“perceived susceptibility”is included, it account for 75.03% of Sick Role Behavior (F=56.329, p <0.01).

  • This study focused on the sex culture and the sexual rights of women, examining the gender-role stereotype that is related to the protection of the sexual rights of female college students and identifying the influence of self- esteem. The research was conducted on gender-role stereotypes, sexual assertiveness, and self-esteem among female university students attending four-year universities in Seoul and Gyeonggi. Four hundred eighty-two copies were used for analysis. The Pearson's correlation coefficient was used to identify the correlation between the variables. Multiple regression analysis was conducted to identify the mediated effects of self-esteem in the effects of gender-role stereotypes on sexual assertiveness. The Sobel test was conducted to confirm that the effects were statistically significant. The results of this study were as follows. First, the gender-role stereotype had negative correlations with self-esteem and sexual assertiveness. Self-esteem had positive correlations with sexual assertiveness. Second, self-esteem was found to be a partial mediating factor when the gender-role stereotype had a statistically significant effect on sexual assertiveness. Therefore, a coping strategy under the influence of the gender-role stereotype is necessary for improving the sexual assertiveness skill of female students. This study also suggests the need for sex role-related education programs or counseling on self-esteem.
