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).

There is an increasing concern over arsenic (As) contamination in rice. This study was conducted to develope a prediction model for As uptake by rice based on the physico-chemical properties of soil. Soil and brown rice samples were collected from 46 sites in paddy fields near three different areas of closed mines and industrial complexes. Total As concentration, soil pH, Al oxide, available phosphorus (avail-P), organic matter (OM) content, and clay content in the soil samples were determined. Also, 1.0 N HCl, 1.0 M $NH_4NO_3$, 0.01 M $Ca(NO_3)_2$, and Mehlich 3 extractable-As in the soils were measured as phytoavailable As concentration in soil. Total As concentration in brown rice samples was also determined. Relationships among As concentrations in brown rice, total As concentrations in soils, and selected soil properties were as follows: As concentration in brown rice was negatively correlated with soil pH value, where as it was positively correlated with Al oxide concentration, avail-P concentration, and OM content in soil. In addition, the concentration of As in brown rice was statistically correlated only with 1.0 N HCl-extractable As in soil. Also, using multiple stepwise regression analysis, a modelling equation was created to predict As concentration in brown rice as affected by selected soil properties including soil As concentration. Prediction of As uptake by rice was delineated by the model [As in brown rice = 0.352 + $0.00109^*$ HCl extractable As in soil + $0.00002^*$ Al oxide + $0.0097^*$ OM + $0.00061^*$ avail-P - $0.0332^*$ soil pH] ($R=0.714^{***}$). The concentrations of As in brown rice estimated by the modelling equation were statistically acceptable because normalized mean error (NME) and normalized root mean square error (NRMSE) values were -0.055 and 0.2229, respectively, when compared with measured As concentration in the plant.

Blog is a new global phenomenon, but many research papers about organizational blog have not been shown. In this study the influencing factors of the organizational blog usage are empirically investigated, and several guidelines are suggested to IT professionals who involves the design and implementation of the organizational blog. The research model consists of seven independent variables, one dependent variable, and two moderating variables. The following variables are established as the independent variables; information, interface, service, communication, enjoy, performance expectation, and social influence. Two dimensions such as need and orientation are suggested for the moderating variables, and the actual usage is adopted as a dependent variable. As a result of multiple regression analysis using a stepwise method, the independent variables except for interface and communication affect the actual usage of organizational blogs. The moderating effects for need and orientation are partially supported. The implications of this study are as the followings; (1) The empirical factors affecting the usage of organizational blogs are empirically investigated, (2) The affecting factors vary according to the type of organizational blogs, and (3) Some guidelines are suggested for organizational blog's design.

The purpose of this study was to investigate the factors affecting credit card attitudes, financial management practices, and sound credit card use among college students, and to conceptualize a theoretical model. Earlier studies identified a number of antecedent variables (such as gender, year in college, job experience, amount of allowance, family income, living with parents, having taken a personal financial management course) and intervening variables (such as attitudes towards credit cards and financial management practices) as useful predictors of sound credit card practices. Four hundred and thirty four undergraduate students in Daejeon participated in this study. Stepwise multiple regression and path analysis were conducted. The results of this study were as follows: 1. Students' attitudes towards credit cards were affected by their you in college, whether they were living with their parents, and the amount of their allowance. Similarly, students' financial management practices were affected by their year in college, whether they were living with their parents, the amount of their allowance, and whether and not they had taken a personal financial management course. 2. Sound credit card practices were influenced by students' gender, their year in college, the amount of their allowance, attitudes towards credit cards, and financial management practices. 3. The path-analysis model demonstrates the relationships among the antecedent variables, intervening variables (credit card attitude, financial management practices), and sound credit card use.

This study was performed to determine drying equations of sarcodon aspratus. Drying tests for sarcodon aspratus were conducted in an experimental dryer equiped with an air conditioning unit. The drying tests were performed at three air temperatures of 30$^{\circ}C$, 40$^{\circ}C$ and 50$^{\circ}C$, and two relative humidities of 30% and 50%. Measured moisture ratio data were fitted with the selected four drying models(Page, Thompson, Lewis and simplified diffusion models) using stepwise multiple regression analysis. When the coefficients of determination and root mean square errors of moisture ratio were evaluated for four drying models, the Page model was found to fit adequately to all the drying test data with coefficient of determination of 0.9996 and RMSE of 0.00523.

Purpose: The purpose of this study was to investigate the difference in serum ferritin and leukocyte regarding overweight and obese South Korean adults. Methods: This study was conducted on 5,281 subjects older than 19, according to data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-3), 2015. Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and stepwise multiple regression analysis (SPSS 24.0). Results: First, serum ferritin and leukocyte were higher regardubg obesity, followed by being overweight and within normal weight. Second, body mass index (BMI) was positively correlated with serum ferritin and leukocyte. Third, factors affecting serum ferritin were gender, and being obese and overweight. Explanatory power of the model was 26.2%. Factors affecting leukocyte were gender, obesity, being overweight, and weight change over the past year (weight gain). Explanatory power of the model was 10.2%. Conclusion: Obesity and being overweight were factors affecting serum ferritin and leukocyte, and obesity was more affected than being overweight in Koreans older than 19. In conclusion, serum ferritin was a marker of inflammation, rather than iron status, in overweight and obese Korean adults.
