  • There has been a notable increased interest of the study of emotions in educational contexts. The purpose of this study was to analyze predicting emotional variables of self-regulated learning strategies and self-handicapping strategies with the university students. Participants were 143 students of undergraduates at A University and B University. Collected data were analyzed by correlation analysis and regression analysis, respectively. It turned out that class related emotions, learning related emotions, and test emotions predicted self-handicapping strategies negatively. However, achievement emotions didn't predict self-regulated learning strategies. The result of this study will provide the theoretical basis and practical usefulness of academic emotions.

  • Objectives This study aimed to examine differences in the hepatic function disorders and prevalence rates of liver diseases in accordance with the Sasang constitutional type, and to analyze whether Sasang constitution is a significant risk factor for fatty liver. Methods A total of 1211 patients who underwent health check-up at the Ilsan Hospital of Dongguk University and had their physical constitutions diagnosed by a specialist in Sasang constitutional medicine from October 31, 2011 to September 28, 2012 were used as the subjects of this study. Presence of hepatobiliary diseases was analyzed from the results of the hepatic function test, lipid test and viral hepatitis infection marker test in the biochemistry tests, and abdominal ultrasonography. Results & Conclusion Subjects of the study were composed of 691 males and 520 females and, in terms of Sasang constitution distribution, 550 Taeeumin, 343 Soeumin and 318 Soyangin. As the results of analysis of prevalence rates in accordance with Sasang constitutions, significant differences were observed in the prevalence rates of abnormal groups in the cases of AST, ALT, GGT, Triglyceride, HDL-cholesterol and LDL-cholesterol, and all of their prevalence rates were in the descending order of Taeeumin, Soyangin and Soeumin. Soeumin displayed significantly higher positive rate for HBs Ab in comparison to Taeeumin and Soyangin. In the results of abdominal ultrasonography, the prevalence rates of fatty liver displayed significant differences and were in the descending order of Taeeumin, Soyangin and Soeumin. And as the result of logistic regression analysis in order to find the risk factors of fatty liver, the Sasang constitution was found to be a significant risk factor for fatty liver. The odds ratio of Taeeumin in fatty liver was found to be 1.634 higher than Soeumin and 1.773 higher than Soyangin

  • Even though software developing environment has been changing to Web basis very fast, there are just few studies of quality metric or estimation model for Web software. In this study after analyzing the correlation between the risk level and property of objects using linear regression, six middle sized industrial system has been used to propose the correlation model of size and Number of Classes(NOC), size and Number of Methods(NOM), complexity and NOC, and complexity and NOM. Among of six systems 5 systems(except S06) have high correlation between size(LOC) and NOM, and four systems(except S04 & S06) have high correlation between complexity and NOC / NOM. As Web software architecture with three sides of Server, Client and HTML, complexity of each sides has been compared, two system(S04, S06) has big differences of each sides compleity values and one system(S06) has very higher complexity value of HTML, So the risk level could be estimated through NOM to improve maintenance in case of that the system has no big differences of each sides complexity.

  • Background: The type of payment is one of the important factors that has an effect on the health of employees, as a basic working condition. In the conventional research field of occupational safety and health, only the physical, chemical, biological, and ergonomic factors are treated as the main hazardous factors. Managerial factors and basic working conditions such as working hours and the type of payment are neglected. This paper aimed to investigate the association of the type of payment and the exposure to the various hazardous factors as an heuristic study. Methods: The third Korean Working Conditions Survey (KWCS) by the Occupational Safety and Health Research Institute in 2011 was used for this study. Among the total sample of 50,032 economically active persons, 34,788 employees were considered for analysis. This study examined the relation between the three types of payment such as basic fixed salary and wage, piece rate, and extra payment for bad and dangerous working conditions and exposure to hazardous factors like vibration, noise, temperature, chemical contact, and working at very high speeds. Multivariate regression analysis was used to measure the effect of the type of payment on working hours exposed to hazards. Results: The result showed that the proportion of employees with a basic fixed salary was 94.5%, the proportion with piece rates was 38.6%, and the proportion who received extra payment for hazardous working conditions was 11.7%. Conclusion: The piece rate was associated with exposure to working with tight deadlines and stressful jobs. This study had some limitations because KWCS was a cross-sectional survey.

  • Objectives: About for twenty years, immigrant women in South Korea have steadily increased due to economic growth and industrialization. According to previous studies in terms of immigrants, subjective socio-economic status(SES) as well as objective SES such as income, occupation and level of education predict health outcomes. The purpose of this study was to examine association between subjective social status and perceived health among immigrant women. Methods: We analyzed 12,531 participants from the 2012 National Survey of Multicultural Families. Study variables included subjective SES in Korea, subjective SES in community and perceived health. Control variables were age, household income, employment, education, marital status, ethnicity, language proficiency. For this study, descriptive analysis, Chi-square test, and multivariate logistic regression analysis were performed. Results: Among immigrant women, after adjusting for control variables, level of education in community was not associated with perceived health. Otherwise, subjective social status in Korea(low subjective social status reference group vs high subjective status : OR 2.056) was associated with perceived health. Conclusions: Immigrant women in Korea would be culturally affected by inherent characteristic rather than social economic status. Through this study, in order to improve health inequality among immigrant women, we should consider developing social supports and networks.

  • Objectives: The purpose of this study was to investigate the hygiene behaviors according to obesity in adolescents and to provide basic data for school health project. Methods: The data from the 10th Korea Youth Risk Behavior Web-based Survey(KYRBWS) were analyzed by STATA 13.0 statistical packages. The demographic characteristics were analyzed by frequency analysis. The relationship between obesity and hygiene behaviors according to demographic characteristics were analyzed by chi-square test. Pearson's correlation coefficient was used for the correlation among the variables. Multivariate logistic regression analysis was performed to examine the effect of obesity on the hand washing and oral hygiene behaviors. The significance level for significance was set at 0.05. Results: Obesity, hand washing before eating and hand washing after using the bathroom were significant negative correlation. Hand washing before eating and hand washing after using the bathroom were significant positive correlation. Hand washing after using the bathroom were positive correlation with toothbrushing after lunch. Washing before eating was 1.079 times higher than that of obese people(p<0.05), and toothbrushing after lunch was higher by 1.298 times in Odds ratio than normal weight(p<0.001). Conclusions: There is a need to develop a school dental health program by collecting hygiene behaviors such as obesity, hand washing, and brushing after lunch.

  • Objectives: This study aims to examine hypertension patients' quality of life by using the data of the 7th Korea National Health and Nutrition Examination Survey (1st year, 2016), identify the factors related to this, and utilize the results as basic data for intervention that can improve hypertension patients' quality of life. Methods: For the research subjects, this study extracted 1,531 patients who were diagnosed with hypertension by a doctor from the total sample of 8,150 participants of the 7th Korea National Health and Nutrition Examination Survey, and selected 1,072 patients with no missing value in the variables to be analyzed as the final research subjects. The SPSS(version25.0) program was used for the analysis of the collected data. Then, this study used a backward elimination multiple regression analysis method that applied complex sample, to examine the factors related with the finally estimated quality of life. Results: The results of this study revealed that hypertension patients' quality of life was related with age, occupation, spouse, household income, weight gain, restriction of activity, subjected health status, perceived stress, and presence of comorbidity. The final model explained 37.0% of the variance (Wald F=30.012 p<.001). Conclusions: When an intervention program is implemented for the improvement of hypertension patients' quality of life in the future, it will be effective to construct the program according to age group, employment, marital status and household income. As for the program operation, patients should get help therefrom to control weight, facilitate activities and relieve their stress, and they should be also motivated to feel healthy. Furthermore, education should be offered so that they appropriately manage their underlying disease at an early stage.
