This study aimed to provide basic data to assist in developing programs to improve the quality of life after identifying the factors affecting aging anxiety among middle-aged women. The subjects were 256 middle-aged women in Korea. Data were collected from March 8 to April 11, 2019, and analyzed using descriptive statistics, independent t-test, One-way ANOVA, Pearson correlation, and stepwise multiple regression with SPSS/WIN 18.0. This study found that the aging anxiety of the subjects differed significantly according to job and marriage satisfaction. Aging anxiety had a negative correlation with health perceived health (r=-.300, p<.001), resilience (r=-.537, p<.001), satisfaction of married life (r=-.316, p<.001), and self-esteem (r=-.424, p<.000). The factors affecting aging anxiety were as follows: resilience (β=-.47, p<.001), occupation (β=-.19, p=.003), and self-esteem (β=-.19, p=.014) with 36.9% explanatory power (F=14.34, p<.001). To reduce the aging anxiety of middle-aged people, programs will be needed to improve participation in post-middle-aged jobs or social activities and resilience, self-esteem, thereby providing education and mediation that can allow middle-aged women to accept aging positively.

This study investigated the correlation between the participation in health-related decisions and self-care competency and the factors influencing self-care competence of patients with chronic disease. The participants were 518 patients with chronic illnesses who were admitted to a public health center. Using a structured-questionnaire, the data was collected from January 1, 2019 to 31, 2019. The data was analyzed using descriptive statistics, t-tests, ANOVA, Scheffé tests, Pearson correlation coefficients and multiple linear regression with the IBM SPSS/WIN 22.0 program. The mean scores on the participation in health-related decisions and self-care competency were 3.62±0.20 and 4.57±0.34, respectively. The main variables that distinguish significant differences between participation in healthcare decisions and self-care capabilities are gender, age, education level, diagnosis, and subjective health status. Self-care competency was positively correlated with the participation in health-related decisions (r=.66, p=.043). Factors influencing self-care competence were education (β=-2.23, p<.001), health concerns (β=0.14, p=.003), subjective health statues (β=2.57, p=.011), and age (β=-0.36, p=.048). The input variables explained .56 of self-care competence. The results of the study indicate that approaches focusing on enhancing the participation in health-related decisions could potentially improve self-care competency of patients with chronic disease.

With increasing interest of health due to population aging, medical device industry is highlighted as a promising industry. However, Korea medical device industry is not enough market competitiveness compared to global company due to a narrow domestic market and a small company structure. In order to retain the national competitiveness, it is necessary that we have to derive a central technology and its trend. This study has predicted a central technology for medical device industrial using patent network analysis. The central technology is defined as a key technology that is connected to most other technologies and that significantly affects them. For the empirical study, we conducted social network analysis using covariance and correlation coefficient between IPC codes extracted from medical device patents, introduced by Jun(2012). A social network is a social structure of diverse items as well as of human beings. In this study, we set each medical device as a node in an SNA and analyze the Degree values between them. Also, Korea health industrial statistics system are utilized for verification of selected central technology. As a result, we found that the central technology is located on the medical device items, which are listed higher the amount of production. The central technology selected through the proposed methodology will provide a inspiration for establishment of R&D policy.

The purpose of this study is to analyze the effect of discrimination experiences of adolescents currently using regional children's centers on school life adaptation and the moderating effect of parent-child communication in the process. Data from the first sixth year (2016) of the Children's Panel Survey, which was collected by the Central Children's Center, were used. At the time of the survey, the sample was selected from a total of 392 adolescents who were enrolled in the third year of middle school and currently living with their parents. This study analyzed the correlation analysis of variables related to school life adaptation of adolescents using local children's centers, frequency analysis, descriptive statistics analysis, correlation analysis, and control effects to explain the moderating effect. As a result of the analysis, it was found that parent-child communication, a modulating variable, has a buffering effect in the relationship between discrimination experiences and student life adaptation. To this end, it sought to develop practical programs such as communication methods and parent-child camps. The results obtained through this study can be used as basic data to broaden the theoretical discussions on adaptation to school life of local children's centers and to prepare appropriate policy visits to expand the effects of social intervention.

Statistical control charts are useful tools to monitor and control the manufacturing processes and are widely used in most Korean industries. Many Korean companies, however, do not always obtain desired results from the traditional control charts by Shewhart such as the $\bar{X}$-chart, $\bar{X}$-chart, $\bar{X}$-chart, etc. This is partly because the quality charterstics of the process are not distributed normally but are skewed due to the intermittent production, small lot size, etc. In Shewhart $\bar{X}$-chart. which is the most widely used one in Kora, such skewed distributions make the plots to be inclined below or above the central line or outside the control limits although no assignable causes can be found. To overcome such shortcomings in nonnormally distributed processes, a distribution-free type of confidence interval can be used, which should be based on order statistics. This thesis is concerned with the design of control chart based on a sample median which is easy to use in practical situation and therefore properties for nonnormal distributions may be easily analyzed. Control limits and central lines are given for the more famous nonnormal distributions, such as Gamma, Beta, Lognormal, Weibull, Pareto, Truncated-normal distributions. Robustness of the proposed median control chart is compared with that of the $\bar{X}$-chart; the former tends to be superior to the latter as the probability distribution of the process becomes more skewed. The average run length to detect the assignable cause is also compared when the process has a Normal or a Gamma distribution for which the properties of X are easy to verify, the proposed chart is slightly worse than the $\bar{X}$-chart for the normally distributed product but much better for Gamma-distributed products. Average Run Lengths of the other distributions are also computed. To use the proposed control chart, the probability distribution of the process should be known or estimated. If it is not possible, the results of comparison of the robustness force us to use the proposed median control chart based oh a normal distribution. To estimate the distribution of the process, Sturge's formula is used to graph the histogram and the method of probability plotting, $\chi$$^2$-goodness of fit test and Kolmogorov-Smirnov test, are discussed with real case examples. A comparison of the proposed median chart and the $\bar{X}$ chart was also performed with these examples and the median chart turned out to be superior to the $\bar{X}$-chart.

This study, through a review of advanced research, first, examined the attitudes to products traded in import agency shopping malls and the characteristic variables(product characteristic, customer characteristic) that influence the purchasing intention to understand influencing relationship. Second, the role of adjustment in the relationship between the attitude to the products and the purchasing intention was examined by putting the perceived risk to the moderating variables. Third, efficient controllable basic data in the characteristic variables capable of influencing the management of and import agency shopping mall based on the implications was obtained from the above research result. The 126 responses collected from a questionnaire were analyzed using the SPSS 23.0 statistics package, and the analysis result can be summarized as follows. First, the main cause that influences the attitude of treated products in an import agency shopping mall is the country of origin, national image, innovativeness and price perception, not the brand image. Second, the attitude of the products influences the purchasing intention of the import agency shopping mall. Third, the perceived risk partially plays a role as a moderating variable in the relationship between the attitude of products and the purchasing intention.

The purpose of this study is to investigate the drinking status, health behaviors, health related quality of life and depression among female problem drinkers and to examine the impact of their health behavior and health related quality of life on depression. The data of this study were derived from the 5th Korea National Health and Nutrition Examination Survey conducted during January 2010-December 2012. As for the subjects of this study, 328 female problem drinkers were selected who were classified as those with 8 or higher scores in the AUDIT, and complex samples analysis was conducted using the IBM SPSS Statistics version 21.0 software package. The study result showed that the risk of experiencing depression increased among subjects with a high level of perceived stress and subjects with a low level of health related quality of life. In addition, the risk of experiencing depression increased among subjects with 1-4 hours of sleep time compared to subjects with 8 or more hours of sleep time. Accordingly, it would be necessary to pay attention to stress, sleep time and health related quality of life that are related influencing factors for the improvement of depression and mental health of Korean female problem drinkers.

Purpose: To Examine the status of health behavior and identify the influencing factors of health behavior among pregnant women. Method: The participants were 1011 pregnant women who visited outpatient hospital of in Yanbian, China. Participants were interviewed using Chinese version of Edinburgh Postnatal Depression Scale(EPDS), Perceived Social Supports(PSSS), general self-efficacy, and characteristics. Descriptive statistics, t-test, ANOVA, pearson correlation coefficient, binary logistic regression were used for data analysis with SPSS 19.0. Results: The mean score of health behavior was $28.93{\pm}6.59$ scores(0~45 scores). Antepartum depression(OR=0.94[0.90-0.98]), perceived social supports(OR=1.07[1.05-1.09]), self-efficacy(OR=1.36[1.04-1.79]) were predictor of health behavior among pregnant women, on the contrary to this the characteristics of pregnant women were not statistically significant. Conclusion: The implement of the health behavior among pregnant women was not ideal. It's necessary to develop a health behavior intervention focus on antepartum depression, social support, and self-efficacy for pregnant women.

Nursing service quality can vary depending on the work attitude and behavior of nurses. Nursing attitude and behavior that can be described as voluntary and proactive organizational citizenship behavior(OCB). OCB affects the work performance of nurses in clinical practice is very important and organizational justice is an important influencing factors of OCB. The purpose of this study was to determine the influential factors of organizational justice on OCB of nurses. The descriptive-correlational method was applied. The study was carried out less than a 500-bed hospital. Participants of the study included 230 nurses working in secondary hospitals. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression with the 18.0 SPSS/Window program. Considering the components of organizational justice, there was a significant positive correlation(r=.172~.540, p=.000) between OCB and distributive, procedural and interactional justice. Also, Total organizational justice explained 29.1% of total OCB with influencing factor (${\beta}$=.540) and was statistically significant(F=93.777, p=.000). The influencing factors to OCB were distributive justice(${\beta}$=.283) and interactional justice(${\beta}$=.249) except procedural justice. The findings suggest that strategies of nursing management are needed to focus on distributive justice for compensation and interactional justice for social relationship in order to induce nurses' organizational citizenship behavior.
