The culture industry is viewed as a driving industry in the 21th century. Korea has experienced the rapid growth rate of the cultural industry in terms of sale amounts for the period of 2004-2009. The purposes of this study are to analyze the spatial pattern of the cultural industry and to empirically examine the effect of municipalities' cultural industries on regional economy using SUR model. The major findings are as follows: First, cultural industries are concentrated in the capital region and several metropolitan areas. Secondly, the estimated result of SUR model shows that there is inter-relationship between cultural industry and regional economy. The effect of the cultural industry on GRDP is that the cultural industry increased 1%, GRDP increased by 0.46%. In turn, GRDP increased 1%, cultural industry increased by 0.75%. Thirdly, the elasticity of the cultural industry on GRDP is much higher than that of labor or capital stock, showing that the cultural industry has a more powerful influence on its regional economy. Fourth, the elasticity of the cultural industry on GRDP of Gun is higher than that of shi, indicating that it is rational for Gun to develop strategies to promote competitive power of the cultural Industry for regional economic growth.

Self-directed learning ability is more important than before. It is well-known that traditional teacher-directed lecture class, seminar-like oral presentation class, and even discussion/debate class have not been enough to enforce self-directed learning ability for students. To resolve the problem, a new dynamic complex instruction model (DCIM) was developed for undergraduate and graduate students and a basic frame of DCIM was published by Oh (2010). Here, it is examined if the application of DCIM to a biology class of graduate school can cause improvement of self-directed learning ability. For this, the self-directed learning readiness scale (West & Bentley, 1990) translated by Ryu (1997) and motivation scale (Hayamizu. 1997) translated by Oh (2001) were employed, and then measurements performed with the translated scales were done in the beginning and the last of two DCIM-adapted graduate biology classes at K university, Daegu, South Korea in the first semester of the year 2010. The results show that self-directed learning ability could be significantly improved through the DCIM-adapted class, compared to the result of a teacher-directed lecture class as a control group. With respect to the motivation, there was not found any statistically significant difference between control and experiment groups of graduate students. The present study seems to be meaningful in that it is the first work proving the effect of improvement of self-directed learning ability of graduate students through the DCIM-adapted classes.

The effects of job related factors on psychosocial health status were examined by taking job stress into account. The self-administered questionnaires were performed, during the period between Oct. 1st, 2009 and Nov. 30th, 2009, to 805 individuals in the service of general administration located in Daejeon City. Causal relationships between job related factors, job stress, and, psychosocial health status were examined by structural equation model. The main finding as follows: For correlations of such indices of psychosocial health status as PWI and MFS with various studied items, all of these two indices were found to be in a negative correlation with the job position, job career, satisfaction in job life, autonomy of job, supervisors support and coworkers support, whereas in positive correlation with the experience of sick absence per year and job demand. With the analysis of structural equation model, the degree of job stress factors was more influential on the level of psychosocial health status than job related factors in such a manner as that the greater the job stress, while the lower the job related factors, the higher the psychosocial health status(PWI and MFS). Moreover, it was found to have the inter-relational effects that the greater the job related factors, the lower the job stress factors. Thus the effective strategy for stress and fatigue symptoms reduction among governmental employees requires additional programs focusing on innovated job specifications.

This study is a descriptive study to analyze the hand washing practice of nurses working in clinic applying health belief model. This research involved 162 clinical nurse at G city. The data were collected from Sep 1, 2017 to Oct 31, 2017. The collected data were analyzed using an independent t-test, 1-way ANOVA, pearson's correlation coefficient and multiple regression analysis, where p-values of <0.05 were considered statistically significant by using SPSS 20.0. The overall practice of hand washing by general subjects were high 3.1 in all subjects, but there was no statistically significant difference. Health beliefs about hand washing practice according to general characteristics showed significant difference in perceived benefits (p<0.05), and there was a significant difference in perceived benefits and perceived barriers in age(p<0.05). In regard to the correlation among the subfactor of health beliefs, benefits had a statistically significant negative correlation to barriers and, positively correlated to cues to action. The results of this study suggest that continuing education of infection management in hospitals considering health beliefs about proper hand washing training will enhance hand washing practice.

This study aims to examine whether the life satisfaction of the elderly living alone is influenced by demographic background, economic activity, productive leisure participation and the moderating effect of social support. Data in this study was from 5th Korean Retirement Income Study, and 890 elderly living alone were extracted and analyzed, and a multi-level analysis was used to analyze the data because the life satisfaction of the elderly living alone has a random effect according to the region. The results of this study were as follows; First, the elderly living alone showed high life satisfaction when they live in province rather than Seoul or metropolitan city, spend higher living expenses, do economic activities, and they are economically independent. Second, those who participated in productive leisure activity were more satisfied with life than those who did not, and those who have social support are more satisfied with their life. Third, the relationship between productive leisure participation and life satisfaction was moderated by social support. When the elderly living alone participate in productive leisure activities, they feel more life satisfaction according to social support given to them.

This study investigates the prediction of daily water supply, which is a necessary for the efficient management of water distribution system. Fuzzy neuron, namely artificial intelligence, is a neural network into which fuzzy information is inputted and then processed. In this study, daily water supply was predicted through an adaptive learning method by which a membership function and fuzzy rules were adapted for daily water supply prediction. This study was investigated methods for predicting water supply based on data about the amount of water supplied to the city of Kwangju. For variables choice, four analyses of input data were conducted: correlation analysis, autocorrelation analysis, partial autocorrelation analysis, and cross-correlation analysis. Input variables were (a) the amount of water supplied (b) the mean temperature, and (c)the population of the area supplied with water. Variables were combined in an integrated model. Data of the amount of daily water supply only was modelled and its validity was verified in the case that the meteorological office of weather forecast is not always reliable. Proposed models include accidental cases such as a suspension of water supply. The maximum error rate between the estimation of the model and the actual measurement was 18.35% and the average error was lower than 2.36%. The model is expected to be a real-time estimation of the operational control of water works and water/drain pipes.

We investigated whether divergent thinking attitudes mediate the relationship between self-esteem and creative teaching beliefs among teachers. We examined differences in the mediating model we proposed in the groups of pre-service and in-service child care teachers. We found differences in the pre-service and in-service child care teachers in the proposed mediating model. Especially in the pre-service child care teachers, the mediating effect of divergent thinking attitudes was confirmed. There was a significant effect from self esteem to creative teaching beliefs and also a significant effect from divergent thinking attitudes to creative teaching beliefs. But in-service child care teachers, there was neither direct nor indirect effect of self-esteem to creative teaching beliefs. Suggestions for more studies and for better in-service education for the pre-service and in-service child care teachers are recommended for the future.

This research suggested a real-time traffic signal control algorithm using individual vehicle travel times on an isolated signal intersection. To collect IDs and passing times from individual vehicles, space-based surveillance systems such as DSRC were adopted. This research developed models to estimate arrival flow rates, delays, and the change rate in delay, by using individual vehicle's travel time data. This real-time signal control algorithm could determine optimal traffic signal timings that minimize intersection delay, based on a linear programming. A micro simulation analysis using CORSIM and RUN TIME EXTENSION verified saturated intersection conditions, and determined the optimal traffic signal timings that minimize intersection delay. In addition, the performance of algorithm varying according to market penetration was examined. In spite of limited results from a specific scenario, this algorithm turned out to be effective as long as the probe rate exceeds 40 percent. Recently, space-based traffic surveillance systems are being installed by various projects, such as Hi-pass, Advanced Transportation Management System (ATMS) and Urban Transportation Information System (UTIS) in Korea. This research has an important significance in that the propose algorithm is a new methodology that accepts the space-based traffic surveillance system in real-time signal operations.

This study aims to observe the effect of age friendliness of cities on life satisfaction and to suggest ways to improve quality of life of older people. The secondary data sets were used in this study, which were '2014 Survey of Living Conditions and Welfare Needs of Korean Older People.' It's a nationwide data collected by the Korean Institute of Health and Social Affairs. A multilevel analysis model was used to analyze the data because the level of age friendliness has a hierarchical data structure. Results showed as follows: First, life satisfaction of older adults is affected by the level of age-friendliness of cities in which they live. Second, on the personal level, older people showed low life satisfaction when they are more older and have more chronic diseases and more depressed. On the contrary, life satisfaction of older adults increased when they have higher education and income. Third, on the city level, older people showed higher life satisfaction when they live in high employment rate area and participation rate of lifelong education. Cautions should be placed when interpret the result because the variables that represent the characteristics of age friendless of cities were constituted arbitrary. Based on the results, suggestions for improving the city environment age-friendly and implications for social welfare practice were provided.
