This paper explores variables that influence the prediction of OTT service experience and free(AVOD)/ paid(SVOD) service use. Research results showed that five variables such as gender, age, personal income, household composition, and e-commerce use experience had a significant impact on identifying OTT service experience and whether to use free or paid services. Also, it was found that the probability of using SVOD increases as they prefer news and drama genres and use OTT services for more time. In summary, those who are relatively young, have a high personal income, and are more adapted to digital environments such as e-commerce are more likely to use SVOD.

The elderly population in Korea is rapidly growing. As the population ages, meals become a greater concern, as physical and psychological health problems are directly affected by dietary life, especially for the lower-income elderly. Although the government provides support through a free congregate meal service, there is a lack of systematic management of this meal service. This study investigates the experience of the elderly, especially the symbolic meaning and issues regarding the congregate meal service in their dietary life, to establish strategies for improving congregate meal services. Qualitative data was collected from ten elderly receivers of meal services through in-depth interviews and data was analyzed using Colaizzi's phenomenological research methods. Overall, 90 significant statements, 13 formulated meanings, and five theme clusters were deduced. The five theme clusters for the importance of meal services to the elderly included the followings: "a real meal", "enjoyment of living", "maintenance of regular life", "place for social life" and "meal of silence". We found that the elderly regarded the congregate free meal service not only as meals to appreciate but also as a form of social life. Furthermore, the elderly did not typically express any complaints regarding congregate meal services because they are free. The results showed that it might be difficult to evaluate the quality of meal services based on the opinions of the service receivers. This study suggests it is necessary to develop multilateral evaluation methods to reflect the needs of the elderly and to improve the congregate meal services at elderly welfare centers.

The purpose of this study was to analyze the characteristics and financial status of credit delinquents utilizing the debt management program of the Credit Counseling and Recovery Service between January-June in 2007. Total sample of 41,355 cases was analyzed using the statistical program SPSS(Version 12.0). For analysis, descriptive statistics, F-test, Scheffe test, t-test, logit analysis and regression analysis were employed. People in the age range of 30-40s, males, high-school graduates, married couples, part-time employees, costfree residents and residents in other regions were relatively high users of the debt management program. Reasons of credit delinquency were diverse and was combined to credit default. However, increases in expenses and income reductions were found to be the most frequent reasons. Financial conditions of delinquents were worse than those of average persons shown on the national statistics. It was also found that age, sex, educational level, occupation, region of residence, home-ownership, reason of delinquency, income and total outstandings of debt were significant determinants of short-term debt burden which was measured by the ratio of monthly payment to income and long-term debt burden which was measured by repayment period.

Analyzing the change in consumption pattern depending on the employment of married women, the spendings in transportation, education, and dining out are increased. The change in consumption patterns depending on the increase of dual-income family can be seen as the increased demand of market service that replaces the household production service. Especially when the employment of married woman from high income class(highly educated, middle-class, upper-class) is increased, they tend to get employed in more professional and highly skilled industries, which leads to higher effect on employment induction, and consequently increasing the labor demand for low-skilled service industry.

Purpose : This study was to analyze the demand for emergency ambulance service and to characterize the factors associated with the demand. Method : The basis for the model was from the actual demand for public emergency ambulance and socioeconomic and geographic characteristics. Multiple regression analyses were done for the related characteristics of public ambulance service. Result : The model explained total demand with a high degree of accuracy : the coefficient of determination($R^2=0.96$). For the regression, the set of variables indicative of low socioeconomic status were all significant. It showed the inappropriate use of public ambulance system. Public ambulance demand increased in higher housing density, low income, male unemployment and female labor force. Conclusion : The demand for public ambulances appeared to be highly predictable, using a simple linear model employing socioeconomic variables, quality of service variables, and land use variables. Low-income families tended, to use the public ambulance system more often than higher income. Area having elderly people or children also made many calls. Estimated demand calls were stable and had a tendency to be similar incident types.

This paper analyzes the machine learning predictions of the economic effects of Busan's strategic industries on the employment and income using the Ridge Regression and Lasso Regression models with regulation terms. According to the Ridge estimation and Lasso estimation models of employment, the intelligence information service industry such as the service platform, contents, and smart finance industries and the global tourism industry such as MICE and specialized tourism are predicted to influence on the employment in order. However, the Ridge and Lasso regression model show that the future transportation machine industry does not significantly increase the employment and income since it is the primitive investment industry. The Ridge estimation models of the income show that the intelligence information service industry and global tourism industry are also predicted to influence on the income in order. According to the Lasso estimation models of income, four strategic industries such as the life care, smart maritime, the intelligence machine, and clean tech industry do not influence the income. Furthermore, the future transportation machine industry may influence the income negatively since it is the primitive investment industry. Thus, we have to select the appropriate economic objectives and priorities of industrial policies.

The purpose of the study was to analyze the functional status of low income elderly living at home according to their socio-economic factors, sensory function, health status, medical service utilization, commodity and types of chronic disease. Method: Functional status was defined by the level of mobility, ADL and IADL categorized as independently functional, mildly impaired, moderately disabled, and severely disabled. The data was collected by home-visit interviews with 567 community dwelling adults who were 65 years of age or more with low a income status subsidized by government in ChonAn. Results: 9.9% of community dwelling older adults were severely disabled, and 44.4% were moderately disabled in their functional status. There were significant differences in the functional status by age, education, religion, and types of family structure. The older adults with hearing impairment or dental problems had a significantly higher rate of severe disability. Self-rated health status and medical service utilization were also significant factors to the differences in functional status. The functional status of older adults was also significantly related to the presence of chronic health problems such as chronic back pain, stroke, and Alzheimer-dementia. Conclusion: The results confirmed that community dwelling older adults with low income status were more functionally disabled in comparison to general older adults at national level, while the relating factors to their functional status seemed similar to other studies on older adults. Further studies were suggested to look into functional status longitudinally and focus on the changes of functional status by managing modifiable influencing factors.
