본 논문은 OTT서비스 이용경험과 무료(AVOD)/유료(SVOD)서비스 이용의사 예측에 영향을 미치는 변인들이 무엇인가에 대해 살펴 보았다. 연구 결과, 성별, 연령, 개인소득, 가구구성형태, 전자상거래 이용경험 유무, 5개 변인들이 OTT서비스 이용경험과 무료/유료서비스 이용 여부를 식별하는데 유의미한 영향을 미치는 것으로 나타났다. 또한, 뉴스와 드라마 장르를 선호하고 OTT서비스 이용시간이 많을수록 SVOD 이용 확률이 높아지는 것으로 나타났다. 요약하자면, 상대적으로 젊으면서 개인소득이 많고 전자상거래와 같은 디지털 환경에 더 많이 적응된 사람일수록 SVOD 이용 확률이 높았다.

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.

본 논문은 기혼여성의 취업으로 인해 발생된 소비패턴의 변화와 그로 인해 야기되는 산업별 산출액의 변화 및 노동수요 파생효과를 추정하였다. 분석 결과, 맞벌이가구 증가에 따라 교통비와 교육비, 외식비, 가사서비스 등의 소비가 증가하였다. 이러한 소비패턴 변화로 인해 교육 및 보건업, 음식 숙박업 등 시장서비스업의 노동수요 증가가 야기되었다. 특히 고학력 및 중산층 이상의 기혼여성의 취업 시 취업유발효과가 높았으며, 그로 인해 저숙련 업종의 노동수요를 파생시킬 것으로 추정된다.

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.

본 연구는 규제항을 도입한 릿지 회귀분석과 라쏘 회귀분석을 사용하여 부산 전략산업의 지역경제에 미치는 효과를 특히 고용과 소득에 대한 영향을 중심으로 머신러닝 기법으로 예측하고 분석하였다. 주요 연구결과는 다음과 같다. 첫째, 고용에 대한 전략산업들의 영향을 릿지 회귀모형과 라쏘 회귀모형으로 추정해보면, 전략산업 가운데 서비스플랫폼, 콘텐츠, 스마트금융산업으로 이루어진 지능정보서비스 산업과 MICE, 특화관광으로 구성된 글로벌관광산업의 순으로 고용을 증가시키는데 기여하고 있다. 둘째, 릿지 회귀모형과 라쏘 회귀모형에 의하면 초기투자 단계인 자율주행차, 항공, 드론 산업으로 이루어진 미래수송기기산업은 고용과 소득을 유의하게 증가시키지 않는 것으로 나타났다. 셋째, 전략산업의 소득에 대한 릿지 회귀모형의 추정계수들을 보면, 지능정보서비스산업과 글로벌관광산업의 순으로 부산지역의 소득을 증가시키고 있다. 넷째, 라쏘 회귀모형에서 라이프케어, 스마트해양, 지능형기계, 클린테크산업 등 4개의 전략산업들은 소득에 유의한 영향을 주고 있지 않는 반면, 지능정보서비스산업과 글로벌관광산업 등 2개의 전략산업들은 소득을 증가시키고 있으나, 장기 투자 산업인 미래수송기기산업은 현재 지역경제와 소득에 부의 영향을 줄 수 있는 것으로 나타났다. 그리하여 전략산업을 선정하고 육성하는데 있어, 부산지역 경제목표와 정책 우선순위를 먼저 설정할 필요가 있다는 점을 시사한다.
