The aim of this study was to investigate whether there is the association between parents residence type and connubial bliss mediated to Korean married women. A total of 3,851 married women were selected from the database of the Fourth Korea Longitudinal Survey of Women and Families(KLoWF) in 2015-2016. In univariate analysis, there was statistically significant differences parents residence type, couple activity, family care and connubial bliss according to socio-demographic characteristics. Moreover, when the parents residence type is short distance, connubial bliss is higher, couple activity is more active and family care is more friendly attitued. By the result of sobel test, parents residence type was indirectly influenced on connubial bliss mediated to couple activity and family care. However, parents residence type was no directly influenced on connubial bliss mediated. The results of these studies will help design policy plans to improve the relationship between spouses and family members in a universal nuclear family society.

The purpose of this research is to explore the explanatory factors of preference for the universality of the welfare system at the time of expanding the welfare system. In particular, considering endogenous problem that may occur in the process of analyzing the causal relationship between subjective perception and preference for welfare policy, the 2SLS regression analysis using instrument variables was attempted in this research. The key findings of this research were as follow. First, the groups who are opposed to the welfare state expansion, for example high income earners, low risk group, and employer/self-employer, prefer the more universal welfare systems. Second, the negative perception of welfare policy and recipients, which is stronger in older generation who experienced a much longer period of industrializaion, have a negative effect on preference for the universal welfare system. Last, we find that the endogenous problem arise in this research and distort the estimated regression coefficients. Therefore, subsequent studies must be mindful of this problem when they explain attitudes with attitudes.

음성 인식 기술이 발달함에 따라 음성 인식 기술을 이용한 응용의 개발이 중요한 문제로 떠오르고 있다. VoiceXML은 전화기를 통한 음성 인터페이스를 위한 XML 언어로서 손쉬운 방법으로서 음성 인터페이스를 설계, 구현할 수 있도록 만들어진 언어이다. 본 논문에서는 이를 이용해 전화를 통하여 음성으로 자동차 정보 안내 시스템을 사용할 수 있는 사용자 인터페이스를 구현한다. 구현된 시스템 및 서비스는 VoiceXML의 장점을 활용하여 원거리에서 편리하게 사용자가 자동차의 정보를 안내받고 제어할 수 있는 인터페이스 자체보다는 음성 인터페이스의 설계 및 구현에 중점을 두었다. 10인의 피실험자가 각 10회씩 총 100회를 실험한 결과 99.3%의 인식률을 보였다. 추후 차세대 자동차 텔레메틱스 서비스와 연동하면 구현되어진 시스템의 활용이 증대될 것이라 판단된다.

The purposes of this study were compare the leisure attitudes, leisure activities, and leisure constraint among three different generations - teenagers, adults, and elderly adults. Data were obtained from a Questionnaire completed by both male and female lived metropolitan, and aged over 13. Using the factor analysis, this study classified the types of leisure attitudes. The leisure attitude was divided to 4 factors - reducing stress, self-realization, family activity, and surplus time. In order to compare the attitudes, activities, and constraints of leisure among three different generations, ANOVA was used The findings of this study are as follows: First, there were significant differences between teenager group and the others. The teenagers (n=107) recognized the leisure as a mechanism of reducing stress, or as just surplus time. They liked sports, computer games, travels, and reading books, but were not likely to like leisure activities shared with family members. Their leisure constraints were significantly larger than those of the other groups. Teenagers' constraints of time, money, and skills could be leisure barriers. Second, adults group (n=123) attached importance to the family leisure activities. They liked to spend time with their family members, but they seemed to be relatively passive in most types of leisure activities. They like to read newspapers and magazines, and to participate in religious activities. Third, elderly adults' (n=86) purpose of leisure activities was to improve the health condition, and to develop relationships with their friends. They liked sports such as swimming and aerobic dance, travels, religious activities and community service activities. Their good health condition and economic resources could decrease the leisure constraints.

The main purpose of this research is to investigate the qualitative nature of Korean adolescents and their parent's perception of elderly parents care. In addition, this research exams the quantitative differences between the two generations in term of their elderly parents care self-efficacy and attitude towards caring for their elderly parents. Further, an examination of the parental influence upon their children's elderly parents care self-efficacy and attitude towards caring for their elderly parents. There were 2,460 participants in this study, with 820 adolescents, and 820 fathers and 820 mothers. The results of the study were as follows: First, in terms the participants perceptions of "the most difficult aspect of caring for elderly parents", the most representative response for adolescents was financial difficulties, while for parents differences in opinions. When it came to "the best aspect of caring for elderly parents" the most representative response for adolescents was harmonious family, while for parents good for children's upbringing. When it came to "actual acts (behavior) of elderly parents care" the most representative response for adolescents was living together with their elderly parents, while for parents looking after their elderly parents. When it came to "the best method of caring for their elderly parents" the most representative response for both adolescents and parents was providing a peace-of-mind for their elderly parents, followed by the second most frequent response of adolescents living together with their elderly parents, and for parents talking with their elderly parents. When it came to "how one feels when not caring for their elderly parents" the most representative response for both groups was a feeling of indebtedness. Second, for the quantitative analyses of the differences between the two generations, the parents showed a lower level of elderly parents care self-efficacy and a higher level of negative attitude towards caring for their elderly parents, when compared to the adolescents. Third, for the parental influence upon the adolescents' elderly parents care self-efficacy and attitude towards caring for their elderly parents, the only significant influence found was the mothers' elderly parents care self-efficacy.

최근 대학생들은 초등학교 때부터 혹은 중학교 때부터 급식을 받아온 세대로 급식체계에 싫증을 내고 학교 밖의 외부식당으로 눈을 돌리고 있는 세대이다. 또한, 위탁급식전문업체의 대학 내 급식사업 참여와 많은 선행 연구 등을 토대로 여러 면에서 대학 내 구내식당이 개선되고 있으나 아직도 매우 부족한 실정이다. 따라서, 본 연구는 외부식당과의 경쟁으로 현재 급식인원수가 매년 감소하여 운영상의 어려움을 겪고 있는 S 대학 학생식당 고객의 급식소 선택속성에 대한 의견을 조사하고 현재 운영중인 급식소 이외에 추가 설립하고자 하는 식당 신설에 대한 전략을 도출하고자 한다. SPSS통계 package (ver. 11.0)를 활용하여 기술통계(descriptive analysis), 컨조인트 분석 (conjoint analysis)을 실시하였다. 현재 학생식당 이용빈도 감소원인은 ‘음식이 맛이 없어서’가 44.8%, ‘거리가 멀기 때문’이 19.9%로 조사되어, 학생식당의 이용빈도에 가장 큰 영향을 주는 것은 '음식 맛'과 '거리'인 것으로 파악되었으며, 학생식당에 대한 전반적인 만족도는 ‘보통이다’가 37.8%, ‘불만족 한다’가 36%, ‘매우 불만족한다’가 18.4%, ‘만족한다’가 7.8%로 조사되어 응답자의 대부분이 식당에 대해 불만족하고 있었다. 거리에 의해 식당의 이용빈도가 감소하고 있는 것은 현 학생식당의 위치가 강의 동과 먼 거리에 위치하고 있어 강의 동이 밀집해 있는 건물과 근거리에 식당이 개설된다면 이용할 의사가 있는지 여부에 대해 64.7%가 이용하겠다는 의사를 밝혔고 26.1%는 이용하지 않겠다고 응답했다. 따라서, 학생들이 인식하는 적정 거리의 식당 위치를 파악하기 위해 식당으로 이용하는 소요시간에 대해서 조사대상자가 멀다고 인식하는 시간과 가까운 거리라고 인식하는 시간에 대한 조사 결과 가까운 거리로 인지하는 평균 이동소요시간(분)은 5분이었으며 먼 거리로 인지하는 평균이동소요시간은 10.9분으로 적당한 식당의 위치는 S~10분내의 거리로 9분 30초의 거리에 식당이 위치하면 학생들의 이용률을 극대화시킬 수 있을 거라 사료된다. 사전 대면면접을 통해 가격, 소요시간, 음식의 맛으로 선정된 속성과 각 속성별 수준을 활용한 컨조인트 분석 실시하여 도출된 학생들의 급식소 선택 시 중요하게 인식하는 속성은 가격대, 소요 시간, 음식 맛 순으로 나타났으며, 각각의 중요도는 가격이 65.42%, 소요시간인 24.76%, 음식의 맛이 9.82%였다. 즉, 학생들은 학생식당의 서비스 품질 속성 중에서 상대적으로 식사 가격을 가장 중요하기 생각하는 것으로 나타났고, 다음으로는 식사를 하기 위해 식당까지 가는데 소요되는 시간, 음식의 맛을 중요하게 생각하는 것으로 분석되었다. 컨조인트 분석결과 조사대상자가 가장 선호하는 대학 식당으로는 이동하는데 6-10분이 소요되는 거리에 위치한 식당으로 2,100-2,500원 정도의 가격대로 맛있고 깔끔한 식당을 가장 선호하는 것으로 조사되었다. 따라서, 현재 운영중인 학생식당이 모두 1,800원의 단일 식단가로 운영되고 있는 점을 감안하여 학생식당을 신설할 경우에는 이동하는데 10분 이상 소요되지 않는 장소에 가격대는 현재보다 더 높은 2,000-2,500원의 가격대에서 맛있고 깔끔한 현재와는 차별화 된 일품메뉴 위주의 식단의 학생식당을 신설하는 것이 바람직할 것으로 사료된다.

Conventional RF signal-based indoor localization techniques such as BLE or Wi-Fi based fingerprinting method show considerable localization errors even in small-scale indoor environments due to unstable received signal strength(RSS) of RF signals. Therefore, it is difficult to apply the existing RF-based fingerprinting techniques to large-scale indoor environments such as airports and department stores. In this paper, instead of RF signal we use the geomagnetic sensor signal for indoor localization, whose signal strength is more stable than RF RSS. Although similar geomagnetic field values exist in indoor space, an object movement would experience a unique sequence of the geomagnetic field signals as the movement continues. We use a deep neural network model called the recurrent neural network (RNN), which is effective in recognizing time-varying sequences of sensor data, to track the user's location and movement path. To evaluate the performance of the proposed geomagnetic field based indoor positioning system (IPS), we constructed a magnetic field map for a campus testbed of about $94m{\times}26$ dimension and trained RNN using various potential movement paths and their location data extracted from the magnetic field map. By adjusting various hyperparameters, we could achieve an average localization error of 1.20 meters in the testbed.
