The purpose of this study is to define the structure and characteristics of the time shared with parents and children. The three specific questions are asked. (1) How much time do parents and children share with? (2) What kind of effects do the demographic factors and the psychosocial factors have on the time shared with parents and children? (3) And how can the families be classified into different types according to the time shared with parents and children? For the empirically proved answers the 161 full0time housewife couples and the 174 wife employed couples in Seoul and Kyoungki-do are surveyed with a self reported time diary and a structured questionare. Such statistical methods as frequency percentage mean tobit analysis cluster analysis oneway ANOVA and Ducan's multiple range test are used to analize the data Main findings from this empirical study can be summarised like this. First the two largest parts of the time shared with parents and children are eating and TV atching. Second the eldest child's age degree of wife's education the number of children wife's employment status family income degree of the family cohesion the couple's attitude toward marriage and role salience are significantly related to the various kind of time shared with parents and children. Third the families are classified by the time shared with parents and children into three types. type 1: the family shared least time with type 2: the family shared passive leisure with type 3: the family shared active leisure with. Type 3 has very distinctive characteristics. This type of family's eldest child is youger than any other family's and this type of family has a full time housewife. And their family cohesion is higher and their couple's relationship is oriented more companionship.

In recent years, leisure time has received increasing attention in Korean society. Despite the growing interest, however, there are very few studies that explored shared leisure time, especially among married couples. In this light, the present study examined variations in shared leisure time by demographic characteristics and associations between shared leisure time and quality of marital relationship. We used the third wave of the national data KLoWF (Korean Longitudinal Survey of Women and Families, 9,997 19-64 years old women). The study sample included 5,965 married women with no prior history of divorce. Results showed that Korean wives reported very little shared leisure time with their husbands. Given that the mean of the shared leisure time reported by employed women was significantly lower than that of the un-employed, we speculated that the time constraint may be one of the major barriers to having leisure time with one's spouse among Korean married couples. Married women in their 30's had the most frequent couple leisure time. The younger wives in their 20s had more cultural leisure time with their husbands, but sharing outdoor leisure time was not related to their age. The higher level of education for women was associated with greater shared active leisure time. However, visiting a husband's family often took place regardless of the wives' education level. After controlling for age, years of education, job status and annual family income, shared active leisure time (i.e., cultural activity and exercise) was positively related to marital satisfaction. Visiting one's own family, however, was not considered a leisure activity for Korean wives. Rather, frequent family visits were related to lower marital satisfaction. Findings shed light on how leisure life of married women with spouses are intertwined with not only their socioeconomic status and but also marital relationship in culturally unique ways.

Algorithms implementing distributed shared memory (DSM) were developed for ensuring consistency. The performance of DSM algorithms is dependent on system and usage parameters. However, ensuring these algorithms to tolerate faults is a problem that needs to be researched. In this study, we proposed fault-tolerant scheme for DSM system and analyzed reliability and fault-tolerant overhead. Using our analysis, we can choose a proper algorithm for DSM on error prone environment.

Studies of leisure time generally have been concentrated on the amount of time spent by each family member in Korea. In this study, the shared leisure time among family members in various leisure activities was mainly investigated. Purposes of this study were to describe how family members spent the leisure time together and to investigate the determinants that affected whether or not family shared leisure time together. The data source was the '2009 Time Use Survey' conducted by the Korea National Statistical Office. The person involved in each activity was surveyed for the first time in the survey. The data from 17,470 diaries(10,359 weekdays and 3,549 Sunday) from 8,745 individuals aged from 20 to 59 who had a spouse were analyzed. The descriptive statistics and logistic regressions were used. On average, married couples spent leisure time together with spouses 36 minutes a day on weekdays and 1 hour and 38 minutes on Sunday, respectively. Parent did with preschool children 5 minutes a day on weekdays and 15 minutes on Sunday, respectively. The shared leisure time with other family and relatives was 22 minutes a day on weekdays and 1 hour and 13 minutes on Sunday, respectively. Although there was a wide variation on the shared family leisure time by the types of activities, the main shared leisure activity was using mass media, which accounts for about two third of all shared leisure time together with family. Independent variables, including the age, sex, education level, working hours, personal income, presence of preschool children, marital status, sex role attitude, and dual or single income earner were the significant determinants of family's or couple's parent-preschool children's shared leisure time on weekdays or Sunday. Based on the results of this study, family and leisure policy were suggested to increase active family shared leisure time.

Recently, shared dockless e-scooter usage has rapidly increased, rather than the station-based shared mobility service, because of convenience. This transition leads to new social problems in urban areas such as increased traffic accidents and hindrance of pedestrian environments. In this study, we analyze the usage characteristics of shared e-scooters in Seoul, and identify factors influencing demand for shared e-scooters by developing a negative binomial regression model. As a result, the usage characteristics show that the average trip distance, the average trip duration, and the average trip speed were 1.5km, 9.4min, and 10.3km/h, respectively. Demographic factor, transport facility factors, land use factors, and weather factors have statistically significant impacts on demand for shared e-scooters. The results of this study will be used as basic data for suggesting effective operation strategies for areas with higher shared e-scooter demand and for establishing transport policies for facilitating shared e-scooter usage.

In the present study, muscle tissues were obtained separately from individuals from Atlantic hairtail population (AHP), Gunsan hairtail population (GHP) and Chinese hairtail population (CHP), respectively. The seven decamer primers were used to generate the shared loci, specific, unique shared loci to each population and shared loci by the three hairtail populations. Here, averagely, a decamer primer generated 64.7 amplified products per primer in the AHP population, 55.7 in GHP population and 56.4 in CHP population. The number of unique shared loci to each population and number of shared loci by the three populations generated by genetic analysis using 7 decamer primers in AHP, GHP and CHP population. 119 unique shared loci to each population, with an average of 17 per primer, were observed in the AHP population, and 28 loci, with an average of 4 per primer, were observed in the CHP population. The hierarchical dendrogram point out three main branches: cluster 1 (ATLANTIC 01 ~ ATLANTIC 07), cluster 2 (GUNSAN 08 ~ GUNSAN 14) and cluster 3 (CHINESE 15 ~ CHINESE 21). The shortest genetic distance displaying significant molecular difference was between individuals' CHINESE no. 16 and CHINESE no. 18 (0.045). In the long run, individual no. 01 of the AHP population was most distantly related to CHINESE no. 19 (genetic distance = 0.430). Consequently, PCR analysis generated on the genetic data displayed that the geographic AHP population was widely separated from CHP population, while individuals of CHP population were fairly closely related to those of GHP population.

The purpose of this study is to provide a practical guide for planning the private and shared space of student housing for one person household by analyzing their satisfaction and preference. The data was collected through a questionnaire-survey from the students of the university in the city of Cheongju, Chungbuk. 191 samples were collected and analyzed by using SPSS-PC. The results are as follows: (1) this survey showed that most students are dissatisfied with private and shared spaces to narrow size, an unpleasant indoor environment, and incomplete facilities. (2) The most preferred housing type is an officetel in one room style because of its convenience. The majority of students preferred a bedroom, bathroom, kitchen and dining room in personal preferential order with a wide room, well-ventilated environment, and reasonable space zoning for planning the private space. Broad personal spaces with shared spaces such as a study room, cafeteria and health zone are in demand for unit planning. Therefore, to provide privacy for personal living and to develop community spirit, there needs to be a movement to better for community living by arranging optional shared spaces.

This study aims to propose a smart city governance logic model that can accommodate more diverse information service systems by mixing hub-and-spoke and blockchain technologies as a data management model. Specifically, the research focuses on deriving the logic of an operating system that can work across smart city planning based on the two data governance technologies. The first step of the logic is the generation and collection of information, which is first divided into information that requires information protection and information that can be shared with the public, and the information that requires privacy is blockchainized, and the shared information is integrated and aggregated in a data hub. The next step is the processing and use of the information, which can actively use the blockchain technology, but for the information that can be shared other than the protected information, the governance logic is built in parallel with the hub-and-spoke type. Next is the logic of the distribution stage, where the key is to establish a service contact point between service providers and beneficiaries. Also, This study proposes the establishment of a one-to-one data exchange relationship between information providers, information consumers, and information processors. Finally, in order to expand and promote citizen participation opportunities through a reasonable compensation system in the operation of smart cities, we developed virtual currency as a local currency and designed an open operation logic of local virtual currency that can operate in the compensation dimension of information.
