This paper examines the changes in housing characteristics occupied by two or more households from 1995-2005, as a replicated follow-up study done by the previous decade of 1985-1995. The data analyzed were based on the Population and Housing Census in 1995, 2000, and 2005 by the Korean National Statistical Office. Results showed decreasing trends in the percentages of housing units occupied by multi-households and of households sharing a housing unit, while the average number of households for a shared housing unit was increasing. Detached dwellings in dongs (neighborhood) including ordinarily single-family detached ones, mainly multi-family houses, were the most often shared with other households even in the trend of the decreasing number of the detached housing. Further research is suggested to focus on housing circumstances of households sharing a detached dwelling in Dongs by the type of detached dwellings.

Studies on time-use have generally concentrated on the amount of time used by each member of a household in Korea. The quality of family relationships could be associated with the amount and types of interactions between family members. This study examined the time that adults spend with their family members on various activities. The purpose of this study is to explore a typology of family time and investigate the characteristics of each type. The data source was the 2009 Time-Use Survey conducted by the Korean National Statistics Office. The people involved in each activity were surveyed for the first time in the 2009 survey in Korea. The data from this study included 10,902 diaries that were filled on weekdays by married adults from ages 20 to 59 years. Data from rural households were excluded. Time use was divided into three categories: family meals, household work and family leisure time. These activities were analyzed using t-test, chi-square analysis and cluster analysis. Family time was classified into four types based on three categories. The four types were named "leisure sharing", "household work sharing", "overall sharing" and "non-sharing". The most common type was non-sharing. The characteristics of each type depended on gender and paid work time. Based on these results, family and labor policies should be developed to increase the work-life balance. Policies that focus on men over 40 years are especially recommended.

We introduce a new multimedia telemedicine system which is called Telemedicine for Real-time Emergency Multi-consultation(TREM), based on multiple connection between medical specialists. Due to the subdivision of medical specialties, the existing one-to-one telemedicine system needs be modified to a simultaneous multi-consulting system. To facilitate the consultation the designed system includes following modules: high-quality video, video conferenceing, bio-signal transmission, and file transmission. In order to enhance the operability of the system in different network environment, we made it possible for the user to choose appropriate data acquisition sources of multimedia data and video resolutions. We have tested this system set up in three different places: emergency room, radiologist's office, and surgeon's office. All three communicating systems were successful in making connections with the multi-consultation center to exchange data simultaneously in real-time.

This study is to perform economic analysis of a PVT-GSHP (Photovoltaic Thermal-Ground Source Heat Pump) system compared to the conventional system which consists of a boiler and a chiller. This research has simulated, developed and analyzed four systems for application in a residential and an office building which was based on the hourly EPI (Energy Performance Index, $kWh/m^2yr$). Case 1 includes a boiler and a chiller to meet heating and cooling demands for a house. Case 2 is the same conventional system as Case 1 for a office. Case 3 is simple summation of Case 1 and 2. And Case 4 is utilizing a PVT-GSHP to meet the combined loads of the house and office. The economic evaluation study was based on IEA ECBCS Annex 54 subtasks C economic assessment methods. This study indicated that PVT-GSHP system can save a building's energy up to 53.9%. Also the SPB (Simple Payback) of the PVT-GSHP system with 0%, 50% initial incentive was 14.5, 6.7 year respectively.

The objective of this study is to explore the perceptions of justice regarding the implementation of flexible work arrangements, as well as to analyze the effects of such arrangements on job satisfaction and organizational effectiveness. The present study posits three key aspects, namely distributive justice, procedural justice, and interactional justice, which are hypothesized to influence individuals' impression of justice in relation to flexible work systems. To investigate the influence of job types on an R&D organization, specifically comparing R&D employees and office management employees, a dataset of 190 R&D employees and 50 office management employees was collected. The findings of the investigation provide empirical evidence that distributive justice has a significant impact on the level of job satisfaction among employees in both research and development (R&D) and office administration roles. Moreover, the influence of work satisfaction on organizational performance is noteworthy, particularly with regard to factors such as job dedication, organizational citizenship behavior, and knowledge sharing. The aforementioned findings offer significant insights for research and development (R&D) firms that have incorporated flexible work arrangements. These insights underscore the significance of emphasizing specific justice perceptions in order to augment job satisfaction and overall performance within the organization.

교통 분야에서 대표적인 공유 사례로 꼽히는 카셰어링(Car Sharing)은 한 대의 차량을 여러 사람이 짧은 시간 단위로 나눠 쓰는 이용 형태로써, 비영리 단체에서 운영하는 NFP(Not For Profit), 수익을 목적으로 민간 기업이 개인을 상대로 운영하는 B2C(Business to Customer), 개인과 개인이 직접 연결되는 P2P(Peer to Peer) 방식으로 운영형태가 구분된다. 이 중 P2P 카셰어링은 개인이 소유한 차량을 공유하는 방식이며 추가적인 차량 구매율을 감소시키고 유휴 차량을 최소화하여 교통혼잡완화 및 효율적인 교통수요관리가 가능하다는 장점이 있다. 본 연구는 공유 개념을 도입한 교통수요관리 정책 마련 및 지속가능한 교통 체계로의 전환을 위한 전략으로 P2P 카셰어링 도입 방안을 고찰하고, 도입 시에 예상되는 제약사항 및 운영활성화 방안을 제시하였다. 연구의 공간적 범위는 서울시 아파트 단지를 대상으로 하였다. 아파트 단지 내에서는 관리사무소 활용에 따른 운영적 측면에서의 지출규모 최소화가 가능하고 주차면 확보에 큰 문제가 없는 점 등이 P2P 카셰어링을 원활하게 운영할 수 있는 여건으로 판단되었다.

To develop an blue tourism website(BTW) for electronic commerce(EC), information requirements of BTW are defined firstly. We defined information requirements of BTW from two aspects, i.e., front office and back office. Information requirements for front office were derived by consumer purchasing decision process. And information requirements for back office were derived by tourism value chain. Total 29 functions are identified as critical EC related functions of BTW. Among them, 25 functions were investigated into BTW. BTWs were searched by search engines - Yahoo and Empas - to Korean websites. There are 12 specialized BTWs, except one cyber museum website. For 12 websites, 25 functions were probed. By the results, in need recognition stage of blue tourism, only weather information was provided in most websites. In information search stage of blue tourism, package recommendation and various contents were provided in most websites. In consumption stage of blue tourism, traffic information were provided in most websites. And in after - sales service stage of blue tourism, bulletin board function was implemented in most websites. The rest of the functions were scarcely implemented. On the whole, it was concluded that most EC related functions of BTW in Korea were not implemented properly. To improve the status quo, it is expected in the dimension of individual website, that marketing planning, customized service, intelligent service, reinforcing purchasing assistance functions, customer relationship management, and escrow service etc. need to be implemented. And it is expected in the dimension of blue tourism industry, that standardizing product catalog, security assistance policy, information sharing by industrial database, finding referral model of BTW, elevating information mind, revising related laws etc. are needed.
