Human being does work to live out and they have their private life because human has sociality. Both work and life are important to live out but they are on the trade-off relationship. Because keeping the balance between work and life is too hard, it has been interested by academic and practical areas. Definition of Work-life balance here is that balance or imbalance arising between work and life has no negative impact on their daily life. Above all, Work-life balance is important because it is strongly related to identity. Recently, the introduction of the mobile office system has emerged as a way to solve the problem of work-life balance. It is based on the teleworking which was formerly generated. Teleworking is to perform the work in the employee's home or office space set aside without going into the workplace. Concept of the mobile office system here is not only using portable devices during work for convenience but also the system which is designed for the performance. Thanks to the diffusion of smart devices(smart phone, tablet pc), mobile office system has been spread. Although the importance of mobile office systems is emerging, there are few researches about it. Even they mostly focus on the standpoint of performance of mobile office system. However, Quality of life is as important as the performance. As a part of Quality of Life field, Work-life balance is the closest to employee's quality of life. So this study aims to examine the effect of the use of mobile office systems on work-life balance. To do so, we try to find factors effecting Work-life balance from existing studies and then set a research model. We set the use of mobile office systems as independent variables which are divided by use of function, use by location and use by situation. There are four dependent variables - sense of self command, sense of balance, solving work problem, solving life problem. We collected data from employees who are using mobile office systems on their job. 215 people were participated in the survey and we used multiple regression analysis to verify our research model. Results show that every independent variable has no impact on solving work problem while they have slight impact on the other dependent variables. Especially use on the business trip has significant effect on dependent variables. It means that there is a possibility use of mobile office system could control the employee's quality of life and system should be evolved until it covers even critical tasks. Also, support for mobile office system -education, encouragement-should be provided. By mobile office system is maturing, future research would be done.

In the future, the ubiquitous computing environment will provide users with context-aware services, intelligently interacting with omnipresent resources and surrounding environments at any location and time. Therefore, the ubiquitous computing environment requires context-aware applications in order to gather and analyze context information in various situations. However, existing context-aware applications have mainly focused on providing services and adapting themselves to users based on user related contexts. But this environment requires not only user related contexts but also Quality-of-Service (QoS) related contexts. In this paper we propose a frame-work for supporting user-oriented QoS in ubiquitous environments. The proposed approach adopts a semantic ontology and a neural network algorithm in order to reason about explicit and uncertain contexts. We also show the possibility of applying the framework to real environments such as collaborative engineering service, automobile maintenance service and ubiquitous home service.

Recently, smart lighting systems are the combination between sensors and lights. These systems turn on/off and adjust the brightness of lights based on the motion of object and the brightness of environment. These systems are often applied in places such as buildings, rooms, garages and parking lot. However, these lighting systems are controlled by lighting sensors, motion sensors based on illumination environment and motion detection. In this paper, we propose an automatic lighting control system using one single camera for buildings, rooms and garages. The proposed system is one integration the results of digital image processing as motion detection, hand gesture detection to control and dim the lighting system. The experimental results showed that the proposed system work very well and could consider to apply for automatic lighting spaces.

The main objective of this research is the development of a logit model of urban workers' auto ownership choice. For the utility specification. a variety of behavioral hypotheses about the factors which affect the urban workers' auto ownership choice are considered. Based on the behavioral hypotheses, a binary logit model of auto ownership is estimated. Empirical estimation is based on a sample of workers taken in Daegu City(1994). The binary logit model of auto ownership development in this paper provides reasonable results in terms of behavioral and statistical considerations. Furthermore, this paper develops several submarket models of auto ownership choice. Market segmentation was made using age, sex, income, home-to-work time distance. It is found that the estimated results with market segmentation are also reasonable. Finally future directions of model development are suggested.

Typically internal mobile LCD display modules are connected to the mobile product baseband PCB with flexible printed circuit board equipped with board-to-board connector. This solution has a drawback of limiting the product concept work to certain solutions that are based on connector size, location, flexible PCB length, bending, etc. in the display module. Also flexible printed circuit board based solutions are not completely optimized from reliability point of view, causing flex circuit board breakings. For the external displays in the PC or Home entertainment market, the cable solution is too expensive and resource demanding. The wireless solution has obvious advantages over reliability, low cost and flexibility. This paper describes a wireless audio-visual interface solution.

This study attempted to explore how middle aged married men and women prospected a Centenarian society and what implications their prospect cast for family policy. We conducted focus group interviews with five groups in order to identify their subjective prospects on marital relations, parent-child relations, caregiving from family or institutions, and alternative living arrangement. From those interviews, we found that married men and women in their 40s, 50s, and 60s possessed ambivalent attitudes toward their marital relationship, either acknowledging an importance of marital relationship or accepting long-standing disrespectful marital relationship. They also had a dualistic perspective on parent-child relationship, accepting parental responsibility for children and even grand-children but maintaining low expectations for children. What they needed was age appropriate opportunities for work or leisure and better community services and facilities. These results showed that the middle-aged was concerned experiencing unprecedented family situations. They needed family life education and services in order to adapt to the Centenarian society. Since family policy has viewed this age group out of service target, programs and services have been underdeveloped for this group. Expecting a Centenarian society however, we need to expand the boundary of family policy and take a new perspective. We need to develop and implement marital education programs, community-based self-care services, and age-appropriated opportunities for work, leisure, and social relations.

The purpose of this study is to examine the relative influence of various characteristics that affect the happiness and family strength of pre-elderly and the elderly. This study also shows the differences between the two age groups. The National Survey of Korean Families has been done by the Ministry of Equality and Family on 2010. Respondents selected from national survey were 1016 pre-elderly and 629 elderly. The results of this study are as follows; first, 66% of the respondents chose health as the condition is being the important elements of their happiness following money, work (job), children, spouse and family life. Second, the group of people considering work and health as important elements of their happiness is happiest, but the group considering money and health as the important elements of their happiness feels a lower level of happiness. Third, the pre-elderly chose health as the most important condition, but the elderly chose subjective economic condition, among the factors affecting family strength. Fourth, family strength affects most on in regard to the happiness of pre-elderly and the elderly. Next, the more they are financially stable, physically healthier and living in rural areas, they feel the happier they feel. Based on the results of this study, further studies are needed to determine components of family strength that both pre-elderly and the elderly consider as important elements of their happiness. Support programs for the elderly without a spouse will increase the well-being of the elderly.

최근 IoT(Internet of Things)는 지속적인 연구를 통해 장소에 한정되지 않고 다양한 분야에 접목되어 활용되고 있다. 그러나 기존 IoT 시스템은 디바이스의 동작이 사용자 중심이 아닌 사용자의 주변환경을 중심으로 이루어지기 때문에 작업의 효율과 정확도가 낮은 문제점이 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 사용자 원격 제어 분석 알고리즘을 제안한다. 사용자가 원격제어를 진행하면 해당 명령을 수집하여 기기, 시간 별로 분류하여 데이터를 정렬한다. 정렬된 데이터를 기반으로 분석을 진행하여 기기들의 시간 별 동작을 도출한다. 분석의 결과를 기반으로 가정 내부의 디바이스를 동작시켜 환경을 제어한다. 이에 따라 사용자에게 맞춤형 서비스를 제공함으로써 디바이스 동작의 정확도와 편의성이 증대될 것으로 사료된다.
