The architecture of the CDMA mobile system (CMS) is developed based on three function groups - service resource, service control, and service management groups. In this paper, the CMS architecture is discussed from the point of view of implementing these functions. The variable length packets are used for transmission. The synchronization clock signals are derived form the GPS receiver. The open loop and closed loop techniques are used for the power control. The internationally accepted signaling and network protocols are employed. The call control for the primary services in designed to provide efficient mobile telecommunication services. The softer handoff is implemented in one card. The mobile assisted handoff and the network assisted handoff are employed in the soft and hard handoffs. The authentication is based on the secret data which includes random numbers. The management functions, which include the location management, resource management, cell boundary management and OAM management, are implemented to warrant the system efficiency, maximum capacity and high reliability. The architecture ensures that the CMS is flexible and expandable to provide subscribers with economic and efficient system configuration. The dynamic power control, adaptive channel allocation. and dynamic cell boundary management are recommended for future work.

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 draws on status quo bias theoretic perspective as a meta-theoretic lens to explain why individuals have resists to adopt smart devices for their tasks. More specifically, we attempted to examine the relationships among user's resist, perceived usefulness and individual productivity in the smart work context. By employing the status quo bias theoretic perspective, we develop and test our research model by using a survey data from 235 individual users. We demonstrate that satisfaction on the current state influence users' resist, and also the users' resist is mediated by perceived usefulness on individual productivity. From the status quo bias view, this study presents an alternative meta-theoretical lens in order to understand individuals' resist in the smartwork context.

본 논문에서 제안하는 컴퓨터 지원 협동 작업 환경에서의 오류 문제를 위한 동시성 제어란 오류 발생 시에 오류도 하나의 명령어로 취급하고 명령어와 오류가 동시에 발생할 시에 명령어를 순서화해 주는 문제에 대한 시스템을 기술한다. 여기서 전체세션 관리자와 지역 세션 관리자는 분산되어 있고 참여자와 응용 프로그램은 복제된 구조를 갖는다. 즉, 전체 각 참여자가 필요한 view를 생성자가 분배한 abstraction으로 각자 지역적으로 생성한다. 이와 같은 과정으로 네트워크가 구성된다. 오류 및 명령어를 처리하는 컴퓨터와 결과가 보여지는 컴퓨터가 서로 다르기 때문에 오류 발생 또는 명령어 입력과 동시에 화면에 보여지지 않는 단절감이 발생한다. 이것을 제거하기 위하여 공유 윈도우에서 발생하는 이벤트의 결과를 지역윈도우에서 투영시키고 순서화 작업이 끝난 결과와 비교해서 다를 경우에만 새로이 뷰를 생성한다.

To investigate the risk factors of low back pain, an epidemiological study was carried out among male workers aged 20-55 employed in an automobile industry in Korea during the time period from February 1993 to October 1995. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionnaires. General characteristics, medical history, work related factors, fatigue, and MMPI were compared between two groups. To clarify the relationship between job related low back pain and radiologic features of lumbar spine, radiographic study was carried out. The resultant data were processed for $x^2-test$, t-test, and stepwise logistic regression to confirm the adjusted odds ratios. The results were as follows: 1. History of back disease, lifting and carrying work, excessive physical fatigue, and weakend back strength of individual workers were directly associated with low back pain. Odd ratios of these 4 risk factors of low back pain were 5.07, 3.34, 1.49, and 1.22 respectively. 2. The frequency of low back pain history was significantly higher in LBP group. 3. Back muscle strength of lumbar spine of LBP group were significantly lower than control group. 4. The workers in LBP group revealed high fatigue symptoms. 5. In MMPI test LBP group showed higher scales in hypochondriasis, depression, hysteria, psychopathic deviate, paranoia, psychasthenia, schizophrenia, and hypomania. 6. LBP group were more frequently involved in lifting and carrying, working in awkward position, bending, twisting and using lower extremities. 7. LBP group were exposed more to vibration during working. 8. In the Analysis of radiographs of lumbar spine, Jacob's line not crossing fourth lumhar disc space, transitional vertebrae and lumbar displacement more than 4.4mm in standing lateral view were more frequently observed in LBP group than control group. Through these results, it is concluded that identification of previous history of back problem, change of work or working environment for workers with previous back problem and measures to relieve both physical and psychological fatigue of the workers are required for optimal management of work-related back problems among workers. In the present study, several results were different from the previous reports: Jacob's line not corssing fourth lumbar disc space, lumbarization, and vertebral slipping (spondylolisthesis) more than 4.4mm are related to backache. Meticulous studies are required to elucidate the difference.

Analysis on Kandinsky's Work as a Case Study of Art Therapy. This study attempts to analyze a work of W. Kandinsky, who placed great emphasis on the relationship between the form and the color of an object, from the viewpoint of art therapy. Most papers related with fine art work analysis approach it from the aesthetical point of view and there are few attempts to interpret art works in terms of art therapy. This study tries to present a new angle to the studies of art therapy Practiced up to now and research is made on its potentiality. With an analysis on the relationship between human psychology, and color and form that convey visual language, research is made on the feasibility of art therapeutic methods through the approaches based on color psychology, Gestalt theory and perception psychology. The final purpose of this study is to apply the results to the development of illustrations, education program for children, and educational instruments and toys that will promote children's healthy emotional growth based on the color psychology and the form psychology of human being. As an initial study, a piece of Kandinsky's work, titled ' CERCLES DANS CERCLE', is analyzed as a case study of art therapy both from theoretical standpoint and from the viewpoint of art therapy. Through this effort, it can be utilized as a new case study of art therapy that will influence human emotion positively and lead to healthful emotional catharsis.

This paper aims to investigate the effects of Smart-Work IT resources on job performance. The survey was conducted amongst the business workers who are currently engaged in domestic major companies as well as small businesses, and analyzed based on the frequency, factor and reliability. Using PROCESS Macro, we conducted an analysis of the relationship between the IT resources and job performance, treating collective intelligence as a mediating parameter. The results of the study are as follows. First, the IT resources of the companies were found to have a meaningful effect on job performance. Second, the IT resources were found to have no effect on employee productivity except through their effect on the collective intelligence. Finally, while openness and cooperation were found to be the aspects of collective intelligence which mediated between IT resources and workflow improvement, participation, openness and cooperation were found to be the aspects of collective intelligence which mediated between IT resources and workflow coordination, In the future, it is necessary to compare quantitatively the financial performance of Smart-Work adopters and others in the same industry or to compare the financial performance before and after introducing Smart-Work dynamically within the same company.

In a view of rapidly changing business environment, the success and competing power of organizations depend on committed, highly motivated and satisfied human resources. Empowerment is mainly concerned with establishing and building trust between management and employees, and motivating their participation. Also, behavioral integrity emphasizing on the characteristics of effective leaders has shown as direct action that strengthens positive consequences in organizations. However, research regarding behavioral integrity is very limited. Based on the Self-determination Theory, this paper investigates the effect of empowering leadership on employee's job satisfaction and work engagement. Multi-group analysis based on behavioral integrity is also analyzed. An online survey was conducted and 298 employees' data were collected. Using structural equation modeling, results suggest as follows. First, empowering leadership had a positive effect on individual's job satisfaction mediated by their work engagement. Second, the result of the multi-group analysis showed that the effect of empowering leadership on work engagement is stronger in the group with high behavioral integrity. Contrary to the prediction, the result doesn't support the moderating effect on job satisfaction. These findings contribute to our understanding of empowering leadership process. Based on the results, several theoretical and managerial implications are discussed.
