Objectives : This study was to investigate the relationship analysis in VDT(visual display terminal) of work hours. Methods : Questionnaires were completed by 41 women in VDT operations. The information was used to estimate multiple regression for the VDT of work hours related factors association. Results : The prevalence of the VDT of work hours was significantly higher in the shoulder which followed by the neck, the hand and fingers, the arms, the lowback, the back. The VDT of work hours decreased with aging. The VDT of work hours increased with work duration, single, lower among habitual exercise. The desk height, the seat pan height, the posture on the sitting, the elbow angle all did not meet the recommended criteria. Conclusions : Data from this study support a statistically significant association with satisfaction for occupation.

A fact that limits a company's ability to achieve more of its goal is referred to as a 'constraint' shipbuilding industries need to identify and manage constraints. The theory of constraints is evolved out of the problems of bottleneck formation. This happens and is conserved for the formulation if various real time problems for arriving standard uniquely addressed problems If, for example, the goal of a shipbuilding industry is to make money now and in the future, it is suggested that TOC will enable th mangers of the company to do so. TOC, focuses the organization scare resources on improving the performance of the true constraints, and therefore the bottom line of the organization. An attempt is made for the implantation of the theory into real world shipyard decision support mechanism.

In this paper, we investigates accident actual conditions of electric outlet for low voltage that is used into interior and clear hazardous factor. Electric outlet for general can know that melting of socket-outlet and carbonization of support occur if a contaminant becomes burnout because is flowed in. Existent outlet consists of structure that special quality is good but inflow of a contaminant is easy when is dry. But, waterproof outlet passes silicon layer and have connected structure plug. As developed outlet covers whole surface and back side, interval was shut. Safety pin of developed outlet was established to operate to vertical direction. Therefore, we estimate that contribute on prevention of electrical disaster if use developed outlet to a restaurant, a laundry, a laboratory etc.

In this paper, regulation for form work in standard specification among Korea and foreign countries are studied and compared. Within the scope of this paper, regulation regarding fabrication of form and form removal are mainly focused on. Standard specification prescribed by construction temporary equipment association provides detailed regulations and well arranged. ACI 347-04, CEB-FIP and BS EN 13670 had different style and scope compared to domestic specification. Especially, regulation for form removal in ACI prescribed in terms of minimum period.

본고의 목적은 기존의 교통계획 모형이 가지는 제반 문제점을 GIS와 전문가체계를 교통계획과정에 통합함으로서 얻을 수 있는 편익을 살펴보는데 있다. GIS의 통합에서는 GIS network data를 교통계획모형의 network data로 변환하는 작업이 중추적인바 본고에서는 GIS의 위상학적 data 체계를 변환시킬 수 있는 방안이 제시되었으며, 전문가 시스템의 통합은 복잡한 교통계획 모형의 사용에 있어서 사용자와 대화를 통한 모형입력의 자동화와 교통계획과정에서 생겨나는 애매모호한 여러판단작업(judgmental issues)의 효율적 처리를 통해서 전체적인 교통계획과정을 쉽고 편리하게 하는 측면에서 검토되었다. 또한 양자의 통합을 계기로 전반적 계획과정에 feed back 기능을 부여함으로써 종래의 순차적인 모형에서 발생하는 문제점을 극복하려는 시도도 해 보았다. TranDASS(Transportation Decisio Aid and Support System)라는 PC상의 구현을 통해서 상기의 통합이 이루어졌으며 기존의 교통계획모형의 문제점을 해소하면서 특정도시 및 지역에 장.단기적 교통계획의 수립을 용이하게 할 것으로 보인다.

In this paper, We studied efficient design of wireless transmission system for unified data transmission in a subway and railway. It is increased that need of broadband multimedia service to make useful environment for user and to support the operation of railway system. High bandwidth is better if we need more services. But, high bandwidth requires more cost at tunnel of subway. More bandwidth make receive sensitivity to bad. So it need more wireless Station. We deduced best bandwidth of subway wireless transmission system reflecting the cost of installation and efficiency of system. Consequently, we decide efficient service model of broadband wireless system at a subway. Subway broadband wireless transmission system is tested in this year, and it is to be extended to province subway. Cost of subway broadband wireless transmission system is saved, because the system can be efficiently designed. Therefore, the effectiveness is expected to be very big.

Background: The reaction of nurses to the advent of artificial intelligence (AI) during the fourth industrial revolution era remains questionable. Understanding Florence Nightingale's achievements may provide valuable lessons that will be helpful to contemporary nurses. Aims: To understand Nightingale's nursing philosophy and methods and provide suggestions for future nursing practice, education, research, and health policy. Source of evidence: Literature. Discussion/Conclusion: Just as Nightingale captured the situation of her time and introduced latest scientific methods, modern nurses need to learn from Nightingale's drastic actions to meet social needs. Nursing can regain a solid humanistic foundation by returning to core values of nursing and humanities, while simultaneously adopting state-of-the-art technologies. Implications for Nursing Policy: AI-driven technologies will advance nursing services and provide greater human-centered and personalized care by eliminating iterative and labor-intensive tasks. Nursing educational policy should support the advancement of nursing curricula to develop AI competencies and specialists within the nursing field.

This paper deals with the consideration of mathematical models with regards to growth of cluster and firms by reviewing the Metcalf and Breuner's articles. prior studies have been argued the phenomenon of local industrial clusters and districts. Several concepts have been adopted to support the success of and changes to these clusters and firm growth. Through the review of two papers, evolution of both cluster and firm growth may be achieved in terms of utilizations of the different local aspects and mechanisms. This paper supports the theoretical back bone with regards to the regional cluster policy implementing in Korea for the purpose of regional developments. In particular, a mathematical model that, on a more abstract level, captures the fundamental dynamic structure of all the observed mechanisms. On the basis of this model, the emergence and evolution of local clusters can be described. Also this model has given that the knowledge sharing between firms has an important role to firms and cluster' growth.

Franchise store retailing is taking on ever greater roles in business and commerce in China. The diverse product range, small-batch order, high frequency and time-specific requirements inherent in retail logistics make it the most complicated of all categories of logistics. In franchise store retailing, expanding business scales make trans-regional development a trend. Without a well-functioning logistic system, the standardized delivery of products would be held back, impacting trans-regional development strategy and operational costs. Therefore, the efficiency of franchise store retailing largely depends on logistical efficiency. The integrated and streamlined management of franchise stores depends in large measure on their logistical centers. As such, logistical centers constitute the key link and bears on core competitiveness in franchise store retailing. This thesis begins with an analysis of the current developments and four basic logistical models of franchise store retailing in China, proceeds to summarize developmental trends as well as focal issues and proposes an efficiency enhancing plan.
