The purpose of this review is to name and describe the important factors of musculoskeletal strain originating from pushing and pulling tasks such as cart handling that are commonly found in industrial contexts. A literature database search was performed using the research platform Web of Science. For a study to be included in this review differences in measured or calculated strain had to be investigated with regard to: (1) cart weight/ load; (2) handle position and design; (3) exerted forces; (4) handling task (push and pull); or (5) task experience. Thirteen studies met the inclusion criteria and proved to be of adequate methodological quality by the standards of the Alberta Heritage Foundation for Medical Research. External load or cart weight proved to be the most influential factor of strain. The ideal handle positions ranged from hip to shoulder height and were dependent on the strain factor that was focused on as well as the handling task. Furthermore, task experience and subsequently handling technique were also key to reducing strain. Workplace settings that regularly involve pushing and pulling should be checked for potential improvements with regards to lower weight of the loaded handling device, handle design, and good practice guidelines to further reduce musculoskeletal disease prevalence.

본 연구는 우리나라 都市內 小規模 工業의 立地決定要因을 규명하기 위한 行態的 硏究의 일환으로, 부산시의 소규모 工業經營者들이 都市內部에 공장임지를 결정함에 있어서 실제로 고려하눈 立地要因이 무엇이며, 또한 그 요인은 기업특성, 경영자특성, 입지장소의 용도지역상 성격에 따라 차이가 있는가를 밝히는 데 목적이 있다. 이를 위해 부산시내 소규모 공업경영자들을 대상으로 설문지에 의한 면접조사를 실시하였다. 그 결과, 소규모 공업의 입지결정에 영향을 미치는 요인이 기업의 특성은 물론 경영자 및 용도지역의 특성에 따라 많은 차이가 있음을 확인하였다. 이는 도시내부의 비공업지역에 소규모 공장이 입지함에 있어서 토지를 비롯한 경제적 요인과 더불어 비경제적 요인이 상당한 영향을 미치고 있음은 입지정책에 시사하는 바가 크다고 볼 수 있다.

MICE (Meetings, Incentive travels, Conventions, and Exhibitions) segment is one of the fastest growing segments of the tourism industry today. Especially, the government promotes the convention business as a strategic industry given its growing importance as a high value-added export. The push-pull factor conceptual frameworks were used to identify motives that lead firms to attend conventions. Furthermore, the authors assess firms' service quality, preference, reliability, and positional advantage of Korea Electronics Show(KES). Using data from a number of Korean trading firms, the authors find considerable results and conclude by discussing recommendation for the convention industry.

Objectives: To assess the risk of pushing or pulling the yarn-carrying cart, the survey was performed in some fiber manufacturing factories. Methods: We selected 6 fiber-twisting factories which agreed to in-site survey of their workplace. To measure both initial and sustained forces of the push-pull tasks, Chatillon CSD500 dynamometer(2004, Ametek, USA) was used. The mean of 3 tests for the same cart was adopted as the measured forces. Height and width of cart, weight of spooled yarns, and distance of movement were also measured. Inspection of cart wheel, moving path, and the actual hand position while moving was done. Results: More than one pushing or pulling task exceeded the push-pull force limits of design goal in 5 factories. Though the cart was not loaded the heaviest weight in the factory, the measured push or pull force exceeded the limits several times. A few cart wheels were worn out and tangled with pieces of yarn. It was also observed some holes in the moving path. Conclusions: While the push-pull task is not included in the 11 scopes of over-burdened work notified by Korean government, it should be recognized as risk factor of work-related musculoskeletal disorders. The maintenance work such as regular change and frequent cleaning of cart wheel, the use of fitting wheel, and flattening of bumpy floor through the moving path should be advised importantly in the worksite management of work-related musculoskeletal disorders.

We suggest that the core factor which can be established successfully pushing ahead with domestic load management program is finding and keeping management of controllable load resources. We know that load management is mostly the maximum demand power management and participation of DLC program. This paper suggests the way coping with load management suggesting model which air conditioning and heating load facilities are applied to DU program.

The bushing for high voltage and large and power should endure weight of itself and force of pushing from contact with circuit breaker. Like this, epoxy mold bushing has to be strong without fault. However, the external circumstances and internal factors was caused by partial discharge, flashover and dielectric breakdown. Therefore, to remove external factor of defect and to prevent the internal cracks and cavity generated from the contraction on interface of Cu-Epoxy, we should form semi-conductive layer on Cu bar by carbon. Then, the PD properties and the insulation qualities of epoxy mold type bushing was able to improved by roles of cushions for the direction of diameter and by effects fo natural sliding like as separated from conductor for the direction of length. So, in this work, we could prove the method of semi-conductive layer in making the long conductor.

Leisure motivation is an important concept in the study of leisure behavior. The purpose of this study was to examine visitors' motivations for hot spring resorts in Korea. The data were collected by questionnaires survey in three hot spring resorts in 1994:Suanbo, Paikam, and Chuksan. The findings of this study are summarized as follows: The eight motivation factors extracted by factor analysis such as; 1)"intellectual needs", 2)'escaping everyday life', 3)'closing nature', 4)'recognition or status', 5)'interaction with others', 6)'health', 7)'family vacation', 8)'hot spring bathing'. The three resorts showed significant deferences in the motivation of visitors. Visitors of Suanbo have high motivation for 'intellectual needs', 'interaction with others', and 'thealth', and visitors of Chuksan for 'closing nature', 'family vacation', and 'hot spring bathing'. This study has proved first, psychological(pushing) factors are more important than pulling factors of resorts, second, in pulling factors, natural sceneries were more important than medicinal properties of the hot springs. And this study found several important implications for predicting visitors' demand in hot spring resorts.

Online game business has emerged as the most lucrative entertainment industry, with over 10 million players in South Korea and over 30 million in Japan in 2005. The popularity of online games can be attributed to the availability of broadband network, pushing online games into the mainstream entertainment culture. The age distribution of online game players is expanding and a variety of new games are under development to target certain age groups. While the interactive entertainment market continues to expand, with many new online game publishers entering the Japan, relatively little is known about which factors influence online game players' behavioral intentions to play continuously in this area. This study investigates major factors which influence the acceptance of online game services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This paper extended the Davis' TAM model by including the flow concept as another major factor toward the intention to play online game. Based on data collected from online questionnaire survey, we show that the proposed model provides an adequate fit to the data, and that the flow experience is another important factor influencing the intention to play online game, as well as the perceived ease of use.

The purpose of this research was to investigate the differences in the ski carving turn motion according to level of expertise. The posture and movement of 6 skiers nearby the fall-line was evaluated with a biomechanical approach focusing the rotational mechanics. The slope was at an angle of $9^{\circ}$ and the following variables were measured and calculated: tangential velocity, change of COM height after passing fall-line, width between feet, angle between upper body and thigh, trunk angle, average radius of curvature and average centripetal force. The expert skiers minimized their center of mass height movement and maintained the width of between their feet after the passing the fall-line in comparison with the beginners and intermediate skiers. The experts restrained themselves from pushing their upper body downward after the turn to maximize the centripetal force. The experts in comparison with the beginners and intermediate skiers during the turn didn't have to reduce their radius of curvature to maintain a high centripetal force. It was concluded, that the most important factor affecting the centripetal force, was for the beginners and intermediate skiers, to minimize their movement while using the appropriate amount of edging.
