Most of electric accidents are happened in the place where activities are frequent by common people who has low electric knowledge. Also, accidents are increased in the low voltage electric equipment. So, it is increased to spread the dispersion or non-utility power generation system. It means that ordinary times observation is required for electric equipments by common people. This paper is studied for the diagnosis method of electric equipment that common people can diagnose easily Voltage is generally and exactly measured in the electric and electronic field. We suggest new analysis tools using only electric voltage. It is called the Time-Energy analysis. The Time-Energy analysis is as following First, divide measured voltage waves into same parts, Second, conducted FFT(Fast Fourier Transform) transform for each divided period, Finally, each results are reassembled after graphic treatment. We compared Time-Energy analysis with discharge form by tracking tester. As the result, tracking discharge processes distinguished clearly.

A manufacturing company should produce its products and make a profit to continue its management. With the adoption of a multi-category small-volume production system, manufacturers that produce concrete pump-cine products are carrying out improvement activities to increase their market share amid the business-to-customer business environment. However, the slump in the construction investment environment has led to a decline in sales of concrete pump trucks. The purpose of holding inventory is to prevent loss of sales opportunities with the rate of change in the sales plan, and reducing the rate of change in the product can reduce unnecessary inventory and, in order to realize this, the goal of reducing inventory can be achieved by reviewing the parts that can be designed for common use. Therefore, to reduce the inventory of concrete pump trucks, semi-finished publicization design is necessary. According to the analysis, the frame assembly process of the 32M model is common. Production capacity can be secured without loss of sales opportunity.

Background: Common questions about shoulder arthroplasty (SA) searched online by patients and the quality of this content are unknown. The purpose of this study is to uncover questions SA patients search online and determine types and quality of webpages encountered. Methods: The "People also ask" section of Google Search was queried to return 900 questions and associated webpages for general, anatomic, and reverse SA. Questions and webpages were categorized using the Rothwell classification of questions and assessed for quality using the Journal of the American Medical Association (JAMA) benchmark criteria. Results: According to Rothwell classification, the composition of questions was fact (54.0%), value (24.7%), and policy (21.3%). The most common webpage categories were medical practice (24.6%), academic (23.2%), and medical information sites (14.4%). Journal articles represented 8.9% of results. The average JAMA score for all webpages was 1.69. Journals had the highest average JAMA score (3.91), while medical practice sites had the lowest (0.89). The most common question was, "How long does it take to recover from shoulder replacement?" Conclusions: The most common questions SA patients ask online involve specific postoperative activities and the timeline of recovery. Most information is from low-quality, non-peer-reviewed websites, highlighting the need for improvement in online resources. By understanding the questions patients are asking online, surgeons can tailor preoperative education to common patient concerns and improve postoperative outcomes. Level of evidence: IV.

The purpose of this study is to verify the result of the previous studies and to clarify the types and activation factors of maintenance activities of the naturally favorable water space through the participation of residents in rural areas, through a further survey of the area proposed as a program in the existing study review and previous study related to the participation of residents. The survey was conducted through the survey of 1,242 households and 1,335 persons intended for Japanese rural areas. The study result is summarized as follows. The types of the maintenance activities in the areas intended for the survey have been classified into 'rural type' and 'combination type' through the analysis results by the references like the comparison analysis, job percentage and main utilization purpose of facilities for each type of maintenance and operation activities. In case of the 'rural type' area, residents were doing maintenance activities centered on the group activities rather than personal maintenance activities. Also, the activities of maintenance & operation group members were more active than non-members, and the water-friendly utilization to the facilities was not directly affecting the maintenance activities of residents. In case of the 'combinational type' area, there was no common characteristic according to each area, and the participation percentage in the maintenance activities was low compared with the 'rural type' area. According to the analysis result based on the participation degree of personal maintenance activities, the repair of facilities as a naturally favorable water space, implementation of projects reflecting the opinions of residents, educational programs conducted in order to motivate the participation of residents, etc. have been analyzed as the factors affecting the activation of maintenance activities of residents. Through the above results, for continuous maintenance activities to be made with residents as a main body in the future, it is necessary to support maintenance groups on an administrative level and procure experts for the production and operation of programs that can increase the participation percentage of residents.

The occupational health nursing guideline for primary care was developed by the Korean Academic Society of occupational health nursing and the organization for occupational health nurses (currently known as the Korean Association of Occupational Health Nurses) in 1993. Since then, there have been many changes in the health care environment and job performance of occupational health nurses. Appropriate revisions are necessary of the guidelinea based on this background. The purpose of this study was to describe the use of the occupational health nursing guideline for primary care and to analyze the characteristics of primary care activities by occupational health nurses. The questionnaire was mailed to 150 occupational health nurses(OHNs) with the response rate of 64%. The results can be summarized as follows; 1. 65.6% of OHNs have been using the guideline for primary care and 75.9% of them agreed that the guideline was be helpful for their job. 2. Common symptom care, emergency care and chronic illness care were more frequently implemented than occupational disease care by OHNs. In manufacturing industries, emergency care was more frequently implemented than chronic illness care in contrast to the service industries. 3. Most frequent common symptoms treated by OHNs were indigestion, diarrhea, abdominal pain, headache, and coughing. In the case of chronic illness, OHNs more frequently treated diseases of the gastro-intestinal system, skin and sensory organs, and the respiratory system. Emergency care for bruises, burn, and abrasions was more frequently provided. VDT syndrome was the most common occupational disease cared by OHNs in manufacturing and service industries. 4. OHNs prescribed the medicine for external application more frequently than internal medicine. Remedy for colds, analgesics, vitamins, and digestives were more frequently used. From these results, we suggest that the guideline should be revised to emphasize the activities consisting problem finding such as health assessment, physical examinations, monitoring and screening, and to renew the drug list in the range of over- the counter medication (OTC). In the future, the guideline will include the strategies for the role as the case manager.

이 연구는 마을 주민이 마을숲 보전 사업에 참여할 가능성에 영향을 미치는 인자를 분석하는 데 목적이 있다. 성별, 연령, 출신지, 부의 수준, 마을숲 이용 빈도, 마을조직 대표 경험과 같은 주민들의 사회경제적 특성이 마을숲 보전 사업 참여가능성에 영향을 줄 것이라고 예상하였다. 설문조사를 통해 마을숲이 존재하는 두 마을에서 각각 52명, 41명의 응답을 얻을 수 있었으며, 순서화 로짓 모형을 이용하여 수집된 자료를 분석하였다. A마을에서는 마을숲 이용 빈도가 높은 사람일수록 마을숲 보전 사업 참여가능성이 높게 나타났으며, B마을에서는 그 마을에서 태어나고 마을조직 대표 경험이 있는 사람일수록 마을숲 보전 사업 참여가능성이 높게 나타났다. 주민들의 마을숲 보전 사업 참여가능성에 영향을 미치는 요인이 마을별로 다르게 나타난 이유는 마을숲 소유권으로 인한 마을 주민들의 마을숲 이용 현황과 마을숲 문화의 유무에 따라 마을숲 가치를 이해하고 있는 주민의 비율이 서로 달랐기 때문으로 판단된다. 따라서 마을숲 보전 사업에 주민들의 참여를 유도하기 위해서는 마을숲의 이용권한을 지역 주민들에게 부여하고, 마을숲을 활용한 문화행사나 교육사업 등을 통하여 마을숲에 대한 주민들의 이해도를 높이는 것이 필요하다.

Asia-Pacific Space Cooperation Organization (APSCO) is the only intergovernmental space cooperation organization in Asia. Since its establishment to date, eight countries have signed the convention and become member states. South Korea participated actively in the preparatory phase of creating the organization, and one conference organized by AP-MCSTA which is the predecessor of APSCO was held in South Korea. However, after the APSCO Convention was opened for signature in 2005 to date, South Korea does not ratify the Convention and become a member. The rapid development of space commercialization and privatization, as well as the fastest growing commercial space market in Asia, provides opportunities for Asian countries to cooperate with each other in relevant space fields. And to participate in the existing cooperation framework (e.g., the APSCO) by the Asian space countries (e.g., South Korea) could be a proper choice. Even if the essential cooperation in particular space fields is challenging, joint space programs among different Asian countries for dealing with the common events can be initiated at the first steps. Since APSCO has learned the successful legal arrangements from ESA, the legal measures established by its Convention are believed to be qualified to ensure the achievement of benefits of different member states. For example, the regulation of the "fair return" principle confirms that the return of interests from the relevant programs is in proportion to the member's investment in the programs. Moreover, the distinguish of basic and optional activities intends to authorize the freedom of the members to choose programs to participate. And for the voting procedure, the acceptance of the "consensus" by the Council is in favor of protecting the member's interest when making decisions. However, political factors that are potential to block the participation of South Korea in APSCO are difficult to be ignored. A recent event is an announcement of deploying THAAD by South Korea, which causes tension between South Korea and China. The cooperation between these two states in space activities will be influenced. A long-standing barrier is that China acts as a non-member of the main international export control mechanism, i.e., the MTCR. The U.S takes this fact as the main reason to prevent South Korea to cooperate with China in developing space programs. Although the political factors that will block the participation of South Korea in APSCO are not easy to removed shortly, legal measures can be taken to reduce the political influence. More specifically, APSCO is recommended to ensure the achievement of commercial interests of different cooperation programs by regulating precisely the implementation of the "fair return" principle. Furthermore, APSCO is also suggested to contribute to managing the common regional events by sharing satellite data. And it is anticipated that these measures can effectively response the requirements of the rapid development of space commercialization and the increasing common needs of Asia, thereby to provide a platform for the further cooperation. In addition, in order to directly reduce the political influence, two legal measures are necessary to be taken: Firstly, to clarify the rights and responsibilities of the host state (i.e., China) as providing assistance, coordination and services to the management of the Organization to release the worries of the other member states that the host state will control the Organization's activities. And secondly, to illustrate that the cooperation in APSCO is for the non-military purpose (a narrow sense of "peaceful purpose") to reduce the political concerns. Regional cooperation in Asia regarding space affairs is considered to be a general trend in the future, so if the participation of South Korea in APSCO can be finally proved to be feasible, there will be an opportunity to discuss the creation of a comprehensive institutionalized framework for space cooperation in Asia.
