  • Finte element methods are developed for the initial distribution problems which contain the surge potential circuits of high voltage transformer windings. The initial distribution of surge voltages in transformer windings are useful to the work to a practical engineering basis. However, the conventional methods of analyzing them so far are much complicated for practical designs. In this paper, the ability to solve surge potential field problems underlies the development of descreting methods to a lodal capacitive distribution-coefficients for determing the surge voltage relationship among a set of transformer coils. A practical example-the modeling of an antioscillation shield coil winding and hisercap winding is used to illustrate and evaluate these methods.

  • Metal materials have been used in the clothing design on the spirit of ingenious experiment by fashion designers, and they have been put to practical use by several designers who work out a scheme of popular fashion merchandise. This current starting from the 1960s was weakened in the 1980s, but it was appeared with various shapes of metal materials in the 1990s due to a popularity of techno/cyber fashion. Recently, textile engineering technology causes to develop new-materials which are practical and sanitary. The development of fashionable metal materials brings about the popularization of fashion with metal materials, and it induces that mainstream of modem fashion has been changed into designers of pursuing the spirit of ingenious experiment. This study examines the formative characteristics of metal materials that are based on the spirit of ingenious experiment. As a result, it is evaluated that the formative of metal materials shown in modern fashion is futurism, visual concentration, avast-garde, resistance, precious.

  • Purpose: This study aimed to explore the experiences of hospice and palliative care (HPC) nurses at inpatient hospice centers in South Korea during the coronavirus disease 2019 pandemic. Methods: Data collection was conducted through individual interviews with 15 HPC nurses using face-to-face interviews, telephone calls, or Zoom videoconferencing. Data were analyzed using the thematic analysis method. Results: This study found that HPC nurses experienced practical and ethical dilemmas that reinforced the essential meaning and value of hospice and palliative care. The participants emphasized their practical roles related to compliance with infection prevention measures and their roles as rebuilders of hospice and palliative care. Conclusion: The findings of this study indicate that inpatient hospice centers must mitigate the practical and ethical dilemmas experienced by nurses, consider establishing explanation nursing units, and provide education to support nurses' highlighted roles during the pandemic. This study can be used to prepare inpatient hospice centers and the nurses that work there for future infectious disease outbreaks.

  • 가구디자인의 분야는 다른 제품디자인 분야와 다르게 순수 디자인영역과 함께 스튜디오작업을 병행하는 경우가 많다. 이러한 경우는 대량 생산하는 산업가구보다는 다품종 소량생산이나 맞춤형 주문가구, 혹은 부가가치를 극대화한 작품가구 등을 들 수 있으며, 이러한 작업은 주로 소규모의 공방에서 이루어진다. 이와 같은 소규모 가구 스튜디오에서의 디자인과 제작은 대량생산에 비해 형태와 조형성애서 비교적 자유로울 수 있으며 그에 대한 대표적 조형의 요소는 '곡선'이라고 볼 수 있다. 나무는 그 재료적 특성 상 원목의 곡선 카빙을 제외한 자유로운 곡선의 조형이 까다롭기 때문에 특별한 벤딩기법을 적용해야하는데 이를 위해서 본 연구에서는 베큠프레스의 벤딩기법의 효용성과 가능성을 연구하였다. 베큠프레스의 특징과 다양한 기능분석 및 이를 바탕으로 한 기법개발과 실험을 통해서, 특히 가구디자이너를 위한 소규모 스튜디오에서의 베큠프레스의 효율성과 생산성의 가치를 파악하고 보다 효과적인 벤딩의 작업성을 위해 적절한 충족조건 등을 찾아내고자 하였다.

  • Project owner, asbestos removal specialist, experts on asbestos removal work, as counter parts to be defined in the study to make out research goals have been asked with questionnaire survey and replied with 65, 275, 32 cases, respectively. And additionally, direct interview 73 sheets have been collected to find out current status of required engineers and equipments assigned and provided to the field, from them, three(3) concerned parties. Questionnaire subjects are composed of common items, reasonable unit cost, need of separate contract-awarding system, status of performing standard contract, status of providing legal engineers and equipments. Concentrated review of two~three questions by subject has been made to find out and compare idea results between three(3) concerned parties. First, legal and practical work status survey have been made to determine reasonability of introducing separate contract-awarding system, as a part of ensuring reasonable unit work cost. And then, two different status have been compared and there is introduction possibility of separate contract-awarding system, it is found out. The possibility of separate contract also has been confirmed by comparison of domestic legal grounds. Justificating grounds to introduce separate contract-awarding system have been shown. Standard contract status between asbestos removal specialists has been compared using two cases of providing removal work contract and receiving it. It is shown that case of 50 percent or less contains 38.5% when they receive contract, but only 10 percent reduction of original contract amount has been made when they provide it. It means that asbestos removal specialists do not keep occupational safety and health regulations.

  • 본 연구는 대학연계형 일학습병행제도 하에서 경영학 이론교육의 방향성을 제안하고자 한다. 사회과학으로서 경영학 교육은 본질적으로 기술습득 중심의 교육보다는 사회현상(기업경영의 현실) 속에서 올바른 의사결정을 할 수 있는 인재를 양성하는데 있다. 동시에 일학습병행제도는 현장직무를 온전히 수행하는데 도움이 되는 인재를 양성하는데 그 목적이 있다. 따라서 실무중심의 교육과 이론 중심의 교육은 유기적으로 연계되어야 하고, 그 이론 교육은 계층화되어야 한다. 또한 경영학 교육은 시의성이 보장되고 융합적 사고를 배양해야 한다. 이러한 배경을 바탕으로 본 연구는 현재 일학습병행제 틀에서 운영되고 있는 국내 대학의 경영학과의 교육과정을 검토하고 발전방향을 제시함으로써 향후 동 제도와 교육수준을 한 단계 업그레이드 시키는데 기여할 것으로 기대된다.

  • Purpose: The purpose of this study is to investigate the improvement measure of dental technicians practical examination system. Methods: The subjects in this study were 290 dental technicians who were self-written questionnaire. The results were analyzed by SPSS 16.0. The collected data was analyzed by frequency and chi-square test. Results: Dental technician practical exam feasibility of survey were largely negative views. Articulators work required in practical exam as a tool used (28.7%), electric wax carver (19.5%), heating clear (17.8%), handpiece (16.2%) had a response. Dental Technician positions in accordance with practical exam in comparison to satisfaction, the professor is satisfied, but the clinical dental technicians were generally dissatisfied (p<0.05). Conclusion: Based on the results of this study, Current is necessary to analyze the practical test. It also should be compared with foreign institutions. Long-term and short-term improvement examination system that can be applied to the improvement of the dental technician to draw practical test it is necessary to improve the system.

  • The purpose of this study is to examine an organizational performance difference by individual utilization level of the smart work. The Smart work help minimizing business process and improving organization productivity based on information technology. This new technology provides a flexible way of the task through smart-work center, videoconferencing, telecommuting, mobile(remote control) and business-only messenger. This investment changes organizational culture, institutions and behavior by new technology applying. The organization system change due to smart work has trouble between alteration preferences and existing maintains a group. In response, the organization should make investment justification of smart work for institutional and culture stabilized by a new system in organization. I set up the analytical process of four stages for empirical research. It will analyze an operation difference of the smart work between pre and post investment in the first-step analysis. The two-step analysis will conduct a text mining analysis of smart work operations. The three-step analysis will identify organization performance differences among individual levels in smart work. The four-step analysis will identify a factor difference in organizational performance by individual utilization level on smart work. According to the study, It has been revealed a difference between the pre and post investment performance on smart work. The text mining analyses many appeared an improvement opinion of organizational culture. Next, there is a difference in organization performance among utilize groups of smart work. Furthermore, the factors of organizational performance among groups appeared differently. The theoretical contribution of this study provided to expand the organizational theory of organization change and resistance. The practical implications provided to require a strong guideline an organizational culture and institution for smart work.
