The systematic management of technology infrastructure increasingly becomes critical as it represents the driving power for creating competitive advantage of nations and enterprises. In this sense, public facility and equipment, which is one major asset of technology infrastructure, should be managed effectively, systematically and efficiently to increase its overall equipment effectiveness. However, the manual and off-line communication was the unique way to communicate between the suppliers who provide facilities in the public sector and the customers who utilize the facilities in the industrial sector. This communication way caused invisibility of available usage time and increase of idle time, thereby decreasing the equipment effectiveness. This paper presents an web-based scheduling system that enables real-time collaboration and information sharing for increasing the equipment effectiveness. The designed system performs scheduling, facility management, order management and customer relationship management in an on-line platform, and carries out the processing and storing of relevant information in an integrated database. The paper includes a development approach to identify business process models and standardized system models by using object-modeling technique. The deliverable of the present work will contribute to increasing the equipment effectiveness by enhancing visibility, transparency and predictability by means of the integration with a legacy Enterprise Resource Planning.

2016년 12월 9일 국회가 박근혜 대통령의 탄핵소추안 결의는 박근혜 대통 령과 집권당인 새누리당의 친박(親朴) 대 비박(非朴) 간의 제20대 총선 공천 파동에서 비롯됐음을 알 수 있다. 그러므로 이 논문은 제20대 총선에서의 여․ 야 정당의 공천파동 행태가 국민들의 표심에 어떤 영향을 미쳤는가를 연구의 초점으로 한다. 총선을 앞두고 표출된 여․야 당의 공천파동은 제19대 대선 승리를 위한 전초전으로 계파간의 이전투구 그 자체였다. 첫째, 여․야 각 정당의 공천파행이 박근혜 대통령은 물론 여․야 당 대표나 지도부 및 공천심사위원장 등을 중심으로 어떻게 펼쳐졌는지 살펴보고자 한다. 둘째, 이러한 공천파동의 행태가 대선을 앞둔 시점에서 각 정당의 대선후보 구도에 어떤 변화를 초래할 지를 살펴보는 것이다. 셋째, 선거 전후에서 나타났듯이 더불어민주당과 국민 의당 간 야당 분열과 호남에서의 주도권 문제에 어떠한 인과관계가 있는지를 다루고자 한다. 이 논문의 분석 결과, 제20대 총선은 집권 새누리당의 과반수 의석 획득에 실패하고 야당이 승리함으로써 여소야대(與小野大)를 형성하였다. 야권이 분열한 상황에서도 박근혜 대통령과 새누리당이 대패한 이유는 무엇보다 야권 분열로 인해 총선 승리를 예단한 친박과 비박계의 공천 내홍에 근본 원인에 있다. 그에 따른 책임론이 '과거권력'이 돼 버린 박근혜 대통령을 향해 제기될 공산이 크고, 상대적으로 야당에 의한 미래권력의 등장이 앞당겨 질 가능성을 열어둔 것이다. 야당의 경우 전통적 야당 텃밭인 호남 쟁탈전은 ‘문재인’과 ‘안철수’라는 두 대권주자의 명운이 걸린 사안인 점만은 분명하다.

This study aims to investigate effects of the length of the buoy and sand bag line on the loss of webfoot octopus pot. A numerical modeling and simulation was carried out to analyze the process that the pot gear affected by wave using the mass spring model. Through the simulation, tensions of sand bag line under various condition were investigated by length of buoy and sand bag line. The drag force and coefficient k of an artificial shell used in the webfoot octopus pot was obtained from an experiment in a circular water channel, and the coefficient k was applied to the simulation. To verify the accuracy of the simulation model, a simple test was conducted into measuring a rope tension of a hanging shell under flow. Then, the test result was compared with the simulation. The lengths of the buoy line in the simulation were 1.12, 1.41, 1.80, 2.23, 2.69, and 3.17 times of water depth. The lengths of sand bag line were 10, 20, 30, and 40 meters, and conditions of water depth were 8, 15, 22 meters. 4 meter height and 8 second period of wave were applied to all simulations. As a results, the tension of the sand bag line was decreased as the buoy and sand bag line were increased. The minimum tension of the sand bag line was appeared in conditions that the length of the buoy line is twice of water depth and the sand bag line length is over 40 meters (except in case of depth 8 meters.).

The efficiency of the purchasing and procurement logistics is important in automotive industry. The rationalization of production system is directly impact on productivity and quality. For this reason importance of logistics is high. Despite we are continuously making effort, our country are still below the level than developed country on logistics efficiency. Rising labor costs is an important factor in increasing logistics costs. So workforce reduction in logistics department is a large part. We deal with A-company inbound logistics, especially procurement logistics in automotive logistics as research object. So in this study we do research on work load balance about workers. We do research on 1,475 kinds of components in procurement process. We applied work load balance algorithm on chassis, final, sequence, trim warehouses workers. According to number of workers and average M/H, algorithm is applied in two ways. After applied work load balance algorithm we reduced numbers of workers from 28 to 20 and improved worker load balance rate from 47.1% to 93.7%

The purpose of this study was to investigate the effects of power blog self- presentation and on-line shopping mall reviews on the word of mouth (WOM) effect and apparel purchasing behavior. Consumers living in Seoul and Gyeonggi received questionnaires. There were 303 usable forms that could be analyzed by descriptive statistics, factor analysis, Cronbach’s alpha, and regression analysis. The results were as follows: There was a significant effect of power blog self-presentation such as interactivity, media effect, and business intention on information acceptance through WOM. Power blog self-presentation, such as interactivity and business intention, affect information delivery by WOM significantly. There was a significant effect of review consideration, such as agreement, usefulness, enjoyment, and purity, on information acceptance of WOM. Reviews describing enjoyment, purity, and usefulness affect information delivery of WOM significantly. Business intention, media effect, and purity directly affect apparel-purchasing behavior, and affect the WOM effect as a mediator variable and then purchasing behavior. Whereas, interactivity, overstatement, and enjoyment affect the WOM effect as a mediator variable, and then affect overall purchasing behavior. Therefore, fashion firms consider active interaction with power blog visitors and promote the way of enjoying with fun through review of apparel on-line shopping mall when they try to implement viral marketing with WOM effect.

Korean automobile industrial is in a difficult situation because of more competitive global market and lower demand. Therefore, domestic as well as global automobile manufacturers are making greater efforts in cost reduction to strengthen the competitiveness. According to statistical data, logistics cost in domestic manufacturers is higher than advanced countries. In this study, we developed program to effectively manage standard time of procurement logistics, and confirm based on A-automobile factory data. For the purpose, we develop the system which is possible to manage standard time as well as calculate man-hour. Program is not just for calculating and managing standard man-hour, scenarios analysis function will be added to calculate benefit while introduce logistics automated equipment. In this study we propose scenario using AGV instead of electric motor while move component. In the scenario analysis, job constitution is changed，and then we use system to compare the result. We can confirm standard man-hour is reduced from 22.3M/H to 14.3M/H. In future research, it is necessary scenario analysis function, and develop algorithm with realistic constraint condition.

This is to develop a micro water turbine which makes some power from just a fluid velocity in the water pipe. While power is produced from impulsive force which generated by a high head in the case of existing water turbine, this is to produce a power from rotating force of helical turbine which rotated by fluid velocity in the water pipe. Some results of analysis fluid pattern at turbine blade for design shows that bubble is generated from turbulence surrounding blade and pulsatory motion generated as fluid being blocked and opened by blade due to turbine structure. This two phenomena cause to lower power production efficiency and shorten turbine durability. So this is studied to minimize bubble generation and pulsation for optimizing design of turbine blade. Therefore it is determined that the number of blade is three, geometric form of blade is NACA 4420 and angle of blade is 30 degree. An experiment equipment of water turbine is manufactured on the base of these factors(NACA 4420, angle 30。). It is obtained that power production of turbine increases in proportion to velocity which is changed from 1.7 m/sec to 3.5 m/sec. When fluid velocity is 1.7m/sec the power production of turbine is 355W. Power production increase continuously as increasing the fluid velocity and power is 2kW on 3m/sec of fluid velocity.

There has been an increasing demand for effective on-line English teacher education programs due to the advantages including cost efficiency and easy access. Despite the provision of a variety of on-line English teacher education programs, only a small number of studies on on-line in-service education program for English teachers have been carried out. This study aims to provide a basic model of on-line in-service English language teacher education based on the critical awareness. To do this, previous studies on on-line in-service English language teacher education in Korea and abroad were critically reviewed and key issues were derived. They are top-down approach to on-line teacher education curriculum development, unsustainability of teacher education, disconnection of teacher education to practice, insufficient establishment of community of practice, and deficiency of reflection on teaching practice. Three on-line English teacher education programs were selected and evaluated by using these key issues. It is suggested that bottom-up approach to curriculum development, establishment of community of practice for the sustainability of teacher education, and reflective learning for connecting teacher education to real classroom practice be included as key components for effective on-line teacher education.

The objective of this study is to investigate the effect of ELF (Extremely Low Frequency) exposure on the health of elementary school students. A total of 103 students 12~13 years old were chosen for the study. The experimental group consisted of 56 students who went to school near an overhead powerline. The ELF exposure and environmental hazard factors were evaluated during a 24-hour exposure period. The body and dwelling characteristics of the students as well as disease occurrence related to the respiratory system and allergies were investigated through a questionnaire. The brain wave and electrocardiogram were also inspected. The exposure of the group exposed while at a school located near a powerline was 6.8 mG (p<0.01). Based on the questionnaire results, neither the body or dwelling characteristics of the two groups were affected by the ELF emitted from powerline. There was no significant difference between the two groups in relation to the rate of occurrence of respiratory diseases such as wheezing, asthma and bronchitis. Although brain waves of the group exposed to ELF were lower than that of the group not exposed to it in terms of absolute power of gamma and beta, there is no significant difference between the health status of the two groups. According to our study, school students who lived near a power line were exposed to higher ELF levels than those away from a power line. The two groups have significant differences inBrain wave and ECG, but this change doesn't mean there is a difference in health status. Finally, our study has a limitation in terms of the number of study subjects and the restricted area examined.

Recently, some fashion retailers have initiated sustainable actions in the form of corporate social responsibility (CSR) activities to address consumers’ social concerns. This study intends to combine the concept of CSR motivation attributions with brand extension literature in order to examine how consumers’ trust of a parent brand affects their CSR motivation attributions and ultimately their attitudes towards parent-brand CSR activities and sustainable extension lines. A self-administered online survey was conducted using scenarios describing a fast fashion retailer introducing a sustainable line. Data from 303 female U.S. consumers, aged between 18 and 34 years, were used for the statistical analysis. Data analyses were conducted using SPSS 21.0 for descriptive analysis, exploratory factor analysis, and regression analysis. The results revealed that all hypotheses were supported. The findings show that consumers’ trust of a parent brand has an indirect impact on positive attitudes towards the parent brand’s CSR activities as well as the sustainable extension product line, mediating positive evaluations of the brand’s social CSR motivations. In addition, this study suggests consumers’ prior trust of the parent brand is a variable that affects consumers’ evaluation of CSR motivation sincerity. Marketing suggestions and thoughts based on the findings of this study were provided.

PURPOSES: This study suggests the application of glow line marking technology for reducing traffic accidents at nighttime. METHODS: In this study, using a statistical analysis, we analyzed the characteristics of traffic accidents occurring at nighttime. Next, the strength, weakness, opportunity, and threat (SWOT) factors were derived based on a current-status analysis of glow line marking technology and road environments. An SO strategy, ST strategy, WO strategy, and WT strategy were established in accordance with the four SWOT factors. RESULTS : This study suggests that the following strategies should be promoted to apply glow line marking technology to a road environment: 1) an activation strategy for the technological development of glow line markings for a new paradigm in reducing traffic accidents, 2) a benefit enhancement strategy applying glow line marking technology in places where nighttime traffic accidents frequently occur, 3) a strategy for the expansion of glow line marking by replacing streetlights, and 4) a strategy for enhancing road applications through the development of various line marking methods in consideration of both performance and costs. CONCLUSIONS : The application of glow line markings in a road environment can contribute to a reduction of traffic accidents at nighttime, and aid energy savings from the replacement of streetlights.

Shikonin, a major ingredient in the traditional Chinese herb Lithospermumerythrorhizon, exhibits multiple biological functions including antimicrobial, anti-inflammatory, and antitumor effects. It has recently been reported that shikonin displays antitumor properties in many cancers. This study was aimed to investigate whether shikonin could inhibit oral squamous carcinoma cell (OSCC) growth via mechanisms of apoptosis and cell cycle arrest. The effects of shikonin on the viability and growth of OSCC cell line, SCC25 cells were assessed by MTT assay and clonogenic assays, respectively. Hoechst staining and DNA electrophoresis indicated that the shikonin-treated SCC25 cells were undergoing apoptosis. Western blotting, immunocytochemistry, confocal microscopy, flow cytometry, MMP activity, and proteasome activity also supported the finding that shikonin induces apoptosis. Shikonin treatment of SCC25 cells resulted in a time- and dose-dependent decrease in cell viability, inhibition of cell growth, and increase in apoptotic cell death. The treated SCC25 cells showed several lines of apoptotic manifestation as follows: nuclear condensation; DNA fragmentation; reduced MMP and proteasome activity; decrease in DNA contents; release of cytochrome c into cytosol; translocation of AIF and DFF40 (CAD) onto the nuclei; a significant shift in Bax/Bcl-2 ratio; and activation of caspase-9, -7, -6, and -3, as well as PARP, lamin A/C, and DFF45 (ICAD). Shikonin treatment also resulted in down-regulation of the G1 cell cycle-related proteins and up-regulation of p27KIP1. Taken together, our present findings demonstrate that shikonin strongly inhibits cell proliferation by modulating the expression of the G1 cell cycle-related proteins, and that it induces apoptosis via the proteasome, mitochondria, and caspase cascades in SCC25 cells.
