Although the corporate governance plays a crucial role in protecting shareholder wealth, the effect of corporate governance on cost of debt is unclear. On one hand, the corporate governance reduces asymmetric information between corporate and external investor including debtholder leading to a decreasing in cost of debt financing. On the other hand, bondholders require higher rate of return for an improvement corporate governance. Hence, this study aims to investigate the relationship between the mechanism to improve corporate governance namely board effectiveness and the cost of debt in an emerging market. As we aim to explore the relationship between cost of debt and board effectiveness, we select corporation in Thailand as our sample because the businesses in Thailand are major debt-financing. Hence, our sample include listed firm in Stock Exchange of Thailand between 2007 and 2016. Our main findings support the sub-optimal investment hypothesis in that improved board effectiveness is associated with higher cost of borrowing. In addition, we find that the number of board member-board size, the number of board meeting, and the percentage of non-executive on audit committee play are positively associated with the cost of debt financing. Furthermore, we perform two-stage-least square (2SLS) to ensure that our results are far from endogeneity issue.

In general, under the concept of unit load, Automated Storage/Retrieval Systems (AS/RS) have the rack of equal sized cells. However, they are inadequate and inefficient meeting the various sizes of customers' demands in today's business environment. Higher utilization and flexibility of warehouse storage can be achieved by using AS/RS with tile rack of modularized cell. In this paper, the model of AS/RS with the rack of modularized cell is proposed, and the effectiveness of proposed model is presented by way of numerical examples. The model developed in this research, as one type of AS/RS that is more flexible to the size and has higher space utilization than those of existing rack structure, could every useful for the storage of heterogeneous unit load sizes.

Objective : This study aimed to investigate the level of friendship perceived by hospital staffs in korean medicine hospitals in Gwangju and relationship between friendship and organizational effectiveness. Method : The subject were 134 hospital staffs in 5 different hospitals in Gwangju. The questionnaire used in this study contained 44 questions about workplace friendship (15 questions), organizational effectiveness (16 questions), social demographic characteristics (8 questions) and others (5 questions). Results : Young woman in their 20s and 30s were major participants (69person, 52.7%), nursing and administrative department(72person, 55%) were dominant division, the person those who have less than 1 year current workplace career(69person, 52.7%) were major group in this study. Participants responded about barriers of friendship at workplace were lack of opportunities for formal or informal meeting and lack of hospital's interest and supporting about human relations among employees at workplace. Both friendship level with superior and friendship level with subordinate were lower than friendship level with colleague. (p=.000) Participants who have higher workplace friendship level, were also higher level at job satisfaction, organizational commitment and lower level at turnover intention, job stress. Especially friendship level with superior had biggest relationship with variables of organizational effectiveness. Conclusion : Participants showed close relationship with friendship degree and organizational effectiveness. We suggest that the CEOs of korean medicine hospital would make their effort to improve friendship level of workers for the rise of organizational effectiveness.

Due to the rapid growth of domestic and overseas airline markets, the demand for airline pilots has also been growing fast. Meeting such a market needs, central government, Ministry of Land and Transportation has set up civil airline pilot training center at Ulgin airport to train and provide the market with commercial airline pilots. Not only central government but universities in Korea also have tried to train pilots by operating flight training academies. Even though there are more than a dozen of flight training centers including colleges and private academies, there have been less efforts to measure and evaluate the effectiveness of the flight training school's curriculums compared to other scholar majors in a university. Therefore this paper tried to evaluate the educational effectiveness of the curriculums using the Kirk-Patrick measurement model, which has been regarded as one of the most popular and accurate measurement tool for an empirical research in social science. According to the empirical research, it was found out the inter-personal relationship between an instructor pilot and flight trainee was perceived as the most important factor to have an impact on learning abilities and student's behaviors.

This study explored the sandplay therapy case of a middle-aged woman having difficulty with interpersonal relationships and wanting to increase her self-identity. The goal of the therapy was to change her relationships with others by self-examination and becoming conscious of her negative animus and femininity in a free and protected space provided by sandplay therapy. Forty-five therapy sessions were held. The client exhibited her lonesomeness and fantasies by making sandtrays of a house she would like to live in, a park she would like to relax at and dreams she would like to fulfill in the initial phase of therapy (1~8, Who am I?). In the intermediate phase of therapy (9~33, Meeting myself), she displayed scenes of her negative self and breaking away from her negative self by making sandtrays of shadows, deaths, creations, a soaring scene and a disappearing alligator. In the final phase of therapy (34~45, Discovery of the real Self), she showed scenes of her meeting a positive self by making sandtrays of hope, coexistence, start, harmony and community. This study showed the effectiveness of sandplay therapy since the client' relationships with others were improved through her self-awareness by sandplay therapy in the free and protected space.

Among the semiconductor If-chips, unlike memory chips, a majority of Application Specific IC(ASIC) products are produced by customer orders, and meeting the customer specified due date is a critical issue for the case. However, to the one who understands the nature of semiconductor manufacturing, it does not take much effort to realize the difficulty of meeting the given specific production due dates. Due to its multi-layered feature of products, to be completed, a semiconductor product(called device) enters into the fabrication manufacturing process(FAB) repeatedly as many times as the number of the product specified layers, and fabrication processes of individual layers are composed with similar but not identical unit processes. The unit process called photo-lithography is the only process where every layer must pass through. This re-entrant feature of FAB makes predicting and planning of due date of an ordered batch of devices difficult. Parallel machines problem in the photo process, which is bottleneck process, is solved with restricted roll out algorithm. Roll out algorithm is a method of solving the problem by embedding it within a dynamic programming framework. Restricted roll out algorithm Is roll out algorithm that restricted alternative states to decrease the solving time and improve the result. Results of simulation test in condition as same as real FAB facilities show the effectiveness of the developed algorithm.

One of the most important issues in a small and medium sized enterprise (SME) is to identify how to apply IT to the organization so that it maximizes the effectiveness of IT. In general, a large company mainly plans to adopt, implement, and stimulate a new IT in a viewpoint of advanced IT system's capability for maximizing the effectiveness of IT. However, SME requires a totally different approach since SME's situation is different from a large enterprise's one. In this study, we investigate several factors that have an influence on the successful IT adoption and implementation of a SME through the case of Hwacheon. We also find out that CEO's support, CEO-initiating strategic meeting, IT development ability, and organizational compatibility in the introduction stage of IT are relatively more important than those in the implementation stage of IT, whereas IT flexibility, system quality, training and support, overcoming organizational resistance and performance improvement in the implementation stage of IT play critical roles in the IS success. Our results show that the advance of IT may not guarantee the success of IT implementation.

In order to present the enhancement direction for the military administrative facilities, that can satisfy the user demands and achieve cost-effectiveness the goal of public projects, this research analyzes the features of functional spaces using Analytical Hierarchy Process(AHP). Basically, the scope is selected to four facilities commander office, private office, public office, and meeting room, because they have an effect on military administrative facilities. Since the space is established by a combination of their own functions, this research begins with an analysis of functional spaces of military administrative facilities, which is verified through literature review and interview with expert. Thereafter, an AHP survey is conducted to military personnel to analyze the priority of functional spaces and to re-classify the functional spaces of each Military administrative facilities. Resultingly, the difference of functional spaces preference according to ranks and facility type are identified. Even though the same military facilities, it means that user satisfaction is different. Therefore, user satisfaction should be considered for each facility at the construction plan. It can minimize overlapped and unused spaces, which can help ensure cost-effectiveness. Consequently, this research suggested the methodology and the process that can take user satisfaction and can support the enhancement of military facilities standards.
