The purpose of this research is to review testing principle, testing design and experimental results of the four dynamic moisture movement testers. The research analyzes Moisture Manager Tester (MMT), Alambeta Instrument, Dynamic Surface Moisture Movement Tester, and Gravimetric Absorbent Testing Method based on American Society for Testing and Material (ASTM) E 96 which is an international standard testing method. Although many of researches use ASTM E 96 to measure moisture movement on a fabric, it has several weaknesses, such as long experimental time and a physical change of sample by a holder of the frame. Hence, lots of researchers have studied and developed the new measurement systems measuring moisture management on a fabric or garment and ultimately mimic heat energy and perspiration created by the human body. These moisture management systems use a variety of parameters, such as electricity, color, and sensor to measure their movement in the fabric. Through comparison with the existing tester (ASTM E 96), the research recognizes the strength and weakness in the dynamic moisture movement testers.

Construction delay is a common problem worldwide, which is considered as one of the main reasons for project failure. Bangladesh construction industry is no exception. This study investigated the main causes of delay in large building construction projects in Bangladesh. A questionnaire survey was conducted to determine the causes of delay from owners, consultants, and contractors of large building construction projects. About 70 respondents participated in the survey. Using the importance index analysis, the study identified 10 most important causes of delay from a list of 30 different causes. Ten most important causes were: (1) lack of experienced construction manager, (2) lowest bidder selection, (3) funding shortage by owner, (4) lack of proper management, (5) improper planning and scheduling, (6) lack of skilled workers, (7) site constraints, (8) contractors' cash flow problems during construction, (9) escalation of resources price, and (10) contractors' excessive workload. Furthermore, Kruskal-Wallis test indicates that there is no significant variation exists among the three group of respondents, ie owners, consultants and contractors.

본 연구는 회계 보수주의와 경영자 초과보상 사이의 음(-)의 관련성을 분석하고 이들의 관계가 회계성과에 대한 경영자 유인보상 강도가 높을수록 증가하는지에 대해 살펴본다. 이를 위해 2012년부터 2016년까지 한국 증권거래소의 상장기업 중 12월 결산 제조업만을 대상으로 총 2,755기업-연도를 최종 표본으로 분석에 활용하였다. 본 연구의 분석결과는 다음과 같다. 첫째, 회계보수주의와 경영자 초과보상은 통계적으로 유의적인 음(-)의 관련성이 있는 것으로 분석되었다. 이는 경영자 보상이 기업성과와 연계될 경우 경영자는 자신의 보상을 극대화하기 위해 자산이나 회계이익의 과대계상을 통하여 미래 현금흐름 추정치를 왜곡할 유인을 가진다. 이에 대해 회계 보수주의가 경영자의 회계선택을 제한하여 기회주의적 행위를 감소시킬 수 있기 때문에 경영자에게 지급되는 초과보상 역시 감소한 것으로 해석할 수 있다. 둘째, 회계보수주의와 경영자 초과보상의 음(-)의 관련성은 회계성과에 대한 경영자 유인보상 강도가 높을수록 증가한다는 실증결과를 발견하였다. 회계성과에 대한 경영자 유인보상 강도가 높을수록 경영자는 자신의 보상을 극대화하고자 회계성과에 대한 이익조정 유인을 가지며 초과보상을 획득할 가능성이 높다. 따라서 회계성과에 대한 경영자 유인보상 강도가 높다는 것은 초과보상으로 인한 사후정산문제가 심각해질 수 있다는 점을 의미한다. 이 경우 회계성과에 대한 경영자 유인보상 강도가 높을수록 경영자 보상계약에 있어서 보수주의의 역할 및 유용성은 더욱 커질 것이므로 보수주의와 초과보상에 대한 음(-)의 관련성이 더욱 증가한 결과로 해석된다. 본 연구는 Watts(2003)에 의해 이론적으로 제시된 경영자 보상계약에 대한 회계보수주의의 유용성과 관련하여 실증적 증거를 제시했다는 측면과 보수주의가 정보이용자들의 투자의사결정에 유용한 도구로 활용될 수 있다는 추가적인 근거를 제시했다는 점에서 의미가 있을 것이다.

본 논문에서는 초고속 패킷 스위치 네트워크에서 VoD나 HDTV, VoIP같은 고품질 스트리밍 서비스의 QoS를 보장하는 패킷 스케줄러의 구조 및 제어방법을 제시한다. 스트리밍 서비스는 버스트 데이터 응용서비스보다 더욱 엄격한 QoS(jitter, delay, packet loss)보장을 요구한다 또한 스트리밍 서비스는 다른 플로우들의 동작에 상관없이 끊김 없는 서비스를 제공하기 위해 각 플로우별로 최소 대역 보장과 종단간 지연조건을 보장해야 한다. 이들 요구조건들을 만족하기 위해, 패킷 스케줄러는 플로우들이 다른 플로우의 영향을 받지 않도록 분리하고, 각 플로우들에게 종단간 지연 보장을 제공해야 한다. 그리고 각 플로우들에게 요구되는 최소 대역폭을 할당해야한다 지금까지 많은 벤더들이 10Gbps급 트래픽 관리기 칩을 개발하였지만 대부분 칩들은 고품질 스트리밍 서비스를 지원하지 못하는 단점이 있다. 따라서 본 논문에서는 상용 TM칩들의 단점 및 스트리밍서비스의 트래픽 특성을 조사하고, 제안한 패킷 스케줄러의 하드웨어 구조를 제시한다. 그리고 마지막으로 제안한 스케줄러의 시물레이션 결과를 분석하였다.

This study describes approaches to fisheries management that restrict access by fishers to an area in some way. When fishery closure is established as a technical conservation measure it is a form of input control as a Korea fisheries management system. There are many compelling reasons why a fisheries manager should seriously consider closed areas and/or time restrictions, either as a complement to other measures or as the primary facet of the Korean fisheries management strategy. Fishery closures have been shown to be effective in many fisheries and are an important tool in the management armoury. In many respects justifications for their use and the process of implementation are likely to be relatively straightforward compared to permanent area closures. From a Korean fisheries management perspective, the benefits that flow from fishery closures are usually less easy to predict than for other management measures. Moreover, even if one accepts that implementation of fisherg clossures will provide higher production levels in adjacent fished areas, the potential benefits may often be in danger of being largely dissipated. If, for example, the fishery remains open access, the increased production is likely to attract new entrants into the fishery, thereby driving it back towards bioeconomic equilibrium. From a Korean wider fisheries conservation perspective, however, fishery closures have important and clearly defensible roles to play and some form of zoning arrangement will often effectively serve conservation values. Given the increasing trend towards the establishment of national networks of fisherg closures, it seems likely that fisheries managers throughout the world will need to ensure that they are familiar with the issues surrounding these approaches. The importance of being explicit about the goals for fishery closures in Korea have been continually emphasised throughout this study. There may, of course, be multiple justifications for the measure, in which case it is important to try and specify them in order of priority.

Nurses use a nursing process. that is a scientific approach method. in order to understand the clients' condition and to solve their problems. Professional nurses have accepted the nursing process as a standard framework for nursing activities, and the first step of the nursing process is nursing assessment. The purpose of this study was to develop a nursing assessment tool for emergency patients. Assessment is a first step in the nursing process, and scientific assessment helps to better understand the patients. Thus the development of an assessment tool for emergency patients will improve of nursing quality and advance to efficacy of emergency room(ER) management. The study involved the development of a conceptual framework, preliminary tool, content validity verification process. and reliability verification process. The conceptual framework was developed through a review of the literature. and preliminary tool was developed from the conceptual framework that based on care flow sheet' developed James A. Haley. The preliminary tool was evaluated for validity and reliability by seven experts, one ER nurse manager, two ER head nurses, two emergency medicine doctors. and two ER charge nurses and by ten nurses with one to five year careers in ER nursing. The results of this study was as follows 1. The conceptual framework which was developed was composed of three parts. They were triage criteria, first assessment and secondary assessment. 2. The preliminary tool which was developed had 31 items based on the conceptual framework. 3. To test expert validity a 4-point scale was used. items which had gained 3-4 points from six persons of the seven experts were selected. All 31 items from the preliminary tool were selected. 4. The reliability test was done by ten nurses educated in the use of the assessment tool. Two pairs of nurses simultaneously assessed the same patients. A total agreement percentile was calculated and result was 87.3% agreement. 5. After the validity and reliability testing. the final emergency patient nursing assessment tool was finalized with 31 items. and a check-list for the responses. This study concludes that the tool which was developed is both valid and reliable will advance quality care for emergency patients. This emergency nursing assessment tool was also found to be an adequate tool for assessment of emergency patients.

The proper functioning of critical points on transport infrastructure is decisive for the entire network. Tunnels and bridges certainly belong to the critical points of the surface transport network, both road and rail. Risk management should be a holistic and dynamic process throughout the entire life cycle. However, the level of risk is usually determined only during the design stage mainly due to the fact that it is a time-consuming and costly process. This paper presents a simplified quantitative risk analysis method that can be used any time during the decades of a tunnel's lifetime and can estimate the changing risks on a continuous basis and thus uncover hidden safety threats. The presented method is a decision support system for tunnel managers designed to preserve or even increase tunnel safety. The CAPITA method is a deterministic scenario-oriented risk analysis approach for assessment of mortality risks in road tunnels in case of the most dangerous situation - a fire. It is implemented through an advanced risk analysis CAPITA SW. Both, the method as well as the resulting software were developed by the authors' team. Unlike existing analyzes requiring specialized microsimulation tools for traffic flow, smoke propagation and evacuation modeling, the CAPITA contains comprehensive database with the results of thousands of simulations performed in advance for various combinations of variables. This approach significantly simplifies the overall complexity and thus enhances the usability of the resulting risk analysis. Additionally, it provides the decision makers with holistic view by providing not only on the expected risk but also on the risk's sensitivity to different variables. This allows the tunnel manager or another decision maker to estimate the primary change of risk whenever traffic conditions in the tunnel change and to see the dependencies to particular input variables.

Controlling food materials, is getting more significant in hotel management nowadays as the selling of food beverage continue to rise. F&B managers have been required to have new management of the food materials by a fierce competition, an increase in cost, the shortened span of product life and customer's demand that is becoming more various and sophisticated since Korea was placed under the influence of IMF. I'm going to analyze the factors that cause waste and loss through a series of the process to purchase inspect, store food materials, make a product with that materials and sell the product in order to make more profits by making the circulation of the food materials easier and more efficiently. I studied how 3 chain hotels of A group purchase, store the food materials and control stock. I made up questionnaires about the circulation and control of food materials to 107 cooks in order to know what the cooks who are working at the hotel regard as a real problem and a practical solution. This research indicates that purchasing, producing and selling departments don't establish the mutual connection, a professional purchasing manager is strongly needed and there is difficulty in predicting the proper timing to supply. Also the research shows that A hotel group controls the food materials by analyzing the amount of consumption, stock, setting up the period of validity and uses slowly moving food materials in stock mainly by introducing the menu that aims at four seasons. As a result, the research suggests that we should introduce the concept of food producing factory, as it were, Central Kitchen that is based on the network among various kitchens to improve the flow of the food materials.
