Composition depending on the development of industrial sites are located just within the existing facilities are hoping to become a retention, in accordance with the law will impose a liability amount. Then calculating the profit and loss analysis of the retention is required. In other words, the composition of the industrial site will be retained for existing facilities and the amount of the profit is necessary to analyze. In this study, the calculation of expenses and the income of retained existing facilities will be presented with analytical methods. Especially the existing cases of dispute with the results of the adjustment and the calculation of contributions for a range of benefits associated with the analysis according to 'The Industrial Sites and Development Act', the following conclusions were drawn. According to 'The Industrial Sites and Development Act', the facility at the industrial site composition within the limits of increasing the convenience of being charged is reasonable. In particular, the industrial site of buildings located within existing facilities depending on the composition and future industrial sites are public facilities available for the facility to consider the possibility of calculating contributions to be reasonable. Additional benefits which can be the land prices, tax exemptions, and increasing efficiency of land use for the benefits are not yet realized the benefits against the expenses side, as well as imposing double taxation. Therefore, the heavy emphasis on convenience is not considered to be reasonable. Including in the industrial site, the cost of damages caused, that is, noise, pollution, and the defective product possibility should be considered a side opinion, but it still does not promote the development of states estimated the cost of the damage is not right to be counted. Therefore, this facility should not be included in calculating contributions.

This paper investigates the effects of inlet turbulence conditions and near-wall treatment methods on the heat transfer prediction of gas turbine vanes within the range of engine relevant turbulence conditions. The two near-wall treatment methods, the wall-function and low-Reynolds number method, were combined with the SST and ${\omega}RSM$ turbulence model. Additionally, the RNG $k-{\varepsilon}$, SSG RSM, and $SST_+{\gamma}-Re_{\theta}$ transition model were adopted for the purpose of comparison. All computations were conducted using a commercial CFD code, CFX, considering a three-dimensional, steady, compressible flow. The conjugate heat transfer method was applied to all simulation cases with internally cooled NASA turbine vanes. The CFD results at mid-span were compared with the measured data under different inlet turbulence conditions. In the SST solutions, on the pressure side, both the wall-function and low-Reynolds number method exhibited a reasonable agreement with the measured data. On the suction side, however, both wall-function and low-Reynolds number method failed to predict the variations of heat transfer coefficient and temperature caused by boundary layer flow transition. In the ${\omega}RSM$ results, the wall-function showed reasonable predictions for both the heat transfer coefficient and temperature variations including flow transition onset on suction side, but, low-Reynolds methods did not properly capture the variation of the heat transfer coefficient. The $SST_+{\gamma}-Re_{\theta}$ transition model showed variation of the heat transfer coefficient on the transition regions, but did not capture the proper transition onset location, and was found to be much more sensitive to the inlet turbulence length scale. Overall, the Reynolds stress model and wall function configuration showed the reasonable predictions in presented cases.

Due to the decrease in coastal productivity and deterioration in the quality of ecosystem which result from the excessive overfishing of fisheries resources and the environmental pollution, fisheries resources in the Korean waters hit the dangerous level in respect of quantity and quality. In order to manage sustainable and effective fisheries resources, it is necessary to suggest the potential yield (PY) for clarifying available fisheries resources in the Korean waters. So far, however, there have been few studies on the estimation methods for PY in Korea. In addition, there have been no studies on the comparative analysis of the estimation methods and the substantial estimation methods for PY targeted for large marine ecosystem (LME) For the reasonable management of fisheries resources, it is necessary to conduct a comprehensive study on the estimation methods for the PY which combines population dynamics and ecosystem dynamics. To reflect the research need, this study conducts a comparative analysis of estimation methods for the PY in the Korean waters of the East Sea to understand the advantages and disadvantages of each method, and suggests the estimation method which considered both population dynamics and ecosystem dynamics to supplement shortcomings of each method. In this study, the maximum entropy (ME) model of the holistic production method (HPM) is considered to be the most reasonable estimation method due to the high reliability of the estimated parameters. The results of this study are expected to be used as significant basic data to provide indicators and reference points for sustainable and reasonable management of fisheries resources.

합리적 통행경로는 "경로를 노드 또는 링크의 순서로 표현할 때, 경로를 구성하는 노드의 반복은 존재해도 링크의 반복은 존재하지 않는다"는 원리에 근거한다. 최적경로 탐색과정에서 합리적 통행현상을 포함하는 방법은 링크로 구성된 표지(Link-Based Label)를 적용하는 방안이 적용하기 용이하다. 링크표지를 활용하는 경우 링크의 중복 표현을 허용되지 않는 상황에서 노드의 중복표현이 가능하여 합리적인 통행을 원칙적으로 보장될 뿐만 아니라 목적지에서 출발지로 경로를 역 추적(Backward Trace)하는 과정에서 전 링크(Pvevious Link)의 단일정보만 이용하므로 Bellman의 최적원리(Optimality Condition)에 의한 최적해(Optimal Solution)가 보장된다. 본 연구는 다수의 경로를 선정함에 있어 합리적 통행행태를 고려하기 위한 링크표지고정방식(Link-Based Label Setting)을 제안한다. 기존에 표지고정(Label Setting)을 기반으로 제안되었던 노드기반 다수경로알고리즘을 기반으로 링크표지로 전환하는 방안을 개발한다. 또한 알고리즘의 대규모 교통망에 적용한 수행결과를 통해 대안경로정보제공을 위한 현실적용의 문제점을 도출하고, 도로의 연속주행을 보장하려는 운전자의 경로선택행태를 반영하는 방안에 대해 검토한다.

Recently, several attempts have been made to provide reasonable information on unusual severe weather phenomena such as tolerant heavy rains and very wild typhoons. Quantitative precipitation forecasts and probabilistic quantitative precipitation forecasts (QPFs and PQPFs, respectively) might be one of the most promising methodologies for early warning on the flesh floods because those diagnostic precipitation models require less computational resources than fine-mesh full-dynamics non-hydrostatic mesoscale model. The diagnostic rainfall model used in this study is the named QPM(Quantitative Precipitation Model), which calculates the rainfall by considering the effect of small-scale topography which is not treated in the mesoscale model. We examine the capability of probabilistic diagnostic rainfall model in terms of how well represented the observed several rainfall events and what is the most optimistic resolution of the mesoscale model in which diagnostic rainfall model is nested. Also, we examine the integration time to provide reasonable fine-mesh rainfall information. When we apply this QPM directly to 27 km mesh meso-scale model (called as M27-Q3), it takes about 15 min. while it takes about 87 min. to get the same resolution precipitation information with full dynamic downscaling method (called M27-9-3). The quality of precipitation forecast by M27-Q3 is quite comparable with the results of M27-9-3 with reasonable threshold value for precipitation. Based on a series of examination we may conclude that the proosed QPM has a capability to provide fine-mesh rainfall information in terms of time and accuracy compared to full dynamical fine-mesh meso-scale model.

UCP 600 will now come into effect on 1 July 2007, giving practitioners more than six months to prepare for the change. The vote on the UCP was also a favourable vote on eUCP Version 1.1 which was amended to bring it into conformity with the new rules. ICC Banking commission unanimeusly approved the revised UCP 600 on 26 October 2006 in paris convention. The most important revision of UCP600 have altered the technical and difficult to understand wording of UCP500 into plain simple precise and concise language, The singuler achievement of UCP600 is its elimination of phrase like "reasonable care" "reasonable time" and "an it's face" from the rule. The introduction of separate articles 2 and 3 on "Definitions" and "Interpretation" which contain the concept of "honour" along with the inclusion of certain ISBP wording in UCP, should bring about far greater clarity and precision than in many of the contentions articles in UCP500. The definition of negotiation should help lay to rest the controversies surrounding the terms of negotiation. The removal of reasonable time and the replacement by five banking days should speed the process and make L/Cs more attractive in the market, nevertheless UCP600 have many problems in appling it in practical field. For example the definition of credit, negotiation and purchase it's accepted or undertaken payment draft by accepting bank or deferred payment bank, the second advising bark's position etc. so, I will introduce in this thesis the important revised articles of UCP600 and investigate the problems in applying it in practicle field with reference to the specialist's opinion of the practical field and ICC opinions of drafting Group.
