  • 일반적으로 PSC 교량은 여러개의 강선을 포함하며, 이러한 강선들의 긴장순서에 따라 정착부의 파열력의 크기는 좌우된다. 그럼에도 불구하고 강선긴장순서에 대한 연구부족으로 강선긴장시 긴장순서를 설계자의 경험이나 직관에 의하여 결정하고 있다. 본 연구에서는 정착부의 파열력을 산정하는 여러 방법에 대하여 고찰한 후, 가장 합리적인 해석방법을 선택하여 PSC 교량중에서 가장 대표적인 PSC빔교와 PSC박스거더교에 대하여 해석을 통한 합리적인 긴장순서를 결정하였다. 본 연구에서 제시한 방법은 PSC교량 정착부의 파열력을 최소화하는 강선긴장순서 결정에 유용한 방법이 될 것이다.

  • In order to provide a scientific foundation for herb application in landscape, the photographs were taken from the herb landscape in urban green space and sightseeing garden. The questionnaire-based survey was also applied to analyze the cognitive situation of herb. Most investigators love herb, but have a low level of herb; Interviewees' consideration of herb function lie in ornamental, healthcare and medical treatment; The bulk of the visitors think herb landscape is insufficient; Investigators' preferences for herb application forms are landscape edging and combining with stone. We also probe into the optimum allocation form combining herb with landscape elements. When we combine herb with landscape water or landscape architecture, artistic conception and reasonable plant allocation should be considered; When we combine herb with landscape path or garden ornament, reasonable plant disposition and appearance and practical collocation should be thought over; When we combine herb with flower-border, richly colored landscape and reasonable plant allocation should be deliberated on.

  • In this paper, to prevent overspending of the CM Fee, Agent CM for the normal work-oriented, Willing to separate order model being used in the construction, using a multi-national grouping Go to offer the right company, a number of groups according to the appropriate CM Fee setting is aimed to suggest a reasonable basis. This paper does not use the domestic point of order characteristic of the model, and using a different theory of affinity grouping projection method is presented. The main disadvantage of the domestic order model because it is a contractual relationship, the contractual relationship as unified as possible by the most reasonable way of construction and construction capabilities and commercialization agreement upon the ability of companies also expect to be very helpful. The grouping by using the multi-order construction of the separation problem of the increase and thus the management object construction type administration was to solve the problem.

  • The economic order quantity(EOQ) is a robust quantity, and it is largely insensitive to reasonable errors in the estimation of most of its parameters. Optimal EOQ and reorder point which are not sensitive to the estimates of the various cost model parameters for Kim and Park's model are determined. This of Taguchi's parameter design which finds a robust EOQ and reorder point using reasonable cost structure on the assumption of normally distributed quality characteristic. A numerical example is also presented to illustrate the proposed procedure and computer aided numerical experiments for selected values of backordered fractions and standard deviations are performed.

  • With the advance of technology, the order-made clothes gradually give way to ready-made clothes. It is already well-known that more than 80 percentage of Japanese are choosing ready-made clothes while less than 5 persons out of 100 are spending their money and valuable time to have their clothes order-made in the United States. One of the fundamental steps to reach the system of mass production of clothes is recognized as a 'reasonable' sizing system. 'Reasonable' can be interpreted 'optimum' in the sense of minimum loss from both producers and customers. This paper desires the methodology to obtain the sizing system utilizing the human body measurement data, The suggested methodology could be extended to the sizing system for the design of other items including industrial equipments.

  • The purpose of this study is to examine the effects of a degree of discretization in the direction of longitudinal dam axis on the results of three dimensional fill dam dynamic analysis. In this study, the three dimensional dynamic analyses of the existing 'H' dam which is modeled with a different degree of discretization were carried out. From these results, the fundamental frequency of the dam and the responses at the dam crest such as acceleration and settlement were compared and analyzed. It was concluded that the size of finite element discretized in the direction of the longitudinal axis mush be smaller than 1/8 of dam length in order to obtain the reasonable fundamental frequency and response of acceleration and mush be smaller than 1/10 in order to obtain the reasonable settlement behaviors from the three dimensional dynamic analysis of the fill dam.

  • Recently the Supreme Court held that "in cases in which a patient suffering from a mental disorder attempts to commit suicide, fails, and then succeeds in a subsequent attempt, the following circumstances must be present in order to acknowledge reasonable causation between the negligence of the hospital with regards to taking care of the patient and the death of the patient; there must have existed negligence on the part of the hospital with regards to their failure to stop the 1stsuicide attempt, injurious aftereffects must have been caused to the patient by the1stsuicide attempt, and said aftereffects must have been the main cause for the 2nd successful suicide attemtp." This, in effect, lessens the requirements of past holdings of the Supreme Court which held that "to acknowledge reasonable causation between the negligence of the hospital and the patient that commits suicide, the patient must have experienced such severe physical and mental suffering from the previous attempt so that they could not help but choose to commit suicide". The fact that the Supreme Court did not clearly state such changes in their view on this matter should be corrected. Also, the fact that the court only held the hospital liable for damages of less than 50 million won, only calculating damages up to the point when the deceased passed, is inadequate compared to other cases and should be corrected.

  • Article 35 of the CISG defines standards for determining whether goods delivered by the seller conform to the contract in terms of type, quantity, quality, and packaging. When we apply these article 35(1), (2) of the CISG to the business connection, we will face several issues in the business connection. Fist, we will face the interpretation of contracts. When we interpret the contract, we must remember the article 8 of the CISG. Statements made by and other conduct of a party are to be interpreted according to the intent of parties. Therefore parties of contract must describe their intent correctly. Second, we must make out a contract in written about the promised contents. And it is needed to insert a merger clause in order to prevent part of contract from disagreeing with each other. Third, there are several interpretation of fitness for the purpose for which the goods would ordinarily be used. So it is important to describe the quality standard to be applied. If it does not describe the standard, it is helpful to apply the reasonable quality test. Fourth, there may be some doubt regarding the question of whose standard-that of the seller's or that of the buyer's state-is relevant in order to determine which characteristics the goods must have in order to be fit for their ordinary purpose. Ultimately, the question of the relevant standard is a matter of the interpretation of the contract.

  • Main aim of this paper is to find the best combination of numerical schemes for 2-D SPH simulation of wedge water entry. Diffusion term is considered as laminar, turbulent, and artificial viscosity. Density filter that seriously affects the pressure distribution is investigated by adopting no filter, first order filter, and second order filter. Validation of the results indicates that turbulent model and first order density filter can lead to more reasonable solutions. This simulation was then conducted for wedge water entry with wide range of deadrise angles including 10 degrees, 20 degrees, 30 degrees, 45 degrees, 60 degrees and 81 degrees, with extreme deadrise angles of 10 degrees, 60 degrees and 81 degrees being considered. Comparison of SPH results with BEM solutions has displayed favorable agreement. In two particular cases where experimental data are available, the SPH results are shown to be closer to the experiments than BEM solution. While, accuracy of the obtained results for moderate deadrise angles is desirable, numerical findings for very small or very large deadrise angles are also very reasonable.
