The purpose of study is to identify influences of attribution of university headquarters, executive direction and management, student three groups - establishment･ establishment, management, entrance - to the performance evaluation index. This study offers development plan of the public sector honors college by analysing difference in group consciousness to the comparative significance of performance evaluation index for co-creation. The study attempt to investigate attribution theory and difference in group consciousness based on the 1st actions of 3 group results(establishment･ establishment, management, entrance) affect the performance evaluation indexes. For that, this study has developed 19 indicators, 5 Items for performance evaluation using program logic model and AHP method focusing on the seokdang honors college of Dong-A University. Analysis was pronounced differences between groups consciousness. University headquarters perceived the number of people passing exams, employment rates than other groups as important factors because university provides various benefits to attract talented student. On the other hand, executive direction and management perceived performance index of consultation program, training, attendance, the number of host because student motivation recognized as important. Student who demand for education services are recognized scholarship benefits(budget), the number of people passing exams of imput･initiative outcome item as major factors by opportunity costs for entrance to university located in Seoul. The study results suggest need for student･parents satisfaction as key performance indicator, good communication within the 3 groups of public sector honors college in order to improve the quality of operation since awareness about 17 of 19 performance indicators was a big gap. The study shows need for maintaining consistency･durability in government s policy to foster motivated talent in the community and joint venture creation.

Front Points are told to be deeply related with viscera and bowels in oriental medicine. Since the Front Points are treated as response zone, it can be used for the diagnosis and treatment of disease in viscera and bowels. The location of Front Points are very similar to the several response zones in western medicine. Diagnostic aspect of Front Points to several response zones were discussed in here based on many thesis and reported laboratorial experiments. Front Points are located in the same latitude of viscera and bowels. So, diagnosis result in Front Points represent condition of each organs. Palpitation of the Front Points can make diagnosis of body surface and the organ beneath the body surface. Such use of Front Points for diagnosis can used as the treatment points also. Only three Front Points (LU-1, LI-14, GB-24) in lung, liver and gall bladder meridian are located on its meridian. The Front Points of Stomach (CV-12) cross its meridian or closely located to it. Unlike to those four Front Points that are matched to its meridian, other eight Front Points do not located or cross its meridian at all. It seems that the location of Front Points are decided by the location of organs and the conditions at a certain organ do not delivered by the meridians but delivered by main collaterals, tertiary collaterals and superficial collaterals instead. Among visceral response zones, Five Front Points (CV-3, CV-4, CV-12, LI-14, GB-25) are exactly matched to Head's response zone and other Front Points are closely matched to the Head's response zone. There are five Front Points (CV-12, CV-14, CV-17, LI-14, GB-24) that are matched with the location of pressing palpitation point and other Front Points are closely located to the pressing palpitation point. So far, it was clear that the Front Points do have important role as response points. Symptoms expressed to the Front Points were delivered conditions or symptoms occur in corresponding organ and the anatomical location of Front Points were also found near the corresponding organ. Diagnostic and therapeutic application of Front Points for Organ theory and in the Interpromotion-restraint of the five elements in oriental medicine can be made in future to increase its potential.

The purpose of this study is to develop standard reference materials for safety control of construction materials considering the required performance of standard materials including flow performance incorporating particles. The flow characteristics of concrete are very complicated depending on mixing proportions of constituent materials, admixtures, amount of mixing, type of mixer, time of mixing, temperature and so forth. Uncertainties and multidimensional properties of concrete have been evaluated through various studies but there are few researches for the development of standard reference material. In this study, based on the rheological concept, the flow performance of construction materials was evaluated to understand the properties of standard reference materials and was finally obtained representing materials which simulate the standard reference materials.

The RSS Reader is a software application that assist users easily to read and collect contents which are frequently changeable syndicated contents of RSS format that published on the web. This paper presents a formula software design based on RUP object-oriented design method for implementing the RSS Reader. We extract a use case based on requirements for implement of the RSS Reader and propose a domain concept model by. Using above artifacts, we extract event to generate between users and, the RSS Reader and logical architecture. So, we design classes and packages of the RSS Reader. As proposed a formula software design about the RSS Reader in early stage, it can make the RSS Reader with a variety of characters easily based on these. RSS 구독기는 웹에서 배포하고 많고 자주 변하는 RSS 포맷의 콘텐츠를 수집하여 구독자가 쉽게 구독할 수 있도록 도와주는 소프트웨어 애플리케이션이다. 본 논문에서는 RSS 구독기의 구현을 위하여 RUP 객체지향 설계 방법론에 의거한 체계적인 소프트웨어 설계를 제시하고자 한다.

Discrete topology optimization processes of structures start from an initial design domain which is described by the topology of constant material densities. During optimization procedures, the structural topology changes in order to satisfy optimization problems in the fixed design domain, and finally, the optimization produces material density distributions with optimal topology. An introduction of initial holes in a design domain presented by Eschenauer et at. has been utilized in order to improve the optimization convergence of boundary-based shape optimization methods by generating finite changes of design variables. This means that an optimal topology depends on an initial topology with respect to topology optimization problems. In this study, it is investigated that various optimal topologies can be yielded under constraints of usable material, when partial solid phases are deposited in an initial design domain and thus initial topology is finitely changed. As a numerical application, structural topology optimization of a simple MBB-Beam is carried out, applying partial circular solid phases with varying sizes to an initial design domain. 이산화 된 구조물의 위상최적화 과정은 균일하게 분포된 재료 밀도의 위상으로 표현되는 초기 설계영역을 시발점으로 한다. 최적화 과정 동안 구조물의 위상은 고정된 설계영역 내에 주어진 최적화 문제를 만족시키는 방향으로 변화하면서, 최종적으로 최적 위상의 재료 밀도 분포를 생산한다. Eschenauer et al.에 의해 제안되었던 설계영역 안에 구멍을 도입하는 개념은 원래 경계면의 최적화 문제에 대해 설계변수의 유한적인 변화를 촉진시켜 최적화의 수렴성 개선을 도모하기 위함이었으나, 위상최적화의 관점에서는 초기 위상의 정의에 따라 다양한 최적 위상이 생산되는 것을 의미한다. 본 연구에서는 초기 설계영역 안에 국소적인 솔리드 상을 도입해 초기 위상에 변화를 주었을 때, 한정된 재료 하에 구조물에 배치 가능한 다양한 최적 위상을 산출할 수 있음을 검증하였다. 수치 예제로서 초기 설계영역 내에 다양한 치수를 가지는 국부적인 원형 솔리드의 고정된 개수를 투입하여 간단한 MBB-보의 위상최적 설계를 수행하였다.

Purpose: To report a case of a macular pseudohypopyon in the right eye in bilateral Terson's syndrome. Case summary: During a right eye vitrectomy of a 56-year-old female patient who showed bilateral Terson's syndrome with subarachnoid hemorrhage, a macular pseudohypopyon was observed. In an oval-shaped subinternal limiting membrane cyst (4×2 diameter size disc) including the central fovea, white exudates with fluid levels were present. The macular pseudohypopyon in the right eye was suspected to have occurred during the absorption of the subinternal limiting membrane hemorrhage. In the left eye, white exudates were clustered in the central fovea. In the right eye, the central fovea was above the fluid level of the pseudohypopyon, and corrected visual acuity was 1.0 after 6 months. Two months after the operation, the pseudohypopyon was absorbed.
