The purpose of this study is to identify specific patterns of Sasimi consumption in Korea using cluster analysis. The data applied in the analysis were collected from five major cities in Korea through telephone interview with trained surveyors. This study investigated three major topics; 1. Korean people prefer to eat Sasimi at the restaurants rather than at-home. 2. The quality of Sasimi is different according to where the eating place is located such as seaside or inland. 3. Determinants of Sasimi Consumption are different according to population characteristics, sex or occupation. The main findings of the study can be summarized as following three points. Firstly, Koreans preferred to eat Sasimi out 83.3% of respondents chose eat-out rather than eat-at-home. These are especially popular with men, 40' years older, self-employed, lived in capital area. Secondly, satisfaction level of Sasimi consumption was good in Choong-Cheung province. Since Chung-Cheong Province was located in the inland, the chance to eat Sasimi is lower than seaside. Thirdly, consuming decision factor of Sashimi was different across groups. None of decision factors take effect on Group 1 while indigenous variable of Sashimi has effect on Group 2 and external variable has effect on Group 3. Therefore, in order to increase Sashimi consumption, it is necessary to at-home consumption of Sashimi should be improved. Moreover, it is necessary to develop marketing strategy which fits in regional characteristics and to have government assistance.

In regions of high shear forces in composite bridges, headed stud shear connectors need to be arranged with a small spacing in order to satisfy the design requirement of resisting the high interface shear force present at this location. Despite this, studies related to groups of headed studs are somewhat rare. This paper presents an investigation of the static behaviour of grouped stud shear connectors in high-strength concrete. Descriptions are given of five push-out test specimens with different arrangements of the studs that were fabricated and tested, and the failure modes, load-slip response, ultimate load capacities and related slip values that were obtained are reported. It is found that the load-slip equation given by some researchers based on a single stud shear connector in normal strength concrete do not apply to grouped stud shear connectors in high-strength concrete, and an algebraic load-slip expression is proposed based on the test results. Comparisons between the test results and the formulae provided by some national codes show that the equations for the ultimate capacity provided in these codes are conservative when used for connectors in high-strength concrete. A reduction coefficient is proposed to take into account the effect of the studs being in a group.

Cementitious composites are multiphase heterogeneous materials with distinct dissimilarity in strength under compression and tension (high under compression and very low under tension). At macro scale, the phenomenon can be well-explained as the material contains physical heterogeneity and pores. But, it is interesting to note that this dissimilarity initiates at molecular level where there is no heterogeneity. In this regard, molecular dynamics based computational investigations are carried out on cement clinkers and calcium silicate hydrate (C-S-H) under tension and compression to trace out the origin of dissimilarity. In the study, effect of strain rate, size of computational volume and presence of un-structured atoms on the obtained response is also investigated. It is identified that certain type of molecular interactions and the molecular structural parameters are responsible for causing the dissimilarity in behavior. Hence, the judiciously modified or tailored molecular structure would not only be able to reduce the extent of dissimilarity, it would also be capable of incorporating the desired properties in heterogeneous composites. The findings of this study would facilitate to take step to scientifically alter the structure of cementitious composites to attain the desired mechanical properties.

The purpose of this study was to modify a Flared Skirt for women according to the somatotype of lower body. The subjects for the wear test were 3 students, who were in mean${\pm}1{\sigma}$ each somatotype. As seen in the study, it was found out that there was a difference in three dimensional shape of the lower part of the body even in the group of whom the body heights, measured by Martin's system, are alike. Due to such a difference in the three dimensional shape of the lower part of the body, it was found out to be a difference in drapability of the flare skirts. In order to have better fitness of the lower part of the body and to raise the visual effect, therefore, it is suggested that there need to develop a new model of the flare skirts considering three dimensional shape of the lower part of the body for the wearer or to take complementary measures for each body shape in case of applying traditional model.

To improve limitations of fuzzy PI controller especially when applied to high order systems, we propose two types of fuzzy logic controllers that take out appropriate amounts of accumulated control input according to fuzzily described situations in addition to the incremental control input calculated by conventional fuzzy PI controllers. The structures of the proposed controller were motivated by the problems of fuzzy PI controllers that they generally give inevitable overshoot when one tries to reduce rise time of response especially when one tries to reduce rise time of response especially when a system of order higher than one is under consideration. Since the undesirable characteristics of the fuzzy PI controller are caused by integrating operation of the controller, even though the integrator itself is introduced to overcome steady state error in response, we propose two fuzzy controllers that fuzzily clear out integrated quantities according to situation. The first contr ller determines the fuzzy resetting rate by situations described fuzzily by error and error rate, and the second one by error and control input. The two structures both give reduced rise time as well as small overshoot. To show the usefulness of the proposed controller, that are applied to systems that are difficult to get satisfactory response by conventional fuzzy PI controllers.

기업의 경영환경은 급속히 변화하고 있으며 특히, 새로운 경영패러다임으로 가치중심의 경영사고는 급속히 그 중요성을 인정받고 있다. 이러한 경영환경의 변화에 대한 신경영기법의 활용에는 원가/관리회계정보가 기초적 역할을 수행하고 있는데, 과거 지향적인 정보보다는 실시간적이면서 동시에 미래지향적인 정보를 제공해야만 경영의사 결정에 도움을 줄 수 있다. 이러한 실시간적 정보와 미래 지향적인 정보의 중요성을 인식하면서 조직을 가치창출 중심적인 방향으로 움직이게 하기 위해서는 조직내 구성원 및 조직의 성과평가가 중요한 문제로 대두될 수 있다. 그러나 과거와 같이 전통적인 성과측정치로 재무적 측정치를 사용하면 조직의 유효성을 증진시키는데 한계가 있을 뿐만 아니라 가치창조를 저해시킨 소지도 있다. 따라서 앞으로 조직을 가치 지향적이 되게 하기 위해서는 조직의 구성원 및 조직단위의 성과를 측정할 때, 재무적인 측정치와 비재무적인 측정치의 균형있는 사용을 강조하는 Balanced Scorecards개념을 도입하는 것이 바람직 할 것이다.
