This study is to understand cotton Tyeollik construction of the middle Chosun Period through the reconstruction of tyeoilik which was excavated from lady kim's tomb (from sooncheon). The form of excavated Tyeollik classified into two types by the location of waistline. The structure of excavated tyeollik classified into three types by the construction(one-layer, two-layer, cotton/quilt) The form type change according to the period. The change of the form type has the close relation structure type in the tyeollik. Cotton-tyeollik belongs to the form of the front time. The construction of cotton tyeollik is similar with the one-layer Tyeollik Exception the construction of git(collar) and the size and direction of the fold. The surface pattern is composed of two-pieces but the liner is one-piece in the Git(collar). and In The size of fold surface is o.2-o.3cm, and liner is 0.5-0.8cm. The direction of fold in the liner is the contrast with the surface.

The purpose of this study was to understand the relationship between life style that a consumer is pursuing and purchasing frequency among the purchasing behaviors in internet shopping mall. As a result, the factors of life style with respect to purchasing attitude of the consumer were categorized into 'price advising type', 'price-quality identifying recognition type', 'brand-oriented type', 'shopping time-effort non-investment type', and 'price-quality comparing type'. It showed that there was a close relationship between the life style and the purchasing frequency in internet shopping mall and that there was a significant influence between the life style and the purchasing frequency. The result of this study indicated that the relationship between the life style and purchasing frequency in internet shopping mall was actualized by measuring the purchasing inclination of the consumer under various situations of psychologically descriptive characteristics and desire and simulation. Therefore, this fact suggests that it is very important to measure the accurate purchasing attitude of its consumer when setting up the marketing strategy of internet shopping mall.

A turbopump system composed of two pumps and one turbine is considered. The turbine composed of a nozzle and a rotor is used to drive the pumps while gas passes through the nozzle, potential energy is converted to kinematic energy, which forces the rotor blades to spin. In this study, an aerodynamic design of turbine system is investigated using compressible fluid dynamic theories with some pre-determined design requirements (i.e., pressure ratio, rotational speed, required power etc.) obtained from liquid rocket engine (L.R.E.) system design. For simplicity of turbine system, impulse-type rotor blades for open type L.R.E. have been chosen. Usually, the open-type turbine system requires low mass flow rate compared to close-type system. In this study, a partial admission nozzle Is adopted to maximize the efficiency of the open-type turbine system. A design methodology of turbine system has been introduced. Especially, partial admission nozzle has been designed by means of simple empirical correlations between efficiency and configuration of the nozzle. Finally, a turbine system design for a 10 ton thrust level of L.R.E is presented.

This research is about the reproduction of Baekje's armor-lamellar made for the Hanseong Baekje Museum exhibition. The purpose of the research are as follows. First, to categorize Baekje armor by type based on ancient documents and the excavated relics. Second, to reproduce categorized armor that provide a visual work for use in diverse areas. Baekje armor can be examined through the ancient records and several excavated relics. The results of the research are as follows. First, Baekje armor can be categorized into four types by material: 1) brass 2) iron 3) leather 4) bone. The can also be categorized into three types by finishing a) Hyeongnyubongnyun type (the leather skin interweaves with the lamellar armor method) b) Hyeokpobongnyun type (the method which wraps around the edges of leather skin) c) leather cloth added to clothe type. Second, we reproduced metal armor, iron armor and leather armor using brass, iron and leather (but not bone). Each type of armor were made life-size for exhibition purposes. We used Hyeongnyubongnyun method, Hyeokpobongnyung method and leather cloth; in addition, reproductions were made based on the Yangdang method that connected the front and the back from both sides of the shoulders so it can be open and close at the side part.

The purpose of this study lies in examining the characteristics of differentiated body types for plus-size women and obtaining basic data for the wide-ranging choices of ready-made clothing in a consumer's place. The results of this study displayed no significant differences for subjects in their 30s and 40s in comparison to standards by ages but showed a significant difference with subjects in their 50s when compared with the data from Size Korea (2004). Research data in the height and length categories were lower, and the majority of data from the other categories were higher. In order to analyze the characteristics of a plus-size woman's body, 4 factors were differentiated into 3 types with 17 categories: Factor 1 was the element of the thickness of the trunk, factor 2 was the element of the thickness of the lower body and legs, factor 3 was the element of shoulder size and factor 4 was the element of the upper body length. The accumulation rate was shown to be 74.47%. The characteristics for each type were as follows: Type 1 is a body type with a relatively thin waist, small width and girth of upper body and curvy lower body, type 2 is the average body type, and type 3 is a body type with big breasts and abdominal obesity. The standard body type belonged to type 2. According to the correspondency test between age and type, the characteristics of type 1 corresponded relatively close to the measures of subjects in their 40s and relatively far from subjects in their 30s to 50s while type 2 and type 3 appeared to be similar to subjects in their 50s.

본 연구는 지역별 우수수업 동영상에서 나타나는 수학적 의사소통이 어떻게 이루어지고 있는지를 분석하여 양질의 수업을 찾아 교사의 수업 관행에 도움을 주고자한 것이다. 교사와 교실 전체 간에 이루어지는 담화를 중심으로 수업을 분석하기 위해 다음과 같은 연구문제를 설정하였다. 첫째, 지역별 우수수업 동영상의 수학적 의사소통 수업유형은 무엇인가? 둘째, 지역별 우수수업은 의사소통이 어떻게 이루어지고 있는가? 셋째, 담화중심 수업의 수학적 의사소통 수준은 어떠한가? 공개된 24개의 수업을 수업 유형에 따라 분류한 결과 초등학교 수학 수업의 특성상 조작 중심수업 유형이 가장 많은 것으로 나타나 다른 유형의 수업도 좀 더 이루어질 필요가 있음을 알 수 있었다. 그리고 교수 학습 지도안에서 수학적 의사소통 능력을 고려한 수업은 5개이며 이 중 1개 수업만이 수학적 의사소통 능력을 인지적 영역에 포함시키고 있어, 수학적 의사소통 능력에 대해 교사가 정확히 알 필요가 있었다. 또한, 학생 간 질문하기를 수업에 반영할 필요가 있었다.

The purpose of this study is for size suitability and fitness improvement for Korean 20's women. This study has classified hip types of 20's women by the 6th Korean Anthropometric Survey(Size Korean), then compared their lower body-type by hip types each other. The results are as follows. Factor analysis in sorting hip types can be explained 77.72% by nine factors. And cluster analysis can be divided into three types. Type 1 is referred to as a general type which has the largest size in the 'Hip circumference', but the buttocks's horizontal sizes are in the middle size besides the hip line. Type 2 is referred to as a protruding type in upper buttocks which is large in protruding volume of upper buttocks, but the buttock's horizontal sizes are small including 'Hip circumference', and buttock's horizontal section form close to circle. Type 3 is referred to as a type which is contrary to Type 2. Type 3 is small in protruding volume of upper buttocks, but large in lower buttocks, and the protrusions in whole buttocks are small, so the side view of Type 3 made gentle fit shape. By these results, the study could classify lower body of 20's women, and it can be basic data for new sizing systems and pattern development of bottoms.

Schizopora paradoxa is a white rot fungus showing great variation in hymenophoral configuration. It has been often treated as close to Irpex or Hyphodontia and frequently confused with S. flavipora which was identified as an unrecorded species in Korea. Distinct features including sizes of basidia and basidiospores as well as hymenophoral shape make S. paradoxa differ from S. flavipora. Remarkable characters of hymenophores and microscopic structures are described and their significance is discussed for the taxonomy of Korean Schizopora.

Many hydraulic structures are damaged by under flood flow and storm waves year after year. Many cases of dike and breakwater failure are caused by the suck out of sand from behind the revetment. This type of failure will be in close relation to the dynamic behavior of sand bed around the revetment. In this paper, from this point of view we investigated the basic characteristics of such sand movement by small model tests and tried to explanation the hydro- and soil mechanical mechanism of this phenomenon theoretically.
