This study is conducted to investigate the organization of Cheongunri in Cheong-song, as well as the characteristics of folk houses. In this study, 82 folk houses, including the villages, are surveyed; among them, 15 houses are intensively analyzed in terms of the structure of plane and the arrangement of space. The focus of study is on discovering an internal order system of villages and tracing a relationship between the characteristics of houses and the environmental factors. According to the results of the study, an Intrinsic order in Cheongunri is found to be related to the mountain axis, the road system, and the flow axis; and the form of folk houses is also found to be influenced by this order. The major characteristics of folk houses can be summarized as follows: (1) Most of the houses face east along the mountain axis, whereas houses influenced by the flow axis tend to face south. (2) The side of houses tend to be open to the outside, showing external directionality. This characteristic seems to be closely related to the direction of the main gate in a house site. (3) The layout of the main quarters and the annex quarters is found to be related to the direction of the main gate in a house site. Especially, the characteristics of courtyard are found to be affected by the annex quarters. From the above results, it can be concluded that villages have an intrinsic order depending on the geographic characteristics of a surrounding natural environment, and folk houses have also changed accordingly.

This paper tries to study systematically windows and doors frames of Taech'ung in Pyuldang in the middle period of Chosun Dynasty. The method of study is to classify the buildings in question into three forms and compare them, based on windows and doors frames in front of Taech'ung. The results are as following. First, most buildings put up windows and doors frames in front of Taech'ung and thus made Taech'ung a closed room with a wooden floor. Secondly, They put up the semi-open type of windows and doors frame in front of Taech'ung, and Yongssangch'ang(the mullioned casement window) at its back and side. Thirdly, the semi-open type of windows and doors frame in front of Taech'ung was changed into the windows of Maeng's house, Tuloyulgae-togch'ang, Shabunhapdulmun, and Shabunhapmun in sequence.

지진계수는 지진재해도 함께 지표면에서의 설계응답스펙트럼을 생성하는데 사용된다. 지진계수는 일반적으로 결정론적인 방법으로 도출되는 반면 지진재해도는 확률론적으로 계산되어 이들은 혼용될 수 없으나, 국내외 내진설계기준에서는 이들을 명확한 근거없이 혼용하고 있다. 이와 같은 근본적인 문제점을 해결하기 위해서 본 연구에서는 기존의 지진재해분석과 암반노두에서는 동일한 결과를 재현하되 지반응답해석 기능을 추가하여 토층에서의 부지증폭현상을 고려한 확률론적인 지진계수를 도출할 수 있는 新 지진재해분석 기법을 적용하였다. 新 지진재해분석 기법의 또다른 장점은 지반의 불확실성과 임의성을 합리적으로 고려할 수 있다는 점이다. 본 연구에서 계산된 확률론적 지진계수는 내진설계기준(II)과 국내에서 제안된 지진계수 세트들과 비교하여 차이점을 분석하였다. 비교 결과, 내진설계기준(II)과는 현격한 차이가 있는 반면, 또다른 지진계수와는 일부 지반분류에서만 차이가 나는 것으로 나타났다.

A solid-state conversion process for the preparation of LiNi1/3Co1/3Mn1/3O2 (NCM333) using metal oleate precursors was studied. The low melting points of metal oleate complexes result in a highly homogeneous mixture of Li-, Ni-, Co-, and Mn-oleates before calcination at a high temperature in a solid-state conversion process. The discharge capacity and capacity retention were assessed using a control sample prepared with metal acetate precursors. Cyclic voltammetry and electrochemical impedance spectroscopy showed larger cathodic and anodic peak currents and a lower charge transfer resistance for the coin cell with the cathode prepared from metal oleates than for the cell with the cathode prepared from metal acetates. The superior electrochemical properties of the NCM333 cathode prepared by the solid-state conversion process suggested in this study are attributed to the formation of a perfect R3m layered structure with a low degree of cation mixing.

This paper tries to define the characteristics of windows frame built in the end of Koryu dynasty to the early period of Chosun dynasty. The windows frame is found both in temples and in Maeng's house. It is thus proved that the frame was a general one prevailed in that time without regard to function and region. And it proves to be the original form of windows frame of temples and houses in the middle or the end of Chosun dynasty.

The ultrasonographic findings of 49 ovarian cystadenomas were analized. The results were as follows. 1. The most common age group was 3rd decade and most patients(83%) belong to active reproductive period. 2. In 80% of serous cystadenoma the size of the tumor was ranged in 6-10 cm in diameter. The large tumors of 16-20 cm in diameter were mostly mucinous cystadenomas. 3. Purely cystic appearance was the most common findigs(40%) of serous cystadenoma and thick linear septation with and without solid component was the most common findings(38%) of mucious cystadenoma. 4. Thick linerar septation with solid component was not found in serous cystadenoma. 5. Well defined nodular projection was found in 3 cases of serous cystadenoma but not identified in mucinous cystadenoma.
