Luoyang Qielanji(洛陽伽藍記) is a document that describes Buddhist Temples in Luoyang, the capital of Northern Wei Dynasty. The purpose of this paper is to analyze the construction backgrounds, architectural elements and layout characteristics of Luoyang Temples in Northern Wei Dynasty. The results are as follows: The construction backgrounds of Luoyang Temples can be categorized into two types: the established-temple (創建型) and the converted-temple(捨宅爲寺型). The layout systems of Luoyang Temples can also be categorized into two main types: The front Pagoda-rear Buddhist Hall layout(前塔後殿), The front Buddhist Hall-rear Lecture Hall layout(前殿後堂). In Luoyang Temples, the pagoda was still an important element of the layout.

Thin films of CdS were prepared from an solution containing Cd(Ac)₂, NH₄OH, NH₄Ac and (NH₂)₂CS for solar cells. Growth rate of CdS films was increased with increasing temperature of reactive solution and with decreasing concentration of NH₄OH. Optical transmittances were more than 60%, independent with temperature and concentrations and was changed with thickness of CdS films. Grown films mostly showed the presence of polycrystallines with mixed cubic and hexaginal phases, but showed the hexagonal preferred phases in some growth condition. The resistivities of CdS were decreased by doping boron and criticial amount of dopant was determined.

Bang walls surround the four sides of Band in ancient capital cities of East Asia where the Bang system was in operation. There are ongoing research efforts for the structure of a capital city and Bang system around the capital of Silla, but there is a huge shortage of research on Bang walls. This study thus set out to examine Bang walls in the capital of Silla around the Hwangnyongsa Temple and its surroundings. The findings show that the Bang walls in the capital of Silla were built with a mix of earth and stone and with tiled roofs on top. The sizes of Bang walls were distinguished from the walls of individual structure groups inside Bang and closely related to the Bang size and the width of adjacent roads.

A very unique case is found in the architectural remains related to the north and south square-platform at the lecture hall site of Hwangnyongsa, that of Anyangsa, and the estimated lecture hall site of Beopsusa as they are not observed in the other lecture halls. The platform has been discovered at only those three Buddhist temples from Goryeo, and its case has not been found in ancient Buddhist temples of China and Japan. This study thus set out to investigate the north and south square-platform at lecture hall sites by examining in details its architectural remains at the three Buddhist temples and reviewing the Buddhist literature about the lecture halls of ancient Buddhist temples. Based on the findings, it was estimated that the architectural remains of north and south square-platform at the lecture hall sites of Buddhist temples were those of platform for Buddhist sermons or those of high chair platform. While the north square-platform involved the remains of north high chair for the Lecturer that gave lectures on the Buddhist scriptures, the south one did those of south high chair for the Reader who recited the Buddhist scriptures.

The purpose of this paper is to analyze the layout of Early Chinese Buddhist Temples from the Eastern Han Dynasty to the Northern and Southern Dynasties. The results are as follows: 1) In the Eastern Han Dynasty and Three Kingdoms Period, the layout of Temples was a pagoda-centered system which had one-courtyard. The layout of Temples in this period was still under the influence of Indian Temples. 2) In the Western and Eastern Jin Dynasties, the layout of Temples was still a pagoda-centered system. However, many buildings began to appear in Temples after the mid-4th century. In the Eastern Jin Dynasty, Twin pagodas started to appear in Temples. 3) In the Northern and Southern Dynasties, there were many layout types, but the main form was the layout of front Pagoda and rear Buddhist Hall. The layout of Temples in this period was in a transition stage, which evolved from a pagoda-centered Temple which had one-courtyard and after developed into a Buddhist Hall-centered Temple which had multi-courtyard.

Bell and Sutra Towers are the important elements of early Buddhist Temples. However, we still do not know the exact informations of them. So this paper studies the Bell and Sutra Towers in the Mural Paintings of Dunhuang Mogao Grottoes to find out the specific architectural form and layout of them. The results are as follows: Bell and Sutra Towers in Dunhuang Mogao Grottoes have variety of architectural types and plans, and the octagonal ‘Gak(閣)’ is the most common type of Bell and Sutra Towers. Bell and Sutra Towers are mostly located in the north side of the Temples. To be more concrete, they are located on top of the north-corridor in the Temples. With regard to the east-west layout, it seems to be that there are no fixed rules.

The “Oksa” of Samguksagi is a literature record of Unified Silla"s housing regulations according to the status system. It is considered as a very important historical record to understand the architecture of those days, and its records about the walls offer good grounds to estimate how the walls would have looked like in ancient architecture in the nation. Previous studies on the walls of “Oksa” had an interpretive issue over Yangdong (梁棟, beams and ridgepoles) and reported that there were two major types of walls with Yangdong, namely the corridor type and the palace wall type of Joseon. This study set out to review the original text of Oksa and related previous studies and consult the Chinese and Japanese literature and paintings and the wall materials of Silla architecture excavated in the Gyeongju area to provide new interpretations for the walls of Unified Silla. The findings led to the following conclusions: The walls with Yangdong over which there was a controversial issue were interpreted as “walls with an upper assembled structure of beams and purlins." Based on the records about the walls in Oksa, the study also confirmed that there were five types of walls according to the status system in Unified Silla.

Active NPC 인버터의 손실 분배 제어를 위한 뉴턴의 냉각법칙 기반의 간단한 열 모델링 기법

현승욱(Seung-Wook Hyun),이정효(Jung-Hyo Lee),원충연(Chung-Yuen Won) 한국조명·전기설비학회 2015 조명·전기설비학회논문지 Vol.29 No.9

This paper proposes a convenient thermal modeling method for loss distribution control method of 3-level Active NPC(Neutral Point Clamped) inverter. In the drawback of conventional 3-level NPC, the generated losses can occur unbalance in each switching device, as a result, thermal utilization of designed system has been decreased. In order to compensate unbalanced losses, Active NPC inverter performed loss balancing control with thermal modeling during operation of each switching device. Therefore, this paper deals with a convenient thermal modeling method based on newton’s law of cooling rather than conventional thermal modeling method. Both simulation and experimental results based on 10kW 3-level Active NPC inverter confirm the validity of the analysis performed in the study.

The corridor of ancient buddhist temples is important component part to surround main structures such as a Buddhist Hall, a Pagoda, and so forth to divide the inner space of temple. Regarding the form of the corridor, the single corridor (one bay wide) was most common, but the double corridor (two bays wide) was sometimes found from some large scaled temples. In this study, the double corridor of buddhist temples which the results of the study were insufficient up to now was researched. The formative period and form of the double corridor in ancient buddhist temples were investigated by focusing on the materials of excavation and painting for Korean, Chinese, and Japanese buddhist temples. The conclusion of the study was as follows: First, the formative period of the double corridor in ancient buddhist temples in East Asia was verified as approximately between the mid seventh century and the mid eighth century. Second, the double corridor was closely related with the enlargement of buddhist temples and the multi courtyard composition for them. Finally, the double corridor was classified as three forms depending on the position of wall, and the form that the wall is built at the center line of column was the most usual one among the three forms.
