전호에서 히로시마에 대한 원자폭탄 1호의 투하 경위를 자세하게 알아보았다. 8월 6일에 히로시마 공격이 있은 후 사흘이 지난 8월 9일 이번에는 나가사끼에 원자폭탄이 투하 되었다. 원래 8월 11일에 참전하기로 했던 당시의 소련군이 8월 9일 나가사끼에 원폭이 투하되던 날 일본군을 전면 공격하여 참전했다. 이것은 히로시마의 원폭 투하로 전쟁이 빨리 끝날까봐 서둘러 참전한 것으로 해석되고 있다. 그러면 나가사끼의 핵공격 경과를 살펴보자.

Hiroshi Hara is one of the most famous architect in the history of contemporary Japanese architecture. During the 1970's beginning with the Awazu Residence (1972), he designed a series of symmetrical houses, the so called 'Reflection House'. All the houses in this period were based on the method of 'reflection' and 'inversion', which means a radical reversal of the accepted notion that houses are parts of cities. A concept of "A house within a house" is expanded to "A city within a house". The important spatial characteristics of 'Reflection House' are main internal core and valley-like spaces forming internal urban streets by bringing natural elements and the components of streetscape such as plaza, open space, context of street facades and so on. This procedure is called as embedding 'city' into 'house', Hara mentioned. This paper investigates the outline of the 'Reflection House' and analyses the completed works of housing that were based on the theory. Then in the final part of the paper, the implications of 'Reflection House' and its influence on his later works of following period will be discussed.

이미 작고한 중국의 자도자 등소평이 복용하여 장소를 누렸다고 하는 동충하초. 1992년 일본 히로시마에서 개최된 국제육상경기대회에서 마준렌이 이끄는 중국의 육상선수들이 신기록을 양산한 비결로 알려지면서 더욱 유명해진 버섯이다(1). 그런데 최근 국내에서 동충하초가 건강식품으로 인지도가 높아지면서 이의 판매를 둘러싸고 이해가 대립된 기관 또는 농민 집단 사이에 마찰이 발생하고, 일반 소비자는 동충하초에 관한 정확한 지식이나 정보가 없는 가운데 상인들의 상술에 농락당할 우려가 있어 자칫 건강에 유익한 새로운 식품소재에 대한 불신이 높아질 수 있는 문제가 발생하고 있다. 따라서 저자는 동충하초에 대한 모든 사람들의 이해를돕고자 그 동안 진행되어 온 상황을 설명하고 (1999년 9월까지), 여기에 내포된 문제점을 지적하였으며, 끝으로 동충하초를 국내 산업에 국한할 문제가 아니라 전세계적으로 동충하초 시장을 석권할 수 있는 발전방향과 규제완화 필요성을 제기하였다. 동충하초에 관한 일반 사항과 효능에 관하여는 저자들이 식품과학과 산업에 투고한 총설에 관련 문헌을 종합하여 요약한 바있다.

In order to get the fundamental information that could be useful to judge the potentiality of occurrence of rapid shallow landslide in the objective slope, factors selected on Jinhae regions in Korea, where many landslides were caused by heavy rainfall of daily 465 mm and hourly 52mm in August 1979, was carried out through the multiple statistics of quantification method (II) by the electronic computer. The net system with $2{\times}2cm$ unit mesh was overlayed with the contour map of scale 1:5000. 74 meshes of landslides and 119 meshes of non-landslide were sampled out to survey the state of vegetative cover and geomorphological conditions, those were divided into 6 items arid 27 categories. As a result, main factors that would lead to landslide were shown in order of vegetation, slope type, slope position, slope, aspect and numbers of stream. Particularly, coniferous forest of 10 years old, concave slope and foot of mountain were main factors making slope instability. On the contrary, coniferous forest of 20-30 years old, deciduous forest, convex slope and summit contributed to the stable against Landslide. The boundary value between two groups of existence and none of landslides was -0.123, and its prediction was 72%. It was well predicted to divide into two groups of them.

Adolf Loos and Hiroshi Hara are very well known for their distinctive method of spatial composition. Adolf Loos showed white silent outer facades from his strong aversion to the ornament, whereas dynamic and rich inner space by the principle called 'Raumplan' in his housing design. Hiroshi Hara, one of the most influential architects in modern Japanese architectural history, designed a series of controversial houses with radical design by his 'Yukotai Theory' and the thought of 'Reflection House'. Even they have no common in regional background or the period of their works, both similarly have shown their own focus on cladding surface as an important design language. From this point of view, this paper investigates the design method of those two architects focused on the similar points and also the differences of their approaches to cladding in housing design. In conclusion, in case of Adolf Loos, the cladding is a tool to create completely safe and pure inner space by separating from the outside. On the other hand, the cladding of Hiroshi Hara has the meaning of social ideology that individuals must follow the principles of a dominant structure, which is the reason why the cladding should be removed. However there exists something in common also. They radically denied the outer circumstances and had a firm belief that the requests from the inside living space were the more influential factors.

배경 및 목적 : 한국 구개열환자에게는 된소리 자음(농음0의 구음산출의 난도가 높다는 것은 임상적으로 잘 알려져 있다. 그러므로 본 연구에서는 한국 구개열 환자에게 있어서 난도가 높은 농음의 산출 메커니즘의 기본적 요소를 규명하므로서 언어치료의 새로운 방법모색에 기여하고져 하였다. 연구방법; 비강자음에 후속된 3종의 어두 파열자음 산출시의 구개범거근의 근활동 양상의 차이를 비교검토하므로서 농음의 산출특성을 검색하고져 하였다. 관찰기록 방법은 근전도는 유구침금전극(hooked wire electrodes)을 구강내로부터 경점막적으로 유도하였다. 연구결과 : 격음과 농음의 파열자음에서 평음보다 높은 구개범거근의 근활동이 관찰되었으나 격음과 농음 사이에선 유의미적인 차이는 보이지 않았다. 결 론 : 금후의 과제로는 피험자를 늘려 재확인을 하는 일, 및 농음과 격음의 변별요소에 관해 더욱 검토할 필요가 있는 것이 시사되었다.

As well as "Sangyeongpyo," "Gogyeong-Jeongripyo," table of national road transportation system is important to comprehend identity of national geography in Joseon era even if it had not been researched yet. The aim of this study is to divide type of these tables and find its genealogy through mainly analyzing the road network and land names. As the result of this research, "Yeojigo," topographical researches of Korea, edited by Shin Gyeong-Jun as a palt of "Dongguk-Munheonbigo" official book in natural history of the Joseon Dynasty published in 1770, might be identified as the origin for all copy of "Gogyeong-Jeongripyo." Then "Gogyeong-Jeongripyo," can be divided into at least three major types; almost direct descent of "Yeoji go" as 'type1', minor modification as 'type2', and hybrid edition(type3) with second type that quoted many land names as route information from "Dorogo," another topography specialized for road transportation. Since "Dorogo" was also composed by Shin, after all, all genealogy of "Gogyeong-Jeongripyo" came from him.

This essay is discusses the phase on expression as experimental animation for the tendency of the animation which appeared newly 1960s in Japan by "3 members in animation". In general, experimental animation is contrary to traditional animation. "3 members in animation" tried to present the concept of animation newly with the various trials which overthrow the form of the conventional animated cartoon. Those days, the feature animation of Toei was the mainstream of the cartoon film. When comparing with Yoji Kuri's works, the movement and theme on expression are different. It can be said that the difference is an alternative method to the mainstream. Other members Ryohei Yanagihara and Hiroshi Manabe connected design and illustration with animation. The independent creators participated in the animation festival which "3 members in animation" held. They tried to create animation interchanging with other genres. It can be said that the intermediality seen in their work is trial which sets variegated the object of animation and it expands the possibility of the new animation. Their approach overthrew the traditional tendency and was able to call it experimental animation. Japanese experimental animation in 1960s is the historical starting point of recent independent animation which searched for art in which an original expression has been formed in Japan.

In this work, the in-situ viscoelastic characteristics of electropolymerized polypyrrole (PPy) thin film were investigated in the electrolyte solutions of $NaClO_4$, $LiClO_4$, and $KClO_4$ by using quartz crystal analyzer (QCA). One side of quartz crystal was used as a working electrode mounted in a special fabricated QCA electrochemical ceil. The resonant frequency and resonant resistance diagram (F-R diagram) was used to interpret the viscoelastic characteristics of Pby thin film and compared with AFM photograph. The resonant frequency, resonant resistance, and current were measured to analyze the redox reaction behaviors when the cyclic voltammetry was performed using AT-cut quartz crystal electrode coated with galvanostatically polymerized Ppy film. The result suggests that the Ppy film polymerized onto the crystal behaves as a rigid elastic layer at the initial stage of electropolymerization, while the film becomes a viscoelastic layer the polymerization proceeds further. At the same time, the film thickness increases and some morphological changes take place due to the penetration of electrolyte solution into the film. These phenomena take place when cyclic voltammetry was performed using different electrolyte solution compared with polymerization process.
