The Korea railway design trends has been developed by the change of the society and culture through the consideration of the history of railway. The railway design trends is as the vehicles in the external form of railways, instantly means to plan and create the value added something like the form of the exterior design. The railway design has been changing form instinctive methods to settle the mass transport of the early days, to sensitive methods to pursue the railway culture centering around human being. As dividing by the style's change of railway in image scale aspects between 1800's and 2005 according to the life environment into the external nation, there are big differences so that is to study the development history of the railway design accordingly each nation (Korea, United Kingdom, Germany, France, Japan) and the style's change, to confirm into the design applied in society and culture needs, and to analyze by a year in changes of the environment and the railway design history. This paper analyzed railway introduced as railway models by top 4 nation (United Kingdom, Germany, France, Japan) and Korea in the past years(1800-2005) for their Korea railway design trends by image scale positioning.

본 논문은 해군 항공의 창시자이자 우리 항공의 개척자이신 조경연 선생님의 업적을 기술하였다. 조경연 선생님은 한국전쟁에 중 버려진 미군 항공기의 부품을 활용하여 다수의 수상 정찰기를 개발하였다. 또한 자신의 주도하에 개발된 항공기들을 바탕으로 해군 항공대를 창설하여 초대 대장으로서 우리 영해의 수호에 헌신하였다. 이로써 우리 해군은 스스로 개발한 항공기를 운용하는 항공부대를 갖게 되었다. 이는 대한민국 해군의 영광스러운 쾌거이자 우리 항공역사의 진정한 시발점이다.

상수 ${\varrho}$는 미분적분학뿐만 아니라 실생활에서도 중요한 의미를 갖는 상수이다. 상수 ${\varrho}$의 개념은 1618년 출판된 네이피어의 논문 부록에 처음 나온다. 그 당시의 로그의 발전이 상수 ${\varrho}$를 이해하는 데 기여하였다. 1727년에 오일러가 상수 ${\varrho}$의 기호를 도입하며 명확한 정의와 함께 상수 ${\varrho}$에 대하여 연구하였다. 현재 고등학교에서 배우는 상수 ${\varrho}$의 개념을 정립하는 데 약 100년이 걸린 것이다. 상수 ${\varrho}$의 기원의 연구를 통해 현재 우리 시대에 행해지고 있는 많은 연구가 미래에 큰 의미를 부여할 수 있기를 기대한다.

Covering an area of about 39 ha, Qingming Shanghe Park is located in the northwest of Kaifeng, formerly the capital of seven dynasties in China. It is intended to serve as a tourist attraction based on a painting 〃Qingming Festival at Riverside〃 by Zhang Zeduan of the Northern song Dynasty, which vividly illustrates a real life on the both sides of the Bian River as well as in the urban area, Kaifeng, in early Spring. The park is a collection of varied buildings such as shops, restaurants, tea-houses, theaters, and hotels in the North song style, with an introduction of the history of Kaifeng, this paper examines design philosophy and methodology of the park, and discusses the creative design of the first stage development known as known as The South Area of the park. Marked by the Rainbow Bridge and the City Gate, the South Area is divided into three parts, the rural, suburban, and urban parts which are organized according to the spatial order showed in the painting. The South Area proves to be very successful because of its amazing sense of history and interesting folk performance. Furthermore, the preliminary 9planning of the second stage development known as The North Area is presented with references to culture, history and customs. The North Area is proposed to include the Old Sports & Games Garden, the Exhibition Garden, and the Hot Spring Garden with an appearance of the imperial gardens in the Northern Song, integrated with participation of old sports and games, display of old science & technology achievements, and enjoyment of hot spring bath.

Examining how the CCP operated social services in Shanghai neighborhood[linong] in early 1950s, this article reveals the hidden relation between social service and rectification of neighborhood organizations in 1954. One of the main purpose of 1954 rectification was to guarantee provision of grassroots level of the city by recruiting local cadres, the implementers of social services. Though series of social service, such as night patrol, cleaning and public charity were indispensable for residents' life and welfare(fuli)[福利] of neighborhood, the social services was the something most of the Shanghai residents were reluctant to do. The result was the shortage of human resource for social service, triggering the "nominal position(gua ming)[掛名] " phenomenon. During political rectification of neighborhood organizations in 1954 Shanghai Municipal government tried to solve this 'decline of human resource in social services' problem by attracting the unemployed to the position of basic level cadre. To be specific, it demanded jobless person in neighborhood to be registered in time if they want a job placement. And it used that registration as the nominee of cadre in re-election process of the rectification campaign. The government measures were closely related to Shanghai people's inclination to rely on party-state when they try to get a job. Hence political rectification in neighborhood organizations become the strategic tool of city governance to mobilize residents in operating social services. So this article suggests that the CCP's urban governance was a complex and nuanced process to induce urban residents' interest and voluntarism beyond the suppression-oriented totalitarian perspective.

"역사는 거울"이라는 말은 반복되는 역사적 사실을 통해 우리는 적을 대비해야 한다는 뜻이다. 현재 우리는 북한의 핵과 미사일을 포함하는 각종 도발에 직면해 있다. 우리가 북한을 주적으로 설정하고 국민의 생명과 재산을 보전하기 위해서는 우리 군은 적의 위협에 항상 철저히 준비되어야 한다. 6.25 전쟁 전투사례를 보면 준비된 적과 무방비 상태의 국군 간에 벌어진 전쟁으로 요약할 수 있다. 북한군은 해방 이후 치밀한 계획 하에 중공군을 편입시키고 소련군 군사고문단 지원 하에 전투 장비를 배치하여 군단 급 훈련까지 마친 상태에 비해, 당시 국군은 대대급 훈련도 마무리 못한 상태였다. 전 평시 군사보안을 위해 나의 정보는 숨기고 적은 찾아서 대비해야 한다. 북한군은 전쟁을 준비하면서 치밀하게 국군의 편성과 배치, 그리고 운용사항에 대한 정보를 수집했으나 국군은 이에 대비하지 못해 초전에 고전을 면치 못했다. 이에 본고에서는 6.25 전쟁 초기, 개성일대 전투사례를 중심으로 군사보안의 교훈과 그 중요성을 제시하고자 한다.

환경변화는 생물의 성장과 번식 등의 생활사에 영향을 주며, 생물은 살아가는 서식환경에서 생태적 적합도를 가장 극대화 시킬 수 있도록 적응되어 왔다. 본 연구에서는 동적상태의존모델을 이용하여 수온과 용존산소량의 변화가 어류의 초기 성장과 체내 스트레스 누적 과정에 미치는 영향을 분석하였다. 본 연구에서 제시한 어류의 생활사 모델은 취식 행동이 성장과 체내 스트레스 누적에 영향을 받는다고 가정하였다. 또한 수온과 용존산소량의 임계점은 가장 빠른 성장속도를 유도하는 수온과 용존산소량으로 가정하였다. 이에 모델은 수온과 용존산소량의 임계점에서 성장속도가 가장 빨랐으며 임계점보다 크거나 낮은 경우 성장속도는 느렸다. 용존산소량의 저산소 상태는 체내에 누적된 스트레스양의 증가로 성장속도는 느렸고, 고산소 상태는 성장속도를 향상 시켰으나 누적된 스트레스로 신체 크기를 감소시켰다. 본 연구를 통해 환경변화가 생물에 미치는 영향을 예측하는데 있어 단일 또는 독립적인 환경요인 보다 복합적 요인들의 영향이 높음을 보였다. 따라서 환경영향평가에서 환경변화에 대한 영향 예측을 향상시키기 위하여 생리생태학적 측면에서의 복합적 환경 요인을 평가에 도입이 필요하고 또한 관련된 기법 개발에 대한 연구가 후속 되어야 한다.

The purposes of this study were to analyze and understand the life of mothers rearing children with Down syndrome and to present basic data for overcoming the difficulties of those families. For these purposes, this study made use of the phenomenological analysis and approach with a qualitative research method. The subjects of this study are 4 mothers rearing children with Down syndrome who are beyond school age. The results were as follows. First, the reason why mothers with Down syndrome children went through psychological shock and horror was the social stigma due to the unusual appearance of children with Down syndrome. Second, the isolation with in the public education system was disclosed as a factor causing much sorrow and pain. Through this, we can recognize the importance of ensuring the equal right to receive education of children with Down syndrome. Third, the period which the mother experienced most shock and confusion was right after finding out about the disability that her child has. So, we can identify the importance of early intervention providing psychotherapy and rearing service to the parents. Fourth, the crucial factor that relieved pain and pressure from mothers was social support including family. Therefore, the social support system for mothers with Down syndrome children has to be developed and strengthened. Fifth, the crucial factor that made mother grow up during rearing experience was the reestablishment of cognition about the desired role of mothers. Through this, we can identify the importance of the mental transition process to independent thinking.
