  • This research traces the history of legislative matters regarding the enactment and revision of laws and regulations related to the outdoor landscape in apartment complex. The years before 1976 can be classified as 'a period of darkness' for the landscape in apartment complex due to absence of landscape legislation. From the year of 1977 when the landscape planting and mere necessities were carried out according to the local administration's building standard to the year of 1990 can be classified as 'a period of quickening'. The year of after 1991 when the enactment of the code#32 called "the green space in site" in the "Korea Building Code" and the "Korea Housing Standard & Regulation" was made, and various construction regulations and provisions were revised in order to improve the scantiness of the apartment complex and its environment should be called 'a period of development'.

  • Dysuria has been mentioned several times in "Treatise on cold" and "Golden Chamber" of Zhang Zhong-jing in Han Dynasty. This article makes a detailed discussion of etiology, pathogenesis, treatment and prescription of Dysuria from three periods that is Han and Tang Dynasty, Song and Yuan Dynasty, Ming and Qing Dynasty. It has demonstrated the inheritance, development and innovation of academic ideas of later physicians from Zhang Zhong-jing, which enriched and developed the theory of Zhong-jing.

  • This study presents a method to predict plant-specific and operational history dependent scaling factors. Realistic and detailed approaches are taken to find scaling factors at reactor coolant. This approach begins with fission product release mechanisms and fundamental release properties of fuel-source nuclide such as fission product and transuranic nuclide. Scaling factors at various waste streams are derived from the predicted reactor coolant scaling factors with the use of radionuclide retention and build up model. This model makes use of radioactive material balance within the radioactive waste processing systems. According to input parameters of plant operation history, scaling factors predicted at reactor coolant and waste streams are well brought out the effects of plant operation history.

  • The many cities are changing in the city form where the person and nature are mixed. Namely, the government invests many expense in tree field of distance space for the change in the green city. In this paper, we design and implement a tree growth management system using PDA built in 13.56MHz RFID reader and CBD(Component Based Development) for ubiquitous computing environments. Our system provides history management to increase business efficiency for location coordinate of tree and history information of tree which using RFID, the RFlD tag is attaching the new tree and that is inputting GPS location information in PDA and provides tree information of tree by location coordinate to history management. Finally, we show from a performance analysis that our system achieves about 85% average tree read rate of RFID under test scenario environments.

  • 최근 가상현실을 활용한 문화유산 콘텐츠들이 활성화되고 있다. 그러나 그 대부분은 증강현실이나 가상현실을 통해 단순 복원정보나 고증정보를 제공하는 데 그치고 있다. 이글에서는 메타버스의 4가지 유형을 통해 역사교육콘텐츠 개발방안을 살펴보았다. 첫째, 가상세계의 구현을 통해 학생들이 과거 신분별 아바타를 운영해 봄으로써 당시 생활을 체험해 볼 수 있다. 둘째, 증강현실을 통해 현재 체험해 볼 수 없는 사건이나 문화유산의 현장을 경험할 수 있다. 셋째, 시간의 흐름에 따른 사회의 변화를 거울세계를 통해 확인할 수 있다. 넷째, 라이프로깅을 통해 사물의 용도와 주사용자 등 다양한 삶의 방식들을 이해할 수 있다. 이러한 4가지 유형은 사례에 따라서 상호 결합해서 적용할 수 있다. 디지털 시대 역사교육은 단순 정보 전달에 그쳐서는 안된다. 다양한 경험의 확장을 통해 역사상을 제대로 이해할 수 있도록 해야 한다.

  • In this study, in regard to concrete considering variety of admixture content rate, we evaluated property of adiabatic temperature rise. By setting up high temperature history, we evaluated effect to compression strength property of high strength concrete by early high temperature history. As a result, early high temperature history accelerated Hydration reaction of cement and contribute early strength development but it didn't accomplish performance objective in long-term aged.

  • In this paper, our main concern is the historical development of the Finsler geometry in Debrecen, Hungary initiated by L. Berwald. First we look into the research trend in Berwald's days affected by the $G{\ddot{o}}ttingen$ mathematicians from C. Gauss and downward. Then we study how he was motivated to concentrate on the then completely new research area, Finsler geometry. Finally we examine the course of establishing Hungarian Debrecen school of Finsler geometry via the scholars including O. Varga, A. $Rapcs{\acute{a}}k$, L. $Tam{\acute{a}}ssy$ all deeply affected by Berwald after his settlement in Debrecen, Hungary.

  • Urban pollution has been a problem in China since ancient times. In modern times, pollution was aggravated by industrialization and urbanization and became closely related to people's lives. Shanghai was the industrial center and the most urbanized place of modern China. As a price, it needed to face extremely serious urban pollution, and the treatment of this problem involved all aspects of social life. Noise pollution let foreigners to interpret the Chinese people and the city of Shanghai from a cultural perspective, and let Chinese residents to understand Shanghai and the nation from a civilized perspective. Pollution regulation made Shanghai the first city in modern China to implement overall pollution control and levy environmental protection fees. It also enabled the Chinese to gradually fight for their rights in urban governance. Urban pollution also brought business opportunities; in the highly commercial city of Shanghai, it promoted the development of some industries. The experience of urban pollution and its treatment prompted the people of Shanghai to rethink and re-recognize modern civilization, and also promoted the formation of Shanghai urban community.
