Rice production in China has been rapidly increased since 1949. However, the problem of increasing production will also be left the major subject of the rice industry in China for a long time. Recently, the consumer's preference of rice is changing, they prefer japonica rice to indica rice. For that reason, the production system has been inevitably changed in all the areas of China, especially, the North of Yangze River.

We study the origin of tourism and its definitions from many points of view, and we study some relations between tourism and its similar con-cepts. We study the structures and properties of tourism, comparing the trad itional opinions and many scholars opinions in Europe. We classify the hstory of development fo tourism periodically and we clarify systematically the history of tourism in Korea from first age to sixth age in detail.

Various kinds of tourism are emerging with dynamic social and economic changes. Tourism has become an important national industry around the world and new strategies should be developed for tourism attractions to appeal tourists' psychological needs. Eco-tourism, which is an inevitable phenomenon, has been emerging as an alternative tourism. With the deregulation on outbound travel in 1990, the number of outbound travelers surpassed inbound travelers. With the IMS, it is necessary to develop a new type of tourism such as eco-tourism attracting inbound travelers. Fortunately, there are plenty of resources for eco-tourism in Korea. For example, Jindo island which has been known as the place of "Mose's miracle" is emerging as a popular tourism destination and some islands in West coast area of Korea has shown similar phenomenon to Jindo island attracting many international and domestic tourists. Also, other eco-tourism attractions such as mountains, woods, mines can facilitate inbound or demestic travel as an alternative of outbound travel to countries of Africa or of Southwest Asia. The urgent task is to preserve those natural resources, which are important for eco-tourism. In addition, it is necessary to promote existing eco-tourism attractions. In order to do that, tourists, managers, government, and environmental groups should corporate and understand each other. It is now the time for nationwide concern for eco-tourism and tourism industry, and conservation is the starting point of eco-tourism.

This paper was prepared to analyse the user's behavior patterns of the city parks in Seoul area. Thirteen parks of Seoul were selected for the analysis and computer procedure was used for the statistical method of the analysis. The behevior of users of the city parks were examined through questionaires designed to be accordant with the reference model and applicable to the standard plans or city open spaces for the future including the feasibility of the possible establishment of the model park. The outcomes dirived from the analysis can be expected to present many imlplications from the viewpoint of time-geographical extension conquored todays newly by modern civilization process, espcially the variety of city life patterns.

계면활성제 분자가 물에 녹아 구형의 회합체인 미셀(micelle)을 형성하며, 이 때의 최소 농도를 임계미셀농도(critical micelle concentration, CMC)라 한다. CMC에 영향을 준느 여러 가지 인자들 중에서 온도의 영향은 중요하며 이미 널리 연구되었다. 그렇지만, 어떤 관계가 있는지 정확한 이론이 없어서 대부분 CMC를 온도에 대한 2차 이상의 다항식으로 표현하였다. 최근에 미셀화에 따른 엔탈피와 엔트로피가 선형적으로 변한다는 보상 현상(compensation phenomena)에 대한 이해와 대부분의 계면활성제 수용액에서 미셀화의 온도에 따른 엔탈피도 선형적으로 변한다는 실험관찰이 확인되었다. 이를 근거로 열역학적 식을 사용하여 온도에 의한 CMC의 관계식을 새롭게 정립해 보았다. Micelles are one type of surfactant aggregations. They are formed above a certain concentration calle critical micelle cincentration(CMC). Micellization is affected by seveal factors, among which surfactant solution temperature is of interest in this article. It is known that CMC is dependent of temperature, but not assured how if depends on. The correlation between CMC and temperature has been represented by polynomial fitting of CMC as a function of temperature, for which relations among thermodynamic potenials, compensation phenomena, and linearity of micellization enthalpy with temperature are used.
