The 21st century is the era of localization or local autonomy. It means that civil organizations or local autonomous bodies do not depend on the central government or are not controlled by it and that they are gradually expanding their scope to play independent role in the international society. In this era of globalization, local governments should build power and ability to meet the environment change actively, and should raise the services of talent who can establish proper polices suitable for the vitalization of local autonomy. Under such circumstances, this study of the Cheonan-city was aimed at arranging the problems related to the international exchanges between local autonomous governments and thereby, suggesting the reform measures to promote them. In order to analyze the condition of international exchanges, they were categorized in large into those through sisterhood relationship, human exchanges, organization status and budget scale of the international exchanges.

This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

It can be considered that the origin and development of Athletic Activities goes together with the Culture of Mankind in the wide meaning. At present, there exist about 160 countries in the world. All these countries take the policy on sports as the main principles and devote themselves to taking precedence in the formation of National physique and in the competition of International Sports. It is shown that the fundamental bloc, which currently forms the political tendency in the world, is largely brought from three types. That is to say, one is bloc of Freedom countries, another is that of Communist, and the other is, what is called, the new neutral bloc. However, the system of the most specially-compared two types is that of Freedom & Communist Bloc. This has characteristics that the former performs the policy based on the makes and executes the system upon the totalitarian and nationalistic basic idea. Also, in is not too much to say that the clear characteristics of these 2 bloc make the recent and modern age to the confrontation of idelogy, and acts the front contract through every scope in the extreme situations. Even if the Domino Circumstances as like the sinking of Communist bloc happen together with the downfall of ex. Soviet Union, we will need to understand that one of most dangerous countries in the world is North Korea and we, which confront with its line, must recognize these situations. Moreover, the South Korea and the North Korea are one Nation, but are divided by other power and authority, and it is well-known that the South Korea is threatened by the North Korea even today which half a century is approaching since our division of Nation. In these current situations, the research on part of politics, economy, society and education for the Unification will be important to us, and the person who majors in the Athletic Science performs the study on the Athletic Administration of Ex. Communist Countries and North Korea or their sports policy in the academic scope, and thus will understand their systems and the understanding how the physical educational is used to bring up any human. This purpose of this paper is to provide against the unification of the further-developed South Korea and North Korea, that is to say, demecracy and socialism, and then to support the insufficient points of each other, and then to look for the mutual union. Accordingly, we wit compare the Sports Group and Policy of South Korea and North Korea and then suggest the more-advanced development directions in this study.

Java applets are downloaded from web server through internet and executed in Java Virtual Machine of clients' browser. Before execution of java applets, JVM checks bytecode program with bytecode verifier and performs runtime tests with interpreter. However, these tests will not protect against undesirable runtime behavior of java applets, such as denial of service attack, email forging attack, URL spoofing attack, or annoying sound attack. In order to protect malicious applets, a technique used in this paper is java bytecode modification. This technique is used to restrict applet behavior or insert code appropriate to profiling or other monitoring efforts. Java byte modification is divided into two general forms, class-level modification involving subclassing non-final classes and method-level modification used when control over objects from final classes or interface. This paper showed that malicious applets are controlled by java bytecode modification using proxy server. This implementation does not require any changes in the web sever, JVM or web browser.

This study was Carried out to analyse species composition, species diversity and structure and variation trends of vegetation, of Mt. Odae, Mt. Sobaek, and Mt. Juwang following various latitudes and topographies which were in middle temperate zone in Korea. Obtained results are as follows : 1. As a result of the simple discriminant analysis, soil texture Showed the highest high percent contribution of each environmental factor to the discriminant of Studred area. And Mt. Odae showed high content of sand while Mt. Juwang Showed silt. 2. Mean stem density showed highest value in Mt. Juwang and mean D. B. H. was Mt. Odae, and on phisiographic locations showd high values of stem density and mean D. B. H in slow slope area, nothern aspect area, and high elevation area, in order. 3. Species that showed the highest importance value in each canopy-subtree-shrub layer in study area were Quercus mongolica-Acer pseudo-sieboldianum-Lindera obtusiloba were in Mt. Odae, Betula platyphylla var. japonica-Styrax obassia-Deutzia parviflora were in Mt. Sobaek, and Pinus densiflora-Acer pseudo-sieboldianum-Lindera obrusiloba were in Mt. Juwang. 4. Species that showed the highest importance value in each canopy-subtree-shrub layer on the physiographic location were Quercus mongolica-Acer pseudo-sieboldianum-Lindera obtusiloba in high elevation and southern aspect, Carpinus laxiflora-Acer pseudo-sieboldianum-Lindera obtusiloba in high elevation and southern aspect, Carpinus laxiflora-Acer pseudo-sieboldianum-Lindera obtusiloba in nothern slope, Carpinus laxiflora-Styrax obassia-Lindera obtusiloba in low elevation, and Betula platyphylla var. japonica-Styrax obassia-Deutzia parviflora in high elevation. 5. According to decrease of latitudes with going down from Mt. Odae to Mt. Juwang, the more Number of species and individuals were increased, and the deversity index was the highest value in Mt. Sobaek, the evenness was in southern aspect, and the dominance was in high elevation. 6. As a result of Cluster analysis, the study area were divided into 4 groups, Carpinus laxiflora community, Styurax obassia community, Deutzia parviflora community, and Quercus mongolica community. 7. As a result of COA analysis, communities of the study area were divided into Betula platyphylla var. japonica community, Deutzia parviflora community, Quercus mongolica-Acer pseudo-sieboldianum community, and species were divided into 4 groups as the major, the disturbed, the waterside, and the fertile. 8. As results of the simple discriminant analysis and the linear regression, sand and silt content, slope aspect, total nitrogen content, and elevation among environmental factors had high percent contribution to classification and ordination of vegetation communities of the study area. 9. Major tree species had the unstable layer structure due to lower importance values of canopies and subtrees than those of shrubs, and Pinus laxiflora and Betula platyphylla var. japonica were on the decline phase due to very low dominance and absence of next generation. while, Styrax obassia and Acer pseudo-sieboldianum were sustanable layer structure as being distributed on all the crown layer.
