Roe Deer has been preserved for 25 years by the local government and the residents in Jejudo. However, the damage and harm of crops of the residents by Roe Deer are increasing as well. So, some experts worry about the unstability of ecosystem in Mt. Halla where Roe Deer live. This paper discuss the suitable number of Roe Deer population in Jejudo to protect the ecosystem in Mt. Halla and minimize the damage of residents in Jejudo. With system dynamics modeling and simulation, the population of Roe Deer at present is estimated about 2,300. However, the population of Roe Deer stays 'unstable balance'. So, a little change such as poaching and the increase of wild dogs may make the balance of ecosystem broken. According to the result of policy test simulation, we should keep on watching the poaching and maintain the number of wild dogs at about 100, so that the ecosystem in Jejudo can be stable. To reduce the moving of Roe Deer to low region, moreover, we should protect the Mt. Halla which is Roe Deer's habitat. If we are indifferent about these efforts, the ecosystem of Roe Deer in Mt. Halla will be ruined.

Cooking can be defined as the means displaying good edible foods at the table by enhancing the basic characteristics of foods through cooking and through cookery processes such as steaming, boiling, broiling, poaching, braising, roasting, frying, etc. In order to attain this goal, we have to apprehend the precise definition for the basic cooking methods and the taste. Base on this notion, this study try to show how cooking methods affect the taste and to present various cooking methods available to the characteristics of foods. Finally we hope this study will help understand how cooking methods affect the taste by analysing vaguely defined our taste into the elements having an influence on our senses of the taste.

This study analyzes how breach fee under long-term contract and/or cap regulation on the breach fee can affect the impacts of "Mobile Device Distribution Improvement Act" on handset bundle price, average revenue per unit (ARPU), and social welfare. We conduct comparative analysis with an economic model of duopoly competition in price when users are under long-term contract and the breach fee can be regulated. The results show that the Act lowers the equilibrium prices, lower than incumbent price without the Act. Price of non-dominant Mobile Network Operator (MNO) can be lower than poaching price without the Act if significant portion of switching cost is breach fee or the market is significantly asymmetric. Under the significant circumstances, the Act can raise ARPU even though it improves social welfare. By contrast, the Act increases consumer surplus without affecting social welfare if breach fee is the only source of user's switching cost and is capped by the regulation, and more symmetric market and the stronger cap leads to higher consumer surplus.

The moon bear lived in Sulak Mt. and Gili Mt. in 1949. It was reported that one bear was captured in sulak Mt. in December 19571 and the last one was killed by poacher in Sulak Mt. in May 22. 1983. Currentlyi the number of bear are decreased sharply so that Korean government designated them as their 329th natural monument in November 4. 1982. In September 2. 1997. the administration of cultural monument applied for the blood sample of bear to detection for poaching. We collected blood sample to 5 bears which are Moon bear, Malayan sun beard American black bears Ezo brown beard European brown bear. Before blood collectingl we injected to bear with Ketamine hydrochloride and Xylazine hydrochloride (10:2) to anaesthetize.

In 1749, during an incident near the Tumen River in Hunchun, six people, all Qing ginseng pickers, were killed by seven Korean soldiers from the Chosŏn garrison. The Chosŏn soldiers encountered the ginseng pickers on the border and agreed to exchange goods, but when they failed to receive the proper price for rice, the soldiers became angry and decided to attack the Qing ginseng pickers. The seven Korean criminals were executed a year and a half after the incident. The whole process regarding the arrest and investigation of the criminals, as well as the official exchanges between the Qing and Chosŏn governments, were recorded in detail in the Chosŏn document written in Chinese and the Qing documents written in Manchu. In dealing with this murder case, the Qing local officials focused on identifying the murdered victims, clarifying the victims' responsibilities, and disposing of their remaining belongings. On the other hand, the Chosŏn government focused on providing reports quickly to the Qing officials about the investigation of the criminals. In doing so, it tried to reduce the risk of any possible problems that the murder case on the border could cause in its relations with the Qing government. The relevant records on this murder case show various aspects of the Qing and Chosŏn relations, including the contacts between the people along the Tumen River, border trespassing, material exchanges, rules about ginseng picking, and border patrols. This case also reveals that the Qing and Chosŏn people from various classes had different relationships depending on their respective interests.

This paper aims at developing a System Dynamics model with an augmented predator-prey interaction structure to deal with the population management of roe deer in Jeju, Korea. Although people still regard the creature as one of the important tourist attractions, there has been much debate on the issues of the appropriateness of the population size of roe deers because they have been stigmatized as crop damagers, and roadkill/poaching victims due to their natural habit to move around from the top mountain to the lowland of the island. The model is therefore to incorporate these migrating and grazing behaviors into an augmented Lotka-Volterra model coupling roe deer population in both parts of the island to that of predators and preys of the species. The authors also provide a comprehensive set of dynamic hypotheses and relevant CLD/SFD to understand the population dynamics of roe deer and co-evolving species and perform the steady-state analysis of the proposed equation system to verify the model behavior of the numerical example lastly presented in this paper.

The number of wild animal species is gradually decreasing due to poaching, hunting and habitat loss. While several endangered animal species have been successfully preserved at the zoo, assisted reproductive technology (ART) must be applied to restore wild animals. In the case of critically endangered animals, somatic cell cloning is considered the most appropriate method of ART. Somatic cell cloning can be beneficial for the reproduction of endangered species with limited female populations. However, gene and cell banks, and understanding of reproductive physiology and optimization of ART for wild animals are urgently required for further activation of artificial reproduction of endangered species, which enlarges its application and maintains biodiversity. Care should also be taken to consider ethical and legal issues associated with somatic cell cloning for conservation of endangered animals.

Increasing of the number of Roe Deer in Jesudo is regarded as an direct cause of the damages of Roe Deer - i.e. damages of crops and trees by Roe Deer and traffic accidents between human and Roe Deer. But, no study of the number of Roe Deer in Jejudo has been found and never has been progressed it and nobody convinces about the total number of Roe Deer in Jejudo. In this paper, we focus at the moving pressure which enforces Roe Deer to move the other places. Moving pressure is appeared when the habitat environment destruction of Roe Deer and it forces Roe Deer in hilly section to move the middle mountains section and the low section. This moving pressure promotes the moving of Roe Deer to the other places and then the total number of Roe Deer in new places are increasing. High density of Roe Deer makes the habitat environment bad and increases the competition of Roe Deer. These patterns are repeated continuously. The habitat environment of Roe Deer is related with human life area very closely. We should keep and preserve our nature and environment, and if we develop our nature then we must consider our ecosystem in all aspects. It's the most important thing to us and Roe Deer and other living things.

During the late Chosun Dynasty, famine was the main cause of climate ecological background, such as frequent floods and droughts, the Little Ice Age (小氷期), and epidemic. In addition, it influenced the social and cultural background, such as failure toprovide Yiangbeop (移秧法), breakout of war and revolt, loss of farming cattle, grain consumption due to brewing, the concentration of wealth, and tenacity of shamanism. "Limwongyungjeji" "Injeji" of the last part had been written about the famine; wild plants to raw, dried, or dried powder, or processed pharmaceutical goods. Grain couldbe replaced in more than 330 types of famine relief food and recipes; 170 species of vegetables, 34 species of vegetation, and 33 kinds of fruit - the botanic foods were mainstream. Edible parts of these plant foods are those of 14 kinds: 175 species of leaves, 113 species of sprouts, 99 kinds of buds, and other fruits, roots, stems, flowers, etc. The recipe (poaching, salting, and oil-marinated) was written 186 times or forsoup, raw, and boiled.
