Background: The recent, decline in Black-berry Magnolia Vine (Schisandra repanda; BMV) native to Jeju Island, Korea, has raised concerns about the causes of this decline. We investigated the native environment of S. repanda and evaluated its propagation through cuttings to provide preliminary data for its restoration in Jeju Island. Methods and Results: The native environment of the BMV in the Hallasan National Park was surveyed and the climatic variables (temperature and humidity) were analyzed. The effects of the sex of the donor plant (male/female) type of cutting (softwood/hardwood), and treatment with a plant growth regulator (indole-3-butylic acid/rootone) on the rooting of BMV were investigated. Additinallly, the rooting rate, root count, and root length, as well as temperature and humidity were measured in the vinyl moist chambers. BMV was observed in 63 plants distributed from 567 m to 1,364 m above sea level of the Hallasan National Park. In the cutting experiment, the rooting rate was 71.9%, and it was higer in female plants (75.0%) than in male plants (68.8%). Conclusions: The mass propagation of BMV through cuttings valuable for its restoration as without such safeguard measures, the population could face extinction within a few decades.

Due to explosive expansion in R & D efforts for advancement of technological predominance by Enterprises, the volume of technical information rapidly increases and emphasize on the valuation of this information has grown ever increasingly important. Therefore the requirement for systematic management and safeguard and accumulation of these intellectual properties of the Enterprise is in very high demand. A lot of effort and research has been carried out and many on going studies in progress to try to derive the optimum solution on how to manage information retention policy, processes, execution method, and hardware to execute the information with and etc. The intent of this thesis is to recommend a way for the Enterprise on how to evaluate the valuation of the data and to suggest the method on how to manage these intellectual properties by way of using Information Lifecycle Management theory which manages data according to the business valuation of the data. The decision on valuation of data and retention cycle is based on analytic method of a nonparametric regression, experimentation was carried out by applying to Enterprise Document Management System to present the suitable retention cycle according to the valuation and variety of attribute of data.

In the past, radio astronomers have sought isolation from man-made signals by placing their telescopes in remote locations. These measures may no longer safeguard scientific observations, since NGSO satellite systems, particularly low-Earth orbit (LEO) systems, are usually designed to provide global or wide regional coverage. Further, radio astronomers have historically made their observations in the frequency bands allocated for their use by the member countries of the International Telecommunication Union (ITU). The science of radio astronomy could be adversely impacted by the deployment of large constellations of new non-geostationary orbiting (NGSO) satellites for telecommunications, navigation and Earth observation, and the proliferation of new, high-power broadcasting and telecommunication satellites in geostationary (GSO) orbits. Radio telescopes are extremely sensitive, and, in certain situations, signals from satellites can overwhelm the signals from astronomical sources. This paper describes the problem in detail and identifies ways to mitigate it without adversely affecting the continued vigorous growth of commercial space-based telecommunications.

Change of circumstances subsequent to formation of international business contract raises two issues on both parties' obligation to perform business transaction concerned. One is impossibility of performance due to events beyond control of parties and the other is adaption of contract. In Anglo-American Law such an impossibility of performance is provided by the doctrine of Frustration and the doctrine of Practicability(UCC 2-615). In practice a "force majeure" clause should be included in contract defining the parties' mutual rights and duties if certain events beyond their control occur to safeguard themselves against possible impossibility. On the other hand the tendency of international trade is that alongside sales contracts, there are contract for supplies, for furnishing raw materials, for building industrial complexes, and transferring technology. One characteristic of these agreements is their duration. For in order to carry out these agreements, it is necessary to complete a series of closely interrelated operations which, in the normal course of events, take place over a number of years. It is often difficult for the parties, when finalizing their contract, to have a full grasp of all of the factors governing their relations. With a view to resolving difficulties such as compromise the continuous performance of a contract, parties may insert a regulatory clause in their contract providing for intervention by a third person after stating in specific and detailed fashion the circumstances in which their contract may be adapted.

The objective of this study was to discuss child privacy issues at Web sites targeting children, Specifically, the study examined l)types of information required for join the membership, 2)whether privacy policies at Web sites for children abide by privacy guideline, and 3)specific examples of recommendable privacy policy and problematic privacy policy from Web sites, Total of 305 Web sites targeting children were used for content analysis, Selected Web sites included recommended sites by Korea Council of Children's Organizations and food business Web sites, The results showed that more than 70% of Web sites required private information when children join the membership. Most of these Web sites provided mailing service for children. Generally, Web sites showed problems in parents' approval procedures. Also, privacy policies at Web sites frequently omitted purpose specification principle and the security safeguard principle. Regulating online service provides and marketers targeting children would be necessary for protecting child privacy. Further, education program targeting parents and children could help them make right choices to protect children's online privacy.

This study propose a model relating supplier's use of IOIS(Inter-Organizational Information Systems) to strategic benefits through extension of Subramani's research model. In extended model, collaboration serves as a safeguard for relationship-specific intangible asset. Specifically, we evaluate how two patterns of IOIS use by supplier(exploitation and exploration) relate to two specific types of relationship-specific intangible asset(business process specificity and domain knowledge specificity), which in turn are posited to promote collaboration and strategic benefits. To explore the current study, questionnaire survey was conducted on 72 first-tier supplier firms in the manufacturing industry. Based on the survey results, we posits the following : (1) Each pattern of IOIS use directly promotes a specific type of relationship-specific intangible asset. The path of the relationship between IOIS use for exploitation and domain knowledge specificity is positive but not significant. The other paths are positive and significant. (2) Both types of relationship-specific intangible asset have a positive and significant impact on collaboration. (3) Domain knowledge specificity influences on strategic benefits but business process specificity does not have an effect on them. (4) Collaboration affects supplier's strategic benefits. These findings provide a deeper understanding of the mechanism of how the pattern of IOIS use can result in strategic benefits for supplier firms.

The purpose of this research is to find out the role of shaman's costume in Yakut Yukachir Goldi. The results are as follows: 1. Yakut shaman's costumes are decorated by their worship symbols made from metals-wild ducks crucian carps diving beetles and fishes. They believe that these costumes help shamans to travel the heaven underwater or underground systems to collect wanted infor-mation transforming them into the shape of decorated animals. 2. Yukachir shaman's costumes are decorated by symbolized cross medals in the shape of birds and human designed backbone which give shamans much power and many different kinds of medals and tassels representing all sorts and conditions of shaman's power. They consider their cstumes as feather and believe they give them new power and make them to fly anywhere they want. 3. Goldi shaman's costumes have paintings of animal guradians-leopards tigers bears birds snakes lizards and so on. Birds represents freedom of the spirit and eternity. snakes represents rebirth and immorality and lizards represents the trees of underground the earth and the lifetrees of the heaven. Shamans ascend through th holy tree to th heaven and to the world of underground in a comatose condition. Shaman costume itself plays the role of the spiritual safeguard. Wearing their costume shaman get all animal's supernatural authority and power. This makes the shaman to contact with the spirit and to travel the heaven and the under-ground world.

Recently, we reported that Jeju ground water contains vanadium components and exerts antioxidant effects in vitro and in vivo via the scavenging of reactive oxygen species and enhancement of antioxidant enzyme activities. In the present study, the antioxidant actions of Jeju ground water were compared with those of tap water against gamma-ray radiation in mice. C57BL/6 mice were irradiated with gamma-ray at a dose rate of 2 Gy. The mice were then given tap water or Jeju ground water for 90 days. Jeju ground water compared with tap water enhanced the activities and levels of superoxide dismutase, catalase, and glutathione peroxidase in irradiated liver tissues. Jeju ground water also enhanced the levels of intracellular reduced glutathione, which is vital for normal liver function and repair. These results suggest that vanadium-containing Jeju ground water can safeguard against the harmful actions of gamma-ray radiation through the support of hepatic antioxidant processes.
