  • We conducted a total of 28 surveys from March to October 2016 in Gayasan National Park, to identify threatened plants for climate change, as well as for the effective management of biological organisms and resources against climate changes in Korea. Regarding threatened plants for climate change, we identified a total of 39 taxa, with 11 northern, 2 southern, and 26 taxa of concern. Among these taxa, 33 were identified as wild species. The species threatened by climate change located in the subalpine regions of Gayasan National Park were Abies holophylla Maxim., Abies koreana Wilson, Pinus koraiensis Siebold & Zucc., Betula ermanii Cham., Berberis amurensis Rupr., Rhododendron tschonoskii Maxim., Vaccinium hirtum var. koreanum (Nakai) Kitam., Primula modesta var. hannasanensis T.Yamaz., Trientalis europaea var. arctica (Fisch.) Ledeb., Thymus quinquecostatus Celak., Parasenecio firmus (Kom.) Y.L.Chen, and Lilium cernuum Kom. These species are expected to be particularly vulnerable to the effects of global warming, since they were confirmed to have a very narrow vertical distribution range. Moreover, although the following species are not included in the list of plants threatened by climate change, it is assumed that the endemic species that grow at the summit, and Grade V floristics special plants, such as Pedicularis hallaisanensis Hurus., Allium thunbergii var. deltoides (S.O.Yu, S.Lee & W.Lee) H.J.Choi & B.U.Oh, Heloniopsis tubiflora Fuse, N.S.Lee & M.N. Tamura, Aletris glabra Bureau & Franch, and Gymnadenia cucullata (L.) Rich., will also be extremely vulnerable to climate change. Therefore, we believe that measures for the conservation of these species are urgently needed, and also that the definition of species threatened by climate change should be broadened to include more objective and valid taxa through the long-term monitoring of species distributed around the summit area.

  • The maritime safety act defines a large vessel as a vessel of at least 200m in length overall. Since this standard was introduced in 1986, it has not been revised even though the marine traf ic environment has changed significantly. The length overall of 200m is equivalent to the handymax class for a dry bulker; therefore, classifying this as a modern large vessel size is difficult. Meanwhile, according to the maritime safety act, the specific sea area for traffic safety is established where large vessels frequently pass. Accordingly, by reviewing maritime-related laws, this study confirmed that standards for vessels larger than 200m in length overall were already introduced. Furthermore, by examining the statistics of vessels entering Korean ports, the existence of sea areas with a lot of traffic by large vessels, except the current 5 specific areas, was confirmed. Therefore, the following were suggested: the deletion of the term large vessel, a raise in the standard for length of a vessel related to a specific sea area in the maritime safety act.

  • This research performed tests of Video Fire Detector and criteria of installation to make suggestions regarding the criteria that must be reflected in NFSC 203 by comparing the standards of FM Approvals, UL, ISO7240 and NFPA 72. FM Standard related to Video Fire Detector test has been classified as Smoke, Flame type, but the UL Standard has classified only as a Smoke type. This research examined 6 cases of fire phenomenon detection case in ISO 7240 and 3 cases in NFPA 72, respectively. There are 15 items required for the installation standard of a Video Fire Detector and each field standard is presented as a per installation method. To apply a Video Fire Detector, the pertinent items (the definition of term, detector's classification, structure and function among its test item) must be inserted. In addition, 7 items of the fire test, i.e., the sensitivity adjustment, prevent false alarm, ambient temperature test, the effective sensitivity and detection distance and viewing angle, aging test, flood test, must be applied to the actual test. For installation in the field, the operation environment and levels of illumination, and NFSC 203 must be set, and standards relevant to the sound system, indicators' installation distance, etc. need to be inserted.

  • Using a cosmological ${\Lambda}CDM$ simulation, we analyze the differences between the widely-used spin parameters suggested by Peebles and Bullock. The dimensionless spin parameter ${\lambda}$ proposed by Peebles is theoretically well-justified but includes an annoying term, the potential energy, which cannot be directly obtained from observations and is computationally expensive to calculate in numerical simulations. The Bullock's spin parameter ${\lambda}^{\prime}$ avoids this problem assuming the isothermal density profile of a virialized halo in the Newtonian potential model. However, we find that there exists a substantial discrepancy between ${\lambda}$ and ${\lambda}^{\prime}$ depending on the adopted potential model (Newtonian or Plummer) to calculate the halo total energy and that their redshift evolutions differ to each other significantly. Therefore, we introduce a new spin parameter, ${\lambda}^{\prime\prime}$, which is simply designed to roughly recover the value of ${\lambda}$ but to use the same halo quantities as used in ${\lambda}^{\prime}$. If the Plummer potential is adopted, the ${\lambda}^{\prime\prime}$ is related to the Bullock's definition as ${\lambda}^{\prime\prime}=0.80{\times}(1+z)^{-1/12}{\lambda}^{\prime}$. Hence, the new spin parameter ${\lambda}^{\prime\prime}$ distribution becomes consistent with a log-normal distribution frequently seen for the ${\lambda}^{\prime}$ while its mean value is much closer to that of ${\lambda}$. On the other hand, in case of the Newtonian potential model, we obtain the relation of ${\lambda}^{\prime\prime}=(1+z)^{-1/8}{\lambda}^{\prime}$; there is no significant difference at z = 0 as found by others but ${\lambda}^{\prime}$ becomes more overestimated than ${\lambda}$ or ${\lambda}^{\prime\prime}$ at higher redshifts. We also investigate the dependence of halo spin parameters on halo mass and redshift. We clearly show that although the ${\lambda}^{\prime}$ for small-mass halos with $M_h$ < $2{\times}10^{12}M_{\odot}$ seems redshift independent after z = 1, all the spin parameters explored, on the whole, show a stronger correlation with the increasing halo mass at higher redshifts.

  • During these days of new understanding, western medicine has developed remarkably and a revaluation of traditional medicine has been achieved. This appears to have resulted from the sound criticisms of what western medicine has achieved up to now; excessive subdivisions of clinical medicine, severe toxicity of chemical drugs, lack of understanding about patients complaints which cannot be understood objectively, and etc. It is thought that the role of traditional medicine will be more important in the future than it is now. Someone said that the research methods of traditional medicine depends on the way of experimental science too much. That there was no consideration of a system for traditional medicine and the critic also went so far as to assert that in some cases the characteristics of eastern ideas is to permit irrationalism itself. In view of this thinking, the term traditional medicine seems to have been used somewhat too vaguely. However, traditional medicine is a medical treatment which has existed since before the appearance of modern medicine and it was formed from a traditional culture with a long history. One form of traditional medicine, oriental medicine based upon ancient Chinese medicine, was received in such countries as Korea, Japan, Thailand, Vietnam, Tibet, and Mongolia. Oriental medicine then developed in accordance with its own environment, race, national characteristics, and history. Although there are some simultaneous differences between them, three nations in Eastern Asia; Korea, Japan, and China, have especially similar features in their clinical prescriptions and medical literature. These three nations are trying to understand each others unique traditional medicines through numerous exchanges. Even though many differences in their ways of studying have developed over history exist, recent academic discussions have been made to explore new ways into oriental medicine. Therefore a comparative study of oriental medicine has gradually been thought to be more important. In Korea the formation of a new future-oriented paradigm for oriental medicine is being demanded. The purpose of the new paradigm is to create a new recognition of traditional culture which creates an understanding of oriental medicine to replace the diminished understanding of oriental medicine that was brought about by the self-denial of traditional culture in modem history and cultural collisions between oriental and occidental points of view. Therefore, to make a new paradigm for oriental medicine which is suitable for these days, and fortifies the merit of oriental medicine while compensating its defects, the author has compared the characteristics of oriental medicines in Korea, Japan, and China. The conclusions of this research are as follows: 1. The fundamental differences of the traditional medicines of these three nations are caused by the differences in the systems of Naekyung and Sanghannon. 2. The pattern-identification of illnesses is generally divided into two categories; the pattern identification of Zang-Fu and the pattern identification of prescription. 3. There are many differences in the definition of terms, such as Yin and Yang, Deficiency and Excess, and etc. 4. Chinese traditional medicine has some new concepts about pattern identification and epidemic febrile disease. 5. Japanese traditional medicine has some characteristics about pattern identification of the whole bodys condition and signs of abdominal palpation. 6. In terms of the effects of herbal drugs, Chinese traditional medicine attaches great importance to the experiential efficacy of the herb, and Japanese traditional medicine is taking a serious view of the effects of experimental medical actions.

  • Nowadays more than 200 countries are living on the earth in international relation. Having their own culture and history, these countries constitute international society, creating their national image with their own identity based on the culture and history. Though each country has cultural goods in which it combines its culture and history to economic area, the global and cultural goods representing a country is not made in short term, but completed by the combination of its long tradition, cultural consciousness of the nation and artistic level. That is to say, the image developed by the country is naturally embodied in the goods and the world recognizes the image and confirms the goods. To embody such Korean and global goods, it is essential to put priority on the research of history and culture of our society. Needless to say, it is very important to find the value of our own differentiated beauty and apply it to each area of design industry. Recognizing the differentiated value of our own cultural originality, this research performs the design of scarf and necktie to exhibit Korean image in modern and fashionable ways for commercialization by developing design of fashion and cultural goods to which Korean image is applied. Through literature and various informations, the theme of design that can best convey Korean image is determined to be the national flag of Korea, Taegeukki and five cardinal colors and the researching method is as follows. First, though the area of developing designs of cultural goods is very wide and various including commerce, industry, products , fashion, handicraft and traditional handicraft, etc., this research sets the scope of developing design, focusing on the fashion accessories utilizing the textile design such as costume, scarf, necktie and so on. Second, the definition and scope of cultural goods and the present situation of domestic cultural goods will be examined. Third, the modelling property and symbolic meaning of the national flag of Korea (Taegeultki) and five cardinal colors, the theme of design will be studied. Fourth, on the basis of above research, scarf and necktie will be designed by modern and fashionable design to which Korean image is applied. Fifth, this is textured in textile printing and gradation for commercialization.

  • This study is a conceptual analysis of Yangsaeng, which is used as a key factor for healthcare in Oriental medicine that identifies the attributes of the concept of Yangsaeng and establishes a clear definition of the term. For this, the Walker and Avant approach to conceptual analysis was employed. The antecedents included the daily routine habits required for a healthy life and reducing the risk factors in daily life by promoting physical and mental health. The results were prolonged healthy life by preventing diseases, enhanced subjective well-being, and improved quality of life. This is defined as a tool for preventing and treating diseases through positive habits in daily life and for pursuing health and quality of life. This study is a re-evaluation of existing Yangsaeng measurement tools to resolve the antecedents of Yangsaeng and proposes a need for research aimed at developing a practical, new, stand-alone tool that allows the attributes of Yangsaeng and Korean culture to be incorporated. This study is significant in that it investigates and defines the attributes that are vague and abstract and can be applied as a practical basis for nursing intervention in the nursing field at the working level.

  • Entrepreneurship is the act of being an entrepreneur or one who undertakes innovations or introducing new things, finance and business in an effort to transform innovations into economic benefits. This result in new organizations or may be part of revitalizing mature organizations in response to a perceived opportunity. The most obvious form of entrepreneurship is that of starting new businesses, or startup company. However, in recent years, the term has been extended to include social and political forms of entrepreneurial activity. Interest in the entrepreneurship education has increased significantly in now. The 61 universities made the entrepreneurship education center in the four year university and college through the government LINC program. We need the questions about the what, who and why for entrepreneurship education. Kauffman Campus Initiative(KCI) guide us to the direction of the entrepreneurship center for the future. The considerations are as follows; what is center's managerial structure, what kind of program and activities is provided, what is factors to be interested, participated in the education, how can be sustainable entrepreneurial center?. This study provide four implicit for the centers. More broad definition of entrepreneurship for the education, diverse textbook and subjects for the entrepreneurship, coach development for the teaching, and the sustainable leadership.

  • The most difficult things, when we study the future-telling science of human destiny, are in case of what one's individual's fate is bad which is shown by Saju-Palza(四柱八字), In that case, we have faced the problems on how we live ; to follow or to deny our fate under the brief of improving our lives by trying to make hard efforts, regardless of the bad Saju-Palza(四柱八字). However, we can hardly find the clear answer to those questions. 『Liao Fan 4 lessons(了凡四訓)』 shows that one's destiny can be improved by accumulating good deeds despite of the bad Saju-Palza(四柱八字). Someone says that future can be created, not be foreseen. As well, Dr. Steven Coby says that the best definite way to forecast future is in creating the future. Anyhow, the strong desire and curiosity to know one's individual's future is having been lasted until now since the Genesis. we guess these desires may be one of our basic instinct. If then, the function and role of the future-telling science will be to increase the accuracy of future prediction, whether our fate has been fixed or been able to be changeable. Therefore, this study summarizes the definition of confusing terms, focusing on Gyeokguk(格局) and Sangshin(相神), the core of Myeongrihak(命理學), which is considered to be one of the most popular future-telling science. Concering Gyeok(格), in this paper, Nae-Gyeok(內格) has been mainly considered and Oi-Gyeok(外格) or Special-Gyeok(別格) have not been addressed. Specifically, it summarized the views of the classical Myeongri(命理) books and modern scholars on Gyeokguk(格局) and Yongshin(用神). In particular, it also summarized the comparison of various concepts of Gyeokguk(格局), the advantages and disadvantages of each Nae-Gyeok(內格)'s characteristic, the determination order of Nae-Gyeok(內格) and the good case and bad case of it's Gyeok(格). In addition, it was necessary to summarize the concept of Sangshin(相神), which was talked about in 『Japyeongjinjeon』 and to briefly summarize Heeshin(喜神) with a broader concept than Sangshin(相神). The different usage of Sangshin(相神) was also analyzed, between the priority interpretation of Cheongan(天干) in Day-Column(日柱) and the interpretation based on Jijee(地支) in Month-Column(月柱). Finally, this paper was completed, leaving it later as a research task, the confusion that comes from the scholars' acceptance of the comprehensive diversity on the same term.

  • Trust is central to human relationships, at all times and places. The importance of trust is fundamental in all areas of human life, not only in the area of business administration. 2,500 years ago in China, Confucius taught that the foundation of politics was the trust of the people, more important even than military strength or the supply of food. Shakespeare's play, "Much Ado about Nothing' is about trust and deception. These days, trust and transparency in a commercial organization's business culture form the basis of the 'social capital' by which that organization increases its productivity. A successful company raises productivity by the accumulation of social capital, derived from a trust relationship between business partners, and between the company and consumers. Trust is the crucial factor. At the national level, building trust determines a nation's competitiveness. For a company, long term trust relationships with customers are essential for its survival in a business environment of rapid change. Such relationships, based on trust, are important assets to ensure a company's competitive advantage, and need to be organic to that company's business culture. Because of this importance, trust relationships have been studied in diverse areas within business administration, and especially within marketing, where they form the basis of a successful relationship between producer and consumer. However, what has been lacking is a unified definition of trust. Research has been conducted on the basis of various definitions and models. The majority of researchers have not considered the multidimensional character of the concept of trust until now. Approaches based on a one dimensional model have undermined the value of research results. Furthermore, researchers have only considered trust and trustworthiness as a single component. The majority of research has explored the consequences of perceived trust for outcomes such as loyalty or cooperation, but has neglected the effects of trustworthiness upon the mechanisms of consumer trust. This study focuses on the dimension of trust from such a perspective. It seeks to verify the effect of trust on customer intentions by breaking it down into three separate components: 1) the salesperson, 2) the product/service, and 3) the company. The purposes of this paper are as follows: Firstly, we review the multidimensional nature of trust objects: the salesperson, the product/service, and the company. Secondly, we analyze the relationship between multidimensional trust and trustworthiness. Thirdly, we analyze the connection between trust and repeat purchase intentions for the maintenance of long term relationships. For these purposes the author has developed several hypotheses as follows: H1-1: The competence of a salesperson is positively associated with the trust given by the consumer to the salesperson. H1-2: The benevolence of a salesperson is positively associated with the trust given by the consumer to the salesperson. H2-1: The competence of product/service is positively associated with the trust given by the consumer to the product/service. H2-2: The benevolence of product/service is positively associated with the trust given by the consumer to the product/service. H3-1: The reputation of a company is positively associated with the trust given by the consumer to the company. H3-2: The physical environment of a company is positively associated with the trust given by the consumer to the company. H4-1: Trust in a salesperson is positively associated with repeat purchase intentions. H4-2: Trust in a product/service is positively associated with repeat purchase intentions. H4-3: Trust in a company is positively associated with repeat purchase intentions. The data was compiled from 366 questionnaires. 500 questionnaires were collected, but some of the data was considered unsuitable and inappropriate. The subjects of the survey were male and female customers purchasing products at department stores in Seoul, Daegu and Gyeongbuk. It was carried out between Oct. 25 and 29, 2007. The data was analyzed by frequency analysis using SPSS 12.0 and structural equation modeling using LISREL 8.7. The result of the overall model analysis is as follows: Chi-Square=445.497, d.f.=185, p-value=0.0, GFI=.901, RMSEA=.0617, NNFI=.986, NFI=.981, CFI=.989, AGFI=.864, RMR=.0872. The results of the overall model analysis were coherent. It was found that trust is a multi-dimensional construct, that each of the dimensions of trust are meaningful influences on customer's repurchase intention. Trust in a company may be the most relevant, while trust in a product/service and a salesperson may be less relevant to repurchase intentions. The effective factors in determining trust in a salesperson and a company's product/service were found to be competence and benevolence. Factors in determining trust in a company were its reputation and physical environment, and the relationship of each effective trust factor has been verified in this research. As a result, it was found that competence and benevolence have a meaningful influence on trust in a salesperson and in product/service. It was also found that a company's reputation influences the overall trust in the company significantly but a company's physical environment does not have much effect.
