Recently, it is more important to study the reasons for using media than which media is selected. This paper investigates different countries as objects to conduct the survey. In accordance with the research results, in hypothesis 1, there is a positive "(+)" influence of its interestingness, informality, restlessness, news pursuit and convenience on satisfaction when college students in South Korea use net news. Taking Chinese college students as an example, there is a positive "(+)" influence of the using motivation of net news on news pursuit, habituation, interactivity, convenience and the satisfaction with net news. In hypothesis 2, the interestingness, informality, habituation and convenience of the using motivation of online news of college students in South Korea are reflected in the acceptance intention of online news, while for Chinese college students, the informality, habituation and convenience are reflected in the acceptance intention of online news. Finally, in hypothesis 3, there is a positive "(+)" influence of the satisfaction of online news on the acceptance level of online news. In addition, this research also considers that the PLS path coefficient of college students in South Korea and China is different, and the motivations and purposes for using net news by two countries are different due to the characteristics and cultures of news media in different countries, so the satisfaction is also different.

The Strait of Malacca is one of the most important fairways in the world and its traffic safety has direct effect on economic development of East Asian countries including China, Japan and Korea. Because of this reason, a safety analysis of the marine traffic in the strait has a great significance. In this paper, we analysed the statistic distribution of marine traffic in the Strait of Malacca based on the vessels' AIS data for 1 month by using the TOAIS and EasyFit programs. As the results of the analysis, it was found that the traffic distribution of this strait was different with normal distribution, which had been still widely used in marine traffic engineering field. Furthermore, with the traffic distribution analysis results, the traffic safety of the strait was also assessed by using the IWRAP model. The results showed that the highest level of risk were overtaking and crossing situations. Finally, we found that the highest risk of collision area in the Strait of Malacca was crossing area between the Strait of Malacca and the Port Klang fairway.

The effects of electron beam (e-beam) irradiation at up to 10 kGy on the microbiological and physicochemical properties of dried red pepper powders were studied. Samples from Korea, China, and Vietnam were included in this study. In untreated samples, the total number of microbes, such as total aerobic bacteria, yeasts and molds, was in the range of $10^6-10^7CFU/g$. E-beam irradiation at 5 kGy reduced the microbial load by 2-4 log cycles, thus improving the hygienic quality of the samples. Moisture and pH of the samples were unchanged after e-beam irradiation. Reducing sugar content decreased at 1 kGy, followed by a gradual increase at higher radiation doses. At 5 kGy, no significant changes in the content of capsaicinoids were observed between the irradiated and control samples, while a 10 kGy dose led to a significant decrease. The content of pigments did not exhibit apparent changes with increasing dose of irradiation.

This paper aims to analyze how the Venture Business Tendency of North Korean refugees affects social adaptation and family health, and to provide proposals for policy making on the issue. For the purpose, we specifically suggest analysis of activation plan that 48 Venture Business North Korean managed Enterprise types, Entrepreneur type, Business type, Gender, Profit etc. As a result of analysis of actual proof, First, The Venture Business North Korean refugees managed need to consult to be technology business professionally because they features to be self-employment than expertise and knowledge basis type. Second, the rate of success of North Korean refugees is researched that female is higher than male. Third, to support Venture Business of North Korean refugees, they need one on one incubating support syspen why they are inexperienced in network, technical skills. Fourth, Venture Business Tendency of North Korean refugees affects social adaptation and family health. Since mid 1990's, North Korean refugees have come to South Korea through China or third countries due to collapsing economy of North Korea. In an effort to help those escaping from North Korea, the Seoul government provided them with a 3-month settlement program. But they have had experienced difficulties in communication, cultural assimilation, and confusion in their value system and identity. For the purpose, one-on-one interview was carried out on 45 North Korean refugees living in Seoul and neighboring cities, and the interviewed group was classified into three categories: single households, single-parent families and families with parents. The study findings demonstrated four policy alternatives to help improve quality of life of North Korean refugees and to help their successful settlemen.

Objective : The purpose of this study is to find out the possibility of application to herbal medicine's report form for adverse drug reaction (ADR) by reviewing and analyzing Asian countries's ADR report forms. Method : We investigated, compared, and analyzed ADR report forms (ADR-RF) of Asian countries's ADR institutions (ACAI), such as, Korea institute of drug safety & risk management and Dongguk university Ilsan oriental hospital (DUIOH) in Korea, national center for ADR monintoring (NCAM) in China, pharmaceuticals and medical devices agency (PMDA) in Japan, Ministry of Health and Welfare (MOHW) in Taiwan, and drug office, department of health, the government of the Hong Kong special administrative region (GHKSAR) in Hong Kong. Results : ADR-RF for ACAI included common contents, such as, patients information (name(initial), gender, age, weight), adverse event (AE)'s report information (Recognition and report for AE occurrence, first or follow up report, Severe AE), the detailed information of AE (the title of AE, onset & closing date of AE symptoms, the progress & results detailed test of AE), the information of AE's medicine (the types of medicine, product name, ingredient name, suspected or combination drug, single dose & frequency, dosage form, administration route, dealing for AE-suspected medicine), and AE reporter's information (reporter's information, institution's information). Taiwan had ADR-RF and the department exclusively for herbal medicine (HM), but others (except DUIOH) had not only no ADR report form but also contents for HM. Conclusion : ADR-RF for HM have to include the common contents of ACAI at least, as well as HM information related to ADR, such as the title, composition and types of HM, history related to HM's ADR, and the contents of drug-induced liver injury and so on. In addition, the main department of government for HM's ADR will be needed.

Background: Dust clouds blown by the wind from the arid deserts of Mongolia and Northeast China are known as Asian dust storms. Ambient particulate matter with a diameter <10 ${\mu}m$ ($PM_{10}$) is associated with the exacerbation of respiratory diseases and increased mortality of heart and lung disease patients. The fibrotic effects of $PM_{10}$ of Asian dust to pulmonary fibroblast cells are unknown. This study examined the production of reactive oxygen species (ROS), TGF-${\beta}$, NF-${\kappa}B$, PDGF-$\alpha$ and Fibronectin in fibroblasts exposed to Asian dust particles. Methods: Air samples were collected using a high volume air sampler (Sibata model HV500F) with an air flow of 500 L/min for at least 6 hours. The MRC-5 cells were exposed to 0, 50 and 100 ${\mu}g/mL$ of $PM_{10}$ for 24 hours. ROS was detected by measuring the level of oxidized DCF using FACS. TGF-$\beta$, NF-${\kappa}B$, PDGF-$\alpha$ and fibronectin were detected by western blotting. Results: There was no increase in the ROS, TGF-$\beta$ and PDGF-$\alpha$ levels in the MRC-5 cells exposed to $PM_{10}$. The NF-${\kappa}B$ level was higher in the MRC-5 cells exposed to 50 and 100 ${\mu}g/mL$ of $PM_{10}$ for 24 hours. The fibronectin level in the MRC-5 cells after 24 hours incubation with 50 ${\mu}g/mL$ $PM_{10}$ was significantly higher than the control group ($PM_{10}$ 50 ${\mu}g/mL$ 113.27${\pm}$8.65 of control, p=0.005). Conclusion: $PM_{10}$ from Asian dust increases the activation of NF-${\kappa}B$ and fibronectin expression in MRC-5 fibroblast cells.

Objectives: Nowadays, the multicultural families make up significant portion of Korean population and communities. Successful re-settling in a new country can be difficult, particularly when there are disparities in dietary behavior compared to home country. The objective of the study was to investigate the dietary behavior of marriage migrant women according to their nationality in multicultural families. Methods: The primary research was conducted targeting 94 marriage migrant women who came from China (40.4%), Vietnam (26.6%), and other countries except for Japan (33.0%). We investigated their dietary behavior, such as eating attitude and food choice behavior for Korea acculturation. We also studied dietary behavior among 14 selected subjects who had high level of integration and assimilation acculturation patterns by administering the Focus Group Interview (FGI). Results: The multicultural families had more integration acculturation patterns, which could have been influenced by their nationality. Vietnamese origin has the highest cultural adaptation as marginalization pattern. The common types of Korea acculturation were integration ($3.03{\pm}1.08$), separation ($3.10{\pm}0.59$), marginalization ($3.10{\pm}0.58$), followed by assimilation ($2.84{\pm}0.51$). There were significant differences in the four types of acculturation by marriage immigrant women's country of origin (p<0.05). According to dietary behavior, 'eliminating hunger' was the most important value in a meal. Chinese marriage migrant women, who had higher level of food intake attitude significantly, also considered 'being healthy' an important value. Regarding food choice behavior, Vietnamese had lowest frequency of homeland food intake. Most of marriage immigrant women were satisfied with the Korean food, and need for education was very high with interest for cooking, good nutrition, and managing their children's dietary life. Conclusions: Coping with a change in dietary behavior is one of the biggest transitional difficulties, and family members may need support to find their familiar food items and to continue their cultural food choice behavior in the local areas. Further researches with quantitative and qualitative analysis are needed to understand the effect of dietary behavior for acculturation in multicultural families.

Panax ginseng has been used as a typical tonic medicine in Asian countries, such as Korea, China, and Japan. It has been reported that ginsenoside Rg1 in Panax ginseng increases the proportion of T helper cells in the whole T cells and promotes IL-2 gene expression in murine splenocytes. These studies imply that ginsenoside Rg1 increases the immune activity of CD4+ T cell, however the exact mechanism of ginsenoside Rg1 on helper T cell remains to be verified. The present study tried to elucidate the direct effect of Rg1 on helper T cell s activities and its Th1/Th2 lineage development. The results demonstrated that ginsenoside Rg1 had not mitogenic effects on the unstimulated CD4+ T cell, but augmented CD4+ T cell proliferation upon activating with anti-CD3/anti-CD28 antibodies in a dose dependent manner. Rg1 also enhanced the expression of cell surface protein CD69 on CD4+ T cell. In Th0 condition, ginsenoside Rg1 increases the expression of IL-2 mRNA, and enhances the expression of IL-4 mRNA on CD4+ T cells, suggesting Rg1 prefer to induce Th2 lineage development. In addition, ginsenoside Rg1 increases IL-4 secreting CD4+ T cell under Th2 skewed condition, while decreases IFN-γ secreting cell in Th1 polarizing condition. Thus, Rg1 enhances Th2 lineage development from naive CD4+ T cell both by increasing Th2 specific cytokine secretion and by repressing Th1 specific cytokine production. Therefore, these results suggest that ginsenoside Rg1 might be desirable agent for enhancing CD4+ T cell's activity, as well as the correction of Th1 dominant pathological disorders.

The medical mineral menas a single mineral or a complex of minerals. It is natural material. using the medical action of he major or the minor elements, and traditional medicine stuff which has been used since long time ago. Jusa, cinnabar as the mineral name, is the product of the hydrothermal process. It is used to relax the body and cure high blood pressure, apoplexy and cardiopathy. Jusais the major component of "An shin hwan" and "Woo hwang chung shim hwan" nowadays because it has such an excellent calm effect. In addition, it is used to cure cancers such as esophageal cancer and gastric cancer. Jusa composed of mercuric sulfide causes mercury poisoning such as Minamata disease. It is dealt with mineralogical property and chemical composition medical stuff in Korea and China, as well asmercury poisoning and medical action of Jusa in this study. In order to predct accumulation of the interior of the body of the major and minor elements in Jusa, leaching experiment of Jusa by artificial gastric juice was done as well as thermodynamic reaction modelling to know concentration of each species of body fluid. The minor elements of 24 species such as As, Pb, Cd, a and Fe by leaching reaction of Jusa and artificial gastric juice were leached. We can know the fact that as is less than 1 ppm, Hg is less than 25 ppm and Cd and m are not detected. In addition, mercury exists as species of Hg2+, HgCl+, HgCl2, HgCl3-, HgCl42-, HgClOH, HgS(H2S)2, Hg(HS)3-, HgS22-, HgOH and Hg(OH)2 by reaction modelling between Jusa and artificial gastric juice. The concentration of sulfide complexes is 24.2 ppm and that of others is less than 10 ppm. According to increasing pH, the concentration of HgS(H2S)2, Hg(HS)3+, HgS22- and Hg(OH)2 increases, whereas the concentration of HgCl+, HgCl2, HgCl3- and HgCl42- decreases. Therefore, Jusa is very useful for the development of new medicine because it is possible to predict formation of the body species and species accumulation on mercury known as a toxic element and concentration changes of toxicity and efficiency.city and efficiency.

From the mid-1980s '91s, remarkable Ethnicism and Primitivism in the Europe fashion trend could be represented as an exotic taste longing for secenery and emotion of non-europe area in the West. These phenomenon could be found out in connection with Acculturation, which means when two different cultures or more were contacted they were identified or merged in process of diffusion and change of them. This point of view was the culture anthropologic one that make a comparison and analysis of sameness and difference between cultures. The purpose of this study was to illuminate exotic taste represented in costume in the cluture-anthroplogic aspect, to compare with beauty of costume that each culture of costume and the meaning of the times due to those differences. an aspect of the exotic taste and character in the western costume that was inspected by dividing into 'Primitivism', 'Oriental element' and 'the element of a national costume in the East European bloc ' were as follows; First, Primitivism had something in common with what was pursued in the trend of Modern Art, through the late 19th century to the early 20th century. In fashion fettered by technique, the creation expressed in a free was and showed simple beauty of costume. At the same time, pure emotion expression, creative power and witty strong expression give the cognition of transcendency breaking the routine and the cognition of complexity of an included conception. Those are garments showing not only the primitive thought and mysticism but a fancy, an abstraction, and a life. Colors and accessaries which described nature and matched simple costume composition to the expression of various material or patterns transmitted the image of the primitive strongly. Second, "Drental element" which had an effect on western custome historically in a long time had outstanding luxurios adornmental beauty of custome. Extending from the Arab stated India, China, Korea, Japan, each national costume with a gay national culture became one of motif. Various ornamental factors expressed on Trapez Line, Sime Line and Drape, or Raied style, which did not restrict the body. Those were not only functional Easy Look, but were also satisfying human's ornamental desire. Third, national factors in the East European bloc are theme that begins to be embossed in the late 80's. In view of a political change and cultural situation with a double character of Europe and Orient, it was estimated that national factors have great importance in fashion. Item concerned with new concern appeared at Autumn & Winter collection. It shows elegant and graceful beauty of costume by adding a fur or jewel to simple form. These national factors in the East European bloc are simple form, but shows the difference in more cubic formation than form expressed in Primitivism or Oriental factors Exotic taste appeared form 80's to 91's, is thought to create an forgotten romantic emotion and traditional fashion
