The archipelago in the southwest sea, Korea, was registered as Shinan Dadohae Biosphere Reserve by United Nations Educational, Scientific and Cultural Organization Man and the Biosphere (UNESCO MAB) on May 26, 2009. This study was conducted to determine a method of reconciling natural and anthropogenic processes and to enable sustainable development in the vicinity of the Shinan Dadohae Biosphere Reserve (SDBR). To accomplish this, the characteristics of SDBR with respect to biodiversity and cultural diversity were evaluated. In addition, a management plan regarding the wise use of the SDBR was developed while focusing on four parts: cultural support to induce motivation for native conservation and development; development and specification of fisheries and cultivation based on local community systems; restructuring of marine food products and resource transporting systems; activation and discovery of indigenous knowledge to enable networking between local residents, academia and the UNESCO-international society.

In solid-liquid two phase flow, the knowledge of how descending solid particles affected by the presence of downstream wall is important. This work studies at what interstitial distance the velocity of a vertically descending sphere is affected by a downstream wall as a consequence of wall-modified hydrodynamic forces through a validated dynamic model. This interstitial distance-the hydrodynamic coupling distance ${\delta}_c-is$ found to decay monotonically with the approach Stokes number St which compares the particle inertia to viscous drag characterized by the quasi-steady Stokes' drag. The scaling relation ${\delta}_c-St-1$ decays monotonically as literature below the value of St equal to 10. However, the faster diminishing rate is found above the threshold value from St=10-40. Furthermore, an empirical relation of ${\delta}_c-St$ shows dependence on the drop height which clearly indicates the non-negligible effect of unsteady hydrodynamic force components, namely the added mass force and the history force. Finally, we attempt a fitting relation which embedded the particle acceleration effect in the dependence of fitting constants on the diameter-scaled drop height.

Background: Smokeless tobacco consumption is one of the causes of oral cancer. The aim of this study was to determine the prevalence of smokeless tobacco consumption among male students of Zahedan universities and associated factors in 2012. Materials and Methods: In this cross-sectional study, 431 students were selected from the universities of Zahedan using multi-stage random cluster sampling. The data collection tool was a questionnaire including questions about demographic information, history of smokeless tobacco consumption, and awareness of smokeless tobacco hazards. Data were analyzed by SPSS19 using Chi-square test and multinomial logistic regression, with p<0.05 considered significant. Results: At the time of conducting this study, 102 students (23.7%) had already consumed smokeless tobacco and 49 students (11.4%) were current users (consuming at least once in 30 days before the study). There was a significant relationship between history of smokeless tobacco consumption, university/college, place of living, mean GPA, and mother's education level (p<0.05). Also there was a significant association between knowledge and prevalence of smokeless tobacco use (p<0.001). Conclusions: There is a relatively high prevalence of smokeless tobacco consumption among the male students of universities of Zahedan, which shows the need to emphasize the provision and implementation of prevention programs in universities.

21th century is a era of new pandemic. We are facing a new challenge and need a new way of approach. But eastern medicine and western medicine is clinging to their own way and have no intention to hear other one's opinion. Before the invention of the vaccination, smallpox has always been a major problem. Intellectuals in every country tried their best to find the treatment for the smallpox, and for Europian, didn't hesitate to borrow some knowledge of the pagon. Romans adopted the Galens concept, running away from the epidemic lesion. Christianity made smallpox Saints, and later adopted Razes heat therapy. But in the 17th century, these methods didn't turn out well, so they needed a new way of approach. By this movement, they had adopted the Chinese inoculation concept and invented a vaccination, By studying the effort of the Europian intellectuals who had tried their best to find the treatment for the smallpox until 17th century, we might get a glimps of wisdom which they had shown us. By this paper we can feel the passion to learn new techniques and their open mind and courage, which might be also needed in the 21th century, era of new pandemic.

This study is based on the 15th century's architecture Mohwagwan and Taepyeonggwan and the architects behind it. The results were as follows: First, inline with Ming dynasty's protocol, the King of Joseon marched with honor guard in front of his people. Therefore, the Joseon dynasty needed to match space was implemented and result in Mohwagwan and Taepyeonggwan. Second, King Taejong founded Mohwaru to share the role with Taepyeonggwan. He appropriately utilized Mohwaru as a place in manners before people enter the Seoul city wall. And He organized this architecture on the level of the palace. Third, Pak Jacheong was overseer the whole constructive process, from the selection of site, landscaping, construction, maintenance to civil engineering of Mohwaru. There are many difficulties, but he completed through the construction work owing to the protection of King Taejong. Forth, Hong Li worked with Pak Jacheong to build Taepyeonggwan and Mohwagwan from Taejong to Sejong. Supervisors in King Sejong times were required not only private capability but also understanding the Confucianism ritual. Hong Li was faithfully performed the role. Fifth, Sejong was recognized only an excellent ruler but he was also a great coordinator with a professional knowledge about architecture. These Sejong's action fully can be seen as an architect.

Objectives : This paper aims to examine the overall form of the 『Yosandangsinjipeuibangkeumnangjibo』 (『Yosandang』). Methods : The table of contents, organization of the body, citations in the 『Yosandang』 were examined, then compared to the organization of 『Donguibogam』 (『Bogam』) and 『Jejungsinpyeon』 (『Jejung』). Results & Conclusions : Based on the organization of the body, it could be determined that Byun Gwangwon referenced 『Bogam』 and 『Jejung』. However, it was found that 『Yosandang』 strived to be more faithful to the 『Bogam』 than the 『Jejung』 while it also tried to minimize the complicatedness of 『Bogam』. Its organization was unique in that it created new chapters and added contents. Also, through examination of the citations, it could be assumed that those in the 『Yosandang』 were secondary citations of the 『Bogam』 and 『Jejung』. Despite these features, it also cited the 『Zhengzhizhunsheng』 and showed efforts to include new knowledge with citation labels such as '新增[newly added]' '自述[original writing]' and 'Yosan(樂山)'. Discussion : The findings of the comparison and examination process of the organization and citations of the book revealed that the uniqueness of the organization of 『Yosandang』 is most obvious in the pediatrics chapter. This indicates that the author's intention was to deal with pediatric diseases professionally.

In the ancient times, the medical practice relied primarily upon human instincts and experiences at the same time, shaman's incantations were widely believed to cure diseases, the workings of evil spirits supposedly. For the period from the Old Chosun through Samhan(三韓), Chinese refugees brought a long medical knowledge and skills of the continent. New Chinese medicine, traditional practices and incantations were generally used at this time. In Samhan, however, the last was the most important, performed by a Chongoon(天君). Medicine and the medical system were arranged by the period of the Three Countries(三國時代). No definite record concerning Koguryo remains now. As for Paekje, however, history shows that they set up the system under the Chinese influence, assigning medical posts such as Euibaksa(醫博士, medical doctor), Chaeyaksa(採藥師, pharmacist), and Jukeumsa(呪禁師, medicine man) within Yakbu(藥部, department of medicine). Scientifically advanced, they sent experts to Japan, giving a tremendous influence on the development of the science in ancient Japan. After the unification of the three countries, Shilla(新羅) had theri own system after the model of Dang(唐). This system of the Unified Shilla was continued down to Koryo(高麗) and became the backbone of the future ones.

This study interprets the records of Bianque (醫案) as a medicine practice rather than a simple legend or story, and analyzes its effect on the development of oriental medicine. It also compares aspects of the Bianque related to patient treatment as described in 『韓非子』, 『韓詩外傳』, 『史記』, and reinterpreted using other contemporary literature. The clairvoyant power of 『史記』 「扁鵲傳」 was created by Sama-Cheon(司馬遷) exaggerating the pulse diagnosis with clairvoyance. The contents of the treatment of Sogan-Ja(趙簡子)'s confusion affairs in the first agenda, show that Bianque master the pulse diagnosis. The contents of the treatment of Kwek-Seja(虢世子)'s disease in the second agenda is a record of knowledge of acupuncture using acupuncture points. The content of refusal of treatment in the third agenda, 腠理, 肌膚, 腸胃, 骨髓 and the progression of the disease and the corresponding treatment of 湯熨, 鍼石, 火齊 are specified in detail. From the content of Bianque, he was not a martial art, but a doctor who practiced medicine, and contributed to the development of the pulse diagnosis.
