Objectives : This study first acknowledges that cough, which is a light symptom, can act as a link that leads to more serious disease. With this acknowledgement, the study ponders upon how the people of the past, before the introduction of western medicine, attempted to cure the first sign of cough and how to stop it from developing. Methods : China's Eumsunjungyo and Sikgamboncho, and Chosun's Singnyochanyo and Donguibogam are used mainly to analyze the food cure that were used in relation to sea water, and to discover what types of ingredients and preparation forms were used, how they were taken, what types of food cure there were, and how they were used. Results : There was no ingredient used commonly in all of the four literatures. Eumsunjungyo utilized ingredients related to lamb. Singnyochanyo and Donguibogam were both used in Chosun, but some similarities with the Chinese literatures were discovered in terms of food cure since they were put together with their Chinese counterparts as references. Ingredients that were used commonly in two or more of the literatures were ginger, taoren, xingren, honey, pear, liyu, and pig lung. Conclusions : Some staple folk remedies that later becamce cultural cuisines included drinking the water from boiling pear and honey and boiling and eating pears with peppers stuck in them. The eating of ginger together with korean traditional taffy have taken its own form and became saenggang jeonggwa and pyeongang. The oriental food cure method has been continuing among the folk people in the form of traditional food with the food philosophy of edible homologous as its basis.

Purpose: To investigate the anticancer effects and underlying mechanisms of parthenolide on HepG2 human hepatocellular carcinoma cells. Materials and Methods: Cell viability was assessed by MTT assay and cell apoptosis through DAPI, TUNEL staining and Western blotting. Monodansylcadaverin(MDC) and AO staining were used to detect cell autophagy. Cell proliferation was assessed by Ki67 immunofluorescence staining. Results: Parthenolide induced growth inhibition in HepG2 cells. DAPI and TUNEL staining showed that parthenolide could increase the number of apoptotic nuclei, while reducing the expression of the anti-apoptotic protein Bcl-2 and elevating the expression of related proteins, like p53, Bax, cleaved caspase9 and cleaved caspase3. Parthenolide could induce autophagy in HepG2 cells and inhibited the expression of proliferation-related gene, Ki-67. Conclusions: Parthenolide can exert anti-cancer effects by inducing cell apoptosis, activating autophagy and inhibiting cell proliferation.

In this study, an uncertainty assessment for surface air temperature(T2m) and precipitation(PCP) over East Asia is carried out. The data simulated by the intergovermental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) Atmosphere-Ocean coupled general circulation Model (AOGCM) are used to assess the uncertainty. Examination of the seasonal uncertainty of T2m and PCP variabilities shows that spring-summer cold bias and fall warm bias of T2m are found over both East Asia and the Korea peninsula. In contrast, distinctly summer dry bias and winter-spring wet bias of PCP over the Korea peninsula is found. To investigate the PCP seasonal variability over East Asia, the cyclostationary empirical orthogonal function(CSEOF) analysis is employed. The CSEOF analysis can extract physical modes (spatio-temporal patterns) and their undulation (PC time series) of PCP, showing the evolution of PCP. A comparison between spatio-temporal patterns of observed and modeled PCP anomalies shows that positive PCP anomalies located in northeastern China (north of Korea) of the multi-model ensemble(MME) cannot explain properly the contribution to summer monsoon rainfalls across Korea and Japan. The uncertainty of modeled PCP indicates that there is disagreement between observed and MME anomalies. The spatio-temporal deviation of the PCP is significantly associated with lower- and upper-level circulations. In particular, lower-level moisture transports from the warm pool of the western Pacific and corresponding moisture convergence significantly contribute to summer rainfalls. These lower- and upper-level circulations physically consistent with PCP give a insight of the reason why differences between modeled and observed PCP occur.

Mongolia is a huge, landlocked, middle-Asian country bordering Russia in the north, and China in the south. Mongolia was under socialism from 1921 to 1990, and its political system has started moving toward capitalistic democratism in 1990. The history of the Mongolian Oral & Maxillofacial Surgery can be divided into four periods; the incipient period($1956{\sim}1971$), the period of early development($1971{\sim}1981$), the period of active development($1981{\sim}1991$), and the period of reformation($1991{\sim}$). Mongolian Oral & Maxillofacial Surgery had been developed by the cooperation of Soviet Union and Eastern European countries before the 1990s, but the role of Korea, Japan, and western countries has been increasing from the 1990s. In Mongolia Oral & Maxillofacial Surgery is well recognized to the people and is considered as one of the specialized medical field. There are specialized departments of Oral & Maxillofacial Surgery in State Central Hospital, Child & Maternal Research and Clinical Center, and Oncology Center in Ulaanbaatar. Now, the basic knowledge and surgical technique of the Mongolian Oral & Maxillofacial Surgeons are satisfactory. But because of the difficult social and economic situation, there is a shortage of surgical instruments and materials, and acquirement of new knowledge is not easy. In 1998 the Mongolian Association of Oral & Maxillofacial Surgeons was established and its members want to have international relationship to keep up with the new medical information. Mongolia and Korea have ethnic, linguistic and cultural similarity, so the interchange and cooperation between Mongolian and Korean Oral & Maxillofacial Surgeons are recommended to make a beautiful one-world.

We analyzed spectral attenuation of coda waves and estimated coda Q values in the crust of the Korean peninsula. 574 NS-component seismograms registered by the Korea Meteorological Administration (KMA) and Korea Institute of Geology, Mining and Materials (KIGAM) seismic networks with epicentral distances less than 100 km and sampling rate greater than 80 Hz were selected for this study. We estimated coda Q values using the single isotropic scattering model at center frequencies of 1.5, 3, 6, 9, 12, 15, and 18 Hz with 20 s time window starting from double of the S-wave arrival times. Estimated coda Q value at 1 Hz ($Q_0$) and n value range 50 to 250 and 0.5 to 1.0, respectively, and they are well correlated with the regional geology in the Korean peninsula. The $Q_0$ values in western Korea agree well with those of eastern China.

In order to investigate the regional level of air pollutants at Kangwha island situated on the western coast in Korea, the suspended particulate matter samples were collected by using the low volume air sampler on ten interval from March 1992 to February 1993 and the mass concentration of suspended particulate matter (SPM) and the chemical composition of water-soluble major ionic components in SPM samples were measured. During the sampling period, the average concentration of SPM under diameter 10 $\mu$m was found to be 48 $\mu$g/m$^3$ (+ 12). The seasonal concentration of SPM was showed in order of spring>fall>winter>summer. It was considered that higher concentration on spring than other season was affected by the long-range transport of Yellow sand particulate from China continent and lower concentration on summer by the washout and rainout effect of large rainfall. The content of water-soluble component in SPM samples was founded to be about 31% (14.69 $\mu$g/m$^3$) and 65% was unknown or unanalyzed. The content of cationic component showed in order of NH$_4^+$ (44.6%)>Na$^+$ (21.2%)>K$^+$ (14.7%)>Ca$^{2+}$ (13.6%)>Mg$^{2+}$ (5.9 %) and the content of anionic component SO$_4^{2-}$ (62.5%)>NO$_3^-$ (22.3%)>Cl$^-$ (15.2%), respectively. This fact indicates that ammonium and sulfate ion of water-soluble component in SPM sample were dominant in this region. From the chemical composition of water-soluble component, the most of Na$^+$, Mg$^{2+}$ and Cl$^-$ were originated from seawater source but K$^+$, Ca$^{2+}$ and SO$_4^{2-}$ were originated from other non-marine source. The contribution of seasalt to the composition of precipitation was 23%.

Neighboring powers in the Korean Peninsula have started to develop and operate aircraft carriers or equivalent forces to cope with rising North Korean nuclear and missile threats and also to show its national might. For example, the United States has added a aircraft carrier from the 3rd fleet to western pacific theater of operation, while Peoples Republic of China is undergoing operational test of Liaoning as well as preparing for christening of its 2nd aircraft carrier. Japan is flexing its muscle as well by deploying Izumo capable of operating F-35B to Southeast Asia to participate in multilateral exercises starting this year. It is a high time to know more about aircraft carriers or similar types in terms of maritime strategy and history. The U.S. has had by far the vast amount of experiences in utilizing aircraft carrier that it would be beneficial for us to examine U.S. perspectives and its application in the Korean Peninsula. It will provide us with insights to understand and predict what it would be like in times of crisis in the Korean Peninsula in the perspective of aircraft carrier's involvement. This paper intends to show some aspects of future conflicts in the Korean Peninsula and how the ROK Navy can best be ready for such situation. For research purpose, U.S. maritime strategy has been developed in stages ; establishment phase, WWI phase, WWII phase, Cold war phase, post Cold war phase. Each phase includes such factors as threats, strategic concept, applications, and ways to improve maritime strategy. Finally, the role of aircraft carrier based on past history as well as future conflict shines the importance to have power projection capabilities for the ROK Navy. The intrinsic nature of the navy in the world is to project power ashore just as history proved it.

The Fisher House, the first Korean Legation in the USA was located at 1513 O Street in Washington, D.C. This house was a three-story brick building with a height of 12.2m(8.84m up to the eaves) and a mansard roof. Facing the street, it is 7.32m (24 feet) wide and 23.6m(77.4 feet) depth. There is a long hallway after the entrance and a parlor with a grand fireplace next to it. This long hallway leads to a central hallway with another fireplace and a central staircase connecting the 2nd and 3rd floors. After the stairs a dining room is with a fireplace in the middle, which then leads to a pantry for dishes and the kitchen. It can also be argued that The Fisher House was the first Western-style residence for Koreans who were officially dispatched from the government. On the other hand, when living in The Fisher House, Park Jung-yang, who was sent on the three premises of the Yeonjak, directly experienced how the United States sought independence from the U.K. through the Declaration of Independence, Mount Vernon, the Washington monument, the Arlington National Cemetery, and battlefields. Even though he was summoned back to Korea by China in less than a year, Park Jung-yang actively supported the independence movement when he became acting prime minister in 1896. In this regard, The Fisher House arguably is the birthplace of Korea's independence movement.

This study aims to uncover sources of environmental learning from a student perspective using the previously unstudied case of South Korea. literature from other countries credits many sources of learning, including: media, school, personal sources, and non-governmental organizations. This analysis is based on focus group and questionnaire data collected during in-country field work. Results from South Korea are then compared with other studies carried out in the Asia-Pacific and the Western developed world. The results show that, similar to other countries including Australia, China, and India; South Korean students learn about the environment mainly through the media and schools. Television, schools, and domestic internet web pages were found to be some of the most-used sources of environmental information in South Korea, while more personal sources, such as community, family, and friends, were found to play an overall lesser instructive role. When compared internationally, South Korean students often exhibited less trust in the reliability of various sources, especially business, community, and foreign sources of information.

The purpose of this study is to compare traditional productivity and environmental productivity of Chinese 28 provinces for 1997-2005. The Eastern, the Central and the Western regions show higher M productivity indices than ML productivity indices before 2000 year, but two productivity indices of three regions report almost similar levels after 2000 year. The M productivity indices were higher than the ML productivity indices in the most provinces for 1997-2005. It implies that the Chinese regional economies have difficulties in the production activity reducing pollutants and increasing desirable outputs simultaneously. In the future, the Chinese 28 provinces need to change the direction of economic growth in the way that pursuits economic growth restraining pollution emission quantities thoroughly and should improve the concrete investment for clean technology of pollutant treatment, reinforcement of environmental regulation, and effectiveness of enforcement law.
