Brand switching data frequently used in market structure analysis is adequate to analyze non- durable goods, because it can capture competition between specific two brands. But brand switching data sometimes can not be used to analyze goods like automobiles having long term duration because one of main assumptions that consumer preference toward brand attributes is not changed against time can be violated. Therefore a new type of data which can precisely capture competition among durable goods is needed. Another problem of using brand switching data collected from actual purchase behavior is short of explanation why consumers consider different set of brands. Considering above problems, main purpose of this study is to analyze market structure for durable goods with consideration set. The author uses exploratory approach and latent class clustering to identify market structure based on heterogeneous consideration set among consumers. Then the relationship between some factors and consideration set formation is analyzed. Some benefits and two demographic variables - age and income - are selected as factors based on consumer behavior theory. The author analyzed USA automotive market with top 11 brands using exploratory approach and latent class clustering. 2,500 respondents are randomly selected from the total sample and used for analysis. Six models concerning market structure are established to test. Model 1 means non-structured market and model 6 means market structure composed of six sub-markets. It is exploratory approach because any hypothetical market structure is not defined. The result showed that model 1 is insufficient to fit data. It implies that USA automotive market is a structured market. Model 3 with three market structures is significant and identified as the optimal market structure in USA automotive market. Three sub markets are named as USA brands, Asian Brands, and European Brands. And it implies that country of origin effect may exist in USA automotive market. Comparison between modal classification by derived market structures and probabilistic classification by research model was conducted to test how model 3 can correctly classify respondents. The model classify 97% of respondents exactly. The result of this study is different from those of previous research. Previous research used confirmatory approach. Car type and price were chosen as criteria for market structuring and car type-price structure was revealed as the optimal structure for USA automotive market. But this research used exploratory approach without hypothetical market structures. It is not concluded yet which approach is superior. For confirmatory approach, hypothetical market structures should be established exhaustively, because the optimal market structure is selected among hypothetical structures. On the other hand, exploratory approach has a potential problem that validity for derived optimal market structure is somewhat difficult to verify. There also exist market boundary difference between this research and previous research. While previous research analyzed seven car brands, this research analyzed eleven car brands. Both researches seemed to represent entire car market, because cumulative market shares for analyzed brands exceeds 50%. But market boundary difference might affect the different results. Though both researches showed different results, it is obvious that country of origin effect among brands should be considered as important criteria to analyze USA automotive market structure. This research tried to explain heterogeneity of consideration sets among consumers using benefits and two demographic factors, sex and income. Benefit works as a key variable for consumer decision process, and also works as an important criterion in market segmentation. Three factors - trust/safety, image/fun to drive, and economy - are identified among nine benefit related measure. Then the relationship between market structures and independent variables is analyzed using multinomial regression. Independent variables are three benefit factors and two demographic factors. The result showed that all independent variables can be used to explain why there exist different market structures in USA automotive market. For example, a male consumer who perceives all benefits important and has lower income tends to consider domestic brands more than European brands. And the result also showed benefits, sex, and income have an effect to consideration set formation. Though it is generally perceived that a consumer who has higher income is likely to purchase a high priced car, it is notable that American consumers perceived benefits of domestic brands much positive regardless of income. Male consumers especially showed higher loyalty for domestic brands. Managerial implications of this research are as follow. Though implication may be confined to the USA automotive market, the effect of sex on automotive buying behavior should be analyzed. The automotive market is traditionally conceived as male consumers oriented market. But the proportion of female consumers has grown over the years in the automotive market. It is natural outcome that Volvo and Hyundai motors recently developed new cars which are targeted for women market. Secondly, the model used in this research can be applied easier than that of previous researches. Exploratory approach has many advantages except difficulty to apply for practice, because it tends to accompany with complicated model and to require various types of data. The data needed for the model in this research are a few items such as purchased brands, consideration set, some benefits, and some demographic factors and easy to collect from consumers.

Background: Bone metastasis is a single condition but presents with various patterns and severities. Skeletal-related events (SREs) deteriorate overall performance status and reduce quality of life. However, guidelines for early detection and management are limited. This study includes a survey of the prevalence of bone metastasis in cases with common cancers in Thailand as well as a focus on survival patterns and SREs. Materials and Methods: A retrospective cohort analysis was conducted using a database of the Chiang Mai Cancer Registry and the Musculoskeletal Tumor Registry of the OLARN Center, Chiang Mai University. The prevalence of bone metastasis from each type of primary cancer was noted and time-to-event analysis was performed to estimate cancer survival rates after bone metastasis. Results: There were 29,447 cases of the ten most common cancers in Thailand, accounting for 82.2% of the entire cancer registry entries during the study period. Among those cases, there were 2,263 with bone metastases, accounting for 7.68% of entries. Bone metastasis from lung, liver, breast, cervix and prostate are common in the Thai population, accounting for 83.4% of all positive cases. The median survival time of all was 6 months. Of the bone metastases, 48.9% required therapeutic intervention, including treatment of spinal cord and nerve root compression, pathological fractures, and bone pain. Conclusions: The frequency of the top five types of bone metastasis in Thailand were different from the frequencies in other countries, but corresponded to the relative prevalence of the cancers in Thailand and osteophilic properties of each cancer. The results of this study support the establishment of country specific guidelines for primary cancer identification with skeletal lesions of unknown origin. In addition, further clinical studies of the top five bone metastases should be performed to develop guidelines for optimal patient management during palliative care.

Marek(말액) is the headgear, which is a form of hempen hoods[Geon(건)] and the origin of it is Pa(파) of band form. A history book of an old Chinese country Post-Han $\ll$ History of HouHan (후한서)$\gg$ had recorded that a soldier wore a red band around his head that was called Pa(파). In the Han dynasty(한대), Pa had been transformed into Chaek(책) or a kind of a hemp rap(건) while e headgear had still remained as the band form and called Marek from e Tang era(당). The literatures of the Tang era had referred the red Marek of soldiers, and other literatures of the later period had recorded that of the previous headgears of the band form were related with Marek. Since the Tang era, white or yellow Marek except red one fer soldiers had been were by soldiers, musicians, dancers and singers in Yuan(원) and Ming(명) of China. The colors was recorded in red on documents mostly, this red implicated soldiers for symbol of terror. This fart was documented in an old history book $\ll$The history of 25 Eras(이십오사)$\gg$, On the other side, a wall painting in Princess Jeonghyo(정효공주)'s tomb of the Parhae(발해) period described the portraits of twelve persons, and among them, two Siwui(시위) put on the red Marek. Quoted from the record of a history book of the Tang era system , a history book of Three Kingdoms(삼국시대) of ancient Korea $\ll$Samguksaki(삼국사기)$\gg$ described that four dancers of Kogryo(고구려) wore Marek on their heads with the costumes of Koguryo, one of those Kingdoms. In consideration that the book of $\ll$Tongjun$\gg$ was the literature of the Tang era so that Marek mentioned in this book was followed by their name, the Marek of Koguryo dancers shown in the history book $\ll$Samguksaki(삼국사기)$\gg$ might be a kind of Koguryo style hemp cap[Geon(건)]. The Marek of Parhae had succeeded to the headgear of Koguryo and the identity was on Koguryo.

The aim of the present study was to investigate whether Bovine Spongiform Encephalopathy (BSE) is present in this country and to analyze the Global BSE Risk (GBR) status in Bangladesh. A total of 2,000 brain samples were collected from cattle older than 30 months of age, slaughtered for human consumption in the district slaughter houses from 2005 to 2006. The brainstem (obex), Pyriform lobe, cerebrum and cerebellum were subjected to histopathological study. Samples that showed some nonspecific lesions were subjected to immunohistochemistry and only brain stem to ELISA for the detection of abnormal prion protein $PrP^{sc}$. In passive surveillance, annual overall diseases of cattle, buffalo, sheep and goats in Bangladesh were collected from Department of Livestock Services (DLS), Dhaka to investigate the occurrences of neurological diseases. Import related data were collected from "National Export Promotion Bureau" Kawran Bazar, Bangladesh Bank and DLS to analyze the importing products of animal origin (cattle, buffalo, sheep and goats) from different countries to find whether or not the imported products posed any risk for the BSE. In an actire surveillance conducted in slaughter house, histopathologically BSE specific lesions were not detected in any of the brain samples, but other nonspecific lesions were observed. No $PrP^{sc}$ was detected from the samples by immunohistochemistry and ELISA. DLS report also supported the absence of BSE in cattle and buffalo and scrapie in sheep and goats in Bangladesh. It was also clearly recorded that Bangladesh imported livestock products from countries in GBR level I and II but not from countries in GBR level III and IV. From this study it apparently seems that BSE is not currently present in the indigenous animals in Bangladesh and poses no or negligible risk to human and animal health.

Objectives The purpose of this study is to help improve the management of traditional Korean medical(TKM) clinics and the policies for supporting them, by conducting a survey of the practitioners of TKM. Methods Stratified sampling was conducted based on regional location, and 700 samples were selected in a random manner from the membership list. The questionnaire was delivered and returned by mail. The survey was conducted between 20 July and 31 August 2010. A total of 177 questionnaires (recovery rate: 25.28%) were recovered and analyzed for the study. Results 1. The the survey indicate that the overall size of TKM clinics has fallen compared with previous survey, while the average number of beds per clinic has remained unchanged at 7.9. The sale of medicine as a proportion of total monthly sales has increased. 2. There has been no change in the composition of clinical staff as there are three nursing assistants. Although the average daily number of patients to clinics has remained at around 33.90 compared with ten years ago, the number of patients requiring seeking acupuncture treatment has increased while the number of those treated with medication has decreased. 3. Clinicians in TKM have indicated their preference for a binary system that separates TKM from western medicine (57.4%). The respondents do not favor the separation of dispensary from medical practice (81.5%), marks of origin for medicinal herbs (68.9%), disclosure of the prescriptions (67.2%), and the overseas expansion of Korean medical services (70.4%). However, they indicated that they are very much in favor of being granted the authority to employ and give orders to medical technicians (96.0%). 4. The respondents selected Korea as the country that maintains a proper academic system for traditional medicine (45.5%), and are not in favor of opening Korea's traditional medicine market under an Free Trade Agreement(FTA) with China (72.7%). Conclusion The overall status of the management of TKM clinics has declined compared with the preceding decade. There has been only a slight change in clinicians' opinion of the related policies and regulatory issues.

Purpose: The United States of America have pre-migration screening program are mandated through legislation. The one of purpose of this program is to prevent the importation of certain communicable diseases. Examinations of migration applicants are performed by panel physicians who are licensed physicians in the countries of origin that have agreements with the government departments of the country of destination to undertake this activity. In recent decades, the number of US migrants has increased, however COVID-19 impacted this trend of international migrants. The Aim of this study is to examine trends of US applicants and outcomes of tuberculosis and sexual transmitted infections (STIs) screening in South Korean applicants for US visa. Methods: A total of 4,442 applicants participated in US visa health check-up in 2016 to 2020. Results: The numbers of applicant for US visa in males and females was 1,814 and 2,628. The positive results in tuberculosis and STIs screening was noted with 0.66% in nontuberculous mycobacteria (NTM), 0.03% in tuberculosis, 0.03% in gonorrhea, 0.08% in syphilis, and 0.74% in chlamydia. The age groups of 2 to 14 years showed higher positive rate (13.89%) in tuberculin skin test (TST) tests compared to the rate of interferon gamma release assay (IGRA) tests (0.44%, P<0.001). The positive ratio of NTM and abnormal chest X-ray (CXR) which required sputum tests among the applicants over 15 years old has trends to increase with age. The age groups of over 70 years showed high positive rate in NTM and abnormal CXR (4.10%, 20.51%). However, ages 15 to 49 years groups showed 0.00% to 0.30% in NTM and 1.08% to 3.91% in abnormal CXR. In the study population, the positive rates of STIs were 0.03%, 0.08%, and 0.74% in gonorrhea, syphilis, and chlamydia, respectively. Among the participants who underwent sputum smears and cultures were just 1 case of active tuberculosis (0.03%) and 25 cases of NTM infection (0.66%). Conclusion: This study found that rate of positivity in tuberculosis and STIs screening among South Korean applicants for US visa in 2016 to 2020. Regarding tuberculosis, the positivity of CXR among the aged 15 to 59 years applicants was lower than that among over 60 years old. Among 2 to 14 years, positivity of IGRA was very low. And IGRA test can reduce effort of further evaluation compared to TST test in South Korea, so IGRA test among young adults can be useful. High positive rates in STI among young adult could result in high active sexuality, especially chlamydia infection is most common. Therefore Chlamydia polymerase chain reaction should be considered formal protocol among the Korean applicant for US visa.

The purpose of this study is to search for the main content system and Confucian meaning of "Yu Shu;虞書" of "The Book of Documents; 書經". This research covers two things: first, the form of The Book of Documents and the main content system of "Yu Shu". The Book of Documents consists of 4 main dynasties' Shu in ancient chinese history; "Yu Shu" 5 chapters, "Xia Shu; 夏書" 4 chapters, "Shang Shu; 商書" 17 chapters, and "Zhou Shu; 周書" 32 chapters, for a total 58 chapters. This book is organized in the form of six formalities(六體) or ten examples(十例). Second, the Confucian value of The Book of Documents and philosophical meaning of Yu Shu. Yu Shu shows a benign rule(仁政), confucianism ideal politic, as an historic example of a benevolent administration. By this research, we recognize that the tradition of abdication in the confucian society and the way of selecting people are theoretical foundation of politics based on people, rule by virtue and, by extension, a dynastic revolution. In addition, governing a country and rule the world that is treated in Yu Shu are a theory of leadership and moral training as a background of "Da Xue"(大學; Great Learning). Furthermore, Xiao(孝;filial piety) emphasized on this book is the main virtue of leaders and core value of practical action among the human relation. by extension, we recognize that the "Yu Shu" is the origin of "Xiao Jing; 孝經".

Our research task have goal to describe a treaty rhetoric known as 『La Rhétorique ou L'Art de Parler』(1688) which corresponds to a very wide field of which the step is not yet dubious in our country. Thus to study the rhetoric of Lamy borrowed from the thought of Descartes, we left the concept d' origin of language in traditional rhetoric in connection with logic and grammar (in first part). Also the second part is devoted to the tropes and the figures that are modified and deteriorated by the language of passion called 'rhetoric of passion or psychological of figure', etc. And the third part interests in the body of the speech being the character of l' heart. Under the influence of the rhetoric of Lamy, French rhetoric at the 17th century is held for an essential text when one interests in the history of the ideas and rhetoric, marked in its specificity (passion). The project of Lamy registered in the concept of passion like 'manners of speaking'. To close this study, which does one have to retain? The first remark to note is that Lamy founds his rhetoric in opposition to traditional designs dating from the beginning of Aristote. Second remark is the idea that one finds based in famous the books of Dumarsais at the 18th century and Fontanier at the 19th century. Admittedly, Lamy is a true rhetorician, grammairien which interests in the question of passions in the speech forces to reconsider the idea spread since Mr. Foucault, and makes it possible to understand the passage of the Great century at the Century of Lumuères. Even if this opinion is not shared, it will be agreed that the work of Lamy on passions or the phenomena sensory and psychological in the center of the language deserves reflexion.

Rapid changes in the flora of exotic species are ecological problems that cause the alteration of national and regional biota. The purpose of this study is to identify the reality of neophyte flora currently inhabiting in Korea. Having analyzed a total of 151 studies published up until 2016, we found the qualitative and quantitative gaps among the preceding studies due to the lack of rigorousness on the application of the spatial and temporal level of exotic species and academic terminology. In this study, the neophyte is defined as the flora introduced temporarily after the Enlightenment in Korea (late 19th century) and spatially in the Eastern Asiatic Province of the Takhtajan's floral region instead of a country boundary. A total of 326 taxa of 184 genera of 39 families were identified and analyzed for their distributional origin and habitat characteristics. Approximately 87% (285 taxa) was a component of the single-layered herb vegetation, and a total of 211 taxa originated from Europe and North America which are the same temperate biome as Korea. The wetland vegetation components were much fewer with 21 taxa, but they included a large number of invasive alien species that caused critical deterioration in the habitat structure and function of aquatic ecosystems. Ecological approaches to exotic species categories such as Ephemerophyten and Apophyten have emerged.

In the dissertation, Bibos are discussed as landscape features in the geographical context of Youngnam Region. The bibo tradition in Youngnam Region began with the incorporation of temple structures in Shilla and Kaya kingdoms, and spread throughout the country during the period of Unified Shilla. In Korea Dynasty, the diffusion of temple Bibo gained momentum, because Buddhism was worshipped as national religion. Then came a sea change in the Bibo repertoire with the replacement of Buddhism by Confucianism as an ideological prop for Chason Korea. The retreat of Buddhism led to the popularization of feng-shui motifs in Bibo strategy. The centers of the diffusion of the logic of bibo were major towns such as Kyongju, Ahndong, Sangju, and Chinju. The diffusion process continued top-down to mid-sized towns, and to the bottom of small villages. What sustained the hierarchical diffusion of Bibo attributes was myriad of transportation lines. The main artery of the diffusion in Korea Dynasty was that connecting Kaegyong to Kyongju. That same function was performed by the royal road running from Seoul through Sangju, Milyang, and to Tongrae. In the age of modernization, the feng-shui and Bibo landscapes have lost their original aura. They have suffered from the ruthless attacks of the Enlightenment logic of science. However, the elan vital of feng-shui and Bibo are still visible and strongly felt in the countryside. From field experiences, one can notice that the Bibo landscapes are tightly integrated into the rural way of life. The durability of the traditional geomancy shows us the beauty of the harmonious interplay between Youngnam people and the nature.
