Purpose : The purpose of this study was to investigate the clinical features of adolescent TB. Methods : We retrospectively reviewed the medical records of the adolescents aged 12 to 18 years and who are hospitalized with the diagnosis of TB at Dong Kang General Hospital between January 2003 and December 2007. Results : Of the 29 patients who were identified, 65.5% were male. The median age at diagnosis was 16.9 years (range: 12.1-18.9 years). A tuberculin skin test (TST) was performed for 6 patients (20.7%). Among them, 5 (5 of 8[62.5%]) in the 12-15 years age group (Group A) and 1 (1 of 21[4.8%]) in the 16-18 years of age group (Group B) were TST positive, which showed that the TST performing rate decreased with age (P<0.01). Twenty-five patients (86.2%) were detected by evaluating the clinical symptoms that suggested TB and 4 patients (13.8%) were detected by screening, but no cases were detected by contact tracing. Twenty patients (69.0%) had isolated pulmonary disease. Seven patients (24.1%) had pulmonary and extrapulmonary disease and 2 patients (6.9%) had exclusively extrapulmonary disease. Most patients presented with multiple symptoms, and the most common were cough (79.3%), fever (75.9%), sputum (65.8%) and chest pain (34.5%). M. tuberculosis was isolated from the sputum of 20 patients (69.0%). The culture-positive rate increased with age (range: 62.5% in Group A to 71.4% in Group B), but the difference between the groups was not significant. Cavitary lesions were found 13 patients (44.8%). The cavitary lesion rate increased with age (range: 25.0% in Group A to 52.4% in Group B), but the difference between the groups was not significant. Four patients (13.8%) were lost during follow-up. One patient (6.9%) relapsed. Conclusion : Clinicians need to be aware of the unique features of adolescent TB, and they also need awareness of the importance of TST and contact investigation for an adult suspected of having TB for making the diagnosis of TB.

Until early 1980s we have lived without thinking that radon ruins our health. But, scientists knew truth that radon radioactive danger is bedeviling on indoor that we live for a long time. Specially, interest about effect that get in danger and injury for Radon and human body is inactive in our country. Recently, with awareness for Radon contamination, We inform about importance and danger of Radon in some station of the Seoul subway, indoor air of school facilities and We had interest with measure and manages. Usually, Radon gas emitted in base of building enters into indoor through building floor split windage back among radon or indoor air of radon daughter nucleus contamination is increased. Therefore, indoor radon concentration rises as there are a lot of windages between number pipe of top and bottom and base that enter crack from estrangement of the done building floor, underground to indoor. Thus, Radon enters into indoor through architecture resources water as well as, kitchen natural gas for choice etc., but more than about 85% from earth's crust emit. Danger and injury of health by Radon and Radon daughter nucleus that is indicated for cause of lung cancer incerases content of uranium of soil rises specially from inside pit of High area and a mine, cave, hermetical space with house. Safe sub-officer of radon concentration can not know and danger always exists large or small during. So, Important thing reduces danger of lung cancer by lowering concentration of Radon within house and building. Therefore, is thought that need general house Radon concentration measurement, measured Radon concentration monthly using Sintillator radon monitor. Study finding appeared high all underground market 1 year than the ground, and the winter appeared high than the summer. Specially, month that pass over 4pCi in house that United States Environmental Protection Agency advises appeared in underground, and appeared and know Radon exposure gravity by 4 months during 12 months. Therefore, Thinking that establishment and regulation of norm and preparation of reduction countermeasure about Radon are pressing feels, and inform result that measure Radon concentration.

Objectives : Since the awareness of autism spectrum disorders(ASD) is growing, as a result, it is increasing numbers of infants and toddlers being referred to specialized clinics for a differential diagnosis and the importance of early autism spectrum disorders detection is emphasized. This study is to know the difference between ASD and intellectual disability(ID) from comparison of the demographics, clinical characters and obstetric complications. Methods : The participants are 816 toddlers who visited the developmental delay clinic(DDC) in National Health Insurance Ilsan hospital. The number of toddlers diagnosed as ASD and ID was 324 and 492. 75 toddlers out of 114 who returned to DDC were diagnosed as ID at the first visit but 7 of them had changed diagnosis to ASD at the second visit. After compared ASD with ID from the first visit, we analyzed characters of toddlers who had the changed diagnosis to ASD at the second visit. Results : As a result, the comparison between ASD and ID at the first visit shows that the boys have higher ratio, lower obstetric complication and lower language assessment score in ASD. The toddlers who had the changed diagnosis at the second visit were all boys and they had more cases of family history of developmental delay and had lower score of receptive language developmental quotient. Conclusions : These findings suggest that sex, language characteristics and obstetric complication could be useful in the early detection of ASD.

This survey was conducted to assess the consumer perceptions of food-related hazard in 500 housewives from all over Korea. The subjects were selected by stratified random sampling method. The survey was performed using structured questionnaire through telephone interview by skilled interviewers. The results showed that 34.6% of the respondents felt secure and were not concerned about food safety, and 65.4% were concerned about food safety. Logistic regression analysis showed that the increasing concern on food brands, food additives (such as food preservatives and artificial color), and imported foodstuffs indicated the current increasing concern on food safety. Other related factors indicating the increasing concern on food safety were education level and care for children's health. The respondents who cared about food safety expressed a high degree of concern on processed foodstuffs such as commercial boxed lunch (93.3%), imported foods (92.7%), fastfoods (89.9%), processed meat products (88.7%), dining out (85.6%), cannery and frozen foods (83.5%), and instant foods (82.0%). The lowest degree of concern was on rice. All the respondents perceived that residues of chemical substances such as pesticides and food additives, and endocrine disrupters were the most potential food risk factors, followed by food-borne pathogens, and GMOs (Genetically Modified Organisms). However, these results were not consistent with scientific judgment. Therefore, more education and information were needed for consumers' awareness of facts and myths about food safety. In addition, the results showed that consumers put lower trust in food products information such as food labels, cultivation methods (organic or not), quality labels, and the place of origin. Nevertheless, the respondents expressed their desire to overcome alienation, and recognized the importance of knowing of the origin or the producers of food. They identified that people who need to take extreme precautions on food contamination were the producers, government officials, food companies, consumers, the consumer's association, and marketers, arranged in the order of highest to lowest. They also believed that the production stage of agriculture was the most important step for improving the level of food safety Therefore, the results indicated that there is a need to introduce safety systems in the production of agricultural products, as follows: Good Agricultural Practice (GAP), Hazard Analysis and Critical Control Point (HACCP), and Traceability System (75).

In Korea and the Philippines, as well as all over the world, with the recognition of the importance of marine ecological resources, the marine protected areas(MPA) have been established and managed to protect and preserve these resources. While the number of marine protected areas for marine ecological resources protection has been increased, there is main problem that the most of MPAs do not achieve their intended management objectives. the effective management. Because of the positive and negative impacts on local communities and fishermen as direct stockholders, there has been ongoing debate on the pros and cons of implementing MPAs. Accordingly, this research conducted a case study of establishing Marine Protected Areas in Guimaras, Philippines because Philippines fisheries code of 1998 (Republic Act 8550), which is enacted to manage, conserve and protect fishery resources, obliged local governments to designate no less than 15% of jurisdictional municipal water as fisheries resource protection areas for a long time. To do this, a dichotomous-choice contingent-valuation survey was conducted in the two municipalities of Guimaras, Philippines to investigate public opinion in debates over MPAs and to estimate willingness to pay (WTP) for MPAs to protect and conserve marine habitats for fishery resources. Because of the expected economic costs by prohibiting fishing activities within the establishing newMPA, 58.7% of respondents thought the costs should be compensated, but 91.4% respondents voted in favor of increasing MPAs for fisheries resources as a protective measure. Finally, with Contingent Valuation Method(CVM), the aggregate mean WTP (375.5ha) of San Lorenzo and Sibunag residents in Guimaras Province, Philippines for establishing the additional MPA in their municipality waters was estimated to $1,046,791. Therefore, these findings could be used as a valuable data for establishing effective management plan of MPAs in Korea.

This study is a development plan of a resort in a regional center that aims to generate tourism consumptions that have ripple effects on the regional economy by developing abandoned mine complexes in Daechon. Thanks to economic growth, the public awareness of tourism has changed. Hence, want for tourism influences development and advancement of recreational spaces, combining with various cultural contents. Development associated with environmental issues caused by modernization has become a major issue. At this point, to rediscover and specialize industrial complexes of bygone days as tourism resources signifies regeneration of regional resources. This study aims to find a solution for appropriate tourism development as part of the measures to revitalize the regional economy in underdeveloped areas and to improve the polluted environment. The result of the study is summarized as follows: First, in regional development alongside the development of a resort complex, it is important to construct environmental similarities. Minimizing differences in landscape structures is especially necessary because it will cause tourism resources in a regional center to be naturally linked to regional activities. These will then be recognized as attractions in the neighborhood. Therefore, it is desirable to reflect a spatial structure for environmental convergence, and, at the same time, to fulfill operation purposes by space through differentiation of movement lines. Second, in utilization of existing environmental resources, it is desirable to express localities and to develop differentiated elements. Facilities should not be homogenized, attaching importance to trends. Therefore, in establishing a development plan, it is important to have an attitude to accept existing roles and functions in a transformative manner. Third, recreational facilities in resort spaces generally have the problems of being uniformly planned as part of a development project and being limited to landscape facilities. Introduction of specialized facilities that can be reconciled with the regional environment and that can be open influences the landscape structure of the entire region and brings ripple effects as key facilities for activation of tourism.

The purpose of this study was to investigate the factors affecting dentists' attitudes and dental hygienists' services on dental anxiety in adults. The subjects were 300 adults older than 20 years of age living in Seoul, Gyeonggi, Daejeon, and Daegu. Data were collected using structured questionnaires. Among the distributed questionnaires, 225 respondents were selected as subjects, excluding 74 people who did not answer and 1 person who was not faithful. Data were analyzed using statistical software with a t-test, one-way ANOVA, and multiple regression. As a result, the gender was slightly higher in women (54.7%) than in men, and the last dental visit was less than one year in 59.6% of respondents. Most of the respondents' educational level was higher than college level (79.1%), and the monthly income was less than 2 million won in 53.8 of respondents. This study showed that distrust of dentists affected dental anxiety and anxiety stimulation. Higher reliability of the dentist was correlated with less dental anxiety in patients. Dental anxiety showed statistically significant results in dentist subcategories of patient slight and dentists' trust (p<0.01). Additionally, the factors affecting dental anxiety and anxiety stimulus were knowledge of dental hygienist and distrust of dentist (p<0.01). According to this study, dentists' and dental hygienists' trust of dental staff show the importance of oral health professionals' role in reducing dental anxiety in patients. It is also suggested that efforts should be made to improve public awareness of oral health experts. It is believed that dentists, and dental hygienists need to promoted to become professionals. In addition, a variety of programs have been developed to reduce dental anxiety, so patients need to be comfortable to receive dental treatment.

Collaboration strategies entail information sharing and other varied forms of cooperation that are mutually beneficial to the company and stakeholder groups. This study addresses the specific types of collaboration used in the fashion industry while also examining strategies that have been most successful for fashion companies and perceived benefits of collaboration from the customer perspective. In the present study we define fashion companies and brands as collaborators and their partners or stakeholders as collaboratees. We define collaboration as a cooperative relationship where more than two companies, brands or individuals provide customers with beneficial outcomes utilizing their own competitive advantages on an equal basis. Collaboration strategies entail information sharing and other varied forms of cooperation that are mutually beneficial to the company and stakeholder groups. Through collaboration, fashion companies have pursued both tangible differentiation, such as design and technology applications, and intangible differentiation such as emotional and psychological benefits to customers. As a result, collaboration within the fashion industry has become an important, value creating concept. This qualitative study utilized case studies and in-depth interview methodologies to examine customers' attitudes concerning collaboration in the fashion industry. A total of 173 collaboration cases were identified in Korean and international markets from 1998 through December 2008, focusing on fashion companies. Cases were collected from documented data including websites and industry data bases and top ranked portal search sites such as: Rankey.com; Naver, Daum, and Nate; and representative fashion information websites, Samsungdesignnet and Firstviewkorea. Cases were collected between November 2008 and February 2009. Cases were selected for the analysis where one or more partners were associated with the production of fashion products (excluding textile production), retail fashion products, or designer services. Additional collaboration case information was obtained from news articles, periodicals, internet portal sites and fashion information sites as conducted in prior studies (Jeong and Kim 2008; Park and Park 2004; Yoon 2005). In total, 173 cases were selected for analysis that clearly exhibited the benefits and outcomes of collaboration efforts and strategies between fashion companies and stakeholders. Findings show that the overall results show that for both partners (collaborator and collaboratee) participating in collaboration, that the major benefits are reduction of costs and risks by sharing resource such as design power, image, costs, technology and targets, and creation of synergy. Regarding types of collaboration outcomes, product/design was most important (55%), followed by promotion (21%), price (20%), and place (4%). This result shows that collaboration plays an important role in giving life to products and designs, particularly in the fashion industry which seeks for creative and newness. To be successful in collaboration efforts, results of the depth interviews in this study confirm that fashion companies should have a clear objective on why they are doing the collaboration. After setting the objective, they should select collaboratees that match their brand image and target market, make quality co-products that have definite concepts and differentiating factors, and also pay attention to increasing brand awareness. Based on depth interviews with customers, customer benefits were categorized into six factors: pursuit for individual character; pursuit for brand; pursuit for scarcity; pursuit for fashion; pursuit for economic efficiency; and pursuit for sociality. Customers also placed more importance on image, reputation, and trust of brands regarding the cases shown in the interviews. They also commented that strong branding should come first before other marketing strategies. However, success factors recognized by experts and customers in this study showed different results by subcategories. Thus, target customers and target market should be studied from various dimensions to develop appropriate strategies for successful collaboration.
