This study aims to analyze the effects of tooth-brushing facilities (TBF) at middle schools that installed TBF in 2012 as part of the oral health project in Seongdong-gu, Seoul. The subjects were the first graders at A middle school that installed TBF previously and B middle school that installed TBF in 2012. The results are as follows: DMFT, DMFS and CPI didn't show significant difference by schools (p>0.05), but code (0) was higher and code (2) was lower in female students than male students (p<0.05). As to PHP index, the students at A school with TBF indicated better oral hygiene (p<0.01). In the research on before and after installing TBF, the oral hygiene was improved significantly more after the installation than before (p <0.01). In the comparison on the oral health-related behavior, the percentage of not brushing after lunch was higher B school than A school and the frequency of toothbrushing after lunch was higher A school than B school (p<0.01). About the reasons why not to brush after lunch, there was difference in 'lack of the place' as A school showed 2.6% while B school without TBF indicated 14.2% (p<0.01). About the changes of the oral health-related behavior before and after TBF installation, the percentage of not brushing after lunch increased from 78.7% to 83.8% after the installation. The average frequency of tooth-brushing after lunch for one week also decreased from 0.50 to 0.34 (p>0.05). Among the reasons why not to brush after lunch, 'lack of the place' significantly reduced, but 'because other friends don't do it' increased greatly after the installation (p <0.05). Only with the improvement of oral health knowledge, we cannot expect either clinical or behavioral significance. Not only schools but policies of governmental agencies and financial support, cooperation of community-related groups for program development and evaluation will contribute altogether to helping teenagers to habitualize proper oral health management.

Consumer organizations usually lead the opinions of the consumers. This study was performed to investigate the perceptions and information needs of consumer organizations on food additives for the promotion of risk communication. A survey was conducted for 4 weeks in March 2012 by using a self-administered questionnaire consisting of 32 questions. Total 111 responses were collected for analysis. 'Safety (91.0%)' was the most important factor influencing the purchase of processed food, and both 'food additives (24.3%)' and 'environmental pollution (23.4%)' were considered as main risk factors. The longer the career of the members had, the higher negative perceptions on food additives (p<0.01). About 70% of the respondents who had known KFDA's researches on evaluating safety of food additives answered that researches were not enough to make sure the safety. Although lectures and other domestic organization were the main channels for getting information, 'TV' was considered as the most suitable way for it. 'Poor risk communication (32.4%)' was pointed out as the serious problem of government's food safety policy. Based on these results, consumer organizations' low level of trust on government should be overcome by continuous supply of information what they need to facilitate risk communication on food additives.

The adolescent period, during which physical, spiritual, and physiological growth and development occurs, is important for the development of healthy dietary habits. Particularly, eating a regular breakfast improves eating habits and school life in adolescents but few studies have investigated the effects of eating breakfast on these outcomes. Therefore, this research was performed to investigate the effects of eating a regular breakfast provided by the 'Breakfast Club Program' on eating behaviors and school life. A total of 315 high school students were recruited for the program from 10 high schools in nine districts among 25 districts in Seoul during August to December of 2013. The average age was $17.8{\pm}0.8$ years and 38.1% of students were females. Based on 315 subjects, 38.3%, 35.7%, and 17.1% increased their intakes of breakfast (P=0.001), fruit (P=0.033), and milk (P<0.001) up to 5~7 times per week, respectively. The intake frequency of fruit (P<0.001) and eating breakfast (P<0.001) increased noticeably after program participation. Based on 64 students performing dietary record, intakes of cereals (P<0.001), mushrooms (P=0.027), and fruits (P=0.002) increased while intakes of eggs (P=0.001) and fat and oils (P=0.019) decreased after the program. Consumption of energy (P=0.004), plant protein (P=0.012), carbohydrates (P<0.001), dietary fiber (P=0.026), iron from plant sources (P=0.009), potassium (P=0.043), zinc (P=0.013), vitamin $B_1$ (P=0.043), and vitamin C (P<0.001) increased whereas intake of cholesterol (P=0.002) decreased. Regarding school life, the score for 'comfortable and cheerful starting of a day' (P=0.001) and 'healthy starting of a day' (P<0.001) increased significantly. This study indicates that a regular 'Breakfast Club Program' may establish healthy eating habits and school life in teenagers.

This research was conducted to investigate the consciousness of demander on National Forest Management System and to seek for solution to activate it by measuring the variables such as the extent of goal achievement on the system, the extent of importance on function of national forest, benefit for participation of the system, and the extent of importance on the system as well as the extent of demander recognition and intention of participation on the system like, Cooperative Forest Program and People's Forest Program. The target of this investigation is to categorize consumers of National Forest Management System (NFMS) into four types such as environmental organization that do not participate in the system, environmental organization that participate in the team, company to publish a white paper on environmental and local government. As a result, the intention of participation was showed in C Type (62.7%), among fields that respondents interested in participation were tree planting and forest tending (56.2%). However, the rest of the participants were reluctant participate in the NFMS due to more benefit (72.2%) of corporate social responsibility from other fields than those from the field utilizing forestry. If only, diverse facilities related to national forest and active supporting policy are provided by Korea Forest Service, social participation using forest resources would be considered. Although 61% among A Type recognized NFMS in advance, the prime reason for not utilizing are the problems with reserving place for participates in and the inconvenience to participate in on-site. Type D shows slightly high interest in People's Forest Program (3.69). Also, it shows high interest in Forest Recreation (4.15) and Forest Reports (3.90). Particularly, it indicates that GyeongGi-Do and GangWon-Do local government prefers Forest Experience, and Cheolla, ChungCheong and GyeongSang local government prefer Forest Reports. Based on the above study, we finally suggest that legal alignment of the system, and the provision of incentive for inducement of voluntary participation by Corporate Social Responsibility (CSR), and establishment of new exclusive nongovernmental organization be able to operate the system as the solution to activate NFMS in terms of the consumer.

While in the early stages of space activities only a few states engaged in the use of outer space, as is well known, commercial space activities have grown dramatically in recent years. Both states, state institutions, and international governmental organizations as well as many private enterprises are engaged in such commercial use of outer space by now. This development is not reflected in the present state of space law. The existing international instruments of space law were developed and finalized before this development and thus only provide very few and sometimes unfitting provisions for the commercial use of outer space and particularly the use by private enterprises. Law formulated in an era when the word "privatization" had not even been coined cannot contain potential problems caused by the increasing commercialization of outer space. For the promotion and further development of such commercial use of outer space it is necessary to clarify and establish the legal framework for such use, because participants will need this information for their future investments in this field. The purpose of this paper is to research and make an analysis of the contents and international regulation of international space commerce, which is rapidly proliferating and to review the process of improvement on national legislations relating to the commercialization of outer space in a few main space advanced countries to make the sustainable progress of commercial space activities project in international society. The legal implications of matters such as international commercial launch services, the liability aspects of such services, intellectual property rights, insurance, product liability insurance and materials processing could one day will be subject to regulated by international space law as well as domestic law. In fact, the question of commercialization is linked to the question of sharing benefits of space activities, and this currently is an agenda item in the Legal Subcommittee of UN COPUOS. Most of developed countries have enacted the national legislation for commercial space activities relating to the development of our space as follows : The National Aeronautic and Space Act of 1958 and the Commercial Space Act of 1998 in the United States, Outer Space Act of 1986 in England, Establishment Act of National Space Center of 1961 in France, Canadian Space Agency Act of 1990 in Canada, Space Basic Act of 2008 in Japan, and Law on Space Activity of 1993 in Russia. Becides there are currently three national legislations relating to space development and commercial space activities in Korea as follows : Aerospace Industry Development Promotion Act of 1987, Outer Space Development Promotion Act of 2005, Outer Space Damage Compensation Act of 2008. Commercial space great promise for the utilization and expansion of human outer space activities but aspring commercial actors must recognize that foreign policy, as well as obligations to the international community as a whole, ensure that commercial space activities will not operate in a legal and regulatory vacuum. As commercial space matures the law and accompanying regulation will most certainly evolve and choose to become participants in the inevitable evolution of law and regulation.

This study, as a case where the environmental conflict and dispute arose between the use and the conservation as in the other protected areas in Korea, took the first step to build ecological citizenship to solve various and complicated issues in a fundamental level by providing a basic information on differentiated environmental perceptions of the locality and the visitors of Seoraksan National Park. The questionnaire survey was employed on September 6th and 7th with 150 residents of the park area and 200 visitors of Osaek-Daechungbong trail. Total number of 13 survey questions was introduced using Dunlap and Liere's NEP index. The result shows that the perception of 'balance of nature' was more dominant to the perception of 'humans over nature' and the perception to the 'limits to growth' was also somewhat positive in both groups. The differences in environmental perceptions between the groups exist; the visitor group tended to have more positive level of acceptance of NEP views. Such differences in perceptions suggest that a different normative approach should be taken to the residents of the national park with less pro-environment in their perceptions when policy making. It thus seemed possible that ecological citizenship could be realized since the younger and the higher education level are, the more pro-environment. The findings of the research may cause some concerns however, because the study has been confined as a case study with basic understanding of environmental perceptions and its differences between the interest groups. More extensive research is required to confirm if this is generalized.

The purpose of this study was to examine the satisfaction level of parents with elementary school students in some metropolitan areas with the pit and fissure sealing program in a bid to raise awareness of the importance of the preventive treatment and accelerate the spread of it. The subjects in this study were 231 parents who had school children and resided in Seoul and Gyeonggi Province. After a self-administered survey was conducted in October and November 2008, the collected data were analyzed. The findings of the study were as follows; 1. As to places for receiving the preventive treatment, 111 respondents (48.1%) experienced pit and fissure sealing in dental clinics, and 88 respondents(38.1%) did that in dental hospitals. 177 people(76.6%) received that treatment from dentists, and 16 respondents(11.3%) did that from dental hygienists. 2. Concerning whether to be for or against the pit and fissure sealing program, more than half that numbered 143(61.9%) supported that program, and 88 respondents(38.1%) didn't. As for satisfaction level, they expressed the biggest satisfaction with the preventive effect of that treatment($3.92{\pm}.85$), and were least satisfied with the cost($1.91{\pm}.86$). 3. Regarding links between general characteristics and satisfaction level, they were statistically significantly different in satisfaction level with the cost according to residential area and the number of child, and age made a statistically significant difference to their satisfaction level with the preventive effect of it. 4. As for relationship between warranty term and whether to be for the pit and fissure sealing program or not, 45(31.5%) out of those who supported the program were provided with no warranty, and 32(36.4%) out of those who took a stand against it were provided with no warranty, either. Warranty was provided to 12(8.4%) respondents of the former group without a fixed term, but that's not the case for any of the latter. The warranty term made statistically significant differences to their agreement or disagreement to the program(p<0.05).

Although several studies have reported that Cr, Cu and As can leach from CCA-treated woods, few studies have been conducted on this topic in Korea. Therefore, this study was conducted to monitor Cr, Cu and As leaching from CCA-treated wood products and to develop a rapid identification method for CCA-treated wood products by using indicators such as PAN stain. Soil samples were collected at depths of 0-70 cm and wood samples were collected by thickness of wood layer. The soil and wood samples were then digested and analyzed for Cr, Cu and As concentrations using an atomic absorption spectrometer. The As and Cu concentrations decreased sharply with depth from 34.38 and 33.65 mg $kg^{-1}$ at 0-1 cm to 1.72 and 7.84 mg $kg^{-1}$ at 70 cm, respectively. In general, As was more mobile than Cr and Cu in the soil. For wood samples, the Cr, Cu and As concentrations were higher in the outer layer (0-0.5cm) than the inner layers (0.6-4.5cm). Evaluation of rapid identification methods revealed that 100% acetone with 0.1% PAN indicator was the best combination for detection of CCA-treated wood in the field.

Background: The prevalence of pulmonary tuberculosis has decreased progressively after the control of the tuberculosis began as national control. But as diabetes, malignancy, immunodeficiency disease recently tend to be increased, the tuberculosis become to the important national health problem. So, this study was designed to observe the state and the change of the prevalence and the clinical status of pulmonary tuberculosis for recent 10 years at one women's university. Method: We retrospectively investigated the epidemiology and the clinical status of 612 patients who were registered at the Ewha Womans University Health Center by analyzing records from 1983 to 1992. Results: 1) The prevalence rate had been steadily decreased from 0.63% in 1983 to 0.11 % in 1992. The prevalence of freshman and the incidence rate according to the entrance year while in the university significantly decreased since 1989. 2) In classifying by registered source, 45.6% of students were detected by annual periodical health examination, 34.5% by entrance physical examination, 12.0% by hospital, 5.4% by health center clinic, 2.5% by reentrance physical examination, sequentially. 3) The students with past history of tuberculosis were 70(11.4%) and 61(10%) suffered from pulmonary tuberculosis. The patients with family history of tuberculosis were 142(23.3%). 4) There were 530(86.6%) with minimal disease, 79(12.9%) with moderate and only 3(0.5%) with far advanced, when classified by the severity of disease. 5) The initial symptoms were mild breathing difficulty in 30.1%, sweating in 14.9%, fatigue in 14.3%, febrile sense in 11.7%, hemoptysis in 8.2%, sequentially. 6) The duration of treatment was $10.6{\pm}3.6$ months in mild group, $14.9{\pm}5.2$ months in the moderate group(P<0.05). 7) The side reactions of the drug were GI trouble in 7.2%, hepatitis in 1.8%, skin rash in 0.8% and streptomycin side in used patients in 9.1%. Conclusion: The prevalence of pulmonary tuberculosis among the students in one women's university was significantly lower than that of university students and 20-24 year-old age group announced in tuberculosis survey on a national scale, and significantly decreased since 1989. The treatment effect was desirable in student's group managed by university health center.

Local opposition and protest constitute single greatest hurdle to the siting of locally unwanted land uses(LULUs), especially siting of high-level radioactive disposal not only throughout Korea but also throughout the industrialized world. It can be attributed mainly to the NIMBYism, equity problem, and lack of participation. These problems are arisen from rational planning process which emphasizes instrumental rationality. But planning is a value-laden political activity, in which substantive rationality is central. To achieve this goals, we need a sound planning process for siting LULUs, which should improve the ability of citizens to influence the decisions that affects them. By a sound planning process, we mean one that is open to citizen input and contains accurate and complete information. In other word, the public is also part of the goal setting process and, as the information and analyses developed by the planners are evaluated by the public, strategies for solutions can be developed through consensus-building. This method is called as a co-operative siting process, and must be structured in order to arrive at publicly acceptable decisions. The followings are decided by consensus-building method. 1. Negotiation will be held? 2. What is the benefits and risks of negotiation? 3. What are solutions when collisions between national interests and local ones come into? 4. What are the agendas? 5. What is the community' role in site selection? 6. Are there incentives to negotiation. 7. Who are the parties to the negotiation? 8. Who will represent the community? 9. What groundwork of negotiation is set up? 10. How do we assure that the community access to information and expert? 11. What happens if negotiation is failed? 12. Is it necessary to trust each other in negotiations? 13. Is a mediator needed in negotiations?
