It has been taken for 10 years since Climate Change Convention could it be made. And Kyoto Protocol will come into force as an international law as from 16. Feb 2005. As based on it, Annex I countries will implement their mitigation projects on GHG reductions and press developing countries on GHG reduction target. Korea has not duty target on it yet. But it will be held a COP(Conference of Party) on negotiation for reduction target of second commitment period. If Korea has a real duty, Industry sector should reduce GHG emissions. Then Market mechanism will be need to introduce for this. This study started having a question "Is it possible to introduce emissions trading in Korea?". To solve the problem, this study analysed GHG emissions, marginal abatement cost, market price with 11 companies of industry (about 36% of Korea emissions). minus target is impossible to implement reduction target ver base year (2002). And emissions trading scheme also can't make the market without additional policy and measures. This study suggest that it is need to import credits and give a subsidy of government to encourage it. The imported credit can reduce the demand curve within the marginal abatement cost curves. But the effectiveness of credit is not the same as continually growth. As a result, Allowing 40% credit into emissions trading market is the best to reduce costs. However, a subsidy is the little bit difference. A subsidy make marginal abatement cost curves down for itself. Giving 30% for subsidy, it is the best. Considering both of importing credits and subsidy, it is the best effects in the reducing cost for company. especially 30% is the best effects respectively. This Study show that government wants to consider designing emissions trading, encourage participants competitiveness, and encourage the early action, government has to allow credit trading and give a subsidy to participants.

This study was carried out to determine effects of long-term supply of Cordyceps militaris mycelia on cordycepin content in milk in dairy cows. Ten Holstein cows in the early stages of lactation were divided into two groups. Control group received no supplement whereas treatment group received 6% of C. militaris mycelia of their dry matter intake for 6 months. Feed intake, milk urea nitrogen and somatic cell counts were not affected by long-term supply of C. militaris mycelia for the whole period. In addition, milk yield and milk composition were not affected by long-term supply of C. militaris mycelia at any time of the periods with the exception of milk protein content and yield. The average of milk protein content and yield from the whole period was higher for C. militaris mycelia supplement group than for the control group. As expected, cordycepin in whole blood and milk was not detected in the control group. The range of cordycepin content in the treatment was 0.31~0.38µ/ml and 0.18~0.26(µ/ml for whole blood and milk, respectively. Individual variation was found to be very high and, furthermore cordycepin was undetected in some milk samples. Thus, no clear pattern could be seen in cordycepin content in milk throughout the whole period. Overall, the results of the present study suggest that the transfer efficiency of cordycepin to milk by supplementing C. militaris mycelia in dairy cows was unpredictable and low.

We believe, 'Dokdo is clearly an inherent territory of Korea, in the light of geographical and historical facts', This paper aims to discuss Japanese multidimensional approach on the Issues of Dokdo(Takeshima) in the context of Territory Education. We considered the matter from various angles that supported by the ministry of Foreign affairs and the ministry of Education in national scale, as well as shimane prefecture government and municipality scale. Therefore, It is likely that the approach of territory education on Dokdo in Japan is variable and potential, and is temporary state of condensation, depends on Korea-Japan's political, economical, social, and international conditions. More studies of the new approach must be done for the new implications of Territory Education that embraces all meanings and events according to the disposition of neighbouring condition of Dokdo in world context, keeping out emotional and nationalist sympathies. The result of consideration in this paper are as follows. First, Territory Education in japan was focused on geography, history, Civil, Social Studies, compared with focusing on History in Korea. Second, It is centered on "korea is illegally occupying Dokdo, against which Japan has been consistently making strong protests" rather than simple historical approach. Thirdly, Their approaches seek to be succeeded the identity and importance of Territory Education to next generation rather than the present solving problem.
This study was conducted to find out about the implementation status of dental treatment infection control standards of dental hygienists. The subjects of research were the dental hygienists working at dentist offices in Chungnam, Cheonan-si using self-input method from July 25th, 2012 to August 1st 2012. The collected data was analyzed after computerized statistical processing using SPSS 18.0. For hepatitis B vaccination, the results were high with 75.0% of answers being 'yes' or auto-active immunity, but for the latest hepatitis vaccination period showed highest results in '5 years or more ago' with 48.0%. Although 93.0% answered that vaccination was important, the percentage of replies that they had vaccination education was relatively low with 41.0%. For the use of personal protection tools the use of protective goggles was low compared to the use of masks and medical gloves. The percentage of subjects that answered that they always wash their hands before treatment was relatively low with 56.0% compared to 82.0% of subjects that answered that they always washed their hands after treatment. Dental treatment equipment washing before sterilization, use of packing and re-sterilization of tools with damaged packing showed high results for 'yes', but the ratio of subjects that answered 'no' to water line management was low with 39%.
This study examined the impacts of tariff reductions on timber products in the new round of WTO negotiations on domestic timber products markets and presented the measures to minimize their impacts. Scenarios on reductions in tariffs were developed based on result of UR negotiation and prospective issues on scope of tariffs bound, base rates for negotiation, degree of tariff cuts, etc. emerged during preparatory meetings held to launch the New Round of WTO Negotiation. Korea Timber Market Model(KORTIMM) developed by Korea Forest Research Institute was used to simulate the impacts on forest products markets by scenario. It was estimated that their impacts on net imports would be much larger than those on both consumption and production. The results showed that their impacts on plywood market and on net imports of processed forest products would be much larger relatively but that their impacts on log market and on consumption and production of processed forest products would be less than 1 percent. It was estimated that log consumption would be reduced due to reduction in domestic production of processed products and thus both production and imports of logs would be reduced as well. In oder to minimize the impacts, efforts should be made to start negotiations to reduce tariffs with bound rates for bounded products and with applied rates for non-bounded products, to expand the implementation period and to maintain the status of developing country. In addition, it might be one of countermeasures to use legitimate measures consistent with WTO rules such as anti-dumping, countervailing measures and safeguards.
This study intends to analyze outcomes in labor market of students who graduated from provincial colleges. And For this aim, this study used 'Youth Panel Data' (2001, 2002) of HRD Korea Work Information Center. The reference groups are students who graduated from capital region colleges. The main results of this study are as follows. Students who graduated from provincial colleges have difficulty in acquiring job information than capital region college graduates. And students who graduated from provincial colleges get first job in smaller firm than capital region college graduates. The monthly wage level of students who graduated from provincial colleges is less than that of capital region college graduates. And the outcomes in labor market of students who graduated from Chungcheong region colleges are better than those of students who graduated from Yeongnam region and Honam region colleges. As results of this study show, there are differences between provincial college graduates and capital region college graduates. And there are differences between Chungcheong region college graduates and another region (namely, Yeongnam region and Honam region) college graduates.
Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants, found in the many environments. PCBs exerts various toxicological effects, including endocrine-disrupting activity. Most researches with these toxicants performed with soil matrix with mixtures of congeners, namely Aroclor, while the biological activities have been tested with animals. However, studies with pure congeners are limited. In this study, 5 congeners were synthesized and their fates (bioaccumulation, degradation, kinetics) were studied in carrot-soil system. The soil half-lives of biphenyl, PCB-1, PCB-3, PCB-77, and PCB-126 were 20.2, 16.0, 11.6, 46.5, 198.0 days, respectively. In general, the longer half-lives were observed with the higher hydrophoicity of PCBs. Times, required for maxium accumulation of PCBs in carrot (Tmax) were 10-20 days for most congeners and the concentrations were 0.4-2.6 mg/kg. The concentrations of PCBs in carrot were kept as constant after Tmax, except PCB-126. The concentration ratio between carrot and soil after 90 days of treatment were 1.7, 8.1, 1.9, 1.8, and 5.9 for biphenyl, PCB-1, PCB-3, PCB-77, and PCB-126. Because of the increase of biomass, the total residual amount of PCBs in carrots however, increased till the end of experiment. The portions of PCB-126 in carrot were 1.1% of the soil residues at 90 days after planting.

Purpose : This study was conducted to survey the preliminary data on risk behaviors and to identify the factors that prevent risk-behaviors in late adolescence. Methods : Freshmen(n=1,297) beginning the first semester in Korea University, Seoul, Korea completed self-administered risk behavior questionnaires, comprising 5 domains : demographics, smoking, drinking, drug abuse and sexual behavior. Results : The rate of smoking experience was higher in people having friends who smoke and the predictors of transition to current smoking were male gender, urban residence, friends' smoking, and nicotine dependence. The rate of high risk drinking was higher among students who are male and who had experience of heavy episodic drinking. The study group showed a low prevalence of narcotic users, but two-thirds of students could get medicine easily without prescriptions. The prevalence of sexual experience was 6.5 percent, and the sexual education was not a predictor of contraceptive behavior. The prevalence of homosexuality was 1.6 percent, and the rate of mostly heterosexuality was higher in female students. Conclusion : The main targets of youth health education should be campaigns aimed at atcessation of reinforcing risk behaviors and the development of a surveillance system for the prevention of chronic disease. These results can be used to find risk factors of health-risk behaviors among late adolescents.

The purpose of this study was to examine the relations between fatigue, family function and self-esteem among middle-aged women in menopausal periods. Data were collected through self-administered questionnaire survey form 133 middle-aged women. The data collection was done from March 2nd to April 10th, 2012. As a results, there were significant differences in fatigue by education level and menstrual status. And, there were significant differences in family function according to education level and marital status. Also, there were significant differences in self-esteem by education level, marital status and monthly income. Fatigue was negatively related to family function and self-esteem. And family function was positively related to self-esteem. These results suggest that nursing intervention should be developed to strengthen family function and self-esteem as a way to regulate fatigue for middle-aged women in menopausal periods. Especially, it is necessary to pay more attention to health management of middle-aged women belonging to menopausal transition, with low-income, low-education level.
The United Nations Climate Change Conference, Durban 2011, ended on December 12, 2011, 36 hours over its schedule, delivering the Durban Package, which consisted of, inter alia, the extension of the period for Kyoto Protocol term and the launch of Ad-hoc working Group on the Durban Platform for Enhanced Action. Despite the positive progress made in Durban, the future of post-2012 climate regime still seems cloudy. Before the Durban conference, some of Annex I countries with emissions reduction commitment under the Kyoto Protocol's first commitment period openly declared their intention not to participate in the second one, reducing the effectiveness of Durban agreement. Parties to the conference have a long list of difficult issues disturbing the materialization of the new legal agreement in 2020 such as level of mitigation targets of individual countries and legal nature of their commitment. Given this uncertainty, the Korean government should reinforce its domestic climate policies rather than settling in the fact that it remains as a non-Annex I county party under the Durban Agreement due to the extension of the Kyoto Protocol period. Domestically, it needs to continue to raise the public awareness for rigorous climate policies to transit its economy to low carbon pathway which reduces the country's dependency on fossil fuel in the long term. It is also important to implement cost effective climate policies to cope with domestic resistance and international competitiveness. Internationally, its priority would be working for trust-building in the on-going negotiation meetings to encourage meaningful participation of all parties.
