The objective for this research is to analyze the origin of the outbreak of a policy dilemma in the government's pursuance of policy aimed at tackling internet addiction among teenagers, as well as analyzing responsive strategy. Therefore, within this research and as the model of the dilemma being the analytical frame, the aspect of the dilemma has been analyzed through the transformation of contexts, conditions, policy values, alternatives, policy actors and policy decision makers. The major research results are as follows. First, each and every dilemma of 'transformation of context and condition', 'policy value and alternatives', 'policy actors' and 'policy decision makers' in processes of policy in preventing and resolving adolescent internet addiction, it acted as a decisive cause in forming the general dilemma of the policy. Second, the government's strategy in policy response within the policy dilemma conditions turned out to be a duplication of policy, occurrence of contradictions, typical response strategy and cyclical choices. Given these factors, the following characteristics have shown up as a result. First, as the problems in duplication of policy and contradictions occurred within a single policy, the government responded to this dilemma in a typical way, which brought about an even more serious dilemma. Second, the government put in effort to re-regulate two values (protection of adolescents and promotion of the video game industry), which are included in the response policy of adolescent Internet addiction. As a result, the policy dilemma has weakened with respect to the past. However, it has not solved the fundamental problems. This research, taking the results as a background, strives to provide implications for establishing a self-consistent groundwork, which combines policy values and vision for the government to pursue effective responsive policy on adolescent internet addiction, which is becoming more and more severe in the information society in which we live.

The paper studies spark plasma sintering (SPS) of industrially used UO₂-based fuel containing integral fuel burnable absorber (IFBA) of neutrons Gd₂O₃. Densification dynamics of pristine UO₂ powder and the one added with 2 and 8 wt% of Gd₂O₃ under ultrasonication in liquid has been studied under SPS conditions at 1050, 1250, and 1450 ℃. Effect of sintering temperature on phase composition as well as on O/U stoichiometry has been investigated for UO₂ SPS ceramics. Sintering of uranium dioxide added with Gd₂O₃ yields solid solution (U,Gd)O₂, which is isostructural to UO₂. SEM with EDX and metallography were implemented to analyze the microstructure of the obtained UO₂ ceramics and composite UO₂-Gd₂O₃ one, particularly, open porosity, defects, and Gd₂O₃ distribution were studied. Microhardness, compressive strength and density were shown to reduce after addition of Gd₂O₃. Obtained results prove the hypothesis on formation of stable pores in the system of UO₂-Gd₂O₃ due to Kirkendall effect that reduces sintering efficiency. The paper expands fundamental knowledge on pros and cons of fuel fabrication with IFBA using SPS technology.

In this paper, the proposing a fundamental data for a systematic and effective organizational management by examining the extent of the levels of conflict perceiving among individuals of social welfare workers in the Busan community social welfare center, a social welfare organizations, and investigating the related influencing factors are the purpose of the study, The summary of this study is as follows. At first, it is dysfunctional when the level of conflict is either exceedingly high or low in the interrelational conflict aspect. However, the social welfare workers' working in the community social welfare center, the extent of individual conflict is relatively low as 2.37 out of 5 points. Secondly, the multi-regression analysis is operated for controlling the population sociological factors and measuring the effectiveness of the conflict factors to the level of conflict. The influencing factors affects the result in the order of greater extent are communication factor, leader's flexibility of leadership factor, spontaneity among personality, confidentiality. As a result, Not like the case that in the technological bureaucratic organizations such as the enterprises or industrial organizations, in the human service organizations including social welfare organizations, these technological bureaucratic paradigm does not applying directly since the material of organization is composed of humans who are given moral values. Therefore, this paradigm should be put as a presupposition of the conflict management strategy. And, the communication among colleagues, learning a reasonable problem solution method, or the chances of education or training for establishing a sound human relationship should be prepared in order to lower the level of the conflict among individuals in the community social welfare department. Furthermore, professional education programs are needed for not only supporting an effective supervision and consultation(consultation with superiors and colleagues), but also, working with confidentiality and pride as a professional.

There have been increasing interests in the odor generation problems as concerns about the quality of life has been increased recently. Especially, approximately 67% of the odor complaints from environmental facilities are those from sewage treatment facilities and food waste treatment facilities. Moreover, sewage ocean dumping will be prohibited from 2012 by the international and domestic ocean laws, and thus, demand for alternative management plans is increasing. Therefore, it was first selected 5 sewage treatment facilities and 5 food waste treatment facilities where the amounts of waste are relatively immense in Busan, and collect their sludge samples. Then it was investigated the samples' physical and chemical characteristics through proximate analysis, elemental analysis, XRF analysis, and calorific value analysis. Finally, estimate the $H_2S$ emission rates were estimated in order to apply the results as the basic data for providing the fundamental solution for the oder complaints. As a result, the concentration of $H_2S$ in sewage sludge and in food waste treatment facility were 57.3 mg/kg and 19.7 mg/kg in average, respectively. Finally, the units of $H_2S$ in wastes stored in total 10 waste treatment facilities was estimated 16,017,910.0 mg/d.

The purpose of this study is to understand why female labor force participation rates decline in early times after their marriage. Data were derived from the 4th(2001) to 9th(2006) Korea Labor & Income Panel Study. 194 Korean married women in twenties and thirties who had a job before marriage were analyzed. Survival analysis was used to explore the first labor force exit of married women longitudinally. The major findings are as follows. First, nearly half of them went away from labor market in the first 3 years after marriage. Second, child birth was the most significant factor in predicting women's labor force exit. Married women's employment discontinuity tend to be lowered after child birth, with working hour decreasing, and with the number of available family-friendly policies increasing. Married women's income encouraged them to hold on their career, though husband's income and household income were not significant. Third, married women tended to leave their job before giving birth. Women who remained in the labor market at child birth or until a year after birth were inclined to continue their job thereafter. Fourth, maternity leave and childcare leave diminished the probability of employment discontinuity. Many working wives could not use a maternity leave or childcare leave. This study shows married women usually underwent labor market exit in their newly married time. They cannot help facing conflict between the role of mother's and a worker's. Family-friendly policies could encourage working wives to rear child and continue work at the same time. The findings of this study could serve as fundamental material for further studies and would be a key to find effective solution for problematic issues on reconciling work and family.

This study was carried out to investigate the microencapsulatuion of ${\omega}-3$ fatty acid isolated from fish oil and to obtain fundamental information on the utilization of the ${\omega}-3$ fatty acid in the dairy foods field. To obtain the desirable microencapsulation efficiency, 1.5% agar and 0.5% gelatin were used as coating materials, and 0.5% SFAN 60 (HLB 4.5 value) was used to maintain the emulsion stability. The optimal mixing ratio of coating material to core material was 8:2 (w/w). The thermostability of microencapsulated product was not maintained above $60^{\circ}C$. Microencapsulation efficiency was kept at about 90% at $4^{\circ}C$ and $10^{\circ}C$ for 7 days storage at various temperatures. At $20^{\circ}C$ and $30^{\circ}C$, however, about 80% microencapsulatuion efficiency was obtained for 3 days storage. About 80.57% microcapsule was destroyed by 1%> pepsin solution at $37^{\circ}C$ for 10 min.

This study was carried out to obtain fundamental data such as peeling efficiency and quality of potatoes and sweet potatoes peeled by hand, machine and alkali(NaOH). The weight loss by peeling was influenced by peeling methods. Weight losses by rotational brushing-type peeler showed the lowest value, 7.9% in potato, and 7.3% in sweet potato. Any significant differences in moisture content were not found in potatoes and sweet potatoes by peeling methods. The pH of potatoes and sweet potatoes just after peeling were 5.8-6.8 and 6.23-6.63, and decreased somewhat until 3 hrs after peeling. Hardness of potatoes and sweet potatoes peeled by hand with fruit knife were better than that of others. Depending upon the peeling method used the color and color differences undergo some changes in their color and browning. Color difference value of peeled potatoes by hand with a technical tools, and by mechanical peeler such as rotational cutting-type peeler and rotational brushing-type peeler showed just slightly. In particular, changes of rotor differences value of potatoes and sweet potatoes peeled by dipping with 10% NaOH solution at $100^{\circ}C$ was the highest in the samples peeled by NaOH.

Korea Medical Dispute Mediation and Arbitration Agency, "K-MEDI" in abbr. herein-after, is established on Apr. 9, 2012 according to the law cited in the title above for the purpose of settling medical disputes in a prompt, fair and efficient manner. Two special professional organizations are established in K-MEDI, one of them is Medical Dispute Mediation and Arbitration Committee(hereinafter referred to as the "Mediation Committee") and the other Medical Malpractice Appraisal Board(hereinaf-ter referred to as the "Appraisal Board"), the mission of the latter is to investigate the facts concerning the disputed medical conduct and to research as to and apprai-se whether the medical conduct was negligent and whether a causal relationship exists. Each panel organized in the Mediation Committee or the Appraisal Board shall be comprised of five mediators or appraisers, including necessarily a judge or a prose-cutor respectively and any disputed case regardless of the scale, the importance or the complicacy shall be handled by a panel. As the system is not thought efficient or economic, the number of the members comprising a panel or total members com-prising the Mediation Committee or the Appraisal Board shoud be adjusted, and the process shoud be versified, including the "Rapid Process," for instance. A petition for the mediation of a medical dispute shall be rejected if the respondent fails to notify K-MEDI of his/her intention to accede to the mediation within 14days from the day on which the petition for the mediation was served(Art. 27 Cl. 7). As the option of an arbitrary decision whether the mediation proceedings shall be commenced or not given to the respondent by the clause is thought unfair, making the process unstable, and moreover, diminishing the purpose of the system established by the law cited above for solving the medical disputes, the clause shoud be amended not to allow the respondent the option of such an arbitrary deci-sion. K-MEDI shall conduct the "Program for Compensation of Medical Accidents"(Art 46) according to which unavoidable injuries caused by the medical accidents in the cour-se of childbirth and the "Advances for Damages"(Art. 47) that are the compensating moneys paid to victims in medical malpractice cases who fail to receive money at all or partly from the operator or the professional of a public health or medical institution although he/she has a final and conclusive right to be paid by them. Some operators or professionals of such institutions claim that both the programs violate their fundamental rights assured by the constitution, and that it be a justifica-tion of refusal to accede to the mediation. As any of the programs needs not to be conducted by K-MEDI, it may be a proper solution to change the conductor of the programs to avoid the unproductive controversy.

Korea has the highest traffic accident occurrence rate in the world. It means that we are forced to face a tremendous amount of economic loses and great cost of life. Even though this phenomenon consistently has arose as a public issue every year and many researchers have emphasized the importance of safety education as the fundamental solution, we are still trying to make a long-lasting and effective traffic safety education programs for children and adolescents. The purpose of this study was to test the effectiveness of web-based learning for traffic safety in Korea middle school. For this purpose, the instructive model was constructed based on the ASSURE model and a special web-site of education was developed on behalf of practical use of multi-media learning materials for the traffic safety. The research subject was represented by 259 students from second grade in 2 middle schools located in Seoul Korea. The traffic safety education program using web-site was preceded to the 136 students as a case group for 45 minutes total 3 times. Other 126 students are control group those who did not get with this program. The survey was conducted before and after the education. The results of this study were as follow: 1. The knowledge analysis from the comparison between before and after of the lesson showed case group and control group scored average at 11.25 points and 10.97 points. However, after they attended programs, case group scored 13.57 points and control group scored 10.85 points. The difference from the result of the case group was statistically significant(p<0.001). 2. The attitude analysis from the comparison between before and after of the lesson showed case group and control group scored averages at 29.59 points and 28.21 points. However, after they attended program, case group scored 37.23 points and control group scored 32.71 points. The difference from the result of the case group was statistically significant(p<0.05). 3. Regarding the domain analysis by means of web-based traffic safety education, only the case group had a statistically significant score in the case of knowledge 'safe utilization of bicycle' and 'The Characteristic of Automobile and Safer Mode of Walking for Pedestrian'(p<0.01, p< 0.001), and in the case of attitude 'safe walking and crossing' 'The Characteristic of Automobile and Safer Mode of Walking for Pedestrian'(p<0.01, p<0.001). 4. Web based instruction for traffic safety was effective in terms of improving students' knowledge and attitude for traffic safety.
