Training, unlike education in holistic perspective, not only affects individual's potential of work competencies such as knowledge and technology, but also affects the job performance in organizational perspective. The effectiveness of training for civil servants who participated in mock jury trial learning of Suwon-si was verified using CIPP model. Participants valued the significance of the process of training rather than the conclusion that draws a certain solution, and based on the comparison and analysis of pre·post evaluations, the educational effect of mock trial training and its utilization at work in the future was higher than before the training, proving its effectiveness. In terms of the implications of training programs in addition to the program planner's evaluation, participant constitution in consideration of sex or employment period is needed for learning interaction among various learners, and information acquisition training on various local issues and conflict situations, as well as the combination of deliberation learning, are needed. in addition, it may be supplemented through customized conflict management raining related to pending projects for the effectiveness of training.

Purpose The online comments on news content have become social information and are understood based on deliberative democracy. Although the related research has focused on the relationship between online comments and their deliberative quality, the social information provided by online comments consists of not only direct information such as comments themselves but also indirect information such as 'likes' and 'dislikes'. Therefore, the research on online comments and deliberative quality should study this direct and indirect information together, and the direction and the degree of the indirect information should be also considered with them. Design/methodology/approach This study distinguishes comments by the attached 'likes' and 'dislikes', identifies highly supported and highly unsupported comments by the intensity of 'likes' and 'dislikes', and investigates the relationship between their existence and the deliberative quality measured as the topic diversity. Then, we applied topic modeling to the 2,390 news articles and their 74,385 comments collected from five news sites. Findings The topic diversities of the supported and unsupported comments are related to the topic diversity of all comments but the degree of the relationship is higher in the case of supported comments. Furthermore, the existence of highly supported and unsupported comments is led to less diversity of all comments compared to the case where those comments are absent. Particularly, when only highly supported comments are present, topic diversity was lower than in the opposite case.

This experiment has been conducted to find out a effective decomposition method of popped rice hulls which are hard to be decomposed in vitro. It was found that the C/N ratio of 35 was better than the C/N ratio of 20 for improving the decomposition ratio of popped rice hulls. The addition of rice bran accelerated the decomposition of popped rice hulls. The real decomposition rate of popped rice hulls for 10 days was merely 8 percent. This poor decomposition ratio seemed to be come from the chemical constituent of rice hull which has 20 percent of silica content. It was considered that the addition of rice bran speeded up only the decomposition of bran itself by increasing the number of microorganisms. It was also observed that color changes developed from the decomposition of rice hulls proved not to be a yardstick for the degree of decomposition.

The Broadcasting Law amended in January 2007 declared to adopt universal right to view(known more widely as Universal Access Right, UAR), the right to access broadcasting programs on such major sports or other events that are likely to catch the gaze of the public television viewers. Then its implementation rule was issued in February 2008, and under the regulations the Committee of Ensuring Universal Access Right has been established, where detailed action measures and guidelines are currently in the process of preparing. However, it is no question that an effectiveness of the implementation system of Universal Access Right presupposes sufficient amount of discussion and social consensus. At present, the major focus in this issue is on the matters including which type of events is subject to UAR and what criteria are desirable in determining which broadcasting company has priority. In this context, this study aims at identifying implications for policy by examining the precedent cases of Europe, Australia, and other countries, where UAR is enacted and implemented. Further, this study tries to draw up a specific scheme for ensuring universal right to view through conducting a survey on public television viewers. We will include specific guidelines for selecting events of public attention, criteria for selecting broadcasting companies regarding priority, and relevant operating rules regarding relayed broadcasting.

The goal of this paper was to understand the skill-up experiences of ex-participants of the customized training program in Technical High Schools for Small and Medium Business during first 2 years in Company through qualitative interviews with 3 purposefully selected ex-participants. Their core skill-up experience in this period was assumed as the shift from' dependent worker' to 'independent worker' on the base of literature review. The results of this study were following : 1. The small and medium companies offered a few formal training for newcomers, production-site orientation through short job rotation, linking them with skilled workers and job manuals or job standards. 2. Authentic skill-up experiences were combined with a structured reprimand, peer learning, deep learning through reflection on one's own experiences. 3. There were a few handicap conditions that disturbed their skill-up activities: the skilled worker don't open their skill toward new corner; the ex-participants in company had no time to learn anything meaningful to up-grade their competency.

Broadcast-seeded rice in submerged paddy frequently lodge in the field. In general, the causes of lodging in rice cultivation differ with different cultural methods. This study was conducted to investigate the causes of lodging in broadcast-seeded rice (BSR) and hand-transplanted rice (HTR) under four nitrogen (N) levels. Lodging in BSR was mainly a root lodging due to shallow root distribution, while that in HTR showed a bending type owing to deep rooting system. At the upper soil layer (0-5cm from the surface of ground) the root distribution of BSR (65.2%) was much larger than that of HTR (51.6%), whereas at the 5-10cm soil layer the root distribution of BSR (18.5%) was much smaller than that of HTR (28.0%). The depth of buried culm base was much shallower in BSR (1.2cm) than in HTR (4.0cm). The plant height, fresh weight, lodging index, culm diameter and thickness in HTR were much greater than those in BSR, and the breaking strength of lower internode was similar in the two cultivation methods indicating that HTR would have more lodging causes than BSR. In spite of . the more advantages to lodging resistance in BSR it severely lodged in the field. The main lodging-inducing factors of BSR were the shallow root distribution and shallow depth of buried culm base. Besides these, the higher ratio of gravity center of culm was an important factor. This result suggested that for the fundamental prevention of lodging in BSR, an ideotype of rice plant with ' a deep-rooted behavior ' should be developed.

Variations of temperature and physicochemical environment during composting of a mixtures(2:1, v/v) of cattle manure and rice hulls(CMR) in two different composting methods, static windrow(SW) and aerated static pile system(ASPS), were monitored for evaluating the efficient composting system in greenhouse. The pH of composting materials increased to around 8.9 initially, then decreased and stabilized slowly to the neutral value. Composting materials in ASPS showed a rapid stabilization in pH value from the 4th week comparing to the speed in SW. Thermophilic stage for ASPS Lasted at 3 week whereas 6 weeks for WS. Required time to get thermophilic zone in compost was shorter in ASPS than in WS. Reduction rate in total carbon(T-C) was higher in ASPS than in WS. Organic matter was reduced more rapidly in ASPS than in SW showing 9 percent difference after the 6th week. Total nitrogen(T-N) increased while composting process, showing 9 percent after 6th week in WS and 1.8 percent after 7th week in ASPS. C/N ratio was stabilized after 6th week showing 17 and 21 level in WS and ASPS each. Quantity of ash and mineral content increased during composting in both system, showing higher content in ASPS. Composting process by intermittent, aerated static pile system in greenhouse had a significant effect on the reduction of required period for composting.

Under the pressure of the selection of topics and the presentation rules of mass media, politics in media society increasingly resort to professionalized forms of theatrical staging as a means of self-portrayal. Although these staging methods are not contradictory to what is actually going on in politics, they strongly advantage the tendency to focus exclusively on the staging of an event. Through their competition for public attention, politicians have been developing sophistication regarding placement and staging of events as well as regarding factual information. In the process of this transformation, politics that are issue-related and based on binding decisions are being gradually transformed into symbolic politics. Moreover, through their appearance on TV, politicians first of all need to possess presentational skills which are not necessarily related to their political achievements. Still, presentational skills decide over the success in politics of those politicians. The reason is that a politician who possesses presentational skills is still being perceived as being successful even if his political achievements notedly lag behind. On the other hand, political achievements are being underrated if a politician lacks the talent to present himself in front of the media. “The staging of politics, “politainment”, on the stage of mass media is evolving into a key structure which is responsible for a new coinage of politics in all different kinds of dimensions: the selection of staff, the role of action programs and their impact for the legitimation of political acting, even in relation to therole of pivotal political institutions such as parties and parliaments in the political process. The TV debates during the Bundestag elections of the year 2002 and 2005 are being analyzed and judged as “staging of politics”(politainment). Self-dramatization in media society concerning media discourses about politics and political self-portrayal has become a basic principle of political communication. Self-dramatization is a vital challenge for adequate political communication and content-based orientation in our present media democracies.

This study was carried out to improve the fruit color through ABA treatment and to determine the optimum harvest time for producing high quality fruits in 'Hongisul' grapes. Spraying of $1000 mg{\cdot}L^{-1}$ exogenous ABA at early verasion (70 days after full bloom, DAFB) brought increase of endogenous ABA and soluble solid contents and enhanced fruit coloration. So, it was possible to harvest ABA treated fruits from 85 days after full bloom (15 days after treatment) by accelerated anthocyanin content which increased continuously until 110 DAFB. An increase of soluble solid and decrease of total acidity appeared steadily with the onset of berry ripening. After 100 DAFB, soluble solid content and total acidity did not change significantly, but the berry firmness was suddenly decreased. Consequently, it was suggested that ABA treated fruits need to be harvested at about 100 DAFB because of their short period of marketing by over ripening. On the contrary, harvesting of untreated fruit was totally impossible at 85 DAFB because of their poor berry coloration. But it was possible to harvest them at 100 DAFB based on the soluble solid/acidity ratio, whereas the berry coloration was progressed poorly. On the other hand, the fruits harvested at 110 DAFB showed acceptable berry coloration but their berry firmness was dropped significantly coincide with overripening. Therefore, it was needed to develop an altered production system for improving coloration at around 100 DAFB in 'Hongisul' grapes.

Previous researches on the improvement of logical thinking in Informatics subject have used general logical thinking test and only limited improvement of logical thinking by programming learning result. In this study, the operational definition of the logical thinking in problem-solving process on Informatics education is different from the general logical thinking and the logical thinking of the other subjects. Firstly, we suggested the operational definition of components of logical thinking using the open questionnaire by expert and research team discussion. Also, we suggested the relationship between the operational definition and contents of the 'problem-solving methods and procedure' section in secondary Informatics subject. Finally, this study developed the evaluation contents based on the operational definition of components of logical thinking. The components of logical thinking which was required in problem-solving process on Informatics subject were ordering reasoning, propositional logic, controlling variables, combinatorial logic, proportional reasoning. We suggested the relationship between operational definition and problem-solving process and assessment of logical thinking in problem-solving process on Informatics subject. This paper will give meaningful insight to supply the guideline of the teaching strategy and evaluation methods for improving the logical thinking in Informatics education.
