The first and the second "Discussion Contest of Scientific Investigation" was evaluated in this study. This contest was a part of 'Korean Youth Science Festival' held in 1993 and 1994. The evaluation was based on the data collected from the middle school students of final teams, their teachers, a large number of middle school students and college students who were audience of the final competition. Questionnaires, interviews, reports of final teams, and video tape of final competition were used to collect data. The study focussed on three research questions. The first was about the preparation and the research process of students of final teams. The second was about the format and the proceeding of the Contest. The third was whether participating the Contest was useful experience for the students and the teachers of the final teams. The first area, the preparation and the research process of students, were investigated in three aspects. One was the level of cooperation, participation, support and the role of teachers. The second was the information search and experiment, and the third was the report writing. The students of the final teams from both years, had positive opinion about the cooperation, students' active involvement, and support from family and school. Students considered their teachers to be a guide or a counsellor, showing their level of active participation. On the other hand, the interview of 1993 participants showed that there were times that teachers took strong leading role. Therefore one can conclude that students took active roles most of the time while the room for improvement still exists. To search the information they need during the period of the preparation, student visited various places such as libraries, bookstores, universities, and research institutes. Their search was not limited to reading the books, although the books were primary source of information. Students also learned how to organize the information they found and considered leaning of organizing skill useful and fun. Variety of experiments was an important part of preparation and students had positive opinion about it. Understanding related theory was considered most difficult and important, while designing and building proper equipments was considered difficult but not important. This reflects the students' school experience where the equipments were all set in advance and students were asked to confirm the theories presented in the previous class hours. About the reports recording the research process, students recognize the importance and the necessity of the report but had difficulty in writing it. Their reports showed tendency to list everything they did without clear connection to the problem to be solved. Most of the reports did not record the references and some of them confused report writing with story telling. Therefore most of them need training in writing the reports. It is also desirable to describe the process of student learning when theory or mathematics that are beyond the level of middle school curriculum were used because it is part of their investigation. The second area of evaluation was about the format and the proceeding of the Contest, the problems given to students, and the process of student discussion. The format of the Contests, which consisted of four parts, presentation, refutation, debate and review, received good evaluation from students because it made students think more and gave more difficult time but was meaningful and helped to remember longer time according to students. On the other hand, students said the time given to each part of the contest was too short. The problems given to students were short and open ended to stimulate students' imagination and to offer various possible routes to the solution. This type of problem was very unfamiliar and gave a lot of difficulty to students. Student had positive opinion about the research process they experienced but did not recognize the fact that such a process was possible because of the oneness of the task. The level of the problems was rated as too difficult by teachers and college students but as appropriate by the middle school students in audience and participating students. This suggests that it is possible for student to convert the problems to be challengeable and intellectually satisfactory appropriate for their level of understanding even when the problems were difficult for middle school students. During the process of student discussion, a few problems were observed. Some problems were related to the technics of the discussion, such as inappropriate behavior for the role he/she was taking, mismatching answers to the questions. Some problems were related to thinking. For example, students thinking was off balanced toward deductive reasoning, and reasoning based on experimental data was weak. The last area of evaluation was the effect of the Contest. It was measured through the change of the attitude toward science and science classes, and willingness to attend the next Contest. According to the result of the questionnaire, no meaningful change in attitude was observed. However, through the interview several students were observed to have significant positive change in attitude while no student with negative change was observed. Most of the students participated in Contest said they would participate again or recommend their friend to participate. Most of the teachers agreed that the Contest should continue and they would recommend their colleagues or students to participate. As described above, the "Discussion Contest of Scientific Investigation", which was developed and tried as a new science contest, had positive response from participating students and teachers, and the audience. Two among the list of results especially demonstrated that the goal of the Contest, "active and cooperative science learning experience", was reached. One is the fact that students recognized the experience of cooperation, discussion, information search, variety of experiments to be fun and valuable. The other is the fact that the students recognized the format of the contest consisting of presentation, refutation, discussion and review, required more thinking and was challenging, but was more meaningful. Despite a few problems such as, unfamiliarity with the technics of discussion, weakness in inductive and/or experiment based reasoning, and difficulty in report writing, The Contest demonstrated the possibility of new science learning environment and science contest by offering the chance to challenge open tasks by utilizing student science knowledge and ability to inquire and to discuss rationally and critically with other students.

본 연구는 야외체험활동에 관한 안전 담론에 대한 미디어 프레이밍의 관련성을 탐색고자 2013 해병대 캠프 사고를 연구대상으로 선정하여 분석하였다. 설정 기간은 해병대 체험캠프가 급격히 증가한 대한민국의 천안함 폭침 사건 일인 2010년 3월 26일부터 해병대 캠프 사고 발생 후 2013년 7월 21일까지 보도된 뉴스보도 데이터에서 제공하는 검색사이트를 통해 수집하였다. 또한, 사건 발생 전 138건, 사건 발생 후 73건, 총 211건의 자료를 귀납적 분석을 하였다. 연구 결과 해병대 캠프 보도는 크게 사건전과 후로 나누어져 긍정적 미화 프레이밍과 부정적 프레이밍으로 구분된다. 구체적으로 사고 발생 전의 프레이밍은 야외체험 활동에 관하여 극기체험을 통하여 인내심과 자립심을 키움으로써 자존감을 높이고 더 나아가 사회구성원으로서 협동심을 고취할 수 있는 최고의 교육프로그램으로 확대하여 해석하는 경향을 보였다. 이어 사고 발생 후에는 늘 그렇듯이 안전 불감증 문제를 공론화시키는 양상을 보였다. 이러한 미디어의 이중적 보도 행태의 프레이밍은 자칫 우리 사회가 요구하는 안전 문화 확산에 걸림돌이 될 것으로 사료 되며, 이에 언론은 보도 시 좀 더 냉철하고, 객관적인 태도가 필요하다.

Objectives : Depression disturbs the individual life from the loss of productivity to suicide. Furthermore the whole society is also influenced by depression in social and economic areas. Many scientific treatment methods are known to be effective in depression. But in reality more than half of patients with depression prefer self help treatment rather than medically based treatment. For the patients with mild depression and primary physicians, it is reasonable to provide the evidence based self care including self help or alternative treatment. This study is supported by the Korean Health 21 R&D Project for the Depression Center to establish the Korean treatment guideline for depression. Methods : The members of Depression Center including the authors attended the workshops where the methods of evidence based medicine such as literature search, quality evaluation of the articles, making the level of evidence were educated. The professional librarians helped the authors for get the searched articles. Among the total of 354 abstracts of systemic review and 300 abstracts of random controlled trials, 3 systemic reviews and 2 random controlled trials were the main structure of evaluation. Result : Among the 37 self care methods known to be effective for depression, 11 kinds of methods were worth of evaluation. The first step for the self care of mild depression is to use St. John's wort, exercise, bibliotherapy, and light therapy in depression during winter season. Acupuncture, negative ion therapy, massage, relaxation technique are known to be efective with evidence. Music therapy, hypnotherapy, and aromatherapy are known to be effective but until now the evidences is insufficient and further evaluations are needed. Conclusion : Among 11 listed self-care methods, several methods need more evidence especially in Korean situation. Exercise is the most recommendable evidence based self care method in Korea nowadays. St. John's wort is effective with evidence, but it is not the OTC drug in Korea, so it is not recommendable now. For the bibliotherapy, there is no book such as "Feeling Good" in Korea. Only the introductory book about depression is available. Publishing the self help book based upon cognitive behavioral approach or psychodynamic approach is needed. Light therapy is practiced in a few clinics, but not self-help style. Exposure to the sunlight is recommended in the level of commen sense. These self care methods are for the mild patient. Moderate to severe patients with depression should seek the professional treatment.

The inner and outer environment surrounding companies becomes more insecure and unpredictable due to sudden changes. Because the change of environment surrounding companies can deeply affect the existence of companies, continuous innovation of organization is required to develope management ability. Also, to conquer insecure present and future of companies effectively, organizations of companies have voluntarily coped with insecurities and intense competitions through endless organization innovation. Externally, globalization, openness, and relaxed regulation intensify competitions; consumers' requests get varied; consciousness of members of organizations have changed. Due to those factors, companies are placed in a situation that they should practice endless inner innovation. Internally, competitive power has weakened due to decline in productivity and inefficiency of indirect parts of company has increased. From those factors, managers increasingly request inner innovation and pursue organization innovation for the purpose of effective usage of extra resources and being prepared for the future. The managers who operate organization innovation think that systematized approach to organization innovation is the most practical, and actually operate the thought. However, the negative side of the thought is not neglectable. To minimize inner and outer resistance and to operate organization innovation successfully, some innovation strategies that properly reflect several issues related to organization innovation should be prepared. Another words, organization innovation should be operated differently by cases that if it focuses on personal perspective or on organization's. For many cases of our country, several techniques of organization innovation have been adopted in a short time and operated without making its original use. Therefore, this study looks into major Issues that should be considered for more successful operation of organization innovation, from both personal aspect and organizational aspect. When considering such aspects and operate organization innovation, there is more possibility to succeed on organization innovation. Now, Korean companies have overcame trial period and reborn as global companies. Take warnings by the ordeal under IMF administration, this is time to secure international competitive power by using developed innovation techniques and transform to superior company. Managers need to recognize that to try successful organization innovation is the shortcut to reborn as competitive company, and should take a continuous and profound search for decisive factors to succeed on organization innovation. To operate successful organization innovation, first, at the step of planning organization. innovation, the company should understand the company's capability, position in market and relationship with competitors. Then, the company should establish a distinguished innovation strategy which is of the whole company's aspect, so that the company can freely choose various technique of organization innovation that suits for the company's capability and needs, and unfold the organization innovation movement. Establishing strategy in the aspect of the total company is very important because it offers clear focus of the purpose of adopt, priority and distribution of resources. Second, at the step of operating organization innovation, the company should define concrete purpose and method to evaluate the results that are expected to obtain by adopting organization innovation in advance. While pushing forward, the company should set proper time of examination(milestone) and inspect if expected results are shown. Third, at the step of afterward management of operating organization innovation, the company requires a thorough afterwards verification if targeted results are obtained and of confirmation of successful or failure factors. Also, the company should cultivate specialists in the company who can accumulate and continuously spread the know-how learned during organization innovation promotion, so the know-how don't remain only in certain departments or to a few people in charge. The company should also give effort to maintain the accumulated innovation techniques to be continued.
