  • 인터넷 접속서비스에 대해서는 사전적 규제를 하지 않는 것이 세계적인 추세였으나, 최근 유럽에서는 인터넷 접속서비스에 대해서 사전적 규제를 가할 수 있는 지침이 채택되었다. EU가 2003년 7월에 채택한 「2003년 프레임워크」는 종래의 수직 통합형 산업구조가 인터넷 기술발전에 따라 물리적인 네트워크, 전송서비스, 콘텐츠로 정보통신산업이 층별로 세분화되어 가고 있다는 사실을 반영한 새로운 규제체계로 평가할 수 있다. 이 규제체계의 방향성은 경쟁이 미진한 분야에는 사전적 규제, 경쟁이 활성화된 분야에는 사후적 규제를 가하는 것이다. 본 고의 목적은 일본의 인터넷 접속서비스에 관한 시장 및 규제 동향을 소개하는 것이다. 여기에서는 먼저 일본의 인터넷 접속서비스 사업자의 현황을 개관한 후, 인터넷 접속서비스에 대한 정부차원에서의 규제동향을 고찰한다. 일본에서는 인터넷 접속서비스에 대하여 사전적 규제를 하지 않고 있다는 점을 감안하여 일본의 대표적 ISP 사업자라 할 수 있는 JPIX와 NTT 동서를 대상으로 인터넷 접속서비스의 사업현황과 이들 기업에 접속하기 위한 접속조건 등을 살펴본다. 맺음말에서는 현재 일본에서 이루어지고 있는 인터넷 접속서비스에 대한 규제동향을 우리나라와의 비교 관점에서 고찰하고 우리나라에의 시사점을 제시하고자 한다.

  • The purpose of this study was to analyze 'how STEAM activities affect students' science process skills and science-related attitudes'. For more accurate, we have set 31 sixth-grade students from Gyeong-gi Province as an experiment group, and another 31 as a comparative group. We developed a STEAM program based on the educational concepts: Creative Design and Emotional Touch. Through pre-post experiment design, we have introduced TSPS, and Test of Affective Aspects. For TSPS, the comparative group scored higher average grade before the process. After the process, however, the experiment group exceeded the other. The result was considerable enough to verify that the science process skills were bolstered through the STEAM program(p<.05), Similar result was derived regarding the science related attitude. Students in the comparative group originally showed higher degree of interest to science. When the STEAM program was carried out, the standing reversed. The increase in the number of science related attitude indicates the program valid(p<.001). Furthermore, when we asked the students who participated in the experiment how they recognized the STEAM activity, we received positive answers: they consider the program efficient and well suited to the class environment. Conclusively, the STEAM program was proven to be effective for improving science process skills and attitude, and was perceived affirmative.

  • The converted accident rates that included in Pre-Qualification (PQ) are to evaluate the results of accidents which have occurred. Therefore, it is demanded the development of proactive evaluation contents to evaluate the safety management activities and efforts on construction companies. The purpose of this study is to provide basic data for the establishment of proactive evaluation contents at public construction project in Korea through the collected and analyzed the PQ documentation applied by public agencies in Los Angeles, USA. The results indicated that diverse reactive safety evaluations are implemented to examine accidents which occurred in past projects such as occupational health insurance, regulation violation. And also, when the accidents occurred, it is evaluated the proactive safety management actions such as safety education, accident prevention programs, and safety management plans are reflected on the evaluation. Thus, if proactive safety related evaluation contents are established and reflected in PQ examinations together with diverse existing reactive safety evaluations considering converted accident rates, not only the existing function of converted accident rates can be reinforced but also businesses' active safety management activities can be induced and decreases in the construction industry's accident rate can be expected.

  • This study was conducted to develop a group counseling program to solve the problem of maladjustment of military personnel and to verify the effectiveness of the program. The 12 session CBT and ACT program for military soldiers experiencing emotional and behavioral problems was developed and the effectiveness was verified by conducting a program once a week for soldiers in the army units based in South Chungcheong Province. Adult Self Report scale(ASR) was implemented for pre-post test and analysis, and descriptive statistical analysis, cross-analysis, paired sample t-test, and independent sample t-test were performed to analyze the results. The results indicated are as follows: First, the preliminary homogeneity test between groups showed that the two groups had homogeneous demographic characteristics and the characteristics of the variables. Second, as a result of the pre-post test verification, both CBT and ACT groups showed significant changes in problem behavior totals, internalizations, and externalizations. Third, there was no difference between the pre-post-examination of the CBT group and the ACT group. This study is meaningful in that it was involved in the maladjustment problem within the military unit, and compared the effectiveness between the two theories, and proposed the study of control groups and further studies on more diverse and diverse subjects that were not implemented under the circumstances of the unit.
