본 연구에서는 SNS 품질요인에 대한 기존 연구에 대해 전문가 집단이 산출한 각 품질요인에 대한 중요도와 사용자 집단이 각 품질요인에 대해 중요하다고 생각하는 중요도의 차이를 알아보고자 하였다. 연구를 위하여 선행연구에서 사용된 SNS 품질요인을 시스템품질, 정보품질, 인터페이스품질, 서비스품질로 구분하여 AHP 기법을 적용하여 전문가 집단과 사용자 집단의 품질요인별 중요도를 실증 분석하였다. 분석결과 전문가 집단과 사용자 집단의 각 품질요인에 대한 중요도의 인식 차이가 나타나는 것으로 나타나 품질평가에 있어 전문가와 사용자의 의견을 종합하는 종합 평가가 필요할 것으로 사료된다.

The purposes of this study are to develop spatial factors for children's libraries and fulfill the evaluation of importance of expert and user groups for it. So, this study developed spatial evaluation factors by analyzing materials of domestic/international groups and associations and precedent studies, drawing spatial factors and organizing them. Next, for the spatial factors developed to 12 evaluation areas and 127 detailed indexes, an importance was evaluated for 4 expert groups; children's librarians, people majoring in early childhood education, elementary school's librarians, people in charge of architecture, etc. and 3 groups; infants, elementary school's lower grades, elementary school's high grades, etc. The evaluation results are as follows. First, the expert groups approved an importance of indexes by evaluating all of the 12 evaluation areas and 120 indexes of 127 detailed indexes as more than 3.0. Second, the user groups also approved an importance of indexes by evaluating all of 12 evaluation areas and 125 detailed indexes of 127 detailed indexes as more than 3.0. Third, as the result of evaluating an importance between expert groups and user groups, there was a difference between two groups in 2 areas among the 12 evaluation areas.

The concept of extraction in orthodontic treatment has been changed many times. Even today, criteria of extraction or nonextraction is still changing. In this study, changes depending on the evaluator's perception of treatment outcomes were compared in both extraction and nonextraction cases. In this study, premolar extracted 59 patients and nonextracted 60 patients, totally 119 patients who finished orthodontic treatment in Dankook University Dental Hospital orthodontic clinic were enrolled. Evaluation sections made up of specialists and laypersons assessed soft tissue traced from lateral cephalometric radiographs with visual analogue scale before and after the treatment. And the results were statistically analyzed. Thus, the conclusions drawn are as follows: 1. Average score is 5.76 in extraction, which is larger than 5.28 of nonextraction case. Improvement of facial profile was more favorably accepted in extraction case. 2. 5.875 in the group of specialists were higher evaluation than 5.165 in the group of layperson. 3. Specialists gave significantly higher ratings in the extraction than nonextraction. 4. A higher rating in extraction case of the layperson group has no significant difference with nonextraction case. 5. Nonextraction patients were given higher ratings from specialist group. 6. A higher rating of specialist group in extraction case has no significant difference with layperson group.

최근 물류환경의 변화로 제품의 신속한 수송과 고객 지향적 물류서비스 제공의 극대화를 꾀하려는 기업들은 제3자 물류의 활용에 커다란 관심을 가지게 되었다. 기업이 제3자 물류업체 활용을 통한 성과를 높이기 위해서는 고객서비스의 향상, 물류관련 비용의 절감 및 물류활동에 대한 운영효율의 향상을 수행할 수 있는 물류업체를 선정하는 것이 중요하다 할 것이다. 본 연구에서는 제3자 물류업체 선정과 관련한 주요 선행연구의 종합적인 고찰을 통하여, 제3자 물류업체 선정에 대한 평가기준들을 도출하였다. 선정을 위한 기준으로 비용, 물류서비스, 업체평가, 정보시스템의 4가지 항목으로 나누었고, 이를 계층화하여 AHP기법을 통하여 분석하였다. 그 결과 상위기준의 상대적 중요도는 물류서비스가 0.425로 가장 높게 나타났고, 비용(0.232), 정보시스템(0.224), 업체평가(0.120) 순으로 나타났다. 비용의 항목에 포함되어 있는 하위기준의 중요도는 경제성이 0.710, 안정성이 0.290으로 나타났다. 물류서비스 항목에 포함되어 있는 하위기준의 중요도는 신뢰성이 0.780, 유연성이 0.220로 나타났다. 업체평가 항목에 포함되어 있는 하위기준의 중요도는 기업역량이 0.507, 관계지향성이 0.493로 나타났다. 정보시스템 항목에 포함되어있는 하위기준의 중요도는 정보인프라가 0.471, 정보활용도는 0.529로 나타났다. 분석에 있어 추가적으로 학계와 실무계 전문가 집단으로 나누어 그 중요도를 산출하였는데, 학계 전문가 집단과 실무계 전문가 집단 모두 상위기준에 있어 물류서비스가 가장 높게 나타났다. 주목할만한 점은 학계 전문가 집단의 경우 정보시스템이 비용보다 더 높게 나타난 반면에, 실무계 전문가 집단은 비용이 정보시스템 보다 더 높게 나타났다는 것이다.

본 논문에서는 안경식 스테레오스코픽 3DTV에 대한 효율적인 주관적 화질평가 방법에 대한 논의를 한다. 3DTV의 주관적 화질평가는 시각피로나 신체적 불편감을 유발하는 요인들을 규명하고 평가하여 사용자가3D 영상물을 관람할 때 이들을 최소화하면서 컨텐츠 제공자가 의도한 입체 깊이를 시청자가 지각 할 수 있도록 도와 줄 수 있도록 가이드라인을 제공하기 위해 이루어진다. 주관적 화질평가를 위해 적절한 깊이감을 갖는 카메라기반의 실영상과 컴퓨터 그래픽 기반의 3D컨텐츠를 사용하였다. 설문은 디스플레이 자체와 3D컨텐츠에 대한 화질평가 구분을 하고, 전문가와 일반인들을 대상으로 이루어졌다. 주관적 평가에 앞서 평가결과에 대한 객관성을 유지하기 위해 Random-dot Stereogram을 이용하여 개인별 입체시 평가를 하였다. 일반인들의 경우 전문가들에 비해 상대적으로 응답편차가 많이 발생하였으나 전문가 집단과 일반인 집단의 설문응답 경향은 대체적으로 일치하였다. 전문가 그룹의 주관적 평가 결과를 적절히 반영하고 일반인들의 응답편차를 줄임으로써 3DTV에 대한 주관적 평가에 대한 시간과 비용을 효율적으로 줄일 수 있을 것으로 기대된다.

The three cities, Yeosu, Suncheon, and Gwangyang, in located in Gwangyang Bay which functions as a representative coastal industrial area in Korea, form a single functional area of living, municipality, and economy. In this regional context, some local merchants and scholars are promoting a inter-municipal cooperation of three cities. This study analyzes how the group of specialists perceives and evaluates the inter-municipal cooperation of three cities. The group of specialists highly evaluate the potential of future development of Gwangyang Bay region, and the relevance and necessity of feasibility of inter-municipal cooperation of three cities. It is estimated that the inter-municipal cooperation of three cities would need 8.3 years for its full-fledged shape. In order to accomplish the inter-municipal cooperation, the sharing the development vision of Gwangyang Bay region and the understanding and consent of the residents for the inter-municipal cooperation are suggested as the most important factors.

Writing is an activity known to enhance higher level thinking. It allows the writer to utilize, apply, and actively expand the acquired knowledge. One way to increase writing activity in classroom setting is to use peer assessment. In this study, we sought to increase the accuracy of peer assessment by having students discuss about the scoring rubric or by referring to an expert's assessment. One hundred and fifty college students participated in the experiment. In the group that referred to the expert's assessment, the accuracy of peer assessment increased when the same piece of writing was evaluated; however, no such increase was observed when another piece of writing was assessed. On the other hand, in the group that discussed about the scoring rubric, the accuracy of peer assessment remained the same when the same piece of writing was evaluated, but increased when another piece of writing was assessed. Also, in the discussion group, the accuracy increased in proportion to the number of comments during the discussion. The results suggest that active and voluntary participation of students increase the accuracy of peer assessment.

The purpose of this study was to draw policy implications for the development and expansion of Korea's forest ODA through investigating the perceptions of stakeholder on the fields that contributed the development of forestry in Korea and would have competitiveness in developing countries and priority fields for Korea's forest ODA. For this, the survey was conducted for 248 subjects from the general and expert stakeholder groups. Chi-square test in cross analysis, independent sample t-test, ANOVA and Duncan test were conducted to compare the difference of perceptions by group. The whole general and expert groups consider that 'forest conservation and rehabilitation' contributed to the development of Korea's forestry most and consider its global competitiveness most high. Comparing expert groups, ODA experts evaluated the competitiveness of 'capacity building for policies, institutions and research' higher than the forestry experts. For priority fields of Korea's forest ODA, general groups perceived 'management of CERs' and 'conservation of biodiversity' most important, showing the clear difference in perception compared to that of experts. In Conclusion, for the effective forest ODA of Korea, the effort to fill the gap between the general and expert groups needs to be made, as well as developing forestry capacity building programs to cope with the fields such as climate change adaptation and biodiversity conservation, which is newly required in a global society, in addition to using the past experience of forest rehabilitation in Korea. It will be useful for the rehabilitation of North Korea's forest in the future.
