Background: Absorbable plates are widely used in open reduction and internal fixation surgeries for facial bone fractures. Absorbable plates are made of polyglycolic acid (PGA), polylactic acid (PLA), polydioxane (PDS), or various combinations of these polymers. The degradation patterns of absorbable plates made from different polymers and clinical courses of patients treated with such plates have not been fully identified. This study aimed to confirm the clinical courses of facial bone fracture patients using absorbable plates and compare the degradation patterns of the plates. Methods: A retrospective chart review was conducted for 47 cases in 46 patients who underwent open reduction and internal fixation surgery using absorbable plates to repair facial bone fractures. All surgeries used either PLA/PGA composite-based or poly-L-lactic acid (PLLA)/hydroxyapatite (HA) composite-based absorbable plates and screws. Clinical courses were confirmed and comparisons were conducted based on direct observation. Results: There were no naturally occurring foreign body reactions. Post-traumatic inflammatory responses occurred in eight patients (nine cases), in which six recovered naturally with conservative treatment. The absorbable plates were removed from two patients. PLA/PGA compositebased absorbable plates degraded into fragments with non-uniform, sharp surfaces whereas PLLA/HA composite-based absorbable plates degraded into a soft powder. Conclusion: PLA/PGA composite-based and PLLA/HA composite-based absorbable plates showed no naturally occurring foreign body reactions and showed different degradation patterns. The absorbable plate used for facial bone fracture surgery needs to be selected in consideration of its degradation patterns.

본 연구의 목적은 수요자 관점의 커피 전문점 종사원을 위한 교육 프로그램은 어떤 교과목을 이수해야 하는지 알아보고자 현재 커피 관련 교과목을 개설한 대학의 외식경영, 외식 서비스, 커피 교과목에 대한 중요도와 수행도를 분석하는데 있다. 분석방법은 빈도분석과 T-test, IPA 분석을 실시하였다. 연구 결과는 첫째, 커피 관련 교과목에 대한 중요도와 수행도는 전체적으로 커피 전문점 종사원들이 인식하는 교육 교과목은 중요도 보다 수행도가 낮게 나타났다. 그 중에서 원가관리와 커피학 이론에서 큰 차이가 있는 것으로 나타났다. 둘째, 교육 교과목의 중요도와 수행도의 IPA 분석에서는 I사분면은 약점 항목으로 원가 관리, 외식마케팅, 커피학 이론 과목이 해당이 된다. II 사분면은 유지 항목으로 외식 서비스, 커피 추출 실습, 에스프레소, 카페라테와 카푸치노, 라떼아트 과목이 해당된다. III사분면은 필요성이 결여되는 과목들로 외식경영, 외식 프렌차이즈, 서비스 실무 영어, 커피 로스팅 과목이 해당된다. IV사분면은 중요도는 낮으나 수행도가 높은 과목들로 산업체 현장 실습 과목이 해당된다. 연구의 한계점으로는 선행 연구의 부족으로 인하여 커피 전문점 종사원의 특징적인 요소를 반영하지 못하였으며, 설문지역을 수도권으로 한정하였기 때문에 표본이 전체 커피 전문점을 대표했다고 할 수가 없다고 생각된다.

Scenario-based learning (SBL) has been used in a variety of training situations across different disciplines. Despite its seemly widespread use in construction management discipline, very few attempts have been made to explore its effectiveness and the respective students' learning experience. Using a survey research design, this study aims to investigate students' perceptions on SBL approach in construction management courses. The specific objectives are: (i) to identify the characteristics of a favourable SBL environment, and (ii) to explore the students' learning experience and effectiveness of the SBL approach. The results show that the four characteristics of a favourable SBL environment are: effective team formulation, constant engagement with lecturer, working in a group, and incorporation of motivational incentive for participation. The students really appreciated the opportunities to apply concepts learnt in the lectures in their SBL group work. Also, they perceived that the SBL approach is effective in developing their reflective and critical thinking skills, analytic and problem-solving skills and their ability to work as a team. These findings should facilitate more critical approaches to similar form of teaching methods.

More than 70 percent of terrestrial territory of Korea is mountainous areas where degradation becomes serious year by year due to illegal tombs, expanding golf courses and stone mine development. We elaborate the potential usage of high resolution image for the monitoring of the phenomena. We made the classification of tombs and the statistical radiometric characteristics of graves were identified from this project. The graves could be classified to 4 groups from the field survey. As compared with grouping data after clustering and discriminant analysis, the two results coincided with each other. Object-oriented classification algorithm for feature extraction was theoretically researched in this project. And we did a pilot project, which was performed with mixed methods. That is, the conventional methods such as unsupervised and supervised classification were mixed up with the new method for feature extraction, object-oriented classification method. This methodology showed about $60\%$ classification accuracy for extracting tombs from satellite imagery. The extraction of tombs' geographical coordinates and graves themselves from satellite image was performed in this project. The stone mines and golf courses are extracted by NDVI and GVI. The accuracy of classification was around 89 percent. The location accuracy showed extraction of tombs from one-meter resolution image is cheaper and quicker way than GPS method. Finally we interviewed local government officers and made analyses on the current situation of mountainous area management and potential usage of KOMPSAT-II images. Based on the requirement analysis, we developed software, which is to management and monitoring system for mountainous area for local government.

Objectives : This study investigated the effects of teaching English medical journals to traditional Korean medical students as a way of integrated curriculum, focusing on evidence-based traditional Korean medicine (EBKM) in the light of globalization of traditional Korean Medicine. Methods : 232 students (l16 1st year and t 16 2nd year) were asked to complete a questionnaire at the end of the course in order to validate the course's efficacy on acquisition and utilization of the latest medical knowledge as well as change of attitude toward English itself. Results : The courses were very useful in reducing discomfort toward English journals and to applying the latest medical knowledge to academic reports, clinical practices, and finally to establish abilities for EBKM. The 1st year students who took the courses for two semesters consecutively showed more significant satisfaction than the 2nd year students with only one semester. Conclusion : The findings suggest that English medical journals are an essential curriculum f3r the advance of EBKM and globalization of traditional Korean Medicine and therefore developing adequate textbooks, teaching methods, and quality of instructors should be considered for successful achievements.
