Decision class analysis (DCA) is viewed as a classification problem where a set of input data (situation-specific knowledge) and output data(a topological leveled influence diagram (ID)) is given. Situation-specific knowledge is usually given from a decision maker (DM) with the help of domain expert(s). But it is not easy for the DM to know the situation-specific knowledge of decision problem exactly. This paper presents a methodology for sensitivity analysis of DCA under incomplete information. The purpose of sensitivity analysis in DCA is to identify the effects of incomplete situation-specific frames whose uncertainty affects the importance of each variable in the resulting model. For such a purpose, our suggested methodology consists of two procedures: generative procedure and adaptive procedure. An interactive procedure is also suggested based the sensitivity analysis to build a well-formed ID. These procedures are formally explained and illustrated with a raw material purchasing problem.

The present study was performed to identify morphologic sub-groupings in Korean children with Class I malocclusions, and to find out anatomic differences between the sub-groups. Standardized lateral cephalometric radiographs of 152 Korean children, aged between 6 and 12 years, with Class I malocclusions were analyzed by the Counterpart Analysis. A statistical method, Ward's Minimum Variance Cluster Analysis, was employed to divide the sample into sub-groups those with similar morphologic characteristics. The results were as follows; 1. There appeared two facial types, Type I and Type II, in Korean children with Class I malocclusions, 48.7% and 51.3%, respectively. 2. In both sub-groups, there existed strong Class III skeletal patterns due to a counterclockwise rotation of the Middle Cranial Fossa alignment, and strong Class II skeletal patterns due to the long Posterior Maxillary vertical dimension and a clockwise rotation of the Ramus alignment. 3. There were no significant differences in Upper Anterior Facial Height between Type I and Type II, $52.6{\pm}2.92mm\;and\;52.8{\pm}3.23mm$, respectively. 4. The Lower Anterior Facial Height in Type II was longer ($66.0{\pm}4.03mm$) due to the long Posterior Maxillary vertical dimension, the clockwise rotation of the Ramus alignment, and a clockwise rotation of the Mandibular plane alignment than that of Type I ($64.2{\pm}4.15mm$).

This study is to investigate the effect of the amusement factor and the motive of participation in skin-scuba class on the satisfaction with university life with the university students participating in the skin-scuba class and to provide the practical research data for the development of the marine sports, for the proper operation of skin-scuba class, and for the leisure life which the university students may lack. For these purposes, technical statistics between questions were disposed in order to grasp the average and standard deviation on each variables, exploratory factor analysis and reliability analysis were conducted for the reliability and validity of the scale, and correlation analysis and multiple regression analysis were conducted to test the casuality of amusement factor, the motive of participation in skin-scuba class and the satisfaction with university life as the research methods. Research results showed that it was confirmed that the amusement factor and the motive of participation in skin-scuba class act as the important variables in the satisfaction with university life and it was predicted that the motive of participation in skin-scuba class and the amusement factor had interrelation with parameter. Therefore, a variety of programs reflecting the amusement factors should motivate the university students to particiapte in the skin-scuba class to increase the satisfaction with university life and to encourage the re-participation of students.

정보저장소에 저장된 클래스 부품들은 검색, 추출과정을 통한 부품의 다양한 시각적 정보가 부족하고 정확한 정보의 표현 기능이 요구되고 있다. 따라서 본 연구는 클래스 부품을 정보저장소에 저장하기 위해 객체의 구문분석 방법과 추출 Viewer 기능을 연구하였다. 분석과정에서는 클래스명, 멤버함수, 속성 등을 추출하고 클래스 자체정보와 클래스 사이의 상속관계, View를 위한 다이어그램 정보 등을 추출하였다. 또한 추출한 분석정보를 시각적으로 표현할 수 있는 추출 Viewer 기능을 구현하여 클래스 부품의 재사용과 생성, 삽입, 삭제 기능을 보였다. Viewer 기능은 객체의 상속관계와 클래스에 대한 구성정보를 보여주며, 단순한 부품의 재사용에 그치지 않고 클래스를 생성할 수 있는 기능을 추가하여 클래스 부품의 효율적 관리와 재사용성을 높이도록 하였다. 따라서 본 연구는 클래스 부품 정보, 상속관계, 계층도의 정보와 프로세스 등으로 분류하였고 추출 Viewer 기능을 통한 객체의 이해력을 높이고, 객체 생성을 위한 프로토타입을 지원한다.

본 연구에서는 초등학교에서 시행되는 온라인 수업 운영 방법 중 '콘텐츠 활용 및 과제수행 수업 운영 방법'과 '실시간 쌍방향 수업 운영 방법'에 대한 수업만족도를 비교 분석하였다. 연구자는 '콘텐츠 활용 및 과제수행 수업 운영 방법'과 '실시간 쌍방향 수업 운영 방법'의 수업만족도를 비교·분석하기 위해 실험연구를 진행하였으며, 연구 집단은 경기도 화성시의 D 초등학생 98명을 선정하였다. 학생들을 대상으로 '콘텐츠 활용 및 과제수행 수업' 과 '실시간 쌍방향 수업'을 각각 진행하였으며, 각각의 수업 운영 방법에 따른 학생들의 수업만족도를 분석하였다. 분석결과 '실시간 쌍방향 수업 운영 방법'에 대한 수업만족도가 높게 나왔으며, 학생의 특성에 따른 만족도를 분석한 결과 과제수행을 잘 못 하는 학생과 수업에 집중을 잘하지 못하는 학생의 경우 '콘텐츠 활용 및 과제수행 수업 운영 방법'의 만족도가 더 높게 나왔다. 이를 통해 '콘텐츠 활용 및 과제수행 수업 운영 방법'과 '실시간 쌍방향 수업 운영 방법' 간의 장단점이 있으며, 학생의 실태를 명확히 조사하여 수업을 진행함으로써 맞춤형 온라인 수업이 될 수 있도록 제언한다.

Purpose: In this study, we aim to provide primary source of data for developing a learning program that enhances the students' learning by critically analyzing and adopting the effective class participation factors of the students. Methods: A questionnaire survey has been conducted from the beginning of May to the end of October, 2017. Subjects of the survey was the dental technology students living in W-city et al by random sampling method along with written informed consent. Out of 630 distributed questionnaires, 584 results were used for our analysis. Results: Firstly, the average score of the class participation of all the subjects was 3.08 points out of 5.0, which was broken down into class activity (3.53 points), passion about class (3.51 points), communication factors (2.88 points), class preparation (2.77 points), class extension (2.76 points). Secondly, statistically significant correlations were found between class participation and class satisfaction as shown in (p<.01). Class participation factors that affect the class satisfaction were class preparation(p<.001), class activities(p<.001), passion about class(p<.001), which reveals positive and meaningful results. Explanatory power of the model turned out 50.3%. Conclusion : Considering that class preparation, class activities, and passion about class played a key role in class satisfaction of the student, teachers need to be open minded to reflect the learners' personalized demands and needs in preparing and managing their class. Additionally should be in tandem that provides the students with various routes of class participation.

Purpose: To examine the results of PBL classes for sophomore nursing students during one semester. Method: Self-reflection journals and class evaluation questionnaires were collected from 121 nursing students and analyzed. Results of class evaluation questionnaires were analyzed using mean scores, SD, frequencies and percentages. Significant statements were derived by repeated review of the self-reflection journals by the researchers. Results: The statements, 'Understanding of PBL' 'Improvement of human relationships' 'Expansion of nursing knowledge' 'Excellency in nursing class and application of nursing skills in nursing practices' and 'Improvement of learning ability and attitude during classes' were derived from the self-reflection journals. Analysis of class evaluation questionnaires showed the following scores: prerequisite of PBL (3.0/4), role of facilitator (3.48/4) and satisfaction with PBL learning (3.31/4). Also some complaints such as lack of adequate references in the library, and confusion in at the beginning of PBL were noted. Conclusion: PBL was effective. Using the results of the study for planning a more effective PBL class syllabus is recommended.

본 연구에서는 사회복지시설 종사사의 직무만족도 유형을 살펴보고 유형별 예측변인과의 영향관계를 검증하였다. 이러한 연구목적을 검증하기 위해 보건복지부의 '사회복지시설 실태조사'(2014년) 데이터에서 직무만족도 변인에 모두 응답한 11,660명을 최종 분석하였다. 잠재프로파일 분석결과, 사회복지사의 직무만족도 유형은 4집단으로 나타나 '최상 직무만족도집단', '중상 직무만족도집단', '중간 직무만족도집단', '최하 직무만족도집단'으로 명명하였다. 다항로지스틱 분석결과, CLASS4(최상 직무만족도집단)를 준거집단으로 하여 CLASS1(최하 직무만족도집단)과 비교해 노동강도대비 보수수준 평가, 타직종대비 보수수준 평가, 시설안전도, 인권보장도를 높게 인식할수록 CLASS4(최상 직무만족도집단)에 속할 확률이 높아지는 것으로 나타났다. 다만, 이직의사는 낮을수록 CLASS4(최상 직무만족도집단)에 속할 확률이 높아지는 것으로 나타났다. CLASS4를 준거집단으로 하여 CLASS2집단, CLASS3집단도 비교분석 하였다.
