The purpose of this study is first to examine the tendency in what kind of activities and difficulties are carried out as family rituals. Second, the study was to investigate the effects of family rituals on family strengths. To accomplish study purpose, 216 married women/men were asked to fill out the survey questionnaires. For analysis of data, SPSS Win program was used to perform Frequency Analysis, MANOVA, Multiple Regression Analysis. (1)In the dinner rituals, it turned out that a main activity was 'serving homemade food' and a majority of subjects had a difficult time establishing a regular ritual due to 'their busy schedule at work'. In the weekend leisure rituals, a main activity was 'paying a visit to suburbs' and a main difficulty was 'lack of mutually available time for all family members'. In the birthday rituals, a main activity was 'preparing a birthday cake' and a main difficulty was 'because family members forget their birthday'. In the wedding anniversary rituals, women's main activity was 'eating out' and men's main activity was 'give a partner to a flower or gift', and a main difficulty was 'because family members forget their birthday' and 'because it was not a wanted celebration'. Finally, in the traditional rituals, women's main difficulty was 'partner doesn't understand my difficulties' and men's main difficulty was 'trouble human relationships with relatives'. (2)The family rituals were significantly different according to the age. (3)'Closeness of family members', 'task performance and problem solving skills' and 'sharing a value system of family members' were affected by the family rituals.

과학교육은 학생들이 장차 과학 기술분야의 직업을 추구하도록 하는 것을 그 중요한 결실의 하나로 잡고 있다. 현재 한국은 과학과 기술의 발전을 교육의 주요목표의 하나로 삼고 있으며, 정부에서는 보다 많은 영재를 과학 기술분야로 유치하려고 여러 가지 정책을 펴고 있다. 그러나 이러한 정책도 결국은 학생이 과학 기술분야로 모여들지 않으면 그 효과가 없게 된다. 그런 점에서 학생들이 어떤 이유로 과학 기술분야를 선택하는지 혹은 기피하는지 그 원인을 아는 것을 중요한 과제라고 할 수 있다. 본 연구는 과학 및 기술분야의 직업을 갖게 되는데 결정적인 역할을 하는 고교생의 문 이과반 선택에 있어 그 진로결정에 영향을 주는 제 요인들을 규명하는데 목적을 두고있다. 연구대상은 대구시내외 남 녀 고교 1학년생 109명(문과 56명, 이과 53명)이었으며 조사방법은 설문지법을 사용하였다. 조사결과는 학생들의 문 이과반 선택에는 장래직업, 대학전공, 적성, 학과목에 대한 능력, 흥미 선호도, 가족 및 주위의 권유 등이 주요요인임을 보여주고 있다. 그중 문과를 지원한 학생들은 대체적으로 자신의 적성 이과과목에 대한 능력부족 인식, 내신 및 학력고사에서의 성적취득용이성 등 주로 자신의 내적 동기와 관련된 요인들을 들고 있는데 비해, 이과를 지원한 학생들은 밝은 직업전망, 가족 및 주위의 권유 등 외적인 동기도 큰 작용을 하고 있음을 보여 대조를 이루고 있다. 또 문과를 지원한 학생은 이과가 공부하기가 어렵고 성적을 올리기도 힘들어 이과를 기피한 경향을 보이는데 반해 이과 지원자는 문과를 기피하여 이과로 왔다는 응답은 별로 없는 점이 대조를 보였다. 본 논문은 이러한 결과가 던져주는 시사점과 과학교육의 개선책에 관한 제언을 제시하면서 결론을 맺고 있다.

국내의 도로용량편람에 근거한 좌회전 신호의 선택기준은 4방향 접근로 각각의 방향별 교통량, 좌회전 전용차로의 유무, 차로수 등의 수많은 요인들을 통해 결정된다. 이 요인들은 각각의 특성에 따라 좌회전 신호의 선택기준에 미치는 영향력이 다르며 그 영향력의 크기에 따라 변수를 결정해야 한다. 그러나 국내에서 사용되고 있는 대부분의 좌회전 신호의 선택기준은 이러한 검토 없이 해당도로의 한 방향 좌회전 교통량과 이와 마주보며 진행하는 직진 교통량, 차로수만을 기준으로 결정되고 있다. 따라서 본 연구는 국내 도로용량편람의 알고리즘을 이용하여 좌회전 신호의 선택기준에 영향을 주는 주요 요인을 밝히고, 이 결과를 이용하여 임계좌회전 교통량 (비 보호좌회전 신호로 신호교차로의 운영효율을 극대화 할 수 있는 최대 좌회전 교통량)을 제시함으로서 비 보호 좌회전 준거를 설정하고자 하였다. 본 연구에 의한 결과는 다음과 같다. 첫째, 좌회전 신호의 선택기준에 영향을 주는 주요요인은 해당도로의 좌회전 교통량, 대향직진 교통량, 차로수, 교차도로의 교통량과 차로수이며, 이 요인들 중에서 해당도로의 차로수가 좌회전 신호의 선택기준에 가장 큰 영향을 미치는 것으로 분석되었다. 그러나, 비 보호좌회전은 일반적으로 2차로에서 운영되므로 보편적인 상황에서의 비 보호좌회전 신호의 선택기준은 해당도로의 좌회전 교통량. 대향직진 교통량 및 교차도로의 교통량에 좌우된다. 둘째, 대향직진 교통량이 커질수록 임계좌회전 교통량은 감소하는 것으로 분석되었다. 셋째. 교차도로의 교통량이 커질수록 임계좌회전 교통량은 감소하는 것으로 분석되었다.

Corporations should make efforts to recognize the importance of projects, identify their failure factors, prevent risks in advance, and raise the success rates, because the corporations need to make quick responses to rapid external changes. There are some previous studies on success and failure factors of projects, however, most of them have limitations in terms of objectivity and quantitative analysis based on data gathering through surveys, statistical sampling and analysis. This study analyzes the failure factors of projects based on data mining to find problems with projects in an audit report, which is an objective project evaluation report. To do this, we identified the texts in the paragraph of suggestions about improvement. We made use of the superior classification algorithms in this study, which were NaiveBayes, SMO and J48. They were evaluated in terms of data of Recall and Precision after performing 10-fold-cross validation. In the identified texts, the failure factors of projects were analyzed so that they could be utilized in project implementation.

The purpose of this study was to explore the determinants of minor and double major satisfaction of university students. To achieve this, F.G.I. was performed with the university teaching assistants to create a questionnaire. The survey was performed to the subject of 239 university students completing minor and double major. A statistical program (SPSS) was used for data analysis and factor analysis, reliability analysis, and multiple regression analysis were conducted. First, it drew three principal factors including need-achievement, class discrimination, and course registration discrimination by conducting factor analysis regarding survey questions on minor and double major. Next, the multiple regression analysis identifying the effects of the three principal factors was conducted. The results indicated three principal factors to be statistically significant. The degree of influence over satisfaction marked the highest in the order of need-achievement, class discrimination, and course registration discrimination. In the conclusion, the positive function and possibilities of minor and double major are proposed.

Researches on the prediction of domestic apartment sales price have been continuously conducted, but it is not easy to accurately predict apartment prices because various characteristics are compounded. Prior to predicting apartment sales price, the analysis of major factors, influencing on sale prices, is of paramount importance to improve the accuracy of sales price. Therefore, this study aims to analyze what are the factors that affect the apartment sales price in Gwangju, which is currently showing a steady increase rate. With 6 years of Gwangju apartment transaction price and various social factor data, several maching learning techniques such as multiple regression analysis, random forest, and deep artificial neural network algorithms are applied to identify major factors in each model. The performances of each model are compared with RMSE (Root Mean Squared Error), MAE (Mean Absolute Error) and R² (coefficient of determination). The experiment shows that several factors such as 'contract year', 'applicable area', 'certificate of deposit', 'mortgage rate', 'leading index', 'producer price index', 'coincident composite index' are analyzed as main factors, affecting the sales price.

Objectives : The objective of the present study was to investigate alexithymia in major depressive disorder(MDD) and subclinical depression(SCD). Methods : Three hundred eighty-six community-dwelling adults(238 females and 148 males, age 19-79; mean age $43.0{\pm}13.9$) were recruited. Structured clinical Interview for DSM-IV(SCID) was conducted for the diagnosis of MDD or other Axis I psychiatric disorders. The Center for Epidemiological Studies for Depression Scale(CES-D) and the Totonto Alexithymia Scale(TAS) were administered to assess depressive symptom and alexithymia, respectively. Among subjects without MDD, those who had minor depressive disorder on the SCID or high scores(i.e. over 16) on the CES-D were defined as subjects with SCD. TAS total score and factor I, II, III scores of TAS in MDD, SCD, and non-depressive controls were compared. Results : Among 386 subjects, 38 subjects(9.8%) were diagnosed as MDD by DSM-IV criteria, while 57 subjects(14.8%) were classified into SCD group. There were significant differences between 3 groups(MDD, SCD and non-depressive controls) in total score($F_{2,383}=14.0$, p<0.01), factor I(difficulty in identifying feeling)($F_{2,383}=23.4$, p<0.01) and factor II(difficulty in describing feeling)($F_{2,383}=7.8$, p<0.01), but not factor III(external oriented thinking)($F_{2,383}=1.8$, p=0.16) of TAS. In post-hoc analysis, both MDD subjects and SCD subjects had higher scores in TAS total, factor I and factor II, compared to non-depressive controls(all p<0.01). In contrast, there were no significant differences between MDD subjects and SCD subjects in any TAS factor. Conclusion : In this study, both MDD subjects and SCD subjects were more alexithymic than non-depressive control subjects. These findings suggest that SCD, as well as MDD, is also related to alexithymia.
