본 연구에서는 다양한 density profile 특징추출에 기반한 염색체 자동분류방법들의 성능을 비교분석하였다. density profile은 염색체의 밴드패턴을 가장 잘 표현한 특징으로 염색체의 중심축을 구성하는 화소들의 밝기 값을 추출하는 방법이다. 염색체의 밴드패턴은 염색체의 끝단까지를 잘 표현해주어야만 정확한 염색체번호를 확인할 수 있다. 따라서 염색체의 중심축을 추출하여 염색체 끝단까지 확장 처리한 방법에 대한 성능을 확인하였다. 염색체 중심축에 위치한 화소만을 이용한 프로파일은 잡음에 민감할 수 있으므로 이를 해결하기 위하여 염색체의 중심축에 대한 화소 값 대신 주변 밝기 값들에 대한 평균을 이용한 국소평균방법과 중심축의 수직라인 상에 존재하는 화소 값들에 대한 평균을 구한 수직평균방법을 비교하였다. 분류알고리즘은 k-NN을 사용하였고, 실험데이터는 (주)Gendix 로부터 제공받은 임상적으로 정상인 100명(남자 50명, 여자 50명)으로부터 추출한 4600개의 염색체 영상을 훈련데이터와 테스트데이터로 각각 50%씩 랜덤하게 분리하여 실험하였다. 실험결과 중심축을 확장하고 수직평균에 대한 프로파일을 특징으로 추출하여 분류한 경우가 가장 좋은 성능을 보였다.

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.

Public Signs guiding drivers on the road should help make decisions within a short period of time, so appropriate information should be effectively expressed at the point. Currently, the road marking rules revised by the law show a significant change in the type of information, expression method, and weight of expression compared to existing road signs to be based on road name addresses. This study analyzed whether the revised road signs changed based on the road name were effective in perspective of perception-cognition-understanding-projection and examined whether they provided appropriate information for the actual driving environment. Based on the analyzed information, an experiment was conducted to present an improved design, evaluate the degree of visibility compared to existing road name-oriented signs, and a qualitative investigation was conducted on the suitability of the sign contents. Through this, it is expected that more suitable driving information and measures to increase intuitive visibility can be reviewed.

This paper studied the effects of risk cognition of personal information and self-expression information on conation of privacy protection. In the first study, 88 college students who volunteered for this research were surveyed about risk cognition of personal information and conation to protect it. In the second study, after an information-seeking expert collected and organized the self-expression information that 88 volunteers had expressed on SNS, and then showed the organized self-expression information to 88 volunteers, and then 88 volunteers were surveyed about risk cognition of self-expression information and conation to protect it. As results of the first data analysis, the risk cognition of personal information had the greatest influence on non-disclosure of personal information, followed by reduction of the disclosure scope and law institutionalization requirement. As results of the second data analysis, SNS users openly expressed their opinion or life-style, but when they realized that self-expression information can be accumulated and become sensitive information, they had conation to protect their self-expression information such as non-disclosure, reduction of disclosure scope, and law institutionalization requirement. The implication of this study is that we have overcome the limitations of existing researches that can not explain information protection behavior on SNS.

Objectives : This study aimed to examine a correlation between the somatic complaints, emotion, vocabulary and alexithymia as a component of personality in normal persons. Methods : 204 subjects were collected by age-based systematic sampling from the 662 persons without confirmed medical illness. We used the Korean version of 20-item Toronto Alexithymia Scale(TAS-20K) to measure alexithymia. The somatic complaints were checked by the list of somatic symptoms on the diagnostic criteria of somatization disorder and major depressive episode in DSM-IV. The vocabulary was evaluated by the total number of associating-words from the spontaneous association of word and the secondary association to given words. The anxiety and depression were evaluated using 5-point self-report scale. Results : 1) The degree of alexithymia was significantly correlated with the somatic complaints, anxiety, depression. 2) The somatic complaints were significantly correlated with the anxiety and depression. 3) The number of associating-words showed negative correlation with the age. 4) The degree of alexithymia was not correlated with the number of associating-words. Conclusion : The more degree of alexithymia increased, the more somatic complaints appeared. There was a significant correlation between the degree of alexithymia, anxiety and depression. But the degree of alexithymia was not correlated with the amount of vocabulary.

This study examined the effect of valence for best reply on the conformity of general reply in online environment. A total of 194 participants participated in this study, each participant assigned randomly in three experimental groups(positive, negative, and control). Participants were asked to read online news article, best reply and general 6 replies, and then, to write their own opinions in the reply section. In addition, the level of self-expression and issue commitment were measured. The contents of reply participants written was categorized three valence(positive, negative, and neutral) by the four experimenters' judgment. The mean of inter-rater reliability was 84.9%. The results indicated that the level of self-expression and issue commitment were comparable across experimental conditions. However, the result of cross-table analysis showed that there is a significant difference in the valence of general reply across experimental conditions. Specifically, there were significant difference in the valence of general reply between positive and negative experimental group and positive and control group, but there is no significant difference between negative and control group.

study identified secondary school chemistry major teachers' perceptions of sublimation related to the drying phenomenon of frozen wash and representation of the phenomenon on phase diagram. The subjects were 53 teachers for the questionnaire developed for this study, and interviews. The two professors who majored physical chemistry and one professor who majored analytical chemistry at teacher's college were interviewed for teacher educators' perceptions of sublimation. The results showed that forty one teachers among fifty three teachers thought that the drying phenomenon was sublimation. The most teachers who thought that the phenomenon was sublimation responded as a reason that solid state changes to gas state. The teachers who thought that the phenomenon was not sublimation responded as a reason that the 1 atm of air pressure was not the condition of sublimation. Seventeen teachers thought that the drying phenomenon of frozen wash could be represented on phase diagram, but thirty four teachers thought that it could not. But most teachers confused the scientific representation of the phenomenon, and felt difficulties to teach the contents to students.

The purpose of the research was to verify the mediating effect of social support and cognitive emotional regulation strategy when office worker's emotional expressive ambivalence influences on interpersonal stress. A survey was conducted with 422 office workers from August to September of 2018. SPSS, AMOS and Mplus were used for descriptive statistics, correlation analysis, verification of structural equation modeling and mediated effect. There was a partial mediating effect in emotional expressive ambivalence of self-defense model, a complete mediating effect in relational emotional expressive ambivalence model. In both self-defense and relational emotional expressive ambivalence model, double mediation effect of passing through support and cognitive emotional regulation strategy in the relationship between emotional expressive ambivalence and interpersonal stress was significant. This study sought ways to reduce interpersonal stress by increasing the level of perception of social support and using adaptive cognitive emotional control strategies for office workers.
