인간 및 다른 생물들의 DNA 서열이 밝혀짐에 따라 DNA 서열 정보를 이용할 수 있는 계산적 처리방식에 대한 요구가 늘어나고 있다. 본 논문에서는 DNA의 패턴을 분류할 수 있는 면역계 부정 선택에 기반한 알고리즘을 제안한다. 부정 선택은 면역세포 생성시 자신을 인식하지 않는 항원 인식부를 생성하기 위한 과정이다. 이 항원 인식부를 통해 자기와 비자기를 구별한다. 이것을 n개의 자기 또는 비자기 집단으로 확장하고 n개의 항원 집단을 구성하면 n개의 패턴 분류가 가능하다. 본 논문에서는 부정 선택에 기반한 DNA 염기 레벨에서의 패턴 분류방법과 아미노산 레벨에서의 패턴분류 방법을 제안한다.

사람의 지문은 그 인식성능과 종생불변성 및 만인부동성으로 인하여 신원인증을 위한 생채인식에서 가장 많이 이용되고 있다. 최근에는 지문인식의 신뢰성에 더하여, 그 인증속도가 지문인식을 각종 보안 어플리케이션에 응용하는데 있어서 매우 중요한 요소로 부각되고 있다. 본 논문에서는 생체면역계에서의 '자기-비자기' 구별과정에 착안한 빠르고 신뢰성 있는 지문인식 알고리즘을 제안한다. 제안한 매칭알고리즘은 지문영상으로부터 추출된 특징점과 방향성분에 기반하여 만들어지는 자기공간(self-space)에 기반하여 이루어지는 1차 매칭과, 특징점의 기하학적 구조에 의하여 구성되는 로컬구조(local structure)에 의하여 구성되는 로컬구조에 의해 수행되는 2차 매칭의 두 단계로 구성되어 인식의 신뢰성을 유지하면서 인증속도를 향상시켰다.

The purpose of this study is to investigate expertise of mathematic teachers in development of designing assessment items, derived from development of assessing tools, which is a part of assessing competence of mathematic teachers. Analysis was made upon the difference between Pre-service and In-service teachers in terms of self-perception on assessment items. The assessing references of self-perception on developing in designing assessment items consist of followings: one's Beliefs and Self-Rating in designing assessment items. This investigation on self-perception was carried out by both pre-service teachers who are currently enrolled students in college and in-service teachers who are currently incumbent in secondary schools. This analysis based on 310 teachers' answers on self-perception of designing assessment items, both in- and preservice.

The aim of this study is to understand the effects of a self-leadership program on career recognition and self-efficacy in adolescents under probation. As a result, it was discovered that the self-leadership program had statistically significant differences in self-understanding, the understanding of work and the job world, setting a career goal and strategies in the sub-area of career recognition in adolescents under probation while there was no significant difference in the area of attitudes and values of work. The self-leadership program had statistically significant differences in confidence, self-regulated efficacy among the sub-area of self-efficacy of the subjects while there were no significant differences in the difficulty of the challenge. These results suggest that the self-leadership program had significant effects on career recognition and self-efficacy in adolescents under probation. In order to improve the career recognition and self-efficacy in adolescents under probation, further studies on the self-leadership program are needed and care should be paid to its usability.

The purpose of this study was to examine the influence of other-awareness in multicultural adolescents upon psychosocial adjustment and to figure out the mediating effects of self-regulatory ability in this relationship. To achieve this research objective, a questionnaire survey was conducted targeting 127 middle-school adolescents from multicultural families in Busan city. As a result, the other-awareness in multicultural teenagers had a negative(-) influence upon the self-regulation and the psychosocial adjustment. The self-regulatory ability appeared to have a positive(+) impact on psychosocial adjustment. Also, in consequence of verifying the mediating effects of self-regulation in the relationship between other-awareness and psychosocial adjustment in multicultural adolescents, the self-regulatory ability was shown to have a partial mediating effect. In light of this outcome, diverse programs for self-regulation need to be developed in order to enhance psychosocial adjustment in multicultural adolescents. An institutional support from school and community must be made for raising the positive awareness on multicultural families.

생체 면역시스템은 바이러스나 병원균 등의 외부 침입자로부터 자신을 보호한다. 본 논문에서는 이러한 기능을 컴퓨터 면역시스템에 적용하기 위하여 생체 면역시스템의 기본 요소인 T세포를 모델링 하였다. 모델링한 T세포는 MHC 인식부와 항원 인식부를 가지고 있으며, 매칭을 통하여 컴퓨터내의 랜덤 파일로부터 자기 파일과 비자기 파일을 구분할 수 있다. 모델링한 T세포의 유효성을 보이기 위해서 컴퓨터 바이러스의 문제에 적용하여 자기-비자기 구분이 가능함을 보인다.

This study investigated the effects of academic self-efficacy and resilience on perception of professionalism. The survey questionnaire was completed by 313 pre-service early childhood teachers. SPSS Win program was used to perform MANOVA and Multiple Regression Analysis. (1)The self-regulatory efficacy was significantly different according to grade and experience of child care practice. (2)The control and sociality, positivity were significantly different according to grade and experience of child care practice. (3)The perception of professionalism was significantly different according to grade and experience of child care practice. (4)The self-regulatory efficacy and the difficulty preference affected perception of professionalism. (5)The positivity and control affected perception of professionalism. This study indicated that it is necessary to make efforts for increasing perception of professionalism in pre-service early childhood teachers.

This study was attempted to investigate the mediating effect of the tolerance of dating violence in the influence of female college students' perception of dating violence on their sexual self-assertion. The subjects of this study were 161 female students enrolled in universities in the Chungbuk region. As research instrument, Jeong(2013)'s perception of dating violence, Jeong(2016)'s sexual self-assertiveness, and Nam(2003)'s dating violence acceptability were used. For data analysis, frequency, percentage, correlation analysis, hierarchical regression analysis, and Sobel test were performed using SPSS WIN 21.0 program. As a result of the study, first, there was a significant positive correlation between perception of dating violence and violence tolerance(r=.43, p<.001), and a significant negative correlation between violence tolerance and sexual assertiveness(r=-.20, p<.05). Second, the perception of dating violence had a significant positive effect on sexual assertiveness(𝛽=.43, p<.001), and the explanatory power was 19%(F=36.10, p<.001). Third, it was found that the decrease in the effect of female college students' perception of dating violence on sexual assertiveness was significant(Z=2.05, p<.05), violence acceptability showed a mediating effect on the effect of dating violence perception on sexual assertiveness. Based on this study, it is suggested to develop a dating violence prevention program that can lower female college students' acceptability for violence, raise perception of violence, and strengthen sexual assertiveness.

Recently, the localization recognition system research has been studied using various sensors according to increased interest in autonomous navigation flight. In case of indoor environment which cannot support GPS information, we have to look for another way to recognize current position. The Image-based localization recognition system has been interested although there are lots of way to know current pose. In this paper, we explain the localization recognition system based on mark and implementation of autonomous navigation flight. In order to apply to real environment which cannot support marks, localization based on real-time 3D map building is discussed.
