According as many people use a computer newly, damage of computer virus and hacking is rapidly increasing by the crucial users A computer virus is one of program in computer and has abilities of self reproduction ad destruction like a virus of biology. And hacking is to rob a person's data in a intruded computer and to delete data in a person s computer from the outside. To block hacking that is intrusion of a person s computer and the computer virus that destroys data, a study for intrusion-detection of system and virus detection using a biological immune system is in progress. In this paper, we make a model of positive selection and negative selection of self-recognition process that is ability of T-cytotoxic cell that plays an important part in biological immune system. So we embody a self-nonself distinction algorithm in computer, which is an important part when we detect an infected data by computer virus and a modified data by intrusion from the outside. The composed self-recognition process distinguishes self-file from the changed files. To prove the efficacy of self-recognition algorithm, we use simulation by a cell change and a string change of self file.

The study was done to investigate the mediating effects of communication ability on the relationship among self-awareness, empathy, emotional intelligence and interpersonal competence of nursing students. Data on subject's self-awareness, empathy, emotional intelligence and interpersonal competence were collected using a structured self-reporting questionnaire. During September and December 2019, data were collected from 282 nursing students in J and K cities. Data were analyzed using three-step mediated regression analysis with the SPSS WIN 21.0 programs. Self-awareness, empathy, emotional intelligence and communication ability were positively correlated with interpersonal competence of nursing students. Also, communication ability had a partial mediating effect on the relationship among self-awareness, empathy, emotion intelligence and interpersonal competence. These finding indicate that it will be more effective to education strategies that can increase self-awareness, empathy, emotional intelligence and communication ability together when developing education programs that improve interpersonal competence.

This study examines perceived homophily by the degree of self disclosure among SNS users. In this research, there were three different groups in terms of the degree of self disclosure among SNS users such as strong, medium and weak self disclosure groups The major results are as follows: Firstly, the higher the degree of self disclosure, the more social network service use. In addition, the higher the degree of self disclosure, the smaller the degree of online activity including blog and mini web page. Secondly, the higher the degree of self disclosure, the higher the degree of socio-demographic homophily. It can be argued that the strong group had much more mean scores than that of medium and weak groups in terms of regions, gender, age and vocation except nationality. Also, the higher the degree of self disclosure, the higher the degree of shared homophily except of political opinion homophily.

모바일 로봇이 자기 역할을 수행하기 위해서는 자기위치인식 기술이 반드시 필요하다. 이에 본 논문에서는 기존 초음파 센서만을 이용한 위치인식 기술의 난제와 카메라 즉, 영상처리만을 이용한 위치 인식 기술의 난제를 두 가지 기술의 융합으로 쉽게 해결할 수 있도록 한다.

This study examined the relationship between covert narcissism on depression for College students as a mediator Emotional Clarity and Ambivalence over Emotional Expressiveness through structural equation modeling. To this end, we conducted a survey of 343 university students living in central area of Korea, a measure of CNS, BDI, TMMS, AEQ-K. The result of the study were as follows. First, all the variables had meaningful positive of negative correlations. Secondly, When Covert Narcissism affects Depression, Emotional Clarity and Ambivalence over emotional expressiveness were full mediated. Third, the indirect effects of Emotional Clarity, Ambivalence over Emotional Expressiveness on the effects of covert narcissism on depression were relevance. Finally, the implications and limitations of the study were discussed.

In this paper, we modeled positive selection and negative selection that is developing process of cytotoxic T-cell that plays important role in biological immune system. Also, we developed change detection algorithm, which is very Important part in detecting data change by intrusion and data infection by computer virus. Proposed method is the algorithm that produces MHC receptor lot recognizing self and antigen detector for recognizing non-self. Therefore, proposed method detects self and intruder by two type of detectors like real immune system. We show the effectiveness and characteristics of proposed change detection algorithm by simulation about point and block change of self file.

센서 네트워크를 구성함에 있어서 센서 노드들의 자기위치 인식은 가장 기본이 되며 중요한 부분 중 하나이다. 이런 자기 위치 인식 기법 중에서도 소리를 이용한 기법은 정확도가 높은 장점이 있어 많은 연구가 있어 왔지만 기존의 방법들은 추가적으로 고가의 하드웨어를 이용하거나 중앙 집중식 연산을 함으로써 시스템의 부하가 크며 소리의 발생시간을 미리 계획하여야 한다는 단점이 있었다. 본 논문에서는 일반 음원감지 센서를 장착한 노드들을 이용하여 임의의 시간에 소리를 발생시키고 이를 감지한 각 개별 노드들이 독립적으로 자기위치 인식의 연산을 수행함으로써 에너지 소모를 줄이고, 시스템 설계의 비용은 낮추며 소리의 특성 또한 사용자의 요구에 맞게 설계하여 실용성을 높이는 자기 위치 인식 기법을 제안하고, 실제 구현을 통한 성능 분석을 제시한다.

실내의 완벽 주행이 주요 목적인 청소로봇은 자기 위치를 인식 할 수 있어야한다. 자기 위치를 제대로 인식하지 못하게 된다면 청소할 방을 모두 돌지 못하고 방 청소를 마치게 된다. 청소로봇이 상용화 되기 위해서는 저렴한 가격의 보드를 선호한다. 이것은 현재 나온 복잡한 계산을 요구하는 알고리즘을 사용하지 못하거나 사용하여도 속도가 느린 문제를 가진다. 영상 프레임 처리 속도가 느릴 경우 처리되는 동안 로봇이 움직이지 못하여 부드러운 움직임을 불가능하게 한다. 본 논문은 저사양의 하드웨어에서 자기 인식을 할 수 있는 시스템을 제안한다. 자기 인식을 하기 위해 처리 되어야 하는 전처리 과정과 전처리를 거친 데이터를 이용하여 자기 위치를 인식하도록 이동거리와 회전각을 계산하는 방법을 제안한다. 마지막으로 제안된 방법들을 이용하여 실제 이동 값과 비교, 분석한다.

The purpose of the study was to explore experience of self-awareness of nursing students in 'Counseling theory and practice' online class. Participants were 40 of nursing students learning of counseling theory subject in online, and Colaizzi's phenomenological method was used. The results were as follows. There were five theme clusters that 'find hidden my inner side', 'improve my healthy inner self', 'reflection of myself', 'recognize each others' different viewpoints' and 'create an aspiration and an impact'. Therefore, nursing students established self-awareness after learning of 'Counseling theory and practice' online class.

This study is focused on user awareness of avatar character in the cyber space. The purpose of this study is to investigate user preference toward avatar and test their awareness on it. The awareness of avatar is based on the applied degree of self-awareness, and also analyzed by factors using 3 elements such as loyalty, value and confidence in Maurice Wagner's study but self-projection was added to these three variables. The result shows that there is no significant statistical difference among response groups for age and sex classification but the preference and the value variables are significantly dependent on sex and age, respectively. There are strong correlation among each response variables for the awareness of avatar character and the loyalty and the preference variables are mostly correlated. The regression analysis shows that the preference of avatar is mostly affected by loyalty and thus the self awareness of avatar in the Cyberspace is proportional to user preference. It is shown that users do not awareness an avatar as a visual image but identify their avatar as an another selfness since they project themselves into those avatars.
