  • 초기의 웜은 감염 및 확산의 신속성을 중요시하였으나, 생존성은 고려하진 않았다. 하지만 보안도구(Anti-worm)의 발달에 따라 2004년 이후 대규모의 웜 확산에 의한 피해가 보고되지 않고 있다. 이에 웜도 보안도구를 회피하는 자기방어(Self-Defense) 기법을 개발하여 생존성을 증가시키면서 진화하고 있다. 본 논문은 현존하는 웜 자기방어 기법과 그 한계를 분석한 후 행동기반 탐지 기법을 우회하는 자기방어 기법을 제안하도록 하겠다.

  • This study surveyed a total of 1,322 radiation technologist in health care institutions throughout Korea. This is a comparative study conducted on the levels of protective behavior against the harmful effects of radiation in heath care institutions which indicated that university hospitals and general hospitals showed higher level of protective behavior than for medical practitioners. This study found university hospitals have the following 7 characteristics to manage protective behavior against the harmful effects of radiation, protective environment, self-efficacy by distinction of task, self-efficacy, expectation of the protective behavior, the number of patients, level of the education related to the protection of the harmful effects of radiation and protective attitude. While general hospitals have the following 3 characteristics protective environment, expectation of the protective behavior and protective attitude. Hospitals have the following 4 characteristics protective environment, expectation of the protective behavior, protective attitude and self-efficacy. and medical clinics have characteristics protective environment.

  • 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.

  • This study was designed to identify the knowledge, perception, self-efficacy, and performance on radiation protection among perioperative workers in terms of radiation protection. The factors affecting the performance of radiation protection were identified, and provide basic data for the development of an effective radiation protection education program. The sample was comprised of 166 perioperative workers who agreed to participate in this descriptive study. Data analysis was performed using the t-test, analysis of variance, Pearson's correlation, and multiple regression analyses on the SPSS 23.0 Program. The average time of radiation exposure was 3-4hoursThe radiation protection education experience was 11.4%. The average score of radiation protection knowledge was $8.61{\pm}2.51$; the perception was $4.59{\pm}0.64$; and the performance was $2.99{\pm}0.90$ There was a significant difference in the degree of radiation defense knowledge and performance among the general characteristics (p <001). Knowledge of radiation protection was correlated with the perception. The performance of radiation protection was correlated with the knowledge. The knowledge and perception of radiation protection behaviors should be increased to improve radiation protection performance. Therefore, it is important to promote the performance of radiation protection behaviors by improving the perioperative workers' knowledge of radiation protection through reinforcing radiation-related education.

  • This study aimed to identify the associated factors of protective behaviors for radiation exposure among some radiology technologists using the Health Belief Model. The subjects of the study were 541 radiology technologists working at hospitals or clinics in Honam Province. Using the SPSS version 18.0 program, data were analyzed using a t-test, ANOVA, Pearson's correlation analysis, and hierarchical multiple logistic regression analysis. To modify the factors, the performance of subjects who had a higher level of education and nuclear medicine rooms were higher than those who worked in simple radiography rooms. The radiation protective behaviors performance of the subjects who had more exercise, medium-level stress, and worked in higher-quality protection facilities was higher. Regarding the personal perceptions, the cues to action (β=.292, p=.0001), and perceived seriousness (β =.075, p=.010) were factors that had effects on the performance of radiation protection behaviors. Regarding the likelihood of action, the benefits (β=.168, p<.0001), self-efficacy (β=.148, p=.007), and the performance of protective behaviors were higher. In conclusion, protection education as a cue to action should be provided to stimulate protective behaviors, and the benefits of protective behaviors should be emphasized. To increase the performance of protection behaviors, self-efficacy should be enhanced, and the subjects are offered appropriate information that helps perceive seriousness.

  • 생체 면역 시스템은 외부의 물질로부터 생명체를 지켜주는 방어 시스템으로 자기와 구별되는 외부 물질을 인식하여 생명체를 지켜준다. 본 논문에서는 이러한 생체 면역 시스템의 자기와 비자기를 구분하는 특징을 컴퓨터에 적용해서 자기(Self) 파일과 구분되는 비자기(Nonself) 파일을 인식 가능하도록 생체 면역 시스템의 T세포를 모델링하였다. 모델링한 T세포는 자기를 인식하는 MHC인식부와 비자기를 인식하는 항원인식부로 구성되어 있으며, 자기-비자기 검사를 요하는 파일과의 매칭을 통해 자기-비자기를 구분한다. MHC인식부와 항원인식부로 구성된 T세포의 자기-비자기 인식률이 항원인식부만을 사용한 자기-비자기 인식률에 비해 높아짐을 입증하였다.

  • 최근 환경변화와 국제교류의 확대로 인하여 예전에는 문제가 되지 않았거나, 보이지 않았던 해충들이 문제해충화 되어 우리 주변에서 정원수나 조경수에 피해를 주는 해충들이 있다. 이들은 크게 3가지로 분류되는데 (1)환경의 변화에 의한 잠재해충과 문제해충화 (2) 인간의 욕심에 의해 대면적 식재로 인한 해충의 기회 확대 (3) 국제교류 확대로 인한 외래 해충의 침입 으로 나눌 수 있다. 이번 호에서는 환경변화에 의한 해충의 발생으로 환경스트레스에 의해 식물 자체 내의 방어체계가 무너지면 어떤 특정종이나 일반 해충이 대발생하는데 식물자체 환경 스트레스에 관계하는 jasmonate의 작용 저해, 식물이 자기방어를 위해 분비하는 타감물질(allelopathy)의 분비 억제, 초식성 곤충으로부터 산란억제를 위한 연모의 부족 등 해충의 대발생을 야기 시키는 경우도 있다. 또한 지구온난화로 인한 각종 해충의 대발생은 현재 전 세계적으로 문제가 되고 있다. 기온의 상승으로 곤충의 발육이 빨라져 화기 수가 증가한다거나, 포식자와 피식자의 상호작용의 연결고리가 깨어지는 등 각종 원인으로 인한 최근 발생한 해충을 기술하였다.

  • The purpose of this study is to investigate moderating effect of psychological flexibility on impact which students feel ambivalence over emotional expressiveness in interpersonal relationships. In summary, the results are as follows. Self-defence ambivalence is strong negative influence on subject well-being but concerned-relation ambivalence is not affect at subject well-being. Also, moderating effect of psychological flexibility in concerned-relation ambivalence is not appear on subjective well-bing while self-defence ambivalence is shown moderating effect of psychological at subjective well-being. These results are mean that concerned-relation itself contains psychological flexibility role and psychological flexibility is negative influence on self-defence ambivalence and positive influence at subjective well- being. Moderating effect of psychological flexibility is shown that as important role subjective well-being. So students will need to help accommodate an active experience in the field allow s college students to raise their own psychological flexibility.
