The purpose of research is analyzing the ecological variables on the effect of child care teacher's happiness. The data was collected by the survey of the happiness factors and ecological variables of child care teachers. The results are listed below. First, of organismic variable, the age and the educational background of child care teacher showed discrimination one's happiness. Second, of micro system variable, the marital status is the only thing that affect the happiness. Third, of meso system variable, the teachers who are highly interact on each other such as, child to teacher and parents to teacher are much happier than others. Finally, of the outside system variable, the teachers who are working at the better working environment and good quality of duty are much happier than others.

살아있는 유기체에 의해 분비되는 독소는 대부분의 경우 인간에게 유해하다. 가령 여름철 날것이나 오래된 음식에서 쉽게 식중독에 걸릴 수 있는데, 이는 주로 Clorustidium Botulinum이 만들어낸 보툴리눔 독소가 원인이다. 유기체에 의해 생성된 모든 독소는 단백질이며 이는 아미노산 서열로 나타낼 수 있다. 이를 통해 생물정보학 분야의 많은 연구자들이 많은 머신러닝 기술을 통해 단백질의 독성을 예측할 수 있었다. 최근 몇 년 동안 SVM를 사용하는 BTXpred와 CNN을 사용하는 ToxDL과 같은 모델이 각각 박테리아와 동물 독소의 독성을 예측하기 위해 제안되었다. 시대가 변함에 따라 BERT와 같은 성능이 더욱 뛰어난 모델이 시퀀스 분류를 위해 도입되었다. 본 논문은 독성 단백질을 분류를 위해 ProtBERT를 사용할 경우 이의 성능을 보여주고자 한다.

The purpose of this study aimed to examine the effects of ecological systems factors on childhood depression. A total of 2,119 children data from 2013 Korean Children & Youth Panel Survey(the fourth wave)were used in this study. The results of hierarchical regression showed the most ecological systems factors; organisms(child's gender, aggressiveness, attention problems), microsystems(parental neglect, parental abuse, good relationships with friends), exosystem(supportive community environment); had effects on depression. The most influential factors were child's aggressiveness, parental abuse, good relationships with friends, supportive community environment. Finally, this study suggested some implications for practical intervention and further research in childhood depression.

Kojic acid, a fungal metabolite produced by some species of Aspergillus and Penicillium, was found to induce chromosomal aberrations in Chinese hamster ovary cells in the presence or absence of the rat liver homogenate (59 mix). All categories of chromosomal aberrations increased with increased doses of kojic acid. Based on the this result, kojic acid was assumed to be a kind of mutagens. On the potential toxicity of this compound it becomes evident that kojic acid would not be used as a food additive at this time.

The Purpose of this study was to investigate the ecological variables on adolescent's sociometric popularity. Independent variables were organism(sex, age, aggression, self-esteem, impulsiveness, prosocial behavior, dominance), microsystem(parenting style, family support, friends relationship, teacher support), mesosystem(family-peer relationship, family-school relationship), and exosystem(positive community environment, social support of extended family, school's policy). The subjects were 835 - 1st and 2nd graders of two middle and two high schools in Daegu. Adolescent's sociometric popularity and ecological variables were measured with questionnaire. Adolescent's sociometric popularity was measured with sociometric popularity questionnaire. Organism variables were measured with sex, age, aggression, self-esteem, impulsiveness, prosocial behavior and dominance questionnaire. Microsystem variables were measured with parenting style, family support, friends relationship and teacher support questionnaire. Mesosystem variables were measured with family-peer relationship and family-school relationship questionnaire. Exosystem variables were measured with positive community environment, social support of extended family and school's policy questionnaire. The data analyzed by frequency, percentage, mean, cronbach's $\alpha$, and multiple regression. The major findings were as follows: First, adolescent's sociometric popularity was affected by age, overt aggression, academic self-esteem, social self-esteem, and impulsiveness of organism variables. Second, adolescent's sociometric popularity was affected by mother's affectional parenting, mother's control parenting, and attachment to friends of microsystem variables. Third, adolescent's sociometric popularity was affected by family - peer relationship and family - school relationship of mesosystem variables. Fourth, adolescent's sociometric popularity was affected by appraisal support of extended family, after-school activity, and circle activity of exosystem variables.

This research intended to investigate, from an ecological perspective, significant predictors affecting school life satisfaction. The subjects were 312 students(2nd grade) of commercial high school in Kyonggido. Data collected by questionnaire survey were analyzed by SPSS Win 22.0 and descriptive statistics, correlation analysis, hierarchical linear regression, and stepwise regression were conducted. There were 21 independent variables: 8 organism variables (self-competence, interpersonal skills, internal control, mood awareness, emotional expression, empathy, emotional regulation, emotional capability), 9 microsystem variables(school variables: the relationship with teachers, school learning, classroom climate, school welfare facilities, school environment/peer variables: peer relationship/family variables: family functioning, education level of fathers, economic status), 2 mesosystem variables(parent-teacher relationship, parent-children's peer relationship), 1 exosystem variables(satisfaction with Korean educational system), 1 macrosystem variables(Korean's primal belief in educational achievement). The results are as follows; the significant variables were the relationship with teachers, satisfaction with Korean educational system, peer relationship, emotional capability, parent-teacher relationship($R^2=45.3%$); and the effect of microsystem was the strongest($R^2=35.7%$). This research is meaningful of analyzing school life satisfaction of commercial high school in terms of ecological perspective.

디지털 삶에서 인간들은 더 이상 보호막으로써의 건축 환경이 아닌 함께 상호작용 할 수 있는 감성반응 환경을 요구한다. 즉, 실내 공간은 사람들의 요구를 충족시키거나 사람들의 기분을 만족시키기 위해 건물이 마치 살아 있는 유기체처럼 쉬지 않고 변하는 공간이다. 그러나 건축공간의 물리적 특성의 한계에서 유동적인 감성반응 환경의 요구를 충족시키는 데에는 많은 한계점이 따른다. 그래서, 본 연구에서는 이러한 한계점을 극복하기 위해 디지털 환경을 이용한 가상공간에서 실행하였다. 이는 실제공간에서의 시행착오를 줄일 수 있을 뿐만 아니라 빠른 시간 내에 인간의 반응을 연구할 수 있다. 특히, 본 연구에서는 감성반응의 실내배색에 의해 실내공간에서의 디지털 벽면의 디자인을 가상공간에서 개발하여 거주자의 감성 반응을 평가하는 것을 연구 목적으로 두었다. 이와 같은 거주자의 감성반응형 환경 디자인은 미래의 디자인의 패러다임이 될 것이다.

Housekeeping genes are expressed in cells of all organisms and perform basic cellular functions such as energy generation, substance synthesis, cell death, and cell defense. Accordingly, the expression levels of housekeeping genes are relatively constant, and thus they are used as reference genes in gene expression studies, such as protein expression and mRNA expression analysis of target genes. However, the levels of expression of these genes may be different among various tissues or cells and may change under certain circumstances. Therefore, it is important to select the best reference gene for specific gene expression research by exploring the stability of housekeeping gene expression. This review summarizes housekeeping genes found in humans, chickens, pigs, and rats in the literature and estimates expression stability using geNorm, NormFinder, and BestKeeper software. The most suitable reference housekeeping gene can selected based on expression stability according to the experimental conditions of the gene expression study and can thus be applied to data normalization.
