반도체 패키지의 마킹검사(marking inspection)를 위해서는 입력 영상으로부터 검사할 패키지의 정확만 위치 검출과 패키지 윗면에 나타난 제작사 로고, 문자, Pin1 딤플의 추출이 필수적이다. 본 연구는 마킹검사를 위한 선행 연구로 마킹검사를 수행할 때, 검사할 IC 패키지의 위치와 방향을 정확하게 검출하는 것을 목적으로 하고 있다. IC 패키지의 외곽을 구성하는 리드의 명도 값은 트레이의 명도 값과 큰 차이를 나타낸다. 그러나 IC 패키지의 방향을 나타내는 Pin1 딤플은 배경과 동일한 색상으로 다만 약간 오목하게 들어가서 명도 값의 차이가 미세하다. 이러한 두 가지 상이한 특징을 효과적으로 처리하기 위하여 적응적 다중 이진화 방법을 제시하였다. 76개의 명도 영상에 대한 실험 결과 제안된 이진화 방법은 매우 효과적이었으며, 이진화된 영상으로부터 IC 패키지의 정확한 위치 검출과 방향 확인이 가능하였다.

This study examined the effects of parental neglect/abuse perceived by child and community awareness of child on school life adjustment according to child gender. The participants were 2,219 sixth grade students(1,167 boys, 1,052 girls) in the third Korea Youth Panel Survey. The results of this study were as follows; First, boys perceived parental abuse more than girls and boys perceived community more positively than girls. Boys perceived more difficulty than girls in peer relationship adjustment. Second, parents' neglect and abuse perceived by boys showed negative correlation with school life adjustment and community awareness of boys showed positive correlation with school life adjustment. On the other hand, parents' neglect and abuse perceived by girls showed negative correlation with school life adjustment and community awareness of girls showed positive correlation with school life adjustment. Third, the less perceived parental neglect/abuse and the better perceived community, the better the boys and girls could have school life adjustment. The results of this study offers a fundamental data about the parental neglect/abuse and the community awareness which can improve the school life adaptation of a sixth grade students who are moving from a primary school to a middle school.

The purpose of this study is to investigate the effect of family relations on facility adaptation of the elderly. In January and February of 2018, a questionnaire survey was conducted on 5 ~ 6 elderly residents of each long-term care facility, and finally 353 data were used for analysis. The main results of the study were as follows: First, the adaptation level of the elderly was high. As for 'maladjustment of group behavior' and 'movement shock', the level of maladjustment is low as 2 points, and adaptation dimension such as 'accept of new residence' and 'making friend' is above the middle level. Second, the influence of family variables was more influential than the demographic characteristics of the elderly and the influence of the facility-related variables. Among them, the closeness with family is the most influential. Therefore, it is suggested that the elderly need active support and efforts to maintain the intimacy with the family from the entrance to the facility and the time after the entrance.

The purpose of this study is to investigate whether there are differences in adolescents' school adaptation according to the types of perceived parental attitudes and consistency. For this purpose, 586(306 girls) middle and high school students were surveyed about their perceived parental attitudes and school adjustment, and the differences were verified through multivariate analysis of variance (MANOVA). The results showed that the adolescents' school adaptation was different according to the types of parental attitudes. Affection - autonomy cohort group's school adjustment was significantly higher than the other groups. In addition, the hostility - control group were found to have lower adaptation level than the disagreement group. Based on this results, we discussed the importance and influences of parental attitude and suggested the directions of follow up studies on parenting attitude and adaptation.

The purpose of this study is to find the mediative effects of social capital in the effective path of the satisfaction of education welfare project on school adaptation, and to find out the path difference between elementary and middle school students. We surveyed 153 elementary and 124 middle school students in Gangwondo. These data analyzed by multiple group analysis of structural equation. Elementary school students realized that social capital has an effect on school adaptation. Middle school students realized that the satisfaction of education welfare project has an effect on school adaptation, and social capital has an effect on school adaptation. There is not a mediative effect of school capital on the effect of the satisfaction on school adaptation for two groups. Based on these results, implications to improve the school adaptation for elementary and middle school students were suggested.

The purpose of this study is to investigate the effect of applying a group art therapy program on self-esteem and stress for adolescents who are maladjusted to school. The subjects of this study were 6 school maladjusted adolescents enrolled in the second year of B middle school in A region, and the period was from May 12 to June 9, 2021, twice a week, for a total of 10 sessions of 60 minutes each. As a research tool, the Self-Esteem Scale(SEI) and the Person-In-The-Rain(PITR) were examined to observe the students. For data analysis, Wilcoxon test was conducted to examine the change in self-esteem, and the Person-In-The-Rain(PITR) was qualitatively analyzed to observe stress by two art therapists. The results of this study were first, that the group art therapy program had a significant effect on improving the self-esteem of adolescents and second, the group art therapy program was effective in reducing the stress. In conclusion, group art therapy can be seen to help improve self-esteem and reduce stress in school maladjusted adolescents.

The eyes of Nilaparvata lugens were examined for ultrastructural changes in the light and dark adapted states. Inspection of light microscope sections taken at similar levels of compound eyes from insects kept in light or darkness for periods up to 72 hors revealed some differences between light and dark adapted eyes. Using the electronmicroscope, in light adapted eyes the palisade layer was narrower than that in dark adapted eyes. The pigment granules still formed a ring around the palisade layer in the dark adapted eye but, they did not form a tight circle around the rhabdom. No constant difference was found between the diameters of the microvilli in light and dark adapted eyes. The pigment movements at the junction of the cone and the rhabdom took the effect on varying the pigment aperture at the tip of the cone in front of the rhabdom tip.

Purpose: The purpose of this study was to compare the radiation adaptive response (RAR) in peripheral lymphocytes (PL) of patients induced by Tc-99m MDP and Tc-99m DTPA scintigraphies. Materials and Methods: Lymphocytes from 45 patients (25 males, 20 females, mean age $44{\pm}18$ years) were collected before and after scintigraphies using 740 MBq Tc-99m MDP (n=22) or Tc-99m DTPA (n=23). Lymphocytes from 20 controls (12 males, 8 females, mean age $43{\pm}7$ years) were also collected. They were exposed to challenge dose of 2 Gy ${\gamma}-rays$ using a Cs-137 cell irradiator Number of ring-form (R) and dicentric (D) chromosomes was counted under the light microscope. From them a representative score, Ydr, was calculated as Ydr=(D+R)/cells. Adaptation index (AI) was defined as difference of Ydr between unconditioned and conditioned lymphocytes. Ydr was also measured after an administration of cycloheximide (CHM), a protein synthesis inhibitor, before challenge dose. Results: RAR was induced in both groups of patients. CHM abolished the adaptive response in both groups. AI of Tc-99m MDP group was significantly higher than that of Tc-99m BTPA group. Conclusion: Tc-99m MDP induced RAR was more prominent than those induced by Tc-99m DTPA.

The purpose of this study is to find out whether pre-service biology teachers' biological meanings of competition and adaptation is the same as everyday meanings to understand natural selection and evolution. Fifty three pre-service biology teachers answered written tests and thirteen of them were interviewed. The tests on general meanings on competition and adaptation, tests on biological meanings on competition and adaptation and tests on natural selection were administered. Questions on semi-structured interviews were composed of only biological meanings about competition and adaptation. Analyzing data through four steps, pre-service biological teachers' general meanings on competition and adaptation were compared with the definitions of Korean dictionary and compared with biological definitions. Pre-service teachers' alternative conceptions about biological competition and adaptation were classified and the alternative conceptual types were checked when explaining natural selection and evolution. They realized competition is battle for intention or purpose like everyday meaning of competition. However, they didn't realize adaptation happen in the population level. They thought that adaptation, like in everyday life meaning, is getting suitable to environment for survival on an individual level. By relating adaptation to evolution, they thought that long-lasting adaptation become evolution. This study has significance with respect to suggesting the alternative concepts of competition and adaptation based on effective evolution teaching from constructivism viewpoint and highlighting the importance of the concepts of biological competition and adaptation, which have been concerned rarely for a long time.
