The chestnut gall wasp, Dryocosmus kuriphilus $Y^{ASUMATSU}$, has been recently distributed and chestnut trees have teen seriously damaged by this insects in Korea. However, this insect pest has not been investigated in Korea. This paper gives an account of field and Laboratory observations on the seasonal occurrence and the life history of the chestnut gall wasp, and the damage of the chestnut trees by. its insects. This study was carried out at Chungchungpukdo, Kangwon-do and Kyungi-do in Korea, from 1961 to 1963, inclusive. 1. The Chestnut gall wasp (Dryocosmus kuriphilus $Y^{ASUMATSU}$) has one generathion per year and females are only known. 2. The adult wasps were observed from late June to late July with peak of wasp emergence about early and middle July. Most of new adult wasps were coming out from, the galls in the morning rather than the afternoon. 3. Each wasp produced auerage 198.5 eggs and about 4.89 eggs was observed in each bud of the chestnut tree. 4, The egg period of wasps was about 30 days and they were hatching from July to August. 5. The larval period of wasps were from middle of August to middle of next June and pupation took places about early June to middle of July. 6. The adult wasps were ovipositing into the buds and from early May next year, galls were growing. They caused stunting of growth and no fruiting or dying of the chestnut tries. 7. The first observation of the wasp was made at Chaechun of Chungchung-pukdo in 1958. Up to 1963 this insects are distributed in Kangwon-do, Kyunggi-do, north part of Chungchung-pukdo and north part of Kyungsangpukdo

The purpose of this study was to obtain baseline data of nutritional management for women's bone health according to age. This study was conducted through questionnaire, bone mineral density(BMD) measurement by DEXA and dietary survey by 24hr recalls to 134 adult women. Subjects were divided into three groups: young women group who aged 20-29(n=48), middle aged women group who aged over 30 and were pre-menopause(n=36), postmenopausal women group(n=48). The body fat percent of postmenopausal women group was the highest among the three groups. BMD of lumbar spine(L1-L2) were $0.93\;g/cm^2$ for young women, $0.97\;g/cm^2$ for middle aged women, and $0.88\;g/cm^2$ for postmenopausal women, respectively(p<0.05). BMD of femoral neck(p<0.05), trochanter(p<0.05), and ward's (p<0.001) were significantly decreased as age increasement. Drinking alcohol and skipping meals were significantly higher in young women groups than in the other groups, however frequency of doing regular exercise was significantly lower in young women groups. Young women group consumed the significantly higher amount of cereals(p<0.05), sugar and sweeteners(p<0.001), meats(p<0.01), eggs(p<0.01), milks(p<0.05) and oils(p<0.001) than middle aged and postmenopausal women. Also, energy(p<0.001), animal protein, (p<0.01), plant oil(p<0.001), animal fat(p<0.001), retinol(p<0.001), vitamin E(p<0.01), and cholesterol(p<0.001) intakes of young women were highest among the three groups. However, young women group consumed the significantly lower amount of dietary fiber(p<0.05), vitamin C(p<0.01), folate(p<0.05) and fruits(p<0.01) than the other groups. To summarized the our results, young women who were in still undergoing bone formation activity to develope peak bone mass, had more dietary habit and lifestyle problems than middle aged and postmenopausal women. The results of this study revealed that nutritional management and education for bone health should be emphasized in young women not only aged women.

Objective : Moyamoya disease (MMD) is a chronic cerebrovascular occlusive disease of unknown etiology. In addition, the neurocognitive impairment of adults with MMD is infrequently reported and, to date, has not been well described. We attempted to determine both the neurocognitive profile of adult moyamoya disease and whether a superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis can improve the neurocognitive impairment in exhibiting hemodynamic disturbance without stroke. Methods : From September 2010 through November 2012, 12 patients with angiographically diagnosed MMD underwent STA-MCA anastomosis for hemodynamic impairment. Patients with hypoperfusion and impaired cerebrovascular reserve (CVR) capacity but without evidence of ischemic stroke underwent a cognitive function test, the Seoul Neuropsychological Screening Battery (SNSB). Five patients agreed to undergo a follow-up SNSB test. Data from preoperative and postoperative neurocognitive function tests were compared and analyzed. Results : Five of 12 patients were enrolled. The median age was 45 years (range, 24-55 years). A comparison of preoperative to postoperative status of SNSB, memory domain, especially delayed recall showed significant improvement. Although most of the domains showed improvement after surgery, the results were not statistically significant. Conclusion : In our preliminary study, large proportions of adult patients with MMD demonstrate disruption of cognitive function. This suggests the possibility of chronic hypoperfusion as a primary cause of the neurocognitive impairment. When preoperative and postoperative status of cognitive function was compared, memory domain showed remarkable improvement. Although further study is needed, neurocognitive impairment may be an indication for earlier intervention with reperfusion procedures that can improve cognitive function.

Recently, the intercultural approach, which aims to resolve social conflicts in multicultural societies through cultural encounters and dialogue, has been actively discussed. Intercultural education aims to foster smooth relationships and improve communication skills through interactions among various cultural groups. Analysis of previous studies has revealed the need for research on intercultural civic education programs targeted at adults. Therefore, this study was designed to develop an intercultural citizenship education program and to analyze its effects. For the study, previous research on interculturalism, intercultural citizenship education, and intercultural citizenship education programs was comprehensively analyzed. The developed intercultural citizenship education program was categorized into five major themes: understanding oneself and others, racism and hate speech, overcoming conflict and discrimination, breaking away from prejudice and stereotypes, and the future of our country. Subsequently, the program was implemented with 64 total second-year middle school students, 37 in the experimental group, and 27 in the control group, at an accredited lifelong educational institution in M City, South Jeolla Province. To analyze the effects of the education, an intercultural competency scale was used. The results showed that the intercultural citizenship education program for adult students was effective in conflict management, respect, communication, and reflection competencies, all at a statistically significant level. Finally, the authors compared the study results with previous research and discussed the findings. Findings indicated the necessity of enhancing multicultural citizenship awareness among adults and expanding teacher training in intercultural education. The program effectively improved intercultural competence among adult students, highlighting the importance of tailored educational content and active participation in discussions. Future research should ensure a balanced gender ratio among participants.

This study aims to examine whether a parental neglect affects an adolescent's peer attachment and adult media immersion has a mediating effect. To achieve this goal, the first year of middle school panel of 'the 6th(2015) Korean Children and Youth Panel Survey(KCYPS)' was utilized. Using SPSS PROCESS Macro developed by Hayes, 'Bootstrapping' was employed to examine the significancy of the mediating effect on 563 objectives. According to the study, first of all, more parental neglect gave rise to less peer attachment. Second, the adult media immersion partly mediates the parental neglect and the adolescent's peer attachment. The practical implications of this results are below : First, parents' care and affection inside a home is necessary to formulate the healthy peer attachment of adolescent. Second, a parent education is important to prevent an adolescent's adult media immersion. Third, an adult media education for an adolescent is desired.

The present study investigated the relationship between adult attachment and depression and the moderating effects of social support in secondary school teachers. Survey data was collected from 231 secondary school teachers working at three middle and high schools in the Seoul and Gyung-gi areas. Correlation and hierarchical multiple regression analyses were used to test the relationships among the main variables, namely adult attachment, social support, and depression, and the three moderating effects of social support in the relationship between adult attachment and depression, respectively. The main results were as follows. First, each sub-dimension of adult attachment, namely dependent attachment, anxiety attachment, and close attachment, were significantly correlated with depression levels. All of the variables except senior support and dependent attachment were significantly correlated with depression. Second, social support had a moderating effect in the relationship between anxiety attachment and depression. Colleague and family support had moderating effects in the relationship between dependent attachment and depression though senior support did not.

Purpose: This study was conducted to investigate the prevalence and related factors of metabolic syndrome in postmenopausal adult women in South Korea. Methods: Data of 678 postmenopausal adult women aged 19 to 64 were collected from the Eighth Korea National Health and Nutrition Examination Survey in 2021 and analyzed by a complex sampling design using SPSS 20.1. Results: The prevalence of metabolic syndrome in postmenopausal adult women was 25.8%. The prevalence was 1.93 times (confidence interval [CI]=1.15~3.25, p=.014) higher for high school graduates, 2.55 times (CI=1.33~4.91, p=.005) higher for middle school graduates, and 2.90 times (CI=1.36~6.15, p=.006) higher for elementary school graduates, compared to college graduates. It was found that artificial menopausal women had 2.74 times (CI=1.18~6.38, p=.020) higher prevalence than natural menopausal women. In addition, women who perceived their health as bad were 1.90 times (CI=1.14~3.16, p=.014) higher than women who perceived their health as good, and women who did not muscle exercise more than twice a week had 1.87 times (CI=1.05~3.34, p=.034) higher prevalence than women who did muscle exercise. Conclusion: Therefore, in order to effectively prevent and manage metabolic syndrome in postmenopausal adult women, a focus must be placed on vulnerable groups to manage these factors.
