One of the major implications of women's movements seems to lie in the fact that it tends to promote women's consciousness-raising and, thus, heighten social status of women in general. It would be very much the case when discussion centers around the emergence of Korean women's movements in modern sense. Due to the socio-political atmospheres of the lathe 19th century Korean society, its basic characteristics owe to strong tones of patriotic nationalism under the slogan of "learning is might enough to deal with the imperialistic foreign powers of the time." As such, ever since the introduction of women's enlightenment movements of the time, Korean women's movements have provided for the advancement of egalitarian society. However, assessing the effectiveness of programs that are practiced by the existing women's organizations in Korea, it deserves mention in that most programs are for the adult female members, assuming it would only be applicable to those adults. In this regard, it can be said that the Korean Girl Scout organization has worked a unique role to make up such voids in women's movements - most programs developed and exercised by the Girl Scout are reserved for those young girls. For instance, special activities like social services, field campaigns, and international gatherings would definitely work a profound impact in the formation of gender-role stereotypes of the youth. The present study tries to examine the Korean Girl Scout movement being the case of women's movement organization. Discussion will cover such topics as; historical reviews of Korean Girl Scout movement, principal organizational goals and its practice in real life, and internal dynamics of members between "staffs" and the ordinary members themselves-on perceptions of the movement, evaluation of leaderships, and the future orientations of the Girl Scout, etc. Various research methods are employed. Book reviews, in-depth interviews, questionnaires, and participant observations are utilized, when the respective measurement is required. Major findings of the study can be summarized as follows: (1) Numbers of Girl Scout membership have declined since 1980, while revealing its utmost pick upto mid-70s. In terms of regional distributions of the members, both Seoul and Kyung-Nam Branches are the most prosperous. Whereas commemoration ceremonies and camping works are considered most impressive programs, membership trainings and field works are the lowest. About 70 percent of the members show their length of activities in Girl Scout less than one year. Most members are involved in the activities based on self-decision in order to have social services, club memberships, or self actualizations. They are satisfied with most of the programs, especially when participating in the social service programs. (2) As for the staff members, about half of the leaders in the headquarters are newly appointed. Whereas majority of the 'field' staffs are young (in their 20s, or 30s), other leaders are considered old (most of them are in their 40s, 50s, or 60s). Half of the leaders are involved in the activities for less than 5 years. They are recruited by either colleagues' or office seniors' recommendations. Reasons to participate in the movement are to have self-actualized or to have opportunity for social services. All in all, leaders are satisfied with the Girl Scout activities mainly because they can see their youth members progressing and developing. (3) Several issues for the better organizational managements seem to be related. prevalence of aspirational differences between leaders and members tends to cause psychological burdens. Other problematics such as lack of free communication networks, tensions due to cohort differences, authoritarian leadership styles, and financial difficulties would hinder Girl Scout movement more promising and popular to all. Based on the research findings, two major suggestions might be in order. First, underlying rationales of the Girl Scout movement should be reoriented. A special emphasis on the creation of self-supportive 'androgynous individuals' would be the case (in this regard, an intensive program targeted for those pre-school-aged members would be the most effective). As a way to achieve the strategic reformulation, reliance on the interdisciplinary program (for example, coordination with the university) will be one possibility. Secondly, an organizational management should be sufficiently considered. provisions (tangible and intangible) for the 'field leaders' being the key leader group in the Girl Scout movement should be afforded enough to keep their participations voluntary and continuous.

The purpose of this study is to determine through what media and how much ecological variables affect the ego-identity formation among adolescents. In particular, their media and amount of influence are analyzed according to sex and age of the youths. For this investigation, spousal relationship, socioeconomic status of the family, peer relationship, and student-teacher relationship are taken for external variables; parental expectation from their childrens education, parental attitude to child rearing, family support, peer support, and ego identity for internal variables. A random sample of 767 secondary school male and female students and 767 parents was investigated through questionnaires for the nine variables mentioned above. The results of the questionnaires were analyzed by covariance structure analysis, and path analysis and Lisrel-pc 8.03 statistical analysis program were applied to determine cause-and-effect relations among the variables. After reviewing previous studies, the following conclusions were derived: First, in regard to the media through which these ecological variable are affecting the ego identity development, female adolescents are susceptible to spousal relationship, socioeconomic status of the family, and parental attitude to child rearing, parental expectation from their childrens education, parental attitude to child rearing, and peer support, but male adolescents are not noticeably affected by these variables. While parental expectation from education affect peer support positively for male adolescents, these variables have no effect on female adolescents. Second, with respect to sexual differences, female adolescents are affected by familial factors more notably than male adolescents are. Third, in regard to the media through which these ecological variable are affecting the ego identity development, the middle school students are susceptible to spousal relationship, parental expectation from their childrens education, parental expectation from their childrens education, and peer support, but the high school students are not noticeably affected by these variables. While socioeconomic status of the family, and peer support affect peer support, and the ego identity positively for the high school students, these variables have no effect on the middle school students. Finally, as for the age differences, it was found that as they grow older, student-teacher relationship and peer support have a stronger influence than familial factors do.

Objective: The purpose of this study was to understand the differences in masseter muscle (MM) between the shifted and non-shifted sides in facial asymmetry patients, and the changes shown by MM after mandibular surgery. Methods: Pre- and post-operative CT scans were performed on 12 Class III patients with facial asymmetry who were treated by intraoral vertical ramus osteotomy and 10 subjects with normal occlusion. Using the V-works 4.0 program (Cybermed, Seoul, Korea), 3-dimensional images of the mandible, and MM were reconstructed, and evaluated. Results: In the asymmetry group, the MM angle between the shifted and non-shifted sides was only significantly different (p < 0.05). Compared with normal occlusion, the asymmetry group showed a significantly smaller volume and maximum cross-sectional area in both sides of MM (p < 0.05). After mandibular surgery, the angle of MM (p < 0.01) and differences in angle between the shifted and non-shifted sides of MM (p < 0.05) were significantly decreased. The thickness in the maximum cross-sectional area was significantly increased (p < 0.01). After surgery, MM in facial asymmetry patients was similarly changed to those in the normal occlusion group except for widths. Conclusions: MM in facial asymmetry was definitely different from those in normal occlusion. However, this study suggests that MM changed symmetrically in conjunction with the mandible after proper mandibular surgery. 안면비대칭 환자에서 하악 우각부위의 연조직 형태에 결정적 영향을 미칠 수 있는 교근의 성상에 대한 평가는 경조직의 분석과 더불어 중요하다. 교근은 수술로 인한 하악의 후방이동 시 가장 많은 영향을 받는 구조 중 하나이며, 수술 후 교근의 상태는 환자의 저작력과 하악 우각부 외형에 영향을 줄 수 있다. 본 연구는 안면비대칭을 가진 골격성 III급 부정교합자의 편위, 비편위측 교근의 형태학적 차이와 하악골 후퇴술 이후 양측 교근의 변화를 비교 분석하고자 하였다. 또한 안면비대칭의 개선 전, 후 교근을 정상교합자와 비교하여 비대칭의 수술이 교근에 미치는 영향을 알아보고자 하였다. 안면비대칭으로 진단된 환자 12명의 양악수술 전후의 3차원 CT 영상과 정상교합자 10명의 3차원 CT 영상에서 하악골과 교근을 계측, 분석하였다. 연구 결과 비대칭군에서 교근의 편위, 비편위측 모두 정상교합군에 비해 부피가 작고, 최대 단면적 부위가 좁은 것을 알 수 있었으며, 편위, 비편위측의 교근의 주행각도 차이와 최대단 면적 부위에서의 두께 차이가 정상 교합군보다 크게 나타났다. 양악 수술 전, 후에 교근의 주행각도는 유의성 있게 감소하였고, 편위, 비편위측 각도의 차이도 감소하였으며, 최대 단면적 부위에서의 교근의 두께가 유의성 있게 증가하였다. 비대칭 수술 후 좌우 교근은 너비를 제외하고는 정상 교합자와 유의차 없게 변화하였다. 이상의 연구 결과, 안면비대칭 환자는 교근의 성상이 분명히 정상 교합자와는 다르지만, 적절한 수술 후에 경조직뿐만 아니라 교근도 정상범주로 변화하였음을 알 수 있었다.

Autophagy is a highly regulated cellular mechanism that results in the bulk degradation process and which seems to be implicated in a variety of physiological and pathological conditions relevant to Alzheimer's disease (AD). Also, it has been suggested that the large part of autophagy is mediated by Light Chains 3 (LC3). Despite research suggesting an association between AD and autophagy, many issues remain to be addressed. To determine the relevance between autophagy and AD, we evaluated amyloid beta (Aβ) toxicity either in SH-SY5Y cells transfected with only EGFP or the cells exogeneously transfected with EGFP-LC3, mediating autophagy easily by overexpressed LC3. Without treatment of Aβ, the cell viabilities were quietly similar in both kinds of cells. The cell viability was decreased significantly in LC3 overexpressed cells. Consistently, more increased oxidative stress was detected in LC3 overexpressed cells. These results suggest that autophagy enhanced Aβ toxicity by way of increasing oxidative stress at least in part. This study will be of help to understand the role of autophagy in neurodegenerative diseases.

The purpose of this study was to evaluate the mobility and ratio of the bone-implant contact (BIC) of a sandblasted, large grit and acid-etched (SLA) orthodontic micro-implant. Methods: Ninety-six micro-implants (48 SLA and 48 machined) were implanted in the upper and lower buccal alveolar bone, and palatal bone of four beagle dogs. Two weeks after surgery, orthodontic force (150 - 200 g) was applied. Two beagles were sacrificed at 4-weeks and the other two at 12-weeks. Histomorphometric comparisons were made between the SLA experimental group and the machined micro-implant as a control group to determine the ratio of contact between the bone and implant. Micro-implant mobility was also evaluated using Periotest. Results: Periotest values showed no statistically significant difference in the upper alveolar and palatal bone between groups except for the lower buccal area. BIC in the upper buccal area showed no significant difference between groups both at 4-weeks and 12-weeks. However, both the groups showed a significant difference in BIC ratio in the rest of the experimental areas between 4 weeks and 12 weeks. The experimental group showed active bone remodeling around the bone-implant interface compared to the control group. Conclusions: There were significant differences in the BIC and the Periotest values between the surface-treated and machined micro-implants according to bone quality in the early stage. 본 연구는 비글견에 식립된 sandblasted, large grit and acid-etched (SLA) 표면처리된 교정용 마이크로임플랜트와 평활면 마이크로임플랜트에 교정력을 가한 후 시간 경과에 따른 동요도와 골접촉률의 차이를 규명하기 위해 시행되었다. 비글 성견 네 마리를 이용하여 상, 하악 협측과 구개측 골에 대해 SLA 표면처리된 표면처리군 48개, 평활면의 비처리군 48개의 마이크로임플랜트 96개를 식립하고 2주의 치유기간 후 교정력(150 - 200 g)을 지속적으로 가했으며 식립 4주 후에 두 마리를 희생시키고, 12주 후에 나머지 2마리를 희생시켰다. 표면처리군과 비처리군 간의 마이크로 임플랜트의 동요도와 골과 임플랜트 간 접촉률을 조직학적인 측면에서 측정 비교하여 다음과 같은 결과를 얻었다. 상악 협측과 구개측에서는 표면처리군과 비처리군의 동요도에서 유의성 있는 차이가 없었으나 하악협측에서는 표면처리군이 유의하게 안정적인 동요도를 보였다. 마이크로임플랜트와 인접골 간 접촉률은 상악 협측에서는 4주와 12주 모두 표면처리군과 비처리군 간에 유의한 차이가 없었으나 하악 협측과 구개측의 경우 4주와 12주 모두 표면처리군이 비처리군에 비해 유의하게 높은 접촉률을 보였다. 표면처리군은 비처리군에 비해 임플랜트 주변에서 활발한 골개조가 관찰되었으며 모든 군에서 이물반응은 관찰되지 않았다. 본 연구를 통해 SLA 표면처리된 마이크로임플랜트는 평활면 마이크로임플랜트에 비하여 식립 초기에는 식립 부위에 따라 유의하게 높은 인접골 간 접촉률과 동요도의 안정성을 보임으로써 다양한 크기와 방향의 교정력의 적용이 가능할 것이라 생각한다.

김청운(Chung Woon Kim),김승우(Seung Woo Kim),유재은(Jaeeun Yu),정승아(Seung Ah Chung) 대한안과학회 2022 대한안과학회지 Vol.63 No.11

목적: 수술이 필요한 정도의 간헐외사시를 처음 발견한 사람이 안과의사인 군과 부모를 비롯한 비전문가인 군에서 간헐외사시 특징이다른지 알아보고자 하였다. 대상과 방법: 평균 5.9 ± 1.4세에 20프리즘디옵터(prism diopters, PD) 이상의 간헐외사시로 진단받은 환아 218명의 의무기록을 후향적으로 조사하였다. 간헐외사시 최초 발견자가 안과의사인 군과 비전문가인 군으로 나누어, 프리즘교대가림검사로 측정한 실제사시각과 반투명가리개로 가리고 촬영한 사진을 바탕으로 전문의 2명이 평가한 사진사시각, 간헐외사시 분류, 융합조절, 입체시, 억제, 구면렌즈대응치를 비교하였다. 결과: 평균 원거리사시각이 25.8 ± 6.8 PD인 간헐외사시를 41명(18.8%)은 안과의사가, 177명(81.2%)은 비전문가가 처음 발견하였다. 사시안의 구면렌즈대응치가 안과의사군에서 비전문가군에 비해 근시인 것(-0.77 ± 1.59 디옵터[diopters, D] vs. -0.19 ± 1.48 D, p=0.03)을 제외하고는 두 군 간 차이가 없었다. 두 군에서 나이와 사시안의 구면렌즈대응치를 짝지은 39쌍을 비교하면, 안과의사군에서 원거리, 근거리 실제사시각이 비전문가군에 비해 작았지만(24.0 ± 6.8 PD vs. 28.5 ± 6.4 PD, 26.9 ± 6.6 PD vs. 31.0 ± 6.4 PD, p<0.01), 사진사시각을 비롯한 다른 특징은 차이가 없었다. 결론: 수술이 필요한 정도의 간헐외사시라도 사시각이 작거나 근시가 동반된 경우 안과의사가 검진을 통해 처음 발견하는 경우가 많았다. Purpose: To determine whether the clinical features of intermittent exotropia (IXT) needing muscle surgery were different in the ophthalmologist-detected and non-specialist-detected groups (including parents). Methods: Medical records of 218 children (mean age: 5.9 ± 1.4 years) with IXT of ≥ 20 prism diopters (PD) were reviewed retrospectively. The angles of deviation were measured using the prism and alternate cover test and assessed by two ophthalmologists using photographs with a translucent occluder (photographic angle). The IXT subtype, fusional control, stereopsis, suppression, and spherical equivalent (SE) were compared between the ophthalmologist-detected and non-specialist-detected groups. Results: Mean 25.8 ± 6.8 PD of distant angle of IXT was first detected by the ophthalmologist in 41 patients (18.8%) and the non-specialists in 177 patients (81.2%). The deviated eye was more myopic in the ophthalmologist-detected than non-specialist- detected group (-0.77 ± 1.59 diopters [D] vs. -0.19 ± 1.48 D, p = 0.03). There were no other differences between the two groups. A comparison of 39 age- and non-dominant eye SE-matched pairs demonstrated that the measured angles for distant and near fixation were smaller in the ophthalmologist-detected than non-specialist-detected group (24.0 ± 6.8 PD vs. 28.5 ± 6.4 PD and 26.9 ± 6.6 PD vs. 31.0 ± 6.4 PD, respectively, p < 0.01), while the remaining characteristics, including the photographic angle, were similar. Conclusions: In cases with small angles of deviation or myopia, IXT with angles requiring surgical correction were commonly first detected by ophthalmologists during examinations.
