Purpose: To compare postoperative outcomes according to surgical method in partially accommodative esotropia in patients over 4 years of age. Methods: We compared motor and sensory outcomes between conventional and augmented surgery in 66 patients. The postoperative follow-up period was at least 24 months. The formula for the amount of the rectus muscle recession was based on the distant angle deviation after hyperopic correction in the conventional group and the average amounts of the distant angle deviation with and without full correction of hyperopia in the augmented group. In addition, the conventional group was divided into 2 sub-groups to compare surgical outcomes. The A group consisted of patients who underwent surgery with the amount of surgical correction based on distant angle deviation after full hyperopic correction. The B group consisted of patients under the same condition after reduced hyperopic correction to achieve best corrected visual acuity (BCVA). Results: Among the patients who had an ocular alignment less than 10 PD, orthophoria was significantly higher in the conventional group than in the augmented group on the last follow-up. When comparing the 2 conventional sub-groups, the postoperative stereoacuity was better in group B than in group A. Among patients with a postoperative overcorrected alignment of more than 10 PD who underwent augmented surgery, 75% showed decreased postoperative stereoacuity compared to preoperative stereoacuity. Conclusions: In partially accommodative esotropia in patients over 4 years of age, conventional surgery compared to augmented surgery after reduced hyperopic correction is better in order to achieve BCVA for postoperative stereoacuity as well as ocular alignment.

Machine learning techniques using visual data have high usability in fields of industry and service such as scene recognition, fault detection, security and user analysis. Among these, user analysis through the videos from CCTV is one of the practical way of using vision data. Also, many studies about lightweight artificial neural network have been published to increase high usability for mobile and embedded environment so far. In this study, we propose the network combining the object detection and classification for mobile graphic processing unit. This network detects pedestrian and face, classifies age and gender from detected face. Proposed network is constructed based on MobileNet, YOLOv2 and skip connection. Both detection and classification models are trained individually and combined as 2-stage structure. Also, attention mechanism is used to improve detection and classification ability. Nvidia Jetson Nano is used to run and evaluate the proposed system.

Recently, increasing one-person households, especially in the young generation, is one of the most important issues reflecting changes in the Korean family and society. The purpose of this study is to examine gender differences in life time use of one-person households aged 25 to 39, comparing with husband-wife couples of the same ages, and to investigate the determinants of subjective time poverty. Data are from the 2014 Life Time Survey by Statistics Korea. The major results are as follows. First, gender differences in time use of single youths were found in home management hours on weekdays. Female one-person householders spent more time in home management than their male counterparts, while male one-person householders spent more time in home management than young husband-wife groups. In addition, a much larger gender difference was found between young husbands and wives. Second, different effects on the subjective time poverty were found in both the groups. Based on these results, the implications for several specialized education and social programs for male and female one-person householders used in the local healthy families support centers are provided.

Brown tumor is a bone disease that arises in the setting of increased osteoclastic activity and fibroblastic proliferation in the involved bone. It is well recognized as serious complication of hyperparathyroidism. Brown tumor is uncommon, and brown tumor with secondary hyperparathyroidism resulting from chronic renal failure has rarely been reported. We recently experienced a case of a 28-year-old Korean woman with chronic renal failure caused by chronic glomerulonephritis, on hemodialysis for nine years. She has been hospitalized with left shoulder pain for two years. Image studies showed multiple cystic masses, and both suspicious marked thinning and partial destruction of the cortex on the head of the left humerus. Histopathologic analysis of the mass lesion showed a fibrotic capsule, hemosiderin pigmentation, and giant cell, all characteristic of brown tumor. A subtotal parathyroidectomy was done without surgery of the bony lesion (brown tumor), with successful results. We report this case with a brief review of the literature.

The life of middle-aged one-person households is rising as one of the most important family policy issues in Korean society. In Japan, even in multi-person households, the issues of middle-aged sons and daughters living with their old parents have been a concern. Data are from the 13^th wave of the Korea Welfare Panel Study analyzing 482 middle-aged singe males regardless of their past marital status. The purpose of this study is to investigate the effects of human capital and social capital on the life satisfaction of middle-aged single persons by comparing one-person and multi-person households, respectively. Major results were as follows: First, the level of human capital of one-person households of middle aged males was lower than their counterparts in multi-person households. Second, the level of social capital in the group of divorced or widowed, nonhouseholder middle-aged males in multi-person households was lower than their counterparts in one-person households. Third, the effects of human capital and social capital on life satisfaction was significantly different by their marital status and household types in the group of middle-aged single males. Based on the results, policy implications on the community programs for middle-aged males including not only one-person households but also multi-person households were discussed.

본 연구에서는 연구자로서 참여한 초등학교 초임 교사가 과학수업에서 경험한 어려움을 분석하여 교육대학의 양성과정이 과학수업에 미치는 영향을 알아보고자 하였다. 실제 초등학 교 교사의 과학수업에 끼치는 교육대학의 영향을 구체적으로 알아보기 위해 수업을 실시한 연구자(이하 수업교사)가 6개월 동안 진행한 과학 수업 관련 자료 및 과학 수업 일지와 교육 대학에서 경험한 양성과정 관련 자료들을 수집·분석하였다. 수업전문성 기준을 수정한 분석 틀을 바탕으로 과학교육전문가와 현직 교사들의 피드백을 받아 분석한 결과, 다음과 같은 결 론을 도출하였다. 첫째, 교육대학의 양성과정은 수업 진행과 관련된 기술적 측면보다는 교과 내용지식 및 교육학 지식과 같은 교사로서의 기본 역량을 신장시키는 데 많은 도움을 주었 다. 초임 교사인 수업교사는 과학 수업과 관련하여 지식의 부족보다는 적절한 교수·학습 방 법을 선정하고 실행하는 과정에서 어려움을 느끼고 있었다. 또한 교육대학의 환경과 초등학 교 현장의 차이로 인하여 관련 지식 및 경험이 있어도 수업을 진행하는 과정에서 어려움을 겪고 있었다. 둘째, 교육대학의 양성과정은 수업에 대한 교사의 가치관 및 과학 교과에 대한 교육관 형성에 많은 도움을 주었다. 수업 교사는 과학 수업과 관련하여 탐구 수업과 적절한 교수·학습 자료를 개발하거나 선택하는 것의 중요성을 깊이 인지하고 있으며 이것이 교육대 학에서의 양성과정에 의한 영향이라고 생각하고 있었다. The purpose of this study is to understand the influence of curriculums in the university for the pre-service teacher training course on a novice elementary school teacher``s science teaching based on the researcher``s teaching experience in science classes. The various materials and data have been collected, such as the teaching journals written for 6 months, data from the science classes and experience from curriculums in the university. Using the analysis tool modified from the standard of science teaching professionalism and with the feedback from science teaching specialists and elementary school teachers, the analysis of the collected materials and data results in two conclusions. Firstly, the curriculums in the university are much helpful in building the knowledge than in achieving the technical skill of teaching. It is inferred from the researcher``s experience that it is difficult to well proceed the science class even with relevant knowledges, such as contents and pedagogical knowledge, because of the gap between teaching activity in the elementary school and the lessons learned from the university. Secondly, the curriculums in the university help to build the sense of values about teaching science. Because researcher recognizes that the inquiry and teaching-learning materials are important and all sense of value on it are from the curriculums in the university.
