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<sup>th</sup> 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.

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.

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.

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.

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.
