Purpose: To investigate the efficacy and detection rate of disease in the customized eye examination program. Methods: We reviewed the medical charts of 122 patients who have conducted the customized eye examination program from January 2018 to January 2019 in Kim’s Eye Hospital retrospectively. The customized eye examination program consisted of visual acuity test, intraocular pressure measurement, color vision test, slit-lamp examination, visual field tests, fundus photography, spectral domain optical coherence tomography (Cirrus HD-OCT, Zeiss), Optical Quality Analysis System (OQAS, Visiometrics, Terrassa, Spain), and dry eye test (LipiView II TearScience, Morrisville, NC, USA). The rate of newly diagnosed diseases and vision-threatening disorders including glaucoma and retinal disorders were calculated. Results: A total of 122 patients (46 males and 76 females, mean age; 47.8 ± 14.0 years old, from 22 to 85 years) were included. Nine patients (14 eyes) had a poor vision of less than 0.8. Newly detected diseases were found in 17 patients (13.9%), and among them, 10 glaucoma (8.2%) and retinal disorders (5.7%) were included. When it comes to glaucoma, 7 patients were diagnosed with definite glaucoma with visual field loss, and 3 patients had preperimetric glaucoma. Retinal disorders were composed of 5 epiretinal membranes, 1 diabetic retinopathy, and 1 central serous chorioretinopathy. Conclusions: Various diseases were identified by the customized eye examination program, and vision-threatening diseases such as glaucoma and retinal disorders were found. Therefore, a regular eye examination is needed to detect the serious ocular diseases in the early stage.

This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

김재익,황국웅,정현욱,여창환 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.3

위성영상은 도시의 물리적 확산 및 변화를 예측하는데 많이 활용되고 있다. 그러나 이 방법은 도시화된 지역이 어느 정도의 강도로 개발되었는지를 파악할 수 있는 밀도분석에는 적절치 못하다. 이는 위성영상이 미시적 공간단위로 토지이용 현황을 분석하는 반면 통계자료는 거시적 공간단위로 구축되어 있어 통계자료를 미시적인 공간단위에 적용하는데 어려웠기 때문이다. 본 연구는 위성영상자료와 통계청의 기초단위구라는 미시적 구역통계자료를 활용하여 도시성장분석상 이들 자료를 통합하여 활용하는 것이 유용함을 입증하고자 하였다. 연구대상지역은 대구광역시로 하였으며, 분석자료로 1985년과 2000년의 위성영상 Landsat TM틀 와 구역통계자료로 기초단위구를 이용하였다. 분석결과 위성영상자료는 도시의 확산 그리고 기초단위구는 밀도 분석이 용이하여 도시성장에 따른 확산과 밀도변화를 동시에 파악할 수 있었다. Nowadays, a satellite image is widely utilized in identifying and predicting urban spatial growth. It provides essential informations on horizontal expansion of urbanized areas. However, its usefulness becomes very limited in analyzing density of urban development. On the contrary, zonal data, typically census data, provides various density information such as population, number of houses, floor information within a given zone. The problem of the zonal data in analyzing urban growth is that the size of the zone is too big. The minimum administration unit, Dong, is too big to match the satellite images. This study tries to derive synergy effects by matching the merits of the two information sources-- image data and zonal data. For this purpose, basic statistical unit (census block size) is utilized as a zonal unit. By comparing the image and zonal data of 1985 and 2000 of Daegu metropolitan area, this study concludes that urban growth pattern is better explained when the two types of data are properly used.

Objectives : This study was carried out to assess psychosocial distress of lead workers and to examine the relationship between lead exposure indices and psychosocial distress. Methods The study design was cross-sectional and research subjects were 234 lead workers in primary smelting industry. General characteristics, job characteristics and social support were obtained by self-administered questionnaire and history taking. Psychosocial distress was measured using PWI(Psychosocial Well-being Index), a 45-item self-administered instrument. Blood lead(PbB), zinc protoporphyrin(ZPP), δ-aminolevulinic acid in urine (ALAU) were selected as indicators of lead exposure. Results : There was significant difference in PWI according to lead exposure level and job characteristics. The results of correlation analysis showed that PWI was significantly correlated with PbB (r=0.203, p=0.002). Conclusions : Our results supported the association between lead exposure and psy-chosocial distress. The inclusion of psychosoclal distress measurement as a special health examination for lead workers was highly recommended for the effective health manage-ment.

The objective of this research is to analyze the comprehensive factors of competitive ability In national team taekwondo athletes. In order to achieve this objective, a case study was effected using 3 male and 3 female national team athletes, and 3 male and 2 female national team coaches Data was collected through In-depth interviews and perusal of relevant literature. Data was treated using an Inductive method of analysis, and the study's reliability, relevance, and ethical soundness were sufficiently demonstrated. Factors affecting the competitive ability of national team taekwondo athletes were divided into coaching factors, athlete factors, and environmental factors A synopsis of the analysis and conclusions of this study are as follows: First, aspects of coaching factors which influence athlete's competitive ability are the personality of the coach and his/her level of specialized knowledge as well as personal development and physical maintenance. It was found that the coach's character and personality are important factor's In training athletes Toward that end, the coach must have passion and demonstrate exemplary, responsible behavior. Coaches must possess specialized knowledge related to the enhancement of athlete's competitive ability. Scientific training can be carried out based on such specialized knowledge, Scientific training refers to systematic training and management which has been tailored to meet the personal needs of each athlete. In order to effectively train athletes, the coach must continuously improve him or herself and maintain good personal fitness. The coach must always be cognizant of changes in competition rules and international sport practices. Further, they must make unceasing efforts to further their own knowledge. Second, aspects of athlete factors influencing competitive ability include physical, technical, psychological, and personal maintenance considerations. Physical factors are proper body type and necessary physical fitness. When considering body type, just being tall or having long legs are not the entire picture, having well-balanced and proportional physical characteristics are most beneficial for the athlete. Regarding the athlete's physical fitness, the most important factors are muscular endurance, quick reaction time, and agility. Technical factors include basic technique and match control ability, Most importantly, teakwondo athletes must have must have mastered all basic techniques and have solid match management abilities developed through experience. Psychological factors include concentration, the desire to win, the necessary mind-set, and media appeal. Elite athletes like national team members must give as much weight to psychological factors which enhance competitive ability as they do to any other factors. Mental spirit or desire to win manifest themselves during training or competition as high levels of concentration and result in the athlete being able to perform at the highest level. Personal maintenance includes such factors as personal training and weight control and signifies the ability by the athlete to control all aspect of their lives that impact on competitive ability. National team level elite athletes all have, to some degree, good personal management habits whether it be weight control or conditioning all have their own ways of coping with pre-match nervousness and tension. In addition, they have their own methods of reducing stress accrued during training. Third, environmental factors which influence competitive ability in national team athletes include training facility atmosphere, refereeing, facilities and support. The training facility atmosphere should be such that athletes can train anytime they choose.In order to facilitate this, personal relations between teammates and junior-senior relations must be harmonious. Relations between athletes, between athletes and coaches, and between coaches themselves must be based on mutual trust and reliability. In other words, when the training atmosphere is supported by a foundation of mutual trust, training effectiveness can be maximized. During a match, the referee exerts a great deal of influence on the flow of that match Therefore, It is of utmost importance that the referee render impartial judgements in all cases. In order to improve competitive ability, important factors other that the effort of athletes and coaches include the active support of parents Also, other support in the form of facilities and training must be effected the support of the national federation In the process of training, steady communication between athletes and coaching staff regarding even the trivialities of everyday life and training is an important factor In improving competitive ability The trust required for this king of communication is formed the everyday actions of the coach which prove him or her to be one of exemplary character, reliable in word and action and fair in all matters large and small.

Background and Objectives: Benign tumors of the nose and paranasal sinues are rare in comparison with malignant growths. Authors aimed to investigate the incidence and characteristics of benign sino-nasal tumors. Materials and Methods: From 1994 through 2004, 25 cases of benign sino-nasal tumors (17 men and 8 women) were diagnosed and cared at the Department of Otorhinolaryngology-Head and Neck Surgery, College of Medicine, Konkuk University. We reviewed medical records of patients to find out clinical features, radiologic findings, operative findings, therapeutic options, and outcomes. Postoperative observation was given for fifteen months on the average. Results: The most common symptom was nasal obstruction, followed by nasal mass, frequent nasal bleeding, headache, and rhinorrhea, and the mass mainly placed in the lateral nasal wall. There were 12 cases (48%) of inverted papilloma, 4 (16%) cases of squamous papilloma, 4 (16%) cases of hemangioma, 1 (4%) case of pleomorphic adenoma, 1 (4%) case of leiomyoma, 1 (4%) case of lipoma. All the tumors were surgically removed. For the treatment of inverted papilloma, medial maxillectomy had been performed before 1997(2 cases); however, most cases have been managed with endonasal endoscopic technique since 1997. Recurrence was observed in two patients with inverted papilloma and one patients with squamous papilloma. Conclusion: Inverted papilloma is the most common benign tumor in the nose and paranasal sinuses, followed by squamous papilloma and hemangioma. The optimal management of benign tumors is complete excision of tumor and endonasal endoscopic surgery is an effective treatment for an inverted papilloma.

배 경 : ASO 검사는 S. pyogenes 감염과 류마티스열이나 급성 사구체신염 등 후유증을 진단하는데 매우 유용하다. ASO 정상치는 연령에 따라 달라지는 것으로 알려져 있으므로, 단회의 ASO 결과를 올바로 해석하기 위해서는 같은 지역의 동일한 연령의 정상치를 알고 있어야 한다. 방 법 : 저자들은 진주지역 학동기전 아동 (162명), 초등학생 (436명)과 성인 (231명) 세 군에서 ASO 정상치와 분포를 살펴보았다. 연쇄구균 감염 증상이나 징후가 없는 진주 지역 주민들을 대상으로 혈청내 ASO치를 자동화학분석기 (Cobas Mira, Roche)와 비탁기 (Behring Nephelometer 100 Analyzer)를 이용하여 정량 분석하였다. 결 과 : 학동기전 아동, 초등학생 및 성인에서의 평균 ASO치는 각각 71 IU/mL (표준편차 107), 285 IU/mL (표준편차 246) 및 80 IU/mL (표준편차 64) 이었고, 정상상한치는 각각 131 IU/mL, 433 IU/mL, 136 IU/mL 이었다. 결 론 : ASO 정상치 및 분포는 각 연령군에 따라 크게 다르므로, ASO 정상치는 연령에 따라 다르게 설정되어야 할 것이다. A군 연쇄구균 감염은 학동기전 아동이나 성인에서는 매우 드문 반면, 초등학생에서는 빈번함을 알 수 있었다. Background : Antistreptolysin O (ASO) is very useful as an indicator of recent streptococcal infection and its sequelae, such as rheumatic fever and acute glomerulonephritis. Becuase the upper limit of normal (ULN) value of ASO varies according to age, the ULN value of ASO in an area should be evaluated to accurately interpret single ASO levels of patients. Methods : The ULN value and distribution of ASO concentrations were investigated in three age groups of preschool children (N=162), elementary school children (N=436), and adults (N=231) in Chinju. ASO concentrations were measured quantitatively by autoanalyzer or nephelometer from sera of healthy population in Chinju who had no symptoms or signs of streptococcal infections. Results : The mean (±SD) ASO concentrations were 71 (±107) IU/mL, 285 (±246)IU/mL, and the UNL value of ASO concentratios were 131IU/mL, 433IU/mL, and 136 IU/mL in each group of preschool children, elementary school children, and adults, respectively. Conclusion : The distributio and ULN value of ASO concentrations varied according to age group. The ULN value of ASO concentrations should be set differently according to the patient's age. Group A streptococcal infections might be quite common in elementary school children, while very rare in preschool children or adults.
