Background: Solar urticaria (SU) is an uncommon type of photodermatoses characterized by erythematous wheal with pruritus after sunlight exposure, which shows a female predominance. Only a few studies to analyze the clinical features of SU were reported in Asia. Objectives: We aimed to analyze the clinical and photobiological characteristics of SU in Korea. Methods: We retrospectively investigated the medical records of patients with SU who visited the department of dermatology, Konkuk university medical center from January 2005 to January 2020. Results: Of a total of 44 patients, 36 (81.8%) were male and 8 (18.2%) were female. The mean age at onset was 17.6 years (range, 5-47) and the mean threshold time was 19.7 minutes. Among 32 patients who underwent phototesting, the action spectrum most commonly implicated was ultraviolet (UV) A only in 12 (37.5%), and then visible light (415nm) only was responsible for SU in 8 (25.0%). Three patients (9.4%) were induced by both UVA and visible light (415nm). Even 4 patients (12.5%) were triggered by only natural sunlight. Serum immunoglobulin E levels were measured in 33 patients, and 17 (51.5%) showed values higher than normal. The treatment most widely used were oral antihistamine (43.2%), followed by phototherapy (13.6%). Conclusion: SU is a rare photodermatosis in Korea, which shows a male preponderance. In this study, UVA and visible light (415nm) were predominant action spectrum of SU.

양수진,최영,이형영 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.3

국문 초록 연구목적 : 도시 여고생을 대상으로 청소년의 식이 태도와 자아 정체감 및 자아 존중감 사이의 관계를 알아보고자 하였다. 방 법 : 편의 표집 방법으로 광주광역시 5개 여고를 선택하였고 총 436명을 대상으로 하여 사회인구학적 특성, 한국판 청소년용 식이 태도 검사(Eating Attitude Test for Korean Adolescents ; EAT-26KA), 한국형 자아-정체감 검사(Korean adolescent Ego-identity Scale ;KA-EIS)및 Rosenberg의 자아 존중감 척도(Self-Esteem Scale;SES)로 구성된 설문을 주고 그 결과를 분석하였다. 결 과 : EAT-26KA 저수에 의해 식이태도를 분류하면 이상 식이 태도군은 45명(10.3%), 정상 식이 태도군은 391명(89.7%)이었다. 신체질량질수(Body mass index ; BMI)에 의해 여학생을 체형별로 분류하면 과체중군(BMI>25)은 16명(3.7%), 정상 체중군(19≤BMI≤25)은 304명(69.7%), 저체증군(BMI<19)은 116명(26.6%)이었다. 이상 식이 태도군과 정상 식이 태도군에 비해 체중, 키, BMI가 컸으며 SES점수가 유의하게 낮았다. 이상 식이 태도군과 정상 식이 태도군 간의 KA-EIS의 총점에서는 유의한 차이가 없었으나 하위요인 중 자기 수용성은 이상 식이 태도군이 낮았다. 과체중군은 EAT-26KA 점수가 다른 두 군에 비해 유의하게 높았으며 저체중군의 키가 정상 체중군에 비해 유의하게 높았다. 세 체형군에 따른 KA-EIS, KA-EIS의 하의요인과 SES의 유의한 차이는 없었다. EAT-26KA와 정적 상관이 있는 인구학적 특징은 체중과 BMI였으며, 부적 상관이 있는 척도는 SES이었다. KA-EIS와 정적 상관이 있는 척도는 SES이었다. 결 론 : 이상 식이 태도를 보이는 청소년이 10.3%를 차지하고 있었으며 이들은 낮은 자아 존중감과 자기 수용성을 보였다. 과체중군의 여학생에서 식이 태도가 좋지 않았다. 따라서 건전한 식이 태도에 대한 교육과 자아 존중감과 자기 수용성등을 증진시킬 수 있는 프로그램이 청소년들의 건강한 식이 태도에 도움을 줄것으로 생각된다. Objectives : This study was aimed to evaluate the abnormalities in eating attitude and the correlations between ego-identity and self-esteem among the urban high school girls. Methods : Four hundred and thirth-six high school girls were investigated by using Eating Attitude Test for Korean Adolescent(EAT-26), Korean Adolescent Ego-26KA, the high risk group was identified. We compared weight, height, body mass index(BMI), KA-EIS and SES between the high risk group and the control group. According to BMI, we identified a underweight, normal weight, and overweight group among subjects, and then we compared weight, height, EAT-26KA, KA-EIS, and SES among the three groups. Results : By EAT-26KA scores, 10.3% of girls had abnormal eating attitude and were considered as the high risk group for eating disorder. By BMI, 3.7%(N-16) of girls was overweight (BMI>25), 69.7%(N=304) was normal weight, and 26.6%(N=116) was underweight(BMI<19). The high risk group showed lower SES scores and 'self receptiveness' of KA-EIS than the control group. The overweight group showed higher EAT-26KA scores than other two groups. There were no significant differences in SES and KA-EIS among the three groups. KA-EIS was positively related to SES, and EAT-26KA was negatively related to SES. Conclusion : The distribution rate of the high risk group for eating disorder is10.3%, and the high risk group has low self-esteem and is poor in self-receptiveness. The overweight group is more likely to have higher EAT-26KA scores than other two groups. Therefore, it is useful to educate adolescents for the healthy eating behaviors and to provide them with the programs which promote the self-esteem and self-receptiveness.

본 논문은 고압 커패시터의 고장분석과 신뢰성 예측 결과를 다루고 있다. 부품의 수명과 고장률을 예측하기 위해서 두 가지 방법으로 고장 모드와 고장 메커니즘을 연구하였다. 에폭시 수지로 성형된 고압 커패시터가 절연내압 시험 하에서 저항이 제로로 되는 고장에 대하여, 근본원인 고장분석 체계를 효과적으로 수립함으로써 고장 메커니즘의 원인을 분석하였다. 특히 세라믹-에폭시 계면에서의 절연파괴 고장 현상이 강조되었으며, 본 연구에서 얻어진 결과의 타당성은 마그네트론에 장착된 고압 커패시터의 열사이클 시험 수행에 의한 가속시험 결과로부터 입증되었다. 시험 결과들은 결함이 있는 로트를 신속히 규명하고 B10수명을 결정하는데 유용하게 사용할 수 있다. 또한, 유전체의 절연파괴에 대해서 부하-강도 간섭모델을 이용하여 고장률을 예측하였다. This paper presents a result of failure analysis and reliability evaluation for high voltage ceramic capacitors. The failure modes and failure mechanisms were studied in two ways in order to estimate component life and failure rate. The causes of failure mechanisms for zero resistance phenomena under withstanding voltage test in high voltage ceramic capacitors molded by epoxy resin were studied y establishing an effective root cause failure analysis. Particular emphasis was placed on breakdown phenomena at the ceramic-epoxy interface. The validity of the results in this study was confirmed by the results of accelerated testing. Thermal cycling test for high voltage ceramic capacitor mounted on a magnetron were implemented. Delamination between ceramic and epoxy, which might cause electrical short in underlying circuitry, can occur during curing or thermal cycle. The results can be conveniently used to quickly identify defective lots, determine B10 life estimation each lot at the level of inspection, and detect major changes in the vendors processes. Also, thd condition for dielectric breakdown was investigated for the estimation of failure rate with load-strength interference model.

유양욱,김명규,박동수,김창원,김진섭,이정희,손병기 경북대학교 센서기술연구소 1995 센서技術學術大會論文集 Vol.6 No.1

The 0.6 μm N/O/N triple layer, Si_(3)N_(4)(150 nm)/SiO_(2)(300 nm)/Si_(3)N_(4)(150 nm), was deposited on silicon substrate and the N/O/N thin film diaphragm was formed using anisotropic etching technique. The stress of the formed diaphragm was very small with temperature variations. Combining this diaphragm and the optical fiber, intensity-type pressure sensor was fabricated and its pressure characteristics were investigated. The relation between the optical output power, inversely proportional to the deflection of the diaphragm, and the applied pressure was almost linear in 0~77 torr range.

김영수,진유동,문양고 釜山大學校生産技術硏究所` 1998 生産技術硏究所論文集 Vol.54 No.-

염화물함유 콘크리트의 투수성과 철근부식에 미치는 영향을 규명하기 위해 염화물 함유량을 0, 0.3, 0.6㎏/㎥으로 변화시키고 W/C비를 0.4, 0.45, 0.5, 0.6으로 변화시킨 상태에서 투수계수, 철근 부식면적율, 압축강도, 슬럼프, S.E.M에 의한 미세구조를 보통 콘크리트, fly ash 혼입 콘크리트, AE 혼입 콘크리트와 비교하여 다음과 같은 결론을 얻었다. 1) 콘크리트 투수계수는 W/C비 또는 염화물 함유량이 클수록 증가하였다. W/C비 0.5까지는 투수계수의 증가폭이 크지 않으나 W/C비 0.65에서는 염화물 혼입 및 보통 콘크리트의 투수계수가 크게 증가하여 W/C비가 염화물 함유량 보다는 특수성에 더 큰 영향인자임을 알 수 있었다. 2) 철근부식 면적율은 투수계수와 마찬가지로 W/C비 또는 염화물 함유량이 클수록 증가하였다. W/C비 0.65에서 보통 콘크리트의 투수계수는 염화물 혼입시와 유사하나 철근부식 면적율은 현격히 작은 결과를 나타내 투수계수의 증가에 따라 철근부식 면적율이 반드시 비례하여 커지는 것은 아님을 알 수 있었다. 3) 플라이애쉬 및 AE감수제를 혼입하면 콘크리트 투수계수 및 철근부식 면적율이 크게 감소하여 밀실화 효과가 우수하였으며, 피복두께를 2㎝에서 3㎝로 증가 시키면 염화물 및 혼화재 혼입 유무에 관계없이 철근부식 면적율은 모두 감소하였다. The purpose of this paper is to investigate the coeffecient of permeability and the properties of corrosion of steel in concrete containing chloride. For this purpose, the experiments for the permeability and the rate of corrosion area by selecting factors and levels such as chloride content, W/C and admixture were executed. The major results are as follows. 1) The coefficient of permeability was increased with increasing chloride is higher than that of plain concrete. 3) The permeability and the rate of corrosion area in concrete containing fly ash and AE water reducer is lower than that of plain concrete and concrete containing chloride at the same W/C 4) The rate of corrosion area was decreased with increasing covering depth from 2㎝ to 3㎝.

Objectives : This study aimed to develop the Korean version of World Health Organization Disability Assessment Schedule II (WHODAS II-K) with community dwelling elderly population. Methods : The WHODAS II-K was administered to 1204 community residents aged 65 or over in two areas of Kwangju, South Korea, in 2001. For assessing 'health condition', data on physical illness, depression (Korean version of Geriatric Mental State Schedule B3), and cognitive dysfunction (Korean version of Mini-Mental State Examination) were collected. For evaluating 'contextual factors', informations on demographic charactehstics (age, gender, living area, marital state, and religiou), socio-economic status (education, type of accommodation, number of room, previous occupation, and current employment), and social network were obtained. Results : WHODAS II-K showed high levels of internal consistency, split-half reliability, and inter-rater and test-retest reliabilities. In the correlation analyses, scores on the WHODAS II-K were significantly correlated with the unfavorable conditions in the all variables on health condition and contextual factors. Partial correlations of scores on the WHODAS II-K with health condition were significant even after controlling for contextual factors. Conclusion : The WHODAS II-K is a reliable and valid instrument for assessing disability in elderly population since it reflects physical illness, depression, and cognitive impairment, which are common in elderly.
