N/A Background:Childhood atopic dermatitis(AD) has a profound effect on the quality of life, disturbing family and social relationships. Stressful familial condition from the child's AD may aggravate AD itself but no information concerning the effect of childhood AD on family function is available in Korea. Objectives:The aim of this study was to show how AD effects families, to identify the areas of life most affected and to evaluate the relationship between the effect and severity of AD. Method:The 10-questionnaire item(Dermatitis Family Impact questionnaire[DFI]) with assessment of severity of AD was studied in AD patients and compared with control subjects. Results:The average of the total score of the DFI questionnaire in the AD group was significantly higher than that of the control group (P<0.05) and was linearly related with AD severity, but not as highly (R2=0.161, P=0.003). The highest scoring question in the 10 questions of the DFI questionnaire was that of causing physical tiredness or mental exhaustion, and the lowest, that of time spent on shopping for the family. Conclusion:There is an obvious need to identify and to reduce the suffering of families of children with AD. The DFI may potentially be of value to help guide appropriate management of AD and as an added parameter in clinical trials concerning AD management. (Korean J Dermatol 2000;38(4):494~499)

The overpopulation in urban areas and the rapid increase in freight volume cause various social and environmental problems, and at the same time require more complex distribution networks and logistics facilities locating. In South Korea, demand for logistics facilities have also increased along with the explosive growth of the e-commerce industry since the mid-1990s, but there have not yet been many studies analyzing the demand so far, and in particular, only few studies focus on regional differences in demand for logistics facilities. Therefore, this study collected the national warehouse data registered until 2017, visualized the distribution pattern of the gross warehouse space, and investigated whether the warehouse demand really differs by region. As a result, warehouses were actually distributed differently by region and were concentrated in specific regions. Accordingly, this study explored socioeconomic, geographic, and industrial factors that explain the different warehouse demands for 225 administrative districts nationwide, measured the distance-based impact among 225 administrative districts, applied weights into the variables for regression analysis. The results showed that the coefficients and those signs are more statistically reliable in the model using the distance-based weights compared to the model with non-weighted variables, and 5 of the total 6 variables were found to be significant.

N/A Background: Cryosurgery uses freezing temperatures to achieve specific effects on tissues, and this method has been used to treat various skin diseases for the last five decades. The modern cryosurgery is especially effective on the treatment of benign, premalignant and malignant lesions including keloid, hypertrophic scar and pigmented disease such as Ota nevus. The results of cryosurgery depend on such factors as types of cryogen, freezing and thawing time, and numbers of the freezing-thawing cycle. Objective : The purpose of this study is to show differences among groups of disease, sites of treatment and applying methods through comparing freezing and thawing time. And specifying the optimum applying methods for the treatment of each specific disease is studied. Method: To attain the goal of the study, operation records of 224 patients, who received cryosurgical treatment at the Ewha Woman's University Dongdaemoon Hospital, have been analyzed. Results: 1. The numbers of male and female patients of selected group were 74 and 150, respectively, and their ages between 2 and 54 years. Among the group, 42 patients had epidermal pigmentary disease, 77 had dermal pigmentary disease and 105 had scars. 2. Ratios of TT (thawing time) to FT (freezing time) were significantly different among groups of disease (p<0.05). 3. Ratios of TT to FT were significantly different among groups of treatment site (p<0.05). 4. Ratios of TT to FT showed great difference between the group of rolling method applied and one of pressure method applied (p<0.05). Conclusion. The output of this study indicates that the result of the cryosurgery tends to be heavily influenced by the surgical method that is employed. It also proves that the pressure method tends to inflict more severe cryoinjury on the tissues than the rolling method. Each different tissue (Korean J Dermatol 2001;39 (7) 768-774) shows different sensitivity to the cold injury, and the longer the thawing time is, the more cryoinjury of tissues occurs. Therefore, to achieve the maximum therapeutic result while minimizing the undesired effect, adequate surgical method should be selected and applied to each specific disease. This concept is introduced in this study as Theory of Selective Cryolysis .

We experienced three cases of arteriovenous hemangioma in middle-aged patients. Each of them an asymptomatic small red to purple papule on the face and arm, which showed typical microscopic features of proliferating variously sized vessels in the dermis. An interesting finding was the increased number of mast cells identified in the stroma and perivascular channels, which may be associated with angiogenesis in inflammatory and neoplastic processes. Although arteriovenous hemangioma has been reported infrequently, its true incidence is considered to be higher than expected. Thus biopsy should be performed for exact diagnosis of small vascular lesions. (Korean J Dermatol 2000;38(4):506~511)

물류창고 Stock 공급 결정요인 분석 -온라인 쇼핑을 중심으로-

1970년대 이후 점진적으로 늘어나던 국내 물류창고의 면적 및 수량은 1990년대 중반 이후 급격하게 증가하였다. 특히 경기도를 포함한 수도권 지역의 증가추세는 가히 폭발적이라 할 만하다. 그러나 물류창고의 증가추세가 뚜렷한 현상임에도 불구하고 이러한 현상 및 수요의 원인을 분석하는 학술연구는 미흡한 상황이다. 본 연구는 건축물대장 자료를 전수 조사하여 1971년 이후 국내물류창고 공급 및 멸실 현황을 기반으로 국내 물류창고의 총 재고면적(stock)의 변화를 분석하고 공급의 결정요인을 분석하였다. 기존 연구에서는 다루지 않았던 온라인쇼핑 거래액의 영향을 분석하기 위하여 온라인 쇼핑이 활성화된 2001년 이후의 사회 경제적 변수들을 조사하여 다중회귀모형을 정립하였다. 분석을 위하여 2001년 1분기부터 2017년 4분기까지 17년간의 제조업 국내총생산, 지가지수, 금리(회사채 3년), 경제활동인구, 수입금액, 판매시설 및 온라인쇼핑 거래금액 등이 주요 독립변수로 선택되었다. 분석 결과, 물류부동산 면적규모 10,000㎡ 이상의 모형이 다른 모형에 비해서 모든 변수가 유의미한 영향력을 미치는 것으로 나타났으며, 특히, 온라인쇼핑 거래금액은 10분기의 시차를 두고 가장 큰 영향을 미치는 것으로 확인되었다. 본 연구는 시장 현황과 유기적으로 작용하여 변화하는 물류창고 수요의 새로운 영향 요인을 제시함으로써 물류창고에 대한 공급 정책 및 투자에 대한 새로운 판단기준을 제공할 것으로 기대된다. The total areas and the number of warehouses in Korea have gradually increased since the 1970s and rapidly grown since the mid-1990s. Especially the area of warehouses in metropolitan regions, Gyeonggi-do area, has explosively increased. Despite the distinct increasing trend, insufficient academic research has been conducted. This research analyzed full building register data to identify the supply and loss of Korean warehouses since 1971. And we analyzed factors affecting the warehouse stock based on the rapid changes in the Korean economic environment. This research investigated the market environment from different angles, focusing on the growth of online shopping market, which has not been considered thoroughly in preceding studies. An econometric model is proposed with various explanatory variables including the GDP of the manufacturing industry, land values index, interest rate (3-year corporate bonds), economically active population, the amount of income, the business volume of sales facilities and online shopping revenue for 17 years from Q1 2001 to Q4 2017. As a result, it was revealed that the model of logistics property larger than 10,000㎡ showed that all proposed explanatory variables had significant effects compared to other models. In particular, the transaction amount of online shopping showed the most significant effect with the time difference of 10 quarters. This is considered due to the increase in demand for warehouses that attracts capital gain. This research showed a new standard for determining supply policy and investment in warehouses considering the market trend.

Tufted angioma is a benign, slowly progressive angioma with typical histologic findings of small, circumscribed angiomatous tufts and lobules scattered in the dermis. More than 50% of cases occur during the first year of life, but rarely it develops late in life. There was only one reported case of tufted angioma after trauma in the English literature. We report a case of tufted angioma, which developed after electrocautery in a 61-year-old woman showing histologic features of typical tufted angioma.

Membranous lipodystrophy represent a distinct form of pathology in adipose tissue. Although first described as the rare neurologic disorder, a change has also been observed in a variety of inflammatory and noninflammatory dermatoses. It is characterized by the presence of cysts lined by amorphous eosinophilic material with a crenelated arabesque appearance. We report a case of deep fungal infection by Sporothrix schenkii with marked lipomembranous changes in the subcutaneous adipose tissue.

Sinusoidal hemangioma is a rare variant of cavernous hemangioma. Clinically, it develops in adults and predominantly in females, and presents as a solitary painless subcutaneous nodule. Histological finding of the sinusoidal hemangioma shows a well-circumscribed lobular architecture in the subcutaneous tissue. The lobulated mass is composed of dilated sinusoidal thin-walled vascular channels, which have a pseudopapillary pattern and back-to-back arrangement without much intervening stroma. We report a case of sinusoidal hemangioma which can be differentiated from the other vascular tumors and has never been reported in Korea.

Lanolin is a complex material consisting of a mixture of numerous esters and polyesters of high-moleculer-weight alcohols and fatty acids, Lanolin allergy is important because lanolin is widely used as an emulsifier in topical medicaments and in numerous cosmetic preparations. We report a case of allergic contact dermatitis in a 27-year-old female. An erythematous pruritic rash develgood around the eyelid developed after applying a new eye cream and was aggravated after applying Cambison ophthalmic ointment. Patch testing showed positive reactions to Cambison ophthalmic ointment, 30% wool alcohol, Amerchol L101 and Nivea cream. A use test with 100% Cambison ophthalmic ointment base was positive.
