Lentigo maligna(LM) is a pigmented lesion that occurs on the sun-exposed skin of an older patients and may become lentigo maligna melanoma(LMM). Currently the percentage of LM type melanoma appears to be increasing, and this rise has been attributed to increasing UV radiation exposure. In addition to UV radiation, estrogen and progesterone, and nonpermanent hair dyes have been proposed as risk factors. A case is a 66-year-old female with a 3 years history of pigmented patch. She had a gradually enlarging irregular bordered brown to black mottled patch on the right temple area. Histologic examination revealed atypical melanocytes along the basal layer of atrophic epidermis, arranged in solitary units and small nests. Perilesional skin showed many scattered melanophages and regressing nevus cell nests which suggested preexisting nevus underwent regressive change. On the basis of clinicopathologic examination we diagnosed this case as lenigo maligna arising from nevocytic nevus and then we removed the lesion by wide surgical excision and could not find any recurrence until now.

Pemphigus foliaceus is a rare, relatively mild and chronic variety of pemphigus which is characterized by superficial flaccid bullae which show acantholytic changes in the upper part of the epidermis histopathologically. Present case is a 40-year-old female with a 2 month history of yellowish colored verrucous plaques on the whole scalp. 6 years ago, she had been admitted to our hospital because of nearly generalized erythematous eroded patches, crusted plaques and bullae and diagnosed as pemphigus foliaceus and treated with corticosteroid and methotrexate. 2 months ago, an additional lesion was found on the scalp, where yellowish colored, verrucous surfaced plaques were observed. Histologic examination on the verrucous plaque showed hyperkeratosis, acanthosis and papillomatosis with acantholysis in the granular layer, leading to a subcomeal blister and dyskeratotic granular keratinocytes were seen within the blister. On the basis of clinicopathologic examination we diagnosed as pemphigus foliaceus and then we treated her with prednisolone and the skin lesion had subsided 7 months later. We report a patient of pemphigus foliaceus who was presented with verrucous surfaced plaque, which clinically mimicked pemphigus vegetans.

본 연구는 한국 대학의 교양교육 서비스와 만족도에 관한 연구이다. 연구 분석 결과 학생들은 교수들의 공감성 및 신뢰성 그리고 모든 서비스 품질요인들에 만족을 하고 공부하고 싶은 과목과 학점취득이 쉬운 과목에 만족도가 높은 것으로 나타났다. 그러나 공부의 양과 수강생수의 규모 등 수업의 내용과 질에 영향을 줄 수 있는 교육 요인들은 만족도에 전혀 영향을 주고 있지 않다. 학생들은 좋아하는 과목을 교수들이 쉽고 편하게 자상하게 해주면서 학점을 잘 주면 만족도가 높아지는 것으로 나타났다. This study investigated the relation between the liberal arts education service and students' satisfaction. The results of the study show that students are satisfied with all of five service quality factors, students' intention of studying, full time instructors' teaching and high GPA in taking liberal arts classes. However, educational factors such as the quantity of home work, frequency of test and the size of class, which can influence the quality and contents of classes, do not impact the students' satisfaction of liberal arts education. The college students of Korea may tend to be more satisfied with the liberal arts classes which they feel easier to study and to get better grades.

This study was conducted to identify which service quality factors influence customers’satisfaction and revisiting of the fast food shops in Korea. The result of this study shows that food quality is the most important factor for the fast food shop customers’satisfaction and revisiting intention.Food service industry has been dramatically increased for last ten years in Korea because of increasing income and the number of working women. Nowadays foreign style restaurants have been more popular than traditional Korean restaurants to Korean young people. Among foreign style restaurants, fast food shop has been grown for last ten years. Fast food industry belongs to service industry and service quality is very important to operate fast food shop. It is necessary that fast food shops improve service quality to get competitive advantages. Before improving service quality, it is very important to identify critical service quality factors influencing customers’satisfaction and intention of revisiting. Thus, this study conducted an empirical study to provide strategic suggestions for improving fast food shop customers’satisfaction and intention of revisiting.Based on the review of related literature, six service quality factors including PZB (1988)’s five service quality dimensions were selected in this study. They are tangibility, reliability, responsiveness, assurance, empathy and quality of foods. Among six service quality dimensions, tangibility was redefined as quality of shop and quality of foods because tangibility includes foods and all equipments, facilities of shop and everything of shop building. Thus, among six quality factors, quality of foods and quality of shop were used to measure tangible service quality factor. Reliability, responsiveness, assurance and empathy were utilized as the observational variables for intangible service quality factor. And it is necessary to develop items to measure the quality of foods. Five variables of taste, fresh materials, sanitation, shape, temperature were employed to measure the quality of foods. And then we designed a causal model to find out the service quality factors influencing customers’satisfaction and intention of revisiting in Korean KFC shops.According to the purpose of this study, we collected data from respondents who visited KFC shops in Seoul, Korea. Four KFC branches respectively at Kangnam and Incheon Airport, Seoul National University, Donamdong were selected for data collection respectively. Data collection process was conducted in February, 2002. We collected total 489 questionnaires from people visiting four KFC shops selected for collecting data in Seoul, Korea.After collecting data, the dimensionality of the six service quality factors were examined by means of a confirmatory factor analysis. Although Chi square is significant, GFI, AGFI, and RMR appear good. Thus, the result of CFA suggests that six quality dimensions were confirmed. And then a structural equations model analysis was conducted to identify which factors among six service quality factors influence customers’satisfaction and repurchase intention of the fast food franchisees in Korea. Although Chi square is significant, the values of GFI, AGFI, and RMR are appropriate. Thus, the fitness of model is fine. The results of the causal analysis show that food quality is the most important factor for the fast food shop customers’satisfaction and shop quality also influences customers’satisfaction. But they don’t influence the repurchase intention of the customers. In addition customers’satisfaction impacts the repurchase intention of customers. However, intangible service quality does not influence customers’satisfaction. The results of this study give a very important suggestion that geographical location and building values of shop, which are very expensive to maintain in Korea, do influence customers’satisfaction. And the taste of food is found as the most critical service quality factor for Korean fas

Sebaceous carcinoma is a malignant tumor derived from the adnexal epithelium of sebaceous glands and is usually located on the meibomian glands of the eyelid, but may occur on the extraocular sites. We present two cases of sebaceous carcinoma developed on the unusual site. The first case was 66-year old woman, who had 2.2×3.0cm sized, yellowish, verrucous surfaced plaque on the abdomen for 20 years. The second case of 79-year old man had annular shaped erythematous greasy patch with peripherally located flat plaque on the left scapular area for 1 month. His past medical history included subtotal gastrectomy for early gastric cancer(type II a) and could not find any recurrence or metastasis for 4 years duration. The histopathologic examination revealed irregular, variable sized tumor lobules. Each lobule was composed of sebaceous and undifferentiated cells showing considerable variation in the shape and size of their nuclei and prominent nucleoli. On the basis of clinicopathologic examination we diagnosed first case as sebaceous carcinoma and second case as Muir-Torre syndrome.

본 연구의 분석 결과 법률 서비스를 경험한 집단과 경험하지 않은 집단 모두 변호사 사무실 서비스에 대한 기대치는 높으나 두 집단 모두 변호사 사무실 서비스는 낮은 것이라고 경험 또는 예상하고 있다. 이는 한국의 변호사 업무의 과독점성으로 인하여 서비스 품질 수준이 낮아 왔다는 것을 반영하는 것 같다. 법률서비스 고객들은 고객들의 편에 서서 자상하게 이해 해주면서 법률서비스를 수행하면 만족이 높은 것으로 나타났다. 또한 변호사 사무실의 유형적인 요소인 근로자의 단정함과 교통이 편리한 위치등도 고객만족에 영향을 주는 것으로 분석결과는 보여주고 있다. This study is the first research for the lawyers' office service quality in Korea. Several T-tests' results show that the performance of lawyers office service was perceived much lower than the expectation of customers. A causal analysis was conducted to identify which service quality factors influence customers' satisfaction of the lawyer's office in Korea. The results of the analysis show that tangible and empathy service quality factors are the most important factors for the lawyers' customers' satisfaction. Thus, lawyers' office should invest some money in selecting location and building including interiors to increase customers' satisfaction in Korea. And then, lawyers should improve the empathy quality factor which make their customers feel their law office comfortable and helpful to them.
