The purpose of this study was to develop a program for improving peer relations of preschoolers and to investigate its effectiveness, which was held in the natural setting of a classroom. The contents are consisted of understanding emotion, controlling negative emotion, and improving self-esteem, communication skills, and prosocial behaviors. The participants for the study were 105 4-year-o1d preschoolers who were divided into two groups such as experimental and control groups. Among them, 57 children were assigned for the experimental group, and 48 children for the control group. The experimental group participated in the program for 40-50 minutes per day once a week for 12 weeks during both the spring and fall semesters, while the control group received no treatment. As compared to the control group, children in the experimental group showed a significant increase in peer acceptance after they participated in the program, especially for both semesters.

본 논문에서는 자율 이동 로봇의 학습을 위해 신경망과 진화 알고리즘을 이용한 방법을 제안한다. 이것은 자연계의 생물이 진화와 학습을 통해 환경에 적응해 나가는 방식과 유사하다. 또한 본 논문에서는 행동기반 제어 방법인 포섭구조를 이용해 로봇의 행동을 제어하는 방법을 제안한다. 포섭구조는 행동규칙을 병렬적으로 모듈화 하여 낮은 레벨에서는 기본적인 행동을 담당하고, 높은 레벨에서는 좀 더 복잡한 행동을 담당하는 구조로 되어있다. 따라서 각 행동 레벨이 협조를 함으로써 복잡한 임무를 수행할 수 있다. 포섭구조에서 각 레벨의 제어기는 신경망으로 규정하며 각 행동 레벨이 서로 영향을 주고받으며 진화함으로써 주어진 임무를 달성하도록 한다. 제안된 방법은 자율 이동 로봇인 Khepera 로봇을 이용해 실제 환경에서 구현함으로서 그 유효성을 입증한다.
單純回歸模型에서 相關係數에 관한 考察과 假說檢定에 대하여

In order to estimate and test the population correlation coefficient p, the distribution of the sample correlation coefficient r derived from the sample should be understood. This thesis discusses the p. d. f. f(r) of the sample correlation coefficient r obtained from the bivariate normal distribution under two different cases. One is that the population correlation coefficient p is zero and the other is that nonzero. Finally, the tests of statistical hypothesis have been done saparately.

Reactions to a bee sting ranges from mild erythema to severe anaphylactic reactions. Occasionally, a sting may be retained in the skin and a foreign body reaction to the sting may persist. In traditional Korean medicine, bee sting therapy applies a bee sting directly into a lesion to treat various diseases. Although, some cases about foreign body reaction induced by bee sting were reported, there is no report showing bee sting in biopsy specimens. A 50-year-old woman presented mild pruritic grouped papules on both lip angles for 7 months. She had suffered from recurrent herpes simplex. As a treatment, multiple bee stings had been applied on the the skin lesions several months before. Interestingly, we found apparatuses suspected to be retained stings of bees, which were showed as yellow sticks with central cavity filled with eosinophilic venom in the biopsy specimen. The retained apparatuses were surrounded by hair follicle-like structure and a granulomatous inflammatory cell infiltrate. In H&E staining, that apparatuses were consistent with bee stings. Cutaneous reactions induced by long-standing retention of bee stings in the tissues may cause some difficulties in diagnosis, because of nonspecific, neoplasm-like changes in clinical and histopathological examination. Herein, we report an interesting case of a foreign body reaction induced by retained bee stings, demonstrated in comparison with live bee stings.

Background: Trichophyton (T.) mentagrophytes is the second common dermatophyte in Korea. But there were rare reports on epidemiological and mycological analysis of T. mentagrophytes with long term and large scale study in Korea. Objectives: The aim of this study is to explain epidemiological and mycological characteristics of T. mentagrophytes in Korea. Methods: During the 21-year-period from 1992 to 2012, 6,250 patients with T. mentagrophytes were surveyed with respect to annual incidence, the distribution of the subjects according to age, sex, season, involved sites and a place of residence. Patients with T. mentagrophytes infection were clarified with fungal culture. In addition, we classified the colony appearance of T. mentagrophytes into granular, persicolor, powdery and downy colony. Results: In an epidemiological analysis, annual incidence reached its peak in 2005, and then gradually decreased. T. mentagrophytes was most common in July at monthly distribution. It was also found predominantly in middle-aged adults, especially in forties in age. In a mycological analysis, powdery colony was most common, followed by persicolor and granular colony. Clinically, tinea pedis was the most common T. mentagrophytes infection, followed by tinea unguium and tinea facieii. Conclusion: This massive, long term study on T. mentagrophytes infection leads us into epidemiological and mycological information in Korea.
FCP 6 : Sentinel lymph node biopsy of the 104 malignant melanoma of KNUH over 9 years (2006~2014)

Background: In these days, Sentinel lymph node biopsy (SLNB) is used as the most sensitive and specific staging tool available for determination of disease status of regional lymph node and it also developed as a technique to surgically assess the regional lymph nodes i.e. sentinel lymph node(SLN) and allowed to spare node-negative patients unnecessary and potentially morbid complete lymphadenectomies. Objectives: To examine the clinical analysis of SLNB cases in Kyungpook national university hospital (KNUH) over 9 years. Methods: In the period from January 2006 to January 2014, a SLNB was performed in 104 patients under cooperation of the department of dermatology, general surgery or orthopedic surgery in KNUH. Data were collected from medical records and the melanoma registry of KNUH. Results: Of the 104 melanoma patients who underwent SLNB, 49 were males (47.1%), 55 were females (52.9%) and their ages ranged from 34~93 years (average: 60.9). Detection rate of SLN was 98.1% (102/104). Twenty nine patients had a tumor-positive SLNB (27.8%) and underwent completion regional lymph node dissection. The mean Breslow thickness of the primary tumors was 3.76 mm, and the proportion of ulcerated melanomas was 51.4%. Two side effects had been observed such as seroma (1case) and lymphocele (1case). Conclusion: Herein, we reviewed the importance of SLNB as prognostic and staging tools with minimal morbidity through our experience of 104 malignant melanoma cases during past 9 years.
