The clinical and mycological investigation was made with 68 cases of tinea corporis who had visited the Dermatologic Clinic of N.M.C. from Nov. 1985 to Oct. 1988. The results were as follows : 1. The ratio of male to female was 1.1: 1, and tinea corporis was most preva lent in the twenties. 2. 25 cases (36.8%) had a history of contact with infected animals or soil. 3. 75% of cases had less than 2 lesions. The exposed area was more frequently affected, and the face being the most frequent site. 4, Concurrent infection of tinea corporis with other types of dermatophytosis were noted in 33 cases (48.8%), and the most common was tinea pedis. 5. From the 68 cases, 49 organisms composed of 4 species were isolated, which were T. rubrum (32 cases), M. Canis (11 cases), T. mentagrophytes (5 cases) and M. gypseem (1 case). 6. Of the clinical variants of tinea corporis, the annular type was most comm only noted. No species specificity was noted in annular type, but T. rubrum was the major causative organism of eczematous and plaque type, and M. canis was the only isolated organism in herpetiform type. 7. As compared with other dermatophytes, M. canis was more commonly isolated from the smaller lesion.

We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

3.The Relationship among Subjective Health Status, Wisdom, and Self-care Agency in Korean Older Adults.
Journal of Korean Academy of Community Health Nursing 2015;26(4):355-363
PURPOSE: This study identified the relationships among subjective health status, wisdom, and self-care agency of Korean older adults. METHODS: The participants were 274 older adults from Daegu, aged over 65 years. Data were collected by visiting two social welfare centers, two senior welfare centers, and nine senior centers in Daegu from January 18 to February 5, 2013. Data were analyzed through one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple linear regression using the IBM SPSS/WIN 19.0 statistical program. RESULTS: A significant positive correlation was found among older adults' subjective health status, wisdom, and self-care agency. Self-care agency was affected by wisdom (47%, beta=.55), the physical component summary (18%, beta=.31) and mental component summary (1%, beta=.12) of subjective health status, and the absence of disease (2%, beta=.13). CONCLUSION: This study suggests that nursing interventions to promote self-care agency in older adults should be developed based on the characteristics of their subjective health status and wisdom.

The malignant fibrous histiocytoma (MFH) was first introduced in 1963 to refer to a group of soft-issue tumors characterized by a storiform or cartwheel-ike growth pattern and predominantly fibroblastic appearance. It was postulated that they were derived from histiocytes that could assume the appearance and function of fibroblasts. MFH has been recognized to be the most common sarcoma in the soft tissue of late adult life which involves the deep fascia or skeletal muscles of the extremities or retroperitoneum. It has been noted in other organs, however, it rarely arises in the liver. We report two cases of primary malignant fibrous histiocytoma of the liver histopathologically confirmed after surgical resection-storiform pleomorphic and myxoid subtypes in the 55 year old male and 49 year old female patients, respectively, and describes the clinical courses, characteristics and pathologic aspects with review of the related literatures.

8.Socioeconomic factors related to tooth brushing behavior among adults in Korea: analysis with 2019 Community Health Survey data
Journal of Korean Academy of Oral Health 2022;46(2):47-55
Objectives:
This study aimed to identify the socioeconomic factors related to tooth brushing behavior among adults in Korea.
Methods:
This cross-sectional study used data from the Korea Community Health Survey (KCHS) in 2019. Respondents aged 19 years and older (n=299,099) comprised the study sample. The dependent variable was tooth brushing behavior, whereas the independent variables were demographic and socioeconomic factors. The data were processed using chi-squared test, independent t-test, ANOVA, and adjusted multiple logistic regression analysis were performed. Statistical analysis was performed using the STATA 17.0 program, with significance set at the 5% level.
Results:
About half (55%) of the respondents brushed their teeth at least twice a day. The findings also revealed significant differences according to socioeconomic status (P<.01). Those who brushed their teeth less than twice a day had the following characteristics: men, aged 45 years or older, low income, working outside, less educated, without a spouse, and living in rural areas. Adjusted multiple logistic regression analysis showed that the area of residence contributed to tooth brushing behavior.
Conclusions
The area of residence, as well as socioeconomic status, should be considered in oral health education and intervention strategies.

OBJECTIVE: The aim of this study was to evaluate the strain induced in the cortical bone surrounding an orthodontic microimplant during insertion. METHODS: A 3D finite element method was used to model the insertion of a microimplant (AbsoAnchor SH1312-7, Dentos Co., Daegu, Korea) into 1 mm thick cortical bone with a pre-drilled hole of 0.9 mm in diameter. A total of 1,800 analysis steps was used to simulate the 10 turns and 5 mm advancement of the microimplant. A series of remesh in the cortical bone was allowed to accommodate the change in the geometry accompanied by the implant insertion. RESULTS: Bone strains of well higher than 4,000 microstrain, the reported upper limit for normal bone remodeling, was observed in the bone along the whole length of the microimplant. At the bone in the vicinity of the screw tip, strains of higher than 100% was recorded. The insertion torque was calculated at approximately 1.2 Ncm which was slightly lower than those measured from the animal experiment using rabbit tibias. CONCLUSIONS: The insertion process of a microimplant was successfully simulated using the 3D finite element method which showed that bone strains from a microimplant insertion might have a negative impact on physiological remodeling of bone.

PURPOSE: E-cadherin(E-CD) is a family of Ca++-dependent intercellular adhesion molecules, plays essential roles in organogenesis and in the maintenance of normal structure and function. Decreased expression of E-CD correlates with tumor aggressiveness, advanced stage and metastasis. In renal cell carcinoma(RCC), however, this correlation is not well established and prevalence of negative expression of E-CD is higher than in other carcinomas. We focused our interest on E-CD expression in RCC and its clinicopathological implications. MATERIALS AND METHODS: Retrospectively, we reviewed 34 cases with RCC that were reclassified according to Mainz classification. Tumor stage, grade were determined according to the Robson method and Fuhrmann`s grading system. We detected E-CD expression in RCC by immunohistochemical staining and investigated the relationship between E-CD expression and clinicopathological features including prognosis. RESULTS: Thirty four cases of RCC were consisted of 21 cases(61%) of non-papillary clear cell type, 2 cases(6%) of chromophil type, 3 cases(9%) of spindle cell type and 8 cases(24%) of chromophobe type by Mainz classification. Especially, E-CD expression showed a strong positive reaction along the cell membranes in all 8 cases of chromophobe type. Our immunohistochemical study of E-CD expression in 34 RCC specimens showed 73% of positive expression and 27% of negative expression. Absence of E-CD expression was correlated with the high tumor stage and grade( stage & grade 3 or 4. p<0.05 in chi-squar test). All of metastatic cases showed a negative expression of E-CD. CONCLUSIONS: The differential expression of E-cadherin in renal cell carcinomas suggest that the tumor cell origin and differentiation. Especially, chromophobe cell type may have different biologic characteristics from other types of renal cell carcinoma. In this study, E-CD expression was seemed to be lost in RCC with a high stage and grade. In addition, preserved E-CD expression was associated with better prognosis than reduced E-CD expression.
