This study conducted to evaluate the association of work posture with cervical spine abnormality toward 106 microwave-oven assemblers. A self-administered questionnaire was used to obtain a general characteristics and a work history of workers. The posture of neck and shoulder joint of workers were measured with video tape recording and the simple X-ray of cervical spine was checked-up to observe the X-ray abnormality including degenerative change, curvature abnormality, disc space narrowing or disc canal narrowing. The result were as follows. 1. The prevalence of degenerative change among cervicobrachial disorder workers was 44.3%(47 persons), curvature abnormality was 43.4%(46 persons), disc space narrowing was 21.7%(23 persons), and disc canal narrowing was 21.7%(23 persons). 2. The prevalence of degenerative change at cervical spine was increased with the degree of neck flexion(flexed versus neutral; odds ratio (OR)=2.7), the total work posture of neck(mild or severe awkward versus neutral; OR=1.2, 3.4). 3. The prevalence of degenerative change at cervical spine was increased with the degree of the right shoulder flexion, the heaviness of the materials carried by the right hand and the degree of awkwardness at the total work posture of right shoulder(p<0.05). 4. There was no evidence of association between curvature abnormality, disc space narrowing, disc canal narrowing and work posture. In conclusion the awkward work posture was related with degenerative change of cervical spine among microwave oven assembling workers and the further study in these field must be made to prove the association objectively.

Reconstruction of the auricle is one of the most fastidious fields in plastic and reconstructive facial surgery, because the ear is made up of complex cartilage framework arid its thin skin envelope. Insertion of carved rib cartilage is the most popular method for framework fabrication. But it has some disadvantages such as donor site morbidity, lesser flexibility of rib cartilage, difficulty in carving structure and distortion of cartilage after calving. Furthermore surgeon's talent and sufficient practice are necessary for a satisfactory result. So we introduced the concept of perichondral graft to improve the framework fabrication. In 1972 Skoog and associates reported that free perichondral grafts could be used to produce new cartilage. And several other reports supported the chondrogenesis of free perichondral graft. We molded the human ear using silicone rubbed impression material. And the eat mold was wrapped up in perichodrium of rabbit ear and placed in a subcutaneous pocket in formes of graft and flap. Six and eight weeks later, rabbits were sacrified and the newly formed cartilage framework was harvested. Grossly it showed the same appearance as the human eat and elastic property of normal cartilage. In histologic examination, it showed mature structure of normal cartilage; large lacunae containing spherical chondrocytes surrounded by well defined capsule.

Nuclear morphology and size are important in the diagnosis and classification of non-Hodgkin's lymphoma. The recognition of morphologic features of the lymphoma cells and their interpretation are somewhat subjective and often difficult. We apply the morphometric study in touch imprints from 22 cases of non-Hodgkin's lymphoma classified by Working formulation. Determination of the exact size of the tumor cells and substantial diagnostic value of this method compared with histology are proposed. Morphometric parameters, including nuclear area, perimeter, maximal diameter (D-max), diameter of an equivalent circle for a measured area (D-circle), circularity factor (From PE) and regularity factor (Form AR) are measured, using Kontron, user-controlled image analyser (IBAS-1). The correlation between morphometric and histologic diagnosis is relatively good, except for 2 cases of Burkitt's lymphoma, measured as large cell and 2 cases of large cell lymphoma measured as medium cell. The most reliable parameter of the nuclear size is D-circle. The parameters for the nuclear shape, Form PE and Form AR, also reflect the nuclear cleavage and polymorphous pattern. The large cell group shows more wide standard deviation than small and medium cell groups, reflecting heterogeneity and variability in unclear size of large cell group. We suggests the morphometric analysis using touch imprints is complementary diagnostic tool for more accurate and reproducible diagnosis.

PURPOSE: This study was done to explore the relationship in hospital nurses' of communication competence, communication types, and organizational commitment and to provide basic data for developing programs to improve internal communication and to promote nurses' commitment to their organizations. METHODS: The participants included 316 nurses who worked in two general hospitals. The tools used for this study were the Global Interpersonal Communication Competence Scale (GICC) and Communication Satisfaction Questionnaire by Downs & Hazen (1981), revised by Seo (2002) and Mowday's tool (1979) for organizational commitment. Data were analyzed using SPSS/PC+12.0. RESULTS: The mean score for communication competence was 3.46, and for organizational commitment, 3.19. For communication types, the mean score for formal communication was 3.18 and informal communication, 2.59. Communication competence had a positive relationship with formal communication (r=.32) and with informal communication (r=.16). Organizational commitment had a positive relationship with formal communication (r=.53), communication competence (r=.30), and informal communication (r=.27). CONCLUSION: The results indicate the necessity of developing programs to promote nurses' communication competence and also developing a system that will enrich active communication. Systematic and continuous training in communication is also highly recommended.

Thirty three cases of metastatic ovarian carcinoma were analysed cilincopathologically. The patient's age ranged from 20 to 68 years, the average being 44.3. Most ovarian tumors were bilateral and asymmertically enlarged, firm and occsaionally multicystic. Histologic examination revealed adenocarcinoma in 31 cases, of which Krukenberg tumors in 14; squamous cell carcinoma in 2. The most common primary site was gasrtointestinal(75.8%), followed by genital, breast and gallbaldder. Most Krukenberg tumors were originated from poorly differentiated adenocarcinoma of stomach. The ovarian and primary carcinomas were synchronously diagnosed in 15 cases, while in 3 cases the primary carcinoma was not round until the ovarian tumor had been removed.

PURPOSE: This study was performed to identify skin health status and the factors influencing skin hydration in the institutionalized elderly. METHODS: The subjects were 139 elders living in 2 nursing homes in Seoul. Data for skin health status were collected by measurement of skin hydration, sebum, trans-epidermal water loss and pH using Corneometer, Sebumeter, Tewameter and Skin pH-meter on face, flank, arm and leg. Baseline data were collected by a structured questionnaire. The data were analyzed by SPSS/WIN 12.0 program. RESULTS: Skin hydration and pH were relatively low especially on arms and legs but sebum and TEWL were not low, relatively. There were significant differences in skin health status according to gender, smoking, alcohol intake, and bath cleanser. There was significant positive correlation between skin-hydration and bath-time, TEWL and bath-frequency. Smoking, bath-cleanser, bath-time. pH and gender were identified as the significant influencing factors of skin hydration. CONCLUSION: Smoking, bath-time and pH need to be considered as important control factors for increasing skin health status in the institutionalized elderly.

Primary malignant lymphoma of the appendix is an unconnnon neoplasm although the gastrointestinal tract is the most common extranodal site of malignant lymphoma. We report a case of primary malignant lymphoma of the appendix in a 54-year-old male, who presented with pain in the right lower abdomen. An appendectomy was performed. The appendix measured 9.5 cm in length and 5.5 cm in diameter. Cut sections showed a solitary circumferential mass in the appendiceal lumen. Light microscopic features were compatible with malignant lymphoma of diffuse large cell type(Working Formulation) and the immunophenotype was B cell type.

A Bednar tumor is a variant of dermatofibrosarcoma protuberans(DFSP). The clinical and histopathological findings of Bednar tumors are identical to DFSP except for the presence of melanin-containing cells scattered within the lesion, so called pigmented DFSP. The majority of Bednar tumors are seen as DFSP present as multinodular protuberant masses in the skin. They can also present as an atrophic depressed scar-like lesions without any nodularity. We report an uncommon clinical presented case of a Bednar tumor on the back in a 22-year-old female. She presented with an asymptomatic, firm, bluish, chestnut sized, depressed and atrophic lesion on the back which had been present for 6 years. A Histopathological examination revealed massive proliferation of spindle-shaped cells arranged in a tight storiform pattern mixed with scattered pigmented cells. On immunohistochemical staining, the tumor cells were positive for vimentin, a -l-antitrypsin, and CD34, but were negative for cytokeratin, neurofilament, and factor XIIIa. The majority of the tumor cells was negative and the pigment cells were positive for the S-100 protein. The patient was treated by a wide local excision of the lesion. There has been no evidence of recurrence after 20 months post-operative follow up.
