우리나라에서 현재 적용중인 배전용 지중케이블은 1973년 처음 도입되어 도시의 중심 번화가와 변전소 인출개소 및 신도시 택지개발 지역 둥에 주로 설치되어 현재는 약 17,231 C-km (2002.12말 기준)에 이르고 있다. '86 아시안 게임과 '88 서울올림픽을 대비해 설치했던 케이블들은 설치 당시의 열악한 제작, 시공 및 관리 기술의 부족으로 많은 문제점을 가지고 있다. 이런 불량케이블이나 20년 이상된 노후케이블의 절연상태를 파악하기 위해 현재 적용 기준으로 되어있는 등온완화전류법을 이용한 열화진단장비를 현장에 적용해 보고 사례를 분석해보므로써 이 장비의 문제점과 향후 개선방향을 모색해 보았다.

Pneumoparotid is a rare diagnosis to consider when faced with unexplained parotid swelling. It is caused by an excessive increase of intraoral pressure and reflux of air through the Stensen duct and its glandular branches. It is more likely to occur in persons who have regularly raised intraoral pressure, for example glass and balloon blowers and wind instrument players. It can also be self-induced by habitual tic. Herein, we report a rare case of pneumoparotid with initial presentation of painless swelling in left parotid region. It was caused by habitual cheek inflating and improved with conservative management.

Objectives: The aim of this study was to analyze the reliability of the Korean language version of the Research Diagnostic Criteria for Temporomandibular Disorders(RDC/TMD) axis II questionnaire among TMD patients. Methods: The Korean version of the RDC/TMD questionnaire was distributed to 154 TMD patients(31 men, 123 women) who visited Seoul National University Dental Hospital. The test-retest reliability was also assessed among the same subjects with a one- or two-week time interval. The subjects did not receive any form of therapy until the retest administration was completed. Results: The internal consistency reliability of pain intensity, disability score, jaw disability, and psychosocial status were 0.92, 0.94, 0.68, and 0.94, respectively using the Cronbach's alpha coefficient of the 1st test. Test-retest reliability coefficients of each items of the questionnaire ranged from 0.40 to 0.94 assessed with kappa value, and the intra-class correlation coefficient(ICC) for each subscale ranged from 0.81 to 0.93. Test-retest reliability coefficient of the graded chronic pain(GCP) scale was 0.63. Conclusions: The Korean language version of RDC/TMD axis II questionnaire demonstrated good reliability. It can be used as a valuable instrument for the analyses of the psychosocial aspects of the TMD patients in Korea.

The value of exfoliative sputum cytology in diagnosis of lung cancer has been accepted with bronchoscopic technique and results has been much improved by foreign investigators, but there was not presented accurate reports for sputum cytologic evaluation in Korea. We tried to find indicators of cytologic tests result in our hospital. During the period between May, 1980 and August, 1982, 400 patients, tested at Department of Thoracic and Cardiovascular Surgery of Kosin Medical College, had diagnostic bronchofiberscopic examination, and the cytologic study of sputum and bronchial secretions were performed. The sputum or bronchial secretion during bronchofiberscopic examination were obtained with various methods and the name of specimen were labeled as I, ASPIRATION SPUTUM, which was collected initially endobronchial sputum as introducing of scope, II, WASHING SPUTUM, which was collected washing bronchial secretion, III, BRUSHING SPUTUM, which was washing solution of brushing instrument and endobronchial sputum after brushing of lesions, IV, POST-SCOPIC SPUTUM, which was expectorated sputum as soon as removing of scopic instrument, V, ALL SPUTUM CYTOLOGY & CELL BLOCK, which was collected all specimen of above procedures. The diagnostic results of bronchofiberscopic examination was disclosed 174 cases [43.5%] of proved lung cancer, 47 cases [11.8%] of suspected lung cancer in grossly, and 179 cases [44.8%] of others finding except cancer. Patient with bronchofiberscopically grossly evidence of lung cancer which were not confirmed histologically or cytologically were excluded from this cytologic study. Histologic and cytologic correlation in proven lung cancer, 174 cases was revealed that number of cytologic positive patients were 45 cases [38.7%] among the 117 cases of proved squamous cell carcinoma, 12 cases [38.7%] among hislogically unknown cancer 34 cases and 6 cases [33.3%] among small cell undifferentiated carcinoma 18 Gases. Total cytologic positive result was presented as 67 cases [38.3%]. The other type of lung cancer, histologically, could not comparison because of small cases. The sequence of positive cytologic result in I-V specimen were disclosed as II, WASHING SPUTUM 57.6%, and V, ALL SPUTUM & CELL BLOCK 41.4%. The I, III & IV result were 28.6%, 22.2% and 26.1% respectively.

This study aims at developing Reminiscence Function Scale-Short Form(RFS-S) and verifying it as a supplemental diagnosis instrument to judge differences between normal and mild cognitive impairment and useful measure to rate effects of reminiscence therapy in the clinical field through internal consistency reliability and criterion validity. The study also aims at figuring out factors affection reminiscence function by figuring out demographic features of RFS-S. The research subjects were the control group of 60 normal people and experimental group of 58 people with mild cognitive impairment and both groups were over 65 years old. For internal consistency reliability(Cronbach's alpha) between questions was reliable with 0.63. Convergent validities of RFS-S with SRT and CDR-SB were 0.20(p<.05) and -0.25(p<.001), respectively, as both showed significant correlations. As a result of criterion validity to analyze AUROC, it was 0.68(p<.001) and less accurate. Its optimal cut-off points were 17 and sensitivity according to them was 0.59, and specificity was 0.72, respectively. However, reminiscence function according to demographic variables did not show any significant differences. Therefore, it is expected that RFS-S will be used as a supplemental diagnosis instrument with higher reliability and validity for discerning differences between normal and mild cognitive impairment and as a useful one to verify effects of reminiscence therapy.

The purpose of this study were to identify the quality of life for the mothers of hospitalized chronic pediatric patients, and to explore the factors affecting the QOL of those mothers. The subjects were 201 mothers whose children had hospitalized at one University hospital with chronic diseases. Data were collected from the December, 1997 to December, 1998. We used a revised QOL instrument consisting of 34 items, 5 point likert scale based on the Noh's QOL instrument. The revised QOL consists of six subscales, those are physical status and function, self esteem, emotional status, economic status, relationship with family members, and relationship with neighborhood. Data were analyzed by t-test, ANOVA, Pearson's correlation using SPSS-PC. The results were as follows: 1. The mean score of quality of life for the mothers of chronic pediatric patients was 100.31, and item mean was 2.95. In subscale analysis, item mean of economic status was the lowest, and that of relationship with family members was the highest. 2. Correlations between characteristics of chronic pediatric patients, their mothers and QOL of mothers were as follows; 1) Total QOL of mothers had a significant positive relationship with progressing time relapse after diagnosing and age of mothers. There was a significant negative relationship between the total QOL of mothers and number of hospitalization of their children. 2) QOL on self esteem and economic status had a significant relationship with age of pediatric patients, the time relapse after diagnosis, and age of mothers. Total number of family members and QOL on economic status showed a significant positive relationship. QOL on emotional status, economic status, and relationship with family members of mothers showed negative correlations with the number of hospitalization of their children. 3. Followings were the result of difference in QOL among different demographic cha- racteristics of the subjects. 1) QOL on economic status of mothers was significantly higher when fathers of pediatric patients had jobs. 2) Total QOL score, QOL on emotional status, and QOL on relationship with neighborhood were significantly higher when mothers of pediatric patients had spouses. 3) QOL on self esteem of mothers was significantly higher when mothers had religion. 4. Followings were the result of difference in QOL among different diagnosis of the children. 1) Total QOL score of mothers whose children had congenital heart disease was higher than that of mothers whose children had leukemia and cancer. 2) QOL on emotional status, economic status, and relationship with family members of mothers whose children had congenital heart disease were higher than those of mothers whose children had leukemia, cancer, and epilepsy.

The purposes of the present study were to determine the difference of functional outcome, and to identify factors associated with functional difference in patients with stroke. The sample consisted of 56 stroke patients who had received physical therapy at the physical therapy unit of the Dongeui Medical Center in Busan city between January 2000 and June 2002. Stroke patients were evaluated by physical therapists 3 times; The first day in physical therapy (PT) (T1), one month after the first day in PT (T2), and two months after the first day in PT (T3). Functional status was assessed with the Functional Independence Measure (FIM) instrument, a validated instrument for documenting the severity of disability and assessing the outcome of rehabilitation treatment. Functional gain was calculated over T2-T1, T3-T1, and T3-T2. SAS statistical software was used for the analysis. The Student's t-test, paired t-test, analysis of variance (ANOVA/Tukey and Scheffe), and analysis of covariance (ANCOVA) were used to examine the functional difference in variables. Repeated measures ANOVA was also used to analyze the functional difference by time (T1, T2, and T3). Multiple regression analysis was performed to determine the effects of independent variables on the difference of functional outcome as defined by the FIM score. A total of 56 stroke patients were evaluated, their average age${\pm}$standard deviation was $61.6{\pm}9.3$ years (range: 40~81 yr). The functional status of patients who received physical therapy for about 2~3 months was significantly improved (mean FIM scores, $20.5{\pm}1.8$, $28.9{\pm}1.9$, and $8.41{\pm}1.1$ points for each time period, respectively) (p<.0001). Diabetes was significantly associated with the FIM score for T2-T1 (p<.05). The type of diagnosis was significantly associated with the FIM score for T3-T1 (p<.05). Gender, smoking, and the FIM score on admission were significantly associated with the FIM score for T3-T2 (p<.05). In conclusion, gender, smoking, diabetes, the type of diagnosis, and the FIM score on admission were significantly associated with improved FIM scores. We recommend that further research should explore the functional outcome by using larger sample sizes, longer follow-up periods, and more sensitive assessment instruments.

The study investigates the type of organizational culture, using the organizational culture assessment instrument(OCAI) developed by Cameron and Quinn based on the competing value model(CVM), and analyzed the gap between current and desirable organizational culture empirically. The analytic results show that while the organizational members prefer the relational organizational culture as a dominant organizational culture on the current level. Also they prefer the relational organizational culture as a desirable organizational culture on the future level. In addition, the diagnosis of organizational culture by the type of status reveals that while the public educational personnel and staff recognized the relational organizational culture as a strong culture, the local public service employee identified the hierarchical culture as a dominant culture on the current level. Those findings suggest the following implications. First, the sustainable management of organizational culture requires the suitable strategic tools. That is to say, they need to introduce and carry out practical strategies to sustain change and control for each type of organizational culture. Second, despite the fact that the balance among four types of organizational culture is needed the strategy to reinforce the dominant culture, considering the types of status and affiliation.
