목적 : 요통환자에서 요통의 유무와 강도를 평가하고자 표면근전도를 이용하여 근육 활동성의 차이를 검증하였고 적외선체열촬영을 이용하여 제표면 온도의 변화를 측정하였다. 방법 : 요통환자군 16명과 대조군 16명에 대하여 요부에 부착한 표면전극에서 얻은 근전도 신호와 적외선체열촬영 결과를 비교하였다. 교란요인의 영향을 배제하기 위하여 연령과 성별 그리고 비만도에 따라 정상 대조군과 요통환자군을 짝짓기하여 각각 16명씩 선정하였다. 결과 : 정적표면근전도 실시 결과 우측의 경우 중앙값이 요통환자군에서 198.1 ㎶, 정상대조군에서는 161.3 ㎶로 통계적으로 유의한 차이가 있었고(p<0.01), 좌측은 요통환자군에서 194.2 ㎶, 정상대조군에서 180.5 ㎶로 유의한 차이는 없었다. 동적표면근전도 실시 결과 재신전시와 굴곡시 근전위의 비가 우측의 경우 요통환자군에서 중앙값이 1.12였고 정상 대조군은 1.39로서 두 군간에 유의한 차이가 있었고(p=0.027), 좌측의 경우도 요통환자군에서는 1.08이었고 정상 대조군에서는 1.21로 유의한 차이가 있었다(p=0.036). 적외선체열촬영결과 ΔT가 0.5 ℃ 이상의 차이가 있을 때 이상이 있는 것으로 정하면, 요통환자군에서는 16명 모두 이상자로 판정되었고, 정상 대조군에서는 16명중 3명이 이상자로 판정되어 민감도는 100 %, 특이도는 81.3 % 였다. 표면근전도를 이용한 요통의 진단은 민감도가 78.6 %이고 특이도가 72.2 %였으며, 적외선체열촬영은 민감도가 100 %였고 특이도가 87.5 %였다. 결론 : 이러한 결과로 볼 때 표면근전도 검사법과 적외선체열촬영은 요통을 간접적으로 평가하는데 도움이 되는 검사법이며, 적외선체열촬영이 표면근전도검사법에 비하여 보다 정확한 검사법으로 판단된다. Objectives : We studied the efficacy of surface electromyography(SEMG) and digital infrared theimographic imaging (DITI) in the assessment of low back pain both(LBP) Methods : We compared electromygraphic signals from electrodes placed in the lumbar area and the digital theimographic images in 16 LBPpatients and 16 control subjects. The LBP patients and the control subjects were matched for age, gender, and body mass index(BMI) to adjust for any confounding effects Results : In the static analyses of SEMG, median value was 198.1 ㎶ for the controls on the right side, and they were 194.2 ㎶ and 180.5㎶ on left side respectively. There was a statistically significant difference between the two groups on the right side(p<0.01), but not on the left side. In the dynamic analyses of the SEMG, the median values of the extension per flexion ratio of right side were 1.12 for LBP patients and 1.39 for controls. and those on the left side were 1.08 and 1.21 respectively. There were statistically significant differences in both sodes(p<0.05). The sensitivity and specificity were 100% and 81.3% in DITI, 78.6% and 72.2% in SEMG. Conclusions : These results indicate that SEMG and DITI are useful methods for indirect assessments of LBP, and that DITI is more sensitive and specific than SEMG.

Purpose : This study was aimed to evaluate the cell cycle arrest and apoptosis induction after irradiation and epidermal growth factor(EGF) treatment in three human epithelial tumor cell lines (A43l, Siha, KB). Materials and Methods : Single irradiation of 2, 5 and 10 Gy was done on three cell lines with 5.38 Gy/min dose rate using Cs-137 irradiator at room temperature. Also, EGF of 10 ng/ml was added immediately after 10 Gy irradiation. Cell growth was evaluated by counting the living cell number using a hemocytometer at 1 day, 2 days, 3 days, 4 days and 5 days after irradiation. Cell cycle arrest and apoptosis induction were assayed with the flow cytometry at 8 hours, 12 hours, 1 day, 2 days, 3 days, 4 days and 5 days after irradiation. Results : Growth of irradiated three cell lines were inhibited in proportion to radiation dose, EGF treatment after irradiation showed various results according to cell lines. On all cell lines, G2 arrest was detected after 8 hours and maximized after 12 hours or 1 day. Amount of G2 arrest was positively dose dependent. However, EGF showed no significant change on G2 arrest. G2 arrest was recovered with time at 2 Gy and 5 Gy irradiation. However, at 10 Gy irradiation, G2 arrest was continued. Apoptosis was detected at 10 Gy irradiation. On EGF treated group after irradiation, A431 and Siha cell lines showed slightly increased apoptosis but there was no statistically significant difference. KB cell line showed no marked change of apoptosis induction. Conclusion : Irradiation effects on cell cycle arrest and apoptosis induction in three human epithelial tumor cell lines, however epidermal growth factor doesn't effect on.

As a part of the improvement of taste and shelf-life, the effects of fermentation temperature on the physicochemical characteristics of mustard leaf kimchi was examined. The setting of fermentation temperature and time in this experiment was as follows : type A-stored in the refrigerator under the constant rate of 4℃ right after preparation, type B-stored in the refrigerator of 10℃, after the progression for 60 days with the same treatment as the type A method, type C-constant fermentation in 10℃, type D-12hrs, fermentation with the same treatment as the type C method and stored under 4℃ condition and type E- 36hrs. fermentation in 10℃ refrigerator and stored under 4℃ condition. The result was as follow: the value of pH of the mustard leaf kimchi was 5.24 right after preparation. As the pH values of the mustard leaf kimchi in the palatable pariod, 4.6∼4.8 have been reported by preinvestigator. In this experiment, the palatable period when the values of pH were 4.6∼4.8 were as follows : type A - 78∼96 days, type B- 66∼72 days, type C- 18∼30 days, type D- 68∼80 days, and type E- 60∼78 days. In these periods, total acid content were as follows : type A- 0.78∼0.82%, type B- 070∼0.90%, type C- 0.73∼0.80%, type D- 0.79∼0.80%, and type E- 0.74∼0.80%. In the initial period of the fermentation of the mustard leaf kimchi the values of pH were lower and total acid content were higher than those of oriental cabbage kimchi, and the both times required to reach the palatable period and keep the palatable period was long. Total vitamin C content decreased according to the increase of fermentation days, but at the palatable period it increased in the range of 12.5∼20.0㎎%, after that, it decreased slowly, type A showed that the value decreased slowly, and type B and type D showed low values. About the color of the mustard leaf kimchi, the values of L decreased at begining then increased again, that of a decreased, on the other hand, that of b increased. On the microbiological properties of the mustard leaf kimchi, as the fermentation progressed, the cell number increased. The total and lactic acid bacteria cell numbers in type E were 3.0×10 exp(8)∼1.0×10 exp(10) respectively in the palatable period and these numbers were the highest values.

Diffusion coefficients of dye was increased by adding organic components and electrolytes as solvent to dye-water system. We measured diffusion coefficients by treating the ternary system of dye-solvent-water as a pseudo-binary system of dye-water and solvent. All experiments were made with the diaphragm cell of Whatman 42 filter paper and sintered glass when solvent was organic components and electrolytes respectively. The experimental results showed that diffusion coefficients of dye nearly agreed with the approximate equation related to the solubility of dye. Diffusion coefficients of dye were increased when solubility of dye to the water was larger than that of organic component to the water. There was similar tendency between diffusion coefficients of orange Ⅱ and that of electrolyte when solvents were electrolytes. In order to increase diffusion coefficients of dye, electrolytes were more favorable than organic components as solvent. But in the case of urea as solvent, diffusion coefficients of orange Ⅱ were increased maximum seven times.

〈Objective〉 This study were carried out to study to assess the relationship between job characteristics, general characteristics, health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. 〈Methods〉 We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item self- administered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) 〈Results〉 Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12~4.11), and those of passive group and active group were 2.01(95 0.83~2.76) and 1.80(95 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. 〈Conclusion〉 The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.

Fatty acid compositions of Setaria italica, Panicum miliaceum and Sorghum bicolor were determined with total lipids extracted. Total lipid content of Setaria italica, Panicum miliaceum and Sorghum bicolor were 3.9%(w/w). 2.7%(w/w) and 2.3%(w/w), respectively. Total lipids were fractionated into neutral lipids, glycolipids and phospholipids by the silicic acid column chromatography. Neutral lipids were the most abundant component. Among fatty acids separated by GC, linoleic acid was determined as a major fraction in Setaria italica, Panicum miliaceum and Sorghum bicolor. Palmitic acid and oleic acid were also separated as second major components. In Setaria italica, behenic acid was separated from the phospholipid fraction and myristic acid from the neutral lipid fraction. Linolenic acid was not detected in all the samples.

본 병원에 내원한 절단된 이하선관 환자 총 20명(남자:10명 여자 10명)중 4명을 제외한 16명에서 추적조사가 가능하였으며 이 중 14명에서 이하선관의 원활한 관통이 이루어졌고 1명에서 관의 폐세기 생겨 2차 수술이 필료 했으며 다른 1명의 경우 농의 배출이 있었으나 항생제 투여와 구강위생등으로 별 다른 문제 없이 치료 되었고 또 1례의 이하선 타석을 치험하여 보고하는 바이다. Due to increasing trend of traffic accident, number of patient has been gradually increased. Facial injury, for its anatomical vulnerability, is most common site of injury and greatly exceeding injuries of other body region in trauma patient. There are occasional report of Stensen`s duct damage accompanying facial injury and much problem can arise when first aid is performed without knowledge of anatomy or concern for patient. Generally, Stensen`s duct located at mid 1/3 portion of line passing through tragus of ear and subnasale, another word, above the masseter muscle. Once deep lacerated wound has occurred in this region, one must suspect damage of Stensen`s duct. Among the 20 patients (Male: 10, Female:10) who have beeb treated at Chonnam National University Hospital for severed Srensen`s duct, 14 cases have obtained favorable result, not counting 4 patients with whom follow-up study was not possible. In unsuccessful cases of two, 1 case required secondary operation due to occurance of ductal stricture. In another case, leakage of pus has been observed but with proper oral care and antibiotic administration, it has been treated withiut any difficulty. Facial nerve injury accompanying Stensen`s duct been frequently observed, buccal branch being the most common site of involvement. Time interval from severance of duct to repairing the duct was 7 to 21 hours on average and time delay of this level has not impose much limit to obtain successful result. Suture material for Dowel, no matter what kind used, has achieved favorable result and time interval of 9 to 21 days given before the removal was long enough to obtain successful operative result without any development of complication. It is generally accepted view that salivary stone is most common disease entity among the salivery glands and ducts, and stone mostly occur in submandibular duct and rarely in Stensen`s duct. We have performed end-to-end anatomosis using a 23 guage polyethylene catheter as a Dowel in severed duct in 20 patients who have been admitted our hospital for cut repair and obtained satisfiable result. In 1 case, we have experienced stone on the Stensen`s duct, therby reporting this case with through reviews of literature.

전북 부안 유천리 청자요지에서 수습된 청자편 11점의 태토 및 유약에 대하여 화학조성을 분석하고, 기 발표되어진 문헌의 청자데이터들을 종합하여, 이와 비교함으로써 본 시료의 도자특성과 및 산지에 대한 정보를 유추하였다. 태토의 주요산화물 분석에는 XRF를 이용하였으며, 유약의 주요산화물분석에는 EPMA를 이용하였다. 태토 중 17개 미량성분의 분석에는 ICP-MS를 이용하였고, 자료의 비교분석에는 Seger식에 의한 방법과 주성분분석법에 의한 통계처리방법을 병행하였다. 태토의 주요산화물에 대한 비교분석결과 유천리 청자는 Seger 식과 주성분분석에서 RO_(2)와 RO+R_(2)O가 6~8 및 0.3~0.38 mole로, 또 높은 SiO_(2)함량과 낮은 Na_(2)O, CaO의 함량으로 전북지역의 데이터 범위에 분포함을 볼 수 있었다. 유약의 주요산화물에 대한 비교분석결과에서는 Seger식과 주성분분석에서 모두 명확한 지역구분이 나타나지 않았으며, 따라서 유천리 청자 역시 명확한 지역적 특성을 구분하기 어려웠다. 태토중 미량성분의 주성분분석에 의한 통계처리결과 광주 충효동 도편들을 제외하고는 뚜렷한 지역간의 구분을 관찰하기 어려웠다. The characterization of chemical properties and analogy of manufactured origin for the eleven celadon sherds collected in Yuchunri, Buan were performed by analyzing their body and glaze compositions and compared with previous data reported. The chemical compositions of the body and glaze were determined by XRF and EPMA, respectively. The trace elements of the body were also determined by ICP-MS. The Seger analysis and PCA were used to compare the major compositions of body and glaze of the potteries we found with previous data. The Celadon sherds from Yuchunri are distributed in a range of Chonnam potteries considering RO_(2) and RO+R_(2)O are 6~ 8 and 0.3 ~O.38mole, respectively and also high in SiO_(2) and low in Na_(2)O and CaO concentrations in the comparison between the potteries for the major compositions of the body. Differences of the chemical characteristics of those potteries between the provinces were not clear in comparison of the glaze compositions and trace element of the body.
