목적 : 3년간 서울시 강서지역의 1개 대학병원에서 입원치료를 받은 성인 급성 신우신염 환자를 대상으로 원인균과 항생제 감수성을 조사하고, 향후 급성 신우신염의 초기 경험적 치료 항생제를 제안하고자 하였다. 방법 : 1999년 1월부터 2001년 12월까지 3년간 고려대학교 의과대학 구로병원에 상부요로감염으로 내원한 16세 이상 환자 229명의 의무 기록을 검토를 통하여, 인구학적 특성, 원인균, 항생제 감수성, 초기 항생제 사용 양상과 입원기간을 조사하였다. 결과 : 연구에 포함된 229명을 118명의 단순 신우신염군과 111명의 복잡 신우신염군으로 구분 하였다. 단수 신우신염의 평균 발생 연령은 38.2세와 복잡 신우신염 56.1세로 복잡 신우신염 환자의 연령이 유의하게 높았다(P<0.001). 양군 모두에서 원인균 중 E. coli의 분리율이 가장 높았으며 항생제 감수성 결과 ampicillin, trimethoprim-sulfame-thoxazole에는 높은 내성률을 보였고, ciprofloxacin, gentamicin, cefotaxime에 대한 감수성은 비교적 높았으나 복잡 신우신염의 경우 단순 신우신염에 비하여 ciprofloxacin, gentamicin에 대한 감수성이 다소 낮은 것을 확인할 수 있었다. 평균 입원 기간, 항생제 투여 기간에 있어서도 복잡 신우신염군에서 유의하게 길었다. 결과 : 본 연구의 결과 서울의 강서 지역에서 대학병원급에 치료 의뢰되는 단순 급성 신우신염의 치료에 있어 1차 항생제로 3세대 cephalosporin, aminoglycoside, quinolone 중 한가지를 초기 경험적 치료제로 사용을 고려하여야 할 것으로 사료된다. Background : The purpose of this study is to recommend the initial therapeutic regimen for adult patients with acute pyelonephritis (APN) according to the changes of antimicrobial susceptibility patterns of causative microorganisms isolated from patients with APN. Methods : We reviewed medical charts of 229 APN patients, who had been treated at Korea University Guro Hospital from 1st of January. 1999 to 31st of December, 2001. We investigated the demographic data, clinical findings, durations of hospital treatment, antimicrobial susceptibility patterns of the causative microorganisms and initial antibiotic regimens in patients with APN. Results : In this study, 229 adult patients with APN were classified into simple APN patients (118 patients, 51.5%) and complicated APN patients (111 patients, 48.4%). Mean age of patients with simple APN was 38.2±14.1 years old and that of patients with complicated APN was 56.1±14.9 years old. Mean age of patients with complicated APN was significantly higher than that of simple APN patients (P<0.0001). Escherichia coli was the most common microorganism both in simple APN (96.7%) group and in complicated APN (90.6%) group. Antimicrobial susceptibility of E. coli was at the low level of ampicillin (31%/20%) and trimethoprim-sulfamethoxazole (42.6%/34.2%) in each group. In contrast, ciprofloxacin (11.5%/22.7%), gentamicin (16.4%/22%) and cefotaxime (0%/8.2%) resistance remained at relatively lower level. In comparison of simple APN with complicated APN, ciprofloxacin and gentamicin resistances were higher in complicted APN group. Average duration of hospitalization (5.9±2.3 days/8.2±4.6 days) and duration of antibiotic use (12.1±3.9 days/15.3±10.0 days) were significantly longer in complicated APN. Conclusions: The results of this study suggests that 3rd cephalosporin, aminoglycoside or quinolone antibiotic would considered as one of the initial therapeutic regimen for patients with simple APN in southwestern Seoul.

This study evaluated the influence of a desensitizer(MS coat) on microtensile bond strength of different adhesives:a three step adhesive(All Bond 2), a two step adhesive(Single Bond), a one step adhesive(One up Bond F). Non-caries extracted human molars were used. Dentin surface was obtained by horizontal section on mid-portion of crown using a water cooled low speed diamond saw. Teeth were randomly divided into 6 group. AMO(MS coat + All Bond), SMO(MS coat + Single Bond) and OMO(MS coat + One up Bond F) dentin surface were treated with 17% EDTA before bonded adhesive. AMX, SMX and OMX dentin surface were bonded with All-Bond 2, Single Bond and One-up Bond F, respectively. with no previous treatment with MS coat and 17% EDTA. About 1cm high resin composite(Z 250) were incrementally build-up on the treated surface. The specimens for the microtensile test were serially sectioned perpendicular to the adhesive layer to obtain 0.7 × 0.7 mm sticks. 30 sticks were prepared from each group. After that, tensile bond strength for each stick was measured with Microtensile Tester at a 1mm/min crosshead speed. Fractured dentin surfaces were observed under the SEM. The results were statistically analysed by using a One way ANOVA and Tukey's test(p<0.05). Value in MPa were: AMO 44.35±13.21; SMO 39.35±13.32; OMO 31.07±1O.25; AMX 49.22± 16.38; SMX 56.02±13.35; OMX 72.93±16.19. Application of MS coat reduced microtensile bond strengths of both Single Bond and One up Bond F, whereas microtensile bond strengths of All Bond 2 were not affected significantly.

Uterine myoma is the most common solid pelvic tumor in women. Nevertheless, etiology and symptomatology remain poorly understood, and management is inconsistent. In an effort to improve understanding of these aspects of uterine myoma, we have reviewed and analysed the data results obtained from myoma patients at department of obstetrics and gynecology, Wonkwang university hospital during the years 1995 to 1996. The following results have been obtained. 1. During the period the incidence of uterine myoma among 1,116 cases of major gynecologic surgery was 27.2 %. 2. Myoma was observed most frequently in the age group 40 to 49 years and the mean age was 43.6 years. 3. The intramural type was observed in 200 cases (65.8 %), mixed type in 53 cases (17.4 %), subserous type in 29 cases (9.5 %) and submucous type in 22 cases (7.3 %) respectively. 4. The symptoms commonly found in decreasing order were abnormal uterine bleeding (57.3 %), pain or pressure symptoms (53.3 %) and palpable mass (22.4 %). 5. Hypermenorrhea was observed in 96 cases (31.6 %) and there were significant correlations between the presence of hypermenorrhea and the type of myoma, associated adenomyosis. ( p< 0.05 ) 6. There were no significant correlations between the dysmenorrhea and the type of myoma, associated adenomyosis. ( p > 0.05 ) 7. Abnormal electrocardiographic findings were noticed in 18.8 %. 8. Mean hemoglobin level were 10.2 gm/㎗ and less than 10 gm/㎗ was found in 26.6 % and transfusion was performed in 20.8 %. 9. The most frequently associated disease in uterine myoma was adenomyosis seen in 43.4 %. 10. The secondary pathologic changes in uterine myoma were found in 5.0 % and the most common change was hyaline degeneration (3.0 %). 11. The infertility was observed in 10.2 % in which the primary infertility was 6.3 % and secondary 3.9 % respectively. 12. Total abdominal hysterectomy was performed in 84.2 % and vaginal hysterectomy in 11.8 %, myomectomy in 3.3 % respectively. 13.

The smectite-rich clays were found locally in Paleozoic calcareous sedimentary rocks in the Samcheok area. Their occurrences were investigated in detail, and the physico-chemical properties of the clays were also determined by X-ray diffraction, chemical analysis, thermal analysis and cation exchanging experiment. The smectitie clays occur as the fissure filling dyke developed in calcareous semimentary rock and as alteration products of instrusive rhyolite. Most of clays occur at the contact between the sedimentary rock and the rhyolite, and the alteration zone was observed only in rhyolite body close to the contact. Judging from their occurrences, it is believed that the smectite-rich clays in this area were formed by the hydrothemal alteration. The smectite clays from the area are mainly composed of Ca-montmorillinite, and associated with small quantities of quartz, opal-CT and feldspar. The montmorillinites from this area lower in Fe content, and higher in exchangeable Ca ion, compared to those of bentonite from the Yangnam-Yeongil area.

We investigated the physico-chemical and sensory characteristics of Kimchi made with red pepper that was washed and mashed. The pH of juice from Kimchi made with red pepper powder was the highest on the day of Kimchi preparation. In the case of Kimchi made with mashed red pepper, the pH of juice and liquid was lower than that of other samples. A similar decrease in pH of juice and liquid was observed up to the second week of fermentation, but the significant difference between both samples wasn't found. The total acidity of Kimchi with mashed red pepper was significantly increased during early fermentation, but was similar during the second week, compared with that of Kimchi with red pepper powder. From the third week of storage, both juice and liquid from Kimchi made with red pepper powder was relatively increased. L and a value of liquid was highest in the case of Kimchi made with mashed red pepper, but b value was lowest during fermentation. In the case of organic acids. acetic acid and lactic acid contents were increased in Kimchi made with mashed red pepper while fermentation progressed. In addition, citric acid content was constant up to the second week in Kimchi made with mashed red pepper but from the third week wasn't detected in both Kimchi made with mashed red pepper and Kimchi made with red pepper powder. In the case of QDA(Quantitative Descriptive Analysis) profiles, the values of Kimchi made with mashed red pepper were significantly higher than those of Kimchi made with red pepper powder in respect to redness, pungency and fresh flavor immediately after the preparation of Kimchi and during the second week of fermentation, but during the fifth week the values were higher in respect to redness and fresh flavor of Kimchi. Appearance and overall acceptability was remarkably increased in Kimchi made with mashed red pepper, compared with that of Kimchi made with red pepper powder immediately after pickling, during the second and the fifth week of fermentation. Therefore, these results indicate that mashed red pepper increased more citric acid content, L and a value of Kimchi in comparison with red pepper powder, resulting in the good effects on overall acceptability due to the significant increase of redness and fresh flover.

중국유가철학에 있어서의 이성과 욕망의 관계 연구

정상봉,황갑연,전병술,안재호 한국철학사상연구회 2003 시대와 철학 Vol.14 No.2

중국유가철학에서는 공자가 극기복례를 말한 이래 맹자의 과욕론을 제기하면서 욕망의 절제를 강조하였다. 그 근거로는 사람을 도덕이성의 담지자로 규정한 것을 들 수 가 있다. 사람이 살아가면서 욕망을 추구하는 것은 자연스러운 일이다. 욕망을 대표하는 것으로는 식욕ㆍ성욕ㆍ물질적 이익 추구 등이 있지만 욕망의 추구가 도덕이성의 기준, 즉 도리에 합당하지 않다면 욕망을 절제해야 한다는 것이 송대까지의 기본적인 관점이었다. 천리를 보존하고 인욕을 없애야 한다는 신유학의 구호도 사실 공과 사의 기준에 입각하여 주장된 것이다. 그러나 명대에 이후 사회구조에 변화가 생기면서 몸[身]과 욕망[欲]을 중시하는 태주학파가 등장하였고 청대의 왕부지는 욕망 긍정을 주장하게 까지 되었다. 이것은 도덕이성과 욕망의 이분법적 대립구조의 해체를 반영하고 있으며 근대 문화의 초석을 깔았다고 평가할 수 있다. In Chinese Confucianism, Kongzi laid emphasis on Ke-ji-fu-li(克己復禮), and Mengzi insisted upon the theory of unselfishness. It is on the assumption that man has a moral reason innately. As long as we live, it is natural that we pursue our desires, e.g. desire to eatㆍsexual desireㆍthe pursuit of material benefits etc. But if the pursuit of desires didn't appropriate to the standard of moral reason, it needs to control our desires. This is a basic viewpoint till Song Dynasty. The slogan of Neo-Confucianism, "Cun-tienliㆍQu-renyu(存天理ㆍ去人欲)" was based upon the public and private affairs. After Ming Dynasty, as the structure of society has been changed, the school of Taizhou stressed on body and desire. Wang Fu-Zi in Cheng Dynasty affirmed the importance of desires. It represented the destruction of dichotomy between moral reason and desire, and laid the foundation of modern culture.

벼 농사에서 기계화가 어려운 육묘를 못자리 없이 간편하고 저비용으로 할 수 있는 육묘기 개발 및 개발 육묘기의 실용성 평가시험 결과를 요약하면 다음과 같다. 1. 개발 조립식 육묘기는 파종상자 치상선반, 플라스틱판, 부직포와 비닐로 만든 보온덮개로 구성되어 있고 35상자 육묘용 육묘기는 규격이 가로 152㎝, 세로 63㎝, 높이 147㎝이며 무게 75㎏이며, 육묘일수에 따라 육묘선반 간격을 간단히 조절할 수 있다. 2. 개발 육묘기를 이용 육묘시 묘소질은 관행 못자리 모와 비슷하고 결주율는 3.2%로 못자리 육묘상자모 2.8%와 거의 같았다. 3. 개발 육묘기는 대당 20만원정도로 기존 자동화 육묘시설 (198평:7,360상자 육묘기준 및 장비에 비하여 시설비가 43% 절감 된다. 4. 육묘 노력시간은 개발 육묘기는 ㏊당 7.9시간으로 자동화 시설육묘 및 못자리 육묘에 비하여 각각 18%, 76%절감 되었다. 5. 물 사용량은 개발 육묘기 이용 육묘는 ㏊당 2.5kl로 자동화 시설육묘 및 못자리 육묘에 비하여 6~8배 절감되었다. Raising seedling in nursery bed needs not only a lots of time but also labor input which are hard especially to the old and lady farmers. On the other hand, construction of seedling raising facilities such as automated seedling raising house also requires a lots of money. To overcome those problems, a simple seedling raising shelf, which is not necessary for preparation of the seedling raising nursery bed, was developed and its feasibility of seedling raising was evaluated. The dimension of the seedling raising shelf has 152㎝ in length by 63㎝ in width with 147㎝ in height. The shelf is composed of 6 to 7 layers of shelf frame, plastic tray for seedling raising, water supply pipes and white polyester cover. The height of a seedling raising shelf can be adjusted to 6 or 7 layers simply by changing the height of plastic pipes. One unit shelf can accomodate 30 to 35 seedling trays which can transplant about 1000 ㎡ rice field. The seedling height and dry weight of rice seedling grown in the shelf-type seedling raising apparatus was not significantly different from those seedlings grown in the conventional nursery bed. Missing hill percent-age of the seedling grown in shelf-type seedling raising apparatus was 4.3% similar to that of nursery bed of 4.3%. The seeding raising shelf has following advantages. The seedling raising shelf reduces cost of the seedling raising facilities by 43%, labor input hour by 18%, irrigation water saving by 83% versus automated the automated seedling raising house and labor saving by 76% and irrigation water saving as much as 6~8 times versus the conventional seedling raising method of nursery bed.
