The leiomyomas of the vulva are rare benign tumors the incidence is 0.024%~0.55% in women. There are no relationship between leiomyomas of the vulva and uterus. But there are some reports that leiomyomas of the vulva and uterus simultaneously. The leiomyomas of the vulva present without symptoms and excision with biopsy is treatment of choice. Tumors of the gynecological apparatus may present without symptoms, or they may mimic other common gynecological conditions. Because of this, any vulva mass must be considered cautiously. We reported this case with a brief review of the concerned literatures.

기술역량, 혁신성, 관리역량이 구매IOS성과에 미치는 영향

박해철,김기윤,나관식 한국정보사회진흥원 2006 정보화정책 Vol.13 No.2

IOS(Inter-Organizational Information Systems)는 전통적인 제조업을 비롯한 모든 산업분야에서 폭넓게 활용되고 있으며, 광범위하게 흩어져 있는 공급자, 유통망, 고객들을 연결해 주는 주문시스템이 일반적이다. 실무적으로는 EDI나 SCM 등과 같은 형태로 구현되고 있는 이 IOS가 최근 들어 이들 조직 간의 거래활동을 혁신적으로 변화시키고 있지만, 실제 적용에 도움을 줄 수 있는 구매성과에 관련된 연구는 거의 이루어지지 않고 있다. 따라서 본 논문의 연구목적은 기술역량, 혁신성, 관리역량이 구매IOS 성과에 미치는 영향을 검정하고자 하는 것이다. 이를 위해서 기존 연구로부터 네 개의 가설을 도출하여 연구모형을 수립하였고, 구조방정식모형으로 이를 검정하였다. 검정결과 혁신성과 관리역량은 구매IOS품질에 직접적으로 관련이 되어 있으며, 이 구매IOS품질은 구매성과를 향상시키는 것으로 나타났다. 하지만 기술역량과 구매IOS품질과의 관계에서는 기업 규모에 따라 상이한 결과를 보였다. 이 결과에 의하면 대기업의 경우 중소기업과는 달리 기술역량이 중요한 요인인 것으로 검정되었으므로, 개별기업이나 관련기관에서 IOS 구축을 위한 정보기술 투자정책 수립 시에는 기업규모에 따라 차별화된 접근방법이 요구된다.

It is generally accepted that ethanol has the diuretic action in the human beings by the inhibition of ADH(antidiuretic hormone) secretion. However, contribution of ethanol to body fluid change and blood ethanol curve in the rat has not been studied satisfactorily. Thus, the following experiment was performed to examine the change of blood ethanol concentration and the body fluid after ethanol administration in the Sprague Dawley female rats which were divided into 2 groups: control and ethanol-administered group. A single dose of one ml of 25% ethanol (ethanol group) or water(control group) per 100gm body weight was administered. On the day of experiment, the rat was anesthetized with ether and catheterized in the femoral artery for sampling of arterial blood. The catheter was filled with heparin solution. Blood sampling was done at least 3 hours after the surgery. Blood ethanol concentration was measured by the alcohol dehydrogenase enzyme method and ADH by radioimmunoassay. The results obtained are summarized as follows. The formula representing the blood ethanol concentration, C(mg/dl), after ethanol administration as a function of time, t(hour), was C=126.57(1-e^-2l.036t)-16.59t and showed more rapid absorption and metabolism of ethanol in the rats than in human beings. Plasma ADH concentration was 3.4±0.4pg/ml at rest but was decreased significantly at 30 and 120 minutes after ethanol administration. A gradual decrease in hematocrit was produced by continuous blood sampling but ethanol group showed higher hematocrit values than control. A significant increase of corrected osmolality was observed compared with the control, particularly at 30 and 60 min after ethanol administration and urine volume was also increased in the first 2 hours. From these results it was concluded that in the rats the rates of ethanol absorption and metabolism was rapid and ADH secretion was decreased for 2 hours after ethanol administration. Subsequently, the solute free urine volume and corrected osmolality was increased followed by plasma volume shift from the vessel. After 2 hours, though blood ethanol concentration was still high, corrected osmolality and urine volume was recovered to the original value.

We studied the relationship between a civil affair occurrence of bad smell and meteorological conditions around Seongseo district for recent 2 years. The results were as follows; (1) The civil affair occurrence days of bad smell were concentrated from May to August. (2) Daily mean temperatures were mostly 20~28℃ and daily mean relative humidities were 60~80%. (3) Wind speeds were mostly less than 2m/s(75%). and wind directions were southerly winds(50%). It was hardly occurred for relatively well-ventilated conditions in cases of wind speeds 2m/s over. And the Lagrangian particle dispersion model were used to figure out the transport route in a civil affairoccurrence days of bad smell. It was found that the south-western winds transported the bad smelling materials from Jungni-dong(the place of source) to the housing complex located along a piedmont district.

This study was designed to evaluate prevalence of allergen-specific antibodies in healthy adults. During Mar. ~ Aug. 2001, 1,925 subjects visited for medical check-up, were inquired to fill out a standardized questionnaire. Among them, 200 subjects who had no current and past allergic disorders were randomly selected for rhe current study and examined for allergen-specific antibodies using Korean inhalant panel of MAST-CLA allergen-specific IgE assay. Among them, 170 persons (85.0%) did not have any positive allergen-specific antibody. Each positive rate of 35 allergen specific antibodies was usually less than 3%, except Cockroach Mix (3.5%), Dermatophagoides farinae(8.5%), Dermatophagoides pteronyssinus(6.0%). Among 30 positive subjects, 19(63.3%) showed one or two allergen-specific antibodies. Although atopic subjects in non-allergic population were not common, few of them showed allergen-specific antibodies in Korean inhalant panel of MAST-CLA. Our results suggested that the standardized questionnaire and MAST-CLA could be an useful tool of a screening test for allergy, showing high specificity and sensitivity.

양해승,박현식 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.1

최근 NATM에 의한 터널건설이 증가됨에 따라 계측의 중요성이 강조되고 있다. 지하에 안전하고 합리적인 터널을 건설하기 위해서는 사전지질조사 결과와는 다른 지질하적 조건에 적합한 지보를 설계하는 것이 필수적이다. 그러므로 계측은 터널 주변암반의 특성을 평가하기 위해서 매우 중요하다 터널굴착의 안정성은 일반적으로 암반의 지질학적 구조(단층, 절리, 파쇄대)에 영향을 받는다. 암반의 거동은 암반내에 존재하는 파쇄대의 역학적 특성과 분포에 의해 좌우된다. 파쇄대가 존재하는 터널내에서 연약한 암반주위의 굴착은 팽창성 지압이 발생하여 터널시공에 어려움을 겪고 있는 실정이다. 본 논문에서는 보조공법이 수행된 파쇄대 주변암반에서 내공변위, 천단침하, rock bolt 축력 그리고 shotcrete 응력의 현장계측이 수행되었으며, 각 계측항목별로 해석치, 현장계측기 그리고 허용기준치로부터 변형여유량을 산정하여 터널굴진에 따른 터널의 안정성을 평가하였다. As the construction of tunnelling by NATM increased, the importance of measurement is being emphasized. For tunnelling safely and reasonably construction in underground, it is essential to design the support suitable to the geological conditions that could be different from the results of pre-investigation. Therefore, it is very important to evaluate the characteristics of rock mass around tunnel in excavating site. The stability of the tunnelling is generally affects by the geological structures(fault, joint and fracture zone) of the rock mass. The behavior of rock mass was dominated by the mechanical properties and distribution of fracture zone within the rock mass. The excavation around the fragile rock mass in the tunnel existing fracture zone is difficult for tunnel construction generated the expansibility earth pressure. In this study, in-situ measurement of convergence, crown settlement, rock bolt axial force and shotcrete stress were conducted in rock mass around fracture zone executed assistant construction method, assessed the stability of tunnel from analysis values, in-situ measurement values and administration criterion values for measurement items. The design of support pattern around fracture zone within the rock mass was appropriated.

일상생활에서 모발염색은 흔히 접할 수 있는 미용의 한 종류로 특히 젊은층을 중심으로 폭발적으로 유행하고 있다. 염색을 위항 사용하는 약제는 표백제와 발색제 등 각종 화학약품이 사용되고 있으나 이로 인한 건강장해에 대한 연구는 그리 많지 않다. 저자들은 염색이 인체의 모발건강에 미치는 영향을 파악하기 위하여 염색과 관련된 주관적 증상과 모발의 변화에 대한 실험적 연구를 시행하였다. 동국대학교 경주 캠퍼스 재학생 80명을 대상으로 설문조사를 시행하여 염색 유 ·무 및 염색 후에 경험한 증상에 대해 설문 조사하였고, 의과대학 재학생 46명을 대상으로 피부 반응 테스트를 실시하였다. 또한 염색 전후의 모발 탄성도를 측정하였고 모발의 상태를 파악하기 위해 전자 현미경검사를 실시하였다. 설문조사 결과 염색 전에 비하여 염색 후 안구혼탁, 안구건조, 시력저하, 발진 및 접촉성 피부염, 모발손상, 모근손상 등의 증상을 더 많이 경험한다고 호소하였다(p<0.05). 모발손상과 모근손상은 헤어드라이어 사용 빈도에 따라 증가하는 것으로 조사되었다(p<0.05). 피부반응검사에서 가려움증이 가장 많은 증상이었으며 이는 여성보다는 남성에서 높은 것으로 조사되었다. 염색 전후의 모발장력은 염색 전 134.5±10.37g, 염색 128.0±30.69g, 염색 이틀 후 112.5±19.69g으로 나타났다. 염색 전후의 모발의 전자현미경 케라틴 층이 현저히 감소하고 모발이 가늘어지는 차이를 보였다. 염색은 모발손상, 모발 케라틴 손상 및 모근 손상, 발진 및 접촉성 피부반응, 안구혼탁, 안구건조, 시력 저하를 유발한다. 따라서 염색약으로 인한 손상에 대한 주의와 예방이 필요하다고 생각한다. 예방대책으로 염색 전 피부테스트를 통한 적합성 여부를 판단하는 것이 필요하며 가급적 염색을 피하는 것이 좋을 것이다. 염색약에 발암물질이 포함되어있다는 보고도 있어 염색 제조사의 철저한 실험과 염색 물질의 선별이 염색으로 인한 부작용을 최소화하는데 중요한 역할을 할 것이다. Hair coloring has became one of the most popular cosmetic activities to younger generations during last decade. However, there are few studies on the health effect of widespread use of chemical dyes. This study was conducted to study the effects of hair coloring dye on hair and other systems. We conducted a questionnaire survey of 80 persons in Kyongju campus, Dongguk University. We have done open patch skin test on 46 medical students. We also conducted scanning electron microscopy to examine the hair strength and structure before and after hair coloring process. Injury of hair and hair bulb, contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity were the main symptoms complained after hair coloring (p<0.05). Injury of hair and hair bulb were increased by frequency of hair-dryer use(p<0.05). In open patch test, pruritus was complanined by more than half of the subjects. Mean strength of hairs before and after hair coloring was as follows; 134.5 (SD 10.37)g before hair coloring, 128.0 (SD 30.69)g immediately after hair coloring, and 112.5 (SD 19.69)g after two days. The scanning electron microscopic findings of hair surface before and after hair coloring showed decreased keratin layer and thinning of the hair. Hair coloring induces injury to hair, its keratin layer, and hair bulb as well as contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity. Therefore, we think that precaution is needed in use of hair coloring dye. To prevent complications induced by hair coloring dye, it is necessary, especially to those with allergy or skin disorders, to perform skin test before action and avoid hair coloring whenever possible. Longterm health effects of hairdye should be studied and manufacturing companies should try to minimize complications induced by hair coloring dye.

Pelvic inflammatory disease (PID) is a disease that affects young, sexually active, reproductive age women. Most pathogens are Chlamydia trachomatis and Neisseria Gonorrheae transmitted sexually. One of serious acute complication of PID is tubo-ovarian abscess (TOA) that involves the fallopian tube, ovary and adjacent structures (eg, bowel, pelvic peritoneum). The microbiology of TOAs is polymicrobial with anaerobic organisms and causal organisms of PID. Common anaerobic organisms are Peptostretococcus spp, Bacteriodes spp, Prevotella spp, Escherichia coli and aerobic streptococci. Treatment is necessary to admission for intravenous broad-spectrum antibiotics and surgery is often reserved for patients with suspected rupture or patients who fail to respond to antibiotics. So, we reported this case found pelvic abscess due to ruptured tube-ovarian abscess.
