The aims of this research study is to clear the differences of the learning effects and the cognition of Home Economics by sex in the middle school and to collect the future-oriented educational datas, after implementing the 6th education curriculum. The results of the study are as follows ; 1. Most of students had the cognition that Home Economics is a subject matter of a needful knowledge and skill for the family life, half students a cultural subject matter for the modern life. The former was supported by female students, the latter by male students. 2. Most of students were interested in actual training fields of cooking and hand-sewing, had a strong interest about a field of physical and social-psychological growth. The differences by sex were statistically significant in these fields. 3. Most of students had positive responses in the learning effects of Home Economics. The most useful field was cooking and the worst was the structure and method of sewing machine. 4. The shortage and the dissatisfaction in the learning of Home Economics were lacking of the actual training hours, the old-fashioned teaching methods and the shortage of teaching materials etc.

The acute and subacute toxicity of New Woohwangchungsimwon(NWCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats(Sprague-Dawley, SPF) were injected intraperitoneally with dosages of 0, 540, 750, 1,070, 1,500 and 3,000 ㎎/㎏. Body weights were significantly decreased at 540 ㎎/㎏ dose group in both sexes and abnormal autopsy findings were founded in both sexes at all treated groups. Intraperitoneal LD_50 of NWCH was 812.3 ㎎/㎏ in male and 872.3 ㎎/㎏ in female rats. In the subacute toxicity study, NWCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800 and 2,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NWCH might be over 2,000 ㎎/㎏/day in this study.

극자외선 리소그래피는 파세대 리소그래피 기술로 유력시 되고 있으며 세계적으로 널리 연구되고 있는 기술이다, 극자외선 리소그래피에서 마스크의 구조는 near-field intensity 분포에 영향을 끼친다, 마스크로 들어가는 빛의 사입사 각도에 따라 흡수체 층과 버퍼층은 그림자를 만들며 이러한 그림자 효과는 극자외선 리소그래피 마스크에서 aerial image contrast를 줄이며 결과적으로 패턴의 위치 이동을 야기시킬 수 있는 중요한 요소로 작용한다. 우리는 극자외선 리소그래피에서 일반적인 사입사 각도인 5˚로 마스크 흡수체 패턴의 옆면을 변형하였다, 변현된 마스크 에서의 전자기파와 반사도는 rigorous coupled-wave analysis를 이용하여 계산하였다. Extreme ultraviolet lithogrphy (EUVL) is believed to be the next generation lithography and so it is seriously under study globally The near-field intensity on the EUVL mask is affected by the mask structure The absorber and the buffer layer make a shadow since the light is shining on the mask at some angle to the normal on-axis This shadow effect in th EUVL mask is an important factor that decreases the contrast of the aerial image and as a result causes line-width variation and pattern shift Among the several possible mask structures we focused on the mask edge slope variation with a typical incident angle of 5˚ We analyzed electromagnetic wave around the mask by rigorous coupled-wave analysis (RCWA) and reflectivity in the modified mask structure

고려대학교 흉부외과에서는 심실보조장치 이식에서 흉골 재절개(re-sternotomy)에 따른 합병증과 사망률을 감소시키기 위하여 우측 개흉을 이용한 독자적인 수술법을 개발하였다 (KU technique). 다양한 동물모델과 사체실험 및 임상적용을 통해 안정성과 유용성을 확인하였으며, 향후 좌심 및 양심보조장치 이식에서 표준기법의 하나로 제안하고자 한다. We have developed a new surgical technique (KU technique) of right thoracotomy for cannulation of ventricular assist devices, which can lessen potential morbidity and morta1ity from re-sternotomy. The technique has been proved to be safe and efficient in various animal models, preclinical cadaver fitting test, and human application. We would like suggest KU technique as a part of standard in implantation of left ventricular or hi-ventricular assist devices.

In contrast to younger patients, geriatric patients are generally considered to be poor risk for anesthesia and surgery and greater care should be taken in anesthetic management, because many have chronic systemic diseases in addition to a decrease in physiologic function. To evaluate geriatric anesthetic experiences, we reviewed clinical recoreds of 1,062 patients aged over 65 out of 21,656 surgical cases performed at Korea University Hye-Wha Hospital from January 1980 to December 1986. THe case were analysed according to age, sex, department, preoperative physical status, anesthetic techniques and agents, duration of anesthesia, operation site, length of hospital stay, laboratory data (Chest X-ray, EKG), associated diseases, postoperative complications and mortality. The results are as follows: 1) Of the 1,062 geriatric surgical patients, 516 cases (48.6%) were 65∼69 years of age. 2) The number of geriatric surgical cases was 1,062, of which 672 (63.3%) were male and 390 (36.7%) were female. 3) Most surgical cases were general surgery (401 cases, 37.8%). 4) The rate of elective and emergency surgery was 78.0% (829 cases) and 22.0% (233 cases), respectively. The ratio of insurance patients (737 cases, 69.4%) versus noninsurance patients (325 cases, 30.6%) was approximately 2:1. 5) The number of general anesthesia cases was 777(73.2%), spinal anesthesia, 244 (23.0%), epidural anesthesia, 21 (2.0%), and brachial plexus block, 5 (0.5%). The anesthetics were thalamonal and meperidine hydrochloride (238 cases, 22.4%), halothane (204 cases, 19.2%) and tertacaine (244 cases, 23.0%). 6) The duration of anesthesia was within 1 hour in 88 cses (8.3%), 1∼2 hours in 421 cases (39.6%), and 2∼3 hours in 291 cases (27.4%). 7) The number of lower abdominal surgery cases was 197(46.8%) and the number of upper abdominal surgery cases was 188(17.7%). 8) Preoperative laboratory findings were as follows: The findings of preoperative chest X-rays revelaed that 219 case (21.4%) were within normal mits, 182 cases (17.8%) had hypertensive heart, and 208 cases (20.4%) had atherosclerosis. The EKG, which was done on 90.8% of the patients, reveled that 333 cases (34.5%) were within normal limits, 77 case(8.0%) showed left ventricular hypertrophy, 65 case (6.7%) showed sinus bradycardia, and 27 cases (2.8%) showed myocardial ischemia. 9) Hypertension (88 cases, 49.4%) was the most commonly associated disease. 10) The total number of postoperative complication case was 73(6.9%). Seventeen cases showed wound infection and delayed skin closure, 19 cases showed pneumonia, and 7 case showed atelectasis. 11) The total number of postoperative deaths was 18 cases (1.7%).

This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.

Metastatic lesions to the oral region are uncommon and account for 1% of all malignancies of the jaw. The current study describes a rare case of a 74-year-old woman who presented with a painful swelling of right facial area. She was a non-smoker and the family history was unremarkable. Computed tomography (CT) and magnetic resonance imaging (MRI) of neck showed about 5.5*5cm sized mass in the right mandible condyle and ramus with total destuction of condyle and invasion into right masseter and lateral pterygoid muscle. It looked like osteosarcoma. Sono-guided biopsy of the mass was performed. The results of the tissue indicated well-differentiated adenocarcinoma. Immunohistochemical (IHC) analysis showed positive for cytokeratin 7, thyroid transforming factor 1 but negative for cytokeratin 20, vimentin. A contrast enhanced chest CT, which was performed to detect the primary cancer, revealed about 4.2cm sized mass in left upper lobe lingular segment and left lower lobe anterobasal segment. The results of IHC stain and images favored metastatic adenocarcinoma from the lung. Moreover, activating mutation of epidermal growth factor receptor (EGFR) was detected (c.2573T>G (p.L858R) in exon 21). Subsequent PET-CT also confirmed other metastatic disease in left humeral head and neck, right level II cervical lymph nodes, and right lower paratracheal lymph node. This case indicates that possible metastatic disease should be suspected in patients presenting with a mandibular mass or swelling although metastatic mandibular tumor is even rare. Because their diagnosis may be the first indication of an undiscovered malignancy at a distant primary site, the clinicians need to pay attention to this point, and evaluate patients who present unusual clinical symptoms thoroughly.
