This paper aims to help the teachers select the textbook and provide them with the basic teaching materials as an ideal model by analyzing the organization (its element and appropriateness), volume amount, experiment matter, and the contents of the highschool chemistry textbooks, which have been revised in accordance with the 5th amended curriculum. The results of the analogy are as follow 1. Organization (its element and appropriateness) : Though having some distincitive characteristics, all the textbooks have almost the same introduction, development, summary, and further study, which are appropriate for the textbook model. 2. The volume amount: All the textbooks have almost the same frame, but s a big difference in such things as the number of pages, of pictures and charts, of Gothic terminology, and relative importance of each chapter. And all the materials such as pictures and photos are black-and-white, which we think are less helpful to the students` study. 3. The experiment matter: There`s a geat difference in the number, kinds, ratio contents and subject of experiment in each chapter. And there are some distinctive characteristics in the type, level, method, and investigative skills of the experiments. 4. The contents : There are considerable differences in the additional and reduced sections. Therefore, which book is selected is very important, and the teachers should not skip any class-work.

Wild edible plants are consumed as raw and/or processed. Analytical data for raw biologically functional compounds were relatively well established. The changes on functional compounds during processing are, however, not well studied. This study was carried out to investigate the change of the quality of wild edible plants, Pimpinella brachycarpa(Chamnamul) at various conditions. Samples were blanched at the salt concentration of 0%, 1% or 2% for 1, 2, and 3 minutes each. The biologically active compounds, vitamin C, β-carotene, chlorophyll, flavonoids, polyphenols and minerals were analyzed. The concentration of vitamin C in Chamnamul decreased as blanching time increased. Beta-carotene in Chamnamul showed high concentration when Chamnamul was treated under longer blanching time. Higher salt concentration of blanching water, however, resulted in the increased concentration of β-carotene in the blanched Chamnamul. Higher salt concentration of blanching water also reduced the loss of total flavonoids and total polyphenols from the blanched Chamnamul. The change of colors in the blanching water seemed to be corresponding to those of total flavonoids and total polyphenols concentrations in the blanching water.

This study was conducted to determine the desirable thawing method and storage time of Nokchaborijook(gruel made of barley, rice powder and Green tea) which made of optimum conditions as the 5.8% Green tea and 15 seconds grinding time. Decision on desirable storage time(10, 20, 30, 40, 50days), thawing method(water bath, microwave oven) of frozen Nokchaborijook were determined by sensory evaluation and physicochemical attributes. As the storage time became longer, moisture and flavonoid contents were decreased. Viscosity, the ratio of water seperation, spreadability of Nokchaborijook which stored at 30 days showed great differences between the two thawing method. Among the sensory characteristics, desirability for overall, flavor, and texture were decreased as the storage time became longer. As a result of consumer test, Nokchaborijook thawed at water bath was more desirable than Nokchaborijook thawed at microwave oven. According to the results, frozen Nokchaborijook can be using as a supplement of dietary fiber and flavonoid for the health and be using convenience food.

Injury to associated structures is expected to worsen the prognosis of ACL tears. Meniscal injuries are well known to coexist in knees with both acute and chronic ACL injuries. However, it is not conclusive whether the likelihood of encountering a repairable meniscal lesion diminishes as the time from injury increases. W e reviewed records of 127 patient receiving an arthroscopically assisted stabilizing procedure for an acute and chronic ACL injury incurred while skiing, soccer, traffic accident to associated meniscal injury. All patient had undergone arthroscopic evaluation. We classified acute injury as injury less than 3 months old at time of surgery, and chronic injury as more than 3 months old. Acute injuries were 88 cases and chronic injuries were 39 cases. In 55 ski-related injuries, 41 knees were acute and 14 knees were chronic. Fourteen(34%) meniscal tears were noted in chronic cases. In 42 soccer injuries, 20 knees were acute and 22 knees were chronic. In acute cases, 14(70%) meniscal tears were noted and in chronic cases, 14(64%) meniscal tears were noted. In 30 traffic accident injuries, 27 knees were acute and 3 knees were chronic. In acute cases, 19(70%) meniscal tears were noted and in chronic cases, 2(67%) meniscal tears were noted. There was strong trend of the increased incidence of medial involvement in the non-skiers than in the skiers, In the type of meniscal tear with acute ACL rupture, 33 of 52 meniscal were longitudinal tear, 6 were horizontal tear, 4 were radial tear(only in lateral meniscus) and 9 were complex tear. In the pattern of meniscal tear with chronic ACL rupture, 15 of 37 meniscal were longitudinal tear, 3 were horizontal tear, 1 was radial tear(only in lateral meniscus) and 18 were complex tear(medial meniscus 16, lateral meniscus 2). In the treatment of torn menisci, 29 of 52 meniscal tears were treated by conservative treatment and meniscal repair, 21 meniscal tears were treated by partial menisectomy and 2 meniscal tears were treated by subtotal menisectomy in acute injuries. In chronic injury, 10 of 37 meniscal tears were treated by conservative treatment and meniscal repair, 18 meniscal tears were treated by partial menisectomy and 9 meniscal tears were treated by subtotal menisectomy. There was no total menisectomy. As the time from injury increased, the medial meniscus tears were severe and were more likely to require menisectomy.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

The determination of peripheral nerve conduction velocity is and important part to electrodiagnosis. Its value as neurophysiologic investigative procedure has been known for many years but normal value of median and ulnar motor nerve was poorly reported in Korea. To evaluate of median and ulnar motor nerve terminal latency, amplitude of CMAP(compound muscle action potential), conduction velocity and F-wave latency for obtain clinically useful reference value. 71 normal volunteers(age,19-65 years;142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking Ⅱ was use for detected terminal latency, amplitude of CMAP, conduction velocity and F-wave latency of median and ulnar motor nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation, independent t-test was used to compare between Rt and Lt side also compare between different in genders. The results are summarized as follows: 1. Median motor nerve terminal latency was right 3.00ms, left 2.99ms and there was no significantly difference between right and left side and genders. 2. Median motor nerve amplitude of CMAP was right 17.26mV, left 17.50mV and there was no significantly differences between right and left side and genders. 3. Median motor nerve conduction velocity was right 57.89m/sec, left 58.03m/sec and there was no significantly difference between right and left side and genders. 4. Median motor nerve F-wave latency was right 25.74ms, left 25.59ms and there was significantly differences between genders. 5. Ulnar motor nerve terminal latency was right 2.38ms, left 2.45ms and there was significantly differences between right and left side. 6. Ulnar motor nerve amplitude of CMAP was right 15.99mV, left 16.02mV and there was no significantly differences between right and left side and genders. 7. Ulnar motor nerve conduction velocity was right 60.35m/sec, left 59.73/sec and there was no significantly differences between right and left side and genders. 8. Ulnar motor nerve F-wave latency was right 25.53ms, left 25.57ms and there was significantly differences between genders.
