In the head and neck area, there are so many sensory nerves, which are sometimes injuried iatrogenically or inadvertently so that involved patients complained of the loss of sensations. In such cases, it is important to judge the degree of injuries and regeneration of nerve for better diagnosis and treatment. Seddon and Sunderland's classification, which is commomly used, is focused on histological change and nerve conduction. As times goes by, it is difficult to access patient's sensory disturbance by this method. Until now, so many methods such as contract threshold, direction, two-point discrimination, pin prick, thermal discrimination and current perception threshold have been introduced for sensory evaluation. However, there hasn't been enough information regarding each methodology nor integrated standard methodology for the measurement. the purpose of this study is to get Korean adult normative sensory values of lower lip,chin and tongue using modified methods of contact thershold, ditection, two point discrimination, pin prick, thermal discrimination and assess degree of regeneration of sensory nerve damage.

Elementary science textbooks are the major instructional materials which contain sceientific objectives to be acquired by students. The purpose of this study is to analyze the development system, to evaluate the inquiry activity in current elementary science testbooks, and to make suggestions for the improvement of them. The questionnaires were administered to 116 subjects that participated in development of the 5th elementary science textbooks, and 86 of the subjects responded. Based on the data gathered and analyzed in this study, the major findings are as follows. First, regarding the analysis and evaluation of elementary science textbooks. 1. The instructional objectives in elementary science textbooks are analyzed. The proportions of comprehension objectives is 38%, scientific inquiry process objectives 21%, experimental skills objectives 7%, scientific attitudes and interests objectives 4%. 2. The science concepts in elementary science textbooks of the 3rd grade required the preconcrete operational level(82%) and of the 6rd grade required the postconcrete operational level (73%) by J. Piaget. 3. The inquiry activities in elementary science textbooks are emphasizing gathering and organizing results and evaluation, and hypothesizing and designing an experiment. Inquiry index of the elementary science textbooks is 76. This is significantly higher than 35∼50 of America and U.K. 4. The number of questions per class hour is mostly three, and most of them require the students to explain phenomena in nature or in experiment Second, regarding the development system of elementary science textbooks. 1. The budget for and the period of the development of elementary science textbook should be expanded. 2. For the improvement of elementary science textbooks, more abundant resources and time should be used for the basic study and the field trial of textbooks. 3. The elementary science textbook must include the affective objectives as well as the scientific knowledges and scientific inquiry skills. 4. It is not desirable to assign equal number of pages to the content of physics, chemistry, biology, and earth science. 5. Closer cooperation system is needed among the ministry of education, development research center and the field trial schools.

요추부의 Transpedicular Screw를 이용한 수술의 합병증

정진명,한종우 대한신경외과학회 1991 Journal of Korean neurosurgical society Vol.20 No.12

46 consecutive patients underwent application of transpedicular screw since June 1988, and had follow-up at least for 6 months. 15 cases(32.6%) of them had one or two complications. There were 5 wound infections, which seemed to be caused by long operation time, wide metal implant area and personal predisposing factors. There were 5 patients with screw breakage. The exact screw alignment and avoidance of vigorous distraction are considered to by important in minimizing screw breakage. 2 patients had screw loosening, which could be reduced by proper placing of screw and methy1 metacrylate enforcement. Nerve root irritation and adjacent disc space degenerative change were developed in 5 cases. Discspace changes were induced by stress transfer after rigid fixation. Finally, postoperative severe wound pain which persisted for a long time was another troublesome problem.

In dorsal laminectomy for the surgical treatment of thoracolumbar disc disease in dog, the bur could slip into the vertebral canal. For the decrease of this probability of danger, osteotome was used with instruments such as bur and rongeur in dorsal laminectomy. At thoracic vertebrae (T10-T11) and lumbar vertebrae (L5-L6) area, dorsal laminectomys were performed in a dog. In observation for 3 months after surgery, the dog revealed healthy physical condition. For the confirmation of healing condition at 3 months after dorsal laminectomy, two surgical sites were exposed by incision. Excellent healing response was observed with no adhesion and fibrosis in the vertebral canal.

평야지재배 적응 조생종 벼 품종의 선발 및 품종 육성의 기초 자료로 활용코자 극조생종(1품종)과 조생종(10품종) 및 준조생(3품종)등 총 14품종을 산간지(운봉)와 평야지(익산)에 지역별 표준재배법으로 공시한 결과, 1. 극조생종 및 조생종들은 감온성이 커 산간지에서 출수가 빠르나, 준조생종에 속하는 상미벼, 영덕34호, 히또메보레 등은 감광성이 감온성보다 커, 평야지재배에서 4일정도 빨리 출수하였다. 2. 수량성은 대부분의 품종들이 산간지재배에 비해 평야지 재배에서 높았고 대체로 출수가 빠른 품종일수록 지역간의 수량차가 크게 나타났으며, 출수가 다소 늦은 준조생종들은 산간지와 평야지의 재배에서 수량차가 크지 않아 산간지 뿐만 아니라 평야지에서도 적응성이 높았다. 3. 단백질함량은 숙기가 다소 늦은 품종일수록 낮은 경향을 보였고 산간지보다는 평야지에서 낮았으며, 품종간에는 오대벼, 운봉30호, 영덕34호, 신석조생, 상미벼 등이 함유량이 낮았다. 4. 식미치는 산간지재배가 평야지에 비해 보다 높게 나타났고, 출수가 늦을수록 높았으며, 지역간 차가 크게 나타난 품종은 극조생종인 키라라397이었고, 출수가 늦은 상미벼와 히또메보레는 차가 적었다. 5. 산온도와 수량과의 상관은 산간지에서만 영향이 있을 뿐 평야에서는 영향이 적고 일사량과 일조시수가 수량에 보다 상관성이 높았으며, 식미치는 적산온도와는 부의상관, 생육 일수와는 정상관을 보였다. This experiment was carried out to clarify the difference of rice yield and the quality of rice in southern plan area and in alpine area. Yield and quality of fourteen early varieties were investigated under the different transplanting dates and planting densities in southern plan area(Iksan) and in alpine area(Unbong). In the alpine area, extremely early variety and early varieties headed early compared to the plain area, but medium early varieties headed about 4 days late unlike the alpine area. The yield difference of most early varieties including Kilara 397 of extremely early flowering variety were greater in plain area than in alpine. The different of yield between plain and alpine area was less in varieties with Sinseogjosaeng, Odaebyeo, Akidagomachi, and Yeungdeuk34. The rate of protein was lower in plain area than alpine and more lately flowering than early, but palatability of milled rice was higher at the alpine area and more lately flowering varieties. Correlation coefficients between yield and meterological data during maturity, yield shower the significant correlation with integrated solar radiation and sunshine hours at cultured in southern plan area, but it showed only cumulative temperature in alpine area. Palatability of miller rice was positive correlation at growth duration but negative correlation at cumulative temperature.

Cd+Se 혼합물의 열화학적 성질을 DSC를 이용하여 조사하였다. Cd과 Se분말을 이용하여 분석한 결과 Cd이 녹기 전 까진 CdSe의 형성이 관측되지 않았지만, Cd의 녹는 점 이상에서는 온도와 반응시간에 따라 상당한 양의 CdSe가 만들어지는 것을 알 수 있었다. 이상의 방법을 토대로 전기 화학적으로 합성한 CdSe박막의 조성을 분석하였다. 일정 전압에서 합성한 CdSe 박막을 DSC로 분석한 결과 Cd,Se 그리고 CdSe의 양을 각각 분석할 수 있었다. The thermochemistry of the condensed-phase Cd+Se=CdSe system was studied by differential scanning calorimetry(DSC). Formation of CdSe was not initiated until fusion of Cd reactant. However, increase of temperature or reaction time resulted in the formation of CdSe although there was no clear exothemic peak. Based on the thermochemistry of Cd+Se system, compositional analysis of electrodeposited CdSe thin films by the DSC was described. Potentiostatic deposition of CdSe thin films contained free Cd, free Se and CdSe depending on the deposition potential. Interesting features of Se thermochemistry were also described.

Until recent time many studies for relationship of dental abnormalities and cleft lip and palate were reported, higher prevalence of abnormality was revealed. The patients with large cleft size had significantly more missing teeth than patients with small cleft size. The tooth that is most usually missed in normal population is the mandibular second premolar, followed by the maxillary lateral incisor and the upper second premolar. The aim of this study was to analyse the prevalence of dental abnormalities and ectopic eruption in patients with cleft alveolus visiting our hospital. Radiographs, dental cast and records from about 60 patients were analysed to find the relation of missing, malformed, malpositioned tooth and delayed eruption and cleft site.
