본 시험의 목적은 대구 경북에 자생하는 헤어리베치로 다수성 조생품종과 중만생품종을 개발하기 위하여 수행하였다. 경북 성주와 경남 사천에서 1998년부터 2006년까지 자료수집 및 순화, 생육이 왕성한 조생 및 중만생계통선발, 상호교잡의 단순순환선발법으로 조생종인 콜드그린과 중만생종인 청파를 육성하였다. 육성종자는 2004년부터 2006년까지 경북성주와 경남사천에서 생육특성과 수량을 평가하였다. 줄기의 털은 콜드그린과 청파는 있었으나, 헤이메이커프러스와 라티고는 없었다. 잎의 모양은 콜드그린은 엽폭이 넓은 장타원형이고, 청파, 헤이메이커프러스, 라티고는 좁은 장타원형이었다. 꽃색은 콜드그린은 자주색이고 청파는 보라색이었다. 내한성은 성주에서 콜드그린, 청파, 라티고가 헤이메이커프러스 보다 높았으며 사천에서는 차이가 적었다. 개화기는 콜드그린과 헤이메이커프러스가 조생종으로 유사했고 중만생종인 청파는 라티고 보다 다소 빨랐다. 성주에서 건물수량은 콜드그린이 다른 품종 보다 높았으며 청파와 헤이메이커프러스는 라티고 보다 높았다(P<0.05). 2005년 사천에서는 콜드그린과 헤이메이커프러스는 다른 품종보다 높았으며, 청파는 라티고 보다 높았다(P<0.05). 베치의 조단백질 함량은 높고 ADF의 함량은 낮았다. The objective of this research was to develop a high yielding, early and medium-late flowering new hairy vetch(Vicia villosa Roth) varieties derived from an accession in Korea. Most vigorous early and medium-late flowering hairy vetch lines were selected and crossed by open pollination and their seeds were bulked and plants were reselected at Seongju in the Keongbuk and at Sacheon in the Keongnam. A performance trial was conducted to evaluate agronomic characteristics, forage quality and dry matter(DM) yield of new hairy vetch early-maturing 'Cold green' and medium-late maturing variety 'Cheong pa' at Seongju and Sacheon. 'Cold green' and 'Cheong pa' are hair but 'Haymaker plus' and 'Latigo' are nearly hairless. 'Cold green' has purple flowers while 'Cheong pa' has violet. The cold tolerance of 'Cold green,' 'Cheong pa' and 'Latigo' was higher than 'Haymaker plus' at Seong-ju, Keongbuk province, in inland region but there were a little differences at Sacheon, Keongnam province in southern coast region. Fifty percent-flowering dates of 'Cold green' and 'Haymaker plus' had earlier than others and 'Cheong pa' was earlier than 'Latigo'. The DM yield of 'Cold green' was higher than that of others, but 'Cheong pa' and 'Haymaker plus' had higher than 'Latigo' at Seong-ju(P<0.05). In Sacheon, The DM yield of 'Cold green' and 'Haymaker plus' was higher than others and 'Cheong pa' had higher than 'Latigo'.

Palm prints have been used for personal identification because they are unique to each individual. Palm prints have also been used for diagnosing genetic disorders and for revealing physical anthropological characteristics, due to their specific appearance characteristic of genetic factors and nationality. Therefore, several analytical methods of palm prints have been developed and applied for the purpose described. However, in the previous reports, the analytical methods of palm prints and the numbers of subjects were insufficient to find Standard values for Korean palm prints. In this study, in order to determine the Standard value for Korean palm prints, we examined palm prints of 3216 Korean adults (2095 males and 1121 females), analyzed the data according to sex and side of hand, and compared with those of foreigners. The results are s follows: 1) The incidence of 7, 9, and 11 of D was 41.8%, 33.5%, and 20.4%, respectively. Comparing the incidences 017, 9, and 11 of D in Koreans with those of foreigners, the Korean belong to the Asians including the Japanese, the Chinese, and the Philippine, however, the Korean was doser to the Blacks and distant from the Whites than the other Asians. 2) The palm prints were classified into the open type in which B terminates at the ulnar border of hand, and the dosed type in which B does not. Open type, 7-5-5 (male 37.6%, female 39.5%) and 9-7-5 (male 23.9%, female 25.5%), was more frequent in female than in male, while dosed type, 11-9-7 (male 9.8%, female 9.1%), was more frequent in male than in female. Also, open type, 7-5-5 (right 28.9%, left 47.6%), was more frequent in left hand than in right hand, while dosed type, 11-9-7 (right 17.1%, left 2.1%), was more frequent in right hand than in left hand. Consequently, open type was more frequent in the weak hand, whereas dosed type was more frequent in strong hand. 3) Because a-b (39.2) and c-d (35.0) were more numerous than b-c (27.8), distance between a and b and between c and d were longer than that between c and d. The long distance of a, b and c, d could be resulted by wide moving range of second finger and fifth finger, respectively. Also, there was a tendency that the palmar ridge counts of right hand was more numerous than those of left hand, which could be resulted by wide moving range of right fingers in the right-handed persons who were more frequent than the left-handed persons. 4) O, in which there was no triradius, and X, in which dermal ridge from a triradius was blocked and terminated at the other dermal ridge, were frequent in C (O 7.8%, × 7.2%) than in D (O 0.1%, × 0.1%) or in B (O 0.4%, X 1.2%). The frequency of 0 and X in C was thought to be related with the location of ein the narrow space between d and b. The narrow space between d and b was known because c-d and b-c was less numerous than a-b. 5) The distances between adjacent triradii were longer in male than in female, however, the palmar ridge counts for a-b, b-c, and c-d were less numerous in male than in female. Consequently, dermal ridges were thought to be thicker in male than in female. The Standard values of Korean palm prints obtained from this study are expected to be used for both diagnosing genetic disorders and for revealing physical anthropological characteristics in Korea. Further studies to clarify the relationship between the palm prints and the power of hand as well as the moving range of fingers are in need.

This is a retrospective study on the transoral approach to open reduction of the Mandibular fractures. Our study was based on a series of 64 patients with mandibular fractures among 99 patients of facial bone fractures who had been treated by transoral approach with or without extraoral approach at Department of Oral and Maxillofacial Surgery, Yonsei Medical Center, Yonsei University from January 1981 to October 1988. We studied favorite sites of open reduction, fixation methods, results and prognosis related to transoral approaches of Mandibular fractures, and which compared with extraoral approaches. The results obtained are as follows : 1. The transoral open reduction was used more frequently in Mandibular fractures(64.6%) than Midfacial bone fractures(35.4%). Among 64 patients of mandibular fractures, 47 patients(73.4%) were treated only by transoral approach and others(26.6%) were treated by both trans and extraoral approach. Among 92 sites of mandibular fractures 75 sites(81.5%) were treated by transoral approach and 17(18.5%) were treated by extraoral approach. 2. The most favorite site for transoral approach compared with extraoral approach was symphysis(100%), and Angle(62.5%) was next in order of frequency on Mandibular fractures. 3. Direct Interosseous Wiring(DIW) was most commonly used for fixation(64.6%) and Miniplate osteosynthesis was used next in 28.1%. 4. Simple(39.1%) and Compound(52.2%) fractures were frequently indicated for transoral approach, however comminuted fractures were rarely indicated. 5. The direction of fracture lines on Angle of the mandible did not influence to determine whether transoral approach should be selected or not. However this area seemed to be more difficult to reduce exactly by transoral procedure than other areas because simultaneous superior and inferior fixation was applied predominantly on this area. 6. The success rate of reduction and fixation analyzed from us was more excellent in Direct Interosseous Wiring(29/53=54.7%) than in Rigid Internal Fixation(9/29=31.0%). But it might be depended upon various factors as like as sugeon's skill. 7. The postoperative complication due to transoral open reduction of mandible was not high(12.0%) and this rate was similar with other published reports.

Many bovine genetic diseases are currently unidentified in Korea because of the relatively low monitoring systems in the livestock farms. The molecular detection system using PCR-RFLP of two genetic diseases, namely Band 3 (Erythrocyte Membrane Protein Band Ⅲ) and CHS (Chediak-Higashi Syndrome), have been identified in Japan and used for screening large number of cattle whether each individual has the genetic disease or not. Using the 22 unrelated Korean cattle (Hanwoo) individuals, molecular detection system based on PCR-RFLP have been investigated, which can be distinguishable carriers for the genetic diseases. Even though we could not found the causative mutations for two genetic diseases, the PCR-RFLP techniques used in this study are very valuable for the screening the genetics diseases in Korean cattle, especially for the proven or candidate bulls.

The purpose of this study was to evaluate the relationship between osteoporosis and periodontal condition in postmenopausal women. Twenty-eight patients who have been treated at Chonnam nationa university hospital with osteoporosis(osteoporotic group, mean age 62.2±6.6) and 21 normal postmenopausal women with periodontitis(control group, mean age 60.4±3.7) were examined. Bone mineral density(BMD) of lumbar spine(L2-L4) was measured by dual energy X-ray absorptiomemtry(DEXA). Percentage to peaked bone mass in osteoporotic group was 70.9% which had lower BMD than in control group(p<0.05). The number of present teeth were 23.6 in osteoporotic group and 23.1 in control group. Percentage of bleeding on probing was 41% in osteoporotic group and 37% in control group. probing depth and attachment level were shown 3.18 mm, 3.63 mm in osteoporotic group and 2.85 mm, 3.11 mm in control group, respectively. probing depth and attachment level were significant greater in osteoporotic group than in control group(p<0.05). The significant negative correlation was found between BMD level and periodontal attachment level(p<0.001, γ=-0.56). These results suggest that osteoporosis may be associated with periodontal breakdown.

This paper is concerned with High Frequency, High Voltage Generator for X-ray using zerovoltage soft-switching PWM DC-DC power converter by resonant method, which makes the most of the parastic IBC parameters of high-voltage transformer link, for diagonostic X-ray power generator. The converter circuit basically utilizes phase-shift pulse width modulated series resonant full-bridge PWM DC-DC high-power converter operating at a constant frequency;25kHz. The high-frequency switching operation of the inverter has some effective advantages with consist in the physical reduction in size and weight and lowered acoustic noise. The converter output regulation is digitally controlled using DSP(Digital Signal Processor) for obtaining a fast rising time and adjust output voltage within a wide load range. This converter characteristics are evaluated in terms of computer-aided analytical and experimental results.

We have fabricated various solar cells, such as p-n junction p-AlGaAs/p-GaAs/n-GaAs heteroface and p-GaAs/i-(InGaAs/GaAs)/n-GaAs multi quantum well structure solar cells, which art grown by low-pressure metalorganic chemical vapor deposition(MOCVD). The electrical and structural properities of epitaxial layers have been characterized by Van der Pauw Hall measurement and DCXD(double crystal X-ray diffractometry) measurement. Current - voltage (I-V) characteristics have been investigated by curve trace and light source was tungsten-halogen lamp (34.992 mW/cm^(2)). The conversion efficiency of AlGaAs/GaAs p-p-n heteroface solar cell (V_(∝) : 0.62 V, I : 3.2㎃, efficiency : 10.1%) is greater than the simple p-n junction solar cell (V_(∝) : 0.59 V, I : 2.9 mA, efficiency : 9.1%). In the multi quantum well structure solar cell(p-GaAs/i-(InGaAs/GaAs)/n-GaAs), short circuit current (5.5mA) increased a little.

The electrolyte solid films for the rechargeable Li-ion thin film batteries were deposited by RF sputtering method using a Li3PO4 sputter target and increasing RF power under a flowing N2O or N2 atmosphere. The chemical bond structures were spectroscopically analyzed by using FTIR (fouler transform infrared spectroscopy) and XPS (x-ray photoelectron spectroscopy). The FTIR absorption spectra of the films exhibited two principal stretching bands, one associated with the PO3 stretching mode and the other with the P-O-P stretch mode. The XPS N1s peaks located at 398.2∼404.5 eV indicated that the N bond structure in the film consisted of chemical bonds, such as nitride bonded to P and/or Li atoms. To be influenced by the nitrogen, the ionic conductivity of the films deposited Using N2 has to be 10 orders of magnitude higher than that of the films deposited Using N2O.
