1976年 以來 우리나라에서 漁獲量이 急增하고 있는 정어리를 보다 效率的으로 食用化하기 위한 方法을 檢討하기 위하여 粉末燻乾정어리의 加工 및 貯藏에 관한 實驗을 하였다. 製品은 水分이 11.7%, 脂肪이 22.9%, 蛋白質은 61.7%였고, 原料 fillet에 대한 收率은 16.8%였으며, 담백한 맛과 燻乾品特有의 香氣가 있었다. 그리고 製品은 탄산가스 중에 貯藏하면 貯藏 중 酸化酸量의 變化가 거의 없고 品質을 安全하게 保藏할 수 있다는 結論을 얻었다. Since 1976 the catches of sardine have been increased rapidly in Korea. A processing method of smoked sardine meat powder and its quality changes during storage were studied. The fillets of raw sardine meat were boiled at 98℃ for 1 hour in a wire basket. After cooling at room temperature, the boiled fillets which small bones were removed were smoked at 60-70℃ for 8 hours. The second smoking was carried out under same conditions after 24 hours. The products were cleaned with brush and then powdered. The contents of moisture, lipid and protein were 11.7%, 22.9% and 61.7%, respectively. The yield of the product to the weight of raw fillet was 16.8%. According to the results of panel test, the product was well accepted having meaty taste and characteristic smoky flavor. The amount of oxidized acid in the product increased only a little during the storage in carbon dioxide gas.

李應昊,金洙賢 釜山水産大學校 1975 釜山水産大學 硏究報告 Vol.14 No.2

굴비 製造中의 一般成分, 아미노態窒素, 總窒素 및 核酸關聯物質의 變化를 實驗하여 다음과 같은 結果를 얻었다. 1. 原料 참조기에는 IMP와 inosine含量이 월등하게 많았고, ATP, ADP, AMP및 hypoxanthine은 적었다. 2. 마른간 工程中, 原料 참조기중에 많았던 IMP(13.7 μmloe/g, dry base) 는 약 1/9로 inosine (12.9μmole/g, dry base)은 1/3로 減小하였고, 한편 hypoxanthine은 5.7培로 增加하여 19.2μmole/g, dry base였다. ATP, ADP 및 AMP는 큰 變化가 없었다. 마른간 한 後 굴비를 製造하기 위한 乾燥工程에는 鹽藏直後에 많았던 hypoxanthine은 約 1/2로 減小하여 10.2μmole/g. dry base였다. 굴비 중에는 hypoxanthine 含量이 가장 많고, ATP, ADP, AMP, IMP��inosine은 量이 아주 적었다. 3. 굴비 製造中 脫水는 主로 鹽藏工程中에 일어 났으며, 아미노態窒素는 原料 참조기에 乾物重量基準으로 136㎎%이던 것이 鹽藏直後에 298㎎%로서 鹽藏工程中 2.2倍 增加하였고, 굴비 第品은 354mg%로서 鹽藏後 굴비를 製造하기위한 乾燥工程中에 다시 增加하며 原料에 비하여 2.6倍 增加하였다. 4. 굴비의 獨特한 맛에 核酸關聯物質은 큰 구실을 하지 않는다고 보아지며, 아미노態窒素가 굴비 製造工程中 월등히 增加하는 것으로 보아 呈味性 아미노산 및 肉組織이 큰 구실을 할 것으로 보아진다. "Gulbi", salted and dried yellow corvenia, is one of nation-widely consuming fish foods in this country. In this paper, the degradation of nucleotides and their related compounds in yellow corvenia during "Gulbi" processing was studied. The nucleotides and their related compounds were extracted with cold perchloric acid and the amounts were determined by anion exchange column chromatography. In raw yellow corvenia, the results showed that IMP and inosine were dominant and the content of the former was 42.4% and the latter was 39.9% of total nucleotides and their related compounds, and hypoxanthine was 10.4% while the content of ATP, ADP and AMP were low. The IMP and inosine tended to degrade rapidly and hypoxanthine increased remarkably during cry salting for 14 days. After salting and drying, hypoxanthine remained more than the other nucleotides and their related compounds, and ATP, ADP and AMP hardly changed. After "Gulbi" processed, the content of hypoxanthine was the highest whereas ATP, ADP, AMP, IMP and inosine were lower. Free amino nitrogen increased to 2.6 times of that in raw muscle during "Gulbi" processing. As a conclusion, it is presumed the characteristic flavor of "Gulbi" is not attributed to the nucleotides and their related compounds but free amino acid and texture of muscle.

The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Gyeongbuk area. Also, we collected soils from several area in Gyeongbuk, and determined heavy metal concentration of soils by ICP. We compared with herbal medicines in products of Gyeongbuk and their soils. The average levels of heavy metal of herbal medicines in Gyeongbuk area are as follows : Mercury is 0.037㎎/㎏, Chromium is 0.093 ㎎/㎏, Nickel is 0.108㎎/㎏, Copper is 0.475㎎/㎏, Zinc is 3.14㎎/㎏, Manganese is 1.52㎎/㎏, Iron is 7.83㎎/ ㎏, and Cadmium, Lead and Arsenic is not detected. It was very lower in concentrations than those of average Korea area. For the heavy metals contents of Gyeongbuk area, in Gong Jung Ri, represented the higher level, it may be due to a near the road. The Cd contents in soil was not a wide difference. For the As and Pb contents in soil, Song Sa Ri (Bupleuri Radix) represented the higher level(0.68㎎/㎏, 1523㎎/㎏). Correlation coefficients of heavy metal contents in cultured herbal medicines and their soils did not give reproducible results. But the degree of correlation between a few heavy metal contents of Dioscoreae Rhizoma and their soil showed the good transfer from the soil.

The purpose of this study was to evaluate the actual state of Koreans' behavior about the use of oral hygiene devices and to collect the baseline data for developing appropriate educational objectives to improve dental health. Questionnaires were used to personally interview 1,685 residents in Korea. The obtained results were as fallows; 1. Average head size of toothbrushes was 23.2㎜ in children, 28.2㎜ im adults. 2. The averagep percent of using dentifrice containing fluoride at home was 66.7% in children, 71.4% in adults. 3. The average percent of using orthodontic toothbrushes was 50.5% in orthodontic patients, and the average percent of using interdental burshes was only 16.9% in orthodontic patients. 4. The average percent of using dental floss was 22.3% in periodontic patients, and the average percent of using interdental brushes was 16.5% in periodonitc patients. 5. The patients usually use oral hygiene devices by means of dentals' suggestions and commercial advertisement. 6. Generally few people use auxiliary oral hygiene devices. To improve the oral health starus effectively, more improved and correct informations and materials should be provide to dentists, dental hygienists and patients.

콩에서 경장과 연관된 DNA 표지인자를 개발하여 품종육성에 활용함으로서 육종효율 증진에 기여하고자 수행하였다. 본 시험은 육성된 큰올콩과 신팔달콩의 RIL 계통 및 SSR marker를 이용하여 유전자지도를 작성하고, 이를 바탕으로 경장과 관련된 양적형질 유전자좌(QTt)를 탐색하였다. 시험재료로 이용된 큰올콩과 신팔달콩은 경장이 각각 30.57 cm와 49.75 cm로 매우 큰 차이를 보였다. 경장과 연관된 QTL은 개별마커들과의 분산분석 결과, 연관군 F, J, N 및 O에서 전체변이의 37.83%를 설명할 수 있는 4개의 QTL을 탐색하였다. 특히, 연관군 J와 O에서 각각 14.25%와 10.68%를 설명할 수 있는 주요 QTL을 확인하였다. 따라서 경장 관련 QTL중 연관군 J와 O에서 확인된 주요 QTL은 품종 육성과정에서 경장 관련 선발 마커로서 활용가치가 높은 것으로 판단된다. Identification of individual quantitative trait loci (QTL) is a prerequisite to application of marker-assisted selection for stern length. Two simple sequence repeat (SSR)-based linkage maps were constructed from recombination inbred line populations between cross of Keunolkong and Shinpaldalkong. Two parents used differed greatly in stem length, which were 30.57 cm and 49.75 cm in Keunolkong and Shinpaldalkong, respectively. Using the constructed maps, regression analysis and interval mapping were performed to identify QTLs conferring stem length. Four QTLs for stem length on linkage groups (LG) F, J, N and O were identified in the Keunolkong ${\times}$ Shinpaldalkong population and they totally explained 37.83% of variation for stem length. In the population, two major QTLs on LG J and O conditioning 14.25% and 10.68% of the phenotypic variation in stem length were determined and two QTLs with minor effect were detected on LG F and N. Identification of QTLs for stem length and mapping individual locus should facilitate to describe genetic mechanisms for stem length in different population. SSR markers tightly linked to QTLs for stem length allow to accelerate the elimination of deleterious genes and selection for desirable recombinants at early stage in crop breeding programs.

A study of continuous postoperative regional analgesia by nerve sheath block for limb amputation is presented. The authors reviewed 65 patients with amputation at the level proximal to the wrist or ankle. 15 patients of which were managed with continuous postoperative regional analgesia (CPRA) by nerve sheath block. At the time of exposure of nerve trunk during amputation, a catheter was introduced directy into the transected nerve sheath through a seperated stab wound, then infuse 0.5% bupivacaine 5ml prior to wound closure and postoperatively at the rate of 2 ml/4~6 hours for 3~4 days. The results were as follows : 1) Effective amputation stump analgesia was obtained, significantly reducing the need for narcotic analgesics. 2) 46 (70%) patients experienced Phantom phenomena and 30 (46%) patients experienced Phantom pain, a less frequently in CPRA group. 3) Phantom pain was more commonly observed in patients with rnore severe preamputation pain. 4) There were no significant relationships between the occurence of Phantom pain and the age of amputee or the level of amputation. We concluded that continuous postoperative regional analgesia by nerve sheath block significantly reduced the narcotic requirements in patients with ampotation surgeries.
