This study tests the difference of pricing of foreign currency risks between the Korean stock market and the New York stock market. Test results show that foreign currency risk is priced in the Korean stock market after foreign currency crisis. However, the foreign currency risk is not priced in the New York stock market during the same periods. These results means that the foreign currency risk is a systematic risk in Korean stock market, but the foreign currency risk is an unsystematic risk in New York stock market. This study result suggests that the Korean company exposed in foreign currency risk could increase its value by listing in the New York Stock Exchange.

Does free transplanted autologous cartilage grow? Until now many autors have published different results about the growth potential of cartilage. Some authors have produced in their study that transplanted cartilages were able to grow, but others showed contradicting results. In this study, authors obtained cartilages from young rabbits'ear, 10 by 10mm in size and divided them into two groups ; the first group was cartilages with perichondrium and the second group was cartilages stripped perichondrium. We transplanted both groups of cartilages in the posterior nuchal area of rabbits. Then numbers of specimens of each group were evaluated and compared for assessment of cartilage growth. After observaton for six months, we took the cartilages from the posterior nuchal area and examined the surface area, the thickness, and the weight and finally confirmed the growth potential of the cartilage by histologic study. The results are as follows : 1, The surface area, the thickness, and the width of the transplanted cartilages were increased significantly in gross specimens and their measured values were statistically significant and cartilages with perichondrium showed more growth than cartilages stripped perichondrium 2. In histologic studies, we observed increased surface activities with numerous proliferatng cells and found no abnormal features compared with normal cartilages. Cartilages with pericondrium were thicker than cartilages with stripped perichondrium

For the Tailor Welded Blank sheet used for automobile body panel, the characteristics of fatigue strength and crack propagation behavior were studied. The thickness of specimen was joined to be same (0.9mm+0.9mm) and different (0.9mm+2.0mm). As a base test, mechanical properties around weld zone were examined. The results indicated that there were no significant decreases in mechanical properties, but hardness around weld bead was 2.3 times greater than base material. The fatigue strength was the highest when the loading direction was parallel to the welding direction, which was about 85% of tensile strength of base metal. It was decreased by 8.5% when the thickness of specimen and base metal was different, and it was increased by 25% when pre-strain was applied. The crack propagation rate was noticeably decreased around weld line and rapidly increased as it passed through weld line. Reviewing the shape of the crack propagation, crack width around weld line was wide around the weld zone due to retardation of crack growth, but it became narrow passing weld line due to decreased toughness.

The objective of this study was to examine the growth and regeneration patterns of hardwood saplings after thinning of Pinus rigida planted at Mt Worak After thinning of P. rigida, r-selection species such as Rubus crataegifolius B, Lespedeza maximowiczii C, Aralia elata var canescen N., Rubus oldham M and Quercus spp were mainly appeared Regarding to numbers of young trees appearance, Q. mongolica F, Q acutissima C, Q. serrata T and Q variabilis B1 were appeared respectively At the study area after thinning, Q. mongolica F was regenerated by sprouts on the other hands, Q. acutissima C, Q serrata T and Q. variabilis B1 were regenerated by seedlings. The results of this study indicated that Q mongolica F tended to dominate as a natural regenerated species after thinning of the P. rigida. At the humid area, Q serrala T tended to dominate. While, at the dry area, Q. mongolica F. tended to dominate. In the case of Q. variabilis B1, no significant influence was found due to small number of population.

한국산 감귤 수입 예상국의 수입 검역제도에 관한 연구

김택조,강영길,권오균 濟州大學校 亞熱帶農業硏究所 1995 亞熱帶農業硏究 Vol.12 No.-

수출밀감 생산지와 밀감 수출관련기관에 유용한 정보를 제공하고자 제주산 온주밀감 주요수입국 및 수입가능국의 검역제도를 조사분석한 결과를 요약하면 다음과 같다. 1. 조사대상국의 연간 수입량은 캐나다 61.5천톤, 미국 101.1천톤, 일본 1.2천톤, 홍콩 32.3천톤 정도이었고 1993년 한국산 감귤 수입량은 캐나다 1107톤, 홍콩 6톤, 러시아가 150톤이었다. 2. 캐나다는 병충해 위험도 평가를 실시한 후 한국산 밀감을 식물위생증이나 수입허가서 없이 수입하고 있다. 수입검사 중 캐나다에 분포하는 병해충으로서 감염정도가 심하지 않은 식물류는 소독처리하고 캐나다에 분포하지 않은 병해충이나 분포하는 병해충이라도 감염이 심한 경우 폐기 (반송)된다. 한국산 밀감의 경우 부패과를 제외하고는 검역상 문제가 되지 않고 있다. 3. 미국은 수입허가제를 채택하고 있으며 한국산 밀감은 궤양병, 흑반병, 화살깍지벌레의 미국내 유입을 막기위하여 수입이 금지되고 있으나 궤양병 무병 생산단지 및 완충지대 설정, 과실의 예방적 소독처리, 박테리아제 테스트 실시, 선과 후 안전조치등을 조건으로 미국내 수입이 한미간 합의 되었다. 과실의 채소류의 반입항에서 수입물량의 약 2%의 임의 표본 추출하여 검사하며, 미국에 분포하는 병해충만이 검출되는 경우에는 수입이 가능한 반면 검역대상 병해충이 발견될 때 소독방법이 있을 경우에는 소독하고 소독방법이 없을 경우에는 폐기 또는 수입이 거부된다. 4. 일본은 14종의 금지병해충의 기주식물 및 식물성 생산물의 수입을 금지하고 있으나 한국산은 수입금지품에 해당되는 식물이 없다. 금지병해충 (14종)과 특정 중요병해충 (42종)이 부착된 식물중 효과적인 소독방법이 확립되어 있지 않은 과실은 폐기되고 소독가능 병해충이 발견된 과실류는 소독되거나 선별된다. 5. 홍콩에서의 수입 비제한 품목인 과실 및 채소류는 식물위생증이나 수입허가서 없이 수입되며 수입검사중 병해충이 발견되면 소독처리된다. 6. 러시아에서는 수입비제한 품목을 제외하고는 식물 및 식물성 산물의 수입시 식물위생증과 수입허가서가 요구되며 허가항을 통하여 수입되어져야 한다. 7. 감귤류가 재배되지 않아 수입검역이 까다롭지 않은 캐나다, 홍콩, 러시아의 동부에 한국산 밀감 수출 증대를 도모하는 것이 바람직하다. This study was conducted to obtain knowledge of import quarantine system in Canada, the U.S.A., Japan, Hongkong and Russia, which may facilitate export Korean mandarins to these countries. The results are summarized as follows : 1. Canada, the U.S.A., Japan, Hongkong annually import about 61,500, 101,100, 1,200 and 32,300 tons. respectively, of such citrus fruits as mandarins, tangerines and clementines. In 1993, 1,107 tons of Korean mandarins were imported into Canada, 6 tones into Hongkong and 150 tones into Russia. 2. After pest risk on Korea mandarins for Canada was assessed, the mandarins have been imported into Canada without phytosanitary certificate and import permit. When either diseases and/or pests which have occurred in Canada are found or they are not severe during import inspection, disinfection is ordered. When either diseases and/or pests which have never occurred in the country are found or they are severe, the importer is ordered to destroy or reship the shipment. In Canada, import quarantine for Korean mandarins has been smooth except the rotten fruits have been found. 3. The import of Korean mandarins into the U.S.A. is prohibited to prevent citrus caker, phoma rot and arrowhead scale from being introduced into the U.S.A. However, it has been agreed between Korea and the U.S.A. that there can be imports into the U.S.A. of mandarins from Chejudo based on implementation of certain procedures. At the ports of entry, inspections are conducted by sampling about 2% of the imported amount of fruits and vegetabls. When injurious diseases and/or pests are found, disinfection is ordered. When there is no methods of disinfection which can completely kill the diseases and/or pests, the importer is ordered to destroy or reship the shipment. 4. Prohibited are host plants and plant products of 14 kinds of diseases and pests that have never occurred in Japan. In import inspection, when diseases and/or pests are found, disinfection is ordered. When there is no methods of disinfection which can completely kill the diseases and/or pests. the importer is ordered to destroy or reship the shipment. 5. Fresh fruits and vegetable can be imported into Hongkong without phytosanitary certificate and import permit. When diseases and/or pests are found during import inspection, disinfection is ordered. 6. Phytosanitary certificate permit are required in Russia for import of plants and plant products from foreign countries. The port of entry is designated by the quarantine authorities. It seems to be desirable to try hard to increase export amount of Korean mandarins to Canada, eastern Russia and Hongkong which do not raise citrus fruits and are not strict for import quarantine of citrus fruits.

양념에 Leu. mesenteroides, Lac plantarum의 젖산균과 멸치액젓 첨가가 김치 양념의 대장균군 제어, 속성촉진여부 및 관능적 특성에 미치는 영향을 조사하였다. Leu. mesenteroides과 젓갈을 첨가한 경우 초기 숙성이 촉진되나 후기 산패는 완만하였으며 Lac. plantarum의 첨가시에는 초기 숙성에는 큰 차이가 없고 후기 산패가 현저하게 진행되었다. 대장균군은 산도 0.80% 이상에서 사멸되었는데 leu. mesenteroides의 경우가 숙성이 촉진되어 보다 신속히 사멸시켰다. 총균수와 젖산균수는 초기에 starter 첨가구는 10^6CFU/mL 정도인데 반해서 starter를 첨가하지 않은 않은 처리구에서 총균수는 10^6CFU/mL , 젖산균수가 10^4CFU/mL 이었고 숙성 후에는 첨가균이 높은 수준을 유지하였다. 하지만 대체적으로 스타터의 첨가가 숙성 및 대장균에 크게 영향을 주지 못하는 경향으로 동일하게 나왔다. 관능적 특성에서는 Leu. mesenteroides 첨가구가 Lac. plantarum의 경우보다 우수하였다. 한편, 시판 겉절이 김치는 산도가 0.09~0.18%, ph 5.46~5.89, 총균수 2.2×10^6~3.1×10^7CFU/mL, 젖산균수는 2.1×10^4~6.6×10^5CFU/mL, 대장균수는 1.8×10^4~7.1×10^5CFU/mL, 염분 1.89%~2.51%으로 스타터 첨가 겉절이에 비해 ph와 염도를 제외한 품질 특성에서 전반적으로 낮은 값을 나타냈다. This study was performed in order to investigate the effect of Leuconostoc mesenteroides, Lactobacillus plantarum and salt fermented anchovy extracts on Kimchi sauce. The sauce was fermented more rapidly by addition of Leu. mesenteroids or salt fermented anchovy extracts on the early fermentation stage than the control, but it was fermented slowly on the late fermentation stage. When L. plantarum was added to the Kimchi on the early fermentation stage, the acidity of Kimchi didn't show a significant difference from the control, but acidity was remarkably increased on the late stage. Coliform group was disappeared when acidity of sauce was higher than 0.8% during fermentation. It was controlled by Leu. mesenteroides but not by L. plantarum. Total count and lactic acid bacterial count of the sauces with starter were 6.30×10^6~1.0×10^7 CFU/mL and 1.04~2.04×10^6 CFU/mL, respectively, but those of the control sauce were 10^6 CFU/mL and 10^4 CFU/mL, respectively. Those count of the sauce with starter were higher than those of the control sauce on the later stage of fermentation. Organoleptic quality of the sauce with Leu. mesenteroides was superior to that with L. plantarum.

Current industrial infrastructure has some drawbacks such that the effort for the efficiency of the facilities, most of which are imported, increase the cost of manufacturing. the special types of valves have been imported since the performance and the functional requirements are satisfied by the home products. Actually, the local products of the valve can be used only 1,000m Aq of lower pressure. On this paper, we develop the high pressure divert valve, which can be born the pressure of 3,000mm Aq. This development can contribute to the reduction of the cost and the increase of export.

재배종과 야생종의 인공교잡 분리세대에서 주요형질들의 변이와 유전력을 조사하여 야생종을 이용한 콩 품종육성의 기초자료를 얻고자 수행한 결과를 요약하면 다음과 같다. 두 인공교배의 F_2 집단에서 100립중을 제외한 나머지 조사 형질들은 초원분리를 보였다. F_1과 F_2의 평균 개화일수는 양친의 중간정도로 정규 분포를 보였다. 백립중의 F_1 평균은 은하콩, 소백나물콩 두 조합 각각6.5, 5.7g으로 소립종 쪽으로 치우친 정규분포를 보였다. F_2의 평균수량은 양친의 중간정도이었다. F_1의 덩굴성은 두 조합 각각 6.4, 6.6이었으며 F_2 평균은 은하콩 조합이 6.0으로 덩굴성 쪽으로 치우쳐 덩굴성이 부분적인 우성으로 보였으나, 소백나물콩 조합에서는 4.6으로 은하콩과는 다른 결과를 보였다. 경장, 개회일수, 개체당 협수, 수량, 도복, 덩굴성 등은 높은 광의의 유전력을 보였으며 100립중은 협의의 유전력이 은하콩 조합에서 52.3%, 소백나물콩 조합에서 65.6%로 평가되어 초기세대에서의 선발이 가능한 것으로 나타났다. This study was conducted to obtain the information of varietal development using wild soybean through investigation of variation and heredity of major agronomic characters in F_2 generation of interspecific cross between Glycine max and G. soja. In segregating populations of two crosses, all characters observed except 100-seed weight showed transgressive segregation. Days to flowering showed normal distribution; mean days to flowering in F_1 and F_2 was approximately mean of parent. Mean of F_1 for 100-seed weight was 6.2g and 5.7g for Eunhakong/KLG10084 and Sobaegnamulkong/KLG10084, respectively, which were somewhat skewed distribution to small seeded parent. Mean of F_2 was about mean of two parents. Degree of vine was 6.4 and 5.7 in F_1 for two crosses but it was 6.0 in F_2 for Eunhakong/KLG10084, which revealed the degree of vine as partial dominance while 4.6 for Sobasgnamulkong/KLG10084, somewhat different results from the previous cross. Broad-sense heritability(h^2B) for plant height, days to flowering, pods per plant, seed yield, and degree of vine was comparatively high and narrow-sense heritability(h^2N) for 100-seed weight which is the most important character in the development of small seed-size sprout soybean was 52.3% and 65.6% for Eunhakong/KLG10084 and Sobaegnamulkong/KLG10084, respectively, which indicated that selection for the character in early generation was possible.
