Liquid metals continue to be of great interest as nuclear reactor coolants. One fundamental quantity required for design of such cooling systems is the heat transfer coefficietnt. Despite on-going interest and intensive research activities, the prediction of liquid metal heat transfer coefficients is still not satisfactory. Experimental results are not in good agreement with theoretical ones. This report describes some heat transfer coefficients observed under special circumstances. In particular, observations were made on a "figure-of-eight" system containing flowing sodium. The heat exchange was between a tube and an annulus. The tube and annulus exchangers were made in two different sizes. The sodium temperature range from inlet to outlet was large. In exchanger A the wall thermal resistance was 25% of the total and in exchanger B it was 45% of the total. The observed overall coefficient should be compared to the predicted overall coefficient. The length of run numbers showed the great stability of observed heat transfer coefficients over long times.

The studies was conducted to establish the indoor overwintering methods for productive honeybee colonies in the wintering chamber which provides satisfactory inside temperature ranging 2∼9。C and ventilation for the wintering honeybee colonies in Korea. Mortality of the indoor wintered honeybee colonies was 6.3∼7.1% during the winter season of 1997-1998 and 5∼10% during the winter season 1998∼1999. The decreased rates of colony weights during the wintering season were 10.6∼10.7% in the strong colonies and 10.2∼11.7% in the weak colonies. The increased rates of colony population overwintered in the chamber were 136.1∼142.3% in the strong colonies and 128∼136.5% in the weak colonies.

A range of indicators is available to assess renal dysfunction in lead exposure. This study was undertaken to find out which indicators were most valuable as markers of renal dysfunction. We selected 75 male workers from the secondary lead smelter, plastic stabilizer and radiator manufacturing industries (the "exposed" group) and 64 male office workers (the "control" group). Blood lead; blood zinc protoporphyrin; urine lead; urine coproporphyrin; δ-aminolevulinic acid dehydratase activity; and urine δ-aminolevulinic acid were chosen as indicators of lead exposure. Blood urea nitrogen; serum creatinine; serum uric acid; N-acetyl-β-D-glucosaminidase; urine albumin; urine α₁-microglobulin; and urine β₂-microglobulin were used as indicators of renal dysfunction. Urine α₁-microglobulin level was significantly associated with the lead exposre level. Blood urea nitrogen, urine N-acetyl-β-D-glucosaminidase and urine α₁-microglobulin levels were highly correlated with indicators of lead exposure. Urine α₁-microglobulin had the highest correlation with other indicators of renal function. In addition, the proportion of subjects with high urine α₁-microglobulin levels showed a gradient with lead exposure. Conclusively, blood urea nitrogen, urine N-acetyl-β-D-glucosaminidase and urine α₁-microglobulin are useful indicators, but urine α₁-microglobulin is the early and the most valuable indicator of renal dysfunction related to lead exposure.

英國物品賣買法과 韓國民·商法上의 比較硏究 : 危險負擔을 中心으로 Centered on Risk Bearing

李東烈,沈載淑 호남대학교 1998 호남대학교 학술논문집 Vol.19 No.1

In Britain, it adopts ownership as a principle that an owner has the risk of goods and the risk is transferred when ownership is handed over. Sales of goods Act, In Britain precribes that, if the persons concerned have no any contact, a seller has the charge of the risk until a buyer takes ownership. Whatever a transfer, furthemore, the buyer has the risk as he(she) has ownership. That is to say, the risk of goods, in principle, belongs to an owner and it is moved when the ownership is assigned. Judicial precedent in Britain, on the other hand, did not admit the principle, 'Owner takes the charge of risk'. as an absolute rule, and granted an exceptin that the risk may be changed by stated or intended indication of the persons concerned. In other words, the persons concerned can divide the transfer of ownership and the transfer of risk by compromise. There are only two provisions, Article 537 and 538, regulated the risk bearing in civil law in Korea. In a bilateral contract, both could take the risk because two debts oppose to each. One of the debts, in modern contract, plays a leadinf part in the contract, thr other has a sense of cost. also, only the former, particularly goods, keeps the worry of paying incapability. The risk of two debts, therefore, are called the risk of goods and the risk of cost respectively. By Article 188 in civil law, the risk is transferred as goods is shifted. Accordingly, this corresponds to German civil law.

The export of Korea, not with standing its unfavorable economic conditions including the shortage of natural resources and the narrowness of its domestic markets, has made great contribution to the higher degree of economic development of this country by the strength of the government's strong export-oriented importance of export in this country cannot be too much emphasized as export is closely connected with production, employment, income and various effects of import induction and contribution to the economic growth. Korea's export, however, has faced with many difficulties since the 2nd Oil Shock in 1979 because of the deterioration of expert conditions such as the continuous depression of the world economy, the intensification of stagflation and the reinforcement of the protective policy by developed countries. In particular, in the structure of the export commodities, the foreign exchange earning rate is going down as the weight has been gradually put on the heavy industries which have smaller effects of income induction and larger effects of import induction rather than light industries. And in the structure of export market the emphasis of heavy industries has caused an unfavorable trade balance even though the phenomena of regional overemphasis on particular markets have been much improved. For the purpose of solving these structural problems and of improving export of korea, the following opinions are suggested in this paper: 1. multilateral efforts to build up the international competitive power, 2. establishment of exporting order, 3. diversification of export markets and strengthening of marketing activities, 4. efforts to increase continuous export of light industry goods, 5. expansion of industrial base to raise the foreign exchange earning rate.

Due to the successful policy of economic development by export promotion since 1960's, our conutry has attained the contiunal high economic development and become one of newly industrializing conutries. However, it must be pointed out that one of major factors which play a great part in the courseof this rapid economic development is the introduction of foreign capital which has greatly contributed to the capital forming in our conutry. As the Result of it, it is at a heavy burden on our country that there are difficulties such as the presure of the balance of international payment, because the size of foreign debt at the end of 1986 is over 44.5 billion dollars, which is grater than the approriate proportion of yearly repayment of the amount with interest added against GNP. Thus, government is inviting the investment of foreigners positively for the purpose of supplying fo necessary funds without the direct buden resulted from the repayment of the amount with interest added. Recently, the step government takes for a step by step liberartion of capital according to the nation economic requirement and the trend of worldwide open-economic system are as follow : firstly, the open policy of foreign investment by the entire reorganization of the system of introduction of foreign capital, secondly, the simplification of the procedure of approval, and thirdly, the supply of incentive to further foreign investment, etc. In conclusion, according to these policies of government, foreign investment will be made more actively in our economy.

In this study, we demonstrated passive single-mode fiber depolarizer for WDM optical communications. We simulated that birefringence of fiber-ring is acted as a depolarizer and found the proper parameters. The minimum degree of polarization of -20dB was achieved. Application of this depolarizer includes not only fiber optic sensors but also WDM optical communications with very narrow spectral width.
