An extensive corrosion study was initiated by galvalume steel sheet manufacturing company to clarify the corrosion behavior of zinc and zinc-alloy coated automotive sheet steel in out panel and electrical application. Since the early 1980's the use of zinc and aluminum alloy coated steel for vehicular corrosion protection has increased dractically. This paper describes the evaluation of formability, weldability and painted corrosion performance of galvalume steel sheet. This paper presents an overview of the program and some initial test results on the of weldability, lifetime on the electode tip shape of spot welder and corrosion protection. Galvlume steel sheet improved corrosion performance and spot weldability of galvalume steel has no problem for the variation of welding current. And tip lifetime was changed according to the influence of shape.

As demand for various kinds and small lot products has been increasing, batch annealing has been appreciated for its small restriction for the operation. The cold spot of the coil is very important in the BAF(Batch annealing furnace) annealing process. Because of the annealing cycle time in the BAF, annealing was decided on the cold spot of the coil Development on the mechanical properties of steel sheet for the automobile body panel is very important in the BAF annealing process. Because of the heat treatment method in the BAF, mechanical properties was decided on the heat treatment method of the coil. So, we tested on the development of mechanical properties according to heat treatment method at the annealing furnace using the Ax atmospheric gas and the HNx atmospheric gas. As a result of several investigations. We confirmed the following characteristics mechanical properties was changed under the influence of the annealing cycle and the atmospheric gas. The cold spot of coil was the mid point of the B coil in the Ax atmospheric gas. And, atmospheric gas is very important in the high convection annealing furnaces. And so, we tested the effect, variation of cold spot, for hydrogen contents of atmosphric gas at the annealing furnace. As a result of several investigations. We confirmed the following characteristics after the heating and soaking, the cold spot of coil moved to 1/3 of coil thickness in the HNx atmospheric gas, but the mid point of the coil thickness is the cold spot in the Ax or H2 atmospheric gas. Therefore, the use of hydrogen instead of nitrogen as the protective gas, combined with high convection in batch annealing furnaces, has shown that considerable increases n furnace output and material quality are attaninable. Owing to the low density, high diffusion and reducing character of hydrogen, a better transfer resulting in uniform material temperatures and improved coil surfaces can be achieved.

The present study was performed to analyze the nutrition status related to body weight control and nutritional knowledge. Two groups, lectured and unlectured group for nutritional class in college women, were considered for this investigation. Their average height and weight were 160.5cm, and 51.5kg respectively. The evaluation of this study was carried out by statistical analyses that obtained from the basis of five different models. The result indicated that health status was pretty fair, however, the most of subjects had symptoms such as weariness, stress, and disorder of stomach. In selection of actual body size and ideal body size among the five models for female, which drawn ranges from 20% underweight to 20% overweight, 82.7% of the subjects think their weights are higher than their standard weight. Also 99.3% of the subjects selected the underweight as the their ideal body size. It was appeared that 66% of the subjects had a desire to lose weight, while 14.5% of them wanted to gain weight. Those who think are thinner than standard weight, were more satisfied with their body sizes than those who think they are fatter. Most subjects started to concern their body size through conversations with their friends after entered college. Most nutrients were taken properly, but certain nutrients were insufficient as compared to the RDA. The average intaken calorie(84.7%), iron(87.2%)and ascorbic acid (97.1%) were lower than those of the R.D.A.. The ratio of calorie percentages for corbohyerates vs. protein vs. liquid (from total calories) was 61:24:15. This ratio was properly approached to the recommended calories compositions(based on recommended allowance 5th Ed.). Intaken calories are changed significantly by the degree of perception body size(P<0.05). Knowledge of nutrition was significantly higher for the educated group than uneducated group(P<0.001).

This study was performed to investigate the contamination level of harmful heavy metals in 11 species shellfish collected at the four sampling sites of the western coast in Korea from June to November in 1996. The levels of total lead, cadmium, mercury, copper and zinc were determined and the results were summarized as follows (ppm) : The minimum and maximum values of shellfish, mean value bracketed, were ; Pb : 0.07-7.42(3.09), Cd : 0.015-0.573(0.08), Hg : 0.44-1.93(0.69), Cu : 2.88-112.68(19.46), Zn : 50.79-578.90(124.84). The results show that mean contents of Pb, Cd, and Hg in 11 species shellfish were not yet dangerous levels enough to pose a health problem. But the contents of Pb, Hg, Cu and Zn has a increasing tendency.

The questionaires answered by 248 housewives in Onyang and Chunan were analyzed for the relationship between nutritional knowledge, food habits and the general characteristics of the subjects. The mean score of the nutritional knowledge and food habits were 9.3 out of 14 and 10.5 out of 12 points respectively. Casual relation between food practice and other independent variables(age, socioeconomics, education, etc.) was studied by SPSS path analysis. The subjects' nutritional knowledge was influenced by education and socioeconomics(P<0.01). Higher education and socioeconomics resulted better in knowledge score. In the diet attitude of the housewives, those who had problems of food were 53.2% and had not any problem were 46%. The problems were absent of diet chance (27.4%) and quantitative and qualitative degrees of satisfaction(17.7%).

프랑스 낭만주의 선구자로서의 Jean-Jacques Rousseau 와 자연

김순경 中央大學校 人文科學硏究所 2003 人文學硏究 Vol.35 No.-

18세기 후반부와 19세기 초의 프랑스 문학의 중요한 큰 흐름은 감수성의 진화와 자연관의 변화라 할 수 있다. 자연이라는 대상을 새롭게 맞이하여 시각적으로 재발견하였고 또한 감정에 의해 새롭게 보게 되었던 것이다. 그리하여 자연의 객관적 묘사 대신에 감성이 개입되고 또한 자아가 투영된 자연의 주관적 발견은 자아의 해방과 개인적 감정의 표출의 표현인 낭만주의 문학으로 이어지게 된다. 여기에 인간존재의 심층에서 울려 나오는 본능의 순수한 소리에 귀기울이며 문명에 때묻지 않은 ‘자연에의 복귀’ 를 주장한 루소 Jean-Jacques Rousseau에게서 우리는 낭만주의 문학의 선구자의 모습을 발견하게 된다. 심정과 원초적 순수에 대한 깊은 향수를 담아낸 그의 문학은, 새로운 감수성을 표현하였고 자연을 작품 속에 처음으로 진지하게 끌어들이면서, 프랑스 전기 낭만주의의 본질적인 여러 면모를 보여주며 낭만주의 문학을 꽃피우는데 가장 중요한 영향을 미쳤다.
