This study was designed to present the desirable leading line of the academic journalism, by comparing the university press with the daily newspapers. Both The Daihak Shinmun, The Korea University Press published in 1981 and The Kyungpook University Times published from 1976 to 1981 were chosen as the reference data for this research. To begin with, the writer educed the four functions of the acadmic journalism from the data, by applying the functions of daily newspapers, mass commanication to the university press. The four functions are like the following. 1. presenting and surveillancing the academic environment. 2. molding and leading the public opinion of university. 3. linking and affiliating the members of university. 4. forming a new standard of value. According to the accomplishment of these function, all the articles appeared in the university press could be sorted out into four patterns, namely, campus news, special reports, special columms, and advertisements. Depending on the examination of the data, the followings can be concluded: 1. Due to the biweekly publishing system, the function of presenting and surveillancing the academic environment can hardly be achieved. 2. Since most articles are written by students, the linking between facutly members and students each other and creating academic culture is not be carried out as required. 3. Running mainly literary works in most columns except editroial, the university press increasingly appears to take the shape of a literary megazine. 4. The commercial advertisements take up too much space and space for news reports is relatively being encroached.

저온플라즈마 처리양모의 산성염료염색에 있어서의 열역학적 고찰

이문철,홍기정 慶星大學校 1994 論文集 Vol.15 No.2

Merino wool top was treated with low temperature plasmas of oxygen(O₂) and tetrafluoromethane(CF₄) for 180 seconds, and then dyed with C. I. Acid Orange 7 in buffer solution. From the equilibrium dye adsorption at 60, 70 and 80℃ for 24∼120 hours, Adsorption isotherm and saturation dye exhaustion was observated. In addition, thermodynamic parameters such as standard affinity, heat of dyeing and entropy were obtained from the saturation values. Dye exhaustions of low-temperature plasma-treated wools increased than that of untreated at any concentration, and the saturated dye exhaustion of treated specimens for untreated increased slightly. As the dyeing temperature was heightened, it was appeared that the affinity of C.I. Acid Orange 7 for wools was higher. Especially, the difference of the dye affinity between untreated and CF₄plasma-treated wool was larger. From the decrease of heat of dyeing for the plasma-treated wools compared to untreated, it was seemed that hydrogen bond or hydrophobic bond did not contribute to dyeing of wools treated with plasmas.

Currently the evaluation of high school science and mathematics learning has been too much knowledge-centered without concerning the inquiring ability or scientific attitude. This study, therefore, was made for the purpose of establishing of evaluation model for high school science (biology and earth science) and mathematics learning and its evaluation items. In this paper, the research was done about three fields, biology, earth science and mathematics. 1. For the biology, the evaluation methods of inquiry learning were studied with the foreign references, and proper evaluation items were suggested. 2. For the earth science, after analizing 5 kinds of earth science textbook of current using in high school, essential 19 items were selected. 5 of them were tested in test group and control group, then, the results were analized. 3. For the mathematice, the teaching elements of「Set」and「Flow chart」in mathematics (Ⅰ) were selected and structured. Detailed teaching objects were established and evaluation items were introduced.

李文子,洪和子 梨花女子大學校 藥學硏究所 1964 梨花藥學硏究 Vol.- No.5

We eat vegetable more than meat as supplementary food. In such vegetable, carotene, provitamine A and other vitamines are contained. Many reports about carotene and ascorbic acid contents of vegetable are known. In this research, we pursued change by x-ray irradiation and destruction of carotene, ascorbic acid according to boiling time. We are sorry to report the result of experiment finished in a very short time.

pH 조절에 의한 쌀세척 폐수의 처리

노홍균,김지숙,이문이,조영인 대구효성가톨릭대학교 식품과학연구소 1994 식품과학지 Vol.6 No.-

여러 pH 조건 및 키토산 농도하에서 쌀세척 폐수로부터 부유성 고형물을 효과적으로 응집, 회수할 수 있는 방법을 모색하였다. 키토산 첨가에 따른 탁도감소효과는 pH가 낮아짐에 따라 작았으며 pH 6 이상에서는 키토산 농도가 증가함에 따라 현저히 컸다. 그러나, 폐수의 탁도감소는 키토산 농도와는 관계없이 pH 4일 때 가장 효과적 이었으며 pH가 증가함에 따라 저하하였다. 쌀세척 폐수내의 부유성 고형물은 폐수의 pH를 4로 조정한 후 원심분리하므로서 가장 효과적으로 침전, 회수할 수 있었다. 이 때 탁도감소는 99% 이상을 나타내었으며, 폐수내 부유물질의 농도차와 pH 조정제로 사용된 산종류는 탁도감소에 영향을 미치지 않았다. 폐수의 탁도감소 효과는 저장기간이 길어짐에 따라 저하하였다. Treatment of rice-washing wastewater was considered under various pH levels and chitosan concentrations. Compared with the control test, addition of chitosan at the various concentrations did not noticeably enhanced turbidity reduction at pH 4 and 5, but greatly enhanced at above pH 6. However, reduction of turbidity in the wastewater, irrespective of chitosan concentrations, was the greatest at pH 4 and became lower by increasing pH. Suspended solids in the wastewater were the most effectively recovered by pH adjustment of the wastewater to 4 followed by centrifugation, with over 99% reduction in turbidity. Different concentrations of suspended solids in the wastewater and various kinds of acids used for pH adjustment did not affect turbidity reduction. Increasing storage periods of the wastewater resulted in lower reductions in turbidity.

게 가공 폐기물로 부터 키틴의 분리

노홍균,이문이 대구효성가톨릭대학교 식품과학연구소 1995 식품과학지 Vol.7 No.-

게 가공 폐기물을 부가가치가 높은 키틴 자원으로 활용코자, 이들 폐기물로부터 키틴을 효율적으로 분리할 수 있는 조건을 설정하고 이로 부터 제조된 키틴의 물리화학적 성질을 조사하였다. 탈회분은 원료중량의 15배에 해당하는 1N HCl로 실온에서 30분간 교반함으로서, 탈단백질은 탈회분된 시료에 원료중량의 15배에 해당하는 5% NaOH용액으로 65℃에서 1시간 동안 교반함으로서 가장 효율적으로 이루어졌다. 탈색소는 원료중량의 10배에 해당하는 0.32% NaOCl로 3분간 처리시 가장 바람직하였다. 침지에 의한 탈회분 및 탈단백질은 교반에 비해 추출 효율성이 낮고 장시간을 요하였다. 백색의 최종 키틴제품은 질소함량이 6.45%, 회분은 0.15%이었으며, 5% lithium chloride를 함유한 N,N-dimethylacetamide용액(DMAc-5% LiCl)에서 0.1% 키틴의 점도는 12.8cP를 나타냈다. 또한 DMAc-5% LiCl에서 키틴의 용해도는 58.4%를 나타냈으며, bulk density는 입자 크기가 20~40mesh일 때 0.27g/㎖, 100mesh 이하일 때는 0.43g/㎖를 나타내었다. 입자 크기에 따른 키틴의 질소 및 회분함량에는 별차이가 없었으며, 키틴의 수율은 입자의 크기가 클수록 증가하는 경향이었다. 키틴 제조시 탈색공정은 키틴의 점도를 감소시켰으며 용해도에는 별 영향이 없었다. Procedures for isolation of chitin have been developed from crab(Chionoecetes opilio) shell waste with 26. 65% chitin on a dry basis. Optimal conditions for demineralization of crab shell were 1N HCl at ambient temperature for 30min with a solids to solvent ratio of 1: 15(w/v). Optimal deproteinization involved treatment with 5% NaOH at 65℃ for 1hr with a solids to solvent ratio of 1: 15(w/v). Effective decoloration was achieved by bleaching with 0.32% sodium hypochlorite solution for 3min with a solids to solvent ratio of 1: 10(w/v). Particular attention was given to characterization of the physicochemical properties of the crab chitin. Chitins, from four different mesh sizes of crab shell, did not show significant differences in nitrogen and ash compositions. Bleaching decreased the viscosity of chitin but did not affect its solubility.

Heterotopic ossification is frequent complication in patients with spinal cord or brain injury, although the etiology is unknown. The extensive heterotopic ossification is a cause of limitation of active or passive joint motion and ultimately bony ankylosis which interferes independency in activities of daily living and ability of maximum rehabilitation. Whereas, the articular complication of heterotopic ossification have been well documented, the vascular complication are less well known. We experienced one case with vascular compression and obstruction by heterotopic ossification in a patient with traumatic brain injury and reported the case with clinical and radiologcal and laboratoric findings.

The purpose of the present study is to examine the flow characteristics of ER fluids between 2 port and 3 port rectangular tube brass electrodes. ER fluid is made silicon oil mixed with 2-3wt% starch having hydrous particles. Flow visualization of the ER fluids were obtained by CCD camera measuring those of the clusters using an image processing technique. This research found the flow rate(Q_(L)) with 0 kV/mm, 0.5kV/mm and 1.0kV/mm for Q_(L) = 0, 0 and 5.73cm³/s. When the strength of the electric field increased, the cluster of ER fluids are clearly strong along the rectangular tube and the flow rate(Q) decreased.
