The development of the growth theory narks a turning poiot in the history of education theory in this country, Progrssive Education is the application of Dewey's philosophy of education. Education for growth, a statement of educational purpose most generally consistent with pragmatism, had its most explicit formulation in the philosophical work of Dewey Expositors of education for growth begin with two assumptions ; First, children are immature and, because of theis native ability to learn, are traveling down the road to maturity. Second, as they travel this long road, one frequently filled with all kinds of obstacles, They have the right to espect from the schools a course of enstruction providing them with habits for meeting and mastering existing conditions and, moreover, for adjusting thein skills and their behavior to novel conditions. Children in educational circum tances of any kind, have a capacity for growth, and this growth is best when it enables children to use their capocity in connection with new aims. Growth is a natural characteristic of life, It has no end beyond itself. The point is that education. When educational purpose is defined as growth, it means that schools must kindle in students a desire for growth, and this kindling involves opplying the artistry of teaching without at the sams time descending into any kind of compulsion or routine traing, the necessary and appropriate means to ensure personal growth must form the seed and the motive force for decent educational accomplishment.

Adsorption characteristics of toluene vapor, which is one of important source of volatile organic compounds (VOCs), by activated carbon were investigated using a fixed bed adsorption column. The operating parameters such as breakthrough curve, adsorption capacity. mass transfer zone (MTZ), and length of unused bed (LUB) were studied. The experimental results showed that the breakthrough time decreased with increasing inlet toluene concentration and gas flow rate. MTZ and LUB increased with the increase of inlet concentration, gas flow rate, and particle size of activated carbon. The adsorption capacity increased with the increase of inlet toluene concentration, while it decreased with increasing particle size. However, it was kept at constant value regardless of the increase of gas flow rate. Adsorption isotherm of toluene vapor could be represented by the Freundlich adsorption equation fairly well. From the adsorption experiments using some VOC gases such as toluene, xylene, butyl acetate. butanol and acetone, it was also found that the adsorption capacity was higher in the case of gas with higher boiling point and lower vapor pressure.

林鍾弼,卜鎭尤 又石大學校 1988 論文集 Vol.10 No.-

Banhasasim-tang, chinese medicine, has been used for the treatment of the gastric ulcer and cimetidine, H_2-receptor blocker, has been also used as the gastric ulcer remedy. Therefore the concurrent administration of these two drugs may increase antiulcer activities more than administrating one by one. In order to investigate antiulcer activities, some experiments were conducted. The results obtained were as follows; 1.The concurrent administration of Banhasasim-tang and cimetidine given intraperitoneally (cimetidine 50㎎/㎏+extract 300㎎/㎏ and 50㎎/㎏+500㎎/㎏), significantly inhibited Shay ulceration in rats (12 hr ligation). 2.Aspirin ulcers induced by the administration of aspirin 200㎎/㎏(p.o) to pylorus-ligated rats were inhibited by the concurrent administration of Banhassasim-tang and cimetidine. The combination of these two drugs (cimetidine 50㎎/㎏+extract 100㎎/㎏, 50㎎/㎏+300㎎/㎏ and 50㎎/㎏+500㎎/㎏) resulted in a potentiated effect on the inhibition of the ulceration. 3.Indomethacin ulcers induced by intraperitoneal injection of indomethacin 20㎎/㎏ were inhibited by the concurrent administration of Banhasasim-tang and cimetidine. The combination of these two drugs (cimetidine 50㎎/㎏+extract 100㎎/㎏. 50㎎/㎏+300㎎/㎏ and 50㎎/㎏) resulted in a potentiated effect on the inhibition of the ulceration. 4.The antiulcer actions by the concurrent administration of Banhansasim-tang and cimetidine against Indomethacin ulcers were more effective than those against Aspirin ulcers or shay ulcers.

The purpose of this study is to investigate the interrelationships on integrated science process skills and Piagetian cognitive modes for high school students according to the different cognitive reasoning levels. About 509 high school students were randomly selected for the samples of this study. They were identified as concrete, transitional and formal operational stage with the scores of GALT(Group Assessment of Logical Thinking) developed by Roadrangka, Yeaney and Padilla(1982), and TIPS Ⅱ(Test of Integrated Process Skills) developed by Burns, Wise and Okey(1983). The result of this study were showed that about 11.8% of the samples were in the concrete operational stage and about 24.4% of the samples were in the transitional stage, while about 63.8% of them were in the formal operational stage. It was also found that the achivement scores of the science process skills increase in accordance with the cognitive reasoning levels. The value of the correlation coefficient between science process skills and cognitive reasoning abilities was 0.49, which was significant at the 0.05 level. This finding seems to support previous research that the student's cognitive resoning abilities appeared to have influenced student's scores of the science process skills No differences to the logical reasoning ability between male and female students according to each cognitive level were found except formal operational stage.

Background: Licorice has been widely used for its anti-inflammatory action. Recently many studies have revealed that licorice has an inhibitory effect on melanin formation by inhibiting tyrosinase, TRP-1(Tyrosinase-related protein 1) and TRP-2(Dopachrome tautomerase) activity. Most studies have reported that licorice extract inhibits melanogenesis in malignant melanoma cell but there are few reports of the effect of licorice on proliferation and melanization in normal human melanocytes. Furthermore, anti-melanogenetic effect of licorice is different according to the cultivated places. Objective: This study was done to investigate the effects of crude extract(CLE) and oil-soluble extract(OLE) of licorice which is cultivated in China and circulates in Korea on the proliferation and melanization of normal cultured human melanocytes. Methods: CLE(100, 500, 1000㎍/mL) and OLE(1, 10, 100㎍/mL) were added into culture medium respectively. Three days after adding CLE, melanocytes were counted by using hemocytometer, and melanocyte proliferation was measured by MTT and SRB assay. And melanin contents were examined by using spectrophotometer. Melanocytes were counted and melanin contents were measured 2 days and 7 days after adding OLE. Results: In CLE-added groups, the number of melanocytes was significantly lower in experimental groups (500㎍/mL and 1000 ㎍/mL) than in control group(p<0.05). On MTT assay, the proliferation of melanocytes was inhibited significantly in experimental groups(500㎍/mL and 1000㎍/mL) (p<0.05). On SRB assay, the proliferation of melanocytes was inhibited significantly in all experimental groups(p<0.05). This anti-proliferative effect was supposed to be related with the cytotoxic effect of CLE. Melanin contents increased significantly in CLE-added experimental group(500㎍/mL and 1000㎍/mL) than control group(p<0.05). It is considered that the increased melanin contents were caused by strong anti-proliferative effect. Two days after adding OLE, the number of melanocytes had no change in 1㎍/mL-added group, which decreased significantly in 10㎍/mL-added group, All cells were detached from the bottom of culture plate in 100 ㎍/ml-added group. The number had no change in 1㎍/mL-added group, while all cells were detached in 10㎍/mL and 100㎍/mL-added groups 7 days after adding OLE. This means that the concentrations of 10㎍/mL and 100㎍/mL of OLE have cytotoxic effect on melanocyte. Melanin contents decreased significantly on the 2nd day(p<0.05), and decreased slightly on the 7th day in 1㎍/mL OLE-added group. Conclusion: Oil-soluble extract of licorice which is cultivated in China and circulates in Korea has anti-melanogenic effect. Therefore, this material can be used to treat hyperpigmented disorders including melasma.

The tree observation tehnique is being highlighted as a reasearch area for deterioration of insulation because of high-voltage power system. Many reseachers make efforts to develop not only diagnosis of aging state but also detection of defects in the initial stage from preventive diagnosis system. For the measurement of tree, image processing is actively studied as a experimental technique of electrical tree, because the conventional directed visual impossible to analyze on the tree degradation area, progressed direction, and tree pattern etc. In this paper, we have developed the tree measuring system using image processing. By using an image processing technique, the tree features which appear immediately after the tree initiation as well as changes in the configuration of the tree can be easily measured and observed than the conventional visual methods.

This study examined, as the one way of using zeolite, the about the removal of ammonia nitrogen and phosphorus that cause the eutrophication occurred the adjoining seas.4A type zeolite was used as an adsorbent to remve NH_4-N, PO_4^3-P ion in the artificial seawater. Zeolite is more required than in the fiesh water, under the same conditions, in order to remove NH_4-N in the sea water. The lower the thickness of NH_4-N is in the early stage, the more Freundlich type equation the value of 1./n increases. In case of PO_4^3-P indicated that the removal efficiency was relatively independent of PO_4^3-P concentration. Freundlich parameter 1/n has the value nuder 2. So it shows that absorption is made with relatively ease.
