The status of facilities, management of the experiment, practices, and Science education teaching method in middle school have been investigated. The present status and reasonable management of middle school science education have been grasped from the questionaires. The results are as follows : The reasonable management for expeiments and practices of science education were scanty in the middle school around the urban and rural schools owing to the shortage of facilities and equipments, crowded class, excessive classes, work for teachers, excessive contents of present textbook and insufficience of administrative support etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper.

Chung, Ill-Min,Lim, Ju-Jin,Ahn, Mun-Seob,Jeong, Haet-Nim,An, Tae-Jin,Kim, Seung-Hyun The Korean Society of Ginseng 2016 Journal of Ginseng Research Vol.40 No.1

Background: The study of phenolic compounds profiles and antioxidative activity in ginseng fruit, leaves, and roots with respect to cultivation years, and has been little reported to date. Hence, this study examined the phenolic compounds profiles and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free-radical-scavenging activities in the fruit, leaves, and roots of Korean ginseng (Panax ginseng Meyer) as a function of cultivation year. Methods: Profiling of 23 phenolic compounds in ginseng fruit, leaves, and roots was investigated using ultra-high performance liquid chromatography with the external calibration method. Antioxidative activity of ginseng fruit, leaves, and roots were evaluated using the method of DPPH free-radical-scavenging activity. Results: The total phenol content in ginseng fruit and leaves was higher than in ginseng roots (p < 0.05), and the phenol content in the ginseng samples was significantly correlated to the DPPH free-radical-scavenging activity ($r=0.928^{****}$). In particular, p-coumaric acid ($r=0.847^{****}$) and ferulic acid ($r=0.742^{****}$) greatly affected the DPPH activity. Among the 23 phenolic compounds studied, phenolic acids were more abundant in ginseng fruit, leaves, and roots than the flavonoids and other compounds (p < 0.05). In particular, chlorogenic acid, gentisic acid, p- and m-coumaric acid, and rutin were the major phenolic compounds in 3e6-yr-old ginseng fruit, leaves, and roots. Conclusion: This study provides basic information about the antioxidative activity and phenolic compounds profiles in fruit, leaves, and roots of Korean ginseng with cultivation years. This information is potentially useful to ginseng growers and industries involved in the production of high-quality and nutritional ginseng products.

Effects of Taeyeumjoweetang and exercise administration on enzymes and fat accumulation of the liver tissue in rats. Exercise Science, 11(2): 345-358, 2002. Taeyeumjoweetang is associated with improving liver function as wall as improving lipid profile. These factors are known to reduce body fat mass in re Taeyeum person'. Exercise also can improve liver function in patients with fatty liver. The purpose of this study was to investigate the effects of both Taeyeumjoweetang and exercise on enzymes and fat accumulation in rat's liver cells. 40 Sprague-Dawley rats(14weeks old)were randomly assigned into four group; the control group(n=10), the herb tea group(n=10), the exercise group(n=10) and the herb+exercise group(10). The herb tea group were given the consumption of 50㎖ of the herb tea a day for 8weeks. The exercise protocol consisted of treadmill running for 8 weeks. The data fof TC, LDL, HDL and Al were measured in plasma Wood, and GOT and GPT were measured in liver tissue. An alpha level of .05 was used as the criteria for significance. The Obtained results are as follows: 1. There were significant differences in body weight among three groups. The herb+exercise group was lower significantly than other group. 2. There were significant differences in liver weight among three groups. The herb+exercise group was lower significantly than other group. 3. There were significant differences in TC, LDL and Al among three groups. The herb+exercise group was lower significantly than other group. But HDL levels in the herb+exercise group was highly significantly than other group. 4. There were significant differences in GOT, GPT among three groups. The herb+exercise group was lower significantly than other group, showing lowest liver cell damage. 5. In composition material quantity of liver' cell cytosol shown by Hematoxylin-eosin stain, The herb+exercise group was lower significantly than other group. 6. As results of lipid and glucose stain, The herb+exercise group was lower significantly than other group in fat accumulation and glucose levels. These findings demonstrate that both the herb tea and exercise have an effect to reduce fat and glucose accumulation but exercise effects is higher than these of the herb tea. Also these effects is highest brought about by the herb+exercise.
