When we see the modem structure of industry, we’d like to analyse the future and the view of the Sports management with the science. The purpose of this study is that we propose materials in order to improve the quality of human’s life and the management of sports industry. 1. There are a lot of following problems in our future world; environmental pollution, the advancement of science, comparative social circumstances, the variety of value judgement. So it is necessary to study deeply about sports industry and sports management. 2. The scale of sports is so enormous that sports activity plays an important role in human’s leisure and influences on the sports industry. At the same time we have to study about sports management. 3. Sports at a lifetime that is, we must study sports which meet not only the child but also the old at the same time man or woman in the 21st century. 4. The popularization of science has raised economical level of sports in the society of sports industry. According to commercialization of sports, sports market is getting bigger.

This study aims at exploring policy directions and task on equalization of high schools in korea. In order to achieve this purpose, characteristics of secondary education in relation to life long education were reviewed. And also knowledge based society and its implications as well as status quo of selected countries were analyzed and compared. On the basis of the theoretical background, equalization policy of high school were evaluated in terms of relevancy, effectiveness, and responsiveness. Positive points of equalization policy contains normalization of middle school, expansion of educational opportunity, and education for the whole man etc. In addition to that, pursing excellency education is limited on the part of the students and parents. In the future, on the basis of the equalization principle excellency pursuing philosophy should be added.

The purpose of this study was to evaluate the nutrition status of calcium and iron in 116 elementary school students with different obesity index. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum calcium and iron levels were evaluated based on 24-recall dietary recalls, anthropometric measurements and blood analysis. The mean height, weight, obesity index and blood pressure of total subjects were 150.4 cm, 45.5 kg, 5.8% and 118.2/76.8 mmHg. The mean % of body fat, SBP and WHR were higher while LBM and TBW were lower in over weight subject than those of other group. The iron intake of overweight was lower than that of underweight and normal subjects(p<0.05) and average calcium intakes were only 50% and 60% respectively of the RDA for Korean. Serum calcium and iron levels of a three groups were within the normal range. There were no significant differences in serum calcium and iron concentrations among three groups, however those of underweight group were a slightly lower than those of other two groups. There were significantly negative correlations between iron of intake and weight, obesity index, systolic pressure and body fat percent. Systolic blood pressure was negatively correlated to the intakes of energy, carbohydrate and protein. Energy intake was also negatively correlated to serum iron. To summarize the results, calcium and iron intakes should be supplied to elementary school students, especially those who were overweight. These indicated that overweight group had improper mineral nutrition status. Therefore, nutrition education and profound studies from many different focus for overweight groups are highly required.

2-[(4-Cyanophenyl)amino]-3-chloro-1, 4-naphthalenedione (NQ-Y15) was asssayed for its genotoxic potential by using Salmonella typhimurium reversion assay and in vitro chromosome aberration test on Chinese hamster lung cells. In the Ames test, NQ-Y 15 induced his+ revertants of Salmonella typhimurium TA 98 and TA1537, reaching levels twice the negative control values. But, NQ-Y15 induced only his^(+) revertants of Salmonella typhimurium TA1537 more than twice the control values under the condition with metabolic activation system. In the cytogenetic test on chinese hamster lung cells, NQ-Y15 showed significant chromosomal aberrations, but the incidence was significantly reduced in the presence of metabolic activation.

Long term occupational exposure to solvent mixtures may cause adverse effects to the central nervous system with neurobehavioral symptoms. And some organic slovents have been suggested to cause impairment of tuberoinfundibular dopaminergic activity and neurochemical mechanisms controlling pituitary secretion. For the purpose of assessing neuroendocrine effects in occupational solvents exposure, hormonal study settings (shoes-manufacturing industry & fishing products industry) and compared with nonexposed controls(33 men, 85 women). Male workers exposed to solvent mixtures had significantly lower plasma level of follicle-stimulating hormone(FSH) than nonexposed male controls. While female workers exposed to solvent mixtures had significantly lower plasma levels of growth hormone(GH), and thyroid-stimulating hormone(TSH) than nonexposed female controls. The results of significant decrease in plasma concentrations of pituitary hormones(FSH, GH, and TSH) in workers exposed solvent mixtures indicate that occupational exposure to solvent mixtures may induce neuroendocrine effects through an effect on hypothalamic pituitary axis.

Gastrointestinal stromal tumors (GISTs) are common mesenchymal tumors that arise in the wall of the gastrointestinal tract. We report a case of obscure gastrointestinal bleeding due to a GIST of the jejunum successfully documented by videocapsule endoscopy (VCE) and single-balloon enteroscopy (SBE). A 36-year-old man with hematochezia was referred for further evaluation of no evidence of bleeding focus on esophagogastroduodenoscopy and colonoscopy. A VCE showed a suspicious ulcerative hyperemic mass that located in about 1 hour apart from duodenal second portion. SBE revealed a nonbleeding 4×2 cm mass with an ulcer at the proximal jejunum. The patient underwent laparoscopic resection without complication. Histological examination revealed a well circumscribed, dumbbell-shaped firm mass comprised of spindle cells. Immunohistochemical staining for CD 117 was diffusely positive, whereas staining for S-100, CD 34 and MIB-1 was all negative. It was confirmed to be a low-grade GIST at the proximal jejunum.

Double primary cancers are two independently developed cancers in an individual. There have been some reports on double primary cancer since Billroth reported it for the first time in 1879. Double primary cancer of the stomach and esophagus has been revealed a very low incidence worldwide. The incidence of an esophageal cancer with another primary cancer is reported to be 9.5∼27%, but double primary cancers in the esophagus and stomach have been rarely reported to our knowledge. In this study, we present here a case of double primary esophageal and stomach cancer in a 66-year-old man because of progressive dysphagia.
