Rapeseed(Brassica napus L.) is an important oil crop as a vegetable oil, concentrated feed and industrial materials. The name "canola" was registered in 1979 by the Western Canadian Oilseed Crushers Association to describe "double-low" varieties. Double low indicates that the processed oil contains less than 2% erucic-acid and the meal less than 3mg/g of glucosinolates. Today annual worldwide production of rapeseed is approximately 35 million tons on 24 million hectares. China accounts for 33% of the world production and the European Economic Community for nearly 32%. Canola ranks 3rd in production among the world's oilseed crops following soybeans, sunflowers, peanuts and cottonseed. The recent advances in genomics and in gene function studies has allowed us to understand the detailed genetic basis of many complex traits, such as flowering time, height, and disease resistance. The manipulation of seed oil content via transgene insertion has been one of the earliest successful applications of modern biotechnology in agriculture. For example, the first transgenic crop with a modified seed composition to be approved for unrestricted commercial cultivation in the US was a lauric oil, rape-seed, grown in 1995. There were also some significant early successes, mostly notably the achievement of 40% to 60% lauric acid content in rapeseed oil, which normally accumulates little or no lauric acid. The name "$\textrm{Laurical}^{TM}$" was registered in 1995 by Calgene Inc. Nevertheless, attempts to achieve high levels of other novel fatty acids in seed oils have met with much less success and there have been several reports that the presence of novel fatty acids in transgenic plants can sometimes lead to the induction of catabolic pathways which break down the novel fatty acid, i.e. the plant recognizes the "strange" fatty acid and, far from tolerating it, may even actively eliminate it from the seed oil. It is likely that, in the future, transgenic oil crops and newly domesticated oil crops will both be developed in order to provide the increased amount and diversity of oils which will be required for both edible and industrial use. It is important that we recognize that both approaches have both positive and negative points. It will be a combination of these two strategies that is most likely to supply the increasing demands for plant oils in the 21st century and beyond.ant oils in the 21st century and beyond.

Purpose - The purpose of this study was to develop a motivation scale for participation sport tourism and to produce implications of potential use of MSPST for sport tourism distribution emphasizing the needs of sport tourists and the functions required to satisfy those needs. Research design, data, and methodology - The Motivation Scale for Participation Sport Tourism (MSPST) was developed in three stages. A literature review generated 8 dimensions with 42-items in the first stage. Second, an expert review phase refined the initial item pool, which resulted in 35 items. Result - Exploratory factor analysis was employed to produce an 8-factor, 28 item pool. The reduced version was confirmed via structural equation modeling, indicating an acceptable model of fit. The final MSPST consisted of 8 dimensions of motivation, including friendship, family, solitude, challenges, intrinsic, achievement, nature, and competition. Conclusions - The MSPST is a valid and reliable scale of tourists' motives for participating in sports. The results supported the suggested measures of motives associated with participation sport tourism regarding construct, convergent and discriminant validity. A body of knowledge about motives provides insights for policy-makers seeking to support distributional industries for sport tourism and finally to promote economy on both regional and national levels.

Purpose: This study aimed to determine dental technicians' job satisfaction levels and to assess its influence on turnover intention. Methods: We included 230 dental technicians who work within Seoul, Incheon, Daejeon, the Gyeonggi Province, and the Chungcheongnam-do Province. We carried out a self-reported survey using a structured questionnaire. Results: As a result of assessing the research subjects' job satisfaction level, we found that there was a significant difference in working hours and a dental-work continuing plan sphere (p<0.05). Achievement & self-realization factors, the human relation factor, and growth & development factors were reported to be major job satisfaction indices. The whole average of the job satisfaction level came to 3.11, thereby appearing to be relatively high. In analyzing the research subjects' turnover intention, there was a significant difference in age, task field, dental-work career, working hours, incumbency, and dental-work continuing plan sphere (p<0.05). The question average for turnover intention was 2.88. As a result of assessing a correlation between job satisfaction and turnover intention, a significant negative (-) correlation was found between job satisfaction and turnover intention. Thus, a higher job satisfaction level was observed to lead to a lower turnover intention. Conclusion: As a result of conducting a regression analysis in order to assess the influence of job satisfaction on a turnover intention, a working condition factor, a human relation factor, and a recognition factor each appeared to have a high impact.

There seems to be a public consensus that the content of Korean mathematics textbooks is extensive and of a high level of difficulty. However, such judgment is the result of a generalization based on individual experience or on the results from comparisons of the international levels of achievement. Therefore, a more objective and stricter approach to the determination of the quantity and level of difficulty of mathematics content is necessary. For this purpose, this study has compared the content of Koreas 6th and 7th junior high school curriculums, and the Korean mathematics curriculum to textbooks of the United States, which has a considerable influence on the making of Korean mathematics textbooks. First of all, a comparison of Koreas 6th and 7th junior high school mathematics curriculums showed a slight reduction in the total quantity of content, as more content was deleted than was added in the 7th curriculum. However, given the fact that the number of hours of mathematics classes has been reduced, the reduction in content cannot be regarded as anything more than a simple reflection of the reduction in hours, proving that the 7th curriculum has not met its revision objective of reducing the content by 30%. Meanwhile, the comparison of the United States junior high school mathematics textbooks to Korea's 7th curriculum showed that the 7th grade content in the United States was much broader, encompassing content which in Korea ranged from the 2nd grade of elementary school to the 2nd year of junior high school. Therefore, on the surface, it may appear that the overall level of content in the American mathematics textbook is lower than that of the Korean. However, there are several cafes, such as statistics and probability, where certain content was more difficult and introduced at an earlier grade in the United States than in Korea. In fact, it can be said that Korea students tend to find content of the mathematics textbooks to be harder than they actually are because they are delivered as a mere aggregate of algorithms, with little consideration to its application in their everyday lives. In this respect, there is much room for improvement on the mathematics textbooks of Korea.

In 1967, the problem of occupational lead exposure came to public attention in Korea. Since then, regular progress has been made in lowering workplace lead exposures, instituting new workplace controls, and implementing health examinations of exposed workers. Past serious lead poisoning episodes made it possible to introduce biological monitoring programs on a voluntary basis in high-lead-exposure facilities in Korea. Industry-specific occupational health services for lead workers in Korea during the last 22 years can be categorized into three phases. During the first phase (1988-1993), efforts were directed at increasing awareness among workers about the hazards of lead exposure, biological monitoring of blood zinc protoporphyrin began, and a respiratory protection program was introduced. During the second phase (1994-1997), a computerized health management system for lead workers was developed, blood-lead measurement was added to biologic monitoring, and engineering controls were introduced in the workplace to lower air-lead levels to comply with air-lead regulations. Finally, during the third phase (1998-present), a new biomarker, bone-lead measurement by X-ray fluorescence, was introduced. Bone-lead measurement proved to be useful for assessing body burden and to demonstrate past lead exposure in retired workers. Occupational health service practice for lead workers, including the industry-specific group occupational health system, has brought considerable success in the prevention of lead poisoning and in reducing the lead burden in Korean lead workers during the last several decades. The successful achievement of prevention of lead poisoning in Korea was a result of the combined efforts of lead workers, employers, relevant government agencies, and academic institutes.
