Fungal strains producing extraordinary high amounts of arachidonic acid(ARA) and eicosapentaenoic acid(EPA) were isolated from soil samples and the effects of various culture condition on the production of ARA and EPA were investigated. Three strains of fungi with the high acids yields were identified as Mortierella alpina 49, M. parvispora 58 and M. horticola 73. Highest amounts of EPA and ARA were produced when three strains were cultivated at 18℃ for 4 and 6 days, respectively. When the three strains of fungi were grown in a medium with increase of 5% glucose, EPA production was decreased in every case, whereas ARA production not decreased in every case. There was no significant effect of oxygen on the fungi growth. But the production of EPA and ARA as well as the total fatty acids decreased when cultivated in 200 ml of culture volume in 500 ml flask. When the fungi cultivated for 6 days at 18℃ and stand for 6 days at room temperature, there was no difference in growth amount, while there was increase in the total fatty acid production, i.e., 36% increase as for M. parvispora 58 and 10∼20% as for the other two fungi. Aging didn't influence the EPA production much. the amount of the fungi growth and the total fatty acid production increased with more soybean oil addition as a nutrient of culture medium.

The browning color development during drying of sliced garlic flakes was greatly dependent on drying temperature and moisture content, and the reciprocal proportion between the formation rate of browning color and the reduction rate of reducing sugar was found. The browning color development during drying of the flakes was effectively impeded with sulfiting concentration of 0.1%, 0.5%, and 1.0% at drying temperature of 65℃, 75℃ and 85℃, respectively. The reduction of pyruvate during drying of the flakes was greatly influenced by drying temperature and sulfiting concentration, and the remarkable reduction of it has been analyzed when above 85℃ of drying temperature and above 1.0% of sulfiting concentration. Sulfiting treatment showed antimicrobial activity which diminished bacterial flora from 5.7×10^5 for control to 9.9×10^4 after treatment of 1.0% sulfiting solution in dehydrated products of sliced garlic flakes.

This study is designed to make an analysis of the differences of excellent female and male athletes and non-excellent female and male university Judo athletes per weight. The researcher identified the valid scoring skills of each athlete on the basis of the event record papers of 2003 Spring and Fall University Judo Federation Match in Korea and 2004 Spring University Juder Federation Match in Korea, dividing the atheltes into two groups: one is composed of the excellent athletes who won the first, second and third prizes; and the other is made up of the non-excellent athletes who didn't. Based on the records, the researcher used SPSS PC+Ver 10.0, depending on x² test and frequency analysis(%) so as to analyze the frequency of using skills in case of male and female athletes and the skills used per weight and sex and the skills per match in case of the athletes as a whole. This study is mainly designed to make an analysis of the skills used by the excellent and non-excellent athletes and the differences of their skills per weight. The following are the results. First, the survey on valid scoring skills per weight indicates that 30.7 percent of the male subjects made use of hand skills and that 25.2 percent of them made the most frequent use of foot skills. Second, the survey on the scoring skills per contest shows that the male subjects used hand skills frequently in case of the first, second, third, fourth and fifth contest and that the female subjects made the most frequent use of foot skills in case of the first, second, third and fourth contest. Third, the subjects weighing -60, -66, -90, and -100kg made the most use of hand skills, and the subjects with -73kg turned out to made the most frequent use of foot skills. The female subjects weighing -48, -52, -70, -78, and +78kg made the most use of foot skills and the subjects weighting -57 and -63kg turned out to win due to their opponents' withdrawal. Fourth, the excellent male subjects made the most frequent use of hand skills (34.3%) and the non-excellent male subjects made high use of hand skills(29.3%). The female excellent athletes turned out to make high use of the pressing skill(27.3%) and the non-excellent athletes used hand skills(30%). Fifth, in terms of the excellent athletes scoring skills per weight, the male subjects used hand skills most frequently in case of their weighing -60, -81 -90, and -100kg and those who weigh 66, and -73kg made frequent use of foot skills. The non-excellent male subject used frequent use of hand skills in case of their weighing -60, -66, -73, -81, and -100kg and the female subjects made the most use of foot skills in case of -48, -52 -57, -70 and +78kg, and hand skills in case of those with -63kg, and subjects with -78kg used waist skills. The nonexcellent subjects used foot skills in case of their weighing -48, -52, -57, and +78kg and hand skills in case of -63, and -70kg, and wining the matches from the opponents' withdrawal. On the basis of the data above, the research would like to suggest that the following things should be further investigated. First, the research has it that male subjects made the most use of hand skills but that female subjects used foot skills more frequently. Coaches should keep this in mind and look for measures. It is also necessary to make a more specific analysis of ramified skills per skill. Second, this study is limited by the number of the subjects and future studies should deal with more subjects and coaches should work on skill training methods. Third, future studies should focus on the variables of time, or the winning points of valid scoring points and all the subjects in terns of the use of skills.

This study was conducted to obtain basic information about seasonal changes of fatty acid compositions and physicochemical characteristics in bakery margarines manufactured in spring, summer, fall, and winter for quality improvement of domestic bakery margarines. Correlations among the physicochemical parameters was also investigated. The results showed that melting point(MP) and iodine value(IV) significantly changed according to seasonal changes. However, there was hardly any difference in water and salt contents and saponification values(SV) in same brand by seasonal changes. The major fatty acids were palmitic, stearic, oleic and linoleic acids, and lauric acid contents were high for some samples. For most of samples, solid fat content(SFC) at 33.3℃ was more than 3.5%, and average SFC and consistency for products manufactured in summer were higher than those in winter. There were no significant seasonal changes in whipping value. The temperature showing the most desirable hardness was about 24.5℃, 30.6℃, 26.5℃, and 23℃ for spring, summer, fall and winter, respectively. The MP and the SFC at 21.1℃ were significantly decreased with increasing the content of polyunsaturated fatty acid, and the MP decreased with increasing the IV. These tendencies are more apparent for products with the SV below 200. However, the oil off value was significantly increased with increasing the consistency irrespectively of the SV.

This study was designed to investigate the change of chemical composition of the serum and urine in humans after the MSG administration. Healthy Korean adult men were used for experimental objects. The experimental groups were divided into three groups receiving, one, three and five gram dosages, respectively. These groups were investigated as to the change of chemical composition in the serum and urine 2 and 24 hours after the administration. These findings were compared with the pre-administration condition. The results obtained are summarized as follows: 1) Among all experimental groups, the pH value, the non-protein nitrogen and the protein nitrogen content in the serum showed no marked changes after the administration, as compared to before the administration. 2) Among all experimental groups, the ammonia-nitrogen content in the serum, as compared to before the administration, decreased 2 hours after the administration but the urea-nitrogen content increased. 3) among all experimental groups, the blood sugar content in the serum increased slightly 2 hours after the administration, but the cotnent returned to the same level as before the administration. 4) Among all experimental groups, the albumin, α_1-, α_2- and γ-globulin content in the serum protein after the administration, as compared to before the administration, showed no market changes each time but the β-globulin content increased slightly after the administration. 5) Among all experimental groups, the urea-nitrogen and ammonia-nitrogen content in the urine after the administration, as compared to before the administration, increased slightly but the creatine and creatinine content showed no marked changes each time.

"Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.
