산업적으로 경쟁력이 있는 젓갈을 제조하기 위한 목적으로 본 연구는 현재까지 연구된 저식염 젓갈에 Koji를 첨가하여 젓갈의 속성제조 및 풍미성분의 개량을 시도하여 보았다. Koji를 첨가한 저식염 멸치젓은 숙성 30일경에 완전히 숙성되었으며 이때 아미노질소 함량도 가장 높았다. 지방 및 단백질 분해효소의 활성은 대조구 및 Koji첨가 시료 모두 숙성 20일 및 30일경에 가장 높았고 그 후로 감소하였다. 단백질 분해균은 Koji의 경우 숙성 20일경에, 대조구는 숙성 30일경에 가장 많았으며 그 후로 감소하였다. Koji를 첨가한 저식염 멸치젓은 재래식 기존 젓갈에 비해 단기간에 숙성시킬 수 있었다. The adding effect of Koji, made by Aspergillus oryzae, in low salt-fermented anchovy paste was studied to reduce fermentation time and to enhance flavor quality as a commercial feasibilty in seafood industry. The content of volatile basic nitrogen increased slowly during fermentation, whereas that of amino nitrogen was the highest in 30days of low salt-fermented anchovy made with Koji. Protease and lipase activity in anchovy paste, which made with or without Koji, were high amount in 30 and 20 days of fermentation, respectively. A number of proteolytic bacteria was high level in 13 days and then slowly decreased afterward.

The present study undertaken to investigate the interrelationship among their regular dietary fatty acid intake, body fat content(BFC), and plasma lipid fractions(PLF) of middle-aged Korean women. Forty-nine women(age 30 to 49) participated in this study in which the aim was to determine their total nutrient intake per day, BFC and PLF, and to analyse the intercorrelations of these. Strong correlation was seen among their body mass index, mid-upper-arm-circumference, and BFC which were positively correlated with plasma total lipids(TL) and triglycerides(TG). Dietary myristic acid and lauric acid were positively correlated with both total cholesterol(TC) and LDL-cholesterol(LDL-C) in plasma. Palmitic acid, stearic acid, oleic acid, and total monounsaturated fatty acid(MUFA) were negatively correlated with HDL-cholesterol(HDL-C). Although dietary total saturated fatty acid(SFA) was not correlated with TC and LDL-C, it was positively correlated with TL and TG in plasma. However, dieary n-3 polyunsaturated fatty acid(PUFA) in regular Korean diet was not correlated with any of lipid fractions in plasma which might he due to the high ratio of n-6/n-3 in their diet. From the above results, it was concluded that plasma lipid fractions were modulated by their dietary nutrients, especially the types of the fatty acids. Dietary SFA and MUFA intake not PUFA are strongly correlated with LDL-C and HDL-C in the Korean diet. This may relate to the frequency of coronary heart disease in the age group.

주은희,손명수,차천수,황인성,김성수,한천구 대한건축학회 2004 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.24 No.1(구조계)

In this paper, setting and strength development of cement mortar are discussed under various mineral admixture content and curing temperature. Setting time exhibited an increasing tendency with an increase in curing temperature. Under low curing temperature, use of CKD resulted in a reduction in setting retarding, whereas FA and BS retarded the setting time of cement mortar. For compressive strength, high curing temperature and age leaded to an increase in compressive strength of concrete. Under low curing temperature, the use of CKD resulted in an enhancement of compressive strength at early stage, and exhibited a similar level of compressive strength with plain concrete. For this reason, use of CKD in cold weather concreting has positive effect on strength development at low curing temperature under early age.

The objective the paper is to investigate the physical and mechanical properties of concrete incorporating mineral admixtures. For setting properties, at low curing temperature, setting time of concrete with mineral admixture is delayed compared with that of plain concrete. But, use of cement kiln dust(CKD) has a desirable effect on reducing setting retard under low curing temperature. For compressive strength, concrete with FA and BS have low strength at early stage compared with that of plain concrete under low curing temperature. However, the use of CKD resulted in an enhancement of compressive strength at early stage under low curing temperature, and exhibited a similar level of compressive strength with plain concrete. For this reason, use of CKD in cold weather concreting has positive effect on strength development at low curing temperature under early age.

In order to develop an appropriate health care service program for a population. it is of utmost importance that the particular population's demograhic and socio-economic characteristics are taken into consideration. The purpose of this research was to determine which of the demographic and socio-economic factors gathered from basic family health records contribute to the decision by people to use either the hospitals and clinics. or health centers for their children's health care. The target area of this study was Guro 6 dong. Guro-Ku, Seoul. A sampling method of choosing families whose children(1-3 years old) had already received their third DPT vaccination resulted in 405 subject familes out of 3904 family health records which were on file at the Guro 6 dong health subcenter A general survey of the households under study revealed that 61.9% of the children received the vaccinations at a health center. and 38.1%. at a clinic or a hospital. The demographic. socio-economic. and maternal health behaviour characteristics were all analyzed for each of the 405 families. In addition. the likelihood of each family to use either the clinic and hospital or the health center was analyzed. Significant differences in the data were determined by the Chi-squared methcd. The factors affecting the utilization of medical facilities ware examined through a stepwise discriminant analysis. using the type of medical facility utilized as group variable, and the demographic characterlistics socio-economic characteristics. or maternal health behaviour as discriminant variable. 1. Of the demographic characteristics. father's education. the mother's age. mothor'education. and the mother's occupation had a hit ratio of 58.0% 2. Upon the analysis of socio-economic characteristics, type of housing, status of ownership of the house, household income, and whether the family had a telephone had a hit ratio of 69.9%. 3. Using maternal health behaviour. as the discriminating variable, and prenatal care, postpartum care had a hit ratio of 70.9%. 4. The stepwise discriminant analysis resulted in postpartum care, type of housing, ownership status of the house, mother's occupation, monthly income, and ownership of telephone having a hit ratio of 73.4%. The collection of basic health information of a population is essential for planning an appropriate health care service program. This research has shown that, as part of the basic information, demographic, and scoio-economic, as well as maternal health behavior characterisics are very important in determinizing an individual's preference for a particular type of medical facility from the available ones. Furthermore, these specific characteristics of a population may be used in planning a comprehensive health care service program to make certain appropriate facilities and programs are available. More need to be done in the future to discover the factors which influence the effective utilization of health service programs available to the population.
