Fortified foods are consumed widely in modem society according to increased concern on health oriented foods. This study investigated the patterns of vitamin-and/or mineral-fortified food use among 677 teenage students(13-18 years of age) in Chungnam province and Daejeon city in Korea using questionnaire. More than 63.7% of total subjects consumed more than one package of fortified foods belonged to more than three categories of five categories including sweets/biscuits, ramyons, beverages, milk and dairy products, and breads as a frequency of more than 1-2 times/week during previous three months prior to present survey. Consumption of fortified foods was higher in middle school students than in high school students(p<0.05), and in females than in females(p<0.001). Users of fortified foods took the snacks more often(p<0.001), and they tended to believe more positively that fortification can be helpful in health maintenance than did non-users. Users preferred vitamin C and Ca(calcium) as a fortified nutrient. Major fortified nutrients in fortified foods taken by users were various; vitamin B-complex and Ca from sweets/biscuits, Ca from ramyons, vitamin C and Ca from beverages, Ca and iron from milk and dairy products and breads. These results suggest that fortified foods are used commonly and are influenced by several factors among teenagers. Types of fortified nutrient, in fortified foods taken by subjects, are various and fortification is performed unspecifically. As a consequence both nutrition education and government regulation on fortified foods should be enforced to maximize the benefits and minimize the hazard of their use.

According to the preceding research outcomes, feasibility studies on public construction projects were incorrect and subjective. To resolve the problems, Korean government initiated Preliminary Feasibility Study (PFS) system prior to undertaking the main feasibility study. The PSF can be categorized into four areas such as road, railroad, harbor, airport, and Culture & Tourism (C&T). Especially when it comes to complex due to the introduction of five-weekday working system and local $government^{\circ}{\phi}s$ self administrative system. As a result, the standardization and legislation of the PSF can not be operated effectively. Accordingly this paper seeks to 1) identify actual condition of conducted PSF in C&T; 2) set up analytical model considering cost factor of economical efficiency and seek obstacles of PSF system; 3) suggest improvement plan for construction PSF projects.

This study was carried out investigate the effect of water quality and the kind of media on the in vitro development of 1-cell and stage mouse embryos. $F_1$ hybrid mice were superovulated and timely mated. 1-cell stage and 2-cell stage mouse embryos were recruited and taken into Ham's F-10 or m-KRB media which was made of two of two kinds of water having different quality, highly purified water and tap water. 2-cell stage embryos grew up well in vitro to blastocyst or hatching blastocyst regardless of the composition of culture media, but 1-cell stage mouse embryo didn't develop well to blastocyst or hatching blastocyst in simple media like m-KRB. These results meant in vitro devleopment of 1-cell stage mouse embryo neded complex media like Ham's F-10 which contained abundant protein components. In case of quality control for water, in vitro fertilization program. observation of in vitro development of 2-cell mouse embryos up to blastocyst or hatching blastocyst media such as m-KRB would be efficatious in detecting the difference of water quality.

The purpose of this research is to revive the colors of combination dyeing and mixed dyeing with natural dyestuffs. The fabrics used were cotton and rayon. The natural dyestuffs used in this research were indigo, Phellodendron amurense, and Caesalpinia sappan. The effects of combination dyeing were as follows. First, all samples showed deeper colors. Second, according to the results of the surface K/S measurement, while the surface K/S of cotton was over 15, that of rayon was over 17. Third, the results of the light fastness measurement showed the superiority (by over grade 4) of all the samples, except in the case of rayon fiber sample no. 6 (which had been pre-dyed with indigo five times before being dyed with P. amurense once and then being dyed with C. sappan once). In the color fastness to washing measurement, all fibers showed superiority (by over grade 3~4). In addition, the color fastness to dry cleaning of all fibers was satisfactory or excellent (by over grade 3). Fourth, according to the results of the tensile strength measurement, it tended to decrease in the case of cotton and increase in the case of rayon. Fifth, the results of the density measurement showed that the density of cotton decreased by about 15~20% in the case of warp and 10% in the case of weft for all samples. The density of rayon decreased 20% in the case of warp for all samples and increased 30% in the case of weft for all samples.

The purpose of this study was to explore the experience of choosing the best days for childbirth and to understand the nature and meaning of the experience. The qualitative method of data collection was used, and in-depth face-to-face interview were conducted. Participants included four women who had given the day of birth set as the desired date. Van Manen's phenomenological method was adopted to analyze data. Four theme clusters emerged from the analysis: "The first gift to my baby"; "Collaboration with others for my baby"; "Choosing a date for childbirth such as blueprint of child"; and "Complex feelings." Our findings helped in understanding the experience of Korean women in choosing the best days for childbirth. Health care providers should offer appropriate advice and show sufficient empathy as well as emotional support by considering cultural expectations.

As the sound art field is keep growing and expanding, we shall contemplate from the sociology of the arts and cognitive science point of views to wisely accept and properly appreciate various artistic works and practices. It is because the value evaluation of new arts shall substantially involve analysis and inspections with considerations of today's complex environments, the creative productions, and the consumptions; because, such critiques are necessity for the advancement of new arts. This paper briefly introduces reasoning of including sociological analysis and criticism in evaluating sound arts beyond dichotomy of the fine arts and music fields. It also looks into changes and conditions of cultural arts grants and allowances of the interdisciplinary art genre in South Korea as it has been almost alone a playground for its domestic creative practices of the sound art. This paper is written in a hope to suggest some possible directions for future developments of these contemporary borderless and/or experimental arts.

At the multi-cultural society, research is needed to encourage a social atmosphere for enhanced understanding and respect for different cultures & countries. The purpose was to analyze the characteristics of spatial arrangement, space connection, Interior decoration and the relationship among these three features, which showed each country's unique housing form tradition. Three representative cases of historic residences from each country were selected on the basis of a recognized historic architecture directory. Total 18 residences from 6 countries - Korea, China, Japan, Rome, Egypt, and Italy - were comparatively analyzed. As results, aspects generally found in Eastern countries, were the fence as the semi-open boundary between the inside and the outside of the house, the flexibility of spatial opening and partitions between rooms, and finally simple and movable decoration features. On the other hands, aspects appeared in Western countries, were the outer wall of the building as the boundary to the outside, the closed and fixed properties of the room partitions, and finally complex and fixed decoration features. The research also showed that even within the same culture, the degree of openness varied. Each feature of space was related and could be explained within the same context. Housing, regardless of country and culture, tried to accommodate the exterior space inside the building as much as possible. The common pursuit was transformed to various visible forms and its reason might be due to different socio-cultural and environmental backgrounds that need to be continuously explored in academic area.

Since the movements of a machine are driven by a certain principle, there is a fundamental principle that governs the movement of the machine, no matter how complex and diverse it may be. Autonomous movements are a way to avoid repetition, to approach more humane and more natural factors. That's all the more so when it comes to original movements, not cloning. So now, the dynamics of the machine are more multi-sensory by human participation. It is challenging the potential to be expressed and is gradually expanding its sphere of expression in the boundaries of fact and cloning. Theo Jansen's works have changed from period to period to adapt to different circumstances, indicating that his decades-long work has continued to evolve from early to present. The evolution's focus, among other things, can be seen as having the same source of circular motion and horizontal reciprocating motion, which are repeated from the principle of organic coupling between the parts that make up the object.

The KSA caused an error in deriving the statistical measurement items due to the misconfiguration of the safety variables and sub-modules that constitute the safety statistics framework for external causes of death, and pathogenesis, without considering the academic classification system of the field and area of the disaster/accident. By naming it as a mechanism, it was analyzed that the result of poor statistical validity has arrived. Therefore, in this study, by changing the safety parameters according to the WHO safety definition and setting the sub-modules appropriately, the categories of falls, drowning accidents, and accidents exposed to inanimate mechanical forces are classified as accidents at industrial sites and work in daily life. As a result, by systematically re-establishing the complex group of statistical items of the NSO by deriving the field of disasters/accidents according to the nature of the source of external causes of death and setting the relevant domains academically, statistical validity gets better and It is anticipated to play an important role in determining the direction of safe investment.
