The objectives of this study were to assess food intake frequency and food behavior of infants and toddlers by using the Nutrition Quotient (NQ). A total of 368 subjects (infants 111, toddlers 257) in Ganghwa county were analyzed in this study. The NQ was examined using an NQ questionnaire, which consisted of 19 food behavior checklist items. The items were grouped into five categories: balance, diversity, moderation, regularity, and practice. All data were statistically analyzed by SPSS 20, and significant difference was evaluated by Student's t-test and $x^2-test$. The BMIs of infants and toddlers were $16.54kg/m^2$ and $16.01kg/m^2$, respectively. The frequencies of consumption of vegetables and fruits were higher (p<0.001) in girls and toddlers compared to boys and infants, respectively. Food behavior of meal regularity (p<0.001), breakfast eating (p<0.001), and chewing well (p<0.001) were also higher in toddlers compared to infants. Total NQ score of infants and toddlers were 62.05 and 64.91, respectively, which were within medium grade. The NQ score of toddlers was higher than that of infants (p<0.0.5). NQ score was positively correlated with parent's education, monthly income, age, and exercise. Therefore, children and their parents need proper nutrition education and counseling to correct their eating habits and improve their nutritional status.

Relationships between immigrant mothers' Korean language ability and preschoolers' language development in multi-cultural families were studied with 91 mothers and their children. Language capacity of mothers and children was measured by receptive and expressive vocabulary test, sentence comprehension test and two kinds of reading tests. Results showed that mothers' level of comprehension was relatively low but their reading ability was higher than that of elementary school first-grade Korean students. Comprehension of children in multi-cultural families with non-immigrant counterparts showed a lower level of language ability. Mother's level of expressive vocabulary, receptive vocabulary and reading ability correlated with children's language development. These results indicate a relationship between children's delayed language development in multi-cultural families and mother's low proficiency in Korean language.

This study was conducted to detect the correlations and the main factors influencing self-directedness in learning of nursing students. Method: The samples were composed of 224 nurse students who were from three nursing department in Seoul, Chungnam & Kyunbook. The reliability of 4 instruments was tested with Cronbach's $\alpha$ from .63 to .86. The data was analyzed using a SAS program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Result: The results were as follows: 1. The mean self-directedness score was 91.23 which was slightly high. The self-directedness in learning was influenced significantly by grade, perception of self-level, self-study in majoring and self-study except for majoring(F= 3.33-7.14, p<.05). 2. There were significant correlations between all the predictive variables and the self-directedness(r=.27-48, p<.01). 3. Stepwise multiple regression analysis showed that 35% of the self-directedness in learning of nursing students were significantly explained by self-esteem(23%), locus of control(6%), self-study except for majoring(2 kind, 2%), self study in majoring(good, 2%), and self-study except for majoring( above 3 kind, 2%). Conclusion: Based upon these findings, sociopsychological variables like self-esteem and locus of control are very important factor influencing self-directedness in learning of nursing students.

The purpose of this study is to analyze elementary students' understanding the relationship between perimeter and area in geometric figures. In this study, the questionaries were used. In the survey, the subjects were elementary school students in In-cheon city. They were 86 students of the fifth grade, 86 of the sixth. They were asked to solve the problems which was designed by the researcher and to describe the reasons why they answered like that. Study findings are as following; Students have misbelief about the concept of the relationship between perimeter and area in geometric figures. Therefore, 1 propose the method fur teaching about the relationship between perimeter and area in geometric figures. That is teaching via problem solving.. In teaching via problem solving, problems are valued not only as a purpose fur learning mathematics but also a primary means of doing so. For example, teachers give the problem relating the concepts of area and perimeter using a set of twenty-four square tiles. Students are challenged to determine the number of small tiles needed to make rectangle tables. Using this, students can recognize the concept of the relationship between perimeter and area in geometric figures.

Recently a novel cycle named organic flash cycle (OFC) has been proposed which has improved potential for power generation from low-temperature heat sources. This study carries out thermodynamic performance analysis of OFC using various working fluids for recovery of low-grade heat sources in the form of sensible energy. Special attention is focused on the optimum flash temperature at which the exergy efficiency has the maximum value. Under the optimal conditions with respect to the flash temperature, the thermodynamic performances of important system variables including mass flow ratio, separation ratio, heat addition, specific volume flow rate at turbine exit, and exergy efficiency are thoroughly investigated. Results show that the exergy efficiency has a peak value with respect to the flash temperature and the optimum working fluid which shows the best exergy efficiency varies with the operating conditions.

This work investigates the mechanical properties of conventional concrete (CC) and self compacting concrete (SCC) using fine rubber and silpozz were accompanied by a comparative study between conventional rubberized concrete (CRC) and self compacting rubberized concrete (SCRC). Fine rubber (FR) from scrap tires has replaced the fine aggregate (FA) and Silpozz has been used as a replacement of cement at the proportions of 5, 10 and 15%. Silpozz as a partial replacement of cement in addition of superplasticiser (SP) increases the strength of concrete. Fresh concrete properties such as slump test, compaction factor test for CRC, whereas for SCRC slump flow, $T_{500}$, V-funnel, L-box, U-box, J-ring tests were conducted along with the hardened properties tests like compressive, split tensile and flexural strength test at 7, 28 and 90 days of curing. The durability and microstructural behavior for both CRC and SCRC were investigated. FR used in the present study is 4.75 mm passing with fineness modulus 4.74.M30 grade concrete is used with a mix proportion of 1:1.44:2.91 and w/c ratio as 0.43. The results indicate that as FR quantity increases, workability of both CRC and SCRC decreases. The results also show that the replacement of natural fine aggregate (NFA) with FR particles decreases the compressive strength with the increase of flexural strength observed upto 5% replacement of FR. Also replacement of cement with silpozz resulted enhancement of strength in SCRC.

1. Objective The aim of this study was to survey the adverse reactions by the prescriptions of Soeumin.Soyangin and to compare the tendency of their symptoms according to Sasang constitutional type. 2. Methods The clinical data for this study were based on the medical records of total 91 cases collected from an oriental clinic during 1996-2004. Their constitutional types were diagnosed by a specialist and then confirmed by drug reactions. To evaluate reliability of the analysis, we only analysed the cases above grade C. The target prescriptions were Palmulgunja-tang, Bojungikgi-tang, Hyangsayangwi-tang, Ijung-tang, Hyeongbangsabaek-san, Jeoryeongchajeonja-tang, Yanggyeoksanhwa-tang, Yangdokbaekho-tang and the sorts of Jihwang-tang. 3. Results and Conclusion The prescriptions which were not suitable for their Sasang constitutional type induced indigestion, stomachache and evacuation troubles basically. Besides, the prescriptions of Soeumin caused some fever of the upper body and skin on Taeeumin and Soyangin. And the prescriptions of Soyangin lead to more severe digestive and evacuation troubles on Taeeumin and Soeumin. 4. Conclusion: This study need to be compensated by additional clinical studies which are more systematic and continuous. This way we can make the firm evidence for approving the difference of drug susceptibility according to the Sasang constitutional type.
