This study is a investigation research to examine total 123 children's thought, perception and coping method about measles, with 62 children who had experienced the measles and 61 good health children in the school, which had spread to a primary school in kyoungsang-bukdo province. The data collection was done from December 6 to December 8. The analysis of data was SPSS(10.0) for descriptive statistics. The data were collected from total 123 children, 62 of them who had diagnosed measles on October, 2000, when the measles had ended, were used a purposive sampling, the others who had a good health were used a convenience sampling. From three to six grade students made out directly the questionaire in the way of self-questionaire, and from one to two grade students, made out answering the question which the researcher had read the items. The researchers call back the students to complement the contents about the items inadequate answers, so they raised the reliability. The results were as follows. 1. The results of observe carefully the measles infection degree by a sex, the boys(27.4%) were sick severely compared with girls(9.7%)were sick weakly compared with the boys(27.4%)(p〈0.01). 2. The 62.9 percents of infected children by measles thought that they were infected at school, regarded the doctors as a first judge, and had caught the measles because of their fault. The results of observe carefully, 33.8 percents children of infected by measles had have a secondary vaccination. To the question whether they go to institute or not while suffering from the measles, 35.5% children didn't go there since they had heard the fact they infected the measles. 3. To a question of asking if close mend caught the measles, what will they do, 65.1% children of caught the measles answer ‘I can't meet my friend'(p〈0.001). It was significant that infected children have more interests than didn't infected children. The 22% children of didn't catch the measles take great interested in health compare with the 12.2% children of infected the measles(p〈0.05). To the question if they listen the preservation of health broadcasting, 63.4% children answer ‘I listen well’. It was significant between the infected group and didn't infect group(p〈0.05). To the question if they delivery to the written information at home, it was significant between the infected group and didn't infect group(p〈0.05). 4. The infected group of 69.1% children think the health is most important in their life school than any other they like study.

Objective : The main purpose of this study was to analyze factors affecting a health related quality of life(HRQOL) in the elderly stroke patients with(Group 1) or without(Group 2) sequela. Methods : This survey performed secondary analysis with 'the fifth korea national health and nutrition examination survey', and investigated 91 elderly stroke patients over 65 years. Results : The results were as followed: HRQOL and self rated health had a significantly lower in Group 1(p<.05). In all groups, HRQOL was affected by self rated health(${\beta}=0.39$), mental health, and medical health significantly(p<.05). In group 1, HRQOL was affected by mental health(${\beta}=0.45$), self rated health significantly(p<.05). In group 2, HRQOL was affected by medical health(${\beta}=0.45$), functional health, mental health significantly(p<.05). Conclusion : In order to improve the HRQOL of stroke patients during rehabilitative therapy, it is important that early detection and early intervention of depression and suicide, which affect mental health status, are important in the case of severe aftereffects. If the patient continues to support his/her current status regardless of aftereffects, he/she can improve the HRQOL with functional recovery of the stroke patient, and finally have a positive effect on the independence of the stroke patients.
This study observed particulate matter ($PM_{2.5}$ and $PM_{10}$) in the downtown area of Jeju City, South Korea, to understand the chemical composition of particulates based on an analysis of the water-soluble ionic species contained in the particles. The mass fraction of the ionic species in the sampled $PM_{10}$ and $PM_{2.5}$ was 44.3% and 42.2%, respectively. In contrast, in Daegu City and Suwon City, the mass fraction of the ionic species in $PM_{2.5}$ was higher than that in $PM_{10}$. The chloride depletion percentage of $PM_{10}$ and $PM_{2.5}$ in Jeju City was higher than 61% and 66%, respectively. The contribution of sea-salt to the mass of $PM_{10}$ (5.9%) and $PM_{2.5}$ (2.6%) in Jeju City was similar to that in several coastal regions of South Korea. The mass ratio of $Cl^-$ to $Na^+$ in the downtown area of Jeju City was comparable to that in some coastal regions, such as the Gosan Area of Jeju Island, Deokjeok Island, and Taean City. The mass fraction of sea-salt in $PM_{10}$ and $PM_{2.5}$ was very low, and the concentration of sodium and chloride ions in $PM_{10}$ was not correlated with those in $PM_{2.5}$ ($R^2$ < 0.2), suggesting that the effects of sea-salt on the formation of particulate matter in Jeju City might be insignificant. The relationship between $NH_4{^+}$ and several anions such as $SO_4{^{2-}}$, $NO_3{^-}$, and $Cl^-$, as well as the relationship between the measurement and calculation of ammonium ion concentration, suggested that sea-salts may not react with $H_2SO_4$, and $(NH_4)_2SO_4$ may be a major secondary inorganic aerosol component of $PM_{2.5}$ and $PM_{10}$ in Jeju City.

Foreign direct investment (FDI) by firms has various motives in terms of the strategy for firms' long-term growth. This research uses the case study of Hyundai Motor Manufacturing Alabama to analyze the motives of the Korean auto industry's FDI in the U.S. and the locational factors that determined the selection of the site. This paper starts from the question of why Hyundai made the decision to invest in the U.S., which is not favorable in terms of production cost, especially considering that its exports to the U.S. have been on the increase. The results indicate that the strongest motive for the decision to invest in the U.S. was to ameliorate the trade friction between Korea and the U.S. Given that Hyundai depends on the U.S. market to a large extent for its exports, the foremost motive was to use local production in order to reduce the serious trade imbalance in the automobile sector between Korea and the U.S. in order that trade friction with the U.S. may be avoided and causes for trade disputes may be reduced. Other motives such as improving the access to local consumers were of secondary importance. After the selection of the country in which to invest, however, various factors were considered in the decision regarding the location of the plant, and incentives by local governments ultimately played a key role in this decision. The results imply that the Korean manufacturing industry's investment in the U.S. cannot be explained by traditional FDI theories and instead was greatly driven by a strategic defensive motive. In addition, the results confirm that the design of an appropriate incentive structure by host governments is important for attracting FDI.
In this study, it can be shortened tunnel construction work period by introducing a single-shell tunnel does not placing the secondary concrete lining, a global research trend, reduction of the cost of the lining placement and number of benefits that can ensure the safety of long-term tunnel with a single shell it was to study the tunnel method. First, we analyze the design and construction practices relating to delete lining of the domestic design and construction practices and a comprehensive analysis of the stability study found a rock in good condition interval (1~3 grades), we propose that the lining uninstalled. In the case of domestic changes on the ground floor is very heavy underfoot conditions many so tunneling method by single shell as ground conditions are good and one preferred the water points that apply in less soil, the soil health and poor sections (4~5 grades) reflecting with respect to the concrete lining that is expected reasonable.

This study conducted a series of studies to offer a novel method of using CBS-dust that produced as by-product in the manufacture of cement. Four different contents of BS and CBS-dust were adopted for test parameters of this study. Mortar with 50% of W/B was fabricated. First, in the case of the fresh mortar, the flow decreased as the CBS-dust replacement rate increased, but the binder composition ratio BS 45% and 65% showed higher fl ow than Pl ain when repl acing CBS-dust 5%. In the case of air content, overall, the tendency was proportional to the CBS-dust replacement rate, and chloride tended to exceed the reference value at all replacement rates except for the CBS-dust 0% replacement. The compressive strength of the hardened mortar shows the resul t that the strength is improved when the CBS-dust is repl aced by 5% to 10%, and the CSH gel and structure formation is confirmed by microstructure analysis through the hydration reaction when the CBS-dust is replaced. Therefore, for a given condition CBS-dust is used as a early-strength admixture in a concrete secondary product that uses a large amount of admixture without reinforcing bars it can be an effective method for enhancing the strength of concrete as an alkali activator.
The study aims to compare our newest mathematics curriculum with Singapore's and analyse the differences of them. Because the levels of our mathematics education have been evaluated to be difficult to our students, we try to find that the evaluation is appropriate and there are other characteristics we have to notice carefully, and provide some implications for our mathematics curriculum. We mainly compared both mathematics curriculums focussed on the national documents of mathematics curriculum, and textbooks in the level of middle school. The results are following. Firstly, Singapore has three tracks based on students' abilities and there are three kinds of textbooks on the tracks. This is a different from our teaching on students level. Secondly, the introductions of our mathematics curriculum contents are not faster than Singapore's, but they have more concrete ranges of contents than us. Thirdly, the focus of Singapore's mathematics education lies on problem solving, and we can find some good examples of contents of textbook focussed on problem solving. Some mathematical concepts are introduced simply without any process of students discoveries or investigations, and the focus lies on the problem solving using the concepts. Fourthly, Singapore's mathematics textbooks are more emphasis on the internal connections than ours.
Value is an intellectual and an affective concept that influences behavior. It does not exist individually but is conveyed through generation with some system. Korean students showed high achievement scores in spite of low emotion in mathematics learning. The objects of value recognition ought to be extended to social value as well as mathematics for balancing intellectual and affective features. Since the value formed at the first step in mathematics learning keeps its influence even after learning, it is important to form a positive recognition in the value. The following conclusions were drawn. First, the mathematics learning value instrument developed in this study. It is appropriate to explain a students' imbalance of intellectual and affective characteristics. Second, it is possible that the intellectual achievement of Korean students are influenced by the others-oriented value in particular. Third, the recognition of the mathematics learning value of elementary school students would have an influence on secondary school learning. Therefore, education for parents of elementary school students is required. This study can provide a basis on the view of the mathematics learning value which influences the educational result of Korean elementary students as well. It is expected from the following studies that focus on improving affective characteristics on mathematics learning of Korean students is beneficial.
The purpose of this study is to develop a mobile-based math learning application and explore its application. In order to develop a learning application, the present study included literature review on math education involving mobile learning, investigation of literature related to mathematics education conducted in a digital environment, and method of use and implementation environment of existing math learning applications by type. Based on these preliminary investigation and analysis, an android version application, 'Mathematics Classroom for Middle School 3rd Graders' was developed. This application can be used for learning units such as Quadratic Functions and Graphs, Representative Value, and Variance and Standard Deviation. For the unit on Quadratic Functions and Graphs, the application was constructed so that students can draw various graphs by using the graphic mode and discuss their work with other students in the chatting room. For the unit on Representative Value, the application was constructed with the mathematical concept of representative value explained through animation along with activities of grouping data acquired after playing archery games by points or arranging them according to size so that students can study when and how to use median value, mode, and average. The application for Variance and Standard Deviation unit was also constructed in a way that allowed students to study the concept of variance and standard deviation and solve the problems on their own. The results of this study can be used as teaching & learning materials customized for individual student in math classes and will provide anyone the opportunity to engage in an interesting self-directed learning of math at anytime. Developed in the format of real life study, the application will contribute to helping students develop a positive attitude about math.
