Purpose: This study was done to develop a pregnancy nutrition knowledge scale and to examine the relationships between pregnancy nutrition knowledge and eating habits in pregnant women. Methods: With convenient sampling, 189 pregnant women who used community health centers for their ante-natal care were recruited. Data were collected using a self administered questionnaire including items on pregnancy nutrition knowledge (18 items) developed by researcher and items on eating habits (14 items). Cronbach's alpha and exploratory factor analysis were examined to test reliability and construct validity of the scale. Pearson's correlation coefficients were used to identify the relationship between pregnancy nutrition knowledge and eating habits. Results: Cronbach's alpha of 18 items was .80. In factor analysis using principal components, 6 factors explained 65% of the total variance. The level of pregnancy nutrition knowledge was not sufficient but correlations between pregnancy nutrition knowledge and some of eating habits were significant. Specifically, pregnancy nutrition knowledge was positively correlated with good eating habits and negatively with bad eating habits. Conclusion: The pregnancy nutrition knowledge scale developed in this study is acceptable for nutrition education led by nurses. Pregnancy nutrition knowledge and eating habits are considered as major variables for ante-natal nutrition education. In future studies, explorations are needed on dietary intake and physiological indices in pregnant women, comparison of women at risk with those not at risk, and development of nutritional education programs for pregnant women.

Nowadays a sense of community based on our community further weakens due to globalization, industrialization, the development of transportation and communication, etc and the community as cultural and psychological units is focused on. In other words, the concept that emphasizes the aspect of 'we' sharing the unique value and goal of community is used. In this current situation, school as an important community organization has been in the spotlight. In particular, college compared with other communities has a special influence on the community. Therefore it is regarded as an important community organization and its importance as part of our efforts to decrease the college students wastage rates continues to grow. The study about school as an important community organization has been conducted actively. However the people in most studies are elementary, middle, and high school students, so there are limitations to what these study findings apply to college. Therefore, this study conducted factor analysis of college sense of community for local college students, categorized it, analyzed the factors having influence on each factor and then looked for suggestions of ways to strengthen college sense of community. According to study, sense of community is categorized into three factors such as 'sense of belonging', 'sense of solidarity', and 'sense of emotional closeness'. After analyzing the factors influencing types of sense of community, factors relevant to them are grades, intimate friends, subjective well-being, community volunteer work, college service satisfaction, and so on.

This study is an attempt to develop the 'Parental Intelligence Scale', which can be applied in the parent education and counselling and provide more useful information for more appropriate interventions by evaluating the characteristics of parent's roles and strong/weak points of the parent's roles under the special situation and environments. In developing the scales, this study reviews of numbers of existing literatures, analysis of scales and tools on parent's role or attitude, collection of episodes on parent's role, validity check processes by field experts, and 2 rounds of factor analysis. The outcomes of the study are as follows; In regard of the development of Parental Intelligence Scale, 3 factors of care-giving role, management role, nurturing role were derived from the conceptual and measurement model. From these 3 factors, 8 sub-factors of empathy, encourage, enhancement, rational authoritativeness, flexibility, rejection, acceptance, control were constructed. 39 question items were derived in order to measure these sub-factors. Especially through the two rounds of factor analysis, the question items with enhanced internal consistency were derived and total cumulative variance was increased, which made theoretical model into the generalized model possible.

The purpose of this study was to determine the level of health promotive behavior of adults and thereby to develope the health promotive behavior scale adjusting our sociocultural situation. The item for health promotive behavior was aquired from statements which was reported by Kim through deep interview with 164 Korean adults. The scale was measured with 4 points Likert type. Data was collected with questionnaire for population living in farm of Chungnam Province and Dae Jon City, from July to August 1994 by research assistant trained by researchers. Data was analysed using SPSS program with Cronbach $\alpha$ and factor analysis. The results are as follows : 1. For the reliability of the scale, Cronbach $\alpha$ was .8264 2. The factor analysis to examine the construct validity showed that health promotive behaviors included 9 factors: health management (16.0%), regular life style(7.4%), psychosomatic control(5.6%), moderation of living(4.6%), stress rnanagement(4.1%), abstain from favorite (3.9%), sanitary habit (3.8%), thought (3.2%), diet habit(3.1%). Nine factors explained 51.7% of varient.

The old city centers of local metropolitans have lost their functions as CBD in korea. Those old city centers have an only role as a gate connected to the new CBD. This study aims to present regeneration stratigies of old city centers through Osaka case study. This research has been focused on the physical and environmental factors in urban regeneration. There are 4 strategies for old city centers. First, the strategy to attract people to the old city centers is high-density and mixed-use development having functions like shopping, entertainment, residence. This kind of development makes local metropolitan cities compact cities to protect urban sprawl. Second, strategy to give old city centers an identity is to conserve traditional culture and structures and to revitalize retail market. Third is to make pedestrian-friendly street system. Osaka ism't pedestrian friendly but remodelling the connect the pedestrian path to the culture facilities. Fourth is to have water and green environment. Green space is the strong factor that pull people to old city centers.

The chargers for DC power supply of the contro1lers, which have been installed in the relay rooms in 345/154kV substations of KEPCO, lag in both aspects of technique and performance. Moreover, as they are SCR-based, they dont meet the performance requirements of todays digital and automated controllers. Now two controllers are running in pair and one of those is for reservation. There are lots of troubles because the patrol engineering team has to replace them manually whenever they are out of order. So it is expected to bring convenience if the charger replacement is automated. Also, the existing chargers take much space, weight and cost - which have increased the need of development to make them smaller, less expensive, and have high quality. We will develop a charger system which has one fifth of the weight of the existing system by double-integrating the volume. The new system will be ready for a future full unmanned system with integrated pores for remote control, state-of-the-art digital features, and more than 90% efficiency/power factor against 80% efficiency/power factor of the existing system.

The purpose of this study was the development of a scale to assess daily hassles coping behaviors for school aged children. The subjects were 398 children consisted of 197 3rd grade an 201 6th grade. They were selected from elementary school in Seoul, InCheon, DaeJeon, GwangJu and Pusan(202 males and 196 females) A questionnaire as the methodological instrument composed of 65-item daily hassles coping scale, demographic questions, 27-item Children's Depression Inventory and 20-item Locus of Control Scale. Statistics such as mean, %, X2, Cramer's V, Cronbach's α, factor analysis and Person's γ was used for used data analysis. The major findings of this study were as follows; 1)55 items of the 65-item scale were selected through item discriminant method. The discriminant coeffcients of the items(Cramer's V) ranged from .35 to .68. 2)5 factors were extracted from the 1st and the 2nd factor analysis. The subscales labelled 'active' 'passive' 'aggressive' 'avoidant' and 'social support seeking' coping. The criterion validity of this scale was assessed by computing the correlation measures of Children's Depression Inventory and Locus of Control Scale with this scale. Most coefficients were significant(ranging from r=-.16 to r=.40,p<.01,p<.001), although their correlations were modest. 3)Finally, the internal consistency of this scale appeared to be at an acceptable level(Cronbach's α=.90)

The purpose of this study is to evaluate the future potential value of CTE(Critical Technology Element)s that are evaluated to be low in TRA(Technology Readiness Assesment) and to present investment prioritization technologies in defense R&D(Research and Development) based on them. To do this, we used the DEA(Data Envelopment Analysis) method, which is useful in evaluating the efficiency of the organization. Specifically, we suggest a systematic framework to evaluate the future value of CTEs by setting the CTEs derived from the TRA process to DMU(Decision Making Unit)s, the cost and time required to develop each CTE as the input factor of the DEA and the effects of the development of each CTE as the output factor of the DEA respectively. We also conducted an illustrative case study on radar technologies to demonstrate the usefulness of the proposed approach.

In this study, instruments were developed to measure of mathematics attitudes by conceptualization of epistemological beliefs as a cognitive dimension, mindfulness as a conative dimension, affect as an affective dimension. Perry's epistemological development scheme and Langer's mindfulness theory was noticed as a theoretical approach. Exploratory factor and confirmatory factor analyses, and a reliability test were assessed. This article suggest a new framework for analysing attitudes toward mathematics and changes in attitudes toward mathematics.
