The high flowability performance evaluation device for the concrete is the device which was designed to compensate from the incorrect data detection of the viscosimetry examination of the existing concrete. As for the existing concrete viscosimetry method, the measuring data for a viscosity are very irregular by the point of view of an experimenter and a supervisor, Therefore there were some problems to have many different opinions by a small numerical value difference according to the job characteristic. In this paper, we suggested some mechanism to compensate the problem and some driving electronics including the related algorithm, and the communication structure with wireless sensor network between the devices and users are also presented. The effectiveness of the suggested method was verified with a real experiment.

With the women's education level higher and gender equality more promoted, women's opportunity of taking part in business is increasing. Entering the emotional age which counts self-image as being important, there is a view that woman's appearance has a direct relation to their social life. The research is to examine the hypothesis and important factors for women workers at banks for their successful career, that is, to verify the effects of women's appearances on their social life, furthermore, to help female applicants for a bank and the bank clerks have a desirable social life. The subjects were 200 male and 100 female bank clerks and the research was analyzed on the basis of a total of 300 questionnaires. The results are as follows: first, 52 percent of male subjects responded that the factors of "sociability" and "character and good manners" are the most important in social life, while 47 percent of female subjects answered the factor of "ability" is so. Second, 61.5 percent of male and 84 percent of female respondents answered that woman's appearance has a potent influence on their social life. Third, 76 percent of male and 90.9 percent of female respondents answered that when the companies employ woman workers, they take woman's appearance into consideration. It shows even at job interviews that good-looking applicants are in a better position, for bankers must consult with many customers and so their neat and tidy appearance such as their natural make-up and decent hair style (short-hair style) is one of significant factors to perform their jobs. Therefore, appearance managements are primary for women bankers to work at their workplace.

In the object oriented methods, most of the objects are independent from the another. However to get their job done from the system's point of view, they must have some kind of connection established among them. This means that the cooperation among the objects through the interaction is just as important as the static side of the objects. Usually, checking for correctness, compatibility and reasoning of the objects is limited due to the fact that the interactions between the objects are expressed in the form of a line or a box. The reuse experts often claim that the design reuse is more important than code reuse, mostly because it can be applied in more contexts and so is more common. The composition of the objects is also considered as a very important definition in the area of framework which is generally known as a technique to support reuse at both the coding and the designing level. Therefore on this thesis, the composition of such objects has been studied to provide a formal means of evaluating the component's compatibility and better possibility for further improvement in the area of framework, by formalizing the component compositions using the LOTOS.

This study examined the illustrations in the elementary school textbooks which was followed by identifying the parts that displayed gender-discriminating elements or traditional gender roles. The research results are as follows: 1) The ratio of man and woman in the figures appearing in those illustrations was 1.33:1, which means there were more men than women in the illustrations and that there was no balance in the gender distribution among the figures. 2) Male figures were presented as the protagonists in 39.7% of the illustrations, female figures in 25.5%, and both male and female figures in 34.8%. The results indicate that there were much more illustrations in which men were the protagonists than those in which women were. 3) The occupations of the adults in the illustrations were analyzed. As a result, the ratio of man and woman with a job was about 2:1, which implies that there were twice as many male professionals than female ones. Men had over 60 kinds of occupations and women had only 45 kinds of occupations with 59.5% of them concentrated in four jobs including teaching, farming and fishing, doing artistic works, and selling things. 4) The case analysis results of the illustrations in the textbooks demonstrate that the traditional gender roles of a father and mother were followed and that there were gender stereotypes in describing the characteristics of man and woman. Gender dichotomy was observed in the vocations. Men were the leading players in economic, political, and cultural activities, and most of the historical figures were men. Meanwhile, women were depicted as the subjects of economic activities and completely isolated and alienated from political, historical, and cultural activities. It turned out that the figures of the illustrations in the current elementary school textbooks had gender discriminating elements and profoundly reflected the stereotypes for gender roles.

The waterproofing system's performance is known to show a determing by complex interaction of material factors, design details, and the quality of construction, and the waterproofing integrity of waterproofing membranes is determined by the bond to the deck and the amount of damage to the waterproofing membrane. In this research, the basic properties of waterproofing membranes on market and the tensile adhesive chracteristics of waterproofing systems of concrete bridge deck have also been investigated in the view of the damages frequently reported from job site. For the tensile adhesive strength of sheet waterproofing membranes, the results after asphalt concrete paving tends to increase more than before those. The results of the liquid waterproofing membranes are upside-down, and the more concrete has strength, the more strength of tensile adhesive increase. The ambient temperature of asphalt concrete when application of the waterproofing membrane has considerable influence on the performance of waterproofing system. As described above, waterproofing system can be influenced by several factors. If they are not considered under construction, the overlooking will cause the damages of pavement and waterproofing system after traffic opening.

The purpose of this study is to provide diverse points of view to understand the low fertility issue of Korean society. For this phenomenological qualitative study, in-depth interviews were conducted with 14 married couples(28 persons) all raising three children. Participants were asked about overall family and work life, child care role performance, thoughts about child rearing, and their sociocultural context. Interview data were explored based on 6 analyzing steps offered by S, J, Talyor and R. Bogdan(1984). Most participants of this study were formed positive perceptions about having three children. Parents' positive perception was closely related with their attitude of not worrying too much about their children's future as well as child caring contexts around them. Parents' perception about having three children was also linked with their child care role construction process. In detail, parents with more positive perceptions tended to increase their level of child care involvement. This was particularly true for fathers. Mother and father's job situation emerged as an important factor to shape their child care involvement. In addition, child care attitude of people around them explained father's child care involvement. Applying these qualitative results, we first expect to provide detailed ideas about lives with three children in Korea. Second, based on our study findings, a more realistic and helpful policy to help the low fertility problem could be developed. Lastly, we also hope to provide helpful phenomenological qualitative research about low fertility issues of Korea.

Migration studies that assume that decision making is done on an individual basis is overlooking the importance of the family factor. Considering that must people belong to families, it is more appropriate to view migration decision from the perspective of the family. This study analyzes the household migration decision whereby the alternatives are to stay, 10 undertake family migration or to undertake single migration of a member. In developing a conceptual model of household migration decision, it is assumed that the household's objective is to maximize household income which is a function of individual members' earnings. The benefits and costs of household migration and individual migration are identified and the household chooses the migration strategy that maximizes expected household income. When household members have conflicting earning prospects in the potential destination, the household considers single migration of the member with the best earning potentials. However, lone migration by a household member involves cost of family separation which is both monetary and psychic, and this study shows that lone migration is undertaken only when its net gains to the family are greater than the separation cost of the family. The major benefit of choosing single migration is the retention of home base in the place of origin which can serve as an insurance against the uncertainty of obtaining a job in the destination, the benefit that is unavailable in family migration. The conceptual analysis shows how a household's migration decision would depend on its members' economic roles and prospects in the destination. Besides the economic variables, social and life cycle variables of the family translate into separation costs and benefits of migration. This study indicates that one - earner family in low economic status but with good earning prospects and high separation costs is more likely to choose family migration over single migration.

Recently, many companies recognize the individual human resource as a core asset of the corporate value creation and devote a lot of effort to develop and manage competency-based human resource in order to strengthen the corporate competitiveness. As the integrated construction company taking the major portion in Korean construction industry, its construction engineers perform the construction supervision task with various related parties at each stage of the life cycle of the construction project. Therefore, the competency of a construction engineer is an important factor which have a direct impact on the success of the construction project. However, the current capability evaluation scheme of the domestic construction engineers is mainly oriented on the qualification factors such as the certificates or the seniority and this is quite different from evaluating the actual ability for construction management tasks. In this point of view, this study proposes the appropriate level of proficiency in cost management by analyzing the work process and its detailed items of the cost management that is the one of the basic management items of the construction industry. Based on this, this study analyzes the current competency level of the construction engineer by comparing with the required competency of each job position and also performs the engineer's work competency analysis of each work step.

The purpose of the present study is to seek measures to increase the quality of farmers lives by considering the results of a survey on the welfare demand for them when setting up policy. The results are as follows: First, though many concerns and policies to control the rural exodus have been exerted in terms of maintaining agricultural communities, which is one of critical components for the development of Korean agriculture and farming villages, the rural exodus became more and more serious. It is urgently required, therefore, for the Korean administration to correspond actively to the reasons why farmers depart their villages, such as bad prospects, low incomes or problems with their children's education. Second, as the number of females who take part in farming has increased, it is necessary to reform the rural educational environment. In addition, as the agricultural community develops, and other industries flow in, the greater the worries about crime, and consequently, it is necessary to equip a local safety system, share information on job opportunities, and provide educational opportunities. Third, since rural districts nay have financial difficulties because of old-aged and small-sized farmhouse, it is necessary to mainly support the welfare of the aged and lower-income farmers, considering the characteristics of each group and area. Fourth, over half of the farmers responded that they cannot bear to pay the national pension and health insurance premiums, and therefore it should be considered to reduce the pension and premium, or to readjust the insurance value appropriate to the level of the farmer's income. Fifth, despite a number of agricultural policies now in place, farmers desire a policy which can promise a prosperous vision for Korean agriculture and the facilities needed for education and health. It is necessary for the administration to set up policies that are characterized by locality with the view that farmers are not mere recipients, but participants in the policies.
