In Korea home economics in the secondary school level was only taught to girls until 1995. So. home economics education only for girls was criticized to sexist education by the feminists. According to the 6th revision of curriculum. home economics has been taught to girls and boys. But some of curriculum developers raises another questions on home economics education. They argue that home economics is a subject which prepares students for the demand of their day-to-day lives. but they can manage their lives well without school learning. The purpose of this study is to explore the educational values of home economics in secondary education from the gender-sensitive approach. For this study, a literature survey on the nature of home economic education in secondary education and the content analysis on 12 secondary school textbooks of Home Economics were employed. The results are as follows : First, the educational values of home economics education should not be underestimated. The aims of home economics education is to help students grew into a independent person by managing their daily lives. The home is charged with fostering a side of our life which we might call Personal, private. intimate and nurturing. The management of the home needs good skills and attitudes. and many knowledges on the child rearing, family relation, marriage, love and sex, which can not be successfully acquired without school learning. And home economics education for boys and girls can help break down the barriers between the sexes because it can change the attitudes of students regarding the private sphere. which is traditionally where women have worked. Second. most of contents of Home Economics were composed of the women-oriented contents. There was a trend still describing that domestic labor mainly be carried out by mother. And the ideas that only the family consisting of two parents and their children is normal were founded. Finally directions of development of the Home Economics Education are suggested.

As the bearing wall structure, which has been widely applied to domestic apartment buildings since the 1980s, cause many problems during remodeling of buildings, the government encourages constructors to adopt flat plate or rahmen structure through legal incentives. In line with such a trend, the green frame, an eco-friendly rahmen structure that has removed the shortcomings of previous structures, was developed to enhance structural safety, constructability, and eco-friendliness. The construction of green frame can reduce the labor cost and facilitate the composition of iron bars to reduce rebar loss through calculating the quality and establishing the bar bending schedule automatically on the precast concrete member data collected over the design phase. Therefore, the purpose of this study is to develop the algorithm to automate the calculation of iron bar volume for the green frame designed on composite precast concrete members. Automated algorithm to calculate concrete structural design information and design information. Practices through the application site should prove efficacy. The database established by the developed algorithm will automate the establishment of iron bar processing map and bar cutting list and the calculation of optimal composition and order volume to minimize the rebar loss. This will also reduce the expenses on management staff and overall construction cost through the minimization of rebar loss.

The project management information system (PMIS) has recently been developed by using the information technology(IT) in order to implement advanced information management technology to construction industry in Korea. The PMIS has been applied not only to domestic construction projects, but also to some overseas projects executed by Korean construction companies. This study was performed to develop the PMIS that is tailored to the US construction IT market. It has been monopolized by the US-based IT companies, but other companies are recently emerging with competitive technology and market strategy. As a preceding study, existing commercially available systems were analyzed, and the required features of the PMIS were identified by analyzing the core elements of contract, process and cost management about construction projects in the US. Then, the PMIS was developed based on the aforementioned analysis results. The system includes the document management module with an internal electronic approval system, the cost-plus-based automatic labor cost calculation module, and the progress management module to support the integrated project cost management. In addition, the functionality of the developed system was verified by experts about construction management in the US via questionnaire survey. The developed PMIS, in this study, is expected to be applied not only to the US construction IT market as a system specialized for the US construction industry, but also to other oversea markets in the future.

Due to the improvement of living standards and avoidance of the 3D industry, it is difficult to find young and competent domestic workers at construction sites, and most foreign workers are contributing to the replacement, but the quality is still deteriorating due to lack of skilled workers and aging. Precast method is a method that make members in factory and assembles them on site, which can be expected to improve labor force and quality. This study is intended to provide basic data for the development of hang-type PC beams that can be applied to the determination of the field application of developed PC beams. The U-type connecting material is installed on both ends of the hang-up PC beam, and the role of the U-type connecting material is very important because it is a simple construction method through the U-type connecting material. In addition, the performance of the U-type connecting material will determine the performance of the hang-type PC beam as the final destruction occurs in the hang-type PC beam. The material properties of U-type connecting material were identified through structural experiments, and the end test corresponding to the partial experiment was conducted based on the material test results identified. Finally, the final design value of PC beams was proposed through structural experiments for application to the site.

Although international construction market gradually takes a important position among the export industries, the previous studies about international construction entry strategy have just focussed on trend investigation or suggestion for revitalization. Moreover, in order to prepare the market uncertainty such as world financial crisis and to plan the long term strategy, specific strategy studies based on corporate level are required. Therefore, this study estimates the nine strategic index and four financial index of 31 companies that performed 1920 international projects from 1993 to 2007 and evaluate the performance as three periods by multi-regression analysis. Also, this study analyze dynamic correlation between these index and the performance considering times. this study verifies that market diversification, product diversification, localization and decrease of debt to asset ratio make a good effect on the international order as long term strategy and shows that collaborated entry with domestic corporations, alliance entry with host country's company, alliance entry with third country's company, portion of labor cost and portion of management expense differently make a influence on the performance as times. these results will be helpful for the construction companies to plan the international entry strategy reasonably and specifically.

The purpose of this study to analyze the regional competitiveness of the part material industry in Korea. According to the analysis, there was an empirical regional difference in the part material industry in Korea: in the Seoul Metropolitan Area, the industrial scale was found to be relatively small, although many companies were observed to be in the growing stage; in the Chungcheong region, it was estimated that the industrial scale is large, and many companies were found to have already reached the maturation stage with high growth rates; and in Honam and Jeju, Daekyung and Gangwon, and Dongnam, although the scale of the part material industry was found to be large, many companies were observed to be in the declining stage with low growth rates. This study also conducted an analysis based on LQ (Location Quotient) and RLQ (Relative efficiency of Labor Quotient). The analysis showed that industrial policies regarding workforce planning and industrial restructuring should focus on improving the productivity of the entire part material industry. Lastly, this study examined the competitive part material industry for the five regions by analyzing the RCC (Regional Competition Component). The findings of this study will be helpful in exploring ways to support the domestic part material industries in each region.
The purpose of the research is to explore the main cause and effect of successful marriage that Korean husbands, who are multicultural families had. To do the research, the experiment has been done with 7 husbands for 2 months. The 7 husbands took depths interview and analyzed the result by grounded theory approach. As a result, the husband experienced 'repentance of marriage' because of 'unready marriage', but 'Raising children', 'Helping housework' and 'recognition from friends and colleague' have affected the husbands to have a successful marriage adaptation. Based on the result, a political and practical proposal has been proposed to the Korean husbands who are multi-cultural family. Here are the examples of the proposal. As a social welfare policy, 'obligation of information offering for prospective spouse', 'following the Labor Standards and parental leave', 'expansion of visiting supervise system' and 'making guidance for husbands and distribute map of Immigration Office, Multicultural Family Support Center and Community Center' have proposed. And as an alternative plan for a practical social welfare policy and continuous social awareness improvement, 'various education program', 'a program with domestic married couple', 'a program with parents-in-law', 'a specific program to increase the housework participation for husbands' and necessity of development and practice of group program for husband have been emphasized.

Recently, Domestic public construction projects are experiencing a great deal of disputes because of the growing uncertainty about the criteria for calculating the prolongation cost. In addition, researchers have been studying various systems and proper cost estimates in an effort to reduce the uncertainty of these systems and the occurrence of disputes. However, there is no standard yet for social consensus. Meanwhile, The study on the classification system according to the recognition standard of accounting has been systematically studied. As a result, the concepts of accrual and cash basis are defined separately. The purpose of this study is to verify the possibility of applying the concept of 'accrual basis' to the Standard for calculation of prolongation cost. Therefore, As a result of analyzing the occurrence pattern of Job-site overhead cost, it is confirmed that actual costs can not be calculated by the cash-basis method. In particular, the implications of the necessity of the accrual-basis method should be more strictly indicated in the case of items such as indirect labor costs and welfare benefits. In addition, the contractor 's claim report and the appraisal report were examined. As a result, it was confirmed that the calculation situations of prolongation costs are biased to the cash-basis method. In this way, it is suggested that necessary to supplement the calculation standard of the actual costs from the point of view of accrual basis.

Since microalgae research started on late 18 century, they have been recognized as one of the most important bioresources used in bioindustry. Owing to the large efforts paid to industrial application of this microorganisms, their importance on food/feed and bioactive compounds has been further extending into the environmental research areas including alternative energy resources, mitigation of the carbon emission, and waste-water treatment. However, despite the importance on their industrial application, the fundamental research field related to the long-term preservation of microalgae culture has not received much attention. However, a less labor intensive and cost-efficient preservation technology enabling biologically active and stable microalgae-culture provides a key success factor in the biotechnological application. Therefore, this study investigated various cutting-edge microalgae cryopreservation technologies currently developed so far, mainly targeting Chlorophyta, which occupies the largest taxon in the classification system of microalgae. In addition, for the development of successful cryopreservation technique, the key factors such as temperature control effect and preservative effect during cryopreservation of microalgae culture were investigated. In addition, the problems with current preservation technology that is being used in Korean domestic biological resource banks and the international microalgal resource banks are described. According to our investigation, currently no standard method for long-term preservation of microalgae is available due to their various morphological and physiological characteristics. To overcome such issues, much more efforts on fundamental research area on the identification of specific biomarker used for microalgae taxonomical classification and further systemic approaches based on strain-specific cryopreservation methods needed.
