Opens the construction market recently, the construction industry of Korea has faced up to the barrier of globalism, and has been enforced to follow the various global standards in many aspects. Accordingly, it is expected that the test method related to the cement and concrete will be changed to conform to the international standards in Korea. Therefore, in this study, the strength tests are executed for the cement mortars, made by KS and ISO standards respectively, and then obtains such results. 1) The flow of the cement mortar according to ISO is about 8% higher ,than that of KS. 2) The flexural strength of the cement mortar according to ISO is about 10~20% higher than that of KS, and the compressive strength is about 30% higher. 3) The compressive strength relation between the cement mortars of KS and ISO may be expressed in the first-order recurrence formula as follows: Y = 1.33X - 8 In which X is the compressive strength(kgf/$\textrm{cm}^2$) of the mortar according to KS and Y is the compressive strength(kgf/$\textrm{cm}^2$) of the mortar according to ISO.

성인의 혈청 Ascorbic Acid 및 Cholesterol의 정상치를 정하고, 이들간의 상관관계 존재여부를 밝히기 위해 32명의 남 녀 대학생 (각 16명)을 대상으로 하여 연구한 결과, 여학생의 경우에 혈청 Ascorbic Acid 는 남학생보다 약간 높아서 $3.1{\pm}0.68mg/100ml$였고 Cholesterol은 상당히 낮아서(위험률 5%) $190{\pm}20.4mg/100ml$였다. 남학생의 경우에는 각각 $2.8{\pm}0.66mg/100ml$, $202{\pm}14.9mg/100ml$였다. 이 두가지 측정치 사이에는 위험률 5%로써 음(除)의 상관관계가 있다고 말할 수 있으며, 그 상관계수는 -0.36이였다. 즉, Ascorbic Acid의 충분한 성취는 혈청 cholesterol을 낮출 수 있다고 생각된다.

This study examines how full-time housewives manage family resources, make decisions, handle pressures, and negotiate the constraints of everyday life in a society that places unrealistic expectations upon them. We approached housewives with an assumption that they are individuals who think, strategize, and solve problems. We also imagined that they are capable of speaking for themselves and making choices under situational and personal limits. Eleven full-time housewives were interviewed on how they experience their marriage, child (or children), family, and society. Their narratives were then analyzed to sort out the strategies the women employ to maintain their identities. The narratives demonstrate the women's will and agency as they work to resolve the contradictions from their daily life, and reveal individual differences in their midst, despite the fact that they had been often considered homogeneous.

To evaluate the effect of disinfectants for Alginate impression, several commercially available disinfectants were tested to Alginate model contaminated by Methicillin resistant Staphylococcus aureus. Alginate specimens were artificially contaminated by Staphylococcus aureus and soaking in four commercially available disinfectants for 1, 5, 10 minutes and colonies were counted for each case. Significant reduction of bacterial colony counts was noted after soaking in 0.5% and 0.05% sodium hypochlorite and after soaking in 2% glutaraldehyde, but not after soaking in Hypochlorus add. Commercially available sodium hypochlorite and glutaraldehyde were found to be effective disinfectants for Alginate impression. But hypochlorus add was not adequate disinfectant.

Rapid social change in economy, society and information technology takes the initiative of changing office formation. It also requires new change in workspace function for the office workers. This research is about the change of office formation chronologically according to the change in economy, society and cultural diversity. The study also shows the directions for the workspace design considering the new demand and flow of the new office formation. Mobile Office, Virtual Office and Moduler Office are the new office formation. Also, the new workspace requires the common space where the workers can communicate diversely and share their knowledge and ideas, enhancing collaboration and productivity of the new workspace.

This study was conducted to provide a foundation for housewife-consumer education programs appropriate in the information society. For this purpose, the authors reviewed existing literature, analysed consumer counseling cases, and conducted focus group interviews. The need for housewife-consumer education was illustrated, and desirable educational contents and methods were proposed. The existing housewife-consumer education programs did not work effectively because the contents were too general, and mostly structured with non-interactive one-way lectures. More effective programs should be designed to accomodate the educational purpose and contents which fitted with the specific needs of housewives as the representatives of the family consumer units. It should also take the family life cycle stages into consideration. The education programs would work better when they were oriented more toward actively participating, locally-based spontaneous small-groups.

As the Internet users are growing, GIS researchers that would like to integrate various GIS informations have more interests for information searching technologies based on Web. But, even though these researches is growing a infinite possibility of utilizing the map, there are not yet providing more functionalized GIS services. This paper proposes a searching mechanism for the teacher information based on the SVG(Scalable Vector Graphics) format transformed the SHP format. We also implement the home-page link function inserted Web-connection information of the specific locations that could connect specific school web site within SVG file. We also provide the services to interpret requested query with proposed scheme.

This qualitative case study focused on the activation plan of flexible work arrangements. We selected eight workers from a foreign affiliated firm that has various flexible work arrangements for in-depth interview and focus group interview. The workers were categorized into two groups; those who have experiences with flexible working and those who have needs for flexible working. We analyzed their condition of work-family life and experiences with flexible working. Through the focus group interview, we can find out the needs and suggestions about activation plans of flexible work arrangements.

This study investigated various alternatives for childcare among dual-earner families and discussed implications for public policy development. Eight employed married women and two of their husbands were interviewed about work-family balance. All the interviewees complained that taking cue of the children in dual-earner families is a challenge. They resort to all available alternatives because public childcare support is insufficient and inadequate. There were five different types chilcare: extended family network, public and private institutions, paid help (nannies), rearranging work schedules, and training their children to take cue of themselves. However, all these alternatives entail various problems. More and better childcare facilities and programs should be built and after-school programs should be designed. On the other hand, parents should also make more effort to prioritize children's needs in finding a balance between work and family.
