Iron deficiency anemia in pregnant women has been of great concern because of its negative effects on the outcomes of pregnancy. Much of evidence has shown that there are associations between pregnancy outcomes and maternal iron status. Maternal iron status might affect pregnancy outcomes through the iron status of the cord blood. In this study, we divided 91 subjects into two groups : the anemic and the normal groups. The groups were classified according to their hemoglobin(Hb) and hematocrit(Hct) values of the maternal blood in the third trimester of the pregnancies. We determined the parameters for the iron status of the cord blood and then analyzed the correlations between these parameters and the pregnancy outcomes. Mothers in the anemic group had a significantly higher parity number and a lower dietary score as well as a shorter duration of iron supplements consumed compared to those in the normal group. Maternal Hb values in the third trimester had positive correlations with the infant's head and chest circumferences, and the Hct values related positively to the infant's chest circumferences. On the other hand, Hb concentrations of the cord blood had positive correlations with the infant's height and head and chest circumferences. The Hct values of the cord blood had positive correlations with gestational periods and the cord lengths. These results suggest that the maternal iron status might influence fetal development through the iron status of the cord blood.

The objective of this study was to investigate the effects of cell status of BOEC on development of bovine IVM/IVF embryos and gene expression in BOEC before or after culturing of embryos. The developmental rates beyond morula stage in the BOEC co-culture group was significantly higher than in the control group (p<0.05). In particular, blastocyst production in the BOEC co-culture group (28.3%) was dramatically increased compared with the control group (7.2%). In the in vitro development of bovine IVM/IVF embryos according to cell status, the developmental rates beyond morula stage in the primary culture cell (PCC) co-culture group were the highest of all experimental groups. Expression of genes related to growth (TGF-${\beta}$ EGF and IGFBP), apoptosis (Bax, Caspase-3 and p53) and antioxidation (CuZnSOD, MnSOD, Catalase and GPx) in different status cells of BOEC for embryo culture was detected by RT-PCR. While EGF gene was detected in isolated fresh cells (IFC) and PCC, TGF-${\beta}$ and IGFBP were found in IFC or PCC after use in the embryo culture, respectively. Caspase-3 and Bax genes were detected in all experimental groups regardless of whether the BOEC was used or not used in the embryo culture. However, p53 gene was found in IFC of both conditions for embryo culture and in frozen/thawed culture cells (FPCC) after use in the embryo culture. Although antioxidant genes examined were detected in all experimental groups before using for the embryo culture, these genes were not detected after use. This study indicated that the BOEC co-culture system used for in vitro culture of bovine IVF embryos can increase the developmental rates, and cell generations and status of BOEC might affect the in vitro development of bovine embryos. The BOEC monolayer used in the embryo culture did not express the growth factors (TGF-${\beta}$ and EGF) and enzymatic antioxidant genes, thereby improving embryo development in vitro.

The purpose of this study is to present the overall landscape of Comparative Education study in teacher training program at universities in Korea. The Comparative Education in Korea is relatively young without a lengthy tail on its name and still on the way of upgrading itself, however various efforts are gathering for the development of Comparative Education. With this understanding, this paper diagnoses the current status of Comparative Education in Korea by analyzing 1) the number of institutions which provide Comparative Education lectures for their teacher training program, 2) aims of Comparative Education teaching, 3) curricular and course titles, 4) teaching methods and textbooks, and 5) current issues and problems currently laid on Comparative Education in Korea designated by actual lecturers and professors who are in charge of Comparative Education lectures. The historical development of Comparative Education in Korea will be briefly presented at the beginning part of the chapter. To gauge the comparative position of Korean Comparative Education, the second half of this paper introduces the cases of Comparative Education at universities worldwide, presenting various countries' status of Comparative Education along with their developmental status. As the first research which pays an attention on the current figure of Comparative Education in Korea, it will form an impetus on why we should teach college students about comparative education and on what next step should be carried for further development of Comparative Education at universities based on the comparative understanding of other countries. Since it is in the transitional stage in terms of its development, it would be critical to have a self-analysis of the current status, which will help to lay the comprehensive understanding background for designating the future direction of its development.

The purpose of this study is to analyze and evaluate the role and merits and demerits of insurance agencies, which are the main sales channels of the domestic insurance market, from a neutral standpoint, and to present a roadmap by finding ways and tasks for the sustainable development of the insurance agency industry. Recently, criticisms and regulations on independent distribution channels have been strengthened due to deterioration in growth potential and profitability, and increase in civil complaints of insurance companies. In the 2000s, as the center of insurance sales channels shifted to GA and bancassurance, the supervisory authorities regarded the irrationality of project costs and recruitment fees as the root causes and announced a regulatory improvement plan. In view of these circumstance, the operating status, problems of domestic insurance agencies and their contribution to the insurance industry were reviewed. In addition, we tried to find a mid-to-long term development plan by analyzing the case of insurance agency operation in Japan. This study identified the operating status and contribution of insurance agencies in South Korea, and focused on the major status of the Japanese insurance agency industry, ways to improve management efficiency, and the status and role of self-regulatory organizations for insurance agencies. Based on this, it was proposed to improve the professionalism of the sales organization, introduce a company specializing in insurance sales, and to strengthen the status of the association of the insurance agency as for the development plan of the insurance agency industry in South Korea.

This study documented and diagnosed the status and problems of coastal dredging and offshore disposal of dredged sediments in South Korea to improve assessment procedures for marine environmental impacts and develop effective management systems. A total of $729({\times}10^6)m^3$ of coastal sediment was dredged in the harbors during the period of 2001-2008. Most of dredged sediment was disposed to the land dumping sites whereas ocean disposal accounted for less than 5%. Ocean disposal areas were especially concentrated to the exclusive economic zone (EEZ) in the southeast of Busan, which is not only an important fishing area for fishermen, but also considered to be spawning and nursery ground for some commercial fish species. To minimize negative impacts of dredging and ocean disposal of coastal sediment on marine ecosystem and potential strife among coastal users, we suggest 1) in development projects involving ocean disposal, it should be mandatory to propose careful reuse plans in the land, and 2) guidelines of environmental assessment and consequence management programs should be developed and implemented.

This paper focuses on how Singapore has adopted the 'Marriage Promotion Policy' for resolving the low birthrate and how it has been using the Social Development Network (SDN) to cope with the problem of low fertility. Social Development Network is an organization that shows Singapore's national stewardship to marriage, and has developed from the beginning to the social phenomenon of increasing number of highly educated women and decreasing fertility. The predecessor of Social Development Network is 'Social Development Unit' (SDU), absorbed the 'Social Development Service' (SDS) that was launched later, and reborn as Social Development Network in 2009. At its inception, Social Development Network has been recruiting and organizing its own memberships without the help of commercial marriage agencies, and since 2006 has been dedicated to delegating dating and matchmaking services to private companies and supporting projects. The purpose of this paper using literature analysis is to analyze the status and role of Social Development Network from the theoretical point of view of marital stewardship to the present, and to suggest meaningful implications for Korea which has the same social experience.
