This study examined the role of maternal attribution in parenting behaviors of mothers who have a child with developmental disabilities. Using an attributional model, it assessed whether maternal attributions about the child's knowledge, capacity, expectation, and responsibility for behavior problems have effects on maternal behaviors of affect, authoritarian control, and overprotect. The sample consisted of 161 mothers of elementary children with developmental disabilities. Multivariate regression analysis revealed that maternal attribution about the child's capacity for misbehavior had positive influence on maternal affect and negative influence on authoritarian control behaviors, and that maternal attribution of responsibility for misbehavior positively influenced maternal authoritarian control and overprotect behaviors. Also, maternal attribution about the child's knowledge for misbehavior had negative influence on maternal overprotect behaviors. In addition, such background factors as number of disability, maternal education, and job of mother were significant predictors for maternal attribution, while maternal self-esteem was a strong significant predictor for mothering behaviors. The findings suggest the importance of maternal attributions in parenting.

In order to investigate the role of nuclei and cytoplasm in early embryogenesis, interspecific nuclear transplantation was carried out Nuclei of one species of amphibian was transplanted into enucleated egg of another species. In interspecific hybrids between Rana species, development was arrested before or right after the dorsal lip formation. In intergenetic hybrids between Rana, Xenopus and axolod, developmental arrest took place at late blastula stage. Comparing the developmental capacity of each nudeocytoplasmic hybrid, the more distantly related the species, the earlier does development arrest. The general rule is that nuclear transfers between any amphibian species will form a regulary cleaved late blastula. Two plausible factors relate to limitation of tite developmental capacity of nudeocytaplasmic hybrids. One is an irreversible change in grafted nuclei and another is tunctional incompatibility between the recipient cytoplasm and transplanted nucleus. The later is postulated a more possible cause of the arrestrnent.

Objective: The main goal of this study was to provide a morphological indicator that could be used to select high-quality oocytes of appropriate meiotic and developmental capabilities in pig. The higher quality of immature oocytes, the higher success rates of in vitro maturation (IVM) and in vitro fertilization (IVF). Thus, prior to the IVM culture, it is important to characterize oocytes morphologically and biochemically in order to assess their quality. Two of the largest indicators of oocyte quality are the presence of cumulus cells and status of chromatin. To investigate the effects of porcine oocyte chromatin configurations on the developmental capacity of blastocysts, we assessed oocyte chromatin status according to follicle size and measured the developmental potency of blastocysts. Methods: To sort by follicle size, we divided the oocytes into three groups (less than 1 mm, 1 to 3 mm, and more than 3 mm in diameter). To assess chromatin configuration, the oocytes were assessed for their stages (surrounded nucleolus [SN] germinal vesicle [GV], non-surrounded nucleolus [NSN] GV, GV breakdown, metaphase I [MI], pro-metaphase II [proMII], and metaphase II [MII]) at different maturation times (22, 44, and 66 h). To assess the development rate, oocytes of each follicle size were subjected to parthenogenetic activation for further development. Finally, GV oocytes were grouped by their chromatin configuration (SN, SN/NSN, and NSN) and their global transcriptional levels were measured. Results: SN GV oocytes were more suitable for IVF than NSN GV oocytes. Moreover, oocytes collected from the larger follicles had a greater distribution of SN GV oocytes and a higher developmental capacity during IVM, reaching MII more quickly and developing more often to blastocysts. Conclusion: Porcine oocytes with high-level meiotic and developmental capacity were identified by analyzing the relationship between follicle size and chromatin configuration. The porcine oocytes from large follicles had a significantly higher SN status in which the transcription level was low and could be better in the degree of meiotic progression and developmental capacity.

In the 2000s, financial exclusion of low-income people emerged as a major social problem in South Korea. Microcredit business was first introduced by NGOs to help the poor overcome poverty while the Korean government soon chose to initiate microcredit policies to assist financially marginalized low-income people as a key policy measure to alleviate social inequality and revitalize economy. Unlike the initial expectation that state intervention in microcredit industry would be more effective, the outcome has been much less impressive. This paper aims to examine the poor performance of state-led microcredit in South Korea during the period of Lee Myung-bak administration by employing the concepts of state autonomy and capacity. It finds that the state autonomy, a key characteristic of a developmental state, was high in the sense that the funds had been raised in the face of strong resistance from private financial institutions. Lack of state capacity such as low technocratic expertise and politicization of microcredit policy, however, turned out to be a major stumbling block to the state-led microcredit in South Korea. This study shows that although the Korean government still has strong willingness to intervene in the financial market even in the face of interest groups' opposition, the eventual success of state action largely depends on its capacity to effectively implement financial policies.

The purpose of this study was to verify whether strengthening family competency plays a mediating role in the influence of parents' parenting efficacy on the independent life of children with developmental disabilities. The subjects of the study were 146 parents with developmental disabilities, and data analysis using the SPSS 22.0 program was conducted. The mediating effect was Baron and Kenny Hierarchical regression analysis and sobel-test were conducted. As a result of the study, the positive effect of parents' parenting efficacy on the level of self-reliance and strengthening family competency of children with developmental disabilities was verified. In addition, the positive mediating effect of strengthening family competency was verified between the parenting efficacy of parents and the level of independence of children with developmental disabilities. As a result of the study, it is important to support parents' parenting and family capacity enhancement to support the independence of children with developmental disabilities.

The structure and dynamics of Korean red pine stands established in the riparian zone were studied in the Tsang stream in Mt. Seorak National Park, in east-central Korea. Pine stands were classified into four successional stages, the initial, establishing, competitive, and stabilizing stages, based on the age distribution of a dominant tree, Pinus densiflora, the vegetation stratification, and the microtopography of the riverine environment. The stages usually corresponded to disturbance frequencies, depending on the horizontal and vertical distances from the watercourse. Stands of the initial and establishing stages lacked tree or subtree layers, or both. As stands progressed through the developmental stages, soil particle size became finer and moisture retention capacity was improved. The stand ordination reflected the developmental stage, and the species ordination differentiated species specializing in relatively dry and wet habitats. The results of the analysis of vegetation dynamics provided ecological information which will be useful for understanding the developmental processes of vegetation established in riparian zones. Species diversity indices usually increased across developmental stages, following the typical pattern for successional processes. We discuss the importance and necessity of riparian vegetation in Korea, where most riparian forests have disappeared due to excessive human land use.

Land resources should be managed not only for human utilizations but also for environmental preservation. Based on that, environmental capacity should be estimated in both environmental and developmental ways. This study was performed for developing an estimation model for relative environmental capacity, considering both Development Tolerance Index(DTI), which shows environmental and ecological conservation value and is based on national environmental assessment indicators of the Korea Ministry of Environment, and Development Attractiveness Index(DAI), which shows topographical characteristics and geographical accessibility. The relative environmental capacity in this study can be helpful to coping with the conflict in planning and managing the use of land resources. The relative environmental capacity in this study, however, did not include either environmental or ecological sensitivity of land resources. This limitation should be solved through further research.

Objectives: This paper aims to identify the dimensions of community capacity in a public residence lease apartment complex in Seoul as a case study, and discusses their application to community health promotion. Methods: The research team performed a focus group interview and a brief survey with resident committee representatives to explore community context and to identify the dimensions of community capacity and their order of priority. Results: We identified many groups with different senses of community and various dynamics in the community. Seven dimensions of community capacity were identified. However, there are different developmental stages among them. Also there are some influences with the different directions in a dimension, e.g. leadership and citizen participation. Conclusions: This study illustrated the identification of the dimensions of community capacity focused on the perspective and recognition of the community and community member, as an effort to understand community capacity in domestic community health promotion context.
