In this study, the effectiveness of integrated group program for battered women in the shelters carried out and the program's effectiveness concentrating on the depression is evaluated. The integrated group program was developed based on the National Family Violence Survey and other studies about battered women's characteristics. The major outcomes of the study are following. First, depression score of the test group(N=10) in comparison with the comparison group(N=18) decrease with statistical significance. Second, among the sub-symptoms of depression, the symptoms of affective, cognitive, and behavioral depression significantly decrease. These findings show that an integrated program is needed to improve battered women's mental health; it includes not only a mental health intervention but many other services such as family violence education, communication training, social support networking, economic independence improvement and child rearing.

This paper examines the characteristics and determinants of welfare attitudes in Korea. Based on Survey data, this study focuses mainly on how social-economic position variables, welfare status and welfare compliances influence attitudes towards welfare. Welfare attitudes can be classified by five areas as follows: legitimacy of welfare functions, affordability of welfare costs, need-based welfare principles, responsibility of welfare provision and adequacy of welfare spending. There are the major findings. First, attitudes towards welfare is identified state-friendly or pro-welfare attitudes. Second, among the social-economic position variables, welfare status and welfare norms variables, welfare compliance has statistically the most significant effects on welfare attitudes. Third, the level of pro-welfare attitudes is largely determined by welfare norms and images espoused by individuals. These findings suggest that we can not apply cleavages thesis which are developed by studies on the support for welfare state.

This article focuses on the use of case management in the Self-support program. Case management is a service modality which provides integrated services for people with multiple needs in the community. The goal to accomplish self-sufficiency of working participants in Self-Support Programs is positively affected by the efforts to reduce high social risks they are exposed. It is recommended that the agencies running Self-support programs apply case management to increase the quality of lives as well as the effectiveness of exiting statuses of conditional welfare recipients. Several service considerations of case management are recommended for the change in the structure and functioning of the Self-Support Program: Integrated view and contextualized thinking, empowerment-oriented approach, and a development of the community support system through networking. Types of case management and practice roles of the case manager applicable to the Self-Support Program are also recommended. Structural aspects of an organization, inter-organizational linkages and contextual factors need to be considered to improve problematic conditions that have not enough resources and appropriate authorities in providing case management functions.

The elderly suicide has become a social problem, and the need for academic and practice-based knowledge for preventing elderly suicide has been addressed. Unlike previous literature focusing on identifying risk factors, this study aimed to address protective ones which help to overcome suicidal behavior among older adults. The purpose of this qualitative study was to understand how older adults get over being suicidal and get back to life, and to identify what helps them during the process. Both in-depth interviews with 35 elderly with suicide attempts and field notes were analyzed through thematic analysis. The older adults described a pathway to rediscovering a 'will to live' that was related to a 'mind's incline' and included two kinds of protective factors. Based on the findings, it addresses the implication for the elderly suicide prevention utilizing protective factors.

There has been no studies that compare services of residential care centers, group homes, and foster homes although out-of-home care services differ from each other depending on the types of out-of-home care. This study compared care satisfaction of 481 children in residential care centers, group homes, and foster homes for five years. Futhermore, factors that predict care satisfaction of the children were identified using multi-level modeling analyses. As results, this study found that care satisfaction of children in group homes was the higher than that in foster homes and residential care centers. In addition, self-esteem, social support, and types of out-of-home services were identified as significant predictors of changes in care satisfaction. Based on the study results, suggestions to help children adapt to out-of-home care and improve out-of-home care satisfaction were made.

Bioinformatics is a discipline to support biological experiment projects by storing, managing data arising from genome research. In can also lead the experimental design for genome function prediction and regulation. Among various approaches of the genome research, the proteomics have been drawing increasing attention since it deals with the final product of genomes, i.e., proteins, directly. This paper proposes a data mining technique to predict the structural characteristics of a given protein group, one of dominant factors of the functions of them. After explains associations among amino acid subsequences in the primary structures of proteins, which can provide important clues for determining secondary or tertiary structures of them, it defines a sequence association rule to represent the inter-subsequences. It also provides support and confidence measures, newly designed to evaluate the usefulness of sequence association rules, After is proposes a method to discover useful sequence association rules from a given protein group, it evaluates the performance of the proposed method with protein sequence data from the SWISS-PROT protein database.

In this work, a nano-sized samaria-doped ceria(SDC) was prepared by a urea-based hydrothermal method and characterized by XRD, FESEM and TEM. It was observed that the increase in synthesis time and temperature gave rise to crystallity and particles size. Moreover, the synthesised powders had a excellent ion-conductivity(0.1 S/cm at 600~$800^{\circ}C$) which is suitable for electrolyte of intermediate temperature-solid oxide fuel cell(IT-SOFC). Subsequently for use as electrolyte for anode-supported IT-SOFC, we tried to deposit the SDC powder on a porous NiO-SDC substrate by electrophoretic deposition(EPD) method. From the FESEM observation, a compact

During start up and shut down of a proton exchange membrane fuel cells (PEMFC), the performance and lifetime of PEMFC were reduced. In this study, effect of startup and shutdown were investigated in dead-end type PEMFC using oxygen as a cathode gas with polarization curve, impedance spectroscopy (EIS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Dummy load which eliminates residual hydrogen and oxygen during startup and shutdown operation should be applied to mitigated the degradation of PEMFC performance. At 50% relative humidity (RH) under the repetitive on/off cycling, the cell performance decayed faster than at 100% RH because of corrosion of the cathode carbon support. Water suppling into cell reduced the degradation rate of dead-end type PEMFC during start up and shut down cycling at 50% RH.

Metal foams have a cellular structure consisting of a solid metal containing a large volume fraction of pores. In particular, open pores which are penetrable pores are necessary for industrial applications such as in high temperature filters and as support for catalysts. In this study, Fe foam with greater than 90% porosity and 2-mm pore size was successfully fabricated using a slurry coating process and the pore properties were characterized. The Fe and $Fe_2O_3$ powder mixing ratios were controlled to produce Fe foam samples with different pore sizes and porosity. First, the slurry was prepared through the uniform mixing of powders, distilled water, and polyvinyl alcohol(PVA). The amount of slurry coated with the PU foam increased with increasing $Fe_2O_3$ mixing powder ratio, but the shrinkage and porosity of the Fe foams decreased, respectively, with increasing $Fe_2O_3$ mixing powder ratio.

Computational simulation has been performed to design optimally the filtration system for IGCC pilot plant. It was analyzed how the different inflow pattern influences the flow field and the particle behavior in a filter vessel. The particle loading onto the filter surface lowers significantly and decreases dramatically with particle size when the dusty gas flows into the filter vessel with a shroud tube through a tangential inlet setup tangentially on the vessel outer wall. However, the particle loading is considerably high when the dusty gas enters the filter vessel through a normal inlet setup vertically on the vessel top wall, and the decrease of the particle loading with particle size is not steeper compared with the tangential inflow pattern.
