A self-sufficiency service has worked as a typical workfare policy combined with public assistance in Korea since 2000. Despite of its long history, three core pillars in administrating the self-sufficiency service, policy, research, and practice, have respectively understood the meaning of self-sufficiency in terms of their own interests. As a result, the self-sufficiency service has recently faced with its own identity issues by showing failures to its environmental changes. The current situation makes it necessary to reconceptualize the definition of self-sufficiency by exploring its in-depth understanding perceived by service providers. Specifically, we analyzed practical reflections on 35 service providers' experiences which were collected via focus group interviews for two hours. The study findings presented that service providers had two antithetical approaches towards self-sufficiency. While a dominant approach to self-sufficiency has been concentrated on improving clients' economic outcomes such as employment, job retention, the escape from welfare trap, and increasing earnings and assets, the other approach has been extended to empower clients and achieve their well-being and quality of life. Yet, these contrary perspectives have led to suffer from their role confusions and identity crisis between the work-ready process and the employment-oriented outcomes. Specifically, they described self-sufficiency in terms of psychological, social, and integrated aspects. The psychological aspect included a process of developing inner strengths, intensifying job motivation, and coping with barriers of employment. The social aspect meant a path toward social integration through recovering human relationships. The integrated aspect covered more comprehensive support for their recovery of daily life and autonomy to make a decision for their own life. In conclusion, the study findings suggest that self-sufficiency should be more extensively considered as a stepwise process towards work-ready preparations beyond ultimate economic outcomes. Such an extended concept of self-sufficiency could contribute to restructuring the whole practice of self-sufficiency including organizational and program changes in the fields.

A mesh node, a component of a mesh network, is connected with the network by dynamic routing using routing protocol and collects the information of adjacent or connected mesh nodes for its self-management and settings. Also, it relays packets between the mesh nodes and provides AP(Access Point) with its corresponding functions based on IEEE 802.11 a/b/g for clients' access to the network. In this paper, the study focused on the design and performance tests of Wireless Mesh Network(WMN) which is applied to the wireless communication network for the CBTC(Communications Based Train Control) system. The WMN was established on a K-AGT test-line (Kyeongsan city, Gyeongsangbuk-do), and to verify the applicability, its operation and performances are checked by measuring the data throughput, delay latency, quality measurements such as transmission loss, radio interference and path recovery and setup between the on-board and wayside.

This thesis presents Bipolar transistor with SAVEN(Self-Aligned VErtical Nitride) structure as a high-speed device which is essential for high-speed system such as optical storage system or mobile communication system, and proposes 0.8${\mu}m$ BiCMOS Process which integrates LDD nMOS, LDD pMOS and SAVEN bipolar transistor into one-chip. The SPICE parameters of LDD nMOS, LDD pMOS and SAVEN Bipolar transistor are extracted, and comparator operating at 500MHz sampling frequency is designed with them. The small Parasitic capacitances of SAVEN bipolar transistor have a direct effect on decreasing recovery time and regeneration time, which is helpful to improve the speed of the comparator. Therefore the SAVEN bipolar transistor with high cutoff frequency is expected to be used in high-speed system.

Compared with traditional patch-based sparse representation, recent studies have concluded that group-based sparse representation (GSR) can simultaneously enforce the intrinsic local sparsity and nonlocal self-similarity of images within a unified framework. This article investigates an accelerated split Bregman method (SBM) that is based on GSR which exploits image compressive sensing (CS). The computational efficiency of accelerated SBM for the measurement matrix of a partial Fourier matrix can be further improved by the introduction of a fast Fourier transform (FFT) to derive the enhanced algorithm. In addition, we provide convergence analysis for the proposed method. Experimental results demonstrate that accelerated SBM is potentially faster than some existing image CS reconstruction methods.

The purpose of this study was to examine the factors related to adolescence' post-sexual assault attitudes and behaviors. 906 students from 5girls high schools completed self-reported questionnaires. Independent variables are sexual attitudes, rape myth acceptance, perceived importance of sexuality education, parent sexuality education, parent closeness, parent superintendence, family functioning and socioeconomic variables. The data were analyzed by Factor Analysis, Correlation Analysis, Stepwise Multiple Regression Analysis using SPSS program. The significant influencing factors were home sexuality education, perceived necessity & importance of sexuality education, parent closeness, parent superintendence, family functioning, grade, vocational school, rape myth(rapists are mentally ill, dating partner would not be rapist. rapists are stranger), sexual attitudes(sexual permissiveness, gender equality, family planning, STDs & prostitution, marriage and divorce and abortion), and dating experience. Examination of barriers to post-sexual assault coping behaviors and attitudes is critical component of victim recovery and rape prevention. This study would gives basic information to the effective prevention and coping program development related to sexual assault.

Purpose - The purpose of this study is to understand how retailers' green practices influence customer environmental values and their organic food purchasing intention. Research design, data, and methodology - Data were collected from randomly intercepting retail shoppers (n=719) departing from 33 retail stores selling organic food products located in Florida, USA. U.S. Data were analyzed using descriptive statistics, CFA and Hierarchical regression analyses. Results - Results documented that customer environmental values (social-altruistic values and biospheric values) were determinants of organic food purchasing intention. Retailers' green practices representing'green self-governance'were found to significantly enhance the effects of customer environmental values upon organic food purchasing intention. Conclusions - This study successfully demonstrated that customers'willingness to purchase eco-friendly products can be greatly increased when having a positive perceptions toward retailers'green practices such as environmental friendly waste management, environmental improvement of packaging, taking back packaging and recovery of the company's end-of-life products.
