Purpose: The purpose of this study was to develop a mentoring program for stress management among Korean adolescents and to assess the effects of the program. Methods: The nonequivalent control group (CG) pretest-posttest design was used in this study. The mentoring intervention was delivered to 18 middle school students (males and females) but nothing was done to the control group consisting of 18 students. The mentoring intervention was conducted by seven nursing students who participated in the program as mentors using various methods such as individual meetings and group activities. The dependent variable was stress level. Results: The program consisted of group and individual mentoring. At follow-up, although the mentees's satisfaction was high and they stated qualitatively positive experience, the difference of stress level between the two groups was not significant. Conclusion: If future mentoring programs reflect the limitation of the current program, they may have potential as developmentally appropriate interventions for stress management of adolescents, and enable nursing students to gain confidence in their professional capability.

Comprehensive development projects were carried out on the Han River from 1982 to 1986 for the purpose of creating a more serviceable places such as a riverside parks and autoroads and so on. However because of the river development, river ecosystem and function were destroyed. And many local autonomous entity follows comprehensive development projects as if it is a model case. To investigate the impact that the river development effects the river ecosystem, two sites which are Anyangcheon and Sooipcheon were surveyed in the right of around plants ecosystem and structure. Two sites are creek of the Hna River. Sooipcheon maintains the sound ecosystem. It has sufficient carrying capacity for the river recreation activity. The reason is that a hydrophyte absorbs nutrients from the stream and the river ecosystem meets the around terrestrial one neturally. Number of hydrophyte increase from upstream going forward to downstream. Number of hydrophyte increase from upstream going forward to downstream. Anyangchoen is seriously polluted stream out of many branch stream of the Han river. In the upstream various woody plants and hydrophyte appeared. But from the river developed area at midstream, naturalized plants dominated such as Bidens tripartita, panicum dichotomiflorum etc. To manage the creek ecologically, hydrophyts were introduced in partly for natural purification after rehavilitate the riverside, and steadily monitoring is demanded.

The objective of this planning proposal is to rehabilitate the urban stream which has been ecologically disturbed in the urban process. The experimental stream, Su-am stream located in Anyang City is typical urban stream in adjacent land use and the spatial condition. The stream in the watershed context, is the second tributary of Han River, in the Anyangcheon watershed. The Characteristics of the stream reach were analyzed by the river corridor survey. In the conceptual phase, Rehabilitation Programs were established based on the hydrological, ecological and spatial characteristics of the stream. Spatial zoning concept according to the characteristics of the stream and adjacent land use, was suggested 4 types of zoning; ecological preservation zone, natural landscape zone, neighborhood water-friendly zone and CBD water-friendly zone. Implementation Practices can be summarized as follow: For The longitudinal river continuum, some In-stream practices were suggested and implemented; such as channel alignment, step & pool, pool & riffle and low-flow channel bank. For latitudinal continuum and intimate spatial relationship between Sam-duk Park & Su-am stream, gentle sloped bank was planned and implemented. After stream improvement & ecological Implementation, follow-up monitoring and adaptive management programs will be a meaningful process for ecological rehabilitation.

The most important and largest commercial outlet of fly ash in Korea is a replacement material of Portland cement in concrete industry. The high level of unburned carbon in ash brings about some malfunctions in concrete. Therefore, fly ash is refined to improve the quality as a concrete additive. In this process, a lot of the residual carbon is produced, and discarded now. In the present study, to find out a valuable outlet of the enriched carbon samples, the basic morphology of residual carbon in fly ash from Boryung power plant was investigated. The unburned carbon characterization included shape, size measurement, and chemical analysis was examined using scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDX).

River restoration plan and selection method are needed to reflect the diversity of river. Meanwhile, the ultimate purpose of river restoration is natural recovery of the river. Recently. hydrophilic enhancement is a tendency to include. In this study, naturalness of a river was used to establish alternative for the natural river recovery. Also, naturalness of a river calculated by using the evaluation of river naturalness that was developed using multi-criteria decision making to fit the environmental conditions in Korea. After selection the evaluation items for assessing the naturalness of the river based on the characteristics of the river, multiple alternatives were constructed and the naturalness of river for each of those alternatives were estimated. Comparing the estimated values has made the measurement of the natural recovery effect for each alternative efficient.

최근 정부의 공기업 경영혁신계획에 따라서 민영화와 경영혁신 대상 공기업이 확장되었다. 이에 따라서, 한국지역 난방공사(이하 '한난')는 1차 민영화 대상 공기업으로서 단계적 민영화를 위하여 안양 및 부천 사업소를 한국전력공사(이하 '한전')의 열병합발전소와 통합매각하여 2001년 51%이상 지분을 매각함으로써 민영화를 완료하도록 추진방안이 수립된 상태이다. 이렇듯 가시화된 정부의 에너지산업에 대한 경쟁 촉진 및 규제완화는 정부주도의 하향식 계획을 지양하고 에너지 구성(energy mix)을 시장에서 결정되게 하자는 것이다. 이는 관련업체간에 해당에너지의 사업주체에 대한 경쟁이 아니라 개별기업이 다양한 에너지사업을 운영하면서 한 기업의 최적 에너지 구성을 시장원리에 따라서 자체적으로 결정한다는 것이 핵심사항이다. 따라서, 현재 한난과 에너지관리공단이 운영 및 소유주체로 되어 있는 국내 집단에너지사업은 정부방안에 능동적으로 대처하고, 특히 에너지산업 변화에서 제기능을 담당할 수 있도록 합리적이고 효율적인 발전계획 및 민영화 방안을 수립할 필요가 있다. 본고에서는 현재 추진중인 국내 에너지 산업 구조개편에 따른 집단에너지사업의 발전방향을 정책적인 측면에서 제시하고자 한다. 논의의 대상은 국내 집단에너지 사업으로, 공업단지 집단에너지사업을 제외한 지역냉난방 사업을 중심으로 하여 전력 및 가스사업고의 연계방안 등이 주요 사항이다.

This study was designed to investigate the intracellular signaling pathways and immunoenhancing effect of macrophage activation by crude polysaccharides (CPP) extracted from citrus peels. CPP did not affect the cytotoxicity of RAW264.7 cells, but showed dose-dependent effects on cell viability. Also, CPP showed high production of chemokine (nitric oxide (NO)) and cytokines (interleukin (IL)-6 and tumor necrosis factor (TNF)-α). CPP increased IL-6, TNF-α, and inducible nitric oxide synthase (iNOS) mRNA expression dose-dependently. CPP also strongly induced the phosphorylation of the ERK, p38, and IκBα pathways in RAW 264.7 cells. In anti-pattern recognition receptors (PRRs) experiments, the effect of CPP on NO production was strongly suppressed by neutralizing toll-like receptor (TLR)2, TLR4, and Dectin1 antibodies, whereas IL-6 and TNF-α production by CPP was mainly suppressed by mannose receptor (MR). Therefore, these results suggest that CPP treatment-induced NO production was regulated by the ERK, p38, and NF-κB pathways through TLR2, TLR4, and Dectin1 receptors, whereas IL-6 and TNF-α production was primarily regulated by the ERK, p38, and NF-κB pathways through MR receptors.

In this paper, an efficient implementation of AES encryption algorithm is presented for CCTV image security using C# language. In this approach, an efficient S-Box is first designed for reducing the computation time which is required in each round process of AES algorithm, and then an CCTV image security system is implemented on the basis of this algorithm on a composite field GF(((22)2)2). In addition, the shared S-Box structure is designed for realizing the minimized memory space, which is used in each round transformation and key scheduling processes. Through performance evaluation, it was confirmed that the proposed method is more efficient than the existing method. The proposed CCTV system in C# language using Visual studio 2010.
