The aim of this study was to test the correlation of ethical values and perception of biomedical ethics in nursing students. Data was collected from September 10th to October 5th 2012, was analyzed using the t-test, the one-way ANOVA, the Scheffe, the Multiple regression and Pearson's correlation. The average point of consciousness of biomedical ethics was 2.98(${\pm}0.2$). The highest score of 3.27(${\pm}0.5$) was seen in the category of the ethics for 'right to life of the fetus', the lowest score of 2.70(${\pm}0.4$) was seen in the 'organ transplantation'. As a result of analyzing on general and specific aspects, the difference was found in gender and ethical values(F=6.148, p=<.001). In gender, the score of biomedical ethics(r=0.108, p=.003) and ethical values(r=-0.185, p=.002) were showing a positive correlation. The predictors of biomedical ethics was gender(${\beta}$=0.205, t=3.399, p=<.001), the possibility of biomedical ethics problems depend on the development of science (${\beta}$=0.142, t=2.261, p=0.025) and ethical values(${\beta}$=0.189, t=3.119, p=0.002). These results can provide a basic data to enhance the consciousness of biomedical ethics and establish a educational program of biomedical ethics for nursing students.

This paper investigated catalytic and adsorption equations among the technologies for removing hazardous substances generated in the semiconductor process. As the semiconductor industry develops, harmful substances used and discharged in the semiconductor process are also increasing. Hazardous substances adversely affect the global environment in terms of atmospheric and water quality. As regulations on the emission of harmful substances are strengthened in the 21st century, it is expected that there will be limitations in industrial development in the future. Therefore, technology for removing harmful substances generated in semiconductor processes is essential. In this paper, the goal is to remove PFCs, which are harmful substances, through adsorption technology and catalyst technology. Descriptions from the semiconductor process to the technology in which harmful substances generated are removed were summarized.

Lithium-ion batteries have greatly expanded along with the mobile phone market, and as the electric vehicle business is activated in earnest, they will attract many people's attention even afterwards. Until now, many people have attracted attention to the recovery of valuable metals inside lithium-ion batteries, but graphite, which is mainly used as an anode material, is also worth recycling. Therefore, in order to recover graphite with high purity and valuable metals, graphite that can be used as an anode material of a secondary battery may be generated again through a regeneration process of purifying and separating graphite from a waste lithium-ion battery and recovering electrical characteristics of graphite. This paper describes the process of converting waste graphite into regenerated graphite and the environmental and economic effects of regenerated graphite.

조기후두암은 치료 목표는 생명을 구하면서 동시에 후두기능을 최대한으로 보존하는 것이라고 할 수 있는데, 치료자의 철학과 환자의 선호도에 따라 방사선 치료, 레이저 수술 그리고 후두부분적출술 등의 방법이 적용되고 있다. 어떤 치료 방법이던 재발암에 대한 구제치료를 포함하면, 궁극적인 생존율은 거의 비슷하다. 그러므로 일차 치료후 얼마나 적극적으로 환자를 추적관찰하고, 적절한 구제수술을 시행하느냐에 따라 생명의 보존 그리고 재발암에서의 기능의 보존 여부가 좌우된다고 할 수 있다. 향후 보다 체계적인 추적 관찰법과 최소의 환자 부담으로 최대의 성과를 거둘 수 있는 치료방법 이 연구되어져야겠다.

Hibiscus cannabinus L. is a plant in the Malvaceae family, that was seeded at June 1st in 2010 and harvested at November 18th. The present study was designated to investigate the safety for host cells, antibacterial effects of Hibiscus cannabinus L. of flower (HCME-F) or leaf (HMEF-L) methanol extract for typical Gram's positive bacteria (St. aureus and Str. epidermidis) or Gram's negative bacteria (S. typhimurium and E. coli). In treatment of different concentrations of HCME-F or HMEF-L (1, 50 and $100{\mu}g/ml$), cytotoxic effects were not shown to RAW 264.7 cells until 24 h incubation. In determination of antibacterial activity of HCME-F or HMEF-L, the antibacterial activities for St. aureus and Str. epidermidis were markedly increased compared to that of untreated control group, but antibacterial activity of HCME-F or HMEF-L for S. typhimurium and E. coli were not changed. Taken together, we demonstrated that methanol extract of HCME-F or HMEF-L showed the safety for RAW 264.7 cells and antibacterial activities for Gram's positive pathogenic bacteria St. aureus and Str. epidermidis. These findings suggest that a methanol extract of Kenaf flower or leaf may be useful alternatives of conventional chemotherapies for dermatitis and mastitis causing Gram's positive pathogens such as Stapylococcus spp. and Streptococcus spp. in domestic animals and humans.

This study was conducted to estimate genetic parameters for growth traits using multivariate animal models in Yorkshire breed. For the study, 16,202 records for growth traits collected between the year 1999 and 2005 from Yorkshire pigs in K GGP were used. The effects of environmental factors such as sex, birth year, birth season, parity and birth weight group affected growth traits significantly (p<0.01). Birth weight tended to be positively correlated with average daily gain (ADG) and lean percent. But it seemed to affect age at 90 kg, average adjusted backfat thickness (BF), and eye muscle ares (EMA) negatively. For average pig suckling weight (ASW) and total weight at suckling (TWS), the higher birth weight is the better performance. But, in case of total number of born and number of suckling, the result was shown vice versa. Approximately 10~30% lower heritability estimates were obtained for growth traits by using the model that includes descriptions of common litter effects (CL) than by using the model that ignores those (NCL) for more accurate estimation of heritability. The estimates of heritabilities were 0.468, and 0.328 for ADG, 0.474 and 0.326 for age at 90 kg, 0.452, and 0.396 for BF, 0.240 and 0.200 for EMA and, 0.458, and 0.380 for lean percent in NCL and CL, respectively. Therefore, in order to estimate optimal genetic parameters, it could be inferred that the statistical model which considers litter effects must be applied.

Recently, stream longitudinal connectivity has been a topic of investigation due to the frequent disconnections and the impact of aquatic ecosystems caused by the construction of small and medium-sized weirs and various artificial structures (fishways) directly influencing the stream ecosystem health. In this study, the international and domestic research trends of the longitudinal connectivity in aquatic ecosystems were evaluated and the applicability of fish-based longitudinal connectivity models used in developed countries was analyzed. For these purposes, we analyzed the current status of research on longitudinal connectivity and structural problems, fish monitoring methodology, monitoring approaches, longitudinal disconnectivity of fish movement, and biodiversity. In addition, we analyzed the current status and some technical limitations of physical habitat suitability evaluation, ecology-based water flow, eco-hydrological modeling for fish habitat connectivity, and the s/w program development for agent-based model. Numerous references, data, and various reports were examined to identify worldwide longitudinal stream connectivity evaluation models in European and non-European countries. The international approaches to longitudinal connectivity evaluations were categorized into five phases including 1) an approach integrating fish community and artificial structure surveys (two types input variables), 2) field monitoring approaches, 3) a stream geomorphological approach, 4) an artificial structure-based DB analytical approach, and 5) other approaches. the overall evaluation of survey methodologies and applicability for longitudinal stream connectivity suggested that the ICE model (Information sur la Continuite Ecologique) and the ICF model (Index de Connectivitat Fluvial), widely used in European countries, were appropriate for the application of longitudinal connectivity evaluations in Korean streams.
