본 논문에서는 해양오염 사고 시 방제장비를 얼마나 충분히 확보하여 방제작업 수행을 하여야 하는가가 매우 중요하기에 동적 시뮬레이션을 통한 위험분석을 하여 적정 방제장비의 확보를 위한 합리적 구성과 체계화 방안을 수립하는데 도움이 되고자 한다. 한 국가의 방제능력은 단순히 보유하고 있는 유회수기의 대수나 오일펜스의 길이로만 나타내어지는 것은 아니다. 국가의 방제능력은 방제장비의 양뿐만 아니라 오염 사고시 대응의 신속성과 체계성, 효율성을 고려하여 총괄적으로 표현되는 것이다. 이러한 국가방제능력 산정은 매우 복잡하며, 서로간의 상호관계가 매우 중요시되므로 시스템 다이나믹스 이론을 활용한 파워심을 이용하여 표현하였다.

Irradiation of egg white increased foaming ability significantly. To investigate the protein modification by irradiation responsible for the increase of foaming ability, 3 major egg white proteins were purchased and mixed (7.7 g/L ovalbumin, 1.8 g/L ovotransferrin, 0.5 g/L lysozyme) as a model system and irradiated at 0, 2.5, and 5 kGy. The different protein expressions were evaluated using 2-D electrophoresis and it was found that ovotransferrin was cleaved by irradiation and molecular weight and isoelectric point were changed. In addition, many uncharacterized proteins were found and it indicated that irradiation modified proteins randomly but mainly fragmentation was observed. Therefore, it can be concluded that protein fragmentation of 3 major egg white proteins responsible for foaming ability may be the main reason for the improvement of foaming ability.

Purpose - Previous studies have not paid attention to global self-corporate brand congruity and affective approach from the viewpoint of global self. This study explored an inducement of gratitude that, under the circumstance of corporate association, consumers feel toward corporate's responsible activities, pride related to corporate's ability, and global self congruity. Current researches also have examined positive behavior effects of global self-corporate brand congruity and the feelings on corporate products. Research design, data, and methodology - This research theoretically reviewed that corporate ability and social responsibility association would influence global self-corporate brand congruity, that corporate ability association could induce consumers' sense of pride, and that social responsibility association might induce gratitude. This study, furthermore, examined theoretically whether global self-corporate brand congruity, pride and gratitude could make consumers behave positively toward corporate products, and developed hypotheses. For the empirical analysis with the questionnaires, 231 employees and common people completed the questionnaires, and structural equation model of AMOS 18.0 was used. Results - From the empirical analysis, the outcomes are as followings. First, corporate ability association makes consumers feel proud. Second, corporate social responsible association makes consumers feel grateful. Third, both corporate ability association and social responsibility association let consumers be aware of global self-corporate brand congruity. Fourth, being conscious of each of pride, gratitude and global self-corporate brand congruity prompts consumers to behave positively toward corporate products. Fifth, mediation effects of pride and the congruity in the roles of corporate ability association on the positive behavior, and those of gratitude and the congruity in the roles of corporate social responsible association on the positive behavior are identified. Conclusions - Based on the results, it can be said that a marketing manager should endeavor to make consumers associate the corporate ability and social responsibility. However, the degree of consumers' feelings such as pride and gratitude can differ according to their cultural backgrounds. It is, therefore, needed to be explored by the types of feelings that can be caused more from the difference in cultural backgrounds by corporate association, and to be investigated differently and positively with behavioral effects on the corporate's products between the types.

This study uses the human resource management (HRM) practice and ability, motivation, and opportunities (AMO) theory and corporate social and environmental responsibility, to explore the effects of environmental responsible human resource management practice (ER-HRM) on energy-intensive manufacturing's green technology innovation and organizational effectiveness. A self-completed questionnaire was administered to managers of energy-intensive manufacturing in the Lao PDR. The data was collected from 198 managers of energy-intensive manufacturing for analysis. We used structural equation modeling (SEM) by smart PLS 3.0 to test the hypotheses in this research. The findings have shown a strong direct and positive impact of the environmental ability, motivation, and opportunity of ER-HRM practice on green technology innovation and organizational effectiveness. The ability of ER-HRM practice has the highest influence on green technology innovation and organizational effectiveness. The findings also prove the partial mediation of green technology innovation links ER-HRM with organizational effectiveness. This research is expected to identify the influences of ER-HRM in energy-intensive manufacturing to achieve innovation and performance while reducing emissions.

Purpose: This study aimed to investigate the factors influencing the nursing profession perception of nursing students. Methods: Data were collected with a questionnaire distributed to 305 nursing students in U city. Data were collected from March 30 to June 15, 2019. Data analysis was performed using the SPSS 22.0 program. Results: There were significant differences in the level of interpersonal trust (F=5.42, p<.001), empathy ability (F=3.13, p=.015), interpersonal relationship ability (F=3.64, p=.006) and nursing profession perception (F=11.95, p<.001) on the major satisfaction. The level of interpersonal trust (r=.21, p<.001), empathy ability (r=.27, p<.001) and interpersonal relationship ability (r=.28, p<.001) were positively correlated with nursing profession perception. Also empathy ability (r=.11, p=.047), interpersonal relationship ability (r=.49, p<.001) with interpersonal trust and correlation of empathy ability with interpersonal relationship ability (r=.32, p<.001) were positively correlated with each other. The significant variables that influence the nursing profession perception were grade, major satisfaction, empathy ability and interpersonal relationship ability. These factors were responsible for 21.3%. Conclusion: The results of this study indicate that educational programs are necessary to raise the nursing perception of nursing students and reduce the turnover of nurses.

Reactive oxygen species (ROS) play a significant role in intracellular signaling and regulation, particularly when they are maintained at physiologic levels. However, excess ROS can cause cell damage and induce cell death. We recently reported that eIF2α phosphorylation protects hepatocytes from oxidative stress and liver fibrosis induced by fructose metabolism. Here, we found that hepatocyte-specific eIF2α phosphorylation-deficient mice have significantly reduced expression of the epidermal growth factor receptor (EGFR) and altered EGFR-mediated signaling pathways. EGFR-mediated signaling pathways are important for cell proliferation, differentiation, and survival in many tissues and cell types. Therefore, we studied whether the reduced amount of EGFR is responsible for the eIF2α phosphorylation-deficient hepatocytes' vulnerability to oxidative stress. ROS such as hydrogen peroxide and superoxides induce both EGFR tyrosine phosphorylation and eIF2α phosphorylation. eIF2α phosphorylation-deficient primary hepatocytes, or EGFR knockdown cells, have decreased ROS scavenging ability compared to normal cells. Therefore, these cells are particularly susceptible to oxidative stress. However, overexpression of EGFR in these eIF2α phosphorylation-deficient primary hepatocytes increased ROS scavenging ability and alleviated ROS-mediated cell death. Therefore, we hypothesize that the reduced EGFR level in eIF2α phosphorylation-deficient hepatocytes is one of critical factors responsible for their susceptibility to oxidative stress.

To understand how Bursaphelenchus xylophilus kills pine trees, the differences between the effects of B. xylophilus and B. mucronatus on pine trees are usually compared. In this study, the migration and attacking ability of a non-pathogenic B. mucronatus in Pinus thunbergii were investigated. The distribution of B. mucronatus and the number of dead epithelial cells resulting from inoculation were compared with those of the pathogenic B. xylophilus. Although B. mucronatus is non-pathogenic in pines, its distribution pattern in P. thunbergii was the same as that of B. xylophilus. We therefore concluded that the non-pathogenicity of B. mucronatus could not be attributed to its migration ability. The sparse and sporadic attacking pattern of B. mucronatus was also the same as that of B. xylophilus. However, the number and area of the dead epithelial cells in pine cuttings inoculated with B. mucronatus were smaller than in those cuttings inoculated with B. xylophilus, meaning that the attacking ability of B. mucronatus is weaker than that of B. xylophilus. Therefore, we concluded that the weaker attacking ability of B. mucronatus might be the factor responsible for the non-pathogenicity.

Locals of Control is considered one of the main imporment factors on responsible environmental behaviors(REB). It is defined as an individual's perception of his or ha ability to bring about change through his a her behavior. This psychological construct is divided in two, external and internal. Internal locus of control(ILOC) is imporment as predictor for responsible environmental behaviors. This study was conducted to investigate the Locus of Control and relations with REB in Undergraduate Students. The data were collected mainly through questionnaires and a total of 157 responded questionnaires was analyzed for the study. The statistical methods used in this study were frequency, percentile and correlation. The major findings of this study were (1) Most of undergraduate students had internal locus of control(75.2%). (2) According to region, rural students showed high levels in ILOC and REB.

A thermotolerant bacterium, designated as PHS1, was isolated from a hot spring in Pohang, Korea, on the basis of its ability to grow on BTEX as a sole carbon source. We cloned and sequenced the entire BTEX-degrading pathway genes of PHS1 and found that two multicomponent mono-oxygenases together with meta-pathway genes are responsible for the BTEX biodegradation.
