Objectives: There is higher rates of experience of suicide ideation and suicide attempt of adolescents in the Lima and Callao region compared with the results of the epidemiological study (2013) conducted by Peru National Institute of Mental Health and the Global School-based Student Health Survey (2010) which is was conducted among adolescents across all regions of Peru. Based on the PRECEDE model, this study analyzed the prevalence and the factor associated with the suicide attempt among the adolescent in a poor urban area in Peru. Methods: A stratified random sampling was used for the survey to select study participants from the 6 secondary schools based in Comas or Callao. The survey was conducted November 25th and December 4th in 2015 and a total of 738 individuals included in the analysis. In order to analyze factors influencing suicide attempt, comparison of predisposing factor, reinforcing factor, enabling factor, behavioral factor, environmental factor, psychological factors by suicide attempt and suicide risk group were identified through the chi-square test and hierarchical logistic regression. Results: Results showed that those who reported having less parental understanding, less time spent with parents, and 'almost none/none' for parental affection had more experience of suicide attempt and were more likely to sort into the high suicide risk group. Also, a greater proportion of those with the experience of suicide attempt had more experience of smoking and alcohol consumption, and experience of physical abuse and feeling insulted and depression in comparison to that of those without experience of suicide attempt. Variables that had a significant effect on suicide attempt included depression, subjective happiness, smoking experience, sexual intercourse, involvement in fight, parental affection, and gender (male). Conclusions: The results of the current study can serve as grounds for the necessity of acknowledging that adolescent suicide does not simply depend on a couple of factors, but arises from situations in which individual, home, school, social factors influence one another, and therefore adolescent suicide should be prevented and addressed through a multi-dimensional and integrated approach.

The purpose of this study is to understand the mediating effect of grit in the relationship between academic achievement satisfaction and Academic Engagement of middle school students. To this end, a survey was conducted on 575 middle school students in Changwon, Gyeongsangnam-do, on academic achievement satisfaction, Academic Engagement, and grit. This research was carried out by hierarchical regression analysis was conducted to understand the correlation analysis and mediating effect between major variables, and The significance of the mediating effect was verified by the Sobel test. As a result of the study, First, correlation analysis revealed a positive correlation between academic achievement satisfaction, grit, and Academic Engagement. Second, regression analysis showed that both consistency of interest and perseverance of effort were partially mediated between academic achievement satisfaction and Academic Engagement. This means that academic achievement satisfaction not only directly affects middle school students' Academic Engagement, but also has an indirect effect through grit. Finally, In order to increase the academic enthusiasm of middle school students, learning counseling plans such as education and counseling plans to improve academic interest and develop various learning motivation improvement programs were discussed.

The purpose of this study is to understand the mediating effect of self-leadership in the process of understanding the effects of nursing job performance and job satisfaction in the nursing work environment perceived by nurses. In this study, nurses who worked for more than one year at three general hospitals located in Province A. Total of 225 data were used for the final analysis. Date analyzed using the SPSS 22.0 program by t-test, ANOVA, Pearson's correlation coefficient and hierarchical regression analysis. Self-leadership was found to play a partial mediating role in the relationship between nursing work environment and nursing job performance(z=4.30, p<.001) and between nursing work environment and job satisfaction(z=3.70, p<.001). Therefore, in order to improve nursing job performance and job satisfaction, it will be necessary to establish a management plan that can improve the nursing work environment and improve self-leadership.

In this paper, we propose an adaptive concurrency control scheme to reduce conflicts and working time in the cooperative work in mixed reality. To this ends, we first classified the goals, tasks and ownerships of the cooperative work. Then, the classified relationships are mapped according to their temporal and hierarchical relationships of shared object manipulation in the cooperative work. The proposed system provides adaptive concurrency controls of the shared object according to temporal orders of the sub-goals. With the proposed scheme, a participant is enable to move and rotate a shared object although another already has an ownership of the shared object in a specific order of the sub-goal. Thus, the proposed system provides adaptive and realistic cooperative working environment. We conducted a user study of the proposed scheme. The proposed system could reduce conflicts and working times comparing to conventional approaches.

The aim of this essay was to investigate Marlow's desire for constructing enlightenment subject of knowledge and power sustained by the collusion of imperialism and patriarchy in Joseph Conrad's Heart of Darkness. Marlow's narrative, based on his journey up the river in Africa to retrieve Kurtz, attempts to conceptualize himself as the subject of the enlightenment reason and rationality. In the novella, collusive network of ideologies of empire and gender contributes to the making of a Western Enlightenment subject. Marlow eulogizes himself for realizing the harsh realities of imperialism, political domination and economic exploitation of the natives in Africa. However, Marlow is a colonial subject who has been ruled by the hierarchical system of thought in the Western logocentrism. He is not aware that his narrative has already been infiltrated by the ideological discourse of the totalitarian enlightenment. His narrative in effect is not a self-congratulatory testimony to truth and realities but a narcissistic and self-defeating document. Marlow unconsciously employs the totalitarian ideologies of empire and gender in order to relegate the African natives to the inhuman existence and to consign women to the sphere of illusion.

This paper presents a hybrid numerical approach, which combines a two-phase Navier-Stokes model (NS) and the fully nonlinear potential theory (FNPT), for modelling wave-structure interaction. The former governs the computational domain near the structure, where the viscous and turbulent effects are significant, and is solved by OpenFOAM/InterDyMFoam which utilising the finite volume method (FVM) with a Volume of Fluid (VOF) for the phase identification. The latter covers the rest of the domain, where the fluid may be considered as incompressible, inviscid and irrotational, and solved by using the Quasi Arbitrary Lagrangian-Eulerian finite element method (QALE-FEM). These two models are weakly coupled using a zonal (spatially hierarchical) approach. Considering the inconsistence of the solutions at the boundaries between two different sub-domains governed by two fundamentally different models, a relaxation (transitional) zone is introduced, where the velocity, pressure and surface elevations are taken as the weighted summation of the solutions by two models. In order to tackle the challenges associated and maximise the computational efficiency, further developments of the QALE-FEM have been made. These include the derivation of an arbitrary Lagrangian-Eulerian FNPT and application of a robust gradient calculation scheme for estimating the velocity. The present hybrid model is applied to the numerical simulation of a fixed horizontal cylinder subjected to a unidirectional wave with or without following current. The convergence property, the optimisation of the relaxation zone, the accuracy and the computational efficiency are discussed. Although the idea of the weakly coupling using the zonal approach is not new, the present hybrid model is the first one to couple the QALE-FEM with OpenFOAM solver and/or to be applied to numerical simulate the wave-structure interaction with presence of current.

This study aimed to investigate the effect of firefighters' social capital on subjective happiness. This research was conducted from Jun 12 to Aug 25, 2017, and a descriptive analysis, t-test, hierarchical regression analysis was carried out based on the results of a survey with 351 firefighters in Gyeonggi-do to verify the research hypothesis. As a result, it was revealed that network(${\beta}=.315$, p<.001), trust(${\beta}=.293$, p<.01), cooperation(${\beta}=.225$, p<.01) and trust among other sub-variables of firefighters' social capital had significant effects on subjective happiness. Based on the results, this research suggested that various measures to strengthen social capital would be required in order to improve fire-fighters' happiness: efforts to increase trust within the organization, political support for vitalizing formal network as a communication channel among firefighters organizations, encouraging interest in the community and promoting informal network such as volunteer work, developing transparency in operating the organizational policy and system, etc.

The purpose of this study is to provide academic and practical implications through empirical analysis on the moderating role of SHRM that is relatively lacking in the relationship between CLMRC and performance. In order to achieve the research purpose, data were collected from 123 CEOs of Korean companies. The reliability and validity of the collected data were examined and the hypothesis was verified by hierarchical regression analysis. The results of this study show that CLMRC has a meaningful positive(+) effect on both net profit and sales per person, and SHRM has shown to have a moderating effects between CLMRC and sales per person, CLMRC and net profit. Through this analyzes, CLMRC can enhance the management performance, and in this process, the more strategic the human resource management(HRM) is, the more the impact on the management performance is strengthened. Implications for CLMRC and SHRM, limitations of the study and suggestions for future researches are discussed.
