This study analysis the effects of the relationship between LMX and affiliation-OCB, challenge-OCB which is voluntary behavior of organizational members. For this study, the effect of LMX on AOCB and COCB, as well as the mediating effect of AOCB behavior, the moderating role of toxic leadership, were analyzed. The results of studies are as follows. First, LMX had a positive effect on AOCB and COCB, respectively. Second, AOCB has a mediating-effect between LMX and COCB. and Third, toxic leadership confirmed the moderating-effect between LMX and AOCB, and finally the moderated-mediating-effect through AOCB in the relationship between LMX and COCB. Therefore, it was analyzed that the quality of the relationship between leader and member in the organization is an important factor in expanding the positive and voluntary behavior of members in the organization. In addition, since toxic leadership weakens positive and voluntary civic behavior for organizational members, it suggests the need for strategy to overcome toxic leadership for an efficient organization management.

A military is not an organization that seeks profits, such as a company, or a research institute whose results and outcomes can produce. Therefore, it can be said that the nature of the bureaucracy is stronger than any other organizations, which perform the task centered based on ranks. In addition, as military missions deal with national and operation security which is closed with each other and more conservative compare to other organization. In this circumstance, the role of military organization and leaders is to carry out their duties with the cost of people's lives, and indeed, leades and leadership in military are more important than those of any organizations. However, many researches are lacking or focused on leadership research in a limited field, especially positive field, developmental, constructive leadership research and researches that are not focused on that area are limited. Already in the United States, research on negative leadership has been actively conducted under the direction of the Secretary of US Army Thomas E. White in 2003, how toxic leadership is serving in military organizations and on the battlefield. Now they realize how toxic leadership had impact on missions in military organizations and on the battlefield. The purpose of this study is to collect and analyze qualitative and quantitative data on the negative leadership of military organizations that have not been studied. The aim of this study was to establish a literature study on the scope and behavior of toxic leadership among negative leadership and to build empirical data on toxic leaders of current military organizations, and to create occupations that occur when subordinates work with toxic leaders. This study analyzes changes in satisfaction and organizational cohesion that mediates results and causes. This study will be more urgent and important for groups that prioritize groups and organizations over individuals, and it may provide new directions for the role and impact of military leaders from attempting these studies.

This paper aims to address the cellular toxicity of ultra-pure titanium dioxide ($TiO_2$) and zinc oxide (ZnO) nanoparticles (NPs) frequently employed in sunscreens as inorganic physical sun blockers to provide protection against adverse effects of ultraviolet (UV) radiation including UVB (290-320 nm) and UVA (320-400 nm). In consideration that the production and the use of inorganic NPs have aroused many concerns and controversies regarding their safety and toxicity and that microsized $TiO_2$ and ZnO have been increasingly replaced by $TiO_2$ and ZnO NPs (< 100 nm), it is very important to directly investigate a main problem related to the intrinsic/inherent toxicity of these NPs and/or their incompatibility with biological objects. In the present study, we took advantage of the laser-assisted method called laser ablation for generation of $TiO_2$ and ZnO NPs. NPs were prepared through a physical process of irradiating solid targets in liquid phase, enabling verification of the toxicity of ultra-pure NPs with nascent surfaces free from any contamination. Our results show that $TiO_2$ NPs are essentially non-poisonous and ZnO NPs are more toxic than $TiO_2$ NPs based on the cell viability assays.

A series of immoral conducts are repeatedly occurring by some commanders and high-ranking officers in the ROK navy. They are seriously compromising not only harmony and solidarity of the organization, but also pride and morale of members of the service. They seem to be results of the fragile ethical background of the service as well as of failures in military education and training on ethics. This paper sees backgrounds of weak ethical foundations of the navy as follows: the enduring legacies of cultural factors, such as the toxic military culture of the Japanese colonization, dark side of mariners' traditions, the sea-aversive Confucian culture, and unique characteristics in any small organization or society, etc... This paper also suggests the current ethnic systems of the navy are primarily based on responsive measures against misdeeds, rather than fundamental prescriptions for immoral behaviors, in the absence of ethical instrument for warriors. The paper also emphasizes the importance of developing character-based leadership, founded on, above all, respects for human integrity and strong sense of honor. Moreover, the importance of accountability in charging the command, as advocated by the US navy, is also stressed in order to establish a more robust ethic ground within the navy. Based on these analyses, the author proposes that in order to become a stronger and healthier fighting force, the navy needs to make continuous command efforts and organizational innovations to improve ethic principle and moral standard of the service, to strengthen ethics of naval leaders by a robust system of ethical education and training programs, and ultimately to solidify a navy culture in which moral passions and energies are spreading over.

Recently, the population of toxic and/or unusable jellyfish is increasing during summer along the east coast of Korea, causing massive economical and ecological damage to fisheries, nuclear power plant and marine environment. To solve this problem, this study was carried out using jellyfish as a potential soil additive for horticulture. The jellyfish was solidified and homogenized, then mixed with a commercial bed soil. Allium tuberosum ROTH was planted to control bed soil (BS) and jellyfish powder mixed bed soil groups (Mixed bed soil, MBS), and following parameters were measured during five weeks: water content, electrical conductivity and growth of leaves. At the end of the experiment, bacterial community structures of each pot were analyzed by DGGE. The relative water adsorption of jellyfish powder was about 2.5 times greater compared to its dry weight. The water content of MBS group was significantly higher than BS group 6.5 to 14.2%, and the electric conductivity of MBS group was measured around 2.8 dS/m where BS group was resulted average of 1.8 dS/m. However, the leaves of BS group were grown 30% longer compared to MBS group. DGGE analysis of MBS group was shown in high number of phylum Bacteroidetes and increased diversity of Sphingobacteriia compared to BS group. Jellyfish powder as a soil additive surely will be a good candidate as humectant and microbiota stimulator, although there are several obstacles such as high electrical conductivity and residual alum salt which used for solidification of jellyfish.
