The purpose of this paper is to explore the relationship between the number of relocation and volition of soldier's service based on system thinking perspective using a causal loop analysis. Research adopting system dynamics concerning on the volition of soldier's service and relocation has not been studied yet. Causal loops are analyzed and evaluated by focusing on soldier's military performance, stress of family members and family members' welfare service. Result of this study is that soldier's periodical movement is indispensable factor maintaining military life. Most of the married soldier's life conditions are worse than ordinary people. As the number of relocation is increasing family of soldier's stress is increased by anxiety for welfare conditions is supposed to relocate. The number of movement to another place of soldier's children is more than two times and the result of learning achievement is worse than ordinary students. This kind of stress can influence the married soldier's military performance and stress. So the welfare service should be expanded to an official residence, education, facility, district network service and so on.

This study aims to help improving the quality of military food service as identifying awareness, attitudes and satisfaction of cooking soldier on their duties and providing basic data to find out alternatives on the basis of identified data. The analysis results are described as follows. For general demographics of subjects, sergeants consisted of the highest percentage of population as 38.8% in terms of the rank. For educational background, the percentage of graduates or college students was 82.5%. For the characteristics of job performance of cooking soldier, those who studied entirely different courses from cookery and became to work as cooking soldier were 92(89.3%) of total subjects. For the question why they became to work as cooking soldier, the response that they didn't know the reason showed the highest percentage as 63.1%. Those who selected cooking soldier because they were interested in cookery were only 25.2%. And 94.2% of the population had no certificates related to cookery. With respect to awareness on training period to carry on duties as cooking soldier, 3 months were selected as the most appropriate period as 36.9%. In accordance with research on job percentage of cooking soldier, 'cleaning and washing' consisted of the highest percentage among ordinary duties as 16.8%, followed by 'cooking' as 12.3% and 'food dispensing' as 11.8%. This study suggests as follows on the basis of the results of this researches. Cooking soldier requires expertise, but the privates with short period of service are discharged from military service when they are accustomed to their duties and become experts. Accordingly, the cooking soldier system could not achieve more than its ordinary performance. Therefore, it is required to post non-commissioned officers who can serve for a long time as the special resources.

In natural conditions, the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), colonizes in warm temperate regions, and is active in Korea from May through October. Information on black soldier fly rearing, which is affected by seasonal factors in Korea, is limited. This species colonizes and oviposits in a wide variety of decomposing vegetable and animal matter. For mass rearing of black soldier flies, the egg deposition methods are dependent on sunlight and oviposition sites. In this study, we investigated the substrates and oviposition sites preferred by black soldier fly in artificial rearing system. Our results showed that as black soldier flies prefer mating under sunlight, they prefer ovipositing at sites where adequate sunlight and food substrate are available. Further detailed research is required to develop methods for artificially rearing black soldier fly throughout the year in Korea.

The Female workforces opened the combatants which was not allowed so far including the artillery in the army, air defense, and etc. to the woman soldier in 2014. I exceeded 10,000 people in 2015 and it is in the plan to be expanded to 4,450 officers, 6,374 noncommissioned officers in 2017. A navy is the plan which selects the woman officer to board a submarine since 2017 and which I board over 3,000 t level in a submarine. But the institutional supplementation about this is insufficient although the woman soldier increased depending on the policy's decision. The role of the woman soldier was expanded and it was the time when the system developmental about the woman soldier management which is consistent with the future war aspect will have to be guaranteed, and the clear standard including the post circulation to the starting in advance of the woman soldier and human resource expansion and treatment, and etc. is required. I supplement the current regulation which I am applying as man soldier Army and the same standard although the woman soldier and man soldier Army has a difference and I analyze the phenomenon and the developmental solution should be suggested about the woman soldier people management.

This study attempted to find out the moderating effects of ego-resilience in the relationship between soldier's military stress and military adjustment. The datas were collected from 321 soldier of military from questionaries in October, 2013. The results were as follows. The soldier level and academic career had no impact on the military adjustment. Military stresses of soldier had greater impact on the military adjustment than other factors. Ego-resilience also had positive impact on the military adjustment. This study demonstrated that ego-resilience of soldier had moderating effect in the relationship between military stress and military adjustment. This study verified that to improve the capability of military adjustment of soldier it is as important to attention soldier's inside thing, ego-resilience as environment things. Finally, the authors remarked the limits of this study and the suggestions for the further research directions.

This study examined the antecedents and outcomes of leader-member exchange (LMX) quality in the Korean Army platoons. Although a number of studies have devoted substantial attention to the application of the LMX theory in various organizational settings, there has been no effort to verify or to apply the model to a military situation. In this paper, we tried to build an integrative LMX model to apply to the Korean army. We developed, on the basis of literature review, an integrative framework describing the factors affecting the LMX quality, LMX quality outcomes and the moderators of LMX quality-outcomes. Then we collected data from the 404 lieutenant-soldier dyads. The analysis of the data showed that 1) interpersonal variables (perceived similarity and liking of soldier) and LMX quality were significantly related, 2) LMX quality and outcome variables(soldier's performance, job satisfaction, and morale) were significantly related, and 3) the relationship between LMX quality and soldier's performance were strongly significant when task challenge is high but nonsignificant when task challenge is low, while there were nonsignificant or weekly significant relationships between LMX quality and soldier's performance when task challenge is moderate. The results are basically coinciding with the previous research, except that, with the low challenge tasks, the LMX quality did not affect soldier's performance, which seems to be due to the directive leadership style of the lieutenants. The theoretical and practical implications and future research directions are discussed.

The black soldier fly, Hermetia illucens, has a worldwide distribution in the tropics and warm temperate regions and is active in the Korea from May through October. This species colonize a wide variety of decomposing vegetable and animal matter and oviposits in a variety of decomposing materials. In this study, how the black soldier fly pupation, adult emergence and mating rate changed with season at the artificial rearing system was investigated. The black soldier fly larvae and pupae were reared under laboratory condition ($27^{\circ}C$, 60% R.H.). In this study, under the laboratory condition, pupation and adult emergence were not influenced by season, but the data shows definitely different mating numbers throughout whole year. The time of the day is changed with seasons and it influence to mating on artificial rearing. To culture the black soldier fly throughout the year in Korea needs a more deep study under the artificial rearing system.

Most studies of the black soldier fly, Hermitia illucens, widely distributed throughout Southeast Asia and America focused on the use of larvae for recycling various organic materials and feed for fish and livestock. To recognize the instars of the soldier fly's larvae, we examined the number of exuviae originated from each larva from 1st instar to pupa. The weight and the head capsule width of the black soldier fly larvae also confirmed that the black soldier fly was passed through 6th instars. In addition, we found that the black soldier fly larvae had a well developed mandibular-maxillary complex, similar to those reported from the larvae of scavengers including Odontomyia cincta, Neopachygaster maculicornis, Ptecticus brunettii and Stratiomys ruficornis.

The aim of this study is to develop a model of layering system for future soldier system. Future soldier has been supposed to carry various digital devices embedded into the combat uniform. The combat uniform must be developed to be fit to soldier's body and movement, and can be felt comfortable to soldier. The Uniform must be studied in ergonomic and physiological component because it is different from the present one. It has many devices inside, so there are some unknown barriers to set the devices on to the body. For making the ergonomic aspect of future combat suits clear, the movement of the body was researched. The size of arms(3 parts), torsos(4 parts), and legs(3 parts) of people were measured by movement. Many dots were drawn on the testees' bodies every 3cm. Each time they made compulsory poses, the distances between dots be measured and analyzed. For making the physiological aspect of future combat suits clear, the thermo-map and sweating map of body were made. The 3 maps - movement, thermo and sweating- were overlapped. The devices for future soldier were arranged on the overlapped map considering relations between devices. The final layering system developed on the arrangement of devices.

The purpose of this study was to determine the possibility of black soldier fly (Hermetia illucens) as a animal feedstuff. Insect resources have been widely recognized that it exhibits its own biological activity by whole body or its metabolic intermediates. To accomplish this, its general and biological activities were measured. The present study was conducted to compare antioxidant activity of black soldier fly larva, pupa and grasshopper by examining radical scavenging activity using DPPH (2,2 diphenyl 1-picryl hydrazyl). DPPH radical scavenging activity was conducted on the EtOH, MeOH, H2O fractions of black soldier fly larvae. Results showed that black soldier fly pupa on the H2O fraction contained the highest DPPH radical scavenging activity among the samples. FRAP assay are more suitable methods to evaluate antioxidant activity of black soldier fly extracts. Among the samples, the FRAP value showed higher antioxidant activity in the extracts from black soldier fly pupa extract on H2O fraction. These results suggest that black soldier fly larva and pupa extract has antioxidant activity and its fractions can be utilized to develop functional feedstuff.
