  • In this study, the behavior of retaining wall composed with soldier pile and steel plate is analysed. The steel guided plate(SGP) method is applied to the site near the riverside in which geotechnical condition results in flood and large deformation. Following the concept of preventing infiltration from huge permeability stratum and decreasing deformation with strengthened stiffness simultaneously, this method is discussed its effectiveness with the instrumentation data. Also the differences of behavior between predicted and detected are investigated with numerical methods. It is found that SGP has a good deal of advantages with regard to balancing between control of permeability and deformation. In addition, it is revealed that SGP can give resonable construction plan for sustaining stiffness for which the sheetpiling method cannot be adopted effectively in waterfront condition.

  • Underground building constructions are recently more important because the ratio of underground area is increasing in the huge and high-rise building construction projects. For reducing the total building construction periods, it is required to reduce not only the over-ground structural work periods but also the underground structural work periods. Therefore, this study is proposed the non-supporting system forms for single face walls in underground building construction by one of the methods for reducing the underground structural work periods and investigated the applicability of the non-supporting system forms by analyzing the case-study in civil construction project. In regard of construction duration, the results of analyzing the case-study showed that the non-supporting system forms are better than the euro forms with soldier system for single face walls in underground building construction. In addition, it is showed that the cost of these two forms is similar and usage the working space and safety in non-supporting system forms are better that those of the euro forms with soldier system, too.

  • The purpose of this study was to research Korean Jowoo-Guan and Chinese Hal-Guan and study transition and symbolism of the birds feather in the cap. The culture of ancient Korea was influenced by North Asia prior to the influence of the Chinese culture, One of the remarkable thing, as the cultural factor of North Asia is the birds worship thought. Korean Jowoo-Guan was derived from the birds worship thought. So in dealing with the plume of Korean Jowoo-Guan, we must recognize Worship to the bird and the symbolical meaning of the bird. The results of study was as follow. 1. Korean Jowoo-Guan was influenced worship to the sun, so it's wearing symbolized the governing class. As the Social development and governing class, the feathering cap was developed to a gold crown, and also the gold crown of Samguk times had been influenced style of North Asia culture. But afterwards the symbolical meaning of the bird was waning, only decorative meaning was remained. 2. Chinese Hal-Guan was warn in Joo-dynasty, but the symbolism of the plume in the cap was not similar to Korean Jowoo-Guan. Chinese Hal-Guan was symbolized bravery of superfluous soldier than Worship to the bird. But afterwards the symbolical meaning of bravery of superfluous soldier was waning, only decorative moaning was remained. 3.

  • It is very important to share tactical information such as video, images, and text messages among soldiers for situational awareness. Under the wireless environment of the battlefield, the available bandwidth varies dynamically and is insufficient to transmit high quality images, so it is necessary to minimize the distortion of the area of interests such as targets. A natural operating method for soldiers is also required considering the difficulty in handling while moving. In this paper, we propose a natural ROI(region of interest) setting and image compression method for effective image sharing among soldiers. We verify the proposed method through prototype system design and implementation of eye gaze detection and ROI-based image compression.

  • This study was performed to investigate the soldiers' preference for meals provided and their satisfaction with military food service. The average daily calorific intake was 3,976 kcal, representing an extra 467 kcal over the 3,500 kcal state as the minimum daily kcal needed for each soldier based on the manual of the Korea Ministry of Defence. The soldiers preferred Korean food to Western food. The soldiers' overall satisfaction was researched in 7 areas such as quality and hygiene. They were pleased with two facts: holiday food is provided occasionally and the food is served quickly. However, they were dissatisfied with two issues: the poor nutritional information of the food, and the low frequency of special meals. The variety of choice needs to be improved and the cooks need to be better trained. When providers plan the food time table, a sensational menu needs to be considered to satisfy the soldiers' taste. To improve the quality of military meal food, new systems aye necessary such as food schedule, nutritional goal and different systems with independent food providing for the company's involvement.

Methods: Subjects of this study consisted of 317 soldiers who had low back pain. Study instruments were Visual analog scale (VAS), the Center for Epidemiological Studies-Depression Scale (CES-D), and adjustment to military life scale. Collected data were analyzed by the SPSS Win 14.0 program. Results: Mean score of pain was 4.16 points, depression was 8.58 points, and adjustment to military life was 69.15 points. The level of pain was negatively related to adjustment to military life (r=-.241, p<.001) and positively related to depression (r=.262, p<.001). There was a negative relationship between depression and adjustment to military life (r=-.442, p<.001). Conclusion: Soldiers who had low back pain experienced higher levels of pain and depression and lower level of adjustment to military life. Therefore, further study is needed to develop and examine a nursing intervention to manage low back pain for them.

  • A portable power supply system for soldiers must be able to supply electric energy corresponding to the power consumption of combat support troops, and have a carrying load in a range that does not impair the combatant's ability to execute operations. In particular, as the total required power of combat equipment increases with the advances in the future soldier system, a portable, lightweight power supply system with high efficiency is essential. A fuel cell has a high energy-to-weight density compared to lithium batteries, which are used mainly as a military power source system. Therefore, it is capable of miniaturization and lightweight, making active R&D to a portable power supply system. In this paper, the characteristics of the fuel cell applied as a portable power supply system, and the R&D trends of domestic and foreign military portable fuel cell systems were investigated. The current status of domestic technology compared to the level of foreign development was analyzed. In addition, future technology development plans are presented based on the consideration factors when developing a portable fuel cell (power supply stability, portability, and cost reduction) so that it can be used when establishing a plan on the development of a portable fuel cell system for the future soldier system.

  • The black soldier fly larvae are able to decompose various organic wastes such as livestock manures and food wastes. We tested whether the quality of the insect derived compost, i.e. larval feces, was comparable to that of a commercial fertilizer. Chemical analysis of Hermetia. illucens compost was suitable as a fertilizer. When the kidney bean (Phaseolus vulgaris L.) was raised on the culture soil treated with the H. illucens compost, the growth of leaf area, total dry weight and leaf dry weight increased significantly. The H. illucens compost is thought to act as an increasing factor of RGR (relative growth rate) from the beginning of growth and also had a great effect on the relative growth rate throughout the late stage of growth. There is high statistical significance between NAR (net assimilation rate) and RGR (relative growth rate), but no significance between RGR and LAR (leaf assimilation rate) of the treatments. In addition, the treatment of H. illucens compost promoted the thickness of leaves from the beginning of growth and the tendency of thickening leaves from the beginning of growth and the effect continued throughout the late period of growth. When mixed with 50% of H. illucens compost rather than 25%, it showed the greater effect on the plant growth.
