US 8th Army in the attack on the Western Front was a situation that was frustrated by the 13th Corps Communist army. To this time support this, goals that have been granted to the US 1st Marine Division that initiated the attack in Mupyonri direction, lack the potential to achieve was not decisive. It was a operation specific erroneous judgment that occurred because there was no one accurately grasp the battlefield of the situation the wrong UN Forces Command. Tactical victory can be to maximize the operation outcomes. However, there is no possible failure of the operation is to expand the tactical success. This is because the failure of the operation, because directly linked to the success or failure of the war. Tactical victory can be to maximize the operation outcomes. However, operation specific failure is not it possible to expand the tactical victory. Therefore tactical success of the US 1st Marine Division, can not compensate for operation specific failure of the United Nations Forces Command. However, Chinese Communist Army 9th Corps is obsessed only victory of tactics to annihilate the US 1st Marine Division, by being fixation to the Chosin whole area, it was not possible to run a operational operation. Therefore tactical success df the US 1st Marine Division, Chinese Communist Army 9th Corps is to extinguish the ability to increase the number of the 13th Corps of the Western Front, 8th Army US have contributed to have escaped the crisis. In addition, the US 10th Corps while maintaining the combat force, by an important role to withdraw through the sea, was able to complement the misjudgment of the operation.

The purpose of this study is to examine the military look, which is one of the most popular fashion trends in the 1996 women's fashion. Military look is that imitates or reinterprets the Army uniform which is functionally useful. After World War 1 , military look appeared in the women's fashion which is functionable tailor suits style, ankle-length skirt, pants or boiler suits for work wear, overcoat against the cold, and there was an attempt to introduce a National Standard Dress. In the middle of World War II, there was a similiar circumstance in women's military fashion. There were functionable tailor suits, knee-length skirt, pants or siren suits for work wear. And the Utility Dress was nationally recommended. In addition, the regulations were introduced to control the materials and styles used for some clothes. In the 70s, as the resistance movement as counterculture began to wear Army look which was army-uniform or army caps with 'US ARMY' logo and badges, and became very popular among the youth. In the 90s, military look has got one of the fashionable fashion themes with revival of Neo- Hippie look. Not only street fashion but also high fashion designer selected the trend for '96A/W The characteristics of the military look are khaki colors or camouflage prints, epaulets, big outpockets with flap, golden buttons and army belt. As I examined, during the World War I and ll, women wore the military look because of shortage of goods and work or service, and it was recommended by government. Though the military look in 70s, began by the resistance movement, at least it became a popular fashion. Military look in 90s, does not have inner symbolic meaning or ideology but it only represents fashion trend and revival fashion.

Objectives: To validate a critical-size mandibular bone defect model in miniature pigs. Materials and Methods: Bilateral notch defects were produced in the mandible of dentally mature miniature pigs. The right mandibular defect remained untreated while the left defect received an autograft. Bone healing was evaluated by computed tomography (CT) at 4 and 16 weeks, and by micro-CT and non-decalcified histology at 16 weeks. Results: In both the untreated and autograft treated groups, mineralized tissue volume was reduced significantly at 4 weeks post-surgery, but was comparable to the pre-surgery levels after 16 weeks. After 16 weeks, CT analysis indicated that significantly greater bone was regenerated in the autograft treated defect than in the untreated defect (P=0.013). Regardless of the treatment, the cortical bone was superior to the defect remodeled over 16 weeks to compensate for the notch defect. Conclusion: The presence of considerable bone healing in both treated and untreated groups suggests that this model is inadequate as a critical-size defect. Despite healing and adaptation, the original bone geometry and quality of the pre-injured mandible was not obtained. On the other hand, this model is justified for evaluating accelerated healing and mitigating the bone remodeling response, which are both important considerations for dental implant restorations.

The purpose of this study is to propose a model that can polish and improve the ROK (Republic of Korea) Army's records management policy in a new records management environment by analyzing the context of policy implementation. In this study, two distinct and different policy cases were analyzed using different models for policy analysis such as the case of the records management system of the ROK Army with the street-level bureaucracy model and the case of the archives personnel within the ROK Army with a Policy Network model. The results from the comparative analysis with both cases state that the street-level bureaucracy model has limitations in analyzing even a policy implementation case when multiple actors are involved. At the same time, a network policy model is useful in identifying the problematic points that need improvement in the case. Based on these results, some improvements for effective records management in the ROK Army were proposed. This study follows the approach of the two distinctive case studies from the perspective of policy science-a view that no archive researcher has ever explored before.

Non-commissioned officers reach 80% of the 6,500 recruitment target, and 88% of the workforce is operated, about 9,500 less than the quota. To solve this problem, RNTC was tested and operated for about four years since 2015. And it was run directly by the Army in 2020. However, the Army has not solved the problem of RNTCs in college. While maintaining RNTC in universities, measures were needed to cope with the decrease in school-age populations, but the army did not address them. The universities tried to achieve two goals: securing students and increasing employment rates, which failed to meet the expectation. This was mainly because students only from particular departments were selected. And this was not what the army aimed to achieve through RNTC. After analyzing the cause of this phenomenon. the problem turned out to be the erroneous perception of RNTC to the general public. In order to eradicate this problem, there needs to be more effective promotion by the Army, and some improvements are also needed in terms of RNTC's selection process. In this paper, we find and describe the problems of the system itself. If this problem is solved, we will be able to not only satisfy the needs of both the Army and the universities, but also produce good non-commissioned officers through the RNTC system.

A unique lightweight string truss deployable bridge assembled by thin-walled fiber reinforced polymer (FRP) and metal profiles was designed for emergency applications. As a new structure, investigations into the static structural performance under the serviceability limit state are desired for examining the structural integrity of the developed bridge when subjected to unsymmetrical loadings characterized by combined torsion and bending. In this study, a full-scale experimental inspection was conducted on a fabricated bridge, and the combined flexural-torsional behavior was examined in terms of displacement and strains. The experimental structure showed favorable strength and rigidity performances to function as deployable bridge under unsymmetrical loading conditions and should be designed in accordance with the stiffness criterion, the same as that under symmetrical loads. In addition, a finite element model (FEM) with a simple modeling process, which considered the multi segments of the FRP members and realistic nodal stiffness of the complex unique hybrid nodal joints, was constructed and compared against experiments, demonstrating good agreement. A FEM-based numerical analysis was thereafter performed to explore the effect of the change in elastic modulus of different FRP elements on the static deformation of the bridge. The results confirmed that the change in elastic modulus of different types of FRP element members caused remarkable differences on the bending and torsional stiffness of the hybrid bridge. The global stiffness of such a unique bridge can be significantly enhanced by redesigning the critical lower string pull bars using designable FRP profiles with high elastic modulus.

"History is a mirror" means that we should be prepared for the threats of enemies through learning from repeating history. Currently South Korea is facing various provocations, including North Korea's nuclear weapons and missile s. For the protection of the life and property of its people, South Korea should regard North Korea as a main enemy and be fully prepared for the threats. The Korean War was a war between well-prepared North Korea and ill-prepa red South Korea. After Liberation, North Korean army incorporated the Chinese Communist army, placed battle equi pment with the support of the Soviet army, and finished corps-level training while South Korea at that time did not finish battalion-level training. In wartime and peacetime, an army should improve military security by concealing its own information and find its enemy's information. North Korea carefully prepared for the war, collecting information about the organization, deployment and operation of the South Korean army. South Korean army failed to cope with it and had hard times in its early battles. In this paper, I will emphasize the importance of military security, focusing on the Battle of Gaeseong, the early part of the Korean War.

It is reported that the expression level of MLL3 in gastric cancer tissue highly correlates with tumor progression. However, whether MLL3 genetic variants are associated with the risk of gastric cancer remains unclear. In this study, we conducted a genotyping analysis for MLL3 in 314 cases of gastric cancer and 322 controls from the Chinese Han population. 4 SNPs (rs6943984, rs4725443, rs3800836, rs6464211) were selected for the present analysis. We found 2 SNPs (rs6943984, rs4725443) of MLL3 gene were significantly associated with the risk of gastric cancer : the rs6943984 with the minor allele A and rs4725443 with the minor allele C revealed strong associations with increased gastric cancer risk [P < 0.001, OR=1.97, 95% CI=1.48~2.64 and P <0.001, OR=2.23, 95% CI=1.54~3.24]. Haplotype analysis of the four SNPs showed that haplotype A-T-A-C, G-T-G-C, and G-C-A-C increased the risk of gastric cancer (P <0.001, P=0.18, and P<0.001, respectively), while haplotype G-T-A-C significantly reduced the risk of gastric cancer (P <0.001). We concluded that MLL3 variants are significantly associated with gastric cancer risk. Our results for the first time provided new insight into susceptibility factors of MLL3 gene variants in carcinogenesis of gastric cancer of the Chinese Han population.

Tetrapod has been used as the armor blocks of most rubble mound breakwaters constructed in Korea. The Hudson formula has been widely used in the design of breakwater armor blocks in Korea. In the present study, we calculate the load and resistance partial safety factors of the Hudson formula for Tetrapod armors. The partial safety factors were calculated for the typical breakwater cross-sections of 12 trade harbors and 8 coastal harbors in Korea. The mean and standard deviation of them were also calculated. The mean values were compared with the partial safety factors of US Army (2006). The load and resistance factors are slightly smaller and larger, respectively, than the US Army values. However, the overall safety factors obtained by multiplying the load and resistance factors are close to the US Army values. The result of the present study could be used as the basic data to propose authorized partial safety factors in the future.
