One of the issues with clayey soils, particularly those with significant quantities of organic matter, is the creep settling problem. Clay soils can be strengthened using a variety of techniques, one of which is the use of stone columns. Prior research involved foundation loading when the soil beds were ready and confined in one-dimensional consolidation chambers. In this study, a particular methodology is used to get around the model's frictional resistance issue. Initially, specimens were prepared via static compaction, and they were then re-consolidated inside a sizable triaxial cell while under isotropic pressure. With this configuration, the confining pressure can be adjusted, the pore water pressure beneath the foundation can be measured, and the spacemen's lateral border may be freely moved. This paper's important conclusions include the observation that secondary settlement declines with area replacement ratio. Because of the composite ground's increasing stiffness, the length to diameter ratio (l/d) and the stone column to sample height ratio (Hc/Hs) both increase. The degree of improvement varies from 12.4 to 55% according to area replacement ratio and (l/d) ratio.

Purpose: We should prepare proper medical service for disaster control as South Korea is not free from terrorism and war, as we experienced through the two naval battles of the Yeonpyeong, one in 1999 and the other in 2002, the sinking of Cheonan in 2010, and the attack against the border island of Yeonpyeong in 2010. Moreover, North Korea's increasingly bellicose rhetoric and mounting military threats against the world demand instant action to address the issue. The aim of this article is to describe our experience with three patients with combat-related gunshot and explosive injuries to their extremities and to establish useful methods for the management of patients with combat-related injuries. Methods: Three personnel who had been injured by gunshot or explosion during either the second naval battle of the Yeonpyeong in 2002 or the attack against the border island of Yeonpyeong in 2010 were included in our retrospective analysis. There were one case of gunshot injury and two cases of explosive injuries to the extremities, and the injured regions were the left hand, the right foot, and the right humerus. In one case, the patient had accompanying abdominal injuries, and his vital signs were unstable. He recovered after early initial management and appropriate emergency surgery. Results: All patients underwent emergent surgical debridement and temporary fixation surgery in the same military hospital immediately after their evacuations from the combat area. After that, continuous administration of antibiotics and wound care were performed, and definite reconstructions were carried out in a delayed manner. In the two cases in which flap operations for soft tissue coverage were required, one operation was performed 5 weeks after the injury, and the other operation was performed 7 weeks after the injury. Definite procedures for osteosynthesis were performed at 3 months in all cases. Complete union and adequate functional recovery were achieved in all cases. Conclusion: The patient should be stabilized and any life-threatening injuries must first be evaluated and treated with damage control surgery. Staged treatment and strict adherence to traditional principles for open fractures are recommended for combat-related gunshot and explosive injuries to the extremities.

The purpose of this study is to examine the main features of South Korea's New Northern Policy and to make some suggestions for cooperation with neighboring countries' initiatives. The New Northern Policy encompasses the whole of Eurasia, but the starting development area would be the border region of the Korean Peninsula. In this viewpoint, this study examines the Belt and Road Initiative of China, the New Eastern Policy of Russia and the Steppe Road Initiative of Mongolia, and presents the characteristics, problems and some implementation strategies of the New Northern Policy. Apart from the future possibilities of the regional cooperations that include North Korea, it would be necessary for South Korea to secure and expand the possible opportunities for "Korea-China-Mongolia-Russia" cooperation. In order to create a close cooperative environment with North Korea in the future, it would also be necessary to build a maritime route, with port development around major border regions on the Korean Peninsula, including Russia, and to develop the port-railway intermodal transportation system with neighboring countries. South Korea need to actively cooperate with neighboring countries to develop the new Eurasia logistics routes would be more favorable to the Korean Peninsula in preparation for the time when the North Korean nuclear issue will be resolved.

As exchanges between countries become more active, new threats such as drugs, illegal imports of food and medicines, and terrorism are present all over the world. From this, increased border security that protects people's safety is becoming a new issue. The activities of special purpose dogs that detect these threats in advance are becoming very important. One of the obstacles in securing superior individuals is musculoskeletal disorders which interfere with the work of special purpose dogs. In order to search for genes associated with these genetic disorders, we conducted genomic analysis using linkage disequilibrium information and investigated genetic characteristics to know heterozygosity and inbreeding status in the population. In this study, two breeds (Malinois, Shepherd) of army dogs and three breeds (Malinois, Shepherd, Retriever) from public databases were used for comparison. The 170K SNP marker panel was used for this study. In the principal component analysis, it was confirmed that clusters were formed for each breed. The number of effective populations differed for each cultivar, but this was due to the difference in numbers of individuals for each breed used for the analysis. The results of heterozygosity decay analysis showed that heterozygous alleles decreased with each generation. In the army dog group, if the population number is maintained properly, the frequency of allele genotype will not decrease significantly.

It is recent trend that every countries are opening their border in the name of liberalization of contemporary era. Shipping is not exceptional and it used to be said as international business. Therefore, co-operation and openness of maritime sectors between regional countries is required to utilize resources that each countries can manage. It can be done by employing their vessels in other countries' short sea area. However, there are some problems to implement this practices, here cabotage is centre of issue. Each countries do not open their sea in order to protect their national interests in sovereignty. But, it should be opened if co-operation between each countries work well and properly. To achieve true maritime co-operation, countries as Korea, China and Japan in Northeast Asia region should have understanding for the opening of cabotage. In order to make things work well, it can be done by the lessons from EU and American cases. Therefore, it should be clarified such as market scale to provide cabotage trade, employment as well as interested parties, and technical safety matters as well as environmental standards. Then cabotage matters can be smoothly resolved between three countries in Northeast Asia region.

Despite continuous efforts to redraw the boundaries between art and culture, the conventional concept of originality has persisted in approaches to the practice of contemporary art. In the discourse of originality, various forms of lesser arts that employ the method of replication have been referred to as kitsch, or "rear-guard," the opposite of avant-garde. This categorization points to the contested issue regarding the oppositional relation between modernism and mass culture. With its easily accessible content and financial affordability, mass culture has become both an irresistible attraction and a most powerful threat to modernism. This threat has instigated a discursive system that has situated mass culture as a cultural other of modernism. Taking the marginalized category of kitsch as the area of contention, this paper examines a discursive repression of kitsch. It analyzes the conceptual framework that defends originality and autonomy in art and, conversely, degrades kitsch as an inferior and dangerous cultural category. Greenberg'S concept of kitsch as a by-product of industrialization evolved into the criticism that advocates the autonomy of art. The Frankfurt School scholars, particularly Theodor Adorno and Max Horkheimer, practiced comparable cultural critiques. Focusing on mass culture such as film, radio, and television, instead of art works, they critically analyzed the system of mass culture and theorized the negative implications of the ubiquitous presence of kitsch. Some critics, on the other hand, perceived the growth of mass culture as opening possibilities in cultural development. Walter Benjamin and Harold Rosenberg asserted the socio-cultural dynamics of mass culture underlining the potential for continual transformation in reality and in the subject. They acknowledged that technological advances changed the condition of creation and enabled unmediated interactions between media. By scrutinizing conflicting views on kitsch, this paper intends to reassess arts that draw "the forces of the outside."

Representing the future of language is a very difficult but important issue, because it signifies a world of language different from the present; at the same time it secures the identity of the present language between the future changed language and the present one. This paper examines the linguistic world of dystopia, focusing on the "Fuji-no-shima" and "Gentoshi" of Yoko Tawada. First of all, "Fuji-no-shima" shows that, for Yoko Tawada, who was crossing the border between German and Japanese as a bilingual writer, the accidental Fukushima nuclear power generation in 2011 was accepted as the destruction of verbal order between signifiant and $signifi{\acute{e}}$, due to physical changes caused by radiation leaks. "Gentoshi" tells that human ties can be maintained through language activities that can capture multiple meanings, even in a world where traditional language order is destroyed through a policy of seclusion. From the above discussion, the novel Distopia, can actually be called Utopia as long as humans rely on the power of various languages to sustain it.

The North Korea nuclear issue is now posing a serious security threat to the Korea and Northeast Asia. Accordingly, the South Korean military is pushing for the introduction of long-range air-to-surface flights and the development of domestic nuclear facilities that can precisely hit North Korea headquarters building and nuclear facility even hundreds of kilometers above the border. In this paper, we removed the cable braid for securing the weight of the missile among several design elements for long-range air-to-surface missile development and estimated and analyzed the resulting performance. The possibility of braid removal was analyzed in terms of crosstalk inside the cable and CS114, RE101 of MIL-STD-461F.

Ieodo is a submerged rock within a Korea's Exclusive Economic Zone(EEZ) in the East China Sea with its most shallow part about 4.6m below the sea level which has no specific rights for the EEZ delimitation. The United Nations Convention on the Law of the Sea (UNCLOS) stipulates that any coastal state has the rights to claim an EEZ that stretches up to 200 nautical miles from its shore, except where there is an overlap with a neighboring country's claims. Korea claims that Ieodo is within its EEZ as it sits on the Korean side of the equidistant line and the reef is located on the Korea section of the continental shelf. China does not recognize Korea's application of the equidistance principle and insists that Ieodo lies on its continental shelf. According to UNCLOS, Ieodo is located in international waters, rather than one country's EEZ as the two countries have failed to reach a final agreement over the delimitation of the maritime border. This study seeks to understand the evolution of the People's Liberation Army Navy(PLAN) strategy as main obstacles for the EEZ delimitation between Korea and China. PLAN's Strategy evolves from "coastal defense" to "offshore defence", since the late 1980s from a "coastal defence" strategy to an "offshore defence" strategy which would extend the perimeter of defence to between 200 nm and 400 nm from the coast. China's economic power has increased It's dependence on open trade routes for energy supplies and for its own imports and exports. China want secure Sea Lane. PLAN's "offshore defence" strategy combines the concept of active defence with the deployment of its military forces beyond its borders. China's navy try to forward base its units and to achieve an ocean going capability. China's navy expects to have a 'Blue Water' capability by 2050. China insists that coastal states do have a right under UNCLOS to regulate the activities of foreign military forces in their EEZs. China protests several times against US military forces operating within It's EEZ. The U.S. position is that EEZs should be consistent with customary international law of the sea, as reflected in UNCLOS. U.S. has a national interest in the preservation of freedom of navigation as recognized in customary international law of the sea and reflected in UNCLOS. U.S. insists that coastal states under UNCLOS do not have the right to regulate foreign military activities in their EEZs. To be consistent with its demand that the U.S. cease performing military operations in china's EEZ, China would not be able to undertake any military operations in the waters of South Korea's EEZ. As such, to preserve its own security interests, China prefers a status quo policy and used strategic ambiguity on the Ieodo issue. PLAN's strategy of coastal defence has been transformed into offensive defence, Korea's EEZ can be a serious limitation to PLAN's operational plan of activities. Considering China'a view of EEZs, China do not want make EEZ delimitation agreement between Korea and China. China argues that the overlapping areas between EEZs should be handled through negotiations and neither side can take unilateral actions before an agreement is reached. China would prefer Ieodo sea zone as a international waters, rather than one country's EEZ.

Papers in FTA research have mostly focused on the legal interpretation of the FTA treaties. In this research, more focus was put on the customs laws and related cases delivered in the U.S. federal courts, by which we can analyze the Korea-U.S. FTA in more practical manner to derive the enterprises' solutions to cope with the disputes of FTA preferential duty. The Tariff Act of 1930 is the U.S. customs law to govern FTA preferential duties. The administrative practices with customs duties are coordinated with the FTA rules. The most controversial issue in the U.S. customs law lies in the classification of imported goods for imposition of the customs duties, based on Harmonized Tariff Schedule of the United States. It was found that the U.S. federal courts had been quite favorable to the CBP(U.S. Customs and Border Protections) in litigation with the private importers and exporters. The reason seems to be that the CBP has been dealing with the customs cases so many times, accumulating much experience in execution of the U.S. customs laws, which is likely to make their decisions on customs duties almost free of errors. Therefore, the Korean exporters need to collect the CBP's past cases on the denial of preferential treatment on imported goods and be fully informed of the CBP's policies on the FTA preferential duty treatment.
