  • Innovation is considered as key to ensure continuous advancement and firm progress in any field. Robotics, with no exception, has gained triumph and approval based on its strength to address divers range of applications as well as its capacity to adapt new ways and means to enhance its applicability. The core of novelty in robotics technology is the perpetual curiosity of human beings to imitate natural systems. This desire urges to continuously explore and find new feet. In the past, contemporary machines, in different shapes, sizes and capabilities, were developed that can perform variety of tasks. The major advantage of these developments was the ability to exhibit superior control, strength and repeatability than the corresponding systems they were replicating. However, these systems were rigid and composed of hard an underlying structure, which is a constraint in bringing into being the compliance that exists in natural organisms. Inspiration of achieving such compliance and to take the full advantage of the design scheme of biological systems compelled researchers and scientists to develop systems avoiding conventional rigid structures. This ambition, to produce biological duos, needs soft and more flexible materials and structures to realize innovative robotic systems. This new footpath to craft biological mockups facilitates further to exploit new materials, novel design methodologies and new control techniques. This paper presents an appraisal on such innovative comprehensions, conferring to their design specific importance. This demonstration is potentially useful to prompt the novelty of soft robotics.

  • This study, in order for perceiving the mechanical attribute followed by the explosive spalling of high strength concrete material under high temperature and evaluating capacity of endurance of material, targets understanding capacity of endurance of material such as explosive spalling in high temperature, temperature by thickness of clothing, transformation extent, transformation speed and displacement, stocking the maximum load based on the Allowable Stress Design Method. As a result of experimenting the explosive spalling attribute of high strength concrete material, the one possibly causing serious damage is the 50 MPa concrete. In all aspects of 60 MPa concrete, explosive spalling happens. Especially, it is hazardous enough to reveal all the iron bar. All explosive spalling is intensively concentrated on the surface of concrete for the first $5{\sim}25$ minutes, which urges for the explosive spalling protection action. As a result of evaluating the structural safety by the transformation of high strength concrete, while beam assures the fire safety meeting regulation, 60 MPa shows the dramatic increase of transformation, which only counts 84% of safety. In a column, both the concrete exclusion and excessive explosive spalling are concentrated upper part of column, which brings about the dramatic transformation, so it only meets the 50% of safety regulation. Likewise, in 80, 100 MPa concrete which was never experimented considering the condition of domestic structural endurance stocking devices, the faster collapse is expected.

  • Southeast Asian region cruise market is expected to be stable or grow in the near future depending on the region's economy. Star Cruises company, which has entirely dominated the regional market since 1998, has attempted to expand beyond traditional cruise routes in Southeast Asian region and develop new markets in Thailand and Dubai. Such a situation urges Korean shipyards to study on Southeast Asian region based cruise ships. This study is to suggest directions for planning of interior spaces of Southeast Asian region based cruise ships. In order to accomplish this purpose the market situation is analyzed and the adequate ship's tonnage(70,000grt class) is decided. According to mission-based design process the sizes of standard staterooms are set up first and then the sizes of the important structural parts of ship are calculated. Through analyzing the 26 cruise ships of 70,000grt class the kinds, locations and sizes of public rooms are grasped. And we inspect 4 cruise ships of Star Cruises, which are now being operated in Southeast Asian region to understand design characteristics of interior spaces.

  • Should the Korea Maritime Police Agency (KMPA) be a comprehensive, multi-functional organization for a unique on-scene service at sea, as in the case of the U.S. Coast Guard, or should it be simply a water police agency, confining its mission only to law enforcement? The argument about enlarging or limiting KMPA's function has been and will be repeated. In this paper, Lee Sangjib highlights the internal and external issues facing KMPA, stemming partly from deficiencies of its struggles for advancement of the organization and partly from shortcomings of political support for it. In this regard, he urges KMPA to practise a scientific management system for maximizing cost-effectiveness of its administrative resources and for maintaining its identity and characteristics as a lead maritime agency. In addition, he also suggests that KMPA adopt the Total Quality Management System for quality improvements in services and greater efficiency in its organization structure to meet the future competition in the changing political and legal environment. He further recommends the proactive, non-regulatory 'Prevention Through People' program, pioneered by the U.S. Coast Guard, as a way of changing KMPA's existing lopsidedly legalistic culture. He concludes by providing a 6-point vision statement for KMPA from the standpoint of favoring enlarging the function of KMPA.

  • The brain necrosis induced by radiation therapy (RT) is an uncommon pathology of brain. A case of spontaneous hemorrhage at necrotic brain is also rare. A 52-year-old man who had nasopharyngeal carcinoma and had been treated with RT, presented with gait disturbance, dizziness, ataxia, dysarthria, and dysphagia. Magnetic resonance imaging (MRI) demonstrated progressed radiation necrosis of pons, and spontaneous hemorrhage at the site of necrosis. The hematoma was diminished by conservative treatment. However, the patient's neurologic symptoms did not recover. Two years later, spontaneous bleeding recurred at necrotic brain. His neurologic symptoms worsened. One year later, his neurologic symptoms were more progressed. He showed severe dysphagia, profound weakness and respiratory failure. This case provides the description of relapsed spontaneous hemorrhage and medullary dysfunction caused by pontine necrosis and progressed post-radiation injury, complicated with hemorrhage, and urges caution in that the necrotic brain tissue may be vulnerable to bleeding.

  • Even though the number of CO poisoning casualties caused by unintended idling for the vehicles equipped with keyless ignition systems is more than 70, the problem still remains unsolved and became social issue in the US, and Senates introduced the bill which urges NHSTA to make regulation for this accordingly. To meet market safety needs and the regulations, we decided to provide automatic shut-off system very soon. In this paper, we would like to describe how to validate vehicle shut-off timing including defining required tests and case selections considering vehicle condition, garage/room size and temperatures with several assumptions. We believe that safe implementation of the shut-off function is possible via this methodology and the results. As NHTSA must be interested in shut-off timing, the methodology can be enhanced and conclusions could be reflected highly in the future regulation in case we continue this study with NHTSA or any other 3-rd party institutes.

  • The 11th Congress of the Vietnamese Communist Party(VCP) held in January 2011 was the forum to reconfirm the gradual reform. By analysing the documents submitted to the Congress, it can be realized that the VCP's reform policy reveals the compromise between conservative and progressive perspectives by "the Socialist-oriented Market Economy". The VCP proposes to proceed the balanced reform for the sustainable development by multi-sector economy to achieve the basis of the modern state by 2020 on the one hand and also urges to strive against "the peaceful evolution" to defend the socialist regime from abroad as well as within the party itself on the other hand. In personnel structure of the Central Committee and Politburo, this term of the Party still keeps the balance of the localities and sectors of the society. No big change was in the selection of top leaders, as almost of them were promoted slightly in the existing echelon of the Politburo. On the prospect of the reform process Vietnam will continue the reform as gradual as before.

  • Culture as a source of identity, as Edward Said says, can be a battleground on which various political and ideological causes engage one another. It is not mere individual cultivation or private possession, but a program for social cohesion. Sensitively aware that a national culture should be independent from Europe, Walt Whitman enacts a new form of literature by placing different cultural values against Old World tradition. His interest in autochthonous culture originates from his deep concern about national consciousness. He believes that literary taste directed toward highly-ornamented elite culture is an obstacle to cultural unification of a nation. In order to represent American culture of the common people, Whitman incorporates a lot of cultural material into his poetry. Since he believes that America has many respectable writers at home, he urges people to adjust to their own taste instead of running after foreign authors. Whitman differentiated his poetry from previous literary models by disrupting the established literary norms and reconfiguring cultural values on the basis of American ways of life. In his comment on other poets, he concentrates on the originality and nativity of poetry. By claiming that words have characteristics of nativity, independence, and individuality, he envisions American literature to be distinguished from British literature in literary materials as well as in language. Whitman s language is composed of a vast number of words that can fully portray the nation. He works over language materials in two ways: reterritorialization and deterritorialization. Not only does his literary language become subversive of the established literary language, but also makes it possible to express strength and intensity in feeling.

  • This thesis urges the change of the education system of popular music for globalization of K-POP in a longer point of view Korean popular music has developed not only musically but also sound quality itself. Moreover it became popular in a global scale in the name of K-POP. However, it is still limited to idol music, and numerous issues related to the lack of musical talent are emerging Even though the routine of birth and death of several idol groups and singers are still repeated. Recently, the skills of artists enhanced due to audition TV shows but still it's not enough. Under this situation, it is not appropriate to rely on audition TV shows and Entertainment Management companies for picking up talented artists. Therefore, like Classic or Traditional music, schools concentrated for popular music must be founded. If this become enabled, young students going to entertainment companies or to unqualified but expensive private institutes will disappear. Moreover, it can prevent students from lacking behind in their academic activity. In addition, a reformation should be done education colleges for raising popular music educators
