Purpose - The purpose of this study was to analyze environmental and labor issues and related norms, which are new trade issues that are expanding in bilateral and multilateral trade agreements, and examine the possible impact of these norms on domestic fisheries policies. Design/methodology/approach - In this study, literature research was used as the main research methods. The comparative analysis of international norms and multilateral trade agreements texts related to the environment, labor and trade were conducted. Findings - The new trade norms in the fisheries sector can be represented by labor and environment issues. Since domestic environmental and labor standards do not fully meet the standards of the multilateral trade agreements, it is necessary to ensure that domestic norms are supplemented and relevant policies are newly established through a review of international law on environment and labor. Research implications or Originality - This study confirmed that international norms related to labor and environment in the fisheries sector are mixed with soft norms and binding norms, and each norm is linked in a multi-layered and mutual way. Such international norms are being strengthened in connection with trade agreements and issues.

1963년 유엔(UN)은 결의로 채택한 '우주법선언'의 원칙 4에서 "우주활동은 유엔헌장과 국제법에 따라 국제의 평화와 안전을 위해서 및 국제협력과 이해를 위해서 행해져야 한다."고 함으로서 우주의 탐사이용은 군사적 목적이 아닌 '평화적 목적'(peaceful purposes)으로 수행되어야 함을 천명하였다. 그리고 1967년 우주조약 제4조와 1979년 달조약 제3조에서 우주의 탐사이용은 1963년 우주법 선언과 마찬가지로 군사적 목적이 아닌 '평화적 목적'으로 수행되어야 함을 규정하고 있다. '우주의 평화적 이용'에 관한 표현이 정부의 성명서나 여러 다자조약들에서 발견되지만 이 용어에 대한 해석이 분분하여 아직 명확한 의미가 정의된 바는 없다. 이 글에서는 '우주의 평화적 이용'이라는 용어가 국제법상 어떠한 의미를 가지고 있는 지를 살펴보고자 하는데, 우선 국제조약에서는 '평화적 이용'이라는 용어를 어떻게 해석하고 있는 지 알아보고, 우주 관련조약들과 결의 및 연성법상 '우주의 평화적 이용'의 의미를 분석하여 보았다. 한국은 2009년과 2010년 두 차례의 실패를 거울삼아 마침내 2013년 1월 30일 자국의 나로호 기지에서 나로호를 발사함으로서 세계에서 11째 스페이스클럽 (space club)에 진입하였다. 중국이 이미 제3의 우주강대국에 진입하였고, 일본도 우주기본법을 바탕으로 우주개발의 군사적 이용의 근거를 마련하였으며, 북한도 계속된 미사일발사와 함께 러시아와 우주 개발 협력 체제를 모색하고 있는 상황들을 고려해 볼 때 한국의 우주개발은 그 어느 때보다 매우 중요한 시기에 처해 있다. 미국이 소련의 Sputnik 1호 발사로 인한 큰 충격으로 교육제도까지 개혁하면서 우주개발에 성공하였듯이 우리도 우주경쟁에서 살아남기 위해서는 전반적인 교육제도의 검토와 우주개발의 인프라 형성에 전 노력을 기우려야 할 것이다. 현재 미래창조과학부가 주도하는 우주개발에 국방부와 공군의 역할을 중시하여 총체적인 국가안보와 관련된 우주개발계획들이 필요할 것이다.

한국에서 시행중인 특별법에 의한 지하안전영향 평가 수행 시, 필수적으로 지하공동의 발생 유무를 조사하여야 한다. 지하공동 발견 시에는 수치해석을 통해서 지하안전성을 평가하도록 규정하였다. 선행 연구를 통해서 소규모 지하공동의 2차원 형상변화를 통한 안전율 기반의 안정성 평가 가능성을 제시하였다. 본 연구에서는 3차원 형상을 고려하여 소규모 지하공동의 영향을 연속체 해석 프로그램을 사용해서 검토하였고, 선행 연구에서 제시한 2차원 해석결과와 비교하였다. 지하공동의 3차원 형상이 구(sphere)형에 가깝게 발견되면, 공동의 크기, 위치 등에 관계없이 전단강도감소기법으로 안전율을 산정하여 평가하는 방법에 무리가 없을 것으로 판단된다. 지표면으로부터의 깊이 2 m 이상, 장축과 단축의 비(a/b)가 2.0 이상인 장대형 지하공동이 연직방향으로 서있는 형상이라면, 전단강도감소기법을 사용한 안정성 평가에 안전율 이외에 파괴양상 파악에도 주의가 필요할 것으로 판단된다. 본 연구의 결과는 지하안전영향평가에 관한 기초 자료가 될 수 있을 것으로 판단된다.

The consequences associated with ships running aground depend very much on the soil characteristics of the sea bed and the geometrical shape of the ship bow. The penetration into the sea bed depends on these factors and the penetration is an important factor for the ship motion because it influences the ship heave and pitch motions as well as the friction between the ship and the soil. In this paper a rational calculation model is presented for the sea bed soil reaction forces on the ship bottom. The model is based on the assumption that the penetration of the ship bow generates a flow of pore water through the grain skeleton of the soil. The flow is governed by Darcy\`s law and it is driven by the pressure of the pore water at the bow. In addition to this pore water pressure, the bow is subjected to the effective stresses in the grain skeleton at the bow surface. These stresses are determined by the theory of frictional soils in rupture. Frictional stresses on the bow surface are assumed to be related to the normal pressure by a simple Coulomb relation. The total soil reaction as a function of velocity and penetration is found by integration of normal pressure and frictional stresses over the surface of the bow. The analysis procedure is implemented in a computer program for time domain rigid body analysis of ships running aground and it is verified in the paper through a comparison of calculated stopping lengths, effective coefficients of friction, and sea bed penetrations with corresponding experimental results obtained by model tests as well as large, scale tests.

Currently in increasing number of urban tunnels with small overburden are excavated according to the principle of the New Austrian Tunneling Method (NATM). Successful design, construction and maintenance of NATM tunnel in urban area demands prediction, control and monitoring of surface settlement, gradient and ground displacement with high accuracy. Use of measured displacement for parameter determination has been researched over the years, and one geotechnical engineering principle has been formed as back analysis. In this paper, back analysis of a ground deformational behavior involving nonlinear behavior is discussed. It is of primary importance to make reliable prediction of deformational behavior for shallow tunnels in soft ground. However, predictions made often prove to be incorrect due to complexity of constitutive law and other relevant factors. Back analysis therefore becomes more important, for it may be used to interpret measured displacement to derive nonlinear material characteristics. The paper shows some example in which a deformational mechanism is studied in the light of inhomogeneous distrubution of Young's module, from which a logic is derived to identify two different types of nonlinear constitutive relationships.

The purpose of this study is to find a root from naturalism to contribute the identity of Korean fashion design in the world which has universality and particularity. The beauty of nature has accumulated in our unconscious-ness, influenced to our unconsciousness, and contributed to make the formative sense. Our consciousness influenced by climate, for example, the sense of softness from soft curve which can feel from the sight of Korean mountain, land the sense of comfort and security from round rock formed by weathering, the sense of thick-ness from cotton to endure cold winter etc. has a tendency to thick and act by nature's law. This tendency made naturalism by Korean climate and linked to the sense of natural-istic beauty and became a important part forming the Korean fashion design. In this study, the researcher found Korean climate is a important factor acting in our consciousness, and influenced the formative sense. The concept of climate which is made our formative sense include topography, climate, soil, plant and so on. This influenced a lot to set up a foundation of Korean fashion design. And the naturalism by Korean climate newly created and developed shape, color, material and design. It is our duty to develope design based on naturalism to secure the competitive power against the world in this period of information and this design is getting important as a high value added method put into Korean culture. Therefore, developing Korean design which shapes the beauty of Korean nature and traditional culture will have a important competitive power in the world. Moreover, it will make a new tradition of Korean fashion culture stagnated by internationally universalized western fashion after the modernization. Also, it will be needed to develop a common design which can be agreed not only us but all the world for the request of these days of international. Therefore, this study contributed to find definite ours and found centripetal point to find the direction of Korean's philosophy and ideology. But this approach, we could secure the competitive power in this period of international and information and determine and develope the Korean fashion as a culture base, leading the world.

RC delay is a critical issue for achieving high performance of ULSI devices. In order to minimize the RC delay time, we uses the CMP process to introduce high-conductivity Cu and low-k materials on the damascene. The low-k materials are generally soft and fragile, resulting in structure collapse during the conventional high-pressure CMP process. One troubleshooting method is electrochemical mechanical polishing (ECMP) which has the advantages of high removal rate, and low polishing pressure, resulting in a well-polished surface because of high removal rate, low polishing pressure, and well-polished surface, due to the electrochemical acceleration of the copper dissolution. This study analyzes an electrochemical state (active, passive, transpassive state) on a potentiodynamic curve using a three-electrode cell consisting of a working electrode (WE), counter electrode (CE), and reference electrode (RE) in a potentiostat to verify an electrochemical removal mechanism. This study also tries to find optimum conditions for ECMP through experimentation. Furthermore, during the low-pressure ECMP process, we investigate the effect of current density on surface roughness and removal rate through anodic oxidation, dissolution, and reaction with a chelating agent. In addition, according to the Faraday’s law, as the current density increases, the amount of oxidized and dissolved copper increases. Finally, we confirm that the surface roughness improves with polishing time, and the current decreases in this process.

이슬람 극단주의 무장단체 이슬람국가(ISIL), 알 카에다(Al-Qaeda) 등은 불특정다수의 시민들이 이용하는 지하철, 백화점 등과 같은 다중이용시설을 공격 대상으로 하고 있어, 그 공포와 두려움이 확산되고 있다. 만약 한국에서 테러리즘이 발생한다면 불특정다수의 시민들이 이용하는 다중이용시설을 그 대상으로 할 가능성도 제기되고 있기에, 이와 관련한 점검이 시급한 실정이다. 그러나 다중이용시설의 개념이 다의적이고 그 범위가 광범위하여 테러리즘에 대비하기 위한 점검에 한계가 발생하고 있다. 이 연구에서는 다중이용시설 관련법의 검토를 통한 해결책을 모색하였다. 우선, 다중이용시설 관련법은 국가기관의 필요에 의해 제정되어 그 개념과 범위가 매우 포괄적이다. 이로 인하여 대(對)테러리즘과 관련한 점검의 범위에 대한 논란이 발생할 우려가 있다. 다음으로, 테러리즘이 발생할 경우 주무부서가 명확하지 않아 권한과 책임의 문제도 발생할 수 있다. 이러한 한계를 극복하기 위하여 다중이용시설의 범위를 재설정함과 동시에 주무부서의 역할에 대한 논의를 하였다.

Deep learning is another field of artificial intelligence (AI) utilized for computer aided diagnosis (CAD) and image processing in scientific research. Considering numerous mechanical repetitive tasks, reading image slices need time and improper with geographical limits, so the counting of image information is hard due to its strong subjectivity that raise the error ratio in misdiagnosis. Regarding the highest mortality rate of Lung cancer, there is a need for biopsy for determining its class for additional treatment. Deep learning has recently given strong tools in diagnose of lung cancer and making therapeutic regimen. However, identifying the pathological lung cancer's class by CT images in beginning phase because of the absence of powerful AI models and public training data set is difficult. Convolutional Neural Network (CNN) was proposed with its essential function in recognizing the pathological CT images. 472 patients subjected to staging FDG-PET/CT were selected in 2 months prior to surgery or biopsy. CNN was developed and showed the accuracy of 87%, 69%, and 69% in training, validation, and test sets, respectively, for T1-T2 and T3-T4 lung cancer classification. Subsequently, CNN (or deep learning) could improve the CT images' data set, indicating that the application of classifiers is adequate to accomplish better exactness in distinguishing pathological CT images that performs better than few deep learning models, such as ResNet-34, Alex Net, and Dense Net with or without Soft max weights.

Background: As South Korea enters an aged society, the government has emphasized the need for a soft landing of the older adults into the community after the acute and recovery periods under a national policy of "community care." However, the institutionalization of community rehabilitation services to implement this is insufficient. Japan had already entered an aged society when the Long-Term Care Insurance System was introduced in 2000. Thus, the case of Japan's institutionalization of the system is expected to have implications for us in supplementing a suitable system for the aged society. Objects: This study compared the institutionalization process of the Long-Term Care Insurance System in South Korea and Japan and the services currently being implemented in each country. Methods: To examine the institutionalization process and services of the system, related legal rules and regulations, government reports, and articles were reviewed. To examine the operation status of the system, statistical data provided by each country's government were analyzed. Results: Japan recognized the importance of community rehabilitation even before the enactment of Long-Term Care Insurance. Thus, community rehabilitation services, such as home-visit rehabilitation and health facilities, were already stipulated in the law. Under such institutional legacy, Long-Term Care Insurance was able to establish a service system, which balanced welfare and health-related services, including various types of services with enhanced rehabilitation functions. In South Korea, rehabilitation policies were not much considered in the process of institutionalizing the system; thus, it was composed mainly of services focusing on care and recuperation. Conclusion: In order to realize community care, rehabilitation services need to be developed in Long-Term Care Insurance System in various forms such as home-visit services, daily services, short stay, and facility services.
