본 논문에서는 남북경협을 재개하기 위한 토대로서 북한에 대한 인식을 비롯한 현재의 상황을 적시하였으며, 남북경협의 필요성과 의의에 대해 확인하였다. 이와 더불어 과거 남북경협이 갖는 한계도 함께 지적하였다. 제도가 갖는 한계로서 소위 3통 문제뿐만 아니라 외부적 여건에 취약한 구조가 그것이다. 그러나 이러한 문제들뿐만 아니라 내부적 문제도 존재하고 있음을 확인하였다. 대표적으로 통치행위로 인한 남북경협이 중단될 수도 있다는 사실이다. 특히 개성공단의 전면적 중단의 상황에서 그 누구도 일정한 안정성과 예측가능성을 가지지 못하였다는 점은 우리 법률이 갖는 한계를 명확하게 보여준다. 이와 관련하여 논문에서는 위법한 통치행위의 경우, 단순히 “통치행위는 불법행위가 되지 않는다”라는 결론을 이끌 수는 없다는 점을 통치행위를 입법행위와 동치시키는 논리구조를 통하여 위헌인 법률로 인하여 국민의 기본권인 재산권 침해하였다면, 그에 따른 책임도 부담하여야 한다는 결론을 도출하기 위하여 노력하였다. 추가적으로 지난 5·24조치와 관련된 우리 대법원 2013다205389 판결에서 확인할 수 있는 바와는 달리 개성공단 전면 중단의 경우에는 개성공단에 진출해있는 모든 기업들의 가동중단과 철수를 포함하고 있다는 점을 지적하였다. 그렇기에 개성공단의 중단과 관련한 국가배상책임이 긍정될 수 있는 가능성이 있다고 판단하였다. 긴급명령과 같은 수단은 최후적인 방법이 되어야 한다. 그렇기 때문에 3통의 문제를 해결하기 위한 입법적 방법과 함께 발생되어서는 안 되겠지만, 발생할 수도 있는 향후의 경협중단과 관련된 일련의 절차를 법률화하는 것 역시 향후 남북경협의 활성화의 전제가 될 것이다. All Koreans will have a consensus on peace on the Korean Peninsula. However, there is still a negative view on the inter-Korean economic cooperation. This view leads to the denial of the justification itself in promoting inter-Korean economic cooperation. However, the Moon Jae-in administration has declared that it will maintain its independent inter-Korean cooperation policy within the framework of international sanctions against North Korea. From the perspective of the theory of peace economy, it is clear that the promotion of economic cooperation provides an important engine for peace. This is because if the inter-Korean economic cooperation expands, the negative variables from “North Korea risk” will decrease and be suppressed to a minimum. In addition, through inter-Korean economic cooperation, North Koreans will learn directly or indirectly about capitalist economic logic, and can play a major role in correcting their distorted perceptions of South Korean society. However, it is time to discuss the effectiveness of these laws with the Kaesong Industrial Complex shutdown in 2016. In particular, the impact of the Kaesong Industrial Complex shutdown in 2016 was attributable to the decision of the Korean government. Based on this necessity, the thesis confirmed the necessity, significance, and limitations of the inter-Korean economic cooperation, and dealt with who should bear the responsibility for damages caused by the total suspension of the Kaesong Industrial Complex as a guarantee for the stability of the inter-Korean economic cooperation.

Objectives: Employee exposure record refers to a record containing information about environmental(workplace) monitoring or measuring of a toxic substance or harmful physical agent. The aims of this study were to examine problems related to exposure records and provide some amendments to the Korean Industrial Safety & Health Act for the effective management of chemical substances under the law. Methods: This study performed a literature search and review on legal provisions related to exposure records of a number of different countries, including Korea, the USA, Japan, EU, Germany, and the UK. They were compared and investigated and the amendment of articles was suggested. Results: The results of this study were provided as suggested amendments to the related act. There were a variety of ways of improvement, including a 30-year retention period and the introduction of new access methods, contents, transfer, and maintenance methods. All exposure data elements have to be standardized, including reference to a similar exposure group(SEG), sampling strategy, and circumstances of exposure(e.g., date, shift length, use of personal protective equipment, etc.). The SEGs are described by process, job, task, and environmental agent. Conclusions: This study is expected to provide for the amendment of the related act in order to ensure effective management of exposure records and is helpful for solving the cause and result of occupational disease by keeping exposure records according to the Industrial Safety & Health Act.

It is prescribed in the provision of Article 2 of Architects Regulation that the definition of "Field Administration" is: to supervise and affirm whether the building, architectural equipment, or structure is being constructed in accordance with contract documents to guide and direct quality and progress of work, and its safety management. Since the "Provision of Architects Regulation" was enacted in 1962, it has been compulsory to conduct field administration for any building of certain size by a qualified licensed architect to affirm whether the building was constructed in accordance within the legal parameters of the contract documents. However, the intention of the above legislation has become nominal since the government mitigated provisions for duties and requirements of construction engineers, construction progress and safety in October 1998. There have been constant disputes among many parties since the limitation of responsibility for field administration was never clearly established legally even after the enactment of provisions on field administration. The objective of this study is to build transparency in the construction process by clarifying the limit and extent of field administration. I hope that this study can establish a basis to promote national competitiveness in the construction industry.

이온성 액체를 함유한 고분자 전해질의 전기화학적 특성

Ionic liquids have being investigated for many applications including reaction solvent, separation medium, and electrolytes of supercapacitor and solar cell. Since ionic liquids are liquids which are entirely composed of ions, they can have high ionic conductivity. They are also non-volatile and non-flammable, and exist as liquid state over a wide range of temperature compared with organic solvents commercially used. Therefore, when they can be used as electrolytes, it can make more safe battery than commercial one. In this study, a series of ionic liquids was synthesized and ionic liquids were soaked into microporous P(VdF-HFP) membrane, the polymer electrolytes were also prepared. Microporous membrane was prepared by phase inversion method. Their thermal stability was preformed by TGA and their electrochemical properties were evaluated with ionic conductivity, electrochemical stability and cyclic voltammogram.

Contemporary, architecture calls for a wide range of surface textures and treatments. A surface compatible with the architecture's design may vary from a glass-smooth finish to one requiring special sculptured ornamentation. These surface require many different types of form sheathing and lining. The purpose of study development new design form and made elaborateness shape. Easy to used in field that architecture finish material not used expect effective reduce of working hours, personnel expenses, architecture finish material, cost, through this study, we have figured out the best mix proportion for durability and gloss ability of glossing exposure concrete.

The flexural analysis of thin-walled I-section composite beams under uniformly distributed load using the first order shear deformation theory is studied. A general analytical model applicable to the flexural behavior of a thin-walled composite beam is developed. This model is based on the Vlasov's theory modified first order deformation theory to analyze the flexural behavior of I-section made of laminated composite materials. All possible laminate stacking sequence including symmetric and anti symmetric cross-plies, symmetric and anti symmetric angle-plies are considered. Governing equations are derived from total potential energy principles. The maximum vertical displacements of simply supported composite beams are calculated for all stacking sequences, and compared to the results by other results and ABAQUS. It is found that the present analysis successfully predicts the bending behavior of composite beams.

Architectural Design is the creative solution represented by a licensed architect for his/her client's intention and request. It consists of contracts and construction documents (drawings and specification) to draw up an estimate of a project and construction method. Therefore, the quality of architectural design influences its construction quality. This research is to bring architects' attention to their professional ethics and awareness of their responsibility to raise the quality of architectural design. This research further facilitates international contract business among nations based on the proposals for improvement of related regulations. The subject of this research is to achieve national competitiveness. flexibility of regulated system with safety assurance and quality improvement, and ultimately to stir up the architects' expressional motivation for creative design.
