The legislative cosponsorship network shows the legislative process of the National Assembly through the relationship between the members of the National Assembly formed by cosponsorship. This study focused on the library bill proposed during the 19th National Assembly term, and conducted the cosponsorship network analysis, the centrality analysis of actors of the National Assembly, and a subgroup analysis of keyword-centric networks. As the result of the study, the library bill's cosponsorship network was segmented according to political parties, and lawmakers who played an intermediary role in close proximity to other political party members had an important influence on the network. When restructured into a keyword-oriented network, the network structure segmented into political parties improved as members of different parties shared the same keywords and formed subgroups. Based on the results, it was suggested that a strategy for spreading and sharing policy issues based on core keywords rather than library legislation, centered on lawmakers who play a mediating role between parties, is needed to activate library legislation.

In this paper, we present an energy-efficient base station operation with base station sharing in wireless cellular networks. Firstly, cost functions are modeled related with the amount of energy usage and traffic load. We use game theory and formulate an energy bill game, where the players are the service operators which are operating base stations and their strategies are the bill of their base station energy consumption and hand-over traffic load to the others service operators. We show that the global optimal performance in terms of minimizing the energy costs is achieved at the Nash equilibrium of the formulated energy bill game. Simulation results confirm that the proposed approach can reduce the energy bill of the service operator, and show the relationship between the energy cost saving and various parameters.

A recursive relationship is a relationship among entities of the same class. N : M recursive relationships can be used to represent bills of materials. A bill of materials is a special data structure that occurs frequently in manufacturing applications. This data structure is a hierarchy. Most business dimensions have a hierarchical structure. In this study, a design of a hierarchical dimension of the bill of materials type is carried out. As with other N : M relationships, an intersection table that shows pairs of related rows is created, and this table is transformed into a dimension in the OLAP(OnLine Analytical Processing) model. This transformation consists of two tasks: (1)replacing the first column of the intersection table with the lowest level of the dimension: and (2)replacing the second column of the table with the only upper level of the dimension. A case multidimensional information system using the hierarchical dimension is also developed.

As the era of the 4th Industrial Revolution has progressed and the information and communication technologies have developed dramatically, the cyber threats will gradually become more intelligent and sophisticated. Therefore, in order to take systematic and prompt action in case of an accident while preparing measures against the threat, the role of intelligence agency is important. However, Korea is having difficulty in responding to the threats due to the lack of support for the national cybersecurity bill or the amendment bill of the National Intelligence Service. In this paper, I examine the cybersecurity function of the intelligence agency, the recent debate trends, and implications for the role of intelligence agency in our current situation. And then I intend to suggest some measures such as concentration on information gathering and analysis, enhancement of cyber threat prediction and response capacity, and strengthening of legal basis as a way to establish the role of intelligence agency for reinforcement of cybersecurity performance system.

Recently, supply chain attacks against nuclear facilities such as "Evil PLC" are increasing due to the application of digital technology in nuclear power plants such as the APR1400 reactor. Nuclear supply chain security requires a asset management system that can systematically manage a large number of providers due to the nature of the industry. However, due to the nature of the control system, there is a problem of inconsistent management of attribute information due to the long lifecycle of software assets. In addition, due to the availability of the operational technology, the introduction of automated configuration management is insufficient, and limitations such as input errors exist. This study proposes a systematic asset management system using SBOM(Software Bill Of Materials) and an improvement for input errors using natural language processing techniques.

This article aims at analysing the practical problems of FOB and CIF terms relating to Incoterms$^{(R)}$2010 in case of L/C transactions and presenting the defending measures against them. According to Incoterms$^{(R)}$2010, FOB and CIF terms are to be used only for sea or inland waterway transport and require the seller deliver the goods on board the vessel nominated by the buyer at named port of shipment. So if FOB and CIF terms will be used in sea transport under L/C transaction, the seller should ship the goods on the nominated vessel and present the shipping document indicating "on board vessel" to the issuing bank but the parties agree to present the received bill of lading according to special condition on L/C which is" received bill of lading are acceptable". In practical transaction, FOB and CIF terms are usually used in aircraft cargo, container cargo or multimodal transport. these facts are a violation of Incoterms. Incoterms$^{(R)}$2010 which regulated that FOB and CIF terms may not be appropriate where goods are handed over the carrier before they are on board the vessel for example goods in container. These transactions are a temporary expedient and breach of Incoterms in the international trade which must be corrected as soon as possible.

본 연구는 MRP(Material Requirement System) 시스템의 기본 요소인 BOM(Bill of Material)의 효과성 분석을 목적으로 한다. BOM은 부품의 구성 관계를 나타내는 표로서, 근자에는 모듈화의 개념이 도입된 Modular BOM이 제시되고 있다. Modular BOM은 부품의 구성 관계를 모듈화 함으로써 이들을 보다 편리하게 관리하고, 기존에 사용되어 오던 구조형 BOM의 불편함, 단점 등을 보완한다. 본 연구는 기존의 구조형 BOM과 modular BOM을 데이타베이스 관리면에서 분석함으로서, 모듈화한 BOM이 데이타 관리면에서 지니는 효과성을 분석하였다. 데이타 관리의 효과성 분석은 BOM 데이타 관리면에서 지니는 효과성을 분석하였다. 데이타 관리의 효과성 분석은 BOM 데이타베이스의 제품구성을 관계형 데이타베이스의 레코드 (또는 tuple)로 표현 함으로서, 특정 부분품으로 구성된 완제품들을 나타내기 위해 필요한 레코드 수를 기초로 하여 수행되었다. 이상의 논리에 근거하여 본 연구는 다음과 같은 데이타 관리 관점에서 분석한다. 1. 제품구성 표시를 위한 BOM 데이타베이스의 구성 레코드 수의 비교, 2. 새로운 제품의 추가나 기 제품의 제품구성 변경에 따른 갱신의 용이성 본 연구에서는 분석의 편의를 위하여 BOM 구성이 레벨을 무시한 단순형태의 2단계 BOM을 분석 대상으로 한다. BOM데이타 베이스 관리의 효과성은 제시된 레코드 수에 기초하여 데이타베이스의 규모와 변경 용이성의 측정 모형을 수립하고, 이들 모형을 modular BOM과 구조형 BOM에 적용함으로서 수행 되었다.

The active use of the container vessel has brought with it high speed and reduced transit time ; however, the system of delivering the goods via B/L at the destination has lagged behind technical advances, becoming a burden to today's international traders, especially consignees and/or importers. More recently the sea waybill(SWB), that is to say an ocean-type AWB, has come on the scene. In Europe and the USA the use of SWB has increased significantly, but has also left room for improvement due to its short history of use. However, Recently, more attention is paid to SWB as a means to solve the B/L Crisis is getting more and more serious. In addition, due to its non-negotiability, the sea waybill could easily be replaced by messages sent between the interested parties by Electronic Data Interchange. With the paper document, transfer of title is fulfilled by transferring the original bill of lading to the buyer of the goods. However, in an electronic environment this is difficult to replicate. A number of solutions have been investigated, including using an electronic bill of lading, by controlling changes in title to goods through irrevocable, but transferable instructions to the carrier, or by appointing an independent electronic data registry, or replacing the bill of lading with a sea waybill, which is non-negotiable. The purpose of this study is to investigate some problems which may hinder SWB from coming into wide use and to analyse how to solve problems due to introduction of electronic sea waybill.

In 25th April. 2008, the Korea legislature gave advance notice on the Revision Bill of Commercial Law in Insurance Division in partial, one of which is the principle of utmost good faith to be codified in accordance with the effectuation of the Revision Bill enforcement. For this, even though the disclosure duty is not included in the Revision Bill, it should also be discussed in relation to the principle of utmost good faith because it is based upon the principle of utmost good faith and forms a part of utmost good faith. In Marine Insurance industry in Korea, there are the sections and the clauses in relation to the English governing law included in the Policies and the Clauses used in Korea and, also, they still come into effect for the Korea Courts' judgements. So. we, Korea, should carefully pay attention to the trend of English courts' leading case, academic world and insurance industry on the disclosure duty in U.K. This study is thus based upon sections 17 and 18~20 of the Marine Insurance Act 1906 and sections 651, 652 and 655 of Commercial Law in Insurance Division, which appear throughout this work. The objective of this work is to analyse the duty of disclosure on Korean and English Insurance Laws including cases cited in this work, comparing the differences resulted from the analysis of the two countries‘laws and legal cases.
