The U.S.-Korea fisheries relationship was concluded on the legal basis of Korea as a distant-water fishing nation and U.S. as a coastal state, and aiming effective conservation, management and rational utilization of the marine living resources. The existing two legal problems on U.S.-Korea fisheries relationship are the pelagic driftnet fishing on the high seas and trawl fishing in the Bering Sea. The results and countermeasure discussed on the positive legal systems of both countries which simultaneously rationalize the conflicting standpoints each other are as follows : 1. For the sake of rational conservation and utilization of the high seas fishery resources, an international organization composing of all the coastal states and fishing nations concerned must be established, and it shall be shall be more desirable to manage the resources by the international joint control system than by the bilateral agreements between the countries concerned. 2. The U.S.-Korea Fisheries Agreement being based on the MFCMA was concluded by mutual understanding between both countries. Accordingly, no protest exists against legal status of the Agreement because it has acted as a customary norm in keeping fisheries relationship between both countries within the U.S. EEZ. 3. The existing fisheries legislative system of Korea is insufficient to support development of the industry satisfactorily. Therefore a special legislation, for example $\ulcorner$Distant-water Fishery Promotion Act$\lrcorner$, is required. And a perfect legal system for effective conservation and management of fishery resources must be established.

The 3 Northeast Asian countries of Korea, Japan and China have been stricter to each other than to other countries of out-region in air liberalization. The prominent reason of this intra-regional protective policy in air transportation seems to be the difference in competitive strength of their national flag carriers. As the 3 countries realize the importance of their mutual cooperation in the region, since China grows to be one of the leading economies in the world and the intra-regional trade and visitors increase tremendously, they are now taking the policy of intra-regional air liberalization more vigorously than before. Especially air cargo liberalization is easier than air passenger liberalization because they realize that the development of open economy is based on free flow of logistics regardless of the competitiveness of their national flag carriers. As Korea is the leading country in the region to promote air liberalization, this paper reviews the importance and growing trend of air cargo, analyzes current air liberalization policy between Korea, Japan and China and the initial effects of open sky in the routes of Shandung-Korea, and suggests the new policies of air liberalization to promote free flow of air logistics.

3GPP(3rd Generation Project Partnership)-WLAN(Wireless Local Area Network) interworking refers to the utilization of resources and access to services within the 3GPP system by the WLAN UE(User Equipment) and user respectively. The intent of 3GPP-WLAN Interworking is to extend 3GPP services and functionality to the WALN access environment. We propose an efficient mechanism for the setup of UE-initiated tunnels in 3GPP-WLAN interworking. The proposed mechanism is based on a secret key which is pre-distributed in the process of authentication and key agreement between UE and 3GPP AAA(Authentication, Authorization Accounting) server. Therefore it can avoid modular exponentiation and public key signature which need a large amount of computation in UE. Also the proposed scheme provides mutual authentication and session key establishment between UE and PDGW(Packet Data Gateway).

The proposed Trans-Pacific Partnership (TPP) is a free trade agreement among 12 Pacific Rim countries whose joint gross domestic products (GDPs) account for 36 percent of world GDP and whose mutual trade accounts for approximately 24 percent of world trade. As for most proposed free trade agreements (FTAs), trade economists have provided ex ante computable general equilibrium (CGE) estimates to predict the trade, employment, and real per capita income effects of this agreement, such as ITC (2016). This paper-intended to complement these studies-examines the potential impacts of TPP beyond such traditional CGE estimates, taking a broader economic, governance, and historical perspective. First, we contrast these traditional CGE trade and welfare estimates that treat all firms within an industry as homogeneous with more recent CGE analyses that allow firms' productivities to be heterogeneous. We show that the latter models' trade predictions are much more consistent with ex post empirical evidence of average trade effects of FTAs. Second, empirical evidence now strongly confirms the existence of FTA "contagion." We review this evidence and show that predictive models of the evolution of FTAs indicate that the TPP should be formed. With China now having formed 12 FTAs and negotiating five new ones (including a sixteen member Asia-Pacific FTA), the United States would likely face considerable trade diversion without the TPP. Third, we examine empirical evidence on the likely further economic growth implications of FTAs by reducing firms' uncertainty over trade relations and trade policies. Fourth, we examine empirical evidence on the additional impact of FTAs on consolidating democratic institutions in countries. The TPP would likely help consolidate some of the less mature democracies. Fifth, we examine empirical evidence on the reductions of conflicts (and enhanced peace) between countries owing to the formations of FTAs. We conclude the paper noting that the potential net benefits to member countries of the proposed TPP extend well beyond the real income gains to households based upon traditional CGE models.

Until now, the domestic construction market has been formed focusing on new construction and reconstruction in the apartment industry. Recently, however, the remodeling market for old structures have shown a tendency towards land shortage and land price increases in the major cities: the reinforcement of regulations regarding reconstruction; expenditure reduction and the solving of environmental problems by regarding old structures is pursuing low costs and maximum efficiency. The interest in remodeling is increasing, however, remodeling has not been successfully initiated in the apartment division for a reasonable period of time. Consequently to acquire mutual agreement for remodeling from the residential occupants. In order to evaluate profitability, it is necessary to set priorities and reasonable criteria for remodelling and to this end, it is also required to assess each fact of remodelling in view of both customers and supplied. Thus, a sample apartment housing complex was analyzed for geographic location, surrounding environment floor area ratio, site area, number of households, number of stories and unit area and thereupon, its remodelling profitability was analyzed to select an effective remodeling method as an alternative case for apartment house owners and remodelling.

Although various home services are developed as increasing the number of home devices with wire and wireless connection, privacy infringement and private information leakage are occurred by unauthorized remote connection. It is almost caused by without of device authentication and protection of transmission data. In this paper, the devices' secret value are stored in a safe memory of a smartphone. A smartphone processes device authentication. In order to prevent leakage of a device's password, a shadow password multiplied a password by the private key is stored in a device. It is proposed mutual authentication between a smartphone and a device, and session key agreement for devices using recovered passwords on SRP. The proposed protocol is resistant to eavesdropping, a reply attack, impersonation attack.

In the plant EPC project, the procurement work can be considered as the most important part that affects the success or failure of project as it has the closest mutual influence in every execution process of the project. Procurement takes up generally 60% ~ 70% of the entire project budget and the current trend of plant EPC project becoming larger in scale and a variety of process technology being applied. So, it is needed to identify the risks that are expected to occur according to the stages of procurement work, namely, proposal stage, manufacturer selection and purchasing agreement stage, expediting the process management of manufacturer stage, inspection stage and logistics & transportation stage. The management of observation and control of the risks should be performed with the response techniques which are 'avoid',' transfer'and' mitigate'.

A numerical analysis and experimental investigation of microstrip meander lines is given with reference to their low-pass amplitude and phase characteristics. The analysis features the inclusion of equivalent circuit models for bends to analytical equations for the muntual couplings between lines. The numerical simulation is efficient and is not constrained by the number of the coupled lines. Experimental results for 4=coupled meander lines, which are in good agreement with the simulation, are included.
