This research deals with the PLAN's capabilities and its implication for regional security, and suggests some measures for maritime security cooperation among regional states. China has began to focus its national strategy more on 'rising as a new maritime power' since the 18th Party Convention in November 2012. Chinese new strategy aims at building a strong navy, contributing economic prosperity and national security, and thus elevating its prestige in international society. Most of all, building a strong navy is the foremost task at this time, and that is why the PLAN has the priority for military modernization. Chinese new maritime strategy could cause naval arms race in East Asia and aggravate maritime territorial disputes among concerned parties. It is the time for regional states to discuss some measures to build confidence, such as arms control of naval weapons, establishment of multilateral maritime security mechanism, and foundation of regional security regime, thus enhancing regional maritime cooperation.

Purpose - Based on the existing retail policy literature, this study aims to compare Korea with foreign countries, to propose better ideas for the Korean retail market. Research design, data, and methodology - It is necessary to analyze the existing retail regulations after categorizing them into several groups, depending on why governments have regulated retailers and the background for the retail policy. Results - Given that Korean retail regulations have focused on protecting conventional markets, comparing the retail policy objectives of South Korea and foreign countries is difficult. Conclusions - It is necessary examine how to protect independent stores, irrespective of store locations across the country. Rather than limiting the distance between traditional markets and the projected locations suggested by large retailers, various factors such as store size limit, opening and closing times, below-cost selling, land use planning, and competition tests are needed to protect small stores. Further, centralized authority for store operations should be delegated to local governments, to tackle the aggressive expansion of retail giants. To protect independent stores, political background is among the most important factors.

Purpose - The general objective of this study is to explain the governance mechanisms of relational exchanges by considering both economic and relational factors. As regards the relationship between opportunism and governance mechanisms, opportunism was hypothesized as being positively related to the use of the authority mechanism, and negatively related with use of the trust mechanism. Research design, data, and methodology - Purchasing relationships between original equipment manufacturers (OEMs) and their component suppliers were chosen as the empirical setting. Purchasing specialists in each company, who interact regularly with suppliers and have the major responsibility for managing the exchange relationships with suppliers, were used as the respondents for this study. A mail survey methodology was employed to collect data in the final field survey. Results - As predicted, opportunistic behavior is found to be negatively related to the use of the trust mechanism and positively related to the use of the authority mechanism. Therefore, the result supports the proposed hypotheses. Conclusions - By integrating research streams, this study contributes to the marketing discipline by improving our understanding of when and why different mixtures of governance mechanisms are used.

The purpose of this study is to discuss how to introduce micro degree for innovation in convergence education in our university. To this end, the background of the introduction of micro and nano degrees and domestic and foreign applications were reviewed. The reason why the rate of students completing the multi-degree was low was that the credits required for graduation were higher than that of other domestic universities, and the difficulty of the courses offered in the convergence major did not match the students. In order to reduce the burden of students learning convergence subjects while acquiring new knowledge and skills, the introduction of a micro degree is considered to be an alternative to the current convergence education.

LNG carrier is a special-purpose vessel to transport natural gas (NG) from the place of origin to each consuming country. To increase the capacity of canying LNG carrier, the natural gas is conveyed as a state of liquid called LNG (Liquefied Natural Gas) during a voyage because the total volume of NG is surprisingly reduced when it is cooled down to $-162^{\circ}C$. That is why the design of insulation of the carriers is important to protect LNG from the external heat invasion, and it has been a great challenging subject for several decades in the shipbuilding industry. For this ultimate goal, the boil-off rate (BOR) needs to be accurately estimated during a voyage. Therefore, the goal of this study is to propose a numerical method for estimating the BOR of LNG for given insulation containment subject to external temperature conditions during voyage.

Variable length coding (VLC) has been used in many well known standard video coding algorithms such as MPEG and H.26x. However, VLC can not be processed parallelly because of its sequentiality. This sequentiality is a big barrier for implementing a real-time software video codec since parallel schemes can not be applied. In this paper, we propose a new fast VLD (Variable Length Decoding) method based on the probabilistic distribution of symbols in VLC tables used in MPEG as well as H.263 standard codecs. Even though MPEG suggests the table partitioning method, they do not show theoretically why the number of partitioned tables is two or three. We suggest the method for deciding the number of partitioned tables. Applying our scheme to several well-known MPEG-2 test sequences, we can reduce the computational time up to about 10% without any sacrificing video quality

The most salient and discussed features of speech production in agrammatic aphasia are the omission and substitution of grammatical morphemes. Cross-linguistic studies have shown that the pattern of omission/substitution is not random but occurs in a systematic and highly constrained way. Although these descriptions are important, they do not explain why all grammatical morphemes are not equally impaired. Friedmann and Grodzinsky (1997) proposed the Tree-Pruning Hypothesis (TPH) to account for these patterns of sparing and loss. The TPH claims that in an agrammatic representation, an impaired functional node is underspecified, thus allowing inappropriate affixation to occur. Additionally, whenever a node is impaired, all nodes above it will also be impaired. Using four types of narratives collected from two Korean agrammatic patients, We test the claim that the impairment in agrammatism is based on such hierarchical representation. It was found that these patients consistently produced appropriate grammatical morphemes that are higher in a syntactic tree than the impaired morphemes. The finding that an intact node exists higher than an impaired node refutes the TPH.

Introduction of PLM in domestic shipyards is being retarded as ship PLM has yet to firm up return of investment and process integration. To implement a ship PLM system, it is required to share ship CAD model data in various design and manufacturing environments. Lightweight CAD models provide a promising solution for sharing CAD models in the product life cycle, which can expedite implementation of ship PLM in domestic shipyards in the near future. Compared to proprietary CAD models, it is easy for lightweight CAD models to be interfaced with various application systems and be connected to manufacturing information. In this paper, the reason why lightweight CAD models are necessary to implement a ship PLM system is addressed and current implementation results are introduced.

The unit modular method is one in which unit modules are prefabricated at a factory and then constructed at a construction site. That is why an important process, transporting unit module, is added in this method. The purpose of this study is to analyse the load for transporting unit module. The results of the analysis of the driving experimental runs revealed that a maximum load of 15 kN was applied on adapter block type A and a maximum load of 25 kN on adapter block type B. These loads were recorded at the points in the road test when the low-bed trailer was driving through unstable sections of the test such as stopping, restarting, passing over a speed bump or taking a left turn at speed.

Recent scandals of milk additives in several developing countries provoked controversy about quality issue of dairy products, grapping academic attention to the dairy supply chain. In this paper, we first focus on moral hazard problem of self-interested entities about the quality across the dairy supply chain, due to unobservable and unverifiable quality management efforts of all entities - including dairy producers, stations, and a final producer - and high inspection cost for the quality. Based on the identified moral hazard problem, we understand why the adoption of IoT-based tracking systems about quality produced from each entity is a must, different from RFID-based tracking systems.
