This study examined the determinants of export performance of small and medium sized manufacturing companies in Korea. Depending on the existing research, taking entrepreneurship and product differentiation capabilities as antecedents of export performance. In addition, the product differentiation capabilities examined whether the role of the mediating effects between entrepreneurship and export performance. Thus, the purpose of the study is look at the integrated model of entrepreneurship, product differentiation capabilities and export performance building and their relationship. On 152 domestic companies, empirical analysis was performed. Empirical analysis was conducted using the PLS(Partial Least Square). And analysis tools were used SmartPLS2.0. In the results of the analysis, risk tolerance and innovativeness of small and medium sized manufacturing businesses, entrepreneurs and product differentiation competence have positive impact export performance in both. Product differentiation capabilities also confirmed that it have a positive impact on the export performance of small manufacturing export enterprises. In analysis of the mediated effect in product differentiation capacity showed a significant mediated effect between innovativeness and export performance. But mediated effects did not indicate a significant risk tolerance. these results suggests the need to actively pursue innovation that more product differentiation capabilities required in export companies to small and medium-sized manufacturing. In other words, when attempting to highlight product differentiation, based on innovation, rather than risk tolerance. In terms of analyzing the mediated role of product differentiation capabilities, this study has theoretical implications for the future research to look at the antecedents of export performance from the perspective of dynamic capabilities and competitive advantage. Also, practical implications in this regard as the innovativeness and taking risks to all important to CEO of small manufacturing enterprises but, stranger in the foreign market competition environment, the role of innovation product is required on raising product differentiation capabilities are presented.

As modern society changes toward knowledge based society, the patent policy and professional manpower need to be changed because interest and importance about patent, trademarks, intellectual property right and copyright of business secret are increasing. In order to facilitate trading of the technology developed in the private sector and to promote the business, the Act of technology transfer and commercialization promotion is prepared. In the law, the article 14 says that who have expertise on commercialization of the technology transfer can be registered as a technology trader to the Minister of Knowledge Economy. For the purpose of finding improvements of the technology trader's registration system, comparison method was studied. Technology trader compare with licensed real estate agent which is similar with it in terms of trade. There are several results from this study by followings. The unique tasks of technology traders should be specified for increasing authority of technology transfer expert. Manual criteria of post management should be prepared through registration certificate management agency which operated by charging. In addition, The announcement document should be prepared carefully for necessity of announcement and registration criteria of technology trading business. These improvements are enable to motivate trading market and impact to expand the base of technology marketing and technology transfer-commercialization.

This paper examines the seller's obligation to deliver documents conforming to the terms of the sales contract as set forth in articles 30 and 34 of the CISG. Article 30 obliges the seller to band over documents relating to the goods. This obligation to band over documents is further elaborated in article 34. According to article 34, the documents must be tendered at the time and place, and in the form, required by the contract. If the seller has delivered non-conforming documents before the agreed time, he has the right to remedy the defects if this would not cause the buyer unreasonable inconvenience or expense. However, the buyer can claim any damages suffered despite the seller's remedy. Specific emphasis is placed on the interplay between the CISG and Incoterms. Incoterms contain detailed rules governing the obligations of the seller to provide for documents. Incoterms constitute international trade usage under articles 9(1) and 9(2) CISG and supplement construction of CISG with UCP under L/C transaction. In the event of failure by seller to deliver the necessary documents, the buyer has certain remedies available, such as the right to claim damages, the right to demand specific performance, and the right to repair. Furthermore, the failure to deliver the required documents under contract constitute a fundamental breach of the underlying sales contract as defined by article 25 of the CISG by the seller, and thereby enable the buyer to avoid the contract entirely article 49. However, it is stressed that since one of the main principles of the CISG is the preservation of the contract, the avoidance of the contract should remain a remedy of last resort.

Real-time multicasting is a packet transmission scheme ensuring that multiple destinations receive a packet within the desired time line. In wireless sensor networks, a packet can be delivered to a limited distance under a given deadline, since the end-to-end delay tends to be proportional to the end-to-end physical distance. Existing real-time multicasting protocols select the distance between the source and the furthest destination as the distance limitation and construct a multicasting tree guaranteeing delivery paths to each destination within the distance limitation. However, the protocols might lead to real-time delivery failures and energy efficiency degradation due to the fixed distance limitation. In this study, we proposed a real-time multicasting protocol using time deadline. The proposed protocol obtains the maximum transmittable distance with a given time deadline and subsequently constructs a multicasting tree using the maximum transmittable distance. The form of the multicasting tree varies according to the given time deadline to trade off the energy efficiency against the real-time delivery success ratio. The simulation results showed that the proposed scheme is superior to the existing protocols in terms of energy efficiency and real-time delivery success ratio under various time deadlines.

The Seoul Metropolitan Area's economy has undergone structural changes since the 1990s. With recent structural changes in the Korean economy in mind, this paper employs a decomposition analysis of Gross Regional Domestic Product per head and labor productivity to examine how the region's economic performance has changed relative to that of Korea since the 1900s. There are some findings. First, a strong cumulative causation process, derived from industrial linkages and agglomeration effects, has oocurred in the Seoul Metropolitan Area, widening economic disparities between the Seoul Metropolitan Area and the other regions especially since the Korean financial crisis in 1997 mainly due to Gyeonggi province's overwhelming cumulative GRDP growth relative to the national average. Second, the Seoul Metropolitan Area has begun w display good economic performance in terms of labour productivity relative w the national average since the late 1990s, with the region's industrial upgrading being implemented. Finally, manufacturing, financial intermediation and communications have made sensitive contributions to relative Seoul Metropolitan Area's labor productivity growth.

The technical regulation and conformity assessment procedure of our country on ICT equipments is currently required to have more innovation due to the request of main trade countries, the second phase conclusion of MRA, necessity of expansion of conformity assessment service market and demand of manufacturers. The world's leading advanced countries have already proceeded with innovation based on privatization plan. According to the comparative analysis of the level, it turned out that Japan obtained the highest level of privatization while South Korea ranked the lowest level. According to the research result of examination and certification ability of private institutions of our country, it turned out that our country is expected to have possibility of achieving higher level of privatization than that of the present. Moreover, according to the questionnaire survey conducted to the persons concerned regarding privatization direction, they gave positive response to all the indicated survey contents of privatization direction in terms of "delegation of certification services to private sectors (contracting-out)", "transformation of EMC into private voluntary standard" and "changeover of conformity assessment agent". However, from the view of acceptance and conflict model, it is estimated that starting from "delegation of certification services to private sectors (contracting-out)" seems to be the most advisable plan. Also, prior to privatization, it is required to improve relevant systems such as certification examiner system.

Most of routing schemes that protect the source's location from a malicious attacker usually make use of a path of a long length per message for the sake of lengthening the safety period. The biggest problem to such approaches is taking a very long latency in transferring messages to the destination. In this paper we show the problem to find the least-cost single path that is enough to keep the source-location always secure from the attacker, provided that it is used for the delivery of a set of messages given in priori, is NP-complete. Consequently we propose a routing protocol GSLP-w(GPSR-based Source-Location Privacy with crew size co) that is a trade-off between two extreme approaches. The advantage of GSLP-co lies in its enhanced safety period for the source and its lowered delivery latency in messaging. We consider NSP(Normalized Sefety Period) and NDL(Normalized Delivery Latency), measured in terms of the least number of hops to the destination, to achieve tangible interpretation of the results. We ran a simulation to confirm our claim by generating 100 topologies of 50,000 nodes with the average number of neighbors being 8. The results show that GSLP-$\omega$ provides more enhanced NSP compared to other protocols GSLP, an earlier version of GSLP-$\omega$, and PR-SP(Phantom Routing - Single Path), the most notable existing protocol for the source-location privacy, and less NDL than that of GSLP but more than that of PR-SP.

Korean shipping industry is ranked the fifth largest in the world in terms of deadweight tonnage after Greece, Japan, Germany and China with 55 million DWT as of year 2011, and its size of foreign exchange earning marked 30 billion US dollars. In respect of volume of seaborne trade, it has handled 99% of import and export cargoes. Korean shipping fleets have increased from 420 to 979 ships between year 2003 to year 2011. By reviewing through the relating literatures, it has been found that Shipping Funds under Ship Investment Company Act, and Tonnnage Tax System, worked as positive influences to increase the Korean shipping fleets. However, there is scant of research to examine the following two points: 1) weighing the decision making factors of ship investments for Korean shipping companies, and 2) weighing the influential factors of government shipping policies. In this respect, the aim of this study is to evaluate 8 decision making factors of ship investments for Korean shipping companies, and 8 influential factors of government shipping policies. For weighing the factors, the fuzzy methodology was adopted. As the results, for the side of decision making factors of ship investments, 'shipping market conditions and future prospects', 'ship's price and future prospects, and 'securing cargoes and future prospects' are ranked as top 3 factors. For government shipping policies side, 'shipping finance provided by lease companies', 'establishment of Korea Shipping Guarantee Fund', and 'establishment of Korea Shipping Finance Corporation' are verified as the important factors.

Port logistics is essential for Korea's economy which heavily rely on international trade. Vast amounts of capital and time are consumed for the operation and development of ports to improve their competitiveness. Therefore, it is important to forecast cargo volume in order to establish the optimum level of construction and development plan. Itemized forecasting is necessary for appropriate port planning, since disaggregate approach is able to provides more realistic solution than aggregate forecasting. We introduce a new time series model which is Two-way Seasonality Multiplied Regressive Model (TSMR) to forecast oil cargo volume, which accounts for a large portion of total cargo volume in Korea. The TSMR model is designed to take into account the characteristics of oil cargo volume which exhibits trends with short and long-term seasonality. To verify the TSMR model, existing forecasting models are also used for a comparison reason. The results shows that the TSMR excels the existing models in terms of forecasting accuracy whereas the TSMR displays weakness in short-term forecasting. In addition, it was shown that the TSMR can be applied to other cargoes that have trends with short- and long-term seasonality through testing applicability of the TSMR.
