The purpose of this study was to extract the evaluation factors and assess the relative importance between the factors. For this purpose, the evaluation factors were extracted through literature review and the process of brainstorming with experts, who are related to port security. The evaluation factors were then classified into four higher factors and twelve sub- factors through the use of the AHP method. A survey on the classified factors was conducted by experts composed of public officials, port authority employees and education institutions officials. We also carried out statistical tests to determine the perception gap of weights between the groups. As a result of a relative importance analysis of strength, the security operating system factor was highest, followed by improvement of hardware facilities and increase of security personnel. There was a difference in perception among the groups in policy support, facility support and personnel resources budget support. The results of the analysis show that the strength operating system through the establishment of an integrated monitoring system is a priority. It is necessary to understand the difference of perception between groups and build a systematic cooperation system. The evaluation factors extracted from this study can be used for the measurement of port security efficiency in further work.

Many companies are executing big data analysis and utilization projects to legitimize the development of new business areas or conversion of management or technical strategies. In Korea and abroad, however, such projects are failing because they are not completed within specified deadlines, which is not unrelated to the current situation in which the knowledge base for big data project risk management from an engineering perspective is grossly lacking. As such, the current study analyzes the risk factors of big data implementation and utilization projects, in addition to finding risk factors that are highly important. To achieve this end, the study extracts project risk factors via literature review, after which they are grouped using affinity methodology and sifted through expert surveys. The deduced risk factors are structuralize using factor analysis to develop a table that categorizes various types of big data project risk factors. The current study is significant that in it provides a basis for developing basic control indicators related to risk identification, risk assessment, and risk analysis. The findings from the study contribute greatly to the success of big data projects, by providing theoretical basis regarding efficient big data project risk management.

In 2017, the government of Duterte, in the second year of the ruling, more strongly promoted peace and order policies and expressed independent diplomacy as the chairman of ASEAN. He continued to fight against drugs and tried to increase his political legitimacy through the punishment for corrupt officials. He also declared martial law in the Mindanao region because of the dissolution of the Maute group, a Muslim terrorist organization, and strengthened counterterrorism cooperation externally. In addition, as to Communist militants, he took the initial reconciliation gesture and promoted peace negotiations, however, concluded the peace tide and started the suppression operation due to a series of bloodshed. He still has a strong drive in peace and order issues, backed up by high support rate, but it is becoming a factor of anxiety as the socioeconomically underprivileged and minority groups are increasingly alienated. As the chairman of ASEAN, Duterte has a certain distance from the United States, which is a firm ally, but has turned to increase familiarity with China and Russia, which can take substantial economic benefits. Through diversifying the external economic support and increase of tax revenue, the priority task was to establish the infrastructure. Although the Philippines, which has a high economic growth rate, has a strong expectation that it can establish a solid infrastructure, tax reforms should be successfully completed in order not to repeat the previous failures, which has traditionally increased foreign debt burden by relying on external resources. It seems that it is necessary to find the meeting point of the foreign policy of Duterte and new Korean government's New Southern Policy, and to find possible economic cooperation policies to improve Philippine infrastructure.

In this study, I examine overall conditions and problems of personal asset management processes by the old age people in Korea from the global perspectives. Major recommended policy implications for those are as follows.. First, the IRR (income replacement ratio) of public pensions in Korea is found to rank nearly the lowest among the OECD member countries. The relatively low fund performance compared to that of developed countries as well as this low IRR can be pointed out as major problems of public pension in Korea. It is recommended to reinforce specialty in fund management as a top priority to solve out these problems related with public pensions in Korea. Second, it is needed to set retirement pensions to be mandatory for almost all the firms in Korea to substitute for the above lower IRR of public pensions and to recover from the highest elderly poverty ratio among the OECD countries. Third, it is required to discuss about the expansion of tax refund policy application in the individual pension sector and many financial investment products under the correction of current budget control to motivate voluntary subscription for individual pension planning and to stabilize elderly lives of ordinary people in Korea. Fourth, it is required to induce market mechanism in controling price and longevity risk of reverse mortgages for the long-run sustainability.

Tug services are essential services to ensure port safety. However, due to the relatively low barrier to entry into the tug service market, the number of service companies has increased, which has led to growing concerns about excessive competition among companies and poor service quality. To solve these problems, it is necessary to prepare a service quality evaluation system, but full-fledged implementation remains far away. The purpose of this study is to develop a tug service quality evaluation model that can be practically applied. To this end, an evaluation model consisting of two major categories, eight middle categories, and 25 detailed evaluation indicators was developed through a literature review, case studies, and expert interviews. AHP analysis is also conducted to derive the relative importance of the evaluation items. As a result of the analysis, it was found that the weight of user satisfaction was higher than that of management evaluation. In addition, the weights for each detailed indicator of management evaluation were in descending order of facility management, company management, and financial soundness, and it was analyzed that the management of facilities directly used for services was important. User satisfaction is in descending order of safety, punctuality, service satisfaction convenience, and transparency. These results show that securing safety is a top priority, and that the inherent quality of services such as safety and punctuality is more urgent than those of the convenience and transparency of the process in terms of providing preliminary services.

Objectives: To develop the smart sensor to protect worker's health from chemical exposure by adopting ICT (Information and Communications Technology) technologies. Methods: To develope real-time chemical exposure monitoring system, IoT (Internet of Things) sensor technology and regulations were reviewed. We developed and produced smart sensor. A smart sensor is a system consisting of a sensor unit, a communication unit, and a platform. To verify the performance of smart sensors, each sensor has been certified by the Korea Laboratory Accreditation Scheme (KOLAS). Results: Chemicals (TVOC; Total Volatile Organic Compounds, Cl₂: Chlorine, HF: Hydrogen fluoride and HCN: Hydrogen cyanide) were selected according to a priority logic (KOSHA Alert, acute poisoning statistics, literature review). Notifications were set according to OEL (occupational exposure limit). Sensors were selected based on OEL and the capabilities of the sensors. Communication is designed to use LTE (Long Term Evolution) and Wi-Fi at the same time for convenience. Electronic platform were applied to build this monitoring system. Conclusions: Real-time monitoring system for OEL of hazardous chemicals in workplace was developed. Smart sensor can detect chemicals to complement monitoring of traditional workplace environmental monitoring such as short term and peak exposure. Further research is needed to expand the scope of application, improve reliability, and systematically application.

This study examines Romalpa clause as an extended or enlarged retention of title clause under SGA. Under a simple retention of title clause, the seller retains title to goods supplied until the goods have been paid. A simple retention of title gives the seller super-priority interest in other creditors of the buyer without registering a charge. Aluminium Industrie Vaassen BV v. Romalpa Aluminium Ltd introduced the concept of 'extended reservation of title(so called 'Romalpa clause') in English law. It is because the Court of Appeal held that under an extended reservation about title clause the seller can trace his title into money which constitutes the proceed of sale by the buyer of goods supplied by the seller. However, since Romalpa case, the courts are reluctant to uphold the seller's extended title. Under Romalpa clause, the seller attempts to extend his protection by laying claims to new products manufactured from his goods or to proceeds of sale by the buyer. Where the seller's goods are lawfully used by the buyer to create new goods, the property in the new goods will generally vest in the buyer. It is because there has been discomfort if the seller gains the windfall profit of the new goods. Moreover, regarding tracing proceeds of sale by the buyer, the courts held that the seller must establish fiduciary relationship with the buyer. If the fiduciary requirement cannot be established, the extended retention of title clause is seen as a charge over the proceeds, and void if not registered. For these reasons, it is difficult that the claims based on the extended retention of title clause would be upheld.

The internationalization of venture firms is of importance resulting from the increased opportunities as well as the entry barriers faced in this process. This study is to investigate barrier factors affecting Korean venture firms' internationalization. Among these factors, we measured relative weights using Analytic Hierarchy Process (AHP). Literatures regarding global firm's internationalization was reviewed, and barriers were classified environment, corporate and CEO barriers. Multiple variables were used in order to measure their relative significance. We surveyed executives of venture firms comprising two groups: first, 15 global venture firms, and secondly, gradually internationalizing firms. The two groups show contradictory results as environment barriers are the primary for born-global ventures and corporate barriers are the primary for gradually internationalizing ventures. Concerning corporate barriers, the lack of marketing capability is the highest barrier for both groups. The CEO barrier is the lowest for both groups. Regarding corporate barriers, gradually internationalizing ventures considers the risk of business as highest, whereas born-global ventures features the lack of R&D capacity as highest Results of this paper imply that firms should consider priority and sequential approaches in facing environment, corporate and CEO barriers.

Since the global financial crisis, major countries have been executing policies related to two top-priority goals to create more jobs: revitalization of entrepreneur activity and the cultivation of small and medium-sized companies. In South Korea, the interest of policy makers is increasingly focusing on the role of SMEs that have a technological competitive edge in the realization of a "job-centered creative economy." Due to the nature of the field, the health and medical industry requires a particularly long time until the achievement of industrialization, Also, because of the complex distribution structure, it is essential for related government ministries and institutions to jointly devise strategies. A lack of policy supports for the industry has thus far resulted in its development being relegated for the most part of small and medium-sized companies, which consequently means low global competitiveness. Now is the time for the South Korean government to provide the revolutionary supported options and strategies. This study aims to propose a general policy direction and policy areas for the cultivation of Korea's small and medium-sized companies in the healthcare industry into global small giant companies through an exploration of the German case. It is crucial to first cultivate the international competitiveness of Korean small and medium-sized companies (as in the case of Germany) so that they can grow into global small giant companies. Another important task is the creation of an environment that expedites the qualitative growth of promising SMEs as well as technological development. After securing competitiveness in terms of both product quality and technology in the global health market, substantive policy supports will be necessary to cultivate global small giant companies that are export-based (e.g. job creation effect, sales value added).

Despite its rising labor costs these days, China still serves the role as 'World's Factory' thanks to a great deal of foreign direct investment, still remaining one of the world's highest, and the global companies, which have been willingly establishing foreign subsidiaries in China. While enjoying the benefits from the Chinese market, these global companies can now take advantages of another market; the one of Korea. If a product produced by a certain global company is actually manufactured in the local factory in China and the product meets specifications of Rules of Origin, the product shall receive preferential treatment under China-Korea FTA. In the perspective of global market, therefore, it is found that China-Korea FTA may have negative effects on chemical industry in Korea, which is considered one of the representatives of China-Korea FTA. This study examines such risks by network analysis, with several cases of 'Beauty or Make-up Preparations (HS Code 3304).' Analysis shows that Korea is classified as the marginal country group but not main country group when it comes to beauty products family. So this can be a great chance to the global cosmetic companies with local factories in China in the sense that they can increase their sales towards the market of Korea based on the China-Korea FTA. Under these concerns, this study suggests two policy alternatives for the chemical industry in Korea to deal with current challenges rising from China-Korea FTA. The suggested alternatives are: to actively attract the global chemical corporations which are yet to directly enter the Chinese market; and to invest on chemical products with high potential of growth as a priority.
