As China continues to evolve as a major economic power and the Free Trade Agreement (FTA) between the Republic of Korea and China was ratified on June 1, 2015, market volume between the two countries is expected to grow more rapidly. This study aims on improving the efficiency of car-ferry lines. We conducted two surveys- for shippers and forwarders of car-ferry companies, and container liners. The study analyzes the decision factors for delivery companies and their importance for shippers and forwarders of car-ferry companies and container liners. Based on analysis of prior studies on the competition for car-ferry companies and liners, three primary variables are selected-promptness, economics, and safety. The promptness variable consists of shipping time, loading/unloading time, and customs clearing time. The economic variable consists of marine transportation cost from a domestic harbor to China, loading/unloading cost in the harbor, and overland transport cost from the harbor to shippers inland. Finally, the safety variable consists of cargo damage rates, safety facilities, such as lashing and shoring, and punctuality of transportation time. The survey and AHP results show that the promptness, safety, and economics factors are 0.549, 0.309, and 0.142 in the shipper groups of car-ferry companies' category, respectively. It indicates that there is considerable difference in the importance of each factor. In contrast, the factors are 0.350, 0.348, and 0.302 in the forwarders category, which suggests that there is little difference in each factor's importance. As for shippers and forwarders of liners, the importance of each factor is found to be in the following order: economics, safety, and promptness.

The purpose of this study was to present the effective activation of apparel CAD system and for this, the investigation of actual condition of CAD using companies and comparative inspection with the advanced study were carefully considered. The results were as follows : 1. The investigation result of the system using enterprises is that the direct effect from the operation of the CAD system after its introduction was the promptness, ad the indirect effect of it was the growth of operation level and operating reliance. 2. The problem originated from the system was the uncertainty of employer effectiveness and the financing source for it when introduced, and the lack of consciousness of it when operated. 3. The using level in pattern manufacturing function was lower than that in grading and marking. Therefore, as the full automation in CAD system is a part of CIM construction and the direction to which apparel companies should go, a firmly connected system between management & the persons in charge in apparel companies, facility supplying companies, universities & other educational institutes, and the Government should be duly constructed first of all n order to achieve this aim.

In the era of global competition, international competitiveness depends greatly on the prompt provision of overseas information. In the field of Science and Technology, it is very important to catch the research or technical trends of advanced countries in time. In this paper, we explain the process of collecting, evaluating, and distributing KISTI's overseas S&T trend information service. We also explain a quality management system which evaluates the quality of the information without loosing promptness.

Among the many parameters describing water quality, total nitrogen content(TN) is regarded as important one in relation to water quality management of the waterbodies for its role in eutrophication process. This study evaluated for accuracy, convenience and promptness of nitrogen analysis methods : (1)UV spectrophotometric method, (2)summation method, (3)cadmium reduction method. And, the detection limit of each method was calculated using EPA method. The UV spectrophotometric method after oxidation appears to be more convenient and accurate in determination of the TN contents than the summation method and cadmium reduction method. The summation method is necessary to separate determinations of the organic nitrogen, ammonia, nitrite, and nitrate. And, because summation method has many other methods for each contents, it can be detected for wide range of concentration.

Convenience and promptness of the internet have been not only making the electronic commerce grow rapidly in case of website, analyzing a navigation pattern of the users has been also making personalization and customization techniques develop rapidly for providing service accordant to individual interestingness. Web personalization and customization skill has been utilizing various methods, such as web log mining to use web log data and web mining to use the transaction of users etc, especially e-CRM analyzing a navigation pattern of the users. In this paper, We measure exact duration time of the users in web page and web site, compute weight about duration time each page, and propose a way to comprehend e-loyalty through the computed weight.

Purpose With the increasing number of foreign travelers visiting Korea, it is a heavy question to evaluate service quality of typical domestic hotel companies. Our research aims to evaluate service quality of domestic hotels in Korea from the perspective of foreign travelers in order to provide the quality improvements that call attention for the hotel management. Design/Methodology/Approach In this paper, topics of sentiment followed Lodging Quality Index(LQI) dimensions classifying lodging service quality appropriately. Also, we employed word2vec algorithm which calculates similarity and affinity among the vocabularies accurately. To calculate sentiment of each dimension, we adopted scores from SentiWordNet. Findings From the result, we found the number of foreign travelers particularly satisfied with cleanliness, politeness, and problem solving skills. In contrast, it has also been found out that both promptness of services and efficiency of communication do not fulfill the requirements of travelers.

Recently people have come to demand more pleasant environments as the quality and right of life have been improved. Along with industrial development, the tendency is causing a growing number of disputes concerning environmental damages. Of many kinds of environmental damages, noise and vibration pollution rising at construction fields are particularly the most common subjects of public grievance. Thus the government launched the Environmental Dispute Mediation Committee in 1991, purposing to utilize fully the promptness and expertise of administrative institutes and to resolve environmental damage disputes promptly and fairly by interfering in them actively. With the prompt and fair dispute mediations of the committee, people came to be able to get fair and prompt remedies for damages in their health and fortune by environmental pollution. Therefore, by analyzing dispute mediation cases on construction noise and vibration damages, we will suggest basic material on which efficient actions can be taken for public grievances happening in the future.

Diverse researches using vegetation index have been carried out to monitor spring droughts that have frequently occurred since 2000. The strength of the drought monitoring using vegetation index lies in that it can reflect characteristics of satellite images: large area coverage, cyclicity, and promptness. However, vegetation index involve uncertainly caused by diverse factors that affect vegetation stress. In this study, multi-temporal vegetation index is compared with the most representative meteorological drought indices like PSDI, SPI. Based on the results from analyses, usability of vegetation index as a tool of drought analysis is proposed.

Today, use of high resolution satellite image with at least 1m resolution is expanding into many more areas including forest, river way, city, seashore and so forth for disaster prevention. Interest in this medium is increasing among the general public due to the roll-out to the private sector as Google earth, Virtual Earth and so forth. However, pre-processing process that revises the geometrical distortion that result at the time of photographing is required in order to use high resolution satellite image. The purpose of this research is to search the most accurate GCP(Ground Control Point) information acquisition method that is used for the revision of high resolution satellite image's geometrical distortion through automated processing. Through this, it is possible to contribute to increasing the level of accuracy at the time of high resolution satellite image revision and to secure promptness.
