As can be seen by the fact that 96% of foreign visitors to Korea travel by air, governments across Asia are aware of the importance civil aviation has in a country's economical developlment, and are fiercely investing in infrastructure and systems which could help set the ground for a hub strategy, catching the profits generated from air travel. In the case of Incheon Internation Airport (IIA), Chinese passengers have outnumbered Japanese passengers using IIA. Considering the potential growth of the Chinese air transport market, there is the growing need for thorough research regarding Chinese passengers. Surveys for the following study were distributed between September 2015 and October 2015, which includes Chinese holidays. Surveys were distributed to Chinese transfer passengers, with questions related to airport service and facility usage.

In order to more effectively respond to the rapidly changing situations of domestic and foreign interior design industries and to expect their further development, not only academic endeavor but also practical one, that is, the introduction of the new interior-design management is necessary. This research aims to establish a preliminary model of interior design management conducted not by customers but by designers who understand the characteristics and structure of business environment. To achieve this, we will investigate and analyze previously suggested theories on interior design management and case examples. In doing so, we hope that this research will facilitate future researches which in turn may come up with more persuasive models of interior design management.

Purpose: This study has developed the accelerated lifetime test method for smps for outdoor lighting LED through two factors of temperature and humidity. Methods: Acceleration condition was confirmed for each stress and model, and acceleration life test model was estimated according to acceleration condition. Results: As a result of confirming the accelerated life test model, in the case of humidity, acceleration was established only in the foreign products. Therefore, it is confirmed that the acceleration condition is insufficient. However, the estimated parameters for temperature are relatively constant. It is therefore suitable for power supply acceleration tests for outdoor lighting LEDs. Conclusion: The SMPS acceleration test for outdoor lighting LED can improve the availability of the product by developing an accelerated life test method that guarantees the reliability of the product.

According to the generalization of mobile device use in our life, the complexity and diversity of mobile applications are increased, and thus the importance of application test to find faults and errors quickly and easily before release grows. This paper reviews the current automatic testing methodologies for mobile device applications and their element technologies. Also, well-known commercial tools for automatic testing are surveyed and case studies of their recent industry applications in domestic and foreign countries are performed.

Eleven Korean learners of English took part in an experiment where the production and perception of English /r/ and /l/ in four different word positions was investigated. Overall the subjects made more errors on /l/ in both production and identification tests. The frequency of the subjects' errors was also sensitive to word positions in which the two English liquids occur. Especially the subjects made noticeably fewer errors in intervocalic medial position. It is suggested that the Korean subjects' acquisitional pattern in this particular case of foreign phone learning can be explained more by language particular 'interference' effects rather than 'universal' acoustic arguments such as those given in Dissosway et a1. (1982) and Sheldon and Strange (1982). The results of the experiment also support the minority position among second language educators that in some cases of non-native phone acquisition, learners' production abilities can be developed earlier than their perceptual abilities.

Since the introduction of competition in the telecommunication market due to the growth of the interconnection between heterogeneous networks, particularly fixed and mobile networks, the interconnection charge based on traffic-sensitive (TS) and non-traffic-sensitive (NTS) costs has become more important. Although there have been many studies of the public switched telephone network (PSTN), previous studies of TS and NTS costs in mobile networks are very few. In this paper, as a pilot study, we propose three criteria and a procedure for the classification of TS and NTS costs based on mobile systems. The three criteria are the following: function type, investment requirement, and main exhaust driver. Moreover, for a CDMA mobile system, strongly TS, strongly NTS, and mixed components are classified by the proposed criteria and procedure. The proposed criteria, procedure, and classification can provide a systematic and useful guideline to decide the scope of mobile facilities and to determine the terminating cost on mobile networks from fixed networks.

본 연구에서는 전자상거래 관련 정보기술을 분류하고 체계화하는 대안을 제시 하고자 한다. 이것은 전자상거래 구현의 효율성과 효과성을 높일 수 있다는 점에서 의미가 있을 뿐만 아니라, 정보산업 관련 분야의 새로운 상품과 서비스시장의 창줄에도 많은 시사점을 줄 수가 있어 그 의의가 있다고 할 수 가 있다. 이를 위해 기존의 사례를 고찰해 봄으로써 기술체계 분류에 대한 유형을 분석하고 좀 더 융통성 있고 합리적인 전자상거래기술구조에 관한 창조모델 획득 방법의 아이디어를 탐색해 보고자 한다.

Railway System has been developed by applying the advanced technology so that it reduces accident of hardware failure. But human error has been founded as important cause in railway accidents and safety. Medical condition is one of railway accident causes. Failure to recognize potentially incapacitating medical conditions can have serious safety consequences for railroad employees, the railroads and the public[1]. In order to find potential danger, we collect domestic/ foreign case for the medical examination and analyse characteristic/difference. The purpose of this study is to suggest information of employees' medical examination through comparing the current medical standard in railway industries.

This study explores building process of innovative capability through overseas direct investment (ODI) by taking the camera business of Samsung Aerospace Industry (SAI) as a case. SAI with less than 20 years history has pursued an aggressive ODI and developed its own camera models. It acquired Rollei in Germany and Union in Japan in 1995, for acquiring advanced technology. Several factors leading to the success of SAI's innovative cability building were taken into consideration. First, SAI effectively absorbed technological knowledge by exchanging technical personnel with foreign partners. Second, it chose right partners with the complementary knowledge required for advancing its technological capability. Third, it strengthened its competrnce to satisfy the technical standards of the partner dompanies in OEM trade relations. Fourth, it successfully formed a global marketing network in which subsidiary companies plays a central role in each region. Finally, SAI successfully addressed the factors of mutual respect between partners in order to let its partners to be confident in their ventures.

Underwater lighting is installed in water tanks, fountains and pools in waterparks, it has direct contact with water and in case of any electrical failure due to faults from electrical equipment, there is a lot of electrical shock risk. In this paper, we proposed an improvement plan of the standard of judgment of electrical code which is MOCIE (Ministry of Commerce, Industry and Energy) notification by fact finding survey and analysis of the domestic and foreign codes.
