This study investigated Thai consumers' perception and willingness to pay for Korean paprika and tomatoes to establish effective export strategies, To this end, an online survey was conducted on 300 consumers living in Bangkok, Thailand, and the factors affecting the purchase intent and willingness to pay price premium for Korean paprika and tomatoes were analyzed. The results are as follows. First, Thai consumers usually buy fruit and vegetables offline, such as supermarkets and large discount stores, but not a few respondents obtained purchase information online. Second, the price competitiveness of Korean paprika and tomatoes is low to Thai products, and the quality, safety, freshness, and cost-effectiveness are similar or low to other exporting countries. Therefore it is important to improve non-price competitiveness using positive perceptions of Korean products and Korean Wave. Third, the most important reason why Thai consumers not buying Korean paprika and tomatoes is the lack of stores and high prices. Fourth, as a result of analyzing the factors affecting the purchase intent for Korean paprika and tomatoes, the strategy of selling paprika and tomatoes through supermarkets to consumers with high income is effective. Fifth, considering the factors of willingness to pay premium prices for Korean paprika and tomatoes, a high pricing strategy targeted consumers with high income and many family members is appropriate.

Structural vibration induced by earthquake hazards is one of the most significant concerns in structure performance-based design. Structural hazards evoked from seismic events must be properly identified to make buildings resilient enough to withstand extreme earthquake loadings. To investigate the effects of combined earthquake-resistant systems, shear walls and five types of dampers are incorporated in nineteen structural models by altering their arrangements. All the building models were developed as per ACI 318-14 and ASCE 7-16. Seismic fragility curves were developed from the incremental dynamic analyses (IDA) performed by using seven sets of ground motions, and eventually, by following FEMA P695 provisions, the collapse margin ratio (CMR) was computed from the collapse curves. It is evident from the results that the seismic performance of the proposed combined shear wall-damper system is significantly better than the models equipped with shear walls only. The scrutinized dual seismic resisting system is expected to be applied practically to ensure a multi-level shield for tall structures in high seismic risk zones.

기업은 IT 를 일종의 자산으로 판단하여 IT 센터를 직접 구축하고 온프레미스 형태의 시스템을 운영했다. 그러나 경영 환경의 변화가 빨라지면서 IT 부문의 비용 효율성에 대한 압박도 커지고 있다. 클라우드 컴퓨팅을 도입하면 IT 자원을 효율적으로 활용하고 사용한 만큼 비용을 지불할 수 있어 IT 자원의 효율화가 가능하다. 하지만 무작정 클라우드로 옮기는 방식으로 인해 시스템 복잡성이 오히려 증가하고, 관리포인트 증가로 시스템 안전성을 해치는 상황이 벌어지고 있는 것도 현실이다. 신규 서비스 제공 시 기존 시스템 안전성을 해치지 않으면서 IT 자원의 효율적인 활용도 고려하는 방안으로 서비스 단위별 클라우드 컴퓨팅 도입을 검토하였다. 이 방법은 클라우드의 우수한 시스템을 사용하며, 실시간 오케스트레이션이 가능하고, 보안도 우수하다고 볼 수 있다. 기존 인프라를 유지하면서 클라우드 컴퓨팅을 구현한 하이브리드 방식으로 시스템 구축 결과 중단 없는 시스템 운영이 가능하였으며, 보안도 보다 강화된 결과를 얻었다. 향후 시스템 구축 시 온프레미스의 경우 서비스 단위로 클라우드 서버를 병행 운영한다면 운영효율성 뿐 아니라 기능성까지 만족시킬 수 있을 것으로 기대한다.

The purpose of this study was to measure the tourists' preference for alternative restaurants with different combinations of 4 attribute levels: origin description, food type, price and service guarantee. A total of 210 questionnaires were completed from tourists who visited Kwangyang, Suncheon and Yeosu during Jan. 2 - Jan. 15, 2007. Conjoint experiment method was used to develop hypothetical restaurants. Ordinal probit model was used to measure the effects of attribute levels on the tourists' preference. Results of the study demonstrated that the ordinal probit model analysis result for the data indicated excellent model fit. The effects of attribute levels (origin description, traditional food, fusion food, price, service guarantee) on the tourists' preference were statistically significant. As expected, estimates of marginal willingness to pay for origin description(3.063), food type(2.349), and service guarantee(2.356) were statistically significant. Moreover, tourists were more willing to pay for origin description than other attribute levels. Tourists also considered the origin description as the very important attribute. In conclusion, based on conjoint analysis, a model was proposed of marginal willingness to pay of attribute levels. It should be noted that the original model was modified and should, preferably, be validated in future research.

This study aims to propose the implementation of innovative payment models in Korea in order to promote the financial sustainability of the national health insurance system by reviewing the current status of the payment system in Korea and examining other countries' experiences with various innovative payment models. Korea primarily uses a fee-for-service payment system and additionally uses various payment systems such as case payment, per diem, and pay-for-performance. However, each payment system has its limitations. Many OECD (Organization for Economic Cooperation and Development) countries have pointed out the limitations of existing payment systems and have been attempting various innovative payment models (e.g., add-on payment, bundled payment, and population-based payment). Therefore, it is essential for Korea to consider innovative payment models, such as a mixed payment model that takes into account the strengths and weaknesses of each payment system, and to design and pilot these models. This process requires stakeholders to work together to build a social consensus on the implementation of innovative payment systems and to refine legal and systematic aspects, develop an integrated health information system, and establish dedicated organizations and committees. These efforts towards innovative payment models will contribute to developing a sustainable health insurance system that ensures the public's health and well-being in Korea.

The issue submitted to the Court of Justice on the merits of case C---573/13 originated from a claim brought in the context of a dispute between Air Berlin and the German Federal Union of Consumer Organisations and Associations. The challenge concerned the way in which air fares were displayed in Air Berlin's computerised booking system. The system was organised in such a way that, after selecting a date and a departure airport, one would find all possible flight connections in a summary table. However, the final price of the ticket was displayed only for the clicked connection, and not for all connections, thus preventing customers from being able to compare such price with the prices of other connections. The German Federal Union took the view that this practice did not meet the requirements laid down by Article 23 of Regulation (EC) No. 1008/2008, which requires transparency in the prices set for air services. This led the German State to bring an injunctive action to cause Air Berlin to discontinue said practice. The claim was upheld at both the application and appeal stage of the relevant proceedings. Subsequently, Air Berlin submitted the matter to the German Federal High Court, which decided to stay the proceedings and ask for a preliminary ruling from the Court of Justice as to 1. whether Article 23 of Regulation (EC) No. 1008/2008 must be interpreted as meaning that, during the computerised booking process, the final price to be paid must be indicated at all times when prices of air services are shown, including when they are shown for the first time; and 2. whether, during the computerised booking process, the final price must be indicated only for the air service specifically selected by the customer or for each air service shown. In a nutshell, the Court, by the here---discussed judgment determined that Article 23 of Regulation (EC) No. 1008/2008 must be interpreted as meaning that, in the context of a computerised air ticket booking system, the final price to be paid must be indicated not only for the air service specifically selected by the customer, but also for each air service in respect of which the fare is shown. Clearly the above judgment will place air companies under an obligation to update and adjust (when needed) their computerised ticket booking and payment systems, in consideration of the primary need for consumers to be aware at all times of the actual price payable for a ticket and be able to compare the price of the service selected with the prices for other air services in respect of which the fare is shown.
