The purpose of this study is to investigate the level of payment of accommodation charge to hotel customers and to analyze the differences in hotel choice factors according to the level of payment(low, medium and high prices) to present marketing measures for attracting customers by hotel price range. To achieve the purpose of research, a survey was conducted on hotel customers from February 1, 2020 to April 30, 2020. A total of 350 questionnaires were distributed, eliminating 45 inappropriate copies for analysis, and finally utilizing 305 questionnaires for analysis. According to the analysis, among the basic factors, the biggest difference between groups was hotel size, breakfast menu, restaurants, and auxiliary facilities. It was analyzed that there are differences between groups in the amenity section in the room factor and outside tourism programs in the incidental factor. The main factors were analyzed as the most important factor, although there were no differences between groups. Based on this, the marketing plan is proposed as follows. Low-cost hotels are targeted at women in their 20s with high school diplomas, and it is recommended to have low-cost price policies and promotions. Mid-priced hotels are targeted at men in their 40s with college degrees, and they should strive to operate shuttle buses, promote room prices, and educate employees. In the case of high-priced hotels, it was analyzed that overall service reinforcement, employee education, and viral marketing are important, targeting high school graduates in their 20s.

As random access memory chip gets cheaper, it becomes affordable to realize main memory-based database systems. Consequently, reducing cache misses emerges as the most important issue in current main memory databases, in which CPU speeds have been increasing at 60% per year, compared to the memory speeds at 10% per you. In this paper, we design and implement a main-memory database system for real-time mobile GIS. Our system is composed of 5 modules： the interface manager provides the interface for PDA users； the memory data manager controls spatial and non-spatial data in main-memory using virtual memory techniques； the query manager processes spatial and non-spatial query : the index manager manages the MR-tree index for spatial data and the T-tree index for non-spatial index : the GIS server interface provides the interface with disk-based GIS. The MR-tree proposed propagates node splits upward only if one of the internal nodes on the insertion path has empty space. Thus, the internal nodes of the MR-tree are almost 100% full. Our experimental study shows that the two-dimensional MR-tree performs search up to 2.4 times faster than the ordinary R-tree. To use virtual memory techniques, the memory data manager uses page tables for spatial data, non- spatial data, T-tree and MR-tree. And, it uses indirect addressing techniques for fast reloading from disk.

Cross-border e-commerce has emerged as a crucial force in stabilizing China's foreign trade, driving the transformation and upgrade of China's foreign trade, and contributing to global economic development and stability. As a result, promoting the high-quality development of cross-border e-commerce has become a common challenge within the Chinese industry. However, with the rapid growth of cross-border e-commerce, it faces new phenomena and challenges, such as a mix of quality, fierce competition, and price competition. Brands serve as distinguishing markers for identifying entities, and brand building is a prudent choice for achieving high-quality development in cross-border e-commerce. This article utilizes brand theory, employing a combined qualitative and quantitative approach, with a specific focus on key elements within the operations of cross-border e-commerce enterprises. Through an analysis of the key elements influencing the formation and development of brands within the internal operations of Chinese cross-border e-commerce enterprises, it investigates their internal formation mechanisms and assesses the significance of these critical factors in influencing brand formation. The research process is based on data from overseas consumers, conducting empirical analysis, ultimately providing certain guidance for brand development in cross-border e-commerce enterprises.

수도권의 도시화 과정은 서울로의 교통 접근성의 변화에 따라 급속하게 확산되었고, 현재도 진행 중이다. 도시화 과정 속에 인구 교외화, 주택 수의 증가, 도심용지 토지이용 증대, 토지가격의 증가 등의 다양한 공간적 변화가 이루어지고 있다. 이러한 급속한 도시화의 과정 속에 국토의 난개발이 이루어졌고 자연생태 파괴, 주택부족 및 교통 문제, 토지 투기 등의 사회적 문제를 야기했다. 본 연구에서는 도시화 현황을 살펴보고 교통접근성의 변화에 따른 주변 토지이용 변화의 상관성을 분석하였다 상관성 분석 결과를 토대로 멀티 에이전트 시스템(MAS)을 이용하여 교통접근성과 토지이용 에이전트 간 상호작용의 관점에서 시뮬레이션 하였다. 그래서 교통접근성의 변화로 인한 주변 토지 이용 변화를 공간적으로 예측하려고 한다. 도시화 현황을 살펴보기 위해서 지적도 자료를 이용하여 미시적인 경관 분석을 실시한 후 교통접근성의 변화에 따른 주변 토지이용 변화의 상관성을 분석하기 위해 교통자료와 토지이용 자료를 GIS분석 및 통계 분석하였다. 그리고 상관성 분석 결과를 멀티 에이전트 시스템 전용 플랫폼에 적용하여 시뮬레이션 분석을 하였다.

This paper presents the economic impact of consumer participation in Real-Time Pricing (RTP). A computer model was developed to analyze the impact of real-time pricing on the average price, electricity sales, and the social welfare. Four revenue reconciliation alternative were introduced to illustrate the effect of RTP. Finally a case study was done to analyze the consequent impact of the dynamic load profile on the long-term fuel mix, and the results were compared with those of $5^{th}$ national power development plan.

주요 방산물자의 경우 최저가 입찰 방식의 채택은 방산업체들 간 물량부족에 따른 과다 수주 경쟁으로 인해 터무니없는 낮은 가격으로 업체가 결정되는 경우가 발생되고 있다. 이러한 제도 운영은 방산 물자의 기술 개발 촉진에 장애요인으로 작용할 뿐만 아니라 방위력 증강은 물론 방위산업 육성에도 많은 지장을 초래할 우려가 있다. 본 논문에서는 실천 가능한 방위산업 입찰제도를 도출하고 입찰제도를 개선하기 위해서, 현재 방산청에서 실시하고 있는 최저 입찰제도의 문제점을 알아보고, 미국, 유럽과 일본의 정부조달제도와 방위산업에서의 입찰방식을 살펴본다. 그리고 협상에 의한 계약 체결시 적용하는 회계예규의 평가산식 불합리성 및 문제점을 고찰하고, 국내 방산업체가 느끼는 입찰제도의 문제점을 설문을 통해 파악/분석함으로 방위사업청 제안서 평가 지침에 대한 적절한 방식을 제안하고자 한다.

The Real-Time-Pricing (RTP) brings greatest values in terms of economic incentives and efficiency among the dynamic pricing schemes. The electric power industry in Korea is mainly operated by publicly owned utilities and strongly regulated by the government; therefore, revenue reconciliation of RTP is inevitably required to prevent revenue deficits. In this paper, a revenue reconciliation of real-time pricing considering imperfect information on customer response is proposed to prevent revenue deficit and distortion of the spot price. A case study is present to verify the applicability of the proposed method.

This study investigated the effects of brand awareness and perceived price fairness on the purchase intention of masstige brands and the moderating effect of country of advertising (Korea or China) for the Chinese tourists visiting Korea. Along with the luxury image and the reasonable price range of masstige brands, the effect of Korean models matching with the country of masstige brand and Chinese models for Chinese visitors was examined based on the construal level theory. To test the hypotheses, a 2 (brand awareness H/L)×2 (perceived price fairness)×2 (country of model) factorial design was employed. As a result, brand awareness and price fairness perception were found to have positive effects on the purchase intention of masstige brands, and the moderating effect of the country of advertising models was also significant. With Korean models, the effects of brand awareness and price fairness perception on the purchase intention of masstige brands were higher than with Chinese models. This study sheds light on the fact that for Chinese tourists, Korean advertising models are more effective even with the specific signal like price when they perceive psychological distance.

가상현실과 증강현실의 대중화로 사람의 동작을 실시간 3D 애니메이션으로 구현하는 연구가 활발히 진행 중이다. 특히 Microsoft에서 키넥트 (Kinect)를 개발함에 따라 저렴한 가격에 부가적인 장치 필요 없이 간단한 조작만으로도 3D 모션 정보 취득이 가능해졌다. 하지만 키넥트 카메라는 마커 기반 모션 캡쳐 시스템에 비해 관절 정보의 추정 성능이 뒤떨어져 낮은 정확도를 보이는 단점을 지니고 있다. 이에 본 논문에서는 키넥트 카메라를 이용해 사람의 관절 정보를 취득하고 이것에 관절 가동 범위 (Range of Motion, ROM)를 적용하여 비정상적인 동작을 보정하는 시스템을 제안한다. ROM을 구하는 방법으로는 수행자가 모든 관절에 대해 회전 운동을 수행한 뒤 관절들의 회전 운동 정보를 취득, 분석하여 정상적인 ROM을 설정하고 실험으로부터 사람의 동작이 개선되는 것을 확인하였다.
