Purpose - This study aims to investigate the process of political changes in Japan, which has introduced regulatory policies for large-scale retail stores since the 1930s, as well as the examples, and suggests improvement schemes for our policies in Korea, which imposes restrictions on business hours and forced holidays in accordance with the current Distribution Industry Development Act. Research design, data, and methodology - After examining the political change processes related to large-scale retail stores in japan, this study analyzes individually regulated cases based on the ordinances enacted by each local government. Through case analysis in Japan, this study makes political suggestions that may be helpful for our country substantially. Results - Since there is an obvious possibility that our economic restrictions on business hours and mandatory holidays do not coincide with WTO GATS, it is necessary for large-scale distributors to introduce new social and environmental regulations similar to Japan, rather than imposing controls to restrict free competition and also introduce a policy to induce cooperation with small businesses for the advancement of the distribution industry. Thus, it is desirable to take measures on noise, waste, traffic, and parking for the preservation of the living environment in the surroundings when building new large-scale retail stores. It is also important to establish measures to improve the welfare of neighborhood residents and consumers, create a pleasant urban environment, and make it mandatory to make presentations at public hearings among residents. Furthermore, it should be mandatory to establish regional contribution plans when a retail store is established, and take measures to solve various civil complaints or problems that may occur after entering the market. Moreover, it is desirable for large-scale retail stores that entered the market to induce cooperation in performing various activities in the area with a strong sense that they are all members of the local economy. Conclusions - If introducing social regulations like in Japan, there is probably an advantage that the conflicts seen when large-scale retail stores enter the market are absorbed by adjusting the persons concerned within the established institution in order to establish a field to solve such conflicts systematically. In contrast, there are still concerns regarding chaotic operation without any active attempts to have a conversation with large-scale retail stores and local small merchants due to a sharp conflict among the persons concerned, and if it is a briefing session without any decision of the restrictions on their opening itself, there may be doubts with regard to their effectiveness. Moreover, if the de facto opening is restricted by the introduction of such a briefing session procedure, the choice of whether to protect the existing rights of large-scale retail stores might become problematic. However, such problems could be minimized in a way by forming a separate consultative group for all persons concerned including residents, local governments, professionals, civic organizations, small merchants, and massive retail store-related persons.

Nowadays, we have many embedded systems which store and process multimedia data. For multimedia systems using hard disks as storage media such as DVR, existing file systems are not the right choice to store multimedia data in terms of cost. performance and reliability. In this study we designed a reliable file system with very high performance for embedded multimedia applications. The proposed file system runs with quite simple disk layout to reduce time to initialize and to recover after power failures, uses a large data block to speed up the sequential accesses, incorporates a time-based indexing scheme to improve the time-based random accesses and boosts reliability by backing up the important meta data on a small NVRAM. We implemented the file system on a Linux-based DVR and verified the performance by comparing with existing file systems.

최근 휴대용 기기들이 대중화되어 한 사람이 하나 이상의 휴대용 기기를 소지하고 있고 스마트폰 활용도 또한 늘어나는 추세이다. 스마트폰이 많이 보급됨에 따라 폭발적으로 스마트폰의 애플리케이션 활용이 늘어나고 있다. 현재의 애플리케이션 스토어는 플랫폼별로 애플리케이션을 개발해줘야 하는 종속적인 면이 있다. 앱스토어는 크게 애플의 앱스토어와 구글의 안드로이드 마켓으로 양분되어 있고 각 플랫폼에 맞춰 애플리케이션이 개발되어야 한다. 각각의 플랫폼에 맞춰서 애플리케이션을 개발하면 개발 비용은 2배에 근접하고 다른 소규모 플랫폼(Ex 바다)들은 애플리케이션 개발자들을 모아야만 자신들의 플랫폼에 맞는 애플리케이션이 나오는 단점이 있다. 이러한 플랫폼에 맞춰서 개발된 네이티브 애플리케이션의 범용성에 대한 해결책과 모바일에서의 다양한 요구사항을 수용하기 위해 웹 애플리케이션이 각광받고 있다. 웹 애플리케이션은 플랫폼에 종속되지 않고 어느 휴대용 기기에서도 동작하기 때문에 각 플랫폼별로 개발하지 않아도 된다는 장점이 있다. 따라서 웹 애플리케이션 스토어끼리의 연동 프로토콜을 통해 애플리케이션을 연동하여 어느 웹 애플리케이션 스토어에서도 볼 수 있고 특정 플랫폼에 구애받지 않는 거대한 시장이 생겨날 수 있다. 하지만 아직 웹 애플리케이션 스토어라는 표준이 없고 존재하는 웹 애플리케이션 스토어가 없다. 이를 위해 본 논문에서는 연동에 관한 프로토콜을 제안하고 구현을 통해 기존의 애플리케이션 스토어의 단점을 보완할 수 있는 방법을 제시한다.

Activation of conventional market in small town is important in the reinvigoration of local economy as an economical center. The revitalization of local economy is closely related to the fosterage of conventional market. So the local government is trying to activate the market. However, the projects for the activation of conventional market are mostly centered on the modernization of facilities which is carried out at urban districts. Those facilities-centered plans, being carried out at urban district, lack the consideration of the peculiarities of rural districts and the regional conditions of the conventional market in small towns. And some projects for the modernization of facilities produce negative results. Especially the conventional market in small town shows a spatial structure of a five-day market and a market place and it was influenced by the spatial relationship between the permanent market and periodic market. So analyses on the spatial lay-out and form, store facilities, spatial distribution of types of business, spatial utilization on market place are needed to improve the physical environment of the conventional market. In this context, the study analyzed systematically the space of an old and lagged Hongseong conventional market located in central district of a small town. And It is expected that the results use as a basic data to establish effective space improvement plan for conventional market in small town.

Ninety tow percent of over 1,800 gate controlled dams in Korea are classified as small dams. The primary purpose of these small dams is to supply irrigation water. Therefore, while large dams can store as much as 80 percent of precipitation and thus are efficient to control flood, small dams are often lack of flood control function resulting in increased susceptibility drought and flood events. The purpose of this study is to develope a storage management model for irrigation dams occupying the largest portion of small dams. The proposed Storage Management Model (STMM) can be applied to the Seongju dam for efficient management. Besides, the operation standard is capable of analyzing additional available water, considering water demand and supply conditions of watershed realistically. And the model can improve the flood control capacity and water utilization efficiency by the flexible operation of storage space. Consequently, if the small dams are managed by the proposed Storage management model, it is possible to maximize water resources securance and minimize drought and flood damages.

Recently, small satellite industries are rapidly changing. Demand for high performance small satellites is increasing with the expansion of Earth Observation Satellite market. A next-generation small satellites require a higher resolution image storage capacity than before. However, there is a problem that the HW configuration of the existing small satellite image storage device could not meet these requirements. The conventional data storing system uses SDRAM to store image data taken from satellites. When SDRAM is used in small satellite platform of a next generation, there is a problem that the cost of physical space is eight times higher and satellite price is two times higher than NAND Flash. Using the same satellite hardware configuration for next-generation satellites will increase the satellite volume to meet hardware requirements. Additional cost is required for structural design, environmental testing, and satellite launch due to increasing volume. Therefore, in order to construct a low-cost, high-efficiency system. This paper shows a next-generation solid state recorder unit (SSRU) using MRAM and NAND Flash instead of SDRAM. As a result of this research, next generation small satellite retain a storage size and weight and improves the data storage space by 15 times and the storage speed by 4.5 times compare to conventional design. Also reduced energy consumption by 96% compared to SDRAM based storage devices.

The small & micro business has the characteristics of both consumer credit risk and business credit risk. In predicting the bankruptcy for small-micro businesses, the problem is that in most cases, the financial data for evaluating business credit risks of small & micro businesses are not available. To alleviate such problem, we propose a bankruptcy prediction mechanism using the credit card sales information available, because most small businesses are member store of some credit card issuers, which is the main purpose of this study. In order to perform this study, we derive some variables and analyze the relationship between good and bad signs. We employ the new statistical learning technique, support vector machines (SVM) as a classifier. We use grid search technique to find out better parameter for SVM. The experimental result shows that credit card sales information could be a good substitute for the financial data for evaluating business credit risk in predicting the bankruptcy for small-micro businesses. In addition, we also find out that SVM performs best, when compared with other classifiers such as neural networks, CART, C5.0 multivariate discriminant analysis (MDA), and logistic regression.

포화상태에 이른 우리나라 종합슈퍼들의 심각한 경쟁으로 인한 부작용을 해결할 수 있는 단서를 찾기 위해 본 연구는 종합슈퍼들의 다양한 마케팅 커뮤니케이션 요인들이 소비자들의 점포충성도에 미치는 직접적인 영향과, 마케팅 커뮤니케이션 요인들과 소비감정, 점포충성도 각각에 대해 소비가치와 소비감정이 유인가(valence)를 이끌어낼 수 있는지를 확인하고자 하였다. 특히 미래의 소비자인 대학생들의 관점에서 구성한 연구모델을 분석함으로써 장기적인 차원에서 종합슈퍼들이 경쟁력 강화를 위해 얻을 수 있는 단서를 찾고자 하였다. 본 연구의 수행을 위해 먼저 마케팅 커뮤니케이션의 각 요인들로는 선행연구를 근거로 광고, 퍼블리시티, 판매촉진, 구전, 물리적 환경을 채택하였으며, 가치는 쾌락적 가치와 실용적 가치로 나누어 분석하였다. 연구 결과는 다음과 같다. 첫째, 종합슈퍼들의 마케팅 커뮤니케이션 각 요인들이 점포충성도에 미치는 영향을 분석한 결과 광고, 퍼블리시티, 판매촉진, 구전, 물리적 환경의 각 요인들이 모두 통계적으로 유의미한 정(+)의 영향을 미치는 것을 확인하였다. 마케팅 커뮤니케이션 하위 요인들 중 어떤 요인이 점포충성도에 미치는 영향이 더 큰지를 확인한 결과에는 구전요인(β =.53, p<.01)만이 통계적으로 유의미한 결과를 보였다. 이에 대해서는 대학생들은 다른 요인들에 비해 구전 요인을 좀 더 점포를 신뢰하는데 중요한 요인으로 생각한다고 해석하는 것이 바람직할 것이다. 둘째, 종합슈퍼들의 마케팅 커뮤니케이션 각 요인들과 점포충성도의 관계에서 쾌락적 가치와 실용적 가치의 조절효과를 검증한 결과 유일하게 퍼블리시티와 점포충성도간에 실용적 가치만이 통계적으로 유의미한 영향을 미치는 것으로 나타났다. 흥미로운 것은 실용적 가치가 퍼블리시티와 점포충성도 간에 부(-)적인 영향을 미치는 것으로 분석되었는데, 이는 최근까지 이슈화된 종합슈퍼들에 대한 매스미디어의 부정적 기사들에 대해 대학생들이 민감하게 반응한 결과로 해석할 수 있다. 셋째, 마케팅 커뮤니케이션 각 요인들과 소비감정 간에 소비가치의 조절효과를 검증한 결과 쾌락적 가치만이 퍼블리시티와 소비감정에 조절효과를 보이지 않았으며, 모든 요인들이 조절효과가 있음을 확인하였다. 따라서 대학생들이 인지하는 소비가치는 마케팅 커뮤니케이션과 점포충성도 간의 관계보다 소비감정 간에 더 영향을 미치고 있음을 알 수 있었다. 마지막으로, 마케팅 커뮤니케이션의 각 요인들과 점포충성도의 관계에서 소비감정의 매개효과를 검증한 결과 판매촉진을 제외하고 모든 요인들이 완전 매개 또는 부분 매개하는 것으로 나타났다. 이는 소비감정이 점포충성도를 높이는데 중요한 요인임을 시사하고 있으며 종합슈퍼들이 긍정적 소비감정의 증대를 위한 노력을 하여야 함을 의미한다고 판단된다. 말미에는 이 연구결과를 통해 얻을 수 있는 영향을 제시하였으며 향후에는 범위를 넓혀 일반인들을 대상으로 한 연구와 함께 세대 간 차이를 확인할 필요가 있음을 제안하였다.

This study investigates store separation characteristics of an unmanned aerial vehicle having generic stealth configuration over unsteady flow of an internal bay. Free-drop wind tunnel tests are conducted to simulate bomb releases from an internal weapons bay while high-speed camera images are taken. The images are analyzed to examine the effects of flow velocity, angle of attack, flap deflection and the ejector force application on the store separation trajectories. For the free-drop wind tunnel tests, Froude Scaling is applied to match the dynamic similarity for the bomb model, and the ejector force is simulated by using small pneumatic cylinders. The results indicate that the test bomb model safely separates from the internal bay at the given test conditions and configurations. It is also observed that the effects of the flow velocity and ejector force application have greater impacts on the separation trajectories than those of angle of attack and flap deflection.
