This study discussed the consumption and purchase behaviors of wine by hotel F&B employees based on cluster analysis. Consumption behavior was separated into two categories: place and frequency of drinking. Purchase behavior was divided into two as well: place and price of purchasing. In general, consumption behavior was more influenced by drinking place rather than price, with a wine bar being the most preferred place to drink. Further, purchase behavior was more dependent on the price than place, specifically mid-range priced wine. When selecting wine, "taste" was the most important quality considered for both consumption and purchase behaviors, followed by "price". In addition, "vintage" and "country/winery" were also considered important for consumption behavior. There was no further significant difference among selection attributes for wine quality in terms of purchase behavior. Overall satisfaction after wine consumption was 3.73. Frequency of drinking had a greater impact on overall satisfaction than drinking place. Overall satisfaction after wine purchasing was 3.72, and satisfaction level was greater when a wine was purchased at a wine bar rather than a general bar. With respect to country of origin, France, USA, Chile and Argentina wines all showed even variation among selection attributes for wine quality. However, Italian wine displayed a below average score under "vintage" and "bottle design", whereas Spanish wine did so under "brand". Lastly, Australian wine displayed the lowest scores for all selection attributes.

There has been an increasing demand on measurement of the vibration levels in commercial truck shipments, where all packaged products are exposed to some levels of random vibration and shock. In this study, bear glass bottles loaded at the front, middle, and rear positions of 11 tonne truck bed was shipped from Kwangju to Waegouan. Vertical direction vibration levels were analysed and matching laboratory random vibration test was performed using power spectral density (PSD) profiles derived from truck transit records. Also, the effects of drop hight on glass bottles were evaluated. As expected, the maximum vibration levels were recorded at the rear of truck bed. No breakage of bottles were observed during truck transit and laboratory random vibration testing set at 0.52 $G_{rms}$. In drop test, glass bottles were not damaged by bottom side impact, while short side drop impact caused about twice higher bottle breakage rate than that of long side drop impact at 30 cm and 40 cm drop hight.

To increase the stevedore efficiency and service level at container terminal, it is essential to reduce working time of container crane which has a bottle neck in the logistic flow of container. The working speed and safety are required to be improved by controlling the movement of the trolley as quick as possible without big overshoot and any residual swing motion of container in the vicinity of target position. This paper presents optimal state feedback control using RCGAs in the case of existing constrained conditions

The development of the communication network and the other network method can generate serious social problems. So, it is highly required to control security of network. These problems related security will be developed and keep up to confront with anti-security field such as hacking, cracking. The way to preserve security from hacker or cracker without developing new cryptographic algorithm is keeping the state of anti-cryptanalysis in a prescribed time by means of extending key-length. In this paper, we proposed M3 algorithm for the reduced processing time in the montgomery multiplication part. Proposed M3 algorithm using the matrix function M(.) and lookup table perform optionally montgomery multiplication with repeated operation. In this result, modified repeated operation part produce 30% processing rate than existed montgomery multiplicator. The proposed montgomery multiplication structured unit array method in carry generated part and variable length multiplication for eliminating bottle neck effect with the RSA cryptosystem. Therefore, this proposed montgomery multiplier enforce the real time processing and prevent outer cracking.

There is a request from the client, we almost apply dynamic memory allocating method using Accept() of looping method; thus, there could be process of connecting synchronously lots of client in most of On-line gaming server engine. However, this kind of method causes on-line gaming server which need to support and process the clients, longer loading and bottle necking. Therefore we propose the object pooling scheme to minimize the memory fragmentation and the load of the initialization to the client using an AcceptEx() and static allocating method for an efficient gaming server of the On-line in this paper. We design and implement the gaming server applying to our proposed scheme. Also, we show efficiency of our proposed scheme by performance analysis in this paper.

This research was focused on observing the effect of Makgeolli's selection attributes on customer satisfaction, recommendation intention, and repurchase intention. The purpose of this study was to examine to present a marketing-related suggestion by finding the components that needs to be discussed in order to satisfy the customer and lead to positive word of mouth and repurchasing in the perspective of a corporation. The evidence to achieve the research purpose can be summarized as below. To begin with, the causes of Makgeolli's selection attributes were classified into 9 types, which are design and ad image, expertise and tradition, drinking experience and in harmony with food, taste and freshness, materials and origin, brand image, flavor and color, alcoholic and nutrition, and finally price and recommendation. And it showed up that the average importance of the taste and freshness is the highest. Moreover, the study on the Makgeolli's state of being potable showed up that the drinking number was no more than once a month, and one drink was almost all less than a bottle. The drinking place was usually tavern, and word of mouth was the most often used information medium that contacted Makgeolli. The potential of the Makgeolli's globalization is 80.6% which added positive and very positive, that enables us to infer that the Makgeolli's global dependency is very high. Third, from the 9 types of classification mentioned before, taste and freshness, and price and recommendation were proved to be influential in satisfaction, and recommendation is affecting the repurchase intention and the recommendation intention.

This study analyzes consumers preferences and price sensitivity when buying domestic wine. Data were collected from the consumers (n=200) living in Daegu, Korea. Statistical analyses evaluated purchase, frequency, perceptual mapping, and price sensitivity measurement (PSMs) using SPSS software. Among three domestic wines, ice wine (Vin Coree) attracted most customer satisfaction. The second most popular wine was a white wine (Vin Coree) and the third was a red wine (Royal Campbell). The colors of the red and white wines were highly valued, and bottle design was reported to be the best feature of ice wine. Red wine needs to increase in price and to improve in quality because the price is lower than the point of marginal cheapness. White wine should be reduced in price because the price is higher than the optimal pricing point. The price of ice wine is equal to the point of marginal expensiveness; Thus, the price of ice wine should be reduced.

One of the major technology issues in the ship production processes is the curved hull forming process that is a bottle neck and performed by experienced workers. In order to automate the curved hull forming process, there are a lot of attempts to develop the automation system by many shipbuilding companies and academic labs. However they have some problems which put the developed system in the difficulties to be used and maintained in the yard. In this paper, the problems are formed and solved by using tailored Systems Engineering Process which consists of four steps, those are requirement definition, system design, implementation of subsystem and components, and system integration and verification. A prototype for the proposed system development methodology is implemented. From the consideration of the prototype implemented, it is verified that this methodology can be an alternative to solve the problems.
