Direct analysis in real time mass spectrometry (DART-MS) is one of the variants of ambient mass spectrometry. The ionization process of DART-MS is in open environment and only takes few seconds, so it is suitable for fast analysis. Actually, since its introduction in 2005, more and more attentions have been drawn to its various applications due to its excellent properties, e.g., fast analysis, and no or less sample preparation, high salt tolerance and so on. This review summarized the promising features of DART-MS, including its ionization mechanism, equipment modification, wide applications, coupling techniques and extraction strategies before analysis.

This study was conducted to identify the relationship among various service quality clues, brand trust, brand distinctiveness and revisit intention focusing on fast-food restaurant consumers. Using online questionnaires tool in South Korea, a total of 450 questionnaires were distributed and 390 participants were used for further statistical analysis through SPSS 21.0 and AMOS 21.0 for Windows. Four service quality factors (menu, interior, exterior, staff) were extracted from twelve questions. According to the result of this study, several service quality factors of fast-food restaurants' have positive effects on brand trust and distinctiveness. Specifically, staff and menu and exterior were significant predictors of brand trust, and staff and menu of fast-food were critical antecedents of brand distinctiveness. In addition, the brand trust has positive influence on brand distinctiveness as well as revisit intention. Although there are many studies which proved the relationships among various selection attributes and other outcome variables such as brand loyalty or image, little research explained the relationships among service quality factors of fast-food restaurants, brand trust, brand distinctiveness, and revisit intention. Therefore, present study will contribute to provide significant results and some practical implications in both the fast-food restaurant industry and academic research.

This research evaluates the availability of consumers moving to integrated multi channels by a target analysis on the integrated online channel and verifies the possibility of a synergy effect created by the expansion of an integrated online channel. The objectives are to define the scope of benefits desired in fast fashion and online shopping, compare the desired benefits of fast fashion consumers, online shopping consumers and fast fashion, and online shopping consumers, investigate the acceptance intention of the integrated online channel of consumers, and verity its relationship with the desired benefits. As a result, all consumers indicate the desire to pursue social recognition, pleasure, individuality, economic and convenience orientation, and fashion-innovativeness through shopping activities. In addition, there were differences in the mean of social recognition benefit individuality benefit, economical and convenience orientation benefit, and fashion-innovativeness benefit. Lastly, the acceptance intention of the integrated online channel was significant in all groups and the desired benefits that affect the acceptance intention of the integrated online channel were social recognition for fast fashion consumers along with pleasure and individuality for fast fashion and online shopping consumers.

This study was to investigate utilization state of various fast-foods among Korean youth in big cities in order to provide basic knowledge for nutrition education of Korean youth. Total 29 questions were asked to 1680 middle, high school and college students in Seoul. Pusan and Taejon. General information of the subjects were analyzed according to variables such as utilization state of fast foods(hamburger, pizza, chicken, noodles & mandoo, ice cream), preference, concenpts regarding price, fullness, choice factors and influences on food habits. All statistical data analysis were conducted using the SPSS/PC+. The results obtained are summarized as follows: 1) Fast-food eaten most frequently was noodles & mandoo where the least frequently eaten was pizza. 2) The area used fast-feeds the least frequently was in Pusan where hamburger was used by 51.1% of the subjects, pizza by 26.5% 64.1%, 38.9% of the subjects in Seoul and 64.7%, 31.3% in Taejon ate hamburger & pizza, respectively. 3) 38.5%, 34.2%, 32.8% and 17.5% of chicken, pizza, noodles & mondoo and hamburger eaters commented on saltiness. Also 82.2% of ice cream eaters suggested ice creams taste too sweet. 4) 94.2%, 72%, 69.5%, 38.5% and 23.8% of pizza, chicken, hamburger, ice cream, noodles & mandoo eaters suggested the price of these fast-foods too expensive. 5) 39.6% of the subjects wished to developed Korean traditional food items into fast-food styles.

The fast filling process of high-pressure hydrogen has an important impact on the filling efficiency and safety. In this paper, a specific study is carried out on the thermophysical phenomena during the fast filling process. Starting from the gas state equation of hydrogen, the change law of the hydrogen storage temperature is obtained, and then the temperature rise prediction is constructed. The model can clarify the relationship between the filling parameters and the temperature rise during the fast filling process, thereby revealing the flow and heat transfer laws of the fast charging process. To improve the theoretical research basis for the evaluation of vehicle-mounted hydrogen fast charging capacity, temperature prediction and optimization of hydrogenation methods.

This study aims at providing managerial insight into researchers and marketers who are intending to maintain and develop a loyal group and long-term relationships in fast food restaurants. The summary of results is as follows : There was a wide difference in evaluation of perceived value, trust and customer loyalty according to sex, age, occupation and customer's visit behavior. Customers considered the convenient and quick service as the most important selective factor. And also, the important attribute of fast food restaurants was taste of food, followed by price, cleanliness, kindly service, quick service. We are able to classify the four customer groups according to analysis results. If we lay great emphasis on the above mentioned selective factors and also develop needs in each customer group, it does much for delivering profits of fast food restaurants.

이 연구에서는 부유식 풍력발전기 콘셉트모델중의 하나인 5MW급 OC3-Hywind를 해석하였다. 이 모델은 스파형 플랫폼을 가지고 있으며 3개의 현수식 계류삭으로 해저면과 연결되어있다. 수치해석프로그램으로는 NREL에서 개발한 FAST와 AQWA가 사용되었다. FAST에 입력되는 유체력은 AQWA를 통해서 계산되었으며, 운동특성으로는 전달응답함수와 평균운동, 상위1/3운동, 상위1/10운동을 평가하였다. 다른기관의 해석, 실험결과와 비교하였으며, 이 결과는 부유식풍력발전기 컨셉모델의 기초설계를 재해석하는데 있어 도움이 될것이다.

This paper introduces the design of low-power, fast-locking delay locked-loop using complementary pass transistor logic(CPL). Low-power design has become one of the most important in the modem VLSI application. CPL has the advantage of fast speed, high density, and low power with signal buffering between stages. Based on this analysis, we concluded that the I/O performance can be beyond 500㎒, 2-poly, 2-metal 0.65$\mu\textrm{m}$, 3.3V supply.

The RNA transcripts produced from in vitro transcription reaction of BTV core were analyzed on agarose-urea gel. Fast migrating abortive RNAs, in addition to full length species of RNA, were observed. Fast migrating RNAs extracted from agarose-urea gel were hybridized to all 10 segments of genomic ds RNA, while solw migrating RNAs extracted from agarose-urea gel were hybridized only to the large and medium size genomic ds RNA. These results indicate that fast migrating RNA transcripts are most likely the products of abortive transcription.

Fast Handover［1］ 프로토콜은 핸드오프 과정에서 발생하는 지연 시간을 줄임으로써 끊김없는 핸드오프가 가능하도록 해준다. 핸드오프 지연시간을 줄이기 위해서 Fast Handover는 링크 계층의 트리거 정보를 이용한 예측 기법을 사용한다. 따라서 기존 Mobile IPv6에 비해서 더 많은 시그널링 비용을 초래한다. 뿐만 아니라 가변적인 특성을 가지는 링크 특성으로 인해 예측한 정보가 정확하지 않을 수도 있고 이 경우에는 불필요한 버퍼 공간을 낭비하게 된다. 따라서, 이러한 부가적인 비용을 고려하여 Fast Handover와 Mobile IPv6의 성능을 비교, 평가하는 것이 필요하다. 본 논문에서는 두 프로토콜에서의 시그널링 비용과 패킷 전송 비용을 모델링하여 링크 계층 트리거의 시점이 전체 비용에 미치는 영향과 핸드오프 과정에서의 버퍼 요구량을 비교하였다. 그 결과 최적화된 핸드오프 성능을 위해서 트리거 시점을 적합하게 설정하는 것이 중요하다는 것을 알 수 있었다.
