Purpose: Delivery food continues to grow. In the past, restaurant companies directly hired delivery workers to deliver food, but now, restaurant companies use delivery service platform companies to carry out delivery work rather than directly hiring delivery workers. Therefore, this study seeks to determine the impact of delivery food benefits in the restaurant industry on brand image, trust, and word-of-mouth intention. Research design, data, and methodology: To test the hypotheses of this study, 400 questionnaires were distributed and 340 were collected. Among these, 321 questionnaires, excluding 19 questionnaires that were answered insincerely, were used in the final analysis. Result. First, delivery food benefits were found to have a significant impact on brand image and trust. Second, brand image was found to have a significant effect on trust and word-of-mouth intention. Third, trust was found to have a significant effect on word-of-mouth intention. Conclusions: First, existing research focused on studying the attributes of delivery food in the restaurant industry, but this study studied the benefits that consumers can obtain through purchase among these attributes. Second, delivery food restaurants need to design promotions and advertisements in a way that displays coupons, points, or mileage. Third, quick delivery of orders can be a competitive advantage for delivery food restaurants.

This study purports to investigate the readiness of the university hospital employees in the knowledge-based management. Data were collected from 550 employees including administrative, nursing, and technical staff of 9 university hospitals located in Seoul and Kyunggi Province through the self-administered questionnaires. The response rate was 79% and 425 questionnaires were used as final data and analyzed using 2 test, t-test, and ANOVA. The main findings of the study are as follows. 1) It seems that most employees of the study hospitals have basic knowledge on the concept of knowledge-based management. This finding implies that the implementation of the knowledge-based management in Korean university hospitals will not likely to face strong resistance from their employees. 2) The results show that Korean hospital employees are still not so accustomed to using e-mail as the main communication tool. This finding suggests that it is necessary to use various communication tools which include electronic data interchange, teleconference, and cyber chatting for facilitating the knowledge-based management in Korean university hospitals. 3) It is desirable to appoint a chief knowledge officer(CKO) for operating knowledge-based management system effectively. 4) A reward system for employees who show a distinguished performance in the creation and sharing of new knowledge should be established. Knowledge mileage system, selection of the best knowledge employee and team will be a good example of the effective reward system. 5) The participation and support from the chief executive officers (CEO) of the hospitals is an important factor for successful knowledge-based management. Furthermore, to make physicians actively participate in the knowledge-based management is another important factor for obtaining valuable outputs from the system. 6) It is found that the knowledge and skills of the hospitals employees on the information technology (IT) are not sufficient for making knowledge-based management more popular. This implies that it is very important to select IT-oriented employees and educate them continuously on the knowledge-based management.

The purpose of this study was to analyze impact absorption function of midsole in cushioned marathon shoes. The foot is made up of a complex interaction of bones, ligaments, and muscles. These structures help the foot alternate between being a mobile, flexible adaptor and a stable rigid lever. The foot is broken down into two functional parts, the forefoot and the rearfoot. Cushioned marathon shoes for high arches have generous cushioning for efficient and high-mileage runners. Cushioned marathon shoes are made for feet that have high arches or no excessive motion and don't roll inward or roll outward. This condition is known as underpronation. Especially, Cushioned marathon shoes are designed to reduce shock and generally have the softest (or most cushioned) midsoles and the least medial support. They are usually built on a semicurved or curved last to encourage foot motion, which is helpful for underpronators (who have rigid, immobile feet). Cushioning marathon shoes recommended for the high-arched runner, whose foot may roll outward (supinate) rather than the natural slight inward roll, or whose feet may be relatively rigid. Cushioning shoes emphasize flexibility and usually are built on a curved or semicurved last to encourage a normal motion of the foot. Cushioning shoes usually offer no medial (inner foot) support. Cushioned marathon shoes have the single-density midsole, which is stable and relatively firm for a cushioned shoe, stays the same. But the forefoot is more rounded, and the rearfoot now includes a new and supportive rearfoot cradle. A foam midsole, perhaps with layers of different densities, to provide cushioning and shock absorption. EVA (ethylene vinyl acetate) and PU (polyurethane), the materials from which these foams usually are made. EVA is slightly softer than PU. EVA and PU may be layered together in a shoe, or a shoe may have more than one density of EVA.

과속운전은 교통심리학에서 안전과 관련한 중요한 관심사이다. 사망사고와 관련하여 높은 치사율을 보이는 위반행동 중의 하나이며 성, 연령, 주행거리와 같은 운전자 변인들의 영향을 받는 것으로 알려졌다. 그러나 이러한 인구통계적 변인들은 운전자들이 과속운전을 하는 심리적 기제를 충분히 밝히지 못할 뿐만 아니라 운전자 안전교육에도 도움이 되지 않는다. 따라서 본 연구에서는 인간 행동을 설명하는 이론들 중 가장 영향력 있는 이론인 계획된 행동이론(theory of planned behavior)을 중심으로 인구통계적 변인들을 통제하고도 과속운전 행동에 대한 태도와 주관적 규범 및 행동통제력 지각이 과속의도와 과속행동에 미치는 영향을 살펴보았다. 또한 과속운전과 같은 운전행동은 운전자의 의지와 상관없이 습관적으로 발생할 수 있으므로 과거행동이나 습관과 같은 변인들과 당위, 운전분노 및 충동성을 예측변인으로 위계적 회귀분석을 실시하였다. 연구 결과, TPB 변인들로 과속운전 의도와 행동의 예측이 유의하였을 뿐만 아니라, 당위와 운전분노를 제외하고 추가 변인들 모두 과속운전 의도와 행동의 설명변량 증분이 유의하였다. 마지막으로 본 연구의 제한점 및 과속운전중재 프로그램에 대한 함의를 논의하였다.

디젤 자동차의 배기가스 규제는 매년 지속적으로 강화되고 있다. 최근 HC, CO, NOx, PM에 대한 배기 규제는 매우 엄격한 기준을 적용하고 있다. 향후에는, 입자상 물질의 수량규제로 더욱 강화될 것으로 예상되고 있다. 이에 따라, 현재 대부분의 디젤 차량은 PM 저감을 위해 배기후처리징치(DPF)를 적용해 왔다. 엔진의 주행거리가 증가함에 따라, 엔진 배기가스에 포함된 재와 soot이 DPF내부에 축적된다. 축적된 재와 soot은 DPF 손상이나 엔진 성능 악화의 원인이 된다. 그러므로 효율적인 DPF의 클리닝은 엔진관리 측면에서 매우 중요한 부분이다. 만약 엔진이 주기적 클리닝을 통해 관리가 잘 된다면 엔진의 출력과 연비를 개선하고, 유지관리 비용을 절감할 수 있다. 따라서, 본 연구에서는 DPF 내부에 누적된 재와 soot을 효과적으로 클리닝 할 수 있는 고효율 DPF 클리닝 방법 및 장치의 개발을 수행하였고, 그 결과를 제시하였다.

Since American Airlines's mileage program emerged in market, loyalty programs have gained popularity. Many companies have generated many kinds of reward cards in order to induce precious consumers. As a result, reward cards are very important in consumer goods market and become diversified. In spite of its importance, little is known about how these cards influence consumer's perception. The prior research has not focused on reward card types and psychological variables. Accordingly this research intends to investigate psychological variables such as transaction coupling and sunk cost perception. According to the theory of regulatory focus, promotion focus consumers would point to gain-nongain frame work, but prevention focus consumers would point to loss-nonloss frame work. The paper proved the effect of reward card types and regulatory focus on transaction coupling and sunk cost perception. Based on the results from 2(type of card : visible vs invisible) ${\times}$ 2(regulatory focus: promotion vs prevention) between-subjects factorial design experiments, we found that consumer's transaction coupling and sunk cost perception of visible reward card are better recognized than invisible reward card. In addition, the results show that there is a significant interaction effect between the type of reward card and regulatory focus. Specifically promotion focused consumers tend to reveal better perception than prevention focused consumers in use of invisible cards. However, prevention focused consumers tend to show better perception than promotion focused consumers in use of visible cards. These findings will contribute to significant academic development and practically useful help to marketing managers.

Purpose - The purpose of this study is to clarify the difference of store attributes of Korean consumers and to analyze it's influence on consumer satisfaction in duty free stores which gain ground inch by inch in the distribution chanel. And it is to find discriminative result as compared with foreign consumer. Research design, data, and methodology - Subjects for the quantitative study, quota sampling was adopted in the Lotte, Shilla downtown and airport duty free stores from the first to 15^th December 2016 and 177 questionnaires from Koreans who had purchasing experience in off line duty free store were analyzed. The data was analyzed by using factor and reliability analysis, descriptive statistics analysis, the independent sample t-test and multiple regression analysis. To test consistency, Cronbach's alpha was used. Results - The result were as follows; 1. Korean consumers consider the importance of store attributes in duty free stores in order Product, Economic Feasibility, Convenience, Promotion, and Accessibility. 2. The meaningful impactive factors of duty free store attributes on consumer satisfaction turned out Product and Promotion. 3. These results show meaningful distinction between Koreans and foreigners in terms of consumer satisfaction in duty free stores. Conclusions - A marketer who is working for duty free store consider now that price benefit can not give strong impact to Korean consumers more and should concentrate on various brand assortment even including private brand. In terms of promotion, most duty free shops put special stress on foreign consumer's wants now as highly increasing of Chinese travelers but Korean consumer's sales portion and number of visitor also are steadily increasing. Therefore, a duty free marketer should prepare the Korean-oriented services with more enhanced promotion strategies for individual and group travellers, for example, a mileage service, VIP room and social network system to satisfy Korean consumers. In order to get satisfaction from Korean consumers, it makes effort on product and promotion than accessibility, price and convenience. Due to high level influence, further study is needed to enlarge to on-line market and to develop private brands for duty free stores.

Since mobile source is a major source of VOCs, quantifying emissions from motor vehicles is an important factor to control VOCs in atmosphere. In this study, in order to evaluate tailpipe VOCs emissions from motor vehicles, mass emissions of non-methane volatile organic compounds from 45 vehicles were determined. Measurements were made on a chassis dynamometer using CVS-75 mode and speed specific drive modes. Target VOCs are 53 compounds determined as the volatile ozone precursors. The individual VOCs composition of vehicle emission and emission rates were also determined. In case of gasoline vehicles, VOCs emission from over 80,000 km vehicles were about 46% larger than less 80,000 km vehicles. The difference in benzene and toluene according to driving mileage was 44% and 26% respectively. The composition of VOCs were different by fuel type. The order of VOCs composition was paraffins>aromatics>olefins in gasoline vehicle emissions, paraffins>olefins>aromatics in light duty diesel vehicle emissions. The VOCs emissions were decreased as vehicle speed increasing. These results will be used to calculate total VOCs emissions from automobiles in the future.

DEPs (diesel exhaust particles) like any other particles can be also inhaled into lung to participate in a damaging reaction to the organ. Possible damages might be apoptosis and inflammatory responses to the cells in respiratory track. The aim of this study was cytotoxicity evaluation of DEPs from five in-use diesel vehicles using a murine macrophage cell (RAW 254.7). We found that most DEPs have a considerable cytotoxicity compared to the control and SRM 2975. When measured by MTT assay and extents of apoptosis, DEPs of two highmileage vehicles had higher toxicity than those of the other three low-mileage vehicles tested. Although mRNA expression level of TNF-${\alpha$ somewhat explains the trend of cytotoxicity and apoptosis, that of IL-1$\beta$ did not. Correlation studies among the extents of MTT assay, apoptosis, and TNF-$\alpha$ expression showed that the extents between apoptosis and TNF-$\alpha$ expression was most highly correlated (r=0.96). These results suggest that cytotoxicity of various DEPs could be compared easily by measuring the extent of apoptosis or TNF-$\alpha$ expression by DEPs.
