PURPOSES : Daejeon is basically divided into an old downtown and a new downtown, and the recent relocation of the Chungcheongnam-do Provincial Government of Republic of Korea from the old downtown and the opening of governmental buildings in the new downtown as well have made this new downtown only densely populated with industrial and business facilities. Such changes in the downtowns have promoted the conditions of the new downtown while, consequently, dragging down the old downtown. Out of concern for those unbalanced developments of the two downtowns, Daejeon is now carrying out several city projects to revive the old downtown. In the light of that, as a part of the project to promote the old downtown, this study aims to conduct an evaluation on landscape of the culture and arts street in Daeheungdong which was built upon those ideas of a theme street project by Daejeon. METHODS : Based on the findings from the questionnaire not only on the components that would design the streetscape of the culture and arts street but also on the public satisfaction with the streetscape, the study defined how those changes in the components affect emotional factors of the pedestrians. In order to achieve the research goal, the study made changes in D/H ratio of the street structural components as well as the roadside trees. In terms of the questionnaire method, the study used the SD scale, and proceeded with its investigation through the frequency analysis, the principal component analysis (the factor analysis) and the structural equation model. RESULTS : According to the results from the factor analysis and the regression analysis, of those three factors, such as the openness, the comfortable sensation and the safety, the openness followed by the comfortable sensation and the safety was determined to have the most positive influence on the total satisfaction. The structural model analysis reported that the D/H and the structural components of the roadside trees and planting have a positive effect on the emotional image, and this emotional image also appeared to be positively related to the total satisfaction. CONCLUSIONS : This study looked into how the changes in the street structural components of the culture and arts street in Daeheungdong would affect the satisfaction with the streetscape, and finally confirmed that the D/H and the planting are what would have a positive effect on this satisfaction. What has been learned from this study will be the basic data to figure out how to promote and improve the culture and arts street in Daeheung-dong as this data will also help designing and developing of those specialized streets in other regions.

Over the past 20 years, constant progress in noise and vibration (NVH) engineering has enabled to constantly advance quality and comfort of operation and use of really any products - from automobiles to aircraft, to all kinds of industrial vehicles and machines - to the extend that for many products, supreme NVH performance has becomes part of its brand image in the market. At the same time, the product innovation agenda in the automotive, aircraft and really many other industries, has been extended very much in recent years by meeting ever more strict environmental regulations. Like in the automotive industry, the drive towards meeting emission and CO2 targets leads to very much accelerated adoption of new powertrain concepts (downsizing of ICE, hybrid-electrical...), and to new vehicle architectures and the application of new materials to reduce weight, which bring new challenges for not only maintaining but further improving NVH performance. This drives for innovation in NVH engineering, so as to succeed in meeting a product brand performance for NVH, while as the same time satisfying eco-constraints. Product innovation has also become increasingly dependent on the adoption of electronics and software, which drives for new solutions for NVH engineering that can be applied for NVH performance optimization of mechatronic products. Finally, relentless pressure to shorten time to market while maintaining overall product quality and reliability, mandates that the practice and solutions for NVH engineering can be optimally applied in all phases of product development. The presentation will first review the afore trends for product and process innovation, and discuss the challenges they represent for NVH engineering. Next, the presentation discusses new solutions for NVH engineering of products, so as to meet target brand values, while at the same time meeting ever more strict eco constraints, and this within a context of increasing adoption of electronics and controls to drive product innovation. NVH being very much defined by system level performance, these solutions implement the approach of "Model Based System Engineering" to increase the impact of system level analysis for NVH in all phases of product development: - At the Concept Phase, to be able to do business case analysis of new product concepts; to arrive at an optimized and robust product architecture (e.g. to hybrid powertrain lay-out, to optimize fuel economy); to enable target cascading, to subsystem and component level. - In Development Phase, to increase realism and productivity of simulation, so as to frontload virtual validation of components and subsystems and to further reduce reliance on physical testing. - During the final System Testing Phase, to enable subsystem testing by a combination of physical testing and simulation: using simulation models to simulate the final integration context when testing a subsystem, enabling to frontload subsystem testing before final system integration is possible. - To interconnect Mechanical, Electronical and Controls engineering, in all phases of development, by supporting model driven controls engineering (MIL, SIL, HIL). Finally, the presentation reviews examples of how LMS is implementing such new applications for NVH engineering with lead customers in Europe, Asia and US, with demonstrated benefits both in terms of shortening development cycles, and/or enabling a simulation based approach to reduce reliance on physical testing.

Cocoon production, which is a representative of traditional sericulture shifted into silkworm powder production in the spring of 1995. This, infect, signifies the change from the dress-centered textile business to the bio-industry and the functional resource industry. One of the most outstanding shifting is utilization of silkworm larvae for anti-diabetic agent. In Asian countries including Korea, silkworm powder derived from the domestic silkworm (Bombyx mori L.) has long been favored for anti-diabetic agent, but its efficacy was not tested until last decade by modern scientific methods. In this article, we reviewed the major researches on the silkworm powder as a blood glucose-lowering substance. After the beginning test of the efficacy of silkworm powder by a cooperative research between Department of Sericulture and Entomlogy, NIAST, RDA and Kyung Hee University, substantial data have been accumulated so far, In a serial experiment to select best condition, the fifth instar larvae prepared by freeze dry method turned out to have the best blood glucose-lowering effect. In the pharmacological experiment to understand the mechanism of silkworm powder in small intestine, the silkworm powder turned out to inhibit the activity of ${\alpha}$-glucosidase, by competitively binding to $\alpha$-type disaccharides. The animal experiment showed that the extract of silkworm powder prevents a rapid increase of blood glucose level after meal and prevents hunger and law blood glucose level during empty stomach. In the experiment to isolate the major component of silkworm powder, which exerts blood glucose-lowering effect, 1-deoxynojirimy-cin (DNJ) was eventually mass-purified, and it turned out that DNJ isolated from silkworm powder was excellent in its blood glucose-lowering effect. In the experiment to understand the personal difference of the efficacy of the silkworm powder, clinical candidates were divided on the basis of the criterion of traditional Chinese medicine: Tae-Yang, Tae-Um, So-yang, and So-Um. The result showed that silkworm powder has a tendency to reduce blood glucose level at fasting and at 2 hours after meal, and this trend was somewhat obvious in the Tae-Um body type. In summary, we reviewed scientific papers on the efficacy of silkworm powder and its purified DNJ as a blood glucose-lowering agent. These suggest that silkworm powder truly possesses blood glucose-lowering effect as documented in the traditional Chinese medicine, although further researches will be required to develop them as "medical" resource instead of functional food.

근래 들어 세계적으로 에너지에 대한 관심이 날로 증폭되어 가고 있다. 세계경제계의 화두 역시 녹색 에너지이고 각국 정부 역시 녹색 에너지를 경제회복의 선봉장으로 두고 있다. 한 국제연구소는 2030년까지 전 세계가 이 녹색 에너지 분야에만 투자하는 돈이 7조 달러로 한화로 환산하면 대략 7,000조원에 이를 것으로 전망하기도 하였다. 이에 우리나라 역시 이러한 녹색 에너지에 동참하고 있다. 전력을 생산하기 위해서는 전력 생산 시설과 연료 공급이 필수적이지만 공급에는 한계가 있다. 생산량을 증가 하는 것보다 더 중요한 것은 생산된 전력을 효율적으로 절감하는 것이다. 현재 사용 중인 에너지관리는 에너지를 소모하는 장비들의 효율적인 제어를 위하여 환경을 측정하여 설치된 장비를 조절하는 방법을 사용하고 있다. 그러나 에너지에 대한 절감 부분을 해결하기 위하여 국가나 기업체 등에서 많은 정책을 내놓았으나 번번이 해결되고 있지는 못하고 있는 현실이다. 본 논문에서는 에너지관리를 위하여 ICT기술을 이용하려고 한다. 에너지를 사용하는 환경의 변화를 최소화하면서 축척된 데이터를 활용한 방법으로 장비를 제어하는 스마트에너지관리시스템을 제안하고자 한다.

In this research, we measured the number of lanes, distance, disposition of apartment that are affecting the road traffic noise to evaluate the current condition of G city's road traffic noise. We decide on a basis regarding an apartment price formation factor, and the apartment current price and the results that compared. To have a point scale, we set the maximum road traffic noise at a 8 lane road for 5 points, give 4 points for a 6 lane road, which has a $2.1{\sim}2.5\;dB(A)$ difference compared to a 8 lane road, give 3 points for a 4 lane road, which has a $5.2{\sim}5.5\;dB(A)$ difference compared to a 8 lane road, and set 2 points for a 2 lane road and lower. If we set the standard floor plan as horizontal and a living room facing the roadside, the horizontal and living room facing the opposite side of the road is 1 point because it differs by 14.1 dB(A), and the vertical is 3 points since the difference is 5.3 dB(A). If we make grades by the distance, making standard the fifth floor with little soundproof effect from apartment to road, we observe a measurement below 2.9 dB(A) at a distance of less than 10 m and 5 dB(A), decreased at a distance of 20 m. Therefore, 4 points were given for less than 10m, 3 points for $10{\sim}20\;m$, 2 points for more than 20 m as we can apply the effect of a decay distance of line sound source and the decrease in noise effects of more than 6 dB(A), 1 point for more than 40m, and 0 points for more that 80 m since it is negligible. 28 apartments got 0 points because there is no effect of road traffic noise from other apartments, and 50 apartments where only the road at one side effect them got $5{\sim}10$ points. 4 apartments (17-2, 6-3, 10-4, 3-3) received over 20 points. 15 cases showed a difference between developer price and resale price, and 11 cases (73%) among them showed the same trend (price increases with a low road traffic noise restriction factor point) with the point of road traffic noise restriction factor. 4 cases demonstrated the opposite trend, showing price increases with a high restriction factor point. Among the 4 cases, case numbers 2,6 and 9 appear to be more affected by the location factor (business district) than the road traffic noise restriction factor, and case number 1 appears to be affected by the building factor (openness and direction).

Purpose - This study aims to examine the correlations between relationship benefits, quality, and continuity intention of community services. It further investigates the mediation effect of relationship quality operating on the association between relationship benefits and relationship continuity intention. Thus, this study will aim to elucidate the correlations between relationship benefits, quality and community services intention. Research design, data, and methodology - To achieve these objectives, this study executed a questionnaire from the users of the child․adolescent psychological support service which represents part of community services. The research framework that was utilized in this study was of three main factors. They were relationship quality, relationship benefits, and intention of relationship continuity. In relationship quality, factors such as trust and commitment was included in this section. For relationship benefits, factors such as society benefits and commitment benefits were the essence. The control variable in this study was gender, age, income, hours of service used, and the number of times service was used in community services. Results - The key research findings are as follows. First, this study found out that the more the social benefits was enhanced in the community services, the higher the relationship continuity intention was. Second, this study has found out that the higher the trust of community services, the higher the relationship continuity intention. Third, this study has shown that the more the relationship benefits was enhanced in the community services, the higher the recognition by the users' relationship quality was. Fourth, the trust in the community services played a mediating role between the relationship benefits and relationship continuity intention. Conclusions - Many associations could be discovered on the correlations between relationship benefits, quality, and community service continuality intention. These results will have important implications for the future of child and adolescent psychological support services. In terms of relationship marketing, the three factors; benefits, quality, and continuity intention in community services were proved to be pivotal. In order for the continuity intention in community services, the two factors of benefits and quality were the influential factors. From a policy maker's standpoint, the relationship continuity was the most important factor.

This study is an investigative study into the effects that the 'travel motivations' of participants on walking tourism has on their 'degree of satisfaction' by identifying tourist motivations for selecting walking tour among many types of tourism and their effects on hikers' degree of satisfaction. This study was conducted with hikers affiliated with 'walking on beautiful roads '-one of Busan's preliminary social enterprises- with a total of 176 copies used for a final effective sample. Data collected was analyzed using SPSS WIN 18.0 to conduct a frequency analysis of the sample. Along with exploratory factor analysis, Cronbach's ${\alpha}$ coefficient was used as an estimate of the validity and reliability of each factor. Multiple regression analysis was done for an analysis of travel motivations and their effects on satisfaction. The scale rates items in the questionnaire in the following categories: 'Motivations' for walking tours consist of 5 factors- vacation, soul-searching, social get-togethers, nature tour, community experience-with a total of 20 items. 'The degree of satisfaction' is made up of a factor with a total of 4 items. The results of the study are as follows: with respect to the hypothesis that motivations for walking tour would have a positive effect on the degree of satisfaction, test results show that 'motivations' have significant partial effects on the 'degree of satisfaction'. Motivations affect the degree of satisfaction in the order of nature tour and soul-searching except for experience and social get-togethers- an indication that participants on walking tours tend to travel for the attractiveness of nature, wanting time for reflection and meditation. As the first investigative study into participants in walking tours products offered by travel agencies, the study has the following implications for marketers: First, travel agencies selling walking tour products and government institutions concerned about the development of hiking trails need to discuss ways to make the most of natural resources as they are- rather than using development-oriented approaches. The study has its own limitation: it is that with the lack of domestic and international studies on walking tours, the study has not gained access to precedent studies on the subject so it has not established a systemic approach to the emerging type of tourism. Hopefully, this study will make a small contribution to its development.

Purpose - Following the speedy development of the smart phone industry, tourism companies started to increase their brand recognition and sales volume by adopting mobile applications. However, applications for tourism industries are still insignificant. This study tries to analyze empirical evidence from Korean and Chinese consumers who have used mobile tour applications. By using an expansion of the technology acceptance model (TAM), this study will find what factors have effects on user intention for mobile tour applications. The findings will be helpful for the development of mobile tour applications and the tourism industries. Research design, data, and methodology - This study uses the TAM, which was presented by Davis in 1989. This study uses consumer acceptance level, consumer choice attitude, and use intention as the basic variables to fit to the TAM, and adopts choice content quality, brand value, and usage motivation as additional variables to analyze. This study has developed several hypotheses and collected data from 620 users who used mobile applications for tourism during April 1 to April 30, 2015. A total of 612 valid questionnaires were collected and used in the data analysis. The data was analyzed with structural equation modeling using SPSS Win/pc and Amos 22.0. Results - The findings can be summarized as follows: First, the content quality affects the consumer acceptance degree and choice attitude. Second, the brand value has a directly positive effect on the consumer acceptance degree and choice attitude. It is clear that the content quality and brand value play important roles in raising consumer acceptance and choice attitude. Third, usage motivation has no effect on the consumer acceptance degree and choice attitude. Fourth, the acceptance degree does not have any effect on the consumer choice attitude. Fifth, the acceptance degree affects the use intention. Last, the consumer choice attitude affects the use intentions. This indicates that consumer acceptance and choice attitude must both be achieved to induce use intention among consumers. Finally, the effects of the mobile tour application content quality and brand value on consumer acceptance degree and choice attitude were confirmed. Additionally, the effects of the consumer acceptance degree and choice attitude on use intentions were analyzed. Conclusion - It is not meaningful for tourism marketing to launch tour applications in the mobile market without understanding tourism consumer characteristics. When developing mobile tour applications, companies should focus on the characters of consumer choice attitudes as high quality, high brand value, usefulness, and ease of mobile tour applications. This study has limitations in that it did not consider negative factors such as perceived risks or analyze whether there are differences between Korean and Chinese consumers. In the future, we will consider equipping the same mobile tour applications commonly used by both Korean and Chinese consumers, and then examine negative factors as well as the differences in mobile tour applications between Korean and Chinese consumers.
