Under part load condition of spark-ignition engine, pumping loss had great effect on engine efficiency. To reduce pumping loss, the study designed spark-ignited engines to make direct spray of gasoline to combustion chamber. In spark-ignited direct-injection engines, ignition probability is important for successful combustion and flame propagation characteristics are also different from pre-mixed combustion. This study designed a visualization testing device to study ignition probability of spark-ignited direct-injection LPG fuel and combustion flame characteristics. This visualization device consists of combustion chamber, fuel supply system, air supply system, electronic control system and data acquisition system. Ambient pressure, ambient temperature and ambient air flow velocity are important parameters on ignition probability of LPG-air mixture and flame propagation characteristics, and the study also found that sprayed LPG fuel can be directly ignited by spark-plug under proper ambient conditions. To all successful cases of ignition, the study recorded flame propagation image in digital method through ICCD camera and its flame propagation characteristics were analyzed.

In this study, the structure model including the role of servicescape focusing on service participation and customer experience in theme park service is demonstrated empirically. The servicescape construct of theme park service includes three factors such as ambient atmosphere, functionality and layout, and sign, symbols etc. Customer service participation includes suggestion, passion and citizenship. And the emotional and convenience factors are included to customer experience. As an analysis result of examining the 241 respondents of university students, some implications were described. Customer satisfaction is greatly influenced by customer's participation in theme park service, and customer's participation has a significant effect on improving customer satisfaction by inducing customer experiences. It is desirable to consider servicescape priority in order of signs and symbols, ambient atmosphere, functionality and layout factor. The customer's participation in service is a passion for participation, citizenship, and suggesting for problems or improvements. Therefore, participants in planning and designing servicescape in the future, including IT services, should be creative in the direction of inducing various participations of customers and creating positive experiences for customers. In order to apply these findings to the composition of servicescape, the participation of various experts is required. Also, the expertise and competences of various fields must be gathered for each issues, and a more creative and scientific approach is required.

This study was designed to evaluate the exposure to benzene by residents in neighborhoods near a major roadways, by persons waiting buses, and by drivers and service station attendants while refueling. It was confirmed that the outdoor air benzene concentrations near the major roadways were higher than those further away from the sources. However, neither the indoor air nor breath concentrations were different for two specified residential areas. Smoking was confirmed as an important factor for the indoor air benzene levels. Persons waiting buses, drivers and service station attendants were exposed to elevated benzene levels compared to even the residents in neighborhoods near a major roadways. The mean benzene concentration at bus stop was 2.7 to 6.9 times higher than the mean ambient air concentration. The mean benzene concentrations in the breathing zone of drivers and service station attendants were 95 to 160 and 120 to 202 times higher than the mean ambient air concentrations, respectively.

사용자는 자신이 원하는 상품 또는 그와 관련된 상품을 비교해보고 구매하기 위해, 일반적으로 여러 상점들을 방문한다. 만약 이런 상점들의 위치정보를 제공하는 서비스가 있다면, 상점가를 헤매는데 소모되는 불필요한 노력과 시간을 줄일 수 있다. 그리고 주변에 어떤 종류의 관련상점들이 있는지 파악할 수 있어서 구매의 폭을 넓힐 수 있다. 이로써 사용자는 효율적인 구매활동을 할 수 있을 것이다. 본 논문에서는 이처럼 사용자에게 관련상점들의 정보를 효율적으로 제공하기 위한 목적으로, "구조화된(구매관련) 정보공간, 실생활 공간, 엠비언트 정보공간"의 3-계층으로 구성되는 엠비언트 서비스 모델을 제안한다. 제안한 모델은 웹으로부터 자동으로 수집된 상점정보를 구매라는 측면을 고려하여 그룹화 및 구조화한다. 그리고 사용자가, 자신의 상황을 통해 자동으로 생성되는 엠비언트 쿼리를 이용하여 관련상점정보를 검색할 수 있게 한다. 최종적으로 사용자는 관련상점정보를 지도상에 계층구조 형태로 획득하며, 이를 이용하여 다른 종류의 관련상점정보를 추가적으로 검색할 수 있게 한다. 결과적으로, 제안한 모델을 통해 사용자는 복잡한 검색과정 없이도 직관적인 형태로 관련상점들의 정보를 획득할 수 있다. 이 모델은 실생활 공간에 존재하는 상점 이외의 다양한 객체들에 대해 관련객체들의 정보를 제공하는 서비스 개발에도 활용할 수 있을 것으로 전망한다.

It has been proved that information and communication technology (ICT) solutions for personalized health (PHealth) and ambient assisted living (AAL) can support people in their daily life activities. Several solutions have been demonstrated to empower different levels of services through seamless data acquisition and specific users' interaction modalities. Usually services usability and accessibility are handled in the design process and are validated with small users' groups. Moreover, while service design and systems development have been extensively described in literature, service deployment methodologies are not properly addressed and documented. Proper reference guidelines are also missing. The most common methodologies like unified process (UP) or ICONX can cover only the design and the development of PHealth services without a clear description on the following phases such as deployment, service provision and maintenance. These phases present several risks to be taken into account right from the beginning of the implementation of PHealth or AAL services. This paper focuses on the description of a structured methodology to deploy PHealth services and how this process can be supported by integrated software routines and adapting the UP framework in particular the "Transition phase."

The paper summarizes the dynamic-based assessment of a reinforced concrete arch bridge, dating back to the 50's. The outlined approach is based on ambient vibration testing, output-only modal identification and updating of the uncertain structural parameters of a finite element model. The Peak Picking and the Enhanced Frequency Domain Decomposition techniques were used to extract the modal parameters from ambient vibration data and a very good agreement in both identified frequencies and mode shapes has been found between the two techniques. In the theoretical study, vibration modes were determined using a 3D Finite Element model of the bridge and the information obtained from the field tests combined with a classic system identification technique provided a linear elastic updated model, accurately fitting the modal parameters of the bridge in its present condition. Hence, the use of output-only modal identification techniques and updating procedures provided a model that could be used to evaluate the overall safety of the tested bridge under the service loads.
