Request for network becomes complicated gradually and network traffic is increasing, To overcome this situation, the structure of network node should be changed to accept new service quickly and economically by executing program code in node itself. Active Network's research can use net resources more properly because of executing program within node itself. In this paper, we design a programming language, namely ASL, for Active Sensor to describe function and behavior of active sensor. We also design and implement the interpreter for proposed ASL.

Active ingredients have been around in cosmetics for a long time but have they really resulted in active cosmetic products\ulcorner In order to achieve this, the right active needs to be delivered to the right location at the right concentration for the correct period of time. And the extent (and therefore the concentration) of this delivery depends on the formulation. From a rather theoretical approach based on the polarity of the active ingredient, the stratum corneum and the oil phase, the Relative Polarity Index was established that enables the selection of a suitable emollient for ensuring skin penetration of the active ingredient. Practical examples subsequently show the validity of this approach that demonstrates that one can regulate the delivery of an active molecule (and therefore the efficacy of a cosmetic formulation) by selection and control of the emollient system. Cosmetic formulations are generally quite complex mixtures and subsequent experiments using different emulsifier systems indicated that this component of a cosmetic formulation could also have an impact on steering the active ingredient to the right layer of the skin, although it is too early to be able to derive general rules from this.

In order to improve e-Trade service, this paper has deduced impeding factors after review of precedent research on e-Trade and analysis of e-Trade current status. Then an empirical analysis of whether variables deduced are detrimental factors to utilization of e-Trade service has been made on the basis of a research model and relevant hypotheses. The scope of e-Trade service indicated in this paper is limited to use of uTradeHub system. Analytical results for the improvement of e-Trade service clearly indicate that the higher the impeding factor to utilization of the system integration, logistics and customs clearance, marketing and users field, the more necessary the service improvement for invigoration of e-Trade service. However, foreign exchange field does not seem to require attention because SMEs have not active will to do electronic payment through the process of electronic documents.

In the field of Internet of Things (IoT), smarter embedded devices offer functions via web services. The Quality-of-Service (QoS) prediction is a key measure that guarantees successful IoT service applications. In this study, a collaborative filtering method is presented for predicting response time of IoT service due to time-awareness characteristics of IoT. First, a calculation method of service response time similarity between different users is proposed. Then, to improve prediction accuracy, initial similarity values are adjusted and similar neighbors are selected by a similarity threshold. Finally, via a densified user-item matrix, service response time is predicted by collaborative filtering for current active users. The presented method is validated by experiments on a real web service QoS dataset. Experimental results indicate that better prediction accuracy can be achieved with the presented method.

The physical therapist's participation in community based rehabilitation(CBR) is necessary, in a variety of ways, to ensure the disabled quality service. Although CBR needs the Physical Therapist's help, participation is limited due to unstable CBR policy, and because there is a lack of financial support, skilled Physical Therapist's are usually not hired. Physical Therapist's themselves do not seem to completely understand this. The experts active participation is needed for effective rehabilitation service. Therefore, the trained Physical Therspist's participation is absoutely necessary is CBR policy if it is even to provide completely effective service.

The purpose of this study is to understand what is ActiveX control and how to utilize it in developing dynamic web pages. For this purpose, some literature survey and experimental practices with PC were done to understand the differences among web programming technologies such as visual basic, java, XML web services. In order to scrutinize the functions of ActiveX controls and the comparison of their technology with currently introduced XML web service, a study on the history of Internet programming with a focused view on ActiveX control was also performed. With the knowledge of the fore mentioned, Actual design and building experiments of web pages using ActiveX control pad were implemented. The results show that Microsoft ActiveX controls, formerly known as OLE controls or OCX controls, developed to compete with java applet in internet battle fields, turn out to be useful in software reusability, cost-saving and time-saving etc. However, the use of ActiveX controls has been confined in window platform, Overall, this study was useful for understanding the usage of ActiveX controls in web pages.

This study aims to provide alternative strategies for promoting active engagement of users in participatory archives. It focuses on users and their active participation in digital archives beyond providing simple participation opportunities. In doing so, the study reviewed relevant literature that analyzes interpretation and development of participatory digital archives. Moreover, it examined several cases of participatory digital archives as to how they apply for user participation, policy, and service. As a general property, main participants, duration, and technology were examined. Technology was further subdivided into open source software, availability of Open API, availability of mobile web, and offline archives. Participation method was divided into active participation, hub participation, and passive participation according to degree of user participation, and the participation functions provided by each archive were compared and analyzed. In policy area, terms of use, personal information processing policy, copyright policy, collection policy, major collections, scope of collections, classification methods, and descriptive elements of each archive were discussed. Services were divided into content, search, and communication area. Based on such analysis, this study proposed ways for promoting active engagement of users in participatory digital archives in terms of participation, policy, content service, and communication service.

In recent years, the user demands have increased for multimedia service of high quality over the broadband convergence network. These rising demands for high quality multimedia service led the popularization of various user terminals and large scale display equipments, which needs a variety type of QoS (Quality of Service). In order to support demands for QoS, numerous research projects are in progress both from the perspective of network as well as end system; For example, at the network perspective, QoS guaranteeing by improving of internet performance such as Active Queue Management, while at the end system perspective, SVC (Scalable Video Coding) encoding scheme to guarantee media quality. However, existing AQM algorithms have problems which do not guarantee QoS, because they did not consider the essential characteristics of video encoding schemes. In this paper, it is proposed to solve this problem by deploying the TS- AQM (Temporal Scalability Active Queue Management) which employs the differentiated packet dropping for dependency of the temporal level among the frames, based on SVC encoding characteristics by exploiting the TID (Temporal ID) field of the SVC NAL unit header. The proposed TS-AQM guarantees multimedia service quality through video decoding reliability for SVC streaming service, by differentiated packet dropping when congestion exists.

This study takes an effort to suggest solutions for medical service consumers' sovereignty. Specifically, consumer evaluation, information seeking level, and affecting factors on information seeking level were explored in terms of medical service. In present study, medical information included medical institution and doctors, prescription, diseases, medical treatment and medical expense. Medical service consumers' information seeking is identified as consumers' own efforts to acquire medical information through various sources. The analysis results suggested that consumers' information seeking level is even lower, while their evaluation level is somewhat low. Moreover, the result for information seeking level by consumer characteristics implied that people who have high education, high economic status, medical knowledge, and high attitudes for consumer right are active information seekers. Finally, consumer attitudes for right appeared most influential factor on information seeking level, implying direction for medical service consumer education.

Empirical studies have shown that government and human service nonprofit organizations have maintained active partnerships to deliver human services for the past several decades. However, the previous researches on resource dependent government-nonprofit service delivery have revealed serious methodological limitations to adequately demonstrate the dynamic relationship between both sectors over time. Since the dynamics underlying the government-nonprofit service delivery is a complex process, in which multiple factors dynamically interact over time, the assumptions of system dynamics can help improve these methodological drawbacks. This study aims to explore methodological issues and weaknesses observed in empirical studies on resource dependent government-nonprofit service delivery in the United States, and further attempts to provide insights on future research toward a dynamic approach, bringing the assumptions of system dynamics to the challenges of the previous researches.
