The purpose of this study is to look at the development and status of Danish Agricultural Advisory Service (DAAS) and to find some implications on Korean agricultural and rural extension. Agriculture is main industry contributed to economic growth in Denmark. Main factors of this success would be strong farmers' organizations, commercial co-operatives, farmers' active participation in training and education, and independent advisory service owned and managed by farmers. DAAS has unique developmental history. First service was started by local farmer's organization in 1871. Farmers themselves wanted to start advisory service in order to improve the quality of butter. National center of DAAS was established in 1971 in order to disseminate knowledge to local centers, to develop new activities and computer programs, and to deliver in-service training of local advisors. In 2010, one national center with 550 employees and 32 local centers with 2,900 employes are serving for 48,000 farms. The service covers almost all farmers' needs such as production, finance, tax, buildings, crops, livestock, organic production, environment, legal matter. DAAS Academy tries to offer relevant, just-in-time training activities in order to develop the competences of advisors effectively.

Due to an explosive growth in services running in different datacenters, there is need for service selection and routing to deliver user requests to the best service instance. In current solutions, it is generally the client that must first select a datacenter to forward the request to before an internal load-balancer of the selected datacenter can select the optimal instance. An optimal selection requires knowledge of both network and server characteristics, making clients less suitable to make this decision. Information-Centric Networking (ICN) research solved a similar selection problem for static data retrieval by integrating content delivery as a native network feature. We address the selection problem for services by extending the ICN-principles for services. In this paper we present Queue and Latency, a network-driven service selection algorithm which maps user demand to service instances, taking into account both network and server metrics. To reduce the size of service router forwarding tables, we present a statistical method to approximate an optimal load distribution with minimized router state required. Simulation results show that our statistical routing approach approximates the average system response time of source-based routing with minimized state in forwarding tables.

The growth of Bandung's tourism industry has had a massive impact on the hotel sector. Most tourists visiting Bandung are domestic tourists and tend to be modest spenders fitting the profile of a mid-market (2/3 star) hotel guest. As competition has increased mid-market hotels have come under pressure from upmarket (4/5 star) and budget hotels committed to cutting prices. There is also competition with the mid-market hotel sector, which means that the 2/3 star hotels have to keep innovating in order to remain competitive. This study uses the Service Quality framework to describe customer expectations and identify gaps in hotel services. A questionnaire survey of 105 local tourists who had stayed in 2/3 star hotels in Bandung showed that the most important dimension is responsiveness, following by reliability, assurance, tangibles and empathy. Thus we conclude that local tourists' primary expectations are that hotels will deliver the service they have promised, be responsive to guests' needs and comply with service standards. Furthermore, these findings validate the earlier prediction that comparing 2/3 star hotel with 5/4 start hotel, the customers are having preliminary knowledge on facilities limitation and friendliness. Tourists using 2/3 star hotels tend to be prepared to accept limited facilities and less friendly staff service.

This study was conducted to investigate the effect of the factors of delivery app service failure on consumption well conflict emotion and complaining behavior targeting consumers with experience using delivery apps, and the results of the study are summarized as follows. First, when looking at the demographic analysis, the proportion of men was 58.1% and women were 41.9%, and the age group was the highest with 91.9% in their 20s. Second, as a result of testing hypothesis 1 that the factor of delivery app service failure will have a significant influence on consumer conflict emotions, failure to provide app information and failure to deliver/food service showed a significant positive (+) relationship. Third, as a result of the verification of Hypothesis 2, that consumer conflict emotions will have a significant effect on the consumer's continued use intention, it was found to be insignificant and rejected. Lastly, hypothesis 3 that consumer conflict emotions will have a significant effect on consumer complaints behavior is that negative word of mouth behavior, complaint behavior from service providers, and complaint behavior from service managers were adopted, but the complaint behavior was rejected by third parties.

This study examined the virtual methods of service delivery being deployed by librarians in private universities in Nigeria. The objective of the study was to analyse the virtual methods of service delivery among librarians and determine the predominant method used among the librarians. Survey research design was adopted for the study. Total enumeration technique was adopted for the study. A population of 181 librarians from 45 private universities in Southern Nigeria were involved. Data were gathered, analysed and presented using frequency counts, percentages, mean and standard deviation. The study found that librarians used different virtual methods of service delivery. Library website 157 (90%) and e-mail 132 (76.3%) were the prominent electronic media used by librarians while Facebook 59 (34%) and Whatsapp 57 (32.9%) were the predominant social media platforms applied for service delivery by librarians. Electronic media were more used for latest publications arrival, as well as library education and document delivery services while social media were more used for reference services and selective dissemination of information. In conclusion, virtual methods of service delivery were deployed by librarians in private universities for service delivery. In comparing the virtual methods, librarians used more of electronic media than social media to deliver services to their users. Therefore, electronic media were predominantly used than social media, many of the virtual methods were found to be underutilised while recommendations were proffered.

IT outsourcing studies have centered on the separate effect of formal contract and relational trust on IT outsourcing performance. In addition, previous studies ignored the importance of the relational capability that combine the formal contract and partnership can be able to deliver IT outsourcing effects. In this paper, we propose an IT governance commitment as a mediated role between relational capability and IT outsourcing performance. We collected data from 143 client companies of IT outsourcing and analyzed it using the PLS method. Our findings are revealed as following: At first, relational capability significantly and directly influence IT governance commitment as well as indirectly through formal contract and partnership. Secondly, IT governance commitment mediate between relational capability and IT outsourcing effect, and in turn affect IT outsourcing performance. The results and implications are further discussed.

MANET(Mobile Ad-hoc network) have recently attracted a lot of attention in the research community as well as in industry. Although the previous research mainly focused on various of MANET in routing, we consider, in this paper, how to efficiently support applications such as variable geocasting basd on MANET. The goal of a geocasting protocol is deliver data packet to a group of nodes that are located within a specified geocasting region. Previous research that support geocast service in mobilie computing based on MANET have the non-optimization problem of data delivery path, overhead by frequent reconstruction of the geocast tree, and service disruption problem. In this paper, we propose the mobility pattern based geocast technique using variable service range according to the mobility of destination node and resource reservation to solve this problem. The experimental results show that our proposed mechanism has improved performance of Accessibility & Network Overhead than previous research.

Mobile communication technology is advancing forward to deliver more connected devices and richer content and applications. The number of subscriptions continues to grow along with an explosive increase in the mobile data traffic demand. Thereby, it creates a significant network capacity shortage concerns for mobile network operators. In order to address this problem, it is essential to increase the network capacity at a low additional cost. The device-to-device (D2D) communication based proximity service is believed to have a promising future mobile communication technology that is capable to create new mobile service opportunities and offload traffic to the eNB. In addition, it is also required to develop new mobile communication services and its business models not only to accommodate the increasing mobile traffic demand but also to foster profitability of mobile business service providers such as the network providers, contents providers and platform providers. In this article, we first analyze current mobile business eco-system in the context of CPNT based value chain. Then, propose service development framework and business model creation methodologies for the device-to-device communication based services in the beyond LTE/LTE-Advanced systems.
