The early test can greatly reduce the cost of error correction for system development. It is still important in SOA based service system. However, the existing methods of test case generation for SOA have limitations which are restricted to only web service using XML. Therefore, this paper proposes a method of test case generation using BPMN-based model reduction for service system. For minimizing test effort, an existing BPM is transformed into S-BPM which is composed of basic elements of workflow. The process of test case generation starts with making S-BPM concerning the target service system, and transforms the target service system into directed graph. And then, we generate several service scenarios applying scenario searching algorithm and extract message moving information. Applying this method, we can obtain effective test cases which are even unlimited to web service. This result is the generation of test case which is reflected in the business-driven property of SOA.

NOTAM is an announcement that is distributed to flight attendants with status information related to aviation. ICAO, the International Civilian Aviation Organization, recommends that a NOTAM service be provided for the SBAS service in order to use the SBAS signal-based access procedure. To comply with ICAO recommendation, KASS must provide NOTAM service to all aircraft landing using SBAS signal in order to provide APV-I SoL service. Therefore, it is necessary to develop KASS NOTAM system to provide KASS NOTAM service. In this paper, we analyzed the regulations related to NOTAM in Korea and abroad and analyzed the present state of NOTAM service in Korea. Based on this, we propose a method of providing KASS NOTAM service. We analyzed the NOTAM system of WAAS in the US and EGNOS in Europe and analyzed the main functional requirements of the KASS NOTAM system.

The Internet is extremely important to accomplish numerous items, from education to businesses and entertainment. Therefore, the quality of its performance must be efficient. Nowadays, there is a lack of information available for users to choose a suitable Internet service. What information is available might be insufficient, inaccurate, or regularly updated. Accordingly, there is a need to develop an electronic system that enables users to evaluate their current Internet service subscription. Several factors are used as evaluation criteria in the system that affect users' decisions. In this paper, a prototype of a design science research project is proposed to address a few objectives. First, it can help Internet service users in Saudi Arabia to make the best decision for themselves regarding Internet services subscriptions. Second, it can assist the Saudi government to seek one of the 2030 vision goals: the digital transformation that depends on having a good Internet connection. The proposed solution is a promising one that would help Internet service users to make the best decision for themselves and choose the best Internet service that fits their needs. A qualitative method has been used to evaluate the efficiency and the utility of the proposed system prototype. The results showed the extent of participants' acceptance of the Internet Service Evaluation System.

Since the provision of Permanent Affordable Housing in the early 1990's, it is confronted with the need to strengthen its welfare service due to aging of its facilities and the declining welfare system for its tenants. In addition, the aging population of tenants is on the rise, increasing the group of tenants that are in need of care. The local social community center has entered into the community of permanent affordable housing and takes partial responsibility in the tenant's social welfare. However, social community center is mainly responsible for providing welfare service to its local residents and thus limited in its ability to satisfy welfare service to tenants of permanent affordable housing. Therefore, it is required to renew the existing welfare system to better suit social demands of tenants according to its specific social group and the characteristics of housing complex. This study aims to propose methods that can strengthen welfare service and analyze the characteristics of welfare service by investigating the existing conditions of welfare system for the tenants in permanent affordable housing complex. For this purpose, this study presents with categories of service standards, by breaking down and codifying welfare service and propose applicable mixed-use service in pre-existing permanent affordable housing.

In this paper, we propose a management system for positioning and indicating the surveyed control point using RFID and UMPC. This system is composed of digital control point, management system and application. The digital control point transmits information of the surveyed control point and the management system receives the data from the digital control points and manages the scattered digital control points. The system offers three services for managing the surveyed control point. The first service is control point monitoring service for identifying the change of location, locating the missing control point and the second service is control point search service notifying selected control point to user, and the third service is control point land management service for editing the control point information in the land. Therefore, this system makes it easy for administrators to access the control point information of the scattered surveyed control point through the country and enhances the managing efficiency.

Customer service process is one of the most important processes in today's competitive business environment. Among the various activities of customer service process, equipment malfunction diagnosis activity should be performed fast and accurately. When a customer calls the service center and reports the observed symptoms, he/she describes them in layman's terms. Therefore, the customer-reported symptoms have not been considered helpful information for service representatives. However, in order to perform diagnosis activity fast and accurately, we need to make use of the customer-reported symptoms actively. In this research, we developed three systems called R-EMD (Rule-based Equipment Malfunction Diagnostic system), C-EMD (Case-based Equipment Malfunction Diagnostic system) and R&C-EMD (Rule & Case-based Equipment Malfunction Diagnostic system), each of which diagnoses equipment malfunctions using the customer-reported symptoms. R&C-EMD is a hybrid system that utilizes both rule-based and case-based technologies. The diagnosis rules used in R&C-EMD and R-EMD were not acquired from service manuals or interviews with service representatives. Rater, we extracted them directly from the past diagnosis cases based on symptoms' frequencies. By this way, we were able to overcome the knowledge acquisition bottleneck. Using the real 100 malfunction diagnosis cases, we evaluated the performances of R&C-EMC, R-EMD and C-EMD in terms of speed and accuracy. In diagnosis time, R&C-EMD took longer than R-EMD and shorter than C-EMD. However, R&C-EMC was the best in accuracy.
