Ecotourism has surged from conflicts between negative impacts of mass tourism and environmental issues. As an alternative tourism, ecotourism compromises extensively environmental, economic, educational, and cultural concerns. Ecotourism can be defined as environment-based tourism that ensures sustainable growth and development through conservation of natural and human environment, promotion of regional economy, and provision of tourism service in natural environment areas. Ecotourism should consider two key challenges; an effective means that may protect local economy through tourist-based income and improvement of residential circumstances, and role as leisure space that can improve tourist's experiences. The purpose of this study was to summarize ecotourism concepts through literature search and develop an ecotourism planning framework for Korean rural communities. In addition, developed planning framework in this study was applied to Jeongdori area, Wandogun, Korea as a case study in order to analyze its feasibility. A trial application in Jeongdori area demonstrated a possibility that ecotourism planning framework can be successfully adopted to a wide range of Korean rural communities. To ensure objectivity of framework, systematic case studies must be done in the future.

Urbanization and industrialization have led to a severe deterioration in urban air qualities. As an air pollution is closely associated with human health, citizen has a growing concern about the air quality policy to improve their residential environment. Due to the recently advance in web- and mobile computing technologies, citizens can easily access various air quality information and public authorities utilize the social media service to communicate citizens with air quality issues. Also citizens' participation and role has been increased to improve urban air qualities. Thus, to meet the technical and societal changes, a GIS-based air quality information system is developed based upon the Ubiquitous Public Access (UPA) model in ISO19154. The proposed system employs the context information model to provide air quality information depending on citizens' health conditions and locations. Also, citizens can present their perceptions of an air quality at their current location Public authorities can thus utilize the citizens' perceptions when establishing new air quality policies.

Purpose: The purpose of this study is to analyze the effect of sampling points on accuracy of storage reliability estimation for one-shot systems by assuming a weibull distribution as a storage reliability distribution. Also propose method for determining of sampling points for increase the accuracy of reliability estimation. Methods: Weibull distribution was divided into three sections for confirming the possible to estimate the parameters of the weibull distribution only some section's sample. Generate quantal response data for failure data. And performed parameter estimation with quantal response data. Results: If reduce sample point interval of 1 section, increase the accuracy of reliability estimation although sampling only section 1. Even reduce total number of sampling point, reducing sampling time interval of the 1 zone improve the accuracy of reliability estimation. Conclusion: Method to increase the accuracy of reliability estimation is increasing number of sampling and the sampling points. But apply this method to One-shot system is difficult because test cost of one-shot system is expensive. So propose method of accuracy of storage reliability estimation of one-shot system by adjustment of the sampling point. And by dividing the section it could reduce the total sampling point.

WBAN is short range wireless communication technology which is consists of several small devices close to, attached to or implanted into the human body. WBAN is classified into between medical and non-medical by applications based on technology and medical data with periodic characteristics is used the GTS method for transmitting data to guarantee the QoS. In this paper we proposed algorithm that resolve lack of GTSs while data transmit GTS method in superframe structure of WBAN. Coordinator dynamically allocates GTSs according to the data rate of devices and make devices share GTSs when lack of GTSs. We compared delay bounds, throughput for performance evaluation of the proposed algorithm. In other words, we proposed algorithm adaptive WFQ scheduling that GTS allocation support differential data rate in environments of WBAN. The experiment results show the throughput increased and the maximum delay decreased compared with Round Robin scheduling.

The human resource management is a very important thing to an airline call center. It may lead the call center to success or fail. The call center managers have to make appropriate decisions how many persons are inputted into the operation for each unit time and all day. In this study, a method is suggested to get an optimal staffing for each unit time using Integer Programming. The Integer Programming model can be used to solve the efficiency problem of the call center's staffing and scheduling. And call certer manager can adopt this model into the operations of the call center without any difficulties or modifications.

This study explored an appropriate research model that could explain and predict the spread of fintech, a new financial services in Korea. We reviewed two theoretical frameworks, theory of planned behavior(TPB) and technology acceptance model(TAM), which are frequently cited to explain human behavior and new technology adoption, respectively. Then, we proposed a decomposed theory of planned behavior(DTPB) as a research model and examined the model through PLS path modeling. As a result, every path except PEOU-ATT path in TAM is significant, and the explanatory power toward behavioral intention(R2=0.573) is also significantly greater in the proposed model. Accordingly, the proposed DTPB is appropriate to explain the spread of fintech in Korea. Finally, suggestions for the following studies are discussed.

Map is information media for human life. Recently, innovative map making technology has been developed and most updated various data are provided to map users. In consequence, use of maps is rapidly increasing in various applications. One of the examples is car navigation map because navigation maps provide reliable and necessary information with convenient way. Therefore, maps are to be changed to user-oriented from map making-oriented design. The main goal of spatial data infrastructure is to allow various users to access the real world information easily for decision making. However, most of the digital maps are focused on map making aspect such as providing up-to-date data, acquisition of accurate data with state-of-the-art technology, and addition of layers (For example, ortho-images and DEMs). If map data processing tools are to be provided with the digital maps, users could utilize maps for decision making without professional software or knowledge. Therefore, objective of this paper is to propose scheme of the digital map data processing service with application examples.

The quality of a veterinary service depends on the veterinarian's physical and mental health. However, a veterinarian's mental health is generally considered to be more vulnerable than that of other health care professionals. As many veterinary students will enter the veterinary profession in near future, it is necessary to investigate their psychological status. This study examined stressors affecting student life in one veterinary school. Anxiety, depression, and stress levels were assessed using questionnaires and qualitative research techniques. The results obtained from questionnaires showed that the proportion of veterinary students with psychological distress was higher than expected. The major stressors experienced by the veterinary students were academic, economic, and environmental. Qualitative study using a photovoice method revealed that the students in this study felt relatively deprived compared with those in other veterinary schools. In addition, they were distressed by the school environment and limited human relationship. Our results suggest that veterinary school administrators should be aware of students' psychological distress and should undertake systematic improvement in their educational system by altering counseling programs, curricula, and school culture principles.
