"Domestic delivery service" is defined the service to deliver goods or packages from point of senders to point of receiver. With the characteristics of door to door, it is must a service provider should know the exact location of destination assuring best utilization of moving path. Generally, location information consist of postal code and address only, which result in difficulties to identify the precise location of destination. It is relatively less correlated between the information that address refers and practical location in Korea address system. For example, the next door to house number 100 is not always house number 101. Therefore, a delivery man additionally uses a paper map or a GPS navigation which carry extra job to input every code of location to the device in order to know precise location. It is also very inconvenient that every delivery man identify the location that address information refers and make a personal decision of the optimum moving path dropping each destination without calculating provisioning process of whole delivery path. As explained above, it is inefficient to find information delivery service required and to generate the optimum path. In results, these difficulties bring in delay of service and increase of cost. In this point, the contents of the thesis suggest a GPS navigation system easy to obtain accuracy of delivery information which enables to automate optimum moving path based on RFID which contains location information.

This study proposes a new model of tourism destination management based on the tourism management program using information and communication technology provided by LBS. The personalized tourist information service can enhance the satisfaction of tourists. Sustainability can be expanded through management based on the capacity of the tourism destination. Increased satisfaction leads to more diverse tourism activities. Various tourism activities increase the consumption expenditure, which satisfies the local tourism destination management purpose. The tourism destination management plan of the central and local governments is a comprehensive system in which detailed policy support plans are formulated from the perspective of the three requirements for sustainability-economic, socio-cultural, and environmental-and concerned parties are connected and resources are supported through detailed processes in which the sources of disparities in accessibility are identified and the roles are delegated at the national, community, and regional levels.

본 논문에서는 LBS를 이용한 지하철 이용 서비스를 제안한다. 이 서비스는 지하철 내부에서 자신의 정확한 역 내 위치를 추적하고 공유할 수 있도록 하여 이용자의 편리성을 극대화 한다. 이 서비스는 GPS와 모바일통신 기술을 기반으로 하여 지상/지하 관계없이 사용자 자신의 위치를 추적함으로서 공간의 이동에 따른 서비스제약을 최소화 한다. 단순히 현재 위치를 실시간으로 제공하는 것을 목적으로 하는 것이 아니라 추출한 위치를 기반으로 목적지까지의 보다 정확한 도착시간, 잔여시간, 남은 정거장수, 알람시간 등의 정보를 제공하여 기존 서비스에서 더욱 고급화되고 향상된 서비스를 제공한다. 본 논문에서는 google map, naver map등의 open API를 이용하여 지도상에서만 제공하는 지하철 LBS보다 응용력 및 서비스 품질 면에서 우수함을 보인다.

This paper proposes a routing algorithm that determines the optimal path using deep reinforcement learning in software-defined networks. The deep reinforcement learning model for learning is based on DQN, the inputs are the current network state, source, and destination nodes, and the output returns a list of routes from source to destination. The routing task is defined as a discrete control problem, and the quality of service parameters for routing consider delay, bandwidth, and loss rate. The routing agent classifies the appropriate service class according to the user's quality of service profile, and converts the service class that can be provided for each link from the current network state collected from the SDN. Based on this converted information, it learns to select a route that satisfies the required service level from the source to the destination. The simulation results indicated that if the proposed algorithm proceeds with a certain episode, the correct path is selected and the learning is successfully performed.

Mobility services need to change according to the regional characteristics of the target service area. Accordingly, analysis of mobility patterns and characteristics based on Origin-Destination (OD) data that reflect travel behaviors in the target service area is required. However, since conventional methods construct the OD data obtained from the administrative district-based zone system, it is hard to ensure spatial homogeneity. Hence, there are limitations in analyzing the inherent travel patterns of each mobility service, particularly for new mobility service like Demand Responsive Transit (DRT). Unlike the conventional approach, this study applies a data-driven clustering technique to conduct spatial analyses on OD travel patterns of regional mobility services based on reconstructed OD data derived from re-aggregation for original OD distributions. Based on the reconstructed OD data that contains information on the inherent feature vectors of the original OD data, the proposed method enables analysis of the spatial characteristics of regional mobility services, including public transit bus, taxi and DRT.

Recently the mobile terminals using GPS offer find-way service. But for obtaining the simple small-map, this system is very additional expensive. Accordingly it is impossible to provide this service using the general mobile terminals which almost all of the people have. Therefore, in this paper we design and develop the mobile outline map and guide map to solve the problems of the existed find-way service in the mobile environments. This system supports the mobile guide service of the destination without the additional cost on mobile terminal based on WIPI at any time and any where. And mobile service providers are able to advertise for neighborhood stores of the searching destination using this system.

Purpose: The purpose of this study is to investigate the relationship between service quality, destination image, and tourist satisfaction for foreign tourists visiting Korea, and in particular, to analyze the moderating effect of psychological power in the relationship. Research design, data, and methodology: A research model was derived through existing literature research and a survey was conducted on foreign tourists visiting Korea. Structural equation model of SPSS and AMOS24.0 were used for data analysis and hypothesis testing. Results: The tourism service quality affects the image of tourist attractions. Images of tourist attractions were found to affect tourism satisfaction. It was found that the lower the psychological power, the greater the effect on the relationship between service quality and image, and the relationship between image and satisfaction. Conclusions: This study demonstrated that service quality at travel destinations is a key factor in order to enhance the image and satisfaction of Korean tourist destinations for foreigners visiting Korea. On the other hand, since the image and satisfaction level of the tourism destination vary depending on personal factors such as psychological power, it suggests that travel industry workers or researchers should develop and operate services tailored to the individual characteristics of the tourists.

This study compares the results of two Importance-Performance Analyses (IPA) on the convention destination images in Korea by meeting and exhibition planners. Meeting and convention planners carefully evaluate convention destinations by considering meeting room facilities, hotel service quality, safety/security, air transportation access and hotel room availability as the most important attributes of a convention destination. On the other hand, night life, exhibition facilities, scenery/sightseeing opportunities, food and lodging costs and restaurant facilities are considered as the least important attributes of a convention destination. The study revealed that convention destination attributes ranking is dynamic and continuous evaluation should be done to determine the current perception of the meeting and exhibition planners. Meeting and exhibition planners' importance grid of the convention attributes is dynamic and changed with the environment and needs of their clientele. In this study it was noted that the ranking for some attributes has dramatically changed.
