In this paper, we present integrated model of postal business that would be newly organized. The integrated model is developed through four phase. First, postal business is analyzed by three parts;collection, transportation and delivery. Second, the modeling criteria are developed that will be used for designing integrated postal business model. Third, object-oriented concepts are used by the steps of postal business modeling criteria captured. Finally, methods applied to developed model are grouped according to their function. Also, active-based mechanisms such as trigger and constraints are developed, and knowledge-based mechanisms such as inference are developed. These selected methods and attributes are encapsulated into objects. These constitute an object-active-knowledge based database model. Finally, Operational Scenario and Service Scenario are composed for real application according to proposed O-A-K model.

Purpose: The proficiency test was conducted to assess the performance of the dosimetry audit service provider in the readout practice of the dose delivered to patients in medical institutions. Methods: A certain amount of the absorbed dose to water for the high-energy X-ray from the medical linear accelerator (LINAC) installed in the Korea Research Institute of Standards and Science (KRISS) was delivered to the postal dose audit package given by the dosimetry audit service provider, in which the radio-photoluminescence (RPL) glass dosimeters were mounted. The dosimetry audit service provider read the RPL glass dosimeters and sent the readout dose value with its uncertainty to KRISS. The performance of the dosimetry audit service provider was evaluated based on the E_n number given in ISO/IEC 17043:2010. Results: The evaluated E_n number was -0.954. Based on the ISO/IEC 17043, the performance of the dosimetry service provider is "satisfactory." Conclusions: As part of the conformity assessment, the KRISS performed the proficiency test over the postal dose audit practice run by the dosimetry audit service provider. The proficiency test is in line with confirming the traceability of the medical institutions to the primary standard of absorbed dose to the water of the KRISS and ensuring the confidence of the dosimetry audit service provider.

이 논문에서는 소포 배달 서비스를 위한 인텔리전트 모니터링 시스템(Intelligent Monitoring and Control System; IMCS)에 대해 기술한다. IMCS 는 GIS, GPS 그리고 무선 통신 기술을 이용하여 택배의 접수와 배달 업무를 효율적이고 효과적으로 개발하기 위한 시스템이다. IMCS는 모두 세개의 서브 시스템으로 구성되어 있는데 접수와 배달 계획을 수립하는 PDPS(Pick-up and Delivery Planning System)과 접수/배달 현황과 차량의 위치를 파악할 수 있는 PDMS(Pick-up and Delivery Monitoring System), 그리고 개인휴대단말기(PDA)을 이용한 실시간 업무 처리 시스템인 MOCS(Mobile Operations and Communication System)으로 구성되어 있다. PDPS는 GIS와 최적화 알고리즘을 이용하여 접수와 배달을 위한 방문 순서와 경로 그리고 고객에게 방문할 예정시간 등을 생성한다. MOCS에서는 GPS와 무선 통신을 이용하여 업무 중 발생한 접수/배달 결과와 위치 정보를 실시간으로 PDMS에 전송하고 바코드 스캐닝과 전자 서명 등의 업무를 지원한다. PDMS에서는 수신한 정보에 따라 소포의 접수/배달 현황과 차량의 위치를 전자지도 상에 표현하고 업무 차량의 이동 궤적을 표시하여 계획된 경로와 비교하여 모니터링하고 관제할 수 있다. 현재 IMCS는 국내 한 우체국에서 시범 운영되고 있다.

Faster, safer and cheaper mailing of the postal matter is essential for surviving in the competitive market of home-delivery service. In the past, the domestic delivery business has been nu by only a few number of companies. But more and more number of companies including medium size ones are participating in the business, and the competition is getting severe. This paper proposes a method to select the optimal location of mail distribution centers that minimally connect the local mail centers of some major cities in Korea using the Steiner Tree theory, which is about connecting a finite number of points with a minimal length of paths and has been used in the distribution system optimization and optimal routing of the transmission lines of the electric power system. By using Steiner Tree theory in finding the best location of the postal delivery hub, we may expect the reduction of transportation cost and the increase of profit, resulting in acquiring the superior position in the competitive delivery business. It is expected that we may use the Steiner Tree theory in finding the best location of the electric power substation for the nott higher EHV(extreme high voltage) transmission network.

This study gropes for the way to seek a desirable leader increase the efficiency of the mail service in the post service administration. That is to say, this study presents an appropriate leadership for the enhancement of the post service administration by investigating the relationship of the leadership to the organizational commitment and job satisfaction in the post service organization. Consequently, for the mail business organization, the selling leadership and the participating leadership show strong positive (+) interrelationship with the organizational commitment, but weak positive (+) interrelationship with job satisfaction. On the other hand, the telling leadership and the delegating leadership show weak negative (-) interrelationship with the former. Here, we can learn that the selling leadership and participating leadership are more effective on the mail business organization.

Recently, the services using position information of moving objects is embossed. Theses services needs the moving objects databases to manage moving object data with efficiency. To build the moving object databases, we must develop the moving object engine to mange, store, and search the spatio temporal data of moving object. The moving object engine has to support query syntax to search data that suitable for user need like LBS, Telematics, ITS, vehicle management system. In this paper, we design and implement the moving object engine to support service with moving object data. The moving object engine is able to support system environment that users are able to get the moving object data easily even they don't know complex data structure.

An efficient image processing algorithm is proposed to recognize both the height and width modulated barcodes which are rotated and printed at an arbitrary position. The main feature of this algorithm is to utilize the gradient information of a rotated barcode with a Sobel operator. The barcode area is extracted using the gradient information, and the barcode is decoded from the binary image of the extracted area. Theis algorithm is successfully applied to the 4 state and width modulated barcodes. It takes 0.86 secoden to process a letter, and the recognition rate reaches above 98% under various testing conditions. Since both the width and height modulated barcodes are processed with the proposed algorithm, it can be applied to postal service automation.

Drones are now widely used in civilian applications such as filming, leisure, agricultural control, monitoring, and the generation of 3D-spatial information, deviating only from military drones. In the field of logistics, prototypes are emerging in the area of logistics transportation, and to develop a future transportation service under the name of a drone tax, each country is introducing its first flight results using its own unique drones. In this paper, we review the domestic and overseas trends of drone delivery service technology, which requires various capabilities such as automatic flight, and review the related core technologies. We then propose the flight capability and road map of a drone delivery service according to the detailed conditions such as the flight area, visibility, and flight method. Additionally, in connection with the postal processing of the Korea Post Office, which would be a main demand for this type of service, we describe a method for realizing a drone delivery service based on the structure, scenario, and deployment of the drone delivery system.
