Although motorcycle safety studies to date have identified the causes of motorcycle accidents in general, very few have investigated postal motorcycle accidents by studying the delivery postmen's specific work environment. To better understand postal motorcyclists' driving behavior associated with their delivery workload, we developed a system using V-World platform which visualizes driving behavior in real time along the driver's delivery route throughout an entire work day. We conducted a field test to examine the feasibility of our system by involving six delivery postmen currently working in Songpa, Seocheongju, and Gangseo, respectively. To show the potential of our system for nationwide comparison of postal motorcyclists' driving behavior and their workloads, we present several sample analyses using the collected field data. Although ideally, postmen's workloads should be standardized nationwide, we found large variation depending on regional characteristics of work area which affects postmen's driving behavior.

Currently the amount of general letter mail in Korea is on an increasing trend; especially it shows the seasonality that is concentrated in the end of the month or the year. However, the situation is not treated appropriately Moreover. manpower insufficiency if the carriers causes the poor service and the heavy burden of work. Under the existing conditions, the various efforts such as development of the automatic sequence sorting system and construction of the address database are given in order to quicken mall process and lighten the carriers' burden But the inconsistent addressing and the various expressions of address drop the systems and the carriers off in efficiency. In this study, we present the Korean postal addressing standards to make it possible to improve the performance of address recognition and help postmen to sort the mail; particularly focusing on the substance. After analyzing the domestic system, the information structure and the problems of postal address, we propose four fundamentals and the standards including synonyms and acronyms. In addition, we suggest several considerations for mail format. We expect that this study could support the postal service in Korea as a basic standard.

Uniform is the dress of distinctive design or fashion worn by members of a particular group or serving as a means of identification. The postman's uniform of Ministry of Communication should be distinctive or characteristic clothing to provide high functionality and symbolization of job characteristics, cost effectiveness and esthetic. In order to design the postman's new uniform available in 2000, there has been a satisfaction survey to 1,116 postmen. A thorough analysis of survey and informal and face-to-face discussion with postmen give the direction of design concept. One of the most important things in the design concept is to make the uniform high quality & refinement. The style is a refined jumper suit in consideration of form stability, wearing satisfaction, convenience in activity. The basic colors selected are navy and medium gray. The colors of jumper are MOC red ; C.I color Green : a representative color of youth, white : a symbolic color of bright future. All three colors are plaid on a basic nary color. In the selection of the textile, synthetic fiber (Polyester 65%, rayon 35%) equipped with UV cutting as well as water resistance etc. was recommended. In the uniform design process, the effective communication with user (postman) is critical to find the requirements and needs of uniform user (postman). Also. the uniform designer should reflect the above four key factors in design development. Therefore, the uniform should provide the user with high job performance and job pride in wearing the uniform.

With the change of times, the postal service environment and the customer's service needs are changing greatly. In this paper, we researched to improve inefficient service for registered mail by using ICT technology. ICT-based non-face-to-face smart mailbox system can deliver mail efficiently and improve customer satisfaction. In addition, it is expected that it will be able to reduce the work intensity of the mailman delivery of mail and greatly improve the working environment of the on-site deliverymen.

현재 우리나라의 일반 서장우편 물량은 매년 증가하고 있는 추세이며 특히 월말이나 연말에 집중화되는 계절적, 순환적 특성을 보인다. 그러나 집배원의 인력 부족으로, 우편물량의 증가와 계절적, 순환적 우편물 집중 현상에 적절히 대응하지 못하고 있으며, 이에 따라 서비스의 질적 저하 업무 부하량 증가 등의 문제가 점점 더 가시화되어가고 있다. 이러한 상황에서 신속한 우편물 처리와 집배원의 업무 경감 등을 위해 우편물 자동 처리를 위한 순로구분 시스템의 도입을 검토하고 있으나, 우편물에 기입되는 주소 기재 방식이 일관적이지 않고 표기 방식이 다양하여 이러한 자동처리시스템의 효율이 떨어질 것으로 예상된다. 따라서 본 논문에서는 향후 도입될 예정인 순로구분 시스템의 자동처리 효율을 높이기 위해 우편물에 기입하는 주소의 표기 표준화 방안을 제시하고자 한다. 이를 위해 우선 국내 우편주소 체계와 주소 표기의 현황을 살펴보았으며, 자동주소인식에 적합한 주소 표기를 위한 고려사항들을 주소 표기 표준화 관점에서 제시하였다.

This study evaluates the problems with various aspects of Korean mail carrier uniforms. It is sponsored by the as part of a 2002 research project. This research project is 'A study on mail collection and delivery environment based on ergonomics'. One of the most urgent tasks to create a better work environment is improvement of mail carrier uniforms. Improved uniforms will result in improved job performance and satisfaction.

The purpose of this paper is to devise an optimal route allocation algorithm for automated vehicle(AV) in monitoring quality of road infrastructure to support the road safety. The tasks of an AV in this paper include visiting node-links at least once during its operation and checking status of road infrastructure, and coming back to its depot.. In selecting optimal route, its priority goal is visiting the node-links with higher risks while reducing costs caused by operation. To deal with the problem, authors devised reward maximizing algorithm for AVs. To check its validity, the authors developed simple toy network that mimic node-link networks and assigned costs and rewards for each node-link. With the toy network, the reward maximizing algorithm worked well as it visited the node-link with higher risks earlier then chinese postman route algorithm (Eiselt, Gendreau, Laporte, 1995). For further research, the reward maximizing algorithm should be tested its validity in a more complex network that mimic the real-life.

우편물의 자동구분은 우편물을 OVIS(OCR-Video coding Integrated System)에 자동으로 공급하고 우편물의 수취인 주소영역을 카메라를 이용하여 획득한 다음 우편번호를 인식하여 바코드로 변환하여 인쇄하게 되고, 이 우편물은 LSM(Letter Sorting Machine)으로 보내져 BCR(Bar Code Reader)에 의해 인쇄된 바코드를 판독하여 행선지별로 구분하는 과정을 거친다. 주소의 번지 이하 부분은 배달원의 수작업에 의해 최종 배달지점 순서대로 정렬한 다음 배달하게 된다. 이 부분의 작업에 소요되는 시간은 배달원 일일 평균 4 시간에 달하며 원가절감 대상으로 지적되고 있다. 이 부분을 자동화하여 우편물 처리시간을 단축하고 생산성을 향상하는 방안이 대두되고 있으며, 이를 해결하기 위해 번지 부분까지 OCR을 이용, 인식하여 우편번호 및 순로 데이터 베이스에서 인식결과에 해당하는 코드를 추출하여 해당 구분 칸으로 우편물을 분류하는 방식을 택하면 집배원이 우편물을 배달하는 순로까지 자동으로 정렬할 수 있게 된다. 본 논문은 수취인 주소영역의 주소부분을 자동판독하기 위한 시스템을 개발한 내용을 다루고자 한다.

우편물 자동구분 처리의 범위를 확장시키기 위하여 집배원의 배달순서로 구분하기 위한 방법이 요구된다. 이는 우편 자동구분처리를 위하여 우편봉투에 인쇄된 주소 및 우편번호를 인식하고 이에 대응하는 자동구분정보를 우편물상에 바코드 인쇄하고 판독하여 구분하게 된다. 또한, 다량우편 이용자들에 의하여 우편물 상에 고객 바코드가 사전에 인쇄된 경우에는 바코드를 판독하여 구분한다. 본 논문에서는 우편물 자동구분 처리를 위하여 적용될 4-state 바코드에 정보수록 밀도를 향상시키기 위한 방법을 적용한 것이다. 시험 결과에 의하면, 4-state 바코드의 정보수록밀도는 기존의 16.67% 보다 약 27.79% 향상시킬 수 있었다.
