Objectives: The prevalence of work-related musculoskeletal symptoms (WMS) among Korean dairy farmers has not been investigated. The purpose of this study was to assess the prevalence of WMS and to evaluate the relationship between WMS and risk factors. Methods: Self-developed questionnaires including the questionnaire developed by the Korean Occupational Safety and Health agency (KOSHA) were used to investigate WMS among dairy farmers in Gyeonggi Province, Korea. We informed selected dairy farmers about the study and sent the questionnaires by registered mail. They visited a public health center nearby or a branch of public health center on the appointed date and skillful researchers identified or conducted the questionnaires by interview. We analyzed 598 (32.8%) of the 1824 dairy farmers. Multiple logistic regression was implemented to estimate the odds ratios of risk factors. Results: The mean age of the respondents was $50.4{\pm}8.7$ years and the proportion of males was 63.0%. The prevalence of WMS at any site was 33.3%. The prevalence of neck WMS was 2.2%, shoulders 10.0%, arms/elbows 5.0%, hands/wrists/fingers 4.2%, low back 11.5%, and legs/feet 11.7%. The adjusted odds ratio of low back WMS for milking 4 or more hours per day was 4.231 (95% Cl = 1.124 - 15.932) and statistically significant. Low back WMS (2.827, 95% Cl = 1.545 - 5.174) was significantly decreased by education. Conclusions: Low back WMS increased with milking hours and milking 4 or more hours per day was significantly associated with low back WMS. Low back WMS was significantly reduced with education. We hope that there will be increased attention about WMS in dairy farmers and the subject of future investigations.

Nowadays, a lot of enterprise completed the ERP implementation and these ERP-based enterprises consider the construction of WMS or already have done it. However the enterprises which Implemented WMS linked with ERP have many problems In the warehouse management and the reason ran be summarized In two poults First. In the integration point of view, only Interface issue between ERP and WMS was taken into account, therefore it was hard to reflect the phased process change. Second, a large number of WMS functions were tried to implement at the same tune and these attempts caused confusion and Instability which Is Interpreted as a main reason of the WMS failure. This paper presents the phased construction method for the successful implementation or WMS and in the integration point or view, the phased process change appears naturally

최근 GIS는 털러 분야에서 다양하게 운용되고 있다 최근에는 인터넷을 통한 정보 시스템의 요구가 급증하고 있으며, 웹 환경에서의 지리정보의 공유로 활용방안에 대한 연구가 활발히 이루어지고 있다. 특히, 지리정보의 활용을 위해 웹 지도 서비스의 요구가 증대되고 있다. 이를 위해 OGC(Open GIS Consortium)에서는 WMS(Web Map Service) 명세를 제시하고 있다. 그러나, 현재 제시되고 있는 WMS 명세만으로는 최근 발전하고 있는 모바일 환경에서의 적용이 어렵기 때문에 WMS의 인터페이스의 확장이 필요하다. WMS 확장을 위해 본 논문에서는 기존의 WMS를 분석하고 이를 바탕으로 모바일 환경에 적합한 WMS 확장 인터페이스의 방안을 제시한다. 또한, 확장 인터페이스를 바탕으로 모바일 환경을 위한 WMS 구조를 설계하고 개발한다. 본 논문에서 제안하는 WMS의 확장 인터페이스 및 이를 기반으로 하는 WMS 구조는 사용자들의 요구에 적합한 WMS 개발에 기초 자료로 사용될 것으로 기대된다.

현재 VoD 시스템은 마이크로소프트(Microsoft Corporation)에서 제공하는 WMS(Windows Media Server)를 사용하여 많이 구축하고 있다. 이 때 시스템의 QoS는 WMS의 성능에 크게 의존하기 때문에 WMS 의 성능을 동적으로 분석할 필요가 있다. 본 연구에서는 WMS 의 성능 분석을 위해 제안된 에이전트 시스템 모델(agent system model)에서 WMS와 인터페이스를 하는 에이전시(agency) 부분을 개발한다. 에이전시는 WMS가 클라이언트들에게 스트림 서비스를 제공하는 과정을 모니터링하고, 성능 분파에 필요한 데이터를 수집하여 저장하고, WMS 가 성능 향상을 위해 필요한 조치를 실행하게 한다.

It has been said that Warehouse Management System(WMS) in e-Trade has considerably contributed to improvement of distribution industry. However, in the aspect of management we have many technical problems such as transportation due to tremendous demands of online data. Therefore, for Korea to be a hub of distribution and information, this is the best time to prepare the foundation of Supply Chain Management(SCM) under Enterprise Resource Planning (ERP) the and make a good use of WMS. The purposes of this study are presented as follows: First, it is to examine the general flow process of WMS in each field of our e-Trade Second, it is to present problems and plans of improvements involved in WMS in e-Trade. In short, this study aims at presenting interpretative foundation of WMS in a practical viewpoint, not presenting technical directions of WMS.

Warehouse Management System was a helper of business in past, but it is perceived as a core competitive power and a tool for generating new business. It have been come out some new prospects for WMS due to generalization of global outsourcing and extension of the range of supply chain. In China, H automobile company construct the new WMS for providing the production extension and increment of part demand for A/S. This paper deals with the location management in warehouse, warehouse management, delivery management of goods from a warehouse, inventory management organizing WMS for construction of A/S warehouse in H motor in China. Then we identified the several problems of existing warehouse and constructed the driving organization and methods for overcoming these problems. We continually gather data for analysing the effects of new A/S warehouse and WMS construction.

It is very important to analyze the correlation between discharge and water quality. The observation of discharge and water quality are effective at same point as well as same time for real time management. But no less significant is the fact that there are some of real time water quality monitoring stations far from the T/M water stage. Pyeongchanggang station is one of them. In this case, it need to observe accurate discharge data, and to develop forecasting program or system using real time data. In this paper, discharge on Pyeongchanggang station was calculated by developed runoff neural network model, and compared with discharge using WMS(Watershed Modeling System) model. WMS shows better results when peak discharge is small and hydrograph is smooth. Forecasted discharge of neural network model have achieved the highest overall accuracy of specific discharge and WMS. Neural network model forecast change of discharge well on unrecored station.

Warehouse Management System (WMS) is a key control for Material Handling System (MHS) and Inventory Control System (ICS). How to design and implement for WMS is crucial factor for achieving the key performance index for Manufacturing Industry. In particular, iron and steel making industry, where the volume and weight is large and hence FIFO (First Input First Out) is not working, how to design WMS is a key factor. In this paper, we systematically define the problem of WMS via developing StR (Stakeholders' Requirements) or ORD (Operational Requirement Documents), SyR (System Requirement), and SA (System Architecture) based on the emerging technologies. In particular, IoT (Internet of Things), CPS (Cyber Physical System) concepts and enabling technologies haves been incorporated in developing Smart WMS. The deliverables of the research can provide a conceptual framework for developing the next generation industrial WMS.

This study presented practical directions for logistics network unification services, storage and shipment automation in order to prepare advanced strategies for warehouse management systems(WMS) of e-trade using network technology. The WMS technology using UPnP network will be a new paradigm in logistics and distribution. To meet desires of our society and develop successful unified logistics services, what is proposed in this study should be properly performed and it is important to have proper attitude to deal with new changes. Therefore, this study aims to present a base for interpretation of WMS using UPnP network rather than its technological directions.
