Research Problem: 45-65% of all medical supplies in hospital are used in operating rooms. Medical supplies in operating rooms are difficult to manage in general because many of them are frequently used and come in a variety of types. Purpose: Our aim was to strive for user-friendliness and reduce the inventory through efficient management of medical supplies stocked in operating rooms. Medical Facility: Korea University, Ansan Hospital Quality Improvement Activity: On the last day of each month, we checked the inventory of medical supplies in all operating rooms by identifying the amount of medical supplies in each room, warehouse, and OCS, identified problems, and presented the ways to improve. Improvement Outcome: We increased the number of post-processing medical supply items by 8%, and reduced the inventory cost by 15% through improved management of medical supplies.

프로젝트 수행은 많은 결함을 내포하고 있다. 특히 유사한 분야의 프로젝트 수행 경험이 없다면 결함은 전체 시스템에 많은 영향을 주게 된다. 따라서 이와 같은 결함은 프로젝트의 성공 여부를 판단할 수 있는 중요한 요소가 된다. 결국 효율적인 위험관리는 문제에 쉽게 대처할 수 있게 해주며, 예상하지 못한 품질, 예산초과 및 일정 지연이 되지 않도록 해준다. 본 연구에서는 소프트웨어 개발 시, 프로세스의 신뢰성 향상을 위하여 체크포인트를 제시하고 이를 활용하여 전체 시스템의 신뢰성을 향상하고자 한다.

Procurement and lifting scheduling of modules and resources in modular construction, where modules that are manufactured from factory are delivered and assembled on site, is a crucial factor that determines the efficiency of the whole construction. However, previous studies have barely acknowledged the significance of resource procurement process and lifting of modules in modular construction. Therefore, this research aims to derive factors that are in need of improvement for successful implementation of procurement and lifting efficiency, and visualize them according to their importance and performance on improvement through IPA(Important Performance Analysis).

This study tries to find out the resonable improvement method of the export logistics system for fresh agriculture products. Export logistics system improvement of fresh agriculture products rationalized the export network covering the export and import of fresh agriculture products from producers to end customers and realized cost reduction and profit maximization. We are also operating our very own comprehensive logistics system that maximizes customer satisfaction. Supporting the entire logistics process starting from the collection, unloading, sorting, packaging, customs clearing, and information up to comprehensive logistics services, the export logistics system of fresh agriculture products realized a comprehensive transport system that uses 12 feet cool container. We have successfully reduced logistics costs through efficient operation in the export logistics system of fresh agriculture products.

Though a fully thermally coupled distillation column consumes less energy than an original column, it is not widely implemented in practice due to its operational difficulty. A new fully thermally coupled distillation column is proposed for the operability improvement, and its performance is investigated. The main improvement is the separation of a main column to give an upper and lower columns and the installation of an intermediate heat exchanger between them to regulate the fluctuation of product compositions. A proper manipulation of column pressure in the separated main columns made easy vapor flow without a compressor. The operability improvement is examined in a hexane process from the dynamic simulation using a commercial design software HYSYS. The simulation results indicate that the coupling among inputs and outputs is loosened to make easy manipulation of product compositions in the proposed distillation system.

In the modern age. Building is getting higher and larger according to owner and social demands. Now when we are facing the need of the cost down and the reduction of economic loss. In this paper, the characteristics of the present conditions of site management were investigated with the field survey. And The Purpose of this study is to suggest the rational plans of construction planning in site management. The method of site management. however depends on experience of a construction manager. in order to solve this situation, it is necessary to create a method of site management that is adequate for the condition of construction. By cultivating excellent sub contractors, we can expect precise construction with a few experts. improvement in qualify of construction from standardization, computerization of each process. And the expectancies of this paper are that it can be used as efficient data for improvement of system to systematize site management work in Korea.

This paper describes the contents about the efficient routing technique for improvement of transmission in Wireless Sensor Networks. Existing flat-based routing protocols have several problems like data overlap and implosion. Gossiping Algorithm in WSN is able to reduce the overhead and transmit packets through already set up the path but it takes place the data delivery and problem of worst-case. In this paper, we try to solve two problems that are data delivery and worst-case by selecting neighbor nodes using RSSI and number of linkage. The proposed model is available to real-mote and we confirmed the improvement of the performance against existing models.
