Controlling industrial vehicle operated by human in warehouse was not simple since the information transfer for controlling the vehicle was not easy. However, as the technology for the WMS (Warehouse Management System) has been advanced and the PDA (Perso
The purpose of this study was to investigate the effects of the secondary tasks such as sending text message (STM) and searching navigation (SN) on skin conductance level (SCL) and deviation of vehicle speed during driving. The participants included 30 he
Though many researchers have interested in the effects of creativity management on the business performance, few have researched the relationship between management execution systems for creativity management and the performance. This paper tried to ident
Under limited resources such as budgets and experts, it is essential to set promotion priorities for standardization work items on IPv6 (Internet Protocol version 6) multi-networking technologies. Opinions of domain experts are surveyed and analyzed utili
This paper considers a topological optimization of a network design with mean packet delay and node connectivity constraints. The objective is to find the topological layout of links, at minimal cost. This Problem is known to be NP-hard. To efficiently so
차세대 웹 기술로 각광 받고 있는 시맨틱 웹에서 웹 리소스는 온톨로지에 기술된 다양한 메타데이타에 의해 가용하게 되며 이러한 온톨로지를 대상으로 한 검색을 위해 SPARQL과 같은 여러 시맨틱 질의 언어가 제안되었다. 그러나 이러한 시맨틱 질의 언어를 사용자가 습득하였다 하더라도 올바른 정보를 찾기 위해서는 사용자가 온톨로지의 구조와 어휘를 잘 파악하고 있어야 한다는 어려움이 있다. 특히 사용자가 질의 언어의 문법과 복잡한 형식 논리이론에 익숙하더라도
Poisson model and Gamma-Poisson model are popularly used to analyze statistical behavior from defective data. The methods are based on binary criteria, that is, good or failure. However, manufacturing industries prefer polytomous criteria for classifying
기계가공은 절삭 부위의 냉각작용과 윤활작용을 위해 절삭유를 많이 소모한다. 절삭유는 염소계의 극압첨가제 등이 함유되어 있어 작업자들에게 유독할 뿐만 아니라 대기의 오염을 초래하여 청정생산을 저해하게 되므로 이런 전통적인 방법은 작업자의 직업병으로부터 보호와 환경보호를 위하여 새로운 가공방법으로 변경되어야만 한다. MQL기계가공 방법은 절삭유를 아주 소량 소모하므로 청정생산을 위한 대안으로 떠오르고 있지만 많은 작업자들이 이에 대한 기술적인 확신이 부족하
This study looks at a company which introduced SAP program, one type of ERP systems, and how the firm copes with the problems which happen in business process. The research tried to solve the problem by IDEAL method of process software improvement methodo
Using the known result of the expected busy period for a controllable M/G/1 queueing model operating under the triadic Max (N, T, D) policy, its upper and lower bounds are derived to approximate its corresponding actual value. Both bounds are represented
Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, build
In service science, it is critical to measure service satisfaction for innovating service processes, which is challenging for service sectors oriented to the usage of IT systems. For that purpose, in this study, a model based on the technology acceptance
The shock absorber base assembly is one of the parts in the shock absorber equipment that controls the vehicle movement. It absorbs the shock and vibration to guarantee riding stability and comfort. It demands strength, reliability and strict airtightness
This study was performed to design and develop an ergonomic equipment for strawberry sorting and packing in agricultural working environments. Potential risk of work related musculo-skeletal disorders associated with farm workers performing strawberry sor
