  • In most statistical process control(SPC), control charts are used in which samples are taken and a suitable statistic is determined and plotted. In these control charts, control limits, ${\mu}{\pm}textsc{k{\sigma}}$, from which a decision is made are mostly ${\mu}{\pm}3{\sigma}$ and current literature in control charts are mainly concerned with detecting a shift in the mean. Therefore, when $\sigma$ is increased considerably after a long time, using control limits set at the first time causes a great deal of economic loss. In this paper the solutions to determine new control limits which maximizes the profit per unit produced and reduce $\sigma$ to economically optimal level for a certain cost when $\sigma$ is increased due to process deterioration are proposed. By applying new control limits, $\alpha$ error decreases considerably compared to apply initial control limits when $\sigma$ is increased due to process deterioration. Therefore, false alarm investigation cost drops down to the level of initial a error. And also this solution provides useful information regarding replacement of a process when the process is reviewed regularly.

  • A Clinical Pathway(CP) is standard process to way of treat diseases or injuries which is adapted to each hospital based on National Clinical Practice Guideline(CPG). Since CP is standard guideline for doctors and nurses working in a hospital, making and modifying CP is one of the most important administrational work for hospital and also rare work because once it is fixed, it's not changed whether there are new kind of disease discovered or new treatment is developed. However, in present, patient's waiting time during hospital residence process, is discussed as service competitive for patients. In this research, we utilize process mining tool to verify patients treatment process follows CP with EMR(Electronic Medical Record) in a sample hospital, and suggest modifcation point of CP through verification.

  • Ohmic contact process for the fabrication of GaAs integrated circuits is very important. Specific contact resistivities, assuming Rsm=Rs, were measured after the rapid and the conventional alloying process, respectively. The results show that the characteristics of ohmic contact through the rapid alloying process is much better (Apc=1.3~3.3x10**-7 \ulcorner-(m\ulcorner. This is probably due to intensive and compound energy densities during the rapid alloying process. New analysis method of TLM patterns viz. measurements of normlaized specific contact resistivities are proposed to reduce measurement errors that could occur when measuring the small contact end resistances. The adoption of rapid alloying process for the mass production of GaAs integrated circuits could greatly reduce the total processig time.

  • Preconstruction process in a lean project delivery system was studied in one large healthcare project working for a general contractor. Researchers joined a new lean delivery project for approximately six weeks and participated in preconstruction process including design coordination, management coordination, and target costing while concurrently interviewing other project participants and employees, recording activity in meetings, and otherwise observing the process. The preconstruction process in lean project delivery system, called integrated project design, showed many benefits such as brining expertise of downstream players (i.e., mechanical and electrical contractors) into the design phase. However, lack of leadership and lack of design-integrator blocked the successful application of a new concept of design process.

  • In order to manufacture high quality goods, the engineers who will design them has to have board technical experience as well as profound engineering knowledge. The engineers also be able to design and manufacture well development goods base on new advanced technology. Design process can be defined as transforming activity raw material into finished producted for human needs. The wealth of nation depend on its ability to retrieve natural resources and manufacture goods. Its ability, creation of goods, is most fundamental component of economic wealth of rich country. The rich countries have combine their own design knowledge with computer technology and create new effective design process. In this paper, one of the useful and practice design process created for railway industry is introduced. Base on the concept of this design process, the automatic wheelchair lifter design for railway vehicle is performed.

  • This paper introduces a new concept - on-line FE model, as applied to metal rolling. The new technology allows for completion of process simulation within a tiny fraction of a second without loss of high-level prediction accuracy inherent to FEM. The three steps of an on-line FE model design namely, process metamorphosis, mesh design, and process variable design, are described in detail. The procedure is demonstrated step by step through designing actual on-line models for the prediction of the dog-bone profile in edge rolling. The validity and prediction accuracy of the on-line FE models are analyzed and discussed.

  • Company A should maintain myriad conversion tools for the purpose of making a geometric compilation of navigation maps. Company A is already using complex compilation tools, which are tailored to geographical areas and various GPS models. However, due to frequent requirement and personnel changes, there is an endless challenge for perfect tool configuration and multiple map consolidation. To solve this problem, Company A launched a process automation project using Graphviz, which is an open source workflow graph visualization software. Before implementation, they had to document their current map compilation processes and then match it with the applicable conversion tool. For effective representation of process controls, a new graphical process notation is designed, i.e. Y Block diagram. The authors will compare Y Block diagram with other process notations and explain why Y Block diagram is more useful for tool based business processes such as digital map generation processes.

  • 본 연구의 목적은 1990년대 이후 경제, 정치, 사회문화, 도시 공간 및 환경 등 제 측면에서 전개되고 있는 대전의 새로운 도시화 과정을 경험적으로 확인하려는 것이다. 선진국의 경우 1980년대 이후 세계 경제 구조의 변화 속에서, 이른바 포드주의적 사회경제체제에서 탈포드주의적 사회경제체제로의 전환이 나타나고 있다. 이러한 변화는 선진국의 주요 대도시에 영향을 미쳐, 사회 부문별 및 도시 공간적 측면에서 새로운 도시화 과정이 전개되도록 했다. 본 연구는 우리나라의 대도시에서도 이러한 선진국 대도시들에서 경험하고 있는 새로운 도시화 과정이 나타나는지 여부를 파악하기 위해 대전을 사례로 고찰해 보고자 한다. 주요 연구 결과는 다음과 같다. 첫째, 경제적 측면에서 대전은 1990년대 이후 탈산업화와 경제의 서비스화가 진행되고 있지만, 아직도 기존 경제구조가 근본적으로 전환된 것은 아니며, 기존 산업 유형과 새로운 첨단산업 경제가 공존하고 있다. 둘째, 정치적 측면에서 대전에서는 지역 정당인 자민련의 독점 구조가 해소되고 있으며, 시민운동의 활성화가 두드러지게 나타나고 있다. 셋째, 도시 공간적 측면에서 원도심의 쇠퇴가 진행되는 반면, 둔산과 유성의 신도심 지역의 발전이 확연하게 나타나고 있다. 결론적으로 대전에서 새로운 도시화의 단서들이 나타나고 있지만, 서구의 대도시들에서 나타나는 현상보다 훨씬 약하며 다소 상이한 모습을 보이고 있다.

  • Two new species of poecilostomatoid copepods associated with echiurans are described from an intertidal mud flat in the Yellow Sea. A new genus Echiuricopus is created to accommodate two new species, E. aprilis and E. tenuipes. Major differences between the two new species are displayed in body length, length of caudal ramus seta I, length/width ratio of leg 5 exopod, and armature of the first antennular segment. Echiuricopus n. gen. is closely related to the genus Goidelia Embleton, 1901, but is distinguished from the latter chiefly by having seven caudal setae, a claw-like process on the first antennular segment, one claw-like process on the maxillary syncoxa, the absence of an inner coxal seta on legs 1-4, different armatures on legs 1-4, and an elongate leg 5 exopod.
