Purpose: In this study, we suggest the systematic and comprehensive model to develop PI(Performance Indicators) of the organization or the process. Methods: The model is developed theoretically by using SIPOC(Supplier, Input, Process, Output, Customer) approach which is a tool to analyze the process and is compared with existing models to develop PI or KPI(key performance indicators); financial indicators, BSC, IPOO(input, process, output, outcome), traditional QCD (quality, cost, delivery), and IOS(input, output system). Results: The model provides more systematic method to develop PI and more comprehensive set of PI pools for all kinds of hierarchical levels of process than any other models to develop PI or KPI. Conclusion: This model will provide useful tools for the managers and the organizations who wish to develop PI.

Workflow Management System (WFMS) is a software system to support an efficient execution, control and management of complex business processes. Since traditional commercial systems mainly focus on automating processes, they don't have methods for enhancing the task performer's efficiency. In this paper, we propose a new method of executing business processes more efficiently in that a whole process is scheduled considering the degree of the participants' workload. The method allows managing the largest constraints among constituent resources of the process. We utilize DBR scheduling techniques to develop the method. We first consider the differences between workflow process models and DBR application models, and then develop the modified drum, buffer and rope. This leads us to develop WF-DBR (WorkFlow-DBR) that can control the proper size of the task performers' work list and arrival rate of process instances. Use of WF-DBR improves the efficiency of the whole process as well as the participants' working condition. We then carry out a set of simulation experiments and compare the effectiveness of our approach with that of scheduling techniques used in existing systems.

In order to develop VirtuAlmighty system, CPDM (construction project data management) and CPLM (construction project lifecycle management) model must be settled beforehand. Because most of information systems based on 3D-Design have its own database and business process. So, our team will develop collaboration management architecture of construction process for Decision Support based on PLM (Project Life-cycle Management). This architecture with business processes and Database can be used in process develop, process monitoring with many stakeholders of project, process change management, and so on.

This paper was developed and described core-process to implement low on resistance which was the most important characteristics of SJ (super junction) MOSFET. Firstly, using process-simulation, SJ MOSFET optimal structure was set and developed its process flow chart by repeated simulation. Following process flow, gate level process was performed. And source and drain level process was similar to genral planar MOSFET, so the process was the same as the general planar MOSFET. And then to develop deep trench process which was main process of the whole process, after finishing photo mask process, we developed deep trench process. We expected that developed process was necessary to develop SJ MOSFET for automobile semiconductor.

본 연구에서는 습식 방법으로 진행 되는 BGA 현상 공정에 있어 기존의 수평 장비를 대체하여 수직 장비를 개발하였다. 지그를 이용하여 기판을 수직 방향으로 고정한 후 습식 공정을 진행함으로써 기존 수평 장비의 단점인 롤러와 기판 표면 회로 패턴의 충돌로 인한 회로 패턴 손상 문제를 원천적으로 제거하고자 하였다. 개발된 수직 장비의 공정 특성을 수평 장비와 비교 평가 하기 위하여 유니포미터 측정, 회로 패턴 손상 평가 및 불량 평가의 실험을 수행하였다. 평가 결과 수직 장비의 유니포미티 특성은 수평 장비와 동일한 수준이며 중력 방향의 액흐름에 대한 공정 특성 영향은 미미한 것으로 확인 되었다. 또한, 수평 장비 대비 $3{\sim}4{\mu}m$ 더 미세한 회로 패턴에 대해여 손상 없이 공정을 진행 할 수 있음을 확인 할 수 있었다.

The school classroom is a common living place where students spend 7 to 14 hours a day to prepare for their careers. Therefore, if the ventilation of the classroom is not properly performed, it may lead to the deterioration of learning ability due to the unclear air. The concentration of carbon dioxide in the classroom is reported to be high, and the increase in carbon dioxide concentration has a negative effect on the learner's academic performance. In this context, the purpose of this study is to propose a methodology for intelligent and responsive window opening-closing operation process that can reduce the concentration of $CO_2$ in the classroom in order to build a support space that can create an effective teaching-learning environment for adolescents. The specific objectives are as follows. First of all, we define the concept of window opening-closing operation. Secondly, twe develop the operation process of window opening-closing. Thirdly, we develop an algorithm for real-time window opening and closing (process) (Window Opening-Closing Operation Process). Finally, we verify the intelligent responsive window opening-closing operation process through developing examples of window opening-closing operation process using the parametric design program. This study is a preliminary study to develop algorithms necessary for window opening-closing operation. Based on the first-order algorithm, We simulated window opening-closing operations according to a hypothetical scenario. As a result, This study can show that the window is open and close depending on the $CO_2$ concentration, but the $CO_2$ concentration in the room is higher than outdoors. Consequentially, we suggest that it is necessary to develop an algorithm to supplement these results because window is often not working when the temperature difference between indoor and outdoor in winter is large.

The purpose of this study was to develop a scientific inquiry model that makes scientific inquiry accessible to science teachers as well as students. To develop a scientific inquiry model, we investigated the research process demonstrated by ten scientists who were working at academic research institutions or industrial research institutions. We collected data through scientists' journal articles, lab meetings and seminars, and observation of their inquiry process. After we analyzed the scientists' inquiry strategies and processes of inquiry, we finally developed the Scientist's Methodology of Investigation Process model named SMIP. The SMIP model consists of four domains, 15 stages, and link questions, such as "if, why", and "how". The SMIP model stressed that inquiry process is a selective process rather than a linear or a circular process. Overall, these findings can have implication science educators in their attempt to design instruction to improve the scientific inquiry process.

In this paper, we study structural changes and performance gains in condition-based maintenance process redesign when mobile IoT technology is embedded into urban railway rolling stock. We first develop condition-based maintenance To-Be process model in accordance with the IoT deployment scheme. Secondly, we draw upon theoretical framework of redesign process analysis to develop performance evaluation method suitable to predictive maintenance shift from As-Is ordinary maintenance practice. Subsequently, To-Be process performance evaluations are conducted adopting both the quantitative and qualitative method for time, cost, and dependability dimensions. The results ascertain the considerable benefits captured through detection abnormality prior to actual rolling stock failure occurrence, and details of performance improvements and enhancement of standardization level is revealed. The procedures and results presented in this paper offers useful insights in the fields of IoT economic analysis, condition based maintenance, and business process redesign.

BGA 제조용 습식 현상 공정에 있어 기존의 수평 장비를 대체하여 수직 장비를 새로이 개발하였다. 수직 장비의 장점은 기판 표면의 소프트한 드라이필름 회로 패턴의 요철과 장비 구동부와의 직접적인 접촉을 배제함으로써 현상 공정 진행 중 회로 패턴의 손상을 최소화할 수 있다는 것이다. 본 연구에서는 개발된 수직 장비의 공정 특성을 최적화하기 위하여 다구찌 실험을 수행하였다. 수직 장비에 병렬로 동시 투입되는 2장의 기판에 대하여 공정 특성을 동일하게 하기 위해 적절한 잡음인자 및 제어가능인자를 선정하여 망소특성치 실험을 수행하였다. 실험 결과 현상 약품액의 온도 및 현상 스프레이에 노출되는 시간이 주요한 제어가능인자인 것으로 평가되었다. 최종적으로 회로 패턴의 손상 없이 현상 공정을 진행할 수 있는 최소 회로 선폭이 선형패턴의 경우 수평 장비 $13.8{\mu}m$ 대비 수직 장비는 $10.4{\mu}m$로, 닷 패턴의 경우 수평 장비 $22.1{\mu}m$ 대비 수직 장비는 $16.3{\mu}m$로 각각 향상된 결과를 얻을 수 있었다.

It is central to use a scale to measure a person's level of a construct in mathematics education research. This article explains a practical process through which a researcher rapidly can develop an instrument to measure the construct. The process includes research questioning, reviewing the literature, framing a background theory, treating the data, and reviewing the instrument. The statistical treatment of data includes normality analysis, item-total correlation analysis, reliability analysis, and factor analysis. A virtual example is given for better understanding of the process.
