Research indicates that good front-end planning (FEP) results in the achievement of higher levels of project performance. By facilitating collaboration among stakeholders in diverse locations with the use of workflow-enabled processes, such pressures can be reduced, and the overall process and results of FEP can be improved. With these goals, a front-end planning tool (FEPT) has been developed as support for owners and major contractors who are engaged in front-end planning. This paper presents the new FEPT and describes how it has been used for construction megaprojects in the nuclear power, oil and gas, and mining industries. The paper begins with the definitions related to and an explanation of the general process for implementing and applying the FEPT and then describes and analyzes how the FEPT was applied in case study projects in order to test its validity. The results indicate that the FEPT increases the efficiency and effectiveness of front-end planning for the megaprojects studied and that it has the potential to produce similar results for other megaprojects.

기존의 LMS(Learning Management System)는 학습자의 의도와 무관하게 처음부터 끝까지 모든 교육 내용을 모두 학습하게 구성됨으로써 온라인 교육의 목표인 언제 어디서든 이라는 원칙이 구현되지 못하고 있다. 또한 학습자가 요구하는 내용으로 수정 및 보완이 용이하지 않고, 개발 시간이 느리고 비용이 많이 소요된다. 따라서 학습자 요구에 맞는 교육컨텐트를 개발하려면 LCMS(Learning Content Management System)기반으로 교육코스를 개발하는 저작도구가 필수적이다. 본 논문에서는 학습자 요구에 맞는 교육과정을 개발하고, 교육의 효율성을 극대화 시키는 방법으로 학습객체 단위로 CDT-L(Course Development Tool-Learning Content Management System)을 개발하고자 한다. 또한 다른 객체와의 관계등을 생성함으로써 학습자에게 꼭 필요한 정보를 찾을 수 있도록 해주어 이를 통해 학습자 중심의 학습을 가능케 한다. 학습자의 특성을 고려한 맞춤식 교육 코스 구성으로 앞으로는 자신이 원하는 과정을 선택하고 학습자에게 맞는 코스 강의로 강의가 이뤄지는 것을 가능하게 하기 위해 코스와 학습객체에 대한 메타데이터를 표준 문서인 SCORM 1.2에 기반하여 정의한다. 정보를 가지고 있는 학습객체를 선택하여 파일과 정보를 저장한 식별하기 위하여 검색을 한다. COT-L의 구현을 통해 컨텐트 재활용도를 높이면서 교육과정의 개발시간과 비용을 줄일 수 있다.

Response surface methodology (RSM) is a group of statistical modeling and optimization methods to improve the quality of design systematically in the quality engineering field. Its final goal is to identify the optimal setting of input variables optimizing a response. RSM is a kind of knowledge management tool since it studies a manufacturing or service process and extracts an important knowledge about it. In a real problem of RSM, it is a quite frequent situation that considers multiple responses simultaneously. To date, many approaches are proposed for solving (i.e., optimizing) a multi-response problem: process capability function approach, desirability function approach, loss function approach, and so on. The process capability function approach first estimates the mean and standard deviation models of each response. Then, it derives an individual process capability function for each response. The overall process capability function is obtained by aggregating the individual process capability function. The optimal setting is given by maximizing the overall process capability function. The existing process capability function methods usually use the arithmetic mean or geometric mean as an aggregation operator. However, these operators do not guarantee the Pareto optimality of their solution. Moreover, they may bring out an unacceptable result in terms of individual process capability function values. In this paper, we propose a maximin-based process capability function method which uses a maximin criterion as an aggregation operator. The proposed method is illustrated through a well-known multiresponse problem.

Project management and deployment has gone through a long journey from traditional and agile to continuous integration, continuous deployment and continuous monitoring. Software industry benefited with the latest buzzword in the development process, DevOps that not only escalates software productivity but at the same time enhances software quality. But the implementation and assessment of DevOps practices is expository as there are no guidelines to assess and improvise DevOps application in software industries. Hence, there was a need to develop a hybrid model to assist software practitioners in DevOps implementation. The intention behind this paper is to implement the already proposed DevOps hybrid model using suggested tool chains including Jenkins, Selenium, GitLab, Ansible and Nagios automation tools through Jenkins project management environment and plugins. To achieve this implementation objective, a java application is developed with a web-based graphical interface. Further, in this paper, different challenges and benefits of Jenkins implementation shall also be outlined. The paper also presents the effectiveness of DevOps based Model implementation in software organizations. The impact of considering other automation tools and models can also be considered as a part of further research.

The Inconel 718 alloy is a well-known super-heat-resistant alloy and a difficult-to-cut material. Inconel 718 with excellent corrosion and heat resistance is used in harsh environments. However, the heat generated is not released owing to excellent physical properties, making processes (e.g., adhesion and thermal fatigue) difficult. Tool condition monitoring in machining is significant in reducing manufacturing costs. The cutting tool is easily broken and worn because of the material properties of Inconel 718. Therefore, tool management is required to improve tool life and machinability. This study proposes a method of predicting the tool wear with non-contacting sensors (e.g., IR thermometer for measuring the cutting temperature and a microphone for measuring the sound pressure level in machining). The cutting temperature and sound pressure fluctuation according to the tool condition and cutting force are analyzed using experimental data. This experiment verifies the effectiveness of the non-contact measurement signals in tool condition monitoring.
