Modelling of an Additive 3D-Printing Process Based on Design of Experiments Methodology

<p><strong>Purpose:</strong> The implementation of additive manufacturing (AM) or 3D-printer manufacturing for technical prototyping, preproduction series and short production series can bring benefits in terms of reducing cost and time to market in product development. These technologies are beginning to be applied in different industrial sectors and have a great possibility of development. As these technologies are still in development, there is a need to define the capacity of the 3D machines to establish minimum standards for producing high-quality parts.</p><p><strong>Methodology/Approach:</strong> The proposed methodology is based on a design of experiments (DOE) approach, which serves as a guide for engineers when it comes to executing any experimental study. The following steps were followed (Unzueta et al., 2019): Phase 1: define; Phase 2: measure; Phase 3: plan; Phase 4: execute experimentation; Phase 5: analyse the results; Phase 6: improve via confirmation experiments; Phases 7-8: control and standardise.</p><p><strong>Findings:</strong> The proposed methodology is based on a design of experiments (DOE) approach, which serves as a guide for engineers when it comes to executing any experimental study.

Prise en compte des capacités de prévision des crues dans les plans de gestion de crise – exemple du plan de gestion de crise inondation de l'hôpital d'Avignon

Le centre hospitalier d'Avignon est implanté dans le champ d'inondation de la Durance, dans une zone protégée contre les crues par une digue. Afin de garantir sa mise en sécurité en cas de crue majeure, l'hôpital a souhaité se doter d'un plan de gestion de crise inondation. Le SPC Grand Delta, en charge de la vigilance hydrologique, de la mesure des débits et de la prévision des crues sur la Durance, a été sollicité pour apporter sa contribution à l'élaboration de ce plan. Tout en respectant les contraintes de temps imposées par le fonctionnement de l'établissement, la prise en compte des capacités de mesure et de prévision sur ce cours d'eau ont conduit à la validation d'un plan phasé de mise en sûreté du centre hospitalier, en adoptant une montée en puissance reliée à la vigilance hydrologique et aux données de débits disponibles sur le site VIGICRUES. Le travail collaboratif entre les services de l'hôpital, le SPC Grand Delta et les autorités départementales a permis, grâce à la mise en commun des compétences et des problématiques, de bâtir un plan réaliste et efficace qui prenne en compte aussi bien les besoins du gestionnaire de crise, les capacités réelles de prévision su SPC que les incertitudes liées à la prévision des crues.

Implementasi Last Planner System Pada Proyek di Palembang (Studi Kasus Proyek Rusunami Jakabaring)

Saat ini sektor konstruksi mulai melakukan upaya untuk mengurangi waste sekaligus meningkatkan value dengan mengadopsi teori produksi pada industri manufaktur kepada industri konstruksi yang disebut lean construction (konstruksi ramping). Sistem pengendalian produksi (production control) dengan konsep konstruksi ramping merupakan salah satu sistem dalam perencanaan dan pengendalian jadwal pekerjaan. Komponen yang terdapat konsep konstruksi ramping tersebut adalah sistem the Last Planner (LPS). Last Planner System belum banyak digunakan dan mempunyai potensi yang baik karena merupakan bagian dari komponen lean construction dimana dalam perencanaannya semua pihak dapat terlibat secara langsung dan terkoordinasi sehingga pekerjaan yang direncanakan dapat terkontrol dengan baik dalam pelaksanaannya. Setelah melakukan analisis progress kerja harian, LPS mempunyai indikator kinerja yang digunakan untuk mengukur sejauh mana aliran pekerjaan dapat tercapai dengan baik, adapun kontrol aliran kerja Last Planner System yaitu Master Plan, Phase Planning dan Pull Planning, Lookahead Planning, Constraints Analysis, Shielding Production, Weekly Work Plan dan Percent Plan Complete (PPC) sebagai standar untuk mengontrol unit-unit produksi, menentukan jadwal proyek, strategi pelaksanaan, dan lain-lain. Pada penelitian ini, hasil rata-rata PPC adalah 73%. Tujuan dilakukannya penelitian dengan metode LPS ini yaitu untuk menganalisis implementasi konsep Last Planner System yang dibandingkan dengan progress aktual dalam meningkatkan reliabilitas pekerjaan harian dan Melakukan evaluasi kinerja pekerjaan kontraktor menggunakan LPS. Metodologi yang digunakan pada penelitian ini menggunakan kurva S, data progress rencana dan aktual mingguan proyek juga dilakukan pengolahan data dengan konsep aliran kerja LPS. Untuk membuktikan bahwa perhitungan PPC yang dilakukan sesuai dengan kondisi di lokasi proyek, maka dilakukan perbandingan data dari hasil perhitungan PPC menggunakan LPS dengan progress data mingguan di lokasi proyek yang didapat dari pihak kontraktor. Dari hasil perbandingan data tersebut dapat dilihat bahwa hasil PPC mingguan tidak jauh berbeda dengan hasil data progress mingguan yang didapat dari pihak kontraktor. Hal ini membuktikan bahwa LPS dapat meningkatkan reabilitas perencanaan di atas 70% sehingga tingkat resiko terjadinya keterlambatan proyek akan semakin kecil.

Practitioners’ multi-disciplinary perspectives of soccer talent according to phase of development and playing position

The study aimed to establish the perceived importance that academy soccer practitioners placed on technical/tactical, physical, psycho-social player attributes during player selection and explore whether perceptions change according to Elite Player Performance Plan phase. Seventy academy practitioners working within Elite Player Performance Plan programs (Category 1: n = 29; Category 2: n = 13 and Category 3: n = 28) completed an online survey. Psychological factors were rated significantly ( p ≤ 0.01) higher than sociological, technical/tactical, and physical factors, with recruitment staff specifically valuing psychological factors significantly ( p ≤ 0.01) more than medical staff. Youth Development phase practitioners valued sociological factors significantly ( p < 0.05) more than in the Foundation phase, which was also true for physical factors. Practitioners indicated significant positional differences for most physical and technical/tactical attributes. There was no playing position effect for relative age effect or maturity. Between playing position variance of outfield players for most technical and physical attributes increased according to advancing Elite Player Performance Plan phase. Attitudes to holistic talent identification criteria likely change according to practitioner role. Therefore, this study provides evidence to suggest that Elite Player Performance Plan practitioners place less perceived importance on enhanced maturity status and relative age of players but does indicate an enhancing and significant positional preference for physical and technical/tactical attributes. Suggesting that practitioners are less likely to (de)select players based on transient, maturity-related attributes and instead place greater emphasis on specialist physical/technical position-specific attributes as players navigate the Elite Player Performance Plan pathway towards professional status.

The Challenges Faced by the Model Teachers in Implementing Lesson Study

Previous studies have shown that the implementation of Lesson Study can give a good impact on both teachers and students. Lesson Study can help them binding up as a Learning Community in order to improve their self-development in teaching and learning. In addition, teachers and students prefer Lesson Study to be a sustainable activity in school. However, although Lesson Study has given a positive value on its practices, it does not mean that there are no challenges. The main purpose of this study is trying to reveal the challenges faced by the model teacher while implementing of Lesson Study practices. This study was a descriptive study, where the data were collected by interviewing 11 model teachers who teach in four different schools. The interview is given after conducting Lesson Study practices that cover three phases: PLAN, DO and SEE. The findings reveal that most of the model teachers faced challenges in PLAN phase and DO phase. In PLAN phase, model teachers stated that they find it difficult to develop Chapter Design because they did not understand well how to put their idea. They also find it difficult to adapt what they have written in Chapter Design and their activity when doing Open Class. In DO phase, most of model teachers stated that basically Lesson Study has a big impact in increasing their students’ understanding about learning materials, but the students were not active enough in the teaching and learning process. It means that the model teachers have to do a bigger effort to make their students more active in the classroom activities.
