Over Time

Pada industri pakaian jadi pelayanan dan kepuasan buyer menjadi hal penting dalam menghadapi persaingan agar dapat terus tumbuh dan berkembang. Order produksi setiap tahun terdiri dari berbagai macam style yang akan berganti setelah selesai diproduksi. Perusahaan akan melakukan penetapan waktu yang harus dicapai dalam menyelesaikan satu order, sehingga dapat berpengaruh pada efisiensi waktu proses dikarenakan seringnya aktivitas change over. Change over merupakan pergantian aktivitas produksi disuatu lini produksi dari satu produk ke produk lainnya. Metoda yang akan digunakan untuk mengurangi change over time (COT) pada lini produksi yaitu menggunakan Quick Change Over (QCO). Tujuan mengurangi COT untuk mengefisiensikan waktu proses produksi walaupun tidak untuk menambah kapasitas produksi. Waktu yang dibutuhkan selama set up mesin dalam QCO menjadi faktor yang paling lama sehingga beberapa proses set up harus disederhanakan sesuai dengan prinsip lean manufacturing. Upaya mengurangi COT pada proses penjahitan yaitu dengan penerapan pemeliharaan mesin yang terjadwal, menempatkan operator sesuai dengan skill matrix dan mempersiapkan aksesoris ketika diperlukan bagian produksi. Hasil setelah penerapan metoda QCO untuk style yang repeat order menunjukan bahwa COT line A20 mengalami penurunan, walaupun belum memenuhi standar target yang ditetapkan oleh perusahaan. Penurunan COT ini akan berdampak pada peningkatan produktivitas dan efisiensi di line A20.

Protective Behaviours

This study assesses how knowledge about protective behaviours against sexual abuse changes among 6 to 7 year-olds 22 girls and boys, after implementing the programme “Grita muy fuerte" (Shout out loud). The program is developed over 5 weeks in sessions of 60 minutes per week. In order to determine the effect of it, an evaluation is carried out with pre-test and post-test measures included in the program itself. According to the results, on the one hand, all students improve their knowledge of protective behaviours against sexual abuse and, on the other hand, in terms of gender, girls have greater knowledge than boys. It is concluded that the programme is effective in increasing awareness of protective behaviours against sexual abuse and that it is therefore advisable to set up this type of experience as part of the schools' educational project.

Experiments with real photons have been performed for many years at the Mainz accelerator MAMI with different detectors. The upgraded MAMI C accelerator recently delivered electrons with an energy of 1604MeV. The A2 collaboration performs experiments with energy tagged polarised real photons produced via 'Bremsstrahlung'. Linear and circular photon polarisation is possible. In the years 2005/2006 the Crystal Ball detector with its unique detection capability for multi photon final states was set up in Mainz. The Crystal Ball at MAMI setup offers an excellent possibility to study decays of the η and η′ mesons. Due to the high intensity photon beam the apparatus can be seen as an η-factory. Recent results from the Crystal Ball experiment at MAMI are presented. In the future we plan to use a longitudinal and transverse polarised frozen spin target to investigate the spin polarisibilities of the nucleons.

  Core stability and the ability to balance have both a critical role in today’s modern soccer. Majority of injuries originated from the weakness and inefficient strength of core musculature and the kinetic chain. The purpose of our study was to investigate the effect of a three month proprioceptive training programme on core stability and the ability to balance. We hypothesized that both of the skills might improve by the end of the 12-week exercise program. We set up a group involving 15 players, who regularly participated in a weekly 40 minutes special proprioceptive training routine. The control group hasn’t attended any additional strengthening workout session. The youngsters executed a fitball balancing task, in a seated position, and the so-called Stork-test.  Before the 3-month exercise program, we implemented a pre-, at the end of the program a post-test. According to our results, we may conclude that we had measured a significant difference only in the Fitball-test when players executed the single leg balancing test (Stork-test), we haven’t observed any significant difference.

At Texas State University, a cafeteria-composting pilot program was established in which students source-separated their organic waste at one of the food courts while the program educated students on the value of organic waste and compost. Waste sorting bins were set up in a dining hall to direct students to sort trash into recyclables, compostables, and trash. Waste audit results demonstrated the value of the operation to the university in terms of savings in waste hauling expenditures, as well as showed the percent contamination, and percent waste diverted to the university's recycling and composting program. There was a significant difference between pre and post-test waste audits. The pilot site composting program resulted in a net loss of $3741.35 to the university during the first year, but was expected to produce a positive net return of $2585.11 in subsequent years. The pilot test showed the program was most successful when ongoing education at the dining hall occurred. Additionally, the student-run composting program resulted in hands-on training for students in producing a valuable horticultural commodity in an emerging waste management field. Results also indicated opportunities for further diversion such as the incorporation of compostable cups and utensils, as well as through expanding the operation to include more collection locations. With more collection sites and, therefore, more efficiency, the expanded composting program has the potential to become a self-supporting operation.

Várias abordagens têm surgido para incrementar o desempenho das operações. Entre elas, cabe citar a Lean Manufacturing, pelos resultados em produtividade, e a Quick Response Manufacturing (QRM), pelo tratamento de alta variedade. Porém, a literatura ainda não tem mostrado como utilizá-las em conjunto ou se podem ser complementares entre si. O objetivo neste artigo é encontrar as semelhanças, diferenças e complementaridades entre as duas abordagens. Para isso, realizou-se uma revisão de literatura, classificando as publicações de acordo com as suas abordagens e ferramentas utilizadas, principalmente. As diferenças encontradas destacam-se pela programação de produção, os seus indicadores. As semelhanças destacadas são estratégias em reduzir desperdícios, uso de agrupamento celular e redução de set-up. As abordagens são complementares no incremento de flexibilidade do QRM para o Lean, tanto nos produtos como na cadeia de suprimentos. Futuras pesquisas podem explorar uma combinação das duas em forma empírica.
