To comply with recent international trends and initiatives, and in order to help achieve sustainable development, Korea has established a greenhouse gas (GHG) emission reduction target of 37% (851 million tons) of the business as usual (BAU) rate by 2030. Regarding environmentally-oriented standards such as the IGCC (International Green Construction Code), there are also rising demands for the ...

Protein and nucleic acid electrophoresis is one of the most widely used tools in research. It is so commonplace in labs today that few people recall the origins of this ubiquitous tool. No other technique provides as much information about the purity of a sample and the sizes of its components as quickly and with as little effort and capital expense. Protein electrophoresis was first developed ...

This paper deals with the economic optimization of prestressed concrete precast pedestrian bridges typically used in public works construction. These bridges are made of a precast concrete beam that integrates an upper reinforced concrete slab for the pedestrian traffic. The beam has a U-shape cross-section. Typical span lengths range from 20 to 40 m and the width ranges from 3.00 to 6.00 m. Th...

Manajemen sumber daya manusia sangat mempengaruhi produktivitas (Bloom, N., & Van Reenen, J., 2011). Pengaruh tersebut dapat bersumber dari skill pekerja, attitudes, dan behavior (Katou, A.A., Budhwar, P., 2015). Penerapan manajemen merupakan satu kesatuan dalam menentukan strategi yang kompetitiv (Neal, A., West, M.A., Patterson, M.G., 2005). secara sistematis meningkatkan sebesar 3.27% to...

A half-precast concrete slab system (HPCSS) is reported to exhibit excellent structural performance when compared with traditional slab systems. However, there is a lack of extant research examining the construction issues of an HPCSS. Thus, in this study, we analyze the construction process and productivity of applying an HPCSS by using a simulation method with the data collected from an actua...
