다중혈관 관상동맥 환자에서 y-문합을 이용하여 양쪽 내흉동맥만을 사용한 우회술의 조기 성적

How has Japan become a major economic power, a world leader in the automotive and electronics industries? What is the secret of their success? The consensus has been that, though the Japanese are not particularly innovative, they are exceptionally skilful at imitation, at improving products that already exist. But now two leading Japanese business experts, Ikujiro Nonaka and Hiro Takeuchi, turn this conventional wisdom on its head: Japanese firms are successful, they contend, precisely because they are innovative, because they create new knowledge and use it to produce successful products and technologies. Examining case studies drawn from such firms as Honda, Canon, Matsushita, NEC, 3M, GE, and the U.S. Marines, this book reveals how Japanese companies translate tacit to explicit knowledge and use it to produce new processes, products, and services.

Biocomposites reinforced with natural fibers: 2000–2010

Recently, there has been a rapid growth in research and innovation in the natural fibre composite (NFC) area. Interest is warranted due to the advantages of these materials compared to others, such as synthetic fibre composites, including low environmental impact and low cost and support their potential across a wide range of applications. Much effort has gone into increasing their mechanical performance to extend the capabilities and applications of this group of materials. This review aims to provide an overview of the factors that affect the mechanical performance of NFCs and details achievements made with them.

A review of recent developments in natural fibre composites and their mechanical performance

This article describes the study of the feasibility of pretreatment effect on oil palm ash (OPA) with hydrochloric acid (HCl) before compounding with the natural rubber (NR) using a conventional two roll mill. Results revealed that metal elements such as calcium and magnesium had been reduced from the OPA particle after treated by HCl solution, meanwhile the surface tended to be rougher and provided bigger pores on the surface. Scorch and cure times for HCl-treated OPA were longer with higher tensile strength, tensile modulus and hardness as compared to the nontreated OPA-filled NR vulcanizates.

The effect of untreated and treated (chromium sulfate and sodium bicarbonate) kenaf (KNF) on the water uptake and morphological properties of linear low density polyethylene/poly(vinyl alcohol)/kenaf (LLDPE/PVOH/KNF) composites was studied. The composites were prepared by using an internal mixer (Haake Polydrive) at 150 °C and 50 rpm for 10 min. The results showed that the untreated composites tend to absorb greater amount of water compared to the treated composites. This shows that the chromium sulfate and sodium bicarbonate treatment on KNF had improved the interfacial adhesion between KNF and LLDPE/PVOH matrices. Consequently, the capability of water absorption by the treated composites was reduced. Scanning electron microscope (SEM) result shows that lesser traces of filler pull-out and better filler-matrix interfacial adhesion were observed in the tensile fractured surfaces of treated composites.

The growth performance of the companies is often understood as business success while knowledge is recognized as a valuable resource for companies to sustain competitiveness in today’s challenging business environment. The objective of this paper is to investigate the relationship between knowledge management and growth performance in the Malaysian construction industry. Questionnaires were sent to 500 respondents (large construction companies grade G7) via postal service. From 500 modelling using SmartPLS© software. The findings show a positive relationship between knowledge management and growth performance in the Malaysian construction industry. The results of this study are valuable in establishing a valid and reliable survey instrument for construction companies especially in Malaysia.

Knowledge Management and Growth Performance in Construction Industry

In present research work, the theoretical study of structural, optical and electronic structures of the Rutiles S n 1 − x T i x O 2 ( x = 0 . 25 , 0 . 5 , 0 . 75 ) in monoclinic phase has been performed. The structural study reveals the phase change from tetragonal to base centered monoclinic at 25% and 75% of Ti-concentration in S n O 2 . While at 50% concentration of Ti in S n O 2 , the material has primitive monoclinic crystal structure. The optical constants like absorption coefficient ( α ) , reflectivity (R), dielectric constant ( ϵ ) , conductivity ( σ ) , refractive index (n), extinction coefficient ( κ ) and energy-loss function (L) have been studied comprehensively. It is found that the absorption edge for the material decreases by increasing Ti-concentration in S n O 2 . The band gap of materials increases with the increase of Ti-concentrations in S n O 2 .

A comprehensive study of titanium-doped tin oxide rutile for structural and optical properties

The increasing use of information technology (IT) applications in construction companies requires process management for the realization of IT benefits. Studies on the management of IT benefits to maximize expected benefits, avoid or minimize problems and barriers, and ensure successful IT implementation and realization of IT benefits are lacking. This study aims to investigate the procedures for managing the realization of IT benefits in construction companies. Approximately 103 questionnaires were used. Some procedures for the management of the realization of IT benefits in terms of implementation strategies and evaluation techniques were determined. We found that construction companies do not use a formal standard procedure for managing the realization of IT benefits and lack clear implementation and evaluation strategies/techniques. This study contributes by drawing management attention to understand that IT benefits require management interference to be realized, thus highlighting the need to...
