This study aims to examine the effects of integrated performance measurement on firm success of beverage businesses in Thailand. Integrated performance measurement, organizational commitment, organizational citizenship behavior, and firm success are the main variables of the study. In this study, all 653 beverage businesses from Department of Business Development, Ministry of Commerce, Thailand are the samples of the study. The data collection was provided during February - April, 2016. A mail survey procedure via questionnaire was used for data collection. 163 responses were received. Of the surveys completed and returned, 159 were usable. The structural equation model (SEM) is conducted to examine the effects of integrated performance measurement on organizational commitment, organizational citizenship behavior and firm success. The results show that integrated performance measurement positively influences organizational commitment, organizational citizenship behavior and firm success. Organizational commitment positively affects both organizational citizenship behavior and firm success while organizational citizenship behavior positively impacts firm success. In summary, integrated performance measurement as a strategic management accounting approach is a key determinant of firms' business outcome. Firms need to support their resources and capabilities in developing, implementing, utilizing, and maintaining integrated performance measurement. Potential discussion, conclusion, and suggestions and directions for future research are highlighted.

Bicycle fitting used to depend on empirical adherence of bicycle Peter and intuitive judgment by hand, but recent developments in industry and the Fourth Industrial Revolution have continuously developed other related tools that can be applied to bicycle fitting. Depending on these circumstances, bicycle fitting technology is also developing, and due to the difficulty of the technicians, there is a limit to popularizing. The Bicycle Integrated Fitting System has the need for this study to make these problems easy for anyone to operate by the system of manual. The purpose of this study is to examine the methods of physical sizing among the various stages of developing these systems. Accurate physical measurements can improve the efficiency of bicycle riding and minimize the injury of bicycle risers issued by incorrect fittings. Thus, in this study, physical measurement methods for bicycle fitting were derived by body region and applied to the post-measurement fitting as well as the location and method of measurement. It has prepared a basis for establishing a core database for physical measurement of development of integrated bicycle fitting system. Research was conducted to enhance understanding and utilization of users after system development and results were derived for the purpose of the study. Research was conducted to establish a database for the development of a bicycle integrated fitting system, and future research on bicycle fitting methods, application of the system, and hardware development should be carried out.

DTV 필드테스트를 위해서는 다양한 계측장비와 운용장비를 통한 매우 많은 측정항목의 측정이 필요하다. 따라서 한 지역을 측정하는데 많은 시간이 소요될 뿐 아니라 측정자의 숙련도에 따라 측정결과의 정확도와 신뢰도가 떨어질 수 있다. 또한, 매체에 따라서는 수 천 지점 이상의 측정을 하게 되는데 이들 측정결과에 대한 체계적인 관리가 절실하다 본 논문에서는 이러한 문제들을 해결하기 위해 다양한 계측장비와 운용장비를 체계적으로 관리하고, 측정절차를 일반화하며 측정결과 데이터를 데이터베이스화하여 측정결과를 용이하게 파악할 수 있는 통합 측정 시스템을 제안한다. 제안된 시스템은 DTV 뿐만 아니라 DMB, DAB 등의 다른 디지털 신호 측정에도 활용할 수 있으며, 실제로 KBS에서 실시한 DTV 필드테스트에 적용하여 기존의 수동측정 시스템보다 정확성과 시간의 효율성 면에서 우수함을 증명하였다.

Additional functional upgrades to the large-area compton camera (LACC) measurement device that can provide characteristics evaluation information (nuclear species and radioactivity) and two-dimensional or three-dimensional distribution imaging information of radioactive materials existing in surface or internal of concrete structures are required in terms of work stability and efficiency in order to apply to actual decommissioning sites such as nuclear power plants or medical cyclotron facilities by using this measurement device. To this purpose, the technology that allows radiation workers to intuitively and visually check the distribution of radioactive materials in advance by matching the two-dimensional distribution imaging information of radioactive materials obtained through the LACC measurement device and visual imaging of the measurement zone (10 m × 5 m) was developed. In addition, the separate system that can automatically adjust the position (height) in units of the measurement area size (0.7 m × 0.3 m × 0.8 m) of the LACC measurement device was developed and the integrated management system for characteristics evaluation information and two-dimensional or three-dimensional distribution imaging information obtained per unit of measurement for radioactive materials was developed. These functional upgrades related to LACC measurement device can improve work efficiency and safety when measuring radioactivity of concrete structures and enable the establishment of appropriate decommissioning strategies using radioactivity measurement information for decommissioning nuclear power plants or medical cyclotron facilities.

The on-line measurement of high-power IGBT collector current is important for the hierarchical control and short-circuit and overcurrent protection of its driver and the sensorless control of the converter. The conventional on-line measurement methods for IGBT collector current are not suitable for engineering measurement due to their large-size, high-cost, low-efficiency sensors, current transformers or dividers, etc. Based on the gate driver, this paper has proposed a current measuring circuit for IGBT collector current. The circuit is used to conduct non-intervention on-line measurement of IGBT collector current by detecting the voltage drop of the IGBT power emitter and the auxiliary emitter terminals. A theoretical analysis verifies the feasibility of this circuit. The circuit adopts an operational amplifier for impedance isolation to prevent the measuring circuit from affecting the dynamic performance of the IGBT. Due to using the scheme for integration first and amplification afterwards, the difficult problem of achieving high accuracy in the transient-state and on-state measurement of the voltage between the terminals of IGBT power emitter and the auxiliary emitter (u_Ee) has been solved. This is impossible for a conventional detector. On this basis, the adoption of a two-stage operational amplifier can better meet the requirements of high bandwidth measurement under the conditions of a small signal with a large gain. Finally, various experiments have been carried out under the conditions of several typical loads (resistance-inductance load, resistance load and inductance load), different IGBT junction temperatures, soft short-circuits and hard short-circuits for the on-line measurement of IGBT collector current. This is aided by the capacitor voltage which is the integration result of the voltage uEe. The results show that the proposed method of measuring IGBT collector current is feasible and effective.

In this study, a beam-coupling system is designed to improve the coupling efficiency of achip-integrated spectrometer when the waveguide is arranged in a linear and discrete manner. In the proposed system the beam is shaped to be anti-Gaussian, to deposit adequate energy in the edge waveguides. The beam is discretely coupled to the corresponding waveguide by a microlens array, to improve the coupling efficiency, and is compressed by a toroidal lens to match the linear discrete waveguides. Based on the findings of this study, the coupling efficiency of the spectrometer is shown to increase by a factor of 2.57. Accordingly, this study provides a reference basis for the improvement of the coupling efficiency of other similar spectrometers.
