Super In Plane Switching (S-IPS) technology is applied for large TFT-LCD panels used in TV applications. It has a lot of advantages in comparison to the alternative, VA technology. S-IPS shows excellent viewing angle properties and fast response time between intermediate gray levels. If the performance parameters which describe the actual visual performance are considered, S-IPS is much more $advantageous.^{1)}$ However, it shows relatively low contrast ratio in diagonal direction compared to viewing angle characteristic in upper/down direction in S-IPS. In order to compensate the relatively low diagonal contrast ratio, Super-IPS applying for optical film developed, but Super-IPS still has the problem of color shift in black $pattern.^{2)}$ So we improved this problem by developing Enhanced Super-IPS.

본 연구에서는 기업의 외부 혁신 원천의 하나인 공급사와의 기술협력을 중심으로 기술협력의 선행요인들을 식별하고, 이들 선행요인들이 신제품 개발 성과에 실질적인 영향을 미치는지를 살펴보고자 한다. 분석을 위하여 2012년 산업통상부와 생산성본부가 함께 수행한 600개 제조업을 대상으로 한 MPS 패널 데이터를 사용하였다. 기술협력의 선행요인으로 신뢰, 통제 및 정보공유를 사용하였고 이들이 공급사와 구매사의 기술협력 성과에 미치는 영향을 회귀분석 하였다. 또한 신뢰, 통제 및 정보공유가 기술협력을 매개로 하여 신제품 성과에 영향을 주고 있는지에 관한 매개분석을 실시하였다. 분석결과 두 기업 간 신뢰, 통제 그리고 정보공유는 공급사-구매사의 기술협력 성과에 긍정적으로 작용하고 있으며 기술협력의 수준이 높을수록 신제품성과가 향상되는 것으로 나타났다. 선행요인 중 신뢰는 기술협력을 매개로하여 신제품 성과에도 긍정적으로 작용하는 것으로 나타났다. 본 결과는 기업이 다양한 외부 조직과의 혁신활동 수행에 있어 참여조직 간의 사회적 자산인 신뢰의 형성 및 관리가 개방형혁신 성공에 중요한 역할을 하고 있음을 시사한다.

The current manufacturers have generated tremendous amount of digitized product data to efficiently share and exchange it with other stakeholders or various software systems for product development. The digitized product data is a valuable asset for manufacturers, and has a potential to support high level strategic decision makings needed at many stages in product development. However, the lack of studies on extraction of key performance indicators(KPIs) from product data management(PDM) databases has prohibited manufacturers to use the product data to support the decision makings. Therefore this paper examines a possibility of an architecture that supports KPIs for evaluation of product development performances, by applying multidimensional product data model and on-line analytic processing(OLAP) to operational databases of product data management. To validate the architecture, the paper provides a prototype product data management system and OLAP applications that implement the multidimensional product data model and analytic processing.

Along with rapid global economic development, people are slowly becoming environmentally aware and green development is increasingly a vital topic of social concern. Academic circles are currently focusing on environmental protection and economic growth to explore the coordinated development of both and to achieve a win-win solution between them. To study the relationship between environmental protection experience and both cost and performance, this study empirically analyzes companies listing on the Shenzhen A-share market from 2014 to 2018. The results show that senior executives' environmental protection experience is negatively correlated with corporate costs, whereas it is positively correlated with business performance. These results provide empirical evidence of the importance of enterprises introducing and cultivating environmental personnel and insisting on sustainable development.

The EOTS(Electro Optical Tracking System) must have stabilization performance to provide high-quality images under disturbance environment. In this paper, we present a controller that can minimize the LOS error and has a simple structure. Hence, to evaluate the performance of this controller, analysis in the frequency domain and LOS error measurement are performed. In order to measure the LOS error without a 'rate table' that requires a lot of facility investment, we propose a design method for disturbance model that considers the operating environment of the EOTS. Finally, the performance of the stabilization algorithm is evaluated by the proposed disturbance model.

Indonesian construction companies are currently facing high competition both among themselves and with global construction companies. In order to address this issue, the Government of Indonesia has enacted specific regulations and policies relating to the development and implementation of quality management systems (QMSs) ISO 9001 based in construction, acknowledging that the consistency of construction project quality requires a formal quality system as a guarantee to raise quality standards at all project stages. The research has been undertaken to examine the effectiveness of the regulations and policies against several key performance indicators (KPIs) of the ISO 9001 Indonesian construction companies. A comprehensive review of the relevant regulations and policies together with interviews with the Government and National Construction Services Development Board recommend possible additional guidelines and supporting quality system, which intends to measure contractors' project output against defined standards as well as to assess their performance among other similar service providers. The outcomes of the research contribute to the development of the Indonesian own construction industry quality measurement and assessment system.

The goal of this study is simulation of optimal search pattern of ships based on performance surface which are reflected underwater environmental. The process is as follows. First, temporal and spatial environmental database are extracted in complex environment and input hull mounted SONAR system parameters. The environmental database and SONAR system parameters are substituted to SONAR equations, and calculate signal excess, detection probability, detection range. And then, the performance surface, which can be used to provide operational insight of SONAR detection performance, are pictorialized. Finally, optimal search pattern of ships are simulated using genetic algorithm based on performance surface. And then, we certify optimal search pattern in various ways.

In M&S, radar model is a software module to identify position data of simulation objects. In this paper, we propose a radar performance model for simulations of air defenses. The previous radar simulations are complicated and difficult to model and implement since radar systems in real world themselves require a lot of considerations and computation time. Moreover, the previous radar simulations completely depended on radar equations in academic fields; therefore, there are differences between data from radar equations and data from real world in mission level analyses. In order to solve these problems, we firstly define functionality of radar systems for air defense. Then, we design and implement the radar performance model that is a simple model and deals with being independent from the radar equations in engineering levels of M&S. With our radar performance model, we focus on analyses of missions in our missile model and being operated in measured data in real world in order to make sure of reliability of our mission analysis as much as it is possible. In this paper, we have conducted case studies, and we identified the practicality of our radar performance model.
