In this paper, we describe the design of a fusion labeling system which is controlled by the Wi-Fi signals. The Current labeling system which is used in the industry is designed to work independently on the production line not connected with internet network services. For such reasons, it is very inconvenient for the labeling system to transfer such labeling data of the production line to the server computer. We propose a labeling system connected to the Wi-Fi service being able to send real-time transmission of labeling data. This system can supply the labeling data of production line to the server computer in realtime and improve the production quality than the existing system.

Wind power is the most rapidly growing energy source in the world. Increased focus on climate changes and renewable energy is supporting the wind power industry in gaining momentum. Noksan wind cluster in Busan has been a major area in manufacturing the elementary parts of wind turbine. Despite growing recognition of the significance of Noksan, there has been only limited attention paid and in recent years. This paper reviews the literature of the current burning issues in wind turbine industries in the western countries. In addition, it describes the present state of Noksan wind power generation cluster and suggests the future plans to make it more effective complex.

Randomization of the run order within a block is a technique commonly employed by the experimenters of block designs to avoid biases in the estimates of the effects of interest. In practice, however the experimental responses are sometimes affected by the spatial or temporal position of the experimental units within a block. In such cases, it is preferable to use a systematic ordering of the treatments. It is often possible to find an ordering which will allow the estimation of treatment effects independently of any trend is known as a trend-free block designs. In many idustrial and agricultural experiments, treatments are applied to experimental units sequentially in time or space. This paper begins with a review of concepts and properties of trend-free designs. We, then devise algorithms to generate linear trend-free designs. We extend and modify the existing algorithm which is given by Bradley and Odeh(1988). Also, the algorithm which generate all possible linear trend-free designs in provided.

This study is designed to analyze the status of R&D investment and managerial performance related to the domestic manufacturing. To accomplish the purpose of the study, We have regression analyzed 6,054 companies based on the data of 'Business Activity Survey' disclosed by Statistics Korea. Result of the study are as follows. First, electronics, IT, and auto industry account for 25.6% of the country's manufacturing companies and take up 75.8% of the total R&D funding for the manufacturing industry. Second, R&D funding exercises positive influence on sales and the number of registered patents, which last exerts positive influence on sales.

In Korea, engineering education based on industry demand is highly emphasized; the survey of industry demand or company satisfaction is frequently conducted. Although engineering schools have often attempted and implemented the reform of engineering education, it was found that company satisfaction with college education was always low. In this context, this study aimed to find the cause of the low satisfaction. To this end, the social background for the active survey of industry demand and company satisfaction, and its progress were investigated. The findings of this study showed that the survey of industry demand in Korea has limitations in improving the quality of college education or developing its future demand, contrary to its intention. This industry demand based approach has its historical and social root in the Korea-specific model of the catching-up style industry development and technology innovation. Therefore, it is difficult to establish appropriate academy-industry relations and discover future vision based on this model. This study presents a new way to understand and develop the future-oriented industrial and social demand, not just arguing for the uselessness of the survey of industry demand in engineering education.

Recetly, Many industry have used unknown composition gases and no information gases. These gases were used increasing. As use increases, The more important software that can predict dispersion region and speed. It is very difficult to predict the dispersion of new gases. Because, it is predict from existing database. In this study, we propose to esimate dispersion region and speed of some gases, using a FLACS software and equivalent gas.

The visibility for signals in designs is required for their analysis and debug during the verification process. It could be achieved through the signal dumping for designs during the execution of HDL simulation. However, such signal dumping, in general, degrades the speed of simulation significantly, or can result in the number of simulation runs. In this paper, we have proposed an efficient and fast simulation method for dumping based on the design checkpoint, and shown its effectiveness by applying it to industrial SOC designs.

This paper presents new IT model, PIIS that integrates the safety control, construction, and operation managements in a conventional gas industry The systemic approach based on the PIIS model may reduce or increase the parameters as maximizing the safety, risk and crisis management, and increasing the cost-effective productivity The rapid synchronization and integration of the process using the PIIS model may produce more profits and satisfactions between customer and gas supplier. Thus, the PIIS model should quickly be introduced to gas industry at the beginning stage of engineering design and construction processes for maximizing production, effectiveness, and safety of the system from the exploration of a natural gas to a final consumption.

The purpose of this study was to examine the level of importance of service quality provided by restaurant when industry meal service recipients used the restaurant. Additionally, the purpose was to compare the level of satisfaction on the respective service qualities of company cafeteria and outside restaurant. The level of relative importance and satisfaction of service quality attributes are comparatively analyzed using the Important-Performance Analysis (IPA) of customers in order to provide basic information on the direction of marketing to efficiently operate company foodservice facilities. Restaurant service qualities were divided into the six factors of hygiene, convenience, food, environment, subsidiary services and food distribution process. The results revealed that the 'environment' of both company cafeteria and outside restaurant was needed to improve as quickly as possible. Additionally, it was found that the level of satisfaction was higher in the 'food' and 'environment' factors when using company cafeteria and outside restaurants, which would become an important attribute for the company foodservice recipients to use outside restaurants than using company cafeteria. Accordingly, it could be said that company cafeteria will need further control of the 'food' and 'environment' factors.

The purpose of this study is to identify and manage the problem of components discontinuity in the future based on the implementation of information systems to solve the problem of discontinuance of militaries parts, so as to solve the problem of discontinuance of components in the operation of the weapon systems and reduce excessive expenditure due to aging of the weapon system. The purpose is to prevent the discontinuance of components in the future by up-dating the production phenomena of parts manufactures periodically. Defense industries and R&D perood can expand users convenience by supporting selection of more efficient parts in weapon systems development and information of vast components information systems.
