  • This study was aimed to propose a safety management scheme for industrial accident prevention, which has been increasingly embossed by industrialists and authorities concerned. A particular attention has been paid to the integrated ideas and practices to be needed in the field supervision. For this, a primary perspective of the study was drawn from the significant analysis of the current industrial accidents. From this observation, the researcher assumed that the integrated scheme should be an extension to the scientific approach in order to overcome various industrial accidents. The researcher also tried to provide more detailed information in each divisions. i.e., an essential safety device, an occupational disease, an educational practice. In this paper, the researcher will show in a first step how industrial accident prevention can contribute to progress of industrial peace and safety. Finally, the researcher emphasized that more investments would be highly profitable to industrial accident prevention and we should be in realization that all of activities in safety management are to be the main key in labour-management cooperation.

  • According to "structure-conduct-performance" paradigm in IO, market structure (concentration) determines conduct (R&D investments), and conduct yields market performance (ratio of price to marginal cost). Previous empirical studies on Schumpeter Mark I, II assumed that the explanatory variable (market structure) and the disturbance are uncorrelated in the R&D equation. In this situation, Ordinary Least Squares (OLS) estimates of the structural parameters are inconsistent, because the endogeneous variables (R&D and market structure) can be determined simultaneously. So, in this study, full information (or system methods) estimation is used to test Schumpeter hypothesis since joint estimation can as well bring efficiency gains in the seemingly uncorrelated regressions (SUR) setting.

  • Explainable AI (XAI) is an approach that leverages artificial intelligence to support human decision-making. Recently, governments of several countries including Korea are attempting objective evidence-based analyses of R&D investments with returns by analyzing quantitative data. Over the past decade, governments have invested in relevant researches, allowing government officials to gain insights to help them evaluate past performances and discuss future policy directions. Compared to the size that has not been used yet, the utilization of the text information (accumulated in national DBs) so far is low level. The current study utilizes a text mining strategy for monitoring innovations along with a case study of smart-farms in the Honam region.

  • Purpose: Once the decision has been made to adopt an integrated medical information system (IMIS), there are a number of issues to overcome. Users need to be aware of the impact the change will make on end users and be prepared to address issues that arise before they become problems. The purpose of this study is to investigate the benefits and unexpected problems encountered in the implementation of IMIS and to determine a useful framework for IMIS. Materials and Methods: The Yonsei University Dental Hospital is steadily constructing an IMIS. The vendor's PACS software, Piview STAR, supports transactions between workstations that are approved to integrating the healthcare enterprise (IHE) with security function. It is necessary to develop an excellent framework that is good for the patient, healthcare provider and information system vendors, in an expert, efficient, and cost-effective manner. Results : The problems encountered with IMIS implementation were high initial investments, delay of EMR enforcement, underdevelopment of digital radiographic appliances and software and insufficient educational training for users. Conclusions: The clinical environments of dental IMIS is some different from the medical situation. The best way to overcome these differences is to establish a gold standard of dental IMIS integration, which estimates the cost payback. The IHE and its technical framework are good for the patient, the health care provider and all information systems vendors.

  • There are many recent monitor manufacturing firms not equipped with automatic checking system in their final process. And the check is based on the human perception, so the automatic checking system is needed for the consistency and the accuracy of the checking process to elevate the productivity and the quality. As the performance of computer systems and the vision systems has been increased, the cost for the system is reduced and their applicable algorithms have been developed. In this study we develop monitor checking system which is low-cost, fast, and easy to adopt by the small-scaled manufacturing films. The system is based on the computer vision techniques, and is equipped with the GUI interface and checking functions such as centering, yoke rotation, pincushion, sizing, brightness, and grayscale tracking. Monitor checking system developed in this study can be used in the final checking process thereby we expect the synergy effects both on the efficiency of production and on the reduction of the cost for the facility investments.

  • In quay processes in shipyards, it is difficult to manage workers and to maintain secure working environments because at least 1,000 people can occupy the quay at the same time. In this study, a system was designed to monitor the environment and processes of quay operation. In order to lower initial investments and the costs of maintenance and operation, the entire system consists of six connected components. Considering the communication environment of the shipyard site, Wi-Fi and the LoRa communication protocol were selected for the system. The feasibility of the communication protocols was verified by data transmission tests in the field. The designed system can provide real-time information about employees working in the quay area, the safety status of moored ships on the quay, and step-by-step alarms in dangerous situations based on the detected information. The system is expected to prevent or greatly reduce safety hazards.

  • Recently, interest in smart factories is increasing. Investments to improve intelligence/automation are also being made continuously in manufacturing plants. Facility automation based on sensor data collection is now essential. In addition, we are operating our factories based on data generated in all areas of production, including production management, facility operation, and quality management, and an integrated standard information system. When producing LCD polarizer products, it is most important to link trace information between data generated by individual production processes. All systems involved in production must ensure that there is no data loss and data integrity is ensured. The large-capacity data collected from individual systems is composed of key values linked to each other. A real-time quality analysis processing system based on connected integrated system data is required. In this study, large-capacity data collection, storage, integration and loss prevention methods were presented for optimization of LCD polarizer production. The identification Risk model of inspection products can be added, and the applicable product model is designed to be continuously expanded. A quality inspection and analysis system that maximizes the yield rate was designed by using the final inspection image of the product using big data technology. In the case of products that are predefined as analysable products, it is designed to be verified with the big data knn analysis model, and individual analysis results are continuously applied to the actual production site to operate in a virtuous cycle structure. Production Optimization was performed by applying it to the currently produced LCD polarizer production line.

  • The cost/benefit analysis method is frequently used in the feasibility study of investments on geo-spatial information system. The cost/benefit analysis method has been applied extensively in the feasibility study of conventional information systems and recently efforts has been made to apply this method to geo-spatial information systems as well. This study efforts were made to present a cost/benefit model suitable for Korean GSIS and this model was then applied to Facility Management. In establishment of the cost model, the items of various costs were defined and a survey was made to find the average unit cost of each item. For the benefit model, the benefits of implementing a geo-spatial information system is classified into tangible and intangible benefits and only th tangible benefits were further classified. The established cost/benefit model was then applied to a gas distribution company with more than 100 employees and more than 300,000 customers. A GSIS was designed and the cost its implementation was compared to the present manual method of operation.

  • Increasing number of transactions and investments in technology has sparked a growing interest in technology valuation. However, it has not been easy to come up with an objective valuation of technology due to variance in technology value and specialty of technology valuation. The main objective of this paper lies in the development of a new system for technology valuation, Web-based Interactive Technology Valuation (WITV) system, which valuate the technology and analyze the technology value strategy. WITV system uses the Technology Valuation Attractiveness Model (TVAM). TVA is composed of the Intrinsic Value of Technology (IVT) and the Extrinsic Value of Technology (EVT). This paper experiment the feasibility of the TVA Model and WITV System by conducting an empirical study on small & medium sized manufacturing companies in IT industry, registered on KOSDAQ. In this study, the potential value is defined as the technology value. It is represents the expected profit appraised by the market under the competitiveness of technology and the growth of the market. TVA is measured as the index to forecast the Price-to-Book value Ratio (PBR), which is the proxy variable for the potential value of the technology. The results identify the feasibility of the TVAM through a high correlation between the TVA and the PBR.

  • The commercial arbitration is considered an effective and rapid means in solving problems and finding solutions for disputes between the business partners. For the development of commercial arbitration, there is a need to study arbitration in practice as well as in theory. This paper analyse the situation of commercial arbitration system in Pakistan both with respect to domestic laws and international laws applicable in Pakistan. The Arbitration Bill 2009 aims to consolidate law relating domestic arbitration, international commercial arbitration, recognition and enforcement of foreign arbitral awards as well as settlement of international investment disputes. Pakistan while defending investment claims and in order to restore investor's confidence, in 2011, Pakistan introduced a law to secure foreign investments. This study explains the relationship of old and new Pakistani arbitration laws and elaborates the changes brought about by the new enactments and gives a comprehensive analysis of Pakistani arbitration laws, rules and procedures dealing with arbitration agreements and awards. In the absence of relevant trade information in Pakistan, this paper is designed to meet the needs of a Korean international trade scholars to obtain an understanding of Pakistani commercial arbitration system quickly.
