SCM activities in a company are considered as total innovation through synchronizing supply and demand while maintaining appropriate inventory level and reducing the business operating costs. Until now, even several researches are carried out on the SCM performance of the companies which have introduced and been operating SCM, the research on the cost analysis for the inventory which occurs frequently on supply chain is still insufficient. Especially, for the electronics industry in which the product depreciation is sharp caused by the short product life cycle and the complexity of distribution channels, even the inventory related costs are a major factor in business management, since the current estimated criteria of inventory costs are limited to the interest and maintenance management costs, the criteria do not reflect the total influence of the product depreciation and lost opportunity cost which are related to the business management. Furthermore, even though the rapid price drops of the distributor inventory caused by the frequent new model launch can be covered by the product manufacturers, the scale of total costs related to the inventory has not been conceived because the price compensation is traditionally considered as a market costs. In this research, we analyzed the inventory characteristics of electronics industry in which the price depreciation happens frequently, newly defining the estimated criteria of the product total inventory cost which includes price depreciation from the product manufacturers' view. Finally we focus on the case study of a representative electronics company and verify the scale of the influence on management performance.

In this study, we analyze the automotive chip ecosystem that recently caused the global supply shortage, and attempt to derive policy implications for us from the conclusion. Automotive chips are critical parts that control various systems so that a vehicle can drive itself or operate with electricity. The current shortage in supply and demand for automotive chips is due to the inconsistency between supply and demand between automotive chip companies and car manufacturers. To promote the automotive chip industry, new investment incentives, tax cuts, and human resource training are needed.

Cooperative and integrative partnerships between buyers and suppliers are very important for effective operations. Such partnerships should be based on various information technologies developed in recent years. Therefore, we investigated the relationship among IT performance, IT infrastructure and supply chain performance in buyer-supplier linkage using exploratory examination. This analysis is based on survey results of buyer-supplier practitioners in Korean electronics industry. Specifically, we used factor analysis, correlation analysis, and regression analysis. Major findings are as follows. First. buyers' IT performance contributed to enhance their operational & financial performance, and satisfaction. Second, buyers' IT infrastructure improved their financial performance and satisfaction but showed mixed effects on operational performance. Third, suppliers' operational performance enhanced buyers' operational & financial performance, and satisfaction. Fourth, suppliers' IT performance strengthened their operational & financial performance, and satisfaction. Fifth, suppliers' IT infrastructure showed positive relationships with operational performance and satisfaction.

As the global semiconductor supply chain falters, major countries are pushing to increase their self-sufficiency in semiconductors. In accordance with these global changes, R&D cooperation is evolving in the semiconductor industry. Previously, as for the case of Interuniversity Microelectronics Center (IMEC) in Europe, many cooperation initiatives were established regardless of nationality for improving productivity through measures such as reducing the time and cost required for joint research. Recently, however, cooperation aimed at strengthening one's own industry has been prominent, such as that led by Taiwan Semiconductor Research Institute (TSRI) and the United States National Semiconductor Technology Center (NSTC). Hence, the Korean semiconductor industry also needs to respond. Internally, technology localization should be promoted by strengthening the foundation for domestic R&D cooperation, while externally, it should expand close cooperation with companies from countries leading the semiconductor industry, such as the United States, Europe, and Japan.

Information technology (IT) has been applied to various fields, and currently, IT devices and systems are used in very important areas, such as aviation, industry, and national defense. Such devices and systems are subject to various types of malicious attacks, which can be software or hardware based. Compared to software-based attacks, hardware-based attacks are known to be much more difficult to detect. A hardware Trojan horse is a representative example of hardware-based attacks. A hardware Trojan horse attack inserts a circuit into an IC chip. The inserted circuit performs malicious actions, such as causing a system malfunction or leaking important information. This has increased the potential for attack in the current supply chain environment, which is jointly developed by various companies. In this paper, we discuss the future direction of research by introducing attack cases, the characteristics of hardware Trojan horses, and countermeasure trends.

Considerable attention has been given to supply chains and their management in order to increase competitiveness in current ever-increasing business environments. The attention is due to the common belief that SCM contributes to reducing the redundancy between its supply chain entities and increasing profits correspondingly. However implementing SCM in actual industries involves a large number of difficulties unexpected before. In this paper, experiences in implementing SCM in a semiconductor manufacturing enterprise are discussed with some remarks on how process systems engineering can contribute to establishing SCM. It is hoped that the lessons of the specific enterprise can be of good help to others as well.

Small and medium sized enterprises' (SMEs) environmental performance and activities have been often of great concern toward sustainability as they have been playing a critically important role in the economic and industrial development. Among many initiatives to engage SMEs into the sustainability framework, Supply Chain Environmental Management (SCEM) of large companies has a great potential to persuade SMEs to adopt environmentally improved activities. This study investigated the relationship between SCEM approaches of large companies and environmental activities of SMEs in the Korean electronics industry. A postal questionnaire survey was used as a data collection method, and factor analysis and regression analysis were applied to analyse the collected data. The empirical findings suggested that SCEM approaches of large companies have positive impacts on environmental activities of SMEs. Among SCEM approaches, the collaborative approach was more effective than the arm's-length approach. Additionally, this study found positive impacts of trans-national SCEM approaches on SMEs' environmental activities.
