  • Currently, the world is facing severe inflation due to Corona and the war in Ukraine, and it is causing a lot of difficulties for us. Companies are facing a lot of restrictions on their economic activities compared to the past due to supply chain problems and foreign exchange rates. In this situation, many countries have been implementing various smart factory promotion projects to secure competitiveness through productivity improvement in the manufacturing industry. In this study, the contents of smart factory promotion in major countries were reviewed, and problems raised about the implementation of smart factory in Korea, which are being implemented based on this, were described. It is most reasonable to judge the success of a smart factory by the achievement of the performance indicators presented at the time of the project. Therefore, based on the performance index of the business, which is a key factor in determining the success or failure of a smart factory, we investigated whether the company's smart factory promotion can be carried out successfully through examples

  • This paper employs datasets from the Enterprise Survey conducted by the World Bank to examine the relationship between four types of innovation defined by the Oslo Manual (OECD, 2005): product innovation, process innovation, marketing innovation, organization innovation, and the firm performance in the selected developing ASEAN economies. The main objective of this paper is to understand the characteristics of innovation activities at the firm level and how various innovation types affect firm performance. The empirical results from ASEAN manufacturing firms reveal that product innovation positively affects firms' performance, while non-technological innovations are negatively related to the performance of firms. The further employed quantile regression provides more insights into the roles of innovation types on different levels of firm performance: while product and process innovations actively contribute to the small and medium-size firms (below 25th quantile and median), organizational and marketing innovations negatively affect them. Interestingly, the role of process innovation decreases when firm performance grows.

  • Nowadays, automobile manufacturers are faced with increasing global competition which is required low cost as well as high quality. To reduce shipping and handling cost and delivery time, lots of automobile manufactures tried to build their new factory in the neighborhood of market. Simultaneously, many factories are under construction in developing countries to make efficient use of low-wage workers. However, because systems are installed in developing countries as the same type of domestic facilities, systems have lots of problems such as high installation cost and inefficient use of manpower. To find core problems and generate optimal solution of these problems, thinking process of TOC(Theory Of Constrains) is used. In case of transmission gear machining system, semi-auto system is proposed as the best solution to increase manpower efficiency and system utilization. Semi-auto system consists of automatic machining process and manual transporting process. The system layout is generated based on semi-auto process concept. And, 3D simulation method using QUEST is used to verify production volume of generated system.

  • Purpose - This study attempted to discover the impact of the Korea-China FTA(Free Trade Agreement) on electronic products distribution industry. Strategies will be provided to expand both countries' trade after the Korea-China FTA. Research design, data, and methodology - This study analyzed the differences before and after the Korea-China FTA, using an RCA(Revealed Comparative Advantage) index, TC(Technology Sophistication Index) index and TSI(Trade Specialization Index) that considered the FTA tariff situation. Data was collected from the International Trade Statistics Database and Korea, China Customs Service. Results - The results indicate that following the Korea-China FTA, China and Korea's bilateral trade of electronic products is expected to expand, and both countries will experience net welfare gains from the markets' expansion. Korea is competitive in several key products, although it faces competition from China. China's electronic products' competitiveness have indicated an increasing trend. Conclusions - The two countries should closely cooperate and communicate with each other. Ultimately, Korea should focus on high-tech, sophisticated techniques to gain market advantage. On the other hand, with the tariff decrease as well as the labor cost and labor force base, China will greatly be able to benefit from the manufacturing of medium- to low-end products in the future.

  • Obesity is a global pandemic that is increasing throughout most of the world. Increases in obesity are not restricted to highly industrialized countries, but have been observed in newly developed and developing countries as well. Obesity is associated with increased risk for non-insulin dependent diabetes mellitus, coronary artery disease, and some types of cancer. Tragically, eliminating food shortages in developing countries may result in substituting heart disease, diabetes, and cancer for malnutrition. There are many approaches to reducing obesity, including dietary modification, surgical interventions, and drug therapies. However, only dietary modification has the potential to be effective on a global scale. Public health measures in the United States have sought to reduce obesity by reducing the intake of dietary fat. While these efforts have succeeded in reducing dietary fat, obesity has continued to increase, suggesting that moderate fat reduction may not be effective. Other proposed diets include low-carbohydrate diets, low glycemic index diets, and very low fat diets. While all of these diets may be effective for some people, they are not satisfactory for public health policy. In fact, the ratio of fat to carbohydrate may not be as important as previously believed. Humans may be well suited to adapt to diets as varied as a high carbohydrate tropical diet consisting mostly of fruits to the high fat Eskimo diet consisting largely of animal foods. Either extreme may be healthful if providing adequate, but not excessive, energy and adequate amounts of micronutrients. Public health measures may need to focuss on reducing the overconsumption of inexpensive and convenient foods.

  • This study examines performances and varieties of export of IP sensitive products across emerging countries, namely, India and China by utilizing 6-digit disaggregated product-level export data. Further, this study constructs trade margins - extensive and intensive margins to understand trade potential and different trade patterns, specifically, exporters' productivity, product diversification, and volume of trade during 2007-2016. This study finds India's performance is comparable with China at the extensive margin though the gap between India and China is very wide in terms of the total value of exports and the intensive margin. China majorly exports more expensive electronics and manufacturing-related products as opposed to relatively cheaper medicinal and synthetic products, the total value of exports from China to the rest of the world is much higher than that of India. This study suggests that India is exporting IP-sensitive products to lower-income countries sufficiently, but the IP-sensitive exports to higher-income countries are still lagging.
