The low foamed high strengthen styrofoam samples made by dielectric heating are discussed. We used the oscillator which have the frequency of 13.6MHz and the Power of 7kW. 3 times expanded beads by steaming method were used in our foam-molding test. Internal fusion properties and density of internal structure were improved by dielectric foaming process. At the temperature of 105-110$^{\circ}C$, the internal fusion property was maximally improved.

The purpose of this study is to investigate how the vendor suitability factor affects ERP introduction factors of domestic small and middle businesses and internal performance. When domestic firms introduce an ERP package, they mostly use the package already developed by ERP firms. Therefore, this study tried to analyze that the suitability factor of an ERP package supplier serves as a moderating role for ERP internal performance. The study result showed that the vendor suitability factor played a moderating role for ERP introduction factors and internal performance. In other words, the vendor suitability factor served a moderating role for four factors -CEO support, education/training, users' IT capability, and business standardization /formulation- and internal performance. But, it was analyzed that the vendor suitability factor didn't serve as a moderating role for IT infrastructure and internal performance.

In Korea, small and medium-sized enterprises (SMEs) play an pivotal role in the national economy, accounting for 99.9% of all enterprises, 87.9% of total employment, and 48.3% of production. In spite of their crucial role in the national development, most of SMEs suffer from a lack of R&D related resources. Public R&D organizations such as government-funded research institutes can provide SMEs with valuable supplementary technological knowledge and help them build technological capacity. In this regard, this study estimated the effect of internal R&D investment and private-public R&D cooperation on technological innovation of ICT SMEs based on 2016 ETRI Survey. Building on previous literatures, the study established and tested a research model using binary logistic regression analysis. First, internal R&D investment and preferences for open innovation demonstrated the strengthening of R&D collaboration. Second, internal R&D investment and R&D cooperation showed a positive effect on both product and process innovation. Therefore, internal R&D capability and taking advantage of R&D collaboration are needed to achieve technological innovation for SMEs in ICT sector. This study also discuss implications for encouraging private-public R&D cooperation.

Purpose - Korean agriculture is facing internal and external environmental changes and the need for secure stable outlets. Active participation and mutually beneficial cooperation between enterprises and agricultural is necessary for a win-win situation. This study investigates the case for distribution cooperation and a cooperative system. To respond to the diverse needs of consumers and market reclamation, there is a need to analyze and categorize distribution cooperation. Research design, data, and methodology - A literature study, relevant interviews with enterprises, and meetings with local government practices were conducted. A survey frame was derived through the participation of agricultural enterprises and distribution cooperation models were categorized identifying win-win cooperation and best practices. It was organized on the basis of six best practice examples of distribution cooperation between industry and agricultural sectors, divided into three types: opening distribution channels, exporting cooperation, and developing new products. Results - An innovation management system that can adapt to environmental changes and problems of agriculture is necessary. A company has to supply high-quality agricultural products reliably to meet the preferences of consumers by introducing products that promote domestic market differentiation. In addition, consumers are choosing a variety of products that may include not only high quality products but also local products and safe products. The main areas of cooperation are the direct provision of agrifood raw materials to consumers. Next, would be to help agricultural sectors distribute and pioneer international markets. The ideal step for distribution cooperation is the joint investment in new products by business and agriculture. Conclusions - Agriculture and win-win cooperation with enterprises is in an early stage of social contribution. To implement a distribution cooperation model between business and agricultural sectors, it is crucial to establish a structured support system including joint councils. Additional requirements include strengthening agricultural capacities, creating a legal basis for provision, and producing a win-win cooperation environment. The promotion of win-win cooperation and agricultural enterprises needs to exist in various forms in order to establish a different type of incentive system.

Scribing is cutting process to determine production amount and characteristic of LED chip. So it is an important process for fabrication of LED chip. Mechanical process and conventional scribing process with laser source has several problems such as thermal deformation, decreasing of material strength and limitation of cutting region. To solve these problems, internal laser scribing process that generates void in wafer and derives self-crack has been researched. However, studies of sapphire wafer cutting by internal laser scribing process for fabrication of LED chip are still insufficient. In this paper, cutting parameters were determined to apply internal laser scribing process for sapphire wafer for fabrication of LED chip. Then, foundation of cutting condition was established to set up internal laser scribing system through investigation of cutting characteristics by several experiments.

This study suggests that Korea - Russia economic cooperation, which has been sluggish in the meantime, should be revitalized as a small, medium sized business that can be practiced at the local level of both countries. Some large scales of national projects were difficult to realize due to some internal and external factors. Therefore, if Russia's Far East region of the complementary economic structure with the Korea's Gyeonggi Province of Korea could form the basis of cooperation by centering on SMEs, it further can be positive for promoting cooperation among South Korea, North Korea and Russia. The trilateral cooperation among two Koreas and Russia is necessary for the balance of political and economic powers in the East Asia. China's retaliation case regarding THAAD (Terminal High Altitude Area Defense) clearly showed that the greater the economic dependence on a particular country, the more threatening it could be. Therefore, it is important for the political and economic security to keep the balance by diversifying economic cooperation counterparts. As China's influence in the global economy grows, building value chains for mutual prosperity with various neighboring countries is gaining great importance. To this end, this paper examined Russia's Eurasian Strategy, New East Policy, and Far East Development Policy which were designed to seek the way to establish Russia's independent economic zone not absorbed by Europe and China.

In this study, a muffler for the super heavy machinery in the 70 ton class is developed. Developing process relies on experimental and rule of thumb approach. Various muffler internal structures consisting of partition plates, perforated and non-perforated through pipes, and absorbent are tried and compared for the transmission loss performance. Based on the experimental results, the best combination and locations of the internal acoustic components which affects the muffler performance are determined.
