  • Objective: The Korean Industrial Hygiene Association(KIHA) held a forum on "Improvement of Material Safety Data Sheets (MSDS) regulations for enhancing the effectiveness and efficiency in the field" at its 2018 Winter Conference(February 2, 2018). This article summarized the major consensus opinions developed at the forum. Methods: Since the initial implementation of the MSDS system, the contents of the system have changed and related studies have been reviewed. Before the forum, online questionnaires were developed and opinions on the effectiveness of MSDS program were collected from various strata of the occupational health field. We also summarized the key opinions of companies, trade unions, experts, and government officials as discussed at the forums. Results: A total of 265 opinions were gathered through online questionnaire surveys from safety and health managers, trade unions, government officials, and health professionals. The results of online surveys and discussions showed some differences of opinion, but it was a common perception that the current MSDS system is not working effectively in the workplace. It was considered necessary to strengthen MSDS education and to make it easier for workers to understand and deliver the necessary information. In addition, it was confirmed that the supply of and education on MSDS to small- and medium-sized enterprise workers is not being well executed. In particular, MSDS training for subcontract workers should be carried out under the responsibility of the contracting employer. Conclusions: In order for the MSDS system to serve more effectively in the field in the future, it needs to be improved in terms of the effective education and training considering the type of industry and employment.

  • 요즘 암호시스템을 효율적으로 수행하는 하드웨어의 개발이 관심의 대상이 되고 있다. 암호시스템의 효율적인 수행은 연산기의 효율적인 연산이 뒷받침되어야 한다. 특히 유한체 GF(2$^n$)에서의 곱셈기는 여러 연산 중에서 효율성이 고려되어야 할 핵심적인 연산이다. 이 논문에서는 유한체에서의 곱셈기를 시간 복잡도(time complexity)와 하드웨어복잡도(size complexity) 사이의 교환(trade-off)을 고려하여 기존 곱셈기$^{[5][12]}$의 하드웨어 복잡도인 #AND(AND gate 수)= $n^2$, #XOR(XOR gate 수) = $n^2$-1 보다 개선된 #AND = [n/2], #XOR = n([n/2+1])-$\delta$$_{n}$ (n이 짝수이면$\delta$$_{n}$ =1, n이 홀수이면 $\delta$n=0)이고 두 클럭 내에 결과를 얻을 수 있는 직렬-병렬 곱셈기를 제안한다. 우리는 기존의 논문에서 제안된 곱셈기와 구조를 달리하여 공간의 제약이 있는 하드웨어에 적합한 효율적인 연산기의 구현방안을 제시한다.

  • With the recent increase in international trade volume the trade volume through ships is also continuously increasing. The treatment of ballast water goes through the following five steps, samples are taken and analyzed at each step, and samples are obtained using a suction pump. These suction pumps have low efficiency and thus need to be improved. In this study, it is to optimize the form of the impeller which affects directly improvements of performance to determine the capacity of suction pump and to fulfill the purpose of this research. To do it, we have carried out parametric design as an input variable, geometric form for the impeller. By conducting the flow analysis for the optimum form, it has confirmed the value of improved results and achieved the purpose to study in this paper. It has selected the necessary parameter for optimizing the form of the pump impeller and analyzed the property using experiment design. And it can reduce the factor of parameter for local optimization from findings to analyze the property of form parameter. To perform MOGA(Multi-Objective Genetic Algorithm) it has generated response surface using parameters for local optimization and conducts the optimization using multi-objective genetic algorithm. with created experiment cases, it has performed the computational fluid dynamics with model applying the optimized impeller form and checked that the capacity of the pump was improved. It could verify the validity concerning the improvement of pump efficiency, via optimization of pump impeller form which is suggested in this study.

  • Purpose - The competitiveness of logistics in the 21st century rests on ensuring the efficiency and effectiveness of its local hub. While considering entry into a niche market in local logistics, it is pertinent to note that Budapest is emerging as a hub in EU enlargement in Eastern Europe. Big, small, and medium-sized businesses in Korea entered Hungary in the early 1990s since then, there has been a significant increase in Korean presence, of approximately 130 times. This study aimed to identify the key distribution issues that have emerged in relation to Eastern Europe. Research design, data, and methodology - This study indicates that 33 major Korean companies were located in Hungary, which serves as an out post to enter the European marketplace. However, Korea's exports to Hungary have declined (-32.0% in 2012) because of a loss of competitiveness against multinational corporations, due to factors such as the rise in current local distribution costs and wages. Hungary, on the other hand, through diversification and expansion of foreign trade with the non-EU markets, including Korea, is increasing its exports. Strategies of emerging countries are compared and reviewed in this study, by examining the vicissitudes of Hungary's distribution methods. Results - There are issues regarding Hungary's innovative ability. Hungary has a history of low wages and high skilled labor. However, the outflow of high-quality human resources for high-wages has become more extensive, and this underlines concerns that the CEE's trade hub is moving to neighboring countries. After the European financial crisis in 2010, the Hungarian economy is now developing, because of the IMF's measures, and it is being transformed into a trade surplus nation, while regaining distribution volumes rapidly. However, if there is continued lack of investment, the supply chain is weakened and exports decline amidst competition with TNCs or with China's distribution networks. Conclusions - It is necessary to create a new logistics approach for increasing trade between Korea and Hungary. First, Korean small and medium enterprises (SMEs) should build trust by working with advanced Hungarian talent, and they should expand into state-of-the-art fields instead of being confined to traditional sectors. Second, this study focuses on limiting and lowering their high expectations for success according to foreign direct investment (FDI) inflows and the role in the CEE distribution hub Korea should try to strengthen the distribution hub with its centralized population, using better, more highly educated human resources, thereby sustaining more innovative ability. Further, the positive effects of these measures are manifested in enhanced business on both sides of Hungary, namely, the EU and non-EU nations such as Turkey and emerging markets around Europe, and a better engagement in the core placement of culture and industry. For this, Korea can contribute to, and benefit from, a Hungarian logistics center, for adopting the high-tech cluster systems and commercializing distribution technology such as RFID·USN.

  • As we increase installing computers, traditional commerce by paper document is replaced by Electronic Commerce, paperless document commerce. Electronic Commerce proves to be an intermediary for increasing efficiency on work, which makes us use it more. This study aims to contribute to streamline local export by analyzing trade firms and manufacturers' using status of Electronic Commerce on work in Pusan. I sent questionnaires to 202 firms working on trade in Pusan to do survey. The sample of this study consists of 96 of them. I analyze using status of Electronic Commerce on work based on those data. The result shows that the more the firms install facility to be able for Electronic Commerce and the better they understand Electronic Commerce related laws, the more they select that on work. Generally The firms in Pusan rarely select Electronic Commerce on work and even acknowledges how much that is needed on work. Considering all of them, this study shows the method of streamlining local export by Electronic Commerce as follows; First, all kinds of Electronic Commerce such as trade related site in Internet should be systemized. Second, the laws on Electronic Commerce should be established in details. Third, workers on firms should be educated on Electronic Commerce. Forth, the firms should install the facility for Electronic Commerce, assist financially and make marketing strategy for selecting Electronic Commerce on each step in work. In conclusion, export in Pusan would be streamlined when the use of Electronic Commerce, effective intermediary, is motivated and we take that method to use on work properly.

  • 본 연구는 설문조사를 통해 수집된 대구 경북지역 기업 113개 업체를 대상으로 물류현황에 대해 업종별, 기업 규모별, 무역규모별, 화물 성격별 그리고 기업위치 지역별로 정성적 분석을 시도하였다. 특히, 이들 기업들의 3PL기업 이용에 영향을 미치는 기업특성 파악하기 위하여 수출입물동량, 취급 화물의 성격, 기업의 본사위치, 자사창고의 보유 여부를 예측변수로 사용하는 로짓 모형을 설정하였다. 102개의 유효데이터를 사용하여 모형을 추정한 결과, 수출입 물동량과 기업본사가 위치는 3PL기업의 이용에 10% 수준에서 통계적 유의성 가지고 있는 것으로 나타났다. 취급 화물이 부피화물인지의 여부, 자사창고보유 여부는 가정한 바와 같은 부호를 가짐에도 불구하고 통계적 유의성을 가지지 못하는 것으로 추정되었다. 이를 종합해 볼 때 본사가 대구 경북 이외의 지역에 위치하는 경우 3PL기업을 활용한 물류전략을 보다 많이 수행하는 것으로 해석 해 볼 수 있다. 나아가 수출입 물동량이 많을수록 통관, 검역 등 수출입 관련 전문물류업체인 3PL기업을 활용하여 물류 효율성 증대를 도모하고 있다고 할 수 있다.

  • 우리나라의 온라인 게임 산업의 급격한 성장은 새로운 규제의 문제를 발생시키게 되었는데, 가장 대표적인 것이 아이템 거래에 대한 규제 여부의 문제이다. 그런데 온라인 게임 아이템 거래 규제는 규제의 일환으로서 규제적 접근이 이루어질 필요성이 존재함에도 불구하고, 현재까지의 논리는 법 이론적 근거와 현실적 이유를 위주로 이루어지고 있으며, 규제 이론적인 접근은 이루어지지 못하고 있다는 한계점이 있다. 본 연구는 온라인 게임 아이템 거래 규제 논의에 대한 이러한 한계점을 보완하기 위하여, 독과점성, 외부성, 공공재성, 불확실성의 시장실패 여부 측면에서 아이템 거래 규제의 타당성 여부를 검토하였다. 분석결과 아이템거래는 시장의 독과점적 구조와 연관성이 없고 소비자 후생을 오히려 증가시키는 효과가 있다. 아이템은 완전한 경합성과 배제성을 지니고 있었으며, 게임산업 발전이라는 외부경제가 존재하였다. 아이템거래는 사이버범죄의 외부불경제와 연관이 있었으나, 이러한 부작용은 아이템거래 자체의 문제라기보다는 게임 회사가 아이템 거래를 적극적으로 금지하기 때문에 발생하는 문제였다. 따라서 시장실패의 틀에서 볼 때, 아이템 거래를 금지하지 않고 오히려 양성화하는 것이 현재의 부작용을 감소시킬 수 있는 정책적 방안이 될 수 있다.

  • 본 연구는 산업별 한국의 대 중국 직접투자가 대 중국 수출 및 수입에 미치는 산업내무역에 미치는 영향을 분석하여 시사점을 도출하고자 하는데 목적을 두고 있다. 이를 위해 산업을 표준국제무역분류(SITC)로 분류하였으며, 시계열회귀분석과 벡터오차수정모형(VECM)의 충격반응분석을 실시하여 대 중국 직접투자가 대 중국 수출 및 수입에 미치는 영향을 분석하였다. 본 연구의 결과를 요약하면 한국의 대 중국 직접투자는 대 중국 수출을 증가시키는 것으로 나타났으나 중국의 현지 국산부품조달의무(local content)비율 증가 등으로 대 중국 부품수출효과가 점진적으로 감소하는 것으로 나타났고, 대 중국 수입에 미치는 효과는 기타제조제품(가구, 가방, 의류, 신발등)에서 수입을 증가시키는 것으로 나타났다. 따라서 향후 대 중국 직접투자로 인한 한국의 무역수지 흑자폭은 점차 감소되어 질 전망이다. 한편 가공무역금지 등 중국의 현지투자환경 악화로 한국의 대중국 직접투자는 생산효율지향형 보다는 현지시장지향형의 특성이 강할 것이며 대 중국 직접투자의 비중도 장기적으로는 감소할 것이다.
