이이내,안경희,양미희,최인철,정현미,이원석,박주현,Lee, Leenae,Ahn, Kyunghee,Yang, Mihee,Choi, Incheol,Chung, Hyenmi,Lee, Wonseok,Park, Juhyun 한국물환경학회 2017 한국물환경학회지 Vol.33 No.4
The subject samples include 150 and 170 samples collected from intake holes in the former and latter half of 2015, respectively. They were analyzed with ICP-MS. The average concentration of detected barium was $10.54{\mu}g/L$ ($0.23{\sim}168.22{\mu}g/L$) and $8.21{\mu}g/L$ ($0{\sim}255.65{\mu}g/L$) for the former and latter halves of 2015, respectively. The concentration distribution was the highest for the precambrian era at $19.07{\mu}g/L$ and the lowest Cenozoic era at $4.92{\mu}g/L$. The average value for sedimentary, metamorphic, and igneous rocks was $7.84{\mu}g/L$, $20.84{\mu}g/L$, and $9.47{\mu}g/L$, respectively, which indicates that it was the highest for metamorphic rocks. The study also analyzed correlations between barium and other minerals and found that magnesium recorded 0.44 and 0.71 for the former and latter half of 2015, respectively. As for barium concentration according to depth, it was relatively low in shallow groundwater (under 200 m) with its average concentration at $14.33{\mu}g/L$ and $14.71{\mu}g/L$ for the former and latter half of 2015, respectively. It was $8.53{\mu}g/L$ and $4.04{\mu}g/L$ in deep groundwater (over 200 m) for the two periods, respectively, The risk assessment results show that its average risk was HQ 0.00139 and HQ 0.00163 for the former and latter half of 2015, respectively, being considerably lower than "1", which suggests that barium poses few possibilities of consumption risk.

국내 샘물에서 몰리브덴(Mo)의 수질 특성에 관한 연구
이이내,손보영,양미희,최인철,박상민,이원석,박주현 한국환경분석학회 2017 환경분석과 독성보건 Vol.20 No.4
This study examines the Molybdenum content in the water source at bottled water manufacturing facilities across the country and its geographical and geological distribution characteristics. This study also reviews the need for prior risk management in assessing the risk of Molybdenum. The subject samples include 147 and 152 samples collected from intake holes in 2015 and 2016, respectively. They were analyzed with ICP-MS. The average concentration of detected Molybdenum was 4.44 μg/L (0~31.68 μg/L) and 3.21 μg/L (0~29.76 μg/L) for the 2015 and 2016 samples, respectively. The detection rates were 98.3% and 98.7% for the two periods, respectively. The distribution in Molybdenum content was the highest during the Mesozoic era, at 5.78 μg/L, and the lowest during the Paleozoic era at, 0.96 μg/L. The average values of sedimentary, metamorphic, and igneous rocks were 6.22 μg/L, 2.09 μg/L, and 5.02 μg/L, respectively, which indicates that it was highest for sedimentary rocks. This study also analyzes correlations between Mo and other minerals and discovered that Na recorded 0.47, As 0.34, SO4 0.29, confirming the correlations between Mo and other minerals. Other elements including Ca, Mg, K, U, Sb, V, Cu, Ba, Fe etc., had little correlations with Mo. The risk assessment results show that the average risk was 0.021 HQ and 0.015 HQ for the 2015 and 2016 samples, respectively. These results are considerably lower than “1” and suggest that there are few possibilities of Mo consumption risk.

전시주최자의 형태에 따른 전시서비스품질이 참가업체 성과 만족에 미치는 영향
이이내,김봉석 한국무역전시학회 2019 무역전시연구 Vol.14 No.1
The purpose of this study is to investigate the effect of exhibit service quality according to organizer types on exhibitor’s satisfaction. The exhibition organizer is divided into two types as a private organizer and an association/organization organizer. Exhibition service quality consisted of five factors which are tangibles, reliability, empathy, assurance, and responsiveness. Participant performance was divided into two categories: sales activities and communication activities. The questionnaires were given to 165 people to the exhibition held in KINTEX. As a result of analyzing the effect of exhibition service quality factors on the performance of sales activities among the participant companies' performance, reliability, tangibility and empathy were found to be significant, and the influence on the communication activity performance was analyzed results showed that empathy was significant. Second, the empathy was found to be a factor in the quality of the exhibit service provided by the private organizer as a factor in the performance of the exhibitors' sales activities and communication activities. The results of this study were as follows: First, the exhibitors' service quality was significantly related to the performance of sales activities given by the association/organization organizer’s performance.In other words, empathy among the exhibit service quality factors provided by the exhibitors of the private and association/organization organizer has a common effect on the sales and communication activities among the exhibitors' performances. 본 연구는 전시주최자의 형태에 따른 전시서비스품질이 참가업체 성과만족에 어떠한 영향을 미치는지 알아보고자 하였다. 전시주최자 유형은 전시장을 소유하지 않은 민간 전시주최자와 협/단체 전시주최자, 총 2가지 형태로 나누었으며, 전시서비스품질 요인은 서비스품질 선행연구를 참고하여 유형성, 신뢰성, 공감성, 응답성, 확신성, 총 5가지 요인으로 구성하였다. 참가업체 성과만족도 역시 선행연구를 참고하여 판매 활동과 커뮤니케이션 활동, 총 2가지 항목으로 구성하였다. 연구검증은 SPSS를 활용하여 회귀분석을 활용하여 분석하였다. 분석결과 전시서비스품질요인이 참가업체 성과 중 판매 활동에 영향을 미치는 요인으로는 신뢰성, 유형성, 공감성이, 커뮤니케이션 활동에 영향을 미치는 요인으로는 공감성이 유의한 것으로 나타났다. 세부적으로는 민간 전시주최자가 제공하는 전시서비스품질 요인 중 참가업체 성과 중 판매 활동과 커뮤니케이션 활동에 영향을 미치는 요인은 공통적으로 공감성이 유의한 것으로 나타났다. 협/단체 전시주최자가 제공하는 전시서비스품질 요인 중 참가업체 성과 중 판매 활동에 영향을 미치는 요인은 공감성이 유의한 것으로 나타났고, 커뮤니케이션 활동에 영향을 미치는 요인은 유형성과 공감성이 유의한 것으로 나타났다. 즉, 민간과 협/단체 주최자 공통적으로 제공하는 전시서비스품질 요인 중 참가업체 성과 중 판매 활동과 커뮤니케이션 활동에 영향을 미치는 요인은 공감성으로 나타났다. 연구결과를 바탕으로, 전시주최자는 참가업체와 원활한 소통을 할 수 있어야 하며, 전시회에서의 성공을 이루기 위해 상호 간의 구체적인 비전을 나눌 수 있어야 한다. 또한 주최측은 참가업체의 이익추구(특히 판매 활동)를 위해 노력해야 하며, 그들이 필요로 하는 사항이 무엇인지를 파악하여 제공하도록 노력해야 한다는 결론이 나온다. 이 연구가 전시주최자와 참가업체 간의 성공적인 발전을 증진시킬 수 있는 계기가 되었으면 한다.

이내화,Lee, Nae-Hwa 벤처기업협회 2006 벤처다이제스트 Vol.95 No.-
행복한 인생은 하나의 과학이다. 행복이란 저절로 이루어지는 것이 아니라 '구체적인 계획'과 이에 따른 '지속적인 행동' 그리고 '성취'라는 연결고리를 통해서 나오는 결과물이기 때문이다. 지금부터 2006년 인생의 중간 점검에 들어가 보자. 이 작업은 당신의 희망찬 후반전을 구상하는 '2006년 하프타임 워크숍'이다.
