Selective hydrodechlorination of chloroform to dichloromethane on Pt-Pd/KIT-6

이새롬,배종욱 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

Dichloromethane (CH₂CH₂), largely used in petrochemical industries as solvents and reactants, can be formed by selective hydrodechlorination of chloroform (CHCl₃) originated from hydrochlorination process as a main byproduct. To solve the environment problems, the utilization of chlorinated hydrocarbons through hydrodechlorination reaction has been largely investigated. In the present study, Pt-Pd bimetal catalysts showed a higher selectivity to dichloromethane by hydrodechlorination of chloroform without significant formation of methane at an optimal ratio of Pt/Pd on the KIT-6. To derive kinetic equations, catalytic reations at several different reaction conditions such as pressure, ratio of bimetals and space velocity and so on were carried out. The activity and selectivity were largely altered and proper kinetic parameters were derived based on the reaction mechanisms.

이새롬,김영삼 한국피부과학연구원 2018 아시안뷰티화장품학술지 Vol.16 No.3

목적: 본 연구는 천연성분 Ectoin의 피부 보습, 모공, 피부색, pH 등에 미치는 전반적인 효과를 규명하고자 하였다. 방법: Ectoin 분말 추출 시료는 클렌징폼, 토너, 크림, 로션으로 제조하여 실험군과 대조군에게 매일 아침, 저녁으로 2회씩 4주간 안면에 사용하 도록 하였다. 수집된 자료는 통계 프로그램 SPSS 24.0 for Windows를 이용하여 분석하였다. 결과: 유분의 경우, 대조군은 T존과 U 존 모두에서 유분 증가가 나타난 반면, 실험군은 T존에서는 유분이 감소하였고, U존에서는 유분이 증가하였다. 수분의 경우, 대조 군과 실험군 모두 수분이 증가했지만, 모든 항목에서 대조군보다 실험군의 수분 함유량 증가가 크게 나타났으며, 실험군은 턱을 제외한 모든 항목에서 수분이 유의하게 증가하였다. Transepidermal water loss (TEWL)의 경우, 대조군은 턱을 제외한 모든 항목에서 TEWL이 증가했고, 실험군은 모든 항목에서 TEWL의 감소를 나타냈다. 모공의 경우, 대조군에서는 모공의 증가와 감소가 교차 하는 경향을 나타냈지만, 실험군에서는 모든 항목에서 모공의 감소를 나타냈다. pH는 사전, 사후 모두 평균 4.5-6.5에 해당하는 피부의 정상 pH 범주를 보였으며, 유의한 변화는 나타나지 않았다. 피부색의 경우, 대조군의 멜라닌은 증가와 감소가 교차하는 반면, 실험군의 멜라닌은 좌우 모두에서 유의한 감소를 나타냈고, 홍반은 대조군과 실험군 모두 감소를 나타냈으나, 실험군의 홍반이 대조군에 비해 크게 감소하였다. 결론: 본 실험결과를 통해 천연성분인 Ectoin이 함유된 크림이 피부 보습 및 수분에 미치는 긍정적인 영향을 객관화, 수치화하였고, 이를 통해 화장품에 들어가는 천연 보습 원료로서의 가능성을 확인하였다. Purpose: The purpose of this study was to examine the overall effects of a natural ingredient Ectoin on moisture content, pore size, and tone of the skin. Methods: Ectoin was used for the production of a foam cleanser, toner, cream, and lotion. Experimental and control groups were provided with cosmetic samples with or without Ectoin, respectively, and instructed to apply them to their face twice a day in the morning and evening over a 4-week period. The data collected in this study were analyzed using the statistical software SPSS 24.0 for Windows. Results: Regarding oil contents, the control group showed increased oil contents at T- and U-zones, whereas the experimental group showed decreased oil contents at T-zones and increased oil contents at U-zones. Regarding moisture, although moisture contents increased in both the groups after the experiment, the experimental group exhibited a higher increase in moisture content than the control group across all facial areas. The experimental group showed statistically significant increase in moisture content on all facial areas excluding the chin. Regarding transepidermal water loss (TEWL), the control group exhibited increased TEWL values at all facial areas excluding the chin, whereas the experimental group showed decreased TEWL values at all facial areas. Regarding pore sizes, although the control group showed a pattern of alternate increase and decrease in pore sizes, the experimental group exhibited decrease in pore sizes at all facial areas. Regarding pH levels, both groups showed a normal pH range (4.5–6.5) before and after the experiment without any statistically significant changes. Regarding skin tone, the control group showed alternate increase and decrease in melanin, whereas the experimental group showed a statistically significant decrease in melanin on the left and right sides of the face. While both groups showed a reduction in red spots, the experimental group showed a greater extent of reduction in red spots than the control group. Conclusion: The above results indicate that the cream containing Ectoin as a natural ingredient has a positive effect on skin moisturizing and moisture, and it is confirmed to be a natural moisturizing raw material for cosmetics.

지식의 탐색(Exploration)과 활용(Exploitation)이 개방형협업의 성과에 미치는 영향: 오픈소스 소프트웨어 개발 프로젝트를 중심으로

이새롬,백현미,장정주 한국지식경영학회 2017 지식경영연구 Vol.18 No.2

With rapid development of information and communication technologies, open collaboration can be eased through the Internet. Open source software, as a representative area of open collaboration, is developed and adopted to various fields. In this research, based on organizational learning theory, we examine the impacts of exploration and exploitation on innovation performance in open source software development projects. We define knowledge exploration as a number of developers from outside organization and knowledge exploitation as the ratio of member of an organization who participated in an open source software project managed by the organization. For analysis, we collect data of 4794 projects from github which is a representative open source software development platform using Web crawler developed by Python. As a result, we find that excessive exploration has curvilinear (invers U-shape) relationship on project performance. On the other hand, exploitation with enough external developers will positively impact on project performance.

When in danger, who will help you? Two types of trust in technical coping on online platforms

이새롬 한국정보시스템학회 2023 情報시스템硏究 Vol.32 No.4

Purpose Social networking service (SNS) platforms employ distinct networking strategies to meet the varying needs of their users, resulting in divergent sets of technological functionalities offered by each platform. Consequently, unique features on various SNSs give rise to distinct social issues. Moreover, the available technical coping mechanisms for users vary significantly across platforms. Design/methodology/approach Therefore, this study analyzes the factors affecting technical coping intention based on technical functions of SNSs for users exposed to cybercrime, such as sexual harassment. We divide coping intention into active and passive coping intention. Furthermore, this research focuses on trust as an antecedent of coping intention and verifies how human and system-like trust affects two coping intentions in different directions. Findings Findings reveal that system-like trust significantly affects both active and passive coping intention as a belief in whether the technology will work properly. However, in the case of human-like trust, trust in the platform provider was found to negatively affect passive coping, which is considered unsocialized behavior on SNS platforms. Therefore, both human-like and system-like trust for the platform must be appropriately applied to cope with the problem while activating the platform.

18세기 耆老 모임 ‘驪江耆會’ 小考

이새롬 한국고전번역원 2023 民族文化 Vol.64 No.-

This study aims to examine the characteristics of the poems composed by the Yeogang Elderly Meeting and the works and consciousness of the literati in their age, whose works had not been introduced yet at that time. The Yeogang Elderly Meeting(驪江耆會) was a literary group organized in 1753 by Kim Jin-sang (1684~1755), Lee Gi-jin(1687~1755), Lee Gyu-jin(1688~1760), Min Wu-su(1696~ 1756) and others, who lived in the Yeoju area. The Yeogang Elderly Meeting, which was organized to celebrate Kim Jin- sang’s entering Giroso(a government office for the friendship and courtesy of high-ranking senior officials; 耆老所), was modeled in emulation of Nakyang Giyeonghoe(洛陽耆英會), where Wen Yanbo(文彦博) of the Song dynasty threw a feast at Fu Bi(富弼). However, the Yeogang Elderly Meeting took advantage of the topographical characteristics of Yeoju located along the Namhan River, and members traveled by boat when visiting each house, which is a differentiated feature. The works composed by the Yeogang Elderly Meeting, like those of a group utilizing the geographical features of the Yeo River(驪江), reveals the taste of those who enjoy boat cruises. In particular, the space where the meeting was held was emphasized, which is a feature distinct from other meetings for the elderly(耆老). This fact reveals that the four literati regarded the Yeogang Elderly Meeting as an aesthetic group(雅會), using it as a space(場) for sharing the excitement felt in traveling around Yeoju. Also, the four literati expressed their expectation that the Yeogang Elderly Meeting would be remembered even by the future generations as in the case of Nagyang Giyeonghoe. Such expectation is never found in the works composed by other senior groups in Yeoju. Through this, it can be seen that the Yeogang Elderly Meeting also motivated these four literati to continuously cultivate themselves so as to preserve their reputation and virtue(名德) even in their old age. The mood and poetry of the four literati demonstrate characteristics brought about by the consensus of those who face the experience of old age in Yeoju, a space of retreat, and it seems that their attitude as literati was manifested in their desire to lead a more leisurely and positive life in old age. ‘驪江耆會’는 1753년에 여주에 거주하였던 金鎭商(1684∼1755), 李箕鎭(1687∼1755), 李奎鎭(1688∼1760), 閔遇洙(1696∼1756) 등으로 구성된 모임이다. 본고는 ‘여강기회’에서 창작된 시의 특징을 고찰하여, 그동안 소개되지 않았던 문인들의 노년기 시와 의식을 살피고자 하였다. 여강기회는 김진상이 기로소에 들어간 것을 축하하기 위해 시작된 모임으로, 송대의 文彦博이 富弼의 집에서 술자리를 열었던 洛陽耆英會를 본받은 것이다. 다만 여강기회는 남한강을 끼고 있는 여주의 지형적 특징을 살려 각 집에 방문할 때, 배로 이동하였다는 차별화된 특징이 있다. 여강기회는 驪江의 지리적 특징을 활용한 모임답게 관련 작품에는 船遊를 즐기는 이들의 흥취가 드러난다. 특히 시에서 모임이 열리는 공간이 강조되었는데, 이는 다른 耆老 모임과 차별되는 특징이다. 이를 통해 네 문인들이 여강기회를 雅會로서 인식하였으며, 여주에서 느낀 흥취를 공유하는 場으로 활용하였음을 알 수 있다. 또한 네 문인은 낙양기영회처럼 여강기회도 후대에까지 기억될 것이라는 기대감을 시로 표출하였다. 이러한 기대감은 여주에서 다른 이들과 만났을 때 쓴 작품과는 차이를 보인다. 이를 통해 여강기회가 네 문인들에게 노년의 나이에도 끊임없이 名德을 가꾸도록 수양하는 기능도 하였음을 알 수 있다. 이와 같은 네 문인의 정취와 시상은 退老 공간인 여주에서 노년의 삶을 마주한 이들의 공감대에서 불러온 특징이자, 노년의 삶을 좀 더 여유롭고 긍정적으로 보내고자 한 문인으로서의 태도가 발현된 결과로 보인다.
