임수정,이준우 한국장애인고용공단 고용개발원 2011 장애와 고용 Vol.21 No.1

본 연구의 목적은 장애인근로자의 근로환경과 삶의 만족도의 인과관계를 설명하고 예 측할 수 있는 연구모형을 제시하여 요인들 간 직접ㆍ간접적 관계를 검증하는 데 있다. 이 를 위해 장애인고용패널 1차년도(2008년) 원자료를 사용하였으며, 임금근로자 1,211명을 대상으로 분석을 실시하였다. 본 연구에서 사용한 근로환경 요인은 직위, 고용형태, 채용 방법, 복리후생이며 직업유지기간, 임금 그리고 삶의 만족도와의 인과관계 검증을 위한 가 설을 설정하였다. 가설검증을 위해 SPSS 18.0과 AMOS 18.0을 사용하여 t-검정(t-test)과 일원변량분석(One-way ANOVA), 상관관계분석, 그리고 경로분석(Path Analysis)을 실 시하였다. 본 연구의 결과는 주요변인 간 차이검증에서 근로환경 요인 중 관리자급의 경우, 정규 직인 경우, 공개채용인 경우, 복리후생이 있는 경우에 직업유지기간, 임금, 삶의 만족도 평 균이 높게 나타났다. 또한 주요변인 간 인과관계 검증결과 관리자급이, 정규직인 경우에 직업유지 기간에 직접적인 영향을 미치고 있으며, 관리자급인 경우, 정규직인 경우, 공개 채용인 경우, 복리후생이 있는 경우 임금에 직접적인 영향을 미치는 것으로 나타났다. 또 한 복리후생이 있는 경우, 정규직인 경우, 그리고 임금이 높을수록 삶의 만족도에 직접적 인 영향력을 미치는 것으로 나타났으며, 임금이 근로환경요인과 삶의 만족도 사이에서 매 개효과를 내는 것으로 나타났다. 본 연구는 장애인근로자의 근로환경과 삶의 만족도 사이에 밀접한 인과관계가 성립되 고 있음을 밝힘으로써 직업정책의 관점이 개인적 관점에서 사회적 관점으로 변화되어야 할 필요성을 제기한다는 점에서 의의가 있다. The purpose of this study is to explain the causal relationship between the working environment of disabled workers and life satisfaction and verify the direct and indirect relationships between the factors through providing a research model. ‘Disabled Employment Panel’(2008) was used as a raw data and analysis was done with 1,211 employed workers as the subjects. Work environmental factors used in this study were job positions, types of employment, recruitment methods, welfare benefits and a hypothesis was set to verify the causal relationship between job maintenance period, wage and life satisfaction. To verify the hypothesis t-test (t-test), ANOVA (One-way ANOVA), correlation analysis and path analysis (Path Analysis) was carried out by using SPSS 18.0 and AMOS 18.0. The result of verifying the difference between main factors of this study showed that in the case of administrator level among work environment factors, as the work was a permanent position, an open recruitment, and had welfare benefits the average of job maintenance period, wage, and life satisfaction is higher. Moreover, the result of verifying the causal relationship between main factors of this study showed that as the administrator level is a permanent position it has a direct influence on job maintenance period and as the position is an administrator level, permanent, open recruited and have welfare benefits it has a direct influence on wage as well. Also, if you have welfare benefits in a permanent position with a high wage it has a direct influence on life satisfaction and found that wage has a mediating effect between work environment factor and life satisfaction. This study is meaningful because it raises the need for transformation of employment policy perspective from an individual one to a social one through identifying the close causal relationship between work environment and life satisfaction of disabled workers.

임수정,박희정,김현수,박세익,한상섭,김현준,이상현 한국산림과학회 2016 Forest Science And Technology Vol.12 No.4

The goal of the present study was to provide basic data for establishing climate change adaptation measures and to support appropriate forest management in Jeollabuk-do, Republic of Korea. An assessment of forest vulnerability to landslide caused by localized torrential rainfall was conducted for Jeollabuk-do, taking into consideration the local climate characteristics and the regional characteristics of the forest. CCGIS, a climate change adaptation software toolkit based on GIS, was used to carry out the vulnerability assessment of each city and county of Jeollabuk-do. To improve the assessment, locally specific variable weights were prepared, based on the results of a Delphi investigation targeting public forestry staff in Jeollabuk-do. The regionally specific weight was greatest for the variable of climate exposure, followed by sensitivity and adaptability. According to the vulnerability assessment over the course of time, in most of the forest the vulnerability rating decreased from 2000s to 2020s, and later it decreased once again in all urban areas. The vulnerability of forests was predicted to be greatest in the 2050s. Hence, if the local government sets up an adaptation policy using this research data that assessed the landslide vulnerability of forest in Jeollabuk-do, Korea taking account of the characteristics of the local area, we consider that an effective policy can be established and forest management can incorporate measures to adapt to climate change.

소셜미디어 분석을 활용한 재난안전산업 육성정책 수립방안

임수정,박덕근,Lim, Sujung,Park, Dugkeun 기술경영경제학회 2018 Journal of Technology Innovation Vol.26 No.1

다양하게 변화하는 재난양태와 기후변화로 인한 빈번한 재난발생뿐 아니라 생활수준 향상 등의 이유로 재난안전에 대한 국민적 관심이 증대되고 있다. 이와 연계하여 재난안전 산업에 대한 요구도 증가하고 있다. 그 동안 다양한 재난안전산업 육성 및 활성화 정책이 수립되었지만, 국가주도의 정책이 대부분이었고, 민간분야와 국민관심도가 반영된 정책은 부재한 상황이다. 따라서 본 연구에서는 국민관심도를 고려한 재난안전산업 육성방안 수립을 위하여 소셜미디어 분석을 활용하는 방안을 제안하고자 하였다. 재난안전분야의 국민관심도를 분석하기 위하여 최근 3년간의 소셜미디어를 대상으로 분석을 실시하였다. 분석 결과, 국민은 실제 발생했던 재난에 대한 내용, 즉각적으로 실생활에서 필요한 분야에 대해 관심도가 높은 것으로 나타났다. 또한 실제로 경주 지진발생 당시 재난 관련 소셜데이터가 급증하는 것으로 나타났고, 뉴스에서는 피해상황 등에 관한 내용이 많은 반면, 트위터와 블로그에서는 구호물품, 대피요령 등에 관한 내용이 주를 이루고 있는 것을 확인하였다. 본 연구의 결과로 국민적 관심도를 분석하기 위한 방법으로 소셜미디어 활용방안에 대한 가능성을 확인하였고, 재난안전산업의 민간분야 확산 차원에서 국민관심도를 반영한 재난안전산업 정책 수립방안을 제안한다. The general public's interest level towards safer life is increasing due to not only ever-changing faces of disasters and increased frequency of climate-change related disasters but also enhanced standard of living. Demand for disaster-safety industry is also increasing. Several policies for disaster-safety industry have been introduced. The policies, however, did not fully reflect the level of people's interest. This study is to investigate possible ways to reflect general public's interests towards disaster-safety industry using social media analysis, so that disaster-safety industry can be properly promoted. To examine the level of general public's interest, social media data during the last three years were compiled and analyzed. It was found that the interest level was highest towards, firstly, information on just-happened real disasters, secondly, necessary knowledge in real life which could be applied immediately if disasters strike. It was also confirmed that social media was useful in analyzing people's interest level quickly, because social data have been found to be sharply increased during the 2016 Gyeongju Earthquake in Korea. This study suggests applicable plans for disaster-related industry promotion based on social media data using general public's interest level.

Vitamin D in cancer: effects of pharmaceutical drugs on the vitamin D pharmacokinetics

임수정,김소희 한국약제학회 2014 Journal of Pharmaceutical Investigation Vol.44 No.5

Vitamin D is a fat-soluble vitamin and hasreported anti-cancer and anti-inflammatory properties aswell as bone homeostasis through the modulation of genetranscription and non-genomic signaling cascades. Thepurpose of this review is to summarize the availableresearch on pharmacokinetics of vitamin D analogues,especially 1a,25-dihydroxyvitamin D3 [1,25(OH)2D3, theactive form of vitamin D3] and the interactions betweenvitamin D and pharmaceutical drugs used in patients withcancer. Hypercalcemia was the most frequently reportedside effect that occurred in high doses of 1,25(OH)2D3. Thehalf-life of 25(OH)D3 and/or 1,25(OH)2D3 was found to beimpacted by cimetidine; rosuvastatin; prednisone andpossibly some chemotherapy drugs. No unusual adverseeffects in cancer patients were identified through thisreview beyond what is expected from high dose1,25(OH)2D3 supplementation such as the inconvenienceof high dose vitamin D. The supplementation with1,25(OH)2D3 during chemotherapy appears to have a lowrisk of interaction while sufficient evidence is still lacking. Further interactions with vitamin D3 and the developmentof new dosage forms for the therapy with high doses ofvitamin D3 need to be evaluated.

Tributyrin emulsion as a potent inhibitor of serum- or heregulinstimulated proliferation of colon cancer cells

임수정,Moon-Kyung Choi 한국약제학회 2012 Journal of Pharmaceutical Investigation Vol.42 No.2

Blockade of the heregulin-mediated growth signaling is important to prevent the proliferation of colon cancer. We previously reported that butyrate is a potent inhibitor of the heregulin-stimulated proliferation of colon cancer cells. While clinical use of butyrate is limited due to its very short plasma half-life, using tributyrin (TB) as a prodrug of butyrate may be an alternative solution. In the present study, we investigated a possibility to use TBincorporated emulsion as a potent inhibitor of colon cancer cell proliferation. When the growth of CaCo-2 and SNU-C4,two colon cancer cells, was stimulated by serum, TB emulsion exerted 2.8- and 5.7-fold higher inhibitory effect compared with free butyrate, based on the 50 % inhibitory concentration. When the growth of colon cancer cells was stimulated by heregulin, pretreatment with TB emulsion almost completely suppressed the heregulin-stimulated proliferation of cells at a concentration ineffective as butyrate. The more potent inhibition of heregulin-stimulated proliferation by TB emulsion was associated with more effective blockade of the activation of Akt and ERK1/2,which are important downstream molecules mediating hereuglin-stimulated proliferation of cancer cells. Taken together, TB emulsion is a potent agent that can inhibit the proliferation of colon cancer cells.

Intense Pulsed Light Sintered Core-Shell Nanoparticles for Organic Photovoltaic Devices

임수정,이지연,유재웅 한국고분자학회 2019 Macromolecular Research Vol.27 No.11

A fast and low-cost fabrication process using intense pulsed light sintering of metal nanoparticles was studied. Silver, copper, and four different copper-silver core-shell alloy nanoparticles were synthesized. The composition and resistivity of the sintered metal electrodes were studied. The resistivity of the silver electrode formed through nanoparticle sintering was comparable to that of a conventional solution-processed silver electrode. The performance of the device prepared using the copper nanoparticles only was low due to the oxidation of copper in the air. The current density-voltage (J-V) characteristics of the devices fabricated using the synthesized core-shell nanoparticles revealed that the alloy ratio up to approximately 2 did neither affect the performances nor the lifetime of the devices. As the content of copper increased, the device performance decreased due to the oxidation of copper. Usage of the sintered metal alloy electrodes resulted in the reduction of cost by 33% compared with the conventional silver electrode.

임수정,이민범,김세원,김장수,허수정,최승철,윤병성,김인종 한국토양비료학회 2016 한국토양비료학회지 Vol.49 No.4

The use of polyethylene film has a problem such as increasing rural environmental contamination, collection costs and farmers’ workload. The objective of this study was to evaluate bio-degradable films in terms of yield of maize and soil environment. Treatments were bio-degradable film A (BDF A), bio-degradable film B (BDF B), high density polyethylene (HDPE), and non-mulched (NM) soil. Daily mean values of soil temperature (10 cm depth) under BDF A, BDF B, and HDPE were higher than in NM soil by 2.2, 2.8, 3.1℃ respectively. In the mulching cultivation of maize, bio-degradable film began to degrade from 50~60days after the planting. The degradation was much progressed in the harvest time and almost decomposed in the following spring. The weight of ear of maize was not shown significantly by mulching treatments. There were little changes of soil chemical properties for the bio-degradable film mulching. After using bio-degradable films, the contents of biomass-C and dehydrogenase activity increased from 92 to 137~147 mg kg-1, and from 87 to 123~168 mg kg-1 respectively.
