홍정훈(Hong, Jung-Hun),박상연(Park, Sang-Yun) 한국경영교육학회 2020 경영교육연구 Vol.35 No.4
[연구목적] 본 연구의 목적은 컨설팅을 받은 수진기업(受診企業)들을 대상으로 컨설팅 참여도 요인이 컨설팅 재구매 의도에 미치는 영향을 실증분석하는 것이다. 또한 수진기업의 당해 컨설팅에 대한 이해도가 컨설팅 재구매 의도에 대해 조절효과를 가지는지에 대해 추가적으로 분석한다. [연구방법] 본 연구에서는 기존에 수행되었던 관련 국내외 연구들에 대한 검토 및 관련 실무 담당진과의 면담을 통해 6개의 연구가설을 도출하였다. 이에 대한 검증을 위해 국내 중소기업의 컨설팅 참여도 · 이해도 및 컨설팅 재구매 의도에 관한 자료를 수집하였고, 수집된 자료에 대해서는 신뢰성과 타당성을 검토하였다. 또한 구조방정식 모형 분석을 통해 연구가설을 검증하였다. [연구결과] 연구 결과 컨설팅 재구매를 높이기 위해서는 수진기업의 참여도 제고와 함께 컨설팅 이해도를 높이는 노력이 동시에 필요함을 실증적으로 검증하였다. [연구의 시사점] 본 연구에서는 기존의 연구들에서 상대적으로 간과되었던 컨설팅 수진기업의 컨설팅 참여도 · 이해도 요인이 컨설팅 수행 성과 및 매출 증대와 관련하여 중요한 결정요인임을 실증적으로 분석하였다. 본 연구의 결과는 향후 관련 분야의 후속연구에 이론적, 실무적 시사점을 제공할 것으로 기대된다. [Purpose] This study empirically assessed the extent to which consulting companies have increased their participation in consulting in some cases or situations, and how this affects consulting repurchases. In addition, we empirically assessed whether clients’ understanding of consulting affects the intention of consulting repurchase. [Methodology] For this purpose, we described prior literature review and we examined various researches to provide understanding of relationships with strategic account. Six hypotheses were drawn from the previous researches. To verify these hypotheses, data were collected through survey, and the data were tested by reliability, validity, correlation, structural equation modeling analysis. [Findings] As a result of the study, it is proven that both customer participation and consulting understanding need to be enhanced to increase consulting repurchase. [Implications] This study can see that it is important to conduct the consulting in order to participate in the role and process of the client’s personnel and to improve the understanding of consulting.

Purpose: Air pollution would increase the risk of acute myocardial infarction (AMI). The aim of this study is to determine whether a relationship exists between air pollution and the occurrence of AMI in Korea. Methods: From Korean AMI Registry, 4,168 Koreans admitted for AMI in four hospital in Daegu between January 2006 and October 2010 was included in this study. The dates for onset of cardiac symptoms were merged with atmospheric pollutants including atmospheric particulate matter with diameter of 10 micromeres or less (PM10), ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur dioxide (SO2). Poisson regression model was carried out. Results: There was asignificant negative relation between daily occurrence of AMI and the mean concentration of NO2. A 1/1,000 ppm decrease in mean concentration of NO2 was associated with a 2% increase of occurrence of AMI (β=-0.020, risk ratio=1.020, p<0.0001). This association was consistently observed regardless of gender (β=-0.0195, risk ratio=1.0196, p <0.0001 for males vs. β=-0.0211, risk ratio=1.0213, p<0.0001 for females) and age (β=-0.0210, risk ratio=1.0212, p<0.0001 for <65-years-old vs. β=-0.0192, risk ratio=1.0193, p<0.0001 for ≥65-years-old). There were significant positive relations between daily occurrence of AMI and the mean concentration of CO and SO2. A 1/10 ppm increase in mean concentration of CO (β=0.067, risk ratio=1.069, p<0.0001) and 1/1,000 ppm increase in SO2 (β=0.026, risk ratio=1.026, p=0.0078) were associated with 6.9% and 2.6% increase of occurrence of AMI, respectively. This association, particularly in CO, was stronger in females (β=0.0943, risk ratio=1.099, p<0.001 for females vs. β=0.0529, risk ratio=1.054, p=0.0003 for males) and in the young (β=0.0703, risk ratio=1.073, p<0.0001 for <65-years-old vs. β=0.0627, risk ratio=1.065, p=0.0001 for ≥65-years-old). There were no significant associations between concentrations of PM10 (β=-0.0002, risk ratio=1.0002, p=0.68) and O3 (β=-0.0032, risk ratio= 1.003, p=0.059) and occurrence of AMI. Conclusions: These finding suggests that air pollution have a modest influence on the occurrence of AMI in Korea.
Strength Properties of Recycled Aggregate Concrete Mixed with Polypropylene Fiber
Hong, Seong Uk,Lee, Yong Taeg,Kim, Seung Hun,Baek, Sang Ki,Cho, Young Sang Trans Tech Publications 2011 Applied mechanics and materials Vol.147 No.-
<P>This research is to verify and propose the practical use of recycled aggregate concrete which is one of the recycling methods of construction wastes. This is because domestic construction industries have been more sustainably developed, and renovation and redevelopment of buildings for increasing the quality of life have been actively performed because the necessity of efficient management of construction wastes has been increased. In addition, the possibility of increased quality focused on recycled aggregate concrete with mixed polypropylene fiber was proposed on this research through material experiments basedon compressive and split tension strength.</P>

Background and aim The rate of venous thromboembolism (VTE) has gradually increased within the Korean population. This third nationwide population-based epidemiologic study aims to evaluate the annual age- and sex- and sex-adjusted rates (ASR) of VTE and anticoagulation trend between 2014 and 2018. Methods Using the Korean Health Insurance Review and Assessment Service database, we retrospectively identified VTE patients between 2014 and 2018 by using both diagnostic and medication anticoagulant codes assigned within six months of the initial index event. Patterns of anticoagulants were classified as follows: DOAC-based regimen; UFH and/or LMWH regimen; warfarin-based regimen; and mixed anticoagulation regimen. Results We identified 95,205 individuals with VTE (54,085 female, 56.8%). The ASR for VTE per 100,000 person-years increased from 32.8 in 2014 to 53.7 cases in 2018 (relative risk of 1.63; 95% CI, 1.6 to 1.67; p-value < 0.0001) (Figure 1). The VTE incidence rates are 25 times higher in the 80 or older group than the 30s group. The VTE in females occurred 1.29 times more often than males. The proportion of DOAC-based prescription increased from 40.5% to 72.8%, whereas warfarin-based prescription from 27% to 5.6% in 2014 and 2018. Conclusion In Korea, ASRs of VTE continued to increase since 2014, but the rate of increase has slowed in 2018. The VTE incidence rate are higher in elderly group than the middle-aged group. The VTE in females occurred more often than males. Five years after DOACs were introduced in 2013, they account for 73% of all anticoagulants used to treat VTE.
