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.

<P>A feeding trial was carried out to determine the effects of chromium methionine (Cr-Met) chelate and forage level over two years, 1<SUP>st</SUP> fattening and 2<SUP>nd</SUP> fattening period on growth parameters, carcass characteristics and blood metabolites of 46 Korean native (Hanwoo, Bos Taurus, BW = 183 ± 44 kg) steers. Treatments were: 1) Steers in the low forage (LF) group were fed diets that consisted of 60% concentrate and 40% forage; 2) Steers in the high forage (HF) group were fed diets that consisted of 40% concentrate and 60% forage. Following the 1<SUP>st</SUP> fattening period, steers (BW = 480 ± 37.6 kg) were randomly assigned to four treatment groups: LF (40 F plus no Cr-Met supplementation in the 2<SUP>nd</SUP> fattening period), LFCM (40LF plus added 400 ppb of Cr-Met during the 2<SUP>nd</SUP> fattening period), HF (60 F plus no added Cr-Met during the 2<SUP>nd</SUP> fattening period) and HFCM (60 F plus added 400 ppb of Cr-Met in the 2<SUP>nd</SUP> fattening period). Dry matter intake of the treatment diets did not differ during the raising and 1<SUP>th</SUP> fattening period (P > 0.05). The ADG in the raising period showed no difference between the 40 F and 60 F groups (P > 0.05). Carcass characteristics including rib-eye area and meat yield index were higher in HF than the other treatment groups (P < 0.05). The HF group tended to show a higher (P = 0.08) marbling score than the LF group whereas the HFCM group showed a higher marbling score than the LFCM group (P < 0.05). HDL was higher and LDL lower in groups fed with Cr-Met than in other groups whereas glucose showed the lowest value in HF group (P < 0.05). Triglyceride (TG), Cholesterol, PUN and total protein (TP) were the same among all treatment groups (P > 0.05). The Insulin concentration in the blood was significantly higher for the HFCM group than for the LF, LFCM and HF groups (P < 0.05). It is concluded that supplementation of chromium-methionine chelate could improve meat quality in beef steers.</P>

<P>We developed a fiber-optic beta/gamma imaging detector that can obtain the scintillating images for beta-or gamma-ray emitted from the radioisotope. To evaluate spatial resolution of proposed imaging detector, we obtained the optical images using USAF 1951 resolution target. And then, a modulation transfer function curve of the optical image was calculated. Also, we measured the scintillating images of Tl-204 and Cs-137 with information respecting the beta-and gamma-rays distribution. Finally, the intensities of scintillating light as a function of radioactivity were analyzed from the region of interest in the scintillating image.</P>

Background and Objectives: The aim of this study was to demonstrate the efficacy and safety of treatment with drug-coated balloon (DCB) in a large real-world population. Methods: Patients treated with DCBs were included in a multicenter observational registry that enrolled patients from 18 hospitals in Korea between January 2009 and December 2017. The primary outcome was target lesion failure (TLF) defined as a composite of cardiovascular death, target vessel myocardial infarction, and clinically indicated target lesion revascularization at 12 months. Results: The study included 2,509 patients with 2,666 DCB-treated coronary artery lesions (1,688 [63.3%] with in-stent restenosis [ISR] lesions vs. 978 [36.7%] with de novo lesions). The mean age with standard deviation was 65.7±11.3 years; 65.7% of the patients were men. At 12 months, the primary outcome, TLF, occurred in 179 (6.7%), 151 (8.9%), 28 (2.9%) patients among the total, ISR, and de novo lesion populations, respectively. A history of hypertension, diabetes, acute coronary syndrome, previous coronary artery bypass graft, reduced left ventricular ejection fraction, B2C lesion and ISR lesion were independent predictors of 12 months TLF in the overall study population. Conclusions: This large multicenter DCB registry study revealed the favorable clinical outcome of DCB treatment in real-world practice in patient with ISR lesion as well as small de novo coronary lesion.
Effect of LiBiO2 on low-temperature sintering of PZT-PZNN ceramics
Hong Sung Cheul,Kim Shi Yeon,Yeo Dong-Hun,Shin Hyo-Soon,Park Zee Hoon,남산 한국세라믹학회 2022 한국세라믹학회지 Vol.59 No.5
In this study, the sintering characteristics of 0.69Pb(Zr 0.47 Ti 0.53 )O 3 -0.31Pb[(Zn 0.4 Ni 0.6 ) 1/3 Nb 2/3 ] (PZT-PZNN) ceramics after the addition of LiBiO 2 were studied. This addition lowered the sintering temperature from 1150 to 900 °C. The crystal structure changed from tetragonal to rhombohedral as the additive content increased by 0.7%. The polarization of the sintered specimen was conducted at an electric fi eld of 3 kV/mm. When 0.7 wt% of LiBiO 2 was added and sintered at 900 °C, the piezoelectric constant ( d 33 ) was 602 pC/N; moreover, the electromechanical coupling coefficient ( k P ), sintered density, and Curie temperature ( T c ) at 1 kHz were 66.3%, 7.99 g/cm 3 , and 252.8 °C, respectively. When 0.7 wt% of LiBiO 2 was added, the PZT-PZNN ceramic showed an increased strain curve of 0.118% at 2 kV/mm. The interdiffusion between the copper (Cu) electrode and ceramic material was not observed in the scanning electron microscopy (SEM) results; thus, the possibility of manufacturing an actuator using a Cu electrode using a novel composition was confirmed. The actuator displacement with the voltage 400 V was 1.2 μm. The thickness of the multi-layered actuator was 1 mm. Through this, the possibility of manufacturing a multi-layered actuator with a Cu electrode was confirmed through the composition of 0.69PZT-0.31PZNN (LiBiO 2 0.7 wt%).
