변혁적 리더십과 조직시민행동의 관계에서 호텔직원의 감성지능 조절효과
이덕원,서광열 한국호텔관광학회 2011 호텔관광연구 Vol.13 No.2
The purpose of this study was to examine the moderating effects of Emotional Intelligence in the Relationship between transformational leadership and organizational citizenship behavior (OCB) of hotel employees. The model was tested using SPSS 12.0 based on a sample of 332 surveys. Factor analysis revealed a two-dimensional factor structure for transformational leadership, and four- dimension for emotional intelligence, and a three-dimensional factor structure for OCB. The result indicated that hotel employees who a high degree of transformational leadership show positive OCB. Also the result showed emotional intelligence of hotel employee had significantly positive effect on OCB. Also the result showed that emotional intelligence of hotel employees had significantly moderation effects of the relation between transformational leadership and OCB.

Accurate diagnosis of tumor and targeted drug delivery are prerequisites to effectively treat tumors withminimum side effects. In this study, beta-cyclodextrin (b-CD), polyethylene glycol (PEG), and folic acid(FA) were combined as aflatform (CDPF) to effectively transport adamantane (ADM) and near-infraredfluorophore (NIRF) conjugate (ADM-NIRF) to tumor target site. Using a tumor-bearing xenograft mousemodel, the supramolecular assembly exhibited excellent tumor targetability because the FA componentcould strongly bind to folate-receptors overexpressed in the membrane of MCF7 human breastadenocarcinoma cells compared to ADM-NIRF. These results indicate that CDPF-ADM-NIRF has potentialas a tumor diagnosis agent for clinical use.

Oral and maxillofacial surgery (OMFS) trauma cases are commonly treated under general anesthesia. The purpose of this case report is to introduce an alternative method of anesthesia in patients who refuse general anesthesia. A combination of dexmedetomidine and ketamine for sedation anesthesia in 3 frequent fracture types in the field of OMFS—Le Fort I fracture, mandibular fracture, and alveolar bone fracture—was used. Dexmedetomidine as the single agent has not shown stable success rates for invasive procedures. To overcome some of the pitfalls with dexmedetomidine, combination sedation using ketamine was performed. Visual analogue scale scores were recorded postoperatively. Dexmedetomidine combined with ketamine administration provided safe and effective sedation and anxiolysis for surgical reduction and internal fixation of OMFS fractures. It showed advantages of decreased admission time, reduced expenses, minimal pain, and reduced anesthetic burden for the patient thus ultimately increasing overall satisfaction.

고분해능 전자현미경법을 이용한 (Bi, La)<sub>4</sub>Ti<sub>3</sub>O<sub>12</sub> 박막의 결정학적 특성 평가
이덕원,양준모,박태수,김남경,염승진,박주철,이순영,박성욱,Lee, Doek-Won,Yang, Jun-Mo,Park, Tae-Su,Kim, Nam-Kyung,Yeom, Seung-Jin,Park, Ju-Chul,Lee, Soun-Young,Park, Sung-Wook 한국재료학회 2003 한국재료학회지 Vol.13 No.7
The crystallographic characteristics of the $(Bi, La)_4$$Ti_3$$O_{12}$ thin film, which is considered as an applicable dielectrics in the ferroelectric RAM device due to a low crystallization temperature and a good fatigue property, were investigated at the atomic scale by high resolution transmission electron microscopy and the high resolution Z-contrast technique. The analysis showed that a (00c) preferred orientation and a crystallization of the film were enhanced with the diffraction intensity increase of the (006) and (008) plane as the annealing temperature increased. It indicated a change of the atomic arrangement in the (00c) plane. Stacking faults on the (00c) plane were also observed. Through the comparison of the high-resolution Z-contrast image and the $Bi_4$$Ti_3$$O_{12}$ atomic model, it was evaluated that the intensity of the Bi atom was different according to the atomic plane, and it was attributed to a substitution of La atom for Bi at the specific atom position.
