Aimed at local restaurants, Gangwon-site visitor survey was adopted calling on the 462 valid samples. Using local restaurants via a synchronous market segmentation by customer type for the four clusters based on the multi-select attributes Multinomial Logit model was estimated. Gangwonmotivated type of local restaurants available for the analysis of factors affecting the results are as follows. First, Experience preferred groups (clusters 1) the purpose of use of the local restaurants, and select Properties from the area showed significant affect. Experience preferred groups (clusters 1) local restaurants for a meal using local foods and a lot of interest in quality and taste factors, while less concerned with convenience factor has been identified as a group. Second, the quality rave preferred groups (clusters 2) information learned by word of mouth housewives with their family and friends visited the local restaurants In addition, food quality and taste local factors and human services interest factors were identified by many groups. Third, the Internet and mass media as a source of information, promote a favorite groups (clusters 3) awareness of the physical environment and factors have been identified by many groups are interested in. Fourth, the preferred group of personalities (clusters 4) the income of the male guests, visiting relatives and the family physical environment and many groups are interested in is the convenience factor.

Purpose: The purpose of this study was to compare the bone regeneration effects of cortical, cancellous, and cortico-cancellous human bone substitutes on calvarial defects of rabbits. Methods: Four 8-mm diameter calvarial defects were created in each of nine New Zealand white rabbits. Freeze-dried cortical bone, freeze-dried cortico-cancellous bone, and demineralized bone matrix with freeze-dried cancellous bone were inserted into the defects, while the non-grafted defect was regarded as the control. After 4, 8, and 12 weeks of healing, the experimental animals were euthanized for specimen preparation. Micro-computed tomography (micro-CT) was performed to calculate the percent bone volume. After histological evaluation, histomorphometric analysis was performed to quantify new bone formation. Results: In micro-CT evaluation, freeze-dried cortico-cancellous human bone showed the highest percent bone volume value among the experimental groups at week 4. At week 8 and week 12, freeze-dried cortical human bone showed the highest percent bone volume value among the experimental groups. In histologic evaluation, at week 4, freeze-dried cortico-cancellous human bone showed more prominent osteoid tissue than any other group. New bone formation was increased in all of the experimental groups at week 8 and 12. Histomorphometric data showed that freeze-dried cortico-cancellous human bone showed a significantly higher new bone formation percentile value than any other experimental group at week 4. At week 8,freeze-dried cortical human bone showed the highest value, of which a significant difference existed between freeze-dried cortical human bone and demineralized bone matrix with freeze-dried cancellous human bone. At week 12, there were no significant differences among the experimental groups. Conclusions: Freeze-dried cortico-cancellous human bone showed swift new bone formation at the 4-week healing phase,whereas there was less difference in new bone formation among the experimental groups in the following healing phases.

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.
호텔 직원이 지각한 조직공정성이 열정 및 친사회적서비스행동에 미치는 영향
이덕원 한국호텔리조트학회 2020 호텔리조트연구 Vol.19 No.4
The purpose this study is to examine the effect of organizational justice on passion and pro-social service behavior. In order to verify the hypothesis, this study conducted a questionnaire survey on 230 hotel employees in 5 star, 10 hotels in Seoul. The results of the analysis are as follows. First, organizational justice has a positive(+) effect on harmonious passion. Second, harmonious passion has a positive(+) effect on prosocial service behavior in the role. Third, harmonious passion has a positive(+) effect on extra-role prosocial service behavior. It is suggested that the organizational members who are the internal customers of the hotel company have the influence of the passion on the value of the organizational justice and thus the organizational maintenance and human resources management of the hotel companies efficiently with the pro-social service behavior that can maximize their abilities.

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.
