Every organization needs to maintain its long-term effectiveness through the positive perceptions, attitudes, and behaviors of its members. Customer orientation, job satisfaction, and organizational citizenship behavior (OCB) are the important functioning aspects for the long-term organizational effectiveness. The purpose of this study is to investigate the impact of service-worker's customer orientation on OCB within Korean bank and insurance sector by analyzing the relationship of constructs in the conceptual model. To achieve research objectives, survey method is employed. Findings of this research reveal that both need and enjoyment dimension of CO are very important in predicting OCB. We sent 220 questionnaires to service workers of the bank and insurance then received 200 valid responses. The research was conducted in bank and insurance agency in J city. The choice of these two types of organizations was dictated by the fact that they have large number of service worker with diverse background at multiple levels in these industries. Results also indicated that the moderating effect of pay satisfaction on the relationship between their OCB and CO had a weak effect.

Objectives: This study aimed to provide basic data on ways to facilitate effective communication between patients and dental hygienists, to improve the job satisfaction of dental hygienists, and to reduce the turnover rate among dental hygienists. Therefore, a comparative analysis of the perception of dental hygienists' emotional labor was conducted targeting patients and dental hygienists. Methods: Data were collected from August 1 to September 20, 2018, from 367 participants, including 216 dental hygienists and 151 patients residing in Gwangju, Jeonnam. Using the co-orientation model, their perception of dental hygienists' emotional labor was analyzed through the independent t-test and paired t-test. Results: With reference to objective consistency, patients showed a higher perception of dental hygienists' emotional labor than dental hygienists did, indicating that the former perceived the emotional labor more negatively. Regarding accuracy, there were significant differences in dental hygienists' response to six questions, while the same was observed for 11 questions for patients. Thus, the accuracy of dental hygienists was relatively higher than that of patients. Conclusions: To help dental hygienists perform dental health prevention activities more actively, consistently, and happily, and to establish commitment and professionalism in dental hygienists to enhance national dental health. Additionally, it would be necessary to sustain continuous research interest on measures for understanding the co-oriented relationship between patients and dental hygienists, and to solve the negative elements of dental hygienists' emotional labor.

Purpose - This study is to examine the effect of environmental orientation on innovation, environmental and market performance in Korean franchise firms' context. This study also investigates how environmental orientation, innovation and environmental performance play mediating roles between environmental orientation and market performance. For these purposes, the authors developed a structural model which consists of several constructs. In the model, environmental orientation was proposed to affect innovation and environmental performance, while innovation and environmental performance influence market performance. Specifically, innovation and environmental performance were proposed as core mediators between franchise firms' environmental orientation and market performance. Research design, data, and methodology - The data were collected from 155 franchise firms in Korea during January 2012. The results of factor analysis with reliability test with Cronbach's α warranted unidimensionality of the measures for each construct. In addition, nomological validity of the measures of each construct was warranted from the result of correlation analysis. The data were analyzed with reliability analysis, and structural equation modeling with SPSS Win/PC 18.0 and AMOS 18.0. Results - The results of the overall model analysis appeared as follow: χ²=52.388(df=21), p=.000. GFI=.932, AGFI=.854, NFI=.964, CFI=.978, RMSEA=.099, RMR=.059. Since the result of the overall model analysis demonstrated a good fit, we further analyzed our data. The findings can be summarized as follows: Firstly, the environmental orientation had a positive effect on innovation and environmental performance, but had not a direct effect on market performance. Secondly, innovation had a positive effect on environmental performance, but had not a direct effect on market performance. Thirdly, environmental performance had a positive effect on market performance. Conclusions - The results of this study show that, in order to achieve competitive advantages and environmental and market performance in turbulent market situation, franchise firms should emphasize internal and external environmental orientation, and put through improvements in perspective of technology, organization, and product. Consequently, this research suggests that environmental orientation is a motive for franchise companies' innovation, environmental performance, and market performance. It also suggests theoretical and managerial implications, limitations, and further research directions.

There have been a series of mixed reviews on the 'untact work' which was implemented for the safety of the organizational members from Covid-19. This study reports a follow-up study with a quantitative approach to issues identified by in-depth interviews with workers and managers who have experiences in work from home. To compare the views of workers and managers on untact work, 264 workers and 141 managers were surveyed. An analysis of agreement, congruency, and accuracy on the basis of the co-orientation model shows that workers are more positive about the untact work than managers and that managers are found to have a negative perception on untact work. This seems to be a burden on workers. More specifically, managers and workers show significant perception gaps on the issues of unfair evaluation and work-life balance. The results imply that organizations need to make efforts to minimize the perception gaps between workers and managers. This would bring about benefits from untact work.

We present a region-based approach for accurate pose estimation of small mechanical components. Our algorithm consists of two key phases: Multi-view object co-segmentation and pose estimation. In the first phase, we explain an automatic method to extract binary masks of a target object captured from multiple viewpoints. For initialization, we assume the target object is bounded by the convex volume of interest defined by a few user inputs. The co-segmented target object shares the same geometric representation in space, and has distinctive color models from those of the backgrounds. In the second phase, we retrieve a 3D model instance with correct upright orientation, and estimate a relative pose of the object observed from images. Our energy function, combining region and boundary terms for the proposed measures, maximizes the overlapping regions and boundaries between the multi-view co-segmentations and projected masks of the reference model. Based on high-quality co-segmentations consistent across all different viewpoints, our final results are accurate model indices and pose parameters of the extracted object. We demonstrate the effectiveness of the proposed method using various examples.

이 연구는 위험운전 행동에 대한 남녀운전자 상호간의 인식 차이를 다각적으로 비교, 분석하고, 인식 차이를 유발시키는 요인에 대한 파악을 목적으로 하였다. 위험운전 행동에 대한 상호인식 차이를 파악하기 위해 운전행동 분석도구인 DBQ(Driving Behavior Questionnaire)를 평가척도로 적용하였고, 그 결과를 상호지향성 모델(Co-orientation Model)에 적용시켜 남성운전자와 여성운전자의 상호 간 인식 차이를 비교, 분석하였다. 또한 요인분석을 통해 남녀 상호간 인식 차이를 발생시키는 요인을 도출하였다. 분석결과 객관적 일치도의 경우, 남녀 상호간 상대방의 운전행동이 더 위험하다는 인식차이를 확인하였고 주관적 일치도 또한 남성과 여성 모두 상대방이 자신의 실제 운전행동의 위험도보다 더 큰 위험도로 판단할 것으로 추측하여 차이가 나타났다. 정확도에서는 남성은 남성의 위험운전행동에 대해 본인의 추측보다 여성이 더 위험하게 인식하고 있는 것으로 나타나 판단이 어려우나, 여성운전행동에 대한 여성의 추측은 모든 요인에서 남성의 인식과 일치하여 남성을 정확하게 이해하고 있는 것으로 분석되었다. 또한 예측 모형의 결합을 통해 남성운전자의 관점과 여성운전자의 관점에서 비교분석하였으며, 그 결과 남녀 상호간에 상대방이 더 위험한 운전행동을 하는 인식을 갖고 있는 것으로 파악되었다.

최근 디지털 항공사진측량 분야에서 Direct Georeferencing 활용이 일반화되었으며, 이때 항공사진의 외부표정요소를 정확히 산출하기 위해 Boresight 검정이 필수적이다. 이 과정에서 높이에 대한 기준인 지오이드 모델을 사용하게 되는데, 지오이드 모델에 따라 Boresight 검정 결과가 다르게 나타날 수 있다. 본 연구에서는 Direct Georeferencing을 통한 외부표정요소 산출에 있어서 Boresight 검정시 지오이드 모델에 따라 그 값에 차이가 발생할 수 있음을 인지하고, 지오이드 모델이 Boresight 검정에 어떤 영향을 미치는지 세 가지 경우로 구분하여 실험하였다. 실험에 사용된 지오이드 모델은 EGM96, EGM08, KNGeoid14이며, 이에 따라 Boresight 검정을 통해 Datum Shift, Boresight Angle을 계산하였다. 또한 각각의 경우를 적용해 외부표정요소 산출 후 DPW(Digital Photogrammetry Worktation)를 이용해 지상기준점을 확인하였다. 본 연구를 통해 지오이드 모델에 따른 Boresight 검정 결과 Datum Shift에서 Z에서 차이가 있었으며, 외부표정요소에서 높이 Z와 회전량 Ω, Φ에서 차이를 보였다. 각각의 경우에서 수치도화기를 이용해 지상기준점과 비교한 결과 지오이드 모델에 따른 관측정확도의 차이는 3cm 내외로, 지오이드 모델이 Boresight 검정에 큰 영향을 미치지 않음을 알 수 있었다.

The conformational study on malonic acid, hydrogen malonate, malonate, malonyl methyl sulfide, and malonyl methyl sulfide anion, as the model compounds of malonyl-CoA, was carried out using the semiempirical MO methods (MNDO, AM1, and PM3) and hydration shell model. On the whole, the feasible conformations of malonic acid, hydrogen malonate, and malonate seem to be similar to each other. In malonic acid and malonate, two carboxyl groups are nearly perpendicular to the plane of the carbon skeleton, despite of different orientation of two carboxyl groups themselves. In particular, two carboxyl groups of hydrogen malonate are on the plane formed by carbon atoms with an intramolecular hydrogen bond. The calculated results on the geometry and conformation of three compounds are reasonably consistent with those of X-ray and spectroscopic experiments as well as the previous calculations. The orientation of two carbonyl groups of malonyl methyl sulfide is quite similar to that of malonic acid, but different from that of its anion. Especially, the computed probable conformations of the sulfide anion by the three methods are different from each other. The role of hydration seems not to be crucial in stabilizing the overall conformations of malonic acid, hydrogen malonate, malonate, and malonyl methyl sulfide. However, the probable conformations of the unhydrated sulfide anion obtained by the MNDO and AM1 methods become less stabilized by including hydration. The AM1 method seems to be appropriate for conformational study of malonyl-CoA and its model compounds because it does not result in the formation of too strong hydrogen bonds and significant change in conformational energy from one compound to another.

This study analyzes difference in consumers' and front-line workers' perceptions on 'consumer complaint behavior with hateful intentions' though the Co-orientation Model in three dimensions. In addition, we seek to contribute to reducing the conflict between consumers and front-line workers in the service contact point by finding factors that affect the difference in perception between two parties. This study findings and implications are as follows. First, Taking a look at the mutual orientation between consumers and front-line workers, mutual perceptions have been found to match in agreement but with a significant difference in perceived agreement (congruence), which indicates that the internal perceptions of both consumers and front-line workers do not match. The findings confirm that consumers and front-line workers have different perspectives on consumer complaint behavior with hateful intentions and therefore raise a need for efforts and institutional devices for improvement. Second, the study has found that consumers' economic responsibility as part of their social responsibilities and front-line workers' perceptions on consumers' civic responsibility affect the perception difference between these two groups and suggest a need for educating consumers about economic responsibility. Meanwhile, unlike consumers, front-line workers view consumers' complaint behavior with hateful intentions from an ethical point of view, raising a need for a transition of perspectives on complaint behavior with hateful intentions.
