  • Purpose - Previous studies related to emotional labor of salespeople have mainly focused on identifying the antecedents of emotional exhaustion and turnover intention and exploring the mitigating effects salespeople's motivation on emotional exhaustion and turnover intention. They also demonstrates that there are different roles for moderating in social support, which means mental/physical support related to the job in supervisors, colleagues and organizations. The purpose of this paper is to investigate how service employees' surface acting affect turnover intention through emotional exhaustion. Another important objective of this paper is to investigate whether perceived social support moderates 1) the relationship between surface acting and emotional exhaustion 2) the relationship between emotional exhaustion and turnover intention. Research design, data, and methodology - To test the hypotheses, we collected the data from Korean insurance company sales employees. A total of 235 responses were received, from which 220 usable responses were obtained after list-wise deletion. Working with a sample of 220 responses, structural equation modeling was employed to empirically test research hypotheses(

    The relationship between surface acting and emotion exhaustion,

    The relationship between emotion exhaustion and turnover intention,

    The moderating effect of perceived social support(PSS) on the relationship between surface acting and emotion exhaustion, and

    The moderating effect of perceived social support(PSS) on the relationship between emotion exhaustion and turnover intention. SPSS 22.0 and AMOS software were used in these data analysis. Results - The service employees' surface acting was positively related to the emotional exhaustion; in turn, the service employees' feelings on emotional exhaustion are positively related to turnover intention. In addition, Perceived Social Support significantly moderated the relationship between surface acting and emotional exhaustion. However, perceived social support has a non-significant moderating effect on the path from emotional exhaustion to turnover intention. On the basis of these results, the following conclusion can be drawn. First, distribution service companies will be needed the administrative efforts to offer counseling programs and space to provide their members with enough rest in experiencing psychological pain due to the salespeople's surface acting. Also, it is necessary for distribution service companies to identify and share the examples of successfully solving emotional exhaustion caused by salespeople's surface acting.

  • 최근 정보기술의 발달과 대중화로 인해, 일반인들에게 지리정보의 보급이 확대되었고, 길찾기를 위한 인터넷 지도서비스나 혹은 차량항법장치 등은 공간의사결정에 지리정보시스템을 활용하는 좋은 사례라고 할 수 있다. 기존의 시스템이 제공하는 서비스에서 발견할 수 있는 문제점 중 하나는, 사용자가 그 지역에 처음 방문한 여행자이든 혹은 사용자가 그 지역에 지리를 어느 정도 알고 있는 거주자이든, 동일한 방식의 길찾기 방식이 적용된다는 점이다. 주어진 도시지역에 대한 공간지식은 거주기간에 따라 발달하게 되고, 도시이동은 공간에 대한 경험 속에서 발달된 인지지도에 많은 영향을 받게 되며, 이들의 공간적 지식의 발달은 그들이 속한 사회적 관계에 밀접한 영향을 받게 된다. 따라서 보다 인지적인 길찾기를 위한 서비스를 위해서는, 주어진 지역 내에서 사람들에게 잘 알려진 장소들, 다시 말해, 랜드마크를 통한 위치 인식이 중요한 역할을 하게 된다. 본 연구는 사회적 관계를 공유하는 한 지역 내 커뮤니티의 지역이동에 있어서 발달하는 인지지도를 하나의 공유된 지식으로 보고 이를 활용하는 도시공간이동에 대한 개념적 모델을 제시하였다. 이와 함께, 개념적 모델에 지식공학의 접근방식 중 하나인 온톨로지 방법론의 응용가능성을 살펴보았다. 지역 내 잘 알려진 공유된 랜드마크 지식을 지식모델링 기법의 하나인 온톨로지 방법으로 모델링하여 재사용가능한 지역지식으로 구조화하여 이를 공유 온톨로지라 정의하였다. 사례연구에서는 설문조사와 웹 내용분석의 방식을 통해 랜드마크의 추출하고, 온톨로지 방법론을 통해 사례지역 내 랜드마크 정보를 데이터베이스로 구성하여 활용하는 방안에 대하여 고찰하였다. 본 연구는 기계적 알고리듬으로만 제한된 현재의 GIS 기능을 인지적 모델과 접목을 도모하는데 큰 의미를 갖는다.

  • 본 연구의 목적은 창업가 웰빙의 중요성을 재조명하고, 이를 증진시킬 수 있는 방안을 모색하여 검증하고 제시하는데 있다. 먼저, 문헌연구를 통해 창업가 웰빙에 영향을 미치는 요인을 탐색하여, 긍정심리학의 배경에서 탄생한 긍정심리자본을 주요인으로 선정하였다. 그리고, 긍정심리자본과의 연관성이 예측되는 선행요인으로 진성리더십, 숙달목표지향성, 사회적지지를 선정하여 가설과 연구모형을 수립하였다. 수립된 모형의 실증적 분석을 위해, 청년창업사관학교 출신의 창업가들을 대상으로 설문조사를 실시하였다. 회수된 133부의 응답자료를 바탕으로 PLS구조방정식 분석과 다집단분석(PLS-MGA), 중요도-수행도 분석(IPMA)을 시행하였다. 실증분석결과, 긍정심리자본은 창업가의 웰빙과 매우 큰 인과관계가 있는 것으로 나타났고, 진성리더십과 숙달목표지향성은 긍정심리자본에 긍정적인 영향을 미치는 것으로 밝혀졌다. 하지만, 사회적지지의 영향에 대한 통계적 유의성은 검증되지 못했다. 창업초기와 성장기의 창업단계별 인과관계 차이는, 긍정심리자본의 하위요인에 대해서만 나타났는데, 세가지 선행요인들은 희망과 낙관주의에 대해서 각각의 유의한 차이를 나타냈다. 본 연구는 창업기업의 성과요인 규명 등에 편중되었던 국내 창업가정신 연구주제를 확장하였다. 창업기업의 핵심 주체인 '창업가'의 정신적 웰빙과 관련된 요인을 탐색하여 수립한 인과관계 모형을 실증적으로 검증했고, 이를 통해 창업가 및 연구자, 교육자에게 실무적 통찰력의 단서를 제시했다는 점에서 본 연구의 의의를 찾을 수 있을 것이다.

  • 우리나라 청소년들은 하루 중 대부분 시간을 학교에서 입시 위주의 교육으로 지낸다. 많은 시간을 학교에서 보내기 때문에 학교생활의 적응 여부는 청소년의 학업성취도 및 생활만족도와 관계가 있고 길게는 사회생활에까지 영향을 미치므로 그 중요성이 크다고 할 수 있다. 학교적응에 많은 영향을 미치는 요인 중의 하나로 청소년기의 심리적 불안을 고려해 볼 수 있다. 청소년의 가정환경은 불안에 영향을 미치는 주요 요인으로 알려졌으며, 그중 부부갈등이 가정환경에 미치는 영향력은 아주 크다고 할 수 있다. 가정에서 부부가 심하게 싸울수록 자녀는 분노, 슬픔, 걱정 등 부정적인 감정을 더 많이 느꼈으며, 부부갈등의 문제가 자녀 자신에 관한 내용일수록 그 정도는 더욱 심하게 나타났다. 본 연구는 이러한 이론적 배경을 근거로 부부갈등이 청소년의 불안과 학교적응에 어떻게 영향을 미치는가를 구조방정식 모형을 통하여 분석하였다. 분석결과 부부갈등 강도와 부부갈등 내용은 청소년의 불안감에 영향을 주었으며, 불안감은 학교 교우들과의 적응에 부정적인 영향을 미쳤다. 그러나 부부갈등 해결은 불안감에 영향을 미치진 않았지만, 학교 교우적응과 수업적응에 직접적으로 부정적인 영향을 미쳤다.

  • Objectives: It is well-known that post-traumatic stress disorder (PTSD) among firefighters contributes to their job-related stress. However, the relationship between burnout and PTSD in firefighters has rarely been studied. This study therefore explored the association between burnout and its related factors, such as trauma and violence, and PTSD symptoms among firefighters in Korea. Methods: A total of 535 firefighters participated in the Firefighter Research on Enhancement of Safety & Health study at 3 university hospitals from 2016 to 2017. The 535 participants received a baseline health examination, including questionnaires assessing their mental health. A Web-based survey was also conducted to collect data on job-related stress, history of exposure to violence, burnout, and trauma experience. The associations among burnout, its related factors, and PTSD symptoms were investigated using structural equation modeling. Results: Job demands (${\beta}=0.411$, p<0.001) and effort-reward balance (${\beta}=-0.290$, p<0.001) were significantly related to burnout. Burnout (${\beta}=0.237$, p<0.001) and violence (${\beta}=0.123$, p=0.014) were significantly related to PTSD risk. Trauma (${\beta}=0.131$, p=0.001) was significantly related to burnout; however, trauma was not directly associated with PTSD scores (${\beta}=0.085$, p=0.081). Conclusions: Our results show that burnout and psychological, sexual, and physical violence at the hands of clients directly affected participants' PTSD symptoms. Burnout mediated the relationship between trauma experience and PTSD.

  • Background: Due to the emergence of new diseases such as COVID-19, an increasing number of people are struggling with stress and depression. Interest is growing in forest-based recreation for physical and mental relief. Objectives: A prediction model equation using meteorological factors and data was developed to predict the quantities of medicinal substances generated in forests (monoterpenes) in real-time. Methods: The concentration of phytoncide and meteorological factors in the forests near Chuncheon in South Korea were measured for nearly two years. Meteorological factors affecting the observation data were acquired through a multiple regression analysis. A model equation was developed by applying a linear regression equation with the main factors. Results: The linear regression analysis revealed a high explanatory power for the coefficients of determination of temperature and humidity in the coniferous forest (R2=0.7028 and R2=0.5859). With a temperature increase of 1℃, the phytoncide concentration increased by 31.7 ng/Sm3. A humidity increase of 1% led to an increase in the coniferous forest by 21.9 ng/Sm3. In the deciduous forest, the coefficients of determination of temperature and humidity had approximately 60% explanatory power (R2=0.6611 and R2=0.5893). A temperature increase of 1℃ led to an increase of approximately 9.6 ng/Sm3, and 1% humidity resulted in a change of approximately 6.9 ng/Sm3. A prediction model equation was suggested based on such meteorological factors and related equations that showed a 30% error with statistical verification. Conclusions: Follow-up research is required to reduce the prediction error. In addition, phytoncide data for each region can be acquired by applying actual regional phytoncide data and the prediction technique proposed in this study.

  • In this work a multi-fidelity non-intrusive polynomial chaos (MF-NIPC) has been applied to a structural wind engineering problem in architectural design for the first time. In architectural design it is important to design structures that are safe in a range of wind directions and speeds. For this reason, the computational models used to design buildings and bridges must account for the uncertainties associated with the interaction between the structure and wind. In order to use the numerical simulations for the design, the numerical models must be validated by experi-mental data, and uncertainties contained in the experiments should also be taken into account. Uncertainty Quantifi-cation has been increasingly used for CFD simulations to consider such uncertainties. Typically, CFD simulations are computationally expensive, motivating the increased interest in multi-fidelity methods due to their ability to lev-erage limited data sets of high-fidelity data with evaluations of more computationally inexpensive models. Previous-ly, the multi-fidelity framework has been applied to CFD simulations for the purposes of optimization, rather than for the statistical assessment of candidate design. In this paper MF-NIPC method is applied to flow around a rectan-gular 5:1 cylinder, which has been thoroughly investigated for architectural design. The purpose of UQ is validation of numerical simulation results with experimental data, therefore the radius of curvature of the rectangular cylinder corners and the angle of attack are considered to be random variables, which are known to contain uncertainties when wind tunnel tests are carried out. Computational Fluid Dynamics (CFD) simulations are solved by a solver that employs the Finite Element Method (FEM) for two turbulence modeling approaches of the incompressible Navier-Stokes equations: Unsteady Reynolds Averaged Navier Stokes (URANS) and the Large Eddy simulation (LES). The results of the uncertainty analysis with CFD are compared to experimental data in terms of time-averaged pressure coefficients and bulk parameters. In addition, the accuracy and efficiency of the multi-fidelity framework is demonstrated through a comparison with the results of the high-fidelity model.

  • In the present age dominate by both cer-taingty of 1% and uncertainty of 99% 'Fuzzy thinking' of Bart Kosko that is the way to solve the problems by the scientific way through a worldview of Buddhism or Taoism greatly prevails around the world over 'Lateral greatly prevails around the world over 'Lateral thinking' and the authenticity or the right and-wrong of the uncertainty which is the thinking way to find the answer of the problems of illogical way of Edward de Beno against the western vertical thinking were Concurrently fashion designers over the world also adopt the oriental elements. But there exist differences of thoughts between the orient and the occident. And they have dif-ferent thinking way of aestheticism and references of the value on the beauty. Not only beauty but the view through the mind as intuitional thought in which not only the rec-ognition of sense but also the rationalism and the naturalness play key role. The aesthetic sense in the orient contains both the truth and virtue. 2) The beauty of the mean It's from the thought of neutralization of Confucius. The mean or moderation state which in harmony with ethical virtue and aes-thetic beauty is the ideal and is the ultimate. Therefore the thought of Confucian is the creativity in which the balance and the har-mony is most important. Fashion design is also one of the representation of the mean because the spirit of the designer is harmonized for-mlessly with the object of the model of the fashion design. 2) The beauty of skillfulness It indicates the Taoism of Lao-tzu and Chuangtzu. It takes a super-artistic declar-ation that human can feel and recognize the color of colorlessness the sound of sound-lessness and the taste of tastelessness. The thought of arts affected by Taoism is 'ad-vanced age' called the beauty of skillfulness. The view of arts of lao-tzu takes the beauty of cosmos and the nature as a standard. Es-pecially the beauty of inactivity is recognized by the linkage between the beauty and the ugliness. And these things appear in fashion design as a design element such as humor or exaggeration. 3) The beauty of non-dualism It is thought of Buddhism that all evil passions of worry occur form the opposition in dualism. Finally this thought leads to that everything is consistent and truth is only one from the point of view that virtue and vice has on linkage that is 'no virtues no vices' and 'one with two, two, with one, one is not two' A big tendency like this became the root forma-tion of the thought of the oriental arts. 3. Characteristics of the oriental aesthetic sense on the present fashion design 1) The formation of the fashion design on the oriental elements In the picture-incantation which was a representation of an era when the thought of 'cosmic dual forces' dominated the basic polygons of 'a circle square triangle' means both 'one two three' and 'the negative positive mean' of cosmic elements. From this point of view the was of planner cutting in the Orient is dif-ferent from that of the Occidental which is in three-dimensional. The planner polygon type of the cut-pieces comes to have the meaning of the three-dimension when they consist of a suit that has the combination of each cut-piece. This shows the consistency with the principle of cosmos creation of Taoism that one is two two is three and three is every-thing. 2) The coloring and the symbolic represen-tation of the fashion design on the orien-tal elements The sense on the colors in the Orient from the thought of 'the cosmic dual forces and the five elements' is not the experi-enced from the knowledge but contains the consideration of philosophy Five-primary-color representing compass directions Blue(East) Red(South) Yellow(Center) White (West) and Black (North) is called ' the posi-tive' for this five-primary-color secondary-color which comes from the compound of the primary colors is called 'the negative' The thought of 'the cosmic dual forces and the five elements' is also an theory containing the natural order of the cos-mos and this shows the perceptional differ-ence that they are not conceptual but to be recognized and fell directly. A thought of Buddhism which is 'Colors are colorlessness and Clolorlessness are color's proves that. 3) The pattern and symbolic representation of the fashion design on the oriental elements The pattern as a visual style is a figure of symbolic representation which adopt the mental and physical world of human and are the compo-sition of artistic revelation of the human nature and the religous thought of incantation. Es-pecially the symbolic representation of the oriental thought of Confusion. Buddhism and Taoism There are patterns such as plants aminals the oriental four gods and geometry. From the above it's the time toward the 21'th century when the world is constructing one global area and one historical zone. And the exotic mood of the Orient represented in the fashion which doesn't make the common feeling in general does not cease to develop only to express the visual modeling but also adopts the thought religion and the art which are the root of the Orientail and contains inherent willing of modeling.
