Statement of problem : A scientific examination and understanding of overall aspects of the natural dentition is the first step involved in making a satisfactory selection in the shade of an aesthetic prosthesis. Proper natural shade selection of the prosthetic restoration that is in harmony with the remaining dentition is as important aesthetically, as harmony of form and function in the anterior dentition. Clinically, the most commonly applied method of shade selection has been visual, but because of the subjective nature inherent to this method, shade selection results are variable and can be influenced by such factors as the technician, the type of shade guide used, and the type and intensity of the lighting. Purpose : The purpose of this study was to develop a more objective and scientific approach to examining and understanding the shade of teeth, which has in turn lead to the development of a number of shade analysis devices that present a more objective method of shade analysis. Material and Method : In this study, the shades of healthy anterior teeth were examined and analyzed using the recently developed digital shade analysis of the $ShadeScan^{TM}$ System. The study examined 80 individuals in their twenties, 40 males and 40 females, presenting 6 healthy, unrestored maxillary anterior teeth. Tooth brushing and oral prophylaxis were performed prior to evaluation. The ShadeScan handpiece was used to acquire images of the 6 maxillary anterior teeth. These images were analyzed using the Vita/Classical mode of the $ShadeScan^{TM}$ Software, and shade maps of each tooth were acquired and divided into cervical, middle, and incisal thirds. The shade distribution of each third, left and right symmetry, and gender differences were investigated and analyzed. Results : The results of the study are as follows : 1. An overwhelming majority of the examined teeth were found to possess shades belong to Group A, with the greatest variations occurring at the middle and cervical thirds of the maxillary central and lateral incisors, in both male and female subjects. 2. Canines of both male and female subjects showed left and right symmetry with uniform shade distribution of A4 and C4, while the lateral and central incisors showed left-right symmetry of the incisal 1/3 with a uniform shade distribution of A2 and A3 shades 3. No significant differences in shade distribution were seen between genders in maxillary canines, whereas maxillary central and lateral incisors showed differences at the middle and cervical thirds between male and female subjects The results of this study show that with the exception of maxillary canines, maxillary anterior teeth display a diverse shade distribution as well as gender differences. Conclusion : Clinically, when making a shade selection using the existing shade guide, one must consider the fact that even a single tooth consists of a variety of shades. The results of this study show that when selecting a shade from a number of groups is difficult, shades from A group are the most consistent with the natural shade or maxillary anterior teeth.

Purpose: The purpose of this study was to investigate actor and partner effects of sexual attitude and marital intimacy on sexual satisfaction in pregnant couples. Methods: Data were collected from 176 pairs of the pregnant couples visiting for prenatal care at hospitals from June 18 to September 24, 2016. The collected data were analyzed by paired t-test and Pearson's correlation coefficients using SPSS 18.0 and interdependent effect (Actor-Partner Interdependence Model analysis) through AMOS 18.0. Results: The sexual attitude and marital intimacy of the pregnant woman did not have a partner effect on the sexual satisfaction of her husband, respectively (${\beta}=.12$, p=.141), (${\beta}=.01$, p=.938). The sexual attitude of the husband had a partner effect on the sexual satisfaction of the pregnant woman (${\beta}=.13$, p=.021), but the marital intimacy of the husband did not show a partner effect (${\beta}=.07$, p=.202). Conclusion: Study suggests that the sexual attitude and marital intimacy of pregnant couples should be considered as factors when developing an intervention to improve sexual satisfaction in couples. Moreover, pregnant couples should participate in intervention together because the sexual satisfaction has conceptual view of interdependence in two-person relationships.

It is generally recognized that high stocking density can increase the risk of immune dysfunction and reduction in productivity cause of elevated stress in broiler farm. The domestic livestock industry is implementing a certification system for animal welfare and livestock farms to reduce the problem of dense breeding. This study compared broiler from the general farm and animal welfare farm to confirm the effectiveness of animal welfare farms against stress. Gas concentrations in a farm of general and animal welfare farms were analyzed, blood (n=10) of the 28-day-old broiler was collected, the partial pressure of the gas in the blood was analyzed using whole blood, and biochemical factors and hormones were analyzed using the serum. Glycogen and L-lactate are analyzed using ELISA kit on finely pulverized muscles (n=10). CO₂ and NH₃ levels in the farm were significantly higher in general farm. Partial carbon dioxide tension (PCO₂) in blood was significantly higher and partial oxygen tension (PO₂) was significantly lower in the general farm. Creatinine (CREA), glucose (GLU), aspartateaminotransferase (AST), and creatinekinase (CK) in the blood were significantly higher in the general farm, and total protein (TP) and globulin (GLOB) were significantly higher in animal welfare farm. Blood corticosterone and norepinephrine were significantly higher in general farm and epinephrine was significantly higher in animal welfare farm. These results imply that animal welfare farm provides a stress-reduced breeding environment.

김희은(Kim Hee Eun),장은정(Jang Eun Jung) 학습자중심교과교육학회 2021 학습자중심교과교육연구 Vol.21 No.5

본 연구는 대학 학습지원 프로그램 참여 학생을 대상으로 긍정심리자본, 자기결정성 동기, 학습몰입, 학습성과 간의 구조적 관계를 파악하여 학습지원 프로그램의 참여자의 특성과 성과를 확인하는 데 그 목적이 있다. 이를 위하여 2019년 12월부터 2020년 1월까지 전국의 12개 4년제 대학교 재학생 중 최근 3년간 학습지원 프로그램에 참여한 학생 324명의 설문을 분석에 사용하였으며, 연구결과는 다음과 같다. 첫째, 본 연구에서 설정한 구조적 관계에서 긍정심리자본을 제외한 모든 변인들은 학습성과에 대하여 직접적인 관계가 있었다. 긍정심리자본은 학습성과에 직접적인 영향을 주지 않는 것으로 나타났다. 둘째, 매개효과를 살펴보면 긍정심리자본은 자기결정성 동기 또는 학습몰입을 매개로 학습성과에 간접적인 영향을 주는 것으로 나타났다. 또한, 긍정심리자본은 자기결정성 동기와 학습몰입을 이중 매개하여 학습성과에 간접적인 영향을 주는 것으로 나타났다. 이를 바탕으로 개인의 내적 요인과 학습 과정에서 경험하는 요인들을 유기적으로 연계시켜 학습성과 향상을 도모하는 학습지원 프로그램의 성과를 확인하였다. The purpose of this study is to identify the structural relationship between positive psychological capital, self-determination motivation, learning flow, and learning performance for students participating in the university learning support program. For this study, the survey was used to analyze 324 students who participated in the learning support program over the past three years among 12 four-year university students nationwide, and the results of the study were as follows. First, in the structural relationships of this study, all variables, except for positive psychological capital, had a direct relationship to learning performance. Positive psychological capital is found to have no direct impact on learning performance. Second, in mediation effect, positive psychological capital indirectly affected learning performance through the mediating of self-determination motivation or learning flow. In addition, positive psychological capital had an indirect effect on learning performance by double mediating self-determination motivation and learning flow. Based on this results, it was found the performance of the learning support program improving learning performance by organically linking the inner factors of the individual with the factors experienced in the learning process. This suggests that learning support programs should be designed from an integrated and long-term perspective as well as providing learning methods.

온라인 직원 리뷰와 기업가치

김희은(Hee-Eun Kim),이한준(Hanjun Lee) 충남대학교 경영경제연구소 2021 경영경제연구 Vol.43 No.2

본 연구는 국내의 온라인 기업 리뷰 사이트인 잡플래닛(Jobplanet) 자료를 활용하여 직원만족도와 기업가치 간의 관계를 살펴본다. 2014년부터 2019년까지 한국 유가증권시장에 상장된 기업에 대해 전·현직원이 남긴 97,216건의 리뷰를 수집하여 분석한 결과, 직원만족도 평점이 기업가치(Tobin’s Q)에 유의한 양(+)의 영향을 미치는 것으로 나타났다. 이러한 결과는 직원만족도와 기업가치 간의 내생성을 통제한 2SLS(two-stage least square) 분석에서도 강건하게 나타났다. 직원만족도의 세부항목으로는 승진기회 및 가능성, 복지 및 급여, 업무와 삶의 균형, 경영진에 대한 직원만족도 평점이 높을수록 기업가치가 높게 나타났다. 연구에 강건성을 확보하기 위해 직원만족도의 대리변수로 텍스트 기반 만족도를 이용하거나, 기업가치 대리변수로 경영성과(ROA)를 이용하여도 결과는 달라지지 않았다. 본 연구는 국내에서 온라인 기업 리뷰 자료를 활용하여 직원만족도와 기업가치 관계를 살펴본 첫 번째 논문이라는데 의의를 가지며, 온라인 직원 리뷰가 기업 성과를 예측하기 위한 비재무정보로서 가치를 가진다는 것을 시사한다. Using data from online employee reviews, we investigate the association between employee satisfaction and firm value. We employ 97,216 reviews collected by Jobplanet from 2014 to 2019 and find that employer rating significantly positively impacts firm value (Tobin’s Q). We use Two-stage Least Squares (2SLS) regressions to mitigate the reverse causality issue, and our results remain unchanged. We also find that the higher employee rating related to promotion opportunities, welfare and wage, work-life balance, senior management significantly improves firm value. These results are robust based on the text-based employee satisfaction measures and firm performance measures (ROA). This is the first study of employee satisfaction on firm value using online employee reviews in Korea. Our findings suggest that online employee reviews contain value-relevant implications as non-financial information.
