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.

The purpose of this study was to investigate the variation of regional skin temperature with thermography during exercise. Seven men completed 82-min trials which consisted of rest, exercise of V02 max 60% and recovery period at 30±o.5°C and 60±5%RH. Changes in skin temperature due to physical activity varied, depending region of the body. The skin temperature of the chest was significantly lowered and that of the back was significantly increased after exercise period(p<0.05). There were significant negative relationship between the skin temperature of the chest and thermal comfort sensation, and positive relationship between skin temperature of the back and thermal comfort sensation(p<0.05). It would be better to keep the chest warm, and the back cool during exercise. The skin temperature changed differently on body site due to exercise, and it was influenced by blood flow, sweating and air movement This study would be meaningful in that the change of regional skin temperature during exercise was investigated consecutively with thermography. In further study, it would be more realistic to measure physiological response with functional sportswear which applies different functional fabric based on skin temperature.

This study investigated physiological and subjective responses to different types of firefighter station uniforms made with various designs and materials. Six healthy males participated in this study that consisted of 20 min of rest, 30 min of treadmill exercise, and 30 min of recovery in a hot and humid environment (34°C and 65%RH). The experimental clothing conditions were as follows. 1) a fitted T-shirt and trouser made of 100% polyester (FC-Uniform), and 2) flame retardant T-shirts made of acrylic and cotton as well as trousers with aramid and polyester, designed for overfitting (Control). There were no significant differences in the body temperature, and sweat rate between the two conditions; however, the heart rate with the FC-Uniform was significantly lower than Control (p=.025). The clothing microclimate temperature at the chest of the FC-Uniform was significantly lower than the Control (p=.037), and a difference of 1°C was maintained until the recovery was complete. There were no significant differences in the subjective responses; however, participants experienced a humidity sensation faster with FC-Uniform in the recovery phase. The results indicate that changes in the design and material of firefighter station uniforms may have a positive influence on reducing the thermal stress of firefighters.

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 ( Hee Eun Kim ) 한국치위생과학회 2013 치위생과학회지 Vol.13 No.2

Recently, there have been improvements in diagnostic methods for the assessment of early caries lesions. The reason is that dental professionals are seeking methods to reliably detect incipient dental caries and to remineralize them. This review examines the literature on principles, theoretical background, and history of the Quantitative Light-Induced Fluorescence (QLF) system (Inspektor Research Systems BV, The Netherlands). Furthermore, this paper discusses the potential application of QLF system to clinical practice for educational purpose, enabling dental hygiene students to perform oral health assessment using the QLF system. In addition, the clinical application of QLF system can motivate patients by providing additional visual information about caries and bacterial activity. The evidences on validity and reliability of the QLF system for detection of longitudinal changes in de/remineralization and caries were examined. The QLF system is capable of monitoring and quantifying mineral changes in early caries lesions. Therefore, it can be used to assess the impacts of caries preventive measures on the remineralization and reversal of the caries process. And the QLF system is a very promising equipment to assess educational effectiveness for dental hygiene students in their learning process. In conclusion, the QLF system is the most effective technology for more sensitive staging of caries and treatm.

Objectives : In most developed countries there has been a substantial decrease in the prevalence of dental caries in children of 12 years old over the past 40 years. This change in epidemiology highlights the importance of preventive management in dentistry. For successful management of early caries lesions, it is essential to detect and assess the pathological changes of dental caries. Therefore, the purpose of this study was to investigate the overview of International Caries Detection and Assessment System(ICDAS) criteria for the detection and assessment of early caries lesions by literature reviews. Methods : The author reviewed the MEDLINE search by the key words of ‘caries assessment’, ‘caries detection’, ‘caries measurement’, and ‘ICDAS’ Results : This literature review provided an overview of International Caries Detection and Assessment System(ICDAS) criteria for the detection and assessment of early caries lesions. This article showed the principles, concept, and primary caries detection criteria of the ICDAS. The ICDAS can macroscopically measure the enamel surface changes and potential histological depth of caries lesions by the surface characteristics of the teeth. The ICDAS criteria allow researchers and clinicians to choose the stage of dental caries and characteristics for assessment. Conclusions : ICDAS can be an adjunct method to clinical decision making and preventive treatment planning.

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.
