  • In Korea, the construction company has provided houses through apartment sales system. Residents have obtained a variety of information about their future house by visiting a sample house called "the model house" before they purchase home. Advanced technology such as web-based VOD or Virtual Model in recent years has gradually replaced those built environment. In 2009, the Ministry of Land, Transport and Maritime Affairs announced the restraint to the construction of sample houses. Instead, they highly recommended a Virtual Model House as an alternative solution. This study aimed to propose how to design the user-oriented virtual model house through the experiment and survey research. The 3D virtual model house of 85m$^2$ apartment was built and presented by two types (Type A: Bird's Eye View, Type B: Walk through View) on the web page. The subjects evaluated presence, spatial perception and cognition, and usability of each type after exploring them. The results are as follows. (1) The subjects' evaluation of presence showed Type B has more negative effects than Type A such as feeling dizzy or tired even if their values were not so high. (2) The subjects perceived and cognized both types of virtual model house more realistic for the expression of volume of space, the size of opening, and the arrangement of furniture than that of wall finishes and materials. (3) The usability of Type A was significantly higher than that of Type B.

  • Purpose: The purpose of this manuscript is to discuss the need for use of evidence based practice (EBP) in LTC, the current use of evidence in long term care facilities and what we know about adoption of the use of EBP in LTC. Methods: Literature review and reporting of findings from the M-TRAIN study that was a quasi-experimental design to test the effectiveness of an intervention to increase the use of EBPs for urinary incontinence and pain in 48 LTC facilities. Results: Barriers to adopting EBPs include lack of available time, lack of access to current research literature, limited critical appraisal skills, excessive literature to review, non-receptive organizational culture, limited resources, and limited decision-making authority of staff to implement change. Strategies to promote adoption of EBP include the commitment of management; the culture of the home; leadership; staff knowledge, time, and reward; and facility size, complexity, the extent that members are involved outside the facility, NH chain membership, and high level of private pay residents. Findings from the M-TRAIN add, stability of nurse leader and congruency between the leaders perception of their leadership and the staff's perception of the leadership. Conclusion: There is clear evidence of the need and the benefits to residents of LTC and to the health care system yet adoption of EBP continues to be slow and sporadic. There is also evidence for the process of establishing best evidence and many resources to find the available EBPs. The urgent need now is finding ways to best get the EBPs implemented in LTC. There is growing evidence about best methods to do this but continued research is needed. Clearly, residents in LTC deserve the best care possible and EBPs represent an important vehicle by which to do this.

  • Purpose : This study was designed 1) to compare the perception of dental professionals and lay people with respect to minor variations in maxillary anterior tooth size and alignment and their relation to the surrounding soft tissues, and 2) to evaluate the normal tooth-gingiva topographical relationships in periodontally healthy young subjects, Materials and methods : Maxillary anterior teeth were intentionally diagrammed in varying degree of deviation with respect to one of three common anterior esthetic discrepancies including variations in crown length, shape of gingival margin, and length of interproximal contact, 17 images were generated to be preferentially selected by 2 groups consisting of dental professionals and lay people (total of 740). Smiling photographs of 120 dental students who had healthy periodontium were taken and the photographic images were analyzed to be classified as 17 kinds of altered image groups. Results : The results demonstrated noticeable difference between the varying levels of discrepancy. Both group preferred gingival margin of lateral incisor to be 0.5mm lower than that of central incisor. Lay people preferred the gingival margin shape that has 2/9 horizontal component of the crown width, while dental professionals preferred the gingival margin shape that has 1/9 horizontal component of the crown width. Lay people preferred longer length of the interproximal contact (two thirds of the crown length), whereas dental professionals preferred shorter length of the interproximal contact (half of the crown length). Photographic analysis of normal esthetic gingival topography revealed 2/9 horizontal component and short length of the interproximal contact which was of the hybrid nature of the preferences shared by lay people and dental professionals. Conclusion: The results of this study show that dental professionals and lay people demonstrated significant difference in their preference of dental esthetic components, which may then influence the decision making process by dental professionals with respect to designing the anterior esthetic gingival line.

  • 정보통신기술 및 교육패러다임 변화와 맞물려 이러닝을 활용한 직업교육훈련은 그동안 몇 차례 굵직한 변화를 겪어 왔다. 이러닝을 통한 직업능력개발의 트렌드는 학습의 모바일화, 짧은 콘텐츠의 증가, 학습경험제공의 민첩성과 현장 밀착성으로 요약 가능한 가운데, 본 연구는 이러닝을 통한 직업교육훈련 대상자들의 학습동기, 교육구성요소에 대한 중요성 인식, 학습 행태에 대한 조사연구를 실시하였다. 6개 훈련기관의 4,021명이 참여한 설문조사 응답을 분석한 결과, 자발적 자기계발 차원의 학습이 회사의 직무교육차원보다 높게 나타났고, 이러닝의 구성요소 중에서는 학습내용이 가장 중요한 것으로 나타나, 기존의 형식에 치우진 교육콘텐츠 개발이나 훈련평가가 보다 내용 중심적으로 변화해야함을 시사하였다. 학습 행태측면에서도 학습장소와 시간 활용이 보다 융통적으로 변화하였고, 시간을 정해놓지 않고 틈틈이 불규칙적으로, 특정시점에 몰아서 학습하는 추세를 확인할 수 있었다.

  • 본 논문에서는 시각정보와 경험이 가상환경에서 햅틱 디바이스로 상호작용 하는데 미치는 영향에 대한 연구이다. 이를 알아보기 위해 Load-on-task를 통하여 물체의 크기와 누적된 경험이 가상환경에서 무게를 예측하고 상호작용 하는데 영향을 미친다는 사실을 확인하였다. 또 가상환경에서 물체 이동 실험을 통해 물체에 대한 정보가 다를 경우 빠르게 잘못된 정보를 보상하고 안정적인 힘 조절을 확인하였다. 위 실험을 통해 가상환경에서의 경험이 물체의 시각적인 정보보다 많은 영향을 주지만, 경험이 없는 환경의 경우 시각적인 정보가 가상환경에서 물체와의 상호작용에 크게 영향을 주는 요소라는 것을 확인하였다. 따라서 가상환경에서 정밀한 조작(로봇 수술 등)이 필요한 의 경우 실제 물체의 물성치와 시각 데이터를 기반으로 유사한 환경을 조성해야 하며, 만약 그러한 환경 조성이 어려울 시에는 충분한 사전시험을 통하여 가상환경이 가진 특성을 경험할 수 있게 준비해야 한다.

  • Several studies have revealed that information on borrower characteristics plays an important factor in approving their credit requests. Though the extent to which such characteritics are also applicable to the case of fintech lending remain uncertain. The aim of this study is, thus, to investigate the determinant factors that influence MSEs in obtaining credit through fintech lending. Here, we emphasize virtual trust in fintech lending encompasing the dimension of social network, economic attributes, and risk perception based on several indicators that are used as proxies. Primary data used in the study was gathered from an online survey to the respondents of MSEs in Java. The result of the study indicates that determinants of MSEs in obtaining credit from lender through fintech lending are statistically influenced by internet usage activities, borrowing history, loan utilization, annuity payment system, completeness of credit requirement documents and compatibility of loan size with the business need. These factors have a significant effect on credit approval because they can generate virtual trust of fintech lender to MSEs as potential borrowers. It concludes that the probability of obtaining fintech loans in accordance with their expectations are influenced by the dimensions of social network, economic attributes and risk perception.

  • Background Little is known about the sensate recovery of skin grafts over free non-neurotized muscle flaps. The aim of this study was to evaluate the sensitivity of free gracilis muscle flaps and meshed skin grafts without nerve coaptation. Methods Thirteen consecutive patients with a median age of 55 years (range, 21-70 years) who underwent lower extremity reconstruction between September 2014 and October 2016 were included. Complications, flap contour, skin perception, and sensate recovery were assessed. Results All flaps survived completely. In one patient, wound dehiscence and infection occurred 1 month after surgery. After a median follow-up of 14 months (range, 10-51 months), a satisfactory contour and skin perception were achieved. The Semmes-Weinstein (SW) monofilament test (154.8±22 g) and static two-point discrimination (2-PD) (12.6±0.7 mm) showed intermediate recovery compared to the surrounding site (41% and 76%, respectively). There was an intermediate correlation between flap size and sensate recovery (2-PD: r=0.27, P=0.36; SW test: r=0.45, P=0.12). Vibration sensation recovered to 60%, whereas thermal sensation remained poor (19% at 5℃ and 25% at 25℃). Conclusions Finer sensation could be partially restored. However, thermal sensation remained poor.

  • Purpose: This study investigated the patient safety culture (PSC), the perception of importance on patient safety management (PIPSM) and the patient safety management activities (PSMA) of care workers in nursing homes. This was a descriptive study that attempted to provide basic data for the patient safety education program of care workers. Methods: Data were collected using questionnaires and interviews from July 1 to 31 in 2020. One hundred and seventy-four care workers participated in quantitative research. The collected data were analyzed by the SPSS/WIN 25.0 program using descriptive statistics, t-test, ANOVA, Bonferroni, and Pearson's correlation. The qualitative data were collected through semi-structured, audio-recorded interviews with six representatives and six care workers from six nursing homes. Content analysis was performed to analyze the data. Results: Positive correlations were observed between PSC and PIPSM, and between PIPSM and PIPSM. Care workers' experience in patient safety management was in the following six categories: "Safety accident risk factors", "Type of safety accidents", "How to prevent safety accidents", "Effective safety management education", "Emphasis on occupational ethics of care workers", and "Needs for standard protocol" Conclusion: These findings indicate that considering the care workers' age and facility size, nurses should enhance patient safety education for care workers and establish a management activity system.

  • Impression taking is one of the most frequently performed tasks within the legal scope of dental hygienists. This study aims to compare traditional impression and digital impression taking in various aspects with dental hygienists who have experience using digital intraoral scanners. A total of 61 subjects were included in this analysis. Traditional and digital impression taking were compared, and the perception of intraoral scanners was classified into four factors through exploratory factor analysis. After a normality test of the main variables was performed, a non-parametric test was performed. In terms of the adequacy of the size of the tool inserted into the oral cavity, traditional impression taking was more positive, and there was no significant difference in the precision of impression taking, fit of the prosthesis, and time efficiency. In contrast, the digital intraoral scanner was positive in terms of reducing nausea. In the comparison between the items of the digital intraoral scanner, relatively low satisfaction was shown in terms of convenience of use. This study compared traditional impression taking based on the experience of dental hygienists using oral scanners. It is hoped that this will be one step closer to universalization. In addition, appropriate training on how to use them should be provided.
