한민족의 공통적인 삶의 풍속은 신분이나 계급의 구분 없이 삶의 감정을 반영하고 있다. 우리 민족만이 가지는 정서와 해학과 유머가 곁들여진 멋들어진 그림으로서의 풍속화는 우리의 역사와 함께 하며, 진실을 담아내는 그릇처럼 사실성과 기록적 성격, 도상적인 전통미를 드러내고 있다. 각각의 시대상황과 문화, 예술, 철학, 종교 등을 화면의 조화로움과 미의 세계를 구축하며 그려진 풍속화야말로 게임그래픽의 도상학적 원류로 보아도 좋을 것이다. 게임이 가상현실의 재현으로, 그 속에서 게임을 즐기는 유저들이 생활하는 또 하나의 공간으로 이해 됐을 때, 창조적인 기획력과 예술성 있는 그래픽의 개발은 반드시 필요하며, 또한 새로운 컨텐츠의 개발로서, 우리의 전통 풍속화에 대한 관심이 필요한 때이다. 풍속화에 대한 현대적인 재해석과 표현기법의 개발로, 게임그래픽 도상의 다변화를 꾀해 다양한 연령층의 유저 확보가 가능해진다면, 게임의 저변화로 게임산업 발달의 초석을 이룰 것은 자명한 일이다.

In this study, we used the 3D simulation program to create bodice patterns for adolescents boy students and analyze the fitting and air gap through 3D simulation. The purpose of this study was to select the bodice pattern method that best suited the body shapes of the adolescents male students. The subjects of this study were the French E pattern, Japanese N pattern, and Korean industrial L and J patterns. The applied size was the sixth Korean human body size survey data of 2010 Korea. The age range of the subjects was 13-18 years. DC Suite Program Ver. 5.1 was used, and SPSS 23.0 program was used for data analysis. As a result of comparing the shapes of the bodice patterns in the 3D simulation program, the E pattern had two waist darts on the front and one shoulder dart and one waist dart on the back, and the J and L patterns only had one dart on the back. The N pattern had no darts on either the front or back. As a result of examining the appearance evaluation of the pattern, air gap, color distribution, and clothing cross-section, the E pattern was evaluated as the closest to the body, and the N pattern was evaluated as the pattern with the largest allowance. The J pattern was evaluated as the best fit for body shape of the male adolescents. However, it is necessary to develop a pattern system by adding extra ease in setting the center front length.

Objective: This study aimed to analyze the correlation of horizontal and sagittal planes used in two-dimensional diagnosis with lip canting by using three-dimensional (3D) analysis. Methods: Fifty-two patients (25 men, 27 women; average age: 24 years) undergoing treatment for dentofacial deformity were enrolled. Computed tomography images were acquired, and digital imaging and communication in medicine files were reconstructed into a 3D virtual model wherein horizontal and sagittal craniofacial planes were measured. Subsequently, the correlations of lip canting with these horizontal and sagittal planes were investigated. Results: The mandibular symmetry plane, the occlusal plane, Camper's plane, the mandibular plane, Broadbent's plane, and the nasal axis plane were correlated with the amount of lip canting (Pearson's correlation coefficients: 0.761, 0.648, 0.556, 0.526, 0.438, and 0.406, respectively). Planes associated with the lower part of the face showed the strongest correlations; the strength of the correlations decreased in the midfacial and cranial regions. None of the planes showed statistically significant differences between patients with clinical lip canting (> 3°) and those without prominent lip canting. Conclusions: The findings of this study suggest that lip canting is strongly correlated with the mandibular symmetry plane, which includes menton deviation. This finding may have clinical implications with regard to the treatment of patients requiring correction of lip canting. Further studies are necessary for evaluating changes in lip canting after orthognathic surgery.

Purpose: This study compared the functional fitness and brake response of elderly and young drivers to confirm the correlation between the functional fitness and brake response. Methods: This study was a cross sectional observational design. Older drivers (>65age, n=21) and young adult drivers (20-40aged, n=20) were enrolled as subjects. The functional fitness of the subjects was measured using a senior fitness test consisting of a back scratch (BS), chair sit and reach (CSR), arm curl (AC), chair stand up (CSU), foot up and go (8-FUG), and 2-minute step (2-MS). The brake response used the virtual driving simulator to measure the brake reaction time (BRT) and braking distance (BD) according to the pedestrian protection and traffic signal compliance. Results: The older drivers had a lower BS (p<0.000), CSU (p=0.040), and 8-FUG (p=0.011) than the young adult drivers. BS and 8-FUG showed a significant positive correlation with the BRT and BD of pedestrian protection and traffic signal compliance. CSU showed a significant negative correlation with the BRT of pedestrian protection and traffic signal compliance. Conclusion: These findings suggest that the flexibility of the upper extremity, lower extremity strength, and agility are strongly correlated with the driving performance of elderly drivers.

Purpose: This study was done to examine the awareness and management practice of operating room nurses, to prevent nosocomial infection, to identify problems and to propose solutions. Method: The research tools used were the hospital infection control guideline and a modified version of the measurment tools used in the study of Cho (1998). The questionnaire consisted of questions on hand washing, personal hygiene and clothes control, cleaning and environment control, sterilizing supplies and disposal of contaminated materials. The collected data were analysed with the SPSS program. Results: The mean score for domain-specific awareness of nosocomial infection control was 4.81 out of a possible 5 points. The highest score was for sterilizing supplies and disposal of contaminated materials. The mean score for domain-specific practices of nosocomial infection control was 4.40, out of a possible 5 points. Sterilizing supplies and disposal of contaminated materials had the highest scores. The mean score for awareness in all domains was higher than mean score for practice. Among the general characteristics of the nurses, high awareness was found only in the provision of infection control guidelines and it had shown statistically significant difference. Examination of relation of general characteristics to practice showed that for age, career, the provision of infection control guidelines, and experience in infection control education there were statistically significant differences in the scores. For the relation between awareness of nosocomial infection control and practice, positive correlation was found in all domains, thus high awareness leads to high practice. Conclusion: Considering the result of this research, plans are needed that promote virtual practice of hospital infection control.

Objective: Independent walking is the most essential prerequisite to maintain quality of life in older persons. The purpose of this review was to investigate the effect of fall prevention strategies on fall risk for type 2 diabetes mellitus (T2DM) within community-dwelling older adults aged 65 and over. Design: A systematic review and meta-analysis. Methods: PubMed and three other databases were searched up to October 31st, 2018 and randomized controlled trials (RCTs) evaluating fall prevention strategies for fall risk in persons who were 65 years of age or above with T2DM were included. The review extracted the following information from each study selected: first author's surname, published year, country, study population, type of intervention, intensity of intervention, comparison, measurement variables, additional therapy, summary of results, and mean and standard deviation from selected studies. Results: This review selected fourteen RCTs with 460 older adults with diabetes mellitus. Of the 14 studies, the types of intervention used to improve the risk of falls were strengthening (5), aerobic exercises (2), multimodal exercises (4), one virtual reality exercise (1), whole body vibration with balance exercise (1), and Tai Chi exercise (1). Seven RCTs were eligible for the meta-analysis. Therapeutic interventions were more effective than the control group for the Timed Up-and-Go test (-1.11; 95% CI, -1.82 to -0.41) and the 6-minute Walk Test (-1.89; 95% CI, -8.33 to 4.54). Conclusions: The results of the review suggest that interventions to prevent fall risk in older adults with T2DM should focus on strengthening, balance, aerobic, and multimodal exercises.
