Objectives: This study examined ways to promote desirable eating habits by choosing foods with low sugar contents and provide nutrition education in adolescents. Methods: This study was a cross-sectional survey. The sugar reduction perception and knowledge, sugary food preference, and intake frequency of 487 male and female high school students in Incheon were analyzed comparatively. Results: Approximately 94.9% and 94.5% of the subjects were unaware of the promotion of a sugar reduction policy and the sugar reduction in the basic guidelines for school meals, respectively. Approximately 95% of them had not received any sugar reduction nutrition education, and 90% were not interested in sugar reduction. The perception for sugar reduction was significantly higher in girls (3.43 out of 5 points) than in boys (3.16 out of 5 points) (P < 0.001). Knowledge about sugar was 3.65 out of 6 points in girls and 3.04 points in boys (P < 0.001). The preference and intake frequency for fruits of the total students were 4.24 out of 5 points and 2.56, respectively. For beverages, the preference was significantly higher in boys (3.97 points) than in girls (3.70 points) (P < 0.001), and the intake frequency was significantly higher in boys (2.26 points) than in girls (2.08 points) (P < 0.001). The preference for snacks was significantly higher for girls (4.19 points) than boys (4.02 points) (P < 0.01), and the intake frequency was 2.22 points in boys and 2.17 in girls, showing no significant difference. Sugar reduction perception and knowledge about sugar showed significant negative correlations with the snack intake frequency (r = -0.11, P < 0.05; -0.13, P < 0.05) after adjusting for gender, grade, and body mass index. Conclusions: The high school students' perception of sugar reduction was very low, and there was a significant correlation with sugary food intake, suggesting that the sugary food intake will decrease as the sugar reduction perception and knowledge about sugar increase.

Given n points in the plane the planar convex hull prob-lem in that of finding which of these points belong to the perimeter of the smallest convex region (a polygon) containing all n points. Here we suggest two kinds of methods. First we present a new sequential method for constructing the pla-nar convex hull O(1.5n) time in the quadratic decision tree model. Second using the sequential method we suggest a new parallel algo-rithm which solve the planar convex hull O(1.5n/p) time on a maspar Machine (CREW-PRAM) with O(n) processors. Also when we run on a maspar Machine we achieved a 37. 156-fold speedup with 64 pro-cessor.

Thanks to the development of computer graphics, Animation can be easily accessed through movies or games. The users can meet various contents and are asking for high quality animations that resembles reality to a near perfection. The research is proceeded to observe the fish shapes and swimming movements through cyber aquariums, fish ecology museums and fish encyclopedias. The core of expressing undersea scenery is the natural and dynamic movements of the fish. In this thesis in order to achieve the natural shape of fish swimming, it is necessary to design a fish growth process system based on environmental factors and apply different standard points depending on the various swimming types of fish species to express the fish as near reality as possible. And by calculating the different swimming velocities of different standard points, a natural swimming shape will be achieved.

The purpose of this study was to analyse factors related to Home Meal Replacement (HMR) use among university students and to determine the dietary quality according to its consumption. A survey on the consumption of HMR and Nutrition Quotient (NQ) was conducted from September to November 2021. The study included 232 university students (88 males, 144 females) from Chungcheong. The proportion of consumption at least once a week was 71.55% for ready-to-eat foods, 55.60% for ready-to-cook foods, 40.95% for fresh-cut products, and 21.12% for meal-kits. The preference ratings were as follows: ready-to-eat foods, 3.77 out of 5 points, meal-kits, 3.53 points, fresh-cut products, 3.52 points, and ready-to-cook foods, 3.45 points. In terms of satisfaction, convenience (4.06 out of 5 points), taste (3.71 points), variety (3.67 points), and food hygiene (3.62 points) were rated the highest. The scores in the moderation NQ were significantly lower in the groups that consumed ready-to-eat foods (p=0.0002), ready-to-cook foods (p=0.0002), and meal-kits (p=0.0068) at least once a week compared to the groups that consumed them less than once a week. In conclusion, the results will serve as basic data for nutrition education for proper consumption of HMR among university students.

Purpose. The purpose of this study is to investigate how professional self-concept and ego-resilience of nursing students affect their clinical competence. Methods. This study conducted a structured-questionnaire survey with 143 nursing students to look into their professional self-concept, ego-resilience and clinical competence. Results. According to the study result, professional self-concept scored 2.85 on average out of 4 points, ego-resilience 3.61 on average, and clinical competence 3.48 on average. It was found that clinical competence had significantly positive correlations with professional self-concept (r=.58, p<.01) and ego-resilience (r=.44, p<.01). According to regression analysis, the factors affecting clinical competence were professional self-concept, ego-resilience, and academic grades in order, and explanatory power was 39.5%. Conclusions. Given the above results, in order to improve clinical competence of nursing students, nursing educational institutes need to find an educational plan which can contribute to increasing professional self-concept, ego-resilience, and academic grades.

Background: This study aims at making a survey on health care service providers' cultural competence and making an appraisal of Chinese medical tourists on service quality, health care service providers' cultural competence, perceived value, and satisfaction. Methods: The data was collected from August until November, 2014 and 150 health care service providers and 65 Chinese medical tourists from 12 medical institutions in Daegu were enrolled in analysis. Results: The results showed that health care service provider's knowledge on Chinese culture was very low with 33.5% of correct answer. Health care service providers were found to get 3.82 point on a 5 point-scale in cultural perception, 3.53 points in cultural sensitivity, and 2.85 points in cultural skills. Chinese medical tourists were analyzed to give 4.08 points on a 5-point scale to satisfaction on health care service, followed by 4.01 points to health care service quality, 4.00 points to perceived value of health care service, and last 3.85 points to a health care service providers' cultural skills. However, there was a difference in points in cultural skills between health care service providers and Chinese medical tourists. Chinese medical tourists' satisfaction with health care service in Daegu was found to be comparatively high, but in relation to satisfaction with communication, it was found to be relatively low. Conclusion: Through this research, health care service providers' knowledge level of Chinese culture and cultural skills were low while they seemed to take a half-hearted attitude towards educational experience for building up cultural competence and foreign patient service response.

Objectives: Whiplash injury is one of the major diseases in recent times because of increasing traffic accidents. This review aims to analyze the overall trend of studies on pharmacopuncture for whiplash injury after traffic accidents. Methods: We searched through 4 Korean electronic databases from 2001 up to October 2020 for relevant clinical studies for whiplash injury after traffic accidents, regardless of the patients' age, gender, or race. We included studies that had an intervention group receiving pharmacopuncture therapy with or without other additional treatments, and also included studies that had a control group receiving sham treatment or active treatment such as physical therapy and herbal medication. For the clinical outcomes, we did not place any restrictions on evaluation scales if they are objective metrics. Results: We included 6 randomized controlled trials (RCTs) and 10 non-randomized controlled trials (nRCTs). 10 nRCTs were divided into 4 categories that were case-control studies, case series, case report, and retrospective observational study. In RCTs, Hwangryun-haedoktang (黃蓮解毒湯) pharmacopuncture was the most frequently used. In nRCTs, Jungsong-ouhyul (中性瘀血) pharmacopuncture, and bee venom pharmacopuncture were the most frequently used. As target points of Hwangryun-haedoktang pharmacopuncture, Ashi-points, Jianjing (GB21), and Fengchi (GB20) were the most frequently used. As target points of Jungsong-ouhyul pharmacopuncture, Ashi-points were the most frequently used. And as target points of Bee venom pharmacopuncture, Fengchi (GB20) was the most frequently used. Conclusion: Hwangryun-haedoktang pharmacopuncture, bee venom pharmacopuncture, and Jungsong-ouhyul pharmacopuncture were mainly used for whiplash injury, and their usual target points were Jianjing (GB21), Fengchi (GB20), and Ashi-points. However, a high level of evidence should be conducted through studies with systematic methodology in the future.

In this paper, we present a real-time hand pose recognition method to provide an intuitive user interface through hand poses or movements without a keyboard and a mouse. For this, the areas of right and left hands are segmented from the depth camera image, and noise removal is performed. Then, the rotation angle and the centroid point of each hand area are calculated. Subsequently, a circle is expanded at regular intervals from a centroid point of the hand to detect joint points and end points of the finger by obtaining the midway points of the hand boundary crossing. Lastly, the matching between the hand information calculated previously and the hand model of previous frame is performed, and the hand model is recognized to update the hand model for the next frame. This method enables users to predict the hidden fingers through the hand model information of the previous frame using temporal coherence in consecutive frames. As a result of the experiment on various hand poses with the hidden fingers using both hands, the accuracy showed over 95% and the performance indicated over 32 fps. The proposed method can be used as a contactless input interface in presentation, advertisement, education, and game applications.

The national geodetic control point is very important as a framework for drafting plans for construction and civil engineering works as well as mapping for various development and utilization plans related to the national land. Since the 1910s, Korea has established and managed the national geodetic control points, the triangulation points and the benchmarks. Currently, these point information is provided through the land information platform. The national geodetic control point has been changed through the process of loss, re-establishment, and re-location by the events and environment of the times. Therefore, it is very important to provide information by linking these past national geodetic control points in time series. In this study, we classified the triangulation points into five groups(Japanese Government General of Korea, YUCCA Project, National Construction Institute, Past Control Point Data Sheet, and Current) by age and then suggests a method to match the same control points in each time period. Finally we also applied the proposed method to Jecheon and analyzed the results.

We examined the relative growth of Microstomus achne during early life stages of laboratory-reared larvae and juveniles. Turning points in the relative growth of preanal length and upper jaw length against total length occurred during the settlement period (11.12-19.91 mm in total length). However, turning points in the relative growth of head length and eye diameter, as compared to total length, occurred during metamorphosis (17.57-22.47 mm in total length). Our results suggest that Microstomus achne concentrates its energy on the feeding apparatus (jaw) and digestive organs (intestine) rather than sensory or neural organs (eye, head) during early larval stage growth.
