Statistical models of shape variability based on active shape models (ASMs) have been successfully utilized to perform segmentation and recognition tasks in two-dimensional (2D) images. Three-dimensional (3D) model-based approaches are more promising than 2D approaches since they can bring in more realistic shape constraints for recognizing and delineating the object boundary. For 3D model-based approaches, however, building the 3D shape model from a training set of segmented instances of an object is a major challenge and currently it remains an open problem in building the 3D shape model, one essential step is to generate a point distribution model (PDM). Corresponding landmarks must be selected in all1 training shapes for generating PDM, and manual determination of landmark correspondences is very time-consuming, tedious, and error-prone. In this paper, we propose a novel automatic method for generating 3D statistical shape models. Given a set of training 3D shapes, we generate a 3D model by 1) building the mean shape fro]n the distance transform of the training shapes, 2) utilizing a tetrahedron method for automatically selecting landmarks on the mean shape, and 3) subsequently propagating these landmarks to each training shape via a distance labeling method. In this paper, we investigate the accuracy and compactness of the 3D model for the human liver built from 50 segmented individual CT data sets. The proposed method is very general without such assumptions and can be applied to other data sets.

A survey was carried out regarding university students' recognition of high-caffeine energy drinks in an effort to identify and improve problems as well as provide basic data. Most of the subjects had previous experience of energy drink consumption. Studies showed that most students consumed energy drinks when studying. Regarding frequency of energy drink consumption, most students' responded "1~6 times a year"; female students showed lower frequency of energy drink consumption than male students. Both male and female students used convenience stores to purchase energy drinks. In most cases, students became aware of energy drinks through advertisements on TV, radio, newspapers, and magazines. The most important factor affecting their energy drink purchase and consumption status was taste. The most frequent adverse effect they experienced after drinking an energy drink was unusual heart-pounding, whereas the biggest problem caused by energy drink consumption was addiction. This study indicates that students should have a better understanding of the problems associated with excessive and prolonged high-caffeine intake. In addition, instructions for proper purchasing and consumption of high-caffeine energy drinks should be provided as well as education and campaigns concerning symptoms caused by high-caffeine energy drink consumption so that students may refrain from excessive consumption. Further, civil organizations and the government need to devise effective measures for proper regulation of high-caffeine energy drink consumption.

A The purpose of this study was to determine the present state of the exercise rehabilitation field, promote elderly sport for all, and present a revitalization program for higher quality of life for the elderly in the coming era of the Fourth Industrial Revolution and aged society. Literature review was performed to analyze the actual conditions of the activities for elderly sport for all and the relevant field of exercise rehabilitation, analyze the elderly health and welfare and elderly sport for all programs, and present a plan for revitalizing the field of exercise rehabilitation to promote elderly sport for all. First, it is necessary to reinforce the awareness and promotion of the need and importance of exercise rehabilitation in inducing seniors to participate in sport for all. Second, it is necessary to make it compulsory to place sport leaders for seniors at such places as elderly leisure and welfare centers and promote expertise in managing elderly health guidance efficiently through cooperation with welfare workers. Third, it is necessary to make it compulsory to take exercise rehabilitation and similar subjects in the curriculums of sport for all, elderly sport welfare, and silver welfare sport as well as the subject of volunteering activities at such places as elderly leisure and welfare centers with the aim of giving opportunities for career choice. Fourth, it is necessary to develop characterized exercise rehabilitation programs at senior welfare centers, community centers for the elderly, and elderly classes and employ experts equipped with exercise event and exercise rehabilitation capabilities as itinerant lecturers to contribute to the government's job creation policies through cooperation between the Ministry of Culture, Sports, and Tourism (MOCST) and the Ministry of Health and Welfare (MOHW). Fifth, it is necessary to make a greater investment in research and development required for elderly sport for all. Sixth, it is necessary to develop and distribute various exercise rehabilitation treatment videos and guidelines that seniors can use for themselves. This is associated with the fifth one; in particular, it is urgent to devise measures against Coronavirus 19. Seventh, it is necessary to reduce inefficiency and budget waste caused by overlapped tasks by establishing a new elderly sports promotion organization through adjustment by MOCST and MOHW; it is also necessary to increase the functions of organization establishment with the aim of reinforcing the education area, which involves post-retirement health care, exercise rehabilitation, safety accident prevention, and virus.
