As a new trend in the development of urban public spaces, the use of right-angle LED screens perfectly combines building facades with naked-eye 3D visual effects, providing designers with a brand-new creative platform. How to create a realistic naked-eye 3D effect on a right-angle LED screen and bring an immersive visual experience to the audience has become a question worth exploring. So far, production companies have yet to announce the relevant design ideas and complete production methods. In order to explore the production principle and production process of the naked-eye 3D effect of the right-angle LED screen, we summarize the basic production principle of the naked-eye 3D impact of the right-angle LED screen through case analysis. Based on understanding the production principle, the actual case production test was carried out, and a complete production process of the naked eye 3D visual effect of the right-angle led screen was tried to be provided by off-line rendering. For the problem of how to deal with image deformation, we provide two production methods: post-production software correction and UV mapping. Among them, the UV mapping method is more efficient and convenient. Referring to this paper can help designers quickly understand the production principle of the naked eye 3D effect of right-angle LED screens. The production process proposed in this paper can provide a reference for production method for related project producers.

In this paper, we propose an access control system using cryptography as a method to protect personal data in public blockchain. The proposed system is designed to encrypt data according to the access policy, store it in the blockchain, and decrypt only the person who satisfy the access policy. In order to improve performance and scalability, an encryption mechanism is implemented outside the blockchain. Therefore, data access performance could be preserved while cryptographic operations executed Furthermore it can also improve the scalability by adding new access control modules while preserving the current configuration of blockchain network. The encryption scheme is based on the attribute-based encryption (ABE). However, unlike the traditional ABE, the "retention period", is incorporated into the access structure to ensure the right to be forgotten. In addition, symmetric key cryptograpic algorithms are used for the performance of ABE. We implemented the proposed system in a public blockchain and conducted the performance evaluation.

The aim of this study is to examine children's desires in a toy library and what they want to do there in order to reflect their opinions on constructing a toy library in a child care center. The study has been conducted by participatory observation on a 'toy library' project consisting of 20 five-year-olds attending B public child care center in Seoul. Observational notes were taken with voice and video recordings. The results of analysis on collected data are as follows. First, the children wanted to call the toy library a toy playground because a toy library is not for study but for play and they wanted space for rest and display with no surveillance camera. Second, they wanted to play freely without any interruption, even leaving things scattered and also wanted to play with parents and friends. Discussion followed in the view of children's right to play and to express their opinions.

This study focused on investigating the future medicine and health care industry paradigm shift and suggesting the right direction for the medical education system in order for students to be better prepared in the near future. Here, I will discuss four issues related to the future of medicine: Health 2.0, digital health, personalized medicine, and innovations of the public healthcare system. Every issue has lessons for medical education and teaching for students who major in health professions. However, it is obvious that the present is an important period of time as, currently, we are at an early stage in the future health care environment. Recently, there have been rapid transformations in various fields of medicine. Therefore, if we fail to lead medical education in the right direction, medical students will suffer from major problems in coping with these changes.

Purpose: The purpose of this study was to examine the relationship between the toothpaste squeezing methods and the amount of toothpaste that the daycare teachers apply for the children in order to prevent the overuse of fluoride-containing toothpaste among children, and to understand their educational experiences on oral health and their awareness of the right amount of toothpaste used. Methods: The subjects in this study were 87 teachers at 16 different daycare centers in the city of Sokcho, Gangwon Province. They were interviewed to find out whether they had ever received oral health education and whether they were cognizant of the right amount of toothpaste to be used. And a transverse technique and a pea-sized squeezing technique were selected to look for connections between their toothpaste squeezing methods and the amount of toothpaste used by them. Results: 89.7 percent of the daycare teachers investigated taught to preschoolers how to do toothbrushing after they took meals and had a snack. 36.8 percent of the daycare teachers had children squeeze toothpaste on their own. The amount of toothpaste applied by the daycare teachers at a time was 0.58ｇ. When they utilized two other squeezing methods, transverse technique and pea-sized squeezing technique, they used each 0.38 g (p<0.005) and 0.38 g (p=0.405) of toothpaste. Conclusion: To prevent children from being overly exposed to fluoride-containing toothpaste, daycare teachers should learn about the right amount of toothpaste to be used when oral health education is provided, and the transverse technique should be recommended to ensure the use of the proper amount of toothpaste.

Purpose: The traditional ethical study only suggests a blurred insight on the research using medical big data, especially in this rapid-changing and demanding environment which is called "4th Industry Revolution." Current institutional/ethical issues in big data research need to approach with the thoughtful insight of past ethical study reflecting the understanding of present conditions of this study. This study aims to examine the ethical issues that are emerging in recent health care big data research. So, this study aims to survey the public perceptions on of health care big data as part of the process of public discourse and the acceptance of the utility and provision of big data research as a subject of health care information. In addition, the emerging ethical challenges and how to comply with ethical principles in accordance with principles of the Belmont report will be discussed. Methods: Survey was conducted from June 3th August to 6th September 2020. The online survey was conducted through voluntary participation through Internet users. A total of 319 people who completed the survey (±5.49%P [95% confidence level] were analyzed. Results: In the area of the public's perspective, the survey showed that the medical information is useful for new medical development, but it is also necessary to obtain consents from subjects in order to use that medical information for various research purposes. In addition, many people were more concerned about the possibility of re-identifying personal information in medical big data. Therefore, they mentioned the necessity of transparency and privacy protection in the use of medical information. Conclusion: Big data on medical care is a core resource for the development of medicine directly related to human life, and it is necessary to open up medical data in order to realize the public good. But the ethical principles should not be overlooked. The right to self-determination must be guaranteed by means of clear, diverse consent or withdrawal of subjects, and processed in a lawful, fair and transparent manner in the processing of personal information. In addition, scientific and ethical validity of medical big data research is indispensable. Such ethical healthcare data is the only key that will lead to innovation in the future.

Objectives : This is the study to understand of the pulse wave factor according to BMI and period of sterility on female, and to confirm the relationship of pulse wave factor among left and right inch, bar and cubit. Methods : The Questions and measurement of the pulse wave were operated with subjects(76 sterile females using on public health center). The measurement of the pulse wave was operated in 6 part of left and right inch, bar and cubit. The pulse wave was prior measured in part of left bar (i.e. interior pulsation part of radial process styloides in left hand), and next was measured in part of left inch and bar. And the pulse wave was operated samely in part of right inch, bar and cubit. Results : The results were as follows. The pulse energy of 6 part of left and right inch, bar and cubit was showed statistical significance and decreased in order of left inch, right inch, left cubit, right cubit, left inch, right bar. The left and right inch and cubit were showed numerical value of normal range, but left and right bar were showed lower pulse eneregy than normal range. Also left and right cubit were showed lower than left and right inch, and higher than left and right bar. In BMI, The pulse energy of left and right inch, cubit and the average of right hand was not showed statistical significance in the range of low-weight, normal, over-weight and obesity. But in the left and right bar and the average of left hand, the pulse energy of over-weight and obesity group were showed significantly higher than low-weight group. And the pulse wave factor was divided the pattern of h1 showing high numerical value in inch (Ap, As, Aw) and the pattern of Wm showing high numerical value in bar and cubit (RAI, Ad) Conclusions : The low pulse energy of bar was significant observation on the setting of oriental medical diagnostic index on sterilitas.

Corporation had been made by important action rule of business ethics that observes legal standard that is prescribed in each class of administration activity. But it does not keep ethicality of corporation action that conforms law. Law can not include all parts of business ethics because it is forcing essential class for public order preservation and public welfare in right. Moreover, partial corporations are doing to justify unethical action of other evasion of taxes, consultation, manufacturing etc. with legal basis meaning abusing legal standard. For these reason, Insistence that is in point of legal standard and ethical standard is not different each other that is in equal viewpoint is brought.
