As an interest in metaverse increases, there are many studies to apply virtual reality to indirect experiences. Virtual reality is increasingly being used not only for entertainment such as games but also for educational content. A key technology of indirect experience is modeling an object to provide a realistic experience to the user. Natural environments such as tidal flats change with time, and many living things also live there. In this paper, we propose a method for creating experiential content that accurately models the ecological environment of tidal flats. The proposed method explains how to naturally model the temporal change of tidal flats. We also explain how to model a crab, a creature that inhabits the tidal flat, in the forms of an NPC using the behavior tree. Implementation results show that the proposed method uses simple algorithms but expresses the shapes of tidal flats well.

Malware has its own unique behavior characteristics, like DNA for living things. To respond APT (Advanced Persistent Threat) attacks in advance, it needs to extract behavioral characteristics from malware. To this end, it needs to do classification for each malware based on its behavioral similarity. In this paper, various similarity of Windows malware is estimated; and based on these similarity values, malware's family is predicted. The similarity measures used in this paper are as follows: 'TF-IDF cosine similarity', 'Nilsimsa similarity', 'malware function cosine similarity' and 'Jaccard similarity'. As a result, we find the prediction rate for each similarity measure is widely different. Although, there is no similarity measure which can be applied to malware classification with high accuracy, this result can be helpful to select a similarity measure to classify specific malware family.

In this study, the radiation protection effects of selenium, known as a powerful antioxidant, were studied. After 14 days of oral injection of selenium into the rat, a full body irradiation of 10 Gy was carried out. And after 1 day, 3.5 day, 7 day and 21 day, we observed blood cell components and superoxide dismutase(SOD) and small intestine changes. Compared to irradiation groups, there was a significant protection effect of reducing the hematopoietic immune system damage in the irradiated group after selenium administration(p<0.05). Then, selenium is a valid ingredient that increases the activity of the superoxide Dismutase(SOD), and it is confirmed that it has an effect of inhibiting apoptosis expression of small intestinal cells by irradiation. Based on these results, selenium is considered to be an essential ingredient for protecting living things from radiation.

This paper introduces a smart aging service that helps the elderly lead a happy old age by actively utilizing IoT and AI technologies for the elderly who are increasing rapidly as they enter the aging society. In particular, we propose a future-oriented, age-friendly well-being support system that breaks away from the existing welfare concept to solve the aging problem but leads to a paradigm shift toward building a vibrant aging society by protecting from emergency and satisfying emotions. By introducing IoT and AI, it judges the life situation and emotional state from the living information of the elderly can respond to emergencies and suggest meetings as a change of mood and give an emotional comfort. Since the proposed system uses artificial intelligence techniques to determine the degree of depression when inputting information such as pulse-rate, dangerous word usage, and external communication, I think it showed the feasibility of the new concept of wellbeing support system that is totally different from conventional wellbeing concept of health-care.

Daesoon Jinrihoe makes use of The Canonical Scripture as the main body to explain their thinking regarding divine beings and humankind as it relates to doctrine, sacredness, religiousness and other such contents. The traditional meaning of divine beings and humankind through the interpretation of The Canonical Scripture, transcends ethics, tradition, sociality, and the ultimate concern of secularity. The analysis from the perspective of The Canonical Scripture can help readers to understand the purpose of Daesoon Jinrihoe's implementation of its policies and their future direction. The local church takes the Bible as its main body and connects God with man as an implantation of divine life and temperament that harmonizes itself with human life and nature. The divine life is constantly reconciled with one's human life to make one a holy person, or a humanistic diviner. This is the rationale of the 'God-Man,' those whose human lives become lives of God-men. This style of living enables divine nature to mingle with human nature as an explicit behavioral act, mode of character development, and lifestyle. Therefore, the expression "the Blending of God and man" is an interpretation of the relationship between God and man which focuses on their sacred connection. Engagement in this extends to the scope of the local church. The different divisions between Daesoon Jinrihoe and the local church appear on the basis of things such as history, culture, language, and religion, but both posit a theology of "Harmonious Union between Divine Beings and Human Beings" and "the Blending of God and man" according to a transcendent interpretation of God and man. Through dialogue, they can discover similarities and differences in this shared notion with both systems of theological thought.

This study intends to deal with the flow of posthumanism after humanism, which views humans from the same dimension as other living things, and the problem of transhumanism, which originated from it, but on the contrary, dreams of augmented humans through science and technology. After that, this study intends to examine how the modern theory of justice can evaluate the situation about these two extremes. In particular, the guide we have chosen in relation to the theory of justice, is Michael Sandel, and by passing the problem of future post/transhumanism into this discussion, we propose how we can evaluate the flow of future anthropology from the standpoint of the traditional theory of justice. Post/transhumanism and its various events are approaching as our inevitable fate. However, along with this inevitable situation, many discussions are still needed in order to pass the theory of justice and to be accepted as valid.

Recently, the frequency and range of algae occurrence in major rivers and lakes are increasing due to the increase in water temperature due to climate change, the inflow of excessive nutrients, and changes in the river environment. Abnormal algae include green algae and red algae. Green algae is a phenomenon in which blue-green algae such as chlorophyll (Chl-a) in the water grow excessively and the color of the water changes to dark green. In this study, a 3D virtual world of digital twin was built to monitor and control water quality information measured in ecological rivers and lakes in the living environment in real time from a remote location, and a sensor measuring device for water quality information based on the Internet of Things (IOT) sensor. We propose to build a smart water environment service platform that can provide algae warning and water quality forecasting by predicting the causes and spread patterns of water pollution such as algae based on AI machine learning-based collected data analysis.

Because multiple ovulation embryo transfer (MOET) in cattle includes several benefits such as wide spreading of genetically superior offspring for long distance, this biotechnological method has been widely applied to Hanwoo. When the recipients are not stayed close after embryo recovery from donor, the embryos are moved to other farms via several vehicles (car, train, and airplane). However, air travel induces lesser oxygen level, increased vibration, lower air pressure, higher noise, and increased exposure of cosmic radiation to living things than ground level. It was still unknown that fresh embryos obtained from multiple ovulation of Hanwoo could maintain their fertility after being transported via air plane, the present case report introduced a clinical case of MOET in Hanwoo after shipping fresh embryos via air transportation. The donor was multi-ovulated via follicle-stimulating hormone series of injection, which was followed by a gonadotrophin-releasing hormone injection and artificial insemination twice. The embryos were recovered by the uterine flushing, packed in ministraws, transported to recipients for 6 h including 1 h air flight, and then transferred to the synchronized recipients. During pregnancy diagnosis of early gestation period, 5 of 7 recipients (71.4%) presented no heat signs and showed fetal sacs with fluid under transrectal ultrasonography. After normal gestation period, all recipients naturally delivered healthy calves (male n = 2 and female n = 3) without abortion, stillbirth, and premature birth. The present case report indicated that transportation of fresh embryos for MOET via domestic flight in Korea did not affect to their fertility.
