In recent years, the number of single-person elderly households has increased, but when an emergency situation occurs inside the house in the case of single-person households, it is difficult to inform the outside world. Various smart home solutions have been proposed to detect emergency situations in single-person households, but it is difficult to use video media such as home CCTV, which has problems in the privacy area. Furthermore, if only a single sensor is used to analyze the abnormal situation of the elderly in the house, accurate situational analysis is limited due to the constraint of data amount. In this paper, therefore, we propose an algorithm of abnormal situation detection fusion inside the house by fusing 2DLiDAR, dust, and voice sensors, which are closely related to everyday life while protecting privacy, based on their correlations. Moreover, this paper proves the algorithm's reliability through data collected in a real-world environment. Adnormal situations that are detectable and undetectable by the proposed algorithm are presented. This study focuses on the detection of adnormal situations in the house and will be helpful in the lives of single-household users.

The purpose of this study was to derive ethical life skills in the era of the COVID-19 pandemic from the 'care of self' that Foucault highlighted in . Care of self extends to the relationship one has with oneself and one with others. care of self is a practical ethic that realigns relationships with others and changes society through self-transformation. This study tried to derive specific practices for a life of care of self that individuals can realize against another rule of neoliberalism. Its specific practice style is keeping one's distance from dominant thoughts, forming oneself through practice and writing of subjective thinking, practicing knowing in everyday life, and practicing 'looking down'. These modes of self-care include the other and the world into consciousness in self-examination and transformation. Therefore, through care of self, individuals in the pandemic era can be reborn as members of society who change their lives while building a self-centered life that is faithful to themselves.

Nuclear power has been an attractive energy efficient and to the pressure with the climate change despite of its risks. There are safety, security, and environmental concerns with the nuclear radiation, but the techno-optimism forms the mainstream by experts and the state to be able to control and manage the risks yet occurred. The disastrous Chernobyl and Fukushima nuclear accidents brought about alternative action and thought including renewable energy expansion, efficient energy delivery and use, and enhancing stewardship to environmental carrying capacity. More significant alternative movement is sought by victims of nuclear radiation, technicians, and the general public who realized the pitfalls of expert and state centered policy formation. These laypersons become counter-expertise competent in recognizing local contamination and considering the risks and emotions seriously affecting peoples' everyday lives. They play important roles in the construction and legitimation of alternative knowledge about nuclear power widely realized across regions.

Air filters are being used in countless places from industrial sites to everyday life. The spread of the COVID-19 virus, which started in 2019, is disrupting people's daily lives, and the importance of air filters as a basic means to prevent the spread of these diseases is further highlighted. In this study, the purpose was to develop another type of air filter media with excellent barrier properties that can replace PP meltblown nonwoven fabrics widely used commercially due to its excellent electrostatic properties, differential pressure and filtration efficiency. Therefore, wet-laid nonwoven for air filters were manufactured using plexi-filaments formed through flash spinning and having various fiber diameter from hundreds of nanometers to tens of micrometers, and its applicability as an air-filter media was investigated compared to the meltblown nonwoven. As a result of the performance evaluation, it was found that the filtration efficiency and barrier performance at 0.3㎛ was superior to that of the meltblown nonwoven of the same weight, although the differential pressure was high due to morphological properties of the plexi-filament.

This article identifies the problems and substantiates the directions for the development of distance learning technologies in the training of personnel. An example of using digital media to create a remote access laboratory is given. The article is devoted to the definition of the main aspects of the organization of distance education. Rapid digitization, economic, political and social changes taking place in Ukraine necessitate the reform of the education system. First of all, it concerns meeting the educational needs of citizens throughout their lives, providing access to educational and professional training for all who have the necessary abilities and adequate training. The most effective solution to the above-mentioned problems is facilitated by distance learning. The article analyzes the essence and methods of distance learning organization, reveals the features of the use of electronic platforms for the organization of this form of education in different countries of the world. The positive characteristics of distance learning are identified, namely: extraterritoriality; savings on transport costs; the interest of modern youth in the use of information tools in everyday life; increase in the number of students; simplicity and accessibility of training; convenient consultation system; democratic relations between the student and the teacher; convenience for organizations in training their employees without interrupting their regular work; low level of payment for distance education compared to traditional education; individual learning pace; new teacher status. Among the negative features of online education, the author refers to the following problems: authentication of users during knowledge verification, calculation of the teacher's methodological load and copyright of educational materials; the high labor intensity of developing high-quality educational content and the high cost of distance learning equipment; the need to provide users with a personal computer and access to the Internet; the need to find and use effective motivation mechanisms for education seekers.

Objective : This study examines the historical changes of Ssangwha-'tang', traditional restorative medicine, to a type of tea in tea rooms(Da-bang) named Ssangwha-'cha' in the modern era in South Korea. The goal is to understand how traditional Korean medical culture has been related to the food culture of everyday life. Method : We analyzed traditional medical texts, newspaper articles and advertisements, literary works, and folk song lyrics in which Ssangwha-tang and Ssangwha-cha are mentioned. Results : Ssangwha-tang used to be mentioned as a medicine to tonify 'Yang' energy(Bo-yang) in traditional medical texts from the late Goryeo dynasty to the mid-Joseon dynasty. Since the late Joseon dynasty, it has also been prescribed for cold, as the tonifying method(Bo-beop) gradually prevailed from the royal family to the public. Since then, Ssangwha-tang has been more popular with the public, with the emergence of the patent medicine(Mae-yak) market since the Opening port period and the Colonial period. As the number of Da-bang sharply increased nationwide amid the period of the country's liberation, Ssangwha-tang has been included in the Da-bang menu served as Ssangwha-cha, corresponding to the increasing demands of the public and government policy that tends to favor traditional beverages over coffee. Conclusion : The historical process in which Sssangwha-tang, a type of herbal medicine, became also considered as tea, Ssangwha-cha, provides an example of how Korean traditional medical culture emphasizing the tonification of the body is interconnected with the daily lives of the public and food culture.

The purpose of this study is to portray the phenomena of information poverty of the families of children with developmental disabilities. The focus was especially put on investigating their information needs of everyday lives and information-seeking behaviors. The sample group includes six children with developmental disabilities and their families, mainly mothers. The investigation was conducted by the participant observation and in-depth interviews. The study found out that they sought the formal information sources such as medical specialists and special agencies first with which they were not satisfied. As a result, they rather relied on informal information sources. And the information from 'the group of families of children with developmental disabilities' was thought to be the most reliable information for them. In terms of information related behaviors, the strongest information needs were regarding the children's special education, especially to the school education, and they made effort to seek reliable information. They, however, tended to passively treat their personal concerns that are not related to their disabled children. This study found out that their information poverty is in terms of the information environment, information sources and their attitude to information, and that it comes from the external(social) factors as well as internal(individual) ones.

Haeju was home to the Hwanghae-do Provincial Office and a hub for supporting the northwestern regions of Korea. Local commerce expanded in Haeju during the late Joseon period based on its abundant resources and regional products, leading it to evolve into a large city. King Seonjo temporarily resided in Haeju while seeking refuge from the Japanese Invasions of Korea, and Yi Yi (sobriquet: Yulgok) secluded himself in Seokdam in Haeju in his later years. King Seonjo's residence in Haeju and Yi Yi's retirement there boosted interest in the city among the literati and influenced its places of scenic beauty. The development of its local history and literary achievements were documented in a wide variety of historical records and visual materials. Eight scenic views in Haeju became famous through a poem written by Seong Su-ik in the late sixteenth century. Around the mid-eighteenth century, eight new scenic views became popular. Local officials and travelers from other regions produced a vast body of prose and poetry focusing on the landscape and society of Haeju, playing a crucial role in raising awareness of its scenic attractions. Most surviving visual materials related to Haeju were created in and after the nineteenth century. Many of them illustrate both landscapes and the everyday lives of people. Among them, paintings of scenic spots created by Jeong Seon (sobriquet: Gyeomjae), who never actually visited Haeju in person, raises some of the issues posed by relying on indirect materials. In contrast, Eight Scenic Views of Haeju, which is presumed to have been produced by a local painter, appears to have accurately highlighted the characteristics of each scenic spot. Moreover, Haejudo, a folding screen presenting a panoramic view of Haeju, incorporates content from paintings depicting eight scenic views, in this case Eight Scenic views of Haeju. This practice can be observed in visual materials of other provincial cities.

In this paper, we present the results of a study of lessons learned from the life of Caleb (Cal), a significant character in John Steinbeck's "East of Eden." His life serves as a powerful example of the process of self-discovery, overcoming conflicts with self, others, and society. He emphasizes the importance of managing and understanding your emotions, learning to acknowledge and express them throughout your journey. He makes moral judgments while confronting desires and conflicts, and transparently demonstrates the importance of self-determination based on ethical decisions, while his honest expression and acceptance of his own emotions emphasizes the core value of emotion management and understanding. Additionally, his story emphasizes the clear importance of understanding and compromise in human relationships. We present a thorough exploration of these topics and consider how the lessons from Caleb's story can be applied to our everyday lives. As a result of the analysis in this paper, we expect to gain insight into how these lessons can be applied and put into practice.

Science curriculums for elementary schools were, traditionally, developed to be balanced in content and contain equal proportions of the four branches of science: physics, chemistry, biology, and earth science. To develop a successful science curriculum, we asked some questions about how elementary students recognize these branches and about what they think of the domains of science in the science curriculum. Our study was designed to investigate how elementary students classify the domains of science in the curriculum. Previous research (Lee et al., 2001) seemed not to be successful, because verbal expressions in that research might be inappropriate for elementary students who were unaccustomed to the technical language of science. For this reason, instead of using only words, we developed image card instruments, made of picture duplicates of the introductory covers of each unit in the 3$^{rd}$, 4$^{th}$, and 5$^{th}$ grades' science textbooks. We asked students to classify these cards into their own categories and record the reasons for classifying them. The ratio and distribution of the units was then analyzed to identify their view of the science domains. 30% of the 4$^{th}$ grade students created the following categories: 'nature,' 'observation,' 'seasons,' 'living things,' 'sounds,' 'separating,' and 'the things necessary for everyday life'. In the case of the 5$^{th}$ grade, over 30% created the categories of 'living things,' 'weight,' and 'water.' Over 30% of the 6$^{th}$ grade created the categories of 'nature,' 'light,' 'water,' 'living things,' 'solution,' 'fire,' 'properties of an object,' and 'experiment.' Upon scrutinizing the above results, we discovered that the science domains selected by students into three types of domains: academic contents and concepts; activities related to a science class; and lessons and experiences in students ' lives. The last category was a new, complex kind of domain. We concluded that students did not utilize the four branches of science when constructing their own domains of science. Instead, they created many alternative domains, which reflected students' thoughts of and their experiences. The educational needs of elementary students suggest that when organizing science curriculum as 25 % allocation of the four science branches, newly-created domains should be considered.
