This study aims to derive the implications of actor-network theory in science education research. To this end, previous studies applying the actor-network theory were analyzed. The study results show that educational research using actor-network theory can be divided into three main approaches. First, ANT was used as an epistemological perspective to construct an educational method or perspective, Second, ANT was used as an ontological perspective to recognize non-human agency, Third, ANT was used as a methodology for educational research. Based on the results, the possibility of contributing to science education research is discussed. As a new theoretical point of view, we hope that actor-network theory will be meaningful in science education practice and empirical research.

As the world becomes an aging society due to a decrease in the birth rate and an increase in life expectancy, a system for health management of the elderly population is needed. Among them, various studies on occupancy and activity types are being conducted for smart home care services for indoor health management. In this paper, we propose a random forest model that classifies activity type as well as occupancy status through indoor temperature and humidity, CO2, fine dust values and UWB radar positioning for smart home care service. The experiment measures indoor environment and occupant positioning data at 2-second intervals using three sensors that measure indoor temperature and humidity, CO2, and fine dust and two UWB radars. The measured data is divided into 80% training set data and 20% test set data after correcting outliers and missing values, and the random forest model is applied to evaluate the list of important variables, accuracy, sensitivity, and specificity.

The purpose of this study is to identify the harmful factors of teacher's job stress and occupational-related musculoskeletal diseases, and to investigate according to job types to seek solutions and improvement measures for removing harmful factors. A total of 168 elementary and high school teachers in Seoul were surveyed. As a result, the average RULA score of the teacher was 4.2 points, and the average RULA score of the teacher who did not complain of musculoskeletal diseases was 4.3 points. In addition, the average job stress score of the teacher was 58.9 points, and the stress score by factor was in the order of student guidance, work burden, loss of authority, organizational structure and curriculum, treatment and welfare, human relations. As a result of analyzing the teacher's RULA score and job stress, it was possible to derive a correlation between musculoskeletal disorders and job stress caused by occupation.

This study estimated the impact of the shock of housing price increase on the total fertility rate and the contribution of each variable to changes in the TFR. This study is differentiated by estimating the contribution rate of each variable to the fertility rate through the Shapley decomposition and the panel VAR's forecast error variance decomposition, which previous studies have not attempted. The main results of this study are as follows. First, the decline in the TFR in Korea has been strongly influenced by the recent decline in the total fertility rate, and this influence is expected to continue in the future. In the case of housing costs, in the past, housing sales prices had a relatively small contribution to changes in the total fertility rate compared to the jeonse prices, but their influence is expected to increase in the long term in the future. It has been demonstrated that private education expenses other than housing sale price and Jeonse price also acted as a major cause of the decline in the total fertility rate.

Donggang Su-ho Jo(1924-2016, hereinafter referred to as "Donggang") was a calligrapher and literarti painter who was active in recent times. When he survived, he was called the first teacher respected by all in the field of world calligraphy. His perception of beauty is due to the art view embodied by human instinct. In particular, he considered writing and painting as art of contact(接), which means connecting. Therefore, the meaning of contact(接), is recognized as a kiss between men and women or love affair(雲雨之情). In this way, his literarti painting originated from a wide range of concerns and quests for art. He recognized the principle of art creation from a universal and general perspective on beauty. Based on this, the significance of true artistic spirit and art philosophy was established. If you observe the literarti painting of the Donggang with bamboo's literati painting and orchid's literiti painting, his bamboo's literati painting has the aesthetics of lusterless(無潤), and difficulty obscurity(苦澁). His orchid's literati painting is appreciated refinement(雅) and harmony(韻) made vulgar appearance(俗). His character and scolarship became his literarti painting.

This study conducted a preliminary survey to study humanities healing methods for college students. Based on the student survey, we would like to present the research direction of humanities healing and find an appropriate humanities healing method. For quantitative analysis, 10 questions were constructed, focusing on BPS-Modell, Bio, Psycho, and Sozio of life. In the question of the Bio, 50% of the students said they understood their body, mind, and will and acted accordingly, but 20% of the students showed that their actions according to their body, mind, and will did not fit. In the question of Psycho, more than 50% of students said they communicated well with their inner selves, but less than 20% of students did not. In the question of Sozio of life, more than 60% of students form a social network well, but about 10% of students have very low attitudes or meanings toward life. The ultimate purpose of humanities is 'happiness', and the purpose of human life is also 'happiness'. We hope that the power of positivity to realize a stable future society and improve the quality of life will be expanded through humanities healing.

Positive effects such as significantly reducing traffic accidents caused by human error can be expected by the introduction of Automated vehicles (AV). However, as new traffic safety issues are expected to occur in the future due to errors in H/W or S/W of autonomous vehicles and lack of its function, it is necessary to establish a scenario to evaluate the driving safety of AV. Therefore, in this study, functional scenario was developed to evaluate the driving safety of AV based on traffic accident data of the National Police Agency. Using the GIS program, QGIS, traffic accident data that occurred in the toll gate and ramp sections of expressway were extracted and accident summary items were checked to classify the types of accident. In addition, based on the results of accident type classification, functional scenario were developed that contains various dangerous situations in the tollgate and ramp sections.

This thesis discusses a performer's unpredictability and immediacy as a prerequisite quality and/or ability to facilitate his/her professional identity as a doer on stage. To examine the key principles and approaches, this research focuses on addressing a specific aspect of the performer's transformative experience from those, directors, and practitioners' concepts that inform and enhance the performer's passive readiness on stage. To be precise, this research attempt to interrogate and articulate the place and role of a performer's internal readiness and/or that of inner looking. The performer's inner intensity as seed of action signifies that his/her body is being in a state of listening to every tiny moment with his/her heightened awareness which in turn lead the performer's body to meet the demands of theatre, the whole-body engagement. Here, this thesis argues that the key principles of acting/training underlies the importance of a performer's ethical attitude and at the same time his/her responsibility for what the performer's choices and experiences within the performative involvement, that is, a process of preparation, are not technical matter but rather, the concepts, and/or approaches from those theatre artists' practical assumptions highlight a process of thorough encountering and/or listening to his/her body. Inhabiting and/or obtaining the principles through the performer's body means being free from his/her unnecessary trait(s) which in turn initiate and then move the whole body according to what is happening in the series of moment(s) on stage. What is more, such an appropriate psychophysical order reminds us of the significance of the nature of human/performer's body, namely, to being in a state of one's 'own' body as oneness. From this perspective, this thesis further argues that the performer's body necessarily need to be affected and/or triggered in a sense of responding to the given circumstance where the performer is working on in the here and now.

The expansion of the scope of product liability is necessary because the industrial environment has changed following the enactment of the Product Liability Act. Unlike human-coded algorithms, artificial intelligence is black-boxed according to machine learning, and even developers cannot explain the results. In particular, since the cause of the problem by artificial intelligence is unknown, the responsibility is unclear, and compensation for victims is not easy. This is because software or artificial intelligence is a non-object, and its productivity is not recognized under the Product Liability Act, which is limited to movable property. As a desperate measure, productivity may be recognized if it is stored or embedded in the medium. However, it is not reasonable to apply differently depending on the medium. The EU revise the product liability guidelines that recognize product liability when artificial intelligence is included. Although compensation for victims is the value pursued by the Product Liability Act, the essence has been overlooked by focusing on productivity. Even if an accident occurs using an artificial intelligence-adopted service, however, it is desirable to present standards according to practical risks instead of unconditionally holding product responsibility.
