The purpose of this research was to explore life history of an elderly woman who fled from North Korea and to understand and provide interventions for female North Korean Defector. The participant of this research is an 81-year-old woman who escaped from North Korea and has lived in South Korea for over 14 years. This life history study followed the analysis of Mandel baum(1973) pointing three perspectives of life: dimensions, turnings, and adaptations. This study concluded that the participant of the research study had no protection while staying in China and North Korea and had experience of Homo Sacer. And even after arriving to South Korea the participant had to live her life with the past negative experiences in North Korea and China. Based on the research results discussions and implications were suggested.

This study was conducted to provide reference data for designing an alarm system that can help prevent the overturning of a container crane under wind load. Two methods, namely, fluid-structure interaction (FSI) analysis and windtunnel test, were adopted in this investigation. To evaluate the effect of wind load on the stability of the crane, a 50-ton-class container crane that is widely used in container terminals was adopted as the analysis model and 19 values were considered as design parameters for wind direction. First, the wind-tunnel test for the reduced-scale container crane model was performed according to the wind direction by using an Eiffel type atmospheric boundary-layer wind tunnel. Next, the FSI analysis for the real-scale container crane was conducted using ANSYS and CFX. Then, the uplift force determined from the FSI analysis was compared with that determined from the wind-tunnel test. Finally, a formula to compensate for the difference between the results of the FSI analysis and the wind-tunnel test was proposed.

The objective of this study was to develop lightweight, stretchable, tight-fit smart sportswear using the conductive yarns into the garment and demonstrating its usefulness. Sportswears with the ability to control LEDs with respect to lighting of the surrounding were developed by applying embroidery with conductive yarns to 2 types of men's T-shirts and 2 types of women's leggings pants for outdoor activities and exercise purposes. LEDs were applied to the front and back of men's T-shirts and to the rear of the waist of women's leggings. Men's T-shirts were printed where the LEDs were to be applied, and inside, they were embroidered with conductive threads on the hot-melt fabric to be attached, and then connected with LED. Women's pants were embroidered on the elastic band, in the form of a sine wave that gives it ability to stretch, and finally the elastic band was hidden inside the waistband. The operation of the light sensor in the dark provided the ability to protect joggers from night drivers or cyclists. LEDs were activated when the wearer turns on the fashionable device on his/her shoulder by pressing it. It was able to reduce the risk of accidents by giving recognizability to vehicles, bicycles, and athletes approaching or passing by at night, and securing safe distance from vehicles, etc. Internal embroidery technology had the same flexible and lightweight functions as ordinary clothing products, making it possible to apply to tight-fit smart T-shirts or leggings pants designs.

Acting is an act of expressing personality, image, sound, tempo, and movement flexibility in order to effectively express fictional characters in the play. It is said to refer to the action or mood of the person performing the character. In addition, all these acts are important elements of the media that the director wants to convey the subject of the work to the audience. In particular, the actor relies on the ambience, image and passionate role of winning and losing in theatrical film. In addition, more than 60% of the afterimages or remaining images in the film are images of the actor's acting or movement, and the trend of the actor. This study is not about acting divided by Conti, who is under the control of directors and directors. The purpose of this study is to analyze the aesthetic response and analyze the inner half of the suspense in the act and to help influence the expression that is effective in expressing the play.

This study aimed to research the local production of conductive composite yarn, a source material used in textile-type electrodes and circuits. The physical properties of an internationally available conductive composite yarn were analyzed. To manufacture the conductive composite yarn, we selected one type of conductive yarn with Ag-coated polyamide of 150d 1 ply, along with two types of polyethylene terephthalate (PET) with circular and triangular cross-sections, both with 150d 1 ply. The conductive composite yarn samples were manufactured at 250, 500, 750, and 1000 turns per meter (TPM). For both conductive composite yarn samples manufactured from two types of PET filaments, the twist contraction rate of the sample with a triangular cross-section was stable. Among the samples, the tensile strength of the sample manufactured at 750 TPM was the highest at approximately 4.1gf/d; the overall linear resistance was approximately 5.0 Ω/cm, which is within the target range. It was confirmed that the triangular cross-section sample manufactured with 750 TPM had a similar linear resistance value to the advanced product despite the increase in the number of twists. In future studies, we plan tomanufacture samples by varying the twist conditions to derive the optimal conductive yarn suitable for smartwear and smart textile manufacturing conditions.

As biennale exhibitions has been expanded into all of the world since 1990s, these trends of blockbuster exhibitions have caused several problems. For instance, some major curators monopolized most global size exhibitions despite of a variety of cultural and historical backgrounds. Besides, due to a strong connection between these curators and their own artists, the young emerging artists' opportunities tend to be reduced as a result of the power game. In addition, major curators' power have influence on the exhibition style as well as on the theme itself. Some artists who did not involved that kind of huge scale exhibitions dispute that the direction of the exhibition is concentrating on the curator's interest instead of artists or viewers. Although these dissatisfactions could not portray correctly the process of organizing and managing system of a biennale exhibition, those biennale exhibitions held in recent have shown tautologic discourses without any passion and positive attitude direct to the exploitation of our society as a vanguard. In the process of comparing several kinds of biennale exhibitions, I could find that some artists who participated several biennale exhibitions at the same time did not present their creative vision, although the triumph of an exhibition was typically measured by the amount of visitors. Thus, the aim of this article is to prove that the biennale can show us new cultural discourse as well as progressive method of understanding our times. Is biennale producing the real 'global standard'? If biennale has done it, could this global standard present upto-date paradigm for the unique exhibition system? Is biennale providing an useful opportunity for the understanding and communicating of contemporary art through the recontextualization which is pronounced by the publicity of curator and organizing committee? How can we find the distinctive strategy from each biennale exhibition including Venice Biennale? Biennale, as a blockbuster exhibition, always requires a degree of hype, otherwise it would not be a special event and would not attract a big enough audience. It is the actual reason why major biennale exhibitions seem to be similar artistic events. Unfortunately, it seems that the excess of biennale exhibitions might bring about the lack of contents. In this case, the biennale syndrome would being a kind of the center of poverty, in spite of the visual splendor. After all, following the global standard may not be a matter of great importance now. What really matters is how each biennale exhibition which started under the different conditions can search their own identity.

A significant cause of fall or overturning accidents in the construction industry, including landscaping construction and management, is work at heights using portable ladders. Portable ladders are classified as A-type or triangular support ladders depending on the number of supporting leg and support conditions. The tripod mobile ladder, which supports itself with only three supporting legs, is unstable and more prone to overturning compared to the A type ladders. Therefore, using the specifications of the tripod mobile ladder and the stability regulations of EN131-Part 7, overturning and resistance moment calculation formulas were derived for all directions in which overturning could occur. The moments calculated using these equations, and the overturning stability in each direction were evaluated. According to the calculation results, although there are differences depending on the direction, most are unstable for overturning at 8 or more steps. Based on these results, this study proposed measures to increase the moment of resistance by changing the weight, depth, and width, and using outriggers to ensure stability against the overturning of ladder. However, when changing the specifications of these measures, the size increases are excessive and the applicability is insufficient. On the other hand, outriggers are an applicable measure as they can ensure stability against overturning with only a minimum expansion length.

The height of large car and truck carriers from the keel to the wheel house is 44 ~ 46 m, and as the car-carriers increases in size, it exhibits the 'top heavy' characteristic, where the upper section is heavier than the lower section. This study aims to estimate the maximum outward heel angle of the Golden Ray car-carrier (G-ship) during turning maneuvers for accident investigation and the prevention of similar accidents. The theoretically calculated maximum outward heel is 7.5° (at 19 kn, rudder angle 35°) with a GM of +3.0 m or higher, and 16.7° with a GM of +1.85 m. Meanwhile the experimentally modified maximum outward heel is 10.5° (at 19 kn, rudder angle 35°) with a GM of +3.0 m or higher, and 23.3° with a GM of +1.85 m. The G-ship is maneuvered during an accident at a speed of 13 kn, at starboard rudder angle of 10° to 20°, it changes course from 038°(T) to 105°(T) based on the instructions of the on-board pilot. At this time, the maximum outward heel is estimated to be between 7.8° and 10.9° at the port side, which is 2.2 times higher than the normal outward heel. In the IS code, cargo ships are required to exhibit a minimum GoM of +0.15 m or more. The maneuvered G-ship exhibits a GoM of +1.72 m. It is not maneuvered because it fails to satisfy the international GoM criteria and because its GoM is insufficient to counteract the heeling moment during the maneuver. This study is performed based on accident-investigation results from the Korea Maritime Safety Tribunal and the USCG.

The purpose of this study was to investigate the research trends related to the children's department of church schools. The purpose of this study is to present basic data for the study of the children's department of church schools by analyzing the research period, research contents, research methods, and subjects of research related to the children's department of church schools. For this study, 50 domestic master's and doctoral dissertations searched through the National Assembly Library and the Research Information Sharing Service(RISS) were extracted with the keywords of 'church school' and 'children's department'. The frequency and percentage were calculated by analyzing the research related to the children's department of the church school according to four criteria: research period, research content, research method, and research subject. As a result of the study, first, the research trend of research papers in the children's department of church schools was found to be 49 articles (98%) for master's degrees and 1 article (2%) for doctoral degrees from 1980 to 2022. Trends by research period are focused on master's degrees. Second, the trend by research content was 27 practical studies (54%) and 23 theory studies (46%). In the research related to the children's department of church schools, the practical research accounted for a relatively high percentage compared to the theory research. Third, the trends by research method were in the order of 30 literature studies (60%), 19 quantitative studies (38%), and 1 qualitative study (2%). Research related to children's departments in church schools is being actively conducted with a focus on literature research. Fourth, as for the trends by study subject, the study was conducted focusing on physical subjects, with 35 subjects (70%) and 15 subjects (30%) of personal subjects. As research is conducted from physical objects to church schools and media, it is necessary to study the connection between church schools and families. As the research on church school kindergarten is focused on adults (teachers, parents, and educational preachers), in-depth research on children in church schools and qualitative research with voices from the field of children's department in church schools are required.
