As the market for life friendly ICT (Information and Communication Technologies) services has grown up, high tech elevator with IoT (Internet of Things), a key area of the fourth industry, have become an indispensable part of life. Existing elevators are composed of up and down buttons to conveniently climb up and down high rise buildings, but there is a small inconvenience that everyone experiences depending on the characteristics of the user's composition, types of use, frequency, etc. Existing elevators are automatically closed if there are no people within the range of sensors, but they are inconvenient for the passengers with disabilities to carry luggage or to use. In this paper, the smart button, a hardware firmware device, was designed to relieve user inconvenience by opening the elevator for a certain period of time considering the boarding time of the passengers.

This study attempted to classify the types of perceptions of the new Hanbok, focusing on female college students in their 20s, and to analyze the characteristics of each type. This study was conducted with the Q methodology and analyzed with the QUANL pc program. The perceptions of the new Hanbok among female college students in their 20s were classified into four types: Type 1: modern/practical, Type 2: convenient/practical, Type 3: temporary/accessible, and Type 4: convenient/traditional. Type 1 emphasized the selection of Western clothing fabric, matching zipper/buttons, and achromatic colors. Type 2 highlighted a design that can be worn as daily clothing by combining materials that are convenient for laundering. Type 3 stressed the operation of new Hanbok rental stores so that it is easy to access and accept new Hanboks in old palaces and Hanok villages. Type 4 required the development of a design that reflects the elements of the traditional Hanbok and is convenient for activity and laundering.

The purpose of this study was to develop a compression inner layer (CIL) that can be attached to dress shirts for men who have gynecomastia (male breast enlargement). For this, we developed shirts with CIL prototypes based on the functional, expressive, and aesthetic (FEA) consumer needs model. The user-centered design principle guided the design process. Based on size measurements, in-depth interviews, and an online survey, the design requirements for dress shirts with a CIL were determined, and the prototype was developed. The dress shirts were constructed of polyester and spandex mixed materials, while the CIL was made of thin mesh fabric knitted from 80% polyester and 20% spandex. A CIL prototype was developed with a front zipper fastening to hold the upper body tight and compress the breast area. The CIL was attached by connecting a strap with snap buttons to loops sewn into the shoulder line of the dress shirt. In the trial and sensory test, the prototype helped breast size decrease while meeting target consumer needs. The outcomes of this study provide necessary insights to develop garments for gynecomastia patients.

This study investigated 3.50 million Facebook reactions collected from 9,429 Bangladeshi news items about rape shared on social media from 2016 to 2021. The primary aim of this study was to understand users' different reaction patterns based on the five major Facebook reactions (i.e., love, haha, wow, sad, and angry). Based on the theories of emotion, we quantitatively answer one research question: How do social media users react to rape with the five major Facebook reactions? The results suggest that users are more likely to express disdain toward rape and sympathy toward the victims using Facebook reactions by using the angry button, along with the sad button. In rape news, both reactions are consistent and maintain a strong positive correlation, meaning they increase and decrease together. Although many users tend to mock and laugh at rape incidents and the victims, trend lines suggest that such expressions may not be consistent with time. Despite contextual relevance, we presume that in socially and morally unacceptable events like rape and war, the valences of reactions alter to some extent: angry and sad usually become positive, while love, wow, and haha become negative. Some strengths and limitations of the study are discussed as well.

Having pet is one of the activities people living in modern society do to relieve stress and find peace of mind. Currently, the object of companion animals has moved beyond being a real 'living entity' and has developed to a stage where the animal's upbringing process can be enjoyed in a virtual space by being programmed in digital content. This paper studies detailed elements such as character design, interaction, and realism of 'Tamagotchi (1996)', which can be said to be the beginning of digital training content, and 'Peridot (2023)', a recently introduced augmented reality-based training content. The point was that it was training content using portable electronic devices. However, while the environment in the electronic device in which Tamagotchi's character exists was a simple black and white screen, the environment in which Peridot's character operates has been changed to the real world projected on the screen based on augmented reality. Mutual communication with characters in Tamagotchi remained a response to pressing buttons, but in Peridot, it has advanced to the point where you can pet the characters by touching the smartphone screen. In addition, through object and step recognition, it was confirmed that the sense of reality had become more realistic, with toys thrown by users on the screen bouncing off real objects. We hope that this research material will serve as a useful reference for the development of digital training content to be developed in the near future.

Theoretical framework of motor learning is used to enhance perceptual motor skill in physical therapy intervention, which can be subdivided into two main types-explicit and implicit. The purpose of this study was to examine whether stroke patients with unilateral brain damage learn implicitly a motor skill using the arm ipsilateral to the damaged hemisphere. Speculation then followed as to the formation of therapeutic plans and instructions provided to patients with stroke. 20 patients with stroke and 20 normal participants were recruited. All the subjects practiced serial reaction time tasks for 30 minutes a day and retention tests on the following day. The tasks and tests involved pressing the corresponding buttons to 4 colored circles presented on a computer screen as quickly and accurately as possible. Patients with stroke responded more slowly than controls. However, both groups showed decreased reaction time in the experimental and retention periods. Also, there was no significant difference between both groups regarding explicit knowledge of consecutive order. Therefore, patients with stoke had the ability to learn implicitly a perceptual motor skill. Prescriptive instruction using implicit and explicit feedback may be beneficial for motor skill learning in physical therapy intervention for patients with brain damage.

This study was to investigate the reused possibility of zirconia reinforced glass-ceramic(IPS Empress Cosmo ceramic) with sprue button in the flexure strength and fracture toughness. 40 disk-shaped ceramic specimens (20 specimens: as-pressed material; 20 specimens: reused material) with approximately 1.7 mm thickness and 15 mm diameter were prepared by "lost wax" technique. The remnants(sprue buttons) were used for repressing. The surface treatments for the discs were gradually abraded with 320, 800, 1200, and 2000 grit SiC sandpaper. The specimens were evaluated their flexure strength with the biaxial flexure jig(ball-on-three balls) and their fracture toughness with Vickers Indentation-microfracture test. The Weibull moduli were calculated for biaxial flexural strength. The mean flexure strength and fracture toughness of each group were $122.2{\pm}18.3MPa$, $1.00{\pm}0.09MPa{\cdot}m^{0.5}$ (as-pressed ceramics), and $122.2{\pm}20.3MPa$, $1.01{\pm}0.10MPa{\cdot}m^{0.5}$ (reused ceramics). There were no significant differences in the strength and the fracture toughness between the as-pressed and the reused IPS Empress Cosmo ceramic (P>0.05). This implied zirconia reinforced glass-ceramic(IPS Empress Cosmo ceramic) could be used one more time by reusing of sprue button in the flexure strength and fracture toughness.

The wing-body trucks are special vehicles that are designed to provide large carrying space and to protect the freights from outside impacts and bad weather. They are constructed to the structure opening and shutting three-layered aluminum top. In the middle- and large-size(above one-ton) wing-body trucks, wing-body is opened/closed by opening and shutting device of oil pressure type. But one-ton truck is constructed that its wing-body is opened/closed in manual to use helping of stay-dampers. So, we developed an electronic opening and shutting device for one-ton wing-body trucks to improve the inconvenience of usage for manually operated wing-body. The developed device is consisted of two connected links and a dc motor combined with an worm gear. The worm gear changes the rotation axis of the dc motor to a right-angled direction and transfers the torque of dc motor to the links. The two connected links open/shut the wing-body using the torque transferred from the dc motor. When the wing-body starts to be opened, the biggest torque is required from the dc motor for opening the wing-body. And as the wing-body is opened more and more, the required torque is smaller for opening the wing-body. Thus, the structure of two connected links are designed to locate at the center of worm gear so that maximum torque of the dc motor is transferred the links at the initial time starting to open wing-body. The controller of the device with open and closed buttons also is designed to protect the device from over-opening and over shutting operations. The developed device is accomplished for many experiments using actual vehicle. Those experiments show that the device has more excellent performance than the oil pressure type.

The purpose of this study was to validate self care outcomes included Nursing Outcomes Classification(NOC) developed by Johnson and Maas at the University of Iowa. A sample of 103 nurse experts working in university affiliated hospitals participated in this study. They were asked to rate indicators that examplified the outcomes on a scale of 1(indicator is not at all characteristic) to 5(indicator is very characteristic). A questionnaire with an adaptation of Fehring's methodology was used to establish the content validity of outcomes. The results were as follows : 1. All indicators were considered to be 'supporting' and no indicators were considered to be 'nonsupporting'. 2. 'Self care: Toileting' attained an OCV score of 0.884 and was the highest OCV score among self care outcomes. 3. 'Self care: Oral Hygiene' attained an OCV score of 0.756 and was the lowest OCV score among self care outcomes. 4. 'Self-care: Activities of Daily Living (ADL)' attained an OCV score of 0.845 and the highest indicator was 'eating'. 5. 'Self-care: Bathing' attained an OCV score of 0.810 and the highest indicator was 'washes body'. 6. 'Self-care: Dressing' attained an OCV score of 0.831 and the highest indicator was 'buttons clothing'. 7. 'Self-care: Eating' attained an OCV score of 0.815 and the highest indicator was 'chews food'. 8. 'Self-care: Grooming' attained an OCV score of 0.833 and the highest indicator was 'combs or brushes hair'. 9. 'Self-care: Hygiene' attained an OCV score of 0.823 and the highest indicator was 'washes hands'. 10. 'Self-care: Insrumental Activities of Daily Living(IADL)' attained an OCV score of 0.776 and the highest indicator was 'uses telephones'. 11. 'Self-care: Non-Parenteral Medication' attained an OCV score of 0.796 and the highest indicator was 'identifies medication'. 12. 'Self-care: Parenteral Medication attained an OCV score of 0.810 and the highest indicator were 'identifies medication' and 'administers medication correctly'. More outcomes need to be validated and outcomes sensitive to Korean culture need to be developed.
