A cold roll-bonding (CRB) process is applied to study the mechanical properties of the roll-bonded multi-layer Al sheets. The various commercial Al sheets with a thickness of 2 mm are stacked alternately to each other from two to four layers, and roll-bonded by multi-pass cold rolling. The roll-bonded Al sheets are then conducted by annealing and/or age treatment. The as roll-bonded Al sheets...

Assessing the activity or fatigue level of muscles involved in specific tasks and acting appropriately can help prevent musculoskeletal disorders. The purpose of this study is to develop a soft...
Despite many advantages of the superhydrophobic surface, its real-world application has a huge challenge because the surface is susceptible to physical damage and other types of fluid contamination, such as oil and blood, causing a permanent loss of superhydrophobicity. Various strategies have been suggested to address the problem. However, most of the studies mainly focus on a wear-resistant...
The development of technologies to determine and control the quality of food has always been of great interest, as the freshness of food is directly related to our health. Especially in the recent coronavirus pandemic, the interest in health has increased dramatically, and as it has become common to receive food deliveries in quarantine, there has been a lot of investment in food freshness...
III-V quantum dots (QDs) act as naturally bright and highly efficient quantum emitters that can generate deterministic single or entangled photon pairs. QDs embedded in a free-standing nanowire (NW) serve as a scalable platform for site-selective and geometry-controlled in-situ heterogeneous integration onto photonic waveguides (WG) - a crucial milestone for the realization of a quantum...
Engineered living materials (ELMs) are an emerging class of functional materials, often fabricated by incorporating living cells within an inert polymer matrix to form desired functions. Unraveling the formation, spatial localization, and behavior of cellular populations within an artificial niche is a prerequisite for predicting and intensifying the functions of living materials. This study...
Clostridium ljungdahlii is a known electro-active bacteria, which can utilize solid electron donors such as negatively charged electrodes and metallic iron [1]. C. ljungdahlii also can fix CO2 and CO using Wood-Ljungdahl pathway to produce aceate, ethanol, lactate, and 2,3-butanediol [2]. These versatile capabilities of C. ljungdahlii draw attention for industrial application of mitigating CO2...
This study aims to develop an in-home senior healthcare platform that can consistently and accurately monitor and manage the life-logs of homebound seniors during their daily lives, without requiring any specific operation from them. The platform utilizes vision sensors to measure the seniors' daily behaviors and analyze the data to identify their health status. By proactively managing their...
Beyond-fifth-generation (B5G), sixth-generation (6G) and Internet-of- Things (IoT) applications, such as autonomous driving and robot-assisted living anticipate scenarios where multiple user equipment (UE) not only communicate with multiple access points (APs), but also collaborate among themselves and utilise communication signals in the detection and identification of objects in the...
Typical farming tasks and farm environments are technically challenging for automated robots to replace labor. Successfully implementing automation in agriculture is challenging because there are many technical variables that vary from country to country, region to region, and crop to crop, and it is difficult to make it economically viable.
It is difficult to develop agricultural...
This study proposes a new strategy for developing anti-glycolytic polymeric materials that can regulate energy production in cancer cells through the inhibition of aerobic glycolysis. Cancer cells suffer from energy deficiency when compared with that of normal cells; this is mainly caused by hypoxia stress and critical damage to mitochondrial respiration in cells, referred to as the Warburg...
Chemical weapons were designed to kill large numbers of people in warfare, Unfortunately, they have been often used to terrorize people even in peace, not only in war. Especially, nerve gas agents such as sarin, VX, soman, and tabun are of great concern due to their odorless and colorless characteristics. Thus, intensive research has been carried out to develop sensitive, selective, and...
Background: Previous human trials failed to support the anticarcinogenic effect of vitamin E despite biological plausibility and considerable epidemiological evidence. One of the explanations for this inconsistency was the interactive effect of the catechol-O-methyltransferase (COMT) gene and supplemental vitamin E on cancer (1). We examined whether a COMT gene variant modulates the effect...
Depression is a common mental health problem in modern society, which causes patients to lose interest and motivation in everyday activities. With the influence of social distancing measures due to COVID-19, social isolation and uncertainty have increased, leading to mental health issues such as depression and anxiety[1]. Currently, South Korea has the highest suicide rate among OECD countries...

Obesity can promote a variety of adult diseases. It can be difficult for people in this group to even start exercising. Develop a game to help people in this group get into the habit of exercising more easily.
The definition of a morbidly obese person is someone who has been determined to be morbidly obese by a clinic center. -
The importance of research
Obesity is the...
(Overview and Significance of the Study)
Infant language development[1] accelerates rapidly between the ages of 5 and 7. The ability to accurately communicate one's intentions is a necessary component of interpersonal relationships and social interaction. According to KOSIS[2], in 2020, approximately 15.4% of children aged 0-9 years had a pronunciation disorder (articulation disorder)....
Dementia[1] refers to a clinical syndrome where cognitive functions such as memory, language, and judgment gradually decline, leading to an inability to perform daily activities properly. The cause of dementia includes all conditions that can cause overall brain dysfunction. It is a disorder in which numerous nerve cells in the brain degenerate, brain tissue is lost, and the brain shrinks....
Depression is a complex mental disorder that can be triggered by various mental stresses resulting from negative experiences. It has a significant impact on quality of life and is known to even lead to suicidal impulses. [2] Previous studies have confirmed the association between vitamin D and depression, which has shown a high incidence rate worldwide after the COVID-19 pandemic. In...
Obsessive-compulsive disorder is known for characteristics of repetitive-intrusive obsessive thought and persistent-repetitive behaviors that are intended to neutralize thoughts in order to reduce anxiety.
[1] The lifetime prevalence of obsessive-compulsive disorder is 2-3%. Obsessive-compulsive disorder is known to make patients waste time, cause severe distress, and impair their...
To safeguard the increasingly deteriorating environment, the Life Cycle Assessment (LCA) has been introduced as a tool to identify the underlying environmental factors and suggest better solutions. However, the conventional LCA methodology has clear limitations as it is only suitable for static situations. In other words, the current methodology cannot cover a significant portion of ships...
Waterborne transport constitutes a significant proportion of greenhouse gas (GHG) emissions in the European Union (EU), and with growing demand, this figure continues to rise. In alignment with the European Green Deal Strategy, a substantial reduction of 90% in emissions by 2050 is targeted, necessitating the adoption of more sustainable and cleaner alternatives that are accessible,...
Obesity is one of the main causes of a chronic disease. National obesity population is increasing year by year, and due to Covid-19, physical activity is decreased and food intake is increased by 40%[1]. Physical activity such as exercise is more efficient when doing with other than doing alone[2][3], so we planned this project to effectively prevent and treat obesity through cooperative...
The marine ecosystem is threatened by rapidly changing climate change. Coral plays an important role in this marine ecosystem, such as providing shelter, food, and a place for reproduction of other marine life. In this regard, basic studies necessary for the preservation of coral living in Korea are insufficient, and studies related to larvae, the initial stage of occurrence of coral, are more...
