Pectin is a natural polysaccharide and biopolymer that serves as a structural component of plant tissues' primary cell walls. Pectin is primarily composed of D-galacturonic acid linked by α-1, 4-glycosidic linkage and is further classified by the ratio of esterified galacturonic acid groups known as degree of esterification (DE). Pectin that contains more than half of its carboxylate units as methyl esters is known as a high methyl (HM) ester. Conversely, pectin that has less than half of its carboxylate units as methyl esters is known as a low methyl (LM) ester. Pectin has various bioactive properties, including anticancer, anti-inflammatory, antioxidant, antidiabetic, anticholesterol, antitumoral, and chemopreventive properties. Moreover, pectin is a useful biopolymer in biomedical applications. Biomedical engineering, which is founded on research aimed to improve the quality of life using new materials and technologies, is typically classified according to the use of hydrogels, nanofiber mats, and nanoparticles. This paper reviews the progress of recent research into pectin-based biomedical applications and the potential future biomedical applications of marine-derived pectin.

This study investigated that customer satisfaction based on the effects of perceived value (innovative value, practical value, symbolic value) and innovation characteristics (innovative resistance, visibility) of wearable healthcare device users on purchase attitude. A survey was conducted on actual users who are currently using wearable healthcare devices, and the final 201 copies were analyzed using SPSS 25 and SmartPLS 3.0. The summary of research results is following here. First, it was found that the perceived values, innovative and practical values had a positive (+) effect on the user's purchasing attitude, while symbolic values did not affect the user's purchasing attitude. Second, among the innovation characteristics, innovation resistance was came out negative (-) effect on the user's purchasing attitude, and among the innovation characteristics, visibility did not affect the user's purchasing attitude. Third, it was found that perceived price had a positive (+) effect on the user's purchase attitude. Fourth, it was clarified that the perceived price and purchase attitude had a positive (+) effect on the user's customer satisfaction. Based on these research results, theoretical, practical, and future research directions were proposed.

Recently, there have been many research on fever management using u-healthcare technology. Especially, fever of infants requires continuous monitoring of body temperature by parents. For infants between 4 weeks and under 5 years old, it is recommended to use an electronic thermometer or chemical thermometer in the axilla, or to use an infrared thermometer. However, in order to overcome the reality of not being able to waste significant time on continuous monitoring, there have been demands of patch type thermometers with the internet of things (IoT) and wireless communication technologies. Existing IoT thermometers are difficult to attach to infants' body because they do not take into account its size, and their interoperability is not guaranteed because they do not comply with standards in communication. Therefore, in this study, a patch-type thermometer with a diameter of 20 mm and a weight of 2.9 g was developed to manage the fever of infants, while it communicates wirelessly with Bluetooth Low Energy (BLE) communication protocol and complies with IEEE 11073 PHD(Personal Health Device) at the same time. We verified its performance under the requirements of thermometers regulated by the Korean Ministry of Food and Drug Safety.

The global market for medical devices is huge, and it will continue showing remarkable growth in the future. However, due to the entry barrier to develop medical devices, many domestic companies have technical problems in entering the medical device industry. In this paper, we introduce an open platform that can help with research and development for companies in the healthcare industry. This open platform consists of a hardware part and a software part. A hardware part is combined into CPU, base and other modules that are easy to replace and assemble. A software part is based on application software for development developed by Bionet. We test the performance of the open medical device platform using a biosignal processing algorithm.

As social problems including aging, depopulation, healthcare, poverty, a lot of government, organizations is trying to solve the problems. Recently, social innovation is emerging as strategy for solving social problems around the world. Social innovation means more effective, sustainable and new solutions that increase total values of society. This study attempts to introduce microworks of the Samasource as a case of the business-community innovation model using IT. Samasource is one of three social ventures under the nonprofit organization Sama Group established in 2008. Its mission is to alleviate worldwide poverty by connecting unemployed people in impoverished countries to digital work. Based on the internet model "microwork", they split huge digital projects into small scales, and deliver them to BOP(Bottom Of Pyramid) groups through the internet. This case describes a business model, revenue model, and impact of Samasource's Microwork. Implications of the case were suggested in the conclusion. To this end, I would like to provide a meaningful implication to researchers and founders of the South Korea.

Background/Aims: Colonoscopy is the gold standard diagnostic method for colorectal neoplasia, allowing detection and resection of adenomatous polyps; however, significant proportions of adenomas are missed. Computer-aided detection (CADe) systems in endoscopy are currently available to help identify lesions. Diminutive (≤5 mm) and nonpedunculated polyps are most commonly missed. This meta-analysis aimed to assess whether CADe systems can improve the real-time detection of these commonly missed lesions. Methods: A comprehensive literature search was performed. Randomized controlled trials evaluating CADe systems categorized by morphology and lesion size were included. The mean number of polyps and adenomas per patient was derived. Independent proportions and their differences were calculated using DerSimonian and Laird random-effects modeling. Results: Seven studies, including 2,595 CADe-assisted colonoscopies and 2,622 conventional colonoscopies, were analyzed. CADe-assisted colonoscopy demonstrated an 80% increase in the mean number of diminutive adenomas detected per patient compared with conventional colonoscopy (0.31 vs. 0.17; effect size, 0.13; 95% confidence interval [CI], 0.09-0.18); it also demonstrated a 91.7% increase in the mean number of nonpedunculated adenomas detected per patient (0.32 vs. 0.19; effect size, 0.05; 95% CI, 0.02-0.07). Conclusions: CADe-assisted endoscopy significantly improved the detection of most commonly missed adenomas. Although this method is a potentially exciting technology, limitations still apply to current data, prompting the need for further real-time studies.

Purpose - The aim of this paper is to examine the newly formed a partnership of Amazon, Berkshire Hathaway (Berkshire) and JPMorgan through the lens of strategic alliance, corporate philanthropy, and corporate social responsibility. Research design, data, and methodology - This is an analytical case study that examines the existing scholarly articles in strategic alliances, corporate philanthropy, and corporate social responsibility to explain the recent strategic alliance. Results - There is a clear limitation in explaining this type of unconventional strategic alliance with exiting definitions and concepts because there is no existing study or case available today. Forming a strategic business alliance to create and operate healthcare for their domestic employees could be viewed as a social innovation that resulted from an effort to resolve a social problem, the ineffective healthcare system in the U.S., rather than focusing on business benefits and profits. Conclusions - The success or failure of this type of business alliance would certainly affect the current healthcare system of the United States and global businesses and healthcare industries in the future. However, just entering or tapping into uncharted territory by these three companies to deal with a social issue is significant enough to merit further exploration and analysis for scholars and practitioners.
