Physical activities are decreasing and sitting time is increasing due to the automation, smartization, and intelligence of necessary household items throughout daily life. Recent healthcare studies have reported that the likelihood of obesity, diabetes, cardiovascular disease, and early death increases in proportion to sitting time. In this paper, we develop a sitting posture correction cushion in real time using capacitive pressure sensor based on conductive textile. It develops a pressure sensor using conductive textile, a key component of the posture correction cushion, and develops a low power-based pressure measurement circuit. It provides a function to transmit sensor values measured in real time to smartphones using BLE short-range wireless communication on the posture correction cushion, and develops a mobile application to check the condition of the sitting posture through these sensor values. In the mobile app, you can visualize your sitting posture and check it in real time, and if you keep it in the wrong posture for a certain period of time, you can notify it through an alarm. In addition, it is possible to visualize the sitting time and posture accuracy in a graph. Through the correction cushion in this paper, we experiment with how effective it is to correct the user's posture by recognizing the user's sitting posture, and present differentiation and excellence compared to other product.

Objective : To summarize clinical and demographic variables and machine learning uses for predicting functional outcomes of patients with stroke. Methods : We searched PubMed, CINAHL and Web of Science to identify published articles from 2010 to 2021. The search terms were "machine learning OR data mining AND stroke AND function OR prediction OR/AND rehabilitation". Articles exclusively using brain imaging techniques, deep learning method and articles without available full text were excluded in this study. Results : Nine articles were selected for this study. Support vector machines (19.05%) and random forests (19.05%) were two most frequently used machine learning models. Five articles (55.56%) demonstrated that the impact of patient initial and/or discharge assessment scores such as modified ranking scale (mRS) or functional independence measure (FIM) on stroke patients' functional outcomes was higher than their clinical characteristics. Conclusions : This study showed that patient initial and/or discharge assessment scores such as mRS or FIM could influence their functional outcomes more than their clinical characteristics. Evaluating and reviewing initial and or discharge functional outcomes of patients with stroke might be required to develop the optimal therapeutic interventions to enhance functional outcomes of patients with stroke.

In this study, we investigated and the following conclusions are presented by identifying the current status and problems in order to expand the future's value of the community care project introduced and implemented to improve the quality and care for the elderly's life. First, the needs analysis of the elderly receiving services is composed of patient-centered rather than investigator-centered, and in particular, medical management through medical staff visits should be strengthened, and specialized service items according to gender, age, disability type, and personal preference should be strengthened. This will have to be gradually strengthened. Second, by analyzing the satisfaction, redundancy, and effectiveness of service items, we save money, and consider the consumer-oriented service item composition and application of items necessary for new services. Third, through the introduction of an integrated schedule management system, it is necessary to specialize in pre-booking and visit schedule management between the elderly and the direct service organizations that provide services. Fourth, as an effort to solve the financial problem, it is necessary to prepare a rational resource sharing system with health and medical finance, long-term care insurance system, and social welfare financial project. and it may consider that putting the medical personnel who are from local public medical college input. Through these proposals, the community care business will be able to complete and have future value as a universal aged care system.

To minimize the effects of aging-related comorbidities and to maintain a good quality of life and physical independence for a longer period, the improvement of lifestyle and dietary habits is essential, and healthy foods can be helpful. Among them, medicinal plant such as ginseng (Panax ginseng) and bellflower (Platycodon grandiflorum) contain natural functional substances and have been used for disease treatment and prevention since ancient times. This review summarizes the scientific of these treatments basis by investigating the pharmacological and pharmacokinetic effects of major functional substances on the aging-related health effects of Panax ginseng and Platycodon grandiflorum. The main functional substances of Panax ginseng and Platycodon grandiflorum are saponins, which have a similar molecular structure and confirmed anti-inflammatory, antioxidant, neuroprotective, anticancer, and anti-metabolic syndrome effects (improvement of hypertension, dyslipidemia, diabetes, and obesity). Both types of saponins in Panax ginseng (Ginseonside) and Platycodon grandiflorum (Platycoside) have very low absorption profiles in their purified state, but methods to increase absorption in the body through extraction or fermentation have been studied.

For this study, we designed and produced mulberry low-fat ice cream supplemented with synbiotics (MLF-ISS). The sensory characteristics and physical, chemical, and microbiological qualities of MLF-ISS were then determined. Mulberry juice inoculated with or without probiotic (Lactobacillus plantarum TISTR 926 and Saccharomyces boulardii CNCM I-745) was also tested at 37℃ for 24 h to determine probiotic growth rate, pH, total anthocyanin content (TAC), total phenolic content (TPC), and antioxidant activity (AA). Only the TAC of mulberry juice inoculated with S. boulardii CNCM I-745 increased considerably (p < 0.05) among these parameters. MLF-ISS was produced with varied mulberry fruit concentrations (0, 10, 20, 30, or 40%) (w/w). The MLF-ISS prepared with 30% mulberry fruit (w/w) (30-MLF-ISS) had a higher score in appearance, color, and sweetness (p < 0.05) when sensory qualities were measured using the 9-point hedonic scale method. In the CIE lab system (L^*, a^*, b^*), the color values of 30-MLF-ISS were 27.80 ± 0.26, 12.99 ± 0.59, and 1.43 ± 0.05, respectively. The 30-MLF-ISS was also subjected to a proximate analysis. The melting rate of 30-MLF-ISS was 0.29 ± 0.03 g/min and the time it took for the first drop to fall was 37.00 ± 7.00 min. TAC, TPC, and AA of 30-MLF-ISS were observed to alter significantly (p < 0.05) during varied intervals of storage at - 18℃ (0, 30, and 60 days). The viability of probiotics in 30-MLF-ISS slightly decreased after storage at -18℃ for 8 weeks, but remained about 6 log CFU/g. During storage at -18℃ for 0 and 120 days, no pathogenic bacteria were detected in 30-MLF-ISS. These findings show that 30-MLF-ISS has nutritional and functional value, is free of foodborne pathogenic bacteria, is safe for consumers' health, and is suitable for application in the ice cream and related food industries.

This study tested whether the evaluation of moral cleansing behavior following an immoral act depends on the resources available to the wrongdoer. To this end, resource availability was manipulated by the wrongdoer's characteristics (socioeconomic status vs. physical health condition) and type of moral cleansing (donation vs. volunteer work), and participants rated the pain of the moral cleansing behavior, hypocrisy, and forgivability. Study 1 presents a scenario where a wrongdoer, either high or low in socioeconomic status, conducts moral cleansing via donation or volunteer work. Participants judged donation by those high in socioeconomic status to be not so painful, hypocritical, and unforgivable. Study 2 described a scenario in which a wrongdoer, either physically strong or weak, performs an act of moral cleansing either by donation or volunteer work. Participants considered those sickly wrongdoers' volunteer work to be painful, less hypocritical, and (compared with other conditions) more forgivable. Mediation analyses showed that in both Studies 1 and 2, pain in moral cleansing influenced the hypocrisy judgment which, in turn, affected perceived forgivability. These results indicate that, even for the same expiatory behavior, moral judgment depends on the actor's available resources. That is, people believe that moral cleansing should involve pain; otherwise, the act is hypocritical and unforgivable.

Human urine is a process of excreting waste products in the blood, and it is easy to collect and contains various substances. Urinalysis is used to check for diseases, health conditions, and urinary tract infections. There are three methods of urinalysis: physical property test, chemical test, and microscopic test, and chemical test results can be easily confirmed using urine test strips. A variety of items can be tested on the urine test strip, through which various diseases can be identified. Recently, with the spread of smart phones, research on reading urine test strips using smart phones is being conducted. There is a method of detecting and reading the color change of a urine test strip using a smartphone. This method uses the RGB values and the color difference formula to discriminate. However, there is a problem in that accuracy is lowered due to various environmental factors. This paper applies a deep learning model to solve this problem. In particular, color discrimination of a urine test strip is improved in a smartphone using a lightweight CNN (Convolutional Neural Networks) model. CNN is a useful model for image recognition and pattern finding, and a lightweight version is also available. Through this, it is possible to operate a deep learning model on a smartphone and extract accurate urine test results. Urine test strips were taken in various environments to prepare deep learning model training images, and a urine test service application was designed using MobileNet V3.

Radical changes in modern society have influenced on the nature of the works and the importance of the career education is emphasized more than any time. Various scholars have continuously emphasized the importance of the career education in regular schools. Most career educations in regular schools, however, consist of one-time event-oriented programs because of the systematic limitations immanent in Korean school system. To overcome the limitations of the school system, scholars have contended that career educations in regular schools should be integrated into the existing subjects and the curricula. Therefore, it is necessary to analyze exemplary cases of the career education through the subjects integration in developed countries. The target of the analysis in this study was the career education related content in Australia because Australian federal and local governments have made great efforts in integrating the career education into the regular school curricula. With interviews and literature analysis, the current status of the career education through the subjects integration in federal and local governmental levels and the career education related contents in the regular school curricula of local governmental level were analyzed. Major findings of the study were as follows: 1) Career education components were mainly contained in the PDHPE(personal development, health and physical education) subject in New South Wales; 2) Understandings of a wide range of work were emphasized in the cross-curricular perspective in South Australia; 3) Career education components were mainly contained in the SOSE(studies of society and environment) subject in Victoria; and 4) Career education related contents were integrated mainly in the 'inner learner' unit in Essential Learning subject in Northern Territory. The conclusions were derived from the outcomes of the study and the recommendations were proposed for the applications of the study results and the future researches.

The purpose of this study was to investigate attitudes toward aging and depression among elderly welfare facility users. For this purpose, a questionnaire-based survey was conducted with 280 elderly participants in the facilities of 15 institutions in Gyeonggi-do. In total, 258 data points were used for analysis. The measuring instruments used an attitude scale and depression scale for aging. The results of this study are as follows. First, there was no difference in attitude toward aging and depression among elderly welfare institution users by gender. Second, attitudes toward aging among elderly welfare facility users were also assessed according to final educational background. Positive attitudes in general (lack of depression) and positive attitudes toward aging were found to be higher with a higher rate of final academic completion. Third, attitudes toward aging were assessed according to experience with welfare facilities among the elderly, and it was found that depression has a significant impact on perceptions of physical change caused by aging. As a result, even when attitudes toward aging are generally negative, an elderly person cannot be judged to be depressed because this is highly related to final academic completion. Therapists working in welfare facilities for the elderly are more likely to have negative attitudes toward aging and depression when the number of facilities used is lower.
