        This study investigated the nutritional characteristics of before and after fermentation of domestic soybean (Glycine max L.) by Rhizopus oligosporus. The soybean storage proteins, β-conglycinin (11S globulin) and glycinin (7S globulin), were the most abundant in Seonyu (SY) and Danbaegkong (DBK), with concentrations of 253.4 mg/g and 193.0 mg/g, respectively. For 11S/7S related to sulfur-containing amino acid, DBK had a value of 0.95, making it the most excellent nutritionally among all the cultivars. The free amino acid content significantly increased from 0.04~10.45 mg/g before fermentation to 1.37~16.95 mg/g after fermentation, and the essential amino acid composition increased, confirming an improvement in protein quality after fermentation. Phytic acid, known as a nutritional inhibitor of soybeans, decreased from 1.66~2.13 g/100 g before fermentation to 0.90~1.58 g/100 g after fermentation, suggesting that mineral absorption inhibition was alleviated. In addition, the trypsin inhibitor content is suppressed by 76.20% to 81.25% after fermentation, which is expected to improve protein utilization in the body. This study confirmed some properties of fermented products by Rhizopus oligosporus using domestic soybeans, and these results are presented to serve as the basic data for establishing new uses of Korean soybean cultivars.

        Vulnerable populations in healthcare facilities are more sensitive to exposure to indoor air pollutants, and therefore are more affected by such pollutants than the general population. This was the underlying reason why studies of indoor air pollutant concentration distribution and health risk assessment have been conducted targeting facilities, such as daycare centers, medical facilities, elderly care facilities, and postnatal care centers. However, previous studies have mainly focused on daycare and medical facilities for their research, and relatively speaking, studies conducted on the other venues are lacking. Therefore, this study aims to present the current status of indoor air quality and perform a health risk assessment in regard to Formaldehyde exposure at postnatal care centers and elderly care facilities. Here, the study focused on facilities that had undergone pollution level inspections from January 2017 to December 2021. A total of 81 postnatal care centers and 48 elderly care facilities were selected as the subject of the study. Then, the study utilized concentrations of five elements (CO2, HCHO, PM10, PM2.5, TBC) to determine the status of indoor air quality of both postnatal care centers and elderly care facilities. For health risk assessment, HCHO concentration was used. The investigation demonstrated that the yearly average concentration of the five elements stood within the indoor air quality maintenance standards, and the ratio of PM2.5 to PM10 in the two types of facilities was distributed as high as about 70%. In addition, the study showed that HCHO and TBC demonstrated a positive correlation when the relationship between indoor temperature and humidity with the five elements was examined. The health risk assessment showed that the cancer risk level of postnatal care center users stood below 10-6, below the level that is perceived as an acceptable risk. The cancer risk of workers from both postnatal care centers and elderly care facilities and elderly care facility users exceeded the acceptable risk level of 10-6, but was shown to be below 10-4, the maximum acceptable risk.

        The restraints are used in the intensive care unit as a way to restrict the movement of the whole body or part of the body for the safety of the patient, such as maintaining medical equipment, preventing falls and patient self tube removal through regulating the patient's behavior. However, the physical restraints are used for the physical safety of the patient, but that is cause a variety of physical and psychological complications. Thus, nurses in intensive care units who apply restraint on face an ethical dilemma in the confrontation between the nurse's duty to improve the patient's health and protect the patient's safety and the value of the patient's autonomy and dignity. We have two examples are proposed to identify the ethical dilemma situation faced by nurses, to induce an active attitude towards elimination by establishing exactly restraint - removal criteria. In addition, it is proposed to seek a balance of individual values through active communication between the patient and the medical staff regarding the application of the restraint.

        With the enforcement of the “Act on decisions on life-sustaining treatment for patients at the end of life” in February 2018, discussion on advanced care planning (ACP) has increased. However, as decisions on life-sustaining treatments are still made in the intensive care unit, deaths related to the suspension of life-sustaining treatment account for a large proportion of deaths in the intensive care unit. The nurses encounter challenges in supporting the patient's dignified death; they experience an ethical dilemma in the ambiguity due to a lack of guidance on legal responsibilities regarding decisions on life-sustaining treatment. In order for the nurses to perform as a supporter providing care to the patients and as a advocate during the process of decision-making on life-sustaining treatment, there should be a systemic change to ensure the nurses' participation. In addition, an open and continuous discussion should be proposed to cultivate nurses’ ethical sensitivity and moral courage. This paper reports two ethical examples related to the decisions on life-sustaining treatment occurred in intensive care units of a tertiary hospital.

        This study was conducted to define the concept of social stigma related to COVID-19 and to identify attributes of nurses with experience in nursing COVID-19 confirmed patients. The study analysis method used the hybrid model of Schwartz-Barcott and Kim, and data was collected from literature related to social stigma and 7 nurses who had experience caring for confirmed COVID-19 patients. As a result of this study, the social stigma related to COVID-19 of nurses who have experience nursing confirmed patients was derived into three attributes. The three areas were derived from undervaluation, discrimination, and negative stereotypes. As a result, social rejection, social isolation, and lack of social support were found. As a primary result, cognitive response to inequality, emotional response to increased stress, increased anxiety, disappointment, alienation, and avoidance appeared. As a secondary result, negative self-concept, destruction of self-integration, self-stigmatization, and job satisfaction were shown. As a result, this study is meaningful in that it provided a practical foundation for a strategy to reduce social stigma related to COVID-19 of nurses who have cared for COVID-19 confirmed patients.

        Saengcheonggukjang, known as Natto in Japan, is a soybean fermented food which is made from steamed soybean, Bacillus and water. Demand of Saengcheonggukjang has increased because it does not have much smell compared to Cheonggukjang. Seven varieties of Saengcheonggukjang were investigated and compared in terms of 100 seed weight, quality characteristics, hard seed rate, and water absorption rate in order to determine the suitability of Korean soybeans. In addition, each characteristic of Saengcheonggukjang was compared. ‘Hoseo’ and ‘Haewon’ showed low 100 seed weight with 8.41 g and 8.11 g, respectively. The water absorption rate was higher in ‘Hoseo’ and ‘Pungwon’ than in Japan varieties. The yield of Saengcheonggukjang was significantly different for each variety. No differences were observed in yield and hardness of Saengcheonggukjang with respect to the varieties and sowing date. ‘Haewon’ showed the highest amino nitrogen content with 575.0 mg%. Viscous material content did not appear to differ between varieties. These results suggested that ‘Hoseo’ and ‘Haewon’ can be considered as suitable candidates for yield and quality of Saengcheonggukjang compared to Japan varieties.

        This experiment was performed to analyze the annual variation of growth traits of soybean to determine the information of less sensitive traits and stable cultivars based on the environmental conditions. Sowing was carried out on June 2 for each year and the test plot was arranged in three replicates by randomized complete block design with thirty soybean varieties including two landraces during the period 2014-2015. The weather conditions during the test period were quite different with extremely low precipitation and longer sunshine duration in 2015. The variation of characteristics related to growth period such as days of growth, days of maturity, days of flowering and 100-seed weight were less in spite of different environmental conditions. While the variation of the number of pods per plant was high. Considering growth and seed characteristics like the number of pods per plant, the number of seeds per pod, and 100-seed weight which are linked directly to the yield, cultivars such as Shingi, Daewonkong, Danbaegkong, and Daepung for beancurd and soypaste, Pungwon, Haepum and Shingang for soy-sprout and Seoritae for cooking with rice were more stable and are expected to have high yield in Suwon, the south-central part of South Korea. These results are useful for the selection of breeding resources to develop cultivars with high stability under changeable weather condition.

        With the increasing popularity of nonprofit thrift shopping, new marketing strategies are needed to respond to accelerated competition in the secondhand market. To help guide the development of marketing strategies for nonprofit thrift stores, this study aims to identify factors impacting consumers’ buying behavior for secondhand fashion items sold in nonprofit thrift stores. Specifically, this study investigated 1) the effects of secondhand fashion selection criteria (i.e., design, brand name, lower price) and personal factors (i.e., gender, household income, beliefs about environment) on the secondhand fashion consumption experience in nonprofit thrift stores and 2) the moderating effects of point of purchase (POP) messages (i.e., “50% Off Sale,” “New Arrivals,” “Helping Others”) on the relationships between purchase intention and impulsive buying in nonprofit thrift stores. An online survey was used to collect the data, and a total of 197 usable responses were received. The results showed that 1) gender, household income, beliefs about environment, and brand name affected the secondhand fashion consumption experience and 2) the POP message “Helping Others” negatively moderated the relationship between purchase intention and impulsive buying in nonprofit thrift stores. These results can help nonprofit thrift stores’ managers to develop effective marketing strategies to increase their profits, which can be used to accomplish their mission of addressing social issues.
