This study is to analyze the effects of dietary life education of elementary school students by gender and by grade to seek for solutions of activating the rural convergence industry in linkage with dietary life education. Subjects were 152 students of eight elementary schools in Chungcheongnam-do. As a result of the study, after application of the dietary life education program, the scores were statistically significantly improved and four sub areas(education at the dining table, practice of green dietary life, reduceing food wastes, learning about local foods) showed a statistically significant improvement. Scores by gender were statistically significantly improved among both male and female students and the results of analyses by gender in four sub areas of dietary life education were also statistically significantly improved. Scores by grade were statistically significantly improved in all grades and the results of analyses by grade in four sub areas of dietary life education were also statistically significantly improved. Since the dietary life education program in the present study is effective for dietary life improvement, the results of the present study are expected to be utilizable in education of elementary school students and lead to the consumption of regional foods by increasing the ability to select proper foods.

Incorporating renewable fuel into practice, especially from algae, is a promising approach in reducing fossil fuel dependency. Algae are an exceptional feedstock since they produce abundant biomass and oils in short timeframes. Algae also produce high-valued lipid products suitable for human nutrition and supplement. Achieving goals of producing algae fuels and high-valued lipids at competitive prices involves further improvement of technology, especially better control over cultivation. Manipulating microalgae cultivation conditions to prevent contamination is essential in addition to promoting optimal growth and lipid yields. Contamination of algal cultures is a major impediment to algae cultivation that can however be mitigated by choosing extremophile microalgae. This work describes the isolation of alkali-tolerant / alkaliphilic microalgae native to South Florida with ideal characteristics for cultivation. For that purpose, water samples from Lake Okeechobee were inoculated into Zarrouk's medium (pH 9-12) and incubated for 35 days. Selection resulted in isolation of three strains that were screened for biomass and lipid accumulation. Two alkali-tolerant algae Chloroidium sp. 154-1 and Chlorella sp. 154-2 were poor lipid accumulators. One of the isolates, the diatom Fistulifera sp. 154-3, was identified as a lipid accumulating, alkaliphilic organism capable of producing 0.233 g L^-1 d^-1 dry biomass and a lipid content of 20-30% dry weight. Lipid analysis indicated the most abundant fatty acid within Fistulifera sp. was palmitoleic acid (52%), or omega-7, followed by palmitic acid (17%), and then eicosapentanoic acid (15%). 18S rRNA phylogenetic analysis formed a well-supported clade with Fistulifera species.

Purpose: This study examined socio-demographic and health status factors associated with hazardous drinking in male and female elderly with hypertension. Methods: The sample consisted of 2,322 seniors with hypertension and was obtained from the Seventh Korean National Health and Nutrition Examination Survey (VII-1, VII-2, VII-3). Complex sample analysis was performed using the independent t-test, the Chi-square test and multiple logistic regression in SPSS/WIN 24.0 program. Results: The factors associated with hazardous drinking in the male hypertensive seniors were age (OR=2.13, CI=1.37-3.32), weekly drink number (OR=0.11, CI=0.07-0.16) and weight gain control (OR=0.44, CI=0.21-0.94), and corresponding factors in female hypertensive seniors were age (OR=4.56, CI=2.37-8.80), income level (OR=1.88, CI=1.05-3.37), weekly drink number (OR=0.09, CI=0.04-0.17), current smoking (OR=6.88, CI=2.29-20.64), weight loss control (OR=1.99, CI=1.14-3.47), hypertension treatment (OR=35.62, CI=2.02-629.43), and hypertension drug (OR=0.06, CI=0.01-0.61). Conclusion: Risk drinking in elderly with hypertension was found to be related to personal characteristics and health status. Therefore, to manage hypertension effectively in the elderly, drinking patterns should be improved and active participation in the practice of healthy activities such as weight control, smoking cessation, and decreased alcohol intake, should be encouraged.

Purpose: This study was to identify health behavior, health service use, and health related quality of life of adult women in one-person and multi-person households. Methods: It was used data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-2017). Subjects were 2,522 women with age of 19 to 64 years in 2017. Complex sampling design and data analysis were performed using SPSS 20.1. Results: Women in one-person households had higher rates of alcohol drinking (${\chi}^2=13.77$, p=.003), smoking (${\chi}^2=16.07$, p=.001), unmet medical care (${\chi}^2=8.77$, p=.004) and non-practice of cancer screening (${\chi}^2=13.77$, p=.003) compared to women in multi-person households. Health-related quality of life was also lower for women in one-person households (t=-2.46, p=.015). Factors affecting health-related quality of life in one-person households were household income, job status, and unmet dental care, having 32.4% explanatory power. One-person household women with low incomes, no jobs, and unmet dental care showed low health-related quality of life. In comparison, factors affecting health-related quality of life of women in multi-person household women were age, education level, unmet medical care, and unmet dental care, having 10.4% explaining power. Women in multi-person households with age of 60-64, low education level, unmet medical care, and unmet dental care showed low health-related quality of life. Conclusion: Health promotion strategies should be developed based on unique understanding of social, economic, and health of adult women in one-person and multi-person households.

Purpose : The routine evaluation of gastric residuals (RGR) is considered standard care for premature infants. This study evaluated the usefulness of RGR in premature infants. Methods : The study retrospectively investigated 208 premature infants (gestational aged under 34 weeks) who underwent gavage feeding in a neonatal intensive care unit at a tertiary hospital. The patients were divided into two groups: RGR (n=104) and no-RGR (n=104). Those in the no-RGR group had their gastric residuals checked only if signs of feeding intolerance were present. Clinical outcomes, including the time to reach full enteral feeding (FEF) and the incidences of gastrointestinal disorders such as feeding intolerance (FI) and necrotizing enterocolitis (NEC), were compared. Data were analyzed with SPSS ver. 21, using a Mann-Whitney U test, chi-squared test, and Fisher's exact test. Results : There was no statistically significant difference for the time to FEF (z=-0.61, p=.541), incidence of FI ($X^2=0.38$, p=.540), and NEC ($X^2=1.42$, p=.234) between the two groups. Conclusion : No-RGR did not increase the risk for FI or NEC. These results suggest that RGR evaluation may not improve nutritional outcomes in premature infants. Recommendations for further research and practice guidelines will be provided.

Background: In physical activity or labor, the human body is in a state of high intensity stress, and all parts or physiological functions of the body respond positively to maintain or balance the need for movement. The human body has many physiological changes in the process of movement, and fatigue is the external manifestation of various complex changes inside the human body. Fatigue is also a physiological mechanism of self-protection after the body reaches a certain level of activity, which can prevent the occurrence of life-threatening excessive functional failure. The generation of fatigue is a very complex process, and its mechanism has not been concluded yet. Therefore, it is an important work to search and screen the effective components of natural plants that have anti-fatigue effect and to explore their mechanism. Methods: This was a 8-week, randomized, double-blind, placebo-controlled clinical trial. A total of 110 subjects who passed physical examination were included according to the scheme design, and randomly divided into a test group which was given KRG and a placebo control group. The calculation is carried out according to the standard of sub-high-intensity exercise test. Results: There was no adverse effect on safety index of subjects after taking red ginseng capsule. After KRG treatment, subjective strength grade is significant lower than placebo treatment. Blood lactic acid content is significantly get lower after trial in KRG group, and significant lower than placebo group. Creatine phosphokinase(CK) content is significantly get lower after trial in KRG group, and significant lower than placebo group. Conclusion: According to the criterion in the test scheme, the result shows that KRG is helpful on relieving physical fatigue.

Purpose: Extravasation of diagnostic and therapeutic materials might occur when the intravascular solution leaks into the surrounding tissues. Injury associated with extravasation depends on various factors. It may range from mild skin reaction to severe necrosis. However, the incidence rate for extravasation is largely unknown because of the limited reporting in Korea. Therefore, this study was conducted to identify the incidence of extravasation and nurses' attitude and knowledge of extravasation for providing high-quality nursing care. Methods: Three acute care hospitals were surveyed to estimate the occurrence of extravasation. Knowledge and attitude toward extravasation were investigated from 793 nurses working in six hospitals. Results: The incidence rate of extravasation was 0.5%. Extravasation commonly occurred in elderly patients aged 66 or older (59.9%) and internal medicine (48.2%), and it happened 13.73±20.68 days after hospitalization on average. It mostly occurred in the forearm site (52.9%) and was mainly caused by parenteral nutrition (33.6%). The mean scores of nurses' knowledge and attitude were 14.63±2.86 and 28.91±36.00, respectively. There was a significant negative correlation between the subjects' knowledge and attitude (r=-.11, p=.002). Conclusion: It is necessary to have a reporting system that can accurately monitor the occurrence of extravasation for patient safety management. In addition, it is necessary to develop a protocol that can be applied to clinical practice and a nurse education program.

Purpose: The purpose of this study was to analyze end-of-life care practices in lung disease patients with physician orders for life-sustaining treatment (POLSTs). Methods: We retrospectively analyzed data from medical records regarding the end-of-life care practices of POLST decisions for patients with lung disease hospitalized at a tertiary hospital in Seoul, South Korea. Data were collected from January 1 to June 30, 2021. Results: Of 300 total patients, 198 had lung cancer (66.0%) and 102 had non-malignant lung diseases (34.0%). A POLST was written for 187 patients (62.3%), and an advance directive was written for 20 patients (6.7%). Subsequent treatments were hemodialysis in 13 patients (4.3%), surgery in 3 patients (1.0%), and cardiopulmonary cerebral resuscitation in 1 patient (0.3%). Among cancer patients, chemotherapy was performed in 11 patients (3.7%), targeted therapy in 11 patients (3.7%), immunotherapy in 6 patients (2.0%), and radiation therapy in 13 patients (4.3%). Depending on the type of lung disease, types of treatment differed, including hemodialysis, ventilators, bilevel positive airway pressure, high-flow nasal cannulas, nebulizers, enteral nutrition, central line, inotropic agents, and opioids. Conclusion: Although the goals of hospice care are the same whether a patient has lung cancer or a non-malignant lung disease, because the characteristics of the respective diseases differ, end-of-life care practices and hospice approaches must be considered differently.

Since the enactment of the School Meal Support Act in 2009, South Korean dietary education has been evolving, placing health, environment, and consideration as its core values. The 3rd Basic Plan for Dietary Education (2020-2024) aims to achieve a sustainable dietary lifestyle that civic agriculture for collective consumption, healthy citizens, and an inclusive society. However, the digital civilization of the Fourth Industrial Revolution is significantly impacting dietary education in schools. Therefore, this study examines sustainable dietary education content in South Korean school meals, diagnoses the phenomena of dietary education facing digital transformation in education due to the Fourth Industrial Revolution, and explores directions for inclusive dietary education through concrete structures and content systems for inclusive dietary education that foster sustainable dietary capabilities. To achieve inclusive dietary education, a structure and system that allow cognitive, normative, and practical learning to be combined in an inclusive way is required. Furthermore, to practice sustainable dietary education, alternative approaches that emphasize the development of learners' core competencies are necessary in the direction of inclusive dietary education that fosters inclusivity.
