This study presents the development and validation of a risk assessment program of highly pathogenic avian influenza (HPAI). This program was developed by the Korean government (Animal and Plant Quarantine Agency) and a private corporation (Korea Telecom, KT), using a national database (Korean animal health integrated system, KAHIS). Our risk assessment program was developed using the multilayer perceptron method using R Language. HPAI outbreaks on 544 poultry farms (307 with H5N6, and 237 with H5N8) that had available visit records of livestock-related vehicles amongst the 812 HPAI outbreaks that were confirmed between January 2014 and June 2017 were involved in this study. After 140,000 iterations without drop-out, a model with 3 hidden layers and 10 nodes per layer, were selected. The activation function of the model was hyperbolic tangent. Precision and recall of the test gave F1 measures of 0.41, 0.68 and 0.51, respectively, at validation. The predicted risk values were higher for the “outbreak” (average ± SD, 0.20 ± 0.31) than “non-outbreak” (0.18 ± 0.30) farms ( The risk assessment model developed was employed during the epidemics of 2016/2017 (pilot version) and 2017/2018 (complementary version). This risk assessment model enhanced risk management activities by enabling preemptive control measures to prevent the spread of diseases.

Purpose:
The study aimed to design and develop an automated personalized self-care (APSC) program for patients with type 2 diabetes mellitus. The secondary aim was to present a clinical protocol as a mixed-method research to test the program effects.
Methods:
The APSC program was developed in the order of analysis, design, implementation, and evaluation according to the software development life cycle, and was guided by the self-regulatory theory. The content validity, heuristics, and usability of the program were verified by experts and patients with type 2 diabetes mellitus.
Results:
The APSC program was developed based on goal setting, education, monitoring, and feedback components corresponding to the phases of forethought, performance/volitional control, and self-reflection of self-regulatory theory. Using the mobile application, the participants are able to learn from educational materials, monitor their health behaviors, receive weekly-automated personalized goals and feedback messages, and use an automated conversation system to solve the problems related to self-care. The ongoing two-year study utilizes a mixed method design, with 180 patients having type 2 diabetes mellitus randomized to receive either the intervention or usual care. The participants will be reviewed for self-care self-efficacy, health behaviors, and health outcomes at 6, 12, 18, and 24 months. Participants in the intervention group will be interviewed about their experiences.
Conclusion
The APSC program can serve as an effective tool for facilitating diabetes health behaviors by improving patients’ self-care self-efficacy and self-regulation for self-care. However, the clinical effectiveness of this program requires further investigation.

Asian Nursing Research 2023;17(5):259-268
Purpose:
Preventing diabetic complications involves regular outpatient follow-up and maintaining low variability in hemoglobin A1c (HbA1c) levels. This study investigated the factors associated with diabetic complications, with a specific focus on the impact of regular outpatient follow-up and HbA1c variability, among patients with type 2 diabetes.
Methods:
The study design was secondary data analysis of electronic medical records from a university hospital in Korea. It included patients aged 40–79 with type 2 diabetes who were prescribed diabetes medication within three months of their first HbA1c test by an endocrinologist and were followed up for at least five years. Follow-up regularity, adjusted standard deviation of HbA1c levels, and diabetic complication indices were collected. Data were analyzed using the Chi-square test, independent t-test, repeated measures analysis of variance, and multiple regression analysis.
Results:
The study included 1566 patients. Lower follow-up regularity was observed in patients of older age, with comorbidities, diabetic complications, insulin treatment, a history of hospitalization, lower baseline estimated glomerular filtration rate (eGFR) and total cholesterol (TC), and higher HbA1c variability. Higher HbA1c variability was observed in younger patients without comorbidity but with insulin treatment, a history of hospitalization, higher baseline blood glucose (BG), HbA1c, TC, and triglyceride levels. HbA1c variability had the strongest influence on BG and HbA1c levels at the five-year follow-up. Baseline eGFR and TC were the most influential factors for their respective levels at the five-year follow-up. Follow-up regularity significantly affected BG, HbA1c, eGFR, and TC at five-year follow-up.
Conclusions
It has been shown that several variables besides regular follow-up and HbA1c variability have an influence. However, these are the two that can be corrected through nursing intervention and are important, so intervention on these is important.

γδ T cells are a rare and unique prototype of T cells that share properties with natural killer cells in secondary lymphoid organs. Although many studies have revealed the function and importance of adult-derived γδ T cells in cancer biology and regenerative medicine, the low numbers of these cells hamper their application as therapeutic cell sources in the clinic. To solve this problem, pluripotent stem cell-derived γδ T cells are considered alternative cell sources; however, few studies have reported the generation of human pluripotent stem cell-derived γδ T cells. In the present study, we investigated whether lymphoid lineage γδ T cells were successfully generated from human pluripotent stem cells via hemogenic endothelium under defined culture conditions. Our results revealed that pluripotent stem cells successfully generated γδ T cells with an overall increase in transcriptional activity of lymphoid lineage genes and cytolytic factors, indicating the importance of the optimization of culture conditions in generating lymphoid lineage γδ T cells. We uncovered an initial step in differentiating γδ T cells that could be applied to basic and translational investigations in the field of cancer biology. Based on our result, we will develop an appropriate method to purify γδ T cells with functionality and it helpful for the study of basic mechanism of γδ T cells in pathophysiologic condition as well as clinic application.

Purpose:
This study aimed to determine the consistency of 1-day and 3-day average dietary intake using the 24-hour diet recall method and to investigate the relationship of diet intake with physiological indicators potentially associated with diabetic complications in patients with diabetes.
Methods:
This study conducted a secondary data analysis using pretest data of a nursing intervention study entitled “Development of deep learning based AI coaching program for diabetic patients with high risk and examination of its effects (PNUH, IRB No. 05-2021-030).” Data were analyzed through descriptive analysis, one-way repeated-measures analysis of variance, and Pearson correlation coefficients using SPSS 26.0.
Results:
The average total daily calorie intake over 3 days was 1,494.48±436.47 kcal/day: 1,510.90±547.76 kcal/day on the first day, 1,414.22±527.58 kcal/day on the second day, 1,558.34±645.83 kcal/day on the third day, showing significant differences (F=3.59, p=.031). The correlation coefficient between the 1-day and 3-day average dietary intake was 0.41–0.77 for each nutrient and 0.62–0.80 for each food group. Vegetable intake showed negative correlations with body mass index (BMI; r=-.19, p=.023) and triglycerides (r=-.18, p=.036), whereas dairy intake was positively associated with low-density lipoprotein-cholesterol (LDL; r=-0.18, p=.034) and triglycerides (r=.40, p<.001).
Conclusion
This study demonstrated that 1-day dietary intake was highly correlated with 3-day average dietary intake using the 24-hour diet recall method. Food groups showed significant associations with physiological indicators of potential diabetic complications such as BMI, triglycerides, and LDL levels. Further studies are needed to improve the knowledge base on the relationships between physiological indicators and food groups.

The enhanced primary care demonstration (EPD) was launched in November 2014 to provide high-quality care for people with chronic illnesses. In the EPD, comprehensive assessment and care planning (CAP) is a critical component, along with behavior modification and case management services. In this study, we measured CAP duration and calculated the fee for CAP sessions performed with patients with hypertension and/or diabetes mellitus. In 5 primary care clinics participating in the EPD, the duration of CAP sessions and usual consultations was measured. The duration of CAP sessions was measured on 2 separate occasions because CAP involves 2 separate consultations, including an initial consultation for comprehensive patient assessment and laboratory testing and a follow-up consultation for creating a care plan based on the assessment and test results. The CAP fee was calculated as the ratio of CAP time to the usual consultation time. The median (interquartile range) and the mean ± standard deviation of CAP duration were 15.4 (7.1) minutes and 15.6 ± 4.2 minutes, respectively. The first and second CAP sessions lasted for 5.3 and 4.6 times longer than usual consultations, respectively. The calculated CAP fees were 76,299 won (median) and 65,766 won (mean). The length of CAP sessions for patients with hypertension and/or diabetes mellitus was approximately 5 times longer than that of usual consultations. If consultation lengths were measured in a representative patient sample, it would be possible to improve the external validity of the measurements.

Purpose:
The purpose of this study was to investigate the nutritional intake status, according to the risk of diabetic complications in Type 2 diabetes patients.
Methods:
This was a secondary data analysis study that included 83 patients. The nutritional intake was assessed, using 24-hour dietary recall. The risk of diabetic complications was measured, using the Framingham Risk Score (FRS) and Michigan Neuropathy Screening Instrument Questionnaire (MNSIQ). The nutritional intake was analyzed using the CAN-pro 4.0 program. Data were analyzed using descriptive statistics, Chi-square test, and Independent t-test, using the SPSS WIN 26.0 program.
Results:
The mean FRS and MNSIQ scores for the participants was 14.46 ± 4.09 and 2.30 ± 2.22, respectively. Thirty two participants (38.6%) were in the high-risk groups for cardiovascular disease and peripheral neuropathy. The participants consumed high amounts of grain and low amounts of vegetables, fruits, and dairy products when compared to the recommended intake. However, the nutritional intake did not differ according to FRS or MNSIQ levels. Consumption of vegetables and fruits were significantly different between high and low risk groups of MNSIQ.
Conclusion
It is necessary to consider the composition of dietary intake to improve the imbalanced diet in Type 2 diabetes patients and prevent diabetic complications. Type 2 diabetes patients should reduce the intake of grains and sodium, and increase vegetable intake. More deliberate future studies are needed, to investigate the relationship between food intake and the risk status for diabetic complication.

PURPOSE: This study was designed to investigate quality of life (QOL) differences between younger (<50 years) and older (> or =50 years) breast cancer survivors and to determine the unique effect of age on QOL after adjusting age-correlated variables. METHODS: One thousand two hundred fifty patients were enrolled. Clinicopatholgical and social parameters were reviewed and Functional Assessment of Cancer Therapy-Breast cancer instrument (FACT-B) and the Ladder of Life scale were used to measure the QOL. Among 1,250 eligible patients, 1,094 patients completed the questionnaire and were used for analysis. Chi-square test, t-test and a series of multiple regression analyses were conducted to verify age-related differences in QOL between two groups and to evaluate the unique contribution of age variable on QOL of breast cancer patients. RESULTS: Significant socio-demographic and clinical differences existed based on age categories, including education, job, time since surgery, chemotherapy and daily activity. Also, there were significant age-related differences in FACT-B total, physical well-being, social/family well-being, functional well-being and breast cancer subscale and in subjective QOL. Older patients > or =50 years showed significantly lower QOL than younger patients <50 years. However, after controlling for age-correlated variables including job, education, time since surgery, chemotherapy, and daily activity, there was no unique age difference in QOL among breast cancer survivors. CONCLUSION: Our study results suggest that older women with breast carcinoma suffered significantly lower QOL, even though the unique age effect was not found. Therefore, various interventions for enhancing QOL for women with breast carcinoma should be provided to older age group.
