This study aimed to identify factors that influence the intention to use smart monitor-based mobile health (SBM) technology among middle-aged inpatients, based on the technology acceptance model II (TAM II).

A total of 222 participants were surveyed. Data were analyzed using SPSS Statistics 23.0 and IBM SPSS Amos 23. Seven exogenous variables–social influence (SI), personal self-efficacy, (PSE), environmental self-efficacy (ESE), health literacy, health concerns, resistance to innovative technology (RIT), accessibility (AC)– and three endogenous variables–perceived ease of use (PEOU), perceived usability (PU), and intention to use (ITU)–were investigated.

The hypothesized path model demonstrated a good fit for the data. SI (β = .13, p = .042), PU (β = .46, p < .001), and PEOU (β = .16, p = .008) had significant direct effects on the ITU, which explained 39.5% of the variance. Additionally, SI (β = .27, p < .001), ESE (β = .16, p = .010), RIT (β = - .12, p = .026), AC (β = .28, p < .001), and PEOU (β = .20, p = .001) indirectly affected ITU through PU, which explained 50.7% of the variance. Furthermore, PSE (β = .38, p < .001) indirectly influenced ITU via PEOU, which explained 38.4% of the variance.

This study demonstrates that the TAM II can be used to effectively predict ITU in SBMs among middle-aged inpatients. To expand the intention to use SBMs, it is necessary to develop SBMs that include content and programs that promote PU, SI, and PEOU.

Recent years have seen an increase in the number of pregnant women whose weight gain during pregnancy exceeds the recommended range. This study was intended to determine the relationships among demographic attributes, key perceptual factors, and gestational weight gain (GWG).

This cross-sectional study was conducted between April and July 2022. First-time pregnant women beyond 36 weeks of gestation who were recruited via social media completed an online survey. Data were analyzed using one-way ANOVA, chi-square test, and logistic regression, all performed using SPSS software.

Of the 369 participants, 63 (17.1%) exceeded the recommended GWG guidelines, while 148 (40.1%) fell within the recommended range, and the remaining 158 (42.8%) had inadequate GWG. Being overweight or obese before pregnancy significantly increased the risk of excessive GWG (p < .001). This risk was also significantly greater for women with low internal weight locus of control (OR = 0.58, 95% CI 0.41~0.82), high external weight locus of control (OR = 1.75, 95% CI 1.31~2.34), and negative body image (OR = 0.62, 95% CI 0.51~0.75).

The growing trend of excessive GWG among pregnant women is influenced by a combination of prepregnancy body mass index (BMI) and perceptual factors, including weight locus of control and body image. These findings underscore the need to implement weight management intervention strategies before pregnancy, taking into consideration BMI, and to enhance positive body image and internal locus of control.

This study was intended to provide basic data for reducing the career plateaus of clinical nurses.

The participants were 288 clinical nurses who worked at five hospitals, general hospitals, and tertiary hospitals in Seoul, Gyeonggi, and Chungcheong provinces and had more than one year of clinical experience. The research data were collected from December 26, 2022, to April 7, 2023, using structured questionnaires and analyzed using SPSS software. The study conducted mean, standard deviation, percentage, t-test, ANOVA, Pearson‘s correlation coefficient, and hierarchical regression analysis.

Perceived organizational support was identified as the factor influencing structural career plateaus. Factors influencing content career plateaus included growth needs, skill variety, organizational justice, and perceived organizational support.

The above research results suggest that to increase the motivation of clinical nurses and reduce career plateaus, it is necessary to improve awareness and systems of human resource management at the organizational level.

This study was performed to develop a self-efficacy theory-based exercise program for total knee arthroplasty (TKA) and to test the program’s efficacy in ameliorating knee pain and restoring function as measured by lower extremity muscle strength, 3 meter walking time, Korean Western Ontario McMaster Index (WOMAC), exercise self-efficacy, and length of hospital stay for TKA patients.

This quasi-experimental study incorporating a non-equivalent control group and pretest-posttest non-synchronized design non-synchronous design was applied to assess self-efficacy reinforcement strategies based on self-efficacy theory. The exercise program consisted of the following steps: TKA, education to prevent postoperative complications, and muscle strength exercises. Respective exercise and control groups included 29 and 27 participants. The experimental group received eight sessions of the program from three weeks before TKA to four weeks after TKA. Collected data were analyzed using the chi-square test, Mann–Whitney U test, and ranked ANCOVA and t-tests using IBM SPSS Statistics 23.

Experimental group showed significant improvement in lower extremity muscle strength (F = 8.63, p = .005), 3 meter walking time (z = - 5.02, p < .001), WOMAC index (z = - 2.22, p = .027), self-efficacy for exercise (z = - 3.29, p = .001), and length of hospital stay (t = - 2.11, p = .040) compared to the control group. No significant differences in knee pain and range of motion were observed.

These findings indicate that a self-efficacy theory-based exercise program can be an effective exercise strategy that patients undergoing TKA can easily follow at home without assistance. It is thus recommended as an exercise intervention for TKA patients.
