Purpose: This study aimed to provide a systematic review and meta-analysis of research on flipped learning effects applied to university students. Methods: The random effect model was applied to 21 papers to calculate the effect size. To verify the moderation effect, a meta regression analysis and meta ANOVA were performed. Publication bias was verified through a funnel plot, and then an Egger's regression test was conducted. Results: The overall average effect size was .69 (95% CI: .51-.87), showing a median effect size, which was statistically significant. The outcome variables were in the order of learning motivation (Hedges’ g=.83), self-directed learning (Hedges’ g=.78), learning achievement (Hedges’ g=.66), and efficacy (Hedges’ g=.50), which were statistically significant. Conclusion Flipped learning was found to be statistically significant in improving self-directed learning, learning motivation, efficacy, and learning achievement amng university students. It is suggestd that this method be actively applied in university education.

Elastofibroma is a rare benign tumor-like condition manifesting as firm and spherical mass with poorly circumscribed margins of fibroelastic tissue, occuring in the subscapular region or the chest wall of elderly persons. It is not a true neoplasm but rather a reactive or degenerative process causing abnormal elastogenesis. It is unilateral in the majority of cases and the right side is affected more commonly than the left. We report a case of bilateral elastofibromas removed from both subscapular regions of a 73-year-old female farmer. She was presented with tender masses on the bilateral subscapular areas for seven years. Microscopically, it consisted of a mixture of intertwining broad eosinophilic collagen bundles and elastic fibers associated with a few fibroblasts and mature fat cells. The elastic fibers had a degenerated beaded appearance or were fragmented into serrated globules in a linear arrangement.

Primary malignant lymphoma of the appendix is an unconnnon neoplasm although the gastrointestinal tract is the most common extranodal site of malignant lymphoma. We report a case of primary malignant lymphoma of the appendix in a 54-year-old male, who presented with pain in the right lower abdomen. An appendectomy was performed. The appendix measured 9.5 cm in length and 5.5 cm in diameter. Cut sections showed a solitary circumferential mass in the appendiceal lumen. Light microscopic features were compatible with malignant lymphoma of diffuse large cell type(Working Formulation) and the immunophenotype was B cell type.

Lichen planopilaris is believed to be a variant of lichen planus which is occasionally accompanied by classical lichen planus. A 68-year old male had asymptomatic skin colored or light violet colored papules and nodules on the occipital area followed by hair loss for 2 months. He had also violaceous pea to bean sized whitish scaly papules on the right lower extremity. Histopathological examination revealed the dilated follicles to be filled with horny material. There were also intense infiltrations of monocytes which were most prominent at the lower pole of the hair follicles on the scalp lesion. There was also hyperkeratosis, focal hypergranulosis and band-like infiltrations of lymphocytes at the dermo-epidermal junction on the lesion of the lower extremity. Direct immunofluorescence examination showed linear deposition of fibrin at the dermo-epidermal junction in the hair follicles. We had an opportunity to observe a man with lichen planopilaris who had loss of scalp hair which was accompanied by classical lichen planus on the lower extremity.

Purpose: This study was done to determine the correlations among grit, social support, career barriers, and career preparation behavior in mature age nursing students, and identify factors influencing their career preparation behavior. Methods: This cross-sectional, descriptive study included 106 undergraduate nursing students aged 25 years or older at the time of entering three universities in Korea. Grit, social support, career barriers, and career preparation behavior were investigated using structured questionnaires. Data analyses included descriptive statistics, independent t-test, one-way ANOVA, Pearson’s correlation analysis, and stepwise multiple regression analysis and were performed with the SAS program (version 9.4). Results: The factors influencing career preparation behavior of mature age nursing students included: persistence of efforts (β=.35, p<.001) and consistency of interests (β=-.21, p=.011) under the sub-domains of grit; informational support (β=.29, p<.001) under the sub-domains of social support; lack of job information (β=-.36, p<.001) and anxiety about the future(β=.28, p=.008) under the sub-domains of career barriers. These variables accounted for approximately 42% of the variance in career preparation behavior. Conclusion The findings imply that in order to improve the career preparation behavior and lower the career barriers of mature age nursing students, their individual cognitive and psychological characteristics should be considered while providing diverse job information as part of career guidance.

Purpose: The purpose of this study was to investigate the effects of home-and-workplace combined exercise on physical function, depression, and work-related disability in patients with ankylosing spondylitis. Methods: This study adopted a non-randomized quasi-experimental design. Fifty-two patients were recruited: home-and-workplace combined exercise (n = 17), home exercise (n = 18), and control group (n = 17). Results: The home-and-workplace combined exercise group showed improvement in spinal mobility and pulmonary function and significantly lower absenteeism and overwork impact than the home-exercise group and control group. The home-and-workplace combined exercise and home exercise groups showed a higher level of activity improvement than the control group. Conclusion home-and-workplace combined exercise can be recommended to patients with ankylosing spondylitis to enhance their physical function, including spinal mobility and pulmonary function, and reduce work-related disability.
