The present study was conducted to investigate the efficacy of sweet potato powder (SPP) and water as a fat replacer in low-fat pork patties. Low-fat pork patties were developed by replacing the added fat with combinations of SPP and chilled water. Three different levels of SPP/chilled water viz. 0.5/9.5% (T-1), 1.0/9.0% (T-2), and 1.5/8.5% (T-3) were compared with a control containing 10% animal fat. The quality of low-fat pork patties was evaluated for physico-chemical (pH, emulsion stability, cooking yield, $a_w$), proximate, instrumental colour and textural profile, and sensory attributes. The cooking yield and emulsion stability improved (p<0.05) in all treatments over the control and were highest in T-2. Instrumental texture profile attributes and hardness decreased, whereas cohesiveness increased compared with control, irrespective of SPP level. Dimensional parameters (% gain in height and % decrease in diameter) were better maintained during cooking in the low-fat product than control. The sensory quality attributes juiciness, texture and overall acceptability of T-2 and T-3 were (p<0.05) higher than control. Results concluded that low-fat pork patties with acceptable sensory attributes, improved cooking yield and textural attributes can be successfully developed with the incorporation of a combination of 1.0% SPP and 9.0% chilled water.

The silver nanocrystalline is widely used for biological field because of its biocompatibility and anti-microbial effect. The objective of this study was to evaluate the therapeutic efficacy of the silver nanocrystalline ointment on the temporomandibular joint (TMJ) capsulitis. Total 39 patients were included in this study and all patients were received single topical application of the silver nanocrystalline ointment (group A, n=30) or placebo ointment (group B, n=19). Measured variables were maximum mouth opening (MMO), visual analog scale (VAS) for pain, and VAS for function. In results, we could not assess any therapeutic efficacy of single application in the chronic TMJ capsulitis (p>0.05). However, the single application of silver nanocrystalline ointment showed significant improvement in MMO and VAS for pain compared to placebo effect in the acute TMJ capsulitis (p<0.05). We could not find any complications related to ointment application in both groups. In conclusion, the single application of silver nanocrystalline ointment was effective in improving patient's symptom in acute TMJ capsulitis without any noticing complications.

The purpose of this study was to investigate differences in the value of children according to the demographic characteristics of mothers with young children. This was to examine the relationship between psychological and environmental factors, and the value of children to mothers with young children. The participants of this study were 237 mothers, who had young children. Descriptive statistics, t-test, F-test, and Pearson's correlation analysis were used for data analysis. The results were as follows: First, the value of children was different according to the child's factors (gender and number of children in the family, etc.), the mother's factors (age and education, etc), and the family's factors (household income and cost of bringing up the child). Second, familism is related to emotional value and instrumental value, parenting efficacy is related to emotional value and social value, children's temperament is related to emotional value, and the value of children from mother's reference group is related to emotional value and instrumental value, social value, and burdensome value. As for the implication of these findings, value of children from mother's reference groups is important for changing the value of children of the mothers with young children.

This study was conducted as a learning project for 20 pre-third graders in high school by means of math textbooks, G+, and sample questions from previous CSAT as learning tools for 9 weeks from Dec. 24, 2015. The purpose of the study was to develop 'math textbook project learning(MtPL)', a mixed learning method combined on-line with off-line, and analyze the effects of MtPL on the affective domain of high school students. As a result of the study, it was found that MtPL had positive effects on self-efficacy and self-confidence of students, while the collaborative learning using a textbook and teacher's role worked as instrumental motivation in mathematics learning. The result also implies that the perception of high school students, who think to resolve more difficult math problems to succeed in CSAT, about mathematics learning method has to be modified. Furthermore, it is shown that the preparation of CSAT by utilizing textbook and the use of textbook in math learning have been worked positively for the students.

Purpose: This study aims to identify the effect of university students' intention to donate hematopoietic stem cells based on the theory of planned behavior. Methods: The subjects include university students who visited the campaign for the registration of hematopoietic stem cell donation held at H university on September 28, 2019 and October 2, 2019. Results: The intention to register for hematopoietic stem cell donation and empirical attitude (r=.72, p<.001), instrumental attitude (r=.64, p<.001), directive norm (r=.53, p<.001), technical norms (r=.55, p<.001) and self-efficacy (r=.86, p<.001) showed a significant positive correlation. The multiple regression analysis revealed that self-efficacy (β=.66) and empirical attitude (β=.23) were the most influential factors. Conclusion: Educational and promotional programs to increase the intention to register for hematopoietic stem cell donation need to be developed to help increase students' self-efficacy and help them develop a positive experiential attitude. In addition, further research is needed to determine whether the intention to register in hematopoietic stem cell donation among university students can lead to actual registration and donation after registration.

Purpose: The purpose of this study was to develop a Korean version of the Falls Efficacy Scale (K-FES), which is used to measure the fear of falling, that is conceptually equivalent to the original and culturally adaptable to the Korean population. Methods: A five-step translation and adaptation process was employed to create the K-FES, adhering to the established guidelines for cross-cultural rehabilitation outcome measures. The content validity was then evaluated by 22 rehabilitation professionals (15 males and 7 females) with an average clinical experience of 201 months at neurological rehabilitation centers. The content validity ratio and index were used as a basis for judgment. Results: The translation process identified inconsistencies with the terms "objects" and "telephone" in the original Falls Efficacy Scale, which were subsequently resolved in the final K-FES version. The content validity ratios for the original, second, and third versions of the K-FES ranged from -0.27-0.91, -0.27-0.91, and -0.27-0.91, respectively. Correspondingly, the content validity index values for the original, second, and third versions of the K-FES ranged from 0.77-1.00, 0.68-1.00, and 0.63-1.00, respectively. Conclusions: The K-FES was rigorously developed through translation, adaptation, and validation processes, making it a reliable tool for Korean stroke rehabilitation professionals. It is expected to be instrumental in clinical and research settings to assess postural stability and fall risk in patients with strokes and brain injuries.

Upper extremity dysfunction is a common consequence following stroke. Spontaneous recovery during the first six months post-stroke is rigorous and considered as a significant indicator of potential long-term progress. Various approaches have been utilized to regain functional upper limb movement necessary for independent living; however, conventional therapy approaches have failed to prove consistency, especially for subacute stroke patients. There is, thus, a need for innovative therapeutic strategies that motivate stroke survivors to facilitate neural and functional recovery during the critical window immediately following stroke. The effect of music on physical enhancement has been frequently reported in the field of medicine as well as neurorehabilitation. The efficacy of rhythm on lower extremity deficits has been well established. Yet, the rationale for using instrumental music making enhancing subacute upper extremities rehabilitation is not clearly described to date. Based on the key mechanism of music as sensori-motor movement facilitator, this paper reviews previous empirical research that utilized music-based interventions for upper extremity rehabilitation for stroke patients, either in the form of receptive or expressive activity. This paper, further, focuses on the current research trends in subacute stroke upper limb rehabilitation and provides applicable rationale of using instrumental music playing.
