Background: Stroke often results in impaired postural control and asymmetric weight distribution, which negatively affect balance and functional mobility. Previous research has demonstrated that balance training interventions incorporating proprioceptive stimulation and visual feedback can enhance postural stability in stroke survivors. However, there remains debate regarding the relative effectiveness of these two approaches. While proprioception-based training emphasizes sensory input from mechanoreceptors to improve postural control, visual feedback-based training leverages external cues to facilitate balance adjustments. Objectives: To investigation the effects of proprioception-based trunk exercise and visual-auditory feedback-based trunk exercise on sitting balance in patients with chronic stroke. Design: Randomized controlled trial. Methods: A total of 24 participants diagnosed with chronic stroke were randomly assigned to two groups: the proprioception-based trunk exercise group (PTG, n=10) and the visual-auditory feedback-based trunk exercise group (VTG, n=11). Both groups participated in a 6-week intervention program, five sessions per week, lasting 25 minutes per session. Outcome measures included the Limitation of Stability (LOS), the Korean version of the Trunk Impairment Scale (K-TIS), and the Postural Assessment Scale for Stroke (PASS). Pre- and post-intervention assessments were analyzed using paired t-tests and independent t-tests to evaluate within-group and between-group differences. Results: Both PTG and VTG groups demonstrated significant improvements in LOS, K-TIS, and PASS scores following the intervention (P<.05). However, there were no statistically significant differences between the two groups in the amount of change observed. Conclusion: The findings suggest that both proprioception-based and visualauditory feedback-based trunk exercises are effective in improving sitting balance in chronic stroke patients. The lack of a significant difference between the groups indicates that both approaches provide comparable benefits. Future research should explore long-term effects and investigate potential differences in various functional domains beyond sitting balance.

Background: Neck discomfort and movement limitations are common musculoskeletal problems among modern people. While cervical and thoracic joint mobilization are widely used interventions for cervical dysfunction, research comparing their immediate effectiveness in adults with asymmetrical cervical rotation is limited. Objectives: To compare the immediate effects of cervical versus thoracic joint mobilization in adults with adults with asymmetrical cervical rotation and discomfort. Design: Randomized controlled trial. Methods: Thirty adults with left-right differences in cervical rotation of more than 5 degrees were randomly assigned to a cervical mobilization group (CMG, n=15) or thoracic mobilization group (TMG, n=15). Both groups received Grade III mobilization for 15 minutes. Range of motion (ROM), pain (VAS), and neck disability index (NDI) were measured before and after intervention. Results: Both groups showed significant increases in ROM after intervention (P<.001). Within-group analysis revealed that the TMG showed significant pain reduction (P<.01) and significant reduction in left-right rotation asymmetry (P<.001), while the CMG showed improvement in ROM but no significant changes in asymmetry or pain (P>.05). Neither group showed significant changes in NDI. Between-group comparisons showed no significant differences in any outcome measures. Conclusion: Both cervical and thoracic joint mobilization increased cervical range of motion in adults with asymmetrical cervical rotation discomfort. The TMG demonstrated significant within-group improvements in left-right rotation asymmetry and pain reduction, suggesting potential clinical benefits of thoracic mobilization for certain aspects of cervical dysfunction.

Background: Functional sarcopenia, a subcategory of sarcopenia, has recently been introduced. It is defined by muscle weakness and reduced physical performance, regardless of muscle mass reduction, and may potentially affect overall rehabilitation outcomes in patients. Objectives: This study aimed to classify stroke patients into two groups based on the presence or absence of functional sarcopenia and to compare changes in balance and gait ability after receiving the same rehabilitation intervention. Design: A quasi-experimental design. Methods: A total of 44 stroke patients participated in this study and were classified into functional sarcopenia (n=22) and non-functional sarcopenia groups. Physical function tests were used to assess balance (Timed Up and Go, Berg Balance Scale) and gait (10-Meter Walk Test, Functional Ambulation Category). All participants underwent a four-week convalescent rehabilitation program, receiving five sessions per week, with each session lasting four hours per day. Results: After four weeks of convalescent rehabilitation, both groups showed significant improvements in all outcome measures (P<.05). However, when comparing the pre-post changes, no significant differences were found between the two groups in the changes of balance and gait outcomes (P>.05). Conclusion: These findings suggest that stroke patients with functional sarcopenia can achieve a similar level of functional recovery as those without functional sarcopenia when provided with appropriate rehabilitation interventions.

Background: Prolonged use of computers and mobile devices has contributed to postural abnormalities such as Rounded Shoulder Posture (RSP), which is characterized by muscle imbalances that can lead to pain and functional limitations. Correcting these imbalances through targeted stretching and strengthening exercises was expected to help improve postural alignment and muscle function. Objectives: This study aimed to investigate the effects of a six-week integrated exercise program targeting the pectoralis minor (PM), upper trapezius (UT), and lower trapezius (LT) on postural alignment and muscle activation in female adults with RSP. Design: Single-group pre-post test study. Methods: Eighteen female university students (aged 20–22 years) with RSP participated in a six-week intervention consisting of PM stretching, UT stretching, and LT strengthening exercises. RSP severity was assessed using acromion-to-ground distance, PM length was measured with a caliper, and surface electromyography (sEMG) was used to evaluate UT and LT muscle activity. Normality was verified using the Shapiro-Wilk test, and paired t-tests were conducted for statistical analysis (α=0.05). Results: After the intervention, significant improvements were observed in all measured variables. Acromion-to-ground distance decreased (P<0.001), PM length increased (P<0.001), UT activation decreased (P<0.01), and LT activation increased (P<0.01). Conclusion: The six-week integrated exercise program effectively improved postural alignment and muscle activation in women with RSP by addressing muscle shortening, overactivity, and weakness. These findings suggest that combined stretching and strengthening exercises can serve as a practical and effective approach for RSP correction. Future studies with longer durations and diverse populations are recommended to further validate these results and enhance clinical applicability.

A new spider species of the genus Pholcus Walckenaer, 1805, Pholcus osaek sp. nov., in the family Pholcidae C.L. Koch, 1850, is described from Korea. This new species belongs to phungiformes-group in the genus. It can be distinguished from its congeners by the shape and structure of genital organs of both males and females. It is found on and between rock walls in mountainous mixed forests. Additionally, the taxonomic status of Pholcus uksuensis Kim & Ye, 2014 is revalidated, re-diagnosed, and redescribed based on specimens collected from the type locality. Considering differences mentioned in the diagnosis through revalidation, P. uksuensis is regarded as a distinct species. Therefore, it should be removed from the synonymy of P. woongil Huber, 2011.

This study was conducted to investigate the effects of feeding DDGS and full-fat soybean in the finishing diet on the performance, carcass characteristics and unsaturated fatty acid composition of Hanwoo steers. Thirty Hanwoo steers (average age, 26.4 months; weight, 756.69 kg) were assigned into Control (no additive), DS (DDGS supplemented) and FS (full-fat soybean supplemented). The feeding rate of DDGS and full-fat soybean was set at 10% and 5% in the finishing diet, respectively, and the in vivo trial was conducted for 122 days. The final body weight was 779.81, 774.20 and 791.95 kg for Control, DS and FS, respectively, and the average daily gain was not different among treatments. The feed conversion ratio was lower in FS compared to Control. Carcass cold carcass weight, backfat thickness, M. longissimus dorsi area and marbling scores were not different among treatments, and moisture, crude protein, and crude fat content in carcass were not different. The melting point of sirloin ranged from 25 to 26℃ among treatments. The saturated fatty acid, C18:0, was lower in the FS than in Control. C18:1, the main unsaturated fatty acid (UFA) in carcasses, did not show any difference among treatments, but C18:2 was higher in DS than in Control. Total UFAs were higher in the FS than in Control. Based on the above results, DDGS feeding was effective in improving feed conversion ratio and C18:2 content, and full-fat soybean feeding was effective in improving feed conversion ratio and increasing UFA content.

This study assessed the effects of fescue toxicosis on ruminal metabolism and physiology in steers. Twelve ruminally cannulated Angus steers [body weight (BW) = 547 ± 9 kg] were blocked by BW and randomly assigned to six blocks. The steers were fed alfalfa cubes (1.5× NEm) and dosed (1 kg/d) with either endophyte-infected tall fescue seed (E+) or endophyte-free tall fescue seed (E-) via rumen cannula for 21 days. Ruminal dry matter (DM) content was tended to have a higher (p=0.052) in steers in E+ than in E- group. Total volatile fatty acid (VFA), acetate concentrations, as well as the acetate:propionate ratio, were higher (p=0.084, 0.095, and <0.001, respectively) in the E+ group, while propionate was lower (p<0.001). Ruminal pH and temperature were similar between treatment groups (p=0.62 and 0.95, respectively), but ruminal pressure was higher (p<0.001) in E-. Additionally, serum prolactin levels was lower (p<0.001) in the E+ group. These findings suggest that consumption of endophyte-infected tall fescue seed may impair ruminal VFA absorption, potentially due to changes in ruminal motility.

This study conducted to investigate potential differences in the activity of genes involved in volatile fatty acid (VFA) absorption, pH regulation, and energy metabolism in epithelial cells of forestomach administered either endophyte-infected (E+; 4.45 mg ergovaline/kg) or endophyte-free (E−) tall fescue seed. Twelve steers [body weight (BW) = 547 ± 9 kg] were fed alfalfa cubes at 1.5 × NEm and dosed 1 kg of ground tall fescue seed daily via rumen cannula for 21 days. On day 22, steers were slaughtered, and tissue samples were collected from the rumen, reticulum, omasum, and abomasum. Gene expression analysis revealed that monocarboxylate transporters (MCT), isoform 1 and MCT4 expression levels were significantly lower (p<0.05) in the rumen epithelium of steers dosed with E+ seed, while MCT2 expression remained unchanged. Similarly, sodium hydrogen exchanger (NHE), isoform 2 expression was significantly reduced (p<0.05) in the E+ seed, whereas NHE1 and NHE3 were unaffected by the seed treatment. Additionally, expression levels of down regulated in adenoma (DRA) and anion exchanger (AE), isoform 2 were lower (p<0.05) in the rumen epithelium of E+ steers, while putative anion transporter 1, sodium bicarbonate cotransporter, isoform 1, 3-hydroxy 3-methylglutaryl coenzyme A synthase, isoform 2, and sodium potassium ATPase pump, isoform 1 expression levels were not influenced by the seed treatment. Notably, gene expression in the reticulum, omasum, and abomasum epithelia was unaffected (p>0.05) by seed exposure. These findings suggest that endophyte-infected tall fescue seed may impair ruminal VFA absorption in its dissociated state (pH > 5.8) by downregulating MCT1 and MCT4, along with suppressing NHE2, DRA, and AE2. Therefore, this mechanism may partially explain the reduced weight gain associated with fescue toxicosis in cattle.

본 연구에서는 국내에서 처음 발견된 Aulacophoroides hoffmanni (Takahashi, 1937)를 최초로 보고한다. 2024년 야외조사에서 한국의 서부 2개 지역의 등나무(Wisteria floribunda (Willdenow))에서 심각한 피해를 주고 있는 A. hoffmanni를 확인하였다. 무시성충의 상세한 형태 기재와 계측값을 제시하였으며, 생체 및 슬라이드 표본 사진을 포함하였다. 이 종은 등나무에 심각한 피해를 주고 있어 관상용 등나무의 주요 해충이 될 것으로 예상된다.

This study aimed to evaluate the effects of different feeding levels of domesticated barnyard millet and imported Bermuda hay on the growth performance and structural development of female and male growing goats. A 4×4 Latin square design was used, involving 8 goats with an average age of 3 months: 4 females and males with an initial body weight (BW) of 10.6 kg and 16.0 kg, respectively. Goats were randomly assigned to 4 dietary treatments: T1 (1.5% BW barnyard millet), T2 (1.5% BW Bermuda hay), T3 (2.0% BW barnyard millet), and T4 (2.0% BW Bermuda hay) over a 22-week period. Results indicated that the highest final body weight (FBW) was significantly observed at the highest feeding level (T4), with females reaching 14.9 kg and males 20.9 kg, while the highest average daily gain (ADG) values were recorded for females in T3 at 75.7 g/d and males in T4 at 81.0 g/d (p<0.05). Dry matter intake (DMI) was highest in the T4 group for both females (437.4 g/d) and males (635.9 g/d), with significant differences observed across treatments (p<0.05), whereas the feed conversion ratio (FCR) showed an improving trend, particularly with a value of 6.0 for females in T4. For structural development, the highest feeding levels led to significant increases in body length, body depth, chest width, and chest girth of both sex. Female and male in T4 achieved body lengths of 53.5 cm and 61.8 cm, and body depths of 45.2 cm and 54.8 cm, respectively. Chest width and girth reached 15.9 cm and 66.5 cm in males, and 13.5 cm and 56.5 cm in females. In conclusion, higher feeding levels, especially with Bermuda hay, may positively influence the growth performance and structural development of goats.

The role of the gut microbiota in colorectal cancer (CRC) development has garnered attention, highlighting probiotics as potential adjuncts in CRC prevention and treatment. In recent years, probiotics and their derivatives have demonstrated mechanisms that may contribute to anticancer properties. This study investigates the cytotoxic effects of Bifidobacterium bifidum KCTC 3357, Lacticaseibacillus rhamnosus KCTC 5033, Limosilactobacillus reuteri VA 103, Bacillus galactosidilyticus VA 107, and Lactococcus taiwanensis VE101 on CT-26 mouse colon carcinoma cells using live cells, heat-killed cells (paraprobiotics), and cell-free supernatants (CFS, postbiotics) through an MTT assay. The results indicate that live bacterial strains, such as KCTC 3357, VA 103, and VA 107, promoted CT-26 cell viability, while heat-killed cells and CFS exhibited dose-dependent cytotoxicity. Inactivated forms of KCTC 3357 and VE 101, as well as CFS at 10 mg/mL concentration of KCTC 5033, VA 103, and VE 101, showed the strongest antiproliferative effects. These findings suggest that non-viable probiotic derivatives, such as paraprobiotics and postbiotics, offer promising therapeutic potential for CRC, providing a safer and more stable alternative to live probiotics. However, further research is required to explore their mechanisms of action, in vivo efficacy, and potential clinical applications.

This study explored factors affecting variability in second language (L2) learning motivation among Korean university students and how they appraised their L2 learning experience. In this study, 85 undergraduate students majoring in English or English education from three universities in Seoul, South Korea, reflected on their past English learning experience. They drew a motigraph and wrote a retrospective reflection essay covering their English learning that spanned over ten years. Researchers divided participants into two groups: a high variability (HV) group and a low variability (LV) group. Data were analyzed using open, axial, and selective coding. Findings suggest thncontextual factors such as the learning method, atmosphere, and situation were main (de)motivational factors for the HV group. In contrast, the LV group was (de)motivated by intrapersonal factors, including the learning context appraisal. These results imply that visualizing long and short-term goals and positive appraisal of the L2 learning experience can help L2 learners maintain a stable pattern in L2 learning motivation.

Oral cancer has a high mortality rate, making early diagnosis crucial for effective treatment and prognosis. Unlike other cancers, oral cancer develops in the oral cavity, enabling direct contact between saliva and cancer cells. Therefore, saliva is a more useful diagnostic tool than serum or tissue. When DNA, RNA, or proteins produced by cancer cells enter the saliva, they can be easily detected as tumor markers. Therefore, salivary biomarkers can serve as a noninvasive alternative to serum- or tissue-based biomarkers. Early diagnosis is essential for increasing the treatment success rate, improving prognosis, and enhancing post-treatment recovery, ultimately improving the quality of life. Proteins are essential molecules involved in key processes, such as the development, growth, death, and metastasis of oral cancer. Recent advancements in molecular biology and salivary proteomics have enabled the detection and analysis of numerous proteins in saliva. Many of these protein molecules are currently the focus of extensive research. This article aims to review the potential of saliva as a diagnostic tool, techniques for detecting protein biomarkers, and salivary protein biomarkers for oral cancer diagnosis.

본 연구는 프랑스와 영국의 탈식민주의 방법론을 비교하며, 유럽중심 주의, 재현(representation), 지식 생산에 대한 접근 방식을 살펴보았다. 문헌분석과 비교방법론을 사용하여, 존재론적이고 마르크스주의적 전통 에 뿌리를 둔 프랑스의 사유가 체계적인 비판을 강조하는 방식, 특히 에 메 세제르(Aime Cesaire)와 프란츠 파농(Frantz Fanon) 등의 탈식민화 와 저항을 조망하였으며, 에드워드 사이드(Edward Said), 가야트리 스피 박(Gayatri Spivak), 호미 바바(Homi Bhabha) 등의 이론을 통해 문화 연구, 페미니즘 이론, 탈구조주의에 영향을 받은 영국의 포스트식민주의 이론이 상징적이고 교차적인 역학, 재현과 ‘하위’로 분류되는 사람들의 주변화에 중점을 두는 관점을 탐구하였다. 연구 결과 양국 이론의 전통 이 가진 강점과 한계를 알 수 있었으며, 프랑스의 접근은 구조적 식민주 의를 비판하는 데 중점을 두지만 영국의 접근은 상징적이고 재현적인 메 커니즘을 해체하는 데 초점을 맞추고 있음을 밝힐 수 있었다. 이러한 관 점들의 통합을 통해 이 연구는 탈식민주의에 대한 전체론적 비판을 위한 융합적 틀을 제시하며, 탈식민지 연구가 지식의 탈식민화와 주변화된 목 소리의 증폭이라는 사명을 진전시킬 수 있음을 제언하였다. 특히, 이 두 전통의 융합이 식민주의가 남긴 물질적·상징적 억압을 통합적으로 이해 하는 데 기여할 수 있음을 제시하였다. 이 연구는 이러한 전체적 접근이 단순히 과거의 식민지 경험을 분석하는 것을 넘어, 디콜로니얼을 향한 탈식민시대와 미래의 지식 체계와 학문적 실천을 재구성하는 데 중요한 학문적 함의를 가진다.

This study analyzes the visual image effects regarding the design changes of sleeves and shoulders on plus-size women in their 20s and 30s to propose ideas for plus-size women’s clothing production and design. Based on a plus-size women’s basic raglan sleeve shirt, six types of raglan sleeve shirts with various design elements were developed using a 3D virtual imaging program to analyze the visual image effect of each pattern’s features. The results showed that the A-shaped sleeve silhouette, exemplified by Pattern A2, makes the upper body look longer and slimmer as a whole. It also conveyed a sense of refinement and attractiveness, displaying positive effects regarding body shape and aesthetic perception. Meanwhile, O-shaped silhouettes, such as Pattern B1 and Pattern B2, showed positive effects regarding comfort and mobility, while Y-shaped silhouettes, such as Pattern C1 and Pattern C2, created a visually confident appearance. Furthermore, the research examined the effects of static images and dynamic videos on evaluation outcomes. The results showed that dynamic images enhanced immersion and vibrancy, thereby increasing focus on the apparel evaluated. The results of the visual image evaluation can be used as a basis for designing not only raglan sleeves but also overall sleeve shapes.

Galaxy evolution studies require the measurement of the physical properties of galaxies at different redshifts. In this work, we build supervised machine learning models to predict the redshift and physical properties (gas-phase metallicity, stellar mass, and star formation rate) of star-forming galaxies from the broad-band and medium-band photometry covering optical to near-infrared wavelengths, and present an evaluation of the model performance. Using 55 magnitudes and colors as input features, the optimized model can predict the galaxy redshift with an accuracy of σ(Δz/1+z) = 0.008 for a redshift range of z < 0.4. The gas-phase metallicity [12 + log(O/H)], stellar mass [log(Mstar)], and star formation rate [log(SFR)] can be predicted with the accuracies of σNMAD = 0.081, 0.068, and 0.19 dex, respectively. When magnitude errors are included, the scatter in the predicted values increases, and the range of predicted values decreases, leading to biased predictions. Near-infrared magnitudes and colors (H, K, and H −K), along with optical colors in the blue wavelengths (m425–m450), are found to play important roles in the parameter prediction. Additionally, the number of input features is critical for ensuring good performance of the machine learning model. These results align with the underlying scaling relations between physical parameters for star-forming galaxies, demonstrating the potential of using medium-band surveys to study galaxy scaling relations with large sample of galaxies.

Background: Multiple fractures, particularly femoral fractures, are increasingly prevalent and associated with high mortality rates and significant functional impairments. This highlights the urgent need for effective rehabilitation strategies, such as robot-assisted training, to enhance recovery and improve quality of life. Objectives: This study aimed to evaluate the clinical effectiveness of robotassisted rehabilitation for multiple femoral fractures. Design: Single-subject design. Methods: A 15-day A-B-A' single-subject design was employed. A man in his 30s with multiple fractures underwent standard rehabilitation during the baseline (A) and regression baseline (A') phases, with robotic therapy introduced during the intervention phase (B). Daily assessments of mobility and balance were analyzed using the two-standard deviation method. Results: Robotic therapy led to significant improvements: the TUG test time decreased from 16.21±0.64 seconds (A) to 10.63±0.46 seconds (B) and 9.64±0.35 seconds (A'). The 10 MWT time improved from 6.31±0.64 seconds (A) to 5.41±0.17 seconds (B) and 5.01±0.12 seconds (A'). LOS increased from 364.01±35.83 cm² (A) to 484.67±29.97 cm² (B) and 518.03±18.82 cm² (A'). Plantar pressure imbalance (59.2% right, 40.8% left in A) was corrected to nearly equal distribution in B (49.4%/50.6%) and A' (50.8%/49.2%). Conclusion: Robotic rehabilitation therapy improves balance and weightbearing capacity in patients with multiple fractures, suggesting its effectiveness as an early intervention following bone union.

Background: Chronic ankle instability (CAI) is very common disease. Strength exercise, balance exercise, and proprioceptive exercise were used to improvement of function for CAI. Isokinetic strength and balance are related to functional movement of lower extremity. Objectives: The purpose was to analyze the effect of muscle strengthening exercise, balance exercise, and proprioceptive exercise on isokinetic strength and balance in young adults with CAI. Design: Randomized controlled trial. Methods: The subjects were 30 young adults with CAI. The subjects randomly divided into three groups: strengthening exercise, balance exercise, and proprioceptive exercise. They performed each exercise for 20 minutes, three times a week for four weeks. They measured isokinetic strength of dorsiflexor and plantar flexor of 60°/sec and 120°/sec, static and dynamic balance before and after exercise. Results: The isokinetic strengths of dorsiflexor and plantar flexor of 60°/sec and 120°/sec were significantly higher in the strengthening exercise group than in the balance exercise group. The static and dynamic balance was significantly higher in the balance exercise group than in other two groups. Conclusion: Strengthening exercise, balance exercise, proprioceptive exercise can improve the muscle strength for CAI. Strengthening exercise and balance exercise can more improve balance than proprioceptive exercise for CAI.
