The spatial distribution of alleles and geographical distances of a Carex humilis population on Mt. Giri in Korea were studied. A total of 102 DNA fragments (bands) were found among 107 plants. Among these 102 bands, 48 (47.1%) bands were polymorphic. In a simple variability of subpopulations by the percentage of polymorphic bands, distances I and V exhibited the lowest variation (16.7%). Distance VIII showed the highest variation (22.6%). The total genetic diversity (H) was 0.076 across species. Class VIII had the highest H (0.093), while class I had the lowest (0.063). Genetic similarity of individuals was found among subpopulations at up to a scale of 60 m distance, and this was partly due to a combination of alleles. Within the Mt. Giri population, a strong spatial structure was observed for RAPD markers, indicating a very low amount of migration among subpopulations and that the distribution of individual genotypes of a given population was clumped. The present study demonstrated that analysis of RAPD markers could be successfully used to study the spatial and genetic structures of C. humilis.

Purpose: We examined tobacco use pattern and its correlates among older adults. Materials and Methods: We used data of 9,852 older adults (${\geq}60$ years) (men 47% mean age 68 years) collected by the United Nations Population Fund on Ageing from seven Indian states. Logistic regression analysis was used to assess the correlates of tobacco use. Results: Current use of any form of tobacco was reported by 27.8% (men 37.9%, women 18.8%); 9.2% reported only smoking tobacco, 16.9% smokeless tobacco only and 1.7% used both forms. Alcohol users (OR:5.20, 95% CI:4.06-6.66), men (OR:2.92, CI :2.71-3.47), those reporting lower income (OR:2.74, CI:2.16-3.46), rural residents (OR 1.34, CI 1.17-1.54) and lower castes (OR:1.29, CI:1.13-1.47) were more likely to use any form of tobacco compared to their counterparts. Conclusions: Tobacco cessation interventions are warranted in this population focusing on alcohol users, men, those from lower income, rural residents and those belonging to a lower caste.

This study evaluated and compared the effectiveness on upper motor extremity function between proprioceptive neuromuscular facilitation which has been frequently used in clinical practice, and action observation training in terms of improving upper motor extremity function. A study with a single-subject design (A-B-C-A') was conducted with a patient who was diagnosed with left hemiplegia. A repeated-measure analysis was conducted to assess results of the Wolf Motor Function Test (WMFT), Box and Block Test (BBT), and grip and pinch strength test performed daily in the study for 4 weeks. The results of the analysis indicated that the WMFT score, BBT score, grip strength, and pinch strength were improved from 29.60 to 39 (24.10%), from 1.67 to 4.93 each (EA) (66.22%), from 2.06 to 2.66 libras (lbs) (22.61%), and from 1.57 to 1.93 lbs (18.94%), respectively, from the baseline period to treatment period B. The values were improved from 29.60 to 42.20 (29.86%), from 1.67 to 7 EA (76.21%), from 2.06 to 3.47 lbs (40.57%), and from 1.57 to 1.67 lbs (6.12%), respectively, from the baseline period to treatment period C. From treatment period B to treatment period C, the WMFT score, BBT score, and grip strength were improved from 39 to 42.20 (7.58%), from 4.93 to 7 EA (29.56%), and from 2.66 to 3.47 lbs (23.20%), respectively, but pinch strength was decreased from 1.93 to 1.67 lbs (15.83%). In conclusion, proprioceptive neuromuscular facilitation and action observation training both have positive effects on upper extremity motor function. However, we suggest that the posttreatment effect of action observation training was better than that of proprioceptive neuromuscular facilitation.

This study aims to investigate the awareness and needs of patients as consumers and therapists as providers on the introduction of home physical therapy in the long-term care insurance. The survey participants were 96 patients and 132 physical therapists to a questionnaires, we analyzed for frequency of each questionnaire about awareness and necessity. As a result of the test, they considered that physical activity support services provided by nurse and nurses aid ware not specialized enough(pt 60,4%, PT 75,4%) and quality therapy should be available through a home physical therapy(pt 47.9%, PT 59.2%). Also, patients responded that the priorities to improve long-term care insurance were given to lowering expenses(35,4%) and expanding coverage of subjects(32.3%) while the physical therapists responded that professionals should be expanded(73.8%) and diverse rehabilitation services(20.2%) and a rehabilitation team should be introduced. They responded that the reasons of home physical therapy were needed that it was hard for patients to visit medical centers(PT 30.0%) themselves and it would be improvable for them to get physical function in elderly(pt 47.1%) through the service. In conclusion, as most patients as well as physical therapists responded that home visit therapy services should be introduced and their awareness of it was very high, it is suggested that the service should be quickly introduced as soon as possible.

Purpose: To determine clinical results for arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique. Materials and Methods: Between November, 2007 and October, 2008, we evaluated 90 cases of arthroscopic middle, large rotator tear cuff repair. The mean follow-up period was 15 months (range, 12-23 months). Forty-three cases had medium-sized tears; 47 cases had large-sized tears. At the preoperative stage and again at last follow-up, functional results were assessed by the KSS, ASES, UCLA and the PVAS (Pain visual analogue score). Results: Pain score improved from 2.56 preoperatively to 0.96 at final follow-up; movement scores improved from 6.94 to 1.70. At. final follow-up, the average UCLA score improved from 17.08 to 31.17 with 31 excellent (34%), 49 good (54%) and 10 poor results (12%). The final UCLA score was 31.47 in the group less than 60 years of age and 30.69 in the group over 61 years of age (p=0.344). The UCLA score was 31.23 in those with medium-sized tears and 31.11 in those with large-sized tears (p=0.924). The UCLA score was 31.10 in non-trauma patients and 31.23 in trauma patients (p=0.929). Conclusion: Arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique can produce excellent clinical results. These outcomes are not affected by age or trauma history.

Echinostoma mekongi was reported as a new species in 2020 based on specimens collected from humans in Kratie and Takeo Province, Cambodia. In the present study, its metacercarial stage has been discovered in Filopaludina martensi cambodjensis snails purchased from a local market nearby the Tonle Sap Lake, Pursat Province, Cambodia. The metacercariae were fed orally to an experimental hamster, and adult flukes were recovered at day 20 post-infection. They were morphologically examined using light and scanning electron microscopes and molecularly analyzed by sequencing of their mitochondrial cox1 and nad1 genes. A total of 115 metacercariae (1-8 per snail) were detected in 60 (60.0%) out of 100 Filopaludina snails examined. The metacercariae were round, 174 ㎛ in average diameter (163-190 ㎛ in range), having a thin cyst wall, a head collar armed with 37 collar spines, and characteristic excretory granules. The adult flukes were elongated, ventrally curved, 7.3 (6.4-8.2)×1.4 (1.1-1.7) mm in size, and equipped with 37 collar spines on the head collar (dorsal spines in 2 alternating rows), being consistent with E. mekongi. In phylogenetic analyses, the adult flukes showed 99.0-100% homology based on cox1 sequences and 98.9-99.7% homology based on nad1 sequences with E. mekongi. The results evidenced that F. martensi cambodjensis snails act as the second intermediate host of E. mekongi, and hamsters can be used as a suitable experimental definitive host. As local people favor to eat undercooked snails, these snails seem to be an important source of human infection with E. mekongi in Cambodia.

Background: This study examined the changes in the leg muscle activities of 30 healthy subjects according to different pressures caused by isometric hip adduction during squat exercise. Methods: With their knee flexed at 60°, the subjects performed isometric hip adduction with a pressure of 0, 20, 40, and 60mmHg. Surface electromyography was used to measure their muscle activities. Changes in the activities of the muscles, such as the gluteus maximus (GMAX), Gluteus medius (GM), vastus medialis oblique (VMO), vastus lateralis oblique (VLO), biceps femoris (BF), and Tensor fasciae latae (TFL) muscles, were analyzed. Results: The activities of the VMO, VLO, GM, BF, and GMAX muscles were significantly different after exercise compared to that before exercise (p<.05). The activities of all the leg muscles measured were highest at a pressure of 60mmHg during isometric hip joint adduction. Conclusion: The pressure produced by isometric hip joint adduction during squat exercise increased the leg muscle activities of the subjects. These results will provide basic data on effective squat exercise to alleviate knee joint diseases.

Vitis hybrid (Sheridan)-Robus coreanus red wine was vinified by fermentation of a mixture of Vitis hybrid and Robus coreanus must at $25^{\circ}C$ for 10 days. The Vitis hybrid-Robus coreanus red wine had ethanol contents of 10.9%. It had high antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity of 57.8% and antioxidant activity of 64.8%. Changes in the physicochemical properties and functionality of the Vitis hybrid-Robus coreanus red wine was investigated during a post-fermentation period of three months. The ACE inhibitory activity of the red wine increased as the post-fermentation period prolonged, and showed the highest ACE inhibitory activity of 70.4% 60 days post-fermentation. However, the antioxidant activity declined significantly to 47.2% during the post-fermentation period of 60 days. In terms of sensory evaluation, the Vitis hybrid-Robus coreanus red wine had the best acceptability 60 days post-fermentation.
