The present study aimed to evaluate the effects of high-intensity ultrasound (HIU) application on meat quality traits, sensory parameters, and the microstructure of semitendinosus muscle from Hanwoo cattle. The samples were treated in an ultrasonic bath (35 kHz) at an intensity of 800 W/cm² for 60 min, followed by aging at 1℃ for 0, 3, and 7 days. The application of ultrasound resulted in lower Warner-Bratzler shear force and higher myofibrillar fragmentation index values during the storage period. HIU also enhanced the tenderness, flavor, umami, and overall acceptability of cooked beef muscle. However, the electronic tongue evaluation results showed higher umami values in the control treatment on the seventh day of storage. The microstructure of sonicated meat showed disorganized myofibrillar architecture and swelling in the A-band region of sarcomeres during the storage period, which led to greater meat tenderness. The heatmap illustrated the high abundance of α-linolenic acid (C20:5n3) and eicosapentaenoic acid (C18:3n3) in sonicated meat samples on the third day of the storage. These results showed that HIU is a potential method for tenderizing and improving the sensory attributes of beef without compromising other quality aspects.

The purpose of this study was to evaluate the effects of using cervical spinal stabilization exercise for the improvement of pain intensity, cervical range of motion, neck disability index, reposition sense, muscle tenderness with chronic neck pain in private security. For 21 patients diagnosed with chronic cervical pain and divided into cervical spinal stabilization exercise group and postural correction exercise group. Each exercise was conducted for 8 weeks. Pain and neck disability index were measured before and after exercise using the visual analogue scale(VAS) and the neck disability index(NDI). Range of motion were measured electronic goniometer, muscle tenderness of upper trapezius ad sternocleidomatoid were measured algometer, reposition sense were measured reposition panel before and after exercise. After 8 weeks of exercise, the cervical stabilization exercise group pain and neck disability were significantly decreased(p<0.05). Also there was significant difference in both group(p<0.05). In addition, range of motion, muscle tenderness reduce rate, reposition sense were significantly increase as compared to the pre-post exercise in cervical stabilization exercise group(p<0.05). But there was no significantly difference in postural correction group before and after exercise(p>0.05). And there was significantly increase more cervical stabilization exercise group than postural correction exercise group in range of motion, muscle tenderness reduce, reposition sense. In summary, cervical spinal stabilization exercise is more effective in improving cervical range of motion, muscle pain, reposition sense in private security on chronic cervical pain patients, in reducing patients' pain and disability. It is an effective treatment to aid rehabilitation in these cases.

Objective: For improving meat quality especially tenderness, male cattle are usually castrated to removes both the testicles. This study was conducted to evaluate the effect castration method (half- and complete-castration) on meat yield and quality characteristics of Hanwoo male cattle. Methods: Thirty-two similar age (5.9 months) Hanwoo male calves were divided into: half-castration (HC) and complete-castration (CC) groups (n = 16 per group). At 7 months of age, all the animals were castrated in which the HC calves had only one testicle surgically removed while, the CC calves had both testicles surgically removed. The castrated animals were reared under identical conditions until 25 months of age. After slaughter, the carcasses were evaluated for carcass traits and meat yield of primal cuts. For examination of the castration effect on meat quality, L. lumborum and semimembranosus muscles were used. The meat samples were analyzed for chemical composition, color, pH, shear force and water holding capacity, fatty acids, metabolites and volatile aroma compounds. Results: The HC group showed higher meat yields of all primal cuts (p<0.05). As a result, the total meat yield was higher by approximately 44 kg in the HC group (303.32 kg, corresponding to 67.88%) compared to the CC group (259.30 kg, corresponding to 62.11%) (p<0.05). In terms of meat quality, the HC resulted in two times greater fat content in both muscles examined compared to intact males. More importantly, the shear force values did not differ between HC and CC groups for L. lumborum muscles (p>0.05). The meat from HC animals exhibited higher amount of free amino acids associated with sweetness (p<0.05). Furthermore, the castration method only exhibited a negligible effect on metabolites and volatile aroma compounds in the cooked meat. Conclusion: Half-castration emerged as an alternative practice to be used for increasing the yield and tenderness of male cattle meat.

Sensory traits and preferences regarding food co-product fermented liquid (FCFL)-fed pork loin were compared with those of formula-fed pork. The FCFL-fed pork was expected to have improved fat meltability. Thirty-nine laboratory panelists took part in a sensory test. The fat meat and the lean meat of FCFL-fed pig were judged more meltable and tender, respectively, than the corresponding meat from the formula-fed pig. These sensory traits agreed closely with the results of a mechanical investigation of fat melting patterns and with Warner-Bratzlar shear force values. However, the overall preference was not significantly associated with sensory fat meltability and meat tenderness, as assessed by chi-square and correspondence analyses, but it was significantly related to the whole fat preference and the fat texture preference. The fat texture preference, however, did not correlate with sensory fat meltability. These results indicated that FCFL feeding altered sensory fat meltability in pork loin, but the preference for such meltable fat differed among individual panelists.

The term thoracic outlet syndrome (TOS) is used to describe patients with compressed subclavian arteries, veins, and brachial plexuses in the region of the thoracic outlet. The objective of this study was to evaluate a scalenus stretching exercise that aims to restore normal function to patients with TOS. This study consisted of 60 patients with symptoms of TOS, and divided the patients into 3 groups: one that received manual therapy, one that practiced self stretching, and a control group. Each group consisted of 20 patients. This study assessed the efficacy of scalenus stretching exercise by examining the resting pain, tenderness, spherical grip power, and pinch grip power of patients. The data were analyzed using one-way ANOVA, Scheffe post hoc test, and independent t-test. The results showed that resting pain was statistically significant within the manual therapy and self stretching groups (p<.05), and that the resting pain of the manual therapy group was more statistically significant than that of the self stretching group (p<.05). Tenderness, spherical grip power, and pinch grip were statistically significant within the manual therapy and self stretching groups (p<.05), but there was no statistically significant difference between the two groups (p>.05). Finally I could see that there were no statistical differences between manual therapy and self stretching to improve the symptoms of the patients with TOS. These results imply that self stretching by patients is as important as manual therapy by a physical therapist.

Concerns about meat quality, including chicken meat, for the human diet has led to many attempts to manipulate the carcass fat and increase the eating quality. For actual eating quality, the birds must be grown and finished in a manner that results in meat that are tender, succulent and of good flavor, as well as being free from any foreign taint, flavor or safety hazard. Tenderization treatment with high voltage(820V) electrical stimulation and prechill muscle tensioning would improve the tenderness of chicken meat. Proper programs for the withdrawal of feed and water require a team approach for maximizing yield of meat and minimizing carcass contamination. Also effding of supplemental levels of-tocopherol to poultry with vegetable or fish oils increases of desirable polyunsaturated fatty acid(PUFA) content and stablizes the meat against rancidity and fish off-flavors. The nutritional effects of varying dietary ingredients on broiler carcass fat content are also important. Increasing the levels of energy in the ration increases the carcass fat content, while increasing the proteing levels decreases carcass fat content. Supplement-tation of poultry diets with amino acids such as methionine, lysine, glycine and tryptophan as well as amino acid such as well as amino acid mixtures can reduce body fat deposition. Normal stress leads to chicken muscular damage resulting in reduced meat quality, but this can be controlled by preslaughter management practices. Feed manufactures can utilize ntilize nutrient modulation to control pale soft exudative(PSE)syndrome. Finally, the success in poultry meat production depends on the consistent achievement of carefully selected levels of quality. Quality assurance should be the wider function of incorporating quality into the production system and the combination of motivating quality into actions and operations.

Tenderization of beef by the addition of barks(Morus alba Linne) and its sensory properties were observed by shearing test, cooking loss, pH, protein content and sensory evaluation. Shear force was decreased as the addition level of barks (Morus alba Linne) increased. Tenderization effect of beef was increased 8,8% at the addition level of 2.5%, 25% at 5.0%, 4.7% at 7.5%, 58% at 10% barks(Morus alba Linne). Cooking loss was observed 44.50% at the no addition, 45.3% at 2.5%, 45.8% at 5.0%, 47.5% at 7.5%, 50.0% at 10% addition level of barks (Morus alba Linne). As the addition level of barks(Morus alba Linne) increased pH of cooked beef decreased to the range of 5.6 to 5.46. As the addition level of barks (Morus alba Linne) increaed protein content of beef decreased whereas protein content of cooled liquor increased. The addition of barks(Morus alba Linne) improved the sensory quality of cooked beef. Especially, tenderness scored the highest value in 10% added beef and other quality factors color, flavor, juiciness and overall quality were evaluated significantly high in 5% added beef. Therefore 5% addition level of barks(Morus alba Linne) for cooking beef was suggested as the desirable level of addition.

Shigella infection usually produces gastrointestinal symptoms but rarely causes urinary tract infection. A 7-year-old girl was admitted for fever, chills, right flank pain, and dysuria. She had no vomiting or diarrhea. There was mild tenderness in her right lower abdomen, and right CVA tenderness was also noted. Acute pyelonephritis was diagnosed by abdominal CT. She showed improvement with intravenous administration of antibiotics. The first urine culture grew $1{\times}10^5$ CFU/mL Shigella dysenteri. Although urinary tract infections due to Shigella species are extremely rare, Shigella species should be considered as a possible cause of pediatric urinary tract infection. We report the first case of urinary tract infection caused by S. dysenteri, which presented as acute pyelonephritis without gastrointestinal symptoms in a child.
