The number of livestock that is being raised worldwide is increasing every year due to the increase of human meat consumption. In Korea, the number of breeding numbers is steadily increasing every year due to the high rate of intensification and massification. However, in order to prevent further spread of livestock infectious diseases immediately after the outbreak of foot-and-mouth disease and avian influenza, large-scale burial of livestock was carried out in a short period of time. As a result of inadequate land- Pollution is occurring. Incineration and other treatments are difficult in reality due to domestic livestock environment conditions, so they are mostly processed according to buried method. In this study, the animal carcass (chicken and duck) with a moisture content of about 70% were dried with microwave at the final function rate of about 10~20% to solve the problem using mobile incineration method of burial method. It is meaningful to make it a porous solid fuel that is easy to incinerate animal carcass in order to fundamentally solve the environmental pollution by drying them. In addition, this study examined problems caused by butchery animal treatment and conducted a recognition survey on 1,000 adult consumers nationwide about the treatment of livestock with diseases. Therefore, it would be necessary to develop an effective treatment method for animal carcass considering the resources of animal carcasses.

The purpose of this study was to develop synbiotic materials and to apply them to the puffed grain products using electrostatic spraying technology. Lactic acid bacteria were isolated from Kimchi and selected through tests of acid resistance, bile salt resistance and γ-aminobutyric acid (GABA) content. The isolated Lactobacillus brevis CFM21 produced highest GABA production up to a concentration of 926.42 μg/mL when grown in MRS broth containing 0.8% MSG. The possibility of coated grains as a prebiotic material was evaluated Confocal laser scanning micro scopy (CLSM). Rice bran extract containing 2% dextrose, 2% soytone, 0.2% potassium chloride, 0.6% MSG was produced 524.77 μg/mL of GABA. Citrus sinensis oil showed the highest antibacterial activity against Clostridium perfringens Electrostatic spray showed much higher effectiveness than conventional spray in coating the puffed grain product through CLSM. Applying Rice bran culture and Citrus sinensis oil to puffed grain product using electrostatic spray could contribute to promote intestinal health of consumers.

Background: Individuals with forward head posture (FHP) have neck pain. To correct the FHP, a posture correction band is commonly used. However, we do not know the posture correction band influenced the pulmonary function in individuals with FHP. Objects: This study aimed to elucidate the effects of the posture correction band on the pulmonary function in young adults with neck pain and FHP and to monitor how the pulmonary function changed over time. Methods: Twenty subjects with chronic neck pain and forward head posture were recruited. Subjects performed pulmonary function test four times: before, immediately, and 2 hours after wearing the postural band, and immediately after undressing the postural band. Vital capacity (VC), forced vital capacity (FVC), peak expiratory flow (PEF), and forced expiratory volume at one second (FEV1) were measured. The modified Borg dyspnea scale was used to measure each subject’s responses to the posture correction band. The mixed-effect linear regression was used to the effect of the posture correction band over time. Results: There were no significant differences in VC, FVC, PEF, FEV1 values over time (p > 0.05), although all values slightly decreased after applying posture correction band. However, the score of the modified Borg scale significantly changed after wearing the postural bands (p < 0.05), indicating the subject felt discomfort with posture correction band during breathing. Conclusion: Because the posture correction band did not change the pulmonary function over time, but it induces psychological discomforts during breathing in people with FHP. Therefore, this posture correction band can be used for FHP realignment after discussion with the subjects.

Background: Unstable surface-based core training can significantly enhance core strength, but no studies have compared the effects of balance pad- and sling-assisted exercises. Objects: To study the effects of unstable surface-based balance pad- and sling-assisted core strength exercises on muscle activity. Methods: Twenty male students aged 20–25 years participated in this study. The effects of three types of core strength exercises, performed with a sling or balance pad, on the activities of three muscles, i.e., the right musculus obliquus externus abdominis (EO), right erector spinae (ES), and right gluteus maximus (GM), were examined. Results: 1) In the glute bridge exercise, the percentage of maximum voluntary contraction of the EO, ES, and GM were significantly different between the balance pad- and sling-assisted exercises. The relative contribution of the ES and GM activities to all muscle activity were not significantly different between the two training types, whereas that for EO showed a significant difference. 2) There was no significant difference in the percentage value of maximum voluntary contraction (%MVC) among the EO, ES, and GM during the “leg-lifting with flat support”exercise, and there were no significant difference in the relative contributions between the two training types. 3) In the “side bridge leg separation exercise”, the %MVC of the ES, EO, and GM were significantly different between the two training types. Conclusion: Sling training for core muscles was generally better than balance pad assist training. The majority of physiotherapy patients require core training. Our results could guide physiotherapists in the choice of targeted exercises for these patients.

Background: Hallux valgus (HV) is a foot deformity developed by mediolateral deviation of the first metatarsophalangeal joint. Although various foot-toe orthoses were used to correct the HV angle, verification of the effects of kinetics variables such as ground reaction force (GRF) through three-dimensional (3D) gait analysis according to the various type of orthoses for HV is insufficient. Objects: This study aimed to investigate the effect of soft and hard types of foot and toe orthoses to correct HV deformity on the GRF in individuals with HV using 3D motion analysis system during walking. Methods: Twenty-six subjects participated in the experiment. Participants had HV angle of more than 15° in both feet. Two force platforms were used to obtain 3D GRF data for both feet and a 3D motion capture system with six infrared cameras was used to measure exact stance phase point such as heel strike or toe off period. Total walk trials of each participant were 8 to 10, the walkway length was 6 m. Two-way repeated measures ANOVA was used to determine the effects of each orthosis condition on the various GRF values. Results: The late anteroposterior maximal force and a first vertical peak force of the GRF showed that the hard type orthosis condition significantly increased GRF compared to the other orthosis conditions (p < 0.05). Conclusion: There were significant effects in GRF values when wearing the hard type foot orthosis. However, the hard type foot orthosis was uncomfortable to wear during walking. Therefore, it is necessary to develop a new foot-toe orthosis that can compensate for these disadvantages.
