Background: The deep cervical flexor (DCF) muscles have a crucial role in the management of neck pain. For preventing neck pain by activation of the DCF, craniocervical flexion (CCF) is an effective exercise. However, sternocleidomastoid (SCM) muscle is considered to affect negatively the activation of the DCF. SCM muscle which is an accessory muscle for respiration is activated differently depending on types of breathing patterns. It's not certain that breathing patterns affect the SCM and DCF muscles thickness during CCF exercise. Objects: The purpose of this study was to investigate the influence of breathing patterns on the SCM and DCF muscles thickness during CCF exercise. Methods: Forty-five subjects participated in this study, and they were classified according to their breathing pattern, as follows: costodiaphragmatic breathing (CDB) and upper costal breathing (UCB) groups. Ultrasonographic imaging of the SCM and DCF muscles was performed during five incremental levels of CCF during tidal breathing and expiration. Results: There was a significant interaction between the breathing pattern and the phase of CCF for percentage of SCM muscle thickness changes (p<.05). In phase 1 CCF, a percentage of SCM muscle thickness changes was increased in the UCB group than in the CDB group (p<.05). There was an increase in DCF muscles thickness with each additional CCF phase (p<.05). Conclusion: Recruitment of SCM muscle was increased in the UCB group while performing CCF with a low intensity. There were no significant differences on DCF recruitment between the breathing pattern groups. Higher CCF exercise intensities elicited a higher DCF recruitment.

An 8-year-old castrated male domestic shorthair cat (Case 1) and 3-year-old castrated male Siamese cat (Case 2) was presented with acute paresis of the hindlimbs, constant open-mouth breathing, and hemoptysis. Heart murmur (Case 1) and gallop sound (Case 2) was ausculated on the left heart base. Radiographs revealed alveolar infiltration of the caudodorsal lung lobes with aerophagea in Case 1 and prominent cardiomegaly in Case 2. Marked concentric hypertrophy of the ventricular septum and free wall, and left atrial enlargement was detected through echocardiography in both cats. Based on the examinations including echocardiography, those cats were diagnosed as hypertropic cardiomyopathy. Abdominal ultrasound revealed echogenic material in the aortic trifurcation region, aortic thromboembolism (ATE). Although prognosis of those animals was guarded, interventional therapeutic approach through direct endovascular thrombolytic therapy was attempted. ATE was visualized through angiography; however dissolving the embolus using interventional thrombolytic approach was not successful due to the extensive thrombus.

In this paper want to recognize competition and cooperation as a non-contact sensing method among the social emotion that are caused by interaction. Experiments were conducted in a pattern matching task divided into competition and cooperation situations. Data collection was performed by extracting the micro-movement data of 15Hz component from the upper body image. We compared and analyzed the amount and the variation and synchronization. As a result, Amount and variation are bigger in competition than cooperation. Synchronization was higher in cooperation than competition. This can be seen as the difference between two people trying to win when they are in competition and trying to breathe each other in cooperation. This study is significant in confirming the possibility of competition and cooperation through non contact sensing method based on physiological response.

PURPOSE: This study examined the correlation between the visual analog scale (VAS) and the rate of change in the respiration patterns according to the result of Lumbar Instability Tests (LITs) in young people with chronic low back pain (CLBP) METHODS: Thirty-six adults, aged 20-40 years with CLBP, participated in this study. The general characteristics and VAS of the participants were recorded by the subjects themselves and seven structure and functional LITs were conducted. According to the positive response number, the positive group was divided into four groups (group 1: n=8, group 2: n=9, group 3: n=10, group 4: n=9). The breathing pattern change tests were performed in three states: during forced breathing exercise and motor control tests. A total of 13 positive lists were set, each of which was scored by 1 or 2 points according to the severity. After the positive lists were scored, the breathing pattern changing rate (BPCR) and VAS were compared according to the positive response number of LITs, and the correlation between them was analyzed. RESULTS: A strong correlation was observed between the number of positive of LITs and BPCR (r= .863, p= .000) and a moderate correlation between the positive number of LITs and VAS (r= .508, p= .002). In addition, there was a poor correlation between the BPCR and VAS (r= .434, p= .008). CONCLUSION: In young CLBP people, when the structural and functional instability are both present, the changes in the respiratory pattern of the whole body can be varied and broader, and the pain scale also increases.

PURPOSE: This study examined the changes in the respiratory function when PNF chopping and lifting patterns were used in chronic stroke patients METHOD: The subjects were 30 patients diagnosed with chronic stroke. The respiratory function (FVC, FEV₁, and FEV₁/FVC) were measured by spirometry. Thirty subjects were divided randomly into an experimental group to which 15 PNF chopping and lifting were applied and a control group to which chest breathing exercise was performed. The intervention was conducted three times a week for six 6 weeks. To examine the effects of intervention, the pre- and post-intervention values for each group were compared using a paired t-test. An independent t-test was used to compare the differences in the values of changes pre- and post-intervention in the two groups. Statistical significance was set to .05. RESULTS: Satistically significant differences in FVC and FEV₁ were observed in both the experimental group and control group according to the intervention (p < .05). A statistically significant difference was found in FVC and FEV₁ compared to values of changes pre- and post-intervnetion between the experimental and control groups. There was no difference in FEV₁/FVC. CONCLUSION: The results suggest that PNF chopping and lifting can be applied as an excellent respiratory intervention program compared to general chest breathing exercises to improve respiratory function in stroke patients.

This study was conducted to investigate the effects of dietary garlic and may flower powder on $CO_2$ and $CH_4$ emission by Hanwoo cows fed TMR (Total Mixed Ration) based diet. Animals were housed in a hood-type respiration chamber and the environmental temperature was maintained at $20^{\circ}C$. Gases were measured for 24 hours using the multi-detector instrument gas monitoring system (Mamos-300, Australia). The treatments composed of groups with no intake of garlic and may flower powder (Control), with intake of garlic at 0.5% of DM (T1), with intake of garlic at 1% of DM (T2), with intake of may flower at 0.5% of DM (T3), with intake of may flower at 1% of DM (T4), with intake of garlic and may flower at 0.5% of DM (T5) and with intake of garlic and may flower at 1% of DM (T6). The results indicated that $CO_2$ emission in T3 was 53% lower than that of control (p<0.05), and $CH_4$ emissions was 57% lower than control (p<0.05). Also, the hourly pattern of $CO_2$ and $CH_4$ emissions in T3 showed the least difference with all treatments. Gas emissions pattern peaked after 1 hour of feeding and this gap was wider in the afternoon than in the morning hours.

In order to develop a Patient respiratory management system includinga biofeedback function for4-dimentional radiation therapy, this study investigated anoptimal tracking algorithmfor moving target using IR (Infra-red) camera as well as commercial camera. A tracking system was developed by LabVIEW 2010. Motion phantom images were acquired using a camera (IR or commercial). After image process were conducted to convert acquired image to binary image by applying a threshold values, several edge enhance methods such as Sobel, Prewitt, Differentiation, Sigma, Gradient, Roberts, were applied. The targetpattern was defined in the images, and acquired image from a moving targetwas tracked by matching pre-defined tracking pattern. During the matching of imagee, thecoordinateof tracking point was recorded. In order to assess the performance of tracking algorithm, the value of score which represents theaccuracy of pattern matching was defined. To compare the algorithm objectively, we repeat experiments 3 times for 5 minuts for each algorithm. Average valueand standard deviations (SD) of score were automatically calculatedsaved as ASCII format. Score of threshold only was 706, and standard deviation was 84. The value of average and SD for other algorithms which combined edge detection method and thresholdwere 794, 64 in Sobel, 770, 101 in Differentiation, 754, 85 in Gradient, 763, 75 in Prewitt, 777, 93 in Roberts, and 822, 62 in Sigma, respectively. According to score analysis, the most efficient tracking algorithm is the Sigma method. Therefore, 4-dimentional radiation threapy is expected tobemore efficient if threshold and Sigma edge detection method are used together in target tracking.

Purpose: Respiratory syncytial virus (RSV) and human rhinovirus (hRV) are the most common causes of child respiratory viral infections. We aimed to investigate epidemiological and clinical characteristics of RSV and hRV single infections and coinfections. Methods: Nasopharyngeal aspirates of hospitalized children aged <5 years were tested using multiplex reverse transcription polymerase chain reaction (RT-PCR) from October 2014 to April 2017. Their medical records were retrospectively reviewed. Results: RSV or hRV was detected in 384 patients who divided into 3 groups: patients with RSV (R group, n=258); patients with hRV (H group, n=99); and patients with both (RH group, n=27). The R group (median age, 6 months) consisted of 248 (96.1%) patients with lower respiratory tract infection (LRTI), and 14 (5.4%) needed oxygen inhalation. Infants aged <12 months (63.2%) had respiratory difficulty and were supplied oxygen more often. The H group (median age, 16 months) consisted of 56 (56.6%) patients with LRTI, 4 (4%) required oxygen inhalation, and 1 (1.0%) required mechanical ventilation. Infants (40.4%) showed longer hospitalization compared to patients aged ${\geq}12$ months (5 vs. 4 days, P<0.05). The RH group consisted of 24 (88.9%) patients with LRTI, and 2 (7.4%) needed oxygen inhalation. Hospitalization days and oxygen inhalation and mechanical ventilation rates did not differ between single infections (R and H groups) and coinfections (RH group). Conclusions: RSV was detected more often in younger patients and showed higher LRTI rates compared to hRV. Single infections and coinfections of RSV and hRV showed no difference in severity.

The purpose of this study is to investigate the quality changes and contamination of microorganisms such as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) in cherry tomatoes and head lettuces during the storage of different temperatures and periods. This study determines the pH levels, color changes and the growth patterns of microorganisms in cherry tomatoes and head lettuces during storage of 14 days at $5^{\circ}C$, $10^{\circ}C$ and $15^{\circ}C$. According to the results, the pH level is being reduced with storage periods in cherry tomatoes and head lettuces. The $L^*$, $a^*$ and $b^*$ values of cherry tomatoes are decreased with storage period, whereas the $a^*$ and $b^*$ values have increased with storage of the head lettuces. With regards to the types of microorganisms, the aerobic count plate (ACP), coliform count (CC), mold and yeast are being detected when cherry tomatoes and head lettuces are stored at $5^{\circ}C$, $10^{\circ}C$ and $15^{\circ}C$, whereas the S. aureus and E. coli are not being detected at 14 days of storage. The ACP, CC and yeast of cherry tomatoes increase with storage period, whereas the mold of cherry tomatoes was decreased after 14 days of storage. For the head lettuces, APC and CC have significantly increased with storage, whereas the mold stored at $5^{\circ}C$, $10^{\circ}C$ and $15^{\circ}C$ decreased after 21 days of storage. From these studies, we can confirm that changes in quality characteristics and the types of microorganisms existed in cherry tomatoes and head lettuces during storage were the ACP, CC, mold and yeast, whereas the E. coli and S. aureus are not detected.
