  • These studies were performed to establish more effective surgical method for correcting congenital atresia coli in calves. Distal colon fistulation, proximal colon fistulation and colon anastomosis which could be applied for surgical repair of intestinal obstruction were carried out in goatlings experimentally and in calves with atresia coli clinically. After treatment of the animals clinical signs, blood component values, body weight gain, survival and necropsy findings were observed. In goatlings, clinical signs after colon fistulation were diarrhea, anorexia and vitality loss, and those of proximal colon fistulation group were severer than those of distal colon fistulation group. Surviviability after operation was 9~16 weeks in distal colon fistulation group, 2~8 weeks in proximal colon fistulation group, and 2-3 days in colocolic anastomosis group, respectively. There were no alterations in blood component values among experimental groups. Weight gain rates were 54.6% in distal colon fistulation group and 42.9% in proximal colon fistulation group compared with those of control. Necropsy findings observed in experimental groups were distension of intestine and excessive fluid in abomasum and intestine. Two calves with atresia coli died 1 day and 6 days after operation but one with colon fistulation survived more than two months. Preoperative clinical signs in calves with atresia coli were abdominal distension, progressive anorexia, no defecation and postoperative clinical signs wert diarrhea and periodic abdominal distension. After operation there were no alterations in blood component values between the calf with atresia coli and control calf. Weight gain rate of calf with atresia coli was similar to that of control but revealed the tendency to decrease from the 2nd month after operation. Necropsy findings observed in two calves with atresia coli were intestinal distension. intraluminal excessive fluid, blind atretic sac and absence of intrarectal content. It was concluded that proximal or distal colon fistulation could be available for surgical correction of congenital atresla coli and prognosis of distal colon fistulation was better than of proximal colon fistulation, but that extensive colocolic anastomosis could not be compatible with life in ruminants.

  • Objectives: The present study evaluated the effects of sa-am acupuncture (SAA) simpo-jeongkyeok (SPJK) treatment on the blood pressure (BP), pulse rate (PR), and body temperature (BT) of patients with hwa byung (HB). Methods: This patient assessor blind, randomized, placebo controlled trial included 50 volunteers, divided randomly into two groups. The treatment group underwent SPJK (PC9, LR1, PC3, KI10) while the control (sham) group received minimal needle insertion at non acupoints. The BP in both arms, PR, and BT at several acupoints were measured before and after treatment at the $1^{st}$, $2^{nd}$, $3^{rd}$, and $4^{th}$ visits and before treatment at the follow-up visit. We analyzed data by using the repeated measured analysis of variance (RM ANOVA), Mann-Whitney U, and wilcoxon signed rank tests; differences at P < 0.05 were considered significant. Results: No significant differences in the systolic blood pressure (SBP), diastolic blood pressure (DBP) and PR between the treatment and control group were observed at each visit. However, the decrease in the SBP for the treatment group before and after each visit was significantly higher than it was in the control group. The SBP in both arms in the treatment group was decreased between visits 1 and 2, 1 and 3, 1 and 4, and 1 and follow-up. The DBP in both arms and in the right arm between visits 1 and 3 in the treatment group showed decreases. A minimal BT increase for treatment at CV06 and CV12 and a minimal BT decrease for treatment at CV17 and (Ex) Yintang were found. Patients in the treatment group who visited more frequently experienced a greater decrease in the PR, but that effect was not maintained. Conclusion: The results suggest that SAA SPJK treatment has instant positive effects on the BP, PR, and BT in patients with HB, but the effects on the BP and PR are not maintained.

  • Purpose: The purpose of this paper is to determine effects of auricular acupressure on knee pain, range of motion, and sleep in the elderly with knee osteoarthritis. Methods: This is an experimental study designed with randomization and single-blind in a placebo-control approach. The subjects included the elderly with knee osteoarthritis who were using an elderly welfare facility. In each of the groups, 28 subjects were assigned. For the experimental group, auricular acupressure was applied to five pressure points related to the pain caused by osteoarthritis and sleep. In the case of the placebo-control group, auricular acupressure was applied to other five points than the former. The intervention lasted eight weeks. In order to examine intervention effects of auricular acupressure, joint pain, Pressure Pain Thresholds (PPTs), and extension and flexion range of motion (ROM) were measured weekly. As for the preand post-examinations, pain, sleep quality, and the time-by-sleep stage of the patients with knee osteoarthritis were measured. Results: The VAS scores in the experimental group with auricular acupressure significantly decreased through time (p<.001) and WOMAC also significantly decreased (p<.01) compared with the placebo-control group. However, there were no significant differences in PPTs. The flexion (p<.01) and extension (p<.001) ROMs measured for eight weeks improved over time. Meanwhile, sleep quality improved significantly after the intervention termination (p<.01), but there was no significant difference found in the time-by-sleep stage. Conclusion: Auricular acupressure applied for eight weeks was found to be effective in reducing joint pain, improving knee ROM, and improving sleep quality in patients with degenerative knee arthritis.

  • Background: The aim of this study was to compare the local anesthetic effect of tramadol with that of lignocaine in the extraction of immobile (grade 0) maxillary first molars. Methods: This was a randomized, double-blind, equally balanced, controlled trial conducted on a sample population of 116 patients. The patients were randomly divided into two groups: group A (control) and group B (study). Group A and group B participants received 1.8 ml of 2% lignocaine without adrenaline and 1.8 ml of 5% tramadol, respectively through the supra-periosteal infiltration technique before extraction. Intraoperative pain was recorded on the Visual Analog Scale (VAS) and was evaluated using two unpaired t-tests. Results: Intraoperative pain was evaluated in both the control and study groups. In the control group, the mean VAS score was 0.71 ± 0.81, while in the study group, the mean intraoperative VAS score was 1.21 ± 0.86, with the difference between the two mean values being statistically significant (P = 0.001). Conclusion: Tramadol has a less potent local anesthetic effect than lignocaine. As a higher dose of tramadol is required to obtain the desired anesthetic effect, it should be used as a supplement to lignocaine in extensive surgical procedures. It can also be used in patients allergic to lignocaine.

  • Purpose: To investigate the effect of action observation training on the muscle onset time and symmetrical use of rectus femoris(RF) and gastrocnemius medialis(GCM) during sit-to-stand (STS). Methods: Sixteen patients with stroke entered a single-blind trial and were randomly assigned to the experimental(Action) or control(Landscape) groups. Those in the Action observation group watched video clips showing specific movement and strategies to STS, wheas those in the control group watched video clips of static pictures showing differnet landscapes. All patients was measured the EMG data in the STS on the affected side and unaffected side. The EMG data were collected from RF and GCM while performing the STS task. The EMG onset time and onset time ratio for the RF and GCM were calculated by dividing the EMG onset time of RF and GCM action on the affected side by these on the unaffected side. Results: Onset time of affected side RF, GCM was significantly faster action observation training group than control group(p<.05). But interventions before and after the symmetry did not show a significant increase. Conclusion: There findings suggest that action observation training has a positive effect on the muscle onset time shortened during STS tasks.

  • A pan-tilt-zoom (PTZ) camera-based monitoring system for efficient monitoring in the engine room of a vessel was designed. A number of places exist where traditional analog instruments are still used in vessel engine rooms, and blind spots closely related to safety exist, for which flooding or fire is a concern. A camera-based monitoring system that guarantees a wide range at a relatively fast cycle for these monitoring points can be an effective alternative to enhance the safety of a vessel. Therefore, a multiview monitoring system is proposed in which the functions of the existing PTZ camera are further strengthened using a software. The monitoring system comprises four modules: camera control, location registration, traversal control, and multiview image reconstruction. The effectiveness of the method was evaluated through a series of experiments in an engine room environment.

  • Background: Achieving successful pain control and adequate anesthesia through an inferior alveolar nerve block for endodontic treatment in cases with symptomatic irreversible pulpitis (SIP) is difficult, especially in mandibular molars. This study was designed to compare the effect of oral medication with ibuprofen and soft laser therapy on inferior alveolar nerve block during endodontic treatment. Methods: The trial comprised 180 patients (45 each group) with SIP. Four groups of patients were created: group 1 received 400 mg of ibuprofen; group 2 received soft laser irradiation; group 3 received a combination of soft laser and ibuprofen 400 mg; and group 4 received a placebo 1 h prior to local anesthesia. Patients recorded their pain scores on the Heft-Parker visual analog scale (VAS) before the start of intervention, 15 min after anesthesia, during access cavity preparation, and ultimately during root canal instrumentation. Each patient also rated their level of discomfort on a VAS. Every stage with no or minimal discomfort was deemed successful. The chi-square, Kruskal-Wallis, and one-way analysis of variance tests were used to evaluate the data. Results: The best success rate was achieved for soft laser ibuprofen combination, ibuprofen and soft laser groups reported similar success results, and control group recorded the least pain scores. The mean pain scores were lowest for group 3 and highest for group 4 (P < 0.001). Ibuprofen and soft laser combination was significantly better than control group (P < 0.001). There was no significant difference between ibuprofen and laser groups (P = 0.24). Conclusions: For teeth with irreversible pulpitis, preoperative ibuprofen treatment combined with soft laser irradiation greatly improved the success rates of inferior alveolar nerve block anesthesia.

  • We studied on pesticide residue and pest control effect when using various types of sprayers on paprika cultivation. Additionally, a test was conducted to optimize chemical content per unit area in condition of optimum pest control. Two types of sprayer were tested (three times) on paprika cultivation which was divided into seven sections. Blind spots were also examined using a water sensitive paper when spraying chemical pesticide, remote controlled sprayer were confirmed to be not effective in terms of its spraying capacity. However, a U-shaped sprayer was confirmed that it sprayed enough on all the parts of a plant in green house including the blind spots. Additionally, it does not exceed the minimum residue limits on the all parts of pesticides residue conditions. When using remote controlled sprayer, water sensitive paper were changed to blue color (82.5% and 81.2%) in terms of controlling Bemisia tabaci and Aphis gossypii based on the two spraying manners. 53.0% and 42.6% of control effect were shown on the fair parts of the plants. However, on the poor parts on which pesticides were not well-sprayed, thus, not-remained, more number of pests increased. Meanwhile, on farming that only one type of pesticide has been used, resistance pests present with very low control effect, even though sufficient amount of pesticide was well-sprayed. On the test of the optimum amount of spraying per a unit area, which shows no differences in the two cases of using 5L and 2.5L of chemical pesticides on 9 plants of paprika that has 81.8% and 84.5% control effect, respectively.

  • A randomized double-blind placebo-controlled study was conducted on 63 subjects to determine the antihypertensive effect of a vegetable drink in which sardine protein hydrolysates containing a dipeptide, Valyl-Tyrosine (VY), were incorporated. The subjects, consisting of people with mild hypertension, high-normal blood pressure and normal blood pressure, were randomly divided into test (male/female=25.6, average age 50.1${\pm}$10.4 years old) and control groups (26/6, 49.0${\pm}$5.0). Each subjects in the test group was given 195g of the vegetable drink containing 0.5g of sardine peptides (sardine protein hydrolysates) with 0.4 mg of VY (test drink) once a day for 13 weeks in a row, and subjects in the control group were given the same amount of the vegetable drink without sardine peptides (control drink) in the same manner. In the test group, 40 subjects with mild hypertension of high-normal blood pressure (130 mmHg${\leq}$systolic blood pressure (SBP)<160 mmHg and/or 80 mmHg${\leq}$diastolic blood the start of the test to 134.4${\pm}$11.1 mmHg during the first week of the test period, after which similar values were seen throughout the test period (13 weeks). Compared to the control group, the difference in SBP from vaseline was statistically significant in the test group throughout the intake period. DBP also decreased significantly from 88.0${\pm}$7.9 mmHg at baseline to 83.5${\pm}$8.6 mmHg after 13 weeks. In the control group, SBP and DBP were 140.8${\pm}$8.4 mmHg and 90.5${\pm}$6.6 mmHg respectively at the start of the test, and neither decreased during the test period. In subjects with normal blood pressure, neither those in the test group nor those in the control group showed a significant change in SBP and DBP during the test period. An excessive ingestion test was performed on 25 subjects with hypertension, mild hypertension, high-normal blood pressure, and normal blood pressure by giving 585g (3 times the recommended amount of intake) of the test drink for 14 days in a row. As a result, a significant decrease of blood pressure was observed in the hypertension, mild hypertension and high-normal blood pressure groups, but no excessive decline in blood pressure or any side-effects were associated with any subjects during the test period. In the groups with normal blood pressure, the excessive ingestion of the test drink did not affect blood pressure. In these two studies, physical check-ups and biochemical analyses of blood and urine were also conducted in all subjects, and no abnormalities were observed. These results suggest that the test drink containing sardine protein hydrolysates exhibited the antihypertensive effect in only the subjects with mild hypertension or high-normal blood pressure. No adverse effects were observed in either hypertensive of normotensive subjects.
