A behavioral investigation in deer equipped with EMG telemetry system was carried out to examine the chewing behavior pattern for efficient feeding management of Korean spotted deer(Cervus nippon). There was more frequent and irregular eating and rumination behavior pattern in deer than those in other ruminants. Time spent on eating and ruminating was 261 and 291 min., respectively. Total number of boli regurgitated was 647 times per a day and deer regurgitated an average boil of 21.6 times per a rumination period. Total rumination time was 291 min. and deer have an average rumination time of 26.9 sec. per a boli. Deer had 245.3 min. for total chewing time, 20,405 times fur number of chews, 31.5 times for number of chews per bolus, and 53.4 times for number of chews per minute during rumination period. An average regurgitation bolus an hour was lower with 15.3 numbers in the 09∼15 hours subperiod and higher with 26 numbers in the 15∼21 hours subperiod and it had been gradually trended to become to low after 15∼21 hours subperiod. An average numbers of chews a bolus at every 6 hours subperiod increased gradually according to time. A deer spent 23.3 min. on eating and 26.2 min. on ruminating per 100g ingested dry matter. Consequently, since deer have a different chewing behavioral pattern to other ruminants such as more frequent and irregular eating and ruminating patterns, small bolus and low number of chew, it is likely to needed to establishment and development efficient feeding system for deer.

If complication arises after glossectomy which leads to trouble in forming food bolus or transfer of the food, it is possible that either food bolus may block the airway or dysphagia may occur as the food bolus goes down into the airway. To solve the issue, palatal augmentation prosthesis could be used. In this case, the patient with an oral cancer is having difficulties swallowing food after glossectomy. Through taking impressions of polishing surface of his denture referring his tongue movement, the complete denture for the upper jaw was created using the concept of palatal augmentation prosthesis. This new upper denture increases the palatal-tongue contact pressure, allowing the patient to perform better swallowing and better pronunciation.

The purpose of this report is to describe the diagnosed case of a large colonic impaction in an adult donkey. An adult female donkey (Equus africanus asinus; 6-years-old) was admitted to the Equine Hospital of Jeju Race Park with signs of anorexia, which had started 1 day previously. Clinical examination revealed: weak gut sounds, dehydration, and severe abdominal distension, but normal respiratory and heart rates and no signs of pain. Transrectal palpation identified an impaction in the colon. The patient was treated with nasogastric siphonage, fluid therapy, and nonsteroidal anti-inflammatory drugs. Over the course of a day, her condition worsened; she started trembling, could not stand, and 2 hours later she died. Upon necropsy, a vast amount of ingesta was found in the large colon, particularly in the left ventral colon. The cecum and small colon were normal. Eleven days prior to presentation, the stable management and diet of the donkey had changed. We suspect that the change of feed, reduced water consumption, and lack of exercise precipitated the illness. However, the exact cause of the sudden death of the donkey requires further investigation.

This study was carried out to investigate the effects of by-product mixing silage feeding on the eating and ruminating behavior of fattening Hanwoo steer. A total of 12 Hanwoo steers (21 months old) were divided into three feeding groups and assigned to 3 dietary treatments: control (C: concentrate + ad libitum feeding of rice straw), and by-product mixing silage groups (T1: concentrate + 1 kg restricted feeding of by-product mixing silage + ad libitum feeding of rice straw, T2: concentrate + ad libitum feeding of by-product mixing silage). Eating behaviors were observed for 48 hours. Total feed intake was high in the order of T1 > C > T2, but not significantly different among the treatments. The eating and chewing time were significantly higher in C than by-product mixing silage treatments (P<0.05). Ruminating and resting time were not significantly different among the treatments. Number of bolus, number of total chews and number of chews per bolus were not significantly different among the treatments. But ruminating time per bolus and FVI (feed value index) were significantly higher in C than T1 and T2 (p<0,01, 0.05). Bolus per minute was the highest in T1 (p<0.01). Number of drinking was significantly higher in T2 than C and T1 (p<0.05), but defecating and urinating were not significantly difference among the treatments. Eating rate was the highest in T2 (p<0.05), but ruminating and chewing efficiency were not significantly difference among the treatments. Consequently, there was no big difference on eating behavior when feed by-product silage comparing with rice straw. Therefore, it is thought that by-product mixing silage could be the alternative for the rice straw.

Effects of low quality roughage sources on duration and frequencies of rumination and chewing in Hanwoo steers were determined, Animals were fed three diets; concentrate+rice straw(SO:SO), concentrate+ rice straw + popped rice hull(SO:3S: IS) and concentrate+ rice straw+ground rice hull(SO:3S: IS) to compare both rice straw alone and combination with rice hull. Eating and ruminating time of steers fed concentrate+ rice straw(SO:50), concentrate+ rice straw + popped rice hull(50:35:15) and concentrate + rice straw + ground rice hull(50:3S:15) were 78.8 and 338.4minlday; 98.0 and 362.5minlday, and 160 and 519.2min/day, respectively. When steers were fed popped rice hull and ground rice hull, time spent for both eating and ruminating was significantly increased(p <0.05). When steers fed popped and ground rice hull, number of ruminating chews and number of chews per rumination time were significantly decreased(p<0.05). The number of rumination boli and boli per rumination time had significantly decreased(p<0.05), but chewing time per boli, number of chew'S per bolus were significantly increased(p

This study was performed to examine the presence of dysphagia and analyze characteristics of the symptoms in cerebrovascular accident(CVA) patients without awareness of dysphagia. A questionnaire for this study was given to CVA patients who had visited P rehabilitation medical center in Busan. Eleven patients (4 males and 7 females) who answered no awareness of dysphasia were given to VFSS, functional dysphasia scale, and NCSE. Descriptive statistics and Pearson correlation analysis were performed by SPSS 12.0. All of subjects without awareness of dysphasia showed characteristics of dysphasia symptoms. Prominent dysfunctions were problems in oral phase and delay of swallowing reflex in pharyngeal phase. For the aspect of cognition, they showed lower score in construction, memory, and similarity than other NCSE items. There was highly significant correlation between orientation, judgment and delay of swallowing reflex. Verbal comprehension and residual materials in oral cavity showed closed correlation. CVA patients without awareness had dysphagia with high probability. The early evaluation of dysphagia should be performed in CVA patients in order to prevent complications due to CVA, so it is necessary to increase the effectiveness of rehabilitation therapy.

This study was carried out to investigate the effects of a different growing stage on the eating and ruminating behavior of Holstein steer (Bos taurus). A total of nine Holstein steers were divided into three growing stage groups (T1: growth stage, 8 months old, T2: Early fattening stage, 15 months old, T3: late fattening stage, 24 months old) with 3 replicates. In the feeding method, concentrate was offered at 1.62% of the body weight per treatment, respectively. And the forage was fed ad libitum for all treatment. The results of behaviors are summarized as follows: The rate of dry matter intake compared to body weight (DMI/BW, %) was high in the order of T1(2.21%) > T2(2.09%) > T3(1.39%). Eating time, ruminating time and resting time were significantly higher in T1, T2 and T3, respectively(p<0.05, 0.01). Chewing time was significantly lower in T3 than in T1 and T2(p<0.01). The number of bolus and the number of total chews were significantly higher in T2 than those of the other treatments(p<0.01). However ruminating time per bolus and the number of bolus per minute were not significantly different among the treatments. The numbers of drinking and defecating were not significantly different among the treatments. The number of urinating was significantly higher T1 than those of the other treatments(p<0.01). Time of drinking, defecating and urinating was not significantly difference among the treatments.

Occlusal appliance therapy has been proven to be very useful and effective in reducing signs and symptoms of patients with TMD. However, there are no reports about the masticatory efficiency of the occlusal appliance. The purpose of this study was, first, to investigate the masticatory efficiency of the conventional stabilization appliance experimentally in normal healthy subjects, by comparing it with that of their natural dentition; and, second, to develop a modified stabilization appliance as an attempt to increase masticatory efficiency. Eleven subjects (mean age 25.3 years, range from 23 to 33) participated in this study. Six were men and five were women. They were healthy and had complete or near―complete natural dentition, and did not present with signs or symptoms of TMD. Two kinds of occlusal appliances―the conventional flat maxillary stabilization appliance (i.e., FSA) and a modified maxillary stabilization appliance with additional anatomic structures on its occlusal surface (i.e., ASA)―were made for every subject. Subjects chewed peanuts that were selected as a food to test the three masticatory conditions of the natural dentition, the ASA, and the FSA. The number of chewing strokes was counted during each 1-minute chewing period. Chewed peanut boluses were recovered and their hardness was measured by texture analysis. Statistical tests were performed. The following results were obtained. 1. The masticatory efficiency of the FSA was 38.6 percent that of the natural dentition. The efficiency of the ASA was 78.2 percent that of the natural dentition. 2. The number of chewing strokes in the natural dentition condition was measured to be 1.5 strokes per second. It decreased to 90 percent in the ASA and FSA conditions. These results indicate that the ASA could serve an improved masticatory capacity as well as its therapeutic effects in TMD. A clinical application of the ASA should be considered to extend the management of TMD patients.

This study was carried out to investigate the effects of stocking density on the eating and ruminating behavior of growing Hanwoo steer (Bos taurus coreanae). A total of thirty growing Hanwoo steers were divided into four stocking density groups (G1: 1 head/32 $m^2$, G2: 2 heads/32 $m^2$, G3: 3 heads /32 $m^2$, G4: 4 heads/32 $m^2$) with 3 replicates (12 pens). The results of eating behaviors for 48 hours are summarized as follows: Total intake was higher in 2G, 3G and 4G than in 1G, but not significantly different among thetreatments. Intake of roughage was the highest in 2G (3.32 kg), while 1G (2.85 kg) was the lowest (P<0.05). Eating time of concentrate was highly in the order of 1G > 2G > 3G > 4G (P<0.05). But eating time (concentrate + roughage) and ruminating time were not significantly difference among the treatments. Resting time (standing + lying) was the highest in 4G (P<0.01), and lying time was the highest in 2G. Chewing time (Eating + ruminating) was higher in 3G than in 1G, 2G, and 4G (P<0.05). Number of bolus, number of total chews, ruminating time per bolus and number of bolus per minute were not significantly difference among the treatments. But number of chews per bolus was significantly lower in 1G than those of the other treatments (p<(0.05). Number of urinating was in the order of 1G > 4G > 2G > 3G (P<0.05). However, stocking density had no effect on drinking and defecating. Eating rate and chewing efficiency were the highest in 4G (P<0.01, 0.05), but ruminating efficiency was not significantly difference among the treatments.

Foreing bodies of the esophagus and tracheobronchus are likely to occur whenever a child places an inedible object in the mouth and are common in the older age group particularily in edentulous individuals or preexisting disease. Our department had already reported the statistical survey at first in 1954, successively in 1962, 1963 and 1968, respectively according to the age, sex, variety of foreign bodies, location and duration of the lodgement. Now, we have experienced the new 186 cases during the consecutive 5 year period from January 1973 to December 1977 and reported as a 5th report comparing with previous report. The results were as follows. 1. In the incidence of foreign bodies, coins were the most common and pointed metal, disc, bony fragment were followed in order in the esophagus while the peanut and corn were common in the air passage. 2) 79 cases (56.4%) were males and 61 cases (43.6%) were females in the esophagus, which was not a significant difference to note. But in the air passage, males accounted for 33 cases (71.7%) compared to 13 cases (28.3%) of females. 3) In the aspect of age incidence, child 10 years or under accounted for almost all cases in the esophagus as well as in the air passage. 4) In the location of foreign bodies in the esophagus, the first narrowing was the most common, while in the air passage right bronchus had a high incidence but the difference of incidence between right bronchus and left bronchus was not remarkable. 5) The duration of lodgement was 24 hours or less in more than half of the all cases. 6) In the aspect of kind of coin, 10 won coins accounted for majority of the cases (67.0%) but the incidence of 100 won coins were tend to increase gradually in these years.
