  • This paper focuses on the development of a fashion design educational program that will foster the talent and aesthetic consciousness of fashion design students. The goal of progressive educational methods with cutting edge technology is to elevate educational efficiency, and ultimately rear creative designers. To fulfill its objective, this paper presents a courseware program on fashion design education utilizing hyper media that include animation, photographs, pictures, sounds and characters. By the utilization of such comprehensive source of information media, a hypermedia courseware was developed for elementary education in fashion design with the following conclusions : 1. The program enables the students to customize their fashion design education. The students of fashion design education programs are able to choose and adjust their own programs to suit their requirements and intellectual level. 2. The program effectively motivates. Much like a constant sequence of various images on a screen that can provoke profound heart-felt emotions and inspire creativity, the program can stimulate and motivate the students. 3. The program provides a consistent education. To advance the overall quality of fashion design education, the problem of dissonance in educational content should be resolved and possible individual errors in delivery rectified. The present program will solve such problems, and establish coherent standards that will withstand the test of time regardless of time or place. 4. The program is cost effective. Since the present program frees the teacher from the time consuming drudgery of preparing various texts and lesson plans, have the materials delivered and handled, it reduces the time and cost previously required. 5. The program has the capability to be upgraded. The accumulated know-how of teachers and the total experience of the program can be linked with other programs for limitless expansion.

  • 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.

  • 'Smart Sensibility Mat (SSM)' was developed and manufactured for positive sensibility of newborn with fiber, digital, and sensibility technology to reflect features and advantages of kangaroo care. For tactile stimuli, the tube of the silicon material to provide a constant temperature of $32^{\circ}C$ was inserted into the mat and connected to the water-thermostat. To provide a uniform temperature throughout the mat, the fabric by the inserting conductive yarn was attached to the mat surface. After wrapping the mat with cotton pad, the polyurethane foam used as medicine in order to similar to the human skin was bonded to the surface of the mat. To provide the auditory stimuli of a level of 30dB with mother's heartbeat sounds and voice recorded in advance, the Bluetooth speaker was inserted into the mat. To investigate the effects of SSM, 10 newborns who born within two weeks were involved in this experiment. While the baby was lying on each of the general mat (GM) and SSM, the baby's physiological signals-heart rate, breathing rate, temperature- were measured and then, those were conducted t-test to examine the difference between the signals of SSM and GM. The results were as follows: heart rate (t=8.131, p<.001) and respiratory rate (t=7.227, p<.001) among the physiological signals of SSM decreased significantly than GM within the normal range. Temperature (t=1.062, p=0.292) at SSM showed a tendency to decrease than GM within the normal range. This means the tactile stimuli and the auditory stimuli providing from SSM give stable physiological responses. Thus, SSM leads to have psychological comfort and stability of newborns.

  • A 10-month-old intact male Maltese dog (body weight, 1.6 kg) presented with intermittent cough and abnormal heart sounds. The dog was diagnosed with a left-to-right patent ductus arteriosus (PDA) on the basis of the results of transthoracic echocardiography, color flow Doppler examination, and angiography. Transcatheter occlusion of the PDA was performed using the $Amplatz^{(R)}$ Canine Duct Occluder (ACDO) via the femoral artery. The device was placed under fluoroscopic guidance and successfully occluded the PDA. The continuous heart murmur disappeared immediately after the correction and no residual flow was detected. The dog was discharged the following day and regularly examined for complications and safety. This is the first report demonstrating the clinical application of ACDO for the transcatheter closure of PDA via the femoral artery in a small-breed dog in Korea.

  • To inspect how the different sensitivities in BAS(or BIS) modulate on the HRV pattern stimulated by positive or negative affective sound, we measured the electrocardiogram(ECG) of 25 students(male : 14), consisted of 4 groups depending on the BAS(or BIS) sensitivity, during listening meditation music or being exposed to noise. The power spectral density(PSD) of HRV was derived from the ECG, and the power of HRV was calculated for 3 major frequency ranges(low frequency[LF], medium frequency[MF], and high frequency[HF]). We found that the index of MF/(LF+HF), during listening music, was higher significantly in the individuals with a low BIS but high BAS than in the individuals with a low sensitivity in both BIS and BAS. Especially in the former group, there was a tendency that the index was higher during listening music than during being exposed to noise. For individuals with a high BIS, regardless of the BAS sensitivity, the difference of this index values was not significant. From these results we suggest that individuals with a low BIS but high BAS are more sensitive to positive affective stimuli than other groups, and the index of MF/(LF+HF) is applicable to evaluate positive and negative affects.

  • We have experienced 2 cases of the hunshot wound sof the chest involving cardiac injuries at department of the thoracic surgery, Capital Armed Forces General Hospital during I year from April I 1979 to Jan. 1980. In one case of two patients , he was a 22 years old man who was transported to this emergency room 4 hour 10 minutes after having gunshot wound of the left chest by helicopter. Physical examination showed small inlet in left 3rd ICS and left parasternal border, large outlet in left 8th ICS and left scapular line, no breath sound on left side and distant heart sound. chest roentgenography demonstrated marked pleural effusion in left side and mediastinum shifted to right. As soon as chest X-ray was taken, the bleeding through penetrating wound became profuse and cardiac arrest ensued. Closed chest cardiac massage was started and vigorous transfusion continued, but no effective cardiac activity could not be obtained. The patient was pronounced dead due to exsanguinating hemorrhage from wuwpected cardiac wounds. In this critically injured patient with evidence of intrathoracic hemorrhage and suspected cardiac penetration, only emergency thoracic exploration and immediate surgical control of bleeding points might offer the maximum possibility of survival. The other case was a 23 years old man who was transferred to the emergency room 4 hours 50 minutes after having kmultiple communicated fractures of sternum and linear fracture of right mandible by a missile. Examination revealed about 30% skin loss of the anterior chest wall, weak pulse of 96 beats/min., distant heart sound and decreased breath sounds bilaterally. finding on the chest X-ray films showed multiple sternal fractures, marked pericardial effusion indicating hemopericardium. So, the patient was moved immediately to the operation room where, after endotracheal tube inserted, a median sternotomy was performced. A hemorrhagic congestion of the right upper lobe and marked bulging pericardium were disclosed. The pericardium was opened anterior to right phrenic nerve and exsanguinating hemorrhage ensued from the 0.5cm lacerated wound in the auricle of right atrium. The rupture site of right atrium was occluded with non-crushing vascular clamps and then was over sewn with interrupted sutures. It was thought to be highly possible that he was alive long enough to have cardiorrhaphy because of cardiac tamponade, which prevented exsanguinating hemorrhage. He was taken closed reduction for linear fracture of right mandible 2 weeks after repair of ruptured right auricle in dental clinic. This patient's post-operative course was not eventful.

  • An 82-year-old female non-smoker with a history of hypertension presented with increasing dyspnea, cough and some purulent sputum without fever. Upon admission, the patient was in a distressed condition. Auscultation revealed diminished breath sounds with no rales over the right lung. An examination of the heart revealed a regular rhythm and a systolic murmur radiating from the apex of the heart. There was no pitting edema in the lower extremities. The blood tests showed mild leukocytosis and an increased C-reactive protein level. The $O_2$ saturation was 98 % whilst breathing room air. The electrocardiogram demonstrated sinus tachycardia. The chest radiograph showed a moderate cardiomegaly, right lobe infiltrates, and blunting of the both costophrenic sulcus suggesting a small pleural effusion. Three days after admission, the symptoms became slightly aggravated despite being treated with empirical antibiotics for presumed community-acquired pneumonia. Transthoracic color Doppler echocardiography indicated an ejection fraction of 48 %, mild left ventricular enlargement, and moderate left atrial enlargement resulting in severe mitral regurgitation. The clinical symptoms and right pulmonary edema resolved quickly with intravenous furosemide treatment.

  • Background : Wheezing is an important clue in the diagnosis of asthma. Previously, a Korean National asthma survey used a written questionnaire, containing the question, "Have you ever experienced a breathing sound-like 'sack-sack' or a flute sound (the Korean description for wheezing) during the last 12 months?" The response to this question showed a large discrepancy between the prevalence of wheezing and physician diagnosed asthma. This might have resulted partly from a misunderstanding of the question, due to an inadequate description for wheezing. This study was aimed at finding how well the layman understands the term "wheezing" when described as a breathing sound-like 'sack-sack', a whistle or a flute. Subjects and method : Sixty subjects, without experience of wheezing(group I), and 45 subjects, with chronic cough alleging wheezing(group II), were recruited from the Hallym University's Sacred Heart Hospital, in Anyang, Korea. Four different breathing sounds; vesicular, wheezing, tracheobronchial and crackle, were played for the subjects, without any experience with wheezing, and they were asked "which sound is most like that you would imagine when asked about a breathing sound-like 'sack-sack', a whistle or a flute?" This was followed by replaying the true wheezing sound, and then a global assessment was requested for the concordance between the real wheezing sound and the imagined wheezing sound. The wheezing sound was played for those subjects alleging wheezing, and they were asked, "have you really experienced that sound". Results : Only 46.7% of group I answered correctly, with 13.3% choosing the vesicular sound, 16.7% the tracheobronchial sound, 5.0% the crackle and 18.3% failed to answer. The concordance between their imagined wheezing and the real sound was $69.3{\pm}22.4%(mean{\pm}S.D.)$. 77.8% of group II recognized the correct sound as the one they had experienced. Conclusions : Language is not sufficient to the layman for describing natural sounds, such as wheezing.

  • This paper considers the acoustical characteristics of the closing click sounds of the mechanical valves employed in an implantable biventricular assist device (BYAD) and their re1evance to the Physical states of the valved. Bj rk Shiley Convexo Concave tilting disk valve was chosen for the study and acoustic measurement was made for the BYAD operated in a mock circulatory system as well as implanted in an animal (sheep). In the BYAD operated in the mock circulatory system. three different states of the valve were examined, ie. normal. mechanically damaged. pseudo-thrombus attached. Microphone measurement for the BVAD implanted in the animal was carried out for five days at a regular time interval from one day after implantation. Characteristic spectrum of the sound from the valve was estimated using Multiple Signal Classification (MUSIC) in which the optimal order was determined according to Bayesian Information Criterion (BIC) . It was observed that the mechanical damage of the valve resulted in changes of the structure of the acoustic spectrum. In contrast. the thrombus formed on the valve did not change much the basic structure of the spectrum but brought about altering the spectral Peak frequencies and energies. Maximum spectral Peak (MSP) with the greatest energy was seen at 2 kHz for the normal valve and it was shifted to 3 kHz for the calve attaching the Pseudo-thrombus. Unlike the normal valve, strong spectral Peak appeared around 7 kHz in the sound from the valve mechanically damaged. In the case of the BYAD implanted in the animal. as the thrombus grew, acoustic energy was reduced relatively more in the low frequency components (〈 2 kHz) and the frequencies of the 1st, 2nd and 3rd MSP were increased little. The thrombus formation would result in reduction in both the variability of the 1st, 2nd and 3rd MSP and the value of the BIC optimal order.

  • Hypertrophic cardiomyopathy (HCM) is the most often seen type of cardiomyopathy in cats. The cause is unknown but a genetic basis is thought to underlie some cases. Thromboembolism (TE) is a troubling complication in cats with myocardial disease. Two cats referred to Seoul National University Hospital for Animals with the paralysis of bilateral hindlimbs after vomiting. The cats were depressed and the bilateral hindlimbs were cyanotic, cool and painful. Heart murmur sounds were auscultated in both cases. Through radiographic and echocardiographic evaluation, HCM was diagnosed. TE at the distal aortic trifurcation was also visualized on abdominal ultrasonography. Both cats were expired and HCM and saddle thrombus were confirmed by postmortem examination in one cat.
