  • Objective: The aim of the study was to evaluate the efficiency of the Hankins and Howe (HH46), Valadares Filho (V06), and Marcondes (M12) equations for predicting the physical and chemical composition of dairy crossbred bulls carcasses, as well as the chemical composition of their empty bodies. Methods: This study was conducted using 30 dairy crossbred bulls. One group of five animals was slaughtered at the beginning of the experiment, and the remaining were slaughtered 112 days later. Animals were distributed in a completely randomized design into treatments consisting different levels of concentrate (0%, 17%, 34%, 51%, and 68%). The physical and chemical compositions of the cattle were obtained from the right half of the carcass and using samples taken between the 9th and 11th ribs of the left half of the carcass. The estimated and experimentally determined values were compared using the correlation and concordance coefficient, as well as the mean square error of prediction (MSEP) and its components. Results: The HH46 equations were better at estimating the amount of muscle plus fat in the carcass. The amount of bone in the carcasses could not be well estimated by the HH46 and M12 models. The M12, HH46, and V06 equations were worst at estimating the amounts of protein, ether extract, and water in the carcass, respectively. In the empty body, the amounts of protein and water were well estimated by the HH46 equations. Protein, ether extract, and water were accurately estimated by the V06 equations, and ether extract by the M12 equations. Conclusion: The physical and chemical composition of dairy crossbred bull carcasses, as well as the chemical composition of their empty bodies, can be predicted using the equations tested here. The amount of bone in these carcasses could not be accurately predicted.

  • This study was conducted to evaluate the effects of extruded pellet (EP) diets, as compared to a raw fish moist pellet (MP) diet for olive flounder, Paralichthys olivaceus, grown in commercial-scale aquaculture for 1 year. Four diets with duplication per diet were formulated for this experiment: two experimental EP diets (EP1 and EP2), one commercial EP diet (CEP), and a raw fish MP diet (MP). The MP diet consisted of 80% frozen horse mackerel and 20% commercial binder meal. Fish weighing $30.1{\pm}0.1 g$ ($mean{\pm}SD$) were distributed randomly to each aquarium as a group of 2,600 fish. Weight gain (WG) and feed efficiency ratio (FER) of fish fed EP2 and MP were higher (P<0.05) than those of fish fed CEP, while those of fish fed EP1 did not differ (P>0.05) from those fed EP2 and MP. However, fish fed the MP diet had a higher survival rate than fish fed the other diets. Fish fed EP2 had higher serum, phospholipids and total protein levels, and lower levels of serum glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), and total cholesterol than fish fed MP (P<0.05). Dorsal muscle and liver proteins and lipid of fish fed EP1 were higher (P<0.05) than those of fish fed CEP, while those of fish fed EP1 and MP did not differ from those of fish fed EP2 (P>0.05). These results strongly suggest that EP1 could be developed to replace MP for grow-out stage production of olive flounder without adverse effects on growth performance.

  • The present study was undertaken to investigate the effects of weekly administration of implant type recombinant porcine somatotropin (rpST) on the performance and carcass characteristics in finishing pigs. A total of 120 crossbred (Landrace${\times}$Yorkshire${\times}$Duroc) pigs were employed for 11 weeks in a growth trial in experiment. A rpST designed to implant every 7 d was used. Forty pigs, each weighing 75 kg, were allocated into three rpST treatments; control (CONT), implant of rpST from 75 kg (TRT1) or 90 kg (TRT2) of body weight. The CONT pig and pigs in TRT2 from 75 kg to 90 kg were treated without rpST but with placebo. In rpST-treated pigs, each 100 mg and 125 mg of the equivalent rpST was implanted from live weight of 75 kg to 90 kg and from 90 kg to market weight, respectively. Half of the pigs from each treatment were marketed at live weight of 110 kg and the rest at 130 kg. All pigs were allowed ad libitum access to a commercial feed containing 0.94% and 0.88% of lysine from 75 to 110 kg, 110 to 130 kg of body weights, respectively. rpST had no effect on daily gain, while feed efficiency was improved by 7 to 13% (p<0.05) in the rpST-treated groups compared with the CONT. Compared with the CONT, backfat thickness was decreased by 12% (p<0.05) in TRT1 at 110 kg of market weight, and by 23 to 32% (p<0.05) in the rpST-treated groups at 130 kg of market weight, respectively. Lean muscle rate tended to be higher in TRT1 at both 110 kg and 130 kg of market weight, and carcass fat percentage in the rpST-treated groups was decreased by 33 to 46% (p<0.05) compared with the CONT.

  • This study surveys the improvement characteristics in old-aged muscular mitochondria by bio-active materials coated fabric (BMCF). To observe the effects, the fabric (10 and 30%) was worn to old-aged rat then the oxygen consumption efficiency and copy numbers of mitochondria, and mRNA expression of apoptosis- and mitophagy-related genes were verified. By wearing the BMCF, the oxidative respiration significantly increased when using the 30% materials coated fabric. The mitochondrial DNA copy number significantly decreased and subsequently recovered in a dose-dependent manner. The respiratory control ratio to mitochondrial DNA copy number showed a dose-dependent increment. As times passed, Bax, caspase 9, PGC-$1{\alpha}$ and ${\beta}$-actin increased, and Bcl-2 decreased in a dose-dependent manner. However, the BMCF can be seen to have had no effect on Fas receptor. PINK1 expression did not change considerably and was inclined to decrease in control group, but the expression was down-regulated then subsequently increased with the use of the BMCF in a dose-dependent manner. Caspase 3 increased and subsequently decreased in a dose-dependent manner. These results suggest that the BMCF invigorates mitophagy and improves mitochondrial oxidative respiration in skeletal muscle, and in early stage of apoptosis induced by the BMCF is not related to extrinsic death-receptor mediated but mitochondria-mediated signaling pathway.

  • 통영을 중심으로 한 우럭생산량은 연간 1,813M/T에 이르고 있으며, 과잉생산에 대한 우려가 제기되고 있다. 이와 같은 우려를 개선시키고 기능성 어류에 대한 소비자의 기대감을 충족시키기 위하언 성장촉진, 항암, 면역증강, 혈중 LDL 함량 저하효과를 가진 것으로 알려져 있는 CLA를 이용한 기능성 우럭생산의 가능성을 검토하였다. Artemia 영양강화시 CLA를 $0.5\~5.0\%$ 첨가하였을 경우 Artemia중 지방산조성의 변화를 조사한 결과 CLA 첨가량이 증가할수록 CLA 함량은 높아졌고, 동시에 Artemia 특유의 지방산조성을 나타내어 지방산 대사에 특별한 영향을 미치지지는 않는 것으로 나타났다. 8주 사육 후 우럭근육 중 n-6지방산의 함량이 높아 사료에 첨가된 지질의 영향을 받은 것으로 나타났다. 그리고 n-3/n-6 PUFA 비가 자연산 우럭의 3.95보다 현저히 낮아 CLA 첨가가 많을수록 성장을 저해하는 것으로 나타나 배합사료 중의 DHA 첨가가 증가되어야 할 것으로 여겨진다. 그러나 이를 섭취한 우럭 근육 중 총 CLA 함량은 급이 량에 따라 각각 $6.57\~16.07\%$가 축적되어 CLA는 다른 지질성분과 함께 어체내 대사과정을 거치는 것으로 나타났다. 우럭의 성장도, 사료효율, DHA/EPA 비, n-3/n-6 PUFA 비, 활력테스트, 혈액지수 둥을 비교하였을 때 $1.0\%$ CLA 첨가가 적절한 첨가량인 것으로 생각된다.

  • 요실금은 자신의 의지와는 무관하게 소변이 나오는 배뇨이상으로 삶의 질을 떨어뜨리는 대표적인 여성 질환이다. 치료방법 중 자기장을 이용한 치료는 자발적인 운동을 요구하지 않고, 수치심을 유발하지 않으며, 감염의 위험이 없기 때문에 가장 높은 발전 가능성을 가지고 있다. 하지만 획일화된 치료 프로토콜, 환자 의존적 치료방법, 환자 상태 평가 부재 등의 개선점도 갖고 있다. 이에 본 연구에서는 자기장을 이용하여 골반저근을 자극하고, 치료 중 환자의 상태 변화를 실시간 모니터링하는 시스템을 제안하였다. 또한, 환자의 요실금 정도에 따른 환자 맞춤형 자기장 치료 시스템을 제안하였다. 제안된 시스템은 자기장 발생장치, 냉각장치, 치료의자, 맥박 모니터링을 이용한 환자 감시 장치, 제어 소프트웨어로 구성되었으며, 시뮬레이션을 통한 고전력 시스템 설계 과정과 개발 후 성능 평가를 수행하였다. 제어 소프트웨어 개발을 통하여 사용의 편의성과 관리의 편의성을 확보하였으며, 환자의 증상별 치료 프로토콜을 적용하였다. 본 연구를 통하여 개발된 환자 모니터링을 포함한 환자 맞춤형 자기장 치료 시스템은 자기장 치료에서 발생할 수 있는 위험성을 줄이고, 환자의 증상에 맞게 패턴화된 치료법을 제시함으로써 요실금 자기장 치료의 효율성을 높일 수 있고, 전/후 치료를 통하여 환자에게 보다 접근된 치료법이라고 판단되었다. 이러한 결과는 요실금 환자들에게 보다 안전하고 체계적인 치료법을 제공하며, 요실금 자기장 치료 방법의 다양한 연구를 유도할 수 있을 것으로 사료되었다.

  • Objectives : Oriental Medicine Music Therapy is a new way of treating and preventing various diseases and promoting health by means of music specially picked and designed to produce Qi(氣) fitting to an individual person in the areas of the structure of human body, physiological function, pathological change, diagnosis and treatment. Therefore, it can facilitate the efficiency of the treatment much better and faster than only with herb or acupuncture. Equilibrium between body and mind is its originality. Methods : A 38-year old man came to hospital suffering from left side weakness, dysarthria because of cerebral infarction. After one week's medication in the part of neurology, he was sent to the oriental medicine music therapy center, and he took ten times' medical treatments once a day. Before and after the treatments, implementing 'Ink foot print analysis', as for the movement capacity and walking of left side weakness, these results are acquired. Results and Conclusions : 1. Before the oriental medicine music therapy, except the acceleration and deceleration section, within three meters, a right foot's step was measured 30.55 cm and a left foot was measured 15.2 cm, and the step distance was 15.2 cm. After the 10 times treatments, the right foot's step was 112.6 cm, the left foot's step was 113 cm, and the step distance improved to 51.8 cm. 2. The normal person's average step is about 38 cm, and it could be decreased owing to a decreptitude, pain, fatigue, and the weakness of the legs. In spite of all, from the increased 50 cm step measurement with the patient's body condition, it means that his movement capacity is recovered. 3. In the measurement of walking time, before 10 times treatments, it took 46.35 seconds within 6M, but after the treatments, it increased to 7.47 seconds as same as a normal person's walking speed. 4. In insomnia, and the abnormality of a facial muscle, it shows lots of improvement, and even the accuracy of a pronunciation, but despite of the 10 times treatments, the 'ㄹ(r)' sound placed under a vowel is unclear. 5. Before the 10 times' treatments, he can move the left side shoulder with pain and cannot move below the left elbow. After the treatments, the pain was disappeared, and he was able to move over 60 cm without pain. And improving of the movement of fingers, he can beat over 8 times with a drumstick.

  • Human being can't live without nature, then the changes of nature affect human body. It means that human body has corresponding changes to the KI(vital energy) of nature. There is a stream of changes in human body which circulate mysteriously and punctually by the laws of nature. If this stream of changes fits into human's life style, it would be most effective. It has a certain mode continuously. So if a person has a habit fitting into it, he will get the healthiest body. Then the researcher tries to explain the changes in human body by the time, mainly focused on within 24 hours. it is showing not only the oriental view, but also the western's. The researcher can find the coincidence as followings. At In-Si(3-5 am), the body function and the body temperature get to the bottom, therefore it's good for him to wake up and to run the vital energy. At Sa-Si(9-11 am), the patience on pain anxiety and the psychic concentration get to the top, he'd better start the work. At O-Si(11am-1pm), the heart energy has a vital move, then the blood concentration of Hb(hemoglobin) gets to the top. At Mi-Si(1-3 pm), the muscle strength, the squeeze, and the breathing rate increase. The reflex nerve sensitivity gets to the top. Creativity, observation, and working efficiency go high, so it's time to work hard. At Hae-Si(9pm-1am), the body function falls, sleeping is needed. At Chuck-Si(1-3 am), the cell spontaneity gets to the top, immune lymphocyte moves actively, and the blood concentration of growth hormone gets to the top. These are liver's work. In west, there has been active studies on how to reduce the side effect by using a person's bio-rhythm based on the 'time treatment', and how to reorganize the bio-rhythm by using the machine and the age resistance based on the 'bio-watch'. Though the 'time treatment' means something, the artificial resistance on bio-rhythm seems to give bad effects to human body. If a person lives by regimen of oriental medicine, he will maintain the healthiest body. Regimen is that human body follows the laws of nature, and moves its mysterious, Punctual and periodical changes.
