본 시험은 논에서 벼 대체 여름 사료작물인 수수류를 논 재배하여 생육특성과 수량에서 우수한 품종을 선발할 목적으로 2008년부터 2009년까지 2년간에 걸쳐 충남 천안 농가 포장에서 수행하였다. 도입품종인 수수류 10품종 중에서 ‘Sordan79’는 습해에 비교적 강하고 2차 재생이 잘되며 당도가 높고 병해와 충해에 강한 생육 특성을 보였고 수량 측면에서도 생초수량이 ha 당 92,492 kg, 건물수량이 21,090kg으로 가장 우수한 품종이었다. 따라서 본 연구결과를 토대로 볼 때 중부지역에서 벼 대체 사료작물인 수수류를 논에 재배 할때는 배수가 양호한 논의 선정이 필요하고 수수류 품종 중에서는 ‘Sordan79’를 재배하는 것이 적응성이나 생산성 측면에서 가장 유리하다고 할 수 있다.
The purposes of this study were to examine inter-rater reliability of the Manual Ability Classification System (MACS) by children's age and to identify the correlation between the MACS and the Gross Motor Function Classification System (GMFCS) in children with cerebral palsy (CP). Twenty-six children with CP older than two years participated. Children with CP were classified according to the MACS and the GMFCS by two physical therapists. Inter-rater reliability was analyzed using the Intraclass Correlation Coefficients (ICCs). The results showed that the reliability of the MACS for children aged 2~3 years was .88 and for children aged above 4 years was .98 (p<.05). Children with quadriplegia had a higher level of MACS than children with spastic hemiplegia and diplegia. A moderate relationship between the MACS and the GMFCS was found in all children (rater 1, r=.631; rater 2, r=.438). The MACS will be used for classification of children with CP according to the manual abilities. Thus, it offers a reliable method for communicating between therapists about the manual ability of children with CP who are older than 2 years.
최근에 청보리 사일리지는 국내에서 가장 많이 이용하는 조사료이지만 농가에서 제조한 사일리지의 품질에 관한 분석은 거의 없는 실정이다. 따라서 본 연구에서는 2008년 사일리지 품질경연대회에 출품한 농가의 청보리 사일리지 33점의 품질을 평가하고자 실시하였다. 품질평가는 생산지역, 생산량, 첨가제 사용유무, 파종시기 및 수확시기에 따라 비교하였다. 청보리 사일리지 생산지역별 품질의 비교에서는 젖산 함량은 생산지역, 건물수량, 첨가제사용유무, 수확시기에서

This experiment was carried out to know adaptability and forage production and quality of corn and corn + soybean intercropping for silage at paddy field in Chungnam province. growth, forage production and quality of silage corn was higher in case of corn and soybean intercropping than that of corn single planting at paddy field. The height of stem of Kwangpyongok and Sword bean intercropping was somewhat lower than Kwangpyongok single planting and higher at ear height and stem diameter. Fresh yield of Kwangpyongok and Sword bean intercropping was the highest as 45.8 tons per ha among corn monoculture, corn + soybean intercropping. The dry yield of Kwangpyongok and Sword bean intercropping at paddy field was the highest as 20.5 tons per ha among corn monoculture and corn + soybean intercropping. The result of this study showed that 'Kwangpyongok and Sword bean intercropping' had good forage productivity and quality of silage compared with corn monoculture, corn and common bean intercropping.
This study was carried out between November 2007 and October 2008 in the experimental farm of Chunnam National University to investigate the effect of feeding of whole crop barley silage on the reproductive performance of Hanwoo heifers and cows. Two diets, rice straw or whole crop barley silage separately from concentrate were fed 11 Hanwoo heifers and 26 Hanwoo cows. In control group (=CON), heifers (n=6) and cows (n=13) were fed 7 kg (/head) rice straw and 4 kg (/head) commercial diet. In whole crop barley silage group (=WBG), heifers (n=5) and cows (n=13) were fed 8 kg (/head) whole crop barley silage and 1 kg (/head) commercial diet. 1. Conception rates for first service in CON or WBG heifers were 66.7% (4/6) and 60.0% (3/5), respectively, and the services per conception cows were 1.5±0.2 for CON and 1.4±0.2 for WBG group. 2. Days to post-partum insemination were 106.6±26.3 days for CON and 85.6±12.6 days for WBG group, and days to post-partum conception in CON or WBG were 128.4±27.1 and 96.8±16.8 days, respectively. 3. Post-partum conception rates for first service in CON or WBG were 76.9% (10/13) and 84.6% (11/13), respectively, and caving interval was 418.1±50.7 days for CON and 392.8±20.7 days for WBG group.
The purpose of this study was to investigate the effects of a repetitive lifting task on the level of activation and median frequency of the paraspinal muscles, and to provide basic data of the maximal acceptable duration of the lifting task to avoid muscle fatigue. Ten healthy male subjects were recruited as participants and they repetitively (12 lifts/min) lifted a box (46 ㎝ × 30 ㎝ × 30 ㎝, 15 kg) for 10 minutes. Electromyographic data (muscle activation and median frequency), heart rate, and Borg CR10 score were recorded at 1, 3, 5, 7, and 9 minutes after the lifting task. Electromyographic data was recorded from the elector spinalis, mutifidus, external oblique abdominis, and rectus abdominis for 1 minute. The results showed that as the repetitive lifting task progressed, the heart rate and Borg CR10 score significantly increased. In addition, activation of the muscles increased. The median frequency significantly decreased over time in the elector spinalis, mutifidus, and external oblique abdominis (right side), except for the external oblique abdominis (left side) and rectus abdominis. It is suggested that the median frequency recorded from a dynamic task is used to monitor muscle fatigue. Furthermore, the repetitive lifting task (15 kg, 12 lifts/min) should not continue for more than 3 minutes in order to avoid muscle fatigue.
This study investigated the irradiation pattern of muscles on the affected side in stroke patients after application of diagonal 2 extension (D2 ex) proprioceptive neuromuscular facilitation in the unaffected upper extremity. Seven stroke patients participated. Electromyographic activities were recorded in the iliopsoas, biceps brachii, and triceps brachii were recorded by surface electrodes at rest, D2 ex with knee extension, and D2 ex with knee 90 flexion, normalized by maximal voluntary isometric contraction (MVIC) values. The medial frequencies of biceps brachii in both sides were also measured to compare muscle type recruited. %MVIC of biceps brachii and triceps brachii were significantly higher in D2 ex than at rest (p<.05). There was no difference in median frequency of biceps brachii between the affected and unaffected side (p>.05). This suggests that proprioceptive neuromuscular facilitation using D2 ex may improve muscle activities of the paretic side and that the irritation pattern of the affected side may respond to maintain body equilibrium according to movement of the sound side.

The purpose of this study was to develop a checklist of risk factors for quantitative assessment of musculoskeletal complaints in shipbuilding workers. A key point was to develop comprehensive a checklist including the worker's physical ability, as ergonomic and workload factors. ln the first, through correlation analysis between musculoskeletal complaints and physical abilities in shipbuilding workers, risk factors related to physical abilities were selected. In the second, after the development of a checklist was composed of physical, ergonomic and workload factors, factor analysis was used to test the validity of the developed checklist. Each factors selected finally showed that physical factors were hand grip strength, spinal curvature, and flexibility (sit to reach), ergonomic factors were posture, total exposed time, duration, and force of working, and workload factors were physical and psychological workload perceived by worker. The results showed that musculoskeletal complaints was associated with physical abilities (p<.05). The developed checklist had a reliability of .761 (Cronbach=.761) and a validity and explanation of 54.9%. The criterion of management was classified in 4 stages by relative weights of each factor. It is suggested that active intervention is needed to reduce musculoskeletal complaints in workers with more than a 14.31 score.
