The purpose of this study was to evaluate the effects of quadriceps femoris flexibility exercise which would improve the degree of knee flexion range of motion, extension torque, and the activities of daily living (ADL) in elderly subjects with degenerative knee arthritis. Fourteen elderly patients (two men and twelve women) with degenerative knee arthritis participated and had a quadriceps femoris flexibility exercise intervention program in this study. The mean age of the patients was 70.00 years for men and 71.16 years for women. This study carried out the experimental study of one group pretest-posttest design, which evaluated the degree of knee flexion range of motion, extension torque, the ADL ability of the patients before and after applying the exercise intervention for five weeks. The results of this study are as follow: 1. The knee flexion ranges of motion of the patients were measured before and after the intervention and the ranges increased significantly both in the left and right knee flexion range of motion (p < 0.05). 2. The peak torque of the knee muscle, the peak torque/body weight, and average power of the patients showed significant increases in both in the left and right knee after applying the intervention (p < 0.05). 3. The intervention produced a significant reduction in pain of the patients (p < 0.05). Their functional activities of ADL improved significantly compared with before the intervention (p < 0.05). It has been shown that the quadriceps femoris flexibility exercise intervention program increased significantly the knee flexion range of motion, and extension torque, as well as an increase in performance of functional activities of ADL of the patients. Thus, the quadriceps femoris flexibility exercise should be considered as one of the therapeutic exercises for the elderly patients with degenerative knee arthritis applied.

The purpose of this study is to investigate effects of Maitland orthopedic manipulative physiotherapy and stretching on pain, cervical range of motion, and muscle tone of adults with forward neck posture. A total 40 subjects were divided into a Maitland OMPT group(n=20) and a stretching group(n=20), performing joint mobilization exercise and stretching three times per week for six weeks. As for changes in pain, statistically significant decrease were found before and after the exercise within group comparison(p<.01), while no statistically significant difference was observed between-group comparison. In changes in cervical range of motion before and after the exercise, the Maitland OMPT group showed statistically significant increase(p<.01) in flexion, (left lateral flexion(p<.05), extension, left rotation, right rotation, and right lateral flexion, while the stretching group showed statistically significant increase(p<.05) in extension(p<.01), left rotation, left lateral flexion, right rotation, and right lateral flexion. However, no significant differences in between group comparison in flexion, extension, right rotation, left rotation, right lateral flexion and left lateral flexion. The results of measuring muscle tone changes showed that the Maitland OMPT group and the stretching group did not show significance in within and between group comparison(p<.05). In conclusion, the Maitland OMPT and stretching were effective on improving pain and range of motion.

This study was conducted with the data of monitoring on soil chemical properties of rice paddy soils in Gyeongbuk Province. The selected soil chemical properties were analyzed every 4 year from 1999 to 2015. The soil pH measured in 2015 was higher than pH 6.0, which was 0.3-0.4 pH unit higher than data until 2007 survey year. The mean content of organic matter was greater than $24g\;kg^{-1}$ since 2003, but 35% of soil samples remained below the recommended level ($20-30g\;kg^{-1}$) in 2015. The mean concentration of available phosphate was maintained at $40mg\;kg^{-1}$ higher than the upper recommendation level ($80-120mg\;kg^{-1}$), and more than 40% of paddy soils tested were found to have less than the recommendation level during the survey period. The exchangeable K concentration ranged from 0.25 to $0.39cmol_c\;kg^{-1}$. Exchangeable Ca showed an average at the optimum range ($5.0-6.0cmol_c\;kg^{-1}$) during the monitoring period. Exchangeable Mg decreased linearly ($0.02cmol_c\;kg^{-1}\;year^{-1}$) from $1.55cmol_c\;kg^{-1}$ as of 1999 to below the lower level of the recommendation range ($1.5-2.0cmol_c\;kg^{-1}$). The amount of available $SiO_2$ was increased significantly from 2011 to over the recommendation level (${\geq}157mg\;kg^{-1}$). It was revealed that the soil chemical properties of rice paddy fields was influenced by topology, soil texture, type and region as result of principal component analysis or cluster analysis. Therefore, an assessment on chemical properties of rice paddy soils should be performed to consider various soil physical conditions and agronomic practices such as fertilization, cropping system, and so on. Because of the high variability of nutrient levels across Gyeongbuk Province, nutrient management based on soil fertility test is required by respective farm land unit.

PURPOSE: The purpose of the study was to investigate a influence in Proprioceptive Neuromuscular Facilitation, and self-assisted ROM exercise of shoulder adhesive capsulitis. METHODS: The methods of the study was to investigate a change in range of motion (ROM), an increase in ROM, visual analogue scale (VAS) and disability questionnaire by Proprioceptive Neuromuscular Facilitation, and self-assisted ROM exercise on 32 patients who were diagnosed with shoulder adhesive capsulitis. RESULTS: There was no significant difference between the two groups who were treated in the Proprioceptive Neuromuscular Facilitation and self-assistive ROM exercise group for flexion, extension, internal rotation, external rotation, VAS and disability questionnaire. Both group's flexion, extension, internal ratation, and external rotation levels were significantly different before and after the treatment. And significant statistical decrease in VAS and disability was seen. The extension of the shoulder joint was closely related to external rotation (r=0.84). There was a close relationship between internal rotation and external rotation at the shoulder joint. There was no increased range of extension through the exercise method. However, flexion, extension, internal rotation, external rotation, VAS, and disability questionnaire of Proprioceptive Neuromuscular Facilitation groups were obviously higher than in the self-assisted ROM exercise group. CONCLUSION: Our study suggest that considering Proprioceptive Neuromuscular Facilitation for the patient who has shoulder adhesive capsulitis in clinic.

The lack of close working relationship between agricultural research, extension organizations and farmers, is one of the most difficult problems confronting agricultural technology system. Systems approach is an effective method to use in indentifying lingkage problems in agricultural technology system, and it is a problem-solving methodology. There are two basic types of linkage mechanisms; organizational and managerial. Organizational mechanisms involve the structural modification of the research and extension organizations involved in an agricultural technology system. The other major type of lingkage mechanisms involves a range of managerial interventions such as joint planning and review activities, collaborative program activities, and resource allocation procedures, etc.

The monitoring of chemical dynamic changes in controlled horticultural lands is very important for agricultural sustainability. Field monitoring was performed to evaluate the soil chemical properties of 200 controlled horticultural soil samples in Gyeongnam province every 4 years from 2000 to 2012. Soil chemical properties such as pH, amount of organic matter, available phosphate, nitrate nitrogen, and exchangeable potassium, calcium, magnesium, and sodium were analyzed. The amount of exchangeable calcium and soil pH were significantly higher in 2012 than in 2000. In 2012, the frequency distribution for values of pH, organic matter, available phosphate, and exchangeable potassium, calcium, and magnesium that were within the optimum range was 16.0%, 22.5%, 11.5%, 3.5%, 2.5%, and 5.0%, respectively. Especially, available phosphate and exchangeable calcium were excess level with portions of 76.0% and 96.5%, respectively. These results indicated that a balanced management of soil chemical properties can reduce the amount of fertilizer applied for sustainable agriculture in controlled horticultural lands.

Gradient vector flow(GVF) snake 또는 active contour 모델은 영상 분할에서 훌륭한 성능을 보여준다. 그러나 기존의 snake 모델에는 제한된 캡쳐 영역과 요면으로의 느린 진행과 같은 문제점들이 존재한다. 본 논문은 주변의 필드로부터 외부장(external force field)을 확장시키고 변형된 평탄화기법을 이용하여 확장된 필드를 정규화 함으로서 GVF snake 모델의 성능을 개선시키는 새로운 방법을 제시한다. 시뮬레이션을 위해 사용된 U자 모양 이미지에서의 결과는 제안된 방법이 좀 더 큰 캡쳐 영역을 갖고 기존의 GVF snake 모델에 비하여 요면으로 빠르게 진행하는 것이 가능함을 보여준다.

This research analyzes the relationship between the height of the sleeve cap and the mobility of arm movement. Ten Korean women participated as subjects. For test clothes, the AH/4+3, AH/4+1, and AH/4-1 height of the sleeve cap were varied. The sleeve circumference was adjusted according to the variation of the height of the sleeve cap. To analyze test clothing objectively, the range-of-motion of two selected movements (Arm Adduction/Abduction and Arm Flexion/Extension) was measured by Leighton flexometer and goniometer. Also, a wearer acceptability rating was examined for acceptance by the subject. Anova and Duncan's multiple range tests are used for statistical analysis. According to the results, the mobility of test clothing 2 and 3 improved 14.9% and 27.7% in Arm Adduction/Abduction, and 12.7% and 31.9% in Arm Flexion/Extension compared to the test clothing 1.
