It is known that the poor soil fertility of newly reclaimed saline soils is due to the lack of organic matter and available mineral nutrients for crop production. The effect of green manuring with Sesbania aculeata in combination with five rates of urea-N treatments (N0. N25, N50, N75, N100) on the productivity of a subsequent whole-crop barley and the fertility of the reclaimed saline soil in Saemangeum was evaluated in the field during 2013-2014 growing season. Sesbania was grown during summer season (June to October). The amount of Sesbania incorporated was 16.2 Mg ha<SUP>-1</SUP>. Sesbania contributed to 393 kg N ha<SUP>-1</SUP> to the soils when ploughed down and incorporated before whole-crop barley cultivated. The performances of whole-crop barley following sesbania incorporation were significantly affected by a combination of Sesbania manuring and different N rates. The N fertilizer equivalence without N fertilizer following Sesbania was 42.6% (63.9 kgN ha<SUP>-1</SUP>), compared with N100(150 kg N ha<SUP>-1</SUP>) in fallow soils. The whole-crop barley yield responded to N fertilizer rates in both sesbaniaamended and fallow soil. The yield response to nitrogen rates in fallow soil was linear (Y=0.0586X+3.3011, R<SUP>2</SUP> =0.9534), whereas that in sesbania-amended soils was quadratic (Y= -0.001X<SUP>2</SUP>+0.1322X+5.7143, R<SUP>2</SUP>=0.9576). The yield of whole-crop barley in sesbania-amended with increasing N rates was increased up to SN75 (115 kgN) 10.3 Mg ha<SUP>-1</SUP>. Apparent N recovery (ANR) of whole-crop barely showed decreased with sesbania plus increasing rates of N fertilizer. Despite higher yield with sesbania manuring plus increasing N rates, the contributions of N from Sesbania with increasing N rates to whole-crop barley were decreased, whereas those from fertilizer increment due to excessively mineralized Nitrogen. Considering yield, ANR, N contribution from Sesbania and nitrogen fertilizer, the optimum N rate was N50 rate following sesbania incorporation.

Objective: The study intends to investigate the influence of the grip strength and pinch power with/without the wearable wrist supporter. Background: The wearable wrist supporter is a personal protective equipment that prevent the CTS and musculoskeletal disabilities. But the researches that effectiveness of wrist supporter are few. Method: 32 university-student volunteers, 18 males and 14 females, were recruited. The factors of interest were grip strength, tip pinch power, lateral pinch power, and palmar pinch power with/without wearable wrist supporter. Results: The strength and power that use the wearable wrist supporter are greater than without the wearable wrist supporter. All results had significant difference. (p<0.05) Conclusion: Wearing the wrist supporter has advantages of hand strength during operations.

Objective: The purpose of this research is to provide exercise programs for the prevention of work related chronic back pain. Background: In order to prevent musculoskeletal disease, including proper medical care health promotion programs are needed. Method: This is a research of musculoskeletal disease looking at 618 workers working at a car engine manufacturing factory from April to July of 2008. Through questionnaire specific areas of musculoskeletal diseases experienced by the workers were identified and preventative exercise program for chronic low back pain was recommended. Result: Research showed that of the musculoskeletal disease experienced by the workers, 197 presented with low back pain, 171 presented with shoulder pain, 64 presented with neck pain and 44 presented with knee pain. The symptoms of low back pain included stiffness(143), twinge and burning sensation(24) and absence of sensation(19). Using this result 4 types of exercise programs were recommended for prevention of chronic low back pain. Conclusion: Preventative exercise programs recommended for the workers in this research is easily accessible for the workers. Use of the suggested exercise programs will inevitably decrease work related low back pain. Also 2 other recommendations were made: 1) Internal structural change may be necessary using ergonomics. 2) More exercise programs to be used to increase adaptation and tolerance of joints and muscles that are constantly used for repetitive work. Application: This study can be used to provide for the prevention of work-related Chronic Low Back pain.

배 경 : 허혈성 심질환을 유발하는 관상동맥의 동맥경화성 병변은 혈액투석 환자의 혈관 통로로 이용되는 요골동맥의 동맥경화성 병변을 빈번하게 동반한다. 허혈성 심질환 환자는 정상인에 비해 요골동맥의 내막증식증의 빈도가 높고 또한 요골동맥의 내막-중간막 두께는 더 두꺼운 것으로 알려지고 있다. 또한 연자들은 혈액투석 환자에서 요골동맥의 내막증식증은 동정맥루 조기 기능부전과 관련이 높다고 보고한 바 있다. 그러므로 허혈성 심질환이 동정맥루 조기 기능부전에 영향을 끼칠 것으로 추측되나 현재까지 이에 대한 보고가 없다. 방 법 : 첫 동정맥루 수술을 받은 125명의 비당뇨병성 혈액투석 환자를 대상으로 본 연구를 시행하였다. 당뇨병 환자와 인조혈관 사용 환자, 그리고 동정맥루 폐쇄로 재수술을 받은 환자는 대상에서 제외하였다. 이 환자들을 대상으로 수술시에 허혈성 심질환 유무를 조사하고 수술 후 1년 동안 동정맥루 기능부전을 조사하였다. 허혈성 심질환 유무에 따른 수술 후 1년 동안의 동정맥루 개통율을 Kaplan-Meier 방법과 log-rank test를 이용하여 분석하였다. 동정맥루 조기 기능부친에 대한 독립 위험인자를 조사하기 위해 다변량 회귀분석을 시행하였다. 결 과 : 대상 환자의 평균 연령은 48±14세 (15-85세)였고 남자 71명, 여자 54명이었다. 전체 125명 중에서 동정맥루 수술 전 허혈성 심질환이 있는 환자는 19명 (15.2%)이었으며 수술 후 1년 동안 동정맥루 조기 기능부전은 23명 (18.4%)에서 발생하였다. 수술 후 1년 동안의 동정맥루 개통율은 허혈성 심질환이 있는 환자 (19명)에서 39.7%로 허혈성 심질환이 없는 환자 (115명)의 88.3%로 의미 있게 낮았다 (p<0.001). 다변량 회귀분석 결과 비당뇨병성 혈액투석 환자에서 허혈성 심질환 (p<0.001)과 나이 (p=0.001)가 동정맥루 조기 기능부전의 독립 위험인자로 조사되었으며, 성별, 흡연, 고혈압, 원인 신질환, 헤모글로빈, 혈청 알부민, 총 클레스테롤은 관련이 없었다. 결 론 : 비당뇨병성 혈액투석 환자에서 동정맥루 수술 전에 동반되어 있는 허혈성 심질환은 동정맥루 조기 기능부전과 관련이 있을 것으로 사료된다. Background : Atherosclerotic lesion of coronary artery frequently accompanies intimal hyperplasia of radial artery. We have reported that the lesion of radial artery (intimal hyperplasia) in hemodialysis (HD) patients is associated with early failure of arteriovenous fistula (AVF) as well as ischemic heart disease (IHD) (Am J Kidney Dis 41:422-428, 2003). This study was designed to determine the impact of IHD on the early failure of AVF in nondiabetic HD patients. Methods : This study enrolled 125 nondiabetic HD patients who received radiocephalic AVF operation for the first time. We evaluated IHD before the operation through clinical symptom and electrocardiography and then investigated AVF failure within 1 year after the operation. We analyzed the AVF patency rates between the patients with and without IHD using Kaplan-Meier method and log-rank test. Multiple regression analysis was performed to identify independent risk factors of the AVF failure. Results : The mean age of the patients was 48±14 years and the number of female was 54 (43.2%). Of the total 125 patients, 19 patients (15.4%) had IHD before the AVF operation. The AVF failure developed in 23 patients (18.4%) within 1 year after the operation. The AVF patency rate in the patients with IHD was lower than that in the patients without IHD (39.7% vs 88.3%, p<0.001). IHD and old age were independent risk factors of the AVF failure in nondiabetic HD patients. But sex, smoking history, hypertension, and the levels of hemoglobin, serum creatinine, albumin, and total cholesterol checked before the operation were not associated with the AVF failure. Conclusion : This study suggests that IHD is closely associated with early failure of AVF in nondiabetic HD patients. (Korean J Nephrol 2004;23(1):101-107)
