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.

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.

배 경 : 본태성 고혈압 환자의 10-40%에서 경도의 신기능 저하를 동반하는 것으로 보고되어 있으며, 고혈압 환자에서 신부전이 동반된 경우 심혈관 사망률이 높은 것으로 알려져 있다. 본 연구에서는 내원 당시 중증 고혈압과 동반된 신부전 소견을 보였으나, 적극적인 혈압 조절 후 신기능의 호진을 보인 환자들의 임상 특징을 분석해 보고자 하였다. 방 법 : 1993년 1월부터 2002년 12월까지 10년간 가톨릭의대 강남성모병원 및 성바오로병원에서 중증 고혈압 및 신부전증 (혈청 크레아티닌치 2.0 ㎎/dL 이상)으로 진단된 환자들 중에서 혈압 조절 후 신기능의 호전 (혈청 크레아티닌의 감소)을 보인 환자들을 대상으로 이들의 평균 동맥압 및 혈청 생화학 검사치 변화를 분석하고, 신생검 소견 및 투어 혈압 약제를 분석하였다. 결 과 : 전체 14명의 환자 중 남자는 8명 여자는 6명이었고, 이들의 평균 연령은 38±8세 였다. 평균 동맥압의 유의한 감소와 더불어 혈청 크레아티닌치의 감소 (p=0.001)와 헤마토크리트치의 유의한 증가 (p=0.001) 소견이 관찰되었다. 그러나 혈청 요산, 총콜레스테롤, 중성지방 농도의 유의한 변화는 없었다. 신초음파 검사상 정상 신장 크기를 보인 경우는 12명 (80%)이었고, 대상 환자군은 대부분 3가지 이상의 항고혈압제를 병합 투여하여 적극적인 혈압 조절을 하였으며, 전환효소차단제 및 안지오텐신 Ⅱ 수용체 길항제 (22%), 칼슘통로차단제 (21%), 베타차단제 (21%)를 주로 투여하였다. 신생검을 시행한 6예를 분석한 결과, 4예는 고혈압성 신경화증, 2예는 IgA 신증으로 진단되었다. 6예 모두 신세동맥의 초자질 침착과 혈관내피의 점액양 변성을 동반한 신세동맥의 비후 소견이 존재하였고, 경도에서 중등도의 세뇨관 위축 소견과 간질성 섬유화 소견이 관찰되었다. 결 론 : 신부전을 동반한 중증 고혈압 환자들 중, 신장 크기가 정상이고 나이가 젊은 환자의 경우, 혈압 조절을 통해 신기능을 호전시킬 수 있으므로, 이들에 대한 적극적인 혈압 조절이 필수적이라 하겠다. Background : Mild renal dysfunction is relatively common in patients with long standing primary hypertension, ranging from 10% to 40% in various studies. The presence of renal dysfunction is associated with high cardiovascular mortality and morbidity rates of patients with primary hypertension. The purpose of this study is to analyze the clinical characteristics of patients with severe hypertensin and reversible renal dysfunction after blood pressure control. Methods : This retrospective study enrolled 14 patients with severe hypertension and reversible renal dysfunction after blood pressure control, between January 1993 and December 2002 at Kangnam St. Mary`s Hospital and St. Paul`s Hospital. We investigated the laboratory data using Wilcoxon signed rank test, and analysed renal biopsy findings and antihypertensive drugs. Results : The mean age of the patients was 38±9 years and the number of male patients was 8. During 33.5±28.8 months of mean follow-up period, there was a significant decrease in mean arterial pressure and serum creatinine level, and significnat increase in hematocrit level. But there was no significant changes in the level of uric acid, total cholesterol, and triglyceride. Each patient took more than 3 antihypertensive drugs consisting angiotensin converting enzyme inhibitor or angiotensin Ⅱ recep색 blocker (22%), calcium channel blocker (21%), and beta blocker (21%). Renal biopsy was done in 6 cases, and histologic diagnosis resulted in 4 cases of benign hypertensive nephrosclerosis and 2 cases of IgA nephropathy. The typical morphological features of hypertensive nephrosclerosis were seen in all cases, and there were varying degrees of glomerular sclerosis from 0% to 92%. But the percent of glomerular sclerosis was not related to the level of initial serum creatinine, mean arterial pressure, and amount of proteinuria per day. Conclusion : Careful monitoring of renal function and effective treatment of blood pressure are therefore mandatory in treating young patient with severe gypertension with renal dysfunction.
