The investigation and the analysis of soil chemical properties, microbial flora and cultural practices in plastic house of 60 farms (pepper 20, cucumber 20, oriental melon 20) were conducted in Chonnam area film. An amount of fertilizer application of farms was more than that of standard fertilizer application. That was phosphate at two and a half times, potassium at twice and manure at three times the amount of standard application. It was inferred that excessive fertilizer application would lead to salts accumulation in soil. Continuous cropping injury would be incurred by excesive salts accumulation in soil. Even if inorganic elements in soil culturing peppers, cucumbers and oriental melons were greater than optimum level, base-saturation degree of soil culturing peppers, cucumbers and oriental melons was 40:18:12, 55:16:14 and 40:27:11 respectively. That was lower than the optimum levels (60:15:5). Therefore, crops would be affected by uptake inhibition by nutrition imbalance. Density of Fusarium is related to plant decease in soil i.e. pepper $26.2{\times}10^2\;cfu\;g^{-1}$, cucumber $75.8{\times}10^2\;cfu\;g^{-1}$ and oriental melon $6.5{\times}10^2\;cfu\;g^{-1}$. B/F of soil planted with pepper, cucumber and oriental melon was 91.2, 80.4 and 18.8, respectively. 시설재배 토양의 화학성, 미생물상 및 경종방법을 조사분석하여 시비관리 개선 및 연작장해의 사전 방지책 마련을 위한 자료를 얻고자 고추, 오이, 참외 재배지 60농가를 조사한 결과는 다음과 같다. 고추, 오이, 참외 재배농가의 시비량은 표준보다 인산은 2~2.5배, 칼리 2배였으며, 퇴비는 오이재배 농가에서 3배정도 많이 시용한 것으로 조사 되었으며 토양중 무기성분 함량이 대부분 적정치 이상이라 할지라도 고추, 오이, 참외 토양의 염기포화도가 40:18:12, 55:16:14, 40:27:11로 적정치의 60:15:5에 미치지 못하였을 뿐만아니라 양분 불균형으로 작물의 흡수 장해가 있었을 것으로 추정 되었다. 시설 하우스 토양의 미생물 B/F 값은 고추 91.2, 오이 80.4, 참외 18.8로 연작 년수가 긴 것으로 조사된 참외 재배토양의 미생물상이 열악한 것으로 나타났다. 토양 pH가 증가할수록 곰팡이와 Fusarium의 밀도는 감소 하고 방선균은 증가 하였으며, 토양 유기물 함양이 증가 할수록 모든 미생물의 밀도가 증가 하였으며 세균은 유의성이 안정 되었다. 세균, 곰팡이, 및 Fusarium의 밀도는 EC가 증과 할수록 감소 하였다. 따라서 시설하우스 재배시는 토양분석후 시비처방에 의해 인산과 칼리를 감비하고 염기포화도를 조절할 수 있도록 시비해야 할 것으로 사료되었다.

김희권,Kim, Hee-Gwon 대한고유수용성신경근촉진법학회 2017 PNF and Movement Vol.15 No.2

Purpose: This study compared and analyzed the effect of the proprioceptive neuromuscular facilitation (PNF) arm extension pattern and leg flexion pattern on the contralateral lower extremity muscles when the patterns were applied to the same subject. Methods: In the study, 35 healthy men and women who understood the PNF patterns were selected as participants. The participants completed the PNF arm extension-abduction-internal rotation pattern and leg flexion-adduction-external rotation with knee flexion pattern in the supine position. While the patients' completed each pattern, the contralateral leg muscle activity was measured to examine the irradiation effect. The maximum isometric contraction time of the muscles to be measured was kept for 5 seconds, and the mean value was obtained by repeating the pattern three times. Results: When the leg flexion-adduction-external rotation with knee flexion pattern was completed, the muscle activity in the vastus lateralis, vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius of the contralateral lower extremity was significantly greater than that found in the PNF arm extension-abduction-internal rotation pattern. Conclusion: The PNF leg flexion pattern showed greater muscle activity on the contralateral lower extremity than the arm extension pattern. Thus, the PNF leg extension pattern is more effective in the activation of the muscles associated with weight-bearing activity.

목적: 발작은 소아기에 상당히 흔한 임상 증상으로 급성증상성발작은 대뇌의 구조적변화, 염증, 및 대사이상 등이 원인이 될 수 있다. 대사이상을 일으킬 수 있는 대사장애 질환들로는 유기산대사이상질환군, 리소솜축적질환군, 퍼옥시솜대사이상질환군, 미량원소의 이상질환군 등이 있다. 저자들은 발작을 일으키는 유기산대사이상 질환들의 중요성을 알아보기 위하여 본 연구를 시행하였다. 방법: 2007년 1월1일부터 2011년 12월 31일까지 만 5년 동안 유기산분석이 의뢰되었던 1,306명의 환자를 2개월까지의 신생아기, 2세까지의 영아기, 12세까지의 소아기 및 12세 이후의 청소년기이후의 4군으로 나누고, 발작의 형태는 전신발작, 국소발작 및 복합발작으로 나눴으며, 발달지연의 유무에 따라 SPSS의 student's t test를 이용하여 후향적으로 분석하였다. 결과: 전체적으로 1,306명의 환자에서 유기산분석에서 비정상소견을 보인 경우가 665명(51%)이었으며, MRCD가 394명(30.1%), mandelic aciduria가 127명(9.7%), 케톤분해이상이 81명(6.2%), 3-hydroxyisobutyric aciduria가 19명(1.4%), glutaric aciduria type II가 10명(0.8%) 이었고 뒤를 이어 ethylmalonic aciduria 4명, propionic aciduria 4명이었으며, 3명의 환자가 진단된 질환들이 methylmalonic aciduria, glutaric aciduria type I, pyruvate dehydrogenase deficiency, pyruvate carboxylase deficiency 등이 있었으며, 2례씩 진단된 질환들이 isovaleric aciduria, HMG-CoA lyase deficiency, 3-methylcrotonylglycinuria, fatty acid oxidation disorders 등이 있었고, 1례씩 진단된 질환들로 fumaric aciduria, citrullinemia, CPS deficiency, MCAD deficiency 등이 있었다. 결론: 신생아기에는 감염으로 인한 mandelic aciduriad의 빈도가 의미 있게 높았고, 전연령군에서 MRCD의 중요성이 큰 것으로 파악되었다. 신생아기이후에도 다양한 유기산대사이상들의 진단이 되고 있어 기본검사의 중요성이 높았으며, 증상이 있을 때의 초기검체를 이용한 검사가 중요하다고 판단되었다. Purpose: Acute symptomatic seizures are caused by structural changes, inflammation or metabolic changes of brain, such as tumor, stroke, meningitis, encephalitis and metabolic disorders. Inherited metabolic disorders that can cause seizures are organic acidopathies, lysosomal storage disorders, peroxisomal disorders and mineral disorders. We have done this study to find out the importance of organic acidopathies causing seizure disorders in Korean childhood and adolescent patients. Method: Retrograde analysis for 1,306 patients with seizure disorders whose clinical informations are available and have done urine organic acid analysis for 5 years period, between Jan. 1st 2007 to Dec. 31th 2011. Statistical analysis was done with Student's t test using SPSS. Result: Out of 1,306 patients, 665 patients (51%) showed abnormalities on urine organic acid analysis. The most frequent disease was mitochondrial respiratory chain disorders (394, 30.1%), followed by mandelic aciduria (127, 9.7%), ketolytic defects (81, 6.2%), 3-hydroxyisobutyric aciduria (19, 1.4%), glutaric aciduria type II (10, 0.8%), ethylmalonic aciduria (4), propionic aciduria (4), methylmalonic aciduria (3), glutaric aciduria type I (3), pyruvate dehydrogenase deficiency (3), pyruvate carboxylase deficiency (3), isovaleric aciduria (2), HMG-CoA lyase deficiency (2), 3-methylcrotonylglycinuria (2), fatty acid oxidation disorders (2), fumaric aciduria (1), citrullinemia (1), CPS deficiency (1), MCAD deficiency (1). Conclusion: On neonatal period, mandelic aciduria due to infection was found relatively frequently. Mitochondrial disorders are most frequent etiologic disease on all age group, followed by ketolytic defects and various organic acidopathies. The number and diversities of organic acidopathies emphasize meticulous evaluation of basic routine laboratory examinations and organic acid analysis with initial sample on every seizure patient.
