  • This research has conducted studies on an Oriental medicine-based method of diagnosing of occupational musculoskeletal system diseases. This researcher has searched through existing relevant medical literature. Also, this researcher has worked on a moire topography using moire topography. In this course, this researcher has reached the following conclusion in relation to the possibility of using a moire topography as a diagnosing device of musculoskeletal system diseases under Oriental medicine . 1 The Western medicine outlines its criteria of screening occupational musculoskeletal system diseases as follows A. The occupational musculoskeletal diseases must clearly include one or more of the subjective symptoms characterized by pain, hypoesthesia dysaesthesia, anaesthesia. etc . B, There should be clinically admitted objective observations and diagnosis outlining that the disease concerned shows symptoms such as tenderness, induration. and edema that can appear with occupational musculoskeletal system diseases. dyscinesia should be admitted with the disease concerned, or there should be observations and diagnosis outlining that abnormality exists in electric muscular or nervous diagnosis and examination . C. It should be admitted that prior to the occurrence of symptoms or observations and diagnosis on musculoskeletal system-related diseases, a patient has been engaged in works with conditions requiring improper work posture or work movement. That is, this is an approach whereby they see abnormality in the musculoskeletal system come from material and structural defect, and adjust and control abnormality in the musculoskeletal system and secreta . 2. The Oriental medicines sees that a patient develops the pain of occupational musculoskeletal diseases as he cannot properly activate the flow of his life force and blood thus not only causing formation of lumps in the body and blocking the flow of life force and blood in some parts of the body. Hence, The Oriental medicine focuses on resolving the cause of weakening the flow of life force and blood, instead of taking material approach of correcting structural abnormality Furthermore , Oriental medicine sees that when muscle tension builds up, this presses blood vessels and nerves passing by, triggering circulation dyscrasia and neurological reaction and thus leading to lesion. Thus, instead of taking skeletal or neurophysiological approach. it seeks to fundamentally resolve the cause of the flow of the life force and blood in muscles not being activated. As a result Oriental medicine attributes the main cause of musculoskeletal system diseases to muscle tension and its build-up that stem from an individual's long formed chronicle habit and work environment. This approach considers not only the social structure aspect including companies owners and work environment that the existing methods have looked at, but also individual workers' responsibility and their environmental factors. Hence, this is a step forward method. 3 The diagnosis of musculoskeletal diseases under Oriental medicine is characterized by the fact that an Oriental medicine doctor uses not only photos taken by himself, but also various detection devices to gather information and pass comprehensive judgment on it. Thus, it is the core of diagnosis under Oriental medicine to develop diagnosing devices matching the characteristics of information to be induced and to interpret information so induced from the views of Oriental medicine. Diagnosis using diagnosing devices values the whole state of a patient and formal abnormality alike, and the whole balance and muscular state of a patient serves as the basis of diagnosis. Hence, this method, instead of depending on the information gathered from devices under Western medicine, requires devices that provide information on the whole state of a patient in addition to the local abnormality information that X-ray. CT, etc., can offer. This method sees muscle as the central part of the abnormality in the musculoskeletal system and thus requires diagnosing devices enabling the muscular state. 4. The diagnosing device using moire topography under Oriental medicine has advantages below and can be used for diagnosing musculoskeletal system diseases with industrial workers . First, the device can Provide information on the body in an unbalanced state. and thus identify the imbalance and difference of height in the left and right stature that a patient can not notice at normal times. Second, the device shows the twisting of muscles or induration regions in a contour map. This is not possible with existing shooting machines such as X-ray, CT, etc., thus differentiating itself from existing machines. Third, this device makes it possible for Oriental medicine to take its unique approach to the abnormality in the musculoskeletal system. Oriental medicine sees the state and imbalance state in muscles as major factors in determining the lesion of musculoskeletal system, and the device makes it possible to shoot the state of muscles in detail. In this respect, the device is significant. Fourth, the device has an advantage as non-aggression diagnosing device.

  • 일반적으로 요중 카드뮴 농도는 요비중 또는 요중 크레아티닌 농도로 보정한 값을 사용해왔다. 그러나 어떤 보정방법이 더 타당한지에 대한 논란은 계속되고 있다. 본 연구에서는 비교적 큰 규모의 일반인구집단을 대상으로 요중 카드뮴농도와 각종 신장손상지표들과의 관련성을 평가함에 있어 요비중 보정 방법과 요중 크레아티닌 보정 방법 중 어느 방법이 더 타당한지 비교 평가하였다. 1,086명의 자원자 중 신장질환의 질병력이 있는 사람을 제외한 862명이 최종적으로 연구대상에 포함되었다. 대상자들로부터 측정한 요중 카드뮴 농도 및 malondialdehyde (MDA), N-acetyl-${\beta}$-D-glucosaminidase 농도, 혈중 크레아티닌을 이용하여 산출한 사구체여과율 등의 신장손상지표들간의 관련성을 평가하였다. 연구 결과, 요중 크레아티닌 농도보다는 요비중으로 보정한 카드뮴 농도가 각종 신장손상지표와 높은 상관성이 있음을 보여주었다. 특히, 요비중 보정 카드뮴 농도는 요중 MDA 농도와 양의 상관관계를, 사구체여과율과는 음의 상관관계를 보여주었다. 이러한 결과는 일반인구집단에서 카드뮴 노출이 많아질수록 사구체여과율이 감소함을 의미하며 이러한 기전에서 산화적스트레스가 관여하고 있음을 보여준다. 또한, 사구체여과율이 카드뮴 노출에 의한 유용한 신장손상지표 중 하나로 사용될 수 있음을 의미한다.

  • 본 연구에서는 충주댐($2750{\times}10^6m^3$) 및 조정지댐($30{\times}10^6m^3$)을 포함한 유역을 대상으로 미래 기후변화가 댐 저수량에 미치는 영향을 분석하기 위해 SWAT(Soil and Water Assessment Tool) 모형을 활용하였다. 3지점의 9개년(2002~2010)동안의 자료를 이용하여 검보정을 실시한 결과 유출량에 대해서는 Nash-Sutcliffe 모델 효율(NSE)이 0.73으로, 두 댐의 저수위에 대해서는 0.86으로 나타났다. 미래 기후변화 시나리오자료는 IPCC(Intergovernmental Panel on Climate Change)에서 제공하는 GCMs (General Circulation Models) 중 HadCM3 모델의 SRES(Special Report on Emission Scenarios)에 의한 B1과 A2 시나리오를 구축하였다. 미래 월별 기온과 강수자료는 과거 30개년(1977~2006, baseline period) 자료는 편의보정(bias-correction) 기법을 이용하여 오차보정 후, Change Factor (CF) method를 이용하여 상세화 하였다. 미래 연평균 기온은 2040s (2031~2050)에 $0.9^{\circ}C$, 2080s (2071~2099)에는 $4.0^{\circ}C$까지 증가할 것으로 예측되었고, 연평균 강수량은 2040s에 9.6%, 2080s에 20.7% 증가하는 것으로 나타났다. 과거 대비 미래 증발산량은 15.3%까지 증가하고, 토양수분은 최대 2.8% 감소하였다. 과거 9개년 평균 댐 방류스케줄에 따른 미래 댐 연평균 유입량은 가을철을 제외한 대부분 기간에 최대 21.1%까지 증가하는 경향을 보였다. 미래 가을철 댐 유입의 감소로 인해 현재 방류 패턴으로는 연말까지 결국 저수량을 회복하지 못하는 것으로 나타났다. 미래 풍수년과 갈수년에는 댐 저수량의 시간적 변동이 더욱 불안정해지므로 각각 저수량의 상향 및 하향 조정에 주의를 기울여야 한다. 따라서 기후변화 적응을 위한 댐 방류 패턴 조절이 필요하다고 판단된다.
