This study investigated the influence of anthropometric data and nutrient intake on bone mineral density(BMD) and biochemical markers of bone metabolism The mean age of 21 premenopausal women were 47.0 years and that of 41 postmenopausal women whose menopausal age was 49.46 years were 60.56 years. The waist and WHR of postmenopausal women were significantly higher than those of premenopausal ones. The animal protein intake of premenopausal and postmenopausal women were 38.5 and 21.03 g which comprised 54.35 and $31.84\%$ of total protein intake, respectively. The calcium intake of premenopausal and postmenopausal women were 446.45 and 546.97mg which was 63.78 and $78.14\%$ of Korean RDA, respectively. The ALP(Alkaline phosphatase) of premenopausal women was 65.81 U/L, which was significantly lower than that(90.24 U/L) of postmenopausal women (p<0.01). BMD of lumbar spine of premenopausal women was correlated significantly with body weight(r=0.690, p<0.01), waist(r=0.682, p<0.01), WHR(r=0.672, p<0.01), BMI(r=0.559, p<0.01), and body fat(r=0.457, p<0.01). Urinary Ca/creatinine ratio of the premenopausal women was negatively correlated with plant protein(r=-0.529, p<0.05) and plant calcium(r=-0.579, p<0.05). BMD of lumbar spine of postmenopausal women showed positive correlation with lean body mass(r=0.469, p<0.01) and body weight(r=0.383, p<0.05). Urinary Ca/creatinine ratio for the postmenopausal women was positively correlated with ALP(r=0.404, p<0.01) and urinary Na/creatinine ratio(r=0.389, p<0.05). In conclusion, it is necessary to maintain adequate body weight and to increase calcium intake for the premenopausal women. It is also important to increase muscle mass and reduce salt intake for the postmenopausal women.

Electroconvulsive therapy (ECT) is indicated for various mental disorders (e.g., major depressive disorder, schizophrenia, and bipolar disorder) and the behavioral and psychological symptoms of dementia in elderly patients. Furthermore, ECT is a useful first-line treatment in emergency and crisis situations such as suicide risk, violent behavior, catatonia, and food refusal, which are more frequent in elderly patients. ECT is also effective in the treatment of the motor symptoms of neurological disorders, such as Parkinson's disease and Huntington's disease. Due to the high risk of various physical diseases, the comorbid physical conditions of elderly patients should be individually controlled to optimize ECT treatment. Compared to young adults, in elderly patients the seizure threshold is higher, the seizure duration is shorter, and the anesthetic dose is lower. On the contrary, the response rate in the elderly is both faster and higher. Considering potential cognitive decline and the prevention of further deterioration of cognitive function in elderly patients, in the absence of significant comorbidities, twice weekly sessions and right unilateral electrode placement with a lower seizure threshold and less cognitive effect are preferred to bilateral electrode placement, which has a high risk of adverse cognitive effects. After an acute course of ECT, continuation and maintenance of ECT, combined with prescription of therapeutic drugs, may prevent possible relapse or recurrence of mental disorders. In conclusion, ECT can be used to treat mental disorders in elderly adults, with safety and effectiveness comparable to that in young adults.

해저터널의 그라우팅 최적 설계를 위한 수치해석적 연구

주은정,김용기,신종호,권오엽,Joo, Eun-Jung,Kim, Yong-Kye,Shin, Jong-Ho,Kwon, Oh-Yeob 한국터널지하공간학회 2010 한국터널지하공간학회논문집 Vol.12 No.5

대부분의 터널은 시간이 지남에 따라 유입량 증가, 작용수압의 변화 등 지하수의 영향을 받는다. 이러한 수리영향에 대응하기 위하여 터널 시공 시 지하수의 유입과 라이닝의 간극수압을 줄이기 위한 그라우팅을 적용한다. 본 연구에서는 효과적인 그라우팅을 위해 수치 해석결과를 바탕으로 다양한 그라우팅 조건에 대한 영향을 분석하였다. 그라우팅 영향 특성을 분석하기 위하여 그라우팅의 상대 투수계수 해석, 그라우팅의 두께, 그라우팅의 거리 등을 영향요소로 다르게 하였다. 해석결과는 지반하중, 수압, 라이닝 위치에 따른 수압, 라이닝 주변 수압분포, 유입량으로 나누어서 고찰하였다. 라이닝의 작용하는 지반 하중은 모든 조건에서 거의 동일했으며, 라이닝에 작용하는 수압은 그라우팅의 투수계수가 감소할수록, 두께가 증가할수록, 그라우팅 영역 거리가 가까울수록 감소하였다 유입량은 그라우팅 투수계수가 작을수록 감소하며, 그라우팅 두께와는 반비례한다. 본 그라우팅 영향 평가를 활용하여 지반 조건에 따른 그라우팅의 효과적인 적용을 할 수 있다. In the long-term, most tunnels suffer from the increase in ground water inflow and in pore water pressure on the lining. To reduce such hydraulic effect, generally grouting methods are adopted. In this paper effective grouting design is proposed based on numerical simulation. To investigate the optimal grouting layout, factors such as relative permeability, grouting thickness, and distance from the lining are considered. The results are analysed in terms of pore water pressure, inflow rate, and earth pressure. It is revealed that the pore water pressure has increased with a decrease in grout permeability, an increase in grouting thickness and an increase in grouting distance. Meanwhile the inflow rate has decreased with a decrease in grout permeability and is inversely proportional to grouting thickness. Effective grouting design guideline are proposed based on this study.

In recent years, many researches are actively undertaken for environmental-friendly animal production according to the increased understanding about food safety because of the outbreak of various diseases such as mad cow disease, Foot and mouth disease and Poultry Influenza virus. However, high quality(higher safety)- animal production may not be successful without increasing of disease resistance of animal and the improvement of feeding environment. To increase the disease resistance is able to be accomplished by stimulating the immune function. The present study was undertaken to investigate the effects of enzyme mixture reinforced with ${\beta}$-glucanase activity which degrade polysaccharide to release ${\beta}$-glucan known as stimulator of immune function on the change of milk production and somatic cell count. After 12weeks of experimental feeding, milk production tended to be increased and somatic cell count was decreased from average $227{\times}10^4$ to $37.1{\times}10^4$. Milk protein and solid-fat content were tended to increase but milk fat showed decreasing tendency by the feeding of enzyme mixture. All together, it has been suggest6d that the improvement of high quality milk production may be possible through the dietary addition of immune modulating enzyme mixture in lactating dairy cows.

인슐린 비의존형 당뇨병 여성환자의 혈청과 뇨중 칼슘, 아연 및 마그네슘 함량과 관련인자들과의 상관관계

주은정(Eun-Jung Joo),차연수(Youn-Soo Cha),박은숙(Eun-Sook Park) 한국식품영양과학회 1996 한국식품영양과학회지 Vol.25 No.4

인슐린 비의존형 당뇨병이 칼슘, 아연 및 마그네슘의 대사에 미치는 영향을 알아보기 위하여 인슐린 비의존형 당뇨병 여성환자 19명과 정상 성인 여성 19명을 대상으로 식이 섭취량을 조사하고, 칼슘, 아연 및 마그네슘의 혈청 농도와 24시간 뇨중 배설량을 측정하였다. 그리고 혈당조절 지표로서 이용되는 공복시 혈당, 뇨중 포도당, 혈청 알부민, 뇨중 단백질을 정량하여 혈청과 뇨중 칼슘, 아연 및 마그네슘 함량과의 상관관계를 살펴보았으며, 그 결과는 다음과 같다. 혈청 중 칼슘 함량은 당뇨병군이 1.17±0.56mmol/L로서 정상인의 2.53±1.39mmol/L 보다 유의적(p<0.01)으로 낮았으며, 뇨중 칼슘은 반대로 당뇨병군이 235.81±66.17㎎/g.cr으로 정상인의 96.08±46.74㎎/g.cr 보다 유의적 (p<0.01)으로 증가하였다. 뇨중 아연과 마그네슘 배설량은 당뇨병군이 516.11±157.31㎍/g.cr과 76.05±31.26㎎/g.cr 보다 유의적(p<0.01)으로 증가하였으나, 혈청 중 아연과 마그네슘 함량은 차이가 없었다. 당뇨병 환자에 있어서 혈청 중 마그네슘은 공복시 혈당(r=-0.533 ; p<0.05), 뇨중 포도당(r=-0.767 ; p<0.001), 뇨중 단백질(r=-0.476 ; p<0.05)과 뇨중 단백질(r=0.568 ; p<0.05)과 양의 관계가 있었다. 당뇨병환자에 있어서 혈청 아연 함량은 뇨중 단백질과 상관관계(r=0.515 ; p<0.05)가 있으며, 뇨중 아연은 뇨중 단백질(r=-623 ; p<0.01) 및 혈청 알부민(r=0.579 ; p<0.01)과 양의 관계를 나타내었다. 당뇨병 환자에 있어서 공복시 혈당은 유병기간(r=0.595 ; p<0.05)과 양의 관계가 있었으며, 식이중 지방 및 열량 섭취량(r=0.595 ; p<0.05, r=0.489 ; p<0.05)과도 상관관계를 나타내었다. 그러므로 인슐린 비의존형 당뇨병 환자의 뇨중 칼슘, 아연 및 마그네슘의 배설이 정상인에 비하여 유의적으로 증가한 것은 같은 현상으로 보이지만, 혈당 조절인자와의 관계는 각각 다르게 작용하고 있었다. 특히 마그네슘이 혈당조절인자와 가장 밀접하게 관련되어 있음을 알 수 있다. Nineteen non-insulin-dependent diabetic(NIDD) and healthy control women were investigated to study the relationship between glycemic control and the level of calcium, zinc, and magnesium in the serum and urine. Urinary calcium, zinc and magnesium levels in the NIDD women were significantly higher(p<0.01) than those of the control women. There were no difference in serum magnesium and zinc levels between the two groups, but serum calcium level was lower(p<0.0l) in the NIDD women compared to that of the control group. In the NIDD women, serum magnesium was negatively related to fasting blood glucose(r=-0.533 ; p<0.05), urinary glucose(r=-0.767 ; p<0.001), urinary protein(r=-0.476 ; p<0.05), and urine volume(r=-0.571 ; p<0.05). The levels of zinc in both serum(r=0.515, p<0.05) and urine(r=0.623 ; p<0.01) were related to urinary protein but only urinary zinc level(r=0.570 ; p<0.01) was related to serum albumin. Urinary magnesium, not calcium was correlated with the urinary glucose(r=0.563 ; p<0.05) and urinary protein(r=0.568 ; p<0.05). Fasting blood glucose was positively correlated with duration of diabetes, as well as dietary fat and calorie intake. The results of this study suggest that NIDD alters all magnesium, zinc, and calcium utilization, particularly magnesium is involved in glycemic control in this condition.
