정동원 ( Dong Won Jeong ),한종호 ( Jong Ho Han ) 한국물류학회 2012 물류학회지 Vol.22 No.2

물류산업은 경제 발전에 중요한 역할을 담당하며, 산업경쟁력과 국가경쟁력을 결정하는 중요한 요소로 작용하고 있다. 본 논문에서는 산업연관분석을 이용하여 물류산업의 국민경제적 파급효과를 분석하고자 한다. 먼저 수요유도형 모형을 이용하여 물류산업의 타 산업 생산유발효과, 부가가치 유발효과, 취업유발효과를 살펴본다. 다음으로 상대적으로 복잡성 때문에 잘 사용되지 않았던 공급유도형 모형 및 레온티에프 가격모형을 적용하여 물류산업의 공급지장효과 및 물가파급 효과를 살펴본다. 이러한 분석은 모두 물류산업을 내생부문이 아닌 외생부문으로 다룸으로써 물류산업을 중심으로 이루어지게 된다. 주요 분석결과를 요약하면 다음과 같다. 물류산업의 1원 생산은 타 산업의 생산을 0.5104원만큼 유발하며, 타산업의 부가가가치를 0.1722원만큼 유발한다. 또한 물류산업의 10억원 생산은 타산업에서 2.2554명의 취업을 유발한다. 한편 물류산업에서 1원의 공급이 이루어지지 못할 때, 타 산업에서는 0.9387원의 생산차질이 발생하여 공급지장효과가 제법 큰 편이다. 마지막으로 물류산업의 가격이 10& 상승했을 때, 국민경제 전체적으로 미치는 물가파급효과는 0.0276%로 분석되었다. The logistics industry in Korea plays a major role in the national economy development and to make decision nation and industrial competitiveness, This study attempts to examine the economic impacts of the logistics industry using an inter-industry analysis, Specially, the study investigates production-inducting effect, value added inducing effect, and employment-inducing effect of the logistics industry based on demand-driven model. Moreover, the study deals with supply shortage effect and sectoral price effect by using supply-driven model and leontief price model, respectively, which have been rarely used because of their complications involved in computaiton. These analyses pay particular and close attention to the distribution industry by taking it as exogenous rather than endogenous. Some interesting findings emerge from the study. First, the production of 1.0 won in the logistics industry induces the production of 0.5104 won and the value-added of 0.1722 won in other industries. Second, the production of 1.0 billion won in the logistics industry causes the employment of 2.554 persons in other industries. Third, the supply shortage of 1.0 won in the logistics industry disables other industries to produce 0.9387 won. Finally, an increase of 10% in price level of the logistics industry raises the overall price level by 0.0276%.

N/A This study employed 11 university soccer players for assessing anaerobic capacities related to ATP-PC and/or lactate system. It was investigated correlation among anaerobic capacities from Critical Power test, from Wingate test, and from Isokinetic test. Also, the study investigated regression formula which could expect anaerobic reserve(AR) from variables measured in Wingate and Isokinetic test. There were significant but intermediate correlation between AR and WIN5, (r= .62, P< .05) and WIN30(r= .64, P< .05). There was no statistically significant but intermediate correlation between AR and WIN10 (r= .52, P> .05). The study used stepwise method for multiple regression by Wingate variables to produce AR. The result showed that WIN30 had significant effect and indicated regression formula (Y= 1.3323(WIN30)-14737.758) to explain 41.2% variation of AR. Stepwise method was done for multiple regression on Isokinetic variables to produce AR`s inferred possibility by extensors TW of 60˚ /sec as regression (Y= 10.6737 (TW)+2083.9403) explained 42.9% variation of AR. In the correlation between measured variables of Wingate and Isokinetic extensors there was no significance of intermediate correlation in 60˚ /sec PT and WIN5(r= .53, P> .05) and in TW and WIN5(r= .56 P< .05) statistically. Also, There was significance of intermediate correlation in PT and WIN10 (r= .65, P< .05), no significance in TW and WIN10 (r= .57, P> .05), in PT and WIN30(r= .58), and no significance in TW and WIN30(r= .46, P> .05). In the correlation between measured variables of Wingate and Isokinetic extensors, there was significance of intermediate correlation in 180˚ /sec PT and WIN10 (r= .69, P< .05) and significant correlation in Isokintic 180˚ /sec PT and WIN30(r= .65, P< .05). The data suggested that anaerobic reserve assess true anaerobic ability not including the energy component of anaerobic glycolyses. Also, the study provides preliminary data on the anaerobic abilities in university soccer players as assessed by the Critical Power test, Wingate test, and Isokinetic test.

To induce bone formation at ectopic site by tissue engineering and gene therapy, we transplanted collagen sponges containing rhBMP-7 transduced HEK 293 cells in the hypodermis of nude mice. Bone formation was investigated by histological and electron microscopic method at 3, 6, and 9 weeks after transplantation. At 9 weeks after transplantation, eosinophilic bony tissue was observed in the implanted collagen sponge and was confirmed as bone tissue by Von Kossa stain. In the transmission electron microscopic observation, the cells in newly formed bone tissue had eccentrically located nucleus and well developed rough endoplasmic reticulum (rER). Therefore, the cells were evaluated as osteoblasts. Those results suggest that it is possible to form a bone tissue in the ectopic site by transplantation of rhBMP-7 transduced HEK 293 cells. This will be contributed to push more advanced gene therapy for bone formation. However, the HEK 293 cell is unable to apply to the clinical gene therapy. Therefore it is worth to find more compatible cells for clinical application. In addition, collagen sponge is considered as an excellent scaffold and/or carrier for gene therapy and a good biomaterial for tissue engineering.

Since in 1970, the length of concrete pavements(JCP, JRCP and CRCP) are growing rapidly at both of main highways and local roads. Many of them are deteriorated and old enough to be repaired or replaced. The pavement is more important than the other infrastructures and it is very difficult to go around or block the traffic during the rehabilitation. The very-early strength latex-modified concrete(VES-LMC)may offer the advantages of high-early-strength, higher flexural strength, higher bond strength, and improved durability. The VES-LMC could be used at a kind of fast track ofr early opening to the traffic after 3 hours of concrete placement. The installation of VES-LMC overlay at Jung-Boo highway was successfully done from April 28 to 29, 2005. The traffic was closed at 07:00 PM and opened to traffic at 08:30 AM. The compressive and flexural strength of VES-MC were more than 28MPa, 6.2MPa after 4 hours, respectively.

일부 지역 주민에서 초기 신기능 저하의 지표로서 혈청 Cystatin C 농도의 유용성

원기범,김준섭,박준형,강혁주,이정호 동국대학교 의학연구소 2009 東國醫學 Vol.15 No.2

혈청 cystatin C농도는 혈청 creatinine농도에 비해 신기능을 정확히 반영한다고 알려져 있지만, 대규모 연구 자료가 제한적이었다. 따라서 저자는 다수의 일부 지역 주민을 대상으로 cystatin C를 creatinine과 비교하여 신기능의 지표로서 cystatin C의 유용성을 알아보고자 하였다. 2008년 7월부터 9월까지 포항지역의 건강 검진자 999명 (남자: 324명, 여자: 657명)을 대상으로 혈청 cystatin C, 혈청 creatmine, 나이, 체중을 측정하고, Cockcroft-Gault식으로 사구체 여과율을 계산하였다. 계산된 사구체 여과율을 National Kidney Foundation의 Kidney Disease Outcomes Quality Initiative (KDOQI)에서 제시한 만성 신장병 분류 기준에 따라 5단계로 분류하였지만 4단계 (중증의 사구체 여과율 저하) 및 5단계 (신부전 또는 투석) 에 포함되는 대상자들의 숫자가 적어 (4단계: 4명, 5단계: 1명) 연구 대상에서 제외하였다. 대상자들의 평균 나이는 52.1 ± 17.1 세, 평균 체중은 59.7 ± 11.3 Kg,평균 혈청 cystatin C농도는 0.9 ± 0.2 mg, 평균 creatinine 농도는 1.0 ± 0.2 mg/dL이었다. 사구체 여과율을 각 단계별로 비교해 본 결과는 다음과 같이 혈청 cystatin C농도는 1 단계 (정상 신기능)는 0.8 ± 0.1 mg, 2단계 (경도의 신기능 저하)는 0.9 U 0.1 mg, 3단계 (중등도의 신기능 저하)는 1.0 d=0.1mg로 각각 유의한 차이를 보였다 (p<0.05).혈청 creatinine농도는 1단계는 0.9 ± 0.2 mg/dL, 2단계는 0.9 ± 0.1 mg/dL, 3단계는 1.0 ± 0.1 mg/dL로 l단계와 2단계 간에 차이가 없었으나 (p>0.05), 2단계와 3단계 간에는 유의한 차이를 보였다 (p<0.05).혈청 cystatin C농도와 혈청 creatinine농도는 나이 (cystatin C: r=0.275, p<0.05; creatinine: r=0.300, p<0.05) 및 체중 (cystatin C: r=0.075, P<0.05; creatinine: r=0.162, p<0.05) 과 양의 상관 관계를 보였다. 혈청 cystatin C 농도는 성별 간의 차이가 없었고, 혈청 creatinine농도는 남성에서 유의하게 높았다. 혈청 cystatin C농도는 혈청 creatinine농도에 비해 초기 신기능 저하를 반영하는 유용한 지표라고 생각된다. Although serum cystatin C has been suggested to be a better alternative marker than serum creatinine for estimating renal function, there have been limited data about its superiority over creatinine in a large number of populations. The aim of this study was to evaluate cystatin C as a renal marker compared to creatinine in a large population of the local community. We measured serum cystatin C, creatinine, age, body weight from 999 volunteers (Male; 324, Female; 657) of a single local cohort, Phohang, from July to September, 2008, and then calculated the GFR according to Cockcroft Gault(CG) formula. The population was divided into five stages followed by the chronic renal disease classification presented by KDOQI. The numbers in stage 4 (severe renal impairment), and 5 (renal failure) were too small (4 in stage 4, 1 in stage 5) to perform statistical analysis, so we excluded them. The mean age was 52.1 ± 17.1, and body weight 59.7 ± 11.3 Kg; serum cystatin C 0.9 ± 0.2 mg/L; serum creatmine 1.0 ± 0.2 mg/dL; CG GFR 70.6 ± 19.1 ml/min/1.73 m^(2). The tests completed for the comparison among each stage suggested the following results; serum cystatin C levels in stage 1 (normal renal function), stage 2 (mild deterioration of renal function), and stage 3 (moderate deterioration of renal function) showed the significant differences (stage 1 vs 2: 0.8 ± 0.1 vs 0.9 ± 0.1, p<0.05; stage 2 vs 3: 0.9 ± 0.1 vs 1.0 ± 0.1, p<0.05). Serum creatinine levels showed no significant differences between stage 1 and stage 2 (stage 1 vs 2: 0.9 ± 0.2 vs 0.9 ± 0.1, p>0.05), but showed significant differences between stage 2 and stage 3 (stage 2 vs 3: 0.9 ± 0.1 vs 1.0 ± 0.1, p<0.05). Serum cystatin C and creatinine presented positive correlation between age (cystatin C: r=0.275, p<0.05; creatinine: r=0.300, p<0.05) and body weight (cystatin C: r=0.075, p<0.05; creatinine: r=0.162, P<0.05). Serum cystatin C levels showed no significant difference in sex, but serum creatinine levels were significantly higher in men than women. Serum cystatin C level is suggested to be more useful parameter than serum creatinine level to evaluate early renal impairment.

Dickens의 後期作品에 대한 小考

鄭元夔 群山大學校 1996 論文集 Vol.23 No.-

Dickens became a phoenix of eternal immortality. He is a great novelist, who describes humaneness which all people can reverberate by exciting times and human being with his flowing prose. He tried a reformation by using the weapon of novels and charging with Oliver Twist, he revealed illogicality and injustice of the rule of the poor and asylum of the poor. And charging with Little Dorrit, he laid stress on unfairness and absordity of confinement a debter, and charging with Nicholas Nickleby, he convoked the injustice of education. This paper is to study his characteristic workers, Oliver Twist, Dombey and sons, which are recognized to be very important. But comparing his early workers and latter term workers, they are mostly dark and gloomy in their expression. Especially in the "Bleak House˝ he used much symbol and the readers can find out the result of discredit in it. And ˝Forg Everywhere ˝Suggests the injustice and decay of English court in those days. And in the work, readers can find out that many times and many expense are needed for those days trial of the Gridley event
