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.

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%.

In this Study, I wanted to examine that the tonal opposition and neutralization of the dialect of North Gyeongsang province can be applied in Tokyo dialect They say that Tokyo dialect has a similar sentential prosody with the dialect of North Gyeongsang province It is very important to know that some special phenomena are found m the application of tonal rules in these two dialects. The tonal opposition and neutralization govern the sentential prosody of two dialects According to this, there are some tonal rules which are applied in derivation of surface forms from underlying forms First, the following rules are applied in the dialect of North Gyeongsang province a H₂L^n → [L₁HL^n]/ #_# b L₂→ [HHL_0]/ #_# c L·₂→ [H HL_0]/#_# Next the following rules are applied to make tonal noun phrases in Tokyo dialect. a /L₂/ ~ [LH₁]/ #_# b /L_nH/ ~ [LH^n-1H]/ #_# c /L_nH₂/ ~ [LH^n-lHL₁]/ #_# d /H₂/ ~ [HL₁]/ #_#

The influences on water quality of each river by effluents from environmental facilities located in 14 unit watersheds of North- and South-Han River, and Gyungan-cheon were analyzed. Also, the water quality modeling for study area was carried out to analyze the improvement effect of water quality by the strengthening of T-P effluent standard of environmental facilities. For the calibration and verification of model, water quality data and effluent loading calculated for 2006 were used. Data of low water period were used for calibration, and normal water period for verification. The results of calibration and verification were well matched with the real water quality dataset of revers. Also, the validity of the results were estimated using RI(Reliability Index) method. When the T-P effluent standards for environmental facilities were strengthened, T-P concentrations were predicted to improve from 0.025㎎/ℓ to 0.023㎎/ℓ in the outlet location of North-Han River, from 0.056㎎/ℓ to 0.040㎎/ℓ for South-Han River, and from 0.233㎎/ℓ to 0.146㎎/ℓ for Gyungan-cheon. Also, the T-P concentrations of tributaries including Jojong-cheon, Dal-cheong, Sumgang, Chungmi-cheon, Bokha-cheon, Heuk-cheon, and Wonju-cheon were predicted to improve from 0.063㎎/ℓ to 0.010㎎/ℓ, from 0.091㎎/ℓ to 0.053㎎/ℓ, from 0.199㎎/ℓ to 0.100㎎/ℓ, from 0.168㎎/ℓ to 0.148㎎/ℓ, from 0.186㎎/ℓ to 0.105㎎/ℓ, from 0.019㎎/ℓ to 0.013㎎/ℓ, and from 0.822㎎/ℓ to 0.236㎎/ℓ, respectively.

At the first stage, ginseng wine contained 17% alcohol was producted at the 11th day. And through the second stage, acetic acid fermentation ginseng vinegar of which total acidity is 5.8% were produced. In comparison with commercial vinegars for physicochemical quality, acidity of ginseng vinegar was lower than those of commercial vinegars and ph was higher than those of commercial vinegars. The major free sugar compositions in ginseng vinegar were fructose, maltose, sucrose and glucose and in commercial vinegar were fructose, sucrose and maltose. The major organic acid compositions were acetic acid, tartaric acid, propionic acid, lactic acid, malic acid and succinic acid and in commercial vinegar were oxalic acid, citric acid, malic acid and acetic acid.

Air void systems in hardened concrete has an important influence on concrete durability such as freeze-thaw resistance, water permeability, surface scaling resistance. Linear traverse method and point count method described at ASTM are the routine analysis of the air void system that have been widely used to estimate the spacing factor in hardened concrete. Recently, many concretes often have a spacing factor higher than the generally accepted 200-250㎛ limit for the usual range of air contents. This study is proposed to estimate the plane spacing factor by calculation of simplicity. The plane spacing factor need two parameters that are air content and numbers of air voids in the hardened concrete. Those obtained from the standard air-void system analysis of the ASTM C 457. The equation is valid for all values of paste-to-air ratio because the estimation of paste content is unnecessary at the using ASTM C 457. The plane spacing factor yields a similar estimate of the standard spacing factor.
