LES(Large eddy simulation) is an intermediate technique between the direct simulation of turbulent flows and the solution of the Reynold-averaged equations. The method is initiated by the introduction of a filtering operation which seperates the large-scale and small scale structures. The large scales are computed explicitly, whereas the small scale necessarily are modeled. In this study, a LES model used three-dimensional incompressible Navier-Stokes equation is calculated for the numerical simulation of turbulent flow in the PBL. Instantaneous and detailed flow of velocity component war obtain with LES and horizontal mean vertical profile of potential temperature was indicated typical profile in the PBL.

藥酒 製造시 솔잎 添加 效果를 調査하기 위하여 솔잎 抽出物 첨가가 S. cerevisiae의 生育에 미치는 影響과, 솔잎분말을 添加한 제국 과정 중의 酵素 活性 및 약주 발효 과정 중 pH, 總酸, 알코올의 含量 變化를 調査하였다. 솔잎의 일반 성분으로는 수분 54.80%, 단백질 8.18%, 조지방 2.07%, 섬유 23.13%, 조회분 1.10%였다. 솔잎 첨가구가 대조구에 비하여 S.cerevisiae의 증식을 억제하는 효과가 있었다. 제국 과정 중의 amylase 활성은 모든 시험구에서 제국 24시간에서 최고의 활성을 나타내었고, 솔잎 2.0%구는 대조구에 비하여 높은 활성을 보였다. 산성 protease 활성은 솔잎 첨가구가 대조구에 비하여 효소활성이 높았으며, 솔잎 분말 2.0% 첨가구는 발효 24시간에서 활성이 가장 높았다. pH는 솔잎의 첨가량이 증가할수록 높았으나 발효기간이 경과할수록 감소하였다. 총산의 변화는 발효기간이 길어질수록 높았고, 0.1, 0.5, 1.0% 솔잎첨가구는 대조구에 비하여 총산의 함량이 높았으며 첨가량이 많아질수록 낮아졌다. 솔잎 분말의 첨가량이 증가할수록 알코올의 함량은 대조구보다 낮았으나, 첨가량에 따른 큰 영향은 나타나지 않았다. The study is to investigate the effects of addition of pine needles's extract on the growth of Saccharomyces cerevisiae and to investigate the changes of α-amylase activity, acid-protease activity, pH, total acidity, alcohol content during alcohol fermentation with variation of the amount of pine needles powder. The composition of pine needles sample were as follows : moisture 54.8%, crude protein 8.18%, crude lipid 2.07%, crude fiber 23.13%, crude ash 1.10%. Treatment groups with pine needles extract have an inhibitory effect on the growth of S. cerevisiae companre to control group. The highest activity of α-amylase was shown at 24 hours fermentation in all treatments and the only treated group with 2.0% addition of pine needles powder had higher amylase activity than that of control group. The activity of acid-protease in the treatments was higher than that of controls and the highest protease activity of 2.0% treated group was shown at 24 hours fermentation. The pH was increased in the adding more pine needles powder but it would be decreased with the lapse of fermentation time. The change of total acidity was increased with the longer fermentation. Although the content of total acidity was higher in 0.1, 0.5 and 1.0% treated groups than that of control group, the small in addition of pine needles powder the less total acid content. Although the alcohol content of treated groups were a little lower than that of control group, there were no different effect on the alcohol content as the additive amount of pine needles powder.

조순호,선성규 광주대학교 산업기술연구소 2002 産業技術硏究 Vol.16 No.-

전편의 실험연구에 이어, 본 논문은 스프링모델을 사용한 합성접합부의 변형해석 모델을 설명하고 있다. 최근 들어 접합부상세에 따른 콘크리트의 구속특성을 고려한 접근방법이 Wight에 의해 제시되어, 이를 조사하였으며, 또한 실험결과와 비교하여 내진성능을 평가하였다. Wight는 변형예측을 위하여 평면응력에 근거한 간단한 해석을 제시하고 있으나, 본 연구의 접합부와는 상이한 구속 및 기하학적 조건을 포함하고 있으므로 구속계수 k_c값의 수정이 요구되었다. 이렇게 하여 예측된 결과는 실험결과와 어느 정도 일치하였다. Further to the companion paper that treats a experimental research carried out as part of this research, various analytical approaches to model the joint deformation based on a series of springs was also examined. Recently, To consider the enhanced characteristics of confined concrete depending on joint details, the procedure and an empirical constant for the enhanced strength suggested by Wight was adopted. The analytical model presented including the joint deformation can be used for the future overall building analyses. Further, modifications for defining the enhanced properties of confined concrete and inclination angles for struts and uniform, stress fields tests are necessary for present tests in predicting the shear versus shear strain response of a joint panel with the Wight's procedure.

조윤정,김성현,이인화,김시욱,고문주,박성규,이범규 조선대학교 환경공해연구소 2000 環境公害硏究 Vol.16 No.1

Leaching and adsorption equilibria of Sr Chemical Species from the near field of a repository has been studied in solidified cement with Fe and oxidized Fe. The absorption percent, Ads %, and distribution coefficient, K_(d) were calculated using equilibrium concentration to predict the extent of leaching and adsorption. In the mixed aqueous solutions the Ads % increase as Cement(C)/Water(W) ratios increase and K_(d) was decreased for Sr. These behaviors were discussed by adsorption and equilibrium of spiked ions. Oxides Fe promoted the adsorption of spiked ions, but pure Fe had no effect. E_(h) values were also estimated and discussed to elucidate oxidation-reduction environment of experimental system.

조규성 안성산업대학교 1998 論文集 Vol.30 No.-

오미자 알코올 추출물을 0.0, 0.01, 0.1, 05 및 1.0%씩 배양액에 첨가하고서, S. cerevisiae의 알코올 발효에 미치는 영향을 조사하였다. 먼저 오미자의 일반성분 조성은 수분 12.33%, 탄수화물 57.72%, 조지방 16.33%, 조단백질 4.42%, 조회분 5.6%, 조섬유 2.53%이였으며, 70% 알코올 추출물 함량은 35.32% 였다. S. cerevisiae의 증식은 전 발효기간 중 0.01%구와 0.1%구가 대조구보다 증가하였고 0.5%구와 1.0%구는 대조구보다 억제되었다. 각 시험구의 alcohol 함량은 발효 72시간의 경우 0.1%구(5.86%)>0.01% 구 (5.75%)>0.0% 구 (5.64%)>0.5%구 (5.50%)>1.0%구 (5.35%) 순으로 생성되어 오미자 추출물의 소량첨가에서는 증량되고 그 이상의 첨가에서 감량되었다. 각 시험구의 유기산 즉, 젖산, 사과산, 초산, 구연산의 함량은 오미자 추출물의 농도가 증가할수록 증가하는 경향을 보였으며, 특히 1.0%구에서 가장 많은 함량을 보였다. The effects of Omija alcohol extract on the alcohol fermentation of S. cerevisiae were investigated. S. cerevisiae was inoculated into sterilized glucose solution medium(added with Omija alcohol extract 0.0, 0.01. 0.1. 0.5, 1.0%, respectively), and they were incubated a 72 hours in each stationary and shaking cultures(temp. 30℃). The proximate compositions of the Omija fruits were moisture 12.33%, crude fat 16.33%, crude protein 4.42%, ash 5.6%, carbohydrate 72.72% and crude fiber 2.53%. The cell growth of S. cerevisiae was more increased in the media containing 0.1, 0.01% Omija alcohol extract than in the control group at 30℃ for whole fermentation. But the growth was inhibited in the medium containing 0.5%, 1.0% Omija alcohol extract. After 72 hours fermentation period, the alcohol content of each treatment groups were 5.68% with the control groups, 5.76% with the 0.01% treatment group, 5.83% with the 0.1% treatment group, 5.59% with the 0.5% treatment group, 5.53% with the 1.0% treatment group. The more the quantity of Omija alcohol extract was added, the more organic acids(lactic acid, malic acid citric acid and acetic acid) were produced by S. cerevisiae at 24 hours fermentation. The contents were increased remarkably in the medium containing 1.0% Omija alcohol extract. Key words : Schizandra chinensis, Omija, alcohol fermentation.

자동차손해배상보장법 제3조상의 운행기인성에 관한 판례연구 : 대법원 2009. 4. 9. 선고 2008다93629판결

조규성 부산대학교 법학연구소 2009 법학연구 Vol.50 No.1

오늘날 자동차는 인간생활에서 없어서는 안 되는 생활필수품이고 그 수도 날이 갈수록 증가하고 있다. 자동차의 이용이 증가할수록 필연적으로 사고를 동반하게 되는데, 그 사고에 대하여 피해자가 가해자의 과실을 입증해야 하는 전통적인 손해배상책임이론으로는 피해자를 제대로 보호할 수가 없다. 자동차손해배상보장법에 의할 때 자동차를 운행하는 자는 '운행 중에 일어난' 모든 사고에 대하여 자배법에 의한 손해배상책임을 지는 것이 아니라 그 중에서 '운행으로 말미암아' 일어난 사고에 대하여서만 그 책임을 진다. 이는 운행과 사고발생 사이에 상당인과관계가 존재하여야만 손해배상책임을 진다는 의미이다. 하지만 최근의 대법원판결들을 살펴보면 자배법의 입법목적인 피해자의 보호를 위한다는 명분하에 '운행기인성'과 관련한 해석을 확대함으로써 자배법 관련 법조문의 형해회(形骸化)를 가져올 우려가 있고 이러한 해석방법은 구체적 타당성을 상실하여 법적 안정성을 해할 우려가 제기되고 있어 운행기인성을 해석함에 있어 합리적 제한이 필요하다고 본다. 자배법의 그 본질적 기능은 어디까지나 운송수단으로서의 '자동차의 운행으로 인한 사고의 피해자'에 대하여 손해배상을 보장하는 것이기 때문에 운행기인성에 대한 무한정한 개념의 확대는 타당하지 않다고 여겨진다. 이번 대상판결 역시 운행기인성에 대한 해석을 지나치게 확대하여 피해자의 보호라는 측면만을 지나치게 고려함으로써 향후·운행 중의 사고'이면 모두 자배법상의 운행자책임을 인정해야한다는 모순된 결론에 이를 수 있는 내용을 담고 있어 파기환송심에서 바로잡아져야 할 것으로 본다. 결론적으로 무분별한 운행기인성의 확대해석은 자배법의 근간을 흔들 수 있는 불합리한 결과를 야기할 수도 있으므로 해석에 있어 신중을 기해야 할 것이고, 그런 의미에서 이번 대상판결은 재고되어야 할 것으로 본다. Automobile has become such an integral and essential part of the daily lives of the modern people that they cannot seem to survive without them. Along with the increase in the usage of automobile, traffic accidents are inevitable. It must be pointed out here that the traditional theory of automobile damage compensation law which states that the victim must prove that a misconduct has been committed by the said culprit is not very sound especially in light of protecting the victim. According to "The Automobile Damage Compensation Law(ADCL)", a man who driving a car is responsible for an accident only "Due to Operation of Automobile" - not for all the accidents widely related to automobile operations. It means there should be Reasonable Causation(appropriate cause and effect) between driving and accident to be responsible. Nevertheless, there is still a problem. Until now, our theory and precedents of the 'Due to operation' has been determined on the meaning of the general causation only, so problem of adequate cause comes down experience and judgement from the facts that much of these problems due to the legal consequence will still remains the problem of interpretation. Eventually the Supreme Court 'an accident due to operation' would decide to stand in a relationship with Reasonable Causation (appropriate cause and effect), if the driver of the car involved a little error, the Supreme Court tend to admit extensive 'Due to operation'. The effort of Supreme Court which the legislative intent of the ADCL meets protection of victims, if possible, the decision to 'Due to operation' are widely recognized. Eventually it will be obvious that the victim will eventually work to its advantage. But look at the recent Supreme Court cases, inclined to admit the range of "due to Operation" widely. So it is possible that article of ADCL will be to destroy. How to interpret the validity of the loss of these specific concerns raised violate the legal stability, so interpretation of 'Due to operation' is needed a reasonable restriction. This Supreme court judgement inclined to admit the range of "due to driving" widely, for the victims are considered excessive in terms of protection. I oppose to the Final Judgement because reach contradictory conclusions to admit liability on ADCL if automobile is operating accident, though it keeps step with the purpose of legislation of ADCL which protects the victim sufficiently. Reckless interpretation of a stretch of "due to driving" is to shake the base of the ADCL, it's interpretation will have to be cautious.
