This study is analyzing a member kind after placing concrete, the location-based temperature record, and the strength development, by making insulation gang-form with application of polyurethane form to general gang-form for securing efficient concrete quality in the condition of cold weather. According to our experimental results, the member of general gang-form with curing in the same condition as the actual field didn’t drop to under 3˚C until before 24 hours in the early part, but fell to under 0˚c from 36 hours later because a large rise in temperature caused by hydration reaction didn't occur. On the other hand, in case of insulation gang-form, the temperature on the surface and the central part didn't go down to under 3˚C before 12 hours in the early part and didn't fall to under it even until 72 hours after it while the peak temperature went up to 12˚C. Thus, it could be known to definitely have excellent insulation effect compared to space heating curing, which is generally performed on the spot. In comparison with space heating curing whose error in curing temperature is big every field, it is judged to likely have great effect on improvement in concrete quality given the work construction in cold weather and on early demolding in a cast during winter.

To evaluate the performance of a new automated coliform enumeration system (TEMPO® CC) for the quantitative test of coliform bacteria contaminated in domestic livestock processed foods, a total of 507 samples of livestock foods were tested by the TEMPO® CC method, the most probable number (MPN) method, and Petrifilm method, respectively. The results of those three methods were compared to each other. Of 507 samples of livestock processed foods used in this study, 217 samples were contaminated artificially with coliform bacteria and the rest (n=290) were contaminated naturally. The results of the TEMPO® CC method for all samples were equivalent to those obtained from the MPN method, except 8 samples. In addition, 496 (97.8%) out of 507 samples made agreement between the TEMPO® CC method and the Petrifilm method. The correlation coefficients between TEMPO® CC and MPN methods as well as between TEMPO® CC method and Petrifilm method were above 0.9, and the slope and intercept of the linear regression model was different in less than 1 value. In conclusion, there were statistically equivalent levels of performance between the TEMPO® CC and the reference and alternative methods for the enumeration of coliform bacteria in livestock processed foods in this study.

In case of general concrete, autogenous shrinkage is about 10% of the drying shrinkage. Therefore it was not considered significant to be a subject matter about managing the crack control and design. It was reported that cracks can be generated from the autogenous shrinkage. Because of the low W/B rate and the high unit binder of the high strength concrete. In this study, autogenous shrinkage and drying shrinkage are examined which is the main reason of the cracks of the high strength concrete based on the previous studies. Comparing the data from this study and previous studies, we developed the shrinkage reduced concrete using shrinkage reducing agent. The purpose of this study is to provide the data for reducing and managing the column shortening of the high strength concrete structures.

Poisson model and Gamma-Poisson model are popularly used to analyze statistical behavior from defective data. The methods are based on binary criteria, that is, good or failure. However, manufacturing industries prefer polytomous criteria for classifying

This paper describes an investigation of an outbreak of foot-and-mouth disease (FMD) in Republic of Korea in January 2010. In this paper, we investigated introduction to the index farm from overseas countries, transmission from index farm to other outbreak farms. The introduction factors were divided direct, indirect factors or airborne spread factor. Based on the epidemiological data, clinical information and other data, in these introduction factors, it was likely that outbreak of FMD in index farm was due to international goods or employees from overseas countries (including China). There were other suggested causes in index farm. But it was less likely that outbreak of FMD in index farm have occurred by other causes. The transmission factors from index farm to other farms were also divided direct, indirect factors or airborne spread factor. In these transmission factors it was possible to make assumptions from index farm to other outbreak farms that the FMD virus was transmitted through animal treatment, persons concerned and persons (who were) attended farmers’ assembly.

소수성 고무상 고분자 PDMS에 NaYzeolite 함량을 1~40 wt%로 달리하여 PDMS-NaYzeolite 복합막을 제조하였다. 그리고 FT-IR, 1H-NMR, SEM에 의해서 막의 특성을 조사하였다. 복합막의 NaYzeolite 함량 변화에 따라 H2와 N2의 투과도와 선택도를 조사하였다. PDMS 단일막은 기체투과 압력이 증가하면 H2와 N2의 투과도와 선택도(H2/N2)가 증가하였다. PDMS-NaYzeolite 복합막의 H2와 N2 투과도는 NaYzeolite 함량 0~10 wt%까지는 증가하고 그 이후부터는 감소하였고, 선택도(H2/N2)는 0~2 wt%까지는 감소하고 그 이상에서는 증가하였다. PDMS-NaYzeolite 복합막은 H2 투과도가 증가하면 선택도(H2/N2)는 0~2 wt%와 10~40 wt% NaYzeolite 함량 범위에서는 감소하고, 2~10 wt% NaYzeolite 함량 범위에서는 증가하였다.

The malodor as the sense pollutions is rising to surface with a new environmental matter. Especially, malodor"s appeal is increasing steadily from a residential area of the industrial complex. The odor characteristic and odor active compounds of industries should be identified to solve this problem. The dye company was selected as a sample among the industries. Air samples of the dye company were sampled with polyester aluminum bag and it was analyzed by GC/FID/O and GC/MS. The feature of the complex odor was ironing, sour and burnt smell.

In this study, the most effective salting-out effect has been examined in terms of application of various inorganic salts (NaCl, Na₂S0₄, NaHSO₃) using Alkali impregnated filter-Headspace-GC/FID. Five various VFAs (propionic acid (99.5%), r-butyric acid (99%), butyric acid (99%), i-valerie acid (99%), valerie acid (99%)) have been used. VFAs have been analyzed by adding 30%, 70%, 100%, 150%, 200% of different inorganic salts with HS-GC/FID. The efficiency of salting-out effect was obtained from the values of peak area in chromatogram. The most effective salting-out effect for applired inorganic salts was observed at 100% saturation. It was confirmed NaHSO₃ for salting-out effect was the best among inorganic salts. In addition, NaHSO₃ showed more efficiency of salting-out effect than NaCl as molecular weight of VFAs increases.

In this study, simple preprocessing method for the analysis of headspace phase has been examined. The odor causing components were verified from the analysis of amine species emitted from squid waste. The concentrations of odor causing chemical components were confirmed in terms of four different sample treatments (treatment at 60℃, sonification, pressure treatment, addition of microorganism). HS-autosampler/GC/FID has been used for the analysis of chemical components and standard material addition method was utilized for quantification. The analysis results indicated that the major odor causing amine compounds emitted from squid waste were DMA and TMA. In addition, it was confirmed TMA showing higher malodor concentration predicted was relative malodor causing chemical component. Sonification and pressure treatment reduced the production of DMA and TMA by lowering the activity of microorganisms, while the addition of microbial accelerated the metabolism of microorganisms leading to the increased production of DMA and TMA.

A successful fire risk assessment is depends on identification of risk, the analytical process of potential risk, on estimation of likelihood and the width and depth of consequence. Take the influence on enterprise into consideration, Fire risk assessment could carry out along the evaluation of the risk importance, the risk level and the risk acceptance. A large part of the limitation of choosing the risk assessment techniques impose restrictions on expense and time. If it is unnecessary high level risk assessment or Probabilistic Risk Assessment of buildings, in compliance with the Relative Ranking Method, Fire risk indexing and assessing is possible. As working-level technique, AHP method is useful with practical technique.

본고는 조선시대의 야사·야담류를 중심으로 문헌 자료에 그려진 포은상을 개관하는 것을 목적으로 한다. 특히 오늘날 정립된 포은상과는 다른 내용을 전하는 문헌자료의 소개를 통해 포은상의 변천에 대한 이해를 구하고자 하였다. 구체적으로 탄생에 대해서는 우리에게 잘 알려진『고려사』열전과 함께 유교적 가치관에 반감을 가지는 계층 출신에 의해서 쓰여진 『鶏鴨漫録』에 나타난 마주공과 관련된 악의적인 음담패설을 소개해 보았다. 학문문재에 대해서는 포은에 대한 긍정일변도의 사료뿐만 아니라 그러한 포은상이 정립되기 이전의 성현, 서거정, 이제신등의 포은에 대한 평가를 소개하면서 포은상의 변천에 대한 여러 자료를 소개해 보았다. 사람됨, 순절과 관련해서 단심가 등에 대해서도 다양한 자료들을 소개하면서 오늘날 알려져 있는 포은상과는 다른 포은에 대한 몇몇 사실을 소개해 보았다. 그러나 인용 자료를 봐도 알 수 있듯이, 야사나 수필·시화 등에서도 전기적 성격이 강한 자료가 많아 야담과 같은 설화집에는 그다지 보이지 않는다. 『青邱野談』에는 포은이 등장하는 작품이 있지만, 그것은 이인으로서의 캐릭터가 부여되고 있는 것뿐이며, 포은의 생애와는 어떤 관계도 가지지 않는다. 아마도, 포은과 같이 극히 한정된 성격만이 부여된 인물은, 설화의 세계에서 다채로운 인물 조형을 가지기 어려웠기 때문일 것이다.
