In this study, the optimal level of CER issuance price in the energy industry was estimated using a real options considering the uncertainty of emission price. As a result of the analysis, the break-even point for CDM projects in the energy industry registered by UNFCCC from December 2012 to the end of 2021 was 0.64-36.69 euros per ton of CO2 for each individual project. More closely, the emission permit price that reaches the break-even point when NPVw/o CER+ NPVCER ≥ 0 is estimated to be 12.10 euros on average, and the emission permit price that reaches the break-even point when NPVw/o CER + NPVCER ≥ option value is estimated to be 12.63 euros on average. Meanwhile, the option value using real options to reduce business uncertainty is about 19% at the 1-5 euro per ton level, about 11% at the 5-10 euro per ton level, and about 5% at the 10-15 euro per ton level. It was analyzed that there was an effect of increasing emissions prices due to uncertainty reduction. The results of this study may be useful to greenhouse gas reduction project entities, including investors, project operators, and companies with potential mandatory reductions.

Stress-susceptible pigs have been known as the porcine stress syndrome (PSS), swine PSS, also known as malignant hyperthermia (MH), is characterized as sudden death and production of poor meat quality such as PSE (pale, soft and exudative) meat after slaughtering. PSS and PSE meat cause major economic losses in the pig industry. A point mutation in the gene coding for the ryanodine receptor (RYR1) in porcine skeletal muscle, also known calcium (Ca$^{2+}$) release channel, has been associated with swine PSS and halothane sensitivity. We used the PCR-RFLP(restriction fragment length polymorphism) and PCR-SSCP (single strand conformation polymorphism) methods to detect the PSS gene mutation (C1843T) in the RYR1 gene and to estimate genotype frequencies of PSS gene in Korean pig breed populations. In PCR-RFLP and SSCP analyses, three genotypes of homozygous normal (N/M), heterozygous carrier (N/n) and homozygous recessive mutant (n/n) were detected using agarose or polyacrylamide gel electrophoresis, respectively. The proportions of normal, carrier and PSS pigs were 57.1, 35.7 and 7.1％ for Landrace, 82.5, 15.8 and 1.7％ far L. Yorkshire, 95.2, 4.8 and 0.0％ for Duroc and 72.0, 22.7 and 5.3％ for Crossbreed. Consequently, DNA-based diagnosis for the identification of stress-susceptible pigs of PSS and pigs producing PSE meat is a powerful technique. Especially, PCR-SSCP method may be useful as a rapid, sensitive and inexpensive test for the large-scale screening of PSS genotypes and pigs with PSE meat in the pork industry.y.

The purpose of this study is to empirically examine the causal relationship of CSR activities, customer trust and CCID, customer behavior intention(B.I) in the relationship between CSR activities and customer behavior intention(B.I) in the insurance industry, thereby enable top management of insurance company to take it in their consideration that CSR activity help link to customer behavioral intention by customer trust in them and CCID. To achieve the purpose of the study, the hypothesis was established based on preceding research and theoretical background regarding CSR, trust, CCID, behavioral intention(B.I). And this study conducted AMOS statistical analysis based on effective 526 survey data collected from insurance customers across country through online research company. The result of this empirical study is as follows. First, insurance company's CSR activity has a positive impact on customer's trust and CCID, but it did not have a direct significant effect on the customer's behavioral intention(B.I). Second, both customer's trust and CCID have a positive and significant effect on customer's behavioral intention. Third, we have also found that both Trust and CCID played a mediating role between CSR activity and B,I. Fourth, it was found that authenticity did not moderate the enfluence relationship between CSR activity and Trust, CCID. The result of this study shows that insurance company's active CSR activity increase customer trust, thereby create a sense of unity between the customer and the company, In addition, it shows that when CSR activities are mediated by customer trust and CCID, it could lead to customer behavioral intention(B.I) such as repurchasing and positive word-of-mouth activities. to others. The result of this study will contribute to the future research on CSR literature and the marketing strategy of insurance companies.

장내 균총 개선을 위하여 조합시킨 prebiotics와 probiotics는 최고의 건강 증진을 제공할 잠재성을 갖지만, 알맞은 균주선발이 필수적이다. 기능성 식품시장은 연간 15∼20% 성장하고 있고, 그 산업은 33백만 달러의 값어치가 있다(Hilliam, 2000). 기능성 식품은 nutraceuticals, designer foods, medicinal foods, therapeutic foods,superfoods, foodiceuticals와 medifoods로 알려져 있고 그 정의는 전통적인 영양소개념을 넘어선 건강증진 성분을 함유한 식품이라고 할 수 있다(Berner와 O'Donnell,1998). 식품은 phytochemicals, bioactive peptides, $\omega$-3 불포화 지방산, 그리고probiotics 또는 기능성을 갖게 되는 prebiotics의 부가에 의하여 변형될 수 있다(Berner와 O'Donnell, 1998)(표 1). 장관에서 살수 없는 균을 함유한 요구르트의 경우와 같은 다양한 발효 낙농식품 제조에 젖산균을 사용한 이래, 오늘날에는 발효식품에Lactobacillus acidophilus와 bifidobacteria 같은 probiotic 균을 사용하는 경향이다. Probiotic 식품은 살아 있는 미생물을 함유한 식품이고, 그 미생물은 충분한 양이살아 있는 상태로 장 속에 공급되었을 때에 미생물 균총을 개선하여 소비자 건강을 증진시키는 것이라고 할 수 있다(Fuller, 1992). 전통적으로, probiotics는 요구르트와 기타 발효식품에 사용되어 왔지만, 최근에는 드링크, 알약형, 캡슐형, 동결건조물과 같은 형태로도 공급되고 있다. 오늘날, 전세계에 sour cream, buttermilk, 요구르트, 분유와 frozen desserts 같은 식품에 bifidus acidophilus를 함유한 제품이 70개를 넘고 있으며, 일본에서만도 probiotic 미생물을 함유한 형태의 우유제품이 53종류 이상 개발되어 있다. Probiotics는 유럽에서도 매우 인기가 있지만, 주로 요구르트에 한정되어 사용되고 있다(Hilliam, 2000).

The goal of this research was to build comprehensive and systematic basic materials related to IT industry and spatial design. In this research, the trend in spatial design research and its categories are identified and analyzed. The research results show that spatial design researches related to web have declined for last five years. However, a new possibility appears to be latent. An attempt to build database of diverse design information has led to increase in fusion of spatial design education and IT technology from design perspective. Futhermore, residents of space are becoming more active, starting from spatial design to management. Finally, from th environmental perspective, researches on predicting and managing buildings are also growing. Accordingly, diverse researches and financial support for grafting creative education, design process, environment-friendly IT technology and spatial design are needed.

The flash point is one of the most important combustible properties used to determine the potential for fire and explosion hazards of industrial material. An accurate knowledge of the flash point is important in developing appropriate preventive and control measures in industrial fire protection. The flash points for the n-butanol+n-propionic acid and n-propanol+n-propionic acid systems were measured by using Tag open-cup apparatus(ASTM D 1310-86). The experimental data were compared with the values calculated by the laws of Raoult and van Laar equation. The calculated values based on the van Laar equation were found to be better than those based on the Raoult's law.
