본 논문은 국내 외 PV 통합 프로젝트를 구조 디자인의 시각에서 평가한 논문이다. 국내 외 대표사례를 공공시설과 전시시설로 구분하여 국내 사례 3가지, 해외사례 3가지의 대표 사례를 들었다. 평가항목은 건축물과의 자연스러운 통합, 엔지니어링디테일, 혁신적인 새로운 설계의 항목으로 평가하고 그 결과를 비교 분석하였다. 국내의 공공시설 및 전시시설은 주로 옥상층에 독립지지방식을 사용한 사례가 많았으며 아직 디자인적 통합부분에서는 미흡함을 알 수 있었다. 하지만 전시시설은 건축물 설계단계에서부터 PV 패널을 염두에 둔 사례들이 증가하고 있었다. 그에 비해 해외 공공시설 및 전시시설의 경우는 주로 모듈 접합방식을 사용하면서 구조적인 통합과 디자인적 통합을 동시에 이루었으며 사용하는 PV패널의 종류도 좀 더 다양함을 알 수 있었다.

DNA-based technology are about to revolutionize the analysis of population structures as well as the determination of individual indentities. Furthermore, the analysis of polymorphic DNA regions make it possible to reach detailed conclusions on family relationships of individual. Microsatellite loci are increasingly used in population genetic and evolutionary studies. Simple sequence repeats (SSRs) or microsatellites consisted of short tandem repeats (usually 1-6 nucleotide) have shown advantages over other markers. We report here the isolation and characterization of nine highly polymerphic microsatellite loci for phylogenetic and population genetic use in silkworm. Comparative analysis of diverse silkworm strains with microsatellite locus revealed several alleles and discriminative heterozygosity values. A list of primer sequences that tag each locus is provided. The usefulness of microsatellite markers can be expected to enhance the classification in silkworm.

It is a fact that domestic performance art has been sharply progressed but it is focused on only performance quality technique, not on safety of performers and the audience. It is a pity that people's effort to keep safe stage environment have not traced to innovative change, eventually leading to be forced to perform under hazardous condition. This study is to find out and identify that domestic regulation and accident cases are investigated and compared with cases of advanced countries, to verify that performer and the audience are main elements to develop performance art. And it is to show more effective safety measure after pointing out hazardous elements. Research change is limited to review only performance ones of all cultural facilities and to review accident cases from these places to show reasonable safety measures for stage facilities. Operation manager covers almost all of areas such as devices, management, despite a fact that they take charge of stage facilities, illumination, sounds, already. Some conclusions are as follows; 1) performance theatre-related regulations should be established again. domestic safety standards for performance theatre safety should be established. 2) characteristic and purpose of performance place should be clarified at the stage planning and design of them 3) operation expert performance place is required to be trained to cover emergency situation at any time.

In this study, consumer acceptance and sensory intensity evaluations were performed on sponge cakes prepared with domestic and imported cake flours. Specific volume data as well as cross-sectional photograph observations confirmed that the imported flour sample group had greater volume than the domestic flour groups. The imported flour sample group also had a significantly (p<0.05) higher mean overall acceptability score at 5.82; however, it was not significantly different from the domestic white flour sample group (5.40). There was no significant difference in overall texture acceptance between samples prepared with imported and domestic white flours; however, their scores were significantly higher than that of the domestic whole flour group (p<0.05). Consumer acceptances of color significantly decreased as the orders of cake group prepared using the imported, domestic white, and domestic whole flours with the values of 6.48, 5.72 and 4.61, respectively (p<0.05). Acceptance of the air cell and the acceptance and intensity of sweetness did not show significant differences between the imported and domestic white flour group.

We compared colony development and survival rate after artificial hibernation between the bumblebees, Bombus terrestris, produced from domestic and foreign companies. The number of worker and queen produced from foundation colony of three domestic and one foreign companies was 232.4-270.8 and 62.0-181.8, respectively, but there was no statistical difference. in colony development of B. terrestris queens which were terminated diapause by CO₂ narcosis at different companies, oviposition rate, colony foundation and progeny-queen production of bumblebees produced from domestic companies were superior to those from foreign company. But foreign company in the number of worker and queen was superior to domestic companies. On the other hand, survival rate and colony development of B. terrestris queens, which were terminated diapause by artificial hibernation at three domestic and two foreign companies, were no significant differences. These results indicate that oviposition, colony foundation, progeny-queen production, and survival rate after artificial hibernation showed no differences between the bumblebees produced from domestic and foreign companies.

With the development of the Korean economy, the number of arson fire has been radically increased and become a huge problem and issue in Korea Society for last several decades.

Physicochemical and sensory properties of sponge cakes using 2 kinds of domestic wheat flour(white flour, whole wheat flour) and imported cake flour were investigated. In the proximate analysis, white flour had higher contents of water and protein compared with those of imported flour. Whole wheat flour had the highest contents of protein, lipid and ash. Regarding the batter, imported flour sample showed lower specific gravity and higher viscosity than those of domestic flour sample, implying that there was more air incorporation and higher batter stability. As a result, imported flour batter produced larger cake compared to that of domestic flour batter. But indexes of symmetry and uniformity showed no significant difference among the samples. In textural analysis using rheometer, cakes with imported flour were softer compared with that with domestic flour. In gumminess and brittleness, cakes with domestic white flour showed the highest value while that with the imported flour showed the lowest value. For the color measurements of cake crumb, no significant difference in DE was found among the samples. Regarding the cross-sections of the cake observed using SEM, imported flour produced cake with smaller and more even air cells compared to that with the domestic flour cake. In sensory evaluation, cakes with the domestic white flour showed the highest moistness value. But there was no significant difference in springiness, firmness, adhesiveness and ease of swallow among the samples. In conclusion, cakes with domestic white flour and whole wheat flour were as good as that with imported cake flour for the sponge cake preparation.

A technological trend of treating or preventing the cardiovascular diseases has reviewed on 381 domestic and foreign patents from the year 1980 to June, 2007. Primarily focused upon countries such as Korea, Japan and the United States; the leading nations concerning cardiovascular disease, this paper delved into a systematic research of the cardiovascular disease utilizing research focused database and research analysts. Korea was showing increased development in the diet and cardiovascular related areas as shown by increase in related patent caseloads and submission since the 2000. Especially within the area of food production, there had been an increase of market share by up to 50% and the frequency of patent submission had also increased. Japan was showing similar trend as Korea with its increase in research, but the only difference was that Japan was focused more upon medical supplies. With the United States, there was no real consistency with the number of patents, therefore harder to make an accurate assessment.
