In the present study we examine physical characteristics of a thin and rigid magnetic flux tube with a steady flow inside, which is embedded vertically upward in the solar atmosphere. We found from this study that (1) The downward material flow gives rise to a dominant heating in the flux tube which works with the conductive heating in the same direction. However, the upflow flow creates a dominant cooling which works against the conductive heating, resulting in a steeper temperature gradient with a shallower transition region. (2) Since the thickness of the transition region determines the material content in the transition region, a broader transition region of the downflow tube produces a larger differential measure.

In the present work we introduce a new flare activity indicator, MAD and examine its characteristics by analyzing a set of successive three days' observations of a typical active region, AR2372. The computed MAD is compared with conventional activity indicator such as separator. It is found that. (1) MAD traces very well the separator, (2) it. singles out. local discontinuity of magnetic field lines and (3) it. is a good measure of describing the evolutionary status of active region.

Based on the database of 128 disk galaxies (66 SO, 62 S and Irr) mailnly compiled from Kent and Gunn (1982) and Doi et a1.(1995) which is complete down to m < 15.6 mag within a radius of 3°, the orientation of spin vectors of disk galaxies of the Coma cluster has been analyzed. The results confirm the morphological dependence of the orientation of disk galaxies found from the analsis of the Virgo cluster. Common features of orientation of disk galaxies of both clusters are outlined.

쇠파리의 실내 대량사육을 위한 시험에서 산란전기간을 단축 시킴으로써 사충율을 저하시키며 누대사육에 의한 위소현상을 조사하기 위해 각 세대별 용중량의 차이를 조사 하였으며 쇠파리는 성충기 이외에는 자웅구별이 불가능하므로 용중량에 의한 성구별을 시도한 결과는 다음과 같다. 1) 유충 media로부터 용을 분리할 때 사용하는 물을 약 로 가온하여 용을 채취한 결과 산란전기간이 8일로 단축되었다. 2) 누대사육에 의한 세대별 위소현상 조사에서 명세대별 용중량차이에는 유의성이 없었으며 사육온도에 따라서 많은 차이를 보였다. 3) 용중량의 차이에 의한 성구별은 약 의 웅충구별이 가능하였다

1) 쇠파리의 누대 실내사육을 위한 온도는 약 가 좋으며, 이때 유충기간은 약 6.8일, 용기간은 5.3일, 산란전기간은 10.4일, 성충의 수명은 약 30일이었다. 2) 인공사육에 있어서 용화율은 우화율은 였으며 성비는 1 : 1이었다. 3) 용의 체중량은 약 14.5mg이었으며, Wheat bran medium 보다 Standard medium이 사육성적이 좋았다. 4) medium 125gr에 대한 난의 접종수는 약 310개가 가장 적합하였다. 5) rectangular cage를 사용할 경우, 성충의 resting place는 가 적합할 것으로 본다.

This study aims to improve knowledge of consumers’ decision-making by testing a conceptual model that considers the hotel’s service quality and service value toward customers’ behavioral intentions using a mediator, which is the role of consumers’ satisfaction. The object of this research is five-star hotels, which has become a significant segment of the general hotel industry and is undergoing rapid expansion. This research is a quantitative research using questionnaire as the sampling method answered by people who have stayed at five-star hotels before. The total of 150 valid respondents were used in this study. The collected data was processed by a statistical tool software, Partial Least Square (PLS). The major findings of this research showed that the relations between service quality and service value of five-star hotels do not have significant positive impact on consumers’ behavioral intention, nonetheless the mediation analysis shows that customers’ satisfaction partially mediates service quality and service value with consumers’ behavioral intentions to stay. It means that in this case, consumers’ satisfaction has an important role to mediate service value quality and service value. As a result, the study shows that four out of six hypotheses are supported. A couple of recommendations are suggested for further research.
