We analyzed the non-Newtonian and non-isothermal flow with Carreau-Yasuda viscosity model in co-rotating and counter-rotating twin screw extruder systems. The mixing performances with respect to the screw speed, the screw pitch, and the rotating direction have been investigated. The dynamics of mixing was studied numerically by tracking the motions of particles. The extent of mixing was characterized in terms of the deformation rate, the residence time distribution, and the average strain. The results showed that the high screw speed decreases the residence time but increases the deformation rate. Small screw pitch increases the residence time. It is concluded that the high screw speed increases the dispersive mixing performance, while the small screw pitch increases the distributive mixing performance. Co-rotating screw extruder has the better conveying performance and the distributive mixing performance than counter-rotating screw extruder with the same screw speed and pitch. Co-rotating screw extruder developed faster transport velocity and it is advantageous the flow characteristics to the mixing that transfers polymer melt from one barrel to the other barrel.

The characteristics of NOx emissions in pure hydrogen nonpremixed flames with coaxial air are analyzed numerically for the three model cases of coaxial air flames classified by varying coaxial air velocity and/or fuel velocity. In coaxial air flames, the flame length is reduced by coaxial air and can be represented as a function of the ratio of coaxial air to fuel velocity. Coaxial air decreases flame reaction zone, resulting in reducing flame residence time significantly. Finally, the large reduction of EINOx is achieved by the decrease of the flame residence time. It is found that because coaxial air can break down the flame self-similarity law, appropriate scaling parameters, which are different from those in the simple jet flames, are recommended. In coaxial air flames, the flame residence time based on the flame volume produces better results than that based on a cube of the flame length. And some portion of deviations from the 1/2 scaling law by coaxial air may be due to the violation of the linear relationship between the flame volume and the flame reaction zone.

It is obviously true that the aspects of interior designs in current use have been combined with changing trends and developed and handed down throughout centuries. An examination of respective characteristics of spaces where Korean presidents have lived during their terms of office could get a useful clue by which both traces of Korean modernism and senses of modeling can be perceived. However, there are not enough literatures that can be verified. Therefore, it would be especially meaningful to find out and analyze documents unearthed. The purpose of this study is to consider the expressiveness of interior designs of presidential residence and office which have been combined with changing trends and developed, while classifying respective cases during presidential tenure by periods of Joseon Government general, U. S military administration, the first Republic, the second Republic, the third and the fourth Republic, the fifth Republic, and the sixth Republic, examining relevant literatures, photos, drawings and making on-the-spot survey. The study is also intended to get a better understanding of the aspects and the features of interior designs shown in presidential residences and offices that are not so much made known due to uneasy access to archives and to document the resources buried in oblivion and to consider the historical meanings.

The purpose of this study is to analyze which factors affect safety awareness of foreign workers and international students. In the correlation analysis, individual characteristics related to the safety awareness of foreign workers were nationality, status of stay(visa types), place of work, educational background, and Korean proficiency while international students were relevant with only the types of residence. There were significant differences in the safety awareness of foreign workers in nationality, status of stay(visa types), region of residence, educational background, place of work, and Korean proficiency. However, there was a significant difference only in the types of residence for the international students. In the regression analysis of factors affecting safety awareness, there were significant differences in nationality, status of stay(visa types), place of work, and Korean proficiency in the case of foreign workers. It was analyzed that nationality and status of stay had a negative (-) effect, and the place of work and Korean proficiency had a positive (+) effect. In the case of international students, it was analyzed that only the types of residence had a negative (-) effect on safety awareness.

Prairie style houses in first stages of Frank Lloyd Wright's architecture activity pay a leading role in the process of house modernization as reflecting social and economic circumstances of the time based on traditional house style of the States. Wright's first work after retiring from L. Sullivan's office, Winslow house in 1983 is pioneering work predicting prairie house. This is because this house has only one modern architecture language of Wright and follow no style prevailing of the time. So, a researcher analyse Winslow house within the framework of functional thinking and new formative value creation in the modernization process of western house. Through this, The goal of this study is to find out modern characteristics and the meaning of Winslow house in modernization process prior to the 1900s. Firstly, the followings are modern characteristics of Winslow house. First, Winslow house has original planning breaking from custom based on modern functional and reasonable thoughts, and has practical space reflecting resident's inner demand. Second, Winslow house has modern new plastic value through original exterior breaking from custom and integrated shape of inner-outer space and structure. Secondly, the followings are the meaning of Winslow house in modernization process prior to the 1900s. First, Wright intend to suggest directions of residence modernization through Winslow house before designing Prairie style houses in earnest. Second, mixing of modern vocabulary and eclecticism show a sign of residence modernization process on the time. Third, inner-outer flowing space, opening space concept of Winslow house has innovative meanings predicting spacial characteristics of modern architecture.

입자추적기법(Lagrangian Particle Tracking; LPT)을 적용한 수치모델을 이용하여 조력발전소 운영에 의한 시화호 외측해역에서의 체류시간 변화를 파악하였다. 수치모델의 실험안은 공간적인 분포 특징을 살펴보기 위하여 시화호 외측 해역을 4개 구역으로 나누어 구역별 평균체류시간을 산정하였다. 구역별 평균체류시간은 운영 전과 운영 중 모두 가장 외해에 위치한 지역(약 3일)에서 내만에 위치한 지역(약 13일)으로 진입할수록 증가하는 특징이 나타났다. 구역별 평균체류시간 변화를 운영 전과 운영 중으로 비교하면 운영 전에 비해 운영 중에 가장 외해에 위치한 지역에서는 증가하고 나머지 구역에서는 감소하였다. 조력발전소 운영에 의한 인위적인 배수는 가장 외해에 위치한 지역에서 와동(vortex) 형성으로 입자 정체를 유발하였고, 나머지 지역에서는 연행작용(entrainment)을 발생시켜 체류시간의 변화에 영향을 주었다. 즉, 배수 시 발생하는 제트류(jet flow)와 와동, 연행작용으로 인한 체류시간 변화는 외해와 내만의 수평적 혼합 증가를 보여준다.
