This paper proposes the heuristic algorithm for the generalized GT problems to consider the restrictions which are given the number of machine cell and maximum number of machines in machine cell as well as minimum number of machines in machine cell. This approach is split into two phase. In the first phase, we use the similarity coefficient which proposes and calculates the similarity values about each pair of all machines and sort these values descending order. If we have a machine pair which has the largest similarity coefficient and adheres strictly to the constraint about birds of a different feather (BODF) in a machine cell, then we assign the machine to the machine cell. In the second phase, we assign parts into machine cell with the smallest number of exceptional elements. The results give a machine-part grouping. The proposed algorithm is compared to the Modified p-median model for machine-part grouping.

The hat is the most flexible human head covering. Almost entirely enveloping the hair, it can be simple, pure, elegant and mysterious. Yet it is frequently a highly decorative form of dress. The hat also takes a part in the extension of the area of art as soft-sculpture. My purpose of this thesis is to present diverse artistic hats with natural images by nontraditional materials and natural resources. The reason why I select nature as them is that it is absolutely the origin of life and art. To develop the innovative hat design, I focus on the material to extend the range of art expression. I observe nontraditional materials such as wire, paper and so on that enhance heterogenetic feeling from natural images. The attempt is made to enhance the visual effect by harmonizing the disharmonious feeling. Natural resources such as moss, orange, feather and so on could be adapted to the hat and applied for unique design, which supplies new expression. Therefore, the harmony of natural images and natural resources could avoid dullness, bestow elegance and polish the unique beauty creation of the hat.

닭의 전신장기에 림프종 발생이 특징인 마렉병(Marek's disease; MD)은 림프구성 백혈병(Lymphoid leukosis; LL)과 병리학적 소견이 매우 유사하여 감별이 요구된다. 마렉병 바이러스(Marek's disease virus; MDV)는 질병초기에서 후기에 이르기까지 모낭 상피세포에 세포용해성 감염을 지속적으로 일으킨다. 세포용해 성 감염이 있는 모낭상피세포는 변성내지 괴사되어 있고 핵내봉입체가 관찰된다. 또한 세포용해 성 감염이 있는 모낭상피세포 바로 밑의 진피와 깃털 수질(feather pulp)내의 혈관주위에 림프구 침윤이 관찰된다. 이러한 피부병 변은 MD의 특징적인 병 변들로서 LL과 감별할 수 있는 결정적인 단서이다. 본 고에서는 MD에 관한 전반적인 것과 특히 MD 진단을 위한 피부병 변의 유용 성에 대해서 자세히 논하고자 한다

Moliere completed classical French comedy by combining farce and commedia dell\`arte. Moliere believed that it was a plays obligation to give a lesson and entertainment. Moliere recreated commedia dell\`arte\`s typical acting patterns and characters in his work. He created with Lully comedie ballet that combined ballet and comedie for taste of Louis 14. Les precieuses ridicules critically displayed women at that time. Both contemporary high status women\`s custom and behavior were the targets of the author\`s synical criticism. There are three notable clothing imageries are shown in this work. First, Moliere used a variety of items in order to show emptiness of noble at that time. Items are ribbon and loop decorated rhingrave, feather decorated hat, perfumed wig and glove, lace covered canon and flower decorated shoes. Second, the author showed people\`s stutus through their clothes. Last, the author used clothing used clothing as a metaphor for hypocrisy. Thus when he said “take off the clothes” he meant take off hypocrisy and return truth.

The present study investigated the construction of the moral concepts of 3-, 4-, and 5- year old Korean children. Instruments were the Maternal Behavior Research Instrument by Schaefer for mother and feather nurturing attitudes, and the Domain Distinctiveness Model for children's moral judgments. Maternal and teacher attitudes were categorized by the affection-rejection factor consisting of affection-affection, affection-rejection, rejection-affection, and rejection-rejection dimensions, and by the permissive, -control factor consisting of permissive-permissive, permissive-control, control-permissive, and control-control dimension. Children's data were collected with an individualized interview in which children were asked to judge moral and social conventional transgression events. 30 children were assigned to each of the maternal/teacher attitude dimensions; thus, there were 120 children for each factor. Results showed that (1) the affection-affection cohort was must strongly related to moral rules using both the seriousness criterion and deserved punishment criterion, and (2) the permissive-permissive cohort was most strongly related to reasoning and action. However, this cohort did not break out of children's structural limitation (limited responses to the intangible).

도축 부산물인 우모는 높은 영양적 가치를 가짐에도 불구하고 현재 사용하는 물리화학적 처리법의 여러 단점으로 효율적으로 이용되지 못하고 있어서 경제적 방법인 생물 공학적 처리에 대한 연구의 필요성이 커지고 있다. 본 연구에서는 그러한 방법 중 대표적인 방법으로 미생물이 생산하는 keratinase 를 이용한 생분해에 대해 연구를 하기 위해 퇴비화 볏짚에서 keratinolytic protease 생성능이 우수한 균주를 분리하였고 생화학적 동정법과 16S rDNA를 이용한 동정결과 B. pumilus로 동정되었다 본 실험에서 분리된 B. pumilus는 기존에 활발히 연구되어 있지 않는 균주로서 native feather 분해도가 기존에 알려진 Bacillus 속들이 3일 정도에서 분해가 완료되는 것과는 달리 36시간$\sim$48시간 내에 깃대까지 완전히 분해하였다.

This paper describes the characteristic feather of propulsion system adopting mass production. The train formation is composed of 4 cars by 2 Motor cars and 2 Train cars. Acceleration rate must be 3.0 km/h/s or more when the car starts up to 35km/h by 16ton of passenger load. The system information supervision is easy because the system is controlled to perfect digital circuits, all information of an action is stored in a memory and is managed. The control system is composed of a fully digital circuit and a high level software such as C language. The DSP TMS320C31 is used for main processor and has the capability of 50MHz, 32bit floating point operation and has a C compiler. Therefore, the implementation of control algorithm and the change of function are easy. VVVF inverter using IGBT conducted variable combined test, environment test using chamber, interface test and field test etc.

We have developed a nanoparticle focusing mask which can generate particle arrays directly on the large area with high resolution. Using this mask, nanomaterials are precisely deposited onto desired positions on a substrate surface. We obtained various sizes of arrays ranging from 80 nm to 6 ${\mu}m$ with silver and copper nanoparticles that are generated by a spark discharge and an evaporation-condensation method. The feather size is much smaller than that of mask openings due to the focusing effects, like electrostatic lens, caused by charge or electric potential on insulator mask surface, which also prevent a mask clogging. The particle array size depends on the size of mask open patterns and focusing effects near the mask relate to ion flow rate and electric potential. We have demonstrated that diverse size of arrays with high resolution could be obtained repeatedly using the same sized mask in atmosphere.
