This study was conducted to determine whether or not the form and angle of the precombustion chamber affected the performance of agricultural diesel engines. Twenty different types of precombustion chambers were designed and tested using a two way classification with four individual tests. The output power and specific fuel consumption ratio at full load were measured and analyzed. The results of the study were summarized as follows; 1. The diameter of main passageway giving the best power output and specific fuel consumption ratio at full load was between 5.8 and 6.1mm. The ratio of area of main passageway bore to that of piston head was from 0.4 to 0.44 percent at the highest engine power. 2. The angle of main passageway giving the best power output and specific fuel consumption ratio at full load was between 41 and 43 degrees. 3. The change of the diameter of main passageway affected the output of engine more significantly than the change of angle, however, on the specific fuel consumption ratio the angle of main passageway had more effect than the diameter.

The objective of this study is to present a new design method at the idea brainstorming process, which requires a great deal of time and effort to seek their own ideas in existing design process and to develop a user support idea forms generation system called OCIGS (Openware Creative Idea Generation System) that makes it possible to create a variety and 3D forms as well as a quantitative evaluation data for the actual types that compose the aesthetic factors and designs of qualitative standards. In order to achieve these objectives : First, overcoming the limitation of 3D form generation ability by establishing visual application system, Second, accepting users' opinions by generating 3D images dynamically, analysing and giving information on the preferred ones on the web on real time, Third, identifying tendency of preference so that they can generate preferred colors and images in future by updating image combination and dropping low-preferred ones. This system would play a role as an idea or form generation application in the actual 3d form design development process.

The purpose of this study is to investigate the correlation between aluminum form work and noise-induced deafness by conducting special health examination on construction aluminum worker and noise measurement at the workplace. All the 11 aluminum form workers were diagnosed with noise-induced deafness after holding a special health examination. The workers have not had any previous history of noise-induced deafness which indicates that aluminum form work is related to noise-induced deafness disease. The impact noise of 120 dB(A)~125 dB(A), which exceeds the regulations of industrial safety and health act, was found during the dismantling rather than installation when noise measurement was made at the aluminum workplace. The aluminum form workers could permanently lose the hearing sense if they are exposed to this impact noise. This study is to suggest the method to prevent noise-induced deafness for aluminum form workers by firstly giving out hearing protection equipment at the construction site and secondly installing rubber mat, soundproof panel as well as changing the noise-lowering technique.

Rapid urbanization has fostered development of modern cities. Although Conventional zoning played its role to control urban development, it also segregated land uses and created homogeneous development pattern. Mega cities with satellite bed towns has not shown their unique identity and characters. In order to develop comprehensive approach which may bring social and physical enhancement can be difficult to achieve by considering city as a two dimensions. On contrary, extensive analysis and proposals require an approach which can perceive city with three dimensions. Form-Based Codes (FBCs) are appeared as an alternative to conventional zoning with different design process and principles. FBCs approach urban place with three dimension and giving priority to form rather than land use. The purpose of this study was to analyze the necessity of FBCs and its concept, components and how this would change urban characteristics in the aspects of architectural design through analysis on 4 case studies for zoning codes of US cities. Through comparison of components in Form-Based Codes of 4 different cases, this study can show the reasons for differences in application of Form-Based Codes and how detailed components would play a role to establish better urban environments.

In 2001, eight small-sized dogs and three medium-sized dogs with or without clinical signs such as vomiting, dyspnea and enlargement of superficial lymph nodes were diagnosed as lymphoma by radiography, ultrasonography and cytology. Among them, six were female mainly over 7 years old and others were male around 4 years old. There were six cases of multicentric form lymphoma, three cases of mediastinal form, an alimentary and an extranodal form, respectively. Radiographic findings were enlarged cranial mediastinal lymph node, sternal lymph node, and tracheobronchial lymph nodes on thorax and hepatomegaly, splenomegaly, and enlarged sublumbar lymph nodes on abdomen. Ultrasonographic findings revealed enlarged abdominal lymph nodes and multifocal hypoechoic lesions on the liver. Especially, severe wall thickness of small bowel was observed in a dog with alimentary lymphoma. Three dogs were dead during chemotherapy, and three dogs were dead without any treatment. Three dogs did not return and two treated dog showed normal status. Radiography and ultrasonography, although not giving an final diagnosis for lymphoma, are useful for assessment and diagnosis of lymphoma.

This study says that giving a life through the mixed power of motions which can not be fixed. It is a fundamental activity of the art of dance. In the fact, the art of dance is defined as the most instinctive and intuitive arts show that dance is a harmony of emotion on the body, thus, this view wants to discuss the relations between "sense and body". This view doesn't focus on the mere motions of dancing form, but characterizes dance as an art of another vitality through the mixture and combination of these motions. In other words, this study emphasizes that dance transcends time and space on stages, and that dance, as an expression of identity, is an art which shows a sense from inside of human. Therefore, when we want to understand the true meaning of the art of dance, we should attend what attributes of dance define it as an art and show its creative. This study, thus, seeing those attributes as the life-giving function of dance, aims to help understand the principle meaning of the art of dance that realizes creation as well as the attitudes of audience who appreciate the art of dance. And by doing so, this study contemplates how we should see the creative idea of choreography, forming sympathy and the art of dance.

The purpose of this research is to investigate the characteristics of Chinese minority women's waistbands, in view of their lifestyle, costume, and symbolism. The research method combined literature research and case study. In the case study, this research targeted the secondary data of a total of 215 pieces from books, articles and the internet. A total of 5 pieces per each representative women's waistband of 43 minorities, excluding those who did not wear a waistband, we collected. We then quantitatively analyzed the form and decoration of the waistbands. As a result of considering the form, the waistbands of Chinese minorities per region were closely related to the costumes, mainly showing high similarity in respect to color and decoration. Moreover, the decorations of the waistbands were most often made from their own area's special products, such as silver, bronze, cotton, and linen, amongst other. The form and decoration of the Chinese minority women's waistbands were all connected with functionality, aesthetic impression, and symbolism, which can be said to be an important part of understanding Chinese minority costume culture. This research contributes to the development and preservation of Chinese minorities' costume culture by considering and analyzing unique costume factors besides giving excellent fashion design ideas for contemporary fashion.

This study analyzes areas, traffic lines and characteristics of block of traditional villages in order to suggest how to build urban village in the way that can solve problems occurring in residential areas these days. The study showed the following results: 1) Traditional villages have definite boundary and entrance, and the community area for the villages is close to the entrance to encourage community activities of villagers. 2) With an access in the form of a blind alley branched from the main road, traditional villages form a small-sized clustering and encourage community activities in a natural way. 3) Formed of block with a pattern of net, blind alley or standing in a line on both sides, traditional villages help residents to form close relations between. These findings suggest that for building desirable urban villages, 1) they should have definite boundary, 2) size and location of community area should be determined in the way to activate community activities of residents, 3) roads inside the village should have branched form rather than standardized check pattern so that small-sized clustering could be formed along the branched inner roads, and 4) clustering in villages should be arranged in a line on both sides or in the form of a blind alley giving consideration to the length and width of roads. The roads should be also of a closed type so that residents could create strong bonds with their neighbors.
