In case of the design method, which is used in the inside and outside of the country, on corrugated multi plate structures, section modulus would be determined by assuming 2-dementioanl equivalent section of those structures. However, it is impossible to consider 3-dimentional effects when 2-dimentional design method is applied since structures are reinforced with a pattern of the 1200, 1600 mm reinforcements except the 800 mm reinforcement. Thus, in this study, technical specification standard is analyzed for the existing corrugated multi plate design methods, and section strengths, moments, and so on of equivalent and practical sections are compared and estimated using 3-dimentional FEM (finite element method) for semicircles and architectural features widely used. Based on the results of that analysis, analytical basis for 3-dimentional design of the CBS-RIB is suggested.

The purpose of the present study was to identify the effect of ritual dress on korean catholic priest's impression. The subject consisted of 415 undergraduated students. The experimental materials developed for this study were 3 type color photographs stimuli of catholic priest model and 7-point sementic differential scale composed of 49 bipolar adjectives representing personal traits. The data were analyzed by factor analysis. the major findings drawn from this study were as follows : Four factors emerged to account for the dimentional structure of the impression of each dress style. Four factors were titled as open-hearted mind symbolic meaning nature of priest potency. The open-hearted mind factor was the largest throughout the 3types ritual dress. Casula had a positive effect on open-hearted mind nature of prist and negative on symbolic meaning potency. Sutan had a positive effect on open-hearted mind potency nature of priest and negative on symbolic meaning. Black suit with roman collar had a positive effect on open-hearted mind symbolic meaning nature of prist and negative on potency, Therefore the ritual dress had significant effect on korean catholic priest' impressin of open-hearted mind symbolic meaning nature of prist activity and potency

The purpose of this study was to identify the effect of religious habits and hair styles on korean catholic sister's impression. The subject consisted of 256 female high school students and 256 female undergraduated students The experimental materials developed for this study were 16 color photographs stimuli of drawing and 7-point semantic differential scale composed of 30 bipolar adjectives representing personal traits. The major findings drawn from this study were as follows: 1) Four factors emerged to account for the dimentional structure of the impression of the Korean catholic sister's in religious habits. Four factors involved purity, formality, potency, appearance. 2) The clothing types and hair styles had significant effect on purity, formality, potency, appearance. The clothing types had an effect on purity, formality and potency while the hair styles affected formality. 3) Perceiver's age influenced impressions formed by clothing and hair styles. Female high school students were affected by clothing and hair styles in formality, potency, appearance while female undergraduate students in purity, formality, potency. Therefore the religious habits and hair styles had significant effect on korean catholic women's impression of purity, formality, potency, appearance and impression formation was varied according to perceiver's age.

To describe an object realistically is the most important thing in the 3-dimentional space in computer graphics. It is not enough with one or two factors. Several factors should be considered such as perspective sense, cubic effect, material of an object, shadow, strength of light, etc. A shadow algorithm plays an important part in the realistic description of an object. There are many methods to describe a shadow, but it means numerous repeated operations to describe a shadow and it needs much time. We seperate the shadow part and calculate the strength of light for numerous points and it takes much time. This thesis presents a new method to describe a shadow quickly by separating categories maintaining a realistic description of an object.

The purpose of the present study was to identify the effect of perceivers’value and religions on the impresson of Korean catholic priest’s ritual dress. The subject consisted of 415 undergraduated students. The experimental materials developed for this study were 3type color photographs stimuli of catholic priest model and 7-point sementic differential scale composed of 49 bipolar adjectives representing personal traits. Perceivers were differenciated by AVL test. The data were analyzed by factor analysis and analysis of variance. The major findings drawl from this study were as follows : 1) Four factors( openness, religious nature, potency, characteristics of apperance) emerged to account for the dimentional structure of the impression of priest’s ritual dress. 2) The ritual dress and perceivers religion had partially significant effect on the impression of the priest. The ritual dress had an effect on openness and potency while the religious of perceivers affected religious symbolism and potency. Black suit with Roman collar and soutan were seen more authoritative, strong and independent than liturgical vestments. Catholic group saw priest with ritual dress more pure and potent than the other religious groups. 3) The ritual dress and perceiver’s value had partially significant effect on the impression of the priest. The ritual dress had an effect on openness, potency and the value had an significant interaction effect on potency. The group with political value perceived the priest with soutan more potent than black suit with Roman collar and liturgical vestments. Therefore the ritual dress and perceivers’value/religion had significant erect on Korean priest impression of openness, religious nature, potency. Research had also shown the similarity-attraction hypothesis which the individuals who hold similar characterisics are more Likely to be attracted.

The resistance to fracture of the restored tooth may be influenced by many factors, among these are the cavity dimension and the physical properties of the restorative material. The placement of direct composite resin restorations has generally been found to have a strengthening effect on the prepared teeth. It is the purpose of this investigation to study the relationship between the cavity isthmus and the fracture resistance of a tooth in composite resin restorations. In this study, MO cavity was prepared on the maxillary left first molar and then filled with composite resin. Three dimentional model with 3049 nodes and 2450 8-node blick elements was made by the serial photographic method and isthmus (1/4, 1/3, 1/2 and 2/3 of intercusplal distance between mesiobuccal cusp tip and mesiolingual cusp tip) was varied. Two types of model(B and R model) were developed. B model was assumed perfect bonding between the restoration and cavity wall and R model was left unfilled. A load of 1500N was applied vertically on the node from the lingual slope of the mesiobuccal cusp. The results were as follows : 1. There was a significant decrease of stress resulting in increase of fracture resistance in B model when compared with R model. 2. When it comes to stress distribution, the stress was concentrated in the facio-gingival line angle and the buccal side of the distal margin of the cavity in both Band R model. 3. With the increase of the isthmus width, the stress decreased in the area of the facio-gingival line angle, and increased in the area of facio-gingival line angle as well as the buccal side of the distal margin of the cavity in B model. In R model, the stress increased both in the area of facio-gingival line angle and the buccal side of the distal margin of the cavity, therefore the possibility of crack increased. 4. As the width of cavity increased, in B model, the direction of crack moved from horizontal to vertical on the facio-gingival line angle and the facio-pulpal line angle. In R model, the direction of the crack was horizontal on the facio-gingival line angle and moved from horizontal to the $45^{\circ}$ direction on the facio-pulpal line angle.
