The situation and cause of bund collapse in steep sloping paddy area by a heavy rainfall of Chungbuk Province were investigated by field surveys. Shapes of paddy plots are irregular and average size of them is 12.6a. Surface, groundwater and plot-to-plot irrigations are being carried out in the study plots. The type of bund collapse can be divided as follows: overflow type and inundation type. The overflow type generally occurs at the bund with slope lacking the design standard. The inundation type damages paddy plots more seriously than the overflow type. It induces continuous bund collapse from a inflow-plot to a outflow-plot and includes lots of type (inside paddy) collapse, which results in much subsoil erosion. The installation of mountain stream weir and maintenance of mountain stream are proposed to prevent the inundation type collapse.

The purpose of this study was to examine arch form, occlusion in centric occlusion. Male 561 case, Female 305 case were impressioned with alginate impression material, and plaster models were made. Occlusion and maxillary dental arch were studied on plaster models in Korean adults aged from 18 to 60 Years. The results were as follows. 1. The upper dental arch was U-type(57.77%), O-type(23.52%), V-type(18.71%) in male, and U-type(60.66%), O-type(27.11%), V-type(12.13%) in female. 2. The commonest type of the anterior bite was 1-form($68.09{\pm}1.97%$) in male, ($72.46{\pm}2.56%$) in female, and posterior bite was 1-form($65.06{\pm}2.01%$) in male, ($69.51{\pm}2.64%$ in female. 3. In the maxillary dental arch U-type was frequented and the relationship of occlusion in upper and lower dental arch was mainly 1-form.

The purpose of this study is to classify of the Heart shaped Earring in old tombs of Three Kingdom States. First Heart shaped Earring is 7 part in according to heart styles. I-A type was original style and that was influenced by scythe style. I-A II-A type was general style that was found in most of the old tombs in Kokuryo Pacijae ancient Silla Gaya. I-B II-2-A type was also found in most of the old tombs except Kokuryo. Then II-2-A type was transmitted to Japanese Heart shaped Earring. I-A, I-B, II-1, II-2-A type was general style in ancient Silla gaya. Ii-1-B, II-2-B. II-3-A type was excavated from the only Pacjae tombs and II-3-B type was excavated from Kokuryo tombs. II-3-A, II-3-B type was unique style that was found in old tombs in Kokuryo, Pacjae.

This research examines classifying and characterizing breast form's classification on elderly women, 242 subjects from 55 to 75 years of age participated. 27 direct anthropometric measurement were applied to classify the breast typesl. We analyzed measurement data using factor analysis, cluster analysis, analysis of variance. The results of the study were as follows. 1) 55-64 aged group was taller and higher than 65-79 aged group. Typical breast form in 55-64 aged group was more obese than breast form in 65-79 aged group. 2) We extracted 5 factors(obesity of breast, height of breast, height of breast items, location & size of breast, width of upper chest & shouldet length, height of breast & lower length of nipples) from total items through factor analysis. 3) Through cluster analysis, we categorized 3 clusters. Namely, type 1; characterized the best slender type, type 2; characterized middle sized type, type 3: characterized obesity type. Type 2 is the typical type on elderly women.

Purpose: The purpose of this study was to analyze attitude toward dignified dying of Korean students majoring in human service area. Methods: The Q-methodology which provides a method of analyzing the subjectivity of each item was used. The 34 selected Q-statements from each of 38 subjects were classified into a shape of normal distribution using a 9 point scale. The collected data was analyzed using a QUANL PC program. Results: Four types of attitude toward dignified dying from the subjects were identified. Type I is an expression type for happy emotion, Type II is a dislike type for life prolongation, Type III is a pursuit type for relationship improvement, and Type IV is a perception type for family presence. Conclusion: The results of the study indicate that integrating multi-disciplinary curriculum development related to dignified dying and death education for students majoring in human service area are needed.

The channel-type lining board that partial welded on many partition frames is used to normal servicing lining board type. On this study is to investigate existing channel-type lining board's capacity by using the static loading test. From this study, to develop new-type lining board which reflect well cross section area and sectional modulus of existing channel-type lining board. Six types FEM model are adopted. The accumulated test results of stress conditions and deflections by section shapes will be used to analyzed the relation between the capacity and the section shape. With the comparing the results of static loading test and FEM analysis.

The purpose of this study is to investigate the characteristics of the floor plan of single detached houses in Canada. A quantitative & qualitative analysis method of th 260 house plan was used in this study. The followings were found out from this analysis : 1) There were the differences of the lay-out and the number of public spaces between a small type and a big type. 2) There were the differences of the equipment and the number of bathroom between a small type and a big type. 3) The most work center type of kitchen was 'ㄴ+ㅁ' type(33%). 4) The most type of floor plan was that one with attached garage(87%) and center entry(99%). 5) Almost floor plans having 3 or 4 bed rooms even though medium II and large size plans which is to show that the basic needs of family life rely on the omnifarious public spaces.

The objectives of this paper are to study the characteristics of heat transfer and pressure drop of the micro channel heat exchangers using diffusion bonding technology. Four types of heat exchangers are designed and manufactured, which are straight type, long dot type, splited wavy type and straight double side type. Heat transfer and pressure drop performance of each heat exchangers are measured in various operating conditions, and compared each other. The results show that the $(j/f)^{1/3}$ performance of splited wavy type and long dot type increases about 10.3% and 6.1% at the Reynolds number 470 compared to that of straight type, respectively. On the other hand, $(j/f)^{1/3}$ performance of straight double side type decreases 19.7%.

Recently, a study on condensers for refrigerators has focused on new model which will cost less and will be more efficient. Some widely used condensers for domestic refrigerators are wire-and-tube type condenser, hot-wall type condenser, and spiral type condenser. Some companies which use the spiral type condenser at the moment try to develop a new type condenser which will cost less and will be as efficient as the spiral type. The new type condenser consists of a steel tube, steel plates and louver fins attached to the tube. The tube and the plate are bent into a single-passage serpentine shape.
