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 maintenance cost plays a important role to plan the scale of the apartment housing such as a number of household, building area and building type. Therefore, it is required to forecast the cost considering various maintenance characteristics. The maintenance characteristics are floor area, number of household, heating type, site area and etc.. In addition, the maintenance cost are classified into 5 area. These are a personal expense, facility maintenance cost, energy and water cost, insurance and sanitary cost. These five cost area are related with various characteristics and brought up the estimation model using the stepwise multiple regression analysis. The energy and heating cost share over the 50% in the total cost and the personal expense cost shares about 40%. The personal expense cost per area is 5,272 won/$m^2{\cdot}yr$ irregardless of heating type and the district heating type is a higher cost than other type. In facility maintenance cost, the central heating type is 2,015 won/$m^2{\cdot}yr$ and higher than other type. The estimation models have good statistics in each model. Most of the model have a determination coefficient over 0.7 and Durbin Watson value between 1.5 and 2.5.

The objective of the study was to provide fun-damental data on somatotype for elderly women by classifying the somatotype and analyzing the characteristics of their somatotype. The subjects were 368 women ages of 60∼84, they were measured direct anthropometry. In or-der to find out differences among the age groups, the 368 subjects were grouped into two age groups(Group 1 aged 60 to 69, Group 2 ; aged 70 to 84) Data were analyzed using Factor analysis, Cluster analysis, Duncan test and Analysis of variance. The results of this study were as follows. 1. The characteristics of Elderly women's somatotype were bending of the upper-torso, fat-ness of the waist and abdomen, drooping of the bust and shoulder and hip. In addition, height, girth, depth and width items were decreased in their sizes respectively. 2. Through the factor analysis, we extracted 5 factors from anthropometric measurements. Factor components were obesity, height, girth of the leg and arm, length of the upper-torso except the center front length, the center front length, we categorized by 4 clusters using 5 factor scores. And after the cluster analysis using 5 factor scores, 4 clusters were categorized. The characteristics of clusters were as follows. Type 1 was characterized by short, obesity type, and droopy bust. Type 2 was characterized by short and slender type, dropped bust, and bending somatotype from the lateral view. Type 3 was characterized by middle sized and straight somatotype from the lateral view. Type 4 was characterized by tall and obese type from the lateral view.

To protect the power systems from fault current, the rated protective equipment should be installed. However growth of power system scale and concentration of loads caused the large fault current in power transmission system and distribution system. The capacities of installed protective equipment have been exceeded the due to increase of fault current. This increase is not temporary phenomenon but will be steadily as long as the industry develops. The power system operator need a counter-measurement for safety, so superconducting fault current limiter (SFCL) has been received attention as effective solutions to reduce the fault current. For the above reasons various type SFCLs have been studied recently. In this paper, operation characteristics and power burden of trigger type SFCL is studied. The trigger type SFCL has been used for real system research in many countries. Another trigger type SFCL (double quench trigger type SFCL) is also studied. For this paper, short circuit test is performed.

The breakup characteristics of liquid sheets formed by the impinging and swirl type injectors were studied as increasing the Weber number (or injection condition) and the ambient gas pressure to 4.0.MPa. In the case of impinging type injector. we compared the changes of breakup lengths between laminar and turbulent sheets. which are formed by the impingement of laminar and turbulent jets. respectively. The results showed that both sheets expand as increasing the injection velocity irrespective of the ambient gas density when the gas based Weber number is low. When the Weber number is high, however, the breakup of turbulent sheet depends on the hydraulic force of jets as well as the aerodynamic force of ambient gas which determines the breakup of laminar sheet. Using the experimental results. we could suggest empirical models on the breakup lengths of laminar and turbulent sheets. In the case of swirl type injector. as $We_l$, and ambient gas density increased, the disturbances on the annular liquid sheet surface were amplified by the increase of the aerodynamic forces. and thus the liquid sheet disintegrated near from the injector exit. Finally, the measured breakup length of swirl type injector according to the ambient gas density and $We_l$, was compared with the result by the linear instability theory. We found that the corrected breakup length relation derived from linear instability theory considering the attenuation of sheet thickness agrees well with our experimental results.

본 연구에서는 지오그리드로 보강된 사각형 복합 인공어초의 침하 및 세굴 특성을 알아보기 위해 대형 수조 침하 실험, 2차원 흐름 수조 실험 등 다양한 실내 실험을 수행하였다. 또한 인공어초의 각 배치 형태(배치도 A; 나란히 배치된 형태, 배치도 B; 지그재그로 배치된 형태)에 따른 세굴 특성을 알아보기 위해 수치해석을 수행하였다. 실내 실험 결과 무보강된 인공어초에 비해 지오그리드가 보강된 인공어초의 침하 및 세굴 깊이가 크게 저감되었다. 인공어초 배치 형태에 따른 세굴 특성을 알아보기 위한 흐름 수조 실험과 수치해석을 수행한 결과 배치도 A의 세굴 깊이와 유속 벡터는 배치도 B보다 더 감소하는 경향을 보였다.

This study is to classify the somatotypes of middle-aged women by many critera and figure out he characteristics of each somatotypes. The subjects are 614 middle-aged women between 35 and 59 years old and the research is based on anthropometric and photometric measurement by photographing their body parts. The results are as follows; 1. The result of factor analysis indicated that 11 factors were extracted through factor analysis and orthogonal rotation by the method of varimax and those factors comprised 85.71 percent of total variance. 2. As the result of cluster analysis the group of the middle-aged women is classified as 6 types. Type 1 is short, fat, H type in front and lean-back type on the side. Type 2 is standard in height and weight. Type 3 is standard height, fat, long upper body, bend-forward type and protrude of the hip on the side. Type 4 is tall, thin, short upper body, having clearly protrude of the back and hip and lean-back type on the side. Type 5 is neither short nor tall, slim, X type in front and I type on the side. Type 6 is tall, thin and B type on the side. 3. As the result of observing the mutual corresponding relation between these 6 groups and age/Rohrers Index, the somatotype of the middle-aged women is divided at the age of 45. Accordingly when it comes to progress the study of the middle-aged women in the future, we will have to observe the characteristics for dividing the first half and the second half of age of 45.

The theoretical and experimental current-voltage characteristics of Erbium silicided n-type Schottky barrier tunneling transistors (SBTTs) are discussed. The theoretical drain current to drain voltage characteristics show good correspondence and the extracted Schottky barrier height is 0.24 eV. The experimentally manufactured n-type SBTTs with 60 nm gate lengths show typical transistor behaviors in drain current to drain voltage characteristics. The drain current on/off ratio is about 10$^{5}$ at low drain voltage regime in drain current to gate voltage characteristics.
