Three kinds of tight skirts, slim type, straight type, and semi-tight type were investigated to obtain necessary information about the size of the back slit. Fourteen college students put on these experimental clothes and walked on the flat floor, going up and down the stairs. The dimensions of the back slit were measured by width and length. The stride length was taken from the record of footprints of walking. The correlation between the body measurement, stride length and the size of the back slit was studied. As a result of this experiment, the findings are as follows: 1. The size of the back slits differed from each skirt type at the level of p<0.001. In the case of walking on the floor, the average dimension of the back slit was 14.0 cm long 5.0 cm wide for the slim type,9.5 cm long 2.8 cm wide for the straight type and 2.1 cm long 0.5 cm wide for the semi-tight type. 2. In the case of walking on the stairways, the average dimension of the back slit was 16.0 cm long 5.8 cm wide for the slim type, 12.4 cm long 3.9 cm wide for the straight type and 3.1 cm long 1.1 cm wide for the semi-tight type. 3. The correlation between the height (stature, waist height, knee height) and the size of back slit was 0.3 to 0.6. The correlation between the girth (waist, hip) and the size of back slit was 0.3 to -0.5. 4. The correlation between the stride length and the size of back slit was 0.76 for the slim skirt, 0.56 for the straight skirt, 0.28 for the semitight skirt.

A new steel sheet pile of wide hat-type was developed. Advantage of using wide type of sheet pile is reducing steel weight and consequently cutting down construction cost. Field driveability tests were conducted in order to verifying vibro-driveability of wide hat-type sheet pile. As a result of the tests, penetration rates of newly developed sheet piles were less than those of U-type sheet piles. Axial stresses developed in sheet pile during driving were fur less than yield stress of sheet pile. Futhermore, initial penetration rates of sheet piles were much larger than those obtained from WEAP program.

The main purpose is to study lines on different body types and to disguise any imperfections by using diverse princess lines. We separated festers body shapes into specific body types, A, H by applying both the direct and the indirect measurements. Following are the results of the study: 1. nose are the resulting illusion effects when the shoulder width of the princess line was fixed. In case of the armhole princess line, the illusion that the waist intervals were narrow or wide in A-line silhouette. In case the shoulder princess line, when the waist interval was narrow, it appeared to show narrow shoulder in A-line silhouette. While the wide waist interval shows the wide shoulder width in H-line silhouette. It regards body type H in the same light as H-line silhouette when the waist interval is narrow, it appeared to show narrow shoulder width in A-line silhouette. When the waist interval was wide, it appeared to give the narrow shoulder width. 2. When the princess lines waist width was fixed in order to study illusion effects of waist widths. Generally, for body type A, Whether the waist interval princess line is narrow or wide, the princess line is located comparatively wide, in A-line silhouette appeared to show relatively slender waist. For body type H, whether the waist interval is narrow or wide, the princess line us situated comparatively narrow interval, H-line silhouette appeared to show sum waist but the differences are not significant 3. The illusion of the hip were studied by fixating the width of the skirt and varying the locations of princess line and waist widths. For the location of both armhole and shoulder princess line in H and A-line silhouette, the narrow shoulder width and the waist appeared to show narrow hips. mile they are wide appeared to show wide hips. 4. With both waist and skirt width fuel, all two body types showed taller and slender postures when the princess line originated from the shoulder compare to the armhole.

^x In Korea, we are entering on a new phase that the use concept of urban park is extending to dynamic activities such as games and sports. This article is to investigate the significance of lawn areas, as a receptive space of such a wide range of recreation activities. As a study process, Green Styles (type of parks) such as Garden Type, Park Type and Forest Type were studied and historical review of lawn areas in park development was performed. In conclusion, the lawn areas ( greensward) are an essential part of park and open space organization. The significance as a conclusion is presented as follows : 1 ) Balance in type of parks The structures of our parks and open spaces are inclined toward the artificial Garden Type and natural Forest Type. Therefore, the intermediate Park Type and sparse wood areas should be a core part of our park and open space development. 2) Psychological effect Park Type areas, thorned by greensward(lawn area), can refresh urban dwellers with natural picturesque landscaps, and Park Type landscape is the most preferred natural landscape. It shows the essence of natural amenity as 3) Accomodation of wide range of recreation activities Lawn areas in urban park are the best place in accomodating the wide range of active and massive recreation activities. Thus, lawn areas can increase the freedom of recreation use in urban park. 4) Enlargement of physical carrying capacity. With expansion of lawn areas of euro- american concept, the structural open space can be transformed into service open space. Thus, the recreation carrying capacity of urban parks can be enlarged.

In this paper, a CPW fed and inversed U-type monopole structure wide slot antenna for novel broadband calacturictics is proposed. To enhance the impedance bandwidth of the wide slot antenna, we proposed the wide slot structure with cpw-fed which is combined with four $\lambda/2$ rectangular radiation modified monopole and inductively coupled. The measured impedance bandwidth is about 2.3 GHz(3.85~6.15 GHz) at 10 dB and the simulated antenna gain is about 6 dBi at 5.4 GHz.

Over the past decade, the detection of gene-gene interactions has become more and more popular in the field of genome-wide association studies (GWASs). The goal of the GWAS is to identify genetic susceptibility to complex diseases by assaying and analyzing hundreds of thousands of single-nucleotide polymorphisms. However, such tests are computationally demanding and methodologically challenging. Recently, a simple but powerful method, named "BOolean Operation-based Screening and Testing" (BOOST), was proposed for genome-wide gene-gene interaction analyses. BOOST was designed with a Boolean representation of genotype data and is approximately equivalent to the log-linear model. It is extremely fast, and genome-wide gene-gene interaction analyses can be completed within a few hours. However, BOOST can not adjust for covariate effects, and its type-1 error control is not correct. Thus, we considered two-step approaches for gene-gene interaction analyses. First, we selected gene-gene interactions with BOOST and applied logistic regression with covariate adjustments to select gene-gene interactions. We applied the two-step approach to type 2 diabetes (T2D) in the Korea Association Resource (KARE) cohort and identified some promising pairs of single-nucleotide polymorphisms associated with T2D.

The success of genome-wide association studies (GWASs) has enabled us to improve risk assessment and provide novel genetic variants for diagnosis, prevention, and treatment. However, most variants discovered by GWASs have been reported to have very small effect sizes on complex human diseases, which has been a big hurdle in building risk prediction models. Recently, many statistical approaches based on penalized regression have been developed to solve the "large p and small n" problem. In this report, we evaluated the performance of several statistical methods for predicting a binary trait: stepwise logistic regression (SLR), least absolute shrinkage and selection operator (LASSO), and Elastic-Net (EN). We first built a prediction model by combining variable selection and prediction methods for type 2 diabetes using Affymetrix Genome-Wide Human SNP Array 5.0 from the Korean Association Resource project. We assessed the risk prediction performance using area under the receiver operating characteristic curve (AUC) for the internal and external validation datasets. In the internal validation, SLR-LASSO and SLR-EN tended to yield more accurate predictions than other combinations. During the external validation, the SLR-SLR and SLR-EN combinations achieved the highest AUC of 0.726. We propose these combinations as a potentially powerful risk prediction model for type 2 diabetes.

The purpose of this study was to present basic data for development of shoe last suitable for women of plus size (BMI 25 kg/㎡ or higher) by type and to analyze the characteristics of each type of foot type. The results of the study are as follows. A comparison of the feet of a plus-size woman and a normal-weight woman showed that the feet of a plussize woman were thicker and wider in the toes, cheeks and feet than those of a normal-weight woman, while the ankle area was thicker. As a result of the cluster analysis by type of foot type of plus-size woman, type 1 was classified into four types, type 1 was 49 (19.5%), type 2 was 43 (17.1%), type 3 was 53 (21.1%), and type 4 was distributed among 106 (42.2%). Type 1 appeared to be a long, low heel, thick foot and wide H-type, and Type 2 appeared to be a D-type with a low heel and a thinner and narrow foot compared to other types, but with wide outer width of the foot. Type 3 showed short feet, low heels, narrow feet, but slanted sides, and Type 4 showed type A with long feet, high heels, thick and wide feet or a combination of toes.

A BC-B type bulk carrier is rarely built, so the structural characteristics is not reported and familiar so far. The biggest difference between BC-B and BC-A type vessel is applying alternate cargo loading, which density is over $1.0ton/m^3$. In this paper, 150K DWT class BC-B type bulk carrier is calculated and compared with BC-A type vessel, which has same condition such as main dimension and deadweight, about prescriptive rule and FEA based on CSR. And aspect ratio of target vessel is smaller than typical capsize bulk carrier, so 150K and 180K bulk carrier, which applied BC-A type, are also compared to find feature of wide beam vessel.
