Somatotype is human body shape and physique type which can be classified not only by the size, but also by the shape or posture of the body. Postural variations in the alignment of the back, shoulder, and neck can have an adverse effect on the fit of garments designed to hang from the shoulders. There have been some previous studies about the lateral upper torso by analyzing photographic measurements. In this study, 3D body scan images were used to classify the side somatotype of upper lateral method even though they are major data in the classification of upper torso. This study focused on following objective.; 1) To apply new and developing technology into the apparel industry analyzing 3D body scan images. 2) To classify upper laterla torso using the data through the new improver technology, 3D body scanner. 3) To propose basic materials for well fitted garments for each type of figure. The test subjects for this study were two hundreds nine female aged 19 years and up who were recruited in Cornell university body scan research team. Seventeen Variables(12 angles, 5 lengths) out of 3D body scan data were measured based on these landmarks and applied to analyze. The result of factor analysis indicated that 6 factors were extracted through factor analysis and orthogonal rotation by the method of Varimax and those factors comprise 62.5% of total variance. And the somatotype of upper body is classified into 3 types of figures according to cluster analysis; Bent forward posture, Straight posture, Swayback posture. Future study could be addressed about the somatotype of body by the age group based on the large database with wide variety of age.

This research examined the effects of Narcissism as socio-psychological factor and physical features such as BMI on the selfie behavior. The participants of the study were SNS users aged 20-29 years recruited in Daegu and surrounding areas. Statistical analysis including factor analysis, ANOVA, cluster analysis and regression was done using SPSS 23.0 to analyze the results. Two groups with high other-dependent Narcissism showed higher levels of Cosmetic surgery management and clothing management compared to other groups. Among 4 clusters divided by BMI, the lower the BMI, the higher the level of appearance management behavior except for body management. Other-dependent Narcissism and BMI have been shown to have a significant effect on selfie behavior in the relationship of Narcissism, BMI and selfie behavior. In the relationship between appearance management behavior and selfie behavior, only beauty treatment management influenced selfie improvement behavior, and all appearance management behaviors affected selfie complement behavior. Fashion brands should use the relationship between Narcissism, appearance management behavior and selfie behavior in planning selfie related events on SNS as well as consider active collaboration with cosmetics brands. It is necessary to investigate selfie behavior from a more diverse perspective by expanding future research targets and diversify related variables.

CSF is a major concern for the swine industry, representing currently the most epizootically dangerous disease to the species. Numerous CSFV isolates with various degrees of virulence have already been isolated worldwide, ranging from low virulent strains that do not result in any apparent clinical signs to highly virulent strains that cause a severe per acute hemorrhagic fever with very high mortality. The molecular epidemiology of CSFVs has proven to be an essential tool for effective disease control and the development of safe and effective vaccines. Therefore, this study cloned and sequenced local CSFV isolates, and conducted a phylogenetic analysis based on the E2 glycoprotein encoding sequences.The RNA was extracted from PK15 cell culture passaged CSFV isolates, the cDNA prepared, and the complete E2 gene amplified with a product size of 1186 bp. The gelpurified PCR product was cloned into a pGEMT easy vector and the positive clone commercially sequenced. Aligning the nucleotide (1119 bp) and amino acid (373) sequences with 29 reference strains revealed nucleotide and amino acid sequence identities of 82.60-97.80% and 88.70-98.70%, respectively, indicating a higher mutation rate of the field CSFV strains. The phylogenetic analysis based on the complete E2 amino acid sequences also revealed a reliable differentiation of all the analyzed strains into specific genetic groups and subgroups, plus the local isolate (CSFV-E2) was found to cluster with the CSFV subgroup 2.2. Thus, the full-length E2 cds proved to be most suitable for a reliable and statistically significant phylogenetic analysis of CSFV isolates.

This study analyzes the velocity and pressure incurred by protruding shapes installed within the inlet part of a pressurized membrane module during operation to determine the fluid flow distribution. In this paper, to find the flow distribution within a module, it investigates the velocity and pressure values at cross-sectional and outlet planes, and 9 sections classified on outlet plane using computational fluid dynamics. From the Reynolds number (Re), the fluid flow was estimated to be turbulent when the Re exceeded 4,000. In the vertical cross-sectional plane, shape 4 and 6 (round-type protrusion) showed the relatively high velocity of 0.535 m/s and 0.558 m/s, respectively, indicating a uniform flow distribution. From the velocity and pressure at the outlet, shape 4 also displayed a relatively uniform fluid velocity and pressure, indicating that fluid from the inlet rapidly and uniformly reached the outlet, however, from detailed data of velocity, pressure and flowrate obtained from 9 sections at the outlet, shape 6 revealed the low standard deviations for each section. Therefore, shape 6 was deemed to induce the ideal flow, since it maintained a uniform pressure, velocity and flowrate distribution.

Korean Food Globalization has been launched as a tool of civil ambassador and the high value-oriented industry. According to department of statistics in 2012, the trend of Korean food globalization from international visitors of Chinese and Japanese has grown. Hence, this study is purposed to identify the level of satisfaction of Chinese and Japanese consumers based on their food-related lifestyle. The survey was conducted by interviewing 403 Chinese and Japanese visitors who have experienced Korean food. The survey questionnaire was composed of 3 parts of demographic information, food-related lifestyle, and satisfaction of Korean restaurant. As factor analysis results, 3 factors were yielded for the food-related lifestyle factors-a eat-out preferred group, a health preferred group, and a taste preferred group, and 3 factors were generated for Korean restaurant satisfaction-hygiene and service, menu, and food quality. For cluster analysis, 3 clusters were identified as follows: high interested in food itself, health interested, and taste interested. Female appears to be significantly different in terms of 3 clusters than male. Nationality shows that Chinese consumers showed a high interest in food itself whereas Japanese consumers were high interested in health. With regard to Korean restaurant satisfaction, service appeared to be important in Chinese consumers while Japanese consumers showed a higher mean value on serving size, price, and nutrition. The findings concluded that by understanding the nature of food-related lifestyle of international visitors, marketing strategies can better meet visitors' expectations and increase their satisfaction with Korean restaurants.

This study is a preliminary study to suggest a distinguished fitted sloper according to body types. To this end, this study classified body types of men in their 20s in an attempt to examine the characteristics of each type. A total of 842 adult men of age 20 to 29 were studied by using the direct measurement data taken in the 6th Size Korea. The subjects' body types were classified based on 48 measurements. We extracted a total of six factors that characterized the body types of adult men in their 20s: horizontal size, vertical length, shoulder development, trunk area length, hip area length and shoulder slope. Result of the cluster analysis, the body shapes of men in their 20s were classified into four types. We developed the overlapped silhouettes for each of the four body types and compared the front and side shapes to clearly identify the differences of each body types. The findings of this study indicated that Korean adult men in their 20s can be classified into the big inverted triangular type that represents healthy and muscular men, the small inverted triangular type that represents short and skinny men, the triangular type that represents men with abdominal obesity, and the rectangular type that represents men that are fat overall, with a fairly even distribution of each body type.

This study investigated design factors and removal efficiencies of a sheet flow channel as natural type water improvement techniques in the stream. The channel was designed considering the design factors, then constructed and monitored in the test bed of the Osan stream's floodplain. Water lever, velocity, discharge, T-P, T-N, and NO₃-N were monitored and the removal efficiencies and design formula were suggested. Overall efficiencies of T-P, T-N, and NO₃-N range 10 - 20%, and they show consistent relations with residence times. Minimum velocity requirement is also suggested from the relation of algae conditions and velocities. Relation formula of residence time and removal efficiency will be applicable in the design and operation process of a sheet flow channel.

This paper aims to evaluate the Industrial Complex Campus Program and to provide policy recommendations for promoting effectiveness of industrial complex campuses through the in-depth case study on the Changwon Industrial Complex Campus Program. The survey shows that the program contributes to not only strengthening the R&D capacities of SMEs within the cluster, but also promoting the interactions between local companies and local universities. But it claims that the industrial complex campus program reveals some limitations to supporting effectively local enterprises. First, It is necessary to maintain regional balance in terms of the sites of the implementation of the program. Second, the policy management plan and the monitoring system of the program should be established for the purpose of the self-reliance of industrial complex campuses, regardless of the government financial support.

The leakage of hazardous materials due to the defect in storage tank foundations is likely to cause tremendous fire disasters in the industry cluster area. Thus, adequate design and construction of the tank foundation is required for preventing tank leakage. In this study, four types of typical tank foundations were classified and modeled for 3D FEM analysis to perform stability evaluation on tank foundations. Furthermore, numerical analysis indicated that stress concentration just below the tank shells is 40 times that at the tank center. The settlement influence zone is about the tank radius and tank diameter in the horizontal and vertical directions, respectively. Thus, the appropriate guidelines for the design and construction of tank foundations were suggested via a comparison assessment of the numerical analysis results on the stress distribution and displacement of the tank foundations.

This study introduced the concept of 'Media-content repertoire', which indicates the set of favorite media-content combinations of media users and extracted five media user types based on those combinations. We used the range of media(i.e., smartphone, tablet, PC, and TV) and entertainment content(i.e., movie, broadcasting, music, and game) for the analysis. Also, we investigated the differences between those types including demographic variables, individual characteristics, and content buying behavior and we found that statistically significant differences exist among them. Those include 'non-user'(i.e., lower level of media use), 'screen user'(i.e., 50s, TV-centered media use), 'variety seeker'(i.e., 20s. heavy public transport user), 'selective focus'(i.e., 20,30s, movie&broadcasting-centered media use), and 'heavy user'(i.e., high level of media use and consumption). The results provide both academic implications(e.g., extension of media repertoire concept) and practical implications(e.g., direction to the target marketing for each user type).
