There have been numerous researches on Nak-An village in Jeollanamdo, one of the most representative traditional castle village in Korea. Most of them have dealt with general and physical architectural scale and features separately. Therefore this study aims to understand the compositional characteristics of building layout and exterior space and the relations between street system and dwelling unit of folk houses in Nak-An village. The study examined houses of ordinary people in Nak-An village constructed before the village was not affected by foreign influences. 36 folk houses in Nak-An built from nineteenth century to early twentieth century and believed to have few physical changes from the original floor plans and architectural forms were the subjects to be analyzed. The most popular types in building layout are "Open L"and "Open U". The most typical orientation of main building is Southwest. The favorable entry into the dwelling lot is from the side. The street system in the village consists of main streets of South-North, resulting in dwelling lots with North-South axis most general. This site condition forces the entry into the lot from North main street and the side access to the main building. From these findings, the building layout and the entry into the dwelling lot of folk houses in Nak-An are strongly related with street system and conditions of dwelling lot.

Despite the proliferation of studies on emotion, little attention has been paid to the effects of discrete emotion on political participation. Using a representative survey conducted on a sample of South Korean citizens in the aftermath of the Sewol ferry accident, the current survey explored how anger and sadness, as well as the ways people express those emotions, influence the orientation of their response in social environments and, ultimately, their voting intention. The results partially supported the discrete effects of sadness and anger in eliciting reactions of approach or avoidance. Anger was found to provoke an approach action tendency in independent voters and supporters of the opposition, while also eliciting an avoidance action tendency with a varying effect size across all three groups of respondents. Sadness also prompted an approach action tendency in independents and supporters of the incumbent party, while it manifested a negative association with the avoidance action tendency in supporters of the opponent party. An interpretation of the findings and proposed directions for future research are presented.

A comprehensive research must be conducted on manufacturing techniques such as patterns and sewing, with the understanding of material properties to satisfy consumers' emotions with a strong fashion trend orientation. Physical and emotional characteristics may change depending on the characteristics of the material, and the overall silhouette and feeling of the garment can change depending on how sewing is conducted.To examine the completeness of a finished garment depending on different kinds of clothing material, this study fabricated an actual garment and a 3D virtual garment as well using 3D CAD IMAGE SYSTEM (CLO 3D, DC Suite, etc.) for a comparative analysis. These two methods have their own advantages and disadvantages. This study selected five of the most representative clothing materials and conducted a comparative analysis on appearance differences between actual clothing and virtual clothing by material. Additionally, the study verified the similarity between actual clothing and virtual clothing by comparing their physical properties by material, and evaluated the objectivity and accuracy of the reproducibility of material properties of virtual clothing.

The effects of nanotechnology and smartness on the buckling reduction of pipes are the main contributions of present work. For this ends, the pipe is simulated with classical piezoelectric polymeric cylindrical shell reinforced by armchair double walled boron nitride nanotubes (DWBNNTs), The structure is subjected to combined electro-thermo-mechanical loads. The surrounding elastic foundation is modeled with a novel model namely as orthotropic nonhomogeneous Pasternak medium. Using representative volume element (RVE) based on micromechanical modeling, mechanical, electrical and thermal characteristics of the equivalent composite are determined. Employing nonlinear strains-displacements and stress-strain relations as well as the charge equation for coupling of electrical and mechanical fields, the governing equations are derived based on Hamilton's principal. Based on differential quadrature method (DQM), the buckling load of pipe is calculated. The influences of electrical and thermal loads, geometrical parameters of shell, elastic foundation, orientation angle and volume percent of DWBNNTs in polymer are investigated on the buckling of pipe. Results showed that the generated ${\Phi}$ improved sensor and actuator applications in several process industries, because it increases the stability of structure. Furthermore, using nanotechnology in reinforcing the pipe, the buckling load of structure increases.

Swelling and fibrillation of two kinds of lyocell, $Tencel^{(R)}$ and $Lyocell^{(R)}$, were investigated using polarizing and scanning electron microscope (SEM). $Tencel^{(R)}$ of a representative lyocell showed that loop tenacity which is related to wrinkle and resilience of fiber does not show significant reduction in wet state. Two kinds of lyocell exhibited surprising degree of swelling in aqueous NaOH solution under free tension. Diameters of $Tencel^{(R)}$ and $Lyocell^{(R)}$ swelled up to 670% and 830%, respectively in the range of around 10% NaOH concentration. Molecular orientation estimated by birefringence also reduced remarkably in alkaline solution. Moreover, diameter and birefringence which changed in alkaline solution did not recovered to original level even after washing and drying. Fibrillation of $Lyocell^{(R)}$ fiber observed by SEM seems to be easier than that of $Tencel^{(R)}$. In order to understand the difference between $Tencel^{(R)}$ and $LyoceJl^{(R)}$, further study on the structure of the two fibers will be followed.

In recent years, 'technological fusion or convergence' has drawn a lot of attention of innovation researchers and governmental policy makers as the driving force of technological innovation and industrial growth. There are, however, few studies on the analysis of longitudinal trends of technological convergence and its comparison between global and national level. In this study, with the citation data of about 18 million articles, we analyzed 1) the growth of representative convergence research areas, 2) the convergence of citing patterns between research fields, and 3) the changing trend of diversity index of all research fields. We conclude that technological convergence in korea shows the relatively strong orientation to the combination of neighboring fields than that of heterogenous fields in comparison to global trend. In particular, the relatively weak activity of cognitive science and the low level of mutual exchange between arts/humanities/social sciences and natural/engineering sciences in Korea are emphasized.

In this paper, inverse building modeling was applied to building perimeter zones which have different window orientation. Two test zones of east-facing and west-facing zones in ERS(Energy Resource Station) building, which is representative of small commercial building, was used to test performance of cooling load calculation and peak cooling load reduction. The dynamic thermal load model for the east and west zone was validated using measured data for the zones and then it was used to investigate the effect of peak cooling load reduction by adjustment of indoor cooling temperature set points during on-peak time period. For the east zone, the peak load can be reduced to about 60% of the peak load for conventional control even without any precooling. For the west zone, PLR is nearly independent of the start of the on-peak period until a start time of 1pm. Furthermore, PLR has a small dependence on the precooling duration. Without any precooling, the peak cooling load can be reduced to about 35% of the peak load associated with conventional control.

The study was to investigate kinematic difference between flexed and extended type of knee during Jigeo-Cha-Gi in Taekwon-Do. For this subjects participated were consisted of weights of fin (1), bantam (1) and welter class(1) of male 3 national representative level skilled in two type(flexed and extended type) of Jigeo-Cha-Gi. 3D cinematography analysis was performed for motion analysis and Kwon 3D ver. 3.1) was used for 3D coordinates & analysis variables calculation. In Temporal variable there was no significant difference statistically in all phases & total elapsed time between flexed and extended type, but flexed type was delayed more 0.016 sec than extended type. In displacement of COG there was significant difference in level of p<.05 showing longer mean 6.13 cm in case of flexed type than extended type in displacement of COG during all phase and too significant difference in level of p<.01 showing longer mean 4.4 cm in case of flexed type than extended type in displacement of COG in follow through phase. In velocity of COG there was significant difference in level of p<.001 showing higher mean 15.53cm/s in case of flexed type than extended type in velocity of COG(Y direction) during targeting phase and peak velocity(Y) was more fast 8.74 cm/s in extended type than flexed type. In velocity of leading leg in forward direction(Y) there was significant difference in level of p<.05 showing higher thigh mean value in case of flexed type than extended type but showing higher foot mean value in extended type at level of p<.001 than flexed type in velocity of COG(Y direction). In velocity of leading leg in vertical direction(Z) there was no significant difference in the second & third phase in case of vertical velocity level, but momentum transferred efficiently form proximal to distal endpoint. In front-back & right-left orientation angle of trunk there was possibility of more stable Jigeo-Cha-Gi in extended than flexed type by decreasing in right-left orientation angle of trunk. In relative angle of lower leg(hip, knee, ankle) there was significant difference in level of p<.001 showing longer mean 32.74 deg. in case of flexed type than extended type in hip joint during the second phase but maintained insufficient extended knee of mean 168 deg. in targeting phase.
