This paper describes analytical investigation into a new dual function system including a couple of shear links which are connected in series using chevron bracing capable to correlate its performance with magnitude of earthquakes. In this proposed system, called Chevron Knee-Vertical Link Beam braced system (CK-VLB), the inherent hysteretic damping of vertical link beam placed above chevron bracing is exclusively utilized to dissipate the energy of moderate earthquakes through web plastic shear distortion while the rest of the structural elements are in elastic range. Under strong earthquakes, plastic deformation of VLB will be halted via restraining it by Stopper Device (SD) and further imposed displacement subsequently causes yielding of the knee elements located at the bottom of chevron bracing to significantly increase the energy dissipation capacity level. In this paper first by studying the knee yielding mode, a suitable shape and angle for diagonal-knee bracing is proposed. Then finite elements models are developed. Monotonic and cyclic analyses have been conducted to compare dissipation capacities on three individual models of passive systems (CK-VLB, knee braced system and SPS system) by General-purpose finite element program ABAQUS in which a bilinear kinematic hardening model is incorporated to trace the material nonlinearity. Also quasi-static cyclic loading based on the guidelines presented in ATC-24 has been imposed to different models of CK-VLB with changing of vertical link beam section in order to find prime effectiveness on structural frames. Results show that CK-VLB system exhibits stable behavior and is capable of dissipating a significant amount of energy in two separate levels of lateral forces due to different probable earthquakes.

On this study, a multipurpose operating system was developed to adjust a configuration of a moving path which have no connection with a form of greenhouse. To being performance the multipurpose working system, we have experienced growth quality on the plants in greenhouse. Some of the results are as follows. While watering by the hand spray. the condition of plant was generally no good. It was shown that plant height and leaf area were all high without wind during watering by the automatic spray. The effect to retrain a plant growth was high as a ventilation was strong. The diameter of a plant stem was small without ventilation condition during watering 3 times by automatic spray. The number of leaf was relatively large during 3 times by automatic spray compared to 2 times by automatic spray or hand spray. Growth of plant was fast as the times of spray were large.

Xinjiang Uygur Autonomous Region is the area with the most Muslim populations in China and the costume of this ethnic minority group was influenced from its surrounding environment and religion. Headgear is one of the important costume elements of Muslim ethnic minority such as Kazakh, Kirghiz, Uzbek, and Tadzhik people, and each group has developed narious forms of it. Especially, we can notice characteristics of headgear in Xinjiang Uygur and four ethnic minority groups through women's headgear pursuant to motive of wear, classification of type, differences and comparability with other areas. Thus, purpose of this study is to investigate women's headgear of Muslim ethnic minority in Xinjiang Uygur Autonomous Region. Based on local data at the Xinjiang Uygur Museum, the study referred to Chinese ethnic minority costume and literature data as well as advanced researches related to Islam, and analyzed characteristics of women's headgear of four ethnic groups in connection with Muslim formation background in Xinjiang Uygur. Women's headgear of Muslim ethnic minority in Xinjiang Uygur can be largely divided into three types; cylindrical, conical and hood type. Headgear was influenced not only by natural environment and weather for protection of body, but also by Islam. Along with strong desire for decoration and expression of racial features, it was used as a means of race discrimination and representation of identity. The religion of Islam within these four ethnic groups grew in accordance with tradition of existing nomadic tribes and regional characteristics, and women's headgear developed in various ways added with religious precepts and nomadic features. Taking everything into consideration, it is found that women's headgear of Kazakh, Kirghiz, Uzbek, and Tadzhik people developed, adopting their own living style and features of minority races instead of remaining identical to the headgear type of Muslim countries in other area.

Architecture and Fashion mutually affects the shape and appearance of the other as an art of space according to the hybrid trends. Therefore, the purpose of this study is to find the correlations between the characteristics of traditional architecture types in Southeast Asia and modern fashion. Firstly, characteristics of the types obtained through the theoretical consideration of Southeast Asian architectural tradition include vertical, symmetrical, geometrical, epeated and continual structure. On the basis of these characteristics analyzed from 2013's S/S to 2015's F/W collection of Alexander McQueen, Gareth Pugh, Victor & Rolf, designers with strong creative and experimental minds who juxtaposed designs of two opposing points as well as hybrids since 2000, the following formativeness exists. First, the vertical structure of high floor is represented as a straight silhouette, a color contrast, vertical cut or wrinkle. Hence, it impresses verticality, rhythm, etc. Second, symmetrical structure of the gable roof is represented as a trapezoidal shape starting from the shoulder line or neck line widened into sleeves, impressing symmetry, dynamism, etc. Third, the geometry of the assembled is represented as vertical and horizontal bands or pattern pieces like puzzle, impressing geometry, three-dimensional, etc. Fourth, repeated structure of the weaving pattern is represented as repetitive patterns of woven fabric or printing techniques. Thus, it impresses repeatability, harmony, etc. And lastly, continuous group structure is represented as a connection of collars or hem-lines, as well as a crossing of fabric that impresses continuity, liquidity, etc.

We came to the conclusion as follows from the research about pulse diagnostic technique (脈診) out of "Nan Jinghoeju jeonjung" (難經滙注箋正). 1. "Nan Jing" is practical medical book for clinician and holds different opinions about three portions and nine takings(三部九候脈法) from Huang Di Nei Jing's Taking the pulse of Bu Jung Chim Chon Kwan Chuk((浮中沈 寸關尺) is a quite creative means which has been a important role to future generation. 2. We pointed the differences between western medical science and traditional medical science. And can explain the pulse in western medicine divided from twelve channels of Oriental Medicine. We can explain special connection between heart and lungs using the theory of systemic & pulmonary circulation in western medicine. And this can be a basement of Lung controls every pulse theory in oriental medicine. 3. We have negative assertion about viewing the human body using theory of Yin and Yang-Five Elements. And have poor opinion of explaining about the matching internal organs to Chon Kwan Chuk using the theory of Yin and Yang-Five Elements. 4. We pointed out the mistake that Porak & Sang hwa act for heart. We took pulses considering heart is a real actual internal organ as others. 5. We denied the theory of Man's Chuk pulse is always weak(男子尺脈恒弱) & Woman's Chuk pulse is always strong(女子尺脈恒盛). The physical form of man and woman is not different from each other considering their inheritances from forefather & same shape of organs. So, we cannot insist on the theory.

The ultrastructure of epididymal epithelium of 10, 20, 35 and 80 day-old mouse was observed to study the differentiation and function of the epithelial cells in connection with the absorption and secretion during sexual matruation. The differentiation of epididymis was divided into three phases of, 1) undiflerentiated phase until the day 20 after birth, 2) growing and differentiating phase between the day 20 and 35, and 3) maturating phase up to the adult. Each phase was closely related with the lumination of seminiferous tubule and the influx of spermatozoa within testicular fluid from testis. In adult, the ultrastructural features appeared an absorptive function in the principal cells of proximal caput epididymis, and a strong activity of protein synthesis and secretion in distal caput, corpus and cauda epididymis. Clear cells were predominantly located in corpus and cauda epidiymis, and plenty of absorption vesicles including membranous particles assumed to be the cellular residues from spermatozoa were observed at apical region. Therefore, the distribution of various cell types of epithelium and the ultrastructure even in the same type of epithelial cell, were different according to the epididymal regions.

Recently, small and medium-sized hospitals which are located in rural areas have many difficulties in securing high quality nurses. That is because working environments for nurses in small and medium-sized hospitals in rural areas are poor compared with those of big hospitals in urban. As a result, the migration of nurses from small and medium-sized hospitals in rural areas to big hospitals in urban is continuously happening. In general, big hospitals provide nurses with high level of salary and fringe benefits. To prevent the migration of nurses, chief executive officers of small & medium hospitals in rural areas have been interested in improving nurses' working conditions including wages. Also, they have raised nurses' salary and improved working conditions. But, basically these individualized efforts have some limit. In connection with this, medical interest groups have produced various voices in terms of interpretation and solutions for these issues. However, from the future perspectives, it seems evident that two approaches for both manpower supply and demand plans of nurses are necessary. They should contain not only accurate estimation of the supply-demand of nursing manpower but also the improvement of working conditions and wages of nurses. Estimation of nursing manpower supply-demand depends on the standards and criteria being used. Supply and demand may be met or not in accordance with the points emphasized on the decision. In the articles, issues regarding nursing manpower, levels of salary, other working conditions and social support system for child care are discussed. According to Joe's report (2005), most health institutions did not meet the guidelines of nurse staffing in Medical Law. The wages of nurse vary on every hospital and there is a big difference in wages' range. The average starting salary for a nurse is 22 million won a year. In case of tertiary hospitals, it reaches up to 30 million won a year. Nurse as a profession should have a strong responsibility and should take care of the patients for 24 hours with three working shifts. Also, most of them are female who have the burden of child rearing. Therefore, it is suggested to increase the salary, to provide comfortable working conditions, and to have social support system for nurses with household affairs.

The purpose of this study is to examine the dynamic properties, especially the damping and fatigue properites, of NR vulcanizates and to find out the vulcanizate which can be used as damping materials in industry. The results of this study can be summarized as follows: 1. In the ODR test, the S-2 vulcanizate was the fastest one in terms of having reached to optimum cure times($t_{90}$) and, with the same formula, when 50phr of HAF carbon black loaded, the shortest optimum cure times has shown. 2. The S - 2 vulcanizate was the best than the others in the physical properties. In aging properties, however, the E - 1 vulcanizate appeared to be better than the other vulcanizates. 3. The results of the RDS test for the NR vulcanization system under the condition of 0.1% strain amplitude and 1 Hz frequency showed no connection between Tg and the the nature of the crosslinking system, but 50phr loading of HAF carbon black increased Tg. The damping values of vulcanizates in the elastic region showed a strong relations the damping values and the crosslinking system. The S - 2 vulcanizate with higher crosslink density had lower damping values than other vulcanizates, and furthermore, the SH - 2 vulcanizates with 50phr loading of HAF carbon black increased the damping values. 4. The Goodrich Flexometer test showed that the heat buildup for the gum NR vulcanizates was less than for those which contained 50phr of HAF carbon black. In particular, the fatigue life of the vulcanizate with lower damping values appeared to be longer than that of the vulcanizates with higher damping values. In the fatigue test, the increasment of the loading or the temperature, applied to the vulcanizates, appeared to be shorten their fatigue life.

'Video Commerce' has grown significantly, and is in the era of so-called V-commerce 2.0. Based on this background, this study focused on the link and the possibility of creating synergy between V-commerce 2.0 content and MCN, and examined the linkage strategy considering its characteristics. In conclusion, first, V-Commerce has evolved into the age of 2.0, centered on the characteristics of content that are oriented towards fun and sympathy, beyond the 1.0 era. Second, V-commerce 2.0 content has the characteristic of replacing the sharing and recommendation based on the nature of SNS networks as promotion and purchase enhancement. Therefore, competitiveness as 'content' is relatively important before 'commerce'. Third, V-commerce 2.0 and MCN industry have a strong connection with each other in terms of securing core competitiveness and creating a new profit model. In order to create the synergy between V-Commerce 2.0 and MCN, we proposed the use of big data to reinforce V-Commerce 2.0 customized content competitiveness, building of storytelling marketing and branding, and enhancement of live performance and interactive communication.

Camouflage is evaluated by scientific principle in the fields of biology, military science, and art. It has a strong influence on contemporary fashion and means exposure with concealment. This study analyzed the visual characteristics of camouflage patterns in fashion design through documentaries and fashion photos. The fashion design results areas follow. The simple blending of a disruptive motif indicated an inaccurate repetition of a disruptive motif, the discontinuous or continuous connection of disruptive motif, the irregular repetition of a disruptive animal silhouette, the collage of a different disruptive motif, the craft of a disruptive motif and the intensive color match of a disruptive motif. It represented the maximization of complication, fantastic and fanciness. The overlap of a disruptive motif showed the overlap of disruptive print patterns with transparency and an overlap of different fabrics with a disruptive pattern. It represented spatial relationships of three dimensions as well as the maximization of visual illusion and the reinforcement of attractiveness. The blurring of a disruptive motif showed the pointage of disruptive motif, the pointage of image, value gradation, the whole blurring of a disruptive pattern cluster and stained appearance. It represented the obscurity of motif form, the uncertainty of object and double meaning. The trompe l'oeil of a partial background object showed the realistic and the painterly imitation of color and texture for partial objects through a close-up. It represented amazement and pleasure by illusion, scarcity and the decoration of surface and synecdochical remind. In conclusion, camouflage in fashion was weakened and modified from a classical military context by a unique expression of various motifs.
