The AGN unification model suggested the presence of obscuring material, a dusty torus, to explain the various types of AGN. IR SED model fitting is a crucial tool to probe the structure and properties of the dusty torus. We use a sample of 16 local quasi-stellar objects in Martinez-Paredes et al. (2017) with obtained NIR and MIR high-angular resolution (~0.3") imaging data from EMIR, CIRCE and CanariCam on the 10.4-m Gran Telescopio CANARIAS (GTC) while 4 objects have NIR high-angular resolution photometry from NICMOS/HST from the literature. The unresolved NIR emission from the NIR image analysis and low-resolution Spitzer/IRS spectra are used to construct NIR-MIR SEDs covering a larger spectral range. We investigate the sensitivity of the geometrical (e.g. viewing angle) and physical parameters (e.g. optical depth) of the clumpy dusty torus model of Nenkova et al. and the clumpy disk+outflow model of Hoenig et al. We aim to investigate the minimal dataset needed to well constrain the parameters of the models and derive the properties of the dusty torus. These results will allow us to plan future observations for a larger sample of high luminosity AGNs with the James Webb Space Telescope and the Giant Magellan Telescope.

Currently, China's urban space is gradually changing from gradual development to inventory transformation. The planning and development goals of urban communities have also shifted from material space construction to the direction of sustainable development of humanities and society. Currently, community planning and construction at a single latitude, which focuses on residential life, overlooks the multidimensional elements of community life production, causing many problems such as cold relationships between communities and difficulties in forming relationships between humans and the environment. Therefore, this article re-recognizes the sociality of the community in the continuous unification of the community in time and space, clarifies the central and private aspects of the community, and re-explores the dynamic creation and methods of the community as the starting point of daily life.

The increasingly high prices for oil, the exhaustion of fossil fuels as well as concern about global warming are driving rapid growth of alternative sources of energy in the world. The active solution for global environment and exhaustion of energy sources is to develop and popularize the technologies to use natural energy such as sunlight, wind, and water. PV(Photovoltaic) modules are efficient devices that has been considered a logical material for use in buildings. Recent advanced BIPV(Building Integrated PV) technology have rapidly made PVs suitable for direct integration into construction in the world. Recently, building has been higher and higher. Tall buildings have many advantages for BIPV such as wide facade area and no shading effect by the surrounding buildings. However. BIPV has not been applied for tall building facade yet. Therefore, the purpose of the research is to develop suitable BIPV for tall buildings and to put these technologies to practical use. Therefore, the purpose of the study is to investigate unification of BIPV to curtain wall to apply BIPV on tall building through research into advanced application of overseas BIPV cases.

Mobilization is defined as a use of national authority to effectively control, manage and utilize all personnel and material resources of a nation in a national emergency situation. Therefore, the complete posture of mobilization many deter war and secure victory as well as serve as a driving force for national economy during peacetime The future of military mobilization policies will need to be developed in relation to other government and administrative departments. Also mobilization of reserve forces can increase its swiftness and effectiveness by integrating the civilian, governmental and military departments. Additionally, the mobilization of military reserve forces policy after the unification in this Peninsula will need to be developed through active researches.

This study is to review research issues on North Korea and unified territory in terms of topics and approach method in Korean human geography. The conclusion of this paper is as follows. Before 1980's, topics on political geography, such as geopolitics or unified land, were the main stream in research. In 1990's with the end of the cold war and the access to material which was published in North Korea, scope of research was widened especially in geography education. After 2000's with the expansion of cooperation between South and North Korea, the scope of topics were more expanded in all field of human geography, for example, critical geopolitic in political geography, Gaeseong Industrial Complex, Najin-Seonbong region in economic geography, place names, Geumgangsan, North Korean defectors in social and cultural geography. The approach method of toward North Korea is fall into two categories. One is regional geography and the other is the unified land. In the latter approach, topics on the regional structure after reunification or on the life adaptation of defectors in South Korea etc. were studied. After unification of land, new Korean Studiea will be established and human geographers should make ready for this. Before unification, research on the land in north Korea should be proceeded in terms of historical geography.

Instead of metal connector generally used on the structural glued laminated timber rahmen joints, the GFRP reinforced laminated plates combining veneer and GFRP (Glass Fiber Reinforced Plastic) and bonded type GFRP rod were used as the connectors. As a result of moment resistance performance evaluation on the joint part applied with these connectors, the yield moment of specimen using the GFRP reinforced laminated plates and GFRP rod pin was measured 4 % lower in comparison to the specimen (Type-1) using the metal connectors, but the initial rotational stiffness was measured 29% higher. Also, the yield moment and rotational stiffness of the specimen using the GFRP-reinforced laminated plates and wood (Eucalyptus marginata) pin showed were measured 11% and 56% higher in comparison to the Type-1 specimen, showing the best performance. It was also confirmed through the failure shape and perfect elasto-plasticity analysis that it showed ductility behavior, not brittle fracture, from the shear resisting force by the pin and the bonding strength increased and the unification of member was carried out. On the other hand, in case of the specimen bonded with GFRP rod, it was impossible to measure the bonding performance or it was measured very low due to poor bonding.

The unified scheme of Seyfert galaxies hypothesizes that the observed differences between the two categories of Seyfert galaxies, type 1 (Sy1) and type 2 (Sy2) are merely due to the difference in the orientation of the toroidal shape of the obscuring material in the active galactic nuclei. We used in this paper, a sample consisting of 120 Seyfert galaxies at 1.40 × 10⁹ Hz in radio, 2.52 × 10¹⁷ Hz in X-ray and 2.52 × 10²³ Hz in γ-ray luminosities observed by the Fermi Large Area Telescope (Fermi-LAT) in order to test the unified scheme of radio-quiet Seyfert galaxies. Our main results are as follows: (i) We found that the distributions of multiwave luminosities (L_radio, L_X-ray, and L_γ-ray) of Sy1 and Sy2 are completely overlapped with up to a factor of 4. The principal component analysis result reveals that Sy1 and Sy2 also occupy the same parameter spaces, which agrees with the notion that Sy1 and Sy2 are the same class objects. A Kolmogorov-Smirnov test performed on the sub-samples indicates that the null hypothesis (both are from the same population) cannot be rejected with chance probability p ~ 0 and separation distance K = 0.013. This result supports the fact that there is no statistical difference between the properties of Sy1 and Sy2 (ii) We found that the coefficient of the best-fit linear regression equation between the common properties of Sy1 and Sy2 is significant (r > 0.50) which plausibly implies that Sy1 and Sy2 are the same type of objects observed at different viewing angle.

Taijiquan is possible for us to use not only as a martial art, but also as a physical exercise and a way to discipline human mind, and so it is called 'moving-Zen' and is a martial art to discipline human body and mind against different diseases and stress of modern adult people caused by our modern advanced civilization. We can look at natural passion as one of the most fundamental categories in Philosophy as a minimum material unit comprising all nature. Taijiquan is an exercise with natural passion, flowing through all the body, leading the natural passion with our mind, and moving our body with the natural energy. Also, all the motions in Taijiquan were made based on Yin and Yang. Taijiquan is a discipling way to reach Taegeuk through Yin and Yang and to train ourselves together. The realization of Taegeuk is to reach Taegeuk through the discipline of Taegeuk and can lead to Taegeuk through the unification of the inside and the outside(內外合一), the mutually complementing(剛柔相濟), the circling of the heavenly body(周天) of Taijiquan. The strength and the weakness help each other, the mind and the body is unified, the mixture of the rapidness and the slowness is appropriate, the form and the consciousness are combined into one and move, naturally unified into one(形意結合), and progressive and regressive Junsakyung are combined and move, naturally forming Turoh(套路) where Yin and Yang are unified. The discipline of Taijiquan is not only for maintaining our health, but also for leading to Taegeuk, an ultimate entity, which had existed before the day when all things were generated as its essence and has existed since then.

As the consumer market in the cosmetic, vehicle manufacturing and aerospace industries grows, the demand for manufacturing industries using on injection mold technology. Also, such manufacturing technology of metal machining is expensive, and the shape is limited. Cosmetic cushion fact products are divided into outer relevant to the exterior of the product and inner containers containing the actual contents. In the case of the inner container, it needs to be combined with the upper and lower cases. As environmental regulations are strengthened internationally, the use of a large number of component parts can result in significant losses in recycling and economics. Therefore, this study aims to perform injection molding analysis through injection molding simulation to develop a cushion fact container that can be recycled through the unification of products and materials using polypropylene to cope with environmental regulations. In the case of injection molding conditions, Injection Time(sec): 4.5, Cooling Time(sec): 13, Resin Temperature($^{\circ}C$): 240, and Pressure(MPa): 30 were determined. The results of injection molding simulation according to the two design methods were compared with the sync mark which shows the problem of filling and injection molding.
