  • This research is an experimental study on BIPV Power performance of See-through a-si and Light-through applying external curtain wall. In case of See-through a-si Photovoltaic, appropriateness of facade applying standard($950\;{\times}\;980mm$) large($950\;{\times}\;1960mm$)area photovoltaic was examined. Transparent performance was also investigated through Power simulation according to angles and seasons of See-through a-si and Light-through Photovoltaic so that Power output was surveyed with using designed and manufactured Mock-up. When comparing See-through a-si to Light-through Photovoltaic for simulation Power output on angles based on full south aspect, which the result was that See-through a-si Power output according to Light-through Power output was the highest of 65.5% when applying a 90 degree angle. Monthly accumulated average Power output during winter seasons (December, January and February) applying a vertical plane on full south aspect was analyzed, which results in 66.37W/h of See-through a-si and 139.1 W/h of Light-through. See-through a-si Power output showed 47.7% in comparison with Light-through transparent. Also monthly, hourly average Power efficiency according to solar radiation during winter seasons (December, January and February) was that 4.7% of See-Through a-si and 9.8% of Light-through.

  • Through-space and through-bonds interactions between two nonbonding orbitals are shown to be first-order and second-order perturbations of nonbonding orbitals by the framework sigma orbitals. Through-space interactions for diamines and triplet diradicals are always destabilizing, but through-bonds interactions are stabilizing owing to their coupling with through-space effect. Anomalies in level ordering and magnitudes of energy splitting can be rationalized with the present approach. Orbtial interactions predicted with the PMO method were found to be consistent with those obtained by STO-3G calculations and photoelectron spectroscopy.

  • The present paper provides plastic limit load solutions of axial and circumferential through-wall cracked pipes based on detailed three-dimensional (3-D) finite element (FE) limit analysis using elastic-perfectly-plastic behavior. As a loading condition, axial tension, global bending moment, internal pressure, combined tension and bending and combined internal pressure and bending are considered for circumferential through-wall cracked pipes, while only internal pressure is considered for axial through-wall cracked pipes. Especially, more emphasis is given for through-wall cracked pipes subject to combined loading. Comparisons with existing solutions show a large discrepancy in short through-wall crack (both axial and circumferential) for internal pressure. In the case of combined loading, the FE limit analyses results show thickness effect on limit load solutions. Furthermore, the plastic limit load solution for circumferential through-wall cracked pipes under bending is applied to derive plastic $\eta\;and\;{\gamma}$-factor of testing circumferential through-wall cracked pipes to estimate fracture toughness. Being based on detailed 3-D FE limit analysis, the present solutions are believed to be meaningful fur structural integrity assessment of through-wall cracked pipes.

  • The inhibitory action of oxymetazoline on the spontaneous movements of isolated intestinal strips of the rabbit and the effects of antagonists upon the oxymetazoline actions were assessed with recordings through both isometric and isotonic transducers, and comparisons were made between both methods of recording. There were significant differences between the slopes of regression equations calculated from log dose response curves of oxymetazoline obtained from jejunum and those from ileum. But no difference was noted between both recordings either through isotonic transducer or through isometric transducer. The $ID_{50}$ of oxymetazoline obtained from the recording through isotonic transducer was $6.31{\times}10^{-7}M$ in jejunum and $3.16{\times}10^{-8}M$ in ileum. The recording through isometric transducer gave the values of $5.01{\times}10^{-7}M$ in jejunum and $1.07{\times}10^{-8}M$ in ileum. The $pA_2$-values of prazosin to oxymetazoline calculated from the recording through isotonic transducer were 8.13 in jejunum and 8.31 in ileum and the recording through isometric transducer gave the values of 7.29 and 8.26 in jejunum and ileum, respectively. The $pA_2$-values of phentolamine to oxymetazoline obtained from the recording through isotonic transducer were 8.18 in Jejunum and 9.31 in ileum and those from the recording through isometric transducer were 7.75 and 8.13 in jejunum and ileum, respectively. These results indicate that there are no significant differences between recordings either through isotonic transducer or through isometric transducer in assessing inhibitory responses of intestinal movement to certain drugs.

  • Dresses reflecting human aesthetic consciousness are used as a way of expressing the inner desire of human beings. The desire to attract the opposite sex through sexual appeal among the human inner desires is the one innate characteristic that all human beings have. We may say that the $See-through$ look emphasizes a sense of softness and femininity by exposing the skin and expresses bodily beauty by way of using see-through cloth. It is a fashion style that can express sexual appeal and eroticism of female most effectively. In this study, after observing the motivation of dress wearing and $See-through$ look in the perspective of bodily concept and eroticism, colors of $See-through$ look shown in the $Pret-a-Porter$ Paris S/S collection from 2006 and 2007, a fashion style expressing eroticism was newly re-analyzed as romanticism and glam look particularly in 60, 80s compared with other times were re-created and evaluated. As a result of analyzing colors of the $See-through$ look, Yellow Red(close to skin color) was revealed to be the highest( 31.3%), followed by Red(9%), Purple Blue(7.2%), Yellow(7.2%), Purple(5.4%), respectively and in terms of color tone, pale and gray tones that have a sense of femininity and softness was revealed to the highest(20%) followed by ltg(11%) and dkg(9%). We may find the meaning of this study in analyzing colors of the $See-through$ look, and the typical look of eroticism, which has never been tried before. It is required to identify chronological color features of the $See-through$ look and the diversified characteristics of skin colors expressed in them to prepare useful data by which a sense of the $See-through$ look can be utilized for color coordination through the relationship between skin tone and dress by pursuing a more detailed method based on the result of this study.

  • Objectives : This study aims to examine the exterior relief method through pungent-cool properties in comparison to pungent-warm properties historically, to understand the meaning of 'exterior relief through pungent-cool' more thoroughly. Methods : Contents mentioning the treatment method directly were examined historically, then analyzed. Results & Conclusions : The method to relieve the exterior through pungent-cool properties has developed by overcoming the limitations of the method to relieve the exterior through pungent-warm properties since it was first established in 『Shanghanzabinglun』(『傷寒雜病論』). The term 'relief of the exterior through pungent-coolness'(辛凉解表) was first mentioned in the Ming period, referring to weak level of perspiration. Yetianshi(葉天士) explained it as communicating Weiqi(衛氣) using pungent-cool medicinals for heat to discharge through the exterior, resulting in mild sweating. In 『Wenbingtiaobian』(『溫病條辨』) the term 'to relieve the flesh'(解肌) refers to both mild sweating through pungent-warm medicinals and the opening of the exterior through pungent-cool medicinals for pathogenic qi to exit, resulting in sweating. If the exterior relief of the pungent-warm medicinals happens through the warm Yang qi(陽氣) stimulated the inner Yin fluids(陰液) to discharge as sweat, that through pungent-cool medicinals relieves stagnation in the exterior, opening up a way for the pathogenic heat to exit. From the perspective of the main therapeutic mechanism for pungent-cool medicinals to be its coolness relieving heat, the term 'exterior relief through pungent-coolness' becomes erroneous. For the 'exterior relief through pungent-coolness' category to be valid, the meaning of 'exterior relief' needs to be expanded to include not only stimulated sweating but the treatment process that could result in sweating.

  • Twelve push-out test specimens were conducted with various parameters to study the static and fatigue performance of a new through-bolt shear connector transferring the shear forces of interface between prefabricated hybrid fiber reinforced concrete (HFRC) slabs and steel girders. It was found that the fibers could improve the fatigue life, capacity and initial stiffness of through-bolt shear connector. While the bolt-hole clearance reduced, the initial stiffness, capacity and slippage of through-bolt shear connector increased. After the steel-concrete interface properties were improved, the initial stiffness increased, and the capacity and slippage reduced. Base on the test results, the equation of the load-slip curve and capacity of through-bolt shear connector with prefabricated HFRC slab were obtained by the regression of test results, and the allowable range of shear force under fatigue load was recommended, which could provide the reference in the design of through-bolt shear connector with prefabricated HFRC slabs.

  • Wall obstruction is the main factor leading to the non-line of sight (NLoS) error of indoor localization based on received signal strength indicator (RSSI). Modeling and correcting the path loss of the signals through the wall will improve the accuracy of RSSI localization. Based on electromagnetic wave propagation theory, the reflection and transmission process of wireless signals propagation through the wall is analyzed. The path loss of signals through wall is deduced based on power loss and RSSI definition, and the theoretical model of path loss of signals through wall is proposed. In view of electromagnetic characteristic parameters of the theoretical model usually cannot be accurately obtained, the statistical model of NLoS error caused by the signals through the wall is presented based on the log-distance path loss model to solve the parameters. Combining the statistical model and theoretical model, a hybrid model of path loss of signals through wall is proposed. Based on the empirical values of electromagnetic characteristic parameters of the concrete wall, the effect of each electromagnetic characteristic parameters on path loss is analyzed, and the theoretical model of regional path loss of signals through the wall is established. The statistical model and hybrid model of regional path loss of signals through wall are established by RSSI observation experiments, respectively. The hybrid model can solve the problem of path loss when the material of wall is unknown. The results show that the hybrid model can better express the actual trend of the regional path loss and maintain the pass loss continuity of adjacent areas. The validity of the hybrid model is verified by inverse computation of the RSSI of the extended region, and the calculated RSSI is basically consistent with the measured RSSI. The hybrid model can be used to forecast regional path loss of signals through the wall.
