This study is focusing on Territoriality which is supposed to be one of the most important elements to activate open spaces in apartment communities. Case analysis with onsite visit is selected as the research method of this study targeting 6 apartment complexes in Bukgu and Gwangsangu, Gwangju city which accommodate over 500 households up to 800 households, which show high occupancy ratio and which were built after 2006 to minimize the physical environment variable. The result of this study is concluded as follows. First, we need the elements which can induce various action and the use of floor surface in color, pattern, and material should be considered in the stance of pedestrian for easy recognition of Territoriality change. Second, To secure the view, we should consider to plant shrubs or to plant trees wider apart. In most cases, enclosure is secured by using trees of Vertical Boundary for safety and comfort, but overuse in some cases make residents feel fear of enclosed spaces and insecurity. Third, Various and harmonious design elements can be recommended to increase aesthetic impression, to induce positive response for design, and to be used consistently. Finally, Unique space using notable landmark or design elements should be considered.

We have shown the $Ca^{2+}$-activated chloride current is present in cardiac myocyte in rabbit pulmonary vein (Kim et al., 2002). This current amplitude was increased as [N $a^{+}$]$_{i}$ was increased and we suggested this chloride current may be involve in the spontaneous action potential frequency change. Since this current is activated by the increase of intracellular $Ca^{2+}$, we would like to test what is the inducer of the increase of [C $a^{2+}$]$_{i}$ between a L-type $Ca^{2+}$-current or a reverse mode of N $a^{+}$-C $a^{2+}$ exchange current. White rabbit (1.5 kg) was used and anesthetized with Ketamin (100 mg/kg). Pulmonary vein (PV) was isolated and sleeve area between left atrium and PV was dissected. Using collagenase (Worthington 0.7 mg/cc), single cardiac myocytes were isolated. In the presence of 15 mM of N $a^{＋}$, three steps of voltage pulses were applied (holding potential : -40 ㎷, -80 ㎷ for 50 msec, 30 ㎷ for 5 msec, 10 ㎷ steps from -70 ㎷ to 60 ㎷). The inward and outward tail current was activated after brief 5 msec prepulse. The outward tail current was blocked by the removal of extracellular chloride substituted by glucuronic acid or by a chloride channel blocker, 5 mM 9-AC. But the inward tail current was still remained even though the amplitude was decreased. The reversal potentials were changed to the direction of the change of chloride equilibrium potential ( $E_{Cl}$ ) but the shift of equilibrium potential was not enough to match to the theoretical equilibrium potential shift. In the presence of L-type $Ca^{2+}$ channel blocker, nifedipine 1 uM, inward tail currents were greatly reduced but the outward current tail currents were still remained. In the presence of N $a^{+}$-C $a^{2+}$ exchange current blocker, 10 uM KB-R7943, the inward and outward tail currents were blocked almost completely. We tried to test the $Ca^{2+}$sensitivity of the chloride current with various [C $a^{2+}$]$_{i}$ in pipette solution from 100 nM to 1 uM but we failed to activate $Ca^{2＋}$-activated chloride currents even though the cell became contracted in the presence of 1 uM $Ca^{2+}$. From these results, we could conclude that the increase of [C $a^{2+}$]$_{i}$ to activate the outward $Ca^{2+}$-activated chloride current was mainly induced by the activation of the reverse mode of N $a^{+}$-C $a^{2+}$ exchanger, But for the increase of [C $a^{2+}$]$_{i}$ to activate the inward tail current, L-type $Ca^{2+}$ current may be the major provoking current. Since the cytosolic increase of [C $a^{2+}$]$_{i}$ through pipette solution have failed to activate $Ca^{2+}$-activated chloride current, this chloride current may have very low $Ca^{2+}$ sensitivity or a comparmental increase $Ca^{2+}$ such as in subsarcolemmal space may activate the chloride current. Since there are several reports and models that the increase of $Ca^{2+}$ in subsarcolemmal space would be over several to tens of uM, both possibility may be valid together.uM, both possibility may be valid together.

With the continuous expansion and updating of modern cities, the historical and cultural space of ancient city is under increasing impact from the expansion of modern cities. At present, the regeneration and protection of the ancient city has achieved remarkable results together with poor results. Based on this background, this paper has revealed the power operation behind the space production of three regenerated ancient cities with 'spatial practice', 'representation of space' and '"representation of space' as the framework to, and pointed out the influence of stake holders on space shaping and analysis on the construction of regeneration model. From the perspective of specific materials, society, power, and culture, this paper has analyzed the methods of regeneration construction of Wuzhen ancient city, and provided new methods and reference values for how to regenerate and protect ancient cities. Based on these studies and analysis of the regeneration issues in ancient cities and villages, other historical cultural areas, the paper has indicated that it is necessary to coordinate with the government to clarify the issue of property rights, as well as planners and managers, to activate the regional culture and integrate it with modern culture.

This study aims to analyze the aesthetic thought and expression tendency appeared in contemporary architecture by looking at today's architectural art based on the concept of the uncanny that Sigmund Freud contended as an aesthetic principle, of the aesthetic concepts tossed around to define the contemporary times in the aesthetics field and discuss the architectural analysis possibility of the concept of the uncanny. The generation structure of the uncanny that generates experiences of fear and surprise is classified into dual structure, trauma, threatening structure, and repetition compulsion. This is the principle that evokes a sense of experiencing subject, incorporates sensibility, and vitalizes internal process. This is also the methodology to organize and structure the concept of the uncanny. When seen from the four factors drawn from the concept of the uncanny and aesthetic expressions, the uncanny expression characteristics of contemporary architecture includes isolation, subversion, trace, absence, oblique line, flotation, concealment, and disturbance. Isolation and subversion refers to producing the space of the pressure of tension and relaxation caused by repression and relief from repression and eliciting the maximum expansion of the sense of space through spatial change. Trace and absence indicates being able to elicit more intense emotions from the experiencing subject by applying the images of alienation and absence in the way to reproduce historical trauma. This happens by implementing the potential value of physical activity. Oblique line and flotation means visual impulse. This happens in the way to visualize uneasy points. This causes uncanny by threatening the survival. Finally, concealment and disturbance refers to creating unpredictable space. The concept of masquerade and maze space composition are applied in the way to activate spatial perception, including space exploration and unintended subject's forced selection. As stated above, the uncanny expression characteristics shown in contemporary architecture can be presented as indicators that are available to analyze the undecided and diversified contemporary architecture aesthetically. In this respect, this study has great significance.

This study intended to establish a direction for the revitalization of youth culture centers by examining the current status of youth centers operated in Daejeon and how they have been used. Four youth centers in Daejeon were visited and a survey was conducted targeting 180 people using the centers. Frequency, Mean, and ${\chi}^2$ analysis were performed by using SPSS statistics package, and major research outcomes are as follows; There were 6 youth culture centers in Daejeon and showed a lower construction rate of 7.4% on the basis of 81 up, myun and dong. Most youth centers were small, around $300-500m^2$ in total floor area, and accommodated 100-200 people, and the space comprised multipurpose hall, cafeteria, open space, club space, multimedia space, information service room, and guide booth. There were no sports spaces among the target facilities. So, it has created the need for physical activity space to promote health & development. Most users visited centers with their friends and simply to use the facilities, and the satisfaction with the facilities was relatively high at 4.32. The role of the local community and financial support of the government is required to activate the youth culture. Also, for the role of youth culture center, it was suggested that the youth culture center should develop program which corresponds with the level of the youth and boast the interest of the youth.

In the current digital age, most of the countries in the world recognize the electronic business to be a very prospective area in the future and plan to activate for the preoccupation of the business. As a result, this led a rapid increase of the electronic business volume. Electronic business takes place in the cyber space, using internet. However, the intellectual property rights have a high degree of possibility of being infringed as the digitalized intellectual property is easy to receive, copy and transmit in the cyber space. The language structure on the web, represented by HTML, makes easier to copy the intellectual property. And, as the internet has no national boundary, the infringement of the intellectual property rights is easier regardless of country, which could lead to the commercial disputes between the concerned countries. There are in fact many legal disputes nowadays on the infringement of the intellectual property rights in such field as computer programming, infringement of the copyright, business model patent and infringement of the trademark right on the registered name of the domain. It is, therefore, time now to prepare a new theory or legal system to protect the intellectual property rights on copyright, patent and trademark right so as to comply with the digital environment together with such a splendid growth of "electronic business." USA and Germany are nowadays making a significant movement on the legislation of the electronic business, and this study will focus on the legislative contents, judicial precedents and interpretation of law in the above countries.

We present the properties of circumnuclear gas associated with the AGN located in the center of Abell 1644-South. A1644-S is the main cluster in a merging system, which is also known for gas sloshing in its core as seen in X-ray. The X-ray emission of A1644-S shows a rapidly declining profile, indicating the presence of cooling gas flow. This flow of cool gas may fuel the supermassive black hole embedded in the brightest cluster galaxy, leading to the activation of the central AGN. Indeed, we find a parsec-scale bipolar jet feature in the center of A1644-S in our recent KaVA observation, which implies that its central AGN is likely to have been (re)powered quite recently. In order to verify the hypothesis that cooling gas flow in the cluster core can (re)activate the central AGN, we probe the cold gas properties of the central 1 kpc region of A1644-S using the archival VLA and ALMA data. Based on the spatially resolved morphology and kinematics of HI and CO gas, we challenge to identify inflow/outflow gas streams and clumps. We study the role of circumnuclear cool gas in fueling the centrally located cluster AGN in the cool-core environment. We also discuss how the feedback due to the (re)powered AGN affects the surrounding medium.

In this paper, an efficient computational algorithm for the implementation of the newly proposed node activation technique is presented, and its computational aspects are thoroughly investigated. To verify the validity, convergence, and efficiency of the node activation technique, various numerical examples are worked out including the problems of Poisson equation, 2D elasticity problems, and 3D elasticity problems. From the numerical tests, it is verified that one can arbitrarily activate and handle the nodal points of interest in finite element model with very little loss of the numerical accuracy.

Sometimes, literary therapy is to create an abscission layer at the mind and remove the signifier of love, by the abscission layer. The purpose of this study is to reveal the mechanism of literary therapy by mutation in human-created sentences and to activate literary therapy. In Gosijo, the abscission layer of Seo Gyeongdok's mind is present in the layer of the "falling leaf" of the his Sijo's last sentence, and the abscission layer of Hwang Jin-yi's mind exists in the layer of the "falling leaf" of the her Sijo's last sentence. The "falling leaf" created by the abscission layer of Seo Gyeongdok's sentence acts as an action potential to the nervous system of Hwang Jin-yi. In Hwang Jin-yi's Sijo, the abscission layer is also activated, forming a "leaf". Hwang Jin-yi's Sijo constructs a new sensory layer that is extended and mutated more than the meaning of space between lines of Seo Gyeongdok's Sijo. In her Sijo, Hwang Jin-yi twists and twists Seo Gyeongdok's sentences to squeeze the sound. She accepts the Seo Gyeongdok's sentences and twists in the first sentence and twists out of the second sentence once more to produce the mutation in the last sentence. As a result of her sentence twist, Seo Kyung-duk's visual sense of "falling leaf" is mutated into a "falling leaf's sound" of auditory sense. This mutation process works as a healing mechanism in the human body. If this study will continue in the future, it will be possible to activate literary therapy by Sijo.
