  • Traditional industrial complex in inner city has been getting stagnant and deteriorating because of the improvement of industrial structure and change of the city's spatial restructuralization. Third Industrial Complex is also characterized by the deterioration in the field such as the reduction of average number of the workers and the amount of production, the change of main types of business, subdivision of many parts, and the change of the price of land. Thus, local government is planning to change the complex into a high-tech industrial complex in the inner city. On the other hand, the companies which are undergoing the direct deterioration do not fully recognize the government plan to redevelop the complex, and there is no counter measure against the stagnation and deterioration. Therefore, the local government must have much time to discuss and have a consensus with the companies in the complex, and organize the control office which is able to mediate between the local government and the companies.

  • The study on the characteristics of nitrous oxide catalytic decomposition was carried out to utilize the nitrous oxide as a propellant. The Pt, Ir and Ru were synthesized to select a high performance catalyst for the nitrous oxide decomposition reaction. The respective catalyst precursors were loaded in the $Al_2O_3$ support using an wet impregnation method. The $N_2O$ conversion as a variation of space velocity and reaction temperature was measured using a tubular reactor. The catalyst loss was measured to evaluate the durability of catalysts after the reaction at $800^{\circ}C$ for 2 hours. The $N_2O$ conversion was increased at the decrease of space velocity and at the increase of temperature. The Ru/$Al_2O_3$ catalyst had the highest $N_2O$ conversion at low temperature and the best durability.

  • When cadastre system was first introduced in Korea, we only uses the surface of the land and thus its form was very simple. Nowadays on account of the development of architectural technology, the rapid expansion of population and urbanization, the cubic utilization of land including the land usage of underground and surface space is widely settled. This article studies the function of cadastre and public notice to encourage cubic utilization of the land, argues the necessity of 3D-cadastre system to protect property right, and suggests the GPS land measurement as a possible measure.

  • Propellant pressurization system in liquid rocket propulsion system plays a role in supplying pressurant gas at a controlled pressure into the ullage space of propellant tanks. The most important design parameter for such propellant pressurization system is the temperature of pressurant gas fed from pressurant tank, which is placed inside of cryogenic propellant tank. Such pressurant is gaseous state, of which density is very sensitive to the temperature of pressurant. Previous investigation dealt with thermal correlation of pressurant and external fluid at room temperature. This study investigates the temperature variation of cryogenic pressurant (GHe) at the time when the pressurant is coming out of pressurant tank, which is submerged in a liquid oxygen, experimentally as well as numerically.

  • Recently, many people can experience the virtual space by smartphone, and they use many games. In particular, this change has great implications in the collaborative and communicative planning paradigm, which is residents' participation and agreement becoming important in community making and urban design. This study analyze the case of the five virtual space games about community making and urban design, and examine the related regal system. Game users can construct roads, houses, buildings and facilities in the virtual city. Then, they create profit, and promote the growth of virtual city. In these games, construction elements are classified residential, commercial, industrial, parks, green spaces, public building, and roads. But these elements does not identified clearly, and they mixed. By analyzing of related regal system, these games focus on the individual buildings, spaces, and facilities rather than considering the terms of urban planning. To complement the virtual space game with the aspects of urban planning, these games can encourage the participation capability and enhance the communication skills of citizens.

  • Mid of 1980s witnessed the beginning of a new trend regarding the elderly as the Third Age Group, which is capable of positive selection for their later life. These changes are caused not only by the rising cost of caring them as the dependent to the society, but also by paradigm shift from the clinical and biomedical model to political economy and critical gerontology. The paradigm shift is based on the social constructionism as a perspective on the later life. In this communication the development of social constructionism is reviewed as an approach on the living environment for later life through literature survey. Emphases were made on the anti-ageism instead of ageism in the analysis of the social constructionism perspective for living environment in later life. Individual practice, influencing the practice of others, influencing agency policy, and developing theory were addressed and emphasized for the practice of anti-ageism. This study found the importance of the development of the social constructionism perspective on the study and practice regarding living environment for ‘the Third Age’ in Korean situation.

  • The purpose of this study is to grasp the spatial characteristics and consciousness structure for The Third Place through the empirical research, focused on housewives as the survey who spend many times in neighborhood. The four types as the consciousness structure are deducted, Nature-oriented type, Unusual experience type, Solitude enjoyment type, and Originality-oriented type. And the spatial characteristics related to the four types are deducted as the followings: Nature-oriented type contains the spatial characteristics as Wild space, Speculative space, Dotty occupation space, and Green way. Unusual experience type contains as Rambling space, Dynamic sojourn space, and Theme-plex space. Solitude enjoyment type contains as Anonymous private space, Encircling space, and Religious space. Originality-oriented type contains as Chatter space, Self development space, and Community space between families. The results of this study represent six characteristics on the third place, advocated by Oldenburg, and show housewives' various needs and concrete examples for the Third place in city.

  • When anesthetics were added to a bacteriorhodopsin (bR) in the purple membranes, the 570 nm absorption band shifts to 480 nm. This anesthetic-induced spectroscopic change is reversible. The apparent pKa (6.3) of this equilibrium depends on the nature of the anesthetics in which bR is dispersed. The electric orientation measurements showed that the native bR is easily achieved by relatively small electric field which is oriented at $60^\circ$, while anesthetic-treated bR is not the case. These results demonstrate that the subtle changes in the chromophore and the protein structure surrounding the chromophore by anesthetics influence the spatial orientation of the charged residues in the protein matrix surrounding chromophore.

  • Background: Thoracoplasty has become a rarity in current clinical practice, although it has been widely employed for well over a century as a procedure for reducing the capacity of the thoracic cavity. Yet we have perform tailoring thoracoplasty following or concomitant with pulmonary resection in 20 patients. The aim of this study is to evaluate the early and late clinical results and also the significance of tailoring thoracoplasty. Material and Method: From March 1995 to June 2005, modified thoracoplasty following or concomitant with pulmonary resection was performed in 20 patients out of a total of 298 pulmonary resections for closing air leaks and for treating persistent pleural space following pulmonary resections, and to tailor the thoracic cavity to accept a diminished lung volume. Of the 20 patients, 14 patients had tailoring thoracoplasty performed concomitant with pulmonary resection, and the remaining 6 patients also had tailoring thoracoplasty performed following pulmonary resection. The subjects ages ranged from 24 to 77 (mean $59.1{\pm}6.4$) and a male preponderance was noted (17 : 3); the number of left and right surgeries was equal. The preoperative primary underlying diseases were lung cancer in 7 patients, pneumothorax with giant bullous change in 6 patients, bronchiectasis in 2 patients, previous pulmonary tuberculosis associated with aspergilloma in 2 patients, empyema with fibrothorax in 2 patients and multiple lung abscesses & destruction due to previous trauma in 1 patient. The operative methods were apicolysis and subperiosteal removal of the 2nd, 3rd and 4th ribs (the costochondral junction to the posterior portions of the ribs) with preservation of the first rib and compression of the anterior chest via cotton bags and elastic bandages. Result: The mean duration of the air leaks after thoracoplasty was $1.6{\pm}0.2$ days (range: $0{\sim}7$ days) and the mean duration of an indwelling chest tube was 7 days (range: $5{\sim}11$ days); the mean duration of hospitalization was $19.2{\pm}2.8$ days (range: $8{\sim}47$ days). The postoperative complications were wound infection (2) and pneumonia (2); reoperation was done due to bleeding (1) in one patient who underwent concomitant thoracoplasty and there was 1 case of wound infection (1) after postresection thoracoplasty. The mortality was 1 patient in the early phase and 4 patients in the late phase. Conclusion: We conclude that tailoring thoracoplasty may be performed to close anticipated persistent pleural spaces and to accommodate the diminished lung volume with acceptable cosmetic results when this procedure is combined with pulmonary resection in selected patients.

  • The café has become an important representative "third place" where people study and rest. Hence, it is worthwhile for researchers to understand the needs of individual users as well as the requirements of people who visit such venues in groups. The identification of strategies that can help achieve larger, wider, higher, or deeper interior spaces in small and compact locations can generate benefits for both users and designers. In this study, where 56 interior design students participated, we used an eye-tracker and images of cafes to explore the relationships between spatial depth and the intention to visit a cafe space. The researchers digitally developed fifteen different conditions of space and measured the eye movements of the participants using an eye-tracker when they examined images that appeared to convey the most depth. Participants were also asked to imagine the proposed space images as cafes and to select one of the 15 images as the location that they would be most likely to visit individually and one that they would frequent in the company of other people. The research results revealed that certain ways of using interior design elements altered the participants' perceptions of spatial depth without any change being effected to the actual volume or the size of the space. The participants tended to perceive a space with a small decorative artwork on a dark toned wall with unconnected furniture as deeper than a space with no or large artwork on a light toned wall with contiguous furniture. Spatial depth was a more important consideration for an individual visit than for a group visit. The results of this exploratory study will help scholarly understanding of the role played by spatial depth in customer intentions to visit a cafe.
