Purpose: Recently energy consumption is rapidly increasing due to continuous development of social evolution in various field. In this situation, there is a lot of effort to reduce this energy consumption in many ways, especially in building energy. Preceding studies already started to analyze the housing area such as zero energy house and passive house by researching annual building energy consumption, but to apply the results of housing to office building is insufficient since it has different consumption tendency. Method: In this study, eQuest program was used for simulation and the base model is selected among standard office building in ASHRAE 90.1. Variables are divided into passive and active factors for comparison. Result: In passive factors, glazing system showed the highest energy saving rate by 21.3% with triple low-e glass and enhancing wall u-value showed the lowest energy saving rate by 3.6% with 0.15 m2/K. In active factors, VAV system showed 30.9% energy saving rate when compared to CAV system, and heat exchanger showed 10.2% energy saving rate. For regeneration energy part, photovoltaic panel generated 10.4% of base annual energy usage.

The nursing-care insurance system started in April, 2000 in Japan. It was a kind of business opportunities for a lot of private entrepreneurs. They came into this care service business from another type of business rapidly. They opened the pay nursing homes with 24 hour nursing. However, the expense load of the nursing-care insurance system was large, local governments started controlling on total numbers of facilities with 24 hours nursing in 2006. So the group houses besides the pay nursing home without nursing care are paid to attention. The pay nursing home has been often managed by the nursing business. Most of the group houses are managed by community based NPO. This study is a case study by the visit and the interview form for one of the group houses. The group house "Shalom Tsukimino" in Kanagawa started operations comparatively at early time among them. Through the study we recognized that a lot of people were helping the NPO as a community service. So they can manage the group house and people who live there get the services with low cost. They show that they separate residence and nursing and use the community service efficiently. We can find a new direction in this case for the life in elderly.

The numbers of the elderly who suffer Empty Nest Syndrome have been accelerated as an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing houses into shared houses was set as a hypothetical solution in this study, and finding out the responses of the elderly who owns their own houses is the purpose of the study. A small workshop panel method was used and the elderly aged 55 years upwards took part and they own a detached house that is relatively large for the elderly or the elderly couple to live alone. The workshop was consisted of 3 stages: 1. a survey 2. an interview 3. a site visit. Through this, problems that the elderly have been experiencing within their houses were looked into and the responses of the elderly on converting their houses to shared houses by introducing developed schematic plans. As a result, positive responses from the house owners were carried out based on the fact that subsidies from the government on house renovation and tenants matching programs are supported. Shared houses could provide home owners economical support with rents and help them to feel less lonely. This is one way of supporting the elderly to live and age actively in their later lives. Therefore, this idea should be established in connection with preparing aging, aged, and super-aged society.

An active vibration control technique of a time-varying cantilever beam is proposed in this study. A simple in-house coil sensor instead of expensive commercial sensors was used to measure the vibrational displacement of the beam. Active band pass filters and artificial neutral net works detect the frequencies, amplitudes, and phases of the main vibration mode. The time constants of the low pass filter representing the positive position feedback controller are updated in real-time, which generates the control voltage input to actuate the piezoelectric actuator and suppress the vibration. An experiment was successfully performed to verify the algorithm for a cantilever beam, which fundamental natural frequency arbitrarily varies between 9 Hz ~ 18 Hz. The present active vibration suppression technique can be applied to variety of structures which undergoes large variation of dynamic characteristics while operating.

Current interest in ${\gamma}$-aminobutyric acid (GABA) has arisen from the convergence of several independent line of investigation leading to the demonstration that this and related substances are normal products of brain metabolism and that GABA has an important physiological action upon brain function as well as upon certain peripheral nervous structures. The interest for neurophysiologists has been enhanced by the importance of the discovery for the role of humoral mediator of synaptic transmission or regulator of neuronal activity in the central nervous system, particularly if it may shed some elight upon the nature of central inhibitory processes. In accordance with such an interest and importance, this work was performed in order to standardize the normal content as a preliminary investigation of so-called night active and daytime active animals GABA content in their brains when they are exposed to light and darkness. The method, through which the estimation has made in this work, was paper chromatographic method developed by Maynert and Klingman for the estimation of GABA content in animal tissues. The results obtained are summerized as follows: 1) GABA content in the cerebral cortex of house rat ranged from 90 to $310{\mu}g/gm$ of wet weight. 2) The content of GAGA ranging from 130 to $510{\mu}g/gm$ of wet weight was occurred from midbrain of the rat. 3) GABA content was ranged from 30 to $150 {\mu}g/gm$ of wet weight of the rat cerebellum. 4) The contents of fowl cerebral cortex, midbrain, and cerebellum are estimated as ranging 230-590, 250-620, $50-280{\mu}g/gm$ of wet weight, respectively. As a result, it may be concluded that among three brain tissues of both animals the midbrain is the highest region in GABA content. Fowl brain, on the other side, contains more higher GABA content than the house rat brain does.

This study aims to understand the consumer consciousness of the interior design by experiencing the interior space of the model house provided by the construction company. For this, the author investigated the spatial images about the apartment interior design and the satisfaction level depending on the experiential elements. Survey questionnaires were distributed to people who visited six model houses. Subjects were asked about the experience about the interior space of the model house. Their response to the experiential elements was analyzed with 5-point Likert scale and was computed as frequencies, percentages, and means. For the spatial image characteristics, adjectives were substituted for the image scales. As a result, the author found out the following: First, the interior space was commonly directed to the soft image, which was mixed with modern, noble, decent, dynamic and natural styles depending on the companies. The trend of each interior design basically had static, soft and vague images, and partially had two kinds of tendencies: the one was mild and natural, and the other was modern and elegant. Second, as the strategic modules of the experiential marketing, five experiential elements were investigated to find the satisfaction level through the model house interior space. The emotional element got the highest point followed by the cognitive element and the active element, while the sensible element and the relative element got the lowest point. Third, consumer response was generally positive toward the model house interior design provided by the construction company. It is necessary to make up for the design that can give an aesthetic pleasure with familiar images, rather than give a firm recognition about the design.
