We have developed an optimization algorithm based formulation for performing efficient time driven simultaneous place and route for FPGAS. Field programmable gate array(FPGAS) provide of drastically reducing the turn-around time for digital ICs, with a relatively small degradation in performance. For a variety of application specific Integrated circuit application, where time-to-market is most critical and the performance requirement do not mandate a custom or semicustom approach, FPGAS are an increasingly popular alternative. This has prompted a substantial amount of specialized synthesis and layout research focused on maximizing density, minimizing delay, and minimizing design time.

Museum in each era and society has its own specific meaning. When a museum is viewed from a cultural perspective, it may be apprehended as more than a functional tool for it also represents the culture of that particular time. The role of museum made across each stages are not simply shifts in architectural style, but indicate an evolution in social role and intrinsic function. The purpose of this study is to comprehend the definition of museum and the variety of exhibition design from the ancient days which the term is called 'museum' is used for the first time to beginning of the 20th century. As a result of this study, we can find that the museum is considered the meaning of the place to change according to the social environment more than the place to the collection, conservation, exhibition, education from the beginning. Accordingly, museums should make continued efforts to set cultural guidelines for the general public.

A church architecture which has an important meaning as a place which is for worship God, relationship, education, evangelism, service and formative meaning that express as a specific form. It has been changed by age or changes of theology, also its structure and form has been changed so as to change of a rutual. the church architecture that has been authorized as a architecture which is a representation of the age does not represent the age and it has weaknesses for expression of unique identification church has. Also, because it is lacking thoughts about regional viewpoint, it loses the characteristic of regional "landmark" like the past. In addition, a place of worship has been changed materiality of space like auditorium or seats so as to change of consciousness of worship, and it is exposed problems of expression of identification. Therefore the church architecture of twenty first centry needs to holy and be able to deliver their new standards and needs that fit original purpose of church for users.

This research proposes the composition logic of an Active Learning Environment (ALE), to enable discovery by learning through experience, whilst increasing knowledge about modern architectural heritage. Linking information to the historical heritage using Information and Communication Technology (ICT) helps to overcome the limits of previous learning methods, by providing rich learning resources on site. Existing field trips of cultural heritages are created to impart limited experience content from web resources, or receive content at a specific place through humanities Geographic Information System (GIS). Therefore, on the basis of the blended space theory, an augmented space experience method for overcoming these shortages was composed. An ALE space framework is proposed to enable discovery through learning in an expanded space. The operation of ALE space is needed to create full coordination, such as a Content Management System (CMS). It involves a relation network to provide knowledge to the rule engine of the CMS. The application is represented with the Deoksugung Palace Seokjojeon hall example, by describing a user experience scenario.

Today most landscape architects and scientists have approached ecological restoration, only in a scientific way or on aesthetic way so as to deal with the complex phenomena of a site easily. However, 'the real world' as well as 'ecological nature' as it is can not be totally dealt by the scientific approach which is quantitative and reductioinal. ince a site to be restored has the character of 'place' where man 'dwells', it must be designed and built as total phenomenon. In terms of Martin Heidegger's interpretation of "revealing", we might find out how to overcome the dilemma of the 'modern technology'. To the point of the phenomenological integrity between 'modern technology' and 'art', we can reveal 'sense of place' on a site. The phenomenological approach, which is related to the characteristics of the site, implies something more than scientific since it focuses on the development of site-specific data without wasting extra data for ecological restoration. Bodily experiencing a site with the perception, man discloses the site's nature and he also analyzes it in a scientific way. Therefore the phenomenological approach might be a clue of constructing ecological restoration as well as construing the identity of landscape architecture.

Virtual reality technology can be defined as human-computer interface that makes virtual place of specific environments or situation is an interactive computer-generated experience taking place within a simulated environment. In order to combine virtual reality technology of domestic nuclear power industry, the R&D Project has been developing a virtual/augment reality system for nuclear power plant from April 2018 to March 2021. To effectively apply virtual reality technology of domestic nuclear industry, it is necessary to build virtual space similar to real environment. Therefore, This study is analysed 3d model status for nuclear power plant during the life-cycle, and suggested a method to build 3D cad model close to real environment.

This study focuses on the asymmetrical realization of homorganic nasal-obstruent stop clusters in English when they occur word medially and word finally. This uneven realization of NC clusters is not only controlled by the place of articulation of the cluster constituents but also by the agreement of voicing feature specifications of the cluster elements. We propose context-sensitive constraints, which are more specified versions than *NC (Pater, 1996, 1999, 2004). The result of the study reveals that homorganic NC clusters consisting of coronal place feature are faithfully realized word finally while they are constrained word medially. The deletion of voiceless post-nasal coronal stop should be considered a new language specific strategy to avoid *NC.

The difference of sex has been an object of interest and argument in medical, psychological, social, and cognitive science fields. This study started from the question of to what extent does the difference of sex have effect on successful interior design. In strive of resolving this, an experimentation of preference in terms of cafe interior design was performed with methods of human sensibility ergonomics. As the result, the difference of sex in preference regarding calf interior design could be observed. Males have main interest in the intensity of luminance, i.e. the brightness, whereas females attach importance to both qualify of light and color. In addition, there is a tendency for males to see cafe as a public place while females recognize cafe as a place for entertainment. Taking the result of this study into consideration can lead to successful gender specific cafe interior design.

Ameliorating mechanisms of red ginseng on learning deficits were investigated in the following 3 experiments; its effects on 1) place learning deficits in aged rats and in young rats with selective hippocampal lesions (behavioral study), 2) long-term potentiation in the hippocampal formation (neuro- physiological study), and 3) ChAT (choline acetyl transferase) activity in various brain regions of aged rats (pharmacological study). In the behavioral study, first, performance in the place learning tasks were compared among 3 groups of young and aged rats; control young intact rats (10-12 week old) treated with water, aged rats (28-32 month old) treated with water, and aged rats (28-32 month old) treated with red ginseng (100 mghglday) suspended in water. Second, performance in the place learning tasks was compared among 3 groups of young rats; control intact rats treated with water, rats with bilateral hippocampal lesions treated with water, and rats with bilateral hippocampal lesions treated with red ginseng (100 mg/kg/day). Each rat in these 2 behavioral experiments was tested with the 3 types of the place learning tasks in a circular open field using intracranial self-stimulation (ICSS) as reward. The ICSS reward was delivered if the rat (1) moved distance of 100-160 cm (DMT): (2) entered an experiment-determined reward place within the open field, and this place was randomly varied in sequential trials (RRPST); or (3) entered 2 specific places, and did a shuttle behavior between the 2 places (PLT). Performance of the aged rats in the ginseng group was not significantly different from that of control young rats in ICSS (current intensity, bar press rates), DMT and RRPST. However, treatment with red ginseng significantly ameliorated place-navigation learning deficits in aged rats in the PLT. Similarly, red ginseng ameliorated learning and memory deficits in young rats with hippocampal lesions in the same tasks. In the neurophysiological study using young rats, perfusion of hippocampal slices with non-sapon in fraction of red ginseng significantly enhanced magnitudes of the long-term potentiation (LfP) in the CA3 subfield. In the pharmacological study, treatment with red ginseng did not affect ChAT activity in aged rat brain including the hippocampal formation. These results strongly suggest that red ginseng ameliorates learning and memory deficits in aged rats through actions on the CA3 subfield of the hippocampal formation, which were independent of the presynaptic components of the cholinergic system
