The major users of children's library are children and housewives. Recent increasing frequency of their visit to the library expands the function of it from the place where they borrow and read books further to the cultural space where each family unit can enjoy leisure activities. Though the children's library basically is a quiet place for reading books, peers' establishing friendship and emotional bond with the parents, and such plays as small scale muscular movements take place in addition to reading activities because the major users are infants under six or children in the lower grades in elementary school. Thus, in order to study the features and requirements that are inherent in the various behaviors of the children who use furniture, understanding of the particular factors in the physical environment of the children's library and the user context must precede. In reality, though the fixed form of the desks and chairs in the library was made by a small number of designers, a large number of children are using them in tremendously various ways beyond the ways that the designers had intended, adapting themselves to the environmental context. Therefore, the purpose of this study is to find out the children's using way of seats when they do reading and playing activities based on the way of interaction between children and parents, and, after modeling of the children's behavior data, to understand the demands inherent inside the various behaviors of children who use furniture.

Data quality issue in information systems is analyzed with focus on conceptual data modeling. Extensive investigation through triangulation of case studies is attempted to find how much extent inappropriate data modeling practices exercised in real workplace environment. It is revealed that more than 40 percent of data adversely contributed to unnecessary data redundancy, i.e., the level of data obesity is over 40 percent. Another contribution of this paper lies in excavation of all the categories of inappropriate data modeling practices, which has been previously only partially uncovered in the literature. New findings in this paper prove that the extent of inappropriate modeling is more serious that previously reported.

The introduction of tracer gas techniques to ventilation studies in indoor environments provides valuable information that used to be unattainable from conventional testing environments. Data acquisition systems (DASs) containing analogue-to-digital (A/D) converters are usually used to function the key role that records signals to storage in digital format. In the testing process, there exist a number of components in the measuring equipment which may produce system-based inference to the monitored results. These unwanted fluctuations may cause significant error in data analysis, especially when non-linear algorithms are involved. In this study, a pre-processor is developed and applied to separate the unwanted fluctuations (noise or interference) in raw measurements and to reduce the uncertainty in the measurement. Moving average, notch filter, FIR (Finite Impulse Response) filters, and IIR (Infinite Impulse Response) filters are designed and applied to collect the desired information from the raw measurements. Tracer gas concentrations are monitored during leakage and ventilation tests in the model test room. The signal analysis functions are introduced to carry out the digital signal processing (DSP) work. Overall the FIR filters process the $CO_2$ measurement properly for ventilation rate and mean age of air calculations. It is found that, the Kaiser filter was the most applicable digital filter for pre-processing the tracer gas measurements. Although the IIR filters help to reduce the random noise in the data, they cause considerable changes to the filtered data, which is not desirable.

In order to solve the current shortage of parking spaces, and redesign the main gate area of the U University, the research investigated some cases of other schools located in Seoul which actively constructed multi-purpose building structures. Those schools are considered to be good samples showing their efforts to fulfill the needs of more parking spaces in their campuses, and to cover with the growing needs of multi-functioned facilities accommodating services of academic affairs, reading room spaces, and amenities. With the investigation, the research finded out the current trends of campus developments from the sample schools, such as underground parking facilities connected with multi-purpose buildings along the main arteries of campuses. Following the trends the research thoroughly examined the present conditions of our school and tried to make some possible alternatives for the facilities. Under the conditions, the research suggested 1)to construct underground parking lots accepting around 1,000 cars under the ivory tower square located in front of University Administration Building, 2)to develop a big-scaled open square at the university main gate, and 3)to build a multi-purpose structure along the main street of the campus, which included administration services, studying spaces, and some commercial facilities.

The environment refers to what is surrounded by something during human life. This environment is related to the way humans live, and presents various problems on how to perceive the surrounding environment and how the behaviors that constitute the environment support the elements necessary for human life. Humans have an interest in the supportability of the environment as the interrelationship increases as humans perceive and understand the environment and accept the factors supported by the environment. In space, human movement starts from one space to the next and exchanges stimuli and reactions with the environment until reaching a target point. These human movements start with subjective judgment and during gait movement, the spatial environment surrounding humans becomes a collection of information necessary for humans and gives stimulation. will do. In this process, in particular, humans move along the movement path through movement in space and go through displacement perception and psychological changes, and recognize a series of spatial continuity. An image of thinking is formed[1]. In this process, spatial experience is perceived through the process of filtering by the senses in the real space, and the result of cognition is added through the process of subjective change accompanied by memory and knowledge, resulting in human movement. As such, the spatial search behavior begins with a series of perceptual and cognitive behaviors that arise in the process of human beings trying to read meaning from objects in the environment. Here, cognition includes the psychological process of sorting out and judging what the information is in the process of reading the meaning of the external environment, conditions, and material composition, and perception is the process of accepting information as the first step. It can be said to be the cognitive ability to read the meaning of the environment given to humans. Therefore, if we can grasp the perception of space while moving and human behavior as a response to perception, it will be possible to predict how to grasp it from a human point of view in a space that does not exist. Modern people have the theme of reminiscing dog-friendly hotels for the healing of petloss syndrome, and this thesis attempts to approach the life of companions.

Pseudomonas fluorescens B16 is a plant glowth-prornoting rhizobacterium, which produces an antibacterial compound that is effective against plant root pathogens, such as Agrobacrerium tumefaciens and Raistonia solanacearum. We mutagenized the strain B16 with Omegon-Km and isolated six antibacterial-activity-deficient mutants. Two cosmid clones that hybridized with the mutant clones also were isolated from a genomic library of tile parent strain. Using deletion and complementation analyses, it was found that the biosynthesis genes resided in a 4.3-kb SalI-NarI fragment. When a plasmid clone carrying the fragment was introduced into P. fluorescens strain 1855.344, which does not exhibit any antibacterial activity, the transconjugants exhibited antibacterial activity, indicating that the plasmid clone carried all the genes essential for production of the antibacterial compound. DNA sequence analysis of the fragment identified four putative open reading frames (ORFs): orf1 through orf4 The deduced amino acid sequences of ORF1, ORF2, and ORF4 were similar to cystathionine gamma lyase, pyruvate formate-lyase activating enzyme, and transcriptional regulator, respectively, yet the amino acid sequence of ORF3 showed no similarities to any known proteins. It was also demonstrated that the antibacterial activity was responsible for biological control of the bacterial wilt caused by R. solanacearum.

This study investigates the operation status of Special Schools' School Library and suggests policy implications after comparing with the School Library. As a result of the study, compared with general schools by region and school establishment, special schools are lacking in collection, budget, reading seats and usage. The number of collections per student in special schools is 57.9, the number of loans is 10.8, while the number of general schools is 96.7 and 29.6. The budget is about 30% of general schools, more than 90% of general schools have more than 20 seats, while Special Schools are only 75 (42.9%). There is not one volume of use compared to the collection. There are 47 schools (26.8%) with specialized staff, and only 20 schools have librarian licenses. Therefore, in order to revitalize the school library of special schools, it is necessary to cooperate with related organizations with disabilities in the local community, to expand collections, to have professional librarians and to improve the facilities environment.
