Purpose: The purpose of this study was to compare health promoting behavior between working and non-working mothers with infants and toddlers, and to investigate factors affecting the mothers'health promoting behavior. Methods: This descriptive study was conducted through conveniently sampled 403 women who visited the child health clinics at two public health centers. The questionnaire included the Health Promoting Life Style Profile (HPLP) and a visual analogue scale for subjective health status. ANCOVA, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted using SPSS ver. 21. Results: Working mothers' average HPLP score ($2.30{\pm}0.37$) was higher than non-working mother's ($2.15{\pm}0.37$). The score of the physical activity subscale was lowest among the subscales and there was a difference between the two groups. Subjective mental health status was the only predictor of working mothers'health promoting behavior, and it explained 23.2% of variance in health promoting behavior. Subjective mental health status, education, and age were the predictors of non-working mothers' health promoting behavior and they explained 27.2% of variance in health promoting behavior. Conclusion: According to the findings, both working and non-working mothers' health promoting behaviors were low. To promote mothers' health, it is necessary to develop diverse community health promotion programs to support mothers.

The aim of this study is to deduce color temperature and illuminance by conducting the preference & affective evaluation consequent on illuminance change of ambient light in case of the lighting method of ambient light mixed with task light in time of reading which is visual work action among the action in learning space. As a result of the prior survey on preferred lighting method in time of the act of reading targeting 20 experts before doing evaluation, the method of lighting mixed with ambient light and task light was found to be the highest. Such a result is analyzed to be attributable to the fact that the less the difference in illuminance of nearby space and work surface because of the mixed method of lighting, the less the glare, which makes a reader feels easy and concentrate on reading. On the basis of descriptive statistics of evaluation results and impact analysis by category, this study recommends the application of combinations of ambient light illuminance ranging from 40lx to 100lx with color temperature of 5500~6000K in case of the method of lighting mixed with general light and task light.

In considering the relationship between natural beauty and the human frame of mind, or the interconnections between the Landscape and the point of view, we are concerned primaily with the external factors. Historically, certain physical features tended to cause shifts in human attitudes toward landscapes; We concentrate on this phenomenon of changeful scenery rather than on what psychological factors caused certain landscapes to be regarded as remarkable or unique. In a similar fashion we must ask ourselves what the basic elements in landscape are and attempt to ascertain their visual and spatial characteristics before we attempt to desingn environments that are fundamentally, physical in character. Futhermore, the experience of meanings, a part of literatual association process, appeared through the intension of nature study looking for the best landscape phenomena out of simple naturelooking. Of course, as the variable degree of landscapes changes, the dualistic relationship between humans and objects shows the different experience of meanings as the time changes even in landscapes which possess variable factors in same season. The study is conducted by defining the nature of recognizing and appreciating the logical structure of the concept "Landscape" after analysis of meaning context appeared in 'Kyung' which is consists of time, space and elements in landscape.

This thesis presents an emotion-based contents player platform that can change its visual and aural components as user's emotions. It analyzes the emotion as pleasant, unpleasant, aroused, and relaxed based on the physiological signals and the user's active response. Accordingly. the system reorganizes graphical and aural stimuli, such as, light, color, sound, in real-time. It can be used to develop and show the emotional contents and also be applied for the systematic analysis to find out how the components would affect the emotion. This paper describes overall the system architecture and the implementations of the sub-systems, as well as the actual contents built on top of the platform.

The widespreading of XML as a standard for semi-structured documents on the Web opens up challenging opportunities for Web query language. And UML is a graphical language to represent the result of object-oriented analysis and design. In this paper, we introduce an UML-based graphical query language for XML documents. The use of a visual formalism for representing the syntax and semantics of queries enables an intuitive expression of queries, even when they are rather complex. And, it is matched a series of processes to store and retrieve XML documents to OODBMS with the use of an uniform visualization for representing both the content of XML documents (and of their DTD) and the syntax and semantics of queries.

In this study, we propose a low voltage stress and cost-effective light emitting diode (LED) driver capable of multi-channel current balancing. Conventional LED drivers require as many boost converters as the number of LED channels, whereas the proposed LED driver requires only one buck converter and several balancing capacitors instead of several expensive boost converters. Additionally, while the components of the boost converter have high voltage stress and depend on the LED driving voltage, components of the proposed driver have about one-half of the voltage stress across all components. The proposed driver exhibits high reliability and cost effectiveness because it only uses few DC blocking capacitors with no additional active devices to balance the current of multi-channel LEDs. The proposed driver exhibits high reliability and cost effectiveness. The validity of the proposed driver is confirmed through a theoretical analysis. An explanation of the design considerations and experimental results were obtained using a prototype applicable to a 46" LED-TV.

In this study we propose an automatic reading system for diagnostic DNA chips. We define a general specification for an automatic reading system and propose a possible implementation method. The proposed system performs the whole reading process automatically without any user intervention, covering image acquisition, image analysis, and report generation. We applied the system for the automatic report generation of a commercialized DNA chip for cervical cancer detection. The fluorescence image of the hybridization result was acquired with a $GenePix^{TM}$ scanner using its library running in HTML pages. The processing of the acquired image and the report generation were executed by a component object module programmed with Microsoft Visual C++ 6.0. To generate the report document, we made an HWP 2002 document template with marker strings that were supposed to be searched and replaced with the corresponding information such as patient information and diagnosis results. The proposed system generates the report document by reading the template and changing the marker strings with the resultant contents. The system is expected to facilitate the usage of a diagnostic DNA chip for mass screening by the automation of a conventional manual reading process, shortening its processing time, and quantifying the reading criteria.

Recently, brick walls are being widely introduced in rural areas. Walls are a very important design element of space. However, most brick wall works do not consider the human psychological characteristics. The purpose of this study was to investigate psychological characteristics on brick wall bonds such as the stack bond, running bond, english bond, flemish bond, america bond. The results of the research can be summarized as follows: 1)There is no statistical difference of psychological evaluation results among student groups using the semantic differential scale method using 10 adjectives. 2)Stack bonds have an uninspiring, artificial, simple, restful, boring and ordered psychological characteristic. Running bonds have an uninspiring, restful and ordered psychological characteristic. America bonds have a unique and modernistic psychological characteristic. English bonds have a unique, modernistic, complex and chaotic psychological characteristic. Flemish bonds have no critical psychological characteristics. 3)The running bond earned the highest score in preference, while the stack bond scored the lowest. Employment of brick wall bonds on this study was not highly preferred, hence it is necessary to develop a new brick wall bond design. 4)In conclusion, the proper selection of brick wall bonds is very important and we should consider human psychological characteristics in the design of rural areas.
