The objectives of this study were to investigate the perceptions of Korean female university students for clothing pattern tendency and structural element of clothing pattern image dimension and to find how individual personality type influence the preferred clothing pattern characteristics. For this study, a questionnaire was designed and sent to 600 female university students of Daejeon, Seoul and metropolitan area. The tool used in this study was MBTI(The Myers-Briggs Type Indicator) Form G Korean version and for the analysis of data SPSS 10.0 package were used. 10 representative patterns for this study were floral, dot, stripe, check, animal, abstract & artistic, geometric, vegetable & leaf, paisely, patchwork pattern. The data were analyzed by factor analysis, arithmetic mean, One-Way ANOVA, x²-test. The major findings were as follows: Clothing pattern image dimension perceived by Korean female university students for 10 representative patterns were basic form, deluxe, specialty, and cultural dimension. Among them, basic form and deluxe dimension were major dimensions. In basic form dimension, dot pattern score was high indicating female students perceive it as light, comfortable, clean, cool and simple pattern image. In deluxe dimension, floral pattern scored high and in specialty dimension, abstract and artistic pattern scored high among other pattern image. In cultural dimension, geometric pattern and check pattern scored high. Based on other detailed analysis results, It is concluded that the personality type greatly influence clothing pattern evaluation. For example, in case of color combination of patchwork pattern, there was a difference in color preference depend on a personality type such as sensing(S) or intuition(N). Therefore, sensing personality type preferred adjacent color combination than contrast color combination. Detailed marketing strategy is necessary in planning textile design of merchandise plan.

This study is on the sensitive image of pattern expressed in the color & formative types of traditional Jokakbo(scraps of cloth). The object of this research is Korean traditional scraps of cloth in the latter period of Chosun Dynasty. This study is to be classified into 10 formative types like square type 1, square type 2, diagonal type, diamond type, many color striped type, concentric circle type, pinwheel type, vertical line type, cintamani pattern type, and free style type to apply the design of Jokakbo to Korean design. And color group is divided into vivid tone and pale tone. And it constitutes 17 patterns from the combination of these two types. As for the factors of constitution of scraps of cloth, it consists of factors like revelation, attraction, temperature sense, abstract, and rigidity. In the emotional image in the patterns, both vivid tone and pale tone showed dynamic and warm emotion together. Also, the factors of revelation and attraction were evaluated as opposite images, and it evaluated the plain and dim emotion as more attractive emotion. They preferred the pale tone to the vivid tone. They preferred the cintamani pattern in the vivid tone, and the diamond pattern in the pale tone most. From the research result above, this study made the abstract image of scraps of cloth standardized and prepared for a basis to execute it essentially. This research will be used as basic data to make traditional Korean image spotlighted in the world fashion markets as well as it will be helpful to the development of pattern design for the scraps of cloth essentially.

Abstraction is an important concept applied widely to variables, functions, complex data, abstract data types, classes and polymorphism in programming languages. However, the concept of abstraction has been considered as ambiguous and explained differently because it is not defined clearly and uniformly. In this paper, we analyse many aspects of abstraction in programming languages, and propose the taxonomy of abstraction. We classify abstraction according to the mechanism of formation into 4 categories such as napping abstraction, bundling abstraction. integrating abstraction and extending abstraction. We also consider many concepts related closely to abstraction such as functions, abstract data types, objects, encapsulation and classes in the view of abstraction. These analysis and consideration will make it possible to explain uniformly various aspects of abstraction which have been treated individually and differently, and to understand the meanings, necessity and importance of abstraction more intensively.

Recently, hospital architecture has acknowledged remedial value of environment and atmosphere, which consider patient's statement of physical, spiritual, psychological and social focus, escape from the past focus of functional and rational space composition. The many research of hospital architecture just analyze elements of architectural planing which focus how to make a healing environment for patients. The purpose of this study is to abstract the design principle of architectural space composition for healing environment significance, through case study which follow up space composition. To abstract healing environment significance by space composition, each case study hospitals should be analyzed and estimated on the spatial composition elements. It is to provide the basic data for effective architectural planning of the hospital.

Purpose: The purpose of this study was to analyze nursing students' learning styles and relationship of learning style to participation and academic achievement. Method: The study participants were nursing students in C college learning through problem based learning (PBL). Data were collected using a questionnaire which included Kolb's learning styles. Performance evaluation and paper examination were used to evaluate academic achievement. Results: Most of the students had converger type learning style. Student with a tendency to abstract conceptualization, such as converger type and assimilator type, preferred discussion and presentation. The students with converger type learning style participated and achieved better than students with diverger style. Conclusion: The results indicate that learning style was related to participation and academic achievement. Therefore in order to use PBL effectively, facilitators should consider students' learning styles.

Currently, there is no definitive regulation for the appropriate frequency of data sampling in water distribution networks, yet it plays a crucial role in the efficient operation of these systems. This study proposes a new methodology for determining the optimal frequency of data acquisition in water distribution networks. Based on the decomposition of signals using harmonic series, this methodology has been validated using actual data from water distribution networks. By analyzing 12 types of data collected from two points, it was demonstrated that utilizing the factors and cumulative periodograms of harmonic series enables similar accuracy at lower data acquisition frequencies compared to the original signals.

Abstract: A minimum commitment method(MCM) was applied to predict the long-term creep rupture life for type 316LN stainless steel(SS). Lots of the creep-rupture data for the type 316LN SS were collected through world-wide literature surveys and the experimental data of KAERI. Using these data, the long-term creep rupture life above ${10}^5$ hour was predicted by means of the MCM. In order to obtain the most appropriate value for the constant A being used in the MCM equation, trial and error method was used for the wide ranges from -0.12 to 0.12, and the best value was determined by using the coefficient of determination, $R^2$ which is a statistical parameter. A suitable value for the A in type 316LN stainless steel was found to be at -0.02 ~ -0.05 ranges. It is considered that the MCM will be superior in creep-life prediction to commonly-used timetemperature parametric method, because the P(T) and G($\sigma$) functions are determined from the regression method based on experimental data.

Abstract This study was conducted to pursue the normalization of frequency distribution by making an approach to the coefficient of skewness to nearly zero through the Box-Cox transformation, to get probable flood flows can be calculated by means of the transformation equation which has been derivated by Box-Cox transformation in the annual maximum series of the applied watersheds. It has been concluded that Box-Cox transfromation is proved to be more efficient than logarithmic, square root and SMEMAX transformation which is based on the trigonometric solution of a right triangle whose three verteces repesent the smallest, median and largest observed values of a population in making the coefficient of skewness nearer to zero. Consequently it is shown that probable flood flows according to the return period based on Box-Cox transformation are closer to the observed data as compared to other methods including SMEMAX transformation and fitted probability distributions such as the three parameter lognormal and the type I extremal distribution for the applied watersheds.
