  • Atanassov introduced the irrational factor function and the strong restrictive factor function, which he defined as $I(n)=\displaystyle\prod_{p^{\alpha}||n}^{}p^{1/{\alpha}}$ and $R(n)=\displaystyle\prod_{p^{\alpha}||n}^{}p^{{\alpha}-1}$ in [2] and [3]. Various properties of these functions have been investigated by Alkan, Ledoan, Panaitopol, and the authors. In the prequel, we expanded these functions to a class of elements of $PSL_2(\mathbb{Z})$, and studied some of the properties of these maps. In the present paper we generalize the previous work by introducing real moments and considering a larger class of maps. This allows us to explore new properties of these arithmetic functions.

  • In Korea, the driving system restriction criteria is strictly applied(gross weight 400kN, axial load 100kN). Especially after the Seoungsu Bridge accident, safety factor has been strictly applied. The Safety factor is applied to the cumulative results for each steps like design, construction, maintenance of the Bridge. Because of it, the bridge is undervalued compared to its capacity. So, this generates loss for both private and military sector(eg. logistical delays, structural damage, etc.). But analyzing data from many existing researches we have confirmed that the military heavy vehicle may pass through the first class bridges. In consequence, this study have focused on determining whether HETS vehicles can pass over the first class bridge, without safety issues, using MIDAS structural analysis program. The results have confirmed that the military heavy vehicle may pass over the bridge.

  • 본 연구에서는 중학교 학생들이 체육수업에서 느끼는 걱정거리 수준을 혼성학급과 동성학급으로 구분하여 걱정거리의 하위 요인별 차이를 심층적으로 분석하여 융복합적 교육 방안을 탐색하는데 목적을 두었다. 연구대상은 경기도에 위치한 중학교 6개교를 무선적으로 선정하여 554명의 학생을 대상으로 하였다. 학급별, 학년별, 학업성적별, 체력등급별에 따른 걱정거리 하위 요인과의 관계를 파악하기 위하여 다변량분산분석 모형을 설정하여 실시하였다. 연구를 통해 얻어진 결과는 다음과 같다. 첫째, 중학교 체육수업에서 느끼는 걱정거리 수준은 학급별(혼성, 동성)에서 '처벌' 요인에 많은 영향을 미치는 것으로 예측되었다. 둘째, 중학교 체육수업에서 느끼는 걱정거리 수준은 학년별에서 '운동종목에 대한 걱정'과 '수업 중 마찰' 요인에 많은 영향을 미치는 것으로 예측되었다. 셋째, 중학교 체육성적별 학생들이 체육수업에서 느끼는 걱정거리 수준은 차이를 나타내지 않는 것으로 나타났다. 넷째, 중학교 체육수업에서 느끼는 걱정거리 수준은 체력등급별에서 '운동종목'에 대한 걱정 요인에 많은 영향을 미치는 것으로 예측되었다.

  • The purpose of this study was to categorize lifestyle patterns and to define the characteristics of the lifestyle of middle class residents in Seoul. Questionnaires were administered to 1572 homemakers in Seoul. Statistics with the SPSS software package for factor analysis and F-test was used. The results showed that the type of car which the residents owned was a major indicator to classify SEC(Socio Economic Class). The middle class was categorized into four groups which were relevant classifications based on determining indicators obtained from previous studies: the lower middle class which owned a Tico was classified into the Economy Concerned Lifestyle category the middle class which owned an Elantra was classified into the Health Concerned and Hobby Oriented Lifestyle category the upper middle calss which owned a Sonata was classified into the Interior Design and fashion Oriented Lifestyle category and the lower upper class which owned a Grandeur was classified into the Hobby and Fashion oriented Lifestyle category.

  • The not an organization a branch stream the maintenance factor class on a class and the roadway type for roadway lighting design, the facted an insufficiency maintenance factor to apply our the country conditions. The consideration of maintenance factors is not being fully applied for roadway lighting design in Korea. This paper consider optical characteristics and maintenance factors as well as LID of Luminaires in designing roadway lighting. Consideration of maintenance factors that are neme specified according to LDD(Luminaire Dirt Depreciation), LLD(Lamp Lumen Depreciation), AADT(Average Annual Daily Traffic) based on IESNA regulation. The analyzed optical characteristics are applied for stagger and cross roadway types with maintenance factors in the range of 0.51$\sim$1.00 and equipment factor of 0.9.

  • Elementary School is a special facility where sense of place plays critical role for the development of children. Children in special education call for special attention as they hold inferior status compared to the children in regular class especially under the inclusive education policy. Eight cases of special education class area are analyzed in terms of social space, personal space and favorite place which is known to be basic factor for the development. As a result outdoor space found to be designed inappropriate even when designed accessible to the special education class as it could not meet the developmental needs of children in special education. Special education class area inside the building is also found to be too exclusive to allow social mix with children in regular class disregarding the intention of inclusive education. Location of these class should be strategic as it is critical to be linked with regular classroom efficiently still allowing psychological buffer as the children in special education tend to form restorative space inside the special education classroom showing the possibility of creating sense of place there.

  • This study analyzed the differences in value perception and purchasing intention for natural cosmetics by LOHAS class and investigated what influences people's value perception for natural cosmetics had on their purchasing intention. Total 450 questionnaires were distributed to adults of over 20s to 50s for the period from Dec. 1, 2011 to Dec. 14 and 410 questionnaires were used as analysis data. As for collected data, the statistical package SPSS 18.0 Version was used for factor analysis, frequency analysis, reliability test, one-way ANOVA, Chi-Square test, Scheffe-test, correlations analysis and multiple regression analysis. LOHAS class was divided into three groups (higher, middle and lower) based on LOHAS index. Through factor analysis, the value perception for natural cosmetics were divided into three factors (social value, emotional and functional value perception). The results of this study were obtained as below. First, in case of the value perception for natural cosmetics by LOHAS class, it was demonstrated that the higher LOHAS classes they were, the higher value perception for natural cosmetics (social, emotional and functional value perception) they had. Second, in case of the effects of the value perception for natural cosmetics by LOHAS class on their purchasing intention (intention to use and recommendation of usage), it was found that their value perception influenced their purchasing intention. Social value perception and functional value perception, especially social value perception largely affected the purchasing intention of all LOHAS classes, while emotional value perception didn't affected the purchasing intention.

  • The purpose of this study is to identify the differences in persuasive effectiveness of visual merchandising according to merchandise class. For the experiment, 8 stimuli brands were selected. A total of 360 questionnaires were obtained from college students. The results were as follows. First, VM cognition were divided into 3 factors by confirmatory factor analysis: coordination, attractiveness, and function. Second, coordination and function had a positive effect on brand attitude. Third, brand attitude had a positive impact on brand loyalty. Fourth, it was revealed that merchandise class had a moderating role in the influence of VM cognition on brand attitude. This study has a meaning in that the theoretical extension of previous studies on VM was executed and demonstrated the moderating role of merchandise class when brand attitude was formed by VM cognition.
