  • We analyze the problems of curriculum management and accreditation criteria through data analysis and survey on domestic and foreign curriculums and accreditation criteria, propose an efficient curriculum model based on educational realities and requirements of all university members and suggest improvement direction for more efficient curriculum management and accreditation criteria. For this study, we investigate curriculum data of several domestic and foreign universities, analyze the datum in various aspects and conduct a survey on curriculum management and accreditation criteria for collecting extensive opinion of university members on curriculum management and accreditation criteria. We expect that the proposed curriculum model and improvement direction of curriculum and accreditation criteria will help university members to efficiently manage accreditation programs.

  • Understanding of the hydraulics of flow over vegetation is very important to support the management of fluvial processes. The objective of this study is to assess the effects of hydraulic influence by tree planting in a compound channel with vegetated floodplain. This study analyzes the influence of tree planting on hydraulic features in Young-river in Munkyung city using HEC-RAS and RMA-2 model. The study results showed that there is a rise in water surface elevation and decrease in velocity near vegetated area. It is also ascertained that only negligible effects was seen within the feasible range of freeboard for the existing levees. However, as hydraulic features can vary depending on the aspect of flood inundation during each flood period, it is necessary to accumulate data through continuous data collecting.

  • Knowledge of the detailed solar radiation components are essential for modeling many solar systems. This is particularly the case for applications that concentrate the incident energy to attain high photo-dynamic efficiency achievable only at the higher intensities. In order to estimate the performance of concentrating solar systems, it is necessary to know the intensity of the beam radiation, as only this component can be concentrated. The Korea Institute of Energy Research(KIER) has began collecting detailed solar radiation component data since August, 1988. KIER's component data will be extensively used by solar system users or designers as well as by research institutes.

  • The purpose of this study is to clarify the cognitive complexity of clothing attributes, which influence the preference and purchase intentions. The subjects of this study are 434 female college students and formal survey methodologies were used for collecting data. Those data were analyzed with SAS program, and various methods such as factor analysis, cluster analysis, conjoint analysis, path analysis of Lisrel were followed. The results of this study were as follows: 1) Clothing involvement consists of the affective factor and the cognitive factor. 2) The consumers were divided into three groups with regards to the degree of their clothing involvement. 3) Significant differences were found regarding the cognitive complexity of clothing attributes among these groups.

  • Moth diversity of Mt. Duryunsan and its neighboring area, Haenam, Jeonnam, collected from 2001 to 2004 is presented. A total of 498 species were identified and a logarithmic equation to the species accumulation data provided a good fit $(R^2=0.98;$ y=218.52 LN (x)+161.88), predicting that 665 moth species are expected after ten years of collecting. Yearly species accumulation data showed that the moth faunal composition was changing by the appearance and disappearance of species: $94\~119$ species were newly collected in the following years; and $32\~90$ species were not collected in the following years. The fourth year was the most species-rich with 250 species. The need of long- term research of speciose insect taxa is briefly discussed.

  • In order to provide basis for an accurate concentration determination of volatile organic compounds(VOCs) in air, four different institutions participated in simultaneous measurements of several VOC species under the experimental scheme of the Measurement and Analysis Division(MAD) of the Korea Society for Atmospheric Environment(KOSAE). Two types of experiments were undertaken by collecting and analyzing ambient air samples from the 7th floor of Natural Science Building, Han Tang University during two day periods of the late May 1998. The first typer of experiment was conducted as five consecutive experiments at 2-hour intervals by two institutions. On the other hand. the second type of experiment was performed as two -10hr sampling by three different institutions. The data obtained from different type of experiments were examined using various statistical approaches. In general, the results of these experiments indicated that the VOC data produced by a number of Korean institutions be fairly agreeable.

  • This paper introduces a branch of qualitative method, called an in-depth interview method. By collecting data from the stories of Korean middle school students and a 9th grade American girl who used Geometer's Sketchpad and various software respectively for their mathematical problem solving, the qualitative analysis leads us to understand how such software affect their lives with mathematics subject. The unique characteristics and strands of each student's utterances reflect how software plays a role of learning aid for their mathematics learning. The arm of this study is both to get a good picture of each student's self-perceived relationship to mathematics as well as to explore external and objective parameters and factors in each student's internal situations. The qualitative descriptions of the collected data help us guide the students to the points where they could develop their interests and satisfaction with subject matter better. In this way, teachers may have more realistic understandings of how students become interested and motivated by mathematics, so that they are better able to find out ways of grasping the totalities of how the use of technology is interwoven into the school curricular.

  • There are lots of combined battlefield elements which complete the war. It looks problematic when collecting and analyzing these elements and then predicting the situation of war. Commander's experience and military power assessment have widely been used to come up with these problems, then simulated combat training program recently supplements the war-game models through recording real-time simulated combat data. Nevertheless, there are challenges to assess winning factors of combat. In this paper, we characterize the combat element (ce) by clustering simulated combat data, and then suggest multi-layered artificial neural network (ANN) model, which can comprehend non-linear, cross-connected effects among ces to assess mission completion degree (MCD). Through our ANN model, we have the chance of analyzing and predicting winning factors. Experimental results show that our ANN model can explain MCDs through networking ces which overperform multiple linear regression model. Moreover, sensitivity analysis of ces will be the basis of predicting combat situation.

  • Peripheral devices of OBCS in kyeongbu KTX serve various function. those services operate to make sure the safety of trains by displaying some malfunction signs of system and help maintain them appropriately. and they also provide various services for passengers in KTX. They divide into TECA which supports drivers with various data, PID which displays where to go, FDTR, HVAC, MDT etc. To develop superannuated devices, maintain and check its malfunction., we need to analyse hardware specification, OBCS and also protocol for communication devices simultaneously. here, we're trying to find how to find efficient approach by using a protocol analyser properly. We're going to develop peripheral devices to elevate and improve maintenance functions by collecting, compiling data.
