A caching is a useful technique to alleviate performance degradation due to the inherent narrow bandwidth by reducing contention of broadcast requests. In this paper, we propose a caching strategy for pull-based data broadcast system which considers data popularity among clients. In addition, the proposed strategy also reflects recentness of data access based on data broadcast version. Then, we evaluate the performance of proposed strategy through a simulation approach. According to the results, the strategy considering both hit ratio and miss cost shows better performance than the traditional LRU. In addition, the strategy considering data popularity among clients shows better performance in some cases.

The purpose of this study was to identify the ecological characteristics of Namhan Mountain Fortress Walls vascular plants through investigation and analysis of Namhan Mountain Fortress Walls and to provide basic data when establishing a plan for conservation and management of Namhansanseong Fortress Wall vascular plants. The result of this survey revealed 249 taxa composed of 77 families, 169 genera, 222 species, 5 subspecies, 19 varieties and 3 forms. In terms of life form of Namhan Mountain Fortress Walls, the appearance rate of Hemicryptophytes(H) was high. Rare plants was 1 taxa and Korea endemic plants was 5 taxa. The total number of floristic regional indicator plants was 15 taxa, gradeI 9 taxa, gradeII 2 taxa, gradeIII 3 taxa, gradeIV 1 taxa. Among them, Polygala tatarinowii Regel is considered to the most important(gradeIV), and it is first description because in Gyeonggi-do, as no additional forms have been confirmed other than this site. Plants identified as rock vegetation were found in 21 taxa. Invasive alien plants were identified 20 taxa. Plants distributed on the walls of Namhan Mountain Fortress, such as Aconitum longecassidatum Nakai, Clematis heracleifolia DC. var. tubulosa (Turcz.) Kuntze, Hylotelephium spectabile (Boreau) H.Ohba and Polygala tatarinowii Regel etc, are feared to decrease the number of species and individuals due to the loss of walls, the spread of invasive alien plant and human interference, so conservation and management measures are needed.

The present study proposes and examines a new type of multiple-choice math test. In this format, the options are the intermediate derivatives of the math problem solution process rather than the final answers. This idea originates from the studies on the effect of worked-out examples. In these studies, it has been shown that students learn better when they were presented with worked-out examples than when presented with final answers by themselves. In line with these findings, we introduced the intermediate derivatives of the solution process as the options of multiple-choice items so that the test-taker will have a chance to examine the solution process. The test was implemented as a computerized test in which students can solve problems in a short answer format, and then pick a multiple-choice option which appears when requested. The experimental group had multiple-choice options which were intermediate derivatives of the solution process, and the control group had the final answers as the options as in most multiple-choice tests. The participants were 6th graders in elementary school. The posttest results revealed that the average score of the experimental group was higher than that of the control group. The results suggest that tests that use intermediate derivatives of the problem solution process as options can be used as learning tools in the classrooms. Finally, directions for further studies were discussed.

It was proposed that proper problem solving practice should improve students' questioning in physics. In the previous researches, improvement in students' questioning was observed after practice of making questions given the examples of desirable questions. In this study, the problem solving strategies used by experts were introduced to students in the form of step-by-step guide to follow in problem solving practice. The directions in the guide were concrete and operational for students to understand the expected behaviors explicitly. It was assumed that students could pinpoint the difficulty specifically through this guide, which would result in positive effects on students' recognition and expression of their own questions. The subjects in this study were college freshmen enrolled in the introductory physics for science or engineering major. The physics problems from the textbook were solved and practiced in the traditional way for controlled group. Worksheets designed to follow experts' problem solving strategies were used for the experimental group. Two groups were taught in the same way during lecture part of the class. Students were asked to describe the difficulties they had during homeworks or tests. Questions in this study means these descriptions written by students although they were not necessarily in the form of interrogative sentences. The questions were analyzed both in quantity and quality. Quantitatively, more students spontaneously turned in their questions in the experimental group than in the controlled group. Regarding the quality, there were more students in the experimental group than in the controlled group who described their difficulties in detail or recognized the need for the procedural knowledge.

This study was undertaken to investigate the quality properties of yakchobugak as affected by lactic acid bacteria and waxy rice paste for improving palatability of yakchobugak of Agastache rugosa. Total sugar contents of lactic acid bacteria-fermenting waxy rice paste gelatinized at $90^{\circ}C$ were higher than that of $70^{\circ}C$. Reducing sugar contents were $2{\sim}5$ times higher in $70^{\circ}C$ waxy rice paste than in $90^{\circ}C$ waxy rice paste and increased as the fermentation progressed. Total acidity of waxy rice pastes gelatinized at $70^{\circ}C$ and fermented for 15 hours were $2.7{\sim}1.3$ times higher than at $90^{\circ}C$, and then Lactococcus lactis had the lowest total acidity during fermentation. Viscosity of fermented paste (VFP) were lower than those of raw paste. VFPs gelatinized at $90^{\circ}C$ were markedly higher than those at $70^{\circ}C$ over 28% concentration. In L. lactis and Lactobacillus plantarum, VFPs fermented for 15 hours were over $2{\sim}3$ times lower than those fermented for 40 hours. Hunter's color lightness (L) and yellowness (b) were decreased according to the elevation of gelatinization temperature and fermentation time. L. lactis and L. plantarum-producing waxy rice pastes were the uniform micell type with a large air-pore size and amorphous micell type with a small air-pore size, respectively. Based on these results, L. lactis was a lower lactic acid-producing bacteria as well as uniform air-pore distribution on waxy rice paste. It was found to be a good sourpaste-fermenting strain for enhancement of quality properties of yakchobugak, as revealed through viscosity, total acidity, Hunter's color b value and scanning electron micrographs.

The first priority we face in the conservation of wall paintings, is the conservation of painting layer. The 'painting layer' is sometimes called the pigment layer, and refers to the painted surface. For the consolidation of this painting layer we use 'fixative'. Fixative is a common adhesive which has been used in various field and conservators have made up for the weak points in the consolidation of wall paintings. In my thesis, I will summarise the range of use, standards of selection, and results of research on the use of fixative in the conservation of European paintings. In addition, I will describe various kinds of our traditional fixatives. As synthetic resins have proved that it is not ideal as a fixative for wall painting, conservators have studied to find an alternative. Same as European conservators, Asian scientists has researched to find alternative fixative which is more suitable to the wall paintings in Asia based on their traditional techniques and materials. Therefore, 1 have studied to find an adequate fixative for our own wall paintings and I could conclude that we can consider traditional fixative which is made of 'seaweeds' as an alternative and it is very important to proceed research and experiment on this material.

The limited animation method which is a Japanese Animation frame production method was born in the U.S. but it is Japan where it was most actively used and developed. With this in mind, this researcher conducted a comparative study on the movements shown in animated films of the U.S. and Japan to identify success factors. For an analysis of the animated films of the two countries, first, the difference between orthodox animation and experimental animation was analyzed. Second, the concept of limited animation was reviewed, as well as its difference from full animation. Lastly, for an analysis of the difference between animations of the U.S. and Japan, 'Disney's 12 principles of animation' was applied.
