This study is to examine the several basic wooden movable types molded in after the Japanese Invasion of Korea in 1592. The description begins with summarizing each basic history of movable types. The parts that have not been clearly defined are relatively dealt with in detail. Subsequently the existing movable types are examined as many as possible and arranged one by one. And through analyzing the elements used in these movable type names, it is examined which elements were preferred by the existing movable type names. This preference could be helpful for naming the newly found types or renaming the existing types. Next each standard name of movable types has been selected in total 10 movable types with applying writer's own selection standard. Those are as follows: 'Moongyepak mokwhalja(文繼朴木活字)', 'Naju mokwhalja(羅州木活字)', 'Chunki kyosoekwan pilseocheja(前期校書館筆書體字)', Injosillokja(仁祖實錄字)', 'Hyojongsilokja(孝宗實錄字)', 'Huki kyosoekwan pilseocheja(後期校書館業書體字)', 'Koansanggam seomyeong daeja(觀象監 書名大字)', 'Kyeongsejeongeumja(經書正音字)', 'Panghongmujeongwon daeja(倣洪武正韻大字)', 'Seomgaemuninlok daeja(剡溪門人錄大宇)'.

The underflow type movable weirs were arranged in a multi-stage way at a section of the Chiseong River, a tributary of Geum River, where flooding is observed frequently. The flood control and the movable weir management levels were compared with the occasions of installing the existing weir for analysis. The peak discharge decreased by a maximum of 97% for the underflow type movable weir, and the downstream flood elevation decreased by a maximum of 82%. The amount of storage also increased by a maximum of 463% by the distribution and storage functions of the multi-stage arrangement of the underflow type movable weirs. It is possible to suggest that the management level of each movable weir for the target storage of the reach and the flood reduction level through the relationship among this storage, downstream peak flood elevation, and peak flow.

Dry CVT(Continuously variable transmission) consists of a driving pulley and a driven pulley joined by rubber V-belt. Each pulley consists of a fixed flange and a movable flange. The movable flange of the driving pulley has the centrifugal roller and a ramp plate in the flange. The movable flange moves toward a fixed flange under the actuation of a centrifugal roller, as the driving pulley speed increases. The main advantages of the Dry CVT with V-belt, which has been popular in Asia, are a simple mechanism, less maintenance and low cost. The important claim which have an influence on the performance of the Dry CVT is the wear of the centrifugal roller. In this study ball type is proposed instead of roller type of movable flange to resolve claim. Also experiments are carried out for new model to evaluate performances.

In this report, we describe mold materials that were used to produce movable metal type by the investment casting method during the Joseon dynasty period in Korea. Samples were obtained from the Wibuinja collection, which is held by the National Museum of Korea. Most of the mold material remnants were found in the depressed areas of the movable type specimens, and we therefore performed non-destructive analyses including XRF, EDS, and XRD. Through these analyses, we were able to identify the mold remnants as hydrocerussite [trilead dihydroxide dicarbonate, $Pb_3(CO_3)_2(OH)_2$] formed in platy hexagonal crystallites. Hydrocerussite was first used to make white pigments and cosmetics in ancient Greece, but this is the first report of hydrocerussite used as mold material applied around a disposable pattern for investment casting. The results of this study will further the understanding of the production process for early movable metal type and ancient casting technologies.

The aim of this study was to analysis the Heating/cooling performance of movable insulation system built in apartments. The process of this study is as follows: 1) Test-cells of movable insulation are designed through the investigation of previous paper and work. The type of the movable insulation used in test-cell is low emissivity(5%) insulation, measured for heating season and the thermal effects are analyzed. 2) The simulation program(Design Builder) was used in energy performance analysis. the reference model of simulation was made up to analysis energy performance on movable insulation system. 3) Selected reference model(Floors:15, Area of Unit:115.5$m^2$) for heating/cooling energy analysis, Energy performance simulation with various variants, such as slate angle of movable insulation(5$^{\circ}$, 30$^{\circ}$, 50$^{\circ}$) and position of movable insulation. Consequently, When movable insulation system is equipped with balcony window of Apartment, Annual heating energy of reference model was cut down at the average of 5.4kWh/$m^2$ or 4.6% of heating/cooling energy.

This article investigate the xylographica of Myopopyunhwakyung printed by movable type in the Chosun Dynasty in three aspects. It analyze： i ) the spread to the East Asia of Myopopyunhwakyung and its distribution； ii ) the distribution of Myopopyunhwakyung printed by movable type in the Chosun Dynasty； iii) the bibliographical characteristic of each edition. There are many editions of Myopopyunhwakyung, it is important to divide its circle of editions and to suggest the value, Myopopyunhwakyung was printed and distributed by movable type of Chojukapinja and Eulhaeja style in the Sejong and Sejo reign. Its reprinted edition was distributed from the Sungjong reign to the Youngjo reign. the bibliographic characteristic of each edition of Myopopyunhwakyung is various and peculia in the temple calligraphic style, an illustration of Buddha preaching, and the list of participants and donors.

The study is to find possibilities and problems of a small-scale modification on movable storage furniture as an answer to the residents' needs. The study selected one of the renovated housing units at "KYUDOGAKUSHA" as a case study. "KYUDOGAKUSHA" was designed by architect Takeda Goichi in 1926 and was renovated in 2006. The study investigates major two aspects of movable storage furniture, which includes the furniture's layout planning and technical issues of assembling and moving moveable storage furniture. The experimental test result shows that, 1) It is clear that island type of movable storage furniture's layout can facilitate the residents'small-scale modification even though the residents are untrained. 2) To increase the assembling efficiency, the study found that it is necessary to improve the movable storage furniture's casters so that furniture can rotate. Certain moveable furniture which played a role as a connector between other furniture pieces was not able to move vertically and caused a load on other connected furniture; this needed an improvement.

The purpose of this study was to improved the durability of a improved movable weir by replacing the improved movable weir's metal gate with a hybrid steel/glass fiber reinforced polymer composites panel gate. Because the metal gate of a improved movable weir is always in contact with water, its service life is shortened by corrosion. This study made four type of hybrid steel/glass fiber reinforced polymer composites panel gate with different steel gate surface deformation (control, sand blast, scratch and hole), flexural. Fracture properties tests were performed depending on the steel gate surface deformation. According to the test results, the flexural behavior, flexural strength and fracture properties of hybrid steel/glass fiber reinforced polymer composites panel gate was affected by the steel panel gate surface deformation. Also, the sand blast type hybrid steel/glass fiber reinforced polymer composites panel gate shows vastly superior flexural and fracture performance compared to other types.
