Science and technology are deeply based on the invention of photography. The images that were made through machines and scientific process were not just delicate images. Photography was used wherever accurate record and realistic description were needed, such as public culture, art, advertisement, science research and so on, so it became an important part of anthropologic culture. However, the history of photography in the present photography education mainly deal with photographic tendency of famous photographers, the change of art paradigm by time period, social changes through big wars, thus there is a lack of diverse perspective in the history of photography, such as technological perspective. In this study, the history of photography was examined through science and technology, and analyzed how photography was affected and changed by the stage of important technological accomplishment. From this point of view, It will be helpful to understand modern photography, and meaningful to be a good reference. Furthermore, by understanding that photography relies on technology, the people who majored in photography will realize how important studying photographic technology and theories is.

This study was started under the judgement that reviewing $\ulcorner$A Survey Report of Korean Architecture$\lrcorner$, which contains photographs and drawings by Sekino Tadashi and which was also made under the order of the Japanese government(1902), would make it possible to consider in detail the status of Korean buildings in the period of the Korean Empire. The focus of the study. was put on three main parts of the temple, especially the central parts. The photographs and drawings as mentioned above showed that changes in the layout of buildings in the central part of the temple were made between the period of the Korean Empire and that of Japanese occupation. Thus the purpose of the study is to investigate when changes in building layout in the central part of the temple were made and what made such changes to be caused, obtaining information necessary for future changes in the precincts of the temple. Results of the study can be summarized as follows. First, 'Seonchal Daebonsan Beomeosa feonkeongdo' and 'Gyeongsangnamdo Dongraegun Beomeosa Geonmul Jeondo' were made in a same period. While, 'Chosun Gojeok Dobo', published by the government-general of Chosun, was a collection of photographs taken by Sekino Tadashi for about 30 years from 1902 to 1933 under the order of the Japanese government. But there were few changes in the building layout of the temple shown in the three materials. Second, one of the photographs and drawings made since 1933, not contained in 'Chosun Gojeok Dobo', and discovered by this researcher was 'Seonchal Daebonsan Beomeosa Annae' which was published by the temple itself after national independence from the period of Japanese occupation, indicating the main reason of changes in building layout as mentioned above. In conclusion, the layout of buildings of the temple began to be changed on a large scale, with so-called 'Cheyongseol' ignored, when Buddhist monk Cha Woon Ho established a 7-storied sarira tower to the left of the main building in the center of the upper part in 1936. In addition, the axis line connecting between Hwaeomjong and Seonjong was also changed at that time.

This paper proposes history-aware random early detection (HRED), a modified version of RED, to lessen bandwidth monopoly by a few of stations employing multiple parallel TCP flows. Stations running peer-to-peer file sharing applications such as BitTorrent use multiple TCP flows. If those stations share a link with other stations with only a small number of TCP flows, the stations occupy most of link bandwidth leading to undesirable bandwidth monopoly. HRED like RED determines whether to drop incoming packets according to probability which changes based on queue length. However it adjusts the drop probability based on bandwidth occupying ratio of stations, thus able to impose harder drop penalty on monopoly stations. The results of simulations assuming various scenarios show that HRED is at least 60% more effective than RED in supporting the bandwidth fairness among stations and at least 4% in utilization.

Purpose : To compare lumbar disc changes between initial lumbar spine (L-spine) MRI and follow-up (f/u) MRI that were performed due to recurred backaches. Materials and Methods : A total 50 patients who had undergone f/u L-spine MRI were retrospectively reviewed. Five discs (L1-S1) were surveyed in each f/u MRI. Lumbar disc changes were defined as no change, aggravations, or improvements compared to initial disc states. These states were defined on the basis of morphologic status and disc levels. Results : In a total of 250 discs in 50 patients, 31 discs (12.4%) showed morphologic changes of disc lesions, whereas 219 discs (87.6 %) showed no changes. Among the 31 disc lesions, 24 were aggravated and 7 were partially improved. And on the basis of disc status, initially abnormal discs revealed any morphologic changes of the degree of disc herniation. A total of 33.3% of the morphologic changes are noted in initially extruded discs. Fifteen morphologic changes of disc lesions were located at the L4-5 level. Conclusion : Our results suggest that correlations between lumbar disc herniations and back pain symptoms are limited, and that evaluations of extra disc lesions are required.

The purpose of this study is to analyze the Korean War photographs in Korean history textbooks. This paper deals with the ways of describing Korean War in history textbooks. The Korean War photographs adopted in this study, using qualitative and quantitative analysis. The photographs analyzed for this study were in the 6 different textbooks in high school level. This paper focuses on how photographs of the textbooks help students create various memories about Korea War. The photographs of the textbooks, before the 7th Educational Process, decribe Korean War as victorious war. Meanwhile, the Korean War photographs in Korean modern and contemporary history textbook emphasize traumas of the war.

This thesis is mainly about the changes of Garment's collar(옷깃) and outer collar (옷섶) which indicate the identification of dress history. Through the observations of some reports about important folk materials and genuine objects, the author has investigated and rearranged them focusing on Yi-Dynasty. (1400-1900) For the shape of the outer lapels(겉깃) of Korean Jacket(저고리) were used together Squar-Tray-Collar(목판깃), Sharped-Collar(칼깃), and Dang ko-Collar(당코깃) and coming to the end of inner lapels(안깃) formed squar-tray-collar. Squar-tray-collar and sharped-collar were mainly used together for the shape of the outer lapels of Korean overcoat(포). Dang ko-collar was seen only in two overcoat. Coming to the 18th centry, the outer lapels became round-edged like those of jackets, while the inner lapels formed squar-tray-collar. In the process of positional changes of the collar and outer collar of Korean jacket and overcoat, the outer lapels positioned outside the outer collar, or a part of width of collar's positioned upon the outer collar, or the whole outer lapels positioned inside the outer collar. And through these changes the current position of the outer lapels became settled in the end of the 19th centry. But the inner lapels did not undergo many changes compared with the outer ones, and their position was mainly outside the outer collar like those of current lapels. And the garment's collar and outer collar of jacket and overcoat became small while the width and length of breast-tie(고름) became large.

Purpose: The purpose of this study was to investigate the effects of leg length discrepancy on kinematic changes of the pelvis and hip during gait. Methods: A total of ten healthy women with no history of neurological, musculoskeletal surgery or injuries, or pain in the lower limbs were recruited. They were assigned to two groups; the experimental group (LLD) consisting of five subjects leg length discrepancy of 10mm to 18mm and the control group (CON) consisting of five subjects leg length discrepancy of<10 mm. All participants were instructed to perform three walking trials for further analysis by using the Cortex 3.0 software program. Independent T-test and Mann-Whitney test were used to examine the effects of mild LLD on kinematic changes of the pelvis and hip during gait. Results: Angles of hip flexion, hip abduction, pelvic obliquity, and pelvic tilt in the experimental group were not significantly different compared to those of the control group. Conclusion: Mild leg length discrepancy induces kinematic changes in the lower limbs, including decreased hip flexion, increased hip abduction, and increased pelvic obliquity in the shorter limb, and increased hip adduction and increased pelvic obliquity in the longer limb. However, those changes were not significant.

The museum architecture has been developed with new social and cultural movement because of the its representative role of cultural character. After emergence of the modern museum in Korea, the function and role of the museum has been changed and developed especially after increasing role by local government. The cultural desire by the new pace of consumerism has requested museums to undergo with some changes and advancements in their function and programs. This research aims to examine the progress of museum programs in Korea even though it has sort history. The scope of the analysis is discussed the extension of existing and new national museums which could be the measurement of the direction of the policy for museum. These changes have a tendency to correspond to social and cultural demands. Based on the existing program, new programs accommodate education and services which represent the characteristic of the museums. These changes caused the extension of the existing museums and the emergence of the small museums which has special program fields and even influences to expand existing museums for sub-characters. The study for chronological changes could be useful to establish the basic guidelines of the configuration for the museum program and space in the early stages for the new construction.

The objective of this study is to examine the costumes of the period covered in the writings of Shilhak (practical science) scholars and to research the history of costumes and their characteristics by examining how they are worn in genre paintings which are said to describe the actual life of the period. This should be studied in order to correctly establish the history of costumes. To begin with, through the writings of the representative Shilhak scholars who are thought to have affected the changes in ordinary costumes for woman, this study examined how ordinary woman of the period looked in their costumes and how they regarded various costumes they had. Then, how their viewpoints of costumes influenced ordinary costumes was investigated. Not only relics, but what was commonly worn, as they appeared in the genre paintings that contain information about daily living of that period, were researched chronologically. The results of this study showed that the change in ordinary costumes for woman in the late Chosun period was affected by Shilhak scholars who had ideologies of Shilsakusi (use of positive methods in studying), Yiyonghusaeng (the promotion of commerce and industry and the development of techonologies), and Ky ngsech'iyong (pursuit of stability in a rural economy). Moreover, after those changes there were many more changes. However, the criticism of costumes of that time and the will of revolution affected some time, costumes changed directly. The forms of the costumes had been changed in a variety of ways following the tendencies of the times, but the origin of today's hanbok (Korean traditional dress) had already been fixed in the late Choson period. Yet, today's hanbok are for special occasions, not worn as ordinary clothing. Thus, there are several reasons why the hanbok is not suitable for daily life. One of the reasons is that Korean could not cope with the western costumes indepen-dently imported during Japanese occupation in the last period of the Choson Dynasty and con-tinuing the Japanese Colony. Thus, only a part of the ordinary costume of the late Choson period has remained until now.
