This paper aims at researching on the substantial characters of the memorial address, namely the mookseo-myeongs(墨書銘), written at the members of the wooden buildings in the late period of Goryeo Dynasty and the early period of JoseonDynasty. In this paper, I pursued to declare the systematic origins by the comparison the Buddhist buildings with the other buildings, on the focused the written patterns. Furthermore, I tried to examine the transitional trends in the late period of Joseon Dynasty. The results are as follow: First, it is supposed that the mookseo-myeongs of the Buddhist buildings were not used for the a memorial address for the ceremony of putting up the ridge beam, so to speak the sangryang-muns(上樑文), but the prayer address(發願文) to memorize the donations of the believers for the constructions. Second, it is supposed that 'the short sangryang-muns' were originated in the mookseo-myeongs of Buddhist buildings and the other ancient prayer address. In the late period of JoseonDynasty, those were established in the formal literary styles. Third, to the early period of JoseonDynasty, 'the long sangryang-muns' were partially used in the several royal palaces. In the late, those were widely used not only in the royal palaces but also in Buddhist buildings, but those literary patterns were rarely changed from the former types.

Recently, people in urban areas ask for the creation of space for amenity and improvement of environmental problems, in such a condition the activation and reformation of city have become an important subject. The basic element of a city structure is the street. Therefore in this study, a transition of street spaces of a city was investigated. This study will be a basis for the planning of urban space in order to realize a comfortable and fascination urban life. In this paper, the study areas chosen were "Ginza", "Kyobashicho", "Nihonbashicho", "Honcho", "Tsukizi", "Hatchoboricho", "Ningyocho", "Ningyocho" which are the central places and business areas of capital Tokyo of Japan. The main streets were chosen for investigative subjects because they were planned as making a division of block in a city planning. Using maps and references the data was illustrated and the investigation was focused on the period from the Edo era to present time. (1) A periodical division for the basis of a street transition. (2) Consideration of methods in a plan and design for street spaces in each period. (3) A special feature and process of a street transition in each period. (4) A structure of a street and a construction form. (5) A classified structure of streets. (6) A process of a transition for each street.

Long Sleeve Costume is often seen not only in ancient China but also in various neighboring places throughout the time. Costumes show the societies cultural preferences and values at that time, and Long Sleeve Costume is no exception. In my research, 1 focused on the time period from Han Dynasty to Tang dynasty in ancient China. During Han dynasty, Shenyl style robe(심의형 포) was widely worn, and it shows very little foreign cultural influence. For the period of Wei·Jin Southern and Northern Dynasties, foreign aspects of costume started to show up Possibly due to the influence of Buddhism and influx of foreign tribes. For instance, it is not too difficult to find hufu (호복) as well as Shenyl style robe, and it appears this Wei Jin Southern and Northern Dynasties may have been a transitional period of accommodating two cultures without complete merger. Now, when it comes to Tang dynasty, we observe a creation of new cultural form in costume after adopting exotic culture. Because Sh ny style robe. often observed for a long time in Chinese history, disappeared, and tuanling(단영) and fanling(번영) became the main stream in their costume style in Tang dynasty.

Objectives : Much is still unknown about the neurophysiological mechanisms or dynamics of the sleep onset process. Detrended fluctuation analysis (DFA) is a new tool for the analysis of electroencephalography (EEG) that may give us additional information about electrophysiological changes. The purpose of this study is to analyze long-range correlations of electroencephalographic signals by DFA and their changes in the sleep onset process. Methods : Thirty channel EEG was recorded in 61 healthy subjects (male:female=34:27, age=$27.2{\pm}3.0$ years). The scaling exponents, alpha, were calculated by DFA and compared between four kinds of 30s sleep-wakefulness states such as wakefulness, transition period, early sleep, and late sleep (stage 1). These four states were selected by the distribution of alpha and theta waves in O1 and O2 electrodes. Results : The scaling exponents, alpha, were significantly different in the four states during sleep onset periods, and also varied with the thirty leads. The interaction between the sleep states and the leads was significant. The means (${\pm}$ standard deviation) of alphas for the states were 0.94 (${\pm}0.12$), 0.98 (${\pm}0.12$), 1.10 (${\pm}0.10$), 1.07 (${\pm}0.07$) in the wakefulness, transitional period, early sleep and late sleep state respectively. The mean alpha of anterior fifteen leads was greater than that of posterior fifteen leads, and the two regions showed the different pattern of changes of the alpha during the sleep onset periods. Conclusions : The characteristic findings in the sleep onset period were the increasing pattern of scaling exponent of DFA, and the pattern was slightly but significantly different between fronto-temporal and parieto-occipital regions. It suggests that the long-range correlations of EEG have a tendency of increasing from wakefulness to early sleep, but anterior and posterior brain regions have different dynamical process. DFA, one of the nonlinear analytical methods for time series, may be a useful tool for the investigation of the sleep onset period.

The purpose of this study was to investigate the change of clothes in modem Korean women in terms of a socioeconomical background, the introduction to western clothes, and the improvement of clothes between the opening period of ports in the early 1900's and 1960's. In addition, the study investigated how western clothes became popular in a Korean society along with the traditional' Korean clothes, Hanbok. The radical social change since the opening of ports motivated the change in the way of Korean women's thinking, and consequenty the improvement of Hanbok which developed into the clothes-improvement-movement. It was not until 1905 that the improvement of clothes was hotly debated particularly in the matter of abolishing Jangeui and the extreme length of Jeogori and Chima. The Tongchima-Jeogori style which lengthened Jeogori and shortened Chima was widely accepted as everyday wear until the western clothes substituted them after the Independence from Japanese Conquest. As the length of Chima shortened, there occurred a change in Boson and Jipsin as well. There appeared shoes and Gomoosin in place of Jipsin, socks in stead of Boson and were popularized until after the Liberation in 1945. The popularity of Gomoosin diminished markedly with the diversification of shoes styles, due to the improvement of the standard of living with economic development in the 1960's. The traditional Hanbok was gradually differentiated according to the social status, for instance student, teachers, ordinary women, girls and Kisaeng. Especially since the white clothes caused much trouble in washing and sewing, there came into being the movement of wearing colorful clothes. The Movement of abolishing white clothes and promoting of wearing colorful clothes was enforced during the period of Japaness conquest from the 1920's to the Liberation, which consequently stimulated an interest for colors of clothes. The period under the war between 1937 and 1945 was especially noted for the extreme regulation over the clothes. The Japanese government forced each group of women, e.g., girl students, a young women's association, school teachers, and ordinary women and girls, to wear their own uniforms. Also, It recommended the use of Tongchima in stead of long skirts, and buttons in place of Coreum so as to conserve textile encouraging the use of other substitutes to save resources. The western clothes, a model of clothe's improvement was deemed as a symbol of modernization and enjoyed general popularity. The supply of relief clothes after the Korean war accelerated the expansion of western clothes even further and the trend of westernization along with economic progress in the 1960's resulted in wearing of western clothes as everyday dress. The expansion of western clothes as casual wear rapidly diminished wearing of Hanbok which in turn took the position of ceremonial dress worn in special cases only. Hence the Korean women's clothes were dualized into traditional Hanbok and western clothes and the western clothes that stems on its convenience was settled as everyday wear where as the Hanbok appeared as ceremonial dress stressing on ornamental features. As mentioned aboved, we are able to discovered an orientation in the course of transitional process of modern Korean women's clothes admist diversified changes, which is a consistent pursuit of convenience and practicality based upon progmatism. The trend such as this carne into a finale' as women's dress became dualistic in forms of Hanbok and western clothes, and the change since then is supposed to proceed in two forms of dress featuring its own style.

Transforaminal lumbar interbody fusion (TLIF) is commonly used procedure for spinal fusion. However, there are no reports describing anterior cage dislodgement after surgery. This report is a rare case of anterior dislodgement of fusion cage after TLIF for the treatment of isthmic spondylolisthesis with lumbosacral transitional vertebra (LSTV). A 51-year-old man underwent TLIF at L4-5 with posterior instrumentation for the treatment of grade 1 isthmic spondylolisthesis with LSTV. At 7 weeks postoperatively, imaging studies demonstrated that banana-shaped cage migrated anteriorly and anterolisthesis recurred at the index level with pseudoarthrosis. The cage was removed and exchanged by new cage through anterior approach, and screws were replaced with larger size ones and cement augmentation was added. At postoperative 2 days of revision surgery, computed tomography (CT) showed fracture on lateral pedicle and body wall of L5 vertebra. He underwent surgery again for paraspinal decompression at L4-5 and extension of instrumentation to S1 vertebra. His back and leg pains improved significantly after final revision surgery and symptom relief was maintained during follow-up period. At 6 months follow-up, CT images showed solid fusion at L4-5 level. Careful cage selection for TLIF must be done for treatment of spondylolisthesis accompanied with deformed LSTV, especially when reduction will be attempted. Banana-shaped cage should be positioned anteriorly, but anterior dislodgement of cage and reduction failure may occur in case of a highly unstable spine. Revision surgery for the treatment of an anteriorly dislodged cage may be effectively performed using an anterior approach.

This study aims to investigate the formation and sedimentary environment including formative period, grain composition and climate change from loess-paleosol sequence deposited on a gravel bed of river terrace in the Jincheon Basin, Chungbuk Province. The Jincheon section consists downward of a surface layer, loess-paleosol sequence, transitional layer I, transitional layer II and gravel bed. It can be suggested from the OSL age dating that the sequence was deposited during MIS 6 to 4. The sequence can be divided into four horizons based on the variation in the magnetic susceptibility values. Grain size analysis reveals that the sequence indicates similar properties of grain size to loess deposits in Korea and especially, the Y values in the sequence are lower than those in the loess and paleosol horizons in the Chinese Loess Plateau and similar to those in the Red Clay in the Chinese Loess Plateau and Xiashu loess in the lower reaches of the Yangtze River. These Y values in the sequence can be attributed to the remote source and/or experience of intensive weathering process after deposition in the Korean Peninsula.

Raoul Dufy devoted and was involved in textile design between 1910 and 1928. It was a transitional period in fashion. especially Poiret took an important role as a fashion designer at that time. After meeting Poiret, he won the fame as a textile designer rather than a painter, in his early stages, He had been deeply involved in fashion design. For instance Dufy and Poiret shared their world of art, collaborated to mount exhibitions, the Print textile fabrics by Dufy was used for dresses by Poiret and so on. The textile design which showed Dufy's artistic abilities was used as a method of expression of an exchange and a communication between art and fashion in the same period, through collaborations with Poiret. For instance, Dufy as a fauvist created and produced textile designs using his magnificent and cheerful colors and lines. He brought about a revolution in the textile design due to his participation in fashion design, as well as encouraging fashion designers. Textile design by Dufy, which grafted onto his world of art impressed Poiret greatly. It proposed the new direction of the fashion and influenced modern costume. The positive collaborate between Dufy and Poiret provided a momentum to a costume for being a part of art. Textile design as one of the important area in modern fashion needs a design originality for creating a high value-added products.

In the present study, velocity profile and wall shear stress distributions of developing turbulent oscillatory flows in an oscillator connected to straight duct located in exit region of a curved duct was investigated experimentally. The experimental study for air flows was conducted to measure axial velocity profiles, shear stress distributions by using the Laser Doppler Velocimetry(LDV) system with the data acquisition and processing system of Rotating Machinery Resolver(R.M.R) and PHASE software. The results obtained from experimental studies are summarized as follows. The critical Reynolds number for a change from transitional oscillatory flow to turbulent flow was about 7500, in the 60region of dimensionless axial position which was considered as a fully developed flow region. The turbulent oscillatory flow, velocity profiles of the inflow period in the entrance region were gradually developed, but those of the outflow period were not changed nearly. Velocity profiles of inflow and outflow were shown as a symmetric form in a fully developed flow region. The wall shear stress distributions of turbulent oscillatory flow increase rapidly as the flow proceeds to downstream and flow was in good agreement with the theoretically.

Background: Bertolotti's syndrome (BS), a form of lumbago in lumbosacral transitional vertebrae, is an important cause of low back pain in young patients. The purpose of this study was to assess the etiology of low back pain and the efficacy of treatment offered to patients with BS. Methods: All patients of BS Castellvi type1a during a period of 6 months were enrolled in the study. The patients underwent interventional pain procedures for diagnosis and pain relief. Response to the therapy was assessed based on VAS and ODI scores. A 50% decrease in VAS score or a VAS score less than 3 would be considered adequate pain relief. Results: All 20 patients diagnosed with BS during the 6-month observation period had scoliosis. Common causes of back pain were the ipsilateral L5-S1 facet joint, neoarticulation, the SI joint, and disc degeneration. Responses to various interventions for pain relief were different and inconsistent from patient to patient. In particular, responses to interventions for neoarticular pain were generally poor. Conclusions: Pain in patients with BS does not usually respond to interventional pain treatment. A very dynamic treatment approach must be pursued while managing BS patients, and the treatment plan must be individualized at various stages in order to obtain satisfactory pain relief.
