Objectives : Since prostitution is multitraumatic phenomena, it is known that most women in prostitution have symptoms of posttraumatic stress disorder (PTSD) and other mental illness. In Korea, new anti-prostitution law launched in the year of 2004 imposes protecting prostituted victims at government-supported shelter. The objective of this study was to compare the mental symptoms, especially PTSD features of women who escaped from prostitution with those of control subjects. Methods : We assessed 113 ex-prostituted women who live in shelter for 8 months on the average and 65 normal control subjects. Demographic data, questionnaire for sleep, physical illness, smoking, alcohol and drug use, Stress Response Inventory, Davidson Trauma Scale (DTS), Impact of Event Scale-Revised (IES-R) were used. Results : Ex-prostituted women had significantly higher scores of DTS, IES-R, stress related responses, sleep problems, smoking problems, and alcohol problems than control group. Age and duration of sex trade of the subjects were significantly correlated with the severity or frequency of PTSD symptoms. The degree of smoking, alcohol drinking and sleep problems were also significantly correlated with the PTSD symptoms. Conclusion : These results suggested mental symptoms did not disappear even after women escaped from prostitution.

Purpose: Neurocardiogenic syncope (NCS) is the most frequent cause of fainting during adolescence. Inappropriate cardiovascular autonomic control may be responsible for this clinical event. The head-up tilt test has been considered a diagnostic standard, but it is cumbersome and has a high false-positive rate. We performed a study to evaluate whether P-wave dispersion (PWD) could be a useful electrocardiographic parameter of cardiac autonomic dysfunction in children with NCS. Methods: Fifty-four patients with NCS (28 boys and 26 girls; mean age, $12.3{\pm}1.4$ years) and 55 age- and sex-matched healthy controls were enrolled. PWD was obtained as the difference between maximum and minimum durations of the P wave on standard 12-lead electrocardiography in all patients and controls Results: The value of PWD was significantly higher in the syncope group than in the control group ($69.7{\pm}19.6$ msec vs. $45.5{\pm}17.1$ msec, respectively; P<0.001). The minimum duration of P wave was shorter in the syncope group than in the control group ($43.8{\pm}16.8$ msec vs. $53.5{\pm}10.7$ msec, respectively; P<0.001). Left atrial volume was not different between the groups on transthoracic echocardiography. Conclusion: PWD on echocardiography could be used as a clinical parameter in patients with NCS.

비상위치송수신장치(ELT)는 항공기 추락 시 조난 신호를 송출하는 장비이다. 유용한 장비이지만 항공기 추락과 경착륙에 대한 오판으로 인하여 잘못된 조난신호를 송출하기도 한다. 이러한 문제점은 현재 사용되고 있는 기계식 G-스위치의 부정확성에 그 원인이 있다. ELT의 성능 개선을 위하여 기계식 G-스위치를 MEMS 가속도계로 대체한 ELT 시스템을 개발하였다. ELT 시스템은 가속도 정보 수집/분석 시스템과 추락 판단 프로그램, 추락 상황에서 위치 정보를 제공하기 위한 GPS 수신 시스템으로 구성되어 있다. 또한, ELT 시스템을 검증하기 위한 자유 낙하 실험대를 제작하였다. 자유 낙하 실험대는 추락과 경착륙에 해당하는 충격 가속도와 충격 유지 시간을 모사할 수 있도록 설계하였다. 자유 낙하 실험대를 이용하여 개발한 ELT 시스템이 정확히 작동함을 확인하였다.

"Wind and Ports" is a European project that has been carried out since 2009 to handle wind forecast in port areas through an integrated system made up of an extensive in-situ wind monitoring network, the numerical simulation of wind fields, the statistical analysis of wind climate, and algorithms for medium-term (1-3 days) and short term (0.5-2 hours) wind forecasting. The in-situ wind monitoring network, currently made up of 22 ultrasonic anemometers, provides a unique opportunity for detecting high resolution thunderstorm records and studying their dominant characteristics relevant to wind engineering with special concern for wind actions on structures. In such a framework, the wind velocity of thunderstorms is firstly decomposed into the sum of a slowly-varying mean part plus a residual fluctuation dealt with as a non-stationary random process. The fluctuation, in turn, is expressed as the product of its slowly-varying standard deviation by a reduced turbulence component dealt with as a rapidly-varying stationary Gaussian random process with zero mean and unit standard deviation. The extraction of the mean part of the wind velocity is carried out through a moving average filter, and the effect of the moving average period on the statistical properties of the decomposed signals is evaluated. Among other aspects, special attention is given to the thunderstorm duration, the turbulence intensity, the power spectral density and the integral length scale. Some noteworthy wind velocity ratios that play a crucial role in the thunderstorm loading and response of structures are also analyzed.

Futurists objected the existent style, that is the conventional fashion, and took part in these disciplines of fashion to make clothes the instruments being able to represent the individuality. Giacomo Balla and fortunato Depero, pain-ters who in 1915 were to work with Diaghilev's company, were the first to see clothing as a dynamic interfaced between th body and the atmosphere, between physical gestures and the urban context, which could be translated into encounters between forms and colours, volumes and architecture. For them, clothing began to exist as an object and an event, something to be removed from a mainly static conception and made mobile, active. The interaction between movement and clothing was based on the relativity of perception : the appearance and disappearance of the body produced points without dimension or duration which served, as Balla wrote in the Futurist Mnaifesto of Men's Clothing to“renew incessantly the enjoyment and impetuous movement of the body”. The historical achievement in the effort for the reformation of Futurist, Art to Wear. First, for Futurist, clothing is removed from a static conception and focused on dynamics. Second, Balla used asymmetry in men's clothing. Moreover he supposed dynamic men's clothes by using optical intersection. Third, the after image of Chronophotograph represented rapidity. This rhythmic expression is the fore-runner in Optical and Kinetic Art of Visual Art. Fourth, Futurist emphasized flexibility in fashion. They aimed to create‘Clothing Machines’whose parts would interact to aceelerate the real and virtual, inner and outer movement of the human being. Fifth, the variety and short life of cutting skills and colors are focused and‘Fast Substance’in fashion is admitted by Futurists. Futurist concern with clothing was not lim-ited its appearance in terms of cut and colour. What important was also the way it appeared and disappeared according to fashion. It was a“fast substance”, able to reflect rapid, sudden changes of social and aesthetic taste. To reach to the aim of internationalization, Gesamtkunstwerk in our Art to Wear, it is extremely meaningful to examine art fashion which is created under the conception of Gesamtkunstwerk production of avang garde artist in the early 20th century and look at formative conscious of truth, goodess and beauty synthetically which they faced on their works of art.

Base-isolation is now being adopted as a retrofitting strategy to improve seismic behaviour of reinforced concrete (r.c.) framed structures subjected to far-fault earthquakes. However, the increase in deformability of a base-isolated framed building may lead to amplification in the structural response under the long-duration horizontal pulses of high-magnitude near-fault earthquakes, which can become critical once the strength level of a fire-weakened r.c. superstructure is reduced. The aim of the present work is to investigate the nonlinear seismic response of fire-damaged r.c. framed structures retrofitted by base-isolation. For this purpose, a five-storey r.c. framed building primarily designed (as fixed-base) in compliance with a former Italian seismic code for a medium-risk zone, is to be retrofitted by the insertion of elastomeric bearings to meet the requirements of the current Italian code in a high-risk seismic zone. The nonlinear seismic response of the original (fixed-base) and retrofitted (base-isolated) test structures in a no fire situation are compared with those in the event of fire in the superstructure, where parametric temperature-time curves are defined at the first level, the first two and the upper levels. A lumped plasticity model describes the inelastic behaviour of the fire-damaged r.c. frame members, while a nonlinear force-displacement law is adopted for the elastomeric bearings. The average root-mean-square deviation of the observed spectrum from the target design spectrum together with a suitable intensity measure are chosen to select and scale near- and far-fault earthquakes on the basis of the design hypotheses adopted.

Background: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric age group. All patients with RMS regardless of their initial stage or group receive combination chemotherapy as 'standard therapy' consisting of vincristine, actinomycin-D and cyclophosphamide. Actinomycin-D was not readily available in Turkey at one time. Carboplatin was used instead in order to prevent delays in treatment. The aim of this report is to present the results of patients with rhabdomyosarcoma receiving carboplatin or actinomycin-D therapy. Materials and Methods: Twenty four patients with rhabdomyosarcoma treated between December 2000 and June 2011 were included in this retrospective study. The patients were treated according to International Rhabdomyosarcoma Study Group guidelines. Eleven patients were treated with actinomycin-D and 13 with carboplatin ($250mg/m^2/dose$ for 2 days). The two groups were then compared in terms of 2- and 5-year overall survival (OS) and hematological and non-hematological toxicities. Results: Age, sex, stage and the mean duration of follow-up were similar in both groups (p>0.05). Two- and five-year OS levels were 68.2% in the carboplatin group and 78.0% and 40.0%, respectively, in the actinomycin-D group. There was no statistical difference in the number of febrile episodes (p=0.86) and no other hematological and non-hematological adverse effects were recorded in both groups. Conclusions: The findings show that carboplatin can be used as an alternative drug in the primary treatment of rhabdomyosarcoma in the event that actinomycin-D is unavailable or not tolerated.
