Background: Hysteroscopy is considered to be the gold standard not only for visualizing the cervical canal and the uterine cavity, but also for treating many different types of benign pathologies localized to those regions. The advent and evolution of endoscopic imaging and surgery during the last two decades has added new dimensions to the armamentarium of a gynecologist to combat intrauterine lesions. Office hysteroscopy is increasingly being used as a first line investigation for abnormal uterine bleeding and other diseases involving the uterine cavity. The aim of our study is to assess the diagnostic and operative efficacy of office hysteroscopy. Materials and Methods: In our department, 140 patients underwent a hysteroscopy examination and 18 of these underwent an office based hysteroscopy examination from September 1995 to March 2005. The cases who underwent an office based hysteroscopy examination were reviewed in order to assess the clinical usefulness and significance in the management of intrauterine lesions. Results: Major indication was abnormal uterine bleeding(12 cases, 66.7%). The others were a missed IUD and infertility. The hysteroscopic findings were a normal uterine cavity(6 cases, 33.3%), IUD in situ, polyp, submucosal myoma, endometrial hyperplasia and a placenta remnant. Conclusion: Office hysteroscopy is a safe, quick and effective method for making an intrauterine evaluation. In addition, it provides immediate results, offers the capacity of direct targeted biopsies of suspicious focal lesions, and offers the direct treatment of some intrauterine conditions.

'Heaundae Woosin Building' fire was the case that a fire breaking out on the $4^{th}$ floor spread out the $38^{th}$ floor which is a top story and the penthouse was destroyed by fire. After this fire, the fire safety for high rise buildings has been on the rise and several new laws and regulations related in the buildings were created. The study is to analyze Heaundae officetel building case using FDS which is one of the CFD programs for fire. The methodology of this study is to analyze the case comparing with fire spread and route from a virtual fire simulation and related articles and a video clip of actual scene fire. This study shows that a fire spreading on top of levels spent approximately 30 minutes and, which is similar to the actual fire case. Also the pattern of spread has similarity with the case. However, even if the actual fire case shows the fire pattern was "V shape", the smoke-view presents the fire dose not spread horizontally as much as the real fire case. The result shows uncertainty of the modeling based on many grids and a limitation of putting interior finish input sources and the direction of the wind might cause the difference. Also, to analyze factors influencing on a vertical fire, another fire modeling is performed by in condition of modeling environment considering concrete interior finish between buildings and no wind. The result presents the fire spread in smoke-view does not spread vertically as much as the actual case.

The expansion of the physical road in response to changes in social conditions and policy of the country has reached the limit. In order to alleviate congestion on the existing road to reconsider the effectiveness of this method should be asking. Currently, how to collect traffic information for management of the intersection is limited to point detection systems. Intelligent Transport Systems (ITS) was the traffic information collection system of point detection method such as through video and loop detector in the past. However, intelligent transportation systems of the next generation(C-ITS) has evolved rapidly in real time interval detection system of collecting various systems between the pedestrian, road, and car. Therefore, this study is designed to evaluate the development of an algorithm for queue length based real-time traffic signal control methodology. Four coordinates estimate on time-space diagram using the travel time each individual vehicle collected via the interval detector. Using the coordinate value estimated during the cycle for estimating the velocity of the shock wave the queue is created. Using the queue length is estimated, and determine the signal timing the total queue length is minimized at intersection. Therefore, in this study, it was confirmed that the calculation of the signal timing of the intersection queue is minimized.

The use of geothermal energy has increased for economically and environmentally friendly utilization, and a geothermal heat pump (GSHP) system for space heating and cooling is being used widely. As ground thermal properties such as ground thermal conductivity and ground thermal diffusivity are substantial parameters in the design of geothermal heat pump system, ground thermal conductivity should be obtained from in-situ thermal response test (TRT). This paper presents an experimental study of ground thermal properties of U and 2U type ground heat exchangers (GHEs) measured by TRTs. The U and 2U type GHEs were installed in a partially saturated dredged soil deposit, and TRTs were conducted for 48 hours. A method to derive the thermal diffusivity as well as thermal conductivity was proposed from a non-linear regression analysis. In addition, remolded soil samples from different layers were collected from the field, and soil specimens were reconstructed according to the field ground condition. Then equivalent ground thermal conductivity and ground thermal diffusivity were calculated from the lab test results and they were compared with the in-situ TRT results.

As the security requirements of mobile phones have been increasing, there have been extensive researches using one biometric feature (e.g., an iris, a fingerprint, or a face image) for authentication. Due to the limitation of uni-modal biometrics, we propose a method that combines face and iris images in order to improve accuracy in mobile environments. This paper presents four advantages and contributions over previous research. First, in order to capture both face and iris image at fast speed and simultaneously, we use a built-in conventional mega pixel camera in mobile phone, which is revised to capture the NIR (Near-InfraRed) face and iris image. Second, in order to increase the authentication accuracy of face and iris, we propose a score level fusion method based on SVM (Support Vector Machine). Third, to reduce the classification complexities of SVM and intra-variation of face and iris data, we normalize the input face and iris data, respectively. For face, a NIR illuminator and NIR passing filter on camera are used to reduce the illumination variance caused by environmental visible lighting and the consequent saturated region in face by the NIR illuminator is normalized by low processing logarithmic algorithm considering mobile phone. For iris, image transform into polar coordinate and iris code shifting are used for obtaining robust identification accuracy irrespective of image capturing condition. Fourth, to increase the processing speed on mobile phone, we use integer based face and iris authentication algorithms. Experimental results were tested with face and iris images by mega-pixel camera of mobile phone. It showed that the authentication accuracy using SVM was better than those of uni-modal (face or iris), SUM, MAX, NIN and weighted SUM rules.

There must be a balanced development of both conglomerates and small and mid-sized companies in order to secure constant economic growth and competitive edge of South Korea. Accordingly, high expectations are being placed on win-win growth and joint overseas expansion of conglomerates and small and mid-sized companies. This study seeks efficient ways to promote joint overseas expansion of major retailers and small and mid-sized companies considering the distinctiveness of home shopping by conducting interviews about joint overseas expansion of home shopping companies and small and mid-sized consumer goods companies in South Korea. To do this, interviews were conducted with three home shopping companies and three consumer goods SMEs operating in overseas markets. The results are as follows. Home shopping companies contribute to opening up overseas markets for small and mid-sized consumer goods companies, and allows them to make use of business and marketing competencies that they lack. Home shopping companies also produce visual materials or provide language translations, and help draw up documents for customs clearance in trading. They also form market development teams and provide information about the overseas markets. However, since the actual benefits from joint overseas expansion are minor for home shopping companies, there is a need for a strategy for win-win growth of both parties in the long run. To this end, it is necessary to provide substantial benefits to encourage joint overseas expansion. Ultimately, balanced development between home shopping companies and small- and medium-sized consumer goods companies should be promoted.
