  • Traffic congestion is a severe problem in many modern cities around the world. Real-time and accurate traffic congestion identification can provide the advanced traffic management systems with a reliable basis to take measurements. The most used data sources for traffic congestion are loop detector, GPS data, and video surveillance. Video based traffic monitoring systems have gained much attention due to their enormous advantages, such as low cost, flexibility to redesign the system and providing a rich information source for human understanding. In general, most existing video based systems for monitoring road traffic rely on stationary cameras and multiple vehicle tracking method. However, most commonly used multiple vehicle tracking methods are lack of effective track initiation schemes. Based on the motion of the vehicle usually obeys constant velocity model, a novel vehicle recognition method is proposed. The state of recognized vehicle is sent to the GM-PHD filter as birth target. In this way, we relieve the insensitive of GM-PHD filter for new entering vehicle. Combining with the advanced vehicle detection and data association techniques, this multiple vehicle tracking method is used to identify traffic congestion. It can be implemented in real-time with high accuracy and robustness. The advantages of our proposed method are validated on four real traffic data.

  • The increasing size and complexity of modern construction projects demands mature capabilities of onsite personnel with regard to recognizing unsafe situations. Construction safety training is paper or computer-based and suffers from a distinct gap between the classroom training environment and real-world construction sites; even trained personnel can find it difficult to recognize many of the potential safety hazards at their jobsites even after receiving construction safety training. Immersive technologies can overcome the current limitations in construction safety training by reducing the gap between the classroom and a real construction environment. This research developed and tested a new Augmented Reality (AR)-based assessment tool to evaluate the hazard recognition skills of students majoring in construction management as part of a construction safety course. The quantitative and qualitative results of this research confirmed that AR-based assessment can become a very effective assessment tool to evaluate safety knowledge and skills in a construction safety course, outperforming both paper and computer-based assessment methods. The students preferred AR-based assessment because it provides a realistic visual context for real world safety hazards.

  • The purpose of this study was to investigate the actual state of introduction and distribution of import apparel and to identify which characteristics of import apparels were different from domestic apparels by analysing consumer's evaluation attitudeto import apparels comparatively. Inaddition, by forming consumer groups who prefered import apparels and who prefered domestic apparels consumer characteristics and factors of each group were investigated. Results of this study are summarized as follows; 1. The degree of recognition of domestic or import well-known apparel brands were both high as 79.1% was to national brandcomparing with 77.0% of import brands. Average holding articles of import apparels were increasing up to 2.08 per person. 2. Consumers gave better evaluation to import apparel in all its aspects. With respects of the economic value and thepractical value, domestic apparel brands were evaluated better than import apparel brands while import apparel brands were evaluated better than domestic apparel brands with respects of design, brand image, and quality value. 3. Consumer group who has preference to import apparel has the tendency of high degree of clothing expenditure and low degree of economical behavior in clothing life st)4e and high degree of brand preferency. Futhermore, such group was not affirmative to negative effect of purchasing import goodsand open-trade policy. 4. Core factors affecting the preference to import apparel were design evaluation attitude, general reluctancy to buying imports, brand-oriented clouting life style, and degree of prossession of import apparel, as enumerated in the order of importance.

  • Recently the Supreme Court held that "in cases in which a patient suffering from a mental disorder attempts to commit suicide, fails, and then succeeds in a subsequent attempt, the following circumstances must be present in order to acknowledge reasonable causation between the negligence of the hospital with regards to taking care of the patient and the death of the patient; there must have existed negligence on the part of the hospital with regards to their failure to stop the 1stsuicide attempt, injurious aftereffects must have been caused to the patient by the1stsuicide attempt, and said aftereffects must have been the main cause for the 2nd successful suicide attemtp." This, in effect, lessens the requirements of past holdings of the Supreme Court which held that "to acknowledge reasonable causation between the negligence of the hospital and the patient that commits suicide, the patient must have experienced such severe physical and mental suffering from the previous attempt so that they could not help but choose to commit suicide". The fact that the Supreme Court did not clearly state such changes in their view on this matter should be corrected. Also, the fact that the court only held the hospital liable for damages of less than 50 million won, only calculating damages up to the point when the deceased passed, is inadequate compared to other cases and should be corrected.

  • Functional medicine is a system which utilizes certain investigative and treatment methods that are primarily oriented toward the recognition of functional disorder. Functional disorders take place on an energetic plane. This plane is not capturable using our regular investigatory techniques, such as X -ray. ultrasound, computer tomography and laboratory analyses. The 7-zone-diagnostic system(VEGA-DFM 722 and ABR-2000, etc) is a diagnostic device Which applies pulse signals to predetermined bodily locations. Applying alternating positive and negative stress to tissues with positive and negative pulses first manifests itself as negative and positive wave forms. The skin has many functions as an organ. It is the organism's interlace with the outsider world. Hence, the manner in which the skin reacts to external stimuli reflects the current state of the organism(as meridian systems). This system make a diagnosis of functional disorder or some typical organic diseases include stress of the mind or the body, and the energetic situation, reserves. We are known a disorder or disease throw the result chart. This result chart contain disorder flow wave forms and some valuable diagnostic hints (letters ; S, OM, RA, etc). In spite of this 7-zone-diagnostic system that is applied plentifully in the clinical application, there is not a statistics which is suitable. Therefor we must carry out many various research in the future.

  • Except the time when the relics of the museum are exhibited or loaned to the public, they are stored in a storage. Therefore, the environmental condition of a storage is a important factor. But in Korea, the appearance of the building and exhibition design are emphasized more than any other factors in planing museums, so the preservation technology has not yet reached the appropriate level and leaded to some environmental problem in the museum storage. The purpose of this study is to suggest guideline for an apt storage system by reconsidering practical notes in planning storage and give a efficient long-term plans examinable category. So this study based on the research had been stated from the recognition that the relics should be planned and placed differently in sorts, and developed this by researching the theory related to the matter throughout documents and to cope with the low efficiency in its essential role compared to the massive investment and through on-the-spot surveys emphasizing on the storage of the domestic museums in progress since 1995. Hereafter it compares the actual condition and problems of the domestic museum planning with the ones abroad, and analyzes the characteristic and difference between the two, and then establish an organized storage system.

  • The purpose of this study was to present a guideline for the construction of children park that can create a quality of dwelling and be easily approached and utilized by residents. In order to present a direction of planning, the investigator examined the actual state of children park in low-rise house residential area, and analyzed its general characteristics. And the discriminative characteristics according to the standpoints of planning of children park. The analytic standpoints were classified into the size and disposition of park, the nature of adjacent street and the utilization of park, and the satisfaction and requirement for the internal space of park. The guideline of planning of children park are as follow: (1) The disposition and size of children park: the children park must be disposed convenient use of all the residents. (2) The environment around including approaching streets and facilities around: residents' recognition and access in their everyday life must be considered in relation to the neighborhood streets and surrounding facilities. (3) The composition and utilization of internal space: the internal space must support all the activities of users, and reflect users' requirements in order to induce them to use it continuously.

  • The prediction of protein secondary structure has been an important bioinformatics tool that is an essential component of the template-based protein tertiary structure prediction process. It has been known that the predicted secondary structure information improves both the fold recognition performance and the alignment accuracy. In this paper, we describe several novel ideas that may improve the prediction accuracy. The main idea is motivated by an observation that the protein's structural information, especially when it is combined with the evolutionary information, significantly improves the accuracy of the predicted tertiary structure. From the non-redundant set of protein structures, we derive the 'potential' parameters for the protein secondary structure prediction that contains the structural information of proteins, by following the procedure similar to the way to derive the directional information table of GOR method. Those potential parameters are combined with the frequency matrices obtained by running PSI-BLAST to construct the feature vectors that are used to train the support vector machines (SVM) to build the secondary structure classifiers. Moreover, the problem of huge model file size, which is one of the known shortcomings of SVM, is partially overcome by reducing the size of training data by filtering out the redundancy not only at the protein level but also at the feature vector level. A preliminary result measured by the average three-state prediction accuracy is encouraging.
