  • In a vehicle-to-vehicle accident, the impact posture, braking status, final stopping position, collision point and collision speed are important factors for accident reconstruction. In particular, the speed of collision is the most important issue. In this study, the collision speed and the final stopping position in the tunnel were estimated using PC-CRASH, a vehicle crash analysis program used for traffic accident analysis, and the final stopping position of the simulation and the final stopping position of the traffic accident report were compared. When the Pride speed was 0km/h or 30km/h and the Sorento speed was 100m/h, the simulation results and reports matched the final stopping positions and posture of the two vehicles. As a result of the simulation, it can be estimated that Pride was collided in an almost stationary state.

  • In a car accident in Kyongju, each of the two occupants insisted that he was not driving the car. The accident was investigated to determine who the driver is through careful review of the collision report, the statements of accident and witness, photographs taken at the scene, and the expert report of the National Institute of Scientific Investigation. The accident was reconstructed based on the physical principles, injuries of occupants, damages of the involved vehicles and their final stops. A mistake was found in the expert report.

  • In order to treat edentulous patients with fixed implant prosthesis, the final prosthesis form should be predetermined based on the anatomic structures of the arch, the opposing dentition, and the occlusal plane. The design and occlusion of the interim prosthesis can provide useful information when fabricating the definitive prosthesis. In this case report, scan data of the edentulous region and the interim prosthesis were superimposed through an intraoral scanning digital workflow. In this way, the interim prosthesis information was incorporated into the design of the final prosthesis. Furthermore, the interim prosthesis data acquired through intraoral scanning was utilized to plan the positions and angles of the implants based on the final prosthesis design. Surgical guides were used to accurately place the implants in the planned three-dimensional positions. In this case report, satisfactory esthetic and functional clinical outcomes were achieved through application of digital techniques.

  • It is believed that geological survey, drilling and geophysical survey which was carried out on Tertiary deposits in Pohang is a valuable but through the studying of many Tertiary sediments in Japan discovered many questions on analysis of final report prepared by National geological survey. The main reason is: 1. The seismic sound velocity which have regulated in the final report prepared by geological survey for Tertiary deposits in Pohang was 1,500-2,000m/sec in spite of oil bearing sediments of same age in Japan are 2,000-3,800m/sec. These may means the requirement of reconsideration of seismic velocity for Tertiary deposits in Pohang and required to have a dipper drilling. 2. Stratigraphically, geophysically, and paleontologically, the Tertiary deposits in Pahang land area is similar with that of Nishiyama-Hunakawa formations of Akita oil field in Japan. Nishiyama-Hunakawa formation is the main oil bearing formation in Japan. 3. Those valcanic rock including andestitic rock and liparitic rock which have extensively distributed over either at land area or at sea bottom, assumed by geological survey as the base of Tertiary sediments. But in case of Japan many oil bearing deposits are in over laid by these kind of volcanic rock. Therefore a possible of same condition with Japan is presumable on Tertiary sediments in Pohang. 4. It is believed that the Tertiary sediments of land area in Pohang is the extension of offshore basin but is wandering that the final report submitted by geologic survey have not remain any word on report of ECAFE discribed so much problematics as followed: A. Although it was assumed that no great thickness exceeding 1,000 meters, or major structures would be encountered in the Tertiary offshore sequence, it was hoped that shallow hydrocarbon deposits might be found, because these sediment are lithologically similar to those of the same age in the producing area of the northwest Honshu region of Japan where hydrocarbon are extracted from depths of only 500 to 600 meters. B. Four possible hydrocarbon trap conditions are represented in the survey area: anticlinal folds, faults, pinch outs, along the igneous basement and lateral facies changes. C. Most of the prime possible reservoir area are beyond the 50 meter water depth mark, except for the structures in Yonil Bay. D. Despite the shallowness of the offshore basin, sufficient trap condition exist in the area to warrant further exploration for hydrocarbon. 5. All of the problems mentioned above have gave us a strong reasons to have us hesitating to make a final conclusion on Tertiary problems in Pohang, before to have a drill to a depth to 3,000 meters or more whatever it is the Tertiary or a Mesozoics below 1,000 meters.

  • Many references report that abnormal diastema except temporary diastema existing in mixed dentition period is caused by maxilary heavy labial frenum, malocclusion, progressive periodontal disease, and loss of posterior teeth. We can diagnose patient as diastema caused by periodontal disease, especially, in case of accompanying progressively destructed anterior maxillary alveolar bone defect, and interseptal bone defect. We report Multiple disciplinary approach for diastema associated with periodontal disease. Periodontal treatment(Guided Tissue -Regeneration, alveoloplasty, bone graft), or thodontic treatment (space closure, redistribution), and the final proshodontic restoration for retention were used.

  • The FDA guidance focuses on the use of the NOAEL to establish the maximum recommended starting dose. The majority of NOAEL has been described inaccurately or incompletely in final reports for 90-days repeated dose toxicity test based on GLP (good laboratory practice) regulation. This is the most serious one of reasons for why most pharmaceutical companies targeting global markets have disregarded the final report produced from GLP facilities in Korea. The problems in deciding NOAEL reflected in the final reports are mainly due to the followings; 1) Inaccurate description or use of NOEL, NOAEL and LOAEL, 2) Insufficient and inappropriate interpretations in findings from toxicity test. This paper is intended to provide the insight into distinguishing NOAEL from NOEL and LOAEL, and into classifying findings from toxicity test. Here, the three step method is newly suggested by applying the weight-based classification to the NOEL, NOAEL and LOAEL based on the findings.

  • The purpose of this study is to contribute to improving the efficiency of managing the database of the reports arising from the results of National R&D projects. To that end, the reports submitted by 49 agencies under the Ministry of Science and ICT were collected, and samples were selected for each institution. The samples and form of the final report and summary of the Enforcement Rule of the Framework Act on Science and Technology were compared, and the components and items to be entered were established. The final report's unique items were derived from the analysis of the state of connection with the National R&D information standard. The items to be entered are classified into major and optional according to their importance, and the location of the entry to be entered is suggested. If standardization of the elements and items is advanced as planned, it is expected to automate metadata extraction and improve the quality of report metadata when building a database.

  • This case report presents two maxillary anterior cases for clinical crown lengthening by forced eruption. In the first case, clinical crown of maxillary right lateral incisor was almost lost by fracture. Forced eruption using intracoronal splint and elastic thread accomplished vertical root movement successfully. Then, post & core was inserted and final restoration was harmonious with adjacent teeth. In the second case, the crown portion of maxillary right central incisor was almost mutilated by secondary caries. Forced eruption using removable Hawley appliance and elastic accomplished vertical root movement successfully. Then, post & core was inserted and final restoration was placed. In conclusion, clinical crown lengthening by vertical root movement can be accomplished by a simple appliance without any sacrifice of periodontal support in selected patients. A clinical crown so created can be restored to adequate function and arch integrity without compromising adjacent teeth. Therefore, forced eruption is preferred in the anterior region of the dentition where esthetics is of major concern.
