This paper presents a vital area identification (VAI) method based on the current fault tree analysis (FTA) and probabilistic safety assessment (PSA) techniques for the physical protection of nuclear power plants. A structured framework of a top event prevention set analysis (TEPA) application to the VAI of nuclear power plants is also delineated. One of the important processes for physical protection in a nuclear power plant is VAI that is a process for identifying areas containing nuclear materials, structures, systems or components (SSCs) to be protected from sabotage, which could directly or indirectly lead to core damage and unacceptable radiological consequences. A software VIP (Vital area Identification Package based on the PSA method) is being developed by KAERI for the VAI of nuclear power plants. Furthermore, the KAERI fault tree solver FTREX (Fault Tree Reliability Evaluation eXpert) is specialized for the VIP to generate the candidates of the vital areas. FTREX can generate numerous MCSs for a huge fault tree with the lowest truncation limit and all possible prevention sets.

Purpose: Variation in the morphology of gingival papilla may be determined by the shape and position of anatomic crown as well as contact area and embrasure form of individual teeth. However, periodontal biotype classification is regarded to be subjective because of the lack of definite criteria. In this study, we defined the objective parameters which constitute the periodontal biotype and measured their relationship. Materials and Methods: 109 of dental casts were prepared using three dimensional scanner and specialized reconstruction software, then acquiredvirtual models were sent to the 20 professional dentists to define the specific periodontal biotypes. Several parameters around periodontal structures were measured from the virtual models; facial surface area of the anterior tooth (AT), anterior papillary area (AP), proportion of the dento-papillary complex, clinical papillary length (PL), and clinical papillary angle (PA). Statistical analysis was performed to confirm the relationship among parameters. Results: Coincidence rate of periodontal biotype within observers was $63.77{\pm}16.05%$. Coincidence rate between observers was $76.15{\pm}16.43%$. Among the parameters measured, PL showed the most positive correlations and PA presented the most negative correlations. The parameter of the AP and PL of six maxillary anterior teeth showed significant correlation coefficient. Conclusion: Anterior papillary area and clinical papillary length would be objective parameters for determining the consistent periodontal biotypes.

This study clarifies the theoretical background and the floor plan characteristics of component schools in Small Schools Complexes. The recent researches have proved the enhancement of students' social relationship and school security in the new school environment. The findings fur the characteristics by analyzing the component schools from six school complexes follow: (1) Students can access their classrooms in component schools through main entrances, shared corridors and private corridors. (2) Teachers' area is segregated from students' area, which does not encourage the social relationship between teachers and students. (3) Some of special classrooms, which are generally considered as shared facilities in a Small Schools Complex, are planned within component schools for accommodating specialized educational programs. (4) A component school occupying multiple floors reduces Intelligibility of space and chances of users' visual contact to colleagues. Finally, this study proposed the alternative floor planning directions in order to improve users' social relationship in a component school.

Since multipath phenomenon frequently occurs when a Global Positioning System receiver is placed in urban area crowded with large buildings, efficient mitigation of multipath effects is necessary to resolve. In this paper, we propose a new multipath detection technique that is useful in real-time positioning with a general Global Positioning System receiver. The proposed technique is based on a channelwise multipath test statistic that efficiently indicates the degree of fluctuations induced by multipath error. The proposed multipath test statistic is operationally advantageous because it does not require any specialized hardware nor any pre-computation of receiver position, it is directly related to standard $\chi$$^2$-distributions, and it can adjust the detection resolution by increasing the number of successive measurements. Simulation and experiment results verify the performance of the proposed multipath detection technique.

Purpose: Regional public hospitals have implemented functional reinforcement projects, and the facilities to accommodate them have increased in size. Nevertheless users in hospital are concerned about space shortage and area imbalances. Therefore I will trace the factors and trends that influence the size, and derive the relationship between these and the uses' critical opinion. Methods: Among the indicators for determining the size of medical facilities, the number of beds and total floor area are the essential indicators that directly affect the composition of space and allocation of area inside the medical facility. The purpose of this study is to investigate the change and the factors of change on the these two indicators in regional public hospitals and analyze the trend of changes. Results: In accordance with support undertaking, regional public hospitals have been increased the number of chronic-based beds and expanded additional facilities such as O.P.D specialized centers, emergency centers and funeral homes for reflecting the needs of the regions and times. However, as a result of analyzing the area, regional public hospitals are growing in size mainly on the ward and O.P.D is only expanded the scope of functional reinforcement division but total area level of O.P.D is lower than the recent level. In addition, the levels of D&T, Supply, mechanical/electrical equipment area related to medical support and control environment quality are very low. This is because the functional reinforcement projects have been done without concerning diagnose the whole facility. Implications: If functional reinforcement projects are conducted, to cope with problems of space shortage and imbalance of area, it is judged that an architectural planning that comprehensively analyzes existing facilities and related departments should be included.

Background: Korea's primary care clinics are seeking increase in consultation fees by expanding supply within the frame of the health insurance system, but inequality of physician income between regions and individuals is exacerbating. The purpose of this study lies in analyzing the distribution of patients of primary care clinics, their specialized field, and the degree of inequality between medical fee income according to region. Data was acquired from the Health Insurance Review and Assessment Service on charged bills made by clinic-size medical institutions from 2008 to 2011. Methods: By comparing the outpatient number per clinic according to the clinic's specialized field, results showed that ophthalmology, otolaryngology, dermatology, orthopedics, and internal medicine showed high numbers whereas plastic surgery, neuropsychiatry, cardiothoracic surgery had fewer outpatients. The number of outpatients for clinic according to region showed Chuncheonnam-do, Jeju-do, Gangwon-do, Chungcheongbuk-do, Ulsan to have higher numbers of outpatients. For those four years, clinics in the Seoul area had a rather lower number. Results: As a result of comparing the decile hierarchy distribution ratio between specialized fields according to primary care clinics income from National Health Insurance, the inequality degree showed that obstetrics and gynecology and general medicine were each 0.130, 0.280 for the decile distribution ratio, which was the highest degree of inequality within the specialized field. Their Gini coefficient were also relatively high at 0.691, 0.528 respectively. On the other hand, the decile distribution ratio for otolaryngology and orthopedics were 0.510, 0.468, respectively, while their Gini coefficient each at 0.318, 0.314 makes their inequality degree relatively lower than other fields. Conclusion: This study is limited in that the data used was the health insurance charges submitted by clinics, which does not provide total information of the doctors' income. However, because most clinics are largely dependant on their income to come from health insurance reimbursements. Therefore, the results of this study can be used effectively. In the future, research that includes data on non-covered service income should be conducted to closely examine policy plans with a new medical fee policy which can resolve the medical fee income inequality issue between clinics as well as revitalize primary medical care.
