The number of phishing/pharming attacks occurring has increased and consequently, the number of studies on anti-phishing/pharming has also increased. The target sites of phishing/pharming are financial sites, and these have a low connection rate compared to those of portal sites. In this paper, we propose an anti-phishing/pharming method that uses a portal site as a stopover. The proposed method is based on the reliability of portal sites. This method is intended for general users rather than for professional users or developers. We also analyze the safety of the proposed method by separating the method into sub components of module safety assumption.

A criminal liability of the divisional medical-institution is faced a new aspect in the connection with development of the medical techonology. Especially, a division of labor in the medical-institution in Korea will be greatly increased in the foreseeable future. A general hospital will be frequently confronted with sofisticated techniques such as MRI, CT-screen. Accordings to the nature of its functions, a general hospital may make accommodation or services or both available for patients who give undertakings (or for whom undertakings are given) to pay, in respect of the accommodation or services (or both) such charges as the government may determine. It shall be the duty of the government to develop, promote and regulate a criminal liability of the divisional medical-institution. Above all, the government shall have to determine the standard of a criminal liability of the medical-institution in the horizontal specialization and the vertical specialization. But, the court may give finally by directions the standard of the criminal liability of the divisional medical-institution.

This study aims to develop some guidelines on visiting nursing services for the management of hypertension patients at home in the rural areas of Korea. Firstly, in-depth interviews were given to the eight staff in charge of visiting nursing services in the rural health centers from June 1, 1999 to August 30, 1999. And then, their five patients with hypertension were under participatory observation. At the same time, literature review was conducted. Through those methods, some preliminary items were derived and the initial guidelines were drawn up. They were referred to ten experts, so that their validity was tested with Delphi Technique. Through the verification of their validity, they were complemented into the final ones. The total number of the items in the final guidelines was 22. By areas, they could be categorized as follows; eight items as skilled nursing care, five as general nursing care, three as guidance for diet, two as guidance for exercise, one as hospice care, and one as connection with social welfare services. By methods of activities, 13 items were classified as assessment, two as intervention, two as demonstration, and 17 as explanation. On the basis of the guidelines, nursing services are recommended to be divided and performed; general nursing activities by nurse aids and skilled nursing activities by public health nurses.

In recent, interests regarding open source software for geo-spatial processing are increasing. Open source remote sensing (OSRS) is regarded as one of the progressing and advanced fields in remote sensing. Nevertheless, analyses or application cases regarding OSRS are not enough for general uses or references. In this study, three kinds of OSRS software in consideration of international popularity, types of functionalities, and development environments are taken into account: OSSIM, Opticks, and ORFEO Toolbox (OTB). First, functional comparison with respect to these is carried out on the level of the preliminary survey. According to this investigation, OTB is chosen as the most applicable OSRS software in this study. Running on OTB, NIX format importing module and database connecting module are implemented for widely general uses and further application. As for an example case, airborne image of NIX format is used to region growing segmentation algorithm in OTB, and then the results are stored and retrieved in PostGIS database to test implemented modules. Conclusively, local customization and algorithm development using OSRS software are necessary to build on-demand applications from the developers' viewpoint.

Russian State Historical Archive (Rossiiskii gosudarstvennyi istoricheskii arkhiv - RGIA) received its present name in June 1992, and before 1961 was known as TsGIA. RGIA holds the major records of high-level and central state and administrative institutions and agencies of tsarist Russia from the eighteenth century to 1910s (except the records of the Army, Navy, and the Ministry of Foreign Affairs), as well as fonds of social organizations, institutions, and individuals of prerevolutionary Russia. The main goal of this article is to assist understanding russian principle on arrangement and classification archives with its historical development focusing on one of the biggest historical archive in Russia. The primary set of historical records in RGIA remain arranged in 3-steps classification system: fond (collection) -- opis' (inventory) -- delo (file). In this general survey of RGIA author offers detailed information on the collection of archives and the system for classification of its huge amounts of primary sources in connection with influence upon historical studies. Despite the general economic crisis Russian archives are struggling to keep their doors open for public research and are exerting their energies in present electronic information to scholars and other researchers from throughout the world. The result, however, is not rewarded enough, considering the effort involved.

Background: This study used text mining techniques to determine public perceptions of dental fear, extracted keywords related to dental fear, identified the connection between the keywords, and categorized and visualized perceptions related to dental fear. Methods: Keywords in texts posted on Internet portal sites (NAVER and Google) between 1 January, 2000, and 31 December, 2022, were collected. The four stages of analysis were used to explore the keywords: frequency analysis, term frequency-inverse document frequency (TF-IDF), centrality analysis and co-occurrence analysis, and convergent correlations. Results: In the top ten keywords based on frequency analysis, the most frequently used keyword was 'treatment,' followed by 'fear,' 'dental implant,' 'conscious sedation,' 'pain,' 'dental fear,' 'comfort,' 'taking medication,' 'experience,' and 'tooth.' In the TF-IDF analysis, the top three keywords were dental implant, conscious sedation, and dental fear. The co-occurrence analysis was used to explore keywords that appear together and showed that 'fear and treatment' and 'treatment and pain' appeared the most frequently. Conclusion: Texts collected via unstructured big data were analyzed to identify general perceptions related to dental fear, and this study is valuable as a source data for understanding public perceptions of dental fear by grouping associated keywords. The results of this study will be helpful to understand dental fear and used as factors affecting oral health in the future.

Two-layer coupled or composite beams with discrete shear connectors of finite dimensions are commonly encountered in pre-fabricated construction. This paper presents the development of simplified closed-form solutions for such type of coupled beams for practical applications. A new coupled beam element is proposed to represent the unconnected segments in the beam. General solutions are then developed by an inductive method based on the results from the finite element analysis. A modification is subsequently considered to account for the effect of local deformations. For typical cases where the local deformation is primarily concerned about its distribution over the depth of the coupled beam, empirical modification factors are developed based on parametric calculations using finite element models. The developed analytical method for the coupled beams in question is simple, sufficiently accurate, and suitable for quick calculation in engineering practice.

In this paper, Rigid Reinforced Roadbed(RRR) which is expected to have highly applicability to railroad roadbed, was introduced and field tests results were analyzed. Full scale model with 5m height concerning a single track railroad roadbed was constructed. The model had four different sections, which was to assess the effect of geogrid length, spacing, and connection method on deformation characteristics of RRR. Laser displacement meter, earth pressure cell, piezometer, and strain gauge were installed in order to analyze the behavior of reinforced embankment during construction. Horizontal displacements caused by compaction at each section were 20~30% below the displacement limit that of general reinforced retaining wall, which showed that RRR was very stable structure. Maximum tensile strength of reinforcement was withing 10% of the long-term design strength.
