  • Procedures play a key role in ensuring safe operation at nuclear power plants (NPPs). Development and maintenance of a large number of procedures reflecting the best knowledge available in all relevant areas is a complex job. This paper introduces a newly developed methodology and the implemented software, called iExtractor, for the extraction of syntactic and semantic information from NPP procedures utilizing natural language processing (NLP)-based technologies. The steps of the iExtractor integrated with sets of rules and an ontology for NPPs are described in detail with examples. Case study results of the iExtractor applied to selected procedures of a U.S. commercial NPP are also introduced. It is shown that the iExtractor can provide overall comprehension of the analyzed procedures and indicate parts of procedures that need improvement. The rich information extracted from procedures could be further utilized as a basis for their enhanced management.

  • This paper presents a method for estimating the useful output of solar space heating system and estimates their performance with variance of collector size, storage volume, collector tilt and other factors . The analysis is performed by the computer simulation and by 'running' conceptual systems against solar intensities and ambient temperature for a model year stored in a computer. System performance is analyzed on monthly and yearly basis respectively and at the same time, the economics of various systems are evaluated . And also, this paper shows how an optimized design can be selected for any locality for which solar data, economic parameters and system performance are provided. It is shown that storage volume of 75 liter per $m^2$ of solar collector lead to the best design.

  • The Coronary Artery Disease Reporting and Data System (CAD-RADS) is a standardized reporting method for coronary computed tomography angiography (CCTA). It summarizes the findings of CCTA in 6 categories ranging from CAD-RADS 0 (complete absence of coronary artery disease) to CAD-RADS 5 (total occlusion of at least one vessel). It is applied on per patient basis for the highest grade of the stenotic lesion. The CAD-RADS also provides categoryspecific treatment recommendations, helping patient management. The main objectives of the CAD-RADS are to improve the consistency in reporting, facilitate the communication between interpreting and referring clinicians, recommend the best course of patient management, and produce consistent data for quality improvement, research and education. However, CAD-RADS has many limitations, resulting into the misclassification of the observed findings, misinterpretation of the final category, and misguidance for the treatment based upon the single score. In this review, the authors discuss the CAD-RADS categories and modifiers, along with the strengths and limitations of this new classification system.

  • The increasing functional needs of top-quality printing papers and packaging paperboards, and especially the rapid developments in electronic printing processes and various computer printers during past few years, set new targets and requirements for modern paper quality. Most of these paper grades of today have relatively high filler content, are moderately or heavily calendered , and have many coating layers for the best appearance and performance. In practice, this means that many of the traditional quality assurance methods, mostly designed to measure papers made of pure. native pulp only, can not reliably (or at all) be used to analyze or rank the quality of modern papers. Hence, introduction of new measurement techniques is necessary to assure and further develop the paper quality today and in the future. Paper formation , i.e. small scale (millimeter scale) variation of basis weight, is the most important quality parameter of paper-making due to its influence on practically all the other quality properties of paper. The ideal paper would be completely uniform so that the basis weight of each small point (area) measured would be the same. In practice, of course, this is not possible because there always exists relatively large local variations in paper. However, these small scale basis weight variations are the major reason for many other quality problems, including calender blacking uneven coating result, uneven printing result, etc. The traditionally used visual inspection or optical measurement of the paper does not give us a reliable understanding of the material variations in the paper because in modern paper making process the optical behavior of paper is strongly affected by using e.g. fillers, dye or coating colors. Futhermore, the opacity (optical density) of the paper is changed at different process stages like wet pressing and calendering. The greatest advantage of using beta transmission method to measure paper formation is that it can be very reliably calibrated to measure true basis weight variation of all kinds of paper and board, independently on sample basis weight or paper grade. This gives us the possibility to measure, compare and judge papers made of different raw materials, different color, or even to measure heavily calendered, coated or printed papers. Scientific research of paper physics has shown that the orientation of the top layer (paper surface) fibers of the sheet paly the key role in paper curling and cockling , causing the typical practical problems (paper jam) with modern fax and copy machines, electronic printing , etc. On the other hand, the fiber orientation at the surface and middle layer of the sheet controls the bending stiffness of paperboard . Therefore, a reliable measurement of paper surface fiber orientation gives us a magnificent tool to investigate and predict paper curling and coclking tendency, and provides the necessary information to finetune, the manufacturing process for optimum quality. many papers, especially heavily calendered and coated grades, do resist liquid and gas penetration very much, bing beyond the measurement range of the traditional instruments or resulting invonveniently long measuring time per sample . The increased surface hardness and use of filler minerals and mechanical pulp make a reliable, nonleaking sample contact to the measurement head a challenge of its own. Paper surface coating causes, as expected, a layer which has completely different permeability characteristics compared to the other layer of the sheet. The latest developments in sensor technologies have made it possible to reliably measure gas flow in well controlled conditions, allowing us to investigate the gas penetration of open structures, such as cigarette paper, tissue or sack paper, and in the low permeability range analyze even fully greaseproof papers, silicon papers, heavily coated papers and boards or even detect defects in barrier coatings ! Even nitrogen or helium may be used as the gas, giving us completely new possibilities to rank the products or to find correlation to critical process or converting parameters. All the modern paper machines include many on-line measuring instruments which are used to give the necessary information for automatic process control systems. hence, the reliability of this information obtained from different sensors is vital for good optimizing and process stability. If any of these on-line sensors do not operate perfectly ass planned (having even small measurement error or malfunction ), the process control will set the machine to operate away from the optimum , resulting loss of profit or eventual problems in quality or runnability. To assure optimum operation of the paper machines, a novel quality assurance policy for the on-line measurements has been developed, including control procedures utilizing traceable, accredited standards for the best reliability and performance.

  • Background: Breast cancer is a worldwide public health concern and is the most prevalent type of cancer in women in the United States. This study concerned the best fit of statistical probability models on the basis of survival times for nine state cancer registries: California, Connecticut, Georgia, Hawaii, Iowa, Michigan, New Mexico, Utah, and Washington. Materials and Methods: A probability random sampling method was applied to select and extract records of 2,000 breast cancer patients from the Surveillance Epidemiology and End Results (SEER) database for each of the nine state cancer registries used in this study. EasyFit software was utilized to identify the best probability models by using goodness of fit tests, and to estimate parameters for various statistical probability distributions that fit survival data. Results: Statistical analysis for the summary of statistics is reported for each of the states for the years 1973 to 2012. Kolmogorov-Smirnov, Anderson-Darling, and Chi-squared goodness of fit test values were used for survival data, the highest values of goodness of fit statistics being considered indicative of the best fit survival model for each state. Conclusions: It was found that California, Connecticut, Georgia, Iowa, New Mexico, and Washington followed the Burr probability distribution, while the Dagum probability distribution gave the best fit for Michigan and Utah, and Hawaii followed the Gamma probability distribution. These findings highlight differences between states through selected sociodemographic variables and also demonstrate probability modeling differences in breast cancer survival times. The results of this study can be used to guide healthcare providers and researchers for further investigations into social and environmental factors in order to reduce the occurrence of and mortality due to breast cancer.

  • In der vorliegenden Arbeit wird die $M\"{o}glichkeit$ der Unterklassifikation des Sprechakttyps untersucht. Zur Klassifikation von Sprechakten hat Searle (1969) $zw\"{o}lf$ Kriterien vorgeschlagen, und mit den folgenden drei Kriterien hat er funf Sprechaktklassen herausgearbeitet: $illokution\"{a}rer$ Zweck, Entsprechungsrichtung und psychologischer Zustand. Bei der Unterklassifikation dieser $f\"{u}nf$ Sprechaktklassen $k\"{o}nnen$ aber die von Searle vorgeschlagenen Klassifikationskriterien kaum gebraucht werden, so dass zur Unterklassifikation jeder Sprechaktklasse neue Kriterien $eingef\"{u}hrt$ werden mussten. Dabei stellt sich die Frage, was als Unterklassifikationskriterien dienen und wie ausdifferenziert eine Spreckaktklasse bzw. ein Sprechakttyp unterklassifiziert werden kann. Im 1. Kapitel werden neben den Klassifikationskriterien von Searle die Kriterien, die in den bisherigen Unterklassifikationen der Sprechaktklassen verwendet wurden, kritisch betrachtet. Im 2. Kapitel wird auf die Frage der Ausdifferenzierungsgrenze $n\"{a}her$ eingegangen, wobei diskutiert wird, ob die Unterklassifikation der Fragehandlung von Hindelang (1981) und die des Insistierens von Franke (1990) genugend ausdifferenziert sind oder es noch $M\"{o}glichkeiten$ besteht, sie noch weiter auszudifferenzieren. Die Frage nach der Ausdifferenzierungsgrenze ist mit der Frage gleichzusetzen, inwieweit eine Sprechhandlung ohne Verlust ihres Handlungscharakters in Untertypen zerlegt werden kann. Um diese Frage zu beantworten, wird der Begriff 'Basishandlung' $eingef\"{u}hrt$, den von Wright (1974) im Rahmen seiner Theorie der Kausalitat entwickelt hat. In Analogie zu diesem Begriff wird der Begriff 'Basis-Sprechhandlung' vorgeschlagen und wie folgt definiert: 1. Obere Grenze: Eine Basis-Sprechhandlung ist die Sprechhandlung, die nicht durch den Vollzug der anderen Sprechhandlungen ausgefuhrt werden kann. 2. Untere Grenze: Durch eine $\"{A}u{\ss}erung$ bzw. einen Teil der $\"{A}{\ss}erung$ kann nur dann eine Basis-Sprechhandlung vollzogen werden, wenn sieler eine $\"{A}nderung$ des Wissens oder der Handlung des $H\"{o}rers$ $herbeif\"{u}hrt$. Diese These wird anhand der Beispiele $\"{u}berpr\"{u}ft$, deren kommunikative $Selbst\"{a}ndigkeit$ schon durch andere Studien $best\"{a}tigt$ wurde. Als weiteres Kriterium zur Entscheidung $\"{u}ber$ die $M\"{o}glichkeit$ der Unterklassifikation wird im 4. Kapitel der Begriff 'kommunikativer Zweck' $eingef\"{u}hrt$ und $dar\"{u}ber$ diskutiert, wie der kommunikative Zweck der Untertypen einer Sprechaktklasse bzw. eines Sprechakttyps definiert und beschrieben werden kann. Dabei wird festgestellt, dass er durch die Spezifizierung des kommunikativen Zwecks der Sprechaktklasse bzw. des Sprechakttyps, zu der/zu dem die Untertypen $geh\"{o}ren$, definiert und beschrieben werden kann, wobei die semantischen, die kontextuellen und die sitiativen Aspekte $mitbe\"{u}cksichtigt$ werden sollen.

  • The guide line of the SFRC mix design was not established, and the convenience of the practical application on the spot is not so good. In this paper, hence, the program which is optimized to result the mix proportion by the flexural strength and toughness, was developed to apply to SFRC on the practical spot. This program could minimize the number of trial mixes and get an economical and appropriate mixture. In addition, the theoretical background on which the program is based, will be the basis of the embodied method to mixing SFRC. Additionally, new algorithm, in this paper, was used to develop the mix proportioning program of SFRC. The new algorithm is the Harmony Search which is the heuristic method mimicking the improvisation of music players, Musical performances seek a best state determined by aesthetic estimation, as the optimization algorithms seek a best state determined by objected function value. And, it was developed the program about single fiber reinforced concrete, beside to the hybrid fiber reinforced concrete that two kinds of steel fibers, which have the different geometry, was reinforced. This will be able to keep the world trend to study, hence, offers the basis of the next research about hybrid fiber reinforced concrete.

  • Tuna and tuna fishing extend over most of the tropical waters of the world oceans, especially, this study of the Indian Ocean and the fish and the fishing vessels are highly mobile. No country can deal in isolation with the problems of its tuna fishery and of any tuna fishery in its waters, without collaborating with other countries. This cooperation is often best established through some formal international mechanism. The essential requirements are for information-on the resources, the fishery, the trade-and to identify where management actions are needed to consore the resources or to maintain the economic or social function of the fishery. These will also usually require some form of international mechanism. With the changes in the Law of the Sea, the siuuation in respect of management of tuna-considered among the highly migratory species, requirng special treatment-has also changed. At present there are both uncertainty regarding tuna management and political arguments as to how such management can be best implemented. Bearing this in mind, together with the fact that only few tuna stocks have shown clear evidence of serious depletion through over-exploitation, present emphasis will be placed on information requirements. This study included compiling the data necessary to review the state of stoks in the Indian Ocean tuna fishing grounds. Information on the resources-where the fish are, their quantity, their movements, etc. is important, whether in planning development of new fisheries, or considering the need for collaboration with other countries (in ascertaining to what extent their catches may affect catches of the natoinal fleet) or for conservation measures. A major source of information is the statistics of for conservation measures. A major source of information is the statistics of catch and fishing effort from existing commercial vessels. These need to be assembled for all fisheries on the same stock on an oceanwide basis. The statistical data also need to be analysed and intepreted, and combined with biological data(e.g., on growth, mortality and migration rates) to provide information that is intelligible and useful for administrators and other decision-makers. This must also be undertaken on a resource-wide or ocean-wide basis. Finally, because of the world-wide similarities in the methods of datching, processing and marketing fish, there is a particular tut not exclusive need in those countries just beginning to develop their tuna fisheries-to have ready access to a syntheis of information on tuna, tuna biology and tuna fisheries and tuna fisheries economics and management on the Indian Ocean.

  • Objectives : Korean medicine practice is not specifically described in medical law, and then has always been a quarrel. So far The criteria for judgment in Korean Medicine Doctor's Medical Devices Using should clinically prove it only by Korean medicine theory and academic Traditionally descending from old ancestors. Comprehensively review of Korean Medicine Doctor's Medical Devices Using and Duty of Care, and then present a new understandings to determine future Korean Medicine Practice. Method : An existing court cases of Korean Medicine Doctor's Medical Devices Using and Duty of Care were reviewed. After reviewing various papers published for several years, various opinions were reviewed and suggested. Results : The range of Korean Medicine Doctor's Medical Devices Using has changed since the 1951 National Medical Law stipulated Korean medicine as medical professionals. The issue of the recent ruling that distinguishes medical practice from Korean medicine practice were condensed into what emphasis to interpret amongst 1) The basic principles of learning, 2) Curriculum and professionalism, 3) Risks. The Constitutional Court's ruling was important in order of 'Risk', 'curriculum and expertise', and 'basic principles of learning.' A duty of Care means an obligation to pay attention to something. A duty of Care does not mean a "highest level," but requires a "best care" and does "best under given conditions." Even in the duty of Care, Because Korean medicine has a purpose to protect and promote the health of the people, Some standards of western medicine have to be adapted to the current general medical technology. Korean Medicine doctors can recognize the duty of care in the "some basic range" of knowledge belonging to western medicine. Conclusions : The interpretation of Korean Medicine practice are currently in compatible the argument that should clearly divide Korean medicine from Western medicine, and that should be changed in light of the changing medical environment. Therefore If Korean medicine's standard is applied to the extent to which Korean Medicine doctors are educated, it is necessary to define a new definition to actively interpret Korean Medical practice. The academic basis of Korean medicine and the level of Korean medicine practice based on the books that are traditionally available, and then current textbooks of Korean Medicine College, Korean Medicine Clinical Care Guidelines, and classification of Korean standard medical practices should be standardized. Increasingly, Korean Medicine practice should be interpreted according to reality, focusing on protecting and promoting the health of the people rather than academic differences.

  • The study was basically carried out to establish the appropriate condition for applying the Westergren method for erythrocyte sedimentation rate(W-ESR) in Throughbred racehorses at recess. To do this, we examined the correlationship among some factors including the kind of anticoagulants, optimal ambient temperature and reading time for W-ESR in healthy racehorses. The difference between the blood samples treated with only 3.8% solution of sodium citrate(SC) and both EDTA and SC as a coagulant, there was not recognized any significant difference(p<0.05) in the levels of W-ESR irrespective of the ambient temperature of $20^{\circ}C$ or $30^{\circ}C$. The best optimal ambient temperature for W-ESR in horses was proved at $30^{\circ}C$ resulting from the tendency of the most reduced dispersion in mean values analyaed from repeatly 4 times to the same blood samles compared with those of $10^{\circ}C$ and $20^{\circ}C$. The optimal reading time was determined as 60 minutes(Y=237.2~4.1X, $r^2=0.998$) and 70 minutes(Y=247.8~4.2X, $r^2=0.999$) under the same temperature of $30^{\circ}C$; the latter showed the better result on the basis of the correlation of packed cell volume(PCV) and ESR values. About 13 healthy racehorses, we compared the real values of W-ESR respectively obtained at 60 minutes and 70 minutes at $30^{\circ}C$ with the anticipated values of PCV by means of the analysis of linear regression equitation. As the result of this, the strong correlation between both of them was confirmed. For practical use of W-ESR in Thoroughbred racehorese, we can recommend the condition of 60 or 70 minutes for the optimal reading time as well as $30^{\circ}C$ for the best ambient temperature.
