  • We analyzed food sources of 45 fish species in 28 genera of 12 families based on literature data in freshwater ecosystems of South Korea. The food sources of 45 fish species included in a total of 26 phyla, 42 classes, 94 orders, 189 families and 294 genera. Among them, animal food sources were 16 phyla, 24 classes, 54 orders, 126 families and 212 genera, whereas plant food sources were relatively small with 10 phyla, 18 classes, 42 orders, 63 families and 82 genera. The animal food sources were classified into Arthropod, Insecta, Diptera and Chironomidae according to taxa. Meanwhile, Bacillariophyta, Bacillariophyceae, Cymbellales and Cymbellaceae were the most abundant among the plant sources. Self-Organized Map (SOM) and network analysis were conducted the food sources were classified into taxonomic groups and the feeding types of fish : 45 fish species were divided into five groups, characterizing 1) fishvores, 2) invertebratevores, planktivores including 3) zooplankton and 4) phytoplankton, and 5) omnivores. The network analysis presented link association between fishes and food sources. Macroinvertebrate including diptera and ephemeroptera were revealed as hub food sources based on network analysis. This literature study would expect that the application model with the food source of fish could be utilized for the evaluation of the food network or chain in freshwater ecosystems.

  • One of the areas of second language acquisition that enjoyed popularity in recent years is interlanguage pragmatics. The main reason for this popularity lies in the critical role of pragmatic competence in appropriate use of a target language. The aim of this paper was to examine L2 learners' pragmatic behavior in their speech act performance and determine main sources causing pragmatic difficulty. Four major sources of pragmatic errors were identified: linguistic proficiency, L1 transfer, waffling and teaching activities. Each source was discussed with empirical evidence in some detail, and teaching suggestions were provided for developing learners' pragmatic competence in EFL classrooms.

  • The great flowing of information has brought a necessity for good management to make the best use of it in the highly competitive information age. The aims of this study are to investigate the main information sources - divided into largely three groups: literature sources, communication and information technology facilities), trying to find problem areas associated with IRM, indicating possible solutions. The result shows that internal information sources were regarded the most important and most frequently used. For the use of foreign materials, the higher the level of position is, the more people use them. With respect to communication methods, internal information sources were thought most important. With the dramatic falling of the price despite enormously increased functions, IT facilities are becoming important sources. However, the study reveals the use of them is quite limited to a few well-known facilities, which indicates that management should pay attention to more efficient use of them and useful training and education methods.

  • This study was conducted with a view to investigating and analyzing classification and types of literature sources of Sikuquanshuzongmutiyao and the results of this study are as follows. First, the literature sources of Sikuquanshuzongmutiyao were classified mainly into five types including national version, provincial version, individual version, public official version, and societal distribution version. Second, court and Emperor's version was classified as national version, while literatures collected from state and province were classified as provincial version. Third, each of individual version and public official version, which were not clearly differentiated from each other due to their being named private version, were distinctively and separately classified. They were classified into individual version if associated by province name and book owners' names and into public official version if associated by public post names and public official's name. Fourth, societal distribution version included distributed and purchased versions in the society of those days. Fifth, in terms of the number of literature listed in all descriptions of Sikuquanshu, provincial version, national version, individual version, public official version, and societal distribution version were more found in the descending order. Sixth, it was found out that causes are being a little more stressed in the description of reference names of Sikuquanshuzongmutiyao through 1) public post names on public official version, 2) company names on private version, and 3) names of societal distribution version instead of sales version.

  • The current research presents a detailed methodology for generating air blast loading for use within a finite element context. Parameters describing blast overpressure loading on a structure are drawn from open literature sources and incorporated within a blast load generation computer code developed for this research. This open literature approach lends transparency to the details of the blast load modeling, as compared with many commonly used approaches to blast load generation, for which the details are not publicly available. As a demonstration, the load generation code is used with the finite element software LS-DYNA to simulate the response of a steel plate and girder subjected to explosions modeled using these parameters as well as blast parameters from other sources.

  • Game contents are the driving force of the digital media era. As the gaming industry grows bigger, contents technologies are also rapidly developing in both their quality and quantity, while the story sources of the contents are depleting. Accordingly, digging out new stories that can support development of the cultural contents industry is emerging as an urgent issue. Since games took roots as a form of contents in our society, negative images have outweighed positive aspects. This study aims at finding cures for the side effects from storytelling. Important factors here are how to converge the technical nature of engineering imagination and the epic nature of humanities imagination. Recently, The excavations of the story is very important. This article demonstrates cases where the oral literature, an archetypical cultural genre, provides the sources of game storytelling.

  • Peninsular Malaysia lying on the stable Sunda Plate has traditionally been considered safe with low to moderate seismicity. However, far field Sumatran mega-earthquakes have been shown to be capable of triggering ground motions felt in high rise structures in the major Malaysian cities while seismic impact from local earthquakes of moment magnitude 3.8 have reportedly induced nominal structural damages to nearby buildings. This paper presents an overview of the recent seismic activities in and around Peninsular Malaysia with reference to prominent earthquakes generated by far field interplate and local intraplate sources. Records of ground motion data and seismic hazard assessment (SHA) results available in the literature have been analyzed and discussed. The peak ground acceleration (PGA) values from historical records for few local intraplate events were observed to be higher than those for the events from Sumatran Subduction Zone. This clearly points to the need for a detailed and comprehensive SHA incorporating both far field and local sources. Such an analysis would contribute the knowledge required for secure and reliable infrastructure design and safeguard the Malaysian people and economy.

  • Kidney and liver are the major organs of metabolism and excretion of drugs. Renal and Hepatic impairment may affect the pharmacokinetics/pharmacodynamics and the safety of drugs. Adjusting the dosage based on organ function is the essential role of pharmacists. However, differences have been noted on the recommended dosage among the literatures. We compared and analyzed the recommendations of 4 literature sources which are commonly used for dosage adjustment. From April, 2011 to August, 2011, we selected data on recommendations for dosage adjustment for impaired renal and hepatic function of 100 drugs through a protocol. We analyzed the definition terms of renal and hepatic impairment, recommendations for dosage adjustment, evidenced references in four literature sources: Korean National Formulary (KNF), American Hospital Formulary System Drug Information (AHFS), Micromedex (MM) and Drug Prescribing of Renal Failure (DPRF). We further examined the data homogeneity by comparing how drugs that required no adjustment according to one source were categorized by the other. Sources use different definition terms among themselves except DRPF. Presence or absence of evidenced references about renal/hepatic functional states are KNF (0%/0%), AHFS (78%/62.6%), MM (87.5%/65.6%) and DPRF (93.2%/no recommendation) respectively. Recommendations of specific dosage and dosing interval are KNF (24%/13%), AHFS (39.6%/12.1%), MM (50%/17.7%), and DPRF (55.4%/no recommendation) respectively. Regarding the data homogeneity, the differences were remarkable. Drugs with no adjustment according to AHFS were categorized to be adjusted/ contraindicated by KNF, MM, DPRF and the values were (44%/5.6%), (22%/0%), and (36%/0%) in renal function, (39%/6.5%), (19%/3.2%), and (no recommendation/no recommendation) in hepatic function respectively. Our study shows remarkable definite variation in definitions and recommendations about definition terms, information of dosage and interval, presence or absence of evidenced references. Especially for KNF, quantitative recommendations on dosages and dosing intervals should be made in the near future. To maximize the drug effect and safety and to minimize the heterogeneity of the literature sources, reviewing at least two sources are suggested when recommending the proper dosage adjustment based on organ function.
