  • Since too much information has been generated, it became very difficult to find out valuable and necessary information. In order to deal with the problem of information overload, the taxonomy for information visualization techniques has been based upon visualized shapes such as tree map, fisheye view and parallel coordinates, so that it was difficult to choose the right representation technique by data characteristics. Therefore, this study was designed to introduce a new taxonomy for the information visualization by data characteristics which defined by space (3D vs. multi-dimensions), time (continuous vs. discrete), and relations of data (qualitative vs. quantitative). To verify the new taxonomy, forensic data which were generated to investigate the culprit of network security was used. The result showed that the new taxonomy was found to be very efficient and effective to choose the right visualized shape for forensic data for network security. In conclusion, the new taxonomy was proven to be very helpful to choose the right information visualization technique by data characteristics.

  • Inappropriate communications can cause a lack of necessary information exchange between operators and lead to serious consequences in large process systems such as nuclear power plants (NPPs). In this regard, various kinds of taxonomies of inappropriate communications have been developed to prevent inappropriate communications. However, there seems to be difficult to identify inappropriate communications from verbal protocol data between operators. Because the existing taxonomies were developed for use in report analysis, there is a problem of 'uncertainty'. In consequence, this paper proposes a new taxonomy of inappropriate communications and provides some insights to prevent inappropriate communications. In order to develop the taxonomy, existing taxonomies for four industries from 1980 to 2010 were collected and a new taxonomy is developed based on the simplified one-way communication model. In addition, the ratio of inappropriate communications from 8 samples of audio-visual format verbal protocol data recorded during emergency training sessions by operating teams is compared with performance scores calculated based on the task analysis. As a result, inappropriate communications can be easily identified from the verbal protocol data using the suggested taxonomy, and teams with a higher ratio of inappropriate communications tend to have a lower performance score.

  • Instructional objectives clearly show what teachers should teach in the class and how they lead the class, focusing on a certain activity for their students in the class. Clear instructional objectives are a prerequisite for teachers to accomplish effectively their curriculum. The revised Bloom's taxonomy table of educational objectives has been introduced in 50 years since the publication of his original taxonomy table in 1956. Bloom's revised taxonomy table of educational objectives has two-dimensions, the "cognitive process" dimension and the "knowledge" dimension, and it classifies class objectives more elaborately and clearly. This study was designed to classify instructional objectives stated in elementary science guidebooks for teachers into Bloom's revised taxonomy table, and see how the objectives of elementary science classes were categorized by grade level and areas. In addition, this study examined how the objectives of elementary science classes by study area were classified into the new taxonomy table. This study classified 618 elementary science instructional objectives of third- to sixth-grade science guidebooks for teachers into Bloom's revised taxonomy table. The results showed that the objectives of elementary science classes emphasized disproportionately some of the knowledge and cognitive process dimensions. In the area of subjects while the percentages of factual knowledge were very high, those of meta-cognitive knowledge were low.

  • The purpose of this parer is to provide a survey of the state of the art of routing methods in store-and-forward computer networks. The survey is carried out in line with a new taxonomy: heuristic methods, user-optimization methods, and system-optimization methods. This taxonomy on routing algorithms is based on two viewpoints: the level of optimization and the relative difficulty for the implementation in real computer networks. Some actual methods implemented in real computer networks are surveyed as well as the theoretical studies in the literature. This paper concludes with some points in need of further researches.

  • The objectives of the study are to investigate pharmacy remuneration levels stratified by the number of prescriptions dispensing and the type of nearby medical facilities using the Korean National Health Insurance (NHI) database, and to classify community pharmacies based on the characteristics. Claims data of all community pharmacies were extracted from the Korean NHI database from January 1 to June 30, 2010. A total of 14,985 pharmacies were included for the analysis. The remuneration amounts per pharmacist were directly associated with the number of prescription dispensing, and varied by the type of nearby medical facilities where more than 90% of prescriptions dispensed at the pharmacy are issued from. We classified pharmacies to six groups according to the number of prescription dispensing and the type of nearby medical facilities; (1) pharmacies with equal to or less than 200 prescriptions per month per pharmacist, (2) pharmacies near a general hospital, (3) pharmacies near a regular hospital, (4) pharmacies near a clinic, (5) pharmacies near multi clinics, and (6) pharmacies that do not belong to the above types. Compared to pharmacies near a clinic or multi clinics, pharmacies near a general hospital showed a lower number of prescription dispensing per pharmacist, but the income from dispensing fees was higher (p<0.05). The new taxonomy of community pharmacies can be a useful basis for further policy development in pharmacy remuneration system.

  • This study aims to describe the overall aspects of future technologies in Korea based on the new taxonomy of technology foresight ; Theme, Area and Paradigm. This taxonomy is designed to overcome and supplement several studies on technology foresights which are judged not to capture the whole aspects of future technologies. Future technologies in Korea will be influenced by the Information and Communication Technology Paradigm over 20-30 years, and by the Biotechnology Paradigm after that period. Expansion of researches in electronics, information and communication is noticeable features in engineering. The application of biotechnology technique and health/environment technologies are emerging in bioscience area. Also there appear new areas related to the trends of engineering and bioscience in natural science. Current research patterns focusing physics, chemistry and engineering in Korea should be changed to those of the advanced countries which emphasize bioscience. Time lag to the world frontier is over 5-6 years, but the lag is expected to be reduced. The shortage of manpower and research funds are pointed as the biggest barrier for the realization of future technologies.

  • The goal of this study is to analyze accidents occurred at experimental laboratory and to suggest hierarchical taxonomy applicable to prepare countermeasures reducing the experimental laboratory accidents. Recent 5 years accidents were analyzed and classified according to their primary cause, facility or human. Then in case of facility, the accidents were further classified whether they can be fixed by organization or by individual. In case of human factor, they were classified into physical, chemical, or biological to prepare precise measures. Depending on the adequacy of appropriate practice, several measures were suggested such as; whether to improve training of laboratory workers, or to improve training the system, or to improve or prepare practice substantially. A new taxonomy for laboratory accident was suggested complying other governmental agencies' classification such as KOSHA and KGS. Additionally, two kinds of possibilities were suggested such as possibility of major accident and possibility of disaster which can be defined as laboratory accident causing large scale of harmful consequence to residential area or environment by fire, explosion and/or toxic release of hazardous chemicals and/or microbiology.

  • Regarding to the huge number of connections and the large flow of data on the Internet, Intrusion Detection System (IDS) has a difficulty to detect attacks. Moreover, irrelevant and redundant features influence on the quality of IDS precisely on the detection rate and processing cost. Feature Selection (FS) is the important technique, which gives the issue for enhancing the performance of detection. There are different works have been proposed, but a map for understanding and constructing a state of the FS in IDS is still need more investigation. In this paper, we introduce a survey of feature selection algorithms for intrusion detection system. We describe the well-known approaches that have been proposed in FS for IDS. Furthermore, we provide a classification with a comparative study between different contribution according to their techniques and results. We identify a new taxonomy for future trends and existing challenges.

  • To acquire the hints of the development of children's multiplication strategies, this study tried to find the differences between the students who learned multiplication and the students who didn't. And we also tried to explore their acquired computational resources. As a result, we confirm that there is a certain direction on the development of children's multiplication strategies according to their grades and the level of acquirement of mathematical knowledge. Moreover, we comprehend that commutative law is an important part of the strategies on two-digit multiplication and that acquisition of the computational resources must precede the learning of multiplication strategies. In the end part, this article proposes a new taxonomy of strategies for multiplication. To support our proposal, we integrated the prior researches with our findings.

  • Objective: The aim of this study is to make the taxonomy for classifying diverse touchless gestures and establish the design requirements that should be considered in determining suitable gestures during gesture-based interaction design. Background: Recently, the applicability of touchless gestures is more and more increasing as relevant technologies are being advanced. However, before touchless gestures are widely applied to various devices or systems, the understanding on human gestures' natures and their standardization should be prerequisite. Method: In this study, diverse gesture types in various literatures were collected and, based on those, a new taxonomy for classifying touchless gestures was proposed. And many gesture-based interaction design cases and studies were analyzed. Results: The proposed taxonomy consisted of two dimensions: shape (deictic, manipulative, semantic, or descriptive) and motion(static or dynamic). The case analysis based on the taxonomy showed that manipulative and dynamic gestures were widely applied. Conclusion: Four core requirements for valuable touchless gestures were intuitiveness, learnability, convenience and discriminability. Application: The gesture taxonomy can be applied to produce alternatives of applicable touchless gestures, and four design requirements can be used as the criteria for evaluating the alternatives.
