  • Elementary students' behaviors classifying leaves have been analyzed according to the material types provided for the classification class. 199 sixth grade students were participated in the task classifying the leaves of various plants for the research. The three types of materials provided to them for the class were real leaves, photos of the leaves and explanation cards including the photos of leaves. One of the research findings was that the only material made students handle in the observed behaviors was the real leave of the material types given as classifying. Three were differences between groups in the time required and the number of using criteria for the class. The numbers of criteria had been applied to analyzing their behaviors as classifying the real leaves which were less than those with photo materials. The amount of taken time to classify the real leaves and photo materials were less than those of another material. Finally, the contents of criteria did not differ between groups except appearing properties presented to the task with photo and explanation materials. It is expected that the research can be contributed for elementary school teachers and for curriculum developers to choose appropriate instructional materials as constructing curriculum contents for elementary science to make elementary school students acquire classifying skill in science classes.

  • This study is the primary study for analyzing the classifying characteristics of river wetlands in Korea and China. It is the first step for constructing the wetlands inventories and establishing the wetland conservation strategies in North-Eastern Asia. The case study sites are Han-river which is the representative river of Korea and Tu-men river which is flowing on the borderline of 3 nations, China, North Korea and Russia. The results are as follows : 1. The types of wetlands of Han-river in Korea and Tumen-river in China were classified by the methods of Koo(2002) which is focused on the topography and hydrology and Zhu(2002) which is emphasized the vegetation and habitats. 2. There are three features which are hydrology, topography and soil cover, and vegetation to classify the wetlands into each types. 3. According to the two wetland types by Koo and Zhu, classification system, wetlands in the case study area(Han river and Duman river) were classified by types. 4. In Koo's classifying system(2002), lots of Riverine, Lacustrins and Flat wetlands are found because the topographical and hydrological features are emphasized. On the contrary in Zhu's system(2002), there are lots of Palustrine wetlands because of emphasizing the vegetation. 5. By the topographic and geological characteristics of each sites, there are more wetland types in the lower Tumen river.

  • In Sasang constitutional medicine, the classification of Sasang constitutional types (Tae-Yang, Tae-Eum, So-Yang, and So-Eum) is important for the treatment. There are some problems with the methods used for classifying Sasang constitutional types; old methods such as pulse-palpation are not considered objective and recent methods such as immunohematology are considered expensive, painful and time-consuming. To overcome these problems, a body measurement and finger prints analysis were performed. The purpose of this study was to determine whether the palm prints and the palm creases could be helpful in classifying Sasang constitutional types. Thus, we looked for characteristics of the palm prints and the palm creases according to Sasang constitutional types. Before analyzing the palm prints and palm creases, 760 Korean (465 males, 295 females) were surveyed using two kinds of questionnaires for classifying Sasang constitutional types. As there were no Tae-Yang individuals, we were only able to identify the characteristics of the palm prints and the palm creases for Tae-Eum (288 persons), So-Yang (193 persons), and So-Eum (279 persons) individuals. In this study, the terminal points of D, closed crease, and open crease seemed to be helpful in classifying Tae-Eum and So-Eum individuals. Terminal point 11 and closed crease were frequent in Tae-Eum individuals; whereas, terminal point 7 and open crease were frequent in So-Eum individuals. Therefore, the palm prints and the palm creases seem to contribute to the classification of Sasang constitutional types.

  • The methodology classifying structural types of concrete buildings in the existing seismic fragility functions is too simple to estimate the fragility of existing residential buildings and neighborhood living facilities, especially those below five stories. Their structural types are dependent on information contained in the building register such as main use, total floor area, story, permission date, and first story floor area of the individual building. All of this information is not considered for classifying types in the existing functions; therefore, the goal of this study was to suggest a methodology that classifies structural types of concrete buildings by utilizing such information. The results of this study showed that the suggested methodology can classify structural types better than the existing methodology. Nevertheless, there is still a need to simplify the methodology because fragility estimation demands quickness rather than accuracy.

  • The purpose of the present study was to identify variables for predicting types of outsiders and possible mitigating factors in bullying situations. Participants were 344 $5^{th}$, $6^{th}$ and $7^{th}$ grade students(159 boys and 185 girls). Involvement of outsiders in bullying was examined by proportion. Major findings were that; (1) Over half of the sample(65.4%) were involved in bullying by either actively reinforcing(bully-followers; 6.4%) or passively observing(bystanders; 59.0%); 34.6% were defenders of victims. (2) Multiple discriminant analysis yielded a function of 3 variables(empathy, risk burden, and prosocial moral reasoning) that was effective in classifying bully-followers, bystanders, and victim-defenders. Empathy and prosocial moral reasoning predicted victim-defenders and risk burden predicted bully-followers and bystanders.

  • A wetland is an ecosystem which is the most useful and highly-energetic transition area. This study has been carried out to classify and identify the various types of wetlands in Korea. The main objective of this study are 1) defining and classifying of wetlands, and 2) identifying the wetlands characteristics, and 3) studying cases on the natural wetlands such as Han river, DMZ(Demillitarized Zone), Upo wetland and Yong(Dragon) wetland. The results as follows: 1) Development of the indices for identifying and classifying wetlands in encompassing in such as Ramsar Conference, US NWI(National Wetlands Inventory), Hydrogeomorphic system. 2) Development on the classifying method on the wetlands in the level of supersystem, system, subsystem, class and subclass. The systems include Palustrine and Riverine, and the subsystems are Seasonal, Permanent(Palustrine) and Impersistent, Lower perennial, Impersistent (Riverine). 3) Finally, we find out Young wetland is Palustrine/Permanent/Slope/Persistent, and Upo wetland consists of various types of wetlands, those are, Palustrine/Permanent/Depression/Forest Deciduous, Palustrine/Permanent/Depression/Shrub Deciduous, Palustrine/Permanent/Depression/Persistent, Palustrine /Permanent/Depression/Hydrophytes, and Lacustrine/Permanent/Openwater/Hydrophytes. The taxonomy of this study stems from identifying and classifying wetlands with indices mainly based on hydrologic features and substrates. So, it is needed that consequent studies are to be performed with various viewpoints. And the studying cases were limited because of the restricted entrance into the DMZ, And, we selected only 10 crucial sites in Han river as the subject for wetlands regulation and creation. And, for advanced studies, drawing up inventory and mapping are necessary.

  • The purpose of this study was to analyze scientific thinking types and processes generated in inductive inquiry by college students. Subjects were three college student. Three inductive tasks were developed: Caminalcules set I which is a task consisted of 6 imaginary animals, a potato task which is a task about the interaction between juiced potato and $H_2O_2$, and Caminalcules set 2. Subjects' thinking types and processes were investigated through thinking-aloud method and interview. Subjects' performances were recorded on videotapes and analyzed. Subjects have shown 5 types of inductive thinking in the first task; observing, discovering commonness, discovering pattern, classifying, discovering hierarchy. The processes of inductive thinking shown by students are followed; observing $\rightarrow$discovering commonness $\rightarrow$classifying $\rightarrow$discovering pattern $\rightarrow$discovering hierachy. The subtypes of inductive thinking on observing were investigated by the analysis of subjects' performance on the second task. In analysis of protocol, student' thinking types on observing have been classified as simple observing and operational observing. Operational observing has been categorized conjectural observing and predictive observing. The subtypes of inductive thinking on classification and hierarchy were investigated by the analysis of subjects' performance on the third task. In analysis of protocol, students' thinking types on classification have been searching criteria for classifying and selecting criteria for classifying. Subtypes of discovering hierarchy have been classifying groups and hierarchical ordering by students. Processes of classifying groups proceeded from searching criteria for classifying to selecting criteria for classifying.

  • This study was designed to make a proposal of a classifying model of Korean fashion brands as the first step in a long-term research plan developing a globalization roadmap for Korean fashion industry. On the basis of ownership advantages of a brand which included firm level attributes and brand level characteristics, fashion brands were classified into eight types. The proposed model was expected to provide an efficient and meaningful framework in developing global strategies both for academic and practical purposes. The model proposed four major categories of fashion brands including manufacturer brands, designer brands, retailer brands, and non-brands. Manufacturer brands were further classified into three groups of conglomerate fashion brands, fashion brands, and sports-specialized brands. Non-brands included small/very small-sized manufacturer non-brands, small/very small-sized non-brands, and OEM/ODM exporters. The classifying dimensions, brand type characteristics, and the globalization approach were discussed. Methods to test the reliability and validity of classifying were also discussed in the text.

  • We introduce an implementation of plug-ins on PLUTO. These plug-ins discriminate inflammatory nodules from other types of nodules in chest X-ray CT images. The PLUTO is a common platform for computer-aided diagnosis systems on Microsoft Windows series and it is easy to add new functions as plug-ins. We coded two plug-ins. One of the them calculates features based on medical knowledge. The other plug-in calculates parameters to classify the type of nodules, and it also classifies nodules into inflammatory nodules and others using SVM. These plug-ins are coded using MIST library which is produced at Nagoya University, Japan. In our previous study, the MIST library was parallelized, so that we can utilize a number of CPUs to calculate features and SVM learning/classifying depending on the amount of computation. Using these plug-ins, it became easy to extract features to discriminate inflammatory nodules from other types of nodules and to change parameters for feature extraction and SVM learning/classifying with GUI interface. The accuracy of the classifying result is 100% with 78 solid nodules which contains 43 inflammatory nodules and 35 other type of nodules.
