  • This study aims at evaluating geomorphological classification systems to predict the occurrence of landslides in mountainous region in Korea. Geomorphological classification systems used in this study are Catena, TPI, and Geomorphons. Study sites are Gapyeong-gun, Hoengseong-gun, Gimcheon-si, Yeoju-si/Yicheon-si in which landslide occurrence data were collected by local governments from 2001-2014. Catena method has objective classification standard to compare among regions objectively and understand the result intuitively. However, its procedure is complicated and hard to be automated for the general public to use it. Both TPI and Geomorphons have simple procedure and GIS-extension, therefore it has high accessibility. However, the results of both systems are highly dependent on the scale, and have low relevance to geomorphological formation process because focusing on shape of terrain. Three systems have low compatibility, therefore unified concept are required for broad use of landform classification. To assess the effectiveness of prediction on landslide by each geomorphological classification system, 50% of geomorphological classes with higher landslide occurrence are selected and the total landslide occurrence in selected classes are calculated and defined as 'predictive ability'. The ratio of terrain categorized by 'predictive ability' to whole region is defined as 'vulnerable area ratio'. An indicator to compare three systems which is predictive ability divided by vulnerable area ratio was developed to make a comprehensive judgment. As a result, Catena ranked the highest in suitability.

  • According to the cognitive conflict process model, student anxiety factor is known to have both positive and negative effects on student response behaviors in a conflict situation for conceptual change learning. However, there is little research that reveals what type of anxiety, either constructive or destructive, is related when conducting step-by-step experiments to resolve cognitive conflicts. This study attempted to learn the characteristic of explanatory hypothesis according to anxiety type after conducting five step-by-step experiments related to action and reaction concept. Results found that students who belonged to the types of 'conviction in logical misconception', 'insisting on additional variables', and 'reasonable modification' suggested explanatory hypothesis close to physical nature. On the other hand, those who showed the other five types of anxiety ('compatible predictions', 'dependence on others', 'fusion of past experience', 'lack of confidence', and 'conflict with past experience') suggested temporary supported hypothesis or simple explanatory hypothesis according to student intuition and simple observation. These results indicate that students in the above-mentioned five categories need more external interactions with instructors based on the type of anxiety related to student behavior. In addition, the results present student characteristics which instructors should be more attentive to when using step-by-step experiments to resolve cognitive conflicts.

  • Objectives: The purpose of this study is to examine the modern history of public health(PH) and suggest a way forward for PH nursing(PHN). Methods: This paper is a review article that derives results from literature review. Results: In the period of beginning (up to 1944), PHN began as the PH Department was created in the Hygiene Bureau in 1908 and tasks about nurses were legislated. PHN was limited to infectious disease tasks and performed mostly by missionaries. In the period of foundation formation (1945 to 1961), the Republic of Korea was founded, and PH policies and tasks were defined with the establishment of the central government organization and the applicable laws. In the period of foundation establishment (1962 to 1979), the Regional PH Act was amended, and as a result, PH Centers(PHCs) spread across the country. In the period of foundation expansion (1980 to 1994), the PH referral system of PHCs, PH Units, and Primary Health Care Post was established. In the period of organization in each area (1995 to 2005), PH programs reflecting changes in disease structure and public needs for the quality of life. A regional health care plan was launched. In the period of funtion expansion (2006 to present day), Centers for support health living were established. Conclusions: In the future, PH nurses need to have a macroscopic perspective that views PH through the overall PH system, and to expand from the existing healthcare concept to the national and global healthcare one.

  • In this study, we tried to find the effects of carrying out infographics instruction based on visual thinking with the infographics materials presented in physics textbooks targeting specialized vocational high school students. Thus, 60 students were divided into the experimental group and the control group, the experimental group had 25 classes composed of 'infographics concept formation, infographics understanding activity, and infographics configuration activity', on the other hand, the control group were instructed by lecture-type class. The results of this study are as follows: First, features of the infographics created by the students include changes in types of presentation from 'simple arrangement' to 'simple reconfiguration' and from 'illustration' to 'comparative analysis', which were made by the visual thinking of the students activated in accordance with the increase of their configuration times. Second, instruction by using infographics, visual thinking significantly improved in the level of understanding, visibility, usability, and communicability. Third, after instruction using infographics, the mean score of the experimental group's achievement significantly improved. Fourth, there was a significant improvement in the area of 'normality of scientist, attitude on scientific inquiry, and scientific attitude' in the test of attitudes toward science. From the analysis results, we could conclude that instruction using infographics enhance students' understanding of scientific concepts and communication capability by improving visual thinking abilities, which have a positive impact on academic achievement and attitudes toward science.

  • In this study, we introduce a concept of advanced neurofuzzy polynomial networks(ANFPN), a hybrid modeling architecture combining neurofuzzy networks(NFN) and polynomial neural networks(PNN). These networks are highly nonlinear rule-based models. The development of the ANFPN dwells on the technologies of Computational Intelligence(Cl), namely fuzzy sets, neural networks and genetic algorithms. NFN contributes to the formation of the premise part of the rule-based structure of the ANFPN. The consequence part of the ANFPN is designed using PNN. At the premise part of the ANFPN, NFN uses both the simplified fuzzy inference and error back-propagation learning rule. The parameters of the membership functions, learning rates and momentum coefficients are adjusted with the use of genetic optimization. As the consequence structure of ANFPN, PNN is a flexible network architecture whose structure(topology) is developed through learning. In particular, the number of layers and nodes of the PNN are not fixed in advance but is generated in a dynamic way. In this study, we introduce two kinds of ANFPN architectures, namely the basic and the modified one. Here the basic and the modified architecture depend on the number of input variables and the order of polynomial in each layer of PNN structure. Owing to the specific features of two combined architectures, it is possible to consider the nonlinear characteristics of process system and to obtain the better output performance with superb predictive ability. The availability and feasibility of the ANFPN are discussed and illustrated with the aid of two representative numerical examples. The results show that the proposed ANFPN can produce the model with higher accuracy and predictive ability than any other method presented previously.

  • On the subjects of elementary 3rd grade three child prodigies who had learned the four fundamental arithmetic operations and primary concepts of fraction, this study conducted a qualitative case research to examine how they composed schema of addition and multiplication of fractions and transformed schema through recognition of precise concepts and linking of concepts with addition and multiplication of fractions as the contents. That is to say, this study investigates what schema and transformed schema child prodigies form through composition of primary mathematic concepts to succeed in relational understanding of addition and multiplication of fractions, how they use their own formed schema and transformed schema for themselves to approach solutions to problems with addition and multiplication of fractions, and how the subjects' concept formation and schema in their problem solving competence proceed to carry out transformations. As a result, we can tell that precise recognition of primary concepts, schema, and transformed schema work as crucial factors when addition of fractions is associated with multiplication of fractions, and then that the schema and transformed schema that result from the connection among primary mathematic concepts and the precise recognition of the primary concepts play more important roles than any other factors in creative problem solving with respect to addition and multiplication of fractions.

  • 1. Purpose Lee Je-Ma had continued to revise "Donguisusebowon" by adding the contents of the Symptomatic-pharmacology(病證藥理論) on Soeumin, Soyangin and Taeeumin to it from the first establishment of the old version in 1894 to 1900.(new version). This paper tries to find out the contents and meaning of the Discourse on the Constitutional Symptoms and Diseases(病證論) between the old version and new version and what the Discourse on the Constitutional Symptoms and Diseases affected the Theory of Eight Constitution created in subsequent years. 2. Methods I classified the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" into old version and new version and tried to find out the Theory of Eight morbidities(8病證論) which is the predecessor of the Theory of Eight Constitution, before reviewing their relation. 3. Conclusions 1) The Discourse on the Constitutional Symptoms and Diseases in the old version specify that the externally sensed diseases are caused by the deep sediment of nature(性) and that the internally touched diseases are caused by the violent activities of emotion(情). In addition, it said that all diseases are caused by the specific characteristics of patient's smaller internal organs(偏小之臟). But in new version, the diseases were understood through the concept Exterior, Interior, Heat and cold(表裏寒熱). The new version said that the diseases may be caused not only the specific characteristics of patient's smaller organs but also by bigger organs(偏大之臟). 2) The Theory of Eight Constitution was derived from the Theory of Eight morbidities, in which all kinds of human diseases are caused by 8 disease-orgin organ and that the diseases therefore can be classified into 8 morbidities. The Theory of Eight morbidities reorganized the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" by classifying them into first morbidity and second morbidity. 3) The Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" has decisively affected the creation of the Theory of Eight morbidities which is the predecessor of the Theory of Eight Constitution. The Theory of Eight morbidities may be deemed another interpretation of the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon". As the Theory of Eight morbidities put emphasis on the genetic characteristics, the Theory of Eight Constitution stating that Eight morbidities are caused by different specific constitution was derived.

  • Generally, application of steel pipe pile as deep foundation member needs special requirement for the connection method between steel pipe pile and concrete footing. Even though two types of connection method are suggested in the related specification, type B-method is provident. To investigate real structural behavior of type B connection, several load tests are done with carefully designed experimental system. The purpose of this experiment is mainly focused on the understanding of actual behavior which can be predicted by design theory. At this research stage, vertical and lateral loading test are done for three types of specimen to review stress concentration, formation and behavior of imaginary RC column in the footing and effect of non-slip device installed in the steel pipe pile. The load resistance mechanism in these specific connection method is predicted based on both experimental results. The three-dimensional finite element modeling is also done for the purpose of comparison between numerical and experimental result. With all the results gained from experiment the structural behavior of imaginary RC column in the design concept is confirmed. The role of non-slip device is very important and it affects the resistance capacity with help of composite action of concrete and steel pipe pile.

  • The purpose of this study is focused to the historic changes of Yungnam-Ru(嶺南樓), which are based on the site layout, and architectural forms in architectural building history and historic periods analyzed with the historic reference, paintings, and photos. This study is to search the alteration of the types of axis and the formation of spaces in Yungnam-Ru which is the Ru-Gak(樓閣) The conclusion of the architectural changes from the historic period and architectural form which is the belows. The first Yungnam-Ru by name had been used to be called, before it was re-called Yungnam-Ru by Kim Ju in 1365. Therefore, the hypothesis in naming Yungnam-Ru form assumption that the building under the name of Yungnam-Ru was re-named by Kim Ju from the Old Budist Temple called Yungnam-Sa, should re-considered in history. The second, it is considered that Milyang-Sibyi-Kyungdo(密陽十二景圖) as the painting can only be seen the site layout in 1542. It could be compared the differences of the site layouts from in 1542 to the present time. At that time Nyungpadang(凌派堂) was connected the main buildings called Yungnam-Ru Chimrudang(沈流堂),building was seperated with the Yungnam-Ru at that period. In 1542, the main Building(Yungnam-Ru) was consist of 5 spans of columns(from the front) and 2 spans of columns(from the side). Now, the main Building(Yungnam-Ru) has the 5 spans of columns from the front, and two spans of columns short from the side, compared to the present facade. At the past, Chimrudang(building) has the two spans of columns and one span of columns short, compared to the present facade. The third, It supposed that main building, Nyungpadang and Chimrudang in the composite of facade was connected with Wolrang(月廊) and Hunrang(軒廊) after invatioin from japan in 1592. 1844, (Chosun dynasty, Hunjong 10) the Yungnam-Ru was re-builted by maintaining the same concept in site layout of the past, and finally the three buildings was put together with Wolrang and Hunrang. As a result, the plan of the Yungnam-Ru was expanded with many aspects. From 1542 to 1844, the present site-layout gradually completed with three buildings which was spatially connected. The forth, in the middle age of Chosun dynasty, after added Gaeksa(客舍), the building is for the government officer staying temporally from outside province) in the site, the site layout was greatly changed with volume of building. In 1844, the Yungnam-Ru as the Nugak belongs to Miljukwan(密州館) was expanded spacially and formally. After that time, the burned buildings could not have been re-built because of aspects in government ability and economical ability.
