This paper deals with Kripke-style semantics, which will be called set-theoretic Kripke-style semantics, for weakly associative substructural fuzzy logics. We first recall three weakly associative substructural fuzzy logic systems and then introduce their corresponding Kripke-style semantics. Next, we provide set-theoretic completeness results for them.

This study reports a research which was conducted on how frequently and where the students use the unit circle method while dealing with trigonometric functions in solving the trigonometry questions. Moreover, the reasons behind the choice of the methods, which could be the unit circle method, the ratio method, or the use of trigonometric identities, are also investigated to get an insight about their understanding. In this study, the relationship between the students' choices of methods in solving questions is examined in terms of instrumental or relational understanding. This is a multi-method research which involves a range of research strategies. The research techniques used in this study are test, verbal protocol (think aloud), and interview. The test has been applied to ten tenth grade students of a public school to get students' solution processes on the paper. Later on, verbal protocol has been performed with three students of these ten who were of the upper, middle and lower sets in terms of their performance in the test. The aim was to get much deeper data on the students' thinking and reasoning. Finally, interview questions have been asked both these three students and other three from the initial ten students to question the reasons behind their answers to the trigonometry questions. Findings in general suggest that students voluntarily choose to learn instrumentally whose reasons include teachers' and students' preference for the easier option and the anxiety resulting from the external exam pressure.

Recently, Graph Database (GDB) is being used in wide range of industrial fields. GDB is a database system which adopts graph structure for storing the information. GDB handles the information in the form of a graph which consists of vertices and edges. In contrast to the relational database system which requires pre-defined table schema, GDB doesn't need a pre-defined structure for storing data, allowing a very flexible way of thinking about and using the data. With GDB, we can handle a large volume of heavily interconnected data. A network service provider provides its services based on the heavily interconnected communication network facilities. In many cases, their information is hosted in relational database, where it is not easy to process a query that requires recursive graph traversal operation. In this study, we suggest a way to store an example set of interconnected network facilities in GDB, then show how to graph-query them efficiently.

Among Human Sensibility-oriented products a gap between the images that designers try to express through that product and users emotional evaluation becomes an issue. The data on the correlation between image words used for design evaluation and images used in the design process are especially significant. This study based on these correlations suggests a Fuzzy retrieval system supporting styling design with images and image words. In the system, the relational data are demonstrated by Fuzzy thesaurus as correlation coefficient from the degree of similarity among image words. And the degree of similarity is produced based on image evaluation. Image retrieval is conducted by the algorithm of Fuzzy thesaurus development, 1) among image words, 2) images to image words, 3) image words to images and 4) among images: 4 different modes are provided as retrieval modes. Also transfer between modes is carried by direct operating interface, therefore divergent thinking and convergent thinking is supported well. The system consists of operation for the gap and the measurement unit of emotional evaluation, and visualization units. Under unified interface environments are set in order for consistency of the operation.

Purpose: The purpose of this study is developing the nursing information system which contains the core elements of nursing practice, the Nursing Minimum Data Set (NMDS) that should be collected and documented all the settings in which nursing care is provided. Method: The program was developed under the hospital information system by TCP/IP protocol and used NANDA, Nursing Interventions Classification (NIC), and Nursing Outcomes Classification (NOC) to fill out the elements of NMDS. The Oracle was used as DBMS under the Windows 98 environment and Power Builder 5.0 was used as a program language. Results: This study developed linkage among the NANDA-NOC-NIC to facilitate choosing correct nursing diagnosis, interventions, and outcomes and stimulate nurses' critical thinking. Also the system developed includes nursing care sensitive patient outcomes, so nurses can actively involve in nursing effectiveness research by analyzing the data stored in the database or by making relational databases with other health care related databases. Conclusion: The program developed in this study ultimately can be used for the nursing research, policy development, reimbursement of nursing care, and calculating staffing and nursing skill mix by providing tool to describe and organize nursing practice and measure the nursing care effectiveness.

It is the base of the health through life, the health of children is very important. The health education is the most effective measure for disease prevention and health promotion. To educate children for the health, we must consider their concept of the health before. Therefore I attempted this study for investigation for the concept about respiratory communicable disease which is one of the most important health problems. The design of this study was descriptive investigational study. The subjects of this study are 4-6 aged 65 children who are attending district nursery school. The tools of this study constituted 3 parts as an etiological agents, environmental agents and host agents. The data were collected by an individual interview and cartoon cards. The results of this study are as followed: 1. The preschool children tend to think contamination along the physical distance, nearer things more relational. 2. The preschool children tend to have their experience centered thinking. 3. There was a highly significant correlation between the children's age and knowledge scores(r = 0.431, P= 0.0003). 4. There wasn't a significant correaltion between sex group. In conclusion, it wad founded that the preschool have a tendancy to think communicable disease along the physical distance and their daily life experiences. This results support the Piaget's cognitive developmental theory. Therefore, to develop the health education program for preschool students, above results must be referenced.

Analogy, based on a similarity, is to infer the properties of the similar object from properties of an object. It can be a very useful thinking tool for learning mathematical patterns and laws, noticing on relational properties among various situations. The purpose of this study, when manipulating hint condition, figure and table conditions and the amount of original learning by using algebra word problems, is to verify the effects of analogical transfer in solving equivalent, isomorphic and similar problems according to the similarity of source problems and target ones. Five study questions were set up for the above purpose. It was 354 first grade students of S and G middle schools in Seoul that were experimented for this study. The data was processed by MANOVA analysis of statistical program, SPSS 10.0. The results of this studies would indicate that most of the students would be poor at solving isomorphic and similar problems in the performance of analogical transfer according to the similarity of source and target problems. Hints, figure and table conditions did not facilitate the analogical transfer. Merely, on the condition that amount of teaming was increased, analogical transfer of the students was facilitated. Therefore, it is necessary to have students do much more analogical problem-solving experience to improve their analogical reasoning ability through the instruction program development in the educational fields.

The aim of this study was to provide fundamental information on the validity and credibility of the Korean geometric psychological assessment (GEOPIA) by investigating the degree of relation between the GEOPIA and the MBTI. Data was collected from 331 subjects aged 19 to 70, residing in Seoul, Gyeonggi Province, Jeolla Province, or Gyeongsang Province. Participants completed the GEOPIA and the MBTI during the period of May to September 2017. The study calculated Cronbach's ${\alpha}$ to verify the tests' validity and reliability through SPSS. For the relational analysis between the results of the tests, we conducted a one-way analysis of variance on the first group of the GEOPIA's personality types, and the Scheffe Test if significant relationship was found. The study found that the circle type was predisposed to ESFJ, the triangle type to ESTJ, the rectangle type to ISTJ, and S type to INFP. Higher scores of feeling (F) and perceiving (P) corresponded to circle and S types, thinking (T) and judging (J) for triangle and rectangle types, extroversion (E) for circle and triangle types, and introversion (I) for rectangle and S types. These confirmed the substantial relations between the GEOPIA and the MBTI.

This paper aims to figure out the impact of employee's travel experience on their happiness and motivations to work. To this end, targeting 405 employees in Daegu, Gyeongsangnamdo, and Gyeongsangbukdo, SPSS Statistics 18.0 program was applied to analyze. Frist, in travel experience depending on general characteristics of the targets, there was significant difference in gender, educational background, and occupation but there was significant difference in age, marital status, and average income. Second, there was difference in travel experience depending on frequency of domestic travel but no difference in terms of the period of stay. On the other hands, travel experience depending on frequency of overseas travel showd significant difference in sub-factor, human network experience. There was significant difference in overseas travel depending on period of stay. Third, travel experience showed positive relation in employee's motivation to work and happiness. Fourth, as a result of reviewing impact of travel experience on employee's motivations to work and happiness, sub-factors like emotional, behavioral, relational experiences affected motivations to work significantly. Emotional experience and cognitive experience didn't affect significant impact. And sub-factors of travel experience like emotional, cognitive, and behavioral experiences affected happiness significantly. Emotional and relational experience were not significant. From the research above, it turned out that travel experience gives happiness to employees and provokes positive thinking and their motivations to work.

This paper explored the effect of digital epistemology on Christian education. The media of an era determines the type and form of the epistemology of that era, which in turn has a decisive influence on the direction of Christian education in that era. Therefore, it consists of three parts. First, an investigation on the relationship between media and epistemology, second, an investigation on digital epistemology, and third, an investigation on the effect of digital epistemology on Christian education. In this paper, first, from the perspective of McLuhan's media theory, it was discovered that media go beyond simply expanding the our senses and change our perception through creating a new environment and way of life. This paper could characterize digital epistemology in the following four ways through comparison with the traditional epistemology of the print media era: namely "from linguistic to omnisensory epistemology", "from causality to relational epistemology", "from historical to post-historical thinking", and "from interpretive to performative epistemology". In addition, it examined the effects of that digital epistemology on Christian education. Through this study, it found that digital media can act both positively and negatively on the essence of Christian education. Therefore, the task of Christian education in the digital age is to make it a positive function rather than a dysfunctional one, and an opportunity rather than a challenge.
