Objective: To survey knowledge about the factors that influence fertility in a reproductive-age population living in an urban area. Methods: A cross-sectional study was conducted using a questionnaire-based survey among both males and females aged 18-45 years living in the Bangkok metropolitan area. Results: The mean age of the participants was $26.8{\pm}7.2years$ (male, 41.9%; female, 58.1%). Of the participants, 53.1% had an undergraduate degree and 57.1% were single. Only one-fifth of the participants correctly identified the age when fecundity declines in male and female, the definition of infertility, and the period during the menstrual cycle with the highest chance of pregnancy. Approximately three-fourths of the participants correctly identified that cigarette smoking, alcohol consumption, and sexually transmitted infections affect fertility. Conclusion: A considerable knowledge gap about the factors that influence fertility was identified in reproductive-age individuals in an urban area of Thailand. This issue should be urgently addressed by promoting fertility awareness through education, discussions about social perceptions regarding fertility, and reliable sources of knowledge.

Professionalization of Korean interior design is not completed, considering the fact that accreditation and registration systems cannot be found in it. This study, initiated with this concern, analyzed the knowledge area of interior design and architecture in the United States while utilizing accreditation standards of CIDA and NAAB. The purpose of this study is to provide reference to consult for the professionalization of Korean interior design by showing the effects of standardized professional knowledge on professionalization. The utilized research method is a multiple case study, analyzing cases of interior design and architecture in the United States. The unit of analysis is accrediting criteria, including present and revised versions. Content analysis was conducted to interpretate qualitative data collected. The research results include that knowledge differences between interior design and architecture are not clear. This study concludes that standardized professional knowledge emphasizes the technicality elements of knowledge to protect the health, safety and welfare of the public instead of indeterminacy elements. The research results imply that knowledge standardization concerning HSW can be a critical step to professionalization because it can show a jurisdictional boundary as a unique profession.

Objectives: The purpose of this study was to assess general population' AIDS knowledge and attitudes towards AIDS. Methods: Using a multistage area sampling and random digit dialing method, a random sample of individuals aged 19-59 years, living in 16 different area in Korea during September 2007 were interviewed by telephone. Results: In all, 1,087 respondents completed the survey. In most items, respondents displayed a fairly good degree of knowledge about AIDS. However it was lower than that in developed countries. Respondents' attitudes towards AIDS were found to be negative. The knowledge and attitudes towards AIDS were more positive for respondents who were young, educated, office worker or students, higher in income. The higher level of knowledge, the more positive attitudes towards AIDS. Conclusions: In general AIDS related knowledge was relatively low and people showed negative attitudes towards AIDS. Incorrect knowledge and lack of information on AIDS would lead to unnecessary negative attitudes and there need to be addressed by health education programs and campaigns using mass media.

This study was conducted to investigate the nutritional knowledge and eating behavior of elementary school senior students in Incheon area and to develope education program appropriate for them. Questionnaire was developed and distributed to 551 fifth and sixth grade students of fourteen elementary schools in Incheon area. The data was analyzed using ANOVA. According to the results on nutritional knowledge and attitude, senior students were aware of major sources of some nutrients, but didn't seemed to know about the role of some nutrients. Nevertheless, it was favorable that they took various food from major food groups. But the proportion of students skipping breakfast and taking instant food was high. Their table etiquette was not good at home, but attitude for food hygiene was comparatively good. They recognized Korean traditional food more nutritious than fast food. Even though they understood what was right for eating behavior, they didn't practice it correctly. From these results, it seemed that follow-up study or intervention is necessary to improve nutritional knowledge and eating behavior of the students. Qualified teachers, nutrition specialists, are required in order to develop and apply systematic nutrition education program for correcting inappropriate eating behavior of the students. Furthermore, nutrition education for their parents will be more effective.

For the reliable prediction of spatial geotechnical data, a procedure to build the Geotechnical Information System (GTIS) based on geo-knowledge within the frame of GIS technology was developed by introducing a couple of new concepts of the extended area containing the study area and the additional site visit for acquiring surface geological data. To build the GTIS for Gyeongju as the case study of regional model application, intensive site investigations and pre-existing geotechnical data collections were performed and additional site visit was also carried out for acquiring surface geo-layer data in accordance with the developed procedure. Within the GTIS based on geo-knowledge for Gyeongiu area, the spatially distributed geo-layers across the extended area were predicted using the geostatistical kriging method and those for the study area were extracted. Furthermore, the spatial distribution maps for the thickess of geo-layers and the depth to bedrock were constructed for the practical use in geotechnical field. It was evaluated that the GTIS based on geo-knowledge developed in this study is superior to the conventional geotechnical GIS in terms of both the standard deviation and the geological expert judgment.

The purpose of this study is to investigate mathematics content knowledge(MCK) of pre-service teachers about the area of a circle. 53 pre-service teachers were asked to perform four tasks based on the central ideas of measurement for the area of a circle. The results of this study are as follows. First, pre-service teachers had some difficulty in describing the meaning of the area of a circle. Quite a few of them didn't recognize the necessity of counting the number of area units. Secondly, pre-service teachers had insufficient content knowledge about the central ideas of measurement for the area of a circle such as partitioning, unit iteration, rearranging, structuring an array and approximation. Lastly, few pre-service teachers understood the concept of actual infinity. Most students regarded the rectangle as the figure having the approximation error instead of the limitation from rearranging the parts of a circle.

The purpose of this study is to develop a composite platform for knowledge extractions, visualizations, and inference. Generally, the big data sets were frequently used in the healthcare and medical area. To help the knowledge managers/users working in the field, this study is focused on knowledge management (KM) based on Data Mining (DM), Knowledge Distribution Map (KDM), Decision Tree (DT), RDBMS, and SQL-inference. The proposed mechanism is composed of five key processes. Firstly, in Knowledge Parsing, it extracts logical rules from a big data set by using DM technology. Then it transforms the rules into RDB tables. Secondly, through Knowledge Maintenance, it refines and manages the knowledge to be ready for the computing of knowledge distributions. Thirdly, in Knowledge Distribution process, we can see the knowledge distributions by using the DT mechanism.Fourthly, in Knowledge Hierarchy, the platform shows the hierarchy of the knowledge. Finally, in Inference, it deduce the conclusions by using the given facts and data.This approach presents the advantages of diversity in knowledge representations and inference to improve the quality of computer-based medical diagnosis.

The purpose of this article is to develop a dynamic model of organizational capabilities and knowledge creation, and at the same time identify the organizational capability factors for effective knowledge creation, by empirically analyzing the history of new Quinolone antibacterial drug compound (LB20304a) discovery process at LG, as a case in point. Major findings of this study are as follows. First, in a science-based area such as drug development, the core of successful knowledge creation lies in creative combination of different bodies of scientific explicit knowledge. Second, the greater the difficulty of learning external knowledge, the more tacit knowledge is needed for the recipient firm to effectively exploit that knowledge. Third, in science-based sector such as pharmaceutical industry, the key for successful knowledge creation lies in the capability of recruiting and retaining star scientists. Finally, for effective knowledge creation, a firm must keep its balance among three dimensions of organizational capabilities: local, process, architectural capabilities.

The purpose of this study was to analyze teachers' pedagogical content knowledge (PCK) about area of plane figure and how it was actualized in instruction. As an exploratory, qualitative, and comparative case study, 2 fifth-grade teachers were selected. Semi-structured interviews with the leachers were conducted in order to explore their PCK with regard to the area of plane figure. A total of 14 mathematics instructions were videotaped and transcribed. Teachers' PCK and classroom teaching practices were analyzed in detail into 3 categories: (a) knowledge of mathematics contents, (b) knowledge of students' understanding, and (c) knowledge of instructional methods. As such, this paper provided a detailed description on each teacher's PCK and her teaching practice. The results showed that teachers' PCK had a significant impact on instruction. The teacher who had rich knowledge about the area of plane figure was able to encourage students to understand the concept of area and to or explore the principles behind formula calculating various areas of plane geometry. The results demonstrated the importance of individual components of PCK as well as that of overall level of PCK. Different aspects of teaching practices were observed as to how the teachers had internalized PCK. On the basis of a close relationship between teachers' PCK and their teaching practice, this paper finally raised several implications for teachers' professional development for effective mathematics instruction.
