The purpose of this study was to investigate and analyze the correlations between the knowledge of, attitudes toward, and service requirements for dementia among nursing students. A descriptive study design was used. The participants were 584 nursing students attending K university. The collected data were analyzed by descriptive statistics, the t-test, ANOVA, Scheffe test, and Pearson's correlation coefficients using the IBM SPSS 21.0 program. The mean score of dementia knowledge was low($15.86{\pm}4.58$). The area with the highest correct answer rate for dementia knowledge was life impact(64.2%) and the disease progression area(39.6%) was the lowest. The attitude toward dementia ($45.15{\pm}4.59$) and service requirements($89.88{\pm}9.38$) were relatively high. There were positive correlations between dementia knowledge and dementia attitude(r=.11, p=.008) and service requirements(r=.21, p<.001) and between dementia attitude and service requirements(r=.34, p<.001). Therefore, accurate knowledge of dementia was closely related to positive attitudes. In conclusion, this studyis expected to provide the basic data for the development, application and evaluation of dementia education programs for nursing students.

The bidding method of public works is decided based on the experience of the officials in charge and the convenience of the work, but the validity of decision making process for the bidding method has not been verified. Another challenge in the bidding method selection is its objective validation is not easy because the decision making is based on experience, when a new type of project is ordered or a new bidding method is applied In this study, therefore, a decision making model to facilitate the selection of a public construction project delivery method was developed and examined with its applicability. This model was developed using the Analytic Hierarchy Process and was verified through 32 persons who were actually in charge of the works. As a result of applying this model, 5 of the 32 persons showed consistency in using the model. and they expressed positive opinions about the model. The model can provide a guide while recognizing the fact that they cannot depend entirely on the model. Therefore, the model proposed in this study is expected to reduce the work-related burden of the persons who are involved in the related work and help the objective performance of their tasks when a new bidding method or project appears in the future.

Differ from elder generation, active senior possesses the active characteristics of young people. In this research, the active senior users' UX problem was analyzed by Sundar's 'Interface Assessment'. According to Interface Assessment, the user's subjective user experience in GUI interactive can be divided into five elements, which are 'Visible', 'Desired Outcome', 'Immediate Feedback', 'Intuitiveness', 'Perceived Ease of Use'. Based on these five elements, user's behavior and perception experience during interface using were analyzed to classify UX problems. Next, Correlation Analysis was conducted to find out the relationship between the elements of Interface Assessment and user's subjective experience using PSSUQ as comparing data, and SPSS 22 version as statistic software. The result of this research was presented below: First, active senior user's biggest UX problem can be classified with 'Desired Outcome' in App using. Second, the correlation between the two elements, 'Desired Outcome', 'Perceived Ease of Use', and the PSSUQ result was statistically significant, but the correlation between the other three elements, 'Visible', 'Immediate Feedback', 'Intuitiveness', and the PSSUQ result were not statistically significant. According to the result, active senior users do have different characteristics compared with elder generation. The UX problems classified with 'Desired Outcome' and 'Perceived ease of use' apparently affect user's subjective experience, while the problems classified with 'Visible', 'Immediate feedback', 'Intuitiveness' show no evidence in affecting user's subjective experience. This phenomenon could be explained by the cumulative effects of PC or smartphone use. Through the analysis of multiple UX elements in this paper, better App interface could be developed according to active senior's needs.

The purpose of this study is to develop teaching materials for geological fieldwork around the area of Mai Mountain and to analyze the responses of elementary teachers as to the application of fieldwork. The site of geological fieldwork, Mai Mountain area, is located around the Maisan Provincial Park of Jinan-gun, Jeonbuk Province where a large-scale sedimentary succession in the era of Cretaceous is shown. It provides an easy access to distinct outcrops around the provincial park. The sequences reveal different kinds of sedimentary rocks and various sedimentary structures, and provide information of the lacustrine sedimentary environments of the Cretaceous. In addition, metamorphic rocks and structures formed at the margin of the basement and the basinal fault as well as a sedimentary sequence of the Quaternary formed in a modern fluvial stream are observable. A 4-step fieldwork procedure was applied to a group of 13 elementary teachers. Through questionnaire and interview, results showed that (a) the geological fieldwork and materials were effective to positively increase science teaching from the participating teachers, and that (b) there is a great need of the development of various fieldwork sites and teaching materials that promote active fieldwork for students to have their lived experience and knowledge gain. It is suggested that teacher education programs be able to provide active fieldwork for elementary inservice teachers to properly carry out a geological fieldwork for their students.

Because there is no generally accepted definition of a geographic center and no completely satisfactory method to determine one, there may be as many geographic centers of a country as there are many definitions. The geographic center of an area may be defined as the center of gravity on a surface, or that point on which the surface of an area would balance if it were a plane of uniform thickness. This research uses geographic information system (GIS) analysis and there are places where it defines the geographical and the geological centers in the inland of South Korea. To compute the geo-centers in South Korea: 1) firstly, we collected existing reaserch data related to digital map data. 2)Secondly, we analyzed a geological center and data collection examples of Korea and other nations-the Europe and America. 3) Thirdly, we carried out numerous processes to build a geodatabase, short for geograhic database, so that GIS analysis and the constructed geodatabase is covered within the inland in South Korea. Where geodatabase is a kind of spatial database. 4) Fourthly, in order to determine the geographical center, we supposed that the condition of continental surface is the plane of homogeneous or irregular density. 5) Consequently, we chose a few resonable conditions and produced a variety of geographical centers that is geometric and gravitational in South Korea. As a result of the analysis, center points are massed to southern part of Chungbuk province, Korea.

This paper presents an intuitive 3D modeling interlace based on a field study and prototype development. The process and tools of modeling were observed in workshops of professional design model making, day modeling, wood caning and glass crafting. The Spray Modeling interlace was developed from the observational analysis of the field study. It is a 3D modeling interface which combines particle spraying and day modeling in Virtual or Augmented Reality space. Virtual volume particles are sprayed on frames in Augmented Reality space as day modeling. It adopts a real air spay gun as a tangible interface device which provides coherent sound and air-force feedback. The prototype development and a user study showed that the interface supports new patterns of form development and expression. Control interfaces and requirements of auxiliary devices were found to be improved. This study examines the potential of the new interlace for designers working in 3D virtual and augmented reality. The new spraying interface is also expected to be used as an alternative interface in 3D computer workspace, games, education software and media art.

The quorum sensing (QS) regulatory network has been the subject of extensive studies during recent years and has also attracted a lot of attention because it both positively and negatively regulates various putative virulence factors, although initially considered to be a specialized system of Vibrio fischeri and related species. In this study, to identify the novel materials which inhibit QS system of microorganisms, extracts of eighteen natural products were tested by bioassay using N-(3-oxohexanoyl)-$_L$-homoserine lactone and N-(3-oxooctanoyl)-$_L$-homoserine lactone synthesized in this experiment and an Agrobacterium tumefaciens NT1 biosensor strain containing a traI::lacZ fusion. The result indicated that the extracts of cabbage, leek, and onion exhibited the QS inhibition activity. Thus, materials contained in the extracts were isolated via recycling preparative HPLC and were purified via a JAIGEL-LS255 column. The common fraction corresponding to a peak of the 83 min point of them quenched the quorum sensing of A. tumefaciens NT1 biosensor strain in ABMM containing X-gal and was designated quorum sensing inhibitor-83 min (QSI-83). The QSI-83 exhibited the heat stability and did not inhibit the growth of A. tumefaciens NTl. Furthermore, thin layer chromatography (TLC) results suggested that these novel materials may be antagonists of N-acyl homoserine lactone or may inhibit the QS autoinducer synthesis by Pseudomonas syringae pv. tabaci.

This study observes reporters' awareness on the use of social media and their Core Values by using the Theory of Means-End Chain and drawing conclusions from a Hierarchical Value Map (HVM). In order to analyze reporters' knowledge and awareness on the use of social media via the laddering method, in-depth interviews of 46 reporters were conducted. The study showed that reporters consider sense of kinship, well-balanced understanding, and the desire for knowledge to be important Core Values. The results revealed that the convenience in interpersonal communication, development of intimacy in relationships, entertainment and affection, curiosity, the reduction in the cost of the acquisition of information, understanding of trends in issues, a peek into new information and the maintenance of interests, psychological dependability, and quick updates on information items are considered important Consequences of social media. In the Attributes level, the ability to write postings and links on Facebook and readability and 'follow' and 'mention' features on Twitter were confirmed to be important items in social media. The findings infer that reporters that make use of social media use Twitter and Facebook to build a sense of kinship with other users and gain well-balanced understanding by accessing a lot of information through social media. While this study examined the level of reporters' familiarity with the use of social media via the laddering method, the results cannot be seen as a generalization, as the interviewees were reporters from only the major news organizations.

The main purpose of this study is to examine the implications of Habermas's Critical Theory, which has been considered as modern descendant of enlightenment thought, on the social work profession. The focus of this paper is a critical examination on expected perceptual and practical gain provided by communicative theory for the professional relations between social workers and clients. This paper proves that Habermas's theory has failed to sufficiently grasp the scope and functions of social work practice. First, in regard to perceptual gains, Habermas's theory commits some kind of reductionism which considers communicative behaviors as only and original one. It is likely to limit the scope and extent of the function and mission of social work into a kind of communication performed by humans with communicative ability. Second, in regard of practical gains, Habermas's theory does not provide detail procedure of power-free communication nor critical criteria to evaluate the degree of ideal speech situation. Without these ones, Habermas's critical theory might play a role of liberal conservatism, which is trying to replace the substantial contents with procedural formality. In sum, to be a adequate theoretical and practical framework for social work, Habermas's theory needs to combine additional humanitarian considerations into communicative paradigm with more detail requirements and preconditions for ideal speech situations between professional and clients.
