Visual interfaces of news sites look similar while their HTML have lots of different specifications and qualities. It's getting more and more significant to describe HTML semantically to make every computer able to understand contents to be shared as HTML5 specification refers. In this study, I have analysed HTML codes of 110 korean news sites in comparison to those of 8 global news sites. As results, 68% of news sites are still described in HTML4 specifications and only 10 out of 110 are in HTML5 specification and as high quality and strong semantics as global news sites. The result shows most korean news sites platforms had not been changed since they developed in mid-2000 and it's needed to be upgraded as language translation technologies are making it possible to share korean digital contents with the rest of world.

The purpose of this study is to investigate the various perspectives that children can provide by utilizing specific physical spaces for play, and to study how to effectively apply them to surrounding spaces and environments. AHP was used to analyze the preferred elements for effectively designing a play area. The main keywords were derived through case studies of various domestic and foreign play space designs, and each keyword was grouped and a keyword of a higher concept was derived. The results of the comparison of 14 keywords that were finally drawn using AHP for each element were used to derive the priority for the preferred elements. As a result, preference was derived in the order of "Openness", "Safety", and "Diversity" in the morphological properties of the play space, and "Adventure", "Five senses elements", "Visual elements" and "Interactivity" in the content properties of the play space.

The operating tasks of overhead crane have caused undue stress to the operators from physical, mental, and environmental workload. Existing workload assessment models for musculoskeletal disorders such as OWAS, RULA, and QEC have limited applicability to the crane operating tasks because they focus mainly on physical factors and do not consider the relative importance of each factor. The present study was to develop a workload assessment model customized to overhead crane operation, following a systematic process: (1) analyzing task characteristics, (2) selecting workload factors, (3) developing assessment methods, (4) establishing action levels, and (5) computerizing the assessment model. Based on literature review, worksite survey, and focus group interview, 4 physical factors (awkward posture, static posture, repetitive motion, and excessive force), 6 mental factors (visual demand, auditory demand, task complexity and difficulty, time urgency, work schedule related stress, and safety related stress), and 4 environmental factors (noise, vibration, dust, and temperature) were selected and their rating scales and relative weights were determined. Then, based on the workload assessment results of 8 overhead cranes operated at different workplaces, the action levels of each factor category were established. Finally, the crane operation assessment model was computerized for effective analysis and report preparation. The present approach is applicable to develop a customized workload assessment model for an operating task under consideration.

The operational availability of multispectral high-resolution satellite imagery, opens up new possibilities for updating forest map. Compared with information acquired by traditional methods (Panchromatic Aerial Photo), these data of for a number of advantages. In this study used 1m spatial resolution and 4 multispectral band, which are capability to update forest map of kind of tree. From the result of this study, First, the visual analysis of the colour composites of the multispectral data made it possible to distinguish some species(conifer, broad-leaved, un-stocked, arable land). Second, forest map and orthorectiffd satellite imagery are not match in the boundary of forest, therefore work have some troubles in the modification of forest map. Third, the distinguish from age-class, girth-class and density are much need experience and skillful about sample such as aerial photo.

At present, monitoring programmes for green network have been mainly based on field sampling, which relies on attributes of an area at one point in time, reflecting an emphasis on the small number of in-situ data. One of the major disadvantages of traditional field monitoring is that it is costly, laborious and time consuming due to the large number of samples required. The aim of this research was to evaluate green network based on pixel of Landsat TM satellite image. An empirical study for a case study site was conducted to demonstrate how a standard remote sensing technology can be used to assist in monitoring the green network based on pixel. The pixel-based analysis made it possible to identify area-wide patterns of green network subject to many different type of artificial structures, which cannot be acquired by traditional field sampling. It was demonstrated that the degradation trends of green network could be used effectively as an indicator to restrict further development of the sites since the quantitative data generated from remote sensing can present area-wide visual evidences by permanent record. It is anticipated that this research output could be used as a valuable reference to support more scientific and objective decision-making in monitoring green network.

The purpose of this study is in allowing thinking about the design development process which is more towards the visual and perceptional aspects related to the form structure by more diverse methods by typology of idea generation. To accomplish such goal, researches in the psychology, pedagogy, engineering, and consilient studies as well as related precedent researches and reference data in architecture, promotion, industrial design, and other art fields and fashion designs are collected and analyzed to see the study trend. In addition, in the content analysis method based on such, the idea generation was classified into types in consideration of relevancy, usefulness, and suitability with fashion. First, a concentrated thinking of a limited space is a method of leading an optimal design by focusing on solving the cause of a problem within a space which generates the problem. Second, plan thinking per section of structure decomposition is a method of dismantling the design problems per organization, thinking type, factor, and characteristic into sub-modules to re-interpret and re-organize the problems in various aspects. Third, an associated thinking through interpreting relationships among vocabularies is a method of selecting the marginal languages that allow a person to come up with concrete forms and the key words related to fashion to import the characteristics and attributes of the marginal languages and thematic relationship between the two terms to search the relevancy. Lastly, the free integrated thinking of language extension is a method of groping integration between other fields and fashion by free integration among the extended terms by extending the vocabularies through inferring metaphorical expressions founded upon individual's memories or knowledge concepts regarding theme words that do not allow concrete forms to come up.

The purpose of this study is to analyze the current use of mannequins that are designed to display Hanbok and put forward suggestions for improvement. In order to carry out the study, an analysis on the mannequins that are currently in the market was conducted along with a survey with professionals who are in charge of the display. The significance of the study is that it has gathered the opinions of professionals who are currently participating in the displays of Hanbok to lay the foundation for improvements. As Hanbok is a flat-pattern costume unlike the Western ones, the most prominent way to display is to lay them on the floor or hang them on the wall. Nevertheless, the mannequin displays are needed to show the beauty of Hanbok as the silhouette can only be completed when it is put on a body. A new type of mannequins that can portray the distinctive features of Korean beauty more effectively need to be developed. Although the museum and enterprise slightly differ in their preferences and requirements for the mannequins, both agree on the following criteria; the shape should be adjusted: the protruding breasts of the mannequin are not suitable for Hanbok, the body should be disassembled: all parts of the body should be separable and it should be flexible at the joints so that it can produce various poses, the face should represent the "koreaness" and the material should be soft. Based on these findings, we put forth the suggestion that a more suitable mannequin should be developed to portray the beauty of Hanbok.

Slope is an important mathematical concept that is connected to advanced mathematics as well as a basic concept as an indicator of the steepness of a straight line. The purpose of this study is to see how the concept of slope is presented in mathematics textbooks of middle school. For this study, we analyzed the types of slope concepts in the textbooks. In particular, we analyzed motivation activity, definition, examples of slope in them and used a concept framework of slope by Stump(1999, 2001), Moore-Russo, Connor & Rugg (2011). As a result, it was shown that middle school mathematics textbooks use the types of slope concepts to be biased when explaining the slope or presenting the slope problems. In addition, the real contexts of slope is poorly presented, and the concept types change from visual aspect to analytical aspect in the processes. This study provides suggestions on how to present the slope concepts in mathematics curriculum and middle school textbooks.

Image deblurring by a deconvolution method requires accurate knowledge of the blur kernel. Existing point spread function (PSF) models in the literature corresponding to lens aberrations and defocus are either parameterized and spatially invariant or spatially varying but discretely defined. In this paper, a parameterized model is developed and presented for a PSF which is spatially varying due to lens aberrations and defocus in an imaging system. The model is established from the Seidel third-order aberration coefficient and the Hu moment. A skew normal Gauss model is selected for parameterized PSF geometry structure. The accuracy of the model is demonstrated with simulations and measurements for a defocused infrared camera and a single spherical lens digital camera. Compared with optical software Code V, the visual results of two optical systems validate our analysis and proposed method in size, shape and direction. Quantitative evaluation results reveal the excellent accuracy of the blur kernel model.
