This paper explored satisfaction and revisiting of participants on Busan Contents Market(BCM) programme in 2009. Specifically, this study conducted regression analysis for finding satisfaction and revisiting factors on main events, broadcasting-telecom convergence forum, broadcasting business marketing forum, world culture contents forum and BCM academy. Results show as following. Firstly, Participants satisfied on comfortable lodging and possibilities as international events, but not satisfied on facilities, managements, public relations, contents and service. In particular, regional attraction and interpretation service are one of factors for revisiting in BCM main events. Secondly, one of competition factors for revisiting intention in BCM main events is production and investment. Thirdly, contents, theme and qualities of presenters and discussants are main factors for revisiting in BCM. Fourthly, satisfaction degree on education contents and lectures in BCM academy is high and contents, time, line up of lectures analyzed as determined factor for revisiting. Fifthly, documentary planning, production and marketing with international investors drive to induce revisiting BCM. We discussed motivation and utility values for revisiting of broadcasting contents market.

A robust algorithm to disclose and display the difference of ictal and interictal perfusion may facilitate the detection of ictal hyperfusion foci. Diagnostic performance of localizing epileptogenic zones with subtracted SPECT images was compared with the visual diagnosis using ictal and interictal SPECT, MR, or PET. Ietal and interictal Tc-99m-HMPAO cerebral perfusion SPECT images of 48 patients(pts) were processed to get parametric subtracted images. Epileptogenic foci of all pts were diagnosed by seizure free state after resection of epileptogenic zones. In subtraction SPECT, we used normalized difference ratio of pixel counts(ictal-interictal)/interictal ${\times}100%$) after correcting coordinates of ictal and interictal SPECT in semi-automatized 3-dimensional fashion. We found epileptogenic zones in subtraction SPECT and compared the performance with visual diagnosis of ictal and interictal SPECT, MR and PET using post-surgical diagnosis as gold standard. The concordance of subtraction SPECT and ictal-interictal SPECT was moderately good(kappa=0.49). The sensitivity of ictal-interictal SPECT was 73% and that of subtraction SPECT 58%. Positive predictive value of ictal-interictal SPECT was 76% and that of subtraction SPECT was 64%. There was no statistical difference between sensitivity or positive predictive values of subtraction SPECT and ictal-interictal SPECT, MR or PET. Such was also the case when we divided patients into temporal lobe epilepsy and neocortical epilepsy. We conclude that subtraction SPECT we produced had equivalent diagnostic performance compared with ictal-interictal SPECT in localizing epileptogenic zones. Additional value of these subtraction SPECT in clinical interpretation of ictal and interictal SPECT should be further evaluated.

Unlike a study related in language alone, rhetorical study of current time, composed with multi-culture, medias, communication, presents its own field that covers from the form of discourse(persuasive) to another form of discourse(not persuasive). If there was a study of making beautiful sentences for story and finding simple method of speech in Greek and roman period of an ancient time, it now a study in which one finds the essence of literary style or terminology in the expression of sentence. The taller case is especially important, given that the importance of what to express visually is on-going active procedure of this stuffy as itself an activity of communication. When a visual object persuades viewers, the activity of communication derives them to react and to understand the intention of an artist. The matter of how to speak is the matter of how to shape message persuasively. This persuasive method or technique is study of rhetoric. The three aspects (figurative, accentuating, mutating) of rhetorical expression of an illustration, the visual image can give fresh feelings to be in intimate relations with public. These rhetorical expressions also vitalize the story that is expressed on illustration with crisp image. It helps to attain expected effects while discovering essential meaning through the corresponding linguistic interpretation of an image. The study aims at the most effective way to communicate by figuring the most strong and direct illustrative message out. One of the method is to patternize illustrative expressions that are established from all kinds of shapes of Rhetoric. Therefore ,an operation of significance and an implication can shape an ultimate goal of this study from acknowledging the mechanism that modern illustration embraces.

This paper aims to make an aesthetic inquiry into representing modes of wilderness in western films. The western film was the first genre in earnest about natural landscape, covering vast areas of America from the East to the West. It adopted representative modes suited to physical characteristics of landscapes which produced aesthetic characteristics. In western films, wilderness was represented at a distance from the camera lens as a setting and an object of contemplation. In eastern forest landscapes, western films adopted the visual model of Hudson River School's landscape painting which expressed the transcendental sublime. The western semiarid region reproduced the warrior's gaze shot from a high angle, and, in this visual mode, wilderness was expressed as a demonic landscape derived from Burke's definition of the sublime. On one hand, the western desert was represented as a place of hardship shot at a low angle which expressed the vastness, unevenness and limitlessness of the desert owing to the absence of horizon. On the other hand, the mesas of Monument Valley have sublime characteristics of size and time. In western films, they play the role of an emblem by rising from the limitless desert on the horizon. The prospect-refuge relationship, the desire to see without being seen, is discovered in the representative mode of wilderness in western films. In this context, this study hopes to discover the archetype of landscape representation.

The credible measurement, reporting and verification (MRV) is among the most critical elements in UN-REDD (United Nations programme on Reducing Emissions from Deforestation and forest Degradation in Developing Countries). This study is intended to explore MRV potential in terms of UN-REDD opportunity cost estimation using satellite image for Mt. Geum-gang of North Korea. A visual interpretation were conducted to evaluate MRV conditions by sub-dividing or decomposing the images with different pixel size into a three types of hierarchical tree structure that helps dealing with spatial variability within each subarea. The permanent record of standard satellite remote sensing system demonstrated its capability of presenting area-wide visual evidences of MRV conditions in Mt. Geum-gang (such as the identification of forested area, degradation trends for forest space, three types of hierarchical land-cover and land use tree structure, carbon density in the landscape). Satellite data could be accepted as legally binding proof when it comes to REDD opportunity cost estimation since several cases exist where remote sensing has been used as legal evidence in ICJ (International Court of Justice) and UN resolution. It doesn't seem very difficult to comply with MRV requirements for UN-REDD opportunity cost calculation due to the probative value of satellite data. It is anticipated that this research output could be used as a valuable reference for Korea-based enterprises exploring REDD project sites and the carbon traders to ensure MRV potentials using satellite image in UN-REDD Opportunity Cost estimation.

The main objective of this study is the assessment of the ability of limestone mortars to resist to different chemical attacks. The ability of polypropylene (PP) fibres waste used as reinforcement of these concrete materials to enhance their durability is also studied. Crushed sand 0/2 mm which is a fine limestone residue obtained by the crushing of natural rocks in aggregates industry is used for the fabrication of the mortar. The fibres used, which are obtained from the waste of domestic plastic sweeps' fabrication, have a length of 20 mm and a diameter ranging between 0.38 and 0.51 mm. Two weight fibres contents are used, 0.5 and 1%. The durability tests carried out in this investigation included the water absorption by capillarity, the mass variation, the flexural and the compressive strengths of the mortar specimens immersed for 366 days in 5% sodium chloride, 5% magnesium sulphate and 5% sulphuric acid solutions. A mineralogical analysis by X-ray diffraction (XRD) and a visual inspection are used for a better examination of the quality of tested mortars and for better interpretation of their behaviour in different solutions. The results indicate that the reinforcement of limestone mortar by PP fibres waste is an excellent solution to improve its chemical resistance and durability. Moreover, the presence of PP fibres waste does not affect significantly the water absorption by capillarity of mortar nether its mass variation, when exposed to chloride and sulphate solutions. While in sulphuric acid, the mass loss is higher with the presence of PP fibres waste, especially after an exposure of 180 days. The results reveal that these fibres have a considerable effect of the flexural and the compressive behaviour of mortar especially in acid solution, where a reduction of strength loss is observed. The mineralogical analysis confirms the good behaviour of mortar immersed in sulphate and chloride solutions; and shows that more gypsum is formed in mortar exposed to acid environment causing its rapid degradation. The visual observation reveals that only samples exposed to acid attack during 366 days have showed a surface damage extending over a depth of approximately 300 ㎛.

Purpose This study aimed to investigate which indirect parameters on preoperative MRI were the principal predictors of subscapularis tendon tears (STTs) requiring surgical repair. Materials and Methods Preoperative MRI scans of 86 patients were retrospectively reviewed for visual assessment of the STT, pathology of the long head of the biceps tendon (LHBT), posterior decentering (PD) of the humeral head, humeral rotation, fatty degeneration, and subscapularis muscle atrophy. To evaluate atrophy, visual grading using the anatomical line connecting the coracoid tip to the glenoid base, designated as the base-to-tip line (BTL), and thickness measurements were performed in the en-face view. Results Arthroscopically, 31 patients (36%) exhibited Lafosse type III or IV STT and underwent surgical repair. LHBT pathology (p = 0.002), PD of the humeral head (p = 0.012), fatty degeneration (p < 0.001), and BTL grade (p = 0.003) significantly correlated with STT. In the multivariate analysis, PD of the humeral head (p = 0.011, odds ratio [OR] = 5.14) and fatty degeneration (p = 0.046, OR = 2.81) were independent predictors of STT. Conclusion PD of the humeral head and fatty degeneration of the subscapularis can help to diagnose clinically significant STT. Interpretation of these findings may contribute to the planning of an optimal surgical strategy.

In Hwangtohyun, meaning 'red soil pass', reddish surface mantles is widespread. Other granitic hills, exceptionally Naju and Youngam area, in Korean peninsula don't commonly have that color. This paper attempts to address this issue by CIA(chemical index of alteration). CIA data and A-CN-K diagram provide crucial insights into the changes in the relative contributions of chemical physical weathering in difference of grus regolith and saprolite. CaO and $Na_2O$ show strong depletion and $K_2O$ is progressive loss. In grus regolith, weathering trends are (sub)parallel to the CN-A join of the A-CN-K diagram, but the sample's composition plot ever closer to the A-K join in saprolite. The difference of weathering trend obtained using CIA data corresponds closely with the visual interpretation of soil color and texture.
