This study was designed to localize the distribution of basic fibroblast growth factor(bFGF) in the developing rat condylar region and to elucidate the associated function of bFGF in the condyle development. The condyles of temporomandibular joint of Sprague-Dawley rats (27g of weight) were used. The tissues were examined with electron microscope and immunohistochemical method. The results were as follows: 1. The developing condylar region are divided in to 5 zones apparently: proliferative, maturation, hypertrophic, calcifying, and ossification zones. 2. The cells in the proliferative zone are condensed and have under-developed cell organells in the cytoplasm. This zone shows a strong immunoreactivity of bFGF. 3. The cells in the maturation zone are typical chondroblasts showing well-developed cell organells and round nucleus. The cartilaginous matrix does not show the immunoreactivity of bFGF, while the chondroblasts show the immunoreactivity. 4. The cells in the hypertrophic zone show hypertrophic change having the degenerated cell organelles and small nucleus. There are no immunoreactivity of bFGF in this zone except the nucleus and endoplasmic region showing mild immunoreactivity. 5, The cells in the calcifying zone show hypertrophic change and cell organelles are disappeared. The cells are surrounded by the calcified cartilaginous matrix. There are no immunoreactivity of bFGF in this zone except the endoplasmic region showing mild immunoreactivity. 6. In the zone of bone formation, chondroblasts are disappeared. Newly differentiated osteoblasts secreting osteoid around the calcified cartilaginous matrix. The bone marrow shows the immunoreactivity of bFGF, while the bone matrix does not show the immunoreactivity of bFGF.

This study has estimated the traits of conscious eye moving with the objects of the halls of subway stations. For that estimation, the observation data from eye-tracking were matched with the experiment images, while an independent program was produced and utilized for the analysis of the eye moving in the selected sections, which could provide the ground for clarifying the traits of space-users’ eye moving. The outcomes can be defines as the followings. First, The application of the independently produced program provides the method for coding the great amount of observation data, which cut down a lot of analysis time for finding out the traits of conscious eye moving. Accordingly, the inclusion of eye’s intentionality in the method for extracting the characteristics of eye moving enabled the features of entrance and exit of particular objects with the course of observing time to be organized. Second, The examination of eye moving at each area surrounding the object factors showed that [out]→[in], which the line of sight is from the surround area to the objects, characteristically moved from the left-top(Area I) of the selected object to the object while [in]→[out], which is from the inside of the object to the outside, also moved to the left-top (Area I). Overall, there were much eye moving from the tops of right and left (Area I, II) to the object, but the eye moving to the outside was found to move to the left-top (Area I), the right-middle (Area IV) and the right-top (Area II). Third, In order to find if there was any intense eye-moving toward a particular factor, the dominant standards were presented for analysis, which showed that there was much eye-moving from the tops (Area I, II) to the sections of 1 and 2. While the eye-moving of [in] was [Ⅰ→A](23.0%), [Ⅰ→B](16.1%) and [Ⅱ→B](13.8%), that of [out] was [A→Ⅰ](14.8%), [B→Ⅰ](13.6%), [A→Ⅱ](11.4%), [B→Ⅳ](11.4%) and [B→Ⅱ](10.2%). Though the eye-moving toward objects took place in specific directions (areas), that (out) from the objects to the outside was found to be dispersed widely to different areas.

This study was carried out to examine the establishment of the system, which topographical data was used, as a simulation model necessary for discovering the spot with a good view and preparing and the Regulation System for Scenery Protection. The findings found in this research are as follow; 1) The spot with the best view and scenery to be protected has been chosen by analyzing the scenery of each spot within the Buseok-Temple, considering the movement line. It seems that there are not many restful spaces along the traveling route and some elements such as slope-ways and stairs that can obstruct the fine view in the Buseok-Temple. However, this temple contains a great potential to make the view more changeable, variegated, exciting and attractive. 2) In the topographical data used for the analysis of visibility, there is only just ignorable problem when the lattice’s space (interval) is in a short distance. However, in 2~7km distance, the visible rage significantly varies depending on the lattice’s space. It has been found that the most desirable interval of the lattice is Max 20m. 3) A 3D simulation model of the viewed scenery has been prepared as the Regulation System for Scenery Protection in order to analyze the visible rage of scenery. The changes of the scenery extent has been figured out by adding other elements such as trees including the configuration of the ground. Trees usually obstruct the visible range. The higher the trees are, the more the visible range decreases. 4) The visible range at the viewing spot has been analyzed to be protected by discovering the spot with the finest view and by using 3D data. Based on the visible range, the foundational data to be used as the resources for the development of the Regulation System for Scenery Protection have been made/suggested. 5) The natural view can be improved by our efforts while historical view of cultural assets is inherited from our ancestor and it can not be changed. In this study, the methods to control the scenery to be protected and its area have been developed. In the present, other researchers usually focus on the area to be protected for the Scenery Protection of historical resources. However, in this study, a different approaching view of Scenery Protection method is offered by presenting a protection method focused on the view.

This research is about the characteristics of the saccades that occurring in the process of observing the spatial. The size of the saccades is the visual activity for acquiring the information, and the search trace that left by the spatial visitor. Reviewed over the saccade through the analysis of observation process that appeared in the eye-tracking experiment of sports store from the department store, the saccade is defined as the sight movement in the process of finding a component to view in the spatial. If some spatial component induces saccade, and able to know which specific component acquired through the saccade, then the designer will have a clue which able to provide the spatial desired by the consumer. The results of analyzing the process in the deriving the spatial component and saccade characteristic from industrial space, can be summarised as follows. The first, the average fixed number of [IN].[OUT] zone appeared similarly, and it leads to knowing that the time used for attention with one frequency is about 0.3 seconds. Second, there were more saccades toward [IN→OUT] (13 persons, 76.5%) than [OUT→IN] (4 persons, 23.5%). The Los Angeles area has lots of interesting things to watch, so it able to thinks to begins with small saccade and then occur to bigger saccade activity to find new interests shortly after [OUT] saccade. Third, according to time range changes, keep eyes on the characteristics of saccade, [IN].[OUT] frequency has slightly decreased the changes of viewing time, but there was no significant change in an average number of observations. This means that the frequency and the number of observations are decreased together. Therefore, it can be seen that the amount of information to be acquired (frequency) is decreased (count) as the observation time elapses.

공유수면매립면허의 감정평가 기준에 대한 검토 : 새만금개발사업을 중심으로

김종하(Kim, Jong-Ha) 韓國土地公法學會 2015 土地公法硏究 Vol.68 No.-

공유수면매립사업에 대한 일반법은 공유수면법이다. 이에 대해서 특별법 성격인 새만금사업법은 사업의 특성상 공유수면 매립지 공급 및 소유권, 매립면허 양도 · 양수 등에 대하여 특례 규정을 두고 있다. 그러나 양법에서 매립면허 양도 · 양수 시 감정평가에 대해서는 규정하고 있지 않다. 따라서 매립면허에 대한 감정평가를 할 때에는 관련 법령을 종합적으로 판단하여 제반 사항을 고려한 감정평가가 이루어져야 한다. 이에 본 논문에서는 최근 공유수면매립면허 양도 · 양수와 관련하여 감정평가 기준에 대해서 논란이 있었던 새만금개발사업을 중심으로 매립면허 감정평가의 기준을 제시하고자 한다. 이에 본 논문에서는 공유수면매립사업에 대한 일반법인 공유수면법을 검토하고, 이를 토대로 새만금사업의 특성 및 새만금사업법에서 규정하고 있는 특례규정을 검토하였다. 본 논문의 사례로 선정한 새만금사업의 경우에는 원형지 공급이 가능하나, 원형지의 개념에 대해 특정하고 있지 않아 매립면허의 양도 · 양수가 사실상 원형지 공급, 즉 토지의 공급을 내포할 수 있다. 즉 새만금사업의 매립면허 양도 · 양수는 매립면허 자체의 이전 이외에 향후 발생되는 토지 소유권을 양도 · 양수하는 의미도 내포하고 있다. 따라서 매립면허의 양도 · 양수에 대한 평가는 특허권에 대한 권리 자체에 대한 평가 이외에 토지에 대한 평가도 고려하여야 한다. 매립면허에 대한 평가는 순수 공유수면에 대한 평가와 노출된 부지에 대한 평가로 구분하여 평가하되, 순수 공유수면은 역사적 원가방식, 노출된 부지는 변경전 매립목적을 기준으로 시장접근법을 적용하여야 한다고 판단하였다. The Public Waters Management and Reclamation Act is the governing law for public waters reclamation projects in general. The Special Act on Promotion of and Support for the Saemangeum Project is a special act of the said Act, which includes special case provisions governing supply and ownership of lands created by public waters reclamation, and transfer and acquisition of reclamation license. Neither Act, however, includes any provision on appraisal for transfer and acquisition of reclamation license. Therefore, appraisal of reclamation license needs to be conducted based on consideration of all matters and laws related. The Saemangeum Project, which this Study focuses on, involves supply of raw lands. However, since the project does not specify the concept of such raw lands, transfer and acquisition of reclamation license may include supply of raw lands. In other words, transfer and acquisition of reclamation license include transfer and acquisition of the ownership of lands in the future, as well as transfer and acquisition of the license itself. Therefore, appraisal of transfer and acquisition of reclamation license needs to be conducted based on consideration of the appraisal of the lands, as well as the appraisal of the license right itself. In light of the above, this Study concludes that appraisal of reclamation license should consist of appraisal of public waters and appraisal of the exposed sites, and the former should be conducted using the historic cost method, while the latter should be conducted using the market approach based on the original purpose of reclamation before change.

By using eyes, humans unconsciously observe what they want to observe not the whole image in their sights. The appearance of the object is a crucial task of observing-selection for an observer. The information perceived by observing will induce related actions, be memorized in the brain, and involve in recognition and recall process. This eye-tracking test set the same interior space but the different type of images such as CG and real image in an effort to compare the processes of visual-perceptions by the eye-tracking test in the different type of images. The result of the eye-tracking test illustrates intriguing concepts and relations. First, through sensibility evaluation on male and female, the male has a more distinct difference between visual-perception in real image and that in CG image than female. Second, the female has more visual-perception occurred in CG image. Third, in the image A, focused observation occurs 60 seconds in the observation-time. After the 60 seconds, the focused observation had been dramatically changed in the form of “descendingàescalatingàdescending”. In the image B, focused observation keeps decreasing in the first 50 seconds. After decreasing in the first 50 seconds, the focused observation maintains certain form “maintainingàescalatingàdescending” Forth, in the image A, left-up and left-down sections contain more observation occurrences while, in the image B, right-down section contains more observation occurrences. However, since middle and right sections contain 68.8~78.6% of observation occurrence, observation occurrences focused sections are almost identical in both types of images.
