  • Microstructure evolution including morphological change in the vicinity of the electrodes, porosity change and grain boundary migration was observed in polycrystalline CoO subject to electric fields at 1100 and 121$0^{\circ}C$ in air. At the cathode, the transported cations react with oxygen in the surrounding to form new lattices, while, at the anode, the reverse reaction occurs leading to lattice annihilation. Lattice formation also takes place at the surface of pores near the cathode inducing pore-filling effect. Grain boundary migration was found bo be enhanced or retarded depending on the field direction. It is therefore implied that the driving force of grain boundary migration is the vectorial sum of the curvature-induced chemical potential gradient and the electric field applied.

  • The digital color image can be distorted by noise for a transmission or other elements of system. It happens to vague of a boundary side in the division of a color image object, especially, boundary side of an input color image is very important because it can be determined to the division and detection element in pattern recognition. Therefore it is boundary part In this paper, it detects the optimal edge with applying this color image to WCNN algorithm, after it does level up a boundary side of a color image by using the adaptive morphology as the threshold of an input color image. Also, it is used not a conventional fixed mask edge detection method but variable mask method which is cal led a variable BBM. It is confirmed by simulation that the proposed algorithm can be got the batter result edge at the place of closing to each edges and having smoothly curved line.

  • This paper presents a new algorithm that extracted lung region in X-ray and enhanced the region. With a lung region that was extracted by histogram threshold value, it was diffi cult to detect perfect lung boundary. Therefore we presented perfect lung boundary detection method using apex detection and apex region restoration. Also, by applying modified equalization algorithm and presented function to inside of lung region, we want to give help to automatic diagnosis In X-ray chest image. Presented main line trace algorithm gave good result in detection of lung boundary And, as apex detection method using lung row and column gray level average value found more correct place of lung than the rpethod of prior algorithm, we succeeded perfect lung region detection, Also, presented function that had lung region's gray level distribution characteristic was very effective to image enhancement.

  • In this paper, I would like to explore the possibility that the nature of place assimilation can be captured in terms of the OCP within the Optimality Theory (Mccarthy & Prince 1999. 1995; Prince & Smolensky 1993). In derivational models, each assimilatory process would be expressed through a different autosegmental rule. However, what any such model misses is a clear generalization that all of those processes have the effect of avoiding a configuration in which two consonantal place nodes are adjacent across a syllable boundary, as illustrated in (1):(equation omitted) In a derivational model, it is a coincidence that across languages there are changes that have the result of modifying a structure of the form (1a) into the other structure that does not have adjacent consonantal place nodes (1b). OT allows us to express this effect through a constraint given in (2) that forbids adjacent place nodes: (2) OCP(PL): Adjacent place nodes are prohibited. At this point, then, a question arises as to how consonantal and vocalic place nodes are formally distinguished in the output for the purpose of applying the OCP(PL). Besides, the OCP(PL) would affect equally complex onsets and codas as well as coda-onset clusters in languages that have them such as English. To remedy this problem, following Mccarthy (1994), I assume that the canonical markedness constraint is a prohibition defined over no more than two segments, $\alpha$ and $\beta$: that is, $^{*}\{{\alpha, {\;}{\beta{\}$ with appropriate conditions imposed on $\alpha$ and $\beta$. I propose the OCP(PL) again in the following format (3) OCP(PL) (table omitted) $\alpha$ and $\beta$ are the target and the trigger of place assimilation, respectively. The '*' is a reminder that, in this format, constraints specify negative targets or prohibited configurations. Any structure matching the specifications is in violation of this constraint. Now, in correspondence terms, the meaning of the OCP(PL) is this: the constraint is violated if a consonantal place $\alpha$ is immediately followed by a consonantal place $\bebt$ in surface. One advantage of this format is that the OCP(PL) would also be invoked in dealing with place assimilation within complex coda (e.g., sink [si(equation omitted)k]): we can make the constraint scan the consonantal clusters only, excluding any intervening vowels. Finally, the onset clusters typically do not undergo place assimilation. I propose that the onsets be protected by certain constraint which ensures that the coda, not the onset loses the place feature.

  • There is no provision regarding the 'litigation on land boundary' under the Korean laws. Therefore, there are disputes in theory with respect to its nature, requirements for litigation, criteria for determination, etc., and it is necessary to establish the provisions of the law on this issue in the future. For this legislation, it is necessary to conduct a comparative consideration on laws of other countries which have completed the relevant provisions. This study, as a first step, researches a history of litigation for determination of boundary under the Roman law and medieval law, and furthermore introduces the German law which has relatively completed legal provisions on litigation for determination of boundary. In addition to common ownership litigation, the German law has established a provision on litigation for boundary as a judicial procedure considering a special place, called as a dispute on ownership of adjacent land, on the assumption that it is difficult or impossible to prove the boundary. The primary purpose of this litigation is to clarify a true boundary, and if such clarification is impossible, a boundary is discretionally created in accordance with the statutory standards under Article 920 of the German Civil Act (BGB). It means creation of the scope of land ownership by operation of decision, not only by the 'discovery of original boundary'. Both cases are different from each other in the aspect of judicial decision, but embracing them into one is a lawsuit for determination of boundary under the German law. Under the Korean legislation, it is necessary to make a theory containing two different criteria for determination into a single type of litigation, considering such aspects.

  • Korean peninsula has a long history and a geopolitical location as a buffer tone, which has provided the conditions for cultural dynamism and diversity across space and time. The changing processes of place names in Korea is considered to be better suited to the study on cultural politics that is interested in the culture wars over the meaning of culture among different social subjects. In order to ensure the legitimacy of cultural politics for the study of place names in Korea, this study attempts to make a theoretical construction based on the concepts of place identity, territorial contestation, and the politics of scale. Cultural and linguistic theories to be best applied to the study of place names in Korea are the theories on Angehm's and Castells' identity, $P{\hat{e}}cheux's$ identification, Hall's decoding, and Voloshinov's ideological sign. Power relations involved in the inclusion and exclusion are necessarily concerned with the process of constructing a place identity or territorial identity by means of a place name, which represents identity and ideology of a social subject. In the examination of this process, it is necessary to take the elements of identity, ideology and power relations into consideration. In this study, therefore, the politics of scale is experimented for its applicability in the study of place name in Korea, which is expected to accommodate concepts of boundary, territory, territoriality and territorialization. In the end, it is suggested in this study that a series of basic and interdisciplinary studies on the cultural politics of place names in a range of area should be undertaken along with the enough theoretical knowledge of cultural politics.

  • This study attempts to present a new interpretation of the Jeju province Waga, authorized as Jeju province Folklore, in the context of lifestyles of residents distinctive in the Jungji, Chatbang, and Gopang system. Study results uncovered that (1) only one Jungji, a traditional house kitchen, exists in one house boundary, in the form of detached building in the 4 units of Gaok (K-2 Gaok, K-3 Gaok, C-1 Gaok, and C-2 Gaok) (2) Chatbang had multifaced-functions; as a place for diet for mistress and children, a place for preparing meals for a mister who diet in the room, and as an auxiliary meal-preparation facility in time of domestic celebration day. (3) Gopang was mostly a place for grain storage, and K-3 Gaok has one unit, K-1 Gaok, C-1 Gaok, and C-2 Gaok had 2 units, and K-2 Gaok and H Gaok had 3 untis of Gopang. (4) Jungji and Chatbang were correlated for meal preparation and diet while activity-line of flow was divided each other. (5) Jungji and Gopang were located at the opposite edges of of each house, revealing no consideration of indoor activities. (6) The ratios of space of Jungji, Chatbang and Gopang out of the whole house space were, average 23% in the case of Jungji located in the inner house, and average 37% in the case of Jingji located in the detached building, average 14% larger in the case of detached Jungji system.

  • The comtemporary architecture has not an discourse on form and representative style, but a new architectural concept of the generative process through the various relationship of the urban context, the continuity of the time and the experience of the people. This architectureal concepts make new and various architectural attempts to have a virtuality. The viruality is a reality to coexist with the present in contemporary philosophy. Daniel libeskind makes various arhcitectural experimentative attempts to reveal his virtuality through his memory as the Jews and his unconscious virtuality. The 'line' has the connotation of architectural reality and virtuality. Every line drawn becomes architectural form for example, walls, windows and makes spaces, and reveal a boundary as a connection. Architecture's visibility understates and structures its invisible aspect, so that the visible and the invisible make the architecture together. Daniel libeskind maks the virtual lines having the invisible of unconsious, time, and place. He no longer divide the form of architecture, its spatiality from all the implications which it adresses beyond its own particular built time and place and public unconsious mind. He demands the 'virtual line' that remembers distress and the past and reveal the virtuality of time and place. The virtual line is the sentimental communication of architecture.

  • In 1995 the land development was executed in Songchon-dong, Daejeon-si, and the region lost the strong geographical and historical character as an old clan village of the Song family who has great influence over the country in the Josun Dynasty. Though many cultural assets related to the Song family are preserved during the land development, the region fails to keep the authentic sense of place because the preservation was fulfilled only based on the boundary of each specific buildings. The Dongchundang park is an example to reveal the issue. Besides the fact that it is the Designated Treasure, the Dongchundang has an important meaning for having been the center of the clan and its local community in Songchon-dong. While the Dongchundang park built during the land development contains the Dongchundang with closely related buildings, the Dongchungoteak and Youngurk Song's House for the purpose of preserving the historical assets, the park was planned in an irrelevant way to the place. This study investigates the discrepancy between the past and the present condition of the park and proposes a guideline to alleviate the discrepancy as to retrieve the park's genuine sense of place.

  • The development of digital culture has brought radical change in the fundamental concept of what workspace is defined by and has also switched the cognition of workspace originally being a place to spend time and do activities regarding tasks into space more than just that. If we take a look at the cases overseas firms have announced after the year 2000, we can find distinguishing facts different from the existing workspace composition, like creative workspace, amusement workspace, workspace for communities, etc. Thereupon, the goal of this research is to look into the domestic characteristics of workspace by investigating and analyzing case by case targeting domestic firms. This research is to first comprehend the theoretical study of workspace, the changing environment, and the characteristics of domestic workspace, going on to utilizing the information achieved above to analyze 8 appointed domestic firms as examples. Contemporary domestic workspace is defined not a place only for activities regarding work tasks but rather a place comfortable and friendly in the concept of a second residence, community node for sharing knowledge and information, mobile space for the digital nomads, and space for coincidental encountering and communication. Based on this the analyzed characteristics of contemporary domestic work places are metaphor, convergence, beyond boundary, and emergence. The characteristics mentioned above are considered elements that increase corporate profits by managing efficient smart-work and producing creative ideas. Therefore, I believe continuous research and development related to this subject is necessary.
