Despite its ecological importance of wetlands in our life, wetlands around cities and villages have been steadily disappearing. It is mainly due to either natural geological changes or man-made causes such as permitted land zone changes for the purpose to convert to agriculture land. This study aims to establish a comprehensive database of wetlands using GIS in a historic conservation city Gongju City. The systemic data management would enable to identify distribution of wetlands and their ecological attributes, and to estimate the conservation value of the wetlands. The data base will be able to use in strategic way to preserve the local ecological areas for local residents and tourists and manage the quality of wetlands in the historic and conservation city. For the purpose, it is suggested organising a wider network with not only local residents but local authorities and relevant stakeholders would be beneficial. This study also recommends that long-term strategic plan to preserve the existing wetlands. This study findings as a seminal case example can be used to apply to other geographical areas of the country and can contribute to create a national ecological nature map as well as evaluate the attributes and quality of natural ecosystem service of the region.

This study illustrates the necessity and feasible process of constructing local collections in public libraries. One of the important responsibilities of public libraries is to collect, preserve, and provide local information in order to enhance the identity of the region and local culture and to maintain and preserve the social memory of the community. However, as the subjects and types of local information are diverse and are owned and scattered by various persons and organizations in the local community, it is difficult to collect materials and build collections. There is, as a result, a lot of confusion in the library field. Focusing on the case of a few public libraries that hold good local collections, this study attempted to add suggestions to build a local collection containing regional history and locality and to promote related services.

Lower lip reconstruction in cases with a full-thickness defect over one-third of the vermilion is challenging. Numerous conventional techniques have been applied with unsatisfactory surgical outcomes because of microstomia and oral commissure blunting due to shortened horizontal lip length. Herein, we present a case in which a full-thickness lower lip defect of more than one-third of the horizontal lip length was covered with a novel mucosal roofing flap reconstruction to minimize the loss of horizontal lip length and to preserve mouth opening. No recurrences or metastases were observed during 3 years and 6 months of follow-up, with horizontal lower lip length maintained and mouth opening of 2.5 finger breadths.

In pace with the development of network technology at lightning speed, social networks have been extensively applied in our lives. However, as social networks retain a large number of users' sensitive information, the openness of this information makes social networks vulnerable to attacks by malicious attackers. To preserve the link privacy of individuals in social networks, an uncertain graph method based on node random response is devised, which satisfies differential privacy while maintaining expected data utility. In this method, to achieve privacy preserving, the random response is applied on nodes to achieve edge modification on an original graph and node differential privacy is introduced to inject uncertainty on the edges. Simultaneously, to keep data utility, a divide and conquer strategy is adopted to decompose the original graph into many sub-graphs and each sub-graph is dealt with separately. In particular, only some larger sub-graphs selected by the exponent mechanism are modified, which further reduces the perturbation to the original graph. The presented method is proven to satisfy differential privacy. The performances of experiments demonstrate that this uncertain graph method can effectively provide a strict privacy guarantee and maintain data utility.

We present improved deformation energy to enhance the visual quality of a shape deformation technique, where we preserve the local structure of an input planar shape. The deformation energy, in general, consists of several constraints such as Laplacian coordinate constraint to preserve the quality of deformed silhouette edges, mean value coordinates and edge length constraints to preserve the quality of deformed internal shape, and user-specified position constraints to control the shape deformation. When the positions of user-specified vertices change, shape deformation techniques compute the positions of the other vertices by means of nonlinear least squares optimization to minimize the deformation energy. When a user-specified vertex changes its position rapidly, it is frequently observed that the visual quality of the deformed shape decrease rapidly, which is mainly caused by unnecessary enlargement of the Laplacian vectors and unnecessary change of the edge directions along the boundary of the shape. In this paper, we propose improved deformation energy by prohibiting the Laplacian and edge length constraints from changing unnecessarily. The proposed deformation energy incorporated with well-known optimization technique can enhance the visual quality of shape deformation along the silhouette and within the interior of the planar shape while sacrificing only a little execution time.

This is case comments of several representative legal cases regarding self- determination right of patient. In a case in which an intoxicated patient attempted suicide refusing treatment, the Supreme Court ruled that the medical team's respect for the patient's decision was an act of malpractice, and that in particular medical situations (medical emergencies) the physician's duty to preserve life supersedes the patient's rights to autonomy. Afterwards, at the request of the patient's family, and considering the patient's condition (irrecoverable death stage, etc.) consistent with a persistent vegetative state, the Supreme Court deduced the patient's intention and decide to withdraw life-sustaining treatment. More recently, regarding patients who refuse blood transfusions or other necessary treatment due to religious beliefs, the Supreme Court established a standard of judgment that can be seen as conferring equal value to the physician's duty to respect patient autonomy and to preserve life. An empirical study of legal precedent with regard to cases in which the physician's duty to preserve life conflicts with the patient's autonomy, grounded in respect for human dignity, can reveal how the Court's perspective has reflected the role of the patient as a decision-making subject and ways of respecting autonomy in Korean society, and how the Court's stance has changed alongside changing societal beliefs. The Court has shifted from judging the right to life as the foremost value and prioritizing this over the patient's autonomy, to beginning to at least consider the patient's formally stated or deducible wishes when withholding or withdrawing treatment, and to considering exercises of self determination right based on religious belief or certain other justifications with informed refusal. This will have a substantial impact on medical community going forward, and provide implicit and explicit guidance for physicians who are practicing medicine within this environment.

Article 77 sets forth the principle of prevention applied in several legal systems. Under this principle the party threatened by ooss as a consequence of a breach of contract by the other party is not permitted to await passively incurrence of the loss and then sue for damages. He is obliged to take adequate preventive measures to mitigate his loss. If the injured party abstains from taking such excessive measures he will not be considered to have failed to mitigate the loss under Article 77. The sanction provided in Article 77 against a party who fails to mitigate his loss only enables the other party to claim reduction in the damages. The reduction in damages under Article 77 is equal to the amount by which the loss should have been mitigated if the injured party had taken reasonable measures to avert or to lessen it. The aim of Article 77 is to encourage mitigation of the loss. The duty to mitigate the loss applies not only to a breach of contract in respect of an obligation whose performance is currently due. but also to an anticipatory breach of contract under Article 71. Article 85 contemplates that the buyer is in delay in fulfilling the latter obligation, or else that he fails to pay the price when payment is to be made concurrently with delivery of the goods by the seller. In both these situations of default, the seller who is either in possession of the goods or otherwise able to control their disposition must take measures, reasonable in the circumstances, to preserve them. The right of retention of the goods y the seller exists until he is reimbursed by the other party for the reasonable expenses incurred. Article 87 and Article 88 of the Convention grant different rights to the party obligated to take steps to preserve the goods; Article 87 allows him to deposit them in the warehouse of a third person, and Article 88 to sell them by whatever means appropriate. A difference exists between paragraph Article 88 (1) which grants the right to sell, and paragraph (2) which imposes the duty to take reasonable measures to sell the goods.

This study investigated the status of disaster response, focusing on modern architecture. The modern architecture is drawing more attention and being more used in the local community among the architectural heritage in downtown collective. The railway employee residence area in Soje-dong, Daejeon is a collective building group, and the efforts to evaluate and preserve its historical, cultural, and architectural values have been underway. However, the area is now an undesignated cultural property that does not receive institutional protection. It carries significance in preserving it as a collective building group. Yet, since the main structure is made of wood, the risk of being destroyed by fire or disaster is high, and disaster prevention measures are insufficient. Therefore, this study examined the structural and non-structural conditions such as the arrangement and architectural characteristics of official residence buildings, and looked into measures of the construction of a disaster prevention system and residents' participation. To preserve the urban historical environment created as a collective architectural heritage, it is necessary that the area reinforces its own disaster prevention capabilities, such as establishing an effective disaster prevention system considering village characteristics, strengthening disaster prevention capabilities based on residents' participation, and forging formal and informal governance in the local community.

There is a clear need to enhance the attractiveness of rural areas by leveraging their core assets to respond to emerging mega-trends. This paper analyzes the progress of the direct payment program that has been implemented to preserve agricultural landscapes in rural areas, using spatial information data. The study identified the planting characteristics of landscape crops, spatial utilization characteristics of the system, and utilization characteristics of the system by the beneficiaries. According to the analysis, the spatial utilization characteristics of the system could be classified into eight types: tourism resources and nearby agricultural areas, designation across the entire rural area, agricultural areas around villages, large-scale agricultural areas, small-scale agricultural areas, scattered and dispersed areas, independent parcels of land, and ranches. Based on the characteristics and limitations of the landscape preservation direct payment system, this study provides directions for future rural specialized zones. The landscape preservation direct payment system focuses on income support for farmers and providing agricultural benefits in terms of public interest. Meanwhile, the landscape agricultural zone serves as a rural specialized zone, highlighting the need to explore the direction of integrated rural landscape management. It is important for farmers, as the key stakeholders, to preserve the agricultural landscape in rural areas. Forming community-level cooperatives and engaging in relevant activities are crucial for achieving this goal. In order to actively preserve the agricultural landscape, it is necessary to consider the resumption of financial support for village landscape preservation activities, along with the designation of landscape agricultural zones. There is a need to conduct a specific review and explore measures to accommodate the designated landscape complexes at the local government level. The higher the ratio of designated landscape complexes, the more agricultural landscape management based on public value has been carried out. The designation of such landscape complexes can be seen as a demand for voluntary utilization of agricultural landscapes in the region. Moreover, as the ratio of designated landscape complexes increases, it becomes evident that farmers at the village level actively participate in agricultural landscape preservation and contribute to providing public value or utilize it as a tourism resource. This highlights the need for managing agricultural landscapes at the village level within the appropriate context.
