This paper attempts to divide the narrative into three levels and review the approach methodology to understand Princess Bari as a narrative. If the stratification of the narrative, the analysis of each levels, and the integrated approach to them are made, this can contribute to suggesting new directions and ways to understand and study Princess Bari. The story level of Princess Bari, the surface structure, is shaped by the space movement and the chronological sequential structure of the life task that started from the birth of the main character. This story shows how a woman who was denied her existence by her father as soon as she was born finds an ontological transformation and identities through a process. Especially, the journey of finding identity is mainly formed through the events that occur through the relationship with family members. This structure, which can be found in the narrative level, forms a deep structure with the oppositional paradigm of family members' conflict and reconciliation, life and death. The thought structure revealed in this story is the problem of life is the problem of family composition, and the problem of death is also the same. In response to how to look at the unified world of coexistence of life and death, this tradition group of myths makes a relationship with man and God. This story is mainly communicated in the Korean shamanistic ritual(Gut) that sent the dead to the afterlife. Although the shaman is the sender and the participants in the ritual are the receivers, the story is well known a message that does not have new information repeated in certain situations. In gut, the patrons and participants do not simply accept the narrative as a message, but accept themselves as codes for reconstructing their lives and behavior through autocommunication. By accepting the characters and events of as a homeomorphism relationship with their lives, people accept the everyday life as an integrated view of life and death, disjunction and communication, conflict and reconciliation, and the present viewpoint. It can not change the real world, but it changes the attitude of 'I' about life. And it is a change and transformation that can be achieved through personal communication like the transformation of Princess Bari into god in myth. Thus, Princess Bari shows that each meaning and function in the story level, composition level, and communication level is related to each other. In addition, the structure revealed by this narrative on three levels is also effective in revealing the collective consciousness and cultural system of the transmission group.

Humans have adapted and evolved to natural light. However, as humans stay in indoor longer in modern times, the problem of biorhythm disturbance has been induced. To solve this problem, research is being conducted on lighting that reproduces the correlated color temperature(CCT) of natural light that varies from sunrise to sunset. In order to reproduce the CCT of natural light, multiple LED light sources with different CCTs are used to produce lighting, and then a control index DB is constructed by measuring and collecting the light characteristics of the combination of input currents for each light source in hundreds to thousands of steps, and then using it to control the lighting through the light characteristic matching method. The problem with this control method is that the more detailed the steps of the combination of input currents, the more time and economic costs are incurred. In this paper, an LED lighting control method that applies interpolation and combination calculation based on the minimum spectral power distribution information for each light source is proposed to reproduce the CCT of natural light. First, five minimum SPD information for each channel was measured and collected for the LED lighting, which consisted of light source channels with different CCTs and implemented input current control function of a 256-steps for each channel. Interpolation calculation was performed to generate SPD of 256 steps for each channel for the minimum SPD information, and SPD for all control combinations of LED lighting was generated through combination calculation of SPD for each channel. Illuminance and CCT were calculated through the generated SPD, a control index DB was constructed, and the CCT of natural light was reproduced through a matching technique. In the performance evaluation, the CCT for natural light was provided within the range of an average error rate of 0.18% while meeting the recommended indoor illumination standard.

In 2017, 1,252 cases of damages relief related to air passenger transport service were received by the Korea Consumer Agency, a 0.8% drop from 1,262 cases in 2016, the first decline since 2013. In 2017, 444 cases (35.4%) out of received cases of damages relief in the field of air passenger service received by the Korea Consumer Agency were agreed on, and out of cases that were not agreed on, the most number of 588 cases (47.0%) were concluded due to information provision and counseling, and 186 cases (14.9%) were applied to the mediation of the Consumer Dispute Mediation Committee. Major legislations that contain regulations for the damages relief and disputes resolution of air service consumers include the Aviation Business Act and the Consumer Fundamental Act, etc. The Aviation Business Act provides the establishment and implementation of damage relief procedure and handling plan, and the receiving and handling of request of damage relief by air transport businessman, and the notice of protection standard for air traffic users. The Consumer Fundamental Act provides the establishment and management of the consumer counseling organization, the damage relief by the Korea Consumer Agency, the consumer dispute mediation, and the enactment of the criteria for resolving consumer disputes. The procedures for damages relief of air service consumers include the receiving and handling of damages relief by air transport businessman, the counseling, and receiving and handling of damages relief by the Consumer Counseling Center, the advice of mutual agreement by the Korea Consumer Agency, and the dispute mediation system by the Consumer Dispute Mediation Committee. The current system of damage relief and dispute mediation for air service consumer have the problem in the exemption from obligation of establishment and implementation of damage relief plan by air transport businessman under the Aviation Business Act, the problem in the exemption from liability in case of nonfulfillment and delay of transport by aviation businessman under the criteria for resolving consumer disputes in the aviation sector, and the uppermost limit in procedure progress and completion of consumer dispute mediation under the Consumer Fundamental Act. Therefore, the improvement measurements of the relevant system for proper damage relief and smooth dispute mediation for air service consumer are to be suggested as follows: First is the maintenance of the relevant laws for damage relief of air service consumer. The exemption regulation from obligation of establishment and implementation of damage relief plan by air transport businessman under the Aviation Business Act shall be revised. To enhance the structualization and expertise of the relevant regulation for protection and damage relief of air service consumer, it will be necessary to prepare the separate legislation similar to the US Federal Regulation 14 CFR and EU Regulation EC Regulation 261/2004. Second is the improvement of criteria for resolving air service consumer disputes. For this, it will be necessary to investigate whether the cause of occurrence of exemption reason was force majeure, and distinguish the exemption from liability in case of nonfulfillment and delay of transport by aviation businessman under the criteria for resolving consumer disputes in the aviation sector, and revise the same as exemption reasons regulated under the air transport chapter of the Commercial Act and Montreal Convention 1999, and unify the compensation criteria for the nonfulfillment of transport that the substitute flight was provided and the delay of transport. Third is the reinforcement of information provision for damage relief of air service consumer. Aviation-related government agencies and concerned agencies should cooperate with airlines and airports to provide rapidly and clearly diverse information to the air traffic users, including laws and policies for damages relief of air service consumers. Fourth is the supplement to the effectiveness, etc. of consumer dispute mediation. If there is no sign of acceptance for dispute mediation, it is not fair to regard it as acceptance, therefore it will be necessary to add objection system. And if a dispute resolution is requested to another dispute settlement agency in addition to the Consumer Dispute Mediation Committee, it is excluded from the damage relief package, but it should be allowed for the party to choose a mediation agency. It will be necessary to devise the institutional measures to increase the completion rate of mediation so that the consumer dispute can be resolved efficiently through the mediation. Fifth is the introduction of the air service consumer arbitration system. A measure to supplement the limitations of the consumer dispute mediation system is to introduce the consumer arbitration system, but there are two measurements which are the introduction of the consumer arbitration under the Consumer Fundamental Act and the introduction of the consumer arbitration under the Arbitration Act. The latter measurement is considered to be appropriate. In conclusion, as a policy task, the government should prepare laws and system to enhance the prevention and relief of damages and protection of the rights and interests of air service consumers, and establish and implement the consumer-centric policy for the advancement of air service.

The Chicago Convention and Annexes have become the basis of aviation safety regulations for every contracting state. Generally, aviation safety regulations refer to the SARPs provided in the Annexes of the Chicago Convention. In order to properly reflect international aviation safety regulations, constant studies of the aviation fields are of paramount importance. Treaties duly concluded and promulgated under the Constitution and the generally recognized rules of international law shall have the same effect as the domestic laws of the Republic of Korea. Each contracting state to the Chicago Convention should meet ICAO SARPs about AOC and FAOC. According to ICAO SARPs, Civil Aviation Authorities shall issue AOC to air carriers of the state, but don't require to issue for foreign air carrier. However some contracting states of the Chicago Convention issue FAOC and/or Operations Specifications for the foreign operators. This FAOC is being expanded from USA to the other contracting states. Foreign operators have doubly burden to implement AOC of the ICAO SARPs because FAOC is an additional requirement other than that prescribed by the ICAO SARPs In Article 33, the Chicago Convention stipulates that each contracting state shall recognize the validity of the certificates of airworthiness and licenses issued by other contracting states as long as they are equal to or above the minimum standards of the ICAO. In ICAO Annex 6, each contracting state shall recognize as valid an air operator certificate issued by another contracting state, provided that the requirements under which the certificate was issued are at least equal to the applicable Standards specified in this Annex. States shall establish a programme with procedures for the surveillance of operations in their territory by a foreign operator and for taking appropriate action when necessary to preserve safety. Consequently, it is submitted that the unilateral action of the states issuing the FAOC to the foreign air carriers of other states is against the Convention. Hence, I make some proposals on the FAOC as an example of comprehensive problem solving after comparative study with ICAO SARPs and the contracting state's regulations. Some issues must be improved and I have made amendment proposals to meet ICAO SARPs and to strengthen aviation development. Operators should be approved by FAOC at most 190 if all states require FAOC. Hence, it is highly recommended to eliminate the FAOC or reduce the restrictions it imposes. In certain compliance-related issues, delayed process shall not be permitted to flight operations. In addition, it is necessary for the ICAO to provide more unified and standardized guidelines in order to avoid confusion or bias regarding the arbitrary expansion of the FAOC. For all the issue mentioned above, I have studied the ICAO SARPs and some state's regulation regarding FAOC, and suggested some proposals on the FAOC as an example of comprehensive problem solving. I hope that this paper is 1) to help understanding about the international issue, 2) to help the improvement of korean aviation regulations, 3) to help compliance with international standards and to contribute to the promotion of aviation safety, in addition.

We frequently use search engines to find relevant information in the Web but still end up with too much information. In order to solve this problem of information overload, ranking algorithms have been applied to various domains. As more information will be available in the future, effectively and efficiently ranking search results will become more critical. In this paper, we propose a ranking algorithm for the Semantic Web resources, specifically RDF resources. Traditionally, the importance of a particular Web page is estimated based on the number of key words found in the page, which is subject to manipulation. In contrast, link analysis methods such as Google's PageRank capitalize on the information which is inherent in the link structure of the Web graph. PageRank considers a certain page highly important if it is referred to by many other pages. The degree of the importance also increases if the importance of the referring pages is high. Kleinberg's algorithm is another link-structure based ranking algorithm for Web pages. Unlike PageRank, Kleinberg's algorithm utilizes two kinds of scores: the authority score and the hub score. If a page has a high authority score, it is an authority on a given topic and many pages refer to it. A page with a high hub score links to many authoritative pages. As mentioned above, the link-structure based ranking method has been playing an essential role in World Wide Web(WWW), and nowadays, many people recognize the effectiveness and efficiency of it. On the other hand, as Resource Description Framework(RDF) data model forms the foundation of the Semantic Web, any information in the Semantic Web can be expressed with RDF graph, making the ranking algorithm for RDF knowledge bases greatly important. The RDF graph consists of nodes and directional links similar to the Web graph. As a result, the link-structure based ranking method seems to be highly applicable to ranking the Semantic Web resources. However, the information space of the Semantic Web is more complex than that of WWW. For instance, WWW can be considered as one huge class, i.e., a collection of Web pages, which has only a recursive property, i.e., a 'refers to' property corresponding to the hyperlinks. However, the Semantic Web encompasses various kinds of classes and properties, and consequently, ranking methods used in WWW should be modified to reflect the complexity of the information space in the Semantic Web. Previous research addressed the ranking problem of query results retrieved from RDF knowledge bases. Mukherjea and Bamba modified Kleinberg's algorithm in order to apply their algorithm to rank the Semantic Web resources. They defined the objectivity score and the subjectivity score of a resource, which correspond to the authority score and the hub score of Kleinberg's, respectively. They concentrated on the diversity of properties and introduced property weights to control the influence of a resource on another resource depending on the characteristic of the property linking the two resources. A node with a high objectivity score becomes the object of many RDF triples, and a node with a high subjectivity score becomes the subject of many RDF triples. They developed several kinds of Semantic Web systems in order to validate their technique and showed some experimental results verifying the applicability of their method to the Semantic Web. Despite their efforts, however, there remained some limitations which they reported in their paper. First, their algorithm is useful only when a Semantic Web system represents most of the knowledge pertaining to a certain domain. In other words, the ratio of links to nodes should be high, or overall resources should be described in detail, to a certain degree for their algorithm to properly work. Second, a Tightly-Knit Community(TKC) effect, the phenomenon that pages which are less important but yet densely connected have higher scores than the ones that are more important but sparsely connected, remains as problematic. Third, a resource may have a high score, not because it is actually important, but simply because it is very common and as a consequence it has many links pointing to it. In this paper, we examine such ranking problems from a novel perspective and propose a new algorithm which can solve the problems under the previous studies. Our proposed method is based on a class-oriented approach. In contrast to the predicate-oriented approach entertained by the previous research, a user, under our approach, determines the weights of a property by comparing its relative significance to the other properties when evaluating the importance of resources in a specific class. This approach stems from the idea that most queries are supposed to find resources belonging to the same class in the Semantic Web, which consists of many heterogeneous classes in RDF Schema. This approach closely reflects the way that people, in the real world, evaluate something, and will turn out to be superior to the predicate-oriented approach for the Semantic Web. Our proposed algorithm can resolve the TKC(Tightly Knit Community) effect, and further can shed lights on other limitations posed by the previous research. In addition, we propose two ways to incorporate data-type properties which have not been employed even in the case when they have some significance on the resource importance. We designed an experiment to show the effectiveness of our proposed algorithm and the validity of ranking results, which was not tried ever in previous research. We also conducted a comprehensive mathematical analysis, which was overlooked in previous research. The mathematical analysis enabled us to simplify the calculation procedure. Finally, we summarize our experimental results and discuss further research issues.

ERT imaging, especially 3-D method, is a very powerful means to obtain a very high resolution image of the subsurface for geotechnical or hydrogeological problems. In this paper, we introduce two examples of successful case histories, where the imaging targets were three-dimensional. First example is the case of 3-D fracture imaging for hydrogeologic application. In this example, the borehole deviation was a critical problem in the ERT imaging and we could obtain real 3-D attitude of fracture system by including the borehole deviation in the inversion. In the second case, we did field experiment to image the empty tunnel with the size of $2m{\times}2m$ and the target was very clearly imaged in 3-D space. In these examples, we could show that 3-D ERT imaging is a very powerful tool for the 3-D subsurface imaging and the method can provide enhanced imaging capabilities especially for the 3-D targets such as fractures and cavities or tunnel.

The stability assessment of a concrete liner of a compressed air storage tunnel should be performed by an approach which is different from that commonly used for the liners of road tunnels, since the liner is exposed to high air pressure. In this study, the stability analysis method for the liner of compressed air storage tunnel is proposed based on the elastic and elasto-plastic solutions of the thick-walled cylinder problem. In case of elastic analysis, the yield initiation condition at the inner boundary is considered as the failure condition of the liner, while the condition which results in the extension of yielding zone to a certain depth is taken as a failure indicator of the liner in the elasto-plastic analysis taking Mohr-Coulomb criterion. The application of the proposed method revealed that the influence of the relative magnitude of boundary loads on the stability of liner is considerable. In particular, noting that the estimation of the outer boundary load may be relatively difficult, it is thought that the precise prediction of outer boundary load is very important in the analysis. Accordingly, the emphasis is put on the selection of the liner installation time, which may govern the magnitude of outer boundary load.

Local color transfer is the process of assigning a given color to a local region in a target image. The local region that contains the given color has to be segmented. Conventionally, the segmentation of the corresponding local region in a target image is based on the color distance. The region which is the closest in color distance is separated. However, since the close range of color distance separating a given color from target image is ambiguous and uncertain, color distortion is often generated around a separated local region. Therefore, this paper addresses the problem of segmentation in a local color transfer. To prevent color distortion, a modified color influence map is proposed with color categories. First, the target image is roughly segmented using a color category map, which groups similar colors in color space. It restricts the color transfer to a specific color category according to a given color. Second, modified color influence map assigning different weight to lightness and chroma, respectively, is used instead of Euclidian color distance. Then, by combining a modified color influence map and color category map filtered with anisotropic diffusion, a local region that contains a given color can be segmented more strictly than conventional method.

Changing of industry structure and development of traffic and telecommunications requires a change of the knowledge about the space where the human beings reside. Step by step the world is being divided into specified utility blocks. Today there is a limit that only one local government can compete with another region in the world. This study provides decision support tools with the use of GIS on the regional level for regions competition. GIS establishes regions and analyzes their geographic environment data, which will help in local-government problem solving and provide framework data for similar regions to become the community. The wide-area GIS application can present an objective and rational basis for regulation of inefficient investments and excessive competition between adjacent regions. The study area is Gangwon-do. Considering specific features of Gangwon-do which preserved high-quality environment resources, river basins were taken as a basis among natural regional elements. The main object of analysis conducted were the facts relevant to environmental regulation. The Gangwon-do consists of three regions in this study: Yongdong region, North-Hangang region and South-Hangang region. The analysis of each region regulation cases showed the following: in Youngdong region the forests regulation rate is high, in North-Hangang region the military installations protection sector's rate as well as regulation rate for water resources protection is relatively high, in South-Hangang region the forest and water resources regulation rate is high. The percentage of forests and water regulation rate appeared to be rather high in Gangwon-do, which means that the value of forest and water resources there is very high.

Localizing an object in image is a common task in the field of computer vision. As the existing methods provide a detection for the single object in an image, they have an utilization limit for the use of the application, due to similar objects are in the actual picture. This paper proposes an efficient method of object localization for image recognition. The new proposed method uses color correlation back-projection in the YCbCr chromaticity color space to deal with the object localization problem. Using the proposed algorithm enables users to detect and locate primary location of object within the image, as well as candidate regions can be detected accurately without any information about object counts. To evaluate performance of the proposed algorithm, we estimate success rate of locating object with common used image database. Experimental results reveal that improvement of 21% success ratio was observed. This study builds on spatially localized color features and correlation-based localization, and the main contribution of this paper is that a different way of using correlogram is applied in object localization.
