  • Accidents in which oil spills occur intermittently in the ocean due to ship collisions and sinkings. In order to prepare prompt countermeasures when such an accident occurs, it is necessary to accurately identify the current status of spilled oil. To this end, the Coast Guard patrols the target area with a fixed-wing airplane or helicopter and checks it with the naked eye or video, but it was difficult to determine the area contaminated by the spilled oil and its exact location on the map. Accordingly, this study develops a technology for direct ortho-rectification by automatically geo-referencing aerial images collected by the Coast Guard without individual ground reference points to identify the current status of spilled oil. First, meta information required for georeferencing is extracted from a visualized screen of sensor information such as video by optical character recognition (OCR). Based on the extracted information, the external orientation parameters of the image are determined. Images are individually orthorectified using the determined the external orientation parameters. The accuracy of individual orthoimages generated through this method was evaluated to be about tens of meters up to 100 m. The accuracy level was reasonably acceptable considering the inherent errors of the position and attitude sensors, the inaccuracies in the internal orientation parameters such as camera focal length, without using no ground control points. It is judged to be an appropriate level for identifying the current status of spilled oil contaminated areas in the sea. In the future, if real-time transmission of images captured during flight becomes possible, individual orthoimages can be generated in real time through the proposed individual orthorectification technology. Based on this, it can be effectively used to quickly identify the current status of spilled oil contamination and establish countermeasures.

  • In this study, a survey of public library librarians was conducted to examine the current librarian's job status by conducting a survey on the library's environment, such as the size of books, number of employees, and operating subjects. As a result of the study, it was found that based on the current job content and recognition, librarians are mainly working in the order of operating reading culture programs, planning reading culture programs, and user information services. In addition, it can be seen that librarians highly value the importance of their respective duties, and in the case of labor intensity, more than half of them recognize that the current labor intensity is high. Among the detailed competency units corresponding to each task in the future, more appropriate competency unit elements should be considered in consideration of the essential competency, additional supplementation, and lower factors through this study. In addition, the higher the number and experience of regular workers in the library, the higher the degree of librarian certification, and the higher the current position, the higher the importance, difficulty, and expertise of the current work, so it is expected that the library should continue to build experience in the future.

  • Due to the development of communication technology and expansion of Intelligent Transport System (ITS), the car is changing from a simple mechanical device to second living space which has comprehensive convenience function and is evolved into the platform which is playing as an interface for this role. As the interface area to provide various information to the passenger is being expanded, the research importance about smart car based user experience is rising. This study has a research objective to propose the guidelines regarding the smart car user experience elements. In order to conduct this study, smart car user experience elements were defined as function, interaction, and surface and through the discussions of UX/UI experts, 8 representative techniques, 14 representative techniques, and 8 locations of the glass windows were specified for each element. Following, the smart car users' priorities of the experience elements, which were defined through targeting 100 drivers, were analyzed in the form of questionnaire survey. The analysis showed that the users' priorities in applying the main techniques were in the order of safety, distance, and sensibility. The priorities of the production method were in the order of voice recognition, touch, gesture, physical button, and eye tracking. Furthermore, regarding the glass window locations, users prioritized the front of the driver's seat to the back. According to the demographic analysis on gender, there were no significant differences except for two functions. Therefore this showed that the guidelines of male and female can be commonly applied. Through user requirement analysis about individual elements, this study provides the guides about the requirement in each element to be applied to commercialized product with priority.

  • Phone segmentation of speech waveform is especially important for concatenative text to speech synthesis which uses segmented corpora for the construction of synthetic units. because the quality of synthesized speech depends critically on the accuracy of the segmentation. In the beginning. the phone segmentation was manually performed. but it brings the huge effort and the large time delay. HMM-based approaches adopted from automatic speech recognition are most widely used for automatic segmentation in speech synthesis, providing a consistent and accurate phone labeling scheme. Even the HMM-based approach has been successful, it may locate a phone boundary at a different position than expected. In this paper. we categorized adjacent phoneme pairs and analyzed the mismatches between hand-labeled transcriptions and HMM-based labels. Then we described the dominant error patterns that must be improved for the speech synthesis. For the experiment. hand labeled standard Korean speech DB from ETRI was used as a reference DB. Time difference larger than 20ms between hand-labeled phoneme boundary and auto-aligned boundary is treated as an automatic segmentation error. Our experimental results from female speaker revealed that plosive-vowel, affricate-vowel and vowel-liquid pairs showed high accuracies, 99%, 99.5% and 99% respectively. But stop-nasal, stop-liquid and nasal-liquid pairs showed very low accuracies, 45%, 50% and 55%. And these from male speaker revealed similar tendency.

  • This study attempted to examine the ambiguity of work from the legal, social perspective, and actual performance differences in domestic nursing work compared to foreign countries. We compared the historical background of nurses' expanded work through overseas situations, compare and analyze the legal basis for nurses' qualifications and work in each country, and what changes they have undergone to clarify their work. Through this, we would like to consider the current status of the absence of a legal basis for professional work of domestic nurses and seek a direction for the development of domestic medical care. This study applied the case study method as one of the comparative institutional research methods. Among OECD countries, developed countries such as the United States, Australia, and Japan were selected and compared among developed countries that are solving medical gaps using nurses. In the United States, Australia, Japan, and Korea, nurses' professional work has been created by changes in the medical environment due to an aging society, chronic diseases, and lack of doctors. We looked at the start of their professional work, the establishment of legal grounds, the timing of qualification recognition, the development of the credential system and scope of work. Foreign countries have legal grounds for their roles and tasks, but domestic countries are before legislation. The country still has not narrowed the gap between the position of the legislative and judicial branches and actual work, and the current status of the domestic healthcare system has been measured through overseas development cases.

  • Wild ginseng, grown in undisturbed forest environments, has been maintained for centuriesthrough human intervention and knowledge, leading to the development of current ginseng agriculture. The practice of ginseng farming has long been established in various regions of Korea. However, the ginseng farming specifically in Geumsan was recognized as a Globally Important Agricultural Heritage System (GIAHS) by the Food and Agriculture Organization of the United Nations (FAO) in 2018. This designation was granted after a thorough evaluation, which confirmed that Geumsan's ginseng farming met the necessary criteria, including historical importance, traditional knowledge system, agrobiodiversity, and agricultural landscape. Traditional ginseng farming in Geumsan practices the 'rotating agriculture system', a sustainable land use approach that has been developed over several cycles of long duration (10-15 years). It contains the knowledge to choose locations for cultivation that prioritize the direction of sunlight and wind circulation. Furthermore, it received significant recognition for its agricultural heritage value based on its maintenance of several traditional knowledge systems, including ancestral wisdom and knowledge regarding pre-planting field management techniques. As of December 2023, there are currently 86 locations in 26 nations that have been designated as GIAHS. Among these sites, Geumsan stands out as the first and only site in the world specifically recognized for the cultivation of ginseng crops. This historical record serves as a significant reminder of Korea's prominent position as a major producer of ginseng on a global level. This article first provides an overview of the concept of agricultural heritage, the designation criteria, and the status of the designation. It then identifies, among the GIAHS designation criteria, the agricultural heritage value of traditional ginseng farming in the Geumsan region from the perspective of local traditional knowledge systems.

  • Power plant engineering industry obtains EPC plan project and delivers results about electricity, measurement, machinery, and piping and so on. Its works are taken by projects. Although power plant engineering composes 2~5% of whole EPC project cost, it's one of the fundamentals because it affects process after planning step a lot. However, domestic power plant engineering companies' project performance ability is insufficient and there's a need for systematic performance. Thus, this study defined related factors of successful performance and analyzed the priority among them through analytical hierarchy process. All respondents recognized experience, knowledge, and communication as important factors. Administrators considered knowledge, experience, and communication. But hands-on workers considered experience, knowledge, human resources. Those who have experience in oversea project considered process, experience, human resources. However those who don't have experience in oversea project considered knowledge, experience, and communication. Recognition of important factors varies by the position and work experience of members.

  • This article examines the theory of mutual resonance (感應論) of Dasan (茶山), Jeong Yak-yong (丁若鏞), and Jeungsan (甑山), Kang Il-sun (姜一淳), who lived during the transition to modernity in Joseon. By examining the philosophical thought of Dasan and Jeungsan, which centered on the problem of realizing morality through the resonance (感應) between human beings and Sangje, this article aims to reveal that their religious discussion of resonance, which is differentiated from the rational theory, ultimately strengthens the practice of morality. Dasan and Jeungsan argue that it is difficult to overcome human selfish desires through the mind alone, which aims for moral autonomy, so the recognition of a transcendent being, Sangje, becomes necessary. Since Sangje, the Supreme Being, is always watching over human life, one can examine one's deficiencies with reverence and correct them. In particular, Dasan and Jeungsan reveal that humans and Sangje do not exist independently, but are in touch with each other through the heart, so that moral practice can be actualized in reality. Dasan and Jeungsan do not position humans and the Supreme Being as independent entities, but rather allow them to organically resonate with each other through the mind, enabling individuals to engage in moments of contemplation and reflection at every juncture of choice, unbound by time and space. From this perspective, the resonance theory of Dasan and Jeungsan can be seen to have practical implications for integrating moral practice into everyday life. The thought systems of Dasan and Jeungsan should be understood as embodying the anguish and sincerity of two figures who sought to convey to future generations the path of moral practice that humans must walk, based on a reverent mindset towards the Supreme Being, amidst tumultuous domestic and international circumstances.

  • According to the available data, in these days, the number of medical accidents and disputes have significantly increased since 1990 in Korea. From this aspect, a variety of approaches and efforts to solve these problems is needed before it is too late. This study intended to identify the thoughts of patients who are directly connected with medical accidents and disputes and then to consider reasonable settlement methods of the increasing disputes. For achieving the purpose of this study, the self-administerd questionnaire was conducted with 450 out-patients who visited three university hospitals, five small and medium-sized hospitals, and ten clinics in Seoul from June 13 to 17, 2005. Incomplete questionnaires were omitted and 410 respondents(91%) were included for the analysis of this study. Each section of the survey was composed of six categories such as the recognition of malpractice, a compensation system about no-fault medical accidents, the recognition of the judgement of medical accidents in court, reasonable settlement of medical accidents, reasons of lawsuit, and the need of the medical dispute settlement organization. The major results of this study were as follows. First, more than half of the respondents, 51.9 percent, worry about malpractice. And many respondents think malpractice causes their symptoms to persist or become worse, and also some respondents think that the doctor's prescription changed too frequently. Second, as for a compensation system about no-fault medical accident, 55.7 percent of the respondents insist that a proper compensation for suffering patients or their families should be provided. And also as for the responsibility of compensation, respondents think joint compensation of both the medical institution and the government is needed foremost, followed by the medical insurance company and finally by the medical institution. The government as well as the related institutions should take responsibility for malpractice accidents for which the doctor is not responsible. Third, as for the acknowledgment of medical accident judgements by the court, 32.8 percent of respondents think that it is best to compromise with a medical institution, followed by lawsuit(26.2%), the assistance of civil organization(23.2%), and a powerful physical protest(7.6%). Fourth, as for the lawsuit of medical accidents, 62.9 percent of respondents think that patients and their families would be in a disadvantageous position in relation to medical institutions and doctors mentioning the lack of professional medical and lawful knowledge, experience and know-how as the reason. So many people have given up appeals owing to the difficulties involved in defending themselves through evidence. Fifth, about a half share of the respondents indicated that the medical institution's neglect of the responsibility of medical accidents is one of the most important reasons of lawsuit. And next respondents mentioned the lack of the medical dispute settlement organization and a general distrust of medical institutions and doctors. Sixth, a majority of respondents consented to the introduction of the need of the medical dispute settlement organization, And about a half of the respondents mentioned a readiness to accept the mediation of the organization, but the rest did not express a clear opinion. It seems that conflict among the parties concerned have existed in relation to the medical dispute settlement organization and related legislation for many years. But as this study has shown, the needs of the medical dispute settlement organization is in desperate demand. Therefore, more negotiation efforts from all interest groups should be considered for the birth of the medical dispute settlement organization and related legislation.

  • This study is to explain social capital characteristics of Filipino immigrant women at the level of neighborhood. This research targeted Filipino immigrant women in the metropolis, small town and rural area in Korea to find out the relevance of individual property and characteristics of the community and social capital of neighboring communities- school community, cathedral community, etc- through measurement of the participants' recognition. This study reveals that differences exist in the relationship between length of residence and social capital in the school community and the catholic church community. There is a significant positive relationship between length of residence and political factors in the catholic church community, thereby having a better relationship with longer period of stay, while length of residence and confidence show a negative trend in the school community, leading to less confidence. The catholic church community holds a dominant position in homogeneity, cohesion, and the amount of social capital. According to the findings, social capital 'relation' is more closely related to homogeneity of the community, 'norms' to cohesion. 'Relation and norms' and 'confidence and politics' factors are recognized similarly in both communities, thus resulting in the recognition that decision making within the community, the share of value, and observance of social norms approximate a friendly relationship among members, and satisfaction level, emotional support, and confidence among members approach politics that members can talk about their personal matters. It is noted in the research process that the symbolism of the cathedral community as a transnational circuit behavior occurs where collective culture and personal desires of Filipino immigrant women were combined with production of social capital. Filipino immigrant women's awareness of community and social capital appearing in the cathedral community show that not only residence, along with the cultural identity of Filipino immigrant women, but also collective social and cultural characteristics, such as 'family reunion' can not be overlooked. In particular, at this time when discussion and debate on the interculturalism over multiculturalism is heating up, communal spirit and social capital based on the ethnic identity are important in that they can be a crucial path to the cross-cultural interaction with our society, therefore, a study on the social capital of the ethnic community needs to be encouraged and extended to more diverse communities, to the space of the multilayered scale.
