  • It is difficult to combine oriental and western medicine. Each medicine has a different academic background, perspective on the world, and studying methodology. The claim that two paradigms can not be combined is not obtained from an actual verification, but this means it is so hard to combine two medicines having different backgrounds. The amalgamation of oriental and western medicine should be phased in on the basis of the continuous reciprocal understanding and commitment. First, the strength and weakness of each medicine over the treatment and research are required to be identified. Then, a few complementary areas can be chosen enabling a trial of fusion on a small scale. A cycle of problem solving and a new research can be set by analyzing research results obtained through the implementation over a period of time. In other words, the researchers of oriental and western medicine should repeat a continuous and gradual complementary research process by identifying issues to be improved and complemented through a consensus. Once the methodology obtained through the process of problem solving and proficient implementation is established in a stable condition, a method to widen the fusion area by expanding the operating area and implementation method can be chosen. However, the integral system of oriental medicine shouldn't be substituted by mechanical idea or reductionism. What should be done primarily for oriental medicine is to objectify things through quantification. In particular, the oriental treatment should accept the microscopic diagnosis to determine the structure and observe the biochemical change.

  • Purpose: This study aims to comprehensively analyze what small business owners experience in relation to stressors, consequences, coping methods, and situational factors. Research design, data and methodology: In this study, qualitative research methodology was used to conduct in-depth interviews with 15 small business owners who started franchise convenience stores, and classify stressors and consequences, coping methods, and situational factors based on the transactional theory of stress. Results: The results of this study are as follows. First, stressors were classified into challenge stressor and hindrance stressor. Second, stress coping methods were classified into problem-focused and emotion-focused coping methods. Among them, SBOs mainly used problem-focused coping methods. Third, consequences were classified into physiological, emotional, and behavioral tension. Lastly, the moderating factorsin the process of stress coping were resilience, social support, and positive traits. Conclusion: Theoretically, the stressors and coping methods that small business owners experience during the start-up process were confirmed from an integrated theoretical perspective. Practically, building trust relationships with SBOs and providing realistic job introductions are required at the head office level, and on the individual side, efforts are required to strike an appropriate balance between behavioral and emotional stress coping and to form a consensus with family members.

  • In this paper, we propose a new feature matching algorithm which is robust to the viewpoint change by using the FAST(Features from Accelerated Segment Test) feature detector and the SIFT(Scale Invariant Feature Transform) feature descriptor. The original FAST algorithm unnecessarily results in many feature points along the edges in the image. To solve this problem, we apply the principal curvatures for refining it. We use the SIFT descriptor to describe the extracted feature points and calculate the homography matrix through the RANSAC(RANdom SAmple Consensus) with the matching pairs obtained from the two different viewpoint images. To make feature matching robust to the viewpoint change, we classify the matching pairs by calculating the Euclidean distance between the transformed coordinates by the homography transformation with feature points in the reference image and the coordinates of the feature points in the different viewpoint image. Through the experimental results, it is shown that the proposed algorithm has better performance than the conventional feature matching algorithms even though it has much less computational load.

  • Purpose: The injection of various materials, including medical fillers and unregulated products, is widespread, potentially causing the development of foreign body granulomas. Should this occur on the nose, the contour deformity and inflammatory signs that result from these granulomas are aesthetically undesirable to patients. The purpose of our study is to share our experiences using different surgical approaches, depending on the affected portion of the nose, to optimize management of this challenging problem and to evaluate patient's satisfaction using our in-house questionnaire along with degree of improvement by two independent plastic surgeons. Methods: We treated 18 patients who underwent surgical excision of nasal foreign body granulomas via a perilesional approach to the lesion (n=12) or by transcolumellar incision (n=6) at our hospital over a period of seven years from March 2003 to October 2010. Nonparametric statistics were used and are presented as medians (25th-75th). Patient satisfaction was evaluated on a scale of 1 to 5 using an in-house questionnaire. All pre-and post-operative photographs were analyzed by two independent plastic surgeons. Post-operative outcomes were evaluated based on the surgeons' consensus ratings. Results: All patients receiving the transcolumellar approach reported a high level of satisfaction with the results. All but two patients who received the perilesional approach were satisfied with the outcome. No outcomes were rated as no change or worse by the consensus ratings. Conclusion: For the upper two-thirds of the nose, perilesional surgical excision can lead to substantial patient satisfaction with modified contour deformity and infection control. The transcolumellar approach resulted in better outcomes and patient satisfaction for the lower one-third of the nose.

  • The Communications, Oceanography and Meteorology Satellite(COMS) will be launched in 2008. Ground processing for COMS includes the process of automatic image navigation. Image navigation requires landmark detection by matching COMS images against landmark chips. For automatic image navigation, a matching must be performed automatically However, if matching results contain errors, the accuracy of Image navigation deteriorates. To overcome this problem, we propose use of a robust estimation technique called Random Sample Consensus (RANSAC) to automatically detect erroneous matching. We tested GOES-9 satellite images with 30 landmark chips that were extracted from the world shoreline database. After matching, mismatch results were detected automatically by RANSAC. All mismatches were detected correctly by RANSAC with a threshold value of 2.5 pixels.

  • This paper examines research ethics in using the generative AI ChatGPT for research purposes. After reviewing traditional themes of research ethics and relevant principles, it will be argued to be inappropriate to discuss ChatGPT-related issues only from the perspective of permission, detection, and punishment. We need to consider the fundamental problem that the current rules pose concerning the way ChatGPT works. This leads to the proposal that the usage of ChatGPT should be clearly noted when it is used for research purposes and that some unresolved issues should be recognized. Although the advantages of ChatGPT cannot be denied, consensus on the appropriate scope of use is needed from perspectives of the research community and researcher's social responsibility. As generative artificial intelligence technologies are still in the early stages of development, researchers should pay attention to relevant research ethical issues, while not making hasty conclusions. In the conclusion, it will be also proposed to discuss and make a consensus regarding the definition of research that is premised on existing research ethics, but challenged with the advent of ChatGPT and AI technology.

  • This study explores the discoures of family and family policy in the legislative process of Strong Family Act. Critical discourse analysis was used. The results are follows. The Strong Family Act made family issue as a political agenda in spite of much critics. The characteristics of the family discourse in "strong family camp": 1) The emphasis on the moral principle in family 2) denial of deinstitutionalization of family 3) regarding the family problem as a moral and individual problem 4) regarding the state as managing and controling the family. The characteristics of the family discourse in "critical camp": 1) strong family discourse is related to "the family" ideology 2) regarding the family problem as a social, structural problem 3) regarding the state as subsiding, supplementing families. The characteristics of the family policy discourse in "strong family camp": 1) casual efficiency as justifying logics 2) family policy as means to recover family values 3) deunifying the family policy. On the one hand, the characteristics of the family policy discourse in "critical camp": 1) social consensus and academic discussion as justifying logics 2) regarding the family policy as a means of gender equality and strategical point of welfare state expansion. The discourse of family and family policy, especially 'Strong Family Discourse" resulted in conjugation of nationalism and neoliberalism.

  • One of the systematic attempts for technological forecasting is Delphi Method that externalizes and manipulates unformalized experts opinion in a particular problem or subject. It has, however, a critical shortcoming that it can not reflect the degree of interaction that exists among forecast events or subject. Gordon and Hayward(1969) criticize that when the forecast events are strongly interrelated, a totally unrealistic consensus may result. They proposed a new forecasting method that considers the interaction of events, that is, Cross Impact Analysis (CIA). A number of related models have been developed after them. In this study, we examine a variety of research results related to CIA obtained by literature survey and propose the limitation and future research direction. This analysis would be expected to help us to create a strategic scenario on future technology development at the government and firm level.

  • Deregulation is not a matter or problem to be resolved simply by revising a law or a system in a short period of time. Rather, it should be implemented at a steady pace on the basis of a full understanding of the relationships between government regulation and the government's role, taking into account the inherent functions of the market. Moreover, arguments about government regulation and its deregulation vary according to viewpoints and approaches on the part of parties concerned. This makes it more difficult to form a consensus or reach a conclusion in recognizing and resolving the basis of problems at issue. This paper aims to review the shipping industry deregulation of major countries, to analyze Korea's situation and problems of shipping regulation, and to suggest it's improving methods. Although government regulation is a sensitive policy issue, this paper remains relatively at the basic research. Regulation problems should be tackled by interdisciplinary approach. A specific approach in regulation study could not explain exactly the causes and results of government policy
