내부클러스터를 이용한 개선된 FCM 알고리즘에 대한 연구

안강식,조석제,Ahn, Kang-Sik,Cho, Seok-Je 한국정보처리학회 2002 정보처리학회논문지B Vol.9 No.2

In this paper, we propose a modified FCM (MFCM) algorithm to solve the problems of the FCM algorithm and the fuzzy clustering algorithm using an average intracluster distance (FCAID). The MFCM algorithm grants the regular grade of membership in the small size of cluster. And it clears up the convergence problem of objective function because its objective function is designed according to the grade of membership of it, verified, and used for clustering data. So, it can solve the problem of the FCM algorithm in different size of cluster and the FCAID algorithm in the convergence problem of objective function. To verify the MFCM algorithm, we compared with the result of the FCM and the FCAID algorithm in data clustering. From the experimental results, the MFCM algorithm has a good performance compared with others by classification entropy. 본 논문에서는 FCM알고리즘과 평균내부거리를 적용한 퍼지 클러스터링 알고리즘의 문제점을 해결하기 위하여 개선된 FCM 알고리즘을 제안한다. 개선된 FCM 알고리즘은 내부클러스터를 이용하여 클러스터 크기가 다른 경우에도 크기가 작은 클러스터에 일정한 소속정도를 부여할 수 있다. 그리고 이에 맞는 목적함수를 설계하고 검증한 후 데이터 분류에 사용하기 때문에 목적함수의 수렴성 문제를 극복할 수 있다. 그러므로 클러스터 크기가 다른 경우에 발생하는 FCM 알고리즘의 문제점과 목적함수의 수렴성에 문제가 있는 평균내부거리를 적용한 퍼지 클러스터링 알고리즘의 문제점을 해결할 수 있다. 제안한 알고리즘을 검증하기 위하여 제안한 알고리즘을 이용하여 데이터를 분류한 결과를 FCM 알고리즘, 평균 내부거리를 적용한 퍼지 클러스터링 알고리즘을 이용하여 데이터를 분류한 결과와 각각 비교하였다. 실험을 통하여 제안한 알고리즘으로 데이터를 분류할 경우 분류 엔트로피에 의해 기존의 알고리즘들보다 더 좋은 결과를 나타냄을 알 수 있었다.

This paper proposes a new color image recovery method based on the color constancy algorithm. This method uses a color constancy model which represents the characteristics of human visual system. The most important process of color constancy model is the estimation of the spectral distributions of illuminant of an input image. To estimate of the spectral distributions of illuminant of an input image, we use the brightest pixel values and the values of surface reflectance of an input image using a principal component analysis of the given munsell chips. We estimate a CIE tristimulus values of an input image using the estimated spectral distributions of illuminant and recover an image by scaling it regularly. From the experimental results, the proposed method was effective in recovering the color images.

Welfare idea orientation can become guides and lines for welfare policy. The purpose of this paper is to ascertain if college students have any welfare idea orientations among the various ideologies(conservatism, mid-right, mid-left, radical socialism). To know it, This paper randomized, aggregated and analyzed 794 college students. The results to analyze them are to discover the point that college students' welfare idea orienation lean toward middle-left. Especially they have the more radical welfare idea orientation about IMF and welfare budget problem than any other areas. In contrast with it, they have moderate middle-right conscious orientation about unemployment problem. Additionally speaking, The significant difference of welfare idea orientation among background variables comes out in intercollege field(p<.05).

경제위기하의 복지정책의 변화 : 영국의 경험 Experience in England

전일주,안강식 진주산업대학교 1998 論文集 Vol.37 No.-

This paper is to seek the wisdom about the direction and response of the welfare policy in Korea by examining closely the change of the English welfare policy in the past as history teaches the wisdom. The contents of this paper are to compare the ideologies, organizations, programs and finances of welfare in England before and after the economic crisis. First of all I can discover the distinguished changes in ideologise, organizations and programs of welfare and discover the constant and incremental change in terms of finances. Especially It is in contrast to the intention of the Thatcher government that it shows us constant and incremental change in the financial aspect. The case of the change of the welfare policy in England is not of general application in our welfare policy. However, There is any inkling. The economic crisis in England is attributable to the expanding welfare expenditures but our economic crisis has its origin in political corruption, undeveloped monetary situation and wasteful importation of foreign capital of the financial cliques, I think. Therefore, the method to deal successfully with the economic crisis is differs from country to country. We ought to not cutback the welfare expenditures. If not so, our level of welfare will go down more and more. We have to change the welfare policy drastically to emancipate the poverty class through the increase of welfare expenditures.

Local governmetns ought to supply the various kinds of services that can satisfy diversely administative demands of their inhabitants. Comparing with the deficiency of finance, technology and ability in local governments, the needs of inhabitants are blowing up . Therefore the third sector as a service-supply system is required to tide over the financial troubles in local government. As the history of the third sector is not long since it was put into effect, this monograph may not generalize the results discovered by the concrete case study. Bearing this point in mind, I am to consider problems of the third sector, and to present the activation plans to problems of the third sectors. The of this paper are as follows : Ⅰ. Introduction Ⅱ. Theoretical background of the third sector as service-supply system. Ⅲ. Present condition of the third sectors. Ⅳ. Problems and Activations of the third sector. Ⅴ. Conclusion.

地方自治 實施以後의 福祉行政傳達體系의 變化와 合理的 方案에 관한 硏究

The welfare service delivery system in Korea has been centralized in top-down style. The functions of welfare have been dispersed with the central public administration organizations as well as the Ministry of Health and Welfare. And then the welfare service delivery system has not been specialized because of human and organizational factors within the bureaucracy. But I thought the local autonomy, especially the direct election of the heads of local government would have incurred the change of welfare service delivery system. However I didn't discover any other change except the change of the name of the local and central welfare organizations. For that reason, I scrutinize the various models, which are composed of two determinants(One is the degree of independence of welfare function from the local autonomous entity, the other is whether or not of the seperation of health and welfare function). Among these models, I recommend the ministry of health and welfare -the bureau of health and welfare- the office of health and welfare model(model6). This model has the advantages of the specilization of welfare administration, the cordination among welfare service organizations, the integration of services, and the participation of clients. These strengths are in accord with the ideas of local autonomy. The contents are as follows: Ⅰ. Introduction Ⅱ. Theoretical background of welfare service delivery system Ⅲ. Present condition and problems Ⅳ. Rational alternative of welfare service delivery system Ⅴ. Conclusion

福祉國家 危機와 對應

오시환,안강식 진주여자전문대학 1995 論文集 Vol.18 No.-

The growth of the welfare state has continued during 1940-60 due to Keynes-Beverdge theories and each nation has preffered to introduce theories. But The times of the growth of the welfare state faded away because of the stagflation in 1970s. and so the crisis of the welfare state began to appear. The main purpose of this paper is not only to examine the crisis of the welfare state, but also to make alternative responses to the crisis that the welfare state confronts. The perspectives of the welfare state in crisis consist of neo-conservatism, neo-marxism and pragmatism. In fact, The critiques of the welfare in crisis aimed at the middle Road(social democratic theory, Fabian Social democracy theory). Three perspectives regard the cause of the welfare state in crisis as the over-expended spendings. Of course, The factors of overloaded expenditures differ depending upon these perspectives. While neo-conservatism attributes deficit finance to the the growth and overload of the government, Neo-marxism refers to the contradiction of the capatal accumulation and the legitimacy. Pragmatism thinks it as the fallacy in implementing the social welfare policy. The alternative responses to the welfare state in crisis are as follows. First, Neo-Marxism maintains to cutback the government expenditures, especially social welfare expenditures. Second, Neo-Marxism points to give up the capitalism itself because of the contradicton of the capitalism. Trird The pragmatic and social democratic perspectives maintained by Mishra is corporatism. This means the consensus politics which the laboror, the entrepreneur, and the government do decision-makings about the social welfare policy, and share responsibilities. Finally the welfare pluralism relates to the neo-conservatism but this means that the subjects of the wlfare services are to be state as well as non-state.(voluntary association, market, household). In a nutshell, It seems that the model of the desirable welfare state dosen't exist. Even so, The pursuit of the welfare state as an ideal type can never be paused. Because the welfare is the final aim toward which humanbeing can pursue.
