In the conventional clustering algorithms, an object could be assigned to only one group. However, this is sometimes not the case in reality, there are cases where the data do not belong to one group. As against, the fuzzy clustering takes into consideration the degree of fuzzy membership of each pixel relative to different classes. In order to overcome some shortcoming with traditional clustering methods, such as slow convergence and their sensitivity to initialization values, we have used the Harmony Search algorithm. It is based on the population metaheuristic algorithm, imitating the musical improvisation process. The major thrust of this algorithm lies in its ability to integrate the key components of population-based methods and local search-based methods in a simple optimization model. We propose in this paper a new unsupervised clustering method called the Fuzzy Harmony Search-Fourier Transform (FHS-FT). It is based on hybridization fuzzy clustering and the harmony search algorithm to increase its exploitation process and to further improve the generated solution, while the Fourier transform to increase the size of the image's data. The results show that the proposed method is able to provide viable solutions as compared to previous work.

Objectives : Through the analysis of the harmonization(和) thought in Traditional Chinese culture, and then excavate the theory and application of Harmonization Method(和法) in Huang Di Nei Jing(黃帝內經) and Shanghan Zabing Lun(傷寒雜病論). Methods : We find the harmonization(和) means harmony and neutral in traditional Chinese culture, including the harmony of society, the harmony of the mind and the body, and so on. Results : Huang Di Nei Jing(黃帝內經) emphasized the health status is moderate, the disease state is unbalance, preserving our health should keep the yin-yang equilibrium, treating disease should reestablish the equilibrium status, which establish the foundation of the theory of Harmonization Method(和法). Shanghan Zabing Lun(傷寒雜病論) created the methods of settlement and harmony, which is a precedent for the wide application of Harmonization Method(和法) for future generations, including to reconcile the interior-exterior and yin-yang, to harmony the ying-wei and qi-blood, to reconcile the activities of qi of internal organs. Conclusions : The harmonization(和) is the ideological foundation of the theory system of TCM and the Harmonization Method(和法). The Harmonization Method(和法) is an important treatment method for clinical practice of Traditional Chinese Medicine.

In the Japanese garden, a unique planting design has been used to improve visual harmony with the surrounding landscape by planting plants around the objects that are not harmonious with surrounding landscape. In this study, physiopsychological effects of plants caused by a traditional planting skill used in Japanese garden was verified in terms of visual relaxation using eye movement recording and semantic differential method. A total of fourteen Japanese volunteers(seven male and seven female) who have normal vision(aged $21{\sim}28$) participated as subjects. Experiment was carried out in the sealed room of Chiba University in Japan. Four different types of scenery models were presented which were created by combination of the three landscape factors of the surrounding background, the object that disturbs visual harmony, and the trees planted for improving visual harmony with the surrounding landscape. In the results, significantly more gaze fixations were measured on the trees than on the object and higher values in positive feelings were recorded for the stimuli with proper planting combination. Our results indicated that proper tree planting can cause physiopsychological relaxation by improving visual harmony with the surrounding landscape and provided new evidence for supporting scientific validity of the traditional planting skills.

Harmony Search(HS) algorithm is an emerging meta-heuristic optimization algorithm, which is inspired by the music improvisation process and has been successfully applied to solve different optimization problems. In order to further improve the performance of HS, this paper proposes a new method which is called Fast Harmony Search(FSH) algorithm. For the purpose, this paper suggest a method to unify two independent improvisation processes by newly defining the boundary value of a object variable using HM. As the result, the process time of the algorithm is shorten and explicit decision of bandwidth is no more needed. Furthermore, exploitative power of random selection is improved. The numerical results reveal that the proposed algorithm can find better solutions and is faster when compared to the conventional HS.

This study evaluated the degree of harmony of food pairing with Korean traditional liquors according to the taste and flavor. In-depth interviews were performed with eight experts from May 7 to 17, 2016, to screen Korean traditional liquor and food. For traditional liquor, Sanseong-makgeolli, Hansansogokju, Damsol, Gamhongro, and Andong Soju were chosen. For foods, pan-fried beef, squid with vinegar dressing, clam soup, honey-filled rice cake, prune, grilled mushroom, Swiss cheese, pistachio, honey, and chocolate cake were chosen. Harmonization of the analytical results Sanseong-makgeolli, between honey and Pan-fried Beef achieved the most harmonious results. Hansansogokju with honey and prune were harmonious. Damsol and Gamhongro, which are distilled liquor and containing added ingredients, were perfect matched with chocolate cake and squid with vinegar dressing. In the degree of harmony between Andong Soju and food, it was confirmed that squid vinegar and Swiss cheese were the most harmonious. Through the results of this study, it was found that the degree of harmony with food was different depending on the characteristics of alcoholic beverages. In addition, it is believed that not only taste and flavor, but also the alcohol content of alcoholic beverages will play an important role in the harmony with food.

지금까지 건조된 jacket 중에서 가장 큰 것으로 알려진 미국 Exxon사의 Harmony jacket 이 현재 현대 중공업에 의해 제작되고 있다. Harmony jacket은 제작완료 후 울산으로부터 미국 California서안의 Santaynez해역으로 운송될 예정인데, 이와 같이 긴 해상운송시에 jacket과 seafasening 부재들은 피로에 의하여 상당히 손상을 입을 수 있다. 본 연구에서는 두가지의 가능한 운송항로에 대해, jacket과 tie-down 부재가 받는 피로에 의한 손상정도를 계산하고 그 결과를 비교 하였다. 몇 가지 가정하에 행하여진 해석 결과에 따르면, 피로에 의한 손상을 적게 주는 운송항로는 Hawaii를 경유하는 남쪽할로이며, 운송 barge와 인접하는 부분, 특히 barge 양단 부근의 jacket joint들이 손상을 받기 쉽다는 것을 알 수 있다.

The purpose of this study is to identify the color combination characteristic and to find out the characteristics of color tones in interior environments of Korean traditional houses. The results of the interior color combination analysis, it was revealed that contrast was the most dominant in architectural elements color. In the furniture, graduation, contrast and analogous harmony were mainly used. Single color harmony, analogous harmony, complementary harmony were the dominant color combination characteristics in interior accesories. Color tones of architectural elements were dull and light(pale, light grayish, light grayish) and color tones of furniture were dark and dull(dull, dark, dark grayish). However, interior accessories of an-bang show wide range of color tones raging vivid to dark tone, while sarang-bang accessories have tendency to soft, gray and dull tones. Therefore, the color tones of an-bang and sarang-bang elements show clear differences.
