본 논문에는 일반문서를 대상으로 하여 그 문사를 하이퍼텍스트(hypertext)로 자동변환하는 기법을 제안하고자 한다. 자동변환의 과정은 대상 문서에서 키워드(keyword)의 인식, 문서를 노드(node) 단위로 분리, 키워드로부터 노드로의 링크(ink) 생성의 3 단계로 이루어 진다. 기존의 연구에서는 문서에서 노드를 분리하는데 구문적 유사도만을 이용하는데, 본 논문에서는 양질의 하이퍼텍스트를 생성하기 위하여 구문적 유사도(syntactic similarity)뿐만 아니라 의미적 유사도(semantic similarity)를 사용한다. 구문적 유사도는 tf*idf와 벡터 곱(vector product)을 이용하고, 의미적 유사도는 시소러스(thesaurus)와 부분부합(partial match)을 이용하여 계산되어 진다. 또 링크 생성시 잘못된 링크의 생성을 막기 위하여 시소러스를 이용하여 시소러스에 존재하는 용어에 한해서 링크를 생성한다.

Multi-disk data allocation problem examined in this paper is to find a method to distribute a Binary Cartesian Product File on multiple disks to maximize parallel disk I/O accesses for partial match retrieval. This problem is known to be NP-hard, and heuristkc approaches have been applied to obtain sub-optimal solutions. Recently, efficient methods have been proposed with a restriction that the number of disks in which files are stored should be power of 2. In this paper, we propose a new disk Allocation method based on Genetic Algorithm(GA) to remove the restriction on the number of disks to be applied. Using the schema theory, we prove that our method can find a near-optimal solutionwith high probability. We compare the quality of solution derived by our method with General Disk Modulo, Binary Disk Modulo, and Error Correcting Code methods through the simulation. The simulation results show that proposed GA is superior to GDM method in all cases and provides comparable performance to the BDM method which has a restriction on the number of disks.

Purpose: The two major concerns in skin grafting are poor color match in the recipient site and the donor site morbidity. And, glabrous skin on the palmar aspect of the hands and plantar aspect of the feet attributes define the skin on the palm and fingers sole as functionally and aesthetically different from skin on other parts of the body. When there is a glabrous skin defect, it should be replaced with similar skin to restore function and aesthetics. The palmar crease areas were used to minimize these problems. The purpose of this study is to present the precise surgical technique of the full thickness skin graft using distal palmar and midpalmar creases for aesthetic better outcome for hand injuries. Methods: From May 2006 to April 2010, 10 patients with 11 defects underwent glabrous full thickness skin grafting of finger defects. Causes included seven machinery injuries, two secondary burn reconstructions, and one knife injury. Donor sites included ten glabrous full thickness skin graft from the distal palmar crease and one from the midpalmar crease. Results: Follow-up ranged from 3 months to 24 months. All glabrous skin grafts demonstrated complete taking the recipient sites and no incidence of the complete or partial loss. The donor site healed without complications, and there were no incidences of significant hypopigmantation, hyperpigmentation, or hypertrophic scarring. Conclusion: The important aspects of this method involve immediate return of glabrous skin to the defect site and restoration of the recipient site's crease by simple primary closure from adjacent skin. The glabrous skin of the palm provides the best tissue match for the reconstruction of the hands, but only a limited amount of tissue is available for this purpose. Full thickness skin grafting using palmar crease of the defects is the ideal way of reconstructing glabrous skin to restore both function and aesthetics and minimize donor site morbidity.

The Purpose of the study is to give Korean-English leaners better knowledge on vowel sounds in their learning English. The traditional description of the cardinal vowel system developed by Daniel Johns in 1917 is not enough to provide English learners with clear ideas in producing native like vowel sounds. For the reason, three Korean-native subjects, one male, one female and one child are chosen to produce 7 cardinal vowels and compare them with native English and American speaker's vowel sounds. The difference of produced vowels sounds is quantified and visualized by employing Sona-match program. The results have been fairly remarkable. Firstly, Korean-English learner's vowel sounds are articulated differently from their intention of vowel production. Secondly, the tongue positions of Koreans are placed slightly more down and forward to the lips than those of English and Americans. However, the front vowel /i/ sound is quite close to English and Americans. Lastly the mid-vowel /${\partial}$/ sound is not produced in any articulations of Korean-native speakers. It is thought that the mid vowel, /${\partial}$/ is a type of a weak sound regarded as 'schwa' which needs a great deal of exposure to the language to acquire a physical skill of articulation.

UAV의 발전에 따라 UAV영상의 활용도 늘어나고 있다. 다양한 UAV영상 기반의 어플리케이션에 점진적 번들 조정방법이 널리 사용된다. 그러나, 점진적 번들조정 방법은 중복이 없는 영상 쌍에서도 대응점을 추출해 긴 시간을 소요하게 된다. 이 과정을 효율적으로 처리하기 위해서는 중복지역에서만 대응점 추출연산을 진행해야한다. 만약 영상의 외부표정요소가 있을 경우 이를 기준으로 영상의 중복도를 계산하여 중복지역에서만 대응점 추출이 일어나도록 제한할 수 있다. 그러나 외부표정요소가 없는 영상을 활용하는 경우, 기하학적인 중복지역을 계산할 수 없으므로 다른 후보군 구성 방법의 적용이 필요하다. 본 논문에서는 외부표정 요소가 없는 경우의 대응점 추출 후보군 구성 방법들을 비교해 가장 효율적인 방법을 찾는다. 비교 방법은 일부 특징점, 특징점 군집화, 영상의 밝기를 활용한 후보군 구성방식이며 외부표정요소를 통해 구한 대응점 후보군 구성결과를 기준으로 각 방식을 비교한다. 비교 결과 일부 특징점을 활용하는 것이 가장 효율적으로 나타났다.

Camouflage is evaluated by scientific principle in the fields of biology, military science, and art. It has a strong influence on contemporary fashion and means exposure with concealment. This study analyzed the visual characteristics of camouflage patterns in fashion design through documentaries and fashion photos. The fashion design results areas follow. The simple blending of a disruptive motif indicated an inaccurate repetition of a disruptive motif, the discontinuous or continuous connection of disruptive motif, the irregular repetition of a disruptive animal silhouette, the collage of a different disruptive motif, the craft of a disruptive motif and the intensive color match of a disruptive motif. It represented the maximization of complication, fantastic and fanciness. The overlap of a disruptive motif showed the overlap of disruptive print patterns with transparency and an overlap of different fabrics with a disruptive pattern. It represented spatial relationships of three dimensions as well as the maximization of visual illusion and the reinforcement of attractiveness. The blurring of a disruptive motif showed the pointage of disruptive motif, the pointage of image, value gradation, the whole blurring of a disruptive pattern cluster and stained appearance. It represented the obscurity of motif form, the uncertainty of object and double meaning. The trompe l'oeil of a partial background object showed the realistic and the painterly imitation of color and texture for partial objects through a close-up. It represented amazement and pleasure by illusion, scarcity and the decoration of surface and synecdochical remind. In conclusion, camouflage in fashion was weakened and modified from a classical military context by a unique expression of various motifs.

This study explored the impact of beauty influencers' characteristics and product characteristics on new product acceptance intentions and studied the mediating effects of consumer trust in this process. A survey was conducted from February 22, 2021, to February 28, 2021, with Gen Y and Gen Z women in China, and 379 questionnaires were analyzed. The conclusions are as follows: First, the characteristics of beauty influencers are authenticity and expertise, similarity, attractiveness, interactivity, familiarity, and trustworthiness; product characteristics are cost, image, product quality, product perception, sales promotion, and sustainability. Second, partial beauty influencers' characteristics and partial product characteristics have a positive impact on consumer confidence and acceptance intention of the new product. Third, the mediating effect of consumer trust in the process by which beauty influencers' characteristics and product characteristics influence the intention of new product acceptance was determined. Therefore, when beauty companies use influencers in marketing, it is necessary to understand their characteristics, consider their professionality and authenticity, examine their reliability, and assess their ability to form connections with images and viewers that match their products. Additionally, to increase the acceptance intention of new products, companies should present the price of high-quality products, product sensibilities, and corporate images of products and establish measures that can positively affect consumers' acceptance intention of new products by combining them with the characteristics of beauty influencers.

생성적 적대 신경망(Generative Adversarial Networks, GAN)은 내부의 두 신경망(생성망, 판별망)이 상호 경쟁하면서 학습하는 네트워크이다. 생성자는 현실과 가까운 이미지를 만들고, 구분자는 생성자의 이미지를 더 잘 감별하도록 프로그래밍 되어있다. 이 기술은 전체 이미지 X를 다른 이미지 Y로 생성, 변환 및 복원하기 위해 다양하게 활용되고 있다. 본 논문에서는 원본 이미지에서 부분 이미지만 추출한 후, 이를 자연스럽게 다른 객체로 위변조할 수 있는 방법에 관해 기술한다. 먼저 원본 이미지에서 부분 이미지만 추출한 후, 기존에 학습시켜놓은 DCGAN 모델을 통해 새로운 이미지를 생성하고, 이를 전체적 스타일 전이(overall style transfer) 기술을 사용하여 원본 이미지의 질감과 크기에 어울리도록 리스타일링(re-styling) 한 후, 원본 이미지에 자연스럽게 결합하는 과정을 거친다. 본 연구를 통해 원본 이미지의 특정 부분에 사용자가 원하는 객체 이미지를 자연스럽게 추가/변형할 수 있음으로써 가짜 이미지 생성의 또 다른 활용 분야로 사용될 수 있을 것이다.

The time therapy in oriental medicine is to reserch physiological activity and pathological variation with time, or time with disease. In that, this therapy is to research the development of disease, progress, diagnosis, treatment, and the meaning of preventive medicine. The theory of time therapy has been developed form heaven-human corresponding principle, and fourtimes of seasons is related with human life. After that, this theory affects in yin-yang five circle principle and organ-meridian match system. The independent development was formed later, but the origin has progressed for a logn times. in relation with time therapy, traditional acupuncture therory suggested five semen. In twenty century, the doctor rheinhold voll suggested energy exchange theory, this theory is based on time therapy, but has partial differance also too. His oppinion is this´ the energy present in the body has a circulation following the acupuncture teaching, i.e., the organs and their meridians are flooded in a certain sequence by this flowing energy. This maximum times of the organs are of physiologic and pathologic significance to man. In next time, we will discuss the indivisual theory in detail, and wil have comparison, and considering too.
