In Korea ,little attention was paid to chiggers until 1950 so only to reports on four species of chiggers were pulished before Korean War. Since 1950 (beginning of Korean War), a marked progress in the study of chiggers has been made in connection with investigations of Epidemic hemorrhagic fever occurring among the United Nations troops which was suspected as a chigger-borne infectious disease and the first report of tsutsugamushi disease in Korea called natives attention to chiggers as the vector mites of this newly known disease in Korea. This paper is mostly based on specimens of author's collections from 3269 Rodentia Insectivora, 9 Chiroptera, 24 Aves , 35 Amphibia and 3 Reptilia during the time from December 1955 to December 1956 but four species were introduced here from works of others . There are reported here five species of chiggers previously known only out of Korea and a new species also. This new species was collected by author but Lipovsky informed his colleague had collected the same one in Korea and they would publish it as new one in near future. This is the reason of describing the new species without specific name . Of course, this paper is incomplete in view of the geographic distribution, seosonal change and host relation etc, but will serve as a brief summary of the chiggers fauna of Korea up to the present. This species described here are as follows : Gahrliepia brennani var. ventralis Neoschongastia posekanyi Euschongastia kigtajimai Euschongastia miyagawai Euschongastia koreaensis Trombicula nagayoi Trombicula japonica Trombicula pomeranzevi Trombicula mitamurai Trombicula tamiyai Trombicula palpalis Trombicula orientalis Trombicula pallida Trombicula scutellaris Trobmicula miotis Trombicula hiranumai Trombicula sp. Trombicula hiranumai Trombicula sp. Trombicula subintermedius Shunsennia tarsalis . Euschongastia ikaoensis . Trombicula koomori Trombicul subakanushi

Mobile crowd-sensing (MCS) is a promising sensing paradigm that leverages mobile users with smart devices to perform large-scale sensing tasks in order to provide services to specific applications in various domains. However, MCS sensing tasks may not always be successfully completed or timely completed for various reasons, such as accidentally leaving the tasks incomplete by the users, asynchronous transmission, or connection errors. This results in missing sensing data at specific locations and times, which can degrade the performance of the applications and lead to serious casualties. Therefore, in this paper, we propose a missing data inference approach, called missing data approximation with probabilistic tensor factorization (MDI-PTF), to approximate the missing values as closely as possible to the actual values while taking asynchronous data transmission time and different sensing locations of the mobile users into account. The proposed method first normalizes the data to limit the range of the possible values. Next, a probabilistic model of tensor factorization is formulated, and finally, the data are approximated using the gradient descent method. The performance of the proposed algorithm is verified by conducting simulations under various situations using different datasets.

본 논문에서는 멀티미디어 콘텐츠 보호에 대한 반공모 코드를 위한 동적 멀티미디어 핑거프린팅 코드를 설계하는 알고리즘을 제안한다. 기존의 반공모 코드(ACC: Anti-Collusion Code)를 위한 멀티미디어 핑거프린팅 코드는 BIBD(Balanced Incomplete Block Design)의 접속행렬을 보수행렬로 변환하여 k를 k+1로 증대시키는 수리적 방법으로 설계되었다. 그리고 보수행렬의 코드벡터를 사용자에게 핑거프린팅 코드로 부여하고, 콘텐츠에 삽입하였다. 제안된 알고리즘에서는 사용자가 구매하는 콘텐츠로부터 특징점을 추출하고, 이를 기반으로 동적으로 핑거프린팅 코드를 설계할 수 있도록 BIBD의 v와 k+1 조건을 만족하는 반공모 코드의 후보성 코드를 코드북(Codebook)에 구축하고 ${\lambda}+1$ 조건을 만족하는 행렬(이하, Rhee행렬이라 함.)을 생성한다. 실험을 통하여 콘텐츠의 특징점 기반으로 생성된 Rhee행렬의 코드벡터는 v비트의 유의수준 ($1-{\alpha}$)에서 신뢰구간에 k가 존재하며, Rhee행렬의 각 행과 행, 열과 열 사이의 유클리디안 거리가 BIBD 기반의 보수행렬과 그래프 기반의 보수행렬과 같은 k값이 산출되었다. 더욱이 Rhee행렬의 첫 행과 첫 열은 생성과정에서 초기 점화벡터로 콘텐츠 포렌식 마크 정보가 되며, 이와 관계가 있는 나머지 코드벡터들과의 관계성이 코드북에 기록되어 있기 때문에, 공모된 코드를 추적할 때 원 핑거프린팅 코드의 상관관계 계수를 구할 필요 없이 코드북의 탐색으로 공모자를 추적이 용이하다. 따라서 본 논문에서 생성된 Rhee행렬은 수리적으로 생성된 BIBD 기반의 행렬보다 ACC로서 강인성과 충실도가 우수하다.

Purpose: In an amputated auricle, a microvascular anastomosis is the best treatment of choice. But, the neartotally amputated auricle which is connected by very narrow tissue pedicle to the head, can survive by simple attachment without a microvascular anastomosis owing to the rich vascular network through the superficial temporal artery and posterior auricular artery. In cases of venous congestion resulting from a lack of vein anastomosis, medical leeches (Hirudo medicinalis) can solve the problem. We are reporting the case of a 6-year-old boy who had a neartotally amputated auricle with successful results by simple closure and medical leech treatment without a microvascular anastomosis. Methods: A 6-year-old male patient had an left auricular injury by an escalator accident. The left auricle was neartotally amputated from the temporal head with connection only by very narrow skin and subcutaneous pedicle (about 1 cm in width) at the helical root of upper and anterior part of auricle. Marginal bleeding from the avulsed auricle was noted and the arterial blood was supplied from a branch of upper auricular branch of the superficial temporal artery. The auricle was repaired by simple closure including cartilage and skin without any vascular anastomosis. After simple closure, the auricle showed good circulation with pink color. But on the 2nd day after the operation, there was a venous congestion with severe swelling, which resulted in a purplish colored auricle. The venous congestion disappeared after using medical leeches by the 5th day after the operation. Results: The repaired auricle showed aesthetically and functionally satisfactory result with normal development at the 9 months follow-up check after the operation. Conclusion: In cases of neartotally amputated auricles of children or crushing injury in which microsurgery is difficult, we can try simple closure with the use of medical leeches in treating a of venous congestion for a successful result.

This dissertation is to help understanding about the emergence of active children's clothes in the latter part of the 18th century in England. In previous ages children had not been look-ed upon as children, but as incomplete and in-ferior men and women, the costume of children had not been distinguishable from that of their elders. The early eighteenth-century chil-d could not play in comfort because they dressed like their parents. But in the third quarther of the eighteenth century children became free from their con-comfortable and became active. English chil-dren's clothes was prevailing even in Europe as well. In the background of this liberation, there were many enlightened ideas, such as philosophers of enlightenment, doctors, writers, educators. Among these John Locke and Jean Jacque Rousseau criticized openly about rampant fashion which was distorting the body by corset and hoop. Rousseau was the one who wrote$\boxDr$Emile$\boxUl$and played the most important role to free children from an old fashioned idea, and emphasized to bring up children by the natural process of mental and physical development as human beings are a part of nature. Fashion reflects politic, economic, social, ideology, culture of the days and these factor function to create fashion which shows“Time Spirit”.Children's clothes, like those of their parents, follow the fashion, but with a difference, the form of which varies with the attitude to the child. Thus this dissertation was to study in relation with the background of the times in the latter part of 18th century in England and Rousseau's Naturalism in connection with the emergence of active children's clothes. The result is that diffusion of the idea of freedom and equality, the growth of bourgeoisie, the development of clothing and tex-tile industry have influenced to the emergence of active children's clothes. Also a great deal of middle and high class parents devoted to their children's education and was influenced by Rousseau's Naturalism. Specially the bourgeoisie who made their fortune by their own effort were eager to educate their achievement and business by their children through education. This factor influenced to the children's clothes as well.

Trompe-1’oeil technique strategically conceived with a view to effectively realize creative ideas among the expression techniques of fine arts style has provided the driving force in development of fine arts and has continuously influenced development of the modern fashion pursuing unique individuality. The purpose of this study is to open a new horizon for the development of fashion as a practical art, and to seek the expansion of the creative domain and ultimately to contribute to the creation of original and creative fashion by examining the interrelationship between Trompe-1’oeil, which has long been utilized and positioned as one of the leading fine arts techniques with the advent of surrealism in the beginning of the 20th century and the modern fashion. The study is focused first on finding out how Trompe-1’oeil technique originated in connection with researching the fashion of Trompe-1’oeil and on analysing the techniques of expression, and then on investigating into Elsa Schiaparelli, pioneer of Trompe-1’oeil technique to identify her influences, and finally on classifying clothes employing Trompe-1’oeil technique by their expression method to examine how Trompe-1’oeil technique has been applied to modern clothes. As for the research method, the researcher has referred to fine arts books, collection of pictorial records and the like to gain conceptual understanding of Trompe-1’oeil and to examine the expression method and the features of Trompe-1’oeil, and collected and referred to fashion books and fashion marazines to understand Elsa Schiaparelli and the expression tendencies of Tromprf-1’oeil in modern fashions. Particularly, the researcher has attempted to search the correlation between modern fashion and Trompe-1’oeil technique. As a result of this research, the researcher has managed to classify Trompe-1’oeil technique expressed in modern fashion into ‘harmony’, ‘application of the human body’, ‘front and back’, ‘surface and inside’. ‘completion of the incomplete’ and ‘detail.’ The researcher has also noted that Elsa Schiaparelli, a surrealist first applied Trompe-1’oeil technique to clothes and confirmed that quite a few avant-garde clothes designers following Elia Schiaparelli, by using Trompe-1’oeil technique in clothes, recently recreate fresh feelings.

This study examined the characteristics of total consumers' anti-sites on on-line and their changes according to the establishment year of consumers' anti-sites, the activities and the evaluation of consumers' anti-sites and their differences according to the characteristics of consumers' anti-sites. Total 649 consumers' anti sites were analyzed for examining the characteristics of total consumers' anti-sites and 18 anti sites were selected for examining the activities and the evaluations of consumers' anti site. The anti sites were evaluated by the index of using in preceding research. The result showed that about 90% of total consumers' anti-site were not activated, only a few consumers participated even in the activated sites, most activity of the anti-site were operated only on on-line not off-line, over half of anti-sites targeted to the company in the type of the subject of anti-site, and the majority of the external shape of anti-site were cafe. On the change of characteristics according to the opening year, the proportion of cafe and the sites acting on both on-line and off-line were increased year by year. The number of anti-sites was decreased since 2005 and the proportion of highly activated sites was lowest in 2005. On the activity of anti-sites, the number of providing the information were more than the number of presenting the complaint among the bulletin writings. The number of the bulletin writing were more in highly activated sites than in low activated sites. most of highly activated sites were problem solving type compared to the low activated sites. The number of the bulletin writings in company anti-sites were the most among three type of subject of anti-site. The number of the bulletin writings in cafe type were more than in home-page type. On the evaluation of consumers' anti-sites, most of the sites didn't update the notices and provided incomplete information how consumers participated in the protesting movements. The highly activated sites functioned better in most parts in providing a information, connection with other consumer and site manager, management of the site.

본 연구는 트랜스미디어라는 개념을 둘러싸고 난립해있는 용어의 문제를 인식하고, 언어기호학의 통합체 이론을 적용하여 개념에 대한 정리와 고찰을 시도하였다. 트랜스미디어에서 접두사 '트랜스'는 횡단과 변형, 초월을 의미한다. 트랜스미디어라는 단어 자체의 이와 같은 다의성은 트랜스미디어 개념을 횡단과 변형, 초월이라는 동사적 계열을 가진 미완의 통합체로 인식할 수 있는 단초를 제공한다. 미디어 기업, 창작자, 사용자처럼 미디어 콘텐츠 분야의 주체이자 주어가 누구냐에 따라 트랜스미디어 개념의 통합체는 트랜스미디어 프랜차이즈, 트랜스미디어 스토리텔링, 프로슈머와 같은 용어와 연결된다. 세 주체가 트랜스미디어의 담화에 참여하는 목적은 IP 활용과 스토리 세계의 확장, 작품 향유로 각각 다르다. 하지만 세 주체가 미디어를 횡단하고 변형하며 초월하는 목적에서 '반복'과 '연장', '확보'와 '연결'이라는 공통의 욕망이 발견된다. 트랜스미디어 프랜차이즈, 트랜스미디어 스토리텔링, 프로슈머와 같은 용어가 트랜스미디어 개념의 '파롤'이라면, 반복과 연장, 확보와 연결은 트랜스미디어 개념의 '랑그'이다.
