  • 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.

  • 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.

  • In this paper, it was presented a design on the dynamic multimedia fingerprinting code for anti-collusion code(ACC) in the protection of multimedia content. Multimedia fingerprinting code for the conventional ACC, is designed with a mathematical method to increase k to k+1 by transform from BIBD's an incidence matrix to a complement matrix. A codevector of the complement matrix is allowanced fingerprinting code to a user' authority and embedded into a content. In the proposed algorithm, the feature points were drawing from a content which user bought, with based on these to design the dynamical multimedia fingerprinting code. The candidate codes of ACC which satisfied BIBD's v and k+1 condition is registered in the codebook, and then a matrix is generated(Below that it calls "Rhee matrix") with ${\lambda}+1$ condition. In the experimental results, the codevector of Rhee matrix based on a feature point of the content is generated to exist k in the confidence interval at the significance level ($1-{\alpha}$). Euclidean distances between row and row and column and column each other of Rhee matrix is working out same k value as like the compliment matrices based on BIBD and Graph. Moreover, first row and column of Rhee matrix are an initial firing vector and to be a forensic mark of content protection. Because of the connection of the rest codevectors is reported in the codebook, when trace a colluded code, it isn't necessity to solve a correlation coefficient between original fingerprinting code and the colluded code but only search the codebook then a trace of the colluder is easy. Thus, the generated Rhee matrix in this paper has an excellent robustness and fidelity more than the mathematically generated matrix based on BIBD as ACC.

  • 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.

  • Annually, electrical fires caused by arcing phenomena in power system rapidly increase as the use of more electric appliances, but there is no established method for the prevention of the accidents. With this background, this paper dealt with the experimental results on a series arc detection technique and a device for air conditioners. Series arcing phenomena that is generated in incomplete connection of air conditioners was simulated, and the frequency spectrum was analyzed. The Fast Fourier Transform (FFT) of the arc pulse showed that the dominant frequency components exist in ranges of 190 kHz~250 kHz and 900 kHz~1.6 MHz. An arc detection circuit with low cut off frequency of 170 kHz to attenuate 60 Hz by 170 dB and a signal discriminator were designed. Also, an algorithm which separate series arc signal from unwanted noises produced by switching operation, inverter, and surge was proposed. Application experiment was carried out on several types of air-conditioners by using the arc generator specified in UL1699, and the results showed the over 99 % accuracy.

  • 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.

  • This study recognizes the problem of terminology surrounding the concept of transmedia and attempts to arrange and examine the concept by applying the syntagmes theory of linguistics. In transmedia, the prefix 'trans' means transversal, transformation, and transcendence. This versatility of the word transmedia itself provides a starting point for recognizing the concept of transmedia as an incomplete syntagmes with the verbal paradigm of transversal, transformation and transcendence. Depending on who is the subject of media content, such as media companies, creators, and users, syntagmes of transmedia is linked to terms such as transmedia franchise, transmedia storytelling, and prosumer. The purposes of the three subjects in the discourse of transmedia are different, using IP, expanding the story world, and enjoying the work. However, the common desires of 'repeat', 'extension', 'secure' and 'connection' are found in the purpose of three subjects. If terms like transmedia franchise, transmedia storytelling, and prosumer are 'parols' of the transmedia concept, then repetition, extension, securing and linking are the 'langues' of the transmedia concept.
