The handwriting based person identification systems use their designer's perceived structural properties of handwriting as features. In this paper, we present a system that uses those structural properties as features that graphologists and expert handwriting analyzers use for determining the writer's personality traits and for making other assessments. The advantage of these features is that their definition is based on sound historical knowledge (i.e., the knowledge discovered by graphologists, psychiatrists, forensic experts, and experts of other domains in analyzing the relationships between handwritten stroke characteristics and the phenomena that imbeds individuality in stroke). Hence, each stroke characteristic reflects a personality trait. We have measured the effectiveness of these features on a subset of handwritten Devnagari and Latin script datasets from the Center for Pattern Analysis and Recognition (CPAR-2012), which were written by 100 people where each person wrote three samples of the Devnagari and Latin text that we have designed for our experiments. The experiment yielded 100% correct identification on the training set. However, we observed an 88% and 89% correct identification rate when we experimented with 200 training samples and 100 test samples on handwritten Devnagari and Latin text. By introducing the majority voting based rejection criteria, the identification accuracy increased to 97% on both script sets.

The objective of this study was to develop a system for handwriting recognition in three dimensions (3D) to authenticate users. While previous studies have used a stylus pen for two-dimensional input on a tablet, this study uses the Wii Remote controller because it can capture 3D human motion and could therefore be more effective means of recognition. The information obtained from a Wii Remote controller included x and y coordinates, acceleration (x, y, z), angular velocity (pitch, yaw, roll), twelve input buttons, and time. The proposed system calculates distances using six features extracted after preprocessing the data. In an experiment where 15 subjects wrote "AIZU" 10 times, we obtained a 94.8% identification rate using a combination of writing velocity, the peak value of pitch, and the peak value of yaw. This suggests that this system holds promise for handwriting-based authentication in the future.

In this paper, we present a comparative study of spatial domain features for writer identification and verification with different ink width conditions. The existing methods give high error rates, when comparing two handwritten images with different pen types. To the best of our knowledge, we are the first to design the feature with different ink width conditions. To address this problem, contour based features were extracted using a chain code method. To improve accuracy at higher levels, we considered histograms of chain code and variance in bins of histogram of chain code as features to discriminate handwriting samples. The system was trained and tested for 1,000 writers with two samples using different writing instruments. The feature performance is tested on our newly created dataset of 4,000 samples. The experimental results show that the histogram of chain code feature is good compared to other methods with false acceptance rate of 11.67%, false rejection rate of 36.70%, average error rates of 24.18%, and average verification accuracy of 75.89% on our new dataset. We also studied the effect of amount of text and dataset size on verification accuracy.

Seriously depressed by the failure in the first performance of his own drama ${\ll}$The Government Inspector${\gg}$, N. Gogol sought out a space, Italy, which is obviously a turning point for the writer. Here in Italy, the writer could be able to explore an essential foundation for the national identity as well as self-identification of Russian traditional culture, all of which have already been epitomized in the Renaissance period in Italy. The city Rome itself provided Gogol with its grandness and harmonious perfectness, influencing something 'spiritual being' upon the writer. The work under discussion, "Rome," is thus created through these literary circumstances. Though it is made under the different title as "Annuntiata" and it delivers a love story between lovers, the story lines gradually turned into a fiction about the city, Rome. In comparison with city Paris, Gogol himself presents a negative view of the French metropolitan, saying that it is nothing but a by-product of the 19th century civilization. Interestingly enough, Rome for Gogol is totally different; it is the place of sublimity, that is a locus of harmonious, holy, and eternal city. Likewise, this pattern can be said of another description on the two contradictory cities: Paris and Rome. Again, Gogol fully pictures the city Paris as centripetal and Rome as centrifugal, in which the main protagonist makes the reader indulge in his own world. Throughout the story the writer tells us a transformation experienced by his character, and the work ends with an open denouement. Like Jerusalem, Rome is the city of resurrection for Gogol. Yet, this kind of possibility of transformation in the story is exposed to the hero, and it arguably depends on the extent to which he explores the readiness for encountering of 'eternity' in this "eternal city."

전통시대의 문학을 생태주의적 관점에서 논의한다면 당대 지식인인 양반들과 사대부의 시조인 평시조에 나타난 자연관 정도로 생각하였던 탓에 사설시조나 서민작가는 큰 관심의 대상이 아니었다. 또한 사설시조 속의 '산것들'도 주목받지 못했다. 그것들은 시어로서는 부적절한, 이른바, '생경한 시어' 또는 '비시적 사물의 시화'라는 홀대를 받았다. 그 어떤 평자들도 그 살아 숨쉬는 것들을 '산것들'로 인식하지 않았고, 따라서 작품속의 주체적 대상으로도 인식하고자 하지 않았다. 그러나 사설시조에서는 경험적, 구체적, 일상적 동물들의 등장이 관심을 끈다. 이는 사실 양반들의 관념적 생물관과 비교될 만한 단서도 된다. 본고는 사설시조 속의 이들 '산것들'과 그들에 대한 작가의 시각과 인식에 대해 소박한 논의를 하였다. 본고에서 '산것들'은 살아 움직이는 것들을 의미한다. 먼저 사설시조 속의 '산것들'은 일상과 경험의 생물들이었다. 그것들은 더 이상 사설시조의 작가에게는 지식이나 관념적 생물이 아니었다. 생물환경적으로 도저히 공생할 수 없는 '산것들'이 함께 등장하는 것이 가능하거나 그 반대로 오랫동안 친숙한 일상경험에 근거하여 '산것들'에 대한 경험적 인식이 탁월한 작품도 있었다. 또한 '산것들'에 대한 사설시조 작가들의 친근하고도 애틋한, 그리고 우리 인간과 다를 바 없는 생명체에 대한 온기 있는 시선은 때로는 동일시의 대상으로 또 때로는 감정이입의 대상으로 파악하기도 하였다. 더러는 애증이 혼재하는 복합적 시선도 눈에 띈다. 사설시조 작가들의 삶은 온갖 '산것들'과 함께 하는 공생의 삶에 다름 아니다.

This essay examines the first-generation Korean American writer, No-Yong Park's falsehoods about his ethnic identity to suggest how and why he passed for Chinese, and to explore the political, anti-Japanese implications of these actions. The essay first identifies erroneous information circulating about his biographical background, presents some other materials that help us better understand the context in which he forged his Chinese identity, and then examines how he represented himself as Chinese in his published works. I would argue that Park's self-identification as Chinese was a resulting outcome of his naturalization caused by the Japanese colonial power in Korea and also one of his surviving strategies in the racist environment within American society. Looking at some of his works-including Making a New China (1929), An Oriental View of American Civilization (1934), Chinaman's Chance: Autobiography (1940)-and examining how he represented Korea and its people reveal how he tried to raise voice for them. By doing so, this essay illuminates Park's resistance to Japan's colonial discourse and power in Korea while revealing his lifetime passing as Chinese-far from his refusal to belong to the Korean community, or to acknowledge being Korean.

Epigenetic writers including DNA and histone lysine methyltransferases (DNMT and HKMT, respectively) play an initiative role in the differentiation and development of eukaryotic organisms through the spatiotemporal regulation of functional gene expressions. However, the epigenetic mechanisms have long been suspected in helminth parasites lacking the major DNA methyltransferases DNMT1 and DNMT3a/3b. Very little information on the evolutionary status of the epigenetic tools and their role in regulating chromosomal genes is currently available in the parasitic trematodes. We previously suggested the probable role of a DNMT2-like protein (CsDNMT2) as a genuine epigenetic writer in a trematode parasite Clonorchis sinensis. Here, we analyzed the phylogeny of HKMT subfamily members in the liver fluke and other platyhelminth species. The platyhelminth genomes examined conserved genes for the most of SET domain-containing HKMT and Disruptor of Telomeric Silencing 1 subfamilies, while some genes were expanded specifically in certain platyhelminth genomes. Related to the high gene dosages for HKMT activities covering differential but somewhat overlapping substrate specificities, variously methylated histones were recognized throughout the tissues/organs of C. sinensis adults. The temporal expressions of genes involved in eggshell formation were gradually decreased to their lowest levels proportionally to aging, whereas those of some epigenetic tool genes were re-boosted in the later adult stages of the parasite. Furthermore, these expression levels were significantly affected by treatment with DNMT and HKMT inhibitors. Our data strongly suggest that methylated histones are potent epigenetic markers that modulate the spatiotemporal expressions of C. sinensis genes, especially those involved in sexual reproduction.

근대교육기(1876${\sim}$1910) 중 1905년부터 1910년 사이는 우리 나라 교육에 대한 일제의 간섭이 가장 극심했던 시기였다. 이에 대응하여 우리 민족은 전국 단위나 지방 단위로 학회를 세웠고, 학회를 통하여 근대 교육을 실천하려는 의지를 보였다. 이 연구에서는 근대교육기에 국내에서 출판된 학회지 9종 132권을 분석하여 다음과 같은 결론을 얻었다. 첫째, 근대교육기에 발간된 학회지의 주요 내용은 민족의 정체성을 확립하기 위한 역사나 지리 등의 내용과 계몽적인 차원에서 서구의 정치나 경제 체제를 소개하는 글과 더불어 자연과학에 관한 논술도 상당한 비중을 차지했다는 점이다. 둘째, 과학 관련 논술을 분야별로 분석해보면 생리${\cdot}$ 위생을 포함한 생물학 분야와 지구과학 분야가 비교적 많았다. 반면에 물리학이나 화학 분야는 아주 적었다는 특징이 나타난다. 셋째, 학회지에 게재된 지구과학 관련 논술만 분석하더라도, 대부분 같은 저자에 의해 교과서적인 기초 내용을 연재한 논술이 많이 보인다. 이러한 의미에서 학술지에 게재된 과학 관련 논술은 근대 교육기에 우리 나름의 과학 교육을 확립하기 위한 노력으로 평가된다.

The purpose of this study was to evaluate the educatconal function of the health related articles. The health articles of the four major daily newspapers from Jan. 1st, 1980 to Dec. 31th, 1984 were used and examined for the study. Editorials were excluded. The major results were summarized as follows: 1. The total number of the health articles subjected to the study in the four major daily newspapers was 4,431. On the whole, the health articles were appeared most frequently in 1981. As for monthly distribution, the health articles were appeared most frequently on June.(9.3%). As for weekly distribution, the health articles were appeared most frequently on wednesday and saturday(50.8%). As for the subjects of content; the health articles related to the health & disease management were appeared most frequently(52.8%), but the health articles on industrial health were showed least frequently(0.6%). 2. Reviewing the chronological trend of the health articles, the frequency of appearance of the public health administration was tended to increase year by year, whereas that of enviornmental health, industrial health and population decrease relatively. As for appealing method, it was observed that the articles providing health information were steadily increasing. As for the motives of writing the health articles, there was a tendency that seasonal motive, symphosium & seminar and compaign were increasing, but motive of legislative action and administrative action were gradually decreasing. As for type of the health articles, it was observed that interpretation and research result were steadily increasing. As for the writer of the health articles, there was a tendency that writing by reporter was increasing, whereas writing by experts was decreasing. As for tone of head, the health articles written by identification statement was tended to increase. As for the appearance of photograph & cut, it was observed that the health articles excluding photograph & cut were increasing. 3. When contents were analyzed by subjects, for the purpose of providing information was used most frequently as appealing method for all subjects. As for the motive of writing, "from the interest of writers" was most frequent. As for the type of articles, interpretation type was most prevalent for the public health administration, enviornmental health, food hygrene & nutrition, population and health behavior, while contribution by experts was most frequent for the health & disease management. As for the size of articles, all subjects except the population were appeared most frequently on the column. size between 100㎠ and 199㎠.

언어는 정보교환이라는 사회적 기능을 가지고 있다. 60년대 이래로 언어학자들의 관심이 언어의 정보전달 기능, 즉 어떠한 의미가 어떤 형식을 통하여 어떻게 전달되는가 하는, 의미, 형식, 기능의 관계에 점차 집중되게 되었다. 이러한 관계는 문장분석보다는 담화분석을 통하여 더욱 명백하게 파악된다. 본 연구는 한국 설화문에서 사용되는 화제표현의 방법과 표현된 화제의 연속성을 측정함으로 효율적인 정보교환의 방법을 살펴보았다. 분석된 문법구조들은 영대용, 인칭대명사, 지시대명사, 고유대명사, 지시사 뒤에 오는 명사, 소유격을 따르는 명사, 한정적 명사 그리고 비한정적 명사, 모두 8가지이다. 본 연구의 결과를 다음과 같이 요약할수 있다. 첫째, 한국 설화문에서 '인간임'(humanness)이 가장 강한 화제의 연속성을 나타낸다. 인간지시 논항들은 주로 행위자 또는 경엄자를 나타내기 때문에 절이난 담화의 화제역학을 한다. 둘째, 이들 문법구조들은 각기 다른 화제표현의 연속성 정도를 나타낸다. 연속성 정도가 높은 구조일수록 표현이 간단하며, 연속성의 정도가 낮을수록 표현이 복잡하다. 셋째, 화제표현의 연속성은 구조들의 통사적 특성 이외에 사회적문화적 요인들과 작가의 화용상의 목적 등에 좌우되기도 한다. 마지막으로, 실질적인 정보교환의 방법을 파악하기 위하여, 구어체와 문어체 담화문을 비교분석하여 화제표현의 효율적 방법을 고찰할 것을 제의한다.
