  • The present study examines the characteristics of the international literature of classification systems published in the period 1981-1990. The references in the 'Classification Literature' sections of International Classification and the references in these source items were examined. The present study focused on analyzing each of the following characteristics: format, subject, language, geographical origin, age, authorship and number of references. The findings from the data analyses show clearly that in the literature of classification systems, I) books were the most frequently cited format; 2) library and information science was the most frequently cited subject; 3) English was the major language; 4) the literature of each classification system was written predominently in English except for Library Bibliographic Classification; 5) the language of each source item was the same as that of the greatest number of references of that source item: 6) the U.S., Germany, India, Russia, and the U.K. were the major geographic origin of publication; 7) there was a very close relationship between country of publication and language: 8) the country of origin of the documents was cited more than any other country except for the U.S.: 9) Price's Index of the literature revealed that the literature was a soft science and the half-life of the literature was about 7.5 years; 10) there was a preponderance of single authorships; 11) the literature was not a scholarly or scientific literature, according to the average number of references in source items and the percentage of unreferenced items. The findings of this reference study provide a better understanding of the characteristics of the classification systems literature. They prove useful for the collection development and assist classification systems researchers to prepare linguistically for their careers and encourage international communication efforts.

  • Background: The coronavirus problem is an ecological problem stemming from a sudden change in the relationship between parasites and hosts. Ecologists judge organisms that are established out of their original territory as exotic species. Unlike in their original habitat, these exotic species become very aggressive in their newly settled habitat. Coronavirus infection damage was bigger in Europe or the United States than that in the country of its origin, China, and its neighboring countries. Therefore, coronavirus infection damage resembles the damage due to the invasive species. Results: Exotic species are found in places with similar environmental conditions to those of their origin when introduced to other ecological regions. However, there are few ecological ill effects in their place of origin, while the damage is usually severe in the ecological regions in which it is introduced. According to historical records, exotic infectious diseases, such as European smallpox and measles, also showed a similar trend and caused great damage in newly established places. Therefore, it is expected that measures to manage exotic species could be used for the prevention of exotic infectious diseases such as the coronavirus. Conclusions: Prevention comes first in the management of exotic species, and in order to come up with preventive measures, it is important to collect information on the characteristics of related organisms and their preferred environment. In this respect, ecosystem management measures such as exotic species management measures could be used as a reference to prevent and suppress the spread. To put these measures into practice, it is urgently required to establish an international integrated information network for collecting and exchanging information between regions and countries. Furthermore, a systematic ecosystem-management strategy in which natural and human environments could continue sustainable lives in their respective locations may serve as a countermeasure to prevent infectious diseases.

  • Origin authenticity of the animals used as food has always been a major concern to consumers around the world. In the past twenty years, a stable isotope ratio has been used for origin authentication. In this study, pork samples, both local and imported, were collected from the major markets from all around South Korea and analyzed for stable isotope ratios of nitrogen (${\delta}^{15}N$‰) and carbon (${\delta}^{13}C$‰), using Isotope Ratio Mass Spectrometry (IR-MS). A total of 599 samples with 335 Korean and 264 imported from 13 countries within America and Europe were investigated in accordance to the standard established methods for isotope ratio analysis. The results showed a significant variation related to the origin of the samples, explaining the difference in the feeding styles of the pork in each country. The stable isotope ratio values of carbon (${\delta}^{13}C$‰) were found in the decreasing order of: America ($-15.55{\pm}1.01$‰)>Korea ($-19.62{\pm}0.89$‰)>Europe ($-24.79{\pm}1.35$‰). Canada was having ${\delta}^{13}C$ ratio of $-22.87{\pm}0.92$‰, which is very low in the region of America and very close to Europe (-23.78 to -27.17‰). For nitrogen ${\delta}^{15}N$‰ the order was: America ($4.92{\pm}0.71$‰)>Europe ($4.54{\pm}0.66$‰)>Korea ($3.69{\pm}0.54$‰), with a slight variation among countries in each region studied. From the results it was concluded that the stable isotope ratio of the pork samples from different countries provide enough information about the origin and is therefore a potential tool which can be employed for origin authentication.

  • 고세균 (Archaea)의 보존적 유전자를 파악하고 각 분류 단계별로 추가되는 보존적 유전자를 밝히기 위해 그리고 해양성 Euryarchaeota와 육지성 Euryarchaeota의 유전자 조성을 비교하기위해 COG (clusters of orthologous groups of proteins) 알고리즘을 이용하였다. 총 9종의 고세균이 공통적으로 보유하는 보존적 유전자는 340개로 나타났고 8종의 Euryarchaeota는 388개의 유전자가 보존적이었다. Euryarchaeota 각 종이 보유하는 orthologous에 대한 보존적 유전자의 비율은 20.73∼31.54%로 나타났다. 세균과 S.cerevisiae에는 없고 고세균 수준에서만 공통적인 265개 COG의 조성은 유전정보의 보존과 처리에 관여하는 COG가 94개 (35.5%)이고 대사에 관여하는 COG가 82개 (30.9%)로 유전정보와 물질대사와 관여하는 COG의 보존성이 높은 것으로 나타나 고세균이 독특한 생명체계를 이루고 있는 것으로 사료되었다. Euryarchaeota를 Crenarchaeota와 비교하면 핵산대사에서는 상당한 차이를 보이며 유전정보의 저장과 처리에서는 큰 차이가 없는 것으로 판단되었다. 해양성 Euryarchaeota의 보존적 COG는 기능분류별 종류가 육지성 Euryarchaeota와 달랐고 물질대사 관련 COG의 경우 육지성이 해양성보다 다양한 것을 알 수 있었다. 그리고 육지성과 해양성 Euryarchaeota는 탄수화물대사 등을 비롯한 생리적 측면에서 서로 차이가 있을 가능성이 높을 것으로 사료되었다. 본 연구는 해양 극한미생물인 해양성 Euryarchaeota의 기원과 분류단계에 따른 보존적 유전자를 파악하는데 도움을 줄뿐만 아니라 향후 해양미생물 등의 유용유전자 탐색 등에서도 Manco (Arch. Biochem. Biophy. 373, 182 (2000)) 등의 보고와 같이 충분한 연구가치가 있는 것으로 사료되었다.

  • 인터넷을 통한 기업 활동을 방해하는 악의적인 총격 형태 중 최근 가장 빈번하게 그리고 큰 피해를 주는 공격 형태가 Dos(Denial-of-service) 공격이다. Dos 공격은 공격자가 자신의 위치를 숨기기 위하여 자신의 IP를 속이는 IP 스푸핑(spoofing) 을 하기 때문에 피해 시스템에서 받아들인 패킷의 소스 IP 주소를 가지고는 공격자의 정화한 위치를 파악한 수가 없게 된다. 또한 공격에 대응하여 방어한다고 해도 공격 진원지를 찾아내지 못한다면 추후 동일한 공격자에 의해 재차 공격을 받을 가능성을 배제할 수 없는 실정이다. 이에 본 논문은 DoS 총격에 대응하는 하나의 방법으로 마킹 알고리듬을 이용하여 공격 경로를 찾아내고, 더 나아가 공격 진원지의 MAC 주소를 알아냄으로써 공격 진원지를 찾아내는 방법을 제안한다. 또한 마킹 알고리듬에서의 패킷 도착율을 향상시키는 기법을 제안하여 좀더 빠른 시갈 내에 공격위치의 탐지를 가능하게 함으로써 DoS 공격에 대한 적절한 대응과 공격자를 찾아내는 좀 더 향상된 성능을 보인다.

  • 이동 정보에 대한 분석은 다양한 사회문제 해결에 도움이 될 수 있으며, 이러한 이동 정보를 정량화하여 나타낸 대표적인 데이터 중 하나가 Origin-Destination(OD) 데이터이다. 기존 연구들에서는 OD 데이터에 시각화 방법론을 도입했으나, 이러한 시각화 도구를 실제 사회 문제 해결에 사용하여 사용성을 평가한 적은 없다. 본 연구에서는 사회 문제해결에 용이한 시각화 도구(이하 SeoulOD-Vis)를 3가지 모듈(지도 시각화, 조건 선택, 세부 정보 표기)에 기반해 개발하였다. 그리고 28명의 피험자를 대상으로 SeoulOD-Vis와 동일한 OD 데이터를 기반으로 제작된 공개된 시각화 도구(기존 시각화 도구)의 사용성을 비교하였다. 그 결과, SeoulOD-Vis 가 기존 시각화 도구보다 높은 사용성 및 문제 수행 성능을 보였으며, 이는 SeoulOD-Vis에 포함된 '조건 선택' 및 '세부 정보 표기' 모듈에 기인했다. 또한, '지도 시각화' 모듈에서 제공하는 히트맵 및 플로우맵은 각기 다른 목적으로 사용되며 다양한 사회 문제 해결에 도움을 줄 수 있음을 확인했다. 본 연구의 결과는 추후 이동 정보를 활용한 사회 문제 해결을 위한 시각화 도구 개발 및 이를 통한 다양한 사회 문제 해결에 기여할 수 있을 것으로 기대된다.

  • Yunnan, where twenty-six minor ethnics live, is located in Southwest part of China. They have preserved and developed their folk costume, artcraft, music and dance in their peculiar way with natural and cultural surroundings. So, Yunnan is known as a living folk museum. It's worth examining how climate and circumstances change has affected certain differences of dress shape in same ethnic. Research into costumes of minor ethnics can contribute to the study of origin of the trousers, as this group of people have well succeeded the basic form of trousers through their cultural history and everyday life. This study, at first, investigates geographical surroundings of each minor ethnic group, and figures out the style of all trousers by measuring the each size, then compares design color pattern and fabric. The origin of trousers examined by formative characteristics has been classified and comparatively studied. The study materials are twenty-three trousers selected from in Yunnan Folk Museum as well as other relevant literature records. This study suggests that one can examine the type of human culture through the forms of costume which reflects folk custom geography economy etc. This, in turn, can be used as a basic information for other studies, and in particular, for the study of origin and structure of the trousers.

  • The marketing environment has become competitive to an extent that requires firms to target their products at markets that span national boundaries. However, competitive clout cannot be achieved in global consumer markets unless firms thoroughly understand and adequately respond to the core values and needs of those consumers. Brand equity is one of the most important assets to a company. Especially in sportswear markets, brand equity is the crucial value added to a product by its brand name. Factors such as country of origin also influence customer's attitude towards brand equity. Therefore, this paper discusses the relationship between country of origin effect and brand equity, and how they influence consumers' loyalty for respective brands. This paper focused on the sports shoes market, because it is an increasing area of opportunity for world manufacturers. The objectives of this study were the following. (1) Test the effect of country of origin on brand equity. (2) Test how brand equity influences consumers' brand loyalty. (3) Find whether there are differences in the effects of country of origin and brand equity among the three countries. (4) Find whether there are differences in the effects of country of origin and brand equity among the different lifestyles. Based on the review of literature results, the hypotheses are concluded as the following: H1-a: Country image has positive influence on country of origin. H1-b: Product perception has positive influence on country of origin. H2-a: Perceived quality has positive effect on brand equity. H2-b: Perceived price has positive effect on brand equity. H3: Country of origin has positive effect on brand equity. H4: Brand equity has a positive impact on brand loyalty. Research model was constructed (see Fig. 1). After data analysis, the following results were concluded: sports shoes purchase behavior showed significant differences among Korean, Chinese, and American consumers for favorite brand, purchased brand, purchased place, information usage, and favorite sports games. The results of this study also extend the research of the relationship among country of origin, brand equity and brand loyalty to the sports shoes market. Brand equity was proven to have a significant relationship with brand loyalty for all countries. The factors which can influence brand equity are different for different countries. The third finding of this paper is that we identified different three lifestyles, adventurer, follower, and laggard, for Korean, Chinese and American consumers. Without the nationality boundary, seeing the emergence of a new group of consumers who have similar preferences and buy similar brands is more important. All of the consumers consider brand equity to keep their brand loyalty. Perceived price is the only factor which can influence brand equity for adventurers; brand is more important for them. The laggards were not influenced by any factor. All of the factors expect perceived price are important for the followers. Marketing managers should consider brand equity when introducing their brand into a new market. Also localization is the basic strategy that all the sports shoes companies should understand. But as a global brand, understanding the same characteristics for each country is more important to build global strategy.
