  • Since the List of Plant Diseases in Korea (DisList) was first published in 1986, the 6th edition appeared 36 years later. In 2023, the 6.1 edition, a revised and improved version of the 6th edition, was released to the public on the web free of charge. The contents of DisList increased, with the number of hosts increasing from 437 taxa to 1,420 taxa and the number of disease species increasing from 1,539 to 6,680. Among these, tree diseases are 3,586 species and their hosts include 504 taxa, providing much help to experts who need them. Meanwhile, the importance of accurate disease names continues to grow with the legalization of tree care, but many disease names are still inappropriate or misused, causing confusion. Disease names that do not follow the naming regulations are still registered, and even if the same pathogen infects hosts of the same taxa, the disease names are given differently, and there are many disease names that do not indicate the characteristics of the disease. Also, there are diseases reported without Korean names. In order to make DisList better, the review committee for disease names should establish the regulations to review and register disease names, and establish a system to review new disease names before publishing papers.

  • Financial service commission notified that fingerprint information of their documents should be deleted till 2019 to the financial industry and the public institution. Business solutions for fingerprint detection and masking in document images are introduced. In this paper, a fingerprint information masking algorithm is proposed by using the multiple LBP features to extract fingerprint's intrinsic characteristics for artificial neural network decision whether the candidate is a true fingerprint or not after segmentation of versatile fingerprint candidates from a document image. The experimental results of the proposed fingerprint masking algorithm for 3,497 document images that are saved in a financial industry show that 96.4% of fingerprint information is masked, hence this fingerprint masking algorithm can be used efficiently in real fingerprint masking tasks.

  • In order to manage the water quality in reservoir, it is necessary to understand the temporal and spatial variation of reservoirs and to classify the reservoirs. In this research, agricultural reservoirs are classified according to physical characteristics (depth, residence time, shape of the reservoir etc) and water quality using multivatriate analysis (PCA and CA). CA (Cluster Analysis) method classify reservoirs into several groups as a similarity of the reservoirs, but it is difficult to indicate a full list to the one table. In case of PCA (Principle Component Analysis) method, it has the advantage for the classification on the reservoirs depending on the water quality similarity and also it is useful to analyze the relationship between related factors through correlation analysis. However PCA is limited to classify into several groups based on the characteristics of the reservoirs and each user should be classified as randomly subjective according to the relative position of the reservoir in the figure. In conclusions, compared to conventional reservoirs classification methods, both CA and PCA methods are considered to be a classification method that describes the nature of the reservoir well, but classification results has a restriction on use, so further research will be needed to complement.

  • EU는 세계 3위의 어업생산지역임에도 불구하고 가공어류와 양식수산물에 대한 세계 최대의 소비시장을 가진 탓에 만성적인 수산물 공급부족을 겪고 있다. 이에 따라 EU는 일찍부터 제3국과의 어업협정을 통한 원양어장 진출을 적극적으로 추진해 왔다. EU의 원양어장 진출정책을 시기별로 분류하면 1세대 유형에서부터 4세대 유형으로 구분가능하다. 수역별로는 크게 유럽북부와 남부수역으로 분리되어 있으나, 어업협정 유형으로는 북유럽형, 발틱형, 북미형, 중남미형, 그리고 ACP형으로 세분화 할 수 있다. EU는 특히 대부분의 쌍무어업협정을 아프리카, 인도양, 서태평양 연안국들과 맺고 있어, 이들 국가와의 쌍무적 어업관계가 EU 원양어업정책에 있어 매우 중요하다. 최근 원양어장의 자원부족현상이 점차 심각해짐에 따라 EU 위원회는 그들의 공동어업정책 개혁안에 제3국과의 어업협력강화 방안을 수립하였다. 이는 연안국과의 어업관계를 단순입어에서 동반자적 입어관계로 발전시키는 한편, 어업 외적인 부문의 협력을 포함하는 포괄적 접근 정책을 추진하고 있다. 이러한 EU의 움직임은 단순한 어획쿼터할당에 대한 입어료지급 방식은 조업국과 연안국 간의 신뢰관계 증진에 그다지 도움이 되지 못한다는 것을 의미한다. 따라서 조업국은 연안국에 대한 자원관리기술을 지원해 주고, 자원평가에도 공동으로 참여함으로써 양국간 협력적 수산자원관리정책을 지향하도록 하여야 한다는 것을 시사하고 있다.

  • A short-term atmospheric dispersion factor (${\chi}/Q$) is an essential element for radiological dose assessment following a hypothetical accidental releases of light-water nuclear power plants. The U. S. NRC developed PAVAN program to comply with the U. S. NRC's Regulatory Guide 1.145. Meteorological data is an essential element for atmospheric dispersion, and PAVAN uses a joint frequency distribution data, which represents the occurrence probability of wind speed and wind direction for atmospheric stability. Using the meteorological data measured at Kori and Wolsung sites for the last 5 years (from 2006 to 2010), a variety of joint frequency distribution data were prepared to evaluate ${\chi}/Q$ values with different wind speed classifications (U. S. NRC's recommendation and even distribution of occurrence probability) and periods of meteorological data to be analyzed (1 year, 2 year, 3 year, 4 year, 5 year). As a result, it was found that the influence of the wind speed classification on ${\chi}/Q$ values is little, while the influence of the periods of meteorological data to be analyzed is relatively significant, representing more than 1.5 times in the ratio of maximum to minimum values.

  • Media scholars take a lion stake in power circle. Not only do they take a part in media policies but seize prestigious positions like board members in Korea Communication Commission(KCC). Unfortunately, though, little has been known about who they are, what qualifications they have, and whether they meet public interests. This paper attempts to unveil the mechanism of those politicized intellectuals who are specialized on the media. Two categories divided into 'representative' and 'expertise' are employed for this purpose. On the one hand, the representative means the degree of committment into such public services as participation in conferences or non-profit organizations. On the other hand, the number of research articles, books and projects belong to the expertise. Evaluation levels consist of 'excellence, good and average' were allocated to those scholars who are(were) in 'Power Hole,' where decision makings come into being. Some interesting observations were made though this study. First of all, such criteria as representative and expertise vaguely suggested by the laws were hardly fit into those intellectuals, Rarely did they commit into public service let alone showing vigilance in academic activities. Secondly, both ideological loyalty and political activities in line with the government had much to do with taking such positions. Thirdly, not surprisingly, it showed that to graduate from Seoul National University and have Ph.D. degree from U.S.A. was one of the most essential factors. In final, most of them were very good at taking advantage of the press in way of boosting their publicity. To attend at policy making processes either in form of board members or advisers is inevitable for media experts. However, as shown in this study, such qualification of public service and academic eagerness shouldn't be underestimated. Academic integrity not selling intelligence solely for private interests needs to be protected as well. The authors hope this study to provide a valuable opportunity to establish a kind of ethical standards in participating into politics.

  • As the proportion of sports events in the sports industry grows, the official sponsor market for sports events is also increasing. But because official sponsors are limited and expensive, some companies approach sporting events by way of Ambush marketing. This study is to analyze the differences of media exposure between official sponsors and general companies of mega sport events. To accomplish the purpose of the study, we collected text articles and analyzed them from the period of 2016 Rio Olympics, one year before the Olympics and one year after the Olympics. Web crawling was performed using Python for the collection of articles. Morphological and frequency analysis was performed using the KoNLP package and the TM package of statistical program R. In addition, the opinions of the related experts group were gathered to classify the companies or organizations in the media as the Organizing Committees for the Olympic Games(OCOGs), official sponsor, and general companies. As a result of the analysis, 5,220 times appeared related to the OCOGs, 7,845 times appeared related to the official sponsor, and 7,028 times appeared related to general companies. There isn't much difference in the frequency of exposure between official sponsors and general companies. It implies that Ambush marketing is recognized as a strategic marketing technique. The International Olympic Committee(IOC) has to recognize these social phenomena and establish reasonable standards for the marketing activities of official sponsors and general companies. And this study will serve as a basis for fair sponsor activities or marketing activities of sports events.

  • The differentiation between malignancy-related ascites(MRA) and non-malignant ascites (NMA) is important for further diagnostic and therapeutic purposes. Although many parameters were investigated, none has provided a complete distinction between MRA and NMA. We investigated several ascitic fluid parameters to determine the differential power, and to differentiate malignant-related from nonmalignant-related ascites with a sequence of sensitive parameters followed by specific parameters. For the present study, 80 patients with ascites were divided into two groups: MRA and NMA, The MRA group was consisted of 27 patients with proven malignancy by image study, biopsy, and follow up: 21 of these patients had peritoneal carcinomatosis, but the remaining 6 showed no evidence of peritoneal carcinomatosis. The NMA group was consisted of 53 patients with no evidence of malignancy: among these patients, one had SLE, and others had liver cirrhosis, The samples of blood and ascites were obtained simultaneously, and then the levels of ascites cholesterol, CEA. protein and LDH, cytology, albumin gradient, ascites/serum concen-tration ratios of LDH(LDH A/S), and ascites/serum concentration ratios of protein(protein A/S) were measured. Applying cut-off limits for determined parameters, we estimated the diagnostic efficacy of each parameter, Among the eight parameters investigated, ascites fluid cholesterol yielded the best sensitive value of 93%(cut-off value 30mg/dl), and cytologic examination and the protein A/S(cut-off value 0.5) showed the most specific value of 100% and 96%, respectively. Based on the above results, the diagnostic sequence with cholesterol as a sensitive parameter followed by the combination of cytologic examination and protein A/S as specific parameters, was tested in 80 patients. This diagnostic sequence identified 81.5% of patients with malignancy, and all patients with peritoneal carcinomatosis were classified as malignancy-related ascites. In spite of many limitations, this proposed diagnostic sequence may permit a cost-effective and simple differentiation of malignancy-related ascites from nonmalignant ascites.

  • In 1814, Giovanni Battista Monteggia first described two cases of fracture of proximal third of ulna with a dislocation of radial head, and this combined injury is now known as the Monteggia fracture. Despite its rarity, the importance of early recognition of dislocated radial head and correct treatment bas been emphasized. Eight cases of Monteggia fracture were studied from March, 1984 to June, 1987. The results are as follows 1. Male patients were six and female were two. 2. The frequent cause of injury was fall down in four cases. 3. Bado type I accounted for 50%, type II for 12.5% and type III for 37.5%. 4. The level of ulna fracture was above upper one third of ulna in seven. 5. The common direction of dislocated radial head was anterior. 6. Two children and two adults were managed by closed reduction. Four ulna fractures in adult were treated by open reduction and internal fixation using a semitubular plate. 7. The results (by Bruce et al. criteria) were 3 excellent, 2 good, 1 fair and 2 poor.
