The epidemiological study was performed to survey the prevalence of fish pathogens of cultured olive flounder, Paralichthys olivaceus collected in Pohang, Ulsan.Gijang, Keoje and Wando area of Korea from 2005 to 2007. In this study, the fish pathogens were detected from 1,528 among 2,238 fish samples and annual incidences were 60.6% in 2005, 66.7% in 2006 and 72.3% in 2007, respectively. Seasonal prevalence was 63.5% in February, 67.3% in May, 75.1% in August and 64.2% in November for three years. The detection rates of parasites, bacteria or viruses were 36.7%, 32.8% and 31.4%, respectively. 775 cases (34.6%) among 2,238 fish samples showed mixed infection with a different pathogens. The distribution of specific diseases showed that detection rates of diseases occurring the most frequently during the study period were Trichodina spp., (28.2%), viral nervous necrosis virus (24.3%), Vibrio (11.6%), viral hemorrhagic septicaemia virus (10.5%).

In the Vinous-throated Parrotbill Paradoxornis webbianus, potential intraspecific nest parasitism was observed in four nests (0.38%, n=1,062) during twelve breeding seasons between 1988 and 2007. At first, a nest involved 9 white eggs was found in Puyong-ri, Yangpyong-gun, Kyonggi Province in 1995. This nest would be parasitized by the same species, given that this is out of range of normal clutch size (5 eggs) in Vinous-throated Parrotbills. The second and third cases were recorded in 2001 and 2005 in Sa-dong, Ansan City, Kyonggi Province, respectively. In these nests, two eggs were added to the clutch in a single day. The final observation was made in Puyong-ri in 2007, in which one white egg was laid in the nest at the pre-laying stage. The color of the egg was different from that of the original clutch (blue). The above four things suggest that intraspecific nest parasitism can occur in Vinous-throated Parrotbills although it is an uncommon phenomenon in their life history.

This study was examined to identify the race differentiation and distribution of mating type on Phytophthora capsici population in Korea. One hundred forty three isolates of P. capsici were collected from several locations of Korea in 2005-2007. In 2005, 20 isolates of P. capsici were collected and surveyed as A1 mating type of 75% and A2 mating type of 25%. In 2006, a total of 91 isolates were collected and separated as A1 mating type of 49.0%, A2 mating type of 42.9% and S type (sterile) of 3.3%. Isolates obtained in 2007 were similar to 2006 results. Totally, ratio of mating type of 153 isolates was confirmed that A1 type was 56.6%, A2 type was 39.2%, and S type was 4.2%. Thirteen pepper cultivars with different pathogenic response to 3 typical isolates having different mating were screened among 50 pepper cultivars and determined as race differential cultivars for investigation. The 11 races of P. capsici were found by using 13-race differential cultivars. These results indicated that at least 11 races of P. capsici are existed and confirmed race differentiation of P. capsici in pepper.

In Korea, isolated cultivation has been implemented for 102 genera, including about 250 species, each of which has underwent microscopic inspection, cultivation of bacteria in selective medium, analysis of physiology and biochemistry, enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR). The number of isolated microorganisms was 8,307 in the period of 2005-2012, and bulbs and tubers had the greatest diversity of microorganisms, of 5,165 (62.2%), followed by 2,119 (25.0%) sapling, 796 (9.6%) seed, 150 (1.8%) cutting slip, 70 (0.8%) branch graft and 7 (0.1%). The number of cases which were disqualified were 413 (4.97%), after the detection of 47 disease causing species of microorganism. Viruses predominated, with 27 species, followed by 16 fungi, a viroid, a Chromalveolata and 2 further species. Top on the list of detection was Arabis mosaic virus (77 cases), followed by Tobacco rattle virus (70 cases), Lily symptomless virus (46 cases) and Penicillium expansum (46 cases).

'Heukisul' (3x) a cross made in 2000 between 'Kyoho' (4x, Vitis sp.) and 'Thompson Seedless' (2x, Vitis vinifera L.) in a seedless grape breeding program, was preliminarily selected in 2004. After regional adaptation testing under the name of 'KTS014' at two sites during 2004-2005, it was finally selected in 2006. 'Heukisul' showed low incidence of berry shattering, resulting in a good berry set compared to 'King Dela'. 'Heukisul' had budburst on April 23, flowering on in June 9, and fruit maturation in September 29 (almost the same as 'King Dela' at Chuncheon), and it was considered a midseason cultivar. The mean berry weight was 4.0 g, about 0.7 g heavier than 'King Dela', and mean soluble solids were $21.9\;^{\circ}Brix$, about $2.7\;^{\circ}Brix$ higher than 'King Dela'. The skin color was dark violet with abundant bloom and the flesh was very firm. Although the cluster was compact, it required no cluster thinning. Also the incidence of berry cracking was very low.

This study is aimed at investigating if there were the differences on citing behavior of researchers among different fields of engineering, in terms of five items, such as types of resources cited, the average number of documents cited, the demand of current documents, languages used in cited documents, and the life decrease phenomena of information. 29,160 cited references in 2,333 articles from 4 major selected journals, published in the year of 1999, 2001, and 2003 were analyzed. The result of this study shows that there were the differences on citing behavior of researchers among different fields of engineering on all 5 items. And also, some suggestions were given the priority of library collection and shelf arrangement for the library.

The purpose of study was to analyze the trends of 2005 to 2018 revised 'convergence technology research' through text network analysis using NetMiner4.0 program. Data analysis was conducted by using keyword analysis, centrality analysis of 653 authors' keyword from 177 journals. The results of the study are as follows. First, Research on Converging Technology has been studied steadily over the past 13 years in Department of Industry Convergence. Second, the results of the search term frequency analysis show that the 'convergence technology', 'technology convergence', 'convergence', 'design', 'convergence education', 'STEAM', 'convergence research' were used as the main keywords of convergence technology research. Third, Community analysis results show that five communities have been classified five categories according to the characteristics of the search terms 'only IT', 'Cultural industry utilizing Convergence contents', 'Technology innovation and research analysis' And patent development'. Based on these results, we proposed the future directions of convergence technology research.

Zeiss사에 의해 고안되어 제작된 최초의 근대식 천체투영기(Planetarium)는 1923년 독일박물관에 설치되었다. 세계 최초의 천체투영관은 큰 이목을 끌었고, 이 소식은 전세계로 전해져 유럽의 퍼지기 시작했고 1930년대에는 미국의 갑부들이 자기 도시에 천체투영관을 설립하였다. 우리나라는 재일동포 사업가 이현수에게 일본 GOTO사의 천체투영기를 기증받아 1967년 4월 29일 광화문 전화국 옥상에 최초의 천체투영관이 개관하였다. 이 투영기는 1970년 남산어린이회관으로 이전되었다가, 1975년 광진구에 있는 어린이회관으로 옮긴 후 2005년 퇴역하였다. 2017년은 천체투영관이 도입된 지 50주년이 해로, 2017년 10월 현재 우리나라에 88곳의 천체투영관이 운영중이며 연 200만명이 방문하는 중요한 천문교육시설이 되었다.

최근 한국소비자보호원에서 발표한 2006년도 소비자 위해 정보 통계분석 결과에 따르면, 위해 발생 장소별로 볼 때 가정에서의 안전사고가 가장 많은 발생 빈도를 보이고 있다. 최근 3년간 위해발생 접수 건수 중 가정 내발생 비율 역시 2004년 3,069건(35.2%), 2005년 4,392건(36.1%), 2006년 7,348건(49.5%)로 계속 증가 추세를 나타내고 있다. 가정 내 위해의 발생 원인은 식료품 및 기호품, 토지 건물 및 설비, 특히 현관, 계단, 복도, 욕실 등에서의 추락이나 미끄러짐, 충돌 등의 사고가 대부분인 것으로 조사되었다. 연령별로는 10세 미만의 어린이(64.3%)와60세 이상의 노인(58.4%)들에서 가정 내의 사고가 다른 장소에 비해 높은 비중을 차지하고 있었다. 가장 안전한 장소로 여겨지는 가정에서의 이와 같은 경향은 대부분 기본적인 안전 점검에 주의를 기울이지 않거나 안전을 소홀히 생각하기 때문에 발생된다.
