본 연구는 황금새(Ficedula narcissina)의 여러 아종 중 한국에 도래하는 아종의 형태학적 특징과 봄·가을 이동 양상을 파악하기 위해 2005년 4월부터 2008년 5월까지 전남 신안군 홍도와 대흑산도, 일본 이리오모테섬에서 각각 실시하였다. 형태학적 분류 결과 한국에 규칙적으로 도래하는 아종은 F. n. narcissina이었으며, 한국 미기록 아종인 F. n. elisae와 F. n. owstoni의 기록을 확인하였다. 황금새 성조 수컷은 아종간 형태적인 차이가 명확하였지만 미성숙한 개체와 암컷 형태를 띠는 개체는 아종간 매우 비슷한 특징을 보였다. 1회 여름깃 수컷의 경우 아종 F. n. narcissina는 월동지에서 부분 깃털갈이를 하여 성조 수컷과 비슷한 반면, 아종 F. n. elisae는 태어난 이듬해 여름까지 깃털갈이를 하지 않아 성조 수컷과 형태적으로 뚜렷이 다르며, 오히려 성조 암컷과 비슷한 특징을 보였다. 이같은 형태적 다양성과 깃털같이 전략의 차이 때문에 한국을 통과하는 개체군의 아종 분류가 매우 어려운 것으로 보인다. 조사기간 중 황금새의 가장 빠른 도래일은 4월 13일, 가장 늦은 도래일은 5월 17일로 나타났으며, 가장 많은 개체수가 통과하는 시기는 4월 하순으로서 2008년 4월 24일에는 14개체가 관찰되었다. 그러나 황금새는 봄철과 달리 가을 남하 시기에는 전혀 관찰되지 않아 봄·가을 이동경로를 달리할 가능성이 있음을 보였다. From April 2005 to May 2008, morphological traits and migratory patterns among the subspecies of the Narcissus Flycatcher (Ficedula narcissina) were studied at Hong Island and Heuksan Island in Korea, and at Iriomote Island in Japan. The regular migrants was F. n. narcissina in Korea, but two unreported subspecies, F. n. elisae and F. n. owstoni were also recorded in Heuksan Island, Korea. In our study, Narcissus Flycatchers were spring migrants observed from 13 April to 17 May, and a total of 14 individuals was recorded as a peak day count on 14 April 2008. However, there was no record in the autumn migratory seasons in Korea. This result suggests that the Narcissus Flycatcher is probably an elliptical migratory species which uses different routes in spring northward and autumn southward migrations. In morphology, adult males had distinct morphological differences, but immature and female-typed individuals had very similar plumages among subspecies. First summer F. n. narcissina underwent partial moults in wintering places and became very similar in appearance to adult males. In 'contrast, because F. n. elisae does not undergo partial moults until the summer of the 2nd calendar year, immature males of F. n. elisae were very resemble not adult males but adult females in appearance. Such morphological variances and differences in moulting strategies among subspecies often prevented the identification of Narcissus Flycatchers to the subspecies level.

국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

본 연구는 개인의 동기지향성 유형에 따라 자신의 직무에 대한 태도가 어떻게 달라지는가를 알아 보고자 하였다. 이를 위해 개인의 동기지향성 유형을 미동기화, 내재적 동기화, 외재적 동기화 그리고 이중동기화 집단으로 구분하였다. 이들에게 연구 1에서는 가설적인 직무상황을 제시하고 연구 2에서는 그들이 경험한 직무상황을 회상하게 하여 그 상황에서의 동기요인과 위생요인에 대한 태도를 측정하였다. 본 연구의 가설은 다음과 같다. 가설: 개인이 미동기화되어 있거나, 내재적으로 동기화되어 있거나, 또는 외재적으로 동기화되어 있으면 동기요인과 위생요인을 양극적으로 판단할 것이지만, 개인이 이중동기화되어 있으면 동기요인과 위생요인을 이원적으로 판단할 것이다. 위의 가설을 검증하기 위하여 두개의 연구를 계획하였다. 연구 1은 위생요인과 동기요인이 충실 또는 불충실한 4가지 가설적 직무생활을 피험자에게 제시하고, 각 상황에서 위생요인과 동기요인에 대한 태도를 측정하였다. 연구 2는 피험자들에게 실제 업무를 수행하는 과정에서 경험한 만족스러운 상황과 불만족스러운 상황을 회상하도록 하고, 그 상황에서의 동기요인과 위생요인에 대한 직무태도를 보고하도록 하였다. 연구 결과, 이중 동기회집단은 다른 집단들에 비해 위생요인과 동기요인을 더 이원적으로 판단하는 경향이 있었다. 끝으로 Herzberg 등(1959)의 2요인 이론이 개인의 동기지향성이라는 개인차에 의해 관찰될 수도 있고 관찰되지 않을 수도 있다고 논의하였다.

Recently surmountable amounts of genes are being cloned but it is hard to define the chromosomal location and functions of these genes. In this study, a new technique was developed for cloning genes expressed in the developing human brain with confirmed chromosomal location. The mRNAs were extracted from 18 week old human fetal brain, cDNAs were made by reverse transcription from these mRNAs and Uni-amp cDNAs having Uni-amp adapters a t both ends were made for subsequent PCR. To observe the distribution of the Uni-amp cDNAs on the chromosome, fluorescent in situ hybridization was performed with biotin labeled Uni-amp cDNAs. Among the chromosome bands showing strong hybridization with the cDNAs, lq21, lq25, lq32 and lq42 were microdissected from the chromosome hybridized with unlabeled Uni-amp cDNAs and amplified by PCR with Uni-amp primers. These amplified cDNA fragments were subcloned to plasmid vectors and the nucleic acid sequences were analysed. As a result 18 different clones were confirmed the chromosomal localization. They were categorized as 4 clones of well characterized genes, 3 clones showing low homology with known genes, 5 clones of simply registered uncharacterized human cDNAs, and 6 clones of unknown genes. The evidence suggests that the technique is very useful to clone the genes that express in the developing human brain, with confirmed chromosomal location. In addition, this cloning technique can be used to discover the new genes related with neuronal development in combination with functional screening method.

This study aims to investigate generation and physicochemical characteristics of Municipal Solid Wastes(MSW) generated from different sources in Kyungju. The source are apartments(low, high-rise), single family houses(centra1, outer), traditional market, office(city hall), factory, school, Park. The unit waste discharge rate of residential MSW excluding recyclable solid wastes was 0.47 kg/(capita . day). The maximum coefficients of variation for month and season were 1.23, 1.17, respectively. The bulk density of solid wastes was largely different for each sampling site, and the bulk densities of apartment district, single family house district and public area were 232㎏/m, 247kg/m, 170kg/m, respectively. The load factory of vehicle was 457kg/m. The percentage of combustible material to solid wastes was 86.5%. The physical compositions of solid wastes were food of 36.2%, Paper of 32.3%, plastic of 11.9%, glass of 6.5%, metal of 4.6%, textile of 3.0%, rubber of 1.8% and wood of 1.3%. The proximate analysis results of solid wastes showed moisture of 45.7%, volatile solids of 45.2%, and ash of 9.1%. In case of moisture content, the maximum value showed 66.7% in high-rise apartment district and the minimum value 14.0% in school district. Carbon, hydrogen, oxygen, nitrogen, sulfur and chlorine contents of combustible solid wastes were 48.4%, 7.0%, 25.9%, 1.3%, 0.2% and 0.4%, respectively. The low heating values of combustible solid wastes were 1,365 ~ 2,896kca1/kg (average 1,892kca1/kg) in residential area and 1,200∼3,878kca1/kg (average 2,178kca1/kg) in public area. Especially, the generation rate and the moisture content of residential MSW separating food wastes decreased 2.7 and 1.7 times and the low heating increased 2.1 times in apartment district.

The unique properties of graphene have earned much interest in the fields of materials science and condensedmatter physics in recent years. However, the biological applications of graphene remain largely unexplored. In this study, we investigated the conditions and viability of a cell culture exposed to graphene onto glass and SiO2/Si, using a human nerve cell line, SH-SY5Y. Cell viability was 84% when cultured on glass and SiO2/Si coated with graphene as compared with culturing on polystyrene surface. Fluorescence data showed that the presence of graphene did not influence cell morphology. These findings suggest that graphene may be used for biological applications.

Purpose : The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Materials and Methods : Digital radiographies of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size #2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. Results : In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52mm². The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. Conclusion : The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.
