The rapid industrialization since the 1960s has caused considerable changes in the appearance of Korean cities. The huge demand and cityward tendency derived from the increase of population with such the expansion from 9 millions in 1960 to 43 millions in 2003, have resulted in number of problems such as the falling-off in the quality of life, amenity, and safety. And above all, the urban identities is not to be found obviously in the cities. With regard to these problems, the re-creation of cities should be emphasized to make environmental, economical, and social improvements and to restore human-oriented activities. In the course of making new improvements cities need to preserve the characteristics and maintain the concordance with their environments. In other words, the restoration of cities ought to be made in the aspect of continuity, which means the accession of genetic factors inherent in cities. In this background, concerning about the system on apartment house especially relating to environmentally sound restoration and comparing with that of Japan, this study proposes the direction needed in the development of urban space.

귀화식물인 가중나무는 도시지역에서 많이 발견된다. 그 주된 이유는 유.무성 생식이 잘 되기 때문이다. 종자의 확산과 맹아 출현에 의해 도시 서식지 내에서 쉽게 군락을 형성한다. 그러므로 가중나무의 종자의 확산과 발아분포 특성을 조사하는 것은 도시녹지 관리에 중요하다. 가중나무의 종자 확산 및 실생묘의 분포는 다음과 같이 조사되었다. 남산과 같이 환경조건이 최상일 때는 350개체, 퇴계원사거리 경우 50개체 정도가 발아해서 자란다. 이러한 종자는 풍향의 영향과 지형적 특성에 따라 확산 분포되는 경향이 있다. 조사대상지는 종자가 떨어지는 늦가을에서 봄까지 주로 북서풍이 불고 있으므로 남쪽으로 많이 비산 되었으며, 경사지인 퇴계원사 거리에서는 경사지의 아래쪽에 주로 분포하였다. 종자 발아에 의한 실생묘의 분포는 모수(母樹)의 수관폭과 비교하였을 때, 수관폭 내에 떨어지는 경우보다 수관폭 외곽에 떨어지는 경향이 있으며, 조사지역에서는 수관폭의 최대 7.5배까지 실생묘가 분포하였다. 주로 수관 폭의 2~4배 지점(20M 이내에 75% 분포)에서 군생을 나타냈다. 가중나무 종자 발아에 의한 실생묘 분포 확산으로 볼 때, 가중나무는 도시의 열악한 환경에서라도 급격한 개체수 증가가 있을 수 있으며, 이는 도시 토양의 보호라는 측면과 가중나무가 타수종과 경쟁에서 성공함으로 종 다양성 감소라는 측면을 같이 고려하여 관리방안을 모색해야 할 것으로 판단된다.

Street art operates within an already given visual order: the visuality of the modern city in which the regimentation of the image has become fully adaptive to-what Fredric Jameson termed-the logic of late capitalism. What is the relationship between street art and the hegemonic forms of the image dictated by the "city's rulers"? Does street art evoke an alternative kind of spectatorship? Can the unsolicited visual intervention in the life of the city open up an "optics" that resists the reifying patterns of the contemporary gaze? This paper follows Baudrillard's pioneering analysis of graffiti, arguing that the visuality of a certain kind of street images carries an important potential of challenging the hegemonic manner in which the contemporary image has come to dominate the field of vision.

The aims of this research are to analyze elementary preservice teacher's conception and causes of their misconceptions on biological reproduction and inheritance. In future, it would be also to provide useful data for the effective teaching-teaming method in the elementary school as well as opportunities to correct their misconceptions, which help elementary preservice teachers have the appropriate scientific conceptions. Thirty kinds of test questions were designed in science curriculum for elementary students and biology textbook for university students in order to develop reproduction and inheritance's concepts. The questionnaire was given to 166 junior students of university of education in a local city. All statistical analysis was performed using SPSS version 10.0 program. The major results are as follows: Among 30 test questions, 2 questions in plants, 5 questions in animals and 2 questions in gene were appeared as misconceptions over $50\%$. The major reason to hold the misconceptions was influenced by 'learning up to now' category. The selection reasons of response were significantly different between scientific conceptions and misconceptions in 10 questions by analysis of variance. The gender also showed statistically significant differences between scientific conception and misconception in 3 questions by $\chi^2$ test. The selection reasons according to gender were significantly different between male and female students in 5 questions. For the reasons in forming misconceptions, they may cause by stereotype, conscious priority, differences of experiences, interest or attention, lack of professional Knowledge, and so on. Therefore, it was concluded that this research may help elementary preservice teachers to reconsider their conception for reproduction and inheritance and to be successful in science instructions fur elementary students.

A disintegrin-like and metalloprotease (reprolysin type) with thrombospondin type 1 motif (ADAMTS1) plays a critical role in follicular rupture and represents a major advance in the proteolytic events that control ovulation. In this study, a 9,026-bp DNA sequence containing the full coding region, all 8 introns and part of the 5'and 3' untranslated region of the porcine ADAMTS1 gene was obtained. Analysis of the ADAMTS1 gene using the porcine radiation hybrid panel indicated that pig ADAMTS1 is closely linkage with microsatellite marker S0215, located on SSC13q49. The open reading frame of its cDNA covered 2,844 bp and encoded 947 amino acids. The coding region of porcine ADAMTS1 as determined by sequence alignments shared 85% and 81% identity with human and mouse cDNAs, respectively. The deduced protein contained 947 amino acids showing 85% sequence similarity both to the human and mouse proteins, respectively. Comparative sequencing of three pig breeds revealed one single nucleotide polymorphism (SNP) within exon 7 of which a G-C substitution at position 6006 changes a codon for arginine into a codon for proline. The substitution was situated within a PvuII recognition site and developed as a PCR-RFLP marker for further use in population variation investigations and association analysis with litter size. Allele frequencies of this SNP were investigated in seven pig breeds/lines. An association analysis in a new Qingping female line suggested that different ADAMTS1 genotypes have significant differences in litter size (p<0.01).

We analyzed how foraging area use changed in female Pipistrellus abramus during the breeding season. Radio tracking was used to follow 12 female P. abramus in Gyeongju City, from 2013 to 2015. We followed three bats in each of four stages of reproduction: early pregnancy, late pregnancy, lactation, and post-lactation. Our data showed that the usable area of a foraging site and the area that was actually used by bats in that site were different, and foraging site use also differed according to stage of reproduction. The bats used arable land the most, with use rates of 57%, 40.4%, and 73.2% during early pregnancy, late pregnancy, and lactation, respectively. Bats in a post-lactation state did not use arable areas at all and instead foraged over bodies of water 90% of the time. There was no difference in the use of each foraging environment between bats in early pregnancy and late pregnancy. However, bats in late pregnancy and those that were lactating did use arable land to different extents, and bats that were lactating and those that were post-lactation also used arable land and bodies of water to different extents.

This study focuses on exploring the behaviours of high-tech start-up firms in response to the policy interventions undertaken to promote regional innovation in South Korea since 1997. High-tech start-ups and their technological entrepreneurship are increasingly considered by policy makers and academics to play a crucial role in the generation of innovation and economic development. However, this study started from a basic concern of why government intervention does not necessarily result in an increase of regional innovation capacity. To explain this concern, we constructed a new conceptual framework of 'government dependency' and apply this to 'Daedeok,' a regional innovation system in South Korea, to explore the reproduction of path dependency as an impact induced by innovation policy. This conceptual framework was developed by remodeling path dependency approaches through a systemic and interactive lens. An empirical study used qualitative interviews of start-up founders to delineate the emergence of a new development path and the extent to which dependency was reproduced in the Daedeok regional innovation system. Empirical analysis suggested that 'reliance' and 'persistence' were the crucial factors in the production and reproduction of the government dependency. Some firms accepted dependency as reliance, but others regarded it as policy utilization. Thus, a critical juncture could not be clearly identified in actors' behaviour. It was also unclear if dependency had hindered innovation, but it was shown that the regional and institutional contexts strongly influenced the reproduction process. The study concludes that the construct of government dependency can also provide useful insights into policy learning as well as the success of government interventions.

Feeding ratio in relation to milk production, usage of silage, hay and minerals and vitamin suplement were investigated from 5 dairy farms located in the areas of Cheju city, Jochun, Hallim an Sung-up. In this survey conducted on the dairty cow of 51 farms in the four districts of Cheju-do, it was suspected that the reproductive disorders seemed to be high because of inadequate feeding of roughages (especially silage) and increasing feeding of concentrated feeds. The average milk production of dairy cows was 21.3 Kg in spring, 19.3 Kg in summer, 16.2 Kg in fall and 15.7 Kg in winter.
