이재완 청주대학교 산업과학연구소 1999 産業科學硏究 Vol.17 No.1
The marine algal flora and community structure of Jangho area, East coast of Korea, were investigated at two times June, 1998 and August, 1999. As a result, a total of 32 algal species - 6 greens, 7 browns and 19 reds - was identified. The flora was classified as the mixed flora based on species composition. In vertical distribution of intertidal marine algae, Chaetomorpha moniligera at the upper, Ulva pertusa at the middle, Sargassum thunbergii and Chondrus ocellatus at the lower zones, respectively. The dominant and subdominant species was Chondrus ocellatus, Ulva pertusa, Sargassum thunbergii, Chaetomorpha moniligera and Enteromorpha compressa. The biomass of the algal community on the average was 115.8 g dry wt/m²in dry matter.

An intertidal marine algae at Taean peninsula, west coast of Korea, was investigated at seasonally March ∼ December 2002. As a result, a total of 44 algal species - 3 greens, 12 browns, and 20 reds - was identified. The marine algal flora was classified as the mixed one based on the species composition. The common species occurring frequently in this area through the year were Hizikia fusiformis, Sargassum horneri, S. thunbergii, melobesioedean algae, Gelidium divaricatum, Chondrus ocellatus, Gymnogongrus flabelliformis, Acrosorium yendoi, Ceramium boydenii, and Neorhodomela aculeata.

An intertidal marine algal flora and community structure at Ulsan, east coast of Korea was investigated at two times June, 1998 and June, 2000 by a quadrat method along a transect line. As a result, marine algae were identified 29 species in 1998, and 25 species in 2000. The marine algal flora was classified as the mixed one based on the species composition. The dominant species were ULva pertusa in 1998 and Corallina pilulifera in 2000. The subdominant species Sargassum horneri, Corallina pilulifera in 1998 and Ulva pertusa, Enteromorpha linza in 2000. The vertical distribution pattern of intertidal marine algae was divided into three zones such as, Chaetomorpha moniligera (1998), Enteromorpha linza - Ulva pertusa, Corallina pilullfera - Sargassum thunbergu, S horneri (1998), S yezoense (2000) from upper to lower zones.

한국산 홍조류 붉은까막살 (Carpopeltis cornea)과 왕지누아리(Halymenia acuminata)의 ITS2 염기서열 비교
이재완 청주대학교 산업과학연구소 2000 産業科學硏究 Vol.18 No.1
Nucleotide sequences of the nuclear, ITS2 gene, as inferred from polymerase chain reaction amplified product, are introduced for Carpopeltis cornea and Halymenia acuminata in Korea .ITS2 sequences of C. cornea and H. acuminata are 366-bp, 359-bp long, respectively. Nucleotide difference of C. cornea and H. acuminata was 8 2% (30/366). The G+C content of C. cornea and H. acuminata was 45.4%, 44.4%, respectively. The 58s sequences of C. cornea and H. acuminata was showed the exactly same sequences of 129-bp long. Our ITS2 and 5.8s sequence data suggested that C. cornea and H. acuminata are not closely related group.

한국산 홍조 막우뭇가사리(Gelidium vagum Okamura)의 영양체 및 생식구조
이재완,이해복,이인규 청주대학교 산업과학연구소 1992 産業科學硏究 Vol.10 No.-
The vegetative structure and reproductive organs of Gelidium vagum Okamura were investigated in order to clarify the taxonomic characters of the species. The materials were collected at intertidal belt along the east, west and south coasts of Korea during May 1985 and June 1991. The plants grew singly on intertidal substratum by means of fibrous rhizoids. Primary branches became usually brother, tapering abruptly upward to form filiform branchlets. Broad surfaces of some main branches furnished with minute proliferations. Frond in section consisted of cortex, medulla and rhizoidal filaments. The reproductive structures were born on ultimate branchlets of the plant. The carpogonial branch was one-celled and developed from pericentral cells. The nutrient filaments developed at the base of carpogonial branches towards opposite direction of the trichogyne. The tetrasporangia occurred from fourth to sixth cortical cells from surface. They were divided mainly cruciately, or sometimes tetrahedrally. The taxonomic characteristics of the species, e.g., external morphology, occurrence of hairs, distribution of rhizoidal filaments, developmental sequence of carpogonial branch and nutrient filaments varied according to habitat of the populations.

이재완 대전대학교 지역협력연구원 2003 지역학연구 Vol.2 No.1
최근 지역복지환경변화롤 가져올 수 있는 사회복지사업법 개정이 있었다. 다 름 아닌 주민참여형의 지역복지체계의 구축과 지역사회중심의 민간목지 활성화 를 도모하고자 2003년 7월 사회복지사업법 개정이 그것이다. 이에 따라 주민조 직화운동과 지역사회와의 협력적 네트워킹을 통한 지역복지실천이 무엇보다 필 요하며 중요한 의의를 갖는다. 본 연구는 지역복지실천활동에 대한 사례연구로 써 이론적 실천적 합의를 통해 지역복지실천모형의 시준점을 얻고자 하였다. 지 역복지실천활동의 구체적 방법은 조직활동이라 할 수 있다 이를 위해 개인차원 이 아닌 조직차원의 운동을 통해 지역사회변화를 도모해야 한다. 지역복지실천 과정상에 가능한 많은 영역과 수준에서 지역주민과의 접촉점을 개발하고 확보하 는 것이 중요하다. 또한 조직활동의 주도하는 지역주민들의 의식화와 주체적 참 여 확대가 이루어져야 하며 나아가 지역사회에서 복지정치의 전면화가 이루어 져야 한다. 지방정치라는 공간속에서 지역복지가 우선순위가 되도록 조직활동을 강화해야 한다. 복지조직화사업을 통해 사회복지기관 • 단체 그리고 시민사회와 의 광범위한 연대와 협력관계의 툴을 구축해야 한다. 기관간 집단간 갈등관계를 해소하고 공동의 선을 이루기 위해 상호 노력해야 한다. 또한 복지네트워킹의 공간적, 영역별 범위툴 확장해야 한다. As a case study of welfare practice in a local area, this article discusses both theoretical and practical aspects of community welfare and suggests several important points for its future practices. It can be said that one specific method to practice community welfare δ an organizing activity which aims to change community through not an individual but people’ systematic participation. Such an organizing activity can be practiced by developing and establishing connection points with community people in as many areas and levels as possible. At the same time, it can be done by helping community people be conscious of the importance of community welfare. This will lead them to actively participate in the provision of welfare services and further help welfare agenda claim priority in local politics. A critical point is that such an organizing activity should lead to the development of a framework in which various actors, such as welfare agency, welfare institutions and civil organizations, cooperate to provide systematic services. Simultaneously , such a framework w피help resolve the conflicts between welfare agency and other welfare providers and expand the boundary of welfare network.

이재완 청주대학교 2015 産業科學硏究 Vol.33 No.1
The marine algal flora and community structure of Daechon area in Boryeong City, west coast of Korea, were investigated during August 2014 - January 2015. As a result, a total of 21 algal species - 4 greens, 5 browns and 12 reds - was identified. In vertical distribution of intertidal marine algae, Gelidium divaricatum (summer, winter) was at the upper, Sargassum thunbergii (su, wi), Enteromorpha linza (su, wi) at the middle, and Sargassum thunbergii (su), Enteromorpha linza (su), Caulacanthus okamuerae (wi) at the lower zones, respectively. The dominant species were Caulacanthus okamuerae (su) and Enteromorpha linza (wi).
