공공부문에서의 블록체인 활용에 대한 주관적 인식:Q 방법론을 중심으로
이재완,송현호,김민한 한국지역정보화학회 2024 한국지역정보화학회지 Vol.27 No.1
본 연구에서는 Q 방법론을 활용하여 공공부문에서의 블록체인 기술 활용에 대한 다양한 이해관계자들의 주관적 인식을 탐구하였다. 본 연구는 블록체인 기술의 공공부문 적용・활용에 관한 기존의 선행연구와 전문가 인터뷰를 바탕으로 Q 진술문들을 작성하였고, 공공부문 내 다양한 전문적 배경을 가진 응답자들의 반응을 순위화하였다. 분석 결과, 네 가지의 유형이 도출되었는데, 이들 유형은 블록체인의 기술적 가능성 및 규제적 제약, 그리고 이에 대한 공공부문 이해관계자들의 인식 사이의 복합적이고 다차원적인 상호작용을 반영한다. 본 연구는 공공부문에서의 블록체인 기술 적용의 동학과 맥락을 제공함으로써 이론적・실천적 함의를 제공한다. 즉, 본 연구는 공공부문 혁신을 위한 블록체인 기술 도입에 관한 자결적 주관성을 이해하는데 기여할 것이다. 또한 공공부문의 목표를 달성하는 데 있어 블록체인 기술 활용에 대한 다양한 인식을 유형화함으로써 향후 공공부문에서의 블록체인 기술 도입의 방향성 제시에 기여할 것이다. This study employs Q-method analysis to explore the diverse perspectives and attitudes surrounding the application of blockchain technology in the public sector. It aims to uncover the tapestry of discourses and operant subjectivities of the various aspects and dimensions of implementing blockchain technology in public services. By using a set of Q-sample statements, participants from different professional backgrounds within the public sector ranked these statements per their viewpoints. The Q analysis revealed four distinctive patterns of opinions and attitudes, reflecting the interplay between technological possibilities, regulatory constraints, and public perceptions. These patterns emphasize the multidimensional nature of stakeholders' perspectives on the integration of blockchain technology into their work. Furthermore, the study offers insights into the dynamic nature of discourse surrounding the adoption of blockchain technology in public services. The study contributes to the understanding of operant subjectivity in the context of technology adoption and public sector innovation, and equips policymakers and practitioners with nuanced viewpoints on blockchain implementation, enabling them to make informed decisions when aligning blockchain technology with public sector objectives and requirements.

이재완 群山大學校 情報通信技術硏究所 1998 情報通信技術硏究論文集 Vol.2 No.-
As computer and communication technology is progressed, it is possible for systems to be interoperated in distributed systems. To provide the diversity services to user, system integration technology is needed. To do these, OMG proposed the CORBA which is middleware to be cooperated among distributed objects, regardless of specific plaforms and techniques. This paper proposes the reliable communication service based on the asynchronous event service suggested in OMG. A multicast service is also designed to be provided by using the distributor which is message agent.

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.
