대학의 비정규직 행정직원 채용 확대 현상을 둘러싼 이슈와 쟁점: 채용자와 구직자의 관점 차이를 중심으로

박유민 한국교육행정학회 2024 敎育行政學硏究 Vol.42 No.1

본 연구는 사례대학의 비정규직 행정직원 채용 실태를 분석하고 비정규직 행정직원 채용이 대학의 운영에 어떠한 영향을 미치는지 분석하는 것을 목적으로 한다. 이 같은 연구 목적을 달성하기 위해 본 연구에서는 규모와 종류가 유사한 수도권 지역의 국립대학 1곳과 사립대학 1곳을 선정하여 각 대학의 정규직 관리자 2명 및 비정규직 행정직원 4명을 대상으로 사례연구를 진행하였다. 분석 결과 이들은 정규직으로 가는 경력 축적의 대안, 자유로운 시간 활용, 본인의 희망과 적성에 맞는 업무 선택이 가능하여 자발적으로 비정규직을 선택하였다. 또한, 대학은 비정규직을 정부재정지원사업의 전담 인력, 정규직 업무의 보조 또는 대체자로서 활용하여 대학의 인건비 절감, 유연한 인력 활용, 특정 업무를 위한 전문 인력 확보, 시보 기간 도입을 통한 역량이 떨어지는 직원 채용의 위험을 경감시키고자 하였다. 하지만 이들 비정규직 행정직원과 정규직 행정직원과 업무와 처우의 차이, 한정적인 근로기간 등은 비정규직 행정직원의 업무의 지속성과 전문성이 감소시켰고 이들 사이에 암묵적 갈등을 만들어 결국 이직을 고려하게 하였다. 따라서 대학이 비정규직 행정직원을 효과적으로 활용하기 위하여 첫째, 대학은 자체적인 인력 운용 방안을 마련하여 대학의 환경 변화에 능동적으로 대응해야 한다. 둘째, 대학은 비정규직 행정직원을 단순한 대체자로 인식할 것이 아니라 잠재적인 업무 역량과 다양한 활용 가능성에 초점을 맞춰야 한다. 셋째, 정부재정지원사업의 인력 운용의 구조적인 모순을 개선해야 함을 제언하였다. This study aims to analyze the employment status of temporary administrative staff in selected case universities and examine the impact of such employment on university operations. To achieve this objective, the study conducted a case study involving two regular administrative managers and four temporary administrative staff from one national and one private university in the metropolitan area, both of similar size and type. The analysis revealed that the temporary administrative staff chose their employment as an alternative for career accumulation towards regular positions, for the flexibility in time management, and for the ability to select tasks aligning with their preferences and aptitudes. Secondly, universities utilized temporary administrative staff as dedicated personnel for government-funded projects, as well as assistants or substitutes for regular staff tasks. Lastly, the employment of temporary administrative staff in universities led to reduced personnel costs, flexible utilization of manpower, acquisition of specialized personnel for specific tasks, and reduction of risks associated with hiring less competent staff through the introduction of a probationary period. However, the ambiguity of the temporary administrative staff's responsibilities led to a lack of accountability, differences in tasks and treatment compared to regular staff, and limited employment duration, which diminished the continuity and professionalism of their work and created implicit conflicts, ultimately leading them to consider job changes.

공간보간법(Kriging)과 계층적 의사결정 과정(AHP)을 이용한 농업입지 분석

박유민,김영호 한국지도학회 2011 한국지도학회지 Vol.11 No.2

세계화의 흐름에 따라 농업공간이 전통적 사회공간에서 국제적 경제공간으로 탈바꿈하고 있음에도 불구하고 국내의 농업 입지에 관한 계량적 연구는 매우 제한적으로 이루어져왔다. 특히, 미래의 시장성이 기대되는 작물인 복분자는 곡물대체 상업작물로서 지역적 특화에 성공하였다. 하지만, 농업 클러스터로서 복분자에 대한 자연·인문 환경을 고려한 입지연구는 현재까지 진행되지 못했으며, 일반적인 농산업 클러스터 입지 연구 조차도 부족한 실정이다. 따라서 본 연구에서는 농업입지 연구의 특성과 한국의 농업입지에 관한 기존의 선행연구를 검토하고 경상도 지역에서 복분자 클러스터가 입지할 수 있는 최적지를 제시하고자 한다. 이를 위해 공간통계기법인 Kriging을 이용하여 공간데이터를 구축하였으며, 다기준 분석법(Multi-Criteria Analysis)의 하나인 Analytic Hierarchy Process(AHP) 기법을 이용하여 복분자 클러스터 입지 요인들의 중요도에 따른 가중치를 산출한 후 최적의 입지를 도출하였다. 그 결과, 경상북도 남서쪽 지역, 경상남도의 서쪽지역과 중앙부 지역, 남쪽 해안가 지역 등이 복분자 클러스터의 최적지로 나타났다. 이러한 연구 결과는 경상도 내 복분자의 지역적 특화에 대해 실질적인 활용 가치를 지니며, 관련 담당자나 농업인에게 유용한 정보를 제공해 줄 것으로 기대된다. 또한 공간분석 방법을 적용한 농업의 최적 입지모델을 제시한다. The importance of quantitative spatial location analysis in agriculture became increased, as traditional agricultural society has been transformed into international market oriented economic society in the process of globalization. However, there are not many geographical studies about agricultural location analysis in Korea. As a case study about agricultural location analysis, this study investigates Korean wild berry, which has recently been considered as both market oriented and grain alternative agricultural product. Korean wild berry has been successful, in limited scale, as a regionally specific griculture product. However, there has been no study about location analysis about Korean wild berry considering natural and human environments for the agriculture. Therefore, this study investigates to provide optimal location for Korean wild berry agriculture in Gyungsang province. Meanwhile, this study overviews previous Korean literature about agriculture location. Kriging and Analytic Hierarchy Process (AHP) are applied for data management and spatial weight generation for Multi-Criteria analysis. The result shows that South-Eastern, Western, Southern areas in Gyungsang province are optimal locations for the wild berry agriculture. This study presents practical importance for agricultural planning in Gyungsang province. In addition, this is meaningful to provide spatial quantitative modeling application in agriculture location.

동박과 접착력 향상을 위한 폴리이미드 합성 및 접착특성 평가

박재연(Jae Yun Park),박종현(Jong Hyun Park),박유민(Yu Min Park),박노균(No Kyun Park),김윤호(Yun Ho Kim),원종찬(Jong Chan Won) 한국고분자학회 2017 폴리머 Vol.41 No.5

차세대(5G) 디스플레이의 발전으로 인하여 데이터 전송량이 점차 증가하므로, 신호전송이 빠른 대역대인 고주파 대역을 사용한다. 신호전송을 위한 회로는 동박과 폴리이미드 필름으로 이뤄진 유연동박적층판(FCCL)이 사용되는데, 고주파는 표면으로 신호가 흐르므로 두 소재 사이의 계면 조도를 낮춰 경로를 최소화하여야 한다. 그러나 저조도 동박을 사용하면 동박과 폴리이미드 수지와의 접착 강도가 떨어지게 되므로 이러한 문제점을 보완해야 한다. 본 연구에서는 동박과 접착력 향상을 위해 다양한 폴리이미드 구조를 설계하고, 아민계 실란 기능기를 도입한 폴리아믹산을 합성하였다. 다양한 구조의 폴리아믹산은 pyromellitic dianhydride(PMDA), 3,3"4,4"-biphenyltetracarboxylicdianhydride(BPDA), 4,4"-(hexafluoroisopropylidene) diphthalic anhydride(6FDA)와 m-tolidine(mTB), 2,2"-bis(trifluoromethyl)-[1,1"-biphenyl]-4,4"-diamine(TFMB) 등의 조합으로 합성하여, 이를 동박에 코팅하고 이미드화하여 FCCL을 제조하였다. 접착력에 대한 특성은 다양한 폴리이미드 구조에 따른 박리 강도 시험과 분리된 계면에 대한 AFM, SEM, 접촉각 측정으로 상관관계를 비교 해석하여 확인하였다. Since the development in mobile display requires high data transmission speed, there is a growing need in the development of flexible copper clad laminate (FCCL) for flexible printed circuit board (FPCB) that has a high signal propagation at high frequency range. The circuit for signal transmission uses FCCL which is composed of copper foil and polyimide film. The surface roughness of copper foil has to be low to reduce the pathway of signal because the current flows near the surface at high frequency range. However, such low roughness of the copper foil results in poor adhesion to polyimide, which is a problem that should be addressed. In this study, the poly(amic acid)s (PAAs) having various structures were synthesized and the silane functional group was introduced as end group to investigate the enhancement in the adhesion with the copper metal. Various polyimide structures were synthesized with the combinations of pyromellitic dianhydride (PMDA), 4,4"-(hexafluoroisopropylidene) diphthalic anhydride (6FDA), 3-aminopropyltriethoxysilane (TEOS), 3,3",4,4"-biphenyltetracarboxylic dianhydride (BPDA), m-tolidine (mTB) and 2,2"-bis(trifluoromethyl) biphenyl-4,4"-diamine (TFDB). The synthesized PAAs were casted on the copper foil and were imidized for the fabrication of polyimide for FCCL. The adhesion strength between the polyimide and the copper foil was investigated by peel strength test and interfacial characteristics was investigated with AFM, SEM, FTIR and contact angle measurement.
