보육료지원 확대의 여성 노동공급 효과 분석

이지완 한국사회복지정책학회 2020 사회복지정책 Vol.47 No.2

본 연구는 2013 년 전계층으로 확대된 정부의 보육료 지원이 영유아 자녀를 둔 여성의 노동공급에 미치는 영향을 실증적으로 분석하는 것을 목적으로 한다. 보육료 지원 확대가 영유아 가구에게만 영향을 미치는 점을 고려하여 정책의 인과적 효과를 파악할 수 있는 이중차이 분석법(Difference in Difference)을 활용하였다. 정책 확대 이전 시기는 2010-2011년, 이후 시기는2013-2015년으로 설정하여 비교하였고, 연구를 위해 한국노동패널조사 13, 14, 16, 17, 18차자료를 활용하였다. 나아가 본 연구는 정책의 효과가 여성의 학력과 아동의 연령에 따라 상이하게 나타났는지 살펴보고자 하였다. 이를 위해 분석 모형은 총 세 가지로 기본모형, 학력모형, 영⋅유아 모형으로 나누어 집단별로 정책효과를 분석하였다. 분석 결과, 기본모형의 분석 결과 보육료지원 확대는 영유아 모의 노동시장 참여율을 유의미하게 증가시켰다. 학력모형 분석 결과, 보육료 지원 확대로 인한 정책효과가 저학력 집단에서 더크게 나타났다. 영유아 모형에서는 영아 모(母)집단에서 유아 모(母) 집단보다 정책효과가 보다클 것으로 예상했으나 이는 학력모형에 비해 작은 차이였다. 이러한 결과를 통해 보육료 지원 정책이 양육부담으로 인해 노동시장에 참여하기 어려운 모의 노동공급을 증가시키는 데 긍정적인역할을 하고 있다는 것을 확인하였다. 보편적 보육의 확대가 2차 소득자, 즉 여성의 노동공급을증가시키며, 영유아 돌봄의 부담을 점차 탈가족화(de-familization)하는 데 기여하고 있는 것이다. 특히 보육료 지원은 저학력 여성의 노동참가율을 증가시키는 데 더 큰 정책효과가 있어 보육료지원이 양육에 대한 시간적, 금전적 부담을 보다 크게 느끼는 저학력 여성이 경제활동에 참여할 수있도록 보육 부담을 줄여주는 역할을 하고 있음을 확인하였다. 이에 따라 보육에 대한 부담을 보다 완화하고 영유아 모(母)의 경제활동을 지원할 수 있는 정책적 노력을 제언하였다.

국립서울대학교 초창기 운영방식의 구성

이지완 국민대학교 한국학연구소 2025 한국학논총 Vol.63 No.-

The conflict over the Seoul National University Plan has been mainly understood in the context of the ‘student strike against Seoul National University Plan’. However, the reason why the student strike which was led by the left-wing forces in education caused such a great consensus at the time was that it touched a number of sharp issues in the field of education of that time. In particular, the issue of university governance, represented by the conflict between the board of regents and university autonomy, was a key issue. The conflict over the governance was continued within the Seoul National University even after the end of the nationwide student strike. Therefore, this research argues that it is necessary to understand the conflict over the Seoul National Univeristiy Plan in a wider range of time which encompasses after the end of the student strike, and examines the early governance of Seoul National University. According to this research, the Department of Education stuck to its initial stance of investing the full authority of university governance to the external Board of Regents, despite the nationwide student strike. Nevertheless, conflicts and ‘ferment’ persisted at Seoul National University, where disparate members gathered, and exceptional procedures continued to emerge to cope with them. Above all, the academic background and scholarly lineage of deans and professors, and the time they had run each college since the liberation, gave them a justification for the governance of each college. The authority of external Board of Regents and the president of Seoul National University was not stable, clashing with deans and professors. All these facts suggest that the idea of a ‘University Governance by the external Board of Regents’ proposed by the Department of Education through the Seoul National University Plan did not actually work well, and the University Governance was constantly in the process of being constructed.

The purpose of this study is to evaluate the stream flow and water quality (SS, T-N, and T-P) behavior of Nakdong river basin (23,609.3 km2) by simulating the dam and weir operation scenarios using SWAT (Soil and Water Assessment Tool). The operation senarios are the simultaneous release for all dam and weirs (scenario 1), simultaneous release for all weirs (scenario 2), and sequential release for the weirs with one month interval from upstream weirs (scenario 3). Before evaluation, the SWAT was calibrated and validated using 11 years (2005-2015) daily multi-purpose dam inflow at 5 locations (ADD, IHD, HCD, MKD, and MYD), multi-function weir inflow at 7 locations (SHW, GMW, CGW, GJW, DSW, HCW, and HAW), and monthly water quality monitoring data at 6 locations (AD-4, SJ-2, EG, HC, MK-4, and MG). For the two dam inflow and dam storage, the Nash-Sutcliffe efficiency (NSE) was 0.56~0.79, and the coefficient of determination (R2) was 0.68~0.90. For water quality, the R2 of SS, T-N, and T-P was 0.64~0.79, 0.51~0.74, and 0.53~0.72 respectively. For the three scenarios of dam and weir release combination suggested by the ministry of environment, the scenario 1 and 3 operations were improved the stream water quality (for T-N and T-P) within the 3 months since the time of release, but it showed the negative effect for 3 months after compared to scenario 2. 본 연구의 목적은 낙동강유역(23,609.3 km2) 내 댐-보 연계운영 평가를 위해 SWAT (Soil and Water Assessment Tool)을 이용하여 댐보 운영 시나리오에 따른 하천 유량·수질 거동을 평가하는 것이다. 댐-보 방류시나리오는 댐-보 동시방류(시나리오 1), 보 동시방류(시나리오 2), 상류 보에서부터 1개월 간격의 순차방류(시나리오 3)로 모의되었다. 평가에 앞서 SWAT은 11년(2005-2015) 동안 5개의 다목적댐(안동댐, 임하댐, 합천댐, 남감댐, 밀양댐)과 7개의 다기능보(상주보, 구미보, 칠곡보, 강정보, 달성보, 합천보, 함안보) 및 6개의 수질관측지점(안동4, 상주2, 왜관, 합천, 남강, 물금)에 대하여 검보정 되었다. 유입량 및 저수량 검·보정결과 R2는 0.68~0.90, NSE는 0.56~0.79, RMSE는 0.94~1.74 mm/day 였으며, PBIAS는 –7.52~18.08%로 분석되었고,. 수질 R2는 SS는 0.64~0.79, T-N는 0.51~0.74, T-P는 0.53~0.72의 상관성을 나타었다. 댐-보 연계운영 평가를 위해 환경부에서 제시한 연계운영 시나리오 중 3개의 시나리오를 선택하여 모의하였으며, 시나리오에 따른 수문·수질 거동을 분석하였다. 분석결과 시나리오 2 에 비해 시나리오 1과 3은 연계운영 종료 이후 3개월 이전에는 수질 (T-N, T-P)개선 효과가 나타났지만, 3개월 이후로는 시나리오 2에 비해 수질이 나빠진 것으로 나타났다.

한국전쟁기 ‘1도 1교 방침’과 국립대학교 후원재단 설립

이지완 고려대학교 민족문화연구원 2025 민족문화연구 Vol.108 No.-

본고는 한국전쟁기 문교부의 ‘1도 1교 방침’의 결과로 탄생한 국립종합대학인 전북대, 전남대, 경북대의 설립 과정을 재정적 측면에 초점을 맞추어 검토한다. 문교부는 정부 수립 직후부터 재단과 시설이 미비한 사립대학을 정리하여 지역적·학과 계통적 편중을 조정하고자 했다. 한국전쟁기 각 지역에 국립대학교를 설치하여 기존 대학을 흡수하는 1도 1교 방침은 이러한 문제의식의 발현이었다. 또한 이 시기 1도 1교 방침은 문교부와 각 지역 행위자들 간의 상호 교섭 속에 나온 결과물이었다. 그런데 문교부의 1도 1교 방침은 기설된 사립대학 및 그 재단을 국립대학교 후원재단으로 포섭하여 재정적 토대를 마련하고자 하였다. 그렇기에 전북대, 전남대, 경북대가 설립되는 과정은 주체들의 행위과 선택이 교차하며 만들어 낸 지역의 고유한 동학에 좌우되었다. This article investigates the establishment of Jeonbuk, Chonnam, and Kyungpook National Universities under the ‘One National University per Province’ Policy during the Korean War, focusing on the financial aspect. In financial terms, the Ministry of Education established these institutions by mobilizing private resources while restricting public expenditure. As a result, provincial colleges and private colleges were consolidated into a national university in each province. In this process, the Ministry sought to incorporate private college foundations into newly created National University Foundations in order to secure a stable financial base. Therefore, the establishment of each National University and its foundation depended on the unique regional dynamics shaped by the actions and decisions of various local actors such as bureaucrats, local elites, Confucian scholars of Hyanggyo foundations and the board members of private college foundations.

Bladder Pain Syndrome Treated with Triple Therapy with Gabapentin, Amitriptyline, and a Nonsteroidal Anti-Inflammatory Drug

이지완,한동엽,정희종 대한배뇨장애요실금학회 2010 International Neurourology Journal Vol.14 No.4

Purpose: Bladder pain syndrome is a chronic disease that manifests as bladder pain, frequency, nocturia, and urgency. Gabapentin, amitriptyline, and nonsteroidal anti-inflammatory drugs are efficacious treatments for bladder pain syndrome. Here, we assessed the effect of triple therapy with these drugs in women with bladder pain syndrome. Methods: Between May 2007 and May 2010, we conducted a prospective nonrandomized study on 74 patients with bladder pain syndrome. Of these patients, 38 (11 men and 27 women; mean age, 55.9 years; range, 25 to 77 years; mean follow-up, 12.6 months) were administered the interstitial cystitis (IC) symptom scales (O’Leary-Sant Symptom Index) and visual analog scale (VAS) 1, 3, and 6 months after treatment to assess the efficacy of triple therapy. Results: The pretreatment O’Leary-Sant IC symptom score was 11.7, and the post-treatment scores were 4.4, 3.8, and 4.0 at 1, 3, and 6 months, respectively; the pretreatment problem index score was 10.5, and the post-treatment scores were 3.7, 2.7, and 2.9 at 1, 3, and 6 months, respectively. The pretreatment VAS score was 6.7, and the post-treatment scores were 1.8, 1.5, and 1.7 at 1, 3, and 6 months, respectively. The O’Leary-Sant IC symptom index and problem index and VAS scores improved considerably 1 month after treatment (P<0.05). However, the results at 1, 3, and 6 months after treatment were not significantly different (P>0.05). Conclusions: Triple therapy was sufficiently effective in patients with bladder pain syndrome and caused no significant adverse effects. However, large-scale studies should be performed to verify our findings.

The purpose of this study is to evaluate the relationship between heat wave and river water quality. The daily maximum air temperature (Tmax) of 91 meteorological stations of the Korea Meteorological Administration and 13 river water quality factors (DO, BOD, COD, TOC, TN, DTN, NH4-N, NO2-N, NO3-N, TP, DTP, PO4-P, Chl-a) of Ministry of Environment were analyzed. The correlation analysis was performed on Tmax and water quality factors, and the determination coefficients (R²) of DO, Chl-a, and TN with Tmax showed high values of 0.782, 0.609, and 0.691 respectively. To analyze the spatial impact between heat waves and water quality factors, the heat wave intensity (HWI) and heat wave duration (HWD) were calculated using the Tmax. The hotspot and spatial statistical analyses were applied for spatial impact evaluation. As a result of hotspot analysis, the heat wave index (HWD, HWI) showed high spatial pattern in the downstream of Nakdong River basin, and Chl-a and TN showed the same pattern. In case of spatial statistical analysis for water quality due to heat wave, the most obvious spatial variability was DO.

Xylooligosaccharide 의 랫트에 대한 아급성경구독성

이지완,이창승,윤세왕,양창근,이운택,류보경,강부현,박윤제 한국식품위생안전성학회 2000 한국식품위생안전성학회지 Vol.15 No.2

The subacute toxicity of xylooligosaccharide (XO) was evaluated in SD rats. Groups of 60 male and 60 female rats were orally administered with 0, 333, 1000 or 3000 mg/kg of XO for 13 weeks. The changes of body weight, food and water consumption were investigated for 17 weeks, while heamatological values and histopathological findings were investigated at the end of the 13 weeks and 17 weeks including 4 weeks of recovery periods. No death and toxic effects were observed during the test periods. There were statistically significant changes in several parameters, but these change had no direct relationship to dosage. Clinical changes were general occurrence and no specific toxicity was related to XO. Gross necropsy and histopathology revealed that no target organs were found in the treated mouse with XO. According to the results, no-observed effect level of XO is estimated to be above 3000 mg/kg.

The purpose of this study is to evaluate the groundwater level behavior of Geum river basin ($9,645.5km^2$) under future climate change scenario projection periods (2020s: 2010~2039, 2050s: 2040~2069, 2080s: 2070~2099) using SWAT (Soil and Water Assessment Tool). Before future evaluation, the SWAT was calibrated and validated using 11 years (2005~2015) daily multi-purpose dam inflow at 2 locations (DCD, YDD), ground water level data at 5 locations (JSJS, OCCS, BEMR, CASS, BYBY), and three years (2012~2015) daily multi-function weir inflow at 3 locations (SJW, GJW, BJW). For the two dam inflow and dam storage, the Nash-Sutcliffe efficiency (NSE) was 0.57~0.67 and 0.87~0.94, and the coefficient of determination ($R^2$) was 0.69~0.73 and 0.63~0.73 respectively. For the three weir inflow and storage, the NSE was 0.68~0.70 and 0.94~0.99, and the $R^2$ was 0.83~0.86 and 0.48~0.61 respectively. The average $R^2$ for groundwater level was from 0.53 to 0.61. Under the future temperature increase of $4.3^{\circ}C$ and precipitation increase of 6.9% in 2080s (2070~2099) based on the historical periods (1976~2005) from HadGEM3-RA RCP 8.5 scenario, the future groundwater level shows decrease of -13.0 cm, -5.0 cm, -9.0 cm at 3 upstream locations (JSJS, OCCS, BEMR) and increase of +3.0 cm, +1.0 cm at 2 downstream locations (CASS, BYBY) respectively. The future groundwater level was directly affected by the groundwater recharge by the future seasonal spatial variation of rainfall in the watershed.
