국내 재생에너지 연계 수전해 청정수소 생산 발전 전략: 국내외 관련 연구의 비교, 분석을 중심으로
최영열,정인성,김태진 한국수소및신에너지학회 2023 한국수소 및 신에너지학회논문집 Vol.34 No.5
This study compares domestic and foreign research on renewable energy-based water electrolysis clean hydrogen. Domestic studies from 2010 to 2023 focused on technological efficiency, energy efficiency, and system efficiency, with few analyzing infrastructure and technology trends. Overseas research initially focused on technological efficiency and stability, but has since shifted to economic and environmental impact, policy effectiveness, industryuniversity- research cooperation, and sustainability. To improve water electrolysis technology production, this study suggests prioritizing technology stability over efficiency, resolving government regulations and resident acceptance issues, promoting industry-university-institute cooperation for rapid commercialization of research results, and developing a strategy for sustainable development of renewable energy-based water electrolysis technology.

崔英烈 고려대학교 의과대학 1975 고려대 의대 잡지 Vol.12 No.1
Although the hospital delivery are desirable to reduce morbidity and mortality rates of both infant and mother, the rate of hospital delivery varies in socioeconomic and cultural back ground. The lowered morbidity and mortality rates in more developed countries are undoubtedly associated with higher rates of better-equipped hospital care. The author therefore decided to investigate the pattern of delivery of rural Korea which might be of value in presenting the problem as well as in seeking the solution. 164 wives aged between 20 and 29 were interviewed in Ka Dock Island, Kyung Snag Nam Do. The statistical analysis of 646 deliveries that were experienced by 164 wives were made and the following results were obtained; 1. 99.4% of 646 deliveries had been taken at home while the hospital delivery had been only 0.6%. 2. Recently there showed increasing tendency of hospital delivery. 3. Young mothers favoured their deliveries at their own parents' home. 4. In almost all cases (95.4%), the deliveries were attended by unqualified personals while only 3.7% were attended by physicians and 0.9% by midwives. 5. 6.1% of total had taken place without any assistance with the much higher incidence in higher-aged group. 6. 65.9% had not used anything underneath during labor and 22.6% used a sheet of vinyl, while 10.5% used only paper bag. 7. 84.8% of placentas were disposed of into the sea while only 13.3% incinerated. Other mothers for the placental disposal were by burying, by disposal into the sea after incineration, and by means of others in the order of frequency.

Estrogen과 Prostaglandin F₂α가 白鼠 子宮 및 他 臟器의 Mast cell에 미치는 影響에 關한 實驗的 硏究
崔英烈,羅重烈,李壽鍾 고려대학교 의과대학 1982 고려대 의대 잡지 Vol.19 No.1
Influence of estrogen and prostaglandin F_(2α) on tissue mast cells in the female albino rat was studied. One hundred castrated female albino rats were treated with estrogen, prostaglandin F₂α, estrogen and prostaglandin F_(2α). They were sacrificed on day 1st, 2nd, 3rd, 4th and 5th to obtain the tissue for the mast cell count. The following results were obtained in the uterus, skin, and mesentery. 1. Mast cell in the uterine tissue was increased in number after the estrogen treatment on day 1st, peaked on day 3rd, and through day 5th compared with control group. 2. Mast cell in the uterine tissue was also increased in number after the prostaglandin F_(2α) treatment from day 1st to day 5th. 3. Significantly increased number of mast cell in the uterine tissue was also noted after estrogen and prostaglandin F_(2α) treatment through all experimental days as compared with control group. 4. In the skin tissue, mast cell in estrogen treatment group was increased in number on day 1st, but decreased after day 2nd through day 5th, as compared with control group. 5. But in prostaglandin F_(2α) treatment group, mast cell in the skin tissue was increased in number from day 1st through day 4th, but decreased on day 5th to control level. 6. In estrogen & prostaglandin F_(2α) treatment group, mast cell in the skin tissue was increased in number on day 1st, peaked on day 2nd, and returned to control level on day 3rd, 4th and 5th. 7. In the mesentery, mast cell after estrogen treatment was increased in number from day 2nd, peaked on day 3rd, and returned to control level on day 5th. 8. After prostaglandin F_(2α) treatment, mast cell in the mesentery was decreased in number on day 1st, but increased significantly on day 2nd, through day 5th. 9. In estrogen and prostaglandin F_(2α) treatment group, mast cells in the mesentery were decreased in number significantly on day 1st, but they were increased remarkably from day 2nd through day 5th.

한국에 있어서 림목에 기생하는 선충조사 IV. 수목 기생선충의 종류 및 분포
최영열,추호열,김영진,문일성,백현실 한국응용곤충학회 1992 한국응용곤충학회지 Vol.31 No.4
전국 국립공원 및 산지에서 154종의 수목을 대상으로 선충 종류 및 분포를 조사한 결과 수목과 관련이 있는 선충은 총 28속 73종이 밝혀졌다. Meloinema kerongens는 내장사 굴피나무, 느릅나무, 신나무에서 채집됨으로 새로운 기주식물로 밝혀졌다. 소나무재선충(Bursaphelenchus xylophilus)은 부산 금정산 일대에서만 발견되었고, 어리소나무재선충(B. mucronatus)은 제주도, 경남 마산, 진해 등지에서 발견되었고, 곤충기생성선충인 Prothallonema intermedium은 대구시 대덕산 리기다소나무, 제주도 제주시, 남원읍, 구좌읍, 애월읍 소나무에서 채집되었다. 수목별 기생선충 종류는 소나무가 32종으로 가장 많았고, 전나무 24종, 느티나무 20종, 감나무 19종, 상수리나무 18종 등의 순이었다. 선충종류별 분포지역은 Criconemella informis가 81지역에서 검출되어 가장 넓게 분포하고 있었으며, X. americanum 74, Tylenchorhynchus claytoni 51, C. macrodora 35, Hemicriconemoides varionodus, O. serratum이 31, Pararotylenchus pini 25, Hemicycliophora koreana 24, Aphelenchus avenae, C. pseudohercyniensis 22지역 등의 순으로 검출되었다.

Bursaphelenchus xylophilus was detected only in Pusan on Pi$\pi$us t thunbergii, B. mucronatus was detected in Cheju, Masan, and Chinhae.
