박성용,유호선,Park, Sung Yong,Yoo, Hoseon 한국플랜트학회 2021 플랜트 저널 Vol.17 No.2

지역난방의 운영적 측면에서 특정시간의 피크부하 완화를 통한 효율적인 열생산과 공급 및 지역난방 공급 중단 시 급탕 공급은 난방 대비 대체가 어려워 사용자 측면의 불편함과 공급자 측면의 애로사항을 해결할 수 있는 적용 기술이 요구되고 있다. 본 연구에서는 이러한 문제점을 해결할 수 있는 기술 중 열저장 능력과 급탕공급에 적합한 78℃급 수화물계 잠열축열조를 제작하여 지역난방 사용자 아파트 급탕공급설비에 현장 적용하였다. 본 시스템의 적용 결과 기존 공급방식 대비 급탕온도의 변화가 거의 없이 일정하게 사용자에게 공급됨을 확인하였으며, 피크 열부하는 평균 35% 감소와 비상열원으로서의 활용 가능성을 확인하였다. 또한 부하균등화에 따른 피크부하 감소로 기존 열 공급시설에서 10%의 열공급 여유와 신규 열공급시설 건설비용 및 열사용자의 공사비부담금이 각 5%와 10%가 감소됨을 확인하였다. In terms of district heating operation, efficient production and supply of heat by alleviating the peak load at a specific time require an application technology that can solve the inconvenience of the user and the difficulties of the supplier. In this study, a 78 ℃ class PCM heat storage tank suitable among the technologies that can solve these problems was manufactured and applied to the hot water supply facility for apartments in district heating users. As a result of the application of this system, it was confirmed that the supply temperature was constant to the user compared to the existing supply method. In addition, it was confirmed that the reduction of the peak load due to load equalization reduced the heat supply margin of 10% in the existing heat supply facility. And the construction cost of the new heat supply facility and the construction cost of heat users is decreased by 5% and 10%, respectively.

박성용,곽현정,김종엽,김재형,김의석 대한마취통증의학회 2005 Korean Journal of Anesthesiology Vol.49 No.4

Background: Sevoflurane anesthesia is associated with emergence agitation in children. This study examined the effect of a single intraoperative dose of ketamine and fentanyl on emergence agitation in children undergoing an adenotonsillectomy. Methods: Ninety children, 3-10 years old, undergoing an adenotonsillectomy were enrolled in this study. The patients were randomly assigned to receive either normal saline (control group), ketamine 1 mg/kg (group K), or fentanyl 1μg/kg (group F) after inducing anesthesia. Ketorolac 0.5 mg/kg was used for postoperative analgesia, and the anesthesia was maintained with sevoflurane. The recovery characteristics, including the time to extubation, the discharge time from the PACU, agitation, pain, and vomiting were assessed. Results: There were no significant differences between the three groups regarding the time to extubation and discharge from the PACU. The incidence of emergence agitation in the control group, group K, and group F was 46.7%, 13.3%, and 33.3%, respectively. The incidence of emergence agitation and the pain score were significantly lower in group K than in the control group (P < 0.05). The incidence of vomiting was similar in the three groups. Conclusions: Children undergoing tonsillectomy with sevoflurane and 1 mg/kg of ketamine given after induction had a reduced incidence of emergence agitation without a delay in recovery. However 1μg/kg of fentanyl had no effect on the incidence of emergence agitation.

Changes of Marriage Spheres in Korean Farming and Fishing Villages: A Case Study of Four Villages

박성용 영남대학교 민족문화연구소 2009 민족문화논총 Vol.43 No.-

Since the 50's, Korean villages have faced social, cultural, and economic changes. Changes of class consciousness and social hierarchy between Yangban(upper class) and Sangmin(lower class) have influenced class endogamy and local marriage. The purpose of this paper is to understand not only characteristics of matrimonial networks which have been subjected to change, but also Interrelationships between geographical mobility of females through marriage and dynamics of economic space in four Korean villages, Pilsan-ri, Jong-dong, Sinchon-ri. Tonggu-mi. The dominant kin group oriented value of these residents, which is based on Confucianism between married people, has greatly lost its significance. The established barriers to marriage with outside residents are being dismantled by the realities of globalization. The young people of the four villages generally seek their spouses not from "close areas" but from "distant areas" . Geographical distance is not an obstacle in marriage. Structuralized marriage spheres by social hierarchy have been taking place due to diverse transformations according to geographical, social, and economic characteristics In the case of Pilsan-ri, the ratio of females moving into the village after marriage from areas over 25km away is higher than the other 3 villages. This is because the economy of the village is stable due to the village's stock breeding and suburban farming business and, as the result, the females of Seoul and other major cities prefer spouses from this region Jong-dong residents show the highest percentage of females who move into the village from a 4km radius. This is because, even though Jong-dong is a Yangban village, the residents’ tendency to seek spouses from nearby areas has increased after an industrial complex was constructed there. Men from Sin-chon village had the highest ratio of marriage with women who lived outside a 25km radius from the village. Frequency of Yangban females marrying in or out of the village within the first 0~4km radius is very low. This may be because Yangban villages are distributed around the region. Class consciousness of Yangban has influenced local marriage networks. In the case of Tonggu-mi, marriages between village residents occurred more frequently. Finding spouses with similar economic status within the village or close proximity: preserve household properties and support their families. However, In recent, traditional alliances and networks of social relationship have been deconstructed. Since the 50's, Korean villages have faced social, cultural, and economic changes.
