As industrialization and urbanization progress extensively, climate change is intensifying due to greenhouse gas emissions. In Korea, the average temperature increased, and the annual precipitation also increased due to climate change. In addition, the meaning of the solar term, which expresses seasons according to the movement of the sun, is also being overshadowed. Therefore, this study investigated the seasonal changes and solar-term changes of average temperature and precipitation observed in the past as well as simulated for future RCP climate change scenarios for five major regions (Capital Region, Gyeongsang, Chungcheong, Jeolla, and Gangwon). For the seasonal length, the length of summer became longer, the length of winter became shorter nationwide, and the precipitation in summer generally increased compared to the past. In the Chungcheong area, under the RCP 8.5 scenario, the length of summer increased by 46%, precipitation increased by 16.2%, and the length of winter decreased by 31.8% compared to the past. For the solar term, the temperature rose in all seasons. In the Chungcheong area, under the RCP 8.5 scenario, the temperature of major heat increased by 15.5%, and the temperature of major cold increased by 75.7% compared to the past. The overall results showed that the hydrological characteristics of the season and solar term were identified by region, which can be used as basic data to prepare policies to respond to climate change.

연구배경: 일반적으로 자가통증조절기가 자가진정조절을 위해 적합한 것으로 알려져 있다. 그러나 이 장치들은 몇몇 진정제 투여 시 너무 긴 최소 폐쇄간격을 가지고 있다 WalkMed사(Medex inc, USA)의 자가통증조절기는 폐쇄간격을 0으로 설정할 수 있으며 30 ml/h로 추가용량을 투여할 수 있다. 이번 연구에서는 환자 개개인의 요구에 맞추어 환자의 진정을 조절하기 위하여 위장치를 이용한 propofol 자가진정조절기의 가능성를 조사하였다. 방법: Propofol과 전산 프로그램된 WalkMed 주입장치를 이용한 자가진정조절법이 치과치료를 받는 24명의 건강한 환자에게 시행되었다. Propofol 지속 주입량은 2 mg/kg/h로, 추가용량은 5 mg으로 조절되었으며 치소 폐쇄간격은 0으로 설정하였다. Ketoloac 30 mg이 통증 조절을 위하여 진정법 시행 전에 근주되었다. 결과: 진정법 시행 동안 주입된 propofol의 평균량은 3.4 mg/kg/h이었으며 평균 추가용량은 1.6 mg/kg/h이었다. 시간 당 추가용량에는 많은 변이가 있었다(0-32). 모든 환자는 진정법 시행 동안 완전한 각성상태였으며 이러한 진정 법에 만족하였다. 진정 법과 관련된 주요한 합병증은 관찰되지 않았다. 결론: WalkMed사의 자가통증조절기를 이용한 propofol 자가진정조절법이 치과 치료를 받는 환자들에게 유용하게 사용될 수 있다.

Purpose: The purpose of this study was to investigate the knowledge and practice of patient-controlled analgesia use and management (PCA-UM) among nurses. Methods: Data were collected from 182 nurses employed by four general hospitals having more than 300 beds in Daejeon. The data were collected using self-report questionnaires from November 4 to November 20, 2015. Collected data were analyzed using descriptive statistics, t-test, and ANOVA. Results: The average nurses' knowledge about PCA-UM was 14.8 points out of 20. PCA-UM knowledge was significantly higher for nurses with experience in PCA education (t=3.55, p<.001). Most participants (91.2%) wanted to get PCA training, 86.8% of them provided PCA education to patients after surgery. Approximately 62% of participants regularly evaluated the level of consciousness of patients with PCA. Conclusion: Findings indicate that the knowledge and practice of PCA-UM among nurses were insufficient to provide safe and effective pain management to postoperative patients with PCA. Therefore, it is concluded that it is necessary to develop standardized PCA education programs for nurses to provide safe and effective pain management to postoperative patients with PCA.

Purpose: The purpose of this study was to identify the effects of the patient controlled analgesics (PCA) education program (including practicum) on post-op pain suffered by patients who have undergone gynecologic laparoscopic surgery. Methods: The research was designed for a nonequivalent control group before and after the test design. The subjects of this study were 54 in all and were divided into an experimental group and a control group. The program consisted of a brochure for PCA use and a practicum with an actual PCA instrument. Data were collected with questionnaires and observations and were analyzed on the basis of frequency, percentage, mean, standard deviation, ${\chi}^2$ and t-test. Results: Complaints regarding pain by the experimental group were significantly less than those of the control group in both post-op 24-hour and post-op 48-hour reporting. The experimental group pressed the PCA button much less frequently than the control group in post-op 24 hours. However, there were no significant differences in side effects between the two groups. Conclusion: Based on the results of this study, this PCA education program can be useful in the clinical nursing field and helpful for patients who use PCA.

To identify daily and annual changes in outdoor airborne fungi, it is necessary to shorten the collection cycle and increase the number of measurements. In this study, measurements were performed by employing an air sampler and potato dextrose agar media on the rooftop of National Research Institute of Cultural Heritage during a period of one year (August 2018 to July 2019). The collection cycle spanned the twenty-four seasonal divisions and the collection time was 2 p.m. and 11 p.m.. Meteorological elements were collected at intervals of one hour. Furthermore, the concentration of airborne fungi was monitored and correlation analysis with meteorological elements was subsequently conducted. Obtained results indicate that the concentration of airborne fungi is found to be highest in November, autumn, night, followed by autumn, summer, winter, and spring. The concentration, type, and dominant species of airborne fungi can vary depending on factors such as rainfall, typhoons, and yellow dust (fine dust). The concentration of airborne fungi indicates a strong positive linear relationship between precipitation, number of precipitation days, and relative humidity. The concentration of airborne fungi was related to the period of increase of dead plants in terms of nutrition source, and to the high relative humidity conditions including rainfall in terms of meteorological elements.

In this study, daily precipitation data and daily average temperature data of meteorological observatories in Daegu, Busan, Daejeon, Seoul, Mokpo, and Gwangju cities inland and offshore were analyzed by using moving average method. Were compared. Overall, summarizing changes in precipitation and temperature over the 24 seasons, precipitation and temperature in all six stations increased compared to the past 1960s. In the case of precipitation, precipitation increased at the end of July and early August, whereas precipitation in April, September and early October decreased. In the case of temperature, especially in February, the temperature increased, and in Mokpo, the temperature from August to December showed a general decline. Changes in precipitation and temperature due to seasons in the 24 seasons affect agriculture and our everyday life, and further research is needed to determine how these changes will affect agricultural water supply, crop growth and daily life. The results of this study can be useful.

하절기 사육환경 온도가 상승함에 따라 젖소가 받는 스트레스로 인한 생산성 저하는 저능력우 보다 고능력우에서 증가하게 되는데, 이는 높은 산유량을 유지하는데 필요한 기초 에너지 소모가 증가하여 체온이 증가하기 때문이다. 또한 고능력우들은 높은 산유량을 유지하기 위하여 더 많은 에너지와 영양소를 섭취하여야만 하는데 고온스트레스로 인하여 사료 섭취량이 감소, 에너지 부족현상을 다른 젖소들보다 더 심각하게 겪으므로 대사성 질병 발생이나 번식능력의 저하가 현저히 나타나기 때문이다(외기의 적정온도 : 4~24℃). (중략)

Purpose: The study examined the effects of preoperative patient controlled analgesia (PCA) education on postoperative pain, knowledge of PCA, and attitude toward pain medication. Methods: The participants were patients who underwent surgery in H University Hospital,and were assigned to PCA group (experiment group, n=30) or the control group (n=30). Results: Knowledge of PCA and positive attitude toward pain medication were higher in the experiment group than in the control group. Postoperative pain scores in the experiment group were significantly lower than those in the control group at 48 and 72 hr after surgery, but there was no significant difference at 24 hr after surgery. The experiment group had more positive attitudes on the medication than the control group. Conclusions: Preoperative PCA education could be an effective nursing intervention for pain management of patients after surgery.
