Purpose: This study aimed to assess hand hygiene (HH) compliance among visitors at a long-term care hospital in South Korea. Methods: The study was conducted at a 502-bed long-term care hospital located in Gyeonggi-do Province. From July 1 to August 15, 2017, including more than 6 weekends and one holiday, a trained observer covertly assessed visitors' HH at all five units (360 beds in total) of the study hospital building until the completion of 1,000 HH opportunities (i.e., 200 opportunities per unit). The modified World Health Organization (WHO) HH observation form was used. Instead of professional categories and the "before clean/aseptic procedure" moment, the estimated age range for each visitor were recorded in four categories: children (<14 years old), adolescents (14~18), adults (19~64), and the elderly (${\geq}65$). The collected data were analyzed using SPSS 22.0. Results: A total of 1,000 HH opportunities were observed from 766 visitors (an average of 1.31 per visitor) and the overall HH compliance rate was 20.3%. Overall, 53.7% of the HH cases were performed with soap and water. Among the 4 HH moments, the "after body fluid exposure risk" moment showed the highest compliance rate (83.5%); 93.9% used soap and water. The most commonly exposed potential body fluid among visitors was saliva (48.1%). Conclusion: For hospital visitors in long-term care hospitals, HH education programs including HH moments need to be developed and implemented. Further studies are necessary to evaluate visitors' HH compliance in various hospital settings and find the related variables influencing visitors' HH.

저자는 성장기 III급 부정교합자의 치료후 성장완료시까지 장기관찰 기록을 통하여 III급 부정교합치료 전략 수립에 도움이 되는 유용한 정보를 얻었다. 장기 관찰 결과는 다음과 같이 요약할 수 있었다. 첫째, 전치부 반대교합의 조기 개선시에 상악에서 상당한 전방성장이 많은 증례에서 관찰되었다. 둘째, 악골에 대한 정형적 치료에 의한 성장조절은 장기적인 관점에서 제한적인 효과만 인정되었다. 셋째, 반대교합을 가진 어린 환자에서 얻은 어떤 자료도 장기적인 관점에서 그 환자의 치료후 안정성을 예측할 수 있는 것은 없었다. 그러나 gonial angle은 어느 정도 예측의 가능성을 보였다. 넷째, 성장이 된 연령에서 하악에 대한 정형적 후방력이나 하악의 급작스런 위치 변화는 악관절에 좋지 못한 영향을 줄 수 있었다. 따라서 저자는 다음과 같이 III급 치료 전략을 제시한다. ${\cdot}$반대교합은 가능하다면 조기에 개선하는 것이 좋으며, 정형적 치료는 10세 이전에 1-2년 정도 사용하는 것이 좋겠다. ${\cdot}$ 이후에 바로 phase II 치료에 들어가지 말고 성장이 어느 정도 끝나는 시점까지 기다린다. 즉 여자는 14세, 남자는 17세 경까지 기다린 후에 교정치료로 마무리할 것인지 악교정 수술을 할 것인지 결정한다. 관찰 기간 동안에 성장에 영향을 줄 수 있는 기도문제, 혀자세, 습관, 제3대구치의 발육 등을 감독하고, 성장에 관한 자료를 채득한다. 이렇게 하므로서 앞에서 관찰한 치료 완료 후의 재발로 인한 재치료 문제를 줄일 수 있고,실제적인 치료기간을 단축할 수 있어 환자나 술자에게 모두 유익하다고 생각한다.

At Kyoto University, a continuous solar full-disk observation in CaII K line had been done during 44 years of 1926 - 1969. The observation was done with a Askania spectroheliograph on daily base. The images were taken on photographic plates. We started a project to archive these image data into a digital database which will be open to the public for scientific researches. One of the scientific usage of the database is to study the long term variation of the solar chromospheres. Since the area of CaII K plage area is a measure of solar chromospheric heating, we can do comparative study of the sunspot cycle and the chromospheric heating cycle of the sun. Another interesting field of scientific utilization of the database is the long term variation of the heating of terrestrial upper atmosphere. As was shown by Yokoyama, Masuda and Sato (2005), the area of the CaII K plage is a good proxy measure of solar EUV irradiation onto the upper atmosphere of the earth. Thus the completion of our database will serve to supply a basic and long-span data for upper atmospheric heating issues by the cooperative study with the Inter-university Upper atmosphere Global Observation NETwork (IUGONET) developed in Japan.

우리나라 동해안 6개 관측점에서 장기간 관측된 파랑자료를 이용하여 폭풍파의 출현 추세를 검토하였다. 한국해양과학기술원의 4개 정점(속초, 묵호, 후포, 진하)에서는 관측기간 동안 유의파고의 연별 평균값과 최대값의 주목할 만한 추세가 나타나지 않았다. 또한, 폭풍파의 연별 출현 횟수는 진하에서만 완만한 증가 추세가 나타났고 나머지 세 정점에서는 감소 추세를 보였다. 그러나 기상청 동해부이의 경우 유의파고의 연별 평균값과 최대값 및 폭풍파 연별 출현횟수가 2009년 이후로 매우 급격하게 증가하는 경향이 나타났으며 해당 자료의 연속성이 확보되지 않은 것으로 확인되었다.

This paper is to estimate the long and short term variations of mean sea level in Korean coastal waters by identifying interrelations among the mean sea level, atmospheric pressure and air temperature along the coast. For this, long-term tidal data observed at tidal and weather observation stations were brought into a statistical analysis. It was noted that, in a general sense, an inverse relationship exists between the sea level and the atmospheric pressure and a positive relationship between the sea level and air temperature, respectively. The maximum difference of monthly mean sea level was in the range of 21 to 25 cm at the eastern and southeastern coasts, meanwhile more than 30 cm being in both in southern and western coasts. It was also noted that mean sea level continues to rise in a long-term basis. Long-term variation of mean sea level trends to rise 0.10 ∼ 0.44 cm per year for each region. However, the long-term variation of mean sea level in the isolated islands shows a different trend, Ullngdo being 0.41 cm fall per year and Chejudo being 0.44 cm rise per year.

One-year-long groundwater-level data have been collected from 18 wells in Cheon-an area. The result of barometric efficiency, autocorrelation, cross-correlation and statistical distribution evaluated from the measurement data shows that groundwater-level measurements from observation wells are the principal source of information about aquifer characteristics. Data from WA-2 has high barometric efficiency as well as steady decreasing auto-correlation coefficient, which means nonleaky confined aquifer, Most aquifers in this study show the unconfined properties so that barometric efficiencies are mostly low and the coefficients of cross-correlation between groundwater-level and precipitation are commonly high. This study showed that the long-term groundwater-level monitoring data without artificial stress such as pumping would give accurate information about aquifer characteristics.

The ozone concentration measured by HALOE (Ver 19) from Oct. 1991 to Dec. 2003 is used for analyzing the variation of ozone concentration. The HALOE loaded in UARS is observing several gases in the atmosphere, from 10km to 80km. Fourier analysis of these data in the middle latitude northern hemisphere is reported in this paper. To detect any possible long term trends, the fourier transformed time series was back transformed after removing signals with time periods of less than 6 months. Although the results clearly show the strong annual cycle, it is difficult to show any long term trends from the fourier series. We also compared the ozone volume mixing ratio's from HALOE with that from the ground-based radiometry to evaluate the accuracy of microwave observation at Sookmyung Women's University.
