On April 5, 2019, 5G communication technology was commercialized in South Korea. It is expected that virtual environment technology will be used in various fields thanks to development of telecommunication technology. However, failure to address the problem of cyber motion sickness, a user side effect of virtual environment technology, will limit the activation and diversity of the technology's application areas. In previous studies, there were many ways to improve symptoms through visual environments and user movements. In this study, the results of a study were checked to see if the effects of symptom mitigation can be obtained by listening to a particular sound source of cyber motion sickness among users using a virtual environment.

The Gallery of Casa del Agua in Jeju Island was demolished by Jeju local government on March 6 in the last year. In the meanwhile, a lot of people including the architectural field had denied the demolition. Regardless of sustained efforts in order that the building could be preserved as a work, Jeju government ended up with demolishing the gallery. The Gallery of Casa del Agua was a temporary building constructed as a model house of Casa del Agua. As the remaining period of the temporary building had passed, it was on the verge of demolition by Jeju government. Casa del Agua is 'dwelling of water' in Korean, and the building was the last posthumous work of Mexican architect Ricardo Legorreta. Knowing from the expression of 'dwelling of water', this house is a dwelling work of him. Through this work, his architecture languages that he had pursued contained in dwelling could be looked into. This study examined the background and course of demolition of the Gallery of Casa del Agua, 'dwelling of water' and arranged problems in the course of demolition. Then, the fact that the Gallery of Casa del Agua as an architecture work of Ricardo Legorreta included his architecture languageswas analyzed. For this, his universalarchitecture languages were examined and how the architecture languages were applied to the Gallery of Casa del Agua was analyzed. As a result, it could be known that languages of composition and languages of emotion consistently shown in his works were represented in the Gallery of Casa del Agua.
가정의학회지에 실린 중재 관련 비무작위연구논문의 질 평가
김형준,김수영 대한가정의학회 2009 Korean Journal of Family Medicine Vol.30 No.2
Background: Since the Korean Journal of Family Medicine (KJFM) started publishing in 1980, randomized controlled trials (RCTs) and non-randomized controlled studies (NRSs) consistently have increased in quality and quantity. Although there have been several studies on the quality assessment of RCTs in Korea, there has been no study on quality assessment of NRSs. Thus, this study evaluated NRS in the KJFM to assess the quantity and quality. Methods: Upon extracting NRSs for assessing the intervention effects from all the articles published in the KJFM from 1980 to 2006, assessments were made on methodological index for non-randomized studies (MINORS). Also, the analysis were made upon the proportion of NRSs within original articles according to two categories (comparative study, noncomparative study). The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed. Results: A total of 34 trials on NRSs were selected. In 1980s, 0.65% of the total selected original articles, in 1990s, 1.54%, and in 2000s 5.11% were NRSs. According to the research designs, the mean scores of MINORS were before and after study 8.5, interrupted Time Series 9.7 (out of 16), controlled before and after 13.5, quasi randomized trial 12.6, and non randomized trial 13 (out of 24). Before and after design was the most frequently used (55.9%). Conclusion: Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used before and after design. Thus, there should be studied using appropriate research methods in the future. 연구배경: 1980년 가정의학회지가 발간된 이후로 다양한 연 구설계방법의 연구논문이 게재되면서 비무작위연구논문의 양적 및 질적 성장을 가져왔다. 국내 연구에서 무작위대조시 험에 관한 질 평가는 일부 있었지만 아직까지 비무작위연구 논문에 관한 질 평가가 이루어진 적은 없었다. 방법: 1980년부터 2006년까지 발행된 가정의학회지의 원저 1,343편을 대상으로 중재 관련 비무작위연구논문을 분류한 후, Methodological Index for Non-Randomized Studies (MINORS) 를 이용해 질 평가를 시행하였다. 또한 원저에서 비무작위연 구가 차지하는 비중을 분석하고 연도별 연구방법에 따른 분 류 및 항목별 점수와 평균 점수를 분석하였으며, 연구설계별 총점 및 평균점수를 측정하였다. 결과: 포함된 중재 관련 비무작위연구논문은 총 34편이었다. 연도별로 1980년부터 1990년까지는 1편으로 원저의 0.65%에 불과하였지만, 1991년부터 2000년까지는 12편(1.54%), 2001 년부터 2006년까지 21편(5.11%)으로 양적증가를 보였다. 연 구설계방법의 종류에 따른 평균점수는 전후연구 8.5점, 단락 시계열 연구(Interrupted Time Series, ITS) 9.7점, 비교 전후 연구 (Controlled Before and Aer studies, CBA) 13.5점, 준무작위 시 험(Quasi-Randomized Trial, QRT) 12.6점, 비무작위 시험(Non Randomized Trial, NRT) 13점으로 낮게 측정되었다. 가장 흔한 연구설계방법은 전후 연구로 55.9%를 차지했고 QRT, NRT/ QET는 각각 14.7%, 2.9%로 많지 않았다. 결론: 가정의학회지에 게재된 비무작위연구논문의 비중은 지 속적으로 상승하고 있지만 방법론적 질은 그다지 높지 않다. 또한 대조군이 없는 전후 연구가 대부분을 차지한다.
