Purpose: This study aimed to investigate the effects of passive stretching exercise for the sternohyoid muscle, widely known as the accessory respiratory muscle, on pulmonary function. Methods: A total of 24 female university students without neurological, musculoskeletal, or cardiopulmonary dysfunction were included in this study. The subjects were randomly assigned to experimental (n=14) and control groups (n=10). Pulmonary function was assessed before and after passive stretching exercises using a spirometer (Pony FX, COSMED Inc., Rome, Italy). The experimental group performed 10 sets of three repetitions of passive stretching exercises for the sternohyoid muscle. The control group did not perform any exercise. Results: No significant changes in forced vital capacity and forced expiratory volume in one second were observed in both groups. However, a significant improvement in tidal volume, inspiratory capacity, and vital capacity (VC) was observed in the experimental group after passive stretching exercises, whereas no change was observed in the control group. Additionally, a significant improvement in maximal voluntary ventilation (MVV) was observed in the experimental group, whereas no change was observed in the control group. The changes in VC and MVV were higher in the experimental group than in the control group. Conclusion: Passive stretching exercises for the sternohyoid muscle can improve pulmonary function. In particular, they are effective in improving VC and MVV.

가상현실 기술이 발전하면서 다양한 영역에서 여러 목적으로 활용되고 있다. 하지만 사용자로부터 메스꺼움, 어지러움 등과 같은 멀미 증상에 대한 부작용도 함께 보고되고 있다. 이런 멀미 증상을 사이버멀미라고 말하며, 사용자에게 불편을 야기시켜 불쾌감과 스트레스와 같은 부정적 영향을 줄 수 있으며, 현재 사이버멀미의 발생 원인과 해결책에 관한 공식적인 표준이 없다. 본 연구에서는 이런 한계점을 극복하기 위해 정량적, 객관적 사이버멀미 평가법을 제안하였다. 10명의 20대 남성 대상으로 이동과 회전을 하는 가상현실을 경험하게 하면서 128채널의 뇌파를 측정하였다. 11개 영역에서 Delta와 Alpha 상대 파워를 계산하고, ROC curve를 통해 area under the ROC curve (AUC)가 가장 높은 값을 가지는 다중회귀모형을 도출하였다. 이렇게 도출한 다중회귀모형은 11개의 설명변수로 피험자가 응답한 사이버멀미의 정도와 비교하여 95.1 % (AUC = 0.951)의 정확성으로 사이버멀미를 구분하는 것이 가능함을 알 수 있었다. 이러한 결과를 정리하면 본 연구에서는 128 채널의 뇌파를 통해 멀미에 대한 객관적 반응을 확인하였으며, 뇌의 특정부위에서 반응이 있는 것으로 나타났다. 본 연구 결과와 분석법을 활용하면 추후 사이버멀미 관련 연구에 도움이 될 수 있을 것으로 기대된다. With advancements in technology of virtual reality, it is used for various purposes in many fields such as medical care and healthcare, but as the same time there are also increasing reports of nausea, eye fatigue, dizziness, and headache from users. These symptoms of motion sickness are referred to as cybersickness, and various researches are under way to solve the cybersickness problem because it can cause inconvenience to the user and cause adverse effects such as discomfort or stress. However, there is no official standard for the causes and solutions of cybersickness at present. This is also related to the absence of tools to quantitatively measure the cybersickness. In order to overcome these limitations, this study proposed quantitative and objective cybersickness evaluation method. We measured 128-channel EEG waves from ten participants experiencing visually stimulated virtual reality. We calculated the relative power of delta and alpha in 11 regions (left, middle, right frontal, parietal, occipital and left, right temporal lobe). Multiple regression models were obtained in a stepwise manner with the motion sickness susceptibility questionnaire (MSSQ) scores indicating the susceptibility of the subject to the motion sickness. A multiple regression model with the highest under the area ROC curve (AUC) was derived. In the multiple regression model derived from this study, it was possible to distinguish cybersickness by accuracy of 95.1% with 11 explanatory variables (PD.MF, PD.LP, PD.MP, PD.RP, PD.MO, PA.LF, PA.MF, PA.RF, PA.LP, PA.RP, PA.MO). In summary, in this study, objective response to cybersickness was confirmed through 128 channels of EEG. The analysis results showed that there was a clearly distinguished reaction at a specific part of the brain. Using the results and analytical methods of this study, it is expected that it will be useful for the future studies related to the cybersickness.

도시재생에 관한 연구는 2006년 이래로 10년이 넘는 기간 동안 활발히 진행되어오고 있다. 지금까지 많은 도시 재생사업 효과를 분석하기 위한 연구가 진행되고 있으나 대부분 정성적인 방법에 치우쳐 있다. 따라서 본 연구는 다양한 상업지역 도시재생사업이 진행 중에 있는 청주시 중앙동을 중심으로 도시재생사업의 효과를 정량적으로 분석하는 데 그 목적이 있다. 이를 위하여 유동인구, 공시지가 공실률을 도시재생사업 효과 분석 지표로 선정하였다. 분석시점은 도시재생의 효과가 본격적으로 나타나기 시작한 2013년을 기점으로 2011년부터 2016년까지이다. 분석결과, 첫째, 유동인구는 차츰 증가하다가 프로젝트가 활발히 진행되던 2014년에 약 65퍼센트의 증가율을 보였다. 둘째, 공시지가는 도시재생이 시작한 2011-2012 시점에 가장 큰 증가 폭을 보였고 2015년까지 증가폭이 점차 줄어들면서 2015-2016년에는 미세한 감소를 보였다. 마지막으로 공실률은 꾸준한 하향곡선을 그리며 27퍼센트에서 12퍼센트로 약 15퍼센트포인트가 감소하였다. 본 연구는 상업지역의 도시재생 효과를 정량적으로 분석한데서 학술적인 의의를 찾을 수 있다. The study on urban regeneration began in 2006 and has actively proceeded for 10 years. Also, there are a lot of studies related to urban regeneration have analyzed urban regeneration effects but have just focused on qualitative analysis. Therefore, this study has intended to analyze the urban regeneration effects of Junang-Dong, a central business district in Cheong City, where urban regeneration projects have been undertaking, in the manner of quantitative analysis. To reach this objective, we selected such indicators as floating population, public land price, a and vacancy rate, and set analysis time span from 2011 to 2016, when urban regeneration projects have been actively operated. As a result, this study has found the following results. 1) As for floating population, population index grew gradually and showed an drastic increase of about 65 percent in 2014 when the project was active. 2) Public land price of Jungang-Dong has been showed the greatest increase from 2011 to 2012 when the city started to regenerate, and slight decrease from 2015 to 2016 with the gradual decrease until 2015. 3) In terms of vacancy rate, there has been declined about 15 percent from 27 percent to 12 percent, with a steady downward curve. This study has dedicated itself to analyzing the urban regeneration effects quantitatively especially in commercial business district.

This study is for figuring out the relationship between the transition of the religious outlook and the design of worship space in Korean churches after the year of 2000. Analyzing the design samples of worship spaces which are appeared in architectural and interior design publications, it is found out that the modernity in architectural and interior design is presented in many worship spaces. And the progressive effort for the renewal of the worship service is projected to composition of the pulpit and others. But the conservatism of the Korean church has not been eliminated yet. These phenomena are considered to be same in the most cases of rural community church.
