본 연구는 충남에 거주하는 지체장애인의 이동권 현황을 파악하여, 이들의 이동권을 향상시킬 수 있는 방안을 제시하고자 한다. 이를 위해 2단계에 걸쳐 설문지를 개발하였으며, 일반적 특성, 외출 및 이동현황, 저상버스 및 장애인 콜택시 사용현황, 서비스 개선사항, 광역이동지원센터 관련 문항으로 구성되었다. 연구대상은 충남에 거주하는 지체장애인으로 총 219명이 참여하였다. 조사 결과 응답자 중 54.6%는 매일 외출하였으며, 17.0%는 거의 외출을 하지 않았다. 53.4%의 응답자만 홀로 외출이 가능했으며, 외출하지 않는 주된 이유로는 계단과 대중교통의 불편함을 꼽았다. 응답자 중 26.9%는 저상버스를, 71.1%는 장애인 콜택시를 이용했으며, 이를 위해 각각 66.57분, 42.65분 동안 기다린 것으로 나타났다. 78.7%는 광역지원센터가 필요하다고 한 반면, 49.8%만이 센터를 인지하고 있었다. 연구결과에 기초하여 이동권 향상 방안으로 특별교통수단의 확대, 지체장애인의 보행환경 개선, 광역이동지원센터 기능 활성화 등에 대해 논의하였다. This study investigated the general characteristics of mobility disadvantaged persons with disabilities, and to suggest implications to ensure personal mobility with the greatest possible independence for the physically disabled in community. The survey questionnaire included the categories as follows: the general characteristics of the participants, the status of outing and mobility, usage of low-floor buses & taxi for the disabled, service improvement, and mobile support center. Data collected from 219 with physical disabilities were analyzed for this purpose by using descriptive statistics. The study results showed that 54.6% of the total tended to go out everyday, and 17.0% rarely. 53.4% could go out without any assistance, and the major obstacles not to go out were stairs and inconvenience of public transportation. 26.9% used low-floor buses, and 71.1% preferred to use taxi for the disabled. The average waiting time for the usage of low-flow buses and taxi was 66.57 minute and 42.65 minute, separately. 78.7% insisted that the function of mobile support center in the community should be expanded, whereas only 49.8% recognized the role of mobile support center. Based on the study results, the researchers suggested to facilitate access by persons with disabilities to mobility aids, and to improve the actual state of pedestrian environment. In addition, the function of mobile support center should be expanded to help the mobility disadvantaged persons live independently in community, thereby contributing to the promotion of their quality of life.

All the input data settings of the 3-DFM model which is developed in this study are organized in Korean, and the model contains help function for each input data. Thus, it is designed to get detailed information about each input parameter when the mouse pointer is placed on the corresponding input parameter. This model also is designed to easily specify the geologic boundary condition for each stratum or initial head data in the work sheet. In addition, this model is designed to display boxes for input parameter writing for each analysis condition so that the setting for each parameter is not so complicated as existing MODFLOW is when steady and unsteady flow analysis are performed as well as the analysis for the characteristics of each stratum. Descriptions for input data are displayed on the right side of the window while the analysis results are displayed on the left side as well as the TXT file for this results is available to see. The model developed in this study is a numerical model using finite differential method, and the applicability of the model was examined by comparing and analyzing observed and simulated groundwater heads computed by the application of real recharge amount and the estimation of parameters. The 3-DFM model is applied in this study to Sehwa-ri, and Songdang-ri area, Jeju, Korea for analysis of groundwater flow system according to pumping, and obtained the results that the observed and computed groundwater head were almost in accordance with each other showing the range of 0.03 - 0.07 error percent. It is analyzed that the groundwater flow distributed evenly from Nopen-orum and Munseogi-orum to Wolang-bong, Yongnuni-orum, and Songja-bong through the computation of equipotentials and velocity vector using the analysis result of simulation which was performed before the pumping started in the study area. These analysis results show the accordance with MODFLOW`s.

복사전달모의를 통한 중적외 파장역의 민감도 분석 및 지표면온도 산출 가능성 평가

최윤영,서명석,차동환,서두천,Choi, Youn-Young,Suh, Myoung-Seok,Cha, DongHwan,Seo, DooChun 대한원격탐사학회 2022 大韓遠隔探査學會誌 Vol.38 No.6

In this study, the sensitivity of the mid-infrared radiance to atmospheric and surface factors was analyzed using the radiative transfer model, MODerate resolution atmospheric TRANsmission (MODTRAN6)'s simulation data. The possibility of retrieving the land surface temperature (LST) using only the mid-infrared bands at night was evaluated. Based on the sensitivity results, the LST retrieval algorithm that reflects various factors for night was developed, and the level of the LST retrieval algorithm was evaluated using reference LST and observed LST. Sensitivity experiments were conducted on the atmospheric profiles, carbon dioxide, ozone, diurnal variation of LST, land surface emissivity (LSE), and satellite viewing zenith angle (VZA), which mainly affect satellite remote sensing. To evaluate the possibility of using split-window method, the mid-infrared wavelength was divided into two bands based on the transmissivity. Regardless of the band, the top of atmosphere (TOA) temperature is most affected by atmospheric profile, and is affected in order of LSE, diurnal variation of LST, and satellite VZA. In all experiments, band 1, which corresponds to the atmospheric window, has lower sensitivity, whereas band 2, which includes ozone and water vapor absorption, has higher sensitivity. The evaluation results for the LST retrieval algorithm using prescribed LST showed that the correlation coefficient (CC), the bias and the root mean squared error (RMSE) is 0.999, 0.023K and 0.437K, respectively. Also, the validation with 26 in-situ observation data in 2021 showed that the CC, bias and RMSE is 0.993, 1.875K and 2.079K, respectively. The results of this study suggest that the LST can be retrieved using different characteristics of the two bands of mid-infrared to the atmospheric and surface conditions at night. Therefore, it is necessary to retrieve the LST using satellite data equipped with sensors in the mid-infrared bands.

최윤영,Dong Gyu Kim,안지영,김현기,Su-Jin Shin,Seohee Choi,Won Jun Seo,Chul Kyu Roh,Minah Cho,손태일,김형일,정재호,형우진,노성훈 대한위암학회 2019 Journal of gastric cancer Vol.19 No.4

Purpose: We aimed to evaluate the clinical characteristics of microsatellite instability in early gastric cancer. Materials and Methods: The microsatellite instability status of resected early gastric tumors was evaluated using two mononucleotide repeat markers (BAT25 and BAT26) and three dinucleotide repeat markers (D5S346, D2S123, and D17S250). Tumors with instability in two or more markers were defined as microsatellite instability-high (MSI-H) and others were classified as microsatellite stable (MSS). Results: Overall, 1,156 tumors were included in the analysis, with 85 (7.4%) classified as MSI-H compared with MSS tumors. For MSI-H tumors, there was a significant correlation with the female sex, older age, tumor location in the lower gastric body, intestinal histology, lymphovascular invasion (LVI), and submucosal invasion (P<0.05). There was also a trend toward an association with lymph node (LN) metastasis (P=0.056). In mucosal gastric cancer, there was no significant difference in MSI status in tumors with LN metastasis or tumors with LVI. In submucosal gastric cancer, LVI was more frequently observed in MSI-H than in MSS tumors (38.9% vs. 25.0%, P=0.027), but there was no difference in the presence of LN metastases. The prognosis of MSI-H tumors was similar to that of MSS tumors (log-rank test, P=0.797, the hazard ratio for MSI-H was adjusted by age, sex, pT stage, and the number of metastatic LNs, 0.932; 95% confidence interval, 0.423–2.054; P=0.861). Conclusions: MSI status was not useful in predicting prognosis in early gastric cancer. However, the frequent presence of LVI in early MSI-H gastric cancer may help guide the appropriate treatment for patients, such as endoscopic treatment or limited LN surgical dissection.

중등학교 교실의 이산화탄소(CO₂) 관리를 위한 지능형 창호개폐 작동 프로세스

최윤영,이현수,Choi, Yoon-Young,Lee, Hyun-Soo 한국교육시설학회 2018 敎育施設 Vol.25 No.4

The school classroom is a common living place where students spend 7 to 14 hours a day to prepare for their careers. Therefore, if the ventilation of the classroom is not properly performed, it may lead to the deterioration of learning ability due to the unclear air. The concentration of carbon dioxide in the classroom is reported to be high, and the increase in carbon dioxide concentration has a negative effect on the learner's academic performance. In this context, the purpose of this study is to propose a methodology for intelligent and responsive window opening-closing operation process that can reduce the concentration of $CO_2$ in the classroom in order to build a support space that can create an effective teaching-learning environment for adolescents. The specific objectives are as follows. First of all, we define the concept of window opening-closing operation. Secondly, twe develop the operation process of window opening-closing. Thirdly, we develop an algorithm for real-time window opening and closing (process) (Window Opening-Closing Operation Process). Finally, we verify the intelligent responsive window opening-closing operation process through developing examples of window opening-closing operation process using the parametric design program. This study is a preliminary study to develop algorithms necessary for window opening-closing operation. Based on the first-order algorithm, We simulated window opening-closing operations according to a hypothetical scenario. As a result, This study can show that the window is open and close depending on the $CO_2$ concentration, but the $CO_2$ concentration in the room is higher than outdoors. Consequentially, we suggest that it is necessary to develop an algorithm to supplement these results because window is often not working when the temperature difference between indoor and outdoor in winter is large.

최윤영,이미준,김은실,이지원,권영인,하유미,Choi, Youn-Young,Lee, Mi-Joon,Kim, Eun-Sil,Lee, Ji-Won,Kwon, Young-In,Ha, Yu-Mi 중소기업융합학회 2021 융합정보논문지 Vol.11 No.4

본 연구는 뇌졸중 환자에게 제공한 음악요법이 우울과 재활 동기에 미치는 효과를 규명함으로써 음악요법을 뇌졸중 환자의 간호중재방법으로 활용하기 위한 근거를 마련하고자 시도되었다. K병원에 뇌졸중 진단으로 입원한 33명을 대상으로 취침 전 30분 동안 사전에 선정된 10곡의 음악을 3일간 듣게 하였다. 그 결과 인구사회학적 특성에서 남성 참여자(25명)가 여성(8명) 참여자에 비해 많았고 연령대는 40대와 50대가 25명(75.8%)에 달했다. Wilcoxon-signed rank 검정을 사용하여 분석한 결과 우울과 재활 동기에는 영향이 없는 것으로 나타났으나, 인지수준이 낮은 MMSE 1그룹(≤ 29)에서 음악요법이 우울감소에 효과가 있는 것으로 확인되었다. 이 결과로 음악 요법의 효과성을 높이기 위한 다양한 간호중재로 적용하는데 기초자료로 제공될 것을 기대한다. This study aimed to evaluate the effect of music therapy on depression and rehabilitation-motivation provided to stroke patients, thus achieving evidence-based music therapy as a nursing intervention method for patients. Thirty-three people who were hospitalized for stroke diagnosis at K-Hospital were required to listen to 10 pre-selected songs for three days before bedtime. According to the general characteristics, the proportion of male participants (25, 75.8%) was higher than female (8, 24.2%), and by age group, 6(18.2%) were in 40s, 19(57.6%) were in 50s and 8(24.2%) were aged 60 or older. The study data were analyzed using Wilcoxon-signed rank test. As a result, music therapy does not affect depression and rehabilitation-motivation. However, it was shown to be effective in reducing depression in MMSE group 1 (≤ 29) with low cognitive levels. It is expected that this study can be used as an evidence for music therapy which can be applied as a way to increase the effectiveness of nursing intervention.

최윤영,Choi, Yoon-Young 한국치위생학회 2021 한국치위생학회지 Vol.21 No.2

Objectives: The aim of this study was to investigate the effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.
