서울시 노인의 개인 및 지역수준 주관적 건강상태 결정요인
조정민 한국생활환경학회 2023 한국생활환경학회지 Vol.30 No.1
This study is based on the development of an intervention program to improve the health care and health level of the elderly in seoul by considering the individual and regional influencing factors that affect the subjective health condition of the elderly living in the community of Seoul. A part of the 2021. The data of this study were integrated with data from the 'Community Health Survey', 'Life Safety Portal', and 'Seoul Open Public Data'. The subject this study were 5,737 peoples aged 65 years or older living in seoul. As a result of multi-level analysis including individual-level and regional-level variables, age, education level, household income, and alcohol consumption were identified as individual-level determinants of the subjective health status of the elderly. Regular exercise, number of chronic diseases, current smoking, satisfaction with public transportation condition, and satisfaction with medical service condition were identified as statistically significant determinants, and no statistically significant variables were identified as determinants at the regional level. The ICC value was 0.32, indicating that the overall region-level variables accounted for 3.2% of the variance in the elderly's health status. Based on these results, it is suggested that effective intervention programs and policies be developed by reflecting the results confirmed in this study in order to improve the health level of the elderly in the community in the future.
분광학(分光學)적 방법(方法)에 의한 중유회(重油灰) 용출액(溶出液) 중(中)의 Ni 정량(定量)에 관(關)한 기초(基礎) 연구(硏究)

중유회로부터 증류수로 용출시킨 중유회 용출액에서 금속 중 $Ni^{2+}$이온의 정량을 분광광도법으로 측정하고자 하였다. 또 중유회용출액 중 다량 존재하는 $V^{3+}$이온이 $Ni^{2+}$이온의 분광광도법적 정량에 미치는 영향을 알아보기 위하여 $Ni^{2+}$이온 ppm 대비 $V^{3+}$이온의 함량을 달리한 시료의 흡광도를 조사한 결과 $V^{3+}$이온의 함량이 $Ni^{2+}$ 함량의 50% 이하인 조건에서는 시료 중 $Ni^{2+}$이온의 정량이 분광광도법으로 가능함을 확인하였다. We tried to measure the fixed quantity of $Ni^{2+}$ion among the metals which were eluted by distilled water from the Fly Ash Leach Liquor(FALL) with a spectrophotometric method. In addition, we researched absorbance values which had different contained quantity of $V^{3+}$ion in contrast with $Ni^{2+}$ion ppm to find out the influence of the $V^{3+}$ion existed in the FALL on the spectrophotometric fixed quantity of $Ni^{2+}$ion. As a result, when $V^{3+}$ ion has below 50% of amount of $Ni^{2+}$ion, the fixed quantity of $Ni^{2+}$ion among the FALL was able to be confirmed by spectrophotometry.

This study was done to identify differences in health status by gender who are living alone. A part of the 2016 Community Health Survey data were used for analysis. The subject this study were 15,767 peoples aged 65 years or older living alone. General characteristics(age, education, medicaid status, dietary condition, smoking, drinking, physical mobility), physical health status and mental health status were measured. Data were analyzed by using descriptive statistics, t-test, ANOVA and stepwise multiple regression. As a results, medicaid status, dietary condition, drinking and physical mobility were factors affecting the physical health status of male and female elderly. Age and education were factors affecting the physical health status of female. Age, dietary condition and physical mobility were factors affecting the mental health status of male and female elderly. Medicaid status, smoking and drinking were factors affecting the mental health status of female. It is necessary to these factors should be considered in the development of intervention program for management of physical and mental health among elderly people in living alone in community.
Application of UAV Photogrammetry to Slope-Displacement Measurement
조정민,이종석,이병길 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.4
To reduce accidents caused by slope failures, disaster assessments and displacement measurements of steep slopes are conducted. Measurement values can vary greatly, depending on the technician's proficiency. Moreover, land creep and minute displacements are difficult to detect. In this study, we attempted to solve this problem using unmanned aerial vehicles (UAVs) and aerial triangulation. After a review of previous studies, a measurement precision of 10 cm for daily monitoring and sub-centimeters for precise monitoring were set. Twelve checkpoints were used, and the comparison results between the measured values using the total station and the aerial triangulation using the UAV were as follows. A virtual reference station (VRS) and three ground control points (GCPs) yielded 11.58 mm for the 3D (root-mean-square error) RMSE, and post-processed kinematic (PPK) and three GCPs generated 9.71 mm. By differentiating the results of multiple observations, the PPK processing results could achieve sub-centimeter accuracy. We verified that direct georeferencing using a VRS is sufficient for daily monitoring, and precise measurements require at least three GCPs. Geotechnicians can use VRS observations for economical slope monitoring in normal times, and accurate observations with GCPs when precise measurements are required.

The electrokinetic transport characteristics of salts were investigated using nitrate and sulfate accumulated saline greenhouse soil. Within 8 days, 95% of nitrate was removed from the soil, while sulfate removal was 19% for 8 days. The low removal of sulfate came from adsorption reaction on the soil particles or organic matter and precipitation with calcium. Divalent cations such as calcium and magnesium were transported toward cathode via electromigration, and most monovalent cation such as potassium was removed. The pattern of residual electrical conductivity was similar with that of sulfate. Based on the results, electrokinetic technique is effective to restore nitrate-accumulated saline soil, but is not effective to restore sulfate-accumulated soil.
大江健三郞の戰後「アメリカ占領認識」について : 『人間の半』と『不意の啞』を中心に
趙正民 대한일어일문학회 2001 일어일문학 Vol.16 No.-
본고에서는 전후 일본이 경험한 미국의 피점령을 大江建三는 어떻게 인식하였는지에 대하여 고찰한 것이다. 특히, 1958년에 발표된『人間の半』와『不意の啞』을 통하여 살펴보았는데, 작품의 특징으로서는 다음과 같은 점을 지적할 수 있다. 『人間の半』에서는 미국의 점령군에게 굴욕적인 대우를 받으면서도, 그것을 묵인하고 피해를 입은 자와 입지 않은 자가 명확히 구분되어, 피해자와 방관자의 구조를 일본인 스스로가 만들어 가는 과정이 고발되어 있다. 또,『不意の啞』에서는 점령군과 일본인사이에서 중간자적인 입장을 취하며, 점령군이상으로 일본인을 억압하는 일본인통역의 모습을 부각시킴으로서 <谷間の村>의 전쟁체험이 다름 아닌 일본인에 의한 것임을 강조하고 있다. 한편, 잡지나 신문을 통하여 두 작품이 발표된 昭和30년대의 사회적 분위기를 살펴보면, 미군기지와 그로 인해 다발하는 사건으로 인하여 반미감정이 고무되어있었던 점을 확인할 수 있다. 또한, 문예지에 발표되었던 문학작품에도 역시 반미감정을 고취시키는 성향이 보인다. 이러한 시대상황 속에 大江의 작품을 두고 생각해 보면, 大江는 일본의 피점령상황을 일본내부의 문제로 환기시키고 있는 것을 알 수 있다. 즉, 무력하게 피지배상황을 받아들이며, 일본인 스스로가 지배-피지배상황을 만들어 가는 과정을 그림으로서 일본인의 반성을 촉구하고 있는 것이다. 이러한 大江의 피점령인식은 이항대립적인 피점령구조, 또 약자의 내셔녈리즘을 극복하게 하는 가능성을 제시하는 것이라 할 수 있다.
