TNT 등가모델 및 KORA 시뮬레이션을 통한 에틸렌 위험특성에 관한 연구

차정민(Jeong-Min Cha) 한국위험물학회 2021 한국위험물학회지 Vol.9 No.1

In this study, ethylene was selected from the chemical products with relatively high volume at Ulsan Port, converted to the equivalent of TNT for each accident scenario, and overpressure was estimated through the distance from explosion to determine the damage. Assuming the “worst accident scenario”, the equivalent of ethylene, which is within 40m of the storm, is estimated to exceed the maximum of "crater" damage, which is about 50 minutes of leakage under the “alternative accident scenario”. In addition, if ethylene leaks, fires, and explosions occur during the unloading of port facilities, the extent of damage to “toxic”, “poolfire” and “vapor explosion” was quantitatively evaluated through hypothetical scenarios. The evaluation method used the KORA program supported by the Korea Chemical Safety Institute as a general-purpose program, and predicted the extent of damage to ethylene leaks, fires and explosions, and found that the scope of accident damage was reduced in “alternative accident scenario” compared to “worst accident scenario.” The damage impact range was reduced to 78% for toxicity, 4.45% for face-to-face fires, and 14.47% for steam cloud explosions. Furthermore, as the leakage time increased, the damage impact range increased by 125.98% compared to the leakage time of 5min, and the damage impact range increased by up to 158.72% at 20min.

Purpose: Advanced oxidation protein products (AOPP) has long been considered as a useful marker to estimate oxidative stress in the hemodialysis (HD) patients. However, it has not been clarified what clinical factors can affect the plasma level of AOPP in the HD patients. Based on these, We investigated the correlation between plasma AOPP level and clinical factor, known to be associated with oxidative stress, in the maintenance HD patients. Methods: Two groups (50 of normal healthy persons and 105 of stable HD patients) were independently subjected in this study, and statistical correlation between plasma AOPP level and several clinical factors were analyzed. Results: Plasma level of AOPP in the maintenance HD patients were higher than those in normal healthy group (52.11±16.08 μmol/L vs. 40.25±12.23 μmol/L, p<0.001). Plasma AOPP level of maintenance HD patients were significantly correlated with duration of hemodialysis, MDRD-GFR and daily urine volume. However, plasma level of AOPP in the maintenance HD patients were not affected by sex, diabetes, smoking, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, and those were not correlated with age, CRP and serum ferritin. It was demonstrated by multiple regression analysis that daily urine volume was the most important clinical factor which could affect the plasma level of AOPP (beta=-0.255, p=0.017). Conclusion: These results suggest that maintenance of daily urine volume is likely to be critical to reduce oxidative stress in the maintenance HD patients.

차정민(Cha, Jeong-Min) 한국비교과교육학회 2021 비교과교육연구 Vol.2 No.1

H대학은 학사경고로 인한 학업미성취 학생들의 학습역량을 강화하기 위한 다수의 비교과프로그램들이 운영되고 있다. 최근 학사경고로 인한 학업미성취 학생들의 프로그램 참여율이 점진적으로 낮아지고 있는 경향으로 나타나 학업미성취 학생들이 학기 중에 지원되고 있는 학습역량강화 프로그램으로 연계될 수 있는 방안이 필요하였고 이에 대한 대안으로서 ‘H-학습-MIND UP’프로그램을 기획하게 되었다. ‘H-학습-MIND UP’집단프로그램은, 학사경고로 인한 학업미성취 학생들을 대상으로 한 최근 3년간의 교내 요구도 조사 결과와 선행연구들의 결과에서 도출된 ‘심리적 개입’, ‘진로(가치관, 동기강화)’, ‘학습(전략, 방법, 관리)’에 중점을 두었다. 프로그램에 참여한 학생들의 학업성취도, 핵심역량 사전 사후 변화, 만족도의 자유응답을 분석한 결과는 다음과 같다. 첫째, 63.3%의 학생들이 다음 학기 성적에서 학사경고를 극복한 것을 확인할 수 있었다. 둘째, 자기관리 역량이 현저하게 향상되었으며, 셋째, ‘학업에 대한 열정 향상’, ‘학습전략에 대한 향상’, ‘자기 이해 향상’, ‘시간 관리의 중요성 인지’에서 긍정적 변화가 확인되었다. University H is running a non-subject educational programs to strengthen the learning capabilities of students who have been warned before. Recently, the program participation rate of students under academic probation appears to be gradually decreasing. In response, University H needed a way to link students under academic probation to the learning competency strengthening program supported during the semester. As an alternative to this, ‘H-Learning-MIND UP’ program was planned. Based on the results of the research on the needs of students under academic probation in the past 3 years and the results of previous studies. The ‘H-learning-MIND UP’ group program focused on ‘psychological intervention’ and ‘Life direction(life values, academic motivation)’, ‘learning (strategy, method, management)’. The results of analyzing the student s academic achievement, improved changes in core competencies, and free responses of satisfaction of the students who participated in the program are as follows. First, it was confirmed that 63.3% of students overcame the academic warning in their grades for the next semester. Second, self-management capabilities have been significantly improved, Third, positive changes were confirmed in ‘Improvement of passion for study’, ‘Improvement of learning strategies’, ‘Improvement of self-understanding’, and ‘recognition of the importance of time management’.

차정민(Cha Jeong-Min),정영진(Jung Yeong-Jin) 한국미술치료학회 2018 美術治療硏究 Vol.25 No.4

본 연구는 색채선호와 심리적 성향의 관계를 분석하여 심리진단에 있어서 색채 활용에 기여하고자 하는데 연구의 목적이 있으며 특히, 노란색을 선호할 때의 심리가 ‘Thinking’과 관련이 있는지에 대하여 주목하였다. 연구는 강원도와 전라북도에 소재한 306명(남: 59명, 여: 247명)의 대학생을 대상으로 하였으며, 측정도구로서는 13가지의 빨강, 주황, 노랑, 연두, 초록, 청록, 파랑, 남색, 보라, 자주와 회색, 흰색, 검정 등의 색채와, 7항목의 양측문장에 대한 SD(Semantic differential)평정척도를 사용하였다. 수집된 자료처리는 SPSS 24 프로그램을 이용하여 색채선호에 대한 빈도분석과 7항목의 문장에 대한 요인분석으로 하였다. 또한 노란색을 포함한 색채선호 집단에 있어서의 심리적 성향 차이를 알아보기 위해서는 요인분석에 의해 분류된 4개 그룹(Thinking, Feeling, Intuition, Sensing)에 대해 일원분산분석(one-way anova)을 실시하였으며 사후검정으로 LSD검증을 실시하였다. 본 연구의 결과는 다음과 같다. 첫째, 노란색 선호는 Thinking 보다 Feeling 과 관련이 높은 것으로 나타났고, 빨간색 선호는 Thinking 과 관련이 높은 것으로 나타났다. 둘째, 색채선호는 직관적 심리요인과 관련이 있으며 특히 연두색 선호에서 ‘Intuition’이 높고 ‘Sensing’은 낮게 나타났으며, 주황색 선호에서 ‘Sensing’이 높고 ‘Intuition’이 낮게 나타났다. The purpose of this study was to contribute to the utilization of color in psychological diagnosis by analyzing the relationship between color preferences and psychological tendency. In particular, we paid attention to whether the psychology of preferring yellow is related to “thinking”. The subjects of the study were 306 university students (male: 59, female: 247) in Gangwon Province and Jeollabuk-do. The measurement instruments were 13 colors, and the Semantic Differential Scale was used to scale for seven items on both sides. The processing of collected data was conducted via frequency analysis of color preferences and factorial analysis for the seven items on both sides by using the SPSS 24 program. In addition, one-way ANOVA was applied to four groups (Thinking, Feeling, Intuition, Sensing) classified by factor analysis in order to determine the difference of psychological tendency in color preference, including for yellow, among groups. The LSD test was performed by post test. The results of this study are as follows. First, the preference for yellow was related to “feeling” rather than “thinking”, and the “the thinking” was highly related to a red preference. Second, especially, in the preference of green-yellow color, the “intuition” is high and the “sensing” was low, and the preference for yellow-red was high on the “sensing” and low on the “intuitions”.
