시판 다소비 분말수프 3종(감자 수프/PS, 옥수수 수프/CS, 향신료 수프/CHS)에 대한 살균 목적의 감마선 조사(0, 1, 5, 10 kGy)가 이화학적 품질에 미치는 영향을 평가하였다. 아울러 감마선 조사 여부의 판별을 위하여 광자극발광분석(PSL), 전자스핀공명분석(ESR) 및 열발광분석(TL)의 적용가능성을 확인하였다. 시료의 수분함량 및 pH는 조사 여부에 상관없이 비교적 안정적이었으나, 기계적 색도는 조사선량이 증가할수록 PS 시료의 명도(L)는 감소하였고 황색도(b)는 증가하였다. 수프현탁액의 점도는 감마선 조사에 따라 크게 감소하였으며, PS>CS>CHS의 순으로 점도의 감소가 크게 나타났다. 분말수프의 감마선 조사 여부 판별시험에서 1 kGy 이상의 조사시료는 PSL 측정에서 5000 PCs 이상의 값을, ESR 측정에서 crystalline sugar 유래의 multicomponents signal을, 그리고 TL 측정에서 typical TL glow curve를 각각 나타내어 PSL, ESR 및 TL 분석의 적용가능성이 확인되었다. Commercial powdered soups, such as potato soup(PS), corn soup(CS), and chicken-herb soup(CHS), were gamma-irradiated at 0, 1, 5 and 10 kGy and subjected to physicochemical evaluation and identification trials by analyzing photostimulated luminescence(PSL), electron spin resonance(ESR), and thermoluminescence(TL). The changes in moisture content and pH of soup samples were negligible upon irradiation. The Hunter's color determinations showed that lightness (L value) decreased and yellowness (b value) increased as the irradiation dose increased in PS sample. The viscosity of irradiated samples was reduced in the order of PS, CS and CHS. The analyses of PSL, ESR and TL were applicable to the identification of irradiated powdered-soups at more than 1 kGy by detecting PSL photon counts/60 sec(over 5000), radiation-induced multicomponents-ESR signal, and typical TL glow curve at $150-250^{\circ}C$.

곽지영(Ji-Young Kwak),안재준(Jae-Jun Ahn),카시프 아크람(Kashif Akram),권중호(Joong-Ho Kwon) 한국식품영양과학회 2012 한국식품영양과학회지 Vol.41 No.10

섬유소 식품 중 바질과 정향의 방사선 조사처리 여부 확인을 위한 전자스핀공명분석법(ESR)의 개선을 위해 동결건조(FD), 상압건조(OD), 알코올건조(AE), 알코올세척건조(WAE) 처리하여 cellulose radical을 확인하였다. 비 조사 시료는 모두 singlet signal(g0=2.006)을 나타내었고, 조사된 시료의 경우는 모두 singlet signal을 중심으로 두 개의 side peak(g1= 2.023 and g2=1.986)가 6 mT 간격으로 나타나 cellulose 유래의 signal을 확인할 수 있었다. AE, WAE 처리한 정향의 경우, 조사유래의 cellulose radical의 ESR intensity가 증가 하였으며, central peak와 side peak의 비율도 판별에 매우 적합하였다. 그러나 FD 처리한 바질의 경우 ESR intensity는 가장 크게 나타났으나, signal ratio는 AE, WAE 처리하였을 때 더 이상적이었다. 또한 Mn<SUP>2+</SUP> signal 유래의 radical은 AE, WAE 처리한 시료에서 크게 감소하여, FD 및 OD에 비해 매우 명확한 조사여부 판별이 가능하였다. 따라서 AE, WAE 처리는 바질과 정향의 조사여부 판별방법을 크게 개선시키는 것으로 확인되었으며, 기타 향신료에 대해서도 ESR spectra 분석에 적용 가능할 것으로 판단되었다. An improved detection of radiation-induced paramagnetic faults was developed to identify the irradiation status of basil and clove. The effectiveness of different sample pretreatments, including freeze-drying (FD), oven-drying (OD), alcoholic-extraction (AE), and water-washing and alcoholic-extraction (WAE), were examined. All non-irradiated samples showed a single central signal (g0=2.006), whereas radicals representing two additional side peaks (g1=2.023 and g2=1.986) with a mutual distance of 6 mT were detected in the irradiated samples. AE and WAE produced the best results for irradiated clove in terms of intensities of radiation-specific ESR signals and their ratios to the central signal. However, FD provided the highest intensities of radiation-specific ESR signals for basil, whereas their ratios to the major signal were better in the cases of AE and WAE. Signal noise, particularly due to Mn<SUP>2+</SUP> signals, was observed, whereas it decreased in AE and WAE pretreatments. Based on our results, AE and WAE can improve the detection conditions for radiation-specific ESR signals in irradiated samples.

The purpose of this study is to examine the degree of political participation in reality and internet of the people with disability and to find factors affecting political participation in reality and internet . The data were obtained through telephone interview and personal interview with the people with disability. The final sample was consisted of 271 respondents. The data were analyzed using statistical techniques such as T-test, ANOVA and Multiple Regression. In this study, the factors affecting political participation of the people with disability in reality and internet were divided into three dimensions: social demographic factors, disability-related factors and political psychological factors. The major findings of this study were as follows: First, the social demographics factors affecting political participation of the people with disability in internet were religion and residential district. Second, the disability-related factors affecting political participation of the people with disability in reality were types of disability and cause of disability and the factors affecting political participation of the people with disability in internet were types of disability and grades of disability. Finally, the political psychological factors affecting political participation of the people with disability in reality were the beloning of the organization for the disability, the disability identity and political sense of efficiency. the political psychological factors affecting political participation of the people with disability in internet were the disability identity, political sense of efficiency and political confidence. The current findings suggest that intervention and policy aimed at improving social support system and formal services such as freedoam of movement, access right and the disabled quota system should be considered by policy makers.

Electron spin resonance (ESR) spectroscopy of gamma-irradiated fresh broccoli and kimchi cabbage was conducted to identify their irradiation history. Different pretreatments, such as freeze-drying (FD), oven-drying (OD), alcoholic-drying (ALD), and water-washing and alcoholic-drying (WAD) were used to lower the moisture contents of the samples prior to ESR analysis. The non-irradiated samples exhibited a single central signal (g0=2.0007) with clear effect of Mn2+, especially in kimchi cabbage. Upon irradiation, there was an increase in the intensity of the central signal, and two side peaks, mutually spaced at 6 mT, were also observed. These side peaks with g1 (left)=2.023 and g2 (right)=1.985 were attributed to radiation-induced cellulose radicals. Leaf and stem in broccoli, and root and stem in kimchi cabbage provided good ESR signal responses upon irradiation. The signal noise was reduced in case of ALD and WAD pretreatments, particularly due to Mn2+ signals. The ALD treatment was found most feasible to detect the improved ESR spectra in the irradiated samples.

With the recent development of self-driving cars, vehicles are not just a means of transportation but becomes a living space. Thus, it is important to provide a comfortable indoor environment to passengers in the vehicle. To achieve this, HMC Comfort Model ver.1, which predicts the thermal comfort of passengers, was developed in 2017. However, since this model was developed for Korean males in their 2-30s, it is difficult to apply it to females where different physiological and psychological responses are shown. Therefore, in this study, the data to develop comfort model specialized for gender were obtained and analyzed. Experiments were conducted on Korean females in their 2-30s in actual vehicles located in climate chambers with hot and cold conditions. During the experiment, skin temperature was measured and thermal comfort of subjects was evaluated. The results were compared with previous results of Korean males and necessity of specialized comfort model for women was confirmed through differences between two results.

국내의 다문화가족 자녀는 지속적으로 증가 추이에 있으며, 이들의 이중문화수용태도는 학교적응을 예측하는 보호변수로서 통합적인 탐색의 의의가 있다. 본 연구의 목적은 다문화가족 자녀의이중문화수용태도의 변화유형을 구체적으로 이해하고, 유형별 학교적응이 어떠한지를 살펴보는것이다. 즉 다문화가족 자녀의 이중문화수용태도의 변화유형을 도출하여, 이러한 변화궤적이 학교적응에 어떠한 영향을 미치는지 검증하였다. 이를 위해 한국청소년정책연구원이 구축한 다문화청소년패널 1차에서 6차 조사에 참여한 초등학교 4학년~중학교 3학년 시기 다문화가족 자녀 1,453명의 자료를 분석하였다. 다차원잠재계층성장분석을 활용하여 이중문화수용태도의 하위차원인 한국문화 지향성과 외국인부모문화 지향성의 변화궤적을 동시에 반영하여 변화유형을 도출하였다. 분석 결과, 이중문화수용태도에 따라서 이중문화수용형, 낮은 수준 동화형, 높은 수준 동화형, 문화무지향형의 네 가지 하위유형이 도출되었다. 각각의 하위유형별 학교적응의 궤적을 통해 학교적응정도를 알아본 결과, 한국문화와 외국인부모문화 모두에 긍정적인 이중문화수용형이 초기값이가장 높아 타 유형에 비해 상대적으로 긍정적인 학교적응을 보였으며, 낮은 수준 동화형과 두문화 모두에 뚜렷한 지향성을 보이지 않는 문화무지향형이 타 유형에 비해 상대적으로 가장 낮은학교적응을 나타냈다. 이상의 연구 결과를 바탕으로 다문화가족 자녀의 학교적응과 이중문화수용태도를 증진시키기 위한 실천적인 논의와 후속 연구를 위한 과제를 제시하였다 The number of children of multicultural families have been constrantly incresing, and studies have shown that their bicultural acceptance attitudes affects their school adaptation as a protective factor. This study is to investigate the subtypes of bicultural acceptance attitudes among children among multicultural families and track the trajectories of school adaptation in the subtypes. For this purpose, this study used six waves of longitudinal data from the Multicultural Adolescents Panel Study(MAPS, 2011-2016). The sample consisted of 1,453 adolescents from mulicultural families. This study employed multidimensional latent class growth analysis to identify subtypes of bicultural acceptance attitudes, given Korean cultural orientation and foreign-parent cultural orientation. The main results are as follows. First, the best fitting model identified four types of bicultural acceptance attitudes; Bicultural, low assimilated, high assimilated, culturally undirected groups. Second, looking at school adaptation by subtypes, the initial value of school adaptation was highest in the bicultural group, while low assimilated group and culturally undirected group showed the lowest level of adaptation. Based on these findings, the necessity of intervention and policy to enhance school adaptation and bicultural acceptance attitudes among children of multicultural families and suggestion was discussed.

재난 약자로서 중고령장애인의 취업상태 변화와 생활만족도 : COVID-19 전후를 중심으로

곽지영(Jeeyoung Kwak),고진경(Jinkyung Goh) 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.7

본 연구는 COVID-19 발생과 같은 사회적 재난 상황에서 중고령장애인의 취업상태 변화를 확인하고, 중고령장애인의 취업상태 변화가 생활만족도에 미치는 영향을 검증하였다. 분석에서는 장애인고용패널조사(PSED) 자료를 활용하였고, 중고령장애인 1,727명을 대상으로, SPSS 28.0 프로그램을 이용하여 기술분석, 상관관계분석, 회귀분석을 실시하였다. 분석결과 COVID-19 발생 후 취업률이 유의하게 감소하여, 재난 약자로서 중고령장애인의 현실을 확인할 수 있다. 또한, 장애정도나 타인의존 정도가 낮을수록, 건강상태나 자기효능감 수준이 높을수록 노동시장으로 새롭게 진입하였고, 여자일수록, 장애수용과 자아존중감, 자기효능감이 높을수록, 타인의존 정도가 낮을수록 노동시장에서 퇴출되었음을 알 수 있다. 미취업 지위가 유지되는 것에 비해 취업지위 유지 또는 취업으로 전환된 경우 생활만족도가 유의하게 높아졌다. 이 결과를 바탕으로, 중고령장애인이 노동시장 내의 지위를 유지하는 동시에 건강권을 보장할 수 있는 안전망 구축을 위한 실천적 · 정책적 제도 방안을 제시하였다. This study confirmed changes in the employment status of middle and aged people with disabilities in social disaster situations such as the outbreak of COVID-19 and verified the impact of employment status changes of middle and aged people with disabilities based on life satisfaction. The analysis used data from the Employment Panel Survey for Persons with Disabilities (PSED) which analyzed 1,727 middle and aged people with disabilities, and conducted descriptive analysis, correlation analysis, and regression analysis using the SPSS 28.0 program. Based on results of the analysis, the employment rate of middle and aged people with disabilities significantly decreased after the outbreak of COVID-19, confirming the harsh reality of middle and aged people with disabilities as vulnerable people in social disasters. Results also showed that when the degree of disability or dependence on others was low, and the level of health condition or self-efficacy was high, it was more likely for middle and aged people with disabilities to enter the job market. By contrast, when degree of dependence on others was low and disability acceptance, self-esteem, and self-efficacy was high, but the subject was a woman, it was more likely to be expelled from the labor market for middle and aged people with disabilities. Life satisfaction was notably higher in the case of subjects maintaining or entering a job compared to unemployed subjects. Based on these results, practical and policy measures were proposed to establish a safety net for middle and aged people with disabilities that can maintain their employment status in the labor market and at the same time guarantee their right to health.
