Objectives: The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas. Methods: The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants' frailty. Results: The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy. Conclusions: More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.

이 연구는 건강플러스 행복플러스 사업의 기초자료를 활용하여 우리나라 지역사회에서 자살생각 및 자살시도의 수준을 알아보고, 이들과 사회적 참여와 신뢰의 사회적 자본과의 연관성을 규명하고자 수행되었다. 자료는 경상남도에서 표준화사망비가 상대적으로 가장 높은 40개 읍, 면, 동에서 체계적 표본 추출로 선정된 220 가구의 구성원 중 가장 생월일이 빠른 19세 이상 성인을 대상으로 직접 면접 방법으로 수집하였다. 자료 수집 기간은 2010년, 2011년, 그리고 2012년의 8-10월이었으며, 최종 자료 분석 대상자는 8,800명이었다. 사회적 참여는 공식 집단 또는 비공식 집단에 참여하는 여부로, 신뢰수준은 영국의 국립 사회조사센터의 신뢰 설문 3 항목을 번역한 질문에 대한 긍정적 답변의 수로 구하였다. 자살생각은 ‘최근 1년 동안 죽고 싶다는 생각을 해본 적이 있습니까?’ 자살시도는 ‘최근 1년 동안 실제로 자살시도를 해 본 적이 있습니까?’ 라는 질문에 대한 ‘예’, ‘아니오’의 대답으로 구하였다. 인구사회학적 변수(성, 연령, 결혼상태, 직업, 식생활안정성), 주관적 건강수준, 그리고 건강행태변수(흡연, 음주, 운동)를 모두 통제한 로지스틱 회귀분석에서 사회적 참여와 신뢰수준은 자살생각 및 자살시도와 유의한 연관성이 있었다. 사회적 참여와 신뢰 변수는 모형의 적합도를 유의하게 개선하였다. 신뢰수준은 0인 경우를 기준으로 할 때 신뢰수준이 1인 경우 자살생각에 대한 교차비는 0.77(95%신뢰구간,0.63-0.94), 신뢰수준 3인 경우 자살생각에 대한 교차비는 0.69(95% 신뢰구간, 0.56-0.85)로 유의하였다. 사회적 참여는 둘 다 미참여하는 경우를 기준으로 할 때 비공식집단만 참여하는 경우 자살시도에 대한 교차비는 0.41(95% 신뢰구간, 0.21-0.80)로 유의하였다. 결론적으로 다른 변수와는 독립적으로 사회적 참여와 신뢰의 사회적 자본은 자살생각 또는 자살시도와 유의하게 연관되어 있었다. 사회적 자본이 자살행동을 예방할 수 있는지에 대해서는 더 많은 연구가 필요하다. Objectives: This study was performed to identify the associations of social capital with suicidal thoughts and attempts in Korean communities with poor health. Methods: We used the data from community health interviews conducted at 40 administrative sections (dong, eup, or myeon) with high mortality from August to October in 2010, 2011, and 2012 as part of the Health Plus Happiness Plus Projects in Gyeongsangnam-do Province. The 8,800 study subjects composed of 220 adults systematically sampled from each administrative section were asked if they had thought about suicide or had attempted suicide within 1 year. The social participation was measured with "participation in formal and/or informal group" and trust using responses to three questions about trust of others. Results: The prevalence of suicidal ideation and attempt within 1 year were 10.4% and 0.8%, respectively. The logistic regression analysis revealed that those who participated in only informal groups, or had highest trust level reported less suicidal ideation, or attempt after adjusting for socio-demographic factors (sex, age, marital status, occupation, and food affordability), self-rated health, and health behaviors (smoking, alcohol drinking, and exercise). Conclusions: This study suggested social capital such as social participation and trust was associated with less suicide ideation and attempt. More studies are warranted for the association of social capital with suicidal behavior.

보리 도정 시 발생되는 부산물(맥강)의 이용방안을 모색하기 위하여 5가지 품종의 쌀보리 보석찰(유색 찰성), 흰찰쌀(찰성), 다한(메성), 흑광(유색), 흑누리(유색)를 23%로 도정한 다음 입도별(<60 mesh(fraction Ⅰ), 60~100 mesh(fraction Ⅱ), >100 mesh(fraction Ⅲ)로 분획 후, 기능성분 함량에 대해 분석하였다. 베타글루칸의 함량은 모든 품종에서 fraction Ⅱ에서 가장 높게 나타났으며, 다한과 흑누리에서 높은 함량을 나타내었다. 아라비노자일란은 fraction Ⅲ에서 가장 낮은 함량을 보여 입도가 큰 분획물을 이용하는 것이 아라비노자일란 고함유 분획물을 얻을 수 있었다. 총 폴리페놀 및 플라보노이드는 모든 품종에서 fraction Ⅱ에서 가장 높은 함량을 나타내었으며, 항산화력과 라디칼 소거능 역시 fraction Ⅱ에서 가장 좋은 활성을 나타내어 비슷한 경향을 나타내었다. 분석한 모든 기능성분의 함량이 높았던 fraction Ⅱ는 보리의 겨층 부분과 배유층 부분이 적절히 혼입된 분획물로 판단되기 때문에 맥강의 기능성 식품 소재화를 위한 맥강을 선정할 때 fraction Ⅱ를 활용하는 것이 좋을 것으로 판단되었다. 이러한 결과는 보리 도정 부산물의 효율적인 이용을 위하여 품종 및 입도별 분류를 통해 유용성분이 고함유되어 있는 층을 얻고, 이를 활용한 식품 기능소재로서의 가능성을 확인하였다. This study evaluated the functional components of barley bran with different particle sizes and cultivars (Dahan, Hinchalssalbori, Heukgwang, Huknuri, and Boseokchal). Barley bran divided into fractions Ⅰ (<60 mesh), Ⅱ (60∼100 mesh), and Ⅲ (>100 mesh) was collected as pearling by-products produced by an industrial process consisting of consecutive barley pearlers. Total β-glucan contents of all cultivars were especially highest in fraction Ⅱ. Total arabinoxylan was the highest in barley bran from Boseokchal in fraction Ⅱ. Total polyphenol contents were the highest in bran from Boseokchal and Hinchalssal in fraction Ⅱ, and contents ranged of 5.61∼7.00 and 4.24∼6.58, respectively. Total flavonoid contents of all cultivars were especially highest in fraction Ⅱ. 2,2’-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities ranged from 2.78∼7.53 mg L-ascorbic acid (AA) eq/g and 2.24∼4.83 mg AA eq/g, respectively. ABTS and DPPH radical scavenging activities were the highest in barley bran from Dahan in fraction Ⅱ. In this study, fraction Ⅱ showed enriched functional components and has the best particle size range for enriched antioxidant activities. These results provide useful data for selection of appropriate cultivars and particle size of bran to achieve high quality barley processing.

Objective: This study was conducted to investigate the association between subjective distress symptoms and argon welding among workers in Gyeongnam Province shipyard. Method: 31 argon and 29 non-argon welding workers were selected as study subjects in order to measure concentrations of personal dust, welding fumes and other hazardous materials such as ZnO, Pb, Cr, FeO, MnO, Cu, Ni, TiO2, MgO, NO, NO2, O3, O2, CO2, CO and Ar. An interviewer-administered questionnaire survey was also performed on the same subjects. The items queried were as follows: age, height, weight, working duration, welding time, welding rod amounts used, drinking, smoking, and rate of subjective distress symptoms including headache and other symptoms such as fever, vomiting and nausea, metal fume fever, dizziness, tingling sensations, difficulty in breathing, memory loss, sleep disorders, emotional disturbance, hearing loss, hand tremors, visual impairment, neural abnormality, allergic reaction, runny nose and stuffiness, rhinitis, and suffocation. Statistical analysis was performed using SPSS software, version 18. Data are expressed as the mean ± SD. An χ2-test and a normality test using a Shapiro wilk test were performed for the above variables. Logistic regression analysis was also conducted to identify the factors that affect the total score for subjective distress symptoms. Result: An association was shown between welding type (argon or non-argon welding) and the total score for subjective distress symptoms. Among the rate of complaining of subjective distress symptoms, vomiting and nausea, difficulty breathing, and allergic reactions were all significantly higher in the argon welding group. Only the concentration of dust and welding fumes was shown to be distributed normally after natural log transformation. According to logistic regression analysis, the correlations of working duration and welding type (argon or non-argon) between the total score of subjective distress symptoms were found to be statistically significant (p=0.041, p=0.049, respectively). Conclusion: Our results suggest that argon welding could cause subjective distress symptoms in shipyard workers.

본 연구에서는 발아에 의한 팥의 기능성분 변화를 살펴보기 위하여 6일 동안 발아시키면서 유리형 및 결합형 폴리페놀, 플라보노이드, 페놀산 및 안토시아닌의 변화를 분석하였다. 유리형 폴리페놀 및 플라보노이드 함량은 발아기간이 증가함에 따라 각각 약 2.6배 및 5배 정도 증가하였으며, 결합형 폴리페놀 및 플라보노이드 함량은 발아 초기 감소하였다가 발아 3일 및 2일 이후 각각 증가하였다. 발아기간에 따른 구성 페놀산의 변화의 경우 ferulic acid, veratric acid, hesperidin, salicylic acid, naringenin 및 hesperidin과 총 페놀산은 유리형 및 결합형 페놀산 함량이 모두 증가하였지만, 안토시아닌 및 안토시아니딘은 침지 및 발아과정에서 손실되어 감소하였다. 본 연구 결과 팥을 발아시킬 경우 폴리페놀, 플라보노이드 및 페놀산 함량이 증가함에 따라 팥에 함유된 기능성분의 이용성을 증대시키기 위해서는 발아공정의 적용이 효과적이라고 판단된다. This study was performed to investigate the changes between free and bound forms of bioactive compounds in germinated adzuki bean. Adzuki bean was germinated at 25°C for 6 days, and then free and bound forms of bioactive compounds were extracted. Total free polyphenol and flavonoid contents in of raw adzuki bean increased from 0.91 mg/g and 0.60 mg/g in before germination to 2.37 mg/g and 3.03 mg/g in at 6 days after germination, respectively. Bound polyphenol, flavonoid, and phenolic acid contents also increased with increasing germination periods, whereas bound polyphenol and flavonoid contents slightly reduced in at 2 days after germination. The total phenolic acid contents, including ferulic acid, veratric acid, hesperidin, salicylic acid, naringenin, and hesperidin, increased during germination, and germination process can convert compounds to phenolic acid via anabolism and catabolism. Total anthocyanin and anthocyanidin contents of adzuki bean decreased during germination due to hydration by water during soaking or enzyme activation of anthocyanase during germination. These results suggest that the germination process increased utilization of functional compounds such as phenolic compound and isoflavones in black soybean.

The objective of this study was to investigate the non-thermal sterilization effect of methods such as high hydrostatic pressure (HHP) and UV-irradiation (specifically with regard to the storage stability and shelf-life of carrot juice. The microbial counts of the non-sterilized product increased from 5.51 to 7.34 log CFU/mL up to the fifth day, and then decreased to 5.46 log CFU/mL at six days. UV-irradiation was increased from 2.37 to 4.92 log CFU/mL. HHP was maintained under the 3 log CFU/mL. The pH of UV-irradiation and HHP was maintained withing the range of 6.29~6.30 and 6.20~6.22 during storage. However, the pH arising from non-sterilization decreased from 6.31 to 4.49. The color of non-sterilization changed significantly during storage, but UV-irradiation and HHP were similar during storage. The β- carotene content of non-sterilization was noted to have decreased from 269.45 to 65.19 μg/mL during storage. The UV- irradiation and HHP decreased from 263.46 and 268.35~281.16 μg/mL to 243.42 and 244.09~269.29 μg/mL, respectively. In conclusion, these findings suggest that HHP can be used for the pasteurization, or sterilization, of carrot juice and the optimal condition is two minutes.

기업의 지속가능전략 수립 시 환경적 전략 수립의 중요성이 강조됨에 따라 여러 타이어 제조업 체에서는 타이어 제조 시 환경영향요인 저감, 제품환경전략 수립을 위해 제품의 환경성을 정량적으로 평가하고 있다. 본 연구는 대표적인 환경성 평가 tool인 LCA(Life Cycle Assessment)와 Carbon Footprint 기법을 이용해 승용차용 타이어(PCR)과 트럭 버스용 타이어(TBR) 제품에 대한 환경영향을 정량적으로 분석하였다. Life cycle은 원료 취득 및 생산 단계, 원부자재 수송 단계, 제품 제조 단계, 제품 유통단계, 사용단계, 폐기 및 재활용 단계의 6단계로 설정해 LCA를 수행하였다. 분석 결과 타이어는 사용단계에서 가장 많은 환경영향이 발생하며, 구성부품 중에서는 tread에서 가장 환경 영향이 높은 것으로 분석되었다. 사례 분석을 통해 분석된 결과와 주요 타이어 제조사들의 LCA 및 탄소배출량 산정 수행 사례를 활용해 life cycle 각 단계별로 제품환경전략 수립의 방향성을 제시하였다. As the importance of environmental strategy is gaining weight, a number of tire manufacturers are quantifying the environmental aspect of a product in order to reduce the environmental impact of the product and devise an environmental strategy for the product. In this study, the environmental impact of Passenger Car Radial(PCR) tire and Truck Bus Radial(TBR) tire was quantified using Life Cycle Assessment(LCA) and Carbon Footprint which are the two of the main methods for assessing environmental impact. Life cycle in the LCA was divided into 6 categories: raw material extraction and production phase, transportation phase, product manufacturing phase, distribution phase, use phase, disposal and recycle phase. As a result, it was found that the use phase had the highest environmental impact, and the tread showed especially high environmental impact among all parts. This study suggests a direction for environmental strategy for a product in each phases of the LCA method by analyzing case studies and utilizing the LCA and Carbon Footprint assessment done by major tire manufacturers.
