The Korea Research Institute of Standards and Science has developed certified reference materials (concrete, soil, and metal radioactive liquid) for measuring gamma-emitting radionuclides to improve and maintain the quality assurance and quality control of the radioactivity measurement in decommissioning nuclear power plants. The raw materials that make up each CRM were mixed in an appropriate ratio with radionuclides. For certification and homogeneity assessment, 10 bottles were randomly selected, two sub-samples were collected from each bottle, and radionuclides were measured via HPGe gamma spectrometry. The results of the homogeneity tests using a one-way analysis of variance on the radionuclides in the CRMs fulfilled the requirements of ISO Guide 35. Coincidence summing and self-absorption correction were performed on measurement results by introducing the Monte Carlo efficiency transfer code and Monte Carlo N-Particle transport code. In concrete analysis, the reference values for five radionuclides (60Co, 241Am, 134Cs, and 137Cs) in the CRM were in the range of 15-40 Bq/kg, and the expanded uncertainty was within 10% (k = 2). In soil analysis, the reference values for the 137Cs and 60Co were 118.7 and 124.4 Bq/kg, and the expanded uncertainty was within 10% (k = 2). In metal radioactive liquid analysis, the reference values for 134Cs, 137Cs and 60Co in the CRM were in the range of 200-270 Bq/kg, and the expanded uncertainty was within 7% (k = 2).

Paddy fields provide important habitats for biodiversity conservation within the agricultural ecosystem. Their importance is gradually increasing as their ecological value is better understood. Benthic macroinvertebrates dominate paddy fields. They play an essential role in maintaining the biodiversity of paddy ecosystems. This study aimed to analyze characteristics of benthic macroinvertebrate communities and main environmental factors affecting the distribution of golden apple snails (Pomacea canaliculata). Results showed that the diversity index (H ′) of the benthic macroinvertebrate community was the highest at the Sangju site (St. 12) but the lowest at the Sancheong site (St. 18). Total Dissolved Solids (TDS), salinity, and Electrical Conductivity (EC) values were the highest in Gimhae and Yeongam based on Canonical Correspondence Analysis (CCA). Numbers of P. canaliculata (m-2) were relatively low in Gunsan and Iksan where water temperatures were high. Therefore, changes in geographical characteristics and environmental factors might affect the distribution of P. canaliculata and characteristics of benthic macroinvertebrate communities. Results of this study can be used as primary data for biodiversity conservation and ecosystem service evaluation in agroecosystems.

본 연구는 농식품 소비자패널을 대상으로 설문조사를 실시하여 소비자의 소비성향에 따른 저탄소인증농산물의 소비행태를 살펴본다. 소비자의 소비성향을 윤리적 소비성향과 합리적 소비성향으로 구분하여 집단을 구성하였고, 집단 간 소비행태 차이를 분석하였다. 윤리적 소비성향 집단과 합리적 소비성향 집단 간에 저탄소 농산물 인증제의 인지도, 탄소발생 감소를 위한 노력, 탄소중립 개념 인지도 및 저탄소인증농산물에 대한 구매의도 는 유의미한 차이가 있는 것으로 나타났다. 따라서 저탄소인증농산물의 소비활성화를 위해서 합리적 소비성향을 가진 소비자들의 저탄소인증농산물 구매를 유도할 수 있는 방안을 마련할 필요가 있다.

With the development of the economy and the continuous improvement of people’s living standards, consumers’ increasing demand for safe food has become an inevitable trend of social development. On the one hand, food safety is an urgent social problem needed to be solved in China. On the other hand, the food safety guarantee method based on a traceability system is popular. This paper systematically studies the influencing factors of consumers’ willingness to pay for the extra price of traceable pork in the Yanbian area through empirical analysis. The result showed that consumers’ attitude and subjective norms, and perceived behavior control, have significantly positively affect consumers’ willingness to pay the extra price. Meanwhile, consumers’ perceived risk of traceable pork significantly moderates the effect on consumers’ attitude and willingness to pay an extra price. The results can provide the corresponding reference for government agencies to formulate policies and provide valuable suggestions for enterprises to develop a pork traceability market to realize the development of a pork traceability system in the Yanbian area to ensure consumers’ food safety.

Statistical analysis for the 703 air purifiers certified by Korea Air Cleaning Association from 2003 to 2019 was performed. Sixty-one percent of the products had an area coverage of 15 m2~30 m2 and the median value of the total products was 37.6 m2. The number of certified products by the top five manufacturers was 325, which corresponds to 46.2% of the total products. The median value of the clean air delivery rate (CADR) of the 703 products was 4.8 m3/min but the number of air purifiers over the value increased to 62.5%~66.3% since 2018. The odor removal ratio showed a median of 86.0% which was higher than the certification criteria but had large differences in efficacy in the five test compounds. Removal efficiencies of each compound in terms of the median and ratio to the average value showed acetate > formaldehyde > toluene > ammonia > acetaldehyde in descending order with large variances. The median noise level average value from five positions of air purifiers was 47.7 dB(A). However the medians of the top position and the front, where purified air was vented out, were relatively higher in 49.8 dB(A) and 48.2 dB(A), respectively. Noise level ratio to noise criteria had a median value of 96.4%, which showed that most of the noise levels were distributed near the criteria limit. The probability of the noise level at 100% of the criteria was calculated ton 0.232, which indicated excess noise levels.

The experiment was undertaken to measure the potential impact of animal welfare on the pork quality under two different farming systems: C1 and C2, two conventional farms; W, an animal welfare farm. Ten pigs (Landrace × Yorkshire × Duroc) of live weight 110 kg were randomly selected from each treatment, and slaughtered under uniform conditions. The left loins were collected, and subsequently analyzed for proximate composition, meat quality traits, fatty acids, free amino acids, and antioxidative dipeptides. Pork from the welfare farm (W) had greater back-fat depth and fat content, but the values were not significantly different from C1 or C2. The W loins had significantly lower moisture contents and pH values compared to C1 or C2. The C2 loins showed highest contents of unsaturated fatty acids, whereas C1 had higher polyunsaturated fatty acids as compared to W. The treatments did not show any significant differences in the contents of free aspartic acid. Anserine (an antioxidant dipeptide) from the W loins was significantly lower than that from the conventional farms. The results indicate that pork quality characteristics from animal welfare-farmed pigs were not different from those of conventional farms. Therefore, it would be appropriate to evaluate the industrial value of animal welfare livestock only at the stage of pig production, rather than the meat quality of pork.

최근 할랄 시장의 규모는 매우 커지고 있으며, 전세계적으로 연구 및 발전되어야되는 가장 진보된 사업 중 하나로 주목 받고 있다. 이러한 배경으로 한국과 같은 무슬림 소수 국가들은 지역 경제를 활성화하기 위해 할랄 식품 산업에 진출하여 주도권을 잡으려는 계획을 진행하고 있다. 하지만 할랄 산업 연구에 대한 중요성과 학술 자원에 제한적인 가용성으로 인한 지식 격차는 여전히 남아 있는 실정이다. 본 연구는 할랄 식품 소비자의 구매행동을 고려하여 점점 증가하고 있는 할랄 시장 규모에 대한 정부의 진행방향에 도움을 줄 수 있는 할랄 연구의 기초 자료로 활용될 수 있다. 이를 위해 본 연구의 목적은 한국의 무슬림 소비자들 할랄 식품 구매 의도에 영향을 줄 수 있는 요인 조사를 목적으로 하였다. 본 연구를 위해 477명의 설문참여자를 통해 데이터를 수집하였으며, 한국의 행정구역에서 설문참여자를 모으기 위해 목적표본추출법이 사용 되었다. 이 연구의 가설 결과는 할랄 인증, 종교적 신념 및 할랄 브랜드 등 이 세가지 변수가 무슬림 소비자들 사이에서 할랄 구매 의도와 크게 관련이 있음을 확인하는 것이다. 본 연구의 결과는 제조업체들이 무슬림 소비자들의 할랄 구매 의도를 이해하는데 유용할 뿐만 아니라 소비자들이 일상 생활에서 할랄의 의미를 인지하는데 도움이 될 것으로 예상된다.

세척수에 포함된 무기물질의 함량이 먹는 물의 수질기준을 초과하여, 참외 GAP 인증을 받지 못하는 사례가 최근 들어 종종 발생하고 있다. 이에 농업현장에서는 껍질을 제거하여 먹는 참외의 소비특성을 감안하여 세척수 수질기준의 일부를 완화해 줄 것을 요청하고 있다. 이에, 본 연구에서는 성주 지역에서 2017-2019년 GAP 인증 참외의 세척에 이용되는 지하수 142건의 수질자료를 근거로 무기물질 4종(불소, 비소, 철, 망간)의 인체 위해성을 평가 하였다. 연구 결과, 성주 지역 GAP 참외의 세척에 사용 되는 지하수를 음용수 수준으로 섭취하는 우리나라 국민의 4종 무기물질에 대한 HQ는 모두 평균 0.10 이하로 안전한 수준이었다. 특히, 심미적 영향물질인 철, 망간의 경우 성주 지역 지하수를 음용수 수준으로 섭취하는 경우 HQ 가 평균 0.00. 과다노출군의 경우 0.01나타났는데, 일반 참외를 섭취하는 국민의 HQ(평균 0.01, 과다노출군 0.03)보다 낮은 수준이었다. 따라서, 성주 지역 지하수를 GAP 농산물의 세척에 활용하더라도 철, 망간을 포함한 4종 무기 물질이 인체에 미치는 영향은 미미할 것으로 생각된다.

The objective of this study was to comparatively analyze the vocalizations of farrowing sows and their piglets in a welfare certified farm and a conventional farm as they are useful parameters for animal welfare assessment. The conventional farm using the gestation stall, farrowing crate and nursery, grower‐finisher pigs were accommodated in small pens. On the other hand, in the welfare certified farm using the group feeding gestation sows, which allows them to turn around in the furrowing pens, unlike in the crates and nursery, grower‐finisher pigs were accommodated in large pens. Vocalization of farrowing sows and their piglets were recoded and acoustic parameters were analyzed. Eight vocalizations―screaming, fighting, playing, suckling competition, suckling, piglet call, frightened, and space competition―were recoded in the farrowing crate and classified; 4 ordinary and 4 non‐ordinary vocalizations were identified. However, frightened and space competition vocalizations were not detected in the farrowing pen. Screaming, fighting, playing, suckling competition, and suckling vocalizations were significantly (p<0.01) different in pitch, intensity and duration between the farrowing pen and the farrowing crate. Piglet call vocalization did not differ between the farrowing facilities. These findings will aid us in using the differences in vocalizations, under different conditions, as parameters of animal welfare assessment.

The objective of this study is to examine the effects of consumer beliefs regarding three food certifications on their behavioral intention and the behavioral intention biases to purchase (purchasing intention biases) certified agricultural products as predicted by a subjective probability model. The food certifications used for this study are ‘Organic food’, ‘Traceability system of food products,’ and ‘Hazard Analysis Critical Control Point (HACCP)’. Tofu (bean curd) was selected as being representative of agricultural food products, for the purposes of this study. In 2016, we surveyed 243 consumers regarding the strength of their belief regarding their prior beliefs relative to each certification, as well as the strength of their intention to purchase certified tofu based on their belief strengths for this study. The study resulted in the following findings: Firstly, consumers hold more than two different prior beliefs for each of the three certifications included in this study. Consumers’ prior beliefs regarding these certifications have an impact on their consideration as to whether they plan to buy those certified agricultural products. Secondly, consumers try to persuade themselves to ensure that their particular belief about the product’s certification could lead to a purchasing decision regarding that agricultural product

본 연구는 상추와 오이의 GAP 인증 및 미인증 농가를 대상으로 토양, 용수, 작물 (상추, 오이), 장갑, 포장재 (비닐)에 대한 미생물 오염도를 비교·평가하고 농가의 위생관리 실태를 조사하여 GAP 인증 농가에 대한 미생물학적 안전성 강화를 위한 자료로 활용하고자 하였다. 미생물 오염도 조사 결과 상추 농장의 경우 위생지표세균 오염도는 GAP 인증 농가가 미인증 농가 보다 조금 낮거나 유사하였고, 병원성미생물인 S. aureus와 B. cereus는 GAP 인증 농가의 토양과 용수에서 미인증 농가 보다 높게 검출되었다. 오이농장은 토양의 대장균군과 B. cereus, 장갑의 일반세균 및 대장균군 오염도가 GAP 미인증 농가보다 GAP인증 농가에서 높았고, 그 외에는 GAP 인증 농가와 미인증 농가가 유사한 오염도를 나타내었다. 전체적으로 결과를 비교했을 때 GAP 인증 농가와 미인증 농가의 미생물 오염도 수준이 크게 차이가 나지 않는 것으로 확인되어 GAP를 인증 받았음에도 불구하고 미생물에 대한 관리는 미흡한 것으로 나타났다. 농가의 위생관리 실태 조사 결과에서는 GAP 인증 농가가 미인증 농가보다는 미생물 오염을 방지하기 위한 노력들을 하고 있는 것으로 확인되었으나, GAP 인증 및 미인증 농가 모두 농업용수의 관리와 작업 시 사용되는 작업자의 장갑 관리에 있어서는 미흡한 것으로 확인되었다. 이상의 연구결과는 농산물의 미생물 오염방지에 대한 방안을 제시하고 GAP 인증을 개선하는데 기초자료로 활용될 수 있을 것으로 판단된다.

This study examines the effects of consumer beliefs for food certifications on the behavioral intentions and the behavioral intention biases to purchase the certified seafoods by a subjective probability model which is on the basis of the mathematical probability model and the covariance model. The food certifications used on this study are‘Organic foods’,‘Traceability system of food products’and ‘. HACCP’. The representative foods of fishery products on this study is seasoned laver. The current study showed the following results. First, consumers have more than two different beliefs each for all certifications which are the subjects of this study. The beliefs of the certifications have an impact on the consumers when they consider to buy the certified seafood products. Second, consumers try to persuade by themselves to ensure that their particular belief about the certification could lead to a purchase the seafood products. Consumer beliefs of the“environmentally friendly production”on the organic foods certification is an important factor as much as the“guarantee of food safety”belief making a positive purchasing behavior intentions(PBI) bias for the organic seafood products. Consumers also have a positive PBI bias for certified seafood products in all certifications as long as a certification is considered to “guarantee the transparency of the food distribution process”as its belief.‘Traceability system’was the only one which didn’t generate a positive PBI bias from the belief of“guarantee of food safety”out of three certifications.

The aim of this study is to analyze error cases induced during the proficiency test of certified odor measurement agencies. In the case of the homogeneity test performed in three panel groups, the geometric mean dilution factor of the site boundary PTMs(proficiency testing materials) was 1.4 ± 0.2, 1.7 ± 0.2, 1.8 ± 0.1 and that of the outlet PTMs was 3.7 ± 0.2, 3.7 ± 0.3, 3.7 ± 0.3, respectively. In the case of the stability test for 72 h, the geometric mean dilution factor of the site boundary PTMs was 1.6 ± 0.1 and that of the outlet PTMs was 3.6 ± 0.1. Among error cases induced during the proficiency test of certified odor measurement agencies, the proportion of error cases was in the order of case II(discontinuance of estimation)(40.0%) > case I(error on estimation procedure by panelist)(33.3%) > case III(miswriting of estimation result)(13.3%) > case IV(miswriting of dilution factor) and V(writing of wrong estimation result)(6.7%). Therefore, it seems likely that additional education related to error cases II and I is required.

서론 : 현재 우리나라는 국립재활원, 송파구청, 몇몇 개인 운전학원과 연계된 장애인 단체 그리고 최근 개원한 대구대학교의 운전재활센터만이 장애인들이 운전재활 교육을 받을 수 있는 곳이다. 또한 장애인에게 운전재활을 교육할 수 있는 전문 인력이 우선 필요한데, 이들을 양성할 수 있는 조직적이고 전문적인 프로그램이 아직 준비되지 못한 것이 부인할 수 없는 현실이다. 따라서 본 연구에서는 미국의 예를 들어 차후 한국에서 장애인운전재활 전문가 양성을 위한 제도를 만들고자 할 때 이에 대한 기초지식을 제공하려고 하였다. 본론 : 미국 운전재활전문가와 운전재활 전문가 자격증에 관하여 중추적인 역할을 하는 ADED에 대한 간단한 역사, 시험응시자격, 시험규정, 응시절차, 출제내용 설명, 시험응시에 관한 유의사항, 그리고 자격증 취득 후에 그 자격증을 지속적으로 유지하 는 방법들에 대하여 기술하였다. 미국은 운전재활전문가가 되기 위해 이처럼 복잡하고 까다로운 자격요건을 요구하여 전문가 로서의 전문성과 자질을 지속적으로 유지하도록 하고 있으며, 또한 장애를 가진 사람이라 할지라도 자가운전의 중요성을 인식하고 장애인들에게 진정한 사회복귀와 삶의 질을 향상 시켜주는 제도의 발전에 노력을 기울이고 있다. 결론 : 앞으로 운전재활 전문가 양성방안을 마련해야 할 우리나라로서는 미국 운전재활전문가협회와 운전재활전문가 자격증 제도에 대한 전반적인 내용을 알아봄으로써 우리나라의 장애인 운전재활과 운전재활전문가에 관심이 있는 사람들에게 유용 한 정보가 될 것이다.
