        Cooking, especially meat and fish grilling, is one of the representative sources of indoor and outdoor particulate matter (PM). Most of PM emitted from cooking is ultrafine dust (PM2.5). Since odorous organic acids, aldehydes, and volatile organic compounds are absorbed by PM and discharged, restaurants and food service industries are major sources of odorous PM emission that cause odor nuisance complaints in cities. PM emitted from cooking also contains polycyclic aromatic hydrocarbons (PAHs), which are carcinogens. In this paper, the domestic PM emission status of biomass combustion, especially meat and fish grilling, was analyzed temporally and spatially. The results of previous studies on PM emission concentrations, emission rates, emission factors and their compositions from cooking were comprehensively summarized. In addition, the effects of food ingredient types, cooking methods, seasoning and oil addition and fuel types on the PM emission were reviewed. Much more PM was produced when cooking with charcoal rather than electricity or gas. The higher the fat content of food ingredients such as intestines, the higher the PM emission concentration and emission rate. There was a difference in the PM emissions depending on the cooking oil types, and the PM emission concentration was high when olive oil or corn oil was used. It is necessary to accumulate more information through followup studies on the emission concentrations, emission factors and properties of PM emitted from cooking activities. This information can be used for controlling odorous PM in restaurants and food service industries, and predicting the impacts of odorous PM on air quality and human health.

        This study investigated the effect of cooking class on improvement of eating behaviors and satisfaction with cooking activities in children. The questionnaires developed for this study were distributed to 380 mothers during June to August, 2011. A total of 286 questionnaires were used for analysis (81.7%), and frequency analysis, ANOVA, and χ2-test were completed using SPSS (version 14.0) software. The children with cooking experience (52.7%) showed more improvement of eating habits than children with no cooking experience (36.4%). Both types of children showed an ‘unbalanced diet’ with respect to eating habits. The overall satisfaction level was an average of 3.84±0.62. The effects after cooking activities varied for different aspects of improvement of eating habits: ‘Correcting unbalanced diet’ was 4.26±0.66, ‘nutrition knowledge’ was 4.06±0.70, ‘dining etiquette’ was 4.09±0.63, and ‘regular meals’ was 4.15±0.73. There was a significant difference between genders with regards to correcting unbalanced diet with vegetables (p<0.01). Ages from 10 to 12 were able to improve unbalanced diet with ‘grains’ (p<0.001), while ‘Kimchi’ (p<0.05) and ‘paste’ for ages from 10 to 12. In conclusion, cooking activities are regarded as effective in correcting unbalanced diet and eliciting positive changes in eating behavior.

        This study analyzed Korean traditional foods and western foods in the field of 'dietary life' in Practical Arts curriculums, and developed the fusion-food cooking activity program for elementary school students. Firstly, potatoes, dumplings coated with bean paste, simple side dishes are discussed in the first curriculum. The second curriculum discussed only traditional foods and the third curriculum considered more traditional foods than western foods including bread. From the fourth curriculum to the sixth, traditional foods were mainly discussed and both traditional foods and western foods were mentioned evenly in the seventh and revised 2007's curriculum. Secondly, this study developed 'fusion-food cooking activity' program which helps students not only to learn the meaning, kinds, history, and related customs of Korean traditional foods; kimchi, Korean pizza, rice cake, but also to learn and practice cooking fusion-foods covering traditional foods.In conclusion, it can be assumed that the 'fusion-food cooking activity' program developed in this study improves interest in Korean traditional foods amongst elementary school students, and helps students to understand the reputation and value of traditional foods. Therefore fusion-foods cooking activity containing traditional foods which are not discussed in this study should be studied and developed more in the future.

        ◉ 목적: 본 연구의 목적은 요리활동의 적용이 감각방어 아동의 감각처리능력 및 문제행동에 미치는 영향을 알아보기 위한 것이다. ◉ 연구방법: 감각력 평가(Sensory profile ; SP) 검사를 통하여 감각처리에 문제를 가진 3명의 아동을 대상으로 부모의 동의를 얻어 12주 동안 각 아동마다 10회에 걸친 요리치료를 실시하였다. 아동마다 연구자 1명씩 개입하여 약 30분~60분씩 요리활동을 하였고, 치료 전후 평가는 감각력 평가(Sensory profile ; SP)와 문제행동체크리스트(Child Behavior Checklist ; CBCL)를 사용하였다. ◉ 결과: 각 아동마다 감각력 평가(Sensory profile ; SP)와 문제행동체크리스트(Child Be havior Checklist ; CBCL)평가 결과, 3명의 아동 모두 긍정적 효과를 보였다. A아동은 감각력 평가(Sensory profile ; SP) 검사결과 총점 235점에서 263점으로 점수가 변화하였고, 문제행동체크리스트(Child Behavior Checklist ; CBCL) 평가 결과 총점 127점에서 106점으로 감소하였다. B아동은 감각력 평가(Sensory profile ; SP) 검사결과 총점 298점에서 308점으로 증가하였고, 문제행동체크리스트(Child Behavior Checklist ; CBCL) 평가 결과 총점 107점에서 103점으로 점수가 변화하였다. C아동은 감각력 평가(Sensory profile ; SP) 검사결과 총점 287점에서 302점으로 점수가 변화하였고, 문제행동체크리스트(Child Behavior Checklist ; CBCL)평가 결과 총점 110점에서 96점으로 점수가 감소하였다. ◉ 결론: 감각방어를 가진 아동에게 요리활동을 적용하였을 때, 감각처리능력을 향상시키고, 문제행동을 감소시키는 효과가 나타났다. 이러한 결과를 기초로 대상자의수를 늘리고 장기간에 걸쳐 아동의 변화를 확인할 수 있는 요리활동 연구가 지속적으로 필요하다고 사료된다.

        Asthmatics are more susceptible to fine particulate matters (PM2.5), compared to the general population. It has been reported that indoor PM2.5 is mainly generated by combustion of fossil fuels, meat or fish In particular, asthmatics are known to be more susceptible to indoor PM2.5 because 65 ∼ 95% of child or adult asthmatics stay inside the house. Thus, understanding the association between indoor activity patterns and variations in indoor PM2.5 levels is important. The purpose of this study is to determine the distribution of hourly indoor PM2.5 concentrations in asthmatics’ homes, and to evaluate its association with pan-frying cooking activity patterns, the most common PM2.5 emission related activity. From November 2017 to February 2018, real-time PM2.5 concentrations were measured in the living room of each asthmatic’s house (n = 35) for three weeks at 1 minute intervals. At the same time, self-reported daily activity patterns, hourly proportion (%) of cooking activities, were also recorded every hour over three weeks for each patient. In this study, we provided quantitative evidence that the distribution patterns of indoor hourly PM2.5 concentrations were associated with indoor cooking activities, especially in the homes of adult asthmatics. In addition, we observed that PM2.5 emitted by pan-frying could maintain even over up to 2 hour lagtime.

        The purpose of this study was to evaluate the physicochemical characteristic of the cooked rice added with glutinous and non-glutinous sorghum. The sorghum cultivars were Sorghum bicolor L. Moench cv. Hwanggeumchal, Nampungchal (glutinous), and Donganme (nonglutinous), and rice cultivar was Ilpum rice. The cooking properties and pasting characteristics of cooking rice adding with sorghum according to varieties and different addition rates evaluated. The cooking properties and pasting characteristics had significant changes with the varieties and different addition rates of sorghum. With increased addition rates of sorghum, the pasting temperature, peak viscosity, trough viscosity, breakdown viscosity, and final viscosity were decreased. With increased addition rates of sorghum, the total polyphenol and flavonoid contents before and after cooked rice were increased. Total polyphenol contents of 30% addition rates before cooking rice with Hwanggeumchal, Nampungchal, and Donganme sorghum were 1,693.30, 1,890.98 and 2,386.11 μg/g sample, whereas those after cooking rice with sorghum were 1,189.28, 1,190.42 and 1,397.87 μg/g sample, respectively. The high level of DPPH radical scavenging activity before and after cooking rice with sorghum were 126.29 and 70.58 mg TE/100g sample in the Donganme in 30% addition rates. Also, ABTS radical scavenging activity was 135.56 and 83.12 mg TE/100g sample, respectively. The results of this study show that the addition of sorghum can make cooked rice improved antioxidant activity.
