When producing rice products, it is very important to select suitable raw materials. Therefore, in this study, the quality characteristics of 16 rice cultivars were quantified to determine the criteria for evaluating the machinability of raw rice. The L value, which can affect the color of porridge prepared from rice, was the greatest for Hwaseonchalbyeo (84.17). The water-binding capacity, related to water interaction, was high in Hyangcheola (113.2%), and water solubility was high in Shingil (22.3%). Dodamssal (42.3%, 70.7 RVU) and Hwaseonchalbyeo (4.7%, 27.8 RVU) showed lower final viscosity compared to the cultivars in which the amylose content was medium groups (16.4~21.2%, 173.6~277.2 RVU). Specifically, cultivars with high or low amylose content had a low viscosity. The characteristics of the distribution of raw rice quality data were confirmed through 11 histograms. Furthermore, amylose content vs. water solubility, water solubility vs. peak viscosity, and peak viscosity vs. final viscosity showed high correlations (r=0.542, -0.569, and 0.836 respectively, p<0.01), and clear cultivar discrimination by the standard error of the mean (0.765~10.811). In conclusion, amylose content, water solubility, and peak viscosity were considered the most suitable characteristics for the quality evaluation of raw rice.

In this study, the product characteristics and physicochemical properties were investigated through collection of commercial porridge. The addition rate of grain raw materials was about 6.5~11.75%, glutinous rice was added at a rate of about 23~60% to improve the viscosity and various other food additives were used. The moisture content characteristics varied among the products. The rotational viscosity of CP (Commercial Porridge)4 was the highest at 39,054 cP, while the flow viscosity of CP3 was least at 4.80 cm/30 seconds. The starch content differed among the products in the range of total starch 6.96~8.08%, amylose 1.41~2.61%, total sugar 6.55~12.81% and reducing sugar 0.50~0.99%. Particularly, total sugar showed a very high correlation (-0.920) while rotational viscosity and color value (b) showed significant correlation with most of the properties i.e. moisture, solids content etc. There was a rapid increase in the reactivity of starch degrading enzyme at the early stage of the reaction which gradually decreased with time. The physicochemical characteristics of commercial porridge presented in this study could be expected to increase the industrial use value of the related research because it considers the quality of the currently commercialized porridge for the future selection of suitable porridge raw materials.

This study was conducted to secure basic information for corn processing by comparing the quality characteristics according to maize cultivars and kernel types (dent, intermediate, flint-like). As a result of analyzing 15 cultivars, a range of measurements were observed: 100-kernel weight, 22.89~35.63 g; moisture, 7.57~8.42%; crude protein, 8.46~11.45%; crude lipids, 3.26~4.83%; Hunter's L-value, 83.70~86.79; a-value, 2.61~5.49; b-value, 22.01~28.15; and total carotenoids, 6.74~17.07 ㎍/g. Significance among the cultivars was shown in all quality characteristics (p<0.001), but the significance among the kernel types was found only in crude protein (p<0.005), crude fat (p<0.001), and Hunter's L-value (p<0.05). The hardness of maize was decreased proportionally to the soaking time for all maize cultivars (p<0.001). In particular, with the same soaking time for different kernel types, the hardness difference was shown in the order of flint-like > dent ≒ intermediate. It was confirmed that the decrease in the hardness of flint-like kernel of close to that of hard-type starch was slowed compare dent and intermediate kernels. So it is expected the some characteristic of kernel types will contribute to the appropriate customized use of the developed cultivars.

Objective : Associations of vascular risk/disease or apolipoprotein E ${\varepsilon}4$(APOE4) with geriatric depression has been unclear at a population level. This study aimed to evaluate whether there would be interactions of vascular risk/disease and APOE4 on depression in a Korean elderly population. Methods : 732 community residents aged 65 or over were assessed for depression(GMS), information on vascular risk/disease(reported stroke, transient ishemic attack, heart disease, hypertension, diabetes, smoking), examinations for vascular risk/disease(blood pressure, blood tests for glucose and lipid profiles, body size), APOE genotypes, demographic characteristics(age, gender, education), physical health, and cognitive function(MMSE). Results : Previous stroke and lower level of high density lipoprotein(HDL) cholesterol were significantly associated with geriatric depression independent of demographic characteristics, physical illnesses, and cognitive function. These associations were statistically significant only in those with APOE4, although the interaction terms didn't reach to statistical significance. Conclusion : Associations between vascular risk/disease and geriatric depression might be more prominent in those with APOE4. However further research would be needed to clarify this issue.

The purpose of this study was to investigate the Maillard reaction-related physicochemical properties of three maize varieties (Kwangpyeongok, Sinhwangok2ho and Gangdaok) after roasting them for different times (0, 15, 25, 40, and 55 minutes). The Maillard reaction is a non-enzymatic browning reaction involving reducing sugars and amino compounds. The content of reducing sugar, the causative agent of the Maillard reaction, decreased as roasting time increased. Gangdaok showed the lowest reducing sugar content of 1.04 mg/g after 55 minutes of roasting. In the elapsed roasting time, chromaticity 'L' and 'b' values decreased. At 55 minutes of roasting, wherein the Maillard reaction occurred most actively, Gangdaok showed the lowest 'L' value of 56.37 and the highest 'a' value of 7.60. Gangdaok had superior conditions for inducing the Maillard reaction compared to other varieties, and it is consider that 'flint-type', an endosperm characteristic, may have been the influencing agent. This study detected a total of 52 types of volatile aroma compounds (VACs), of which 28 were produced after roasting. Of the total VACs detected, 2-Formyl-5-methylfuran and 2-Furancarboxaldehyde accounted for 43.8~45.5% and have been confirmed to be the major VACs present in roasted maize. Most of the correlations between the Maillard reaction-related characteristics showed high correlation coefficients.

중등학교 독서 문화 비판 박혜영이 연구의 목적은 중등학교 독서 문화에 나타난 문제점을 비판적 관점에서 살펴보고, 문제점에 대한 해결 방법을 생각해보는데 있다. 먼저 중등학교 독서 문화 비판의 객관성 확보를 위해 2004년부터 200년까지 국가 차원에서 이루어진 대단위 독서 실태 조사들을 정리·분석해보고, 그에 대한의문점으로부터 중등학교 독서 문화의 문제점을 다음의 다섯 가지를 도출하여 살펴보았다. 첫째, 책을 읽지 않는 학생들이 가장 심각한 문제이다. 부족한 독서 시간을 위해 학교 교과과정 내에 독서 시간을 확보하는 노력이 필요하고, 독서 자체를 즐길 수 있는 내적 독서 동기 유발에 대한 연구가 시급하다. 둘째, 학생들의 독서 내용이 건전하지 못하다. 인터넷 소설류를 즐겨 읽거나 학습 독서에만 치중하기 때문에 다양하고 폭넓은 독서가 되지 못하고 있다. 셋째, 독서 지도의 중요성을 인식하고 있으나 학교 독서 지도의 양과 질이 모두 부족한 것으로 보인다. 독사 지도에 대한 체계적인 연수가 교사들에게 필요하다. 넷째, 학부모와 교사들은 독서의 중요성에 공감하면서도 학생들에게 스스로 독서 모델이 되어주지 못하고 있다. 학생들이 닮고 배울 독서 모델이 없다. 다섯째, 중등학교 독서 문화의 중심에 있어야 할 학교도서관이 제 역할을 다하지 못하고 있다. 외형적으로는 진화되었지만, 실질적인 관리와 운영의 주체를 확보하고 있지 못하다. 위와 같은 문제를 인식하고, 중등학교 독서 문화 비판에서 나아가 바람직한 독서문화를 이끌기 위한 구체적이고 실천적인 대안들이 정교하게 제기되어야 할 것이다. The purpose of the study was closely to examine actual reading condition and problems in korean secondary school. In actual reading condition at secondary school, stakeholders(students, teachers, parents, administration) recognize that student do not read, do not love reading and do not have habits of reading. Moreover, the more time is running, the more the reading ratio is decreasing. The Korean Reading Culture at Secondary school has five problems. : students who do not read, students who read harmful books, schools which provide no instruction about reading, students who can not look for their models of reading, and school libraries which are rarely managed. However, naturally we observed a few successful facts, school which has good reading programs, a single teacher who has a good school reading research, the school district which starts a reading movement and effectively use the internet in reading. These are just a few cases. The majority of schools aren`t. In conclusion, this study serves as searching for problem solving in the Korean reading culture at secondary school.

원료 품종별 쌀죽의 품질 특성 비교

The effect of 16 cultivars on the quality of the rice porridge was investigated. The 'Geunnun' had the highest water absorption rate, but the 'Segyejinmi' yield (w/w) was the highest. The total sugar content of the rice porridge was 0.29~8.10%, showing significant variation among the cultivars. High amylose 'Dodamssal' and 'Hwaseonchalbyeo' glutinous rice displayed rotational viscosities of <20,000 cP. Rotational viscosities for boiled rice cultivars were 30,000~40,000 cP, representing an intermediate level, and the rotational viscosities of 'Geonyang2' and 'Hanareum4' were over 50,000 cP. These results suggest that the viscosity of rice porridge varies significantly among raw material cultivars. Among other variables affecting the texture profile of rice porridge, there were significant differences in hardness and gumminess among the cultivars. As a raw material, 'Baekokchal', a kind of glutinous rice, is known to be whiter than the non-glutinous rice, but after processing to porridge, it showed the lowest L value (71.1). Starch degrading enzyme activity was not significant in most types of rice porridges within 30 or 60 minutes. Therefore, enzymatic starch degradation is thought to be completed within 30 minutes. Among the tested raw materials, 'Miho' was 73.5 ㎍/mg, indicating the best digestibility in vitro.

박혜영,박상민,이기철,권오상,유순주,김신조,Park, Hye-Young,Park, Sang-Min,Lee, Ki-Cheol,Kwon, Oh-Sang,Yu, Soon-Ju,Kim, Shin-Jo 대한환경공학회 2011 대한환경공학회지 Vol.33 No.3

우리나라의 공공하수처리시설은 생물학적 인 제거공정을 운전하고 있으나, '12년부터 지역구분(I, II, III)에 따라 각각 0.2, 0.3 및 0.5 mg/L로 강화되는 방류수수질기준을 준수하기 위해서는 화학물질을 이용한 추가적인 인 처리시설을 적용할 필요성이 대두되었다. 강화된 총인의 수질기준을 만족하기 위해 적용된 물리화학적 처리기술 성능의 구체적인 운영자료 구축을 위하여, 화학적 응집제 사용 중인 인 처리시설 중 모범적으로 가동하고 있는 국내 시설의 운영 데이터를 분석하여 처리성능을 평가하였다. 또한, jar 테스트를 이용해 물리화학적 인 제거공정 적용 시 최적 응집제 주입율 도출, 인 제거 및 슬러지 발생특성을 관찰하고 약품비용과 슬러지 발생증가량을 산정하여 실처리장에 응집제 적용 시 예상되는 경제성 분석을 하였다. 활성슬러지를 이용한 jar 테스트 결과, 0.5와 0.2 mg/L 이하의 총인 농도를 달성하기 위해 필요한 최소한의 응집제(황산알루미늄, 폴리염화알루미늄)의 주입농도는 각각 25와 30 mg/L (as $Al_2O_3$)이며, 2차 처리수의 경우에는 동일한 총인 농도를 달성하기 위해 요구되는 응집제 주입농도가 활성슬러지에 비해 약 1/12~1/3 수준으로 감소하였다. jar 테스트 결과, 활성슬러지에 응집제를 주입할 경우에 고형물 농도가 약 10~11%가 증가할 것으로 예측되었다. 한편, 활성슬러지에 응집제를 주입하는 경우의 응집제(황산알루미늄) 구입비는 2차 처리수에 주입하는 경우에 비해 약 4~10배 정도가 증가할 것으로 산정되었다. 또한, 슬러지 발생량은 약 4~10배 정도 증가할 것으로 예측되었다. Wastewater treatment plants (WWTPs) are required to meet the reinforced discharge standards which are differentiated as 0.2, 0.3 and 0.5 mg-TP/L for the district I, II and III, respectively. Although most of WWTPs are operating advanced biological phosphorus removal system, the supplementary phosphorus treatment facility using chemical addition should be required almost at all WWTPs. Therefore, water quality data from several exemplary full-scale plants operating phosphorus treatment process were analyzed to evaluate the reliability of removal performance. Additionally, a series of jar tests were conducted to find optimal coagulants dose for phosphorus removal by chemical precipitation and to describe characteristics of the reaction and sludge production. Chemical costs and the increasing sludge volume in physicochemical phosphorus removal process were estimated based on the results of jar tests. The minimum coagulant (aluminium sulfate and poly aluminium chloride) doses to keep TP concentration below 0.5 and 0.2 mg/L were around 25 and 30 mg/L (as $Al_2O_3$), respectively, in the mixed liquor of activated sludge. In the tertiary treatment facility, relatively lower coagulant doses of 1/12~1/3 the minimum doses for activated sludge were required to achieve the same TP concentrations of 0.2~0.5 mg/L. Increase in suspended solids concentration due to chemical precipitates in mixed liquor was estimated at 10~11%, compared to the concentration without chemical addition. When coagulant was added into mixed liquor, chemical (aluminium sulfate) cost was estimated to be 4~10 times higher than in secondary effluent coagulation/separation process. Sludge production to be wasted was also 4~10 times higher than secondary effluent coagulation/separation process.

The purpose of this study was to derive the conditions for manufacturing rice porridge with optimum properties after reheating. The characteristics of rice porridge according to the soaking time, water addition rate, heating temperature, heating time, and cooling conditions were compared using the 'Samkwang' cultivar. In Step I, as the heating temperature increased, the weight change decreased and the viscosity increased, and the temperature known as the main factor of the gelatinization also appeared to affect the viscosity increase. In Step II, the viscosity and the texture properties was not significantly different as the soaking time was reduced, and 10 minutes was suitable because of due to the shortening effect of the total process time. In Step III, the residual heat was lowered by cooling after the rice porridge production, so the viscosity could be greatly reduced. Also, it was confirmed that the water addition rate of 900% and the heating temperature of 15 minutes were optimal manufacturing conditions. The next study will investigate the porridge processability of rice cultivars using these results.
