Chemical compositions of Japonica and J/Indica brown rices were compared. No significant differences were noted for amino acid composition of brown rice among varieties. The first and second limiting amino acids of brown rice were lysine and isoleucine, respectively. The major fatty acids of brown rice were palmitic, oleic and linoleic acid, which comprised of 96% of total fatty acid. The contents of saturated fatty acids were lower in Japonica varieties. The average value of calcium over phosphorus was 0.052.

This experiment was conducted in order to utilize whey, by-product obtained to cheese making, as substrate for alcohol fermentation. The strain used in this experiment, lactase fermenting yeast, was isolated from cheese whey and was identified as Candida pseudotropicalis. The Alcohol productivity with isolated strain was maximized after 4 days of cultivation at 30℃, pH 5.0 in whey medium containing 10% lactase and alcohol content in cultured medium was 4.8%. The alcohol production was increased a little by addition of 0.5% yeast extract. Fermentation efficiency was high at low concentration of lactose.

송보현,김동연 한국농화학회 1983 Applied Biological Chemistry (Appl Biol Chem) Vol.26 No.3

As an improved way of preserving astringent persimmons, dipping storage in various brines was investigated. Samples of Bongok and Sagok varieties of persimmon were dipped either without packing or after packed in polyethylene(PE)film in eight different solutions containing different amount of water, table salt, and sweeteners for one to five months. Contents of pectin, tannin, salt, reducing sugar, acids, ascorbic acid, and hardness, color, and flavor characteristics were analyzed at time intervals during the storage. Hardness of persimmons dropped during the first 30 days of dipping and rised till 60 days and dropped again. Pectin content decreased gradually from the beginning of storage. Total acid reduced till 60 storage days and maintained the same level till 90 days and increased again thereafter. Reducing sugar and ascorbic acid decreased for the storage period. Soluble tannin rapidly decreased till 60 days and then slightly increased and again decreased after 90 days. Salt concentrations in persimmon tissues after five months were 0.81∼0.83% in 1% solution, 2.52∼2.62% in 3% solution and 0.15% in the P.E. film packed ones. Between samples of under-ripened and fully ripened, the ripened samples had better quality after the storage. The taste of persimmons dipped in salt solutions was good in the order of 1%-solution$gt;3%-solution$gt;5%-solution of salt. The best qualities in color, taste, and hardness were obtained in Sagok samples stored in 1% salt solution among bare-fruit dipping and Bongok samples dipped after P.E. packing in 3% salt solution.

세계 주요 도시 기후변화 대응 계획의 텍스트 분석

송보현(Song, Bo Hyun),정혜진(Jung, Hye-jin),김규빈(Kim, Kyubin) 에너지기후변화교육학회 2021 에너지기후변화교육 Vol.11 No.2

기후변화 대응의 실질적인 이행 주체인 지방 정부, 그리고 막대한 에너지 소비 지역인 도시의 기후변화 대응이 매우 중요한 시기이다. 따라서, 세계 주요 도시에서 발행한 기후변화대응계획의 내용을 살펴보는 것은 지자체단위에서 감축 목표와 수단을 결정하고 실천하고자 할 때 도움을 줄 수 있다. 우리는 세계적인 온실가스 배출 도시에서 발행한 기후변화 대응 보고서의 텍스트를 일정한 방법론에 따라 분석하였다. 분석의 결과로서 감축 목표 경로, 감축 이행 수단, 그리고 감축 수단별 기여도를 도출할 수 있었고, 경향성 또한 확인할 수 있었다. 우리는 도시별로 특징적인 감축 계획의 방향과 차이점을 확인하기 위하여 의미 네트워크를 분석하였고, 특정 도시의 감축 계획을 자세하게 살펴보고, 시사점을 도출할 수 있었다. 다만, 많은 도시에서 감축량과 목표를 제시하였지만, 아직까지는 실천계획과 성과 등이 구체적이지 않아 이에 대한 개선과 모니터링이 필요하다는 것도 확인하였다. With cities accounting for a significant proportion of global greenhouse gas emissions, there has been an increased emphasis on the role of urban governments in enabling climate action on the local level. This study reviews the climate action plans of 30 key global cities and can help local leaders establish carbon emission reduction goals and implement measures to realize them. We conducted a textual analysis to map the general trends of the cities’ action plans. Our study also examines emission reduction pathways, proposed measures to achieve reduction and their anticipated contributions towards the reduction target. We conclude with semantic network analysis to identify unique reduction methods and understand differences between the various action plans. Our study reveals that while most cities present emission reduction targets, many propose emission reduction measures and actions that lack specificity and thus require improvement and continued monitoring.

매실의 野生酵母를 발효 실험을 통하여 酵母의 同定, 酒精, Fusel oil 및 香氣 成分을 分析한 結果는 다음과 같다. 매실에서 발견된 野生酵母는 Saccharomyce cervisiaeSP. 5종 Pichti속 3종. Torulopsis 2종을 同定하였다. 酒精 生成力은 일발연 1호가 16%였으며 野生 酵母Ⅰ,Ⅱ.Ⅲ,Ⅳ는 각각 15.2%, 14.1%, 7.64% 및 13.5%였다. Fusel oil 生命力은 일발연 1호가 2.7%, 396호가 2.6%였으며 野生 酵母 Ⅰ,Ⅱ,Ⅲ,Ⅳ는 각각 0.5%, 0.3%, 0.3% 및 0.5%로 나타 香氣 成分은 일반연1호, 396호, 野生 酵母Ⅰ은 비슷하였으며 野生 酵母Ⅱ, Ⅲ, Ⅳ는 香氣 成分이 많은 것으로 나타났다. This study was conducted to evaluate the alcohols and flavors through fermentational using the wild yeast isolated in Mume(prunus mume s.e.t.z.)and the wild yeasts were identified, concurrently. The alcohols and flavors were analyzed by chromatography. 5 species(Sacch,cerevisiae sp.), 3 species(Pichia genus)and 2 spcecies(Torulopsis sp.)were identified. In the alcohol yielding ability test of yeasts, the yielding ability was 16% in Sacch cerevisiae, and 15.2%, 14.1%, 7.6%and 13.5% in the wild yeasts(#1,2,3,4), respectively, while in the fusel, the percentage of fusel oil was 2.7% in Sacch. cerevisiae, 2.6% in sacch. formosensis, and 0.5%, 0.3%, 0.3%and 0.8% in the wild yeasts(#1,2,3,4,)respectively. The amount of flavors made by yeasts such as Sacch cervisiae, Sacch. formosensis and wild yeast #1 was similar in each case but that of the wild yearst #2,3,4 was much more than above 3 species yeasts.

The construction inspection is conducted by the contractor or construction supervisor after a certain stage of work has been completed. As the consturction inspection task is dependant on construction schedule, however, it is difficult to plan inspection task systematically, resulting in increased supervision costs, delays in construction, and disputes. Therefore, this study aims to integrate inspection work with schedule management to systematize inspection procedures. Firstly, the inspection work is defined based on the construction supervision checklist. Then its relationship with the construction process, required time, and resources for inspection tasks are defined in construction schedule. Lastly, a process management program is used to assess the effects of applying the inspection work and examine changes in the overall construction period and process management. The proposed method in this study can support to plan construction inspection more systematically and to improve the effectiveness of construction quality management.
