Roof gardens/Rooftop farm are most often found in urban environments. Plants have the ability to reduce the overall heat absorption of the building which then reduces energy consumption. Plant surfaces however, as a result of transpiration do not rise more than $4-5^{\circ}C$ above the ambient and are sometimes cooler. As Urban agriculture in an accessible rooftop farm, space becomes available for localized small-scale urban agriculture, a source of local food production. An urban garden can supplement the diets of the community it feeds with fresh produce and provide a tangible tie to food production.

著者(1971)는 앞서 忠淸北道 槐山郡 延豊面 錦垈里의 心伏窟에서 採集한 수컷을 holotype으로 하여 도토리거미 科(Symphytognathidae)에 屬하는 新種 Conoculus simboggulensis 도토리거미를 記載한 바 있다. 그 當時 採集되지 않았던 암컷이 近者에 發見되었기에 이에 암컷에 對하여 記載하였다. 이 암컷의 發見으로써 本種이 洞窟 밖에서도 棲息한다는 事實이 밝혀졌다. 여러모로 미루어 本種은 好洞窟性(troglophilous)의 거미로 생각된다.

The hydroxydation of the saturated fatty acids in order to prepare hydroxy fatty acids in the presence of catalysts was reported by several workers. The considering commercial applications of this reaction, authors studied on the hydroxydation of natural fats composed of nonhydroxy saturated fatty acids. Tallow and stearic acid were tested with manganese dioxide as catalyst, $110 {\pm}3^{\circ}C,$ and under atmospheric oxygen. The highest hydroxyl values were obtained at 20 hours for tallow, 107.6 and at 14 hours for stearic add, 116.0.

이차원 평면에 직교다각형이 주어져 있을 때, 직교다각형 위에 45도 각도로 기울어진 면들로 구성된 지형 구조인 지붕(roof)을 정의할 수 있다. 본 논문에서는 직교다각형에 대한 지붕의 다양한 기하학적 성질을 살펴본다. 이것은 인공위성으로부터 얻은 건물의 평면도 이미지로부터 3차원 지붕구조를 획득하여 출력함으로써 사실감있는 영상을 제공하는 데 활용될 수 있다.

This paper introduces several decision-making problems that need to be solved in order to facilitate the efficient operation of container terminals. These decision-making problems include the berth planning problem, the quay crane scheduling problem, the unload/load sequencing problem, the yard allocation problem, and the short-term scheduling of transporters and yard cranes. These problems can be classified into strategic decision problems, tactical decision problems, and real time operational decision problems. This paper proposes definitions of the problems that can be used to develop mathematical models for the problems.

Objectives: The purpose of this study was to evaluate food hygiene and safety knowledge, attitudes, and practices (KAP) among the elementary school children, and furthermore, to explain the interrelations among these three variables. A second purpose was to compare gender differences of KAP. Methods: A self-administered, structured questionnaire was designed and completed by 376 elementary school children. A five-point Likert scale with twenty questions was used to gather information. Data was analyzed by frequency analysis, Pearson's correlation and analysis of variance or Student's t-test. Results: Children generally had good knowledge of food hygiene and safety, and knowledge of children was superior to the attitudes and also to their practices (p < 0.05). The attitude score was mediated between knowledge and practice scores. Significant differences (p < 0.05) were found between boys and girls in an item of knowledge, three items of attitudes, and six items of practices. A significant positive correlations were observed between knowledge and practices (${\gamma}$ = 0.70, p < 0.001), and between attitudes and practices (${\gamma}$ = 0.45, p < 0.001), as well as between attitudes and practices (${\gamma}$ = 0.51, p < 0.001), revealing that increased knowledge and even attitudes toward food hygiene safety could result in positive change in practices or behaviors. Conclusions: The results of this study indicate that despite good knowledge and attitudes of children, their practices toward food hygiene and safety are not acceptable. Gender differences in practices were highlighted. In order to create effective educational interventions on the food hygiene and safety of children, a better understanding of their awareness and the required related information is necessary.

Objective: This study aimed to identify the relationship between bovine brucellosis prevalence, farmers' knowledge, attitude, practice (KAP), and social factors on migratory draft cattle and smallholder dairy farms in the central dry zone of Myanmar. Methods: This cross-sectional study was conducted on 54 migratory and 38 dairy cattle farms between August 2020 and February 2021. A structured questionnaire was used to identify farmers' behaviors. Bulk milk was sampled and tested using indirect enzyme-linked immunosorbent assay (I-ELISA). STATA 17 was used for all the analyses. Results: Migratory cattle farms had a higher farm level brucellosis prevalence (14.8%) than dairy farms (2.6%; χ² = 3.75; df = 1; p = 0.05). Only 2.8% of the farmers had knowledge about brucellosis, while 39.1% and 41.6% had attitudes and farm practices with respect to brucellosis, respectively in the study area. Socio-economic attribute of training in animal husbandry (p<0.01), raising system (p<0.01), practice of separating the aborted cow (p<0.01) were negatively associated to brucellosis. The overall farm level brucellosis prevalence was strongly associated with cattle herd size (p = 0.01), free movement grazing practices (p<0.01), practice of self-removal of placental debris without using personal protective equipment (p<0.01) and farmers' attitudes towards eating cow placenta debris (p<0.01). Conclusion: Farmers had little knowledge of brucellosis. Attitudes and practices differed significantly between migratory and dairy farmers. Training and extension programs are necessary to make farmers aware of their KAP situation since livestock migration and the custom of eating cow placental debris contribute to the spread of brucellosis. Persistent efforts are required to reduce the adverse effects of brucellosis. Therefore, the study suggests that a feasible control intervention and public awareness campaigns need to be conducted regarding methods of preventing human exposure to brucellosis.
