The determinant factors of coffee cup quality are highly variable and depend on their interaction with coffee production and benefit. This study aimed to analyze soil and climatic factors and their association with the cup quality of Castillo coffee variety of three to five years of age from production units in ecotypes 220A and 221A of the Department of Nariño. The study farms were located in three different altitudinal ranges: ≤1500 m, between 1501 and 1700 m, and >1700 m. Soil, climate, and coffee cup quality variables were analyzed through principal component analysis and cluster analysis. A low level of association was found between climatic and soil nutritional factors and coffee cup quality. Soil Mn, Fe, and Cu contents showed the highest association levels with cup quality, indicated by an average score of 80.89. The highest values of photosynthetically active radiation -PAR- and thermal amplitude were found in La Unión - Nariño, and these variables were associated with the group that obtained the highest cup quality score (82.58). Cup quality was not associated with elevation since the highest scores (85.5 and 82.33) were obtained from production units located at ≤1500 m.a.s.l. and >1700 m.a.s.l, respectively.

The decline in construction productivity across North America since the mid 1970s has been reported by many researchers. The potential exists to achieve major cost savings if the factors underlying this decline can be identified and quantified and solutions are found. The issue is complex, but it is generally acknowledged as an axiom that it is a management problem and within the control of management to rectify. This paper describes the results of a survey of the attitudes of construction professionals across Canada toward factors affecting construction productivity. Special emphasis is made to the differences between Newfoundland and the rest of Canada. Findings for different regions of the country are presented and contrasted. For the purpose of this study, the factors have been classified into six groups: (i) contract environment, (ii) planning, (iii) site management, (iv) working conditions, (v) working hours, and (vi) motivation. Major factors affecting productivity are identified. The survey questionnaire addressed these factors within the groups indicated. Respondents commented freely on factors that they considered to be of great importance to construction productivity, such as quality of labor skill, project communication, timeliness, and equipping of crews. Key words: construction productivity, Canadian construction, unemployment insurance benefit.

This study investigated the spatial variation in the water quality parameters of Burullus Lake using multivariate analysis and MIKE21 model. The lake was classified into zone-1 at north-east (Z1), zone-2 at south-east (Z2), zone-3 at north-middle (Z3), zone-4 at south-middle (Z4), zone-5 at north-west (Z5), zone-6 at south-west (Z6), and zone-7 at west (Z7). The obtained parameters were temperature 21.5±5.0 ºC, pH 8.2±0.6, dissolved oxygen (DO) 5.9±1.0 mg/L, biological oxygen demand (BOD) 23.9±5.7 mg/L, NH3-N 2.5±0.3 mg/L, NO2-N 1.9±0.3 mg/L, NO3-N 1.2±0.3 mg/L, PO4-P 1.9±0.3 mg/L, SiO4 3.2±0.1 mg/L, Chlorophyll-a (Chl-a) 88.2±10.8 µg/L, and salinity 3.2±1.0 g/L. Principal component analysis showed that agricultural drainage water was the key factor influencing the water quality characteristics of Burullus Lake. Water quality index (WQI) varied between “Bad” to “Medium”, suggesting that the lake wasn’t suitable for irrigation and fish growth; however, it was appropriate for some aquatic life. A MIKE21 model was developed to provide a recommendation scenario that could be used to enhance the water quality of Burullus Lake. By improving the water quality of precise drains (namely drains 7 and 8), the WQI at Z4 and Z6 modified from “Bad” to “Medium”. The period required to achieve this self-purification was 5 months.

The purpose of this study is to identify the financial factors that enhance the financial competitiveness of small and medium enterprises (SMEs) in Gujarat, India. The principal component analysis has been applied to extract the financial factors from financial performance ratios of a sample size of 38 stock exchange SMEs, based in Gujarat, India. The ranking has been given to the SMEs based upon their factor score and comprehensive score. The results show that profitability, management efficiency, liquidity and leverage factors are the major factors affecting the financial competitiveness of SMEs. The study covers only one state of the country, and the findings from different states may differ and need to get verified. Despite the highest contribution of SMEs in the GDP of India, there exist very few Indian studies on SME competitiveness. This study contributes to filling this gap.

SUMMARYInformation on the total dry-matter intake (TDMI), concentrates supplied (C), live weight (LW), week of lactation (WL), milk yield (MY) and composition, quality of forage fed to, and parities of, 385 cows from five different sources were assembled to develop appetite prediction equations. The equations were based on multiple regression and least squares constants and were calculated using the data from each source and the data pooled from all sources. The major factors affecting total dry-matter intake (TDMI) were C, LW, WL and MY and for the pooled data these factors explained 73–76% (R2) of the total variation in TDMI. The predictive values of some of the equations were tested against independent sets of data and for groups of cows and individual cows, the equations predicted TDMI within ±1·1 and 1·6 kg, respectively. The application of the equations in the field is discussed and some suggestions made for increasing the R2 of future appetite equations.

Since ancient times, scientists and philosophers were interested in the sense of taste, the mechanisms of its development, anatomical structures responsible for taste, and its importance. Currently, it is clear that food preferences are the main determinant of the development of nutrition and food behavior. Food preferences begin to develop in the early childhood and retain throughout the life. Therefore, inculcating correct nutritional behavior with respect to healthy food is a promising approach to improve the quality of diet being one of the key factors affecting human health. This article addresses current data on morphology, genetics, embryology, and ontogeny of gustatory system as well as major factors affecting the development of food preferences in a child. Most of these factors are modified ones, therefore, the aim of this review is to draw the attention of pediatricians since this is pediatrician who makes evidence-based recommendations on child nutrition and provides adequate feeding strategy.Keywords: genetics, food preferences, taste, taste receptors, children, smell, ontogeny, tongue, baby food, healthy lifestyle.For citation: Zakharova I.N., Dmitrieva Yu.A., Machneva E.B., Tsutsaeva A.N.

<b><i>Background:</i></b> The prolonged immobilization suggested after breast cancer (BC) surgery causes morbidity. Patients search the Internet, especially social networks, for recommended exercises. <b><i>Objective:</i></b> The aim of this observational study was to assess the quality of YouTube videos, accessible for any patient, about exercises after BC surgery. <b><i>Methods:</i></b> A systematic search was performed on YouTube. One hundred and fifty videos were selected and analyzed. Two statistical analyses were conducted based on machine-learning techniques. Videos were classified as “Relevant” and “Non-Relevant” using principal component analysis models. Popularity was evaluated by Video Power Index (VPI), informational quality and accuracy were measured using the DISCERN Scale and Global Quality Scale (GQS). Scoring criteria for exercises were established according to the exercises recommended by the Oncology Section of the American Physical Therapy Association (APTA). Interobserver agreement and individual correlations were statistically examined. <b><i>Results:</i></b> DISCERN scored a mean of 50.97 (standard deviation [SD] 19.19). HONcode scored 78.30 (11.02) and GQS scored 3.49 (0.74). Average number of views was 53,963 (SD 67,376), mean duration was 9:42 min (9:15), mean days online was 2,158 (922), mean view ratio was 27.14 (30.24), mean likes was 245 (320.5), mean dislikes was 13.4 (14.2), and mean VPI was 93.48 (5.42). <b><i>Conclusion:</i></b> The quality of YouTube videos of recommended exercises post-BC surgery is high and can be a translational activity to improve patients’ behavior. Health institutions and NGOs, with higher popularity levels than academic institutions, should consider this information when implementing new policies focused on video quality which can contribute to adaptive behavior in patients.
