Research on influence of environment factors to yield and quality traits of Perilla frutescen / 中国中药杂志

The research is aimed to study of the influence of environmental factors on the yield and quality traits, and find out the regularity of the growth and development of perilla. The main environmental factor data in six ecological area in Guizhou province were collected, and the correlation analysis with yield and quality traits of 15 perilla strains was conducted. The results showed that the cultivation environment has significant effects on the yield and quality traits of perilla. The effect of environment on main yield composed traits, contained grain number in top spike, effective panicle number per plant, plant height, top spike length, growth period, and thousand seed weight was degressive. In the different environmental factors, the latitude showed positive correlation with yield, growth period and effective panicle number per plant, and negative correlation with top spike length and grain number in top spike. Elevation showed negative correlation with the growth period of perilla. The perilla yield increased at first and then decreased with altitude rising, with the maximum in the 800 m altitude. The 600-900 m altitude is suitable area for perilla. Except for positive correlation with the plant height, and negative correlation with top spike length, the longitude showed in apparent impact on other traits. Sunshine duration, temperature and rainfall accumulation showed different effect on the different perilla strains. For yield composed traits, the sunshine duration was negatively correlation with the plant length. The accumulated temperature and mean temperature showed negative correlation with the main spike length, the rainfall showed negative correlation with the precipitation and growth period, plant height, ear number. The environmental impact on the oil compounds decreased with oleic acid, stearic acid, linoleic acid, -linolenic acid, palmitic acid and oil content. Correlation analysis showed that the significantly negative correlation between the oil content and palmitic acid and linoleic acid content, and the positive correlation between linolenic acid content, -linolenic acid content showed significant negative correlation with other fatty acids composition, and palmitic acid, stearic acid, oleic acid, linoleic acid showed significant positive correlation with each other. The influence of different environmental factors on the quality of perilla were as follows: the oil content was positively associated with elevation and sunshine duration. -Linolenic acid content showed negative correlation with longitude, latitude, accumulated temperature and mean temperature, but positive correlation with altitude, sunlight and rainfall capacity. The correlation between palmitic acid, stearic acid, oleic acid, linoleic acid and environmental factors showed contrast character of -linolenic acid. This study detailed discussed the influence of environmental factors on the quality of perilla, which provided the foundation of ecological planting technology and geoherbalism research of perilla.

Person - job fit and the work commitment of IT Personnel

Tem sido dada uma importância muito maior à participação dos trabalhadores e retenção desde que a Índia está enfrentando a maior taxa de atrito globalmente Economic Times, 2015¹. Assim, considerando os fatores de Pessoa - job apto a interpretar o impacto no compromisso de trabalho é muito bem essencial, especialmente no Compromisso scenario.Work atual é um elemento vital de qualquer constituição que tem um impacto notável na produtividade e funcionamento . Mas, quando os funcionários vão sentir o compromisso de trabalho é o futuro pergunta. Existe uma forte relação entre ajuste pessoa - trabalho e compromisso de trabalho . ajuste pessoa - trabalho é a compatibilidade entre competência e habilidades da pessoa e as exigências do trabalho Zheng et al.². Se existe uma incompatibilidade entre o ajuste pessoa - trabalho, então as consequências podem resultar em compromisso de trabalho pobre, baixa satisfação no trabalho e extremamente menor envolvimento no trabalho. OBJETIVO: Este estudo analisou os principais fatores que contribuem para a pessoa- a compatibilidade de trabalho entre TI trabalhadores e também analisou a relação e o impacto da compatibilidade de trabalho Person- no compromisso de trabalho. MÉTODO: Exploratory Factor de Analysis (EFA) foi usado para filtrar os fatores-chave inicialmente, seguido por uma técnica de regressão linear para determinar o impacto da pessoa- fatores de compatibilidade emprego no compromisso de trabalho em uma amostra de 300 empregados. EFA utilizada análise de componentes principais para a extração e Promax para rotação . Finalmente a análise de regressão foi realizada para prever o compromisso de trabalho por meio de variáveis estatisticamente significativas de compatibilidade pessoa - trabalho. RESULTADOS: Os resultados revelaram os principais fatores que determinam o nível de compromisso de trabalho são condições de RH, remuneração e benefícios e relacionamento entre os colegas de trabalho. CONCLUSÃO: Os principais fatores que são responsáveis pela criação de compromisso de trabalho entre empregados são Relacionamento, Políticas e estratégias de RH, remuneração e benefícios, o trabalho autonomia e crescimento do empregado. Os regride mais contribuem que representa a criação de compromisso de trabalho são as políticas de RH, remuneração e benefícios, o crescimento do empregado e trabalhar autonomia. O impacto da compatibilidade pessoa-trabalho no compromisso de trabalho foi estudada através de análise de regressão e isso implica que para cada aumento de uma unidade na política de RH, a 0,52 (coeficientes unstandardised) aumento no compromisso de trabalho está previsto e foi acabou como uma variável de maior impacto para prever compromisso de trabalho. Os coeficientes para Relacionamento (B = 0,330, sig = 0,000), Políticas de Recursos Humanos (B = 0,519, sig = 0,000), remuneração e benefícios (B = 0,386, sig = 0,000) e Crescimento Empregado (B = 0,290, sig = 0,001) foram significativamente diferente de 0, desde o seu valor de p era 0,000 que é menor do que 0,05. Os coeficientes para o Trabalho Autonomia (B = 0,154, SOG = 0,081) não foi estatisticamente diferente de zero, porque o seu valor-p é 0,081, que é maior do que 0,05. A implicação desta pesquisa vai ajudar os gestores a criar um ambiente de trabalho bem compatível concentrando-se em importantes construções de compatibilidade trabalho pessoa- que têm um possível efeito positivo no compromisso de trabalho e reduzindo, assim, a intenção de rotatividade dos empregados. Ainda mais aumentou compromisso de trabalho resultará em resultados do trabalho positivos, tais como a satisfação no trabalho e comprometimento organizacional

There have been given a much higher importance to employee commitment and retention since India is experiencing the highest attrition rate globally Economic Times, 2015¹. Hence, considering the factors of Person-job fit to interpret the impact towards work commitment is very well essential, especially in the current scenario. Work Commitment is a vital element in any organization which has outstanding impact on productivity and functioning and hence it is very much vital to have a committed workforce which is necessary in this competitive environment and tight labour market. In the same way, there is considerable amount of evidence that if P-J fit is high then it will have a direct impact on organization commitment also. Person-job fit is the compatibility between person's competency and abilities and the requirements of the job Zheng et al.². If there exists a mismatch between person-job fit then the consequences might result in poor work commitment, low job satisfaction and extremely lower involvement in the job. OBJECTIVE: This study analyzed the key factors that contribute to Person- job compatibility among IT workers and also analyzed the relationship and impact of Person- job compatibility towards work commitment. METHODS: Exploratory Factor Analysis (EFA) was used to filter the key factors initially, followed by a linear regression technique to determine the impact of Person- job compatibility factors in work commitment on a sample of 300 employees. EFA used Principal Component analysis for extraction and Promax for rotation. Finally regression analysis was carried out to predict the work commitment through statistically significant person-job compatibility variables. RESULTS: The impact of person-job compatibility on work commitment was studied through regression analysis and it imply that for every unit increase in HR Policy, a 0.52(unstandardised coefficients) increase in work commitment is predicted and it has been turned out as a most impacting variable to predict work commitment. The coefficients for Relationship (B =.330, sig =.000), HR Policies (B =.519, sig =.000), Pay and Benefits (B =.386, sig =.000) and Employee Growth (B =.290, sig =.001) were statistically significant, since its p-value is .000 which is smaller than .05. The coefficients for Work Autonomy (B =.154, sig = .081) was not statistically significant, since its p-value is 0.081 which is greater than.05. CONCLUSION: The major factors responsible for creating work commitment among IT employees are Relationship, HR Policies and strategies, Pay and benefits, Work autonomy and Employee growth. The most contributing regressors which accounts for creating work commitment are HR policies, Pay and benefits, Employee growth and work autonomy

Diferenças na intensidade e na expansão da pústula da ferrugem do cafeeiro em dois acessos de Hemileia vastatrix / Differences in the intensity and pustule expansion of coffee rust for two Hemileia vastatrix accesses

Objetivou-se, neste trabalho, estudar, em ambiente controlado, as diferenças na intensidade de doenças e na expansão da pústula de dois acessos de Hemileia vastatrix, coletados em plantas da cultivar Catuai das cidades de Coromandel (COR2), no Alto Paranaíba e de Ijaci (IIJ1), no Sul de Minas Gerais. As plantas inoculadas foram submetidas a três temperaturas (15, 20 e 25ºC) e três períodos de molhamento foliar (24, 48 e 72 horas de molhamento foliar), em esquema fatorial com três repetições. Ambos os acessos apresentaram maior severidade da doença quando submetidos a 24 horas de molhamento foliar, após a inoculação. A maior freqüência de infecção do IIJ1 foi a 15ºC, no entanto, a temperatura não influenciou essa variável para COR2. Houve maior severidade da ferrugem em COR2 a 25ºC. A maior expansão da pústula, em folhas inoculadas com IIJ1, foi a 15ºC com 7,59cm², e a menor a 25 ºC, com 5,37cm², enquanto para COR2 houve aumento à medida que se elevou a temperatura de 15 para 25ºC, de 1,44 para 6,62 cm², respectivamente. Accessos provenientes de Ijaci e de Coromandel apresentaram diferenças na intensidade da ferrugem e na expansão das pústulas em ambiente controlado.

The aim of this work was to study, under controlled environment, the differences in the disease intensity and pustule expansion of two Hemileia vastatrix accesses, sampled in cultivar Catuai coffee (Coffea arabica L.) plants from Coromandel (COR2) and Ijaci (IIJ1), towns located respectively in the West and South of Minas Gerais State. The inoculated plants were submitted to three temperatures (15, 20 and 25ºC) and three leaf wetness durations (24, 48 e and 72 hours) in a factorial scheme with three replicates. Both accesses presented a higher disease severity when submitted to 24h leaf wetness duration after inoculation. The higher infection frequency for IIJ1 was at 15ºC, while the temperature did not influence this variable for COR2. There was a higher severity for COR2 inoculated plants when incubated at 25ºC. The higher pustule expansion, for leaves inoculated with IIJ1 was at 15ºC with 7.59cm² and a lower at 25ºC, with 5.37cm², while for COR2 when temperature raised from 15 to 25ºC, there was an increase in the pustule expansion from 1.44 to 6.62 cm², respectively. Fungal lines from Ijaci and from Coromandel presented differences in the intensity and pustule expansion of rust, under controlled environment.

The Effect of Environmental Factors to the Mobility Disability in Independent Subjects with Stroke

OBJECTIVE: To investigate the effect of environmental factors on the ability of mobility in subjects with chronic stroke who can perform nearly independent activities of daily living (ADL). METHOD: Sixty one patients were divided into three groups (superior, middle, and inferior) by the degree of independent walking. Modified self-administered questionnaire was completed to report how well the patients encountered the environmental elements faced in community mobility. In addition, all patients were assessed to find out the difference of ADL performance, Berg balance scale (BBS), 10 m walking time (10 mWT) and patterns of 'going out' among the three groups. RESULTS: The group 1 (superior group) had shown better performance than group 2 (middle group) and group 3 (inferior group) in performance of ADL, BBS, 10 mWT. Secondly, the group 1 visited more places or destinations per day than the group 2 and 3, and they used more various transportation systems than other groups. Finally, there were significant differences in the distance dimension, the temporal dimension, terrain dimension (except for a 'getting on a elevator' component), and density dimension among the groups. CONCLUSION: Environmental factors as well as functional abilities could affect the mobility of subjects with chronic stroke. This result suggests that any kinds of compensation and the supports of social institutions are needed even in subjects of nearly independent ADL for their improvement of mobility and convenience.
