The results of the study of solid-volume/stacked-volume ratio, the relationship between heights and diameters, as well as the dimensional and qualitative structure of oak stems in mature and overmature forest stands are presented. Correlation analysis is performed and interrelations between taxation indicators are evaluated. Mathematical models of height, form factor and dimensional-qualitative structure of tree stems were developed, on the basis of which volume tables, a class scale of heights and tables of the dimensional and qualitative structure of tree oak stands were constructed. It was established that the percentage of output of coarse, medium and small merchantable wood, firewood and waste wood doesn’t significantly depend on the class of heights. Comparison of the developed standards with the current ones showed that the yield of commercial timber according to the results of the conducted study is 5% on average, and that of coarse commercial wood for stems with a diameter of more than 48 cm is 3-8% less than the current standards.

Age And Sex

SummaryAs part of a population study on chronic lung disease in the Netherlands, an investigation is made of the relationship of both age and sex with indices describing the maximum expiratory flow-volume (MEFV) curve. To determine the relationship, non-linear canonical correlation was used as realized in the computer program CANALS, a combination of ordinary canonical correlation analysis (CCA) and non-linear transformations of the variables. This method enhances the generality of the relationship to be found and has the advantage of showing the relative importance of categories or ranges within a variable with respect to that relationship. The above is exemplified by describing the relationship of age and sex with variables concerning respiratory symptoms and smoking habits. The analysis of age and sex with MEFV curve indices shows that non-linear canonical correlation analysis is an efficient tool in analysing size and shape of the MEFV curve and can be used to derive parameters concerning the whole curve.

This study examines the influence of receivables on liquidity at PT. Graha Tumarima. Sukabumi City for 5 years, with a sampling technique using a purposive sample in the form of financial statement data from 2010 to 2014 using a table of trade receivables and company liquidity. In this study, researchers refer to the theory of Bambang Riyanto (2008: 94) as the connecting theory of the title. This study aims to determine whether there is a relationship and influence between receivables and liquidity at PT. Graha Tumarima. The research design uses the method of exposing the facto, the method of data collection aims to test the hypothesis by using correlation analysis, determination, regression and hypothesis testing with t-test. The results of this study show the influence of receivables on liquidity is shown by the value of r = 0.888, meaning that receivables have a very strong relationship to liquidity. The nature of the relationship is positive, meaning that if the value of cooperative credit is higher the liquidity will be higher. Conversely, if the value of receivables decreases, liquidity will decrease. The magnitude of the influence of receivables on liquidity is shown by the value of R Square / Determination Coefficient of 0.789 or 78.9% thus the receivables have an effect of 78.9% on cooperative liquidity. Hypothesis testing uses the t test, that t arithmetic = 3.347 while t table = 3.182 means t arithmetic> t table. Means that Ho is rejected and Ha is accepted. There is an influence between the receivables on liquidity at PT. Graha Tumarima, Sukabumi City

This paper discusses the influence of the production parameters on the moisture related comfort characteristics of the compression garments that differ according to the tension applied during the production and elastane count. Correlation analysis, two sided independent t-test analysis and ANOVA tests were applied to analyze the relationship between the production parameters and comfort characteristics which are absorption, vertical and transfer wicking and drying. It was found that tension and elastane composition affect the comfort characteristics by changing the porosity, thickness and the pathways within the fabric.

Abstract Airborne laser scanning (ALS) is one of the most innovative remote sensing tools with a recognized important utility for characterizing forest stands. Currently, the most common ALS-based method applied in the estimation of forest stand characteristics is the area-based approach (ABA). The aim of this study was to analyse how three ABA methods affect growing stock volume (GSV) estimates at the sample plot and forest stand levels. We examined (1) an ABA with point cloud metrics, (2) an ABA with canopy height model (CHM) metrics and (3) an ABA with aggregated individual tree CHM-based metrics. What is more, three different modelling techniques: multiple linear regression, boosted regression trees and random forest, were applied to all ABA methods, which yielded a total of nine combinations to report. An important element of this work is also the empirical verification of the methods for estimating the GSV error for individual forest stand. All nine combinations of the ABA methods and different modelling techniques yielded very similar predictions of GSV for both sample plots and forest stands. The root mean squared error (RMSE) of estimated GSV ranged from 75 to 85 m3 ha−1 (RMSE% = 20.5–23.4 per cent) and from 57 to 64 m3 ha−1 (RMSE% = 16.4–18.3 per cent) for plots and stands, respectively. As a result of the research, it can be concluded that GSV modelling with the use of different ALS processing approaches and statistical methods leads to very similar results. Therefore, the choice of a GSV prediction method may be more determined by the availability of data and competences than by the requirement to use a particular method.

Capsaicinoid content, among other factors, affects the perception of spiciness of commercial kimchi. Here, we investigated whether the physicochemical properties of kimchi affect the spicy taste of capsaicinoids perceived by the tasting. High-performance liquid chromatography (HPLC) was used to evaluate the capsaicinoid content (mg/kg) of thirteen types of commercial kimchi. The physicochemical properties such as pH, titratable acidity, salinity, free sugar content, and free amino acid content were evaluated, and the spicy strength grade was determined by selected panel to analyze the correlation between these properties. Panels were trained for 48 h prior to actual evaluation by panel leaders trained for over 1000 h according to the SpectrumTM method. Partial correlation analysis was performed to examine other candidate parameters that interfere with the sensory evaluation of spiciness and capsaicinoid content. To express the specific variance after eliminating the effects of other variables, partial correlations were used to estimate the relationships between two variables. We observed a strong correlation between spiciness intensity ratings and capsaicinoid content, with a Pearson’s correlation coefficient of 0.78 at p ≤ 0.001. However, other specific variables may have influenced the relationship between spiciness intensity and total capsaicinoid content. Partial correlation analysis indicated that the free sugar content most strongly affected the relationship between spiciness intensity and capsaicinoid content, showing the largest first-order partial correlation coefficient (rxy/z: 0.091, p ≤ 0.01).

This article examines the relationship between learning and behavioural evaluation among religious officers in Malaysia after attending the Manual on HIV/AIDS in Islam Training Programmes organized by the Islamic Development Department of Malaysia (JAKIM). The training programmes were implemented to deliver the most accurate and the latest information on HIV / AIDS as well as to train religious officers in Malaysia to address the issues among Muslims. The training programmes apply the theoretical and practical activities where participants had the opportunity to carry out outreach activities with People Living with HIV / AIDS (ODHA). Quantitative methods through questionnaires were used to obtain data. A total of 350 religious officers who had attended the training programmes were selected as respondents by simple random sampling technique. Pearson correlation analysis was conducted to determine the relationship between the learning and behavioural evaluation. The results of the Pearson correlation analysis found that there was a significant relationship between learning evaluation in terms of the information obtained from programmes’ contents and behaviour evaluation with r = 0.489 and sig = 0.000 (p <0.05) at the medium positive range.. While the relationship between learning evaluation in terms of the information obtained from outreach activities with behavioural evaluation showed a strong positive correlation with the strength values obtained were r = 0.539 and sig = 0.000 (p <0.05). This analysis shows that the information acquired through the training program Manual Islam and HIV / AIDS has been successful in changing the behaviour of religious officers’ awareness in terms of the role of dakwah to ODHA.

The Relationship

Species of buried, germinating seeds and species occurring in the vegetation are compared for two Colorado subalpine forest stands, one dry and one mesic, both over 325 years old. The total numbers of seeds found were small and the correspondence with species in the vegetation was poor. This is consistent with reports from other old-growth forests and may be accounted for by a combination of low seed input and rapid loss of viable seeds from the soil reservoir for old-growth forest species.

The tussive and bronchoconstrictive effects of histamine inhalation in 7 normals, 7 asthmatics, and 24 patients with chronic cough (PCC) were measured by counting coughs during a standard histamine inhalation challenge. All PCC had a tussive response. Fifteen PCC exhibited significant linear correlations between cough count and either the change in forced expiratory volume at 1.0 (delta FEV1) or conductance-volume ratio (sGaw) (delta sGaw). Normals and asthmatics had little or no cough. Metaproterenol pretreatment in seven PCC reduced both the FEV1 and cough response to histamine without changing the relationship between cough and delta FEV1. The tussive and bronchoconstrictive effects of methacholine inhalation were also measured in 7 asthmatics and 16 PCC. One asthmatic coughed. Fifteen PCC coughed. There were significant linear correlations between cough count and delta FEV1 or delta sGaw in 10 PCC. At comparable delta FEV1 and delta sGaw, histamine produced more cough than methacholine. These data indicate that during inhalation of histamine or methacholine by PCC cough is related to, and may be caused by, bronchoconstriction. Histamine also causes cough by an additional mechanism not related to bronchoconstriction.

Sei Siulak Deras Irrigation Area is one of the Irrigation Areas located in Kerinci Regency based on the decision of Dinas Pekerjaan Umum dan Perumahan Rakyat (PUPR) regulations No.12/PRT/M/2015 concerning criteria and estabishment of Irrigation Area status with an area of 5,801 Ha. The authority for operational and maintenance implementation is handled by the Dinas PUPR of Jambi Province ( RTRW of Jambi Province, 2013). The performance of the Sei Siulak Deras irrigation network infrastructure is inseparable from the available maintenance budget, for this reason, it is necessary to conduct a study that analyzes the relationship between routine maintenance costs for the performance of irrigation network infrastructure in the Sei Siulak Deras irrrigation area of Kerinci District, Jambi Province.  In this study an examination of the existing conditions of irrigation networks involving 1 observer and 6 irrigation workers, the irrigation network inspection using the standards issued by the Operation and Maintenance Agency of the Dinas PUPR of Jambi Province. From the results of the correlation analysis the cost of routine maintenance on the performance of irrigation network infrastructure is 0.9, this indicates a strong relationship between the two variables. While the maintenance budget allocated by the government to the maintenance of irrigation network infrastructure is very lacking, amounting to IDR 806,081,000 from the budget for the maintenance of irrigation network infrastructure of IDR 3,580,984,372.57.
