Study on Inventory Management Optimization of Small and Medium-sized Retail Companies in the Context of New Retail

The emergence of "New Retail" produces a great impact on the inventory management of retail companies. Using ASY company as the study object, this paper calculates weights of factors affecting inventory management with the Analytic Hierarchy Process (AHP) method to obtain the weight data of each factor before and after the New Retail appears. On this basis, it analyzes how New Retail affects the inventory management of ASY company. Besides, it offers optimization strategies and effect feedback indicators for the following problems faced by this company: pay less attention to delivery method and management system; poor incentive polices for employees; lay less stress on FMCG; too many goods are distributed by manufacturers; heavy workload; increased impact generated by fund restrictions; little knowledge about New Retail; make little efforts to improve employees' learning and innovation ability.

A key design parameter proposal for aerodynamically efficient subsonic blended wing body

Purpose Blended wing body (BWB) is a very advantageous design in terms of low fuel consumption, low emission and low noise levels. Because of these advantages, the BWB is a candidate to become the commercial passenger aircraft of the future by providing a paradigm shift in conventional designs. This paper aims to propose a key design parameter for wing sizing of subsonic BWB and a performance parameter for calculating the lift/drag ratio values of BWBs. Design/methodology/approach The parameter proposed in the study is based on the square/cube law, that is, the idea that the wetted area is proportional to the power of 2/3 of the weight. Data on the weight, wing area, wingspan, lift-to-drag (L/D) ratio for 19 BWB used in the analyzes were compiled from the published literature and a theoretical methodology was developed to estimate the maximum lift to drag ratio of BWBs. The accuracy of the proposed key design parameter was questioned by comparing the estimated L/Dmax values with the actual values. Findings In the current study, it is claimed that the wingspan/(take-off gross weight)(1/3) parameter provides an L/D efficiency coefficient regardless of aircraft size. The proposed key design parameter is useful both for small-scale BWB, that is unmanned aerial vehicles BWB and for large-scale BWB designs. Therefore, the b/Wg(1/3) parameter offers a dimensionless L/D efficiency coefficient for BWB designs of different scales. The wetted aspect ratio explains how low aspect ratio (AR)-BWB designs can compete with high AR-tube-and-wing designs. The key parameter is also useful for getting an idea of good or bad BWB with design and performance data published in the literature. As a result, reducing the blending area and designing a smaller central body are typical features of aerodynamically efficient BWB. Originality/value As the role of the square/cube law in the conceptual aircraft design stage has not been sufficiently studied in the literature, the application of this law to BWBs, a new generation of designs, makes the study original. Estimation of the wetted area ratio using only wingspan and gross weight data is an alternative and practical method for assessing the aerodynamic performance of the BWB. According to the model proposed in the current study, reducing the take-off gross weight of the BWBs using lighter building materials and designing with a larger wingspan (b) are the main recommendations for an aerodynamically efficient BWB.

The Combination of Indigofera Leaf and Corn as Fermented Feed on the Growth of Arabic Chicken (Gallus turcicus)

This study aims to find out the effect of combination of fermented Indegofera leaf and corn on the growth of Arabic chicken. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment consisted of P.1: Commercial Feed; P.2: 80% Indegofera sp leaves + 20% Corn; P.3: 70% Indegofera leaves + 30% Corn; P.4: 60% Indegofera leaves + 40% Corn. Measurement of Arab chickens weight was carried out once a week for one month. The weight data were analyzed using one-way analysis of variance (ANOVA) followed by Duncan's test. The results showed that the combination of fermented feed consisting Indegofera sp leaves and corn had a significant effect (P<0.05) on the growth of Arab chickens. The conclusion shows that fermented feed of Indegofera leaves sp and corn as chicken diet could improve the growth of Arabian chickens.

Live weight performance of three different breed of indonesian local chickens in starter phase

The production of local chickens in Indonesia is determined by the availability of high-quality local chicken stocks. However, information on local chicken performance is limited, therefore, this study aims to determine the live weight performance of three local Indonesian chicken namely Merawang, Murung Panggang, and KUB in the starter phase. The study was conducted at chicken farm located in Semanu Gunung Kidul, Yogyakarta. Meanwhile, the live weight data were collected at the starter phase (0, 2, and 4 weeks. The samples consisted of 196 Merawang, 157 Murung Panggang, and 416 KUB chickens reared in a battery cage in a closed house under similar conditions. Furthermore, the live weight performance data were analyzed using analysis of variance (ANOVA). As a result, the Merawang chicken had the highest live weight (P<0.05) at the day-old chick (DOC) age. At the same age, no significant difference was detected between the KUB and Murung Panggang chicken (P>0.05). However, the live weight of Murung Panggang was significantly higher at 2 and 4 weeks compared to others (P< 0.05). Therefore, it was concluded that there are variations in the live weight of the three local chickens during the starter phase.

The effect of biofilm biofertilizer formula and organic fertilizer dosage to phosphorus uptake and yield of shallot on Vertisols

The research aims to find the effect of biofilm biofertilizer formula and dose of organic fertilizer on phosphorus uptake and yield of shallot on Vertisols. The research was arranged in a completely randomized block design with two factors: dosage of organic fertilizer (0, 10, 20-ton ha-1) and the formula of biofilm biofertilizer (without BiO2, BiO2 1, BiO2 2, BiO2 3). Variables observed are available-P, P-uptake, bulb number, and bulb weight. Data were analyzed using F test followed by DMRT at α = 0.05. The result shows that 20-ton ha-1 organic fertilizer decomposed with biofilm biofertilizer yield highest P-uptake and plant dry weight which increases 322 and 216 % to control treatment (0.50 and 1.26 g plant-1). The use of 10-ton ha-1 of organic fertilizer yield highest bulb number and weight i.e 5.58 bulbs plant-1 and 116 g plant-1 increase 27 and 172% compared to the control. The BiO2 formula only affected to the plant height, and the use of formula 1 able to increase the plant height about 13.5% compared to control treatment.

A statistical quality assessment method for longitudinal observations in electronic health record data with an application to the VA million veteran program

Background To describe an automated method for assessment of the plausibility of continuous variables collected in the electronic health record (EHR) data for real world evidence research use. Methods The most widely used approach in quality assessment (QA) for continuous variables is to detect the implausible numbers using prespecified thresholds. In augmentation to the thresholding method, we developed a score-based method that leverages the longitudinal characteristics of EHR data for detection of the observations inconsistent with the history of a patient. The method was applied to the height and weight data in the EHR from the Million Veteran Program Data from the Veteran’s Healthcare Administration (VHA). A validation study was also conducted. Results The receiver operating characteristic (ROC) metrics of the developed method outperforms the widely used thresholding method. It is also demonstrated that different quality assessment methods have a non-ignorable impact on the body mass index (BMI) classification calculated from height and weight data in the VHA’s database. Conclusions The score-based method enables automated and scaled detection of the problematic data points in health care big data while allowing the investigators to select the high-quality data based on their need. Leveraging the longitudinal characteristics in EHR will significantly improve the QA performance.

Morphometric characteristics of four important fish species from the Rwandan side of Lake Kivu

Inland fisheries are important socio-economic resources for rural communities in Africa. In Rwanda, about two million people directly depend on capture fisheries from Lake Kivu. Sustainable fisheries management requires monitoring of population dynamics that help devise effective intervention strategies. However, the relevant data such as length-length and length-weight relationships do not exist for most of the key species in Lake Kivu. The present study generated morphometric and body weight data for Limnothrissa miodon (n=82), Lamprichthys tanganicanus (n=55), Haplochromis vittatus (n=51) and Haplochromis graueri (n=34) from Lake Kivu. Length-weight relationships (W=aLb) were highly significant for all species (p < 0.0001), high adjusted R2 = 78 to 98% of the variance in weight explained by total length. Negative allometric length-weight relationships were found with regression slope (b) values of 2.7 for Limnothrissa miodon, 2.8 for H. graueri, and 2.8 for L. tanganicanus, and positive (b=3.4) for Haplochromis vittatus. Length-length relationships were highly significant for all species (p ≤ 0.0001), except for the relationship between total and caudal length for L. miodon, and total and caudal peduncle length for L. tanganicanus, both not significant at p > 0.05. The highest R2 was for the relationships between total and standard length for H. vittatus, and total and fork length for L. tanganicanus. No description of length-length relationships exists for these species in literature or in FishBase database. The data generated in the current study will be used to assess changes in fish populations over time.

Pharmacological and Toxicological evaluation of selenium in combination with thiamine in chemically induced hepatocarcinogenesis

Hepatocellular carcinoma (HCC) is currently holding the second rank as a fatal cancer globally. Our hypothesis projects the combined effect of selenium (3mg/kg) and thiamine in combination as an effective treatment for DENA induced carcinogenesis in Wistar rats with an intra-peritoneal single dose of 200mg/kg body weight. Data obtained proved to show a remarkable alteration in body weight and liver profile of DENA exposed rats which were restored by administration of selenium and thiamine combination; our histological reports also revealed reparative changes in the trabaculie mesh work of hepatic cells at higher doses than the normal dietary requirement. Outcomes of the protocol showed remarkable fruitful results for the justification of combined selenium and thiamine as anticancer therapy.
