Authors: PRAKASH SWETA , DUBEY KAMINI , KONTU MEENUPRIYA
Published: June 2022

Objective: The aim of the present study is to examine preliminary phytochemical investigations, qualitative analysis, and antifungal activity of Barleria prionitis L. leaf extracts.
Methods: Aqueous and crude extract of B. prionitis leaf powder examined by Poisoned food assay to find out the inhibition (%) of fungi at 1 (%), 2 (%), and 3 (%) concentrations.
Results: Flavones, flavanols, flavonols, saponins, and other phytochemicals were observed in leaf powder extract. B. prionitis crude extract inhibits A. flavus by 48.74 (%).
Conclusion: This study shows useful preliminary, phytochemical investigation of B. prionitis L. leaf extracts as well as its antifungal activity. Further research needs to be carried out to purify other compounds contained and to conduct bioactivity assays. The leaves crude extract has depicted antifungal activity against Aspergillus flavus and Aspergillus niger. The aqueous extract of leaves seemed to not affect the fungal strains that were examined. The findings suggest that crude extracts of Barleria prionitis L. leaves provide the substantial potential for the development of a completely new broad range of antifungal herbal formulations.

Authors: GUPTA MEGHNA  , NAVJOT KAUR , K GUPTA VITULL , PRANAV SINGLA , MEENAKSHI SINGLA
Published: June 2022

Objectives: COVID-19 pandemic has triggered an unprecedented global scientific collaboration to develop COVID-19 vaccines which is the most effective way to defeat COVID-19 pandemic. The WHO has identified vaccine hesitancy as a grave global health threat and even after 7 months of free vaccination program, India is lagging behind to achieve the targets essential for herd immunity. Hence, we initiated this survey to study the perceived barriers and motivators for delayed acceptance of first dose of COVID-19 vaccination.
Methods: A survey was conducted during free COVID-19 vaccination camps using a pretested, validated, and anonymous pro forma including eight questions regarding perceived barriers and six regarding perceived motivators for acceptance of the first dose of COVID-19 vaccination and valid responses were analyzed according to age groups and gender.
Results: During our survey, 1144 valid responses were received and analyzed. Results showed fear of side effects as the most sighted barrier among study population, gender, and age groups. Compulsory requirement of vaccination for joining job/college was the most sighted motivator among study population, gender, and 18–30 years age group whereas fear of 3rd wave was most sighted motivator among 31–44 years, 45–59 years, and >60 years age group.
Conclusion: In spite of free COVID-19 vaccine and intensive campaigns, it seems that adequate vaccination targets might not be achieved and results of our survey suggest needs for increased focus on the perceived barriers as well as the perceived motivators to increase vaccination acceptance.

When we looked at people who had hypertension, diabetes mellitus, and high cholesterol, we found that the NLR value was significantly higher in people with these diseases (p=0.05).
Conclusion: We found that NLR is an excellent way to predict COVID-19-infected patients who are likely to get a lot of other illnesses and have a lot of problems early on.
The Quality of Drinkable Water using Machine Learning Techniques
Authors: Pal Osim Kumar
Published: June 2022

Predicting potable water quality is more effective for water management and water pollution prevention. Polluted water causes serious waterborne illnesses and poses a threat to human health. Predicting the quality of drinkable water may reduce the incidence of water-related diseases. The latest machine learning approach has shown promising predictive accuracy for water quality. This research uses five different learning algorithms to determine drinking water quality. First, data is gathered from public sources and presented in accordance with World Health Organization (WHO) water quality standards. Several parameters, including hardness, conductivity, pH, organic carbon, solids, and others, are essential for predicting water quality. Second, Random Forest (RF), Support Vector Machine (SVM), Artificial Neural Network (ANN), Deep Neural Network (DNN), and Gaussian Nave Bayes are used to estimate the quality of the drinking water. The conventional laboratory technique for assessing water quality is time-consuming and sometimes costly. The algorithms proposed in this work can predict drinking water quality within a short period of time. ANN has 99 percent height accuracy with a training error of 0.75 percent during the training period. RF has an F1 score of 87.86% and a prediction accuracy of 82.45%. An Artificial Neural Network (ANN) predicted height with an F1 score of 96.51 percent in this study. Using an extended data set could improve how well predictions are made and help stop waterborne diseases in the long run.
De plumas sin escrúpulos: Adolfo Carrillo y otros periodistas mercenarios durante el Porfiriato
Authors: Gómez Cañedo César
Published: June 2022

El presente artículo tiene como objetivo dar a conocer la producción de algunos libelos que adquieren formas literarias en el periodo del Porfiriato, así como autores de los mismos que han sido poco valorados desde la literatura. Principalmente se rescata la figura y la obra de Adolfo Carrillo (1855-1926) y sus falsas memorias, o memorias-libelo, que puso a circular para atacar a actores políticos del periodo e, indirectamente, al régimen de Díaz: Memorias del Marqués de San Basilisco (1897) y especialmente las entonces populares Memorias de Sebastián Lerdo de Tejada (1890). Se presenta, además, una red de complicidad y alianzas entre este y otros periodistas mercenarios del periodo, contemporáneos y cómplices periodistas, como José Negrete (1855-1883) y Salvador Quevedo y Zubieta (1859-1935). Siguiendo de cerca las teorizaciones que sobre el libelo ha hecho el historiador Robert Darnton, se contextualiza su impacto y circulación en la coyuntura política del fin de siglo xix en México. Se observa el libelo como un modelo textual flexible que sigue el ritmo y el tiempo inmediatista de la prensa y se vale de ésta y de sus estrategias para circular y construir un público ávido de morbo y escándalo en el terreno de la esfera pública y que toma muchas veces la forma de géneros literarios prestigiosos y con audiencia. Se desmonta y cuestiona la idea de la prensa de oposición del periodo estudiado gracias a obras literarias cuya intención diluye los pactos de veracidad y rechazo al régimen.

Introduction. The authors study the cultural heritage site that somehow shapes the architectural appearance of the Musin-Pushkin estate, located at the intersection of Dobroslobodskaya and Spartakovskaya streets in Moscow (now this group of buildings accommodates the Moscow State University of Civil Engineering); it is the north wing of the architectural ensemble in the northern corner of the estate along the frontage line of Spartakovskaya street. This building is a cultural heritage site of federal significance; it’s interiors and facades have undergone numerous renovations and reorganizations. The main purpose of this work is to trace the history of this wing by analyzing it in the context of surrounding buildings, identify the initial appearance of this monument, track the periods of its construction, and, as a result, propose its graphic reconstruction, that will encompass not only its earliest period, but also the stage when its architectural form was changed to something new but not less interesting.
Materials and methods. The method of comprehensive research was employed to study the monument. This method encompasses a search for and analysis of sources and literature, field studies, including probing, pit boring and taking measurements, as well as the chemical analysis of building and finishing materials. The comparative method was used to match this construction facility against other stylistically and typologically similar buildings.
Results. As a result of the studies, the monument’s construction periodization was traced, the dates of its present-day appearance were identified, initial elements of the building were identified and studied, its further changes were traced to make a graphic reconstruction of the north wing since its very first days.
Conclusions. The proposed reconstruction of the monument is a result of its comprehensive study needed to reconstruct the initial appearance of the building, including its missing parts. This project will allow tracing the history of the architectural appearance of a most interesting manor estate in Moscow.

Architecture aware compilation of quantum circuits via lazy synthesis
Authors: Martiel Simon , Brugière Timothée Goubault de
Published: June 2022

Qubit routing is a key problem for quantum circuit compilation. It consists in rewriting a quantum circuit by adding the least possible number of instructions to make the circuit compliant with some architecture's connectivity constraints. Usually, this problem is tackled via either SWAP insertion techniques or re-synthesis of portions of the circuit using architecture aware synthesis algorithms. In this work, we propose a meta-heuristic that couples the iterative approach of SWAP insertion techniques with greedy architecture-aware synthesis routines. We propose two new compilation algorithms based on this meta-heuristic and compare their performances to state-of-the-art quantum circuit compilation techniques for several standard classes of quantum circuits and show significant reduction in the entangling gate overhead due to compilation.

Citra suatu organisasi tercermin dari baiknya penyusunan administrasi organisasi yang melibatkan kepemimpinan, kebijakan, dan hubungan antar manusia. Kegiatan administrasi mencakup kegiatan pengendalian informasi yaitu tulis menulis/mencatat, menggandakan, menyimpan, dimana kegiatannya bertransformasi menjadi lebih praktis dan transparansi pada era digitalisasi. Program studi sebagai bagian dari perguruan tinggi menghadapi kompleksitas administrasi Tugas Akhir (TA) mahasiswa yang menimbulkan beberapa permasalahan antara lain human error, keberagaman formating berkas, komunikasi panjang dan koordinasi bertingkat antar unsur dalam perguruan tinggi jika proses administrasi tersebut dikerjakan secara manual. Permasalahan berdampak pada terganggunya pengambilan keputusan.  Akan tetapi hal tersebut dapat diminimalisir dengan pendigitalisasian administrasi TA mahasiswa berbasis web dengan teknologi MEAN (MongoDB, Express, Angular, dan NodeJS) stack menggunakan metodologi kombinasi antara Traditional Iterative model dengan Scrum model.  Pemanfaatan modern teknologi MEAN STACK mengakomodir administrasi TA sebagai sebuah SPA (Single-Page Application) yang menggunakan  bahasa pemrograman JavaScript baik dari client-side maupun server-side. Upaya ini dilakukan agar perangkat lunak yang dihasilkan dapat lebih adaptif atas perubahan sistem, namun biaya pengembangan terjangkau dan pengendalian dapat dilakukan pada setiap tahap secara transparan dalam sebuah tim kerja kecil.

Information technology in recent years has become an absolute necessity, for all levels of society, especially the government, to support the exchange of information that is fast, easy, accountable, and has good service. BPKAD is one of the SKPDs in the NTB Province Government in charge of managing regional finances and assets that already have a computer network that mostly implements wireless-based applications, which are less than optimal for internet connections and information exchange so that they are not optimal in public services. Based on these problems, the researchers designed a computer network infrastructure that can be integrated between buildings at the BPKAD Office and other SKPD in the NTB province government. The design results presented can be used as considerations in order to support the development of e-government implementation. The network model used is the NDLC hierarchy and methodology. With a computer network, it can minimize connection constraints and be more optimal in bandwidth management, install filtering firewalls, limit users with negative content.Keyword: BPKAD; SKPD; E-Gorverment; NDLC; Bandwidth

In order to control NOx in low-temperature flue gas in non-power
industry and reduce the preparation cost of denitration catalyst. Using
low-value solid waste, blast furnace slag, as raw material. After
cooling, drying and grinding, the blast furnace slag becomes a powder
with considerable fineness and meets the requirements of activity index,
which is called GGBS (ground granulated blast furnace slag). Using GGBS
as denitration catalyst carrier, and the active component n (n = Fe, Co,
Ni, Cu and Ce) was loaded on Mn-based GGBS catalyst by impregnation
method. It was studied that the effects of different active components
on denitration and sulfur resistance of Mn-based GGBS catalyst. The
denitration mechanism was analyzed by BET (Brunner-Emmet-Teller
measurements), XRD (X-ray diffraction), XPS (X-ray photoelectron
spectroscopy), SEM (scanning electron microscope) and FT-IR (Fourier
transform infrared spectroscopy). The results show that: Mn-Ce/GGBS
catalyst has better denitration and sulfur resistance.

Tetralogy of Fallot Associated with a Rare Type Partial Anomalous Pulmonary Venous Return
Authors: Lee Won Young , Shin Ju Ae , Kang Nu-Ri
Published: June 2022

Tetralogy of Fallot (TOF) is rarely associated with partial anomalous
pulmonary venous return (PAPVR). Unidentified PAPVR, however, might
increase the risk of pulmonary valve replacement in repaired TOF
patients by right ventricular (RV) dilatation and RV dysfunction. Here,
we present a case of a 19-year-old male who received a correction of TOF
18 years ago and a rare type of PAPVR was identified during the follow
up period. The anomalous pulmonary veins were connected to the left
hepatic vein, left superior vena cava, and the right superior vena cava.
Performing a pulmonary valve replacement, PAPVR was also corrected by an
intra-atrial baffle with a new approach using the venous plexus between
the left hepatic vein and the right hepatic vein.

Published: June 2022

Background We evaluated short- and mid-term outcomes with use of aortic
valve-sparing root replacement to treat bicuspid aortic valves. Methods
From December 2007 to January 2022, all patients with bicuspid aortic
valves who underwent aortic root replacement using Tirone’s procedure
were included. This study based on department database information for
retrospective and follow-up data. Results Among 51 adults undergoing
aortic root replacement using Tirone’s procedure, the mean age was
47.4±12.5 years, and most were men (92.2%). Three presented with a
dysmorphic syndrome and one had Marfan’s syndrome. All patients were
alive at 30 days, and as of January 2022, 45 were alive, two were lost
to follow-up, and there were four noncardiac deaths. Two patients had
infectious endocarditis and needed a Bentall’s procedure. One patient
had a double biologic valve replacement in the context of severe mitral
insufficiency with moderate aortic stenosis at 4.5 years post-procedure.
Echocardiographic follow-up showed a left ventricular ejection fraction
of 63±7% (n=36), V 2±0.6 m/s (n=17), and a mean
gradient of 9.4±5.4 mmHg (n=27). No patients had grade 3 or 4 aortic
regurgitation, one patient had grade 2, and four had grade 1. Conclusion
Tirone’s procedure is an option for bicuspid aortic valve surgery, with
good safety and outcomes, especially in younger patients.
Techniques and Pitfalls of Coronary Arterial Reimplantation in Anatomical Correction of Transposition
Authors: Chowdhury Ujjwal , Anderson Robert , Spicer Diane E. , Sankhyan Lakshmi , George Niwin , Pandey Niraj , Goja Shikha , Chandhirasekar Balaji
Published: June 2022

Backgroundand Aim: We assessed the anatomical
variations in coronary arterial patterns relative to the techniques of
reimplantation in the setting of the arterial switch operation, relating
the variations to influences on outcomes. Methods: We reviewed
pertinent published investigations, assessing events reported following
varied surgical techniques for reimplantation of the coronary arteries
in the setting of the arterial switch procedure. Results: The
prevalence of reported adverse events, subsequent to reimplantation,
varied from 2% to 11%, with a bimodal presentation of high early and
low late incidence. The intramural pattern continues to contribute to
mortality, with some reports of 28% fatality. The presence of abnormal
course relative to the arterial pedicles in the setting of single sinus
origin was associated with a three-fold increase in mortality. Abnormal
looping with bisinusal origin of arteries was not associated with
increased risk. Conclusion: The techniques of transfer of the
coronary arteries can be individually adapted to cater for the
anatomical variations. Cardiac surgeons, therefore, need to be familiar
with the myriad creative options available to achieve successful repair
when there is challenging anatomy. Long-term follow-up will be required
to affirm the superiority of any specific individual technique. Detailed
multiplanar computed-tomographic scanning can now reveal all the
variants, and elucidate the mechanisms of late complications. Coronary
angioplasty or surgical revascularization may be considered in selected
cases subsequent to the switch procedure.
H63D syndrome (Oslo Syndrome) is clinically the iron sibling of Wilson's disease
Authors: Diamandis Dr. Carolina , Wilson Jonathan , Ivanova Olga , Seideman David
Published: June 2022

H63D syndrome, now clinically known as Oslo syndrome (synonymous), is
considered a very rare disorder that is difficult to recognize due to
its multifaceted nature. Even with homozygous mutation of the HFE gene
H63D and the simultaneous presence of the typical clinical symptoms, few
clinicians dare to care for affected patients. This is inexplicable,
because Oslo syndrome (H63D syndrome) looked at on the meta-level is
nothing more than Wilson disease caused by NTBI iron.
Utility of Transesophageal Echocardiogram Surveillance after Watchman Device Placement
Authors: Wu Stephanie , Minhas Harjit , Shiota Takahiro , Siegel Robert J. , Rader Florian
Published: June 2022

Background: In atrial fibrillation patients undergoing left atrial
appendage occlusion with a Watchman device, surveillance imaging with a
transesophageal echocardiogram (TEE) is typically performed at 45 days
and 1 year to evaluate for device-related thrombus (DRT) and peri-device
leak (PDL) before cessation of oral anticoagulation. The incidence of
these complications is relatively low, and the ideal timing and duration
of surveillance is unknown. We sought to evaluate the incidence of DRT
and PDL after Watchman placement at 45 days and 1 year to determine the
necessity of surveillance TEEs. Methods: We retrospectively analyzed 361
patients who received a Watchman device between January 2016 and January
2020. Baseline clinical and echocardiographic data, post-procedure
antithrombotic therapy and surveillance echocardiographic data were
collected from the NCDR LAAO Registry. Nested backward variable
elimination regression was performed to derive independent predictors of
the composite outcome of DRT and PDL. Results: A total of 286 patients
who had post-procedure TEEs were included in the analysis. At 45 days, 9
patients had DRT (3.2%) and 44 patients had PDL (15.0%). At 1 year, 5
patients had DRT (5.6%) and 8 patients had PDL (8.9%). All DRT at 45
days was treated with continued anticoagulation while no change in
protocol occurred with PDL. All DRT at 1 year occurred in new patients
without prior thrombus. A history of prior transient ischemic attack
(TIA) and thromboembolism were significantly associated with DRT or PDL
at 1 year. Conclusions: We identified several patients with
device-related complications at 45 days and 1 year despite appropriate
device sizing and adequate use of antithrombotic therapy. The incidence
of DRT increased from 45 days to 1 year and occurred in patients without
prior thrombus. These findings highlight the importance of surveillance
imaging and suggest the potential need for extended surveillance in
select patients.

Although Mo-dependent nitrogenase and synthetic molecular complexes have
attracted widespread attention in electrochemical nitrogen reduction,
the activity of Mo-based catalysts for nitrogen reduction is low.
Herein, molybdenum oxide nanoparticles were supported on
charge-modulated conjugated triazine frameworks (Mo/CTF-I) via ion
exchange reaction. Compared with Mo/CTF, the modified Mo/CTF-I maintains
high specific surface area and microporous structure after metal loading
and thermal treatment, and exposes high density MoOx as active sites.
This strong interaction between MoOx and CTF-I induces the electron
transfer from Mo to support to form MoOx with a valence state of 5+ and
lowers the energy barrier to transfer the donated electrons to the empty
anti-bonding π orbitals of N≡N. Electrochemical measurements proved that
5% Mo/CTF-I exhibited the highest NRR activity with a faradaic
efficiency of 27.3% and an NH3 yield rate of 7.23 mg h-1 gcat.-1 at
-0.405 V vs. RHE.

The deadly virus COVID-19 has affected not only the health of people but also the food value chain sector. The experience of the locked down period to curtail the spread of the virus was unexpected. It is therefore important to understand how small-scale farmers survived the period. This study examined the strategies employed by small-scale farmers in Osun State to adapt to the challenges resulting from COVID-19 lock down. Specifically, the study itemized types of crops grown by small-scale farmers, assessed the forms of challenges they faced during the COVID-19 pandemic, examined the perceived effects of these challenges on small-scale farming activities, and investigated the adaptation strategies employed by small-scale farmers during this time. Six communities in the local government were selected at random and a total of one hundred and twenty farmers from the communities were interviewed. A questionnaire was designed to collect the primary data. The data was analysed using descriptive statistics and the chi-square tools. Results showed that COVID-19 lock down period led to poor health status (mean=2.87), less transport available to convey farm produce (mean=2.70), and high cost with little/no access to farm inputs such as fertilizer, chemicals and seeds/seedlings (mean=2.62). The foremost effects of these challenges on small scale farming activities were poor marketing of agricultural produce (mean=4.52), decrease in farmers’ income (mean=4.51), and labour shortage (mean=4.39). The leading adaptation strategies employed by the farmers were planting of available grains instead of seeds (mean=2.85), reduced food consumption (mean=2.83), and the use of family labour (mean=2.80). The regression analysis showed that education (β=0.151), marital status (β =1.173), non-farm income (β=-6.790), and years of experience (β=-0.032) were significant (at p<0.05) factors influencing the adaptation strategies employed by the farmers. To effectively reduce the adverse effects of unexpected lockdowns on farmers in the future, it is recommended that outlets for necessary agricultural inputs should be made available in all farming communities

Published: June 2022

Febrile neutropenia is a serious adverse effect of chemotherapy. It can lead to complications and death, as well as delays in treatment, chemotherapy dose reductions, compromised treatment efficacy, and reduced survival. The assessment of the patient-related risk factors plays a significant role in the prevention of febrile neutropenia and its complications. In the case of intermediate-risk chemotherapy, the patient-related factors contribute to the estimation of an overall febrile neutropenia risk as well as to timely planning of primary prophylaxis using growth factors. Patients presenting with febrile neutropenia undergo a detailed initial risk assessment for serious complications so that an appropriate treatment can be selected. Recommendations given by the guidelines outline the classification of and risk factors for febrile neutropenia complications. The use of patient-related factors and validated tools for the risk assessment of complications makes it possible to optimize the treatment for each patient and to reduce the risk of morbidity and mortality due to febrile neutropenia.

Authors: Peric Dejan , Ruzic Jovana , Levic Steva , Stasic Jovana
Published: June 2022

Introduction/Objective. The objective was to determine the degree of conversion (DC), cross-link density, percentage of leachable monomers, flexural strength (FS), and hardness (HV) of nanohybrid, nanofilled bulk-fill, giomer, fiber-reinforced, and low-shrinkage composites. Methods. Standardized specimens (n = 5/group) of Tetric EvoCeram Bulk Fill, Filtek Bulk Fill, Beautifil, EverX posterior, Kalore, Filtek Z250 (microhybrid control), and Tetric EvoCeram (nanohybrid control) were subjected to micro-Raman spectroscopy, three-point bending, and HV. Cross-linking density and leachable monomers were ascertained based on the ratio of HV and DC before and after immersion in absolute ethanol. Results. DC was in the range 50.4?70.5%, the highest for Filtek Bulk and the lowest for Kalore. The highest %DC change was in Beautifil (10.3%) and the lowest in Filtek Bulk (1.4%) and Z250 (1.28%). FS ranged between 78.9 MPa (TEC) and 126.7 MPa (Filtek Bulk). HV ranged between 58.6 (Kalore) and 113.9 (Z250) and significantly decreased post-immersion (19?55%). HV48h inversely correlated to HV% loss (r = -0.761), whilst DC positively correlated with FS (r = 0.893). Conclusion. Filtek Bulk, EverX, and Z250 showed the highest DC. The lowest DC and mechanical properties were observed for Kalore. The greatest cross-link density was shown by Filtek Bulk. There were up to 10% of leachable monomers. DC and FS positively correlated.
The Independence of Independents: Influences on Commercial Driver Intentions to Commit Unsafe Acts
Authors: SWARTZ STEPHEN M. , DOUGLAS MATTHEW A.
Published: June 2022

Modern American folklore describes independent owner-operator truckers as the last cowboys or frontiersman. If accurate, the individualistic nature of the independent trucker would mitigate the effectiveness of “corporate culture” in modifying behavioral intentions. The modern independent owner-operator exists in a unique environment characterized by high regulation and low supervision, with highly undesirable consequences for bad decisions. This study used owner-operators' perceptions of carrier safety climate and the Theory of Planned Behavior (Ajzen 1991) to understand drivers; intentions to engage in potentially unsafe driving behavior. The relationships were tested with data from nearly 300 owner-operators who conduct national, regional, and local driving operations. Results supported the individualistic nature of owner-operators. Results also indicated that a carrier's use of supportive (versus directive) safety practices, combined with drivers' attitudes towards and perceived behavioral control of unsafe driving, significantly and directly influenced drivers' intentions to commit unsafe driving actions. These key findings inform carriers about adopting more resourceful safety training and awareness programs that provide drivers the necessary tools and skills to drive safely and avoid potential danger outside their control.

Published: June 2022

The authors update prior studies that evaluated the publication output of faculty members in refereed logistics, supply chain management, and transportation journals to identify current trends and changes. In addition a new weighted average metric is used to allocate credit to universities for co-authored articles. The rankings among the top-tier schools show comparable changes to prior periods in terms of the number of new entrants to the top twenty-five ranked universities. However, for the first time, non-North American universities have entered the top five rankings, indicating the increased global interest in and importance of logistics and supply chain management publications.
How Online Vendors Select Parcel Delivery Carriers
Authors: LIN PEI-CHUN , LEE CHIA-HUI
Published: June 2022

This study investigated what criteria online vendors use to select parcel delivery carriers and examines what bearing they have on the development and maintenance of mutually beneficial partnerships. The selection attributes are identified via the logistical transport literature and then grouped according to their influence on online vendors. Seven distinct factors pertaining to the selection of carriers were identified, the two most important of which are “on-time, tracking and quick response” and “fare rate and freight loss.” Considerable interpenetration is discernible between these factors and the e-commerce business model, average monetary transaction and shipment frequency. Online transactions reply on a distribution service that ensures physical goods reach intended customers. Since service requirements fluctuate over time, selection attributes identified in previous studies are likely to be of limited utility. An expanding online market affords more distribution service opportunities, which makes it imperative that key factors affecting the selection of carriers by online vendors are amenable to empirical verification.
Locating Manufacturer Distribution Centers by a Fixed-Charge Model: A Case Study of Kinmen Kaoliang Liquor Inc.
Authors: HUANG KUANCHENG , CHEN YING-HSUANN
Published: June 2022

Kinmen Kaoliang Liquor Inc. (KKL), once a nonprofit government monopoly, was corporatized in 1998. Cost reduction and profit maximization became the new corporation's main goal. Located on an island off the main island of Taiwan, KKL sells over 90 percent of its produced liquor domestically. In order to restructure its distribution system, KKL is planning to establish the distribution centers (DCs) on the main island of Taiwan. This study aimed to provide the decision support from a quantitative aspect for KKL's strategic plan. The classic fixed-charge model was modified to take into consideration the inbound and outbound transportation costs of the DCs as well as the variable and fixed components of the DC facility costs. This study collected and estimated the relevant parameters in the model, and obtained the optimized solution. The results indicated that three DCs need to be established with a total system cost of NTD 110,786,400 per year.
