El presente trabajo se realizó con el objetivo de comprobar la dureza que contiene el agua potable suministrado por la EPS EMAPA HUACHO S.A al distrito de Huacho; la gran mayoría de pobladores se habrán percatado que cada vez que hervimos el agua en casa, se observa la presencia de sólidos blanquecinos en suspensión, si bien es cierto la OMS no impide que las empresas que suministran agua para el consumo humano, abastezcan con una dureza que puede llegar hasta 500ppm, solo porque no se ha determinado puntualmente que la dureza cause alguna enfermedad con pruebas científicas; en cuanto a los metales pesados se tiene conocimiento que pueden acumularse en el organismo vivo y causar enfermedades como cáncer, vómitos, diarreas y otros.Para analizar el agua se realizó un trabajo conjunto con la empresa en la toma de muestras de los dos pozos que abastecen a la ciudad de Huacho el pozo Nº 03 y pozo Nº 09, utilizando el laboratorio de la facultad de Ingeniería Química y Metalúrgica para realizar los análisis por nuestra parte y así poder contrastar con los resultados de los análisis que la empresa EMAPA HUACHO.Mediante la comparación de los resultados obtenidos en ambos laboratorios, se puede comprobar que en el pozo Nº 03 existe solo un diferencial de 1,4 mg/L y en el pozo Nº 09 un diferencial de 1,6 mg/L, diferencias que se pueden ser aceptables para nuestra investigación. Además se puede realizar también una comparación con el mes de Abril, mes que tiene una ligera alza en ambos pozos que hubiera preocupado si hubiera sido lo contrario. En conclusión los pozos que abastecen agua potable a la ciudad de Huacho se encuentran dentro del rango que la OMS lo da como permisible.Palabras claves: Dureza, pozos, parte por millón.
Modelo Teórico de la Célula

Este artículo se enmarca en el ámbito de la justificación del marco teórico que la biología requiere para comprender el carácter sistémico de sus objetos de estudio, así como, de conjeturar acerca de las posibles relaciones que existe entre el todo y las partes con la finalidad de proponer nuevas líneas de investigación. Recordemos que a inicios del siglo XX, la Biología fue fuertemente criticada por el Círculo de Viena, Por carecer de leyes, y tener un empobrecido grado de matematización en sus sistemas de clasificación y la imposibilidad de falsar muchas de sus hipótesis. (Lorenzano, 2001; 2002). Piaget (1979) expresó en su libro Introducción a la epistemología genética que: “Al igual que la físico-química, la biología clasifica los objetos sobre los que trabaja, dilucida sus relaciones en forma de leyes e intenta explicar causalmente estas clasificaciones y leyes. Sólo que la estructura de estas clases en lugar de alcanzar en todos los casos y con mayor o menor facilidad un nivel matemático, conserva a menudo un carácter cualitativo, o simplemente lógico”. Inmediatamente como una respuesta a este rechazo en el año 1932 se formó en Cambridge un grupo de investigadores con el nombre de "Biotheoretical Gatherings" o también "Theoretical Biology Club", y cuyos participantes principales fueron J. H. Woodger, J. Needham, C.H. Waddington, D. M. Wrinch, J. D. Bernal. Woodger, naciendo así la Biología Teórica, como un campo que defiende la necesidad de esclarecer los fundamentos teóricos de la biología. Desde su origen se destaca por preocuparse especialmente del problema de la organización biológica y por la elaboración de herramientas metodológicas (primero matemáticas, después también computacionales) para su tratamiento científico. Según Hempel (1965), la explicación parte de una declaración de un fenómeno a ser explicado y encuentra un conjunto de leyes ()nLLL,......,21y enunciados ()nEEE,.....,21en los hechos antecedentes ()nAAA,........,21 que implican una declaración. Lorenzano (2001), destaca que la Biología carece de unicidad en el lenguaje, lo que es relativamente frecuente para numerosas ciencias: “En lugar de encontrarnos con un único lenguaje que nos permita expresarlas [a las ciencias biológicas], nos encontramos con una gran variedad de lenguajes específicos a ciertas subdisciplinas o teorías biológicas, lo cual no elimina la posibilidad de que éstos se relacionen de algún modo entre sí”.

Objetivo: Determinar metales pesados en mariscos comercializados en el Puerto de Huacho y así mismo estimar el riesgo de exposición por consumo. Métodos: Se estableció el consumo semanal de Stramonita chocolata, Aulacomya ater, Fissurella limbata y Platyxanthus orbignyi,a través de la aplicación de una encuesta a 100 individuos residentes en el distrito, con lo cual se calculó el riesgo de exposición al plomo (Pb), arsénico (As), cadmio (Cd) y mercurio (Hg); se registró la procedencia de las muestras, se inspeccionaron, codificaron y transportaron en bolsas dentro de coolers con hielo, se acondicionaron y se extrajo la pulpa que luego fue congelada durante 12 horas. Se analizó en los laboratorios de Certificadora del Perú (CERPER) según la NOM- 117-SSA1-1994. Resultado: Las concentraciones de Hg halladas en A. ater, S. chocolata, F. limbata y P. orbignyifueron menores de 0,5 mg/Kg; el As en todas las especies, fue menor al límite máximo permisible de 5,0 mg/Kg; en todas las muestras el Pb se mantuvo por debajo de 1,5 mg/Kg (para A. ater, S. chocolata, F. limbata) y 0,5 mg/Kg (P. orbignyi). El Cd superó el límite máximo permisible de 1.0 mg/Kg en A. ater, S. chocolata, F. limbata, mientras que en el P. orbignyi se mantuvo debajo del límite (0,5 mg/Kg). Conclusión: Tras el análisis con estadístico se determinó que el Cd es el metal pesado más abundante, de mayor porcentaje de consumo y que representa un riesgo de toxicidad por la ingesta de S. chocolata de 0.030 a 0.060 Kg /Semana.Palabras Claves: Ingesta semanal tolerable provisional (ISTP), metales pesados, mariscos, límite máximo permisible (LMP)
Integrated Marketing Communications in Contexts of Eco Tours in Porto (Portugal): Challenges (Post) Covid-19
Authors: Barbosa Sousa Bruno
Published: January 2021

In the face of an increasingly competitive and global market, where communication channels are massified and where information sharing between consumers occurs in such a fast and uncontrolled way, brands need to reinvent their communication plans, with the aim of focus on the emotional side of the consumer. Thus, in this context, the integrated communication mix emerges as a competitive strategy to meet the needs of consumers. Therefore, the main objective of this chapter is to understand the role of the Integrated Marketing Communications in the context of an organization linked to ecological tours. This chapter presents contributions to the area of marketing and communication (integrated), tourism (ecological) and a response to the pandemic and post-pandemic scenario (i.e., covid-19), at the level of response strategies in the context of a pandemic in 2020 (through digital communication channels). A qualitative methodology was adopted, using semi-structured interviews with organizational managers in the context of ecological tours in Portugal (i.e., Ekoeasy case study). Ecotourism as a concept is neither easy to define, nor to implement. Ecotourism is a complex concept as it involves specialised niche markets that can share a lot of characteristics, preferences and motivations or vary for the same reasons. Future studies should allow to complement the present investigation, through empirical study and quantitative nature (i.e., questionnaires to tourist consumers in the North of Portugal).

Authors: Kuladeep Kumar L.
Published: January 2021

Since the outbreak of the novel SARS-CoV-2, machine learning and artificial intelligence (ML/AI) have become the powerful marketing tools to mitigate economic activities during COVID-19 pandemic. The goal of ML/AI technology is to provide data and insights so that brands can understand what’s working and what’s not. This will help marketers understand and anticipate what sort of communications work and how to deliver them. Therefore, these are such promising methods employed by various marketing providers. AI uses machine learning to adapt and make changes which impact marketing in real time. The exact impact of events such as the COVID-19 pandemic is hard to predict, but AI will help us track and anticipate these circumstances, as well as provide us with the data needed to proceed. This chapter deals with recent studies that use such advanced technology to increase researchers from different perspectives, address problems and challenges by using such an algorithm to assist marketing experts in real-world issues. This chapter also discusses suggestions conveying researchers on ML/AI-based model design, marketing experts, and policymakers on few errors encountered in the current situation while tackling the current pandemic.
UNA NUEVA MIRADA AL MESIANISMO ANDINO
Authors: Millones Luis
Published: January 2021

Este trabajo aborda tres casos de mesianismo en los Andes: El taki ongoy de 1565; Illapa: El mesías de Huancavelica de 1811; y el mito de Inkarrí descubierto en 1955. El mesianismo involucraba una esperanza colectiva que se esperaba que se realizase en este mundo, que acaecería en corto tiempo y que transformaría a la sociedad y que se llevaría a cabo con intervención de lo sobrenatural. El taki onqoy que, apareciendo en la jurisdicción de Huamanga, especialmente entre los Soras y Lucanas, rechazó a lo occidental y pregonó la reinstauración del sistema prehispánico. Pedro Alanya en Lircay se autoproclamó “pongo” de Santiago Apóstol o Illapa y promovió entre sus seguidores el retorno de los antiguos rituales de propiciación para atraer lluvias y superar la sequía que venía provocando hambrunas en los nativos. El Inkarrí mitificó la muerte del inca que, a partir de su cabeza, iba creciendo su cuerpo para retornar. Versiones más recientes hicieron notar que los mitos no son ajenos a la realidad y que se adaptan a la experiencia de la que son testigos sus creadores, porque se  habla que el inca fue degollado y “volado” (con dinamita).

Râu hùm (Tacca chantrieri Andre) là loài cây thuốc quý, có công dụng chữa bệnh thấp khớp, dùng uống trị viêm loét dạ dày và hành tá tràng, viêm gan, huyết áp cao, bỏng lửa, lở ngứa…[7,10]. Mặc dù chưa bị khai thác nhiều quá mức song nạn phá rừng và khai thác rừng đã trực tiếp làm thu hẹp diện phân bố và khả năng trữ lượng tự nhiên của cây. Việc nghiên cứu nhân giống loài Râu hùm nhằm bảo tồn và phát triển các loài cây thuốc của tỉnh Tuyên Quang. Kết quả nghiên cứu nhân giống Râu hùm bằng phương pháp sinh dưỡng cho thấy, hom giâm ở các vị trí hom khác nhau (hom ngọn, hom giữa và hom gốc) có kích thước 10cm cho tỷ lệ sống cao hơn, trong đó hom giữa (kích thước 10cm) sau 30 ngày, 60 ngày và 90 ngày đều cho kết quả cao nhất với các giá trị tương ứng về tỷ lệ hom sống (95,9%, 78,5% và 67,8%). Hom giữa (10cm) cho số chồi/hom cao nhất. Khi nhân giống Râu hùm bằng hom giữa (10cm) có sử dụng các chất kích thích sinh trưởng và nồng độ sử dụng các chất đó tới tỷ lệ sống và ra rễ cho thấy: sau 90 ngày, công thức cho tỷ lệ sống cao nhất là hom xử lý IAA với nồng độ 1500ppm đạt 100%, cao hơn nhiều so với đối chứng. Tiếp đến là IBA với tỷ lệ 98,5%, còn lại α-NAA có sự tác động lên hom giâm thấp nhất. Loại chất kích thích sinh trưởng và nồng độ sử dụng đã ảnh hưởng rõ rệt đến tỷ lệ ra rễ và số rễ trung bình/hom, khi nồng độ tăng từ 500ppm lên đến 1000ppm, đặc biệt lên đến 1500ppm thì tỷ lệ ra rễ và số rễ trung bình/hom có xu hướng tăng theo. Công thức 9 với chất kích thích IBA ở nồng độ 1500ppm cho tỷ lệ cao nhất.

An integrated model of financial well-being: The role of financial behavior
Authors: Iramani Rr. , Lutfi Lutfi
Published: January 2021

One of the main goals of every individual or household is to achieve financial well-being. Previous research has shown that various factors influence financial well-being. This research aims to develop an integrated family financial welfare model by examining various factors that affect it. This study uses data of 1,158 households taken using an online survey. The data is analyzed using a structural equation model. The results show that financial experience, financial knowledge, financial status, and marital status directly affect financial well-being. Financial behavior significantly mediates the influence of financial behavior, financial knowledge, and locus of control on financial well-being. Furthermore, marital status strengthens the effect of financial knowledge on financial well-being, but it does not strengthen the effect of financial experience on financial well-being. This study suggests that the Government and financial authorities need to improve further the effectiveness of financial literacy and financial inclusion programs and campaign for a more frugal life among households to avoid financial difficulties.

Published: January 2021

This paper examines the impact of corruption on employers' efficiency in Vietnamese firms. The Generalized Least Square (GLS) estimation method was used for data sets surveyed for Vietnamese firms in 63 localities. The research results show that the unofficial costs in the industry and the total informal costs accounting for 10% or more of revenue will negatively affect the labor efficiency of these enterprises. For costs related to administrative procedures, businesses accept to pay these fees in order to save waiting time and it contributes to increase the efficiency of employers in businesses. In addition to the corruption factor, the study also shows that the number of employees, the location of operation, the average value of fixed assets per employee and the return on equity also affect the efficiency of use. employees in Vietnamese enterprises.
Profitability of energy sector companies of Saudi Arabia: Mutual analysis based on revenue and investment
Authors: Ali Anis , Alam Mohammad Zulfeequar
Published: January 2021

The profitability of the business organization is the relative measurement and explores the profit earning capacity. There are two concepts of measuring profitability, which are profitability based on revenue, and investments. Gross and net profitability are the means of expression of the profitability based on revenue while investment profitability can be measured based on owners’ investment and total investment or total assets. Secondary data from the websites of the energy sector companies are taken for the study and ratio analysis, rank correlation is applied to get the similarity or differences in the profitability and relational relationship of the energy sector companies of Saudi Arabia. The study reveals that there was a significant difference in the profitability of the energy sector companies. Possibly, internal and external factors of the business organizations govern the profitability. There is a perfect and positive relational correlation between revenue and profitability while a highly negative correlation exists between profitability and investments. This may be due to overcapitalization or underutilization of the resources. Enhancement of velocity of operational activity is necessary to enhance the operational level of energy sector companies of Saudi Arabia. There is a need to control the indirect manufacturing and administrative expenses in smaller organizations and further investment in the energy sector companies is not advisable.

Tests on structural concrete beam-column joints with intermediate column bars
Authors: Park R. , Keong Yeoh Sik
Published: January 2021

Three structural concrete interior beam-column joint units were tested. The beams were prestressed by tendons in the top and the bottom of the section but not at mid-depth. The columns were reinforced using Grade 380 longitudinal bars. Transverse shear reinforcement existed in all members and in the joint core. Static cyclic loading was applied to the units to simulate seismic loading. The presence of intermediate column bars was shown to significantly improve the shear capacity of the joint core, and the need for a relatively small neutral axis depth in the plastic hinge regions of beams for ductile behaviour was emphasized.

An Exploratory Study of the Consequences of Perceived Organizational Prestige on a Range of Work Attitudes and Behaviors among Public Employees: A Call to Future Research
Authors: Bright Leonard
Published: January 2021

Government organizations in the United States routinely face harmful scrutiny from the mainstream media, politicians, and citizens. The messages from these sources communicate that many Americans are not happy with their government nor its public agencies. These sentiments are likely to lower the prestige of public organizations in the eyes of current employees and hamper retention efforts. However, there is a limited amount of empirical research that has explored the consequences of employees’ perceived organizational prestige (POP) perceptions in public organizations. This study seeks to fill this gap by exploring the direct association that POP perceptions have on a range of work outcomes for the purpose of stimulating future research on the topic. Based on a sample of federal employees working for the Department of Homeland Security in the United States, this study found that POP was significantly related to job and organizational satisfaction, commitment, self-reported performance, work related stress, and turnover intentions. The implications of findings for future research are discussed.

The paper shows that in the presence of silver nanoparticles the efficiency of intramolecular energy transfer in the complex of europium with doxycycline increases. It is proved that sensitivity of determination increases and limit of detection of doxycycline decreases by the method of sensitized fluorescence. The justification of the observed effects is given. The amplification of the signal of sensitized fluorescence in the presence of silver nanoparticles (energy donor) is the result of resonant transfer of excitation energy between the nanoparticle and the antibiotic ion, which is implemented under conditions of overlapping of the local surface plasmon resonance spectrum and excitation of the doxycycline ligand located near the surface of the nanoparticle. As a result of exposure to the antibiotic external radiation source and the local field of the surface plasmon increases the efficiency of tetracycline excitation, which contributes to the effectiveness of intramolecular energy transfer in europium chelate with doxycycline, doubling the intensity and lifetime. Modification of the surface of silver nanoparticles by europium ions allows to reduce the distance between the surface of a nanoparticle and an antibiotic, to increase the intensity of the signal of sensitized fluorescence by more than 100 times. The role of the stabilizer of a non-chromophore-containing ligand, − citrateion, in the formation of the analytical signal lies in its participation in the formation of a multi-ligand Eu3+ complex on the surface of a nanoobject, which reduces the distance between the donor and the acceptor, as well as the additional removal of water molecules from the immediate environment of the complexing agent ion, suppressing the process of excitation energy dissipation. On the basis of the conducted researches the fluorimetric technique of definition of doxycycline in medicines is offered. It differs in a low limit of detection (6.0·10-9 M) and a wide range of the defined concentrations from 1.0·10-8 to 1.0·10-5 M.

Authors: KADEROĞLU BULUT Çağrı
Published: January 2021

New social movements are one of the most discussed phenomena in social sciences since their emergence in the 1960s. These movements, which are considered as a reflection of the economic, political and social transformations experienced in contemporary societies, are discussed with their various characteristics and are subject to many theoretical approaches. This study examines the New Social Movements Theory, which is one of the most influential of these theoretical approaches. Two important names of the theory, Touraine and Melucci, evaluate new movements within the framework of post-industrial social theories and examine them in the context of transition from class-based movements to culture-identity-based movements. This approach lays the foundational idea of this theory. Elements such as the actors, goals, discourses, and organizational structures of the new movements are basically addressed on this ground and the differentiation between the new movements and the old movements is explained within this framework. This theory, which treats new social movements as a part of a new social construct, has been the subject of many criticisms. The analysis of this theory based on the post-industrial society and its explanation frames based on culture-identity have been criticized especially by Marxist approaches. Hence, this study examines the new social movements theory in the context of founding ideas, content, and criticism of the theory. In the study, firstly, the basic ideas of the theory in relation to social analysis are discussed, and then the approach of the movements towards the actors, values, goals and forms of organization is analyzed. Finally, the main criticisms of this approach are discussed. The main conclusion reached in the study is that the new social movements theory is insufficient to develop a comprehensive and accurate understanding of contemporary social movements.

Health communication is a field of study that has been included in the communication world since the 1970s. Health communication has a field of application carried out by individuals and media-mediated communication in health service delivery and health promotion. Health communication is an applied field of study because it examines both the pragmatic effects of human communication on the provision of healthcare and public health promotion and studies in this area are often used to improve the quality of healthcare delivery. Health communication campaigns are prepared to reveal desired health behaviors in society and to prevent risky health behaviors. However, whether these campaigns achieve their goals is an issue that is rarely discussed. Health communication and its applications at the mass communication level are realized through health communication campaigns. The success of a health communication campaign is measured by comparing the current situation before and after the campaign. This brings us to the concept of evidence-based health communication. This study describes the design stages of evidence-based health communication, which is an effective phenomenon in measuring campaign success. The similarities and differences among non- experimental, quasi-experimental and experimental designs were revealed in the study. The aim of the study is to explain the campaign design stages of evidence-based health communication and provide a guide to the pre-campaign preparation process for practitioners. Thus, practitioners will be able to choose the most suitable design for their target audience and avoid application mistakes.

Published: January 2021

There are complex nonlinear behaviors such as bifurcation and chaos in a single-phase H-bridge photovoltaic inverter under proportional integral control, which will increase the harmonic content of the output current greatly and reduce the stability of system operation and reliability of power supply. There are the problems suffering the complicated modeling and difficulty in determining the control coefficients in existing chaos control methods. The exponential delay feedback control is a further development of the delay feedback control, which has the advantages of requiring no precise mathematical model of the system and simple implementation. However, our research shows that when the exponential delay feedback control is directly applied to the system, the feedback intensity cannot be controlled, which will bring too big a disturbance to the system. Based on it, an improved exponential delayed feedback control method is proposed in this paper. Firstly, a feedback signal is formed by the difference between the output current of the system and its own delay, then the feedback signal is used to obtain the control signal through an exponential link, a subtraction link and an proportion link, and the control signal is applied to the controlled system in the form of a feedback. At the same time, the discrete mapping model of the system is established and its Jacobian matrix expression is determined. Finally, the limiting conditions of the feedback control coefficient of the control signal are derived based on the stability criterion, and the control is applied to the system. In order to verify the control effect of this method, a lot of simulation experiments are conducted. The results show that the problems that the exponential delay feedback cannot control the feedback strength and causes excessive disturbance to the system will be effectively solved by this method. When the bifurcation parameters vary greatly, the chaos behaviors in the system will be suppressed effectively, the stable operating domain of the system will be expanded greatly and the harmonic content of the output current will be reduced.

Plasma nanostructures are of particular significance for serving as a substrate for spectroscopic detection and identification of individual molecules. By combining the excitation wavelength of the molecule with the resonance wavelength of the nanostructure, the sensitive single-molecule Raman detection can be achieved. A high and stable plasma substrate for coherent anti-Stokes Raman scattering(CARS) is very useful for developing the surface-enhanced coherent anti-Stokes Raman scattering (SECARS). In the plasma nanostructures, the strong coupling of plasmonic nanoparticles with an inter-particle gap smaller than the diameter of the individual nanoparticles results in the hybridization of the optical properties of these individual nanoparticles. There are also the charge transfer plasmons(CTP) appearing in conductive bridging nanoparticles. Their unique properties make linked nanosystems a suitable candidate for building artificial molecules, nanomotors, sensors, and other optoelectronic devices. In this work, we, starting from reality, theoretically design a new linked nanosystem SECARS substrate where Fano resonance can be generated by the plasmon hybridization (PH) model resonance and the charge transfer plasmon resonance. The introduction of charge transfer plasma improves the tunability of structural resonance. By adjusting the conductivity of the conductive junction, the wavelength of the charge transfer plasma resonance can be easily adjusted to change the wavelength position of the Fano resonance. The data obtained by numerical simulation of the Raman mode at 1557 cm–1 of L-tryptophan when a 1064 nm light source is used as the pump light show that this spatially symmetrical structure can generate multiple high-enhancement hot spots that do not depend on the polarization direction of the incident light. Ordinary CARS signal can generally be enhanced by 1012, and its maximum can reach 1014. Due to the ultrastrong field enhancement and insensitive-to-polarization, this method of using charge transfer plasma to design a substrate can be used in the practical substrate of SECARS and provide new ideas for designing other nonlinear optical processes such as four wave mixing and stimulated Raman scattering.

In recent years, organic-inorganic hybrid perovskite solar cells (PSCs) have attracted wide attention due to their high photoelectric conversion efficiency and simple preparation process. Hole transport layer (HTL) is one of the most critical components in PSCs. As a kind of inorganic HTL material, nickel oxide (NiOx) has been widely used in perovskite solar cells because of its excellent advantages, such as outstanding chemical stability, high carrier mobility, simple methods for its preparation, etc. In this paper, the applications of NiOx HTL in planar PSCs are systematically summarized from the aspects of the improvment of its structure and photoelectric properties by doping and interface modification. The reasons for affecting the device performances, i.e. fill factor, open-circuit voltage, short-circuit current, photoelectric conversion efficiency, and stability are emphatically analyzed from several aspects, such as energy level matching, hole mobility and crystallinity. In addition, the future development directions of the planar PSCs are prospected.

Published: January 2021

Vegetable cultivation offers a unique opportunity for hill farmers of Uttarakhand due to the favourable climatic conditions. Consequently, vegetable cultivation in Uttarakhand hills, even in off-season, has picked up on quite a large scale. Although it has become quite remunerative but farmers are reportedly facing lots of marketing and production constraints. The present study was conducted in Kumaon region of Uttarakhand to study the production and marketing constraints faced by the vegetable growers. Study sample comprised of 200 farmers selected purposively from eight villages spread across four blocks and two districts in Kumaon division of Uttarakhand. The data was collected using a pre-tested structured interview schedule. The study findings revealed that major marketing constraints reported by vegetable growers were: long chain of intermediaries, inadequate transportation facilities, high transportation charges, inadequate storage facilities, low price / lack of remunerative price and non-availability of market information. Further, some production related constraints reported by the respondents were high cost of seeds/ fertilizers, lack of information about planting material/ production inputs, lack of knowledge about grading and standardization of vegetable, non-availability of farm labour and lack of packaging material. These findings will be helpful to the State government for developing a policy framework and relevant guidelines for promoting vegetable production in the state.

Human leukocyte antigen (HLA) genotyping gains intensive attention due to its critical role in cancer immunotherapy. It is still a challenging issue to generate reliable HLA genotyping results through in silico tools. In addition, the survival impact of HLA alleles in tumor prognosis and immunotherapy remains controversial. In this study, the benchmarking of HLA genotyping on TCGA is performed and a ‘Gun‐Bullet’ model which helps to clarify the survival impact of HLA allele is presented. The performance of HLA class I genotyping is generally better than class II. POLYSOLVER, OptiType, and xHLA perform generally better at HLA class I calling with an accuracy of 0.954, 0.949, and 0.937, respectively. HLA‐HD obtained the highest accuracy of 0.904 on HLA class II alleles calling. Each HLA genotyping tool displayed specific error patterns. The ensemble HLA calling from the top‐3 tools is superior to any individual one. HLA alleles show distinct survival impact among cancers. Cytolytic activity (CYT) was proposed as the underlying mechanism to interpret the survival impact of HLA alleles in the ‘Gun‐Bullet’ model for fighting cancer. A strong HLA allele plus a high tumor mutation burden (TMB) could stimulate intensive immune CYT, leading to extended survival. We established an up to now most reliable TCGA HLA benchmark dataset, composing of concordance alleles generated from eight prevalently used HLA genotyping tools. Our findings indicate that reliable HLA genotyping should be performed based on concordance alleles integrating multiple tools and incorporating TMB background with HLA genotype, which helps to improve the survival prediction compared to HLA genotyping alone.
