Authors: Коробейникова Лариса Сергеевна , Панина Ирина Викторовна
Published: April 2022

Цель: раскрыть роль аудита в сфере закупок как инструмента защиты охраняемых законом ценностей, уточнить его содержание в этом контексте. Обсуждение: в настоящее время реализуется реформа контрольно-надзорной и разрешительной деятельности в Российской Федерации. В основе реформы лежит идея эффективной защиты охраняемых законом ценностей посредством оптимизации государственного контроля (надзора), муниципального контроля. Цели контроля (надзора) должны быть обусловлены защищаемыми ценностями, масштабы и содержание контрольных мероприятий оптимизируются на основе риск-ориентированного подхода. Аудит в сфере закупок является формой внешнего государственного финансового контроля. Для него характерны общие проблемы этой системы, повлекшие необходимость ее реформирования: недостаточная конкретизация сущности, цели контроля, полномочий контролирующих субъектов, дублирование функций разных ветвей контроля, нечеткость и множественность нормативных требований и ряд других. В этой связи возникает вопрос о возможности применения в аудите в сфере закупок подхода к организации контроля, который является целевым в проводимой реформе контрольно-надзорной и разрешительной деятельности. Результаты: в целях постепенного преодоления указанных проблем предложены уточненные формулировки цели, объекта, предмета аудита в сфере закупок; показан порядок использования риск-ориентированного подхода к планированию контрольной деятельности органов аудита в сфере закупок, планированию мероприятий по аудиту в сфере закупок.

Authors: Капустина Ирина Александровна
Published: April 2022

Цель: разработка методических подходов к формированию информации о социальной составляющей устойчивого развития корпораций для принятия заинтересованными сторонами обоснованных экономических решений. Обсуждение: необходимость трансформации корпоративной отчетности обусловлена развитием требований инвесторов к подотчетности бизнеса и раскрытию стратегии корпорации о социальном благополучии заинтересованных сторон. В качестве структурных элементов отчетности об устойчивом развитии наряду с ключевыми показателями эффективности могут использоваться иные различные показатели, составляющие аспекты и подкатегории отчетности. Результаты: социальная категория отчета об устойчивом развитии корпорации наиболее широко представлена в Отчете об устойчивом развитии ((GRI) – Global Reporting Initiative) [1]. Подготовку публичной информации об аспектах отчетности об устойчивом развитии целесообразно осуществлять на основе форматов внутренней отчетности, формирующих содержание корпоративных стандартов учета и отчетности. Для раскрытия информации по подкатегориям отчетности, содержащим значительное количество аспектов, внутренние отчеты, подготовленные в виде таблиц, графиков, иных наглядных форм дополняются текстовыми пояснениями. Целесообразным является агрегирование информации, предполагающее объединение сведений оперативных отчетов в текущих, а текущих отчетов – в сводных. Для подготовки текстовых пояснений к публичной отчетности об устойчивом развитии используются внутренние аналитические отчеты, интерпретирующие информацию нефинансовой корпоративной отчетности.
Экономическая пандемия в туризме или влияние COVID-19 на отрасль
Authors: Сушкова Наталья Сергеевна
Published: April 2022

Цель: в статье представлен авторский взгляд на состояние туристской отрасли в период пандемии и ее влияние на дальнейшее развитие. COVID-19 нанес серьезнейший урон по всем отраслям экономики, но одной из наиболее пострадавших считается именно туризм. Правительство максимально приняло все возможные меры поддержки для спасения отрасли. Но ситуация с каждым днем ухудшается. С начала 2022 года наблюдается активный уход с рынка туроператоров, несмотря на открытие перспективных турнаправлений и возобновление работы. Наблюдается не только российская, но и общемировая тенденция, что позволяет считать проблему текущего состояния туризма «пандемией экономики туризма». Изучение аспектов данного нового явления стало целью настоящего исследования. Обсуждения: ситуация в туризме отражается и на общем уровне ВВП, ухудшает положение занятости населения и уровня заработной платы. Привычные эффективные инвестиционные стратегии подвержены постоянным изменениям и направлены на поддержание текущего состояния турпредприятий. Результаты: спрос переориентирован в сторону внутреннего туризма как по причине безальтернативности направлений, так и по причине постковидного восстановления.

Objetivo: Identificar possibilidades/condições de acessibilidade à pessoa surda sobre informações relacionadas à pandemia por coronavírus disponíveis na plataforma You Tube. Método: Estudo descritivo-exploratório analisou vídeos disponibilizados em sites oficiais do governo entre março/2020 a março/2021. Buscaram-se aspectos indicativos de acessibilidade na comunicação (Legendas e/ou Intérprete de Libras) nos conteúdos audiovisuais. Resultados: Dos 2.577 vídeos acessados, quase 60% apresentaram acessibilidade parcial (Libras ou legendas), aproximadamente 30% sem acessibilidade e, 9,8% apresentaram (legenda + Libras). Assim, a condição esperada à acessibilidade na comunicação (presença de legenda e Libras nos materiais audiovisuais) apresentou baixo percentual contrapondo-se ao elevado número de vídeos sem acessibilidade. Conclusão: Recursos audiovisuais são fundamentais na comunicação da pessoa surda e condições adequadas favorecem o acesso às informações circulantes nas plataformas de vídeos. A temática é relevante, mas ainda, pouco abordada necessitando outros estudos. Para além da pandemia, ampliarmos esta discussão visando reduzir e/ou eliminar barreiras comunicativas, é outra necessidade.
A relation between the quality of life of patients with epilepsy and adherence to treatment as well as retention on therapy
Authors: Lusnikova I. V.
Published: April 2022

Objective: to demonstrate  the mutual influence  of  the quality of  patients’s life  during  epilepsy, adherence  to received anticonvulsant therapy and retention on therapy.

Material and methods. We conducted an analytical review of studies published by foreign authors in recent years (published within 2016–2021  were considered of top priority), devoted to the influence of various factors on adherence to therapy in patients with epilepsy. A search for relevant publications was conducted in English-language databases (PubMed/MEDLINE, ClinicalKey) by using key words and phrases: “epilepsy AND quality of life AND adherence  to therapy”, “epilepsy AND quality of life AND retention on  therapy”,  “epilepsy AND adherence   to therapy”, “compliance AND epilepsy  AND quality of  life”, “adherence to therapy AND retention on therapy AND epilepsy”, “nonadherence to therapy AND epilepsy  AND quality of life”. After the selection procedure, 22 scientific publications were included in the review.

Results. Factors that have a negative impact on adherence  to therapy have been identified (comorbid cognitive impairment, the combination of lack of control over seizures and the presence of adverse events after drug administration, depression and anxiety, the need to change the lifestyle for taking the drug, concern about the potential negative consequences of taking the drug, recent uncontrolled seizures, lack of professional implementation, high frequency of taking the drug, problems with doctor-patient relationship, insufficient social support), and factors that have a positive impact (emotional support from the doctor, establishing doctor-patient partnership).

Conclusion. There is a relationship between the patient's quality of life and adherence  to therapy. Patient adherence to therapy is important for the effectiveness of epilepsy treatment and, along with the severity of epilepsy, is a significant factor affecting the quality of patients’ life during epilepsy. An opportunity for long-term retention on anticonvulsant therapy also has a cross-correlation with quality of life.
Quantitative assessment of regional pulmonary perfusion using three-dimensional ultrafast dynamic contrast-enhanced magnetic resonance imaging: pilot study results in 10 patients
Authors: Zakharova Anna V. , Prits Victoria V. , Pozdnyakov Alexander V.
Published: April 2022

Background. Currently there is a high demand in reliable noninvasive diagnostic technique assessing the physiological parameters of the lungs. We are exploring the three-dimensional ultrafast MRI sequence as a novel diagnostic modality allowing the assessment of regional quantitative perfusion parameters in pulmonary tissue.

Aim. To assess regional differences in quantitative pulmonary perfusion parameters in 10 volunteers with no evidence of interstitial lung disease by computed tomography, clinical, and laboratory data.

Materials and methods. 10 volunteers with no signs of interstitial lung disease were examined by three-dimensional ultrafast dynamic contrast-enhanced MR imaging using 3D T1-weighted images. The values of pulmonary blood flow (PBF), mean transit time (MTT), and pulmonary blood volume (PBV) for the targeted regions of interest were calculated based on the dynamic image series. For calculations, arterial input function (AIF) was used, as well as the time-intensity curves.

Results. The values of PBF, MTT, and PBV showed statistically significant differences between central and peripheral sections of lungs. Provided model can be implemented for quantitative assessment of regional pulmonary perfusion allows it to be used to determine the reliability of PBF, MTT and PBV values.

Conclusions. Three-dimensional ultrafast MRI sequence is a novel diagnostic modality allowing the assessment of regional quantitative pulmonary perfusion parameters in pulmonary tissue, regardless of physiological features of blood supply mechanisms in different lung regions.

Authors: Sergeev Artur M. , Pozdnyakov Alexander V. , Grechaniy Severin V. , Atamanova Elina E. , Pozdnyakova Olga F. , Shokin Oleg V. , Polishchuk Vladimir I.
Published: April 2022

Background. The delays in mental and speech development are caused by epilepsy, and a special place among the forms of which is focal temporal epilepsy. The study of biomarkers of the considered pathological condition using proton magnetic resonance spectroscopy as indicators amenable to objective assessment and measurement determines the practical relevance of this work.

Aim. The aim of the study was to determine the role and place of proton magnetic resonance spectroscopy in clinical practice in children with mental and speech retardation associated with temporal lobe epilepsy.

Materials and methods. 37 children aged 2 to 10 years were studied. Of these, 15 children with a diagnosis of mental and speech development delay, structural focal temporal epilepsy were included in the first comparison group. The second comparison group consisted of 12 children without CNS pathology undergoing 1H-MRI examination to exclude somatic diseases. The third comparison group consisted of 10 children with structural focal temporal epilepsy, without mental and speech development delay.

Discussion. Multivoxel proton magnetic resonance spectroscopy (method PRESS) was used to determine the concentration of neurometabolites in the brain tissues of patients. In patients with mental and speech development delay associated with temporal epilepsy, a decrease in the ratio of NAA/Cr concentrations (p 0.05) was revealed in the postcentral gyrus on the right, temporal lobe on the right and hippocampus and inner capsule on both sides, due to a decrease in the concentration of N-acetylaspartate; an increase in the ratio of Cho/Cr concentrations (p 0.05) in the prefrontal cortex, postcentral gyrus and inner capsule on both sides, due to an increase in the concentration of choline. Two patients also showed lipid peaks on the lesion side when compared with EEG data.

Conclusions. The revealed metabolic changes in patients with delayed mental and speech development associated with temporal lobe epilepsy may be useful as an additional method of differential diagnosis with other forms of mental and speech development delay.

Published: April 2022

Background. Мesocortical and nigrostriatal dopaminergic systems are highly sensitive to stressful events. One of the most adequate models of acute psychogenic stress in animals is the death of a partner upon presentation of a predator.

Aim. To study the content of dopamine (DA), serotonin and their metabolites: dioxyphenylacetic (DOPAC), homovanillic and 5-hydroxyindoleacetic (5-HIAA) acids in the prefrontal cortex, striatum, and ventral tegmental area in rats on days 3, 7, and 14 after the acute psychogenic stress of the death of a partner upon presentation of a predator.

Materials and methods. 28 male Wistar rats were studied. Acute single psychotraumatic situation was used. A group of rats was placed in a tiger python terrarium. One animal died as a result of its nutritional needs, the rest of the rats experienced the death of a partner. The content of monoamines in the brain structures was carried out by high performance liquid chromatography with electrochemical detection.

Results. Changes in the content of monoamines in the prefrontal cortex, striatum, and ventral tegmental area were found on the 7 and 14 days after the presentation of the predator. In the ventral tegmental area on the 7 day, there was an increase in the DOPAC/DA ratio and an increase in the serotonin metabolite 5-HIAA, which reflects an increase in the activity of dopamine and serotonin. In the prefrontal cortex on the 14 day, the DOPAС content and the DOPAС/DA index decreased. The 5-HIAA content in the prefrontal cortex and the 5-HIAA/5-HT value also significantly decreased.

Conclusions. Changes in the metabolism of monoamines after presentation of a predator develop gradually: increase of the dopamine and serotonin activity in the ventral tegmental area was noted on the 7 day after presentation of the predator, decrease in their activity in the striatum and prefrontal cortex only on the 14 day, reflecting the development of depressive states and post-traumatic stress disorder.

Psoriasis is a chronic immune-associated skin disease of a multifactorial nature with phenotypic diversity in the general population, as well as a large number of comorbid diseases in patients. The generalized pustular psoriasis, historically was considered one of the variants of the course of psoriasis. Today some authors classify it as a genetically different condition combined with a plaque psoriasis. The selected tactics of psoriasis therapy can become a trigger for the manifestation of a pustular form. Despite the availability of modern data on the immunopathogenesis of the disease, there are no standardized methods of treatment that can take into account the individual characteristics of patients, which is doubly important in pediatric practice, since the arsenal of drugs approved for use is limited. We demonstrate the clinical case of a patient with progressive plaque psoriasis, earlier getting systemic and topical corticosteroids for a long time. This therapy did not allowed to take the course of the disease under control, even more it caused appearance of complications. Our clinical example from practice allows us to focus on the problem of complications of classical therapy for psoriasis and the intricacies of prescribing both topical and systemic drugs. Systemic therapy requires the development of algorithms based on objective diagnostic criteria and the results of studies on the effectiveness and safety of modern drugs in pediatric practice.

Published: April 2022

Background and Aims: Acute gastrointestinal system hemorrhages are frequent, and anemia is frequently seen in patients with acute gastrointestinal system bleeding after hospital discharge. Studies intended for patient follow-ups after discharge and anemia treatment are limited, and this topic has no guidelines. This study aimed to evaluate anemia prevalence and clinical approach in patients with acute gastrointestinal system bleeding after hospital discharge and during 3 months of follow-up. Materials and Method: This study retrospectively evaluated 197 patients with acute gastrointestinal system bleeding who were treated at our hospital between January 2017 and May 2018. Upon discharge, anemia was accepted as hemoglobin levels of < 13 g/dL in men and 12 g/dL in women according to the World Health Organization criteria. Results: Of these patients, 129 underwent upper gastrointestinal endoscopy; 3 enteroscopy; 45 lower gastrointestinal endoscopy; 8 upper and lower gastrointestinal endoscopy; 2 upper, middle, and lower gastrointestinal endoscopies; and 10 did not undergo endoscopy. Additionally, 69 patients underwent therapeutic endoscopic treatments. The mean hospitalization duration was 10 ± 13.84 days, and 67% of patients had erythrocyte transfusion with a mean value of 3.5 ± 5.89 units during hospitalization. The mean hemoglobin rate was 9.85 ± 1.67 g/dL upon hospital discharge. Of the patients, 92.4% (female: 91.1%, male: 93.2%; upper gastrointestinal bleeding: 93.9%, middle gastrointestinal bleeding: 100%, lower gastrointestinal bleeding: 86.8%) had anemia upon hospital discharge and 9.7% underwent iron deficiency treatment. Of all 197 patients, 33% were evaluated 3 months after discharge from the hospital and 80% of these patients have ongoing anemia. Conclusions: Anemia frequency is high when patients with acute gastrointestinal system bleeding are discharged. Most patients are discharged without receiving a prescription for anemia. In the follow-up, control applications are inadequate and anemia persists in patients. A wider range of patient studies on the treatment application and adherence, as well as guidelines from the consensus body on this issue, is necessary.
Comparison of effectiveness of percutaneous nephrolithotomy versus retrograde intrarenal surgery
Authors: P. Srinivasrao , Shashidhar Mallidu
Published: April 2022

Background: Treatment of renal stones depends upon the stone size, location, symptoms and any other anatomical variation in the calyceal system of the kidney. Percutaneous nephrolithotomy (PCNL) is a highly effective operation with consistently high stone-free rates; it delivers good stone clearance with minimal problems and a lower retreatment rate, while it is associated with higher morbidity. Retrograde intrarenal surgery (RIRS) is a less invasive and practical therapeutic option with a short hospital stay, minimal morbidity, and a low complication rate. Objectives were to compare the effectiveness of PCNL and RIRS in the treatment of renal stones.Methods: 50 patients with renal stones with no comorbidities were divided into 2 groups. Group-1 was treated with PCNL, while group-2 underwent RIRS. The outcomes of both procedures were compared based on the operating time, duration of hospital stay and stone-free rate.Results: The mean duration of hospital stay was higher in the PCNL group (4.37±2.11 days) than the RIRS group (2.84±0.98 days). The stone free rate was more in the PCNL group (96%) as compared to the RIRS group (84%). The PCNL group (78±12.75 minutes) had a longer operative time than the RIRS group (70.59±10.09 minutes. Blood loss was more in the PCNL group.Conclusions: RIRS is an effective and safe alternative to PCNL in the treatment of renal stones. The choice of surgical approach between PCNL and RIRS should be based on the surgeon's experience and preference and the patient's financial means.

Impact of liquidity and profitability on share price: An analysis of Indian cement companies
Authors: Panigrahi Ashok , Vachhani Kushal , Sisodia Mohit
Published: April 2022

: All of the choices made in the workplace concerning cash, receivables, inventory, and payables influence how a corporation maintains its liquidity level. Liquidity plays a vital role in the successful functioning of every business. The important part in managing working capital is maintaining liquidity on a day-to-day basis to ensure the smooth running of the organisation and to meet its obligations. Hence, it is very important to keep a close eye on the liquidity position of the company as without it, the company cannot survive. But efforts to increase the profitability would tend to reduce firms' liquidity and too much attention on liquidity would tend to affect profitability. No doubt, every firm tries to maximise profitability by maintaining liquidity. But the question arises, is it the liquidity or profitability that helps in maximizing shareholder’s wealth by increasing the share price of Indian cement companies? Hence, the study is aimed to understand the impact of liquidity and profitability on the share price of Indian cement companies.

: To determine wheather investors in the cement sector should prefer companies those are liquid or profitable, we applied the t-test, correlation test, and the resultant p-value. It is found that, having a quicker cash conversion cycle (CCCy) increases the company's market value indicating that, higher the liquidity, more is the chances that the share price may go up.

: It is found that the profitability in cement companies isn't as high as the company's ability to pay its debts, i.e. liquidity. In other words, the liquidity of Indian cement companies are more and the profitability is less, and the market value of a firm rises in tandem with the growth in its liquidity. Moreover, when the market value grows, the CCC decreases, whereas the economic value added (EVA) increases.

: Prior studies reveal that the working capital requirements of Indian cement companies are much more as compared to other industries. Although low operational cash affects the daily operations of the business, excess working capital usage will harm the firm's profitability. Hence, the question, why do Indian cement businesses need so much of working capital? This study's purpose was to answer it. The findings of this research states that, companies believe that maintaining liquidity will increase their share price.

Relevance of trusteeship model in modern business world
Authors: Karunakaran N , Sajith Kumar B.
Published: April 2022

The background of Gandhian economy is very strong. Gandhi was fighting against extreme poverty, backwardness and socio-economic challenges as a part of the freedom movement. While the world has progressed manifold over the past century, the past few decades has forced to pursue that progress, mostly in terms of economic growth. The poster word for development, capitalism, has been busy in most countries. Trusteeship is a unique concept advocated by Gandhi to establish social and economic equality. It is a concept that has its origins in spirituality, in which a person voluntarily surrenders his surplus wealth, and entrusts it for the welfare of the poor section of the society.

The turbine consumption remains constant over time. The range of change in the reciprocating fuel compressor volumetric capacity is determined depending on the change in the intake gas temperature. The possibility of capacity regulation by changing the shaft speed and connecting an additional dead volume is considered. The available regulation depth is determined.
On the Friction Mechanisms and Assessment of Tribological Characteristics of Solid Lubricant Coatings of Various Application Methods
Authors: Khopin P.N.
Published: April 2022

The article analyzes the wear dynamics of solid lubricant coatings (SLC) of suspension, magnetron-high-frequency and diffusion methods of application. Calculated dependences are presented to assess the tribotechnical characteristics of the SLC. It was found that the service life of SLC based on MoS2 HF application in the considered ranges of surface temperature variations differs slightly from the that of SLC suspension application VNII NP 212. The wear of diffusion SLC M804 (Dimolit-4) in the steady-state friction mode is 34 µm. The wear rate of diffusion SLC М804 under vacuum conditions at a sliding speed of V = 0.2 m/s with the increase in contact pressure from 1 to 8 MPa increases by a factor of 2 and is on average 4.5 times higher than that of friction pairs with SLC VNII NP 212. Anti-friction characteristics of diffusion SLC in steady state friction modes at temperatures up to 600 °C were slightly higher than the similar characteristics for SLC with a binder. With an increase in heating temperatures to the limiting value of 800 °C, the friction coefficient of the diffusion SLC M801 and M810 (based on NbS2) decreases to the values of ffr = 0.03–0.04.

El arroz (Oryza sativa L.) está incluido en la dieta alimenticia diaria del 75% de la población mundial. En Costa Rica, el sector arrocero es un eje fundamental de atención, particularmente porque es el principal producto dentro de la canasta básica alimentaria. Estudiar la variabilidad morfo-agronómica de este cereal es un factor clave para planificar estrategias de mejoramiento genético. El objetivo de la presente investigación fue determinar cuáles son los caracteres morfo-agronómicos que tiene un mayor aporte a  la variabilidad genética en 54 líneas de arroz.  Las líneas evaluadas provienen de una colección del banco de germoplasma del CIAT de Colombia, estas fueron enviadas a Costa Rica a través de la Corporación Nacional Arrocera (CONARROZ). Se midieron siete variables morfológicas cuantitativas y cinco cualitativas. Para las cuantitativas, se calculó el coeficiente de variación y se realizó un Análisis de Componentes Principales (PCA), así como un Análisis de Agrupamiento. Con las cualitativas se realizó un Análisis de Correspondencia Múltiple (MCA).  Las variables cuantitativas más heterogéneas según los valores del coeficiente de variación fueron: toneladas por hectárea, tallos fértiles, y granos llenos por panícula. El PCA demostró que todas las variables, excepto la altura de la planta, aportaron a la varianza total, y el MCA sugiere que las variables cualitativas medidas en esta investigación, son discriminatorias para diferenciar genotipos. No se observó correlación entre las variables cuantitativas estudiadas. En el análisis de agrupamiento se obtuvo cuatro grupos de los cuales, uno de ellos abarcó la mayoría de los genotipos. Los genotipos de este último grupo se caracterizan por poseer altos valores para la variable granos llenos por panícula y valores medios y altos para el resto de las variables. Los resultados obtenidos son útiles para elegir las variables adecuadas para la selección. El análisis de conglomerados permitió establecer la relación filogenética entre las líneas para la planificación de futuros cruzamientos.

Impatiens walleriana is a plant of the Balsaminaceae family with high ornamental value. It presents very attractive flowers, which can be found in different shapes and colors, due to which, it is part of many gardens worldwide. Genetic improvement in this specie has usually been carried out by conventional methods, however, the advancement of technology has made possible the use of a large number of biotechnological and molecular tools. The objective of this review is to consolidate the bases for a genetic improvement program of I. walleriana. This review covers different aspects that are basic to incur in the genetic improvement of this species; these factors are floral morphology, pollination, karyotyping and studies of genetic variability. In addition, what is known to date about studies focused on genes involved in drought stress processes, tolerance to Plasmopara obducens and floral longevity is presented.
Mercado gastronómico en el Rímac : Recuperación del Mercado del Limoncillo + Obra nueva
Authors:   , Avendaño Quinta Karelia
Published: April 2022

El Mercado del Limoncillo es una edificación de valor histórico inaugurado en 1929 que está ubicado en el distrito del Rímac dentro de la zona perteneciente al Centro Histórico de Lima. Hoy en día este mercado se encuentra en un deficiente estado de conservación desde haber sufrido un recorte de sus estructuras en la década de los Sesenta sin ningún tipo de intervención de recuperación efectuada desde esa época. Así mismo, el distrito donde se encuentra ubicado el mercado está en la búsqueda de consolidar una identidad gastronómica por medio de ideas entabladas con la Asociación Peruana de Gastronomía (APEGA) para recuperar un gran porcentaje de viviendas y espacios con valor histórico en el distrito cuya intervención podría ayudar al objetivo que tiene esta asociación que consiste en convertir a la ciudad de Lima como capital gastronómica de Sudamérica al 2021. Es por estos motivos que el presente proyecto de tesis busca desarrollar en conjunto un planteamiento urbano inmediato a manera de conexiones urbanas y a su vez, la resolución de dos piezas arquitectónicas: una tipología nueva como un mercado gastronómico y la recuperación del mercado del Limoncillo por medio del cambio de su uso original. De esta forma, esta investigación se plantea como una nueva propuesta para la recuperación de un mercado histórico y al mismo tiempo de la identidad ciudadana Rimense, a través de la arquitectura y la gastronomía.
Vivienda social en Barrios Altos

Published: April 2022

Se desarrolló una tesis de Vivienda social en Barrios Altos. La vivienda social, es residencia de bajo presupuesto, económica en uso y mantenimiento destinada a familias de menores recursos. En este trabajo, se investigo la posibilidad de proponer un módulo de vivienda productiva o vivienda taller, que combine la vida con el trabajo en un mismo lugar. Se presentaron las motivaciones para investigar y proponer dicho proyecto en la capital, siendo el más importante solucionar el déficit habitacional existente y mejorar las condiciones de calidad de vida. Se presenta la investigación de proyectos referenciales nacionales e internacionales de la tipología (vivienda masiva), con los cuales se logra concluir con lineamientos formales, funcionales y tecnológicos necesarios para poder desarrollar el proyecto arquitectónico. Así mismo, se realizó un análisis sobre el carácter flexible en distintos proyectos arquitectónicos importantes, así como también en la teoría, ya que el proyecto enfatizará en esta característica para logar incluir vivienda y trabajo, para poder adaptarse a los distintos tipos de familias y su indudable carácter variable, y satisfacer necesidades actuales de adaptabilidad de uso. Además, se estudia sobre las condiciones del lugar y sobre las tipologías de vivienda existentes en la zona, en donde priman las viviendas de tipo quinta, callejones y casas patio, habitadas ahora por múltiples familias o combinando usos comerciales, en estas tres, resalta el sentido de la comunidad y pertenencia, cualidades que son importantes conservar a la hora de proponer el proyecto arquitectónico.
Mercado y Patio Gastronómico en Barranco
Authors:   , Arceo Lemoine Ariana
Published: April 2022

En el presente proyecto de tesis, se analizaron factores importantes para la ciudad de Lima de hoy en dia y el potencial de esta como capital para seguir creciendo culturalmente para sus ciudadanos y visitantes. Debido al auge gastronómico peruano, se propone un Mercado y Patio Gastronómico; tipología que se ha instaurado internacionalmente en Europa y Latinoamérica en el siglo XXI de manera exitosa, como reivindicación del mercado de abastos que fuera relegado por los “supermercados”. La propuesta se ubica en el distrito de Barranco, en un terreno donde funciona actualmente un mercado en malas condiciones de funcionamiento y sobre todo de seguridad y sanidad. El proyecto considera la población de vendedores actual y segrega según los tipos generando dos niveles de mercado y un patio de comidas; aprovechando el surgimiento del distrito como destino de turismo; siendo esta una oportunidad para la regeneración de ese sector. El proyecto se emplaza con una propuesta volumétrica adecuada en escala y proporción, que conserva la contención de las calles; típicas del distrito. Se propone una respuesta contemporánea en compromiso con su entorno.
Análisis de las variables comerciales que influyeron en las exportaciones de la partida arancelaria 20.05.99.1000, alcachofas preparadas o en conserva, durante los años 2008 - 2019, en el marco del TLC Perú - Estados Unidos

El comercio internacional presenta gran cantidad de ventajas, entre las que se encuentran, en primer lugar, la promoción de la diversificación de la oferta exportable. De manera significativa, la inserción de productos locales en nuevos mercados significa mayor crecimiento económico. Sin duda, la implementación del Tratado de Libre Comercio Perú - Estados Unidos en el 2009 consolidó el libre acceso para productos agrícolas. Para ello, el instrumento de política comercial como el Tratados de Libre Comercio presente, permitió al Perú el acceso comercial a uno de los mercados más grande del mundo. Se destaca la importancia del libre comercio y acceso para productos agrícolas, los cuales acercan al Perú a distintas cadenas de producción mundial y, de esta manera, se presenta “La gran oportunidad para el Agro”. Ello es certificado e impulsado por el sector agroempresarial e instituciones del sector público con sus mecanismos de legitimación de libre comercio que dan apoyo y acceso para implementar la operalización del mismo. El objetivo de la presente investigación es analizar los factores comerciales que influyeron en las exportaciones de la partida arancelaria 20.05.99.1000, alcachofas preparadas o en conserva, durante los años 2008 - 2019, en el marco del TLC Perú - Estados Unidos. Para ello se hace uso de un enfoque de investigación mixto. Por un lado, se hace uso del enfoque cualitativo, en el cual se analiza la influencia del Tratado de Libre Comercio Perú – Estados Unidos y los sistemas de certificación como factores que influyeron en el flujo de las exportaciones de las alcachofas en conserva. Por otro lado, se hace uso del enfoque cuantitativo causal y correlacional utilizando técnicas econométricas en base a series de tiempo con información mensual desde 2008 hasta el 2019. Los hallazgos de la presente investigación muestran que la variación en las exportaciones de alcachofas en conserva se debe principalmente a la firma del acuerdo comercial TLC Perú – Estados Unidos, los sistemas de certificación y determinantes del mercado internacional como la demanda del producto por parte de Estados Unidos y la producción nacional del mismo.
