La bioetica alla ricerca dei principi: la persona
Authors: Possenti Vittorio
Published: March 2022

Lo studio, premettendo che appare in questione il significato stesso dell'impresa etica nella vita umana, ritiene imprescindibile che l'uomo si interroghi sul significato dell"'esser morali", che l'Autore individua nella ricerca della luce del bene nell'ambito più generale dell'apertura all'essere. Da ciò si evince che le problematiche bioetiche basate su modelli di razionalità formali-astratte di tecniche logico-formali o sul "contrattualismo morale" conducono ad una bioetica povera di contenuto e di senso. Assume, perciò, valore emblematico e costituisce un crocevia imprescindibile per la soluzione di molti dei problemi delia bioetica, l'indagine meditante sulla persona nella sospensione della fretta. Le scienze biologiche non possono sapere alcunché della persona: ciò è di pertinenza del metodo filosofico, che è di tipo ontosofico. L'approccio che l'Autore ritiene consigliabile in bioetica al riguardo è, perciò, quello di operare uno "sguardo" antologico sulla realtà, la vita e l'essere uomini, dal quale sguardo emerga l'originalità e la specificità dell'essere persona: in una parola si tratta dell'approccio del "personalismo antologico''. Lo studio prosegue con l'analisi critica delle risposte filosofiche contemporanee alle seguenti due domande: "che cosa è persona?" e "chi è persona?" e si conclude con una sezione dedicata all'argomentazione in base a cui   possibile attribuire lo status di persona all'embrione.
Abstract No.: ABS2336: Ultra-sound-guided laryngeal air column width ratio as a predictor of post-extubation stridor in paediatric trauma patients: A prospective, observational study.
Authors: Chander Anjuman
Published: March 2022

Background and Aims:

Paediatric trauma patients need prolonged ventilation leading to post-extubation laryngeal oedema and stridor. Air-column width change reflects air leak and airflow around the endotracheal tube and vocal cords. Laryngeal air column width difference and ratio (LACWD and LACWR) are non-invasive methods for predicting the post-extubation stridor (PES).

Methods:

All children aged 1–14 years admitted to the trauma intensive care unit (TICU) for mechanical ventilation for >24 hours were included over 1 year. For intubated patients, if the size of the endotracheal tube was too large or too small, it was appropriate, whereas with an inappropriate size, the tube was changed. Cuff pressures were monitored and kept at or <20 cm of H2O. Dexamethasone was administered at 0.3 mg/kg/8 hours for 48 hours prior to planned extubation. LACW was measured on the day of receiving in TICU, immediately following intubation, prior to steroid therapy and before extubation. The Cuff leak test was used prior to the start of steroid therapy and before extubation.

Results:

A total of 50 patients were included, out of which 11 (22%) patients developed PES. Of the total number of patients, seven were intubated in TICU, whereas 43 patients were received intubation from outside. The positive predictive value cut-off of ultra-sound-guided LACWR to diagnose PES was <0.93 with a sensitivity of 90.91 and a specificity of 84.62.

Conclusion:

Ultra-sound-guided LACWD and LACWR are non-invasive methods of predicting PES in paediatric trauma patients.

Paraneoplastic Syndromes in Neuro-Ophthalmology
Authors: Hickman Simon J.
Published: March 2022

Paraneoplastic neurological syndromes (PNS) occur in about 1 in 300 cases of cancer. The usual mechanism is that an antigen on the cancer sets off an immune response that then cross-reacts with a nervous system antigen. The presentation is usually with a subacute progressive neurological disorder. The management of these conditions is usually of both the underlying tumor and immunomodulation to suppress the autoimmune response. There are a number of these conditions that can present to the Neuro-Ophthalmology clinic, either as a discrete condition affecting vision or eye movements or as part of a more widespread neurological disorder. This article will discuss these conditions, their management and prognosis.

Introduction:

In India, a national program for stroke (national programme for the control of cardiovascular diseases, diabetes, cancer, and stroke) and stroke management guidelines exist. Its successful implementation would need an organized system of stroke care in practice. However, many challenges exist including lack of awareness, prehospital notification systems, stroke ready hospitals, infrastructural weaknesses, and rehabilitation. We present here a protocol to investigate the feasibility and fidelity of implementing a uniform stroke care pathway in medical colleges of India.

Methods and Analysis:

This is a multicentric, prospective, multiphase, mixed-method, quasi-experimental implementation study intended to examine the changes in a select set of stroke care-related indicators over time within the sites exposed to the same implementation strategy. We shall conduct process evaluation of the implementation process as well as evaluate the effect of the implementation strategy using the interrupted time series design. During implementation phase, education and training about standard stroke care pathway will be provided to all stakeholders of implementing sites. Patient-level outcomes in the form of modified Rankin Scale score will be collected for all consecutive patients throughout the study. Process evaluation outcomes will be collected and reported in the form of various stroke care indicators. We will report level and trend changes in various indicators during the three study phases.

Discussion:

Acute stroke requires timely detection, management, and secondary prevention. Implementation of the uniform stroke care pathway is a unique opportunity to promote the requirements of homogenous stroke care in medical colleges of India.
Clinical profile of Kawasaki disease in children admitted at a tertiary care hospital of North India and their short-term follow-up
Authors: Banoo Nargis , Bashir Amber , Tariq Syed , Radhakrishnan Sitaraman , Abid Shaira
Published: March 2022

Aim:

The aim of this study was to evaluate presenting symptoms, clinical features, and laboratory tests for the diagnosis of Kawasaki disease (KD) in children and their short-term follow-up at a tertiary care hospital of North India from April 2017 to March 2020.

Materials and Methods:

A total of 31 children (23 boys and 8 girls) up to 10 years of age were included in this study. The diagnosis of KD was made as per the American Heart Association 2017 guidelines. Clinical features, laboratory parameters, and coronary involvement were compared between the complete and incomplete KD groups.

Results:

The incidence of complete versus incomplete KD was 19 (61.2%) versus 12 (38.7%) children, respectively. Change in extremities and oral mucosal changes were more encountered in the complete KD group as compared to the incomplete KD group (100% vs. 58.3%, P = 0.004, and 78.9% vs. 33.3%, P = 0.002, respectively). Coronary artery aneurysm was seen in 54% of the patients on echocardiography which was greater in the incomplete KD group (83.3%) as compared to the complete KD group (36.8%). The median time from the onset of symptoms to intravenous immunoglobulin infusion was <10 days in 84.2% of the patients with complete KD versus 41.7% with incomplete KD which was statistically significant. Fifty percent of the children with coronary ectasia and small aneurysm had normal coronaries at follow-up of 6 months.

Conclusion:

KD is probably underdiagnosed in most developing countries, like that of ours, and requires a high index of suspicion.
Exercise-induced electrocardiographic changes after treadmill exercise testing in healthy children
Authors: Malakan Rad Elaheh , Karimi Mohsen , Momtazmanesh Sara , Shabanian Reza , Saatchi Mohammad , Asbagh Parvin Akbari , Zeinaloo Ali Akbar
Published: March 2022

Background:

Treadmill exercise testing is a crucial diagnostic tool for evaluating congenital and acquired heart disease in the pediatric population. This study aimed to perform a comprehensive evaluation of exercise-induced electrocardiographic (ECG) changes in children. Although there are numerous studies on exercise testing in various cardiac pathologies, studies on exercise-induced ECG changes in normal children with coverage of all ECG parameters of atrial and ventricular depolarization and repolarization are very scant, if any.

Aims and Objectives:

This study aimed to investigate the exercise-induced ECG changes in healthy children and evaluate the effects of gender and four different formulas of heart rate correction of Bazett, Fridericia, Framingham and Hodges on ventricular repolarization parameters pre-and post-exercise.

Materials and Methods:

Between April 2019 and April 2020, all children with normal electrocardiogram, echocardiogram and exercise test, high-quality ECG tracings and consent for participation were enrolled in this prospective study. Twenty electrocardiographic parameters were measured and 25 indices were calculated. P-value < 0.05 was considered significant.

Results:

Seventy-four healthy children were studied. Amplitudes of P, S, and T waves increased significantly after the exercise. All durations, except P wave time to peak and T peak -T end /QT (Tp-e/QT) interval decreased significantly with exercise. Generally, the parameters of ventricular repolarization were not statistically significant between males and females. There were significant differences among the heart-rate corrected values of intervals of QTc, QoTc, JTc, J point to peak T and Tp-e/QTc by various formulas. There was no U wave either at pre-exercise or post-exercise. QT interval was shortened by 24.6 % ± 12.1 % with exercise. The ECG-derived estimated duration of mechanical systole and diastole decreased with exercise. The percentage of decrease in diastole was more than systole (43.79 %± 13.31% versus 33.74% ±15.79 %, respectively, P-value < 0.001).

Conclusion:

Diastolic time decreased more than systolic time with exercise and systolic time to diastolic time increased with exercise. Hodges' and Fridericia's formulas resulted in the longest and shortest QT and QoT, JT, and JTP, respectively. Thus, using a single value as the cut-off for long QT syndrome can lead to under or over-diagnosis. Nomograms incorporating data on age, heart rate, and heart rate correction formula are indispensable for accurate long QT diagnosis. Furthermore, gender differences in ventricular repolarization parameters are not generally present in 5 to 14-year-old healthy children. The lack of U wave in this study may implicate the need for more careful investigation in the presence of U wave in the treadmill exercise testing of healthy children.
Effect of the Coronavirus Disease 2019 Pandemic on Academics of Students Pursuing Masters of Occupational Therapy in Maharashtra State
Authors: Palsule Shilpshree Prashant , Khanna Henna Vijaypal
Published: March 2022

Background:

Masters in occupational therapy (OT) is a 3-year course offered by the Maharashtra University of Health Sciences. Maharashtra was one of the worst affected states by the pandemic in 2020 and thus its impact on academics might show greater ill effects. This study was conducted with an objective to understand the health-care students' perspective of how the coronavirus disease 2019 (COVID-19) pandemic affected their present academic and clinical reasoning skills and what they think about their future career in OT. The literature also suggests that health-care students experienced stress during the COVID-19 pandemic, but hardly any study was conducted on OT students. Hence, this study was conducted to identify the students' perspectives on perceived stress and academics due to the pandemic situation.

Objectives:

The objective of this study is to understand students' perspective on academics and clinical reasoning skills and future career implications, and their stress levels. To understand how teaching/academics can or has bettered/improved during such time.

Study Design:

An observational cross-sectional study design was chosen for the research.

Methods:

The study protocol was approved by the Institutional Ethics Committee. A validated semi-structured questionnaire was circulated through Google Forms to all 56 2nd-and 3rd-year students pursuing Master of OT in Maharashtra. The form consisted of 17 questions. Questions were based on how the pandemic affected their academics and the major academic and clinical concerns that the students faced during this period. Student's written and informed consent was attached to the online questionnaire. In addition to this, students were asked to respond to the Perceived Stress Scale to understand their stress levels.

Results:

The pandemic had an impact on clinical assignment in all 29 (100%) students. Not having enough opportunity to explore their clinical posting during the pandemic was experienced by all 29 (100%) students. The students found a gap in transforming theory into the clinical assignments. Having additional time for academics was stated by 14 (48.2%) students. Severe stress was perceived by 5 (17.2%) students and moderate stress was perceived by 24 (82.7%) students.

Conclusion:

The study concluded that all students had an effect on their clinical assignments, which may be due to reduced footfall of patients among the first wave of COVID-19 pandemic. Students claimed to have additional time for academics due to reduced patient load.
A Case of Accessory Anterior Hepatic Fissure
Authors: Patnaik Madhumita , Mohakud Sudipta , Gaikwad Manisha Rajanand , Ravi Praveen Kumar
Published: March 2022

The hepatic diaphragmatic surface is usually smooth and featureless. Although the existing literature mentions grooves or fissures on the diaphragmatic surface, there is no consensus regarding its causative factors. During routine dissection, the authors found a liver with a broad accessory fissure on the anterior surface of the anatomical right lobe. An enlarged hepatic area was observed on the left side of this accessory fissure. The undersurface of the right hemidiaphragm had a diaphragmatic band that extended into the hepatic fissure. The morphometry of the accessory fissure was studied. Retrospective magnetic resonance imaging showed that the middle hepatic vein was to the immediate right of the accessory fissure. Histological examination was done to confirm the presence of muscle tissue in the hypertrophied diaphragmatic band. As the need for surgeries and transplantations of the liver rises, there is a need to understand the hepatic macroscopic anatomy and its radiological correlation.

On Uniform K-Stability for Some Asymptotically log del Pezzo Surfaces
Authors: Fujita Kento
Published: March 2022

Motivated by the problem of the existence of Kähler–Einstein edge metrics, Cheltsov and Rubinstein conjectured the K-polystability of asymptotically log Fano varieties with small cone angles when the anti-log-canonical divisors are not big. Cheltsov, Rubinstein and Zhang proved it affirmatively in dimension 2 with irreducible boundaries except for the type (I.9B.

. Unfortunately, Fujita, Liu, Süß, Zhang and Zhuang recently showed the non-K-polystability for some members of type (I.9B.1) and for some members of type (I.9B.2). In this article we show that Cheltsov–Rubinstein’s problem is true for all of the remaining cases. More precisely, we explicitly compute the deltainvariant for asymptotically log del Pezzo surfaces of type (I.9B.

Face Recognition based Automatic Attendance Updating System
Authors: Raikar Amit , Tadkal Sharanabasappa
Published: March 2022

The current methods for taking attendance are inconvenient and time-consuming. Manual recording allows for easy manipulation of attendance records. A smart and validated attendance system is needed to tackle this problem. In smart attendance systems, face identification, fingerprints, Genetic material, retina, eye retina, gesture recognition, and other biometrics are often used. Humans can be identified by their faces, which have distinguishing traits. Face recognition is one of the most useful image processing applications, and it plays an important part in the technical world. The recognition of a human face is a hot topic for verification reasons, particularly in the context of school attendance. A face detection and recognition attendance system uses face biostatistics known for high monitoring and other computing technologies to identify students. The purpose of creating this system is to replace the traditional technique of documenting attendance by calling names and storing pen-and-paper records with a digital version. An innovative solution for a face recognition-based automatic attendance system is presented in this study. The findings are tabulated in an excel file, and students' attendance is processed depending on the date from the excel file, and relevant conclusions are drawn from this.
Tracking of objects in a multi-sensor fusion system for border surveillance
Authors: Patino Luis , Hubner Michael , Litzenberger Martin , Ferryman James
Published: March 2022

In this work, we present a Fusion and Tracking system developed within the EU project FOLDOUT aimed to facilitate border guards work by fusing separate sensor information and presenting automatic tracking of objects detected in the surveillance area. The focus of FOLDOUT is on through-foliage detection in the inner and outermost regions of the EU. Fusing several sensor signals increases the effectiveness of detection, particularly in forested and other areas hidden by foliage. We use weighted maps (also called Heatmaps) to combine multi-sensor information; tracking is performed on the resulting fused objects; a track is created or updated based on cost calculation of associating fused detections temporally. We compare tracking results from individual sensors and from fused objects from data collected in a simulated border that is representative of actual EU borders in Bulgaria. The results show how tracking is enhanced if performed on fused data rather than from individual sensor information.

The need for fast and precise information in combination with the huge technological developments concerning drone, information and sensor technologies, over the last few years, promoted the use of Unmanned Aerial Systems (UAS) in several domains ranging from agriculture to surveillance applications. The unique opportunity that UAVs and the accompanied payloads offer for acquisition of real time and precise data, make them a valuable asset especially for Law Enforcement Agencies that benefit from UAV’s capabilities, preventing or efficiently responding to several cases. Focusing on border external security, the continuous reports on cross border illegal activities apply constant pressure to Border Guard Authorities that aim to safeguard European borders, highlighting in this way, the need of new technologies and ways that will guarantee efficient border surveillance. In this framework, this paper analyses the methodological steps followed and the outcomes derived in the process of requirements identification up to the extraction of specifications, concerning an unmanned aerial system and its payload meaning the respective s censors for border surveillance that are capable of supporting border guard authorities on surveillance and search and rescue missions.
Some problems of rule-making of the federal executive bodies
Authors: Голодов П.В.
Published: March 2022

В статье рассматриваются отдельные вопросы качества и законности актов нормотворчества федеральных органов исполнительной власти, анализируется проблема обеспечения их надлежащего соотношения с законодательными актами. Автором приводится ряд конкретных примеров, подтверждающих существование данной проблемы. В числе основных недостатков отмечаются следующие: передача законом на подзаконный уровень решения вопросов, регламентация которых должна осуществляться на уровне законодательного акта; «вторжение» подзаконного нормотворчества в сферу законодательного регулирования, проявляющееся в создании так называемых норм первичного правового регулирования при отсутствии соответствующих законодательных норм или за пределами их фактического правового содержания. В целях решения рассматриваемой проблемы предлагается более широкое использование механизмов системы мониторинга правоприменения в Российской Федерации и системы общественной экспертизы нормативных правовых актов, а также цифровых технологий в нормотворческой работе федеральных органов исполнительной власти

The article examines certain issues of the quality and legality of acts of rule-making of federal executive bodies, analyzes the problem of ensuring their proper correlation with legislative acts. The author provides a number of specific examples confirming the existence of this problem. Among the main shortcomings are the following: the transfer by law to the subordinate level of the solution of issues which regulation should be carried out at the level of a legislative act; “intrusion” of bylaw rule-making into the sphere of legislative regulation, appeared in the creation of the so called norms of primary legal regulation in the absence of relevant legislative norms or beyond their actual legal content. In order to solve the problem under consideration, it is proposed to use more extensively the mechanisms of the law enforcement monitoring system in the Russian Federation and the system of public examination of regulatory legal acts as well as digital technologies in the rule-making work of federal executive bodies.

Epilepsy is a disease which causes neuronal damage and loss of consciousness in consequence of recurrent seizures. Nitric oxide as a neuromodulator in brain is a gas which can penetrate into cells. It has a significant role on physiological cases,pathology of many diseases such as inflammation and degenerative diseases. The purpose of this research is to search the activity of NO/cGMP pathway of valproic acid in an experimental acuteepileptic model which is induced with pentylenetetrazol in rats.18 adult male Wistar Albino rats were used in the study. The rats were randomly divided into 3 groups (n=6) as control group, pentylenetetrazol (PTZ+salin) 45 mg kg-1, valproic acid (PTZ+VPA) 150 mg kg-1. After 24 hours of PTZ application, all rats brain tissues were removed and then cortex and hippocampus were separated. While PTZ increased the hippocampus and cortex NO/cGMP levels compared to control (p <0.01), VPA decreased the hippocampusand cortex NO levels by comparison with PTZ (p <0.001). On the other hand, while VPA decreased cortex cGMP levels (p<0,05) it did not change cGMP levels in hippocampus (p> 0.05). This study has suggested that VPA can show antiepileptic activity via NO/cGMP pathway.

Las redes sociales son una parte importante en la vida de los jóvenes, en donde encontraron un medio para expresarse y compartir con familiares y amigos de forma fácil y divertida. Pero, los usos que los jóvenes universitarios les dan a estás redes no se detienen allí, ya que también las utilizan en el ámbito escolar. Sin embargo, cuando una institución educativa desea incluir de manera formal a estas redes sociales en sus procesos educativos, resulta necesario realizar una investigación para conocer a ciencia cierta cómo sus estudiantes las utilizan, para aprovechar así las ventajas que brindan y evitar el fenómeno creepy treehouse que ocurre cuando se intenta invadir el espacio social de un joven. El presente trabajo muestra los resultados de un grupo focal que explora las motivaciones y usos que los estudiantes de un campus universitario hacen de la red social Facebook. Los resultados muestran que los estudiantes aprovechan las funcionalidades del Facebook en el ámbito educativo, tales como: a)  la virtualidad para hacer trabajo colaborativo; b) la comunicación para asesorías con sus profesores, ponerse de acuerdo con sus compañeros en cuestiones de tareas y  dar avisos; c)  la facilidad para compartir y/o obtener recursos educativos subidos a la red por ellos mismos, compañeros  y profesores;  y d) la creación de grupos cerrados para trabajar exclusivamente con sus profesores, entre otros usos.

The article considers the problems of controlling power units of battery electric vehicles (BEV) when using in them specially configured automatic transmissions (AT) instead of single-reduction gear unit. The analysis of the BEV AT features in comparison with AT of hybrid electric vehicles of mass production is carried out. In comparison with AT gearboxes, BEV parameters are improved by most indicators. Among the new tasks is the coordinated control of the electric motor and AT clutches in the transients of shifting stages, and ultimately, the creation of an integrated control system for the BEV power unit. The methods of their solution by leading foreign companies are considered using examples with a typical 2-speed AT.

The structural-phase state of commercial titanium of grades ВТ1-00 (VT1-00) and ВТ1-0 (VT1-0) has been studied in the initial state and after various types of low-temperature ion nitriding. In the initial state, the VT1-00 and VT1-0 alloys have a single-phase α-Ti structure with a hexagonal close-packed crystal lattice. The hardness of titanium is 140–150 HV 10. It has been shown that ion-beam nitriding of VT1-00 alloy at low temperatures of 350 and 450 °С leads to the formation of thin (up to 5 μm) nitrogen-hardened layers with a hardness of 160–180 HV 0.05. As a result of ion implantation at temperatures of 500 and 550 °C, a nitrogen-modified layer with a microhardness of 190–220 HV 0.05 is formed in the surface layers of the VT1-00 titanium alloy, containing a solid solution of nitrogen in the α-Ti matrix phase. Nitrogen implantation of the VT1-00 alloy at a temperature of 620 °C leads to the formation of titanium nitrides TiN0.26, ε-Ti2N, η-Ti3N2-x in the surface layer of titanium alloy. The microhardness of VT1-00 titanium treated with nitrogen ions at 620 °C increases to 360 HV 0.05. In the case of ion-plasma nitriding (IPN) of VT1-0 titanium at 550 °C for 5 h, a nitrogen-modified layer up to 20 μm deep is recorded in its surface layer, containing isomorphic phases: α-Ti and titanium nitride TiN0.26. The microhardness of the VT1-0 titanium alloy subjected to IPN is 190 HV 0.01.

The article presents the analysis results of highly qualified personnel training in 2018–2020 in the field of mechanical engineering in the specialties falling within the competence of the Expert Council No. 18 of the Higher Attestation Commission of the Republic of Belarus, which showed that the most successful tasks in dissertation research are solved in the areas of developing technologies for creating: materials with gradient-oriented physical and mechanical characteristics; composite materials and protective coatings using nanoscale alloying and modifying materials; polymer materials and technologies, as well as the development of methods for assessing the durability of steel structures under their cyclic loads. However, despite the presence of a modern material and experimental base at the enterprises of the Republic of Belarus, among the applicants for academic degrees, there is a very small proportion of representatives of the real sector of the economy, training of which could make a scientific and practical contribution to machine science and provide significant support in solving the problems of ensuring the competitiveness and liquidity of products produced by successfully functioning major GDP generating domestic enterprises with production belonging mainly to the fourth technological paradigm. In fact, the main number of dissertations in these areas were executed by specialists of educational institutions and the National Academy of Sciences of Belarus, which have the appropriate field of activity and research equipment.

Se analiza el desplome de un ala como parte del diseño aeronáutico y, desde un enfoque aerodinámico, su origen y efectos en el funcionamiento de un avión. El desplome se muestra de manera tangible mediante pruebas en túnel de viento con modelos de alas sometidas a grandes ángulos de ataque. Para las pruebas se construyeron modelos de alas, el mecanismo de medición de oscilaciones y el módulo de pruebas. Se determinaron experimentalmente la frecuencia de oscilación del cabeceo del modelo y la visualización del flujo desprendido sobre el mismo. Los resultados explican la fluctuación de las reacciones aerodinámicas durante la pérdida de sustentación. Estos resultados y la experiencia obtenida durante el desarrollo del trabajo enriquecen el acervo académico y de investigación ya acumulado sobre el desplome de alas con números de Strouhal del orden de 0.02 y de Reynolds del orden de 300000, apropiados para aviones pequeños como los UAV´s.

The purpose of this study was to investigate the influence of institutional factors on access to County Vocational Education and Training institutions in Makueni County, Kenya. The study was informed by the existence of a large number of youths in the County who have not enrolled in CVETIs hence leading to high population of idle youths with low or no relevant employable skills which contributes to increased dependency ratio, high unemployment rates, engagement in drug and substance abuse and other social-evils. The study sought to investigate whether, the career guidance services influence access to County Vocational Education and Training Institutions in Makueni County, Kenya. The study was guided by Human Capital Theory (HCT). The study employed descriptive research design. The study targeted 28 registered Public Vocational institutions in Makueni County. The study used stratified simple random sampling and purposive sampling techniques to obtain a random sample of 21 managers, 87 instructors and 316 trainees drawn from 21 randomly selected Vocational institutions. Questionnaires, interview schedule and an observation check list were used to collect data. Data were processed and analyzed qualitatively and quantitatively. Descriptive statistics that is, frequency distributions, percentages, means and standard deviations were generated and used in describing and discussing the research findings. Statistical tests were done using a T-test and one-way analysis of variance (ANOVA) at 95% Confidence Interval of the difference (α=0.05). An independent sample t-test was conducted to compare mean difference between if career guidance influence access to county vocational education as well as training institutions and professional qualification of the managers. The findings of the study revealed that, Most of the vocational institutions have no organized and functional career guidance departments to provide in-depth information on individual courses, inadequate career guidance services has an influence on access to CVETIs and trainees’ career progression. Based on this findings the study recommended that the institutions should establish functional career guidance departments to provide in-depth information on individual courses and career guidance on vocational education to be introduced at the lower level of basic education.
