Authors: Fadzil* Ahmad , Listyanti Nyosisca 
Published: September 2024

The actions of a company constantly connect and bind the connection between different organizations via communication. If the firm does not have excellent communication, it can lead to conflict and impair employee productivity, which might hinder the establishment of the company's own objectives. For instance, at PT Bina Bestari Semarang—a company that specializes in coordinating labor services—a dispute develops when executives and workers fail to communicate, which in turn reduces staff productivity. This research will look at how PT. Bina Bestari's leadership has been able to boost staff performance and productivity via their communication strategies. This study employs a qualitative methodology based on a case study design, with data collected via in-depth interviews, participant observation, and written records. This study's findings suggest that leadership is doing a good job of carrying out their responsibilities and that the vertical communication model between superiors and subordinates may work as intended. All parties involved in the dispute at PT Bina Bestari division have acknowledged that things started to look better when it came to communication between workers and management, which in turn led to a rise in output

The aging process experienced by the elderly causes the elderly vulnerable experiencing changes in psychological status that can affect their blood pressure. This study aims to determine the correlation between psychological status and blood pressure in the elderly at Banjar Kajeng, Denpasar City. This research is a quantitative research that used a cross sectional method which was carried out on for one week in March 2023. The sample selection in this study used purposive sampling (n=45). Data were collected using The Depression Anxiety Stress Scales 21 (DASS-21) questionnaire and a digital sphygmomanometer. The results obtained through the spearman rank test shows that there is a correlation between psychological status and blood pressure in the elderly at Banjar Kajeng Denpasar City with p=0,004, r=0,419 for the correlation between psychological status and systolic blood pressure and p=0,044, r=0,302 for correlation between psychological status and diastolic blood pressure. The contribution of psychological status to the increase in systolic blood pressure is 17,56%, while the contribution of psychological status to the increase in diastolic blood pressure is 9,12%. Psychological status is related to blood pressure, which means that if the psychological status value is high, then blood pressure will also be high. Implementation of special activities for the elderly, such as posyandu, exercise, and health education can be carried out to help maintain the stability of the psychological status and blood pressure of the elderly.

Hypertension is a disease of the heart and blood vessels characterized by increased blood pressure. Non-pharmacological efforts can be done by soaking the feet in warm water which can have a relaxing effect and dilate blood vessels. The aim of this study was to compare soaking feet in warm water mixed with lemongrass and salt for 10 and 15 minutes in hypertensive elderly at the Cempaka Putih Community Health Center. The research method uses an experimental two group pretest posttest design. Purposive sampling with inclusion and exclusion criteria. Each group consisted of 19 respondents, tested using Mann Whitney. The results showed that the systolic pre-mean for the 10 minute group was 147,37 mmHg, and the diastolic average was 92,37 mmHg. The experimental group's 15-minute pre-systolic mean was 150,53 mmHg, with diastolic 88,42 mmHg. Post mean systolic results for the 10 minute group were 129,47 mmHg with diastolic 83,16 mmHg. In the experimental group 15 minutes post the mean systolic was 123,68 mmHg and diastolic 81,58 mmHg. The Mann Whitney test shows that there is a difference in the mean reduction in systolic and diastolic blood pressure with a p-value of 0,049 in systolic and 0,000 in diastolic. The mean rank value shows a decrease in pre and post systolic at 10 minutes of 22,87 while at 15 minutes it is 16,13. The results of the decrease in the mean diastole of the 15 minute group (11,23 mmHg) were smaller than those of 10 minutes (17,66 mmHg). It can be seen that the mean systole and diastole in the 15 minute group is smaller than 10 minutes, so it can be concluded that soaking the feet in warm water mixed with lemongrass and salt is more effective for 15 minutes in reducing both systolic and diastolic blood pressure in hypertensive elderly at the Cempaka Putih Community Health Center.

Authors: Chike, Enyinda  , Ohanuna Chukwudi  
Published: September 2024

This study was carried out to assess the air quality implications of gas flaring in selected communities prone to oil and gas activities in Rivers State. The study made use of both primary and secondary data. Primary data were collected from field measurements of nitrogen dioxide (NO2), sulphur dioxide (SO2), hydrogen sulphide (H2S), carbon monoxide (CO), suspended particulate matter (SPM), noise levels, wind speed, relative humidity and temperature while secondary data were retrieved from online journals and published articles. The results revealed that the mean concentration of NO2, SO2, H2S and CO ranged from 0.03ppm-0.4ppm, 0.01ppm-0.59ppm, 0.01ppm-0.3ppm and 0.83ppm-11.12ppm respectively. SPM concentration ranged from 2.06mg/m3-9.76mg/m3 while noise levels ranged from 67.3dBA-71.2dBA. Analysis of meteorological variables revealed that wind speed, relative humidity and temperature ranged from 0.48m/s - l.38m/s, 62.4% - 69.7% and 32.60C - 38.00C, respectively. ANOVA analysis on the variation in air quality parameters and noise levels between the flare site and control site showed a value of 0.00., implying a statistically significant variation in air quality parameters and noise levels between the flare site and control site. Pearson Product Moment Correlation computed for hypothesis 2 revealed that there is no statistically significant relationship between micro-climatic parameters (Temperature, relative humidity, wind speed) and the concentration levels of carbon monoxide (CO), sulphur dioxide (SO2), and nitrogen oxide (NO2).

Authors: Dr. Kaanaeli Gabriel NNko  
Published: September 2024

Engaging employees in the strategic planning process is essential for the successful implementation of strategic objectives in the public sector globally and in Africa in particular. A number of studies have been carried out to rationalise the importance of employees' engagement in the strategic planning process. Nevertheless, there was a scarcity of studies that investigated the strategies used by public organisations to ensure the active participation of employees in the strategic planning process. The current study filled the gap by examining strategies employed by public organisations to ensure the engagement and Participation of employees in the Strategic Planning Among Public Sectors in Tanzania. The study was carried out in Dar-es-Salaam region, Tanzania, involving 20 participants selected through purposive and convenient sampling techniques from public sectors. Interviews were used to collect field data, which were analysed thematically, and the themes emerged. All research ethics principles were observed during data collection, including seeking participation consent from participants and ensuring participants' information is kept confidential. From the analysis, the findings indicated a number of strategies employed by public sectors in Tanzania to ensure the engagement and participation of employees in the strategic planning process. They identified strategies that include participatory workshops, task forces and committees, and training and development. Others are feedback mechanisms and clear communication channels, performance management alignment and incentives, and continuous improvements. The study findings conclude that engagement and participation of employees in the strategic planning process is essential and that the identified strategies used by public sectors in Tanzania create a more inclusive and participatory strategic planning process, leading to better alignment, engagement, and successful implementation of strategic initiatives.

Role of scheduled repeat CT scan in traumatic brain injuries: A prospective observational study
Authors: Beedkar Saurabh , Prasad G. Lakshmi , Menon Girish 
Published: September 2024

Background:
Scheduled CT scan is a routine practice at many centers after traumatic brain injury (TBI), but it has been questioned by few authors. The majority of the studies are reported in mild TBI; however, no specific data exist for the same in moderate and severe TBI.

Methods:
This was a single-center and 1-year prospective study. All cases with TBI who underwent scheduled repeat scans were included in the study. Patients who underwent emergency surgery after first computed tomography (CT) and those who expired before repeat CT were excluded from the study. Data included demographics, Glasgow coma scale (GCS) score, initial head CT findings, findings of repeat CT, and the need for any intervention (medical/surgical).

Results:
A total of 231 cases were analyzed. The mean time interval for the repeat CT was 7.8 h. One hundred and seventy-one patients underwent scheduled repeat CT (Group 1), 53 patients with GCS >13 were discharged from emergency before the repeat scan (Group 2), and seven cases underwent repeat CT before the scheduled time in view of clinical deterioration (Group 3). The mean age and gender did not vary significantly between the three groups. Mixed lesions predominated in all; however, the proportion significantly differed between groups. In Group 1, two patients required surgery; in Group 3, all patients required a significant change in treatment, whereas none deteriorated or required a repeat scan in Group 2.

Conclusion:
In our study, the yield of routine repeat CT scans requiring surgery was 3.5%. Based on the results of our study and the observations from previous studies, we have proposed a few general working statements regarding indications for repeat CT scans in TBI.

Published: September 2024

Рассматривается подход к созданию математических моделей протяженных объектов, с использованием которых могут решаться такие задачи, как математическое моделирование слежения за той или иной целью с использованием оптико-электронной системы, в том числе лазерного локатора, когда парциальный канал приемного устройства оказывается значительно меньше изображения объекта слежения в фокальной плоскости, а также моделирование земной поверхности, которое, например, требуется при рассмотрении навигации по ее рельефу. Рассмотренные в статье математические модели являются важной составляющей более общих моделей излучения объектов, описание которых далеко выходит за рамки тематики данной статьи.
We consider an approach to the creation of mathematical models of extended objects, which can be used to solve such problems, as mathematical modeling of tracking for a particular purpose using an optoelectronic system, including a laser locator, when the partial channel of the receiving device is much smaller than the image of the tracking object in the focal plane, as well as modeling of the earth’s surface, which, for example, is required when considering the navigation along its relief. The mathematical models considered in the article are an important component of the more general models of radiation of objects, the description of which is far beyond the scope of this article.

Представлены результаты сравнительного изучения влияния выбросов автотранспорта на весь комплекс параметров двух разных придорожных лесных фитоценозов (дубняка и березняка), находящихся при одинаковой нагрузке фитотоксичных загрязнителей атмосферного воздуха. Показано, что степень дефолиации является одним из основных показателей оценки состояния лесов. Широколиственный дубовый лес оказался более чувствительным к токсичным выбросам автотранспорта по сравнению с мелколиственным берёзовым лесом. Выявлены и другие диагностические признаки состояния изученных экосистем. Увеличение числа видов макромицетов прослеживается по мере удаления от шоссе как в березовом, так и в дубовом лесу. При изучении состояния покрова эпифитных зелёных мхов на основаниях стволов деревьев на разных расстояниях от трассы наиболее показательной оказалась мощность мохового покрова, выявлена строгая зависимость её величины от расстояния от дороги и, соответственно, от величины нагрузки выбросов автотранспорта. Отсутствие лишайников не всегда может служить сигналом высокой степени загрязнения воздуха – так, в дубняке они полностью отсутствовали даже на большом расстоянии от дороги (дальше 130 м), а в березняке Parmelia sulcata Tayl. была обнаружена уже в 60 м от трассы.
The results of a comparative study of the impact of vehicle emissions on the entire complex of parameters of two different roadside forest phytocenoses (oak and birch), which are under the same load of phytotoxic pollutants of atmospheric air, are presented. It is shown that the degree of defoliation is one of the main indicators for assessing the state of forests. Broadleaved oak forest proved to be more sensitive to toxic emissions of vehicles, in comparison with small-leaved birch forest. Other diagnostic features of the condition of the studied ecosystems were also revealed. The increase in the number of species of macromycetes can be traced as far as the distance from the road in both birch and oak forests. When studying the state of the cover of epiphytic green mosses on the bases of tree trunks at different distances from the track, the thickness of the moss cover proved to be the most indicative, its dependence on the distance from the road and, correspondingly, on the magnitude of the load of motor transport emissions was revealed. The absence of lichens can not always serve as a signal for a high degree of air pollution – so, in the oak forest, they were completely absent even at a great distance from the road (further 130 m), and in the birch forest Parmelia sulcata Tayl. was found already 60 m from the road.
