Pages: 1 - 13
Abstract: This study investigates the effect of integrated reporting on the financial performance of quoted finance companies in Nigeria from 2014 to 2020. The study used a sample size of 28 finance companies quoted on the floor of the Nigerian Stock Exchange, now called exchange group, by way of the purposive sampling method. The researcher used an ex-post facto research design. The dependent variable was measured by earnings per share. The independent variable was measured by integrated reporting. The study employed a secondary source of data obtained from the finance firms' annual reports and the Nigerian exchange group website. The results from the multiple regression analysis proved that integrated reporting has a positive relationship with the financial performance of quoted finance companies in Nigeria. Based on the findings and the study's conclusion, the study recommends that The Financial Reporting Council of Nigeria (FRCN), the country's standard-setter, make integrated reporting mandatory, as it is in South Africa.

- Decision Making Strategy In Regional Based New And Renewable Energy
Governance Planning As A Supporter Of State Defense (East Nusa Tenggara
Case Study)
Authors: Syaiful Hidayat ; Purnomo Yusgiantoro , Suyono Thamrin , Rudy Laksmono Widayatno
Pages: 14 - 24
Abstract: The important role of energy in the country's economy causes the need for energy security, such as availability and ease of
access. Limited fossil energy sources require diversification from the use of new and renewable energy sources (EBT).
Therefore, the important role of energy in the economy is directly linked to the element of national security. The national
defense sector, which has the duty and responsibility of maintaining regional sovereignty, requires energy to support
national defense efforts. The reciprocal relationship between defense and energy shows the urgency of energy. In the area
of Indonesia that is in energy use, when viewed from the level of electrification ratio, the province of East Nusa Tenggara
(NTT) is the region with the lowest level. Energy supply support to support defense in the NTT region must be planned
effectively, efficiently and sustainably. NTT has the potential for wind energy worth 10,130,000 MW and the potential for
solar energy worth 9,930,000 MW. The potential needs to be managed through the right policy planning strategy. The
formulation of targets, alternative engineering and evaluation of alternatives are needed in strategic planning so that the
assessment of alternatives based on assumptions can fully identify the policy needs of the NTT region.

- Energy Management Strategy For State Defense Toward The Energy Crisis
Authors: Syaiful Hidayat ; Purnomo Yusgiantoro , Suyono Thamrin , Rudy Laksmono Widayatno
Pages: 25 - 35
Abstract: Energy needs to support activities make energy an influential factor for everyday life. The guarantee of the
availability of energy supply which has decreased requires diversification. Energy for defense requires a
management planning strategy by supporting government programs, namely the energy mix using new and
renewable energy (EBT). Through this research, it is hoped that an effective and efficient energy management
strategy for national defense can be obtained in the face of the energy crisis experienced by Indonesia. The
method used is by conducting literature studies through policies related to defense and energy and studying
existing phenomena. The results showed that the need for electricity to support military base operations can
use power plants with renewable energy sources. Regional arrangement based on the energy potential that
is owned can be used as a strategic area for the formation of a defense area plan. The synergy between the
targets of the National / Regional Energy General Plan (RUEN / D) and the Regional Defense Plan (RWP) can
create infrastructure that can support the management and utilization of energy for military bases. Strategies
that can be carried out are to carry out an inventory of the potential for new and renewable energy in various
regions, do more in-depth research, make plans in more detail and finally determine energy generators that
are suitable for availability and needs.

- Geospatial Intelligence For The Selection Of Locations For The New
Indonesian Presidential Palace
Authors: Sa’dianoor ; Syamsul Maarif , Sobar Sutisna Edy Saptono
Pages: 36 - 47
Abstract: Geospatial Intelligence (GEOINT) has expanded to various fields of life. By combining with the science
of geography to produce defense geography. This study aims to see the ability of GEOINT in assisting the
selection of the location of the presidential palace, which is planned to be moved from Jakarta to East
Kalimantan. Using photogrammetric data can produce an overview of the planned location of the capital as a
basis for competent respondents to make choices. Of the eight respondents, all of whom live or work around
the planned location of the capital city, they got the best alternative based on GEOINT data. Respondents
chose alternative 1 because it had the highest score from the aspect of physical geography and socio-cultural
geography. From the interviews, most of the respondents wanted a location that was safe from flooding and
far from residential areas and there was no relocation of residents. The conclusion is that GEOINT can
summarize the condition of the planned location of the new state capital from a physical and socio-cultural
perspective. GEOINT is not only useful for military purposes but also for non-military interests.

Pages: 82 - 98
Abstract: Using the quality by design concept (QbD) and a DoE methodology to identify the design space for a technique of Related impurities method for Clofarabine API, Clofarabine parenteral dosage form, and reconstitution studies using 0.9 percent sodium chloride.
Using design expert software, DoE was used to do a simultaneous multivariant approach for pH, buffer strength in the mobile phase, and flow rate. Trials were done in a two-level fractional factorial design (2 4-1 + 4 canter points = 12 experiments) to establish design space. Method development experiments were performed by using a composite degradation sample with spiked known impurities. Degradation unknown and known impurity pairs were studied statistically to identify the chromatographic parameters essential for their resolution. Various data tables, such as analysis of variance and Pareto charts, were used to assess conclusions made during this process. The 'design space' of the method's chromatographic factor range was shown in the plot of desirability. The procedure is exact, specific, accurate, and reliable all at once. This method is found suitable for the quantification of impurities in Clofarabine API, Clofarabine parenteral dosage form, and reconstitution studies.

Pages: 114 - 122
Abstract: The purpose of this study was to examine the effects of complex exercise for 12 weeks on the bone
mass content, diabetes risk factors(HDL-C, LDL-C, HbA1c, TC, TG), BDNFs, which are brain derived neurotrophic
factors, inflammation-related factors(IL-6, TNF-α) of type 2 diabetic patients. The subjects of this study were 50-
70 years old female type 2 diabetic patients residing in Busan selected through simple random sampling and
assigned to an exercise group of 10 subjects and a control group of 10 subjects. A complex exercise program was
administered to 20 type 2 diabetic patients (10 in an exercise group, 10 in a control group) for 60 minutes per
time, three times per week for 12 weeks and differences in the amounts of changes were analyzed. As for
changes in bone mass content (BMC), whereas the exercise group did not show any significant change, the
control group showed significant decreases and the difference in mean values between the two groups was
significant(p<.01). Among diabetes risk factors, HbA1c was shown to be statistically different between the two
groups after the execution of the complex exercise program(p<.05). HDL-C was shown to be statistically different
between the two groups after the execution of the complex exercise program (p<.01), and changed significantly
in the complex exercise group but not in the control group(p<.01). Changes in BDNF were analyzed and the
results indicated significant intergroup differences (p<.01). The results of analysis of changes in IL-6 also showed
significant intergroup differences (p<.01). Through this study, it could be seen that the 12-week complex exercise
program is effective for the prevention and treatment of diabetes and diabetic complications because the
program improved the factors such as the bone mass content, HDL-C, HbA1c, BDNF, IL-6 of type 2 diabetic
patients.

Pages: 123 - 134
Abstract: The purpose of the current study was to investigate health-related and skill-related such as strength endurance,
flexibility, and agility, speed physical fitness of elite youth under-17 Ethiopian football players across four
different positions considered as fullback, center back, midfield, and striker. The current study employed a crosssectional survey design with a purposive sampling technique to obtain the required data. Thus, 75 (62.5%)
volunteer elite youth under-17 players were selected from five elite youth under-17 football clubs. There were
statistically significant differences among positions of play in agility, F (3, 71) = 2.92, P < .05; flexibility, F (3, 71)
= 2.65, P < .05; and speed, F (3, 71) = 2.89, P < .05. However, there was no statistically significant difference in
strength endurance across four different positions of players. We suggest that Ethiopian elite youth U-17
football coaches should test and record fitness profile of players vis-à-vis their position of play and identify
players’ individual level of fitness in comparison to the demand of contemporary football game in general and
their positions of play in particular.

- Effect Of Soil Compaction In Central And Southern Iraq On Growth And
Productivity Of Wheat And Rice Crops
Authors: Asaad RAJ Al-Mhannawi; Hussein GA Al-Kellabi
Pages: 135 - 140
Abstract: A field study was carried out to reveal the effect of compaction of irrigated soils resulting from the movement of heavy machinery adopted in soil and crop management processes in central and southern Iraq on some physical, water and engineering properties of soil. The effect of compaction of heavy and light soils in the fields of cereal crops "wheat and rice" was studied. The study was conducted on eight sites in four stations of different textures, two sites in each station. The four sites are Al-Fajr district, Dhi Qar governorate (mixed texture soil), sand dunes station located on the FAO project between Dhi Qar and Al-Qadisiyah (mixed sandy soil), rice research station in Al-Mashkhab area/Najaf governorate (clay mixed soil), and Al-Qadisiyah-Hor Salib region (Alluvial clay soil). The study focused on comparing sites with compacted soils with sites with non-compacted soils in terms of some of the growth and yield measures (plant length, horizontal root length, deep root length, and dry weight of total yield) of wheat and rice yields affected by soil compaction. The results showed the clear effect of soil compaction on the vegetative growth of wheat and rice crops. In general, a significant decrease in growth indicators and yield was observed in the frequently cultivated compacted soil sites (C1) compared to the neighboring newly planted (un-compacted) sites (C0). This effect was negatively reflected on plant height, root system and yield, and led to a decrease in total yield in Qadisiyah and Mashkhab stations, which are characterized by clay soil, and Al-Fajr station with mixed soil. In general, the compaction operations affected the physical properties of the soil and led to a clear imbalance in the growth systems and yield indicators. This is in addition to the risk of soil detoriration over time and an increase in compaction due to pressure and repeated cultivation.

Bruchidae)
Authors: Jumaʹa T. Muhammad ; Ibrahim A. Hassan Basem A. Taha
Pages: 148 - 159
Abstract: Laboratory study was conducted at Plant Protection Department/ College of Agriculture and Forestry/ University of
Mosul, Iraq, during 2021, to investigate the bioactivity of powders from Fenugreek, Trigonella foenum-graecum L.
(seed) (Fabaceae), Oleander, Nerium oleander L. (leave) (Apocynaceae) and Coriander, Coriandrum sativum L. (seed)
(Apiaceae) against the reproduction and damage of Callosobruchus maculatus F. (Coleoptera: Bruchidae) on cowpea
seed (Vigna unguiculata (L.) walp), based on the rate of egg-laying performance, the emergence of the adult, the
percentage of decrease in the first generation, seed damage, weight loss of cowpea seed, weevil perforation index
(WPI)% and the percentage of germination of seeds infected by this insect. The powders were incorporated at rates 0.0
(control), 0.2, 0.5, 0.7, 1.0 g/10 g cowpea seeds. Results of this studies revealed that C. sativum at concentration
1.0g/10g seed had significantly negative effects on C. maculatus for all parameters measured. T. foenum-graecum and
N. oleander also showed significant effects but with less effect. The results indicate that these botanical powders have
the potential to protect cowpea seeds from cowpea weevils damage compared to when the seeds stored unprotected.
They should, therefore, be included in pest management strategies for C. maculatus in grains stored on-farm in rural
tropical and subtropical regions.

Pages: 160 - 166
Abstract: The study aimed to investigate the effect of microwave radiation at different exposure periods (0, 2,
4, 6, 8, or 10 min) on the chemical composition and physical and chemical properties of olive oil. The
effect of microwave radiation on olive oil was also tested after adding some antioxidants including
vitamin E, BHT and BHA at concentrations of 300, 400, 500) ppm, respectively. The measurements
included calculating the pH, peroxide, viscosity, density, refractive index and absorbance (UV at
wavelengths of 232 and 270 nm). The results showed that exposing olive oil to microwave rays
increased, although not significant, in acidity number, refractive index and density. On the other
hand, the values varied between significant and insignificant with respect to smoking point and
viscosity until the end of the exposure period, while the absorbance increased at wavelength 232 and
271 nm with increasing exposure period.

- Ready To Bake Multigrain Cookies
Authors: Khushboo Singhal ; Amit Pratap Singh , Ashish Khare , Apoorva Behari Lal , Anurag Singh
Pages: 189 - 200
Abstract: Traditional cookies are ready to eat and the most palatable snack product widely available in the market. These cookies
are low in protein and dietary fibres. Also, the preparation of fresh cookies at home is a tedious and time-consuming process.
Therefore, an attempt was made to prepare ready-to-bake multigrain cookies with a high protein and fibre content. These
ready-to-bake cookies will be available in the market in the form of frozen unbaked cookies that only have to be baked at home
so that the consumers will get freshly baked cookies with increased nutritional value. In this study, barley flour (BF) and cornflour
(CF) were incorporated with refined wheat flour (RWF) in various proportions. The incorporation of barley increases the protein,
fibre and adds beta-glucan to cookies which is very beneficial for health, while corn flour improves the taste and texture of the
multigrain cookies. Therefore, five different formulations for ready-to-bake cookies were prepared, i.e. S1 (RWF: BF: CF :: 70:
20: 10), S2 (RWF: BF: CF:: 60: 30: 10), S3 (RWF: BF: CF:: 50: 40: 10), S4 (RWF: BF: CF:: 40: 35: 25), and S5 (RWF: BF: CF:: 30: 30:
40). Based on the physicochemical and sensory evaluation of baked cookies, Sample S4 was found the most acceptable. The
unbaked cookies of Sample S4 were then stored at freezing temperature -18°C in the deep freezer. The sensory characteristics
of the frozen stored cookies (after baking) were studied at an interval of 15 days for about three months of frozen storage. No
significant changes have appeared in the quality of ready-to-bake cookies during frozen storage. Thus, this study's outcome will
help in development of healthy multigrain cookies, which can be baked at home in a few minutes.

- Large Scale Simulation Of Cyanovirin Production From Conventional And
Biotechnological Techniques
Authors: Martín Torres ; Jose Carvajal ; German Gelves
Pages: 201 - 211
Abstract: This paper's primary purpose is to determine the best cyanovirin-N n large-scale technique for production
based on its pre-feasibility reached using the traditional method (applying recombinant soybean) and the
biotechnological method (employing Nostoc ellipsosporum cultures in bioreactors). Cyanovirin-N is a lectin capable
of inhibiting HIV type 1 and 2 infections. Hence the importance of optimizing production and improving costeffectiveness for its use as immediate treatment in HIV patients is crucial for further researches. In various studies,
it is confirmed that the problem lies in the low production of cyanovirin at the level of Nostoc ellipsosporum.
However, this method is essential to find a solution since the operating conditions can be controlled and not
dependent on environmental factors as in traditional processes. The results obtained using SuperPro Designer®
software indicate that the soybean produces a greater quantity of crystallized cyanovirin-N (744.48kg/h), but it is
not profitable due to the annual operating cost (USD) $ 458,892,000. The latter is due to its comparison to the results
using Nostoc ellipsosporum. This latter reveals lower cyanovirin-N crystals (0.36kg/h). However, the annual
operating cost significantly decreases to (USD) $ 24,236,000, almost 85% less than the cost compared to the
traditional method. It should be noted that the culture medium used for Nostoc ellipsosporum offers better
conditions for protein synthesis and opens the way to future studies that standardize profitable methods in the
production of this lectin.

- The Effects Of Urbanization Towards Social And Cultural Changes Among West
African Countries
Authors: Dr. KM Ashifa
Pages: 212 - 218
Abstract: The West Africa society is rapidly becoming Urban as a result of multitude push and pull factors going on in West
Africa. The study examines the rhythm of urban life marked by collective consumption which influences cultural
values, pervades dressing styles of the wider social environment and health in West Africa. This has also generated
urban health crises among city dwellers and the rural areas. The review showed that the pace of urbanization is
unprecedented with cities such as Lagos having annual urban growth rate of 5.8%. Urbanization in West Africa is
mainly demographically driven without commensurate socioeconomic dividends and benefits to the urban
environment. This has created urban health crises of inadequate water safe supply, squalor and shanty settlements,
sanitation, solid waste management, double burden of diseases and inefficient, congested, and risky transport
system. In conclusion, when managed carefully, urbanization could reduce hardship and human suffering; on the
other hand, it could also increase poverty and squalor. Some laws need to be amended to change the status of poor
urban settlements. Urban health development requires intersectoral approach with political will and urban renewal
program to make our urban societies sustainable that promote healthy living.

- Development In The Scavenging Efficiency Of H2S Scavengers In Oil And Gas
Industry
Authors: Ismail A. Elhaty
Pages: 219 - 229
Abstract: Hydrogen sulfide H2S is an acid gas present in oil and gas reservoirs. The presence of H2S reduces the quality of
natural gas. Hydrogen sulfide scavengers are widely used in the production and processing operations in the Oil and
Gas Industry to maintain the integrity of the pipelines and workplace safety. Scavengers are divided into regenerative
and non-regenerative. In degenerative scavengers, concentrated solutions of aqueous alkanolamines are the most
employed for H2S removal from natural gas. Non regenerative scavengers include triazines, amine based, aldehydes,
metal chelates and others. Triazines represent the most widely used non regenerative scavengers due to their high
efficiency, fast kinetics, and low toxicity. This paper includes the up to date development in the field of H2S
scavengers used to minimize or eliminate the various problems caused by hydrogen sulfide during oil and gas drilling
operations. The advantages and disadvantages of such scavengers will be compared.
