يشكل قسم الحواضن الملاذ الآمن للخدج بعد خروجهم المبكر من رحم الأم. فهي تحتوي متطلبات الحياة الأساسية للخديج, لكنها مليئة بالضجة الصادرة عن إنذارات الأجهزة و كلام الفريق الصحي و رنين الهواتف, و إغلاق الأبواب. تتجاوز مستوى هذه الضجة ما نصحت به الأكاديمية الأمريكية لطب الأطفال في قسم الحواضن 45 dBA (decibel A-weighting). كما تحفز الضجة الجملة العصبية الودية مؤدية لعدم استقرار فيزيولوجي كاضطراب مستوى الأكسجة. وجدنا في هذه الدراسة التي أجريت على 30 خديج باختبار قبلي و بعدي أن متوسط الضجة خلال ساعة من المراقبة و عدم التداخل لخفض الضجة قد بلغ 67.2 dBA, و تناسب مستوى الأكسجة عكسا مع مستوى الضجة, و أن خفض الضجة لمدة ساعة من الزمن دون 45 dBA قد رفع متوسط الأكسجة بشكل ملحوظ. لذلك تشير هذه الدراسة إلى ضرورة جعل إجراءات خفض الضجة ضمن الممارسات التمريضية اليومية, و إجراء أبحاث لاحقة لدراسة تأثير الضجة على باقي مؤشرات الخديج الحيوية.
Nursery ward is the safe place for premature after deliverey . It contains the basic requirements of life to him. but full of noise caused by alarms of devices, conversations of health team, ringing phones, and close the doors, exceeds what is recommended by the American Academy of Pediatrics in the Nursery wards 45 dBA (decibel A-weighting). Although it stimulates the autonomic system leading to physiologic instability like disorder in the level of oxygenation. We found in this study conducted on 30 premature with pre and post test, that the level of noise within first hour of non interventions reached 67.2 dBA, level of oxygenation inversely with noise level in it, and reduction of noise level under 45 dBA at second hour increases the oxygenation significantly. so we suggests to make reduce noise interventions within daily practices of nursing procedures, and subsequent research to study effect of noise on the rest of vital premature indicators.

Preterm birth is the leading cause of death for children under one year of age, and the main reason for the child to enter the incubator. Despite medical advances and technical winning in the care of premature infants., but they are exposed in Nurser
y Ward for environment stimuli not compatible with their level of developmental and evolutionary such as high levels of light and the noise that exceed the recommended levels in Nursery Ward. This leads to stress reactions by premature immature systems. demonstrating in one of their faces instability in vital indicators especially heart rate and oxygenation which may submit him for a short or long-term injuries .
Aim of the study:
Determine the effect of reducing the level of light and noise intensity in environment of Nursery Ward on the heart rate and oxygenation for premature infants.
Materials & Methods:
This true experimental design study of before and after on a sample of 30 premature acceptable in the Nursery Ward in Albasel Hospital in Tartous. they were selected in simple random way. Data were collected using a list to record demographic and health information for the mother and premature. reads of light-meter and noise-meter sitting beside the premature incubator, and reads of Oxy-meter connected to the premature wrist. was taken to every 5 minutes in each phase of the four phases, 60 minutes for each one, and conducted in the same day.1) Non intervention phase. 2) reduce light Intensity without noise Intensity reduction phase.3) reduce noise Intensity without light Intensity reduction phase.4) reduce light and noise Intensity together phase. These data were collected and analyzed using appropriate statistical programs.
Results:
This study showed a significant decrease in the mean of heart rate and a significant increase in the mean of oxygenation in the last three phases, compared with means in the first phase. This reduction and increase in the means was larger significantly in the fourth stage compared with the second and third phases. That because reducing light and noise will reduce its physiological stress to premature thus lower the pulse rate and increasing oxygenation. We can thus reduce the use of light and noise measures to improve the care environment for premature.
Two experiments were couducted to study the effect of reducing the level of
animal protein on the carcass quality of broilers. Eight hundred birds used in
the first experiment were divided into ٤ groups and left under ٣ feeding stages.
Four hundre
d birds used in the second experiment were divided into two others
groups and left under two feeding stages.
The research aims to take advantage of the solar energy, as a free energy, to run a water pump powered by solar energy, and to study the effect of the intensity of solar radiation on the performance of this pump in Syrian coast conditions. This resea
rch has explained the necessary mechanism for determining the capacity of the pump and the electric PV panels required for the work of the pump and the area of these panels. Studying
the effect of intensity of solar radiation on the performance of water pump through studying the impact of pump altitude and solar radiation intensity on water flow range at experiment location. It demonstrated that the flow of the pump is going through two phases with the increasing values of solar radiation during the day. It was found that the increasing value of the flow of the pump before the value of (520W/m2) of Solar radiation was greater than that after (520W/m2) and this led to the loss of a part of the solar energy falling during the day, especially on sunny days, and the value of the loss was about (27%) of the
total amount of solar energy falling per day.
This study aims at identifying the level of the verbal aggression of children both at
home and in the refuge accommodation centers during the wartime of Syria. In addition, it
investigates the difference between the two genders ,of both samples, in
their practicing of
verbally aggressive behavior.
The researcher has applied the descriptive research method as it conforms to the aim and
nature of the research.
The research has been conducted in 2017 and the instruments of research have been
applied in June, 2017 in Lattakia, Syria. The community of that survey included children
brought up both at home and at the refuge accommodation centers ranging from 7 – 10
years old in Lattakia. The sample children were 120 male and female children divided
equally in half i.e. 60 children per sample. The refuge accommodation center has been
chosen randomly from the accommodation centers of Lattakia like the Stadium
Accommodation Center, Harem accommodation center, the Accommodation center of
"Jihad Mashi" in addition to some neighborhoods of the afore-mentioned city which serves
the purpose of the study.
The researcher has developed a research standard to estimate the verbal aggression
which conforms to the nature of study and the surrounding conditions. This standard has
been later examined and authenticated after being modified.
The researcher has attempted to investigate five hypothesis then reached the following
conclusions:
1.There is an essential difference in the level of verbal aggression between the two
samples; children at home are less verbally aggressive than those at the accommodation
centers.
2.There are no statistically significant gender differences between males and females
in the use of verbal aggression in the case of the children brought up at home and the
children brought up at refuge accommodation centers.
3. There are no statistically significant differences among males in the use of verbal
aggression in both samples (the children at home and at refuge accommodation centers.)
4. There is a statistically significant difference among females in the use of verbal
aggression in both samples (the children at home and at refuge accommodation centers.).
The standard treatment for superficial TCC of the bladder is the endoscopic
resection of all visible tumours. Transurethral resection (TUR) may fail to control superficial disease,
especially in patients with higher tumour stages (T1), in addition
to the high recurrence rate.
To evaluate the role of a second transurethral resection (early re-resection) in reducing the high
recurrence rate of T1 bladder tumours .
