We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

DESIGN OF SYSTEM SOFTWARE
A.
Acquisition of Environmental Monitoring Data
As for the design of the Intelligent Lab Monitoring
System, we need to implement the local storage and dynamic
update of the data collected by sensor networks for the
achievement of local management and remote publishing of
environmental data, which can be implemented through an
embedded web server. The remote monitoring client browser
posts a HTTP request and then CGI programs operate
SQLite database. The System software architecture is shown
in Figure 3.
Figure 2. The system hardware architecture
B. Sensor Networks
We use MEGA 8 as the master chip of the sensor
extension board, which is connected to various types of
sensors to constitute a sensor network. This network collects
environmental data and transmits them to the ARM
Intelligent Monitoring Center through serial ports. The
sensor network includes DS18B20 temperature sensor,
HSll01 humidity sensor, TGS822 alcohol sensors, E200B
infrared sensors and TGS4161 carbon dioxide sensor. These
sensors automatically monitor the temperature, humidity,
carbon dioxide and other gas concentrations as well as the
availability of external material intrusion in the laboratory.
C. Design of GPRS Module
This system uses SIM100-E GSM / GPRS dual-band
module for voice transmission, messages and data services. It
provides wireless interface and communicates with the ARM
Intelligent Monitoring Center through the RS232 interface
.We write AT commands into the serial device file and
control the GPRS module to achieve functions such as the
SMS / MMS mode automatic alarm to the managers when an
exception occurs with the laboratory monitoring data.
Figure 3. The system software architecture
The well-known open-source database SQLite which
abandons many complex features of traditional enterprise
database and only implements the necessary functions in
terms of a basic database is one of the most widely used
embedded database [4-5].The system overhead is small and it
has retrieval efficiency, supporting ACID properties and
SQL92 standard. This system uses SQLite database on the
embedded Linux operating system to manage data.
The ARM Intelligent Monitoring Center acquires sensor
data via the sensor expansion board. The sensor expansion
board with Mega8 as its master chip is used for data
acquisition and communicating with intelligence monitoring
center. SCM software is in charge of the local polling to
obtain the status of each sensor and monitoring data. It can
send out an interrupt request signal. The ARM Intelligent
Monitoring Center sends control commands to SCM
according to the definition of serial communication protocol,
the latter returns the state or data of specified sensors
according to the commands. The sensor data is acquired and
updated in a fixed time interval managed by SQLite
database.
D. Webcams
Most of the current securities monitoring system are
based on PC with cameras, which is costly and troublesome
to implement. This system uses an embedded host to connect
cameras, which handles the real-time image acquisition and
image capture of laboratory environment. Through image
processing and special algorithm [3], the images can be used
to determine whether an exception illegal invasion event
occurs. In conjunction with infrared detectors for functional
complementation, the system has better implementation of
security features.
In addition, the ARM Intelligent Monitoring Center can
also control a variety of electrical equipments in the
laboratory and is equipped with a TFT LCD touch screen, on
which a friendly GUI developed by QT runs under
embedded Linux system.
B. Environmental Monitoring Data Analysis Algorithm
The environmental monitoring data analysis algorithm
analyzes the current data stored in the SQLite database
173

threshold value. If there is an exception for the sensor data in
comparison with the threshold, then the system will call the
GPRS module and electrical device driver functions to make
corresponding processing such that when the temperature is
too high, we may think a big fire must be caused .So the
system sends an alarm message to the user, dial the phones,
cut off the power of large electrical equipments at the same
time. The photos which record the accident scene will be
saved in the root directory of the boa web server in order to
provide the proof of the cause of the accident. The flow chart
of the environmental monitoring data analysis algorithm is

process in the background. When users send requests
through IE browsers to the local embedded web server to
start the corresponding CGI program to accomplish the
parsing and processing of the parameters, the web server
translates the request parameters into environment variables
or standard input. CGI programs perform the corresponding
query and update operations of SQLite database and the
results are converted to the format which is recognized by
the web browsers. Then they are returned to the clients as
HTTP response messages, thereby achieving the remote
query of monitoring data collected by sensor networks.
2) Remote Publishing of Video Image Data
To achieve the remote publishing of video image data we
needed to complete three steps which are image acquisition,
image compression and dynamically displays through web
pages.
Image acquisition module completes the capture of the
video images through the video device driver V4L
(video4linux) in the embedded Linux kernel.V4L is the basis
of imaging systems of Linux system and provides a range of
application programming interface function for the control of
the video devices [7].These video devices include TV cards,
video capture cards, USB cameras and so on. The flow chart
of image captures based on V4L is shown in Figure 5.

Publishing Environmental Monitoring Data Based on
the Embedded Web
To achieve the remote publishing of the sensor data and
video images, we can build an embedded web server. As for
resource-limited embedded devices the light weight web
servers we can choose are Boa, httpd, thttpd, etc. Boa is a
single-task web server which runs on UNIX /Linux system.
If there are two users’ simultaneous accesses to it, in which a
user must wait for a moment, the server creates a separate
process to handle CGI programs, taking up less
system resources. The advantages of Boa lie in its rapidity
and reliability. This system uses the open-source Boa web
server which supports CGI program. However, the principles
of remote publishing are totally different due to the
differences between the two types of environmental data.
1) Remote Publishing of Sensor Data
The remote publishing of sensor data is achieved through
the CGI technology. CGI is a standard interface for external
applications to interact with a web server [6].We transplant
embedded Linux system to the ARM Intelligent Monitoring
Center and build Boa web server, which is responsible for
listening to customer requests from the Internet as a running

The video data collected in the memory can be saved as
files and it could also be compressed for transmission
through the Internet. This design will choose to compress the
video data with the MJPEG algorithm to generate data
stream .Finally, we need to dynamically displayed the video
data on web pages, but this is difficult to be implemented
through the traditional CGI technology. Because CGI
programs run on the server, which has high demand for the
hardware resources, they increase the burden of
servers. They aren’t suitable for the embedded environment
of which the memory and storage space is very limited .This
paper develops Java Applets to achieve flexible man-

data.
Java Applets are provided by the web server and they are
downloaded to the clients when the browser accesses the
server with requests. The client browser can run the program
only if it supports Java VM. The system uses Java Applets to
provide access interfaces for users, so it is convenient to
develop client applications, reducing the burden of web
server at the same time. In the ARM Intelligent Monitoring
Center we build a small embedded website, the main content
of which is monitored environmental data and information of
video images.
The process of the service provided by the embedded
website of the Laboratory Intelligent Monitoring System is
shown in Figure 6.

CONCLUSION
This paper focuses on solving the issues of poor real
time, high cost, low precision and incapability of
determining whether the lab environment is in line with the
body’s health in the laboratory management of domestic
institutions of higher learning and designs an embedded
web-based remote monitoring system to realize the local
management and remote publishing applications for largescale dynamic data of sensor networks and video
images. Build an embedded web server to publish the data
of sensor networks and video images to achieve remote
monitoring which is based on B / S architecture. Managers
can achieve remote monitoring for devices in the laboratory
through a web browser which is cross-platform. The
experimental results show that the system designed realizes
safe and convenient remote monitoring and local
management of the environment in laboratories and has high
availability, reliability and popularization.

information which is implemented by the combination of
embedded database SQLite and an embedded boa web server
is shown in Figure 7 .It can realize the remote access of
sensor monitoring data and video image information in the
laboratory, supporting the query of the historical records and
download of the environmental monitoring data to the client
according to requests. The remote video monitoring centers
can implement both real-time image monitoring and the
query of the photo image files automatically captured when
the monitoring system in abnormal states.
