56% are registered in Madhya Pradesh, Chattisgarh and Punjab.
Crime against children saw a 24% increase; from 26,694 cases in
2010 to 33,098 cases in 2011. Rape cases increased by 30%,
feticide by 19% while buying of girls for prostitution declined by
65%. There is an increase of 10.5% in juvenile crimes from
2010(22,740) to 2011(25,125). As a result of such forced labor,
children are often subjected to malnutrition, impaired vision,
deformities and easy victims of deadly diseases like Tb, Cancer
and AIDS.

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts

In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

1. Introduction
The following extract from [1] provides a very good understanding of the overall LTE Network Infrastructure and elements.
UMTS overall network architecture, not only including the Evolved Packet Core (EPC) and Evolved UMTS Terrestrial Access Network (E-UTRAN), but also other relationship between them. For simplification, the picture only shows the signalling interfaces. In some cases, both user data and signalling are supported by the interfaces) but, in some other cases, the interfaces are dedicated to the Control plane, and only support signalling (like the S6 and S7 interfaces).
2. The new blocks specific to Evolved UMTS evolution, also known as the Evolved Packet System (EPS), are the Evolved Packet Core (or E-UTRAN). Other blocks from the classical UMTS architecture are also displayed, such as the UTRAN (the UMTS Access Network), the respectively, connected to the public (or any private) IP and Telephone Networks. The IMS (IP Multimedia Subsystem) is located on top provide access to both public or private IP networks, and the public telephone network via Media Gateway network entities. The information is shown as a central node, providing services to all Core Network blocks of 3G and evolved 3G architecture.
Note: The picture does not represent the nodes involved in the support of charging function.
Discussed below are the individual sub-components:
2. E-UTRAN and eNode Bs
2.1. History from UMTS
From the first releases of the UMTS standard, the UTRAN architecture was initially very much aligned with 2G/GSM Access Network architecture follows the good old 2G/GSM ‘star’ model, meaning that a single controller (the RNC) may possibly control a large commercial networks is about several hundreds – of radio Base Stations (the Node B) over the Iub interface. In addition, an inter-RNC Iur UTRAN call anchoring at the RNC level and macro-diversity between different Node B controlled by different RNCs. Macro-CDMA-based UTRAN physical layers, as a means to reduce radio interference and preserve network capacity. The initial UTRAN architecture Node B implementation, and a relatively complex, sensitive, high capacity and feature-rich RNC design. In this model, the RNC had management features as well as a significant part of the radio protocols.
2.2 eNode Bs: The Single E-UTRAN Node
Compared with UTRAN, the E-UTRAN OFDM-based structure is quite simple. It is only composed of one network element: the eNodeB RNC (Radio Network Controller) inherited from the 2G BSC (Base Station Controller) has disappeared from E-UTRAN and the eNodeB Network using the S1 interface. As a consequence, the features supported by the RNC have been distributed between the eNodeB Serving Gateway entities.
2.3 The X2 Interface
A new interface (X2) has been defined between eNodeB, working in a meshed way (meaning that all Node Bs may possibly be linked together). this interface is to minimize packet loss due to user mobility. As the terminal moves across the access network, unsent or unacknowledged eNodeB queues can be forwarded or tunnelled to the new eNodeB thanks to the X2 interface. From a high-level perspective, the new moving towards WLAN network structures and Wifi or WiMAX Base Stations.
2.4 eNode B Functionalities
Functional definition eNodeB as WLAN access points – support all Layer 1 and Layer 2 features associated to the E-UTRAN OFDM directly connected to network routers. There is no more intermediate controlling node (as the 2G/BSC or 3G/ RNC was).
architecture (fewer nodes of different types, which means simplified network operation) and allows better performance over the Chapter 4, the termination of Layer 2 protocols in eNodeB rather than in the RNC helps to decrease data-transmission latency by transmission of packet repetitions over the Iub interface. From a functional perspective, the eNodeB supports a set of legacy features, procedures for transmission and reception over the radio interface:
· Modulation and de-modulation.
· Channel coding and de-coding.
Besides, the eNodeB includes additional features, coming from the fact that there are no more Base Station controllers in the E-UTRAN which are further described in Chapter 4, include the following:
· Radio Resource Control: this relates to the allocation, modification and release of resources for the transmission
over the radio interface between the user terminal and the eNodeB.
· Radio Mobility management: this refers to a measurement processing and handover decision.
3. · · Radio interface full Layer 2 protocol: in the OSI ‘Data Link’ way, the layer 2 purpose is to ensure transfer of data
between network entities. This implies detection and possibly correction of errors that may occur in the physical layer.
3. Evolved Packet Core (EPC) and its Components
The EPC (Evolved Packet Core) is composed of several functional entities:
· The MME (Mobility Management Entity)
· The HSS (Home Subscriber Server)
· The Serving Gateway.
· The PDN Gateway (Packet Data Network).
· The PCRF (Policy and Charging Rules Function) Server.
The following sub-sections discuss each of these in detail:
3.1 MME (Mobility Management Entity)
The MME is in charge of all the Control plane functions related to subscriber and session management. From that perspective, the MME · Security procedures – this relates to end-user authentication as well as initiation and negotiation of ciphering and integrity protection
· Terminal-to-network session handling – this relates to all the signalling procedures used to set up Packet Data context and like the Quality of Service.
· Idle terminal location management – this relates to the tracking area update process used in order for the network to be incoming sessions.
The MME is linked through the S6 interface to the HSS which supports the database containing all the user subscription information.
3.2 HSS (Home Subscriber Server)
The HSS (Home Subscriber Server) is the concatenation of the HLR (Home Location Register) and the AuC (Authentication Center) – two present in pre-IMS 2G/GSM and 3G/UMTS networks. The HLR part of the HSS is in charge of storing and updating when necessary the database subscription information, including (list is non exhaustive):
· User identification and addressing – this corresponds to the IMSI (International Mobile Subscriber Identity) and MSISDN (Mobile mobile telephone number.
· User profile information – this includes service subscription states and user-subscribed Quality of Service information (such allowed traffic class).
The AuC part of the HSS is in charge of generating security information from user identity keys. This security information is provided to communicated to other entities in the network. Security information is mainly used for:
· Mutual network-terminal authentication.
· Radio path ciphering and integrity protection, to ensure data and signalling transmitted between the network and the terminal altered.
3.3 The Serving GW (Serving Gateway)
From a functional perspective, the Serving GW is the termination point of the packet data interface towards E-UTRAN. When terminals E-UTRAN, the Serving GW serves as a local mobility anchor, meaning that packets are routed through this point for intra E-UTRAN 3GPP technologies, such as 2G/GSM and 3G/UMTS.
3.4 The PDN GW (Packet Data Network Gateway)
4. Similarly to the Serving GW, the PDN gateway is the termination point of the packet data interface towards the Packet Data point for sessions towards the external Packet Data Networks, the PDN GW also supports Policy Enforcement features (which rules for resource allocation and usage) as well as packet filtering (like deep packet inspection for virus signature detection) support (like per URL charging).
3.5 The PCRF (Policy and Charging Rules Function) Server
The PCRF server manages the service policy and sends QoS setting information for each user session and accounting rule information. functionalities for the following two UMTS nodes:
· The Policy Decision Function (PDF)
· The Charging Rules Function (CRF)
The PDF is the network entity where the policy decisions are made. As the IMS session is being set up, SIP signalling containing media between the terminal and the P-CSCF. At some time in the session establishment process, the PDF receives those requirements from the based on network operator rules, such as:
· Allowing or rejecting the media request.
· Using new or existing PDP context for an incoming media request.
· Checking the allocation of new resources against the maximum authorized
The CRFs role is to provide operator-defined charging rules applicable to each service data flow. The CRF selects the relevant charging provided by the P-CSCF, such as Application Identifier, Type of Stream (audio, video, etc.), Application Data Rate, etc.
