To be able to grow into self confident, fearless and active women, a girl must be nurtured in an atmosphere where she can be valued. However, for the average girl child in India. her prospects of all round healthy development are severely constrained. Born into a socially inhospitable environment, a girl is considered to be an expense - someone who will never contribute to the family income and at the time of her marriage will take large assets as dowry. So deeply entrenched is the ideology of sun preference, that a mother not only hopes and prays for a boy but actually fears the birth of a daughter. In India, girls are socialized from the very beginning to accept the ideology of make supremacy, which makes them a prey to discriminatory practices. This means that not only girl are socially unequipped to question the injustices done them, but in the absence of models of role and conduct, they actually propagate the dominant social and cultural values which are against their interests. Large number of the girl are allowed to die because of malnutrition and disease, which are not properly treated. Children who are working and are on the street are know as children. A street child may be defined as a minor for whom the street has become his or her habitual abode and who is without adequate protection.

Regardless of how the state's feedback control law is designed, it is almost always necessary to implement it, using estimates of the state obtained from an observer. Hence, it is necessary to insure so that the desirable properties of the state feedback design do not vanish when the state estimate are used. It is proven in linear system theory courses that the command response is unaffected by the presence of the observer. However, the response to initial conditions will affect the system output. It is suggested that the observed poles should be made faster than the state feedback poles by an amount that depends upon the level of measurement noise. These conclusions are generally based upon transient time response properties of the system, and not on feedback properties such as robustness margins, We now present a procedure for tuning an observer so that, under appropriate conditions, the feedback properties of a state feedback design are recovered.
Q. What will be done to maintain feedback properties of a state?

निर्देश: निम्नलिखित गद्यांश का ध्यानपूर्वक अध्ययन करें तथा दिए गए प्रश्न का सही उत्तर दें:
देश में पांचवें लॉकडाउन का लागू होना उतना ही जरूरी हो गया था, जितना लॉकडाउन में ढील देना। कड़ाई और ढील की मिली-जुली व्यवस्था ही समय की मांग है। प्रधानमंत्री ने मन की बात कार्यक्रम में भी इसी मजबूरी की ओर संकेत करते हुए चेताया है कि देश खुल गया है, अब ज्यादा सतर्क रहने की आवश्यकता है। वाकई सतर्कता आज प्राथमिकता है, तभी हम न केवल अपने कार्य-व्यापार को आगे बढ़़ा पाएंगे, स्वयं को सुरक्षित रखने में भी कामयाब होंगे। जाहिर है, लॉकडाउन पांच पिछले लॉकडाउन की तरह नहीं है। अब केवल कंटेनमेंट जोन में ही लॉकडाउन रखना अनिवार्य होगा। साथ ही, इस बार राज्यों की भूमिका वाकई बहुत बढ़ गई है। उन्हें अपने स्तर पर बड़े फैसले करने हैं। मध्य प्रदेश, पंजाब, तमिलनाडु, बिहार इत्यादि राज्यों ने तो लॉकडाउन को 30 जून तक बढ़ाने का फैसला कर लिया है। कुछ राज्य 15 जून तक ही लॉकडाउन के पक्ष में हैं। आज कुछ राज्य ज्यादा चिंतित हैं, तो समझा जा सकता है। पिछले लॉकडाउन की अगर हम चर्चा करें, तो 14 दिनों में ही संक्रमण के लगभग 86 हजार मामले सामने आए हैं। आंकड़ों को अलग से देखें, तो चिंता होती है, लेकिन दूसरे देशों से तुलना करें, तो अपेक्षाकृत संतोष होता है। हमारा यह संतोष कायम रहना चाहिए।
यह चर्चा जारी रहेगी कि जब देश में 500 मामले भी नहीं थे, तब बहुत कड़ाई से लॉकडाउन लगाया गया था, लेकिन जब मामले दो लाख के करीब पहुंचने लगे हैं, तब अपने पास के लोगों लॉकडाउन में ढील दी जा रही है। जब केंद्र और राज्य सरकारें ढील पर विचार कर रही थीं, तब 30 मई को संक्रमण के मामलों में रिकॉर्ड इजाफा दर्ज हुआ है। अब एक दिन में ৪,000 से ज्यादा मामले आने लगे हैं, तो आने वाले दिनों में क्या होगा? मरने वालों की संख्या भी 5,000 के पार जा चुकी है। ऐसे में, जब धर्मस्थल, रेस्तरां, होटल, शॉपिंग मॉल, स्कूल-कॉलेज खुल जाएंगे, तब क्या होगा? जब सड़कों पर सार्वजनिक वाहन दौड़ने लगेंगे, फिर क्या होगा? धर्म और शिक्षा के मंदिर देश में हमेशा से भीड़ भरे रहे हैं। ये हमारे समाज के सबसे कमजोर मोर्चे हैं, जहां संचालकों-प्रबंधकों को विशेष रूप से चौकस रहना होगा। धर्मस्थल के संचालकों की ओर से आ रहे दबाव को समझा जा सकता है, पर वहां फिजिकल डिस्टेंसिंग को सुनिश्चित रखना अच्छे संस्कार, सभ्यता की नई निशानी होगी। धर्म प्रेरित मानवता भी हमें एक-दूसरे की चिंता के लिए प्रेरित करती है। हम सभी न चाहते हुए भी एक-दूसरे को प्रभावित करते रहते हैं। कोरोना के संदर्भ में अनेक लोगों को अब यह नहीं पता चल रहा है कि उन्हें कोरोना किससे लगा? घर से निकलने वाला एक आदमी अगर अनेक लोगों के संपर्क में आएगा, तो यह पता लगाना उत्तरोतर कठिन होता जाएगा कि कोरोना की कौन-सी श्रृंखला आगे बढ़ रही है। लॉकडाउन पांच के समय देश ऐसी अनेक तरह की नई चुनौतियों की ओर बढ़ रहा है। संदिग्ध लोगों की निगरानी का काम हाथ-पैर फुला देगा। बेशक, अर्थव्यवस्था में कुछ सुधार हम देखेंगे और देश के लोगों को राहत देने के लिए यह अपरिहार्य है। ध्यान रहे, हर जगह पुलिस या सरकार खड़ी नहीं हो सकती, हमें स्वयं अनुशासित नागरिक बनकर अपनी और अपने पास के लोगों की पहरेदारी करनी है।
