پیش لفظ

جدید انسان کی سرمایہ دارانہ اور مادیت پسند فکر نے قدرتی ماحول اور قدرتی وسائل کا بری طرح استحصال کیا ہے اور حیاتِ انسانی وحیوانی کی بقا کو تباہی کے دہانے پر پہنچا دیا ہے۔ حضرت انسان کی غفلت اور لا پرواہی سے قدرتی وسائل و ذرائع کی بقا کا مسئلہ اس وقت پوری دنیا کے لئے سنگین شکل اختیار کرگیا ہے۔یہ بات روز ِروشن کی طرح عیاں ہے کہ جدید انسان نے ماحول اور اس میں پائے جانے والے قدرتی وسائل کے تحفظ کو یکسر نظرانداز کردیا ہے ۔ جس کی بنا پر قدرتی وسائل ہوا، پانی ،معدنیات، حیوانات ،نباتات اور زمین کی طبعی ، کیمیائی اور حیاتیاتی خصوصیات میں ناپسندیدہ اور نامناسب تبدیلیاں پیدا ہو تی جار ہی ہیں، اس طرح ماحولیاتی تبدیلی( Climate Change ( ، گلوبل وارمنگ (Global Warming) اور ماحولیاتی آلودگی (Environmental Pollution ) کا مسئلہ پیداہوگیا ہے۔ ٹریٹمنٹ پلانٹس کی تنصیب کے بغیر نئے نئے کارخانےقائم ہورہے ہیں۔ ان صنعتی اداروں میں ماحولیاتی سہولیات کی عدم موجودگی کی وجہ سے ماحول میں گرین ہاؤسز گیسزکی مقدار بڑھتی جارہی ہے اور یوں قدرتی ماحول بری طرح متاثر ہورہاہے۔

 یہ بات طے شدہ ہے کہ اللہ تعالیٰ کی تخلیق کردہ ضروریات حیات یعنی قدرتی وسائل میں سے ہوا،پانی ،نباتات ،حیوانات، صاف ماحول پر انسانی زندگی کا انحصار اتنا زیادہ ہے کہ ان کے بغیر کوئی انسان زندگی گزارنے کا تصور بھی نہیں کر سکتا ۔ جبکہ عالمی سطح پر موسمیاتی تبدیلیوں کے اثرات ہر گزرتے دن کے ساتھ ساتھ شدید سے شدید تر ہوتے جارہے ہیں ۔ ایک تازہ ترین عالمی تحقیقی رپورٹ بتاتی ہےکہ عالمی موسمیاتی تبدیلی سے 2 دہائیوں میں عالمی معیشت کو 16 ہزار ارب ڈالر کا نقصان پہنچ چکا ہے۔ستم ظریفی کی بات یہ ہے سب سے زیادہ جانی و معاشی نقصان ترقی...

Analysis of Quarantine Service Quality on Ship Crew Satisfaction during the Covid-19 Pandemic at Belawan Sea Port

This study aims to analyze the quality of quarantine services on ship crew satisfaction during the Covid-19 pandemic at the Belawan Sea port. This study is a quantitative study with a cross sectional method which aims to analyze the quality of quarantine services on satisfaction during the COVID-19 pandemic at the Belawan Sea Port using the ServQual approach which consists of physical evidence, reliability, responsiveness, assurance, and empathy. The results of the study are expected to provide input regarding the quality of quarantine services provided by the Class I Medan KKP to ship crews during the COVID-19 pandemic. Based on the ServQual analysis, the results show that the satisfaction of the crew of the quarantine service at Belawan Port is very satisfying with a suitability level of 107.56% (the average service / reality score is 4.00 and the expectation score is 3.72). It is suggested to improve coordination and more intensive advocacy with shipping agents as intermediaries between officers and skippers as crew so as to reduce the length of service waiting time, in order to increase the number of human resources carrying out document checks on board, involving female medical officers for health checks The crew who came from affected countries/ports to facilitate information retrieval, ordered the boarding officers to bring Personal Protective Equipment when interacting with the crew.

Fog Framework for Mobile Devices With Minimal Latency

Latency is rapidly becoming critical in cloud computing. Latest services and applications in various vertical markets requir low latency. Today every type of business networking channels is running with blazing fast speed which requires ultra-low latency within minimum time scale. The industries which are achieving the lowest latency are surviving while other slow competitors fall behind. Users are demanding real-life applications with low latency which helps them to obtain their desire services within a very limited time in their range. Networking communication relies on critical tasks such as Storage, communication, control management, and configuration, etc. to accommodate the effective communication. Cloud system with its prerequisites is developing rapidly. Cloud is a leading enabler for various communications tasks. In a congested network, the cloud is creating unbearable and unstable high latency for computerized gadgets which demand high bandwidth. This is an alarming situation for the performance of smart applications and mobile devices in a network. The flexibility of providing applications anywhere in dense network is the beauty of cloud, but this flexibility comes at the price of unstable, unpredictable high latencies which are horrific in this ultra-fast time-period. Fog brings distributed resources near to different users to support fast streaming with reducing latency. Currently, mobile devices are gaining popularity due to their mobility.Technology enhancement from cloud to fog is a computation of distributing resources at the edge where fog bring it near to different mobile users to support fast streaming with reducinglatency. Fog networks are not very dense with distantly located servers, to provide services at the edge very speedily with low latency. Fog with emerging technology is best to keep a table latency for mobile communication. Currently, heavy data is delivering and retrieving from various geographically scattered users. So, theconceptual framework of fog to minimize the latency of mobile devices is proposed. This framework of fog is willing to sponsor mobile devices with their smart applications at the edge with low latency. So, it can provide data in minimal time to analyze and respond . to validate the performance of fog conceptual framework, algorithms are also presented. To check the performance of fog framework iFogSim (simulator) is also used. Fog is willing to keep the minimum stable by cut down the traffic burden for mobile users by providing services and resources near the user.
