Dewasa ini, whatsapp (WA) telah menjadi sosial media yang sangat penting dalam kegiatan berkomunikasi dan pembelajaran daring (e-learning).. Hal ini tidak lepas dari fitur dan fungsinya yang beranekaragam, seperti mengirim pesan, berbagi file, video, suara, dan bahkan dapat berbagi lokasi secara real-time. Penelitian ini bertujuan untuk menganalisis konten grup chat whatsapp pada mata kuliah manajemen pembiayaan pendidikan tahun 2020 di pascasarjana Universitas Negeri Semarang. Selain itu, penelitian ini juga mempunyai tujuan lain yaitu mengeksplorasi tingkat penggunaan WA oleh anggota grup. Jenis penelitian ini merupakan penelitian deskriptif kuantitatif yang analisisnya dilakukan menggunakan bantuan bahasa pemrograman Python. Hasil penelitian menunjukkan bahwa dalam 1 semester, terdapat 14 anggota grup, 606 pesan, 44350 kata, 7 link website, dan 24 karakter emoji dengan total frekuensi sebanyak 122. Adapun kata yang paling sering digunakan oleh pengguna grup adalah kata “nggih pak”. Kata ini merupakan sebuah kata dalam bahasa jawa yang digunakan apabila seseorang menyetujui sesuatu. Berdasarkan hasil penelitian, juga dapat diidentifikasi siapa anggota grup teraktif, rata – rata pesan yang dikirim oleh masing – masing anggota grup, dan kapan hari teraktif grup. Melalui analisis konten, dapat diperoleh informasi – informasi penting yang dapat membantu menunjang proses pembelajaran e-learning.

UNSTRUCTURED Covid-19 outbreak was first reported in Wuhan, China. The deadly virus spread not just the disease, but fear around the globe. On January 2020, WHO declared COVID-19 as a Public Health Emergency of International Concern (PHEIC). First case of Covid-19 in India was reported on January 30, 2020. By the time, India was prepared in fighting against the virus. India has taken various measures to tackle the situation. In this paper, an exploratory data analysis of Covid-19 cases in India is carried out. Data namely number of cases, testing done, Case Fatality ratio, Number of deaths, change in visits stringency index and measures taken by the government is used for modelling and visual exploratory data analysis.

Catecholamines are physiological regulators of carbohydrate and lipid metabolism during stress, but their chronic influence on metabolic changes in obese patients is still not clarified. The present study aimed to establish the associations between the catecholamine metabolites and metabolic syndrome (MS) components in obese women as well as to reveal the possible hidden subgroups of patients through hierarchical cluster analysis and principal component analysis. The 24-h urine excretion of metanephrine and normetanephrine was investigated in 150 obese women (54 non diabetic without MS, 70 non-diabetic with MS and 26 with type 2 diabetes). The interrelations between carbohydrate disturbances, metabolic syndrome components and stress response hormones were studied. Exploratory data analysis was used to determine different patterns of similarities among the patients. Normetanephrine concentrations were significantly increased in postmenopausal patients and in women with morbid obesity, type 2 diabetes, and hypertension but not with prediabetes. Both metanephrine and normetanephrine levels were positively associated with glucose concentrations one hour after glucose load irrespectively of the insulin levels. The exploratory data analysis showed different risk subgroups among the investigated obese women. The development of predictive tools that include not only traditional metabolic risk factors, but also markers of stress response systems might help for specific risk estimation in obesity patients.
