Most Common HTML Entity For Technical Documentation Tree Structure

Technical Documentation Tree Structure ( Box-drawing characters ) therefore typically only work well with monospaced fonts. If you write your task structure, it can be easier to maintenance and take care your task structure.
. . "Full Stop" is type before root.
├ "Box Drawings Light Vertical and Right" is type at folder or file that has the other folders in the same level/branch structure.
─ "Box Drawings Light Horizontal" to connect between ├ and space bar and folder or file name.
│ "Box Drawings Light Vertical" to connect the branch line vertically.

└ "Box Drawings Light Up and Right" to connect the last folder or last file, also can be used at the time there are an empty folder.

Manfaat Berolah Raga

Pengertian Olahraga adalah semua bentuk aktivitas fisik. Olahraga pada umumnya bertujuan untuk memelihara atau meningkatkan kemampuan dan keterampilan fisik.

Jenis Olahraga

  • Lari atau jogging adalah olahraga kardiovaskular yang efektif untuk meningkatkan daya tahan dan kebugaran jantung.
  • Bersepeda atau bicycling baik dalam membantu meningkatkan kekuatan otot, daya tahan, dan melatih sistem kardiovaskular.
  • Renang atau swimming merupakan olahraga yang menggerakkan seluruh tubuh, sehingga melatih kekuatan otot dan daya tahan.
  • Senam akan membuat Anda lebih bersemangat dan dapat meningkatkan detak jantung serta membangun otot. Melakukan kegiatan senam dapat disertai dengan lagu favorit.
  • Latihan Angkat Beban atau Light Dumbbell Workout 
  • Lompat Tali atau Skipping bermanfaat untuk mengurangi cedera kaki, membakar kalori, meningkatkan koordinasi tubuh, menyehatkan jantung, serta meningkatkan efisiensi pernapasan. 
Jenis Olahraga di atas bersifat rendah dampak dan umum sehingga cocok untuk semua usia. Jenis Olahraga di atas juga dapat dilakukan oleh orang-orang sibuk yang kadang sulit sekali mencari waktu untuk berolahraga secara teratur karena dapat dilakukan di dalam rumah atau di sekitar rumah.

Risiko Berolahraga

Ketika berolahraga, tentu Anda memiliki risiko untuk cedera, baik itu ringan atau berat. Karena itu, penting bagi setiap individu ( orang-orang di masyarakat sekitar ) untuk menerapkan cara olahraga yang tepat dan tidak berlebihan sebagai upaya menghindari risiko cedera 

Cara Mencegah Risiko Dalam Berolahraga

Ada beberapa cara yang dapat Anda lakukan untuk mencegah cedera dalam berolahraga sehingga hasil olahraga Anda menjadi maksimal. Di antaranya adalah sebagai berikut:
  1. Persiapan Diri Dan Persiapan Alat
    Untuk mencegah terjadinya risiko cedera dalam berolahraga, persiapkan diri Anda dengan istirahat dan nutrisi (asupan gizi) yang cukup dan seimbang. Bila kondisi tubuh dalam keadaan tidak fit, kurang tidur, sedang menjalani diet ketat dan sebagainya, sebaiknya segera periksa dan konsultasi kepada ahli kesehatan. Persiapkan pula alat olahraga dan peralatan pelindung (seperti helm, sarung tangan, sepatu, dan sebagainya) dalam kondisi sebaik mungkin untuk menghindari cedera.
  2. Pemanasan
    Pemanasan akan membantu Anda mencegah risko, di antaranya ketegangan pada otot. Sebelum berolahraga, terutama yang berintensitas tinggi, jangan lupa untuk pemanasan, ya!
  3. Istirahat dan Nutrisi yang cukup
    Istirahat yang cukup dan memenuhi asupan gizi yang seimbang dan tercukupi.
  4. Pemanasan
    Pemanasan mempersiapkan tubuh untuk aktivitas fisik yang lebih berat dengan meningkatkan aliran darah dan suhu tubuh. Mulailah dengan peregangan ringan dan dinamis untuk meningkatkan mobilitas sendi dan fleksibilitas otot. Contohnya: gerakan memutar kepala, bahu, dan pinggul, serta langkah-langkah ringan.
  5. Pendinginan
    Pendinginan membantu memulihkan otot dan mencegah rasa kaku. Selesai aktivitas, luangkan waktu untuk pendinginan. Lakukan peregangan statis dengan menahan posisi selama 15-30 detik untuk meningkatkan fleksibilitas dan mengurangi risiko cedera otot.
  6. Pahami dan Pelajari Tekniknya
    Melakukan latihan kekuatan otot dan ketahanan tubuh, seperti sit-up, push-up, dan angkat beban tanpa mengetahui teknik yang tepat untuk melakukannya. Selain itu, jenis olahraga ini juga tidak dianjurkan bagi seseorang yang memiliki riwayat penyakit jantung jika dilakukan secara berlebihan.
  7. Latihan dengan aman :
    Melakukan latihan dengan teknik yang benar, pastikan anda memahami teknik yang benar untuk setiap aktivitas fisik yang Anda lakukan. Jika perlu, mintalah bimbingan dari instruktur atau pelatih yang berpengalaman. Memulai dengan Intensitas Rendah dan secara bertahap tingkatkan seiring waktu. Hal ini membantu tubuh beradaptasi.

Cara Menangani Risiko Berolahraga

Orang yang mengalami cedera olahraga sebaiknya langsung menghentikan aktivitasnya untuk memeriksa kondisi cedera yang dialami. Terutama jika merasa sakit, memar, bengkak, atau sulit bergerak. Kadang beberapa gejala ini baru terasa beberapa menit atau jam setelah berolahraga. Jika memaksakan diri terus berolahraga, cedera bisa makin parah dan lebih sulit disembuhkan.

Jika hanya mengalami cedera minor, seperti lecet atau memar, Anda bisa merawatnya sendiri di rumah. Karena itu, penting untuk menyediakan kotak P3K atau pertolongan pertama pada kecelakaan. Penanganan cedera olahraga tergantung jenis cedera yang dialami. Bila ragu, cara terbaik untuk menangani cedera adalah membawanya ke fasilitas pelayanan kesehatan terdekat. Karena Beberapa jenis cedera olahraga membutuhkan penanganan medis oleh profesional.

Manfaat Berolahraga

Berikut ini adalah beberapa manfaat lain dari olahraga bagi tubuh seseorang, di antaranya adalah:
  • Menormalkan kadar kolesterol di dalam tubuh.
  • Membakar kalori di dalam tubuh
  • Menyehatkan jantung.
  • Mencegah terjadinya obesitas.
  • Mengurangi stres.
  • Menaikkan sistem imun untuk mencegah penyakit.

CSV On The Web 1

CSV ( Comma Separated Values ) is one of the most popular formats for publishing data on the web. It is concise, easy to understand by both humans and computers, and aligns nicely to the tabular nature of most data.
But there is no mechanism within CSV to indicate the type of data in a particular column, or whether values in a particular column must be unique. It is therefore hard to validate and prone to errors such as missing values or differing data types within a column.

Tabular data is any data that can be arranged in a table, like the one here:

Example Table Data or Tabular Data

column 1 column 2 column 3
row 1 cell in column 1 and row 1 cell in column 2 and row 1 cell in column 3 and row 1
row 2 cell in column 1 and row 2 cell in column 2 and row 2 cell in column 3 and row 2
row 3 cell in column 1 and row 3 cell in column 2 and row 3 cell in column 3 and row 3


A CSV file writes each row on a separate line and each cell is separated from the next with a comma. The values of cells can be written with double quotes around them; this is necessary when a cell value contains a line break or a comma.

Example Easy CSV file

cell in column 1 and row 1,cell in column 2 and row 1,cell in column 3 and row 1
cell in column 1 and row 2,cell in column 2 and row 2,cell in column 3 and row 2
cell in column 1 and row 3,cell in column 2 and row 3,cell in column 3 and row 3

Example CSV file With Double Quotes Around Cell Values:

"cell in column 1 and row 1","cell in column 2 and row 1","cell in column 3 and row 1"
"cell in column 1 and row 2","cell in column 2 and row 2","cell in column 3 and row 2"
"cell in column 1 and row 3","cell in column 2 and row 3","cell in column 3 and row 3"

Example CSV file that contains a header row:

"country","country group","name (en)","name (fr)","name (de)","latitude","longitude"
"at","eu","Austria","Autriche","Österreich","47.6965545","13.34598005"
"be","eu","Belgium","Belgique","Belgien","50.501045","4.47667405"
"bg","eu","Bulgaria","Bulgarie","Bulgarien","42.72567375","25.4823218"

Example CSV file 

Column titles are a type of annotation on a column, not part of the data itself. For example, they aren't included when you're counting the rows of data in a table:

column 1 column 2 column 3 column 4 column 5 column 6 column 7
titles country country group name (en) name (fr) name (de) latitude longitude
row 1 AT eu Austria Autriche Österreich 47.6965545 13.34598005
row 2 BE eu Belgium Belgique Belgien 50.501045 4.47667405
row 3 BG eu Bulgaria Bulgarie Bulgarien 42.72567375 25.4823218

CSV Metadata File

Example the simplest CSV metadata file in JSON

 you can create a single table description in JSON file (for file name e.g. countries.json) and looks like:
{
  "@context": "http://www.w3.org/ns/csvw",
  "url": "countries.csv"
}
Metadata files must always include the @context property with a value "http://www.w3.org/ns/csvw": this enables implementations to tell that these are CSV metadata files. The url property points to the CSV file that the metadata file describes.

NOTE

These metadata documents should be served from a web server with a media type of application/csvm+json if possible.

Example the table contains seven columns named

table metadata in JSON as they are in this CSV file like so:
{
  "@context": "http://www.w3.org/ns/csvw",
  "url": "countries.csv"
  "tableSchema": {
    "columns": [{
      "titles": "country"
    },{
      "titles": "country group"
    },{
      "titles": "name (en)"
    },{
      "titles": "name (fr)"
    },{
      "titles": "name (de)"
    },{
      "titles": "latitude"
    },{
      "titles": "longitude"
    }]
  }
}

Where Is The Enter Key?

  • The most common form of the Enter key is a rectangular key located in the lower-right corner —to the right of the 3 (three cardinal number) and . (period or full stop or dot) keys (of the numeric keypad)— of  the main keyboard section. Some enter key of the keyboards may have a larger L-shaped Enter key.
  • While the return key is situated on the right edge of the main alphanumeric portion of the keyboard. Some return key of the keyboards may have a larger L-shaped Enter key.

Vertical Multiplication Example


  1. Set up the vertical multiplication by stacking the factor numbers vertically and lining up the digits by place value.
  2. Draw a multiplication symbol "x" to the rightt of the bottom number and a horizontal line underneath the most bottom number.
  3. We start our multiplication with the ones' place digit (rightmost) in the bottom column. We will multiply this digit by each digit in the top number working right to left.
  4. After each multiplication, we write the answers below the horizontal line working right to left. The placement here is very important to maintain the proper place value.

Long Division Example

Long Division is a mathematics method for dividing large numbers, which breaks the division problem into multiple steps following a sequence.

Step 1

place every long division part into each place.
  • Divisor number in the left side of pipe bar / vertical bar.
  • Dividend number in the right side of pipe bar and under the overbar.
  • Quotient number in the above side of vinculum / overbar.

Step 2

  • Take the first digit of the dividend from the left. Check if this digit is greater than or equal to the divisor number.
  • Then divide it by the divisor number and write the answer on top as the quotient number.
  • Then multiply the divisor number with quotient number so you get the result digit.
  • Then subtract the result digit from the  dividend number and write the difference number below.
  • In this example the difference number is zero so there is no remainder.
