Shape
This magazine encloses each paragraph and subsection within rectangles. The rectangle shape, after all, means stability and structure, while its direction emphasizes horizontal and vertical. Not only do these add extra structure to the page, but the paragraphs and graphics conform to the rectangle's shape more easily than do circles and triangles. The rectangles also manage to enclose the separate sections, dividing the page into bite-sized portions more pleasing to the eyes of the younger readers.
Notice, too, the circle beneath Cyber-Stein. It is the only circle that the design employs, intended to be out of place and to draw the eye. The text within the circle is important information which the readers must know, hence the contrast.
Dot

The dot, as Dondis established, is the irreducibly minimum unit of visual communication. The dot, as in the case of these bullets, serves as the marker, or reference point, drawing the eye to each sequentially. In this case, dots act as bullets, separating a sequence of tips beneath a common heading. The boxes that surround them alone are insufficient, and would seem cluttered due to quantity, but the dot-bullets mark and separate each point adequately.
LinesOne of the most basic uses of the line, in magazines or in any other publication: in the table of contents. The line's energy is used to direct the eye from each section to the page; without them, the reader might easily become confused as to which page went with which section, irritating him or her and preventing them from easily referencing the section they want. Especially with the text rotated slightly, the line's decisiveness allows the user to ignore the otherwise unsettling position, making it simple different and not jarring.
(On a side-note, all the scans were taken from this month's Shonen Jump magazine; the reason for my selection being not only that my intended eventual career will be in graphics desing (specifically in Magazine design), but this month's issue contained my first freelance article. So, I'm slightly biased towards this particular magazine and issue, needless to say.)
