It studies into viewpoints of 7 doctors of Wenbing studies on macula. The results concerning characteristics, remedy and prevention of macula are as follows; Macule does not protrude on the surface of skin and does not have any color change for external stimulus, but rash out on the surface and becomes white when pushed. It becomes macule when the blood leaks beneath skin as stomach-heat of yangming enters into blood system and damages it. On the other hand, when heat enters lung meridian, penetrates beneath the skin and congeals inside the vessel, it becomes rash. When you combine symptoms of body and pulse with numbers, color, shape and distribution status of macula, you can diagnose the depth of rash, seriousness, the possibility of treatment and prognosis of macula. The remedy for macule consists of cooling heat of yaming, removing heat from the blood and relieving feverish rash, and the one for rash consists of facilitating meridian with aroma, expelling pathogenic factors from muscles with drugs of pungent flavor and cool nature and clearing away heat from the blood systems. It relieves the inhibited functional activities of lung-Ki, and helps extermination of rash as well as clearing heat of the vessel. Also, it is the most important to preserve resin of stomach for every treatment. It is good to avoid expelling pathogenic factors with drugs of pungent flavor and warm nature, raising drugs and invigorating drugs during treating macula. Moreover, the patients should not over dose cold-natured drugs and purgative therapy. There are common clinical symptoms of macula in advance, so right recognition of symptoms can contribute to prevention of macula.

We present a secondary camera optimization method that helps the user exploring 3D virtual environment to precisely observe possible collisions between objects. The first role of our secondary camera is to automatically detect the area with the greatest possible collision. The second role is to show the detected area from a new angle of view that the current main camera cannot show. However, as the shapes of target objects are complex, the shape of the empty space between objects is also complex and narrow. It means that the space for the secondary camera position is highly constrained and its optimization can be very difficult. To avoid this difficulty and increase the efficiency of the optimization, we first compute a bisector surface between two target objects. Then, we limit the domain of the secondary camera's position on the bisector surface in the optimization process. To verify the utility of our method, we built a demonstration program in which the user can explore in a 3D virtual world and interact with objects by using a hand motion recognition device and conducted a user study.
