Input: PHOTOGRAPH COLLECTING gains new stature as prices rise. Price records are being set at auctions this week. At Christie's, a folio of 21 prints from Alfred Stieglitz's "Equivalents" series sold for $396,000, a single-lot record. Other works also have been exceeding price estimates. In part, prices reflect development of a market structure based on such variables as the number of prints. This information used to be poorly documented and largely anecdotal, says Beth Gates-Warren of Sotheby's. "There is finally some sort of sense in the market," she says. Corporations and museums are among the serious buyers, giving greater market stability, says Robert Persky of the Photograph Collector. "When I see prints going into the hands of institutions, I know they aren't going to come back on the market." Most in demand: classic photographs by masters such as Stieglitz and Man Ray. But much contemporary work is also fetching "a great deal of money," says Miles Barth of the International Center of Photography.

The dermis is the inner layer of skin. The dermis has blood vessels and nerve endings. The nerve endings explain why your skin is sensitive. You can sense pain, pressure, and temperature. You cut your finger and it starts to bleed. What has happened? If your skin bleeds, it means you have cut the dermis layer and damaged blood vessels. The cut really hurts. It hurts because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. Hair follicles are structures where hairs originate. Each hair grows out of a follicle. Hair passes up through the epidermis. It then extends above the skin surface. Oil glands produce an oily substance. The oil is secreted into hair follicles.

Question: "Why is my skin oily?"

Response: "Because the dermis contains oil glands that produce an oily substance"

Peace and Prosperity: After years of government propaganda predicting the worst atrocities, most Japanese civilians were surprised at the warmth and friendliness of the occupying forces. The postwar period began, however, with millions of displaced people homeless and starving. To counter a perceived communist threat from the Soviet Union, the US quickly set to work reconstructing the economy by transforming Japan's institutions and devising a new pacifist constitution. Article 9 renounced Japan's right to maintain armed forces, although the ambiguous wording was later taken to permit the creati on of a "self-defense" force. The zaibatsu conglomerates that had proved so instrumental in boosting Japan's militarism were disbanded, later to re-emerge as the keiretsu trading conglomerates that dominated the economy once again. The entire economy received a massive jump-start with the outbreak of the Korean War, with Japan ironically becoming the chief local supplier for an army it had battled so furiously just a few years earlier. The occupation lasted until 1952, having already planted the seeds for Japan's future stunning economic success. Economic output was back to prewar levels, and British auto companies provided the support needed to get Japan's auto industry back on its feet. Japanese companies then enthusiastically imported any Western technologies they could get their hands on. This included transistor technologyinvented in the US but then considered to have only limited applicationsfor the surreal sum of $25,000. It was Japan that produced the world's first transistor radio. The electronic technology spurt that followed is now legendary. Parliamentary democracy finally came into its own, albeit with distinctly Japanese characteristics reflecting the dislike of debate and confrontation and the group-oriented preference for maintaining the appearance of harmony at all times. The government, through the powerful Finance Ministry and Ministry of International Trade and Industry, generously supported favored private corporations: first shipping, then cars, then electronics firms basked in the warmth of the government's loving attentions. Japan overtook Britain economically in 1964. By the end of the decade, Japan's was the third largest economy in the worldless then two decades after the war had left the country in ruins. Prosperity was not without its own problems: pollution caused by "dirty" industries, a high incidence of stomach ulcers (even suicides) among schoolchildren pressured by over-ambitious parents, and the awkward questions of what to do about nuclear energy. The famous coziness among politicians, bureaucrats, and private companies, together with the strong cultural emphasis on relationship-building and a lack of transparency and accountability, eventually led to corrupt practices of endemic proportions.

Question: "Japan was the third largest economy by the end of which decade?"

Response: "Between 1960-1970"
