  • Philodromidae Thorell, 1869 is one of the most diversified and largest families comprising 522 species in 29 genera within the order Araneae Clerck, 1757. The genus Thanatus C. L. Koch, 1837 comprise 99 species of the family and four species of the genus Thanatus (Philodromidae) have been recorded in Korea: T. coreanus Paik, 1979, T. miniaceus Simon, 1880, T. nipponicus Yaginuma, 1969, and T. vulgaris Simon, 1870. Two females of T. arcticus Thorell, 1872 were collected by sweep net between the shrubs in mountainous mixed forests from Mt. Chiaksan National Park, Wonju-si, Gangwon-do and Mt. Naejangsan National Park, Jangseong-gun, Jeollanam-do. The present study describes T. arcticus with measurements and taxonomic illustrations.

  • The Equilibrium Theory is one of the key theories on the study of maintenance and continuance of organization. A contributor or participant of the business organization has been given the needed incucements and motivated to join in business. To keep this situation balanced is, so-called, the organization equilibrium. C. I. Barnard was the first to research this, and that J. G. March and H. A. Simon advanced it. Modern organization theory is not only the equilibrium theory but continuance theory of organization. That is, the continuance of business administration organization relies on the willingness to cooperate with which the participants in business try to devote themselves to business. The organization itself is not only combined with its members and assets but a kind of behaviour system which every member makes an effort to contribute. On a view of dynamics, organization remains, prospers and deceases in process of its formation, disorganization and reformation. But taking consideration into going concern, it is necessary that we should plan to strike a balance of business administration organization. We can write down the proposition of this theory as follows: The continuance and growth of organization=inducements contribution The basic idea of this theory was established by C. I. Barnard. But it implied many problems such as incorrect statistical measures and the defects of objectivity. These problems were more or less rearranged and improved by so-called March-Simon's equilibrium theory. Especially March-Simon's general models of organization equilibrium are a great success in this field. In the future, these problems mentioned above will be a challenge to workers in this field how we shall diminish the defects to the minimum and how perfectly we can progress it.
