Nowadays, a production system has been required to be more flexible, adaptable, and responsive than ever by market dynamics and intense competition. In particular, production systems should be able to dynamically organize and operate production resources in response to environmental changes on their own. This paper proposes a self- organizing mechanism of production resources, based on a dynamically and recursively constructed fractal-like organizational model, named as employment network. Each production resource autonomously makes an employment contract with another production resource and equips aggregated production capability, which incorporates capabilities of its employee resources. In addition, the employment relation is propagated upward or downward in the layered structure of production resources, resulting entire organizational structure. The proposed mechanism can be applied to dynamic production planning issues in terms of matching production resources and production activities. A simulation study to validate the proposed organizing mechanism is also presented in this paper.

A clinical analysis and follow-up study were performed with 35 cases of subarachnoid hemorrhage of unknown etiology among 217 cases of spontaneous subarachnoid hemorrhage who were diagnosed by cerebral pan-angiography and brain C-T scan and treated at department of neurosurgery, Chonju Presbyterian Medical Center from 1977 to 1982. The duration of follow-up study was 6 months to 8 years (mean 4.4 years). The author obtained the following results. 1) Subarachnoid hemorrhage of unknown etiology was 16% of 217 cases of spontaneous hemorrhage. 2) The incidence of subarachnoid hemorrhage of unknown etiology was high in 5th decade and higher in women. 3) Manifestations of subarachnoid hemorrhage of unknown etiology were similar to those of ruptured aneurysm. 4) When primary cerebral pan-angiography was normal, the secondary cerebral pan-angiography was not so meaningful. 5) The overall prognosis of the cases of unknown etiology was good in 30 among 35 cases (86%) who were able to return to their previous occupation. 6) Age and blood pressure were probably major prognostic factor.

Domestic institutions and organizations which keep and manage the important records, historical manuscripts set up the description elements which can figure out their critical information in order to make various users search and utilize them via internet service. And these organizations allow description elements of their own historical manuscripts DB integrated-searched with connection to Korean History On-line. However, their description elements has not been integrated in national level but established with separate ways and Korean History On-line has no independent standard to integrate and manage these description elements. Also, historial manuscripts, which are collected records, have various formats and shapes and their sources information including original locations, publishers, receivers and so on are not known. So, for general users who don"t manage them in the organizations, cannot figure out detailed information easily and accurately and it is necessary to prepare systematic and unified standard for their integrated management. Accordingly, the study aims to review existing standards related to description elements of historical manuscripts and other description elements used differently by each organization"s historical manuscript DB and suggest a standard draft for description elements of historical manuscripts. In order to do so, I analyze three standards of ISAD(G), KORMARC format-Old Books and KORMARC Cataloging Description Rules(draft)-archivesand figured out current status of 4 historical manuscripts managing organizations and their problems on integrated search. Through these reviews, I set up standard draft for description elements of historical manuscripts and applied it to historical manuscripts of 4 managing organizations and check its suitability. Based on this study, if description elements which are differently and separately used by each organizations are unified, the efficiency for not only national level management of historical manuscripts but users" utilization of it will be higher.
