This study reviews and compares four relatively unique and distinct decision support system (DSS) schools or perspectives as follows: Decision Analysis Decision Research Decision Calculus Adaptive Design The purpose of this study is to represent a more constructive approach to the concept of a DSS. All four schools address the development and use of computer-based tools that support and aid managers in their role as decision makers. They differ, however, in terms of the nature of the decision situation, the phase of the decision process, the primary aims for a DSS development, the nature of the learning and the phase of the development process.

This study first searched the theoretical background of programmar productivity related with white coller productivity and carried an empirical study for improving the productivity. In experimental study, productivity was not measured by programming cost but by central processing unit time(qualitative aspects), and it was analyzed by COBOL language and 16 bit personal computer. Also, three file organization method and three access method were selected with this experiment. The experiment was conducted with test data for a programs by individual programming. The result was that relative file is more efficient regardless of updated ratio in file organization and dynamic method of random method is more efficient in file access method in case of 500 updated data, random access method in more efficient in the other cases. Also sequential was more efficient in input in case of 500 updated data, and relative file was efficient in output.

Infiltrating lipoma is a rare mesenchymal neoplasm that, in spite of benign nature, characteristically infiltrates adjacent tissues and tends to recur after surgery. It has a predilection for the extremities and the trunk and is extremely rare in the head and neck region. We present a case of congenital infiltrating lipoma of the face, describing the intrabony invasion and osseous dystrophy as well as the soft tissue changes seen on plain radiographs and magnetic resonance imaging.

This paper attempts to identify critical factors affecting knowledge worker productivity improvement, putting emphasis on the relationships between three kinds of factors (human factors, environmental factors, and managerial factors) and knowledge worker productivity measured by added value productivity and ratio. A field study has been conducted using questionnaire surveys and interviews. Data from the field study are collected from 35 different banking operations in Taegu area and analyzed with analysis of variance.
