The great flowing of information has brought a necessity for good management to make the best use of it in the highly competitive information age. The aims of this study are to investigate the main information sources - divided into largely three groups: literature sources, communication and information technology facilities), trying to find problem areas associated with IRM, indicating possible solutions. The result shows that internal information sources were regarded the most important and most frequently used. For the use of foreign materials, the higher the level of position is, the more people use them. With respect to communication methods, internal information sources were thought most important. With the dramatic falling of the price despite enormously increased functions, IT facilities are becoming important sources. However, the study reveals the use of them is quite limited to a few well-known facilities, which indicates that management should pay attention to more efficient use of them and useful training and education methods.

In this paper, operations system was designed for the centralization of data processing of various state information from the facilities of mobile communication network. And the system performance experimental system module was measured and analyzed from the designed experimental system module. The configuration of system design was presented with the centralized type to monite and control the facilities of mobile communication network in the central office. The communication process design of the internal system was implemented with the resource of message queue having a excellent transmission ability for processing of a great quantity of information in the inter-process communication among communication resources of UNIX system. The process with a server function from the internal communication processes was constructed with a single server or a double server according to the quantity of operations and implemented with the policy of the presented server. And then, we have measured performance elements in accordance with the change of input parameters from the designed experimental module : response time, waiting time, buffer length, the maximum quantity existing in message queue. And from these results, we have compared and analyzed the system state each server algorithm according to performance variations.

Lychnis wilfordii (Regel) Maxim. is one of the wetland specialists mainly distributed in peatlands at high latitudes. In Korea, it is isolated in two regions. This study investigated habitats, growth traits, and self-compatibility of L. wilfordii and assessed the internal dynamics of its population persistence. Its population has remained stable in the Yongneup Wetland Protected Area (YWPA). There was a clear difference in vegetation environment between YWPA and the distribution area in Daegwallyeong (DWL), Pyeongchang-gun. It has self-compatibility while pollinators facilitate its seed production. It produces a large number of hibernacles and bears the maximum number of branches and fruits in soil with rich organic contents. However, it grows and bears fruits even under the condition of low organic contents. In YWPA, L. wilfordii is not distributed in high moor but widely distributed in low moor where tussocks by Carex thunbergii var. appendiculata are developed. It is mainly distributed on the top of tussocks also. Therefore, it is judged that the formation, growth, and extinction of tussocks by C. thunbergii var. appendiculata is closely related to the establishment, growth, and extinction of plants distributed in this space. It is assessed that the current YWPA has well-developed tussocks in which L. wilfordii is widely distributed, and extinction and re-establishment progress well. Accordingly, the L. wilfordii population is expected to be sustainable in the long term given if its current ecological process is maintained well.

Assessing the effectiveness of R&D organization is hampered by the lack of measurable goals and identifiable outcome criteria. In this review, key issues In evaluating effectiveness are identified and Insights on the application of major assessment approaches are provided. This paper presents System-Process Model on assessing the effectiveness of R&D organization(Korean Government-supported Research Institutes). System-Process Model has attempted to integrate different approaches. It is useful In sensitizing evaluators to the importance of goal, internal process, system resource and feedback in improving organizational effectiveness.

The Purpose of this study was the development of scale to measure the Perceived Adequacy of Resources(PAR). A 38-item instrument was analysed with responses form 300 wives dwelling in Seoul. PAR was categorized housing, health, time money, interpersonal, knowledge/skills, community resources, Data were analysed by the method of Pearson's Correlation, Factor Analysis and Multiple Regression. Items were loaded eight resource categories such as time housing, money , health, knowledge, social support, community, psychological relationship. Internal consistency of the scale was high(Cronbach's α=.85) The result proposed PAR constructed 28 items.

Effect of nine different cations to the formation of iron oxyhydroxide was studied using Mossbauer spectroscopy, XRD and BET. The Redox Potential and pH were measured for the determination of the internal reaction rate, as well. The phases of iron oxyhydroxide could not be the same with each other, due to the present of different cations in solution. Although the oxyhydroxide compound were composed of the same phases, the fraction of each phase was different from each other. The internal reaction rate was varied by the substitution of cation. It could be a cause of the different phase and particle size of oxyhydroxide compound.
