This study reviewed the national standards for risk management to judge whether they are suitable for a product safety management program. Among the standards issued from Australia, New Zealand, Canada, Japan, and UK, the risk management guideline (AS/NZS 4360: 2000) issued jointly from both Australia and New Zealand have better features of product safety management program such as a broad definition of risk concept including opportunities of loss and gain, stepwise composition of processes applicable iteratively, and integrable composition of processes for the existing other management practice. Comparing the three product safety management programs suggested by several authors yielded common features of product safety management program model: (1) organization for product safety, (2) risk identification, (3) risk evaluation, (4) risk treatment, (5) monitoring/communication, and (6) documentation. All of these activities can be performed within risk management framework.

Personal NO$_{2}$ expousre and time activity patterns were measured during March, 1991 for 46 taxi drivers in the Seoul area. Badge-type personal samplers were worn for 24 hours by taxidrivers for monitoring personal expousre to NO$_{2}$. A standard respiratory questionnaire was administered and pulmonary function test was performed using a protable spirometry. The mean concentrations of personal NO$_{2}$ expousres of taxi drivers were 0.55ppm. Personal NO$_{2}$ exposures of taxi drivers were seemed to be higher in longer period of driving, smokers, and use of LP gas in homes. Prevalence rate of respiratory symptoms and the level of pulmonary function(FEV$_{1.0}$ and FVC) seemed to be related to higher personal NO$_{2}$ concentrations. It is concluded that persoanl NO$_{2}$ expousres of taxi drivers are probably affected by indoor NO$_{2}$ levels of a tax/and their common activities.

In current complex nature of management with task-structures, a method to reach the enterprise's informationalization success is not common. To satisfy these various requirement, improving the usability of information technology (IT) is a key factor which defining the level of organizational requirement first. Imposing an IT-solution which has excess service of the organization's previous task-environment, procedure and scope is not effective to SME-level unit, which unit could not have a formal organization structure and task structure. SME level informationalization will be success if each function realizes easier on the task-employee's viewpoint. Achieving this objective, a solution provider or department must reflect their work characteristics of nature which has least level of work performing resistance. It is most useful system for SME level unit, if a provider develops single programs which based on task activities, and each program can configure network-linking.

Data sharing is a major challenge to implement CALS. STEP is the international standard for the product model data exchange among heterogeneous systems and plays a key role in CALS. Advances in computer networks are rapidly changing the product development processes. The network oriented modeling system premises to integrate design activities across the enterprise. To achieve goals of CALS 3-dimensional concurrent modeling that complies international standard is required since integrity and common perception of product data can be assured. This paper presents 3-dimensional concurrent geometric modeling on high speed network using STEP and methodologies.

Most important of all was the concept of library life-long education on which the studies were to be based. This concept has been broad, both in its interpretation of what constitutes a "program" and of what life-long education in a library is. No formal definition was adopted, but a common understanding existed that a fundamental purpose of the public library is to provide the means of continuing education, and to encourage the most effective utilization of these means through a program of activities whose effects are continuous and cumulatives. There are educational program, socio-cultural program and recreational program in the life-long education program of the public library. These programs can be planned by which the public library developed its resources and its services. services.

The color planning in the hospital could influence the patient's improvement and lead the users from room to room. This study shows the data of present colors used in the hospitals. In order to get the data, we surveyed and analyzed the current color usages of the present interior of hospitals by the individual data from the projectors. The color scheme is analyzed by the rooms which are the common room, the ward, and the examination room along the projectors. It is also analyzed by the finishes of the hospitals, and is addressed to the present color scheme by the means of the hue value, and chroma. The color scheme in the interior design of hospital is an important factor for the hospital users. It has to more sincerely considered to use colors effectively in the hospital interior since people use their organ of vision greatly when they sense things. According to the data, this study is proposed to the effective color plan which is considered psychologically and emotionally about the human activities, in the interior design of hospitals for the future.

For the risk analysis and risk assessment techniques to be effectively applied to the field of information technology (IT) security, it is necessary that the required activities and specific techniques to be applied and their order of applications are to be determined through a proper risk management model. If the adopted risk management model does not match with the characteristics of host organization, an inefficient management of security would be resulted. In this paper, a risk management model which can be well adapted to Korean domestic IT environments is proposed for an efficient security management of IT. The structure and flow of the existing IT-related risk management models are compared and analysed, and their common and/or strong characteristics are extracted and incorporated in the proposed model in the light of typical threat types observed in Korean IT environments.

Cissus quadrangularis L. variant I (Family: Vitaceae), the common variant with square stem is widely used for peptic ulcer disorders (PUD) in traditional medicine. Aerial parts were collected during flowering and vegetative seasons and analysed. Aqueous (hot and cold) and solvent extracts (acetone, chloroform and ethanol) were screened for their anti-Helicobacter pylori (Hp) activities. Among them chloroform extract was observed to recover bioactive principles markedly with low minimal inhibitory concentration (MIC) and minimal lethal concentration (MLC). MIC was $30\;{\mu}g$ in both samples and MLC was $35\;{\mu}g$ for vegetative and $30\;{\mu}g$ for flowering seasons, respectively. Extracts from samples collected during flowering season were better than thse of vegetative season.
