Stone Industry in our country is classified mainly in view of supply of raw materials ingredients, as follows: Stone-Quarrying Industry who develops the natural resources, Stone Processing Industry who processes the quarried raw ore into construction materials and stone-products, Stony Mountain-Aggregate Industry who supplies the elementary raw materials ingredients to construction section, respectively. Among them, while Stone Processing Industry sells its turnover around billion-Won level per annum per a company, most of other job sites are paltry, adopting less than 10 employees, and it is real state that their working environments are also very coarse. The Noise originated from processing-instrument which generates at such Stone Processing Industry is as so repeatedly reiterating Loud Noise that most of the spot workers are forcedly imposing such dangers as the severe unpleasant feeling and hearing impairments. On this viewpoint, this Research is now analyzing on the frequency characteristics with regard to the Noise that generated from various processing-instruments, and then based on this, in order to grasp the influence of the Loud Noise generating when process the stone materials, this study has ever evaluated it with PSIL and NR. It is considered that such data could be used as the valuable material for establishment of a comfortable working environment hereafter.

The waterproofing system's performance is known to show a determining by complex interaction of material factors, design details, and the qualify of construction, and the waterproofing integrity of waterproofing membranes is determined by the bond to the deck and the amount of damage to the waterproofing membrane. In this research, the basic properties of waterproofing membranes on market and the tensile adhesive characteristics of waterproofing systems of concrete bridge deck have also been investigated in the view of the damages frequently reported from job site. As a results of tensile adhesive strength of waterproofing system, tensile strength is decrease with surface moisture contents except for inorganic-elastomeric liquid waterproofing membrane, and increase with strength of deck slab. Also tensile adhesive strength is generally increase in case of moisture curing of specimen because of pore structure and surface leveling. The after asphalt concrete paving tends to increase more than before those. The results of the liquid waterproofing membranes are upside-down, and the more concrete has strength, the more strength of tensile adhesive increase. The ambient temperature and the rolling temperature of asphalt concrete when application of the waterproofing membrane has considerable influence on the performance of waterproofing system.

In order to obtain basic information for the extablishment of effectivce industrial safety programmes in heavy industries & construction companies, accident records for 366 injured workes were collected from January, 1989 to December 1991 and analyzed. The results were as follows : 1. The over-all incidence rate of industrial accidents was 2.98% per year 2. Accidents were common in the workers who are in thirties and twenties. 3. According to the duration of services, the workers with jobs on above than 3 years was the most frequent victims (64.2%) 4. According to the view point of working time, the highest incidence was observed just before the end of the work (17:00-19:00). 5. According to the month of year, the incidence was higher in August(14.0%) and May(14.2%), and lowest in January (3.3%) 6. The most common type of accidents was overexertion (24.9%). 7. According to the job, the highest incidence was observed fabrication. 8. According to the site of injuries, the incidence was higher the truck (27.0%) and fingers (25.1%).

The survey was conducted on 16 questions for 24 professions, 20 questions for 250 students following school such as Pusan National school of nursing, Maryknoll school of nursing, Boak oum school of nursing, Chun hae school of noising if Pusan from April 17. to September 15. 1971. The results of the evaluated were follows: It was found that the most of students are majoring nursing, the reasons are 1. For future home life (21%) 2. For secure job(16%) The feeling of clinical practice. 1, Expected too much (32%) 2. Unstabled(36.4%) 3. Fearful(31.6%) The main problems which student nurses. 1. The gap between lecture and clinical practice (22%) 2. Over clinical practice(18%) 3. Unfairness of evaluation practice (66.5%) As matter of fact. it was revealed that the professor's adequate clinical supervision was mainly attributed to the professor's excess workload consisting of lectures, and other duties. Professors and they also recognised that appraisement of clinical experiences of students are often found to be biased. In view of the findings of this study regarding the educational process and its principles of formation above, a few suggestions have teen made regarding the development of the Curriculum of nursing school in Pusan.

This study show the improvement of the capability of the handling computer in the job to students in science of nursing though the investment of the capacity of the computer application and the realities of handling computer in real. A cause of the development of the Information Technology, currently in the view point of system management, the hospital works is manage by the HIS(Hospital Information System). The teaching of the computer application capability for the information in science of nursing must not be the one-way by supplier like one of the survey courses but must be adapted at real condition and to be focused to learner. Thus, we suggest that the education of the science of nursing should be changed from one of the survey courses to the education of the acquirement and experience on information system knowledge.

This study is about projection methods in computer games that support graphic user interface. Most of previous studies were case studies on or aesthetic approaches to a specific projection method. We investigated projection methods observed in computer games according to the chronicle of games, and studied changes in the methods and their future direction. Furthermore, we examined the emotional and productive aspects of various projection methods, and found that projection methods in computer games are being developed in accordance with graphic designers' job difficulty and computer processing capacity. Project, which determines contents consumers' view, is a very important factor to be decided at the planning stage of contents development. In this sense, we expect the results of this study to make a contribution to relevant areas.

The change of job environments with information technologies demands workers' capabilities to adapt rapidly changing and variety of work environments. To cope with this situation, many countries and institutions propose 'basic vocational competency' which is focused on basic capabilities of workers. And also, they do research on how to educate and train students to be prepared for new environments. We surveyed with teachers of computer technology which is one of the information technologies, to find out the competency development level, they expressed negative view on general competency development because of current computer education's focusing on 'using computers to process information'. Therefore, we intended to analyze the necessity and problem of developing the whole basic vocational competency in vocational high school and proposed a 'in context' learning for it.

The real time scheduling is a key research area in high performance computing and has been a source of challenging problems. A periodic task is an infinite sequence of task instance where each job of a task comes in a regular period. The RMS (Rate Monotonic Scheduling) algorithm has the advantage of a strong theoretical foundation and holds out the promise of reducing the need for exhaustive testing of the scheduling. Many real-time systems built in the past based their scheduling on the Cyclic Executive Model because it produces predictable schedules which facilitate exhaustive testing. In this work we propose hybrid scheduling method which combines features of both of these scheduling algorithms. The original rate monotonic scheduling algorithm didn't consider the uniform sampling tasks in the real time systems. We have enumerated some issues when the RMS is applied to our hybrid scheduling method. We found the scheduling bound for the hard real-time systems which include the uniform sampling tasks. The suggested hybrid scheduling algorithm turns out to have some advantages from the point of view of the real time system designer, and is particularly useful in the context of large critical systems. Our algorithm can be useful for real time system designer who must guarantee the hard real time tasks.

This paper aims to propose a framework of content creating group with creativity under new convergence environments. The framework is built based on content concept hierarchy(deep/surface) relating with the creativity of group members. The diversity of group members(potential creativity) decrease and change into creative abilities in one unified view at each content concept hierarchy in time. To do this, three methods of building a creative group(interaction-base, direction-base, hybrid) are proposed. Cooperating processes and operators are designed to promote creative abilities in the content producing group. These cooperations are considering new media convergence industry's job road map(IPTV) and fundamental content attributes(semantic, narrative, discourse). In the framework, creative content is produced with the help of member's cultural openness, media richness and synchronicity, hierachical adaptability on dissimilarity. Deep level creativity of cognitive semiotics on moving image content is composed of psychological, transformational, situational creating abilities in the structure of group members. Designing analogy, metaphor, symbol operators help members to traverse deep structure of content concept hierarchy. Our framework has strong points to relate fundamental content deep structure with structure of content producing group and to induce creativity on cognitive structure of human being.

Everyone lives in a home. We pursue happiness and the meaning of life through home life or family life. Home life, therefore, has an important meaning in the whole life, But home life can be sustained only through housework and wage labor. All human activities can be divided into two kinds of activities. The one has intrinsic value, the other has extrinsic value. Housework belongs to the activity with intrinsic value, but wage labor belongs to the activity with extrinsic value. In view of home life, housework has primary meaning, and wage labor has subsidiary meaning. In other words, wage labor is only means of home life. We mush not forget that important fact. But we cannot help thinking that nowadays people consider wage labor itself as an aim of life. It is said that we are achieving self-actualization through wage labor, but it is not ture. To tell the truth, most of us are experiencing self-alienation in job. We must recover the legitimate relation between housework and wage labor. Wage labor is means of home life, therefore it is on the extension line of housework. If we achieve happiness through home life, we must recognize that wage labor is only means of home life, not an end in itself.
