  • Current fire safety in the construction sites has developed piecemeal over a considerable period of time. However, the law and regulation of fire safety is insufficient to protect fro in the construction sites. The frequency of fire in the construction sites is very rare but it brings longterm deterioration durability of building structure and large scale industrial calamity. There are many process of works and each work deals with many kind of flammable material, so it is very difficult to find a proper safety fire prevention. This study executed the questionnaire and fire experiment of the welding work to provide effective fire prevention counterplan.

  • High-speed machining is a very useful tool and one of the most effective rapid manufacturing processes. This study sought to produce various high-speed machining materials with excellent quality and dimensional accuracy. However, high-speed machining is not suitable for microscale thin-walled structures because the structure stiffness lacks the ability to resist the cutting force. This paper proposes a new method that is able to rapidly produce very thin-walled structures. This method consists of high-speed machining followed by filling. A strong work-holding force results from the solidification of the filling materials. Low-melting point metal alloys are used to minimize the thermal effects during phase changes and to hold the arbitrarily shaped thin-walled structures quickly during the high-speed machining. We demonstrate some applications, such as thin-walled cylinders and hemispherical shells, to verify the usefulness of this method and compare the analyzed dimensional accuracy of typical parts of the structures.

  • Purpose - This study attempted to identify any influencing relationships, between the antecedent variables and the members' innovative work behavior, which were expected to influence organizational performance based on the extended theory of planned behavior (ETPB). Research design, data, and methodology - The survey was conducted on SMEs in Seoul and its metropolitan area. A total of 158 copies of effective questionnaires were used and were analyzed through correlation analysis, regression analysis, and multiple regression. Results - Self-efficacy, value, intrinsic motivation, and self-enhancing bias have been found to have a positive relationship with innovative work behavior. In addition, transformational leadership was found to moderate the existence of a statistically significant negative influence between value, intrinsic motivation, and innovative work behavior. Conclusions - The results suggest that leaders will be successful in winning members' trust through conducting their behaviors in accordance with the applicable ethical and moral standards and through their fair, transparent, and legitimate management practices with an attitude of 'taking the initiative and setting an example', and this will help solve such problems.

  • The specialty of Construction Manager's work is largely depends on the project progress stage and the type of management work. However, at present, career management system manages only the type and duration of the construction project, disregarding specialty and competence. However, in order to select a right construction manager for the client's needs or project characteristics, career management should be subdivided and managed according to the project progress stages or the types of management. In addition, this career management plan is essential for construction managers to receive appropriate wages for their careers and competences. Therefore, this study proposes a classification system for the integration of career, work, and competency to promote effective career management.

  • For the perfect cure of rheumatoid arthritis, the ultimate hope of patients and therapist, it is necessary to find a patient early and treat him properly and to teach him what rheumatoid arthritis is. 1. Although rheumatoid arthritis is a chronic disease and its cause is uncertain matke the patient understand that there are many ways to reduce symptoms and to prevent deformation. 2. Explain the peculiarity and the procedure of rheumatoid arthritis to the patient and encourage him. 3. Teach the patient how to protect his arthrosises by showing him concrete movement. 4. Teach the patient or his family the ways to relieve rheumatoid arthritis easily in his house for continuous remedy. In order to make that remedy most effective for the patient, a complex and balanced treatment, considering medication, surgical teatment and rehabilitative treatment, has to be applied, which needs team work. Team work occurs when doctors, physiotherapists, nurses, nutritionists, clinical psychologists, prosthesis manufacturers, social workers, employment agents and the family of the patient work together. The members of the tern have to onderstand the procedure of the treatment of rheumatoid arthritis and apply proper remedies according to the condition of the patient.

  • Retaining wall is a constructed structure in order to construct road, rail, building for effective use and obtainments of the limited ground. Recently, many kinds of research have been actively developed for a standardization and information to the maintenance and management of bridge, tunnel, road. With the works of database construction of that, many kinds of data with respect to statistics is cumulated. Database work of retaining wall is wholly lacking and lagged behind in the works of database construction. This paper suggests classification system on inspection data. On the basis of that, code work with classification system was practised and DB program of inspection data of retaining wall was developed. And input work for a data of maintenance and management was practised. The purpose of this paper is to suggest a kind of statistics data and investigate a characteristics of inspection using statistic data on retaining wall.

  • This thesis deals with the method of Work Sampling to compare production activity due to change of productivity, workmen's productivity environment, nonproductivity of machine and plant when there is a process before and after change of work environments. So, this study takes $x^2$ - test to discover significant change of process, and obtains Proper observation number due to ratio difference-test over change of productivity before and after process change. Therefore, this thesis represent statistically effective results between two periods before and after process change.

  • This study examines work and family life of married women and policy implications of the low class in Daegu area. Data were gathered from the use of face-to-face interview method from a sample of 564 married working women. And the political printed materials of family welfare policy(1988~1993) were analyzed. The major findings of this study can be summarized as follows: Most of the respondents remain unstable in their working situation with the double burden of a paid work and housework. Thus it is necessary for the government to implement family policies for married working women such as establichment of various child care centers study room for adolescence councelling center job-training center and dissemination of egalitarian sex-role attitudes. Finally it is suggested that the formulation of family net works be promoted for the effective utilization of local resources and family welfare programs.

  • It was studied in the present work how the thermal cycling performance of LOC (lead on chip) packages depends on the package construct or leadframe materials. First, package body thickness and Au wire diameter were manipulated for the selection of proper package design. Secondly, two different types of leadframe materials (i.e. copper and 52%Fe-48%Ni alloy) were tested to determine the better material for improved reliability margin of plastically encapsulated microelectronic packages. This work shows that manipulating package body thickness was more effective than an increase of Au wire from 23$\mu\textrm{m}$ to 33$\mu\textrm{m}$ for the prevention of wire debonding failure. Further, this work indicates that the LOC packages including the copper leadframes can be more susceptible to thermal cycling reliability degradation due to chip cracking than those including the alloy leadframes.
