The Korean government had introduced the industrial safety & hygiene consultant(ISHC) system to improve worksite health and safety level by providing specialized industrial safety & hygiene(S&H) services in 1996. Despite of initial hopeful expectation it has been said that this plan might fail to settled down and maintain its purpose. This study was designed to investigate operational issues and problems concerning the ISHC system, that would direct the way of change and future role. Questionnaire were sent to ISHC, professional engineer, agencies for occupational injury prevention, S&H specialist in the corporation nationwide and totally 256 people responded to in having 62.7% of response rate. The result of this study were as follows; 1. One hundred and forty two cases of safety assessment and 27 cases of process safety reports were the six years' results since 1996 the ISHC program had first been introduced. This results showed that injury prevention activities of ISHC had been stagnant. 2. The 78.8% of respondents had negative opinion about injury prevention activities of ISHC program. 3. The operational problems of ISHC were lack of understanding of company about ISHC, low systematization of work items, duty overlapping with agencies for occupational injury prevention, low support by government. in order. 4. It was suggested that abolition of ISHC and promotion of professional engineer system should be considered. 5. To promote professional engineer system it was suggested that the professional engineer could conduct consulting service and ISHC should be integrated with the expert system.

This study analyzes the impact of digital strategy on firm performance through relational behavior, cognitive dimensions, and continuous digital transformation based on social capital theory. The research model was tested using data collected from a survey of 300 domestic corporate employees who have worked for over a year, conducted from February 20 to 23, 2024, using Smart PLS 4.0. The key findings of the study are as follows: First, it was confirmed that digital strategy plays a crucial role in promoting cooperation and interaction within the organization, enhancing members' understanding and perception of digital technology, and strengthening the firm's competitiveness through continuous change and innovation. Second, continuous digital transformation and cognitive dimensions positively impact firm performance, while the influence of relational behavior dimensions was found to be insignificant. These findings suggest that digital strategy can significantly affect firm performance by fostering interaction and perception changes within the organization, beyond mere technology adoption, and provide strategic implications for Korean firms to effectively pursue digital transformation.

The purpose of this study was to survey the hospital staff's perception of hospice and death and thereby, suggest the ways to help them have a mature attitude towards and a better understanding of death through an effective education on hospice. For this purpose, this study was designed to provide some data useful for the hospital staff not experienced in facing the dying patients to handle the desperate situation skillfully and engage themselves more effectively in their hospice services. For this study, the researcher conducted a questionnaire survey for the staff of 'C' hospital in Seoul about their hospice philosophy, attitudes towards hospice and perception of death for the period from February, 2006 to March, 2006. A total of 751 subjects responded effectively to the survey. The data collected were analyzed using the SF55 11.0 for ANOVA and T-test in order to test the relationships among subjects' perception of death, their demographic variables, their health condition, their hospice philosophy formed from their experiences of patients' death and hospice services and their attitudes towards hospice. Besides, the correlations among their hospice philosophy, perception of death and attitudes towards hospice were tested. The results of this study can be summarized as follows; First, as a result of testing the relationships among subjects' experiences of health consulting. their experiences of patients' death and hospice and their hospice philosophy, it was confirmed that their experiences of health and death consulting and their experiences of having been educated were relevant. Second, it was found that such variables as health condition, death, experience of hospice and attitude towards hospice were not significantly correlated with each other. Third, as a consequence of testing the relationships among health condition, death, experience of hospice and perception of death, it was disclosed that only the physical health condition was significant. Fourth, it was confirmed that subjects' hospice philosophy, perception of death and attitudes towards hospice were at the usual level on average. Fifth, hospice philosophy, perception of death and attitudes towards hospice were found correlated significantly with each other. Sixth, as a result of the stepwise variable adjustment for such variables as hospice philosophy, perception of death, attitudes towards hospice, it was found that the adjusted r-square value was 0.347 when departments, experience of having been requested by dying patient for consulting, experience of having been educated on hospice, religion and marital status were set as independent variables. And the estimated value of each variable was found significant. Seventh, as a consequence of conducting the multiple regression analysis by setting 'religion' as significant independent variable, it was found that the estimated value of physical health condition was not significant statistically. This, as a result of the simple regression analysis for 'religion' only, its explanatory power was found .197, while its adjusted r-square value was 0.20. Eight, it was found that subjects' attitude towards hospice was significantly correlated with such variables of experience of patient's or relative's death, experience of having been requested for consulting about death, gender, marital status and departments. As a result of the multiple regression analysis and the subsequent stepwise adjustment for this variable, it was found that only 'experience of having been requested for consulting' had some explanatory power: its adjusted r-square value was 0.089. As discussed above, this study tested the correlations among various variables including hospital staff's attitude towards hospice and perception of death and thereby, provided for the data useful for their education on hospice. This study may be significant in that it proved that it would be essential to educate hospital staff on hospice for more effective care of hospice patients and their family members at hospital.

This study is focused that the electronic commerce(EC) on the purchasing section may improve the efficiency and transparency of the hospitals management. After reviewing the purchasing activity of hospitals, I study the introduction, expected effects, and problems of EC. So, I am going to provide basic information for activating EC. The samples are managers of 170 hospitals, which are located on Seoul. As a result of collection this survey, I analyze 79 hospitals. For data analysis, I use $X^2$-test and ANOVA for purchasing management and the relevance of EC according to the level of care. The results of this study are 1. The problems on the management of purchasing section are: firstly, they don't have sufficient time to study market. Secondly, it is difficult to find competitive suppliers. And, lastly, they cannot gather a lot of information about the price of products. 2. There are many answers of the needs on the introduction of B2B. However, some hospitals think they don't need it. But, the most answers are that the EC will be settled within 4 years. So, we can realize that these hospitals are getting interested on the EC. On the other hand, I find that they prefer outside EC companies for the introduction of EC. 3. On the expected effects on EC, first is the effectiveness of the market survey. The next is to collect information of adequate price of products owing to clear transaction, find easier new suppliers and gather useful data. 4. On the external problems of the introduction of EC, there is low credibility related to the security and the weakness of suppliers' information system. Especially, on the Real Transaction Price Payment system, the bigger bed size, the higher understanding on these problems. On the internal problems of the introduction of EC, first is the burden of the introduction of EC and operating cost. Especially, on the burden of the disclosure of revenue source, the smaller bed size, the higher understanding on this problem So, this is a point which deserves my attention statistically. However, this shows relatively little understanding about incomplete the standard of product category and the weak information system of hospital. Through this study, I am going to suggest 3 points for the activation of the introduction of EC on hospitals. 1. The reform of the Real Transaction Price Payment System on medical supplies and materials for medical treatment 2. The establishment of the standard of product category 3. The promotion of information system based on network.

An artificially modulated magnetic Co/Pd multilayer is one of the promising candidates for high density magneto-optic (MO) recording media in the wavelength of a blue laser beam, due to large Kerr rotation angle. However, since the Co/Pd multilayer is a non-equilibrium state in terms of free energy and MO recording is a kind of thermal recording which is conducted around Curie temperature (Tc) of the recording media, the assessment of the thermal stability in the Co/Pd multilayer is crucially important both for basic research and applications. As the parameter of the thermal stability in this research, effective interdiffusion coefficients (Deff) perpendicular to the interface of the Co/Pd multilayers are measured in terms of Ar sputtering pressure and heat treatment temperature. From the results of the research, we find out that the magnetic exchange energy between Co and Pd sublayers strongly affects Deff of the Co/Pd multilayers. This discovery will provide the understanding of the magnetic exchange energy in the effective interdiffusion process of a magnetic multilayer structure and suggest the operating temperature range for MO recording in the Co/Pd multilayer for the basic research and applications, respectively.

An artificially modulated magnetic Co/Pd multilayer is one of the promising candidates for high density magneto-optic (MO) recording media, due to a large Kerr rotation angle in the wavelength of a blue laser beam. However, since multilayer structure, as well as amorphous structure, is a non-equilibrium state in terms of free energy and a MO recording technology is a kind of thermal recording which is conducted around Curie temperature (Tc) of the recording media, when the Co/Pd mulilayer is used for the MO recording media, changes in the magnetic properties are occurred as the amorphous structure do. Therefore, the assessment of the magnetic properties in the Co/Pd multilayer during interdiffusion is crucially important both for basic research and applications. As the parameter of the magnetic properties in this research, saturation magnetization and perpendicular magnetic anisotropy energy of the Co/Pd multilayer are measured in terms of Ar sputtering pressure and heat treatment temperature. Form the results of the research, we find out that the magnetic exchange energy between Co and Pd sublayers strongly affects the changes in the magnetic properties of the Co/Pd multilayers during the interdiffusion in ferromagnetic state. This discovery will provide the understanding of the magnetic exchange energy in the Co/Pd multilayer structure and suggest the operating temperature range for MO recording in the Co/Pd multilayer for the basic research and applications, respectively.
