As many countries in the world including the Republic of Korea have used all their national resources in the accelerating economic information warfare, illegal leakage of industrial technologies and information has increased rapidly. The costs required for damage prevention from 2007 to 2008 are estimated at approximately KRW 180 trillion which is expected to increase gradually in future. Because the tricks of leaking key technologies are also getting increasingly systematized, sophisticated and bigger, e.g., simple theft at the individual level or the conspiracy of all the staff taking part in the research activities, we should pay special attention to technology security in addition to technology development. While there are several factors affecting such the brain drain, they usually include personal, social, political and cultural factors, for instance, very heavy educational expenditure of children compared to relatively low pay, the speedy labor market circulation for experienced personnel, or political restrictions on researches. In this context, as part of efforts made to prevent the outflow of core personnel, individual companies and research institutes should establish systematically appropriate core personnel management systems for their own organizational or business goals and principles which are intented to ensure to give better treatment and benefit to core personnel and to exercise closer supervision over them. Furthermore, the conventional personnel management system should be radically and flexibly improved in the manner of encouraging the core personnel returning to the organization to combine their external experiences with practices, instead of penalizing them. At the same time, it is necessary to train and educate core personnel through mutual collaboration and in-house training facilities as well as external academic programs operated jointly at the level of the industry. Finally, as the issues concerning the outflow of core personnel are not just problems of relevant companies and other advanced countries have devoted their best efforts to secure their own key technologies at the national level, it is urgent for the industry and the competent authorities to cooperate closely.
For a private toll road project, deciding optimal toll is an important element of economic analysis for the project and a challengeable work. In this study, the optimal toll of a private toll bridge, Geoga Bridge which connects Geoje Island of Gyeongnam Province and Gaduk Island of Busan was estimated using Stated Preference (SP) data. The SP data were collected by interviewing the passenger car drivers travelling on the National Road 14. They are latent users of the bridge. A fuzzy approximate reasoning model to estimate the optimal toll was built using the SP data. For the input variable of the model, the saved travel time and toll level were employed and the diversion rate to the bridge was employed for the output variable. The diversion rates for each toll level and saved travel time were estimated and the toll level which had maximized the toll revenue was decided as optimal toll. The optimal toll was tested by comparing with the average pay rate of passenger car drivers. Since the optimal toll for passenger cars at one hour saving, the 6,250 won is about 50 % of the average pay rate of passenger car divers, the toll was evaluated not to be high. The technique employed in this study may be used for the estimation of the optimal tolls for other kinds of vehicles.

This study evaluated economic value recognized by the residents for the pleasant urban park management using contingent valuation method(CVM) to APEC Memorial Park in Pusan in terms of private fund development for the management of the city park. As a result, the estimated amount payable by each household for the management of APEC Memorial Park in Busan was between 5,673 won and 8,358 won. If such amount is expanded to households in park hosting area, it was 2.2~2.3 times of the park management budget in 2012, which demonstrates the willingness to pay (WTP) of residents for pleasant park was higher than the management budget. Social factors of respondents affecting WTP for city park management operation included age, educational level and income level. Those with high age and high education level had higher WTP. And, WTP was much affected by the use of park and recognition of residents. In particular, those with high frequency in the use of parks had higher WTP, and the users with more than once per week had 1.1 times higher WTP than overall WTP. Then, the satisfaction of park rather than recognition of necessity of park had led to higher WTP. Accordingly, it is necessary to manage park facility management and use program operation to enhance park satisfaction and it is also required to develop a park culture distribution policy to link such recognition to donation.
The purpose of this study is to investigate how certain factors influence job satisfaction and turnover intention of the dietitians working at the correctional institutions. A total 47 sheets of questionnaires (complete enumeration) were distributed respectively to the dietitians during the period from March 20th to May 18th of 2008. A total of 38 questionnaires (response rate 81%) were analyzed by using SPSS (ver. 19.0). The dietitians were more satisfied with coworkers ($3.63{\pm}0.10$) and supervision ($3.19{\pm}0.13$) than with pay ($2.97{\pm}0.09$) and promotion ($2.55{\pm}0.08$). Among the job burnout dimensions, cynicism ($2.58{\pm}0.09$) was rated higher than exhaustion ($2.47{\pm}0.10$), while professional efficacy level ($3.40{\pm}0.08$) was relatively high. The work dimension of job satisfaction was negatively correlated with exhaustion and cynicism dimensions of job burnout (p < 0.001), and turnover intention (p < 0.01), but positively correlated with professional efficacy dimension (p < 0.001). The co-worker dimension was negatively correlated with exhaustion and cynicism (p < 0.05) and turnover intention (p < 0.01), while the supervision, the pay, and the promotion dimension were not correlated with the job burnout and turnover intention. The turnover intention was positively correlated with exhaustion and cynicism dimensions of job burnout (p < 0.001). A stepwise regression analysis revealed that i) professional efficacy was a factor to significantly increase the work dimension of job satisfaction, ii) exhaustion and cynicism to significantly decrease the work and the co-worker dimension of job satisfaction, respectively, and iii) exhaustion to significantly increase turnover intention. The managerial efforts of the institutions could be focused on the job burnout factors to effectively increase the work dimension and the co-worker dimension of the job satisfaction.
The purpose of this study is to investigate how certain factors-especially dietitians' general characteristics and job burnout-influence their job satisfaction and turnover intention. The survey was conducted during the period from September 7th to October 15th of 2006. A total of 91 institutions(response rate 74.6%) was analyzed by using SPSS(windows ver. 14.0). A majority of the respondents were females(97.8%) and 30 years or older(66.0%). Among the job burnout dimensions, exhaustion($2.78{\pm}0.07$) was rated higher than cynicism($2.62{\pm}0.06$), while the professional efficacy level($3.55{\pm}0.05$) was relatively high. The dietitians were more satisfied with co-workers($3.73{\pm}0.07$) and work($3.41{\pm}0.06$) than with pay($2.66{\pm}0.07$) and promotion($2.32{\pm}0.07$). The work dimension of job satisfaction was negatively correlated with exhaustion and cynicism dimensions of job burnout, and turnover intention(p<0.001), but positively correlated with professional efficacy dimension(p<0.001). The supervision dimension was negatively correlated with cynicism(p<0.05) and turnover intention(p<0.001), but positively correlated with professional efficacy dimension(p<0.01). The co-workers dimension was positively correlated with professional efficacy dimension(p<0.01). The pay dimension was negatively correlated with exhaustion(p<0.001) and cynicism(p<0.01) dimensions and turnover intention(p<0.001). The promotion dimension was negatively correlated with cynicism(p<0.01). The turnover intention was positively correlated with exhaustion and cynicism dimensions of job burnout(p<0.001). A hierarchical regression analysis revealed that i) professional efficacy was a factor to significantly increase job satisfaction, ii) cynicism to significantly decrease their job satisfaction, and iii) exhaustion to significantly increase turnover intention.
A project of developing marine environmental risk assesment and management technology was proposed to improve the level of marine environmental management research. This paper attempts to measure the non-market benefits of the project. To this end, the dichotomous choice contingent valuation method is used. In particular, recently proposed one and one-half bounded model is applied. The model can reduce the potential for response bias comparing to the double bounded model while maintaining much of its efficiency. Moreover, in order to deal with zero WTP observations, a spike model is adjusted for our data. A survey of randomly selected 600 households was implemented and the respondents were asked in person-to-person interviews about how they would be willing to pay for implementing the project. Respondents overall accepted the contingent market and were willing to contribute a significant amount (2,663 won), on average, per household per year. The aggregate value of the project in the nation amounts to approximately 46.3 billion won per year. The figure 2.16 of cost-benefit ratio shows that economic validity of this technical development.
This study attempts to apply a conjoint analysis, especially using choice experiment, to quantify the economic benefits of health effects(mortality by lung cancer, asthma, acute bronchitis, chronic bronchitis) on air quality improvement in Seoul and Metropolitan area. The yearly willingness to pay for the highest improvement level which is available is estimated as 38,856 won per household. The aggregated value of Seoul and Metropolitan area is measured as 252.8 billion won annually. The quantitative result provided in this study can be usefully employed in policy-making process related to air pollution. Especially, it provides a methodological framework to estimate the benefits for various alternatives in health effects.

The purpose of this study is to estimate economic value of document delivery services(DDS) at foreign journal supporting center in K University library. For this study, Bass diffusion model, which is widely used in forecasting, especially new product and new service forecasting, was adopted. User survey was also carried out from September 10 to 20, 2007. As a result, useful value(UV) of DDS is estimated about not less than 2,000,000,000 won, and willingness to pay(WTP) is estimated about less than 2,000,000,000 won. This study, economic value analysis at foreign journal supporting center, was limited to DDS, and used methodology for the study is also limited to UV and WTP. Demographic analysis(i.e., sex, age, occupation, educational level) for UV and WTP is also conducted.
In order to investigate the social support and the job satisfaction of the public health nurse, questionnaire survey was carried out on 297 nurses who were working in 25 public health centers in Seoul. The results of the study were as follows; 1. Mean score of job satisfaction was the highest in interaction(3.55) followed by-professional position(3.46), relationship between nurses and doctors(3.23), autonomy(2.85), administration(2.60), requirements(2.43) and pay(2.30) in descending order, and total mean score was 2.92. 2. The level of the job satisfaction was significantly higher in group with longer than 20 years' career and 15 years' in Public Health Center, 5th job rank and income more than two million won a month. 3. The mean score of social support was 3.57 out of 5. The social support tended to be higher in direct social support(3.61) than in indirect social support(3.54). 4. Job satisfaction was significantly correlated with social support(r=0.407). 5. The primary factor which influenced the job satisfaction was the social support which had the 25.5% explaining efficacy. The total explaining efficacy which included pay(6.4%) was 31.0%. In conclusion, it was found out that there existed Pearson's correlation between the job satisfaction and the social support of nurses of Public Health Centers in Seoul. Therefore, what is needed to increase the job satisfaction of nurses of public Health Centers is the politic support for the systems of the social support such as nurse's family, the system of Public Health Center, and the working environment. Finally it is important to increase the job satisfaction of nurses of Public Health Centers through the politic support.
Purpose: We investigated the relationship between professional self-concept and the job satisfaction of physical therapists. Methods: The subjects of the study were 221 physical therapists who worked in medical institutions in Seoul city and Kyounggi do. A questionnaire developed by Arthur and adapted by Sohng and Noh was used for measuring the professional self-concept. A questionnaire developed by Kim and Son and adapted by Kim and Jeon was used for measuring the job satisfaction. Results: The levels of the professional self-concept of physical therapists was a mean of 3.51 points and the level of job satisfaction was a mean of 3.32. There was a statistically significant difference for the professional self-concept of physical therapists according to such general characteristics as age (F=6.38, p<0.05), career (F=4.56, p<0.05) and pay (F=15.94, p<0.05), and there was a significant difference of job satisfaction according to such general characteristics as age (F=15.94, p<0.05), career (F=13.65, p<0.05) and pay (F=12.96, p<0.05). (ED note: this sentence made no sense. What I wrote is guesswork. You have to work on it.) The relationship between professional self-concept and job satisfaction showed a positive correlation (r=0.65, p<0.05). Conclusion: These findings show that modifications to the current program may improve the professional self-concept and job satisfaction of physical therapists.
