  • This study deals with the "Dissemination Stage", the final step in the R&D process consisting of R&DDD($R&D^3$ : Research & Development, Demonstration, Dissemination). At the "Dissemination Stage", the newly configured technical design is compared with other alternatives to come up with the most desirable selection. The assessment conducted at this stage is not a simple procedure. It goes through the complex evaluation process in which various elements including economic effects and technical characteristics are considered. The reason for taking such a complex procedure is that the assessment, selection and application of the desirable technical alternative is critical for the company's competitive edge in every field of industrial sectors, thus influencing its survival and continuous growth. This study reviews the AHP method for assessing technical alternatives of the heat supply system design. And, to show the practical validity of the AHP method, it is applied to the evaluation of waste heat system alternatives in the field of energy supply system technology.

  • This study focuses on the emergence of collective intelligence and its impact on the democracy in the information era. Scholars have posed very different-optimistic and pessimistic-views on the possibility of collective knowledge produced by the public. Focusing on the cases of a free online encylopedia known as wikipedia and 2008 Candlelight Demonstration against the imports of US beef in Korea, this paper analyzes the mechanism of collective intelligence and its political implications on the democracy. Specifically, this article approaches changes in new knowledge paradigm with two different variables: the degree of connectivity and the quality of deliberation. Applying two different sets of variables helps us to distinguish the possibilities of collective intelligence and anti-intelligence, which would suggest social and political implications for the democracy in a country. This study finds a critical difference in terms of the quality of deliberation, measured by the indicators such as diversity, independence, and integration mechanism for online deliberation.

  • This study was designed to analyse effects of Family Health Workers' activities on the performance of a child immunization program as part of the evaluative research in the community health demonstration project in Kang Wha. Frequent shortcomings of evaluative research are problems in setting evaluative indices, difficulties in interpreting influences of socioeconomic changes due to lack of control and failure of demonstrating association between activity input and program performance. Specific objectives of this study was to improve the frequent shortcoming of evaluative research by isolating the effects of Family Health Workers' activities on the performance of the program through controlling other variables which also influenced the program performance. The target population consisted of 1240 children who were born between Jan. 1971 and Dec. 1975 in Sunwon Myun, and Naega Myun in Kwang Wha Gun, Kyonggi Province. The data were collected in part through 20 Family Health Workers who interviewed the mothers of these children in their villages during Nov. 1977. Part of the data were obtained by summarizing Family Health Workers daily activity records. All data were grouped for each birth cohort according to the 20 villages. Dependent variable of the model is the measle immuinization rate of each village and the independent variables are characteristics of baby, mother, household, travel time to the health subcenter, to Kang Wha Town, and the mean member of visits to the household by Family Health Workers as well as their other related activities and the year of birth of children according to village. The model was analysed by stepwise multiple regression technique. The summarized results show that overall $R^2$ were 39.3% and mean number of Family Health Worker household visits, mean age of mother and mean economic status were significant variables in explaining the immunization rate. Therefore Family Health Workers' activities are one of the significant variables in influencing the increased immunization rate of children in villages of the project area.

  • Managed aquifer recharge (MAR) is a promising water management strategy for securing stable water resources to overcome water shortage and water quality deterioration caused by global environmental changes. A MAR demonstration site was selected at Imgok-ri, Sangju-si, Korea, based on screening for the frequency of drought events and local water supply situations. The abundant groundwater discharging from a nearby abandoned coal mine is one of the potential recharge water sources for the MAR implementation. However, it has elevated levels of arsenic (~12 ㎍/L). In this study, the potential of the natural attenuation of arsenic by the field geological media was investigated using batch and column experiments. The adsorption and desorption parameters were obtained for two drill core samples (GM1; 21.8~22.8 m and GM2; 26.0~27.8 m depth) recovered from the potentially water-conducting fracture-zones in the injection well. The effluent arsenic concentrations were monitored during the continuous flow of the mine drainage water through the columns packed with the core samples. GM2 removed about 60% of arsenic in the influent (0.1 mg-As/L) while GM1 removed about 20%. The results suggest that natural attenuation is an acitive process occurring during the MAR operation, potentially lowering the arsenic level in the mine drainage water below the regulatory standard for drinking water. This study hence demonstrates that using the mine drainage water as the recharge water source is a viable option at the MAR demonstration site.

  • The Government is going to enforce assessment of dental institutions in addition to assessment of medical institutions so that it can provide good-quality medical service to people having much interest in quality of medical service. But the empirical research on the assessment of dental institutions which is still in a model assessment stage, is insufficient. Accordingly, the present research aims to help dental institutions preparing the main assessment by researching an acceptance level of workers of dental institutions in a process performing assessment of dental institutions, based on the preceding researches that the perceived utility has influence on implementation intention. The present research proved the influence that job relevance, result demonstration, usability and education & training of workers and manager's leadership of an infection management part affects perceived utility and implementation intention. As a research result, all the job relevance, result demonstration, usability have a positive(+) influence on perceived utility and implementation intention, and the influence of job relevance most affects especially. The leadership and education & training have influence on what workers get to have implementation intention after perception of utility of infection management according to the order. According to the above results, it can be understood that medical institutions preparing for assessment of dental institutions take charge of the assessment part having high relevance with work of workers and need to make a manager ordering performance of its assessment be able to foster a leadership for improving effectiveness of assessment performance.

  • The contaminated soils near abandoned mine area can threaten human's health and natural ecosystems through multiple pathways. Remediation of contaminated soil using physicochemical technologies are expensive and destructive of soil environments. On the other hand, environmentally friendly approach that maximize biological remediation, that is, phytoremediation, attracts attention as a low carbon green growth technology. This research is a field demonstration study, focused on the enhanced phytoremediation by bioaugmenting PGPR(Plant Growth Promoting Rhizobacteria)that is helpful on the growth of and heavy metal removal by Echinochloa frumentacea, at a Zn contaminated paddy soil near SamBo mine at Hwasung, Kyunggi. The results showed that the zinc removal by the plant with PSM(Phosphate Solubilizing Bacteria), a kind of PGPR, was three times higher than that by the control. The results are valuable as it is a result from the field-scale technology demonstration. The results also implies that application of PGPR can enhance heavy metal removal from contaminated soil in full scale phytoremediation using Echinochloa frumentacea.
