  • The object of this study was to develop an economic assessment program for the optimal design of the cogeneration systems composed of combining engine, generator, waste heat recovery exchanger, absorption chiller, and boiler, etc. The energy demand categorized by electric power, heating, cooling and water supply was determined by statistical data of the existing cogeneration systems. An economic assessment was performed by comparing the total cost of cogeneration system with that of non-cogeneration system. The total cost was evaluated by adding initial investment to operational cost considering efficiency of equipment, cost of equipment, fuel and electricity. To confirm the validity of the developed program, a hotel building with an area of $127,960m^2$ was selected, and the simulated results were compared with the measured data. The difference between the simulated and the measured values for the selected hotel building was approximately 12% for annual electric consumption.

  • This research aims at developing and distributing models and indexes that can evaluate ubiquitous information projects in order to enhance the objectivity and validity of their evaluation. The research adopts a BSC(Balanced Score Card) concept with four views, economic, policy, social, and technical views. The research induces a model of pre-evaluation and a model of post-evaluation according to each view. In order to secure the validity of the models, they are revised and complemented by obtaining advice through interviews with five experts in related fields, and the validity and application possibility of the indexes are verified by surveying ten people working in those fields. Finally, investigating their weights according to the importance of each view and index, they are evaluated using an AHP (Analytic Hierarchy Process) method.

  • Selecting individuals with ideal pilot aptitude is crucial to minimizing aviation accidents caused by human error and preventing economic losses due to dropouts during flight training. Specifically, the Republic of Korea Air Force implemented a new computer-based pilot aptitude test tool in 2018, which integrates cognitive ability tests and psychomotor ability tests. Additional research is necessary to overcome the limitations identified during the development phase. In this study, we analyzed the predictive validity of the newly developed pilot aptitude test by examining how well it predicts actual flight training performance among 1,078 Air Force officers. The results indicated that the test effectively predicted the completion of each training phase. Based on these findings, theoretical and practical implications were discussed.

  • Urban parks are progressing but are in chaos in the twenty-first century. Therefore the purposes of this study are to consider critically and classify the new paradigm of urban parks. Urban parks are one of the space products, and progressing aspects can be divided into three parts; supply, demand and market aspects. In the abstract, urban parks' progress represents process, openness or voidness, general and cultural ecology, productivity, experience program, identity or sense of place, carriers of urban regeneration, urban infrastructure, community space, multi-layered activity, active space, communication with urban space, tool of low carbon strategy and consilience. But urban parks have come under increased criticism about the long period development on trees growth, covering open space, limitation of general and cultural ecology, production, activity programs, identity and community space, visible urban regeneration, economic validity, urban sprawl, not using as the low carbon strategy, and finally negative consilience with contiguous fields. We collected these critical consideration about progressing urban parks, and proposed urban agricultural park as one of the alternative urban parks. This is closely connected with sustainable region development, low-carbon society, local food, well-being, Lohas paradigm and amenity of urban life.

  • Purpose: This study was conducted to identify the factors influencing of HPV vaccination and vaccination intention among Korean adult women through a systematic review. Methods: A systematic review was conducted across international and domestic electronic databases and nine of 193 studies were identified for this review. Results: Meaningful variables influencing HPV vaccination and its intention included socioeconomic status (age, economic level, and education level), knowledge level, health beliefs, attitudes toward HPV vaccination, and previous experiences. Economic level and knowledge influenced HPV vaccination and vaccination intention, which was consistent with the results of previous studies. Eight studies measured knowledge level regarding cervical cancer or HPV vaccination; however some instruments lacked reliability and validity report. Conclusion: There is a need for governmental support to reduce the burden of HPV vaccination cost, to publicize the benefits and to provide general information regarding HPV vaccination. Finally, it is necessary to develop an instrument with confirmed reliability and validity to measure HPV knowledge.
