  • In this work, a PC-based thermal performance monitoring system is developed for the nuclear power plants. The system performs real-time thermal performance monitoring and diagnosis during plant operation. Specifically, a prototype for the KORI-2 nuclear power unit is developed and examined in this work. The analysis and the fault identification of the thermal cycle of a nuclear power plant is very difficult because the system structure is highly complex and the components are very much inter-related. In this study, some major diagnostic performance parameters are selected in order to represent the thermal cycle effectively and to reduce the computing time. The Fuzzy ARTMAP, a self-organizing neural network, is used to recognize the characteristic pattern change of the performance parameters in abnormal situation. By examination, this algorithm is shown to be able to detect abnormality and to identify the fault component or the change of system operation condition successfully. For the convenience of operators, a graphical user interface is also constructed in this work.

  • In this study, a computerized nutritional and health guide program for workers was developed. The dietitian at the work site could utilize periodically conducted medical examination data to develop an effective health care counseling model based on the developed Nutritional and Health Guide Program. A personal computer (Pentium II PC MMX-150, 32MB RAM, 2.95 GB HDD) with Microsoft Visual Basic 6.0 Enterprise Edition and Microsoft Access 97 installed, was used. The Nutritional and Health Guide Program consisted of seven main menus and 43 sub-menus. Included in the main menu were Basic Information, Periodic Health Check-ups, Visitors' Consultations, Nutritional/Health Tips, Nutritional Education according to Diseases, Help and Exit. In the Periodic Health Check-up menu, dieticians could input the health examination data of employees and touch for the recommended treatments for diseases such as obesity, diabetes, high cholesterol, hypertension and hepatitis. The Visitors'Consultation menu has been designed to compile health information about the employees who sought consultations. The Nutritional/Health Tips menu was designed to provide 14 kinds of programmed nutritional educational media and information. In the Nutritional Education According to Diseases menu, the dietitian could judge the subject's willingness to obtain treatment based on the Stage of Change Model. According, the content of the administered respective nutritional education was classified by stages. The Help menu, provide a chart of the method and procedure used as nutritional guidelines, by which the results of the health examination were classified as people in good health and those requiring special medical attention. The results of the evaluation of this program showed highly positive rates for usefulness (4.09), convenience (4.04), lettering size (4.02), interest (3.93), design (3.49). It also showed that 97.5% of the subjects thought that this program would be helpful for implementation of their company's nutritional educational program. Therefore, this menu could help dietitians plan, conduct, and evaluate their nutritional guidelines for employees. It is expected that The Nutritional and Health Guide Program developed in this study will play a role as a scientific and effective guide in conjunction with health examination results.

  • Since 1971 when the nation wide 'New Community' movement was launched to improve rural standards of living, dol and thatched-roof houses have been reshaped or removed, thereby making it hard to find time-honored people's living structures in the countryside. Since 1977, the improvement work of rural houses has started throughout the country, so many new rural residences have been constructing along the highway, main roads, railways and around the sightseeing area, New rural houses do not show, for the most part, the traditional architectural style and the nation's unique conventional ways of living. The writer tried to find solutions to the problems derived from improvement work of rural residence, in a comparative method of traditional rural houses and newly constructed rural ones. The greater part of new rural houses' types, painting colors, and fence types had been recommended by provincial administrative trative officials. Officials recommended them to the farmer with their standards, which did not consider farmer's convenience of traditional way of life, but a fine sight from the highways or railways. Korea's three basic roof types are the HAPKAK roof (gabled and hipped), the UCHINKAK roof(hipped), and the BAKKOONG roof(gabled). However, the gabled roof houses, having their entrance on the gabled side, are found more ofter in new rural village. As mentioned above, architectural style is not harmonious with the topography and climate i Korea, because it is not Korean traditional type, but one of the western styles. And new rural house plans are inconvenient in the conservation rural family system, because of the same category with urban houses plans. Other problems derived from ton-traditional architecture style are roof painting in 4-5 colors in a new village, types of wall and fence, and attached building in the site.

  • Gondola is widely used as a construction facility to perform external finishing work without using scaffolding at a construction site. However, since 2000, there have been 17 deaths from now so these risks associated with work can not be ignored. Therefore, it is expected that it will contribute greatly to prevent related disasters if introducing necessary measures to prevent repeated related disasters and installing additional safety devices. In order to eliminate the risk factor according to the operation of the gondola, it is necessary for the operator to use it to use it while the examination of each product is completed, and to use the over load Dangerous arbitrary measures such as arbitrary operation of the prevention device, removal of the safety fence for convenience of work, installation of the wire rope installed in the air, falling out of the wire rope and falling to the ground Do not perform such sealing measures so that any operation of the overload prevention device can not be done so as not to take such arbitrary measures, or wire the power supply wire to the safety fence so as not to delete the safety fence. Then, when the safety fence is removed, so that it does not become a gondola operation, or when replacing the wire rope in the air, to prevent the wire rope from coming off, Additional measures such as installing falling down prevention device may be necessary.

  • Purpose: This study aimed to predict the influencing factors and the consequences of near miss in nurses' medication error based upon Salazar & Primomo's ecological system theory. Methods: A convenience sample of 198 nurses was recruited for the cross-sectional survey design. Data were collected from July to September 2016. Using the collected data, the developed model was verified by structural equation modeling analysis using SPSS and AMOS program. Results: For the fitness of the hypothetical model, the results showed that $x^2$ ($x^2=258.50$, p<.001) was not fit, but standardized $x^2$ ($x^2/df=2.35$) was a good fit for this model. Additionally, absolute fit index RMR=.06, RMSEA=.08, GFI=.86, AGFI=.81 reached the recommended level, but the Incremental fit index TLI=.82, CFI=.85 was not enough to reach to the recommended level. With the path diagram of the hypothetical model, caution (${\beta}=-.29$ p<.001), patient safety culture (${\beta}=-.20$, p=.041), and work load (${\beta}=.18$, p=.037) had a significant effect on the near miss experiences in nurses' medication error, while fatigue (${\beta}=-.06$, p=.575) did not affect it. Moreover, the near miss experience had a significant effect on work productivity (${\beta}=-.25$, p=.001). Conclusion: These results have shown that to decrease the near miss experience by nurses and increase their work productivity in hospital environments would require both personal and organizational effort.

  • In the era of the fourth industrial revolution, data plays a vital role in enhancing the productivity of industries. To advance digitalization in the construction industry, which suffers from a lack of available data, this study proposes a model that classifies construction site photos by work types. Unlike traditional image classification models that solely rely on visual data, the model in this study includes semantic analysis of construction work types. This is achieved by extracting the significance of relationships between objects and work types from the standard construction specification. These relationships are then used to enhance the classification process by correlating them with objects detected in photos. This model improves the interpretability and reliability of classification results, offering convenience to field operators in photo categorization tasks. Additionally, the model's practical utility has been validated through integration into a classification program. As a result, this study is expected to contribute to the digitalization of the construction industry.

  • This study examines the influence of the physical environment on tourist's emotional response and behavioral intention in the tourist destination. The research was mainly performed in leading tourist destinations of Busan Metropolitan City (Haeundae, Gwanganri & Songjeong area) by the sampling survey method in April-May 2013. The results demonstrate as follows. Firstly, the tourist's convenience and amenity in physical environments have significant impacts on the negative feeling of emotional response, but attractiveness did not influence in negative feeling. By contrast, the attractiveness and amenity the a of physical environments give significant impacts on the positive feeling of emotional response but convenience did not work in positive response. Secondly, both positive and negative feeling of emotional responses give meaningful impacts on Tourist's behavior intention. According to the meaningful relationship between physical environment and emotional response, the regional characteristics and effective marketing management of tourism resource and preparedness should be considered in setting up tourist facilities.

  • The purpose of this study is to illustrate the design of safety suits based on energy-harvesting technology, particularly targeting street cleaners who must work at night with high mobility. The design focuses on applying lightweight energy-harvesting tools and illuminant into the wear. The design development reflects feedback from testers collected via survey constituting a key methodology. The development process has two main stages. Each stage uses a process of design prototyping, internal examination, test sampling, test wearing, and wearers' feedback via survey that consists of questions on visibility, wearing convenience, and washability. The first stage results show the design of safety suits with energy-harvested LED illuminant inserted and the survey results collected from street cleaners dressed in 4 sample and 80 actual suits in total. Improved based on the first-stage survey results, the second stage designs the suits with detachable energy-harvested EL tape. From these 5 sample and 30 actual second-stage suits, the additional survey indicates that this second-stage design facilitates more visibility and convenience in washing and wearing than the first-stage design. Accordingly, one can expect that this new design can apply not only to safety suits for night workers but also to handicapped or outdoor sportswear applications in the future.
