Tube Lines has carried out a "knowledge and investigation programme" on the deep tube tunnels comprising the Jubilee, Northern and Piccadilly lines, as required by the PPP contract with London Underground. Many of the tunnels have been in use for over 100 years, so this assessment was considered essential to the future safe functioning of the system. This programme has involved a number of generic investigations which guide the assessment methodology and the analysis of some 5,000 individual structures. A significant amount of investigation has been carried out, including ultrasonic thickness measurement, detection of brickwork laminations using radar, stress measurement using magnetic techniques, determination of soil parameters using CPT, pressuremeter and laboratory testing, installation of piezometers, material and tunnel segment testing, and trialling of remote photographic techniques for inspection of large tunnels and shafts. Vibrating wire, potentiometer, electro level, optical and fibre-optic monitoring has been used, and laser measurement and laser scanning has been employed to measure tunnel circularity. It is considered that there is scope for considerable improvements in non-destructive testing technology for structural assessment in particular, and some ideas are offered as a "wish-list". Assessment reports have now been produced for all assets forming Tube Lines' deep tube tunnel network. For assets which are non-compliant with London Underground standards, the risk to the operating railway has to be maintained as low as reasonably practicable (ALARP) using enhanced inspection and monitoring, or repair where required. Monitoring techniques have developed greatly during recent years and further advances will continue to support the economic whole life asset management of infrastructure networks.

In this paper, all elements used in integrated infrastructure for job competency assessments of NCS (National Competency Standards) will be merged into assessment system using multiple devices(ASMD). NCS is a systematic approach on required abilities (knowledge, technical expertise, attitude) to process the tasks in the fields by industry. Competiveness of ASMD design is that no limitation of time and space using personal devices like PC, laptop, smartphone, and tablet, while seeing screen, hearing, touching, speaking, and writing. Question type can be limitless to express the situation. To lead technologies and market for domestic and oversea assessment system, supporting on multiple devices with connectivity that will eliminate limitation of time and space is the key feature for design competitiveness. Design of integrated assessment system proposed in this paper can be applied to NCS, fundamental competency evaluation, online test, job aptitude test, and foreign language test which involve listening, reading, writing, and speaking. Compared with existing evaluation method, reduction of investment and operating cost will be greater. Along with development of ICT technologies, the next generation of integrated assessment system will be quickly changed to ASMD, which already involves connected service between internet and smart devices.

Purpose: The aim of this study was to develop and validate Detailed Clinical Models (DCMs) for pain assessment in nursing. Methods: First, we identified the entities of pain assessment from ICNP. We identified the attributes and values of the attributes to describe the entities in more detail by reviewing the literature. Data types and optionalities of the attributes were defined. Second, we modeled the DCMs by linking an entity and its corresponding attributes with values and by specifying the data types and optionalities of the attributes. Finally, the DCMs were validated by a group of domain experts using a content validity index. Results: In total, 19 DCMs with 11 attributes for pain assessment were developed. The experts' evaluations showed that the DCMs were valid enough to represent pain related information of nursing assessment. Conclusion: The DCMs developed in this study can be used in electronic nursing records. The DCMs for pain can ensure the semantic interoperability of pain related information in electronic nursing records.

As part of the safety case development for generic disposal sites in Korea, it is necessary to develop generic assessment models using various geosphere-biosphere interfaces (GBIs) and potentially exposed groups (PEGs) that reflect the natural environmental characteristics and the lifestyles of people in Korea. In this study, a unique modeling strategy was developed to systematically construct and select Korean generic biosphere assessment models. The strategy includes three process steps (combination, screening, and experts' scoring) for the biosphere system conditions. First, various conditions, such as climate, topography, GBIs, and PEGs, were combined in the biosphere system. Second, the combined calculation cases were configured into interrelation matrices to screen out some calculation cases that were highly unlikely or less significant in terms of the exposure dose. Finally, the selected calculation cases were prioritized based on expert judgment by scoring the knowledge, probability, and importance. The results of this study can be implemented in the development of biosphere assessment models for Korean generic sites. It is believed that this systematic methodology for selecting the candidate calculation cases can contribute to increasing the confidence of future site-specific biosphere assessment models.

This study has been attempted to measure health education needs-assessment of middle-aged women and to analyze the factors affecting health education needs-assessment. There were 618 subjects(middle-aged women, 40 to 59 years of age). The major findings of the study were as follows: 1. Seventy six point six percent of the respondents wanted health education. The remainder did not want health education because of the lack of the time. 2. For those desiring to receive health education, there was statistically significant difference in education(p〈0.001), income(p〈0.05), employment(p〈0.05), recreation(p〈0.001), knowledge on health(p〈0.001), routine medical check-ups(p〈0.01) and health education experience(p〈0.001). 3. Forty nine percent of the respondents wanted formal education as a way of education and 41.7% wanted life-long education center for the place of education. Sixty two point five percent of responded that ‘once a month’ is adequate for the health education, and 62.7% felt that ‘around one hour’ duration is appropriate. 4. The area the respondents were most interested in was disease control especially in the order of cancer and osteoporosis. 5. There was statistically significant difference between the age group of 40's and 50's in personal health care and environmental health area(p〈0.01), weight control area(p〈0.01), mental health and exercise area(p〈0.05), drinking and smoking area(p〈0.01). 6. The more knowledge on health, the higher health education needs-assessment. Middleaged women who received routine medical check-ups had more health education needs-assessments than those who didn't.

The pond wetlands in agricultural landscape are important natural resources that carry out the function of bio-diversity conservation. However, recently, those have been gradually embedded as their utility value were disappeared. And, the assessment methods used for pond wetlands are insufficient. Therefore, this study was conducted to examine the conservation value of pond wetlands by using the modified RAM, and present the improvement of assesment methods. The study sites, a total of 32 pond of 4 types by land use, were selected on the basis of Ramsar Convention. Through the analysis of precedent studies, the weighted 8 functions were adjusted. According to the assessment results, pond wetlands made the largest contribution to Fishery and Herpetile Habitat function. In addition, it also made large contribution to Floral Diversity, Wildlife Habitat, and Water Quality Protection function. On the other hand, it made a small contribution to Aesthetics and Recreation, Runoff Attenuation, Shoreline /Stream Bank Protection, and Flood/Storm Water Storage function due to the characteristics of small-scale pond wetlands. In the assessment of 8 functions, house type showed the worst assessment result, and mountain type showed the best assessment result. It is thought that those are due to land use type in terms of vicinity. 10 items among 52 of the modified RAM showed the same assessment results in all land use types. Accordingly, it is required to be deleted and modified the assessment method. On the other hand, it is required to add age, interference, and water use to the assessment method. It is thought that these results can be utilized for the development and modification of assessment methods focused on pond wetlands in rural area.

The purpose of this study was to provide basic data for practical HACCP training. A survey was conducted and analysed on 46 contract foodservices: 13 "Appointed" foodservices (appointed by Korean Food & Drug Administration), 17 "Voluntary Applying" foodservices (voluntarily applied HACCP, but not appointed), 16 "Non-applying" foodservices (not applied HACCP). Hygiene knowledge and recognition on job performance levels for HACCP application for 46 dieticians and 361 employees were surveyed. According to the survey, 61.5% of the "Appointed" dieticians took HACCP training from outside the company, 58.8% of "Voluntary Applying" dieticians took in-house HACCP training, and 62.4% of "Non-applying" dieticians have not taken any HACCP training. As for the comparison of hygiene knowledge, total mean of employees (6.38) showed significantly lower average than that of the dieticians (7.82) (p<0.001). From the result for recognition on job performance levels, total mean of dieticians (3.91) indicated generally good performance while employees (3.41) (p<0.001) showed considerably lower recognition. Hygiene knowledge and recognition on job performance levels of both dieticians and employees showed considerably close correlation (p<0.01 or p<0.05).
