Purpose: This study was conducted in order to evaluate the reliability, validity, sensitivity, and specificity of the Short Form of Bobath Memorial Hospital Fall Risk Assessment Scale (BMFRAS-SF). Methods: A validation study was conducted on 207 elderly patients aged over 65 who were admitted to Bobath Memorial Hospital. Fall risk scores of BMFRAS, composed of eight subscales (age, fall history, physical activity, consciousness level, communication, fall risk factors, underlying disease, and medications) were assessed from the electronic medical record. BMFRAS-SF was derived from eight subscales of the BMFRAS representing the significance between fallers and non-fallers (fall history, physical activity, fall risk factors, underlying disease, and medications). Internal consistency reliability and interrater reliability were assessed by Cronbach's alpha and kappa coefficient. Validity was assessed by Spearman correlation analysis, factor analysis. Sensitivity, specificity, positive predictive and negative predictive values, and a receiver-operating characteristic curve (ROC) were generated. Results: Fallers had significantly higher risk scores than non-fallers in fall history, physical activity, fall risk factors, underlying disease, and medication scales. The BMFRAS-SF demonstrated acceptable Cronbach's alpha (.706) and kappa coefficients of .95. The BMFRAS-SF subscales showed good convergent validity and construct validity. The BMFRAS-SF presented good sensitivity(86.7%), specificity(67.9%), positive predictive value(42.9%) and good negative predictive value(94.8%) at a cut-off score of 5. Areas under the ROC curves were .860 for the BMFRAS and .861 for the BMFRAS-SF. Conclusion: The BMFRAS-SF was proved to be reliable and valid. It could be used for time-saving assessment and evaluation of the high risks for falls in clinical practice settings.

학교에서의 수학 평가는 국가 교육과정과 일관되게 이루어져야 한다. 본 연구는 예비교사들이 교육과정에 충실하게 평가 문항을 개발한 과정을 분석하였다. 예비교사들은 교육과정에 대한 지식을 이미 갖추었지만 평가 문항에 교육과정을 충실하게 반영하지 못했다. 그러나 동료들과 여러 차례의 검토와 수정 과정을 거친 토론 속에서 평가 문항의 교육과정 충실도는 점점 더 높아졌다. 그리고 예비교사들은 토론을 통한 문항 수정을 하면서 교육과정 외에 출제자의 의도에 부합하게 문항을 구성하고, 학생들이 문항을 쉽게 이해할 수 있도록 돕고, 문항들 간의 일관성을 갖기 위한 의견을 제시하면서 문항의 완성도를 높여 갔다.

Interests in tourism and leisure have increased with the quality of life in Korea. The government takes the lead in development of tourism for balanced development between regions and local governments use development of tourism as a means for vitalization of local economy. The sustainable and eco-friendly development plan is required for the tourism development, because it needs effective use of limited natural resources and consideration of environmental capacity in the region. This study analyzed the trend of tourism development during nine years, and problems with respect to planning and environment aspects on the basis of four examples which follow recent development trend. We suggest improvement plan that 1) establishment of consistency and systematics of tourism development, 2) enforcement of setting up regional tourism development plan, 3) comprehensive and systematic plan establishment in consideration of private sector, 4) reasonable adjustment and environmental management for development project of approval organization, 5) removal of duplicate regulations for development project. Application of the improvement plan while setting up tourism plan could contribute to vitalization of local economy, and environmental preservation and management.

According to the Fourth Assessment Report of Intergovernmental Panel on Climate Change(IPCC) Working Group III, climate change is already in progress around the world, and it is necessary to execute mitigation in order to minimize adverse impacts. This paper suggests future climate change needs, employing IPCC Special Report on Emissions Scenarios(SRES) to predict temperature rises over the next 100 years. This information can be used to develop sustainable architecture applications for energy efficient buildings and renewable energy. Such climate changes could also affected the present supplies of renewable energy sources. This paper discusses one recent Fourth Assessment Report of IPCC (Mitigation of Climate Change) and the Hadley Centre climate simulation of relevant data series for South Korea. Result of this research may improve consistency and reliability of simulation weather data or climate change in order to take advantage of SRES and PRECIS QUMP. It is expected that these calculated test reference years will be useful to the designers of solar energy systems, as well as those who need daily solar radiation data for South Korea. Also, those results may contribute zero carbon and design of sustainable architecture establishing future typical weather data that should be gone ahead to energy efficient building design using renewable energy systems.

Objectives: Work stress is associated with non-communicable diseases, increased healthcare costs, and decreased work productivity among employees in the information technology sector. There is a need for regular work-stress screening among employees using valid and reliable tools. The Tool to Assess and Classify Work Stress (TAWS-16) was developed to overcome limitations in existing stress assessment tools in India. This study aimed to test the reliability of TAWS-16 in a sample of managerial-supervisory employees. Methods: This observational reliability study included data from 62 employees. Test-retest and inter-method reliability were investigated using a TAWS-16 web application and interview by telephone, respectively. Kappa values and intra-class correlation coefficients were calculated. Internal consistency was assessed through Cronbach's alpha. Results: For both test-retest and inter-method reliability, the agreement for both work-related factors and symptoms suggestive of work stress exceeded 80%, and all kappa values were 0.40 or higher. Cronbach's alpha for test-retest and inter-method reliability was 0.983 and 0.941, respectively. Conclusions: TAWS-16 demonstrated acceptable reliability. It measured stressors, coping abilities, and psychosomatic symptoms associated with work stress. We recommend using TAWS-16 to holistically identify work stress among employees during periodical health check-ups in India.

The Istanbul Strait is one of the important waterways in the world. And its southern entrance has a highly congested local traffic. Till now there are several studies regarding how the Istanbul Strait is dangerous to navigate and how those dangers can be mitigated. But there is no study regarding local traffic which is posing great collision risk. In a certain traffic area, marine traffic safety assessment parameters are traffic volume, frequency of collision avoidance maneuver, traffic density, traffic flow and potential encounter, In this paper local traffic volume, traffic flow and potential encounter number of local traffic vessels and possibility of collision are investigated in order to find degree of danger at the southern entrance of the Istanbul Strait. Finally by utilizing those, risky areas are determined for southern entrance of the Istanbul Strait. Results have been compared to a previous study regarding risk analysis at congested areas of the Istanbul Strait (Aydogdu, 2006) and consistency of the results were presented.

This paper presents the psychoacoustic analyses on the vehicle interior, noise generated when accelerating. Following the objective quantification for vehicle noises of different classes, the subjective decision process by the jury test is adopted to interrelate these results based on two different approaches. In particular, the paired comparison method is employed in assessing the sound quality in terms of the quietness, the powerfulness, and the pleasantness of the human auditory sensation. Special attention is paid to the physical interpretation of psychoacoutic parameters and their interrelation to the subjective assessment scores. In order to ensure the integrity of statistics of the survey, various tests are performed. The results show that the consistency of the "quiet" sensation is far higher than that of the "powerful" and the "pleasant" sensations. Also, it is found that the most significant parameter determining these feelings turns out to be the inherent loudness of the noise instead of the conventional indicators such as the weighted sound pressure level. It may be concluded that the psychoacoustic analysis offers more realistic evaluation for vehicle noise and assists the improvement of NVH more efficiently.ement of NVH more efficiently.

Purpose: This study identified the reasons why tuberculosis (TB) patients withhold treatment in a bid to develop a assessment scale to select patients who needs nursing intervention in the early stage and decrease the risk of discontinuation of treatment. Sample: There were two samples. A sample of 191 patients with TB and having primary treatment and a second sample of N who were under re-treatment Methods: The study design included qualitative and quantitative methods. Qualitative data were collected from in-depth interviews of TB patients under re-treatment. The quantitative data were collected from 191 patients with TB under primary treatment. Results: Exploratory factor analysis revealed 11 factors explaining 69.6% of total variance. These factors were categorized into four subgroups. A depression scale was used to establish concurrent validity. The depression scale had a positive relationship (r=54) with the discontinuing of primary treatment. The internal consistency reliability for the four subgroups was over .84. The confidence coefficient was Cronbach's ${\alpha}$ .95. The final scale was a self-reported four Likert scale including 50 items. Conclusion: Reliability and validity was established for the scale and the scale can be used to examine the risk of treatment discontinuation for TB. The scale is an important resource for nursing interventions in identifying and treating high risk clients.

The purpose of this study was to establish the reliability of the Trunk Impairment Scale (TIS) translated into Korea in patients with stroke. It also aims to score the quality of trunk movement and to be a tool for the treatment. The TIS consists of three subscales that static sitting balance, dynamic sitting balance and co-ordination. The TIS score ranges from a minimum of 0 to a maximum of 23. Twenty-five stroke patients (13 males, 12 females) were examined by two physiotherapists. Interrater and test-retest reliability were assessed. Kappa and weighted kappa values for the items of the trunk assessment of the TIS ranged from .67 to 1.00. Intraclass correlation coefficients for interrater and test-retest agreement were .95 and .97. Cronbach alpha coefficients for internal consistency range from .87 to .97. The TIS provide reliable assessments for the trunk and are valid scales for measuring trunk performance in patients with stroke. TIS can be used as a guideline for treatment and the assessment of quality of trunk activity.
