  • A coupled model system for Wind Resource Assessment (WRA) was studied. Using a mesoscale meteorological model, the Weather Research and Forecasting (WRF) model, global-scale data were downscaled to the inner nested grid scale (typically a few kilometers), and then through the coupling Computational Fluid Dynamics (CFD) mode, FLUENT. High-resolution results (50 m in the horizontal direction; 10 m in the vertical direction below 150 m) of the wind speed distribution data and ultimately refined wind farm information, were obtained. The refined WRF/FLUENT system was then applied to assess the wind resource over complex terrain in the northern Poyang Lake region. The results showed that the approach is viable for the assessment of wind energy.

  • In the framework of the SPEAR (Seismic PErformance Assessment and Rehabilitation) research Project, an under-designed three storey RC frame structure, designed to sustain only gravity loads, was subjected, in three different configurations 'as-built', Fiber Reinforced Polymer (FRP) retrofitted and rehabilitated by reinforced concrete (RC) jacketing, to a series of bi-directional pseudodynamic (PsD) tests under different values of peak ground acceleration (PGA) (from a minimum of 0.20g to a maximum of 0.30g). The seismic deficiencies exhibited by the 'as-built' structure after the test at PGA level of 0.20g were confirmed by a post - test assessment of the structural seismic capacity performed by a nonlinear static pushover analysis implemented on the structure lumped plasticity model. To improve the seismic performance of the 'as-built' structure', two rehabilitation interventions by using either FRP laminates or RC jacketing were designed. Assumptions for the analytical modeling, design criteria and calculation procedures along with local and global intervention measures and their installation details are herein presented and discussed. Nonlinear static pushover analyses for the assessment of the theoretical seismic capacity of the structure in each retrofitted configuration were performed and compared with the experimental outcomes.

  • The hazard assessment in which the potential hazard factors in the buildings are investigated and the scale of the hazard is analysed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment model by actual assessment of existing building. Also the checklist is prepared in itemized questionnaire from easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.

  • Purpose: The planning of medical facilities involves formulating a comprehensive medical basic plan, translating it into spatial dimensions through a space program. Feasibility assessment often relies on empirical methods like floor area per bed. However, with the shift towards specialized medical concepts, proportional scaling to bed numbers is challenging. This study proposes scale planning improvements during the feasibility assessment stage for comprehensive hospitals, analyzing cases using area determination factors and standard areas based on medical resources. Methods: The Korean Development Institute's Public Investment Management Center (KDI) identified issues in the scale determination of medical facilities in the Preliminary Feasibility Study Guidelines and investigated alternative approaches for determining the scale of a case that passed the preliminary feasibility study in 2019. The study assessed the feasibility of applying individual factors to determine not only the number of beds but also the scale at the sector and department levels. Additionally, a statistical analysis was conducted to examine the correlation between the total number of beds and various area determination factors. Results: Results suggest a strong correlation between total beds and major equipment needs, but in hospitals with <500 beds, this correlation weakens. Ward section scale is better calculated per ward type, not just total beds. Outpatient department scale depends on specialists, influencing treatment room numbers. Medical personnel play a crucial role in determining the scale of sections like rehabilitation therapy rooms, operating rooms, dialysis rooms, and overall facility scale.

  • The fundamental assumption that thresholds exist for noncarcinogenic toxic effects of chemicals is reviewed; this assumption forms the basis for the no-observed-effect level/ safety-factor (NOEL/SF) approach to risk assessment for such effects. The origin and evolution of the NOEL/SF approach are traced, and its limitations are discussed. The recently proposed use of dose-response modeling to estimate a benchmark dose as a replacement for the NOEL is explained. The possibility of expanding dose-response modeling of non carcinogenic effects to include the estimation of assumed thresholds is discussed. A new method for conversion of quantitative toxic responses to a probability scale for risk assessment via dose-response modeling is outlined.

  • The purpose of this study was to determine the effect of mechanical horseback riding training on trunk control, balance function in stroke patients. 15 stroke patients were recruited for this study. The subjects were randomly assigned to two groups: experimental(n=7) and control(n=8). All subjects received a routine physical therapy. The mechanical horseback riding training was for 30 min in the case of the EG subjects. This study was carried out approximately 8 weeks from March 4 to May 3. The assessment tools of this study involved the trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test. The measurements were recorded before the intervention and after the intervention. In the cases of the EG subjects and CG subjects, the variables measured after the intervention significantly differed from trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test before the intervention (p<.05). Also, there were significant differences in trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test at post test between the 2 groups (p<.05). The findings indicate that mechanical horseback riding training exerts a positive effect on trunk control, balance function in stroke patients. Further studies are required to generalize the result of this study.

  • Objectives : Thyroid function is associated with psychiatric disturbance such as mood symptoms, cognitive functions, anxiety and sleep problem. We evaluate the effects of thyroid dysfunction on negative symptoms of schizophrenia, mood symptoms and somatic symptoms in patients with schizophrenia. Methods : Sixty five patients with schizophrenia were recruited. The patients were classified into two groups; the patients with the history of abnormal thyroid indices level(group of abnormal thyroid function) and the patients without the history of normal thyroid indices level(group of normal thyroid function). At baseline and 8 weeks later, psychiatric symptoms were assessed with the Scale for the Assessment of Negative Symptoms (SANS), the Scale for the Assessment of Positive Symptoms(SAPS), and Beck Depression Inventory(BDI), Somatosensory Amplication Scale(SSAS). Results : During 8 weeks, there were significant differences in the changes of SANS, BDI, SSAS between group of abnormal thyroid function and group of normal thyroid function. Compared to group of normal thyroid function, group of abnormal thyroid function showed greater reduction of the scores of SANS(23.3%), BDI (19.6%), and SSAS(16.2%), respectively. However, there was no significant correlation between the scores of SANS, BDI, and SSAS. Conclusion : Our study suggested that abnormal thyroid indices would predict the prognosis of negative symptoms, mood symptoms, and somatic symtpoms in patients with schizophrenia.
