  • Plants which are having conditions of high temperature and pressure always are exposed to danger. In order to prevent unexpected accidents, safety management that can effectively and appropriately examine facilities is required in plant operation. RBI(Risk-Based Inspection) technology in API 581 is one of standard management technique for evaluating risk on petroleum plants. There are qualitative and quantitative assessments in RBI methodology. Quantitative evaluation step is complex and required much information, so high-risk facilities in plant are selected firstly by qualitative method. Qualitative RBI is performed by choosing the answer in prepared questionnaire. However, it is difficult to believe thoroughly results from survey including ambiguous information. In this study, the procedure of qualitative RBI analysis with considering probability distribution concept were proposed by using Monte Carlo simulation method in order to increase reliability in spite of uncertain factors. In addition, qualitative risk of cooling system for LNG plant was evaluated using proposed procedure. Although 20 items of total 39 assessment items are applied to uncertain factors, risk section of high probability(89%) were verified. The detailed results were described in manuscript.

  • Purpose : The purpose of this study was to analyze Korean qualitative research studies on cerebral palsy and provide a basis for future direction of research. Methods : Twenty-six articles were selected by searching 4 Korean databases (NDSL, DBpia, KISS, and RISS) and reviewing the list of additional references. All the articles were analyzed and assessed using the Consolidated criteria for Reporting Qualitative research (COREQ). Results : Seventeen qualitative studies and 9 mixed quantitative and qualitative studies were selected, and methodologies such as case study (42.3 %), constant comparative method (23.1 %) and phenomenology (23.1 %) were used. The studies investigated the effects of interventions (38.5 %), support programs (30.8 %), and life experiences (26.9 %). Among the participants, 50.0 % were persons with disabilities only, 19.2 % were parents only, and 30.8 % were combination of persons with disabilities, parents, teachers, and therapists. The number of participants in most studies was 2-9 (57.7 %). The COREQ evaluation of the selected articles revealed many shortcomings in the studies. Interview guidelines were used only in 26.9 % of the studies. In particular, many articles did not describe in detail the characteristics of researchers and the relationship between researchers and the participants. Conclusion : In future, various research methodologies and research checklists must be used to stimulate high-quality qualitative research with on cerebral palsy.

  • This research is to restructure the public assessment of housing management in a standardized fashion, and a self-administered questionnaire survey was employed for data collection and analysis. In doing so, all the assessment tools nationwide were identified and assembled to extract the items included in the survey form. The survey form was mailed out to local officers in charge of housing management and professional housing managers in the nation, and the responses were statistically analyzed in order to structure the standard assessment tool of housing management. This research classified 3 main areas (General Maintenance, Operation and Community Living) in evaluating the housing management performance, and identified 35 essential items and 52 optional items. The 35 essential items were drawn from the 16 categories of the 3 areas (11 items of 5 categories for General Maintenance, 7 items of 4 categories for Operation, and 17 items of 7 categories for Community Living), and the rest 52 optional items were from the 16 categories of the 3 areas (24 items of 7 categories for General Maintenance, 26 items of 7 categories for Operation, and 2 items of 2 categories for Community Living). While all the items in the research are quantifiable, it's suggested that qualitative measurements be complementarily utilized in the assessment not only to explore the best practices of housing management but also to refine and modify the standardized tool in response to various environmental changes. As the public assessment of housing management is context-sensitive and critically related to local housing profile, the continuous implementation of the assessment will facilitate shifting the housing paradigm from production and consumption to management and reproduction.

  • Purpose: Oral and facial sensation is affected by various factors, including trauma and disease. This study assessed the clinical profile of patients diagnosed with sensory dysfunction and investigated their sensory perception using simple qualitative sensory tests. Methods: Based on a retrospective review of the medical records, we analyzed a total of 68 trigeminal nerve branches associated with sensory dysfunction in 52 subjects. We analyzed the frequency and etiology of sensory dysfunction, and the frequency of different types of sensory perception in response to qualitative sensory testing using tactile and pin-prick stimuli. Results: The inferior alveolar nerve branch was the most frequently involved in sensory dysfunction (88.5%). Third molar extraction (36.5%) and implant surgery (36.5%) were the most frequent etiological factors associated with sensory dysfunction. Hypoesthesia was the most frequent sensory response to tactile stimuli (60.3%). Pin-prick stimuli elicited hyperalgesia, hypoalgesia, and analgesia in 32.4%, 27.9%, and 36.8%, respectively. A significant association was found between the two kinds of stimuli (p=0.260). Conclusions: Sensory dysfunction frequently occurs in the branches of the trigeminal nerve, including the inferior alveolar nerve, mainly due to trauma associated with dental treatment. Simple qualitative sensory testing can be conveniently used to screen sensory dysfunction in patients with altered sensation involving oral and facial regions.

  • A wide spectrum of risk assessments including qualitative and quantitative approaches and the analyses of its consequence were performed for an environmentally sensitive object such as incineration facility. To find out the major risk concerns, HAZOP(Hazard and Operability) were performed. Then, the frequency of hazardous gas release scenarios was calculated. Finally consequence analyses were performed for the gas release scenarios. On the basis of analyses through evaluation, a more innovative way for making a better control system or the enhancement of operation procedure was given. The results from these analyses would act as a substantial benefits for the incineration facility operator, and giving some measured information for the neighbors and the people involved.

  • LHR(Landfill Site Hazard Ranking Model) was developed for ranking the relative hazard of landfill sites by using the method of value-structured approach. LHR consists of combining a multiattribute decision-making method with a Qualitative risk assessment approach. A pairwise com parisian method was applied to determine weights of landfill site factors related. To determine the hazard of landfill site, hydrogeological factors, waste characteristics factors and receptors factors were evaluated by LHR. LHR can help decision-makers prioritization of remediation of landfill sites through the relatively convenient and concise evaluation method of landfill site features related. LHR focuses mainly on pathways of groundwater and surfacewater for evaluating landfill hazard to receptors including humans. To validiate the applicability of LHR, Nanjido Landfill site, Metropolitan Landfill site, and Hwasung Landfill site were evaluated.

  • Based on ASME probabilistic risk assessment (PRA) and NEI PRA peer review guidance, we evaluate a human reliability analysis (HRA) in probabilistic safety assessment (PSA) for Korea standard nuclear power plants, Ulchin Unit 3&4, to improve it performed at under design. The HRA for Ulchin Unit 3&4 is assessed as higher than Grade I based on ASME PRA standard and as higher than Grade 2 based on NEI PRA peer review guidance. The major items to be improved identified through the evaluation process are the documentation, the systematic human reliability analysis, the participitation of operators in the works and review of HRA. We suggest the guidance on the identification and qualitative screening analysis for pre-accident human errors and solve some items to be improved using the suggested guidance.
