Probabilistic safety assessments (PSA) have been used for several decades to visualize the risk level ofcommercial nuclear power plants (NPPs). Since the role of a human reliability analysis (HRA) is to providehuman error probabilities for safety critical tasks to support PSA, PSA quality is strongly affected by HRAquality. Therefore, it is important to understand the underlying limitations or problems of HRA techniques. For this reason, this study conducted a survey among 14 subject matter experts who representthe HRA community of domestic Korean NPPs. As a result, five significant HRA issues were identified: (1)providing a technical basis for the K-HRA (Korean HRA) method, and developing dedicated HRA methodsapplicable to (2) diverse external events to support Level 1 PSA, (3) digital environments, (4) mobileequipment, and (5) severe accident management guideline tasks to support Level 2 PSA. In addition, anHRA method to support multi-unit PSA was emphasized because it plays an important role in theevaluation of site risk, which is one of the hottest current issues. It is believed that creating such a catalogof prioritized issues will be a good indication of research direction to improve HRA and therefore PSAquality.

Objectives : The purpose of this study was to evaluate the reliability and validity of the Korean version of Preschool Temperament and Character Inventory (K-psTCI), a questionnaire based on Cloninger's seven-factor model of personality. Methods : The psTCI was translated into Korean and administered to 266 children aged 2-6 years. α test-retest study of the K-psTCI was conducted across a 4-month interval, Internal consistency was calculated by Cronbach a. Test-retest and reliability was analyzed by Pearson correlation analysis. Factor analyses for the temperament and character dimensions were performed using principal component analysis, rotating factors by varimax. The psTCI scores of Korean and United States preschoolers were compared Results : Cronbach α values for the K-psTCI scales ranged from .62 to .78 for each dimensions. Test-retest correlations (r) ranged from .50 to .77 for each dimensions. Explorative factor analysis with the condition of eigenvalue greater than 2 produced four factors for the temperament items and three factors for the character items like the US original version of psTCI. Through factor analyses, five items in the K-psTCI were categorized differently from the US version of psTCI. Korean preschoolers had higher mean scores on Cooperativeness (CO) in males as compared to a sample of US preschoolers. Conclusion : The results of this study suggests that the Korean preschool TCI is satisfactory in reliability and validity.

Osteosarcoma is a malignant tumor arising from the undifferentiated fibrous tissue of bone and one of the most common primary malignant tumors of bone. The diagnosis of osteosarcoma is based on clinical, radiological and histopathological findings, but the majority of the patients with osteosarcoma can be diagnosed with a reasonable degree of confidence from the combination of the lesion site, age and radiological findings. This is a clinical and radiological observation of 40 cases of osteosarcoma which were experienced at Chonnam National University Hospital, Chosun University Hospital and Kwangju Christian Hospital from 1978 to 1981. The results were as follows : 1. The peak incidence was in the age group from 10 to 19 years in 21 cases (52.5%). 2. In sex distribution, male group showed slightly higher incidence than in female group with the ratio of 1.35 : 1. 3. The most commonly affected site was proximal tibia (35%). The lesion was found around the knee in 65% of the studies cases. 4. Increment of the level of serum alkaline phosphatase was observed in 25 cases (62.5%), and the average value of serum alkaline phosphature in these cases was 5.6 Bessay Lowry units. 5. Radiographically, osteoblastic type was 14 cases (35%), osteolytic type 9 cases (22.5%) and mixed type 17 cases (42.5%). 6. Cortical destruction was obsdrved in 30 cases (75%), and soft tissue mass shadow with calcification was observed in 34 cases (85%). 7. Solid periosteal reaction, sunburst periosteal reaction and Codman's triangle were observed in 35%, 57.5% and 22.5% respectively. 8. At the first visit, lung metastasis was found in 5 cases (12.5%) and inguinal lymphnode metastasis in 2 cases (5%).

The contribution of degraded human performance (e.g., human errors) is significant for the safety ofdiverse social-technical systems. Therefore, it is crucial to understand when and why the performance ofhuman operators could be degraded. In this study, the occurrence probability of human errors wasempirically estimated based on the complexity of proceduralized tasks. To this end, Logistic regressionanalysis was conducted to correlate TACOM (Task Complexity) scores with human errors collected fromthe full-scope training simulator of nuclear power plants equipped with analog devices (analog environment). As a result, it was observed that the occurrence probability of both errors of commission anderrors of omission can be soundly estimated by TACOM scores. Since the effect of diverse performanceinfluencing factors on the occurrence probabilities of human errors could be soundly distinguished byTACOM scores, it is also expected that TACOM scores can be used as a tool to explain when and why theperformance of human operators starts to be degraded
