Abstract. The purpose of this study is to investigate the effect of targeted organizational forgetting on job performance through organizational learning mediating variable in Arvand Petrochemical Company. The current research, in terms of purpose, is in the applied research group and, in terms of research type, is in the category of descriptive-causal research. Given the data collection tools that aim to describe the circumstances or the phenomenon examined, this research is a descriptive study and since data collection in this study is supported by library studies and a questionnaire, it can be put into the field research group. The reliability of the questionnaire and its dimensions in this research was estimated using SPSS software and Cronbach's alpha. According to the result, which is above the minimum of 0.7, the reliability of the questionnaire was confirmed. Also, for the sake ofoptimization, the valuable comments of the professors were considered. The questionnaire consisted of three sections related to the considered variables and was ranked by Likert scale and the statistical population was measured. The coefficient between the variable of targeted organizational forgetting and the job performance equals to 0.590 and the corresponding t value is 9.649>1.96, so according to the t test, with a critical value of 0.05 at 95% confidence level, the null hypothesis can be rejected. As a result, with a 95% confidence, it can be said that targeted organizational forgetting has a significant effect on job performance. The results of the analysis of the first hypothesis of the research showed that "targeted organizational forgetting has a significant effect on job performance in Arvand Petrochemical Company".The coefficient between the targeted organizational forgetting and organizational learning equals 0.766 and the corresponding t value is 9.775>1.96, which according to t test with acritical value of 0.05 at a confidence level of 95%, the null hypothesis can be rejected. As a result, with a 95% confidence can be said that targeted organizational forgetting has a significant effect on organizational learning.The results of the analysis of the second hypothesis of the research showed that "targeted organizational forgetting has a significant effect on organizational learning in Arvand Petrochemical Company".The coefficient between organizational learning and job performance is 0.091 and the corresponding t value is 0.817<1.96, which according to t test with a critical value of 0.05 at 95% confidence level, the research hypothesis can be rejected. As a result, with 95% confidence, organizational learning cannot have a significant effect on job performance.

Distribution of diffuse plexiform neurofibroma on the body surface in patients with neurofibromatosis 1

Neurofibromatosis 1 (NF1) is a genetic disease characterized by cutaneous, neurological and osseous abnormalities. Approximately 20% of patients develop plexiform neurofibroma (PN), resulting in impaired quality of life. To evaluate distribution of diffuse PN on the body surface, a retrospective study was conducted for 354 patients with NF1 from 2007 to 2018 in Japan. We investigated a total of 40 patients with clinically apparent superficial diffuse PN. In the cases evaluated, 57.4% of the diffuse PN were located on the trunk, 19.2% the head and neck, 12.8% the lower limbs and 10.6% the upper limbs. Remarkably, 75.0% of the diffuse PN were located on the dorsal side. The frequency was significantly higher on the trunk than on the head and neck (P = 0.026). Our findings provide useful information for giving attention to the high possibility of diffuse PN on the dorsal side before progression in childhood and for future treatment in NF1

Epidemiological Analysis of Major Complications Requiring Medical Intervention in Patients with Neurofibromatosis 1

Neurofibromatosis 1 has various complications. To elucidate the frequency of neurofibromatosis 1-related major complications requiring medical intervention, a nationwide retrospective study was conducted of 3,530 patients with neurofibromatosis 1 registered from 2001 to 2014 in Japan. The ratio of certified patients requiring medical intervention (>stage 3) was 82%. Patients classified in the most severe grade experienced dermatological complications (71.8% of patients), neurological complications (38.1%) and bone complications (33.3%). In patients with dermatological manifestations, medical treatment was needed for cutaneous neurofibromas (58%), diffuse plexiform neurofibromas (31%) and malignant peripheral nerve sheath tumours (10%). Patients with neurological manifestations needed medical treatment mainly for brain tumours (53%) and intellectual disability (26%). Patients with bone manifestations needed medical treatment for pseudoarthrosis (9%), scoliosis (55%) and bone defects (16%). It is necessary for physicians to be aware of neurofibromatosis 1-related complications requiring medical intervention in order to provide appropriate care for patients with neurofibromatosis 1

Groundwater quality assessment for different uses using various water quality indices in semi-arid region of central Tunisia

The Hajeb Layoun-Jelma basin, located in the central Tunisia, is the principal source of water supply for Sidi Bouzid and Sfax region. The over-abstraction from this groundwater, since 1970, and the intensive agriculture activities led to the degradation of the water quantity and quality. The quality evaluation for this groundwater is very important tool for sustainable development and decision for water management. A total of 28 groundwater samples, from shallow, springs, and deep aquifers, were collected, storage and analyzed to evaluate its quality suitability for domestic and agriculture purposes using geographic information system and geochemical methods. For the both aquifers, the abundance of cations: Na > Mg > Ca > K, and of anions in the order: Cl > HCO3 > SO4. The dominant hydrochemical facies, for the shallow aquifer and springs, are Na-Cl and Ca-Mg-Cl; for the deep aquifer, the geochemical facies are Na-Cl, Ca-Mg-Cl, and Ca-Cl. The comparison of the major parameters and the chemical data with the World Health Organization standards and the national standards indicate that this groundwater is suitable for drinking, except in some samples, with high salinity concentrations. The water quality was assessed, for drinking uses, using "water quality index," "entropy," and "improved water quality index." The results mentioned that the improved water quality index is the best method which indicated that the poor water quality coincide with the Na-Cl water type. The entropy method and the water quality index present the optimistic methods. The irrigation suitability assessment was made using various parameters (SAR, TH, % Na, PI, MH, KR, EC). The results revealed that the majority of samples in Hajeb Layoun-Jelma basin are not appropriate for irrigation uses
