Line No. 4 was selected from local Champ a rice of Lord Egan, based on pure line selection method, during 1992 to 1995. The mean yield of this line was 6342 and 6829 kgha-l in two regions of Lord Egan in 1996 to 1997. The yield of this line was 700-1500 kgha-l more than that of Lord Egan local rice. Line 4 is more early maturing than the local rice with better marketability and quality. Amylase content of the grain is 21.4 24.6% and its white rice length is 6.1-6.3 mm. The grain are aweless, the color of pale a is brown furrow on straw, Panicle execution from pod of flay leaf is well, the plant height is 115-120 cm, and the growth period (days from planting to harvest) is 135-140 days. The panicle length is 21-24 cm, the seed number per panicle is 90-120 but its percentage of unfilled grains is less than local rice. Line 4 was introduced in Iran as KOHRANG cultivar in 1999.

Background & Objectives: Hypertension is one of the most prevalent and important risk factors of cardio-vascular diseases. The aim of this research was to determine relative factors on hypertension in KOHRANG.Methods: This survey was a population - based case - control study. The study population consisted of 415 patients with hypertension (cases) and 415 controls without any history of cardiovascular and or cerebrovascular diseases & hypertension. A systematic random sampling was used. The chi-square test and conditional logistic regression model was used and the data were analyzed by STATA.Results: Family history of hypertension, age over 60, no physical activity, bmi³30 were calculated as risk factors with odds ratio: 2.33 (95% CI 1.58-3.47), 2.01 (95% CI 1.24-2.67), 1.8 (95% CI 1.2-2.7), 1.66 (95% CI 1.32-2.07) respectively (p<0.05). Fish consumption, unsaturated fat consumption and literacy were considered as protective factors with an odds ratio: 0.516 (95% CI 0.35-0.69), 0.514 (95% CI 0.36-0.72), 0.28 (95% CI 0.17-0.45) respectively (p<0.01).Conclusions: The findings of this study highlight to plan appropriate health promotion programmes by health policy makers.

Mountain celery with scientific name of Kelussia odoratissima Mozaff is one of native medicinal plants of Iran that is an endangered species due to illegal removal. Present study was carried out to find the suitable treatment for stimulating germination of seeds this plant. A factorial experiment based on a completely randomized design with four replications was used. Stratification (4 ̊ C for 0, 4, and 8 weeks), 500 ppm solutions of Gibberellin (GA), Benzyl adenine (BA), Naphthalene acetic acid (NAA), Indole butyric acid (IBA) and combinations of these hormones as follows: (GA+IBA), (GA+ NAA), (GA+BA), (IBA+NAA), (IBA+BA), (NAA+BA), (GA+ IBA+NAA), (GA+ IBA+BA), (GA+NAA+BA), (IBA+NAA+BA), (GA+ IBA +NAA+BA) were the treatments. The results showed that Stratification or hormonal treatments alone increased germination parameters, however, 8 weeks stratification and GA were the most effective treatments. The highest germination percent and duration were obtained in GA, BA, GA+IBA+IBA and IBA after eight weeks of stratification at 4 ̊ C due to treatments interaction suggesting that seeds of this species has physiological dormancy. There was no synergic effect between hormonal treatments. The results showed that mountain celery had physiological dormancy and treatments with the greatest degree of success in breaking dormancy were GA, BA, GA+IBA+BA, BA and IBA under 8 weeks stratification.

This study aimed to investigate the situation of blended learning in the high school of KOHRANG city. For its implementation, a mixed research method was used. The research had two statistical populations. The first group was scientific experts, executive experts and the second group was school principals, teachers of the first and second secondary courses, and education experts from the Department of Education of KOHRANG. The method of selecting participants in the qualitative part was targeted (17 people) and in the quantitative part, stratified sampling was used (120 people). For data collection, semi-structured interviews were used in the qualitative part, and researcher-made questionnaires extracted from the interviews were used in the quantitative part. The validity of the questionnaire was done using face and content validity (0.79) and its reliability was also done using Cronbach's alpha coefficient for strengths of 0.79; Weaknesses 0.77; Opportunities were estimated at 0.82 and threats at 0.81. The findings showed that the most important point of strength was quick feedback to students and the most important point of weakness was the low level of electronic preparation of schools. The most important opportunity has been to achieve the goals of the education reform document as best as possible, and the most important threat has been to reduce the level of parental supervision over children. According to the findings of the research, the strengths outweigh the weaknesses and the opportunities outweigh the threats, so the proposed strategy of education is SO (Strength-Opportunity Strategy).

KOHRANGe sub-catchment is one of the main sources of North Karoun River. Climate variables, such as precipitation and temperature might have considerable impact on discharge of North Karoun River. To evaluate the impact of these variables, 27 years climate data were used. For this purpose, the mean of last ten years of 8 variables including, annual mean, max and min temperatures, number of snowy and rainy days, amount of annual rainfall, max daily rainfall intensity at KOHRANG station and discharge of Dezak hydrometric station over mean previous years were evaluated and analyzed using Mann-Candall and Sen’ s estimator methods. The above statistical methods showed that the mean annual temperature has increased by 1. 5 degrees Celsius compared to mean of previous years at the level of 95 percent confidence interval, but the max and min annual temperatures did not show a statistically significant trend. Although, the max daily rainfall intensity and the number of snowy and rainy days have reduced annually, but these tests did not show a statistically significant trend either. The above mentioned statistical tests confirmed decreasing trends in annual precipitation by 11 percent (155. 4 mm/year) and 19. 7 percent in discharge at Dezak hydrometric station.

In the absence of the twentieth century, some developed provinces have been encountered with many problems and challenges. Because, past plans were not successful in development of these areas such as poverty, employment, health, food security and environmental sustainability. These plans have not been successful in distributing the benefits of growth and development that leads to several problems for different areas, especially rural areas. One of the approaches that have recently been considered in most countries, Development of tourism in deprived areas that leads to expand tourism. The aim of this study refers to develop a model system according to specialist's viewpoints based on deep analysis of tourism obstacles in Saraghaseied village. It should be noted that the suggested model is adapted to extracted demographic information of Chaharmahal-Bakhtiari Province. This qualitative study was used grounded theory (one of the qualitative techniques) for data analysis. The statistical community of this research includes three categories: specialists of rural studies, local and foreign tourists, and cultural heritage experts. The purposed sampling (19 person by snowball method) via interviews -structured and semi-structured interviews are classified and analyzed. The results of the present study showed that Sraaghaseid tourist village has been faced to infrastructural problems, marketing, health and the other mentioned problems.

The nomadic lifestyle as the first social system of human society is accompanied by more difficulties than the rural and urban systems. Various strategies have been proposed by related planners and specialists in order to improve the quality of this way of life. One of the most important strategies is settlement of nomads. For this purpose, numerous nomadic centers (guidance and supportive) with different processes have been established for the settlement of volunteer nomads. According to the formation process of nomadic centers, the degree of acceptance and satisfaction of nomads from these centers is different. The purpose of the current research is to compare the formation process of nomadic centers and measure the acceptance and satisfaction of nomads in KOHRANG area (Chaharmahal and Bakhtiari). This research is descriptive-analytical and the data collection method is documentary and field with a survey approach. The statistical population of the research includes settled nomadic households in the nomadic settlement centers of KOHRANG district. The results show that the participation of the nomads in the implementation of the nomad settlement plan was more in the supportive centers than in the guidance centers. In terms of satisfaction, according to the results of one-sample T test, the level of satisfaction and acceptance of the nomads from the supportive centers (3.95) has been evaluated more than the guidance centers (3.26).

The most basic form of studying the stability of nomadic systems in the new structure of the network society is the way of their spatial interactions. In this direction, regional planning and dynamic networks with the analysis of the indicators of spatial flows in the form of categorization under the conceptual relationships of the elements of spatial social networks will lead to the sustainability of the productive group activity of nomadic activists in the ecosystem pairs. . The current research is based on the applied purpose and descriptive analytical research method. The required data has been obtained by documentary method. The study area of Shurab Tengzai district and the statistical population are the summer and Qashlagi systems of the Babadi tribe bio-ecosystem. Weighting of the research indicators was done using the F'ANP model process and data analysis was done using the VIKOR multi-criteria decision making method. Cluster analysis method and ARC GIS software were used to classify the studied systems in terms of stability levels, and linear regression was used to analyze the factors affecting stability. The results of the research showed that out of 65 studied systems, ten systems are at the level of "relatively" stable interactions inside and outside the realm of the ecosystem in terms of access and availability of facilities (mobile education, fuel, electricity, internet network, road network), natural resources and artificially, 15 systems are in the category of low stability interactions, and 40 systems are in the category of unstable interactions.
