Energy is a major component of almost all economic, production, and service activities, and rapid population growth, urbanization and industrialization have led to ever growing demand for energy. Limited energy resources and increasingly evident environmental effects of fossil fuel consumption has led to a growing awareness about the importance of further use of renewable energy sources in the countries energy portfolio. Renewable hydrogen production is a convenient method for storage of unstable renewable energy sources such as wind and solar energy for use in other place or time. In this study, suitability of 25 cities located in Iran's western region for renewable hydrogen production are evaluated by multi-criteria decision making techniques including TOPSIS, VIKOR, ELECTRE, SAW, Fuzzy TOPSIS, and also hybrid ranking techniques. The choice of suitable location for the centralized renewable hydrogen production is associated with various technical, economic, social, geographic, and political criteria. This paper describes the criteria affecting the hydrogen production potential in the study region. Determined criteria are weighted with Shannon entropy method, and Angstrom model and wind power model are used to estimate respectively the solar and wind energy production potential in each city and each month. Assuming the use of proton exchange membrane electrolyzer for hydrogen production, the renewable hydrogen production potential of each city is then estimated based on the obtained wind and solar energy generation potentials. The rankings obtained with MCDMs show that Kermanshah is the best option for renewable hydrogen production, and evaluation of renewable hydrogen production capacities show that Gilangharb has the highest capacity among the studied cities.

The purpose of this research is to understand the levels of crisis and quality of life and the relationship between them. Data was collected from questionnaires completed by 384 middle-aged women between 40 and 59 years old. The sense of crisis was measured by a scale which was developed by Kim(1988) and modified by Oh(1999). The quality of life was measured by the scale which was developed by Noh(1988). The data was analyzed using the SPSS (Statistical Package for the Social Sciences) program and included: descriptive statistics, Pearson correlation, and stepwise regression. The results of this study were as follows: 1) In the sense of crisis scale, 'experiencing emptiness and powerlessness through my friends is the highest item($3.56{\pm}1.06$). 'Meaninglessness in daily living' factor's score is $3.16{\pm}0.76$ and another factor, 'concept of my life thus far' score is $2.89{\pm}0.74$. Then the former is higher than the latter. 2) In the quality of life, 'eat well now' is the highest item($3.60{\pm}0.93$). 'self-esteem' is the highest factor($3.37{\pm}0.62$) and 'emotional state' is the lowest factor($2.89{\pm}0.31$). 3) According to the correlation between factors of crisis and quality of life, there was a significant negative correlation between two factors of crisis and five factors of quality of life except emotional state. 4) According to linear regression, two factors of the sense of crisis showed the explanatory power of the quality of life with 31.6%. On the basis of above findings, the following is suggested; Crisis is not precipitated by special events and new accidents, but the normal emotional change phenomena process in the human life cycle. As a result, we should develop the nursing programs and education programs about crisis intervention for middle-aged women's health.

The Roh Moo-hyun Government of Korea with highest fierily establishes policy framework and measures to accomplish the goal of regionally balanced development. With the vision "constructing a county in which every region provides high quality of life with its own specificity" and basic strategy "self-sustained localization", the policy framework is geared to economic aspects of development rather than cultual or social aspects. Subsequently, policy measures are also focused on such economic tools as regional innovation system, strategic industry, or industrial cluster. This paper suggests that future policy of balance development should set clear definition of balanced development, be based on a though evaluation of the Bast policy measures, and draw several fresh ideas which match characteristics of each region. These policy directions should be given higher power of practice with efficient organizational support.

In this study, text mining and main path analysis (MPA) were applied to understand the origins and development paths of research areas that make up the mainstream of Korean studies. To this end, a quantitative analysis was attempted based on digital texts rather than the traditional humanities research methodology, and the main paths of Korean studies were extracted by collecting documents related to Korean studies including citation information using a citation database, and establishing a direct citation network. As a result of the main path analysis, two main path clusters (Korean ancient agricultural culture (history, culture, archeology) and Korean acquisition of English (linguistics)) were found in the key-route search for the Humanities field of Korean studies. In the field of Korean Studies Humanities and Social Sciences, four main path clusters were discovered: (1) Korea regional/spatial development, (2) Korean economic development (Economic aid/Soft power), (3) Korean industry (Political economics), and (4) population of Korea (Sex selection) & North Korean economy (Poverty, South-South cooperation).

This study tried to suggest the development of a writing education model for Christian Universities based on both Hobbs' media education model and Vanhoozer's media text analysis model. This model consists of 6 steps- Christian worldview establishment, access, analysis and evaluation, creation, reflection and social action. This was developed in order to be applied for the class "reading and writing" of liberal arts. Also, this is an appropriate model for media text writing education aiming at an alternative creation activity through a critical comprehension of the complex texts consisting of sounds, images, letters and so on. Furthermore, this is designed to train the capable persons having intelligence, character, and spirituality balanced, whom the education of Chrisitian universities aims at. Finally, this model pursues the student-friendly and amalgamative text writing appropriate for a new era and has an advantage to raise the power of various forms of letter writing which all the universities should stress as well.

Purpose: At a time when the distribution industry is dominated by capital and technology, win-win growth among businesses groups (BGs) in wholesale market is becoming a social issue. Therefore, through analysis of market growth, market concentration (MC) and market power (MP), we want to identify the structure of the wholesale market and the competitiveness of the BGs in terms of market share (MS), sales-profit ratio (SPR), and labor productivity (LP) to explore the possibility of win-win growth. Market situation: Wholesale and Retail sales ratio (W/S) continues to increase, which also means inefficiency in distribution channels or opportunities in wholesale markets. Wholesale sales have grown 8.3 percent annually over the past 15 years, while the number of companies and workers has declined since 2017, which is why some restructuring is believed to begin in the wholesale industry. In terms of MC and MP, the growth potential of SBG can be found in FCB, ARM, FBT and CME BTs. Methodology and data: Through ANOVA and Regression Analysis, the 2015 Economic Census Data of KOSTAT was analyzed. Results: The results of ANOVA show that statistically significant SBG has a larger MS than LBG. The SPR was not different among BGs. LP is higher for LBG than for other BGs. Regression results show that the employment weight (EW) and the company size (SC) have positive effects on the MS, but the company weight (CW) and employment size (SE) have negative effects. In the case of SPR, the CW is positive and the EW is negative. In addition, LP appears to be more positive as SC in the BGs is larger. Conclusions: Although there is sufficient potential for SBG in the wholesale market, there is a problem that needs to increase LP. Therefore, the SBG needs to restructure in terms of number of companies and SC to improve the efficiency of employment. In terms of MC and MP, the SBG looks for possibilities in FCB, ARM, FBT and CME BTs. In addition, SBG that seeks higher returns with human services rather than simple sales is found to be competitive in the HHG, MES and CME BTs.

This article examines how India's major colonial cities-Madras, Calcutta, Bombay (today, Chennai, Kolkata, Mumbai) and New Delhi- are described in India's history textbooks and analyzed them from the perspective of Indians. It is explained the major colonial cities as the process of making the cities and their political, social, economic and cultural changes, the separation between British and Indian, urban planning, colonial architectures built by British colonial power in Indian history textbooks. The viewpoint of its descriptions is featured by the coexistence of 'deprivation, exclusion, discrimination, resistance, challenge' and 'grant of opportunity, acceptation, absorption'. That is, this characteristic maintains a mutual confrontational and inseparable relation. And in a multi-layer, it enables to consider the inherent characteristics of a colonial city reflecting the British ruling ideology and the society within which the rulers and proprietors are forming without simplifying the cultural characteristics. It is clear that there was a resistance against the unreasonable discrimination and exclusion that had been suffered by the British colonial government as well.

Recently, Although particulate matter monitoring has been attracting attention as a result of social attention to the human impact of particulate matter, data suitable for the residential environment can not be obtained due to imbalances in the installation of monitoring stations and differences in topography. In this paper, we propose LoRa LPWA-based particulate matter measurement system which can make long distance wireless communication to measure particulate matter in residential environment. In the proposed system, it is possible to collect the data of the external environment which is difficult to construct the internet by utilizing LPWA which is a long distance wireless communication technology. When the proposed system is applied to the residential environment, it is expected to provide particulate matter monitoring information suitable for the residential environment.
