A health index was proposed that evaluates personal health state from both measured physiological variables and survey questions. Four health indices were defined such as cardiovascular index, stress index, obesity index, and management index. The total health index was calculated by summing these four health indices. Physiological variables such as blood pressure, heart rate variability(HRV), accelerated photoplethysmograph(APG), and body fat percentage were non-invasively measured and a survey questionnaire that asks personal health state, exercise intensity, and food preference was developed. The suggested health index was applied to thirty eight persons including 30 patients and 8 normal persons with an average age of 51.8. The average health index was estimated to be 75.1 out of 100 points. Young age group(below 50) and men group showed higher health indices than the aged(over 50) and women groups. The correlation coefficient between the cardiovascular index and stress index was found to be 0.513, which means stress is related to cardiovascular health state. The correlation coefficient between the measurements and survey questions was 0.385 for the cardiovascular index. It was as low as 0.182 for the stress index. More case studies may improve correlations between measurements and survey questions, and then, the current health index system may develop as an effective tool to evaluate personal health state.

This study aims to find out factors to affect forest area of public sector such as state forest and estimate optimum area of state forest in Korea. This study was carried out with the rate of public forest and public forest per capita as dependent variables and 15 independent variables to the 35 countries in OECD countries using analysis of linear regression. From research, optimum area of the public forests of Korea was estimated from to minimum 2,136,000 hectares to maximum 2,667,000 hectares, based on OECD countries. The public forest areas of Korea were 1,984,000 hectares in 2010. To reach the average level of OECD countries, it is required that public forest areas of Korea are expended from minimum 152,000 hectares to maximum 683,000 hectares. It is hard to expect that enhancing the areas of public forest in Korea through expanding local government owned forest areas. Therefore, it required that state forest areas are expanded by Korea government.

The article aims at studying the institution of human rights in an ever-evolving world in the context of the interdisciplinary approach. The main scientific method was deduction that allowed examining the specific interdisciplinary approach in relation to the institution of human rights on the global scale. To solve the issue set, it is necessary to study legal foundations and features of the interdisciplinary approach to the institution of human rights in the modern world. The article proves there is no theoretical anthropological understanding of the institution of human rights. It has been concluded that the appeal to anthropological jurisprudence requires the identification of the initial theoretical and methodological principles, parameters and axioms of cognition, the integration of a person into the subject field of legal science, linking jurisprudence with the chosen external environment (philosophy, sociology, theology, etc.), predetermining the existence (understanding) of a person, causing qualitative differences and the structure of subject-methodological phenomena. In addition to the identification of such hypotheses, prerequisites and axioms, the basic method (principle) of cognition and its heuristic potential are also being searched (defined). The terminological designation of the formed subject-methodological phenomenon (legal anthropology, anthropology of law, anthropological approach, etc.) reveals its role in the system of interdisciplinary relations of legal science.

Texas has recently emerged as a phenomenal industrial destination, which attracts headquarters, production facilities, and/or regional centers of global corporations including Tesla and Samsung. Known as "Texit", this trend of corporate investment to Texas has concentrated in highly developed industrial clusters (such as Dallas-Fort Worth, Houston, Austin, and San Antonio) since the early 2000s. Against this background, this paper examines sectoral and geographical characteristics of those clusters, and investigates associated state initiatives that have been introduced and implemented. As a result, key policy measures in the state are found to be aligned to free-market liberalism, diversified incentives, and regional specialization. Unlike Silicon Valley where Bohemian liberalism engendered vibrant entrepreneurship and innovative start-up formation, it is the strong state government that leads industrial cluster upgrading in Texas, while successfully harnessing lower income taxes and deregulation, affordable land and infrastructure, and quality higher education and human capital as regional assets for attracting inward investment.

The relevance of the published study lies in the fact that since the introduction of the first Global Distribution System, new information and communication technologies have constantly been changing the tourism industry. In the context of a current digital environment, travel agencies can't avoid participating in digital transformation processes aimed at rethinking operational models, skills, and organisational structures in the regions. This publication aims to present and provide a critical overview of digitalisation processes in tourism development in the regions of the Russian Federation, as well as to reflect on the challenges to the widespread digitalisation processes in the regional tourism sector. The subject of research is digitalisation processes, as they radically transform the modern tourism industry, in the regions as well. The pragmatic research paradigm was considered the most appropriate for the study of tourism digitalisation processes in the regions, as it does not require the selection of a specific theoretical basis for data collection. The pragmatic approach forms an alternative to classical theoretical approaches and serves as a particular type of grounded theory, combining both inductive and deductive methods. No software was used for the inductive part of the analysis. The deductive part was conducted using the qualitative data analysis software Nvivo 11. Given the wide diversity of interested parties in the regional tourism digital area, a stratified purposive sampling method was preferred due to its ability to adequately represent the full picture of the phenomenon under study. The selection and stratum criteria were chosen to maximise the representation of different perspectives in the regional tourism digital area. The novelty of the study is due to the digitalisation processes, with an implication of new needs, while opening up promising opportunities for more productive tourism business in the regions of the Russian Federation. Currently, e-tourism in the Russian Federation has become a subject of lively debate among scholars and practitioners. However, the involvement of advanced digitalisation technologies in the field of information processes in the regions of the Russian Federation is of a very sporadic character.

Fossil energy sources are limited in their sustainable use and expansion due to global warming caused by carbon dioxide emissions. Hydrogen is considered as a promising alternative to traditional fossil fuels. To ensure the stable long-term storage, it is necessary to accurately predict its thermodynamic properties at cryogenic temperatures. Therefore, this study aimed to investigate thermodynamic properties, such as saturated vapor pressure and density, enthalpy, and entropy of liquid and gas, using cubic equations of state that demonstrate relatively simple relationships. Among the three types of equations of state (Redlich-Kwong (RK), Soave-Redlich-Kwong (SRK), and Peng-Robinson (PR)), the SRK model exhibited relatively accurate prediction results for various physical properties.

In modern society, culture is an important factor to form a country's image and identity and a representative content to generate revenue. Culture is a keyword to design life in the 21st century and has become competitiveness between countries. As a cultural content with international competitiveness, this study performed textile design development with the use of relics from the Tomb of King Muryeong, which is the tumulus of King Muryeong who was the 25th king of Baekje among Korean history. The developed design could be applied to the production of various fashion cultural products such as clothes, scarf, neck-tie, and bag. The process for the design development was carried out as follows: As a first step, this study found basis as a cultural content with a global sense that could form the historical value of the Tomb of King Muryeong and gain global sympathy of people all over the world through literature reviews. As a second step, this study examined the current state that traditional Korean elements were used as a fashion cultural products. As a third step, this study analyzed the current state and problems of fashion cultural products using relics from the Tomb of King Muryeong through field survey. As a final step, this study planned the concept of design with the use of diadem ornaments, earring, sword, stone guardian animal, and bricks with lotus-flower design from the tomb of King Muryeong. And these developed 6 textile designs could be applied to the production of various fashion cultural products.

Under partial shading conditions (PSCs), multiple maximums may be exhibited on the P-U curve of string inverter photovoltaic (PV) systems. Under such conditions, heuristic methods are invalid for extracting a global maximum power point (GMPP); intelligent algorithms are time-consuming; and model-based methods are complex and costly. To overcome these shortcomings, a novel hybrid MPPT (MPF-IP&O) based on a model-based peak forecasting (MPF) method and an improved perturbation and observation (IP&O) method is proposed. The MPF considers the influence of temperature and does not require solar radiation measurements. In addition, it can forecast all of the peak values of the PV string without complex computation under PSCs, and it can determine the candidate GMPP after a comparison. Hence, the MPF narrows the searching range tremendously and accelerates the convergence to the GMPP. Additionally, the IP&O with a successive approximation strategy searches for the real GMPP in the neighborhood of the candidate one, which can significantly enhance the tracking efficiency. Finally, simulation and experiment results show that the proposed method has a higher tracking speed and accuracy than the perturbation and observation (P&O) and particle swarm optimization (PSO) methods under PSCs.

The study has applied the four stage "Model of State Behavior in Crisis" to trace the post 9/11 crisis foreign policy decision making process in Pakistan. It argues that ominous attacks on the United States by al-Qaeda and subsequent declaration of President Bush to fight against terrorism transformed the global and regional politico-security dimensions at t1 stage. Being a neighboring country, Pakistan's support was inevitable in the war on terror and Washington applied coercive diplomacy to win the cooperation from Islamabad. Consequently, in case of decline to accept American demands, Pakistan perceived threat to basic values/objectives of the country and simultaneous time pressure amplified the psychological stress in decision makers at t2 stage. Therefore, the decisional forum was setup at t3 stage and Pakistan decided to join the United States at t4 stage, which defused the foreign policy crisis.

Islands are vulnerable to outer influences due to their small size and isolation. Tourism often becomes an important development focus because of their unique culture and nature. Jeju-do, as well as other islands, has experienced such development mostly led by central government, and the regional change was understood as the outcome of global influences without much concern with the local response or strategy. Thus, vulnerability has been the key theme in island development studies. This paper examines the current state of island development as an outcome of locals' alternating strategy in which the islanders accept the central government's plan, but express their demands to modify them. It is reflected in the electoral preference for ruling or oppositional parties, local movements against central government's development plans, and the spatial organization of tourism sites from a few growth centers to more dispersed, balanced development. These suggest that the current state of island development is not derived from unidirectional global forces, even if islands are peripheral. Rather, it is the outcome of an alternating strategy of Jeju locals accepting the central government development plans while managing them for local benefits.
