During the last two decades, sports medicine is increased and experienced a stage of rapid development, especially in such areas as the study of strength, endurance, sports injuries and psychology. Study of ongoing changes when performing exercises at the cellular and molecular levels led to the development of new areas in the sports science as known as genetic medicine that deals with the genetic basis of athletic phenotype. Around 66 % of the variance in athlete status is explained by genetic factors, the remaining variance is due to other factors such as training, nutrition, equipment, motivation, sleeping and epigenetics. Over the last two decades, at least 155 genetic markers (located in almost all chromosomes and mtDNA) were associated with elite athlete status (93 genetic markers with endurance and 62 markers with power/force). The number of identified genetic markers associated with sports activity, grew at a rate exponentially: in 1997 – 5 genes; in 2000 – 24 genes; in 2004 – 101 genes. During the last 19 years, found that at least 120 of genetic markers associated with elite athlete status (77 genetic markers related to endurance and 43 genetic marker settings capacity/power). Of the polymorphisms associated with sports endurance, the angiotensin-converting enzyme (ACE) and alpha actinin-3 (ACTN3) polymorphisms have been the most frequently studied, and meta-analyses have confirmed the associations. ACTN3 is absent in approximately 18% of European population, 25-29% of Japanese population and overall about 1.5 billion people in all countries. Therefore, to date, available genetic tests based on small sample sizes and the selected analytical methodology can lead to erroneous associations and to reassess the size of the effect, and of course, the use of such limited data does not allow us to predict athletic ability with high accuracy.

An adaptive algorithm for compressing the color images is proposed. This technique uses a combination of simple and computationally easy operations. The two main steps consist of decomposition of data and data compression. The result is a practical scheme that achieves good compression while providing fast decompression. The approach has performance comparable to and often better than, existing architecture. This paper gives the overview of an adaptive lossless compression scheme. This scheme uses a new technique to predict a pixel by matching neighboring pixel, an adaptive color difference estimation scheme to remove the color spectral redundancy while handling red and blue samples and an adaptive codeword generation technique to encode the prediction residues. The technique lossless image compression plays an important role in image transmission and storage for high quality. At present, both the compression ratio and processing speed should be considered in a real time multimedia system. Lossless compression algorithm is used for this technique. A low Complexity predictive model is proposed using the correlation of pixels and color components. Also a color space transform is used and good decoration is obtained in our algorithm. The compared experimental results have shown that our algorithm has a noticeably better performance than traditional algorithms. Contribution/ Originality
Sunlight is a limitless form of renewable and clean energy which is amply accessible. Economic consumption of solar energy can boundlessly fulfil the energy demand.

The reinforcement of corporate governance in Japan is one of the pillars of Japan’s growth strategy which companies have to regain "the power to earn". In this respect, the influence of the introduction of outside director on performance of Japanese companies still remains controversial. This research reached one conclusion by introducing a new viewpoint. Especially, we examine how outside director is associated with earnings persistence in Japanese listed companies. Many prior researches agree that company profitability tend to move to the average over time. Earnings persistence is a concept of time series tendency of earnings. Prior research developed some empirical measurements of earnings persistence. If outside director has positive impact on the profitability, then earnings persistence of companies with higher proportion of outside director are higher than that of companies with lower proportion of outside director. Our data used for this study are from Nikkei Economic Electronic Databank System (NIKKEI NEEDS) by Nikkei Media Marketing, Inc. NIKKEI NEEDS has data for all listed companies on stock markets of Japan. We focus on all companies listed on the first or second section of the Tokyo Stock Exchange, and select 13,376 firm-years in the period from 2003 to 2014. We test the effect of outside directors on performance using the empirical model used by many accounting studies. Our results indicate that outside director has positive impact on the profitability in critical situations, while he or she has little positive and negative impact on the profitability normal situations. We conclude that impact of outside director on corporate performance is narrow in Japan. Contribution/ Originality
The paper's primary contribution is finding that outside director has positive impact on the profitability in critical situations, while he or she has little positive and negative impact on the profitability normal situations. We conclude that impact of outside director on corporate performance is narrow in Japan.
Recently, as an interest in strongly contagious infectious diseases such as MERS increases, proper infectious disease management systems using ICT have been discussed. Particularly in Korea, the process-centered measures on the basis of ICT infrastructure and the internet of things are under discussion. However, studies on these are very rare. This study aims to propose an infectious disease management system in which ICT is incorporated into each process of the spread of infectious diseases. The scope of analysis is limited to the infectious diseases that flow from a country into the other country through air transportation. The process encompassing from the entry to the eradication of an infectious disease is classified into 5 stages (airport, transportation of patients, medical institutions, self-isolation, and waste disposal), and a journey map is suggested. Subsequently, an efficient infectious disease management system in which ICT is introduced to each stage is proposed. This study has significance in that it has unprecedentedly analyzed the entire spreading process of infectious disease from the process-centered perspective, and is expected to suggest a new convergence direction of ICT. Contribution/ Originality
This study contributes to construct the effective infectious disease management system and provide a new direction for the convergence of ICT in future.
As the number of services that use spectrum such as IoT and commercial drones are increasing rapidly every year, it has become very important to efficiently allocate the spectrum resources. Advanced countries are shifting towards open spectrum system which provides the suitable environment for using radio wave and pursue new technological service innovation. Global companies such as Amazon, DHL, and Google are already investing a lot of resources into the commercial drone technology and made significant contributions. Korea’s commercial drone industry, on the other hand, had limited growth because commercial drones are strictly regulated. In this respect, the purpose of this paper is to derive a policy measure for open spectrum to foster the Korean commercial drone industry. The research was conducted as follows: (i) Literature review of open spectrum and commercial drone industry and (ii) Expert interview on key issues. Following implications have been drawn from case studies in other countries and the expert interview: (i) Establishing data-based open spectrum management system, (ii) Designing a plan to develop new service using spectrum in middle and long term, (iii) Selecting spectrum band width exclusive for open spectrum and drone for international compatibility (iv) The need for a unified agency which can manage and regulate drone industry. These results imply that in order to foster the commercial drone industry, it needs a collaboration with the field of spectrum, and an international standard. The contribution of this study is to provide a strategic guideline for the countries that are in the early stage of developing commercial drone industry, and establish policy and legal guidelines to help foster commercial drone industry. Contribution/ Originality

This study uses an expert interview to investigate key issues.
Manufacturing System has been evolved over the years to accommodate major design variations. To respond to these high frequency variations and to stay competitive, there is a need of having such type of manufacturing system that could cope with market trends and design changes efficiently. Product’s design and its manufacturing capabilities are closely related, thus the manufacturing system should be customized to cater all the design changes with suitable manufacturing capabilities. Reconfigurable Manufacturing system has been recommended for the turbulent market conditions because of its flexible and changeable nature. This research work is based on the co-generated model in which optimal machine configurations are generated through the application of optimization technique. Based on these configurations, system is tested for reconfiguration in case of production changeovers. Considering the relevant change drivers the degree of reconfigurability in any case of application can be achieved through proposed algorithm. A case study has been presented to illustrate the application of proposed model based on the technological constraints. Contribution/ Originality
This study contributes in the existing literature of reconfiguration in a manufacturing system. Considering the parameters mentioned in eq.1 makes this approach generic, reliable and cost effective. Selection of operation and its sequence has given better flexibility and scalability through the application of MOGA. Actual resources (machining and assembly setups) can be obtained using this approach by measuring extent of reconfiguration for production changeovers.
The present study was conducted to evaluate the nutritional profile, phytochemical screening, antimicrobial and antioxidant activities of aqueous and acetonic extract of Withania coagulans by standard chemical analysis methods. Proximate analysis revealed that aqueous extract of W. coagulans is a rich source of soluble solids (16.1 ± 1.5 %), fiber (15.5 ± 0.1 %), pH (11.5 ± 0.19 %), ash (11.2 ± 0.2 %), sugar (9.7 ± 0.1 %) and ascorbic acid (9.7 ± 0.1 mg/100ml). Phytochemicals detected were flavonoids, glycosides, carbohydrate & sugar, phenolic compounds, proteins & amino acids, tannins, gum and mucilage while phytosterols were absent. The antifungal and antibacterial activities of plant extract was determined against ten pathogenic bacterial strains (Escherichia coli,Bacilluscereus, Staphylococcus aureus,Clostridium, Escherichia coli (Human), Bacillus subtilius, Xanthomonas, Salmonella typhi,Salmonella heidelberg and Klebsiella pneumonia) and five fungal strains (Penicillium, Aspergillus niger, Alternaria alternata, Entomola and Aspergillus flavus) using the agar well diffusion method. The acetonic extract of W. coagulans indicated highest antibacterial activity (12 mm) against Clostridium and Salmonella heidelberg and lowest action (5 mm) against E. coli (Human.). Highest antifungal activity (10 mm) was recorded against Alternaria alternata and Penicillium while Aspergillus niger showed lowest zone of inhibition (6 mm). Streptomycin was used as a control. The acetonic extract of W. coagulans exhibited highest free radical [(1, 1-diphenyl-2-picryl hydrazyl (DPPH)]) scavenging activity (72 %) at concentration of 30 mg/ml, with an IC50 value (18µg/ml) as compared to control (4µg/ml). The presence of bioactive compounds, nutrients and biochemical screening indicated that the seeds of W. coagulans can serve as a potential source of useful drugs for the treatment of various pathologies.

An increased inter-recti distance is a common problem in late pregnancy and during postpartum period. According to researches diastasis recti abdominis’ occurs in 35-60% of the cases. There are only assumptions about the risk factors, treatment and consequences. The aim of this study was to determine the effect of the treatment in the postpartum period using a single case study. A 33-year-old woman, six weeks after her first delivery, was recruited to the research. She complained about abdominal muscle weakness and low back pain. The patient got a three-months-long physical therapy in which the strengthening of the transverse abdominal muscles was primary. After the intervention the pathological inter-recti distance achieved the normal range almost at each reference point. This study found that the inter-recti distance was reduced when isometric contraction of the transverse abdominal muscle was performed. This suggests that this type of exercise could be effective in treating the postpartum diastasis recti and preventing the possible sequelae. Contribution/ Originality
This study contributes in the existing literature with the observations of a single case treatment. It is unique because nobody in Hungary has investigated diastasis recti abdominis yet, in consequence a new country appeared which can be active in researches in obstetric and gynecologic physiotherapy.
Tourism in Cambodia has grown remarkably since the early 2000’s; the influx of international travelers meant that tourist industry (TI) frontline employees have needed top-level English communication ability. Since background data in Cambodia has been lacking, the author wanted to verify the role of English communication ability (ECA) in TI employees in Siem Reap city to fill this gap. During four surveys over five years, the author collected background as well as ECA data. To more accurately measure ECA numerically as a means for other researchers to conduct further studies, the author designed an assessment test loosely based on the CEFR. In statistical analysis of income with English variables, high positive correlations were found in English communication ability, years and hours of English education, and monthly expenditure for English learning. Therefore, it can be said that there is a significant relationship between ECA, better employment, and higher incomes in TI employees there. This scale could be profitably used via the Internet to conduct similar research in similar situations. Contribution/ Originality
This study contributes in the existing literature by providing a new way of examining the importance of English ability toward tourism employment and income. It is also one of the very few studies which have collected socioeconomic and English background data much of which has never been collected before.
Increased attention has been devoted to the issue of pursuit of personal excellence in the higher education in Taiwan in order to enhance the teaching quality and increase students’ competition. While the government has devoted considerable efforts and funding to education institutions through different academic excellence plans, there has been relatively little discussion of pursuit of excellence among student population, nor have there been any curriculum or training programs designed for students to improve their personal excellence. Thus, the present study aims to fill the research gap by designing a training program for the personal excellence of undergraduate tourism students in Taiwan. Grey Relational Analysis (GRA), a multi-criteria decision analysis method, is conducted to prioritize personal excellence training needs for tourism students. The training programs are then developed with a focus on enhancing weak areas of personal excellence competence for tourism students. It is hoped that the results can give students an advantage in entering and staying in their chosen industry, leading to success in both their professional and personal lives. Contribution/ Originality
This study contributes in the existing literature to examine Taiwanese undergraduate tourism students’ self-reported strengths and weaknesses in personal excellence abilities, with the ultimate goal of developing training programs to strengthen their personal excellence competencies and thereby better equip them for success in the professional realm.

The continuous adoption of trade openness policies and floating exchange rates regime by developing countries exposed them to speculative pressures. It makes exchange rate shocks easily transferred to domestic consumer prices. That makes tremendous impacts on the domestic consumer price inflation. This paper thus examines the response of domestic consumer prices to exchange rate changes otherwise known as ‘Exchange rate pass-through’. The paper uses vector error correction (VECM) model to examine the relationship. A quarterly time series data for a period ranging from 1986Q1 to 2013Q4 for Nigeria was used. The study found a substantial but incomplete and slow pass-through of exchange rate changes to domestic prices. Contribution/ Originality
This study contributes in the existing literature by estimating the ERPT using Nigerian data as there are very few studies on ERPT for developing countries and particularly Nigeria. This study uses VECM model against the SVAR model used by other studies.
The survey analyzed rural youths participation in family farming in Benue State, Nigeria. Structured questionnaire/interview schedule were used in collecting data for the study. Frequency, percentage, mean score, standard deviation, factor analysis and binary logistic regression model were used for data analysis. Findings revealed that about 75.00% of the respondents were males, single (63.70%), had formal education (98.90%), having farming as a major occupation (92.40%). Major roles performed by the respondents in family farming include site selection (M = 2.70), harvesting of crops (M = 2.61), applying fertilizer to crops (M = 2.55), clearing of farm land (M = 2.54), soil tillage (M = 2.51), among others. These were further classified as land preparation, management and technical roles. The study recommends that rural youths should be encouraged to remain in agriculture by ensuring that they are provided with improved technologies for greater productivity. Basic amenities such as electricity, pipe borne water, good roads, etc should be made available in rural areas where they reside to prevent rural-urban youth migration and sustain agriculture. Contribution/ Originality
This study documents that rural youths are involved in family farming for household food security. They participate actively in family farming playing key roles in land preparation, management and technical areas of crop and livestock production. Efforts of these youths should be sustained for them to remain in family farming.
Indoor air pollution due to combusting biomass fuels is a serious problem in developing countries and the impact to a greater extent is less known from burning mosquito coils. As malaria is a major killer in developing countries, the use of mosquito repellants would continue to be used in millions of homes across the continent of Africa. Hence this pilot study was conducted to assess emission levels of nitrogen dioxide (NO2); sulphur dioxide (SO2) and carbon monoxide (CO) during the burning of six different products of mosquito coils that are sold in Sierra Leone. One hour emission value was recorded for each product during the burning period. Result revealed that one hour SO2 concentrations range from not detected to 47 ppb and that for CO range from 16 ppm to 19 ppm for the different products. Evidence of high peak values was observed for both SO2 and CO for the different products which is clearly a public health concern. This pilot study demonstrated that burning mosquito coils in less ventilated rooms where the primary focus is to eliminate mosquitoes is an environmental health risk in Sierra Leone. Contribution/ Originality
This study is the first that has provided informed information to relevant stakeholders in Sierra Leone on the dangers of combusting mosquito repellants in less ventilated areas by measuring the emission levels of gases deemed dangerous to public health.
A fuzzy transportation problem (FTP) includes cost, supply and demand of transportation problems. Its numbers are fuzzy numbers. Fuzzy transportation problem works to reduce transportation cost of some commodities through a capacitate network. Present research paper points out a technique with an alpha cut, optimal solution for solving transportation problem. We suggest a technique to find the fuzzy optimal solution on scales of transportation problem and propose a new hexagonal representation of fuzzy numbers. In general, the comparison of balanced fuzzy transportation problem (BFTP) and unbalanced fuzzy transportation problem (UFTP) shows that the optimal transportation cost of UFTP is less than BFTP. Contribution/ Originality
This study contributes in networking for transportation. This study uses new estimation methodology. This study originates optimal solution and comparison between BFTP and UFTP. This study investigated comparatively. This paper contributes the first logical analysis that is minimizes or maximizes objective solution is an optimal solution in hexagonal fuzzy numbers.
Potholes, debris, sunken manhole covers and others are common street safety hazards which drivers experience daily as they bump into them unexpectedly while driving. Pavement roughness is usually evaluated based on the International Roughness Index (IRI), which is considered the most prevalent metric. In this work, IRI values are collected by using a smartphone, with built-in vibration sensor, placed on the car’s dashboard while driving around the city. The classification process of IRI values is primarily performed using an Artificial Neural Network (ANN) for the detection of diverse predefined street safety hazards. The designed ANN is a backpropagation pattern classifier, that must be trained to yield either a detected “disorder” area of the road or “normal” area based on the IRI data collected. The process of preparing the training and testing datasets involves a number of pre-processing operations. The IRI values are pre-processed in order to extract the most effective features. Then the network is trained with the normalized feature set by using supervised learning method. The performance of the designed network is compared to a similar works in the literature. Results show that the designed network can successfully classify the street conditions by using IRI values with a success rate that outperforms the classification rates obtained by other works.
