Revitalization of Fishing Village Tourism
Fishing villages and oceans offer various resources and include excellent natural environments and unique cultures that can make such villages attractive spaces to meet the health, culture, and environmental needs of individuals. However, as society has developed and the environment has changed, the catch, which is the major source of income in fishing villages, has declined significantly worldwide, making it difficult to address regional economic issues. Fishing villages that have lost their ability to survive are gradually facing extinction, and there are real problems linked to the survival of fishing communities. Rural areas, in a similar manner to fishing villages, are incorporating tourism in regional development in an attempt to solve the crisis of agriculture, which has itself lost the ability to support entire villages. As a result, tourism has come to be recognized as a representative means of revitalizing rural areas.

Poly (Butylene Succinate) and PBS Copolyesters Degradation
The impact of plastics on the environment can be mitigated by employing biobased and/or biodegradable materials (i.e., bioplastics) instead of the traditional “commodities”. Poly (butylene succinate) (PBS) emerges as one of the most promising alternatives due to its good mechanical, thermal, and barrier properties, making it suitable for use in a wide range of applications. Nevertheless, less information regarding PBS biodegradation is available, as research is still ongoing. PBS degradation methods include hydrolytic degradation, enzymatic degradation, and biodegradation in environmental conditions, such as burial, activated sludge, and compost.

Panj Takht
A takht, or taḵẖata (Punjabi: ਤਖ਼ਤ) literally means a throne or seat of authority and is a spiritual and temporal centre of Sikhism. There are five Takhts, which are five gurudwaras that have a very special significance for the Sikh community. The first and the most important was established by Guru Hargobind in 1609, 'Akal Takht' (the Throne of the Timeless God) and is just opposite the gate of Harmandir Sahib – The Golden Temple, Amritsar. While the Harmandir Sahib, or Golden Temple, represents Sikh spiritual guidance, the Akal Takht symbolizes the dispensing of justice and temporal activity. It is the highest seat of temporal authority of the Khalsa and the seat of the Sikh religion's earthly authority. There, the Guru held his court and decided matters of military strategy and political policy. Later on, the Sikh Nation (Sarbat Khalsa) took decisions here on matters of peace and war and settled disputes between the various Sikh groups. The Sarangi singers sung the ballads of the Sikh Gurus and warriors at the place and robes of honour (saropas) were awarded to persons who rendered distinguished services of the community of men in general. In December 2010, the Deccan Odyssey train, taken on charter from Government of Maharashtra, started with the aim to have a journey across four Sikh takhts, with a flight by devout and sightseers to the fifth takht (Takht Sri Patna Sahib). A special train named Panj Takht Special train for the pilgrimage of five Sikh takhts, was flagged off on 16 February 2014.

Genetic Use Restriction Technologies
Genetic use restriction technologies (GURTs), developed to secure return on investments through protection of plant varieties, are among the most controversial and opposed genetic engineering biotechnologies as they are perceived as a tool to force farmers to depend on multinational corporations’ seed monopolies.  This led to a de facto global moratorium on this technology, which is still far from being withdrawn.

Hydroxycinnamic Acids
Hydroxycinnamic acids (HCAs) are important natural phenolic compounds present in high concentrations in our food products. Dietary intake and nutritional importance of HCAs is briefly described along with their pharmacokinetic properties, which have a high impact on HCAs to reach the target tissue in order to exert their biological activities. A range of health beneficial effects were observed for HCAs and in recent years, also for their metabolites formed in gastrointestinal tract, liver and kidneys. Therefore, metabolism is of high importance since HCAs’ metabolites could retain, enhance or lose the biological activity of corresponding parental HCAs. The biological activities and health benefits of HCAs' metabolites are also briefly reviewed.

Triticum Dicoccum
Emmer wheat or hulled wheat is a type of awned wheat. Emmer is a tetraploid (2n = 4x = 28 chromosomes). The domesticated types are Triticum turgidum subsp. dicoccum and Triticum turgidum conv. durum. The wild plant is called Triticum turgidum subsp. dicoccoides. The principal difference between the wild and the domestic is that the ripened seed head of the wild plant shatters and scatters the seed onto the ground, while in the domesticated emmer the seed head remains intact, thus making it easier for humans to harvest the grain. Along with einkorn wheat, emmer was one of the first crops domesticated in the Near East. It was widely cultivated in the ancient world, but is now a relict crop in mountainous regions of Europe and Asia. Emmer is considered a type of farro food especially in Italy.

Moringa as Natural Feed Supplement
Application of natural herbs with a view to enhancing production performance and health status has created an important demand in poultry production. With the increasing concerns on this issue, greater attention paid to alternatives to antibiotics for organic meat and egg production has led to a great demand. This study was conducted with view to assessing the possible role of M. oleifera as a natural feed supplement in poultry ration. Various scientific findings and published research articles were considered concerning issues including the study background, objectives, major findings, and conclusions of the review. M oleifera is known as a miracle tree because of its wealthy resource of various nutrients with high biological values. M. oleifera has been used as a growth promoter, immune enhancer, antioxidant, and has a hypo-cholesterol e ect on chickens. It has both nutritional and therapeutic values. However, there is still much confusion in past published articles involving the major roles of M. oleifera in production performance and health status of chickens. Taking this into account, the present study highlights an outline of the experimental uses of M. oleifera on growth performance, egg production performance, egg quality, and health status in broilers and laying hens justified with the past findings to the present. The knowledge gaps from the past studies are considered, and the feasibility of M. oleifera in poultry ration is suggested. The findings have motivated further study on M. oleifera to find out the most active ingredients and their optimal doses in both broiler and laying hen rations. Finally, the present study highlights that supplementation of M. oleifera may play a role in the immunity, sound health, and production performance in poultry.

Theory of Planned Behavior in Energy-Saving Behaviors
People with physical impairments can help solve energy problems by participating in diverse energy-saving behaviors, such as switching off lights or turning off an air conditioner when not in use; however, they may struggle to participate in some behaviors due to mobility impairments. An energy-saving behavior is an individual action that aims to reduce energy consumption and the negative environmental impacts of energy consumption and production. The theory of planned behavior (TPB), which was proposed by Ajzen in 1985, is an extension of the theory of reasoned action (TRA).
