Innovations that imposed the fastest on people's lives following the development of technology at an unpredictable speed are more likely to take place in the field of communication. Just 20 years ago when few people had mobile phones, today's even young children have smartphones or tablets. These devices greatly meet people's communication and entertainment needs through wireless internet. Wireless internet connection has sprawled over the city from indoors to outdoors, from privacy to public domain, and it has been integrated into the square and parks of the cities and opened for people's use. One of the first applications of free wireless internet service in the open and green areas of our country is the Pasaport Internet Park in Izmir. Some criteria have been established as a result of research conducted by the University of Seattle on the design and equipment of these spaces, also known as the iPark in the USA. In this study, the design and equipment of the internet park in Pasaport was discussed in terms of its relevance with the criteria determined by Guangyan Wang’s master thesis from Illinois University and Shafi al-Shafi and Vishanth Weerakkody’s article from Brunel University; the positive and negative aspects were discussed. At the end of the research, some mistakes about spatial organization and planting design have been determined and some solutions for those problems have been offered.

Nowadays, indoor plants that are part of the commercial sector commonly be in use in living quarters for estetical and functional features. Especially the areas such as houses, offices, shopping centers are the places where we often see indoor plants. Indoor plants, beside having estethical characteristics such as making living spaces more attractive and adding color to the interior, they also have functional features like emphasising and masking and ecological characteristics such as absorbing harmful substances in the environment. However, indoor plants can cause some toxic effects on the users (people and domestic animals). In the scope of this study, which is carried out in the central districts of the province of Bursa, the species evaluated as indoor plant are examined in terms of their toxic properties. The data obtained shows that only 25,92% of indoor plants that are sold the most are not toxic. It has been determined that Anthurium scherzerianum, Dieffenbachia maculata, Dieffenbachia seguine, Dracaena deremensis, Dracaena fragrans massengena, Dracaena marginata, Spathiphyllum wallisii and Yucca aloifolia are preliminary toxic plants for domestic animals.

The coastal areas, which have always attracted the attention of humankind in the past, have very rich resource values in terms of recreational use and efficiency diversity. The coastal areas have been planned and designed in accordance with the relevant purposes by serving for various purposes such as settlement, transportation, recreation and tourism throughout history. In this context, many studies about coastal areas aimed active and free utilization of people from the coastal areas and the sustainable use and planning of them. The aim of this study is to determine the recreational use potential of the coastal areas by studying the legal and technical aspects of the usage of the first 50 m wide part of coastal and shoreline of Hopa and Arhavi districts of Artvin province on the coast of Black Sea. The study was carried out in a coastal zone with a total of 36.2 km in the province of Artvin. It was handled under seven chapters considering the administrative borders and the planned / unplanned area. The plans prepared for the filling areas with the 1/1000 scaled approved Implementation Plans are the materials used for the study of the potential areas and the pictures from Drone for the recreation obtained by evaluating the entire field during the field studies. ArcMap 10.4, Google Earth and Photoshop CS6 programs were used to organize the generated maps. As a result of all these reviews and evaluations, it has been determined that the unfavorable conditions of the coastal land limit the coastal area and recreational use, and the shoreline has been subjected to unsuitable land use. It has been found that there are recreational purposes in the coastal land and shoreline covered by the planned area, and that the planned areas are exposed to the wrong coastal use more than the unplanned areas. It has also been determined that the coastal width of the study area varies between 0,5 m and 215 m and is mostly of a narrow coastal nature.

In this study, paper pulp and test papers were produced with the European blackpine (Pinus nigra Arn.) Kraft method. In order to investigate the effect of chip width on the yield of pulp, the cooking temperature, duration and chemical amount were kept constant and chip size and thickness were fixed in a certain average, and 3 different chip widths were made in 3 chip widths obtained from sieve chips in different size sieves. The chip width is reduced and the yield of pulp and reject are decreased. The highest sieved yield (53.60%) was obtained from the 17.5 mm sieve and from the remaining chips from the 8.5 mm sieve. As the chip width increased, the reject increased. The reject increase is the highest calculated on the widest chips.

Depending on the storage periods, changing in the technological properties ocur, changing in the storage time of particleboard produced factory environment effects significantly usage place of particle board. Therefore, immediately after the press exist of produced particles in this study it is aimed to be measured test results of some physical (moisture content, density, water uptake and thickness swelling) and mechanical properties in condition periods. The effects of technological properties of the storage time of the particle board was investigated by comparing the values obtained at the end of 1st day, 7th day, 14th, 21th day and 28th day after 15 minutes press output. In the obtained results, some technological properties of particle board has been observed to be effective. Bending strength and internal bond strength increase was observed depending on the storage period. According to this, it can be stated that it is more appropriate to wait for at least 15 days under suitable storage conditions before sale.

The increase in the use of wood panel products with the increasing population and industrialization brings with it the development and capacity increase in the wood panel industry. Turkey, which is of an important place in the industrial wood panels all around the world, should give more importance to the industry-relevant analyses and projections in order to maintain its current position in the industry and promote it to an upper level under competitive conditions. In this study, it was aimed to determine the optimal estimation method that can predict the production amounts of wood panels. In this regard, based on the production values between 1981 and 2003, the values up to 2015 were estimated through regression and ARMA methods and they were compared with the actual values. The obtained results and comparisons showed that the optimal estimation values are obtained via the ARMA method in Turkey

Global warming is regarded as one of the most important problems of our century. In almost all scientific circles and media organizations, there is a common opinion that the world is getting warmer. It is estimated that the world temperature will increase between 1.5 °C and 5.0 °C during the 21st century. In Turkey around 2030, it is reported that the summer and winter temperatures will increase around 2.0 °C-3.0 °C, winter precipitation will increase by up to 10%, summer precipitation will decrease and, the drought in terms of soil moisture will increase. In this study, the minimum, maximum and average temperature values and maximum and total precipitation amounts between 1980-1999 and 2000-2015 for the central meteorological stations of Bartin, Zonguldak and Düzce Provinces in Western Black Sea Region of our country were examined. The results indicate the marked increases in minimum and maximum temperatures monthly basis. At the same time, increasing tendency was determined in the Bartin, Zonguldak and Düzce monthly and annual average temperature data, especially during the summer months. On the other hand, in the period between 1980-1999 and 2000-2015 years monthly and annual, especially during the summer months (June, July and August), average precipitation data showed a tendency to decrease. Turkey is among the riskiest countries from the point of the possibility to experience the potential consequences of global warming. Unless measures are taken against climate change, it will be inevitable that the climate change would degrade the composition and productivity of the natural ecological systems in our country and reduce biological diversity.

The plants of the Lemnoideae subfamily are the smallest group of flowering plants. In this study, the distribution areas of Lemnoidea species in areas where important wetlands of Turkey and some ecological characteristics were investigated. Coordinates of locations of duckweeds genotypes are mapped with ArcGIS program. 67 genotype plant samples representing 5 different species of duckweed members were identified. Three genotypes belonging to L. turionifera in the field studies; 4 genotypes belonging to S. polyrhiza; 7 genotypes belonging to Lemna trisulca. It was determined that 9 genotypes belong to L.gibba and 44 genotypes belong to L. minor. The altitudes of the areas identified as duckweed were in a wide range (1-1734 m). Duckweeds are important advantages: (1) they can be evaluated as a model plant, potentialities of use in bioremediation studies, (2) they can be used as food for fish and other animals due to the high protein content they contain and (3) they can be evaluated as biofuels because they have high starch content. The duckweed member plants whose distribution areas are determined in Turkey can be evaluated for these purposes.
