II. Meşrutiyet Dönemi’nin Toplumsal bir Yardım Kuruluşu: Osmanlı Donanma Cemiyeti
Authors: AYSAL Necdet
Published: June 2020

Toplumsal yardım ve güvenlik, sosyal yaşamın önemli unsurlarından birisidir. Dünyada uzun yıllar devam eden savaşlar, büyük nüfus kayıplarının yaşanma-sına neden olmuştur. Bu bağlamda toplumu oluşturan bireylerin yaşamsal ihti-yaçları iaşe, sağlık, eğitim ve güvenlik gibi önemli toplumsal beklentiler yete-rince karşılanamamıştır. Sosyal yardım konusunda bir kurumsallaşmanın ol-madığı dönemlerde halkın ihtiyaçları daha çok geleneksel yollarla karşılanmaya çalışılmıştır. Ancak 19. Yüzyılın ortalarından itibaren sanayi devriminin berabe-rinde getirdiği sosyal şartlar, geleneksel yardım anlayışının sosyal devlet sis-temi içerisinde dernek ve cemiyetler vasıtasıyla ele alınmasına yol açmıştır. Modernleşmenin hız kazandığı Tanzimat döneminde kurulmaya başlanan cemi-yet ve dernekler, Meşrutiyet döneminde daha da artış göstermiş, toplumsal ya-şamın ayrılmaz bir parçasını oluşturmuştur. Hiçbir yasal sınırlama tanımaksı-zın, kendiliğinden kurulan bu cemiyetler ancak 1909’da Cemiyetler Kanunu ile meşruiyet kazanmıştır. Aynı yıl içerisinde cemiyet kurma hakkı, Kanun-ı Esa-si’de yapılan bir değişiklikle anayasal güvence altına alınmıştır. Bu dönemde hayır ve yardım amaçlı kurulan cemiyetlerden birisi de Osmanlı Donanma Ce-miyeti’dir. 19 Temmuz 1909’da İstanbul’da gönüllü Müslüman ve Gayrimüslim halkın girişimleriyle kurulan Cemiyet, yapmış olduğu faaliyetlerle kısa süre içerisinde adını duyurmuş ve yasal bir statüye kavuşmuştur. Bu çalışmada Do-nanma Cemiyeti’nin gelir kaynakları ve yardım toplama usulleri, başta A.Ü. Tİ-TE Arşiv belgeleri olmak üzere araştırma eserleri ve basın çerçevesinde incele-nerek değerlendirilmiştir.
Impacts of Socio-Economic Factors on Carbon Dynamics in Black Sea Forests: A Case Study from Akçaabat
Authors: MUMCU KÜÇÜKER Derya
Published: June 2020

Forest ecosystems play a crucial role in mitigating the negative impacts of global climate change as an essential carbon sink. Land use and land cover change, mainly deforestation, degradation, and afforestation, have significantly affected carbon (C) stock. This study analyzed the effects of land use and land cover changes on forest C dynamics and its spatial distribution based on demographic, socio-economic, and landscape structure in the Akçaabat forest planning unit. Moreover, forest C dynamics in aboveground, belowground, deadwood, litter, and soil were calculated separately based on forest inventory data in 1984, 2008, and 2018. While the total C stock increased by about 38.04% between 1984 and 2008, it increased only by about 4.64% between 1984 to 2018 due mainly to not including of non-state-owned areas covered with forest trees (about 4369.40 ha) in the forest management plans developed based on land cadastre in 2018. The most considerable contribution to the C pool was from the soil by about 73.39%, 72.32% and 61.60% in 1984, 2008 and 2018, respectively. Deciduous cover types, young and full covered forests, had the highest average C density with 442.61 Mg ha-1 49.65 Mg ha-1 and 144.47 Mg ha-1, respectively. Over three decades, the conversion from degraded, forest opening, and non-forest areas to productive forests as well as increasing the quality of forest structure characterized by increasing mixed forest, young or mature development stages, and full covered forests has contributed positively to the C stock. This increase in the quality of the forest can be explained by conversion abandoned agriculture areas to forested areas with migration, reduction of social pressure on forested areas based on decreasing forest crime, and increasing forest crime, and increasing aware awareness and increasing awareness and sensitivity to the environment based on economic development. Analyzing the spatiotemporal patterns and driving factors of carbon dynamics are critical in developing appropriate planning strategies to control climate change.

La acariasis es un problema común en el erizo pigmeo africano (Atelerix albiventris). Caparinia trípilis es responsable por la infestación por ácaros más frecuente. La presencia de sarna es común y puede causar co-infecciones bacterianas. El trabajo describe dos casos de sarna por Caparinia trípilis en el erizo pigmeo africano, un macho y una hembra, adultos, diagnosticados mediante evaluación clínica y microscópica de lesiones obtenidas por raspado. Los pacientes acudieron a consulta debido a que presentaban prurito intenso y caída excesiva de púas. El tratamiento consistió en la aplicación de ivermectina a dosis de 0,4 mg/kg por vía subcutánea. Se realizó realizado el control clínico de los pacientes a los 14 días, con la re-aplicación de la ivermectina, a la misma dosis. Al control se pudo observar una mejoría clínica completa. La presencia de Caparinia trípilis en erizos ha sido descrita ampliamente en los Estados Unidos de Norte América, Nueva Zelanda, y varios países de Europa, pero aún se requiere información de Centro y Sudamérica, y se informa aquí su presencia en Paraguay.
An explicit topology optimization method using moving polygonal morphable voids (MPMVs)
Authors: Van-Nam Hoang
Published: June 2020

Introduction: Conventional topology optimization approaches are implemented in an implicit manner with a very large number of design variables, requiring large storage and computation costs. In this study, an explicit topology optimization approach is proposed by movonal morphable voids whose geometry parameters are considered as design variables.

Methods: Each polygonal void plays as an empty-material zone that can move, change its shapes, and overlap with its neighbors in a design space. The geometry eters of MPMVs consisting of the coordinates of polygonal vertices are utilized to render the structure in the design domain in an element density field. The density function of the elements located inside polygonal voids is described by a smooth exponential function that allows utilizing gradient-based optimization solvers.

Results & Conclusion: Compared with conventional topology optimization approaches, the MPMV approach uses fewer design variables, ensure mesh-independence solution without filtering techniques or perimeter constraints. Several numerical examples are solved to validate the efficiency of the MPMV approach.

Conservation Status of Greater One-horned Rhinoceros (Rhinoceros unicornis) in Nepal: A Review of Current Efforts and Challenges
Authors: Ghimire Pramod
Published: June 2020

The greater one-horned rhinoceros (Rhinoceros unicornis) is one of the iconic natural heritage of Nepal’s rich biological diversity, backed by the commitment of the Government of Nepal to conserve this rare animal for now and future generations. It is not only important for conservationists due to its ecological value, but it also holds a universal appeal for ordinary people. Over the decades, the Government of Nepal, supported by national and international conservation partner organizations and the local communities, has significantly contributed to the conservation of this iconic species. Nepal’s rhino population has increased by 45% between the year 2005 and 2015. There are now 645 rhinos in Nepal, marking an increase of 111 rhinos from the 534 recorded in the last census in 2011. These numbers reflect the success of conservation efforts for this species and are a result of improved rhino protection measures, and management of habitat. Though the population of one-horned rhinos has increased significantly over past years in the country, the protection of the rare wildlife species has remained a challenging job. Habitat loss and fragmentation, increasing encroachment of forest areas, climate change, poaching, and increasing human-wildlife conflict are major challenges for protection of this rare species. This paper discusses the current status and distribution of greater one-horned rhinoceros, and potential challenges to conserve this flagship species in Nepal.

Authors: Bhattarai Rajeev , Sharma Puja , Wagle Bishnu , Adhikari Angel , Acharya Suman
Published: June 2020

Acacia catechu (Khair) is one of the significant tree species evolved together with Nepali communities. The tree is widely used for medicinal purposes, feeding the livestock, fulfilling the structural needs, and satisfying religious and spiritual needs. Despite the wide use and importance of this tree, the available publications have failed to address the risks the tree is vulnerable to, and develop a management design to overcome these threats. Due to these reasons, the people are growing the Khair trees without any robust health management plan. The abundance and overall importance of this tree in the South Asian region strongly demands an interpretative and comprehensive way of its cultivation. This study is aimed towards bringing together the available information on Khair and finally coming up with an advantageous management plan that can deal with all the hazards the tree is prone to, and help in the production of healthy and of economically high-value timber. This study only deals with two of the several prevalent fungal stresses-Ganoderma lucidum and Fomes badius, causing root rot and heart rot, respectively, putting the tree under risk. The heart rot and root rot are capable of destroying the whole site rendering the trees useless for consumption. The findings from this study can help cultivators know the nature of the diseases and their occurrences and improve the way of cultivating the tree and take prompt actions on the syndromes.
Paradox of Rice Seed System in India
Authors: Hossain S.K. Mosharaf , Nayak Swati
Published: June 2020

Importance of rice in agrarian economy of India is enormous. In order to meet demand of this staple crop for increasing population, productivity enhancement is a key research and development agenda. Improving seed replacement rate is widely held as a critical area to boost rice productivity in the country. This study based on secondary data revealed merely sowing quality seeds may not result in desired level of yield increase unless quality seeds of a good and appropriate variety is sown. Punjab, with its 38% SRR, registers 3.97 ton per ha yield whereas it is just 1.51 ton per ha in Chattisgarh where SRR is 44%. There are many varieties, quite older than stipulated 10 years, that are largely indented and grown due to lack of substitutes and poor varietal awareness. Because of this slow varietal awareness and replacement, rice yield still stagnates despite seeds are of assured quality. This shows varietal replacement rate is as important as seed replacement rate. The available studies also indicate that current seed system further needs to rationalize variety selection, production and multiplication of breeder seeds for ensuring seed security of farmers and this should be supplemented by measures taken to promote varietal promotion and replacement, quality seed production interventions at farmers’ level, and decentralized seed production system.

Published: June 2020

Nutrient concentration is an important parameter to recognize critical processes of an ecosystem and environmental quality. This paper is based on a study carried out to evaluate the nutrient status in sediments, water and plant leaves from Ratargul swamp forest of Bangladesh during the period from September 2016 to August 2017. The samples were collected from twelve sampling stations of four different canals during dry (September 2016 to April 2017) and wet (May to August, 2017) seasons, respectively. The nutrient contents such as total nitrogen (TN), available phosphorus (AP) and total organic carbon (TOC) were analysed in the laboratory of the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, Bangladesh. The TN, AP and TOC in sediments were ranged from 2.22 to 5.23, 0.032 to 0.035 and 2.6 to 4.52%, respectively, whereas TN and AP in water were found 5.34 to 22.54% and 0.002 to 0.366%, respectively. Result showed that the TOC in plant leaves was higher in wet season than in dry season, where the TN and AP were higher in dry season than in wet season due to high temperature which increases the rate of photosynthetic activities in the dry season. In both Korochand Hijal plants, the TOC and AP were higher in green leaves than brown leaves, while TN was higher in brown leaves than green ones. Moreover, a statistically significant positive correlation was found among the samples. The study concluded that the nutrient status in sediments, water and leaves were perfectly natural during both the dry and wet season.

Authors: Dinata Irwan
Published: June 2020

Pada komunikasi wireless, tuntutan untuk menyediakan layanan data kecepatan tinggi dengan memberikan kinerja yang baik memunculkan teknik baru dalam peningkatan efisiensi spektrum dan perbaikan kualitas sinyal akibat frequency selective fading. OFDM merupakan teknik multi-carrier yang paling banyak digunakan untuk memenuhi semua tuntutan tersebut. Tetapi dalam pengembangannya, OFDM ini masih memiliki beberapa kelemahan diantaranya masih besarnya nilai PAPR dan kurangnya perbaikan efisiensi spektral daya, sehingga digunakan OWDM untuk mengatasi kekurangan tersebut. Pada OWDM, Invers wavelet packet transform (IWPT) digunakan untuk membangkitkan simbol terkirim pada transmitter dan forward wavelet packet transform (WPT) akan mengembalikan simbol data terkirim tersebut pada receiver. Sistem OWDM ini akan membagi band frekuensi ke dalam beberapa sub-band yang berdiri independen dan terisolasi secara spektral yang disebut subchannelization. Dari hasil simulasi didapatkan OWDM memberikan beberapa hal yang dapat dibandingkan dengan OFDM. OWDM memberikan kinerja yang unggul dalam mereduksi nilai PAPR yang dihasilkan. Untuk OWDM sendiri jika diimplentasikan maka nilai PAPR terkecil dihasilkan pada orde wavelet yang kecil, wavelet Coiflet, penggunaan jumlah sub-band  yang sedikit dan modulasi QPSK.

KLASIFIKASI BIT-PLANE NOISE PADA GAMBAR MENGGUNAKAN LOGIKA FUZZY
Authors: Hidayat Rahmad
Published: June 2020

Teknik steganografi BPCS (Bit-Plane Complexity Segmentation) merupakan salah satu teknik steganografi yang cukup baru. Salah satu proses penting dalam Teknik Steganografi BPCS adalah proses penghitungan nilai kompleksitas suatu bit-plane. Nilai kompleksitas dihitung dengan melihat seberapa banyak pergantian bit yang terdapat dalam sebuah bit-plane. Jika bit-plane tersebut memiliki nilai kompleksitas yang tinggi, maka bi-plane tersebut dikategorikan sebagai bit-plane noise yang tidak mengandung informasi yang berharga pada gambar. Klasifikasi bit-plane yang menggunakan himpunan cripst (noise dan tidak) tersebut tidak adil, dimana sebuah perbedaaan nilai yang sedikit saja akan mengubah secara signifikan status dari bit-plane tersebut. Penelitian ini mencoba untuk menerapkan prinsip himpunan  fuzzy untuk  mengklasifikasikan bit-plane menjadi kedalam tiga buah himpunan yaitu informatif, informatif sebagian, dan noise region. Klasifikasi bit-plane kedalam himpunan fuzzy terebut diharapkan dapat menggolongkan bit-plane secara lebih objektif dan pada akhirnya daya tampung gambar terhadap pesan dapat ditingkatkan dengan dengan menggunakan inferensi fuzzy mamdani untuk mengambil keputusan bit-plane mana yang akan digantikan dengan pesan berdasarkan klasfikasi bit-plane yang tersedia dan ukuran pesan yang akan disisipkan.

Hydropower is considered to be one of important renewable energy sources. Renewable energy is the second-largest contributor to global electricity production after fossil fuel. Hydropower generation presents several advantages over most other sources of electrical power. It includes a high level of reliability, proven technology, high efficiency (about 90%), very low operating and maintenance costs, flexibility and large storage capacity. Based on the types of installation, hydropower can be categorized as; impoundment, diversion, and pump storage, and based on the turbine types can it be classified as reaction and impulse systems. Previous research gives the results of the initial survey, concluding that there are two rivers that have the potential to become a micro or mini-hydro generator. Way Laai and Way Lami.  So, we need to know what is turbines type to suit  both of river Way Laai and Way Lami. We used the same method with other research that used TURBNPRO software for helping in the design of Turbines. The simulation result gives one alternative to the right turbine design for Way Laai is the orientation vertical of 6 jet Pelton with a peak efficiency of 89.9%. The right alternative turbine design for Way Lami is the vertical orientation Axial turbine/ propeller design with a peak efficiency of 93.3%.

Bidang pemetaan lahan skala kecil menggunakan UAV (Unmanned Aerial Vehicle) sebagai sarana  pemetaan. UAV memerlukan komunikasi tanpa kabel (wireless) dengan jarak yang jauh dan stabil. Untuk itu dibutuhkan sebuah antena dengan pola pancaran yang jauh dan penguatan (gain) yang tinggi. Penelitian ini menggunakan Antena Yagi karena memiliki pola pancaran yang terarah (directional)  tetapi memilki kelemahan yaitu, antena yagi harus diarahkan secara pointing untuk menjaga komunikasi antara antena dan UAV. Berdasarkan hasil perhitungan dan simulasi antena yagi dengan frekuensi 433 MHz, diperoleh penguatan (gain) sebesar 14,2 dBi. Rancangan antenna yagi dibuat menggunakan Almunium dan tembaga berbentuk pipa. Dari hasil pengujian jarak komunikasi didapat jarak jangkauan ± 5 km. Pengujian dilakukan dengan memasangkan antena yagi ke modul receiver telemetri 433 MHz, kemudian modul transceiver dipasang di pesawat tanpa awak (UAV) yang diterbangkan.
