„Ég held ég hafi bara ekki vitað hvað hamingja var áður en þau fæddust“: Upplifun feðra af hamingju
Authors: Gunnarsdóttir Pála Margrét , Kaldalóns Ingibjörg V. , Ingudóttir Hrund Þórarnis
Published: February 2022

Lítið er um rannsóknir á áhrifum barneigna og barnauppeldis á hamingju feðra. Markmið þessarar rannsóknar var að öðlast aukinn skilning á hvernig feður upplifa hamingju við að eignast og eiga börn. Fyrirbærafræðilegri nálgun var beitt, þar sem tekin voru opin viðtöl við níu feður. Þeir áttu tvö til þrjú börn, 13 ára eða yngri, og bjuggu allir með barnsmóður sinni. Upplifun feðranna á hamingju var skoðuð út frá þremur kenningum um hamingju; kenningu um jákvæðar tilfinningar, sjálfsákvörðunarkenningu um farsæld og sálrænar grunnþarfir, og kenningu um hamingju út frá auknum lífstilgangi. Niðurstöður rannsóknarinnar sýndu að feðurnir upplifðu hamingjuna á annan hátt eftir að þeir eignuðust börn. Þeir upplifðu meira af jákvæðum tilfinningum; djúpstæðri ást, gleði og þakklæti eftir að þeir eignuðust börnin en áður. Feðurnir tengdu hamingjuna því að hve miklu leyti þeir gætu ráðið sér sjálfir, hversu hæfir þeir töldu sig vera til að sinna foreldrahlutverkinu og hvernig þeir tengdust börnunum. Einnig lýstu þeir auknum lífstilgangi eftir að þeir eignuðust börnin og að hamingjan yrði merkingarbærri og innihaldsríkari. Þrátt fyrir að lífið með börnunum veitti þeim hamingju töldu þeir það líka krefjandi og að mörgu leyti erfiðara en áður, þar sem þeir leituðust við að sinna uppeldi, samræma vinnu og fjölskyldulíf og hafa tíma fyrir maka, vini og áhugamál. Í heildina virtist það þó engu máli skipta í samanburði við þá hamingju sem börnin veittu þeim. Ekki er vitað til þess að hamingja feðra hafi verið rannsökuð með þessum hætti áður. Rannsóknin er mikilvægt framlag til rannsókna á hamingju innan jákvæðrar sálfræði sem og rannsókna á upplifun feðra af hlutverki sínu.

Calculating the financial result on the Goods Inventory account: The historical and methodological aspect. Part 1
Authors: KOLCHUGIN Sergei V.
Published: February 2022

Subject. This article examines the problem of identifying the financial result on the Goods Inventory account. For the first time, the procedure for determining the financial result on the Goods Inventory account was described by Luca Pacioli in the twenty-seventh chapter of his Treatise on the Accounts and Records (Particularis de Computis et Scripturis) in 1494. It raises many questions.
Objectives. The article aims to reconstruct the procedure for identifying the financial result on the account Goods Inventory on the basis of medieval treatises on accounting. It also aims to prove that medieval treatises on accounting published after the publication of Luca Pacioli's Treatise on the Accounts and Records are of independent scientific value.
Methods. For the study, I used combinations of analysis and synthesis, induction and deduction, and historical and logical research methods.
Results. Based on the study of the works of medieval authors, the article reconstructs the procedure for determining the financial result on the account Goods Inventory and proves that medieval works on accounting, published before the end of the 16th century, had independent scientific significance.
Relevance. The results obtained can be applied to explain the nature of the financial result, and when defining the financial result and developing an accounting methodology for identifying it.

Mengapa Negosiasi Internasional Gagal? Menjelaskan Kegagalan Perundingan Denuklirisasi Amerika Serikat- Korea Utara 2019
Authors: Rosyidin Mohamad , Sabrina Ayu , Hanjani Annisa Antania , Kusumawardhana Indra
Published: February 2022

This article aims to explain the failure of US-North Korea’s denuclearization negotiation in 2019. There has not been research on this topic. In general, existing literature proposes four factors that explain the failure of international negotiation, namely, actor, structure, strategy, and process. This article contributes to existing literature by adding another variable in explaining diplomatic failure. Using Charles Kupchan’s concept of unilateral accommodation, this article argues that the failure of US-North Korea’s denuclearization negotiation in 2019 is caused by the failure at the unilateral accommodation stage due to US distrust over North Korean’s commitment in dismantling its nuclear program. Despite the fact that North Korea has sent a positive signal to the US – for example by destroying its nuclear facilities and returning US prisoners of war and soldiers’ body – the US remains unfazed. This article demonstrates that the negotiation process is largely determined by the first stage in which each party gives concessions in order to create mutual trust.
The Dilemma of Handling Asylum Seekers and Illegal Migrants: Expectation and Reality
Authors: Hanura Marten , Windiani Reni , Utomo Tri Cahyo
Published: February 2022

The number of refugees and illegal migrants fleeing to Indonesia keeps growing significantly since Indonesia poses as a strategic place for a temporary stop before their main destination. This surely brings about predicaments to Indonesia. Against that background, this research aims toanswer the question of "How does the Indonesian government respond to the illegal migrant and refugees problem through the Immigration Detention Center (Rudenim) Semarang in Central Java?". This research is an explanatory research, where both primary and secondary data are used to support the findings. Through a qualitative approach, this research foundthat the government has responded to illegal migrant and refugees problems in a quite excellent manner such as the establishment of rumah detensi imigrasi (rudenim) or detention house and other forms of international cooperation. However, asylum seekers in Indonesia are not fully protected due to some factors such as the lack of regulation, the long-waiting period for the permanent placement and the lack of basic needs.Lastly, the situation only got worse because of the IOM and UNHCR support is still not optimal.

Authors: Vivi G , Noviadi R , Rumiyani T
Published: February 2022

Efforts to apply embryo transfer reproductive technology to community breeders in Lampung Tengah Regency involve inseminators who have an interest and influence in the success of embryo transfer. This study aims to analyze the inseminator response to the implementation of embryo transfer in Lampung Tengah Regency by looking at the influence of age (X1), education level (X2), work experience (X3), knowledge (X4), means of transportation (X5), and facilities and infrastructure (X6) owned by the inseminator of the inseminator's response to the application of embryo transfer in Lampung Tengah Regency. The analytical method used is simple linear regression analysis of 28 inseminators on duty in Lampung Tengah Regency. The results showed that the more productive the inseminator age (old), the lower the inseminator response. Meanwhile, the level of education, work experience, knowledge, means of transportation, and facilities and infrastructure owned by the inseminator in Lampung Tengah did not have a significant positive effect on the inseminator's response regarding the implementation of embryo transfer in Lampung Tengah Regency, Lampung Province.
The Odyssey of publications during residency–the much needed yet challenging journey
Authors: R Vignesh Narayan , Dogra Sunil
Published: February 2022

There is no greater joy than contributing back to the field that one chooses to specialize in. This noble feat of scientific publication can, however, be a daunting task for those who are in the nascent period of their residency. They need to strike that fine balance between academic learning, patient care, and publication without burning themselves out. This exercise is best capitalized in that window period of the 2nd year of residency. They will thus be updated, forming long-term memory. The topic chosen should belong to the area of their interest, but at the same time be current and timely. They need to master electronic data base search, learning the correct use of operators and filters. An extra edge can be gained with the help of reference managers, which can summarize, retrieve, and organize all relevant literature. Writer’s block can be overcome by writing the easiest part of the paper first and using a pre-existing publication as a template. The lingo and flow ideas must be academic, scientific, and captivating, yet be simple and comprehensible. A right platform to showcase the research must be found, evading predatory journals. Effort and creativity must go hand in hand to make the article captivating. Residents must be prepared for revisions and gracefully respond. The process is simple and a lot will be learnt along the way.
The contribution of the non-profit sector in narrowing spatial inequalities
Authors: Salustri Andrea , Viganò Federica
Published: February 2022

In this chapter we illustrate how the public sector might fail in narrowing spatial inequalities, and how both underdeveloped markets and urgent territorial needs create in peripheral areas robust individual incentives to turn into non-profit activities or even household production. In all those situations, a well-developed non-profit sector can offer marginalized or excluded social groups a legal and ethical opportunity to obtain a decent income by offering rewards (monetary or nonmonetary) in exchange for volunteering, allowing households to afford the cost of living. Laying on the results of the analysis, we discuss four cases of successful cooperation among SSE institutions by one side, and the private and the public sector on the other. In all those cases, the private and the public sector decided to facilitate the development of the non-profit sector by contracting out part of the production process to reduce costs and achieve a higher level of effectiveness. The result was successful because the non-profit sector did not incur in the opportunistic behaviors that might affect profit-oriented activities. Therefore, we suggest how local inter-institutional cooperation among the SSE, the private and the public sector should become the norm rather than the exception, in order to achieve at the same time a higher level of equitable and sustainable development and well-being.
Multi-stakeholder governance of the commons, a pragmatic approach
Authors: Lapoutte Alexandrine
Published: February 2022

The question of the governance is central for the commons. They have to compose with the different logics of multiple stakeholders within a horizontal governance. The good governance of the commons relies on problem solving devices and discussion settlements. They may be seen as hybrid organizations, a promising way of organizing, yet experiencing intense internal conflicts. This chapter proposes a theoretical contribution that underlines the relevancy of a pragmatist approach to understand the governance of the commons. Stakeholder governance is defined by the literature, yet its theoretical settlements remain plural. Beyond a contractual approach, a pragmatic point of view renews the foundation of stakeholder approach by suggesting to take into account experience and social interaction. After explaining the main features of pragmatism, and especially the concept of inquiry, we highlight the implications of this approach as regards to stakeholder management. The pragmatic shift appears as an interesting approach to keep pace with the shift in paradigm observed in the cooperation between public economy and social economy for the development of commons and public goods.
Redefining the borders between public, social economy and for-profit organizations in the provision of public services
Authors: Saito Shinichi , Nomura Munenori , Mizutani Fumitoshi , Rawlinson Francis
Published: February 2022

Japan’s public services including public utilities have traditionally been provided by the public sector with strong government involvement through regulation or ownership. In this chapter, we look at the current situation and the issues surrounding institutional reform in the field of public services. Although private participation is a possible option in some cases, the underlying market conditions are a determining factor. Some rural areas are facing major difficulties in maintaining public services and public infrastructure. Are there alternative ways of maintaining services and infrastructure in such areas? We describe options such as restructuring and the foundation of “social businesses”. The options discussed extend the former concept of PPP from the relationship between private operators and the public sector to one involving beneficiaries including local residents as well. Such social enterprises, which are independent both from the private commercial companies involved in service provision and of the public sector, are one means of regenerating local communities. The contribution thus indicates the shifting roles of the public sector from direct service provider towards a supporting intermediary.
Understanding financialization and its impacts on Social Economy
Authors: Belo Moreira Manuel
Published: February 2022

Following a political economy perspective about financialization and its impacts on social economy, it seems important to understand the role of the neoliberal ideological hegemony and the ways in which, it not only influences academic thinking, but it goes well beyond, by shaping the “common sense” and therefore reinforcing its dominance. Describing the essential features of the financialization process brings to light the driving forces and the mechanisms that were put into practice and, finally, explains why, in spite of its negative effects which could provoke a rejection by the majority, the ideology is nonetheless reinforced. The text seeks to establish a framework concerning the impacts of financialization on the social economy sector, by reflecting what the main differences are between the different branches of social economy and how they can be affected by neoliberal ideology and policies. It seems particularly important to separate the institutions of social economy that do not compete with profit firms from the institutions that by competing on the market could function as an alternative to capitalist enterprises
Finance as a ‘commons’ understood as ideal-type for emancipation
Authors: Paranque Bernard
Published: February 2022

We use an ideal-type approach to analyse ‘interstices’ in which emancipation could appear. The question is how use value can escape from the domination of exchange value, and how could we promote another kind of private property freed from capital. In particular we critique the assimilation of the firm to the company. We refer to the research based on the ‘commons’ to open new proposals, in particular one concerning finance as a commons.
The development in France of partnerships between public and social economy organizations and the new paradigm of public action
Authors: Bance Philippe , Milesy Jean-Philippe , Zagbayou Christelle
Published: February 2022

The chapter explains why and how the institutional and social transformations that have taken place in France during the last decades with the advent of the new public management are at the origin of new forms of cooperation between social economy organisations provided in the past by public organisations or private companies providing public services and in charge of the missions entrusted to them. Today, public and social economy partnerships are encouraged by public enterprises, public non-market organisations or public authorities, which see it as a means to extend public service delivery in a context of reducing financial resources. These transformations have the advantage of the cooperation of different organisations to maintain or increase public service provisions for the benefit of citizens. However, the future of this emerging model raises three main interrogations: the capacity of social economy organisations to retain their own identity by becoming largely providers of public organisations or authorities; the resilience of the fundamentally centralist conception which permeates the French model and limits the scope of these new partnerships; and last the banalization of social economy organisations as a result of the deployment of new public management and the neoliberal conception that limit the ability to co-construct the general interest with the different partners.
Key Performance Indicators of Public-Owned Enterprises (POEs) in North Macedonia
Authors: Zulfiu Alili Merita
Published: February 2022

Private sector leads the production and distribution process in many countries. However, Public Owned Enterprises (POEs) are also an important element of many developing and developed economies in this context. This analysis examines the main legal organisation forms of public owned enterprises and their financial performance. It also briefly analyses the national legislation and regulation on corruption prevention mechanisms and policy measures and anticorruption practices in public owned enterprises. Almost half of public owned enterprises in North Macedonia are working with losses and have the highest maturity and unpaid liabilities in the last five years. Public owned enterprises can either contribute or obstruct the competitiveness of the economy depending on their efficiency and productivity. This sector needs to be transparent to provide competing enterprises with a fair overview of the fundamental market conditions.
High Temperature Oxidation of Single Carbon Nanoparticles: Dependence on Surface Structure, and Probing Real-Time Structural Evolution via Kinetics.
Authors: Rodriguez Daniel , Lau Chris , Friese Abigail , Magasinski Alexandre , Yushin Gleb , Anderson Scott
Published: February 2022

O2-oxidation and sublimation kinetics for >30 individual nanoparticles (NPs) of five different feedstocks (graphite, graphene oxide, carbon black, diamond, and nano-onion) were measured using single nanoparticle mass spectrometry at temperatures (TNP) in 1100 – 2900 K range. It was found that oxidation, studied in the 1200 to 1600 K range, is highly sensitive to NP sur-face structure, with etching efficiencies (EEO2) varying by up to four orders of magnitude, whereas sublimation rates, significant only for TNP ≥ ~1700 K, varied by only a factor of ~3. Its sensitivity to NP surface structure makes O2 etching a good real-time structure probe, which was used to follow evolution of the NP surface structures over time as they were either etched or an-nealed at high TNP. All types of carbon NPs were found to have initial EEO2 values in the range near 10-3 Da/O2 collision, and all eventually evolved to become essentially inert to O2 (EEO2 < 10-6 Da/O2 collision), however, the dependence of EEO2 on time and mass loss was very different for NPs from different feedstocks. For example, diamond NPs evolved rapidly and monoton-ically toward inertness, and evolution occurred in both oxidizing and inert atmospheres. In contrast, graphite NPs evolved only under oxidizing conditions, and etched with complex time dependence, with multiple waves of fast-but-non-monotonic etching, separated by periods of near-inertness. Possible mechanisms to account for the complex etching behavior are pro-posed.

Published: February 2022

Novel trisubstituted ethylenes, dimethyl, dimethoxy, and halogen ring-substituted isopropyl cyanophenylacrylates, RPhCH=C(CN)CO2CH(CH3)2 (where R is 2,3-dimethyl, 2,4-dimethyl, 2,5-dimethyl, 2,6-dimethyl, 3,4-dimethyl, 3,5-dimethyl, 2,3-dimethoxy, 2,4-dimethoxy, 2,5-dimethoxy, 2-Br, 3-Br, 4-Br, 2-Cl, 3-Cl, 4-Cl, 2-F, 3-F, 4-F) were prepared and copolymerized with styrene. The monomers were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and isopropyl cyanoacetate and characterized by CHN elemental analysis, IR, 1H- and 13C-NMR. All the ethylenes were copolymerized with styrene in solution with radical initiation (ABCN) at 70C. The composition of the copolymers was calculated from nitrogen analysis, and the structures were analyzed by IR, 1H and 13C-NMR, GPC, DSC, and TGA. Decomposition of the copolymers in nitrogen occurred in two steps, first in the 219-500C range with residue (0.9-5.6 % wt), which then decomposed in the 500-800ºC range.

Published: February 2022

Neointimal hyperplasia/proliferation (IH) is the primary etiology of vascular stenosis. Epigenomic studies concerning IH have been largely confined to in vitro models, and IH-underlying epigenetic mechanisms remain poorly understood. This study integrates information from in vivo epigenomic mapping, conditional knockout, gene transfer and pharmacology in rodent models of IH. The data from injured (IH-prone) rat arteries revealed a surge of genome-wide occupancy by histone-3 lysine-27 trimethylation (H3K27me3), a gene-repression mark. This was unexpected in the traditional view of prevailing post-injury gene activation rather than repression. Further analysis illustrated a shift of H3K27me3 enrichment to anti-proliferative genes, from pro-proliferative genes where gene-activation mark H3K27ac(acetylation) accumulated instead. H3K27ac and its reader BRD4 (bromodomain protein) co-enriched at Ezh2; conditional BRD4 knockout in injured mouse arteries reduced H3K27me3 and its writer EZH2, which positively regulated another pro-IH chromatin modulator UHRF1. Thus, results uncover injury-induced loci-specific H3K27me3 redistribution in the epigenomic landscape entailing BRD4→EZH2→UHRF1 hierarchical regulations. Given that these players are pharmaceutical targets, further research may help improve treatments of IH.

Penjadwalan Pemetikan Teh dengan Model Programa Dinamis yang Mempertimbangkan Kualitas Pucuk
Authors: Cucu Wahyudin  , Yudhi Sodikin Ma'ruf
Published: February 2022

Penerapan aturan gilir petik di PPTK Gambung berlaku untuk semua blok yaitu berkisar antara 9-10 hari sekali. Hal ini menjadi salah satu sebab sering tidak terpenuhinya rencana produksi baik dari aspek kuantitas maupun kualitas teh, karena perbedaan ketinggian tempat dan umur pangkas diantara blok-blok kebun tersebut, menyebabkan kecepatan pertumbuhan pucuk teh juga berbeda-beda. Oleh karenanya diperlukan aturan gilir petik yang sesuai dengan pertumbuhan pucuk teh.

Untuk itu penelitian ini dilakukan dengan tujuan untuk menyusun jadwal pemetikan yang dapat meminimalkan biaya pemetikan teh. Optimasi penjadwalan ini dilakukan dengan cara pemilihan blok pemetikan secara tepat, sesuai pola penurunan kualitas pucuk.

Dua tahap pemecahan masalah diperlukan untuk memecahkan masalah di atas. Tahap pertama adalah pencarian pola penurunan kualitas pucuk yang sesuai ketinggian tempat dan umur pangkas masing-masing kelompok blok kebun. Selanjutnya pola penurunan kualitas pucuk tersebut digunakan untuk menentukan biaya penurunan kualitas pucuk teh, dan biaya akibat tersisanya pucuk teh di kebun, yang merupakan komponen dari total biaya pemetikan selain biaya langsung pemetikan. Tahap yang kedua adalah menyusun model penjadwalan pemetikan yang dapat meminimalkan total biaya pemetikan dan penurunan kualitas pucuk teh. Formulasi matematik yang dipakai adalah programa dinamis, model ini merupakan modifikasi dari model persediaan produksi dinamis.

Gas produser stabil terbakar di burner, tetapi hanya mampu membuat udara panasdi unit pengering teh hingga 92oC (suhu target 100oC 120oC). Diperkirakan tidak tercapainya suhu target disebabkan kapasitas gasifier kurang besar, sehingga gas produser yang disuplai kurang dan pembakaran di burner selalu dalam ekses udara yang tinggi.

Beberapa faktor gasifikasi yang diperkirakan mempengaruhi proses, antara lain: 

a. batubara pecah menjadi partikel lembut, menyebabkan penurunan tekanan yangmenghambataliran,

hambatan aliran di ruang reduksi terjadi akibat pelelehan abu, menyebabkan penyumbatan

aliran maupun penutupan arang, sehingga sulit bereaksi,

c.kandungan tar masih banyak, karena tidak adanya scrubber yang dipasang di depan pendingin. 

Untuk menurunkan temperatur proses gasifikasi yang masih tinggi dan pelelehan abu diatasi dengan air yang disemburkan dalam bentuk kabut (spray) dalam daerah oksidasi melalui pemasangan pocker, penguapan air menyebabkan produksi hidrogen tinggi. Modifikasi lanjut difokuskan pada reaktor gasifikasi berupa perombakan throat (zona reduksi) untuk menurunkan temperatur proses dan meningkatkan pasokan gas hasil.
Kültürün metinler yoluyla aktarımı bağlamında Türkçe ders kitaplarında geleneksel çocuk oyunları

Published: February 2022

Bu çalışmanın amacı, ilköğretimin Türkçe ders kitaplarında yer alan metinlerde, önemli bir kültür unsuru olan geleneksel çocuk oyunlarına ne ölçüde yer verildiğinin tespit edilmesidir. Bu amaçla araştırma, tarama çalışması şeklinde düzenlenmiştir. Doküman inceleme yöntemiyle toplanan araştırmanın inceleme nesnelerini, MEB tavsiyeli olarak ilkokul ve ortaokul Türkçe derslerinde okutulan kitaplarındaki metinler oluşturmaktadır. 2016-2017 öğretim yılında okullarda eğitim gereci olarak kullanılan üçüncü, dördüncü ve beşinci sınıf Türkçe ders kitaplarının metinleri incelenmiştir. İnceleme ana metinler ve serbest okuma parçaları ile görseller üzerinden gerçekleşmiştir. Elde edilen veriler nitelik ve nicelik açısından değerlendirilmiştir. Değerlendirme, oyun adı, oyun görseli, oyun tekerlemesi, oyun gereci, oyun içeriği gibi kriterler üzerinden yapılmıştır. İnceleme sonucunda, kitap yazarlarının dil becerilerini öne çıkarmaya çalıştıkları, çocukları milli bir kültür unsurları ile buluşturmayı hedeflemedikleri belirlenmiştir. Yazarlar, metni sadece bir araç olarak kabul etmekte ve metnin çocuğa aktarabileceği mesajları dikkate almamaktadırlar. Metin seçimlerinde oyun çağında olan ve oynayarak mutlu olabilecek 7-12 yaş aralığındaki çocuklara hitap edildiği göz ardı edilmiştir. Bu dikkatsiz ve özensiz yaklaşım neticesinde, çocuğun dünyasına doğrudan ulaşma fırsatı kaçırıldığı gibi, metinlerin kültür aktarıcılığı fonksiyonu da değerlendirilememiştir. Yeterince kitap okuma alışkanlığı kazanamamış öğrencilerin dahi, ders kitaplarındaki metinlerini severek okuduğu dikkate alındığında, bu fırsatın milli bir değer olan ve teknoloji karşısında sürekli küçülen oyunlar adına bir kayıp olduğu gözlenmiştir. Buna göre Türkçe ders kitaplarında geleneksel çocuk oyunlarına daha özenle yaklaşılabilir, genel “oyun” sözü yerine detay verilebilir, görseller hazırlanırken oyunlar daha net bir biçimde yansıtılabilir. Bu şekilde birazcık dikkat ve çaba ile önemli bir kültür unsurunun var olmasına destek sağlanabilir.

Published: February 2022

Kültür, milletlerin kimliğini belirleyen temel unsurdur. Maddi manevi üretimlerin bütünü olarak değerlendirilen kültür, bir milletin millî kimliğini oluşturduğu için o milletin tarih sahnesindeki varlığını sürdürebilmesi, kültürünü gelecek kuşaklara aktarabilmesi ile doğru orantılıdır. Somut olmayan kültürel mirasın yinelenerek yahut yenilenerek aktarımı çeşitli araçlarla gerçekleşebilmektedir. Bu araçlardan biri de kültür aktarımının en alt tabakasında ve ilk aşamasında bulunan çocuklara hitap eden çizgi filmlerdir. Bu çalışmada Kukuli adlı çizgi filmde yer alan yirmi parçanın içeriği ve klipleri somut olmayan kültürel mirası aktarmadaki rolü açısından incelenmiştir. Çizgi filmin içeriğine uygun olarak yerleştirilmiş olan şarkılar / türküler ile bunların kliplerinde yer alan kültürel unsurlar tespit edilmiştir. Çalışmada örneklem ve içerik analizi yöntemi kullanılmıştır. Yapılan inceleme neticesinde ele alınan şarkılarda ve onların kliplerinde kültürün en temel unsuru olan dile ait kalıp sözlerin, atasözü ve deyimlerin, sıklıkla kullanıldığı tespit edilmiştir. Ayrıca halk oyunları, müzik kültürü, halk mutfağı, halk hekimliği, temizlik, aile kültürü, komşuluk kültürü, paylaşımcılık, meslek folkloru, pazar kültürü tespit edilen kültürel unsurlar arasındadır. Somut olmayan kültürel miras değerlerini etkileyen, modern çağın getirdiği dijital kültür ve şehirlileşme/kültür değişimi gibi konular da incelenen şarkı ve kliplerde yer almaktadır. Kültürel unsurları içeren yerli çizgi filmlerin artması ve bunların uluslararası sunumu kültürümüze ait unsurların yurt içinde ve yurt dışında etkin bir biçimde aktarımını sağlayacaktır.
Freud ve Jung ışığında masal ve psikanaliz
Authors: KARABULUT Merve
Published: February 2022

Sözlü ve yazılı geleneğin bir parçası olan masallar nesilden nesile aktarılarak günümüze kadar ulaşır. Bir bilinç ürünü olan ve bilincin tüm sırrını himaye eden masallar derinlemesine analiz edilmeyi beklemektedir. Bilinçten türediği için ister istemez bilinçdışı özellikleri bünyesinde barındıran masalların analiz edilebilmesi için, farklı disiplinlerin bakış açılarına ihtiyaç duyulmaktadır. “Masal ve Psikanaliz” adlı bu çalışmada masalların içerdiği psikanalitik öğelerin çözümlenebilmesi için uygulanan psikanalitik bakış açısı açıklanmaya çalışılmaktadır. Farkında olmadıklarımızın farkına varmamızı sağlayan bu yöntemde, adını duyuran Freud ve Jung olmak üzere çalışmamızda bu iki psikanalistin öğretileri esas alınmıştır. Bu kuramcılar edebi metinleri rüyalara benzeterek masalların da rüyalar gibi birçok bilinçdışı öğeyi barındırdığının ve bunların aynı rüyalar gibi çözümlenmesi gerektiğinin altını çizerler. Biz de buradan hareketle çalışmamızda masalları psikanalitik yöntemle inceleme söz konusu olduğunda, Freudyen ve Jungçu bakış açıları ile masalların nasıl çözümlenebileceğini vermeye çalıştık. Freud’un ve Jung’un rüya çalışmalarını ayrıntılı bir şekilde ele alarak masallara da aynı şekilde uygulanabileceği konusunda detaylı bilgi verdik ve her iki kuramcının birbirlerinden ayrıldığı yönlere dikkat çektik.
Çağ romanı (Zeitroman) kavramına dair genel bir değerlendirme
Authors: GENÇ Hatice
Published: February 2022

Bu makale, çağ romanı türüne kavramsal ve kuramsal açıdan yaklaşarak anlamını ve gerçekliğin yer aldığı diğer roman türleriyle ortak ve ayrılan noktalarını ortaya koymayı amaçlamaktadır. Çünkü roman kavramının tanımına dair belirsizliklerin olması gibi içerik, biçim ve üslup gibi unsurların belirlediği roman türleri arasında da bir takım belirsizlikler yer almaktadır. Bir romanın birden fazla roman türü altında anılması bu duruma örnektir. Özellikle tarih ve edebiyat, geçmiş ve roman, kurmaca ve gerçeklik ilişkisi söz konusu olduğunda birbirlerinin sınırlarına dâhil olan roman türleri ortaya çıkmaktadır. Okuyuculara tarihin, dönemin ve toplumun panoramasını çizen oluşum romanı, tarihsel roman, gezi romanı, çağ romanı, toplumsal roman, aile romanı ve nehir romanı şeklinde farklı adlandırılmalara sahip romanlarda ortak nokta uzak/yakın geçmişte yaşanmış ya da o an cereyan eden olay ve olgulardır. Çalışmamızın konusu özellikle yakın tarihi konu edinen çağ romanı üzerine olduğu için bu roman türünün tanımı, felsefi alt yapısı, tarihsel gelişimi ve diğer roman türleriyle olan bağlantısı ele alınacaktır.

This study aims to develop mathematical equations used in Wright’s method to predictkinematic viscosity of liquid-binary mixture consisting of base oil and additive. The equationis developed by addition of specific constants (αi and αc), representing interaction ofeach component in the mixtures. Evaluation is done using 70 empirical data from 35 samplesderived from liquid blending of 4 types of base oils (B.1, B.2, B.3 and B.4) and olefincopolymers (OCPs), varied in the range of 5-30 % of weight. Kinematic viscosity is measuredat 40oC and 100oC using a cannon automatic viscometer series 2000 (CAV 2000)according to ASTM method D 445. Validation of the equation (Developed-Wright’s method)is performed over all of liquid-binary mixtures of base oil-OCPs, and the accuracy isindicated by percent average absolute deviation (%AAD). The results show that the additionof specific constants could minimize the deviations of estimated values. The averagedeviation of Developed-Wright’s method on kinematic viscosity estimation at 40oC and100oC becomes 2.056 % and 1.917% respectively, lower than Wright’s method which are8.341 % and 14.696%; meanwhile the maximum deviation reaches 5.821 % and 4.657%,lower than Wright’s method which are 21.256 % and 25.265% respectively. These valuesindicate that the Developed-Wright’s method has better accuracy.
DISCREPANCY OF MCMP DERIVED FROM EXPERIMENTS AND PREDICTION MODELS OF SOME INDONESIAN OIL FIELDS
Authors: Sugihardjo Sugihardjo
Published: February 2022

Most of oil fi elds in Indonesian have been categorized as mature fi elds, since the primary stages of theoil production nearly fi nished. Therefore EOR technology is the only option to rejuvenate those old oil fi eldsto increase the oil recovery. CO2 miscible fl ooding, one of the proven EOR technology, can be implementedin some Indonesia oil fi elds if they fulfi ll the screening criteria for CO2 injection. Laboratory works initiallyshould be carried out to determine some parameters for calibrating the reservoir simulation program. Themost important parameter is MCMP (multiple contact miscibility pressure), this pressure level can be usedto determine the displacement effi ciency of the CO2 injection. Above the MCMP will be more effi cientcompare to below MCMP injection pressure. MCMP is normally can be obtained in the lab by a Slim tubeapparatus. In case there are no oil and gas sample available, some correlations based on the empiricalfi eld data are also available in the literature as well as EOS (equation of state) for predicting MCMP. Somereservoir fl uids MCMP have been evaluated using those three methods. Then, discrepancies were calculatedto compare the results of Slim tube tests, correlations and EOS calculation. Four correlations such as NPC(National Petroleum Council), Cronquist et al, Yellig-Metcalfe, Holm-Yosendal and one EOS modeling ofPeng-Robinson (1978) have been proposed to predict the MCMP fourteen reservoirs. Moreover, those MCMPwere also run using Slim tube. Holm-Yosendal correlation has nine reservoirs and secondly Yellig-Metcalfemethod possesses six reservoirs with discrepancy below 10% compare to MCMP obtained from Slim Tubetests. While the other methods are not appropriate as well as Peng-Robinson EOS modeling without anylaboratory data for calibration.
POROSITY VERSUS DEPTH CHARACTERISTICS OF SOME RESERVOIR SANDSTONES IN WESTERN INDONESIA
Authors: Widarsono Bambang
Published: February 2022

Porosity is a petrophysical property that always draws attention due to its central role in determiningstorage capacity of hydrocarbon reservoirs. Accuracy for predicting porosity in reservoir affects much ofmany petroleum production related activities. Accordingly, various attempts have been devoted to study andmodel rock porosity including its relation with depth. In this study porosity data from as many as 4654 coresamples (1773 full-diameter core plugs and 2881 sidewall core samples) is used. The core samples were takenfrom 549 wells in 222 fi elds/structures located in eight producing sedimentary basins in western Indonesia.Main results of the study are facts that existing porosity-depth models derived from data obtained from otherregions are not usable for Indonesian cases, and therefore porosity-depth models are established for theeight sedimentary basins. It is hoped that these models can contribute signifi cantly to the understanding ofrock porosity trends with depth in western Indonesia.
