Authors: Hamid Abdul , Trisakti Samsol
Published: December 2018

Operasi penyemenan merupakan salah satu bagian dari pekerjaan operasipemboran. Operasi penyemenan cukup penting dilakukan agar tidak terjadimasalah-masalah pada operasi pemboran. Maka dari itu, untuk menghindarimasalah pada pemboran, perlu dilakukan pengujian atau percobaan dilaboratorium sebelum melakukan operasi penyemenan di lapangan. Hal iniberfungsi untuk mendapatkan formulasi komposisi yang optimum, sehingga dapatberfungsi dengan baik ketika pelaksanaan di lapangan.Pada percobaan ini akan diamati bagaimana pengaruh penambahan additifcement dispersant terhadap sifat fisik semen pemboran, yaitu waktu pengerasan(Thickening Time) dan kuat tekan (Compressive Strength) pada semen kelas E dankelas G, sehingga akan diperoleh gambaran seberapa besar komposisi cementdispersant yang optimal yang harus ditambahkan pada semen pemboran. Additifcement dispersant yang digunakan adalah CFR-2, yang berasal dari HalliburtonOilfield Service Company.Dari beberapa kali percobaan thickening time, terlihat bahwa nilai titikminimum dan maksimum semen kelas kelas G lebih besar daripada semen kelasE, yaitu pada titik minimum mencapai 65 mm/menit dengan penambahankonsentrasi CFR-2 sebesar 2%, sementara pada titik maksimum mencapai 150mm/menit dengan penambahan konsentrasi CFR-2 sebesar 4,5%. Hal inidikarenakan, additif CFR-2 memang lebih cocok untuk sumur-sumur yangdangkal, yang hanya memerlukan thickening time yang tidak lama.Sementara untuk percobaan compressive strength, didapat bahwa nilaicompressive strength Semen Kelas E lebih besar daripada Semen Kelas G. Hal inidikarenakan, Semen Kelas E memang didesain untuk kondisi sumur yang dalam,mempunyai tekanan dan temperatur yang tinggi, dan berada di kedalaman 10000hingga 14000 ft. Berbeda dengan Semen Kelas G yang hanya semen dasar saja,yang digunakan hanya untuk kedalaman 0 (permukaan) hingga 8000 ft saja. Nilaicompressive strength Semen Kelas E mencapai 4225 psi, pada suhu 80ºC,sementara untuk Semen Kelas G hanya 3850 psi, pada suhu 27ºC, walaupunkeduanya sama-sama dilakukan penambahan additif CFR-2 sebanyak 2%.

Pemboran berarah di Indonesia diperlukan untuk menjawab tantangan dari build-up bagian 8.5in dilakukan dengan menggunakan teknik kerekayasaan. Tantangan tersebut termasuk kebutuhan High Dogleg dengan Dogleg severity(DLS) 9o/100ft sampai 11o/100ft, panjang interval lapisan shale yang reaktif, kualitas lubang bor, kendali lintasan, pembersihan lubang dan pemasangan casing liner. Semua tantangan tersebut dapat memengaruhi pembengkakan Authorization For Expenditure (AFE) sumur dan pada kasus yang lebih ekstrim maka akan dapat mengakibatkan hilangnya satu sumur. Jenis perencanaan sumur telah didesain untuk pemboran vertical di bagian 12.25in, kemudian build pada bagian 8.5in dari vertikal ke inklinasi 90o dengan buildup rate 11o/100ft untuk memasuki zona reservoir.Kerjasama antara operator dan perusahaan penyelenggara pemboran berarah memberikan kemudahan bagi para insinyur pemboran untuk mengahadapi tantangan conventional steerable motor assemblies. Bagian 12.25in dibor vertikal dengan menggunakan motor dan bagian 8.5in dibor dengan menggunakan Rotary Steerable System (RSS). Teknologi ini ditujukan untuk membandingkan rasio penetrasi menggunakan motor dan RSS. Solusi ini memudahkan operator untuk membor bagian 8.5in dengan aman dan efisien tanpa hambatan, selama proses mengebor dan pemasangan casing, juga dapat menghemat waktu sampai dengan 3 hari dari perencanaan. Teknologi baru ini mebuktikan bahwa ada kemungkinan untuk membor dengan Dogleg Severity (DLS) sampai 17o/100ft dengan putaran penuh. Rasio penetrasi pada bagian ini juga tidak membutuhkan sliding.

Authors: Simorangkir P
Published: December 2018

LONG LEG JACKUP RIG DAN PEMANFAATANPemboran dilepas pantai pada umumnya dilakukan dengan perangkat pemboran lepas pantai yang dikenal dengan istilah Mobile Offshore Drilling Unit (MODU). Ada beberapa macam MODU yang lazim dikenal yaitu Jack Up Drilling Rig, Drillship, Semi Submersible Rig dan Tender Assist Platform Rig.Untuk pemboran dilepas pantai dengan kedalaman laut 100 meter seperti di lapangan lepas pantai “Natuna”, dapat dipergunakan jenis Semi submersible Rig, DrillShip ataupun Long Leg Jack Up Drilling Rig. Dilihat dari aspek biaya dari ketiga jenis rig ini, maka yang paling murah dan cocok untuk daerah lepas pantai dilaut Natuna ini adalah jenis Long Leg Jack Up Drilling Rig, yang memiliki kaki yang panjangnya dapat mencapai kedalaman laut tersebut. Jenis mobile rig ini adalah yang termurah dari dua jenis mobile rig lainnya.Dengan menggunakan Long Leg Jack Up Drilling Rig ini akan dapat dilakukan pemboran beberapa sumur pengembangan dilapangan minyak didaerah lepas pantai Natuna itu dengan menggunakan Drilling Template sebagai tempat duduknya Subsea Well Head dan Christmas Tree. Dengan demikian maka tidak perlu digunakan Subsea Blow Out Preventer (BOP), yang membutuhkan waktu yang lama dan rumit pemasangannya. Sebagai gantinya dapat digunakan BOP yang lazim dipergunkan pada operasi pemboran didarat (Onshore),.yang posisinya berada diatas permukaan laut .Untuk menghemat biaya mobilisasi rig dari pemboran satu sumur ke sumur lainnya, maka pemboran sumur pengembangan dilepas pantai ini dapat dilakukan dengan cara menggeser (skid) rig pada landasan yang tersedia di Jack Up tersebut, sehingga beberapa sumur dapat dibor dari lokasi dimanaLong Leg Jack Up Drilling Rig tersebut berdiri, sesuai dengan slot yang terdapat pada Drilling Template yang digunakan. Dapat terdiri dari 3slot, 4slot, atau bahkan lebih, tergantung dari luas penyebaran dari resevoir hidrokarbon yang akan diproduksikan. Biasanya salah satu dari beberapa sumur yang akan dibor melalui slot di Drilling Template ini adalah sumur vertkal dan selebihnya adalah sumur berarah atau directional well.

ANALISA DAN UAPAYA DALAM MENGATASI PIPA TERJEPIT PADA PEMBORAN SUMUR X LAPANGAN Z
Authors: Hamid Abdul
Published: December 2018

Operasi pengeboran yang dilakukan tidak selalu berjalan dengan lancar seperti yang diharapkan. Adakalanya terjadi masalah-masalah yang mengganggu operasi pemboran dan akan membuat kerugian. Salah satu permasalahan yang terjadi pada operasi pemboran yaitu pipa terjepit (Stuck Pipe). Penyebab terjepitnya rangkaian pipa bor pada sumur X ini dianalisa dari beberapa aspek yaitu aspek lumpur pemboran, aspek formasi, aspek perhitungan tekanan hidrostatik, formasi, dan perbedaan tekanan. Setelah dilakukan analisa terhadap beberapa aspek tersebut ternyata penyebab terjepitnya rangkaian pipa bor pada sumur X ini adalah diffrential pressure akibat tingginya density sehingga membuat rangkaian drill string menempel pada dinding formasi. Dari analisa tersebut penyusun menyimpulkan bahwa terjepitnya rangkaian pipa bor pada sumur X ini diakibatkan oleh faktor diffrential sticking. Pada sumur X ini metode-metode yang digunakan untuk mengatasi masalah pipa terjepit adalah dengan jar-down & up, WOP ( work on pipe) secara berulang-ulang, penggunaan hi. Vis & low vis dan yang terakhir menggunakan metode perendaman. Permasalah pipa yang terjepit pada sumur X ini diselesaikan dengan menggunakan metode perendaman fluida (spotting fluid) yaitu dengan menggunakan Black Magic dan usaha tersebut berhasil. Analisa penentuan titik jepit dan usaha pelepasannya dilakukan dengan beberapa tahap, diantaranya pembacaan grafik FPIT (Free Point Indicator Tool) untuk menentukan letak titik jepit, perhitungan letak titik jepit secara manual, perhitungan jumlah volume fluida perendaman yang akan digunakan, dan jumlah stroke pompa yang dibutuhkan untuk memompakan fluida perendaman. Pelaksanaan perendaman fluida dilakukan sebanyak tiga kali dengan total volume fluida perendaman sebanyak 125 bbl dan jumlah stroke pompa sebanyak 1068.376 stroke.

Now days, one of the greatest challenges in gas development is transport the fluid especially multiphase fluid to long distances and multiphase pipeline to sell point. Yet, a challenge to transport multiphase fluid is how to operate the systemsin operating a long distance, large diameter, and multiphase pipeline.The operating system include how to manage high liquid holdup, mainly built during low production rate (turn down rate) periods especially during transient operations such as restart and ramp-up, so that liquid surge arriving onshore will not exceed the liquid handling capacity of the slug catcher. The objective of this research is to predict liquid trapped in pipeline network by analysis turn down rate in order to determine minimal gas production rate for stable operation. This research was carried out by two steps: Simulation Approach and Optimization Techniques. Simulation approach include define fluid composition and built pipeline network configuration while optimization technique include conduct scenario for turn down rate. The fluid composition from wellhead to manifold is wet gas. First scenario and Second scenario of turndown rate yield minimum gas rate for stable operation. The pipeline has to be operated above 600 MMSCFD from peak gas production rate is 1200 MMSCFD (A-Manifold Mainline) and 60 MMSCFD from peak gas production rate is 150 MMSCFD for D-Manifold Mainline.

Published: December 2018

Panas bumi merupakan sumber energi terbarukan yang sangat potensial untuk dikembangkan di Indonesia. Potensi energi panas bumi Indonesia tercatat 28.579 MW, namun baru termanfaatkan untuk pembangkit listrik sekitar 1.712,5 MW. Salah satu kendala terbesar di dalam pengembangan panas bumi untuk pembangkit listrik adalah tingkat keekonomian tarif listrik panas bumi. Tarif keekonomian yang ditetapkan pemerintah tidak selalu dapat menjamin keekonomian proyek listrik panas bumi yang ada. Paper ini mencoba melihat keekonomian tarif listrik panas bumi yang terbaru ditetapkan pemerintah. Simulasi perhitungan dilakukan untuk menghitung keekonomian proyek listrik panas bumi di suatu wilayah. Indikator keekonomian yang digunakan adalah Net Present Value (NPV), Internal Rate of Return (IRR), dan Pay Out Time (POT). Dari simulasi perhitungan yang dilakukan, ditemukan bahwa untuk dapat mencapai tingkat keekonomian yang layak perlu ada penyesuaian tarif listrik panas bumi yang ada.
ANALISIS PENGARUH STIMULASI KOH TERHADAP PENINGKATAN LAJU ALIR PRODUKSI SUMUR SIB 1, SIB 2 DAN SIB 3
Authors: Novrianti Novrianti , Rita Novia , Yulia Era
Published: December 2018

Penurunan laju produksi merupakan salah satu dampak yang dapat terjadi akibat adanya kerusakan formasi disekitar lubang sumur. Kerusakan formasi pada sumur yang menjadi objek penelitian pada sumur SIB 1, SIB 2 dan SIB 3 disebabkan oleh clay yang mengembang. Stimulasi KOH dilakukan untuk meningkatkan kembali produksi sumur SIB 1, SIB 2 dan SIB 3. KOH dipilih karena KOH dapat menstabilkan clay sehingga pori-pori yang terhalang oleh clay swelling dapat mengalirkan kembali fluida sehingga meningkatkan kembali laju alir produksi. Penelitian ini bertujuan untuk menganalisis keberhasilan dan peningkatan laju alir produksi setelah pelaksanaan stimulasi KOH. Analisis keberhasilan stimulasi KOH dapat diketahui dengan membandingkan laju alir produksi minyak (Qo), productivity index (PI), dan kurva inflow performance relationship (IPR) sebelum dan sesudah stimulasi KOH. Pelaksanaan stimulasi KOH berhasil pada sumur SIB 1, SIB 2 dan SIB 3. Hal ini ditandai dengan adanya peningkatan laju alir produksi minyak dan productivity index (PI). Peningkatan laju alir produksi minyak pada sumur SIB 1 adalah 227.8 %, SIB 2 adalah 111.86 % dan SIB 3 102.9 %. Sedangkan peningkatan nilai productivity index (PI) pada sumur SIB 1 adalah 96.3%, SIB 2 40.86% dan SIB 3 24.05%. Q max sumur SIB 1 meningkat 99.1 %, SIB 2 40.68% dan SIB 3 meningkat sebesar 24.18%.

Published: December 2018

Dalam operasi pemboran, lumpur pemboran memainkan peranan yang sangat penting karena memiliki fungsi-fungsi yang tak tergantikan. Pada pelaksanan operasi pemboran sumur x lapangan y ini menggunakan lumpur Synthetic Oil Base Mud dan KCL Polymer selama pemboran berlangsung, sifat dan rheology lumpur pemboran harus di perhatikan dan dipertimbangkan kondisi serta karateristik dari formasi yang akan di bor. Adapun penyebab terjadinya masalah masalah tersebut adalah disebabkan karena factor formasi yang mempunyai permeabilitas yang cukup besar sehingga memungkinkan terjadinya masalah hilangnya lumpur. Seperti adanya formasi yang mengandung gua-gua (cavernous formation), formasi yang mengandung rekahan-rekahan secara vertical maupun horizontal. Dalam menganalisa hal ini akan mengakibatkan kerugian baik dari segi waktu, finansial , maupun kesalamatn kerja.nOleh karena itu,sebelum proses pemboran dilaksanakan perlu dibuat sebuah perencaan yang matang untuk penenruan program lumpur. Perencaan diantaranya berkaitan dengan jenis lumpur, densitas, viskositas, daya agar, derajat keasaman, laju tapisan dan lain-lain yang disesuaikan dengan lithology tiap lapisan formasi yang di tembus. Perencanaan tersebut juga mencakup analisa potensi permasalahan yang akan dihadapi pada tiap lapisan formasi beserta solusi untuk mengantisipasinya. Namun demikian, pada saat pelaksanaanya sangat umum terjadi beberapa permasalahan di luar analisa tersebut. Dari suatu pendesaianan lumpur diharapkan penggunaannya dapat mengoptimalkan kegiatan pemboran dengan biaya serendah mungkin untuk menekan biaya per barrel nantiSystem lumpur Sythetic Oil Base Mud adalah disperse mud dan biasanya berbiaya lebih mahal , sedangkan lumpur KCL polymer adalah lumpur non disperse yang biasanya lebih murah. Melihat hambatan yang terjadi pada saat pemboran yang berlangsung yaitu adnaya gumbo, shloughing shale, differential pressure sticking, lost, terjepit pipa, swelling clay, partial lost, lumpur Synthetic Oil Base mud dapat mengatasi masalah di atas. Kejadian hilang lumpur dapat diakibatkan oleh beberapa sebab, seperti : kondisi formasinya, dapat menimbulkan kick dan blow out apabila tekanan hidrostatik kolom lumpur dalam sumur turun dan tidak segera di tanggulangi. Meskipun jika dilihat dari segi biaya meskipun Synthetic Oil Base Mud lebih mahal dari KCL Polymer lumpur tersebut dapat digunakan kembali atau dilakukan treatment pada saat digunakan berbeda dengan KCL Polymer dan dapat mengatasi masalah di atas. Pada penulisan paper ini akan dievaluasi sejauh mana pemakaian lumpur Synthetic Oil Base Mud lebih dan KCL Polymer efektif dalam mengatasi permasalahan-permasalahan di formasi shale yang sangat reaktif.

O objetivo deste artigo é discutir a relação de afinidade nos pensamentos de Weber, Adorno e Horkheimer, com relação ao desencantamento do mundo. Em vista desse objetivo, o percurso da investigação tomará como pedra de toque a questão da racionalização ocidental para demonstrar que, mesmo percorrendo caminhos distintos para apreender os pressupostos teóricos do mundo moderno, a conclusão de ambos sobre os destinos dessa sociedade resguarda assimetria, sobretudo no que diz respeito às consequências do processo de racionalização para a religião. Julgamos que a tematização dessa afinidade é importante porque pode ajudar na compreensão do problema da secularização e da crise de sentido na contemporaneidade.Palavras-chave: Racionalização, Modernidade e Identidade e Religião.Abstract: The objective of this article is to discuss the affinity relationship present in Weber, Adorno and Horkheimer's thoughts regarding the disenchantment of the world. With this intention, the starting point will be the occidental rationalization to demonstrate that even taking distinct paths to learn the theoretical assumptions of the modern world, the conclusion of both regarding society's fate cover asymmetry, above all with respect to the consequences of the process of religion's rationalization. We believe that this affinity subject is important because it can help comprehend the secularization problem and the meaning crisis in contemporaneity.Keywords: Rationalization, Modernity and Identity and Religion.Enviado: 08-10-2018 - Aprovado e publicado: 12-2018
DOM PAULO DE TARSO CAMPOS E A VINDA DO PADRE JOSÉ COMBLIN AO BRASIL

Published: December 2018

Ao se pensar na presença missionária de padres e mesmo religiosos, religiosas e leigos no Brasil, vem sempre o questionamento sobre o que motiva estas pessoas a saírem de suas terras a fim de anunciarem a Boa Nova de Jesus. Quando nos deparamos com a vinda de José Comblin e seus dois companheiros, padres, doutores, para o Brasil, este questionamento é ainda mais alarmante haja vista que, para muitos, e mesmo para eles, não ficara muito claro as intenções do bispo de Campinas, Dom Paulo de Tarso Campos, ao trazê-los para sua Diocese.

Authors: Elmazi Erida
Published: December 2018

This paper deals with the issue of school leadership as one of the main priorities of education policy and focuses on the role, importance it has mainly on teacher’s job satisfaction. It tends to highlight the influence of the school leaders’ style in the pre-university education context. Two dimensions of leadership conceptualization are underlined in this study: the transformational and transactional leader. Teacher job satisfaction is often considered as an important aspect in their performance and productivity. In addition leadership style is considered one of the major influences affecting the job satisfaction of the teachers. The scope was to study the relationship and correlation between the style of the principals and job satisfaction of teachers. Various research techniques, primary and secondary data sources have been used to carry out this study, which are intertwined with one another. As a source of primary data were used two surveys, one for evaluating the principals’ style of leadership and the other one for measuring job satisfaction of the teachers. The sample consisted in 5 teachers from 25 high schools in Albania and Kosovo. There is evidence from the findings that transformational leadership has significant relationship and it has beneficial effects on teacher job satisfaction. These leaders transform, inspire, and empower followers by creating changes in their goals, values, needs, beliefs and aspirations.
The Role of the Family in the Education of Children in Conflict with the Law: Empirical Evidence from Albanian Context
Authors: Zenelaga Dr. Brunilda , Hamzallari Blerina
Published: December 2018

A child is considered in conflict with the law when he/she has committed or has been accused of committing an offence (UNICEF, 2006). According to local context, a child can also be in conflict with the law, when it is taken up by the justice system for minors or for adults, due to the alleged dangers faced by the child in view, or behavior or environment (IDE, 2016:2). The family is a primary agency that influences the child socio-psychological formation. In the case of children in conflict with the law, on one hand family can contribute on creating causes of antisocial and deviant behaviors of children, but on the other hand, it can be an important factor for rehabilitation and correction of the children attitudes.Recently, in Albania, children in conflict with the law have been in center of the attention of policymakers and researchers, but very few of them have explored in depth the role that the family plays on the education of children in contact with the law. This paper aims to fulfill that gap of researches in Albanian context.The methods used to gather data are based on: (a) the use of the secondary data such as international and national literature about the topic, researches with the focus on children in conflict with the law, statistics and other data from different Albanian institutions; (b) the use of the primary data taken from the interviews with experts who work in Probation Service in Albania, school psychologist, experts and professionals in prisons etc. The study revealed that the role of the family is crucial, especially for the children in conflict with the law. Empirical evidence from Albanian context shows that children in conflict with the law came mainly from families with socio - economical problems and/or lack of the attention to the education of the children. The collaboration of the family with other socialization agencies such as schools etc., can be an effective way for the correction of the attitudes of this category of children.
Leftization of Education in South Korean Society Centering Around the Authorized Textbooks
Authors: Kim Bok-rae
Published: December 2018

In South Korea, education is no longer a place for learning, but a base for preparing ideological warriors, due to left-wing ideology education and fervent and conscientious teachers’ union and strong left-leaning media. Since left-wing president Moon took office in 2017, omnidirectional “leftization” of education is ongoing in society. According to Prof. Chul-hong Kim, the current left-leaning “authorized” textbook system strenuously inculcates students with the appropriateness of materialistic historical views. A high school student engaged in the protest against the campaign of “state-designated” textbooks says at a press interview, “I’m a proletarian class. It’s only the proletarian revolution that can change our social structure and its fundamental contradiction.” For reference, there are three kinds of textbooks: (1) state-designated textbook published by state (so, its copyright belongs to state), (2) authorized textbook published by private publishing companies, on the condition of passing through the government screening system (inviting criticism for its “poor screening”), (3) free-published textbook left entirely to the private sector without any state intervention. Prologue The second authorized textbook system is a “compromise” plan between state-led and privately-led textbooks. The main motive for adopting authorized textbooks (from previous state-designated textbooks) was to introduce “diversity of views and opinions” in Korean education, but a conservative journalist Gap-je Cho concluded - from analyzing 14 authorized history textbooks - that “promoting educational diversity” by authorized textbook system ended in failure. Because a great majority of left-wing professors and teachers take part in writing historical textbooks on the basis of Marxist class struggle theory: that is, Koreanized “popular view of history” or populism-based historical perspective (&x6C11;&x8846;&x53F2;&x89C0;). These authorized textbooks are adopted by almost 99% of high schools across the country. Moreover, they tend to implant one “monolithic” idea (historical materialism) in the consciousness of young students. According to Cho, the authorized textbook system mired in controversy is degraded into a “certificate” of anti-state, pro-communist education, in place of diversity.1

Authors: Murtezani Lulzim
Published: December 2018

This is an academic-research paper consisting of two parts: a theoretical and an empirical one. The theoretical part defines the conceptual basis, i.e. the frames of the research project. This means that it primarily deals with some relevant assumptions, such as the personal traits in the context of the academic accomplishments of the students that attend courses for teachers and educators. We conducted an empirical research to determine the role of these components. We opted for the technique of a non-probabilistic research of the sample. It consists of 115 students attending the first cycle of studies at the faculties of pedagogy. We used Eysenck’s Personality Questionnaire (EPQ) as an instrument to measure the following traits: neuroticism – stability, extroversion – introversion, and psychoticism. A simple one-way ANOVA and Kruskal-Wallis tests were used to process the data. The result analysis led to the following conclusions: 1. The students differ in the academic accomplishments based on the variable of neuroticism; and 2. The students differ in the accomplishments based on the variable extraversion. We also suggest that other researches in this scientific area are conducted for a detailed analysis of the relation between the personality traits and the academic accomplishments.
Technology as a Motivational Factor in Foreign Language Learning
Authors: Panagiotidis Panagiotis
Published: December 2018

It is a common belief that engagement and motivation are crucial factors in learning and especially in language learning. In particular, increasing motivation can lead to the mobilization of students’ personal, cognitive, emotional and behavioral resources and, consequently to better learning results. As digital technology has become more sophisticated, its tools and applications can be used in and outside the classroom, in both formal and informal settings, in order to increase students’ motivation. Amongst the various factors -tools, methods or strategies- that can lead to increased motivation, this paper examines the role of technology as a motivational factor in foreign language learning. The relationship between the use of technological means such as web tools and services, digital games, mobile apps or communication tools and motivation in language learning context, has been studied extensively, with a wide variety of approaches, and within the framework of several language learning applications. In order to determine the real impact of technology on learners' motivation, an extensive literature review focusing on studies that have examined the impact of technology use in language learning and teaching on motivation to learn, has been carried out. Furthermore, this paper discusses the concept of motivation in learning context and the relationship between technology and language learning, summarizes some of the numerous studies and researches on this subject, presents a synthesis of the studies examined, and formulates conclusions and perspectives for effective integration of technology as a motivational tool / factor in language learning context.

Arts, Virtue and Character: Perspectives from Philosophy and Psychology
Authors: Omowumi Ogunyemi
Published: December 2018

: In today’s world, the tendency to live constantly connected to a virtual digital space makes it difficult to have an ambiance that fosters paused reflections. Often times, one needs to make a conscious effort to stop and think if one recognises the importance of reflections for making the deliberated choices needed for self-development. For many people, a break from the frenzy of activities is facilitated by arts, such as narratives and music. Interestingly, more than just means of entertainment, the arts can be important catalysts for learning processes. Ancient philosophers affirmed that music is helpful in education to virtue as it tempers the emotions of a child to raise it towards the good. However, such high regards for art and music in character formation is often forgotten today.From the perspective of contemporary narrative philosophy, each action or choice which builds up into the habit is best understood as part of a continuous narrative. One understands the self better when considering it as the protagonist of a narrative moving from a beginning towards an end, guided by chosen goals which are good for the acting subject. Additionally contemporary psychologists acknowledge the role of the arts in character formation. This conceptual paper brings together ideas from psychology and philosophy in order to explore the role of some forms of art in character development. The appreciation of the on-going construction of the plot of one’s life-story guided by the intrinsic goods that promote human flourishing (including aesthetic experiences), may serve as a foundation for understanding the importance of coherence and unity of life for building character.
The Aspects of National Branding: Conceptual and Theoretical Framework
Authors: Andreja Sršen
Published: December 2018

The concept of countries as brands has been increasingly recognized in the post-modern global world. The terms "national brand" or "country brand" define a symbolic construct, which emphasizes the attractive, unique and sustainable qualities of a nation. This paper argues that the national brand and its competitiveness, based on the new approaches of nation branding using sociological and economic theories and concepts, can establish and communicate a specific image of national identity. This paper presents some empirical findings of a study that investigate Croatian national brand. Nation branding might be obtained by a sustained dialog between government, decision makers, business, cultural and civil community, leaders, and individuals in the society. A country brand, therefore, consists of an identity and image, as a system of signs and codes, where nation branding applies widely used marketing concepts for promoting the country's image and attractiveness. Finally, the paper argues that "national brand" or "country brand“is not just a function individually performed by governments or companies, but an integrated and concerted effort on behalf of all interested stakeholders.
