MANFAAT METODE PENGAYAKAN BASAH BAGI ANALISIS FAUNA DARI SITUS KUTA BAGINDA, KALIMANTAN TIMUR
Authors: Algifary Muhammad Abizar , Mahirta  , Anggraeni
Published: November 2023

. Ekskavasi untuk memperoleh temuan pada situs arkeologi kadang kala mengabaikan aktivitas pengayakan (sieving). Padahal, penggunaan metode pengayakan dalam suatu ekskavasi ditujukan untuk memaksimalkan temuan dan menjawab kelimpahan data. Aktivitas dry dan wet sieving kebanyakan dilakukan dalam penelitian di situs-situs prasejarah, sedangkan di situs-situs masa historis kurang menjadi perhatian. Situs Kuta Baginda abad ke-14 Masehi yang terletak di Kalimantan Timur merupakan situs yang dijadikan contoh bahwa penggunaan ayakan dengan ukuran saringan kecil pada proses ekskavasi berhasil memperoleh temuan yang dapat mengungkap karakteristik pemukiman secara lebih detail. Salah satu temuan arkeologis yang didapatkan dari penggunaan metode pengayakan adalah temuan ekofak fragmen tulang. Proxy tersebut dapat memberikan informasi penting dan komprehensif tentang suatu situs, seperti jenis kegiatan yang telah terjadi dan pola makan penghuni situs. Tujuan penelitian ini adalah pemahaman tentang sumber protein yang mendukung subsistensi masyarakat pada masa pra kerajaan Berau. Penelitian ini memaparkan pentingnya akuisisi data fauna melalui pengayakan basah (wet sieving) dan analisis sisa-sisa osteologi hewan dari hasil ekskavasi Kuta Baginda tahun 2019 dan 2021. Proxy fauna diidentifikasi berdasarkan bentuk dan taksonnya. Kemudian analisis dimulai dengan tabulasi silang number of identified specimens berdasarkan spesies hewan dan bagian kerangka yang paling umum ditemukan dari setiap spesies di situs Kuta Baginda. Interpretasi data terhadap temuan hasil penerapan metode ayakan kering dan basah menunjukkan bahwa sisa-sisa fauna sumber protein yang dikonsumsi komunitas pada masa tersebut berupa babi, unggas, kerang, ikan laut, dan ikan payau, serta pemanfaatan bagian-bagian tubuh fauna untuk kepentingan lain seperti racun ikan.The sieving method is used in an excavation to maximize data collection and to manage the abundance of data. This research aims to understand the protein sources that supported community subsistence during the pre-Berau kingdom period. This research explains the importance of faunal data acquisition through wet sieving and analysis of animal osteological remains from the 14th-century Kuta Baginda site. Faunal proxies are identified based on their shape and taxon. Further, the analysis begins with a cross-tabulation of the number of identified specimens based on animal species and the most common skeletal parts found from each species at Kuta Baginda. Data interpretation of proxies obtained with dry and wet sieve methods in the 2019 and 2021 excavations shows that the remains of animal sources of protein consumed by the community at that time were pigs, poultry, shellfish, saltwater fish, and brackish fish, as well as the use of their parts for other purposes such as fish poison.

Optimisation Techniques for Compact CNN on Embedded Systems for Gesture Recognition
Authors: Bittencourt João Carlos , Conceição de Jesus Rocha Walber
Published: November 2023

Embedded applications are increasingly prevalent in various domains, from consumer electronics to industrial automation and smart cities. With the advances in integrated circuit manufacturing technologies, low-power chips can now execute complex algorithms, including machine learning models. However, the computational constraints of embedded devices require compact and efficient neural network models, as well as software frameworks and optimisation techniques tailored to their hardware resources. This study investigates the implementation of Convolutional Neural Network (CNN) models for gesture recognition on an STM32F4 microcontroller, by exploring the impact of freezing layers, fine-tuning and pruning techniques on pre-trained CNN models. The results demonstrate that fine-tuning and freezing layers improve accuracy by up to 18%. Additionally, freezing layers by 10% and 20% improved the accuracy. Finally, we demonstrate that pruning reduced the model size by 90%, enabling it to perform gesture recognition on small devices. These findings are significant for developing software and optimisation techniques for embedded systems, particularly in the context of the Internet of Things.
Misogynistic Views in Participatory Dictionaries
Authors: KOÇ Çilem Tuğba
Published: November 2023

Like other forms of marginalization, misogyny feeds on negative stereotypes associated with the targeted group. These stereotypes are dominant in society, perpetuated through discourse, and often perceived as normal. Participatory dictionaries, popular sources of information for people from childhood onward, are one of the platforms where online misogyny is produced. Given the influence of these dictionaries, investigating and revealing misogyny in them may require rethinking and questioning the social assumptions about the female sex in the online environment. Though misogyny does not always result in direct violence, it mentally feeds violence against women. Investigating it in online environments is therefore vital, especially in a world where individuals are increasingly becoming socialized and learning judgments about their sex identities in digital spaces. This study aims to uncover discriminatory and misogynistic discourses against women in participatory dictionaries. For this purpose, its examination is conducted using the oldest and most popular dictionaries in Turkey—namely, Ekşi Sözlük (1999), Instela (2004 at ITU-2015 at Instela), Uludağ Sözlük (2005), and İnci Sözlük (2009). A total of 684 entries containing misogynistic elements under the topic of women are analyzed in this study. In line with the purpose of this study, these entries are analyzed using van Dijk’s ideological square technique. Our analysis reveals that discriminatory language is used against women, describing them as creatures or non-human entities through the use of negative adjectives. In addition to direct misogyny, such as insults and belittlement, indirect misogyny is also found among the entries, including victimization and objectification.
Impact of economic sanctions on financing for oil and gas projects in the Russian Arctic
Authors: Flegontov N. A.
Published: November 2023

The article analyzes the impact of the economic sanctions of 2022–2023 on the financing for oil and gas projects in the Russian Arctic. The relevance of the topic is attributed to the importance of developing the Arctic oil and gas potential for the energy sector, which is a pivotal industry for the Russian economy. The Arctic zone contains a significant part of Russian and global hydrocarbon reserves. The economic and political feasibility of their development is increasing amid the resource depletion in the traditional production basins and the shift of energy consumption сenters to the Asia-Pacific countries. The author considers the role of the oil and gas industry in the global and national economy, identifies the specific features of the oil and gas projects in the Arctic climatic conditions, analyzes the main economic sanctions affecting the financing for the projects. The assessment of their impact on the Arctic LNG 2 and Vostok Oil projects is also provided. The research is based on the methods of systemic, statistical and comparative analysis, economic analysis, case method and risk assessment. The author concludes that the imposed sanctions have significantly limited the opportunities for financing for the oil and gas investment projects in the Russian Arctic. However, the impact of sanctions may be quite moderate in the short run, while the lack of financing may lead to a change in the timelines and scale of ongoing projects on the horizon of 5–10 years.
Finland’s approaches to joining NATO
Authors: Alyautdinov M. K. , Popovich I. V.
Published: November 2023

For the region of Northern Europe the beginning of 2022 was marked by an important event — the application of Finland and Sweden for membership in the NATO military alliance. For both countries the move signified the end of decades of the neutrality policy, and the North Atlantic Alliance expansion would be relatively significant for the first time since 2009. One of the main features of Finland’s and Sweden’s process of joining NATO was the desire of both countries’ administrations to achieve the Alliance membership simultaneously. Due to certain difficulties that had risen on the international level and prevented Sweden from becoming a member of the organization swiftly, the Finnish administration made the ultimate decision to join NATO independently from Sweden. The decision was connected with the abandonment of the principle of “special relations” between Sweden and Finland. The approval of the NATO membership bill during its ratification in the Finnish parliament was not unanimous. Several lawmakers spoke out against the country’s integration with NATO. This and other factors testify to the controversial attitude to NATO in the Finnish society. “The Kurdish issue” was among the important aspects of Finland’s North Atlantic Alliance joining process. Prior to 2022 Finland along with Sweden adhered to the position of supporting various Kurdish groups that were recognized in Turkey as terrorist organizations. Finland also took in a lot of Kurdish refugees and provided political asylum to some of them. The Turkish authorities were dissatisfied with those actions hence in May 2022 Turkey blocked the NATO membership application of the Finnish republic. “The Kurdish issue” was not fully resolved, but the sides managed to reach a compromise.
Trade and economic relations between the EAEU member states and the countries of Latin America and the Caribbean at the present stage: the cases of Armenia and Kazakhstan
Authors: Aleksanyan L. M.
Published: November 2023

In the context of a changing world order, the development of regional integration processes is an important trigger for the inclusion of countries in the world economy and increasing the sustainability of national economies. Integration processes contribute to deepening of the interdependence of different countries, as well as to the expansion of the influence of world economic relations on national economic systems. At the same time, tendency towards the erosion of institutions and mechanisms of multilateral (global) trade and the formation of preferential regional and interregional trade agreements (partners in which are often not only individual countries, but also integration blocs), has become one of the characteristic features of modern international economic relations. The Eurasian Economic Union, as an international organization for regional economic integration, makes efforts to expand geographical boundaries of foreign economic ties, with the aim of developing relations with the economic integration groupings and individual countries throughout the world. With the same purpose EAEU member states pay attention to the development of relations with the region of Latin America and the Caribbean (LAC), considering regional countries as promising partners for mutually beneficial cooperation. This article is devoted to the study of trade relations between the countries of the EAEU and Latin America. Special attention is paid to the trade and economic relations of Armenia and Kazakhstan with Latin American countries. The choice of these two states is not accidental, since they are relatively active in the Latin American direction and complement the policy of the Russian Federation aimed at deepening cooperation with the LAC. The author concludes that these countries have the potential for further development of trade and economic relations, the implementation of which requires overcoming, first of all, logistical obstacles and tariff barriers.
Arctic cinema: from horror through dramas and thrillers To Actiоn movies and fiction (Part II)
Authors: Zonn I. S.
Published: November 2023

The article examines Arctic thrillers, action films and fantasy films. Presented kaleidoscope of horror, drama, thriller, science fiction and action films, with all its plot differences, is united by almost a single location, the Arctic north. Against his background, all maginable and unimaginable events occur. It enhances or weakens the role of what is happening with its whiteness, making the viewer’s screen even whiter. This is an artistic space in which characters are placed and actions, are performed. The silence of the Arctic is its action. The films reviewed are extremely different, responding to the spirit of the time when they were filmed. Their placement about genres is conditional since they all have a cinematic hybridity. Each tape combines all kinds of genres under consideration. We tried to correlate a number of films with temporary political-social processes.

Legal institute of preferences: concept, composition and system
Authors: Chornovol Evgeniy Petrovich
Published: November 2023

The author formulates the concept, constitutional and legal basis, composition and system of the legal institution of preferences of the Russian competition law. The relevance of the study is determined by the fact that by now this legal education has not only not been studied in domestic jurisprudence, but is not positioned at all in the doctrine of competition law. Moreover, some legal scholars consider it alien to competition law. The purpose of the study is to substantiate the functioning of a separate legal institution of preferences in the system of competition law, the political and legal basis of which is the constitutional and legal provisions defining the beginnings of the country's market economy and the solution of socially significant tasks of Russian society through the use of the preferential mechanism, which includes two levels of legal forms at the sectoral level norms of international acts and treaties of Russia, regulatory legal acts of the Federation, subjects of the Russian Federation and municipalities of procedural and material order, differentiating into general and special prescriptions, forming its general and special parts. In the process of studying the legal phenomenon of preferences, a dialectical method of cognition was used within the framework of a materialistic approach in combination with private scientific methods of cognition of social and legal phenomena: analysis and synthesis, observations and comparisons, system and framework method, forecasting, planning and modeling. As a result of the conducted research, the fundamentals of the theory of the competitive legal institute of preferences are presented, as well as the positions of denial of the connection of preferences with the regulation and protection of competition among legal scholars and interpretation of the relevant provisions exclusively from the perspective of anticonrurent regulation of the activities of public legal entities are refuted. The provisions and conclusions of the study can be used in the law-making and law enforcement practice of the relevant legal provisions, as well as in the educational process of training lawyers. The novelty lies in the substantive analysis of the regulatory framework for the selective provision by the authorities of public legal entities with the prior consent of the antimonopoly authority of the country to economic entities of preferences as a separate institution of a special part of competition law.The functioning of the competitive legal institute of preferences is based on legal principles that determine its method, tasks and functions.

Published: November 2023

This study aims to determine the multiple roles and constraints faced by single parents of women in the midst of their families. This study used qualitative research methods. Research subjects were taken using a purposive sampling technique. Data was collected through observation techniques, interviews and documentation. The theory used is role theory with the supporting theory of AGIL (Adaptation, Goal, Integration, Latency). It was concluded that the role attached to a mother, namely the domestic role and the role attached to a father, namely the public role, has different challenges and implementation. A single-parent woman carries out both roles simultaneously, there is a division of labor among other family members and some are not. There are several forms of maintenance carried out by a single-parent woman in the midst of her family, which will require a time-consuming process. This is done in order to support the current situation and minimize constraints and conflicts in the family. There are several obstacles faced, most of the obstacles are related to meeting family needs, and giving affection and attention. The concept of AGIL in research is associated with the concept of roles and constraints in carrying out these dual roles.

Published: November 2023

Although regulations regarding child-friendly school policies have been made by the government since 2014. However, the reality is that we often find cases of violence against children in educational institutions covered by social media. Cases of violence that often occur in educational institutions include physical violence, sexual violence, and psychological violence. In this study, researchers were very interested and wanted to research teacher strategies for preventing acts of violence through child-friendly school programs. This aims to map teacher strategies from the results of research on child-friendly schools that have been conducted by several previous researchers. This study uses a qualitative approach with the method of a literature review or literature study. It is hoped that the results of this strategy mapping can be put to good use in the future by educational institutions in Indonesia to implement a child-friendly school program. The results of the study show that educational institutions that have implemented a child-friendly school program have tried to follow the rules by the six standard indicators set by the government. Teachers are required to carry out fun learning, invite students to actively participate, also provide more educational punishments if students make mistakes. Several educational institutions are also innovating by creating literacy activities, clean Fridays, strengthening character education, creating educational content for children through social media, and providing counseling services that students and parents can access.
Non-destructive egg breed separation using advanced VOC analytical techniques HSSE-GC-MS, PTR-TOF-MS, and SIFT-MS: assessment of performance and systems’ complementarity

Published: November 2023

Over the past decade, advanced analytical techniques have been utilized to examine volatile organic compounds (VOCs) in eggs. These VOCs offer valuable insights into factors such as freshness, fertility, the presence of cracks, embryo sex, and breed. In our study, we assessed three mass spectrometry-based systems (headspace sorptive extraction gas chromatography-mass spectrometry; HSSE-GC-MS, proton transfer reaction time-of-flight-mass spectrometry; PTR-TOF-MS; and selected ion flow tube mass spectrometry; SIFT-MS) to analyze and identify VOCs present in intact hatching eggs from three distinct breeds (Dekalb white layer, Shaver brown layer, and Ross 308 broiler). The eggs were sampled on incubation days 2 and 8, to identify VOCs that distinguish breeds irrespective of incubation day. VOC measurements were conducted on 15 eggs per breed by placing them together with PDMS-coated stir bars inside inert Teflon® air sampling bags. After an accumulation period of 2 hours, the headspace was analyzed using PTR-TOF-MS and SIFT-MS, while the VOCs adsorbed onto the stir bars were analyzed using GC-MS for additional compound identification. Partial least squares discriminant analysis (PLS-DA) models were constructed for breed differentiation, and variable selection was performed. As a result, 111 VOCs were identified using HSSE-GC-MS, with alcohols and esters being the most abundant. The PLS-DA models demonstrated the efficacy of breed discrimination, with the HSSE-GC-MS and the PTR-TOF-MS exhibiting the highest balanced accuracy of 95.5% using a reduced set of 11 VOCs and 5 product ion masses, respectively. The SIFT-MS model had a balanced accuracy of 92.8% with a reduced set of 11 product ion masses. Furthermore, complementarity was observed between HSSE-GC-MS, which primarily selected higher molecular weight VOCs, and PTR-TOF-MS and SIFT-MS. A higher correlation was found for compound abundances between the HSSE-GC-MS and the PTR-TOF-MS relative to the SIFT-MS, indicating that the PTR-TOF-MS was better suited to quantify specific compounds identified by the HSSE-GC-MS. Finally, the findings support the presence of VOCs originating from both synthetic and natural sources, highlighting the ability of the VOC analysis systems to non-destructively perform quality control and reveal differences in management practices or biological information encoded in eggs.

Published: November 2023

Mass spectral libraries have proven to be essential for mass spectrum annotation, both for library matching and training new machine learning algorithms. A key step in training machine learning models is having high-quality training data. Public libraries of mass spectrometry data that are open to user submission often suffer from limited metadata curation and harmonization. The resulting variability in data quality makes training of machine learning models challenging. Here we present a library cleaning pipeline designed for cleaning tandem mass spectrometry library data. The pipeline is designed with ease of use, flexibility and reproducibility as leading principles.
Photodriven Ammonia Synthesis from Manganese Nitrides: Photo-physics and Mechanistic Investigations
Authors: Panetti Grace , Kim Junho , Myong Michele , Bird Matthew , Scholes Gregory , Chirik Paul
Published: November 2023

Ammonia synthesis from N,N,O,O-supported manganese (V) nitrides and 9,10-dihydroacridine using proton-coupled electron transfer and visible light irradiation in the absence of a precious metal photocatalyst is described. While the reactivity of the nitride correlated with increased absorption of blue light, excited-state lifetimes determined by transient absorption were on the order of picoseconds. This eliminated excited state manganese nitrides as responsible for bimolecular N–H bond formation. Spectroscopic measurements on the hydrogen source, dihydroacridine, demonstrated that photooxidation of 9,10-dihydroacridine was necessary for productive ammonia synthesis. The transient absorption and pulse radiolysis data for dihy-droacridine provided evidence for the presence of intermediates with weak E–H bonds, including the dihydroacridinium radical cation and both isomers of monohydroacridine radical. Additional optimization of the reaction conditions using catalytic amounts of acridine, resulted in higher rates of the ammonia production from the manganese(V) nitrides due to introduction of a photooxidant.

Published: November 2023

The modification of polymer surfaces using laser light is important for many applications in the nano-, bio- and chemical sciences. Such capabilities have supported advances in biomedical devices, electronics, information storage, microfluidics, and other functional material applications. In most cases, these modifications require high power lasers that are expensive and require specialized equipment and facilities to minimize risk of hazardous irradiation. Additionally, polymer systems that can be easily modified by lasers are often complex and costly to prepare. In this report, these challenges are addressed with the discovery of low-cost sulfur copolymers that can be rapidly modified with lasers emitting low-power infrared and visible light. The featured copolymers are made from elemental sulfur and either cyclopentadiene or dicyclopentadiene—all inexpensive building blocks. The addition of Fe2O3 nanoparticles to the polymer matrix enhanced the rate of modification, enabling polymer ablation at lower laser powers for the dicyclopentadiene-derived polymer, which had a high glass transition temperature. Using a panel of lasers with discreet wavelengths (532, 638 and 786 nm) and powers, a variety of surface modifications could be made on the polymers such as controlled swelling or etching via ablation. The facile synthesis and laser modification of these polymer systems were exploited in applications such as direct laser lithography and erasable information storage.

Science, Technology, Engineering, and Mathematics (STEM) education has been piloted by the Vietnamese Ministry of Education and Training for primary school teachers since 2022. This research aims to evaluate awareness, confidence and the correlation between those variables with the demographic factors of Vietnamese elementary school teachers after nearly a year of implementing integrated STEM teaching. This study used a questionnaire survey method consisting of 30 items on a 5-point Likert scale for 148 elementary school teachers in the Central and Central Highlands of Vietnam. Data was analysed using SPSS software. Descriptive statistics results showed that Vietnamese elementary school teachers have good awareness but lack confidence in STEM-integrated teaching. Correlation analysis showed a positive correlation between teachers’ awareness, confidence, and some demographic factors (educational level, work area). The outcomes of the one-way ANOVA analysis revealed a positive correlation: increased levels of teachers’ education corresponded to heightened awareness and confidence in STEM-integrated teaching. Additionally, teachers located in urban areas demonstrated greater awareness and confidence compared to their counterparts in rural countryside and highland areas.. Some recommendations to increase awareness and improve confidence in teaching STEM integration for Vietnamese elementary school teachers are presented at discuss session.

In an effort to achieve educational goals and improve students' enthusiasm for Physics, it is important to take into account the prior experiences that students bring with them to the classroom. Teachers' exploration of these prior experiences is crucial when implementing the constructivist approach to classroom instruction, as it helps in achieving the desired objectives. Consequently, this research aimed to investigate how the application of cognitively guided instruction influences the attitudes of senior secondary school students towards Physics. The study employed a pretest-posttest control group quasi-experimental design and utilized multilevel linear models for data analysis, considering the hierarchical structure of the data with participants nested at both classroom and school levels. Students’ Attitude to Physics Questionnaire was used to collect data during the study. The study's findings revealed a significant positive impact of cognitively guided instructional strategy (CGIS) on students' attitudes towards Physics, and a significant difference in the post-attitude mean scores of students in the CGIS and the conventional teacher-centred instructional groups. Thus, cognitively guided instruction holds substantial promise as an effective pedagogical strategy for teaching Physics. In conclusion, this research underscores the importance of contextualizing instruction, as it actively engages students in the learning process and significantly enhances their attitudes towards the subject of Physics. The instructional structure which CGIS provides enables the validation of students’ knowledge-creation ability.

Published: November 2023

With the deepening of teacher educational reforms, increasing focus has been placed on the importance of evaluating student teachers’ teaching abilities in Chinese universities. The Delphi method and an Analytic Hierarchical Process were used to construct an evaluation system for student teachers’ teaching abilities. Delphi specialists included administrators, teachers and teacher educators working in primary, secondary and tertiary education. The evaluation items consisted of four dimensions, namely teacher ethics, teaching skills, educational ability, and developmental ability and a total of 31 indicators. Teaching skills were ranked highest, followed by teacher ethics, educational ability and developmental ability. The overall mean of the dimensions and components was rated as very important to important after three rounds of the Delphi process. Overall, the evaluation system demonstrated high reliability and validity; its’ entries were reasonably distributed indicating its evaluation potential and its’ weighting system denotes priorities for student teachers’ competencies’ evaluation.The evaluation system could help teachers identify key capacities in teacher training ,guide the development of talent nurturing programs, and provide developmental feedback for student teachers.

Performance como una práctica artística decolonizadora
Authors: Bock Gálvez Karin
Published: November 2023

En este texto se ensaya el planteamiento de cómo las acciones de performance pueden ser usadas para revitalizar las memorias de la violencia de género, invisibilizadas por efectos del poder patriarcal-colonial-moderno, y con ello, producir conocimiento decolonizador. Primero, se identifica la posición que ocupa el cuerpo de la mujer como lugar donde ocurre la violencia, convirtiendo a sus cuerpos en espectáculo de este fenómeno operando como pedagogías de crueldad. Como contrapartida a esta situación, se defiende la idea de que el cuerpo produce conocimientos que ponen en jaque este modelo y revitalizan el campo del saber. Mediante la activación del cuerpo como un lugar dotado de ontología y como herramienta ética, política, subversiva y salvaje se puede interpelar el lugar despolitizado en el que se ha ubicado a las mujeres. La performance puede transmitir otro comportamiento que van en un sentido contrario a la dominación.

Popüler Türk romanlarında aşk ve evlilik (1939-1945)
Authors: KARADOĞAN Sibel , ÖZDARICI Öznur
Published: November 2023

Türk romanı başlangıcından itibaren kadın, aşk ve evlilik konularını ele almıştır. Özellikle toplumsal hayatta kadının değişen yeri, aşk ve evliliğin seyrini değiştirmiştir. Aşk ve evlilikte kadın edilgen konumundan sıyrılarak seçici ve belirleyici olmuştur. Cumhuriyet Dönemi’nde yazılan popüler aşk romanlarının ana teması kadın erkek ilişkileri üzerine kurulmuştur. Bu romanlarda geleneksel evlilik modeli olan görücü usulü evliliklerin aksayan yönleri gösterilirken olması gerekenin aşk evliliği olduğu düşüncesi ele alınır. Romanlarda kahramanlar kuvvetle özlemini duydukları romantik bir aşk isteği içerisindedir. Bu isteklerine ulaştıklarında ise hayatın anlamı ve mutluluklarına ulaşmış olurlar. Dolayısıyla evlilikte idealize edilmiş fakat anlamı sorgulanmamış bir aşk tasarımı sunarlar. Kadın erkek ilişkilerindeki modernleşme isteğinin olumsuzluklarına da değinen yazarlar, özellikle evlilik dışı ilişkilerin bireysel ve toplumsal çıkmazlarına yer verirler. Kadın erkek ilişkilerinde flört normalleştirilerek muhafazakâr toplum yapısı kırılmaya çalışılmıştır. Bunun temel sebebi, modern yaşam tarzını oluşturma isteğidir. Ama yazarlar, evlilik olmadan yaşanan ilişkilerin özellikle kadının bağlılık duygusunu kaybetmesine, aile kurumunun çökmesine ve toplumsal yozlaşmaya sebep olduğunu göstermek ister. Bu sebeple aşkın evliliğe vesile olabilecek yegâne güç olduğu ve cinselliğin aşkın tamamlayıcı unsuru olarak evlilikte yaşanması gerektiği mesajını verirler. Bu çalışmada aşk ve evlilik konusu; Muazzez Tahsin Berkand, Mükerrem Kâmil Su, Peride Celal, Kerime Nadir, Esat Mahmut Karakurt, Oğuz Özdeş, Mahmut Yesari romanlarından hareketle örneklendirilmiştir.
Legal Policy to Handle Medicine Price in Indonesia: A Comparison Study With Other Countries
Authors: Zuardin Zuardin , Ratodi Muhamad
Published: November 2023

The use of medicinal right with an affordable price becomes a necessity for the public. The affordable medicine will reduce public health risks due to the public inability to buying common generic medication. An irrational difference in the medicine selling price at the consumer level was caused by a free price determined by pharmacy industries in the market mechanism.  The medicine selling price policies for pharmacies were only accommodated through the Minister of Health Decree Number 720/Menkes/SKIX/2006 which in fact can not provide a solution. Therefore, the government has to control the selling price in the market mechanism and to seek the strong legal force.
