Authors: Yuliani Febri
Published: March 2023

Forest fires are the most detrimental cause of forest destruction because in a short time, they can cause economic, ecological, aesthetic, and political losses. The purpose of this study is to analyze forms of biodiversity conservation carried out by local communities (ethnoecology) of people living in peat areas. This research was conducted in Riau Province, and the method used was qualitative. The unit of analysis in this study is the people who are considered to have knowledge about the implementation of inter-organizational networks in forest and land fire control in Riau Province. The results showed that forest and land fires that occurred in Riau Province were more common in company plantations and the rest occurred in community plantations. Implementation of inter-organizational networks in forest and land fire control in Riau province in the form of standards and objectives, resource policies, inter-organizational communication, and disposition (characteristics of implementing agencies). The recommendation from this research is to control forest and land fires in Riau Province starting from prevention and extinguishing to post-fire recovery, the local government massively socializing land clearing by burning to clear land without burning, as well as providing facilities and infrastructure for prevention, control, and repair after forest and land fires.

Published: March 2023

Migrant laborers from Indonesia have both beneficial and negative effects. This research aims to uncover the characteristics that impact family resilience among migrant workers from Indonesia. This form of research is qualitative and employs a literature review methodology. PMI family issues include a lifestyle of excessive consumption, family discord, parenting, and kid development. There is a shift in the family structure when a woman or husband becomes an Indonesian migrant worker. In this situation, the husband assumes the conventional tasks of the wife, such as childrearing and education; meanwhile, the woman is unable to fulfill the intangible rights and duties (inner life) of their marriage. This is a difficult situation for immigrant families. Intensifying long-distance contact between PMI and their families is the answer to their family troubles. This is to prevent putting the family at risk. Family functions are optimized to the greatest extent possible. In addition, participation and assistance from numerous stakeholders are required. Family watchdog institutions may give PMI family children financial literacy and parenting aid.

Examining the Indonesia Bureaucracy Response and Problem in Pandemic Times: A Preliminary Diagnostic Study
Authors: Faedlulloh Dodi , Karmilasari Vina , Utami Anisa , Fadoli M. Irsyad
Published: March 2023

This investigation was prompted by the conditions of the COVID-19 pandemic, which created very rapid changes in the bureaucratic environment. This initial study is intended to explain how the Indonesian bureaucracy responds to changes due to the pandemic. A literature study is used to aggregate some of the findings of the latest research in Indonesia and official and accountable reports on bureaucratic governance. General results show that the bureaucracy in Indonesia is still stuttering in carrying out its functions. When the public requires quick and fair service, bureaucratic formalism, as an effect of Weberian bureaucracy, finds its contradiction. Still, the response required by the public does not accompany it. Further studies must be initiated to formulate an agile and public-centered bureaucratic model in the post-pandemic era.

Published: March 2023

L'objectif de l'article est de présenter les résultats d'analyse sur la σ-convergence et la σ-divergence, ainsi qu'une analyse comparative multivariée de la liberté économique dans les 13 pays d'Amérique du Sud. Les pays concernés sont suivants : Argentine, Bolivie, Brésil, Chili, Colombie, Équateur, Guyane, Paraguay, Pérou, Suriname, Trinité-et-Tobago, Uruguay, Venezuela. Pour mener des analyses comparatives, les indices de liberté économique publiés par The Heritage Foundation à Washington et Wall Street Journal seront utilisés. Ils mesurent 12 aspects quantitatifs et qualitatifs regroupés autour des quatre piliers de la liberté économique : 1) état de droit - droits de propriété, efficacité judiciaire, intégrité gouvernementale ; 2) taille du gouvernement - dépenses publiques, fardeau fiscal, santé budgétaire ; 3) efficacité de la réglementation - liberté d'entreprise, liberté du travail, liberté monétaire ; 4) ouverture du marché - liberté commerciale, liberté d'investissement, liberté financière. Les données statistiques seront complétées par l'indice global de liberté économique pour chaque pays. Dans la recherche empirique, les mesures de σ-convergence et σ-divergence sont utilisées pour déterminer le degré d'homogénéité ou d'hétérogénéité des pays étudiés du point de vue de 12 zones et de la liberté économique moyenne à l'horizon temporal analysé. Le fait d'appliquer les méthodes sélectionnées d'analyse comparative multivariée, y compris l'analyse par grappes basée sur les méthodes hiérarchiques, représete le point culminant de la recherché empirique. L'analyse typologique est effectuée séparément pour 12 indicateurs partiels et l'indice global de liberté économique pour les 13 pays. Les matrices de similarité des pays, qui sont déterminées à cet effet, représentent les distances entre les séries temporelles des indices de liberté économique calculées sur la base de l'algorithme Dynamic Time Warping (DTW). Le programme R et les packages dtw et dtwclust sont utilisés pour l'analyse des clusters. Cet article est un complément important aux connaissances sur la création de la liberté économique dans les 13 pays Amérique du Sud dans les années 1996-2022.

L'objectif de cet article est d'analyser la coopération économique entre la Russie et l'Afrique qui, bien qu'ancienne, a connu des développements majeurs depuis les années 1990. Le mode de mise en œuvre de la présence russe sur le continent diffère à maints égards de celui des partenaires qualifiés de traditionnels à savoir la France, l'Europe, les USA et plus marginalement le Canada. L'examen documenté des principes de cette coopération, de ses caractéristiques, de ses principaux résultats et de ses perspectives permettent d'apporter une réponse à une question qui revient de manière récurrente dans les études, à savoir si la Russie est une menace ou une opportunité pour l'Afrique.
Énergie renouvelable, croissance économique et attenuation des émissions de dioxyde de carbone dans les pays de l'UEMOA
Authors: Baoula Kodjo W.
Published: March 2023

L'efficacité des énergies renouvelables pour assurer la croissance économique et la qualité de l'environnement devient un sujet important dans la littérature économique, étant donné que les énergies fossiles majoritairement utilisées et menacées par le risque d'épuisement entraînent une augmentation des émissions de gaz à effet de serre. L'objectif de ce papier est d'analyser l'effet de la consommation des énergies renouvelables sur la croissance économique et les émissions de dioxyde de carbone dans les pays de l'UEMOA. Pour ce faire, nous utilisons les fonctions de croissance et d'environnement avec une investigation empirique basée sur une régression linéaire en données de panel constituées des pays de l'UEMOA sur la période 1990 à 2015. Les résultats des estimations par la méthode de Pooled Mean Group développée par Pesaran et alii (1999) montrent principalement qu'à long terme, l'utilisation des énergies renouvelables contribue significativement à promouvoir la croissance économique et à atténuer la dégradation de l'environnement à travers la réduction des émissions de carbone. A cet effet, les décideurs politiques devraient orienter la politique énergétique de l'union vers un mix-énergétique dominé par la production et la consommation d'énergie renouvelable ; tout en mettant en place une politique de contrôle des émissions de CO2.
Étude empirique des « déficits jumeaux » pour le cas du Sénégal
Authors: Kebe Ndongo Mané
Published: March 2023

Cet article vise à vérifier l'hypothèse de neutralité ricardienne au Sénégal, à travers de l'existence ou non du phénomène des « déficits jumeaux ». L'objectif visé dans ce travail était d'étudier la corrélation entre le déficit budgétaire et le déficit du compte courant. La revue de la littérature théorique est axée sur les approches d'équivalence ricardienne et conventionnelle (classique et keynésienne) portant sur les effets de l'endettement public sur l'économie réelle. La revue de la littérature empirique a permis de revenir sur certaines applications par pays ou données de panel pour confirmer ou infirmer l'hypothèse de neutralité par une vérification de l'existence ou non du phénomène des déficits jumeaux. Ainsi, l'approche méthodologique adoptée est le test de cointégration des deux variables à travers l'utilisation du modèle à correction d'erreurs (MCE) suivant la méthode d'Engle et Granger (1987). Nos résultats indiquent une absence de cointégration entre les variables déficit budgétaire et solde du compte courant et donc de relation d'équilibre sur la période étudiée, entre ces deux variables, d'où une acceptation de la Proposition d'équivalence Ricardienne sur la période 1991-2020. Aussi, ce résultat s'identifie à la vérification de la Proposition d'Equivalence Ricardienne (PER) pour le Sénégal.

Waltheria indica is a common shrub found in many parts of Northern Nigeria for the management of several diseases. Although the ability of Waltheria indica to treat infertility, erectile dysfunction and impotency in male has been reported in ethno-medicine, there is no scientific study to verify its action on androgens and spermatogenic parameters. This study seeks to evaluate the effect of methanolic root extract of Waltheria indica on androgens and spermatogenesis in albino rats. Rats were grouped into four: 1, 2, 3 and 4 where 1(the control) received orally 1mL of normal saline. Groups 2, 3 and 4 received orally on daily basis, graded doses of 50, 100 and 200 mg/kg body weight of the plant extract, respectively, for 40 days. Administration of plant extract resulted in enhanced levels of testosterone, follicular stimulating hormone, luteinizing hormone, sperm count, sperm viability, and sperm mobility, testicular gamma glutamyl transferase, testicular alkaline phosphatase, testicular acid phosphatase and testicular cholesterol. The results show that methanolic root extract of Waltheria indica has demonstrated androgenic and spermatogenic activity which further substantiates its claimed traditional use in the management of infertility in male folk. Keywords: Waltheria indica root extract, infertility, erectile dysfunction, impotency in male, androgenic effect, spermatogenic effect

This study is to determine the antibacterial efficacy of Lawsonia inermis against methicillin-resistant Staphylococcus aureus (MRSA) which has become a leading cause of infections. The leaves of Lawsonia inermis also known as Henna or lalley leave were subjected to extraction with seventy percent (70%) methanol using the cold maceration technique after which phytochemical screening and partitioning were carried out following standard procedures, hence, three fractions of the methanol extract of Lawsonia inermis (crude extract, aqueous and chloroform fractions) were used against thirty strains of MRSA by using the agar well-diffusion and minimum inhibitory concentration as a determination method. Preliminary phytochemical screening revealed the presence of Alkaloids, Saponins, Tannins, Terpnoids, and steroids. A two old serial dilution was done for each of the fractions viz; 100mg/ml, 50mg/ml, 25mg/ml, 12.5mg/ml and 6.25mg/ml. The various dilutions were used on the test organism and there was increase in zones of inhibitions with increase in extract concentrations. At 100mg/ml, the crude fraction had a maximum inhibition zone of 15.30mm which was higher than the inhibition zone of the standard antibiotic used, and a minimum inhibition zone of 9 mm as compared to the standard antibiotic used having a minimum inhibition zone of 4.33mm. Among all the fractions used, the crude fraction of the methanol extract of Lawsonia inermis showed the best activity against the test organism (MRSA) Methicilin Resistant Staphylococcus aureus. Others showed lesser activity as compared to the standard antibiotic used. Keywords: Lawsonia inermis linn, MRSA, Crude extract

Many drugs are available to treat allergic condition. This review focused on why antihistaminics are best choice for treatment of allergic disorder especially allergic rhinitis (AR). AR is a chronic inflammatory disease. AR can be detected by its characteristics of nasal congestion, nasal itching, sneezing, rhinorrhoea, pruritis, redness, tearing and itching of eyes. This is very common and increases day after day. Allergic rhinitis is not lethal but interferes with daily schedule in a sustained manner. It is also observed that after COVID-19, stimuli reactions such as allergic condition, breathing difficulties and nasal irritation are quite common. It is very necessary to treat AR with an effective and powerful medicine because nowadays, many factors trigger these responses such as the environment, food products, pollution, etc. Before treatment of any symptoms it is very necessary to know it pathogenesis. Hence, in this review, we discuss the introduction of AR, its pathogenesis, diagnostics, classification and treatment. We also understand why levocetirizine, a third-generation antihistamine, is superior to all other antihistamines and the most favourable in paediatric patients in many ways. Keywords: Allergic rhinitis, Antihistaminic, Levocetirizine, COVID­19, Asthma, Nasal congestion

Published: March 2023

Al 2020 en Costa Rica únicamente, existen tres barreras dinámicas instaladas, dos de las cuales se encuentran en la Quebrada Burío. El cambio climático es un factor determinante ante el incremento de las intensidades de lluvia. Se espera un incremento del 20% para el año 2100 por lo que este dato se toma en cuenta para realizar todos los cálculos hidrológicos del caso de estudio. Al mismo tiempo, la implementación del modelo de Iber 2.5.1 es totalmente necesaria para la comprensión del comportamiento hidrodinámico de la quebrada y asimismo del comportamiento de los sedimentos en suspensión de ésta. Datos como hidrogramas, elevaciones obtenidas por medio de ortofotos de vuelos de aeronaves no tripuladas y concentración de sedimentos son los pilares para generar un modelo para este caso. La velocidad, altura del agua y comportamiento vectorial son los resultados obtenidos del modelo hidrodinámico generado por Iber 2.5.1. Así como el comportamiento de los sedimentos.

Los aldehídos en el ambiente se encuentran entre la mayoría de los compuestos orgánicos que participan en las reacciones fotoquímicas en la atmósfera, formando principalmente radicales en cantidades significativas. Además, presentan efectos nocivos sobre la salud de los habitantes de las ciudades con atmósferas contaminadas, principalmente compuestos como el formaldehído y el acetaldehído. En el presente trabajo se determinó, durante el 2017, la concentración de siete aldehídos en muestras de aire y agua de lluvia en un área de conservación de Costa Rica, llamada Reserva Biológica Los Cusingos, ubicada en el Pacífico Sur, Pérez Zeledón. Para el muestreo y el análisis de los aldehídos se utilizó el método TO-11A (EPA). El muestreo utilizó con cartuchos de adsorción recubiertos con una disolución de 2,4-dinitrofenilhidracina (2,4-DNFH). Las muestras fueron cuantificadas por medio de un cromatógrafo líquido acoplado a un detector UV-Visible. Las mayores concentraciones de aldehídos en las muestras de aire corresponden a formaldehído (62.2 ± 3.1 μg/m3), acetaldehído (88.1 ± 4.9 μg/m3) y acroleína (102.2 ± 5.2 μg/m3) en un periodo de 4 horas. Se determinó que el heptanal fue el aldehído menos contribuyente a la cantidad de aldehídos totales, al encontrarse por debajo del límite de detección (< LC = 0.015 mg/L). Para las muestras de agua de lluvia, el único aldehído cuantificado fue el formaldehído cuya concentración osciló entre (0.00439 ± 0.0062 a 0.08 ± 0.13) mg/L. Los resultados obtenidos en la muestra de aire sugieren un aumento en la concentración de aldehídos correlacionados con la radiación solar y con la temperatura, sugiriendo como principal contribuyente las reacciones fotoquímicas que se llevan a cabo en el aire con hidrocarburos precursores para la generación de contaminantes secundarios.

Published: March 2023

Alrededor del año 2007 las Naciones Unidas indicaban preocupación por los residuos sólidos que estaban llegando al mar producto de las actividades en las zonas terrestres, así como propiamente las generadas en el mar, amenazando la salud de los océanos, la seguridad y calidad de los alimentos, la salud humana, el turismo costero y la fuente de trabajo de muchos pescadores, cuyo sustento depende del mar. Costa Rica cuenta con dos costas, una en el Océano Pacífico y otra en el mar Caribe, con abundantes recursos naturales tanto en los ecosistemas marinos como en los terrestres. Pero estos, se encuentran severamente amenazados debido al abuso que se ha dado a los recursos y a las actividades antropogénicas. Por lo anterior y sumándose al interés global de proteger los océanos, el gobierno de Costa Rica realiza el Plan Nacional de Residuos Marinos de manera participativa e intersectorial. Para ello se efectúa un análisis de línea base con información recolectada de literatura internacional y nacional, con talleres participativos donde se presenta la información de la situación actual de la gestión de residuos, con visitas a asociaciones de pescadores en el Pacífico y en el Caribe, entrevistas, cuestionarios y discusión de los temas relevantes para el país. El resultado de la recolección de la información es lo que se presenta en este artículo. En él se resume el aporte de las fuentes terrestres y marinas, el impacto a los ecosistemas, el monitoreo que se realiza, los distintos programas de educación sensibilización e información con que se cuenta, la normativa internacional y nacional, terminando con un análisis de las actividades de investigación, desarrollo y los retos para la innovación. Se presentan además conclusiones sobre el estado actual de la gestión de residuos marinos en los distintos ámbitos analizados.

Published: March 2023

Los biomateriales se han constituido como una herramienta fundamental en la ingeniería de tejidos y la medicina regenerativa, debido a que tratan y en algunos casos logran mimetizar el tejido original. Actualmente se estudian los cementos óseos como biomateriales sustitutos de hueso en diferentes patologías, y se analizan diferentes compuestos con contenido de hidroxiapatita para dotarlos de bioactividad. En el presente estudio se tuvo como objetivo evaluar el carácter bioactivo en muestras de hidroxiapatita obtenida a partir de cáscara de huevo para usarse como posible adición a los cementos óseos. La síntesis de la hidroxiapatita se realizó por el método de precipitación, en la que se usó el óxido de calcio proveniente de las cáscaras de huevo y el ácido fosfórico como fuentes de calcio y fósforo, respectivamente. La caracterización química realizada por medio de espectroscopia Raman y EDS, permitió evidenciar que se logró obtener hidroxiapatita a partir de éste residuo con una relación Ca/P de 2,187. Para el estudio de bioactividad, se sumergieron las muestras en polvo en un fluido biológico simulado durante 14 y 28 días, y con espectroscopia Raman y microscopía SEM-EDS, se caracterizaron las muestras tanto antes como después del tratamiento para determinar su relación Ca/P y comportamiento con el tiempo. Las técnicas de caracterización permitieron determinar que la hidroxiapatita de cáscara de huevo presenta propiedades bioactivas y que además es un material estable al estar en contacto con el fluido biológico simulado, una gran candidata para usarse como adición a los cementos óseos convencionales.

Fermentación en estado sólido como método para reducir factores antinutricionales en la harina de frutos de Artocarpus altilis
Authors: Brea Maure Odelín , Borrás Sandoval Luis Miguel , Rache Cardenal Leidy Yanira
Published: March 2023

Con la fermentación en estado sólido se convierten sustancias orgánicas complejas en simples por la acción de enzimas microbianas y se modifican las características físico químicas del alimento conllevando a una mejora en la biodisponibilidad y calidad de los nutrientes cuando se utilizan diferentes especies vegetales como alimento animal. Los metabolitos secundarios producidos por las plantas pueden afectar la salud de los animales cuando las consumen. Eliminar o disminuir la cantidad de los compuestos dañinos, además de mejorar el valor nutritivo es una prioridad. En el presente trabajo se evalúa la fermentación en estado sólido con algunas modificaciones como opción para eliminar o disminuir el contenido de taninos y saponinas presentes en la harina del fruto de Artocarpus altilis (árbol del pan). Se analiza el efecto del tiempo de fermentación, la adición de urea, vitafer y carbonato de calcio a distintas concentraciones. Los resultados del tamizaje fitoquímico y la cuantificación de taninos y saponinas en las diferentes variaciones de la fermentación, muestran que adicionando Vitafer (5%) y carbonato de calcio (0.6%) disminuye la concentración de taninos y saponinas en la harina del fruto de Artocarpus altilis.

Published: March 2023

Central serous chorioretinopathy (CSCR) is one of several retinal disorders that may cause visual loss. It is characterized by serous detachment of the neurosensory retina, often associated with focal detachments of an altered retinal pigment epithelium, mostly confined to the macular area. As CSCR is considered to be correlated with an increased level of testosterone, it was of the interest if it is also linked to the occurrence of polycystic ovary syndrome (PCOS).

Crisis Ordinary, Lauren Berlant, and Counter-Politics
Authors:   The Criticism and Theory Society of Korea, Yoon Joewon
Published: March 2023

Optimism is cruel when it promises and yet does not deliver happiness. In the postwar proliferation of neoliberal economic order, the sense of crisis saturates everyday life and the bourgeois promise of a ‘good life’ is no longer attainable. Nevertheless, the fantasy of a ‘good life’ binds the subject to the life that exhausts him/her. The subject does not relinquish the attachment to that fantasy, for the sense of proximity engendered through that attachment serves to form a significant affective foundation for some form of sustainable everyday life. Such is the double bind of cruel optimism, which Lauren Berlant explores in her Cruel Optimism (2011). This essay explicates key notions and thoughts Lauren Berlant extends in Cruel Optimism and a few other works, and attempts to read some aspects of contemporary Korean society through Berlant’s thoughts as an hermeneutic tool. While critically testing and assessing Berlant’s work, this essay also turns to her multi-faceted understanding of “lateral agency” as a possible path for reinventing subjectivity and renegotiating citizenship. Ultimately, I suggest literature as a minoritarian site where a collective cultivation of lateral agency can take place for an affective counter-politics against the ongoing crisis and the double bind of cruel optimism.

Giorgio Agamben’s ideas of sovereign power and ‘Homo Sacer’ received a lot of criticism because the decline of nation-states due to globalization tends to be equated with the weakening of sovereignty. Especially, Judith Butler argues that the process of removing the heterogeneity within the citizens to invent those who are the foundation of the nation-state cannot be explained by the operation of sovereign power and the mass production of ‘bare lives’ presented by Agamben. Butler explains the ‘statelessness’ in the sense that the situation of global violence is out of territorial conditions, and also highlights the ‘statelessness’ to deconstruct the basis of the nation-state and explore the possibility of resisting it. According to her, given the diaspora produced across territories and the operation of power, this violent exclusion today is caused by neoliberal governmentality, not sovereign power. And it is necessary to see power working in many ways to materialize the diaspora and resist state violence. For Butler, the concept of diaspora is presented as a resistance practice and ethical request of the dispossessed. However, this thesis aims to reveal that Butler’s criticism against ‘bare life’ is misread. Butler’s misinterpretation arises from the difference in perspective of Agamben, who reads Michel Foucault and Hannah Arendt. If sovereignty is an anachronism to Butler, the original form of sovereignty is biopolitics to Agamben. In addition, Butler considers Arendt distinguishing between the public and private realms and maintaining a discriminatory perspective on the private, whereas Agamben reads that Arendt paid attention to the modern reality in which this public/private distinction is collapsing. Unlike Butler’s criticism, ‘bare life’ does not exist outside of the polity or power. Even if the citizen belong to the nation state, there is the potential for them to become a “bare life,” or diaspora at any time, which reveals the possibility of rethinking the identity of the diaspora.
Hate Speech, Subject Agency and Performativity of Bodies
Authors:   The Criticism and Theory Society of Korea, Jeong Haeook

Hate speech is any form of expression that vilifies and discriminates against individuals or groups based on their identity, including race, ethnicity, national origin, gender, sexual orientation, religion, and more. However, hate speech is not merely an emotional expression; it can often be intertwined with fake news and logical reasoning that appears convincing. This article explores Judith Butler's theories on hate speech, how she resists it, and how to draw a good life out of a bad life. Firstly, it examines the limitations of the traditional dichotomy between reason and emotion and how it relates to issues such as hate speech, fake news, and post-truth. Secondly, it analyzes hate speech as either an illocutionary or perlocutionary speech act, and reviews legal cases related to hate speech in the USA through Judith Butler's Excitable Speech(1997). Thirdly, it explores Butler's analysis of Freud's work in The Force Of Nonviolence(2020), including his ideas about the importance of emotional ties and communities of feeling, and how he aimed to overcome blind fury in his later years. The article also discusses how Butler supplements Freud's unfinished research and extends his ideas beyond their original limits. Finally, the implications of these attempts for Korean society, which is currently grappling with the problem of hate speech, are examined in the last section.
World Literature and the Problem of Modernity
Authors:   The Criticism and Theory Society of Korea, Kim Yong Gyu

This paper aims to critically examine the problem of modernity in world literature and, more specifically, in the theory of world literature by Frederic Jameson, Neil Lazarus, and Nicholas Brown, who have formulated a new concept of modernity against Western modernity. For a long time, world literature has been regarded as a field in which the ideas and values of Western modernity were embodied. This led to the negative labeling of non-Western literature as less worldly and more local literature that falsely imitates the modernity of Western literature. So the problem of modernity, such as how to overcome Western modernity and rethink the concept of modernity radically, has become one of the essential issues in the recent theories of world literature because we can not achieve the further development of world literature without properly criticizing the existing concept of Western modernity. What is interesting in Jameson’s idea of singular modernity and Lazarus and Brown’s theory of world literature is that they criticizes the Western conception for modernity and suggests the new concept of modernity that pays attention to the proper problems of capitalism rather than the West. Moreover, their theory pursues for a new political reading on the modernity and universality of literature, overcoming the dichotomy between central and peripheral, western and non-western. Their theory of world literature has also significant implications for us who have been strongly influenced by Western modernity. It makes us realize that our own literature can be world literature when we thoroughly explore our own modernity and the problems of capitalism. It also recalls us the basic fact that world literature is a literature that can search for political possibilities in the modernity of our own world and its internal contradictions and cracks.

The remains of the middle Neolithic age in the central east coast area had no clear results other than those of Jigyeong-ri, Yangyang. With the excavation of Chodang-dong site, a detailed review of the middle Neolithic age became possible. In Chodang-dong Neolithic site, comb-patterned pottery, stone tools, dwellings, and Open-Air Hearths were investigated.
The study of the Neolithic age in the central east coast area focused on the chronology and the background of the establishment of the Middle Age culture through comb-patterned pottery. The middle Neolithic age of the central east coast area was established under the influence of comb-patterned pottery in the Midwest area. Later, it was thought that comb-patterned pottery, which had the traditional of the southern area was excavated.
The analysis was focused on the relics excavated from the Neolithic site in Chodang-dong. As a result, the lip pattern of the comb-patterned pottery is divided into a single thread and a zip line pattern. Most of the Neolithic site in Chodang-dong are the latter. Some of the site of Gangneung are the former. Comb-patterned pottery engraved with short horizontal and slanted gates have been excavated from the remains of Open-Air Hearths. The Open-Air Hearths of Chodangdong site was intensively used in the late Neolithic age rather than the middle.
Chodang-dong Neolithic site was a large village with many dwellings and Open-Air Hearths in the middle of the Neolithic Age. In the middle Neolithic age, Chodang-dong site were the residential area south of Gyeongpo Lake. Afterwards, in the late Neolithic age, an Open-Air Hearths was installed throughout the first sand dune area. However, he lived in Chodang-dong site and did not use Open-Air Hearths.

The Geumryeong-tomp is a tomb in the Silla period, located at the northern end of Gyeongju. It was first excavated in 1924 and again in 2018. Now in 2022, a special exhibition of past archaeological achievements and research is being held. In this tomb, which was named as a ‘Geumryeong-tomb’ in commemoration of the excavation of golden bell, precious Silla precious metal ornaments such as golden crown and golden belt were also excavated. The Geumryeong-tomb was recognized as the tomb of Prince Shilla. It was because the golden crown and the golden belt were all small items suitable for young people of small size.
In this article, I have illuminated the objects and the people who handled them with the material of the Geumryeong-tomb. With the results of the research accumulated until recently, I looked at the Geumryeong-tomb ornaments. Explain the speciality and production technique of the Geumryeong-tomb.
Because ornaments are artifacts, people are involved in some way. In this article, I explored the three subjects involved in the use of ornaments: the dead, the funeral, and the craftsmen.
Find out why the Geumryeong-tomb’s dead man is an infant. I looked at the funeral director who is the actual leader of this funeral. The funeral ornaments prepared by the funeral organizer were derived and explained his presence. Finally, I looked at the craftsmen who made the funeral items. The main characters on the stage of death and funeral are the dead, the funeral, and the craftsmen. And they are intertwined with relics.
The purpose of this study is to explore their correlation and Silla society with the theme of Geumryeong-tomb ornaments. This study explains the archaeological existence of Geumryeong-tomb’s dead man, funeral director, and craftsmen with clues to ornaments.
Hierarchies and Characteristics of the Graveyard-typed Tombs in the Goryeo Dynasty: Centered on South Korea Regions
Authors:   Central Institute of Cultural Heritage, Lee Won-Jeong
Published: March 2023

In this study, tombs with graveyard facilities were classified into graveyard-typed tombs and divided into three stages to understand their changes. In the 1st step before the 12th century, graveyard-typed tombs which had been constructed around Gaegyeong gradually spread to Yanggwang-do, south of Gyeonggi, with small sized graveyard-typed tombs only. In the 2nd step, from the 13th to the middle of the 14th century, tombs began to be built throughout South Korea in earnest and medium sized graveyard-typed tombs appeared. In the 3rd step of the late Goryeo Dynasty to the early Joseon Dynasty. ranging from the late 14th century to the middle of the 15th century, the number of the graveyard-typed tombs recorded the highest and it is possible to see the large sized tombs.
The hierarchies in the graveyard-typed tombs were classified based on the similarities in the tombs for royals and officials. The type Ⅰd2·Ⅰe2·Ⅱb2 may be referred to as the higher and the type Ⅱb1·Ⅱc1·Ⅱd1 as the lower types.
It is assumed that the buried of the graveyard-typed tombs after the 12th century were those of the upper middle class that could use the compulsory labor. In particular, tombs of the higher hierarchy are regarded to be the ones for the gentry(Sajok) who came from the central government and moved to certain region. Accordingly, formative diversity in the higher hierarchy can be interpreted to be resulted from differences in rank of the gentry and hierarchy of their families. Furthermore, the status of the local officials(Hyangri) began to be lowered after the 12th century and the graveyard-typed tombs for the lower hierarchy may be constructed under the influence of the tombs for the officials.
On the other hand, graveyard-typed tombs tended to be located mainly at a big town along the traffic networks such as Yeok-ro and Joun-Ro. Besides, relics from the island areas of Yanggwang-do show that graveyard-typed tombs had the different forms according to construction groups. The study reveals that at Jeolla-Do and Gyeongsang-Do there was a difference in the number of the graveyard-typed tombs due to the influence of Eight Injunctions by Taejo, exploitation of Jeolla-Do and the growth of the emerging gentry at Gyeongsang-Do. Besides. at Tamla there were more higher types than in land under the influence of Yuan. At Gyoju-Do and Donggye, it is not possible to see the graveyard-typed tombs since rough terrains prevented local officials from growing up.
