Authors: Suwanda A.K Patra
Published: March 2024

Sebagai salah satu alat komunikasi, fotografi senantiasa berperan menjadi media pendokumentasi dalam momen tertentu yang berfungsi sebagai  penyampai pesan dan memiliki muatan estetis. Sebagai medium yang dapat merekam gambar dan momen peristiwa ataupun fenomena kehidupan, fotografi dapat menangkap dan menjadikannya catatan bentuk visual yang abadi. Dalam tulisan ini, materi yang akan dibahas bertema tentang seni pertunjukan, atau lebih spesifiknya lagi karya fotografi pertunjukan seni tari. Herfan Rusando,  Fotografer yang telah berkimpung selama puluhan tahun di dunia seni pertunjukan di Institut Seni Budaya Indonesia (ISBI) Bandung telah memunculkan beberapa karya seni fotografi yang menarik untuk dikaji dan dianalisis. Setidaknya ada 3 (tiga) buah karya fotogarfi yang akan ditelaah, yaitu : Tari Sulintang, Tari Padusari, dan Dramatari Somantri – Sokrasna. Metode untuk mengkaji ketiga karya tersebut yakni : Teori Estetika dan Metode Kualitatif Analisis Fotografi. Dipilihnya karya fotografi seni tari ini merupakan tantangan tersendiri, mengingat masih langkanya tulisan yang memuat tema fotografi seni pertunjukan. Diharapkan dengan munculnya tulisan ini ke permukaan ada pihak-pihak yang menyadari bahwa seni tari tradisi Sunda sebagai produk budaya bisa diapresiasi oleh berbagai kalangan dengan latar belakang yang berbeda.

THE ICE SILK ROAD OR MIDGARDSORM: POSSIBLE RECENT CHALLENGES FOR CHINA’S ‘ONE BELT, ONE ROAD’ PROJECT THROUGH THE NORTHERN ARTIC ROUTE
Authors: Kozarski Michael
Published: March 2024

China’s global project ‘One Belt, One Road’ has been one of the most frequently covered subject by scholars in recent human history. However, there is one more aspect which remains hidden in this topic – The Polar Maritime Route. It is the third and for now final aspect in the new geopolitical perception of contemporary Chinese thought, and is often referred to as the Ice Silk Road or in this case, Midgardsorm. Scholars and analysts often focus either on the Silk Road Economic Belt or on the 21st-Century Maritime Road and leave the Ice Silk Road in the margins. The main task of the author is to find, if possible, any future outside challenges which may obstruct the pavement of the Ice Silk Road through the Bering Strait and prevent the connection between China and Western-Central Europe via the North Maritime Route or the Artic Maritime Route.

“THE CELESTIAL” AND “THE RUSSIAN WORLD” – PAST, PRESENT AND PERSPECTIVES
Authors: Stefanov Nako
Published: March 2024

The development of relations and interactions between historical China (the Celestial, today People’s Republic of China /PRC/) and historical Russia (the Russian world, today Russian Federation /RF/) largely determines the course of political and economic processes not only in Eurasia, but – especially today – also at the global level. The goal of the proposed research is to review the Sino-Russian relations in the past and the present and predict their likely future. This goal is achieved with the tasks presented in the main sections of the work: 1. The historical legacy in the relationships and interactions of the “Celestial” with the “Russian World” – about the ups and downs in the dynamics of the past; 2. The modern world – factors and circumstances determining the positives and negatives in the Euro-Asian China-Russia part of the US-China-Russia global equation; 3. Instead of a conclusion: About the prospects of Chinese-Russian relations and interactions – optimistic, balanced, and pessimistic scenarios. The main thesis of the paper is that, despite the sometimes more-than-ambiguous historical past, today’s positive trends in the development of the relations between the PRC and the Russian Federation, which are determined by objective circumstances, create a higher probability in a shorter or longer-term perspective for an optimistic or at least balanced development scenario rather than a pessimistic one.

ABOUT CHINA’S 14th FIVE-YEAR PLAN AND HARMONY
Authors: Mandova Iskra
Published: March 2024

We know that China has been adopting Five-year plans since 1953; they are a system of planned initiatives that the country seeks to pursue in its future socio-economic development. The Fourteenth Five-Year Plan (FYP) of China (2021– 2025), approved in March 2021, is the main topic of this article not only because of the important strategic and geopolitical place of China in the modern world, but also because of the need for such publications in our country. We can read that this five-year plan sets key milestones for China, but also for every other country in the world: tackling poverty, trade expansion, investment in science and technology, environment protection, etc. The aim here is to consider not only the economic and social aspect of the planned development, but also to look for the roots of modern Chinese politics in traditional culture and ancient Chinese philosophy. In today’s global world, it is not possible for any nation or culture to exist in isolation and develop on its own. That is why Chinese people say that China needs the world, but the world also needs China, especially the modern world.
ЕNERGY PRACTICES IN THE CHINESE ARTS OF WAR AND PEACE
Authors: Ivanov Valeri
Published: March 2024

The Chinese cultural tradition connects the origin and existence of the world, the human being and society with the presence of a unified and all-pervading energy substance. This substance creates both the formal structures and their comparability and interrelationship. This universal substance is shared on all levels and aspects of existence, regardless of their manifestation. In this mutual sharing, the substance undergoes its fluctuations and transformations which are expressed in constructive or destructive ways of stimulating or repressing influence. This substance can be perceived, studied, understood, guided, and used, consciously or not. This view delineates the unified cosmos in which the subjective and the objective are only a matter of reference in determining existence.

Abandonar, transformar, recordar: dues mirades a les ruïnes contemporànies
Authors: Clot-Garrell Anna
Published: March 2024

La present ressenya posa en relació la lectura dos llibres sobre els paisatges de l’abandó contemporanis, on diferents tipus ruïnes proliferen, resten i s’acumulen. D’una banda, el llibre de Cal Flyn Islas del Abandono. La vida en los paisajes posthumanos (2022) i, d’una altra, el llibre de Jaume Corominas Fígols les Mines. Esplendor i decadència d’una colònia minera (2019). Flyn i Corominas furguen des de diferents geografies, mirades i escriptures les presències i absències que configuren aquests paisatges, que a voltes ens atreuen i a voltes ens desolen. Ambdós autors ens conviden a través dels seus treballs a mirar de cara aquestes indrets i les seves ruïnes en comptes de girar-nos-hi d’esquena, per copsar com creació i destrucció esdevenen un binomi difícil de destriar.
Abiy Ahmed's Domestic Policy in Ethiopia: Securitization and conflict resolution
Authors: Belkov Aleksandr Dmitrievich
Published: March 2024

The subject of this study is a set of political reforms carried out by Ethiopian Prime Minister Abiy Ahmed from 2018 to the present. The object of the study is the internal political contradictions accumulated in Ethiopia from 1974 to 2018. The purpose of the work is to test the hypothesis that the policy of A. Ahmed is subject to the provisions of the theory of securitization of B. Buzan and O. Weaver and is aimed at transforming the conflict education of Ethiopia into a security regime. The topic of the study is relevant, since Ethiopia is considered by a number of scientists as a potential regional heavyweight capable of stabilizing the Horn of Africa region and ultimately influencing the security of the whole of Africa. Therefore, it is important to study the dynamics of political processes in modern Ethiopia. The research is based on the theory of regional security complexes by B. Buzan and O. Weaver. The methods of work are qualitative content analysis of official documents and expert opinions, as well as event analysis, logical and philosophical assumptions are allowed. A realistic approach is used to analyze the internal political situation in Ethiopia. The scientific novelty of the work lies in the fact that the policy of Abiy Ahmed is analyzed not from the standpoint of historical approaches, but from the point of view of political science theory, which is applied to the political process taking place in our time. The author concludes that the political course of A. Ahmed is determined by the difficult situation in which Ethiopia found itself by 2018. The Prime Minister is trying to stabilize the situation in the country, using his rich experience and professional knowledge, trying to change Ethiopia's position as a conflict entity to a security regime, his internal policy traces approaches based on strengthening the central government, which, from the point of view of the theory of B. Buzan and O. Weaver, makes Ethiopia a functional entity capable of respond to existential threats and develop successfully.

Authors: Castillo-Navarrete Juan-Luis , Bustos Claudio , Guzman-Castillo Alejandra , Zavala Walter
Published: March 2024

In a competitive and demanding world, academic stress is of increasing concern to students. This systemic, adaptive, and psychological process is composed of stressful stimuli, imbalance symptoms, and coping strategies. The SISCO-II Academic Stress Inventory (SISCO-II-AS) is a psychometric instrument validated in Chile. It evaluates stressors, symptoms, and coping, both individually and globally. For its practical interpretation, a scale is required. Therefore, this study aims to descriptively analyze the SISCO-II-AS and to obtain its corresponding scales. Employing a non-experimental quantitative approach, we administered the SISCO-II-AS to 1,049 second and third-year students from three Chilean universities, with a disproportionate gender representation of 75.21% female to 24.79% male participants. Through descriptive and bivariate analysis, we established norms based on percentiles. For the complete instrument and its subscales, significant differences by sex were identified, with magnitudes varying from small to moderate. For the full instrument and its subscales, bar scale norms by percentile and sex are presented. Each subscale (stressors, physical and psychological reactions, social behavioural reactions, total reaction, and coping) has score ranges defined for low, medium, and high levels. These ranges vary according to the sex of the respondent, with notable differences in stressors and physical, psychological, and social behavioural reactions. This study stands out for its broad and heterogeneous sample, which enriches the representativeness of the data. It offers a comprehensive view of academic stress in college students, identifying distinctive factors and highlighting the importance of gender-sensitive approaches. Its findings contribute to understanding and guide future interventions. By offering a descriptive analysis of the SISCO-II-AS inventory and establishing bar norms, this research aids health professionals and educators in better assessing and addressing academic stress in the student population.
Los ríos temporales en la península ibérica: notas históricas y alguna reflexión
Authors: Prat Narcís
Published: March 2024

El autor hace un repaso a los inicios de los estudios de los ríos temporales (o intermitentes) en España en el siglo XX partiendo de las primeras contribuciones de Margalef y llegando hasta los inicios del siglo XXI. Los estudios se iniciaron en los años setenta especialmente en el arco mediterráneo y en los Departamentos de Ecología que en aquel momento empezaban a trabajar en el tema como en Murcia (ríos semiáridos o ramblas) o en Barcelona y Granada (ríos mediterráneos). Se destacan los cursos organizados por Margalef en el IAMZ (Instituto Agronómico Mediterráneo de Zaragoza) y la importancia que tuvieron en la formación de limnólogos en España, así como que fueron un vehículo de contacto de los investigadores españoles con los primeros espadas de la Limnología en aquellos años. Los libros de Margalef de 1983 y el que editó derivado de los cursos del IAMZ (1994), ofrecen un buen panorama de la limnología en España donde los ríos no tienen un papel destacado ni tampoco los temporales. El nacimiento de la Asociación Española de Limnología y sus congresos fueron un buen caldo de cultivo para los estudios de Limnología en España y de ríos en particular. En las Actas de sus congresos primero, y en la revista Limnetica después, se publicaron los primeros trabajos sobre ríos temporales. El proyecto Guadalmed y algunos trabajos de síntesis entre final de los años noventa y principios de los dos mil marcan el final de esta fase “histórica”. También se examinan la importancia de estos estudios para la gestión del agua y su relación con la DMA (Directiva Marco del Agua) y se destaca la colaboración entre la Administración y los ecólogos en la producción de protocolos que han sido muy útiles para el conocimiento de los ríos temporales y su inclusión en los tipos de ríos a gestionar en el contexto de la DMA.

Authors: Benson G. A. S. , Oyetunde O. A. , Joda A. O. , Nofiu A. O. , Balogun K. L.
Published: March 2024

Sitophilus zeamais is perhaps the most important storage insect pest of maize. The negative health implication of synthetic pesticides necessitates research into botanicals. We investigated the efficacy of ground Piper guineense (particles sizes 150, 300, 600, 1180, and 2360 µm) in controlling S. zeamais. The botanicals were compared with pirimorphos methyl and control (untreated seeds). Completely Randomized Design was used with three replications. Each treatment was infested with 20 adult weevils. Weevils were withdrawn after 14 days and the experiment was observed for another 38 days to count emerged adult weevils, numbers of damaged grains and exit holes on seeds, and determine loss in seed weight. Progressive efficacy and significant differences were observed among the botanicals and Pirimorphos methyl from four days after treatment application (DAT) to 14 DAT (90%, 100%, 100%, and 46.67%for Pirimorphos methyl, 150, 300, and 2360 µm of Piper respectively) as the particle size decreases. Piper of 150 and 300 µm particle sizes produced no new adult weevil and no seed weight loss at 52 DAW compared to others. The efficacy of piper at different particle sizes from 4 DAT showed that graduating piper particle size has significant effects on its insecticidal activity. It was concluded that ground piper of particle size 150µm is the most effective and is therefore recommended for effective control of maize weevils in storage.

The strategy is based on the nondestructive (noncovalent) functionalization of pristine CNTs and the subsequent in situ synthesis of a variety of different nanoparticles, including metal, semiconductor, and insulator particles, on the modified CNTs. This strategy has been demonstrated here with Pt, CdS, and silica nanoparticles. It is believe that this technique will provide a simple and convenient route to efficiently assemble a wide variety of nanoscale particles/clusters on the surfaces of CNTs, and will enable the construction of nanoscale heterostructures with novel functionalities in nanotechnology.
Predicting food safety losses in turkey processing and the economic incentives of hazard analysis and critical control point (HACCP) intervention

Turkey is an important food commodity whose total value of U.S. production amounted to $2.72 billion in 2003. Empirical evidence suggests that among broilers, eggs, turkeys, and chickens, Salmonella contamination of ground turkey is highest at 49.9% prior to hazard analysis and critical control point (HACCP) implementation and 26.6% after HACCP implementation. Salmonella and other microbial outbreaks have greatly contributed to the large number of food recalls in the meat and poultry industry; therefore, processed turkey constitutes a prime commodity for HACCP intervention analysis. Value‐at‐risk provides a framework for assisting firm management to assess food safety risks in monetary terms, and to evaluate the economic incentives of control measures like HACCP. Results show that food safety losses as measured by downside risk significantly declined following HACCP implementation. Medium‐ and large‐scale turkey processors are more likely to derive more benefit from implementing an augmented HACCP plan than a generic HACCP plan.

Intrahepatic cholangiojejunostomy following hepatobiliary resection
Authors: Nagino M , Nishio H , Ebata T , Yokoyama Y , Igami T , Nimura Y
Published: October 2006

Background

Although intrahepatic cholangiojejunostomy is technically difficult, with recent improvements in surgery it should be possible to perform the anastomosis safely. The aim of this study was to evaluate the incidence of anastomotic leak after intrahepatic cholangiojejunostomy and to identify risk factors for such leakage.

Methods

Intrahepatic cholangiojejunostomy was performed in 423 patients undergoing hepatobiliary resection between January 1991 and December 2005. Anastomotic leak was proven radiographically by leakage from the anastomosis of contrast medium introduced via a biliary drainage tube placed during surgery.

Results

Anastomotic leak occurred in 27 patients (6·4 per cent), and was not related to the number of bile ducts reconstructed. The leak rate decreased significantly from 9·5 per cent (19 of 199) in the first 10 years to 3·6 per cent (eight of 224) in the last 5 years. Anastomotic leak was often followed by infections such as wound infection, intra-abdominal abscess and bacteraemia. Multivariable analysis identified age and intraoperative blood loss as independent risk factors for anastomotic leak. All leaks were treated by maintaining a prophylactically placed drain near the cholangiojejunostomy; neither repeat laparotomy nor percutaneous transhepatic biliary drainage was required.

Conclusion

Although demanding, intrahepatic cholangiojejunostomy can be performed successfully with a relatively low failure rate. Routine use of prophylactic drains and anastomotic stenting allows safe management of anastomotic leak with conservative therapy.
Laparoscopic gastrectomy with regional lymph node dissection for upper gastric cancer
Authors: Tanimura S , Higashino M , Fukunaga Y , Kishida S , Ogata A , Fujiwara Y , Osugi H
Published: October 2006

Background

The technique and results of laparoscopic gastrectomy in 110 patients with gastric cancer located in the upper third of the stomach are presented.

Methods

Proximal gastrectomy was performed for lesions in the upper third of the stomach, and total gastrectomy for those that spread over both the upper and middle third. D1 and D2 lymph node dissection was undertaken in patients with T1 or T2 lesions. Anastomosis of the oesophagus was performed intracorporeally using a conventional circular stapling device or a laparoscopic linear stapler.

Results

Median operating time was 247 min for proximal gastrectomy and 285 min for total gastrectomy; median blood loss was 207 and 334 ml respectively. A median of 23 lymph nodes was harvested from patients in the proximal gastrectomy group and 34 from those having a total gastrectomy. There was minimal morbidity and fast recovery after surgery. Postoperative recurrence occurred in only one patient, giving a recurrence rate of 0·9 per cent.

Conclusion

Laparoscopic gastrectomy for upper gastric cancer appears to be a safe and curative procedure.
Detection of postoperative pancreatitis after pancreatic surgery by urine trypsinogen strip test
Authors: Räty S , Sand J , Nordback I
Published: October 2006

Background

The urine trypsinogen strip test has been used successfully in the diagnosis of pancreatitis of various aetiologies, but has not been studied in postoperative pancreatitis. The aim of this study was to evaluate this test for the diagnosis of postoperative pancreatitis after pancreatic resection.

Methods

Fifty patients undergoing pancreatic resection were included. The urine trypsinogen strip test was done daily during the first postoperative week, blood was analysed before and 4, 6 and 10 days after surgery, and amylase activity in the drainage fluid was measured on days 4 and 6. Patients underwent computed tomography (CT) before operation and on days 2 and 6 afterwards.

Results

Thirteen patients (26 per cent) developed CT-detected pancreatitis after operation. In 12 of these patients pancreatitis was detected on the second postoperative day. The urine trypsinogen test was positive in all 13 patients with postoperative pancreatitis, and was already positive on the first day after surgery in 12. The sensitivity, specificity, and positive and negative predictive values of the trypsinogen strip test in detection of postoperative pancreatitis were 100, 92, 81 and 100 per cent respectively. In receiver–operator characteristic analysis the area under the curve (AUC) was higher for the urine trypsinogen strip test (AUC 0·959) than for a serum amylase level more than two (AUC 0·731) or three times (AUC 0·654) above the upper normal range in the diagnosis of postoperative pancreatitis. Patients whose recovery was complicated by pancreatic fistula, detected by drain output measurements on day 6, more often had a positive urine trypsinogen test than patients without a fistula (11 of 12 versus five of 38; P < 0·001).

Conclusion

This study suggests that the urine trypsinogen strip test might be a valuable method for diagnosis of pancreatitis after pancreatic surgery.

Computational Fluid Dynamics‐ Simulation der Ein‐ und Zweiphasenströmung in einer Rotating Disc Contactor‐Extraktionskolonne
Authors: Drumm C. , Bart H.‐J.
Published: October 2006

Die Ein‐ und Zweiphasenströmung in einer Rotating Disc Contactor‐Extraktionskolonne wird mit dem kommerziellen Computational Fluid Dynamics‐Code Fluent simuliert. Im einphasigen Fall werden mehrere Turbulenzmodelle und Gittergeometrien getestet, um eine Grundlage für die zweiphasige Simulation zu schaffen, in der ein Euler‐Euler‐Modell eingesetzt wird. Die CFD‐Simulationen werden mit experimentellen Particle Image Velocimetry‐Daten validiert, wobei im zweiphasigen Betrieb ein isooptisches Stoffsystem verwendet wird. Es zeigt sich, dass die durchgeführten CFD‐Simulationen die Strömung der Phasen in einer Extraktionskolonne detailgenau in hoher Auflösung wiedergeben.

Harmonic oscillators realized using current amplifiers and grounded capacitors
Authors: Souliotis George , Psychalinos Costas
Published: October 2006

New configurations of harmonic oscillators, realized using current amplifier blocks and only grounded capacitors, are introduced in this article. The proposed configurations are based on a grounded inductor simulator scheme and on a loop constructed from first‐order sections, respectively. Comparison with the already published topologies shows that the new configurations have attractive characteristics concerning their implementation in integrated form.
