Not Just a Sign: In what Ways can Semiotics be used to Contribute to Contemporary Rebranding Design?
Authors: Lu Yao
Published: February 2025

We are fortunate to live in a world of rapid development, where at meantime people are increasingly unwilling to look beyond the surface to understand the nature of things, which is also a misfortune. Nowadays people see something, they are no longer thinking about the meaning but are just attracted by its appearance and forget it in a twinkling. Brand owners have to comply with the visual habits of human beings and refresh outdated brands by constantly designing a more eye-catching visual identity than before. Simplicity has become a true dogma over the years. Logos are also constantly designed and modified into a simpler shape… The business working through the concept of rebranding itself may ask the following questions: “Is this really a good sign that we are changing and moving forward to a better era?  Is this an appropriate time for such substantive work? Are we discussing a soft evolution or metamorphosis? Does this rebranding address a clearly identified problem, and can it represent a genuine asset for making a progress” (Debit, 2017)? The content of this thesis explores this complex semiotic system running behind contemporary rebranding design. We started with this question: In what ways can semiotics be used to contribute to contemporary rebranding design? The research methods employed to resolve this question consisted of essays on semiotics, key readings on world best rebranding projects as well as case studies of particular branding company. This discussion brought us to several conclusions: Firstly, based on evolutionary knowledge of human visual habits, such as Gestalt Psychology and Selective Attention, we know that humans are creatures who only see what they want to see. In terms of this incontrovertible fact, can semiotics build its own temple on it. Secondly, the Functional Matrix system in Semiotics enables rebranding design to have the more possibility to survive in today’s market. In other words, Semiotics brings rebranding design the foreground, makes it more explicit, memorable, recognizable and gives it more protection to keep up with the changing times (Skaggs, 2017). Lastly, the Cultural Symbolism system in Semiotics enables the logotypes in rebranding design have universal power over time. That is to say, no matter which country this rebranding design goes to, it can always be successfully recognized.

The Impact of Regional Green Finance Development Level on Green Total Factor Productivity of Enterprises: An Empirical Study Based on A-Share Listed Companies
Authors: Jin Rongda
Published: February 2025

This paper uses the data of Chinese A-share listed companies from 2009 to 2021 to explore the impact of green finance development on the green total factor productivity performance of enterprises. The research finds that the regional green finance development level improves the green total factor productivity of enterprises by guiding them to enhance their green technological progress. The above results have conditional heterogeneity, and the administrative regulation level and market regulation level of regional governments have different moderating effects on the improvement of enterprise green total factor productivity. The mechanism analysis shows that regional green finance development affects the green total factor productivity level of enterprises by promoting their green technological progress. The impact of green finance on enterprises with different characteristics varies. Enterprises located in the eastern region are more likely to be affected by regional green finance development. Labor-intensive and technology-intensive enterprises are both significantly affected. Private and foreign-funded enterprises are more significantly affected than state-owned enterprises. Further inter-group difference analysis reveals that labor-intensive enterprises and private enterprises are more likely to be affected by green finance development. The policy implications of the research conclusions of this paper are as follows: It is necessary to further improve the green credit policy system, pay attention to the impact of government behavior on the implementation effect of policies, and strengthen the amplification effect of market-based regulations mainly based on environmental taxes. At the same time, it is necessary to focus on cultivating the internal environmental governance awareness of enterprises, promote the green coordinated development of different types of enterprises, improve resource allocation in both stock and flow aspects, promote the transformation and upgrading of enterprises, and the green coordinated development of society.

Authors: Xie Jiajia
Published: February 2025

Edward once stated, "Creativity is the most important human resource; without creativity, there is no progress." The China Basic Education Association has also emphasized in educational forums the importance of cultivating top-tier innovative talents. Such talents rely heavily on the stimulation of students' innovative thinking and the development of creativity. Currently, some kindergartens exhibit a trend of primary school-oriented practices, focusing excessively on knowledge transmission while neglecting the cultivation of comprehensive qualities, particularly creativity. Moreover, the unidirectional approach to the kindergarten-primary school transition results in weak connections between kindergarten and primary school, making it difficult to form an effective synergy. Therefore, this study, based on the context of curriculum gamification, explores effective strategies for cultivating creativity during the kindergarten-primary school transition. The goal is to understand the intrinsic logic between curriculum gamification and the development of creativity, enabling children to continuously enhance their creativity and stimulate innovative thinking through play.

Electricity Consumption Data Quality Improvement Based on Low-Rank Matrix Decomposition
Authors: Xu Guo , Zeng Xuyang , Ma Tianyu , Xu Jianjun
Published: February 2025

Measurement data from smart meters can be affected by issues such as missing values and noise due to communication problems, power fluctuations, or interference. These anomalies reduce the reliability and utility of electricity consumption data, thereby hindering the efficient operation of power systems. To address the issues of missing data and noisy anomalies in electricity consumption data, this paper proposes a low-rank matrix recovery model based on the truncated nuclear norm. By leveraging the low-rank property inherent in electricity consumption data, the truncated nuclear norm is used as an approximation of the matrix rank. Simultaneously, the L1- norm is employed to constrain the sparse noise, enabling the completion of the low-rank components and the separation of sparse components. Finally, a two-step iterative strategy based on the alternating direction method of multipliers (ADMM) is applied to solve the model. Comparative experiments conducted on real datasets against commonly used methods for missing data imputation demonstrate the effectiveness of the proposed approach.
Study on Effect of Liquid CO2 Blasting Crack Propagation in Coal Rock with Natural Fissure based on ANSYS/LS-DYNA
Authors: Zhang Wenzhou , Li Liankang
Published: February 2025

In order to study the influence of natural cracks in rock mass on the blasting effect of liquid CO2, and to better promote this technology, the law of energy propagation and crack propagation after blasting of liquid CO2 in coal rock mass containing natural cracks was studied based on ANSYS/LS-DYNA numerical simulation software. The results show that natural cracks in coal and rock will block the energy propagation after liquid CO2 blasting, reflect most of the stress wave energy, and form a crushing zone of 49.6cm×10.6cm in front of natural cracks in coal and rock. Stress concentration occurs at the tip of the natural crack, forming the initial guide crack, changing the direction of crack development. The crack develops along the direction perpendicular to the natural crack of coal rock mass, and the final shape of crack growth is 69.8cm. The research results can provide a theoretical basis for the determination of the actual blasting scheme.

Authors: Yang Yuanliang
Published: February 2025

Pai 10 West Oilfield, located in the west of Chunguang Oilfield, is a typical medium and high permeability thin oil lithologic reservoir, with serious sand production problems, and the traditional mechanical sand control technology has a short validity period, which cannot meet the long-term development needs of this block. In order to solve this problem, a high-strength self-emulsifying sand fixing agent system (HCS) based on epoxy resin was developed in this paper, and its performance under complex geological conditions was verified by experiments. In the experiment, the performance of the sand fixing agent was comprehensively evaluated by sand particle sieve analysis, sand filter performance test, bottomhole environment simulation, anti-aging and anti-erosion experiments. The results show that the sand fixing agent can effectively form a uniform cladding layer, significantly improve the consolidation strength of sand particles, and maintain excellent compressive strength and permeability in high temperature, high pressure and complex downhole environment, with excellent erosion resistance. In addition, the sand fixing agent exhibits excellent anti-aging ability and can maintain high strength and stability over a long period of time. The research results of this paper provide an innovative technical scheme for efficient sand control in Pai 10 West Block, and also provide a reference for the sand production problem of similar high-permeability reservoirs.

Study on Numerical Simulation of Reservoir Fine Water Injection Development Considering Reservoir Heterogeneity
Authors: Zhang Bingyong
Published: February 2025

Reservoir heterogeneity includes macroscopic interlayer, intralayer and plane heterogeneity, as well as microscopic differences in pore structure and wettability, which significantly affect water flooding efficiency and remaining oil distribution. By collecting geological, dynamic and rock fluid data, a fine geological model is constructed, and the reservoir characteristics are accurately described by using mixed grid strategy and discrete fracture network model. In the numerical simulation, the black oil model considering the influence of dissolved gas is selected and the non-Darcy flow is modified. In the design of development scheme, the water injection mode, water injection horizon selection, dynamic control of water injection speed and injection-production ratio optimization strategy are optimized. The results show that the oil recovery is increased by 6.2% by stratified controlled water injection compared with uniform water injection, and the oil recovery is further increased by 2.5% by dynamic optimization scheme. Reservoir heterogeneity has a significant impact on the development effect. For every 0.1 increase in permeability variation coefficient, the sweep efficiency of water flooding decreases by about 8%. Through dynamic injection-production regulation and intelligent separate injection technology, the optimization scheme has significantly improved the oil recovery and economic benefits.
Sui βασιλικοὶ λόγοι di Michele Psello: note propedeutiche a una nuova edizione critica
Authors: Longhi Alberto
Published: February 2025

I ventuno βασιλικοὶ λόγοι scritti e pronunciati da Michele Psello (1018 – 1078), inediti fino alla seconda metà del XIX secolo, hanno visto diverse edizioni principi fino agli anni Ottanta del secolo scorso; furono riuniti in un unico volume teubneriano nel 1994, per cura di George T. Dennis, sotto il titolo di Orationes panegyricae; sebbene questo volume sia tutt’oggi l’edizione di riferimento per gli encomi pselliani, esso consta di numerose problematicità: ordine delle orazioni non corrispondente a quello cronologico, assenza di altre cinque orazioni (tuttavia presenti negli Oratoria minora curati da Littlewood), frequentissime letture errate dai manoscritti e un apparato delle fonti che spesso travisa gli intenti dell’autore. Con l’ausilio dei numerosi studi su Psello pubblicati nel corso degli ultimi vent’anni, l’intento del presente contributo è fornire uno studio preparatorio per una nuova edizione critica, evidenziando e superando tutte le problematicità delle precedenti edizioni teubneriane.
(E)rudimentum doctrinae: una nomenclatura per l’insegnamento. Con un’appendice sul titolo del lessico di papias
Authors: Artemisio Francesca
Published: February 2025

L’opera maggiore di Gilberto di Tournai è curiosamente provvista di un duplice titolo:Rudimentum o Erudimentum doctrinae. Di tale doppia denominazione Gilberto dà notizia nella prefazione, senza tuttavia offrire motivazioni aggiuntive che ne chiariscano il senso. La questione è sinora passata quasi del tutto inosservata, ma la rarità del termine erudimentum invita ad una riflessione che superi l’ipotesi di un banale gioco paronimico. A partire dunque dall’escussione delle attestazioni del termine, il contributo si propone di ricostruirne il campo semantico, per comprenderne il valore in relazione al titolo complessivo dell’opera, alle intenzioni programmatiche di Gilberto e all’unico precedente noto al quale egli poteva mirare, l’Elementarium Doctrinae (E)rudimentum di Papias. Per ragioni diverse, anche il titolo dell’opera di Papias è stato oggetto di una lunga diatriba tra gli studiosi, ma dalla collazione tra i testimoni più autorevoli dell’Elementarium – qui offerta in appendice – è finalmente possibile fornire un chiarimento definitivo sull’effettiva denominazione del lessico.

This study aims to analyze the influence of learning motivation, learning independence, executive function, and confidence on students' mathematical literacy skills. This research is a quantitative research. The research sample consisted of a number of high school students who were selected through random sampling techniques. Data were collected through questionnaires and mathematical literacy tests, then analyzed for path analysis to determine the contribution of each independent variable to the dependent variable. The results showed that there was a significant influence between learning motivation, learning independence, executive function, and confidence on students' mathematical literacy skills, both partially and simultaneously. There is an influence between learning motivation, learning independence, and self-confidence directly on executive function. Literacy ability is directly influenced by executive function and learning motivation significantly. Meanwhile, learning independence and self-confidence do not have a significant direct effect on mathematical literacy skills. However, learning independence and self-confidence affect mathematical literacy skills indirectly through executive functions. These findings show that strengthening psychological and cognitive factors is indispensable in improving students' mathematical literacy.

Results: The findings revealed that 46.5% of hypertensive patients exhibited depressive symptoms, with an average PHQ-9 score of 10.11 ± 5.13. Among them, 26.5% had mild depressive symptoms, 13.9% had moderate symptoms, and 6.1% had severe depression. Significant factors associated with depressive symptoms included age, gender, marital status, duration of hypertension treatment, and comorbidities (p < 0.05).
Conclusion: Nearly one in two hypertensive patients exhibited depressive symptoms, with the average severity classified as mild. These findings emphasize the importance of integrating routine depression screening into hypertensive patient care. Healthcare providers, especially nurses, should actively monitor the psychological well-being of hypertensive patients and implement targeted interventions to enhance overall patient outcomes.
Evaluacion del estado nutricional de ninos de la calle (Programa casa alianza), diferenciado por etapa de desarrollo
Authors: Morán Molina
Published: February 2025

El presente trabajo se realizó con el propósito de conocer la situación del estado nutricional de los niños de la calle, ya que a la fecha no existen trabajos similares, datos que pueden ser una base para que se realicen estudios en poblaciones de similar condición.
 
El estudio se llevó a cabo en el programa de Casa Alianza, institución de desarrollo que se dedica a los niños de la calle (1,2), con niños comprendidos entre los 9 y 18 años de edad de ambos sexos, que saben leer y escribir y que de manera anónima y voluntaria desearon participar.
 
En la metodología utilizada se utilizó un cuestionario de datos antropométricos (peso, talla, edad, sexo) y de fases de desarrollo sexual según la clasificación de Tanner. La primera parte del mismo fue llenado en base a los datos obtenidos por el investigador y la segunda parte constó de una autoevaluación.
 
El análisis de los datos se realizó por medio del análisis de varianza y análisis de correlación, a manera de encontrar la relación entre el estado nutricional y la fase de desarrollo sexual de los niños.
 
Al evaluar el estado nutricional según el índice de masa muscular se encontró que la mayoría clasificaron en el índice ideal, al igual al ser comparados con las variables de: etapa del programa, sexo y etapa de desarrollo sexual.
Análisis multielemental por reflexión total de rayos X, en tejido muscular de lobina Micropterus salmoides (lacepade) y guapote Ciclhasoma maneguense (Gunter), en la laguna de Chichoj, San Cristobal Verapaz, Alta Verapaz

En el presente trabajo se determinó la concentración de metales en el músculo liso de Micropeturs salmoides (lobina) y Cichlasoma managuense (guapote), dos de las especies ictiofaunísticas que se encuentran en la laguna de Chichoj en San Cristóbal Verapaz, Alta Verapaz, que son las más consumidas por la población.
 
La técnica utilizada en las determinaciones fue la de Fluorescencia de Rayos X por Reflexión Total. Se efectuaron 4 muéstreos en los meses de mayor actividad industrial y por tanto de mayor descarga de contaminantes al cuerpo de agua en cuestión, siendo éstos noviembre y diciembre de 1993, enero y febrero de 1994. En base a estudios anteriores se establecieron dos puntos de muestreo, en los cuales fueron colectados 3 especímenes de cada especie y con un r=2. A estos individuos se les extrajo el músculo, el cual fue pesado, secado a 60 grados centígrados y molido y digerido, previo al análisis por reflexión de rayos x.
 
Los metales detectados fueron K, Ca, Fe, Cu, Zn, Rb, Sr, Pb. No se encontraron diferencias estadísticamente significativas, con un valor de P = 0.0001, utilizando un alfa de 0.05, entre los dos puntos de muestreo para los elemen tos detectados, excepto en el caso del plomo, y no se encontraron diferencias entre las dos especies estudiadas.
 
La concentración de los elementos detectados reporta ron diferencias estadísticas significativas, básicamente en los meses de muestreo, siendo el mes de enero el que presentó concentraciones más altas de Cu, Fe y Sr, el mes de febrero reportó concentraciones más altas de K, Pb, Zn y Rb y el mes de noviembre las más altas de Cu.
 
Los valores de concentraciones de Pb encontrados en el músculo de los peces sobrepasan el índice semanal tolerable. Los Valores de Zn, Cu y Fe sobrepasan la dosis diaria máxima admisible. Por lo anterior, se concluye que las especies M. salmoides y C. managuense de la laguna de Chichoj son un riesgo para la salud.
Cuantificación de carotenoides precursores de vitamina A en fuentes vegetales de consumo en Guatemala
Authors: Padilla Aura , Padilla Gerardo
Published: February 2025

El objetivo de este estudio fue evaluar la influencia de diferentes tipos de almacenamiento del Brássica olerácea (brócoli) variedad itálica Plenck, sobre la variación del conteni do de p-caroteno, el cual es un precursor de vitamina A.
 
La carencia de vitamina A consti tuye uno de los más graves problemas de salud pública en Guatemala, por lo que el estudio para preservar  P-caroteno en productos naturales propios de la región que sean fuentes de dicha vitamina, es de suma importancia.
 
Las variables estudiadas fueron: empaque con película de PVC de 60 gage, escaldado y temperatura de almacenaje a 5°C y 15°C. La combi nación de estas tres variables dio como resultado 8 diferentes tipos de almacenaje los cuales fueron analiza dos en este estudio. Se utilizó brócoli de especie Marathon proveniente de Mataquescuintla Jalapa, Guatemala.
 
Las muestras a 5°C se almacena ron en un refrigerador Lab-line, Ambi-Hi-lo chamber modelo 3550 y las muestras a 15°C en un refrigera dor Tyler, modelo XS40 EEC.
 
La determinación del contenido de p-caroteno se hizo mediante el método de Rodríguez-Amaya que involucra cromatografía en columna abierta y HPLC, cada muestra por triplicado siendo expresados los datos en ug/100 gr. de muestra seca.
 
Los resultados muestran que en el rango de temperaturas estudiado, el empaque en película de PVC es la única variable que influye considera blemente en la preservación del contenido de p-caroteno en el brócoli.
 
Se recomienda utilizar para la mínima variación en el contenido de P-caroteno un proceso de empaque con escaldado, empacado con película de PVC y almacenado a una temperatura de 5°C si se desea consumir antes de 216 horas, con una pérdida del 0.24% del contenido de p-caro teno.
 
Estos procesos se recomiendan para el uso en la industria de alimentos como método alterno al común mente utilizado para el procesamiento del brócoli.
 
El resto de los procesos de almacenaje no dieron como resultado un producto lo suficientemente bueno como para comercializar con él.
