Purpose

This study aimed to evaluate patellar tendon loading profiles (loading index, based on loading peak, loading impulse, and loading rate) of rehabilitation exercises to develop clinical guidelines to incrementally increase the rate and magnitude of patellar tendon loading during rehabilitation.

Methods

Twenty healthy adults (10 females/10 males, 25.9 ± 5.7 yr) performed 35 rehabilitation exercises, including different variations of squats, lunge, jumps, hops, landings, running, and sports specific tasks. Kinematic and kinetic data were collected, and a patellar tendon loading index was determined for each exercise using a weighted sum of loading peak, loading rate, and cumulative loading impulse. Then the exercises were ranked, according to the loading index, into tier 1 (loading index ≤0.33), tier 2 (0.33 < loading index <0.66), and tier 3 (loading index ≥0.66).

Results

The single-leg decline squat showed the highest loading index (0.747). Other tier 3 exercises included single-leg forward hop (0.666), single-leg countermovement jump (0.711), and running cut (0.725). The Spanish squat was categorized as a tier 2 exercise (0.563), as was running (0.612), double-leg countermovement jump (0.610), single-leg drop vertical jump (0.599), single-leg full squat (0.580), double-leg drop vertical jump (0.563), lunge (0.471), double-leg full squat (0.428), single-leg 60° squat (0.411), and Bulgarian squat (0.406). Tier 1 exercises included 20 cm step up (0.187), 20 cm step down (0.288), 30 cm step up (0.321), and double-leg 60° squat (0.224).

Conclusions

Three patellar tendon loading tiers were established based on a combination of loading peak, loading impulse, and loading rate. Clinicians may use these loading tiers as a guide to progressively increase patellar tendon loading during the rehabilitation of patients with patellar tendon disorders and after anterior cruciate ligament reconstruction using the bone–patellar tendon–bone graft.

Η αντιδραστικότητα των αιμοπεταλίων σε ασθενείς που λαμβάνουν αντιρετροϊκή αγωγή
Authors: Κολόσακα Μάρθα
Published: October 2023

ΕΙΣΑΓΩΓΗ – ΣΚΟΠΟΣ : Οι ασθενείς με HIV λοίμωξη (PLWHIV) παρουσιάζουν αυξημένο κίνδυνο ανεπιθύμητων καρδιαγγειακών συμβαμάτων. Σκοπός μας ήταν να αξιολογήσουμε, εάν η αντιρετροϊκή θεραπεία (ART) ενισχύει την αντιδραστικότητα των αιμοπεταλίων και το βαθμό της ενεργοποίησής τους, και να διερευνήσουμε την πιθανή συσχέτιση με την υποκείμενη φλεγμονώδη κατάσταση. ΜΕΘΟΔΟΙ : Πρόκειται για μία μελέτη μεταξύ των HIV (+) ασθενών υπό διαφορετική αντιρετροϊκή αγωγή. Η αντιδραστικότητα των αιμοπεταλίων εκτιμήθηκε με τη μέθοδο της δοκιμασίας Verify Now, σε μονάδες αντίδρασης του υποδοχέα P2Y12 (P2Y12 reaction units ,PRU). Επίσης , αξιολογήθηκαν επίπεδα κύριων δεικτών φλεγμονής και άλλοι παράγοντες ολικού αίματος. ΑΠΟΤΕΛΕΣΜΑΤΑ : Συνολικά συμπεριλήφθηκαν στη μελέτη 71 PLWHIV , οι 59 υπό ART , και 22 υγιείς μάρτυρες. Οι τιμές PRU ήταν σημαντικά αυξημένες στους PLWHIV σε σύγκριση με τους μάρτυρες [Mean; 257.85 vs. 196.67, p < 0.0001]. Ωστόσο, δε φάνηκε σημαντική διαφορά μεταξύ των ασθενών που δε λάμβαναν ART και ασθενών υπό ART (ART-naïve or ART experienced), ή μεταξύ των PLWHIV υπό TAF/TDF ή ABC, παρόμοια με τη συστηματική φλεγμονώδη αντίδραση. Εν τούτοις , η ανάλυση εντός της ομάδας έδειξε σημαντικά υψηλότερες τιμές PRU στην ομάδα ABC+PI vs ABC+INSTI ή TAF/TDF +PI σύμφωνα με τα επίπεδα της IL-2. Οι τιμές PRU δε συσχετίσθηκαν έντονα με τον αριθμό των CD4 κυττάρων, το ιϊκό φορτίο και τις τιμές των κυτοκινών. H αντιδραστικότητα των αιμοπεταλίων και ο βαθμός ενεργοποίησής τους ήταν αυξημένες στους PLWHIV, αλλά δε φάνηκε να συσχετίζονται με την έναρξη της ART, παρόμοια με την υποκείμενη συστηματική φλεγμονώδη αντίδραση. ΣΥΜΠΕΡΑΣΜΑΤΑ: Η λοίμωξη από τον ιό HIV καθεαυτή, καθώς και η ART, έχουν συσχετιστεί με αυξημένο θρομβωτικό κίνδυνο, οδηγώντας σε δυσμενή καρδιαγγειακά συμβάντα. Οι υποκείμενοι μηχανισμοί που οδηγούν σε αυτό το φαινόμενο παραμένουν άγνωστοι, ενώ ο ρόλος των αιμοπεταλίων βρίσκεται επί του παρόντος υπό διερεύνηση. Διαπιστώσαμε αυξημένη ενεργοποίηση των αιμοπεταλίων στους PLWHIV, παρόλο που η δραστηριότητα των αιμοπεταλίων, όπως εξετάστηκε εδώ, δεν φαίνεται να διαφέρει σημαντικά μεταξύ των συνδυασμών με βάση TAF/TDF και ABC, ωθώντας το ενδιαφέρον σε άλλα μονοπάτια και μεσολαβητές. Σε αυτό το πλαίσιο, θα άξιζε να αναρωτηθεί κανείς αν στους PLWHIV χωρίς αυξημένο καρδιαγγειακό κίνδυνο, αλλά με αυξημένη ενεργοποίηση των αιμοπεταλίων, η χρήση αντιαιμοπεταλιακών θα ήταν επωφελής, όπως στην οξεία βακτηριακή λοίμωξη. Ή, αν θα ήταν απαραίτητη η αυξημένη δόση ή η χρήση πιο ισχυρών αντιαιμοπεταλιακών σχημάτων σε ασθενείς με ιστορικό καρδιαγγειακής νόσου ή που λαμβάνουν PIs, ενόψει των πρόσφατων ευρημάτων υψηλής αντιδραστικότητας των αιμοπεταλίων κατά τη θεραπεία σε PLWHIV. Το κατά πόσον η αντιδραστικότητα των αιμοπεταλίων και η ένταση της ενεργοποίησης θα μπορούσαν στο μέλλον να αποτελέσουν αξιόπιστο υποκατάστατο δείκτη για μείζονα ανεπιθύμητα καρδιαγγειακά συμβάματα μένει να αποδειχθεί.

Authors: Talapatra Arjun , Mathew Shaji , Kanakalakshmi Sushma Thimmaiah , Rani Rama
Published: October 2023

Background: Post-operative sore throat (POST) is one of the most common complaints post-endotracheal intubation and can be decreased through various interventions. This study aimed to determine the effect of fluticasone-impregnated versus saline throat packs on the occurrence and severity of POST and voice hoarseness.

Methods: This prospective, randomized, double-blinded trial was conducted on patients undergoing nasosinus surgeries at Kasturba Medical College and Hospital. Patients were randomized to groups based on a computer-generated table of random numbers post-intubation after placing a definite length of oropharyngeal packs into group F (fluticasone) who received four puffs of fluticasone furoate-soaked throat packs and group C (control) wherein normal saline-soaked throat packs were used. Determining the incidence of POST and voice hoarseness was the primary outcome; severity of POST and voice hoarseness, patient satisfaction scores at 24 hours post-surgery and adverse events were secondary outcomes.

Results: Overall, 86 patients were randomized and 43 patients were included in each group. Incidence of POST (%) and voice hoarseness (%) were 55.8, 55.6, 55.8, 53.4 and 30.2, 28, 28, 28 in group C. Incidence of POST (%) and voice hoarseness (%) were 37.2, 37.2, 37.2, 34.8 and 14, 14, 14,14 in group F at 1, 2, 6 and 24 hours, respectively, however, the p values were not found to be significant at any time interval. There was no significant difference in terms of severity of POST and voice hoarseness, patient satisfaction scores between the groups and there were no reported adverse events.

Conclusions: In patients undergoing nasosinus surgery under general anesthesia with endotracheal intubation, fluticasone furoate-impregnated throat packs failed to show any significant reduction in the incidence and severity of POST as well as hoarseness of voice, and even though it was not statistically significant, the fluticasone impregnated group had higher patient satisfaction scores.

The Republic of Cuba
Authors: Berbeć Dawid
Published: October 2023

The moment when Fidel Castro entered Havana in January of 1959 irreversibly changed the course of Cuban history. Due to its geographical proximity to the United States of America, Cuba was always present in Washington’s foreign policy agenda, which made this Caribbean country highly vulnerable to American influence. One of the results of the Cuban Revolution was the pursue for the unlimited sovereignty and autonomy from any imperial power. Cubans have succeeded in it only partially: while no other country could interfere in their internal affairs any longer, during the Cold War they heavily relied on Soviet Union’s support and since the early 1960s until now Cuba is a subject of a strong economic and political pressure of the USA. The aim of the article is to examine the historical roots of Cuban nondemocratic mechanisms, as well as present the process of political system evolution and ideological principles of the regime. Moreover, the author highlights the significance of impact of imperialism and Cold War politics on Cuban society and economy.
How Does Online Information Influence Offline Transactions? Insights from Digital Real Estate Platforms
Authors: Jiang Zhengrui , Rai Arun , Sun Hua , Nie Cheng , Hu Yuheng
Published: October 2023

This study highlights the critical function that digital real estate platforms, like Zillow, serve in facilitating effective property transactions. They do this by transmitting vital property information from sellers to buyers, thereby enriching the value of offline deals. Our findings indicate that Zillow, as a source of information, is incredibly valuable for properties that deviate significantly from their neighborhood’s average value, either above or below. It’s particularly useful in conveying experiential details through images and textual descriptions. For potential buyers, Zillow is a trustworthy source of property information for estimating property value, especially when alternative sources of information are limited. This study underscores the necessity for sellers and their agents to effectively represent property information online, considering its significant impact on sale prices. This is especially true for unique properties and properties with notable experiential elements. Furthermore, our study suggests that real estate professionals need to modify their business practices to take full advantage of digital platforms and provide superior services to their clients. Finally, digital real estate platforms can use these insights to enhance their platform design by focusing on the collection and display of significant information, ultimately increasing the value provided to both buyers and sellers of properties.
The Editor and the Algorithm: Recommendation Technology in Online News
Authors: Peukert Christian , Sen Ananya , Claussen Jörg
Published: October 2023

We run a field experiment to study the relative performance of human curation and automated personalized recommendation technology in the context of online news. We build a simple theoretical model that captures the relative efficacy of personalized algorithmic recommendations and curation based on human expertise. We highlight a critical tension between detailed, yet potentially narrow, information available to the algorithm versus broad (often private), but not scalable, information available to the human editor. Empirically, we show that, on average, algorithmic recommendations can outperform human curation with respect to clicks, but there is significant heterogeneity in this treatment effect. The human editor performs relatively better in the absence of sufficient personal data and when there is greater variation in preferences. These results suggest that reverting to human curation can mitigate the drawbacks of personalized algorithmic recommendations. Our computations show that the optimal combination of human curation and automated recommendation technology can lead to an increase of up to 13% in clicks. In absolute terms, we provide thresholds for when the estimated gains are larger than our estimate of implementation costs.

Popularity Bias in Online Dating Platforms: Theory and Empirical Evidence
Authors: Celdir Musa Eren , Cho Soo-Haeng , Hwang Elina H.
Published: October 2023

Problem definition: Generating recommendations of compatible dating partners is a challenging task for online dating platforms because uncovering users’ idiosyncratic preferences is difficult. Thus, platforms tend to recommend popular users to others more frequently than unpopular users. This paper studies such popularity bias in an online dating platform’s recommendations and its consequences for users’ likelihood of finding dating partners. Methodology/results: Motivated by the empirical evidence that a user’s chance of being recommended by the platform’s algorithm increases significantly with the user’s popularity, we study an online dating platform’s incentive that generates popularity bias by modeling the platform’s recommendations and users’ subsequent interactions in a three-stage matching game. Our analysis shows that the recommendations that maximize the platform’s revenue and those that maximize the number of successful matches between users are not necessarily at odds, even though the former leads to a higher bias against unpopular users. Unbiased recommendations result in significantly lower revenue for the platform and fewer matches when users’ implicit cost of evaluating incoming messages is low. Popular users help the platform generate more revenue and a higher number of successful matches as long as these popular users do not become “out of reach.” We validate our theoretical results by running simulations of the platform based on a machine learning–based predictive model that estimates users’ behavior. Managerial implications: Our result indicates that an online dating platform can increase revenue and users’ chances of finding dating partners simultaneously with a certain degree of bias against unpopular users. Online dating platforms can use our theoretical results to understand user behavior and our predictive model to improve their recommendation systems (e.g., by selecting a set of users leading to the highest probabilities of matching or other revenue-generating interactions).

Technical Note—Improved Sample-Complexity Bounds in Stochastic Optimization
Authors: Baveja Alok , Chavan Amit , Nikiforov Andrei , Srinivasan Aravind , Xu Pan
Published: October 2023

Faster Methods to Handle Optimization Problems That Display Uncertainty

In the paper “Improved Sample-Complexity Bounds in Stochastic Optimization,” the authors Alok Baveja, Amit Chavan, Andrei Nikiforov, Aravind Srinivasan, and Pan Xu consider a classic approach to modeling uncertainty in optimization problems—stochastic optimization. A general way to model such uncertainty is to assume access to a probability distribution from which the different possible scenarios of an optimization problem can be sampled; a powerful way to work with such access is to sample explicit scenarios a fixed number of times and to then “average over” all these explicit deterministic scenarios. The key question then becomes as follows. How many such scenarios should be sampled? By a careful analysis, this work shows that the number of samples needed is much less than known before, thus speeding up several algorithms for stochastic-optimization problems.

Authors: Choi Sujin , Kim Ju Eun , Sung Jee Eun
Published: October 2023

Objectives: A naming deficit is a common linguistic issue for individuals with aphasia. Semantic Feature Analysis (SFA) is a widely used approach to improving the naming abilities of individuals with aphasia. The purpose of this study was to develop a Korean version of the semantic feature database used in SFA treatment. Methods: The item lists and semantic features of nouns and verbs were modified to reflect the linguistic characteristics and cultural context of Korea. To assess the semantic relatedness of the items and semantic features, the researchers conducted two validation studies. In the first study, forty young participants were recruited, and the semantic features were revised if the agreement rate was less than 80%. In the second study, sixteen speech language pathologists participated. Results: The final list included 213 nouns and 159 verbs, with 24 semantic features for each word. The researchers composed 5,112 noun semantic features and 3,816 verb semantic features. In the first validation, the matching rate of semantic features was over 80%, except for 21 noun semantic features and 167 verb semantic features. In the second validation, 21 noun semantic features and 161 verb semantic features showed a matching rate of over 80%. The researchers modified six verb semantic features with a matching rate of less than 80%. Conclusion: This study successfully developed a Korean version of the semantic feature database for noun and verb naming treatment. This database provides a valuable resource for improving the naming abilities of individuals with aphasia.
Development and Applied Research of Korean-Index of Phonetic Complexity-Revision (K-IPC-R)
Authors: Lee Ran , Han Jinsoon , Lee Eun-ju
Published: October 2023

Objectives: In this paper, the Korean-Index of phonetic complexity-revision (K-IPC-R) was revised and supplemented to use the Korean-Index of phonetic complexity (K-IPC; Lee, Han, Shim, 2004) as a phonological evaluation index of the independent analysis method. Methods: Speech samples of 20 typically developing children of 18 to 23 months, 24 to 29 months, and 30 to 35 months of age were collected from each child during spontaneous play. The analizing and scoring criteria of K-IPC-R were devised on the basis of the phonological characteristics found in the speech samples and the results of previous studies related to speech sound development. Results: The K-IPC-R was composed of nine sub-indices: consonant by place class, consonant by manner class, consonant by phonation type, vowel type, shape of syllables, length of syllables, singleton consonants by place variegation, presence of consonant chain, and consonant chain type. The scoring criteria were determined to weight 1 point to velars, fricatives, affricates, liquids, aspirated, diphthongs, closed syllable words, and three or more syllable words. And 1 point is weighted when two or more consonants with different place of articulation are present within a word. Also, 1 point is weighted if a consonant chain appeared and another 1 point is weighted if the place of articulation of the chained consonants are different. Conclusion: This study is meaningful in proposing the K-IPC-R as a phonological evaluation index of an independent analysis method that can evaluate the phonological ability of children at the initial level of phonological development, whose phonological ability is difficult to evaluate with a relational analysis method.
Meta-analysis of Stuttering Prevalence and Incidence
Authors: Lee Kyungjae
Published: October 2023

Objectives: Stuttering prevalence and incidence can be measured in very diverse ways and such differences in methodologies may contribute to variability of the results. Moreover stuttering prevalence and incidence can be different according to factors such as gender and age. The current study tried to provide a comprehensive view on stuttering prevalence and incidence through meta-analysis of the research results. We also tried to determine whether stuttering prevalence and incidence would be different according to gender, age, and region. Methods: A total of four databases (two Korean and two English databases) were used in the current study for article search. A total of 27 articles (26 English, 1 Korean) met the inclusion/exclusion criteria and were analyzed in the current study. Results: Overall stuttering prevalence was about 1.5% and overall stuttering incidence was about 3.9%. There was a statistically significant difference in stuttering prevalence according to gender and age. Stuttering prevalence for males and preschoolers was almost twice as much as that of females and other age groups. However there was no significant difference in prevalence according to regions. Furthermore there was no significant difference in stuttering incidence according to gender. Conclusion: The meta-analysis results of the current study showed very similar, but still somewhat different stuttering prevalence and incidence compared to the commonly held belief. Such differences may be due to the typical characteristics of the studies analyzed in the current study. There may be future studies on more diverse factors that influence stuttering prevalence and incidence.

Authors: Baik Kyungrang , Kim Kyungyang , Park Eunhye , Kim Young Tae
Published: October 2023

Objectives: With advancements in scientific and technological progress, various Augmentative and Alternative Communication (AAC) applications (apps) have been developed. AAC users require AAC systems that align with their personal characteristics and needs. AAC performance indicators, which encompass usability evaluation, aim to measure communication effectiveness and satisfaction. These indicators can be utilized to assist AAC users in selecting appropriate AAC systems. The goal of this study was to develop performance indicators that would allow AAC users and stakeholders to evaluate AAC apps from multiple perspectives. Methods: Mobile apps and usability evaluations in prior studies were analyzed to extract keywords. Performance indicator items were developed based on this analysis. Expert validity was evaluated, and a survey of AAC users and stakeholders was done to adjust the number of items included and measure validity and reliability. Results: The analysis of prior studies for the development of performance indicator items was visualized in the form of a word cloud. The reliability assessment of AAC app performance indicators yielded a Cronbach’s α value of 0.9 or higher. Regarding content validity, the expert validity showed an S-CVI of 0.978, while the survey with AAC users and stakeholders resulted in 0.754. Exploratory factor analysis was performed to assess construct validity, revealing that all variables demonstrated a communalities value of 0.4 or higher. The items were categorized into five factors: usability, social communication, user-centered design, adoption, and empowerment. Conclusion: AAC app performance indicators should be user-centered, incorporating diverse perspectives and evaluating various aspects of app usage.

Authors: Lee Eunhye , Shin Sangeun
Published: October 2023

Objectives: This study aimed to examine the communication needs and communication functions required by adults with cerebral palsy and developmental disabilities in various activity support areas, with the goal of enhancing the effective operation of personal assistance services. Methods: A total of 30 personal assistants, who had experience assisting adults with communication difficulties due to cerebral palsy or developmental disabilities, were divided into two groups: 15 adults with cerebral palsy and 15 adults with developmental disabilities. They were assessed for communication needs using a 5-point Likert scale across nine areas of activity support (Personal hygiene, Body functions, Meal support, Moving indoors, Cleaning, Laundry, Cooking, Commuting, and Going out) and six communication functions (Requests, Responds, Objective comments, Statements, Acknowledge, and Organization devices). Results: The communication needs of the cerebral palsy group were significantly higher than those of the developmental disability group, with a main effect of the activity support domain and a significant interaction effect between disability type and activity support domain. While the cerebral palsy group did not differ in communication needs across the activity support domains, the developmental disability group had higher communication needs in the going out domain than in the body functions and moving indoors domains. The cerebral palsy group had higher scores in the communication functions than the developmental disability group, but neither group showed significant differences in scores between types of communication functions. Conclusion: Communication needs and functions and the need for communication support were discussed according to disability type and activity support domain.

Published: October 2023

Introduction: We present a case report concerning calcified chondroid mesenchymal neoplasms (CCMN), a novel category of tumors that exhibit chondroid formation and contain fibronectin 1-receptor tyrosine kinase fusions. Case Report: Our report focuses on a 73-year-old female patient who presented with pain in her right hip and gluteal region. Initially, the condition was misdiagnosed as calcific tendinitis based on X-ray imaging. However, a subsequent magnetic resonance imaging (MRI) revealed a solid lobulated mass originating from the right hamstring tendon origin, exhibiting heterogeneously hypointense T1-weighted signal, heterogeneously isointense proton density fat-suppressed signal, and heterogeneous contrast-enhancement compared to skeletal muscle. Further, investigation through computed tomography (CT) demonstrated intratumoral calcifications accompanied by erosive changes in the adjacent right ischial tuberosity. Histologic examination of a CT-guided biopsy confirmed the presence of large calcium pyrophosphate crystal deposits, along with benign chondroid tissue, thus supporting the diagnosis of CCMN. Notably, there is considerable overlap in the imaging characteristics of CCMN and the more commonly encountered calcific tendinitis (calcium hydroxyapatite depositional disease). Contrast-enhanced MRI findings play a crucial role in distinguishing between these two conditions. Conclusion: To the best of our knowledge, this is the first documented report describing the imaging features of CCMN across multiple modalities, including radiography, CT, and MRI. Keywords: Tumor, mass, hip.

Authors: S Sugiarto , Limanoond Thirayoot , Nakatsuji Takashi
Published: October 2023

Abstract - Dropped in traffic capacity and travel speed during congestion were studied at a u-turn section on an arterial road in Indonesia. Traffic characteristics during congestion were analyzed using oblique cumulative plots and breakdown method. Both approaches are time series treatment between cumulative vehicles arrival versus time contracted from data recorded by video tape. Studies were conducted in both morning and evening peak hours on three regular weekdays. This study found traffic breakdown condition during the peak periods; the breakdown lasted on average 40 minutes. It was found that capacity during traffic breakdown drops in the range 8-9 percent from the before-breakdown capacity. Similarly, during the breakdown, speed drops on average 10 percent from the before condition. Several alternatives were selected and tested for improving existing conditions. It was found that adding a 50m pocket lane would help improving the existing situation by reducing the delay to 69 percent, increasing speed to 39 percent, and improving capacity to 11 percent compared to the result of simulation an existing condition

Authors: - Ichwana , Nasution Zulkifli , - Sumono
Published: October 2023

Abstract - Volume of groundwater recharge showed a picture of a watershed to determine the flow instability due to the physical characteristics of the watershed and precipitation. Many methods had been constructed to understand the dynamic movement of water discharge. One of them was the analysis of the stream hydrograph with Seasonal Recession Method. Information about groundwater recharge condition at several sub watershed in Krueng Peusangan Watershed was really needed in management of watershed for sustainable water resources. The study aimed to determine groundwater recharge from stream flow with seasonal recession method was conducted in Krueng Peusangan watershed, Aceh Province, Indonesia. The results showed that the trend pattern of the stream hydrograph could be explained using the exponential function where the dots lowest discharge that is the end of the recession (y) than any period of time on stream hydrograph semi logarithmic (x). The pattern of results that occurred in the watershed of Krueng Peusangan: (A) Krueng Seumpo had a trend for y = 9.2x-0.35, (B) Simpang Jaya  for y = 559.7x-0.5, (C) Beukah village for y = 142x-0.32 , (D) Sub watershed of Lut Tawar (Wih Nareh) for y = 1.3x-0.12 and (E) Sub watershed of Teupin Mane (Krueng Teumbo) for y = 1.94x-0.42. It also showed that the location of A, B, C, E had a higher slope and a decreased recharge pattern compared to the location of D (sub watershed of  Lut Tawar)  that tended to flat. The volume of groundwater recharge that occurred in a region (A and D) increased while the other location was very volatile. Moreover, recharge instability occurred in Krueng Teumbo. Therefore, it needed a clear direction for land use and functions of forests, especially in the recharge area, in order to maintain the balance of the hydrological cycle, and the quantity of groundwater. Keywords: groundwater recharge, seasonal recession method, base flow, stream flow, water resources
Development of Rainfall-runoff Model Using Tank Model: Problems and Challenges in Province of Aceh, Indonesia
Authors: Basri Hairul
Published: October 2023

Abtstract - Rainfall-runoff model using tank model founded by Sugawara has been widely used in Asia. Many researchers use the tank model to predict water availability and flooding in a watershed. This paper describes the concept of rainfall-runoff model using tank model, discuss the problems and challenges in using of the model, especially in Province of Aceh, Indonesia and how to improve the outcome of simulation of tank model. Many factors affect the rainfall-runoff phenomena of a wide range of watershed include: soil types, land use types, rainfall, morphometry, geology and geomorphology, caused the tank model usefull only for concerning watershed. It is necessary to adjust some parameters of tank model for other watershed by recalibrating the parameters of the model. Rainfall runoff model using the tank model for a watershed scale is more reasonable focused on each sub-watershed by considering soil types, land use types and rainfall of the concerning watershed. Land use data can be enhanced by using landsat imagery or aerial photographs to support the validation the existing of land use type. Long term of observed discharges and rainfall data should be increased by set up the AWLR (Automatic Water Level Recorder) and rainfall stations for each of sub-watersheds. The reasonable tank model can be resulted not only by calibrating the parameters, but also by considering the observed and simulated infiltration for each soil and land use types of the concerning watershed. Key words: rainfall-runoff model, tank model, infiltration, land use types, soil types, watershed
Rousseau's Rome: Book IV of The Social Contract and the Specter of Montesquieu
Authors: Furnal Sara
Published: October 2023

Abstract: Scholars of Rousseau's Social Contract have focused primarily on the text's abstract principles of political right. This theoretical focus has come at the cost of serious consideration of practical aspects of Rousseau's thought, such as his views on bringing the political association into being and what Rousseau calls maxims of politics . One of his extended discussions about political practice occurs in Book IV of The Social Contract , yet this portion of the text largely has been ignored. My central claim is that Book IV merits serious attention since it changes Rousseau's project from one that uses political right merely to condemn institutions to a theory that uses right to identify latent possibilities for changing institutions. Further, this practical theory comes to light most clearly when one understands that he is in conversation with Montesquieu in Book IV on the topic of the Roman Republic.
A Skeleton of the Nation: Networks and Infrastructure in The Review
Authors: Buckley Jennifer
Published: October 2023

Abstract: This article argues that Daniel Defoe's tendency to write as a form of narrative cartographer predates his novels of the 1720s and owes much to his periodical writing in the early 1700s. Defoe's Review (1704–13) is an unusually peripatetic periodical, written while its author was travelling widely on the business of Robert Harley. Focusing on the periodical's early years (1704–5), this article explores how The Review acts as a repository for geospatial information. It uses correspondence and advertisements to consider how the periodical details the logistics of its publication and distribution, and how that distribution responds to changes in national infrastructure and politics.
New Louisa May Alcott Pieces: Radical Sensation in a Culture of Ambiguous Attribution
Authors: Chapnick Max L.
Published: October 2023

Abstract: This essay introduces a set of published but as-yet-unidentified Louisa May Alcott work including: pieces under Alcott's own name that are certainly Alcott's, pieces published anonymously or under known pseudonyms that are very likely Alcott's, and pieces published under a likely new pseudonym, I. or E. H. Gould, that are probably Alcott's. The uncertainty of authorship presented here aims to raise methodological and historicist questions about the author-function in a culture of ambiguous attribution: that writers in Alcott's time participated in author guessing-games and that today's scholarship could be more willing to engage the possibilities of not knowing. Focusing on the fiction, this essay argues that the new pieces from the 1850s produce a reassessment of Alcott's career: rather than her 1860s sensation fiction leading to the later domestic fiction, the sensation fiction of the 1860s itself emerges from years of earlier experimentation. As representative of the newly identified fiction, this essay introduces one short story under Alcott's own name and one short story under the Gould pseudonym.

Reconsidering shot noise in dual-comb spectroscopy
Authors: Walsh Mathieu , Genest Jérôme
Published: October 2023

Widening the detection bandwidth to acquire several spectral aliases unlocks a lower shot noise limit in dual-comb spectroscopy. This occurs while the power spectral density in all measurements respects the 2qI limit imposed by the semi-classical photodetection model, leading to the need to rethink the commonly accepted shot noise limit in Fourier transform spectroscopy.

Hybrid Differential Cavity Ring-down Spectroscopic Fiber Gas Sensing Instrument sensitivity-enhanced by Thermal Lens Effect
Authors: Yarai Atsushi
Published: October 2023

A new gas sensing technique based on a cavity ring down spectroscopy is proposed. This technique features the hybrid operation for enhancing the sensitivity by amplifying the optical absorption efficiency with a thermal lens (TL) effect. The limit of detection value is a few-fold higher values compared with our previous technique. It is confirmed that this hybrid operation boosted by TL effect functions with “mildly-hybrid”. Additionally, it points out that the structure of sensing head has significant function for assisting a hybrid operation.
