Authors: Xiao Wen , Chen Zonghui , Pan Feng , Hou Xueqin , Hao Hongliang , Guo Zhuang
Published: August 2021

A laser heterodyne imaging vibrometry is proposed for full-field vibration measurement. The vibration responses are imaged and recorded using a CMOS camera and a digital video recorder. A digital demodulation method based on a cumulative distribution function and autocorrelation is designed to demodulate signals affected by speckle noise. The experimental investigations confirm the viability of the proposed method for vibration measurement. Meanwhile, a comparison with laser Doppler vibrometry is performed to further validate the method. The results prove the proposed vibrometry is an effective and precise option for full-field vibration measurement.

Published: August 2021

Spatiotemporal mode locking is a nonlinear process of multimode soliton self-organization. Here the real-time buildup dynamics of the multiple solitons in a spatiotemporal mode-locked multimode fiber laser are investigated, assisted by the time-stretch technique. We find that the buildup processes are transverse mode dependent, especially during the stages of relaxation oscillation and

-switching prior to multiple soliton formation. Furthermore, we observe that the transverse modal composition of these generated pulses among the multiple solitons can be different from each other, indicating the spatiotemporal structure of the multiple soliton. A simplified theoretical model based on pulse energy evolution is put forward to interpret the role of 3D saturable absorber on spatiotemporal structures of spatiotemporal mode-locking multiple solitons. Our work has presented the spatiotemporal nonlinear dynamics in multimode fiber lasers, which are novel to those inside the single transverse mode fiber lasers.

Published: August 2021

Immune responses rely on a complex adaptive system in which the body and infections interact at multiple scales and in different compartments. We developed a modular model of CD4+ T cells, which uses four modeling approaches to integrate processes at three spatial scales in different tissues. In each cell, signal transduction and gene regulation are described by a logical model, metabolism by constraint-based models. Cell population dynamics are described by an agent-based model and systemic cytokine concentrations by ordinary differential equations. A Monte Carlo simulation algorithm allows information to flow efficiently between the four modules by separating the time scales. Such modularity improves computational performance and versatility and facilitates data integration. We validated our technology by reproducing known experimental results, including differentiation patterns of CD4+ T cells triggered by different combinations of cytokines, metabolic regulation by IL2 in these cells, and their response to influenza infection. In doing so, we added multi-scale insights to single-scale studies and demonstrated its predictive power by discovering switch-like and oscillatory behaviors of CD4+ T cells that arise from nonlinear dynamics interwoven across three scales. We identified the inflamed lymph node’s ability to retain naive CD4+ T cells as a key mechanism in generating these emergent behaviors. We envision our model and the generic framework encompassing it to serve as a tool for understanding cellular and molecular immunological problems through the lens of systems immunology.

Published: August 2021

Objective

Prisoners constitute a high-risk group for suicide, with suicide rates about 5 to 8 times higher than in the general population. The first weeks of imprisonment are a particularly vulnerable time, but there is limited knowledge about the risk factors for either early or late suicide events.

Methods

Based on a national total sample of prison suicides in Germany between 2005 and 2017, suicides within the first 2 (4 and 8) weeks after reception into prison were matched by age and penalty length with cases that occurred later. Factors that potentially influence the timing of suicide were investigated.

Results

The study has shown that 16.7% (31.5%) of all 390 suicides in German prisons occurred within the first two weeks (two months) of imprisonment. Factors that facilitate adaptation to the prison environment (e.g. prior prison experience) were negatively associated with early suicide events. Factors that hindered the adaptation process (e.g. withdrawal from illicit drugs) were observed more frequently in early suicide events than in late ones. These factors are active at different times of imprisonment.

Conclusion

At reception, particular attention should be paid to the following factors associated with early suicide events: widowed marital status, lack of prison experience, and drug dependency.
Temporal deposition of copper and zinc in the sediments of metal removal constructed wetlands
Authors: Elhaj Baddar Zeinah , Peck Erin , Xu Xiaoyu
Published: August 2021

The objective of this study was to explore the effects of time, seasons, and total carbon (TC) on Copper (Cu) and Zinc (Zn) deposition in the surface sediments. This study was performed at the H-02 constructed wetland on the Savannah River Site (Aiken, SC, USA). Covering both warm (April-September) and cool (October-March) seasons, several sediment cores were collected twice a year from the H-02 constructed wetland cells from 2007 to 2013. Total concentrations of Cu and Zn were measured in the sediments. Concentrations of Cu and Zn (mean ± standard deviation) in the surface sediments over 7 years of operation increased from 6.0 ± 2.8 and 14.6 ± 4.5 mg kg-1 to 139.6 ± 87.7 and 279.3 ± 202.9 mg kg-1 dry weight, respectively. The linear regression model explained the behavior and the variability of Cu deposition in the sediments. On the other hand, using the generalized least squares extension with the linear regression model allowed for unequal variance and thus produced a model that explained the variance properly, and as a result, was more successful in explaining the pattern of Zn deposition. Total carbon significantly affected both Cu (p = 0.047) and Zn (p < 0.001). Time effect on Cu deposition was statistically significant (p = 0.013), whereas Zn was significantly affected by the season (p = 0.009).

Authors: Huang Xilang , Lee Sang Joon , Kim Chang Zoo , Choi Seon Han
Published: August 2021

Purpose

This study aims to provide an automatic strabismus screening method for people who live in remote areas with poor medical accessibility.

Materials and methods

The proposed method first utilizes a pretrained convolutional neural network-based face-detection model and a detector for 68 facial landmarks to extract the eye region for a frontal facial image. Second, Otsu’s binarization and the HSV color model are applied to the image to eliminate the influence of eyelashes and canthi. Then, the method samples all of the pixel points on the limbus and applies the least square method to obtain the coordinate of the pupil center. Lastly, we calculated the distances from the pupil center to the medial and lateral canthus to measure the deviation of the positional similarity of two eyes for strabismus screening.

Result

We used a total of 60 frontal facial images (30 strabismus images, 30 normal images) to validate the proposed method. The average value of the iris positional similarity of normal images was smaller than one of the strabismus images via the method (p-value<0.001). The sample mean and sample standard deviation of the positional similarity of the normal and strabismus images were 1.073 ± 0.014 and 0.039, as well as 1.924 ± 0.169 and 0.472, respectively.

Conclusion

The experimental results of 60 images show that the proposed method is a promising automatic strabismus screening method for people living in remote areas with poor medical accessibility.
Organic entities, costume, human body and neo-liberalism
Authors: Kolenik Tina
Published: August 2021

This visual essay presents four of the author’s artistic projects, which respond to prevailing eastern European neo-liberal conceptions of the human body and the subjects it produces. The first project is concerned with the use of human skin as an organic material donated by its ‘owner’ for the manufacture of a corset and belt, which become parts of a new costume. The second project explores the characteristic of the ‘ideal’ neo-liberal human subject by means of the costume produced by manipulating the author’s own blood. The third project highlights the cultural norm according to which one is expected to present oneself to the known and especially unknown others in line with the dominant standards of feminine beauty – erotically attractive, healthy, youthful and slim. The fourth project focuses on the almost obsessive endeavour to preserve or rather achieve ‘the perfect skin’, as evident in countless beauty advertisements and artificially ‘optimized’ selfies.

Authors: Jung Chang Shin , Jung Youn Joo , Kim Dong Il , Lee Seungju , Kang Seok Kyung , Nam Su Bong , Kim Hyun Yul
Published: August 2021

Purpose: The purpose of this study was to compare the clinical characteristics and outcomes of hormone receptor-positive (HR+) human epidermal growth factor 2-negative (HER2–) breast cancer among elderly patients (over 65 years old) and younger patients.Methods: This was a retrospective cohort study of 328 patients who were treated for breast cancer at Pusan National University Yangsan Hospital between January 2009 and December 2014. Tumor characteristics, surgical methods, and survival outcomes were compared between the two age groups (<65 and ≥65 years old). Kaplan-Meier curves for disease-free survival (DFS) and overall survival (OS) were also constructed according to the age groups.Results: Among the 328 patients with HR+ HER2– breast cancer, 184 (56.1%) were <65 years old and 144 (43.9%) were ≥65 years old. Breast cancer stages were similar between the two age groups, but the older patients were treated less often with chemotherapy (81% vs. 66%, P=0.002). During the follow-up period, 17 deaths and 36 cases of recurrence or metastasis were reported. There was no difference in DFS between the two groups (P=0.840); however, the OS of the older age group was significantly lower than that of the younger age group (P=0.015).Conclusion: This study suggested that HR+ HER2– breast cancer patients belonging to the two age groups had no significant difference in DFS. However, older age is an independent factor affecting OS rate. Therefore, even if patients are old, but their physical condition is satisfactory, standard and active treatment may be necessary, similar to that given to younger patients.

Published: August 2021

Purpose: Adjuvant chemotherapy is recommended after curative surgery in patients with colon cancer of high-risk stage II and stage III. However, a considerable number of patients cannot complete the scheduled adjuvant treatment for various reasons. This study investigates the hindering factors to the adherence to adjuvant chemotherapy and their impact on long-term survival.Methods: A retrospective study was conducted for patients with colon cancer and had curative resection from 2009 to 2014. Among patients with pathologic stage II and III, stage II with low-risk features, double primary cancers, R2 resection cases were excluded. Patients were grouped into three groups: no-adjuvant therapy, adjuvant therapy for less than 3 months, and more than 3 months. Factors for withdrawal and the oncologic outcome were analyzed.Results: Of 571 patients, adjuvant chemotherapy was recommended in 403. One hundred and sixteen patients (28.8%) did not receive adjuvant chemotherapy, 78 (19.4%) withdrew within 3 months, and 209 (51.9%) maintained for more than 3 months. Factors for not receiving adjuvant chemotherapy or withdrawing within 3 months were older than 70 and American Society of Anesthesiologists class 3 or higher. Main reasons for discontinuation before 3 months were chemotoxicity and patient’s refusal. The long-term oncologic outcome of the patients who received adjuvant chemotherapy for more than 3 months was significantly better than others.Conclusion: No-adjuvant therapy or receiving them for lesser than 3 months is significantly affected by the patient’s performance status and social support, which coincides with a poor oncologic outcome. Social support and rehabilitation system may help to improve the survival outcome.

Purpose: This study aimed to investigate the clinical outcomes after totally implantable access port (TIAP) implantation performed by general surgery residents in patients with colorectal cancer.Methods: A total of 291 consecutive patients who underwent TIAP implantations were evaluated. The patients were divided into threegroups: second-, third-, and fourth-grade residents.Results: The mean follow-up was 22.1 months (range, 1–87 months). The total times of operation, puncture, and cannulation decreased as the resident grade increased (P<0.001). Early complications significantly decreased with higher resident grades (P=0.039). The non-use of ultrasonography and non-use of C-arm were identified as independent risk factors for complications. Resident grades between second and third (P=0.005) and between second and fourth (P=0.041) were identified as independent risk factors for optimal tip position.Conclusion: TIAP implantation can be safely and effectively performed by residents. Low-grade residents were associated with early complications.
Factors related to compliance with adjuvant chemotherapy in patients with gastric cancer: A retrospective single-center study
Authors: Jin Geon Yi , Park Ki Bum , Song Kyo Young
Published: August 2021

Purpose: Adjuvant chemotherapy (AC) improves survival outcomes in patients with advanced gastric cancer (GC) after curative surgery; however, some patients do not receive or complete chemotherapy. This study aimed to identify factors related to patient compliance with chemotherapy after curative surgery for advanced GC.Methods: The data of patients who underwent curative gastrectomy for pathologic stage II–III GC between 2012 and 2016 were reviewed. Patients were divided into an AC completion group (group C), AC incompletion group (group I), and surgery-only group (group S). The AC regimen was either tegafur/gimeracil/oteracil (S-1) or capecitabine plus oxaliplatin (XELOX).Results: The study enrolled 417 patients; group C had 222 patients, group I had 110, and group S had 85. The most common reason for not initiating AC was poor general condition (36.5%), while chemotherapy-related complications was the common reason for AC incompletion (43.6%). In multivariate analysis, age over 65 years, Eastern Cooperative Oncology Group performance status ≥1, Charlson comorbidity index ≥1, and the presence of postoperative complications were independent risk factors for not initiating AC (odds ratio: 4.32, 2.62, 1.84, and 2.17, respectively). Age over 65 years, longer postoperative stay, and XELOX regimen were significant risk factors for incompletion of AC (odds ratio: 2.68, 1.72, and 2.23, respectively).Conclusion: Old age, poor performance status, comorbidities, and postoperative complications, longer postoperative hospital stay, and XELOX regimen were associated with poor compliance with AC in GC patients. Clinicians can improve compliance with AC by managing postoperative complications and selecting the most appropriate treatment regimen.

Authors: Jeong Jin Woon , Noh Ji Hyun , Kang Jeong Hyun , Park Ji Hyun , Lee Joo Hyung
Published: August 2021

Malakoplakia is a rare chronic granulomatous disease found in the genitourinary tract, mainly. It is considered to be related to immunosuppression and/or infectious processes. We would like to present an operative case of cecal malakoplakia in a patient with a history of surgical resection and chemotherapy for cervical cancer. A 74-year-old female patient visited our hospital for 1-year follow-up after operation and chemo-radiotherapy for cervical cancer. An infiltrative mass of 6 cm, between the cecal base and the right psoas muscle, was observed on computed tomography. An ileocectomy was performed for diagnosis. Histopathologic examination revealed cecal malakoplakia. After surgery, based on previous reports, antibiotics therapy was added. Then the patient was discharged and treated in the outpatient clinic. To our knowledge, a rare case has been described of cecal malakoplakia during observation after surgery and chemo-radiotherapy for cervical cancer. Malakoplakia is known to be related to immunosuppressive condition. Therefore, our case suggests that close observation should be made in patients on immunosuppressive condition, such as chemotherapy.
Rare case of postoperative mediastinitis following thyroidectomy
Authors: Cho In Soo , Lee Moo Hyun , Cho Jihyoung
Published: August 2021

Descending necrotizing mediastinitis (DNM) is a life-threatening complication secondary to oropharyngeal abscesses, cervical esophageal perforation, or neck infections spreading along the fascial planes into the mediastinum. Post-thyroidectomy surgical site infection is a highly unusual complication that is typically localized around the incision, but may be propagated into the mediastinum, causing DNM. We encountered a case of this rare complication after thyroidectomy. The patient was a 33-year-old woman who was admitted to our center for left hemithyroidectomy. The surgery was performed without any intraoperative events. However, she later developed fever, hypotension, and tachycardia. Imaging revealed deep neck emphysema and focal pneumomediastinum with infiltration in the anterior neck and mediastinum with abscess formation. Additional imaging at 7 days postoperatively revealed reduced fluid collection deep in the neck with minimal changes in fluid collection in the mediastinum. Esophageal perforation was excluded via an esophagogram, which lead to the conclusion that the infection may have been caused by open thyroidectomy. The patient was treated with prompt medical and surgical intervention. After treatment, she was discharged from the hospital with no further complications. We present our case report as well as a literature review of the diagnosis and treatment of this disease.

Objetivo: Verificar que la estructura factorial de los datos observados estén en correspondencia con la estructura factorial teórica de la empatía. Estimar y comparar los niveles de empatía en las especialidades médicas evaluadas. Materiales y métodos: Estudio realizado en el cantón de Cuenca (Ecuador) en 2019. Diseño descriptivo y transversal. La muestra estuvo constituida por 223 médicos que trabajaban en el sector público, quienes respondieron voluntariamente la Escala de Empatía Médica de Jefferson. Variables dependientes: niveles de empatía y sus dimensiones. Independientes: género, nivel de atención y especialidad. Se estimó la normalidad y homocedasticidad, Análisis Factorial Confirmatorio, Invarianza entre grupos, análisis de varianza trifactorial y de un factor, t-Student y d de Cohen. El nivel de significación fue α≤ .05. Resultados: Se observa una adecuada consistencia interna, se confirma el modelo de tres dimensiones del instrumento original. No existen diferencias entre los géneros (p> .05), pero sí entre los tipos de atención y entre las especialidades (p< .05). Los datos observados tienen la estructura factorial teórica asociada al instrumento empleado en la medición de la empatía. Conclusión: El análisis multigrupo permite asumir invarianza factorial de la empatía entre los géneros, sin que se logre especificar un modelo según tipos de atención al paciente. Los niveles de empatía global fueron mayores en la atención primaria en relación con la hospitalaria y mayor en las especialidades de Pediatría y Medicina Familiar (unidas).

Authors: Reynaldos-Grandón Katiuska , Pedrero Víctor
Published: August 2021

Introducción: Se ha descrito que los profesionales de enfermería son particularmente proclives a desarrollar burnout, especialmente aquellos que se desempeñan en unidades con una alta demanda física y psicológica. Diversos estudios han mostrado que la técnica de mindfulness o atención plena (MBI) como un recurso útil para la reducción de burnout en profesionales sanitarios, entendiendo este como simplemente parar y estar presente, sin juicios mentales. Este estudio pretende evaluar el impacto inicial de una intervención basa-da en esta técnica. Métodos: Estudio exploratorio pre- y post- intervención (n=34 enfermeros). Se implementó una intervención para reducir el estrés basada en atención plena (MBSR) de 8 sesiones según lo propuesto por Shapiro y Carlson. Se midió burnout y nivel de Atención Plena. Para evaluar las diferencias en los niveles de Atención Plena y burnout se utilizó prueba t para muestras relacionadas. Finalmente se analizó la correlación entre la asistencia a las sesiones y el cambio en los niveles de burnout y mindfulness de los participantes. Resultados: El nivel de atención plena se incrementó en promedio 12,62 puntos (p<0.001). No se observó diferencia en el nivel global de burnout. Sin embargo, existieron variaciones en el nivel de culpa e indolencia, los cuales disminuyeron significativamente posterior a la intervención. Además se apreció una correlación positiva entre el porcentaje de asistencia y el cambio en el nivel de atención plena de los participantes. Conclusión: Este estudio muestra un efecto beneficioso de una intervención basada en atención plena tanto en el aprendizaje de la técnica como en la reducción de algunas facetas del burnout en profesionales de enfermería.

Teologiczna interpretacja pojęcia arché u wczesnych fi lozofów greckich: w kręgu teologii milezyjskich fi lozofów przyrody
Authors: Picewicz Joanna
Published: August 2021

The purpose of this article is an attempt to present one fundamental problem: identifi cation of the essential features of the arché in Milesian philosophers of nature by indicating possible relationships with theology. The theological interpretation of the Milesians indicates that arché does not merely have a material dimension, it is inherently external, going beyond, and consequently, the original principle contains a peculiar transcendence. In the concepts of natural philosophers, there is an archaic path to immortality, infi nity, and eternal existence, which are, in essence, divine attributes. There is a clear search to determine the relationship of divine sphere of existence with the world that we know from everyday experience. This means that the Milesians have found a plane on which the divine sphere and the temporal sphere can meet. There are certain frameworks within which there is an interaction between the divine element (constant and invariant) and temporal (transient and fi nite).
The tongues of stones: diversity of interlocutions in Arabic alchemical writings
Authors: Ziegler Vicky
Published: August 2021

Dialogues and interlocutions in Arabic alchemical writings have already attracted the attention of several researchers. These previous studies mainly focused on dialogues composed in the classical form of alchemical writings, which are interlocutions between a master of alchemy and his disciple. The teaching dialogue between Zosimos and his disciple Theosebeia in the Muṣḥaf al-ṣuwar (“The Book of Pictures”) can be regarded as one of the most influential examples. This paper focuses instead on the diversity of interlocutions that appear in alchemical writings with regard to their literary construction as well as their characters and what they represent. For this research, extracts from different alchemical writings will serve as examples: Mufākharat al-aḥjār (“The Boasting of Stones”) and an excerpt from Kitāb al-Rawḍa (“The Book of the Garden”), both attributed in the manuscripts to the Andalusian mathematician Maslama al-Majrīṭī, in addition to an excerpt from Kitāb al-Aqālīm al-sabʿa (“The Book of the Seven Climes”) ascribed to al-Sīmāwī, and a poem of seventy verses – al-Qaṣīda al-sabʿīniyya – by an unknown author. This paper aims to explore how Arabic-writing alchemists made use of a versatile repertoire of literary and didactic methods to transfer their knowledge of alchemy to the subsequent generations.
Inexact Inverse Subspace Iteration with Preconditioning Applied to Quadratic Matrix Polynomials
Authors: Sadkane Miloud
Published: August 2021

An inexact variant of inverse subspace iteration is used to find a small invariant pair of a large quadratic matrix polynomial.
It is shown that linear convergence is preserved provided the inner iteration is performed with increasing accuracy.
A preconditioned block GMRES solver is employed as inner iteration.
The preconditioner uses the strategy of “tuning” which prevents the inner iteration from increasing and therefore results in a substantial saving in costs.
The accuracy of the computed invariant pair can be improved by the addition of a post-processing step involving very few iterations of Newton’s method.
The effectiveness of the proposed approach is demonstrated by numerical experiments.
Relating adolescents’ exposure to legacy and digital news media and intergroup contact to their attitudes towards immigrants
Authors: Vissenberg Joyce , Coninck David De , d’Haenens Leen
Published: August 2021

Previous research has found that news coverage on immigration is often biased in negative ways and that it inspires the formation of negative attitudes towards immigrants. However, academic research about this link between news consumption and attitudes towards immigrants among adolescents remains limited. The current study aims to test this association from a media-exposure and intergroup-contact perspective using survey data from 875 adolescents in Flanders, Belgium. The findings show that only television news consumption, thus no other types of news consumption, was associated with adolescents’ attitudes towards immigrants. Intergroup contact within the friend group, outside the school context, was linked to more positive attitudes. This study nuances earlier findings that news consumption predicts attitudes towards immigrants. Implications for future research are discussed.

In this paper a review on different signal generation techniques for Radio over Fiber systems is presented. Radio over fiber has become a conspicuous contender in upcoming high data rate demands from household and enterprises users. Radio signals or waves can be generated back from optical signals at RAU (radio access unit) so that they may be transmitted to mobile stations. This generation is first assembled into different categories on the basis of some similar parameters, various aspects of each category are given and then a comparison between different aspect of each technique is summarized in table. Analysis of these techniques on the basis of ranges of radio frequencies that can be generated is also proposed in this paper.

In this paper, we use a simple and cheap approach for the synthesis of herceptin-conjugated graphene biosensor to detect the HER2-positive breast cancer cells. The bifunctional graphene-herceptin nanosheets are prepared from graphite by a simple ultrasonic-mediated technique. The prepared protein-mediated graphene is fully characterized. The results show the exfoliation of graphene layers in herceptin solution. Moreover, herceptin is effectively conjugated into the surface of graphene nanosheets. The synthesized herceptin-conjugated graphene is applied for breast cancer detection. The linear range of this biosensor is 1–80 cells, which is significant. The biosensor shows an excellent selectivity performance for detection of HER2-positive cancer cells. Likewise, the stability and functionality of the biosensor is about 40 days. Based on the results, this device is a promising candidate for rapid and selective detection of cancer cells.
The Authority of the Bible and the Church Fathers in Adolf von Harnack’s Thought
Authors: Dessy Valeria
Published: August 2021

This article begins with an analysis of Adolf von Harnack’s research on biblical and patristic sources in regard to the development of the authoritative church. I provide a close textual analysis of Harnack’s The Origin of the New Testament and the Most Important Consequences of the New Creation (1914). This analysis shows that Harnack regarded biblical and patristic sources as extremely meaningful, as they provide a trustworthy account of the origins of Christianity, but they were also open to critical analysis. I continue this investigation with a close textual reading of Harnack’s correspondence with Karl Barth from 1923, in which the two theologians discussed, among other topics, the possibility of talking about God. I argue that we should place Harnack’s analysis of the biblical and patristic sources within a broader epistemological reflection on the possibilities of human knowledge, to which Harnack dedicated a great deal of attention, even if he did not develop it systematically in his vast literary production.
Whose Story? Which Sacrifice? On the Story of Jephthah’s Daughter
Authors: Koci Katerina
Published: August 2021

The story of Jephthah and his daughter (Judg. 11:29–40) is a peculiar and problematic text. This article explores the question of the accountability for the sacrificial act with which the story culminates, and which provokes sharp disapproval in certain quarters, especially because of its gender bias. Applying the hermeneutical framework of René Girard and his distinction between sacrifice in Greek mythology (divinity in charge) and sacrifice in Judeo-Christian revelation (everyone responsible for his/her actions), I investigate the question: Is Jephthah’s daughter a mute puppet in a drama staged by her tyrannical father, or perhaps fate, or is she rather a woman who is responsible for her own actions and accountable only to herself? The answer is twofold: she is a woman fully responsible for herself; however, the responsibility for her premature and violent death is shared by her father, herself, and the biblical author–redactor. After identifying Jephthah’s daughter as a person responsible for her own actions, I aim to overcome the dialectic of “the text of terror” (post-structuralist interpretation) and the search for “herstory” (neoliberal interpretation). I suggest that in her powerlessness against patriarchal tyranny, Jephthah’s daughter nonetheless exerts power and authority in condemning the existing power structures. Without approving any form of sacrifice, reading the story through a lens of powerful powerlessness can help us discern different forms of power and, ultimately, reject the aggression and violence that has dominated our world to this very day.
Considering Victims' Minds in the Evaluation of Harmful Agents' Moral Standing
Authors: Akechi Hironori , Hietanen Jari K.
Published: August 2021

An agent's moral standing is considered as depending on the agent's mind and their harmfulness toward a victim, but a victim's mind and species may also matter. To examine whether a victim's species (i.e., human or another) and a victim's mind are considered in the judgment of a harmful agent's moral standing, the present study modulated the mental capacities of an imaginary species. Only humans' suffering was considered when the other species' mental capacities were presumed to be low (Study 1), but humans' and the other species' suffering were equally considered when the other species had mental capacities that were presumed to be equivalent to those of humans (Study 2). The results suggest that our judgments of the moral standing of an agent 1) depend not only on the agent's mind but also on the victim's mind and 2) are not human species-oriented but human mind-oriented.
Influence of layer arrangement on bonding and bending performances of cross-laminated timber using two different species
Authors: Kim Keon-Ho
Published: August 2021

Cross-laminated timber (CLT) is a wood panel product that can be arranged in different ways. The advantage of utilizing CLT is the ability to use lamination even with low density materials or those that have defects, like knots. This study evaluated the bonding and bending performances of CLT utilizing domestic species in a shear wall or floor via a face bonding test of layers and a three-point bending test. The tests were carried out with three-layered CLT made up of Japanese larch and/or Korean red pine in various configurations. The layer arrangement for lamination was divided according to the species and grade of the wood. The out-of-plane and in-plane bending tests were conducted on the CLT according to the applicable direction in a wooden structure. The results of the bonding test showed that the block shear strength and delamination of all types of CLT met the BS EN 16351 (2015) standard requirements. The results of the bending test based on two wood species showed that the bending strength of the larch CLT was higher than that of the pine CLT in single species combinations. For mixed species combinations, the bending properties of CLT using larch as the major layer was higher than those using pine as the major layer. This demonstrated that the major layer had more influence on the bending properties of CLT and that Korean red pine was more suited for the minor layer of CLT.
Effects of bamboo species, steam-heating treatment, and adhesives on mechanical properties and dimensional stability of oriented bamboo scrimber boards
Authors: Lee Chia-Ju , Chung Min-Jay
Published: August 2021

Effects of bamboo species, adhesives, and steam-heating treatment (SHT) were examined relative to mechanical properties and dimensional stability of oriented bamboo scrimber board (OBSB) made from makino bamboo (Phyllostachys makinoi Hayata) and moso bamboo (P. pubescens (Mazel)) strips. Results indicated that OBSB produced using makino bamboo culms bonded with water-soluble phenol formaldehyde resin (PF) had significantly higher ultrasonic wave velocity (Vu (//)), tap tone sound velocity (Vt (//)), dynamic modulus of elasticity (DMOEu (//)), and DMOEt (//) than that produced using moso bamboo bonded with water-soluble urea formaldehyde resin (UF) (p < 0.05). The two types of OBSB showed the same trend of DMOEu > DMOEt > modulus of elasticity (MOE). In addition, OBSB made using steam-heated makino bamboo and PF had the largest modulus of rupture (MOR) (210.5 MPa), exceeding that of OBSB made using laminated bamboo timber and wood-plastic composite (WPC). However, OBSB made using steam-heated moso bamboo and UF exhibited the highest screw holding strength (SHS). Improvement in dimensional stability was observed in OBSB manufactured using steam-heated culms. Finally, OBSB glued with UF had lower water absorption, thickness swelling, and volumetric swelling than that glued with PF.

Estimates of objective function minimum for solving linear fractional unconstrained combinatorial optimization problems on arrangements
Authors: Barbolina Tetiana
Published: August 2021

The paper is devoted to the study of one class of Euclidean combinatorial optimization problems — combinatorial optimization problems on the general set of arrangements with linear fractional objective function and without additional (non-combinatorial) constraints. The paper substantiates the improvement of the polynomial algorithm for solving the specified class of problems. This algorithm foresees solving a finite sequence of linear unconstrained problems of combinatorial optimization on arrangements. The modification of the algorithm is based on the use of estimates of the objective function on the feasible set. This allows to exclude some of the problems from consideration and reduce the number of problems to be solved. The numerical experiments confirm the practical efficiency of the proposed approach.
