Authors: LEE Mi-Aie , KIM Ik-Jung , HONG Sung-Hoon
Published: July 2023

We evaluated the moral judgment of nursing student using DIT test. The mean p value of the students was 45.68(±13.65). And there was no p value difference between student group divided by demographical parameters such as gender, grade, age, family size, sibling and family income. The only parameter which showed difference was religion. Catholic students showed lower p value but this result could not be generalized because the group size of Catholic students were very small. The fact that grade showed no difference means that the curriculum of this school had no effect on students’ whole person education. In conclusion, nursing school need to improve the curriculum to develop students’personalities which is needed in future nurse’s ability.
How Should Scarce Healthcare Resources be Rationed during the COVID-19 Pandemic?
Authors: Lee Kyungdo
Published: July 2023

Experts have been warning of a second wave of COVID-19 infections that is expected to occur within the next two months. If this prediction comes true, the demand for ventilators, intensive care units, and other healthcare resources may be greater than the supply, raising questions of distributive justice and the rationing of scarce healthcare resources. This article summarizes some of the theoretical issues associated with distributive justice, examines the ethical basis of the rationing principles that have been adopted by certain hospitals in the United States, and attempts to identify common ground that might facilitate broad agreement concerning the principles that should guide resource-allocation decisions during this pandemic. The article aims to show, firstly, that from the perspective of a non-utilitarian, rights-based theory, it is fair or just to allocate lifesaving resources in ways that save the greatest number of lives. Nevertheless, it is also argued that there are several other factors need to be considered in the rationing of healthcare resources, including a patient’s age, disability status, health condition, occupation, time of admission to a health care facility, and whether the patient’s disease is COVID-19.
Two Conflicting Aspects of Digital Health Technology: Public Safety and Individual Rights*
Authors: KIM Do-Kyong
Published: July 2023

It is widely thought that digital health technology will promote more informed decision-making and thereby improve patients’ health. Additionally, this technology is expected to enhance the quality, accessibility, and efficiency of the public healthcare system and strengthen national industrial competitiveness. However, the widespread use of digital health technology may also have certain negative effects on medical practice and raise ethical concerns. This article illuminates some of the hidden problems and concerns with this technology. First, in distinguishing between normal and abnormal conditions, this technology may end up judging and excessively controlling the characteristics and lifestyles of individuals. Second, the collection and use of big data, upon which digital health technology is based, threatens individual privacy and autonomy. During the COVID-19 pandemic, digital health technology has been used to monitor the quarantine compliance of infected individuals, trace contacts, model the spread of the virus, and provide telemedicine to COVID-19 patients. However, this ability to identify, monitor, and trace individuals has led to invasions of privacy and social discrimination.
The Need for Ethics and Communication between Social Sectors Due to Disruptions in the Human-Animal-Environment Interface*
Authors: CHOI Eunjoo
Published: July 2023

This paper examines the concept of “One Health,” which was established in 2000 by international organizations to prevent the global spread of infectious diseases due to disruptions in the human-animal-environment interface. Although One Health regards the health of humans, animals, and the environment as inextricably linked, there are in fact many causal factors that contribute to the spread of infectious diseases like COVID-19. This article identifies one causal factor with the “closure” by system differentiation of modern society. All sectors of society have become specialized, and perform their unique functions with exclusivity. As all sectors have their own expertise, irreplaceability has been normalized, and multidisciplinary and multi-organizational cooperation has become difficult. One Health is possible only if it transcends this system closure. However, despite national and international efforts, cooperation remains difficult to achieve because of the closed systems of communication within these different government agencies and sectors of the economy. What is needed is recognition of the fact that the human-animal-environment interface is a single unit and, therefore, that individual organizations, government agencies, or even fields of research cannot solve these complex problems on their own.
Social System and One Health Communication: Why is It So Difficult for Society to Perceive Environmental Dangers?*
Authors: CHOI Eunjoo
Published: July 2023

This article considers the question of why it is difficult to adopt a One Health approach to optimizing health despite its importance and argues that ecological thinking is necessary for the practice of One Health. Although from an environmental perspective humans and non-humans co-exist in a complex set of relationships, social systems tend to treat humans, animals, and the environment as distinct entities. Accordingly, Niklas Luhmann attributes ecological problems, at least in part, to society itself and not merely to political or economic failures or moral shortcomings. However, while social systems such as the economy, science, politics, and education, are in an important sense closed, they can also be responsive to each other through One Health communication. Above all, in order for One Health to operate within these social systems there is a social need for ecological thinking that the human body is inseparable from the material world, biological life, ecosystems, biomaterials, and human-made materials.
The Right to Die without Pain: A Discussion on Euthanasia in
France*
Authors: JOE Tegu
Published: July 2023

In France, public debates and discussions concerning euthanasia began over 20
years with the introduction of palliative care and acceptance of a patient’s
right to discontinue life-sustaining treatment. More recent legislation in
France allows deep and continuous sedation until death for terminally ill
patients who are in extreme pain. The trend in France has been a trend toward
greater access to palliative care and a more expansive set of rights and
freedoms for patients approaching the end of life. This article summarizes the
recent history of French legislation concerning euthanasia and argues that
guiding objective in these legislative changes has been formal recognition, not
of a patient’s right to die, but of a patient’s right to die without pain. In
the conflict between the right to die and the right to life, the French have
prioritized the former because what they desire, above all else, is the right to
avoid suffering.

Published: July 2023

Understanding cultural diversity can bridge cultural differences between teachers and students from various ethnicities and cultures. Students from diverse ethnic and cultures will get benefit from teaching strategies that are responsive to diverse cultures. In an effort to understand cultural diversity in Malaysia, one of the ways is the need to have cultural skills among preservice teachers. Preservice teachers need to have a high level of cultural skills so that every teaching and learning session in the class can attract students' interest and avoid bias, that can make teaching sessions in the classroom more effective and responsive to cultural diversity. Teacher education programs need to provide more opportunities for preservice teachers to engage and interact with diverse cultures in order to improve the cultural skills of preservice teachers to teach students from diverse ethnic and cultures and can improve the teaching quality of preservice teachers when teaching in the diverse classroom.

This study intends at pinpointing factors that contribute to setbacks in building projects in the UAE. For that purpose, a designed questionnaire study was supplied to professional engineers in the UAE construction industry. A literature analysis was also performed, in which 106 elements were discovered. The discoveries suggested that the leading postponement risk reasons are as follows: variations of orders; interruptions in decision-making and endorsement bycustomers ; contractors’ funding problems; inadequate site administration and control by contractors; and inadequate management of project development. These conclusions can aid the construction industry by providing enhancements to the guidelines to encounter market requirements; guiding proprietors in decision making and dropping change order appeals; supporting contractors in preparation; handling the project and risks (internal or external) when assessing and organizing; and assisting professionals to utilize project management methods through construction, permitting adequate time to construct and organize the building records.
Effect of Ovality on the Buckling Behavior of Thin-Walled Liquid-Filled Conical Tanks
Authors:   Department of Civil Engineering, Aksum University, Aksum, Ethiopia,, Azanaw Girmay Mengesha
Published: July 2023

This study investigates the influence of ovality on the buckling behavior of thin-walled liquid-filled conical tanks through comprehensive numerical simulations. The structural stability of conical tanks is of paramount importance in various engineering applications, such as storage vessels and aerospace structures. However, the presence of ovality, characterized by deviations from perfect circularity, can significantly affect the structural response and integrity of these tanks. To explore the effects of ovality, a finite element analysis (FEA) approach is employed, considering various ovality levels in the tank geometry. A comprehensive parametric study is conducted, varying key parameters such as tank dimensions, material properties, and liquid filling levels. The buckling behavior of the tanks is assessed by examining critical buckling loads and corresponding deformation modes. Results from the numerical simulations reveal that even small levels of ovality can substantially reduce the buckling load capacity of conical tanks. As ovality increases, the onset of buckling occurs at lower applied loads, leading to premature structural failure. The presence of liquid filling further exacerbates the buckling phenomenon, with the liquid sloshing effect amplifying the structural response. The study also investigates the influence of different materials on the buckling behavior of conical tanks subjected to ovality. It is found that the material stiffness and yield strength play a crucial role in determining the critical buckling load and mode shape. Furthermore, the effect of liquid fill level is explored, demonstrating that higher fill levels increase the vulnerability to buckling.

Many link prediction methods have been put out and tested on several actual networks. The weights of linkages are rarely considered in these studies. Taking both the network's structure and link weight into account is required for link prediction. Previous researchers mostly overlooked the topological structure data in favour of the naturally occurring link weight. With the use of the concept of entropy, a new link prediction algorithm has been put forth in this paper.When used in real-time social networks, this algorithm outperforms the industry standard techniques. This paper concentrated on both topological structural information which focuses on calculating the vertex entropy of each very vertex and link weight in the proposed method. Both weighted and unweighted networks can benefit from the proposed method. Unipartite and bipartite networks can also use the suggested methods. Further, results demonstrate that the proposed method performs better than competing or traditional strategies, particularly when targeted social networks are sufficiently dense.

Published: July 2023

Most non-destructive tests of concrete require sophis-ticated equipment and training; in this work we aim to develop a simple method to estimate the strength class of cylindrical con-crete samples based on vibrations signals that are collected after striking a concrete cylinder with a hammer. The vibration signals were collected by attaching a smartphone to the concrete cylinder and logging the vibrations registered via the smartphone’s built-in accelerometer. The acquired 1-D vibration signals are trans-formed to 2-D scalograms using continuous wavelet transform. Scalograms are then used to train a deep learning model to predict the strength class. Preliminary findings show that the model is capable of classifying the strength of concrete to low, high, or me-dium. The developed model achieved a high accuracy of 91.67%. The promising results of this work shed light into the future of smartphone-based measurements of construction materials’ properties.

The primary means of mobility today are vehicles. For better braking system better materials are provided for tribo pairs. To reduce the cost of the tribo pairs instead of metals, composite materials are used recent days. This topic deals with the combination of brake disc and brake pad which is generally called tribo pair. As a consequence of its distinctive qualities like high fatigue strength, high hardness, high strength, high specific modulus, light weight and low density, the use of Al-SiC Metal Matrix Composites for brake disc & pad have been steadily expanding in recent years. The properties of the metal matrix composite like tensile and compression strength, as well as hardness, are investigated in order to identify the optimal carbide percent. For brake pad different material compositions are mixed together and in powder metallurgy method brake pad fabrication is developed. Previously Asbestos is commonly employ as a material for brake pads in automobiles. Brake pads are subjected to a great deal of friction, which generates a great deal of heat. Asbestos is a better heat absorber and dissipater than other materials. The main downside of asbestos is that it is extremely harmful to human's health. That’s why asbestos can be replaced by other materials. This paper mainly covers recent advancement of composite brake friction materials along with comparison of every component with proper validation.

Kanker tiroid merupakan kanker paling umum pada sistem endokrin. Dalam pendeteksian kanker tiroid, pemeriksaan standar emasnya adalah menggunakan fine-needle aspiration (FNA), dimana hasil sitologinya digunakan pada 60% - 80% kasus. Pemeriksaan FNA dilakukan secara preoperatif untuk menentukan manajemen inisial dari kanker tiroid. Namun, teknik FNA dibatasi oleh sampel yang tidak mencukupi pada sekitar 2% - 20% kasus dan sekitar 10% - 30% hasil dari FNA diklasifikasikan sebagai indeterminate (ITN) pada sistem Bethesda. Karena itu, uji molekular seperti pemeriksaan biomarker BRAF diharapkan dapat membantu meningkatkan pendeteksian kasus pada kategori tersebut. Metode: Dilakukan pencarian literatur dari 4 database (PubMed, ProQuest, ScienceDirect, dan Google Scholar) yang dipublikasi dalam 10 tahun terakhir dengan kata kunci “preoperative”, “braf” atau “braf kinases”, dan “thyroid cancer”. Hasil: Sepuluh studi dengan total 11.239 spesimen yang diklasifikasikan dalam Bethesda III – VI menunjukkan peningkatan sensitivitas yaitu sebesar yaitu 34,8% - 96,62% pada kombinasi teknik FNA dan BRAF. Kesimpulan: Kombinasi pemeriksaan preoperatif FNA dan BRAF mampu meningkatkan sensitivitas serta membantu dalam manajemen inisial kanker tiroid pada nodul tiroid grup ITN atau Bethesda III dan IV dalam pendeteksian keganasan pada tiroid.

Infeksi saluran kemih merupakan salah satu penyebab demam tersering yang dialami oleh anak-anak, terutama anak perempuan. Infeksi saluran kemih digolongkan ke dalam infeksi saluran kemih atas (pielonefritis), saluran bawah (sistitis) dan bakteriuria asimtomatik. Penelitian ini bertujuan mengeksplorasi gejala, diagnosis dan penatalaksanaan infeksi saluran kemih pada anak. Ditemukan bahwa dalam menegakkan diagnosis infeksi saluran kemih, dibutuhkan analisis urin dan pemeriksaan kultur urin, dengan memperhatikan pengambilan sampel urin. Pemeriksaan urinalisis dapat digunakan untuk menegakkan diagnosis dari infeksi saluran kemih jika ditemukan adanya leukosit esterase atau nitrit yang positif dan kultur urine. Penatalaksanaan infeksi saluran kemih pada anak dapat menjadi tantangan karena gejala yang muncul secara samar dan tidak spesifik, namun penatalaksanaan infeksi saluran kemih harus memperhatikan tingkat resistensi, usia anak, lokasi infeksi saluran kemih, tingkat keparahan, dan antibiotik yang diberikan, sedangkan pengobatan terhadap infeksi saluran kemih dilakukan untuk mencegah terjadinya sepsis pada anak, dimana penggunaan antibiotik masih merupakan salah satu terapi utama untuk mengatasi infeksi saluran kemih pada anak. Penggunaan antibiotik pada anak dengan Vesicoureteral Reflux (VUR) bertujuan untuk mengurangi kekambuhan infeksi saluran kemih, sehingga direkomendasikan antimikroba dengan dosis yang rendah.
A review of Quality control in food safety for FMCG Products
Authors: Nikita Mahindrakar
Published: July 2023

For humans, food is essential to their well-being. A country's economy and long-term growth depend on the availability of nutritious food of high quality and safety. The quality and stability of the food supply has become a global issue due to the recent rise in food contamination occurrences and product recalls. Quality management measures in food supply are examined in this study, with an emphasis on McDonald's Hong Kong's use of these procedures to ensure the quality of their food supply. Everyday life revolves on food; thus, it is both practical and philosophically necessary to improve food safety risk governance. Using a reputation updating model, this study proposes a three-tier supply model that includes government regulatory agencies, food producers, and consumers. It also investigates the impact of product quality and sales price for food producers, as well as government testing accuracy and regulations' efficacy in ensuring product quality and safety. There is a negative relationship between pricing and government incentives or penalties, according to these findings. By improving accuracy of food sampling tests in addition to increasing rewards and increasing punishments for poor food quality, product quality can be effectively controlled, and prices can be balanced, resulting in increased profits for food producers. There are several insights about food safety risk management in this study, which may be gleaned from the various observations. The image of a firm suffers a catastrophic hit when problems with food quality and safety are made public, even though the process of changing product quality is relatively gradual for manufacturers.

Study this aim group issuer share in Indonesia based on volatility, liquidity, and market capital. This study uses the non-hierarchical K-Means Clustering method, because the number of samples is big and the number of groups are known. The K-Means Clustering grouping method produces as many as 6 groups with different characteristics. 2. Group 1 consists of stock issuers with quite high volatility and liquidity. The characteristic of group 2 is that it consists of stock issuers with the lowest volatility. Big Capital is the nickname for group 3 because it has market capital or the asset value is very large among all groups and the volatility is very small, and liquid. In Group 4, stock issuers have the highest volatility and the lowest liquidity. Results of profile interpretation in group 5, issuer’s stocks have the highest liquidity and market capital is quite low. Share issuers in group 6 have the volatility highest. Group 3 is recommended as an option for investing. Because, having market capital or large asset values, liquid, and volatility is low enough to minimize risk. The originality of this research is that there is no combination of methods between grouping in fields with k-means clustering and detection of sales with DBSCAN, especially in the field of issuer share in Indonesia.

The aim. The primary objective of the study was to evaluate the effect of food on the bioavailability of Aterixen® 100 mg tablet after single oral dose under fasting or fed conditions. The secondary objective was to evaluate the pharmacokinetic parameters, safety, and tolerability of Aterixen® 100 mg tablet after single oral dose under fasting or fed conditions. Materials and methods. Healthy male and female volunteers aged 18 to 45 years were included in the study. Due to lack of data about intra-individual variability of the main pharmacokinetic parameters of the active substance in Aterixen® (XC221GI, 1-[2-(1-Methylimidazol-4-yl)-ethyl]perhydroazin-2,6-dione), an adaptive group sequential approach was used in the study. At Stage I, 24 volunteers were randomized into 2 groups (12 in each group): Group 1 (sequence AAB) received treatment A (administration of the drug under fasting conditions) during period I, treatment A during period II and treatment B (administration of the drug under fed conditions) during period III, Group 2 (sequence BBA) received therapy B during period I, therapy B during period II, and therapy A during period III. In each study period, serial blood samples were collected before and throughout 12 h after administration of the study drug. The quantification of the active substance XC221GI in plasma samples was performed using a validated high-performance liquid chromatography method with mass spectrometric detection. Safety evaluation was performed on the basis of frequency and severity of adverse events (AEs) and serious adverse events (SAEs), which were registered based on complaints, physical examination, laboratory tests, and electrocardiography (ECG). Drug tolerability was evaluated in terms of proportion of volunteers who prematurely discontinued participation in the study due to AE/SAE. Results. 24 randomized volunteers completed the study in compliance with the approved study protocol. The averaged pharmacokinetic curves profiles of XC221GI had similar shapes under fasting and fed conditions. Confidence intervals for the ratio of the geometric means for the primary parameters (AUC(0-t) and Cmax) of XC221GI and AUC(0-∞) were within the 80-125 % acceptance interval, while a small in absolute value, but statistically significant differences were noted in time until Cmax is reached. Throughout the study, 2 volunteers reported AEs (low RBC count, low hemoglobin concentration, and low hematocrit value) after receiving the study drug under fed conditions. All reported AEs were mild. The relationship between AEs and the study drug product was assessed by investigator as doubtful. Conclusion. The results of this study indicate that food does not affect the bioavailability of Aterixen® 100 mg, tablets, and the single oral dose of 100 mg was safe and well tolerated by healthy volunteers.

The Influence of Intellectual Capital on The Financial Performance of Family Companies and The Role of Family as a Moderation Variable (Case Study: Family Company Listed on The Indonesia Stock Exchange in 2019-2020)
Authors: Aziz Muhammad Alfarizi
Published: July 2023

This study aims to analyze and examine the influence of intellectual capital on the financial performance of family companies with the role of the family as moderating the influence relationship. Intellectual capital is estimated using the Value Added Intellectual Coefficient (VAIC) method developed by Ante Pulic. The company's financial performance is measured by Return on Assets (ROA), Return on Equity (ROE), and Asset Turnover Ratio (ATO). Family role variables were measured using Family Ownership (OWN), Family Board of Directors (BOD), and Family Chief Executive Officer (CEO). The population in this study is a family company that is listed on the Indonesia Stock Exchange (IDX) and has information regarding the final shareholders of the company. The sample used is 98 family companies. The analytical tool used is multiple linear regression with cross section data type. The research year takes and compares 2 different years. The year 2019 aims to reflect conditions before the covid-19 pandemic and 2020 reflects conditions during the covid-19 pandemic. The results showed that intellectual capital is a positive and significant variable affecting the financial performance of family companies in crisis conditions and before the crisis. The role of the family, which was expected to strengthen the influence of VAIC on financial performance, turned out to be the opposite in some indicators.

Palang Merah Indonesia (PMI) noted that the stock of blood in Indonesia reached 87,238 bags as of June 14, 2022, where it should be estimated that Indonesia needs 5.1 million bags of blood every year. The conventional blood donor process procedure is one of the main reasons the younger generation does not intend to donate blood. A new system is needed to regulate the flow of the blood donation process so that it is faster and attracts the interest of young people to donate blood. This research resulted in a blood donation system in the form of a website application for each blood donor unit and a mobile application for users who are blood donors. The system was developed with the Agile method which makes it easy for researchers to adapt to the evolving needs of users. The system usability test is based on Nielsen's Criteria which includes 5 main aspects, including learnability, efficiency, memorability, errors and satisfaction. The results of the trial on the targeted respondents showed that almost all of them were interested in using and would routinely donate blood with the new system that had been built, because it was considered to simplify the blood donation procedure which was previously considered complicated. In addition, data between blood donor units can be well integrated with the system that has been built. In the end, this research has the main goal of changing people's habits, especially young people to continue to regularly donate blood, not only is it good for health, but also can help others in need.

Green Economy is a sustainable economic activity to be able to improve people's welfare without neglecting the impact that causes damage to the environment. This concept prioritizes economic activities with low carbon emissions. Currently, the largest carbon emissions are caused by power plants that still use non-renewable natural resources. One of the efforts made to reduce carbon emissions is to use a solar power plant, known as PV Solarcell. However, with new developments and discoveries for solar power plants, BIPV is perfected. BIPV is a solar power plant where the existing solar panels are attached to buildings or buildings. The aim of this research is to be able to create a new green economy business model for BIPV power plants by using lean canvas tools. This research uses descriptive qualitative method. This research starts from May to October 2022. The results of this study using the lean canvas concept can create an integrated and sustainable green economy business model ecosystem to be able to create new value.
The Dimorphos Boulder Swarm

We present deep Hubble Space Telescope images taken to examine the ejecta from the DART spacecraft impact into asteroid Dimorphos. The images reveal an extensive population of comoving boulders, the largest of which is ∼7 m in diameter (geometric albedo 0.15 assumed). Measurements of 37 boulders show a mean sky-plane velocity dispersion of 0.30 ± 0.03 m s−1, only slightly larger than the 0.24 m s−1 gravitational escape velocity from the Didymos–Dimorphos binary system. The total boulder mass, M

b
∼ 5 × 106 kg (density 2200 kg m−3 assumed), corresponds to about 0.1% of the mass of Dimorphos, and the boulders collectively carry about 3 × 10−5 of the kinetic energy delivered by the DART spacecraft impact. The sky-plane distribution of the boulders is asymmetric, consistent with impact into an inhomogeneous, likely rubble-pile, body. Surface boulder counts on Didymos show that the observed boulder swarm could be ejected from as little as 2% of the surface of Dimorphos (for example, a circular crater at the impact point about 50 m in diameter). The large, slow-moving boulders are potential targets to be investigated in situ by the upcoming ESA HERA mission.

In light of these developments, this paper presents the research background and current state of distributed shop scheduling. It summarizes relevant research on issues that align with the new manufacturing model, explores hot topics and concerns and focuses on the classification of distributed parallel machine scheduling, distributed flow shop scheduling, distributed job shop scheduling and distributed assembly shop scheduling. The paper investigates these scheduling problems in terms of single-objective and multi-objective optimization, as well as processing constraints. It also summarizes the relevant optimization algorithms and their limitations. It also provides an overview of research methods and objects, highlighting the development of solution methods and research trends for new problems. Finally, the paper analyzes future research directions in this field.
Incentives in matching markets: Counting and comparing manipulating agents

Published: July 2023

Manipulability is a threat to the successful design of centralized matching markets. However, in many applications some manipulation is inevitable and the designer wants to compare manipulable mechanisms to select the best among them. We count the number of agents with an incentive to manipulate and rank mechanisms by their level of manipulability. This ranking sheds a new light on practical design decisions such as the design of the entry‐level medical labor market in the United States, and school admissions systems in New York, Chicago, Denver, and many cities in Ghana and the United Kingdom.
