A study on civil liability of Artificial Intelligence
Authors: Lee Sookyoung ,   Korean Civil Law Association
Published: July 2024

The recent development of artificial intelligence (AI) technology is bringing about changes at a faster pace and on a larger scale than any other period in human history. With technological advancements overcoming the limitations of medical AI through training with databases, AI technology has made remarkable progress since the inception of deep learning for image processing with convolutional neural networks (CNN) in 2012. The recent advancements in natural language processing (NLP) have accelerated the utilization of AI through sophisticated natural language processing, enabling machines to identify and understand data regardless of the complexity of the language. This has laid the foundation for the rapid and precise development of generative AI. In the era where generative AI is being utilized without pausing in its developmental speed, we considered the civil liability of AI in our civil law principles, taking into account the inherent characteristics of AI such as unpredictability, opacity, and the black box effect.
To do this, we first examined the legal liability considering the stages of AI technology development in discussing the tort liability caused by AI. Even “Weak AI,” created by AI developers, may fall under “Gefahr,” and while not all types, some may apply to strict liability in terms of risk liability. Furthermore, while reviewing civil liability applicable to AI under fault-based and no-fault liability, we also looked at the trends in the EU comparatively.
In discussing no-fault liability, particularly under the Product Liability Act, we examined the possibility and implications of applying risk liability to pharmaceutical manufacturing using generative AI technology as a representative example to overcome the limitations of the existing Product Liability Act. Humanity currently lives in an era of rapid technological development and exploding big data, enjoying numerous benefits due to these advancements. As user convenience improves and massive added value is created through technological progress, the meaning of risk liability in the realm of civil liability can gain more significance. Generative AI has already drastically reduced the costs and time required for new drug development, providing substantial profits to pharmaceutical companies. However, even if the existing Product Liability Act is applied, it may be difficult to adequately remedy the harm to victims due to the reasonable alternative possibility defense regarding design defects. In the era of generative AI, we examined the possibility of applying enhanced risk liability by assuming the case of pharmaceutical manufacturing.

Published: July 2024

This study assesses the relationship between customer care-specific attributes and the customer growth of quoted deposit money banks in Nigeria. In this study, a cross-sectional survey, which is a quasi-experimental method, was employed. This study encompasses the entire Survey Respondents of 105 sample staffs and their bank customers of the 14 quoted money deposit banks in Nigeria, serving as the accessible population for the study. Data Collection Method was the Primary Data Collection designed questionnaire. The Likert scale, consisting of response options such as Strongly Agree, Agree, Disagree, and Strongly Disagree, was employed. The study used Spearman's rho correlation to observe the statistical significance at 1% level. The result showed that p-values for all correlations are highly significant (p < 0.01), suggesting strong evidence that these relationships are meaningful. This provides confidence in the model's fitness in terms of statistical significance in the given results, with the highest being between customer growth and the number of financial products (0.494), indicating a moderate positive relationship. The coefficients show the strength of the relationships, with high values indicating stronger associations. The model's relationships are robust and not due to random chance, indicating good fitness. It was recommended that banks should ensure that customer service personnel are accessible, responsive, and effective by investing in convenient customer service channels. They should regularly provide training and development opportunities for bank customer service personnel to ensure that they can handle customer inquiries and issues effectively. They should recognize and reward the efforts of bank customer service personnel with fair and competitive salaries and benefits to motivate and retain top talent. They should also diversify the range of financial products offered by banks to meet varying customer needs and attract a broader customer base.

Published: July 2024

A 64-year-old man was brought to the Emergency Department aftera sudden onset of severe left back pain. His medical history revealed human immunodeficiency virus (HIV) and pneumocystis pneumonia (PCP). Abdominal echocardiography and contrast-enhanced computed tomography (CT) scan showed adrenal hemorrhage, and an emergency interventional radiology (IVR) was performed. IVR images are shown in Figure 1. Bleeding from the left inferior adrenal artery was shown and hemostasis by transcatheter arterial embolization (TAE) (Figure 2) was performed. The cause of the hemorrhage was unknown, various culture results were negative, and the CT showed no neoplastic lesion. His serology was negative for pheochromocytoma and coagulation studies were normal and with no history of trauma. He progressed stably postoperatively and was discharged on the 14th day of hospitalization.

Authors: Dimeas Ilias E ,   Department of Respiratory Medicine, Faculty of Medicine, University of Thessaly, Biopolis, 41500, Larissa, Greece.
Published: July 2024

We present a unique case of parapneumonic effusion from an unusual microorganism on a 65-year-old ex-smoker with a history of arterial hypertension and diabetes mellitus, following dental procedures for a periapical tooth abscess. Cultures from the dental abscess were taken, coming back negative. However, some days after the procedure, fever and pleurodynia started showing up on the patient with his condition progressively worsening, until he visited the emergency room of the hospital. Laboratory exams and imaging were consistent with a complicated pneumonia with parapneumonic effusion. After ultrasound-guided evacuation of the effusion, Parvimonas micra (P. micra) was isolated from pleural fluid cultures, so antibiotics were accordingly modified on the treatment plan. The patient responded well, and clinical and radiological improvements were observed. This case highlights the rare occurrence of P. micra-associated pleuropulmonary infection, because of the difficulty to be isolated in the aerobic environment of the lungs, and underscores the importance of considering dental procedures as a potential source of such infections. Early diagnosis and appropriate antibiotic therapy, guided by culture and sensitivity testing, are essential for successful management.
Placental site trophoblastic tumor with lung metastasis: A case report and literature review
Authors: Luo Shuang
Published: July 2024

Placental Trophoblastic Tumor (PSTT) is a rare Gestational Trophoblastic Disease (GTD), which is uncommon in clinical practice. Imaging examinations show no specificity, and it may metastasize to the lung, liver, vagina, or uterine adnexa. Patients with metastasis often face challenges in diagnosis, and the final diagnosis depends on histopathological examination. Lung metastasis is one of the most common sites. We describe the case of a 46-year-old female patient with PSTT and lung metastasis which mechanism is complex, without heterogeneity, but successfully treated with radical hysterectomy and postoperative chemotherapy. The case highlights: (1) The difficulty in the preoperative diagnosis of PSTT, requiring multiple tissue biopsies. (2) Imaging suggests the possibility of pulmonary metastasis, necessitating multidisciplinary management. (3) Monitoring serum β-HCG levels and the size of metastatic lesions was instructive for early diagnosis, outcome evaluation, and follow-up.

Discussion: Tongue metastases are unusual, often mimicking benign lesions, making diagnosis challenging. Treatment options include surgery, radiotherapy, and chemotherapy, but prognosis remains poor. Conclusion: Although rare, tongue metastases from lung cancer pose diagnostic challenges, emphasizing the importance of understanding their clinical characteristics and treatment options.
Symmetrical peripheral gangrene: A rare case with unpredictable presentation and tragic outcome
Authors: Hussain Rameez ,   Department of Medicine, Dow University of Health Sciences, Pakistan.
Published: July 2024

Symmetrical peripheral gangrene (SPG) is a rare condition characterized by acute ischemic damage in multiple extremities without any obstruction or vasculitis in the supplying vessels. It commonly affects the toes, hands, scrotum, and earlobes, increasing the risk of limb amputation and significantly impacting the patient’s quality of life. The underlying vascular injury mechanism is disseminated intravascular coagulation, and SPG can manifest unpredictably in conditions associated with septic shock, low output states, vasospastic conditions, myeloproliferative disorders, or hyper viscosity syndrome. In this case study, a 19-year-old woman presented with bluish-black blisters on her feet and legs, accompanied by pain. The blisters gradually increased in size and burst, resulting in a watery discharge tinged with blood. Despite various investigations and treatments involving multiple departments, the patient ultimately succumbed to septic shock and passed away on June 13, 2023, as confirmed by a house officer and a senior resident.
The diagnostic dilemma in ovarian ectopic pregnancy
Authors: Cheng Chun Phoy ,   Senior Resident, Department of Obstetrics & Gynaecology, KK Women’s & Children’s Hospital, 100 Bukit Timah Road, Singapore.
Published: July 2024

Diagnosis of ovarian ectopic pregnancy (OEP) is challenging because of its rarity. We report a case of 30-year-old woman who presented with abdominal pain. Her pelvic ultrasound showed bilateral ovarian cysts and a right adnexal mass which was separated from the right ovary. OEP was diagnosed intraoperatively with histological confirmation. Diagnostic dilemma is expected, either via imaging or intraoperatively as OEP can mimic appearance of ovarian cysts and blood clots. Preoperatively, patients should be counselled adequately regarding the possible intraoperative findings and their treatments. Surgeons should have the technical abilities to perform ovarian ectopic excision or have minimally invasive surgery specialist available to perform the operation. In conclusion, identification of OEP remains a challenge. Therefore, high clinical suspicion and improved imaging skills are warranted.

Authors: Antonis Theofilidis ,   Propaedeutic Surgery Department, AHEPA University Hospital of Thessaloniki, Greece.
Published: July 2024

The burden of negative emotional states, such as anxiety and depression and stress in people undergoing surgery it is indisputable, because it is a critical event that often happens perceived as an unfamiliar and frightening experience. Nursing also independently from the disease, often causes anxiety in many patients, who are going to be operated on. If constant and prolonged stress is not diagnosed early, can harm the patient and delay his recovery [1]. Perioperative anxiety is a significantly aggravating factor against the preparation of patients before a surgical operation. All are influenced by individual differences and its characteristics personality of each person, such as: Age, nutritional status, chronic conditions diseases or disabilities, surgical procedure (location, type and extent; surgery), as well as previous surgical experiences.

A case report of endovascular treatment of a fast-growing inflammatory abdominal aortic aneurysm in a patient with Staphylococcus aureus sepsis
Authors: Ivanova Patricija ,   Department of Vascular Surgery, Riga Eastern Clinical University Hospital, Latvia.
Published: July 2024

Abdominal Aortic Aneurysm (AAA) and its subsequent rupture is one of the life-threatening conditions. The most common type of arterial aneurysm, AAA, becomes significant at a diameter greater than 3 cm. The mean growth rate of an AAA is 2-3 mm per year, and surgical repair is usually recommended if the diameter exceeds 5.5 cm, in men and 5.0 to 5.2 cm, in women. Faster-growing aneurysms are more aggressive and have a greater risk of rupture. We report a case of a 64-year-old, comorbid male patient who was found to have a previously unknown, but a rapidly growing AAA, which grew from 6cm to 8 cm within just 3 weeks. He was admitted in the emergency department with complaints of worsening dyspnea even without exertion. Upon thorough diagnostic tests, the severity of the overall medical condition was determined by S. aureus sepsis, decompensation of cardiovascular disease, and secondary kidney injury due to septic shock. While receiving treatment for sepsis, a diagnostic CT imaging was done, which confirmed bilateral pneumonia and retroperitoneal abscess in m. psoas major mass, and an infrarenal abdominal aortic aneurysm, which was 6cm in diameter at the time of diagnosis. Another control CT of the lungs and abdomen was performed three weeks later, indicating the pneumonia was slowly resolving, while the aortic aneurysm increased in dynamic; the diameter was 8 cm with a penetrating exudation on the left side, m. psoas abscess was still observed, but decreasing. Because the AAA was very fast-growing, it greatly increased the risk of its rupture, therefore a decision was made to perform endovascular abdominal aortic aneurysm repair, despite the risk of stent infection, given the patients septic background. The goal of this case report is to highlight the rare case of a rapidly growing inflammatory aneurysm and its successful endovascular management. While it’s known that 5-10% of all AAA are inflammatory, cases of surgical treatment in the setting of sepsis are basically non-existent in the literature [1].

Published: July 2024

Introduction: Anal suppurations (fistula and abscess) correspond to two progressive phases of the same disease, characterised by an infection of cryptic origin in the anal canal. The objectives of this study were to determine the hospital frequency, to describe the clinical aspects and to determine the therapeutic modalities of anal suppurations in the department. Methodology: This was a one-year dynamic descriptive study of patients admitted to and operated on for anal suppuration in the Department of Visceral Surgery, Donka National Hospital, Conakry University Hospital. Results: Out of a total of 351 patients operated on, we recorded 21 cases of anal suppuration, i.e. 5.98%. Anal suppuration accounted for 45.65% of all proctological disorders. The average age was 43.09 years. There was a clear male predominance (95.23%) with a sex ratio of 20:1. The clinical picture was dominated by anal discharge and evidence of skin orifices. Retroviral serology, haemogram, HBsAg and blood glucose were performed in all patients. All patients were treated surgically. Post-operative management was straightforward in 95.23% of cases, with complications occurring in 4.76%. Conclusion: Anal suppuration remains by far the most frequent proctological disease in our practice. They constitute a real public health problem because they are underestimated in the African population due to socio-cultural factors. Diagnosis is essentially clinical and treatment is surgical.

Published: July 2024

Sustainable procurement, the acquisition of goods and services that ensures positive environmental, social, and economic impacts, is essential for contemporary business practices. This paper explores the integration of compliance, ethics, and cost-effectiveness within sustainable procurement. Compliance is governed by regulatory frameworks like ISO 20400 and government regulations, ensuring adherence to sustainability standards. Ethical procurement upholds fairness, transparency, integrity, and human rights principles, positively impacting stakeholders such as suppliers, employees, and communities. Cost-effectiveness in sustainable procurement brings significant economic benefits, including cost savings, efficiency gains, and long-term financial advantages. A holistic approach integrating these elements is crucial for developing a sustainable procurement strategy. Organizations are encouraged to prioritize sustainable procurement by developing clear policies, engaging stakeholders, providing training, managing suppliers effectively, and leveraging technology. The paper concludes that balancing these three aspects fosters trust among stakeholders, enhances brand reputation, and ensures long-term operational efficiency, contributing to broader sustainability goals and driving overall organizational success.

Published: July 2024

Indian gooseberry juice (20% (v/v) was reconstituted with 5% ginger juice (v/v) extracted from freshly harvested rhizomes, 2% each of turmeric rhizome powder and black pepper powder (w/v), followed by raising the total soluble solids to 130Brix by adding sugar syrup.  Finally, 5% acid lime juice of 2.45% of titratable citric acid was added to the entire mixture in order to impart a fruity flavour to the product. The entire mixture was homogenized at 175 Bar (2500 psi) with a speed of 235 rpm and was subsequently pasteurized at 1000C for 10 minutes. LC-MS/MS analysis detected phenolic compounds (2-galloyl glucose, 2,6-galloyl glucose), capsaicinoids, curcuminoids, gingerol and shogaol. Though cyclophosphamide significantly inhibited the relative weight of thymus from 0.193 ± 0.048 in normal mice to 0.077 ± 0.034, treatment with the herbal drink significantly increased the relative weight of thymus, showing increased T cell differentiation. Mice treated with the drink showed marginal increase in the WBC count, indicating recovery of immunity. Recovery of bone marrow cellularity in mice fed with the herbal drink was directly proportional to the concentration of the drink. Increase in a-esterase activity was also directly proportional to the concentration of herbal beverage.

Authors: Goode Elizabeth , Roche Thomas , Wilson Erica , Zhang Jacky , McKenzie John W.
Published: July 2024

Despite growing interest in immersive block models in higher education, very little is known about the experiences of international students in these non-traditional forms of learning. To enable an initial view of how international students perceive and perform in an immersive block model, we used an exploratory mixed methods approach to examine the academic success, satisfaction, and experiences of international students in a 6-week immersive block model at a regional public Australian university. Inferential statistical tests were used to explore the success rates and unit and teaching satisfaction of onshore and offshore international students in the immersive block model and in the traditional trimester model. Overall, the immersive block model made a significant positive difference to the academic success of international students, both onshore and offshore. However, a decline in satisfaction was observed among science and engineering students, contrasting with an increase in satisfaction among business and arts students. Data collected through semi-guided interviews with 10 students from this latter group indicate several key benefits and challenges associated with immersive block learning. Students reported heightened focus and motivation, supportive teaching, and a healthy study-work-life balance. Challenges included not knowing what to expect, forming social connections with classmates, and the fast turnover between assessments. These findings indicate that it is important for institutions to prepare international students well for the pace and time management demands of studying in an immersive block model and to encourage the formation of social connections. Assessment timing, volume, and scaffolding should also be key considerations in immersive block model curriculum design.
Intensive Modes of Study and the Need to Focus on the Process of Learning in Higher Education
Authors: Lodge Jason M. , Ashford-Rowe Kevin
Published: July 2024

In the context of a constantly evolving international higher education sector, this commentary emphasises the need for consilience between basic research on learning processes and observations from intensive modes of study. Following a discussion of conflicting evidence on optimal learning time frames, we advocate for seeking alignment between classroom practices with underlying learning mechanisms. We argue for a unified understanding of effective learning beyond notions of the credit point hour or volume of learning, focusing on processes rather than mere inputs and outputs. A collaborative approach between researchers, educators, and policymakers aiming for consilience has the potential to provide practical insights and strategies to enhance student learning and success. Understanding the mechanisms beneath the impact of intensive modes of study, as outlined in this special issue, has the potential to advance the conversation about quality higher education for the 21st century.

Published: July 2024

More than 16% of the total electricity used worldwide is met by hydropower, having local to regional environmental consequences. Pakistan's Environmental Protection Ordinance (PEPO) 1983 mandated Environmental Impact Assessment (EIA). In the Shangla District, the village of Kuz Kana is located about 300 meters upstream of the run-of-river project known as the Karora Hydropower project. The study reviewed the Environmental Impact Assessment and mitigating methods for the Karora hydropower project, Shangla, Pakistan. The authors analyzed the impact area, land resources, water resources, flora and fauna, and the Socio-Economic setup of district Shangla. They also consulted with stakeholders to address potential impacts, issues raised, and compensations according to regulations. According to the survey, the cumulative negative effect of acquiring 64.321 kanals of land will impact around 18 landowners. Only 0.14% and 0.11% of the land in the villages of Kuz Kana and Ranial, respectively, needs to be acquired compared to the proposed area with the complete community. The affected individuals and communities received complete compensation for their losses following the Land Acquisition Act (1984), KPK practice, and ADB policy on “Involuntary Resettlement.” The study concluded that the project has no adverse environmental effects, and the minor potential impacts and compensation were done smoothly per the regulations. The lack of meaningful involvement by the public in the dam construction process is a key critique, which is especially essential for local communities directly impacted by hydropower projects. The study recommended implementing the environmental impact assessment for all hydropower projects in Pakistan.
OCCURRENCES OF SOLID INCLUSIONS OF SILICATE AND BASE METAL SULFIDE MINERALS IN CHROMITITE OF KHANOZAI OPHIOLITE, PAKISTAN: EVIDENCE FROM MELT EVALUATIONS
Authors: Khan Muhammad Ayoub , Abdul Manan Razzaq , Panezai Muhammad , , Abdullah
Published: July 2024

Chromitite bodies occur in the wide mantle portion of Khanozai ophiolite. This peridotite is largely composed of harzburgite, dunite and minor lherzolite. Chromitite occurs in Khanozai ophiolite mainly in massive, disseminated, banded and nodular forms. The Khanozai chromitites contains a variety of silicate and BMS mineral inclusions. They include anhydrous silicates like olivine, clinopyroxene, hydrous silicate inclusions of amphibole, and BMS mineral inclusions such as millerite, chalcopyrite, stibnite, and occasional pyrite and linnaeite. The silicate mineral inclusions occur as monomineralic as well as polymineralic phases. The shapes of these inclusions tend to follow the growth plane of host chromite. Textures and forms of these inclusions reveal that some inclusions were trapped during magmatic stage, whereas many inclusions were trapped during recrystallization of chromite. BMS inclusions are millerite, chalcopyrite, and stibnite. They occur isolated inclusions and at some places associated with silicate mineral inclusions. It is suggested that these BMS inclusions were generated due to the separation of sulfide-bearing liquid from silicate magma.

PT. X is a company that manufactures sugar. The situation of firm X cannot be described as ideal due to the need for extensive study, particularly on the cane cutter's blade. A common indication of cane cutters is a rapid rate of wear. In this study, researchers employed a qualitative technique based on the taguchi method. The taguchi approach is a modern engineering technique that strives to improve the quality of products and processes while reducing costs and maximizing resources. The taguchi experimental strategy is more effective because it permits research incorporating a large number of variables and numbers. Since a larger hardness response is preferable, the largest confirmation value is the ideal parameter value for the knife manufacturing process on the cane cutter. When measuring the hardness of the blade material on a cane cutter, temperature is a highly important component. According to the findings of the hardness test, the hardest material at a temperature of 750oC and a cooling medium of NaCl solution with a hardness value of 12.4 HRC is, and the hardest material at a temperature of 800oC and a cooling medium of NaOH solution with a hardness value of 59.7 HRC is.

Water scarcity and water contamination are among the most challenging global issues today. Wastewater discharged into water bodies that are not appropriately managed causes a decrease in water quality, one of which is laundry wastewater which contains many hazardous materials resulting from the use of detergents and clothes deodorizers. This wastewater pollution management control uses a repeated filtration system with activated carbon as the main ingredient. This aims to determine the effectiveness of reducing the concentration of Chemical Oxygen Demand (COD), water turbidity, and odor level. Activated carbon effectively reduced the COD number from 964 Mg/L to 14 Mg/L. The turbidity level of water decreased from 302 to 2.29 on the NTU scale. This shows that a simple filtration system with activated carbon as the main ingredient for laundry wastewater treatment is very efficient in reducing COD levels, water turbidity levels, and odors from wastewater.
