Objective Mood disorder and borderline personality pathology (BPP) are frequently comorbid and relate to childhood trauma. We investigated the relationship between childhood trauma and BPP features in mood disorder patients versus controls.Methods A total of 488 mood disorder patients, particularly major depressive disorder (MDD), bipolar I disorder (BD I), and bipolar II disorder (BD II), and 734 controls were included. We examined between-group BPP-related differences and correlated between BPP and childhood trauma using the Childhood Trauma Questionnaire-Short Form (CTQ) and the Personality Assessment Inventory–Borderline Features Scale.Results BD II patients showed significantly higher BPP. Emotional abuse and neglect were prominently associated with BPP, while affective instability and negative relationships exhibited a stronger association with childhood trauma. We also found a positive relationship between childhood trauma and BPP in MDD, BD I, and BD II patients.Conclusion The findings of the present study imply that BPP features are more likely to be found in patients with BD II than BD I or MDD. Mood disorder patients with severe childhood trauma may have higher BPP features. Thus, further study of the relationship between childhood trauma and BPP features could improve the therapeutic approaches and help understand patients with mood disorders.
Improvement Measures of Household Pharmaceutical Waste in an Aging Society

Korea has become an aging society and the consumption of pharmaceuticals is increasing. Medicines that are no longer available will eventually be released as household pharmaceutical waste. Many cases of improper disposal and treatment are still being identified. In this study, we surveyed the current status of the 'domestic household pharmaceutical waste collection and treatment business' and investigated the problems of the management system. In addition, improvement measures have been made to increase the collection rate of household pharmaceutical wastes by the elderly and to treat wastes more safely. In particular, online questionnaire survey was conducted on 560 citizens and 351 elderly people to look into how household pharmaceutical wastes are currently being discharged, and to prepare more effective collection strategies. The main issues related to the collection and disposal of household pharmaceutical wastes are as follows. First, there is still a lack of awareness of how and where wastes should be discharged. Second, there is a conflict between practitioners because role assignments are not clear. Third, the collection period of household pharmaceutical wastes is irregular and the regional variation is too large. Only 33% of local governments collected the wastes on a quarterly basis, and 11% collected less than twice a year. Finally, local governments have very low enactment rates of legislation related to household pharmaceutical wastes. By 2016, 85% of all local governments have not enacted ordinances. The following improvements measures were suggested in this study. First, information and publicity about those who dispose the wastes should be strengthened. Second, the role of the implementing bodies needs to be clarified. This study suggested the specific role of each stakeholder (citizen, pharmacy, pharmacy association, manufacturer, local government). Third, it is important to consider the collection cost of each type of local government. Three representative local governments were selected to conduct cost analysis from collection to final incineration. As a result, close cooperation between stakeholders plays an important role in the safe treatment of pharmaceutical waste. Fourth, there is a need to provide information on the disposal of household pharmaceutical waste to the elderly and improve the waste collection system. Finally, from the mid- to long-term, it is possible to consider improving the entire management system from the stage of production through ‘preliminary environmental risk assessment system’.

Purpose: To investigate whether the signal or morphological changes in the adjacent bone or soft tissue after intradiscal electrothermal therapy (IDET) occur due to postprocedural inflammation or infectious spondylodiscitis. Materials and Methods: Ten patients (female:male = 5:5; age range, 18–71 years; mean age: 36.5 years) who underwent lumbar IDET between January 2018 and December 2020 and complained of fever or pain were included in this study. The presence and extent of bone marrow and paraspinal soft tissue signal changes were evaluated using the first follow-up magnetic resonance imaging (MRI) after IDET. Signal changes in the treated discs and the presence and extent of epidural enhancement were evaluated. Additionally, we investigated the presence and margins of subchondral erosions in the vertebral body. Results: Two radiologists analyzed the imaging findings by consensus. Six patients were diagnosed with postprocedural inflammation and four with infectious spondylodiscitis, which was confirmed by specimen culture after surgery. All 10 patients showed signal changes in the bone marrow of the vertebral bodies adjacent to the treated disc. Signal changes in the paraspinal soft tissue were observed in only five patients: three with infectious spondylodiscitis and two with postprocedural inflammation. In six patients with postprocedural inflammation, subchondral erosions had well-defined margins with a sclerotic rim and in four patients with infectious spondylodiscitis, subchondral erosions had ill-defined margins. Epidural enhancement showed an extensive pattern in all cases of infectious spondylodiscitis and localized patterns in cases of postprocedural inflammation. Conclusion: MRI or computed tomography findings of well-defined subchondral erosions with a sclerotic rim and more localized signal changes in the paraspinal soft tissue or epidural space might aid in the differentiation of infectious spondylodiscitis and postprocedural inflammation in patients who underwent IDET.
Management Strategies for Promoting Recycling of Waste Solar Panels

Solar power generation has shown the highest installation rate among renewable energy sources in Korea. Although very large amount of waste solar panels, including panels that have been damaged or have reached their end of life, are expected to be discarded in the next few years, there is no collection and management system for waste panels. Meanwhile, foreign countries such as the EU and Japan have already recognized the issue of waste solar panels and have taken appropriate strategies. This study investigated the current management status of waste panels and suggested improvement measures for promoting recycling. Here, domestic solar panels can be divided into ‘waste panels after use’ and ‘by-products generated in the manufacturing processes’. In particular, ‘waste panels’ include both ‘reusable panels being exported overseas’ and ‘non-reusable waste panels that are discarded in landfills’. Based on the classification, we analyzed the waste streams after disposal of solar panels and conducted quantitative analysis of heavy metals in cooperation with the National Institute of Environmental Research to examine the environmental impact of waste panels. As a result, we identified the following major issues. First, the management system for waste panels should be strengthened. In the case of domestic solar power generation facilities, there are provisions for installation, but there is no post-treatment of solar panels. Some panels are treated as mixed construction waste, but the method is not legitimate under 「Construction Waste Recycling Promotion Act」. Second, there is no statistical system for waste solar panels. So far, the amount of discarded waste panels is not yet known. Third, it is necessary to establish a domestic certification scheme for the reuse of waste panels. Until now, reusable panels have been exported to a few developing countries. However, overseas markets may be blocked depending on the economic situation. Fourth, most of the waste panels except the exported products are either left as they are or sent to the landfill. Finally, there are no safety guidelines for dismantling and transporting waste panels. To address the current issues of waste panels, we suggested improvement measures such as building a management system for effective collection and proper treatment, a domestic reuse market, technical support to recycle waste panels at low cost, and safety guidelines after disposal of waste panels. These solutions would contribute to building lifecycle resource circulation systems, from Eco-design to recycling waste solar panels.
