Non-suicidal self-injury (NSSI) and substance addiction have seen a significant rise among adolescents and young adults in re-cent years. This increase is closely linked to digitalization of the modern society, which has dramatically altered how young in-dividuals interact and communicate. Although the use of smartphones, social media, and online interactions has facilitated fast information exchange and increased connectivity, it has also contributed to heightened emotional distress, isolation, and a sense of inner emptiness. NSSI and addiction are seemingly distinct issues. However, they share underlying psychological mecha-nisms such as emotional dysregulation and the reliance on harmful behaviors to cope with psychological pain. These behaviors often serve as attempts to manage unprocessed negative emotions and unresolved inner conflicts. This paper explores NSSI and addiction from a psychoanalytic perspective, focusing on psychological complexities that drive these behaviors. It also exam-ines how the lack of real-object experiences in a digital environment can lead to inner voids that individuals attempt to fill through self-destructive behaviors. The importance of understanding these phenomena from a psychoanalytic standpoint is em-phasized. It provides deeper insight into underlying causes and guides therapeutic approaches. By acting as a developmental ob-ject, a therapist can help patients address unmet developmental needs, mitigate inner conflicts, and establish healthier selfboundaries. This approach is crucial for enabling effective intervention and fostering long-term emotional stability.

OBJECTIVES: The author investigated the relationship between the environmental tobacco smoke exposure during mid-pregnancy and early childhood and neurobehavioral outcomes of preschool children and if there is any effect of the genetic polymorphism of glutathione S-transferase (GST) M1 and T1 on this relationship. METHODS: The participants were the pregnant women (week 24-28) who visited the obstetrics and gynecology department (between 2001 and 2004). They had been evaluated for their sociodemographic data including direct and environmental tobacco smoke exposure history and the urine specimen had been sampled for the measurement of cotinine. The offsprings' urine specimen and blood sampling had been done and the socioeconomic data including the environmental tobacco smoke exposure history was evaluated at age 3. The cotinine level of urine specimen was measured and GST polymorphism was analyzed. The offsprings completed Korean-Childhood Behavioral Check List (K-CBCL) at age 4-5. RESULTS: The environmental tobacco smoke exposure during mid-pregnancy based on urine cotinine level has a significant association with increased total score and externalizing problem score of K-CBCL (p<0.05). The environmental tobacco smoke exposure based on urine cotinine level at age 3 is associated increased total score, externalizing problem score and internalizing problem score of K-CBCL with no statistical significance. The environmental tobacco smoke exposure after controlling for tobacco smoke exposure during pregnancy, however, is significantly associated with the increased externalizing problem scores (p=0.04). The environmental tobacco smoke exposure is associated with increased total score, externalizing problem score and internalizing problem score of K-CBCL with GSTM1 null type or GSTT1 null type at age 3 although there was no statistical significance. CONCLUSION: The environmental tobacco smoking exposure during pregnancy and at early childhood is associated with childhood behavioral problems. The clinical implication of this study is that it is important to avoid the environmental tobacco smoke exposure during pregnancy and early childhood and to monitor the possible emergence of behavioral problems of children.
