요 약 갑상선호르몬 내성증후군(GRTH)과 주의력 결핍-과잉행동장애(ADHD)의 간계는 최 근에 매우 연구가 활발히 진행되면서, ADHD환아에서 갑상선 검사를 기본검사로 시행 할 것인가 여부가 또한 논란이 피과 있다. 저자는 ADHD 환아뿐 아니라 발달장애 환아에 서도 GRTH가 발견될 수 있다는 사항에 주목하여 이들 환자들에서 갑상선 검사를 시행하여 이상 유무를 조 사하고, 뚜렷한 이상소견을 보이는 관아들의 임상 양상을 밝혀 앞으로 이들의 가계 연구 및 유전자 연 구의 시작을 해보고자 하였다. 총 51명에서 검사가 시행되었고, 이중 T3,T4가 모두 정상범위를 벗 어나며, TSH가 정상 흑은 증가된 증례가 모두 11명이어다. 그들의 임상 특성과 진단등을 살펴보고, 앞 으로의 방향에 대해 토의하였다. ABSTRACT Recently several studies showed a strong and specific association of Attention-Deficit Hyperactivity Disorder(ADHD) and generalized resistance to thyroid honnone(GRTH). The recommandation that all children with ADHD be screened for GRTH is an newer controversial issue in child psychiatric Held. Author examined thyroid indices(T3, T4, TSH) is suggestive of the finding of GRTH_ cases. Therefore I suggest that child psychiatrist shoul and clinical characteristics in the 51 clinical populations with ADHD, developmental delay, and language disorders. The results are that 11 cases were out of the normal range of both T3 and T4 inspite of normal TSH. This findingd pay attention to ADHD symptoms secondary to GRTH and that all children with familial ADHD and developmental delay(in- cluding launguage disorder) be screened for thyroid abnormalities.

Violence is the most important part for human health by according to WHO. Human violence is the result of a complex interaction of the characteristics of the individual with influences in the environment, Psychiatrists must be prepared to evaluate and treat violent patients, but also are expected to serve as informed commentators regarding violence in society. In this special issues, 4 psychiatrists concerning violence in the clinical practice participated from the point of evaluation and management of violent patients : 1) Family Violence 2) Child Abuse and Neglect 3) Sexual Abuse.

In spite of misconception and/or neglect concerning mental disorders of adolescence, increasing attention to adolescents’ mental health problems arises from a number of sources. A perspective from developmental psychopathology provides a conceptual tool for understanding the range of processes and mechanism underlying how and why psychopathology in adolescents emerges. This will enable primary physicians to diagnose and/or provide treatments to adolescents with mental health problems in clinical practice. More information about mental disorders in adolescents will be needed for primary physicians in the future. Adolescents’ mental disorders are significant societal problem. Physicians should perform a leadership in multidisciplinary approach for diagnosis and treatment of mental disorders in adolescents.

Purpose: We aimed to define the feasibility of the omission of routine insertion of a drain after pure laparoscopic donor nephrectomy (PLDN). We compared the outcomes between those with and without routine drain insertion. Materials and Methods: From July 2014 to October 2018, 178 PLDN were consecutively performed by a single surgeon. Since October 2016, we stopped routine insertion of a drain after PLDN. Thus, the former 80 drained routinely were defined as the Drainage group and the latter 98 were defined as the Non-drainage group. One patient drained non-routinely in the Non-drainage group was excluded from the final analysis. Operative and convalescence parameters and intra- and postoperative complications were compared between the groups. Intra- and postoperative complications within 90 days of surgery were graded using the Satava and Clavien–Dindo classifications, respectively. Results: Baseline characteristics were similar between the groups, except for concomitant surgery, American Society of Anesthesiologists score, and preoperative glomerular filtration rate. All operative and convalescence parameters were similar between the groups, except for postoperative glomerular filtration rate. The rates of overall intra- (22.5% versus 28.9%, p=0.337) and postoperative (62.5% versus 59.8%, p=0.713) complications were similar between the groups. The rates of potentially drain-related postoperative complications were also similar between the groups (36.3% versus 33.0%, p=0.650). Two patients per group suffered from major drain-related complications (2.5% versus 2.1%). Conclusions: PLDN without routine drainage can be performed safely without an increase in postoperative morbidity.

Bulk nanostructured copper was fabricated by a shock compaction method using the planar shock wave generated by a single gas gun system. Nano sized powders, average diameter of 100 nm, were compacted into the capsule and target die, which were designed to eliminate the effect of undesired shock wave, and then impacted with an aluminum alloy target at 400 m/s. Microstructure and mechanical properties of the shock compact specimen were analyzed using an optical microscope (OM), scanning electron microscope (SEM), and micro indentation. Hardness results showed low values (approximately 45~80 Hv) similar or slightly higher than those of conventional coarse grained commercial purity copper. This result indicates the poor quality of bonding between particles. Images from OM and SEM also confirmed that no strong bonding was achieved between them due to the insufficient energy and surface oxygen layer of the powders.
