Sexual abuse is emerging as one of the major form of child abuse. In the late 1990s, official reports of sexual abuse began to mushroom at a much more rapid rate than reports of other forms of abuse in Korea. In addition, sexual abuse can cause the most serious emotional-cognitive-behavioral sequelae to victims. Although child & adolescent psychiatrists meet many sexual abuse victims who are referred from many types of child protective services, the psychiatrists may not be likely to give them sufficient and appropriate treatment and guideline for victims and their parents. In this article, the historical concepts, pathophysiological processes, shortterm & longterm sequelae of sexual abuse are reviewed and summarized. And I summarize the intervention and outcome studies for sexual abuse victims. In the close future, the active participation of psychiatrists who help the child and adolescents will be expected in the development of nationwide preventive and therapeutic projects for victims and families of sexual abuse.

만성 폐색전증으로 혈전 제거술을 하고 난 다음 기관지내 대량 출혈은 빈도는 적으나 상당히 높은 사망률을 보이는 합병증 중의 하나이다. 기관지내 대량 출혈이 생겼을 때 체외 막 산소화 장치와 각각 다르게 조절한 인공호흡기 2대를 이용하여 특별한 휴유증 없이 잘 치료한 경험을 하였기에 보고하는 바이다.

작년 9월부터 시작된 미국발 금융대란으로 인해 반년이 지난 지금도 세계 각국에서는 그 휴유증을 앓고 있다. 하지만 경기에는 반드시 굴곡이 있는 법이고, 경기가 하락했다면 언젠가는 다시 상승한다는 불문의 법칙이 있다. 이에 포스코경영연구소(POSRI)에서는 '경기순환을 활용한 불황기 기업전략 보고서'을 내놓았다. 다음은 동 보고서를 정리 요약한 것이다.

Dose distribution of point source represents an inverse square law as the distance, Difference of measurement value and calculation value according to moving distance of radiation source show very large error in dose calculation of Brachytherapy. Therefore, in RALS of high dose rate, dose calculation have an important effect in treatment of uterine cervix cancer and recurrent rate. In this paper, authors measured moving distance of radiation source carrying out RALS. And we measured Rectum dose compared with calculationdose.

Brain abscesses in neonates are extremely rare and usually occur in patients with certain risk factors. A 1-month-old boy presented at the hospital with fever and irritability. As a result of preterm delivery and low birth weight, he had a history of admission to the neonatal intensive care unit. Neuroimaging revealed a large, space-occupying lesion in both frontal lobes, which was suspected to be an abscess with the midline shifting to the right. With a single aspiration and abscess drainage along with concurrent prolonged parenteral antibiotic therapy, the patient showed an excellent treatment outcome with normal development. The focus will be placed on minimally invasive surgical management as well as positive outcomes.

The finding of long lived free radicals produced by ionizing radiation in organic crystals and the quantification of this effect by electron spin resonance(ESR) spactroscopy has proven excellent dosimetric applicability. The tissue equivalent alanine dosimeter also appear appropriate for radiation therapy level dosimetry. The dose measurement was performed in a Rando phantom using high energy photons as produced by high energy medical linear accelerator and cobalt-60 teletherapy unit. The absorbed dose range of the ESR/alanine dosimetry system could be extended down to 0.1 Gy. The response of the alanine dosimeters was determined for photons at different therapeutic dose levels from less than 0.1 Gy to 100 Gy and the depth dose measurements were carried out for photon energies of 1.25MeV, 6 and 10 MV with alanine dosimeters in Rando phantom. Comparisons between ESR/alanine in a Rando phantom and ion chamber in a water phantom were made performing depth dose measurements to examine the agreement of both methods under field conditions.

Purpose: Coronavirus disease 2019 (COVID-19) has posed a significant burden to infant and toddler's care globally, while the disease severity is generally mild in this age group. In this study, we aimed to assess epidemiological and clinical aspects of COVID-19 in infants and toddlers in Seoul, South Korea. Methods: We used Seoul Metropolitan Government's epidemiological investigation database to describe the epidemiological and clinical characteristics of COVID-19 in infants and toddlers, between March 2020 to December 2021. Results: A total of 5,025 infants and toddlers aged <5 years was diagnosed between the observed period. 2,720 (54.1%) had symptoms, and fever was the most common symptom in 1,941 (74.1%). Of the diagnosed cases, 96.4% did not have underlying diseases. In a district level, extended opening of childcare facility was associated with increased risk of COVID-19 in infants and toddlers. Conclusions: An efficient monitoring system, resembling routine clinical care, is crucial, considering the low rates of severe progression and fatality among infants and toddlers. Moreover, a well-grounded intervention based on scientific evidence, rather than unconditional closures, is necessary to establish a suitable childcare policy that ensures safety from infectious diseases while not overlooking the developmental aspects of social skills.

Purpose : Radiotherapy is the main treatment modality for uterine cervix cancer. Since the rectum is in the radiation target volume, rectal bleeding is a common late side effect. This study evaluates the risk factors of radiation induced rectal bleeding and discusses its optimal management. Materials and Methods : total of 213 patients who completed external beam radiation therapy (EBRT) and intracavitary radiation (ICR) between September 1994 and December 1999 were included in this study. No patient had undergone concurrent chemo-radiotherapy. Ninety patients received radiotherapy according to a modified hyperfractionated schedule. A midline block was placed at a pelvic dose of between 30.6 Gy to 39.6 Gy. The total parametrial dose from the EBRT was 51 to 59 Gy depending on the extent of their disease. The Point A dose from the HDR brachytherapy was 28 Gy to 30 Gy $(4\;Gy\times7,\;or\;5\;Gy\times6)$. The rectal point dose was calculated either by the ICRU 38 guideline, or by anterior rectal wall point seen on radiographs, with barium contrast. Rectal bleeding was scored by the LENT/SOMA criteria. For the management of rectal bleeding, we opted for observation, sucralfate enema or coagulation based on the frequency or amount of bleeding. The median follow-up period was 39 months $(12\~86\;months)$. Results : The incidence of rectal bleeding was $12.7\%$ (27/213); graded as 1 in 9 patients, grade 2 in 16 and grade 3 in 2. The overall moderate and severe rectal complication rate was $8.5\%$. Most complications $(92.6\%)$ developed within 2 years following completion of radiotherapy (median 16 months). No patient progressed to rectal fistula or obstruction during the follow-up period. In the univariate analysis, three factors correlated with a high incidence of bleeding an icruCRBED greater than 100 Gy $(19.7\%\;vs.\;4.2\%)$, an EBRT dose to the parametrium over 55 Gy $(22.1\%\;vs.\;5.1\%)$ and higher stages of III and IV $(31.8\%\;vs.\;10.5\%)$. In the multivariate analysis, the icruCRBED was the only significant factor (p>0.0432). The total parametrial dose from the EBRT had borderline significance (p=0.0546). Grade 1 bleeding was controlled without further management (3 patients), or with sucralfate enema 1 to 2 months after treatment. For grade 2 bleeding, sucralfate enema for 1 to 2 months reduced the frequency or amount of bleeding but for residual bleeding, additional coagulation was peformed, where immediate cessation of bleeding was achieved (symptom duration of 3 to 10 months). Grade 3 bleeding lasted for 1 year even with multiple transfusions and coagulations. Conclusion : Moderate and several rectal bleeding occurred in $8.5\%$ of patients, which is comparable with other reports. The most significant risk factor for rectal bleeding was the accumulated dose to the rectum (icruCRBED), which corrected with consideration to biological equivalence. Prompt management of rectal bleeding, with a combination of sucralfate enema and coagulation, reduced the duration of the symptom, and minimized the anxiety/discomfort of patients.
