Severe muddy water problem has been the hot issue in Korea. Because of increased nonpoint source pollutions at Kangwon province, best soil erosion management system is required to reduce inflow of nonpoint source pollutions into the waterbodies. The USLE-based SATEEC system have been developed and enhanced for soil erosion and sediment yield estimation. However, the SATEEC cannot estimate soil depositions depending on topography in the watershed, while the USPED estimates soil erosion and deposition using sediment transport capacity of the surface runoff. In this study, the SATEEC and USPED were used to determine soil erosion hot spot subbasins. For this, 54 subbasins were delineated. In general, soil erosion hot spot subbasins were identified similarly with SATEEC and USPED. However, depending on erosion and deposition patterns in each subbasin. USPED estimated soil erosion hot spot subbasins didn't match those estimated with SATEEC. For some subbasins, much deposition was expected than erosion. This indicates that SATEEC estimated soil erosion values may be overestimated for these subbasins. Thus, care should be taken when understanding soil erosion status in the watershed based on USLE-based SATEEC results. In addition, the USPED results could be used to identify the site-specific soil erosion best management practices. If the USPED and USLE-based SATEEC are combined, it would help determining soil erosion hot spot subwatersheds in economic and environmental perspectives.

Purpose: Diencephalic syndrome is an uncommon cause of failure to thrive in early childhood that is associated with central nervous system neoplasms in the hypothalamic-optic chiasmatic region. It is characterized by complex signs and symptoms related to hypothalamic dysfunction; such nonspecific clinical features may delay diagnosis of the brain tumor. In this study, we analyzed a series of cases in order to define characteristic features of diencephalic syndrome. Methods: We performed a retrospective study of 8 patients with diencephalic syndrome (age, 5-38 months). All cases had presented to Seoul National University Children's Hospital between 1995 and 2013, with the chief complaint of poor weight gain. Results: Diencephalic syndrome with central nervous system (CNS) neoplasm was identified in 8 patients. The mean age at which symptoms were noted was $18{\pm}10.5$ months, and diagnosis after symptom onset was made at the mean age of $11{\pm}9.7$ months. The mean z score was $-3.15{\pm}1.14$ for weight, $-0.12{\pm}1.05$ for height, $1.01{\pm}1.58$ for head circumference, and $-1.76{\pm}1.97$ for weight-for-height. Clinical features included failure to thrive (n=8), hydrocephalus (n=5), recurrent vomiting (n=5), strabismus (n=2), developmental delay (n=2), hyperactivity (n=1), nystagmus (n=1), and diarrhea (n=1). On follow-up evaluation, 3 patients showed improvement and remained in stable remission, 2 patients were still receiving chemotherapy, and 3 patients were discharged for palliative care. Conclusion: Diencephalic syndrome is a rare cause of failure to thrive, and diagnosis is frequently delayed. Thus, it is important to consider the possibility of a CNS neoplasm as a cause of failure to thrive and to ensure early diagnosis.

오늘날 말기 신부전 환자에서의 심장수술은 보편화 되는 추세이며, 만성 신부전 환자들의 수가 늘어남에 따라 이들 환자에 대한 적절한 치료법 개발이 필요하게 되었다. 이 환자들에게는 관상동맥질환 뿐만 아니라 판막질환도 드물지 않다. 이들에게 시행되는 복막투석은 체외순환에 다소의 지장은 있을수 있지만 수술 전후에 적절한 대책을 준비한다면 더 이상 심장수술의 걸림돌이 되지 않는다. 저자는 심한 승모판막 폐쇄부전과 만성신부전을 동반한 33세의 무뇨증 여자환자에서 기계판막치환술을 시행하였다. 환자는 수술전에 복막투석을 주기적으로 함으로써 수분 및 전해질 균형을 적절히 유지시켰고, 수술후에도 혈액 생화학적 검사결과를 수시로 예의검토하면서 복막투석을 계속시행함으로써 무사히 회복될 수 있었다.

Purpose: Minimally invasive surfactant therapy (MIST) is currently used as a method of surfactant replacement therapy (SRT) for the treatment of respiratory distress syndrome (RDS) in preterm infants with a gestational age of less than 30 weeks. However, few studies have been conducted on MIST in neonates with a gestational age of 30 weeks or more. In this study, we compared MIST with endotracheal intubation as a rescue SRT for spontaneously breathing neonates with a gestational age of 30 weeks or more who were diagnosed with RDS. Methods: We investigated the clinical characteristics of spontaneously breathing neonates admitted to the neonatal intensive care unit of the Inje University Sanggye Paik Hospital from January 1, 2014 to December 31, 2016. These neonates were born at a gestational age of 30 weeks or more and were diagnosed with RDS. The neonates who were administered surfactant by MIST were categorized into the MIST group (n=16) and those who underwent endotracheal intubation were categorized into the control group (n=45). Thereafter, the clinical characteristics between the groups were compared. Results: Compared to the control group, the MIST group was less likely to require mechanical ventilation within 72 hours (P<0.001). The frequency of bradycardia during SRT was also low in the MIST group (P=0.033). Conclusion: MIST is considered relatively feasible and safe for treating RDS for reducing the need for mechanical ventilation and decreasing the occurrence of bradycardia during surfactant administration in neonates with a gestational age of 30 weeks or more.

The purpose of this study was to investigate pregnancy, abortion and delivery rates among Korean teenagers. The subjects of this study were 11,433 teenagers aged 13-19 years in Seoul, Pusan, Taegu, Kwangju, Incheon, Taejeon and Ansan, Korea. Data were collected from Feb. 1994 to May 1995, 16 months, by schoolnurses or the researchers. The results showed pregnancy rate was 7.2 per 1,000 teenagers, the abortion rate was 4.3 per 1,000 teenagers, and the delivery rate was 1.2 per 1,000 teenagers. In the pregnancy experience, the main factors related to teenage pregnancy were love or marriage engagement. In the abortion experience, 53.9% of teenagers had had more than two abortion experiences, 38.1% midtrimester abortion, 22% complications after abortion, 36.0% sexual activity after abortion and 86.7% the financial support from partners or friends for abortion. In the delivery experience, 64.3% of teenagers delivered with no prenatal care and 42.9% had a delay in realizing they were pregnant. Fifty percent were delivered by non-professionals in non-medical institutions.

Objectives: An outbreak of acute febrile illness occurred in the Republic of Korea Air Force boot camp from May to July 2011. An epidemiological investigation of the causative agent, which was of a highly infective nature, was conducted. Methods: Throat swabs were carried out and a multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) assay was performed to identify possible causative factors. Results: The mean age of patients who had febrile illness during the study period was 20.24 years. The multiplex RT-PCR assay identified respiratory syncytial virus (RSV) as the causative agent. The main symptoms were sore throat (76.0%), sputum (72.8%), cough (72.1%), tonsillar hypertrophy (67.9%), and rhinorrhea (55.9%). The mean temperature was $38.75^{\circ}C$ and the attack rate among the recruits was 15.7% (588 out of 3750 recruits), while the mean duration of fever was 2.3 days. The prognosis was generally favorable with supportive care but recurrent fever occurred in 10.1% of the patients within a month. Conclusions: This is the first epidemiological study of an RSV outbreak that developed in a healthy young adult group. In the event of an outbreak of an acute febrile illness of a highly infective nature in facilities used by a young adult group, RSV should be considered among the possible causative agents.

Backgroud and Objectives: Inhalation of foreign bodies in respiratory tract can be fatal to infants and child. After ventilating bronchoscopy technique was widelyused, most of the pediatric airway foreign bodies could be managed effectively. In this study, we aimed to analyze clinicalfeatures and outcomes of ventilating bronchoscopic removal of pediatric airway foreign bodies. Materials and Methods: One hundred twenty cases of ventilating bronchoscopy for pediatric airway foreign bodies at Seoul National University Hospital for the past 15 years were analyzed retrospectively. Results: In 120 cases, sex ratio (male: female) was 2.2:1 and mean age was 27.0 months. Most frequent type of airway foreign was peanut (60.2%). One hundred thirteen patients, in whom a foreign body was confirmed in the airway, were successfully managed by ventilating bronchoscopy. Delayed diagnosis and management made a significantly long postoperative hospital stay. Conclusion: Great care must be given when feeding young children, especially younger than 36 months, with nuts. Early intervention with ventilating bronchoscopy following a clinical suspicion is critical to successful treatment.

Backgrounds/Aims: This study aimed to evaluate clinical application of InnoSEAL Plus (a mussel-inspired catecholamine hemostat) as a new hemostatic material for humans. Methods: Patients treated with topical hemostatic patches after liver resection were enrolled. They were divided into an experimental group (InnoSEAL Plus group) and two control groups (TachoSil^® group and Surgicel Fibrillar^® group) for efficacy evaluation. Results: A total of 15 patients were enrolled. Each group had five patients. The 3-minute hemostasis success rate was 80.0% (4/5 patients) in the InnoSEAL Plus group, 80.0% (4/5 patients) in the TachoSil^® group, and 40.0% (2/5 patients) in the Surgicel Fibrillar^® group, showing no significant difference in the success rate among these groups (p > 0.05). All three groups exhibited 100% success rate for 10-minute hemostasis. Both InnoSEAL Plus and TachoSil^® groups had one patient developing adverse events, which were treated easily with drug administrations. Conclusions: InnoSEAL Plus is expected to be functionally not inferior to other conventional hemostatic agents. However, it is necessary to confirm this through multicenter prospective studies in the future.
