The incidence of acute pancreatitis (AP) has increased in the pediatric population over the past few decades and it stands to follow that the complications of severe AP, including symptomatic pancreatic fluid collections (PFCs) will increase as well. In adults, the therapeutic options for this situation have undergone a dramatic evolution from mainly surgical approaches to less invasive endoscopic approaches, mainly endoscopic ultrasound-guided transmural drainage (EUS-TD) followed be direct endoscopic necrosectomy if needed. This has proven safe and effective in adults; however, this approach has not been well studied or reported in pediatric populations. Here we demonstrate that EUS-TD seems to offer a safe, efficacious and minimally invasive approach to the management of large PFCs in pediatric patients by reviewing two representative cases at our institution.

This experiment was conducted to establish the cultural practice for reduction of lodging by the effective water management under direct seeding on flooded paddy surface as treated by the drainage times using Dongjinbyeo at National Honam Agricultural Experiment Station during 1994-1995. As the increased midsummer drainage times, the field lodging were reduced by reduction of culm length and large amounts of root with favorable distribution in deep soil, indicating low canopy architecture could promote the light transmission in the plants and favorable root growth. The yield performance was high by increased drainage times which contributed to mainly percentage of ripened grain and 1, 000-grain weight. As a result, two to three times midsummer drainage as effective water management during plant growth was desirable.

In this report, we present a scalp defect reconstruction with lateral arm free flap. We highlight the difficulty in obtaining a recipient vein and the venous drainage managed through an open end of the donor vein. A 52-year-old woman presented with a pressure sore on the left scalp. A lateral arm free flap was transferred to cover this $8{\times}6cm$ defect. The arterial anastomosis was successful, but no recipient vein could be identified within the wound bed. Instead, we used a donor venous end for the direct open venous drainage. In order to keep this exposed venous end patent, we applied heparin-soaked gauze dressing to the wound. Also, the vein end was mechanically dilated and irrigated with heparin solution at two hour intervals. Along with fluid management and blood transfusion, this management was continued for the five days after the operation. The flap survived well without any complication. Through this case, we were able to demonstrate that venous congestion can be avoided by drainage of the venous blood through an open vessel without the use of leeches.

There are 21 abondoned coal mines drained out mine water in gyeong sang do. We monitored the water quality of 31 mine drainage from 1995. The most of mine drainage was neutral as the average pH was 6.22 and Fe, Mn, Al concentration was below 10mg/L. The result showed the tendency of decreasing of flow and metal concentration. The highest Mn concentration was detected in bonghwa area and the hightest Fe concentration was detected in munkyung area. It means that the water quality is closly related to geological features.

This study examined the damage characteristics through investigation for a total of 10 factors (longitudinal position, crossing position, soil type, collecting well volume, outlet position, water apron material, waterway existence, pipe culvert diameter, pipe culvert gradient, pipe culvert height) affecting outlet damages of forest road cross drainage for forest roads in the Research Forest of Kangwon National University. We predicted outlet damages of forest road cross drainage for forest roads using a discriminant analysis Results showed that longitudinal position, crossing position, soil type and pipe culvert height did not affect damages caused to forest road cross drainage. Most influential factors affecting outlet damages were outlet position, waterway existence, pipe culvert diameter, pipe culvert gradient and collecting well volume, respectively. The discriminant ratio calculated from the developed discriminant function was 68.8% which is reasonably reliable.

Head and neck abscess usually requires hospitalization, intravenous antibiotic therapy, and surgical incision and drainage. Open surgical drainage may result in unsightly scars. We report two cases of a 56-year-old man with a facial abscess and a 47-year-old man with a parotid abscess. The patients were successfully treated with ultrasound-guided angiocatheter irrigation and drainage without scar. Ultrasound-guided angiocatheter irrigation and drainage can be a simple, safe and effective alternative procedure to open surgery in the management of the selected head and neck abscesses.

A sub-structure is uplift if the floating greater than dead load of a structure. When such occasion arise, a structure sustain damage. In general, the measures for floating prevention of structure are a permanent anchor method and a drainage method. The primary construction cost of a permanent anchor method is heavy. And a drainage method is needed maintenance management long term. At this point, the measures for floating prevention of a notion being requires the other days. Therefore, at this study a simple construction and a economic vertical drainage system was developed. The findings be used in the in-situ and gave careful consideration to an application. The result of examination, this system considering a characteristic of coefficient of permeability for the ground controls occurrence of floating despite the water level rise of the ground, which a period of construction get shorter compared with other methods, which understood that measures satisfactory in the financial aspect. Especially, A structure occurring effects of flatting under the course of construction made use of it. As the result of the effect of it was confirmed by construction.

To investigate the effect of the midsummer drainage method on growth and lodging characters, Dongjinbyeo was direct seeded on dry paddy field under 4cm of soil depth at May 1 by seeding machine. Three kind of drainage methods were treated such as, once in 20day, towice in 20, 30 days and 3 times 20, 30, 40 days after flooding. As increase the drainage times, the culm and internode length were shorter, culm wall of 4th internode was thicker, breaking weight was heavier, height of center weight was lower, lodging index was reduced, and dry weight of root was increased. Field lodging occured seriously at none drainage but didn't, with two or three times of drainage. Grain yield was not shown significantly different compared with constant flooding irrespective of midsummer drainage times. Therefore two or three times of midsummer drainage could be recommended as the effective water management for the reduction of lodging occurance in direct seeding culture on dry paddy field.

The first drainage time in a day was controlled for precise irrigation management with low consumption of nutrient solution in tomato perlite bag culture system by measuring water level of drained water in drainage catchment part. This method automatically adjusted the irrigation time under any condition of light, temperature and humidity, resulting in stable water content in substrates. However, it was difficult to keep the time consistent as they were set. It drained with the deviation of 20 min in the treatment in which the first drainage time was set at 10:00 and 50 min in the treatment set at 10:30. The first drainage time was not constant, but the drain occurred stably before noon in the treatment of which irrigation frequency was longer than 30 min. The drainage ratio was better balanced in all the treatments using drainage level sensors than the treatment using time clock for irrigation control. High water and fertilizer efficiencies were obtained. Although the growth, total yield and sugar content were not significantly different between the treatments, fruit weight was higher in the treatments using drainage level sensors than that using timer.

Bile leaks are complications that are much more frequent after a high-grade liver injury than after a low-grade liver injury. In this report, we describe the management of bile leaks that were encountered after angiographic embolization in a 27-year-old man with a high-grade blunt liver injury. He had undergone an abdominal irrigation and drainage with a laparotomy on post-injury day (PID) 16 due to bile peritonitis and continuous bile leaks from percutaneous abdominal drainage. He required three percutaneous drainage procedures for a biloma and liver abscesses in hepatic segments 4, 5 and 8, as well as endoscopic retrograde cholangiopancreatography with biliary stent placement into the intrahepatic biloma via the common bile duct. We detected communication between the biloma and the bilateral intrahepatic duct by using a tubogram. Follow-up abdominal computed tomography on PID 47 showed partial thrombosis of the inferior vena cava at the suprahepatic level, and the patient received anticoagulation therapy with low molecular weight heparin and rivaroxaban. As symptomatic improvement was achieved by using conservative management, the percutaneous drains were removed and the patient was discharged on PID 82.
