In this study, we conducted to select the promising crops for both uses in the bioethanol and forage production in Korea. The result indicated t㏊t Natsukaje (guinea grass), Gwangpyeongok (corn), Jumbo (sorghum×sudangrass hybrid), SS405 (sorghum×sorghum hybrid), Millex32 (pearl millet), Jeju barnyard grass), Alamo (switch grass) and Selection75 (klein grass) showed the production of biomass from the highest to the lowest in order. However, the order of the production of quality forage was, from the highest to the lowest, Natsukaje (guinea grass), Jumbo (sorghum×sudangrass hybrid), SS405 (sorghum×sorghum hybrid), Gwangpyeongok (corn), Millex32 (pearl millet), Selection75 (klein grass), Jeju (barnyard grass), and Alamo (switch grass). We concluded the Natsukaje (guinea grass) was the best bioethanol crop, and also the Natsukaje (guinea grass) was the best for forage production.

To know adaptability and production of silage corn, we studied on paddy field experiment. Heading date of 'Kwangpyongok' and 'P32P75' Hybrids was on 15th July, 14th July respectively. The dry matter yield of 'P32P75' hybrid (20.4ton/㏊) was the highest among 10 hybrids and that of 'Kwangpyongok' hybrid (19.1ton/㏊) showed high in domestic corn hybrids and other characters as like feed vales is almost same in 10 hybrids.

2가지 이상의 채질로 결합된 구조물이 온도 변화를 받으면 열웅력이 발생한다. 이러한 웅력은 재질간의 열 팽창계수가 서로 상이하여 생긴다. 본 논문에서는 균일한 용도변화를 받는 복합 재료로 이루어진 축대칭 원판 (disk) 에 대한 웅력상태를 구하는 공식올 유도하였다. 먼저， 재료역학원리를 이용하여 근사해를 구한 후， Eigenfunction series를 전개하여 탄성학적인 정확해(Exact Solution) 를 구하였다. 또한 정확해는 유한요소 법으로 구한 해와 비교하였다. 상기 근사해로는 연계연에서의 웅력분포를 예측하는 데 어려움이 있었으나， 정 확해는 유한요소법으로 구한 결과와 대체로 일치하고 있어 웅력분포를 충분히 예측할 수 있었다. 따라서， 본 논문에서 구한 정확해 (Exact Solution) 공식은 복합재료로 구성된 구조물의 연계변에서의 응력분포를 결정 하는데 유용하다.

Retroperitoneal fibrosis (RPF) is a rare disease characterized by the presence of retroperitoneal tissue marked by chronic inflammation and prominent fibrosis. A 67-year-old man presented with general weakness and oliguria. Laboratory findings showed blood urea nitrogen 77.7 mg/dL, serum creatinine 9.24 mg/dL, and an IgG4 level within the normal range. Computed tomography (CT) findings showed bilateral hydronephrosis and distal ureteral obstruction due to fibrotic adhesion to a presacral mass. Laparoscopic biopsy was performed. The authors report a case of acute kidney injury caused by non-IgG4 related focal retroperitoneal fibrosis in the pelvis that was successfully treated using prednisolone and tamoxifen… non-IgG4 related focal retroperitoneal fibrosis caused byacute kidney injury.

Micrococcus lutus is common gram-positive aerobic cocci present in soil, water, dust, and the skin of humans and animals. A 72-year-old man was admitted to the hospital with a complaint of abdominal pain and a turbid peritoneal dialysate. He was empirically treated with intraperitoneal (IP) cefazolin and ceftazidime. Seven day after admission, Gaffkya species was identified from the peritoneal effluent. He was treated with same organism one month ago and discharged with the dialysis catheter intact. So, we suspected that organism is true pathogen, and identified M. luteus by culture. We changed the antibiotics to cefoxitin, which were given for the total of 14 days. This is the first report of relapsing peritonitis by M. luteus and successful treatment without catheter removal.

Peritonitis is a common, major complication in continuous ambulatory peritoneal dialysis (CAPD) patients and tuberculous (TB) peritonitis has been reported to constitute 1-2% of all peritonitis cases. In CAPD patients, TB peritonitis is often diagnosed late and has a high mortality rate. In a recent recommendation made regarding the treatment of TB peritonitis, primary removal of a peritoneal dialysis catheter has been advised in addition to anti-TB drugs. Here, we describe two cases of TB peritonitis in CAPD patients successfully treated without peritoneal dialysis catheter removal.
