Gastric malignant peripheral nerve sheath tumors (MPNSTs) are extremely rare spindle cell sarcomas that arise within the peripheral nerves of the gastrointestinal tract. MPNST can present as a mass that may or may not be accompanied by obstruction or bleeding. Type 1 neurofibromatosis (NF) is an autosomal dominant genetic disorder with an incidence of 1 in 2,500-3,000. Plexiform neurofibromas in Type 1 NF can undergo a malignant transformation to MPNSTs. Approximately half of the incidence of MPNST is associated with the NF-1 gene. MPNST behaves aggressively, and radical excisional surgery is important for treatment. Recurrence and metastasis are significant, even after a radical excision. Despite multidisciplinary treatment, the five-year survival rate is only 30-50%. This paper reports the case of a 47-year-old man with Type 1 NF who presented with hemorrhage of a gastric subepithelial lesion. He underwent surgery under the suspicion of a gastrointestinal stromal tumor, but it was diagnosed as MPNST after confirming the histopathological appearance and immunohistochemical profiles. In addition, the large mass invaded the spleen and diaphragm. Radical surgery was performed, and additional chemotherapy was administered. This paper reports the experience of a patient with NF 1 with advanced MPNST discovered due to a subepithelial lesion.

Objectives of this study were to propose an optimal fertilization method of Chlorella and to evaluate its effects on growth of green pepper. Chlorella fusca strain was propagated and used in the experiment. As for treatment, drenching method (DM), foliar fertilization (FF), drench and foliar fertilization combination (DM + FF), and untreated control (CO) were used. Plant height of green pepper was higher in the CO treatment than in chlorella fertilized treatments. Chlorella fertilization inhibited stem growth of green pepper. Chlorophyll contents of green pepper leaves were higher in the DM + FF treatment. Yields were the higher in DM and DM + FF treatments than in other treatments. Vitamin C content was the highest in the DM + FF treatment. These results showed that Chlorella fertilization could increase the growth, yield, and bioactive substance content of green pepper. The Chlorella fertilization method could be applied to other crops. By applying this technology to the farmer, it is possible to increase income and supply healthy and safe high-quality agricultural products to consumers. 클로렐라 시비 방법이 풋고추의 생육, 수확량 및 생리활성물질 함량에 미치는 영향을 조사하여 최적 클로렐라 시비법을구명하고자 하였다. 아래와 같은 연구결과는 다른 작물의 클로렐라 시비 시에 적용 가능하며, 농가의 소득 향상뿐만 아니라 소비자에게 건강하고 안전한 고품질의 농산물을 공급하는데 도움이 되리라 생각한다. 풋고추의 초장은 무처리구가 클로렐라 시비 처리구(관주, 엽면, 엽면+관주)보다 더 높았고, 이를 통해 클로렐라 시비가 고추의 도장을 억제하는 것을 확인하였다. 엽록소 함량 분석 실험의 결과 풋고추 엽의 총 엽록소 함량은 엽면+관주 처리구의 함량이 높았으며, 풋고추 생과는 관주처리구의 엽록소 함량이 가장 높은 결과를 보였다. 수확량은 관주시비와 엽면+관주 조합시비 처리구에서 가장높았다. 생리활성물질 함량 분석 결과 비타민C 함량은 엽면+ 관주 조합처리구가 가장 높은 결과를 보였다. 본 연구의 결과 클로렐라를 시비가 풋고추의 생육, 수확량및 생리활성물질 함량을 증가시킨다는 결과를 확인하였다.

The construction debris has been enormously increased since 90's because of a reconstruction and developing a new building site. Under the construction law, construction debris must legally recycle or reclaim at cost, but almost people have depended on reclamation of the illegal process to treat construction debris. Therefore, the environmental disruption and contamination have been begun the hot issue of society and in controversy with residents. With the consequence that indicates a substitute about an application of construction debris units is the most important thing for studying construction debris of quantity when the construction units are demolished. Nowadays, the area under the housing environment amelioration policies is getting rapidly old, then it is beyond anticipating reconstruction. Before construction units are demolished, generally three of four engineers investigate or predict the quantity of construction debris for two months. But this study is using the units of construction debris instead of the investigation and gets more precise data than investigation or prediction. In conclusion, the purpose of this study offers that units of construction debris can alternate the investigating of construction debris and curtail the expenses of labors and finances. Finally, those effects are going to make economical benefits covering the whole of the process of constructions.

The re-determination of safe, initiative and appropriate egress strategies must be essentially treated in the post-9/11 environment, because the current egress strategies cannot guarantee the occupants' safety anymore throughout the evacuating toward inside extraordinary evacuation places such as the refuge floors and rooftops and so on. Hence, the application of simultaneous egress strategy is inevitable for protecting occupants' safety in high-rise buildings, however, the full evacuation time is liable to increase when using the simultaneous egress strategy for escaping building because of overcrowding, bottle-neck, physical fatigue and panic of evacuees and so on. Therefore, this study analyzed to find the appropriate complex egress strategies applied the evacuation elevators for decreasing the full evacuation time of high-rise buildings and also proposed the detailed evacuation elevator criteria of introduction.

광질은 묘의 형태를 조절하는 중요한 환경 요인 중 하나이다. warm-white와 cool-white LED의 칩에 비율이 다른 bar type를 제작하여, 백색 LED의 광질에 따른 묘의 생육을 조사하고자 연구를 수행하였다. 오이, 토마토 및 수박의 접수와 대목의 종자를 파종하여, LED를 광원으로 하는 식물공장에서 재배하였다. 처리구는 W1C0(warm-white 단독), W1C1 (warmwhite: cool-white=1:1), W3C1 (warm-white:cool-white=3:1), W5C2 (warm-white:cool-white=5:2)이다. 모든 처리구에서 W1C1 처리구에서 재배한 묘목의 배축장이 가장 짧았으며, W1C0에서 재배된 묘목의 배축장이 가장 길었다. 수박 접수, 수박 대목, 그리고 토마토 대목의 배축장은 W1C1, W3C1, W5C2, W1C0 순이었으며, 이는 cool-white의 비율이 높은 순서와 같았다. 토마토 접수는 각각 W1C0과 W3C1에서 첫 번째와 두 번째로 배축이 길었고 W5C2와 W1C1에서 가장 짧았으며, 통계적 차이는 없었다. 경경은 토마토 접수, 토마토 대목 및 수박 대목을 제외하고는 큰 차이가 없었다. 토마토 접수, 토마토 대목 및 수박 대목의 줄기 직경은 W1C0에서 가장 굵었다. 오이, 수박의 접수와 대목의 지상부 생체중과 오이 접수의 지하부 생체중은 W1C1에서 가장 작았다. 본 연구를 통해 LED 광원의 다양한 비율은 묘목의 배축 신장에 크게 영향을 미치는 것을 확인하였다. Uniform scions and rootstocks should be produced to ensure grafting success. Light quality is an important environmental factor that regulates seedling growth. The effects of warm- and cool-white light emitting diode (LED) ratios on seedling growth were investigated. Scions and rootstocks of cucumber, tomato, and watermelon were grown in a closed transplant production system using LED as the sole lighting source. The LED treatments were W1C0 (only warm-white), W1C1 (warm-white: cool-white = 1:1), W3C1 (warm-white: cool-white = 3:1), and W5C2 (warm-white: cool-white = 5:2). The seedlings grown in W1C1 had the shortest hypocotyls, and the seedlings grown in W1C0 had the longest hypocotyls among the three tested vegetables. The hypocotyls of watermelon scions, watermelon rootstocks, and tomato rootstocks were shortest in W1C1, followed by those in W3C1, W5C2, and W1C0, but there was no significant difference between W3C1 and W5C2, which remained the same as the ratio of cool-white LEDs increased. In addition, tomato scions had the first and second longest hypocotyls in W1C0 and W3C1, respectively, and the shortest hypocotyls in W5C2 and W1C1, along with W5C2 and W1C1, although the difference was not significant. The stem diameter was highest in W1C0 except for tomato seedlings and rootstocks of watermelon. The shoot fresh weight of scions and rootstocks of cucumber and watermelon and the root fresh weight of cucumber scions were lowest in W1C1. These results indicated that different ratios of LED lighting sources had a strong effect on the hypocotyl elongation of seedlings.
