This paper describes a modelling method for SCR(selective catalystic reduction) system in refuse incineration plant. We consider the SCR system as a single input and single output system. For modelling the SCR system, an auto regressive exogeneous(ARX) modelling method is used. In this case, we should design the white noise input for modelling and put it on the system as an input$(NH_3)$, and take an outlet NOx as an output. From these two relations, we design the ARX model with 45 second delay time and transform to a discrete system with sampling time of 0.5 second. Using the obtained SCR model, we verify that the outlet NOx is deeply related with stoker`s moving in boiler of refuse incineration plant.

We have treated a case of pseudocyst of transverse mesocolon in 3-year-old male child. Operative findings demonstrated that the pseudocyst originated in the transverse mesocolon, and was not connected to the pancreas. A colonic duplication was found incidentally near the pseudocyst. On microscopic examination, ectopic pancreatic tissue was noted in the transverse mesocolon. This pseudocyst was thought to have originated from the ectopic pancreas of the transverse mesocolon. This is the first reported case of pseudocyst originated from ectopic pancreas of the transverse mesocolon, combined with a colonic duplication. The pathogenesis is discussed.

The economy is advancing at quite a bit is the role of the Distribution Center, a rise is evolving and mullyuryang Any existing storage facilities were not creating added value from contact with the customer service centers play the role. In order to increase its market competitiveness also pl approach to three in order to enforce cost savings and run. But by industry, the goods, operating characteristics of the cooperating in order to differentiate themselves with the operating process of improvement of operating system, including costs and took lots of time of service.Quality is lower ; all were missing. Such logistics centers, standard management model to address a little bit problem with highest academic. I want to try send it to, each product-category's industrial and business forms, standardisation is really a difficult situation, current study is further progress all you if you are The process managed to turn component is sure that we will be able to be judged.

3차 알릴 알코올을 산화하여 ${\alpha},\{\beta}$-불포화카르보닐 화합물을 얻은 일반적인 방법을 검토하였다. 비교적 간단한 화합물의 경우 우수한 수득율로 작용기가 이동된 카르보닐 화합물을 얻을 수 있었다. 따라서 이 반응은 유용한 합성 수단이 될 수 있다. A general synthesis of ${\alpha},\{\beta}$-unsaturated carbonyl compounds has been developed by oxidation of t-allylic alcohols. In simpler system, pyridinium chlorochromate oxidation affords the functionality transposed carbonyls in excellent yields, making the reaction a useful and versatile synthetic method.

Dolastatin 10의 유사체를 합성하기 위한 연구의 일환으로 여러 형태의 펩티드 화합물의 합성 경로를 연구하였다. 유사체의 합성에 사용된 4-amino-3-hydroxy acid는 에폭시 화합물의 아민에 의한 고리열림에 의하여 합성하였다. 이 비단백질 아미노산응로부터 주로 DCC 축합에 의하여 펩티드 화합물을 합성하였다. As a part of synthetic programs aimed at Dolastatin 10 analogues, synthetic pathway toward various peptides were investigated. 4-Amino-3-hydr> Transfer interrupted!nalogues were prepared by ring opening of epoxides with ammonia in MeOH. Several peptides were prepared starting from these unusual amino acids through using mainly DCC coupling.

Strigol은 목화의 뿌리에서 추출된 천연물로서 벼, 옥수수, 사탕수수 등에 기생하는 피류(striga species) 등의 씨앗을 발아시키는데 월등한 효능을 보인다 $(10^{-12} ∼ 10^{-11}M, 80% 발아)$. 그런데 이러한 잡초는 오랜기간(15∼20년) 동안 흙속에서 휴면하고 있기 때문에 이들의 방제가 매우 어렵다. 이들을 방제할 수 있는 제초제 개발을 위해서 여러가지 strigol 유사체들인 3-methyl-4-(2-oxo-3,3a,6,6a-tetrahydro-2H-cyclopenta[b]furan-3-ylidenemethoxy)-but-2-en-4-olide(21), 4-(2-oxo-3,3a,6,6a-tetrahydro-2H-cyclopenta[b]furan-3-ylidenemethoxy)but-2-en-4-oilde(22), 3-methyl-4-(2-oxotetrahydrofuran-3-ylidenemethoxy)-but-2-en-4-olide(23), 4-(2-oxotetrahydrofuran-3-ylidenemethoxy)-but-2-en-4-olide(24)등을 합성하였다. Strigol, a natural product isolated from root exudates of cotton, was found to be an extremely potent seed germination stimulant for the parasitic plant, witchweed. Witchweed seeds can remain dormant in the soil for several years until favorable conditions prevail including exposure to some type of chemical germination stimulant. Several strigol analogues, 3-methyl-4-(2-oxo-3,3a,6,6a-tetrahydro-2H-cyclopenta[b]furan-3-ylidenemethoxy)-but-2-en-4-olide(21), 4-(2-oxo-3,3a,6,6a-tetrahydro-2H-cyclopenta[b]furan-3-ylidenemethoxy)but-2-en-4-oilde(22), 3-methyl-4-(2-oxotetrahydrofuran-3-ylidenemethoxy)-but-2-en-4-olide(23), and 4-(2-oxotetrahydrofuran-3-ylidenemethoxy)-but-2-en-4-olide(24), were synthesized.

Pediatric lymphangioma can occur at any site. However the neck is the most common site. There are two treatment modalities (surgical excision and intralesional injection) for lymphangiomas. But, the treatment guide line for lymphangioma has not been established, yet. The aim of this study is to establish the treatment guide line based on our experience with lymphangiomas. Medical records of 82 cases of lymphangioma were reviewed retrospectively. On MRI (magnetic resonance image) findings, lymphangiomas were divided into 4 groups by the proportion of the cyst bigger than 2 cm in diameter of the tumor; group A-proportion of cyst occupies more than 75%, group B-proportion of the cyst 50~75%, group C-25~50%, and D in less than 25%. All patients were treated with OK-432 intralesional injection as the initial treatment. The effective response rates of OK-432 in group A & B were 88.2% and 88.8%, respectively. Group C response was 38.0% and D only 20.0%. Twenty-three patients received surgical excision. The result of surgical excision was generally satisfactory. Surgical site infection occurred in 1 case and postoperative bleeding in 1 case. Theses results indicate that intralesional injection of OK-432 could be the first line therapy in group A & B. In group C, OK-432 would be better as the first line therapy than surgery. For the group D, surgical excision should be the first line of treatment.
