Pregnancy and delivery pose a high risk of developing metabolic decompensation in women with defects of ketone body metabolism. In this review, the available reported cases in pregnancy are summarized. It is very important to properly manage women with defects of ketone body metabolism during pregnancy, especially nausea and vomiting in the first trimester of pregnancy, and during labor and delivery. Pregnant women with deficiencies of HMG-CoA lyase or succinyl-CoA:3-ketoacid CoA transferase (SCOT) often experience metabolic decompensations with nausea and vomiting of pregnancy, often requiring hospitalization. For successful delivery and to reduce stresses, vaginal delivery with epidural anesthesia or elective cesarean delivery with epidural or spinal anesthesia are recommended for women with HMG-CoA lyase and SCOT deficiency. In beta-ketothiolase deficiency, four pregnancies in three patients had favorable outcomes without severe metabolic problems.

The process simulations are made on the IGCC power plant using heavy residue oil from refinery process. In order to model combined power block of IGCC, the present study employs the gas turbine of MS7001FA model integrated with ASU (Air Separation Unit), and considers the air extraction from gas turbine and the combustor dilution by returned nitrogen from ASU. The exhaust gas energy of gas turbine is recovered through the bottoming cycle with triple pressure HRSG (Heat Recovery Steam Generator). Clean syngas fuel of the gas turbine is assumed to be produced through Shell gasification of Visbreaker residue oil and Sulfinol-SCOT-Claus gas cleanup processes. The process optimization results show that the best efficiency of IGCC plant is achieved at 20% air extraction condition in the case without nitrogen dilution of gas turbine combustor find at the 40% with nitrogen dilution. Nitrogen dilution of combustor has very favorable and remarkable effect in reducing NOx emission level, while shifting the operation point of gas turbine to near surge point.

정유공장으로부터 발생으로 중잔사유를 이용하는 가스화 복합발전 플랜트에 대한 공정모사를 수행하였고, 공기분리장치의 연계공정 최적화를 통해 IGCC 플랜트이 효율을 극대화하였다. 가스화 복합사이클의 발전계통을 모델링하기 위해, 본 연구는 MS7001FA 가스터빈이 공기분리장치와 연계되어 있고, 공기분리장치를 위한 공기 추출과 공기분리장치로 부터의 질소회석이 이루어진다고 가정하였다. 가스터빈의 폐열은 삼중압력의 폐열회수 증기발생장치로부터 회수하였다. 정유공장 중잔사유는 Shell 가스화 및 Sulfinol-SCOT-Claus 공정을 거쳐, 합성가스 연료를 발생시키는 것으로 가정하였다. 공기분리 장치의 연계 공정 최적 결과는 가스화 복합사이클의 효율이, 질소 회석이 없는 경우와 있는 경우에 대해, 공기추출비 20% 또는 40-60%에서 가장 우수함을 보여주었다.

The electrocardiogram (ECG) and electrolytes were measured to obtain diagnostic data after experimental obstruction of duodenum in 8 dogs. Clinical signs of these appeared lower heart rate, temperatures respiration and blood pressure than signs of preoperation. In changes of electrolytes and acid-base balances, all dogs appeared hyponatremiai hypochloremia, metabolic alkalosis, and increased pHi HCO3, scot in blood, but potassium values appeared to increase in 3 cases fl-inc.) and to decrease in 5 cases (K- dec.) Two of three in K-inc. and three of five in K-dec. died at 60 hrs and 72 hrs after obstruction respectly. In changes of ECGI amplitudes of the K-inc cases appeared high in T wave and low in R wave, but amplitudes of the K-dec cases appeared low T waver 57 segment and high in R wave. Conduction times of the K-inc appeared the shorted PR intervals but the K-dec appeared the prolonged PR interval. The changes of these appeared apparently in lead II.

This paper designed a compact printed meandered scot antenna which to integrate in wireless LAN and proposed a printed dual meandered slot antenna for improving bandwidth. A printed dual meandered slot antenna is calculated by using the mehtod of FDTD. The calculated results showed good agreement with the measured results. As a result of measurement, the bandwidth(VSWR< 2) of single meandered slot antenna is 115 MHz and the bandwidth of dual meandered slot antenna is 164 MHz. The dual meandered slot antenna bandwidth has been improves to that of 43% comparing to single meandered slot antenna.

The effects of total, protopanaxadiol-and protopanaxatriol-saponins on the in vitro activities of several enzymes in rat serum were observed Alkaline phosphatase activity was increased 61 % by total saponin and 46% by protopanaxatriol-saponin, compared to control group. While SCOT activity was slightly decreased by total saponin and protopanaxatriol- saponin, it was slightly increased by Protopanaxadiol-saponin And while SCPT activity was slightly decreased by total saponin, it was increased by protopanaxadiol-saponin and protopanaxatriol-saponin. Creatine phosphokinase activity had a tendency to be increased by protopanaxatriol-saponin. Lactate dehydrogenase activities were increased in three saponin treated groups, but those were nonignificant. Compared to the control group, lipase activity was increased by all saponin samples. It was increased 157% by total saponin The increase in lipase activity by total saponin corresponded with the decrease in serum t total lipid by total saponin .

Infection rate of Chrysanthemum stunt viroid (CSVd) in 64 commercial chrysanthemum cultivars cultivated in Korea ranged from 9.7 to 66.8$\%$. Symptoms on leaves of CSVd-infected chrysanthemum included yellow spots, chlorosis, vein clearing, vein bending and crumpling. CSVd induced flower malformation in 'Scot', color change in 'Sharotte', and color breaking in 'Sharon'. CSVd caused reduction of plant height, leaf size, flower size and the flowers number by $32-50\%,\;26-35\%$, $14-36\%\;and\;14-75\%$, respectively. In conclusion, CSVd affected plant height, leaf size and flower quality in chrysanthemum plants.

Welcome to Gemini! In this overview, I'll describe the governance, operations, and capabilities of the Gemini telescopes. I'll also describe Gemini's vision and plans for the future. Gemini is very adaptable and has multiple ways to apply for time, multiple ways to collect your data, and multiple instrument capabilities ready for your observations. Gemini also runs a wide-reaching program to develop and improve our instrumentation capabilities. We run an upgrade program for our existing instruments that includes an annual public call for proposals, a visitor instrument program that brings instruments like IGRINS to our telescopes for short to semi-permanent runs, and a facility program that provides entirely new instruments like GHOST and SCORPIO to Gemini for full public use. Through these programs, you can interact with Gemini in a number of ways to support your scientific needs in the most efficient way possible.

Purpose: 3HB and AcAc are two ketone bodies that can be used as energy source in brain via succinyl-CoA:3-ketoacid CoA transferase (SCOT) and mitochondrial acetoacetyl-CoA thiolase (beta-ketothiolase, T2), called ketolysis. In case of malfunction of these enzymes, ketolysis cannot occur fluently causing various clinical manifestations. We want to know the numbers of patients and clinical manifestations of ketolytic defects in Korea. Material: For 67 patients of ketolytic defects out of 2794 patients that have done urine organic acid analysis, we analyzed clinical manifestations and age distribution. The study period was from January 2007 to September 2015. Method: To confirm persistency of ketonuria, repeated and loading organic acid analysis were done at least 1 week period interval. SPSS was used for statistical analysis. Result: Thirty patients in infantile period (2 M-2 Y), 31 patients in childhood period (2 Y-12 Y), 5 patients after adolescent period (>12 Y) and 1 in neonatal period were diagnosed during the study period. The most frequent chief complaint was seizure followed by seizure with developmental delay and developmental delay only. Conclusion: Ketolytic defects were not so rare in Korea. Major clinical manifestations are seizure and developmental delay or mental retardation.
