Between January, 1970 and August, 1989, a total of 81 patients whose age were more than 20 years of life, received total correction for tetralogy of Fallot. This report analyzed 70 patients among them and excluded the remaining 11 patients whose clinical data could not be found. Their mean age was 25.750.39 years[range 20 \ulcorner50]. The clinical manifestations were cyanosis and clubbing [64 pts], frequent URI[40 pts], anoxic spell [19 pts], infective endo-carditis[4 pts], brain abscess[3 pts], pulmonary tuberculosis[3 pts] and CHF, chest tightness, nephrotic syndrome, left hemiplegia, and tamponade. The types of right ventricular outflow tract obstruction were combined[46 pts], pure infundibular [21 pts] and pure valvular[3 pts]. Associated cardiovascular anomalies were PFO [27 pts], ASDi8 pts], LSVC[8 pts], aortic regurgitation [5 pts], right aortic arch, coronary artery anomalies, PDA and dextrocardia. Hospital mortality was 5.7%. The causes of death ware low cardiac output [2 pts], aggravation of CRF[1 pts] and brain damage[1 pts]. There was one late death because of residual intracardiac shunt and congestive heart failure. During the follow-up period, 16 patients were lost and the remaining 49 patients were asymptomatic and leading normal lives. Residual intracardiac shunt was detected in 5 patients with radionuclide single pass study but all of them had Qp / Qs ratio less than 1.5.

This study aims to investigate the effect of polytriazolesulfone(PTS) addition on fracture toughness of diglycidyl ether of bisphenol A(DGEBA) and 4,4'-diaminodiphenylsulfone(DDS). Various amounts of PTS were added to DGEBA/4,4'-DDS in diazide and dialkyne monomer forms and polymerized during the epoxy curing process. Fracture toughness(K1C), tensile properties and thermal stability of the PTS added epoxy resin were evaluated and compared with those of PES, the conventional high Tg toughening agent, added epoxy resin. Fracture toughness of the PTS added epoxy resin was dramatically improved up to 133%, as the amount of PTS added increased, whereas that of the PES added epoxy resin was improved by only 67%. The tensile strength of PTS added DGEBA/4,4'-DDS was similar to the epoxy resin without PTS and tensile modulus was improved by 20%. And thermal stability of the PTS added epoxy resin was improved up to 14%. Therefore, PTS addition to DGEBA/4,4'-DDS, as a toughening agent, is very effective way to improve its fracture toughness without any lowering in other properties.

The ptsH and ptsI genes of Lactococus lactis subsp. lactis ATCC 7962 (L. lactis 7962), encoding the general proteins of phosphotransferase system (PTS) components, HPr and enzyme I, respectively, were cloned and characterized. A 1.3 kb PCR product was obtained using a primer set that was hybridized to the internal region of the L. lactis 7962 pts HI genes and then subcloned into a low-copy number vector, pACYC184. The 5' upstream and 3' downstream region from the 1.3 kb fragment were subsequently clone using the chromosome walking method. The complete ptsHI operon was constructed and the nucleotide sequences determined. Two ORFs corresponding to HPr (88 amino acids) and enzyme I (575 amino acids) were located. The ptsHI genes of L. lactis 7962 showed a very high homology (84-90%) with those genes from other Gram-positive bacteria. A primer extension analysis showed that the transcription started at either one of two adjacent bases upstream of the start codon. Using a Northern analysis, two transcripts were detected; the first, a 0.3 kb transcript corresponding to ptsH and the second, a 2 kb transcript corresponding to ptsH and ptsI. The transcription level of ptsH was higher than that of ptsI. The concentration of the ptsH transcript in cells grown on glucose was similar to that in cells grown on lactose, yet higher than that in cells grown on galactose. The ptsI transcript was scarcely detected in cell grown on lactose or galactose. The ptsI transcript was scarcely detected in cells grown on lactose or galactose. The results of a sequence analysis and Northern blot confirmed that the ptsH and ptsI genes of L. lactis 7962 were arranged in an operon like other known ptsHI genes and the expression of the ptsHI genes was regulated at the transcriptional level in response to the carbon source.

An adaptive sub-optimal method using a preset threshold for combining partial transmit sequence (PTS) of an orthogonal frequency division multiplexing (OFDM) signal is presented. The results show that adaptive sub-optimal method reduces the 0.1% PAP by 3.4dB, while iterative flipping method reduces it by 3dB and PTS reduce it by 4.1dB. The complexity of adaptive sub-optimal method is 2.4% of that of PTS method for M=8.

Escherichia coli의 중요한 sugar 흡수 system인 Phosphoenolpyruvate. carbohydrate phosphotransferase system(PTS)의 주요 구성 enzyme을 만드는 pts operon에는 여러 개의 promoter가 존재하여 어느 환경에서도 적절한 정도의 PTS 활성을 유지하도록 한다. E. coli pts operon의 P1 promoter transcription이 in vitro와 in vivo에서 차이가 나는 원인을 밝히기 위하여 pts promoter activity에 영향을 줄 수도 있는 pts P0 Promoter의 1kbp upstream에서부터 P0와 P1 promoter까지 transcription vector에 cloning하여 in vitro transcription assay를 한 결과, pts promoter의 upstream DNA가 pts P1 promoter의 in vitro transcription에 미치는 영향이 없음을 알 수 있었다. 여러 가지 PTS sugar들을 이용하여 in vivo에서 이들 sugar 들이 pts transcription에 미치는 영향을 cAMP농도 변화와 비교 조사한 바, glucose존재 하에 자랄 때보다 CAMP농도가 높은 mannose나 mannitol 존재 하에 bacteria가 자랄 때 P1b transcription은 증가하나 P0 transcription은 glucose존재 하에 자랄 때 더 높은 결과를 보였다. 이 결과는 P0에 glucose에 의해 induction되는 repressor가 존재하고, P1 에는 glucose. mannose, mannitol에 의해 공통적으로 induction되는 제 2의 repressor가 존재할 것이라는 가능성을 보여주는 것이다.

Teachers' intervention in small groups is a research area that needs more research attention. Ehrenfeld and Horn (2020) identified teachers' group work monitoring routines that consist of four recurrent talk moves: 1) Initiation, 2) Entry, 3) Focus, and 4) Exit. To better understand prospective teachers' (PTs) intervention in small groups in mathematics classrooms, I investigated how PTs' intervention actions and purposes are related to the monitoring routines, particularly, in terms of Focus moves. I analyzed 26 PTs' responses to four written scenarios, each of which depicts interactions among students in a small group. I identified 1) types of PTs' math talk, 2) types of PTs' non-math talk, 3) types of intervention purposes, and 4) patterns of intervention actions and purposes by scenario. This study contributes to understanding PTs' intervention actions and purposes in mathematics instruction.

This is a retrospective analysis of 67 patients with histologically proven invasive carcinoma of uterine cervix treated with surgery followed by adjuvant radiotherapy at Inje University Seoul Paik Hospital between october 1983 and september 1991, Postoperative radiotherapy was carried out in patients with high risks of locoregional recurrence such as positive pelvic lymph node (38 pts), large tumor size more than 3 cm (22 pts), cervical stromal invasion more than 2/3 (46 pts), parametrial involvement (9 pts), positive resection margin (14 pts), endo/myometrial extension (10 pts), and angiolymphatic invasion (13 pts). Stage I A, I B, and IIA were 2 $(3\%),$ 39 $(58.2\%),\;and\;26\;(38.8\%),$ respectively. Median follow-up period was 48 months with ranges from 13 to 115 months. All 67 patients were treated externally with standard pelvic field with radiation dose ranging from 4080 to 6120 cGy in 4~6 weeks period of time. Of these, 45 patients received intracavitary radiotherapy. The overall survival rate and disease free survival rate at 5-year were $88.0\%\;and\;82.1\%,$ respectively. The survival rates by stage were $87.1\%$ in IB and $88.4\%$ in IIA. Local control rate was $80.6\%(58\;pts).$ The treatment failure was noted in 12 of 67 patients $(17.9\%):$ locoregional failure in $7(10.4\%),$ distant metastasis in 3 $(4.5\%),$ and locoregional and distant metastasis in $2(3\%),$ The univariate analysis of prognostic factors disclosed endo/myometrial extension as a significant factor of survival and recurrence $(70.0\%\;vs\;91.1\%\;P<0.05\;&\;30.0\%\;vs\;15.8\%,\;respectively).$ The complication of postoperative radiothrapy was not significant and all patient were well tolerated. In conclusion, postoperative radiotherapy in patients with high risks of locoreginal recurrence is relatively well tolerated and it gives significantly improved survival rate especially in patients with positive lymph nodes, bulky tumor size $(\geqq3\;cm),$ parametrial involvement, cervical stromal invasion more than 2/3, positive resection margin and angiolymphatic invasion.
