The research aims to investigate the impact levels of determinants on the loyalty of accountants to FDI firms underlying investment management in Thanglong Industrial Park in Hanoi, Vietnam. We conducted a questionnaire consisting of 31 observation variables with a 5-point Likert scale. Independent variables were measured from 1 "without effect" to 5 "strongly". The method of data collection was done through the survey and subjects are accountants in FDI firms doing business in Thanglong Industrial Park in Hanoi. After checking the information on the votes, there are 120 questionnaires with full information for data entry and analysis, This study employs Cronbach"s Alpha test, and regression model. The results show that seven determinants including Working environment, The characteristics of working; Training, promotion prospects and development; Income, Personal characteristic, Collective work together and The method of leading had positive relationships with the loyalty of accountants. Based on the findings, some recommendations are given related to such determinants to improve the loyalty of accountants of FDI firms in general and FDI firms in Thanglong Industrial Park in Hanoi in particular. With which, those firms can enhance performance, reduce financial strain, saving on investment in the recruiting process of new staff, increase profitability to ensure investment management.

Objective: To determine some causes and affecting factors of tubal-peritoneal infertility. To assess the efficacy of laparoscopy in treating tubal-peritoneal infertility. Methods: Prospective study in 126 patients with tubal-peritoneal infertility. Results: Main causes of tubal infertility: Infection: 42.7%, history of operation: 25.6%, endometriosis: 12.8% and other causes and undetermined causes: 18.9%. 79.5% patients have patent tubes through hysterosalpingography. The rate of false obstructed tube through hysterosalpingography was 7.1%. The rate of intrauterine pregnancy after laparoscopy was 21.4%. This rate was associated with the stage of tubal lesons and the highest rate was in the first stage (68.0%). Nobody can get pregnant with the tubal lesions in the third and fourth stage or severe adheson. Conclusion: Main causes of tubal infertility are infection, history of operation and endometriosis. The rate of intrauterine pregnancy and patent tubes in this study is equivalent to some national and international studies. This rate is associated with the stage of tubal le-sions and the degree of tubal adhesion.

Objective: Screening preeclampsia at 11+0-13+6 gestational by combine maternal characteristics, MAP, PAPP-A and UtA-PI. Materials and methods: Prospective screening study for preeclampsia in pregnant attending their first hospital visit at 11-13 weeks 6 of gestation. The performance of screening for PE and GH by combinations of maternal characteristics, uterine artery with the lowest pulsatility index (L-PI), mean arterial pressure (MAP) and serum PAPP-A was determined. Results: Of 2,998 patients with complete outcome data, there were 3.74% of hypertension disorder, and 2.84% cases of pre-eclampsia. The study show a poor results screening for PE by maternal factors only. In screening for PE by combine maternal factors, MAP and L-PI, the estimated detection rates were 18,2% and 45,5% for HG, 45,6% and 57,9% for late PE at a fixed false positive rate of 5% and 10%, respectively.For early PE, in screening by combine maternal characteristics, L-PI, MAP and serum PAPP-A, the the estimated detection rates were 81,8% and 90,9% at at a fixed false positive rate of 5% and 10%, respectively. Conclusion: Effective prediction of early PE can be achieved at 11–13+6 weeks’ gestation by combine maternal characteristics, L-PI, MAP and serum PAPP-A. Key words: preeclampsia; gestational hypertension; screening; PAPP-A, UtA-PI, MAP

Objective: Design an “in house” software for screening preeclampsia by maternal factors and mean arterial pressure at 11 – 13 gestational weeks in commune health centers. Methods: Based on the algorithms for calculating the risk of preeclampsia (PE) by maternal factors and mean artirial pressure at 11 - 13 gestational weeks in the study results of the authors, an “in house” software was deigned in Excel. The results of prediction preeclampsia by The Fetal Medicine Foundation (FMF)(version 2.3) were compared with the results by “in house” software in 1110 singleton pregnant women. Results: The “in house” software met the requirements for calculating the risks of PE and save data. FMF risk for gestational hypertension disorder in pregnancy by maternal factors, mean arterial pressure,uterine artery Doppler and PAPP-A has an area under the curve of 0.68 (95%CI: 0.59 – 0.78). The “in house” software risk for gestational hypertension in pregnancy by maternal factors, mean arterial pressure has an area under the curve of 0.643 (0.55 – 0.73) There was no statistically significant different between two programs (p:0.52). The risk cut-off 1:50 in the prediction of gestational hypertension of the “in house” software was used to identify the group of high risk with detetion rate (DR) 28.6% (95%CI: 14.9-42.2) comparing to 40.5% (95%CI:25.6-55.3) of FMF. Conclusion: The FMF version 2.3 is better but in the absence of Doppler ultrasound and PAPP-A test in the commune health cares, the “in house” software for screening PE is a good tool for councelling, following up and early intervention for PE.
