The role of the psychoemotional stress during gestation in the development of obstetrical and perinatal patology

The complex investigation of the perinatal pathology at acute and c/1,1-onic psyclioemotliional stress dunng gestation has been perf 01 wed. Jt was sliown (by tlie metliod of the retrospective analyses) the inaease in the relat-ive 1-isf of tlie premature delivery (1,4-8,0), severe and mild gestosis (3,0-10,0), placental pathology (2,2-3,3 ), anomalies of delivery (2,0-7,0 ), obstetlical Blending (2,0- 2,8 ), late delivery (2,0-7,0) dunng the acute stress. The relationship between tlie pelinatal patology and gestation term was shown dunng the acute stress. Dm'ing- i-lie clironic stress tlie frequency and seventy of pennatal patliology is dependent upon the type of psyclioemotional reaction on the st-ress. The seventy of patliofog-y is more prominent at decompensated type of psychological reaction t-lian at subcompensated type. Tlie newbom infants of motlias witli psyclioemotional stress recuired long rehabilitation in 39,2-50,0% cases.

Smoking influence on early and late fetal growth

Objectives Smoking during pregnancy is a leading and modifiable risk factor for fetal growth restriction (FGR) and low birthweight (<10th centile). We studied the effects of smoking in the development of early and late FGR or low birthweight, as well as in uteroplacental and fetoplacental hemodynamics of growth-restricted fetuses. Methods Retrospective cohort study of 5,537 consecutive singleton pregnancies delivered at ≤34 + 0 (“early delivery” group, n=95) and >34 + 0 (“late delivery” group, n=5,442) weeks of gestation. Each group was divided into smokers and non-smokers. Prenatal diagnosis of FGR was based on customized fetal growth standards and fetal Doppler, and postnatal birthweight was assessed using the Olsen newborn chart. Results There were 15/95 (15.8%) and 602/5,442 (11.1%) smokers in the early and late delivery groups, respectively. In early deliveries, FGR was diagnosed in 3/15 (20%) of smokers and in 20/80 (25%) of non-smokers (p=0.68). We also found no differences in birthweights and hemodynamics. In late deliveres, FGR was detected in 30/602 (5%) smokers and 64/4,840 (1.3%) non-smokers (p<0.001). Birthweights <3rd centile and <10th centile were more common in smokers vs. non-smokers: 38/602 (6.3%) vs. 87/4,840 (1.8%) and 89/602 (14.8%) vs. 288/4,840 (6%), respectively (all p<0.01). Fetal Doppler of late FGR showed slightly higher umbilical artery resistances in smokers. Conclusions Smoking in pregnancy is associated with FGR, low birthweight and higher umbilical artery Doppler resistances after 34 weeks of gestation, but we could not confirm this association in earlier deliveries.

Factors Causing Delay in Pile Cap Work (Case Study: Trans Studio Mall Makassar Upgrade Project)

Pile cap as an important part used in construction engineering. Construction projects have a completion schedule, and pile caps as part of a construction project must not be delayed. The purpose of this study is to determine the factors that cause delays in Pile cap work. The analysis method to calculate the results of questionnaire distribution is simple correlation analysis. The results of this study indicate that there are seven factors causing delays Pile cap work on the Trans Studio Mall Makassar upgrade project, namely: (1) Lack of manpower, (2) Late delivery of materials, (3) Rainfall intensity factor, (4) Lack of labor expertise, (5) equipment shortage, (6) equipment damage, (7) the factor of the change of design by the owner. From the results of the calculation of the product moment correlation factor of the lack of labor with the Pearson correlation coefficient value of 0.821 has a very strong relationship.

Extraction of underlying factors causing construction projects delay in Nigeria

Purpose This paper aims to establish the most underlying factors causing construction projects delay from the most applicable. Design/methodology/approach The paper conducted survey of experts using systematic review of vast body of literature which revealed 23 common factors affecting construction delay. Consequently, this study carried out reliability analysis, ranking using the significance index measurement of delay parameters (SIDP), correlation analysis and factor analysis. From the result of factor analysis, this study grouped a specific underlying factor into three of the six applicable factors that correlated strongly with construction project delay. Findings The paper finds all factors from the reliability test to be consistent. It suggests project quality control, project schedule/program of work, contractors’ financial difficulties, political influence, site conditions and price fluctuation to be the six most applicable factors for construction project delay, which are in the top 25% according to the SIDP score and at the same time are strongly associated with construction project delay. Research limitations/implications This paper is recommending that prospective research should use a qualitative and inductive approach to investigate whether any new, not previously identified, underlying factors that impact construction projects delay can be discovered as it followed an inductive research approach. Practical implications The paper includes implications for the policymakers in the construction industry in Nigeria to focus on measuring the key suppliers’ delivery performance as late delivery of materials by supplier can result in rescheduling of work activities and extra time or waiting time for construction workers as well as for the management team at site. Also, construction stakeholders in Nigeria are encouraged to leverage the amount of data produced from backlog of project schedules, as-built drawings and models, computer-aided designs (CAD), costs, invoices and employee details, among many others through the aid of state-of-the-art data driven technologies such as artificial intelligence or machine learning to make key business decisions that will help drive further profitability. Furthermore, this study suggests that these stakeholders use climatological data that can be obtained from weather observations to minimize impact of bad weather during construction. Originality/value This paper establishes the three underlying factors (late delivery of materials by supplier, poor decision-making and Inclement or bad weather) causing construction projects delay from the most applicable.

THE EFFECT OF LATE DELIVERY OF PARTS AGAINST SHIP OPERATIONS AT PT. SUMBERBUMI GLOBAL NIAGA

The sea transportation system plays a very important role in a country's economy. but there are still a number of issues that are of concern to commercial companies such as late delivery of spare parts and ship operations that occur at PT. Sumberbumi Global Niaga. Based on these problems the authors also conducted an analysis to determine whether there is an effect of the late delivery of spare parts to the ship's operations. The author uses quantitative research methods. With a total sample of 12 items. In searching for the calculation results the authors conducted several data analyzes with the results of the correlation test of 0.897 (rxy = 0.897) which proved that a positive correlation exists. And while tcount = 6,812 (6,812> 1,812) and fcount = 17.14 (17.14> 4.96), where if tcount> ttable and fcount> ftabel Linear regression equation is Y = A + bX, then there is a significant relationship between variable late delivery of spare parts against ship operations. Therefore, the results of the study showed that the late delivery of spare parts proved to be significant for ship operations at PT. Sumberbumi Global Niaga. The author also explained several solutions, namely by applying additional spare parts or backup. The goal is as an anticipation if there is a lack of supply of ship parts, so that ship operations are not disrupted if there is a lead time on spare parts.

GDSS Prototype Model for Supplier Selection at MDM Cooperative

MDM is a trade cooperative that has a business unit that provides healthy food for consumers around the Andalas University campus. So far, the selection of suppliers who supply goods to stores is only based on the trust of both parties, the principles of mutual acquaintance and kinship. The problems that arise from a process like this are the lack of the right supplier so that goods are not available all the time, relatively higher prices, late delivery and sometimes there are goods with poor quality. Therefore we need a GDSS that is able to overcome these problems. This GDSS helps decision making in determining the right supplier to the stores owned by MDM Cooperative. The methods used are AHP, TOPSIS and BORDA involving six criteria and five tested alternatives. This GDSS also involves three decision makers, namely the head of the cooperative, the deputy and the treasurer. The results of this prototype are able to show the best alternative that is selected based on the ranking results.

Evaluating the challenges and benefits associated with resource planning and leveling in the Kenyan Construction Industry

Resource Planning and Leveling are two critical areas of resource management which need to be implemented by contractors to aid in construction project execution. However, in the process of undertaking these processes in their projects, contractors meet a number of challenges which discourage them from implementing Resource Planning and Leveling. Nonetheless, Resource Planning and Leveling has a number of benefits which may not be known by some contractors. The purpose of this research therefore was to establish and evaluate the challenges and benefits associated with Resource Planning and Leveling. A survey design was adopted by the researcher. A sample of 106 respondents was selected randomly and a response rate of 76% was achieved. Quantitative data was analysed using descriptive statistics and relative importance index analysis while qualitative data was analysed thematically. Contractors were found to experience serious challenges in their quest to execute Resource Planning and Leveling in their projects. The three most pressing challenges experienced by contractors were found to be: project delays (RII=0.8597); technical incompetence (RII=0.8564); materials shortages or late delivery (RII=0.8390). A number of benefits were found to entice contractors to carry out Resource Planning and Leveling in their projects. The three most significant benefits were: establishing plans for material delivery (RII=0.9215); balanced resources, reducing over allocations or overtime (RII=0.9165) and determining or predicts resources needed (RII=0.9139).

Waste analysis of fuselage assembly in panelization group of the 117th NC212i aircraft

Dirgantara Indonesia (PTDI) is the single source producer of the NC212i Aircraft. Almost every Aircraft is delivered to the customer over the deadline date. The existence of waste is believed to be one of causing the late delivery. Based on observations of the 117th NC212i Aircraft assembly line, which is precisely at the fuselage assembly in the paneling group, six wastes are identified: waiting, transportation, overprocessing, inventory, and motion. Waste of overproduction does not occur because PTDI applies MTO (Make to Order) system. These 6 wastes are then processed using Waste Assessment Model (WAM). The ranking result is: first place is 25% for defects, second place is 23% for waiting, third place is 17% for motion, fourth place is 15% for inventory, fifth place is 13% for transportation, sixth place is 8% for overprocessing, and seventh place is 0% for overproduction. Three critical wastes based Pareto principle can be minimized, so the delay of aircraft delivery can be reduced.

14. Remedies of the buyer

This chapter, the mirror image of the previous one, focuses on the remedies of the buyer who either does not receive goods or receives a defective delivery. The topic is relatively straightforward, largely restating principles of the general law of contract in the specialised field of sale of goods. The chapter concentrates on three forms of remedy: (1) damages for non-delivery, late delivery, or breach of warranty, (2) the recovery of money paid for a consideration that has totally failed or been validly rejected, and (3) specific performance and injunctions.
