Earthwork is an essential initial work discipline in construction projects and open to significant impacts of several factors such as weather, site conditions, soil conditions, underground installations and available construction machinery, calling for careful planning by managers. However, selection and combination of construction machinery and equipment for earthwork still depends on experience or intuition of managers in construction sites, with much room left for proper management in terms of cost, schedule and environmental load control. This research aims to analyze the performance of earthwork equipment and establish relations among various factors affecting a model for optimizing selection and combination of earthwork equipment as a precursor to the development of such model. We expect the conclusions herein to contribute to optimizing selection and combination of earthwork equipment and provide basic inputs for the development of applicable model that can save costs, reduce schedule and mitigate environmental load.

This study has been a study on changes seen in rural kitchens and factors affecting the modernization of agrarian kitchen space. The major findings were as follows: 1) The physical changes in kitchen design were carried out rapidly after 1977. This period coincided directly with the period in which kitchen improvement projects were fostered by the Sae Ma-Eul UNDONG 2) The study showed the macro factors contributing to changes in kitchen space to be government policy and industrialization. The study showed the micro factors influening kitchen space changes to be classified along socio-demographic lines and family lifestyle. 3) The factors affecting the degree of satisfaction with kitchens have been divided into socio-demographic and lifestyle characteristics. The level of education achieved by the husband was the most significant among socio-demographic characteristics. Most important among lifestyle characteristics were the cooking fuel used during the slack farm season, eating habits, heating fuel and eating space respectively. The results of this study have some implications in terms of government housing policy. Policymakers should be aware of suitable kitchen spaces to rural households in order to meet their housing needs and expectations.

In order to establish a method predicting susceptible cows to the parturient syndrome, various serum chemical parameters (calcium, phosphorus, Ca/P, magnesium, cholesterol, total protein, albumin, globulin, A/G, total lipid, non-esterified fatty acid(NEFA) and aspartate aminotransferase(AST)) were measured during late pregnancy and their relationships with periparturient diseases were investigated during puerpural period. The results obtained were as follows : 1. The factors affecting the prediction of susceptible cows to parturient syndrome were calcium, magnesium, total protein, globulin, A/G ratio and total lipid at 30 day antepartum and the diagnosability was 70.7%. 2. In the experimental cows producing more than 21kg of milk per day, the factors affecting the prediction of susceptible cows to parturient syndrome were calcium, NEFA and A/G ratio at 30 day antepartum and the diagnosability was 66.7%. 3. In the experimental cows calved more than 3 times, the factors affecting the perdiction of susceptible cows to parturient syndrome were calcium, total protein, albumin and NEFA at 30 day antepartum and the diagnosability was 83.3%.

Although peak loading coefficient is one of critical design factors for sewer works, its detailed affecting factors were not analyzed because of limited data availability. This study analyzed the affecting factors on peak loading coefficient with plenty data obtained from several newly constructed sewer works. Simple and multiple regression analysis methods were adopted to analyze the relationships of each variable with or without data filtering. Drainage population, drainage area, population density, and daily sewage flow per person showed very weak relationships under diverse characteristics of cities. However, daily sewage flow per person showed stronger relationships with peak loading when daily sewage flow per person was splitted into two ranges. Population density (i.e., drainage population divided by drainage area) and daily sewage flow per person considerably were related with peak loading coefficient when daily sewage flow per person is less than about 400 Lpcd.

Investigations into fatty acid composition in meats are becoming more important due to consumer demand for high quality healthy food. Marker-assisted selection has been applied to livestock to improve meat quality by directly selecting animals for favorable alleles that affect economic traits. Quantitative trait loci affecting fatty acid composition in cattle and pigs were investigated, and five candidate genes (ACACA, FASN, SCD, FABPs, and SREBP-1) were significantly associated with fatty acid composition. The information presented here should provide valuable guidelines to detect causative mutations affecting fatty acid composition in cattle and pigs.

Neonates have large inter-individual variability in pharmacokinetic parameters of many drugs due to developmental differences. The aim of this study was to investigate the factors affecting the pharmacokinetic parameters of drugs, which are commonly used in critically ill neonates. Factors that reflect physiologic maturation such as gestational age, postnatal age, postconceptional age, birth weight, and current body weight were correlated with pharmacokinetic parameters in neonates, especially preterm infants. Comorbidity characteristics affecting pharmacokinetics in critically ill neonates were perinatal asphyxia, hypoxic ischemic encephalopathy, patent ductus arteriosus (PDA), and renal dysfunction. Administration of indomethacin or ibuprofen in neonates with PDA was associated with the reduced clearance of renally excreted drugs such as vancomycin and amikacin. Therapeutic hypothermia and extracoporeal membrane oxygenation were influencing factors on pharmacokinetic parameters in critically ill neonates. Dosing adjustment and careful monitoring according to the factors affecting pharmacokinetic variability is required for safe and effective pharmacotherapy in neonatal intensive care unit.
