The launch of a new business is crucial to the future growth and profitability of a company. A new business project typically requires a large amount of resources while it has a high possibility of failure. The evaluation of new business opportunities is therefore quite a critical decision-making to companies. This evaluation includes screening of a large number of criteria at a time which often makes desision-making very complicated. Management should evaluate the business alternatives in a sound and consistent manner that is hard to achieve because the new business evaluation is a typical semi/unstructured decision-making problem. The difficulty in such an evaluation will increase if it is required for management to consider both quantitative and qualitative criteria simultaneously. Under these circumstances, this study has proposed a decision-making framework that utilizes analytical hierarchy process(AHP). This study has identified a set of criteria essential to the new business evaluation and suggested a systematic framework for it. Both qualitative and quantitative evaluations are incorporated into the single framework in this study.

The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

Purpose: The purpose of this study was to evaluate the physical growth and developmental status of infants and children of married immigrant women. Methods: The participants were 92 infants and children aged from birth to 6 yr whose mothers were married immigrant women living in one rural area. Physical growth and developmental status were evaluated by using anthropometric assessment, and Korean Denver II developmental screening test. Results: Of the participants, 10.8% were below the 3rd percentile for weight, 13.0% for length, 5.4% for head circumference, and from 69.6% to 79.3% were distributed below the 50th percentile on growth charts. Further, 18.5% were classified as having questionable development. Factors related to low physical growth in infants and children were mother's weight and mother's level in Korean language classes. Conclusion: The physical growth and developmental status of children is vulnerable and serious. The study results suggest a need for regular growth and developmental evaluations. Political support is important for these mothers. In addition, there also is a need to develop early intervention strategies to promote growth and development of the infants and children of these married immigrant women.

To establish the evaluation of the fatigue crack growth behavior in 5083-O aluminum alloy, constant load-amplitude fatigue crack growth tests were carried out under the small scale yielding conditions. Crack length and closure of this material were measured by the compliance method using a clip-on gage. The main results obtained as follows: The fatigue crack growth rate against stress intensity factor range .DELTA.K exhibits the trilinear form with two transitions at the growth rate 5.5*10$^{-6}$ and 5.5*10$^{-5}$ mm/cycle, in the so-caled Region II. The trilinear form appears still in the plot of growth rate versus effective stress intensity factor range .DELTA. $K_{eff}$. Stress ratio R affects the relationship of crack growth rates versus .DELTA.K but does not affect the reation of crack growth rate versus .DELTA. $K_{eff}$. The experimental results indicate that the effective stress intensity range ratio U depends on the maximum stress intensity factor $K_{max}$, but not on the stress ratio R.o R.R.

Purpose: There has been a consistent failure of businesses that are run by a single person. Most of these collapse at infancy prematurely and those that survive continue to operate at minimal capacity. The study thus sought to enhance growth of sole proprietors from being small entities to large corporates. Financial determinants of business growth were earmarked for research as they were amongst the grey areas of business growth research. Research design, data and methodology: The target population of the study was made up of groceries retail sole proprietors operating in Epworth, Zimbabwe. Questionnaires were used in a once-off cross-sectional survey using stratified random sampling. Through a deductive research approach, four financial determinants of business growth were established namely financial availability, financial management, financial evaluation and financial investment (AMEI). These constructs formulated the basis for the development of the model which linked financial factors to business growth. Results: The study found out that all four financial determinants were statistically significant (P < 0.05) in predicting business growth. Conclusions: The study concludes that the model tested was useful in explaining sole proprietor's business growth. Sole proprietors should have access to funding, manage received funds in an appropriate manner, invest into the business and evaluate their business processes.

Emerging medical technologies for effective and lasting repair of articular cartilage include delivery of cells or cell-seeded scaffolds to a defective site to initiate de novo tissue regeneration. In this respect. the availability of an appropriate biomaterial scaffold is crucial to allow chondrocyte growth and cartilaginous matrix deposition in a three-dimensional geometry. Hyaluronic acid (HA) molecules are anchored to the chondrocyte membrane via receptors, such as CD44. (omitted)

A feeding trial was conducted in tilapia to determine the growth performance, nutrient digestibility, digestive enzymes, and postprandial blood metabolites in response to different dietary amylose-amylopectin ratios. Five isonitrogenous and isolipidic diets containing an equal starch level with different amylose-amylopectin ratios of 0.11 (diet 1), 0.24 (diet 2), 0.47 (diet 3), 0.76 (diet 4) and 0.98 (diet 5) were formulated using high-amylose corn starch (as the amylose source) and waxy rice (as the amylopectin source). Each diet was hand-fed to six tanks of 15 fish each, three times a day over a 6-wk period. After the growth trial, a postprandial blood metabolic test was carried out. Fish fed diet 2 exhibited the highest percent weight gain and feed efficiency and protein efficiency ratio, whereas fish fed with diet 5 showed the lowest growth and feed utilization among treatments. The digestibility for starch in fish fed diet 1 and 2 was higher than those in fish fed with other diets (p<0.05). The highest activities for protease, lipase and amylase were found in fish fed the diet 2, diet 1, and diet 1 respectively among dietary treatments, while the lowest values for these indexes were observed in fish fed the diet 3, diet 5 and diet 4, respectively. The liver glycogen concentrations in fish fed diets 4 and 5 were found higher than in fish fed other diets (p<0.05). The feeding rate, hepatosomatic index, condition factor, and plasma parmeters (glucose, triglyceride, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol) did not differ across treatments. In terms of postprandial blood responses, peak blood glucose and triglycerides were lower after 3 or 6 h in the fish fed with diets 3-5 than in the fish fed diet 1, but delayed peak blood total amino acid time was observed in fish fed with the diets 1 or 2. The lowest peak values for each of the three blood metabolites were observed in fish fed diet 5. The results indicate that high-dietary amylose-amylopectin ratio could compromise growth, but help in reducing the blood glucose stress on fish caused by postprandial starch load.

This study was carried out to evaluate the plant growth rate according to the wavelength characteristics of LED light sources. In order to achieve this, red, green, blue and white LEDs were arrayed in a rectangle array consisting of LED modules which can be combined with each other.. This can facilitate the selection of the optimal characteristics of the light from monochromatic red, green, blue and white LEDs or mixed LEDs for plant growth. Experiments to evaluate the growth rate according to the wavelength characteristics of the LEDs with several plants, in this case ice plants, lettuce, barley, broccoli and chives, were performed.

In order to assess the validity of fatigue crack arrest design charts obtained from our previous numerical approach to fatigue crack arrest condition, an extensive fatigue crack growth/arrest test was performed using CT-type integrally stiffened panels. The results are presented as fatigue crack growth rate and non-dimensional crack length relationship, and these are compared with numerically simulated crack growth rates. The measured values of da/dN at the moment of fatigue crack arrest occurred in stiffened panels are good agreement with those numerically simulated crack growth rates.

Two medicinal plant of Sundarbans mangrove forest has been tested for the evaluation of growth inhibitory and antibacterial activity. The methanol extract of Xylocarpus granatum stem bark showed potent wheat rootlet ($IC_{50}=0.01{\mu}g/ml$) and shoot ($IC_{50}=0.23{\mu}g/ml$) growth inhibitory activity in a concentration related manner. The growth inhibitory activity was markedly decreased in residual methanol extract. The methanol extract showed antibacterial activity (MIC > 3 mg/ml) against Bacillus subtilis, Staphylococcus aureous and Proteus vulgaris. The residual methanol extract did not show any antibacterial activity. The results suggest the bioactive principle(s) of Xylocarpus granatum may be relatively non polar compound(s). The methanol extract and residual methanol extract of Sarcolobus globosus stem showed poor wheat rootlet and shoot growth inhibitory activity and no antibacterial activity.
