Purpose: This study used a descriptive investigative design to identify educational needs for developmental supportive care for the purpose of establishing a developmental supportive care education program for nurses in neonatal intensive care units. Methods: A survey was conducted on 93 nurses working in neonatal intensive care units located in a metropolitan area, and the collected data were analyzed using descriptive statistics and a paired t-test with the SPSS 25.0 program. For the purpose of analyzing educational needs, we further analyzed data through an importance-performance analysis (IPA) and the Borich needs assessment and the locus for focus models. Results: The average importance of the developmental supportive care of nurses in neonatal intensive care units was 3.74±0.78 out of 5, and the average performance was 3.46±0.81 out of 5. A t-test on the difference between the IPA and Borich needs assessment showed the highest educational need in the categories of 'individualized care', and 'I serve on the Developmental Care Committee at my institution'. In addition, according to the results of deriving the priorities of educational needs using the Borich needs assessment and the locus for focus model, the highest priority was 'I provide appropriate pain management when noxious procedures are necessary'. Conclusion: These findings can be used as basic data to design a developmental supportive care program suitable for nurses in neonatal intensive care units to meet the educational needs for developmental supportive care.

The growth kinetics of phototrophic microorganisms can be controlled by the light irradiance, the concentration of an inorganic nutrient, or both. A multi-component kinetic model is proposed and tested in novel batch experiments that allow the kinetic parameters for each factor to be estimated independently. For the cyanobacterium Synechocystis sp. PCC6803, the estimated parameters are maximum specific growth rate $({\mu}_{max})=2.8/d$, half-maximum-rate light irradiance $(K_L)=11W/m^2$, half-inhibition-rate light irradiance $(K_{L,I})=39W/m^2$, and half-maximum-rate concentration for inorganic carbon $(K_{S,Ci})=0.5mgC/L$, half-maximum-rate concentration for inorganic nitrogen $(K_{S,Ni})=1.4mgN/L$, and half-maximum-rate concentration for inorganic phosphorus $(K_{S,Pi})=0.06mgP/L$. Compared to other phototrophs having ${\mu}max$ estimates, PCC6803 is a fast-growing r-strategist relying on reaction rate. Its half-maximum-rate and half-inhibition rate values identify the ranges of light irradiance and nutrient concentrations that PCC6803 needs to achieve a high specific growth rate to be a sustainable bioenergy source. To gain the advantages of its high maximum specific growth rate, PCC6803 needs to have moderate light illumination ($7-62W/m^2$ for ${\mu}_{syn}{\geq}1/d$) and relatively high nutrient concentrations: $N_i{\geq}2.3 mgN/L$, $P_i{\geq}0.1mgP/L$, and $C_i{\geq}1.0mgC/L$.

Contact fatigue damages on the rail surface, such as head checks and squats are a growing problem. The fatigue cracks forming on the contact surface grow according to load and lubricating conditions and may end up breaking the rail. Rail fracture can be avoided by preventing the cracks from reaching the critical length. Therefore, the crack growth rate needs to be estimated precisely according to the conditions of the track and load to develop a maintenance plan against rail damages. Therefore, it is important to understand the mechanism of cracks initiation and growth on a rail due to repetitive rolling contact. In this study, we have investigated the crack growth behavior on the rail surface by using the twin-disc tests and the finite element analysis.

The water quality in the rural areas is degrading due to a variety of causes such as the increase of the urban sewage and industrial wastes, the disposal of solid wastes, the growth of livestock waste, the growth of leisure facilities, the establishment of agricultural industry estates and etc. The water pollutants are scarce while the effluent is increasing from wide scattered sources. The technology specifically designed for the rural wastes water treatment plant needs to be implemented with improvement of agricultural water quality. 1. An integrated management measures against water pollution sources. The prevention of water pollution is the best measures in the environmental pollution. Hence, the most effective measures needs to be against the sources. Small-scale water treatment plants needs to be constructed in each village in the rural areas. As for the industrial effluent, the effluent discharge needs to be strictly monitored. Government subsidy for the establishment of treatment plant for livestock wastes is necessary. 2. The establishment of national-wide network for agricultural water quality. The network for agricultural water quality have been operated to conserve the agricultural water quality, and to develop management policies by the assessment of water pollution in the rural areas. The results of agricultural water quality network indicates that the water quality is degrading not only around urban areas but also in the distant rural areas, and the water quality at the pumping stations and weirs is worse than that of reservoirs. 3. The legal, systematic, and technical approaches for the agricultural water quality management. The actions currently implemented for the improvement of agricultural water quality involve temporary measures such as the improvement of irrigation facilities. These contingency measures are not effective in the long-term, and sometimes bring secondary pollution. Therefore, integrated measures covering the whole water environment such as the flow, quality, river morphology, aquatic ecosystem, and the surrounding environment, need be invented and implemented. Besides, the legal, systematic, and technical frameworks for the management are not fully established so far. The technology for the treatment of rural water pollution should be refined afterwards, and the research for the development of rural waste water treatment plant should be carried out.

Government expenditure on education has attracted much attention because it plays an important role in the economic development. The question is whether government expenditure on education has a positive or negative impact on the economic growth and vice versa. This study aims to provide reliable estimates of the relationship between government expenditure on education and economic growth with empirical evidence in Vietnam for the period 2006-2019. The data was taken from the official statistics of the General Statistics Office of Vietnam. The authors have used the VAR model and Granger causal model to determine the relationship between government expenditure on education and the economic growth. Research results show that there is a two-way nexus between the economic growth and government spending on education with a lag of about two years. From the results obtained from this research, the authors have made some policy suggestions for the Vietnamese government as how to increase investment for education. If there is a one-way causal relationship between expenditure on education and the economic growth, the government can use spending as a growth factor. However, if there is a bi-directional relationship between the government expenditure on education and the GDP growth, the government needs to ensure that resources are appropriately managed and allocated effectively to promote growth.

Economic growth is one of the significant benchmarks determining a country's sustainable growth. Before WWII, most countries perceived their priority in terms of military strength as they dedicated most of their efforts and resources to creating weapons of mass destruction. The current research aims to establish some of the significant factors that may have contributed to the sustainable and progressive economic growth of South Korea within the 60-year timeframe. Multiple prior studies have attributed the economic growth in South Korea to policy reforms that opened the country to foreign markets. The outstanding increase in the percentage of exports stands out as an indication of the improvement in the quality of goods produced in the country. Finally, in recent years, China has dedicated more resources to research and developments as a strategy to improve innovation within the country and its overall economic growth. Other issues of concern likely to undermine the prospects of the country's economic growth include the limited geographical size, aging population, and limited natural resources. As such, South Korea needs to emphasize innovation and improve the business environment as its main strategy for sustainable economic growth in the future to maintain its continuous economic miracle.

Since my arrival on March 15, 1986 I can only give an overview of several topics which I think might stimulate ideas and questions from the members of this technical organization. These topics will include some thoughts about the Korean automotive industry, future needs regarding manpower and cooperation among manufacturers, the oil industry and the government. Korea is experiencing a tremendous growth not only in the export market but also in domestic sales of motor vehicles. This expansion will require trained manpower in many areas of expertise. This growth in technology and manpower will require a great degree of coordination and cooperation between companies and government to reduce duplication, minimize costs and reduce reliance on foreign technology.

The purpose of this study was to find educational needs of toddler's mother in child-caring experience. The subject of the study was toddler's mother who visited one health care center in J city for immunization and had a child or children between twelve and thirty six months old. The subjects were 37 mothers. The instrument used for this study was a semi -structured questionnaire developed by researcher and based on Objective Content Test of Garretson(1967). The collected data were analized by two researchers using the method of Content Analysis. The results of this study are summarized as follows : 1) Of the large categories, the need of the highest frequency was 'prevention and management of disease and injury', that of the lowest 'growth and development'. 2) In 'physical care' category, 'care of sleeping' was the highest. In 'nutrition and eating-habitual management' category, 'weaning management' was the highest. In 'prevention and management of disease and injury' category, 'disease management' was the highest. In 'discipline and teaching' category, 'discipline' was the highest. 3) In comparison with preceding references, the educational needs of child-caring which had not been shown in preceding references but had been shown in this study were hair-caring, kind of weaning diet, method of cure and nursing, man agement of deformity, and so on. In conclusion, educational needs of toddler's mother in child-caring experience were matter-of-fact and inclusive. Needs in management of special situation such as disease were higher than usual parenting procedure or method. In addition, there were higher needs in questions happened through child-caring experience or confirmation of procedures practicing now. Then, it is suggested that parent education program should be developed on the basis of educational needs found in this study to be more effective in preparing mother's child-caring.
