Due to poor linguistic communication skills of sucklings and infants, crying mostly is only means of communication to express their body conditions and desires. We, therefore, developed an infant auscultation system which detects which part of the body has a pathological problem, by analysing infant's crying sound patterns. Specifically, in this paper, we accomplished an auscultation system for congenital heart diseases detection by performing pitch, intensity and spectrum analysis of the crying sounds between the normal infants group and the congenital heart diseases group. With this system, we can diagnose congenital heart diseases of infants with poor communication capacity, and, in the near future, can build a home care diagnosis system based on crying sound analysis technologies through additional experiments on medical data.

This study seeks to examine current status and issues on primary education environment and teachers in Cambodia, a country that has a poor education environment and low educational achievement I analysed the features and limitation of education. Major findings revealed the primary school students' low accessibility on education and poor competencies and qualification of primary school teachers, which have hindered a quality of education in Cambodia. Central implications were produced to improve the quality of education and training system for primary school teachers. First, sustainability should be embedded from the initial design to the performance evaluation of the projects. Second, we should carry forward a customized training project that can meet the needs of primary school teachers in Cambodia. Third, the Education ODA project should be institutionalized into the national mechanism of the credit accreditation system, including the incentives of participating. Fourth, in-service training should ensure the inclusiveness and accessibility for the disadvantaged in remote areas. Fifth, short-term workshops for teachers should be avoided, but intensive programs including mentoring should be expanded. Finally, we should support the establishment of autonomous teacher- learning communities based on school level across the Cambodia, which could establish the social capital of the teaching profession in a long term.

This study suggests a model for building governance system to develop and utilize human resources in Chungnam province. In particular, In the regional level of balanced development of human resources, the study tries to investigate alternatives to utilize regional human resources development by building and using a network between related organizations through their partnership and cooperative relations. This survey was conducted to 250 of personnel and experts who were in charge of human resources in diverse chungnam institutions through mail or e-mail from December in 2008 to February in 2009. As a result of the survey, the study shows that basic groundwork for the regional human resources development is poor in terms of forming the system and its plans, and the ties and cooperation between related organization, Therefore this study shows that in order to overcome the current situation and build the governance appropriate to Chungnam area, we need to consider different approaches for each regional organization stage by stage regarding the maturity in the governance.

We study the effect of the high-skilled emigration rate on the growth rate of the source countries. We incorporate the foreign direct investment and the policy variables into the panel model and also their interactions with the high-skilled emigration rate, as they are related to the network externality that may be created by the high-skilled emigrants working abroad. We apply the static fixed-effects model and compare it with the results obtained in the dynamic panel model with system generalized methods of moments estimators. We find the negative effect of the high-skilled emigration rate by itself and in its interaction with the foreign direct investment only in the dynamic model. However, we find positive coefficient for the interaction of the high-skilled emigration rate and the civil liberties index, which holds across the static and dynamic specifications. This implies that the effect of the high-skilled emigration rate on the growth rate of the source countries can be positive, and the extent is larger for countries with 'poor' civil liberties. The developing countries with low levels of foreign direct investment inflows and 'poor' civil liberties can best benefit from the high levels of skilled emigration outward. Through finding significant interactions with other variables, we confirm that the high-skilled emigration should be considered along with other related variables in measuring its impact on growth. The implications offer suggestions for the international trade and aid policies.

Scientific and technological performances (e.g., patents and publications) made through R&D play a pivotal role for national economic growth. National governments encourage academia-industry cooperation and thereby pursue continuous development of science technology and innovation. Increasing R&D-related investments and manpower are crucial for national industrial development, but evidence of poor performance in business performance, efficiency, and effectiveness has recently been found in Korea. This study evaluates performance efficiency of the 6T sector (Information Technology, Bio Technology, Nano Technology, Space Technology, Environment Technology, Culture Technology), which is considered a high-potential promising industry for the next generation growth and currently occupies two thirds of the national R&D projects. The study measures the relative efficiency of R&D in a comparative perspective by employing the Data Envelopment Analysis (DEA) method. The result reveals overall low efficiency in basic R&D (0.2112), applied R&D (0.2083), development R&D (0.2638), and others (0.0641), confirming that economic performance and efficiency were relatively poor compared to production efficiency. Efficient R&D needs policy makers to create strategies that can increase overall efficiency by improving productivity performance and quality while increasing economic performance.

This study was conducted to determine the association between quality of sleep (QOL) and the general characteristics, the health-behavioral factors, and the occupational characteristics of firefighting officers. The survey was conducted in October 2016 with a self-administered questionnaire using the Pittsburgh Sleep Quality Index (PSQI) developed by Pittsburgh University, targeting 600 male firefighting officers working at five fire stations in D city. As a result, the QOL of the study subjects measured by the PSQI revealed 13.2% to be good, and 86.8% to be poor. In relation to general characteristics and health habits, the rate of the group who had poor quality sleep was significantly higher in those with a lower subjective health status, in the non-smoking group, and in the low sleep-quality group, compared to the good sleep-quality group. For occupational characteristics, the rate of those with poor quality sleep was significantly higher in groups such as the fire suppression group, the shift work group, the hard physical labor group, the group with a lower sense of satisfaction in their work, and in the group classed as unfit for the job but who were not considering quitting their jobs, compared to their respective counterparts. Multiple regression analysis revealed factors of influence with explanatory powers of 24.4% for subjective health status, alcohol use, subjective quality of sleep, career, job position, and physical labor. The results of this study suggest that the quality of sleep for firefighting officers is significantly related to general characteristics, health-behavioral characteristics, and occupational characteristics.

The study is to examine the actual conditions and problems of educational welfare which is a part of social welfare and to offer its future directions and things to do. First of all, education has been considered to be part of social welfare in developed countries for a long time and it has been used the same as school educational welfare. These days Korea is confronted with increasing needs of educational welfare caused by emphasis of manpower, appearance of new poor class after IMF, handing down poverty to their children, absence of public education and educational fever, stress of life long learning and extending needs of students' social welfare service. In advanced countries compared to Korea, people perceive education as an equal opportunity. To reach this thesis, various efforts have been making in terms of manpower development such as reform of related laws, financial and official support, offering of parental skills and protecting children for the disadvantaged, dispatching school social workers and overall life improvement. The subjects and age of educational welfare are also diverse ranging from poor families and pre school children to general public and adults. On the other hand, Korea lacks related laws and financial support that are supposed to enforce educational welfare systematically. Also integrated and professional services are not often available due to the lack of cooperation between related agencies. Therefore, government's role and responsibility should be defined clearly in the future directions of educational welfare in Korea. For this, it is needed to establish related laws and build a concrete financial and executive interrelationship. Also every person should be a target of educational welfare putting priorities on the disadvantaged. A lot of efforts should be made to achieve things mentioned above. Multi-dimensional approach intertwined with education, welfare and labour, establishment of cooperation system between related agencies, reinforcement of life long learning, extension of free education including infants and toddlers, and offering financial support to the poor are a few among these efforts. Finally, institutionalization of school social welfare and improvement school facilities are strongly recommended to get to the right track of educational welfare.

The purpose of this study is to examine how area characteristics influence the health of a population in a particular area by investigating how area deprivation and social capital influence self-rated health. For this study, a multi-level logistic regression was employed to analyze the data collected by Community Health Survey conducted on a target population of 229,186 living at 253 administrative areas of Korea in 2011. First, an analysis was conducted for subjects who have rated their self-health assessment as 'fair', 'poor', and 'very poor' in a 5 -item response survey. Then, a second analysis was conducted for the same subjects by excluding those with a rating of 'fair'. As a result, we found that area deprivation significantly influenced the population's health, according to our second analysis, while it was not significant according to our first analysis. Moreover, social capital was not significant in both analyses. Area deprivation-although the value of it was not so high-seems to explain the differences of individual self-rated health assessment as a contextual effect. In addition, influence of area characteristics is not limited to certain local areas, but to all local areas of Korea. Therefore, it is suggested that efforts to improve area characteristics are necessary to upgrade the individual's health level. A standardized classification system-distinguishing between good and poor self-rated health-is necessary through further comparative studies on self-rated health assessment.

The rapid formation of a cream line cannot be observed in raw goat's milk standing at a low temperature. Although the poor creaming ability of goat's milk has been considered to be due to the small size of milk fat globules and the lack of euglobulin capable of being adsorbed on milk fat globules, there is much left to study. The present work attempted to elucidate a factor for poor creaming ability of goat's milk. The creaming ability of the experimental milks reconstituted from creams and skim milks separated from cow's milk or goat's milk was measured by the volume of the cream layer and the fat content of bottom layer. The polypeptides composition of the P1 the fraction (i.e., the high molecular weight fraction eluted near the void volume obtained by the gel filtration of whey) and milk fat globule membrane prepared from both milks were compared. It was found that the promotion of creaming originated from goat's skim milk was lower than that from cow's skim milk. The P1 fraction in goat's skim milk was less than that in cow's skim milk. The polypeptide (M.W. $4.3{\times}10^4$), found in the P1 fraction of cow's milk was not found in the P1 fraction of goat's milk. It is suggested that the poor creaming ability of goat milk is caused mainly by the difference from cow milk in the amount and the composition of the P1 fraction.

This paper is focused on the e-business level in Kangwon Province by industries, volumes, employees comparing with nation wide survey output, and analysis of the tasks and problems of e-business in environment, infrastructure, process, manpower, effect. Poor level of Kangwon province was identified. It is important that role clarity and cooperation among central goverment, Kangwon province, large enterprises and small and medium enterprises. Local goverment and regional cities and counties should play a centripetal role of the regional enterprises, and faithfully execute the support policies of the central goverment, and make the unique supporting climate of coopration between the university and enterprises in consideration with situations of each regional characteristics. More specifically, there are widening the infrastructure of e-business for regional enterprises, strenthening educatin and public relation of the electronic commerce, supporting and utilizing the electronic ccommerce research center. Also, fund supporting for SOHO is desirable in consideration of the poor Kangwon land and population, and to enhence the electronic commerce technology of the Kangwon enterprises, relative importance of policy of it is incresing. In conclusion, indices of Kangwon province in all areas of the survey is appeared poor. So efficient and effective policies is needed in each central and regional goverment. To promote Kangwon enterprises, investment in e-business commerce should be expanded.
