To achieve the dental health of children and adolescents which is the objective of the pediatric dentistry, the role of the public service should be increased. The basis of the public service is established by many laws of which the Dental Health Law is most important. The percentages of primary schools that had the school dental health clinic, that implemented the fluoride rinsing program, and that implemented the group toothbrushing after lunch were 7.2%, 57.5%, and 46.9%, respectively, and the percentages of primary school children that received the dental health education and that received the fissure sealing were 48.0% and 12.4%, respectively(2006). About 42% of infants and preschool children from 0 to 6 years received preventive dental care in the last one year, at the nursery or kindergarten(18%) or at the health center(1%)(2005). The percentage of the health centers that implemented water fluoridation was 11.3%, and the percentage of the population who drank the fluoridated water was 5.7%(2006). It was suggested that the school dental health administration should be unified, that dental health teachers should be employed, and that the comprehensive dental health care should be supplied to all the children and adolescents through the circuit school dentists and the school dental hospitals in the long term. Also, the dentist in charge system for the children and adolescent was suggested.

Korean ginseng (Panax ginseng C.A. Meyer) is very difficult to obtain stable production of qualified ginseng roots because of variable stresses in soil environments. High salt concentrations in the ginseng nursery soil environment of Korea is one of important reducing factors for the stable production of quality ginseng. These studies were accomplished to identify the growth rate and production of ginsenoside from ginseng hairy root against NaCI. In the MS liquid culture, the highest contents and productivity of ginsenosides were appeared at 4 week after onset of the treatment of 0.1 M NaCI. And 0.24 M NaCI was more effective on the growth of ginseng hairy root under light condition than dark condition. Plants generally produce secondary metabolites in nature as a defense mechanism against pathogenic and insect attack. In this study, NaCI acts as a kind of stress as well as elicitor for production of ginsenosides.

This study was conducted to investigate setting approach of health promotion in Healthy city projects. We used the secondary data of 2008-2010 Healthy city projects, reports, papers, workshops and symposia and had professional meetings to obtain the implications. Setting approach of health promotion in Healthy city projects conducted 27 (14.7%) in 2008 and 42 (21.8%) in 2009. Looking at the type of setting approach, villages and schools, respectively, was the highest (six, 22.2%) in 2008. In 2009, the school was 12 (28.6%), apartment 8 (19.0%), village 6 (14.3%), day nursery 5 (11.9%), workplace and senior center 4, respectively (9.5%), market 3 (7.1%). School and apartment are the most common setting approach in the metropolitan area, but senior center and village are most common in the rural areas. The good examples of health promoting schools, healthy workplaces, healthy villages, healthy apartments, health promoting hospitals, healthy markets, healthy senior centers were examined. To sustain and success the setting approach in health promotion, persons in settings must know the exact meaning of 'setting' and 'health promotion' and the efforts that setting can play an important role in healthy cities (communities) will be required.

This study was conducted to investigate a proper method of ball mark repair by comparing the creeping bentgrass recovery speed on golf course green treated by various methods of ball mark repair. Nine general repairing methods were tested and compared; control (no repair, A type), two common methods of USGA (B type) and GCSAA (C type), three methods with fork shaped hand set performing at Korean golf courses (Ansung Benest, D; Sky72, E; Lakeside, F type), and three methods using the repair machine with 6, 8, or 14 teeth (G, H, I type, respectively). Three creeping bentgrass cultivar of 'Penncross', 'T-1', and 'CY-2' were tested in this field experiment. This test was carried out from September to November in 2009 at the nursery on the Seoul Lakeside Golf course. The average speed of turfgrass recovery after various ball mark repairing methods have been ranked as in the order of E, D, C, B, F, I, H, G, and A. The methods of hand practise showed more effective results than repair method using machines. The ball mark recovery speeds of 'Penncross' were in the order of E, D, B, C, F, I, H, and A. In the case of 'T1' and 'CY-2', similar orders were showed as D, E, B, F, C, H, I, A, G and the order of D, E, C, F, B, H, G, I, A, respectively. The ball mark recovery speed among creeping bentgrass cultivar resulted in the order of 'CY-2', 'Penncross', and 'T-1'. The most proper method of ball mark repair was repair method using a hand set tool especially the method of the Sky72 Golf course (E type). At the first, remove a damaged grass area with fork and tap. And then gather the side grasses into the center area with pulling the grasses with fork. After that, make harden and flat on the turf surface by pounding and rolling with the round wooden stick. The final Nstep, water the repaired grass surface. This ball mark repairing practise showed a most rapid and proper recovery method on creeping bentgrass green.

Various artificial reefs provide the fish habitat and nursery, and contribute the improvement of fisheries productivity. The evaluation methods of fishery resources in the artificial reefs have been done by fishing, scuba diving, underwater camera, and scientific echo sounder/sonar. There are a number of studies using echosounders on the quantitative and qualitative evaluations of artificial reefs in various seas around the world. This study focused on the spatial distribution of fishes around artificial reefs and the influential area of reefs off Bukchon, Jeju Island. Not only acoustic data but also various properties of artificial reefs were used in the geographic information system to extract relevant results. As a result, the major material of reefs on this study site was concrete and the number of reefs with that material was the most. The volume of reefs consisted of steel only and steel with riprap was considerably large compared to other reefs. The average NASC in the vertical distribution of fishes in artificial reefs was $31.6m^2/nm^2$ in April, and that was $61.3m^2/nm^2$ in June. The distance between the fish school and their nearest reef in June morning had a wide range from 750 to 3250 m. On the basis of the influence ray of artificial reefs, it had a tendancy of NASC to decrease with distance from the reef in the June morning. It is a preliminary study to present the geospatial analysis example to understand a better way of comprehensive artificial reef environments.

The study's purpose was to clarify childcare's impact on the psychological well-being of fathers with an infant. This study included 1,250 households that used 15 nursery centers. The questionnaire asked about the fathers' age, income, working conditions, participation in childcare, recognition of sense of usefulness to their family, marital satisfaction, mental health, health-related quality of life(QOL), and the mothers' age, number of children, age of the youngest child, and working conditions. A casual model was examined using SEM. The results were as follows: first, fathers' participation in childcare contributed to health-related QOL through the recognition of feeling useful to their family. Second, fathers' participation in childcare contributed to marital satisfaction, directly and indirectly through health -related QOL and improved mental health. Third, fathers' participation in childcare contributed to health related QOL through the recognition of feelings of usefulness, marital satisfaction, and mental health, indirectly. These results suggest that promoting fathers' participation in childcare is important to help prevent many problems and to improve QOL.

This study was designed to examine the relationships between rough and tumble play and children's social language use. The subjects were 90 children in a nursery school in N city. The data was analyzed using the Pearson correlation and stepwise regression. The results were as follows. First, there was a significant positive relationship between rough and tumble play, and the children's social language use. Second, the children's social language use' sub valuables had an effect on rough and tumble play. In particular, 'demand of action' has negative effects on the 'pull and push', and 'catch'. Furthermore, 'rejection' has negative effects on 'collapse' and 'rush'. This suggests that a rough and tumble play program can be developed to enhance the children's social language use.

The studies have been conducted to control the soil borne fungal pathogens viz, Fusarium solani (Mart) Sacc. and Alternaria tenuissima the incitants of root rot and die-back diseases on mulberry stem cuttings planted in the mulberry nurseries and also in established mulberry gardens ten plant extracts with 10% concentration except Lantana camara (undiluted) were tested through poisoned food technique and four biofungicides were also screened by dual culture method under in vitro conditions. Plant extract of Prosopis juliflora showed the maximum inhibition on the mycelial growth (81.2% over A. tenuissima and 80.0% over F. solani) and followed by L. camara (66.7% over A. tenuissima and 68.9% over F. solani). Among the antagonists Pseudomonas fluorescens and Trichoderma viride showed maximum inhibition on the mycelial growth of both pathogenic fungi. The promising plant extracts (P. juliflora and L. camara) and antagonists (P. fluorescens and T. viride) were tested against both the pathogenic fungi under in vivo conditions along with the existing popular chemical Mancozeb. All the tested plant products and bio-fungicides showed inhibitory effect on both fungi. But the maximum survival percentage of mulberry cuttings was recorded in the treatment with T. viride (95% against F. solani and 90% against A. tenuisssima) followed by P. fluorescens (90% against both fungi) and T. harzianum (80% against F. solani and 85% against A. tenuisssima). Incase of the treatments with plant extracts and chemical fungicide the P. juliflora (60% against F. solani and 55% against A. tenuisssima) showed higher survival percentage and followed by L. camara (55% against F. solani and 50% against A. tenuisssima) and Mancozeb (55% against both fungi). In case of control only 10% of survival was recorded in F. solani inoculated cuttings and 15% survival in A. tenuissima inoculated cuttings.

The present study investigated the current child care practices of professional working mothers in Korea and their needs for substitute child care outside the home. Three hundred twenty-two professional working mothers who have children under 6 years of age in Seoul, Pusan, Taegu, and Taejon were surveyed with the use of a questionnaire. It was found that during their working hours, most of the professional working mothers put their children in the care of either the paternal or the maternal grandmothers. Others put the children in the care of a full-time housekeeper or a part-time housekeeper. While all the mothers had worked out a way to care for their children, almost all of them would use day care if facilities were available. Specifically, 42 per cent prefer child care at their work site, 21 per cent prefer family day care, and only 3 per cent indicated that they would not use any child care facilities. Most of the working mothers think that their employer should manage the day care program. Others prefer social agency or government management. Regarding costs, most prefer that costs should be split 50-50 between the employer and the family. In addition, professional working mothers wanted quality programs with educational components rather than mere custodial care. It was concluded that variety in types of quality child care programs should be available to provide working mothers the options of choosing what they want for their children. The main type of programs suggested by this study is work site based child care for children under 3 years of age. The existing law for the Saemaul Nursery School program should be implemented so as to include programs for children under 3.

Health care privatization will have a very significant impact on the quality of medical service and income redistribution and risk diversification. This study was conducted to improve the situation without too much insistence that one did not understand the essence rife about the privatization of health care. In this study, grasp the implications of the current health care debate to be privatized, and dealing with the claims accordingly. Seeks to help establish an objective perspective, looking at the pros and cons at the same time claims for medical privatization policy. The Health and diversification through the capitalist market access as part of the transition process is being overlooked as a new growth engine industries. But health care is constrained to follow the growth of universal access and how to deal with life because it is practical conduct of the person. In addition to services that are not only for the benefit of the profit or government institutions.
