  • The effects of the simulated acid rain on the growth response and water status of Glycine soja was observed in 2 months-old seedlings. The seedlings were treated with acid rain(pH 3.5), three times per week. Glycine soja showed significant reduction in the total length, total weight, dry weight, water contents and top/root ratio after treatment of simulated acid rain(pH 3.5) for 56 days. The growth of shoot was more susceptible to acid rain than that of roots. On the contray, Number of lateral roots, water saturation deficit and epidermis transpiration was higher than that of control(pH 5.6) after 56 days treatment of simulated acid rain.

  • This study was conducted to suggest a management plan for legally protected trees in Gwangju, Gyeonggi-do by examining their distribution and growth. A literature review and field survey of these trees were conducted to derive problems and usage plans, with a number of key results. Among the legally protected trees (77 species in total) in 74 locations within Gwangju, Gyeonggi-do, the growth status of 74 species (96.10%) was above average, indicating that most legally protected trees were growing without any issues. Despite the results, analysis of the function of these legally protected trees indicated that there was low diversity and utilization of these trees as only trees in 33.77% were used as resting places or pavilions while those in 66.23% were used for landscaping or other purposes. It was assumed that these legally protected trees and the areas surrounding them in Gwangju, Gyeonggi-do will be used as community spaces if the environment is improved. This includes converting these areas into small parks or resting places for residents. In addition, further research should be carried out to maintain good growth conditions for these legally protected trees in general and to explore various plans that allow utilization of the surrounding natural ecosystem, human environment, and cultural elements in order to enhance the quality of the region and improve it as a living space for residents.

  • To clarify the effects of acid precipitates on histological damage, water status, and growth of Pinus densiflora green house experiment applyin simulated acid rain was carried out. Contact angle of water droplet on needles of P. densiflora seedlings treated with simulated acid rain of different pHs simulated acid rain was, the more rapid transpiration was. Leaf water potential after water withdrawal was also reduced rapidly in proportion to acidity of simulated acid rain. Height growth of P. densiflora seedlings treated with simulated acid rain of pH 2 decreased, while growth of seedlings treated with that of pH 3 and 4 increased comparing with that treated with normal rain of pH 5.6. pH of cultivated soil in pH 2 plot was acidified with the amount of simulated acid rain applied but that in pH 3 and 4 plots did not show any directional change. From those results, it could be interpreted that decrease of height growth in pH 2 plot was originated from multiple effects of water deficit from rapid transpiration and soil acidification. On the other hand, increased of height growth in pH 3 and 4 plots would be originated from the supply of N and S included in simulated acid rain.

  • The influence of nutrition during early life on physical growth as well as mental development has been thoroughly discussed in the literature. The physical dimensions of the body are greatly influenced by nutrition, particularly during the period of rapid growth in early childhood. Nutritional status affects every pediatric patient's response toillness. Good nutrition is important for achieving normal growth and development. It is indicated that permanent impairment of the central nervous system may result from dietary restriction of imbalance during certain periods of life. If children under 3 years of age show a good nutritional status, it may be assumed that they are well nourished. Several common diseases of children such as iron deficiency, chronic constipation and atopic dermatitis are known food related diseases. Patients with chronic illness and those at risk of malnutrition should have detailed nutritional assessments done. Components of a complete nutritional assessment include a medical history, nutritional history including dietary intake, physical examination, anthropometrics (weight, length or stature, head circumference, midarm circumference, and triceps skinfold thickness), pubertal staging, skeletal maturity staging, and biochemical tests of nutritional status. The use of age, gender, and disease-specific growth charts is essential in assessing nutritional status and monitoring nutrition interventions. Nutrition assessment and dietary counseling is helpful for the cure of disease, and moreover, the prevention of illness.

  • This study was designed to examine the relationships between empowerment and child care teachers' intention of teaching, the reason for teaching intent. The subjects were 181 child care teachers from Chungcheongnamdo and the city of Daejeon, Korea. This study was conducted using questionnaires. The results were as follows: first, there were significant relationships between empowerment and child care teachers' intention of teaching and, the reason for teaching intent. There were positive relationships between decision making, professional growth, status, self-efficacy, autonomy, impact empowerment and child care teacher' intention of teaching and, the reason for teaching intent. Second, child care teachers' intention of teaching and the reason for teaching intent were affected by empowerment. Status and professional growth empowerment were the most predictive variables for the child care teachers' intention of teaching. The impact and self-efficacy empowerment were the most predictive variables for enjoy working with children, impact and professional growth empowerment were the most predictive variables for finding meaning in teaching, impact and status empowerment were the most predictive variables for opportunities to face ongoing challenges, and achievement motive. Status empowerment were the most predictive variable for reasonable pay and working environment, stability and skill. Therefore, status and impact empowerment were the most predictive variable for the reason for teaching intent.

  • The growth of a game character is represented by the addition and subtraction of the status value. The status factors are variously defined and used depending on the kind of games. In this paper, we propose how character 's status elements are defined and used. We also propose a method for assigning a status value when generating a character considering growth. This method is designed using genetic algorithms to link the growth of a character with an element of time and to generate a character with the appropriate status value according to the change of time. The proposed method is verified through experiments based on time variation.

  • Objectives: This study aimed to estimate the trajectory of depressive symptoms among aged 20 years adults and examine the direct and indirect pathway linking socioeconomic status(education attainment, household income, occupation), alcohol use and depressive symptoms. It particularly focused on whether alcohol use would mediate the relationship between socioeconomic status and depressive symptoms. Methods: This study analysed 13,763 households of Korean Welfare Panel Study 1st, 2nd, 3rd data using Latent Growth Curve Modeling. Results: The results showed that study participants tend to decrease depressive symptoms with years. Similar to the findings of the previous studies, education attainment and household income among the socioeconomic status factors effected directly depressive symptoms and indirectly by mediating alcohol volume controlling sex and age. Conclusions: Based on findings of this study, the policy and practical implications were discussed.

  • The relationship between socio-economic status and food and nutrient consumption patterns was studied in 7,370 Koreans aged 20 years and older in the 1995 Korean Health and Nutrition Survey. The aim of this study was to investigate the effect of rapid economic growth on food and nutrient consumption for Korean adults in the last 30 years. Monthly household income, and individual's educational level and occupation were chosen as variables of socio-economic status for individuals. A one day 24 hour recall method was used for the dietary survey. One way analysis of varience was adopted to test tole association between socio-economic variables and food and nutrient consumption patterns. Individuals who had a high socio-economic status had significantly higher daily intake of most of the nutrients including calcium, vitamin A, vitamin B$_2$which reached above the recommended dietary allowances(RDA) and a higher percentage energy consumption from fat. In addition, individual who belonged to a low socio-economic status consumed less animal foods, including meat, egg, milk and consumed low proportion of energy from fat. The results suggest that in spite of rapid economic growth during the last 30 years in Korea, individuals who belonged to low sorio-economic status categories are still nutritionally vulnerable. Among the sorio-economic variables, income and education except occupation were the influential factors on the food and nutrient consumption of Koreans. Therefore, nutrition policy should focus on influencing the dietary patterns of lower social class individuals to improve the health status of the population as a whole.
