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.

There has been a lot of growth more than 10% in the information security industry. In accordance with the industrial growth, it increased needs for the information security manpower development as a national problem. But there is an imbalance between demand and supply of the information security manpower in terms of the quantity and quality. It is mainly caused by the curriculum of the information security is made considering for suppliers not for demanders. As a resolution to solve this problem, we suggest the curriculum of information security for vocational education and training. As the information security area is wide in view of required knowledge and technology, we design the curriculum by selecting major occupation type from the information security manpower distribution and products and then by investigating the job description using NCS(National Competency Standard). And we compared the curriculum to that of two or three year diploma courses in Korea.

Reviewing the meaning aid task of balance of regional development, this papa examines the causes of the underdevelopment of rural areas in relation to the urbanization process, probes the concept, principle and necessity of rural community development, and suggests the policy tasks for rural community development in the perspective of regionally balanced development. Since 1960's, Korea has pursued a growth-oriented economic policy. The focus on the aggregated growth, however, has resulted bo invite some regional disparity problems. In the process of development, regional disparity problems were quite a large rural areas compared with urban areas relatively. The under-development of rural areas is deeply correlated with the overcrowding (or overconcentration) phenomena of urban(or metropolitan) areas. The urban-biased policy is the primary cause of the deepening regional imbalance structure between urban and rural areas. The inter-regions equitable and well-balanced development is one of the national policy issues by which the government is confronted, since the issue is closely related with national quality of life. Main three policy tasks for rural community development were 'the new paradigm of development policy' , 'local-oriented policy' and 'human-oriented policy'.

본 연구는 수도권을 대상으로 종사자수와 취업자수를 지표로 직장과 주거지의 일치현상을 고찰하고 직주비와 통근통행간의 관계를 탐색한 것이다. 수도권에서는 2005~2010년 사이에 도시의 중심지기능을 수행해 온 도심지역에서 종사자수가 감소하고 인구증가 현상이 둔화되었고, 경기도가 차지하는 비중이 증가하면서 고용과 인구의 교외화현상이 진행되었다. 수도권에서는 종사자수에 비해 취업자수의 증가현상이 두드러지면서 취업자수 초과현상이 심화되었고, 이는 직주비를 감소시키는 요인으로 작용하였다. 특히 경기도에서의 직주불균형이 심화되었다. 사무직, 판매직, 전문직 등에서는 직주불균형이 개선된 지역이 많았지만, 단순노무직과 서비스직에서는 직주불균형이 심화된 지역이 많았다. 직종별로는 업무중심지일수록 더 많은 수의 직종에서 직주불균형이 개선되었다. 직주비가 높은 지역일수록 통근통행의 자족도가 낮게 형성되었으며, 다른 지역에서 유입되는 역외유입통행이 차지하는 비중이 높았다. 종사자수가 취업자수에 비해 월등하게 많았던 주요 고용중심지에서는 직주비와 역외유입통행률이 모두 감소하는 경향을 보였다.

In this study, the characteristics of tree growth and soil environment were analyzed at 5 sites that had been planted on the back slope of dam for more than 15 years in Korea. First, as a result of investigating the growth of 15 trees planted on the back slope of the dam, the average height was 10.6m, diameter at roots was 27.3cm, and DBH was 22.9cm, showing good growth status of most of the trees. In particular, the growth levels of pine, hackberry, and oak were similar or better than those of general forests and artificial ground. As a result of excavating and investigating the roots of trees, horizontal roots grew well in the left and right directions of the back slope of the dam, and the growth of vertical roots was insufficient. Currently, the roots of trees do not directly affect dam safety, but they may continue to grow in the long term and interfere with dam management. Second, the physicochemical characteristics of the soil on the back slope of dam were generally above the intermediate level in terms of landscape design standards, and were similar to those of the domestic forest soil. Therefore, although it was judged to be suitable for plant growth, isolation of the site, soil acidification, and nutrient imbalance may affect tree growth and forest health in the long term. Through this study, it was possible to confirm the potential and applicability of planting area on the back slope of dam as an ecological base. Continuous monitoring is required for safety management and ecological value of dams in the future, and through this, it will be possible to secure the feasibility of planting trees on the slopes of new or existing dams and improving management.

Background: Although the modified Blalock-Taussig shunt remains the mainstay method of palliation for augmenting pulmonary blood flow in various congenital heart diseases, the shunt must be carefully designed to achieve the best outcomes. This study investigated the effect of shunt configuration on pulmonary artery growth and growth discrepancy. Methods: Twenty patients with successful modified Blalock-Taussig shunt takedown were analyzed. Pulmonary artery and shunt characteristics were obtained using computed tomography scans. Differences in the baseline and follow-up diameter ratios and growth in the ipsilateral and contralateral arteries were calculated. The angle between the shunt and pulmonary artery, as well as the distance from the main pulmonary artery bifurcation, were measured. Correlations between pulmonary arteries and shunt configurations were analyzed. Results: The median interval time between shunt placement and takedown was 154.5 days (interquartile range, 113.25-276.25 days). Follow-up values of the ipsilateral-to-contralateral pulmonary artery diameter ratio showed no significant correlation with the shunt angle (ρ=0.429, p=0.126) or distance (ρ=0.110, p=0.645). The shunt angle and distance from the main pulmonary bifurcation showed no significant correlation (ρ=-0.373, p=0.189). Pulmonary artery growth was negatively correlated with shunt angle (ipsilateral, ρ=-0.565 and p=0.035; contralateral, ρ=-0.578 and p=0.030), but not with distance (ipsilateral, ρ=-0.065 and p=0.786; contralateral, ρ=-0.130 and p=0.586). Conclusion: Shunt configuration had no significant effect on growth imbalance. The angle and distance of the shunt showed no significant correlation with each other. A more vertical shunt was associated with significant pulmonary artery growth. We suggest a more vertical graft design for improved pulmonary artery growth.

It is well known that dietary protein affects the growth performance and carcass composition of poultry. Over the last several decades, numerous studies have been carried out to investigate to optimize the level of dietary protein since the protein is an important and expensive constituent in poultry feed. It is generally accepted that dietary protein should represent a balance of amino acids supporting the requirements for growth and maintenance of birds. A protein with balanced essential amino acids that matches a bird's requirement and sufficient non-essential amino acid nitrogen to enable the synthesis of all of the non-essential amino acids, is referred to as an 'ideal protein'. Feeding of excess protein or amino acids may result in an amount of nitrogen emission. Most common method to reduce nitrogen emission is using diet formulation which has lower dietary crude protein level and higher concentration of amino acid supplements. However, there are conflicting reports whether low protein diets supplemented with synthetic amino acids can obtain the growth performance equal to high protein diets. Excessive nitrogen excretion caused by amino acid imbalance also may influence the environment of poultry house due to ammonia production from uric acid. These environmental conditions may increase the incidence of skin problem or respiratory diseases of chickens. Various strategies based on comprehensive understanding should be tested to optimize nitrogen utilization and reduce nitrogen emission while maintaining the performance in poultry production.

A number of fallow paddies field continues to increase because of adverse agricultural circumstance such as upsurge income of foreign products, increase of labor costs in local community, imbalance between productivity and profitability etc. Such fallow paddies are necessary to be protected against weeds and trees. If fallow paddies are not managed, it will be devastated and needed cost for re-cultivation. Therefore, management of gradually increased fallow paddy fields should be conducted. In this study, the effect of plants growth inhibition and water quality purification through the control of flood in fallow paddy were examined in an experimental field. The managed and unmanaged fallow paddies through the control of water depth were constructed in the experimental field. The monitoring was conducted from 2005 to 2007. As the result, the managed fallow paddies were more effective than the unmanaged ones on the growth inhibition and water purification. In addition, when the fallow paddy is managed with regular water depth, it was the most effective in the plants growth inhibition.

GH-transgenic coho salmon (Oncorhynchus kitsutch) juveniles in tGH＊T$_3$and tGH*PTU were fed with the diets containing 1 ug/g fish of 3,5,3'-triiodo-L-thyronine (T$_3$) and 30 ug/g fish of 6-n-propyl-2- thiouracil (PTU), respectively, to assess the effect of these drugs on the change of physiological activity, growth and survival rate in comparison with normal transgenic (tGH＊C) and nontransgenic coho salmon (Wild) for 90 days. Although the daily food intakes of all transgenic (tGH)-groups were higher than Wild, the amount was reduced by exogenous PTU supply. The fred efficiencies of tGH-groups were lower than Wild, but the efficiency was reduced both by T$_3$and PTU. The survival rate of tGH-group was significantly higher than that of Wild, but there was no significant difference among tGH-groups. Although the growth of tGH-coho salmon was faster than Wild. the growth rate of transgenic salmon was increased by exogenous T$_3$, but was reduced by PTU Plasma TT$_4$levels of tGH-groups was approximately 2-fold higher relative to Wild, but there were no difference of plasma TT$_4$levels among tGH-groups. plasma TT$_3$level or tGH-coho salmon was increased by exogenous T$_3$administration, but was reduced by exogenous PTU. In addition, although plasma GH levels of all tGH-groups were higher than that of Wild, the GH level in plasma of transgenic coho salmon was increased by exogenous T$_3$and reduced by exogenous PTU. In the meantime, the transgenic fishes also displayed head, jaw and opercular abnormalities typical of the offsets of this gene construct in coho salmon, indicating that some imbalance in growth processes has been induced. However, the abnormalities of transgenic coho salmon was reduced following exogenous PTU administration.
