To analogize the result of the test through explaining the correlation of bone mineral density (BMD) test value between proximal femur and lumbar spine at age. It is based on 62 cases who visited the out-patient department. They were classified into three groups by age, group I (30~40 yr) and II (40~60 yr) and III (60~80 yr). Then we evaluated the average and the degree of correlation between the three groups and analyzed the correlation of the three sites according to the BMD result and T & Z-score through the t-test analysis. The results are listed below, first, if rise in age T-score is lower and over 60age occurred osteopenia, second, compared three groups, the correlation of BMD results was some of the highest between Lumbar spine and Proximal femur of T-score & Z-score. the correlation of BMD results is very high. It is regarded that there will be a clinical availability which can analogize the result of a part by using the result of the other part.

The interest in male osteoporosis is increasing as the incidence of osteoporotic fractures has increased not only in female but also in male due to the increase of old age population thanks to the development of medical science and science in general. Therefore, this study is to find factors related to bone mineral density of male older than 40 years old, to investigate the incidence of the male osteoporosis and to provide a basic result for prevention and medical treatment for the male osteoporosis. The incidence of the osteopenia and the osteoporosis at L-spine was 45% and 12.9% respectively and the incidence of them at femur was 51.9% and 7.63% respectively, among male older than 40 years old who took a medical examination. It was higher than the existing study results conducted to male older than 50 years old in USA and Europe. The incidence of them at both of L-spine and femur showed a significant difference depending the age groups. As the age increases, the average bone mineral density decreases at both of L-spine and femur. And as the weight increases and the body mass index is higher, the incidence of the osteoporosis decreases. There was no significant relation with the incidence of the osteoporosis depending on the exercise, the smoking and the drinking, but the number of exercise, smoking and drinking changes the quantity of bone and are factors influencing the bone mineral density of male person.

This paper measures the impacts of the Korea-China Free Trade Agreement (FTA) on the emissions of carbon dioxide ($CO_2$) in Korean export industries. The Korean industrial exports were forecasted by employing Bayesian Kalman Filter Vector Auto-Regression (BVAR) model. The emissions of $CO_2$ were then estimated by applying the $CO_2$ emission coeffcients on the conditionally forecasted values of export by industries. Under the conditional scenario of the 50% reduction in current tariff rate through FTA between Korea and China, the total $CO_2$ emissions in Korea were expected to increase by 1.96% compared to the BAU (Non FT A) trend at the end of 2010. Another conditional scenario with no tariff after 2012 was also adopted. In this case, the total $CO_2$ emlssions were estimated to increase by 2.06% compared to the BAU up until the end of 2014. These facts imply that the FTA between Korea and China would not result in the significant increase of $CO_2$ emissions in Korea.

Considering that few studies had paid attention to the living characteristics and social environment surrounding amblyopes, the present study surveyed the parents of children aged 3 to 12 and diagnosed-with amblyopia to analyse the time when the children were first diagnosed-with amblyopia, the characteristics of their living environment and the socio-environmental factorsand to delve into correlations. For the purpose of this study, 104 parents of patients in 4 hospitals in Seoul, Gyeonggi and Incheon consented to participate in the survey from September 2 to November 23: 2013. As for the time when the children were first diagnosed with amblyopia: the age of 4 accounted for the highest percentage(28.8%). The older the parents were: the later the children were diagnosed with amblyopia (p<.01). The higher the education of parents, the earlier the diagnosis of amblyopia(p<.05). The present findings-will be conducive to decreasing the number of patients who have no choice but to live-with low vision for life by missing some timely visual acuity tests and ophthalmological examination and particularly to developing a social safety net that can realize national medical welfare for the low-income families and the socially disadvantaged class.With the help of information technology.

This experiment was carried out at National Crop Experiment Station in 1994 to obtain basic information of growth characters and yield of rice under various seeding methods in direct seeding on dry paddy. Hwaseongbyeo sown on April 27 by flat drill seeding, high ridged drill seeding and hill seeding under different seed conditions, soil convering after seeding and irrigation methods. Nitrogen applied 150kg /ha by 3 times split application at rate of 40:30:30％ (basal: 5th leaf stage:panicle initiation stage). Seedling stands were higher in flushed irrigation water after seeding than in irrigation at 3rd leaf stage, and it also was higher in high ridged drill seedings than in flat drill seedings. Days for seedling stand, heading date were shorten 6~10 days, 2~3 days by flushed irrigation water after seeding, respectively. Number of tiller was more in high ridged drill seedings than conventional seedling method(Flat drill seeding ＋ intact seed ＋ soil covering after seeding ＋ irrigation at 3rd leaf stage after seedling stand) at early growth stage, but the most tiller number was highest in developed seeding method(Flat drill seeding ＋ soaked seed ＋ non soil covering after seeding ＋ fulshed irrigation water after seeding) at heading stage among used seeding methods. Lodging index was slightly high in high ridged drill seeding and conventional seeding. Field lodging was degree 1 in high ridged drill seedings and developed seeding, Milled rice yield in developed seeding was increased 7％ compaired with conventional seeding(5.35t /ha).
