Objectives: This study examined search on how the obesity indices, that are largely used in clinics such as waist circumference(WC), body mass index(BMI) and waist-hip ratio(WHR), are related to the visceral fat that was measured from abdominal computed tomography(CT) and the ratio of visceral fat/subcutaneous fat. Then, two groups were compared in order to find out which characteristics of ordinary adults relationship with the abdominal obesity. Two groups are divided as follows; ones who are obese based on the measurement of WC and the others who are obese based on the level of BMI. Methods :A group of 63 test subjects that were gathered in the oriental medical hospital of Kyung-Won university is divided into two groups; ones (n=51, general obesity; group A) who have BMI≥25 and WC≥85, and the others (n=12, abdominal obesity; group B) who have BMI<25 and WC≥85. Then, each group’s obesity indices, abdominal CT, lipid level, glucose, adiponectin, leptin and C-reactive protein(CRP) are compared. In addition, subjects are again divided into two to examine the characteristics; ones (n=14, visceral obesity; group C) with visceral obesity based on the ratio between visceral fat and subcutaneous fat measured through abdominal CT, and the others (n=38, non-visceral obesity; group D) who are obese but not viscerally obese. Results & Conclusions :As a measurement that applies abdominal visceral fat and subcutaneous fat, BMI and WC can be considered as an appropriate obesity index while WHR cannot appropriately apply the abdominal fat amount. Moreover, the study indicates that abdominal obesity group based on the ratio of visceral fat/subcutaneous fat has more significant difference than the abdominal obesity group based on the WC in case of blood lipid index.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

This study was performed to measure the skin absorbed doses from full mouth standard intraoral radiography(14 exposures) in bisecting angle and paralleling techniques. Thermoluminescent dosimeters were used in a phantom. Circular tube collimator(60mm in diameter, 20cm in length) and rectangular collimator(35mmX44mm, 40cm in length) were set for bisecting angle and paralleling techniques respectively. All measurement sites were classified into 8 groups according to distance from each point of central rays. The results were as follows: 1. The skin absorbed doses from the paralleling technique were significantly decreased than those from the bisecting technique in both points at central ray and points away from central ray. The percentage rates of decrease were greater at points away from central ray than those at central ray. 2. The skin absorbed doses at the lens of eye, parotid gland, submandibular gland and thyroid region were significantly decreased in paralleling techniuqe, but those of the midline of palate remained similar in both techniques. 3. The highest doses were measured at the site 20mm above the point of central ray for the mandibular premolars in bisecting angle technique and at the point of central ray for the mandibular premolars in paralleling techniques. The lowest doses were measured at the thyroid region in both techniques.

Fineness Modulus is a term used as an index to the fineness of sand. It is well - known that the modulus distribution of sand plays an important role in achieving the desired properties of mortar. The maximum size of sand is also important parameter in mortar. These parameters affect workability, strength and unitweight of mortar. In tills study, different sand gradings were used to investigate effects of fineness moduli of sand for examination about the workability, strength and unit weight characteristics of cement mortar. Two kinds of sands with various size distribution and three kinds of fine aggregates with the similar particle size distribution (Sieve No.16~30, No.30~50, No.50~100) were used. Water-cement ratio (W/C) of mortar mix was kept constant for all the trial mixes with sand of different fineness modulus. Major findings of tills study are: (a) Fine sand with the similar size distribution reduces the workability and unit weight of cement mortar. (b) The compressive strength of mortar is not sensitive to sand grading variations. (c) The compressive strengths at the age of 28 days range from 32.1 to 54.1 MPa. (d) The sand with standard modulus distribution has better positive effects on the properties of the mortar.

본 연구에서는 시설하우스 폐양액이 고추의 생육과 양분 흡수에 미치는 영향을 평가하고 폐양액 관주시 부가적으로 얻을 수 있는 관개 효과를 산출함으로써 폐양액의 토양 시비에 따른 농업적 가치를 평가하였다. 시설하우스 폐양액의 토양 곽주시 Ca, Mg, K 등 염류의 증가로 인하여 pH와 EC는 상승하였고, 총질소는 암모늄태 질소와 질산태 질소의 증가와 함께 처리 후 100 mg kg^(-1) 이상 증가하였다. 고추 생육은 화학 비료 70% 및 폐양액 30% 혼합처리구와 화학비료 50% 및 폐양액 50% 혼합치리구에서 양호하였으며 양분 흡수도 동일한 경향을 나타내었다. 고추 수확량은 화학비료 70%, 및 폐양액 30% 혼합처리구에서 가장 높은 것으로 조사되었다. 1일 발생되는 폐양액(288 L 10 a^(-1)day^(-1))을 토양에 시용하여 증발산되는 수분을 보충할 경우 최고 409.86 m²의 면적을 관개할 수 있는 것으로 산출되었다. 이상의 결과를 통해 폐양액의 토양 처리는 화학비료 대체 효과와 폐양액의 정화 효과를 동시에 얻을 수 있으며 적정량 사용시 주변 환경에 미치는 영향을 최소화하면서 지속적인 처리가 가능할 것으로 판단되었다. Waste of the hydroponic solution from the plastic film house cultivation was recycled to grow the red pepper(Capsicum annum L.) in upland fields as supplement for plant nutrients and irrigation sources. Application of hydroponic waste solution increased the pH and EC of the soils, coupled with the increases in the concentrations of exchangeable cations(Ca, Mg, and K), total nitrogen, NH₄-N, and NO₃-N. Growth and yield of red pepper were highest when the treatment of chemical fertilizer(70%) was combined with hydroponic waste solution(30%). Amounts of the daily producing hydroponic waste solution were 2,880 L ha^(-1) day^(-1) from the experimental facilities and this could irrigate 409.86 m?of area to compensate for the amount of water loss by evapotranspiration(3%). The overall results demonstrated that hydroponic waste solution could be recycled as plant nutrients and irrigation water resources for enhancing soil fertility and environmental quality.

This study was carried out to examine the characteristics of root system for seedlings of Hibiscus syriacus L. on the different soil conditions as a basic study for the stock of top-root cultivars. The obtained results are summarized as follows; It was significantly different on soil hardness between upland soil with 13 kg f/cm2 until 60 cm depth and waste landfill soil with 5 kg f/cm2 until 5 cm depth. But it was not measured soil hardness under 30 cm of waste landfill soil because of waste base. But soil pH was not different between soil conditions. The root depth of 'SKK 91-3' growing on upland soil was 81.0 cm and it was significantly different as compared with that of 'SKK 91-3' on the waste landfill. In addition, 'SKK 91-3' growing on upland soil had more root weight, root width, root number, main root diameter, and shoot growth than that on the waste landfill. Therefore it was suggested that soil condition affect root growth of seedlings in Hibiscus syriacus L. and then induce top-root system.
