吳世烈 圓光大學校大學院 1982 學位論叢 Vol.8-3 No.-

This thesis indicates that there are a study of the devices in which the images of an industry and its products can be properly implanted in the consumers' minds in this seriously complicated society at the present day, specially the history and the present condition of the logo tyoe activities in Korean industries on the assumption of the operation of CIP, the examples in forein industries, and the prospects and the problems of its operation in future. In accordance with CIP of Korean industries for the enforcement of logo type, I assume their top manager should know the following. 1. They must have a correct understanding of logo type by means of CIP. 2. In the fulfilment of logo type, the thorugh investigations should be sufficiently taken into the industries and their products before the operation. 3. If CIP system were applied and fufilled unitedly in the operation of logos type, the images of an industry and its products would be fixed in the consumerers' minds.

With rapid growth of the internet, need for the mobile communication networks is increasing. In this paper, we implement and test Mobile IP Protocol in Embedded System. Our Mobile IP-based testbed consisted of two sub-networks and each sub-network was configured to operate independently through use of router. To satisfy integrated wired/wireless network model established on the testbed design and show generality of the testbed, we implemented mobile nodes, home agent, foreign agent and router on the basis of Linux operating system. As the results of the evaluation, we confirmed that mobile nodes operated properly according to Mobile IP Protocol.

Purpose: Phytosanitary irradiation treatment can effectively control regulated pests while maintaining produce quality. The objective of this study was to establish the best irradiation treatment for mangosteen, a popular tropical fruit, using a Monte Carlo simulation. Methods: Magnetic resonance image (MRI) data were used to generate a 3-D geometry to simulate dose distributions in a mangosteen using a radiation transport code (MCNP5). Microsoft Excel with visual basic application (VBA) was used to divide the image data into seed, flesh, and rind. Radiation energies used for the simulation were 10 MeV (high-energy) and 1.35 MeV (low-energy) for the electron beam, 5 MeV for X-rays, and 1.25 MeV for gamma rays from Co-60. Results: At 5 MeV X-rays and 1.25 MeV gamma rays, all areas (seeds, flesh, and rind) were irradiated ranging from 0.3 ~ 0.7 kGy. The average doses decreased as the number of fruit increased. For a 10 MeV electron beam, the dose distribution was biased: the dose for the rind where the electrons entered was $0.45{\pm}0.03$ kGy and the other side was $0.24 {\pm}0.10$ kGy. Use of an electron kinetic energy absorber improved the dose distribution in mangosteens. For the 1.35 MeV electron beam, the dose was shown only in the rind on the irradiated side; no significant dose was found in the flesh or seeds. One rotation of the fruit while in front of the beam improved the dose distribution around the entire rind. Conclusion: These results are invaluable for determining the ideal irradiation conditions for phytosanitary irradiation treatment of tropical fruit.

Mine wastes such as acid mine drainage (AMD) can cause the detrimental effects on surrounding environment, thereby eventually threatening human health. Main objective of this study was to evaluate the neutralizing effect of fly ash (FA) as a stabilizing material AMD. Field plot was constructed in a coal waste depot which has caused aluminium-whitening adjacent to the stream. Different mixing ratios of FA were applied on a top of the soil, and then the physicochemical properties of runoff and soil were monitored. Constructed plots were as following: control (mine waste only (W)), mine waste + 20% ($w\;w^{-1}$)of FA (WC20M), mine waste + 40% ($w\;w^{-1}$)of FA (WC40M), and WC40M dressed with a fresh soil at the top (WC40MD). Result showed that initial pH of runoff in control was 5.09 while that in WC40M (7.81) was significantly increased. For a plot treated with WC40M, the concentration of Al in runoff was decreased to $0.22mg\;L^{-1}$ compared to the W as the control ($4.85mg\;L^{-1}$). Moreover, the concentration of Fe was also decreased to less than half at the WC40M compared to the control. Application of FA can be useful for neutralizing AMD and possibly minimizing adverse effect of AMD in mining area.

Bioavailability of cadmium (Cd) and arsenic (As) can be different depending on soil pH. For this reason, main purpose of this research was to compare bioavailability of Cd and As in agricultural field under varied soil pH and different extractants. Bioavailable fraction of Cd and As in soil was extracted with CaCl₂, NaNO₃, DTPA, EDTA, and low molecular weight organic acids (LMWOAs). Soil samples and cultivated crops were collected at the range of soil pH 4.5-8.5 and correlation analysis was conducted between bioavailable fraction of Cd and As in soil and total concentration of Cd and As in crops. Results showed that concentration of Cd and As in acidic soil was ranged 0.002-0.462 mg kg<SUP>-1</SUP> and 0.041-4.903 mg kg<SUP>-1</SUP> respectively. In alkaline condition, concentration of Cd and As were ranged 0.006-0.351 mg kg<SUP>-1</SUP> and 0.039-2.807 mg kg<SUP>-1</SUP> respectively. Comparing bioavailable fraction of Cd and As in acidic and alkaline soil condition, higher concentration was measured in acidic condition. Similarly, higher average concentration of Cd and Asin crops was observed in acidic condition (0.398 and 0.751 mg kg<SUP>-1</SUP> respectively) than alkaline condition (0.248 and 0.264 mg kg<SUP>-1</SUP>). Among different extractants, LMWOAs method showed higher correlation (r<SUP>2</SUP>=0.545) for Cd in acidic condition indicating that LMWOAs method could be applied for evaluating bioavailability of Cd in acidic soil. However, no high correlation was observed for As in both acidic and alkaline condition. Overall, bioavailable fraction of Cd and As can be higher in acidic condition of soil than alkaline condition resulting higher uptake of Cd and As from soil to crops. Therefore, efficient best management practice (BMPs) for Cd and As in acidic soil should be conducted for minimizing uptake of Cd and As into crops.

Use of an electron kinetic energy absorber improved the dose distribution in mangosteens. For the 1.35 MeV electron beam, the dose was shown only in the rind on the irradiated side; no significant dose was found in the flesh or seeds.
