The objective of this study was to evaluate the quality-based characteristics of Prunus mume fruit syrup, which is manufactured with various sugared sweeteners for suggestion of suitable alternative sweetener. Sweetener such as sucrose (MHP1), crystalline fructose (MHP2) and liquid fructo-oligosaccharide (MHP3) are used to manufacture Prunus mume fruit syrup. The sugar content of MHP1, MHP2 and MHP3 showed 53, 54 and $36^{\circ}Brix$, respectively. The total organic acid content of MHP1, MHP2 and MHP3 was 2.22, 3.07 and 3.71%. The total free sugar content of MHP1, MHP2 and MHP3 was 54.39, 47.52% and 31.62%, respectively. The appearance of MHP1 and MHP2 remained unchanged for the entire period but MHP3 had molded since the first week. This was as a result of the low total free sugar content in MHP3 sugared with liquid fructo-oligosaccharide compared to MHP1 and MHP2 sugared with solid sucrose and fructose. The sensory characteristics of MHP2 manufactured with crystalline fructose indicated an above average quality, indicating that it is difficult to manufacture Prunus mume fruit syrup using liquid sugar. It is suggested that crystalline fructose characterized solid form and lower glycemic index than sucrose be useful to manufacture Prunus mume fruit syrup as alternative sweetener.

Recently, some policies for reducing standby power, which has quite an effect on electricity consumption, have been employed all over the world. This study surveys the present condition of standby power for major electric home appliances during three years and analyzes the result of technical development reducing standby power. It presents how the industry paid attention to applying the technique of reducing standby power to electric appliances and how it affects the product's energy efficiency. We survey the standby power's change for six items, which were selected from the major electric appliances available on the market. It analyzes the difference of standby power consumption between appliances with a standby power reducing technique and those without during the latest three years. The amount of the average standby power is also compared. The comparison data confirms that the industry's effort and application of reducing standby power contribution has contributed to increasing an appliance's energy efficiency. This study restricted the analyzed items to six appliances, which has been a low volunteered involvement in the standby power reducing program. It is important for reducing standby power consumption of appliances because it contributes to saving electric energy at home and abroad. The development of the standby power reducing technique is needed for more appliances. Along with the development of the standby power reducing technique in the industrial field, it also necessary for consumers to enlarge their understanding of standby power reduction for economic, social, and environmental values.

Compression stress block used to concrete structure design substitutes equivalent triangle, rectangle, trapezoid and parabola-rectangle stress block for actual concrete stress distribution. Its shape is different in design code of the major advanced countries. It reflects the material feature of each of country. Presently, compression stress block of korea concrete design code is equal to it of ACI code that doesn't reflect the material feature of the high strength concrete. So, many research conclusions showed that it is not reasonable. The study compares concrete stress blocks of the major advanced countries and does an experiment on concrete compression stress block to know the material feature of the concrete in korea. It obtains the operating load and the concrete strain in experiment and draw stress block parameters. It compares stress block parameters applied to design code with those by the experiment conclusion. In addition, It compares and analyses nominal axial force-moment diagram by the stress block of the major advanced countries.

In this study, the initial in vivo pharmacokinetic changes according to the routes of drug administration were investigated using bioimaging techniques. The purpose of this study was to quantify the degree of distribution of each major organ in normal mice over time by acquiring Positron Emission Tomography/Computed Tomography images while administering routes F-18 fluorodeoxyglucose such as intravenous, intraperitoneal and per oral, a representative diagnostic radiopharmaceutical. Dynamic Positron Emission Tomography images were acquired for 90 minutes after drug administration. Radioactivity uptake was calculated for major organs using the PMOD program. In the case of intravenous administration, it was confirmed that it spread quickly and evenly to major organs. Compared to intravenous administration, intraperitoneal administration was about three times more absorbed and distributed in the liver and intestine, and it was showed that the amount excreted through the bladder was more than twice. In the case of oral administration, most stayed in the stomach, and it was showed that it spread slowly throughout the body. In comparison with intravenous administration, it was presented that the distribution of kidneys was more than 9 times and the distribution of bladder was 66% lower. Since there is a difference in the initial in vivo distribution and excretion of each administration method, we confirmed that the determination of the administration route is important for in vivo imaging evaluation of new drug candidates.

The feasibility of graphoepitaxial growth of compound semiconductor has been studied. Two kinds of substrates were prepared; one is smooth substrate, the other one is a periodic structured substrate. ZnO film was deposited on both substrates by sputtering, and thermal treatment was performed to improve the crystal quality and investigate the effect of the periodic structure. Atomic force microscopy (AFM) and photoluminescence (PL) were used to characterize the samples. As a result, very similarchange, the improvement of crystallinity, has been observed from both samples, except the sample annealed at the highest temperature. It implies the periodic structure affects the crystallinity of the films, and the graphoepitaxy of compound semiconductors is possible by using appropriate surface structure.

This paper deals with nonparametric estimation of discontinuous regression curve. Quite number of researches about this topic have been done. These researches are classified into two categories, the indirect approach and direct approach. The major goal of the indirect approach is to obtain good estimates of jump locations, whereas the major goal of the direct approach is to obtain overall good estimate of the regression curve. Thus it seems that two approaches are quite different in nature, so people say that the comparison of two approaches does not make much sense. Therefore, a thorough comparison of them is lacking. However, even though the main issue of the indirect approach is the estimation of jump locations, it is too obvious that we have an estimate of regression curve as the subsidiary result. The point is whether the subsidiary result of the indirect approach is as good as the main result of the direct approach. The performance of two approaches is compared through a simulation study and it turns out that the indirect approach is a very competitive tool for estimating discontinuous regression curve itself.

We have investigated the electro-optical characteristics of image sticking in AC PDP. Although Image sticking is one of major factors to determine display quality in AC PDP, so far, it has not being reported why it is occurred and how we can prevent it. In this experiment, we have analyzed the effect of MgO protective layer and phosphor on the image sticking and we have measured the difference of firing voltage, brightness and discharge current between sticking image and normal image in AC PDP. As a result, Phosphor degradation is a more major factor than MgO protective layer and the firing voltage of gas discharge in sticking image is higher than that of normal discharge.
