일반적으로 수심측량은 해저면의 수심을 측량하는 방법이다. 해도상에 표시되는 모든 수심은 200Khz 주파수를 사용하는 에코사운더를 사용하여 측정된다. 이 연구에서는 부니층의 두께조사를 위해 이중 주파수인 33Khz와 200Khz를 사용하였다. 준설구역상에 부니층의 물량을 조사하는 방법을 알게 되며 부니층의 유무에 대한 검증을 위해 RI 테스트가 측량 후에 수행된다.

Experimental investigation of the interaction between dual spray formed by swirl type injector was conducted. Experimental parameter was fuel temperature, varied in the range from $-20^{\circ}C$ to $120^{\circ}C$. Measuring parameter were vertical distance from injector tip to patternator and gap between injectors. Volumetric distiribution and SMD were measured for the various combination of parameters. The results of present study show that the arithmetic sum of each of spray is not equal to dual spray, but it is equal above specific fuel temperature. As the increases of fuel temperature, SMD decreases and becomes more uniform. As the increases of gap between injectors, fuel volume and SMD at collision area increases, but penetrated fuel decreases.

We have been measuring the voltage differences by using submarine cables in the Tsushima and in the Tokara Straits. The aim of these measurements is to estimate the volume transports of the ocean currents through those straits. In this paper, the voltage differences are compared with the corresponding sea level and air pressure differences between straits. Especially in the Tsushima Strait, the voltage difference is consistent with the air pressure difference as well as the sea level difference.

Silicon nanowires (SiNWs) were fabricated by a metal-assisted chemical etching of Si and the porous structure on their surfaces was controlled by changing the volume ratio of the etching solution composed of hydrofluoric acid, hydrogen peroxide, and deionized water. The concentration of hydrogen peroxide as the oxidant was varied for controlling the porosity of SiNWs. The optical properties of porous SiNWs were unique and very different from those of single-crystalline Si, as characterized by measuring their photoluminescence and Raman spectra for different porosities.

The antiinflammatory and analgesic activities of higenamine were evaluated by measuring edema volume and pain threshold in adjuvant arthritic rats and acetic acid-induced writhing test in mice. Higenamine, with consecutive oral administrations at doses of 10 and 50 mg/kg/day, showed significant antiedemic effect and elevation of pain threshold during the secondary lesion of adjuvant arthritis. Higenamine also showed a significant inhibition of acetic acid-induced writhing syndrome with a single oral administration (200 mg/kg). From these results, it is postulated that higenamine might possess both of centrally and peripherally mediated analgesic properties.

This paper presents results from field studies carried out to monitor off-target droplet movement of endosulfan insecticide applied to the Korea chestnut tree area. As a results, mean airborne drift values were recorded 25m as average from downwind of a single flight line(sample line) in mountain terrain and mean effective swath width was recorded 19.5m as average in a plain. In terms of characteristics of geography of Korea aerial application is mainly carried out in mountain terrain. The equipment, weather conditions, and appropriate aerial spray technic are required for effective aerial application. In particular, the pilot can get effective results when he only sprays with consideration of environment factors since there is much turbulence in mountain terrain. Eventually, the most effective factor of droplets drift is to estimate the local weather conditions exactly.

In order to study the extraction mechanism of barley tea, some factors affecting extraction and physical properties of roasted barley and extract were examined. The main results of this study are as follows : 1. The roasted barley particles used as the raw materials were amorphous. Under the extraction condition used the average swelling ratio of the particles and imbibed volume were 1. 3g and 1.65ml/g respectively. The maximum soluble solid content in the roasted barley was 67.07%. 2. The concentrations of the barley extracts were determined by measuring their optical densitis at 420nm and the relationship between the concentration(C) and optical density(O. D.) was expressed as : C=6, 178XO. D. As shown in the following relationship, the viscosities(u: Ns/m2) of barley extracts were Influenced by concentration(C : kg/m3) and temperature(T : C). $\mu$=5.6731$\times$$10^{-4}e^{2.7}^{\times10^{{-3}\times{C}}$$\mu$=3.577$\times$$10^{-3}e^{{-3.02}\times{10^{-2}\times{T}}$

A weight-rate disposal system for food waste has been implemented in all over the country. The food waste disposal system is a system paying service charge according to the volume of food waste, which means the more we produce waste, the more we have to pay as much.Since this policy was introduced, each of apartment, villa, etc and other buildings must install the food waste disposal system. We can say that there are strong points in this paper for us to install a weight monitor on the channel of the floor each, accumulate the fares automatically and collect the fares at the end of every month.

An experimental study was conducted on the optimal configuration and size of ADFL(Aerodynamic Focusing Lens) which used in modified ISPM(In-Situ Particle Monitoring). The particle counting efficiency has been known as a function of distance and size of ADFL, thus we varied these parameters to find out the optimum values. From a result of experiment, it was found that two lenses and 6mm space between them showed a maximum particle measuring efficiency. To apply this modified ISPM to semiconductor manufacturing field, we need more experiment about the pressure change, flow rate, and input particle size.
