This research is focused on the development of protecting system for window. In detail, we tried to develop pollution preventing system of a glass, mirror, or camera lens. For this, the new method for efficient pollution prevention was designed and the characteristic evaluation for developing the system is partly performed. Formerly, the method using air purge is generally used for preventing the pollution of camera window. However, the conventional method often induces contaminations due to back flow of air purging. These pollutants can be crucial damage to the camera window and peripheral materials especially in clean room condition. And the conventional method always requires air supply, therefore it is difficult to apply the method where air source can not be supplied such as traveling crane located at mountain altitudes. To solve above mentioned the problem, the efficient concept for preventing pollution of camera window is proposed in this research. Without air purging, we proposed the new method using repulsion induced by electrifying dirty or moisture to positive magnetic force with high-voltage charge and then injecting gas to the ITO(Indium Tin Oxide) coating window for generating positive ion. To sum up, in this research, we aim to develop an efficient pollution preventing system for camera window based on the new method through characteristic evaluation and stabilization of the designed system.

Abstract Background Caudal block is widely used in paediatric anaesthetic practice. Many angles for needle insertion were compared to find a optimal angle during caudal block with high successful caudal injection and minimal risk of complications. The aim of this study is to evaluate the safety and effectivity of a new method of needle insertion at an angel of 90°to the apex of the sacral hiatus for caudal block in newborns. Methods Sixty patients were included in our study, aged 0 to 28 days, posted for inguinal hernia surgery, randomly divided into two groups: a conventional method (CM) group and a new method (NM) group. In both groups, 1 ml∙kg-1 0.5% lignocaine at a rate of approximately 0.5 ml∙s-1 was given for caudal blocks after anaesthesia, and ultrasonographic observation of local anesthetic in the epidural space. Failure rate at the first attempt, puncture frequency, complications, and durations of block were recorded. Results The failure rate at the first attempt of caudal block were 16.7% in the conventional method group and 3.3% in the new method group (p<0.05). The mean time required (standard deviation) to perform needle insertion in the conventional method group was 2.6±0.5 minutes and in new method group 1.6±0.5 minutes (p<0.05). There were three cases aspirating the needle to find blood and one case to find cerebrospinal fluid in the conventional method group. The majority level which the local anesthetic reached are L1 by ultrasound imaging, 86.7% in the conventional method group and 83.3% in the new method group. Conclusion The study found that using the new method, the chance of performing a successful caudal injection can be increased, the time and the risk can be minimized compared to conventional technique. It is a safe and effective method.

A new method on examining the micro cracks of monocrystalline silicon during nano indentation is proposed. It is established based on a study of the increasing rate of absorbed energy in nano indentation. This method provides a simple approach in understanding whether cracks on the silicon surfaces occur, while it is tedious in conventional method.

The conventional method of making velocity surveys in bore holes is inherently expensive, time consuming, and inconvenient, and has a tendency towards non‐uniformity of results. With increasing recognition of the importance of seismic velocity information in the evaluation of seismograph data, the attention of geophysicists is turning towards means of overcoming the obstacles standing in the way of obtaining velocity information in greater volume. Considerable interest has recently been aroused in a new method of measuring seismic velocities wherein the explosive charge is placed in the hole and the seismic energy is picked up with multiple detector groups placed on the surface. Experimentation carried on during the past year indicates that the new method is quite workable. Casing perforator guns of the conventional bullet type have given results to depths exceeding 8,000 ft. with complete safety. Some experimentation with primacord as the explosive has given encouragement as a means of increasing the depth at which the method may be used. Substantial improvements have been made in the manner of obtaining the time break. This paper attempts to outline the basic problems of velocities and their measurement and describes the preliminary development that has been done thus far on the new method of velocity measurement.

Through analysis of the vibration characteristics of 1000mm2 Large Section Conductor and test on the Anti-vibration effect of the vibration damper, a kind of method to determine the installation location of the vibration damper for 1000mm2 large Section Conductor by Simulation test is put forward. Compared with the conventional method, the protected span of the damper which installation location is determined by the new method is larger. This method will have guiding significance for the anti-vibration of the large section conductor.

Stereo vision and 3D reconstruction technologies are increasingly concerned in many fields. Stereo matching algorithm is the core of stereo vision and also a technical difficulty. A novel method based on super pixels is mentioned in this paper to reduce the calculating amount and the time. Stereo images from University of Tsukuba are used to test our method. The proposed method spends only 1% of the time spent by the conventional method. Through a two-step super-pixel matching optimization, it takes 6.72 s to match a picture, which is 12.96% of the pre-optimization.

An improved 24-hour hydrophobic grid membrane filter HGMF method for coliform and Escherichia coli enumeration was developed. The new method, which uses a buffered MUG agar for the E. coli portion of the test, was subjected to a precollaborative validation study against the 3-tube MPN procedure encompassing 375 naturally contaminated and inoculated samples representing 25 food products. The HGMF/MUG method produced coliform and E. coli counts equivalent to the conventional method. The confirmation rate of MUG-positive colonies in this study was 98.1%.

Stationary Period

A method is described whereby enterovirus present in a 5-ml liquid sample may be efficiently recovered for plaque enumeration on a single 60 × 15 mm culture dish. Adsorption is accomplished by constant agitation of the sample with suspended cells followed by a stationary period to allow monolayer formation for plaque development. Comparative studies with the use of coxsackievirus B5 and poliovirus 1, on HEp-2 and Vero cells respectively, indicated that the conventional method of adsorption onto stationary monolayers would require 50 times as many dishes and cells for an equal efficiency. The new method might be useful for the recovery of small numbers of viruses from food or water samples providing they are nontoxic to cells and contain no bacteria.
