A Technical Manual is the tool that offers a guidance to a maintenance engineer in order to exactly use and maintain of complicated weapon system. Because the modern weapon system are complex and functionality integrated, its quantity is massive. So We spend a lot of money on its publication and suspending recent information. To solve this problem, to reduce a risk of loss and use easily, this study develops the IETM(Interactive Electronic technical manual) which observes the CALS standard. This paper provide the development concept, environment, technic of IETM.

Mixed acid is very reactive and highly corrosive. it has been causing many accidents in a electronic industry, a steel industry, and a chemical industry. Therefore, it is required that the high safety level for the acid storage facilities. In this study, we investigated the accident causes for resent leak accidents with Root Cause Analysis (RCA). The root causes analysed by RCA were categorized as nine divisions by the their characteristics. Furthermore, each nine divisions causes was applied to the PDCA model which are using at OHSAS 18001. It is suggested that the nine division with the root causes can be the essential items for the development of the safety management manual. It is helpful to the safety improvement of the acid storage facility.

Recently Australian records system is been attention in archival area. We can recognize there are two reasons in it. Because it suggested DIRKS that is a development methodology of electronic records management system and the other hands it introduced the concept of functional provenance which overcomes the previous organizational one. It has very special meaning in Korea that have high level on IT industry in the world. Korean records management system succeeded to a certain extent but still has limitation on the application of description standards or metadata standards. This paper is going to introduce DIRKS, is the one of development methodology of Australian system, and try to apply it practically. Therefore, it will be helpful to people can easily understand DIRKS and it will add more explanation for practical operation.

As the speed of memory is improved vey fast the advanced test equipments are needed to test the ultra-high speed memory devices efficiently. It is necessary to develop the Algorithmic Pattern Generator (ALPG) that tests fast memory devices effectively using the instructions that testers want to use. In this paper, we propose a new parallel ALPG for the ultra-high speed memory testing. The proposed ALPG can generate patterns for fast memory devices at high speed using manual instructions by the Instruction Analyzer.

Electronic Toll Collection System (ETCS), so called "Hi-Pass" in Korea, has improved traffic flow at toll gate of highways. It is known that the improvement of traffic flow should reduce air pollutants and $CO_2$ from vehicles. In this study, real driving emission of a light duty truck with Portable Emission Measurement System(PEMS) has been measured to evaluate the emission reduction effect due to ETCS. The correlations between driving variables and emissions have been analyzed to verify its effect on traffic flow improvement and emission reduction at toll gate. We considered average vehicle speed, Relative Positive Acceleration (RPA), and the distance of queue as driving variables. Compared to passing Manual Toll Collection System (MTCS) lane without queue, ETCS was able to reduce 38.7% of $NO_x$, 21.6% of soot, and 27.7% of $CO_2$. The results showed that the higher the average vehicle speed, the lower RPA and no queue in ETCS contributed to the emission reductions. Linear equation models with RPA and queue have been established by the multiple linear regression method. The linear models resulted in the higher coefficient of determination than those with only average vehicle speed used for establishing vehicle emission factors.

With the development of the automobile industry, technologies for parts of an automobile with more convenient functions have progressed, but the manual clutch developed at the first phase of inventing means of transport still remains at the early stage of the automatic transmission despite numerous research and efforts. The traditional automatic transmission is mainly used in small cars and personal RV vehicles that include the slipped clutch disk. However, this research seeks an innovative technology that can be applied to all types of transportation operating the clutch, such as small cars, large vehicles, farm machines and vessels. In order to accurately decide the joint timing of the clutch disk according to the output of engine power that differs depending on driving conditions of vehicles, and to apply the half clutch state which frequently occurs in the manual transmission, the rpm of the engine can be used as the base to decide the joint timing of the clutch disk. This research has developed an electronic clutch module that can transmit the engine power by moving and jointing the clutch disk as much as the engine rpm increases.

This paper describes the improvement of driving stability and the control system for INMEL-VII which is motorized manual wheelchair to satisfy requirements of the disabled The INMEL-VI was based on high maneuverability of the omnidirection drive and safety But the results of field tests about two years showed some problems to the disabled in daily life such as driving stability, Pm switching noise, and rotation of motor without driving command on negative slope. To solve the problems due to an increased DC motor power and applied to direct connection method in INMEL- VII. It improved the driving circuits and set switching frequency to 5KHz to eliminate the switching noise caused by PWM control of DC motor, As compare with the INMEL-VI, INMEL-VII is improved in driving stability by transfer the weight center to forward. The results of field testing proved the improvement of the driving stability and software algorithm It has been estimated to have a hlgh practical use for powered walking aids to the disabled's daily life.

Objectives This scoping review aimed to investigate the domestic clinical research trends of motion-style acupuncture treatment (MSAT), identify diseases and symptoms for which MSAT is used, summarize specific methods of MSAT, and suggest the direction of future studies. Methods The study was conducted in accordance with a previously specified methodology, using the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) checklist. We searched nine electronic databases for studies on MSAT reported till March 21, 2022. The search terms were 'kinematic acupuncture,' 'MSAT,' 'motion style acupuncture,' and 'motion style treatment.' Results A total of 29 studies were included in our analyses; of them, 23 (79.3%) were before-after studies. Lumbosacral disease was the most common for which MSAT was applied (n=16). The frequency and duration of treatments differed depending on the researchers, and local acupoints (including ashi points) were used in 22 (75.9%) studies. In most cases, the method of mobilizing the joint or stretching the muscle in the disease area was used after inserting the acupuncture; however, in 7 studies, gait exercise was used. Most studies used MSAT in combination with other treatments. Conclusions This study supports the direction of future research by presenting the methodological applications of MSAT. To increase its clinical applicability, studies with a high level of evidence investigating the application to various body part, standardization and safety of MSAT are necessary.

Global competition of automotive market and affordable prices of electronic components become the major reason that automotive industries rapidly employ a large number of electric and electronic systems to improve vehicle performance and to meet various regulations such as emission, fuel efficiency, and safety. Especially, the provision of a motor-driven steering column (MDSC) for luxury vehicle is getting popular for drivers' convenience. In this study, an MDSC is developed, which provides several intelligent features such as the manual operation for tilting and telescoping the steering wheel, and the save/recall operation for three different steering wheel positions. In addition, the fault detection algorithm is developed.
