전방막사의 단열개수로 인한 에너지 소비절감 효과에 관한 연구
金錫蜂 陸軍士官學校 1986 한국군사학논집 Vol.30 No.-
The purpose of this study is to compare the thermal and economic efficiency between the existing military barracks of frontal area and those which retrofitted on the basis of energy conservation. The results are as follows; 1) According to the standard design of combined military barracks of the Army, the K value of the roof is 0.520, the K value of the out-wall is 0.526. They are even below the national standard level of isolation of heat. Therefore in order to qualify the national standard level, the thickness of polystyrenefoam should be changed from 50mm of the present to 75mm. 2) In case of existing military barracks, the heat loss per each column which is attached to the outer-wall is 102 kcal/h. But in the barracks which are retrofitted, the heat loss can be lowered to 24kcal/h. 3) In case of existing military barracks, the heat loss between the wall and the slab of the first floor is 32,000 kcal/h in total. But if we retrofit the barracks, the heat loss can be diminished up to 25%. 4) If we retrofit the barracks, not only the isolation level of heat would satisfy the standard level but also the cost of heating might be decreased to a great degree. Also, Since the cost of retrofit would be returned in about three years, we can say it is economically efficient.

So far, anti-piercing depths for concrete slabs have been determined using Conventional Weapon's Effects Program(CONWEP) that was developed by the U. S. Army's Corps of Engineering. However, it has been suggested by a number of field officers that the values computed by CONWEP tend to be too high for protective facilities used in small military units and that indiscriminate application of these values to such facilities would lead to uneconomical penetration-proof designs. In this study, gunshots onto RC slabs were carried out using KM80 bullets in order to measure the piercing depths. The observed depths and the depths offered by the CONWEP system differed greatly from each other by up to 119 centimeters. Based on the depth values obtained through this experiment, we have proposed a new equation to calculate effective anti-piercing depths for RC slabs against small caliber bullets.

In this study, the Indoor Air Quality(IAQ) in military barracks is evaluated and its characteristics is discussed as well. The military barracks of R.O.K Army are categorized into three types and the IAQ in these individual facilities is measured for 24 hours both in summer and winter. Test results show that the particulate matters($PM_{10}$) and carbon dioxide($CO_2$) were the main causes contaminating IAQ in military barracks. While $CO_2$ can be purified by ventilation, adequate facilities have to be installed in case of the new type of combination barracks to remove $PM_{10}$. In addition, to improve the living condition of military barracks and to recover IAQ in new combination style barracks which is planned to complete by 2011, a standard or law regulating IAQ in military barracks has to be established.

This study aims to examine the effectiveness of electromagnetic pulse shielding in cast-in-place protective shelters using corrugated metal-plates, and then reviews their usability for the Republic of Korea Army. The Korea Corps of Engineering has evaluated corrugated metal-plates as a construction material for cast-in-place structures, which have to defend against mechanical impacts as well as electromagnetic pulses. Corrugated metal-plate is known as a superb mechanical protective material, so much so that it has been employed in ammunition magazines and artillery platforms in the armed forces. Moreover, as a metal, such as steel and copper, it is universally recognized as one of the most effective electromagnetic pulse shielding materials. In addition to effectively shielding from electromagnetic pulses and protecting against mechanical impacts, corrugated metal-plates should prove to be an appropriate construction material for the cast-in-place protective shelter in terms of construction availability and economic feasibility. The shielding effectiveness of the suggested structures is examined based on MIL-STD 188-125-1. A few frequency bands need an increase of 15∼30dB in shielding effectiveness because of unbidden apertures caused by flaws associated with welding,assembling, and material deformation. However, allowing for the approximately 40dB of shielding provided by soil; the examined structure, which is buried underground, can offset its shortcomings sufficiently.

The current M3 rifle bipod developed for the M16 rifle is not highly compatible for rifles of a different caliber(barrel circumference) such as the K2. In addition, the M3's use of pincers results in frequent accidental detachment from the weapon, leading to a probable loss in carriage. Also, the fixed structure of the M3 makes it difficult to execute aimed shots shifting from left to right. The following research seeks to provide a new bipod which is ; easily attached to the M16 and K2, not easily lost in carriage, and effective for aimed shots against moving targets. In order to accomplish this task the subsequent research was accomplished to develop and test such a device. Based on this research, the following conclusion were obtained : First, based on the improved design, the new bipod has increased compatibility between the K2 and M16. Second, by improving the design, the new bipod is considered to be more effective in aimed shots against moving targets. Thus, the firing capabilities of individual automatic weapon marksmen are increased. Third, by using hook instead of pincers in connecting part, the probable loss is reduced. Furthermore, since the cost of the new K2 bipod is relatively low, in can be easily distributed throughout the Korean Army to not only squad level automatic weapon marksmen, but also to regular riflemen. If such additional supplies are provided, increased marksmanship can be expected.

In the military communication environment, it is very difficult to obtain clear voice signal due to the high level noise. The purpose of this study is to find out the best body spot to get the vocal chords signal by measuring the skin or the bone conducting vibrations of different body positions within the noise environment. Based on the experimental study, it was found out that the measurement of sound signal within the ear is the best way to get the voice which comes from the vocal chords and this method can prevent the interruption of noise. This study will give the effective voice communication method in the high noise environment and be applicable to military purpose.
