The military is facing an era in which it must take advantage of technologies related with the 4th Industrial Revolution. The representative of the final application of the 4th Industrial Revolution technology is the unmanned system. Many unmanned systems have not yet been harnessed to the army, and it is assumed based on literature studies that improving familiarity with unmanned systems will have a positive effect on force strength in the future. To verify these assumptions, the structural equation model(SEM) was used for quantitative analysis. The results suggest that the increase in familiarity with unmanned systems induces the increase in availability of unmanned systems in each field, which eventually raises the expectation that overall ground force strength will increase. These results imply that the military should reinforce the curriculum that enhances the familiarity of the unmanned system in military education system.

The purpose of this research is to develop a conceptual model that establishes a new approach for functional area cost estimating in the schematic design phase. A cost estimating model should consider not only the estimate accuracy, but also the flexibility to the design alternatives and user-oriented serviceability. Therefore, this research uses the method that classifies various facilities of a building according to its functions by analyzing historical data. After setting the functional area as cost parameter, a formula which can estimate functional area cost is derived from statistical analysis. Finally, to validate the proposed conceptual model, it is applied to historical data of a military barrack project. It enables customized space planning reflecting client's needs and compares the cost of various design alternatives as well as improves estimate accuracy.

In the rapidly changing current society, the Korean National Police(KNP) is facing a lot of demands from the citizens like the protection of subject/victim rights, independence of investigation authority, disclosure of actual truth, and prevention & eradication of crimes. It is widely recognized among the Korean people and the police that the KNP is always standing for the rights of the people and it is high time that the KNP should be restored as the pioneer for the protection of human right. In this situation, the tremendous emphasis is given on the importance of investment in investigative training through the long-term master-plan in order to renovate its constitution, to level up its quality, and to cope with the highly sophisticated crime patterns. Korean police have already shown its outstanding investigative skills of identification of the deceased throughout large cases like Daegu subway arson and tsunami in Southeast Asia. In addition, the skills of cyber crime investigation are highly recognized by foreign law enforcement agencies. However, the investigative skills and abilities are being degraded and the morale of the investigative personnel are falling due to the insufficiently of the finite training budget. Lack of financial support results in the lack of training program and poor training environment, which subsequently leads to the inefficiency of training. Additionally, no long-term budget for fostering specialized investigative agents is allotted. Considering the fact that more than 95% of crimes in Korea are being primarily investigated by the Korean police, we have to understand the importance of the police. By the tremendous investment in investigative training which can lead to the high-quality investigations, the Korean police can ultimately contribute to the protection of safety and life of its people.

In this paper, a method of generating path planning map is developed using digitalized geographic information such as FDB(Feature DataBase). FDB is widely used by the Army and needs to be applied to all weapon systems of newly developed. For the autonomous navigation of a robot, it is necessary to generate a path planning map by which a global path can be optimized. First, data included in FDB is analyzed in order to identify meaningful layers and attributes of which information can be used to generate the path planning map. Then for each of meaningful layers identified, a set of values of attributes in the layer is converted into the traverse cost using a matching table in which any combination of attribute values are matched into the corresponding traverse cost. For a certain region that is gridded, i.e., represented by a grid map, the traverse cost is extracted in a automatic manner for each gird of the region to generate the path planning map. Since multiple layers may be included in a single grid, an algorithm is developed to fusion several traverse costs. The proposed method is tested using a experimental program. Test results show that it can be a viable tool for generating the path planning map in real-time. The method can be used to generate other kinds of path planning maps using the digitalized geographic information as well.

The purpose of this study is to investigate the developmental process of University-based librarianship education in Japan from a historical perspective by analyzing literature. The results show that America's librarianship education policy historically focused on the establishment of a new model of librarianship education whereas Japan's policy was to keep the one from the Second World War. In 1951, an American model of education was established at Keio University by the contract between U.S. Department of the Army and American Library Association in America, but it did not continue to develop as mainstream model. The American model of librarianship education was not successful in Japan. It is expected that this study concerning Japanese librarianship education which adopted by the American model at the first time after the war in Asia will give vision for further studies in the domain of library history.

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.

Purpose: Various treatment methods have been utilized for recurrent dislocation of the TMJ (temporomandibular joint). The purpose of this study is to define the effect of the eminectomy with discoplasty that had been performed in patients with TMJ luxation. Materials and Methods: Twenty patients (22 joints), whose diagnosis were TMJ dislocation were selected in 772 patients (871 joints) who had been underwent TMJ surgery between 1988 and 2000. The selected patients were divided into two groups. Group I (12 joints) was the habitual-luxation group which involves the recurrent TMJ dislocation patients. Group II (10 joints) was the open lock-history group which involves the patients who had more than two episodes of TMJ luxation and TMJ disorders. The history of TMJ luxation, maximum mouth opening and other TMJ signs and symptoms before and after surgery were reviewed. Results: In group I, one patient who had been underwent both TMJ operation had a intermittent locking, but it disappeared after post-operative 32 months. In group II, intermittent pain was present in one patient who had bruxism, but it was disappeared by splint therapy. No more TMJ dislocations and other pains were checked in other patients of group I and II. Conclusion: Eminectomy with discoplasty may be used to successfully treat the TMJ habitual luxation accompanied with abnormal condition of the disc-condyle complex.

Korean army has been trying to construct a future tactical network in collaboration with TICN at the ground level and the next-generation military satellite system in the space level. However, due to the low bandwidth and high operational cost, the satellite system has the limitation to exchange all kind of tactical information through it. To overcome the limitation, there have been several researches to construct airborne networks. In this paper, we propose an effective interworking architecture and operation scheme between terrestrial tactical networks and aerial relay networks to counteract against the communication breaks of terrestrial terminals. And, we also propose a way to analyze its effectiveness. The experimental results show that the interworking of aerial relay networks can manage the failure situations in terrestrial tactical networks very effectively.

Flavin adenine dinucleotide-dependent glucose dehydrogenase (FAD-GDH) can utilize a variety of external electron acceptors and also has stricter substrate specificity than any other glucose oxidoreductases, which makes it the ideal diagnostic enzyme in the field of glucose biosensors. A gene coding for a hypothetical protein, similar to glucose oxidase and derived from Aspergillus terreus NIH2624, was overexpressed in Pichia pastoris GS115 under the control of an AOX1 promoter with a level of 260,000 U/l in the culture supernatant after fed-batch cultivation for 84 h. After a three-step purification protocol that included isopropanol precipitation, affinity chromatography, and a second isopropanol precipitation, recombinant FAD-GDH was purified with a recovery of 65%. This is the first time that isopropanol precipitation has been used to concentrate a fermentation supernatant and exchange buffers after affinity chromatography purification. The purified FAD-GDH exhibited a broad and diffuse band between 83 and 150 kDa. The recombinant FAD-GDH was stable across a wide pH range (3.5 to 9.0) with maximum activity at pH 7.5 and $55^{\circ}C$. In addition, it displayed very high thermal stability, with a half-life of 82 min at $60^{\circ}C$. These characteristics indicate that FAD-GDH will be useful in the field of glucose biosensors.
