  • Although multi-frame super resolution algorithm has many merits but it demands too much calculation time. Researches have shown that image processing time can be reduced using a CUDA(Compute unified device architecture) which is one of GPGPU(General purpose computing on graphics processing unit) models. In this paper, we show that the processing time of multi-frame super resolution algorithm can be reduced by employing the CUDA. It was applied not to the whole parts but to the largest time consuming parts of the program. The simulation result shows that using a CUDA can reduce an operation time dramatically. Therefore it can be possible that multi-frame super resolution algorithm is implemented in real time by using libraries of image processing algorithms which are made by a CUDA.

  • Victory and defeat of the war depends on follow-on logistics support. The spending time of follow-on logistics support at combat area is greatly influenced by the degree of combat intensity. The main purpose of this study is to compose a optimal supply route for operational sustainability of combat unit at combat area using transport vehicles. This study suggests a composition of optimal supply route for follow-on logistics support which considers the degree of combat intensity. A mathematical programming model and a genetic algorithm suggest to minimize the total spending time of follow-on logistics support. The suggested mathematical programming model is verified by using CPLEX 11.1. This study computes supply route, total spending time, total travel distance, and the number of transport vehicle.

  • This study was performed to investigate the sanitation management and the sanitation knowledge of managers in military foodservice by questionnaires and inspection of foodservice facilities. Thirty managers working in military foodservice were given questionnaires and the related facilities located in the northern part of Kyeongki-Do, Korea were inspected. Most of the facilities(76.%) were built more than ten years ago, they are now decreptit and the internal temperature was high with poor ventilation in the kitchen. An education program on sanitation was conducted less than four times a month (63.3%) while the education materials and resources from the upper-unit(80%) along with their self-renewment of data was poor(once a month, 60%). In the sanitation knowledge examination, the percentage of correct answers were 76% in terms of facilities, 72% in terms of personal sanitation, 71% in terms of receiving and storage, 63% in terms of the environment and 57% in terms of the cooking process. The results of this study suggest that the modernization of foodservice facilities and equipment, along with additional sanitation machinery and equipment, a guaranteed working environment and upgraded sanitation education will be required to improve the sanitation management in military foodservice.

  • In general, radial velocity of a target can be obtained by acquiring doppler frequency shift in case of a doppler radar, or can be obtained by acquiring range rate in case of a pulse radar. Then radial velocity can be converted to tangential velocity using aspect angle or position variation per unit time. These two ways have the same meaning in physically, but result in different uncertainty finally. In this paper, it is described not only the two transformation procedures to calculate tangential velocity from radar measurement data, but also the result of combined uncertainty comparison between these two procedures.

  • This paper presents the simulation model to decide the mean size of cannibalization aircraft (MSCA) under steady state when an airbase makes use of cannibalization to support the spare parts of an airfleet. In this model, the essential factors such as mission requirements, mission time, failure time, repair time, repair capability, inventory policy, cannivalization rule are considered. The model is constructed with above factors and actual airbase operating rules for a basis. Because of the tangled interdependencies among the each factors, it is inevitable to construct the model by the simulation technique. The mission and support system of the airbase is considered as a closed queueing network with a finite number of unit The troubled aircrafts are repaired in accordance with the priorities that are determined by their repair times. The illustrative example of the model, using the actual data of xx-airbase, is presented. The model would be a useful tool not only to determine the MSCA and the size of scheduled maintenance aircraft but to evaluate the NORS (not operationally ready supply) rate and the availability of an airfleet.

  • Weapon System effectiveness indices are a key factor to the cost-effectiveness analysis in the process of allocating national resources in an optimal fashion. First part of this paper reviews the need of weapon -effectiveness indices, historical development of methodologies on military strength evaluation with various models of indices, and the interrelation-ship between weapon effectiveness indices and war-game. Second part of this paper analyzes the concepts and usage of the already developed methodologies, i .e., index of power, weapon lethality index (W.L.I.), index of fire power potential (I.F.P), fire power potential (F. P. P), and weapon effectiveness indices/weighted unit value (W. E. I/W. U. V.). Finally, weaknesses and limits of these methodologies are compared and evaluated. Result of this research shows that the W. L. I, I. F. P, and F. P. P seem to possess many non-scientific or ambiguous facets, but the W. E. I/W. U. V method produces more detailed, inclusive, and reasonable indices. The paper concludes with the emphasis on the importance of the provision of the theoretical bases to develop effectiveness indices which can be used to evaluate Korean weapon systems, and the early establishment of a specialized research group to manage and develop methodologies on the weapon effectiveness indices.

  • Namhansanseong fortress (南漢山城) is not Eupchi (邑治) created for ages but the new settlement of public and military administration as Baedo (陪都) to defend capital territory. Namhansanseong has Jinsan (鎭山) that is named Cheongnyangsan (淸凉山) and its government office building was located in the main place, also a periodic five-day market was being held in the center of fortress. This study is find out the transition and its historical background of government office building on Namhansanseong by the relocation of Eupchi in the 17th century. The conclusion of analysis can be summarized as follows; The main change of government office in the late Choson dynasty is to move Yi-a, administrative complex (貳衙) around Yeonmugwan (演武館). Since 1795, the 19th year of King Jeongjo (正祖), this was fixed by the end of the Choson dynasty on the unification of Magistrate which is also Defense Commander. In the second place, the military office on Jungyeong (中營) that is Junggun's (中軍) place of work was abolished by the reform of Junggun system. Thirdly, transition of the end of the Choson dynasty is the abolition of Sueoyeong (守禦營) and the realignment of government offices. Namely, the administrative agency was moved to Haenggung (行宮) after the collapse of unification in 1895. Also former military offices was changed to police administration on Gwangju-bu (廣州府), Gwangju county level unit.

  • A cylinder-type underwater vehicle for military use that is running near the free surface at the final homing stage to hit a surface ship target is affected by wave force and moment. Since wave can affect an underwater vehicle running at the depth less than half of the modal wave length, it is important to confirm that the underwater vehicle can work well in such a situation. In this paper, wave force and moment per unit wave amplitude depending on wave frequency, wave direction, and vehicle's running depth were calculated by 3-Dimensional panel method, and the numerical results were modeled in external force terms of six degrees of freedom equations of motion. Motion simulation of the underwater vehicle running in various speed, depth, and sea state were performed.

  • The purpose of this descriptive study was to assess sexual orientation and Knowledge and attitudes with regards to AIDS in military personnel, and to provide basic data for developing a further sex education program for them. The data were collected in June 2002 on 242 service members of A Branch of the Ground Army located in Chung-Chung Do Region. They responded to a survey questionnaire that consisted of 68 items: 14 items on sexual orientation. 39 items on knowledge about AIDS, and 15 items on attitudes toward AIDS. The data were analyzed using SAS program. The study results are as follows: 1. Sexual orientation of the military personnel 1) In terms of sexual orientaion, harassment and assault, only $26.4\%$ of the subjects responded as, 'know well'. Appropriate awareness of the legal liability was reported by $21.6\%$ of the subjects regarding sexual harassment and $78.1\%$ of the subjects regarding sexual assault. 2) Pre-marital cohabitant was supported by $89.2\%$ of the subjects. 3) The Korean military personnel showed liberal attitudes toward sexuality as $46.4\%$ of them reported having sexual-relationship with the dating partner is acceptable. 4) The attitudes of the most subjects toward homosexuality was found to be unfavorable. 5) Subjects were m the need of appropriate sex education. of which substantial knowledge on sexual intercourse was the most needy area. 2. Knowledge and attitudes toward AIDS of the military personnel 1) The subjects' level of knowledge on AIDS was relatively low, showing the average score of $22.31\pm7.23$ points (range: 0-39 points). The higher level of knowledge was reported by those who had high level of education, father alive. and less number of brothers in their family. 2) The subjects' attitudes toward AIDS was relatively positive. The attitude toward AIDS was also found to be more positive in those who had high level of education and less number of brothers. 3) There was a positive but weak correlation between knowledge and attitude toward AIDS. The study finding showed that the sexual orientaion of the Korean military personnel was moderately positive and liberal. However, their awareness of sexual harassment and assault and AIDS was still found to be low. As Korean enlisted military service men are likely to be in the ages with strong sexual desire, it may be important for them to have appropriate sexual orientation and attitudes toward AIDS. Therefore, it is recommended to develop further practical and sound sex education programs within the military unit in order to meet their education needs as well as to utilize sex education specialists as the instructors of those programs.

  • Software system is a hierarchical structure with collection of program units. Software system can import external packages globally or locally depending on the usage within a system. If the imported package is used globally, the soft-ware system can be influenced globally by any change of package and programmer's debugging time for the program maintenance will be greater. To solve these problems, it is desirable to use the imported package locally right on the usage point within the system. The model presented in this paper analyzed entity usage of package in structure of program, identified the usage level to obtain localization and provided information for restructure of the program to localize package usage. To obtain localization, it identified declared entities inside the imported package and analyzed the specification and body part of program unit to identify entities referenced from the imported package. The proposed model can be used to improve the maintainability of software system and contributed to reduction of programmer's debugging time in program maintenance.
