Weapon systems' required operational capability (ROC) is an important factor that determines the success of a new weapon system for performance and acquisition. Excessive ROC can delay a project or cause failure, while if it is too low, it can lead to technology obsolescence. Therefore, in order to successfully acquire new weapon systems, a single or evolutionary acquisition strategy must be determined based on the ROC. The purpose of this study was to analyze the causes of ROC correction by identifying 160 cases in the last 10 years (2011-2020). Then, 'evaluation item index' to apply to the evolutionary acquisition/ROC of a new weapon system project was developed, and the weight (importance) and priorities were determined through an analytic hierarchical process (AHP). The main correction causes were classified using 6 categories, and the most frequent one was the difficulty of predicting the technology level (41%). There are 8 evaluation item indexes based on the correction causes, such as "technical readiness level (0.428)" and "military force delivery time (0.128)," which have high weights. The "evolutionary acquisition/ROC evaluation item index" presented in this paper is expected to help with rational and scientific decision-making during the review process to apply evolutionary acquisition strategies and contribute to successful weapons-system acquisition projects.

Heaters using the resistance heating principle are used in various industrial fields that require heat and are also essentially used in bidet among small home appliances. A planar heater and a coil-inserted heater mounted on a conventional commercially used bidet have disadvantages and limitations of complicated manufacturing process and local heating. In this study, silver-palladium (Ag-Pd) powder material was used for a screen-printing process that is more advantageous in achieving simplification than the existing process, and a rod-type heater for bidet was manufactured. The on-off cycle test under actual conditions was conducted to confirm the durability and the capability of the fabricated heater, and the fabricated heater operated more than 2,600 on-off cycles, which means it could be applied for a commercial product. In addition, through the on-off cycles under harsh conditions, the cause of failure was identified after the test that the durability limit temperature of the heater was 850℃. Through Ag-Pd rod heater in this study, it is expected to contribute to the efficient development of electrode materials for heaters and the improvement of the durability of heaters in the future.

Intravesical instillation therapy with anticancer drug is regarded as one of the ideal therapies against bladder tumors of superficial, multiple and relatively differentiated type. There was a variety of factors which limit the anticancer agents suitable for intravesical instillation therapy. However Doxorubicin hydrochloride, a new anticancer drug isolated in 1967 from a mutant of streptomyces peucetius, was found to be effective for the treatment of Superficial bladder cancer and it is considered the most suitable for this type of treatment, because fo the following characteristics: it is sensitive to transitional cell carsinoma, it is a dose-dependent agent, it has strong affinity to tissues, and its transfer from body cavities into the blood is negligible. The local recurrence has been a matter of problem in the treatment of well-differentiated bladder tumor. Instillation of anticancer agents to the bladder has been tried to control bladder tumor itself as well as the local recurrence. This drove us to study the effects of intravesical instillation of Doxorubicin hydrochloride to 49 patients with bladder tumor from view points of therapeutic effects on the tumor present and also prophylactic effects of preventing recurrence of tumor. And the results were analyzed and concluded as follows: A. Therapeutic group 1. There were 20 males and 2 females. The average age was 56.9 pears, ranging from 39 to 77. 2. All these patients had transitional cell carcinoma: there were 5 of grade I, 13 of grade Ⅱ, and 4 of grade Ⅲ tumors. The disease was classified as stage A (T1) in 10 case;, stage B1 (T2) in 9 cases, stage B2 (T3) in 2 cases, and stage C (T3) in 1 case. There were 17 cases of papillary-type tumors among them. Seven patients had solitary tumors and the remaining 15 cases had multiple lesions. 3. 60 mg of Doxorubicin hydrochloride dissolved in 30ml of physiological saline was instilled through a Nelaton catheter transurethrally. The drug was retained for more than 2 hours and the treatment was repeated daily on 3 consecutive days followed by a 4-day interval, for 3 weeks. 4. The therapy was markedly effective in two cases and effective in 12 cases, while in 8 cases it was ineffective. The effectiveness rate was 63.6% 5. Treatment of bladder tumors persisting after cessation of Doxorubicin hydrochloride was needed in most cases. TUC or TUR was performed in 14 cases including 1 in which the therapy was markedly effective, 9 in which it was effective, and 4 in which it was ineffective. Segmental resection of bladder was performed in 6 cases, including 3 in the effective and 3 in the ineffective group. Most cases required surgery or radiation after instillation treatment; surgery was easily performed because the tumor size had been reduced and the loss of blood during the sugery was relatively small amount. B. Prophylactic group 1. There were 24 males and 3 females. The average age was 61.1 years, ranging from 42 to 75. 2. All these patients had transitional cell carcinoma: there were 9 of grade I, 14 of grade Ⅱ, and 4 of grade Ⅲ tumors. The disease was classified as stage A (TI) in 15 cases, stage B1 (T2) in 9 cases, and stage B2 (T3) in 3 cases. There were 22 cases of papillary-type tumors among them. Sixteen patients had solitary tumors and the remaing 11 cases had multiple lesions. 3. 30mg of Doxorubicin hydrochloride dissolved in 30ml physiological saline was instilled through a Nelaton catheter transurethrally. The drug was retained for more than 2 hours and the treatment was repeated daily on 2 consecutive days followed by a 5-day interval, for 4 weeks. 4. Follow up study at 3-month interval has shown excellent control of tumor recurrence with complete :emissions for upto 24 months or more in 2 cases. The recurrence was not observed in 18 cases, but it occurred in 9 cases. The control group showed a recurrence rate of. 83.3% while the group, in which prophylaxis performed with Doxorubicin hydochloride, showed a recurrence rate of 33.3% The median for recurrence in prophylactic group was 9.2 months and in control group, 6.55 months. C. Side effects No systemic side effects were noted in any of our cases. Local adverse effects such as bladder irritability were encountered in 5 cases of therapeutic group and 6 cases of prophylactic group.

Secure and seamless communications between the forces deployed in battlefield are utmost important for success of the military operation. Numerous back-up communication systems are prepared in military in order to enhance the communication requirement of the military. The basic military communication network is classified into two main categories in Korea; fixed communication network and mobile network system. The fixed network system includes M-BcN, Leased commercial communication network and Micro-Wave network, SPIDER, TICN, Satellite communication system, combat radio system are the elements of the mobile communication network system. In this research, the propriety of current communication system of ROK Army is studied. It is discovered that some elements of the system are needed to improve in order to enhance essential military command & control capability. Current military communication system is suitable for voice communication, but is not fulfill the demand for data communication in military. Moreover it is also required to prepare future communications system which will be used in the next generation scientific warfare. This paper demonstrates directions for developing future military communication system in order to maximize its operational capability. Since it is essential to provide DATA communication along with voice communication in military acquiring and fielding multi-purpose tactical radio system for all the operation units is the very first project need to be accomplished. For the military communication network system, it is required to construct All-IP based unified network system by integrating the fixed network system and the mobile network system. 군사작전의 성공을 위해 전장에 전개된 부대 간의 보안이 확보된 원활한통신은 가장 중요한 요소이다. 이에 우리 군(軍)은 통신능력을 강화하기 위해 여러 기반통신망을 상호보완적으로 운용하고 있다. 군(軍)의 기반통신망은 고정통신망과 기동통신망으로 분류된다. 고정통신망에는 국방광대역통합망(M-BcN), 임대정보통신회선, 마이크로웨이브(M/W)가 있고 기동통신망에는 전술통신체계(SPIDER), 전술정보통신망(TICN), 군(軍)위성통신체계, 전투무선망이 있다. 본 연구에서는 한국군 지상군을 중심으로 기반통신망을 분석하여 문제점을 식별하고 미래전장 환경에 대비하기 위한 발전 방향을 제시한다. 현(現) 기반통신망은 군(軍) 통신환경 변화 대비 대용량 데이터 전송 제한, 상호운용성 부족 등 문제점이 식별된다. 기반통신망의 능력을 향상하기 위해수용성, 생존성, 통합성, 신속성, 보안성, 신뢰성, 상호운용성 측면에서 개선 및 보완되어야 한다. 중기적으로 각각의 기반통신망은 공통의 IP 기술을 기반으로 발전되어야 하고, 장기적으로 고정통신망과 기동통신망은All-IP 기반 단일 통합형 네트워크 형태로 구축 발전시켜야 한다.

Capacitive-type humidity sensors with a high sensitivity and fast response/recovery times have attracted a great attention in non-contact respiration biological signal monitoring applications. However, complicated fabrication processes involving high-temperature heat treatment for the hygroscopic film is essential in the conventional ceramic-based humidity sensors. In this study, a non-toxic ceramic/metal halide (BaTiO3(BT)/NaCl) humidity sensor was prepared at room temperature using a solvent-free aerosol deposition process (AD) without any additional process. Currently prepared BT/NaCl humidity sensor shows an excellent sensitivity (245 pF/RH%) and superior response/recovery times (3s/4s) due to the NaCl ionization effect resulting in an immense interfacial polarization. Furthermore, the non-contact respiration signal variation using the BT/NaCl sensor was determined to be over 700% by maintaining the distance of 20 cm between the individual and the sensor. Through the AD-fabricated sensor in this study, we expect to develop a non-contact biological signal monitoring system that can be applied to various fields such as respiratory disease detection and management, infant respiratory signal observation, and touchless skin moisture sensing button.
