Purpose: This research was, by investigating the relations between the cultural types of a nursing organization in military hospital and performance, to ascertain the cultural types to be able to improve performance. Method: The date were gathered from 255 nurse officers who were in 19 military hospitals by using the self-report type of questionnaire. The period of data collection was from April 20, 2003 to July 15, 2003. For this research, the following tools were used: the tools for measuring the organizational characteristics, organizational culture, and job satisfaction, the tool for measuring organizational commitment. For data analysis the SPSS Win 12.0 program was used. Result: 1) Most of the cultural types of a nursing organization in military hospital is Relation-oriented. 2) In the relation between general the characteristics of subject and the organizational cultural type, there was a difference in the innovation-oriented, relation-oriented, hierarchy-oriented, and task-oriented culture according to nurse officers careers, hospital types, year in hospital, marital status, and unit(p<0.05). 3) In the relation between general characteristics of subject and organizational performance, there was a difference in the job satisfaction, affective commitment, transactional commitment, and normative commitment according to nurse officers careers, education, madrigal status and unit(p<0.05). 4) In the relationship between the of a military hospital were correlated with the type of each culture(p=0.00), 5) In the relation between the organizational culture type of military hospital and its performance, there was a positive correlation among job satisfaction and innovation-oriented culture, relation-oriented culture, task-oriented culture(p<0.05). And hierarchy-oriented culture showed that they had a weak negative correlation with job satisfaction(p<0.05). There was a positive correlation among affective commitment and innovation-oriented culture, relation-oriented culture, task-oriented culture(p<0.05). And hierarchy-oriented culture showed that they had a weak negative correlation with affective commitment(p<0.05). There was no culture type significantly related to continuance commitment and there was a weak positive correlation among normative commitment and innovation-oriented culture, relation-oriented culture, task-oriented culture. The types to have an influence upon nurse officers' job satisfaction were relation-oriented culture and innovation-oriented culture(p=0.00). And relation-oriented culture and innovation-oriented culture were major variances for affective commitment and only relation-oriented culture was influential variance for normative commitment(p=0.00). Conclusion: The organizational culture type was found which had an influence upon nurse officers' job satisfaction and organizational commitment. These result are very significant in having showed the persons in charge of nursing administration a basic data for creation of an effective organizational culture.

Cost estimates are necessary for government acquisition program to support decisions about funding, to develop annual budget requests and to validate resource requirements at key decision points. Many researches have been done about cost estimating technique recently. Parametric cost estimating models based on CERs(Cost Estimating Relationships) have been mainly used using regression method with historical data. However, there are many restrictions in developing Korean version CERs because the number of data points are too small. Specially, data collection and data management system are unstable in Korean defense environment, when developing CERs. In this research, we analyzed the historical data, and found some cost drivers in guided weapon system area. We developed the Acquisition Unit Cost CER using the regression to remove multicollinearity in the historical data. So we could overcome the restriction of the insufficient sample number. This research as a first attempt is meaningful in terms of obtaining our own Acquisition Unit Cost CER using historical cost and physical characteristic in Korean development environment.

MIL-STD-461E, EMI military standard for the equipment and subsystems, requires reception characteristic tests to verify the susceptibility of a receiver against the jntermodulation and spurious signals. Because the CS103 and CS104 of MIL-STD-461E show the test configuration of the equipment unit like a traditional receiver, it is possible to verify the susceptibility only for the reception signal through analog filters. However, at present when software programming techniques make a progress, the CS103 and CS104 tests need to evaluate the reception signal of the subsystem which includes both the digital filtering effects and analog filter characteristics. These test and evaluation techniques applied to a surveillance radar subsystem. This paper researched the EMI test methods in order to confirm feasibility of these test and evaluation techniques. Also the test results are compared and analyzed.

In this paper, we have proposed hardware and software architecture of a launch control unit for the compatibility between air defense weapon systems loaded on shipboard. Until now, there is no compatibility between weapon systems loaded in battleships of korean navy. In the case of HaeGung system recently completed the test and evaluations, although it will be deployed on several kinds of shipboards, it has no compatibility and flexibility with other air defense weapon systems. Recently it reports that a long range air defense weapon system will be carried on future korean destroyer KDDX. Because the HaeGung and a long range air defense system will be operated together in KDDX, it is necessary to provide the compatibility between two weapon systems. So we have proposed architecture to provide the compatibility of the launch control unit that controls the launching system and the missile interface unit, and the missile in each weapon systems.

A series of experiments with a laboratory scale ultrasound treatment system for MTBE polluted groundwater was performed to increase the efficiency of MTBE degradation in groundwater. This study evaluated several factors to increase the efficiency of MTBE treatment for artificial and natural groundwater. The treated volume of groundwater, ultrasound frequency and power, and pollutant concentrations have been changed to evaluate its effects on the degradation efficiency of MTBE in batch and continuous flow reactor. For the specific experimental conditions on this paper, MTBE degradations are more efficient at 580 kHz than those at 1 MHz. The efficiency of MTBE degradation is proportional to the intensity of ultrasound power per unit volume of MTBE polluted groundwater. The concentration of ions in groundwater does not much affect the efficiency of MTBE degradation. The $1^{st}$ order degradation constant of MTBE for different power per unit volume at 580 kHz shows linear relationship at same concentration. The $1^{st}$ order degradation constant for 0.1 mM MTBE solution is higher than that for 1 mM MTBE solution. These experimental results could be helpful to seek optimal conditions for relatively large volume of polluted groundwater treatment.

최근 러시아·우크라이나 전쟁에서 볼 수 있듯이 군수지원은 현대전에서 빼놓을 수 없는 중요한 요소 중의 하나이다. 군수지원은 모의 논리의 특수성과 복잡성으로 인해 대부대 분석 모델과 전문적인 기능 모델 중심으로 발전되어 왔지만, 교전급 분석 모델에서는 군수지원에 대한 요구가 상대적으로 높지 않았다. 그러나 대대급 이하 제대에서도 무인 수송자산을 이용한 재보급 필요성이 제기되면서, 이의 전투 효과를 분석하기 위한 모의 기법도 함께 요구되고 있다. 이에 본 연구에서는 대대급 이하 제대의 탄약 재보급 논리를 기반으로 교전급 분석 모델을 위한 재보급 과업 모델을 설계한다. 재보급 과업 모델은 다음과 같은 순서로 도출되는 의사결정트리를 기반으로 동작한다. 먼저, 사전 반복 모의실험을 통해 여러 가지 쌍방 교전 조건과 아군의 탄 잔여량에 따른 피아 손실교환비를 수집한다. 이어서, 쌍방 교전 조건, 탄 잔여량, 손실교환비로 표현되는 의사결정 트리를 만든다. 의사결정트리는 전투모의 실행 간에 적의 위협 강도, 피지원 부대의 탄 잔여량 등을 고려하여 재보급 우선순위를 결정하는 데 사용된다. 끝으로 제안된 모델의 실행 가능성을 OneSAF 기반 소부대 전투 모의실험을 통해 입증한다.
