The purpose of this study is to verify the relationship between mission-oriented Command, organization efficiency, organization culture of 626 field officers in JFMU. Firstly. the study found that decision making in the relationship between mission-oriented command and organization efficiency had negative effect on job satisfaction. Planning and trust lead to positive effect on job satisfaction and organizational commitment and no significance in self decision. Secondly, mission-oriented command may differ depending on the types of organization culture and organization culture has positive effect on job satisfaction and organizational commitment. Thirdly, mission-oriented command has some effect which derives from its impact on organization efficiency that also effects rational culture and rank hierarchy culture. These study results suggest different measures in terms of practice and policy. Firstly. within the military organization, precise communication will lead to job satisfaction without unnecessary overload of communication. Also. we have rationale culture, agreement culture and rank hierarchy culture forming our organization culture. There is a need to apply elements of mission-oriented command depending on the types of organization culture. Secondly, to maximize organization performance through mission-oriented command, we have to strengthen the rationale and rank hierarchy cultures and especially introduce development culture which should be established within the military organization.

Objectives: This study investigates whether the reverse interpretation of low Pa score in MMPI that indicate a paranoid tendency is appropriate. Methods: The 96 psychiatric patients perform MMPI and Rorschach test, and their clinical diagnosis and symptoms were evaluated. Study group is divided into high, middle and low Pa group on the basis of Pa score. Dependent variables were Rorschach Hypervigilance Index(HVI), content index related to the paranoid tendency, clinician`s diagnosis and symptoms, MMPI validation scale, and Harris-Lingoes subscale. If the reverse interpretation were valid, low Pa group would differ from middle Pa group in dependent variables and not from high Pa group. Results: HVI cannot discriminate the three group. On the other hand, in the analysis of MMPI validation scale and Harris-Lingoes subscale, the low pa group had higher score on L, K scale than high Pa group. Low Pa group is significantly high in Naivete(Pa3) but low in Persecutory idea(Pa1) and Poignancy(Pa2). That is, patients with low Pa scores were more defensive about their own problems or symptoms and revealed less persecutory idea. But they leaked their covert paranoid tendency through the Naivete subscale. Conclusion: Low score on Pa does indicate paranoid tendency.

Characteristics of a Modified regenerative cycle gas turbine has been investigated. In the cycle, the turbine expansion is divided into two parts and the regenerator locates between them. Two types of mechanical design are assumed : two-shaft and single-shaft. In particular, optimal pressure ratio division between the high and low pressure turbines is evaluated for the single shaft configuration. The part load analyses have been carried out with the aid of off-design models. In addition to the general fuel only control, a variable speed control is assumed as the part load operating strategy of the single shaft configuration. Obvious advantage with the alternative cycle is observed in the variable speed operation of the single shaft design.
RBS-B 접합부를 가진 철골 모멘트골조의 내진성능 평가

Reduced Beam Section connections (RBS) are newly developed connections for steel moment frames. FEMA 350 permits the RES with a bolted web connection (RES-B) to be used in Special Mement Frames (SMF). However, there is experimental data showing at least some RES-B connection test specimens that failed to achieve the rotations required of SMF connections. In ANSI/AISC 358 which represents essentially an updated version of FEMA 350, the RBS-B connection is not prequalified for use in SMF connection. Only the RBS with a welded web connection (RBS-W) is prequalified for SMF The objective of this study is to evaluate the seismic performance of the steel moment frames with RBS-B. For this purpose, 3-story, 9-story, and 20-story steel moment frame buildings located in Los Angles were considered. Nonlinear static pushover analysis, nonlinear time history analysis (NLTH), and incremental dynamic analysis (IDA) are conducted. According to FEMA 350, confidence level of the frame was evaluated for the two performance objectives, IO and CP against the hazard level of 50% and 2% in 50 years. The seismic performance was evaluated in compliance with procedure specified in FEMA 350.

The objective of this study is to evaluate the seismic performance of Welded Unreinforced Flange-Welded web (WUF-W) moment connections designed according to requirements of the current seismic codes. The effects of beam depth and panel zone strength on plastic rotation capacity of WUF-W moment connections were described in these tests. In total, four full-scale one-sided test specimens were considered and quasi-static cyclic testing was conducted. From the test results, it was found that test specimens having deep beam fractured in the beam flange before achieving total interstory drift angle of 0.04 radian required for Special Moment Frames (SMF) system in ANSI/AISC-341, while shallow beam specimens performed well, achieving total interstory drift angle of at least 0.04 radians. Also, WUF-W moment connections fabricated using access hole details specified in the provision are prone to premature fracture in the beam flange before satisfying the requirement of beam-to-column connections used in SMF system due to the increase of the strain demand at the toe of the beam flange..
