Joint transform correlator (JTC) has been the most suitable technique for real time pattern recognition. This paper proposes a new phase adjustment which adopts two steps of random phase adjustment in the spatial domain and additional phase adjustment in the Fourier domain. Simulated results are presented to show the optimum condition of the phase adjustment and the effect on the correlation peaks, the peak signal-to-noise ratio and the level of discrimination.

Purpose: The purpose of this study was to understand the adjustment process of middle-aged people in Korea with hemiplegia after a stroke. Method: For this study, the grounded theory method was utilized. Results: After constant comparative analysis, the core category emerged as 'rebuilding the body which was ruined'. In addition, the causal conditions were 'restriction of physical function', and 'loss of roles'. The adjustment process consisted of the 'facing reality phase', 'overcoming depression phase', 'overcoming physical limits phase' and 'reestablishing roles phase' The main strategies in the facing reality phase were 'holding on to a glimmer of hope', 'getting away from the harsh reality' and 'facing up to the reality'. The main strategies in the overcoming depression phase were 'soothing oneself', 'Self-introspection' and 'restoring self-esteem'. In addition, the main strategies in the self-initiative overcoming physical limits phase was 'discovering personal strategies and striving to recover'. The main strategies in the reestablishing roles phase were 'reestablishing a parents' role', 'reestablishing a spouse's role' and 'reestablishing social roles'. Conclusion: In conclusion, even though many middle aged stroke patients remained in the depression phase, most of them who overcame depression strived to conquer physical limits on their own initiative.

The number of residents in elderly institution has been increasing due to the change of the family support system. This study was focused on understanding the process of adjustment of the institutionalized elderly using the Grounded Theory approach. Method: There were seven participants, 4 men and 3 women living in 3 different elderly facilities. The data was collected through in-depth interviews and participant observation from June 20, 1999 to January 10, 2000 and analyzed by the Strauss and Corbin's analysis method. Result: 125 concepts were found and grouped into 30 sub-categories and then grouped into 13 categories. These categories are , , , , , , , , , , , and , which were synthesized into the process of adjustment. being the core category. The adjustment process of the facility elderly consisted of : 1. expressive phase of 'reluctance' 2. control phase of 'reluctance' 3. latent phase of 'reluctance' Conclusion: This study offers better understandings on the adjustment process of the institutionalized elderly and provides more appropriate nursing care to the New Comers of these facilities.

In this study, we have analyzed the cost of korea high-speed railway system. The predicted cost in planning phase and adjustment data to 5th year are collected. Then, predicted cost is compared with adjustment in year/item/system base. We make a project history table for criteria to review project history and research & development activity. We have developed CBS(cost breakdown structure) and allocated adjustment data to them. It is shown that cost prediction related to research & development activity in planning phase is relatively correct.

Two-dimensional(2-D) radar images, namely, ISAR images from a maneuvering target include unwanted phase errors due to the target's motion. These phase errors make ISAR images to be blurred. The ISAR autofocus technique is required in order to remove these unwanted phase errors. Unless those unwanted phase errors produced by the target's motion are removed prior to target identification, we cannot expect a reliable target identification performance. In this paper, we use the entropy-based ISAR autofocus technique which consists of two steps: range alignment and phase adjustment. We analyze a relationship between the number of sampling point and a image quality in a range alignment algorithm and also analyze a technique for reducing computation time of the SSA(Stage-by-Stage Approachng) algorithm in a phase adjustment.

This paper investigates optimum air-gap flux distribution with third harmonic rotor flux orientation adjustment for five-phase induction motor. The technique of objective is to generate a nearly rectangular air-gap flux, and it improves iron utilization under variation loading conditions. The proportional relations between third harmonic and fundamental plane currents is usually adopted in the conventional method. However, misalignment between fundamental and third harmonic component occurs with variation loading. The iron of stator teeth is saturated due to this misalignment. This problem is solved by third harmonic rotor flux orientation adjustment simultaneously, and direction and amplitude are changed with mechanical load variation. The proposed method ensures that the air-gap flux density is near rectangular for a maximum value from no load to rated load. It is confirmed that the proposed method guarantees complete both planes decoupling with third harmonic flux orientation adjustment. The effectiveness of the proposed technique is validated experimentally.

Purpose: The purpose of this research was to describe the decision making experience of VIP ward nurses in the clinical practice adjustment process. The research question was about "how nurses adjust their clinical practice to nursing situations and develop decision making process in a VIP ward." Method: The methodology of collecting and analyzing the data was based on the grounded theory of Strauss and Corbin(1998). The data was collected through in-depth interviews with 10 nurses from July to November, 2007. Results: The core category of nursing care decision making process was named as "adjusting with flexibility and deepened insight." The clinical practice adjustment process in nursing care decision making has progressed through four preceding interlocking phases: 1) dependent phase, 2) defensive phase, 3) independent phase, 4) integrative phase. These phases were classified by the level of nurses' dependency, proactivity, presupposition and integration. Conclusion: The result of this study indicated that nurse's decision making depended on their experiences and the nature of social context in which nursing occurs. Therefore, it is important to elaborate an effective training program for nurses to develop the phases of nursing care decision making.

Purpose: This study aimed to identify the attributes of social adjustment among adolescent cancer survivors using concept analysis and to propose a definition of the concept. Methods: In accordance with the hybrid model of concept analysis, this study employed a three-phase circular process comprising theoretical, fieldwork, and final analysis phases. A thorough literature review was conducted using MEDLINE, Embase, and Korean databases, followed by qualitative fieldwork with seven participants. The results derived from the theoretical and fieldwork phases were integrated into the final analysis phase. Results: Four attributes of social adjustment were found in adolescent cancer survivors: having harmonious relationships with friends, having harmonious relationships with boy/girlfriends, fulfilling their present roles, and planning for and expecting future roles. The following definition of social adjustment of adolescent cancer survivors is proposed: "the conquering of difficulties arising from the continuum of childhood cancer and the achievement of the developmental tasks of typical adolescents." Conclusion: Social adjustment of childhood cancer survivors is crucial for integrating them into society. The findings of this study provide a basis for developing an instrument to measure the social adjustment of adolescent cancer survivors and for developing of interventions that target this group.

Structural vibrations of adjacent buildings, manufacturing factories and engines on the stationary diesel power plant were increased by the variation of phase angle between two engines sometimes. In this paper, top bracings and synchrophaser have been introduced in order to reduce these vibrations. As a result, all of structural vibrations were greatly improved by the phase adjustment of 6th order X-mode vibration with these.
