This study confirmed the effects of leaders' behavioral integrity on organizational members' voice behavior. It verified whether trust in leaders mediates behavioral integrity and voice behavior and ascertained the moderating effect of members' psychological safety on trust in leaders and members' voice behavior through leaders' behavioral integrity. It targeted organizational members in the service industry, including insurance, securities, banks, consulting, and credit card companies, with a questionnaire survey carried out with 424 response copies. The study results confirmed a significant and positive effect of leaders' behavioral integrity on trust in leaders and voice behaviors. Second, trust in leaders was found to mediate between leaders' behavioral integrity and members' voice behavior. Third, members' psychological safety had a moderating effect on trust in leaders and members' voice behavior. When psychological safety was higher than average, there was a moderated mediating effect of psychological safety in the behavioral integrity on voice behavior with trust mediation in leaders. Therefore, this study has significance in that it was determined that trust in leaders and the psychological safety of the members are essential for leaders' behavioral integrity to enhance members' voice behavior.

Purpose: The study was done to compare effects of two endotracheal tube (ET tube) fixation methods (rotated fixation versus conventional) on unplanned extubation and skin integrity for orally intubated patients in intensive care units. Methods: The research design was a non-equivalent control group with repeated measures design. Participants were 80 patients; 40 participants assigned to each group. ET tube for the experimental participants fixed with rotated method every morning. Unplanned extubation was assessed by bedside nurses using the unplanned extubation report form. Oral mucosa and facial skin integrity were assessed using oral assessment guide and facial skin integrity assessment guide at day 3, 7, 10 and 14. Results: There was no difference in the unplanned extubation rate between the two groups. Oral mucosa impairment scores for the rotated fixation method were significantly lower at day 7 (p=.044), 10 (p=.048) and day 14 (p=.037). Also facial skin integrity impairment scores for the same group were significantly lower at day 7 (p=.010), 10 (p=.003), and 14 (p=.002). Conclusion: Results of the study suggest that the rotated fixation method is effective for these patients, to prevent impairment of oral mucosa and facial skin integrity. Further research is needed to prevent unplanned extubation.

As digital evidence has a highly influential role in proving the innocence of suspects, methods for integrity verification of such digital evidence have become essential in the digital forensic field. Most surveillance camera systems are not equipped with proper built-in integrity protection functions. Because digital forgery techniques are becoming increasingly sophisticated, manually determining whether digital content has been falsified is becoming extremely difficult for investigators. Hence, systematic approaches to forensic integrity verification are essential for ascertaining truth or falsehood. We propose an integrity determination method that utilizes the structure of the video content in a Video Event Data Recorder (VEDR). The proposed method identifies the difference in frame index fields between a forged file and an original file. Experiments conducted using real VEDRs in the market and video files forged by a video editing tool demonstrate that the proposed integrity verification scheme can detect broken integrity in video content.

The objective of this paper is to develop an expert system for nuclear piping integrity. This paper describes the selection methodology of integrity evalution method and the inference of material properties. To select the integrity evaluation method, the weight factor for respective material properties was obtained by the sensitivity analysis of the effect of material properties on integrity evaluation method. Subsequently the possession ratio for respective integrity evaluation method was computed, and the most appropriate integrity evaluation method for given input information is selected. In the material properties inference, stress-strain curves and J-R curves were predicted from tensile properties such as yield strength and tensile strength.

The estimation of fatigue integrity is very important for aerospace structures such as engine mount strut. The reason is that the fatigue integrity is essential analysis process to establish the structural stability in aerospace field. Therefore, in this paper, the process of fatigue analysis and test was performed for engine mount strut to prove the structural fatigue integrity. First of all, the fatigue load spectrum is constructed by considering the small aircraft operating condition. Fatigue analysis is done for the cluster near the welding zone which may have F.C.L.(fracture critical location). The fatigue life of engine mount strut was estimated by the Miner's rule which is the damage summation method. Finally, Fatigue test is performed to verify the fatigue integrity. The estimation process of fatigue integrity for engine mount strut of small aircraft may help the design.

An educational program through therapeutic recreation was developed in order to analyze the effect of enhancement of ego integrity of the elderly. First of all, this study was designed to summarize the concepts of ego integrity and the effects of therapeutic recreation on the elderly and to identify elderly's educational needs of both educational methods and contents from the literature review. The above identified knowledge and information were applied to developing the educational program. The program was composed of 6 sessions with 17 old men and women focused on developing self acceptance using reminiscence on ego integrity through their whole life span and developing positive and active attitudes towards life. And enforcing and evaluation methods were also suggested. The results were as follows. This program showed the significant differences between post-test and pre-test scores in the scale of ego integrity of the elderly. In conclusion, educational program through therapeutic recreation employed for this study has significant effects of increasing ego integrity of the elderly.

The objective of this study was to test the effects of participating self-growth program on ego-integrity and family relationship satisfaction of the elderly women. The subjects were 15 elderly women of low education. The levels of ego-integrity, including life attitudes, wisdom toward life, acceptance of life, and acceptance of death, and family relation satisfaction were measured before and after completing the program sessions. The program of eight sessions was conducted twice a week, for two hours. A significant difference in ego integrity, relation satisfaction with children, and relation satisfaction with grandchildren was found between pre- and post-test scores. The results show that elderly women can benefit from programs enhancing ego integrity and relation satisfaction with offspring. This study can be utilized in the Healthy Family Support Centers or the elderly welfare program for improvement of ego-integrity and parent-child relationship satisfaction of the elderly.

This paper introduces a new computational efficient Dilution of Precision (DOP)-based landmark exclusion method while ensuring the safety of the LiDAR-based navigation system that uses an innovation-based Nearest-Neighbor (NN) Data Association (DA) process. The NN DA process finds a correct landmark association hypothesis among all potential landmark permutations using Kalman filter innovation vectors. This makes the computational load increases exponentially as the number of landmarks increases. In this paper, we thus exclude landmarks by introducing DOP that quantifies the geometric distribution of landmarks as a way to minimize the loss of integrity performance that can occur by reducing landmarks. The number of landmarks to be excluded is set as the maximum number that can satisfy the integrity risk requirement. For the verification of the method, we developed a simulator that can analyze integrity risk according to the landmark number and its geometric distribution. Based on the simulation, we analyzed the relationship between DOP and integrity risk of the DA process by excluding each landmark. The results showed a tendency to minimize the loss of integrity performance when excluding landmarks with poor DOP. The developed method opens the possibility of assuring the safety risk of the Lidar-based navigation system in real-time applications by reducing a substantial amount of computational load.

Purpose: This study was conducted in order to determine the extent of ego integrity and to confirm the association between the sense of ego integrity and integrated loneliness, social support, and social activities. Methods: For this study, 146 elderly people participated. The data was analyzed with SPSS/WIN 21.0, using descriptive statistics, t-test, ANOVA, correlation analysis, and hierarchical regression analysis. Results: In regards to differences between ego integrity according to general characteristics of subjects, there was a statistically significant difference in education (F=4.13, p=.007). In elderly living alone, ego integrity was significantly positive correlated with social support and social activities, but negative correlated with loneliness. These variables explained 43.2% of the sense of ego integrity. Conclusion: The study suggested that nursing programs and social activity programs designed to aid the elderly living alone must focus on reducing loneliness, as well as increasing social support and social activities, while taking education into consideration. Also, these programs should strive to build social support systems.

In order to manage nuclear power plants safely and cost effectively, it is necessary to develop integrity evaluation methodologies for the main components. Recently, the integrity evaluation techniques were broadly studied regarding the license renewal of nuclear power plants which were approaching their design lives. Since the integrity evaluation process requires special knowledges and complicated calculation procedures, it has been allowed only to experts in the specified area. In this paper, an integrity evaluation system for reactor pressure vessel was developed. RVIES(Reactor Vessel Integrity Evaluation System) provides four specific integrity evaluation procedures covering PTS(Pressurized Thermal Shock) analysis, P-T(Pressure-Temperature) limit curve generation, USE(Upper Shelf Energy) analysis and Fatigue analysis. Each module was verified by comparing with published results.
