A vacation destination was conceptualized to be chosen through a three-stage process consisting of an early consideration set formation, a late consideration set formation, and a final selection stage. Choice criteria were defined as an individual's belief toward the relationships between perceived attributes, expected outcomes, and the destination. And these criteria were assumed to be divided into benefit-related dimension and perceived risk-related dimension. Through two pilot surveys, 13 items which have 4 factors were identified. used on 4 factor structures, the benefit-related dimension was identified to be consisted of three sub-dimensions, "historic/cultural", "escaped" and "naturalness". A longitudinal panel survey was used to test the differences of the importance of choice dimensions through the choice process. The importance of benefit-related dimension was decreased through the choice process as hypothesized except "naturalness" factor. And as hypothesized, the importance of perceived risk-related dimension was increased.

Subsequent to major changes in workplace such as communication method, uncertain organizational environment, and globalizaiton, several studies in workplace have explored the effects of those changes on work outcomes. Especially, employees need to have the balance in working alone and working with others. The purpose of this study is to examine the effects of control over the physical environment by individuals and the effects of flexibility on individual and group work outcomes in the workplace, to examine the effects of distraction on work outcomes, and to suggest a interrelationships among variables. In this study, four hundred and nine questionnaires were collected from employees of three manufacturing corporations in Michigan, U. S. In order to explore the causal interferences among multiple relationships suggested in this study, path analysis was employed using Lisrel 8.54. The results indicated that control over the physical environmental features of the workplace positively influenced job satisfaction. The findings also supported the hypothesis that flexibility is positively related to task group cohesiveness. It was found that distraction was negatively associated with control and flexibility. However, it was not supported that control was positively associated with perceived performance. This study found control and flexibility in the workplace to be important. Some practical implications were suggested emphasizing that control and flexibility allow limited resources to be used in ways that permit individuals to work effectively within a changing work environment.

This study examined the antecedents and outcomes of leader-member exchange (LMX) quality in the Korean Army platoons. Although a number of studies have devoted substantial attention to the application of the LMX theory in various organizational settings, there has been no effort to verify or to apply the model to a military situation. In this paper, we tried to build an integrative LMX model to apply to the Korean army. We developed, on the basis of literature review, an integrative framework describing the factors affecting the LMX quality, LMX quality outcomes and the moderators of LMX quality-outcomes. Then we collected data from the 404 lieutenant-soldier dyads. The analysis of the data showed that 1) interpersonal variables (perceived similarity and liking of soldier) and LMX quality were significantly related, 2) LMX quality and outcome variables(soldier's performance, job satisfaction, and morale) were significantly related, and 3) the relationship between LMX quality and soldier's performance were strongly significant when task challenge is high but nonsignificant when task challenge is low, while there were nonsignificant or weekly significant relationships between LMX quality and soldier's performance when task challenge is moderate. The results are basically coinciding with the previous research, except that, with the low challenge tasks, the LMX quality did not affect soldier's performance, which seems to be due to the directive leadership style of the lieutenants. The theoretical and practical implications and future research directions are discussed.

Purpose: Coronally advanced split-or full-thickness (CAST or CAFT) flaps in combination with subepithelial connective tissue grafts (SCTGs) are commonly used in root-coverage procedures despite postoperative pain and bleeding from the graft donor site. Therefore, the modified vestibular incision subperiosteal tunnel access procedure (VISTAX) uses a novel collagen matrix (VCMX) instead of autogenous tissue to address the limitations associated with autogenous tissue grafting. This retrospective study compared the clinical outcomes of VISTAX to the results obtained after using a CAST or CAFT flap in combination with SCTG for root coverage. Methods: Patients with single or multiple adjacent recession I/II defects were included, with 10 subjects each in the VISTAX, CAFT, and CAST groups. Defect coverage, keratinized tissue width, esthetic scores, and patients' perceived pain and dentinal hypersensitivity (visual analogue scale [VAS]) were assessed at baseline, 3 months, and 6 months. Results: All surgical techniques significantly reduced gingival recession (P<0.0001). Defect coverage, esthetic appearance, and the reduction in dentinal hypersensitivity were comparable. However, the VAS scores for pain were significantly lower in the VISTAX group than in the CAFT and CAST groups, which had similar scores (P<0.05). Furthermore, the clinical results of VISTAX and CAFT/CAST generally remained stable at 6 months. Conclusions: The clinical outcomes of VISTAX, CAFT, and CAST were comparable. However, patients perceived significantly less pain after VISTAX, indicating a potentially higher patient acceptance of the procedure. A prospective trial with a longer follow-up period and a larger sample size should therefore evaluate VISTAX further.

The purpose of this study was to identify the differences of the outcomes of visiting nursing service (VNS) between the two types by the organizational structure of health centers. Type I referred to 3 health centers with departmentalization for VNS and type II of 3 health centers providing VNS under the subunit of a department. Data were collected from 38 visiting nurses at the six health centers for their perceived formalization, decision-making authority and job satisfaction, 293 clients for the satisfaction level with VNS served and their records analysis for level of quality care and frequency by the contents of VNS through the questionares during the period from June, 1 to August 30, 1993. Data were analyzed using $\chi^2$, F. t or/and Scheffe test. The result were as follows: 1) There were no significant differences in perceived formalization and decision -making authority of visiting nurses between the two types of health centers. 2) There were significant differences in the level of quality care and frequency of the VNS contents between the two types of health centers. 3) There were no significant differences in perceived clients' satisfaction and job satisfaction of the visting nurses between the two types of health centers. From this study, Not only organizational differentiation with the development of job standards and supportive system but also personnel development are suggested when new health care service in health centers begins.

Purpose: The purpose of this study was to examine the effects of physical, psychological, and social factors on the health status of patients undergoing hemodialysis using longitudinal data. Methods: Two surveys were conducted within a period of two-year. A total of 75 patients participated in both surveys. Eight variables including symptoms, treatment belief, hope, meaning-focused coping, family support, friend/peer support, healthcare provider support, and health status were measured. Data were analyzed by paired t-test, Pearson's correlation coefficients, and hierarchical multiple regressions. Results: The mean age of the participants was 47.31 and the average duration of dialysis was 8.27 years. There was no difference in scores on perceived health status between the two year-interval surveys. The two-year follow-up on perceived health status was correlated with baseline perceived health status, friend/peer support, meaning-focused coping, hope, and symptoms. As the result of the regression analysis, friends/peer support (${\beta}=.31$, p=.013) and baseline perceived health status (${\beta}=.30$, p=.020) were found to be significant predictors of subsequent health status which explained 39.0% of the variance. Conclusion: This study suggests the importance of psychosocial resources for positive health outcomes in patients with a chronic illness. Nursing interventions aimed to provide renal peer support need to be developed and tested.

In recent years, large-scale and high-density use of LED on facades has exposed some disadvantages, such as light pollution, high energy consumption, unsustainability, and poor interactivity. Because of the development of smartphones and augmented reality (AR), AR has emerged as a new technology available to users to interact with the media façade. As an augmented reality app for public space, the AR map app can superimpose virtual images on the surface of a building to form an AR media façade, which can be applied in the fields of navigation, advertising, interactive public art, smart retail, etc. This study establishes the variables influencing usage intention and the consequent outcomes of Huawei AR map app and uses the technology acceptance model (TAM) to discuss their relationship. Results show that consumer innovativeness, information quality, and design quality have a strong influence on perceived ease of use. Information quality has a positive impact on perceived usefulness, but design quality has a weak influence. Also, the design quality of Huawei AR map app and consumer innovativeness have a higher effect on perceived enjoyment than information quality. Users' usage attitude and perceived usefulness when using Huawei AR map app are key factors determining their usage intention. This study inspires city planners, architects, developers, and designers of AR apps that augmented reality can partly replace media façade, and that investment in augmented reality will achieve significant sustainable economic and social benefits.

The present study examined the causal relationships among nurses' perceived autonomy, job satisfaction, work environment (work overload, role conflict, situational support, head nurses' leadership), personal aspects(experiences, need for achievement, professional knowledge and skill) by constructing and testing a theoretical framework. Based on literature review nurses' perceived autonomy and job satisfaction were conceived of as outcomes of the interplay among work environment and personal characteristics. Work environment factors involved work overload, role conflict, situational support, and head nurses' leadership (task oriented leadership, relation oriented leadership). Personal charateristics included experiences, need for achievement, and professional knowledge and skill. Three large general hospital in Chonbuk were selected to participate. The total sample of 516 registered nurses represents a response rate of 92 percent. Data for this study was collected from July to September in 1998 by Questionnaire. Path analyses with LISREL 7.16 program were used to test the fit of the proposed conceptual model to the data and to examine the causal relationship among variables. The result showed that both the proposed model and the modified model fit the data excellently. It needs to be notified, however, that path analisis can not count measurement errors; measurement error can attenuate estimates of coefficient and explanatory power. Nevertheless the model revealed relatively high explanatory power. 42 percent of nurses' perceived autonomy was explained by predicted variables; 32 percent of nurses' job satisfaction was explained by by predicted variables. Tn predicting nurses' perceived autonomy the findings of this study clearly demonstrated the work overload might be the most important variable of all the antecedent variables. Head nurses' relation oriented leadership, situational supports, need for achievement, and role conflict were also found to be important determinants for nurses' perceived autonomy. As for the job satisfaction, role conflict, situational supports, need for the achievement, and head nurses' relation oriented leadership were in turn important predictors. Unexpectedly the result showed perceived autonomy have few influence on job satisfaction. The results were discussed, including directions for the future research and practical implication drawn from the research were suggested.

Purpose: This study aimed to examine the levels of perceived self-management support, self-efficacy for self-management, and health-related quality of life (HRQoL) in cancer survivors, and to identify the mediating effect of self-efficacy in the relationship between perceived self-management support and HRQoL. Methods: This study used a descriptive correlational design. Two hundred and four cancer survivors who had completed treatment participated in the study. Measurements included the Patient Assessment of Chronic Illness Care Scale, the Korean version of the Cancer Survivors' Self-Efficacy Scale, and the Medical Outcomes Study Short Form-36. Data were analyzed using descriptive statistics, Pearson's correlation coefficient analysis, and multiple regression analysis using Baron and Kenny's method for mediation. Results: The mean score for perceived self-management support was 3.35 out of 5 points, self-efficacy was 7.26 out of 10 points, and HRQoL was 65.90 out of 100 points. Perceived self-management support was significantly positively correlated with self-efficacy (r=.29, p<.001) and HRQoL (r=.27, p<.001). Self-efficacy was also significantly correlated with HRQoL (r=.59, p<.001). Furthermore, self-efficacy (${\beta}=.55$, p<.001) had a complete mediating effect on the relationship between perceived self-management support and HRQoL (Z=3.88, p<.001). Conclusion: The impact of perceived self-management support on HRQoL in cancer survivors was mediated by self-efficacy for self-management. This suggests that strategies for enhancing self-efficacy in cancer survivors should be considered when developing self-management interventions for improving their HRQoL.

This study aims at developing and empirically testing a comprehensive model of organizational justice derived from the prior empirical studies on organizational justice. The study seeks to understand the antecedents to and the consequences are addressed. The first question is what characteristics of the HRM systems determine the levels of perceived distributive and procedural justice. Hypotheses are derived from the two prominent theoretical models, i.e., the self-interests model (SIM) and the group value model (GVM). Those factors include neutrality, consistency, accuracy. ethicality. credibility. and reciprocity in the processes of making HRM decisions. All nine factors suggested by the two models aye adopted for this study as major determinants of both distributive and procedural justice. The second question of this study is related to the moderating effects of individual differences on the relationship between the SIM and GVM variables and perceived distributive and procedural justice in organizational contexts. The final research question deals with the consequences of perceived organizational justice. specifically job - related altitudes and organizational commitment. Job-related attitudes in this study refer to job satisfaction, job motivation, and job involvement, i.e., the willingness to make contributions. identification with organization, and intent to stay. In examining the consequences of perceived organizational justice, the study focuses on the interaction effects of procedural and distributive justice on the above nine outcome variables. The results show that both SIM and GVM variables significantly influence distributive and procedural justice. However, hierarchical regression analyses reveal that the GVM variables except more influence has been focused on the consequences of perceived distributive justice with regard to outcomes provided by the organization.
