Purpose: Objectives of this study was to investigate the level of anxiety and depression according to the stages of autologous and allogeneic hematopoietic stem cell transplantation (HSCT). It would be provide the basis for effective psycho-emotional nursing intervention. Methods: We report on 52 patients, including 19 with autologous HSCT, and 33 with allogeneic HSCT from August 2002 to August 2003, at a university hospital. Spielberger's State-Trait Anxiety Inventory and Jung's Depression Inventory were used to measure levels of anxiety and depression, respectively, at admission time, the day before HSCT, and discharge time. Data was analyzed using SAS program that included Chi-square test, Fisher's exact test, repeated measures ANOVA and Stepwise multiple regression analysis. Results: In all stages of HSCT, the level of anxiety of patients who underwent allogeneic HSCT was significantly higher than that of autologous HSCT (P=0.047). The depression at the day before HSCT was significantly higher than that at admission. The major variable affecting anxiety in autologous HSCT was depression. Specially depression and gender were significant predictors to explain anxiety in allogeneic HSCT at admission time (61%). Experience of relapse and gender were significant predictors to explain anxiety in allogeneic HSCT at discharge time (36%). Conclusion: We recommend that the anxiety and depression be researched during the stages of allogeneic HSCT, specifically in the day before HSCT. It is necessary to develop an effective psycho-emotional nursing intervention according to the stages of HSCT.

Statistics of aviation accident in Korea show that safety level of training flights is high. However, more than 80% of aviation accidents happen owing to human factors. And because most reasons of them are concerned with pilot error, it is very important for student pilots who will transport a lot of passengers to develop the knowledge of safety and abilities of risk management for preventing accidents. In this study, in order to investigate the Human Factors which affect safety in training student pilots for flight, verified the correlationbetween experiences of accident, the differences according to the experience level of training flight and the differences between college student pilots and ordinary student pilots on the basis of human factors that composes the SHELL models. For the study, Using SPSS 17.0, conducted Correlation Analysis, Analysis of Variance(ANOVA) and t-test. To sum up the result of this study, student pilot's ability and equipment in the cockpit are the important factors for safety when pilots are training flight. Also the analysis of the differences between human factors according to the characters of student pilots' groups shows that college student pilots are affected by immanent factors and organizational cultures. So far, there haven't been any accidents which is related with human casualties when training at the ATO(Approved Training Organization). But accidents can occur at any time and anywhere. Especially the human factors which comprises most of aviation accident have a wide reach and are impossible to be eliminated, therefore, it is best to minimize them. Because ATO is the starting point to lead the aviation industry of Korea, we will have to be aware of problems and improve education/training of human factors.

Objective : This study aimed to examine the association between the structural and functional aspects of social networks and health-promoting behaviors in community-dwelling older adults. Methods : Social networks based on structural and functional aspects and health-promoting behaviors by lifestyle were measured in 226 community-dwelling adults aged 65 years and over. To analyze the collected data, an independent t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical regression were performed. Results : The network size was the highest in the friend network, and the frequency of contact and social support was the highest in the non-living family network. Health-promoting behaviors were highest for activities of daily living and lowest for productive and social activities. All subfactors of social networks showed significant positive correlations with health-promoting behaviors. Hierarchical regression showed social support from neighbors as the variable with a significant effect on health-promoting behaviors; gender and depression were also influencing factors, and this model showed 37% explanatory power. Conclusion : To promote healthy behaviors of older adultsin the community, the development of health promotion programs and related policies considering social networks centering on social support from neighbors is required.

This study was conducted to minimize the imaging distortion by reducing the differences in susceptibility between the tissue and air surrounding it while performing a thyroid diffusion imaging procedure. The study group was composed of 23 healthy adults. Thyroids with many distortions near the air, larynx, and trachea were chosen to test and evaluate the diffusion imaging difference between before and after an application of silicon. As a result, there was reduced distortion with silicon application, and the differences decreased from 30% to 10%. According to One-way ANOVA and Duncan's post-hoc test, there were no significant differences between imaging with a silicon application and T2 imaging of the surface area, which was the standard image. In conclusion, this study presented a radical improvement in reducing the distortions in imaging by compensating for an uneven tissue surface near air without affecting the magnetic resonance contrast and complicating the imaging processes.

Objective : The purpose of this study was to investigate the necessity of occupational therapist's involvement in patient discharge planning, the areas that should be considered for discharge screening and planning, and to provide the basic data required for the development of a discharge assessment tool. Methods : We conducted an online questionnaire survey of 60 occupational therapists who were working at medical institutions and had agreed to participate in the study. The questionnaire was composed of 36 questions regarding the general characteristics of the current discharge planning process and the necessity of discharge assessment and planning. Descriptive statistics, an independent t-test, and a one-way ANOVA were conducted using SPSS 20.0. As for the post-hoc test, Scheffe's test was used. Results : The awareness of occupational therapist's role in discharge planning and the necessity of a discharge assessment tool were high, but the occupational therapist's awareness of discharge-related knowledge was low. The difficulties in discharge planning showed high response rate in the absence of adequate fee-for-service in the patient interview and assessment and the lack of team approach and appropriate assessment tools for discharge planning. The high-needs areas for evaluation during discharge were fall risk and BADL, and the low-needs areas were well-being and functional level prior to onset. Conclusion : This study is expected to provide preliminary information necessary for the development of a discharge assessment tool for effective discharge planning.

The purpose of this study was to determine whether association exists between temporomandibular joint (TMJ) characteristics in transcranial radiographs and TMJ internal derangement and to evaluate the validity of transcranial radiographs in diagnosis of internal derangement. Transcranial radiographs and magnetic resonance imaging (MRI) of 113 TMJs from 76 subjects were used for this study and all TMJs were classified into 3 groups according to the results of MRI: normal disk position, disk displacement with reduction, and disk displacement without reduction. Transcranial analysis included linear measurement of joint spaces and condylar head angle measurement. To determine any relationship between transcranial measurements according to disk displacement, one-way ANOVA was used. The results showed that condyle-fossa relationship in standard transcranial radiographs had no relationships with disk displacement. And, as disk displacement progressed, condylar angle between head and neck increased significantly. This result can be interpreted that condylar head angle reflects structural hard tissue change according to internal derangement progress. But this is insufficient in the determination of internal derangement. Therefore, although still clinically helpful, the validity of standard transcranial radiographs to diagnose TMJ internal derangement was questioned.
