Contemper nursing literature place much importance on human- centered and individualized care. Nursing research has related stress during hospitalization of adolescent patients to adaptation to a new environment, isolation from friends, limitation due to illness, over protection of parents and communication with member of the medical team. The investigator conducted this study in the hope that an understanding of adolescents responses to hospitalization, their perceptions, the kinds and levels of stress, and the relationships between stressors and individual characteristics would contribute to the improvement of adolescent patient care. The objective of the study was to obtain informations related to the adolescents psychological stress experience during hospitalization, specifically stress from interpersonal relationships and communication, isolation from the family, social or economic problems, illness and from the treatment environment and nursing care. An interview schedule adopted from Holmes and Rahe's Social Readjustment Rating Scale and selected items from Voicer's instrument on stress-producing events was used with 120 adolescent inpatients aged 13 to 18 years three general hospitals in Seoul during Aug. 10, to Sep. 30, 1975. 1. The sample consisted of 66 male and 54 female patients. Sixty-six percent were late adolescents, aged 16 to 18 years: 4% were early adolescents, aged 13 to 15 years. The primary cause for hospitalization was for orthopedic problems (35.8%). More than half of these (54.4%) were due to injury or accident. 2. Stress eclated to illness revealed the highest score (4.97), followed by stress related to treatment environment and nursing care (4.34) , isolation from family and social or economic problems (4.01) and interpersonal relationships and communication (3.96). 3. The perceived indifference of doctors and nurses was a serious cause of stress (mean=4.83). Fellow patients and visitors caused least stress (mean=2.06). 4. Discontinuation of education or unemployment were major stressful events (mean=4.71). Least stressful was isolation from the family (mean=3.47). 5. More than 94% of the respondents expressed fears related to body image (mean=4.97) 6. Within the category of treatment environment and nursing care, items related to restrictions because of treatment, discomfort because of treatment, inadequate explanation from nurses about procedures were rated as severe stress events (mean=4.6). Items related to the ward environment and to having a relative stay with them were seen by the group as less serious events (mean=3.7). 7. Stress related to interpersonal relationships and communication was correlated positively with female patients and those preferring passive activities. (P〈0.05) 8. Stress related to family problems was positively related to female and early adolescent patients (P< 0.05). Stress related to social problems was positively , elated to students and those preferring active pursuits (P< 0.05). 9. There were no correlation between the high stress related to disease and any of the characteristic items. (P> 0.05) 10. Stress related to treatment environment and nursing care was positively related of early adolescent and female and student patients. (P< 0.05) This group of hospitalized adolescents reported high level of stress related to treatment environment and nursing care, due to lack of consideration of normal growth and development and individual characteristics. The findings have important implications for the planning of effective, individualized, comprehensive nursing care of adolescents during hospitalization.

Positron Emission Tomography(PET) is a new diagnostic method that can create functional images of the distribution of positron emitting radionuclides, which when administered intravenously in the body, makes possible anatomical and functional analysis by quantity of biochemical and physiological process. After genetic and biochemical changes in initial stage, malignant tumor undergoes functional changes before undergoing anatomical changes. So, early diagnosis of malignant tumors by functional analysis with PET can be achieved, replacing traditional anatomical analysis, such as computed tomography(CT) and magnetic resonance image(MRI), etc. Similarly, PET can identify malignant tumor without confusion with scar and fibrosis in follow up check. In the Korea Cancer Center Hospital(KCCH) from October 1997 to September 1999, clinical study was performed in 79 cases that underwent 89 times PET evaluation with [18F]-Fluorodeoxyglucose for diagnosis of oral and maxillofacial tumors, and the data was analysed by Bayesian $2{\times}2$ Classification Table. The results were as follows : Evaluation for initial diagnosis with FDG-PET (P<0.005) 1. Agreement rate or accuracy rate is 88.9%. 2. Sensitivity is 95.2%, and specificity 66.7%. 3. Positive predictive rate is 90.9%, and negative predictive rate 80.0%. 4. In consideration of tumor stage, diagnostic rate in less than stage II was 90% and in greater than stage III 100%. 5. In consideration of tumor size, diagnostic rate in less than T2 was 92.3% and in greater than T3 100%. After primary treatment, evaluation for follow up check with FDG-PET (P < 0.001) 1. Agreement rate or accuracy rate is 85.4%. 2. Sensitivity is 87.5%, and specificity 82.4%. 3. Positive predictive rate is 87.5%, and negative predictive rate 82.4%. 4. In 24 recurred cases, 6 had distant metastasis, and 5 of them were diagnosed with FDG-PET, resulting in diagnostic rate of FDG-PET of 83.3%. From the above results, Positron Emission Tomography with [18F]- Fluorodeoxyglucose appears to be more sensitive and accurate for detecting the presence of oral and maxillofacial tumors, and has various clinical applications such as early diagnosis of tumor in initial and follow up check and detection of distant metastasis.

Background: This study examined the psychometric properties of the Bahasa Malaysia (BM) version of the European Organization for Research and Treatment of Cancer (EORTC) Colorectal Cancer-specific Quality Of Life Questionnaire (QLQ-CR29). Materials and Methods: We studied 93 patients recruited from University Malaya and Universiti Kebangsaan Medical Centers, Kuala Lumpur, Malaysia using a self-administered method. Tools included QLQ-C30, QLQ-CR29 and Karnofsky Performance Scales (KPS). Statistical analyses included Cronbach's alpha, test-retest correlations, multi-traits scaling and known-groups comparisons. A p vaue ${\leq}0.05$ was considered significant. Results: The internal consistency coefficients for body image, urinary frequency, blood and mucus and stool frequency scales were acceptable (Cronbach's alpha ${\alpha}{\geq}0.65$). However, the coefficients were low for the blood and mucus and stool frequency scales in patients with a stoma bag (${\alpha}=0.46$). Test-retest correlation coefficients were moderate to high (range: r = 0.51 to 1.00) for most of the scales except anxiety, urinary frequency, buttock pain, hair loss, stoma care related problems, and dyspareunia (r ${\leq}0.49$). Convergent and discriminant validities were achieved in all scales. Patients with a stoma reported significantly higher symptoms of blood and mucus in the stool, flatulence, faecal incontinence, sore skin, and embarrassment due to the frequent need to change the stoma bag (p < 0.05) compared to patients without stoma. None of the scales distinguished between patients based on the KPS scores. There were no overlaps between scales in the QLQ-C30 and QLQ-CR29 (r < 0.40). Conclusions: the BM version of the QLQ-CR29 indicated acceptable psychometric properties in most of the scales similar to original validation study. This questionnaire could be used to complement the QLQ-C30 in assessing HRQOL among BM speaking population with colorectal cancer.

This descriptive study was done to identify factors influencing sexual satisfaction in women who had had a hysterectomy and to compare these with women who had not had a hysterectomy. The purpose was to contribute theoretical understanding on which to base nursing care planning. One group of subjects were 156 women who had had a hysterectomy, between one and 18 months post surgery, living with their spouse, having no complications, and menstruating before surgery. The other group of subjects were 282 healthy women who were living with their husbands and menstruating. The study tool consisted of 108 items including item concerning personal characteristics, characteristics related to the hysterectomy, husband's support, body image, emotions, attitude toward the sexual relationship, knowledge of sexuality, sexual behavior, and sexual satisfaction. Sexual satisfaction was measured by a tool based on Derogatis Sexual Function Inventory. The range of the internal level of the study tool was from. 5208 to .9462. Data collection was done during the period from June 20 to Aug.20, 1989. The same questionnaire was used of data collection for both groups, but a mail survey method was used for the women who had had a hysterectomy, and an interview method was used for the women who had not had a hysterectomy. Data analysis was done using frequency, ratio, mean and S.D. for the characterstics of the subjects and level of sexual satisfaction. t - test or ANOVA was used for the differences between the groups with regard to the general and hysterectomy related characteristics. The relationship between the score for sex life related factors and the level of sexual satisfaction was analyzed using the Pearson Correlation, and the influencing factors on sexual satisfaction were analyzed by stepwise multiple regression. The results of this study were as follows ; 1. Mean age and income level were the only general characteristics for the two groups that were significantly different. The mean age, and income level of the group who had had a hysterectomy were 45years, and 1,150,000 won respectively, and for those who had not had a hysterectomy, 41 years and 999,000 won. 2. There was no statistical difference of the sexual satisfaction score between the two groups. 3. There was differences in the factors influencing sexual satisfaction between the two groups. Factors influencing sexual satisfaction for the group who had had a hysterectomy were husband's support (R＝.5793, P＝.000) and the women's Knowledge of sexuality(R＝.6670, P＝.000) (total variance : 33.56). On the other hand, emotional status(R＝.4294, P＝.000), sexual behavior(R＝.4294, P＝.000), husband's support(R＝.5274, P＝.000) and attitude towards sexual relations (R＝.5412, P＝.000) (total variance : 54.12) were the factors influencing sexual satisfaction in the group who had not had a hysterectomy. Since husband's support and sexuality knowledge were identified as factors influencing sexual satisfaction of women who have had a hysterectomy, it can be concluded that, before a woman who has had a hysterectomy is discharged from hospital, nurses should include strategies in the nursing care plan that will promote husband's support and the women's knowledge of sexuality.

A central issue in the development of nursing practice is to describe the phenomenon with which nursing is concerned. To identify the health problems which can be diagnosed and managed by the nurse is the first step to organize and ensure the development of nursing science. Therefore the academic world has been discussing the application of the nursing diagnosis in nursing practice as a means of improving quality of care. The objectives of this study were to develop a standardized nursing care plan for ten selected nursing diagnoses to form a database for computerized nursing service. The research approach used in the study was (1) the selection of the ten nursing diagnoses which occur most frequently on medical-surgical wards, (2) the development of a standardized nursing care plan for the ten selected nursing diagnoses, (3) application of the plan to hospitalize patients and evaluation of the content validity by the nurses, and (4) evaluation of the clinical effects after the use of the standardized nursing care plans. The subjects were 56 nurses and 395 hospitalized patients on two medical and two surgical unit. The results of this study were as follows ; 1) The ten selected nursing diagnoses for the development of the standardized nursing care plans were “PAIN, SLEEP DISTURBANCE, ALTERED HEALTH MAINTENANCE, ALTERATION IN NUTRITION, ANXIETY, CONSTIPATION, ALTERED PATTERNS OF URINARY ELIMINATION, DISTURBANCE IN BODY IMAGE, POTENTIAL FOR ACTIVITY INTOLERANCE AND ACTIVITY INTOLERANCE”. 2. The developed standardized nursing care plans included the nursing diagnosis, definition, defining characteristics, etiologic or related factors that contribute to the condition, recording pattern, desired outcomes and nursing orders (nursing interventions). 3. The plan was used with hospitalized patients on medical - surgical wards to test for content validity. The patient's satisfaction with the nursing care and nurses' job satisfaction were investigated to evaluate the clinical effects after the use of the standardized nursing care plans. A comparison of patient satisfaction with nursing care before and after the introduction of the standardized nursing care plans showed a statistically significant higher level of satisfaction with the standardized care plans. There was no difference in the level of job satisfaction expressed by the nursing staff before and after the standardized nursing care plans were introduced. However, when opinions about the use of the standardized nursing care plans were examined it was found that there was a positive effect on clarity in defining the nursing problems, determining nursing cost, more feasible goal setting, effective and systematic nursing records and indications for nursing research. The results of this study suggest that in order to increase the use of nursing diagnoses in the clinical area, it would be effective to select some wards as a pilot project, give the nurses training in the use of nursing diagnosis and develop and use the standardized nursing care plans. In addition to the ten diagnosis used in this study it is recommended that continual development of nursing diagnoses be done using diagnoses that are appropriate to Korea and testing them for validity through standardized care plans.

When underwater rubble leveling work is carried out by a robot, real-time information on the topography around the robot is required for remote control. If the topographical information with respect to the current position of the robot is displayed as a 3D graphic image, it allows the operator to plan the working schedules and to avoid accidents like rollovers. Up until now, the topographical recognition was conducted by multi-beam sonars, which were only used to assess the quality before and after the work and could not be used to provide real-time information for remote control. This research measures the force delivered to the bucket which presses the mound to determine whether contact is made or not, and the contact position is calculated by reading the cylinder length. A variable bang-bang control algorithm is applied to control the heavy robot arms for the positioning of the bucket. The proposed method allows operators to easily recognize the terrain and intuitively plan the working schedules by showing relatively 3-D gratifications with respect to the robot body. In addition, the operating patterns of a skilled operator are programmed for raking, pushing, moving, and measuring so that they are automatically applied to the underwater rubble leveling work of the robot.

Objectives A growing body of evidence has suggested that morphologic changes in cerebellum may be implicated with pathophysiology of major depressive disorder (MDD). The aim of this study is to investigate a difference in the volume and cortical thickness of the specific region of cerebellum between patients with MDD and healthy controls (HC). Methods A total of 127 patients with MDD and 105 HC participated in this study and underwent T1-weighted structural magnetic resonance imaging. We analyzed volume and cortical thickness of each twelve cerebellum regions divided by left and right and the volume and cortical thickness of the whole cerebellum from T1-weigted image of participants. One-way analysis of covariance was used to investigate the volume and cortical thickness difference of total and specific regions between two groups adjusting for age, gender, medication, and total intracranial cavity volume. Results We found that the patients with MDD had significantly greater volume in the left cerebellum lobule III region [false discovery rate (FDR)-corrected p = 0.034] compared to HC. Also, our findings indicate that cortical thickness of left lobule VIIB (FDR-corrected p = 0.032) and lobule VIIIB (FDR-corrected p = 0.032) are significantly thinner in the patients with MDD compared with the HC. No significant volume and cortical thickness differences were observed in other sub-regions of the cerebellum. The volumes and cortical thickness of whole cerebellum between patients with MDD and HC did not differ significantly. Conclusions We observed the region-specific volume and cortical thickness difference in cerebellum between the patients with MDD and HC. The results of our study implicate that the information about structural alterations in cerebellum with further replicative studies might provide a stepping stone toward a specific marker to diagnose MDD.

Background: Colorectal ranked first among cancers reported in males and ranked second amongst females in Jordan, accounting for 12.7% and 10.5% of cancers in males and females, respectively. Colorectal cancer patients can suffer several consequences after treatment that include pain and fatigue, constipation, stoma complications, sexual problems, appearance and body-image concerns as well as psychological dysfunction. There is no published quantitative data on the health-related quality of life and psychological wellbeing of Jordanian colorectal cancer survivors. Method: This project was a cross-sectional study of colorectal cancer survivors diagnosed in 2009 and 2010. Assessment was performed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the colorectal cancer specific module (EORTC QLQ-CR 29) and the Hospital Anxiety and Depression Scale (HADS). Data on potential predictors of scores were also collected. Results: A total of 241 subjects completed the study with mean age of $56.7{\pm}13.6$. Males represented 52.3% of study participants. A majority of participants reported good to high overall health; the mean Global health score was $79.74{\pm}23.31$ with only 6.64% of study participants scoring less than 33.3%. The striking result in this study was that none of the study participants participated in a psychosocial support group; only 4 of them (1.7%) were even offered such support. The mean scores for HADS, depression score, and anxiety score were $8.25{\pm}9$, $4.35{\pm}4.9$ and $3.9{\pm}4.6$, respectively. However, 77.1% of study participants were within the normal category for the depression score and 81.7% were within this category for anxiety score; 5.4% of participants had severe anxiety and 5.4% of them had severe depression. Discussion: Patients with colorectal cancer in Jordan have a good quality of life and psychological wellbeing scores when compared with patients from western countries. None of the colorectal cancer patients managed at the Ministry of Health received any formal counselling, or participated in psychological or social support programmes. This highlights the urgent need for a psychosocial support programme, psychological screening and consultations for patients diagnosed with colorectal cancer at the Ministry of Health Hospitals.

The purpose of this paper is to implement a multiple bio-signal central monitoring system based on textile fabrics flexible platform which can obtain and monitor bio signals(heart rate, body temperature, electrocardiography, electromyogram) of workers in special working environments and additional situational information (3-axis acceleration, temperature, humidity, illumination, surrounding image). This system can prevent various accidents that may occur in the remote work environment and provide fast and efficient response by detecting workers' situations in real-time. For it, the textile fabrics flexible platform was made as innerwear or outerwear so that it does not interfere with workers' performance while collecting bio-signal and situational information, and obtained information is sent to the central monitoring system through wireless communication. The central monitoring system is based on wireless medical telemetry service of WMTS (Wireless Medical Telemetry Service); can monitor from 2 to 32 people simultaneously; and was designed so that it can be expanded. Also, in this study, to verify performance of the WMTS communication model, packet transmission rates were compared according to the distance.

For patients receiving chemotherapy and radiation therapy treatment progresses as vomiting, nausea, weight of the patient because of a loss of appetite it is reduced. The patient's weight and the distance from the skin and the treatment site is expected to be closer, thereby reducing the change in the skin because of this dose. This study tests using a loose see the difference between the volume change appears as the weight of the patient using the same phantom and the phantom body of the patient. To using the same as the position EBT film is attached to the skin of the treatment site and was adjusted to the thickness of the Bolus. And using a computerized treatment planning only tomotherapy equipment was passed under the conditions according to the thickness of the radiation dose. To baseline for accurate reproduction position using the MVCT was applied to treated with verification. By passing a total of three dose reduced the error, it was a measure of the film by using a dedicated scanner, EBT VIDAR scanner. Got an increase in the skin dose is displayed each time the thickness of the bolus reduced, in a bolus was completely removed with the highest value. If the changes appeared dose was greater weight loss patients to chemotherapy and therefore bolus thickness variation considering the weight loss of the patient when applying the tomotherapy of nasopharynx cancer was found that the increase in skin dose be increased. This large patient before treatment due to weight loss over the image verification is considered to be established should consider how to re-create your mask and treatment plan for fixing it.
