Voluntary habitual dislocation of the hip is very rarely reported in children, and only 13 cases have been reported in the literature. We add a new case in a 5 year old boy. The boy did not have previous history of trauma, skeletal and/or soft tissue anomalies, nor known connective disease. He was treated by intertrochanteric varusinward rotation osteotomy of the affected hip on February 25, 1985 and was followed until January 11, 1993. Postoperative convalescence was uneventfully successful, and the hip developed well without any obvious dysplasia at the latest follow-up.

PURPOSE: This study was conducted to develop health education program components for early childhood and to investigate teachers' awareness of the importance of health education and their performance rate of health education. METHODS: Early childhood health education program components were developed using two rounds of the Delphi method. The Delphi group consisted of 21 experts in childhood education. After health education program components were developed, they were used in surveying child care teachers' awareness of importance and performance rate and 151 teachers sampled from 30 child care centers participated in the survey. RESULTS: The early childhood health education program components consisted of 5 areas, 16 subjects and 33 specific contents. Early childhood teachers' awareness of importance was over 4.5 points in all the areas and in 11 out of the 16 subjects. The most frequently educated subjects were 'the importance of hand washing' and the least frequently educated subject was 'obesity prevention'. The teachers' awareness of importance and their performance rate of specific contents were high in 'maintaining order' and 'using children's rides safely,' and low in 'obesity prevention' and 'infectious disease prevention.' CONCLUSION: The components of this health program were developed in consideration of field feasibility and the relationship of health program education in elementary, middle and high school.

PURPOSE: This study was to investigate the relationship between the level of emotional labor and occupational job stress of hospital nursing staff. METHODS: The survey was conducted from Mar. to Oct. 2009 to collect data from clinical nurses (N=496). RESULTS: The study showed that nurses without religion and those working in big-sized hospitals had higher scores in emotional labor, and those of 26~30 years old felt the highest stress in the occupational role. The same applied to the married, more work experienced, atheist and those working in big-sized hospitals. Unmarried, under educated nurses with less work experience working in the big-sized hospitals showed higher scores in personal strain. The scores of the personal resources depended on religion, work experience, marital status and position of their jobs. Emotional labor was positively correlated with an occupational role and personal strain, respectively, but the emotional labor, occupational role and personal strain were negatively correlated with personal resources respectively. CONCLUSION: Intervention program is required to reduce overload of nurse's role and to relieve physical and psychological strains of the under-30-age-group. Also, social support and rational/cognitive coping must be reinforced.

PURPOSE: The purposes of this study were to examine the amount of daily fluid intake among nursing home residents and to explore the caregiver's perceived barriers to elderly's fluid intake. METHOD: Data was collected from 111 nursing home residents and 64 caregiver's in 4 nursing homes. A random, non-consecutive three days of 24 hour fluid intake was measured and recorded. The caregiver's perceived barriers to elderly's fluid intake was assessed using a structured questionnaire. RESULTS: The average amount of daily fluid intake was 1,035(SD=359)ml with the range of 210ml to 2,050ml. About 52% (n=58) of the subjects had a less than adequate fluid intake. The amount of daily fluid intake was significantly associated with age, mental status, physical functioning, and the number of oral medications ordered. The most frequently mentioned caregiver's perceived barrier was elderly's concern about incontinence with increased fluid intake. CONCLUSION: Inadequate fluid intake among nursing home residents is prevalent. To enhance adequate hydration of nursing home residents, an institution wide nursing intervention is necessary.

OBJECTIVES: In this study we performed an analysis of the stress associated with the working conditions of 6,764 workers based on 'A survey of healthy condition of workers on 1999'by the Korean Occupational Safety and Health Agency. The Purpose of this study was to provide basic data for health education and management for industrial workers'health promotion. METHODS: Collected data were analyzed using the t-test, ANOVA and multiple regression analysis, using the SPSS 10.0 program. RESULTS: When the degrees of stress were analyzed according to demographic characteristics, females were found to have higher levels of stress than males (p<0.001). Furthermore, as age was lowered and as the work space became larger, the degrees of a stress were also found to be higher (p<0.001 and p<0.01, respectively). When the degrees of stress were analyzed according to working conditions, longer working hours (p<0.001) and reduced break times (p<0.05), gave rise to higher degrees of stress. Also, as the work space was reduced in size and as the work intensity was augmented, the degrees of a stress were made higher (p<0.01). In terms of physical working conditions, humidity and a lack of sense of security resulted in higher degrees of stress (p<0.01). When the workers sense that their environment is noisy or dusty has poor lighting or ventilation or that the rest room and cafeteria facilities are inadequate, the degrees of stress are found to be higher. As regards the social environment, when the workers sensed that the degree of job demand or job control was higher or that the degree of social support was lower, the degrees of stress were increased (p<0.001). Among those factors which influenced physical stress in the stepwise multiple regression analysis, the primary factor was found to be the safety of the working place (5.1 %). Other factors which influenced physical stress were degree of job demand, age, work intensity, humidity, sexual discrimination, length of working hours, size of work space and the existence or not of a regular break time in this order. Total R2 due to these factors was 12%. Among those factors which influenced mental stress in the stepwise multiple regression analysis, the primary factor was the degree of job demand (4.8 %). Other factors which influenced mental stress were humidity, age, sexual discrimination, the degree of a job control, safety of the working place, degree of social support, a working site, size of the work space, quality of lighting, the existence or not of a regular break time and length of working hours in this order. Total R2 due to these factors was 13.1 %. CONCLUSIONS: The above results shows that working conditions are strongly related to stress. Furthermore, when both physical and social working conditions are continuously managed and improved, workers may not only reduce their levels of stress but also maximize their working efficiency.

Five adult cases of post-laminectomy swan-neck deformity are reported. The factors causing the deformity, prophylactic measures, and treatment of the deformity are discussed. It is strongly adviced to the neurosurgeons and orthopedic surgeons that they should be aware of this unwanted complication of the multi-level cervical laminectomies, and that they should provide every preventive measures before post-laminectomy swan neck deformity develops. Anterior interbody fusion spanning the entire unstable segments is preferably recommended together with application of pre-fusion traction.

OBJECTIVES: Fatigue is a primary human factor for decreased job performance in the workplace. It is well documented that drowsiness is a typical symptom of fatigue and is closely associated with commercial drivers'safety and well-being. However, few studies have been conducted to develop or validate fatigue symptom instruments for a working population. The main purpose of this study was to develop a general fatigue checklist and a driving fatigue checklist for Korean commercial drivers. METHODS: A total of 287 bus drivers in a commercial transportation company participated in a self-administered survey that was designated Study 1. Based on the statistical results of Study 1, a focus meeting with 16 professional consultants was conducted to revise the fatigue symptom instrument for Study 2. In Study 2, 288 commercial drivers (156 bus drivers and 132 truck drivers) participated in the revised questionnaire survey. All collected responses were entered into a SPSS worksheet and the data analysis was conducted using SPSS software 11.1. The exploratory factor analysis used in this study followed the principle component factoring rule and the varimax rotation method for factor extraction. The criteria for item selection were an Eigen value of 1.0 or greater, a communality score of .50 or greater, and no 'fence rider'property over the extracted factors. RESULTS: Through Study 1, the consultant meeting, and Study 2, a general fatigue checklist was developed with a total of 3 factors and 11 items, and a driving fatigue checklist was developed with 2 factors and 10 items. The 3 factors of the general fatigue checklist were physical fatigue, psychological fatigue, and chronic tiredness. The two factors of the driving fatigue checklist were physical fatigue and perceptive and functional fatigue. CONCLUSIONS: The primary contents of general fatigue were different from those of driving fatigue according to the two fatigue instrument factors developed in this study. The primary fatigue symptoms of the commercial driving population were identified as physical fatigue and perceptive and functional fatigue.

PURPOSE: Cytokines, hormones and growth factors use signal transducers and activators of transcription (STAT) signaling pathways to control various biological responses, including development, differentiation, cell proliferation and survival. STAT3 and 5 help promote cell cycle progression and cellular transformation and prevent apoptosis. In this research, the presence of STAT3 and STAT5 activation and their association with pathological features and clinical outcome in renal cell carcinoma cases were studied. MATERIALS AND METHODS: Using immunohistochemistry with rabbit polyclonal anti-STAT3 and STAT5 antibodies, forty-eight paraffin-embedded renal cell carcinoma specimens were examined for the activation status of STAT3 and STAT5. Cells of which 10% or more were left with a dark brown stains in the nucleus were regarded as positive tumor cells. The activation status of STAT3 and STAT5 were compared with the clinicopathological variables. RESULTS: Significant associations of STAT3 activation with tumor size, T-stage, distant metastases and low survival rate were observed (p<0.05); and in STAT5, significant associations with distant metastases and low survival rate were observed (p<0.05). CONCLUSIONS: The results of this study strongly suggest that the activation of STAT3 and STAT5 contribute to the development and progression of the renal cell carcinoma.

STATEMENT OF PROBLEM: when using resin for class II restoration, micoleakage by instrumentation can be regarded as the primary negative characteristic. A review of the available literature suggests that using flowable resin as liner to decreased microleakage. PURPOSE: The aim of this study was to determine the influence of the nanofilled flowable resin lining on marginal microleakage after load cycling in class II composite restoration fillings using nanofiller resin. MATERIAL AND METHODS: 24 extracted premolars were prepared with class II cavity. F group was restored the nanofilled resin with the nanofilled flowable resin as liner. NF group was restored the nanofilled resin only. After restoration, an experiment was performed on 2 groups using a 300N load at 104, 105 and 106 cycles. Prior to and before each load cycling, it was gauged length on total marginal microleakage, axial marginal microleakage and buccal, gingival, lingual marginal microleakage. Data were analyzed with the Mann-Whitney test & Kruskal-Wallis test. RESULTS: There were statistically significant differences between 2 groups and between individual groups. (P < .05) The result showed less microleakage in teeth restored by the nanofilled resin, which was lined by the nanofilled flowable resin. CONCLUSION: There was significant reduction in microleakage when the nanofilled flowable resin lining was placed underneath the nanofilled resin in class II composite restoration fillings.
