Objectives: The aim of this study was to determine the incidence and characteristics of second primary malignancy (SPM) in patients with head and neck squamous cell carcinoma treated at a tertiary care hospital. Materials and Methods: We retrospectively reviewed the medical records of 221 patients who underwent surgery with or without adjuvant treatment for head and neck cancer from 2000 to 2002. Data of age, sex, risk factors, sites of primary and SPM, TNM stage of primary tumor, incidence of SPM, and survival were collected from medical charts. Results: Eighteen patients developed SPM during a median follow-up of 67 months, with an overall incidence of 8.14%. In addition, 77.7% of SPMs occurred in the oral cavity, followed by 11% in the lungs. The 5-year overall survival after the diagnosis of SPM in the head or neck was 70%, compared to 30% for SPM in other body regions. Conclusion: Considering a high incidence of SPM, i.e., 8.14%, in a mean follow-up period of 67 months suggests the need for long-term follow-up. Since treatment of SPM has shown an acceptable survival rate, early detection and curative therapy should be emphasized.

Neurodevelopmental outcomes of very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI) in Korea on 14 reports from 1984 to 2008 were analyzed. Follow-up rates were varied from 42.9% to 90.2%. Duration of follow-up ranged from 4 months to 5 years. The prevalence of cerebral palsy (CP) of VLBWI was as follows: 4.3-5.3% in 1980s, 7.1-9.1 % in 1990s and 3.6-15.6% in 2000s. CP was noted in 8.2-30.8% of ELBWI on studies reported in 2000s. Delayed Mental development was diagnosed in 2.0-17.9% of VLBWI and in 20.4-30.8% of ELBWI. Sensory impairments such as hearing loss or visual deficit were reported in 3.1-3.6% of VLBWI and 0.0-10.0% of ELBWI. Seizure disorder was reported in 5.3% of VLBWI by one report. No reports for minor neurodevelopmental dysfunctions in VLBWI and ELBWI were found from 1984 to 2008. It is necessary to establish basic protocols and nationwide systems for long-term follow-up study to obtain valuable data.

Purpose: To evaluate the effects of a follow-up program for breast cancer patients after surgery. Method: A quasi-experimental design was used. The subjects were 56 breast cancer patients (experimental group: 27, control group: 29). The subjects of the experimental group participated in the Follow-up program of 7 sessions once a week, during 4 weeks including one telephone visit. The program consisted of health education of breast cancer, exercise, lymph edema prevention, diet education, theraband rehabilitation exercise, laugh therapy, and breast self examination. The obtained data were analysed by using the ANCOVA of SPSS. Results: There was a significant difference in the scores of physical wellbeing, symptom distress and mood state between the two groups. Conclusion: Considering these research results, short-term intervention could improve physical and emotional functioning abilities by helping better health. Nurses should establish and manage a proper program to provide multipurpose support and it must apply the program after surgery as soon as possible for breast cancer women.

Objectives: To analyze the association between changes in perceived physical and psychosocial working conditions and change of sickness absence days in younger and older (< 50 and ${\geq}50$ years) food industry employees. Methods: This was a follow up study of 679 employees, who completed working conditions survey questionnaires in 2005 and 2009 and for whom the requisite sickness absence data were available for the years 2004 and 2008. Results: Sickness absence increased and working conditions improved during follow-up. However, the change of increased sickness absence days were associated with the change of increased poor working postures and the change of deteriorated team spirit and reactivity (especially among < 50 years). No other changes in working conditions were associated with the changes in sickness absence. Conclusion: Sickness absence is affected by many factors other than working conditions. Nevertheless, according to this study improving team spirit and reactivity and preventing poor working postures are important in decreasing sickness absence.

The ISO 9000 Follow-up Management Practices (FMP) as an integrated area including training, QM systems, management commitment, customer focus, communication and related issues are examined. A sample of 191 small and medium-sized firms data from mail survey is analyzed by the SPSSWIN. A model of FMP including three factors (Systems, Training, and Customer Focus) is introduced. In this paper, a focus is laid on the comparison between ISO 9000:1994 vs. ISO 9000:2000 or 05 9000 certificates and between groups classified by the time length after certification, and on regression relationships between FMP level and business performance. The result shows that the difference of FMP level is significant between two versions and between groups. Quality level and system satisfaction are influenced significantly by the three factors.

The clinical significance of ground-glass nodules (GGNs) has been investigated in extensive clinical research for many years. The natural history of GGNs is known to be closely related to their size, proportion of solid components, and size progression over time. Based on these data, several guidelines for GGN management have been published worldwide. The indications for nonsurgical biopsy or surgical resection of GGNs are as follows: pure GGNs between 5 and 10 mm in size if they increase in size or show development of a solid component at follow-up, pure GGNs >10-15mm that remain stable but persistent, part-solid nodules >8 mm persisting at follow-up, or part-solid nodules with a solid component >6 mm at follow-up. Newly updated data considering geographical or racial factors and recent developments in surgical techniques may improve the surgical indications for GGNs in the near future.

Background : We aimed to determine the effect of a mental practice on the electromyography (EMG) activity of the quadriceps femoris muscle of the affected side in a hemiplegic patient during sit-to-stand and stand-to-sit tasks. Methods : We recruited a male patient who had suffered from right hemiplegia. A single-subject experimental A-B-A design was used. The reliability of visual analysis, which was primarily employed in this study design, was supported by using the "2- standard-deviation band" method. The target motions consisted of two activities: sit-to-stand and stand-to-sit. The EMG measurements of the quadriceps femoris muscles of the affected and unaffected sides were made in 8 sessions in the baseline (A), mental-practice (B), and follow-up (A) phases. During the mental practice phase, the 10-min mental practice was performed, and the mental practice was withdrawn in the follow-up phase in order to identify the carry-over effects of the treatment. Data was calculated as the percentage of the ratio of the quadriceps EMG activity values of the affected side on unaffected side. Result : The percentage EMG-activity ratio showed a greater increase in the mental-practice phase than in the baseline, and it was maintained during the follow-up phase. Most of the data points in the mental-practice and follow-up phases were positioned above the "2-standard-deviation band." Conclusion : These findings suggest that mental practice can be used to improve the physical function of hemiplegic patients.

Objective : Percutaneous vertebroplasty (VP) can provide immediate stabilization in pathologic fractures of spinal tumors. However, long term follow-up data in cases of pathologic fractures are lacking. The authors report follow-up results of VP in 185 pathologic fractures of 102 spinal tumor patients. Methods : Percutaneous VP was performed at 185 vertebral bodies of 102 patients from 2001 to 2007. Retrospective analysis was done with medical records and radiological data. The change of visual analogue score (VAS), vertebral body (VB) height and kyphotic angle were measured preoperatively and on postoperative one day and at 3, 6, and 12 months. Results : The patients were composed of metastatic spine tumors (81%) and multiple myeloma (19%). Involved spinal segments were between T6 and L5. Mean follow-up period was 12.2 months. VAS for back pain was 8.24 preoperatively, 3.59 (postoperative one day), 4.08 (three months) and 5.22 (one year). VB compression ratio changed from 21.33% preoperatively to 13.82% (postoperative one day), 14.36% (three month), and 16.04% (one year). Kyphotic angle changed from $15.35^{\circ}$ preoperatively to $12.03^{\circ}$ (postoperative one day), $13.64^{\circ}$ (three month), and $15.61^{\circ}$ (one year). Conclusion : Immediate pain relief was definite after VP in pathologic compression fracture of osteolytic spinal disease. Although VAS was slightly increased on one year follow-up, VP effect was maintained without significant change. These results indicate that VP could be a safe and effective procedure as a palliative treatment of the spinal tumor patients.
