Objective : We compared the clinical and radiographic outcomes of stand-alone polyetheretherketone (PEEK) cage and Zero-Profile anchored spacer (Zero-P) for single level anterior cervical discectomy and fusion (ACDF). Methods : We retrospectively reviewed 121 patients who underwent single level ACDF within 2 years (Jan 2011-Jan 2013) in a single institute. Total 50 patients were included for the analysis who were evaluated more than 2-year follow-up. Twenty-nine patients were allocated to the cage group (m : f=19 : 10) and 21 for Zero-P group (m : f=12 : 9). Clinical (neck disability index, visual analogue scale arm and neck) and radiographic (Cobb angle-segmental and global cervical, disc height, vertebral height) assessments were followed at pre-operative, immediate post-operative, post-3, 6, 12, and 24 month periods. Results : Demographic features and the clinical outcome showed no difference between two groups. The change between final follow-up (24 months) and immediate post-op of Cobb-segmental angle (p=0.027), disc height (p=0.002), vertebral body height (p=0.033) showed statistically better outcome for the Zero-P group than the cage group, respectively. Conclusion : The Zero-Profile anchored spacer has some advantage after cage for maintaining segmental lordosis and lowering subsidence rate after single level anterior cervical discectomy and fusion.

The purpose of this study was to identify the relationship between the nursing organizational characteristics and job satisfaction. Subjects were 362 nurses at a general hospital in Seoul. Data were collected from November 1, 1999 to November 31, 1999 with the structured questionnaires and analyzed by $SPSS-PC^+$ 8.0 for descriptive statistics, ANOVA, Pearson correlation, and stepwise multiple regression. The results were as follows; 1. The average score of the nursing organizational characteristics was 3.7. The score of head nurse's leadership was highest and supervisor's was lowest. The average score of the job satisfaction was 3.1 and was similar to the results of other studies. 2. Being regarded to the nursing organizational characteristics and job satisfaction by general demographic variables, The head nurse's leadership, the supervisor's leadership and interaction, and the overall nursing organizational characteristics showed significant differences by year of career, position status, and service-department(p<.1, p<.05). The job satisfaction showed significant difference by position status(p<.01). 3. There were correlations between the nursing organizational characteristics and job satisfaction(r=0.358-0.815). 4. The most important variable in the job satisfaction was 'organizational climate' and it was explained 32.0% out of the total variance of job satisfaction and 'all of nursing organizational characteristic factors' explained 47.5%. According to the results of this study, the suggestions were as follow: 1. To improve nurses' job satisfaction, the strategy for the development of the cooperative nursing organizational climate and for the strengthening of 'the nursing manager's leadership and interaction' in the nursing department are necessary. It should to be considered the differences in the nursing organizational characteristics and job satisfaction by nursing manager and staff nurses. 2.

In the context of domestic consumption environment changes such as expansion of smartphones and increase of single-person households, hypermarket, which was the mainstream of the existing retail market, have recorded negative growth for the last three years due to declining sales. And it is not enough to analyze the influence relationship with other retail channels or investigate the cause of consumption movement. In this study, we analyzed the decline in the growth rate of hypermarket by demographic variables, consumption time, etc. And logistic regression analysis revealed the relationship between the decrease in consumption of hypermarket and the change in the proportion of sales of other retail channels. In addition, we surveyed consumers who have decreased consumption of hypermarket based on actual card consumption data to determine why they choose different retail channels. This is significant in that the result of quantitative analysis of changes in retail channel consumption and the result of qualitative reasoning converged to give a stereoscopic view of consumption.

Purpose: The purpose of this study was to describe sports injuries among elderly people and to compare physical activity, perceived health status and exercise self-efficacy between elderly people who had experienced a sports injury and elderly people who hadn't. Methods: The sample of this study were 100 elderly in Korea, 51 of whom had had a sports injury. The study used questionnaires to gather data. There were 8 demographic factors, 4 factors related to physical activity, perceived health status and exercise self-efficacy of the subjects. Data were analyzed by frequencies, chi-square test, and t-test. Result: Among the sports injured elders, one occurrence of a sport injury was 86.3%. There were more outdoor than indoor sports injuries of elders (66.7%), and sports injuries of elders occurred more in the winter (82.7%). The major cause of the sports injuries was loss of balance. Ankles were frequently damaged from these injuries. The most significant change after the sports injury was reduction of physical activity (60.8%). There were significant differences between sports injured elderly and non-injured elderly for age (${\chi}^2=2.58$, p=.011) and the amount of physical activity (t=1.96, p=.050), but there was no significant difference in perceived health status and exercise self-efficacy. Conclusion: To prevent sports injuries in the elderly means to maintain a medium level of physical activity and to improve their balance.

Objectives: We evaluated and recorded post-traumatic and postoperative neurosensory deficits of the inferior alveolar nerve (IAN) in mandibular fracture in order to identify associated risk factors. Materials and Methods: This was a prospective cohort study composed of 60 patients treated for mandibular fracture. The primary study variable was the change between the post-traumatic IAN neurosensory examination score and the score after fracture reduction. Risk factors were categorized as demographic, anatomic, fracture displacement, and treatment. Appropriate descriptive and bivariate statistics were computed. Results: Sixty patients with unilateral mandibular fracture reported within 24 hours of injury were evaluated over a one-year period. A post-traumatic neurosensory deficit was observed in 52 patients (86.7%), the percentage of which was reduced to 23.3% over the follow-up period. Abnormal postoperative neurosensory scores were significantly higher in angle fracture cases (33.3%) compared to body fracture cases (11.1%). When recovered and non-recovered neurosensory scores were compared by fracture location, 88.9% of body fracture cases showed significant recovery compared to 66.7% of mandibular angle fracture cases. Cases with less than 5 mm fracture displacement showed statistically significantly higher neurosensory recovery scores (90.6%) compared to those with more than 5 mm fracture displacement (60.7%). Conclusion: Use of a miniplate with mono-cortical screws does not play a role in increasing IAN post-traumatic neurosensory deficit. Early management can reduce the chances of permanent neurosensory deficit. Mandibular fracture displacement of 5 mm or more and fracture location were found to be associated with an increased risk of post-traumatic IAN neurosensory score worsening.

This paper deals with how Korean television musical variety show rose and declined focusing the 'Show Show Show'. 'Show Show Show' was a Korean television musical variety show that ran on TBC-TV every Saturday night at 8pm. until TBC-TV was absorbed into KBS-TV in 1980. Its musical acts, of various kinds, were interspersed with comic turns and special items including dancing, mime, magic, and acrobat. Korean television musical variety show worked on what audiences had in common across generational divides till the late 1970s. 'Show Show Show's catchall format didn't cross the demographic lines like it used to. But the young generation demanded music program that spoke to their own condition in the early 1980s. 'Show Show Show' ended on KBS-TV in July 1983 through the influence of the absorption of TBC-TV into KBS-TV and the changes of cultural circumstances. The decline of the television musical variety show was attributable to the fragmentation of musical taste and the change of viewing behaviors.

Objective : Several studies have reported the association between posttraumatic stress disorder (PTSD) and hypertension (HTN). The aim of this study was to evaluate the impact of PTSD symptoms on blood pressure. Methods : Korean veterans of the Vietnam War with (n=62) or without PTSD (n=87) participated in this study. The clinician administered PTSD scale (CAPS) and alcohol use disorder identification test (AUDIT) were applied. Blood pressure, pulse rate, risk factors of HTN and demographic data of the subjects were collected. Effects of potential explanatory variables on HTN were analyzed with logistic regression. Results : Diastolic blood pressure was significantly higher in PTSD group (p=0.015). However, PTSD subjects showed significantly lower pulse rate than non-PTSD subjects (p=0.004). Logistic regression analysis showed that avoidance symptom might be a predictor for hypertension (OR=1.065, p=0.030). Conclusion : These results suggest that PTSD, especially avoidance symptom, might be a risk factor on HTN in the elderly with PTSD. Further studies are needed to evaluate the change of blood pressure according to the clinical improvement of PTSD.

Purpose: Nowadays the Korean society is in the center of time of the social change. Because of dissociation of traditional family, IMF (International Monetary Fund) crisis and economic recession, the mortality rate of suicidal attempts are increasing annually. The majority of suicidal attempts were by poisoning considering the characteristics of korean society. Therefore we studied to find out the characteristics of suicidal poisoning before and after social economic stress, and to suggest the direction for the proper management. Methods: We reviewed medical records of 547 patients of suicide by poisoning who visited the emergency medical centers of St. Mary's hospitals from 1997 to 2004. For the annual trends analysis, we analyzed the demographic and toxicologic data of these patients compared with before and after IMF crisis (1998) and the economic recession ($2003\~2004$). Results: At the time of IMF and the economic recession, the number of suicidal poisoning increased, especially in fifth decade. The refusal rate of toxicological emergency treatment increased. Also the mortality rate and the admission rate to ICU (Intensive Care Unit) increased during the same period. In the result of the comparison analysis, clinical severity and mortality of social problem group were higher. However they couldn't be treated appropriately because of financial problem and the family indifference. Conclusion: At the economic recession period, the severity of suicidal poisoned patients was high. But the refusal rate of toxicologic treatment also increased, so the patients had lost the chance for proper toxicologic treatment. Therefore they would be supported by medical institution and public health.

Purpose: This study sought to identify factors associated with dental hygienists' decisions to leave one dental office and commence practice in another. In addition to, the reasons dental hygienists stay in the profession were investigated. Demographic descriptors, including education level, marital status and age, and employment setting were also examined. Methods: Currently practicing dental hygienists in Korea were surveyed from March to May 2003. Data were collected through a questionnaire. The survey collected information concerning the 461 respondents' personal characteristics and reasons associated with changing positions and staying. Data were analyzed using frequency distributions, independent t-tests and chi-square analyses. All statistical analyses were conducted using the Statistical Package for Social Scientists(SPSS v.10, Chicago, Illinois). Results: The primary reasons for taking up another employment were found to be better offer, inadequate salary and personal conflict with dentist. Secondary reasons stated for changing their job revealed additional factors including inadequate salary, better offer, and lack of benefits. The primary influence in deciding to remaining in the practice of dental hygiene was self-development. Family responsibility, safe environment and professional collaboration were also important factors in deciding to remain in workforce. Conclusion: The position changes of dental hygienists are primarily influenced by better offer. Inadequate salary and conflict with dentist were also important factors in deciding to change employment positions. The findings suggest that dental hygienists who remain in the workforce are positively influenced mainly by self-development. Employers of dental hygienists should be aware of these factors in employing process. If more hygienists could remain longer in their positions, the manpower situation would be affected positively.
