Purpose: It is to survey old men's utilization status of dental clinic and temporary-binding dentures and then to provide basic data to make a program for manufacturing old men's dentures and their teeth health education. Methods: Random selection was made on old men living in Daejeon and Chungnam, and a survey was conducted from April 15 to May 20, 2011. 500 questionnaires were distributed and 420 questionnaires were collected. Using spss 18.0 program, final analysis was made on 363 questionnaires except for 57 questionnaires which had missing value or showed some doubts about the unreliability. Results: 1. With respect to number of natural teeth as per the age, the upper/lower jaws had meaningful differences (P<.001), which means that the older the person is, the smaller number of natural teeth is. In the meantime, there was no meaningful difference according to sex. 2. With respect to kind of prosthetics installed in a mouth as per the age, there was meaningful difference in the upper jaws (P<.05) but there was no meaningful difference in the lower jaws. It was found out that the older the persons are, the more they use removable dentures while the younger the persons are, the more they use fixed partial dentures. 3. With respect to mouth health condition recognized by oneself, it showed bad (44.4%) and good (10.3%),which means recognition as bad is greater, and the age when prosthetics were first used is dispersed variously from below 40 to over 70. 4. Dental care institutions which they mainly used are hospital and clinics (91.5%), and 66.4% of them visited dental clinics lately. Preferential treatment if they go to dentists is as follows in the order of prosthetics (33.9%), gum treatment (24.2%) and pain treatment (14.9%). 5. 68.4% of them revisited dentists after installation of dentures and the reason for revisit is as follows in the order of poorly fitted dentures (35.1%), painful gum 25.9%, regular check-up 25.4% and difficult chewing 9.6%. Conclusion: As our country enters into an aging society, mouth health problem of old men has come to a serious issue, and therefore, a survey was conducted on some old men with respect to their utilization status of dental clinic and removable dentures in order to provide basic data for improvement of quality of their life, maintenance and enhancement of their mouth health. The study result shows that the older they are, the higher the loss rate of teeth as well as needs for prosthetics are, and thus it is thought the study will help to develop mouth health education program which may improve quality of old men's life by recovery of mouth functions declined due to loss of teeth and by regular check-up, education for mouth health control and following-up control of dentures.

The purpose of this study was to determine the association of some adult dental fear and depression, and stress. Among the patients who came to the dental clinic for periodontal treatment, 68 patients who agreed to participate in the study and who met the selection criteria were included. Dental fear, depression symptom questionnaire, salivary cortisol, which can objectively evaluate blood pressure, pulse, and stress. The results of the analysis showed that depressive symptom was related to 'delayed treatment promise', 'cancellation of treatment appointment', 'increased muscle tension', 'rapid breathing when entering dentistry', 'fear when waiting in the waiting room', 'fear when you smell the hospital', 'fear when looking at the dental clinic', 'fear when seeing the anesthetic needle', 'fear when tooth whistle was heard', 'fear when teeth were removed', and 'total fear of dentistry'(p<0.05). Stress symptoms were higher in 'having sweated in the dentist', 'faster pulse', 'fear of entering the dentist' and 'total fear of the dentist'(p<0.05). Based on these results, it is necessary to study the effective methods to control the depressive symptoms and stress of patients who visit dental clinics, and it seems that continuous management is needed to prepare methods such as relaxation therapy for dental fear patients.

This study estimated productivity change and RTS using Parametric and Non-Parametric approach with 5 year annual data from 2006 to 2010 of 20 public general hospitals in Vietnam collected from Ho Chi Min City Health Department of Health Database. The results could be summarized as follows; First, by the Non-Parametric approach. cumulated productivity growth of 5 years was increased by 2.8% due to regress 5.2% of technical efficiency, 0.3% of pure technical efficiency, but scale efficiency was decreased 5.1% Second, by the Non-Parametric approach, cumulated productivity growth was decreased by 12.8% to due to drop of 17.1% of technical change, 9.1% of scale efficiency. In conclusion, the common result of both approaches was that scale inefficiencies occurs in public hospitals in Vietnam, and they affected productivity change of public hospitals in Vietnam. Namely, 70% to 80% of the analyzed Vietnam public hospitals were at the status of DRS(decreased returns to scale), which suggested that they had oversupply beds relative to the number of occupied patients, it was meaningful that this study was the first study in Korea to measure efficiency and productivity change of Vietnamese public general hospitals and so it could be utilized as the basic information needed to enter hospital industry of Vietnam in the future.

Purpose: The rate of fistulas occuring followed by resection of oral cavity, oropharyngeal, hypopharyngeal, and laryngeal cancer are reported to be 9 ~ 23% according to various documents. Neglected treatment of the fistula can result in a setback in proper treatment with restrictions in oral intake leading to delayed return to daily life. Furthurmore, in severe cases, it may injure important vessels and adjacent structures of the neck area. The author reviewed previously reported cases of treatment methods for fistulas recurring after diverse head and neck operations and with sharing the treatment experiments of our patients, we tried to present a treatment algorism for different fistula types. Methods: Our study was based on retrograde analysis of 64 patients who were clinically diagnosed with fistula after operation for cancer of the head and neck from 1997 to 2008 at Severance Hospital. Their primary sites of cancer were 8 oral cavity, 22 oropharynx, 25 hypopharynx, and 9 larynx. The patients were aged 45 to 75 years and the male to female ratio was 11 to 1. The patient's operation records and progress notes were evaluated for determination of degree of fistula and treatment methods. Results: Most fistulas were clinically suspected after postoperative 5 days and symptoms noted for detection of the fistula were erythema, purulent discharge, edema, tenderness, and fluctuation. The fistula was definitely diagnosed at postoperative 2 weeks with barium test and treatment method ranging from conservative management to operative procedure were applied to each patients. Total 21 patients were managed with conservative protocol. In 15 cases, direct repair of the fistula was done and more stable repair of the fistula was possible with using of TachoComb$^{(R)}$. Pharyngostoma was performed in 14 patients. Among them, 4 patients healed spontaneously, 5 patients were taken direct closure, 4 patients were taken pectoralis major musculocutaneous flap, and one patient was taken esophageal transfer. The other 14 patients were taken 11 pectoralis major musculocutaneous flaps and 3 free flaps without pharyngostoma formation. Conclusion: Fistula is a troublesome complication resulting after resection of head and neck cancer. Early detection and adequate treatment according to the period and condition of the fistula may prevent further complications and reduce the pain of the patient.

Purpose: In this study, the clinical and epidemiological characteristics of patients admitted for viral croup were analyzed to evaluate disease severity based on the organism that caused the infection. Methods: We retrospectively reviewed the medical records of 302 patients who were admitted to the Department of Pediatrics at the Wonju Severance Hospital between May 2013 and December 2016 for viral croup. Patients who showed positive results on multiplex polymerase chain reaction were subsequently diagnosed with respiratory virus infection. The Westley scoring system was used to evaluate the severity of viral croup. Results: Of the 302 patients, 149 were admitted due to severe viral croup, including 88 boys and 61 girls, with a boy-to-girl ratio of 1.44:1. About 110 cases of parainfluenza virus infection have been reported, which accounted for almost half of the total cases. The other identified viruses included influenza virus, human rhinovirus, and respiratory syncytial virus. Analysis of the association between severe viral croup and causative pathogen revealed that only parainfluenza type 2 virus showed a significantly high risk. Parainfluenza type 2 virus did not show an age-based difference in frequency but showed relatively a higher frequency of infections during the summer and fall. Conclusions: In this study, parainfluenza virus type 2 was the only virus associated with severe viral croup. To facilitate proper preventive management, treatment, and prognosis evaluation of viral croup, prospective and multicenter studies should assess the additional variables and the severity of the virus. Additionally, further studies should be conducted to assess age-dependent influences, as well as the regional and seasonal incidence of viral infection.

Hypophayngeal cancers are usually diagnosed in advanced stages and in many cases, they need total pharyngocervical esophagectomy and surgical reconstruction. Among many surgical reconstructive methods, jejunal free flap has anatomical and functional advantages such as tubed nature, peristaltic activity, excellent blood supply. In this study we analysed the surgical procedure and complications of jejunal free flap after total pharyngo-cervical esophagectomy. 20 cases performed jejunal free flap from 1995 to 2007 at Severance Hospital were reviewed. According to time of onset, early and late complications were reviewed. Surgical procedure was reviewed with operation record. Oral diet tolerance was reviewed on the basis of pharyngogram and subjective symptoms. The most common complication was stricture, and it occurred in 40% of cases and 63% of them were managed with conservative care. As early complication, fistula formation was all managed with conservative care. Oral feeding tolerance after jejunal free flap was 65% and 7 patients were tolerable to general diet. In our study, stricture was the most common complication and its management is important in post op oral diet tolerance.

This study examined sexual violence characteristics among the individuals who utilized victim support services provided by National Rape Crisis Intervention Centers in Korea. The study is the part of a Korean longitudinal study on sexual assault characteristics and its implications for post-abuse adjustments, which is supported by Korean Mental Health Technology R&D Project. Eleven national rape crisis centers nationwide and 29 NGO's participated in the study. The participating centers provided the data on sexual abuse characteristics from their standardized case management system. The cases were randomly selected from the system. Total of 1077 cases were gleaned from the system and utilized for this analysis. Results indicated that the abuse characteristics differed by victims' age (children, adolescent vs. adults) as well as relationship with perpetrator. We could identify six different profile groups based on the detailed violence characteristics. The results assured us of the importance to understand the detailed characteristics of sexual violence and the old notion that 'one size may not fit all'. The results from the profile analyses may have important implication for developing victim support programs and appropriately allocating agency resources according to the different profiles of the service users.

Objectives: The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas. Methods: The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants' frailty. Results: The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy. Conclusions: More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.

The purpose of this study was to investigate the effect of helplessness, depression, subjective health status, family support, and social support on health promoting behaviors of elderly people over 65 years old. The subjects of this study were 3 welfare centers in G city and C city, 3 senior citizen center and 225 elderly people in 2 geriatric hospital, and this study was analyzed with descriptive statistics, reliability, correlation, confirmatory factor analysis, fitness test, total effect, direct effect, and indirect effect. The direct effects of variables affecting health promoting behaviors were social support, depression, family support, subjective health status, and helplessness. These variables accounted for 66% of health promoting behaviors. Depression, helplessness had a significant indirect effect on family support and social support, and subjective health status had a significant indirect effect on social support, but didn't have a significant indirect effect on family support. In this paper, we propose a new approach to elderly's health promoting behaviors and it is recommended that an intervention program be developed and applied to on personal situation should be necessary for elder's depression, helplessness and subjective health status.
