Background Laryngeal allotransplantation (LA) is a technique involving transplantation of a deceased donor's larynx into a recipient, and it may be substituted for conventional laryngeal reconstruction. There are widely different views on LA, as the recipient is administered continuous, potentially life-threatening, immunosuppressive therapy for a functional or aesthetic result, which is not directly related to life extension. The purpose of this study was to analyze the difference in risk acceptance and expectations of LA between four population groups. Methods A survey was performed to examine patients' risk acceptance and expectations of LA. The survey included 287 subjects in total (general public, n=100; kidney transplant recipients, n=53; post-laryngectomy patients, n=34; doctors, n=100), using a Korean translated version of the louisville instrument for transplantation (LIFT) questionnaire. Results All four groups responded differently at various levels of their perception in risk acceptance and expectations. The kidney transplant recipients reported the highest risk acceptance and expectations, and the doctor group the lowest. Conclusions This study examined the disparate perception between specific population groups of the risks and benefits of using LA for the promotion of the quality of life. By addressing the information gaps about LA in the different populations that have been highlighted from this survey, we suggest that LA can become a more viable alternative to classical surgery with resultant improved quality of life for patients.

Allergic contact or wound induced dermatitis are common environmental health issue and seriously affect the patient's quality of life. In now, people are interested in the korean herbal bathing that get better the skin conditions. This study was performed to investigate the effect of korean herbal bathing candidates extract on allergic contact or wound induced dermatitis. ICR mice were divided into four groups: naive, control, experimental group A and B. Control and experimental groups induced allergic contact or wound induced dermatitis by DNFB and TMA. Since then, each experimental group was pasted with corresponding korean herbal bathing extract into the skin. All groups were observed after 5 days. When the korean herbal bathing extract was applied, arbitrary skin wound index and epidermal thickness were significantly decreased compared to that of control. These data suggest that these korean herbal bathing candidates may be an effective therapeutic supplements for the treatment of skin.

The purpose of this study is to measure and evaluate radiation dose on patients in interventional radiological(IVR) procedures classified by each procedure, and aid as data for safety management. Fluroscopy time(F-time), dose area product(DAP) and number of acquired images from each kind of procedure was checked. Non-vascular procedures showed low value, and vascular procedure showed high value in all procedures except in IVC filter. F-time was longest in EVAR, which showed also the highest DAP value of all procedures. DAP-rate showed high value in TACE. By this result, we attempt to establish standard guideline of radiation dose on patients in IVR procedure.

The emerging of ubiquitous computing and healthcare technologies provides us a strong platform to build sustainable healthcare applications especially those that require real-time information related to personal healthcare regardless of place. We realize that system stability, reliability and data protection are also important requirements for u-healthcare services. Therefore, in this paper, we designed a u-healthcare system which can be attached to the patient's body to measure vital signals, enhanced with USN secure sensor module. Our proposed u-healthcare system is using wireless sensor modules embedded with NLM-128 algorithm. In addition, PS-LFSR technique is applied to the NLM-128 algorithm to enable faster and more efficient computation. We included some performance statistical results in term of CPU cycles spent on NLM-128 algorithm with and without the PS-LFSR optimization for performance evaluation.

Objectives: The purpose of the study is to investigate the influence of community oral hygiene program on oral hygiene practice behavior in children. Methods: Oral hygiene promotion program was performed in 23 community child centers in Seoul, Incheon and Gyeonggido. The study analyzed the effect of community oral hygiene promotion programs on the oral hygiene practice behavior in children from September to December, 2014. The trained dental hygienists in 23 public health centers and dental hygiene students participated in the oral hygiene promotion program for oral health examination and education for the children. The contents of the program was standardized and instructed to the team members. The individual improvement in children oral hygiene practice was assessed using PHP(patient hygiene performance) index score. Data were analyzed using SPSS 12.0 program. Results: After the program, children who stopped eating confectioneries and those eating once a day increased to 32.12% and 14.24%, respectively. Those eating more than four times a day were still high(32.44%), but it was a lower rate than before the program (p<0.001). The rate of toothbrushing of more than 2 to 3 times a day was 82.75% and it was higher than before the education (p<0.001). The knowledge level of children increased from 18.83% to 66.30%. The oral hygiene practice performance in children was highly improved. Conclusions: The four months duration of oral hygiene program remarkably improved the oral hygiene practice in the children. So the community health centers and welfare centers must cooperate and improve the children oral health promotion by developing the oral health promotion program.

Nearly 20 years after the Boramea Hospital case, the act on decisions on life-sustaining treatment for patients in hospice and palliative care or at the end of life has taken effect on February 4, 2018 as recommended by the National Bioethics Committee. However, during the legislation process, some parts of the bill that stakeholders and concerned parties did not see eye to eye were either revised or removed. Moreover, the hospice and palliative care part was added in the last minute before the enactment. As a result, the law includes parts that are not in line with the recommendations from the National Bioethics Committee, thereby causing various problems. Therefore, it is crucial to monitor how the decisions on life-sustaining treatments are made in the field and gather various opinions of concerned parties to identify and address problems in the early stage of the implementation of the law. Based on the data, the legislation must be amended to fulfill its purpose that is "to protect the dignity and value of human beings by assuring the best interests of the patients and by respecting their self-determination".

Purpose: The present study was designed to identify cancer patients' needs when chemotherapy ends. Method: In-depth interview with focus questions was applied for the study. The participants were recruited from the patients receiving cancer chemotherapy in a university hospital. They were seven cancer patients with stomach cancer and two with liver cancer at the ending period of their chemotherapy protocol. Participants were interviewed on discharge date of last treatment and when they returned for the first outpatient follow-up. The focus question was 'what are your needs at this point?' The interviews were audio-taped and transcribed before analysis. The data were analyzed for common categories, special analytic categories, and conceptual categories. Results: Thirty two common categories, ten special analytic categories, and six conceptual categories were identified as patient's needs. The six conceptual categories were comfort needs, social needs, information needs, humanism needs, environmental needs, and self-efficacy needs. Conclusion: There were characteristic specific patients' needs when chemotherapy ends. There are needs to develop and to apply nursing intervention for cancer patients.

Objectives: The inactivation of the tumor suppressor gene $p16^{INK4a}$ plays an important role in the development of malignant tumors, including oral squamous cell carcinoma. The p16 gene is involved in the p16/cyclin-dependent kinase/retinoblastoma (Rb) gene pathway of cell cycle control. The p16 protein is considered a negative regulator of this pathway. The p16 gene encodes an inhibitor of cyclin-dependent kinases 4 and 6 which regulate the phosphorylation of the retinoblastoma gene and G1 to S phase transition in the cell cycle. However, the p16 gene can lose its functionality through point mutations, loss of heterozygosity or methylation of its promoter region. Materials and Methods: In this study, the authors analyzed the correlation between various clinicopathological findings- patient age, gender and smoking, disease recurrence, tumor size, stage, and differentiation- and p16 protein expression or p16 promoter hypermethylation in 59 cases of head and neck squamous cell carcinoma. Results: The results revealed p16 protein expression and p16 promoter hypermethylation in 28 cases (47.5%) and 21 cases (35.6%), respectively, of head and neck squamous cell carcinoma. However, neither p16 protein expression nor p16 promoter hypermethylation had any statistical influence on clinicopathological findings or survival rate. Conclusion: This data, and a review of the literature, suggest that p16 promoter hypermethylation cannot yet be used as an independent prognostic factor influencing carcinogenesis, but must be considered as an important factor along with other genetic alterations affecting the pRb pathway.

Purpose: This study was designed to investigate the present conditions of illumination techniques in dental clinics in order to contribute improvement of operating environment. This study also aimed exploring qualitative and quantitative luminous intensity required for color temperature in dental clinic illumination, which was a critical part of esthetic dentistry. Materials and methods: A total of forty-eight local dental clinics were selected for sampling a) luminous intensity, and b) color temperature. The author measured the luminous intensity and the color temperature with lux meter and color meter respectively between 12pm and 2pm. The dental unit chair placed in the general operation positions were kept the distance 60 cm then all dental units were measured three times and averaged. The author measured the luminous intensity and color temperature with both common dental operating light and then without operating light in different office environments. The study was conducted under three conditions: 1 artificial illumination in clear day light 2. artificial illumination in cloudy day light, and 3. artificial illumination alone. Results : The results obtained were as follows. 1. The average luminous intensity in dental clinic lighting was 425 lux which was not sufficient to produce the optimal shade of the patient's teeth. Furthermore, the average luminous intensity even in full operating lighting was 9532 lux which fell short of the required level of 10,000 lux. 2. The average color temperature of all dental clinics surveyed was 5169 K which met the optimal range. However, only 33.3% fell in the correct region between 5,000-5,500 K as 25% were over 5,500 K and 41.6% were below 5,000 K. As a result, 66.7% were under insufficient color temperature conditions. 3. The dental unit chair placed next to a window, hence exposure to natural lighting, had significantly higher luminous intensity and color temperature compared to the dental unit chair which didn't have a window or natural lighting. 4. The data analysis revealed that only 6.3% of the dental clinic were met the standard of the average luminous intensity and color temperature.

Purpose: This study was conducted to analyze factors affecting readmission of children with home ventilator care. Methods: To collect patient data, a retrospective chart review was done of medical records of children admitted between June 1, 2007 and May 31, 2010 at one children's hospital located in Seoul. During that period 30 children were discharged with a home ventilator. Results: Twenty-one of these children had a total of 63 readmissions during the study period, averaging 2.1 readmissions per child with a mean duration of hospitalization of 7.4 days. Children with nasogastric tubes were more frequently readmitted (t=7.232, p=.012) and duration of hospitalization was significantly longer (t=4.761, p=.038). Children who had cardio-pulmonary comorbidity were more frequently readmitted and had longer hospitalization than children without comorbidity (t=5.444, p=.027). When home ventilator assisted children were admitted via emergency room, they were hospitalized longer (t=14.686, p=<.001). Cardio-pulmonary morbidity and readmission via ER explained 38.1% of variation for readmission. Feeding method explained 15.0% of variation in length of hospitalization. Conclusion: The results suggest that health care providers must give individualized education on home ventilator care to parents with children who are at risk for readmission due to cardio-pulmonary comorbidities, nasogastric tube, or readmission via ER.
