The trend in modern nursing is toward the performance of comprehensive nursing care. Psychiatric nursing emphasizes education which enables the nurse to understand the underlying difficulties being expressed through a wide range of emotions and through practice to be more adept in her selection of a manner of approach which best meets the needs of a given situation. Presently, in Korea, there is nothing in the literature regarding evaluation of the effect of psychiatric nursing education on the attitudes of nurses towards mental illness and mentally ill patients. This stud!1 was attempted in order to understand 1) some of the problems in psychiatric nursing education 2) some of tile factors which affect the attitudes of nurses towards mental illness and mental patients. A questionnaire, a Korean translation of the "Opinions about Mental illness Scale" by Cohen and Stranding, 1962, was administered to 188 nonpsychiatric registered nurses employed in Yonsei University Hospital (Y. Hospital) and Seoul National University Hospital (S. Hospital) located in the city of Seoul. All of the nurses were directly involved with adult patient care. They graduated from various nursing schools. The data was collected during the period of October 2 to October 16,1972. The age, educational background , marital status, type of previous psychiatric experience, experience as a graduate nurse and close personal relationship with someone who was a psychiatric patient were compared with the O.M.I. scores. The mean and standard errors for each of the comparison groups were computed and tile relationships calculated by a t-test. The results of the study are summarized as follow: 1. There is no significant difference between the age of the nurses and their attitudes toward mental illness and mental patients. 2. There is no significant difference between the. educational backgrounds of the nurses and their attitudes toward mental illness and mental patients. 3. There is a significant difference in the nurses ′student psychiatric nursing experience and their attitudes towards mental illness and mental patients for the nurses in 5. Hospital only. The nurses who had 3-4 week of student psychiatric nursing experience had a significantly higher mean score for Benevolence (factor B) than nurses whose student psychiatric experience had been less than 1 Ivcek (P<0.05). The nurses who had 1-2 weeks, 3-4 weeks and more than 4 weeks of student psychiatric nursing experience had significantly higher mean scores for Interpersonal Ethology (factor E) than nurses whose student psychiatric had been less than 1 week (p<0.05), 4. There is a significant difference in the nurses′student psychiatric nursing experience by types of institution and their attitudes towards mental illness and mental patients for S. Hospital nurses only. The nurses who had their student psychiatric nursing experience in the government psychiatric hospitals recorded significantly higher mean score for Authoritarianism (factor A) than nurses who had their. experience in private psychiatric hospitals (p<0.05). 5. There is no significant difference in the nurses′psychiatric nursing experience as a graduate nurse and their attitudes toward mental illness and mental patients. 6. There is no significant difference in the nature and variety of the nurses′experience as a graduate nurse and their attitude toward mental illness and mental patients. 7. There is no significant difference in the presence or absence of a close personal relationship with a mentally ill person and the nurses′attitude toward mental illness and mental patients. 8. There is no significant difference in the nurses′ marital status and their attitude toward mental illness and mental patients. 9. There is no significant difference between the nurses who were employed ill S. and Y. hospitals and their attitudes towards mental illness and mental patients. Major suggestion for further study was to have more larger and wider scale research for establishing of the reliability and validity of the Korean translation of the O.H.I. Scale.

With advancements in technology of virtual reality, it is used for various purposes in many fields such as medical care and healthcare, but as the same time there are also increasing reports of nausea, eye fatigue, dizziness, and headache from users. These symptoms of motion sickness are referred to as cybersickness, and various researches are under way to solve the cybersickness problem because it can cause inconvenience to the user and cause adverse effects such as discomfort or stress. However, there is no official standard for the causes and solutions of cybersickness at present. This is also related to the absence of tools to quantitatively measure the cybersickness. In order to overcome these limitations, this study proposed quantitative and objective cybersickness evaluation method. We measured 128-channel EEG waves from ten participants experiencing visually stimulated virtual reality. We calculated the relative power of delta and alpha in 11 regions (left, middle, right frontal, parietal, occipital and left, right temporal lobe). Multiple regression models were obtained in a stepwise manner with the motion sickness susceptibility questionnaire (MSSQ) scores indicating the susceptibility of the subject to the motion sickness. A multiple regression model with the highest under the area ROC curve (AUC) was derived. In the multiple regression model derived from this study, it was possible to distinguish cybersickness by accuracy of 95.1% with 11 explanatory variables (P_D.MF, P_D.LP, P_D.MP, P_D.RP, P_D.MO, P_A.LF, P_A.MF, P_A.RF, P_A.LP, P_A.RP, P_A.MO). In summary, in this study, objective response to cybersickness was confirmed through 128 channels of EEG. The analysis results showed that there was a clearly distinguished reaction at a specific part of the brain. Using the results and analytical methods of this study, it is expected that it will be useful for the future studies related to the cybersickness.

Background: The standard radiotherapy (RT) fractionation practiced in India and worldwide is 50Gy in 25 fractions over 5 weeks to the chest wall or whole breast followed by tumour bed boost in case of breast conservation (BCS). A body of validated data exists regarding hypofractionation in breast cancer. We here report initial results for 135 patients treated at our center with the START-B type of fractionation. Materials and Methods: From May 2011 till July 2012, women with all stages of breast cancer (excluding metastatic), who had undergone BCS or mastectomy were planned for 40Gy in 15 fractions over 3weeks to chest wall/whole breast and supraclavicular fossa (where indicated) followed by tumour bed boost in BCS patients. Planning was done using Casebow's technique. The primary end point was to assess the acute toxicity and the cosmetic outcomes. Using cosmetic scales; patients were assessed during radiotherapy and at subsequent follow up visits with the radiation oncologist. Results: Of the 135 patients, 62 had undergone BCS and 73 mastectomy. Median age of the population was 52 years. Some 80% were T1&T2 tumours in BCS whereas most patients in mastectomy group were T3&T4 tumours (60%). 45% were node negative in BCS group whilst it was 23% in the mastectomy group. Average NPI scores were 3.9 and 4.9, respectively. Most frequently reported histopathology report was infiltrating ductal carcinoma (87%), grade III being most common (58%), and 69% were ER positive tumours, and 30% were Her 2 Neu positive. Triple negative tumours accounted for 13% and their mean age was young (43 yrs.) The maximum acute skin toxicity at the end of treatment was Grade 1 in 94% of the mastectomy grouppatients and 71% in BCS patients. Grade 2 toxicity was 6% in mast group and 23% in BCS group. Grade 3 was 6% in BCS group, no grade 3 toxicity in mastectomy patients and there was no grade 4 skin toxicity in any case. Post RT at 1 month; 39% of BCS patients had persisting Grade I skin reaction which was only 2% in mastectomy patients. At 3 months post RT, 18% patients had persisting hyperpigmentation. At 6 months 8% patients had persisting erythema in the BCS group only. Some 3% BCS and 8% mastectomy patients had lymph edema till the date of evaluation. Cosmetic outcome in BCS patients remained good to excellent 6 months post surgery and radiotherapy. 1 patient of BCS and 3 patients of mast had developed metastatic disease at the time of evaluation. Conclusions: Hypofractionated RT is well tolerated in Indian population with reduced acute skin toxicity and good cosmetic outcome. Regimens such as these should be encouraged in other centers to increase machine output time. The study is on-going to assess long term results.

Background: Measurement of body temperature is an important parameter in patient management in many clinical conditions. Failure to reach minimal acceptable body temperature standards has been associated with physiological derangements and has necessitated the application of additional therapy. The authors developed a new, simple, accurate thermometry system, which could be used to undertake precise temperature measurement for various clinical conditions. Materials and Methods: A new thermometry system using a specially designed temperature detecting and display system was developed. This system contains a temperature detecting sensor(LM 35CZ), which enables multiple serial checking of heat, data collection and processing computer, and 3-dimensional display system. It provides real time volumetric visualization of temperature distribution of a defined volume and stores and prints the data. Results: With this system, temperature can be measured at multiple interesting sites simultaneously, demonstrated as a 3-dimensional temperature distribution and stored. In well-controlled, systematic experiments a significant correlation has been observed between standard temperature and temperature using this system at various measuring points. Conclusion: This thermometry system is a real-time measurement system, which can demonstrate 3-dimensional heat distribution in experimental phantom and human body and can be used for diagnosing abnormal clinical conditions. In addition, this system reduces the nursing staff work load, providing them more time for long term care to patients.

Background: Despite the decreased incidence, gastric cancer is still a frequent cause of cancer related death. The 1st line 2 or 3 drugs regimen is still a debatable issue. HER2 targeted therapy has emerged as the standard of care, but it is unavailable in the Brazilian Public Health System. The end-point of this trial was overall survival (OS) in patients with metastatic gastric cancer treated in a public university hospital in Brazil. The secondary end-points were efficacy and safety of regimens with 2 (F+P) or 3 (EOX) drugs to develop an institutional guideline to facilitate optimal treatments. Materials and Methods: In this retrospective study, 1st line regimens were evaluated for OS and PFS stratified by age and ECOG using Cox regression. Results: 47 patients were treated over the last 3 years. In 1st line, 29 were treated with F+P (mean 59.3 years, 34.5% ECOG 2 and a mean of 5.69 cycles) and 16 with EOX (mean 47 years, 18.8% ECOG 2 and a mean of 5.44 cycles). The median OS was 13.8 months (95%CI 10.7-16.9). Response was evaluated in 40 cases and was 64.3% for EOX and 37.5% for F+P (p=0.25). The median PFS was 9.5 months for EOX and 5.6 months for F+P (HR 0.85, 95%CI 0.41-1.74). However, among patients with ECOG 2 mPFS was 3.70 vs 5.40 months, respectively (p=0.86). Regimens showed similar manageable adverse events. A total of 34 patients suffered progression and 14 received $2^{nd}$ line therapy. Diffuse histology (HR 1.89, 95%CI 1.22-2.88), achieving 2nd line (HR: 0.25, 95%CI 0.11-0.58) and treatment response (HR 0.23, 95%CI 0.12-0.47) were OS prognostic factors. Conclusions: Patients treated in our hospital had outcomes compatible with the literature. The regimen choice should be related to patient features. Second line treatment should be considered.

In this study, the cartridge part of the focused ultrasound stimulation system was used as a sample to conduct a skin irritation test and a skin sensitization test through animal experiments among the tests related to GLP (Good Laboratory Practice), a medical device safety evaluation standard. The test was conducted after IACUC approval using 6 female New Zeland White Rabbits. The polar and non-polar stimulation indices were all '0.0'. In addition, in the case of skin sensitization evaluation, 30 guinea pigs approved by IACUC were divided into control and experimental groups, and all induction and induction steps were applied using the eluate itself without separate dilution of the test sample and blank test solution. As a result of the experiment, the skin reaction grade of the control animal was 0 grade, and there was no animal showing more than 1 grade in the skin reaction of the test animal. As a result of both tests, no abnormal skin symptoms were observed, and when applied to the human body to treat patients, the test materials used in the tests will investigate the stability of whether any diseases that cause skin abnormal symptoms will occur.

Purpose: The purpose of this study was to provide the basic information on the improvement plan by identifying the role accomplishment and job satisfaction of the hospice nurses and analyzing the factors that impact such role accomplishment and job satisfaction. Methods: The data was collected of 189 hospice nurses who have been working more than 6 months in 56 hospice programs registered in Korea Hospice Association and Korean Catholic Hospice Association from October to November, 2007 by structured questionnaire which was developed by Ryu(1979), based on the Riehl's nursing role and the research of Choe(2005) on the role of hospice nurse. Results: The role accomplishment and job satisfaction of the study subject were 3.53 point and 3.39 point, respectively. The roles of hospice nurses were accomplished by the order of advocator, nursing care provider, coordinator (cooperation), educator, quality manager, counsellor, administrator, and researcher. The job satisfaction of the hospice nurses was shown highest in the satisfaction of professional status, followed by the satisfaction of the interaction, satisfaction of the task itself, satisfaction of the administrative aspect, satisfaction of the autonomous, and the lowest in the satisfaction of the pay. The role accomplishment of the subjects according to their socio-demographic and job characteristics was found to have a significant difference by their age, marriage status, academic background, and position. It also has a significant difference by whether they play role of coordinator, whether they took whole responsibility as hospice, working experience as hospice/palliative nurse, and the level of hospice/palliative nursing training(p<.05). In the study of job satisfaction of the subjects according to their socio-demographic and job characteristics, the job satisfaction was found to have a significant difference by the increase of age, the number of duties consisting the hospice team, whether they play role of coordinator, whether they take whole responsibility as hospice, the level of hospice/palliative nursing training, and whether they wish to work for as long as possible(p<.05). The role accomplishment and the job satisfaction of the subjects showed a statistically significant positive correlation. (r=.541, p<.01) Conclusion: Raised saiary will be increased hospice nurse's job satisfaction. And we suggest a repetitive study using the identical tool to the equally extracted subjects with same representativeness of each hospice/palliative institute type. For the expanded role and enhanced professional standard of hospice nurses, we also suggest a study on the improvement plan to enhance the roles of researcher and administrator.

The present study aims to identify the ego, marriage and parenting-related psychological characteristics of mothers of infants with developmental risk, as well as to perform comparative analysis between their psychological characteristics and those of mothers of normal infants. For this purpose, we used SPSS 21 statistical software to calculate the average and standard deviation values, and also conducted frequency analysis and t-tests. The study subjects were mothers of 1584 normal infants and 186 infants with developmental risk, who were classified by Korean Denver II developmental screening test from a total of 1802 families listed in the 3rd year data from the Panel Study on Korean Children in 2010. Our results revealed a significant difference in the martial satisfaction and husbands' parenting participation between two groups, among the marriage-related psychological characteristics. There was also a significant difference in the parenting knowledge, style and stress among the parenting-related psychological characteristics. However, a statistically significant difference was not observed in the ego-related psychological characteristics of mothers. These results are thought to serve as baseline data for the infants with developmental risk at the precautionary level.
