Background: The incidence of breast cancer is rising in Oman, and the disease is diagnosed at late stages, when treatment success is limited. Omani women might benefit from better awareness, so that breast cancer can be detected early and treated. This study was conducted to assess Omani women's levels of breast cancer awareness and early detection practice, and explore factors which might influence these levels. Materials and Methods: A mixed methods study was conducted in 2014, including a quantitative survey of 1,372 and a qualitative assessment of 19 Omani women, aged ${\geq}20years$ from five Omani governorates using convenient sampling. Demographic information and scores for awareness levels were used in a multivariate regression model to investigate factors associated with awareness. Thematic analysis and interpretive description were used to analyse the qualitative data. Results: The overall means for early detection and general awareness scores were 0.58 (SD 0.24) and 0.46 (SD 0.21), respectively. General awareness was significantly associated with age, education, income and familiarity with cancer patients (p<0.05), while early detection was significantly associated with age, marital status and education. A majority of women (59.5%) agreed with a belief in 'evil eye' or envy as a risk factor for breast cancer. Women discussed various factors which may empower or inhibit awareness, including the cultural-religion-fatalistic system, personal-familial-environmental system, and healthcare-political-social system. Conclusions: The overall low scores for awareness and early detection, and the survey of local beliefs highlight a severe necessity for a contextually-tailored breast cancer awareness intervention programme in Oman.

Background: Breast cancer is the most common cancer among women and leading cause of death worldwide, including in Turkey. High perceptions of cancer fatalism are associated with lower rates of participation in screening for breast cancer. This study was conducted to evaluate the effect of breast cancer fatalism and other factors on breast cancer awareness among nursing students in Turkey. Materials and Methods: This cross-sectional descriptive study was conducted at three universities in the Western Black Sea region. The sample was composed of 838 nursing students. Data were collected by Personal Information Form, Powe Fatalism Inventory (PFI) and Champion's Health Belief Model Scale (CHBMS). Results: Breast cancer fatalism perception of the students was at a low level. It was determined that students; seriousness perception was moderate, health motivation, BSE benefits and BSE self-efficacy perceptions were high, and BSE barriers and sensitivity perceptions were low. In addition, it was determined that students awareness of breast cancer was affected by breast cancer fatalism, class level, family history of breast cancer, knowledge on BSE, source of information on BSE, frequency of BSE performing, having breast examination by a healthcare professional within the last year and their health beliefs. Conclusions: In promoting breast cancer early diagnosis behaviour, it is recommended to evaluate fatalism perceptions and health beliefs of the students and to arrange training programs for this purpose.

Objectives : To analyze medical expenses by cancer site and survival time among cancer patients in their last year of life. Method : The study subjects were 45,394 people that had died of cancers in 2002, were registered by the Korea Central Cancer Registry and received National Health Insurance benefit in the last year (360 days) of life. Personal identification data, general characteristics, dates of death and cancer incidence, and site of cancer were collected from the National Statistical Office and the Korea Central Cancer Registry, and merged with the data of the individual medical expenses of the Health Insurance Review Agency. Results : Average monthly cost curves were U-shaped with high costs near the time of diagnosis and death, and lower costs in between. Medical expenses in the last year of life were around 30.3, 16.7, 13.0, and 12.1 million won among leukemia, lymphoma, ovarian cancer, and breast cancer patients, respectively. Digestive organ cancers including stomach, esophagus, liver, pancreas, and colorectal cancers had relatively low medical expenses. Medical expenses in the last year of life were inverse U-shaped with high expenses near one year of survival. Average monthly cost in the 12 months before death among the patients who had survived $10{\sim}15$ years were more than two-fold greater than the cost before diagnosis among those who had survived for less than one year. Conclusions : Leukemia was the most expensive cancer. It is possible that once diagnosed as cancer, medical expenses do not return to the level before diagnosis. Further research will be needed to understand the magnitude and change of the medical expenses among cancer patients with long term follow up data.

Access to health care is complicated to define. It is a multidimensional process. In addition to the matters of quality of care, geographical accessibility and availability of the right type of care, finance, and acceptability are all involved. The purposes of this paper are to measure the geographic distances between patient residency locations and health service organizations in which the patients hadvisited, and to investigate the association between geographical distance measures and variables involved in health service utilization. The study used the first and the second wave of the 2008 Korea Health Panel Survey. The samples of analyses were patients who had visited outpatient or used ambulatory health services, and the total observations (visit numbers) analyzed were 229,128. We divided the samples into a frequent-visit illness group (Group 1) and a non-frequent visit illness group (Group 2) based on over 5,000 total visit numbers. We exploited three level analyses using xtmixed of STATA${\Box}$ 11.1 command with/without interaction terms among age, sex, and occupation. Geographical distances were measured using the Haversine method. Group 1 was tended to older and lower equivalent income than those of Group 2, but the geographic difference were not observed in terms of area deprivation index and standard mortality ratios. Amongst group 1, diabetes mellitus patients travelled far to visit health care organizations, and arthritis patients were more deprived in terms of the personal and areal characteristics. The study revealed that residents in rural areas traveled about 10 times more long distances than those whom lived in larger cities after adjusting for various variables, which we used for analyses. This study contributed to the practical understanding of health service utilizations using empirical analyses, and found that the types of diseases and socioeconomic characteristics of patients tended to define the amount of travel distance to healthcare organizations.

Wearable Device를 사용하는 WBAN 환경에서는 다수의 신체 부착형 센서와 이들의 데이터를 수집하는 장치로 구분할 수 있다. 일반적으로 신체에 부착되는 센서는 소형화와 경량화를 목적으로 매우 낮은 에너지 자원을 보유하지만, 사용자 단말기 등을 활용하는 데이터 수집 장치는 재충전이 가능하며 신체 부착형 센서에 비하여 높은 에너지를 가진다. 본 논문은 이러한 환경적 특성을 고려하여 센서의 수명을 늘리고 불가피한 에너지 소모를 수집 장치에 집중시키는 MAC 프로토콜을 제안한다. 또한 제안 프로토콜은 응급 데이터의 보고체계가 사용되는 응용환경을 고려하여, 일반적인 센싱 데이터와 응급 데이터를 구분하고 차별화된 전송 지연시간을 제공한다. 또한 제안하는 MAC 프로토콜의 효율적인 성능검증을 위하여 IEEE 802.15.6과 비교실험을 통하여 제안방식의 이득을 검증하고 이를 분석한다.

This study was conducted to assess needs of self-management nutrition program for diabetic patients. The survey was conducted among 100 diabetic patients, and the mean age of the subjects was 54.2 years old. Thirty three percent of the subjects were diagnosed diabetes less than 2 years ago. The average nutrition knowledge score about diabetes was 10.2 point, and percentages of correct answers were very high in 'foods rich in fiber' (97.0%), 'relevance of exercise and insulin' (97.0%), 'quantity of insulin injection' (91.0%), and 'diabetes menu' (91.0%). The sources of nutrition information were hospitals/healthcare centers (56.1%), TV/radio (19.2%), and internet (13.1%). Sixty nine percent of the subjects have experienced nutrition education on subjects as 'menu planning skills'(22.4%), 'selecting foods' (22.4%), 'relevance of blood glucose and eating foods' (21.5%) by personal counseling (54.4%). The total score of eating behavior was higher after diagnosed diabetes (35.3) than before (30.0) (p < 0.001). The preferred topics in developing diabetes nutrition information websites were 'diabetes mellitus', 'relevance of blood glucose and foods', and 'selecting foods for diabetes'. The subjects wanted the websites developed by 'using mainly illustrations, pictures, tables' (22.8%) and 'using simple design' (19.6%). The preferred contents in developing diabetes self-management nutrition program were 'dietary life diagnosis', 'chronic disease risk diagnosis', 'calorie control by selecting foods and cooking skills', and 'dietary assessment'. In designing the program, the subjects' most wanted designs were 'be handy and simple in using' (29.3%), 'using simple design' (17.9%), and 'using mainly illustrations, pictures, tables' (15.7%).

최근 무선 인체 네트워크 (WBAN)는 유비쿼터스 헬스케어 시스템에의 활용으로 주목 받고 있다. WBAN에서는 인체에 부착 되거나 이식되는 센서 노드와 PDA와 같은 휴대용 개인 베이스 스테이션 (BS)의 에너지 제약이 있고, 이 장치들의 제한된 계산 능력과 메모리 때문에 노드들이 수행하는 계산의 복잡도를 최대한 줄여야만 한다. 또한 생체 신호를 다루기 때문에 신뢰성 있는 데이터 전송이 필수적이다. 본 논문에서는 네트워크 코딩 오버헤드를 줄이고 에너지 효율을 높이기 위해 WBAN을 위한 시스테매틱 (systematic) 네트워크 코딩 기법을 제안한다. 제안하는 시스템을 마코프 체인 (Markov chain)을 이용해 모델링 하고 모든 노드가 BS로의 데이터 패킷 전송을 완료하는데 까지 소모되는 에너지를 최소화 하는 것을 최적화 문제로 정의 하였다. 다양한 환경에서 시뮬레이션을 수행 한 결과 기존의 전송 방법과 비교 했을 때 에너지 효율을 얻는 것을 보였다. 또한 기존의 WBAN에서의 네트워크 코딩의 디코딩 과정 보다 계산 복잡도가 낮아 네트워크 코딩으로 인한 계산 오버헤드를 줄였다.
