Background: Solid cancers with bone marrow metastases are rare but lethal. This study aimed to identify clinical factors predictive of survival in adult patients with solid cancers and bone marrow metastases. Methods: A total of 83 patients were enrolled consecutively between January 1, 2000 and December 31, 2012. Bone marrow metastases were confirmed by biopsies. Patient clinical features and laboratory data were analyzed for associations. Results: The median age of the patients was 54 years (range, 23-88 years), and 58% were male. The 3 most common primary tumor locations were the stomach (32 patients, 39%), prostate (16 patients, 19%), and lungs (12 patients, 15%). The median overall survival was 49 days (range, 3-1423 days). Patients with Eastern Cooperative Oncology Group performance status 1, cancers of prostate origin, platelet counts over 50,000/ml, and undergoing antitumor therapies had a significantly better prognosis in the multivariate analysis. The median survival times were 173 and 33 days for patients with 2-3 more favorable parameters (n=24) and those with 0-1 (n=69), respectively (hazard ratio 0.30; 95% CI 0.17-0.52, p<0.001). Conclusions: Solid cancers with bone marrow metastases are dismal and incurable diseases. Understanding prognostic factors to these diseases helps medical personnel to provide appropriate treatments and better inform patients about outcomes. Antitumor therapies may improve outcomes in selected patient cohorts.

Recently, the problem of air pollution has become a global concern due to industrialization and overcrowding. Air pollution can cause various adverse effects on human health, among which respiratory diseases such as asthma, which have been of interest in this study, can be directly affected. Previous studies have used clinical data to identify how air pollutant affect diseases such as asthma based on relatively small samples. This is high likely to result in inconsistent results for each collection samples, and has significant limitations in that research is difficult for anyone other than the medical profession. In this study, the main focus was on predicting the actual asthmatic occurrence, based on data on the atmospheric environment data released by the government and the frequency of asthma outbreaks. First of all, this study verified the significant effects of each air pollutant with a time lag on the outbreak of asthma through the time-lag Pearson Correlation Coefficient. Second, train data built on the basis of verification results are utilized in Deep Learning algorithms, and models optimized for predicting the asthmatic occurrence are designed. The average error rate of the model was about 11.86%, indicating superior performance compared to other machine learning-based algorithms. The proposed model can be used for efficiency in the national insurance system and health budget management, and can also provide efficiency in the deployment and supply of medical personnel in hospitals. And it can also contribute to the promotion of national health through early warning of the risk of outbreak by atmospheric environment for chronic asthma patients.

The purpose of this study was to evaluate the difference in perception of clinical nutrition service (CNS) between doctors and dietitians working in hospitals in Busan and the Gyeongnam area. Research was performed through questionnaires (from November to December 2011) at over 100 beds. 73.3% of dietitians were aware of the Nutrition Support Team (NST), while only 15.6% of doctors were aware of it. Due to heavy work and lack of medical staff, doctors didn't participate in NST, although most of them recognized the necessity of NST. 61.7% of dietitians screened and managed malnourished patients, whereas only 29.8% of doctors did. The main reason dietitians didn't treat malnourished patients was the absence of a treatment system in the hospital. Less than 50% of dietitians participated in the doctor's round to malnourished patients. As for why dietitians didn't participate in doctor's rounds, 71% of doctors chose understaffed dietitians and 38.1% of dietitians chose the doctors' unawareness of the importance of the dietitian in doctor's rounds. For the lower rate of nutrition counseling in provincial regions, compared to the capital region, 46.8% of doctors cited a lack of connection between doctors and clinical dietitians, while 43.3% of dietitians cited the lack of doctors' awareness on the importance of nutrition counseling. Although 87.3% of the doctors and 91.6% of the dietitians answered that CNS is important for treatment, the perception of onsite performance status on CNS was found to be low in both groups. 48.9% of doctors and 50.0% of dietitians regarded dietitians in the hospital as personnel in charge of food services, rather a member of the medical team. To improve the awareness of the importance of the CNS, and the image of clinical dietitians, 31.2% of doctors answered "to introduce a professional dietitian license for each disease" and 26.7% of dietitians answered "to change the system in the hospital". Most subjects found that a separation of clinical nutrition services from the food service part is needed. These results suggest that it is important to narrow the difference in perceptions of clinical nutrition services between doctors and dietitians for an organized clinical nutrition management of patients in hospitals in Busan and the Gyeongnam area.

As medical practices and procedures become more specialized and information technology develops in clinical settings, health organizations need medical personnel with special skills, knowledge and competency. But the lack of practical experience in clinical settings may impair competency in basic nursing skills among nursing students. This study used a cross-sectional survey to analyze factors related to nursing competency among nursing students in order to establish effective teaching methods to increase the clinical competency of nursing students. The data were collected from a questionnaire distributed in several universities among 106 nursing students who expressed a willingness to participate in the study during December 2011 in order to measure self-directedness, professional self-concepts, communication ability, learning satisfaction. The data were analyzed using the SPSS window program. There were differences regarding competency in basic nursing skills according to interpersonal relationships, grades, existence of an open lab. The level of learning satisfaction, communication skills and self-directedness were deemed influencing factors regarding competency in basic nursing skills. These 3 elements account for 49.9% of competency with regard to basic nursing skills. According to existing research, blended learning methods which consist of problem based learning, cyber education or case centered education should be considered as effective teaching methods for developing clinical nursing skills.

Nursing home plays a role in providing elderly care in the context of China's rapid population aging, but little understanding of the efficiency of the nursing homes. In this paper, we investigated the efficiency in nursing homes using Data Envelopment Analysis (DEA) and Malmquist index (MPI) for the modeling of the number of nursing home beds, fixed assets, and medical personnel as input variables, and the number of elderly people of self-care, the number of elderly people of partial self-care, the number of bed-ridden elderly people and the income of nursing homes as output variables. Stratification analysis showed that the top two provinces in the DEA-CCR yield were Beijing and Shanghai in the five-year survey period. Four provinces (Beijing, Jiangsu, Shandong, and Shanghai) scored 1.00 in terms of DEA-BCC yield. The MPI analysis showed that Hainan ranked the highest five-year average in the included provinces. In terms of resource utilization, internal management, operation scale, and other aspects, the nursing homes in the provinces with high-efficiency evaluation results show high efficiency and technological progress, whereas the areas with low-efficiency evaluation showed a feature of the improving technical efficiency.

In the case of radiation workers in medical institutions, radiation exposure is made for patient protection and accurate procedures, so they have a problem of low dose exposure. Low-dose radiation exposure occurs mainly in parts of the body other than the Apron area, and the most frequent place is the skin of the back of the hand. In particular, since the medical personnel's hands require senses and fine movements during the procedure, they are defenseless in the radiation exposure area and are at risk of exposure. It can solve the problem of shielding such as lead gloves, and it is difficult to use by suggesting the activity of the hand during the procedure. To solve this problem, a shielding cream capable of obtaining a functional radiation protection effect was developed and its shielding performance was compared with lead equivalent of 0.1 mmPb. In the process of manufacturing shielding cream, the shielding performance was improved by adding a defoaming process to reduce air holes to increase the density of the cream. Therefore, the shielding cream using barium sulfate as the main material has a lower shielding rate than the lead plate, and in the realm of effective energy, it is 59%, At high effective energy, a difference of about 37% was shown, indicating that there is a functional radiation protection effect. The advantage is that it can be used directly on the skin, and it is considered that it can be used before wearing surgical gloves and has a permanent protective effect.

The Canadian military participated in World War I and felt the limitations of the recruitment system through the continuous shortage of troops caused by the prolonged war, therefore expanded the role and scope of female manpower. The use of female manpower, which began with medical support for the first time, increased its necessity and importance as medical support personnel were dispatched overseas and women's manpower was expanded to combat support missions for the Army, Navy, and Air Force. Since then, the proportion of female manpower has been limited to 1.5% of the total number of employees at the end of the Second World War and the reduction of troops and the dismantling of the women's unit. In this situation, the Austrian Defence Force gradually accepts the recommendation of the Royal Canadian Women's Status Committee to improve the service conditions of women, marking a turning point in expanding the role of women in the Canadian military. The the Austrian Defence Force conducted long-term combat experiments to increase the proportion and role of female manpower, increasing reliability through observation and analysis to prove whether female manpower is suitable for combat troops. Korea also wants to draw implications for the future direction by comparing the history and current appearance of the Canadian military's use of female manpower with the Korean military at a time when the problem of a shortage of troops is emerging due to the recent decline in fertility and low birth rates.
