The aim of this survey is to investigate the occupational musculoskeletal disease and stress levels of restaurant cooks and to provide a basic data of programs in order to prevent occupational diseases. A questionnaire survey was conducted on 220 subjects in Gangwon province. The results show that there was no significant difference in the degree of occupational musculoskeletal disease between male cooks and female cooks. However, western cuisine cooks were more likely to have a higher degree of occupational musculoskeletal disease than other cuisine cooks and showed a higher degree of occupational stress from work overload as well as irregular meal stresses. Cooks aged from 30 to 40 years showed a higher level of occupational musculoskeletal disease in the neck, shoulder, and hand/wrist compared to those in other age groups. The job tenure was related to the degree of musculoskeletal disease in knee. Additionally, the hours of working per day were statistically significantly related to musculoskeletal disease in the knee and to the occupational stress levels in irregular meals stress. The findings of this study suggest that it is essential to design customized education for cooks to lessen their occupational musculoskeletal diseases and stresses in order to ensure the health and safety of the culinary workers.

In this paper, we propose a new monitor for collecting job information from Hadoop clusters in real time. This monitor is made of two programs called Collector and Agent. Agent collects Hadoop cluster's node information and job information, and Collector analyzes the collected information and saves it in a database. Also, Collector was placed in a new node outside the Hadoop cluster so that it does not affect Hadoop's work and will not cause overload. When the proposed monitor was implemented and applied, the testbed cluster was able to detect the occurrence of dead nodes immediately. In addition, we were able to find Hadoop jobs which were inefficient and when we modified such jobs to further enhance the performance of Hadoop.

Purpose: To investigate the perception and barriers of Kangaroo-Mother Care (KMC) among nurses in Neonatal Intensive Care Units (NICU). Methods: Participants were 131 nurses working in NICU who completed self-report questionnaires which included information regarding perception, barriers, and practice of KMC. Collected data were analyzed using SPSS 18.0 program for descriptive statistics, t-test, ANOVA, and Pearson correlation coefficients. Results: Of the participants, 33.6% reported the practice of KMC in their NICU, with 75.6% wanting to receive training in KMC and 31.3% having received KMC education. Most of the participants agreed that KMC enhances attachment, parental confidence, and effective breast feeding but they reported a negative perception in providing KMC for premature infants weighing less than 1000 grams or intubated premature infants. Major barriers to practicing KMC were safety of infants, possible work overload for nurses, as well as absence of consistent guidelines. Barriers to KMC among nurses who received the KMC training were lower than nurses who did not receive the KMC training (t=-2.11, p=.037). Conclusion: Education program and standardized clinical practice protocol should be developed to foster the positive perception and to reduce nurse barriers to KMC.

Purpose: This study was done to develop strategies for better education and career adaptation of nursing students by investigating the recognition and intentions of nursing students and graduates on the nursing and a future career. Method: Data was collected from a survey conducted between the 1st of October and 5th of December, 2007. Participants were 113 students and 37 graduates of one nursing college. Result: The majority of participants thought that atmosphere and relationships were important criteria to choose a job. Most of them selected nursing major not because their aptitude but because of its professionalism and job stability. Most wanted to go to graduate school and were interested in a nurse specialist program, especially for critical and emergency care. The preferred nursing role changed from recovery care to health promotion as they advanced in their studies. They thought work overload and fatigue from three shift as barriers for a longer stay as a clinical nurse. Conclusion: This study is meaningful in a way that it suggests some strategies for promoting nursing professionalism and adaptation to working field. In order to generalize the results of this study, replicate studies need to be conducted with nation-wide samples.

This study examined the expenditure on time-saving services and related variables. The time-saving services are food away from home, delivery food, dry cleaning, clothing care, helper and total service. The specific objectives of this study were: (1) to investigate the differences in the expenditure on time saving services according to social economic and demographic variables. (2) to investigate the differences in the expenditure on time-saving services according to role-overload, home goal orientation and work goal orientation. (3) to investigate the independent influence of variables related to the expenditure on time-saving services. For this objectives survey was conducted using interview. The data used in this study included 160 women living in Seoul from employed professional housewives, employed non-professional housewives and non-employed housewives. Statistical analyses were conducted using frequencies, percentiles, mean, oneway ANOVA, DUNCAN-test and multiple regression. The major findings were: (1) Wife's education, wife's age, income, tenure, level of living and employment status were significantly related to the expenditure on time-saving services by using the one-way ANOVA. (2) Income, education, level of living, number of children, and employment status explained the variance of the expenditures on time-saving services about 20%-39% by using a multiple regression method.

The sympathico-adrenergic system and the hypophyseal-adrenocortical system mediates the regulation of the internal milieu. And the kidneys regulate both water and electrolyte balance of the body fluid. The kidneys are the sites of production of renin which participate indirectly in maintaining renin. angiotensin-aldosterone system. These system de-serve special attention in the context of adjustment the effects on the body function. And so, maximal exercise and work load are associated with home-osthetic function. The nurses working in the hospital have been complained of fatigue and stress by frequent duty changes and overload. In order to define this, the possible changes of hormonal excretion during three-shift nursing practice were investigated. Urine samples were collected at pre-duty and post-duty, and were measured with chemical assay and radioimmunoassay in 30 nursing students, in nursing practice and 43 nursing students, in studying. The results obtained were as follows. 1. In nursing practice, urinary norepinephrine concentration showed a marked increase during day duty, urinary cortisol concentration showed a marked increase during evening duty, and urinary renin concentration was increased in night duty, 2. Corrected ratio of urinary sodium excreted by the urinary excretion of creatinin (UNa/UCr) and UCl/UCr showed a marked decrease during night duty. Nursing practice did not affect on the UK/UCr and urinary concentrating ability. From these results, it is suggested that further studies the define the effects on some physiological function of the three-shift nursing practice against circadian rhythm are needed for better working condition of nurses.

The package loading process of the lumbering industry is an operation that after a pair of workers bind three or six lumbers into one unit and cut both ends of the lumbers, transports the weight cargo of 30-50kg by one meter, pack and load at a height of 1.2 meters. This package loading process causes lots of noise and wood dust when workers carry out the heavy work as the above. Therefore we developed the monolithic both ends cutting package loading equipment in order to prevent from getting musculoskeletal disease. An loading bar working system of this equipment is improved from pneumatic pressure system to oil pressure system, furnished the newly designed flow dividers, and developed the new system that a both end array is loaded identically. Also we developed the safety equipment of loading bar in order to prevent workers mistake and overload from malfunction during the package loading process. The main cause of job evasion on working place could be solved by preventing the musculoskeletal disease and improving the working environments.

This study aimed to investigate current nutrition education and effective plans for nutrition teachers in schools. Data were collected by a face-to-face questionnaire. Surveyed schools were elementary, middle, and high schools at percentages of 32.4%, 35.1%, and 32.4%, respectively. Percentage of nutrition education was above 90%, whereas off-line education was very uncommon in middle (8.3%) and high schools (27.3%) compared with elementary schools (63.6%), (p<0.05). Satisfaction of nutrition education was also very low in middle (7.7%) and high schools (8.3%) when compared with elementary schools (41.7%), (p<0.05). The main reason for this was due to 'work overload of mealing service (44.4%)' and 'insufficient time of students (25.9%)'. Effective education plans were as follows: beginning of education and education scale were 'elementary school (67.6%)' and 'below 20 people (81.1%)', and the most preferred counterplan was 'development of diverse education programs (4.81 score)' > 'systematic education process (4.76 score)' > 'professional nutrition education (4.51 score)'. Most important duty was 'nutrition education and consultation (51.4%)', although it achieved the lowest satisfaction at a score of 2.46. Overall analysis, demand and awareness of nutrition teachers for nutrition education were very high. Therefore, an institutional strategy and environmental improvements are required by setting up curriculum subjects and developing diverse education programs for systematic nutrition education.

In order to develop a multi-type heat pump system with two indoor units of non-uniform capacities, the optimum refrigerant circuit was developed using capillary tubes. The refrigerant circuit was composed of four main parts, a heating circuit, a cooling circuit, a by-pass circuit and a balance circuit. The system characteristics of multi-type heat pump was investigated through the rating test and the reliability test, using the multi-type psy-chrometric calorimeter. The results of the rating test showed that the capacity of the multi-type heat pump was about 93% of the design value. In particular, the capacity of cooling single mode was about 13% higher than the design value, and the capacity of heating multi mode was about 5% higher than the design value. The reliability of the multi-type heat pump was verified by various reliability tests (overload, extension tube, freeze up, under/over charging, sweat, flood back). The optimal amount of refrigerant charge and compressor capacity were determined from the present work.

We propose a mechanism for monitoring load in quality of service (QoS)-enabled wireless networks and show how it can be used for network management as well as for dynamic pricing. Mobile network traffic, especially video, has grown exponentially over the last few years and it is anticipated that this trend will continue into the future. Driving factors include the availability of new affordable, smart devices, such as smart-phones and tablets, together with the expectation of high quality user experience for video as one would obtain at home. Although new technologies such as long term evolution (LTE) are expected to help satisfy this demand, the fact is that several other mechanisms will be needed to manage overload and congestion in the network. Therefore, the efficient management of the expected huge data traffic demands is critical if operators are to maintain acceptable service quality while making a profit. In the current work, we address this issue by first investigating how the network load can be accurately monitored and then we show how this load metric can then be used to provide creative pricing plans. In addition, we describe its applications to features like traffic offloading and user satisfaction tracking.
