We propose and develop Home Security robot system based on Sensor Network (HSSN) configured by sensor nodes including radio frequency (RF), ultrasonic, temperature, light and sound sensors. Our system can acknowledge security alarm events that are acquired by sensor nodes and relayed in the hop-by-hop transmission way. There are sensor network, Home Security Mobile Robot (HSMR) and Home Server(HS) in this system. In the experimental results of this system, we presented that our system has more enhanced performance of response to emergency context and more speedy and accurate path planning to target position for arriving an alarm zone with obstacle avoidance and acquiring the context-aware information.

Purpose: This study was conducted to assess the working conditions of home health nurses in hospital-based home health institutions nationwide. Methods: A secondary data analysis study was conducted based on the survey data on the working conditions of home health nurses, jointly conducted by the Korean Home Health Care Nurses Association and the Academic Society of Home Health Care Nurses in September 2020. Results: Of the home health nurses respondents, 82.4% worked in tertiary hospitals and general hospitals. Most of the working hours of home health nurses were 40 hours a week. Traffic accidents accounted for a significant proportion of accidents experienced by the home health nurse while performing their duties. Most of welfare and benefits systems applicable to home health institutions were in place. The time allocated to provision of home health nursing services was usually more than 30 minutes but less than 1 hour. The type of position of the individual in charge of home health care differed according to the type of medical institution. Conclusion: It is recommended that continuous investigation and analysis be conducted in order to establish a direction for improvement of home health nurses' working conditions, based on the related accumulated data.

Purpose: This study was aimed to investigate predictors of job satisfaction of home visiting nurses at the 16 public health centers in Busan. Method: There are two groups of independent factors: non-work related (age. educational level. working duration as nurses in hospitals. certificate). and work related (working duration as nurses in public health centers. working duration as home visiting nurse. position. number of households visited per week, workload, cooperation among staff, support by supervisors, supply of vehicles, supply of materials). The participants were 88 home visiting nurses from 16 public health centers in Busan. Data were collected with self-administrated questionnaires and analysed using an univariate logistic regression and multiple logistic regression analysis. Result: support by supervisors (good vs not-good, OR=3.70. p=0.025), and supply of materials (good vs not-good, OR=3.33, p=0.038) had significants effects on job satisfaction. Conclusion: The results were similar to those of other studies on the predictors of job satisfaction of clinical nurse at hospitals, and were helpful in developing nursing interventions to increase job satisfaction among home visiting nurses in public health centers.

Fatty acids of Gingko biloba lipid and its binding position were determined by using pancreatic lipase. Optimum conditions for hydrolysis of glyceride were found as 9mg of lipase and 5 min reaction time for 50 mg of TG. The results showed that oleic acid and linoleic acid were presented about 40% and 29.7%, respectively, but linoleic acid was very small comparing with other seeds. It was found that both saturated and unsaturated fatty acids were almost equally distributed at ${\beta}\;and\;{\alpha}{\cdot}{\alpha}'-position$ of TG.

This study investigated the relation between parents' verbal control modes and children's maladjustment. The subjects were 445 mothers and their children of sixth grade in elementary schools located in Seoul. To assess the parents' verbal control modes, questionnaire developed by Lee Kyung Hee(1993) was used. The modified version of Achenbach and Edelbrock's CBCL(Child Behavior Checklist) was administered to assess the children's maladjustment. The results were as follows : 1)Significant differences were found in parents' verbal control modes in terms of children's sex difference and social status level. 2) Significant differences were found in children's maladjustment in terms of children's sex difference and social status level. 3) There was a significant correlation between father's verbal control modes and children's maladjustment. Children's maladjustment was related positively to imperative mode and negatively to the person-oriented and position-oriented modes. The best variable explaining girl's maladjustment was father's position-oriented modes. 4) The negative impact of father's imperative mode in combination with the mother's imperative mode on the children's adjustment was greater than other combinations of the father and mother's verbal control modes.

PMAC(Permanent magnet AC) motor drives are widely used in the industrial applications and home appliances because of high torque ratio, high efficiency and precise control performance. In recent years there has been a significant development of PMAC motors of various kinds. Improvements in the properties of permanent magnet materials have increased the viability of related types of motors. However, precise speed and position information is essential for the good control performance. In order to produce correct torque, the rotor flux position information from position sensor has to be identified. In this paper, a low cost position sensor is proposed for improving of starting and low speed performance of PMAC. The proposed position ...

The purpose of this study was to examine the relationships among the father's involvement in child-rearing, psychological life position, and child's prosocial behavior. The subjects of this study were four- and five-year-old, kindergarten children (N=261) and their fathers who tved in Incheon. A questionnaire was used and analyzed by frequency, percentile, mean, standard deviation, Cronbach's ${\alpha}$, t-test, ANOVA, and Pearson's correlation. Fathers who took a positive altitude to themselves and others showed more positive involvement in various child-rearing activities such as shared activities with children, supporting cognitive-social development, and child caregiving and monitoring. In addition, children reared by fathers who had a higher positive attitude to others helped their friends well. As the father's developmental support in child-rearing became more positive, the children's prosocial behavior increased.

PMSMS (permanent magnet synchronous motors) are widely used in industrial applications and home appliances because of their high torque to inertia ratio, superior power density, and high efficiency. For high performance control, accurate informations about the rotor position is essential. Sensorless algorithms have lately been studied extensively due to the high cost of position sensors and their low reliability in harsh environments. A novel position sensorless speed control for PMSMs uses indirect flux estimation and is presented in this paper. Rotor position and angular velocity are estimated by the proposed indirect flux estimation. Linkage flux and magnetic field flux are calculated by the voltage equations and the measured phase current without any integration. Instead of linkage flux calculation with integral operation, indirect flux and differential magnetic field are used for the estimation of rotor position. A proper rejection technique fur current noise effect in the calculation of differential linkage flux is introduced. The proposed indirect flux detecting method is free from the integral rounding error and linkage flux drift problem, because differential linkage flux can be calculated without any integral operation. Furthermore, electrical parameters of the PMSM can be measured by the proposed TCM (time compression method) for soft starting and precise estimation of rotor position. The position estimator uses accurate electrical parameters that are obtained from the proposed TCM at starting strategy. In the operating region, a proper compensation method fur temperature effect can compensate fir the estimation error from the variation of electrical parameters. The proposed novel position sensorless speed control scheme is verified by the experimental results.

Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.
