Presently, there is increasing demand for geriatric nursing care because of increasing preparation of elderly population due to extended age. Of particular importance in determining the effectiveness of nursing care given to the elderly is the attitude of the nurse toward the elderly patient. Knowledge of the various changes that usually occur with aging will enable the nurse to help an aged Person maximize his potential in illness and in health. The objectives of this study were : 1. To delineate the attitudes of nurses toward the geriatric nursing care. 2. To learn the influencing factors affecting the attitudes of nurses toward the geriatric nursing care. The study population defined and randomly selected is 225 nurses at one general hospital, one private hospital, two national hospitals in Seoul during the period of October l0th -20th, 1975. The questionnaire method was used. Respondents were 140 nurses. X$^2$- test and t- test were employed in analyzing the data. The questionnaire form included 54 statements which concerned the attitudes of nurses to-ward geriatric nursing care. It was divided into five areas : 1) General characteristics of study population. 2) The nurse's concepts of elderly. 3) Care of the geriatric patient. 4) Interpersonal relationship with geriatric patient. 5) Teaching of the geriatric patient. Each of the 54 statements of the questionnaire was considered to be either Positive or Negative. A Positive response was assigned the value of+1 , and a Negative response or no response was assigned the value of O. The results of the study were as follows : 1. The Investigation of attitudes of nurses toward geriatric nursing care. a. Data indicated , respondents have negative attitudes in their. concepts of elderly (74.3%) b. Data indicated respondents have positive attitudes in care of geriatric patient (64.3%). c. Data indicated respondents have positive attitudes in interpersonal relationship with geriatric patient (85% ). 4. Data indicated respondents have positive attitudes in teaching of geriatric patient (89.3%). 2. The results of study regarding the five hypothesis were as follows : a There was significant difference in the mean scores between the attitudes of nurses toward the geriatric nursing care and level of education of the nurse. b. There was no significant difference between the attitudes of nurses toward the geriatric nursing care and clinical experience, but there was significant difference between care of the geriatric patient and clinical experience. c. There was no significant difference between the attitudes of nurses toward the geriatric nursing care and shift most frequently worked, but there was significant difference between care of the geriatric patient and shift most frequently worked. d. There was no significant difference in the mean scores between the attitudes of nurses toward the geriatric nursing care and marital status, but there was significant difference in the mean scores between interpersonal relationship, teaching of geriatric patient and marital status. e, There was no significant difference in the mean scores between the attitudes of nurses toward the geriatric nursing care and experience with elderly, but there was significant difference in the mean scores between care of geriatric patient and experience with elderly.
The study was conducted with statical analysis of data (828 data in 2010, 752 data in 2012, 648 data in 2014) in order to evaluate laboratory awareness difference of research employees working in different types of universities. Results of the study were as follows: First, university institutes in the order of polytechnic colleges, university, and junior college showed the highest laboratory safety awareness in 'awareness and education of laboratorial safety regulation' and 'awareness in laboratory risk factors'. Second, the difference in safety awareness of universities by year(years that conducted current status survey) was the highest in year 2014, then in 2010, and in 2008. Third, the difference of research employees working for laboratory safety management by year(years that conducted current status) showed that university had the highest laboratory safety awareness in year 2010, but it changed to polytechnic colleges in year 2012 and 2014. Through this study, we could recognize the difference in safety awareness of research employees working in university institutes.
Background: The purpose of this study was to confirm whether surface FES was effective in the function of chronic stroke patients' affected shoulder and whether FES influenced their functional abilities in ADL, as well. Method: the subjects were inpatients at a general hospital in Gyeonggi-Do, Korea and had been diagnosed as a sub-luxation in their affected shoulder. They were 26 and were separated to an experimental group and a control group, in equal number. Both groups had gotten an exercise treatment for 6 weeks. The control group didn't get any FES as opposed to the experimental group. Result: in the experimental group there was no statistical significant difference in the vertical space and the joint space, even though the space was reduced. In the control group, there was no statistical significant difference, either. Moreover, each space of their shoulders was increased. In the range of motion of each group, there was no statistical significant difference. In functional independent ability, there was a significant difference in an experimental group. In contrast, there was no difference in a control group. Conclusion: this result suggests that FES should be effective in the sub-luxation of the patients' affected shoulder and the range of motion of their shoulders. On the other hand, compared to the previous items, FES was quite effective in the functional improvement.

Objectives : In the study on the waveform analysis of radial artery pulse diagnosis, we need to establish fundaments of contemporary pulse diagnosis research, and to find the change of pulse waveform parameter with applied variation pf pressure. Methods : As we will to do experimental research on the difference of pulse waveform on the radial artery with applied variations of pressure(5 stage-pressure) and measuring position(left KWAN). In this research, we analyzed the change of the waveform according to five stage pressure. Results : The results were as follows; When we analyzed the change of the waveform according to pressure in the left KWAN, E, hl, h2 and A were the difference between 8ths pressure grades in 95% trust section. And t2, t4 were the difference between 8ths pressure grades in 95% trust section. W was the difference between 8ths pressure grades in 95% trust section. And h2/h1 was the difference between 6ths pressure grades in 95% trust section. There is the difference between 1st and 2nd grade & between 2nd and 5th grade in the case of t4/t2 in 95% trust section. And there is the difference between 1st and 5th grade, between 3rd and 4th grade, between 3rd and 5th grade & between 4th and 5th grade in the case of W/A in 95% trust section. And there is the difference between 1st and 2nd grade, between 2nd and 3rd grade, between 2nd and 4th grade, between 3rd and 4th grade, between 3rd and 5th grade & between 4th and 5th grade in the case of A/E in 95% trust section.

And Analysing the radial pulse(left KWAN) at 5 applied pressure levels may be useful to study on the pulse waveform diagnosis.
To develop the diet for Korean type 2 diabetic patients, a consumer survey was conducted (N=35) and was analyzed statistically. The survey compared the results of a questionnaire, somatometry, and blood parameters before and 8 weeks after the experiment. It was divided into Diabetic diet enforcement group (DDE) vs. Non diabetic diet enforcement group (NDDE). There was no significant difference in body weight, body mass index (BMI), body fat, triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) of the subjects before and 8 weeks after the experiment. DDE's average fasting glucose (FBG) and post prandial 2 hours blood glucose (PP2) were significantly decreased before and after the experiment (p<0.05). NDDE's average FBG and PP2 showed no significant difference. In terms of Hemoglobin $A_lC\;(HbA_1C)$ content, DDE's had significantly decreased level both before and after the experiment (p<0.05), while there was no significant difference in the NDDE group. Cholesterol and High density lipoprotein cholesterol (HDL-C) were significantly different in DDE (p<0.05) both before and after the experiment. Whereas in the case of NDDE, there was no significant difference on the cholesterol and HDL-C, while DDE's showed a significant difference before and after the experiment. In terms of patients distribution depending on their treatment (p<0.05), NDDE had no significant difference before and after the experiment. For an item asking blood glucose control, DDE had significant difference before and after the experiment (p<0.01), while NDDE had no significant difference. For program satisfaction (p<0.05) and health (p<0.001), both the groups changed significantly after the experiment. But there was no significant difference in applying it to their real life after the experiment. Based on these results, DDE had the decreased blood glucose levels, $HbA_1C$, and cholesterol and increased HDL-C, with decreased rate of the patients taking oral hypoglycemic agents. In addition, many of the patients who participated in the experiment were found to be satisfied with the program, in terms of having less trouble in glucose control and exhibited improvement in health. Hence, based on the above results it was concluded that program was a very successful one for the treatment of diabetes.
In this research, fiber-optic pressure sensors were fabricated with rugate-structured porous silicon (RPS) diaphragms coated with PMMA (Polymethyl-Methacrylate). The reflectance spectrum of the PMMA/RPS diaphragm was almost the same as that of uncoated RPS diaphragm. However the mechanical strength of the PMMA/RPS diaphragm increased more than that of the uncoated diaphragm. As a result, the fiber-optic sensor fabricated with PMMA/RPS diaphragm could successfully detect more high pressure difference without diaphragm damage than the highest detectable pressure difference of the sensor with normal RPS diaphragm. The response data of the fiber-optic sensor recorded as a function of pressure difference were fitted by theoretical curves. During this process, elastic moduli of the used PMMA/RPS diaphragms were obtained numerically. The dynamic response properties of the fiber-optic sensor were also investigated under continuous variation of the pressure difference conditions.
Reversible data embedding theory has marked a new epoch for data hiding and information security. Being reversible, the original data and the embedded data as well should be completely restored. Difference expansion transform is a remarkable breakthrough in reversible data hiding scheme. The difference expansion method achieves high embedding capacity and keeps the distortion low. This paper shows that the difference expansion method with simplified location map, and new expandability and changeability can achieve more embedding capacity while keeping the distortion almost the same as the original expansion method.

In recent years, sensorless drive schemes have been proposed widely and most of them are based on the ZCP (Zero Crossing Point) detection of the BEMF (Back Electro-Motive Force). These schemes have two main problems. One is that ZCP may not be detected at low speed and thus a forced drive is required. The other problem is that there is $30^{\circ}$ phase difference between ZCP and the motor commutation instant and to ensure proper operation, this gap should be accounted for. To solve these problems a circuit is devised for detecting ZCP of the BEMF difference through the line voltage difference. Experimental results show that the output of this circuit is identical to that of the Hall sensor signal, and velocity control of a BLDC motor is possible without the sensor.
Let G be a (p, q) graph. Let f be a map from V (G) to {1, 2, ${\ldots}$, p}. For each edge uv, assign the label ${\mid}f(u)-f(\nu){\mid}$. f is called a difference cordial labeling if f is a one to one map and ${\mid}e_f(0)-e_f(1){\mid}{\leq}1$ where $e_f(1)$ and $e_f(0)$ denote the number of edges labeled with 1 and not labeled with 1 respectively. A graph with admits a difference cordial labeling is called a difference cordial graph. In this paper, we investigate the difference cordial labeling behavior of triangular snake, Quadrilateral snake, double triangular snake, double quadrilateral snake and alternate snakes.

A compensation strategy for the phase-difference control method, which has been reported as a new driving method of a 2-phase inverter-fed induction motor, is proposed. The phase-difference control method extends the control range of the speed and eliminates the harmonic contents of the output voltage of the 2-phase inverter-fed induction motor. However, the phase-difference angle becomes narrower, motor efficiency deceases more and pulsating torque increases more. As the counterplan for these shortcomings of the phase-difference control method, a hybrid control method which combines the phase-difference control with the voltage control is proposed. The algorithm to realize a hybrid method is presented. As an example, a model composed of 5 regions has been analyzed by computer simulation in terms of motor performance and the results have been compared with experimental results.
