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.
This study was carried out to develop a belt pick-up type one-row soybean cutter, using physical properties and production conditions of soybeans. The prototype soybean cutter consisted of 4 parts: cutting part, conveying part, collecting part, and travelling part. The prototype soybean cutter was designed to cut soybeans planted with a row spacing of 600 mm, and at a height of 30 mm from the bed bottom using a disk saw. Through various trials with different peripheral velocities of the disk saw and forward speed of the cutter, determined ranges of the peripheral velocity of the disk saw cutting soybeans stems were greater than 18.3 m/s. Spacing between pick-up belts (clearance) was in a range of 60~90 mm so that soybeans could be picked at heights greater than 25 cm, and the size and shape of the pick-up belt were determined the conventional manual harvesting method. The optimal ratio between the forward speed of cutter and the peripheral speed of pick-up belts were from 1 to 1.2 by theoretical analysis. the pick-up belts had a $35^{\circ}$ of tilted angle and $90^{\circ}$ of twisted angle to pick up soybeans safely from the plant input to the lower end of the belts and convey soybeans to the upper end of belts nearby a container. The soybeans at the rear container were dropped down on the soybean row with an interval. The effective field capacity of the prototype soybean cutter was 0.136 ha/h, reducing the working hour by 92% when compared with the manual cutting.
The purpose of this study is in the investigation to relieve into the clothing inconvenience levels and to need by arthritis patients who experience clothing difficulties in daily living even without showing conspicuous physical disabilities. For this study, personal interviews were carried out with 151 female arthritis patients, using a questionnaire form consisting of a total of 206 items. Data analysis were done with spss 12.0 for the frequency analysis, cross tab analysis, t-test, and ANOVA. The findings are as follows. 1. The survey subjects were diverse in their age from 20s to 60s and 18.5% of them have need of other's assistance at the time of getting dressed or undressed of clothing. The knee part was felt to be the most uncomfortable, causing the inconveniences in wearing pants or panties. 2. The investigation into the inconvenience levels at the time of dressing or undressing of clothing was indicated that the wearing of pants was the hardest movement to arthritis patients, as the items relating to the movements for putting feet into or pulling them out of pants and those for raising pants over the hip were also accompanied by the feeling of pains. In addition, the aged arthritis patients felt the clothes-wearing movements more difficult. 3. The survey on the kind and inconvenience levels for the clothes currently being worn showed the highest wearing ratio for the pants, which were pointed out to be the most inconvenient. 4. As for the clothing improvement, the needs were located as a whole in the sufficiency in measures of pants crotch and circumference items, the flexibility in materials, the short length of pants, or the front clearance.

The present study numerically investigates the aerodynamic characteristics of two-dimensional wings in the vicinity of the ground by solving two-dimensional steady incompressible Navier-Stokes equations with the turbulence closure model of the realizable k-${\varepsilon}$ model. Numerical simulations are performed at a wide range of the normalized ground clearance by the chord length ($0.1{\leq}h/C{\leq}1.25$) for the angles of attack ($0^{\circ}{\leq}{\alpha}{\leq}10^{\circ}$) in the prestall regime at a Reynolds number (Re) of $2{\times}10^6$ based on free stream velocity $U_{\infty}$ and the chord length. As the physical model of this study, a cambered airfoil of NACA 4406 has been selected by a performance test for various airfoils. The maximum lift-to-drag ratio is achieved at ${\alpha}=4^{\circ}$ and h / C = 0.1. Under the conditions of ${\alpha}=4^{\circ}$ and h / C = 0.1, the effect of the Reynolds number on the aerodynamic characteristics of NACA 4406 is investigated in the range of $2{\times}10^5{\leq}Re{\leq}2{\times}10^9$. As Re increases, $C_l$ and $C_d$ augments and decreases, respectively, and the lift-to-drag ratio increases linearly.

Background: Due to multiple similarities in the structure and physiology of human and pig skin, the pig model is extremely useful for biological drug testing after subcutaneous administration. Knowledge of the differences between subcutaneous injection sites could have a significant impact on the absorption phase and pharmacokinetic profiles of biological drugs. Objectives: This study aimed to analyze the impact of administration site on pharmacokinetics and selected biochemical and hematological parameters after a single subcutaneous administration of ustekinumab in pigs. Drug concentrations in blood plasma were analyzed by enzyme-linked immunosorbent assay. Pharmacokinetic analyses were performed based on raw data using Phoenix WinNonlin 8.1 software and ThothPro v 4.1. Methods: The study included 12 healthy, female, large white piglets. Each group received a single dose of ustekinumab given as a 1 mg/kg subcutaneous injection into the internal part of the inguinal fold or the external part of the inguinal fold. Results: The differences in absorption rate between the internal and external parts of the inguinal fold were not significant. However, the time of maximal concentration, clearance, area under the curve calculated between zero and mean residence time and mean residence time between groups were substantially different (p > 0.05). The relative bioavailability after administration of ustekinumab into the external part of the inguinal fold was 40.36% lower than after administration of ustekinumab into the internal part of the inguinal fold. Conclusions: Healthy breeding pigs are a relevant model to study the pharmacokinetic profile of subcutaneously administered ustekinumab.
When the amplitude of the vibrations is equivalent to that clearance, the vibrations for small amplitudes will really be significantly nonlinear. Nonlinearities will not be significant for amplitudes that are rather modest. Finally, nonlinearities will become crucial once again for big amplitudes. Therefore, the concrete panel system may experience a big amplitude in this work as a result of the high temperature. Based on the 3D modeling of the shell theory, the current work shows the influences of the von Kármán strain-displacement kinematic nonlinearity on the constitutive laws of the structure. The system's governing Equations in the nonlinear form are solved using Kronecker and Hadamard products, the discretization of Equations on the space domain, and Duffing-type Equations. Thermo-elasticity Equations. are used to represent the system's temperature. The harmonic solution technique for the displacement domain and the multiple-scale approach for the time domain are both covered in the section on solution procedures for solving nonlinear Equations. An effective data-driven solution is often utilized to predict how different systems would behave. The number of hidden layers and the learning rate are two hyperparameters for the network that are often chosen manually when required. Additionally, the data-driven method is offered for addressing the nonlinear vibration issue in order to reduce the computing cost of the current study. The conclusions of the present study may be validated by contrasting them with those of data-driven solutions and other published articles. The findings show that certain physical and geometrical characteristics have a significant effect on the existing concrete panel structure's susceptibility to temperature change and GPL weight fraction. For building construction industries, several useful recommendations for improving the thermo-mechanics' behavior of structural concrete panels are presented.
The purpose of this study was to examine the effect of D-ribose supplementation on the changes of blood fatigue substances (lactate, ammonia, phosphate and hypoxanthine) after maximal exercise performance in college male students. The experimental trials of each subject were divided into the following conditions: placebo supplement trial and D-ribose supplement trial. The subjects exercised using a Concept II Indoor rowing ergometer for 2,000 m Single Skull event. The subjects ingested 200 mg/kg of D-ribose after breakfast, lunch, dinner, as well as thirty minutes before exercising, for six days. Blood fatigue substances were continuously measured before exercise, immediately after exercise, and thirty minutes after exercise. The results indicated a significant difference in blood phosphate and hypoxanthine levels between the two experimental trials in the 30 minute recovery period (p<0.05). However, there were no significant differences in blood lactate and phosphate levels between the two experimental trials. The results of our study suggest that D-ribose supplementation during maximal rowing exercise for 7~8 minutes may contribute to the improvement of metabolic responses as a beneficial ergogenic aid accelerating fatigue clearance.
The purpose of this study were to analyze the home care services and to evaluate the client's satisfaction with the home care services provided by home care service center in the C hospital. The data were collected by reviewing charts of 128 home care clients who were receiving home care services at C hospital from October 1997 to September 2000. The subjects for satisfaction of home care service were 20 clients from July 10 to September 30, 2000. The tool for measurement of present condition of home care service was developed by the researchers. The satisfactions of the home care services were measured by using the instrument developed by Im(997). The data were analyzed by using the SPSS/PC+. The results of this study were as followings : 1. Majority of the subjects was female(61.7%). The average of age was 63.5 years. The service has been used mostly by the elderly 60 years of age or older(71.1%). The economic level of most of subjects was in middle class(94.5%). 2. Majority of the subject had a cancer(55.4%), following stroke(25.0%). The average duration of disease for the subjects was 31 months. The average time of hospitalization for the subjects was 3.3 times. The duration of hospitalization was 10$\sim$30 days(26.6%), 30$\sim$60 days(23.4%) and above of the 210 days(9.4%). 3. Most of the subjects used his/her doctor (47.7%), as a consultant, following his/her nurse (28.1%), other patients or their family (21.9%). Most of reasons for a consultation were supportive management(Infusion or medication, 60.94%), following tube management(L-tube or T-tube, 25%), Foley catheter management (15.63%) etc. 4. 28 types of nursing diagnoses were used by the home care service. The nursing diagnosis altered nutrition: less than body requirement were used mostly by the home care service, following risk for infection, impaired skin integrity, impaired swallowing, ineffective airway clearance altered comfort: pain, impaired physical mobility. By the human-response pattern, exchanging(63.2%), moving(7.5%), feeling(10.4%), knowing(5.2%), communicating (2.6%), relating(0.5%) perceiving(0.4%) and choosing(0.3%). There were 42 nursing intervention types were performed by the home care service. By the NIC(nursing intervention classification. McCloskey. Bulech. 1996). physiologic: complex (30.3%) was the most, safety(28.3%), behavioral(20.0%), physiologic: basic(10.8%) and health system(1.7%). Observation or assessment was the most nursing intervention performed by the home care service. following IV infusion. vital sign observation. infusion management and fluid-electrolyte balance management. 5. The level of client's satisfaction with provided home care services showed considerably high(2.67/ 3).
Liposomes as one of the efficient drug carriers have some shortcomings such as their short circulation time, fast clearance from human body by reticuloendothelial system (RES) and limited intracellular uptake to target cell. In this study, polyethylenglycol (PEG)-incorporated cationic liposomes were prepared by ionic complexation of positively charged liposomes with carboxylated polyethyleneglycol (mPEG-COOH). The cationic liposomes had approximately $98.6{\pm}1.0nm$ of mean particle diameter and $42.8{\pm}0.8mV$ of zeta potential value. The PEG-incorporated cationic liposomes had $110.1{\pm}1.2nm$ of mean particle diameter with an increase of about 10 nm compared to the cationic liposomes. Zeta potential value of them was $12.9{\pm}0.6mV$ indicating 30mV decrease of cationic charge compared to the cationic liposomes. The amount of PEG which was incorporated onto the cationic liposomes was assayed by using picrate assay method and the incorporation efficiency was $58.4{\pm}1.1%$. Loading efficiency of model drug, doxorubicin, into cationic liposomes or PEG-incorporated cationic liposomes was about $96.0{\pm}0.7%$. Results of intracellular uptake which were evaluated by flow cytometry analysis of doxorubicin loaded liposomes showed that intracellular uptake of PEG-incorporated cationic liposomes was higher than the cationic liposomes or DSPE-mPEG liposomes. In addition, cytotoxicity of PEG-incorporated cationic liposomes was comparable to cationic liposomes. Consequently, the PEG-incorporated cationic liposomes of which surface was incorporated with PEG by ionic complex may be applicable as anticancer drug carriers that can increase therapeutic efficacy.

Purpose : This multicenter collaboratory study was conducted to see the therapeutic efficacy and side effect of cyclosporine A (Cipol-$N^{(R)}$, Chong Kun Dang) on children with idiopathic nephrotic syndrome who experienced frequently relapsing (FR), steroid dependent (SD), or steroid resistant (SR) pattern. Patients and methods : Thirty-nine children with SD/FR NS and 3 children with SR NS were enrolled in the study. After induction of remission (SD/FR NS) with steroid or after 4 weeks of steroid therapy (SR NS), cyclosporine A was started in a dose of 4-5 mg/Kg/day in two divided dose and steroid (prednisolone or equivalent dose of deflazacort) was tapered slowly. During 16 weeks of study period, monthly check up of physical examination and various laboratory tests including BUN, creatinine, Ccr and cyclosporine blood level were done. Results : Out of 39 children with SD/FR NS, 35($89.7\%$) maintained sustained remission and at 4 weeks after therapy, values of serum protein, albumin, cholesterol, and 24 hours urinary protein excretion showed normal values. Two out of 3 children with SR NS showed and sustained remission with cyclosporine A therapy. Side reaction to cyclosporine A therapy showed hypertrichosis in 8 cases and hyperuricemia in 5 cases. However, other laboratory tests including CBC, liver profile, BUN, creatinine and GFR (creatinine clearance utilizing 24 hour urine) did not show any abnormalities during the 16 weeks of study period. Conclusion : Cyclosporine A (Cipoi-$N^{(R)}$ Chong Kun Dang) can be utilized quite effectively on children with SD/FR or SR NS and further trial of cyclosporine A on long-term basis (1-2 year period) is needed to determine it's efficacy and side effect (especially nephrotoxicity) of long-term administration of cyclosporine A.
