This study was formed to propose a theoretical background trying to create a positive delivery experience by understanding college women's subjective accounts (their view and attitude) on delivery. Method: Q- methodology was used to appreciate the highly abstract concept in an objective manner, since delivery can be assessed differently with each experience. Result: There were three types of opinions about the delivery in college women. The first type (matured type) understood delivery to be a precious experience that enables women to gain the value of life through labor pain, and granted then more appreciation to their own mothers. The second type (will type) recognizes delivery as an option rather than an obligation for women. They think women chooses whether or not to experience the process, especially since delivery requires a great deal of responsibility. The third type (positive type) takes delivery as a valuable, worthwhile, and marvelous process that they wish to experience. They are not even afraid of giving birth multiple times. Conclusion: The study explains and allows us to understand college women's overall opinion and attitudes about delivery. Thus this study aids the seizure of an opportunity to build a theoretical base for delivery management.
In this study, the authors carried out experiments and numerical simulations in order to clarify the pressure pulsation characteristics in multiple-delivery rotating-cam and stationary-cylinder type radial piston pumps. Also, a tee filter was applied to the pump in order to mitigate the pressure pulsation. Through the experiments and simulations, it was known that pressure pulsation with a magnitude higher than 40% of the mean load pressure could occur in the pump used in the experiments. Moreover, it was confirmed that a tee filter designed in this study could effectively mitigate the pressure pulsation.

The purpose of this research is to explore the necessity of utilizing IPD methods along BIM based project operation in domestic construction market. IPD is relatively new project delivery methods focused on the collaboration of stockholders based on BIM technology. IPD is focused on the multiparty contract process rather than multiple bilateral contracts under Traditional Project Delivery Methods. The research method is to investigate the IPD standard contract documents, successful IPD project cases in the U.S. The research results are as follows. The model for an IPD standard contract needs to be developed for the application to a real construction projects. Various types of IPD model contract need to be developed to accommodate the requirements of industry and stockholders in Korea.

Low toxicity, reverse thermal gelation and high drug loading capabilities suggest that poloxamer 407 gels have great potential as a topical drug delivery system. Kojic acid (KA) is an antimelanogenic agent which has been widely used in cosmetics to whiten the skin color. However, it has the drawbacks of skin irritancy due to its acidic pH. Poloxamer gels of different polymer contents were formulated to overcome the problem and compared to the cream type formulations of either w/o/w multiple emulsion cream or o/w type emulsion cream. Using Franz diffusion cells mounted with a synthetic cellulose membrane (MWCO 12,000), drug release characteristics of the formulations were evaluated by the HPLC assay of KA concentration in the receptor compartment of pH 7.4 phosphate buffered saline solutions. Drug release from w/o/w multiple emulsion cream was controlled by oil membrane, showing the apparent zero order release kinetics. The KA release from the poloxamer gels was also controlled by the gel matrix, showing that drug release increased linearly as KA contents increase, but decreased exponentially as the polymer contents increase. In the skin irritancy test, the primary irritancy index(PII) of poloxamer gel base was lower than those of multiple emulsion cream base and o/w cream. Depending on KA contents or polymer contents in the gel. PH values in poloxamer gels were ranged from 1.3 to 2.0, which are interpreted as low or negligible irritation on skin. There was a good correlation between the log value of flux in drug release and PII value in skin irritation. It was possible to conclude that the poloxamer gels containing KA might be a good candidate for an antimelanogenic topical delivery system by virtue of the controlled release of the drug and the reduced skin irritancy.

Purpose : To shorten processing time for variety of medical affairs of the patient at the outpatient clinic of a big hospital is very important to qualify medical care of the patient. Therefore, patient's waiting time for drug delivery after doctor's prescription is often utilized as a strong tool to evaluate patient satisfaction with a medical care provided. We performed this study to investigate factors influencing patient satisfaction related with waiting time for drug delivery. Methods : The data were collected from July 21 to August 12, 1998. A total 535 patients or their families who visited outpatient clinics of Inha University Hospital were subjected to evaluate the drug delivery time and the level of their satisfaction related, which were compared with those objectively evaluated by Quality Improvement Team. The reliability of the scale was tested with Cronbach's alpha, and the data were analyzed using frequency, t-test, ANOVA, correlation analysis and multiple regression. Results : The mean drug delivery time subjectively evaluated by the patient (16.1 13.0 min) was longer than that objectively evaluated (10.9 7.6 min) by 5.2 min. Drug delivery time objectively evaluated was influenced by the prescription contents, total amount or type of drug dispensed, etc, as expected. The time discrepancy between two evaluations was influenced by several causative factors. One of those proved to be a patient's late response to the information from the pharmacy which the drug is ready to deliver. Interestingly, this discrepancy was found to be more prominent especially when waiting place for drug delivery was not less crowded. Other factors, pharmaceutical counseling at the pharmacy, emotional status or behavior of a patient while he waits for the medicine, were also found to influence the time subjectively evaluated. Regarding the degree of patient satisfaction with the drug delivery, majority of patients accepted drug delivery time with less than 10 min. It was also found to be influenced by emotional status of the patient as well as kindness or activity of pharmaceutical counselor. Conclusion : The results show that, besides prescription contents, behavior pattern or emotional status of a patient, environment of the waiting place, and quality of pharmaceutical counseling at the pharmacy, may influence the patient's subjective evaluation of waiting time for drug delivery and his satisfaction related with the service in the big hospital. In order to improve patient satisfaction related with waiting time for drug delivery, it will be cost effective to qualify pharmaceutical counseling and information system at the drug delivery site or waiting place rather than to shorten the real processing time within the pharmacy.
The purpose of this study was to analyze the relationship between maternal attachment and discharge against advice in high risk infants and determine the factors which affect discharge against advice. Data of this study were collected by means of reviewing the medical records of 127 in-patients who were diagnosed as high risk infants in admission and interviewing of the mothers of these patients was done by telephone. The high risk categories were neonatal hyperbilirubinemia, congenital anomaly, congenital heart disease, blood disorder, neonatal infection and birth injury. Maternal attachment was measured by deviding the subjects into 2 groups, the one the continuing treatment group and the other the discharge against advice group. Maternal attachment is determined by an interplay of maternal attitude and specific infant behaviors. Maternal attachment developes through continuous physical and psychological contact between mother and infants. Later it developes into maternal love. The results were as follows: 1. There was a significant association between maternal attachment and discharge against advice, that is, the attachment score was higher in the continuing treatment group. 2. Inspite of controlling medical insurance, severity of disease and the length of stay, it was found that there continued to be either a partially significant or fully significant relationship between maternal attachment and discharge against advice. Stepwise multiple regression revealed that maternal attachment was second in importance as a predictor of discharge against advice, which indicates that maternal attachment was a significant predictor of discharge against advice. 3. Stepwise multiple regression revealed that in 32.3% of these cases the significant predictors of discharge against advice were length of stay, maternal attachment, delivery type, feeding type and income.
A promising approach to the development of a new single-step vaccine, which would eliminate the requirement for multiple injections, involves the encapsulation of antigens into microspheres. Biodegradable poly(lactide-co-glycolide) (PLGA) microspheres gave us a bright insight for controling antigen release in a pulsatile fashion, thereby mimicking two or tree boosting injections. However, in spite of the above merits, the level of immunization induced by a single-shot vaccination is often lower tan two doses of alum-adsorbed antigen. Therefore, optima modification of the microsphere is essential for the development of single-step vaccines. In the review, we discuss the stability of antigen in microsphere, safety and non-toxic in human and encapsulation technology. Also, we attempted to outline relevant physicochemical properties on the immunogenicity of microsphere vaccine and attainment of pulsatile release pater by combination of different microsphere, as well as to analyze immunological data associated with antigen delivery by microsphere. Although a lot of variables are related to the optimized microsphere formulation, we could conclude that judicious choice of proper polymer type, adjustment of particles size, and appropriate immunization protocol along with a suitable adjuvant might be a crucial factor for the generation of long-lasting immune response from a single-step vaccine formulation employing PLGA microsphere.

As the world gradually advances to an aging society, the quality of human life is valued. Among them, 'quality of sleep' is very closely related to quality of life. Recently, Korea expanded health insurance coverage for "sleep disorders". Particularly, as the number of sleep multiple tests and prescriptions for sleep aids has increased rapidly, much attention has been focused on the related medical service environment. Therefore, this study looked at an in-depth interview of 11 hospitals to see what treatment delivery system is being established when the government applies health insurance for 'sleep disorders'. In conclusion, the organizations with the most average number of sleep polyp tests per day were found to have more sleep polyp labs (hardware) and more full-time specialists. Also, the polysomnography lab (hardware) and the specialist's full-time status (software) did not necessarily result in a "positive pressure regulator prescription" that can solve "sleep apnea" caused by "sleep ailments". Rather, it was found that the number of days of sleep multiple laboratories (hardware), the number of full-time specialists (software) or the specialty majors (software) had a greater impact. In particular, the higher the specialist's full-time personnel (software) index (=6.000), the higher the sleep-inducing agent prescription rate(=1.000), and the lower the specialist's full-time personnel (software) index (=1.000), the higher the sleep-inducer's prescription rate(= 0.010) Was low. In addition, even if the professional full-time personnel(software) index was the same (=1.000), the hospital type was lower as it was closer to the public hospital(=0.067) and higher at the specialized hospital (= 0.933). In the case of university hospitals, when the full-time specialists (software) are in the same condition (= 1.000), the frequency of use of the sleep laboratory (=1.000) and the sleep test rate (= 1.000) were all the same.
In this study, plant regeneration and Agrobacterium tumefaciens-mediated transformation Kentucky bluegrass(Poa pratensis L.) were evaluated. Three different types of calli were produced depending on the combinations of growth regulators. They were non-friable brown or gray-colored callus (type I), compact, friable and yellow or white-colored callus (typeII), and soft, watery translucent callus with differentiated structure (typeIII). The highest regenerable organogenic callus (typeII) was obtained on the medium containing 1mg/L, 2,4-D and 0.1mg/L BA. Additionally, the production of typeII calli increased significantly when AgNO$_3$ was added to the callus induction and growth medium. The highest frequency of multiple shout formation from typeII callus was obtained on MS medium containing 1mg/L BA and 1mg/L Thidiazuron(TDZ). The organogenic calli(typeII) were inoculated with Agrobacterium tumefaciens strain EHA101 harboring the binary vector pIG121Hm with $\beta$-glucuronidase gene, and various factors were found to influence the transfer-DNA delivery efficiency. The highest transient GUS activity was observed on typeIIcallus. In the present work, we reported the first transient GUS activity of Kentucky bluegrass mediated by Agrobacterium tumefaciens. Our system may contribute to genetic improvement for breed-recalcirtrant grass species, Kentucky bluegrass.
Shirasu-porous-glass (SPG) membrane emulsification is highly attractive in the field of toner industries, foods and drug delivery systems because of its easy control of particle size in micro-scale, narrow size distribution and multiple emulsion. The particle size and morphology of emulsion droplets can be controlled by changing the type of initiators, additives, monomers, crosslinkers and inhibitors in SPG membrane emulsification. In this paper, principles of SPG membrane emulsification, influence of process parameters and industrial applications have been addressed.
