This study is to grope for a plan to increase nurse's autonomy by grasping autonomy degree according to nursing delivery system. The subject of this study are 265 nurses who work for 4 general hospitals in Seoul, and 73 of them work in primary nursing delivery system, 99 of them in team nursing delivery system and 93 of them in functional nursing delivery system. Data collection was done through questionaires from Sep. 1, 1997 to Sep. 30, 1997, and autonomy was measured by Professional Nursing Autonomy Scale developed by Schutzonhofer. Data analysis as inspected with $X^2$ test, ANOVA, and t-test, using SPSS program. The results are as follows : 1. When it comes to the autonomy of all the nurses, mean score was 161.99. Which is medium level, and autonomy degree according to nursing delivery system had no significant differences. 2. There was a significant difference in autonomy degree according to inservice education among the subject's work-related characteristics, and there was no significant difference in autonomy distribution in each grade according to general characteristics although older group, married group, and junior college graduates group showed rather higher trends. 3. Considering each item, questions related to direct nursing such as "Vital sign monitoring", "Nursing rounding", "Withhold contraindicated drug", showed high score in autonomy scores, and long-term and indirect nursing behaviors such as "Nursing administration", "Nursing research", "Follow-up care" and "Educational planning".

The aims of this study were to encapsulate arbutin (AR) in liposome to enhance the skin-whitening activity, and to investigate the effect of liposome formulation on the entrapment efficiency (EE%), skin permeation rate and skin deposition. The liposomes were prepared by a film dispersion method with several different formulations and were separated from the solution by using the gel-filtration method. The physical (size distribution, morphology) and chemical (drug entrapment efficiency, hairless mouse skin permeation and deposition) properties of liposomes were characterized. The entrapment efficiency in all liposome formulations varied between 4.35% and 17.63%, and was dependent on the lipid content. The particle sizes of liposomes were in the range of $179.9{\sim}212.8\;nm$ in all liposome formulations. Although the permeation rate of AR in the liposome formulations decreased compared with AR solution, the deposition amount of AR in the epidermis/dermis layers increased in AR liposomal formulation. These results suggest that liposomal formulation could enhance the skin deposition of hydrophilic skin-whitening agents, thereby enhancing their activities.

Ethanol exerts different effects on hepatic cellular metabolism, depending mainly on the duration of its intake. In the presence of ethanol following an acute load, a number of hepatic functions are inhibited, including lipid oxidation and microsomal drug metabolism. In its early stages, chronic ethanol consumption produces adaptive metabolic changes in the endoplasmic reticulum which result in increased metabolism of ethanol and drugs and accelerated lipoprotein production. Prolongation of ethanol intake may result in injurious hepatic lesions such as alcoholic hepatitis and cirrhosis A number of such metabolic effects of ethanol are directly linked to the two major products of its oxidation; hydrogen and acetaldehyde. The excess hydrogen from ethanol unbalances the liver cell's chemistry. In the presence of excess hydrogen ions the process is turned in a different direction. In this study, it was attempted to observe the effect of ginseng saponins on alcohol Oehydrogenase(ADH), aldehyde dehydrogenase(ALDH) and microsomal ethanol oxidizing system(MEOS) in vivo as well as in vitro. Furthermore, the effect of ginseng saponin on the hydrogen balance in the liver and the hepatic cellular distribution of (1-14C) ethanol, its incorporation into acetaldehyde and lipids was also investigated. It seemed that ginseng saponin stimulated the above enzymes and other related enzymes in ethanol metabolism, resulting in a rapid removal of acetaldehyde and excess hydrogen from the animal body,

Time-temperature indicators (TTI) from three different companies obtained and were attached to food packages materials to evaluate degree of their color change according to storage time and temperature. Five temperature (-10 -5, 0, 5 and 10) was selected to represent standard freezing, refrigerating and room temperature, and evaluated performance by color change based on magnitude of color change and hunter system (L, a, b). Response end point was measured and recorded to find characteristic of each indicator. Comparison and discussion were conducted for accuracy and precision of each time-temperature. More research should be conducted at variable temperature and with various food to determine applicability of TTI on various storage condition.

Purpose: The aim of this study was to define the health problem in the community-dwelling elderly of Korea and to compare differences of CAPs(Client Assessment Protocols) by characteristics. Method: Data was collected by visiting nurse from 556 elderly over 65 years in selected metropolitan areas. To evaluate the functional state of elderly in the community, I used "RAI-MDS HC; Residental Assessment Instrument Minimum Data Set-Home Care(2.0 version)" and established information exchange system among resources, by developing the data into a computer program. Results: The health problem of 'preventive health measures' was the largest(99.6%), and then 'health promotion(85.3%)', 'visual function(75.5%)', 'psychologic drug(68.9%)', 'pain(68.5%)', ‘social function(59.2%)', 'communication disorders(56.2%)', 'environmental assessment(53.2%)', 'depression & anxiety(46.9%)', 'oral health(43.4%)' followed. The number of health problems was average 10.16 in the community-dwelling elderly. Conclusion: The results suggest the need to emphasize the importance of assessment of the health problem of the elderly. We can apply it in the distribution of community resources and the development of service providing programs by figure out the health problem and resource in need for the elderly in the community.

This study was perfomed to examine the distribution of causative agent of piglets diarrhea in eastern Chonnam province from February 1994 to March 1995. The causative agents of diarrhea were examined by bacterial culture test, parasitological test and serological test against PED, TGE and Rota. The 35 isolated E. coli were tested for antibiotic sensitivity. The results obtained were as follows. 1. The incidence of 81 piglets with diarrhea was most prevalent as 39.5% in the age of 2 to 4 weeks, compare to 34.6% in the age of 5 to 8 weeks and 16.0% under 1 weeks and 9.9 % in the age of 9 to 11 weeks after birth. 2. The incidence of 81 piglets diarrhea showed bacterial diarrhea(75.3%), viral diarrhea (35.8%) and parasitological diarrhea(18.5%). When compared the isolation frequency of each etiological agent, enteropathogenic E. coli was most prevalent as 55.5% in bacterial diarrhea, rotavlrus enteritis as 18.5% in viral diarrhea and trichuriasis as 13.6% in parasitological diarrhea. 3. The complicated infection of piglets was most prevalent as 41.7% in rotavirus enteritis with enteropathogenic E coli in 24 complicated piglets diarrhea. 4. In antibiotic sensitivity test, isolates showed moderatly resistance to Tobramycin, Amikacin, Imipenem, Trimethoprim/Sulfamethoxazole, Gentamicin, Ampicillin but sensitivty to Ticarcillin/K. The 30 E. coli isolate showed multiple drug resistances in 3 different antibiotics.

One hundred and eighteen cultures of Gram-negative rods isolated from cases of clinical bovine mastitis during lactation were examined for distribution of specific types, and activity of several antimicrobial agents to the isolates was determined by two-fold tube dilution method employing sterile whole milk as fluid medium. Of the isolates, 59.2% were Escherichia coli. Most of the remaining isolates were Klebsiella pneumoniae and Enterobacter aerogenes. Most Gram-negative rods(89.8%) were isolated from acute local and chronic mastitis. The cases of peracute systemic form with a marked symptoms of toxemia were associated with Escherichia coli and Klebsiella pneumoniae. The minimal lethal concentrations (MLC) of gentamicin and oxolinic acid in sterile whole milk were 16-128 times higher than the MLC obtained in trypticase soy broth (TSB), while the MLC of ampicillin and tetracycline in milk increased 2-4 times compared with TSB. Of the drugs tested, gentamicin was the most active antibiotics with MLC of $100{\mu}g/ml$ in sterile whole milk against all of Gram-negative rods isolated from bovine udder infections.

One hundred and sixty one Escherichia coli strains isolated from 24 swine (11 swine fed with feedstuffs containing 7.5mg/kg of tetracycline and 13 swine not received antibiotic) were studied for the drug resistance and distribution of R factors. About 42 per cent of E. coli strains isolated from pigs of a herd fed with tetracycline (TC)-containing feeds were resistant to TC, streptomycin(SM), sulfisomidine(SA), ampicillin (AP) and kanamycin (KM), alone or in combination thereof, but none of the swine not receiving antibiotic containing feedstuffs excreted E. coli resistant to these drugs, Among resistant strains, 18.2% were found to be singly resistant to TC, whereas 81.8% were resistant to two or more antibiotics. The most common pattern was the triple resistant to TC, SM and SA(30.3%), and follolwed by double ones to TC and SM(24.2%). About one half of resistant strains carried R factors which were tranferable to the recipients by conjugation. In spite of feeding with feedstuffs containing only TC, high incidences of multiple resistance and R factors were observed in the E. coli isolated from these swine.

Many pharmaceutical products are available through prescription (Rx) only status. As a result, access to physicians and insurance coverage play a key role in the use of these products, and therefore may affect the population to whom advertising is targeted at. The movement of pharmaceutical products from prescription (Rx) to Over-the-Counter (OTC), or Rx-to-OTC switch changes the cost of acquiring the drug and therefore may change the incentives manufacturers have at targeting particular population segments. This study examines whether Rx-to-OTC switch changes the frequency and the distribution of who is exposed to pharmaceutical advertising. Using an archive of pharmaceutical advertisements and National Consumer Survey, this study examines how individuals with particular demographic characteristics are exposed to pharmaceutical advertisements before and after drugs are moved from Rx to OTC. The results provide evidence that individual's advertising exposure increases after Rx-to-OTC switch. Moreover, the increase in advertising exposure is greater for the low socioeconomic status (SES) consumers which implies they may get more information about the disease, treatment and product after the Rx-to-OTC switch through advertising. If low SES consumers have more exposure to the advertising after products switched to OTC, then FDA policies regulating this switch should recognize the potential role of advertising providing access to health-related information.
