The structure change in the broiler industry of Korea has been taking place very rapidly toward the direction of integrated production and marketing system. During the course of the evolution into the integrated structure, however, a number of small business entities, uncountable nationally but a minimum of a dozen, that previously engaged in the supply of production factors or live bird transaction also tended to get involved in the new system as a disguised or pseudo-integrator, having brought a lot of problems not only to the farmers but also to the development of integrated structure. The pseudo-integrator is generally characterized by limited functions in such a way of supplying chicks and feeds to and collecting grown birds from farmers under the contract at a fixed farmer's payment in practically the same pattern as a partial or quasi-integration, which intends to act as if an integrator in a stratagem to simply enjoy a margin simply from selling supplies and buying products for a certain period of time. The grower making a contract with appears to be a farmer who used to be an Independent and speculating but not able to join in the normal system of evolving integration. The problems of a pseudo-integrator center on the financial loss to a contract farmer, because the falsified integrator has to become easily bankrupt and run away when the price of live broiler continually stays below the cost of production, even though he is able to make a tremendous profit otherwise which is the real purpose of the operation for. It is true that the volatile market, fluctuating the price up more than doubled in a month and down to a half in a few weeks, makes the pseudo-integrator find the room for such a fraudulence. In addition, its activity also adversely affect the evolution of the integration due to rather negative image on structure change in general. It is recommended that the farmers need to better understand the real picture of the integrated system so as not to be swindled by a disguised, small scale agribusiness agent. By the same token, it is also equally required to have the whole industry integrated completely as early as possible. The Joint effort to get rid of pseudo-integrators' problems shall be put for the industry development moving toward the integration. No doubt a pseudo-integrator must be a temporary player for chance emerging during the course of structure change into the integrated, though.

Three major hospitals with over 500 beds located in and near Seoul were surveyed for airbone microorganisms from February 1, 1998 to February 18, 1998. The purpose of the study was to identify and quantify microbiological organisms circulating in the air of three different areas in the hospitals. For the study, a RCS air sampler was utilized equipped with two different collection media, the agar strip GK-A for bacteria and the agar strip HS for fungi. The areas investigated were the intensive care unit (ICU) in the Department of internal medicine, the Newborns room in the Department of Obstetrics, and the microbiology laboratory. The results were as follows; 1. The average numbers of general microbiological particles collected on the agar strip GK-A media were $205CFU/m^3$, $232CFU/m^3$, and $128CFU/m^3$ in each hospitals. The highest concentration of $387CFU/m^3$ was found in the ICU of A hospital at 15:00 during the day. Further analysis of the collected bioaerosols by gram staining, revealed that there were gram positive cocci (89.5%), gram positive bacilli (7.2%), gram negative bacilli (2.8%), and fungi (0.5%), in descending order of frequency. 2. Ten different genes were identified from the agar strip GK-A. The most frequently identified organisms were: the Coagulase negative staphylococcus (55.0%), Micrococcus (21.4%), Enterococcus species(10.4%), and Bacillus species (7.2%). A series of antibiotics susceptibility test were conducted against the aforementioned four(4) organisms. Ninety percent of coagulase negative stapylococcus were sensitive to Penicillins. Pathogenic microbes isolated include: Staphylococcus aureus, Acinetobacter species, Klebsiella pneumonia, Klebsiella oxytoca, and Pseudomonas aeroginosa. 3 Although 56.8% of the microorganisms grown on the strip HS media for fungi could not be identified, some of them were successfully identified. The most frequently found fungi were Aspergillus (35.3%), Yeast or Molds (6.2%), and Penicillium (0.7%). Based on the results obtained from the study, it was concluded that some areas in the hospitals had abnormally high bioaerosol concentrations which could be attributed to human activity. Therefore, it is recommended that periodic assessments of indoor bioaerosols aiming to identify the possible sources should be conducted in order to maintain clean indoor environment in the hospitals.

Purpose : In this study, we tried to know that how the occupational therapists applied the core principles of Ayres's sensory integration(ASI) intervention for clients by using the method of self-assessment. Methods : The study period was from May 2010 to June 2010. The subjects were therapists who use a sensory integration intervention. We letted them to do self-assessment about degree of performing the treatment according to the core principles of ASI by using a questionnaire. Total 66 questionnaires were collected. SPSS for Windows version 15.0 was statistically analyzed. Results : There wasn't anybody without considering the 10 core principles of ASI interventions for children. Therapist's answer(more than 90%) was sometimes, often, always except for the guide self-organization in the 10 core principles of ASI intervention. On the basis of total average score of raw score of 10 core principles of ASI intervention, provide sensory opportunities, provide just-right challenges, collaborate on activity choice, maximize child's success, ensure physical safety, and foster therapeutic alliance showed more than 50 points(T value). The guide self-organization, support optimal arousal, create play context, and arrange room to engage child showed less than 50 points T value. Conclusion : The most effective interventions for sensory integration is the treatment based on the core principles of ASI intervention. According to core principle of ASI intervention, checking the quality of care and increasing the quality of care is needed through performing self-assessment.

I have practiced this reserch for the purpose of proposition of basic data for amendment and addition of computer system after I surveyed the degree of abilities and satisfaction on the computerization in nursing\ practice. Subjects were collected from September 1 to September 30, 1998. Study subjects are 151 clinical nurses who are working at university hospital in Chonbuk area. Study instrument consists of 116 questionnaire which was developed by Kim H. K(1998). The data were analized number, mean ,t-test, ANOVA by using SPSS. The study results are as follows: 1. Most of the nurses who answered the questions were educated computerizing(96%). The abilities of computer program utilities were the most in inputting data(74%). The program nurses wanted computerizing education was wordprocess, dealing internet and statistics. 2. As for applying parts of computer system in nursing, the most nurses were Dr's order check (96%), treatment activity(91.4%), medication(89.4%), lab. test(87 .4%), transfering department(85.4%), transfering room(79.5%), diet(71.8%), discharge (70.2%), Barcord Sticker(70.2%) , reservation(62.2%) in order that were all conected order system mutually to other part. It showed that computer system was not applied for treating the original nursing work such as nursing record (13%), duty scheduling(6.0%) , nursing process(4.6%) , Q.I(1.3%), nursing research(1.3%), education(1.3%), 3. As for the benefit when computer system is applied for, the most respondence was promptness of work and convenience(90.6%) , exactness of work (82.8%), offering information exactily and efficiently(36.3%), offering good quality of nursing (6.0%) in order. 4. The degree of contentment on computerizing in nursing practice showed average 3.24%. The best marking item is that they are eager to participate in the computer education. Next, the automatic output of label and giving the number automatically is to prevent loss and mentioned items of patient registration from being changed(3.95) and to prevent mistakes possibly happening because of doctor's difficult order(3.85). 5. The problems which may happen to in nurses' utilization of computerization for the nursing practice showed average 3.18. The most problem is that the practice may stop because of the problem of computer itself(3.67), and the next, the indication of act can be imperfect(3.66) , manual training may overlap because of incomplete computerization (3.60), practical education for the computerizing is lack(3.41), and the computer literate nurses are lack(3.40) . 6. Study subject's contentment by age was significant difference(F=3.10,P=0.0119). Study subject's contentment by job posision was significant difference(F=6.001P=0.0034) I will propose the following according to the above results. The domain of original nursing practice is urgernt. Manual and indication of act should be made before long in computer obstacle. Nursing department should support the nurses so that they could receive the education needed for the nurses themselves.

A series of catalysts, $NiO-ZrO_2/WO_3$, for ethylene dimerization were prepared by coprecipitation from a solution of nickel chloride - zirconium oxychloride mixture followed by dry impregnation with an aqueous solution of ammonium metatungstate and calcination in air. On the basis of the results obtained from x-ray diffraction and DSC, the addition of NiO and $WO_3$ to $ZrO_2$ shifted the transition of $ZrO_2$ from amorphous to a tetragonal phase toward higher temperatures due to the interaction between NiO(or $WO_3$) and $ZrO_2$. $NiO-ZrO_2$ without $WO_3$ was inactive for the ethylene dimerization, but $NiO-ZrO_2/WO_3$ was found to be very active even at room temperature. The high catalytic activity of $NiO-ZrO_2/WO_3$ was closely correlated with the increase of acid strength by the inductive effect of $WO_3$.

Each 3 g of five different commercial Gal Geun Tang extractive granules was mixed with 97 $m\ell$ of methanol or water for 1.5 hour at room temperature and filtered through a Whatman No. 1 filter paper, and the filtrate was used to determine antioxidant activity. Antioxidative abilities of each extracts were compared by measuring total phenol content (TPC), electron donating ability (EDA), inhibition of lipid peroxidation, and reducing power Average TPC of methanol extracts from five samples was 0.14 mM within the range of 0.07~0.23 mM, while that of water extracts was 0.23 mM, higher than that of methanol extracts. Average EDA of the methanol extracts was 85.54%, higher than that of the 0.1% BHT (72.26%). Average EDA values of the water extracts were 69.7%. Average value of inhibition against lipid peroxidation of the methanol extracts was 26.95%, and the range of five samples was 17.02~37.36%. Inhibition against lipid peroxidation of the water extracts showed relatively low value, 18.62%. Reducing power of the methanol extracts was 0.77 unit, which was 73.1% of 0.1% BHT, and that of water extracts was 0.88 unit. These results indicate that commercial Gal Geun Tang shows high antioxidant ability, though there are some differences depending on extract solvent and manufacturing company.

As one trials to utilize sea mussel and anchovy effectively, powdered instant soups were prepared and then their quality stability were examined during storage. Powdered instant soup was made by adding $3\%$ sugar, $20\%$ table salt, $5\%$ monosodium glutamate, $0.2\%$ black pepper and garlic powder to the pulverized dried sea mussel or anchovy. Powdered instant soup products, powderd products, and dried round state sea mussel or anchovy were packed with air in laminated film bag (cellophane/polyester/aluminium foil/polyester: $20{\mu}m/15{\mu}m/7{\mu}m/20{\mu}m,\;13{\times}14cm$). The contents of amino-nitrogen and volatile basic nitrogen of these products were showed little significant variations and also water activity and color value (L, a, b) of these products were little changed during storage. Thiobarbituric acid value increased up to 30 days of storage and then decreased slightly. Comparing the quality of powdered-seasoned products with that of dried round state products, there were no significant differences in stability during storage. Judging from the experimental results, the quality of powdered instant soup of sea mussel and anchovy were stable for 100 days at room temperature($25{\pm}3^{\circ}C$).

This study aimed to investigate the stability and biological activities of BHSST decoction depending on the preservation temperature and periods. Methods: BHSST decoction was preserved at room temperatures (R/T, $23{\pm}1^{\circ}C$) or refrigeration ($4^{\circ}C$) for 0, 30, 60 and 90 days. To evaluate the stability of BHSST decoction, pH and sugar content were estimated. In addition, high-performance liquid chromatography (HPLC) analysis was performed to determine marker compounds of BHSST decoction. To evaluate anti-inflammatory effect, nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) productions were measured in LPS-stimulated RAW 264.7 macrophages. Antioxidant activity was examined using the assays for 3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) and 1-1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities. Results: There was no change in pH and sugar content depending on the preservation temperature and periods of BHSST decoction. Among the major components of BHSST, contents of liquiritin, baicalein and wogonin was reduced time-dependently both at R/T and $4^{\circ}C$. Inhibitory effects of BHSST decoction on NO and PGE2 productions were slightly decreased in a time-dependent manner by 90 days of preservation. In addition, BHSST decoction maintained ABTS and DPPH radical scavenging activities by 60 days while significantly reducing the activities in 90 days of preservation at R/T. By contrast, BHSST decoction had no significant change of ABTS and DPPH radical scavenging activities by 90 days at $4^{\circ}C$. Conclusions: Our results suggest that the stability and efficacy of BHSST decoction are maintained for 60 days at $4^{\circ}C$ rather than R/T.
