The aim of this study was to explore the effects of a computerized review program which was introduced in August 1, 2003, using claims data for acute respiratory infection related diseases. National Health Insurance (NHI) claims data on respiratory infection related diseases before and after the introduction, with six month intervals respectively, were used for the analysis. Clinic was the unit of observation, and clinics with only one physician whose specialty was internal medicine, pediatrics, otorhinolaryngology and family medicine and clinics with a general practitioner were selected. The final sample had 7,637 clinics in total. Indices used to measure practice pattern was prescription rates of antibiotics, prescription rates of injection drug per visit, treatment costs per claim, and total costs per claim. Changes in the number of claims for major disease categories and upcoding index for disease categories were used to measure claiming behavior. Data were analysed using descriptive analysis, t-test for indices changes before and after the introduction, analysis of variance (ANOVA) for practice pattern change for major disease categories, and multiple regression analysis to identify whether new system influenced on provider' practice patterns or not. Prescription of antibiotics, prescription rates of injection drug, treatment costs per claim, and total costs per claim decreased significantly. Results from multiple regression analysis showed that a computerized review system had effects on all the indices measuring behavior. Introduction of the new system had the spillover effects on the provider's behavior in the related disease categories in addition to the effects in the target diseases, but the magnitude of the effects were bigger among the target diseases. Rates of claims for computerized review over total claims for respiratory diseases significantly decreased after the introduction of a computerized review system and rates of claims for non target diseases increased, which was also statistically significant. Distribution of the number of claims by disease categories after the introduction of a computerized review system changed so as to increase the costs per claims. Analysis of upcoding index showed index for 'other acute lower respiratory infection (J20-22)', which was included in the review target, decreased and 'otitis media (H65, H66)', which was not included in the review target, increase. Factors affecting provider's practice patterns should be taken into consideration when policies on claims review method and behavior changes. It is critical to include strategies to decrease the variations among providers.
Since the Web 2.0 generation, the average user is more than just enjoying the various media contents; they start to create contents, and those contents have had a huge value and great influence in recent days. The reason for the increase of users who tend to create contents is due to popularization of web based applications. Previous applications were only for the skilled person; however, new web based applications involve the average person and give him a new level of user enjoyment by allowing him to create easily with simple operations. In this paper, through analysing previous animation-creating applications which could not spread widely compared to other contents, we suggest the outline for developing a web based animation-creating application which can help the user to easily create animation contents. We have looked around at how various other contents-making applications have been changed to help the user to be able to participate in creating contents, and we suggest how animation-creating applications can be changed and developed from this analysis. We expect the conclusion of this paper to stimulate to development acting 3D animation-creating applications corresponding to the web 2.0 features - open, share, cooperate, participate. In result, users can enjoy creating the animation more actively; at the same time, we hope to help the development of the new applications which correlate to memedia generation.
The culture conditions to maximize the production of endoglucanase (EC 3.2.1.4) from the brown rot fungus Fomitopsis pinicola MKACC 54347 mycelia were investigated. Among the tested media for endoglucanase production, Mandel's mineral salts medium (MSM; 1% cellulose, 0.1% peptone, 0.14% $(NH_4)_2SO_4$, 0.03% urea, 0.2% $KH_2PO_4$, 0.03% $MgSO_4{\cdot}7H_2O$, 0.03% $CaCl_2$, and 0.1% trace metal solution (19.8 mM $FeSO_4$, 13.0 mM $MnSO_4$, 12.2 mM $ZnSO_4$, and 15.4 mM $CoCl_2$)) produced the highest activity of the enzyme. To optimize the medium composition for enzyme activity, the effects of various carbon, nitrogen, phosphorus, and inorganic sources were investigated in MSM. Maximal enzyme production was accomplished using a medium containing 2% carboxymethyl cellulose (CMC), 2% yeast extract, 0.2% $KH_2PO_4$, 0.03% $MnSO_4$, and 0.3% trace metal solution. Different physiological conditions, like incubation period and temperature, were also examined to assess their influence on enzyme production. Enzyme production from F. pinicola reached its highest level after cultivation for 8 days at $25^{\circ}C$. Nondenaturing polyacrylamide gel electrophoresis (PAGE), followed by the endoglucanase activity staining using CMC as the substrate, was performed to identify the endoglucanase under the culture conditions studied. Zymogram analysis of the culture supernatant revealed an endoglucanase band with a molecular mass of 52 kDa. The optimum pH and temperature for enzyme activity were $55^{\circ}C$ and pH 5.0, respectively.

This study investigated the influence of ionic strength on the adhesion and release of bacteria (Escherichia coli, Bacillus subtilis, and Staphylococcus aureus) in quartz and iron-coated sands using column experiments. Results show that the mass recovery remained constant (E. coli = 13.7${\pm}$0.5%, B. subtilis = 9.8${\pm}$1.3%, S. aureus = 13.0${\pm}$2.1%) in iron-coated sand while it decreased from 80.7 to 45.3% (S. aureus) in quartz sand with increasing ionic concentrations from 1 to 100 mM. As the ionic concentrations of leaching solution was lowered from 100 to 0.1 mM, average 39.1% of bacterial detachment was quantified from quartz sand, but no bacterial release was observed in iron-coated sand. The phenomenon observed in iron-coated sand can be attributed to the inner-sphere complexes between bacteria and coated sand, which have minimal effect from ionic strength. This study improves our knowledge regarding the bacterial interaction with surface-modified porous media.

Ammonia oxidizing bacteria(AOB) oxidize ammonia to nitrite and are important microorganisms which control nitrification. Several environmental factors such as dissolved oxygen(DO), temperature and pH influence the growth of AOB. In this work, to assess the effect of DO concentration on AOB, four aerobic biofilm reactors packed with ceramic media were operated 1, 3, 5 and 7 mgDO/L, respectively. The optimal DO concentration with stable nitrification efficiency in aerobic biofilm reactor was above 5.0 mg/L. To assess the relationship between the DO concentration and the characteristics of AOB in aerobic biofiim reactor, DGGE and cloning based on PCR targeting 16S rRNA and amoA gene were performed. Additionally, INT-DHA activity test was proceeded to estimate the activity of AOB. As the results of DGCE and cloning, the community of AOB and the ratio of Nitrosomonas sp. changed little in spite of different nitrification efficiencies. INT-DHA activity test showed that the activity of AOB decreased as DO concentration decreased. It means that DO concentration does not affect the community of AOB, but the activity of AOB.
Splanchnic nerve block (SNB) is performed to relieve intractable upper abdominal pain caused by carcinoma of the upper G-I tract. Not all patients achieve satisfactory pain relief; therefore, a second or third nerve block trial may need to be performed. In this study, an attempt was made to analyze the possible factors which might affect the result of repeated SNB in 42 the patients among 264 patients who received SNB at Severance Hospital during the period from January 1985 to December 1989. The results are as follows: 1) Among the 42 patients, including 30 males and 12 females, the fifties and forties were the major age groups. 2) Among the underlying diseases, stomach cancer was the most common (18 cases) and pancreatic cancer was next (14 cases). 3) The main locations of pain were the upper abdomen, epigastrium and entire abdomen in decreasing order. 4) Among the thirty-nine cases of first SNB combined with ascites, 13 cases received a repeat block, 81.0% of whom had had metastatic lesion. 5) There were 54.2% who had had single or combined treatment, operation, chemotherapy or radiotherapy before SNB. 6) Twently seven cases (64.3%) had received opioid medication for pain control. 7) In the 75% alcohol group, 11.7% of patients required a second block, and in the pure and 50% alcohol group, 9.6% of patients required a second block within two weeks of the first block. Three cases in both of these repeated block groups required a third block; representing 3.9%, of the 75% alcohol group and 1.6% of the pure and 50% alcohol group. 8) The volume of alcohol used was more than 16 ml bilaterally in both cases. 9) The points of the inserted needle were positioned in the upper and anterolateral part of the $L_1$ vertebra on both sides on the anteroposterior roentgenogram. The contrast media was spread upward along the anterior margin of the vertebral body and posteriorly in repeat block. The frequency of repeat block was higher in cases with ascites or metastasis. The instance of repeat block within 2 weeks of the first block was lower in the pure and 50% alcohol group than in the 75% alcohol group. Thus, alcohol concentration and patient status may be considered factors which influence the result of repeated SNB. We suggest early application of SNB in upper abdominal cancer patients.

This study aims at providing basic data on organ donation by analyzing factors of influencing toward intention to organ donation and further at improving people's consciousness on organ donation, subject to citizens of Busan City. The data was collected for 47 days from 14 July to 31 August, 2009. Among a total of 2200 cases of the questionaries, only 2042 cases were used. For data analysis, SPSS 17.0 was used, and for the specific analysis method frequency analysis to understand general characteristics of the participants. In addition, examination on T-test and ANOVA analysis were conducted after analyzing the factors for participants' consciousness on organ donation, and logistic regression analysis for understanding of relations between participants' will to donate organs and general characteristics. The results of this study are summarized as follows; First, among the participants, those who have heard about organ donations were 71.6%. Second, the factors that general characteristics influence on the attitudes towards organ donation include gender, chronic diseases or incurable diseases in the respondents or their family, religion, acceptive attitude factor, exclusive attitude factor and positive attitude factor towards organ donation. Based on the results, in order to raise people's consciousness on organ donation and form social sympathy, more than anything else, public mass media like broadcasting is important. In addition, as organ donation centers and related institutions prepare nationwide events, we should endeavor to prepare the opportunities in various ways to converse people's consciousness on organ donation and further put organ donation into practice.
This descriptive study was done to investigate the proportion of mothers breast feeding and identify factors which influence breast feeding. The subjects were 320 mother who child under five years of age, living in WonJu and their children who numbered 530. Data collection was conducted at various places in the WonJu area using survey questionnaire. The results were as follows : 1. The proportion of children receiving breast feeding was 23.3%, mixed feeding 31.7%, milk feeding 45.1%. The most frequent duration for breast feeding was one month, the mean duration was six months. 2. The major reasons for breast feeding were for the health of the child 52.5%, for emotional attachment with the child 34.2%, and as the expected way of feeding 29.5%. 3. The major reasons for interrupting breast feeding were jobs 26.1%, illness of the child or mother 16.1% abnormality of the breast of nipple 12.7% others 31%. 4. The major reasons for quitting breast feeding were insufficient breast milk 34.5%, job 19.6%, diarrhea in the child 9.9%. 5. The factors influencing breast feeding were educational status and the presence of a job. 6. The husband's attitude to breast feeding was very positive 82.3% and the subjects were supported by their mothers and husbands. But the major information sources about breast feeding were the mass media 30.4% and relatives 22.0%. 7. The breast feeding mother reported experiencing positive and satisfactory feelings, but the milk feeding mother reported experiencing negative and guilt feelings. Also the breast feeding mothers perceived their children as very healthy with a stable emotional status. The results showed the breast feeding ratio in WonJu to be very low and problematic and the subject mothers strongly need information about breast feeding and support while breast feeding. Therefore it is recommended that an education program for community women and other people, like husbands, and grandmothers, be developed along with an education program for university students and other young people to provide them with preparatory information as they begin to think about marriage and families.
Transmedia has become a significant theme in the media studies sector and an academic discourse itself since its wide diffusion through Henry Jenkins' seminar book Convergence Culture. The aim of this essay is to examine the authentic intention of the proposer to understand its profound meaning and value in the research discourse. Firstly, Transmedia has originated as a part of the convergence culture research context, which is an identical approach in the 'active audience' research tradition. Thus, a history of the research in terms of Birmingham Cultural Studies tradition and its implication is scrutinized. Secondly, in respect of Pierre Levy's 'collective intelligence' which made significant influence on the making of the Convergence Culture and Transmedia Storytelling, the meaing of the transmedia discourse is studied. Thirdly and finally, the implication of this concept as a critical theory or Critique in the Cultural Studies tradition, which has highlighted the importance of the revelation of the binary oppositions and structures of dominance/resistance, with the interpretation of the role of the collective intelligence idea in the transmedia discourse, is studied.
The purpose of this paper is to examine the ethical implications in UCC participation. This paper aimed at examining the advent of UCC as a critical media tool in interactive two-way communication and the effect of ethical questions on the level of UCC participation. The findings show that uncertainty avoidance gives an positive and significant effect on privacy concern and regulatory preference, but it is not related to copyright invasion in Korea and U.S.A. It is shown that privacy concern does not influence on UCC retrieval in Korea whereas it is positively related to UCC retrieval in the United States. Also, privacy concern has not relationship with UCC production(modification, recreation, generation) in both nations. In the case of regulatory preference, it posits an significant and positive effect on UCC retrieval in Korea while it is not related to UCC retrieval in the United States. Also, regulatory preference does not affect on UCC production in Korea whereas it influences on UCC generation without impacting UCC modification and recreation in U.S.A. Finally, the results show that copyright invasion has stronger relationship with UCC recreation and generation than UCC modification, and it is positively related to UCC retrieval in both nations.
