Background: The outcome of hepatitis B virus (HBV) infection after liver transplantation (LT) was improved by hepatitis B immunoglobulin (HBIG) and nucles(t)ide analogue (NUA). However, HBV recurrence after LT is critical because the recurrence is occasionally accompanied by a progressive destruction of graft and poor survival. The aims of this study were to investigate the significance HBV recurrence and identity factors associated with HBV recurrence. Methods: From October 1999 to February 2011, a total of 2684 consecutive LT recipients who underwent HBV-associated LT were retrospectively enrolled from 7 transplantation centers in Korea. Results: Prophylaxis regimens were HBIG monotherapy (67.7%) or a combination of HBIG with NUA (22.3%). The recurrence rate of HBV was 6.1% (164 recipients) during mean follow-up duration of 10.9 years. The median time from transplantation to recurrence was 2.1 years (0.1-7.9 years). Of the 1,071 patients with hepatocellular carcinoma (HCC) prior to LT, 155 patients (14.5%) had HCC recurrence after transplantation, and 48 patients (31.0%) had HBV recurrence. Of the 48 patients with recurrence of both HBV and HCC, 25 patients (52.1%) experienced HBV recurrence after HCC recurrence. In the multivariate analysis, pretransplant HCC, pretransplant HBV DNA above 5.5 log copies/mL was independent clinical factors influencing HBV recurrence after LT. The mortality rate among the recipients with HBV recurrence was 34.1% (56 recipients). Mean overall survival was 6.4 years in the HBV-recurrence group and 9.9 years in the HBV-nonrecurrence group (p<0.001). HBV recurrence was not an independent prognostic factor for overall survival. HCC recurrence was the most important factor for overall survival. Conclusions: The overall outcome of LT in HBV-related liver disease was excellent with the current prophylaxis regimen Choon Hyuck David Kwon,8 Suk-Koo Lee8 Pretransplant HBV DNA and HCC were important factors for HBV recurrence. HBV recurrence after LT did not significantly influence on the overall survival without combining of HCC recurrence.

연구논문 : 제주지역 미세먼지의 장기변동 및 농도변화에 관한 국지기상 분석

Long-term variations of PM_{10} and the characteristics of local meteorology related to its concentration changes were analyzed at 4 air quality sites (Ido-dong, Yeon-dong, Donghong-dong, and Gosan) in Jeju during two different periods, such as PI (2001-2006) and PII (2007-2013), over a 13-year period. Overall, the long-term trend of PM_{10} was very slightly downward during the whole study period, while the high PM_{10} concentrations in PII were observed more frequently than those in PI. The concentration variations of PM_{10} during the study period was clarified in correlation between PM_{10} and meteorological variables, e.g. the low (high) PM_{10} concentration with large (small) precipitation or high (low) radiation and in part high PM_{10} concentrations (especially, Donghong-dong and Gosan) with strong wind speed and the westerly/northwesterly winds. This was likely to be caused by the transport effect (from the polluted regions of China) rather than the contribution of local emission sources. The PM_{10} concentrations in “Asian dust” and “Haze” weather types were higher, whereas those in “Precipitation”, “Fog”, and “Thunder and Lighting” weather types were lower. The contribution of long-range transport to the observed PM_{10} levels in the urban center (Ido-dong, Yeon-dong, and Donghong-dong), if estimated by comparison to the data of the background site (Gosan), was found to explain about 80% (on average) of its input.

The learning activities of young children have been frequently accomplished through the prose materials varied in the form and the structure. The probe passages mean the language activities that explain, describe, and tell about the objects and events in several sentences. It is needed the concrete materials and the method of instruction in order that young children understand the abstract and complex informations and concepts in prose. The materials of instruction for young children's prose learning involve the pictures, the actions, and the written language that are similar or identical with the prose contents. Thus it is possible to study the relations between Bruner's three repersentational modes (enactive, iconic, symbolic) and the young children's prose learning. The main purpose of this study was to present the appropriate instruction media and method in young children's prose learning by investigating the effects of the repersentational modes, the area, and the kinds of word on young children's memory of key words in prose learning. And the other purpose was to give the basic information in selecting the words for instruction throuh the comparison of nouns and adjectives. The hypotheses of this study are as follows: Hypothesis 1. The young children win recall key words differently in ages. Hypothesis 2. The young children win recall key words better in the conditions of enactive representation and iconic representation than in the condition of symbolic representation, Hypothesis 3. The five, six, seven-year-olds will recall more nouns than adjectives. Hypothesis 4. There win be the interaction effect of the ages and the representational modes. Hypothesis 5. There win be the interaction effect of the representational modes and the kinds of word. For subjects in this study, a total of 90 children who know the written language and go to the kindergarten and the elementary school in Guang-Ju, Ma-San were randomly assigned to the three experimental conditone (actions, pictures, witten languages). The experimental instruments were the actions, the 10 pictures, and the 10 cards with the written languages, and the tapes with the prose passages by the experts. Stein's(1978) "Albert Gets Caught" was used for this study as in Jung Yeon-Suk'a paper(1986). The datas were colleted by the response test consisted of ten items that were divided to 0. 1. and 2 degrees by the responses. The collected dates were analized by the repeated 3×3×2 (Ages × Rrpesentational Modes × Kinds of Word) ANOVA. The following findings were obtained: First, the hypothesis 1 was accepted [F(2, 81) = 1.09, p<,01]. The seven-year-olds (the second grades) rememberd key words better then the five-year-olds and the six-year-olds. But the differonce between the memory of the five- year-olds and that of the six-year-olds was not. Second, the hypothesis 2 was accepted [F(2, 51) = 5.56, P<.01]. Namely the significant differences among the conditions of the notions, the pictures, and the written languages were. The means of the three conditions were 6.78, 6.98, 5.92. And be the mean of the iconic repersentation mods was highest. Third, the hypothesis 3 was sccepted [F(1,81) = 39.68. P<.01]. This indicates the main effect of the kinds of word. And this mians that the kinds of word affect the prose learning of the five, six, and seven-year-olds. Forth, the hypothesis 4 was rejected. the degrees in the three representational modes were consistent in disregard of ages. Fifth, the hypothesis 5 was accepted [F(2, 81) = 3.01, P<.10]. The young children remembered relatively well key words of adjectives in the iconic representation mode.

Dental caries is the most common oral disease. There are many factors contributing to its development. but complete understanding and prevention are not fully know. However, it is possible to remineralize the early enamel carious lesion by fluoride containing remineralization solution. Recently the pH-cycling model has been used to examine the effect of fluoride solution on remineralization of artificial caries in vitro as it can closely simulate the conditions encountered in vivo within a carefully controlled enviroment.

In the mixture planting ratio of tobacco cultivar Y.S.A. and Hicks were investigated on the variation of the leaf characters under field condition. Planting ratio of the above two cultivar were 100 : 0, 75 : 25, 50 : 50, 25 : 75 and 0 : 100 respectively. The results were summarized as follow. 1.Even though the growth characters of Y.S.A. and Hicks were different, the responses to mixture planting ratio were almost the same. The optimum mixture planting ratio of two cultivar for leaf length and leaf width were within a range of 100 % and 25 %, 2.The order of the mixture planting ratio for increases leaf length and leaf width of two cultivar was 100%>25%>75%>50%. 3.The ratio of leaf length to leaf width increased with 75 % mixture planting ratio, but its decreased lenearly with lower leaf position. Leaf length and leaf width of leaf decreased in relation to decreasing mixture planting ratio, but increaesd below a certain of mixture planting ratio. From theses results, it was concluded that mixture planting ratio with two cultivar is not necessary for a good growth of leaf length, leaf width and leaf area of the tobacco plant.

The purpose of this study lies in developing a local educare information center program used for comprehensive day care service, which can satisfy local desire for daycaring and support a community, together with children of day-care age, their parents, and their homes. Through literature research, desire investigation, and day-care specialists' conferences, the study divided the concept of day-care service into three large indexes-children, parents and homes, and a community. The service area for children includes developmental, individual, and specific desire service; the service area for parents and homes has parental participation, parental counseling, and parental training, home-supporting service; the service area for a community has local public information, local participation, use of local resources, local public service. By the way, all of them are medium indexes, and their organization has required small indexes respectively. According to the concept model of comprehensive day care service, the study selected as a dimension the two places for this program and then developed this program for supporting day-care facilities and also, supporting children, homes and a community. Therefore, the program has consisted of 'Furnishing educare information and counseling', 'Training day-care workers', 'Managing a day-care library', 'Children' education and counseling service', 'Parents' training and counseling service', and 'Inter-local exchange.' And each project has its own concrete program and managerial method.
