Helicobacter pylori is the major cause of histologic chronic gastritis and is strongly associated with peptic ulcer disease, gastric cancer and lymphoma. Several recommendations for the management of the Helicobacter pylori infection have been developed. However, there has been no clear therapeutic regimen for the optimal treatment of Helicobacter pylori infection. This study was desinged to evaluate the eradication rate and the ulcer healing rate of the triple regimen with low-dose clarithromycin(0.5g/day) in peptic ulcer patients. Forty three patients with gastric ulcer(n=15) and duodenal ulcer(n=28) were enrolled. The patients were treated either with omeprazole 20mg b.i.d. amoxicillin 0.5g b.i.d. and clarithromycin 250mg b.i.d. (low-dose regimen group, n=29) or with omeprazole 20mg b.i.d., amoxicillin 1.0g b.i.d. and clarithromycin 0.5g b.i.d.(high-dose regimen group, n= 14) for 2 weeks. After 4 weeks, the patients were evaluated for the eradication of Helicobacter pylori and the healing of ulcer. And gastritis scores according to the Sydney system were evaluated before and after 4 weeks from the end of the triple regimen. There was no significant difference in the eradication rate and the ulcer healing rate between the low-dose regimen group, group and the high-does regimen group. In the low-does regimen group, the mean initial scores of chronic inflammation and activity were decreased after the eradication of Helicobacter pylori. In conclusion, the low-dose triple regimen is as effective as the high-dose triple regimen on the eradication of Helicobacter pylori and the ulcer healing rate in peptic ulcer disease.

In order to compare the NVOC (Natural Volatile Organic Compound) emission rates from oak trees, the emission rates of isoprene were quantitatively measured in situ based on tree species and region. As a result, the emission rates from Quercus serrata T. were found to be 1000 times greater than those from Quercus acutissima C. However, the emission rates at the Chiri and Gumsung mountain sites did not show any significant differences in summer. Cuvette tests using four different oak species also supported that there was a tremendous difference in emission rates between Quercus serrata T. and Quercus acutissima C. It was found that the emission rates from the trees were highest on the order of Quercus serrata T., Quercus aliena B., Quercus acutissima C. and Quercus variabilis B.

Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.

In handball games, There is a close correlation between the results of games and how defense pattern are effectively changed following the attacks of the opposite following game times. That is, effective attack pattern have important effects on the results of games. This study is examines of the differences in the results of games following defense strategies which greatly influence on the opposite team in handball games. For the study, games of men's professional teams were photographed. Test was executed to examine the frequencies of the pattern and positions bringing marks obtained by the opposite team, which were done by goal keepers, following various defense type of each team and following defense pattern. ANOVA was executed for the pattern and positions bringing marks obtained by the opposite, which were done by goal keepers. In addition, forms and positions bringing marks were obtained by the opposite, which were done by defences, following various defense positions. When there was a difference between team levels, post tests were done and here are the results: 1. Defense abilities in handball games are diverse, following attack pattern, and they are connected directly with game ability. Therefore, defense abilities cannot be neglected. This study shows that according to the levels of games, such as advanced, intermediate, and beginner, defense pattern are different in each team, having various effects on game ability. Thus, developments of various strategies appropriate for teams' characteristics have great influences on game ability. 2. Defense pattern following times are connected directly with the progress of game. The analysis result of defense pattern following times shows that each team keeps fixed defense patterns appropriate for its characteristics. However, the need of a post study is suggested since defense pattern are a little different according to the characteristics of the opposite team on the field.

본 연구에서는 오존의 당일예보모형 2개(중회귀모형, 판별분석모형)를 선정하고 상호 비교·평가함으로써 모형들이 갖는 특성을 대기오염 관리대책에 반영시키기 위한 연구를 수행하였다. 고농도 오존계절의 분석 결과로부터 4월~8월의 5개월(153일)간의 기간을 광화학스모그 발생가능성이 높은 계절로 선정하였고, 오존농도의 일변화 특성은 오전 8시경부터 점점 증가하다가 오후 2~4시경에 최고점에 달하는 것으로 나타났고, 오존농도의 지역특성을 요인분석을 통하여 분석한 결과, 서울시 전체지역(최소한 반경 15km 이내)의 오존농도 변화특성을 하나의 모형으로 설명하는 데 큰 무리가 없음을 알았다. 모형작성 및 검정·검증을 행하고 상호 비교한 결과, 판별분석 모형이 예상했던 바와 같이 임의의 고농도일 만을 주목한 경우에는 중회귀모형 보다 약간 더 좋은 결과를 보여 주었고, 전반적인 경우에는 두 모형이 비슷한 결과를 나타내었다. Based on of analyzing the season of high level of Ox(Oxidant), five months from April to August were selected. As a result of investigating the weather effect on high level of Ox days and the diurnal variation of Ox, it was observed that the temperature was comparatively high, the wind velocity was very low, and the irradiation intensity was very high. It was found that hourly Ox increased from 8 A.M. and reached its peak by 2~4 P.M. As a result of factor analysis, an area characteristic of Ox could be explained by only one model for the whole area of Seoul(at least within 15 km of a radius). It was proved that a discriminant model is better than a multiple regression model in case that a high level of Ox is concerned, but in general two models were alike. Therefore, in view of photochemical Ox control strategy, it is thought that a discriminant model is more useful than a multiple regression model, in case that the excess of a certain warning criteria is important than any other cases.

소나무로부터 직접 배출되는 주요한 모노테르펜 물질로 α-pinene, camphene, myrcene, β -pinene, α-phellandrene, α-terpinene, d-limonene, p-cymene, β-phellandrene 등이 확인되었다. 7년생 소나무에서 직접 배출되는 모노테르펜 물질의 구성비를 분석한 결과 β-pinene이 67.0%로 가장 높았고, 22년생 소나무 경우에 β-phellanone이 37.4%로 가장 높았으며, 32년생 소나무는 α-pinene 구성비가 약 42.9%로 가장 높았다. 소나무는 수령에 따라서 구성비에 큰 차이를 보였으며, 소나무 수령이 높을수록 α-pinene이 구성비가 높았다. 소나무의 수령별 α-pinene과 β-pinene의 비율(α-pinene/β-pinene)을 비교한 결과, 7년생 소나무의 경우 0.16~l.15 범위로 나타났고, 22년생 소나무의 경우 0.64~2.47로 나타났으며, 32년생 소나무의 경우 0.50~18.47 범위로 나타났다. α-pinene과 β-pinene의 비는 수령이 높아질수록 좀 더 높은 값을 보였고, 동일한 수령일지라도 나무에 따라서 차이를 보였다. The major monoterpenes emitted from the Pinus densiflora were α-pinene, camphene, myrcene, β-pinene, α-phellandrene, α-terpinene, d-limonene, p-cymene and β-phellandrene. As a result of comparison of monoterpene composition by tree age for P. densiflora, it was found that β-pinene was a dominant monoterpene for 7-year-old pine(67%). β-Phellandrene(37.4%) and α-pinene(46.1%) were most abound for 22-year-old pine and 32-year-old pine respectively. The ratio of monoterpene composition varied considerably with tree age for the pine, and the percentage of α-pinene composition increased with tree age. The ratio of α-pinene and β-pinene(α-pinene/β-pinene) increased with tree age, and varied tree to tree.

In order to investigate the composition ratio and the emission rate of monoterpenes emitted from coniferous trees during summer, the enclosure chamber experiments were carried out for two tree species (Pinus densiflora and Pinus rigida). The major monoterpenes from the pine trees were α-pinene, β-pinene, myrcene and β-phellan-drene. There was no difference of the composition ratio between two sites for P. densiflora, but the difference was observed for P.rigida, Clearly, the ratio of β-pinene (26.1%) for P.rigida was higher than that of β-phellandrene (12%) at the Gumsung mountain site, but the ratio of β-phellandrene (22.2%) was higher than that of β-pinene (9.9%) at the Chiri mountain site. Particularly, the composition ratio of β-phellandrene was higher than that of β-pinene for P.densiflora, and the opposite trend was found for P.rigida at the Gumsung mountain site. The characteristics of the composition ratio between two species were similar at the Chiri mountain site. As a result of the emission rate measurements, it was observed that both sites did not show any significant β value (slope between emission rate and temperature) and ERs (Standard Emission rate at 30℃) difference. However, the β value and ERs at the Chiri mountain site were slightly greater than those of Gumsung mountain site for both pine species. P.densiflora(1.703 and 1.971㎍C/gdw/hr) showed the higher monoterpene ERs than those of P.rigida (0.572 and 0.698 ㎍C/gdw/hr) at both sites.

Recently, we have successfully developed the chaotic mixing device termed "Chaos Screw" in single-screw extrusion processes. In order to understanding the details of residence tunes, Poincare sections and mixing patterns for Chaos Screw, one has to evaluate the particle trajectories efficiently and accurately over the entire region of the Chaos Screw, which require a tremendous computation time if one simply in tegrates the velocity fields by Runge-Kutta method. The present paper intruduces a new mapping method to determine th particle trajectories efficiently and accurately. With tins new method, the numerical troble can also he circumvented near the wall surfaces. For computational efficiency and accuracy, the proposed method was found to be powerful com pared with the Runge-Kutta method.
