Purpose: To analyze results of treating acromioclavicular injuries using clavicle hook plates. Materials and Methods: Between February 2008 and April 2010, 18 patients with acromioclavicular joint injury treated by clavicle hook plates were reviewed. Using the Rockwood classification, 7 dislocations were classified as type III injuries and 11 as type V injuries. Implant removal was done at least 3 months from initial fixation. Simple X-rays were taken for comparing the state of reduction, and clinical outcomes were evaluated by the Korean Shoulder Scoring System and the American Shoulder Elbow Society score. The average follow-up period was 9 months. Results: On weight bearing X-rays, the average coracoclavicular distance showed a 114% increase compared to the contralateral side at the time of injury. It decreased to 23% by the last follow-up. The mean Korean Shoulder Scoring System and the American Shoulder Elbow Society score were 80 and 74 at the last follow-up. Conclusion: The immediate stability these plates provide allows rapid rehabilitation. Clavicle hook plate fixation for acromioclavicular joint dislocation is considered an effective method for ensuring satisfactory results both radiologically and clinically.

The hybrid phenomenon of pronunciation of K-Pop lyrics, which is the diction fusion phenomenon of lyrics, is not a strategic measure for an overseas expansion but a natural formation in the course of history of K-Pop. With the debut of Seo Tai-ji and Boys in 1992, the course of K-Pop changed and settled from ballad to dance music. After three years, the success of a hip hop dance music, 'Come Back Home', opened up a door to Korean Americans who ascertained the potential competitiveness of a hip hop music in K-Pop market. And the writer insists that such advance of Korean Americans into K-Pop market is the origin of the bilingual usage and diction fusion phenomenon of K-Pop lyrics. Therefore, this research will look into the pronunciation system of Korean and English in order to understand the bilingual pronunciation system shown in the lyrics sung by Korean American hip hop singers in the 1990s. Moreover, through Korean pronunciation system, this analysis will discover the main cause of continual acceptance and application of Korean American's broken Korean in the diction of lyrics. Last but not least, this exploration will show the correlation of English pronunciation method of Korean lyrics appeared in K-Pop and the diction of Korean lyrics used by Korean American hip hop singers in late 90s. This research will identify the primary cause of the diction fusion phenomenon in the course of history of K-Pop.

The seasonal adjustment is an essential process in analyzing the time series of economy and business. There are various methods to adjust seasonal effect such as moving average, extrapolation, smoothing and X11. One of the powerful adjustment methods is X11-ARIMA Model which is popularly used in Korea. This method was delivered from Canada. However, this model has been developed to be appropriate for Canadian and American environment. Therefore, we need to review whether the Xl1-ARIMA Model could be used properly in Korea. In this study, we have applied the method to the annual sales of refrigerator sales in A electronic company. We appreciated the adjustment by result analyzing the time series components such as seasonal component, trend-cycle component, and irregular component, with the proposed method.

This study compares two teaching methods in an introductory statistics course at a large state university. The first method is the traditional lecture-based approach. The second method implements a flipped classroom that incorporates the recommendations of the American Statistical Association's Guidelines for Assessment and Instruction in Statistics Education (GAISE) College Report. We compare these two methods, based on student performance, illustrate the procedures of the flipped pedagogy, and discuss the impact of aligning our course to current guidelines for teaching statistics at the college level. Results show that students in the flipped class performed better than students in traditional delivery. Student questionnaire responses also indicate that students in flipped delivery aligned with the GAISE recommendations have built a productive mindset in statistics.

The biodegradable characteristics of poly-$\beta$-hydroxybutyrate(PHB) film by fun맥 and soil burial are Investigated. As the results of the American Standards for Testing and Materials(ASTM) method, the you of Aspergillus niger was apparent on the PHB containing plate. This suggests that PHB was utilized as the sole carbon source by Aspergillus niger and ASTM method may have applications as measuring means of biome gradability of polyhydroxyalkanoic acid(PHA). PHB film was studied by monitoring the time-dependant changes in weight loss of PHB film under 30% and relative humidity 80 % during pot-test. As the results of pot-test, PHB film was decomposed about 87 % in 30 days by soul microorganisms. PHB film was more slowly degraded than PHB/HV film.

A modern architectural building is a cultural heritage, which is also part of our history until the present. Documentation is thus considered an irreplaceable method to preserve our cultural heritage as it may be the last resort of preservation. The study analyzed the Historic American Buildings Survey (HABS) on the Heritage Documentation Programs of the National Park Service. Based on the analysis of the comparison and documentation of the modern architectural building implemented by the Cultural Heritage Administration, the study suggested improvement plans from three different perspectives. First, specifically detailed regulations of the legal system are supposed to be used for the implementation of the documentation of modern architectural buildings. Second, it is suggested that a general plan for continuous documentation be made. Last, by setting up a collection method, an information service needs to be provided for the public.

Western missionary nurses practiced in Korea from 1891. and the first trial to begin missionary public health nursing service in 1909 could not put into practice for short of nursing staff and budget. The main focus of missionary medical practice was not in public health program but in the management of missionary hospitals. A few of missionary western R.N. tried district nursing in 1910s. but their activities were personal and focused on the rescue of poor and sick patients. In 1917 the North American Methodist Church dispatched R.N. Elizabeth S. Roberts to begin district nursing in Korea. Roberts began maternal and child district nursing service. Her service was focused on teaching the method of bringing up children. bathing service, and home visiting for delivery. She could not but stop district-nursing service in 1918 to serve for a hospital in Siberia. The North American Methodist Church dispatched a few of R.N. to Korea in early 1920s and the missionary public health nursing of Korea could be activated. R.N. E. T. Rosenberger began public health nursing program in Seoul with Korean graduate nurse, Shin-gwang Han, and missionary M.D. Hall. Their public health nursing program was focused on maternal and childcare. They did home visiting in the morning, and served at a well baby clinic in the afternoon. The first baby competition began in 1925. and contributed to the teaching the method of bringing up children. They expanded public health nursing activity to school health nursing and milk station. Their public health nursing program was such a success that In 1929 Severance hospital. Eastgate Hospital. Taehwa Social Evangelistic center organized Seoul Child Health Union. Maren P. Bording, another missionary R.N. and midwife dispatched by the North American Methodist Church began public health nursing program at Kongjoo in 1924. Her program was focused on the maternal and childcare and close to that of Seoul. She started the first milk station in Korea in 1926. As she was a midwife and could get M. D. license in Korea, her program was more focused on maternal care than that of Seoul. The first day nursery school in Korea and the first graduate course for public health nursing in Korea began at Kongjoo in 1930. As the city of Choongcheongnam Province moved from Kongjoo to Daejeon in 1932, missionary public health nursing service in Kongjoo extended to Daejeon. There were lots of public health nursing program in Korea in 1920s and 1930s by missionary western nurses and Korean nurses. There were 13 missionary public health-nursing center in Korea in 1932. But in the late 1930s. Japan extended colonial war and drove out western missionaries. The missionary service in Korea was daunted. and the missionary public health nursing service could not but shrink.

Purpose: Recommendation for regular Pap test in the past 3 years as a cue to action affects on an increased likelihood of receiving a cervical cancer screening in that period. This study performed to estimate the association with healthcare access, healthcare provider status, and physician recommendation for Pap test in the past 3 years among Korean American women. Method: Korean Health survey was carried out in 2002. These population-based telephone surveys were conducted with Korean American women who resided in Alameda and Santa Clara Counties, California (n=865). We preformed multiple logistic regression analyses to estimate predictors of physician recommendation for Pap test by SAS 8.2. Results: Korean women in two California Counties were 37.9% who received physician recommendation for Pap test in the past 3 years. The predictors on physician recommendation for Pap test in the past 3 years were health insurance coverage, visiting number to doctor in the past year, and healthcare provider status. For healthcare access, no matter who had enrolled in public or private health insurances, the women were more likely to get the recommendation for Pap test from their regular healthcare provider. Particularly, for ethnicity of healthcare provider, the women were more likely to get the recommendation for Pap test from non-Korean female doctors (OR=6.21, 95% CI=2.63, 14.66), Korean male doctors (OR=2.19, 95% CI=1.30, 3.68), and non-Korean male doctors (OR=2.07, 95% CI=1.15, 3.71). Conclusion: (삭제) Effect of healthcare access and healthcare provider status on recommendation for Pap test among Korean American women in two California Counties would contribute to our understanding of developing strategies to promote adherence of Pap test and reduce morbidity and mortality far cervical cancer among Korean American women in the U.S.
