Everyone has the desire to be well shaped. Modern people in the $21^{st}$ century utilize their external appearance as a tool to express their personalities and social activities for the improvement of cultural life and the acceleration of information transfer. The expression of beauty is a method of communication from the view point of creation in addition to the exchange of meaning & value, and it has become a method of image transfer due to the increased desire for a better appearance. The beauty industry was established in 1948 by the execution of the 1st hairdresser's license test, and has been developed in full scale through the enactment of the public health control act. Therefore, beauty education is currently qualitatively and quantitatively developed, and the educational role of the beauty institute has expanded to include training beauty professionals. Private beauty institutes provide students with beauty related education in preparation for the national technical qualification examinations or private beauty association tests. These beauty education opportunities enable aspiring beauticians to attend various beauty competition events and acquire a sense of accomplishment. The purpose of this study was to determine how the quality of the beauty educational institutes affects the re-registration rate, and to analyze the effect of the beauty educational institutes quality on the intention of re-registrations using a survey. The study results show that variables such as 'lecture satisfaction', 'internal environment satisfaction', 'facility satisfaction', and 'tuition satisfaction' are significantly related to the rate of re-registrations, with 'lectures satisfaction' especially having the largest influence on re-registration.

Objectives: Studies on the geographical differences in mortality tend to use a census population, rather than a registration population, as the denominator of mortality rates in South Korea. However, an administratively determined registration population would be the logical denominator, as the geographical areas for death certificates (numerator) have been determined by the administratively registered residence of the deceased, rather than the actual residence at the time of death. The purpose of this study was to examine the differences in the total number of a district population, and the associated district-specific mortality indicators, when two different measures as a population denominator (census and registration) were used. Methods: Population denominators were obtained from census and registration population data, and the numbers of deaths (numerators) were calculated from raw death certificate data. Sex- and 5-year age-specific numbers for the populations and deaths were used to compute sex- and age-standardized mortality rates (by direct standardization methods) and standardized mortality ratios (by indirect standardization methods). Bland-Altman tests were used to compare district populations and district-specific mortality indicators according to the two different population denominators. Results : In 1995, 9 of 232 (3.9%) districts were not included in the 95% confidence interval (CI) of the population differences. A total of 8 (3.4%) among 234 districts had large differences between their census and registration populations in 2000, which exceeded the 95% CI of the population differences. Most districts (13 of 17) exceeding the 95% CI were rural. The results of the sex- and age-standardized mortality rates showed 15 (6.5%) and 16 (6.8%) districts in 1995 and 2000, respectively, were not included in the 95% CI of the differences in their rates. In addition, the differences in the standardized mortality ratios using the two different population denominators were significantly greater among 14 districts in 1995 and 11 districts in 2002 than the 95% CI. Geographical variations in the mortality indicators, using a registration population, were greater than when using a census population. Conclusion: The use of census population denominators may provide biased geographical mortality indicators. The geographical mortality rates when using registration population denominators are logical, but do not necessarily represent the exact mortality rate of a certain district. The removal of districts with large differences between their census and registration populations or associated mortality indicators should be considered to monitor geographical mortality rates in South Korea.

다변하고 복잡한 현대사회에서 1인 가구, 맞벌이 가구, 노인인구의 증가와 사생활보호의식의 강화 등의 조사환경은 많은 비용과 시간이 소요되는 기존방식의 인구총조사에 변화를 요구하고 있다. 덴마크와 핀란드 등 북유럽 선진통계국가의 행정자료를 활용한 경험사례에 비춰볼 때, 우리나라도 주민등록 행정자료 등을 활용한 등록센서스에 대한 깊은 연구가 필요하다. 행정등록자료에 기반을 둔 등록센서스는 조사비용의 절감과 조사의 정확성, 신속성을 높일 수 있을 뿐만 아니라 행정자료 간 연계를 통해 고급통계를 생산하여 다양한 통계수요에 부응할 수 있을 것이다. 본 연구는 인구총조사 개선뿐만 아니라 앞으로 다가올 정보화시대의 센서스에 대비하기 위해 주민등록 행정자료와 2005년 인구총조사 결과를 연계하여 차이점을 살펴보고 인구총조사에 적용할 수 있는 정책적 제안 및 방향을 제시하였다. 연구방법은 개인의 비밀을 최우선으로 하면서 실증적인 연구가 되기 위해 부산해운대구와 충북 보은군을 대상으로 동일주소 내의 나이, 성별을 매칭값으로 연계성을 살펴보고, 매칭율이 매우 낮게 나타난 지역(충북 보은군 회남면)을 대상으로 인구총조사와 주민등록 행정자료를 직접 비교하는 방법을 사용하였다. 특히 2005년 인구총조사 결과와 비교성을 높이기 위해 주민등록 행정자료를 출생 및 사망, 전출 및 전입 등에 대한 정보를 이용하여 2005년 11월 1일 기준으로 자료를 생성하였다.

National cancer incidence data were utilized to analyze trends in esophageal cancer incidence in China in order to provide basic information for making cancer control strategy. We retrieved and re-sorted valid esophageal cancer incidence data from National Central Cancer Registry Database over 20 years period from 1989 to 2008. Crude incidence and age-standardized incidence rates were calculated for analysis, with annual percent change estimated by Joinpoint software for long term trend analysis. The crude incidence rate of esophageal cancer was found to have remained relatively stable in both urban and rural areas over the 20 year period. Age standardized incidence rate (ASR) in cancer registration areas decreased from 39.5/100,000 in 1989 to 23.0/100,000 in 2008 in all areas (AAPC=-3.3%, 95% CI:-2.8~-3.7). The trend was no change in urban areas and 2.1% average annual decrease observed in rural aras. Before the year of 2000, esophageal cancer incidence rates significant decreased with 2.8% annually and then the rates kept stable. Over 20 years from 1989 to 2008, esophageal cancer age standardized incidence rate in cancer registration areas decreased with time. However, esophageal cancer is still a big issue and efforts for control should be continuously enhanced. Cancer registration is playing an important role in cancer control with the number of registries increasing and data quality improving in China.

Background: Magnetic resonance (MR) image guided radiation therapy system, enables real time MR guided radiotherapy (RT) without additional radiation exposure to patients during treatment. However, MR image lacks electron density information required for dose calculation. Image fusion algorithm with deformable registration between MR and computed tomography (CT) was developed to solve this issue. However, delivered dose may be different due to volumetric changes during image registration process. In this respect, synthetic CT generated from the MR image would provide more accurate information required for the real time RT. Materials and Methods: We analyzed 1,209 MR images from 16 patients who underwent MR guided RT. Structures were divided into five tissue types, air, lung, fat, soft tissue and bone, according to the Hounsfield unit of deformed CT. Using the deep learning model (U-NET model), synthetic CT images were generated from the MR images acquired during RT. This synthetic CT images were compared to deformed CT generated using the deformable registration. Pixel-to-pixel match was conducted to compare the synthetic and deformed CT images. Results and Discussion: In two test image sets, average pixel match rate per section was more than 70% (67.9 to 80.3% and 60.1 to 79%; synthetic CT pixel/deformed planning CT pixel) and the average pixel match rate in the entire patient image set was 69.8%. Conclusion: The synthetic CT generated from the MR images were comparable to deformed CT, suggesting possible use for real time RT. Deep learning model may further improve match rate of synthetic CT with larger MR imaging data.

Objective: To evaluate the clinical impact of using registration software for ablative margin assessment on pre-radiofrequency ablation (RFA) magnetic resonance imaging (MRI) and post-RFA computed tomography (CT) compared with the conventional side-by-side MR-CT visual comparison. Materials and Methods: In this Institutional Review Board-approved prospective study, 68 patients with 88 hepatocellulcar carcinomas (HCCs) who had undergone pre-RFA MRI were enrolled. Informed consent was obtained from all patients. Pre-RFA MRI and post-RFA CT images were analyzed to evaluate the presence of a sufficient safety margin (${\geq}3mm$) in two separate sessions using either side-by-side visual comparison or non-rigid registration software. Patients with an insufficient ablative margin on either one or both methods underwent additional treatment depending on the technical feasibility and patient's condition. Then, ablative margins were re-assessed using both methods. Local tumor progression (LTP) rates were compared between the sufficient and insufficient margin groups in each method. Results: The two methods showed 14.8% (13/88) discordance in estimating sufficient ablative margins. On registration software-assisted inspection, patients with insufficient ablative margins showed a significantly higher 5-year LTP rate than those with sufficient ablative margins (66.7% vs. 27.0%, p = 0.004). However, classification by visual inspection alone did not reveal a significant difference in 5-year LTP between the two groups (28.6% vs. 30.5%, p = 0.79). Conclusion: Registration software provided better ablative margin assessment than did visual inspection in patients with HCCs who had undergone pre-RFA MRI and post-RFA CT for prediction of LTP after RFA and may provide more precise risk stratification of those who are treated with RFA.

본 논문에서는 노이즈를 포함한 채 오버랩 영역이 적은 두 점군을 정합할 때 정확도와 수렴 속도를 향상시키는 알고리즘을 제시한다. 정확도를 높이기 위하여 점군의 기하학 정보를 최대한 활용하며, 정합 단계에서는 노이즈가 포함된 점군에서 오버랩 되는 영역을 적절히 선택하고, 개선된 가속 알고리즘을 사용하여 정합 속도를 향상시킨다. 정확도를 향상시키는 기존의 방법은 노이즈가 많은 점군에 적용할 수 없으므로, 본 논문에서는 정합에 사용되는 영역을 선택하는 것으로써 기존 방법의 문제를 해결하였다. 또한 똑같은 점군쌍에서만 적용되는 가속 알고리즘을 낮은 오버랩의 점군쌍에 적용하였다. 기존의 방법에 간단한 알고리즘을 추가함으로써 서너 배 더 빠른 수렴 속도를 낼 수 있도록 하였다. 결론적으로, 노이즈가 많고 오버랩이 적은 점군쌍의 정합에 있어서 본 논문에서 제시하는 알고리즘을 적용하면 속도와 정확도가 향상되었음을 알 수 있다.
