This study analyzed the effect of the environment of cooking education institutes on students' study satisfaction and re-registration in Busan, in order to provide those students with good education environment and useful information. The survey was conducted from March 25th to April 11th, 2008. 300 copies of the questionnaire were distributed and 293 copies were returned, among which 270 copies(unsuitable 23 copies were excluded from the analysis) were included as reliable statistical data for analysis. To figure out the result, frequency analysis, reliability verification(Cronbach's Alph), factor analysis and regression analysis were employed in this study. Analyzed factors included cooking environment factor, education service factor, additional factor and lecturer's attitude factor. For the regression analysis to find out the effect of cooking education environment factor on study satisfaction and re-registration, it was found that cooking environment factor, education service factor, additional factor and lecturer's attitude factor had significant effect on study satisfaction and re-registration, which meant that the assumptions 1, 2, 3, 4 and 5 were adopted in this analysis. For the regression analysis to find out the effect of the satisfaction for the environment of cooking education institutes on re-registration, it was found that study satisfaction had significant effects on re-registration and the assumption 6 was adopted. Through this study, it was suggested that the satisfaction and re-registration of cooking education institutes were influenced by all factors, especially for cooking environment and education service. Thus, it is necessary to improve the old environment for cooking education and cooking education programs. Also, continuous study should be conducted to secure potential customers in the future.

In order to reconstruct a full 3D human model in reverse engineering (RE), a 3D scanner needs to be placed arbitrarily around the target model to capture all part of the scanned surface. Then, acquired multiple scans must be registered and merged since each scanned data set taken from different position is just given in its own local co-ordinate system. The goal of the registration is to create a single model by aligning all individual scans. It usually consists of two sub-steps: rough and fine registration. The fine registration process can only be performed after an initial position is approximated through the rough registration. Hence an automated rough registration process is crucial to realize a completely automatic RE system. In this paper an automated rough registration method for aligning multiple scans of complex human face is presented. The proposed method automatically aligns the meshes of different scans with the information of features that are extracted from the estimated principal curvatures of triangular meshes of the human face. Then the roughly aligned scanned data sets are further precisely enhanced with a fine registration step with the recently popular Iterative Closest Point (ICP) algorithm. Some typical examples are presented and discussed to validate the proposed system.

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.

In reverse engineering (RE) sustems, the quality of the data aquisition process is crucial to the accuracy of the reverse engineered three dimensional computer-aided design (CAD) model. However, these tasks are predominantly done manually, and little work has been done to improve the efficiency of scanning by determining the minimum number of scans and the optimal scanning directions. In this paper, new scanning and registration methods using tooling balls are developed to assist in determining the optimal parameter for these processes. When the object to scanned has no concavity, attaching path of the object and its bounding rectangle are used for optimal scanning and registration. Then minimum number of tooling balls and their positions are calculated automatically. In the case of concave parts, the scanning plan should include a complete scan of the concave area. With the surface normal vector and the scanning direction, the minimum degree of rotating the part can be calculated. But the maximum rotation should be restricted in order to prevent occlusion of the part. Finally tow sample part ar scanned based on the proposed methods and the results are discussed.

Background: Cancer has important social consequences with cancer registration as the basis of moving towards prevention. The present study aimed to estimate the completeness of registration of the ten most common cancers in patients referred to selected hospitals in Shiraz, Iran by using capture-recapture method. Materials and Methods: This cross-sectional analytical study was performed in 2014 based on the data of 2009, on a total of 4,388 registered cancer patients. After cleaning data from two sources, using capture-recapture common findings were identified. Then, the percentage of the completeness of cancer registration was estimated using Chapman and Chao methods. Finally, the effects of demographic and treatment variables on the completeness of cancer registration were investigated. Results: The results showed that the percentages of completeness of cancer registration in the selected hospitals of Shiraz were 58.6% and 58.4%, and influenced by different variables. The age group between 40-49 years old was the highest represented and for the age group under 20 years old was the lowest for cancer registration. Breast cancer had the highest registration level and after that, thyroid and lung cancers, while colorectal cancer had the lowest registration level. Conclusions: According to the results, the number of cancers registered was very few and it seems that factors like inadequate knowledge of some doctors, imprecise diagnosis about the types of cancer, incorrectly filled out medical documents, and lack of sufficient accuracy in recording data on the computer cause errors and defects in cancer registration. This suggests a necessity to educate and teach doctors and other medical workers about the methods of documenting information related to cancer and also conduct additional measures to improve the cancer registration system.

이동기술의 발전으로 이동성을 지원하는 멀티캐스트 서비스에 대한 요구가 증가되면서 많은 방법들이 제시되었다. 하지만 기존의 방법들로는 이동노드의 움직임에 따라 멀티캐스트 서비스에 재가입을 하게됨에 따른 지연과 패킷손실이 발생하게 된다. 이러한 패킷손실을 줄이고자 본 논문에서는 지역 등록방법을 이용한 새로운 방법을 제안하였다. 제안한 방법은 기존의 지역등록방법에서 시그널링 메시지 부분을 수정하였으며, 캐쉬 부분을 추가하였다. 동일 GFA내에서 이동시에는 완전하게 등록이 끝날 때까지 이동하기전 FA로의 등록을 유지하며, 다른 GFA내로 이동한 경우에는 캐쉬를 사용함으로써 등록되는 동안 오게되는 패킷손실을 방지한다. 이러한 방법을 통해 이동노드의 움직임에 따른 패킷손실을 줄이게 되어 보다 효과적인 멀티캐스트 서비스를 받게 된다.
