In this paper, we present a new approach to detect and recognize human face in the image from vision camera equipped on the mobile robot platform. Due to the mobility of camera platform, obtained facial image is small and pose-various. For this condition, new algorithm should cope with these constraints and can detect and recognize face in nearly real time. In detection step, ‘coarse to fine’ detection strategy is used. Firstly, region boundary including face is roughly located by dual ellipse templates of facial color and on this region, the locations of three main facial features- two eyes and mouth-are estimated. For this, simplified facial feature maps using characteristic chrominance are made out and candidate pixels are segmented as eye or mouth pixels group. These candidate facial features are verified whether the length and orientation of feature pairs are suitable for face geometry. In recognition step, pseudo-convex hull area of gray face image is defined which area includes feature triangle connecting two eyes and mouth. And random lattice line set are composed and laid on this convex hull area, and then 2D appearance of this area is represented. From these procedures, facial information of detected face is obtained and face DB images are similarly processed for each person class. Based on facial information of these areas, distance measure of match of lattice lines is calculated and face image is recognized using this measure as a classifier. This proposed detection and recognition algorithms overcome the constraints of previous approach [15], make real-time face detection and recognition possible, and guarantee the correct recognition irregardless of some pose variation of face. The usefulness at mobile robot application is demonstrated.

The purpose of this study was to compare the postoperative stability and relapse according to 2 different fixation methods after bilateral sagittal split ramus osteotomies in mandibular prognathic patients. Tweenty one patients with Class III dental and skeletal malocclusion who were treated with bilateral sagittal split ramus osteotomy were selected for this retrospective study. We classfied the patients into two groups according to the fixation methods of bony segments after osteotomies. Group W (n = 10) had the bone segments fixed with nonrigid wire and Group S (n = 11) had bicortical screws inserted in the gonial area through a transcutaneous approach. Cephalometric radiographs were taken preoperatively, immediate postoperatively and more than six months postoperatively in each patient. After tracing the cephalometric radiographs, various parameters were measured. Before surgery, both groups were balanced with respect to linear and angular measurements of craniofacial morphology. Mean posterior sagittal setback amounts of the mandibular symphysis was 8.6 mm in the wire group and 6.79 mm in the rigid group, Six months postoperatively, the wire group had 33.1% relapse of the mandibular symphysis and 22.8% in the rigid group relapse. Both groups experienced changes in the orientation and configuration of the mandible. It is thought that Rigid screw fixation is a more stable method than nonrigid wire fixation for maintaining mandibular setback after sagittal split ramus osteotomy.

본 연구는 동적 베이스 망을 이용하여, 사람의 보행 동작을 보행 방향과 보행 자세로 분리하여 계층적으로 분석하는 방법을 제안한다. DBN의 일종인 FHMM을 기본 바탕으로 하여, 걸음걸이 동작 특성을 고려하여 순환 고리형 상태 공간 구조로 '보행 동작 디코더'(Gait Motion Decoder, GMD)를 설계한다. 기존 연구에는 보행자의 식별에만 치중을 하고 보행 방향의 변화, 관찰 각도에 제한적이거나 보행 동작에 대한 분석이 없었다. 반면에 본 연구에서는 동작과 자세를 적극적으로 표현하여 임의 방향의 보행, 방향의 변화, 보행 자세까지 인식할 수 있도록 하였다. 실험 결과 동작과 자세의 관점에서 걸음걸이 방향을 분석한 결과 96.5%의 방향 인식률을 기록하였다. 본 연구는 보행 동작을 방향과 보행 자세로 계층적으로 분석하는 최초의 방법 및 시도이며 향후 상황별 휴먼 동작 분석에 크게 활용할 수 있을 것이다.

The purpose of this study was to investigate the actual conditions of management of the healthy family field practicum and to present suggestions for its improvement. For this purpose, a preliminary investigation, survey, data analysis, interview as secondary source, and final data analysis were processed as research methods. The subjects of this study were the 42 supervisors in the centers which oversee the field practicum experience and the 12 supervisors in the centers which do not oversee the field practicum experience. 3 supervisors were interviewed to inquire about the reformation of field instruction in Healthy Family Support Centers. Analysis was made of the general characteristics of the above-mentioned 54 supervisors, including sex, age, academic background, certificate of qualification, class of position, and length of career related to the healthy family program. The environment of the field practice, such as the numbers of students supervised, time of field practice, practice hours, and so on, was examined in the centers which oversee the field practicum experience. The actual condition of operation investigated was divided into the preparatory stage, the early stage, the midterm stage, and the end stage. Research was conducted on the improvement of the field practicum, including the proper number of students supervised, adequate practice hours, interaction with universities or colleges, obstacles to the field practicum, and of practicum. The possibility and preparation of a further field practicum was conducted for 12 Healthy Family Support Centers, by inquiring about (a) the reasons for not overseeing the field practicum experience and (b) the needs of universities or colleges for a field practicum. The 54 supervisors surveyed suggested a particular need for improvement in human resources, the space of field instruction, system of field practicum, length of practice hours, orientation for students etc. This study investigated the actual conditions and suggested improvements of the field practicum in Healthy Family Support Centers. Therefore, its results should be meaningfully used to develop the Field Practicum for the Healthy Family and to conduct further studies.

This study aims to present basic materials to promote the importance of make-up design in advertising images and designing effective perfume advertisement by looking at features such as colors, forms, patterns, and material feels, the elements of make-up designs shown magazine advertising images for various perfume brands. The features of make-up designs shown in Anna Sui and Bvlgari perfume advertisements are as the following. Among 9 images in Anna Sui advertisements, 5 displayed mat-like skin feels. Among shadow colors, brown colors accounted for over half, 5 out of 9 while pink colors accounted 5 out of 9 for cheek make-up. Among 7 images in Bvlgari advertisements, pale blue skin colors accounted most, 5 out 7. 4 out of 7 displayed mat-like skin feels and 4 out 7 were in pink colors for lip make-up. Anna Sui brand was found to use a bold and unique makeup design for each perfume advertisement according to the designer's fashion orientation tendency to pursue unique, vintage-style, and romantic images whereas Bvlgari focused on make-up to emphasize elegant and refined female beautify according to the company philosophy of pursuing elegant and high-class images. Namely, it was determined that the BI(brand image), the images a company pursues is related to the MI(make up image), the make-up images in advertisements.

This paper seeks to analyze how the welfare state has developed both in the Kim Young Sam government and in the Kim Dae Jung government. Among other things, the two governments share some similarities: compared to the previous authoritarian governments, both of them enjoyed a high level of democratic legitimacy; the two were under pressure to win the elections to acquire and remain in power; and finally, the two tried to strengthen welfare system. But there exist more critical differences. The Kim Dae Jung government was a minority government, while the Kim Young Sam government was a majority one. Compared to the latter one, the former came to power in an extremely bad economic condition. Fortunately, however, the Kim Dae Jung government was able to enjoy a relatively high level of state autonomy resulting from an exceptional situation of foreign currency crisis. In addition, it was more reformist in policy orientation and had a more open cooperative network with civil society. All these differences added up to produce remarkable differences with regard to the improvement in welfare development. Especially, it is noted that the Kim Dae Jung government was very successful in several respects: provision of national minimum, integration of national medical insurance, development of productive welfare system, and final1y increase in welfare spending. Recently, criticisms from the opposition party, the press, and middle and upper class people mount against the Kim Dae Jung government which has made significant mistakes in instituting the separation of medical and pharmaceutical businesses. However, the important improvements in welfare institutions and programs by the Kim Dae Jung government need to be maintained to deal with all the negative effects of a naked market economy. They must also be sustained to keep alive democracy that Korean people have fought for nearly half a century.

In order to promote and comprehend marriage immigrants' culture, it is essential to understand the life of their families in their counties. For this study, data by a Philippine CFO(Commission on Filipino Overseas) has been analyzed, and the study researcher has attended an educational program run by the PDOS(Pre-Departure Orientation Seminar). Also, in order to understand the immigrants' families in their country, interviews have been done with some of the CFO employees, people arranged to immigrate to Korea through marriage, and female immigrants who are married. First, Filipino females have a positive attitude toward marriage with a foreign male. Most immigrants are from the rural parts of their country, and their families tend to rely on their daughters more than their sons. Therefore, they decide to marry Korean males and immigrate in order to support their families. However many of them do not have enough information about Korea. Second, Philippine's family system is of bilateral kinship, and traditionally, men and women are treated equally. Therefore, Filipino females tend to be well-educated, outgoing, and vibrant. Thus, they can create an active role in married life for themselves and support their family members. Lastly, based on videos and class materials on the topic of domestic violence that are used in the pre-educational programs for females planning to immigrate to Korea, the content of the program is to be revised.
