This study introduces a new tool breakage detecting technology comprised of an unsupervised neural network combined with adaptive time series autoregressive(AR) model where parameters are estimated recursively at each sampling instant using a parameter adaptation algorithm based on an RLS(Recursive Least Square). Experiment indicates that AR parameters are good features for tool breakage, therefore it can be detected by tracking the evolution of the AR parameters during milling process. an ART 2(Adaptive Resonance Theory 2) neural network is used for clustering of tool states using these parameters and the network is capable of self organizing without supervised learning. This system operates successfully under the wide range of cutting conditions without a priori knowledge of the process, with fast monitoring time.

The purpose of this study examines the fashion-related concerns of women in their early twenties and their personal thoughts on sociocultural factors through fashion. Data were collected twenty-seven female participants in their twenties in order to examine their traumas related to fashion and how these experiences affect their attitude toward clothing and fashion. Based on this, this study sheds light on what effects traumatic experiences have had on participants' self-esteem. It also provides an in-depth analysis of the problems underlying and reasons for the study participants' fashion choices, and attempts to demonstrate their self-reflection through fashion. Finding of the study was that the participants had a passive attitude toward fashion and built a wall against it. The study results suggest that the very first step to going beyond oneself and developing an active attitude is to try to be proactive and face a challenge related to fashion or clothes that one chooses oneself. Therefore, it is now time for Korean society to shape a culture that respects the unique qualities of every individual and allows free expression of diversity.

Although significant progress has been made in synthesizing visually realistic face images by Generative Adversarial Networks (GANs), there still lacks effective approaches to provide fine-grained control over the generation process for semantic facial attribute editing. In this work, we propose a novel cross channel self-attention based generative adversarial network (CCA-GAN), which weights the importance of multiple channels of features and archives pixel-level feature alignment and conversion, to reduce the impact on irrelevant attributes while editing the target attributes. Evaluation results show that CCA-GAN outperforms state-of-the-art models on the CelebA dataset, reducing Fréchet Inception Distance (FID) and Kernel Inception Distance (KID) by 15~28% and 25~100%, respectively. Furthermore, visualization of generated samples confirms the effect of disentanglement of the proposed model.

In contemporary philosophy, the thinking subject became the dis-constructed subject and there was not left any one center in thinking. On the contrary of this trend, the philosopher Levinas stresses 'an ethics of Otherness' that requires the subject to be responsible for the Other. For Levinas, the Other is not knowable and cannot be made into an object of the self. For Levinas, the irreducible relation, the epiphany, of the face-to-face, the encounter with another, is a privileged phenomenon in which the other person's proximity and distance are both strongly felt. The face of the Other comes toward me with its infinite moral demands while emerging out of the trace. In the movie , when Sachie encounters them, she greets them. She provides them with food and shelter to protect from the dangers of elements. With the help of Sachia, the restaurant becomes a peaceful communal place for her and the Other.

This paper presents a novel approach for facial motion tracking and facial expression cloning to create a realistic facial animation of a 3D avatar. The exact head pose estimation and facial expression tracking are critical issues that must be solved when developing vision-based computer animation. In this paper, we deal with these two problems. The proposed approach consists of two phases: dynamic head pose estimation and facial expression cloning. The dynamic head pose estimation can robustly estimate a 3D head pose from input video images. Given an initial reference template of a face image and the corresponding 3D head pose, the full head motion is recovered by projecting a cylindrical head model onto the face image. It is possible to recover the head pose regardless of light variations and self-occlusion by updating the template dynamically. In the phase of synthesizing the facial expression, the variations of the major facial feature points of the face images are tracked by using optical flow and the variations are retargeted to the 3D face model. At the same time, we exploit the RBF (Radial Basis Function) to deform the local area of the face model around the major feature points. Consequently, facial expression synthesis is done by directly tracking the variations of the major feature points and indirectly estimating the variations of the regional feature points. From the experiments, we can prove that the proposed vision-based facial expression cloning method automatically estimates the 3D head pose and produces realistic 3D facial expressions in real time.

Class III malocclusion usually becomes manifested at a very early age, most typically evidenced clinically by the appearance of either an edge-to-edge incisor relationship or an anterior crossbite. Anterior crossbite, by it-self, retards growth of maxilla, and accelerates growth of mandible. So, treatment should be started as early as the patient cooperates, removing any factors or forces that inhibit growth and development in the same physiologic maxillary displacement direction. The facial mask is effective in most developing Class III patients, because the appliance system affects virtually all areas contributing to a Class III malocclusion. Thus, the facial mask can be applied to most developing Class If cases regardless of the specific etiology. In these cases, the results were followed. Anterior crossbite was corrected by anterior movement of maxilla and downward backward rotation of mandible and simultaneously, lower facial height was increased. So, it can be concluded that the facial mask is effective in treating growing patients with a deficient maxilla.

The purpose of this study was to verify the usefulness of kinetic House- Tree- Person drawing as a diagnostic measure for the degree of self-differentiation, which is an essential part of college students' development. Participants for the study were four hundred thirty five(272 male and 163 female) university freshmen enrolled in 4-year colleges located in Pusan. The Participants completed a scale of self-differentiation and a Kinetic House- Tree-Person drawings test. The evaluation system for kinetic House-Tree-Person drawings was established based on the indexes of Buck(1948) and Bums(1972) and used exiting literatures as reference. The data were analyzed using means, standard deviations, t-test, one-way ANOVA, and Scheffe's test. The results obtained from the study are as follows: First, the mean level of college students' self-differentiation was 2.81, which is about average. Some significant gender differences were found in the areas of self-intergration, family projection, and emotional separation. Male students scored higher on self-intergration, whereas female students score higher on family projection and emotional separation. Second. self-differentiation was higher when the student drew a house with smoke coming out of the chimney, a single-story house with flat roof, or with detailed description of curtains, roof and roof tiles. Third, self-differentiation seemed to be higher when branches and fruits were included, when there was no expression of roots, when large crowns and branch openings were presented, and when no slant lines or base lines appeared. Forth, self-differentiation showed ㅁ higher level when the portrait shows eyes, mouth and neck without omission, when it included the whole body instead of face only, and when there was no person with just a profile, a back, or with a stiff posture, and when there was no weak and thin lines. Individuality also marked higher if a person was in motion and than one person was added. Finally, self-differentiation showed significant difference according to the overall harmony of the drawing, ordering of contents, hand pressure, the kind and shape of tree, and presence of other persons. The more harmonious the picture was, and the more family members are added, the higher the level of self-differentiation was.

This survey of 836 midlife women ($51.0{\pm}4.0$ yrs) was undertaken by exclusively a face to face interview by well-trained interviewers guarantying data collection of higher quality. This survey data was analyzed using the SPSS program. The main purpose of this study was to describe the factors affecting self-rated health status, including dietary habits and physical mental social factors. In the self-rated health status of a 'good' group, age was lower (p < 0.05), monthly income was higher (p < 0.01), dietary habits score (p < 0.001) and appetite (p < 0.001) and the degree of movement (p < 0.001) and life satisfaction (p < 0.001), marital intimacy (p < 0.001) and relationship satisfaction with their children (p < 0.001) were significantly higher than the 'bad' group. The level of depression (p < 0.001) and severe feeling of menopausal symptoms (p < 0.001) were significantly higher in the 'poor' group. The results of correlation analysis demonstrated that educational level (r = 0.069, p < 0.05), income (r = 0.157, p < 0.001), eating habits (r = 0.235, p < 0.001), appetite (r = 0.263, p < 0.001), life satisfaction (r = 0.197, p < 0.001), marital intimacy (r = 0.167, p < 0.001), child relationship satisfaction (r = 0.149, p < 0.001), positive attitude toward menopause (r = 0.070, p < 0.05) showed a positive correlation, but depression (r = -0.122, p < 0.001) and menopausal symptoms (r = -0.292, p < 0.001) showed a negative association with self-rated health status. The predictable factors affecting the self-rated health status of middle-aged women were examined by multiple regression analysis. The 'menopausal symptoms - physical discomfort' was the most important variables followed by the 'appetite', 'eating habits', 'menopause symptoms - sensory problems', 'BMI', 'positive attitude toward menopause' and 'high marital intimacy'. These results showed that the 'appetite' and 'eating habits' are important factors affecting the self-rated health status. Therefore, a program of dietary education must be considered for the effective health education and counseling of middle-aged women.

Although dental laboratory technicians are prone to be exposed to various work-related health hazardous materials such as dusts, chemicals, etc., the prevalence and nature of work-related health problems of them have not been a matter of great concern in the field of occupational health service in Korea. The purpose of the present investigation was to describe a collected profile of subjective health symptoms and their attributable factors in Korean dental laboratory technicians. A questionnaire listing five groups of health symptoms and five health symptom-related factors was mailed to randomly selected 1,900 dental laboratory technicians. Among them, 1,344 dental laboratory technicians filled out the questionnaires and returnde them. Five groups of health symptoms included musculoskeletal symptom, dermal symptoms, respiratory symptoms, eys symptoms, and ear symptoms. Five health symptom-related factors were occupational environment-related health risk factors, work history, health related habits and status, use of personal protective equipment and general characteristics. Detailed parameters of health risk factors were work posture, vibration, and chemical or physical hazards such as dust, fume, vapor, solvent, light, and noise for occupational environment-related factors; work place, area, number of employees, work hours, career, work part, and work load for work history; Broca's index, hours of sleep, eating, smoking, alcohol, exercise, health examination, and self assessed health status for health habits and status; face masks, goggles, and so on for use of personal protective equipment, and; age, sex, marital status, and education for general characteristics. Before the start of main survey, a pilot survey was carried out for validity and reliability tests of the questionnaire. All the data obtained were coded and analyzed with PC/SAS 6.12 program. The prevalence of health symptoms was the highest in musculoskelton (87.3%), and followde by eyes (78.9%), respiratory organs (64.3%), ears (57.8%), and skin (52.2%) in descending order. Statistically significant risk factors by multiple logistic regression analyses were sex, health examination, self assessed health status, and hand/finger posture in musculoskeletal symptoms; sex, self assessed health status, career, acid gas, and hand contact with resin mixture in deraml symptoms; Broka's smoking, exercise, self assessed health status, and face mask in respiratory symptoms; sex, hours of sleep, self assessed health status, work hours, work load, plaster dust, inadequate lighting, and goggle in eys symptoms, and eating, smoking, self assessed health status, and work load in ear symptoms. With the above considerations in mind, prevalence of subjective symptoms among Korean dental laboratory technicians was relatively high, and they were attributable to most of the occupational environment-related factors, work history, use of personal protective equipment, health habits and status, and general characteristics. Particularly, it is suggested that health promotion programs for promoting self- assessed health status and smoking cessation, preventive measures for protection of the female technicians’health, and reducing work load be necessary, since those factors were associated with more than one subjective symptom.
