It is a great role that the character of man or woman could be distinguished by hair on the aspect of ornament. Hair will be support of beautifulness of human being in various permanent wave by many kinds of its drugs. Hair is based upon the skin which enroll the body of high living animals and have multiple membrane structure. This study used rat and the effects of commercial permanent wave products to skin which are composed with thioglycolic acid and bases. Results are as follows. Permanent wave penetrated to 4 hours later with steady state in skins and was not significant changeable after 20hr later. In case of neutralizer with thioglycolic acid lag time and permeability coefficient in healthy skin is 3.38hr and $0.094^{\mu}g/cm^{2}$ ${\cdot}$ hr, it old skin is 3.48hr and 0.129$^{\mu}g/cm^{2}$ ${\cdot}$ hr, and it wounded skin is 4.72hr and $0.158^{\mu}g/cm^{2}$ ${\cdot}$ hr. In conclusion, lag time and permeability coefficient in old skin and wounded skin are faster than healthy skin. In vivo which was studied by general time and method of permanent wave. We notified that fine rinkle and rash of skin were changeable in the case of treating with permanent wave drugs than normal skin. We can see even rash and eruption by the naked eye.

In this paper, we propose a real-time face detection, tracking and tilted face image correction system using multi-color model and face feature information. In the proposed system, we detect face candidate using YCbCr and YIQ color model. And also, we detect face using vertical and horizontal projection method and track people's face using Hausdorff matching method. And also, we correct tilted face with the correction of tilted eye features. The experiments have been performed for 110 test images and shows good performance. Experimental results show that the proposed algorithm robust to detection and tracking of face at real-time with the change of exterior condition and recognition of tilted face. Accordingly face detection and tilted face correction rate displayed 92.27% and 92.70% respectively and proposed algorithm shows 90.0% successive recognition rate.

The general ground control system has control and information display functions for the operation of a single unmanned aerial vehicle. Recently, the function of the single ground control system extends to the operation of multiple UAVs. As a result, operators have been exposed to more diverse tasks and are subject to task overload due to various factors during their mission. This study proposes an adaptive ground control system that reflects the operator's condition through the task overload measurement of multiple UAV operators. For this, the ground control software is developed to control multiple UAVs at the same time, and the simulator with six degree-of-freedom aircraft dynamics is constructed for realistic human-machine-interface experiments by the operators.

Current binocular stereoscopic displays cause visual discomfort when objects with large disparities are present in the scene. One solution for improving visual comfort is synthetic depth-of-field processing, which simulates the characteristics of a human visual system. With this technique, visual comfort is improved by blurring portions of the background and/or foreground in the scene. However, this technique has the drawback of degrading overall image quality because the blurring is typically applied to both left and right images. To alleviate the visual discomfort, we propose a novel disparity-based asymmetrical filtering technique. Proposed technique applies the filtering to the image of one eye only, and controls the blur level according to the disparity information between stereoscopic images. We investigate the effects of this technique on stereoscopic video by measuring visual comfort and apparent sharpness. Our results indicate that disparity-based asymmetrical filtering can improve visual comfort of stereoscopic video while it maintains apparent sharpness if unfixated regions with large disparities are blurred under the appropriate filtering condition.

This study is designed to produce basic data on the nursing intervention between infants and mothers after discharge from hospitals. This research is carried by investigating the nursing intervention during their after-delivery staying in the hospitals located in Pusan. The object of this study includes the neonatal wards of 51 hospitals. Data collection was carried from the 3rd of September, 2001 to the 4th of October in the same year. Tools for measurement using in this research is the nursing checklist designed by these researchers. The data were analyzed by using SPSS and the output was produced in frequency and percentage considering general characteristics and nursing activities. On the course of investigation, it was revealed that the average number of items checked are as follows; total beds in one hospital came up to 360.1, the beds in each newborn infant ward came up to 36.1, in each ward the numbers of incubators came up to 9.2 and intensive care unit to 1.7. In each ward 8.4 nurses and 2.9 nurse aids were working at that time. In each hospital, secure of air way, physical examination, eye care, umbilical cord care, maintenance of body temperature, identification of infant, nutritive condition, safety and danger management, infection management, mother-infantile interaction, medical assistant to doctor, medication and discharge education were comparatively well done. But, in case of emotional, social and cognitive aspect of nursing activities through interactions between newborn infants and nurses as substitutes are not reached to the adequate level. In the end, this study hereby suggests that further investigation on the device to facilitate the interaction between newborn infant and nurse as a nursing intervention of high quality.

Purpose: We investigated the effects of emotional labor and workplace violence on various physical and mental health outcomes among female workers. Methods: We obtained data from 24,760 female workers who participated in the 4th Korean Working Conditions Survey (2014). Hierarchical logistic regression analysis was used to analyze the relationships. Results: Female emotional workers were more exposed to workplace violence than were female non-emotional workers. Verbal abuse was the most common type of workplace violence. Logistic regression analyses revealed that (1) emotional labor was significantly associated with higher odds of having musculoskeletal or abdominal pain (physical health outcomes), along with overall fatigue (a mental health outcome), and (2) workplace violence experiences were significantly associated with higher odds of musculoskeletal pain, headache/eye strain, abdominal pain, depression/anxiety disorder, overall fatigue, and insomnia/sleep disturbance, after controlling for covariates. Conclusion: This study demonstrated that both emotional labor and workplace violence have negative effects on physical and mental health. However, workplace violence experience has a stronger negative impact on health outcomes than does emotional labor alone. A management system to eradicate workplace violence and programs aimed at managing emotional labor are urgently needed at the organizational level.

Transient anisocoria is rare during blowout fracture reconstruction. We report a case of transient anisocoria occurring during medial blowout fracture reconstruction and review the relevant literature. A 54-year-old woman was struck in the face and was admitted for a medial blowout fracture of the left eye. During the operation, persistent bleeding occurred. To control this bleeding, a 1% lidocaine solution with 1:200,000 epinephrine was applied to the orbital wall with cotton pledgets. In total, 40 mL of local anesthetic was used for the duration of the operation. After approximately three hours of the surgery, the ipsilateral pupil was observed to be dilated, with sluggish response to light. By 3 hours after the operation, the mydriasis had resolved with normal light reflex. In conclusion, neurological and ophthalmologic evaluation must be performed prior to blowout fracture surgery. Preoperative ophthalmic evaluation is simple and essential in ruling out any preexisting neurologic condition. Moreover, surgeons must be aware of the fact that excessive injection of lidocaine with epinephrine for hemostasis during orbital wall surgery can result in intraoperative anisocoria. Anisocoria-related situations must be addressed in a proficient manner through sufficient understanding of the mechanism controlling the pupillary response to various stimuli.

Aldose reductase (AR), the principal enzyme of the polyol pathway, has been shown to play an important role in the diabetic complications, including diabetic cataract. The inhibitors of AR, therefore, would be potential agents for prevention of diabetic complications. As part of our ongoing project directed toward the discovery of preventive and/or treatment for diabetic complications, 48 Korean herbal medicines have been investigated with an in vitro evaluation system using aldose reductase inhibitory activities. Of these, 12 herbal medicines exhibited a significant inhibitory activity against aldose reductase. Particularly, seven herbal medicines, i.e., Eurya japonica, Chrysanthemum indicum, Akebia quinata, Saururus chinensis, Catalpa bignonioides, Lonicera japonica, Vitex rotundifolia showed two times more potent inhibitory activity than the positive control 3.3-tetramethyleneglutaric acid (TMG). In addition, Catalpa bignonioides showed the retardation of cataract-opacification of the lens of the eye under diabetic condition by xylose. Therefore, this result may provide a potential therapeutic approach for preventing and treating diabetic cataracts.

Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(${\beta}=-0.410$) had the influence on the oral health-related quality of life, nasal dryness(${\beta}=0.230$), age(${\beta}=0.189$), and halitosis (${\beta}=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.
