The brain is the body's most organized and controlled organ, and it governs various psychological and mental functions. A brain abnormality could greatly affect one's physical and mental abilities, and consequently one's social life. Brain disorders can be broadly categorized into three main afflictions: stroke, brain tumor, and dementia. Among these, stroke is a common disease that occurs owing to a disorder in blood flow, and it is accompanied by a sudden loss of consciousness and motor paralysis. The main types of strokes are infarction and hemorrhage. The exact diagnosis and early treatment of an infarction are very important for the patient's prognosis and for the determination of the treatment direction. In this study, texture features were analyzed in order to develop a prototype auto-diagnostic system for infarction using computer auto-diagnostic software. The analysis results indicate that of the six parameters measured, the average brightness, average contrast, flatness, and uniformity show a high cognition rate whereas the degree of skewness and entropy show a low cognition rate. On the basis of these results, it was suggested that a digital CT image obtained using the computer auto-diagnostic software can be used to provide valuable information for general CT image auto-detection and diagnosis for pre-reading. This system is highly advantageous because it can achieve early diagnosis of the disease and it can be used as supplementary data in image reading. Further, it is expected to enable accurate medical image detection and reduced diagnostic time in final-reading.

This study aims at investigating the relationship between voice and the image information carried within the voice. Whenever we hear somebody talking, we form a mental image of the speaker. Is it accurate? Is there a relationship between the voice and the image triggered by the voice? To answer these questions, speech samples form 8 males and 8 females were recorded. Two photos were taken for each speaker: the whole body photo (W) with physical characteristics present, and the face close-ups (F) without much physical details revealed. 361 subjects were asked to match the voices with the corresponding photos. The results showed that 5 males and 5 f3males (with W) and 2 males and 4 females (with F) were correctly identified. More interestingly, however, even in the mismatches, there was a strong tendency for participants to agree on which voice should correspond to which photo. The participants also agreed much more readily on their favorite voice than on their favorite photo. It seems voice does carry certain information about the physical characteristics of the speaker in a consistent manner. These findings have some bearings on understanding the mechanism of speech production and perception as well as on improving speech technology.

The human face can provide a great deal of information in regard to his/her race, age, sex, personality, feeling, psychology, mental state, health condition and ect. If we pay a close attention to the aging process, we are able to find out that there are recognizable phenomena such as eyelid drooping, cheek drooping, forehead furrowing, hair falling-out, the hair becomes gray and etc. This paper proposes that the method to estimate the age by analyzing these feature components for the facial image. Ang we also introduce the method of facial image synthesis in accordance with the cange of age. The feature components according to the change of age can be obtainec by dividing the facial image into the 3-dimensional shape of a face and the texture of a face and then analyzing the principle component respectively using 3-dimensional model. We assume the age of the facial image by comparing the extracted feature component to the facial image and synthesize the resulted image by adding or subtracting the feature component to/from the facial image. As a resurt of this simulation, we have obtained the age changed ficial image of high quality.

Background: This study aimed to demonstrate the importance to recognize subjective body image on their mental health on adolescents. Methods: We used the chi-square test and the multiple logistic regression model to analyze the data of the "Korean Youth Health Behavior Survey in 2018" (n=42,259) conducted by the Korea Centers for Disease Control and Prevention. Results: As a result of the analysis, suicide ideation increased when the subject body image is thin and fat. Especially, the suicide ideation who recognized the subjective body image as thin is higher (odds ratio [OR], 1.666; 95% confidence interval [CI], 1.050-1.295), and who recognized the subjective body image as fat is higher (OR, 1.134; 95% CI, 1.032-1.245) than the group who recognized the subjective body image as normal. Conclusion: When preparing a health policy on adolescent suicide issues, we need to consider the association between subjective body image and suicide ideation.

공간, 시간적 환경정보를 함께 저장하는 일화기억(episodic memory)은 알츠하이머병에 의해 손상될 뿐만 아니라 일반 노화과정에서도 손상될 수 있다. 본 연구의 목적은 인지기능인 일화기억을 내적회상 기법을 사용하여 평가함으로써 초기 알츠하이머성 치매 환자의 일화기억을 분석하고 평가하는 것이다. 따라서 본 연구에서는 사진이나 동영상처럼 뇌에 투사되는 피시험자 자신의 과거를 직접 회상한 이미지(the mental image)를 분석하는 새로운 방법을 사용하였다. 초기 알츠하이머성 치매환자3명, 경도 우울증 환자 1명, 대조를 위한 건강한 노인 2명에게 검사 당일로부터 하루, 일주일, 한달 전 그리고 원과거(remote)에 있었던 일을 회상하게 하였다. 회상된 이미지 안에서의 감정상태, 이미지의 색, 사건 발생 순서 등의 중점을 두고 피시험자의 응답을 분석하였다. 순행성기억(anterograde memory) 손상을 관찰하고자 피시험자에 그들이 검사 당시 재현한 모든 이미지를 검사 다음날 다시 상기하도록 요구하였다. 3명의 환자군 모두 회상한 이미지들 사건 발생순서에 맞게 정리하는데 실패하였다. 이들은 대조군과 같은 수의 이미지를 회상해 내었지만, 색이 선명하지 않고 사진과 같은 정적인 이미지를 회상하였다. 이러한 결과는 초기 치매환자가 최근기억(recent memory)을 화상 하는데 일차적으로 손상이 있을 시사하며, 또한 의미기억의 양적인 손상보다 질적 손상이 먼저 발생함을 보여주었다.

Purpose: The purpose of this study was to examine the sexual maturation, body image, and self-esteem of Korean elementary school girls with symptoms of precocious puberty compared to those with no symptoms of precocious puberty. Methods: The subjects were 309 girls of lower grades in elementary school. Tanner's Sexual Maturation Rating (SMR), Self Image Scale, and Self-esteem Scale were utilized to determine the presence of symptoms of precocious puberty, body image, and self esteem. Collected data were analyzed by Chi-square test, independent t-test, and one-way ANOVA using the SPSS/WIN 17.0 program. Results: The percentage of the girls with breast development was 14.9%. Breast development usually began in the third grade (56.5%). Of the subjects, 0.3% were experiencing menstruation. Breast development was related to grade, age, height, weight, and a cause of worry. There was a significant difference of body image between girls with breast development in the first grade and in the second grade. Conclusion: An effective intervention that can improve the self-image of children with symptoms of precocious puberty should be developed to prevent and treat physical and mental problems related to sexual maturation.

Purpose: To compare the visibility of the mandibular canal at the different radiographic methods such as conventional panoramic radiographs, Vimplant multi planar reformatting (MPR)-CT panoramic images, Vimplant MPR-CT paraxial images and film-based DentaScan MPR-CT images. Materials and Methods: Data of 11 mandibular dental implant patients, who had been planned treatment utilizing both panoramic and MPR-CT examination with DentaScan software (GE Medical systems, Milwaukee, USA), were used in this study. The archived axial CT data stored on CD-R discs were transferred to a personal computer with 17' LCD monitor. Paraxial and panoramic images were reconstructed using Vimplant software (CyberMed Inc., Seoul, Korea). Conventional panoramic radiographs, monitor-based Vimplant MPR-CT panoramic images, monitor-based Vimplant MPR-CT paraxial images, and film-based DentaScan MPR-CT images were evaluated for visibility of the mandibular canal at the mental foramen, 1 cm, 2 cm, and 3 cm posterior to mental foramen using the 4-point grading score. Results: Vimplant MPR-CT panoramic, paraxial, and DentaScan MPR-CT images revealed significantly clearer images than conventional panoramic radiographs. Particularly at the region 1 em posterior to mental foramen, conventional panoramic radiographs showed a markedly lower percentage of 'excellent' mandibular canal images than images produced by other modalites. Vimplant MPR-CT and DentaScan MPR-CT images did not show significant difference in visibility of the mandibular canal. Conclusion: The study results show that Vimplant and DentaScan MPR-CT imaging systems offer significantly better images of the mandibular canal than conventional panoramic radiograph.

In order to investigate female workers' recognition of image making, this study conducted a survey of female workers in Daegu and obtained results as follows. First, according to the result of analyzing recognition of image making, many of female workers, 82.3% of whom were between 20s and 40s, replied that they were 'pure and lively'(41.8%) or 'elegant and womanly'(32.3%) but what they sought for in their mind was an elegant and womanly image. However, the image that a majority of female workers wanted to have in the future was 'elegant and womanly' (53.3%) and 'sexy and attractive'(27.4%). This suggests that our society still demand women to be womanly as well as sexy and attractive. Second, with regard to outward image by age, most female workers regardless of age thought that outward image is important for social life. This suggests that younger women recognize more the influence of image and, consequently, the necessity of image making. Thus, the recognition of the importance of outward image appears to result in the proportional enhancement of the consciousness of image management. Third, younger women have a great difference between their current image and the image they seek for and such a difference may be related to mental immaturity between ideal and reality. Fourth, as for the relationship between image making and occupation, those who engaged in service and beauty art highly recognized the importance of image making as they were greatly influenced by their outward image in their social life.
