용언은 그 어간이 여러 문법소와 결합하면서 자동적 음운 변동을 제외한 형태 변동이 있는가, 없는가에 의해 규칙 용언/불규칙 용언으로 구분할 수 있다. 이러한 불규칙 용언은 심성 어휘집에 어떤 형태로 저장되어 있으며, 규칙 용언과는 어떠한 관계가 있는지, 나아가 실어증 환자의 경우에는 정상인에 비해 어떤 행동장애를 보이며, 장애가 있다면 어느 경로의 손상으로 인한 장애인지를 알아보는 것이 본 연구의 목적이다. 이를 위해 이해성 실어증 환자 한 명과 음어적 실행증 현상을 동반한 경미한 정도의 실어증 환자를 피험자로 하였다. 실험 과제는 단어 채워 넣기 과제(word completion task)를 사용하였다. 즉 주어진 기본형 용언을 검사 문장의 문맥에 맞게 활용하여 채워 넣는 것이다. 실험 결과에 의하면 환자들은 규칙용언의 활용(예. 먹다/먹는)과 불규칙 용언 중 형태를 유지한 채로 활용하는 경우(예. 줍다/줍고)에는 거의 오류가 없었으나, 불규칙 용언이 형태 변화를 겪어야 할 경우(예. 줍다/주워)에는 대부분 오류를 보였다. 또 이때는 기본형(basic form)을 그대로 유지하는 오류 방향성을 관찰할 수 있었다. 이는 그간 문법으로 구분되어 오던 규칙 용언/불규칙 용언의 정보 처리보다는 형태 유지/형태 변화 정보 처리의 영향이 크다는 것을 알 수 있다. 특히 이해성 실어증 환자는 전체적인 오류율이 매우 높았는데, 규칙 용언의 경우에도 오류를 보였다. 이때, 용언의 어간에 해당하는 부분에는 오류가 없고, 뒤에 따르는 내용과의 관계를 파악해야 하는 문법 기능소, 즉 연결 어미에서 오류를 보여 정보의 유지, 통합에 문제가 있다는 기존의 연구와도 일치하는 결과를 나타냈다.환자는 시제 선어말 어미를 선택하는데도 어려움을 보임이 확인되었다. 실험 3 역시 실험 1과 실험2에서와 동일하게 처리의 어려움을 보였다. 이러한 실험 결과들은 국어의 존칭과 시제 선어말 어미가 통사부에서 구(XP)와 결합하여 새로운 구를 형성하는 통사적 접사로 해석할 수 있으며 Grodzinsky의 가설을 지지하는 결과를 보여 줌으로서 국어에서도 AgrP, TP, CP 사이의 통사적 위계가 있음을 뒷받침하는 증거가 된다.전처리한 Group 3에서는 IL-2와 IL-4의 수준이 유의성있게 억제되어 발현되었다 (p < 0.05). 이러한 결과를 통하여 T. denticola에서 추출된 면역억제 단백질이 Th1과 Th2의 cytokine 분비 기능을 억제하는 것으로 확인 되었으며 이 기전이 감염 근관에서 발견되는 T. denticola의 치수 및 치근단 질환에 대한 병인기전과 관련이 있는 것으로 사료된다.을 보였다. 본 실험 결과, $Depulpin^{\circledR}은{\;}Tempcanal^{\circledR}와{\;}Vitapex^{\circledR}$에 비해 높은 세포 독성을 보여주공 있으나, 좀 더 많은 임상적 검증이 필요할 것으로 사료된다.중요한 역할을 하는 것으로 추론할 수 있다.근관벽을 처리하는 것이 필요하다고 사료된다.크기에 의존하며, 또한 이러한 영향은 $(Ti_{1-x}AI_{x})N$ 피막에 존재하는 AI의 함량이 높고, 초기에 증착된 막의 업자 크기가 작을 수록 클 것으로 여겨진다. 그리고 환경의 의미의 차이에 따라 경관의 미학적 평가가 달라진 것으로 나타났다.corner$적 의도에 의한 경관구성의 일면을 확인

The social welfare law concerning the children, the elderly and the disabled has been sufficiently in the center of the discussion in the academic as well as practical arena. One can find however rarely academic proposals about the way of understanding, spheres affiliated with this legal system, and systematic characteristics. So these problems stay now vague. This article aims to approach to these points of issue. First, it tries to reveal the physical, psychological and psychic characteristics of these group of people. These situation are not to be effectively protected by norms and measures provided by other instruments of social security, i.e. social insurances and social assistances. Second, based upon these functional limits inherent to these instruments of social security the own system of the social welfare law is explored in this article. The discussing points are as follows; 1. the concept of social welfare law, 2. as core principles; realization of the personality and freedom based upon self-determination right, universalism and equality. 3. rearrangements of the legal provisions to bring harmony with the legal purpose and function of social welfare law. Finally, it is pointed that the evaluation of the relevant legislation is essential, since in this area the difference between the norm purpose and the reality could be immense.

The purpose of this study was to examine the relationship of dietary self-efficacy and illness beliefs, perceived benefits, and perceived barriers for the reduction of sodium intake in the elderly. A cross-sectional study was performed on 252 elderly people, aged 65 yrs and above, living in Daejeon Metropolitan city and Jecheon city, Chungbuk from March 21 to March 30, 2011. Dietary self-efficacy of three factors (resisting relapse, reducing salt and behavioral skills), perceived benefits and barriers, accurate and inaccurate illness beliefs were measured by 5 or 4 point Likert scale. With the increasing education level of the elderly, dietary self-efficacy, and accurate illness belief score increased and perceived barrier score decreased. Perceived benefits score was higher in the subject living alone compared to those living with siblings or spouses. Among three factors of dietary self-efficacy, reducing salt was scored highest and behavioral skills scored lowest in the elderly. Recording meal diary and reading labels for salt content in the items of behavioral skills showed lower score than other items. Accurate illness beliefs and perceived benefits were more scored than inaccurate illness beliefs and perceived barriers respectively in the subjects. The subjects with higher accurate illness beliefs, lower inaccurate illness beliefs, higher perceived benefits, and lower perceived barriers for the reduction of sodium intake showed higher dietary self-efficacy. In summary, accurate illness beliefs and perceived benefits positively correlated with dietary self-efficacy for the reduction of sodium intake in the elderly, whereas inaccurate illness beliefs and perceived barriers are negatively correlated.

Introduction：Research on attachment in view point of the developmental perspective which began in the 1940s progressed during several decades. Many investigators focused mother-child separation in early attachment studies, and moved to the relationship with childhood psychopathology. Recently attachment theory and research are moving forward along the intergenerational transmission of attachment patterns, and adolescents and adult mental disorders in the developmental perspectives. Methods：We surveyed the research papers through Medline search, attachment-related monographs, and review or original papers published in Korean journal. Results：Developmental attachment researches have demonstrated convincingly that insecure attachment in infancy is associated with attachment disorder; several childhood psychopatholgy, such as institutional care and adoption, aggression and behavioral problems, childhood anxiety disorders and depressive disorders, gender identity disorder and feeding disorder, and child abuse and maltreatment; peer relationship and social competency, and parental behaviors. Recently the methodological advances including the Adult Attachment Interview that systematically assesses the adults' recollections of the earlier parent-child relationship they experienced could move beyond attachment researcher's initial concern with infancy to consider attachment processes throughout the life span. We could find that the quality of attachment was associated with several mental disorders in adolescents and adults significantly. Conclusion：Attachment theory would have focused on more specific parent-child relationship than general parental behavior. Recent attachment theory underscores its evolutionary origins to promote development of infant and contribute to human survival in psychobiological bases. Advances in attachment research could unite interests in evolutional biology and developmental psychology in understanding early parent-child relationship, and apply to clinical issues concerning mental health throughout the life span.

Background: This study purposed to examine the difference in the prevalence of obesity at each stage among people with and without disabilities considering the severity and type of disability. Methods: The study targeted a total of 1,315,967 people, including 68,418 disabled and 1,247,549 non-disabled, who completed the national health screenings. Logistic analysis and average marginal effect analysis were conducted in three stages (pre-obesity, obesity, severe obesity). Those analyses were conducted considering the severity and type of disabilities. Results: People with disabilities were more likely to be at all stages of obesity than non-disabled people. In severely disabled people, the probability of obesity was higher than non-disabled people at all stages of obesity, but mildly disabled people had a higher only in the severe obesity stage, no difference in obesity stage, and a low in the pre-obesity stage. In physical and mental disabilities, the probability of obesity was higher than non-disabled people at all stages of obesity, but external physical function and internal organs disabled had a lower in the obesity and pre-obesity stage, and no difference in severe obesity stage. Conclusion: This study found that people with disabilities had a higher relationship with obesity than people without disabilities. In addition, severity and types of disabilities have different effects on the stage of obesity. Therefore, it is necessary to care about the health inequality and health of disabled people considering their severity and types of disabilities.

E-learning in Korea supports different educational needs of diverse learners. E-learning became one of the major source of educational services for schools, higher education, lifelong learning, and for special education. Many e-learning contents offered by cyber universities use HTML, CSS, and Flash, and these are known to have limitations on accessibilities. People with disabilities or aged have problems accessing such contents. The purpose of this study is to evaluate accessibility of Flash e-learning contents offered by 9 cyber universities. AccChecker is used to assess accessibility of the contents. The result shows many errors and warning with Text Equivalents, Keyboard Navigation, Properties, Depth of Tree, and Structures that restrict access. In order to improve the quality and expansion of quality e-learning contents, we need aggressive measures to obtain accessibility of contents, and these should be designed at the planning phase rather than adjusted during the development stage. Furthermore, it is vital to train instructional designers, developers and the CEOs to realize the importance of accessibility and learn appropriate skills to increase accessibilities of e-learning contents.

This paper describes characteristics of a bone conduction telephone which was developed for conductive hearing impaired persons to call without additional devices and results of its performance test. Not only the hearing impaired but also normal hearing persons can use this telephone because we developed a bone conduction vibrator with which they can perceive speech signal using functions of air conductive hearing as well as bone conductive hearing. It also has tone control function compensating hearing losses for the hearing impaired originating from their hearing characteristics, and using this function together with received volume control it has received volume range of 20dB in loudness rating, which is similar effect as what a telephone set with built-in received amplifier has. From results of articulation and intelligibility tests for 19 hearing impaired persons, we can see that if their bone-conduction hearing loss is 61dB or less, they can understand words or sentences and response well with this telephone.

Objectives : The aim of this study was to examine the relationship between internet game addiction and psychiatric symptoms. Methods : A total of 447 adolescents who were recruited from a child and adolescent psychiatric clinic of university hospital completed a self-report questionnaire consisting of Korean Internet Addiction Self-scale (K-scale), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Korean-Attention-Deficit Hyperactivity Disorder Rating Scale (K-ARS), and Adolescent Happiness Index (AHI). They were classified into three internet user groups, non-addicted group (below or equal to 94), potential risk group (95 to 107) and high risk group (above or equal to 108) according to K-scale total score. Results : Significant mean differences in BDI, BAI, K-ARS, and AHI scores were observed among the three groups. The BDI, BAI and K-ARS scores showed positive correlation with K-score. The AHI score showed negative correlation with K-score. Conclusion : Findings of this study suggest that depression, anxiety, inattention, hyperactivity/impulsivity, and happiness are associated with internet game addiction.
