The assistive devices for disabled people are being highlighted even in industrial aspects through the policy and support for disabled people, enactment of regulation for the improvement of accessibility of disabled, technological innovation and product development. Recently, internet access with the sense of touch and hearing and utilizing electronic publishing contents and e-mailing are being convenient through the product of ICT development such as screen reader for visually impaired people, braille display, screen enlarger, text converter and others. Even so, in rapidly changing digital media smart era, the accessibility of visually impaired people is still poor and assistive devices and alternative formats are in need of improvement. Therefore, in aspect of the research and development innovation, this study proposes the implementation directions for improvement of accessibility by analyzing the current situation and structure of alternative formats and assistive devices for visually impaired people. As a result, in the future, various types of digital information are expected to be converted into a customized and realistic forms and distributed through a dedicated disability products or smart devices.

위에서 살펴본 바와 같이 나는 급성 턱관절장애의 경우, 첫번째 유형은 주로 턱관절 디스크공간의 문제와 하악의 위치를 바로잡아주는 근육의 문제가 주 원인일 것으로 추정하고 있다. 만약 턱관절 디스크공간이 정상공간이라면 턱의 지그재그 움직임이나 턱관절잡음, 턱통증, 턱탈구, 그리고 개구장애 등이 발생할 수 없기 때문이다. 그리고 근육의 문제 중에서는 턱관절 디스크원판을 양측에서 잡아주는 내외측 익돌근의 문제가 가장 많은 영향을 미치고 있다. 특히 내측 익돌근의 긴장 및 수축이 디스크 원판을 내측으로 빠져나가게 함으로써 하악의 좌우 지그재그 움직임을 야기시키고 턱관절잡음이나 턱통증 및 개구장애를 유발하기 때문이다. 나머지는 저작에 관여하는 근육들이 그 다음으로 영향을 미치는 것으로 예측하고 있다. 그러나 제2형 급성 턱관절장애의 경우는 제1형 급성 턱관절장애가 한단계 더 발전하여 이와 연관된 근육이나 인대의 긴장수축이 오랜 시간 진행되어, 이들이 다시 상부 경추의 아탈구와 두개골의 비정상적 움직임에까지 영향을 미쳐 나타나는 것으로 생각된다. 그렇게 되면 뇌에서 필요 충분한 뇌혈액공급이나 뇌척수액순환의 문제를 일으킬 수 있기 때문이다. 그리고 제1형 만성 턱관절장애의 경우는 제2형 급성 턱관절장애가 좀 더 진행되면서 척추 및 근골격계의 구조변화, 교합 및 턱의 구조변화 그리고 안면구조의 변화에 이르기까지 점점 진행되어 나타나는 것으로 보인다. 따라서 각종 척추 디스크질환, 관절질환을 비롯해서 두개천골계의 순환문제, 부정교합 및 턱 비대칭, 안면 비대칭의 문제를 유발하게 된다고 추정된다. 그러나 두번째 유형의 만성 턱관절장애는, 턱에서 지속적이고 반복적인 그리고 과다한 부정적 자극들이 오랜 기간 누적되면서 턱에 분포된 C 섬유를 비롯한 3차신경의 가소성변화를 유발하면서 결국 중추신경계를 포함하여 전체신경계의 회로망에까지 파급되어 다양한 만성질환 또는 난치성 질환들이 양산되는 것으로 추정하고 있다. 아마도 지금까지 서양의학에서 아직 밝혀내지 못한 대부분의 질병들이 여기에 포함되지 않을까 하는 것이 나의 생각이다.

Purpose : As a result of advances in neonatal intensive care and perinatal care, neurodevelopmental outcomes of very low birth weight infant(VLBWIS) is expected to lead to improvement. The aim of this study was to report neurodevelopmental outcomes and risk factors of neurologic impairment of very low birth weight infants during the past 10 years. Method : We performed a retrospective study of 447 newborn infants below 1,500 gm admitted to neonatal intensive care unit of Taegu Fatima Hospital between Janury 1996 and December 2004. Infants were subdivided into group 1(Jan. 1996 to Dec. 1998), group 2(Jan. 1999 to Dec. 2001), and group3(Jan. 2002 to Dec. 2004). We analyzed epidemiologic data to study changes of neurodevelopmental outcomes and risk factors of neurologic impairment. Result : The incidence of cerebral palsy and developmental delay decreased significantly in periods 2 and 3(vs period 1; cerebral palsy 10 percent, developmental delay; 18 percent, P<0.05). Periventricular leukomalacia incidence decreased in period 3(vs period 1; 14.5 percent, P<0.05). The overall survival rate of VLBWIS increased significantly in period 2 and 3(vs period 1; 90.0 percent, P<0.05). The risk factors of neurologic impairment are long-term ventilator care(above 1 wk), low Apgar score, low gestational age and low birth weight. Conclusion : In the most recent 10 years, neurologic impairments of VLBWIS significantly decreased, as a result of advances in neonatal intensive care and perinatal care.

Background: Recently, many cardiac centers have been using aprotinin to reduce operative bleeding in cardiac operations using cardiopulmonary bypass. A variety of reports have confirmed the effectiveness of the drug in cardiac operations. In addition to the operations which could be considered to cause severe operative bleeding such as redo operation, long cardiopulmonary bypass operation and etc, the use of aprotinin is increasing in the field of primary cardiac operations. Varying doses of regimen have been introduced since the first report by Royston et al, and also various opinions on the effectiveness and safeness of the each regimen have been reported. We reviewed our own experience of the full dose aprotinin regimen(Hammersmith regimen) retrospectively. Material and Method: From October 1994 to February 1998, 40 cases of cardiac operative patients were randomized into two groups: aprotinin group(20 patients) which received a full dose aprotinin regimen and control group(20 patients) which did not receive aprotinin. To evaluate the degree of bleeding decrease, we analysed and compared the amount of postoperative 6 hours and 24 hours bleeding in the each group. To confirm the renal dysfunction, we measured the postoperative creatinine level. Result: In the amount of postoperative 6 hours bleeding, a statistically significant bleeding decrease was demonstrated in the aprotinin group compared to the control group(aprotinin group: 186${\pm}$40cc, control group:409${\pm}$69cc, P=0.010). Similar result was observed in the postoperative 24 hours(aprotinin group:317${\pm}$53cc, control group: 671${\pm}$133cc, P=0.024). Conclusion: We concluded that full dose regimen of aprotinin can remarkably reduce postoperative bleeding in cardiac operations without significant renal dysfunctions.

If the software is developed to analyze the speech disorder, the application of various converged areas will be very high. This paper implements the user-friendly program based on CART(Classification and regression trees) analysis to distinguish between normal and pathological voices utilizing combination of the acoustical and HOS(Higher-order statistics) parameters. It means convergence between medical information and signal processing. Then the acoustical parameters are Jitter(%) and Shimmer(%). The proposed HOS parameters are means and variances of skewness(MOS and VOS) and kurtosis(MOK and VOK). Database consist of 53 normal and 173 pathological voices distributed by Kay Elemetrics. When the acoustical and proposed parameters together are used to generate the decision tree, the average accuracy is 83.11%. Finally, we developed a program with more user-friendly interface and frameworks.

This study looked into the inner experience of foster mothers who adopted children under 3 months old and found out they were disabled while they were rearing with Van Manen's hermeneutic phenomenological approach. In-depth interviews were used with six foster mothers who live in Seoul, Gwangju, Gyeongsangnam-do, and Jeollabuk-do. The study resulted in a hermeneutic writing with titled "Love of Mothers Who Want to Make Their Children's Dreams Come True" with six essential themes as follows: 'being at a loss wrapped in a dense fog,' 'venting off the frustration,' 'gratitude amid painfulness,' 'bold confrontation with prejudices,' 'disabled children's return to the center of their moms' life,' and 'expectation for their future life.' As they are disabled, foster mothers want to rear their children with more care and attention to make their children's dreams come true. Seen above, this could be interpreted as mothers' love to a life. For foster mothers, the disability of their adopted children is not a burden but an expectation for a new world. They help the children live by themselves. It shows that every child can have his own home.

Trauma to the primary teeth may have an effect on the successive permanent teeth. Thus, the treatment plans should be focused on safety of their permanent teeth. The degree of developmental disturbances in those permanent teeth depends upon many factors including the age of the children, developmental conditions of the affected teeth, types and severities of trauma and time interval from the moment of trauma to the initial treatment the patients received. The complications of the effected permanent teeth vary from the mild enamel hypoplasia to the premature finishing of teeth development. In this study, children whose ages were 33 months, 5 years, and 26 months presented the developmental disturbances to their permanent teeth, which resulted from the trauma to the primary teeth: the intrusion, the avulsion, and the subluxation. There showed a mild complication in the case of subluxation resulting in enamel hypoplasia, but, the more severe complication of the root dilacerations occurred in the case of intrusion. Furthermore, the 5-year-old patient whose primary dentition was near in transition period to the permanent one, the more complicated problem such as stop of root development of the permanent teeth was resulted from the avulsion. Thus, one should assume that the types of trauma and the age of the children at the moment of trauma have different effects on those successive permanent teeth. In conclusion, when the trauma that causes changes in the position of primary teeth happened, it is important to arrange an appropriate treatment procedure considering the types of trauma and the developmental conditions of the permanent teeth.

The aim of this study is to investigate the coping behavior according to the personality type of mothers of children with disabilities. The study included 102 mothers of children with disabilities and the study was conducted from june to september in 2020 based on the questionnaire about the personality type and coping behavior. Personality types were evaluated using Enneagram, and coping behavior was evaluated using the Korean Coping Behavior Scale for Parents of Children and Adolescents with Disabilities As a result of the study, the belly type was the most common personality type of mothers with disabilities. As for coping behavior, active problem-solving for children with disabilities showed the highest score. As a result of analyzing the coping behavior according to the personality type of mothers of children with disabilities, there were significant differences in the coping behavior, strengthening marital cooperation, and pursuing social-emotional support. As a result of post-verification, there were significant differences between heart type and belly type in coping behavior, strengthening marital cooperation, and pursuing social-emotional support, and heart type scored higher than belly type. When conducting interventions for families of disabled children, it will be possible to provide more effective services by predicting coping behaviors according to the personality type of mothers of disabled children and presenting individualized programs.

Neonatal bleeding is a common problem encountered in nursery rooms or neonatal intensive care units, especially among premature infants. Furthermore, owing to recent remarkable improvement of neonatology, survival rates of preterm neonates have increased; hence, neonatal bleeding cannot be emphasized enough. Since the total blood volume of neonates is small, bleeding can be one of the causes of morbidities and mortalities. Therefore, rapid diagnosis and immediate therapy is urgently needed. The patient's medical history including a familial history of a bleeding disorder or of a previously affected infant who suffered from bleeding along with maternal and neonatal drugs can provide important diagnostic clues. Presence of bleeding with or without petechiae and ecchymoses in a healthy term or late preterm infant with thrombocytopenia but normal prothrombin time and activated partial thromboplastin time strongly suggests a congenital bleeding disorder. For a sick infant who is bleeding from multiple sites, an acquired disorder such as disseminated intravascular coagulation is suspected. Intracranial hemorrhage in term or late preterm infants without a history of birth trauma is highly suggestive of coagulation disorders. The purpose of this review is to summarize recent advances in diagnostic methods is as well as basic concepts of neonatal hemostatic disorders. First, an outline of background information will be presented followed by a discussion of primary and secondary hemostatic disorders as well as inherited and acquired disorders.
