질화물 기반 물질은 발광다이오드의 효율 향상과 함께 널리 연구되는 물질의 하나이다. 그러나, 고유의 물성적 특성으로 인한 압전전기장 효과는 넓은 가시광영역에서 궁극적 효율 달성을 위한 장애가 되고 있다. 이를 극복하기 위한 방법 중 하나는 나노 구조이며, 특히 비극성면을 통한 나노구조의 구현은 압전전기장 효과를 제거할 수 있는 장점이 있다. 그러나, 현재까지 이를 위한 질화물 나노로드의 구현은 보통의 경우 발생하는 반극성면의 발현으로 인해 기술적 어려움이 많았다. 이를 위해 제시되는 방법 중 하나인 반복적 성장 기법을 통한 본 그룹의 성공적 나노로드의 구현과 함께, nucleation 조건의 변화에 따른 성장 과정을 분석하여 미래의 고효율 3차원 나노구조 발광 소자를 위한 단서를 제공하고자 한다. Fig. 1은 수소(a)와 질소(b)를 850도부터 1,050도까지 성장 온도를 달리하여 성장했을 때의 모양 변화를 나타내며 이를 통한 GaN nanorod 성장 영향에 대하여 논하고자 한다.

The most common cause of mouth breathing is obstacles caused by mechanical factors in upper airway. Mouth breathing could be consequently pathological cause of sleep-disordered breathing. Sleep-disordered breathing in children can cause growth disorders and behavioral disorders. The purpose of this study was to investigate relationship between upper airway and sleep-disordered breathing in children with mouth breathing. Twenty boys between 7 - 9 years old who reported to have mouth breathing in questionnaire were evaluated with clinical examination, questionnaires, lateral cephalometric radiographs, and portable sleep testing. This study assessed apnea-hypopnea index (AHI) and oxygen desaturation index (ODI) for the evaluation of sleep-disordered breathing and was done to investigate the correlation between these values and the upper airway width measured by lateral cephalometric radiographs. There was no significant correlation with the size of the tonsils (p = 0.921), but the adenoid hypertrophy was higher in the abnormal group than in the normal group (p = 0.008). In the classification according to AHI and ODI, retropalatal and retroglossal distance showed a statistically significant decrease in the abnormal group compared to the normal group (p = 0.002, p = 0.001). As AHI and ODI increased, upper airway width tended to be narrower. This indicates that mouth breathing could affect the upper airway, which is related to sleep quality.

Among growth disorders, 'Short Stature' can be improved through rapid diagnosis and treatment, and for that, it is important to detect early'Short Stature'. It is recommended to measure the height steadily for early detection of 'Short Stature' and checking the kid's growth process, but existing height measurement methods have problems such as time and space limitations, cost occurrence, and difficulty in keeping records. So in this paper, we proposed an 'Development of Kid Height Measurement Application based on Image using computer vision' method using smart phones, a medium that is highly accessible to people. In images taken through a smartphone camera, the kid's height is measured using algorithms from OpenCV, a computer vision library, and the measured heights were printed on the screen through 'a comparison graph with the standard height by gender and age' and 'list by date', made possible to check the kid's growth process. It is expected to measure height anytime, anywhere without time and space limitations and costs through this proposed method, and it is expected to help early detection of 'Short Stature' and other disorder through steady height measurement and confirmation of growth process.

Nursing problems of 48 hospitalized patients with Conduct Disorder at a Child-Adolescent psychiatry inpatient were analyzed by reviewing nursing records. The results showed that the problems such as ineffective individual coping, impaired social interaction, disturbance in self-concept, potential for violence, alteration in parenting, altered growth and development were continued from early to later phase of the hospitalization and the other problems such as self-care deficit, anxiety, sleep disturbance, altered nutrition, hyperthermia were temporary. The etiologic factors related to these problems were underdeveloped ego, low self-esteem, dysfunctional parent-child relationship, some situational crises in family and handicap like mental retardation or epilepsy. Therefore nursing approach for the patients with Conduct Disorder should focus on ego growth and improvement of interpersonal relationship through systematic and long-term nursing plans and interventions for these patients and their family.

This study analyzes the process of overcoming prejudice and discrimination experiences of mothers with disabilities and looks for improvement points. It is interviewed 9 mothers of children with disabilities who were experiencing prejudice and discrimination while raising children with disabilities. The data collection was conducted from October to November, 2018 and one by on one in depth interview by using semi - structured questionnaires. Data analysis was done through consensual qualitative research (CQR). The result of CQR while it is a experiencing the process of prejudice and discrimination as well as coping the raising disabled children. 'Prejudice and discrimination experience of mothers with disabilities' and 'overcoming of discrimination experiences of mothers with disabilities' were derived. And the seven sub-regions, 28 categories, were finally constructed. The results of the study are as follows. Firstly, Prejudice and discrimination experiences of mothers with disabilities in raising children with disabilities are view of looking at children with disabilities comparing to those of normal children and children with disabilities. It seems that they want to treat the disabled child as the general child with an attitude of understanding and accepting the disabled child rather than looking at the disabled child with wrong perception, prejudice, stereotypes and rejection. Secondly, The process of overcoming the discrimination experiences of the mother of the disabled child is strengthening the cohesion and cohesion within the family in the process of accepting and coping with the disability family of the child with disabilities even if they raise the child with disability and have difficulties such as recognition bias and discrimination of the general public. Based on the results of this study, we suggested practical and policy implications for the mother's psychological stability of the child with disability and the disabled child's healthy life.

The aim of this study is to reveal development processes of mothers with disabled children as active human agents utilizing social welfare institutions. Many social welfare studies have generally described welfare service users as passive subjects alienated from welfare information and subordinate to dominant welfare system. However, this investigation indicates that they do not merely remain as passive policy targets. They also perform as active actors who seek for useful information, strategically acquire profits in the given system despite institutional constraints, and create new welfare institutions. Through in-depth interviews with 11 mothers of disabled children with brain lesions, this study has derived a grounded theory on the mothers' maturation processes in interaction with social welfare institutions, which consist 6 stages(entering, awakening, exploring, struggling, resigning and utilizing period). This substantive analysis on the survival processes of mothers with disabled children in the social welfare system provides empirical knowledge and evidence about relationship between the structure and agents. It also suggests a practical policy proposal for disabled people and their families based on these stages.

The purpose of this study was to present the causes and their mechanisms of eruption failure of teeth and to investigate the treatment modalities. There are so many reports about eruption failure, but most of them are dealing with local mechanical interferences. But, we have patients suffered from eruption failure of another causes. Many developmental failures show eruption problems of teeth, although in some cases, the primary failure of eruption (failure of the eruption mechanism itself) can be the primary cause. We have to know about the causes, differences, and the treatment modalities for those abnormalities.

This study explored how young people with disabilities experience self-determination in their lives. This study employed a grounded theory approach involving 10 undergraduate students with cerebral palsy or physical disabilities, in their early 20's, and individual interviews. The experience relating self-determination of the participants seemed to start with "wanting to do things at their will as they grow up". The participants reported experiencing "yearning to attain self-actualization overcoming disabilities" in the context of "disability-related social limitation", "divided opinions between the participants and their parents", and "limitation in financial and psychological resources". The emerging strategies to attain self-actualization included "active coping", "avoiding confrontation", and "conditional acceptance". Intervening conditions to formation of the strategies included ”challenging spirits towards prejudice about disability", "autonomous tendencies", "taking the most of social support" and "parenting attitudes of their parents". In the process of seeking to attain self-actualization, these participants experienced "self-maturation" and "the sense of guilt towards their parents". The findings emerged from the study was that there are three stages in the process young people went through in self-determination. The stages consist of "perceiving their needs and obstacles for self-determination", "problem solving", and "perceiving their growth". In addition, four self-determination patterns are derived from this data: "breaking through", "multi-strategic", "moderate", and "acceptive". This study suggested some theoretical and prctical implications needed to facilitate self-determination of youth with disabilities.

Purpose: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. Methods: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skinfold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. Results: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). Conclusion: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.

대주주들이 경영권을 직접 행사하고 있는 우리나라의 경영환경에서 기업의 의사결정은 대주주의 보유지분 정도에 따라 상당히 달라 질 수 있다. 즉, 소유경영자의 지분이 적으면 적을수록 경영자 자신의 이익과 전체 주주의 이익은 괴리되고 경영자의 경영상의 위험수용성(危險受容性)은 높아지게 된다. 이에 따라 내부지분율이 낮은 기업일수록 보다 높은 성장을 선호하고 위험성이 높은 투자대안을 선택할 가능성이 증대된다. 상기한 연구가설을 검정하기 위하여 94년부터 97년까지 4년간의 상장기업 자료를 이용하여 내부지분율과 부채비율, 그리고 성장률과의 관계를 분석하였다. 특히, 내부지분율을 포함하는 기업의 재무구조 다중회귀모형과 성장률의 다중회귀모형을 구축하여 내부지분율이 기업의 재무구조와 성장률에 대한 유의적인 설명력을 보유하고 없는지 여부를 검정하였다. 실증분석 결과는 내부지분율이 낮은 기업일수록 부채비율과 성장률이 상대적으로 높다는 연구가설을 일관성 있게 지지하고 있다. 이러한 연구결과는 정부의 기업정책에 대한 중요한 시사점을 던져주고 있다. 즉, 이제까지 기업들은 경영권에 대한 위협없이 내부지분율을 저하시킬 수 있었고, 이러한 상황에서 기업의 고부채, 고성장 전략은 소유경영자의 시각에서 볼 때는 극히 합리적인 것이었다. 하지만, 정부가 기업의 매수합병시장을 활성화시키면 많은 기업들은 경영권의 보호를 위해 내부지분율을 높이게 될 것이다. 이 경우 기업들은 보다 보수적인 경영을 하게 되어 부채비율은 낮아지고 과도한 성장정책은 지양될 것으로 예상된다. 따라서, 보다 건전한 기업경영을 유도하기 위해서는 내부지분율이 제고되어야 하고, 이를 위해서는 아직도 남아있는 매수합병의 장애요인들을 조속히 제거하는 것이 필요할 것이다.
