Eu sites and the effect of Mg codoping were investigated in Eu-implanted GaN films. Photoluminescence (PL) and PL excitation spectroscopies were performed on 620nm $^5D_0\;{\rightarrow}\;^7F_2$ Eu ionic level transition and revealed the existence of 4 different Eu sites including the known 2 sites. PL intensity from one of the sites increased by a factor of 1.6 by the Mg-codoping. The enhancement of PL by Mg-codoping was less pronounced than Er- and Nd-implanted GaN, in which the trap-mediated energy transfer dominates. In GaN:Eu the above-gap excitation transfers the energy directly to the Mg related Eu site. Eu을 이온주입한 GaN 시료에 대하여 Eu의 site들에 대한 연구와 Mg을 같이 도핑하였을 때의 효과를 분석하였다. 빨간색 광원으로 주목받는 620nm 근처의 Eu의 $^5D_0\;{\rightarrow}\;^7F_2$ 전이에 대하여 photoluminescence (PL) 와 PL 여기 분광법을 이용하여 GaN 내에서 Eu 이온이 자리하는 이미 알려진 2 개의 site 이외에도 2 종류의 site들이 있음을 확인하였다. 이들 중 한 site는 Mg의 codoping에 의하여 PL 크기가 약 1.6배 증가하였다. 이는 GaN의 밴드갭보다 작은 trap에 의해 에너지를 전달받는 Er이나 Nd보다 Mg의 도핑에 의한 효과가 매우 작은 것이다. GaN:Eu에서는 Mg과 관련된 trap을 통하지 않고 GaN에서 직접 Eu으로 에너지를 전달하기 때문으로 생각된다.

The purpose of this study is to analyze perceptions on the sexual relationship of middle-aged and elderly women. Though sex has been a critical theme of human-beings over their whole lifetimes, the previous studies have distinguished sex of the aged from the one of the middle-aged by focusing mainly on the physical aspects of sexual functioning. Viewing sex as a lifetime issue, this study implemented the qualitative analysis through the in-depth retrospective interviews on 12 middle-aged or elderly women. From this analysis 5 key categories were founded including ‘uneducated sex’, ‘time and place of communication’, ‘dynamics between sex actors’, ‘sustainability of sex’, and ‘sexual perception toward other generations’. The study results are followed : First, for both aged-groups the first experience of sex was unnatural and unfamiliar experience but pleasurable, so-called ‘uneducated’. Second, Although both aged-groups perceived sex as ‘time and place of private communication with their partners, the middle-aged showed less reluctance to express their sexual desire and denial than elderly women. Third, the middle-aged women pointed economic security as the most significant factor of sustaining sexual relationship while the elderly mentioned healthy functioning. Lastly, the elderly viewed sex as a whole lifetime story. These findings provoke implications in providing relationship-based interventions to family welfare practice along with the recognition of lifetime approaches with regard to sex of women.

남녀 노인의 생애주기별 성생활(sexual relationship) 인식의 변화

The purpose of this study is to analyze the changes of the perceptions on the sexual relationship among male and female elders through their whole lives. Though sex has been a critical theme of human-beings over whole their lifetimes, the previous studies on the sex of elders have distinguished the period of the aged from the time of pre-aged by focusing mainly on the physical aspects of sexual functioning. To view sex as a lifetime issue, this study implemented the qualitative analysis through the in-depth retrospective interviews on 10 male and female elders. The study results compared perceptions on the sexual relationship between male and female elders from early adulthood to the present elderly time. : First, while sex was unnatural and unfamiliar experience for female elders in their early adulthoods, it was a natural way to express sexual desires for males in their early adulthoods. Second, in the mid-time of the adulthood, the female elders retrospect this period as the best time of their sexual relationships with their sexual and emotional satisfactions, while male elders regarded sex as an approach to meet their natural desires. Third, in the later-time of the adulthood, females made extra efforts to overcome their decreasing sexual desires and satisfactions due to their menopauses, while males experienced the psychological conflicts between their physical functioning and sexual desires. Lastly, in the elderly time of their lives, males began to recognize self-reflections of the male-driven sexual relationship without considering their partners` emotions and desires, while females tried to keep their sexual relationships along with their partners` sexual patterns and paces. These findings provoke implications of the significance in relationship-based interventions and in the recognition of lifetime approaches with regard to sex of elders.

예비유아교사의 애착안정성 및 낙관성과 희망의 관계

이소원(Lee, So-won),문은식(Moon, Ehun-shik) 한국육아지원학회 2014 육아지원연구 Vol.9 No.1

본 연구는 예비유아교사가 지각한 애착안정성 및 낙관성과 희망의 관계가 어떠한가를 규명하기 위 해 수행되었다. 강원도의 K대학교, 경상남도의 I대학교, 충청남도의 H대학교 유아교육과 1, 2, 3, 4학년 여학생 382명을 대상으로 애착 검사, 낙관성 검사, 희망 검사를 실시하여 자료를 수집하였다. 자료분석 은 연구문제를 해결하기 위해 상관분석과 중다회귀분석을 실시하였다. 본 연구의 주요한 연구결과는 다음과 같다. 첫째, 어머니 애착은 희망의 총점과 두 개의 하위요인, 즉 주도사고 및 경로사고와 모두 유의한 상관이 있는 것으로 나타났다. 친구 애착은 희망의 총점, 주도사고 및 경로사고와 모두 유의한 상관이 있는 것으로 나타났다. 이는 예비유아교사의 어머니 및 친구 애착의 정도가 높을수록 그들의 희 망 정도도 높은 경향이 있음을 시사한다. 둘째, 낙관성은 희망의 총점, 주도사고 및 경로사고와 모두 유 의한 상관이 있는 것으로 나타났다. 이는 예비유아교사의 낙관성이 높을수록 그들의 희망도 높은 경향 이 있다는 것을 시사한다. 셋째, 희망 총점에 대한 애착과 낙관성의 상대적 영향력은 낙관성(β = .39), 친구 애착(β = .29) 순으로 나타났다. 그러나 어머니 애착은 희망 총점에 유의한 영향을 주지 않는 것으 로 나타났다. 이러한 결과는 예비유아교사의 희망을 촉진하는데 또래애착과 낙관성이 중요한 역할을 한다는 것을 시사한다. The purpose of this study were to investigate the associations between attachment security, optimism, and hope reported by pre-service kindergarten teachers, and to examine the relative influential power of their attachment security and optimism on hope. The tests of attachment scale, optimism scale, and hope scale were administered to 382 undergraduate students who were majoring in early childhood education from three different universities in Gangwon, Gyeongnam, and Chungnam province, Korea. The statistical methods for data analysis were correlation and multiple regression analysis. Results indicated that teachers' attachment to their mothers was positively and significantly related to their sense of hope. Teachers' attachment to friends was positively associated with their hope. The relations between optimism and hope was also positive. Finally, for the relative influential power of attachment and optimism on hope in pre-service kindergarten teachers, the most contributive variable to their hope was optimism (β =.39), and the next contributive variable was their attachment to friends (β =.29). However, teachers' attachment to mothers didn't have a significant influence on their hope. This study suggests that their optimism and attachment to friends can be significant variables for improving the hope.

Decompression sickness is a self contained underwater breath apparatus (SCUBA)-related injury with various symptoms and is considered an extreme emergency condition. This is a case of pulmonary involvement in decompression sickness in a 26-year-old SCUBA diver. Although pulmonary involvement in decompression sickness is a potentially severe condition that requires immediate treatment, this condition can be under- or misdiagnosed, and evaluation of this disease by imaging findings is not clearly understood. We experienced a case of pulmonry involvement in decompression sickness and herein present the chest computed tomography and simple radiograph findings associated with this condition.
