The impact of childhood experience has lifelong significance on subsequent health and development. Especially, the experience of infant is mostly affected by the quality of parental care and rearing environment. But the new mothers usually do not know what to do because of the lack of experience in these days. Therefore, an educational program regarding maternal role would be necessary. This study was conducted to evaluate the effectiveness of the maternal role education program for mother-infant interaction, child-rearing environment, and infant development. Non-equivalent control group time-series design was used, and Barnard's mother-infant interaction model was used as a conceptual framework of this study. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37 weeks, and their mothers. The final sample consisted of 19 mother-infant dyads for intervention group and 18 dyads for control group. Data were collected from March 15th to September 3rd in 1999. For the intervention group, programmed education which focused on mother-infant interaction, breast feeding, and infant care was provided before discharge. Telephone counselling was provided within one week after discharge. Home visiting for maternal role education was provided twice, one month and three months postpartum. For the control group, home visiting was also conducted but only for data collection. The data were analyzed using chi-square test and t-test to test the equivalence of two groups, and the effectiveness of intervention program was determined with repeated measure ANCOVA and t-test. The results were as follows: 1. Significant differences were found in mother-infant interaction between two groups(p=.000). It indicates that intervention program was effective in improving mother- infant interaction. In subscale analysis, four out of six subscale showed significant differences between the groups: sensitivity to cues (p=.000), social-emotional growth fostering (p=.000), cognitive growth fostering(p=.000) in mothers, and responsiveness to caregiver (p=.019) in infants. 2. The difference in the mean score of childrearing environment (HOME) between the intervention group and control group was significant(p=.003). When each subscale of HOME was examined individually, intervention group showed significantly higher scores in the diversity of stimulation(p=.000), and mother's involvement(p=.001). 3. Three-month-Infants of the intervention group showed higher GQ in the Griffiths mental development scale(p=.026). In subscale analysis, significant differences were found in the personal-social(p=.005), and the hearing and speech(p=.003). In conclusion, the maternal role education program proved to be effective in promoting the mother-infant interaction, organizing the childrearing environment, and fostering the infant development. These results are very meaningful that we found maternal role education necessary for normal infants' mothers, and that nurses can make a great contribution in promoting health of infants and mothers.

Recent research indicates that the new mothers want to learn about childrearing, and have burden in care of infants. Also it indicates that the new mothers say the lack of confidence and knowledge about infant care. This study was a prospective longitudinal reseach developing parent role education program and evaluating the effectiveness of this program for mother-infant interaction, childrearing environment and infant development. Longitudinal quasi-experimental design was used. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their mothers. The sample consisted of 19 mother-infant dyads for intervention group and 18 dyads for control group. Data were collected from March 15th to December 14th in 1999. For the intervention group received programmed education that was consisted of discharge education, telephone counselling, and home visiting for maternal education. The data were analyzed using chi-square test and t-test to test the equivalence of two groups, and the effectiveness of intervention program. This study was focused on the results of six months time point. The results were as follows: 1. There was significant difference in the mean score of mother-infant interaction(NCAST) between two groups. Intervention group showed higher scores in the subscales of sensitivity to cues, cognitive growth fostering, and caregiver total. 2. There was no significant difference in the mean score of child rearing environment (HOME) between two groups of six-month-infants. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of opportunities for variety in daily stimulation, maternal involvement with child, and emotional, verbal response. 3. Six-month-infants of the intervention group showed significantly higher GQ in the Griffiths mental development scale. In conclusion, the maternal education program was effective in promoting the mother-infant interaction, organizing the childrearing environment, and fostering the infant development. These results were very meaningful that we found parent role education necessary for normal infants' mothers, and nurses can make a great contribution in promoting health of infants and mothers.

우울증은 우울한 기분, 무쾌감증, 피로 및 인지 기능 변화를 특징으로 하는 정신질환으로 일상 기능의 저하를 초래한다. 또한, 우울증은 개인의 삶뿐만 아니라 사회적으로도 심각하고 흔한 정신질환이므로 적극적인 치료가 필요하다. 자가소화작용은 정신질환의 병태생리학적 기전에 관여한다. 최근 연구에 따르면, 자가소화작용에 의한 세포사멸이 신경가소성에 영향을 주어 우울증을 유발하고, 항우울제가 자가소화작용을 조절한다고 알려져 있다. 자가소화작용은 용해소체를 통해 불필요한 세포소기관이나 단백질을 분해하고 제거하는 이화과정이다. 그리고, 세포의 항상성을 유지하는데 필수적이다. 자가소화작용은 스트레스 상황에서 활성화되며 우울증은 스트레스 관련 질병이다. 최근, 신경세포에서 자가소화작용 기전의 역할이 조사되고 있지만, 우울증의 자가소화작용은 완전히 연구되지 않았다. 이 리뷰에서 우울증의 병태생리학적 기전과 치료에 자가소화작용이 관여한다는 새로운 증거를 강조하고자 한다. 증거를 강조하기 위해 자가소화작용이 우울증과 관련되어 있음을 보여주는 임상 및 전임상 연구결과들을 소개한다. 우울증에 대한 자가소화작용의 관련성과 연구의 한계를 이해하는 것은 자가소화작용 조절이 항우울제 개발의 새로운 방향을 제공할 것으로 사료된다.

본 연구는 개별 소비자가 구매를 결정하는데 있어 중요한 요소라고 할 수 있는 신뢰가 전이되는 현상을 실증적으로 확인하고자 한다. 많은 선행연구에서 신뢰가 전이되는 과정에 관한 언급은 있었지만, 이에 대한 실증적 연구가 부족하였다. 본 연구는 특히 유통업체에 대한 신뢰가 전이되는 현상에 초점을 맞추었으며, 신뢰 전이의 대상으로 PL(Private Label) 제품을 선정하였다. PL제품은 유통업체에서 판매되는 제품들 중 신뢰가 전이됨에 있어 기본 가정이 되어야 하는 평가대상의 애매 모호성이라는 특성을 갖기 때문이다. 또한 PL제품 자체가 제조업체 브랜드 제품에 비해 상대적으로 적은 정보를 제공하고 있기 때문에 본 연구의 대상으로 적합하다고 판단되었다. 게다가 최근 유통업체는 PL제품의 판매영역을 늘리고 있다. 먼저 저자들은 선행연구가 가지고 있는 이론적/실증적 한계점을 극복하기 위한 신뢰의 전이 현상을 설명하는 이론으로, 인지적 신뢰의 전이에 있어서는 '균형이론'과 '가용성 간편추론법'을 근거로 들었다. 또한, 감정적 신뢰에 있어서는 '감정전이'와 '정보로서의 감정'이라는 2가지 이론적 근거를 제시함으로써 선행연구들을 보완하였으며, PL제품 구매자 206명을 대상으로 실증분석을 실시하였다. 분석 결과, PL제품을 구매하는데 있어, 신뢰의 전이 현상이 나타남을 매개효과를 통해 확인할 수 있었다. 비록 매개효과를 포함한 제안모델이 매개효과가 없는 모델과 비교해서 그 모델 적합도가 크게 개선되지는 않았으나, 각각의 경로계수가 매개효과가 없는 모델에 비해 향상되어 매개효과가 있음을 확인할 수 있었다. 또한 신뢰의 2가지 차원인 인지적 신뢰와 감정적 신뢰에 있어서, 인지적 신뢰는 PL제품의 제조업체 및 제품 자체에 대한 신뢰로 전이되는 것을 확인할 수 있었으나, 감정적 신뢰에 있어서는 PL제품의 제조업체에 대한 신뢰의 전이가 나타나지 않는 것으로 나타났다. 이는 감정적 신뢰는 직접적인 경험에 근거하여 형성되는 것으로, PL제품은 유통업체 브랜드와 같은 브랜드 이름을 사용하고 많은 상품군을 갖고 있기 때문에 소비자에게 많이 노출되어 친숙함과 같은 감정적인 부분이 개입될 가능성이 있지만, 이와 달리 제조업체와는 감정적 신뢰가 전이될 만한 직접적인 경험이 없었기 때문이라 판단된다.

일화기억은 핵심 이벤트와 그에 연합된 맥락으로 구성된다. 해마와 해마 주변 영역이 일화기억의 부호화에서 맥락을 표상하는 역할에 관해 연구되어왔지만, 시공간적 맥락 외에 다양한 맥락-특이적 정보들에 대한 표상에 관한 연구는 많지 않다. 본 연구에서는 고해상도 자기기능공명기법을 이용하여 여러 맥락정보(예, 육하원칙 - 누가, 왜, 무엇을 언제, 어디서, 어떻게)의 부호화에 관여하는 내측두엽 및 대뇌피질 신경연결성의 특징을 탐색하였다. 참가자들은 두 명의 얼굴과 하나의 사물로 구성된 실험 이벤트를 보면서 여섯가지 맥락 부호화 과제를 수행하였다. 휴지기 기능적 자기공명영상 정보를 활용해 내측두엽의 세부 영역을 기능적으로 구분하였고 맥락 기억 과제별 기능적 신경연결성 네트워크를 탐색하였다. 일반선형화 모델 분석을 통해 시공간적 맥락정보를 처리할 때보다 사회적, 행동적, 의도 맥락을 연합할 때 내측두엽의 세부영역, 전전두엽, 하부두정엽 영역이 유의미하게 증가한 활성화를 보이며 관여함을 확인하였다. 나아가 이 영역들과 내측두엽 영역이 맥락조건간 차이에 관여하는 기능적 연결성 특징을 탐색하기 위하여 맥락부호화 과제를 수행하는 동안의 해마세부영역들과 전전두엽, 하부두정엽 등 간의 과제기반 기능적 연결성 정보들을 다변량 패턴분석의 주요입력변수로 선정하였고, 기계학습을 통해 맥락 조건 간 연결성 패턴분류를 시도하였다. 네트워크 패턴분류에서도 시공간 맥락 조건과 각 사회적, 행동적, 의도 맥락처리 조건 간에는 기능적 연결성의 차이가 두드러졌다. 본 연구결과를 통해 일화기억에서 특정 맥락을 처리하는 신경학적 기제의 특성과 맥락 조건 간 차이를 제시하였다.

Within the traditional medical delivery system, patients residing in medically vulnerable areas, those with body movement difficulties, and nursing facility residents have had limited access to good healthcare services. However, Information and Communication Technology (ICT) provides us with a convenient and useful means of overcoming distance and time constraints. ICT is integrated with biomedical science and technology in a way that offers a new high-quality medical service. As a result, rapid technological advancement is expected to play a pivotal role bringing about innovation in a wide range of medical service areas, such as medical management, testing, diagnosis, and treatment; offering new and improved healthcare services; and effecting dramatic changes in current medical services. The increase in aging population and chronic diseases has caused an increase in medical expenses. In response to the increasing demand for efficient healthcare services, a telehealth service based on ICT is being emphasized on a global level. Telehealth services have been implemented especially in pilot projects and system development and technological research. With the service about to be implemented in earnest, it is necessary to study its overall acceptance by consumers, which is expected to contribute to the development and activation of a variety of services. In this sense, the study aims at positively examining the structural relationship among the acceptance factors for telehealth services based on the Technology Acceptance Model (TAM). Data were collected by showing audiovisual material on telehealth services to online panels and requesting them to respond to a structured questionnaire sheet, which is known as the information acceleration method. Among the 1,165 adult respondents, 608 valid samples were finally chosen, while the remaining were excluded because of incomplete answers or allotted time overrun. In order to test the reliability and validity of the assessment scale items, we carried out reliability and factor analyses, and in order to explore the causal relation among potential variables, we conducted a structural equation modeling analysis using AMOS 7.0 and SPSS 17.0. The research outcomes are as follows. First, service quality, innovativeness of medical technology, and social influence were shown to affect perceived ease of use and perceived usefulness of the telehealth service, which was statistically significant, and the two factors had a positive impact on willingness to accept the telehealth service. In addition, social influence had a direct, significant effect on intention to use, which is paralleled by the TAM used in previous research on technology acceptance. This shows that the research model proposed in the study effectively explains the acceptance of the telehealth service. Second, the research model reveals that information privacy concerns had a insignificant impact on perceived ease of use of the telehealth service. From this, it can be gathered that the concerns over information protection and security are reduced further due to advancements in information technology compared to the initial period in the information technology industry, and thus the improvement in quality of medical services appeared to ensure that information privacy concerns did not act as a prohibiting factor in the acceptance of the telehealth service. Thus, if other factors have an enormous impact on ease of use and usefulness, concerns over these results in the initial period of technology acceptance may become irrelevant. However, it is clear that users' information privacy concerns, as other studies have revealed, is a major factor affecting technology acceptance. Thus, caution must be exercised while interpreting the result, and further study is required on the issue. Numerous information technologies with outstanding performance and innovativeness often attract few consumers. A revised bill for those urgently in need of telehealth services is about to be approved in the national assembly. As telemedicine is implemented between doctors and patients, a wide range of systems that will improve the quality of healthcare services will be designed. In this sense, the study on the consumer acceptance of telehealth services is meaningful and offers strong academic evidence. Based on the implications, it can be expected to contribute to the activation of telehealth services. Further study is needed to assess the acceptance factors for telehealth services, such as motivation to remain healthy, health care involvement, knowledge on health, and control of health-related behavior, in order to develop unique services according to the categorization of customers based on health factors. In addition, further study may focus on various theoretical cognitive behavior models other than the TAM, such as the health belief model.
