Objectives : This study was aimed to investigate stress and coping strategy in the families of schizophrenic patient, and changes of knowledge, stress and coping strategy after brief program of family education compared with control group Methods : The education group consisted of twenty four people who were families with schizophrenic patients and attended the brief program of family education. The control group consisted of twenty two people with schizophrenic inpatients. Self-report questionnaires such as Family Coping Questionnaire(FCQ), Patient Rejection Scale(PRS), Worry Questionnaire, Knowledge Questionnaire, Beck Depression Inventory(BDI), and State-Trait Anxiety Inventory(STAI) were administered to the education group and the control group, twice at the pre-test and post-test. Results : 1) In the education group, scores of worry questionnaire, BDI and STAI-S at the post-test were significantly lower than those at the pre-test. Social interests score of FCQ and knowledge questionnaire score at the post-test were significantly higher than those at the pre-test. In FCQ factors, social interests associated with avoidance strategy score at the post-test was significantly higher than that at the pre-test. However, in the control group, there was no significant difference in all questionnaires. 2) In the education group, significant positive correlation existed between calculated differences of worry questionnaire and STAI-S, and between worry questionnaire and STAI-T, whereas significant negative correlation existed between positive communication of FCQ and PRS, and between knowledge questionnaire and STAI-S. In the control group, significant negative correlation existed between information of FCQ and PRS, and between positive communication of FCQ and PRS. 3) In the education group, significant positive correlation existed between calculated differences of worry questionnaire and age of patient, whereas significant negative correlation existed between knowledge questionnaire and duration of illness. However, in the control group, there was no significant correlation. Conclusion : The brief program of family education was effective in increasing knowledge about schizophrenia, decreasing worry and anxiety about the patients in families with schizophrenic patient. In the education group as knowledge about schizophrenia increased, anxiety about schizophrenic patient decreased, but there was no significant correlation in the control group. As relative's rejection feeling about schizophrenic patient decreased, positive communication strategy increased in both groups. However, the control group was more affected by rejection feeling than the education group.

This study examined the possibility of solving the water shortage problem through the water reuse of buildings through the Suwon water reuse (greywater) facility installation project conducted as a pilot project of Ministry of Environment. Water reuse of individual building units can reduce city water demand by up to 25%. This is a level that can solve the water shortage problem in Korea. However, in order to revitalize the water reuse facilities of individual buildings, it is necessary to solve the problem of the user's rejection of the greywater and the economical problems. The resolution of the user's rejection can be solved by linking the MBR process with the AOP process. When the MBR process and the AOP process are operated in conjunction with each other, it is found that the users do not feel the water quality difference with the tap water. Economical problems can be solved at the water rate levels when the facility capacity is over 100 ton/day considering the construction cost and the operation cost, and when the operation cost alone is over 15 ton/day. Furthermore, when considering the social benefit cost, it is found that profit is generated from 150 ton/day.

This study verified the effectiveness of brief family education programs for schizophrenic outpatients and their families in a community social welfare center, using a pre - post test control group design. The results of this study verified that the program was effective to improve knowledge about schizophrenia, reduce feelings of rejection and anxiety about patients, and help the patients to recognize their family emotional support. Therefore, it was found in this study that the brief family education program in the community social welfare center had a positive impact on schizophrenic outpatients and their families' treatment and rehabilitation. From the results of this study, it can be seen that this program positively effects the treatment and rehabilitation of schizophrenic patients and the stability of their families. The program can also be easily utilized as a community resource. Furthermore, the results of this study can be utilized as fundamental support to suggest the need for mental health programs in community social welfare centers. This study suggested the importance of increasing the number of mental health professionals working in this arena. There is also a need to create additional supportive programs for schizophrenic outpatients and their families. Follow up care also needs to be provided to families after completing family education programs. Continuous study is needed in these areas.

수자원의 효율적 이용 및 관리는 심화되고 있는 기후변화에 선제적으로 대응하고 발생가능한 물위기에 대비하기 위한 필수조건이다. 그 중 가장 핵심이 되는 요소는 댐에 저수된 물을 효과적으로 이용하는 것, 즉 댐 건설목적에 따라 시간 및 공간별로 적절하게 할당시키는 것이라고 할 수 있다(Kim, 1998). 그러나 단일 댐의 운영과는 달리 수계내 댐군의 연계 운영은 매우 복잡하고 어려운 문제이다. 연계된 댐들간 저수 상황을 고려하여 유역내 시 공간적인 용수 수요의 지속적인 충족을 위하여 유입량 예측의 정확성을 높이도록 하고, 상류 댐에 최대한 저류하도록 하며, 여수로 방류 같은 불필요한 방류를 최소화 하고, 서로 상충되는 목표를 갖고 있지만, 홍수용량 및 발전수위를 최대로 확보하도록 하여야 한다. 이처럼 댐 운영을 위한 실제 상황은 단일 목적에 의한 최적화와는 달리 여러 상충되는 목적 및 구성 요소들간의 타협, 조정을 필요로 한다. 댐군의 연계운영 문제는 1960년대 초부터 현재까지 활발히 연구가 진행되어 온 분야 중 하나이나 문제의 복잡성과 어려움으로 인해 아직까지도 최선의 방안을 제시하기 어려운 문제이다(ReVelle, 2000). 이를 위한 방법은 시뮬레이션 모형 활용기법과 최적화 모형 활용기법으로 대별할 수 있으며 각 방법의 서로 다른 구조적 특성과 장단점으로 인하여 이원화된 체계로 사용되는 것이 현재의 국내 실정이다. 대부분의 실무에서는 이해도도 쉽고, 비교적 결과를 빨리 도출할 수 있는 시뮬레이션 기반의 모형을 활용하며 대표적으로 HEC-5, K-ModSim, HEC-ResSim 등이 활용되어왔다. 반면, 학계에서는 DP, MIP, SLP, SDP 등 최적화기법을 댐운영에 활용 할 것을 제안하고 있지만, 활용에 대한 거부감이 남아있는 것이 현실이다. 본 연구에서는 시뮬레이션과 최적화기법의 원론적 비교를 통해 각 방법의 장단점과 한계점을 분석하고, 왜 이원화된 사용체계로 되었는지에 대한 고찰과 이에 대한 해결책으로 시뮬레이션모형의 장점과 최적화기법의 장점을 결합한 모형을 제안한다. 국내에는 Kim and Park(1998)이 시뮬레이션 기반의 최적화 모형 CoMOM(Coordinated Multi-Reservoir Operating Model)을 개발하였으며, 이후 21C프론티어 연구사업(2001-2011)에서 모형의 보완수정 검증을 통해 실무 활용도를 높여 왔다. 본 연구를 통하여 거부감의 원천을 추적해 보고, 타당한 이유가 있는지 대한 것을 심층 분석해보고, CoMOM모형과 시뮬레이션 모형, 다른 최적화 기법들과의 원론적 비교를 통해 각 방법들의 효율적인 활용방안과 최적화모형의 구체적인 활용방안을 제시하고자 한다.

In order to overcome the disadvantages of banner ad, pop-up ad, interstitial ad, which are existing web advertisement forms, native ad is actively utilized. Native advertising is considered to be a useful advertising technique in that it can reduce users' rejection and attract attention. However, in recent years, there have been a lot of fake news and fake contents that have turned articles or video contents into advertisements. The purpose of this study is to understand how firms can coordinate and control native advertisements in a rational way. For this analysis, we conducted a survey of 308 social media users using quota sampling method. As a result of the verification, it was found that the more negative the perception of the evaluation of the advertisement, the less the level of persuasion about the advertisement and the negative impact on the website where the advertisement is exposed. In addition, this study examined the influence of the negative stimulus factors on the qualitative performance of the firm. As a result, it was found that source non-expert had the highest effect on skepticism on ad. Also, platform overflow has a direct effect on the evaluation of the website as well as the negative evaluation of the advertisement. Moreover, this study provides concrete implications for the subdivision market by verifying the differences between the paths according to the level of website involvement.

This study examines factors that influence delinquent behavior among Korean adolescents using longitudinal analysis. A total of 1,012 students completed a questionnaire when they were Grade 6 and 739 students completed a follow-up questionnaire when they became Grade 9. Results of multiple regression analysis indicate that the following variables predicted delinquent behavior of Grade 9 students: Bullying, previous delinquency, experience of punishment, victimization, social efficacy, and moral disengagement. The above six variables have direct and mediating influence of delinquent behavior. Relational factors also influenced delinquent behavior. Social exclusion from friends reduce social efficacy, which increases victimization and which in turn increases bullying, leading to greater delinquency. Parental rejection, social exclusion from friends and hostility from teachers increase moral disengagement, which increases bullying, leading to delinquency. Low academic achievement increases the likelihood of being punished, which increases bullying, leading to delinquency. The results indicate that moral disengagement and social efficacy are mediating factors of delinquency and negative life-events (i.e., social exclusion from friends, rejection from teachers, hostility from parents and low academic achievement) increase the likelihood that Korean adolescents will engage in delinquent behavior. Implications of the results for future research are discussed.

This study analyzes the impact of the experiences of elderly using social welfare organizations in socio-economic deprivation on their relational aggression damage experiences, and verifies the mediating effects of rejection sensitivity. For data collection, 275 of 290 questionnaires, excluding 15 questionnaires with inadequate responses, were used for the final analysis. The SPSS and AMOS programs were used for data analysis through the following procedures. The analysis showed that socio-economic deprivation experiences, relational aggression damage experiences, and rejection sensitivity were higher for the groups of male elderly, higher age, education above college, absence of spouse, and longer institutionalization. The size of indirect effect (${\beta}=.32$) was larger than that of direct effect (${\beta}=.14$), signifying that the indirect impact through rejection sensitivity was larger than the impact of socio-economic deprivation on the experiences of damage by relational aggression. With the above findings, this study makes practical suggestions for institutional measures to reduce the elderly's relational aggression damage experiences and rejection sensitivity and programs on socio-economic deprivation, etc.

The purpose of this study was to examine the relationship pattern among paternal parenting behaviors, father involvement, parenting stress, and parenting self- efficacy. The subjects were 299 fathers of 3 to 4 year-old children at 2 child care centers and 11 kindergartens in Seoul and the Gyunggi-do area. Fathers responded to a modified version of Parenting Daily Hassles(Crinc & Greeberg, 1990), a re vised version of Parenting Sense of Competence(Gibaud-Wallston & Wandersman, 1978), and questionnaires including questions about parenting behaviors(Park, 2000) and father involvement developed by authors. Stepwise regression analyses showed that fathers' cognitive efficacy of parenting and the frequency of play involvement on weekdays significantly explained paternal 'warmth encouragement'. Also, cognitive efficacy and the frequency and time amount of play involvement on weekdays significantly explained paternal 'setting up the limitations'. Meanwhile, fathers' emotional efficacy and the amount of play time involvement on weekdays significantly explained paternal 'over-protection permission'. Finally, the cognitive and emotional efficacy of rearing and parenting stress significantly explained paternal 'rejection non-intervention'.

This study is to examine the effects of smartphone addiction on the mothers' parenting efficacy and parenting attitude. This study consisted of 203 smartphone using mothers of preschoolers in Gyonggi-do. The measurements included smartphone addiction scale(National Information Society Agency, 2011), the parenting efficacy scale(Choi & Chung, 2001), and the parenting attitude scale(Bae, 2005). Theses analyses were included in the Pearson correlation coefficient, the T-test, and the Hierarchical regression analysis. The findings indicated that the younger mothers showed higher levels of smartphone addiction. The results of smartphone addiction subscales on parenting efficacy indicated that the disturbance of adaptive functioning was related with general parenting ability, healthy parenting ability, communication ability, and learning guidance ability. The results of smartphone addiction subscales on parenting attitude showed that the disturbance of adaptive functioning was positively related with rejective parenting attitude and virtual life orientation was negatively associated with affective and autonomous parenting attitude. These findings can emphasize parents' appropriate smartphone use, and be useful resources to develop and utilize the programs of positive parenting efficacy and parenting attitude.

본 연구에서는 실감공간에 대한 청소년의 반응을 바탕으로 향후 기술 개발 방향에 대한 조언을 하기 위하여 총 41명의 학생을 대상으로 소집단 포커스 그룹 인터뷰를 시행하였다. 청소년들이 자주 사용하는 미디어의 종류와 이유, 미디어 사용에서 느끼는 불편한 점, 그들이 상상하는 미래형 미디어의 모습과 실감공간기술에 대한 반응을 묻고, 그 결과를 유형화하였다. 연구 결과 포커스 그룹 인터뷰 참가자들은 자주 사용하는 미디어로 휴대폰과, 인터넷, MP3, 활자 매체 등을 꼽았다. 활자매체의 장점으로는 높은 몰입도를, 인터넷의 장점으로는 편리한 인터페이스, 핸드폰의 장점으로는 이동성이 제기되었다. 그러나 핸드폰과 관련하여 청소년들은 불편한 인터페이스, 작은 용량과 빨리 닳는 배터리를 단점으로 지적했고 뉴미디어 공통적으로 느린 속도, 미디어에 의존하게 되는 강박증적 증세, 사생활 침해의 문제와 대인관계유지에 있어서의 부작용, 높은 이용료 등의 문제가 제기되었다. 이들은 일상생활이 미디어 이용에 의해 방해받고 있으며 미디어 이용으로 인해 불필요한 '필요'가 생겨나고 있다고 지적했다. 미래형 미디어에 대한 바람은 기존 미디어의 단점이 보완, 개선되는 측면에서 제시되었다. 더욱 편리해진 인터페이스와 기존 뉴미디어의 장점이 접목되는 방향의 미디어 통합도 요청되었다. 그러나 실감공간기술에 대해서는 긍정적인 반응보다는 부정적인 반응을 수적으로 우세해 주목을 끌었다. 진화된 형태의 미디어에 대해 긍정적인 반응을 보일 것이라는 예상과는 달리 실감공간기술이 기존의 면 대 면 대인관계를 파괴할 것이며 사생활을 침해하고 건강에 부정적인 영향을 미칠 것이라는 등의 거부감과 공포를 구체적으로 피력한 것이다. 이러한 두려움(fear)은 선행연구에 따르면 사람들이 새로운 매체에 대해 갖는 두려움과 이로부터 발생하는 두려움에 대한 대응은 혁명적 변화의 가능성을 억압하여 기존의 질서와 새로운 질서가 공존하는 기간을 늘림으로써 미시적 차원에서 단절적 역사의 경험을 완화시키는 기능을 하는 것으로 해석된다. 따라서 연구 결과 나타난 실감공간 기술에 대한 부정적인 반응도 이러한 맥락에서 해석될 수 있다. 즉 인터뷰 참가자들이 피력한 두려움은 뉴미디어 도입과 함께 반복되는 현상이며 이것은 새로운 현상이 아니다. 두려움은 기존 질서와 새로운 질서가 공존하는 기간을 연장시킴으로써 완충재로서 기능한다. 따라서 향후 기술 개발과 확산 과정에서 실감공간기술의 긍정적인 면모에 대한 적극적인 홍보가 필요하며 수용자들의 바람과 신기술에 대한 공포감을 이해하고 이를 기술 개발 방향 설정에 적극적으로 반영하는 자세가 요청된다고 하겠다.
