  • 전 세계적으로 인공습지는 도시화, 기후변화 및 생활수준 향상으로 인한 홍수와 가뭄, 하천생태계 변화, 수질오염과 같은 환경문제의 해결방안으로 제시되고 있다. 이에 따라 국내에서도 여러 목적과 형태의 인공습지가 조성되고 있다. 인공습지의 경우 특정 기능을 목적으로 하여 조성하더라도 인공적 생태계가 조성되므로 복합적 기능을 갖게 된다. 하지만 현재까지의 인공습지 조성 효과에 관한 연구는 한가지 기능에만 초점을 맞추어서 실제 인공습지 조성의 가치가 저평가되고 있다. 본 연구에서는 하천변 인공습지 조성에 따른 여러 효과 중 가장 주가 되는 홍수저감 및 수질개선 기능에 대한 효과를 분석하고 이에 따른 편익을 산정하였다. 먼저 인공습지의 적용 대상 유역을 선정하고 유역 내에 입지를 결정하여 이에 맞는 인공습지를 설계 및 적용하였다. 인공습지 조성에 따른 홍수저감 효과 및 수질개선효과를 각각 분석하였다. 분석 결과에 대해 MD-FDA를 통해 홍수피해액을 산정하였고 대체비용법을 통하여 동일한 수질개선 효과를 갖는 하수처리시설의 하수처리비 및 운영관리비에 해당하는 수질개선 편익을 산정하였다. 본 연구를 통해 인공습지의 홍수저감 효과뿐만 아니라 수질개선 효과를 확인하였으며 정량적인 분석방법을 통해 두 가지 기능에 대한 효과를 분석하여 보았다. 또한 산정된 홍수저감 및 수질개선 효과를 경제적 가치로 환산하여 보다 객관적인 지표로 나타내었다. 본 인공습지 조성에 따른 종합적 편익 산정 연구 결과는 다목적의 인공습지를 적재적소에 적용하는데 기여할 것이다. 추후 생태적 기능, 레크레이션 기능 등에 따른 기타 편익 산정 방법론 조사를 통해 각 기능의 편익을 추가한다면 인공습지 조성에 따른 편익을 종합적으로 고려할 수 있을 것으로 판단된다. 또한 인공습지 조성의 소요사업비 및 유지관리비를 산정하여 인공습지 조성에 대한 경제성분석을 한다면, 실제 인공습지 조성 사업 시 사업의 타당성을 평가하는 기초자료로 활용할 수 있을 것으로 기대된다.

  • This study is about how functional conflict, hierarchical conflict in child-care centers and the sociology population of teachers influence organizational effectiveness. The questionnaire listed about the organizational conflict and the organizational effectiveness were used in this study. For the analysis of the questionnaire, frequency, percentage, reliability, and regression were used as statistical tools. In the results, the teacher's academic backgrounds, career, and marital status seem to have an influence on the organizational conflict. The hierarchical conflict in child-care centers has a more negative influence on organizational effectiveness than the functional conflict.

  • The purpose of this study is to verify whether education on the placebo effect has significant impacts on the knowledge of the placebo effect, as well as the intention of healing food intake. For this purpose, 37 experimental group students and 29 control group students participated in the experiment. The results were as follows. First, education on the placebo effect did not appear to have significant impact on the functional value although it did have significant impact on emotional value and nutritional value. Second, knowledge of the placebo effect gained from the education had significant influence on intention of healing food intake. Third, only nutritional value showed a statistically positive (+) impact on intention of healing food intake.

  • The purpose of this study was to identify the impact of chewing ability on cognitive function of older people in Korea and the mediation effect of physical function and depression using the nationwide data from "Survey of the Living Conditions and Welfare Needs of Korean Older Persons in 2014", in Korea. This study was conducted on a total of 10,451 respondents in the "Survey of the Living Conditions and Welfare Needs of Korean Older Persons in 2014" and the data collection period was from June 11, to September 4, 2014. Chewing ability was used in the scale on level of daily life inconvenience in chewing ability (meat or hardness). Cognitive function was measured using MMSE-DS, physical function using K-IADL, and depression using SGDS-K. The data were analyzed using the SPSS 24.0 program and Process Macro. Total effects of chewing ability on cognitive function were not significant(p>.05). Direct effects of chewing ability on cognitive function were not significant(p>.05). There were the dual mediation effect(p<.05) of physical function and depression, a complete mediating effect by physical function(p<.05) or depression(p<.05) in the impact of chewing ability on cognitive function of older people in Korea. These results indicate that physical function and depression effect directly and indirectly in the impact of chewing ability on cognitive function of older people. In conclusion, it is suggested that to prevent the decline of cognitive function in older people, it is necessary to consider not only nursing strategies for strengthening chewing ability and physical function, but also nursing interventions for relieving or preventing depression in older people.

  • The paper evaluated the effects of port hinterlands and suggested the policies to improve them in Korea. The results of evaluation indicated that it is difficult for the effects to be evaluated so good. It seems that a lot of efforts should be made to make port hinterlands carry out their own functions well, in that, in particular, they have had so bad effects in carrying out such functions as production, international trade, and city. Policy actions were suggested including reduction of rent, strengthening international logistics networks, and governmental funding etc.

  • The purpose of this study was to examine the mediating effect of functional and dysfunctional expressions of anger on the relationship between covert narcissism and dating violence among college students. The study also investigated gender differences with regard to covert narcissism, dating violence, and functional and dysfunctional expressions of anger. To this end, 339 college students (133 males, 206 females) with heterosexual dating experiences in the Busan Metropolitan area were recruited. They responded to the Covert Narcissism Scale, the Revised Conflict Tactics Scale 2, and the Korean adaptation of the State-Trait Anger Expression Inventory. The results were as follows. First, covert narcissism, dating violence, and functional and dysfunctional expressions of anger differed significantly by gender. Second, there were statistically significant correlations between covert narcissism, dating violence, and functional and dysfunctional expressions of anger. Third, multiple regression analysis showed that dysfunctional expressions of anger for males were positively correlated with dating violence while functional expressions of anger were negatively correlated. For females, dysfunctional expressions of anger were positively correlated with dating violence while functional expressions of anger were not significantly correlated. Fourth, dysfunctional expressions of anger completely mediated the relationship between covert narcissism and dating violence for both males and females, but functional expressions of anger had no mediating effect. These results suggest that dysfunctional anger expression control program should be developed for students which may help those with covert narcissistic tendencies to functionally express their anger. Future research should analyze dating violence prevention and counseling programs.

  • With the increasing popularity of computer games as a leisure activity, there has been a rise in the interest in the effectiveness of serious games. Many of the earlier researches are focused on evaluation of effects, types, developments of serious games, whereas little is known about the after effects of serious games. The aim of this paper is to examine the previous literatures on serious games in regard to their impacts and outcomes of gaming for the purpose of empirical evidence as impacts and outcomes are needed for exploratory study of variable outcomes of educational serious games. It is worth noting that current review would be used as an outcome indicator for verifying the after effects of both cognitive and educational after the usage of these educational serious games.

  • 본 연구에서는 사이버가정학습을 교사가 교실 수업과 사이버가정학습 시스템을 연계하여 운영함에 있어 어떤 요인이 사이버가정학습에 대한 학습자 만족에 영향을 미치는지를 분석하였다. 기술수용모형을 기반으로 Y초등학교 5학년 학생들을 대상으로 6개월간 운영한 후 설문조사를 실시하였다. 분석결과 초등학생들에게 사이버가정학습 만족도는 지각된 유용성과 용이성에 의하여 결정되는 것으로 나타났으며, 자기주도적 학습 능력과 학습결과보상기능은 사이버가정학습을 긍정적으로 수용할 수 있는 유용성에 상당한 영향을 미치는 중요한 요인으로 작용하는 것으로 분석되었다. 만족도에 영향을 미칠 것으로 예상했던 교육적 효과, 콘텐츠 품질은 만족도를 직접적으로 유발시키는 본질적인 요인이 아님을 알 수 있었다. 학습지원기능, 시스템 안정성 및 편리성, 상호작용 등 시스템적인 기능이 만족도에 유의미한 영향을 미치지 못하는 것으로 나타났다. 이 요인들은 단지 콘텐츠의 품질을 향상시키는 효과를 가지며, 이 효과를 통해 교육적 효과를 강화시키는 역할을 수행하는 것으로 분석되었다. 따라서 학습을 지원하는 기능, 시스템 안정성 및 편리성, 선생님과 학생 또는 학생 간의 상호작용이 가능하도록 지원하는 모든 시스템적인 기능은 수강생의 만족도에 직접적인 영향을 미치거나 만족을 이끌어 낼 수 있는 본질적이고 핵심적인 요인이 아님을 알 수 있다.

  • The present study investigated the related variables of cognitive function, subjective cognitive decline and cognitive training effects. The cognitive training was composed of mete-cognitive education and cognitive task performing. Twenty older adults attended for 14 weeks and were tested before and after the training. Results show that their cognitive level was related with age, self-esteem and personality traits. And subjective cognitive decline was related depression, anxiety, personality traits, self-efficacy, self-esteem and subjective age, but it does not reflect objective cognitive impairments. Their cognitive test scores were enhanced after training in MMSE, memory and executive function, and enhanced scores were related with age, subjective cognitive decline, anxiety, self-efficacy, self-esteem, subjective age and personality traits. Findings suggest one's personality and psychological state need to be considered for the effects of cognitive training.
