In the modern society, as development innovative technology consumers could access various information. It make consumers empower in the market, and information asymmetry problem were solving more and more. In the technical information, however, there are still information asymmetry because technical information is very difficult to understand, and those are related with professional knowledge such as financial information. This study used the dataset which was collected to track Korean consumers consumption index by KCA(Korea Consumer Agency) which included consumer's problem experience at financial field. The results are followings. Firstly, consumers want to get exact and important information to decide purchase or not and comparative information in technical information area. Secondly, age is the influence variable to experience more problems in technical information section. Thirdly, consumer's subjective financial competency is major influence factor to reduce problem experience.

The present study examined the intensity of affective forecasting and the size of affective forecasting errors of people who experienced social exclusion or those high in need to belong. In Particular, a series of studies was designed to explore the moderating role of the types of future events (i.e. social vs. non-social events) in the relationship between social exclusion, the need to belong and affective forecasting. Results indicated that participants who experienced social exclusion or be high in need to belong showed significantly extreme affective ratings on the future social events compared to the future non-social events. Additional results suggested that more social exclusion experiences or higher needs to belong did not affect to the affective ratings on the experienced social events, indicating greater affective forecasting errors of socially excluded people or people with higher need to belong. The implications and limitations of the results were also discussed.

공간 지각력의 개발 ${\cdot}$ 육성은 수학교육의 중요한 목표들 중의 하나이지만, 중등학교 수학 교과서를 분석해 보면, 공간 도형에 대한 조작적 활동의 경험은 매우 빈약하다. 특히, 중학교에서는 1학년에서 공간도형의 계량적 측면에 중심을 두고 취급하고 있지만, 이를 통해 수학교육에서 추구하는 교육목표를 달성하기는 어렵다. 본 연구에서는 중학교 학생들이 공간 도형에 대해 다각적인 측면에서 분석적이고 조작적 활동을 경험하며, 이를 통해 공간 도형에 대한 상상력, 그리고 공간 도형에서의 추론 활동 경험을 제공할 수 있는 학습 자료를 개발하여 제시할 것이다.

Among the currently available binder specifications, Superpave Performance Grade asphalt specification is regarded as a superior specification on its theoretical background as well as pavement performance relationship. Many difficulties are expected; however, for Superpave implementation in Korea because of heavy burden of equipment cost as well as lack of trained personnel in asphalt industry, which may too much barrier to overcome in Korean situation. As an effort to improve qualify of asphalt binder, recently, people discuss about a possibility of constituting a performance-based asphalt specification using rather easy-to-measure asphalt properties. The objective of this paper is to determine the possibility of constituting a performance-based asphalt specification using an empirical asphalt properties, such as penetration ring and ball softening point rather than using fundamental properties of asphalt. Nine straight asphalts, that covers entire straight asphalt from all Korean refineries, and eighteen modified asphalts that were modified from two modifiers were included in the study. An analysis was made through a comparison between empirical properties and Superpave PG criteria. This study concluded that it may possible to constitute a pseudo-Superpave-like specification using an empirical asphalt properties as a specification criteria. Therefore, more systematic research is needed to constitute the asphalt specification.

This study is a study on the consumer reaction to the augmented reality advertisement which is a recent issue. this study was conducted based on the necessity of marketing advertisement technique suitable for the 4th industrial revolution era. First, we present the types of augmented reality ads based on previous studies, and examined the effects of enjoyment and formation of brand attitudes on brand attachment on products or services based on the perceived value of consumers for these types of ads. This study is briefly summarized as follows. Hypothesis (H1) empirical value had a positive effect on pleasure, and hypothesis H2) empirical value also had a positive effect on brand attitude. Hypothesis (H3) symbolic value had a positive effect on pleasure and hypothesis (H4) symbolic value had positive influence on brand attitude. Hypothesis (H5) Practical value has a positive effect on pleasure. Hypothesis (H7) Pleasure affects positively (+) influence on brand attitude. Hypothesis (H8, H9) enjoyment affects affection and brand attitude affects affection positively. Hypothesis (H6) Practical value did not affect brand attitude positively. It can be seen that the augmented reality advertisement communicates with consumers through experience or symbolic side rather than perceive practical value by consumer. The implication of this study is that the augmented reality advertisement is highly interactive with consumers and can induce consumer participation. This means that consumers are more aware of empirical and symbolic values rather than experiencing practical value through augmented reality advertising.

The current study examines the association between multiple losses and depressive symptoms and the role of social support in multiple losses. Using a prospective designed dataset(Changing Lives of Older Couples), this study found a significant difference on the depressive symptom levels between multiple losses and single loss. In addition, there was a significant buffering effect of social support in bereavement, as oppose to previous literature that social support does not buffer the initial bereavement reaction in comparisons between the bereaved with multiple losses and the bereaved with a single loss. The author discusses the importance of monitoring elderly people with multiple losses and availability of social support before and after the loss.

소프트웨어 기술의 생명주기가 점점 짧아지고 복잡해짐에 따라 그 기술을 이해하기가 힘들어 진다. 객체지향 기술채택을 더욱 잘 이해하는 것이 이 논문의 연구동기이다. 객체지향 기술이 전통적인 소프트웨어 프로세스 기술에 대한 새로운 패러다임이기 때문에 프로세스 중심의 구조지향 기술과 같은 기존의 소프트웨어 엔지니어링의 경험에 영향을 받을 수 있다. 본 연구의 목적은 이전의 구조지향 기술의 경험과 기술변화에 대한 개인적인 인식이 미국 기업체에서 객체지향 기술채택에 어떻게 영향을 미치는지를 실제로 조사하는데 있다. 2 X 2 유사 실험계획법이 사용되었다. 구조지향 방법을 사용한 경험과 새로운 기술에 대한 개인적 혁신정도(Personal Innovativeness)가 독립변수로, 객체지향 방법에 대한 사용편이성(Ease of Use)과 유용성(Usefulness)이 종속변수로 선정되었다. 데이터는 구조지향 방법과 객체지향 방법을 모두 사용한 경험이 있는 자료처리 및 관리협회(DPMA: Data Processing and Management Association)에 소속된 정보 시스템 전문가로부터 수집되었다. 연구결과는 구조지향 방법을 사용한 경험은 객체지향 방법의 사용편이성과 유용성에 영향을 주지만 개인적 혁신성은 영향을 주지 않는 것으로 나타났다. 과거의 구조지향 방법을 많이 사용하면 할수록 객체지향 방법의 사용편이성 값이 낮게 나타나기 때문에 이전 문헌에서 제시된 구조지향 방법의 객체지향 방법에 대한 지식간섭(Knowledge Interference) 현상이 있음을 실증적으로 보여주었다 마지막에는 본 연구의 한계점과 향후 연구에서 지식간섭을 줄일 수 있는 방안을 제시하였다.

댐은 하천의 흐름을 막아 그 저수를 생활 및 공업용수, 농업용수, 발전, 홍수조절, 특정용도로 이용하기 위한 구조물을 일컫는다. 여러 가지 용도로 만든 댐의 저수지에는 상류에서 들어오는 유사가 저수지 바닥에 가라앉아 쌓이게 되는데 이를 저수지 퇴사(reservoir sedimentation)라 하며, 이는 저수지 유효 용량을 감소시키고 홍수시 유입 하천의 홍수위를 상승 및 저수지 수질을 악화시키는 등의 문제를 일으킨다. 저수지를 관리함에 있어 저수지로 유입되어 바닥에 가라앉는 퇴사량을 분석하고 저수용량과 수면적의 감소율을 예측하는 것은 효율적인 저수지 장기운영에서 매우 중요한 사항이다. 본 연구에서 향후 저수지로 유입되는 일유출량의 예측을 위해 과거 1987~2011년(25년)의 충주 댐 일유입량($m^3/s$) 자료를 단순반복시켜 향후 50년 동안의 일유량($m^3/s$)을 산정하였고, 일단위 모의가 가능한 유역단위의 분포형 장기 강우-유출모형인 SWAT를 이용하여 산정된 일유량($m^3/s$) 자료를 비교 평가하여 모형의 검증을 실시하였다. 유량-유사량 관계곡선을 이용하여 분석 대상 기간 동안의 총유사량을 구할 수 있으며, 한강유역조사(2002)에서 유도한 충주댐 상류 정선지점의 유량-유사량 관계식으로부터 향후 50년의 일유량($m^3/s$) 자료를 이용하여 총유사량를 산정하였다. 또한, 경험적 면적감소법을 이용하여 임의의 기간에 대한 실측치와 모의치 각각에 대한 퇴사분포 및 퇴사량을 산정 및 평가하였다. 이를 통해 효율적인 용수관리를 위한 저수지 퇴사관리 방안의 시기별 도출이 가능하였다.

The purpose of this study is to investigate the difference of grandchild care experience and psychological health between grandfathers and grandmothers, and the effects of grandchild care experience on the psychological health of them. The objects of this study were 371 grandparents who were living in Seoul and Gyeonggi provinces and caring for children aged 3~5. The results of this study were as follows: First, grandfathers performed more basic needs fulfilling, active parent, and educational role and felt more psychological well-being and generativity. Second, both grandfathers and grandmothers had higher generativity as they carried out more social emotional support and educational roles. For grandmother, the more the role of fulfilling the basic desire and social emotional support, the higher the psychological well-being. For grandfather, however, the four care roles did not affect the psychological well-being.
