The purpose of this study was to examine the abuse experience of adolescents in out-of-home care on their psychosocial adjustment and the mediating effects of self-regulation skills. A survey was conducted on the adolescents who resided in the city of Busan and received out-of-home care service. The findings of the study were as follows: First, abuse experience was found to have exerted a negative influence on self-regulation skills. Second, abuse experience was found to have exerted a negative influence on psychosocial adjustment. Third, self-regulation skills were found to have exercised a positive influence on psychosocial adjustment. Fourth, self-regulation skills were found to have had a mediating effect on the relationship between abuse experience and psychosocial adjustment. The findings of this study were of significance in that neglect and emotional abuse should be prevented to promote the psychosocial adjustment of teenagers with abuse experience who are in out-of-home care, and in that the importance of the intervention of counseling programs which could foster the self-regulation skills of adolescents was urged.

미용업의 사회적 인식이 높아짐에 따라 국내 미용서비스산업은 경영적 측면에서 체계화되고 규모면에서도 날로 확대되는 등 양적, 질적인 성장하고 있으며, 국내 업계끼리는 물론이고 글로벌화로 인하여 외국의 선진 프랜차이즈와도 경쟁하는 단계에 이르렀다. 이러한 환경적 변화 속에서 국내의 미용업계는 한 차원 높은 성장을 위한 자구적 노력이 필요한 상황이다. 그러나 국내 미용업계는 서비스 제공자 관점에서 일방적인 서비스를 제공하여 왔고 고객관점에서 가치 있는 서비스의 내용과 품질을 제대로 파악하지 못하고 있는 실정이다. 미용서비스품질을 정의하기 위한 연구들은 계속되고 있으나 미용서비스품질에 대한 명확한 개념정의는 물론이고 앞으로 국내 미용업계 성장의 축이 될 브랜드 미용실의 고유 서비스품질은 여전히 확정적이지 못한 실정이다. 따라서 본 연구에서 브랜드 미용실 고유의 서비스품질 요인들을 발견하고, 지각된 가치, 고객만족, 재이용의도 간의 인과관계를 알아보고자하며, 특히 지각된 가치의 매개적 역할과 계량적 중요성을 알아보고자 하였다. 또한 브랜드 미용서비스를 이용하는 고객들의 단골고객 신념수준에 조절효과가 있는지 알아보기 위하여 가치-고객만족, 가치-재이용의도, 고객만족-재이용의도 간의 이에 대한 조절효과를 검정하였고, 효과적인 서비스품질전략을 제시하고자 하였다.

Forest ecosystem provides variety goods and services for human being. Unlike goods, forest ecosystem services could not be easily priced by market mechanism. This uncertainty has been caused to conflict in decision-making related forest ecosystem services. Quantification of forest ecosystem services is required to understand the importance of ecosystem services and their contribution to decision-making. As a growing concern of climate change, it is necessary to quantify and calculate carbon storage and sequestration in forest. In this study, for quantifying carbon storage and sequestration, we compared scale, output, input data availability of the models and analyzed the applicability of the models to Korea. The results of this study show that most models are applicable for quantifying carbon storage and sequestration. However, relatively few models are applicable for other regulating services (air quality regulation, flood mitigation, erosion control, water quality, etc.) of forest. This study would be helpful for quantifying regulating services of forest ecosystem research.

We Investigated the Two Additional Effects Regarding the Causal Relationship between the Perceived Risks of cloud Services on the Intention to use the Abandonment Option. First, we Empirically Tested the Moderation Effect of IS Maturity on the Causal Relationship between these Two Variables. Second, we also Investigated the Mediation Effect of Cloud Service Satisfaction on the same Causal Relationship. We could find the Moderation and Mediation Effect only on the Influence of Relational Risk (Which Occurs from the Power Abuse of Cloud Service Providers) on the Intention to sue the Abandonment Option. So, we have better Understanding when and how the Abandonment Option is Attractive in Reducing the Potential Influence of the Relational Risk in using the Cloud Services.

A human in urban areas has depended on ecosystem for well-being, so it is important to evaluate urban ecosystem services which contribute significantly to human well-being. In this study we classified ecosystem functions and set indicators used for evaluating ecosystem services of urban park by Delphi method. As a result, it derived 12 items and 14 indicators of ecosystem services to evaluate them such as vegetable garden, canopy cover, biodiversity, and educational programs. Based on the derived evaluation indicators, the feasibility of the indicators was examined by applying to two urban parks, Maetan park and Seoho-Ggotme park, in Suwon City. We also suggested strategies to improve each ecosystem services based on the results of evaluation. It is significant to recognize unknown services in urban parks. The results can be used for improving urban ecosystem services consistently in response to current rapid urbanization. In the future, the city should make a master plan on ecosystem service on urban area, beyond urban park, considering both of quality and quantity.

본 연구는 TAM 모형을 기반으로 유용성과 경제성 변수에 기업의 고객 충성도를 조절변수로 하여 유무선 결합서비스(FCM)에 대한 소비자의 수용의사에 대해 연구하였다. 그 결과, 소비자들은 FCM 의 유용성과 경제성에 유의한 영향을 미치고 있으며, 기업에 대한 고객 충성도는 조절효과를 가지고 있었다. 소비자들은 현재 유선기반의 단순묶음(bundling)형태의 서비스를 주로 이용하고 있으며, 경제성(요금의 적합성)에 대한 만족도는 높지 않았다. 또한, 소비자들은 현재의 서비스와는 상관없이, 향후 FMC 활성화에 따라 통신사의 변경을 고려하고 있어 기업에 대한 신뢰보다는 제공 서비스의 품질과 효과를 우선시 하고 있음을 나타냈다. 향후 결합서비스의 중심서비스로는 이동전화를 선호하고 있었으며, 결합서비스 형태로는 인터넷과 인터넷 TV 를 결합한 서비스를 추구하고 있었다. 본 연구는 향후 통신사업자들의 바람직한 FCM 의 구성과 요금정책 전략 수립에 있어 다소나마 도움을 줄 수 있을 것으로 판단된다. 각 사업자는 유무선 결합서비스가 성공적인 비즈니스모델로 정착하기 위해 소비자들의 효용을 정확히 알고 소비자들에게 맞는 우수한 콘텐츠와 기능적 품질의 제공이 무엇보다 중요하게 될 것이다.

유비쿼터스 환경의 필수 부분인 홈 네트워크는 많은 서비스들을 가지고 생활 곳곳에 파고들고 있다. 정부의 IT839정책을 기반으로 홈 네트워크의 실용화와 구체적인 정책을 형성하기 위해 활발한 연구가 진행되고 있다. 국내와 해외의 홈 네트워크 융성 정책 비교, 고객의 홈 네트워크 서비스 별 선호도를 비롯하여 최근에는 홈 네트워크 서비스의 사용의도와 관련한 연구들까지 있었다. 본 연구는 이러한 연구들을 바탕으로 홈 네트워크 사용의도에 영향을 주는 요인들을 조사하고 이 관계에 있어서 인구통계 변수인 연령과 인터넷 사용량의 조절효과를 측정해보았다. 그리고 홈 네트워크를 자동화 서비스, 안전 서비스, 엔터테인먼트 서비스 세 집단으로 나누고 각각을 따로 분석하였다. 분석 집단은 현재 운영되고 있는 홈 네트워크 서비스를 직접 사용해 본 경험이 있는 아파트 거주자이다. 분석 결과 연령이 높을수록 홈 엔터테인먼트 서비스 사용 시 서비스의 사용용 이성과 보안성이 중요하게 작용하였다. 또한 인터넷 사용량이 많은 집단은 홈 자동화 서비스의 사용 시 해당 서비스로부터 얻을 수 있는 효용, 편익을 중요시 여겼다.

The growth of the live commerce market allows you to conveniently and simply start live commerce anytime, anywhere with a smartphone. The use of smartphone services provides continuous communication and is used while feeling psychological attachment, and it leads to psychological attachment, self-consistency with consumers themselves, and self-identity. This study focuses on the motives and perceptions of consumers using live commerce. In other words, we will examine the relationship with service attachment through the moderating effect of self-efficacy and control focus tendency as consumers' personal and psychological characteristics. In other words, the tendency of regulatory focus, which determines the direction of behavior of consumers according to their motives and goals, affects the service attachment of live commerce. We believe that self-efficacy, which is personal confidence and belief that you can plan and execute on your own for the desired outcome in a given situation or task, will control this relationship. As a result of this research, consumers who highly perceive prevention focus were more likely to avoid negative consequences and pursue safety and obligations. Their attachment to live commerce services was stronger, offsetting their confidence and self-efficacy. When using live commerce services, the more they perceive that information acquisition is beneficial, the higher their belief, and self-efficacy, so service attachment, which is an emotional experience as well as a cognitive experience, is strongly formed for consumers with a preventive focus to avoid safety-seeking and negative consequences. Through the present research results, we believe that it will be helpful in operating strategies and management for companies and small business owners who want to understand the psychological behavior of consumers in using live commerce services.

HTTP (Hypertext Transfer Protocol) Adaptive Streaming is gaining attention because it changes bitrates to adapt changing network conditions. Since HAS (HTTP Adaptive Streaming) client downloads the video data based on TCP (Transmission Control Protocol), it estimates incorrectly the available bandwidth and leads to an unnecessary video quality change in long-delay networks. In this paper, we propose a buffer-based quality control scheme in order to improve the service quality and smooth playback in the HAS. The proposed scheme estimates accurately the available bandwidth based on a modified streaming model that considers network delay. It also calculates the sustainability of the video quality to prevent an unnecessary quality change and determines the inter-request time on the basis of the buffer status. Through the simulation, we prove that our scheme improves the QoS (Quality of Service) of the HAS service and controls the video quality smoothly in long-delay networks.
