농촌인구의 급격한 감소와 고령화 속에서 농촌의 지속가능성을 위한 방안으로 귀농·귀촌의 확대가 부각되고 있다. 본 연구는 귀농·귀촌인의 생활만족도 결정요인을 분석함으로써 도시민의 농촌 이주와 성공적인 정착을 촉진하기 위한 정책적 시사점을 제공하고자 한다. 본 연구는 특히 귀농·귀촌의 주요 동기가 소득이나 농촌의 자연환경이라는 점에서, 생활만족도를 자연환경만족도와 소득만족도로 구분하여 비교 분석하는 데 목적이 있다. 분석에는 순서형 로짓모형과 일반화 로짓모형을 사용하였고, 분석자료는 2016년 「귀농귀촌실태조사」 원자료이다. 분석결과, 귀농·귀촌인의 자연환경만족도는 상당히 높으나 소득만족도는 보통 수준에 미치지 못하였다. 귀농·귀촌의 이유가 자연환경이거나, 귀농·귀촌 시 가족의 지지가 있었거나, 귀농·귀촌 이후 주변 이웃들과 좋은 관계를 유지하거나, 지자체로부터 귀농·귀촌 지원을 받은 경우, 귀농·귀촌인의 소득만족도와 자연환경만족도가 모두 높았다. 이러한 공통적인 요인 이외에 귀농·귀촌인의 소득만족도와 자연환경만족도에 영향을 미치는 요인은 뚜렷한 차이를 보였다. 소득만족도는 현재 가구소득이나 귀농·귀촌 전·후 소득 변화와 같은 경제적 요인에 의해 영향을 받으나, 자연환경만족도는 귀농·귀촌 시 배우자의 동행 여부나 지역사회 참여와 같은 사회적 요인에 의해 주로 영향을 받는 것으로 나타났다.

YouTube exhibits a hybrid personality, incorporating traits of both over-the-top (OTT) and personal broadcasting platforms. However, limited research has investigated these hybrid characteristics, particularly in the context of paid YouTube channel memberships. Therefore, building upon consumption value theory and prior literature, this study examines the influence of consumption value factors associated with paid YouTube channel memberships on usage satisfaction and continuance intention. Specifically, the study identifies four perceived consumption value factors (functional, social, emotional, and epistemic values) within the paid YouTube channel membership context and assesses their impact on usage satisfaction and continuance intention. Additionally, the study explores the moderating role of conditional value (the experience of watching live streams on paid YouTube channels) in these relationships. Data was collected via an online survey from Korean adults who subscribed to multiple paid YouTube channel memberships, resulting in 274 responses. The proposed hypotheses were tested using structural equation modeling (SEM). The SEM results indicate that all four consumption value factors significantly influence usage satisfaction, with usage satisfaction in turn positively affecting continuance intention. Furthermore, the study reveals that conditional value moderates the relationships between functional/emotional values and usage satisfaction, as well as between usage satisfaction and continuance intention. This study is the first to focus on YouTube channel paid memberships, which encompass characteristics from both OTT and personal broadcasting platforms. It is anticipated that this research will offer insights to personal broadcasters and stakeholders regarding the motivational factors that impact user satisfaction and encourage subscriptions to channel memberships.

Various tools and studies improving quality of gamification systems have been suggested. Among those tools and studies, Butler suggested the gamification framework, which shows the preference of different game mechanics, applying particular motivational and behavioral tendencies in the Myers-Briggs Type Indicator(MBTI). The purpose of this paper is to validate if the preference of different game mechanics by MBTI personality types proposed by Butler would be existing. This study pointed out the problem of suggested gamification framework from butler through literature survey. Also, this study conducted statistical analyzation and survey to prove correlation between MBTI personality types and game mechanics. Through an experiment and analysis, this study proved that there is no correlation between MBTI personality types and preference of different game mechanics. The designer of gamification systems should consider that it is not effective to apply differential game mechanics by MBTI personality types. If need to design a gamification system, designer must consider game mechanics's characteristics in applied environmental condition.

This study examined the effects of ego-resilience, critical thinking disposition, and self leadership on the career decision-making self-efficacy among nursing students. Undergraduate nursing students (N=341) were sampled randomly from nursing departments in two cities. Data collection was conducted from May 11 to June 5, 2015. The participants completed a questionnaire assessing the ego-resilience, critical thinking disposition, self leadership, and career decision-making self-efficacy. The data were analyzed with descriptive statistics, t-tests, ANOVAs, Pearson's correlations, and multiple regression. Career decision-making self-efficacy was varied by application motivation, satisfaction with one's major, personality traits, and interpersonal relationship; Self leadership was the most influential factor predicting the career decision-making self-efficacy, followed by critical thinking disposition, and satisfaction with one's major and personality traits. Therefore, these results highlight the need to devise an appropriate program to improve self-leadership and critical thinking, which will contribute to the career-related behaviors of nursing students.

The purpose of this study was to investigate the differences of influence between luxury brand value and preferences according to consumers' regulatory focus. For data collection, research questionnaires were responded by females consumers living in Pusan and Ulsan. The collected data were analyzed according to the frequency-factor analysis using SPSS 14.0 for windows Package, the factor analysis using Varimax, reliability analysis, T-test, multi-regression analysis, and chow-test. The results were as follows: First, Based on an independent samples t-test, It was found that prevention-oriented respondents were significantly more qualify value and economic value than promotion-oriented respondents, promotion-oriented respondents were significantly more aesthetic value than prevention-oriented respondents. Second, concerning the worth of luxury brands that aesthetic value, qualify value, economic value, conspicuous value, and emotional value significantly affected the consumers' preference about luxury brand. On the other hand, only social value of the luxury brand did not have a significant effect on the consumers' preference about luxury brand. Second, the study was to investigate whether the luxury brand value has an effect on the brand preference depending on the consumer's regulatory focus. The results showed that there were different perceived values of luxury brand preference between the promotion-focused and the prevention-focused consumers. The promotion focus group had the effect on conspicuous value and emotional value, while the prevention focus group had the effect on quality value and economic value for luxury brand preference.

본 논문에서는 유한버퍼의(finite-buffered) 동기화된(synchronous) 큐잉모델(queueing model)을 이용하여 명령어들간의 병렬성, 분기명령의 빈도수, 분기예측(branch prediction)의 정확도, 캐쉬미스 등의 파라미터들을 고려하여 프로세서의 명령어 실행율을 예측하며 캐쉬의 성능과 파이프라인 성능간의 관계를 분석할 수 있는 새로운 해석적 모델을 제안하였다. 해석적 모델은 모델의 타당성을 검증하기 위해서 시뮬레이션을 수행하여 얻은 결과와 비교하였다. 해석적 모델과 시뮬레이션을 비교한 결과 대부분 10% 오차 내에서 일치하였다. 본 연구를 통하여 얻은 해석적 모델을 사용하면 시뮬레이션에서는 드러나지 않는 성능제약의 원인에 대한 명확한 규명이 가능하기 때문에 성능향상을 위한 설계자료를 얻을 수 있으며, 시스템 성능 밸런스를 위한 캐쉬와 비순차이슈 파이프라인 성능간의 관계에 대한 정확한 분석이 가능하다.Abstract This research presents a novel analytic model to predict the instruction execution rate of superscalar processors using the queuing model with finite-buffer size and synchronous operation mode. The proposed model is also able to analyze the performance relationship between cache and pipeline. The proposed model takes into account various kinds of architectural parameters such as instruction-level parallelism, branch probability, the accuracy of branch prediction, cache miss, and etc.. To prove the correctness of the model, we performed extensive simulations and compared the results with the analytic model. Simulation results showed that the proposed model can estimate the average execution rate accurately within 10% error compared to simulation results. The proposed model can explain the causes of performance bottleneck which cannot be uncovered by the simulation method only. The model is also able to show the effect of the cache miss on the performance of out-of-order issue superscalar processors, which can provide an valuable information in designing a balanced system.

우리나라의 하천환경은 1990년대 이전의 산업화와 인구증가를 수반한 고도성장기를 거치면서 이수성 및 치수성만을 강조하며 개수되고 관리되었다. 그 결과 하천은 획일적인 단면과 저수로 및 제방이 콘크리트화되면서 하천의 자정능력은 감소되었고, 하천을 중심으로 생활하는 동물들의 서식처 기능을 상실해 하천생태계가 위협받고 있다. 하천공사에 자연형 하천공법이 도입되기 시작하여 자연형 하천공사가 이루어지고 있지만 생태환경의 관점보다는 조경 및 경관적, 그리고 위락적인 관점에서 공원화에 주안점을 두고 있어 하천의 생태적 특성의 반영이 부족하다는 평가를 듣고 있는 실정이다. 따라서 본 연구에서는 향후의 하천공법이 자연적 기능들 중 생물서식처 기능을 보다 깊이 다루어야 한다는 필요성을 고려하여, 먹이사슬의 최상위에 있을 뿐만 아니라 하천환경의 건강도를 판단할 수 있는 수환경의 지표종이라 불리는 수달(Lutra lutra)을 대상으로 배설물에 의한 출현빈도와 하천환경 요인들에 대한 상관관계를 분석하여 수달 서식지 복원을 위한 하천정비의 기초자료를 제공하는 데 그 목적이 있다. 이를 위해 현재 수달이 서식하고 있는 섬진강 지류인 서시천을 연구 대상지점으로 하여 5개 구간을 선정하였으며, 각 구간에 대한 계절별 수달의 배설물 분포를 조사하여 출현빈도를 나타내었다. 또한 먹이, 지형, 식생, 기상인자를 포함한 하천환경 요인들에 대한 자료를 각 계절별로 구축하였으며, 이를 수달의 출현빈도와의 상관관계를 조사하는데 활용하였다. 본 연구의 결과는 환경 기술적으로는 멸종위기종의 복원, 사회경제적으로는 하천정비사업의 방향제시 등의 기대효과를 가져올 수 있으리라 생각되며 분석된 인자들은 수달 서식지를 위한 하천정비의 기초자료에 유용할 것으로 보인다.따른 유량측정망을 구축하는 것이다.의 의사결정 지원 도구가 될 것이다. 따라서, 본 연구에서는 도시유역의 물순환 해석을 위한 일련의 과정, 즉 자료의 조사 및 취득에서부터 물순환 해석 모형을 이용한 정량적 현황파악, 물순환 개선 기법 및 평가를 수행함에 있어 주요 착안점 및 실무에서의 기술적 가이드를 제공하고자 하였으며, 보다 세밀한 도시유역의 물순환 해석을 위하여 우리나라와 일본에서 적용이 활발한 물리적 기반의 분포형 모형(WEP, SHER, SWMM)의 적용사례를 통하여 국내 도시하천의 물순환 해석에 활용함에 있어서의 실질적인 적용절차 등을 제시하고자 하였다. 한다.호강유역의 급격한 수질개선을 알 수 있다.世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와 동년대에 동일한 목적으로 찬술되었음을 알 수 있다. $\ulcorner$경상도실록지리지$\lrcorner$(慶尙道實錄地理志)에는 $\ulcorner$세종실록$\lrcorner$(世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와의 비교를 해보면 상 중 하품의 통합 9개소가 삭제되어 있고, $\ulcorner$동국여지승람$\lrcorner$(東國與地勝覽) 에서는 자기소와 도기소의 위치가 완전히 삭제되어 있다. 이러한 현상은 첫째, 15세기 중엽 경제적 태평과 함께 백자의 수요 생산이 증가하자 군신의 변별(辨別)과 사치를 이유로 강력하게 규제하여 백자의 확대와 발전에 걸림돌이 되었다. 둘째, 동기(銅器)의 대체품으로 자기를 만들어 충당해야할 강제성 당
