  • 라이브커머스 시장의 성장은 스마트폰만 있으면 언제, 어디서나, 편리하고 간단하게 라이브커머스를 시작할 수 있다. 스마트폰 서비스 이용은 지속적인 커뮤니케이션을 제공하며, 심리적 애착을 느끼면서 이용하게 되고, 더 나아가 심리적 애착과 소비자 자신과의 자아일치, 자아정체성까지 연결된다. 본 연구는 라이브커머스를 이용하는 소비자의 동기와 지각에 초점을 두고 살펴보고자 한다. 즉, 소비자의 개인적, 심리적 특성으로 조절초점성향과 자아효능감(self-efficacy)의 조절효과를 통해 서비스애착과의 관계를 살펴보려 한다. 다시 말해, 소비자의 동기와 목표에 따라 소비자의 행동 방향을 결정하게 되는 조절초점(regulatory focus)성향이 라이브커머스의 서비스애착에 영향을 미치고. 주어진 상황이나 과업에서 원하는 결과를 위해 스스로 계획하고 실행하여 목표를 달성할 수 있다는 개인적인 자신감 및 확신과 신념인 자아효능감(self-efficacy)이 이러한 관계를 조절할 것으로 본다. 분석결과, 예방초점을 높게 지각하는 소비자들은 부정적인 결과를 회피하고, 안전과 의무를 추구하는 경향이 강할수록, 개인적인 자신감과 신념인 자아효능감이 상쇄시켜 라이브커머스의 서비스에 대한 애착을 더 강하게 형성시켰다. 라이브커머스 서비스 이용 시, 정보획득에 대해 유익하다고 지각할수록, 자신의 신념인 자아효능감이 높아지므로 안전추구성향과 부정적 결과를 회피하려는 예방초점성향의 소비자들에게 인지적 경험뿐 아니라 감정적 경험인 서비스애착이 강하게 형성되는 것이다. 본 연구를 통해 라이브커머스의 서비스 이용에 대한 소비자의 심리적 행동을 이해하고, 이를 기반으로 라이브커머스에 진입하려는 기업 및 소상공인들에게 운영전략 및 관리에 도움이 되리라 본다.

  • Automatic topic essay generation (TEG) is a controllable text generation task that aims to generate informative, diverse, and topic-consistent essays based on multiple topics. To make the generated essays of high quality, a reasonable method should consider both diversity and topic-consistency. Another essential issue is the intrinsic link of the topics, which contributes to making the essays closely surround the semantics of provided topics. However, it remains challenging for TEG to fill the semantic gap between source topic words and target output, and a more powerful model is needed to capture the semantics of given topics. To this end, we propose a pretraining-based contextual self-attention (PC-SAN) model that is built upon the seq2seq framework. For the encoder of our model, we employ a dynamic weight sum of layers from BERT to fully utilize the semantics of topics, which is of great help to fill the gap and improve the quality of the generated essays. In the decoding phase, we also transform the target-side contextual history information into the query layers to alleviate the lack of context in typical self-attention networks (SANs). Experimental results on large-scale paragraph-level Chinese corpora verify that our model is capable of generating diverse, topic-consistent text and essentially makes improvements as compare to strong baselines. Furthermore, extensive analysis validates the effectiveness of contextual embeddings from BERT and contextual history information in SANs.

  • Objective : The Hoarding Rating Scale-Self-Report (HRS-SR) is a five-item scale that simply assesses the hoarding symptoms. We evaluated the factor structure, reliability, and validity of the Korean version of the HRS-SR (HRS-SR-K). Methods : A total of 144 individuals completed the self-administered questionnaires including HRS-SR-K, Obsessive-Compulsive Inventory-Revised-Korean version (OCI-R-K), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Psychometric properties of the HRS-SR-K were analyzed. Results : The Cronbach's α value for internal consistency of the HRS-SR-K was excellent (Cronbach's α=0.84). The construct validity was analyzed on the basis of principal component analysis and one-factor structure of the original scale was maintained. The HRS-SR-K total score and each item scores were more strongly correlated with the hoarding subscale score in OCI-R-K (convergent validity, r=0.71, p<0.01) than the corresponding scores of nonspecific depression or anxiety measures (discriminant validity). Conclusion : The HRS-SR-K is a simple and reliable self-report scale for examining the severity of hoarding symptoms.

  • Art works reflect the spirit and aesthetic information of the times. More specially clothing shown in paintings indicates the phases of the times and contains the aesthetic values of the era. The purpose of this study is to examine the characteristics of German Romantic Era on male and female clothing style represented in Caspar David Friedrich's paintings. The study aims to highlight the following: First, German romanticism ironically gives conceptual importance but high value to freedom of inner self and imaginative sensitivity of human beings. Second, the paintings of Friedrich show the consistency with nature through human beings' inner self and transcendency ultimately expressing religious ideals paradoxically. Third, the characteristics of male and female clothing style shown in Friedrich's paintings are considered religious, contemplative, paradoxical, transcendental, conceptual, political, grass-roots oriented, and female liberating. Female clothing reflects simple empire-style, while male clothing shows romantic style of people's leaders, reflecting the political features in those days.

  • Purpose: The purpose of this study was to develop elderly meaning in life scale with high validity and reliability. Method: The process of development of this scale were as follows. A conceptual framework composed of 4 phases of meaning in life of elderly was identified based on the literature review and interviews with elderlies and discussion with experts in meaning in life. Total 62 items, 4-points scale were developed. Through reliability testing, factor analysis, 40 preliminary items were selected. By means of internal consistency of 40 items, 2 items whose inner-items correlation coefficient was below .30 were deleted. Through factor analysis 1 item whose factor loading was below .30 was deleted. Finally 37 items were remained. To verify 37 items, factor analysis, reliability testing, LISEREL were done. Data were collected from 320 elderly subjects in Busan-KyungNam and Jeonla Province from May to June in 2002. SPSS WIN. 10.0 Program was used. Result: The result of factor analysis of 37 items, 8 factors were extracted. These factors were labeled as ‘self- awareness and self-acceptance’, ‘contentedness with life’, ‘purpose in life’, ‘love in family’, ‘role awareness’, ‘futuristic aspiration’, ‘commitment’, and ‘experience of love’. These factors included 4 phases of the meaning in life. Cronbach's Alpha of 37 items was .908 and correlation coefficient of PIL was .75. Conclusion: The researchers recommend the follows: The explorative study on the variables related to meaning in life are needed for criterion validity of this scale. The studies on meaning in life of different age groups, subjects are needed for reverification.

  • Purpose: The purpose of this study was to describe the functional (mobility, self-care, social ability) and health-related quality of life in children with cerebral palsy (CP). Methods: A cross- sectional survey of 202 children with CP, mean age $5.91{\pm}1.57$ years, was carried out using the Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Pediatric Evaluation of Disability Inventory (PEDI), and Child Health Questionnaire (CHQ). Results: The functional assessment of children with CP showed that a more severe GMFCS level was associated with lower functional abilities (p<0.05). The health-related quality of life assessment showed that psychosocial well-being was less impaired than physical well-being. The internal consistency of the three instruments was satisfactory (cronbach's ${\alpha}$>0.80). The three different scales were correlated from moderate to strong (r=0.44 to 0.92). It was also found that mobility, tone distribution, and the parents' education level exerted a significant effect on the quality of life of children with CP (p<0.05). Conclusion: These findings suggest that children with CP have reduced function and quality of life and these are influenced by various factors. However, planning and application of various task-oriented functional interventions to childhood CP may be useful.

  • Purpose: This study aims to test the validity and criteria-related reliability of the Korean version of the Copenhagen Psyco-social Questionnaire version II (COPSOQ-K) assessing the psychosocial working environment. Methods: The COPSOQ-K was developed through forward-backward translation techniques, and revision based on feedback from focus groups. Survey data were collected from 311 office workers who worked in one workplace. An internal consistency reliability was estimated by Cronbach's ${\alpha}$. The impacts of the COPSOQ-K scales on job satisfaction, self-rated health, stress, sleeping troubles, burnout, and sickness absence were analyzed with multiple regression model or multiple logistic regression model, adjusted age and gender using SAS version 9.3. The Pearson correlation coefficients between the COPSOQ-K scales and Korean job stress and its subdomain were identified. Results: Cronbach's ${\alpha}$ of COPSOQ-K scales was adequate or good (0.66~0.87). The major COPSOQ-K scales predict job satisfaction, self-rated health, stress, sleeping troubles burnout, and sickness absence. The major COPSOQ-K scales were correlated with Korean job stress and its subdomain. Conclusion: The COPSOQ-K scales have satisfactory reliability and criteria-related validity. The COPSOQ-K scales will be useful for the future studies and practices associated with psychosocial working environment.
