Objectives: This study examined the extent to which children’s self-esteem influenced their smartphone dependency through social withdrawal and whether this mediating path would vary depending on parents’ provision of structure. Methods: This study included data on 2,394 fourth-grade elementary school children(boys, n = 1191; M = 10 years old, SD = .09), taken from the 2018 Korean Children and Youth Panel Survey conducted by the National Youth Policy Institute. Descriptive statistical analysis and correlation analysis were conducted using SPSS 26.0. In addition, the Process Macro No. 8 model was used to examine the moderated mediating effects of social withdrawal and parental provision of structure. Results: It was found that children’s self-esteem significantly and directly influenced their smartphone dependency, and indirectly influenced smartphone dependency through social withdrawal. Parents' provision of structure significantly moderated the association between children's self-esteem and social withdrawal, and the association between children’s self-esteem and smartphone dependency. Parents’ provision of structure also moderated the mediating effect of social withdrawal in the path between children’s self-esteem and smartphone dependency. This suggests that a high level of parental structure strengthens the beneficial effects of children’s self-esteem on smartphone dependency through reduced social withdrawal. Conclusion: This study examined how children’s individual characteristics and parenting behavior interact to influence children’s smartphone dependency. The findings highlight the importance of developing and implementing parent programs to support positive parenting practices and promote children’s healthy adjustment

구혜민,허정윤,황은영 인제대학교 디자인연구소 2018 Journal of Integrated Design Research (JIDR) Vol.17 No.1

연구배경: 무선인터넷 기술을 바탕으로 한 스마트 온도조절기 산업 확대로 사용자는 스마트 환경에서 가정의 온도 조절기를 효율적으로 관리할 수 있게 되었다. 기존 스마트 온도 조절기는 단순 ‘원거리 전원 조작' 기능을 중심으로 기능과 UI가 집중되어 있다. 이러한 기능과 UI 는 변화된 사용 맥락 속에서 복합 조작에 대한 요구를 반영하고 있다고는 보기 어려운 실정이다. 연구방법: 본 연구에서는 현재 상용화된 스마트 온도조절기 서비스 중 보다 복합적인 기능을 포함한 스마트 온도 조절기를 대상으로 능동적 조작에 대한 사용자의 요구를 파악하고 정보의 제시 형태, 정보의 우선순위를 반영한 개선안을 목적으로 한다. 연구결과: 설문조사를 통해 스마트 기기 시대에도 사용자의 능동적 기기 조작 요구가 분명히 존재한다는 것과 사용자의 의사결정에 필요한 정보 중 ‘시간’, ‘비용’ 관련 정보를 가장 먼저 필요로 하는 것을 파악하였다. 이는 먼저 ‘시간’, ‘비용’ 정보를 제공해야 한다는 것을 의미한다. 결론: 설문조사를 통해 발견한 ‘정보 제시 형태’와 ‘자율 조작 단계’를 바탕으로 가정용 온도 조절기 UI 가이드라인을 도출하여 프로토타입을 제작하였다. 프로토타입 사용성 평가의 결과를 비교, 대조하여 가이드라인의 실증적인 검증을 할 수 있었다. 이를 통해 본 연구에서는 능동적인 의사 결정을 유도하는 사용자 UI 설계 요소를 제안하였다. Background: With wireless Internet technology based on wireless Internet technology, users can efficiently manage the thermostat controls. The UI of the existing smart climate controls is currently taking the configuration of the current state information in the form of information. The function and UI of the remote control panel, which provides remote manipulation of the remote control panels only, is not reflected in the functionality of the user, indicating that they reflect the diverse needs of users. Methods: This study aims to recognize the above problems, including the more complex functions of the current commercial control, including the more complex functions of the LTE service, and the purpose of the information presented to the users of the information, and the purpose of presenting the information of the information presented. Result: The survey found that the user's active device operating needs clearly exist in the era of smart devices, and the information needed for the user's decision was first identified in the context of the user's decision. This means that it should first be provided with ‘Time’ and ‘Cost’ information. Conclusion: Based on the ‘Information presentation form’ and ‘The Balanced Step,’ the prototype was produced by deriving the prototype thermostat guide guidelines. Comparison of the results of the prototype usability assessment was evaluated, demonstrating the verification of the guidelines. In this study, the study proposed a study of user UI design elements that lead to active decision-making in this study.

확장된 계획행동이론을 적용한 매춘관광 의도 연구 -성매매에 대한 인식과 사전지식의 역할을 중심으로-

구혜민,정지연 한국관광학회 2021 관광학연구 Vol.45 No.5

Using the extended theory of planned behavior, this study was to analyze the effects of ethical and social perceptions, human rights perceptions, and health perceptions related to prostitution, as prerequisite variables on the attitudes and behavioral intentions of sex tourism. Structural equation model analysis and ANCOVA were performed to test hypotheses using a total of 304 valid questionnaire responses. Results showed that ethical and social perceptions and health perceptions had a significant negative effect on attitudes toward sex tourism, whereas human rights perceptions did not. It was also found that attitude and subjective norm had a significant positive effect on behavioral intentions, but perceived behavioral control did not significantly affect sex tourism intentions. In particular, it appeared that the ethical and social perception had a significant total negative effect on the intention of sex tourism. In the moderating effect analysis, using prior knowledge of prostitution-related laws, the group with high prior knowledge level had a relatively lower influence on behavior of sex tourism attitudes than the group with low level of prior knowledge. However, ANCOVA found no significant differences between the two groups, indicating that moderating effects differ by gender. This study has academic value in that it conducts an empirical study on sex tourism, a topic that is somewhat difficult to bring out in Korea. Results of this study could contribute to establishing effective policies to reduce illegal sex tourism. 이 연구는 성매매에 대한 윤리·사회적 인식, 성매매 종사자에 대한 인권적 인식, 보건적 인식을 선행변수로 하여 매춘관광에 대한 태도와 행동 의도에 미치는 영향에 대하여 확장된 계획이론에 적용하여 분석하였다. 총 304부의 유효한 설문지 응답에 대하여 기술통계분석, 탐색적 요인 분석, 확인적 요인 분석, 구조방정식모형 분석, 및 공분산분석을 시행하였다. 성매매에 대한 윤리·사회적 인식과 보건적 인식은 매춘관광 태도에 유의한 부정적 영향을 미쳤으나, 성매매 종사자 인권에 대한 인식은 매춘관광 태도에 유의한 영향을 미치지 않았다. 매춘관광 태도와 주관적 규범은 행동 의도에 유의한 정(+)의 영향을 미쳤지만, 지각된 행동통제는 매춘관광 의도에 유의한 영향을 미치지 않았다. 특히 성매매에 대한 윤리·사회적 인식은 총 효과에서도 매춘관광 행동의도에 유의한 부(-)의 영향을 미쳤다. 성매매 관련 법률 사전지식을 조절변수로 한 조절 효과 분석에서는, 매춘관광이 불법이라는 사전지식 수준이 높은 집단이 낮은 집단보다 매춘관광 태도가 행동에 미치는 영향도가 상대적으로 낮았다. 즉, 성매매 법률 사전지식은 매춘관광에 대한 행동 의도를 낮췄다. 하지만 공분산분석에서는 사전지식이 높은 그룹과 낮은 그룹 간의 태도와 행동의도에 유의한 차이가 없었으며, 남녀 간 조절효과의 차이가 있음을 확인하였다. 이 연구는 국내에서는 다소 꺼내기 어려운 주제인 매춘관광에 대한 실증적 연구를 시행하여 유의한 결과를 도출해냈다는 점에서 학술적 가치가 있을 뿐만 아니라, 향후 매춘관광을 줄이는 관련 정책을 마련하는데도 실질적인 기여를 할 수 있다는 점에서 실무적 가치도 있다.

Purpose: Although heart failure (HF) is recognized as a leading contributor to healthcare costs and a significant economic burdenworldwide, studies of HF-related costs in South Korea are limited. This study aimed to estimate HF-related costs per Korean patient per year and per visit. Materials and Methods: This retrospective cohort study analyzed data obtained from six hospitals in South Korea. Patients with HF who experienced ≥one hospitalization or ≥two outpatient visits between January 1, 2013 and December 31, 2013 were included. Patients were followed up for 1 year [in Korean won (KRW)]. Results: Among a total of 500 patients (mean age, 66.1 years; male sex, 54.4%), the mean 1-year HF-related cost per patient was KRW 2,607,173, which included both, outpatient care (KRW 952,863) and inpatient care (KRW 1,654,309). During the post-index period, 22.2% of patients had at least one hospitalization, and their 1-year costs per patient (KRW 8,530,290) were higher than those of patients who had only visited a hospital over a 12-month period (77.8%; KRW 917,029). Among 111 hospitalized patients, the 1-year costs were 1.7-fold greater in patients (n=52) who were admitted to the hospital via the emergency department (ED) than in those (n=59) who were not (KRW 11,040,453 vs. KRW 6,317,942; p<0.001). Conclusion: The majority of healthcare costs for HF patients in South Korea was related to hospitalization, especially admissions via the ED. Appropriate treatment strategies including modification of risk factors to prevent or decrease hospitalization are needed to reduce the economic burden on HF patients.

This study analyzed the use of injectable drugs with oral-formulation alternatives in theoutpatient setting in South Korea. We conducted a retrospective cross-sectional data analysis using 2008 National Health Insurance claims data. All active ingredients were categorized into dual-formulation ingredients (DFIs) and single formulation ingredients (SFIs), and were identified by the type of healthcare service provider (HSP) and anatomical therapeutic chemical (ATC)group.14.6 %(102/701)oftotaldrugswereextracted as DFIs at about the same rate as that for drugs in the World Health Organization database (14.45 %), showing similar patternsbyATCgroup.Therateofinjectabledrugusevaried more substantially for DFIs (range 0.94–4.54 %) than for SFIs (range 0.27–1.12 %) by the type of HSP. For DFIs, the highest proportion of injectable drug use was observed in group H (all hormonal preparations, 22.74 %) and group M (anti-inflammatory and anti-rheumatic preparations, 10.23 %) among ATC groups. The proportion of injectable drug use was higher in clinics and small hospitals than in tertiary hospitals and general hospitals where patients with more severe cases tend to visit. The results imply the potentiallyinappropriateorexcessiveuseofinjectabledrugs and suggest the need to develop standard guidelines for injectable drug use and strategies to promote high-quality healthcare including education on rational prescribing.

This study specifically focused on the gender differences in longitudinal pathways among social withdrawal, peer relationships, and smartphone dependency of 9 to 13-year-old children. The first(2018, 4th grade), second(2019, 5th grade), and third(2020, 6th grade) waves of the Korean Children and Youth Panel Survey(KCYPS) 2018 were used, and data on a total of 2,199(boys, n=1,094) were taken. Multigroup analysis based on structural equation model, bootstrapping and wald test were used for analyses. First, the pathway that social withdrawal(4th) had positive effects on smartphone dependency(6th) was significant in both genders. Second, the pathway that social withdrawal(4th) had negative effects on peer relationships(5th) was also significant in both. Third, the pathway that peer relationships(5th) had negative effects on smartphone dependency(6th) was significant only in girls. Fourth, the mediating effects were significant only in girls. The study results implied the importance of internal characteristics in the elementary upper-grade periods, and suggested the necessity of a support for socially withdrawn children. Also, this study can be used as basic data for the prevention of smartphone overdependence in this age.

자기통제와 처벌확신이 관광객 일탈행동에 미치는 영향에 관한 연구: 목표지향적행동 모형을 적용하여 한국과 미국 비교

구혜민,정지연 한국마이스관광학회 2024 MICE관광연구 Vol.24 No.1

The purpose of this study is to examine the effects of self-control and certainty of punishment on deviant tourist behaviors by applying the model of a goal-oriented behavior. A total of 911 data was collected from South Korea and the United States to compare two cultures based on the Hofstede’s indulgence-seeking index. Certainty of punishment had significantly negative effects on both groups, but self-control had significant effects on the United States group only. In the group with a high indulgence-seeking index, self-control in daily life increased attitudes, desire, and intentions toward deviant behavior, while certainty of punishment suppressed the desire for deviant behavior. This study has academic and practical significance in that it confirms the antecedent variables for intention to deviant behavior and confirms the existence of differences according to cultural values.
