오늘날 소비는 재화의 소유권을 획득하는 것으로 인식되었던 것에서 점차 벗어나면서 재화를 구매하여 소유하는 대신 일시적으로 접근하고 이용하기 위해 비용을 지불하는 방식으로 변하고 있다. 이렇게 소유하지 않고 사용하는 경제활동을 공유경제라고 하며 이는 기본적으로 한 번 생산된 제품, 서비스 등의 자원을 많은 사람과 함께 나누어 사용하는 방식으로써 현재 전 세계에서 주목받고 있는 경제 패러다임이다. 본 연구는 공유경제 서비스의 성공요인을 이용의도로 규정하고, 유용성, 즐거움, 위험성을 공유경제 서비스의 특성으로 제시하여 이러한 특성이 소비자의 태도와 신뢰에 미치는 영향과 태도와 신뢰가 공유경제서비스 이용의도에 미치는 영향을 연구하고자 하였다. 이들 변수를 기초로 하여 8개의 연구 가설이 설정되었다. 자료는 인터넷 설문을 통해 수집하였다. 표본 크기는 250개이고, SPSS와 AMOS를 이용하여 통계분석을 하였다. 분석 결과 유용성은 태도에, 즐거움은 태도와 신뢰에, 위험성은 신뢰에 유의한 영향을 주고, 태도와 신뢰는 이용의도에 의미 있는 영향을 미치는 것으로 나타났다. 그러나 유용성은 신뢰에는 영향을 미치지 않고, 위험성은 태도에는 영향을 미치지 않는 것으로 확인하였다. Economy is transforming from the ownership of goods and services to the use or sharing of ideas, goods and services these days. This is called as ‘sharing economy’, it has attracted as a economic paradigm a great deal of attention in recent years. The purpose of this study is to find out the influencing factors of the intention of using the sharing economy services. This study defined the success factors of the sharing economy services as the intention of using it, and presented usefulness, enjoyment, and risk as influencing factors. The attitude and trust are also the important intervening variables of using the sharing economy services. This study proposed 8 hypothesis on the relationships of these variables. The data were collected through an internet survey. The sample size is 250. The data obtained were analyzed using SPSS, AMOS for windows. The results showed that usefulness has a significant effect on attitudes, enjoyment has a significant influence on attitude and trust, risk has a significant effect on trust. However, it was confirmed that usefulness does not affect trust, and that risk does not affect attitudes.

Objectives: Guided by the family systems theory (Bowen, 1966) and the Actor-Partner Interdependence Model (APIM; Cook & Kenny, 2005), this study examined the actor-partner effects of mother-adolescent communication on the psychological well-being of mothers and their adolescent children via mother-adolescent conflict and the differences between female and male adolescents. Methods: A total of 249 dyads of mothers and their adolescent children (age 13-16) in South Korea completed questionnaires on mother-adolescent communication, mother-adolescent conflict, and psychological well-being, respectively. The data were analyzed using Pearson’s correlation, path model analysis, and multiple group analysis. Results: First, the findings showed both partial actor and partner effects of perceived mother-adolescent communication on psychological well-being through a perceived level of conflict in both male and female adolescents and mother pairs. In addition, we examined sex differences for the aforementioned indirect pathways. There were sex differences in the indirect actor effects, in that mothers’ and adolescents’ own perceived communication had differential effects on psychological well-being indirectly through perceived conflict. The indirect partner effects also differed between male and female adolescents. The results of this study are meaningful because they emphasize the bidirectionality of the relationships among these variables. Conclusion: The findings contribute to the literature by highlighting the dyadic process in which mother-adolescent communication, conflict, and psychological well-being perceived by mothers and adolescents affect themselves as well as each other. This study is meaningful because the results emphasize the relationships between these variables. In utilizing a family systems approach, this study’s findings can aid in developing parent education programs, counseling interventions, and family policies that improve individuals’ psychological well-being.

Objectives : This study aimed to identify the prescription rates and prescribing patterns of relapse prevention medications for patients with alcohol dependence in an actual clinical field. Methods : In the present retrospective chart, we reviewed 109 in-patients with alcohol dependence in 2007 and 2008 ; and also carried out comparative analysis between the treatment group, who received anticraving medications and the group without the medications, with respect to their demographic and clinical characteristics and short-term treatment outcomes after hospital treatment. Results : Anticraving medications were prescribed to 36.7% of the patients at the time of day of discharge of the index admission and amongst them only 25% continued the medica-tion for more than a month after getting discharged. There was a tendency of higher prescription rate of benzodiazepine than anticraving medication and other medications such as hypnotics were also prescribed considerably. Anticraving medication group had significantly less number of admissions and shorter total period of admissions before index admission. The group also significantly exhibited more tendencies to participate in the CBT program than those without anticraving medications. The medication group took significantly more time for re-admission after discharge. Conclusions : This is the first study to provide details on the prescribing patterns of anticraving medications in Korea. There would be a need for further prospective studies to help motivate implementation of these medications.

This study examines the effect of satisfaction with adolescent extracurricular activities on social withdrawal with a focus on the mediating effect of self-esteem and sense of community. We used data from the 3rd wave (2012) of the Korean Children and Youth Panel Survey (KCYPS) collected by the National Youth Policy Institute for path analysis. Participants were 1,139 first year middle school students who participated in adolescent extracurricular activities. First, the degree of satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem. Second, satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via a sense of community. Lastly, satisfaction with adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem and a sense of community. The research findings indicate that the level of social withdrawal is less when adolescents are satisfied with adolescent extracurricular activities and have a high level of self-esteem and sense of community. The results demonstrate that a satisfactory level of adolescent extracurricular activity would help adolescents decrease their social withdrawal by increasing the level of self-esteem and sense of community.

Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

Objectives : The aims of this study are to estimate the prevalence of polydipsia and water intoxication and to identify risk factors of polydipsia and water intoxication in psychiatric inpatient. Methods : 1,108 Psychiatric inpatients at 2 mental hospitals in Yongin city were studied from September, 2008 to January, 2009. We diagnosed 'polydipsia' using staff reports(fluid intake>3L/day) or by specific gravity of urine(SPGU<1.008) and diagnosed 'at risk for water intoxication' using normalized diurnal weight gain (NDWG>4%). We attempted to identify clinical characteristics of patients by reviewing their medical records. Results : Two hundred forty seven patients(22.3%) were polydipsic. Sixty eight patients(6.1%) were at risk for water intoxication. The factors associated with polydipsia were lithium, smoking, younger age and increased smoking amounts. The factors associated with risk for water intoxication were valproic acid and polydipsia. Conclusion : Polydipsia and water intoxication in psychiatric inpatients are not rare conditions. Therefore, clinicians' attention should be paid to these conditions.

Objectives: The study aimed to investigate the main and interaction effects of callous-unemotional traits and narcissism on Korean high schoolers’ aggression. Methods: The participants were 315 high school students (155 boys, 160 girls) in South Korea. To measure the level of high schoolers’ callous-unemotional traits, the ‘Korean Inventory of Callousunemotional traits’ was used. Narcissism and aggression were measured via the ‘Narcissistic Personality Disorder Scale’ and ‘Buss-Durkee Hostility Inventory’, respectively. The data were analyzed by means of descriptive analysis, Pearson’s correlation analysis, multiple regression analysis and hierarchical multiple regression analysis via SPSS 21.0 Results: First, there were significant correlations among high schoolers’ callous-unemotional traits, aggression, and narcissism. Second, high schoolers’ callous-unemotional traits and narcissism affected aggression partially. Specifically, ‘callousness’ and ‘egocentrism’ had positive effects on aggression while ‘unemotional’ traits had a negative effect on aggression. Third, the interaction effects of high schoolers’ callous-unemotional traits and narcissism on aggression were partially significant. Specifically, the interaction effects of ‘callousness’ and ‘egocentrism’ as well as ‘uncaring’ and ‘egocentrism’ were significant. That is, the effects of ‘callousness’ and ‘uncaring’ on aggression were greater when ‘egocentrism’ was low, compared to when it was high. Conclusion: The results indicate the need for a granular approach to understanding high schoolers’ aggression and to develop counseling programs based on the role of high schoolers’ callousunemotional traits and narcissism in aggression.

윤종서 ( Jong Seo Yoon ),조연수 ( Yeon Soo Cho ),김민성 ( Min Sung Kim ),전윤홍 ( Yoon Hong Chun ),김현희 ( Yeon Soo Cho ),김진택 ( Jin Tack Kim ),이준성 ( Joon Sung Lee ) 대한소아알레르기호흡기학회(구 대한소아알레르기 및 호흡기학회) 2010 소아알레르기 및 호흡기학회지 Vol.20 No.4

목적: 소아 굴염은 치료방법에 대해 논란이 많다. 일반적으로는 항생제를 사용하는 것이 가장 기본적인 치료로 알려져 있다. 부가적인 치료로서, 식염수로 비강을 세척하는 방법 그리고 충혈 제거제의 사용이 이루어지고 있으나, 이러한 추가적인 치료들의 효과에 대하여는 아직 명확하게 밝혀져 있지 않다. 이에 저자는 굴염의 치료에 있어서, 항생제를 기본적으로 사용하고, 이에 추가로 생리 식염수로 비강을 세척하는 방법 또는 충혈 제거제 복용, 또는 이 두 가지를 함께 추가하는 치료를 시도해서 각 치료 방법의 성과를 비교하고자 하였다. 방법: 소아 호흡기질환 클리닉에 내원한 굴염 환자를 대상으로 분석하였다. 무작위로 다음의 4가지 치료법 중 한 가지의 치료법을 적용하였다. 그룹 1은 고용량 아목시실린만 사용, 그룹 2는 고용량 아목시실린에 추가로 생리 식염수로 비강 세척을 사용, 그룹 3은 고용량 아목시실린에 추가로 충혈 제거제를 사용, 그룹 4는 고용량 아목시실린에 추가로 생리 식염수 비강 세척과 충혈 제거제를 모두 사용한 경우로 하였다. 치료에 대한 반응을 급성 및 아급성 굴염의 경우은 치료 시작 후 최소 4일 후, 만성 굴염의 경우는 치료 시작 후 최소 7일 후에 평가하였다. 결과: 4개의 치료법 간의 치료에 대한 반응을 비교했을 때, 각 그룹간에 차이가 없었다. 환자가 화농성 콧물, 코 막힘, 후비루, 굴 사진에서 특정한 소견, 그리고 아데노이드 비대증을 가지고 있는가에 따라 더 좋은 반응을 보이는 치료 방법은 없었다. 결론: 소아 굴염 환자 치료 시에 고용량 아목시실린에 추가적으로 생리 식염수 비 세척이나 충혈 제거제의 경구 사용은 환자의 증상개선에 있어서 추가적인 이득이 없었다. Purpose: The management of sinusitis in children is controversial. Antibiotic is known as the most essential management. Despite nasal irrigation and nasal decongestant have been used as adjunctive treatments of sinusitis, it is still unclear whether these are effective on sinusitis. Therefore, we used antibiotics with either nasal irrigation and an oral nasal decongestant and tried to estimate the outcome of each case. Methods: This study was conducted with sinusitis patients who visited our pediatric respiratory disease clinic. They were randomized into 4 groups: Group 1 were treated with a high dose of amoxicillin only; Group 2 were treated with nasal irrigation and a high dose of amoxicillin; Group 3 were treated with a nasal decongestant and a high dose of amoxicillin; and Group 4 were treated with nasal irrigation, a oral nasal decongestant, and a high dose of amoxicillin. Responses to treatment were estimated more than 4 days after the beginning of the therapy in acute or subacute sinusitis, and more than 7 days chronic sinusitis. Results: The responses to the treatments the 4 groups were not comparable. A favorable therapy was not found, regardless of whether a patient had suppurative rhinorrhea, nasal stuffness, typical findings of PNS plain radiograph, or adenoid hypertrophy. Conclusion: The use of nasal irrigation or a oral nasal decongestant as an additional therapy to antibiotics for the symptoms of pediatric sinusitis showed no additional effects on sinusitis.

Background: Nasal eosinophil count is known to be associated with allergen-specific IgE reaction, serum total IgE level, and blood eosinophil count in patients with allergic rhinitis. Objective: To examine the association between nasal eosinophil count and other clinical indices in children with chronic nasal symptoms. Method: The medical records were reviewed retrospectively. The smears of nasal swabs were examined under the light microscope for nasal eosinophil count. The statistical analysis was done in correlation to nasal eosinophil count and clinical indices. Result: The number of patients with a history of allergic diseases other than allergic rhinitis and positive reactions to serum allergen-specific IgE antibodies in the considerable group (52.9% and 92.0%) was significantly higher than those in the absent group (28.8% and 55.1%) (P<0.05). The number of patients with nasal symptom duration of less than 3 weeks in the absent group (31.2%) was significantly higher than that in the other groups (P<0.05). Blood eosinophil counts were significantly higher in the considerable group (491.2±264.0/mm3) than those in the absent group (310.2±293.7/mm3) (P<0.05). Conclusion: Nasal eosinophil counts significantly correlated with a history of other allergic diseases, duration of nasal symptoms, positive reactions to serum allergen- specific IgE antibodies and blood eosinophil count.

김현희 ( Hyun Hee Kim ),남지선 ( Ji Sun Nam ),조연수 ( Yeon Soo Cho ),전윤홍 ( Yoon Hong Chun ),윤종서 ( Jong Seo Yoon ),김진택 ( Jin Tack Kim ),이준성 ( Joon Sung Lee ) 대한소아알레르기호흡기학회(구 대한소아알레르기 및 호흡기학회) 2010 소아알레르기 및 호흡기학회지 Vol.20 No.4

목적: 응급실을 방문한 소아 천식 환자에게, 근거에 중심을 둔 표준 진료 지침을 적용하는 것이, 우리나라의 응급실에서 정확하게 시행될 수 있는지 알아보고 표준 진료 지침의 정확한 적용이 치료의 효과를 향상시키는지를 알아 보고자 하였다. 방법: 2009년 1월 1일부터 2009년 12월 31일 까지 천식의 급성 악화를 주소로 응급실을 방문한 소아 환자 전원에게 표준 진료 지침을 적용하였다. 응급실 진료기록을 조사하여 표준 진료 지침이 정확하게 적용되었는지를 조사하였다. 또한 정확하게 적용된 집단과 부정확하게 적용된 집단으로 나누어 치료의 효과를 비교 하였다. 결과: 연구 대상 51명의 급성 천식 악화 환아 중 표준 진료 지침이 정확하게 적용된 환자는 24명(47%)이었고, 부정확하게 적용된 환자는 27명(53%) 이었다. 부정확하게 적용된 군에서는 중등도 악화가 많았다. 부정확하게 적용된 내용으로는, 흡인성 항콜린제를 사용하지 않았거나 적게 시행한 경우가 가장 많았다. 잘못 적용된 이유로는 응급실에서 환자를 진료한 전공의의 숙지 미숙이 가장 많았다. 표준 진료 지침의 항목 중 핵심적인 치료를 부정확하게 실행한 환자에서 병실로의 입원율이 높았다. 결론: 응급실을 방문한 소아 천식 환자에 대하여, 표준 진료 지침을 적용하는 것은 치료의 효과를 향상 시켰다. 그러나, 이 지침을 정확하게 적용하기 위하여는 중등도 악화 환자에 대한 집중 관리 및 응급실에서 진료를 하는 전공의에 대한 교육의 강화가 필요하다. Purpose: This study aimed to determine whether the standard clinical pathway based on evidence is applicable to pediatric asthma patients in the emergency room, and whether it is better for treatment effectiveness. Methods: The clinical pathway was applied to children who visited our emergency room due to acute asthma between January 1 and December 31, 2009. Medical records of the emergency room were reviewed to see if the clinical pathway was correctly applied. The patients were divided into 2 groups: those who the pathway was correctly applied and those who the pathway was incorrectly applied to (group B, n=41). Results: Acute asthma exacerbation occurred in 24 children (47%) in group A, while it occurred in 27 children (53%) in group B. The majority of patients in group B had moderate asthma exacerbation. The incorrect application of the clinical pathway and no use or insufficient use of inhaled anticholinergics was most frequently noted. The most common cause for the incorrect application of the clinical pathway was its misunderstanding of residents. The hospitalization rate was higher in group B than in group A. Conclusion: The application of the clinical pathway to pediatric asthma patients in the emergency room increased treatment effectiveness. However, training for the residents and intensive care for the patient with moderate asthma exacerbation are necessary for correct application of the clinical pathway.
