This study qualitatively explored the case of users utilizing multiple accounts on one social network service to create their own multiple spaces and different personas. The purpose of the study was to understand the behavior of people who use multiple accounts to express their identity online using Carl Jung's personality theory. We used in-depth interviews and the Zaltman metaphor elicitation technique (ZMET), targeting 19 people in their 20s and 30s who use more than one personal account on Instagram. Creating a shared consensus map using the configuration concept of ZMET derived six personas in relation to Instagram accounts. The motivations for the respondents' self-presentation associated with their personas and self-presentation types shown on Instagram were analyzed in terms of persona and fashion and subdivided into five dimensions: relationship management strategic presentation, self-monitoring presentation, competence demonstration presentation, anonymous presentation, and persona-centered presentation. Each respondent's persona and self-presentation formed by the Instagram account was analyzed.

Objectives: This study aimed to analyze the status of dental care in underserved areas of Korea. Methods: This study targeted 229 cities in Korea. The analytical index was revised and supplemented with variables related to dental care, and the “oral health level” indexes were further selected to provide a total of 20 analytical indexes. All selected indexes were converted into T scores (cited by the Korea Health Promotion Institute) and subjectively weighted. Finally, the regional oral health indices and areas were derived. PASW Statistics 25.0 (SPSS Inc. Chicago, IL, USA) was used to analyze descriptive statistics. Results: Gyeongbuk Cheongsong-gun had the highest dental underserved index. The city with the highest regional oral health underserved index was Jeonnam Shinan-gun. Daegu Jung-gu had the lowest dental underserved index and regional oral health underserved index. Regional gaps existed between dental care and the regional oral health underserved index according to the city province (p<0.001). Conclusions: To continuously evaluate oral health conditions and projects centered on vulnerable areas, it is necessary to develop indicators to derive vulnerable areas for dental care and to develop effective public dental policies.

A banknote counter is a machine that automates counting the money in some agencies to treat much banknotes as well as general banking agencies. The banknote counter materialized in this paper is the machine that adds the function of banknote sorting, detecting plural banknote and detecting couterfeit banknote to an existing banknote counter. The technique of sensor signal processing are used for banknote sorting. The technique of sensor application and data processing are used for detecting couterfeit banknote. The technique of precision equipment design and microprocessor application are used for high speed count. Software improved in debugging and difficulties to link with additional hardware. It was materialized through effective control algorithm and real-time signal processing with C-language on the basis of RTOS(real-time operating system) As the results so far achieved, couterfeit banknotes made by the use of a color duplicator and a color printer, are distinguished from real banknotes through mixing an optical with a magnetic sensor. And, in case that there are some different banknotes while counting, it is prevented for them to be counted without discriminating from the same kind of banknotes in addition to the function of banknote sorting.

Background : This study was performed to evaluate the prescribing pattern of β-lactam antibiotics and the relationship between antimicrobial resistance and antimicrobial use in 5 tertiary care hospitals in Korea. Materials and Methods : Data on annual patient-days and annual consumption (defined daily dose (DDD) per 100 patient-days) of β-lactam antibiotics from 2003 to 2005 in 5 tertiary hospitals were analyzed. To determine the antimicrobial resistance in K. pneumoniae, broth microdilution test and double disk synergy were performed according to the CLSI performance standards. Spearman's correlation coeffient was used to determine the relationship between antibiotic consumption and resistance. Results : The prescription of β-lactam antibiotics in 5 tertiary hospitals markedly varied. In two hospitals, increase in consumption of β-lactam antibiotics was more than 30% during recent 3 years. The higher consumption of β-lactam antibiotics significantly correlated with the higher rate of antibiotic-resistant K. pneumoniae in 5 tertiary care hospitals. Conclusion : Continuous surveillance of antibiotic use is needed to encourage appropriate prescribing of antibiotics and to reduce antibiotic resistance. 목적 : 항생제의 오남용으로 인한 내성균의 발현 및 급속한 확산이 전세계적으로 문제시 되고 있다. 특히 병원은 항생제 내성의 중심점에 있는 것으로 여겨진다. 본 연구에서는 최근 3년간 국내 5개 3차 병원의 β-lactam계 항생제의 사용량을 조사하고, 각 병원별 항생제 사용량과 K. pneumoniae의 항생제 내성률과의 상관관계를 알아보고자 하였다. 재료 및 방법 : 국내 5개 3차 병원에서 2003년 1월부터 2005년 12월까지 병원 입원 환자를 대상으로 연도별 재원연인원수와 각 β-lactam계 항생제의 총사용량을 수집하여 DDD (defined daily dose) per 100 patient-days로 환산하여 비교하였다. 2005년 6월부터 8월까지 각 병원의 임상검체에서 동정된 K. pneumoniae를 수집하여 액체배지미량희석법으로 항생제 감수성 검사를 시행하였고 ESBL(extended-spectrum β-lactamase) 생성 여부는 double disk synergy test를 시행하였다. 항생제 사용량과 내성의 상관관계는 Spearman 상관관계 분석을 시행하였다. 결과 : 5개 병원 중 3개 병원에서는 연도별 β-lactam계 항생제 사용량이 비슷하게 유지되었으나, 2개 병원에서는 2003년에 비해 2005년에 항생제 사용량이 30% 이상 증가하였다. β-lactam계 항생제 중 제제별 비율은 각 병원마다 차이가 있었으나, 3세대 cephaosporin의 사용이 가장 많았고 2세대 ceaphlosporin, β-lactam/β-lactamase inhibitor, 1세대 cephalosporin 순이었다. 경구용 β-1actam계 항생제의 사용량(r=0.900, P<0.037)과 2세대 cephalosporin의 사용량(r=0.900, P<0.037)은 각각 K. pneumoniae의 ESBL 생성과 양의 상관관계가 있었다. Ceftazidime의 사용량은 K. pneumoniae의 ceftazidime 내성률과 양의 상관관계가 있었다(r=0.900, P<0.037). 반면 imipenem의 사용량은 piperacillin/tazobactam 내성과 음의 상관관계가 있었다(r=-0.900, P<0.037). 결론 : 최근 3개년간 항생제 사용량은 병원별로 차이가 있으나 일부 병원에서는 증가하였다. β-lactam계 항생제의 사용량은 K. pneumoniae의 항생제 내성과 상관관계가 있었다. 항생제 사용을 줄임으로써 항생제 내성을 감소시킬 수 있을 것으로 기대되며, 병원별로 항생제 사용에 대한 지속적인 감시가 필요할 것이다.
