Objective: This study aimed to explore the readability and comprehensibility of the drug information on a patient leaflet for the senior by employing performance-based user-testing. Methods: We included 36 elderly (65 years old or older) as the senior group (intervention group) and 36 adults (40~59 years old) as the adult group (control). We developed a questionnaire to test if participants could access to drug information. After completing a questionnaire, the participant was interviewed about their understanding over the patient leaflet. We performed t-test, ${\chi}^2$-test or Fisher's exact test to examine differences between two groups in primary outcomes. Results: The senior were less likely able to find information (78%) than the adult (91%); they were much less likely able to understand information (42%) than the adult (69%). While we found differences between the ability of finding and understanding drug information in both groups, the senior group had greater difficulties in understanding all kinds of drug information. They had significant difficulties to remember information after reading the patient leaflet and frequently failed to find proper information even though they were allowed to access freely to the leaflet during interviewing. Conclusion: To secure safe and effective use of drugs for the senior, it is necessary to develop drug leaflets for the senior.

Objective: Written information could be helpful for senior population to adhere to complex medication therapies, but must be well prepared and empirically assessed to achieve such end. We purposed to develop a drug information leaflet for senior citizens by applying 'performance-based user-testing.' Methods: We employed a user-testing, a mixed method to figure difficulties out with patients' leaflets from the user perspective. The cycle made of test and revision can be repeated as necessary. We recruited senior citizens with age of 65 or above who were taking antihypertensive medications at the point of participating and excluded the elderly who suffered illiteracy. We firstly rectified a drug information leaflet of antihypertensive medications for the general public distributed by the Korean authority based on focus group interviews (9 participants). The revised leaflets were tested four times with 8~12 participants in each round (40 seniors in total). We targeted to develop a leaflet which more than 80% of participants understood 10 key information. Main outcomes measures were to be able to find information and be able to understand information. This study was approved by the Yeungnam University Research Ethics Committee. Results: Focus group interviews identified difficulties with small font of words, professional language, long information, and a poor structure. The leaflet was revised and in the first round questionnaire found problems with 4/10 information points; interviews disclosed all but one (normal blood pressure range) were ill-understood. The second round questionnaire and interview found fewer problems but the comprehensiveness of participants was still poor in several points. For the third and fourth rounds we revised the leaflets in the individual-targeted manner. Finally, the fourth round showed all key information found and understood by at least 80% of participants except one question about drug name. Conclusion: The drug leaflets need to be developed in a personalized mode for the seniors. There was a limit for Korean seniors to understand nonproprietary name of their drugs because they used to producers' trade names which the Korean health system predominantly works with.

본 연구는 우리나라 청소년들 중 음주, 흡연, 본드흡입 등을 위주로 한 약물사용 청소년들에게 특징적으로 나타나는 변인들이 무엇인지를 밝히고, 이러한 변인들과 청소년의 약물사용과의 관계는 어떻게 설명되어질 수 있는지를 고찰해 보고자 하였다 서울지역 고등학교 1, 2학년에 재학중인 남자 465명과 여자 433명, 총 898명을 대상으로 자종 약물의 사용여부와 학업성적, 비행경험, 약물사용 동료수, 지각된 약물의 입수용이도, 가족의 훈육도, 부모 외 일반적인 음주와 흡연에 대한 태도 및 자아개념 수준과 정신건강 수준을 조사하였다. 전체 표본을 사용하고 있는 약물의 수에 따라 남자 6집단, 여자 5집단으로 구분하여 위에 열거한 변인들이 집단에 따라 차이가 있는지를 검증하였다. 결과 우리나라 청소년들이 가장 많이 사용하는 약물은 담배와 술이었으며, 남자의 경우는 환각물질을, 여자의 경우는 진통진정제를 사용하는 이들이 상당수 있었다. 남자와 여자에게서 각 약물의 사용율을 전반적으로 차이가 있었으나, 그럼에도 불구하고 각 집단에 따른 변인들의 차이검증 결과는 크게 다르지 않았다. 일반적으로 여러종류의 약물을 사용하는 집단이 그렇지 않은 집단에 비해 학업성적이 낮고 비행경험 및 약물사용동료가 많았다. 또한 전자가 후자에 비해 비교적 낮은 정신건강수준과 자아개념수준을 나타냈다. 한편 차이를 나타냈던 여러변인들 중에서 무사용집단과 가장 많은 수의 약물을 사용하는 집단을 변별하는 두드러진 변인은 일반적인 적대감과 비행경험인 것으로 판별분석 결과 나타났다. 많은 종류의 약물을 사용하는 학생일수록 일상생활의 여러 측면에서 부적응적인 양상을 나타낸다는 본 연구의 결과는 약물의 사용은 공통적인 여러변인들과 관계가 있으며 많은 약물관련변인을 지닌 사람이 더 많은 약물을 사용하게 된다는 공통위험요인이론에 부합되는 것이라고 할 수 있다.

Objective: The study purpose was to develop a drug information leaflet for the elderly and to evaluate it with performance-based user-testing. Methods: We performed a stratified randomized controlled trial. We recruited 62 elderly patients with age of 65 or above who were taking antidiabetic medications at the point of participating and excluded those who suffered illiteracy. We randomly allocated them into the intervention group with a leaflet for the elderly and the control group with a leaflet for the general public. Main outcome measures were to 'be able to find information' and to 'be able to understand information.' We measured outcome variables by employing performance-based user-testing and analyzed data to find any differences between two groups with t-tests, chi-squared tests or Fisher's exact tests accordingly. Results: More participants in the intervention group understood how to store their medications than those in the control group (intervention group 93% vs. control group 70%; p=0.02). There were no significant differences in other information items between two groups. Mostly 'being able to understand information' was lower than 'being able to find information.' The gaps between two outcome variables were about 10% in the intervention group and about 18% in the control group. The lowest understanding was observed in information relating to drug names and their potential adverse events. Conclusion: Without providing personalized drug information, it might be hard for the elderly to improve their drug knowledge even with leaflets that were developed specifically for the elderly.

This study develops an effective method for sentiment analysis of user-generated content on drug review websites, which has not been investigated extensively compared to other general domains, such as product reviews. A clause-level sentiment analysis algorithm is developed since each sentence can contain multiple clauses discussing multiple aspects of a drug. The method adopts a pure linguistic approach of computing the sentiment orientation (positive, negative, or neutral) of a clause from the prior sentiment scores assigned to words, taking into consideration the grammatical relations and semantic annotation (such as disorder terms) of words in the clause. Experiment results with 2,700 clauses show the effectiveness of the proposed approach, and it performed significantly better than the baseline approaches using a machine learning approach. Various challenging issues were identified and discussed through error analysis. The application of the proposed sentiment analysis approach will be useful not only for patients, but also for drug makers and clinicians to obtain valuable summaries of public opinion. Since sentiment analysis is domain specific, domain knowledge in drug reviews is incorporated into the sentiment analysis algorithm to provide more accurate analysis. In particular, MetaMap is used to map various health and medical terms (such as disease and drug names) to semantic types in the Unified Medical Language System (UMLS) Semantic Network.

Prediction of the relations among drug and other molecular or social entities is the main knowledge discovery pattern for the purpose of drug-related knowledge discovery. Computational approaches have combined the information from different sources and levels for drug-related knowledge discovery, which provides a sophisticated comprehension of the relationship among drugs, targets, diseases, and targeted genes, at the molecular level, or relationships among drugs, usage, side effect, safety, and user preference, at a social level. In this research, previous work from the BioNLP community and matrix or matrix decomposition was reviewed, compared, and concluded, and eventually, the BioNLP open-shared task was introduced as a promising case study representing this area.

Purpose: The purpose was to identify the risk of drug use by adolescents. Method: The participants were 933 male students in the first grade of a high school in D city. The data were collected from Aug. 5th to Oct. 30th, 2004. The instrument was the High Risk Group Adolescent Drug User Screening Test(HIRIGADUST) developed by the Korea Adolescent Society(1996). The data were analyzed using SPSS. Results: For substance use, 64.5% of the students answered that they had drunk, 40.3% that they had smoked, and 2.0% that they had tried drug use. For scores on HIRIGADUST regarding socio-demographic characteristics, there were significant differences depending on school type, personality, academic performance, economic status, and ability to talk with parents. For scores on HIRIGADUST regarding drug using-related characteristics, there were significant differences depending on drinking experience, frequency of drinking, amount of alcohol intake, smoking experience and number of cigarettes smoked. Of the students 27.2% students were in the high risk group. Conclusion: In schools, systematic and intensive assessment of drug use should be done, and if needed, a service system connected to clinics specializing in drug addiction should be established. Prevention education should be carried out continuously.

기존 약국 자동화 시스템에서는 약품 최초투입 시, 설비 운용 중에 수량 측정을 하지 않은 채 메모리 상에서만 수량 관리를 해왔다. 이로 인해 설비의 오류 시 운용 도중 이미 차감되어 버린 약품에 대한 수량 관리가 이루어지지 않았다. 수량 관리가 되지 않아 관리가 필요한 중요한 약품의 경우 심각한 문제를 야기하고 있다. 또한 설비 외부에 약품에 대한 잔량을 사용자에게 알려주는 부분이 없어 사용자는 해당 약품의 재고 소진 시 약품을 다시 채워 넣어야 했다. 약품의 재고 소진 시 설비는 운용을 멈추기 때문에 재가동까지의 시간과 해당 약품을 다시 채워 넣는 시간까지의 손해를 가진 채 운영되고 있다. 이에 본 논문에서는 약국 자동화 관리 시스템의 로봇에 변위 센서를 추가하여 약품들의 수량을 수시로 관리하는 시스템을 설계 및 구현하였다.
