  • 연구목적: 인터넷 중독이란 '과도한 인터넷 사용에 의해 현실생활에 어려움을 겪게 되는 경우', '인터넷에 과도한 시간을 사용하거나 현실세계에서의 진정한 인간관계가 가상공간에서의 표면적인 관계로 대치되는 것', '인터넷 사용에 대한 자기조절 능력이 현저히 약하고 사용을 금지할 경우 심리적 혼돈과 무기력에 빠지게 되는 상태' 등으로 정의되는 새로운 형태의 중독 현상을 지칭한다. 본 연구에서는 경제적, 문화적, 지리적 여건이 다른 서울, 천안, 농촌지역 중고교 학생들을 대상으로 인터넷 중독율, 인구학적 변수들, 컴퓨터 사용성향, 불안성향, 우울, 그리고 가상공간을 통한 자기 효능감이 각 지역간에 어떠한 차이가 있는지를 알아보고자 하였다. 방법: 연구대상군은 서울, 천안, 천안근교 농촌 소재의 남녀 중고교생 1718명을 대상으로 하였으며 사회인구학적인 변인에 대한 문항들, the Spielberger State-Trait Anxiety Inventory (STAI)를 김정택이 번안한 한국판 상태-특성 불안척도, Self-Rating Depression Scale (SDS)을 이중훈이 번안한 한국판 자기평가 우울척도, 인터넷 사용 성향을 묻는 문항들, Young, K. S.의 인터넷 중독 진단 척도를 윤재희가 번안하였고 본 연구자가 청소년에 맞게 수정한 인터넷 중독척도, J. W. Henry & R. W. Stone이 개발한 computer self-efficacy and outcome expectancy scale과 Paulhus, Delroy가 개발한 Spheres-of-Control Battery Item을 송원영이 번안, 수정하여 사용한 가상공간 활용에 대한 자기효능감 및 결과기대척도로 구성된 설문지를 해당학교장의 협조를 받아 교실 내에서 학생들이 작성하는 방식으로 연구가 시행되었다. 결과: 연구결과 전체 대상군의 인터넷 중독율은 2.9%였으며 세 지역간에 인터넷 중독율에 있어서 유의한 차이는 발견되지 않았다. 전체 대상군의 경우 농촌이 서울이나 천안에 비하여 높은 불안, 우울정도를 보였고, 서울, 천안, 농촌 순으로 높은 가상공간활용에 대한 자기효능감을 보였으며 천안, 서울, 농촌 순으로 여가생활을 혼자 지내는 비율이 높았으나 중독군 만을 대상으로 하였을 때는 이러한 차이가 없었다. 전체 대상군의 경우 인터넷에 접속하는 장소에 있어서 서울, 천안, 농촌 순으로 가정이 많았으며 인터넷 접속방법에 있어서도 서울, 천안, 농촌 순으로 초고속 인터넷의 사용율이 높았으나 중독군 만을 대상으로 하였을 때는 이러한 차이가 없었다. 인터넷 중독에 대한 인식에 있어서는 전체 대상군의 경우 서울, 천안, 농촌의 순으로 인터넷에 중독되어 있다고 생각하는 비율이 높았으나 중독군 만을 대상으로 하였을 때는 이러한 차이가 없었다. 결론: 이번 연구결과를 보면 인터넷 중독율은 세 지역간에 차이가 없었으며 불안, 우울, 가상공간활용에 대한 자기효능감, 여가형태, 인터넷 접속장소, 인터넷 접속방법, 인터넷 중독에 대한 인식에 있어서 전체 대상군에서는 세 지역간에 차이가 있음에도 불구하고 중독군의 경우에는 이러한 차이가 없어 지역간 중 고교 학생들의 심리적 상태, 여가형태, 인터넷 환경, 인터넷 중독에 대한 인식은 차이가 있으나 인터넷에 중독되면 이러한 차이가 없어지고 비슷한 형태의 중독군을 형성함을 알 수 있었다.

  • In order to investigate supplement use in middle-aged and elderly outpatients suffering from age-related diseases over the last year, a cross-sectional survey was conducted from July to December 2001. The subjects were 1702 (male 731, female 971) age-related disease outpatients over age 50. Data was collected using a standardized questionnaire and in-person interviews. The prevalence of supplement use and the different categories of supplements taken by the subjects were examined using SPSS statistical package. Supplements were used by 48.9% of the subjects. The mean number of kinds of dietary supplements taken by subjects was 1.7. Chinese medicine was the most commonly used supplements in both the male and female subjects. Among the reasons for using supplements, health promotion ranked as the most common. Most of the supplement users, however, did not know or only knew roughly about the health claims of their supplements. Subjects reported the information source on supplements as family, friends or relatives followed by doctors or pharmacists. These results may provide basic information for proper supplement use among Korean middle-aged and elderly outpatients with age-related diseases.

  • Nutrient supplements are often used by athletes as ergogenic aids. This study was done to investigate the use of nutrient supplements, nutritional knowledge and nutrient intakes of athletes. Subjects of this survey consisted of 195 national team athletes. The prevalence of nutrient supplement use among all subjects was 30.3%, and the frequency of use, by decreasing order, was weight lifting, taekwondo and badminton athletes. Sport drinks were the type of nutrition supplement used most frequently and vitamin C was the second one. Major reasons for nutrient supplement use were to improve training performance and to recover from fatigue, to supplement fluid and to control weight. The average score of nutritional knowledge was $19.9\pm{2.5}$ for nutrient supplement users, and $19.8\pm{3.6}$ for nutrient supplement nonusers. Intakes of protein, calcium and niacin of the user were higher than those of the nonuser. This information provided by this study can help sport nutritionists identify nutrient supplement most often consumed by national elite athletes and can aid counselors as they guide athletes towards more healthful nutrition practices.

  • Purpose: The purpose of this study was to use cone-beam computed tomography (CBCT) images to determine the prevalence of calcifications in the temporomandibular joint (TMJ) and to evaluate any associations between the presence of such calcifications and degenerative bone alterations of the TMJ, sex, or age. Materials and Methods: In this retrospective study, 1,058 CBCT exams were analyzed, and data regarding the presence and quantity of calcifications, the affected side, any degenerative alterations of the condyle, sex, and age were collected. To evaluate associations between the presence of calcifications and sex or age, the Fisher exact test or the Spearman correlation coefficient, respectively, was used. To assess the association between the presence of calcifications and joint bone alterations, the chi-square and Fisher exact tests were used. The significance level adopted was 5% (P<0.05). Results: Twenty-eight patients (2.7%) presented with TMJ calcifications, including 23 women (82.1%) and 5 men (17.9%). Significant correlations were found between the presence of calcifications and age (P<0.05) and between the presence of calcifications and the presence of condylar alterations (P<0.05), with 73.2% of patients with bone alterations having TMJ calcifications. Conclusion: It may be concluded that, although rare (with a prevalence of only 2.7%), intra-articular calcifications are associated with both degenerative bone alterations and age.

  • Objectives: Parkinson's disease is one of the most common neurodegenerative diseases in the elderly population. In order to estimate the prevalence of Parkinson's disease in the community, the application of a good screening tool is essential. We evaluated the validity and reliability of a Parkinson's disease screening questionnaire and propose an alternative measure to improve its validity for use in community surveys. Methods: We designed the study in a three-phase approach consisting of a screening questionnaire, neurologic examination, and confirmatory examination. A repeated survey was administered to patients with disease detected in the community and on 150 subjects. We examined internal consistency using Cronbach's alpha test, test-retest reliability using the kappa statistic, and validity using sensitivity, specificity, and ROC curves. Unadjusted odds ratios were utilized for the estimation of weights for each questionnaire item. Results: The Cronbach's alpha of the questionnaire was 0.708. The kappa statistic for test-retest reliability was good to generally fair in most of the items. When newly proposed weighting scores were used, the optimum cut-off value was 7/8. When cut-off value was 5/6 for surveying prevalence in a community, the sensitivity was 0.98, and the specificity was 0.61, with simultaneous improvement in reliability. Conclusions: We recommend 5/6 as the ideal cut-off value for the survey of PD prevalence in community. This questionnaire designed for the Korean community could help future epidemiologic studies of PD.

  • Recently, a total of 74 Staphylococcus pseudintermedius isolates were collected from clinical cases of canine pyoderma and otitis externa in Korea. In this study, we examined in vitro fluoroquinolone resistance among those isolates using a standard disc diffusion technique. The results demonstrated that, except for one isolate, approximately 18.9% to 27.0% of the isolates possessed bacterial resistance to both veterinary- and human-licensed fluoroquinolones including moxifloxacin (18.9% resistance), levofloxacin (20.3% resistance), ofloxacin (24.3% resistance), ciprofloxacin (25.7% resistance), and enrofloxacin (27.0% resistance). Most surprisingly, 14 out of 74 (18.9%) isolates were resistant to all the five fluoroquinolones evaluated. Moreover, a PCR detection of the methicillin resistance gene (mecA) among the 74 isolates revealed that 13 out of 25 (52.0%) mecApositive isolates, but only 7 out of 49 (14.3%) mecA-negative isolates, were resistant to one or more fluoroquinones. Taken together, our results imply that bacterial resistance to both veterinary- and human-use fluoroquinolones becomes prevalent among the S. pseudintermedius isolates from canine pyoderma and otitis externa in Korea, as well as that the high prevalence of the mecA-positive S. pseudintermedius isolates carrying multiple fluoroquinolones resistance could be a potential public health problem.

  • Human papillomavirus (HPV) infection is considered to play a critical role in the development of cervical carcinoma, which is the third most common cancer among Korean females. Here, we performed a baseline study of HPV infection and genotyping using an HPV DNA chip, which is a type of oligonucleotide microarray. A total of 6,855 cervical swab specimens from 5,494 women attending Dankook University Hospital Health Improvement Center in Cheonan, Korea between 2006 and 2012, originally collected for HPV infection screening, were genotyped for HPV. The extracted DNA from the cervical specimens was investigated by an HPV DNA chip designed to detect 41 different HPV types. HPV was identified as positive in 1,143 (16.7%) of the 6,855 samples. The most frequently detected HPV genotypes were HPV types 16, 53, 56, 58, 39, 52, 70, 84, 68, 62, 35, 54, 81, 18, and 30, in descending order of incidence. The proportions of single and multiple HPV infections in the HPV-positive specimens were 78.1% and 21.9%, respectively. The average age of HPV-positive patients was 39.9 years, with the positive rate of HPV being the highest in the 10-29 age group (20.6%). We report here on the prevalence and distribution of 41 different genotypes of HPV according to age among women in Cheonan, Korea. These data may be of use as baseline data for the assessment of public health-related issues and for the development of area-specific HPV vaccines.
