BACKGROUND: Internet use is taking place as a necessary part in modern life. Recently, internet use among adolescents has bocome a prominent social problem. In accordance with assessment of internet using pattern and addiction, this study analyzed addiction, this study analyzed addiction-relating factors. According to analysis of intimate relating factor, this study attempted to provide appropriate countermeasure. METHODS: The author had performed physical examination on the subjects on May, 2001. The subjects were elementary, middle, and high school students. Among them, 913 students were surveyed with questionnaires. Among the 193 students, elementary school students were 222, middle school 369, high school 291, and 31 did not complete the survey. Addiction-relating factors were sex, age, frequency, mostly connected web-site, time, and place. Young's scale was used as internet addiction assessment, 70 points, and above were used as criteria for internet addiction. RESULTS: There were 32 addicted students among the subjects. By sex, male students were 7, female students 25. By age, elementary school student was 1, middle school students 9, and high school students 22. In frequency, 424 students used the internet more than 5 times per week among all subjects. 30 students used the internet more than 5 times per week among addicted students. CONCLUSION: Internet use of chatting sire is an intimate addiction-relating factor. Therefore, substitute activity which can reduce computer using time, and frequency should be encouraged. Especially, avoiding chatting site is considered a preventive methive of addiction during the computer using time.

Any strenuous muscular exercise may trigger rhabdomyolysis. We report an episode of clinically manifested exertional rhabdomyolysis due to stationary cycling, commonly known as spinning. Reports of spinning-related rhabdomyolysis are rare in the English literature, and the current case appears to be the first such case reported in South Korea. A previously healthy 21-year-old Asian woman presented with severe thigh pain and reddish-brown urinary discoloration 24–48 hours after attending a spinning class at a local gymnasium. Paired with key laboratory findings, her symptoms were suggestive of rhabdomyolysis. She required hospital admission to sustain renal function through fluid resuscitation therapy and fluid balance monitoring. Because exertional rhabdomyolysis may occur in any unfit but otherwise healthy individual who indulges in stationary cycling, the potential health risks of this activity must be considered.

BACKGROUND: Psychiatric disorders have been known to occur by the interaction of biologic, psychologic and social factors. A family can affect the occurrence of psychiatric disorders as a primary social factor. On the other hand, psychiatric disorders can affect family function. There fore, we studied to compare family function between the families of psychiatric inpatients and those of normal persons, using Family APGAR and FACES III. METHODS: Between July 1, 1999 and August 31, 1999, we examined the subject group as 40 relatives to visit psychiatric inpatient and the control group as 40 persons whose family members did not have chronic diseases or psychiatric disorders, using questionnaire of socio-demographic factors and family function. RESULTS: Family APGAR scores in subject group were lower than those of control group, but not statistically different. But the degrees of 'Partnership' of the Family APGAR in subject group were significantly lower than those of control group.(P<0.05) Adaptability scores of FACES III in two groups were not different. Cohesion scores of FACES III in subject group were lower than those of control group but not statistically different. The Family APGAR scores in the families of the schizophrenics were significantly lower than those of control group. The duration of psychiatric disorders did not affect family function. CONCLUSION: The family function of subject group was worsened but not statistically different. But in the families of the schizophrenics, the Family APGAR scores were significantly lower than those of control group. Therefore, we should consider serious family dysfunction in the families of schizophrenics.

BACKGROUND: For an early detection and prevention of dementia, there are growing concerns about the high-risk group for dementia and mild cognitive impairment. With an increase of obesity and its complications, obesity has become a major public health problem. Therefore, the aim of this study was to investigate the relationship between obesity and the high probability of dementia. METHODS: This study was done with subjects aged 60 to 89 years who visited a health promotion center, from April 1, 2008 to April 30, 2008. A total of 293 subjects (164 males and 129 females) were included in the evaluation of cognitive function using the Korean version of the Seven Minutes Screen test. Logistic regression models were used to analyze the association between obesity and the high-risk group for dementia. RESULTS: Among a total of 293 subjects, 71 subjects (29 males and 42 females) had a high probability of dementia. When compared to normal body mass index (BMI) group, overweight and obesity groups had about a 2.2-fold and 2.4-fold higher probability of dementia (95% confidence interval [CI], 0.97 to 4.99 and 95% CI, 1.07 to 5.46, respectively). When compared to non-obese and non-abdominal obesity group, non-obese and abdominal obesity group and obese and abdominal obesity group had about a 1.5-fold and 2.0-fold higher probability of dementia (95% CI, 0.59 to 3.95 and 95% CI, 1.09 to 3.84, respectively). CONCLUSION: This study shows that as the BMI increased, subjects had a higher probability of dementia; additionally, it suggests that abdominal obesity could be related to a higher probability of dementia.

PURPOSE: Multimedia can be used to understand the basic anatomy and pathological features of the bladder, providing more intuitive knowledge than traditional education methods. Cystoscopy is one of the most fundamental and important diagnostic procedures for detecting pathology in the bladder. Thus, we developed a PC-based digitalized recording device and electronic document to create an electronic medical record to perform cystoscopy and used them for medical education. METHODS: To share them with an educatee, cystoscopic images from a camera unit were shown on the monitor of a personal computer, which was installed with an interface device with an S-VHS input. With these cystoscopic images, the operator could provide some information on important structures in the bladder, such as bilateral ureteral orifices, the verumontanum and the trigone to the educatee. Also, simple questionnaires were given to medical students to evaluate the effectiveness and value of this system. RESULTS: Cystoscopic images could be transferred to the monitor with considerable ease and quality through the personal computer. This system was effective and valuable in teaching the normal anatomy and pathology of the bladder. Also, based on the results of the questionnaire, we concluded that this system provides high-quality images that are sufficient to relay medical information and is superior to traditional methods with regard to educational effectiveness and increasing one's understanding of medical diseases. CONCLUSION: The PC-based recording system for cystoscopy substitutes for commercial recording devices for medical purposes, and provides sufficient medical information to medical students to allow them to understand the normal anatomy and pathological structure of the bladder.

BACKGROUND: The author surveyed and analyzed the changes of perception and satisfaction about family medicine. So that the outcome may bring us a reference to advance family medicine more. METHODS: 247 in and out patients in one general hospital in Seoul were surveyed by the questionnaire from July 26, 2000 to June 20. The date was analyzed statistically by SAS program. RESULTS: As for the knowledge of family medicine, 61.5% of the patients answered that they knew what it is, and the most of them, 54%, via medical institution. The office workers, married , and highly educated people tend to know more about family medicine (P<0.05). As for attitude, 68% of the group answered that family medicine is necessary, because "family medicine doctors give proper advice and consult through out all fields of medicine"(58.8%). As for the preference so prirate doctor, 56.7% of the group answered that they would register for family medicine clinic, and students and office workers are fond of family medicine(P<0.05). As for the satisfaction, 34.4% were ever been to family medicine clinic, and 35.5% out of them were dissatisfied, mainly due to the lack of knowledge of physicians about their diseases(70.1%). CONCLUSION: The perception of family medicine are still scanty compared to the old studies.

BACKGROUND: Smoking is the single most considerable factor, which may likely affect one's health most adversely. Therefore, an effective control upon smoking has been the most important issue for all of the practitioners. Furthermore, the latters concern an the alternative medicine has been steadily mounting these days. Accordingly, a series of clinical group study has been mapped aut in order to clarify the effect and the outcome of acupuncture treatment and its rate of success. METHODS: The survey has been conducted fram April 7th, 1998 for six months with the voluntary help of 130 students as our study objects, who were the 1st, 2nd and 3rd graders at two metropolitan high-schools in Seoul A basic questionnaire has been prepared and collected at the first interview. The acupuncture treatment has been alternately administered at each side of ears once a week for the respective object-students and the information had been questioned in the survey. When 5 months lapsed with no treatment after the initial four weeks of intensive application, a further follow-up survey was repeated all over again(once every week for 4weeks and another after 6 months). For the analysis of our finding, the SAS V6.12 has been used together with the one way ANOVA test, t-test, and Cochran-Armitage trend test. RESULTS: Those who managed to stop smoking after the acupuncture treatment of one week, four weeks and six months respectively were found as follows; 2 students(61%), 12 students(37.5%), and 8 students(25%), proving that the success rate for smoking cessation after six months was 25%. Those who decreased their number of smoking more than half were; 13 students(39.4%), 15 students(46.9%), 25 students(75%). The number of withdrawal symptom and the smoking cessation as well as the smoking reduction rate were not found co-related each other. The frequency of their smoking, the frequency of the smoking attempt, the period of their abstinence from smoking, the facts whether their family-members of relatives smoked or not, the FTQ(Fagerstrom Tolerance Questionnaire), the frequency of their drinking and the motivation types of smoking(Why test) were found not influential upon the change of smoking tastes and their intensity of smoking wish by the treatment of the auricular acupuncture. CONCLUSIONS: The change of smoking taste and the change on the intensity of smoking wish as the outcome of acupuncture treatment for the stop-smoking has been statistically siganificant.

BACKGROUND: In Korea, the separation of prescribing and dispensing medicine was finally accepted as a medical policy in July, 2000, after a long period of discussion and study which was started in 1963. Now a year after the policy started, we investigated the knowledge, attitude, and practice of separation of prescribing and dispensing medicine. METHODS: Information, concerning whether the policy was effectively carried out and well understood, were gathered from 383 patients, who visited an university hospital from August 20 to September 1, 2001. RESULTS: The results revealed that 73.1% of the subjects knew the policy precisely. However, only 1.6% of them could answer all four questions on the purpose of the policy. The old-aged, the low educated, the low socioeconomic groups and the residents in agricultural area revealed poor understanding of the policy (P<0.05). Among the total, 74.9% showed negative response toward the policy. Time and cost increment were 75.7% and 75.2%, respectively. Among them 61.1% revealed negative attitude towards continuance the policy and 93.2% revealed dissatisfaction of the policy. CONCLUSION: The knowledge of the policy was relatively high. However, negative attitudes prevailed on the continuance of the policy. Therefore, more solutions and better strategies for the problems of prescribing and dispensing medicine would be needed.
