21세기가 눈앞에 다가섰다. 마음 설레는 일도 많겠지만 컴퓨터의 경우는 매우 긴장하고 있다. 이른바 "밀레니엄 버그"(millennium bug; 일명 Y2k)라고 불리는 컴퓨터의 반란이 예상되기 때문이다. 세계 각국이 비상한 관심속에 문제해결에 착수했고 우리나라도 국무총리실을 중심으로 범 국가적 차원에서 대책을 준비하고 있다. 그러나, 이제사 인식의 단계에 머물러있는 우리나라의 경우는 밀레니엄 버그 해결에는 최소한 시험기간을 포함하여 1년 6개월은 필요하다는 여러 경험담을 고려한다면 조금도 지체할 수 없고 시행착오조차 허락하지 않는다. 시행착오는 곧 실패를 의미한다. 따라서 막차를 타게 된 우리는 뒤돌아 볼 수 없는 숨막히는 일정을 앞에 두고 있다. 본 고(稿)에서는 밀레니엄 버그란 무엇이며, 이를 해결한 국내외 경험에 대한 소개 이를 종합한 후 중소기업을 위한 대책을 정리하는 순서로 싣는다.

The authers have experimented in order to measure the tensile strength limit of orthodontic bracket attached with DBS to tooth surface with fluoride application. 20 incisal teeth, 20 premolar and 20 molar teeth have been selected for the experiment and the half of the teeth have been applied with 2% NaF solution with electric stimulation and the rest half of the teeth have been natural. Each bracket have been attached to all experimental teeth through DBS method. And then, each experimental brackets have been removed with instron and measured the tensile strenght limit and observed removal portion. The obtained results were as followings; 1. there was no significant difference at relative tensile strength limit between natural group and fluoridated group in anterior teeth. 2. There was no significant difference at relative tensile strength limit between natural group and fluoridated group in premolar teeth. 3. There was no significant difference at relative tensile strength limit between natural group and fluoridated group in molar teeth. 4. The relative tensile strength limit was the most in premolar teeth and the least in molar teeth both in natural and fluoridated groups. 5. The method for attaching DBS bracket well to tooth surface was suggested because the removal portion of DBS brackets from the teeth were mostly at between resin and bracket surface. 6. It was recommended that fluoride application must be done to orthodontic patient with DBS bracket for preventing the dental caries.

This study was conducted to examine aspects of middle and high school students' drinking and smoking with analysis of related factors. The subjects of this study was 540 students in Kyungbuk Province. Data were collected from July, 2002 to September, 2002. The results of this study can be summarized as follows. 1. 43.6% of the boy students experienced smoking, while 12.2% of the girl students experienced it. 5.3% of the students at academy schools experienced smoking, while 44.7% of the students at vocational schools experienced it. 11.4% of the middle school students experienced smoking, while 33.9% of the high school students experienced it. 15.5% of them who lived in towns or villages experienced smoking and 38.3% of them who lived in small or medium sized cities experienced it.37.5% of the students who belonged to the lower economic class experienced smoking and 20.7% of the students who belonged to the upper economic class experienced it. 24.0% of the students who belonged to the middle economic class experienced it. It appears that the respondents showed significantly different smoking experience rates by gender, school types, grades, the number of family members, residences, and economic classes. 2. 14.5% of the respondents who lived with grandparents and parents experienced smoking and 26.5% of them who lived with parents experienced it. The smoking rate was significantly high in the groups of having one-parent, being unsatisfied with family life, making poor grades in studies, and having the father or the mother working as a salesperson. 3. 45.3% of the respondents who were unsatisfied with family life experienced smoking. The smoking rate of the respondents who were unsatisfied with it was significantly higher than that of the other groups. On the other hand, the smoking rates were not significantly different by daily life, schoolmate relation, health condition, and feeling stress. 4. According to smoking rate by frequency of drinking, 16.4% of the respondents who drank less than once a month smoked and 54.8% of them who drank more than twice a month smoked. The more frequently they drank, the higher their smoking rate was. Those who did exercise displayed significantly higher smoking rate than those who did not do exercise. Among the rates of the respondents' agonies, family disharmony was 50.5% and love problem was 39.2%. Economic condition preblem was 34.6%. It appeared that smoking was most influenced by the family disharmony. 5. The factors significantly influencing smoking experience were gender, school grade, schoolmate relation, score in studies, and exercise. From above results, it can be concluded that the students' smoking is a serious problems which can be resolved by simple approaches because it is interrelated complicatedly with gender, grade, family, school, etc. Schools, related organizations, and the government must closely work together to maximize the effectiveness of policy implementation concerning the smoking and drinking problem of the middle and high school students.

We are now speaking that today is information society. The character of information society is regard information as assets quiet wellenergy. Information systems of these days is based by computer which is said tool for works of human knowledge. But now computer fraud is rising by weakness of computer. Therefore I am going to study on the design for data protection in data process system by com-putor.

In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.
