This study was conducted to investigate the differences in psychopathology and coping strategies among internet addictors, over users and non addictors in high school students. Subjects were 273 high school students in Seoul city. Self rating questionnaires included demographic data, Young’s Internet Addiction Scale, SCL-90-R, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory, and The Way of Coping Strategy. Subjects were classified into 3 groups (addiction, over use, non addiction) by Internet Addiction Scale score. Prevalence of internet addiction was 4.3% and male adolescents were more addictive than female. Students who were mainly involved with internet chatting or game showed higher internet addiction score. The addiction group and over use group showed higher level of somatization, obsession, interpersonal sensitivity, depression, anxiety, hostility, and paranoia than non-addicted group. Addiction group and over use group used passive coping strategies more frequently in the stressful situation than nonaddicted group. Also, the regression analysis for finding out causal factors that predicts internet addiction showed that emotion relieving strategy were important variable which predict internet addiction. Interpersonal sensitivity and emotion relieving coping strategy was important to predict addiction. This study showed that problematic internet use was closely associated with psychopathology and psychiatric comorbidity. And high interpersonal sensitivity and emotion relieving coping strategy were related with internet addiction in adolescence.

정보처리를 위한 컴퓨터교육의 학문적 기반 분석

신수범,이철환,김영기 인천교육대학교 초등교육연구소 2001 교육논총 Vol.18 No.-

현재 초등학교 컴퓨터 교육과정에 나타난 내용을 분석하여 보면 일반화 된 컴퓨터와 네트워크의 용도를 효율적으로 재구성하지 못하고 있으며 컴퓨터 교육과정과 그 이외의 교육과정에서 정보를 관리할 수 있는 내용으로 구성되어 있지 않다. 또한 소프트웨어의 기능 습득에 그치고 있으며 컴퓨터와 정보통신기술이 교육적 관점에서 재해석되어 있지 않고 전문적인 개념이 그대로 교육과정에 삽입되어 있는 형편이다. 이러한 점은 컴퓨터 교육의 기반이 되는 학문적 영역에 대한 연구가 새롭게 구성되어야 할 필요성을 제시하고 있다. 따라서 본 연구에서는 이와 같은 문제점을 해결하고, 컴퓨터 교육의 명확한 자리매김을 제공하기 위하여 컴퓨터 교육의 학문적 기반을 분석해 보고자 한다. There are two major curricula concepts of computer education. One is a kind of tool based curriculum that could enhance the quality of instruction and learning, such as, information and communication technology(ICT) in education, computer education as a tool, or computer/web based education. The other is a kind of content based curriculum that could handle what computer is and/ or how computer works. This is so called 'computer science education'. Because information technology has changed very rapidly and the related research is not enough, there have always been some gaps between theory and practice. When we carefully investigate the current curriculum of computer education, professionally organized contents in computer and network theory are used in elementary school. We need to re-organize the contents which is adequate to children. This situation implies it is very necessary to analyze current curriculum and setup a direction of computer education based theoretical approach in information processing area. Therefore, the main purpose of the study was to find out what computer curriculum should be changed and organized for elementary school teachers as well as students in computer education. The concept of computer education was summarized. The study surveyed and analyzed interdisciplinary subject areas related computer education, such as, computer science, information science, and cognitive science, etc.

오늘날 정보화가 빠르게 진행되면서 정보과학의 중요성이 수학, 과학의 중요성 못지않게 대두되고 있기 때문에 이 분야의 영재 역시 조기에 판별하여 교육시켜야 한다는 필요성이 강조되고 있다. 하지만 이에 대한 연구는 초보적인 단계에 머물고 있다. 이에, 본 연구에서는 영재의 판별에 대한 이론적 고찰을 통해서 영재의 특성, 정의 및 판별방법과 도구의 제작과정을 살펴보고 영재의 올바른 판별과정을 조사, 분석하였다. 또한 이를 바탕으로 정보과학의 기반이 되는 이산수학의 특성을 규정하여 이를 바탕으로 정보영재의 특성 및 정의를 내렸으며 이를 근거로 정보영재를 판별할 수 있는 도구를 제작하였다. 판별도구를 이용하여 적용한 결과 판별도구는 신뢰성이 있는 것으로 분석되었으며 향후 정보영재의 의미 있는 판별도구로 활용될 수 있을 수 것이다. Since the science of information is appearing no less important than mathematics and natural science as our society is rapidly becoming information-oriented, the necessity to distinguish prodigies of this field and to educate them as early as possible is also being emphasized. Unfortunately, however, the pertinent study is still in its beginning stage. In this study, I have reviewed the character, definition and method to distinguish prodigies and the procedure of developing a test, as well as researching and analyzing the proper process of distinguishing prodigies, through theoretical contemplation on the method of distinguishing the gifted children. Also, I have characterized and defined the information prodigies after clarifying the character of 'Discrete Mathematics' which becomes the basis of the science of information, paving the way to make a test method that can distinguish those information prodigies. As a result of our applying the system by using the distinction test, it turned out that the distinction test was pretty reliable. Accordingly, it can be utilized as a significant distinction test for information prodigies in the forthcoming future.

To elucidate the hematologic alterations in Korean hemorrhagic fever(KHF), hemoglobin concentration, reticulocyte percent, platetet count, fibrinogen concentration, fibrin degradation product(FDP), prothrombin time(PT) and partial thromboplastin time(PTT) were measured in 27 patients with KHF who were admitted to Chungnam National University Hospital from Oct. 1986 to Sept. 1988. The results were as follows 1. 19 patients(70.4%) out of 27 patients with KHF revealed petechial hemorrhage on axilla and soft palate. UGI bleeding, epistaxis and gross hematuria were also observed in 2, 2 and 2 patients, respectively. 2. In early phase of KHF, hemoglobin concentration showed normal in 21 patients (77.8%), reduced in 5 patients (18.5%)'and elevated in 1 patient. In late phase of KHF, it showed normal in 16 patients(59.3%) and reduced in 11 patients (40.7%). 3. Reticulocyte percent was significantly lower in early phase than late phase of KHF. 4, In early phase of KHF, peripheral blood leukocyte count was elevated in 23 patients(81.2%). In late phase, it became to normal in most patients. 5. In early phase of KHF, peripheral blood platelet counts was decreased in 24 patients (88.9%). In late phase, it became to normal in most patients. 6. In early phase of KHF, fibrinogen concentration was decreased in 3 (13.6%) out of 22 patients. In late phase it became to normal in all patients. FDP showed increased in 9 (40.9%) out of 23 patients in early phase of KHF and 2 (18.2%) out of 11 patients in late phase of KHF 7. PT showed normal range in all patients of early and late chase of KHF. In early phase, PTT was prolonged in 7 (29.2%) out of 24 patients and it became to normal in late phase of KHF.

Background : Coronary disease is highly prevalent in patient with end stage renal disease (ESRD) and account for much of their observed morbidity and mortality. Troponin-I consistently maintains a high sensitivity and specificity and is most sensitive marker for ischemic heart disease (IHD). Method : We examed 49 hernodialyzed patients (22 male, 27 female) without evidence of acute coronary syndrome (ACS) for 6 months. Biochemical markers were measured in serial predialysis blood samples. For analysis, we used two cardio-specific assays for troponin-T (cTnT) as well as for troponin-I (cTnI) and compared the results with CK-MB (reference value ≤ 4.0 ng/mL) concentration. Results : Myocardial ischemia was observed in 47% (23/49) of patients. cTnT level above 0.1 ng/mL. and cTnI level above 0.5 ng/mL, were observed in 22% (11/49) and 20% (10/49) of patients respectively. cTnI revealed significantly higher positive rate in patients with myocardial ischemia than the patients without myocardial ischemia (43 % vs 30%) (p<0.05). cTnT and CK-MB revealed no difference in positive rate between the patients with and without myocardial ischemia (cTnT : 30% vs 15% and CK-MB : 30% vs 19%). The sensitivity and specificity of cTnI to myocardial ischemia were higher than those of cTnT and CK-MB (sensitivity 43% vs 30% and 30%. specificity 100% vs 85% and 81%). Conclusion: Both cTnT and cTnI are useful in ruling out myocardial injury in chronic renal failure patients. But. cTnI is a more sensitivity and excellent specificity of ischemic heart disease than cTnT and CK-MB in hemodialyzed patients. In patients with ischemic heart disease, the presences of DM and advanced age were higher than those in patients without ischemic heart disease (p<0.05). Among the baseline characteristics old age, elevated LDH and diabeties were significant more frequent in the patients with elevation of cardiac troponin-I (p>0.5 ng/mL) than those with cardiac troponin-I (p<0.5 ng/mL), p=0.038, p=0.049, and p=0.045, respectively. Our results suggest that these cTnI is the potential diagnostic marker for the prediction of IHD in ESRD patients.

In this study, we made investigation into water permeation, solute separation, concentration and Na^(+), K^(+), Mg^(2+), Ca^(2+), Cl^(-), SO^(2)_(4)-, HCO^(-)_(3) ions separation of seawater by the revers osmosis process using a suitable semipermeable membrane. The different thickness of membranes were prepared. On heat treatment, temperature was 80℃ and thier effects were also investigated. The flat single module system was made to be capable of treating feed solution at 200-2000cc/min and 120 atm. The experimental results can be summerized as follows: 1) As the effective operating pressure increased, permeability of pure water proportionally increased. 2) As the exposure period of the manufactured membrane in air increased, permeation rate increased, but as the thickness of the membrane increased, permeation rate decreased. 3) The capacity for being reproductive of the manufactured membrane (CA: 30wt%, Formamide: 45wt%, Acetone: 25wt%) in their performance was less than 10-30% and agreed with that reported in the literature. 4) We could separated about 85-95% of salt ion in seawater using a flat single module system.

The purpose of this study was to evaluate the smoothing error of data before and after impact in sports movement according to smoothing methods based on physical inspect. The used smoothing methods are cubic smoothing spline. digital filter and wavelet and the technique to separate data before and after impact and to smooth the each data separately and the technique to skip data in smoothing process. At first. Using the math functions. theoretical data were made. Each smoothing methods with various parameters were applied to the data which were made with the various speed ratio and the relative angle between before and after of impact. Next time we use the method with optimal parameter to the experimental data, according to the speed ratio and the relative angle between before and after of impact. The results of this study were as follows: 1. It is effective to separate data at impact point and to smooth each data. Especially this is expected to have good result for velocity before and after impact. But, padding technique needs the accuracy of digitizing data before and after impact. 2. Sampling speed of data was important to obtain the accurate results. More skipping digitizing data. the error is larger. But the result to use 5-data before and after impact and skip randomly in the other data was nearly identical to the result to use all data for smoothing. 3. Spline method and digital-filter method of variation of parameter were large according to the state of impact and the separation technique, skip technique. but it was small on wavelet method. So, wavelet method can be used to smooth various kinds of data without cautions.
