N/A Background: Magnetocardiogram (MCG), which records the changes of magnetic fields generated by the heart`s electrical activity, theoritically can provide unique data for clinical application. To date, MCG has been investigated only at a single time point after myocardial infarction (MI) with severe left ventricular dysfunction in rats. The purpose of the present study was to investigate sequential changes of MCG after MI and to evaluate effects of infarct size on MCG. Methods: Acute MI were induced by the permanent ligation of left coronary artery in 22 rats. Magnetic fields were recorded just above a rat with Nb Superconducting Quantum Interference Device (SQUID) gradiometer inside a magnetically shielded room. MCG was measured before and immediately after surgery and it was subsequently recorded at the time points of 1, 4 and 6 hours post operatively. MCG was also measured at 1, 3, 7 and 21 days after surgery. Results: Elevation of ST segment and appearance of pathological Q wave on the MCG were evident immediately after the ligation of coronary artery and persisted to 6 hours after MI. On MCG, ST segment was depressed and T wave was inverted from 1 day after MI. In rats with small-and moderate- sized MI (infarct size〈30%), ST depression returned to near the isoelectric level and Q wave disappeared from 7 days after MI. However, ST depression and Q wave were still present in rats with larger infarct (infarct size≥30%). Conclusion: Evolutional changes of MCG were well-recognized up to 21 days after MI. Furthermore, the infarct size can be expressed by the extent of Q wave and ST segment depression on MCG. Taken together, these data indicate that MCG is a helpful modality for the diagnosis, evaluation of infarct size and follow up after MI.(Korean J Med 62:42-48, 2002)

본 논문의 목적은 대학생의 인터넷 중독에 영향을 주는 요인에 대한 분석을 통해 대학생의 정신건강을 위한 공적프로그램 도입에 대한 함의를 제공하는 것이다. 분석자료는 을지대학교 강남 을지 병원 중독연구소에서 대학생 453명을 대상으로한 설문지이다. 설문조사에 사용된 설문지는 인터넷 중독을 측정하는 인터넷 중독 척도(Young척도), 불안을 측정하는 불안척도(STAI)와 우울을 측정하는 Beck의 우울척도(BDI)로 구성되었다. 분석결과 첫째, 연령 및 학년은 인터넷 중독에 유의미한 영향을 미쳤다. 둘째, 나이가 어릴수록, 학년이 낮을수록 불안과 우울에 빠지기 쉬웠다. 셋째, 무엇보다 불안이 대학생의 인터넷 중독에 가장 큰 영향을 미치는 요인이었다. The purpose of this research to suggest implications on introduction of public-program for college students` mental health through analysing the factors which impact on internet addiction of college students. The analysing data is questionnaire intended to 453 college students in Kang- Nam Eulji hospital addiction institute. The questionnaire consisted of internet addiction scale (Young-scale), anxiety scale (STAI) and depression scale (BDI). This study reveals three main findings. Firstly, age and grade have an effect on internet addiction. Second, the younger, the lower grade, they are likely to be depressed and anxiety. Third, most of all, the anxiety has the most effect on internet addiction of college students.

바나듐과 크롬의 쿠페론 착물의 전기화학적 행동을 아세트산 완충용액(pH 5.0)과 붕산염 완충용액(pH 9.5)에서 조사해 본 결과 크롬-쿠페론 착물의 환원봉우리전위(E_(ct)^(p))가 쿠페론의 봉우리전위(E₁^(p))보다 작다 (E_(ct)^(P) < E₁^(P)). 붕산염 완충용액에서 크롬-쿠페론계의 전도된 봉우리가 크게 나타나는 것은 E_(ct)^(P)와 E₁^(P)의 차이가 큰 때문인 것으로 생각된다 (ΔE = 0.40V). When the peak potentials of V-cupferron and Cr-cupferron complex compare at both buffer solution(pH 5.0 and pH 9.5), the peak potential of Cr-cupferron(E_(ct)^(P)) is smaller the peak potential of cupferron (E₁^(P)) at both buffer solution (E_(ct)^(p)) < E₁^(p)). The appearance of larger inverted peak of Cr-cupferron in borate buffer solution results from large difference of E_(ct)^(p) and E₁^(p) (ΔE=0.40 V).

In this study, physiological responses and subjective sensations were investigated depending on various high school girls' lower cloth uniform in winter. Four healthy young women were selected, and they wore same underwear and jacket. The types of lower cloth were tight skirt+stocking, flared skirt+stocking, tight skirt+legings+socks, flared skirt+legings+socks, and slacks+socks. The results were as follows: 1) The effect of the type of lower cloth in winter on the skin temperature, humidity inside clothing and subjective sensations were significant. 2) It is desirable for high school girls to wear slacks in winter, Since physiological responses and subjective sensations of slacks are superior to those of skirts. 3) It is desirable for high school girls to wear flared skirt, legings, socks in winter, Since insulation and subjective sensations of flared skirts are superior to those of tight skirts.

The effect of Carbontetrachloride administration on Lactatedehydrogenase isozyme patterns were analyzed by cellulose acetate electrophoresis for the brain, heart, kidney, lung, liver and mouse muscle. Each other tissue was found to have a characteristic distribution of these isozymes. At normal condition, aerobic tissue such as brain, heart, kidney, and lung were found to have all five isozymes from LDH_1 to LDH_5, while anaerobic tissues such as liver and muscle were found to have superiorly LDH_5 The toxicity of Carbontetrachloride administration was most prominence in the liver, and lung toxicity was occured also.

This study was conducted to investigate the pasting properties of waxy corn ‘Ilmichal’ during ripening with different sowing date. Starch content of Ilmichal was increased as matured (p<0.05). Analysis of pasting properties with waxy corn starch using a rapid visco analyser (RVA) showed linear changes in peak viscosity, trough viscosity, final viscosity, breakdown and consistency according to ripening. There were significantly positive correlation between starch content of Ilmichal and peak viscosity (0.39*), trough viscosity (0.58***), final viscosity (0.58***), and consistency (0.57**). Differential scanning calorimerty (DSC). The enthalpy of gelatinization was increased as ripening. But onset and peak temperature were decreased. There were significantly positive correlation between starch content of Ilmichal and onset temperature (0.44*), peak temperature (0.38*), and completion temperature (0.59***), on the other hand, crude protein content presented significantly negative correlation between completion temperature (-0.41*).
