연구목적 : 현재 야뇨증에서 흔히 보이는 문제행동이 야뇨증의 원인인지, 아니면 공존하는 동반된 문제인지에 대한 의견이 분분하다. 저자들은 이존 연구의 대상이 대부분 임상환자였다는 점을 감안하여 비임상군을 연구대상으로 하여 야뇨증 아동에서 흔히 보이는 문제행동이 무엇인지를 알아보고 이를 통하여 야뇨증과 문제행동간의 관련성을 밝히고자 본 연구를 시행하였다. 방법 : 충청북도 영동군 소재의 2개 초등학교 학생 1,421명중 야뇨증이 있는 72명을 환자군으로 하였고, 연령, 학년, 성별을 대비시킨 72명의 정상아동을 대조군으로 하여 수정된 아동행동조사표를 시행하였다. 결과 : 야뇨증 아동에서 불안-공포 척도, 우울 척도, 주의력결핍-과잉활동 척도, 비행 척도의 점수가 의미있게 높게 나왔다. 주의력결핍-과잉활동 척도의 점수는 성별과 학년에 관계없이 항상 의미있게 높게 나왔으면 남자와 고학년에서는 비행 척도가 의미있었고, 여자와 저학년에서는 불안-공포 척도가 의미 있었다. 결론 : 야뇨증 아동에서 다양한 문제행동이 존재한다는 것을 알았고 야뇨증 환자의 치료시 이런 문제행동들에 좀더 주의를 기울이고, 더 많은 관심을 가져야 한다는 것을 아게 되었다. This study was designed to evaluate the emotional and behavioral problems of nocturnal enuresis children(n=72) in general population. And this was compared with normal control children(n=72). The behavioral problems were assessed using a modified child behavior checklist(CBCL) parent form. The results indicated that enuretic children were rated significantly more anxious, fearful, depressed, inattentive, hyperactive, delinquent on the modified CBCL rating when compared to the age-, grade- and sex-matched normal control children. Finally, it was an impressive evidence that there exist many emotional and behavioral problems in children with nocturnal enuresis. KEY WORDS : Enuresis · Behavior · CBCL.

Bruner의 敎育理論의 槪括的 考察

全閏植,朴榮煥 부산대학교 1972 論文集 Vol.14 No.1

Jeromes Bruner's learning theory is considered to have come from a challenge of Russian scientific deveopment (Sputnic) and accordingly re-evaluation of John Dewey's theory. The writers reviewed the backgrounds, theorotical foundation and the limits of his theory in comparison with those of John Dewey's theory. Dewey emphasized empiricism on the foundation of pragmatism, while Bruner based his theory on the structure of knowledge from the standpoint of realism, especially neo-realism. Bruner regards knowledge as close inquiry of entity which lies in the object of study, but Dewey think knowledge as a result of learning by doing. Bruner viewed an instruction on the basis of learning about learning. He also insits on a branch curriculum or a spiral curriculum. He is confident of the unnecessity of readiness basing on the theory of Piaget's child development. He claims intrinsic motivation and transfer by structure in stead of traditional, extrinsic compensation in learning situation. There are a lots of points to be noted in his theory, but due consideration must be given before it is accepted in this society.

Multiple abnormalities of lipoprotein metabolism exist in patients with diabetes mellitus that could contribute to their enhanced susceptibility to atherosclerosis. Acipimox(5-methyl-pyrazine carboxylic acid 4-oxide, Farmitala Carlo Erba, Milano Italy) is a new potent and long acting(8h) antilipolytic agent, which has been derived from nicotinic acid. By lowering plasma and possibly skeletal muscle concentrations of non-esterified fatty acid, Acipimox may have a potential beneficial effect on glucose metabolism in patients with non-insulin dependent diabetes mellitus. The aim of this study was to evaluate the acute effect of Acipimox on hyperlipidemia associated with non-insulin dependent diabetes mellitus. 18 patients with non-insulin dependent diabetes mellitus were in the study. They had fasting plasma triglyceride concentrations above 250 mg/dl and cholesterol concentrations above 240 mg/dl. The level of triglyceride, cholesterol and glycated hemoglobin were significantly reduced after 8 weeks treatment of Acipimox. Adverse effects were noted in 3 patients, but it was transient with the course of administration. Acipimox is an effective and safe drug for the management of hyperlipidemia associated with non-insulin dependent diabetes mellitus.

The Bi₂Sr₂CaCu₂O_(8)+_(δ) single crystals are grown from the melt using a stoichiometric starting composition fer the cautions. The size and thickness of the Bi₂Sr₂CaCu₂O_(8)+_(δ) crystals depends on the cooling rate. The lower the cooling rate, the bigger and thicker the Bi₂Sr₂CaCu₂O_(8)+_(δ) crystals become. Bi₂Sr₂CaCu₂O_(8)+_(δ) X-ray diffraction(XRD) measurements of the single crystals were carried out using the radiation source of Cu Kα . In these Patterns only the (0,0,2n) diffraction appeared. The result indicated that the cleared surface of the single crystal was of the a-b face, and that the single crystal had a single phase without any undergrowth with 7K and 85K phases. In addition, although the figure is not shown, XRD patterns from (006) to (00□) were observed in the range of 2θ=0 to 60 degrees. The characterization of as-grown single crystals have been analyzed by Laue X-ray backsdattering along the c-axis and X-ray precession experiments. The result of magnetic moment vs Tc in 10 Gauss for a crystals were measurements indicated that the samples have a superconducting transition temperature of 85K.

Single crystals of CdTe were grown by Bridgman method from a melt. They were contained the element of 0.1, 0.15, 0.2mole % In and 0.1mole % P as a dopant respectively. The crystallographic direction of the grown CdTe have zinc blende structure which is(331) plane 2θ=62.6。 in X-ray method. The etch pits on the (100), (110) and (111) surfaces grown to characteristics shapes with E-Ag or PBr was found to consider with the crystallographic direction denoted by simple Miller indices as is depicted schematically. Here the pits on (100), (110) and (111) show rectangular, triangular and conical shapes respectively. The results of PL measurements of undoped and In-doped CdTe showed the maximum peak at 7475 Å and 7503 Å, and P-doped CdTe by thermal diffusion showed the maximum peak at 6943 Å and 7478 Å , the former was shown by Al and the later by phosphorous. The values of the electrical chracteristics have been compared with the Yamada's and we showed the good agreements between them. The thickness if Al thermal diffusion to the CdTe crystals were propotional to the diffusion time. The properties of these cells have good rectification with forward and reverse voltage.

김영건,전준식,구본정 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

To assess the relation between vibratory perception threshold(VPT) and diabetic neuropathy, we measured by means of a biothesiometer in 50 diabetics and 41 control subjects, and the following results were obtained. 1. In the control subjects, the VPT value was 4.5 at the left 2nd finger tip and 20.3 at the left calf, and there were no differences between the left and right. 2. Among the asymptomatic diabetic subjects, the VII' value was 9.1 at the left 2nd finger tip and 26.3 at the right calf. Among the symptomatic diabetic subjects, the VPT value was 10.8 at the left 2nd finger tip and 31.6 at the right calf, and there were no differences between the left and right. Symptomatic subjects had higher VPT values at all sites than those of asymptomatic subjects, especially in the left medial malleolus and the left calf(p<0.05). Control subjects had significantly lower VPT values at all sites than those of diabetic subjects(p<0.01). 3. In the difference in VPT between the sexes, control subjects had significantly higher VPT values at the left lateral malleolus, the right and left medial malleolus in males than those of females(p<0.05), diabetic subjects had significantly higher VPT values at the left 2nd finger tip, the left and right ulnar styloid, the right and left Ist toe base in males than those of females. 4. There were positively correlated at the VPT values with age in the diabetic and control subjects. 5. There were not correlated at the VPT values with the metabolic controlin the diabetic and control subjects. 6. There were relatively positively correlated at the VPT values with duration in the asymptomatic diabetic subjects than those of symptomatic diabetic subjects. These results suggest that measurement of VPT provides a quick and reliable assessment of diabetic neuropathy, gives an objective measure of the progress of diabetic neuropathy.

While braking cars, a large amount of energy is taken into the brake system in a short period of time. This leads to some problems ; cracking of the disc, non-uniform wear of pad and disc, fade. Thus it is important to measure the contact thermal behaviour precisely between disc and pad. The measurements must be considered to design the brake system. The paper describes methods to analysis the problem of the thermal behavior on the ventilated disc with ANSYS-a program of FEA and a brake dynamometer. According to this way, the paper can present the error between the data by the dynamometer and the results of analysis by ANSYS.

Antioxidative activities (AA) of mustard leaf kimchi (MLK) by the addition of optional ingredients among selected minor materials were studied. In order to determine AA of MLK with different spices, the model systems of ground cooked beef with green onion, garlic, and red pepper powder were prepared and stored for 4 weeks at 4℃. AA of red pepper added group was stronger than those of others. AA of red MLK was relatively higher than that of (green) MLK. For the enhancement of AA of MLK, another model systems were prepared with the selected antioxidative optional ingredients, which were bonnet bellflower root, leek, burdock, sea tangle, sea mustard, seastaghorn at the level of 2% or 4%. The extracts of water, 75% methanol and hexane of MLK, bonnet bellflower root added MLK, and seastaghorn added MLK had a considerable AA with the inhibition of peroxide formation during the autioxidation of linoleic acid mixtures in aqueous model systems at 37℃. Therefore, AA was more effective in MLK containing specific optional ingredients than that of MLK alone significantly.
