For the graceful design and durability, cellular phone frame is been changing from the external to internal. Most of external frames are made by aluminium alloy, because that is required to be light and cheap while that should be hard. Due to the mass product using injection molding method or die casting method, these external frames have a lot of burrs. Moreover, microscopic burrs affect for parts badly, how that makes electric jamming. In addition, microscopic burrs could injure workers or users. In this paper, for the removal of microscopic burrs on the cellular phone external frame, electrochemical deburring is conducted and electrochemical conditions are researched.
어머니가 인식하는 양육자신감과 아기행동 특성과의 관계 연구
신영희,박언아 대한보건협회 1999 대한보건연구 Vol.25 No.2
본 연구는 어머니의 양육자신감과 아기행동 특성과의 관계를 알아보기 위한 것으로 T광역시 소재의 K대학교 부속병원 영유아상담실에서 신생아 예방접종을 위해 방문한 94명의 산욕기 산모를 대상으로 설문조사 하였다. 연구도구는 Wolke와 St. James-Robert(1987)가 개발한 '어머니와 아기에 관한 척도(Mother and Baby Scale: MABS)'를 한국어로 번역하여 사용하였다. 본 연구를 통해서 얻은 주요 결과는, 연구 대상 어머니들의 신생아 양육에 대한 자신감 부족 정도는 보통정도 수준이었으며 (평균 24.2점/55점) 어머니의 양육자신감 부족과 신생아의 보채는 행동과는 긍정적 상관관계가 있었다(r=.50, p=.00). 어머니의 자신감 부족은 신생아들에게는 부정적인 행동으로 반영되는 것으로 사료된다. This study was carried out to assess the relationship between perceived maternal competence in child care and behaviors of their infants. Ninty four postpartum mothers visiting child health clinic for routine vaccination for their babies were recruited for the study. Data analyses were based on a self-report of Mother and Baby Scale(MABS: Wolke and St. James-Robert,1987) completed by each mother. The major finding can be summarized as follows' the level of maternal competence was moderate(average 24.2/55 points). Lack of maternal competence was significantly positively related to infant's irritability (r=.50, p=.00). This appears to mean that mother's inexperience or psychological indecisiveness may be sensed by their infants and that those may have been reflected to the infant's behavior as an irritability.

Two cases of verminous arteritis were chosen for this case. These horses were originally submitted for necropsy in the Cheju horse race. Case 1 : At necropy, there was increased ascite, thickened ab-dominal aorta at junction of cranial mesenteric artery. In the aorta, there was a long thrombus embed-ded with strongylus vulgaris larvae. Some larvae were also firmly attached in the aortic intima Histologically, there was infiltration of neutropliils, eosinophils, and macrophages in the tunica media. At the junction of thrombus and arterial intima, there was proliferation of vessels. Case 2 : At necropsy, there was thickened abdominal aorta, which showed typical verminous arteritis with thrombus. Histologically, ceseous tissues with haematopoietic tissue was recognized in the aortic wall.

Sewage sludges generated from municipal sewage treatment plants in the Pusan metropolitan city were used for studying the metal distribution in the incinerated sludge. In order to accomplish such goal, sequential extraction procedure was adopted. In the comparison of heavy metal contents for dewatered sewage sludges from three sewage treatment plants, the J plant, which treats wastewater from metal plating, dyeing, and tanning industrial complexes, showed the highest content of Cu, Cd, Zn, Hg, and Cr among three plants. The result of the sequential extraction, which was used for evaluating the leaching possibility under landfill environment, showed that the leaching possibility had in the order of Cd> Mn> Cu Pb > Zn > Cr.

The shear capacity of reinforced concrete beams is characterized by various parameters as the strength of concrete, the shear-span ratio, the strength of shear reinforcement etc. Sixteen specimens were tested with those variables. All specimens showed the shear failure mode to accompany the diagonal shear cracks or the flexural failure. Through the experimental works, it was evidenced that the shear strength depends on the strength of concrete, the shear-span ratio, the confinement index including the strength and spacing of shear reinforcement bars etc. Although part of test results could not distinct the effects of test variables due to the yielding of longitudinal bars, it was shown that they almost satisfy the ACI code except several specimens confined by high-strength shear bars.

Ultrasound is very useful in evaluation of obstructive jaundice. We retrospectively evaluated the useful findings of ultrasonography in differentiating benign extrahepatic duct obstruction from malignant diseases. Among the 36 patients, 25 patients were benign extrahepatic obstruction and 11 patients were malignant obstruction. The shapes of extrahepatic dilatation were classified into fustiform, meniscus, and abrupt cut off by bowel gas. The diameter, length, and bile duct wall-interface were compared between benign and malignant groups and serum bilirubin and alkaline phosphatase were also compared between two groups retrospectively. The results were as follows. The most common form of extrahepatic dilatation was meniscus(10 of 26 patients, 38%) in benign obstruction, and fusiform(8 of 11 patients, 73%) in malignant obstruction. No significant difference was noted in diameter, length, serum bilirubin, and alkaline phosphatase between benign and malignant groups. Only one case showed decreased bile duct wall-interface in benign obstruction, but loss or decrease of bile duct wall-interface were 8 patients in malignant obstruction. The combined findings of fusiform dilatation and loss of bile duct wall-interface in ultrasonography will be helpful in differential diagnosis of malignant extrahepatic bile obstruction from benign conditions.

The current study evaluates the capacity of Caryophylli Flos water extract(CFWE) to regulate immediate allergic reaction by control of histamine release. CFWE was found to exhibit a ingibitory activity on the compound 48/80-induced anaphylaxis. CFWE inhibited the serum histamine release induced in anaphylaxis by compound 48/80. CFWE was also showed a dose-depent activity on the conpound 40/80-induced histamine release from the highly purified population of Alcian Blue-positive peritoneal mast cells. This result suggest that CFWE may be useful for the prevention and treatment of allergy related disease.
