The purpose of this study is to grasp nutrition knowledge and lactation attitudes of mothers in lactation now and to be basic data which encourage breast-feeding in future. The subject of this study was 106 mothers of infant in lactation until 15 months old after delivery in Daegu Area (Naedang-dong,Sungdang-dong)and Dalsung Area (Hyeonpoong-myeon,Yuga-myeon, Guji-myeon.) All participating mothers of infant were randomly chosen. The time of this study was conducted from January 5th to January 25th,1988. The method of this study was that the researcher visited with mothers of infant and interviewed with them using questionaire. The collected materials were analyzed using frequency distribution,percentage,mean,X²test (Chi-Square)and F-test. The results of this study were as follows ; 1. Conducting the F-test,the score of nutritional knowledge according to age, educational level and monthly incomes showed significant differences. The score of nutritional knowledge was shown to be high among older mothers, the well-educated, city-dwellers and people with high incomes. 2. In lactation patterns according to the score of nutritional knowledge, the groups with the lower score gave their infants breast-feeding, whereas higher scoring groups provided them with bottle-feeding. 3. The sources of information about nutition knowledge and weaning did not show significant difference between division of ages and education levels. 4. In educational level and resident area of mothers, the educational level of country dwellers was low, whereas the educational level of city-dwellers was high. 5. In lactation patterns according to mothers'age, the groups who were younger than 25years old gave their infants breast-feeding, whereas the groups who were older than 30years old provided them with bottle-feeding. 6. In lactation patterns according to educational level,the groups who had lower education gave their infants breastfeeding, whereas the higher educated mothers provided them with bottle-feeding. 7. In lactation patterns according to resident area, countrydwellers gave their infants breast-feeding, whereas city-dwellers provided them bottle-feeding. 8. In lactation patterns according to monthly income,the lower income groups seemed to have breast-feeding, whereas the higher income groups seemed to have bottle-feeding. 9. The time of onset of the weaning was found to be earlier in the old aged, the higher educated and city-dweller groups. 10. The time of the termination of the weaning was found earlier in higher educated, city-dweller groups.

목적 : 비교적 드물게 보는 선천성 심질환중의 하나인 팔로3징에 대한 본원에서의 진단 및 치료 경험을 임상적으로 관찰하여 보고함으로써 향후 이 질환의 개심술 성적을 향상시키는데 기여하고자 하였다. 대상 및 방법 : 경북대학교병원 흉부외과에서 1980년 3월부터 1997년 2월 사이에 개심술을 받았던 환자들 중에서 심도자검사 및 수술소견에 의해 팔로3징으로 진단되었던 8례를 대상으로 술전증상과 진찰소견, 술전의 심초음파검사, 심도자검사 및 심혈관조영술의 소견들을 검토하였고, 수술소견으로는 폐동맥협착과 심방중격결손의 해부학적 형태, 체외순환시간과 대동맥차단시간, 수술방법, 술후 합병증 및 수술사망률 등을 조사하였다. 그리고 평균 4.8년에 걸친 술후 추적관찰을 하였다. 결과 : 술전 진단에 있어서는 2례에서 오진되어 있었고, 술후 조기의 병원사망례는 없었으나 1례에서 류마치스성으로 추정되는 다발성 심장판막질환으로 8년후 인공판막치환술을 받았는데 패혈증으로 사망하였다. 나머지 환자들은 모두 양호한 경과를 취하였다. 결론 : 이 질환의 술전 진단에 있어서 과거에는 상당한 오진이 있었음을 알 수 있었고, 술전 증상이 심한 환자가 많았던 사실을 감안하면 개심술 성적과 술후 경과는 양호한 편이었다. Eight parients with trilogy of Fallot, characterized by the combination of pulmonary stenosism, atrial septal defect(ASD) and Rt-to-Lt shunt in the atrial level in the presence of an intact ventricular septum, underwent surgical correction between March 1980 and February 1997. Four patients were male and four were female. Their ages ranged from 2 months to 20 years with a mean age of 12.1 years. Cardiac catheterization and angiocardiogram were performed in all patients and 2D-Echocardiographic studies were obtained in 4 patients before operation. The preoperative diagnoses were tetralogy of Fallot(TOF) + ASD in 2 cases, trilogy of Fallot in 6 cases had combined pulmonary stenosis. The atrial septal defect was closed by primary suture in 6 cases and patch closure was done in 2 cases. The pulmonary stenosis was correctied by valvotomy in 2 cases, valvotomy + infundibulectomy in 2 cases, valvotomy + infundibulectomy + right venr tricular outflow tract reconstruction in one case, valvotomy + infundibulectomy + transannular patching in 3 cases. No operative death resulted, but one patient expired after undergoing mitral valve replacement and tricuspid annuloplasty for mitral insufficiency, tricuspid insufficiency and pulmonary valve insufficency 8 years later. All surviving patients have remained in good condition.

An analysis of objection request of individual public land price in the Choongju-city indicates that the ratio of objection request is higher than that of an average of the whole country. More than 70% requests out of the total objection request fields requests downward adjustment. Especially, it has been requested downward adjustment centering around a farm and forest land which are located on the town and township for the purpose of tax reduction. However, an objection request of individual public land price is not based on the absolute land value but based on personal interests. Thus, the downward or upward request without a fundamental rule tends to wastes the time and budget. As an alternative, there is need to introduce the scientific system, ALPA, which both selects a comparative standard land and applies land value ratification automatically. With the ALPA, it will increase the confidence of individual public land price. Furthermore, there will be only one time verification procedure before the determination·public announcement of individual public land price.

The hot deformation behavior of advanced reduced-activation alloy (ARAA) was investigated using hot torsion tests. Thefl ow stress decreased as deformation temperature increased and as strain rate decreased. The fl ow behavior demonstratedthe typical dynamic recrystallization (DRX). Based on the constitutive analysis of peak stress, the activation energy for hotdeformation was found to be 330.3 kJ mol −1 . Peak stress was analyzed as a function of the Zener–Hollomon parameter, andcalculated and experimental values were in good agreement. A DRX kinetic model for ARAA was derived with deformationconditions based on the Avrami-type model. It was confi rmed that the volume fraction of dynamically recrystallized grainsincreased as deformation temperature increased and as strain rate decreased. The necklace structure and grain boundarybulging were observed in the deformed microstructure of ARAA. The suggested DRX mechanism for ARAA during hotworking is discontinuous DRX.

Purpose : To acquire the useful diagnostic information through the analysis of the clinical and radiological characteristics of mandibular odontogenic keratocyst. Materials and Methods : The researchers compared and analysed the clinical and radiological features of 112 cases of mandibular odontogenic keratocyst confirmed by histopathlogic examination. Results : Mandibular odontogenic keratocysts occurred more frequently in males than in females and the incidence is the highest in the 2nd and 3rd decades. These cysts occurred in the mandibular posterior area, angle-ramus area and anterior area 51.8%, 31.2% and 17.0% respectively. These cysts had undulating border (69.6%) rather than smooth border (30.4%). Most of these cysts had well-defined hyperostotic border (94.6%). These cysts caused cortical thinning or expansion (78.6%) rather than no cortical reaction (21.4%). Loss of lamina dura was observed in 72.3%, displacement of tooth appeared in 35.7% and root resorption appeared in 12.5% of cases. In 71% of cases, displacement of mandibular canal was observed. Internal patterns of lesional radiolucency were even (61.6%) or uneven (38.4%). Conclusion : These results would be helpful in diagnosing of mandibular odontogenic keratocyst.

Plate heat exchangers have less limitation on space and weight because they can be small with higher heat transfer coefficients rather than air-cooled, shell-tube, and plate-fin heat exchangers. And, heat exchange can be efficiently performed even though the temperature difference of sea-water is small. They also have expense reduction effect in case that we use expensive materials for corrosion prevention and have merits of cleaning and changing design easily. So, plate heat exchangers are more suitable for evaporator and condenser of OTEC system.
