This study was done to analysis data on breastfeeding mothers. This stud was conducted using data from telephone counseling in one metropolitan area. The subjects who had received consultation about breastfeeding were 100 breastfeeding mothers. The period of consultation was from Mar. 9, 1994 to August 23, 1994. Consultants were referred from UNICEF, hospitals, TV, newspapers or magazines. Analysis of the problem patterns resulted in 11 classifications. These were physio -anatomical factors(11 cases) , psychological factors(15 cases), breastfeeding methods(21 cases), breastfeeding intervals and frequency(19 cases) , disease in the breastfeeding mothers(13 cases), disease in the babies (12 cases), lack of support (4 cases), food and drugs while breastfeeding(5 cases), weaning(11 cases), others(27 cases). The highest frequency was for breastfeeding methods (21 cases). When the contents of the counselling were analyzed for the 100 cases, 36 problem patterns were identified. Patterns with over 10 responses were diarrhea, insufficient milk supply, sore and cracked nipples, weaning, inverted nipples and jaundice. The age of infants when mothers were telephoned was as below : 1 week(28 cases), 2 weeks(12 cases), 3-4 weeks(18 cases), 5-8 weeks(7 cases), 9 weeks-3 menths(4 cases), 4 menths-6 months(12 cases), over 6 months(2 cases), and the number of pregnant women was 12. The nursing diagnosis were classified according to problem patterns and each diagnosis was assigned an appropriate Problem Pattern The total number of nursing diagnoses was 22. When clients are referred for counselling nurses need guidelines about problems, possible causes and nursing. In this study, the example of guidelines for sore nipples is suggested. The recommendations based on the telephone counseling results are as follows : Prenatal education about the advantages of breastfeeding and breast care, and home visits after delivery for counseling related to breastfeeding. During the hospital stay, nursing intervention such as education on breastfeeding methods using slides, audio-visual tapes, pamphlets are needed as well as an initial trial of breastfeeding. Further research is indicated on the perceived lack of breast milk and on the effectiveness of nursing interventions to pro-mote breastfeeding.

Because the number of patients who require maintenance hemodialysis is increasing in number recently, angioaccess has become important to many vascular surgeons participating in the management of such patients.The authors created 269 arteriovenous fistulas[AVF] for angioaccess in 229 patients with chronic renal failure[CRF] at the Department of Thoracic and Cardiovascular Surgery in Chungnam National University Hospital during the period from August 1990 to March 1993. We analyzed the results of 260 operations for 220 patients except 9 patients who were lost during the follow up period. We performed snuffbox AVF in 171 cases, classic radiocephalic AVF in 46 cases, direct AVF at other site in 5 cases, forearm Gore-Tex AVF in 29 cases, and upper arm Gore-Tex AVF in 9 cases. We experienced 13 cases of operative failures, 11 cases of early complications, and 60 cases of late complications including obstructions during follow-up period. The 1 year, 2 year and 3 year patency rates of snuffbox AVF[Group 1], classic radiocephalic AVF[Group 2], and Gore-Tex AVF[Group 3] are like followings; 89, 84, 76% in group 1, 84, 75, 68% in group 2, and 79, 66, 55% in group 3. It showed a statistically significant difference between group 1, 2 and group 3.

During one year[1987], 110 cases of open heart surgeries were performed in the department of Thoracic and Cardiovascular Surgery, Pusan Paik Hospital, Inje Medical College. And the results were summarized as follows. 1. Among the 110 cases, there were 77 cases of congenital heart diseases and 33 cases of acquired heart diseases. Age range of the congenital patients was 8 months to 30 years with the mean age of 8 years, and acquired patients was 16 to 56 years with the mean age was 32 years. 2. The heart lung machine used for cardiopulmonary bypass was Sarns 7000, 5-head roller pump, and the number and type of oxygenators were 50 of membrane type and 60 of bubble type. For all cases GIK[glucose-insulin-potassium] solution was used as cardioplegic solution for myocardial protection during operation. 3. Among the 77 congenital anomalies, there were 67 cases of acyanotic patients[ASD: 12, VSD: 50, PS: 1, AP window: 1, Gerbode defect: 1, ECD: 2] and 10 cases of cyanotic patients[TOF: 10], and to all of which the appropriate radical operations were applied. 4. Among the 33 acquired diseases, there were one case of left atrial myxoma, one of annuloaortic ectasia, 20 of mitral valve diseases[MS: 2, MSr: 8, MR: 2, MRs: 8], 9 of double valve diseases[MRs+AR: 1, MRs+ARs: 2, MRs+TR: 1, MSr+TR: 3, MSr+ASr: 1, MSr+ARs: 1], 2 of triple valve diseases[MSr+AR+TR: 1, MSr+ASr+TR: 1]. The left atrial myxoma was removed well with right atriotomy and atrial septal approach. And to the annuloaortic ectasia, Bentall operation was applied with good result. Mitral valve replacement[MVR] was applied to 20 cases of mitral valve diseases, double valve replacement[MVR+AVR] was applied to 6 cases of double valve diseases, MVR & tricuspid annuloplasty[TVA] was applied to 3 cases of mitral 5. The number of replaced valve were 39 in 31 cases. In MVR, 5 of mechanical valves[St. Jude Medical Valve] and 26 of tissue valves[Carpentier-Edward valve] were used. In AVR, 3 of mechanical valves and 5 of tissue valves were used. 6. Postoperative complications were occurred in 23 cases, and among them 21 cases were recovered with intensive cares, but 2 cases were expired[mortality: 1.8%].

Objectives : A method of estimation using 8 populationbased cancer registries databases in Korea(KRCR DB) has been introduced as another strategy for validly estimating the national cancer incidence(NCI) in Korea. The purpose of this study was to evaluate the validity of this method with using the 7 KRCR DBs, excluding Seoul covering 21% of the total population of Korea. Methods : We designed the study method(NCSE_7) as same as the estimating method with using 8 KRCR DBs (NCSE_8) in order to ensure maximal comparability. We defined the expected number of cancer cases in each registry as the number of observed cases and then we added the weighted observed cases according to gender, age and the proportion of the population covered by each registry for the population of the seven regions and the population of all areas, with excluding these seven regions. From the expected number of total cancer incidents, the estimated NCI was calculated by dividing the expected number of cancer cases by the number of the total population. The standard error(SE) of the estimated incidence was also taken from the expected number of total cancer incidents. Results : Compared with the results of the NCSE_8, the overall age-standardized rates(ASR) in men and women became over-estimated and under-estimated, respectively. Primary sites that showed statistically significant differences were the colo-rectum, prostate, breast and thyroid. The index of death certificate only(DCO)and microscopically verified(MV)% indicating levels of data quality were decreased, especially for the brain in DCO% and kidney in the MV%. Conclusions : The database of Seoul regional cancer registry has a key role for the method to estimate the valid nationwide cancer statistics in Korea with using the population-based cancer registries databases.

Heat-transfer enhancement is seeked through modifications of fin surface. Real life plate-fin heat exchangers have complex three-dimensional geometries. Fins can have arrays of dimples and are attached to rows of penetrating tubes. To isolate the effect of surface modification, we model the real flow by a two-dimensional channel flow with a dimple on one side. The flow is analysed by solving the incompressible Navier-Stokes equation by a finite volume method on a generalized boundary-fitted coordinate. Results show a trapped vortex inside the dimple for all cases computed. Local maximum of Nusselt number occurs near the downstream end of the dimple, due to such a vortex. Location of the vortex does not change with respect to the wall temperature change, but moved downstream when Reynolds number increases. This, together with the results that in all cases vortex core is somewhat downstream of the dimple center, suggests that the mean flow above continuously feeds the kinetic energy to the recirculating flow. Heat transfer enhancement and pressure losses are studied through analysing the relevant dimensionless parameters like, Nusselt number and friction factor. In all cases computed, dimpled channel flow experiences less pressure loss than two-dimensional Poiseuille flow.

This study is about the number expressed and the number not expressed in terms of the sum of consecutive natural numbers with a difference of 2k. Since it is difficult to generalize in cases of onsecutive positive integers with a difference of 2k, the table of cases of 4, 6, 8, 10, and 12 was examined to find the normality and to prove the hypothesis through the results. Generalized guesswork through tables was made to establish and prove the hypothesis of the number of possible and impossible numbers that are to all consecutive natural numbers with a difference of 2k. Finally, it was possible to verify the possibility and impossibility of the sum of consecutive cases of 124 and 2010. It is expected to be investigated the sum of consecutive natural numbers with a difference of 2k + 1, as a future research task.
