The duration of the phases of left ventricular systole was measured from simultaneous recordings of the electrocardiogram, phonocardiogram and carotid arterial pulse tracing using a multichannel photographic system with paper speed at 100 mm per second. Observations were made in 81 male and 66 female patients with hypertension and 41 healthy males and 38 healthy females who served as controls. All hypertension patients were classified by change in funduscopic finding, EKG and grade of diastolic pressure. STI were measured in each group and analysed. The resutls were as follows: 1. The normal PEP/LVET was 0.293 in male and 0.303 in female. 2. In male & female hypertensive patients, all STI were significantly difference to that of normal control except QA2. 3. In male hypertensive patients, the degree of EKG, funduscopic change and diastolic pressure were positive relation to the increase of PEP/LVET.

PURPOSE: This study was done to explore the levels of depression experienced by adolescents, and to compare health behavior between depressed and non-depressed adolescents. METHOD: Participants were chosen by a stratified random sampling of adolescents in the second grade of a high school in P city. Levels of depression and health behavior of the students were measured using questionnaires. Data collection was done in May, 2002. Data were analyzed with descriptive statistics and logistic regression using the SPSS WIN 10.0 Program. RESULTS: The prevalence of depression (CES-D) among the students was 53.5%. In multiple logistic regression analysis, sex (OR 1.80, 95% CI 1.35-2.41), school performance, mid (OR 1.68, 95% CI 1.48-1.97) and low (OR 1.42, 95% CI 1.29-1.61), drinking (OR 1.47, 95% CI 1.09-1.98), and not eating breakfast (OR 1.74, 95% CI 1.56-1.97) were significantly higher in students in the depressed group than those in the non-depressed group. CONCLUSIONS: Based on the findings, we concluded that many adolescent experience depression and depression in adolescents is significantly related to behaviors of smoking, alcohol, no exercise, and not eating breakfast. However this study did not address causality among these variables. There, further research, such as a longitudinal study, is needed to identify causality among the variables.

PURPOSE: To evaluate morphologic characteristics of the microcalcifications on mammography that were confirmed pathologically. MATERIALS AND METHODS: Forty five cases of microcalcifications on mammography (fifteen cases of benign lesion, thirty cases of maiignancy) were retrospectively reviewed. RESULTS: The number of microcalcifications within 1 cm2 were more than 5 in 22 cases (73%) of 30 malignancy and less than 5 in 11 cases (73%) of 15 benignity. The heterogeneity of microcalcifications were seen in 26 cases of malignancy (87%) and the homogeneity of microcaicifications were 11 cases of benignity (73%). The morphologic characteristics of the microcalcifications were linear-V shape in 9 cases (30%), punctate shape in 8 cases (27%), fine stippled shape in 7 cases (23%), and round dot shape in 6 cases (20%) of malignancy and, round dot shape in 11 cases (73%), punctate shape in 2 cases (13%), and linear-V shape in 2 cases (13%) of benignity. CONCLUSION: Numerous irregular microcalcifications that are heterogenous in size and morphology were strong indicators of malignancy.

PURPOSE: The purpose of this study is to determine the detection rate of early gastric cancer and to measure the focal gastric wall thickening in computed tomography. MATERIALS AND METHODS: From November 1991 to November 1993, 19 patients (age;33--76 years, male ;female:4;5) with surgically proven early gastric cancer were examined by upper gastrointestinal series and abdominal computed tomography. Twenty lesions in these patients were included in this study. Computed tomography was performed with conventional technique using gastrografinR (17 cases) or water filling (2 cases) method in supine position. Additional scans were obtained either in right down decubitus (15 cases) or supine position (4 cases) with an ingestion of gas forming agent. We determined the detection rate of early gastric cancer at computed tomography and measured the maximum thickness of the lesion. RESULTS: The pathologic types of the early gastric cancer were type lib + IIc in 5 cases, type IIc in 6, type III in 3 and type I, I + IIc, Ila, lib, lib + III and IIc + III in one, respectively. Seventy-five percent (15 cases) of early gastric cancer was detected at upper gastrointestinal series and fifty percent (10 cases) at computed tomography. Computed tomography could detect 100% of elevated carcinomas (3/3) and 41% of depressed carcinomas (7/17). The maximum thickness of the lesion ranged from 7 mm to 11 mm (mean ;8mm). CONCLUSION: In a well-distended stomach, CT could detect focal gastric wall thickening (mostly, less than 1 cm) caused by early gastric cancer in half of the cases.

Idiopathic hypertrophic subaortic stenosis (IHSS) is characterized by asymmetric septal hypertrophy, wherein the upper portion of interventricular septum, and dynamic left ventricular outflow tract obstruction due to narrowing the subaortic area usually resulting from the middiastolic apposition of the mitral anterior leaflet against the hypertrophied septum. The goals of anesthetic management for IHSS are to prevent the development of dynamic obstruction to left ventricular ejection and to optimize ventricular filling by maintaining the heart in normal sinus rhythm. Spinal and epidural anesthesia decrease in the preload and afterload secondary to peripheral venous pooling and sympathetic blockade could act to increase the left ventricular outlet obstruction. We experienced the case of the epidural anesthesia for the dilatation and curettage of the uterus with IHSS, and there is no adverse effects of epidural anesthesia.

The arterial oxygen saturation (SaO2) changes during transportation of postanesthetic patients from operating room to recovery room were measured by pulse oximeter. Fourty-one ASA PS I premedicated children were studied. SaO2 was recorded on operating room under administration of 100% oxygen (T2), transportation one minute (T2), two minutes (T2), three minutes (T2), on arrival in the recovery room (R0), One minute (R1 ) and two minutes (R2) in the recovery room under administration of oxygen via nasal cannula or catheter through endotracheal tube. The significant difference between the extubated group (group 1) and the intubated group (group 2) was not found. The proportion of children with SaO2<95% (PaO2<75mmHg) on arrival in the recovery room with room air inhalation were 13 cases (31.7%). It is concluded that children receiving anesthesia can become hypoxemic during postanesthetic transportation with room air inhalation and in the recovery room.

We have done survival analysis of the EKG monitor(from March, 1976 to February, 1993) and anesthetic machine(from February, 1915 to February, 1993) retrospectively in operating room at Severance hospital. Thirty eight EKG monitors and twenty eight anesthetic machines were included. Also EKG monitors were divided into two groups(one group was made in foreign country and another was made in Korea) and its survival function were compared. All statistics were treated with Product-limited estimate of survival function(Kaplan and Meier, 1958) with BMDP 1L. Mean survival time(+/-S.E) of all EKG monitor was 113.61(+/-5.70) months and the EKG made in foreign country was 106.65(+/-8.22) months and made in Korea was 113.35(+/-8.97) months. But there was no statistical differences between two groups. And mean survival time of anesthetic machine was shown to be 189.45(+/-6.09) months. It is advisable to replace aging machine before malfunction and failure to protect patients from mishaps stem from equipment failure. We conclude that life cycle of equipment for proper time to replace the equipment is not underestimated to reduce the accident by aging machine failure.

BACKGROUND: Terminology is a good index of reflections in conceptional imaginations, trends and technological advances in the field of their own. The goal of this study was to compare the similarity and difference of terms in anesthesiology to evaluate the communicability between South and North Korea. These results may be particularly helpful during the next step of making glossary, academic communication and the searching of social unity at the time of reunion. METHODS: Several books and indexes written in South and North Korea and data from seminars were obtained. Multiple terms were then drawn from these data. These terms were used to make a comparison between South and North side. RESULTS: Both side does not use a Chinese character in their books and indexes, even though many terms stem from a Chinese character. North side had more terms of native language than South side. There were some different terms because of each others rules of grammar. Several terms were confusedly used in both side. In some of combined terms, words were reversed in their orders. CONCLUSIONS: We conclude that terminology using in South and North Korea in the field of anesthesiology is not so far way and both side can be capable of communication without any difficulty. But both have many areas to be filled with terms of native language to have identity.

PURPOSE: To evaluate CT findings of mucinous adenocarcinoma in the gastrointestinal tract. MATERIALS AND METHODS : CT scans of 24 gastric and five colorectal mucinous adenocarcinomas, proven by histology, were retrospectively analysed; the patients consisted of 18 men and 11 women (age range, 27-76; mean, 59). CT findings were analysed, with emphasis on : (a) tumor size and maximal wall thickness ; (b) the presence of a low attenuation area, suggestive of a mucin poll within the tumor ; (c) the presence, shape and location of calcification, and (d) correlation between primary tumor (T) staging and CT findings. RESULTS: The mean tumorsize of gastric mucinous adenocarcinoma was 8.2cm (range, 1.4 - 17cm) and the mean maximal wall thickness was2.3cm (range, 1-4.5cm). Low attenuation areas on enhanced CT were seen in 12 cases (50%). Mottled, punctate, diffuse calcifications were demonstrated in nine cases(38%), and were located in low attenuation areas in eight cases. The T staging could be determined in 22 cases. Of there, low attenuation areas were demonstrated in tencases and calcification in seven. Of those ten cases with low atteuation area T staging was T2 in two cases, T3 intwo, and T4 in six. Of the cases showing calcification, T staging was T3 in one case and T4 in six. The mean sizeof colorectal mucinous adenocarcinoma was 6cm(range, 3-13cm) and the mean maximal wall thickness was 3.6cm (range,1.5-7cm). Low attenuation area were seen in three cases. Mottled calcification within the low sttenuation was detected in one case. The T staging of three cases which showed a low attenuation area was T3 in tow cases and T4in one case. One case with calcification was T3 stage. CONCLUSION: The CT finding of mucinous adenocarcinoma inthe gastrointestinal tract was a relatively thick-walled mass containing an area of low attenuation or calcification. Although calcification is believed to be a pathognomonic finding for the specific diagnosis of mucinous adenocarcinoma, a low attenuation area may be an important CT finding because it can be detected at lower T staging and more frequently.

OBJECTIVE: The purpose of this study was to examine the relationship between attachment and behavior problems in adolescents. METHOD: A sample of 792 high school students were examined. Revised Adult Attachment Scale, Self-report Attachment Style, Youth Self-Report Child Behavior Checklist (YSR) were used to measure the attachment quality, the attachment pattern and the behavior problems respectively. RESULTS: As to the attachment quality, high score in fear of rejection, low dependability and low intimacy were related to the development of adolescent's internalizing problems. As to the attachment pattern, preoccupied and fearful with attachment experience were linked to the internalizing behavior problems of higher level as well as 'Attention problems' and 'Aggressive behavior' sub-scales of externalizing ones on YSR. CONCLUSION: High fear of rejection, low dependability and low intimacy characterise the insecure attachment. So the insecure attachment might predict the development of all internalizing behavior problems, attention problems and aggressive behavior in adolescents. Also the result suggested that the adolescents classified as Dismissing attachment may have a positive view of the self and may minimize the self reported behavior problems.
