This study conducted an analysis of the changes in social work fields, focusing on the 'generational differences' after the COVID-19. As a result of the study, various opinions were presented in two areas: experience and perception of social workers and requirements of social workers. Social workers in their 20s had many requests for improvement of the current working environment and the Local Government and the Association, and those in their 4~50s had many comments about the working environment. Based on these research results, this study proposed the following practical and policy improvement measures. First, it is necessary to improve the low level of salary, work conditions and environment. Second, a safe work environment is required. Third, it is necessary to pay attention to the changed perceptions of social workers and make efforts to match them.

We looked at the background of how Western dance (Dance Sports, Social Dance) was first introduced as social dance in the past in Korean society with Confucian culture. In addition, we look into the social aspects of dance at the time, such as the spread of social dancing before the Korean War, the path through which the social dancing craze developed in the 1950s after the Korean War, and the decadent trend immediately after the Korean War, and how it transformed into a negative cultural phenomenon. We reexamined the series of events along with their social background. And now, social dance and dance sports have undergone such a significant change in perception in Korean society that they have become an indispensable element of life, to the point where the sentence is no longer unfamiliar in our country. Dancesport is an artistic indoor sport that combines elements of dance and sport. We also studied what changes have occurred in Korean society, including modern artistic elements.

Twelve patients with left ventricular-right atrial shunt (LV-RA shunt) underwent surgical correction be- tween April 1982 and March 1995. Seven patients were male and five patients were female. Age ranged from 3 to 26 years with mean age of 8.5 years. On the preoperative chest PA views, increased pulmonary vascularity was noted in 3 cases and enlargement of right atrium in 4 cases. The mean preoperative cardiothoracic ratio was 0.59. Echocardiographic studies were obtained in 9 patients and the preoperative echocardiographic diagnoses were LV-RA shunt in 2 cases, ventricular septal defect (VSD) in 6 casei, and atrial septal defect (ASD) in 1 case. The preoperative ngiographic diagnoses which were obtained in all patients were LV-RA shunt in 5 cases, VSD in 5 cases, ASD in 1 case, and VSD with ASD in 1 case. The descriptions of defect of LV-RA shunt according to intraoperative findings were supravalvular defect in 5 cases(42%), infravalvular defect in 4 cases (33%), and combined defect in 3 cases (25%). Associated anomalies of tricuspid valve in 4 cases of infravalvular defect were perforation (3 cases) and cleft (1 case). Primary closure of the septal defect was performed through the right atriotomy in all but one patient. There was no operative death. One patient underwent reoperation because of the residual interventricular shunt. All patients have been in good condition.

From March 1988 to October 1992, 201 CarboMedics cardiac valve prostheses (150 mitral, 50 aortic and 1 tricuspid) were implanted in 166 consecutive patients (mean age 38 years, male/female 66/100) by one surgical team operating on adult cardiac patients at Kyungpook University Hospital. Total follow up represen:toed 6646 patient-months (mean 40mon1hs) and follow up rate was 96%. One hundred and twenty-four patients (74.7 %) were in NYHA functional class 111 or tV preoperatively and 164 patients (98.7 %) were in class I or ll postoperatively. Hospital mortality was 4.2 % and late death was 4.2%. The actuarial survival at 78 months was 89.4%. The linearized incidence of valve related death, prosthetic valve thrombosis, anticoagulant related hemorrhage, non-structural dysfunction and reoperation was 0.72%/pt-yr, 0.18%/pt-yr, 0.18%trapt-yr, 0.18 %/pt-yr and 0. 36%/pt-yr respective y. The 78 month rates of freedom from valve related death, prosthetic valve thrombosis, anticoagulant related hemorrhage, non-structural dysfunction and reoperation were 94.9%, 99.4%, 99.4%, 98.6 % and 97.9 % respectivly. The 78 month rate of freedom from all valve related complications and deaths including hospital mortality was 90.9%. These fact suggest that the CarboMedics cardiac valve has execellent result, low incidence of valve-ie-lated complications and no structural deterioration, and long term follow up study is necessary.

The purpose of this study is to develope a parcel-based automatic simulation system of land price through the integration of urban mathematical model and GIS. The appraisal process of public land price by the local government is simple but is a great time-consuming task. Moreover, it doesn't provide any statistical analysis and spatial presentation tools. So, it is difficult for planners or administrative officials to analyze the variation of land price with spatial idea. From these, a system is developed combining two sub-systems, they are ANN(Artificial Neural Network) for the calculation of land price and GIS for visual presentation. Using Matlab application, ANN model was designed having 3-layer structure and was trained with the sample data taken from Chinju city. With the trained network, the impact of 'road', 'parks', 'height control district' and 'beauty district' on land price in 9 regions(dong) are simulated. The results of the simulation were visualized with ArcView GIS. The automatic simulation system operated through the DDE(Dynamic Data Exchange) conversation between two applications. ArcView was set as client and Matlab as server. Scripting in ArcView and customizing a window of ArcView, this system can execute the whole process of simulation by just clicking a button with mouse. As a conclusion, this system was proved to be an effective and easily controllable planning support system for the land price simulation.

Background: Video-assisted thoracic sympathicotomy plays an important role as an effective method for the treatment of axillary hyperhidrosis. People with axillary hyperhidrosis were not satisfied by the occurrence of the high rate of disabling compensatory hyperhidrosis and axillary resweating. Therefore, by comparing and assessing the clincal results according to the level and extent of sympathicotomy in axillary hyperhidrosis, we aim to determine which method will result in maximal benefits. Material and Method: Among 70 patients suffering from axillary hyperhidrosis having undergone thoracoscopic sympathicotomy from January 2001 through December 2003, 57 patients who responded to either telephone interview or questionnaire were included in the current study. The patients were divided into two groups, Group 1 (n=25): patients having undergone R3, 4, 5 sympathicotomy which consist of blocking the interganglionic neural fiber on the third, fourth, and fifth rib, Group 11 (n=32): patients having undergone R3,4 sympathicotomy which consist of blocking the interganglionic neural fiber on the third and fourth rib. The study parameters were satisfaction rate and degree of compensatory sweating. Result: There was no difference on age and sex, family history, combined hyperhidrosis, and mean follow up month between the two groups. Patients expressing satisfaction were $88.0\%$ in group and $56.3\%$ in groups 11 with statistically significant difference (p=0.02). Moderate to severe compensatory sweating were $52.0\%$ (embrassing 6 patients, disabling 7 patients) in group 1 and $62.5\%$ (embrassing 5 patients, disabling 15 patients) in groups 11 with no significance in the statistical analysis. Conclusion: R3, 4, 5 sympathicotomy was an effective means of treating axillary hyperhidrosis because of higher long term satisfaction rate.

There is a vast field of application for RFID(Radio Frequency IDentification) technology. In the case of hospitals, RFID can be used for organizing patient data. Generally, patient data has been handled with medical cards. In order to look up data about a patient, the medical card would have to be found first, within a lot of other medical cards, by hand or with a computer. This is a very inconvenient system. Also, if the card is searched by the name of the patient, fatal medical accidents may occur in cases of mix-ups. If remote RFID Tag monitoring systems are applied in this case, the patient data would be accessible in the hospital. This article will discuss the grafting of RFID systems and wireless data communicating technology. The EM4095 chip, which uses 125KHz carrier waves was used in this study. And a Bluetooth module was added for wireless data communication. The ATMEGA128 microcomputer was used to control the RFID system and wireless module. A LCD monitor was connected to the extension port for nurses to view patient data, and also, the same information was displayed on PC monitors for doctors to see. The circuit was designed to consume minimal amounts of electricity for portability, and to transmit Tag ID's in environments with a lot of noise. The article is concluded with a diagram of the whole system, and performance of each data transmitting section has been analyzed.

This study was carried out to find heavy metal contents in soil and in native plant in the regions near by zinc-mines, located at the Chilgok and Uljin Gun in Kyeongpook area. In the heavy metal contents during the to growth of native plants, Cd was contained in the order perennial > biennial > annual plant, but Cu was annual > perennial > biennial plant, and there was no difference in Zn contents. The native plants contained heavy metal highest were Osmunda japonica in Cd, Persicaria thunbergii H.G in Cu and Equisetum arvense L. in Zn. Cd was contained highest in Pteridaceae, Cu in Equisetaceae and Zn in Polygonaceae. In the heavy metal contents by the part of plant of Equisetum arvense L. and Erigeron canadensis, Cd and Zn were much contained in the order leaf > stem > root, but Cu was in the order root > leaf > stem. The average contents of Cd, Cu, Zn in soil were 1.27ppm. 12.04ppm. 64.28ppm in Chilgok, and 3.30ppm. 72.93ppm. 194.04ppm in Uljin respectively. There were positive correlations between Cd contents of heavy metals(Cd, Cu, Zn) in soil and in native plant, but not significant. It was estimated that Osmunda japonica, Pteridium aquilinum (KUHN) var and Equisetum arvense L. which most absorbed heavy metal have effect of exclusion of heavy metals near by zine-mines region.
