Although it has been well known that smokimg is one of the major cause of various disease and conditions, the smoking rate is still very high in Korea. A variety of smoking cessation program are provided by public organization and also by healthcare institutions. In this social enviroment, the smoker's intension and trial rates for smokimg cessation increasing, but it is also true that the succes rate is low about 30%. Therefore this study was conducted to suggest the strategies for providing the effective smoking cessation programs by exploring the factors related to recognition and behavioral intention or programs. To explain the health behavior for smoking and smoking cessation programs, the behavioral model was constructed. The model is composed of five-stages such as recognition of the program, past exprience, present smoking status, intention for smoking, and behavioral intention for cessation programs. It is results that there were very low recognition and and purchase rates for most of smoking cessation programs. Evidenced-based and effective smoking cessation progrms need to be encouraged to smokers by medical doctors, and the strategies of eucationm public realtions, and advertisement are recommended. In addition, cotinuing legal and systematic supports for smoking cessation would lower the smoking rate and ultimately ontribute to the nation;s health promotion, Recognitionm Behavioral Intention.

In this paper, a background initialization for video surveillance proposed. The proposed algorithm is that the background images are sampled n frames during ${\Delta}t$ All Sampling frames are divided by $M{\times}N$ size block every frame. Average values of pixels for same location block of the sampling frames during ${\Delta}t$t are taken. then the maximum intensity $\alpha$ and the minimun intensity $\beta$ is obtained, respecticely. The intial by $M{\times}N$ size block, then average intensity $\eta$ of pixels for the block is obtained. If the average intensity $\eta$ is out of the initial range of the background image, it is decided the moving object image, and if the average intensity $\eta$ is included in the initial range of the background image. it is decided the background image. To examine the propriety of the proposed algorithm in this paper, the accuracy and robustness evaluation results for human and car in the indoor and outdoor enviroment. the error rate of the proposed method is less than the existing methods and the extraction rate of the proposed method is better than the existing methods.

한국의 농업분야에는 여러 가지 인증제도가 존재한다. 그 예로 유기농산물 인증, GAP인증, KPGI인증, TOP푸르트/TOP라이스 인증 등이 있다. 이러한 인증제도는 소비자에게 안전하고 고품질의 농산물을 보장하기 위해 시행되었다. 하지만 각 인증제도가 명확한 목적을 보유함에도 불구하고 이러한 인증제도들이 소비자에게 관련정보를 수반하는데 성공적이지 못하다는 평가를 받고 있다. 그 이유로는 현존하는 몇몇의 인증제도가 오히려 소비자들을 혼란스럽게 하고 있다는 것이다. 그리고 각각의 인증제도를 별도로 유지하고 홍보하는 것은 더 많은 비용을 발생시킨다. 이 연구에서는 여러 인증제도를 활용하여 이러한 문제를 해결하고자 하는데 그 목적을 두고 있다.

This study was conducted to identify the family problems of the in-patients and to analize factors Influencing to the family problems. The subjects for this study were 277 family members those who were giving care for the adult patients during hospitalized in general wards at Seoul National University Hospital in Seoul. Data were collected through interviews with the questionnaire from September second to September twentieth in 1989. The instrument used for this study was the family problems scale which was developed by the researcher. Analysis of data was done by frequency, percent, mean, t-test, ANOVA, Pearson-Correlation Coefficients, and Stepwise Multiple Regression Analysis. The results of this study are summarized as follows: 1. General characteristics of the care-giver in family. The average age of care-givers was 37.9 years, and the $26.4\%$ of monthly Income of family was 310,000-500,000 won group. The $93.5\%$ of family had taken the responsibility of caring for the patients instead of hiring the care-givers, and the $12.3\%$of the care-givers complained weakning of health status during care giving for the patients. The spouse took the largest part of responsibility of the care-giving services to the patient among the family members. 2. General characteristics of the patients. The average age of patient was 47 years, and the $80.9\%$ of patient was married status. The $39\%$ of patient was father in the position of family, and the $41.5\%$ had the responsibility to support their family before hospitalization. The average hospitalization period of patient was 24.3 day and the $50.9\%$ had admission experience. 3. The factors of family problems which were faced by the family were classified into six problems. The factors of family problems were ranked as follows; the first rank problem was related to care-giving for the patients. the second problem was resulted from the patients diseases, the theirds problem was related with adaptation to the hospital enviroments, the fourth problem was related to the arisen conflicts with medical team. the fifth problem was related to the change of family function. and the sixth problem was the financial problem. 4. The relationship between the family problems and the general charateristics of the care-givers showed that the nuclear type family was higher the family problems, that the admission period of patients became longer, and that the family who had the worse condition of health status of the care givers during care giving for the patients. From the above results, it was confirmed that the family care giving for patients was faced with some problems resulted from patient's illness, relation to the medical team, adaptation to the hospital enviroment, financial problem. change of family function, and care-giving for patients.

본 논문에서는 신호감쇄 및 연집잡음(burst noise)이 존재하는 전력선 반송 채널에서 디지틀 데이터를 복조하기 위한 BPSK(Binary Phase Shift Keying) 복조기의 설계에 대하여 논한다. 이러한 BPSK 복조기의 실현에 있어서 반송파 동기호로는 소형화 및 안정화가 요구되며, 입력주파수의 변동에 대해서 낮은 위상 오차가 필요하게 된다. 이와 같은 요구조건을 만족하기 위해서 본 논문에서는 반송주파수가 10.4[kHz]이고, 전송속도가 110[bps]인 재변조방식의 BPSK 복조기를 설계 제작하였다. 설계 제작한 반송파 동기회로는 기존의 아날로그 소자로 구성되었던 승산기(multiplier) 및 지연회로를 PLL(Phase Locked Loop) IC로 대치하여 소형화 및 안정성을 확보하였으며, PLL회로 설계시에 주위온도 등을 고려하여 주파수 인입범위를 $\pm$4[kHz], 정상위상오차를 $\pm$60로 설정하였다. 기능시험 결과로부터, BPSK 복조기의 동작기능은 정상상태에서 설계조건에 만족함을 알 수 있었다.

Chonan and Asan city have been a focal point due to rapid development as the first station for Express Railroad and key cities West Coast Development Region. Gokgyo stream adjacent to the cities plays an important role as a drainage channel for an agriculture and a discharger of urban storm water. Waster quality of the stream has been deteriorating caused by pollution sources such as a untreated wastewater discharge and runoff from the watershed. In the study, we conducted 4 surveys in April, May, July, and September to understand the current state of water quality for the stream and to make it possibe to predict future water-quality variation for future development. The system runs on a personal computer under the windows enviroment and provides extensive graphic user interface(GUI) for user-friendly assessment. Using the pull-down menus provided by the GUI panel, the user is able to operate the system by pointing and clicking the icon to identify the state of water-quality at locations concerned. Furthermore, we developed an integrated watershed management system. The constructed system could be a useful tool as a decesion maker for pollution source control strategy.
