This study was designed to identify the extent of incident shock who are in high risk of post traumatic shock stress, and analyze the related factors that affect the extent of incident shock. The subjects are 415 rescue workers from Seoul Metropolitan Fire & Disaster Headquarters, who are in high frequency of fire outbreaks and rescue mobilization. With a reliability of Cronbach's ${\alpha}$=.975, the results show invasion, avoidance, sleep disorder and emotional paralysis, dissociative symptom, hyper arousal as foremost causes respectively. Moreover, the results imply that the extent of incident shock was higher in people with more age or being married. Also, from the occupational perspective, the number of years as fire fighters, as rescue workers, mobilization and experiences at work in proportion to incident shocks has risen exponentially. It is notable that the groups who alleviate stress by consuming liquors had higher extent of incident shock. In conclusion, to deal with groups in high risk, management system and prevention care programs for incident shocks need to be introduced immediately and put into effect.

본 연구는 업종별 산업간호사의 보건관리업무의 내용과 수행정도를 측정하고 업종별 보건관리업무 수행정도를 비교 분석코저 한다. 연구방법은 산업간호사회에 등록된 산업장중 서울, 인천, 마산, 창원, 부산, 울산 지역에 있는 130개 산업장을 임의로 선정하여 산업간호사를 대상으로 설문조사하였다. 자료분석은 반도와 백분율, 업종간의 보건관리업무 내용별 수행정도는 일원분산분석과 다중검증 비교로 유의성을 검증하였다. 연구결과는 다음과 같다. 1) 업종별로 산업간호사의 업무수행에 유의한 차이를 보인 보건관리내용은 서비스업에 있어서 근로자의 건강사정에 대한 수행정도가 제조업과 기타제조업에서 보다 높게 나타났다.(F=4.23, P=.0167) 반면에 근로자의 건강진단과 계속관리, 작업환경 관리업무 수행정도는 제조업과 기타제조업에서 서비스업보다 높게 나타났다.(F=9.78, P=.0001 ; F=5.366. P=.005) 2) 업종간에 유의한 차이가 없는 보건관리내용은 산업장진단 또는 건강문제분석, 보건교육, 통상증상에 대한 투약, 기록과 보고, 건강관리실 운영 등이었으며 업무수행정도는 가끔 또는 필요시하는 정도로 나타났다. 반면에 조사, 연구 참여에 대한 수행정도는 세 업종 모두 가장 낮은 것으로 나타났다. 이러한 연구결과들은 산업장 간호사의 신규교육이나 직무교육과정운영이 업종별로 운영되어야 함을 시사해 준다고 볼 수 있으며 또한 산업간호사의 직무 중 보건 교육, 통상질환에 대한 투약, 기록 및 보고, 건강관리실운영등은 업종간에 유의한 차이가 없으나, 수행정도는 낮은것으로 나타나 이에 대한 실제적인 직무교육이 강화되어야 할 것으로 생각된다. 특히 보건교육도 업종별로 차이가 있으므로 다양한 보건교육교재의 개발이 필요하다고 생각된다.

This experiment was to evaluate lodging characteristics of 35 recommended rice varieties of Kyonggi-do at normal (110 kg N/ha) and hen (220 kg N/ha) nitrogen application rates during 1999 to 2000. At heavy N fertilization rate, varieties that were highly resistant to lodging were Obongbyeo, Daejinbyeo, Naepoongbyeo, Nonganbyeo and Ilpumbyeo. Fourteen varieties including Daeanbyeo were moderately resistant and 11 varieties including Jinbubyeo were susceptible to lodging. The lodging-related characters which showed the highest effect on lodging at lodging degree of 9 were culm length and height of center gravity, culm length at lodging degree of 5, and culm length and the third internode length at lodging degree of 3 or below. The difference in rice yield between normal and heavy nitrogen fertilization rate was within 5% in early-maturing varieties but there was great yield difference in mid- and late-maturing varieties depending on the degree of lodging. Consequently, stable rice yield could be obtained by selecting lodging-resistant varieties and lowering fertilization rate, specially in the paddy field where lodging occurrence is common.

In this paper, we propose feasible combining rules for a decoding scheme of product codes to apply finite soft decision. Since the decoding scheme of product codes are based on complex tanh calculation with infinite soft decision, it requires high decoding complexity and is hard to practically implement. Thus, simple methods to construct look-up tables for finite soft decision are derived by analyzing the operations of the scheme. Moreover, we focus on using convolutional codes, which is popular for easy application of finite soft decision, as the horizontal codes of product codes so that the proposed decoding scheme can be properly implemented. Numerical results show that the performance of the product codes with convolutional codes using 4-bit soft decision approaches to that of same codes using infinite soft decision.

The aims of this study was to examine the effect on the hand disinfection performance, the performance rate, and the satisfaction with the use of the belt-type hand sanitizers in clinical nurses. The study is a one group pre-post test quasi-experimental design. Effectiveness of using the belt-type hand sanitizers was measured with a self-reporting questionnaire. As a result, the performance of hand disinfection and the performance rate were significantly higher after using the belt-type hand sanitizers, and also, the satisfaction with the use of the belt-type hand sanitizers was significantly high. The belt-type hand sanitizer is effective method to improve both hand disinfection performance and its performance rate. Therefore, if the belt-type hand sanitizer is used in clinical practice, it may contribute to the improving the hand disinfection performance and its performance rate.

Saltwater pumping method can be used to mitigate saltwater intrusion in coastal aquifers. However, the saltwater pumping well may discharge large freshwater along with saltwater, thereby wasting precious resources. A double negative barrier was proposed: an inland well to capture freshwater and a saltwater well near the coastline to pump saltwater. A previous study anaylzed effects of double negative barriers in dispersion-dominated coastal aquifers and determined the critical pumping rate at the saltwater well which minimized the saltwater ratio at the freshwater well. However, the study resulted in 1~15% of saltwater ratios, which were too high, for example, for drinking water standards. This study analyzed cases that were considered in the previous study, but for advection-dominated cases, and found that freshwater with sufficiently low saltwater ratios could be developed at the freshwater well. In addition, for optimal groundwater management of a watershed not only the minimum saltwater ratio at the freshwater well but also the least freshwater wasted at the saltwater well must be pursued.

330 Korean adult women were examined the correlation between degree of makeup and makeup satisfaction before/after wearing masks due to COVID-19 and the moderating effect of mandatory/voluntary goal-oriented attitude toward makeup. The study found that lip makeup(p<.001) was significant variable in makeup satisfaction before COVID-19, and eyebrow makeup(0<.002) was significant after COVID-19. Although moderating effect of mandatory goal-oriented attitude, which works between degree of makeup before/after COVID-19 and makeup satisfaction was not significant, but moderating effect of voluntary goal-oriented attitude appeared to be significant before(p<.000) and after(p<.000) COVID-19. And the degree of makeup after COVID-19 was lower than before(p<.000). If one believe that makeup is for one's own satisfaction, degree of makeup can be significant effect on the makeup satisfaction, but actual behavior has shown that degree of makeup has decreased since wearing masks because of COVID-19. I hope this research will be used as marketing material for beauty and cosmetics industry.
