  • 본 연구에서는 위성관측 표면온도 및 해당 온도경향의 불확실성을 조사하기 위하여 북반구($30-90^{\circ}N$) 해양 지역에서 2003-2014년 4월 16-24일 기간에 세 종류의 위성관측 자료(MODIS IST, AIRS/AMSU SST, AIRS only SST)를 상호 비교하였다. AIRS/AMSU 표면온도값에 비하여 MODIS는 해빙과 해수의 경계지역에서 계통적으로 최대 1.6 K 높은 반면에, 해빙 지역에서는 2 K 낮았다. 이러한 주요 원인은 표면온도 산출알고리즘의 해표 정보(e.g., 해빙 탐지)를 위하여 MODIS는 적외 채널만을 사용하는 반면에, AIRS/AMSU는 마이크로파 및 적외 채널을 함께 사용하는 데에 있다. 미국 항공우주국(NASA's Goddard Space Flight Center; NASA/GSFC)은 AMSU-A의 노후화를 대비하기 위하여 AIRS/AMSU 알고리즘을 일부 수정하여 AIRS only 알고리즘을 개발하였다. AIRS/AMSU와 AIRS only 표면온도 사이에 평균 제곱근 오차(RMSE)값은 $30-90^{\circ}N$ 해양 지역에서 0.55 K이며, 편차(bias)는 0.13 K이었으며, 해빙/해수 경계 지역에서는 이들 차이가 더 크게 나타났다. 해빙 경계지역에서 AIRS/AMSU와 AIRS only 간의 차이가 다른 지역에 비하여 큰 이유는 AIRS only 알고리즘이 AMSU 마이크로파 자료 대신에 GCM (NOAA Global Forecast System) 온도 산출물을 사용하는 데에 있다. 세 종류의 위성관측 표면온도 자료는 $70-80^{\circ}N$ 위도대에서 유의적인 온도증가($0.23-0.28Kyr^{-1}$)를 보였다. 위성관측 표면온도들 간에 계통적인 불일치는 같은 방향(온도증가 또는 온도감소)으로 해당 온도경향 값들 간의 차이에 영향을 줄 수 있다.

  • The atmospheric infrared sounder (AIRS) sensor loaded on the Aqua satellite observes the global vertical structure of atmosphere and enables verification of the water vapor distribution over the entire area of South Korea. In this study, we performed a comparative analysis of the accuracy of the total precipitable water (TPW) provided as the AIRS level 2 standard retrieval product by Jet Propulsion Laboratory (JPL) over the South Korean area using the global positioning system (GPS) TPW data. The analysis TPW for the period of one year in 2008 showed that the accuracy of the data produced by the combination of the Advanced Microwave Sounding Unit sensor with the AIRS sensor to correct the effect of clouds (AIRS-X) was higher than that of the AIRS IR-only data (AIRS-I). The annual means of the root mean square error with reference to the GPS data were 5.2 kg/$m^2$ and 4.3 kg/$m^2$ for AIRS-I and AIRS-X, respectively. The accuracy of AIRS-X was higher in summer than in winter while measurement values of AIRS-I and AIRS-X were lower than those of GPS TPW to some extent.

  • The Family Planning Program has teen intensively implemented in Korea by the national policy since 1962. However, the desired effective results were not fully obtained by many reasons such as the shortage of qualified workers, lack of eligible women's cooperation and understanding of the importance of family planning etc., The field family planning workers is classified into two categories along the governmental personnel order; the senior field worker and the assistant field worker. The former is qualified licensed nurse and the latter same as the former of a certified nurses-aid. These family planning worker's roles are somewhat in change not only in field education, distribution of contraceptions, administrating mother's class of assistant field workers but also responsible for the senior field workers such as recording, reporting and keeping statistics. Therefor, the desired success of family planning programming in Korea depends on family planning worker's professional abilities and activities in the field. In aiming to study on professional knowledge of the above two kinds of family planning workers, the following results were obtained through a field survey with question airs done as of October, 1970 in Kyonggi-Do. 1. Working term of the family planning workers in average were less than two years. The younger the assistant Field workers were, the earlier they left job. 2. The assistant field workers selected their job in order to the superficial rather than implementing job itself. 3. Most of the workers either in the health center or in the Up-Myun had a better understanding concerning with their job ; contraceptive methods, maintenance of equipment and drug keeping, and other administrative procedures, etc., 4. They had relatively better understanding and sufficient knowledge about contraception itself and application of it's methods and side effects in detail too, but less knowledges for the care after. 5. It was hard to Find out any differences in administrative knowledge and demographic understanding. 5. It is fully agreed upon that the longer the worker have experienced with the program, the more skilful she applied. 7. The worker who had training whether pre-service or insertive are working more effectively than the untrained. 8. The fundamental demographic knowledge is recommended to obtain for the workers in Kyonggi-Do.

  • 1. Background and Purpose At the year of 2000, the society of sasang constitutional medicine acqired ${\ulcorner}$HamsanSachon DongyiSuseBowon GoboGubon${\lrcorner}$ which is presumed as the copy of ${\ulcorner}$GoboGubon${\lrcorner}$. According to Lee Sung-Su who is the great-grandson of DongMu's older brother, $[\ulcorner}$HamsanSachon DongyiSuseBowon GoboGubon${\lrcorner}$ was worked by Lee Jin-Yoon who is the grandson of DongMu's older brother and it was copied by Han Min-Gab and now is owned by Lee Sung-Su who is the son of Lee Jin-Yoon. 2. Method This paper was written in order to understand the character of the discourse on the constitutional symp toms and diseases of ${\ulcorner}$HamsanSachon DongyiSuseBowon GoboGubon${\lrcorner}$. 3. Result and Conclusion 1) Each constitutional symptoms and diseases is classed as that of exterior and interior and then classsed again as that of exterior's exterior, exterior's interior, interior's exterior and interior's interior. 2) The degree of completion is high at the chapter of Soeumin and Soyangin comparing with that of Taeeumin and Taeyangin which don't exist as the contrasted explanation. 3) Soeumin's exterior-disease is divided Taiyang(太陽) and Yangmyung(陽明)'s disease by the sweating, that's interior-disease is same to Sinchukbon(辛丑本). BaboBon already have the concept of UlKwang(鬱狂) and mangYang(亡陽), so the discourse on the constitutional symptoms and diseases of Soyangin is early establish comparing with other constitution. 4) The Cold and Hot, the constitutional symptoms and diseases, the disease theory of Soyangin can be accessible to opposite side of Soeumin's that. The disease of exterior's exterior is only explained abdominal pain and diarrhea without the concept of Mangeum(亡陰) disease, but at the time of SinchukBon the concept of Mangeum-disease is invented. 5) There is many different with SinchukBon that the classification of symptoms and diseases of Taeeumin, and not mentioned the physiology and pathlogy of the airs and fluids metabolism. 6) Healthy Energy(保命之主) show us that JungKi(正氣) is key-point of the utility of the symptoms and diseases.

  • This study was done to identify a status of home visiting project as a community health nursing system, that was the organization. personal who have age, educational background, marital status, position, experience of the home visiting in the public sectors in part of Seoul. Kyonggi, Kang-won area, It was done to provide basis data for the development of effective visiting nurses project in the health sectors, where was Health Centers in urban and rural. Branch of Health Center in rural and Health posts. The question airs were distributed 352 public health workers who working place was 118 health workers in 12 health centers in Seoul. 56 public health workers among 39 health center and other public health sectors in Kyonggi and 178 public health workers among health center and health care sectors. Data collected from October to December. 2000. The analysis by SAS system with F test, percentage and frequency. The major result were as follows. The general characteristics of the respondent show that most of them were graduates from community college and RN-BS with broadcast that they had not completed CPHN course but only two health workers have trained for the visiting nurses project. As for their grade in the position, the most of health workers have seventh level and the other CHP were above sixth level in the health care post that in the government structure. This indicates that workers do not have great authority in decision making, the most period of works in the position was one and two years indicating that they change jobs frequently. On an average their clinical experience was 4.11 years which is ideal for the total service. As for preparation of staff for home visiting workers education on visiting nurses program have to receive short term or longer term training course for strong emphasis. The analysis showed that public health visiting workers responds about active job performance that based on an area, approach of acting by districts, education and position are shown statistically significant difference between acceptance of the visiting nursing job show the same as well as visiting nurses project. Special concerns for visiting Nursing care spread came to burden, many of activity carry out main solution is covered the health problem connective support system needs of quality and quantity which out health problem. As 71.1% of visiting health service held on the poor population was under the guardianship of the law, but people who health insurance wide application under law shown a tendency to increase gradually. The general characteristics of the patients showed 56.2% of female on average of age was 66.1 years old, they have health problem was the most of 47.6% of high blood pressure and stroke, the other and as a problem that economics, which is complex welfare with out health problem. Community health care service should be combined health and social work program. The form of delivery of visiting health care given the most guide and education with counselling and support. (33.6%) Among the six category of visiting care service shown statistically significant difference and next is fundamental care, remedy care with priority.
