  • This study was carried out in order to survey the soil physico-chemical, morphology and content of saponins of 5 year-old Platycodon grandiflorum radix from different areas in Gyeongnam. Soil physical properties was showed 1.01-1.29 of bulk density of soil and soil hardness was increased with increasing soil depth, especially below the 30 cm, however it was maintained or small increased below the 40 cm. T-N and OM contents of top soil were highest at Geochang as 0.27% and 56.9 g/kg, respectively, compared to other areas. The root length was longer at Kimhea and Geochang as 33.8 and 33.7 cm, respectively, and fresh weight was heavy at Geochang as 208.5 g. The contents of saponin of P. grandiflorum radix was higher in fine root compare to main root. By region, content of saponins of P. grandiflorum radix were higher at Hapcheon than other area. Mg content was highly negatively correlated at p < 0.01 with platycodin D3, deapioplatycodin D, platycodin D, and deapioplatycodin D ($-0.499^{**}$, $-0.433^{**}$, $-0.421^{**}$, $-0.511^{**}$ respectively). These results suggest that no-fertilized Mg effected on the improvement of saponin contents in P. grandiflorum.

  • 산업체에서 사용되는 BLDC 모터 제어보드의 경우에는 대량 생산을 통하여 제작하며, 제작과정에서 발생한 불량 제어보드는 모터의 초기 기동실패와 고속회전시의 소음 및 화재 발생 등의 원인일뿐만이 아니라 이를 사용하여 응용제품을 생산하는 업체의 품질관리면에서 제어보드의 이상유무 확인이 반드시 필요하다. 일반적인 모터 제어보드의 이상 유무는 육안 및 소음에 의한 방법으로 모토의 기동실패나 고속 회전을 통한 소음등으로부터 경험에 의해 판단한다. 그러나 고속 회전시 발생되는 소음으로 모터 제어보드의 이상유무를 판단하게 되면 이상유무 판단에 필요한 시간이 길어져 대규모 생산과정에 적합하지 않을 뿐만아니라 작업자의 경험에 의존하게 됨으로써 생산성에 지장을 주게된다. 또한 검사시간을 줄이기 위하여, 저속 회전만으로 이상유무를 판단하고자 할 경우 소음정도가 약해 이상유무를 판단하기가 매우 어렵고 더욱더 숙련된 검사자를 필요로 하게 되므로 생산공정에 자동검사기의 도입이 필요하디. 본 논문은 BLDC 모터 제어기의 이상이 발생할 수 있는 경우를 고찰하고, 이러한 BLDC 모터 제어보드의 이상상태가 납땜불량 및 소자 파괴 의하여 입${\cdot}$출력이 비정상적으로 이루어 질 경우의 전류신호와 정상일 때의 전류신호를 비교분석한 후 이를 검출할 수 있는 아날로그 회로를 구현하고 실험을 통하여 검증을 하였다. 또한 이러한 BLDC모터 제어기의 검사기를 아날로그 회로로 구현할 경우의 주의점을 고찰한다.

  • Purpose: The purpose of this study was to develop the health promotion program for rural elderly through PRECEDE process. Method: The health promotion program was developed based on the preliminary diagnosis. The data collection was performed from March 10th to April 9th, 2003. The subjects were selected at Mari Myun, Geochang Gun, in Korea. The preliminary diagnosis was examined with the 115 elders. Data was analyzed by descriptive statistics and Cronbach's n test with SPSS/Win 10.0 program. Results: The health promotion program was developed based on diagnostic result using PRECEDE model. The developed program was corrected and revised with the advices from 6 experts. The final program included health responsibility(cancer prevention and early detection, hygienic, false teeth management no smoking and moderation in drink, and chronic disease prevention and management), physical activity(6 kinds of exercise), nutrition(low sodium diet calcium intake, and right eating habit), spiritual growth(spiritual demand and death preparation teaching), interpersonal relations(relationship with couple, children, grandchildren, neighborhood), and stress management(sports dance, foot massage, positive thought, and song class). Conclusion: I propose that it is necessary to identity the effect of health promotion program for rural elderly. And strategy development that can spread the health promotion program elderly is needed.

  • Purpose. This study was to suggest an appropriate understanding and attitude toward the long-term senior recuperation insurance through examining the perception of the aforementioned system from the viewpoint of the elderly population. Methods. This study was conducted on 150 participants who were aged 65 years and over in a nursing hospital, a senior citizen center and participating social welfare programs in Gyeong Gi area. Researchers visited a nursing hospital, a senior citizen center, and a senior welfare center to organize times before conducting questionnaires after interviewing individual elderly participants. Results. The results are as follows: The probability of the long-term senior recuperation insurance implementation is higher amongst the younger participants, those with average health status and where the system is recognized by neighbors, relatives and/or family. The largest group of participants show only a moderate interest in the long-term senior recuperation insurance. The attitude toward using the long-term senior recuperation insurance system in the future is undetermined due to lack of awareness. Conclusions. Although the long-term senior recuperation insurance system is for all citizens, it is important to provide the correct information to the target audience, the elderly, and raise the awareness of the system so that they have access to the necessary services.

  • Purpose: The purpose of this study was to identity the effects of a health promotion program for rural elderly on health promotion lifestyle and health status. Method: The study was a nonequivalent control group pre-post experimental design. Data collection was performed from April 12th, 2003 to August 2nd, 2003. The subjects were selected at Mari Myun Geochang Gun in Korea. 44 elders were in the experimental group and 45 elders were in the control group. The 16-week health promotion program was given to the experimental group. Data was analyzed by descriptive statistics, $x^2$-test, t-test, and ANCOV A test with SPSS/Win 10.0 program. Result: The experimental group showed higher scores of a health promotion lifestyle and perceived health status than the control group. In addition, systolic BP, heart rate, body fat and glucose of the experimental group were lower than the control group. Waist flexibility, left hand grip power, back strength and leg strength of the experimental group were higher than the control group. However, there were no significant differences in diastolic BP, total cholesterol and right hand grip power between the two groups. Conclusion: This health promotion program for rural elderly can be recommended as an effective nursing intervention in rural communities.

  • Purpose: The purpose of this study is to identity the effects of a tailored health promotion program on rural residents' self efficacy, health problems and quality of life. Method: Data were collected from May 13th, 2006 to July 29th, 2006. The subjects were selected at Gajo-myeon, Geochang-gun, Gyeonsangbuk-do, Korea. Forty three residents were included in the experimental group and 39 in the control group. The 12-week health promotion program was given to the experimental group. Data were analyzed by descriptive statistics, $\chi^2$-test, t-test and ANCOVA test with the SPSS/win 12.0 program. Result: The experimental group showed higher scores of self efficacy and quality of life than the control group, and a tower score of health problem than the control group. Conclusion: From the above results, it can be concluded that the tailored health promotion program for rural residents is an effective intervention for improving their self efficacy and quality of life and reducing their health problems. Therefore, it is necessary to spread the tailored health promotion program for residents in other rural areas in Korea.

  • Laser propagation through atmospheric disturbances is vital for applications such as laser optical communication, satellite laser ranging (SLR), laser guide stars (LGS) for adaptive optics (AO), and laser energy transmission systems. Beam degradation, including energy loss and pointing errors caused by atmospheric turbulence, requires thorough numerical analysis. This paper investigates the impact of laser beam parameters on ground-to-space laser propagation up to an altitude of 100 km using vertical atmospheric disturbance profiles from the Geochang SLR Observatory in South Korea. The analysis is confined to 100 km since sodium LGS forms at this altitude, and beyond this point, beam propagation can be considered free space due to the absence of optical disturbances. Focusing on a 100-watt class laser, this study examines parameters such as laser wavelengths, beam size (diameter), beam jitter, and beam quality (M2). Findings reveal that jitter, with an influence exceeding 70%, is the most critical parameter for long-exposure radius and pointing error. Conversely, M2, with an influence over 45%, is most significant for short-exposure radius and scintillation.
