The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

최근 국내에서는 기후변화가 용수공급에 미치는 영향을 정량적으로 평가한 사례가 많지 않으며 이와 관련된 다양한 정보를 제공하지 못하고 있는 실정이다. 따라서 미래의 안정적인 용수공급을 위해 미래 다양한 상황에 대한 분석을 통한 수자원 계획이 절실하다. 본 연구에서는 낙동강 유역을 대상으로 미래 다양한 상황을 시나리오로 구성하고 각 시나리오 경로에 대한 물 수급 전망을 통해 용수공급의 안정성을 분석하였다. 분석 결과를 통해 용수공급의 어려움을 겪을 것으로 예상되는 물 공급 취약지역을 선정하여 제시하였으며 지역별, 용도별 물 부족 시나리오를 전망하였다. 또한 용수공급시설물의 최적연계 운영을 통해 용수공급 능력 증대 효과도 분석하여 제시하였다. 향후 낙동강 유역에는 기후변화 등으로 인해 용수공급의 어려움이 예상됨에 따라 이를 완화 또는 해소하기 위해서 보다 다양한 대책 마련이 필요할 것으로 판단된다.

Hopyeongbyeo is an anther culture derived Japonica rice (Oriza sativa L.) cultivar from the cross between Hitomebore and Hwajinbyeo by the rice breeding team of Honam Agricultural Research Institute (HARI), NICS, RDA, in 2003. This cultivar has a about 126 days growth duration from transplanting to harvesting. The short and round grain shape of Hopyeongbyeo is translucent with non-glutinous endosperm. Amylose content of rice grain is about 17.8% and high palatability of cooked rice compared with Nampyeongbyeo. This cultivar shows resistant to bacterial blight pathogenes of K1. The milled rice yield of Hopyeongbyeo is about 5.13MT/ha at ordinary transplanting culture in the local adaptability test. Hopyeongbyeo would be adaptable for the southern plain area of Korea.
