본 연구는 양배추에서 무테두리진딧물의 온도발육실험, 성충수명, 산자실험을 통해 매개변수를 추정하여, 약충의 온도발육모형, 무시성충의 산자모형 작성에 필요한 기본모형들을 제공하기 위해 실시하였다. 6개의 온도(10, 15, 20, 25, 30, $35{\pm}1^{\circ}C$, 16L:8D)에서 실험한 결과로 저온인 $10^{\circ}C$에서는 성공적으로 발육하지 못했다. 약충 발육기간은 온도가 증가할수록 $30^{\circ}C$까지는 감소하였고 $35^{\circ}C$에서는 다시 증가하였는데, $15^{\circ}C$에서 18.5일, $30^{\circ}C$에서 5.9일 이었다. 약충전체 직선회귀식에서 발육영점온도(DT)는 $7.9^{\circ}C$로 나타났으며, 유효적산온도(DD)는 126.3일이었다. 전기약충(1+2령), 후기약충(3+4령), 전체약충 발육률에 대한 비선형모형(Lactin 2 model)과 발육기간 분포 모형(Weibull model)을 작성하였다. 성충수명은 $15^{\circ}C$에서 비정상적으로 18.2일을 보였고, $20^{\circ}C$에서 24.4일, $30.0^{\circ}C$에서 16.4일의 범위에 있었으며, 성충 생리적 연령계산을 위한 노화율 모형작성에 이용되었다. 총 산자수는 $20^{\circ}C$에서 91.6마리로 최대값을 보였다. 본 연구를 통하여 무테두리진딧물 무시성충 산란모형 작성에 필요한 온도별 총산자수, 연령별 누적산자율, 연령별 생존율 모형 등 3개의 기본모형을 추정하였다. This study was conducted to develop temperature-driven models for a population model of turnip aphid, Lipaphis erysimi: nymphal development rate models and apterious adult's oviposition (larviparous) model. Nymphal development and the longevity and fecundity of adults were examined on cabbage at six constant temperatures (10, 15, 20, 25, 30, $35{\pm}1^{\circ}C$, 16L:8D). L. erysimi nymphs did not survive at $10^{\circ}C$. Development time of nymphs increased with increasing temperature up to $30^{\circ}C$ and thereafter slightly decreased, ranging from 18.5 d at $15^{\circ}C$ to 5.9 d at $30^{\circ}C$. The lower threshold temperature and thermal constant were estimated as $7.9^{\circ}C$ and 126.3 degree days, respectively. The nonlinear model of Lactin 2 fitted well for the relationship between the development rate and temperature of small (1+2 instar), large (3+4 instar) and total nymph (all instars). The Weibull function provided a good fit for the distribution of development times of each stage. Temperature affected the longevity and fecundity of L. erysimi. Adult longevity decreased as the temperature increased and ranged from 24.4 d at $20^{\circ}C$ to 16.4 d at $30.0^{\circ}C$ with abnormal longevity 18.2 d at $15^{\circ}C$, which was used to estimate adult aging rate model for the calculation of adult physiological age. L. erysimi showed a maximum fecundity of 91.6 eggs per female at $20^{\circ}C$. In this study, we provided three temperature-dependent components for an oviposition model of L. erysimi: total fecundity, age-specific cumulative oviposition rate, and age-specific survival rate.

The purpose of this study is to investigate the mediating effects of intrinsic job motivation on the relationship between positive psychological capital and work engagement among employees of medical tourism corporations. The results of this study showed that Intrinsic Job Motivation was significant factor between Positive Psychological Capital and Work Engagement in the medical tourism corporations.The positive psychological capital(self confidence, consisting of hope, optimism and resilience) has been conceptually and empirically demonstrated to be related to employee performance. Furthermore, Employees’ Positive Psychological Capital was positively related to extra-role intrinsic job motivation and employees’ work engagement. Therefore, This review suggest that it is of great importance to have good relationships with co-workers and fair evaluation of work performance for promotion should be considered to reduce to leave one's job.

This study is to examine the definition of marketing of Guest Data Base and to propose the effective marketing strategy in hotel. And, it is aimed at seizing the differences in recognition toward marketing of Guest Data Base among groups in hotel - duties of a post, period of service in a position, one's post of duty, forms of management. Also, it is aimed at seizing the attributes affect a profits in hotel and a guest satisfactions. Through the above, at last, this study is to propose a marketing Strategy of Hotel Data Base.

In the rainfall-runoff simulation, it is crucial problem to extract the hydrologic topographical factors that are used as the model input parameters. Those factors are drawn out from DEM(Digit a1 Elevation Model) along with GIS(Geographic Information System) techniques represent a wide range of topographical informations. GIS is employed to estimate the parameters and examine application. Also, the results from different GIS data and analysis methods are examined. In the study, spatial data are calculated using WMS(Watershed Modeling System) v.6.1, which is hydrologic analysis software coupled with GIS, and flood analysis is accomplished by HEC-1 included in WMS, and applied to Dukchon River basin. To calculate the effective rainfall CN values of NRCS are used. Clark, Snyder and NRCS methods are selected to derive unit hydrograph respectively. In addition, the characteristics of runoff responses according to the selection of GIS spatial data for NRCS CN, TIN or Grid used to extract hydrologic topographical informations. and the number of partitioning sub-basin are investigated.
