This study was managed to develope the existing numerical calculation model of near shore current and wave fields where wave and current coexist around shallow water region, and analyse their problems. Until now, nearshore current model that include longshore current and on-off shore current had shown wave characteristic based on regular wave theory. In this study, however, nearshore current characteristic was changed by directional dispersion. So the effect of directional dispersion of multidirectional irregular wave was examined numerically by the basic study of nearshore current calculation due to multidirectional wave that was driving force of pollutant material at shallow water region.

Purpose: The purpose of this study was to construct and test a structural equation model of nurses' turnover intention. Method: The participants were 716 nurses at 4 university hospitals. Data were collected by a self-report questionnaire in 2008 and analyzed using SPSS 12.0 and AMOS 4.0 Win program. Results: The fit indices of modified model were x²=285.928(p<.001),x²/df=1.958GFI=0.964, RMSEA=0.037, AGFI=0.944, NFI=0.947, NNFI=0.961, CFI=0.973, PNFI=0.658 and showed high compatibility with the empirical data. In the final model, job stress and satisfaction were found to have significant direct effects on nurses' turnover intention, while organizational culture and emotional labor were very important factors to have indirect effects on turnover intention via job stress and satisfaction. Nurses' turnover intention was accounted for 41.2% of covariance by these factors. Conclusions: Comprehensive nursing interventions for decreasing nurses' turnover intention should be focused on reducing job stress and increasing job satisfaction. Also, Nursing strategy for enhancing positive organizational culture and decreasing emotional labor would be helpful for decreasing nurses' turnover intention, too. Further studies are needed to prospectively conduct to verify these causal relationships with larger sample.

This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

Horsehair worm parasitism of mantids was investigated for two years, 2012 and 2013. The mantids were collected from forty-nine sites from August to November. Mantids collected from twenty-one sites (42.9%) including Amur silver grass plantation at Samjang-myeon in Sancheong, Gyeongnam province were parasitized by horsehair worms. C. japonensis was recorded from T. angustipennis and T. aridifolia and C. fukuii, a newly recorded species in Korea, was isolated from T. aridifolia. C. japonensis was found from T. angustipennis and T. aridifolia collected from Gyeongnam province (Jinju, Sancheong, Sacheon, Uiryeong, Hapcheon, and Goseong) and Sangju, Gyeongsbuk province. C. fukuii was isolated from T. aridifolia collected from Gunwi, Gyeongbuk province and Yangpyeong, Gyeonggi province. The C. japonensis parasitism of T. angustipennis and T. aridifolia was 27.0% and 10.7%, respectively. The number of C. japonensis in a host was from one to nine, but most was one from a host. The body length of C. japonensis showed tendency to decrease with number of parasites, but not significantly different. Horsehair worms did not affect body and abdomen length and digestive system of host. However, egg possession of host was different, that is, unparasitized T. angustipennis and T. aridifolia. had more eggs (63.7%) than parasitized ones (2.6%).

The “classroom observation” mentioned in this study refers to the efforts of teachers of young children to reflect on their teaching in the classroom and seek improvement. This study’s theme is the difficulties caused by the teachers’ reflection, resulting changes and their implications. Three researchers teaching at a specific type of educational institution were selected for the purpose of this study. Three rounds of data collection were held from September to October 12, 2017, with activities including on-site observation, video recording, the writing of journals by the teachers and interviews with them. The interviews were promptly transcribed to facilitate analysis of the transcripts. The findings of this study were: that in performing classroom observation, the teachers cited lack of time due to heavy workload, a psychological burden stemming from observing themselves and the possibility of self-exaggeration to show off. Despite these difficulties, the teachers more often reflected from a distance on what they were doing in the classroom. Close observation of the classroom of the teachers also allowed them to better understand young children. The teaching activity focused on the course, not results. Classroom observation gives teachers these opportunities as their promising start.

This study was performed to investigate the toxicity of 39 registered insecticides to the susceptibility, systemic effect, and residual effect and control effect against Pine sawyer beetle, Monochamus saltuarius. Eleven kinds of chemicals such as fenitrothion, fenthion, phenthoate, phosphamidon, dinotefuran, actamiprid, clothianidin, thiacloprid, thiamethoxam, esfenvalerate + fenitrothion, and fipronil were showed 100% insecticidal activity both in body spray and twig dipping bioassay. Among these chemicals, fenitrothion and fenthion were showed 100 % insecticidal activity when sprayed at 4000 times diluted solutions, and phenthoate, thiacloprid, thiamethoxam and fipronil were showed 100% insecticidal activity when sprayed at 2000 times diluted solution. Root systemic effect was showed 100% mortality in phosphamidon, clothianidin, thiamethoxam, and 77.7% in thiacloprid. In residual effect, fenitrothion and thiamethoxam were showed 80% mortality fifteen days after treatment (DAT), and fenthion, phosphamidon, clothianidin were showed 80% mortality ten DAT, fenitrothion, thiamethoxam, fipronil showed 100% mortality in seven DAT, thiacloprid was showed 100% mortality in three DAT. Fenthion and phenthoate were showed 100% mortality one DAT. In the control effect, 6 kinds of chemicals were showed 100% mortality one DAT and all chemicals showed 100% mortality three DAT.

Parasitism of horsehair worm in mantids were investigated for two years, from 2012 and 2013. The mantids were collected from forty-nine sites from August to November. Twenty-one sites (42.9%) of the collected mantids were parasitized by horsehair worms. C. japonensis was recorded from T. angustipennis, T. aridifolia and C. fukuii. The C. japonensis parasitism of T. angustipennis and T. aridifolia were 27.0% and 10.7%, respectively. The infested number of C. japonensis was 1-9 per host. The body length of C. japonensis showed tendency to decrease with number of parasites, but not significantly different. Horsehair worms did not affect body, abdomen length and digestive system of host. However, egg possession of host was different, unparasitized T. angustipennis and T. aridifolia had more eggs (63.7%) than parasitized ones (2.6%). C. japonensis was parasitized as immature stage in late Aug. immature and adult stage in early Sept. and only adult in late Oct. Parasitism was the highest in late Sept.
