복합원산지제품 수용에 관한 지금까지의 많은 연구들이 다양한 시사점들을 제시해옴으로써 학문적인 기여를 해왔지만, 소비자의 구매성향에 따라 태도의 변화를 살펴본 연구는 매우 드물게 진행되어왔다. 본 연구는 기존 연구의 한계점을 보완하고자, 소비자의 구매성향을 합리적 소비성향, 브랜드 추구성향, 타인의식 소비성향으로 분류하여 고관여 복합원산지제품에 대한 수용과정이 어떻게 나타나는지를 파악해보고자 하였다. 또한 기존 연구의 측정방법을 보완하기 위하여 본 연구는 제품에 대한 복합원산지정보가 노출되기 전후의 상황을 구분함으로써, 소비자들의 수용행동을 보다 정교하게 분석하고자 하였다. 이를 위해 266명의 소비자들을 대상으로 설문조사를 실시하였으며, 구조방정식모형 분석을 통해 통계분석을 실시하였다. 연구모형의 검증결과, 소비자의 구매성향 가운데 타인의식 소비성향은 복합원산지제품의 순응과 반감에 모두 유의미한 영향을 미친다는 것을 알 수 있었다. 아울러, 복합원산지제품에 대한 반감수준은 순응수준보다 더욱 강력한 파급효과를 지닌다는 것을 확인할 수 있었다. 이상의 연구결과를 바탕으로 본 연구는 복합원산지제품 가운데 고관여제품을 판매하는 기업들을 대상으로 실무적으로 유용한 시사점을 제시하고자 하였다.

In many countries in order to manage corrosion of water treatment process, it is currently using Langelier index (LI). However, management of the Larson's ratio (LR) to compare corrosion management and LI which can be generated by the water treatment process is required. In this study, in order to ensure data LR, factors associated with the actual corrosion resistance of water treatment plant was measured. Using the measured data, the model equation can be estimated alkalinity, and using the statutory water quality data, LR and alkalinity is estimated. At comparison of the measured value and estimated value of alkalinity, it appeared in $R^2$ = 0.629, using the statutory water quality data and estimated alkalinity model, LR and alkalinity (Whole water treatment plants : 472) is estimated. Concentration of estimated alkalinity is 0.5 mg/L to 107.5 mg/L (average : 23.2 mg/L), and LR is 0.1 to 10 (average : 1.3). At tendency to corrosion of investigated LR, "No metal tendency" (>0.5) is 39 water treatment plants, 8.26 %, and "corrosion metal tendency" is 433 water treatment plants, 91.74%.

The aim of this study was to investigate the relationship between velocity and factors which could affect the velocity of mandibular movement. For this study, 30 dental students without any masticatory signs and symptoms and 90 patients with temporomandibular disorders(TMD) were selected as the control group and the patients group, respectively. After determining Angle's classification and lateral guidance pattern of occlusion, clinical examination for TMD was perfomed. Velocity and distance of mandibular movements were recorded with BioEGN, reproducibility index of lateral excursions was evaluated by Pantronic(PRI) and BioEGN (BERI) activity in masticatory and cervical muscles were measured with BioEMG, and occlusal contact time and cross-arch unbalance(Total left-right statistics, TLR) on clenching were recorded with T-scan, respectively. The results of this study were as follows : 1. Velocity in the patients was faster than that in the controls in most mandibular movements, but on wide opening and closing movement, result was reverse. 2. Velocity on closing movements were faster than that on opening movements in the control group and a similar tendency was also shown in the patients group. 3. Patients with muscle disorders showed a tendency to have the highest value of velocity of all diagnostic subgroups, while patients with degenerative joint diseases showed a tendency to have the lowest value. 4. Patients with canine guidance showed a tendency to have the highest value of velocity in three subgroups by lateral guidance pattern, while patients with group function showed a tendency to have the lowest value. 5. BERI had a positive correlation with opening velocity on lateral excursion, while TLR had a negative correlation with opening velocity on swallowing. 6. EMG activity on clenching in masticatory muscles had negative correlation with opening velocity on border movements, and on swollowing, while the activity in rest correlated positively with opening velocity on border movements. 7. There were positive correlation between the velocity and the distance in long components of mandibular trajectory.

Interannual variation and long-term trends of coastal sea surface temperature (SST) in Korea were investigated by analyzing 27 coastal SST time series from 1969 to 2004. Long-term linear increasing trend was remarkable with the rate over $0.02^{\circ}C/year$ at almost all the stations. The slope of long-term linear trend was larger at the stations along the eastern coast than in the western and southern regions. It was also noticeable that there was a common tendency of interannual variability with the period of 3-5 years at most of the stations. SST was lower in the 1970's and early 1980's while it was higher in the 1990's and early 2000's after the increase in the late 1980's. The pattern of the interannual variability of SST was similar to that of air temperature. Increasing trend of minimum SST in winter was obvious at most stations na it was larger along the eastern coast, while the linear trend of maximum SST in summer was less definite. Therefore, the decreasing tendency of annual amplitude was mainly due to the increasing tendency of SST in winter.

인위적인 수분처리에 대한 묘고생장 결과 물푸레나무는 수분처리의 영향을 크게 받지는 않았으나, 토양수분이 감소할수록 생장이 감소하였고, 들메나무는 상대적으로 토양수분이 높은 처리구$(78{\sim}90%)$에서 높은 생장을 보였다. 물푸레나무와 들메나무의 근원직경 또한 토양수분이 감소할수록 생장이 감소하는 경향을 보였다. 물질생산량의 변화는 물푸레나무의 경우 잎, 줄기, 뿌리 등 건중량이 각 처리구별로 토양내 수분이 낮아질수록 통계적으로 유의성을 보이면서 감소하는 경향을 나타냈으며, 토양수분이 $78{\sim}90%(A)$인 처리구에서는 상대적으로 $18{\sim}30%(D)$ 처리구에 비해 약 2배 이상 높은 물질 생산량을 나타 냈다. 들메나무도 각 처리구간에 차이를 보이면서 A처리구와 D의 처리구에서는 통계적으로 유의성을 보였다. 이는 토양수분이 묘목의 수세 약화 및 잎을 포함한 조직의 연화 등 생리적인 부분에 영향을 미치는 것으로 생각된다. 물푸레나무와 들메나무의 엽 특성중 SLA는 토양수분처리에 따라 통계적으로 유의성을 보이진 않았지만 처리구간 수분함량이 적을수록 감소하는 경향을 나타냈다. 그러나 LAR과 LWR의 경우에는 각 처리구간 토양내 수분함량이 적을수록 통계적으로 유의성은 나타나지 않았지만 증가하는 경향을 나타냈다.

This research was to know EMG tendency on increasing record in snatch weightlifting. In order to perform this research, we choiced 3 man national weightlifters, EMG analysis were executed on 8 major muscle(Latissimus Dorsi, Trapezius, Anterior Deltoid, Posterior Deltoid, Gastrocenemius, Vastus Medialis, Erector spinae, Abdominal). First trial record of athletics is 80% of each maximal record and increase the $5{\sim}10kg$ gradually. In this study, EMG signal scale of all muscle except posterior Deltoid muscle don't increased according to increasing the barbell weight, This showed a difference between general recognition and experiment result. In posterior Deltoid muscle, EMG signal scale increased according to increasing the barbell weight. It was assumed that EMG signal of protagonist shows possibility of linear increasing if motion have a consistency. It was assumed that In present, In order to increase one's record to $5{\sim}10kg$, Motion consistency training is more effective training method than increasing the muscle force.

Purpose: In this study the effects of a Group Counseling Integration Program for students with a tendency to internet addiction were examined. Methods: Thirty-seven students who were in a vocational high school in G city participated in a survey, which was carried out from October 12 to November 12, 2009. To test the effects of the Group Counseling Integration Program, the participants were divided into two groups, an experimental group (18) and a control group (19). The research design used in this study was a nonequivalent control group non-synchronized pre-posttest quasi-experimental research design. The research tools included a self-determination scale and an internet addiction scale. Data were analyzed using Chi-square test, t-test, and ANCOVA with the SPSS/WIN 14.0 program. Results: Significant differences were found in self-determination scores and internet addiction scores between the experimental group and the control group (F=5.99, p=.020) (t=-2.53, p=.016). Conclusion: The results indicate that Group Counseling Integration Programs are an effective nursing intervention for improving self-determination and decreasing internet addiction in students with a tendency to internet addiction.
