Objective : To examine whether any correlation between tendency towards depression and tenderness at special acupuncture points exists, thus to explore the potential diagnostic property of acupuncture points. Methods : A total 31 subjects were included in this study. They filled out questionnaires about their mental [Beck Depression Inventory (BDI), Stress Response Inventory (SRI), Profile of Mood States (POMS)] and physical (fatigue due to overexertion, and food accumulation) symptoms. Identical weight around Alarm points (CV17, CV12, ST25, CV5, CV4, and LR13) and transport points (BL14, BL20, BL21, BL22, BL25, and BL27) was given using an algometer and the subjects rated their pain on an 11-point numerical rating scale. Heart rate variability (HRV) was also measured. Results : The subjects were divided into two groups, normal and depressive tendency groups with a cut-off point of nine on BDI. The depressive tendency group reported significantly higher values in SRI, POMS, and questionnaire for fatigue due to overexertion. In the pressure pain measurement, depressive tendency group had more pressure pain at CV12, left side of BL20, BL14, BL22 and both sides of BL21, BL25, BL27, significantly (each p<0.05). The data of HRV did not show significant differences between groups. Conclusions : People with a tendency towards depression may be prone to stress, negative mood, and fatigue due to overexertion. In addition, they may be more likely to develop tenderness at alarm points and transport points compared with healthy people. Further research is needed to confirm this finding.

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.
