Loose Parts Monitoring System(LPMS) monitors loosened or detached parts and foreign parts inside the pressure boundary of a reactor coolant system (RCS). It is difficult to discriminate valid signal from LPMS alarms at full power since the signal pattern by thermal shocks and structure friction are similar to those by loose metal impacts. In addition, It is more difficult to discriminate the impact signals induced by the rod driving, sensor hard-line movement and loosened component since they have similar frequency characteristics with valid signals. This paper classifies the signal patterns by analyzing actual LPMS signal captured during nuclear power plant operation.

Resident's agreeableness anger elevation request by improvement of life environment with economy development is increasing recently. However, research about air current estimation in dwelling environment that make use of air conditioner summer and cooling room is lacking going yet much. We are going to prefer most air current pattern(speed 3 steps of swing) that offer in PAC after figure processing because user's life hysteresis and present air current pattern that is supposed and offer more agreeable environment to room resident.

We describe holographic ROM system to read bit-type data. It has optical system similar to general optical data storage system such as DVD. But because holographic data storage systems have to adopt imaging optical system, in our system bit-type data can be read out by different servos with DVD. We devised 3-hole method similar to 3- beam method for the tracking servo and used astigmatic optical system for the focusing servo. Also we developed the reference beam servo to measure movement of reference beam because especially holographic data storage systems need reference beam. The system was operated by these three servos and objective lens of NA 0.6. We obtained eye pattern from random data of 3T-2um track pitch. We also obtained another eye pattern from DVD disk by only using focusing servo PDIC in our system to verify the compatibility with DVD.

Jang Gyung Ak thought the Yang Gi was the basis of life. This is why he said doctors should emphasize on preserving Yang Gi. Before his emphasis on Yang Gi he had to study and criticize the medical concept of HaGan, DanGye and DongWon. By criticizing and overcoming their medical concept's fallacy and limitations, he made his own medicine. JangGyungAk found the importance of YangGi in the theory of changes. In the "the Book of Changes" it is said the rising movement of YangGi is expressed by recipricals and propels heaven and earth, yin and yang to change. The phenomenon of life is also a reciprocal and is lead by YangGi, and so medicine should value Yang Gi. Because the phenomenon of life is lead by this Yang Gi, it is right to base changes of diseases and organize pattern identification. The pattern identification JangGyungAk presented as two Gang six Byun sets its base on YangGi.

Skeletal Class III malocclusion is a relatively common form of malocclusion in Korea. In borderline cases where only mild skeletal discrepancy exists and if worsening of the facial profile is expected as a result of premolar extraction, mandibular full arch distalization with miniscrews is the treatment of choice. The purpose of this study was to investigate the pattern of tooth movement and evaluate the stability of mandibular full arch distalization and to identify correlation between stability and factors such as initial skeletal pattern, dental changes during treatment and alveolar bone in symphysis region using lateral cephalograms.

본 논문에서는 차세대 디스플레이로 각광받고 있는 플렉시블 디스플레이의 일환으로 전하를 갖는 입자가 전계에 의한 운동(Movement)을 기반으로 이미지를 구현하는 유리 기판 기반의 액상분말 전자종이의 패턴(Pattern)을 설계하였으며 셀 캡(Cell Gap)에 따른 구동전압의 변화를 검토하였다. 확보된 데이터를 바탕으로 플렉시블 기판을 적용한 패널을 제작할 경우 효율적인 전기적 특성을 갖는 소자의 설계조건이 제시되었다.

For the cost reduction in the fabrication of display panels, a reverse moving system was equipped to a compacted in-line wet etch/cleaning system. For the effect of the alternating movement of substrate on the wet etch process, ITO layers were etched in various moving modes of substrates and the results were compared and analyzed.

Grip strength is an objective indicator for evaluating the functional movement of upper extremities. Therapists have been using it for a long time as an excellent barometer for evaluating the therapy process, therapeutic effects and prognosis of patients with injuries in upper extremities. This study investigated the effects of extensor pattern position and elastic taping of non-dominant hand on the grip strength of dominant hand among general adults. The subjects of this study were 23 males and 7 females from physical therapy departments of 3 Universities located in Busan who agreed to participate in the experiment and the resultant data were analyzed using SPSS version 12.0. The results of the study were as follows. First, there was a significant difference between the grip strength of dominant hand when the non-dominant hand was at the neutral position and that when the non-dominant hand was at the extensor pattern position and both hands were at the maximum strength simultaneously (Bonferroni-corrected p<.001). Second, there was a significant difference between the grip strength of dominant hand when the non-dominant hand was at the neutral position and that when the elastic taping of non-dominant hand was applied (Bonferroni-corrected p<.001). Third, there was no significant difference between the grip strength of dominant hand when the non-dominant hand was at the extensor pattern position and both hands were at the maximum strength simultaneously and that when the elastic taping of non-dominant hand was applied. The irradiation effects through the extensor pattern position of non-dominant hand and application of the elastic taping to non-dominant hand showed significant results in improving the maximum grip strength of dominant hand. This finding could be suggested as the probability for the indirect treatment of the upper extremities of hemiplegia and orthopedic patients due to the long-term fixing of upper extremities.

This study simulates and compares the evacuation time and characteristics according to the living patterns on board a training ship which was launched in Dec. 2005, on the viewpoint of the various activities being possible on board a cruise ship. Based on interviews with personnels on board, 3 living patterns are set as representative living conditions; Pattern A(all personnels are positioned at their cabins), Pattern B(all personnels are positioned at lecture rooms, offices or else), Pattern C(all personnels are positioned at restaurant or cafeteria). The simulation results show that Pattern B is comparatively ideal because the evacuation time is short and there is less delay of personnels' movement on each deck. On the contrary, Pattern C is evaluated as the worst because the average evacuation time took more than 360 seconds and the bottle-neck happened at Upper deck. As a result, this study proposes the needs of various countermeasures against the fire and/or disaster, considering the various living patterns on cruiser(s) and/or passenger ship(s).
