이제까지 슬관절 파열의 진단에는 관절조영술이나 관절경검사가 주로 이용되어 왔다. 저자들은 골스캔을 이응해서 슬관절 반월판 파열의 진단을 시도하였다. 슬관절 조영술이나 관절경검사로 확진된 반월판 파열 환자 7명에 대해 $^{99m}Tc-MDP$와 $^{99m}Tc-PYP$, 20mCi를 주사해서 동적, 정적영상 및 바늘구명 조준기를 이용한 영상을 얻었다. 그 소견은 1) 동적영상에서 반월판 손상부위의 혈류가 국소적으로 증가되었고, 2) 정적영상 및 바늘구멍 조준기를 이용한 영상에서 손상 부위의 경골과(tibial plateau)를 따라 특징적으로 얇은판 모양의 방사능 집적을 관찰할 수 있었다. 슬관절의 골신티그래피는 반월판 파열의 유용한 진단 방법으로 사료된다.

Electrical discharge machining is the method of using thermal energy by electrical discharge. Generally, if the material of workpiece has conductivity even though it is very hard material and complicated shape which are difficult to cut such as quenching steel, cemented carbide, diamond and conductive ceramics, the EDM is favorable one of possible machining processes. But, the process is necessarily required of finish cut and heat treatment because of slow cutting speed, no mirror surface, brittleness and crack due to the residual stress for manufactured goods.

Cognitive radio has been recently proposed to dynamically access unused-spectrum. The CR users can share the same frequency band with the primary user without interference to each other. Usually each CR user needs to determine spectrum availability by itself depending only on its local observations. But uncertainty communication environment effects can be mitigated so that the detection probability is improved in a heavily shadowed environment. Soft detection is a primary user detection method of cooperative cognitive radio networks. In our research, we will improve system detection probability by using optimal cooperative node selection algorithm. New algorithm can find optimal number of cooperative sensing nodes for cooperative soft detection by using maximum ratio combining (MRC) method. Through analysis, proposed cooperative node selection algorithm can select optimal node for cooperative sensing according to the system requirement and improve the system detection probability.

When conscious and unconscious exploring information of space-visitors which is contained in the information acquired in the process of seeing any space is analyzed, it can be found what those visitors pick up as factors in the space for its selection as visual information in order to put it into action. This study, with the object of the space reproduced in three dimensions from the cafe which was visited for conversation, has analyzed the process of acquiring space-information by sex to find out the features of scanning path, findings of which are the followings. First, the rate of scanning type of males was "Combination (50.5%)- Circulation (31.0%) and that of females "Horizontal (32.5%) - Combination (32.1%)", which shows that there was a big difference by sex in the scanning path which took place in the process of observing any space. Second, when the features of continuous observation frequency by sex is looked into, the trends of increased "horizontal" scanning and decreased "Combination" scanning of both showed the same as the frequency of continuous observations increased, while in case of "Circulation" scanning, that of females was found to decrease but that of males showed the aspect of confusion. Third, the 'Combination' scanning of males was found strong at the short observation time with three times of continuous observation frequency defined as "Attention Concentration" while the distinct feature was seen that the scanning type was dispersed to "combination-circulation" as the frequency of continuous observation increased. Females start the information acquirement with "combination-circulation" but in the process of visual appreciation they showed a strong "Horizontal" These scanning features can be defined as those by sex for acquiring space information and therefore are very significant because they are fundamental studies which will enable any customized space-design by sex.

Bisphosphonate가 백서 발치와의 치유과정에 미치는 영향에 대해 관찰하고자 생후 2개월 된 Sprague-Dawley계의 백서 18마리를 사용하여, 실험군과 대조군 모두 발치를 용이하게 하고 외상을 최소화 하기 위해 발치 전에 하루 ${\beta}-Aminoproprionitrile(APN)$ 0.2g/㎏을 5일간 투여한 후 발치하고, 감염방지를 위해 매일 1.5㎎/㎏ ampicillin을 3일 동안 근육주사 하였다. 실험군에서는 Biosphosphonate 1㎎/㎏을, 대조군에서는 vehicle(0.9%saline)을 1주에 3회씩 2주 동안 피하 주사하였으며, 각 군은 발치 후 1주, 2주, 4주 간격으로 3마리씩 희생시켜 H&E 염색에 의한 조직학적인 관찰, TRAP 염색에 의한 파골 세포의 활성, 경도 측정기에 의한 경도 측정을 통해 다음과 같은 결과를 얻었다. 1. 각 주간의 전반적인 치유양상은 시간이 경과함에 따라 실험군과 대조군 공히 유사한 치조골 회복 양상을 보였다. 2. 파골 세포의 활성은 1주, 4주 군에서는 실험군과 대조군에서 유사한 양상을 나타내었으나, 2주 군에서는 실험군에서 대조군에 비해 감소된 파골 세포 활성 양상을 관찰 할 수 있었다. 3. 경도측정에서는 모든 군에서 대조군에 비해 실험군에서 유의성 있는 증가 양상을 보였으며, 시간경과에 따른 경도의 차이에서는 1주군과 4주군 간에서 대조군에 비해 실험군에서 통계학적으로 유의성 있는 증가 양상을 보였다.(p<0.05) 이상의 연구를 통해 Bisphosphonate가 백서 발치와의 치유과정과 파골 세포의 활성에 영향을 미치며, 치유된 발치와의 경도를 증가시키는 것으로 나타났다.

A laser speckle is a random pattern that has a granular appearance produced by reflected light when a coherent laser illuminates an irregular course surface. Laser speckle system has many advantages. It can detect some animals functional parts. Moreover, it relatively consists of simple and in-expensive system. It is very important that detecting micro-vessels through image processed image. Current study is to improve image quality through variable image processing method. But this paper made laser speckle endoscope for miniaturization and commercialization laser speckle system. We had endoscope test through goldfish's tail. We will compare the processed speckle image and halogen image.

We report the case of a 21-year-old man with acute septic arthritis of the knee after meniscal allograft transplantation, which was successfully treated with repeated arthroscopic debridement and irrigations. Our procedures included arthroscopic debridement and irrigation with 10L normal saline, repeated arthroscopic irrigations (5 times), and intravenous antibiotics. Our decision to repeat the debridement was based on clinical and laboratory results. The significance of this case is that early aggressive arthroscopic debridement and repeated irrigations as part of a treatment protocol of acute septic arthritis after meniscal allograft transplantation can be an effective treatment option in selected cases.

In the CR-enabled MANET, routing paths can be easily destroyed due to node mobility and channel unavailability (due to the emergence of the PU of a channel), resulting in significant overhead to maintain/recover the routing path. In this paper, network caching is actively used for route maintenance, taking into account the properties of the CR. In the proposed scheme, even if a node detects that a path becomes unavailable, it does not generate control messages to establish an alternative path. Instead, the node stores the packets in its local cache and 1) waits for a certain amount of time for the PU to disappear; 2) waits for a little longer while overhearing messages from other flow; 3) after that, the node applies local route recovery process or delay tolerant forwarding strategy. According to the simulation study using the OPNET simulator, it is shown that the proposed scheme successfully reduces the amount of control messages for path recovery and the service latency for the time-sensitive traffic by 13.8% and 45.4%, respectively, compared to the existing scheme. Nevertheless, the delivery ratio of the time-insensitive traffic is improved 14.5% in the proposed scheme.

Physicochemical properties of potato starches with degree of substitution of 0-0.2645 hydroxypropylated with propylene oxide were examined. Hydorxypropyl group content of the starch was proportional to propylene oxide concentration. Water binding capacity increased but pH decreased with the increase of degree of substitution. Blue value and iodine absorption property decreased with the increase of hydroxypropylation. Differential scanning calorimeter showed that hydroxypropylation lowered the gelatinization temperature of the starch. Relative crystallinity in X-ray diffraction patterns decreased and starch granule observed by scanning electron microscopy was destroyed by hydroxypropylation. This result implied that high level hydroxypropylation affected the crystal region as well as amorphous region of starch.
