  • Although total meniscectomy had been performed as a treatment of meniscal tear, many published articles reported progression of the degeneration process in the articular cartilage and development of the osteoarthritis after meniscectomy. With the increased knowledge of the biomechanical properties of the meniscus, meniscal repair has been performed increasingly to maintain the important functions of the meniscus. Outside-in, inside-out, all-inside technique have been used as meniscal repair methods. In this review, indications, operative technique, and outcomes of the all-inside meniscal repair are discussed.

  • The all inside anterior cruciate ligament reconstruction technique places an anterior ligament substitutes within two bony sockets rather than hone tunnel. This approach is accomplished through arthroscopic three portal which avoids the surgical exposure and morbidity associated with creating traditional bone tunnel. This technique has several distinct advantages when compared with the traditional ACL reconstruction through the bone tunnels. It offers the surgeon a less morbid method for ACL reconstruction that positions an ACL substitute at the anatomic attachment sites of the original ACL with two bone sockets, obviating the need for traditional bone tunnels. Graft fixation at or near the anatomic attachment points of the original ACL minimizes creep with early range of motion and reduces the abrasive 'wind-shield wipe' motion of the graft which occur with bone plugs positioned inside bone tunnels. The sagittal posterior angle to the tibial socket increases fixation strength to pullout with anterior translation force for the tibia on the femur. This technique is not graft specific and can accomodate any graft in which graft length can be customized to the intraarticular native ACL length.

  • Purpose: We introduce a technique of all inside arthroscopic capsular imbrication and lateral release used to treat patellofemoral instability. Methods: With the arthroscope in the anteromedial portal for best viewing, the arthroscopic scissor is placed through superolateral portal for proximal to distal release. The release performed 5mm to 1cm from the edge of the patella. After completion of the procedure, with the arthroscope in anterolateral portal, we inserted 5mm cannula in superolateral portal and made working portal from superomedial portal. Medial reefing was performed with all inside technique by using curved needle of the spectrum suturing system and No. 1 monofilament PDS suture is passed through the superomedial portal percutaneously and retrieved through a superolateral portal. Conclusion: Several methods for arthroscopic patella realignment have been proposed, but they have consisted primarily of arthroscopically assisted techniques using a medial incision. We believe that our procedure is preferable to arthroscopically assisted methods commonly used, in that an incision is avoided and the vastus medialis obliqqus is not violated. Our technique is minimally invasive and is easy to control the tightness of the medial patellofemoral ligament (MPFL) under direct vision.

  • Purpose: The authors introduce a new technique of arthroscopic all inside repair using anterolateral and anteromedial portals for lateral meniscus root complete radial tear in patients who underwent concurrent anterior cruciate ligament (ACL) reconstruction. Operative technique: Arthroscope is placed through anteromedial portal and suture hook ($Linvatec^{TM}$, Largo, Florida, USA) is delivered through anterolateral portal. By rotating the suture hook, it penetrates posterior horn of the torn meniscus from femoral to tibial surface for vertical orientation. PDS No. 1 ($Ethicon^{TM}$, Somerville, NJ, USA) is delivered through the suture hook, and then it is withdrawn. Both end of PDS No. 1 are taken out through the anterolateral portal. MAXON 2-0 ($Syneture^{TM}$, Norwalk, Connecticut, USA) is used to penetrates remnant of tibial attachment of the torn meniscus from tibial to femoral surface in a same manner. MAXON 2-0 is changed for PDS No. 1 from tibial to femoral surface by shuttle relay technique. PDS No. 1 is tied using SMC (Samsung Medical Center) knot. Conclusion: All inside repair is a useful technique to achieve anatomical repair and to restore the hoop tension in lateral meniscus root complete radial tear.

  • The posterior root of medial meniscus maintains normal meniscal function by circumferential hoop tension and prevents extrusion of meniscus and progression of osteoarthritis. A complete tear of posterior root of medial meniscus leads to loss of hoop tension, it is important to repair it and preserve the function of the medial meniscus. Recently, a variety of arthroscopic assisted reduction and repair techniques have been used. We create an arthroscopic all-inside suture technique using a 18 gauge spinal needle and suture anchor that is easier and more convenient compared with the previous techniques. So we report this technique with a review of current literatures.

  • Nowadays, as the environmental pollution becomes severe on the earth, the water resource which can be used practically is dried up because of the natural disaster. And so, this is the time to be necessary to have the method for saving the water resource. This study investigates the distributions of velocity and temperature by the flow analysis inside the faucet models for bathroom. Model 3 has the most uniform distribution of temperature after mixing among all models. As model 3 has the smallest velocity distribution and the biggest space to mix by comparing the other models, it is seen to have the most influence on the discharged velocity of water and save the water. As the space of various configuration inside faucet model for bathroom is made by using the result of this study, it is thought to utilize at the development of this model in which more mixing becomes and the water can be saved. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

  • The state-of-the-art techniques of storing XML data, modeled as an XML tree, are node-based in the sense that they are centered around XML node labeling and the storage unit is an XML node. In this paper, we propose a generalization of such techniques so that the storage unit is an XML subtree that consists of one or more nodes. Despite several advantages with such generalization, a major problem would be inefficiency in XPath processing where the stored subtrees are to be parsed on the fly in order for the nodes inside them to be accessed. We solve this problem, proposing a technique whereby no parsing of the subtrees involved in XPath processing is needed at all unless they contain the nodes of the final query result. We prove that the correctness of XPath processing is guaranteed with our technique. Through implementation and experiments, we also show that the overhead of our technique is acceptable.

  • The use of vibration signal for fault detection inside a machine (or its part) is not new, and a number of signal processing techniques are available at the moment. A common problem for all such techniques is the high level of background signals which often made it very difficult to distinguish the desired signals. We developed a new algorithm to detect the minute faults of rotating part based on spectral histogram analysis. The technique has subsequently been applied to the bearings and has proved to be useful.

  • The purpose of this study was to provide fundamental data for determining contents of Fundamental Nursing Practice and developing desirable bedside nursing techniques for clinical nursing areas. Subjects for this study were 86 nurses who were employees of two university hospitals located in Seoul and a district area. Data were collected by questionnaires. Items of Fundamental Nursing Practice were classified into 72 items according to the result from content analysis of 9 textbooks of Fundamental Nursing. The results are as follows : 1) Items which above 80% of respondents practiced during the school inside practice or clinical nursing practice course were axillary temperature measurement, radial pulse measurement, respiratory rate measurement, application of oral hygiene, hand-washing technique, application of hot and cold bags, intramuscular injection technique, open bed-making, soap enema method, application of nelaton catheterization and oral and nasal suction methods. 2) Above 90% of respondents replied that all items except temperature measurement and bed-making were requisite contents for Fundamental Nursing Practice. Above 10% of respondents replied oral and rectal temperature measurement and bed-making were unnecessary content. 3) Above 90% of respondents replied that operating methods of all items except isolation technique, admission and discharge procedures, and retention enema in the Fundamental Nursing Practice course and clinical situation were consistent. The main reasons that respondents did not apply methods which they learned in the Fundamental Nursing Practice course to the clinical situation were 'insufficient time', 'colleagues were using different methods', 'insufficient supply of instuments' or 'inappropriate appliances'.
