Operative treatment has been used in unstable ligamentous imjury of knee joint. We experienced three cases of ligamentous injury of knee that was accompained with head trauma and other organ injury. Despite of surgical candidate, we did only conservative treatment due to poor general condition and difficulty of anesthesia, The result was relatively better than we expected. We reported these cases.

.. 日本における時代劇とは歷史的な傳統を持っている映畵の形式である. 1896年日本に映畵の文化が到來してまもなく時代劇の形式は始まり, その發展を遂げて來た. そして1920年代に入ってから時代劇はもっと發展を重ね, ひとつの映畵藝術としての地位を確立するようになった. このように日本の時代劇は藝術的または形式的に完成されて行くうちに映畵の內容も大きく變わり, 色んな物語が時代劇に導入されるようになるのであった. 持にこの時期には無賴派と言われていた演劇や大衆小說の影響を受けた時代劇がはやり, 觀客の人氣をあびていたのであった. この無賴派の時代劇のなかに登場している侍の姿は初期時代の歌舞伎調の時代劇に出ているものとは違った人物であり, 獨特な人物像であったと思う. しかも彼らが侍として行動するには一定の精神に基づくものであって, それはほかならぬ「義の精神」であった. このような義の精神に基づき, 製作されている日本の時代劇は他の國では見られない映畵であり, 日本の文化や傳統, もしくは國民の歷史的情緖などを窺がうことの出來る獨創的な映畵 形式であった. この論文の目的は日本の時代劇が持っている歷史的な發展ぶりや映畵的な形式の特徵などを探究することにある.

Ionized hypocalcemia is a common finding in critically ill patients, but the relationship between ionized hypocalcemia and mortality risk in trauma patients has not been well established. The aim of this study was to assess the usefulness of initial ionized calcium (iCa) in predicting mortality in the trauma population, and evaluate its superiority over the three other triage tools: base deficit, systemic inflammatory response syndrome (SIRS) score, and triage-revised trauma score (t-RTS). A proand retrospective study was performed on 255 consecutive trauma patients admitted to our Emergency Medical Center from January to December, 2005, who underwent arterial blood gas analysis. Multivariate logistic regression analysis confirmed iCa (≤0.88 mM/L), low Glasgow coma scale score, and a large transfusion amount to be significant risk factors associated with mortality (p<0.05). The sensitivities of iCa, base deficit, SIRS score, and t-RTS were 82.9%, 76.4%, 67.1%, and 74.5%, and their specificities were 41.0%, 64.1%, 64.1%, and 87.2%, respectively. Receiver operating characteristic curve analysis determined the areas under the curves of these parameters to be 0.607±0.062, 0.736±0.056, 0.694±0.059, and 0.875 ±0.043, respectively (95% confidence interval). Although initial iCa (≤0.88 mM/L) was confirmed as a significant risk factor associated with mortality, it exhibited a poorer discriminative power for mortality prediction than other predictors, especially t-RTS.

The paper describes the process of developing and implementing In-DEBS (In-situ Demonstration of Engineered Barrier System) for analyzing thermal-hydraulic-mechanical (THM) coupled behavior characteristics of an engineered barrier system in a high-level waste disposal system. The engineered barrier system is composed of a disposal canister, buffer, and near field rock. In-DEBS is designed to analyze the THM coupled behavior due to the inflow of underground water and the heat of disposal canisters in the buffer and near field rock. Since it is difficult to assemble the buffer block while installing sensors and heaters in a disposal hole, the buffer blocks were assembled from the outside. OBPA (One-Body Pre-Assembly) assembled with buffer blocks, sensors and heater requires special transport equipment to accurately insert it into the disposal hole because the total weight is about three tones. In this study, the fully assembled buffer block was inserted by developing a crane exclusively for In-DEBS, which can be moved into an accurate position by lifting more than five tones. To analyze the THM coupled behavior of the near field rock, 4 test holes were cored around In-DEBS and a total of 40 temperature sensors and 5 pore pressure sensors were installed in the test hole. A total of 185 sensors for temperature, relative humidity, pressure and displacement sensors were installed in the In-DEBS. All sensors were connected to a multichannel measuring system that stores field data in real time. 본 논문은 고준위폐기물 처분시스템에서 공학적방벽의 열-수리-역학적(Thermal-hydraulic-mechanical) 복합거동 실증을 위한 In-DEBS (In-situ Demonstration of Engineered Barrier System) 를 개발하여 구축하는 과정에 대해 설명한다. 공학적방벽은 크게 처분용기, 완충재 그리고 근계암반으로 이루어져 있는데, In-DEBS는 완충재 및 근계암반을 대상으로 지하수 유입 및 처분용기의 발열에 의한 THM 복합거동을 분석할 수 있도록 설계되어 있다. In-DEBS 현장시험은 A-KRS의 1/2.3 규모로 설계되어 있기 때문에 처분공의 지름이 약 860 mm로 작게 굴착하였다. 따라서, 처분공 안에서 센서와 히터를 삽입하면서 완충재 블록을 조립하는 것은 힘들기 때문에 완충재 블록 일체형 설치 틀(OBPA)를 개발하여 외부에서 모두 조립하였다. 완충재블록, 센서 및 히터가 조립 완료된 일체형 설치 틀은 총 무게가 약 3톤으로 매우 무겁기 때문에, 처분공에 정확히 삽입하기 위해서는 특별한 운송기구가 필요하다. 본 연구에서는 레일을 이용하여 5톤 이상의 무게를 들어서 정확한 위치에 정치시킬 수 있는 In-DEBS 전용 크레인을 개발하여 조립완료된 완충재 블록을 삽입하였다. 근계암반의 THM 복합거동을 분석하기 위해 In-DEBS 주위로 4개의 시험공을 굴착하여 총 40개의 온도 센서와 5개의 간극수압계를 설치하였다. 또한 근계암반의 변위를 측정하기 위해 원거리에서 두 개의 경사공을 굴착하여 총 10개의 변위 센서를 삽입하였다. In-DEBS에는 공학적방벽시스템에 온도, 상대습도, 압력, 그리고 변위 센서 등 총 185개의 센서가 설치되어 있으며, 이 센서들은 모두 다채널 동시 측정이 가능한 계측시스템에 연결되어 실시간으로 현장데이터를 저장하게 된다.
