Preoperative and postoperative TMJ symptoms were observed in mandibular prognathism of 30 patients operated on by Le Fort I osteotomy and intraoral vertical ramus osteotomy. The alterations of TMJ symptoms were investigated and the relationship between changes of TMJ symptoms and some cephalometric values including occlusal plane angle, mandibular plane angle, posteior ramal height and a degree of deviation of mandibular incisor midline to facial midline were observed. The results are as follows. The incidence of patient with TMJ symptoms before orthognathic surgery was 40% and after orthognathic surgery was 20%. The most frequetly encountered symptoms in orthognathic TMJ dysfunction patients were TMJ pain and/or clicking. After surgery 66% of the preoperative symptomatic patients reported improvement TMJ symptoms. On the orther hand 2 patient (6%) of the preoperative asymptomatic patients developed TMJ symptoms after surgery. Preoperatively, 60% of the facial asymmetric patients with mandibular prognathism had TMJ symptomas. The more severe facial asymmetry was, the higher incidence of TMJ symptoms was. The alteration of occlusal plane angle and mandibular plane angle seems to be one of the contributing factors which make to change TMJ symptoms in orthognathic patients. But its amount seems to be low significance. Increase or decrease of posterior ramal height have influence on the change of TMJ symptoms.

Performance and flow characteristics of a small forward swept propeller fan for home refrigerators are studied experimentally. An unusual discontinuity is observed in the performance curve of the fan. Mean flow fields measured with as-hole Pitot probe reveal that the flow is axial at the high flow rate and radial at the low flow rate. The flow structure changes abruptly across the discontinuity. Unsteady flow measurements with a set of hot-wire probes indicate that near the discontinuity a single-cell stall rotates at 40% speed of the fan speed, while away from the discontinuity the flow shows periodic variation corresponding to the blade passage frequency. Phase-lock averaged flow fields measured with a triple-sensor hot-wire probe show that there appears radially inward flow over the pressure side of the blade and the outward passage flow over the tip.

The bio signals essentially have different characteristics in each person. And the main purpose of automatic diagnosis algorithm based on bio signals focuses on discriminating differences of abnormal state from personal differences. In this paper, we propose automatic ECG diagnosis algorithm which discriminates normal heart beats from premature ventricular contraction using optimization of wavelet parameterization to solve that problem. The proposed algorithm optimizes wavelet parameter to let energy of signal be concentrated on specific scale band. We can reduce the personal differences and consequently highlight the differences coming from arrhythmia via this process. The proposed algorithm using ELM as a classifier show high discrimination performance between normal beat and PVC. From the experimental results on MIT-BIH arrhythmia database the performances of the proposed algorithm are 98.1% in accuracy, 93.0% in sensitivity, 96.4% in positive predictivity, and 0.8% in false positive rate. This results are similar or higher then results of existing researches in spite of small human intervention.

The Performance research about EEG-BCI algorithm in BCI-naive subjects is very important for evaluating the applicability to the public. We analyzed the result of the performance evaluation experiment about the EEG-BCI algorithm in BCI-naive subjects on three different aspects. The EEG-BCI algorithm used in this paper is composed of the common spatial pattern(CSP) and the least square linear classifier. CSP is used for obtaining the characteristic of event related desynchronization, and the least square linear classifier classifies the motor imagery EEG data of the left hand or right hand. The performance evaluation experiments about EEG-BCI algorithm is conducted for 40 men and women whose age are 23.87${\pm}$2.47. The performance evaluation about EEG-BCI algorithm in BCI-naive subjects is analyzed in terms of the accuracy, the relation between the information transfer rate and the accuracy, and the performance changes when the different types of cue were used in the training session and testing session. On the result of experiment, BCI-naive group has about 20% subjects whose accuracy exceed 0.7. And this results of the accuracy were not effected significantly by the types of cue. The Information transfer rate is in the inverse proportion to the accuracy. And the accuracy shows the severe deterioration when the motor imagery is less then 2 seconds.

Easy measurement method of orthogonal triple-sensor hot-wire anemometer is developed. Advantages of the new method is that it does not require either the exact orthogonality of the installed wires which cannot be kept during the probe manufacture and repair, nor the knowledge of the wire installation angles and the yaw and pitch coefficient of the wires. The new method introduced yaw and pitch calibration coefficients which are designed to increase monotonically with yaw and pitch angles. So the resulting calibration network is simple to recognize compared with that of the previously suggested calibration method. Verification experiments showed good accuracy and independency of the directional calibration on velocity.

선박의 대형화 및 해상사업의 기업화 등에 따라 해상운송에 있어 화물의 하역, 보관 등의 전문적인 부분을 담당하고 있는 항만하역업자, 항만터미널운영자, 창고업자 등 독립계약자의 역할은 점점 증대되어 가고 있는 추세이다. 하지만 국제해상운송은 해상운송인과 화주를 중심으로 체결한 운송계약을 중심으로 이루어져 왔으므로, 영국 보통법상의 직접계약관계의 원칙에 의해 계약당사자가 아닌 자는 계약상의 이익을 원용할 수 없다는 입장을 유지하여 왔다. 이에 대해 이를 완화하고자 하는 다양한 방안이 적용되고 있으며, '히말라야약관'도 그러한 방안중의 하나이다. 본 논문은 최근 대법원판결을 통해 우리나라 법원의 히말라야약관의 유효성 인정에 대한 내용을 재검토하고 독립계약자, 특히 항만터미널운영자의 운송계약상 제3자의 권리인정에 관한 문제에 대한 각국의 경향에 대해 살펴본다. According to the trend of a large-sized vessel and a industrial carrier, the role of the independent contractors such as transport terminal operators, stevedores and warehousemen is increasing the base of cargo distribution that include the function of storage, warehousing, loading, unloading, trimming, dunnaging and lashing. But the common law doctrine of privity of contract has been a perennial source of difficulty for litigants seeking to enforce rights and obligations arising under a bill of lading contract. When carriage contract is negotiated, the concerned parties will be aware that some portion of obligations arising from the contract will be performed by the independent contractors engaged to carry out a particular function. It is reasonable for the independent contractors to be allowed the benefit of the carrier under the contract of carriage. As a part of the alleviating measures for the liability of independent contractors has been allowed various schemes, specially including 'Himalaya Clause'. Therefore, this study performed the validity of 'Himalaya Clause' by means of a recent judicial precedent by the Supreme Court and analyzed the rights of third parties, specially transport terminal operators, under the contract of carriage.

  우리나라 해상보험 거래에서는 해상보험의 국제적 성격과 관련하여 영국의 해상보험약관을 사용하여 보험계약을 맺고, 그 약관에 있는 준거법약관을 그대로 원용하고 있다. 선박보험의 협회기간약관에서는 “이 보험은 영국의 법률 및 관습에 따른다”라는 준거법약관이 명시되어 있으나, 적하보험의 협회적하약관에서는 “이 보험증권의 규정또는 이 보험증권에 첨부된 어떠한 반대규정에도 불구하고 이 보험은 모든 보상청구에 대한 책임 및 결제에 관해서만은 영국의 법률과 관습에 따를 것을 합의한다”라는 문언을 사용하고 있어 이에 관한 해석상의 대립이 야기되었다.<BR>  영국법 준거약관에 관하여 우리나라에서는 이를 저촉법적 지정의 전부지정설과 부분 지정설로 보는 견해와 실질법적 지정으로 보는 견해로 나뉘어져 있다. 즉, 영국법 준거 약관에 의하여 보험계약의 성립, 효력과 해석 등 계약의 실질의 문제 전부에 대한 저촉법적 지정으로 보는 전부지정설, 준거약관의 문언상의 차이를 이유로 이를 보험계약에 따른 책임의 문제에 한정된 준거법으로 보고 그 외 성립 등의 문제는 다른 법(우리 법)을 따른다고 하는 부분지정설, 그리고 당해 보험계약에 대하여는 당사자가 준거법을 선택하지 않았으므로 우리 법이 당해 보험계약의 객관적 준거법이 되고, 다만 책임에 따른 문제는 영국법에 따른다는 실질법적 지정설로 나뉘어 견해가 대립하고 있다.<BR>  이와 같이 해상보험계약에서 사용되고 있는 영국법 준거약관에 관하여 견해가 나뉘어 대립하고 있으나, 이러한 영국법 준거약관이 전면적으로 유효한지 아니면 일부 범위 내에서만 유효한지에 관하여는 이를 일률적으로 해석할 수는 없으며, 계약체결당시의 당사자의 의사, 편입된 영국법 준거약관의 내용, 해상보험거래업계에 있어서의 관행, 양 당사자의 계약체결당시의 체결 교섭력의 강약 등의 여러 요소에 의하여 종합적으로 판단하여 이를 전면적으로 인정 또는 부인할 것인지 아니면 일부 범위 내에서만 그 효력을 인정할 것이지를 신중히 판단하여야 할 것으로 생각한다.   A contract of marine insurance is a contract whereby the insurer undertakes to indemnify the assured, in manner and to the extent thereby agreed, against marine losses, that is to say, the losses incident to marine adventure. And the document embodying the contract of marine insurance is called a "policy", and a contract of marine insurance is inadmissible in evidence unless it is embodied in a marine policy in accordance with Marine Insurance Act.<BR>  Marine policies, though commonly in one form, are of different kinds, and are known by different names, such as Institute Time Clause-Hulls and Institute Cargo Clauses (A), (B) and (C), which are widely used throughout the world.<BR>  One the other hand, there are the English law and practice clause in these Institute Clauses. The positioning of the English law and practice wording in the Institute Clauses means that any disputes emerging from legal cases on marine insurance contracts should be governed and construed according to English law and practice.<BR>  However, the ITC-Hulls contain the specific reference to choice of law so called English law and practice clause in a prominent position immediately after the headline describing the particular clauses : "This insurance is subject to English law and practice", while the ICC (A), (B) and (C) use recently another wording of English law and practice : "Notwithstanding anything contained herein or attached hereto to the contrary, this insurance is understood and agreed to be subject to English laws and practice only as to liability for and settlement of any and all claims".<BR>  Hence, differences of opinion can arise as to the interpretation of insurance clauses, especially ICC (A), (B) and (C), as the clause are containing the restrictive wording such as "only as to liability for and settlement of any and all claims". In respect of legal nature of English law and practice clause used in the marine insurance contracts, there are two different opinions which regarded it as "choice of proper law" and "incorporation by reference". So it is necessary to review these opinions by considering synthetically all possible materials concerning contracts.

본 논문은 Crisp Discrete Event System(CDES)에서 다룰 수 없는 특성을 가지는 의료진단이나 교통제이와 같이 애매하거나 불확실한 판단 그리고 관련성이 모호한 판단의 근거들에 의해 결정되어지는 사건들로 이루어진 Fuzzy Discrete Event System(FDES)의 모델링 방법과 그 응용에 대하여 연구하였다. 일반적인 CDES는 모델링 방법이 많이 연구되어져 왔으나, FDES는 발생되어지는 사건들의 정성적인 특성과 적용되어지는 경우가 드문 이유로 거의 연구되어져 있지 않다. 본 논문에서는 Fuzzy Timed Transition Petri Net(FTTPN)으로 FDES인 교통 시스템을 모델링하고 교통 신호제어기를 설계하였다. This paper deals with modeling method and application of Fuzzy Discrete Event System(FDES). FDES have characteristics which Crisp Discrete Event System(CDES) can't deals with and is constituted with the events that is determined by vague and uncertain judgement like biomedical or traffic control. In general, the modeling method of CDES has been studied many times, but that of FDES hasn’t been nearly studied by qualitative character and scarcity of applicated system. This paper models traffic system with FDES’s character in FTTPN and designs a traffic signal controller.
