Introduction : Laryngomicrosurgery(LMS) is frequent procedure applying to benign and early malignant larygeal disease such as vocal cord polyp, nodule and early glottic cancer. LMS has been known as safe procedure and short time consuming treatment. So few reports about complications in LMS was done. In this study, complications and problems from LMS were investigated and reported. Method : From 2000, January to 2001, December, 180 patients who were treated with LMS in Asan medical center were studied by retrograde chart review. Results : In these patients, total 9 patients(5%) were suffered from complication. 4 patients (2%) had teeth injury and 4(2%) were suffered from foreign body sensation in tongue and 1(1%) had hypoglossal nerve injury. Main mechanism of complications is thought by pressure injury by laryngoscope blade. No definite correlation between procedure and complication was observed. Conclusion : There are few neural complications with LMS such as lingual and hypoglossal nerve injury. Before operation of LMS, warning and informing of complications by mechanical stress must be done. Gentle procedure and short operation time are necessary to avoid these problems. And patients who have risk factors of oral complications such as dental disease or dental prosthesis must have dental evaluation and treatment before LMS procedure.

Following a 5.8 magnitude earthquake on September 12, 2016 in Gyeongju Province, a magnitude 5.4 earthquake occurred in the northern region of Pohang City on November 15, 2017 in South Korea. Only 7.9 % of the building structures are earthquake-resistant, according to the recent survey conducted by the government agencies in October 2017. In this paper, the linear analysis seismic performance evaluation procedure of the existing school structures presented in the revised methodology(Seismic Performance Evaluation Procedure and Rehabilitation Manual for School Facilities) was introduced. In this paper, the linear analysis evaluation procedure presented in the revised methodology was introduced and the seismic performance index of the example structure was evaluated using the linear analysis evaluation procedure. The seismic retrofit was verified by the linear and nonlinear dynamic analyses using Perform 3D. The analysis results show that the dissipated inelastic energy is concentrated on the retrofitted shear wall and the maximum inter-story drift of the stadium model structure with damping system satisfies the requirement of the current code.

The equivalent static force procedure and the response spectrum analysis method are widely used for seismic analyses of multi-story buildings. The equivalent static force procedure is one of the most simple but less accurate method in predicting possible seismic response of a structure. The response spectrum analysis method provides more accurate results while it takes much longer computational time. In the response spectrum method, dynamic response of a multi-story building is obtained by combining modal responses through a proper procedure such as SRSS or CQC method. Since all of the analysis results are expressed in absolute values, structural engineers have difficulties to combine them with the results obtained from the static analysis. Design automation is interrupted at this stage because of the difficulty in the decision of the most critical design load. Pseudo-dynamic analysis method proposed in this study provides more accurate seismic analysis results than those of the equivalent static force procedure since the dynamic characteristics of a structure is considered. And the proposed method has an advantage in combination of the analysis results due to gravity loads and seismic loads since the direction of the forces can be considered.

The thesis examines the problems for improvement of clearance procedure and shows the various ways of overcoming them. Practical implications regarding the innovation of clearance procedure are as follows. First, the basis of information for customs clearance service should be built for unifying customs clearance information and imports and exports goods. Second, Customs Service need to keep on trying continuously that customs clearance system should be inter-convertible in the inside and outside of the country. Third, reliable law and execution system should be needed to revitalize customs clearance business and the government need to take measures for new system which is suitable for our own country. Finally, mutual cooperation administration system for customer in domestic and foreign country should be made for supplying high quality clearance service. As we have reviewed above contents, the customs clearance business meet the needs of innovation with new information technique to overcome lots of problems which come by when we execute simplification of customs clearance procedure and customs inspection administration fairly. As well as, when we review a few methods in the line of our customs system, we need strongly completion of related system and arrangements in trade business and similar fields. Hereafter we hope the limitation of this study should be overcome by the process of proper inspections through subsequent studies.

갑상연골 절개술은 후두 병변이 있을 때 시행하는 수술방식으로 가장 유용한 방법이다. 그러나 후두진성대의 전반부에 수술후에 생기는 web formation은 가장 골치 아픈 속발증이다. Hayashi 씨의 hemithyrotomy는 web formation은 일으키지 않으나 후두강내의 노출이 너무 협소하여 수술조작이 매우 어렵다. Huet나 Thomson의 extended thyrotomy는 갑상연골 전하방을 제거하기 때문에 ordinary thyrotomy 보다는 훨씬 좋은 수술시야를 얻을 수 있다. 이러한 갑상연골 제거로 후두기능에는 아무런 지장을 주지 않으나 언제나 후두전반부에 laryngeal web를 남긴다. 갑상연골 부분절개술은 두 가지 원칙하에서 고안되었는데 첫째, web-formation을 없애기 위해서 후두전반부에 손상을 주지 않고 둘째, 갑상연골의 전하반부위를 수술시야의 확대목적으로 제거한다. 저자는 1976년 6월 3일 성문하 유두종을 광호식 수술방법을 처음으로 시도하여 성공시켰기에 보고한다.

Fiber Reinforced Polymer (FRP) is widely used for retrofitting concrete structures for various purposes. Especially, for the retrofitting of concrete structures subjected to blast loads, FRP is proven to be a very effective retrofitting material. However, a systematic design procedure to implement FRP for concrete structure retrofitting against blast loads does not exist currently. In addition, in case of concrete structures with inarticulate geometrical boundary conditions such as arch structures, an effective analysis technique is needed to obtain reliable results based on minimal analytical assumptions. Therefore, in this study, a systematic and efficient blast analysis procedure for FRP retrofitting design of concrete arch structure is suggested. The procedure is composed of three sequential parts of preliminary analysis, breach and debris analysis, and retrofit-material analysis. Based on the suggested procedure, blast analyses are carried out by using explicit code, LS-DYNA. The study results are discussed in detail.

The quality of track-bed fills of railways has been controlled by field measurements of density $({\gamma}_d)$ and the results of plate-load tests. The control measures are compatible with the design procedures whose design parameter is $k_{30}$ for both ordinary-speed railways and high-speed railways. However, one of fatal flaws of the design procedures that there are no simple laboratory measurement procedures for the design parameters ($k_{30}$ or, $E_{v2}$ and $E_{v2}/E_{v1}$) in design stage. A new quality control procedure, in parallel with the advent of the new design procedure, is being proposed. This procedure is based upon P-wave velocity involving consistently the evaluation of design parameters in design stage and the field measurements during construction. The Key concept of the procedure is that the target value for field compaction control is the P-wave velocity determined at OMC using modified compaction test, and direct-arrival method is used for the field measurements during construction. The procedure was verified at a test site and the p-wave velocity turned out to be an excellent control measure. The specifications for the control also include field compaction water content of OMC${\pm}$2% as well as the p-wave velocity.

Many surgical procedures have been described for the treatment of chronic lateral instability of the ankle. Tenodesis procedures using peroneus brevis tendon is traditionally common among them. Recently, the modified Brostrom anatomic procedure, that is, tightening the stretched out lateral ligaments to restore their norma] anatomy without the use of supplemental tissues and then suturing the lateral portion of the extensor retinaculum to the distal fibula over the ligament repair. has been gaining in popularity. We have reviewed 6 of 10 consecutive cases at an average of 17 months after modified Brostrom procedure. An excellent or good result was achieved in 5 cases, all of which had improved mechanical stability as measured radiographically. One case that had an unsatisfactory result was in patient who had had a previous Evans' operation. So, we believed that the modified Brostrom procedure is an excellent treating method for chronic lateral instability of the ankle.
