Purpose: For the reconstruction of the ankle joint as well as the soft tissue defect in the distal lower leg, a free flap or a local flap has been used, and because of the condition of patients, if a complex microvascular surgery under general anesthesia could not be performed, it could be reconstructed by using the distally based lateral supramalleolar fascio-cutaneous island flap using the perforating branch of the peroneal artery in the ankle area. Methods: The study subjects were 4 male patients between 53 years and 73 years of age. 2 cases were tissue defect in the medial malleolus area due to systemic diseases such as gouty arthritis accompanied traffic accident, diabetes mellitus foot, atherosclerotic obliterans, etc., 1 case was the defect in the pretibia area, and 1 case was the defect underneath the lateral malleolus, which was reconstructed by the distally based lateral supramalleolar fascio-cutaneous island flap. The donor area was the skin harvested from the groin, and the full thickness skin graft was performed. The size of the flap varied from $4{\times}3cm$ to $9{\times}6cm$. As the flap border, the medial side was to the tibialis anterior tendon, the lateral side was to the fibula crest, and the proximal area was less than the fibula size. Results: The consequence is that, in total 4 cases, the congestion in the flap began from 12 hours after the surgery, and the progression of congestion was ceased on the 5th day after the surgery, and finally epidermal bulla and sloughing, partial necrosis was developed. After the end of necrosis, the defect area was reconstructed successfully by the second full thickness skin graft. Conclusions: Although the distally based lateral supramalleolar fascio-cutaneous island flap has the shortcoming of requiring the second skin graft, it has the advantages that it does not require a long complex microsurgery, the flap itself is thin, it is similar to the color of the skin in the recipient area, and it does not leave a big scar in the donor area. Therefore, it is thought that for the cases who could not undergo a long complex surgery due to systemic diseases or the cases of patients whose condition of the recipient area is not suitable for microsurgery, the lateral supramalleolar fascio-cutaneous island flap is very useful for the reconstruction of the distal lower leg and the ankle joint area.

The purpose of this study is to diagnose actual condition of preference of hair-styling, hair-styling techniques, management, grasping a consumer's consciousness, etc with women living in a city. The survey was gotten to a feminine customer who visited the ten of beauty-shops in shopping center. And statistical data about the actual condition of hair-styling preference realities, hair-styling method and style management was entered into the SPSS statistics analysis system. In brief, be as follows by the results of study. There showed significant difference that noted in hair-style information and basis alternative a beauty salon, there were able to know people whose age is from 20's to 40's got mainly an influence of public media very much and from 40's to 50's got mainly an influence of people around them. Basis alternative of a beauty salon showed significant difference to follow age categories. It appeared that introducing from people around them have a effect on the 20's and 30's, and 40's got an influence of convenience of traffic, and 50's got mainly the shortest distance. In an attitude toward a hair style, especially toward hair cut, a case to do hair cut was most a lot of in own selections, and its result was independent of age categories. The reason that wants to give a chance was most a lot of thinking without an age. Preference length of hair cut showed a significant difference according to age. In permanent section, own selections appeared most regardless of age. And in the permanent motive, also, to have a change appeared most regardless of age. And people had a preference natural to role up to setting regardless of age in permanent wave. In hair color section, women whose age is 20's, 30's, 40's had a motive for a change, on the other hand, 50's and their senior had a motive for a gray hair. Women of all over the age almost knew a fashion color, and they had a preference brown color. In a preference way along a hair color kind, there was a significant difference according to age, also. 20's and 30's did mainly 'semi-permanent coating' and 40's and 50's did mainly 'permanent hair color'. In a attitude about a hair-style management, the more age is young, the more a period is long term. And the more age is old, the more the outlay for price of cut is expensive. But, on the contrary, permanent price showed that the more age is young, the more the outlay for price of permanent is expensive. In hair color, the more age is old, the more a period is short and the more price is low.

네트워크 관리는 다양한 네트워크 장비들을 적절하게 구성하고 운용하는 것이다. 대부분의 네트워크 관리 시스템은 장치구성 관리자, 성능관리자, 장애 관리자 등과 같은 기본부분으로 구성된다. 최근 광역의 개방형 인터넷의 등장으로 네트워크의 규모가 커지고 복잡해짐에 따라 다양한 네트워크 장비 및 호스트들에 대한 관리 역시 복잡해지고 중요하게 되었다. SNMP기반의 네트워크에서 다양한 종류의 네트워크 장비들을 관리하기 위한 네트워크 관리 프로그램을 개발하기 위해서는 많은 비용과 시간이 소모된다. 따라서 네트워크 환경을 확장하고 다양한 네트워크 장비들을 효율적으로 제어하기 위해서 이 논문에서는 트리거 기반의 네트워크 관리프로그램 자동생성기를 가지는 능동적인 네트워크 관리시스템을 제안한다. 트리거는 이벤트 컨디션 액션의 능동규칙으로 표현되어지며 네트워크 환경에 상태 변화가 생기는 경우 이를 감지하는 역할을 한다. 제안된 능동적인 네트워크 관리 시스템은 네트워크 엘리먼트들을 추가하거나 변경하는 경우 트리거 규칙이 활성화되고 네트워크관리시스템의 구성요소들이 상호작용하여 SNMP라이브러리에서 제공되는 정보들을 이용하여 새로운 네트워크 장비 관리 프로그램을 자동으로 생성한다. 능동적인 네트워크 관리 시스템은 자동생성된 네트워크 관리 프로그램을 이용하여 SNMP 네트워크 구성을 효율적으로 확장하는 것이 용이하다. 또한 ANMS 는 네트워크 관리프로그램의 개발기간 단축과 비용절감의 효과를 가져온다는 것을 실험을 통해서 확인 할 수 있었다.

PURPOSES : This study presents the noise level and frequency characteristics investigated in the national highways with the consideration of various measuring conditions and/or methods. METHODS : The noise levels on the asphalt concrete pavement(ACP) and the jointed plain concrete pavement(JPCP) of the national highway were measured and analysed with respect to three variables, i.e., pavement type, surface condition, and measurement distance. The PASS-By method is utilized for the noise measurement and then using CPB spectrum analysis method with 1/3 octave bandwidth, the noise levels and frequency characteristics were calculated for two-second periods before and after the peak noise. RESULTS : Depending on the pavement type, the noise level was changed as the average noise levels are 73.3dB(A) and 78.3dB(A) for ACP and JPCP, respectively. With respect to the effect of surface condition, the average noise levels for crack H(high), M(medium), and L (low) sections are 77.4dB(A), 77.4dB(A), and 78.1dB(A), respectively. Regarding the measurement distance, 1.2meter difference in measuring location reduces 1.6dB(A) of noise level; the average noise levels at 5.3m and 7.5m from the centerline of outer lane are 72.8dB(A) and 71.2dB(A), respectively. It should be noted that the noise levels are slightly different as a function of vehicle speed and type. However, the overall trends for each case was similar. It was found that the domain frequency bands for ACP and JPCP were 400Hz~2000Hz and 500Hz~2000Hz, respectively. CONCLUSIONS : Based on the analysis with the measured noise date from national highway, it was concluded that the noise level and frequency band vary depending on the various conditions. It was also found that some variables significantly affect the noise level while others do not. With further systematic investigation, the comprehensive noise characteristics on the national highway can be achieved. Using such database, it is possible to develop the fundamental noise reduction technology.

When the natural villages in Jeju province are incorporated into the district of city planning, they are considered to be a small-scale residential districts. Therefore, a garden city should be planned that considers the characteristics of the villages to implement an appropriate street system, to use the area effectively, and to harmonize the villages with the surrounding communities. There have been an especially large number of problems with the street system in the city of Seogwipo, which was notified as the area of natural settlement. This study analyzes the problems inherent in street planning and the present condition of roads whose construction has been postponed for a long time due to several problems including an inappropriately planned street system. Based on the research of various documents, a practical street system has been investigated. Most of the residents in natural settlement units demand use of the continued the existing roads as well as the implementation of an effective street system. They ask for street planning under which the involved construction would take only a short period of time and would result in only minimal damage to their existing properties. Therefore, the street system should be planned so as to preserve the nature-friendly features of natural settlements, their surroundings and tourism resources. Even after streets hwve been planned and their completion you has been established, the plan should be continuously evaluated, analyzed and compared with other alternatives. The street plan should continuously incorporate improvement measures which would satisfy various aspects of the street system including land use, traffic demand, and future population demands. Both the amount of money to be invested and economical efficiency should be considered for street planning since the street system has a great impact on many industries. Unnecessary costs related to excessive road construction should be avoided. The street network plan should also include the complete evaluation of the natural topography as well as the surrounding. Considering these views, the data concerning the current condition of the city and the related investigation play an important role in establishing a street plan. However, the investigation of future construction plans by the city is as of yet at a very early stage. Therefore, there is an urgent need for the investigational study of the current city development plans. The street system for the natural settlement area should be established only after the thorough investigation of all aspects of street planning. In addition, the plan should be flexible enough to consider the characteristics of Jeju.

밀집이 심한 도시는 불투수 면적이 많아 흘러나온 빗물이 빠르게 도로를 타고 한쪽으로 모이게 된다. 이는 도로에 설치된 빗물받이로 차집이 되지 못한 많은 노면 유출수로 인해 측구에서의 흐름 폭이 넓어져 정체 노면수를 증가시켜 교통체증과 미끄러움으로 인한 사고를 유발한다. 이에 본 연구에서는 차집유량 산정식을 제시하기 위해서 간선도로와 고속도로의 최대 종경사를 반영하여 2~10 %의 도로 조건을 반영하였고, 측구 횡경사는 일반도로 횡경사인 2 %를 선정하였다. 도로 차선조건은 중앙차선과 보도를 경계를 2, 3, 4 차선을 선정하였으며, 실험유량은 설계 빈도 상황을 고려하여 실제 도로 조건의 5년, 10년, 20년, 30년의 설계빈도 유수유출량을 실험유량으로 환산한 결과 1.36 l/s~3.96 l/s의 유량을 10개로 나누어 수리실험을 진행하였다. 또한, 측구로 들어오는 유입유속과, 흐름 폭을 고려한 식을 제시하였다. 실험 결과 종경사 증가에 따라 흐름 폭은 증가하고, 차집율은 감소하는 경향을 보였다. 이에 본 연구에서는 IBM SPSS Statistics 24 프로그램으로 회귀분석하여 설계빈도에 따른 우수 유출량, 도로의 종경사를 반영한 흐름 폭과 유입유속의 빗물받이 차집유량 산정식을 도출하였다. 산정된 도출식은 도로에서의 빗물받이 설계에 기초자료로 활용될 것으로 판단된다.
