The purpose of this paper was evaluate the specificity of maximal oxygen uptake and anaerobic threshold which is indicator of cardio- respiratory function during incremental load exercise using treadmill, also. Twenty of elite middle and long distance runners participated as subjects of this research. By measurement the specificity of cardio-fulmonary function and blood component in middle and long distance runners, the conclusion and results which is obtained is as follows: 1.Maximal oxygen uptake of absolute and relative value during maximal exercise load in middle and long distance runners was display 4.23±0.421/min & 71.2/㎖/kg/min, respectively, also, maximal ventilation and maximal heart rate was expressed 146± 18.861/min & 192.25 ± 7.61beats/min, respectively. 2.Oxygen uptake and relative percentage of maximal oxygen uptake in the anaerobic threshold levels of middle and long distance runners was shown 3.55± 0.491/min(46.54㎖/kg/min) 72.81±8.86%, respectively and ventilation, heart rate and relative percentage of maximal heart rate was expressed 95.09 ± 16.951/min, 176.54 ± 9.79beats/min and 91.62 ±3.90%, respectively. 3.Concentration of plasma lactate(t-value:-3.65, p<0.003), glucose (t-value:-4.52, p<0.02) In blood component of middle and long distance runners was display the significantly difference between pre and post value after maximal incremental exercise load.

Soft tissue expansion is widely used technique in oral & maxillofacial reconstruction and provide new method of reconstruction in posttraumatic alopecia, post burn, wide scar, congenital deformity, benign tumor, tattoo, etc. Expanded tissue flaps have the advantage of increased vascularity, proximity to the defect, and similarity of color and texture. They also preclude the need to advance flaps from distant sites. Tissue expansion can be used to form a well vascularized cavity to accomodate and nourish bone grafts. The following report describes the uses of tissue expanders by allowing bone grafting to correct both soft and bony defects of mandibular region

본 연구지역은 절취사면 연장이 약 450m에 달하며 사면 절취결과 암질의 측방변화가 현저한 지반조건을 나타냈다. 사면 안정대책의 수립을 위해 절취사면에서 구성암석, 지질구조, 불연속면의 방향성 등 지질공학적인 조사를 수행하였다. 절취사면의 방향성, 사면높이, 지반조건 등을 고려하여 6개의 Zone으로 구분하고, 안정성 분석은 불연속면의 방향성과 사면의 절취방향간의 기하학적 상관관계에 의한 안정성 분석이 가능한 DIPS 프로그램을 이용한 평사투영법으로 실시하였다. 사면안정성 분석결과를 바탕으로 시공성, 안정성, 경제성을 고려하여 비교적 큰 암괴의 이완시 도로 하단부에 미치는 영향을 최소화 할 수 있는 고강도 낙석 방지망(high tensile steel wire net) 설치, 사면 보호공, 옹벽의 증고 등 다양한 공법으로 사면안정 대책을 수립, 시행하였다. The length of study area was about 450m, and it was shown the geological condition of distinguished change of rock by cutting slope. In order to establish a slope stability, we carried out an engineering geological investigations about rock constituent, rock structure and a direction of discontinuous plane. The study area was divided into six section considered by direction of cutting slope, height of slope and geological condition. Analysis of cutting slope stability was carried out with stereo-graphic projection method by DIPS program which was feasible of stability analysis with geometrical correlation for a direction of discontinuous plane and direction of cutting slope. From analysis of cutting slope stability considered by construction, stability and economical efficiency, the slope stability countermeasures such as a high tensile wire net, slope protection method and enhanced retaining wall were established and operated which minimized effect caused by lower end of road on a relaxation of huge rock.

Racemic N-benzylaspartic acid (4) was prepared from maleic anhydride and used to modify and develop some efficient methods for the preparation of N-benzylaspartic anhydride hydrobromide (5). Thus, successive treatment of the compound 4 with 30% HBr in acetic acid and acetic anhydride afforded the title compound 5 in 75% yield. From this compound 5, ${\alpha}$-benzyl and ${\alpha}$-methyl N-benzylaspartates were also prepared.

The purpose of this study was to examine the sources of stress suffered by college golfers to present basic data for stress sources scale. 205 college golfers responded to open-questionnaire about the sources of stress at golf activity. Four college golfers participated in interview. The collected data were analyzed by the inductive analysis. Firstly, all interviews were tape-recorded and transcribed verbatim by the investigator. Secondly, all interviews were reviewed multiple times by the investigator and the peer debriefer. Thirdly, raw data themes were emerged from the data from the interviews and from the information gathered from the open-ended questionnaires and were organized into theme groupings. Fourthly, several levels of analysis were done by reviewing the transcriptions and open-ended questionnaires, and themes and patterns were generated based on the data. Levels of analysis included analyzing across interviews and open-ended questionnaires by common ideas, words, or phrases, and by category, across participant, by interview question across the interviews and open-ended questionnaires, by research question, and by comparing and contrasting the transcriptions with the peer debriefer to form the main themes. Lastly, through the levels of analyses, themes and general dimensions were emerged from the data. The inductive process was completed when no further significant grouping of ideas combined. The results of this study were as follows. The revealed sources of college golfers` stress were; psychological stress, interpersonal relationship stress, situational stress, performance stress, physical stress. This results suggested that stress management program or stress adaption program for college golfers must be presented. Limitations of this study and future implications were discussed.
