The purpose of the research is to figure out the problem of skiing-lesson to handicapped person and to develop and verify skiing-lesson manual by exploring skiing lesson's main factors of handicapped. To achieve the object of the research, we have done a survey to 14 people who agreed on participating in the research by doing open type-questionnaire survey to explore the obstructive factors of ski-vitalization for the handicapped. We have chosen two professor of adapted physical education, two ski specialists for the handicapped, and two instructors for national ski team to the adaptive to analyze the priority of ski-lesson to handicapped. There were a few results the result of developing the skiing-lesson manual for the handicapped was classified by 4types according to the types of disability. (two-track, three-track, four-track, monoski).

The purpose of this study was to identify the analysis of the difference between accident type and injury type on ski resort. In order to achieve this purpose, a total of 522 persons recorded in the safety accident logs of two ski resorts located in Gyeonggi - do in 2016-2017 winter season by the purposeful sampling method. Frequency analysis, chi-square test were executed using SPSS Statistics 21.0 Version. As the results, the following conclusion was derived. First, injury part differ statistically and significantly according to both socio-demographic variables(lesson experience). Second, injury type differ statistically and significantly according to both socio-demographic variables(event, lesson experience, event${\times}$age, lesson experience${\times}$gender).

Purpose: This study is to analyse the injury patterns of knee ligament and the factors influencing ligament injuries of knee, and to evaluate the changes of knee function and activity after ski injury. Materials and Methods: Thirty cases of ligament injuries of knee were studied with a questionaire, stress radiographs, magnetic resolution imaging, and physical examination. Mean age was 28.6 years old and mean follow up was 29.6 months. Clinical evaluation of Lysholm knee scoring scale was used for knee function and Tegner activity score was used for activity change after ski injury. Results: The anterior cruciate ligament (ACL) injury accompanied with medial collateral ligament(MCL) injury was most in 11 cases and isolated MCL injury was the next in 9 cases. The common types of injury mechanism were Phantom foot phenomenon (13 cases, 43$\%$) and valgus external rotation injury (12 cases, 40$\%$), which constitute 83$\%$ of all case. At the last follow up, the mean Lysholm score was 93.4 and mean Tegner activity score was 4.2. The reduced Tegner activity score after injury was 1.9. Among several injury groups, the evaluation of knee function and activity was best in the isolated MCL injury group and worst in the ACL injury accompanied with MCL injury group. The factors to influence ski injury were participation to ski class, release of binding, and skiing long time more than 2 hours. Conclusions: Lysholm score at last follow up revealed good grading, but sports activity after ski injury was reduced when compared with pre-injury state. It seems to need a active, systemic sports rehabilitation program after sports injury.

Only data from 221 respondents however were used after screening data for reliability, and SPSS for Windows(21.0 version) statistical program was used to conduct descriptive analysis, factor analysis, reliability analysis, paired samples t-test analysis, independent samples t-test analysis and IPA matrix analysis. The following results were obtained. First, significant differences between the level of satisfaction and the level of importance were found for part of the selection attributes for each group. Second, Iquadrant was included with meals and information provided factors. IIquadrant was included with instructors and class program, information provided, accommodation factors. IIIquadrant was included in accommodation and meals, time-distance factors. IVquadrant was included in the information provided factor.
