1998년부터 2000년까지 3년간 경북사과주산지 사과원과 묘목원을 대상으로 잎말이나방류 종을 조사하였으며, 1992년부터 2001년까지 10년간 5-6개 시군의 관행사과원과 폐원에서 잎말이 나방 발생동향과 피해정도를 조사하였다. 사과원에 발생하는 잎말이나방으로는 애모무늬잎말이나방 (Adoxophyes orana), 사과무늬 잎말이나방(Archips breviplicanus), 매실애기 잎말이나방(Rhopobota unipunctana), 사과잎말이나방(Choristoneura longicellana), 복숭아잎말이나방(Acleris fimbriana), 감나무잎말이나방(Ptycholoma lecheana circumclusna), 한국잎말이나방(Archips subrufanus) 등 총 7종이 조사되었다. 이중 애모무늬잎말이나방이 매년 단연 우점종이었으며, 사과무늬잎말이나방과 매실애기잎말이나방은 특정 해에만 1-2 농가에서 다발생하였다. 1980년대 우점종은 사과무늬잎이나방과 매실애기잎말이나방이였으나, 1990년대말 우점종 변화가 이루어진 것으로 조사되었다. 10년간 관행사과원의 잎말이나방 피해정도를 조사한 결과, 평균 피해과율은 $0.67\%$였다. 과실 피해는 3세대 유충에 의해 8-10월에 집중적으로 이루어졌다. This study investigated the species of leafrollers in apple orchards and nursery farms in Gyeongsangbuk-do for three years from 1998 to 2000, and also examined the occurrence and damage of leafrollers in commercial apple orchards in 5-6 cities and districts for 10 years from 1992 to 2001. Total seven species of tortricidae were found in the apple orchards, which were Adoxophyes orana, Archips breviplicanus, Rhopobota unipunctana, Choristoneura longicellana, Acleris fimbriana, Ptycholoma lecheana circumclusna and Archips subrufanus. Among them, A. orana was dominant species every year, and A. breviplicanus and R. unipunctana occurred with a high density in one or two farms in some years. The dominant species in the 1980s were A. breviplicanus and R. unipunctana, but it was considered that dominant species have been changed in the late 1990s. According to the result of leafroller damage in commercial apple orchards for 10 years, the mean fruit damage rate was $0.67\%$. Fruit damage was observed frequently between August and October by third-generation larvae.

In this study, 18 women in their 50s and 60s diagnosed with rotator cuff syndrome (M75.1) were recruited from the local community in C City and underwent exercise rehabilitation at a living lab. Shoulder disease was diagnosed through examination by medical staff at M Oriental Hospital, a designated hospital, and all subjects voluntarily agreed to participate in the study. Participation in this study was confirmed through a basic health questionnaire and an interview with a specialist, and only the affected side was applied. Exercise rehabilitation was conducted three times a week for 12 weeks. To confirm the study participants reduction in rotator cuff syndrome pain and increase in shoulder joint range of motion, visual pain scale (VAS: Visual Analogue Scale) and shoulder joint range of motion were measured. Exercise rehabilitation was individually tailored by resetting the exercise intensity, exercise composition, and exercise time using the ARES exercise rehabilitation program developed by the Electronics and Telecommunications Research Institute. Exercise rehabilitation was carried out at the Living Lab(Gymnasium, a designated sports center), and exercise rehabilitation was guided by an exercise instructor who had obtained bodybuilding as a sports instructor. As a result of exercise rehabilitation, both the visual pain scale of the shoulder decreased and the shoulder joint range of motion increased. Therefore, the above conclusion has been verified that pain is reduced and shoulder joint range of motion increases when exercise rehabilitation using the ARES program is performed by operating a living lab in the community.

Encouraged by the sport-for-all movement in which the general public can participate in accordance with the national sport-for-all promotion policy since the 88 Seoul Olympics, the aerobic exerase has been activated and now show the highest level of prticipation and preference among the sport-for-all events. Therefore, the lack of athletic directors has occurred with the increasing number of aerobic centers. And the mass production of unqualified sports lecturers has brought about great confusion. The occurrence of injury from exercise has caused a soaal problem To resolve this problem, the Korean Aerobics Health Science Institute opened the in-service training center for the first tirr~ in Korea and provided people with in-service training. But it has thus far been discontinued due to the excessive numbers of interested orgranizations and the absence of administrative support.The present situation of support for sport-for-all directors over the period between 199 and 2001 showed that the highest rate of support for aerobics has a great contribution to the sport-for-all movement. An attempt was made to investigate the present situation of the present public certified 3rd-class aerobics directors` license system. As a result, the following problems were raised: 1. In-service education and training has na curricular contents concerning the speaalty field of aerobics. It is difficult to make an accurate judgement of whether to pass the qualifying examination in the theoretical test through the practise test and the oral test or intrview. 2. Athletic directors are not provided with an opportunity to renew the license through the reorientation over the 10-year period of in-service training. 3. Each of the in-serivce training centers show the unbalanced rate of successful passage. 4. The current qualifying examination for pubic certifed aerobics is poorer in content than the qualifying examination conducted by aerobics organizations. The current qualifying examination system through the in-serivce training of public certified aerobics directors should be transferred to the reliable specialized aerobics organinzations. Then, specialized and systemmatic education armed with theories and practice could be reasonable provided for aerobics directors by considering the specificity of aerobics exercise. This can meet like-minded people`s needs through aerobics exercise science for national health promotion by conducting a study on saentific information and new types of exercise in the rapidly changing contemporary society. And it is neesssry to provide institutional support for training and education of athletic directors that can educate the athletic director taking the initiative in developing and inseminating the sports program.
