        The purpose of this study is to investigate and reveal the effects that the complex exercise training consisting of aerobic exercise and strength training(sit up, push up) that everyone can easily practice regardless of a time and a place in order to manage practically the physical strength of the aged affects the difference on their body composition and the change of physical fitness level. Looking into the change of body composition of an experimental group, the weight of 2.5kg was reduced after applying complex training for 12 weeks and the body fat mass of 2.65kg was reduced. Also, the abdominal fat of 0.13% was decreased and the muscle mass of 1.56kg was increased. For the change factors of physical fitness, cardiovascular endurance, muscular strength, muscular endurance, balance and flexibility excluding agility showed significant improvement after applying complex exercise training. The improvement of health fitness of the aged under this study was significantly effective to improve specified body functions which had been lowered by aging and insufficient physical activities. So, it is regarded that their health fitness is the important factor to improve the activity competence required for daily life and to lead healthy living by the improved activity competence. Henceforth, it needs to study more the complex composition of several sports, exercise intensity and the frequency based on the previous researches and studies. In addition, it needs to develop the complex exercise training in accordance with various characteristics such as a sex of the aged, an age, a physical fitness level, environment, a disease and the program in consideration of the efficacy and safety during training.

        The purpose of this study was to analyze and compare the effect of resistance exercise and balance exercise on proprioception and WOMAC index of patients with degenerative knee osteoarthritis. A total of 40 subjects participated in this study. The subjects were diagnosed with degenerative knee osteoarthritis and all were more than 60 years old. They were divided into three groups. Group Ⅰ(n=8) was trained with resistance exercise, Group Ⅱ(n=6) was trained with balance exercise and GroupⅢ(n=6) was trained with range of motion as a control. The results of this study were as follows. It was significantly indicated that the resistance exercise group and balance exercise group elicited error-reduction on proprioception goal-angle (p<.05). There was a statistically significant difference on proprioception between resistance exercise group and control(range of motion) group. There was a statistically significant reduction on WOMAC index between resistance exercise group and balance exercise group (p<.05) and on the WOMAC index between resistance exercise group and range of motion group(p<.05). In conclusion, resistance exercise and balance exercise are effective on degenerative knee osteoarthritis and resistance exercise is the most effective for improving proprioception and WOMAC index. More research on the intervention according to the degree of degenerative knee osteoarthritis is needed.

        This study aims to reveal how EA affects BAX and NF-kB involved in cell deaths from global ischemia, and to do this, observes the changes of BAX and NF-kB caused by EA application after transient global ischemia. The experimental method is to give rise to global ischemia and apply EA to 27 SD rats with the particulars of being six-week-old, male, around-300 gram-weighing, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 EA group(n=9), L14 EA group(n=9), no-treatment GI group(n=9), and then observe their changes of BAX and NF-kB at the time lapse of 6 hours, 9 hours and 12 hours after ischemia, using western blotting. The numerical decrease of BAX expression at the time lapse of 9 hours after EA application, though not statistically significant, was observed in GV20 EA group and L14 EA group, and the NF-kB expression appeared statistically significant decrease in GV20 EA group and L14 EA group, but the expression was higher in the group with EA application. Therefore, EA application at the early phase of global ischemia is considered to affect BAX and NF-kB and play a positive role in decreasing apoptosis and cell deaths by inflammation.

        The beetle family Ciidae, represented by Octotemnus laminifrons Motschulsky, 1860 and Octotemnus japonicus Miyatake, 1954 is presented for the first time in Korea. The beetle family Ciidae Leach is a relatively moderate family, which comprises about 640 described species in 42 genera worldwide. This family is distributed throughout the world. Ciids are minute fungus-feeding beetles, which are associated with the mycelia and fruiting bodies of wood-rotting fungi. These beetles are considered mycetobiont because they depend upon the basidiocarps for food and breeding throughout their life span. And also ciids are important components of the saproxylic fauna of many forests ecosystems and a number of species are considered rare or threatened and are associated with old growth forests or undisturbed forest conditions. A habitus photographs of adults, description, illustrations of diagnostic characters, and host fungi are provided.

        Since physical therapy was first introduced in Korea, it has been 50 years past and Korean physical therapy has made rapid progress. However, history or educational system of Korean physical therapy is still not known worldwide. Now, for Korean physical therapy to go beyond Asia and leap toward the world, endless studies, efforts and publicity are required. Korean physical therapy first began by missionaries dispatched from other countries like America and Canada with Korean War, which occurred in 1950. After the War, Korean Physical Therapy is devel˗ oped very fast. Korean Physical Therapy Association was founded in October 1, 1965 and many physical therapist were discharged. Korea became a full member of World Confederation of Physical Therapy(WCPT) in 1974, and held the 2nd Asia Pacific Confederation of Physical Therapy assembly in 1984 and WCPT assembly in 2005. Today, in 2010, licensed physical therapists are about 35,000 and there are physical therapy departments in 74 universities, and 17 uni˗ versities have master's or doctor's degree courses. And there are many academic journals(more than 10) related to physical therapy that are published. Many Korean physical therapists are working at various countries like America or Australia, and are acknowledged with excellent treatment technology and academic studies. This thesis aims to shed new light to the history and educational system reorganization of Korean phys˗ ical therapy and introduce it to the world, and establish the historical foundation to develop Korean physical therapy into the international level.

        2 week study was conducted to investigate the effects of Interferential Current(IC) and Kaltenborn-Evjenth Orthopedic Manual Therapy(KEOMT) on functional constipation. Interventions were applied to spinal segments between T9-L2 which provides innerva˗ tions to the gastrointestinal tract. Subjects(n=24) were randomly allo˗ cated to two treatment groups: the IC group or the KEOMT group. Results for the IC therapy demonstrated significant decrease with the colonic transit time(CTT) as well as scores on the constipation assessment scale(CAS). The frequency of defecations per week had increased significantly(p<0.05). The KEOMT displayed decreased CTT in the left colon region. The scores on the CAS were reduced and frequency of defecations per week had increased significantly (p<0.05). This study not only showed that both modes of therapy improved symptoms of constipation, but also optimized gastrointesti˗ nal content movement, eventuating in a more normalized CTT. In conclusion, both the IC therapy and the Kaltenborn-Evjenth Orthopedic Manual Therapy have shown to be effective interventions for improving functional constipation.

        This study has been conducted on the subjects of eight undergradu˗ ate students with abdominal obesity and eight undergraduate stu˗ dents with normal weight to find out correlation between substantial fatigue and Ratings of perceived exertion through analysis of their blood components when they took exercises to strengthen their abdominal muscular power. Comparatively analyzing HDL-C, LDL-C and lactic acid before and after they took sit-up at level of RPE 19-20, no statistically significant differences in HDL, LDL, lactic acid meas˗ ures were observed between groups, but a significant difference in RPE was noted between groups(p<0.05) Our findings suggest that control group showed no significant differ˗ ence in increase of fatigue material whereas the obese group showed a lower frequency of sit-up, though both groups took the same abdominal exercise. Additionally, the lower frequency of sit-up in obese group results from relatively higher Ratings of perceived exer˗ tion rather than increase of substantial fatigue material. This study invites future research that examines the effect of a comprehensive obesity exercise program combined with dietetic

        Spider mite is the most concerned pest in apple production. This study compared and analyzed the historical changes of two mite pests, Tetranychus urticae koch and Panonychus ulmi (Koch) in 16-30 representative apple orchards in the major apple production area; Gyeongnam, Gyeongbuk, and Jeonbuk province of Korea from 1992 to 2007. Monthly sampling of 100 leaves per orchard provided the basic data of population density of two mite species. Among those orchards, chemical spray history was also analyzed from four orchards, which could be representatives of IPM practitioners. It was found that overall population densities of T. urticae were higher than those of P. ulmi for 16 years. Before 2000, T. urticae was dominant over P. ulmi in most orchards. However since 2000, P. ulmi have occurred more than or as much as T. urticae.. Moreover, although there was large fluctuation of occurrences of two mite species over the years and localities, spider mite pressure appeared to decrease, in general. It seemed to relate the timing of ground cover management with pheromone-based IPM implementation nationwide from late 90s. Panonychus ulmi appeared to rise in April and July in general, fall in August, and go up again in the late season; September-October, while T. urticae appeared to begin to rise in June with July or August peak and sometime with late season second peak in October. Application frequency of acaricide has been dropped from four times in the late 1990s to 2.5 times in the late 2000s.

        In order to establish a year round indoor-rearing system for Copper butterflies; large copper butterfly, Lycaena dispar, the effect of temperature on larval development and diapause was investigated. Temperature has been suggested as an important factor regulating the developmental rate, length of life, and survival rate from insect. As temperature increased, the developmental period was gradually shorten. The developmental periods of large copper larvae had a range of 11.0 days to 28.5 days at 30℃ and 17.5℃ respectively. The highest emergence rate was 94.2% recorded at 20℃. And the low emergence rate was 72.7% under 17.5℃. We investgated the sensitive stages to diapause induction in the larger copper effect of temperature and photoperiod. The experiment involves transfer of individuals from diapause averting (LD 16:8h, 25℃) to diapause inducing condition (LD 8:16h, 20℃) at various stages. Diapause was induced in 95.2% insect transferred at hatching larvae, in 15.6% of insects transferred at 2nd stadium molt, in 0% of insects transferred at after 3rd stadium molt. Percentage diapause induction increase with the length of short days and low temperature experienced. The main stage sensitive to photoperiod and temperature induction of diapause determination is the early first larval instar. The diapause induction began 14 days and ended 20 days after hatching larvae (LD 8:16h, 20℃).
