풀무치(Locusta migratoria)는 메뚜기과에 속하는 곤충으로 70% 이상의 단백질을 함유하고 있어 식사료용 곤충으로 이용 가능성이 높다. 그러나 풀무치의 대량생산을 위한 연중사육 관련 연구는 미흡하여 사육방법 정립, 먹이원 선발 등이 필요하다. 본 연구에서는 풀무치의 연중사육을 위한 방법으로 사육밀도에 따른 생육 특성과 최적 산란처를 찾기 위해 상토, 오아시스 등을 이용하여 산란 특성을 조사하였다. 풀무치의 생육 온도는 28℃, 습도는 65% 내외로 유지하고 처리구별 생존율, 탈피횟수, 크기, 무게 등을 측정하였다. 사육밀도별 약충 기간은 32일 소요되었고, 생존율은 82~90 %였으며, 성충 기간은 110~120일 소요되었다. 산란처별 난괴 길이는 33~49mm였으며, 부화 후 생존율을 72~82%였다.

The effect of the ionization energy on the common house mosquito, Culex pipiens, pupa was investigated as the hatching rate, longevity and detoxification enzyme activity. The longevity of adult emerging in the pupa decreased depending on the exposure dose of Gray (Gy) in Cx. pipiens. The hatching rate of the F1 generation egg derived from Cx. pipiens pupa treated up to 70 Gy did not show any difference with the control, but the eggs did not hatch 100% at 120 Gy exposure. These results showed that Cx. pipiens was sterilized at 120 Gy. Several detoxifying enzyme (GST, non-specific esterase and MFO) activity of Cx. pipiens adult emerged from pupa irradiated with 120 Gy was investigated. The difference in activity was observed in female than in male irradiated with electron beam. As a result, electron beam irradiation seems to affect enzyme activity as well as induce infertility of Cx. pipiens.

The tobacco cutworm, Spodoptera litura(Fabricius) is serious pest that hurts tomato crops, actives long time of the year. Without pesticide applications, sex pheromone delta traps through experiment first and second half setting during cultural seasons in glasshouse and greenhouse. We investigated captured number of S. litura both in and out side of the two type of tomato cultivated greenhouse. As a result of investigation, captured number of S. litura showed the wave and three high peak typed graph throughout 10 months experiment. First time expression of S. litura was late April in outside installed traps and after that occurrence rate increased gradually until late August. In september, the rate decreased remarkably to middle November in both in and out side treated traps. The result also expressed that captured average number of S. litura in inside of the greenhouse were 8~10 units, and were 15~20units in outside treated traps. Simultaneous installation of internal and external sex pheromone traps succeeded in eliminating a considerable number of S. litura male moths, and the number of larvae was expected to be considerably reduced. Consequently in the experiment, captured male number of S. litura were about 220 units in outside, on the other about 80 of S. litura captured in inside installed traps.

최근 봄철 기온이 높아짐에 따라 마늘 뿌리응애 피해가 늘어나고 있는 실정이다. 이러한 뿌리응애 피해를 최소하 하고자 발생양상과 22종의 약제에 대하여 살비효과를 조사하였다. 마늘 재배시기 중 뿌리응애의 발생은 충북 보은 등 5지역에서 2015년부터 2017년까지 3년간 3월부터 6월까지 뿌리응애 발생밀도를 조사하여 발생양상을 확인하였다. 뿌리응애는 2016년에 가장 많이 발생하였으며, 발생시기는 월동 후 3월 상순부터 발생하여 6월 중순경까지 지속적으로 밀도가 높아지는 양상을 나타내었다. 조사된 5지역 중 가장 높은 밀도로 조사된 보은지역은 6월 상순경 주당 13.3마리가 발생하였다. 뿌리응애에 대하여 우수한 살비효과를 나타낸 약제는 분무처리시 약제처리 10일 후에서 dimethoate, azocyclotin, abamectin, hexythiazox, cabosulfan, spirotetramat, benfuracarb가 90% 이상의 살비효과를 나타내었다

본 연구는 고농도 CO2 환경에 순응한 호접란 유묘의 CO2 교환 및 생장 반응을 조사하기 위해 실시하였다. 환경 조절이 가능한 식물생장상에서 6주령 호접란 ‘만천홍’을 27주 동안 야간에 각각 400 ± 100, 900 ± 100, 1500 ± 100, 2100 ± 100μmol CO2·mol-1 농도로 유지해주었다. 처리에 앞서 발달해 있었던 최상위 성숙엽으로 측정한 야간 중 CO2 흡수량은 900μmol CO2·mol-1 처리구에서 가장 높았고, 이어 2100, 1500, 400μmol CO2·mol-1 순으로 높았다. 그러나 처리 7주 이후 새로 발달한 성숙엽에서 측정한 결과, 2100μmol CO2·mol-1 처리구가 야간 중 가장 높은 CO2 흡수량을 보였으며, CO2의 흡수량은 처리 CO2 농도가 높아질수록 증가하는 경향을 보였다. 생장 반응에서는 최상위 성숙엽의 엽장, 엽폭 및 생체량은 900, 1500, 2100μmol CO2·mol-1 등 고농도 처리구에서 감소하였으나, 신엽 발달은 고농도 CO2 처리 하에서 촉진되었다. 이러한 결과들은 호접란 유묘의 높은 CO2 환경에 대한 적응이 CO2 흡수와 신엽 발달을 증진시킬 수 있다는 것을 보여준다. 그러나 900μmol CO2·mol-1 이상의 고농도에서는 잎의 생장과 생체량이 다소 줄어드는 경향이 있어 이에 대한 원인구명 등 추가적인 연구가 필요하다.

The purpose of this study was to investigate the effects of core muscle training on balance ability. Forty subjects in their 20s participated in a 6 week core muscle training program. Balance ability before and after the intervention were assessed and analyzed using the Romberg test, which was conducted on the floor, pedalo, and balancefit. The differences between the measurement methods of balance ability using varied platforms was also compared and analyzed. After the 6-week core exercise training program, the training group represented statistically significant increases in all 3 methods for static balance ability. In the control group, all 3 methods represented no statistically significant increases. Upon comparing the different methods of the Romberg test, there were no notable differences between conducting the test on varying platforms for both groups. This study suggests that the core muscle exercise training program increased the balance ability.

The purpose of this study was to compare the effects of respiratory exercise on cardiopulmonary function and muscle activity of rectus abdominis in smokers and non-smokers with elderly people. All the participants were older than 65 years, and twenty non-smokers, and twenty smokers participated. Non-smokers and smokers were randomly divined into 10 feedback breathing exercises (FBE) and a balloonblowing exercise (BBE) group. The FBE and the BBE were performed three times a week for four weeks. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), forced expiratory volume at one second/forced vital capacity (FEV1/FVC), peak expiratory flow (PEF), and vital capacity (VC) were measured as pulmonary function. EMG was used to measure the activity of the rectus abdominis. In the FBE and BBE groups, FEV1 was significantly lower in non-smokers compared to smokers at two and four weeks (p<.05), FEV1/FVC, PEF and VC were significantly lower in non-smokers compared to smokers to pre-test, two weeks, four weeks and six weeks (p<.05). Muscle activity of rectus abdominis was significantly difference in the BBE group at pre-test, two weeks, four weeks, and six weeks (p<.05). These results suggest that respiratory exercise was effective in improving pulmonary function and rectus muscle activity.

The diamondback moth (DBM), Plutella xylostella, is a globally distributed and important economic pest. Chemical control is the primary approach to regulate populations of this pest. Chlorantraniliprole is the first commercial insecticide that belongs to the new chemical class of diamide insecticides. In this study, the resistant strain was observed 1578-fold resistance to chlorantraniliprole. Point mutation (G4946E) in ryanodine receptor (RyR) showed a high frequency. Enzyme assays indicated that glutathione S-transferase (GST) activity in the resistant strain was 2.4 times higher compared with the susceptible strain, whereas no difference was seen for P450 and esterase. In addition, the expression of two GSTs genes was up-regulated. These findings pave the way for the complete understanding of the mechanisms of diamide insecticides resistance in insects.

This study used both kinesiotaping and extracorporeal shock wave therapy on patients diagnosed with frozen shoulder - a common musculoskeletal disorder in adults - in order to observe the effects on the joint range of motion. 21 adult(male 12, female 9) were selected and distributed into randomized groups. One group received kinesiotaping (n=10) and the other group received kinesiotaping together with extracorporeal shockwave therapy (n=11). After a 6 week duration of receiving kinesiotaping and extracorporeal shockwave therapy, changes in the joint range of motion in the patients were observed. Post-treatment of frozen shoulder, the changes in abduction within the shoulder joint were as follows: in both groups there was a noticeable increase in the joint range of motion (p<.05). Post-treatment of frozen shoulder, the changes in external rotation within the shoulder joint were as follows: both groups showed a significant increase in the joint range of motion (p<.05). The result of suggest that, it can be inferred that both the extracorporeal shockwave therapy and kinesiotaping are effective in increasing the joint range of motion in patients with frozen shoulder.

This study investigated the effects of indirectly applying proprioceptive neuromuscular facilitation (PNF) to the scapular adductor muscles of stroke patients on their scapular movements and walking ability. Five patients who were diagnosed with stroke participated in this study as a single group. PNF patterns were applied to the scapulae anterior elevation and posterior depression patterns and upper limbs patterns of the patients in side lying and sitting positions together. The data were analyzed with a paired t-test in order to identify within-group differences in the measurements before and after the intervention. The scapular movements of the upper and lower parts, weight bearing and walking speed were significantly improved in the stroke patients after the application of PNF (p<0.05). These results suggest that PNF training effective in improving the scapular movements and walking ability in patients with stroke.

Nanoemulsions are actively used in several applications for pharmaceutical, cosmetic and chemical industries. In this study, we propose the use of microfluidizer known as high pressure homogenizer to prepare lipid nanoemulsion as a potent cosmetic delivery carrier. The lipid nanoemulsions were prepared by O/W emulsion with hydrogenated lecithin and different type of oils. Effects of oil type on the stability of the lipid nanoemulsion were investigated with Dynamic Light Scattering (DLS) and Zeta-potential. Arbutin was used as model drug for transdermal administration through hairless mouse skin. Transdermal arbutin delivery using the lipid nanoemulsions was studied with HPLC method.

The purpose of this study was to determine the effects of music therapy and ball exercise on women experiencing menstrual discomforts, thereby identifying the validity of these methods as interventions against menstrual discomforts, with a particular goal of presenting basic data for clinical use. Twenty university students in their 20s were assigned to two therapy groups in a sequence via simple random sampling; ten subjects attended a ball exercise combined with music therapy group and the other ten subjects attended a music therapy group. Ball exercises were conducted 3 times per week for a total of 12 times, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Similarly, the subjects participated in music therapy by listening to music for 35 minutes per session and 3 sessions per week, starting from 3 weeks before the expected first day of the menstrual period and ending on the last day of the menstrual period. Five out of six categories of menstrual discomforts were significantly decreased in both music therapy and ball exercise, the exception being changes in the autonomic nervous system, while those in the music therapy group showed a significant difference only in the category of behavioral changes. The results of the present study demonstrate that the ball exercise combined with music therapy more effective in improving menstrual discomforts than the music therapy group.
