The aim of this study is to observe the attraction of four colored lights against beet armyworm (Spodoptera exigua). The visual preference of the beet armyworm for light-emitting diodes (LEDs) was examined by LED equipped phototactic chamber in the dark room at 27 ± 0.5°C and 60 ± 5% relative humidity. Evaluated specific wavelengths of LEDs were blue (470 ± 10 nm), green (520 ± 5 nm), yellow (590 ± 5 nm) and red (625 ± 10 nm), and compared with that of the commonly luring lamp used fluorescent (380-800 nm) which served as controls. The light intensity was tested at 20, 40, 60, 80 and 100 lx, and light-exposure time was determined at 20, 40, 60, 80 and 100 min. All of the light treatments with 40 lx intensity and the 60 min light-exposure time showed the highest attraction rate to S. exigua. Based on attraction rate of the green LED (88.9%) was the most attractive to S. exigua, followed by blue LED (81.1%), yellow LED (63.3%) and red LED (56.7%). In comparisons with LED and fluorescent light, the attractive rate to green LED against beet worm was more effective than that of fluorescent (80%) light. Overall, these results indicated that the eco-friendly LED could be a more effective substitute for the chemical free insect pest control system because of the various advantages.

The purpose of this study was to find the level of satisfaction and preferences regarding the mess provisions in the three military bases in Daegu, Korea. A total of 325 military personnel was surveyed for this study. The content of examinations consisted of the general characteristics, satisfaction, awareness, and preference for the mess. Furthermore, I investigated the general menu on a daily basis with the most or the least-preferred food. As a result, I found that fried dishes are most preferred by military personnel, and they second and third in their preferences are boiled, and mixed with dressing. I also found that military personnel like meat, sweets like ice-cream, fried pork chops or chicken, and fatty and processed food like hamburgers. On the other hand, they do not like dishes made with bean sprouts, squid, fish or kimchi. On the basis of the results, a balanced diet is needed for military personnel through the research and development of recipes using some of the least favorite ingredients such as fish, squid, and vegetables.

 ,  , This study was conducted to investigate food preference and developmental characteristics of the gray field slug, Deroceras reticulatum Muller (Stylommatophora: Limacidae) using various foods. The food preference of D. reticulatum was most highest on Chinese cabbage (Brassica campestris L.), followed on cucumber (Cucumis sativus L.), and significantly low on beet (Beta vulgaris var. Ruba), kale(Brassica oleracea L. var. acephala D.C), carrot (Daucus carota L.) and Chinese cabbage (Brassica campestris L.) which were not different significantly. The total number of eggs laid by D. reticulatum was the highest (n = 109.6) on cucumber and the lowest (n = 10.1) on leaf perilla (Perilla frutescens var. japonica Hara). Hatchability was the highest (92.4%) on cucumber and the lowest (62.5%) on leaf perilla. The egg developmental period was not significantly different from 12 days to 13 days among host plants. Juvenile period and adult longevity ranged from 75 days to 111 days and 66 days to 187 days, respectively. Thereby, life span from egg to adult longevity of D. reticulatum was the longest on cucumber with 273 days and the shortest on 190 days on leaf perilla.

The effects of different ingredient formulations on physicochemical qualities and consumer preferences were investigated using Baikseolgi incorporated with perilla powder, a healthy food ingredient, as a model system. Perilla powder was incorporated into the formulation at five different amounts (0%, 5%, 10%, 15%, and 20% (w/w)) by replacing equivalent amount of non-glutinous rice flour. After appropriate mixing, rice cakes were steamed and quality attributes were evaluated after cooling. The pH increased but moisture content decreased significantly with an increase in the perilla powder substitution (p < 0.05). Lightness (L*) decreased significantly from 80.32 to 70.73 with the higher incorporation of perilla powder (p < 0.05), indicating that the color of Baikseolgi became dark. Redness (a*) and yellowness (b*); on the other hand, increased significantly (p < 0.05). Hardness decreased significantly as the perilla powder content increased in the formulation (p < 0.05). With respect to overall acceptability, the control received the highest mean score of 5.90; however, this was not significantly different from all samples tested except for 20% sample (p > 0.05). Five percent sample received the highest or competitively high preference scores in all attributes; thus, incorporation of 5% perilla powder in the formulation of Baikseolgi would be recommended while taking advantages of the health benefits of perilla without sacrificing the quality acceptance by the consumers.

This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

Foraging preference in prey size and type is influenced by a variety of factors including energy requirements, season-dependent food availability, and social context (e.g. competition and predation risk). The oriental stork (Ciconia boyciana) is known as a wetland forager that inhabits human-managed wetlands such as paddy fields while breeding. However, it became an internationally endangered species. Information on its foraging preference is anticipated to play an important role in maintaining storks in captivity with a variety of food types as well as managing the food availability in foraging habitats of reintroduction sites. Specifically, the present study investigated the patterns of foraging preference of the subject in captivity as a partial study of the prerelease training and habitat management programs prior to reintroduction. The observations of foraging behavior of breeding adult storks included foraging preference in prey size (i.e. small, less than 6 cm, vs. large, larger than 6 cm, mudfish) during the incubation and nestling periods (March to April of 2009~2010) and prey type (i.e. mudfish, Misgurnus spp., crickets, Gryllus spp., and earthworms, Lumbricus spp.) during the postnesting period (October of 2009~2010). Our results indicated that storks in captivity not only preferred large to small mudfish independent of breeding stage but also preferred mudfish to crickets and earthworms. To our knowledge, captive storks did not appear to be constrained by providing offspring with various mudfish size and were likely dependent on mudfish, suggesting that a mudfish population in paddy fields should be monitored and managed for the main food resource for breeding storks prior to reintroduction.

In the future, smartphone convergences are not only based on the on/offline integration, but also with the integration between mobile communications and broadcasts. Therefore, there is a need to search for new direction of mobile device that enables variety user applications that are different from the existing size and application issue. The aim of this reserch is to improve user interface of smartphone's functional attribute. The survey results in this paper showed that the most preferable attribute of smartphone among the 8 was the wireless internet 25.3%, followed by messaging 20% and application 19.8%, which totaled to 62.5%. But the samples used were mostly limited to those aged 20 through 30. So the results are not considered as a representative preference of all smartphone users, and should be considered otherwise before materializing them to a product. Therefore, for the more liable results the further research should be conducted to gather data from a variety of users of all ages, and the functional attribute should be analysed through QFD.

Spodoptera exigua is a significant polyphagous pest in the greenhouse and open field. Our aim of this study was to evaluate light emitting diodes (LEDs) as the potential attractants against Spodoptera exigua on various wavelengths, light intensity, and light duration. The preference response to S. exigua was investigated by the laboratory and field-scale. The wavelengths of LEDs were composed as follows: blue (470 nm), green (520 nm), yellow (590 nm), red (625 nm) and white (450-620 nm). When the optimal light condition was investigated in the laboratory scale, the all light treatments attracted the highest number of S. exigua at 40 lux intensity and 60 min duration. Based on the wavelengths under optimal light condition, the white LED exhibited the highest attraction rate (91.1%), followed by green (88.9%), blue (81.1%), yellow (63.3%) and red (56.7%), respectively. In comparison with the selected white LED and yellow sticky traps in the field-scale, the white LED (81.3%) was about 16.26 times more attractive than yellow sticky trap (5.0%). These results clearly show that the white LED had the greatest attraction against S. exigua.

Male cicadas produce species-specific calling songs to attract conspecific receptive females, and they typically occupy tree trunks or branches during calling. We studied calling site preference in the natural environment for four species of cicada: Cryptotympana dubia, Meimuna opalifera, Oncotympana fuscata, and Meimuna mongolica. Males of M. opalifera tended to sing singly in trees, whereas other species were often observed singing together in one tree. In some cases, two or three individuals of different species sang together in one tree; the only possible pairwise combination not observed was M. mongolica with O. fuscata. Calling sites of the four species differed significantly in distance to the ground and distance to trunk, and both tree height and tree crown were significant factors for calling site preference in multivariate analysis of variance (MANOVA). Distance from calling site to the ground was highest in C. dubia, followed by M. opalifera, M. mongolica, and O. fuscata. The distance from calling site to the trunk was greatest in M. opalifera and differed significantly from those of other species, which tended to sing close to tree trunks. Males of M. opalifera were mobile when they produced calling songs, whereas males of other species were stationary. That is, males of M. opalifera sang only for short periods of time and moved around adjacent trees. Segregation of calling sites suggests that these four cicada species occupy different niches, thereby avoiding competition for calling sites as much as possible.

본 연구는 TV화면에 입체감을 표현하여 소비자의 구매 욕구를 촉진하는 TV홈쇼핑 식공간 연출에서 표현되는 공간 깊이감이 표현되는 연출의 특성을 파악하기 위해 2005년 3월에서 2010년 11월까지 C*홈쇼핑에서 실제로 방영된 식기 판매 방송 중 6개 브랜드 식기 판매 방송의 실제 연출 이미지 자료를 분석하고, 신뢰도 분석, 요인 분석과 다중 회귀분석기법을 사용하여 설문 조사를 통해서 감성 형용사 이미지어를 분석하였다.TV화면이라는 평면에 입체를 표현되는 연출의 특징은 크기의 비교, 중첩, 사선배치와 원근법적 배치로 추출하여 분석하였고, 식기방송에 주로 사용되는 카메라 앵글의 종류를 버즈 아이 뷰, 하이 앵글, 아이 레벨 등으로 구분하여 적용하였다. 이 분석의 결과로 정리되는 것은 소비자 선호도가 높은 연출은 브랜드 식기의 주요인에 높은 상관도를 보인 이미지어를 인식하는 경우라는 것이다. 따라서 카메라 앵글과 특성에 의한 선호 연출의 방향 제시가 가능하며, 소비자가 선호하는 정량적 데이터 베이스를 이용하는 새로운 개념의 공간 연출 개념이 가능하다고 본다.

인간의 감성에 직접적인 영향과 자극을 주는 색상자극에 대한 생체반응을 정량적으로 분석하기 위하여 3가지 색상 자극(Bright Yellow Red (BYR), Deep Green Yellow (DGY), Vivid Blue (VB))에 대한 뇌파 생리선호(Electroencephalography, EEG)와 선호도와의 상관관계를 연구하였다. 뇌파 분석을 통해 얻은 생체신호는 일반적인 색상의 이미지와 밀접한 상관관계가 있었다. 색온도가 낮을수록 뇌가 활성화 되었고(BYR ≥ DGY 〉 VB), 좌뇌보다 우뇌가 더 큰 생체반응을 보였다. 전체적으로 주파수 별 뇌파값은 베타파≥세타파, 알파파〉 감마파의 순이었다. 색온도가 낮을수록 Beta파의 뇌파 power 증가(BYR ≥ DGY 〉 VB)하였고, 그러고 나머지 파(세타파, 베타파, 감마파)의 경우에는 색온도가 낮을수록 이들 주파수의 뇌파 power가 증가(BYR ≥ DGY 〉 VB)하였다. 색상별 선호도와 뇌의 활성화의 상관관계는 색상에 대한 선호도가 높을수록 특정 주파수대의 뇌파가 활성화되었다. 선호도에 따른 뇌파반응은 좌 우뇌간에 유사한 생리적 반응을 보였으나, 후두부 보다는, 전두부에서 뚜렷한 상관관계를 보였다. 이러한 결과는 선호도가 높은 색상자극을 통해 특정 주파수 영역의 뇌파를 활성화가 가능하며, 색을 이용하는 다양한 분야(뷰티산업, 인테리어, 색채치료, 의상 등)에 적용가능성이 높다는 것을 의미한다.

Sweet potato whitefly, Bemisia tabaci, is one of the most common and critical green house pests in the world. The object of this study was to evaluate the attraction effect of various colored high power light emitting diodes (HPLEDs) against B. tabaci. These insects with diverse HPLEDs were examined by LED equipped chamber in the dark room at 27±0.5℃ and 60±5% relative humidity. Evaluated light-sources were blue (470±10 nm), green (520±5 nm), yellow (590±5 nm) and red (625±10 nm) HPLEDs, and tested with various illuminance intensity at 20, 40, 60, 80 and 100 lux. Base on the attraction rates, the green (94.4%) HPLED was the most effective against B. tabaci, followed by yellow (78.9%), blue (71.1%) and red (60%) HPLEDs. Furthermore, these data show that both the 80 lux intensity and 40 min light-exposure time using the green HPLED was the most suitable for attraction of B. tabaci. Putting all results, our data will provide the useful information for eco-friendly pest control against B. tabaci.

Alfalfa weevil, Hypera postica Gyllenhal, is regarded as one of the most important insect pests on Chinese milk vetch and hairy vetch. The insect usually feed on leaves, stems and pods of the green manure which causes severe reduction of biomass. This study was conducted to observe the occurrence of H. postica larva and adult on Chinese milk vetch in 2009 to 2010, and to evaluate host plants preference of 11 different seedlings in 2010, Milyang, Korea. Occurrence of H. postica larvae on Chinese milk vetch was observed to increase from early April clearly and its peak population was showed during middle to late April. The 1st generation of newly emerged adult of H. postica was appeared on 20th May. Newly emerged H. postica adult was fed on green manure such as Chinese milk vetch and hairy vetch as well as various seedlings located at nearby upland. And then the insects were migrated into aestivating places in middle to late of June. Thus, host plant preference of H. postica adults were evaluated with 11 different seedlings using transparent acrylcage and at Chinese milk vetch field. As a result, H. postica adult preferred on Chinese cabbage, followed by soybean, kale, foxtail millet and proso millet. The damaged rating of seedlings were shown to have the same trend with adult occurrence. In particular, few H. postica adults were occurred on eggplant, lettuce, corn, crown daisy and peanut, and thereby those crops were regarded as non-preference plants due to the absence of damage. These informations can be used by upland farmers who sowing from late May to early June for effective management of H. postica.
