도토리거위벌레는 큰턱을 이용하여 도토리에 구멍을 뚫고 가지를 자르는 독특한 행동을 한다. 이러한 행동을 이해하기 위해 다양한 현미경을 이용하여 구기의 해부학적 특징을 관찰하였다. 실체현미경을 이용한 연구에서는 도토리거위벌레 수컷의 평균 내전건과 외전건의 두께는 각각 32.87 μm, 53.83 μm이었고, 암컷의 평균 내전건과 외 전건의 두께는 각각 40.81 μm, 75.55 μm이었다. 내전건과 외전건의 유의한 두께 차이로 인해 큰턱을 닫는 힘보다 벌리는 힘이 더 강하다는 것을 유추할 수 있다. 광학현미경을 이용한 관찰에서는 주둥이 안쪽에 위치한 내전건과 외 전건의 너비 차이와 큰턱 쪽에서는 원형으로 위치하며 두부로 갈수록 납작해져 두부 외피 안쪽에 근육으로 연결된다는 것을 확인할 수 있었고, 내전건의 위치와 모양의 변화에 대한 관찰을 수행하였다. 전자현미경을 통한 연구에서는 외전건이 내전건보다 더 굵으며 이로 인해 큰턱을 안쪽으로 당기는 힘보다 바깥쪽으로 밀어내는 힘이 더 크다는 것을 확인하였다. 관찰 결과를 바탕으로, 도토리거위벌레, 밤바구미, 왕거위벌레의 큰턱의 형태와 이빨의 위치 그리고 큰턱의 움직임에 대해 비교 분석하였고, 도토리거위 벌레가 보여주는 특징적인 행동은 해부학적/형태적 특징과 연관되어 있음을 확인할 수 있었다.

본 연구에서는 생태학적 관점에서 biomimicry를 생태모방으로 정의하며, 생태모방에 대해 다학적 분야에서 정의되 는 개념들을 비교하였다. 생태모방은 생물･생태특성에 대한 분류 및 조사･원리분석을 통해 얻어진 정보와 아이디어를 공학 및 기술 분야에 응용이 되는 개념으로 정리하였다. 또한 생물학, 생태학 및 공학적 관점에서 생태모방 연구와 기술개발을 진행하는 Biology Push(생물특성기반 생태모방)와 Technology Pull(기술문제기반 생태모방)방법을 비교하며, Biology Push를 생태학적 관점에서 시작하는 ‘생물특성기반 생태모방’, Technology Pull을 기술필요에서 시작하는 ‘기술문제기반 생태모방’으로 정의하였다. 생태모방 연구동향을 살펴보면 안정적이고 친환경적인 원천 재료를 생물･생태 특성에서 찾아 기술개발에 초점이 맞춰진 사례가 대부분이나, 앞으로 생태모방 연구주제가 생물･생태 특성에서 비롯된 아이디어에서 착안되어 시작될 수 있는 연구분야의 잠재력에 대한 무한성을 시사하고자 한다. 향후 지속가능한 발전에 기여할 수 있는 생물생태학적 기반에 근거한 더 많은 연구와 기술개발이 필요함을 제시하고 있다.

Sexual dimorphism of the mouthpart, antenna and mandible of the Cyllorhynchites ursulus in South Korea was studied with linear measurements. The mouthpart and antenna measurements were conducted with a stereoscopic microscope using 122 specimens (72 males and 50 females). Microscopic observation of the mandible were conducted with a Field Emission Scanning Electron Microscope (FE-SEM) using 103 specimens (73 males and 30 females). Results showed that the size difference between males and females was significant in the size of the mouthpart and antenna. On the other hand, we could not detect sexual size dimorphism in the microstructure of the mandible. The bivariate plots made by the result of Principal Component Analysis (PCA) and Discriminant Analysis (DA) showed a size dimorphism in the size of the mouthpart and the antenna between males and females. Based on our study, sexual dimorphism in the mouthpart and antenna exists in C. ursulus from the South Korean population, and this difference seems to be related to the behavioral differences between males and females.

This study investigated multidimensional body image, self-esteem, clothing benefits sought, and Body Image After Breast Cancer (BIABC) within surgical subgroups among breast cancer survivors. The study applied the questionnaire survey method and the main research was conducted through an online survey. The respondents included 207 breast cancer survivors between the ages of 30 and 59, each of whom received the Multidimensional Body-Self Relations Questionnaire (MBSRQ). Self-esteem, clothing benefits sought, examination, and demographic variables were measured using a 5-point Likert scale. The main results of this study are outlined below. For clothing benefit sought, six factors were formulated—pursuit of self-expression/social approval, function/health, compensation, femininity, fashion, and camouflage—and BIABC was defined by the four factors of body stigma/vulnerability, transparency, limitation and cancer concern. While MBSRQ and self-esteem did not show a statistically significant difference between groups differentiated by the surgical methods experienced, those who underwent mastectomies scored slightly lower than members of the other groups. Moreover, the reconstruction after mastectomy group showed the highest mean on self-expression/social approval, compensation, femininity and entire clothing benefits sought, followed by the lumpectomy group and mastectomy group. The lumpectomy group was found to have more positive BIABC than the mastectomy group. In particular, the mastectomy group showed a lower body stigma/vulnerability mean than the other groups. This study is meaningful in that it improves our understanding of the body image of breast cancer survivors and provides basic knowledge for developing products and marketing strategies for breast cancer survivors as consumers.

도토리에 구멍을 뚫고 가지를 자르는 도토리거위벌레(Cyllorhynchites ursulus, n=130)의 큰턱(mandible)의 외부형태 와 가지를 자르는 기작을 생체모방에 이용하기 위하여 분석을 하였다. 또한 큰턱의 외부형태와 자르는 기작비교를 위하여 비슷한 습성을 가진 밤바구미(Curculio sikkimensis, n=30), 왕거위벌레(Paracycnotrachelus longiceps, n=15)의 큰턱 외부형태를 분석하였다. 외부형태 분석을 위하여 각 종의 큰턱을 주사형전자현미경(SEM)으로 촬영, 도토리거위 벌레의 자르기 행동과 뚫기 행동은 영상 촬영으로 분석하였다. 도토리거위벌레는 큰턱을 좌우로 움직이며 3개의 톱니형태의 이(teeth)가 있으며, 밤바구미의 큰턱은 상하로 움직이며 2개의 톱니형태의 이가, 왕거위벌레는 좌우로 맞물리면서 씹는 움직임이며 톱니형태의 3개의 톱니형태의 이를 가지고 있다. 도토리거위벌레는 큰턱의 내·외전건 (adductor · abductor tendon)을 움직여 구멍을 뚫고 가지를 자르는 것으로 분석이 되었으며 외전건이 내전건보다 굵어 더 큰 힘이 바깥쪽으로 작용하는 것으로 분석되었다.

The objective of this study was to take a closer look at the clothing benefits sought by breast cancer survivors in Korea. A qualitative descriptive study was conducted, using the focus group interview. Data was collected from members of online breast cancer forum. 18 participants were breast cancer survivors who had mastectomy or lumpectomy in their 30s~50s. The data was analyzed using content analysis in order to identify significant themes. The analysis indicated that benefits were sought after functional/comfort, health, feminity, and compensation were found. First, breast cancer survivors considered functional/comfort to be most important benefit so as to keep the body comfortable from the weather. Second, participants put the healthy body as the first priority and chose a well-being lifestyle and were likely to wear clothes made in healthy fabric, such as organic, bamboo or charcoal. Also, they preferred to look active by wearing sport brands or outdoorwear brands. Third, after the surgery, they experienced the sense of femininity loss and the sense of crisis as a woman. Single women and married women in early 30s recognized more seriously, and they tried to recover feminity by wearing clothes with feminine details. Forth, breast cancer survivor consumers tended to shop for the psychological compensation. In summary, consumers with breast cancer surgery, unlike general healthy women, did not sought to be economic, fashion, self-expression benefits, rather they sought health, femininity, and compensation benefits. Therefore, it seems necessary to develop proper products and marketing strategy to meet the said consumer's special needs.

The purpose of this study was to examine the outdoor sportswear purchase behavior, outdoorwear sportswear brand preference, functional fabric awareness, and benefits sought. The research was performed through in-depth interview during February to March 2011. Data were collected from 10 consumers who had purchased outdoor sportswear and experienced camping in 6 months. First, the results from study showed that functionality/comfortability, design, color, and brand name were important factors in selecting outdoor sportswear. Offline stores were the main place to purchase, however, internet shopping mall and portal online community were another shopping channel as well. Second, respondents preferred imported outdoor sportswear brand to national brand. According to the study, the respondents trusted the imported outdoor sportswear quality based on the brand name, value, and brand history more than national brand. Third, consumers who had low functional fabric awareness were more likely to evaluate apparel products based on the brand name. Knowledge levels for textile functions were high in elastic, UV protection, air permeable, and antibacterial properties. The essential features for camping were water absorbing and quick dry, water resistance, wind proof, UV protection, and fire retardant properties. Finally the results showed that there were two sportswear benefit soughts: functionality and status ostentation.
