Smart healthcare clothing combines IoT, new technology, and clothing construction to perform specific care functions, and its utility has been expanding rapidly within aging and diversified societies. However, the related market remains at an early stage of development due to limited regulation, lack of consumer awareness, and the need for not only technical development but promotion plans for potential users. This paper aims to analyze factors influencing purchase intention for smart healthcare clothing with biosignal monitoring, including variables in the Technology Acceptance Model (TAM), clothing attributes, health-related lifestyle factors, and fashion innovativeness. A survey was conducted on a sample of 300 males and 300 females ranging in age from 20 to 50 years, and data were analyzed using SPSS 21.0. The results show that perceived usefulness, perceived aesthetic attributes, health responsibility, and fashion innovativeness were overall significant predictors of using smart healthcare clothing. Additionally, perceived ease of use and physical activity in the male subsample, and perceived compatibility within the female group, also had significant effects. Furthermore, age was a determining factor; for subjects in the 30s age group, perceived usefulness, compatibility, and health responsibility had significant positive associations. The results of this study can provide basic guidelines for designing merchandising plans to expand user acceptance of smart healthcare clothing.

Bursaphelenchus sinensis was first found in Austria from the wood packaging material imported from China. In Korea, B. sinensis was detected from dead branches of Pinus densiflora located in Jinju, Gyeongnam province. Morphology of B. sinensis was characterized by unique male spicule with weak rostrum and squared condylus, and female with small vulval flap and conical shaped tail. Genomic DNA of B. sinensis was extracted and ITS region was fully amplified by PCR. ITS-PCR product was analyzed by RFLP and also directly sequenced. Polymorphism by RFLP-ITS was matched with that of B. sinensis and ITS sequence data was identical to B. sinensis information in GenBank. The Korean isolate of B. sinensis, Bs-Jinju, was submitted to GenBank and acquired the accession number, #MG934676. Host pathogenicity of B. sinensis was tested by artificial inoculation of nematode (30,000/ sapling) on 5-year-old P. densiflora. There were no disease symptoms in all tested pines inoculated by B. sinensis, whereas 100% mortality showed on pine saplings by B. xylophilus inoculation. This is the first report of B. sinensis in South Korea.

재선충속(Bursaphelenchus) 선충의 식물 기주체내 증식 능력 및 병원성을 비교하기 위하여 선충 3종 (이하 Bursaphelenchus xylophilus: Bx, B. mucronatus: Bm, B. thailandae: Bt)과 해송(Pinus thunbergii), 잣나무(Pinus koraiensis) 2종을 실험에 사용하였다. 5가지 선충 처리 조합 (①Bx+Bt, ②Bx+Bm, ③Bx+Bt+Bm, ④Bt+Bm, ⑤Bm)으로 한 본당 10,000마리씩 접종 한 후 7주 동안 외부 병징 및 선충 밀도를 조사하였다. 그 결과, Bx가 포함된 대부분 처리구에서는 5주 차에 전체 고사가 진행 되었고, Bx가 포함되지 않은 처리구는 병징이 나타나지 않았다. 예외적으로, Bx+Bm, Bx+Bt+Bm 해송 처리구에서는 7주 후에도 전체고사가 나타나지 않았다. 이 경우 선충 밀도 조사 결과, Bm이 약 42%를 차지하였으며, 이는 소나무재선충병의 병징 발현을 약화를 유도하는 역할을 하는 것으로 추정된다. 모든 처리구에서 Bx의 밀도가 가장 높았으며, Bt는 전혀 검출되지 않았다.

소나무재선충과 근연종인 Bursaphelenchus 속 2종간의 매개충 채내 침입력과 경쟁력을 비교 실험하였다. 공시충은 Bursaphelenchus xylophilus (이하 Bx), B. mucronatus (이하 Bm), B.thailandae (이하 Bt) 선충 3종과 솔수염하늘소 (Monochamus alternatus)와 북방수염하늘소 (M. saltuarius) 2종을 사용하였다. 매개충 번데기에 선충 3종을 10,000 마리씩 단독 또는 혼합접종을 하고, 우화 후 체내 선충 개체수를 조사한 결과, 솔수염하늘소에서는 Bx, Bm, Bt가 각각 2,283마리, 1,575마리, 3,083마리로써 Bt의 침입력이 가장 높게 나타났다. Bx+Bt 처리 시에는 Bx 24%, Bt 76%, Bx+Bm 처리 시, Bx 68%, Bm 32% 비율로 조사되어 Bt>Bx>Bm 순으로 침입력이 강한 것이 확인되었다. 북방수염하늘소 에서 Bx, Bm의 침입력을 비교한 결과 Bx는 2,120마리, Bm 1,730마리로 솔수염하늘소에서와 유사한 결과를 나타내었다. 이로써 선충 종간 침입력은 다양하며 이는 매개충 종과는 무관함을 알 수 있다.

The purpose of this study was to investigate the differences in various fashion lifestyle segments’ perceived benefits and design preferences for outdoor clothing to improve the development of outdoor clothing. Data were collected by questionnaire from 600 subjects aged 30 years and over with experience purchasing outdoor clothing in the past year. Frequency analysis, factor analysis, cluster analysis, reliability analysis, ANOVA, and chi-square analysis were used for the data analysis. The results of this study were as follows. Four segments were identified based on fashion lifestyle: manifoldly conscious, sensation conscious, practicality conscious, and brand conscious. Perceived outdoor clothing benefits generated three dimensions, including premium brand, practicality, and functionality, and preferred image produced two factors, tasteful/refined and comfortable/casual. Significant differences were found in the purpose of purchasing outdoor clothing, perceived benefit, and image and t-shirt pattern design preference among the segments. The manifoldly conscious group had a higher tendency to pursue various benefits and images of outdoor clothing and to prefer t-shirt textile designs with foulards and stripes. The sensation conscious group considered fashion and individuality in daily life but not in outdoor clothing. The practicality conscious group showed a preference for simple and casual styles with functionality and foulard patterns for t-shirts. The brand conscious group tended to prefer a striking design to functionality. This study is expected to be used as preliminary data for merchandising planning of outdoor clothing.
