Four new species of the genus Alloclubionoides collected from mountain litter and hillock litter around the agricultural ecosystem of Korea are described in the present work with appropriate body measurements and morphological illustrations; A. hwaseongensis sp. nov., A. imi sp. nov., A. namhansanensis sp. nov. and A. nasuta sp. nov. Females of A. hwaseongensis sp. nov., A. namhansanensis sp. nov. and A. nasuta sp. nov. can be distinguished based on the epigyne shape and structure of internal genitalia from previously described species. Males of A. imi sp. nov. can also be distinguished based on the shapes of retrolateral tibial apophysis, embolus tip and conductor from previously described species. Also, a key to the Korean Alloclubionoides spiders is provided. Alloclubionoides gajiensis Seo, 2014 is newly synonymized with Alloclubionoides cochlea (Kim et al. 2007).

한국고유종인 밭고랑거미과의 봉화밭고랑거미Agroeca bonghwaensis (Seo, 2011) 수컷을 측정치 및 형태학적 도해와 함께 처음으로 기재한다. 봉화밭고랑거미의 수컷은 A. brunnea (Blackwall, 1833) 수컷의 더듬이다리기관과 유사하나 끝부분이 뭉뚝한 후측면돌기와 기부가 넓고 끝부분이 넓은 갈고리 모양의 중부돌기로 쉽게 구분된다.

Gender has been considered as a very important factor in influencing the effectiveness of sex appeal advertising, yet only biological sex (male or female) has been examined. Therefore, this paper aims to examine the role of gender identity (masculinity, femininity or androgynous) in how people respond to sexual appeals in advertising. By studying the influence of this variable, present research would help in building a more comprehensive picture of why people respond to sexual appeals as they do.

Food web of main arthorpods in 3 differently managed rice fields (low input, duck, apple snail farming) was investigated in Hongseong area, Chungcheongnam-do, Korea. Main arthropods were selected by their abundance during the rice growing season in 2010. Food web was analyzed with stable isotope, δ15N and δ13C according to rice growth satges (seedling, tillering, booting, blooming/heading, and ripening stage). Rates of δ15N and δ13C in soil (F=5.72; df=2, 6; P=0.0407, F=40.86; df=2, 6; P=0.0003, respectively) and δ13C in rice (F=6.46; df=2, 6; P=0.0319) were statistically different. Rate of δ13C in Lissorhoptrus oryzophilus (F=9.50; df=2, 6; P=0.0138), Pirata subpiraticus (F=11.00; df=2, 6; P=0.0098), and Pachygnatha clercki (F=6.33; df=2, 6; P=0.0333) were statistically different among farming methods. Stable isotope structures in food web were slightly different among 3 farming methods seasonally. Rates of δ15N and δ13C of rice pests such as Nephotettix cincticeps, Nilaparvata lugens, Laodelphax striatellus, and Sogatella furcifera were related to rice plant. Those of Tomoceridae sp. and Chironomidae sp., however, were not related to rice plant. Spiders as main natural enemy group were ranked on the top of food web and were thought to have life cycle based on the rice field from stable isotope structure.
