  • Tomato hypocotyl can generally be one of two colors, purple or green. Genetically, this trait is controlled by a single dominant gene. Hypocotyl tissue specific color expression is one of many visible genetic marker sources used to select tomato progeny. However, the visible marker does not show a clear distinction between homozygous genotype and heterozygous genotype from the breeding lines. Therefore, to identify a hypocotyl pigmentation related marker, we screened DNA polymorphisms in thirteen tomato lines showing purple or green hypocotyls. The markers used for screening consisted of primer set information obtained from anthocyanin related genes, conserved ortholog set II (COS II) marker sets localized near anthocyanin related genes, and restriction fragment length polymorphism (RFLP) markers localized near COS II markers, which produce polymorphisms between purple and green tomatoes. One primer from a RFLP fragment resulted in a polymorphism on agarose gel electrophoresis. From the RFLP fragment, a cleaved amplified polymorphic sequence (CAPS) marker was developed to distinguish between purple and green hypocotyls. The genotypes of 135 $F_2$ individuals were analyzed using the CAPS marker, and among them, 132 individuals corresponded to the phenotypes of hypocotyl pigmentation.

  • In order to study for the growth of fish in the aquaculture industry, the behavior analysis of rock bream (Oplegnathus fasciatus) depending on the temperature and LED lights was conducted. In this study, water temperatures from 10 to 30 degrees were used. One red light (wave length: 622 nm; light power: 811 mW) and one green light (wave length: 518 nm; light power: 648 mW) were used. Behavior of the rock bream was analyzed at an average moving distance for one minutes (AMD) and a rate of movement. The mean AMD were respectively 5.3 m, 7.3 m and 3.0 m in the red LED light, green LED light and control condition. The mean rates of movement were 77%, 88% and 61% respectively in the red LED light, green LED light and control condition. The mean AMD during 24 hours were 3.1 m, 3.1 m and 3.3 m respectively in the red LED light, green LED light and control condition.

  • China has achieved remarkable economic growth through an extended period of rapid industrialization. However, adverse environmental issues have become more prevalent during this time of development. In particular, car exhaust emissions in the country have become one of the most substantial causes of environmental degradation in China. To combat these issues, the Chinese government is actively implementing green car policies to mitigate the negative environmental concerns. Likewise, Chinese consumers' interest in green cars has also increasing. Despite these changes in consumer perceptions, research on Chinese consumers' green consumption behavior is still in its infancy. Therefore, an empirical study was conducted to measure the relationship between zhongyong(中庸) values, new ecological paradigm(NEP), and green consumption behavior for 334 Chinese consumers. As a result, the study found that the three sub-dimensions of zhongyong(中庸) values(multi-dimensionality, flexibility and compatibility) and NEP had a significantly positive(+) effect on the purchase intention of green cars. It was also found that NEP positively mediates the effect of flexibility and harmony on purchase intention of green cars. This study is expected to provide academic outcomes on China, which is currently the world's fastest growing green car market, as well as providing practical strategic implications for establishing unique green marketing strategy for China.

  • 현재 녹지 연결성 조사는 대부분 현지조사에 의존하고 있어, 특정시기의 특정지점에서 조사된 결과에 주안점을 두고 있다. 그리하여 조사지점의 대표성에 한계가 있고 많은 시간이 소요되고, 조사 대상물 위치의 부정확, 경제적 비효용 등이 문제점으로 지적되어왔다. 본 연구는 이러한 문제에 대한 대안을 제시하기 위해 Landsat TM (Thematic Mapper) 영상의 픽셀에 의거한 녹지 연계망을 평가하고자 출발하였다. 그리하여 원격탐사 기법이 녹지 연계망을 평가할 수 있는 도구로서의 가능성을 지니고 있는 지를 평가하고자 특정 사례 연구지역에 대해 실증적인 연구가 수행되었다. 조사지점에만 국한된 현지조사 방식과 달리 픽셀 기반의 평가는 광역적인 녹지 연계망의 분포실태를 단시간에 제시하였다. 녹지 연계망 훼손 추세 평가는 다양한 시기의 녹지 변화 실태를 정량적으로 제시하고 있기 때문에 그 결과가 녹지 연계망 보전과정에서 설득력을 지닌 근거자료로 활용될 수 있을 것으로 판단된다. 본 연구가 녹지 연계망 감시에서 객관적인 데이터에 의거한 정책결정이 아닌 직관에 의존하여 왔던 관행을 개선될 수 있는 계기가 되어 향후 녹지 연계망 보전관련 중요한 참고자료가 될 수 있을 것으로 사료된다.

  • Japan has been tried to integrate Western planning theories into its parks and green systems in the past. However this effect has been regarded unsuccessful. One of reasons for this is that the green systems have been treated as an urban facility, instead as systems. Another reason has to deal with greenbelt's stationary and reservation characteristics that make difficulty to respond timely to the rapid urbanization. The parks and green systems in Korea was introduced in 1990 and began to be promoted fully with the 'Parte and Green Master Plan' established in 2005. However, due to its short history, incomplete aspects exist in its philosophy and methods for promoting the system. Based on these experiences, the current green zone plans in Japan considers the green structure as an independent institution and amenity plan, not a tool of urban planning, that can be a medium for realization of urban visions. And main characteristics of this approach are 1) classifying the green structure into four categories in order to respond to urban forms and purposes, 2) pursuing confirmity with urban planning, and 3) executing the landscape plan based upon core green areas. From reviews upon experiences of Japan as well as considerations on demands and conditions of green systems in Korea, we proposed the following five new strategies for the construction of the urban parte and green system in Korea. They are 1) to develop urban parks and green systems into a genre of urban development improving the quality and local competitiveness of cities rather than a means of urban planning; 2) to form the integrated structure of urban green zones; 3) to transform the urban parte and green systems into practical systems as the centers of localities; 4) to raise criteria for planning and execution plans for effective implementations of the urban parte and green systems, and 5) to provide specific guidelines for the construction of urban parks and green systems through organizing research groups or specialists.

  • This study was carried out to investigate the effects of mowing height, rolling, N-fertilizing, and season on green speed(i.e., ball-roll distance) for developing and implementing a program of increasing green speed in Korean golf courses. Data were subjected to multi-regression analysis using SPSSWIN(Statistical Package for the Social Science), which collected from Yong-Pyong golf course greens selected to investigate. The results was as follows. 1) The multi-regression analysis of mowing height, rolling times, and N-fertilizer application rates on spring green speed was as follows; $Y_1$(spring green speed)=4.287+0.155X$_1$(rolling times)-0.131X$_2$(the amount of N-fertilizing)-0.251X$_3$(mowing height). 2) The multi-regression analysis of mowing height, rolling times, and N-fertilizer application rates on summer green speed was as follows; $Y_2$(summer green speed)=4.833-0.423X$_3$(mowing height)+0.146X$_1$(rolling times)-0.107X$_2$(the amount of N-fertilizing). 3) The multi-regression analysis of mowing height, rolling times, and N-fertilizer application rates on fall green speed was as follows; $Y_3$(fall green speed)=4.651-0.383X$_3$(mowing height)+0.142X$_1$(rolling times)-0.103X$_2$(the amount of N-fertilizing). 4) As mowing height was lowered by 1mm, green speed increased by 0.251~0.423m. As rolling times increased by 1(one), green speed increased by0.142~0.15m. As the amount of N-fertilizing increased by 1g/$m^2$, green speed decreased by 0.103~0.131m. The season also affected green speed. In comparison with spring green speed, summer green speed decreased by 0.145m and fall green speed decreased by 0.144m.

  • The purpose of this study was to examine the importance of eco-friendly design elements related to residential space by residents and what element they prefer. To achieve this, 18 eco-friendly design elements related to residential space were selected from the Green Building Certification Criteria and the relevant research papers. These elements were categorized into four areas; the ecological environment area (4 elements), the indoor environmental climate one (4 elements), the energy and resource saving one (6 ones), and the material one(4 ones). On the base of these 18 elements, the importance degree of each element was examined by using 5-point Likert scale. The subjects were 299 housewives living in apartment houses in Jangyu new town, Gimhae. The subjects perceived strongly the importance of eco-friendly design elements, but many of them did not know about Green Building Certification Criteria. Overall importance of 18 elements by the residents was very high. Also, the indoor environmental climate area was considered as the most important one, followed by the energy and resource saving area, the material area, and the ecological environment one.

  • Intact phycobilisomes from a wild-type red Chondrus crispus and its vegetatively derived green mutant were isolated by centrifugation through a discontinuous sucrose density gradient. Pigment composition was subsequently characterized by spectrophotometry. Vegetative thalli of the two strains grown together for six months in the laboratory resulted in different pigment profiles. Two pigmented phycobilisome bands appeared in the sucrose gradient of the wild-type alga, a purple coloured one, and a pink one, whereas only a single blue band appeared in the gradient of the green mutant. Spectrophotometric and fluorescence analyses identified the phycobiliprotein composition of the purple band as the typical phycoerythrin-phycocyanin-allophycocyanin complement in the wild-type, but there was no detectable phycoerythrin present in the blue band of the green mutant. Sodium dodecyl sulphate, preparative polyacrylamide gel electrophoresis analysis confirmed the presence of allophycocyanin subunits in all extracts, but firm evidence of an R-phycoerythrin linker polypeptide in the blue band was missing. These results highlight the ability of C. crispus to adapt to a phycoerythrin deficiency by adjusting light harvesting pigment ratios.

  • Two one-month-old dairy calves which have Eimeria oocysts in their bloody diarrhea died acutely a few days after showing the first clinical signs. At necropsy, hemorrhagic and congestive gastrointestinal organs were observed in both calves, and abomasal ulcerations existed. As a prevalent agent in all of the collected intra-intestinal specimens, Clostridium perfringens was isolated and the strain was identified as type A possessing alpha and beta2-toxins. In these clinical cases, intercurrent infection by C. perfringens type A and Eimeria through contaminated environment may be responsible for acute hemorrhagic enteritis.
