This experiment was conducted to determine the most effective type of Bight·trap for pine catepillar moths (Dendrolimus spectabilis B.) and to investigate the environmental factors affecting the attractiveness of the moths.. The various types of light traps made used of: black light, white light, fluorescent light, yellow light, and red light and the environmental factors considered were rainfall, wind velocity and collecting time. All the traps were operated from 8 in the evening to midnight. The results obtained are summarized as follows; The most effective attraction of moths ($62\%$ of total number attracted) was observed with blacklight-lamp and the most abundant attraction of the moths was found from 8 to 10 in the evening. Attractiveness in terms of sex ratio attracted from 8 to 10 in the evening was found to the .approximately 7 female to 1 male, Environmental factors considered were found to have no influences in attractiveness of the moths in this experiment.

Sex pheromone blends of large black chafer, Holotrichia parallela (Motschulasky), which consist of a major component L-isoleucine methyl ester (LIME) and a minor component (R)-(-)-linalool, showed different attractiveness depending on the mixing ratios of the two components in potato fields in South Korea. The best ratio for H. parallela attraction was 2.5:1 of LIME and (R)-(-)-linalool. The attraction ability of pheromone traps bated with 2.5:1 ratio did not drop up to 14m, but significantly decreased at 21m from H parallela release point. Korean population of H. parallela showed almost same periodical activity to sex pheromone with that reported in Japan, which showing a circabidian periodicity of 48h cycle.

This study investigates the needs of cruise tourists for building customer oriented ubiquitous tourism services. Through the field survey, the relationship between cruise tourism motivations and ubiquitous cruise services were analyzed. In this study, cruise tourism motivations mean destination attraction, family friendship, socialization, education/novelty and escape from daily routine. And ubiquitous cruise services are consists of boarding service, security service, safety service, customization service, and payment services. The results are as follows; cruise tourists with more socialization motivation get more use intention of ubiquitous payment service; cruise tourists with more destination attraction have more use intention of ubiquitous customization service.

In the Republic of Korea, many of the wooden architectural heritage are located in forests and, therefore, are vulnerable to termite damage. In Korea, the predominant approach to termite control involves chemical control methods using termiticides. The rapid attraction of termites to termiticides is essential to shorten the control period. The current study investigated the attraction of Korean termites to carbon dioxide and the appropriate concentration of carbon dioxide required for effective attraction by conducting a basic experiment on the attracting effect in the underground environment. The results showed that carbon dioxide is effective for attracting termites, and an effective concentration range of 10% or less was selected. Additionally, this study established the potential and applicability of carbon dioxide as an attractant in the control of subterranean termites. Future studies should aim at conducting field studies on the application of carbon dioxide to improve the termite control effect, particularly in preserving wooden architectural heritage.

This paper reports about the development of scanning probe microscopy (SPM) tip with multi-walled carbon nanotube (MWNT). For making a carbon nanotube (CNT) modified tips, AC electric field which causes the dielectrophoresis was used for alignment and deposition of CNTs to the metal coated SPM tip. By dropping the MWNT solution and applying an electric field between an SPM tip and an electrode, MWNTs which were dispersed into a diluted solution were directly assembled onto the apex of the SPM tips due to the attraction by the dielectrophoretic force. In this paper, we investigate experimental conditions about the alignment of the CNT to tip axis according to the change of the angle between a tip and an electrode. Experimental results are presented, and then fabricated CNT tips are showed and measurement results for 15nm gold particles are compared with that of the conventional silicon tip.

The purpose of this study was to analyze the design trend of the vertical garden design in the indoor space through the examples of green wall in the lobby space. For the analysis, this study looks into the 'Guide for the Building Greening System' to understand the technical consideration for the green wall. After that, the key design elements was drawn from existing green walls through the literature review and field survey and field-survey. The study picked six green walls which was completed after 2000 in the lobby space in Seoul. The major findings of this study were as follows: First, the design factors mainly depend on the plant selection, which leads to the outlook and texture of the vertical walls. The texture is expressed by the two-dimensional or three-dimensional planting methods which is related to the selection of plant species. Second, the vertical walls in the lobby area should be planned for the function of space which could be transition, human traffic, mood and attraction. Third, the vertical wall should be integrated with the surroundings in order to reinforces the dynamic or static space experience.

Overwintering sites and Seasonal occurrence of various growth stage of the rice black bug, Scotinophara lurida BURMEISTER were studied at the rice paddy field in Chungbuk area, from 1999 to 2001. Attraction by light trap from overwintering site of overwintering adults occurred from early June to mid July and its peak was shown on late June. Eggs were oviposited from early July to early August and its peak appeared in late July. Nymphs were observed from mid July to late September with its peak on mid August. The newly eclosed rice black bugs were found in late August and its peak on mid September. The rice black bug overwintered as adult at mountain foot, banks, and rice paddy levee.

We report a simple, low cost, and reliable method for assembling a multi-walled nanotube (MWNT) to the end of a metal coated scanning probe microscopy (SPM) tip. By dropping the MWNT solution and applying an electric field between an SPM tip and an electrode, MWNTs which were dispersed into a dielectric solution were directly assembled onto the apex of the SPM tip due to the attraction by the dielectrophoretic force. The effective measurement of a MWNT -attached SPM tip was demonstrated by direct comparison with AFM images of a standard sample with a bare AFM tip.

In this study we present a new approach for computing the partial atomic charge derived from the wavefunctions of molecules. This charge, which we call the "y_charge", was calculated by taking into account the energy level and orbital populations in each molecular orbital (MO). The charge calculations were performed in the software, which was developed by us, developed using the C# programming language. Partial atomic charges cannot be calculated directly from quantum mechanics. According to a partitioning function, the electron density of constituent molecular atoms depends on the electrostatic attraction field of the nucleus. Taking into account the Boltzmann population of each MO as a function of its energy and temperature we obtain a formula of partial charges.

For the selection of attraction industry of foreign investment in the free trade zone of Gwang Yang Bay, an overall consideration should be made considering aspects such as the industry development strategy of Gwang Yang Bay and the regional industry development strategy of the local government. For Gwang Yang Bay to grown into the E-Hub Port of Northeast Asia, the development of the back zone of should be accelerated. There is a need to offer custom made incentives for the core businesses. Packaging is a field of combined science and a future industry. Packaging industry, which has close association with regional industry and regional college's research human resources, should be combined with design and set up a packaging industry complex.
