This study examined the seasonal, regional distribution of mosquito vectors related with disease vectors in the Jeju. From March to November, sample were collected from 11 points in four environmentally different sites in Jeju Island. Samples were collected twice a month using a black-light trap and a BG sentinel trap. Overall, five genera and seven species types of 6,042 female mosquitos were collected. Among the collected mosquitos, 4,159 (68.8%) and 1,348 (24.4%) were Culex pipiens and Aedes albopictus, respectively, making them the dominant species. Additionally, collection using the black light trap produced 72.8 entities per trap in Jungang-dong service center in the center of the city, which was the highest value, while the lowest amount of 1.4 per trap was recovered from the airport. When the BG sentinel trap was used, the largest recovery was observed in the port, where there were 71.7 entities per trap, while the lowest amount of 28.3 entities per trap was recovered at Gealmae Eco Park. The overall number of mosquitoes collected started to increase from May, and reached the largest value of 1,156 (19.1%) in August. Trapped mosquitoes are created 364 pools of up to 50 grains per pool, by season, by environmental, and by species. When the pools were used, no flaviviral infection was observed upon real time RT-PCR.

Although 'the International Ship Registration Act' has been enacted in Korea as of 1997, its effect is still in question to make shipowners and operators flag in or reflag because of insufficient incentives for them. Therefore, 'the Special Law for Jeju Free International City' has been established and the system of 'Special Ship Registration Zone' has also been enforced. Despite this, few studies were carried out to measure the relative importance of factors for Jeju International Ship Register yet. Against this backdrop, the purposes of this study are firstly, to investigate a relative importance of Jeju International Ship Registration System using AHP(Analytic Hierarchy Process) and secondly, to compare the characteristics of Flags of Convenience(FOC) with International Ship Register(ISR) which was adopted by several Far East Asia Countries(e.g., China, Hong Kong, Chinese Taipei and Japan). Moreover, this study aims to compare FOC with ISR in terms of shipping policy, ship management, and expenses and tax policy. In this paper, the factors were constructed with four high levels consisting of twenty one low levels to evaluate Jeju International Ship Register by utilizing Expert's brainstorming and AHP. According to the results, it is critical to expand the exemption and tax-related expenses, and also manage foreign-related systems systemically. This study provides important implications to maintain the tonnage tax system for ships effectively as well as to intensify the competitiveness of Jeju International Ship Register System.

Geophysical exploration using electric resistivity, ground penetrating radar (GPR), and impedance high-frequency (ZHF) surveys was conducted in Gujwa-eup, Jeju City, Jeju Island, an island in the Korea Strait, to confirm the existence of new caves near known caves. The exploration revealed a number of anomaly zones, presumed to be caves; 27 sites at suitable locations and depth ranges were selected for drilling and further surveys. However, contrary to predictions, most of the anomaly zones were clinker layers or paleosols intercalated with lavas. Only five boreholes intersected caves. The clinker layers and paleosols were possibly detected as anomalies owing to their different physical properties from the other rocks. Two of the five cave-finding boreholes penetrated Yongcheon Cave; a new cave was found at the other. The two boreholes that penetrated Yongcheon Cave were drilled in areas where the cave has not been previously reported, and thus helped correct an error in the cave distribution map. The cave newly discovered in this boring exploration is 180 m long, and it is connected to the upstream part of Dangcheomul Cave (110 m). The cave contains well-developed lava helictites, lava levees, and ropy structures; carbonate speleothems such as soda straws, stalagmites, columns, and curtain shawls are also well preserved. Notably, the unique shape of the carbonate speleothems is attributed to their growth in relation to the cavern water that flowed into the cave along plant roots.

This study applies two-choice model to identify the major determinants of NIMBY attitudes when a large-scale composting facility is built around a residential area. Using a survey data of residents in Jeju City, Korea, logit estimation is implemented. The empirical results are consistent with the implication of the specified model: a representative resident's NIMBY attitude is positively (negatively) affected by "Negative Neighborhood Characteristic Variables" ("Positive Wealth Attribute variables"). Socio-demographic variables may be summarized as mostly statistically insignificant, which implies that policy makers may have to take into consideration their region-specific socio-demographic factors instead of simply emulating the policies which have been successful elsewhere.

The aims of this study are to develop a STEAM program focused on the appearances of birds' beaks and insectivorous plants and to identify its influence on elementary students' basic scientific process skills, creative problem solving ability and affective domain. For these objectives, the STEAM program was developed by reorganizing contents of the appearances of animals and plants in the units of 'Life of Animals' and 'Life of Plants' from 2009 revised national science curriculum for 3th and 4th grades. The developed STEAM program was applied to twenty nine 3th grade students of J elementary school located in S city. As a result of applying the STEAM program, the experimental group in this study showed significant improvements of the creative problem solving ability, scientific process skills and affective domain compared to the control group's scores. Therefore, development studies on STEAM programs integrated different science fields using animals and plants could be meaningful works to encourage elementary students' skills and interest.

In this study, characteristics and trends of tropical night (TN) are investigated by using the KMA 14 observation data for the recent 50 years (1958-2007) over South Korea. The TN is defined as a day with a daily minimum temperature exceeds the absolute threshold temperature ($25^{\circ}C$), and the relative deviation from normal temperature, 95th percentile of all observed daily minimum temperature. Although the spatial distribution of TN occurrence depends on the choice of the definitions, the frequency of TN shows strong spatial and interannual variations with the minimum at high land area (Chupungnyeong and wet years) and maximum at southern coastal area and large city area (Jeju, Busan, Seoul, Daegu). Most of TN occurs in August (56%) and July (41%), and the duration date of TN is proportional to the frequency of TN without regard to the definition method. In general, increasing trends are found in the TN time series without regard to the analysis method, but the trends are clearly depending on the analysis period and geographic locations. Decreasing trends are prominent during the most of analysis period, especially until the mid of 1990, whereas strong increasing trends are found during recent 30 years (1988-2007), especially at Jeju, Ulsan, Daegu and Pohang. Also the severity of TN is significantly increased in recent years.

We investigated perceptions and image analysis on scientists studying small organisms reflected in elementary student's drawing using a modified version of the Drawing-A-Scientist-Test. The participants were 530 of fifth and sixth graders consisted of 449 ordinary students and 81 science gifted students. The data were collected from associated words, images and explanatory notes depicted by students engaged in questionnaires. The results indicated that a larger number of students reminded small sized animals and/or plants as words associated with small organisms. In addition, some students depicted anthropomorphic or abstract microorganisms. In this study, more stereotypes of scientists' appearance were exhibited at sixth graders and city region group. Most of the students depicted indicators such as lab coat, glasses, scientific instruments for observing, indoor, male and young, whereas only a few students depicted collaborative work. There was statistically significant difference between girls and boys, because boys perceived male scientists only, while half of girls depicted female. More frequent research instruments and scientific captions were used when science gifted students depicted scientists studying small organisms. These results could be contributed to education on microorganisms in elementary science.
