The purpose of this study was to investigate the perception and preference on textile design specially on bedding products which are widely interested in the life-style market. The study was carried out targeting to 250 women between the ages of 20s and 40s based on the four seasons. The collected data was processed with SPSS 21.0 program using frequency, cross tabulation, and ANOVA analysis. The results were as following. There were slight differences on the results of the study including purchase behavior and preferred bedding textile design: color, color tone, and pattern on the textile design of bedding products according to age and season. Most of age had similar color preference on the bedding products in the season but a slight different between fall and winter. However, as color tone and pattern on the textile design of the bedding products were concerned, there were significant difference between the age depending on the season. There were significant differences of color tones and patterns in fall and winter, but not significant in spring and summer. Therefore, the domestic market of the bedding products needs more various textile design development according to consumers' preference and seasonal trend which should be discriminated in order to increase product competitiveness.

Monthly distributions of fishing boats at night in the East Sea are described, using defense meteorological satellite program (DMSP)/operational linescan system (OLS) images and common squid (Todarodes pacificus) catches data. We also estimated temperature in 50m, which is main catch depth of the squid, by MCSST (multi-channel sea surface temperature). We examined DMSP/OLS, MCSST and other observation data from 1993 to 2000. We assumed that squid were caught in areas where fishing boats were located. Fishing boats at night appeared only near the Korea/Tsushima Strait from January to March. Fishing boats moved to the northward from April to Jun, distribution of fishing boats in spring appeared greater than those in winter. In summer (July-September), center of fishing grounds was formed near the Uleung Island in the south east coast of Korea. The north-south distribution range of fishing boats in October appeared to be greater than that in other months. In particular, we estimated main season of squid catches based on distribution range reflecting the number of fishing boats of north-south and east-west directions from September to December. Relationship between satellite estimate SST and in situ SST showed high correlation (0.91). The correlation between the SST and 50m depth temperature, estimated based on the satellite SST, was relatively high in February, April and October.
KMA performed the special observation program to provide information about severe weather and to monitor typhoon PRAPIROON using the ship which called the Gisang 1 from 29 June 2018 to 4 July 2018 (UTC). For this period, upper-air was observed 21 times with 6 hour intervals using rawinsonde in the Gisang 1. We investigated the impact of upper-air observation data from the Gisang 1 on the performance of the operational convective scale model (we called LDAPS). We conducted two experiments that used all observation data including upper-air observation data from the Gisang 1 (OPER) and without it (EXPR). For a typhoon PRAPIROON case, track forecast error of OPER was lower than EXPR until forecast 24 hours. The intensity forecast error of OPER for minimum sea level pressure was lower than EXPR until forecast 12 hours. The intensity forecast error of OPER for maximum wind speed was mostly lower than EXPR until forecast 30 hours. OPER showed good performance for typhoon forecast compared with EXPR at the early lead time. Two precipitation cases occurred in the south of the Korean peninsula due to the impact of Changma on 1 July and typhoon on 3 July. The location of main precipitation band predicted from OPER was closer to observations. As assimilating upper-air data observed in the Gisang 1 to model, it showed positive results in typhoon and precipitation cases.

In this study, water quality levels were classified and water quality indices were calculated and analysed by using the water quality components of living environmental standards monitored 10 years (2008 ~ 2017) at four stations in the West Nakdong River. As a result of analyzing the monthly variation of the water quality components of the living environmental standards, the water quality in the West Nakdong River was worse downstream than upstream, and pollution at the WNR3 located in the downstream of the Jomangang was the most serious. As a result of classification of water quality levels, BOD and COD levels were the lowest, so water quality pollution in the West Nakdong River was found to be highly influenced by organic matters. The water quality index was the lowest in July and August at four stations, so water quality is showing the worst in summer. As a result of analyzing the correlation between the water quality components and the water quality index, the correlation between the TOC and the water quality index was high in the four stations, and the water quality index in the West Nakdong River was dominated by organic matters and nutrients.
The taxonomic sufficiency approach has been proposed as a surrogate for the typical analysis of species-abundance data, especially in conditions involving prominent pollution gradients. Here, we evaluate the use of taxonomic sufficiency with infralittoral macrobenthic data derived from samples taken in a moderate polluted subtropical environment in southeastern Brazil, analysing five taxonomic levels and including two functional levels throughout polychaete feeding guilds and trophic groups. The data were collected seasonally at nine stations and studied for two abundance data series (0.5 and 1.0 mm sieve mesh-size). The results showed a similar ordination pattern between the two sieve mesh-size, but with the 0.5 mm sieve data a different pattern was observed during austral summer. A slight loss of information was detected using genus, family, polychaete species and their feeding guilds as taxonomic/functional units. These results together with those of the cost! benefit ratio, suggested that the family level seemed to be sufficient to detect the impact caused by moderate pollution in this shallow-water, subtropical environment. In additional, through the use of feeding guilds, similar patterns are obtained. Correlation analysis showed that chlorophyll a, total organic matter, zinc, and chromium sediment content were the variables that best explained the biological pattern observed and not always the best correlation coefficient occurring at the species level. The feeding guild approach seems to be useful and generates interpretable results similar to those obtained with the species level of the whole macroinfauna. The results showed an important cost reduction in the sample processing, suggesting that it is possible to adopt a coarser taxonomic level monitoring program even in species-rich communities.

We collected AIS information on fishing vessels operating near Jeju Island, and analyzed appearance density of the Chinese fishing vessels and inferred the movements of the fishing grounds. AIS information was received from October 16, 2016 to October 16, 2017 and stored on a hard disk through a program called AisDecoder. Unauthorized fishing vessels within the Exclusive Fisheries Agreement Zone (EFAZ) operated near the EFAZ boundary, and the frequency of appearance of fishing vessels were high in the middle waters of Korea and Japan, 252 and 250 fishing zones. Chinese fishing vessels authorized to enter appeared scattered outside the Prohibiting Fishing Zone of the Large Trawlers (PFZLT), and the closer they were to the PFZLT boundary, the higher the appearance density. And the appearance of Chinese fishing vessels with a speed from 0 to 3 knots was mostly outside the EFAZ, showing high density in the waters close to the boundary between Korea and Japan. On the other hand, within the EFAZ, the frequency of appearance of Chinese fishing vessels was also low and scattered. The appearance of Chinese fishing vessels with a speed from 3 to 5 knots mostly shows some variability within the EFAZ, but the frequency of appearance was high and the density was high. The seasonal appearance of Chinese fishing vessels in the waters south of Jeju Island appeared in the southwest in the autumn and then moved south and southeast of Jeju Island in the winter, and in the spring and summer. They were considered going to other fishing grounds without fishing in the waters south of Jeju Island.
The 21st century is called as the "Age of knowledge flood", and thus the importance of the ability which can use knowledge creatively is more emphasized. Also, not only individual problem solving but also solving problems through effective communication skills with group members are needed, and therefore, it is requested to train potential gifted learner working together with others to practice cooperation and eventually grown up as a competitive human resource to adapt successfully in future environment. In this paper, to show the effectiveness of cooperative learning in gifted learners, members for cooperative learning group has been selected using whole brain theory from the 42 gifted middle school students who participated in summer gifted learner vacation program. From the analysis of the learners' learning motivation and frequency of interactions whole brain based cooperative learning is effective for enhancing both learning motivation and interactions. Therefore, the whole brain based cooperative learning is an effective pedagogy for enhancing the motivation as well as facilitating interactions within gifted learners.
It is essential to develop legal and legislative devices like the National Environmental Act to conduct systematic and continuous environmental education. In many Countries including the Uinted States, Great Britain, Germany, and Australia, environmental education has been developing based on legal and legislative systems. Of those cases, the Uintes States made efforts to promote environmental education through legislation, which can have significant implications for us with intention to legislate the National Environmental Education Promotion Act. This study is focusing on our environmental education by studying the histiry and current situation of National Environmental Education Act, PL 91 516 of the United States and its features. In case of the United States, there has been several amendments and re-approvals. since the first National Environmental Education Act was legislated. The public hearing for the re-approval of National Environmental Education Act whIch was legislated in 1990 was held during the Summer of 2000. This gave us important reference data including the need of environmental education, its effects, and considering articles. As a result of the public hearing, 1990. National Environmental Education Act was recognized and some articles were amended. Its re-approved as John H Chafee Environmental Education Act of 2001, PL 107-S 876 IS Some implications and suggestions were drawn from the case study, which included the importance of related ministries, financial support, the role of Consulting Committee and Special Committee for environmental educators, environmental education program certification system.
This study intends to analyze open-ended inquiry activities of elementary science-gifted students in terms of how similar they are to authentic science inquiry and suggest desirable ways to make more effective programs for the gifted. For this study, we selected a small group with five elementary science-gifted students who had participated in the open inquiry program of summer camp held in the Institute for Science Gifted Education and collected data through recording and video-taping their discussion and performance from planning to coordinating inquiry results. The data was analyzed in terms of epistemological features and cognitive process in authentic science inquiry. The results is as follows. In terms of epistemology, students' inquiry methods were theory laden and they constructed knowledge in collaborative groups. For example, the students often discussed about performing the thought experiment and scientific concept related to inquiry task or their opinion. And in terms of cognitive process, their designing inquiry was similar to authentic science inquiry especially selecting variables, planning procedures, controlling variables, planning measures.
This study was designed to investigate development points for automatic ice maker which met consumer's demand. Basic data about using ices in Korean's dietary life, were collected from Seoul and Kyunggi-do residences and analyzed by SPSS program. The results were as follows; 93.7% of respondents had 3 major domestic brands' refrigerator and 41.4% of them had medium-large capacity(400-519L). 65% of respondents had a refrigerator that was purchased less than five years. 15.5% of respondents had one more refrigerator. Among of them, major refrigerator was located in kitchen(67.7%) and minor was in kitchen(29.8%) and in veranda or multi-purpose room(26.3%). 66.2% of respondents always prepared ices in ice container, and 85% of them used ice only in summer. Boiling water with barley or corn was used as drinking water (45.6%) and boiled or purified tap water was used to make ice (38.6%) commonly. In cooking, ice was used especially in cold soup with cucumber and seaweed(89.9%), ice-tea or ice-coffee(81%), and fruit punch(64%). The next commonly using ice was adding in alcoholic beverage such as whiskey(57.4%), in Koreans traditional drink(Misugaru) (45.2%) and juice. The purpose of using ice was to cool in soft drink (58.6%), to cool in cooking food(19.9%), to eat ice itself(14.0%), and to enjoy more fantastic taste and mood(3.8%). In whiskey, the purpose of using ices was to control alcoholic content (52.9%). There was no significant difference between sex in the purpose of using ice, but there was significant differences between age(p<0.05). Seasonal variations in using ice, there were significant differences according to sex, age, roles in family, amount of preparation of ice, socio-economic level and brand and capacity of refrigerator in respondent's home.
