Objective: This study aimed to investigate how the eco-centered early childhood education by seasonal divisions influences the child's nature-friendly attitude and emotional intelligence. Methods: Forty 5-year-olds from 2 preschools in Gyeonggi were selected through convenience sampling and were divided into the experimental group (21) and the comparative group (19). The experimental group received eco-centered childhood education by seasonal divisions 2 or 3 times a week (33 in total). Pre-post data were collected on both groups and analyzed via t-test and ANCOVAs. Results: The key result was as follows: eco-centered childhood education by seasonal divisions influenced positively the nature-friendly attitude and emotional intelligence of children. Conclusion: Based on the result, it is recommended that eco-centered early childhood education be applied in childhood education and that relevant program be developed. Eco-centered education by seasonal divisions is meaningful in early childhood so that children can be harmonious with the nature. Furthermore, the study should be continued for the development of qualified eco-centered education.

"Regulatory Function of Lung(肺主治節)" is one of the major function of lung, but its meaning is still controversial. The word "治節(Regulatory Function)" was first discovered in "黃帝內經(Huangdineijing)". In Chinese medicine text of modern China, physiological meaning of "治節" can be roughly divided into two; one is respiratory function, and another is to help cardiovascular function of the heart. In addition to this, "治節" has been construed in various ways, but all of them is not realistic. There has been several viewpoints that '節' in '治節' means 24 seasonal divisions and they can be representatively found in "東醫寶鑑(Donguibogam)". Based on all of these views, modern western medical physiology is requirement for further study about physiology of internal organs.

Numbers structure reality and define the way people live. Both in Daoism and in Daesoon Jinrihoe they signify key concepts, notably the cardinal numbers from one through nine that classify different dimensions of the cosmos. Beyond these, the number twenty-four plays an important role. In a temporal mode, it marks the divisions or seasonal periods of the year. Consisting of fifteen days each, these periods signal (and are named after) changes in dominant weather patterns and the position of the sun. Generally activated in the body through particular seasonal activities and dietary prescriptions, in Daoism they are also the root of a series of healing exercises and certain refinement practices of internal alchemy. In Daesoon Jinrihoe, moreover, they are activated by chanting a specific incantation that invokes the twenty-four divine rulers of the divisions, originally a group of Tang Dynasty officials that in nature and function resemble the spirit generals of the early Celestial Masters. Beyond this, the number twenty-four also applies to space. Not unlike the twenty-eight lunar stations or mansions, traditional cosmology acknowledges twenty-four directions, made up of six constellations each in the four cardinal directions, complete with starry deities and divine generals. Their powers are activated with the help of written characters rather than vocal incantations, using techniques common both in Daoism and Daesoon Jinrihoe.

The purpose of this study was to analyze the differences in the understanding level of the Korean traditional seasonal customs during summer (i.e. Buddha's birthday, Dano festival, Yudu festival and Chilseok) before and after the execution of a educational program concerning seasonal customs and determine if elementary school teachers recognize a need for this kind of educational program. The subjects of this study were 168 students in the 4th grade at two elementary schools (84 students each for the experiment group and the control group) and 249 teachers at the elementary schools in Yangju city. The major results of this study are as follows : First, it was shown that there is no significant difference in the understanding level of seasonal customs between the experiment group and the control group in the pre-test, but after carrying out the educational program, it was indicated that there is a statistically significant difference between the experiment group and the control group in the post-test. Second, in addition to strongly pointing out the necessity of seasonal customs education, the teachers recognized that it is desirable to teach seasonal customs to students through the discretionary activity class corresponding to the seasonal divisions in the year and that it is especially important to perform the educational activity through traditional plays and to utilize audio-visual media. Also, teachers hoped that a seasonal customs program suitable for elementary school students would be required, along with the development of instructional materials, and finally that the schools need to further develop teacher training through field inspections and practice.

To identify daily and annual changes in outdoor airborne fungi, it is necessary to shorten the collection cycle and increase the number of measurements. In this study, measurements were performed by employing an air sampler and potato dextrose agar media on the rooftop of National Research Institute of Cultural Heritage during a period of one year (August 2018 to July 2019). The collection cycle spanned the twenty-four seasonal divisions and the collection time was 2 p.m. and 11 p.m.. Meteorological elements were collected at intervals of one hour. Furthermore, the concentration of airborne fungi was monitored and correlation analysis with meteorological elements was subsequently conducted. Obtained results indicate that the concentration of airborne fungi is found to be highest in November, autumn, night, followed by autumn, summer, winter, and spring. The concentration, type, and dominant species of airborne fungi can vary depending on factors such as rainfall, typhoons, and yellow dust (fine dust). The concentration of airborne fungi indicates a strong positive linear relationship between precipitation, number of precipitation days, and relative humidity. The concentration of airborne fungi was related to the period of increase of dead plants in terms of nutrition source, and to the high relative humidity conditions including rainfall in terms of meteorological elements.

To assess the characteristics of phytoplankton community structures related to environmental factors, seasonal surveys were conducted in the vicinity of Dokdo. In 2019, phytoplankton of four phyla and 69 species were observed. During winter, unidentified nanoflagellates dominated, with an average of 3.19×10⁴ cells L^-1. In spring, unidentified nanoflagellates occupied about 50% of the composition and a variety of dinoflagellates appeared. The summer phytoplankton population showed very low abundance. In autumn, various species of Chaetoceros appeared, along with diatoms, such as Bacteriastrum spp., Guinardia striata, and Pseudo-nitzschia spp. In addition, tropical species Amphisolenia sp. and Ornithocercus sp. were observed in both 2018 and 2019. The diversity was high in the summer of 2018 and the winter of 2019 and the characteristics of each index varied. Cluster analysis was divided into four groups according to species and population characteristics regardless of the season. The stratification of spring was particularly weak. In the autumn of 2018, the water mass was stabilized in the same way as in the summer, which is considered a suitable condition for phytoplankton growth. However, in 2019, the water masses were mixed, resulting in a low population. In a phytoplankton comparison, the dominant group showed seasonal differences, except for summer when the population was low, and the difference was most pronounced in autumn. Therefore, the waters surrounding Dokdo have different environmental and ecological characteristics from the East Sea, but the seasonal characteristics of each year are considered to be different depending on the topography, various currents, the island effect, and other factors.

This study investigated the yearly variation of pollutant loads outflowing from six watershed of Yeong-il Bay and compared the relationship of pollutant load and water quality, and estimated the Inner productivity of Yeong-Il Bay by using ${\Delta}COD$ method which analysis nonlinear process of water quality. As the estimated results for the pollutant loads of Yeong-Il Bay, total COD load outflowing from Hyeong-san river in flood season(summer) of 2001 year was 2275.0 kg/hr and in dry(low water) season(winter) 852.8 kg/hr, respectively. Load quantity in flood season was about 2.67 times than that in dry season. And as the calculated results of the net-flux of water for seven divisions, it showed that the net-flux of water increased for the divisions of the north coast and inner sea of Yeong-Il Bay but decreased for the south coast. On the contrary, for the cases which water quantity increase from land, the net-flux of water in estuary front of Hyeong-san river decreased but outflowing quantity of that though division of the south coast of Homi-got increased. Finally, this study compared the Inner productions for flood and dry season of Yeong-il Bay by using ${\Delta}COD$ method.

To investigate the characteristics of seasonal environment and phytoplankton community structure in the coastal area of Dokdo, a survey of Dokdo around waters was conducted during the four seasons. Phytoplankton of 4 phylum 72 species in four seasons were collected in Dokdo around water. The seasonal mean abundance of phytoplankton were $3.32{\times}10^4cells\;L^{-1}$ in winter, $1.04{\times}10^4cells\;L^{-1}$ in spring, $0.28{\times}10^4cells\;L^{-1}$ in summer, and $4.86{\times}10^4cells\;L^{-1}$ in autumn in Dokdo around water. During winter, the diatoms Chaetoceros spp. had dominated. During spring, when the nutrients in the euphotic layer were depleted, the nano-flagellates and Cryptomonas appeared at surface layer. In summer, the abundance of phytoplankton was relatively low, which lead to occurrence of diatoms such as genus of Chaetoceros, Rhizosolenia, and Skeletonema. In autumn, Pseudo-nitzschia spp. was the most dominant species and tropical species such as Amphisolenia sp. and Ornithocercus magnificus were observed, implying that they may have introduced within warm water current such as Kurosiwo Current. Therefore, although natural phytoplankton communities in the vicinity water of Dokdo are mainly influenced by Tsushima Warm Current branched Kurosiwo Current, their population dynamics was affected on the spatio-temporal change of physicochemical factors by short-term wind events, namely "island effect". Long-term survey research is needed to facilitate food-web response in marine ecosystem associated with phytoplankton biomass and physicochemical factors including the warm water current in oligotrophic offshore water of Dokdo, which may have significant role for sustainable use of Dokdo.

Seasonal changes of the phytoplankton community was investigated from July 2000 to April 2001 at the river bed lake, Jangjwa Lake in the Imjin River, which appeared to be the most natural condition. A total of phytoplankton were composed of 112 taxa, belonging to 5 divisions,83 species, 10 varieties,1 variety-form, 1 form and 17 unidentified species. Of those, the green algae and the diatoms were present during the investigation periods more frequently then the other taxa. The phytoplantton standing crops varied from $2,943{\times}10^3\;cells/l$ on April 2001 to $5,742{\times}10^3\;cells/l$ on January 2001. The phytoplankton standing crops had a continuous high value over $3,000{\times}10^3\;cells/l$ during the investigated periods and showed the highest value during winter period. The major dominant species were Aulacoseira granulata, Chlamydomonas nivalis v. kobayasii, Dinobryon sertularia, Mougeotia so. and Uroglenopsis americana. Among those, Chlamydomonas nivalis v. kobayasii was a major dominant species during winter period.
