The purpose of this study is to develop play education programs based on the instructional systems development (ISD). To achieve the goal, play education programs for elementary school students were developed based on the ADDIE model. Internal researchers, teaching design experts, and subject matter expert reviewed, modified, and developed play and education programs having three modules: design and scheduling, making a model, and preparing an exhibition. Students set up a program to realize the play space they want through collaboration with their peers. The program was applied to fifth grade elementary school students in Chungju for verification of the play and education program. At the end of the play education program, the FGI was conducted on 13 students to measure the overall value of the play education program, including its sustainability. Through these processes, we drew the effects and implications of the play education program and presented future research directions of play education and projects for elementary school students.

Distribution changes in microalgae communities were studied in the Nakdonggang River at two sampling stations (St.1 Gyeongcheongyo Bridge (GB) and St.2 Daedong Wharf (DW)) at monthly intervals from January 2021 to November 2021. A total of 83 taxa included 82 species, 1 forma, belonging to 49 genera, 32 families, 21 orders, and 8 classes. The most important groups were Bacillariophyta and Chlorophyta. The number of species ranged from 5 to 24 in GB, and from 9 to 21 taxa in DW. The contribution of Bacillariophyta to the total species richness was the highest during all survey periods, and Chlorophyta yielded the next highest value in the study area. The dominant taxa were Aulacoseira ambigua, A. ambigua f. japonica, and Ulnaria acus in this study. Cluster analysis and non-metric multidimensional scaling (nMDS) analysis based on Bray- Curtis similarity identified 4 major groups, which corresponded to microalgae assemblages and their characteristic species. Correlation was analyzed through the CCA analysis. It was found that there was a correlation between the microalgae and environmental factors. It was revealed that the divided groups were distinguished because of the differences by the survey period. Therefore, seasonal change was judged as a major factor affecting the distribution of microalgae communities.

The range of art has been gradually expanded with the passage of time. Science and technology have also contributed to the arts in the name of media art, and artists and technicians have become collaborative. In this paper, we investigate the meaning of collaboration in art and analyze the case focusing on Projection Mapping which is a field of Media Art. In particular, this study propose the concept and production process of Sequential Collaborative Projection Mapping works, and see the work of making and exhibition as one experiment. Based on this, sequential collaborative procedures are defined in the case of work production, and the underlying technologies and procedures for collaboration are presented. The presented techniques and procedures can be applied to projection mapping exhibitions and festivals as a platform. In this process, we have reviewed the collaborative relationship between artists and technicians, and the issues with regard to giving and receiving the credit of works.

This study was started to find a way to activate the regional tour program of the Gwacheon National Science Museum, which covers a relatively wide area among public service organizations with the theme of science. In addition to the permanent exhibition program, the Gwacheon National Science Museum has been conducting tour programs in Gyeonggi and Gangwon Province since 2018 for residents in underprivileged regions who are unable to visit the Science Museum for geographic and environmental reasons, but it lacks awareness and effectiveness compared to other areas such as culture, welfare for the elderly, and education. As a result of the study, the first was an opportunity for a very special experience. The second was the joy of the few, A total of 3 upper units and 5 lower units were derived. This has positive effects such as increasing interest in science and expanding opportunities for experience. but it can be seen that it is urgent to supplement such as systematic promotion and improvement of the quality level of contents through professional artists.

This study researched the status and prospect of the natural dye program in the Gyeongsang region, with a focus on private centers with sufficient infrastructure and abundant human resources available for natural dyes. Metropolitan cities do not own the drying house and the agricultural land for natural dyes as well as have difficulty securing the land; therefore, entire sites are limited and smaller as they are closer to the city. The one-time program of all centers has been researched to help promote and maintain centers rather than generate profit. It is shown that June-August (summer) is preferred over December-February (winter). Natural dye programs for hobby and education are operated as needed because the number of participants are low. This program uses natural indigo and Persimmon Juice for the dyeing raw materials. Programs are often outsourced by other institutes with a private certification registration system the starting of a business after obtaining certification are often found in institutes operating programs directly. Future plans do not include investments in facilities (like the enlargement of experience centers) the prospect of programs and business value is bright for business strategies that include an exhibition shop for natural dye products and program development.

The purposes of this study were 1) to identify the effects of age and sex on adolescent's psychological characteristics-egocentrism, self-consciousness, body cathexis and clothing behaviors and 2) to identify the effects of psychological characteristics on clothing behaviors in each of the 6 groups classified by sex and age. Egocentrism was measured by Kim's Imaginary Audience Scale, and body cathexis, by the modified record and Jourard"s Body Cathexis Scale. Buss's Self-Consciousness Scale was slightly modified to assess public and private self-consciousness, and five aspects of clothing behavior were assessed with the questionnaires from the previous studies. The questionnaire were administered to 713 middle and high school boys and girls, and college students living in Seoul. Data were analyzed by frequency, factor Analysis, two-way ANOVA, and multiple regression analysis. The results of this study were as follows: 1) Four factors of egocentrism were identified : Potency, Appearance/populatity, Sympathy and Justice. Four factors of clothing behavior were Clothing exhibition/dressing for others, Clothing interest, Psychological dependence, and Clothing conformity. 2) Sex and age were found to have effects on psychological variables and clothing behaviors of adolescence. Females showed higher egocentrism, self- consciousness, clothing behaviors, but lower body cathexis than males. The mean scores of egocentrism, self-consciousness, clothing behaviors tended to increase with age. However, high school boys showed unique tendency, as they showed higher scores in those variables than the other two age groups. 3) Egocentrism (Appearance/populality factor) and public self- consciousness were the most influencial variables on adolescent's clothing behavior among psychological characteristics. Private self-consciousness was found to be an important variable in explaining Psychological dependence.ence.

In April of 2003 to 2004, the gray mold disease caused by Botrytis cinerea on Hypericum ascyron was occurred in the exhibition field of Gyeongsangnam-do Agricultural Research and Extension Services, at Hamyang-gun in Korea. The disease symptoms were started with water-soaking lesions in stem and the infected plants became withered, discolored and died. The conidia and mycelia of the pathogen appeared on stems of infected plants. The conidia were 1-celled and mostly ellipsoid or ovoid in shape and their color was light gray. The size of conidia was $4{\sim}16\;{\times}\;3{\sim}8\;{\mu}m$ and that of conidiophores was $12{\sim}26\;{\mu}m$ respectively. The pathogen formed sclerotia abundantly on potato-dextrose agar. The optimum temperature for sclerotial formation was $20^{\circ}C$. Pathogenicity of the causal organism was proved according to Koch's postulate. The causal organism was identified as Botrytis cinerea based on mycological characteristics. This is the first report on gray mold of H. ascyron caused by B. cinerea in Korea.

Augmented reality makes people feel realistic and reduces the damage to cultural properties that can come into contact with the actual cultural heritage. Augmented reality has the advantage that it can show the past appearance of the historical building or relics, the environment, or related information in addition to the current real environment. Despite these values ​and advantages, As a result of researches and analyzes of the Augmented Reality contents of the National Museum, 'palace in my hand', and the Miruksa project In the field of domestic cultural heritage warriors, augmented reality technology has shown a very negative attitude such as simply showing cultural heritage content or using it as a guide. However, various conditions such as display and sensor hardware and technology needed to realize augmented reality more effectively are improving day by day. And If you have various facilities such as the idea of ​adding storytelling to the exhibits and WiFi building, In the near future, it will be equipped with a display system of cultural heritage contents that combines augmented reality with a more complete one.

In May 2002, a destructive stem rot of Obedient plant (Physostegia virginiana) occurred sporadically in an exhibition farm of Hamyang-gun, Gyeongsangnam-do Agricultural Research and Extension Services, Korea. The typical symptoms of the disease were stem rot, crown rot, wilt or blight. Upper parts of the infected stems were mostly blighted. White mycelial mats were spread over lesions and the sclerotia were formed on the stems near soil line. The sclerotia was globoid or irregular in shape, 1${\sim}$3 mm in size, and brown in color. The optimum temperature for fungal growth was about $30^{\circ}C$. The typical clamp connections were observed in the hyphae of the fungus grown on PDA, and hyphal diameter was 3.6${\sim}$9.4 ${\mu}m$. On the basis of mycological characteristics and test of pathogenecity to host plants, the fungus was identified as Sclerotium rolfsii. This is the first report on the stem rot of Physostegia virginiana caused by Sclerotium rolfsii in Korea.
