This study compares the major nutritional components of the leaf, flesh, and seed of dry loquat (Eriobotrya japonicaLindl.). Among proximate compositions, the crude fat, crude ash, and dietary fiber of the leaf exceeded those of the seed and flesh, whereas the carbohydrate content of the leaf was lower than that of the seed and flesh. The main component of free sugars in the leaf, flesh, and seed was fructose. Total amino acids of the leaf, flesh, and seed were 552.43, 63.00, and 260.29 mg%, respectively. Although the amino acid composition of the leaf, flesh, and seed varied, glutamic acid and ${\gamma}$-aminobutyric acid were the major amino acids in the leaf, flesh, and seed. Major fatty acids of total lipid were oleic acid and stearic acid in the leaf and seed, and the major acid was linoleic acid in the flesh. Major organic acids were oxalic acid in the leaf, maleic acid in the flesh, and citric acid in the seed. Vitamin C content was higher in the seed than in the leaf and flesh.

This study was carried out to compare bone density risk factors affecting women's BMD, and to examine the relationship age, lifestyle and dietary habits for bone health by physical measurement and questionnaires. The subjects of this study were 194 women living in the Seoul area. When the subjects were divided into normal and risk groups, BMD, height, weight, BMI, total body water, soft lean mass, fat free mass, protein, mineral, body-fat of normal group were much higher than those of the risk group. The breakfast eating rate of the normal group was much higher than that of the risk group, walking time was significantly longer and exercise was more (p < 0.05). The normal group had more frequent intakes of tunas, squid, radishes, the green parts of radish, cucumbers, carrots and Iucchinis, tomatoes, and grapes than the risk group (p < 0.01 or p < 0.05). In conclusion, breakfast eating, exercise, intakes of some foods such as anchovies, radishes, carrots, zucchinis and tomatoes were significantly important factor to prevent bone density risk.

The purpose of this study is to present a design proposal of the senior housing in the city of Kimje and design guidelines for making outdoor spaces for Korean elderly. To do this, this study examined previous research papers and scholastic writings, related to elderly housing, and analyzed study cases of elderly housing. As a result, design guidelines of outdoor spaces for elderly were classified 5 types. Entrance area of housing complex is subdivided into the condition of location, the entrance of housing complex, an access road, and a direction mark. Building entrance area is subdivided into an access and waiting area, a canopy facility, and the pattern and color of boundary. In & outdoor neutral area is subdivided into a spatial standard, a patio, and a terrace. Parking lots is subdivided into a spatial standard and an entrance access. Outdoor living area is subdivided into a spatial and social standard, the usage of movable chairs, a garden, a pocket park, a lawn area, a sports area, an active and passive sports area, a promenade, a lookout area and so on. In these study cases, outdoor living area is commonly located into a community space, a nature friendly space, a health & sports space, and an outlook space and it plays positive role to the elderly. However, versatile outdoor spaces such as horticultural therapy garden is needed, which can be able to stimulate the physical senses of the elderly. This proposal is meant to create new outdoor spaces of a senior housing and to enhance the way of life of elderly.

This study explored the sandplay therapy case of a 5th grade boy who was living in a small income fatherless family from the viewpoints of both sandplay theory and related literatures. The goal of the therapy was to lessen his difficulties under the free and protected space of sandplay therapy. This study comprised 59 sessions of sandplay therapy. The subject exhibited his situations in the initial parts of therapy(1~5, the preparation for war against enemies) by putting miniatures related to Egypt and by placing Indians who were keeping the house from enemies. In the intermediate sessions(6~47, holding a ceremony), he repeated burning rituals, played finding treasures, and exhibited both struggle and construction. In the final parts(48~59, integration), he showed integration by expressing the adaptation to the collective. This study indicated the effectiveness of sandplay therapy, because his maladjustments in both school and home were reduced.

The study examined and compared relationships among self-esteem, self-efficacy, and academic achievement of children in poverty and the comparative groups. The subjects of this study were 97 elementary school students who had benefited from the free meal project and 97 students as the comparative group who did not receive the benefit. Descriptive statistics, Cronbach's ${\alpha}$ tests, and multiple regression analysis were employed to analyze the data. The results showed that academic scores of the comparative group were statistically higher than those of children in the poverty group in Korean language, mathematics, science, and sociology. Also, self-esteem of children in the poverty group was lower than that of the comparative group's in terms of leadership and popularity. The poverty group also showed lower self-efficacy in self-regulated efficacy tasks. Finally, multiple regression analysis demonstrated that different sub-factors of self-esteem and self-efficacy predicted the academic achievement of children in poverty group and the comparative groups.

We performed a study to understand the dietary situation in North Korea and to compare the difference between the North and the South. Two hundred North Korean defectors from the North since 1990 participated in this survey. Information was collected from December, 1997 to February, 1998 by mailing pre-tested questionnaires, which had been confirmed by 10 previous interviewers. The final data from 157 defectors(107 male and 33 female with 17 unidentified gender) were analyzed. We found that (1) North Koreans are lower in height, weight and BMI than South Koreans, (2) The North Korean diet is very simple and monotonous. It is limited to their local and unprocessed foods and dishes, which is far from the trend of globalization and readiness. (3) On the other hand, in the North, the government control on foods diminished because food shortage leads to free market activity where housewives manage their own foodservices, and to accelate their eating-out behaviors. (4) Profound differences between the South and the North in dietary life are noticed by the defectors as English words and Korean words. Efforts to understand and learn about each other is necessary before not too late.

Some marine microalgae and cyanobacteria form mutualistic symbioses with diverse invertebrates, particularly cnidarians. Among microalgae, dinoflagellates in the family Symbiodiniaceae are the most well-known symbiotic partners of jellyfish and corals. However, the symbioses involving other dinoflagellate families, nano- and micro-flagellates, diatoms, and cyanobacteria with cnidarians are not well understood. As an initial step, it is essential to explore the survival of these microorganisms inside cnidarians. We monitored the survival of eight microalgal species (nine strains) and one cyanobacterium species every day for seven days after injecting each into the medusa of the moon jellyfish Aurelia aurita. The dinoflagellates Effrenium voratum (free-living [FL] and living-in-coral strains), Cladocopium infistulum, Prorocentrum cordatum, Prorocentrum koreanum, Symbiodinium microadriaticum, the prasinophyte Tetraselmis suecica, the chlorophyte Dunaliella salina, and the raphidophyte Heterosigma akashiwo survived inside the medusa, while the cyanobacterium Synechococcus sp. was not detected. Additionally, E. voratum (FL) survived within the medusa for 60 days and gradually spread to adjacent areas, indicating potential for artificially established symbiosis. The results of this study provide a basis for artificial symbiosis between microalgae and invertebrates.

The purpose of this study was to explore the possibility of creating barrier-free exhibition-appreciation environment based on the visually impaired person's perspectives. Participants were selected by the purposeful sampling method. Researchers conducted a couple of in-depth interviews with four visually impaired persons. Yin's case study method was employed to analyze qualitative information. The analysis revealed nine sub-themes in two sections: three from 'accessibility within the exhibition room'; and six from 'demand for immersive exhibition environment.' Based on the results, following suggestions were presented: First, we need to provide quality information appropriate for artworks-appreciation; secondly, to ensure the visually impaired people to appreciate the culture and arts without any barrier, we need to extend certification of barrier-free living environment to exhibition-appreciation area. Finally, to facilitate these two tasks we need to encourage the convergence research among science and technology, humanities and society, and culture and arts.

The free learning semester system focuses on the activation of career education of middle school students as an educational policy that links career recognition in elementary school, career search in middle school, and career planning in high school. This system was fully implemented in 2016 and public libraries also provided various programs. This study analyzed the free learning semester system programs of public libraries in Busan city and demonstrated the contribution of local development. As a result, career and job search, career exploration and experience, and information literacy enhancement programs contributed to local knowledge culture, reading culture, learning culture, living culture and leisure culture. However, contribution of reading exhibitions, job experience, information literacy enhancement to the leisure culture and local economy were limited. Therefore, it is desirable that all libraries should add programs related to knowledge ecosystem structure, digital information gap, human healing, social environment issues, future job prospects, and provide information literacy programs.
