The study aims at providing research trends of information freedom in Korea. A total of 97 articles, which deal with issues on freedom of information from multidisciplinary areas, were selected for this study. These articles are analyzed according to academic backgrounds, research subjects, disciplinary characteristics, and each research period. The study found that the articles, which review various aspects of freedom of information, are conducted by a number of different disciplinary fields as time passed. However, there was a certain tendency that research methods, purposes, and subjects in this area are limited and biased. As a result, it suggests that expanded multidisciplinary studies are needed and that the complex nature of issues related to freedom of information should be considered.

The incompetency and quasi-incompetency system regulated legal incompetence in the past is insufficient for protections of the adults with insufficient abilities of judgement, the criticism has been continued that the system is not efficiently respond to their rights and legal relationship formation. At last, the government introduces adult guardianship system through revising the civil law. At this point, just several months prior to the enforcement of adult guardianship system, we should be prepared to issues which may occur in the actual operation of the system. Japan has high similarities in social and culture matters with Korea and in the general operation of its adult guardianship system is similar to Korea's, Therefore, Korea should be prepared for the basis to implement the optimized system through in advance understanding the trend in Japan. The study reviews the trends of Japanese adult guardian's type, and draws suggestions for Korea by finding activity requirements and subjects focusing on the currently increasing corporation guardiancy.

Now many sustitution and false articles is used in korea instead of chenpi. To use chenpi correctly, we will make a quilitative certificational plan of chenpi to investigate all of lieraturea, records and documents. And we could reach conclusions as folloews. 1) Source In china source of Chen-pi is pericarp of citrus reticula Blanco(Family;rutaceae)and in korea source of Chen-pi is pericarp of citrus unshiu Markovich(Family;rutaceae). Though source of both countries are not same, it has no problems because of containing family plants and culture variants. 2) Harvesting and processing After the peel attained full growth, wash cleanly in water. And dry in shade or in low temporature at state of eliminating pericarp. 3) Quality (1) Functional standards Exocarp is soft and clear yellow with numerous oil sports. The less white mesocarp is the better. (2) Physicochemical standards We need to suggest new standards about hesperidin to various conditions by processing methods and storing time. The loss on drying is less than 13.5%. Ash content is less than 4.0%. A standard capacity of hesperidin is more than 4.0%. The content of heavy metal is less than 30 ppm. We can not detect reminding agricultural medicines.

To materialize the magnetoelastic devices, such as a highly functional sensor and a signal processing device, using the Fe base amorphous film which has both excellent soft magnetic and magnetostrictive properties, in this study, a new method to control the magnetic anisotropy of a highly magnetostrictive film using bias stress has been proposed and tested. The film pattern, which was stressed by its substrate bending, was subjected to annealing for relieving its stress. Successively, the compressive stress occurred by flattening the substrate was formed in the pattern. With the introduction of the residual compressive stress, the magnetization of the film pattern was aligned in the transverse direction through magnetoelasic coupling. The magnetic domain structure and magnetization curve of the film pattern of which magnetic anisotropy was controlled by the proposed method were presented to verify the availability of the method.

Aliphatic alkenals having 6 to 13 carbons were evaluated for antifungal activity against Saccharomyces cerevisiae. The activity was gradually increased with chain length, e.g., (E)-2-decenal and (E)-2-undecenal exhibited maximum potency, while (E)-2-dodecenal and (E)-2-tridecenal were completely inactive. Alkenals showed increasing inhibitory activity with chain length, as in the case of antifungal activity, towards glucose-induced medium acidification by the plasma membrane $H^+$-ATPase of S. cerevisiae. The group including (E)-2-nonenal, (E)-2-decenal, and (E)-2-undecenal exhibited maximum potency, but the potency of (E)-2-dodecenal and (E)-2-tridecenal demonstrated a sudden drop with respect to the former group. (E)-2-Nonenal revealed dose-responsive inhibition to the medium acidification and inhibited over 90% at a concentration of 1.25 mM ($175.3{\mu}g$/ml). In contrast to (E)-2-undecenal whose inhibitory efficiency increased with incubation time, inhibition by (E)-2-dodecenal was reversed with time. Of the tested alkenals, (E)-2-heptenal and (E)-2-octenal most highly inhibited ATP hydrolytic activity by the plasma membrane $H^+$ ATPase, while (E)-2-heptenal at 10 mM ($1121.8{\mu}g$/ml) showed an inhibitory efficacy of 93.2%.

To analyze the structure of phytoplankton community of the Asan Reservoir in Korea, samples were collected 6 times from March to November in 1997. A total of 204 phytoplanklon species were identified from the samples of 19 stations. Green algae dominated the phytoplankton community, accounting for 51% of species number, followed by diatoms (29%), cyanobacteria (12%), dinoflagellates (2%) ,euglenoids (3%) and other flagellates (3%). Standing stocks of phytoplankton were very high in the range of 741-613,066 cells/ml, with the highest standing stock in July. Water Booms seemed to occur in the Asan Reservoir regardless of seasons, with water bloom-causing species being Micractium pusillum, Stephanodiscus, hantzschii, Dictyospharium pulchellum, cryptomonad(> 20 ${\mu}$m), Microcystis aeruginosa, Oscillatoria tenuis, Oscillatoria sp., Aphanocapsa sp. Euglena sp., Volvox aureus. In the summer, cyanobacteria dominated algal bloom. Species diversity of phytoplankton community in the reservoir was in the range of 0.13 ${\sim}$ 3.20, and showed much difference temporally and spatially. The cluster analysis identified two different regions of upstream area and downstream area for the Asan Reservoir.

It is expected that identification and lists of $C_4$ plants in specific regions are useful not only for the ecological researches that are related to vegetation phenology and succession but also as an index of climate change. In this review, $C_4$ plants growing in South Korea were listed and their life forms were investigated. In addition, we discussed the influences that climatic change and the $C_4$ plants exerted on plant ecosystem. Photosynthetic pathway types ($C_3$ and $C_4$) for the plant species in South Korea were determined by reviewing the scientific literatures published between 1971 and 2010. Of the total 4476 species in 1123 genera and 197 families, 206 species (4.6%) in 84 genera (7.5%) and 21 families (10.7%) were identified as $C_4$ plants (including $C_3$-$C_4$ intermediate plants). Among the identified $C_4$ species, 53 species (25.7%) in 26 genera and 15 families were classified as Dicotyledoneae, while 153 species (74.3%) in 58 genera and 6 families were classified as Monocotyledoneae. The majority of the $C_4$ species belong to four families: Chenopodiaceae (15 species), Amaranthaceae (13 species), Gramineae (102 speceis) and Cyperaceae (45 species). With respect to life form composition of 206 $C_4$ species, Th-$R_5$-$D_4$-t was most dominant: 95 species (46.1%) were included in Th, 123 species (59.7%) in $R_5$, 179 species (86.9%) in $D_4$, and 122 species (59.2%) in t. The projected increase in temperature due to climate change may provide better conditions for the growth of $C_4$ plants. Such a result will have considerable impacts on the interspecific competition between $C_3$ and $C_4$ plants, the distribution of $C_4$ plants, plant phenology, and plant diversity.
