This study aimed to identify the impact of make-up education program on the level of satisfaction with make-up and the self-esteem of 80 elderly women. This education was provided during 8 weeks from May 28 to 16 July 2010 to women over 60 who were visiting P seniors welfare center, in D city. Some people fell out of the research, so finally the experimental group was 34 and the control group 36. During this research seven methods of make-up, including that of light make up were taught to the experimental group. Comparing the satisfaction and self-esteem levels before and after education. The result was that through the education the levels of their satisfaction with make-up and of their self-esteem were shown to have increased (p<0.05), significantly. We hope that through this research old people's healthy living and their social confidence can better converge.

As the media environment surrounding us has changed rapidly, the influences of traditional media decrease whereas promotions using new media have been developing remarkably, Under this circumstance, cross-media advertising, which strategically integrates advertisements on multiple media, is getting attention as an effective marketing communication approach. This study investigated consumer responses to cross-media advertising using both online and offline media, focusing on the effects of product involvement, attributes of media connection, and gender. The experiment was conducted towards adult consumers aged 20 to 39. Results confirmed that the interaction effect between product involvement and attributes of media connection on brand attitude and behavioral intention was significant by a moderating role of gender. Based on the results from this study, both theoretical and practical implications were discussed, as were directions for future research.

In this paper, we studied structural and magnetic properties of Ba-ferrite thin film deposited on Si(100) substrate with various underlayers. Ba-ferrite thin films with various underlayers were deposited by reactive RF/DC magnetron sputtering system at room temperature. various underlayers was reactive sputtered with O$_2$. After deposition, the thin films were annealed at 850 $^{\circ}C$ to get the crystallized sample. Underlayers were used to prevent interdiffusion from Ba-ferrite thin film to substrate. The growth of Ba-ferrite thin films was influenced by underlayers. Easy magnetization direction is in-plane. From these results the Ba-ferrite film with various underlayers can be used as longitudinal recording media.

In this study, the concentrations of As, Cd, Cu, Pb and Zn in agricultural soils across a region of South Korea (Buyeo County) were investigated. Their pollution sources were assessed using multivariate statistical analysis, and Geographic Information System (GIS) technology was used to determine the distribution of these elements. Surface soil samples were collected from 114 locations across the agricultural fields in the study site. Cu and Zn were derived from natural sources (i.e., parent rocks of the soil), whereas As, Cd, and Pb were found to be originated from abandoned mines. The results of this study clearly show that the transport of anthropogenic As, Cd, and Pb is governed mostly by the specific environment of the paddy soil. Our approach was effective in clearly identifying the sources of metals and analyzing their contamination characteristics. We believe this study will provide useful information to future studies on soil pollution by anthropogenic sources.

Since flash memory cannot be overwritten, new data are updated in new area. If data are frequently updated, garbage collection which is achieved by erasing blocks, should be performed to reclaim new area. Hence, because the count of erase operations is limited due to characteristics of flash memory, every block should be evenly written and erased. However, if data with access locality are processed by cost benefit algorithm with separation of hot block ad cold block though the performance of processing is hight wear-leveling is not even. In this paper, we propose CB-MB (Cost Benefit between Multi Bank) algorithm in which hot data are allocated in one bank and cold data in another bank, and in which role of hot bank and cold bank is exchanged every period. CB-MB shows that its performance is 30% better than cost benefit algorithm with separation of cold block and hot block its wear-leveling is about a third of that in standard deviation.

Two naturalized species, Euphorbia dentata Michx. and Securigera varia (L.) Lassen were newly reported from Korea. Euphorbia dentata, "Top-Ni-Dae-Geuk", was found from Jungbu Highway, Daechang-ri, Daechang-myeon, Yeongcheon-si, Gyeongsangbuk-do. It is distinguished from E. pulcherrima by its life form, which is herbaceous, and its upper leaves, which are uniformly green. Securigera varia, "Wang-Gwan-Gal-Kwi-Na-Mul", was found from Hangang, Yeouido, Seoul. The genus Securigera is unrecorded in Korea and distinguished from genus Hedysarum by rose-colored flowers, a peduncle 5-10 cm and by having dense umbels at the tips of the peduncles.

The purpose of this study is to provide basic data for habitat restoration by implementing a series of processes of capturing and translocating Kaloula borealis and managing them in artificial breeding facilities. The study site in Samcheon, Jeonju-si, Jeollabuk-do was a waste landfill site in the past, and Kaloula borealis was found during the Samcheon Ecological River Restoration Project around March 2018. To restore the habitat, a plan was established to capture, translocate, artificially breed, and release Kaloula borealis at the site. The capture methods of adult Kaloula borealis were pitfall trap and drift fence, direct capture, and deep barrels. During 2018-2019, 86 adults of Kaloula borealis were captured and translocated to artificial breeding facilities. VIE-tagging was inserted under the skin for monitoring. For artificial breeding, Gryllus bimaculatus with oyster powder and vegetables were regularly supplied to feed Kaloula borealis. At the end of October 2020, 150 young Kaloula borealis raised in artificial breeding facilities were found not entering hibernation, so they were managed in a separate artificial breeding facility. Some young and adult Kaloula borealis currently hibernating will be scheduled to be continuously managed in artificial breeding facilities and released to the restored habitat in the spring of 2021.

Yeongbojeong was a famous pavilion of Joseon, which was located in Chungcheong-Suyeong, Ocheon-myeon, Boryeong-si. It was an open place for poets and calligraphers to freely visit during 400 years. Until today, it is widely said that Yeongbojeong was newly built by LeeRyang in 1504, who was Sugunjeoldosa(naval forces officer). The researcher investigated Gyujanggak to search Lee Maenghyu's "Asulrok-Book", and it was determined that Yeongbojeong was created by Gang Soon, 36 years earlier than LeeRyang. Accordingly, this research aimed at determining the appropriateness of the creation of Yeongbojeong. "Asulrok-Book", which said, "Yeongbojeong was Wonjeong(園亭) of Gang Soon during Yejong's reign", however this research could settle imperfection of Geungeo Gimun which was not clearly explained. Yeongbojeong was created due to Gang Soon's Wonjeong in 1468, however he was also a traitor and was executed, so that nobody wanted to mention about it. Therefore, it was determined that no phrase related to the record of creation of Yeongbojeong by Gang Soon out of lots of Yongbojeong Jeyoungsi and Gimun. Lee Maenghyu was a brave scholar who recorded 'Yeongbojeong was Gang Soon's Wonjeong' confidently, breaking such taboo. This research intended to clearly investigate the year of foundation of Yeongbojeong and establish the history of Chungcheong-Suyeong by thoroughly analyzing newly discovered "Asulrok-Book", existing "Ocheong GoonJi", and "Chungcheongsaryejib" and considering the fact relevance. As the result of this research, it was determined that Yeongbojeong was Gang Soon's Wonjeong through "Asulrok-Book". The point that Yeongbojeong was forfeited reverted to neighboring Chungcheong-Suyeong after Gang Soon was executed due to his participation in a conspiracy also was a newly discovered fact. LeeRyang, Sugunjeoldosa, can be said a brave commander, since he put up the original Yeongbojeong instead of abandoning the name Yeongbojeong of Gang soon. So far, Yeongbojeong is widely accepted as 'new construction of Yeongbojeong by LeeRyang in 1504'. However, since the record of Gang Soon's Wonjeong was discovered, and as the result of diversified analysis and examination, it is proper to correct the foundation year of Yeongbojeong as 1468.

In this study, the reproductive behavior and embryonic and larval development of the short ninespine stickleback Pungitius kaibarae was described and illustrated based on observations during spawning, hatching, and larval rearing trials. Adult P. kaibarae were collected downstream in Jinhae during the reproductive season (April-May). Males had nuptial coloration on their entire black bodies, with blue dorsal spines and yellow eyes, whereas females had a brown spotted pattern on their bodies. Males built nests on the stems of water weeds and attracted females. Fertilization occurred in the nest immediately after spawning, and males guarded the eggs until hatching. The fertilized eggs of P. kaibarae were spherical, demersal, adhesive, and transparent, and each egg measured 1.43 ± 0.07 mm in diameter. The morula, blastula, and gastrula stages, as well as hatching began at 5, 18.5, 21.5, and 96 post fertilization (HPF), respectively, at 20.0 ± 0.5℃. The newly hatched larvae had a total length (TL) of 5.67 ± 0.50 mm, with a yolk volume of 0.583 ± 0.059 mm³. Their mouths and anuses had not yet opened. At 2 days posthatching (days post hatching, DPH), the yolk was completely absorbed and the larvae began to feed exogenously. Pigmentation was observed in freshly hatched larvae 4 h after hatching, with the presence of eight areas with a dotted pattern on the dorsal surface of the larvae and dispersed spots on the head and yolk sac. At 30 DPH, the TL of the juveniles was 21.34 ± 1.70 mm. The nest area and number of eggs were 259.56 ± 101.39 mm² (75.18-506.04) and 155.33 ± 114.12 (0-437), respectively.

Delegation is a powerful mechanism that allocates access rights to users to provide flexible and dynamic access control decisions. It is also particularly useful in a distributed environment. Among the representative delegation models, the RBDM0 and RDM2000 models are role delegation as the user to user delegation. However, In RBAC, the concept of inheritance of the role class is not well harmonized with the management rules of the actual corporate organization. In this paper, we propose an Adding Attributes on Permission-Based Delegation Model (ABDM) that guarantees the permanence of delegated permissions. It does not violate the separation of duty and security principle of least privilege. ABDM based on RBAC model, supports both the role to role and user to user delegation with an attribute. whenever the delegator wants the permission can be withdrawn, and A delegator can give permission to a delegatee.
