What if the memory is not erased but continues to exist in the head as it was before? The typical answer to this question would be summarized as the "love for memory". It is almost unbearable that the memory is erased, forgotten or replaced with others. Even though three episodes may be understood as separate things, they have a different image when they are seen under one subject . he three episodes impresses the people with their unique fantastic images and artistic air. In the episode of , we can see a woman who is so much concerned with her past memory so that she does not love the present. In this episode, we can realize how much destructive the bad past memory gives effect on a woman and how memory can give bad effect on a person if that does not connect the past and the present. The work criticizes the society whichdoes not understand the current problems by depicting a person who is so preoccupied with the thing near that person only. shows that the dream is meaningless if people have the future dream without understanding what they really want. Theaudience is absorbed to each hero or heroin who is so obsessed with the past, present and future. What we can feel from these three works is the doubt about the human society which is so much preoccupied with the pessimism and the individuals who do not recognize the importance of the present because they are so much obsessed with their superficial past, present and future as well as the society where they live.

The study applied a narrative inquiry to the undergraduate interdisciplinary course taught for three years(2012~2014). Narratively I have described interactions among teachers' and students' performing the interdisciplinary consilience course with various situations such as place, curriculum and class interaction. I have specifically illuminated a three-dimensional narrative inquiry space embracing the dilemma of the consilience curriculum, PBL(Problem Based Learning) and TBL(Team Based Learning), and an effective presentation. The result of the study is as follows: First, the ratio of giving lecture is high. The burden of doing project will be reduce if the teacher decreases the lecture up to one fourth, gives students enough time to finish their tasks, and gives them advice for a better project. Second, for opening the interdisciplinary consilience class maintaining previous college curriculum, each department has to put a 'consilience course' on the existing curriculum that allows teachers open the consilience course whenever they need to teach with other department teachers. Third, an effective teaching method using the PBL(Problem Based Learning) in Team Based Learning environment is making students to consider projects as problem situations to solve and to apply the problem situations to PBL method. Lastly, teachers should give students lots of opportunities for presenting what they have learned in the class. Three times of presentation as a team member is ideal in a semester but the way of presenting has to be changed. The students in next year will relieve the tension of 30 minute instead of 15 minute, two days instead of one day for the team presentation.

Namhansan fortress of Kwangju in Kyonggi Province has remained a traumatic historical landscape of Manchu invasion in the year 1636. Skirted by the mountain fortress and on the ground of the uplifted flatland was the county seat which was relocated in 16Z7 from Kogol at the underneath ravine and later removed in 1917 to a crossroad place at the low-lying river plain. Once a secluded mountain village, Sungnaedong was at the outset planned as a county town of Kwangju, achieving thereafter a dramatic transformation from a small town of three hundred households into a nascent urban settlement of approximately six hundred households by the mid-18th century. The townscape of Sungnaedong features shrines, a second palace, a magistrate-commander's office, administrative buildings, and a periodic marketplace which were all decreed by the Neo-confucian template of the scheme of county seats. Townspeople managed to live on tilling tax-alleviated crop lands, trading merchandise, and selling their labor. Changing socio-economic situations led to the relocation of the administration center to the gateway village of Jumakri, which consequently heralded the decline of the mountain-fortress settlement of Sansungri at Namhansan.

This study was conducted to find the factors affecting somatic embryogenesis in suspension culture of Rehmania glutinosa and investigate the possibility of artificial seed production by encapsulation of somatic embryos. Linsmeier-Skoog medium was appeared as proper for somatic embryogenesis. Sucrose with $3{\sim}5%$ as carbon sources was good for somatic embryogenesis, and both ammonium and nitrate nitrogen were necesary for normal somatic embryo production. BA with NAA or kinetin with NAA were better than the use of cytokinin alone for both somatic embryogenesis and numbers of somatic embryos. $AgNO_3$ as protectant for vitrification of seedlings in vitro culture had no harmful effect on somatic embryos. Sphericity of encapsulated seeds was good at 3% gel of sodium alginate but germination was better at 2.5% sodium alginate level. Artificial seeds were germinated and developed normal shoots and roots under in vitro condition.

The local variabilities of resistance to Malathion and NAC (Sevin) were studied during 1973 with the strains of small brown planthopper (Laodelphax striatellus Fallen) collected from Jinjoo, Sunsan, Milyang, Kwangjoo and Iri districts of southern part of Korea. The susceptible lab strain used for this study has been reared successively in the laboratory without exposure to any insecticide since 1970. The insecticides were applied topically in acetone to the thoracic sternum of the adult insects. $LD_{50}$ values of Malathion to the insect were varied with the locality of the planthoppers. Relatively high levels of resistance to Malathion were observed in the strains of Jinjoo and Suntan; showing 27.7 times in female and 24.9 times in male for Jinjoo stram and 18.4 times in female and 13.8 times in male for Sunsan strain as compared with the susceptible lab strain, and in other strains of Milyang, Kwangjoo and Iri the levels of resistance to Malathion were still less than 5 times. However, there was no any specific difference among the strains in susceptibility to NAC. The malathion-resistant strain of the small brown planthopper seemed to be still localized in some regions of· Korea. The susceptibility of the planthoppers to Malathion was varied with the sex; $LD_{50}$ values based on the individual (ug/insect) were higher in female than in male, while the values based on the body weight (ug/g) conversely higher in male than in female.

IPv6 has appeared for solving the address exhaustion of IPv4 and for guaranteeing the problems of security and QoS. It occurs the unexpected new attacks of IPv6 as well as the existing attacks of IPv4 because of the increasing address space to 128bits and the address hierarchies for efficient network management and additions of the new messages between nodes and routers like neighbor discovery and auto address configuration for the various comfortable services. For the successful transition from IPv4 to IPv6, we should get the secure compatibility between IPv4 hosts or routers working based on secure and systematic policy and IPv6. Network manager should design security technologies for efficient management in IPv4/IPv6 co-existence network and IPv6 network and security management framework designation. In this paper, we inspected the characteristics of IPv4 and IPv6, study on security requirement for efficient security management of various attacks, protocol, service in IPv4/IPv6 co-existence and IPv6 network, and finally suggest integrated solution about security vulnerability of IPv6 network in considering of analysis of IPv6 system, host and application, IPv6 characteristics, modified CGA(MCGA).

In this study, the views and the meaning of nature between the Western world and East Asia were compared through literature analysis. In the West, it is recognized that nature and human beings are separate. Nature is understood as regular and rational. They, therefore, take the view of particle and mechanical theory. In East Asia, it is thought that nature and humans interact with each other, and take an attitude of compromise and tolerance. Since nature is recognized as an ever-changing being, they, therefore, take the position of wave theory. Scientific knowledge and concepts are accepted depending on the personal view of nature. In Korea, science education follows the view of modern western science without considering the personal pattern of cognition, though students can have various views of nature. The attitude is needed regarding the various viewpoints as rich resources in science and science education.

This study was conducted to reclassify Dongsong series based on the second edition of Soil Taxonomy and to discuss the formation of Dongsong series distributed on the lava plain at Cheolweon in Korea. Morphological properties of typifying pedon of Dongsong series were investigated, and physico-chemical properties were analyzed according to Soil Survey Laboratory Methods Manual. The typifying pedon of Dongsong series has brown (7.5YR 4/2) silty clay loam Ap horizon (0-16 cm), brown (7.5YR 4/2) silty clay loam BA horizon (16-22 cm), brown (7.5YR 4/2) silty clay Bt1 horizon (22-50 cm), reddish brown (5YR 5/4) silty clay Bt2 horizon (50-92 cm), and brown (7.5YR 4/3) silty clay loam Bt3 horizon (92-120 cm). It occurs on lava plain derived from baslt materials. The typifying pedon has higher bulk density than 0.90 Mg $m^{-3}$. That can not be classified as Andisol. But it has an argillic horizon from a depth of 22 to more than 120 cm, and a base saturation (sum of cations) of less than 35% at 125 cm below the upper boundary of the argillic horizon. It can be classified as Ultisol, not as Andisol or Alfisol. It has aquic conditions for some time in normal years in one or more horizons within 50 cm of the mineral soil surface, redoximorphic features between a depth of 25 cm, and a depth of 40 cm from the mineral soil surface, and redox concentrations, and 50%or more redox depletions with chroma of 2 or less in the matrix within the upper 12.5 cm of the argillic horizon. Therefore it can be classified as Aquult. It has episaturation, and keys out as Epiaquult. It has 50% or more chroma of 3 or more in one or more horizons between a depth of 25 cm from the mineral soil surface, and a depth of 75 cm. It can be classified as Aeric Aquult. Dongsong series have 35%or more clay at the particle-size control section, and have mesic soil temperature regime. Therefore they can be classified as fine, mesic family of Aeric Epiaquults, not as fine, mesic family of Typic Epiaqualfs. The Quarternary volcanic activities occurred in Jeju Island, Ulrung Island, Baekryeong Island, Cheolweon area, and Mt. Paekdu et al. in the Korean Penninsula. Most of them belong to the central eruption type, but Cheolweon area may be of the fissure eruption type. Dongsong series occur on Cheolweon lava plains derived from basaltic materials. Most soils distributed in Jeju Island, and derived from mainly pyroclastics are developed as Andisols. But Dongsong series distributed in Cheolweon lava plains which have a relatively dry climate and derived from basaltic materials are developed as Ultisols.

The results of this research to study forms, structure, changes, symbolic meanings of 16 Hahoe sceneries through analyses of "Hahwaesipyukgyeong" and "Hahwaenakgangsanghaildaedo" are as belows. The coherence of headword is not discovered in 16 Hahoe sceneries, but based on various variables and sense dependence, endemicity with original natural scenes, human's life and phenomena of riverside village are spread in 3km viewing areas within 200m from Gyeonamjeongsa(謙巖精舍) and Okyeonjeongsa(玉淵精舍). As the viewing points of Gyeonam and Okyeonjeongsa are symmetrically facing and separately independent, while viewing angles do not intersect at Wonjijeongsa (遠志精舍) and Binyeonjeongsa(賓淵精舍) because of Buyongdae(芙蓉臺), and crating each independent viewing area, we can see 16 Hahoe sceneries are perfect views by supplementing Gyeonam and Okyeon Jeongsa, as well as points of views from Wonji and Binyeonjeongsa. Meanwhile, as the view point of 16 Hahoe sceneries, Gyeomam, Okyeon, Binyeon, and Wonji Jeongsa are clearly described, and 12 natural sceneries, which are Hwasan(花山), Ipam(立巖), Maam(馬巖), Jando(棧道), Bangi(盤磯), Hoengju(橫舟), and Honggyo(虹橋), among landscape elements of 16 Hahoe sceneries that can be expressed on canvas in the Haoedo are realistically described, there is high possibility that Haoedo is the 'Mental Stroll about Nature(臥遊) of 16 Hahoe sceneries. The belted forest surrounding the village in the painting is assumed to be an erosion control forest, and considering row-expressed trees, the south belted forest may be a different broad-leaved forest from current Mansongjeong(萬松亭) pine forest. In 16 Hahoe sceneries, there is Neo-confucianism tendency, which connects the nature and human life, and moreover prioritize human life than the nature. Especially as seen in the 'Choljae(拙齋)', the pen name of 16 Hahoe sceneries' author park, the 16 Hahoe scenery poet suggests 'Beauty of Jolbak(拙撲美)' based on the simple life that upright classical scholars pursued as the basic emotion. The thinking system shown in the poet is interpreted as Neo-confucianism category including one's sense and emotion depended on natural features or phenomena. Ultimately, 16 Hahoe sceneries are landscape that reflects moral world views of Confucianism scholars who wanted to express ideal thoughts based on natural features and phenomena in reality at Jeongsa in Buyongdae and Hahoe Village.

Taiwan land race, Taichung 2 rowed barley #1 was crossed with England cultivar, Deba abed in 1972, and two isogenic lines-lax and compact heads-were made in 1982. So as to three fertilizer and three seeding density levels were treated at Dan-Kook Agricultural College farm located in Cheonan in 1984-1985. Lax head type had longer spike length and rachis than compact type. The traits uninfluenced by different head types were heading time, number of grains per spike, yield and soluble nitrogen content. However, the traits related to malting quality such as 1,000 grain weight, assortment ratio, protein content of grain and malt, malt extract, malt total nitrogen content, Kolbach index and diastatic power were significantly affected by head types. The number of spikes per m2, yield, assortment ratio, crude protein content of grain and malt yield ratio, extract yield ratio, malt total nitrogen, souble nitrogen content, Kolbach index and diastatic power were affected by fertilizer and seeding density levels in both isogenic lines. The malting quality was best at 12-12-9 kg/l0a fertilizer level and the yield was greatest at 15-12-9 kg/l0a level. Narrow-spaced or drilling seeding had greater yield and better malting quality than conventional row seeding. The plant with lax head type had some advantages in malting quality, suggesting that this trait would be considered as an selection criterion fer good malting quality lines.
