This study is to describe the meaning of associations at $5{\cdot}18$-related photographic portrait phenomenologically. Referent in the photography arouses different and unique type of associations. Moreover, it appears differently emotional experience by the associations. Therefore, the purpose of this study is to describe types of associations and emotional experience about referents gained through $5{\cdot}18$ photography and to construct the meaning. It is based on concepts of primordial associations discussing in the phenomenology but this study was described the meaning of $5{\cdot}18$ the May 18th democratic uprising focusing on types of associations and meanings derived by direct experience from photography. According to this result, the viewpoint of $5{\cdot}18$ Democracy Movement approaches from objective academic system or cannot be withdrew as dynamics of the political ideology. It is that the fundamental and impulsive emotions from each individual who participated in the movement are affected. The fundament of the May 18th democratic uprising is based on their basis of life and the will to primitive power of a love & affective community.

Levels of total lipids in the seeds of three species of the Pinaceae family were determined and their fatty acid compositions were also analyzed by a gas-chromatograph equipped with a capillary column coated with Carbowax 20M. The results are summarized as follows: Lipid contents of the seeds amounted to 56.9% in P. koraiensis, 29.9% in P. thunbergii, and 21.2% in P. rigida. In all lipids 19${\sim}$20 fatty acid were detected and, surprisingly, fatty acids having ${\Delta}^5$-non-methylene interrupted conjugate double bond such as ${\Delta}^{5, 9}-C_{18:2},{\Delta}^{5, 9, 12}-C_{18:3}\;and\;{\Delta}^{5, 11, 14}-C_{20:3}$ occurred in appreciable amounts. In the lipids of P. koraiensis, the main component was $C_{18:2}{\omega}_6(45.0%)$, followed by $C_18:1{\omega} _9(26.9%)$ and ${\Delta}^{5, 9, 12}-C_{18:3}(14.6%)$, and then ${\Delta}^{5, 9}-C_{18:2}(2.2%)$ and ${\Delta}^{5, 11, 14}-C_{20:3}$ were also present. Levels of saturated fatty acid such as $C_{16:0}\;and\;C_{18:0}$ were as low as 7.5%. The seed oil of P. thunbergii predominantly comprised $C_{18:2}{\omega}_6(45.2%)$, and was then occupied by equal amounts ${\Delta}^{5, 9, 12}-C_{18:3}(18.1%)$ and $C_{18:1}{\omega}_9(18.1%)$. Its ${\Delta}^5, 11, 14}-C_{20:3}(5.8%)$ level was the highest in the samples tested. ${\Delta}^{5, 9}-C_{18:2}(2.8%)$ was also detected with other minor components. In the oils from the seeds of P. rigida, $C_{18:2}{\omega}_6$ was present as a main component, accompanied by $C_{18:1}{\omega}_9(21.6%)$ and ${\Delta}^{5, 9, 12}-C_{18:3}(20.3%)$. The latter showed higher level than in any other samples. A minor component corresponding to ${\Delta}^{5, 9, 12, 15}-C_{18:4}$(not confirmed by GC-Mass) occurred in P. thunbergii and P. rigida.

In order to gain fundamental information on the utilization of lipids as energy source in mud-skipper, muscle lipids and their fatty acid composition were investigated with respect to life cycle-maturation (Aug), before-hibernation (Nov), and after-hibernation (Apr). Crude and neutral lipid were found to decrease from 1.2, 68.3% (Aug) via 0.7, 53.8% (Nov) to 0.4, 42.6% (Apr), respectively, whilst phospholipids and glycolipids increased from 29.5 and 2.2% (Aug) to 52.1 and 5.3% (Apr), respectively. In neutral lipids, TG contents gradually decreased from 53.8% (Aug) via 33.6% (Nov) to 23.1% (Apr), while FFA and sterol contents increased from 13.5 and 14.2% (Aug) to 22.3 and 24.5% (Apr), respectively. In phospholipids, PC content decreased from 61.2% (Aug) to 50.6% (Apr), while changes in PS and PE contents, as a whole, showed the opposite trends. In neutral lipids, the levels of some fatty acids such as 16:0, 16:1, 18:0, 18:1 and 20:5 $({\omega}3)$ were analyzed to be high, with the 20 : 5 being predominant, and the levels of saturated and monoene-acids gradually decreased, while polyene-acids increased in before and after hibernation. In before hibernation, 16:0, 16:1, 18:1 mainly decreased but 18:2, 18:3 $({\omega}3)$ and most of saturated and monoene acids such as 14:0, 14:1, 16:1, 18:0, 18:1 slightly decreased in after hibernation. From these findings, it was suggested that those fatty acids decreased during hibernation were used as a energy source, particularly 16:1 and 18:1 being most preferentially used. In phospholipids, the levels of 16:0, 18:0, 20:5 $({\omega}3)$, 22:5 $({\omega}3)$ and 22:6 $({\omega}3)$ were found to be high. Throughout the life cycle, the levels of monoene-acids in phospholipids stayed constant, whilst those of 18:2, 18:3 $({\omega}3)$ and saturated acids such as 16:0, 18:0 were found to be decreased gradually in before and after hibernation, whereas those for the high degree of polyene-acids such as 20:4 $({\omega}6)$, 20:5 $({\omega}3)$, 22:5 $({\omega}3)$, 22:6 $({\omega}3)$ increased, particularly 20:4 $({\omega}6)$, 20:5 $({\omega}3)$ being most increased.

The triglyceride compositions of peach kernel and apricot kernel oil have been investigated by a combination of high performance liquid chromatography (HPLC) and gas liquid chromatography(GLC). The triglycerides of peach kernel and apricot kernel oil were first separated by thin layer chromatography(TLC), and fractionated on the basis of their partition number(PN) by HPLC on a C-18 ${\mu}-Bondapak$ column with methanol-chloroform solvent mixture. Each of these fractionated groups was purely collected and analyzed by GLC according to acyl carbon number(CN) of triglyceride. Also the fatty acid compositions of these triglycerides were determined by GLC. From the consecutive analyses of these three chromatography techniques, the possible triglyceride compositions of peach kernel and apricot kernel oil were combinated into fifteen and thirteen kinds of triglycerides, respectively. The major triglycerides of peach ternel oil were those of $(3{\times}C_{18:1}\;30.9%)$, $(2{\times}C_{18:1},\;C_{18:2},\;21.2%)$, $(C_{18:1},\;2{\times}C_{18:2}\;10.6%)$, $(3{\times}C_{18:2}\;3.8%)$, $(C_{18:0},\;2{\times}C_{18:1},\;1.8%)$, $(C_{16:0},\;C_{18:1},\;C_{18:2},\;1.5%)$, $(C_{18:0},\;C_{18:1},\;C_{18:2},\;1.1%)$ and those of apricot kernel oil were $(3{\times}C_{18:1},\;39.5%)$, $(2{\times}C_{18:1},\;C_{18:2},\;24.5%)$, $(C_{18:0},\;2{\times}C_{18:2},\;14.2%)$, $(3{\times}C_{18:2},\;2.0%)$.

This study presents a plan for a memorial park that respects the characteristics based on the historical facts for the concept of space of the Gwangju Hospital of Korea Army and the location of the 505 Security Forces, which were designated as historic sites after the 5-18 Democratization Movement. The Gwangju Metropolitan City as it is the location of the 5-18 historic sites, is taking part in the 5-18 Memorial Project, and plans to establish a city park recognizing the historic site of the 5-18 Democratization Movement, which has been preserved only as a memory space to this point. The park is promoting a phased development plan. This study suggests that the 5-18 historic sites can be modernized and that social consensus can establish the framework of the step-by-step planning and composition process to ensure the plans for the space heals wounds while preserving the history. In this paper, we propose a solution to a problem. We solve the approach for space utilization through an analysis of precedent research and planning cases related to park planning at historical sites. In addition to exploring the value of the site, we also describe the space utilization strategy that covers the historical characteristics and facts while maintaining the concept of park planning. As a result of the research, the historic site of the Gwangju Hospital of Korea Army is planned as a park of historical memory and healing in order to solve the problems left behind by the 5-18 Democratization Movement. The historic site of the 505 Security Forces was selected as an area for historical experiences and a place for learning that can be sympathized with by future generations of children and adolescents in terms of expanding and sustaining the memory of the 5-18 Democratization Movement. In the planning stage, the historical sites suggested the direction of space utilization for representation as did the social consensus of citizens, related groups, and specialists. Through this study, we will contribute to construction of a memorial park containing historical values in from 5-18 historic sites. It is meaningful to suggest a direction that can revitalize the life of the city as well as its citizen and can share with the history with future generations beyond being a place to heal wounds and keep alive the memory of the past.

The interactions of 11 kinds of primary and secondary alkylammonium ions with cyclic (12C4, 15C5, 18C6, DT18C6 and DA18C6) and acyclic$(Q_2O_5)$ polyethers were investigated by NMR titration and conductometry. All of the alkylammonium ions under investigation form the relatively stable 1 : 1 complexes with crown ethers and acyclic polyether by H-bond. The interactions of alkylammonium ions with analogeous hosts having different size were in the order of 18C6 > 15C5 > 12C4, and the strengthes of donor atoms toward the alkylammonium ions were in the order of N > O > S. 18C6 forms more favorable interactions with primary alkylammonium ions than secondary alkylammonium ions, otherwise DA18C6 shows the opposite behaviors. The stability constants for complexations of 18C6 with the alkylammonium ions were determined conductometrically in methanol at 25$^{\circ}C$. The major factors affecting the stability of complexes were the type of alkylammonium ions, the length of alkyl-chain and the steric hindrance due to the structure of alkyl groups on complexation.

The May 18 Democratic Movement has been considered to be specific case of the big deviation in social memory among the events that occurred after the Korea War. Compared with other events associated with the democratization movement, the May 18 Democratic Movement is special in that can be achieved various changed meaning. In this study, primary focus will be on the background and logics to show what changed the meaning of the May 18 Democratic Movement from the perspectives of the memorial project. And to investigate influences of change of meaning on perspectives and forms of memorial projects. Recognition and forms of memorial projects on the May 18 Democratic Movement had been largely changed around 2000s. Memorial projects were the aspects that are the logics of the social movements absorbed into the logics of the institutionalization before 2000s. During this period, it was done primarily the discourse of a holy ground for democracy and sanctuarization, had characterized the nature of the struggle of memory. After 2000s, the May 18 Democratic Movement has been interpreted historical resources to create a cultural city and a human rights city. Sometimes the May 18 Democratic Movement was appropriated by local development discourse, and sometimes was adopted as the material of differentiation strategy in the city. Form of memorial projects has also been changed type of struggle of memory to type of heritage industry.

In May 2011, the 1980 Archives for the May 18th Democratic Uprising or the "5 18 Gwangju Democratization Movement" were registered as a UNESCO Memory of the World. This historic moment told the world that the 5 18 movement is a valuable and historical asset. However, despite the international recognition, archives that deny of such facts are still rampant because of misdirected standings and prejudices. These sources even develop discourses by distorting the archives to justify their claims. Accordingly, the study aimed to identify how these sources form ideologies surrounding the 5 18 movement discourses, which are characteristic of extreme social standings. It explored the possibility of the distortion of archives presented for each discourse and reconsidered the archivists' positions and roles to cope with such possibility. In addition, the author aims to suggest a more systemic strategy to advance the existing responses against the distortions, as well as provide discourses that are based on true and accurate archives mainly to students who have not yet been introduced to such distorted discourses. In the future, archivists shall try to develop positive awareness about the 5 18 discourses rather than maintain passive positions that provide information from limited archives. Through this, it is expected that this study will advance future analyses that would be effective against the distortion of archives.
