Ultraviolet resonance Raman (UVRR) spectroscopy was used to elucidate the dynamic change of the protein structure of bacteriorhodopsin (BR) during the photocycle. The photointermediates minus light- adapted (LA) BR difference spectra show Trp difference signals, which are assigned to Trp189 or Trp182 on helix F by using the mutants, W182F and W189F. The Difference signals of Trp 182 indicates an increase in hydrogen bonding strength at the indole nitrogen and a large change in the side chain conformation (X$\^$2,1/ torsion angle) in the M$_1$ \longrightarrow M$_2$ transition. On the other hand, Trp189 shows an increased hydrophobic interaction. These results suggest that the tilt of helix F occurs in the M$_1$\longrightarrow M$_2$ transition. In the M$_2$ \longrightarrow N transition, the hydrophobic interaction of Trp182 decreases drastically, The decrease in hydrophobic interaction of Trp182 in the N state suggests an invasion of water molecules that promote the proton transfer from Asp96 to the Schiff base. Structural reorganization of the protein after the tilt of helix F may be important for efficient reprotonation of the Schiff base.

This paper aims to propose a framework of content creating group with creativity under new convergence environments. The framework is built based on content concept hierarchy(deep/surface) relating with the creativity of group members. The diversity of group members(potential creativity) decrease and change into creative abilities in one unified view at each content concept hierarchy in time. To do this, three methods of building a creative group(interaction-base, direction-base, hybrid) are proposed. Cooperating processes and operators are designed to promote creative abilities in the content producing group. These cooperations are considering new media convergence industry's job road map(IPTV) and fundamental content attributes(semantic, narrative, discourse). In the framework, creative content is produced with the help of member's cultural openness, media richness and synchronicity, hierachical adaptability on dissimilarity. Deep level creativity of cognitive semiotics on moving image content is composed of psychological, transformational, situational creating abilities in the structure of group members. Designing analogy, metaphor, symbol operators help members to traverse deep structure of content concept hierarchy. Our framework has strong points to relate fundamental content deep structure with structure of content producing group and to induce creativity on cognitive structure of human being.

The purpose of this document is to provide the direction of the policy for welfare of the elderly, by identifying the problems and status of the welfare service for the elderly. The primary source of degrading the living standard of the elderly is the increase of the elderly population and life longevity. The Welfare service for the elderly to enhance the poor living level of the elderly population should be established, to compensate their former economic and social contribution in the society and also to promote the basic human right. The agenda to achieve this goal sums up like these : First, the basic living of the unhealthy elderly belonging to the low-income group, such as government-provided income and medical service should be provided. Second, for those with working ability, more opportunity for working and social activities should be given, focusing on expanding the employment rather than adding income. Third, for those with middle and high income, silver industry and pastime activities should be nurtured. Lastly, rather than institutional protection for the elderly, the welfare service for those staying home should be enforced, thus naturally leading to the family support for the elderly. There cannot be a sound policy for welfare and improvement of living standard ignoring the Well-being of the elderly population. The effort to better the welfare for the minority groups who compose the base of the social base will, eventually, result in the progress of the entire society.

In this paper, the focus was on the review of Ming General Nan Fangwei's activities during the Choson period and existing relevant historical artifacts & literacy works. Nan Fangwei's hometown was Jiangxi(江西) Changjiang(昌江; Jingdezhen景德鎭). Unfortunately, it has not been known where his descendants migrated later. During Jingdezhen Riot(景德鎭民亂), he went to serve as the head of the grass roots. After surrendering, he became a general in the Ming military base. During Jeongyujae War(丁酉再亂), he entered Chosun as a Youji general(遊擊) and participated in dozens of large and small battles. However, the defeat of Jungro-gun (中路軍) led him to a feud with the Ming's military authorities and to return him, which gave him a hard time to be forcibly dislodged to a remote region. Nan Fangwei established Namwon Guanwang Shrine(南原 關王廟). Since then, it has been preserved in Namwon Wangjeong-dong(王亭洞) through several reconstruction and reconstruction works. In addition, he took good care of people by strictly cracking down on their subordinates with high integrity and virtuous deeds at the military base. Being deeply touched by his morality and virtue, the people of Gongju(公州) established 'Youji general Nan Fangwei Jongdeokbi(〈遊擊將藍公種德碑〉)'. In addition, when he had his leisure time, he collected Korean Chinese poems from various figures and edited and published 'Chosun Poetry Collection(《朝鮮詩選全集》)', which he played a catalyst to promote high-quality Korean poems to Chinese literacy community.

The microstructural characteristics and low temperature tensile properties between $25^{\circ}C$ and $-196^{\circ}C$ for as-welded and age hardened specimen by using Al 5083-H321 for base metal, 5083-5356 and 5083-4043 weldments have been investigated. The hardness of 5083-5356 weldment decreases with aging treatment, whereas the weld region of 5083-4043 weldment shows remarkable increase in hardness after aging due to the precipitation of fine Si particle at the grain boundaries and interiors. Low temperature tensile properties of 5083 AI base metal, 5083-5356 and 5083-4043 weldments appear to be the increment of tensile strengths and elongations at the room temperature and $-196^{\circ}C$, while the decrement of tensile properties around $-50^{\circ}C$ is shown. Through the observation of fine serration to fracture in the stress-strain curve and tensile fractography, the increment of localized deformation leading to promote the neck initiation and the increment of the dimple size cause to decrease in tensile strengths and elongations around $-50^{\circ}C$. For the tensile specimen of the 5083 base metal, 5083-5356 and 5083-4043 weldments, the reason to increase in elongation after solution and aging treatment is the diminishment of fine pit, the resolution of Mg into the matrix and the spheridization of the eutectic Si.

Crystallizable glasses with precipitation of celsian were prepared for the purpose of insulating dielectric layers for the devices such as integrated circuit substrates. Crystallization behavior of these glasses were studied by DTA, SEM, XRD analysis and by the measurement of dielectric properties. The base composition of the glass-ceramic consists in weight percent of 30% SiO2, 10% Al2O3, 26% BaO, 10% CaO, 10% ZnO, 8%TiO2 and 6% B2O3. 2-6 wt% Y2O3 were selected as the nucleating agent to promote monoclinic celsian formation. As a result, in barium-rich glasses containing 4~6wt% Y2O3 , monoclinic celsian was developed as major crystalline phase in the temperature range of 850~90$0^{\circ}C$. Also, the dielectric constant and quality factor of these glass-ceramics were about 9 and more than 1000, respectively.
