[ $PGE_1$ ] is an endogenous substance of potent vasodialator as well as inhibitor of platelet aggregation. It has been used therapeutically in peripheral arterial occlusive disease and impotence. Intracavernous injection of $PGE_1$ for erectile dysfunction has been established for several years as a treatment option for erectile dysfunction of diverse etiologies, but this mode of administration is limited by penile discomfort, pain at the injection site, inconvenience and noncompliance. As the matter of worse, the $\beta-hydroxy$ moiety of $PGE_1$ is extremely susceptible to dehydration in solution to give inactive $PGA_1$ and $PGB_1$. For the improvement of stability, rapid absorption at action site and the convenience of application, $PGE_1$ was formulated as urethral suppositories of three types of formulations, such as PEG, witepsol, and the mixture of PEG and witepsol. The stability test of $PGE_1$ and the release test in urinary suppositories were performed. Futhermore, the effect of enhancers and vehicle composition on the penetration of $PGE_1$ through excised rat skin was evaluated by permeability coefficient and enhancement ratio.

In this study, I investigated the function and the setting characteristics of 日type plan building ruins in the Hoe-amsa monastery site, that's renovated by Zen priest Na-ong(1320-76) in the later Goryeo Dynasty(918-1392), through the comparative research between China, Japan, and Goryeo in that time. The ruins of 日type plan building, located in the east side of Buddha hall ruins, is the ruins of Jungryo(衆寮). It was called as Jeondanrim, and the name can be seen from the record(天寶山檜巖寺修造記) of Yi-saek(李穡, 1328-96). It's name and the composition of plan is very similar to the Jungryo of Chinese and Japanese Zen monastery in 13th-14th century. And from it, we can see that, the priest Na-ong tried to introduce institution of Chinese Zen monastery, which he experienced during the time of study in China. But, the location of Jungryo in Hoe-amsa monastery is deferent from the Zen monastery of China and Japan, and it can be said as the setting characteristics of Hoe-amsa monastery in Goryeo Dynasty.

This study is on Yun Seon Do's site located at Bogildo, Wando-gun, Jeonnam, compares the relics found through excavation to literature records and examines the character of relics and architectural features of the site. The results of this study are summarized as follows. First, bridge and pond including Goksudang and Seojae mentioned in related literatures were found around Goksudang. In the spatial composition, the area was divided into three using the stream from the valley and pond including buildings was built at each area. Each area was connected through Honggyo, Yueuigyo, and Ilsamgyo bridges and intentionally lengthened movement was considered as the space production technique to see the valley, and upper and lower pond. Second, 11 building relics, pond and fence were confirmed around Nakseojae. The transformative process of these relics could be divided into three periods. The 1st of these period was when Yun Seon Do lived there and Mumindang, pond and waterway were arranged as straight axis. Third, Dongcheonseoksil consisted of building relics (1) for preparing for and drinking tea and pavilion (building relics(2)) and pond, and these were static with nature and used as contemplative space for viewing.

Microwave dielectric properties of $0.95 Ca_{0.85}Nd_{0.1}TiO_3-0.05LnAlO_3$ (Ln=Sm, DH, Er) were investigated as a function of sintering temperature and lanthanide ion type. A single perovskite phase with an orthorhombic structure was obtained throughout the entire range of composition. The dielectric constant (K) was dependent upon the dielectric polarizabilities and the B-site bond valence in the $ABO_3$ perovskite structure. The quality factor (Qf) of the specimens with $ErAlO_3$ was smaller than those with $SmAlO_3\;and/or\;DyAlO_3$ due to the smaller grain size. The temperature coefficient of resonant frequency (TCF) could be controlled from $107.28ppm/^{\circ}C$ at Ln=Sm to $87.23ppm/^{\circ}C$ at Ln=Er due to the changes of B-site bond valence in the $ABO_3$ perovskite structure.

The Chapel and Exhibition hall of Chul-du-san-Holy place are considered as the most important work of architect Lee Hee-Tai (1925-1980), and as a work representing Korean architecture in 1960's. What is the reason that these buildings can acquire such a remarkable estimation? This study tries to make clear this reason with an analytic method. These buildings are situated in singular site, in which small mountain comes up alongside with Han-river. Architect laid out the Chapel and Exhibition hall to the memory of 108 saints who died for their faith in this mountain, considering the specificity of the site, the direction of approach stair, and the formation of public space. Architect proposes an opposed composition of form for these two buildings. So the Exhibition hall is characterized by trabeated structure, centripetal force and Apollonian order. It has strictly proportioned facade, which is composed of two 15m-by-l5m squares and subdivided equally in three portions. The Chapel is charaterized by arcuated structure, centrifugal force, and Dionysosian sentiment. In this work, architect Lee Hee-Tai also expressed the locality of Korean architecture with the grammar of column-roof.

The purpose of this study was to provide useful information which would help web-site planning and design, product composition, and service of internet shopping malls. The sample consisted of 693 university students who had visited(Ed- in this case 'visit' means to enter an internet site; note also that the past perfect tense already conveys the meaning of 'experience') internet fashion shopping malls or purchased clothing through internet. Data were analyzed by factor analysis, frequency, t-test, and ANOVA(LSD) using SPSSWIN. The results were as follows： 1) The evaluative criteria of internet fashion shopping malls could be categorized by 4 factors： product presentation method, design, product information, sales promotion ＆ additional service; the first of which was found to be the most important. These criteria showed significant differences according to the period and time of access. Furthermore, the degree of consideration for these criteria was high, whereas the degree of satisfaction was low. 2) The evaluative criteria of clothing could be categorized by 6 factors： general characteristics of products, wearing comfort ＆ ease of management, popularity ＆ status symbolism, service, aesthetics, and textiles materials; the first of which was found to be the most important. These criteria were significantly different according to the periods, time, and purposes of access, and purchase experiences.

In this work, on-site corrosion behavior of heat resistant tubes of T91, used as components of a superheater in a power plant for up to 25,762 h, has been investigated using scanning electron microscopy(SEM), energy dispersive X-ray spectroscopy (EDS), and electron backscattered diffraction(EBSD), with the objectives of studying the composition, phase distribution, and evolution during service. A multi-layer structure of oxide scale was found on both the steamside and the fireside of the tube surface; the phase distribution was in the order of hematite/magnetite/spinel from the outer to the inner matrix on the steamside, and in the order of slag/magnetite/spinel from the outer to the inner matrix on the fireside. The magnetite layer was found to be rich in pores and cracks. The absence of a hematite layer on the fireside was considered to be due to the low oxygen partial pressure in the corrosion environment. The thicknesses of the hematite and of the slag-deposit layer were found to exhibit no significant change with the increase of the service time.
