This study was carried out to investigate the characterization of cadmium adsorption by cellulose hydrogel and aerogel. Hydrogel and aerogel were made from ashless pulp dissolved in alkali hydroxide-urea aqueous solution and manufactured in film and bead types. After regeneration of cellulose, hydrogel went through the process of substitution of organic solvent and freeze-dry in order to make aerogel. SEM was used to analyze the microstructure of hydrogel and aerogel. Experiment was conducted in various concentrations and pH conditions to find out the characteristic of cadmium adsorption. After that, EDS was used to identify existence and distribution of cadmium in hydrogel and aerogel. The result from comparisons of cadmium adsorption shows that bead type aerogel has the maximum cadmium adsorption and film type hydrogel has the minimum cadmium adsorption.

This study tries to understand the characteristics of a man's clothes from the late 17th century to the early 18th century, held by the Ewha Womans University Museum. The author adopted the Assy CAD, an apparel CAD system developed by Assysit Company of Germany, in measuring clothes which is intended to solve the problems raised in the previous measurement of clothes, as well as in the making of patterns. The author used tracing paper to make copies of the curved parts, put them into the computer by digitiger, and made the patterns for more accurate restoration. Furthermore, the author compared Lee Hwang's with the contents of the related literature and excavated apparel from other tombs. As a result, Chopri among Lee Hwang's clothes, retained the typical characteristics of the mid-Chosun men's fashion in its ratio of bodice to skirt, form of sleeves, and size of breast- ties for fastening which appeared in the 17th century. Daechangeui and Jungchimak also were distinctive for Changot and the width of sleeves since the 17th century and were in wide use not only as the daily clothes but also as the shroud. These changes were brought about from the two wars which emphasized prestige and beauty of the clothes rather than their functions. As a result, Changeuis were used more widely, while Chopri which was used as the underwear of officials' uniform, was in decline.

Silicon nanowire devices fabricated by bottom-up methods are attracted due to their electrical, mechanical, and optical properties. Especially, to functionalize the surface of silicon nanowires by molecules has received interests. The changes in the characteristics of the molecules is delivered directly to the surface of the silicon nanowires so that the silicon nanowire can be utilized as an efficient read-out device by using the electronic state change of molecules. The surface treatment of the silicon nanowire with light-sensitive molecules can change its optical characteristics greatly. In this paper, we present the optical response of a SiNW field-effect-transistor (FET) conjugated with porphyrin molecules. We fabricated a SiNW FET and performed porphyrin conjugation on its surface. The characteristic and the optical response of the device shows a large difference after conjugation while there is not much change of the surface in the SEM observation. It attributed to the existence of few layer porphyrin molecules on the SiNW surface and efficient variation of the surface potential of the SiNW due to light irradiation.

The main purpose of this study was to explore the possibility of the mimetic reconstruction of artistic space through works of Hwang, Jai Hyoun. His work shows a new world that is not reduced to his life and experiences. But his work has drawn the world with an unpredictable way. This world I call artistic space, and try to interpret the processes that space is created by mimesis. To this end, I first suggest a way to communicate with his work at the intersection of light and darkness(2). I also look at the inside and outside of his art space restructured with mimetic reactions(3). Then I finally critically discuss the artistic space that has time(4), and then get out of the way(5).

This article as an attempt to analyze Jin-beop-joo(眞法呪, incantation of true law) and the view of Yang-wui Sangje(兩位上帝, Sangje in two Godship) corresponds to the second preliminary work prior to the research on the view of Sangje in Daesoonjinrihoe. The points of this article are as follows: First, Jin-beop-joo and 15 Godship(神位) based hereupon are one of the most essential elements comprising the view of Sangje in Daesoonjinrihoe. Since the other Jeungsan line religious orders except Daesoonjinrihoe does not use 15 Godship in explaining and understanding Jeungsan, this fact should be regarded as an important characteristic of Daesoonjinrihoe. Second, 15 Godship is the important installation to assemble Sangje and the other gods in the same place. In Buddhism temples and China-Taoism temples, the gods each are placed in a separate palace. Whereas Sangje and the gods are concentrated in the same place, Yound-Dae(靈臺) which is the shrine of Daesoonjinrihoe. This fact shows Sangje takes the reins to the gods visually. 15 Godship facilitates that system. Third, the number 15 of 15 Godship symbolizes the natural laws of the cosmos. Thus the shrine of Daesoonjinrihoe implies the law of universe emblematically. Forth, 15 Godship shows that the Highest God in Daesoonjinrihoe are located in the middle of the functional gods ruling over nature like mountain, sea, season, the Great Dipper, and Taoistic or Buddhistic gods like Ok-hwang Sangje(玉皇上帝, The Great Jade Emperor), Seoga-Yeorae(釋迦如來, Tathāgata Buddha), Kwan-seong-Jegoon(關聖帝君, Holy god Guan Yu), along with various envoys and ancestral gods. Besides, considering the fact that the majority of 15 Godship consists of the Eastern deities, it verifies the view of Sangje in Daesoonjinrihoe is built in the Eastern religions. Fifth, whereas the other Jeungsan line religious orders have a tendency of understanding Jeungsan as Ok-hwang Sangje, Daesoonjinrihoe worships Jeungsan as Gu-cheon Sangje(九天上帝), not as Ok-hwang Sangje. This accords with the following fact; Jeungsan is the highest ruling entity in Gu-cheon, whereas in Jinbeonju, which was handed down from Jeungsan, the highest ruling entitiy in Gu-cheon is expressed as a different being from Ok-hwang Sangje. Sixth, Daesoonjinrihoe understands Sangje as the form of two Godship, Yang-wui Sangje, which are Gu-cheon Sangje and Ok-hwang Sangje. Judging from the form of salutation, the status of these two Sangjes are the same. Yet, the object of belief is Gu-cheon Sangje as the highest God, while Ok-hwang Sangje is stipulated as the one who has wielded a true law succeeding to the Gu-cheon Sangje's will. The religious term of Yang-wui Sangje don't imply meaning Gu-cheon Sangje and Ok-hwang Sangje are the same rank. Yang-wui Sangje is the term expresses Sangje in two Godship and involves the orthodox heritage of Daesoonjinrihoe. Along with An Introduction to the Study of the Outlook on the Highest Ruling Entity in Daesoonjinrihoe (I), this article is written, while giving a thought to construct the religiography on the highest God in Daesoonjinrihoe. I hope this article accompanied with the previous one, can be contributed to the fertilization of the soil in the field of Daesoon religious studies.

This study is to establish the items on instructional evaluation based on the teacher's practical knowledge in mathematics educations. Namely, this study deals with the items on how pre-service or in-service teachers reflect and revise their own or peer's class. To accomplish this, first of all the items on instructional evaluation was developed by researchers of this study on the basis of the results of two previous study. One is the literature of Elbaz(1981) and the other is the literature of Hwang(2013). Elbaz(1981) defined the definition of practical knowledge and five sub-domains of the practical knowledge. On the other hand, Hwang(2013) defined the teacher knowledge in mathematics education and four sub-domains of the teacher knowledge. According to these four domains, Hwang(2013) developed the items on the instructional evaluation in mathematics class. From now on, based on these two study, this study was to develop the items on the instructional evaluation involving the practical knowledge. Futhermore, the final and ideal items on the instruction would be established through the reflection and comments of professionals such as mathematics teachers, professors, and researchers.

The objectives of this study were to survey the adverse reactions by Taeeumjowi-tang and to compare the tendency of symptoms by Sasang constitutional type. The clinical data for this study were based on the medical records of 78 cases collected from an oriental clinic. The major results of this survey are following: The 5.8% of Taeeum-in who took Taeeumjowi-tang showed side effects. And the 52.4% of Soeum-in and 41.6% of Soyang-in also showed side effects against Taeeumjowi-tang. They complained of excitation, irritability, restlessness, hypersensitivity, tinnitus, insomnia, upper abdominal discomfort, poor appetite, thirst, perspiration, dizziness, chest pain, tremor and evacuation troubles in common. And these adverse symptoms were similar to that by Ma-hwang. Therefore if we make a suitable medication guide for Ma-hwang based on Sasang constitutional type, it will be able to maximize the efficacy and minimize the adverse effect.

We determined the maturity and growth of the Marbled sole, Pseudopleuronectes yokohamae based on monthly sampling in the West Sea of Korea from February 2009 to December 2010. Determination of sex of P. yokohamae was by gonadal inspection, and age and growth were determined by analyzing the otolith. The biological minimum size of P. yokohamae female was 24.5 cm. The seasonal changes in the ratio of a translucent zone to an opaque zone revealed that the end of the translucent zone of the otolith were annuli formed in May once a year. We compared 8 type growth equations with several length-at-age data. By using the length-at-monthly age data of these, the calculated von Bertalanffy growth equations were $L_t=41.7(1-e^{-0.47(t+0.24)})$ for females and $L_t=32.7(1-e^{-0.75(t+0.01)})$ for males. We estimated that 24.5 cm was the total length of 2 year old P. yokohamae spawns in the cold water season from January to April, and grows to 8 years old for females and 6 years old for males in the West Sea of Korea.

The methanol extract from the aerial parts of Dictamnus albus was active in inhibiting monoamine oxidase (MAO) from the mouse brain. Activity-guided fractionation led to the isolation of four known coumarins, 7-(6'R-hydroxy-3', 7'-dimethyl-2'E, 7'-octadienyloxy) coumarin (1), auraptene (2), umbelliferone (3), and xanthotoxin (4), as active compounds along with an inactive alkaloid, skimmianine (5). Compounds 1 and 2 inhibited MAO activity in a concentration-dependent manner with $IC_{50}$ values of 0.7 and $1.7\;{\mu}M$, respectively. Compounds 1 and 2 showed a slight and potently selective inhibitory effect against MAO-B ($IC_{50}\;0.5\;and\;0.6\;{\mu}M,\;respectively$) compared to MAO-A ($IC_{50}\;1.3\;and\;34.6\;{\mu}M,\;respectively$). According to kinetic analyses derived by Lineweaver-Burk reciprocal plots, compounds 1 and 2 exhibited a competitive inhibition to MAO-B.
