Today, furniture design, which is changing and diversified, a movement to search a new formative world while reviving our traditionality is continuously proceeded, that implies a new possibility in our culture. In respect of such diversified materials, Korean traditional paper, Hanji (韓紙), has already been acknowledged with its excellence. Also, Hanji is a material that fully contains aesthetic consciousness of Korean people, accordingly, this research investigated and analyzed mainly with Sarangbang furniture among Joseon antique furniture, in order to study the possibility of Hanji decorated furniture as the objet in our interior space. This research utilized Paper cut technique (剪紙技法) among Hanji Crafts technique of expressive elements of Sarangbang furniture using Hanji, which is to make patterns and attach them by cutting out or engraving colored papers using scissors or graver to the wooden frame (白骨). Through this, this research could investigate production process utilizing Paper cut technique, also, Sarangbang furniture utilizing such Paper cut could be settled down as the objet with functional aspect and aesthetic completion in our interior space. Also, the researcher presents value of our original furniture by suggesting final output and considers that systematic researches should be conducted continuously on furniture henceforth utilizing Paper cut technique.

In this research, the test how the evaluation of the spacial image influenced by the environmental friendly elements included in the visual information, and how the selection of the sound changed depending on the characteristics of spacial image were carried out by the 40 subjects. Vast tracts of green land and the waterfront were highly preferred and impressive than the other spaces. The green music, signal with water sound and bird chirping sound were highly scored. In the frequency characteristics of the factors, the first factor was artificial sound (high at the low frequency band), the second was natural sound(uniform at all frequency band) and the third was water sound (high at the middle and high frequency band over 500 Hz) . This shows that the proposal of the sound which has the frequency characteristics fit to the spacial image should be selected for the soundscape of the target space.

본 연구는 CGI의 원리를 우리나라 초등학교 교실 수학 수업에 적용해 보고, 학습자의 사고와 행동 특성, 교사가 느끼는 긍정적인 점과 어려운 점을 분석하였다. 연구를 위해 3학년 한 학급 학생들을 대상으로 수업을 한 결과, 첫째, CGI의 원리를 적용한 수학 수업은 학생들에게 자신이 알고 있는 수학적 지식에 대하여 의사소통 할 기회를 제공해 주며, 둘째, 학생들이 수학적으로 사고할 수 있게 하고, 셋째, 이런 수업을 위해 교사는 알맞은 분위기를 만들어 주어야 한다는 결론을 내릴 수 있었다.

We have performed accelerated photo-degradation test using a 10-Sun level high irradiance $Weather-Ometer^{(R)}$ (10-Sun Ci5000) in an attempt to study acceleration and correlation between accelerated and service conditions for ink-jet ink. The accelerated test was used to predict lifetimes of ink-jet ink through the calculation of scaling factor for intensity of irradiance and duration of usage combined with estimation of lifetime distribution and inverse power model as a life-stress model. The lifetimes and acceleration factors for foreign and domestic inks were compared with each other. The results showed that the failure mechanisms and life-stress models for ink-jet ink were different among the color of ink which means that we might be in need of further study by color of inks.

Two series of new organic fluorophores such as asymmetrical 3-(benzimidazol-2-yl)-10-hexylphenothiazine derivatives 1 and symmetrical 3,7-bis(benzimidazol-2-yl)-10-hexylphenothiazine derivatives 2 have been synthesized. Electronic absorption, fluorescence, and electrochemistry measurements reveal that the electron withdrawing benzimidazole subunit directly connected to the phenothiazine core facilitates the charge transfer characters which were also verified by the theoretical calculations. Various substituents on the benzimidazole moieties can allow a fine-tuning of the LUMO energy levels of the molecules without significantly affecting the HOMO energy levels. The method provides a new route for designing ambipolar molecules whose energy levels are well-matched with the Fermi levels of the electrodes to facilitate the electron or hole injection/transfer in OLED devices.

KMRR은 잉여반응도 및 출력분포조절을 위하여 Hafnium관을 사용한다. 현재 노심해석은 핵연료집합체 단위로 균질화된 5군 군정수를 이용하여 중성자 확산코드인 VENTURE을 이용한다. Hafnium관내에 핵연료가 들어있는 특수한 조정 집합체에 대해서도 이러한 균질화된 군정수를 사용한 중성자 확산계산이 적용될 수 있는가를 조사하였다. 비교계산은 중성자 수송코드인 TWOTRAN을 사용하여 잉여반응도 및 출력 준위에 대해 수행하였다. 계산결과 현재의 균질화된 군정수를 사용하는 중성자 확산계산이 큰 오차없이 적용할 수 있는 것으로 나타났다.

The effects of the Evodiae fructus on the cardiovascular function were assessed in spontaneously hypertensive rats, and isolated preparation of spontaneously hypertensive rats aortic strip. In spontaneously hypertensive rats, intraperitoneal administration of methanol crude extract of Evodiae Fructus (0.5mg/kg) lowered aterial blood pressure which lasted for at least 4 hours. The hypotensive effect of Evodiae Fructus was more stronger with ${\alpha}-adrenoreceptor$ inhibitor(Phentholamine) and it was not affected by ${\beta}-adrenoreceptor$ inhibitor(Propranolol). The hypotensive effect of Evodiae Fructus was abolished by NAME. It is suggested that the hypotensive effect of Evodiae Fructus may be concern with endothelium-derived relaxing factor and it may be mediated through NO synthesis. Evodiae Fructus showed a vasorelaxing effect on denude aortic strip. It is suggested that Evodiae Fructus has a direct relaxing effect on vascular smooth muscle cells. Judging from above results, it was proved that hypotensive effect of Evodiae Fructus. The mechanism of hypotensive action may be concern with endothelium-derived relaxing factor and direct relaxing effect on vascular smooth muscle cells. Therefore, it is suggested that Evodiae Fructus is applicable to hypertension.

This study was conducted to investigate the effect of fertilizer composted of dam suspended particle sawdust and sewage sludge to soil properties and seedling growth. The Betula platyphylla var japonica, Zelkova serrata and Chamaecyparis obtusa were used for this study. The soil organic matter, total nitrogen, phosphorous, exchangeable calcium, magnesium, and potassium were increased with fertilizer treatment. Heavy metal concentration in soil was increased with fertilizer treatment, but the level was very low. With fertilizer treatment, growth, photosynthetic capacity, and chlorophyll concentration of seedling were improved.
