This study intends to understand the dramatic characteristics of architectural spaces analysed in the aspects of the user. Architecture itself is a union of equal and homogeneous static spaces when it's not related to the user, but considered with the user's continuous and undetermined movement, it will finally be completed as ‘real architecture’. To explain this, the relationship between user and architectural spaces should be set. ‘Expressive plot' is that, becomes an expressing formula which can give characteristics on each type of architecture. Conception of plot is brought in an analyzing formula to bring expressive plot into existence. Expressive plot consists of movement-space plot and movement-volume plot, and there are 5 types of expressive plot; simple contiguous expressive plot, intersectional contiguous expressive plot, contemporaneous consolidatory expressive plot, main and subordinate expressive plot, and intricate and intermittent expressive plot. Through above study, expressive plot are applied to Korean traditional houses.

This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.

The effects of Laminaria japonica fucoidan extract (LJFE) on the biochemical parameters of lipid-related function were investigated in liver and serum of CCl_(4)-treated rats. LJFE of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 14 days. On the day 15, 3.3 ml/kg of CCl_(4) dissolved in olive oil (1:1) was injected 12 hours before anesthetization. We examined the lipid-related functions and enzyme activitys by measuring the levels of total cholesterol (TC), triglyceride (TG), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in serum. The results showed that CCl_(4) treatment increased the high values of TG, LDH and ALP decreased the low values of TC but LJFE pretreatment decreased the high values of TG, LDH and ALP to the low values, increased the TC. It was suggested that LJFE can be used as the potential candidate for the lipid-metabolism natural supplement.

Diabetes Mellitus (DM) is a syndrome accompanied with the abnormal secretion or function of insulin, a hormone that plays a vital role in controlling the blood glucose level (BGL). Type 1 and 2 DM are most common form and the prevalence of the latter is recently increasing. The aim of this article was to assess whet her Type 2 DM could act as a predisposing risk factor on the pulpo-periapical pathogenesis. Previous literature on the pathologic changes of blood vessels in DM was thoroughly reviewed. Furthermore, a histopathologic analysis of artificially-induced periapical specimens obtained from Type 2 diabetic and DM-resistant rats was compared. Histopathologic results demonstrate that the size of periapical bone destruction was larger and the degree of pulpal inflammation was more severe in diabetic rats, indicating that Type 2 DM itself can be a predisposing risk factor that makes the host more susceptible to pulpal infection. The possible reasons may be that in diabetic state the lumen of pulpal blood vessels are thickened by atheromatous deposits, and microcirculation is hindered. The function of polymorphonuclear leukocyte is also impaired and the migration of immune cells is blocked. leading to increased chance of pulpal infection. Also, lack of collateral circulation of pulpal blood vessels makes the pulp more susceptible to infection. These decrease the regeneration capacity of pulpal cells or tissues, delaying the healing process. Therefore, when restorative treatment is needed in Type 2 DM patients, dentists should minimize irritation to the pulpal tissue under control of BGL. 당뇨(Diabetes Mellitus)란 혈당을 조절하는 인슐린의 분비나 기능에 장애를 야기하는 질환으로 인슐린 의존성 여부에 따라 제 1 형과 제 2 형으로 분류된다. 본 종설은 최근 증가 추세에 있는 제 2 형 당뇨가 치수 치근단 병소의 병인 과정에 전구 위험 요인으로 작용할 수 있는지를 평가 하고자 문헌고찰을 통해 당뇨의 병인 과정에서 특징적으로 나타나는 혈관 합병증에 관해 알아보고, 부가적으로 제 2 형 당뇨 쥐 모델에서 인위적인 치수감염 후 얻은 치근단 조직의 조직병리학적 분석을 시행하였다. 조직학적 관찰 결과 제 2 형 당뇨 쥐에서 대조군에 비해 치수 치근단 병소의 크기가 증가하였고, 치수 염증 반응도 심하게 나타난 것으로 보아 당뇨 자체가 숙주를 감염에 취약한 상태로 만드는 전구 위험요소로 작용하였음을 알 수 있었다. 이러한 이유로는 첫째, 당뇨 시 전반적으로 나타나는 혈관 내 죽상 침착(atheromatous deposits)에 의해 혈관 내벽의 두께가 두꺼워져 미세 순환의 장애는 물론 탐식 세포의 기능 저하, 면역 세포의 혈류 이동이 차단되어 치수 감염 시 쉽게 치근단 병소로 이환될 가능성이 높고, 둘째 치수 혈관에서 특징인 측부 순환(collateral circulation)의 부재에 따른 살균성 다형핵 백혈구의 활동 억제를 포함한 미세 혈관계의 취약성으로 인해 치수 조직의 재생능이 저하되어 추가적인 감염원의 공격에 대한 방어 및 치유 저하를 더욱 심화시키기 때문인 것으로 사료된다. 따라서 제 2 형 당뇨 환자의 수복치료 시 치과의사는 당뇨 조절 하에서 치수 조직의 자극을 최소화하기 위한 세심한 처치가 필요하다.

Although the importance of good conservation of historic sites including ancient royal tombs is well aware, still not much attention has been paid for the facilities and systems to preserve those historic sites, which includes precious artifacts as wall paints and carved works, etc. Even the general understanding about the environment of the underground space of tombs is not satisfactory. In Korea, researchers have recently begun addressing the above issue and are making efforts to develop suitable HVAC(heating, ventilating and air-conditioning) systems for conservation of tombs. An experimental investigation was carried out to study the behavior of the HVAC system installed for a tomb. This tomb resembles in size and shape the original stone built tomb of Baek-je Dynasty, which dates back to 6th Century in southwest part of Korean peninsula. In this study, an HVAC system for a tomb(D×W×H=1.3m×3.0m×1.2m) was installed to maintain sui표 indoor conditions for conservation of tomb. The temperature and humidity inside the tomb were measured different of the setting. Finally, performance of the HVAC system is presented and discussed.

박정섭,박진우,김종범,이현정,박정우,최금찬 동아대학교 환경문제연구소 2006 硏究報告 Vol.28 No.1

We have developed UV/TiO₂ photocatalytic oxidation combined process to control odor and VOCs in industrial applications. Three types of individual processes are introduced to test of their ability to increase treatment efficiency. Odor and VOC gases such as ammonia, hydrogen sulfide, formaldehyde and toluene are used for target gas. UV/TiO₂ photocatalytic oxidation combined process with activated carbon was excellent among the three types processes without relation to gas species. It will promise that this new type UV/TiO₂ photocatalytic oxidation combined process can apply industrial applications to remove odorous gases from the emission source. 본 연구에서는 대표적인 악취물질과 VOCs 의 처리 를 목적으로 UV 광촉매산화 복합공정을 이용하여 암모니아와 황화수소 그리고 포름알데히드와 툴루엔의 제거율을 높임으로써 산업공정 등에서 UV 광촉매산화 복합공정의 적용가능성을 검토하였다. 현단계까지는 악취물질의 각 물질별로 전환효율은 낮으나, 본 연구에서 제작된 UV 광촉매산화 복합공정은 악취 물질과 VOCs가 많이 발생되는 산업현장내 근무자로부터 악취물질과 VOCs등 각종 대기오염물질 저감을 위한 장치로서 실용화 가능성을 기대할 수 있다.
