Annals of the Joseon Dynasty is the authentic record of the historical facts and events taken place throughout the entire period of 472 years(25 generations, 1392~1863)described in a chronological order. The tremendous volume of the records contains the factual events taken place in almost all the fields of the Joseon Dynasty ranging from politics, economy to history of the dynasty. Not only because of its affluent contents but also with the precision of its records, it was designated as the National Treasure No. 151 in1973 by the Korean government and also registered as the Memory of the World by UNESCO in October 1997.This study is to report a exhaustive investigation results on the conservation state of annals of the Joseon Dynasty, especially Mt. Jeongjoksan edition, under the storage of the Kyujanggak in order to obtain the current condition, and thereby to estimate the any deterioration of the waxed volumes in the future. According to results of the investigation, we are going to verify damage causes of annals of the Joseon Dynasty, and to consider scientific conservation methods for the permanent preservation of invaluable cultural heritage. The major problem with the preservation of annals has arisen particularly from the deterioration of the waxed volumes of the Mt. Jeongjoksan edition. In order to provide for the counter measures for this problem, we have conducted twice investigations(first :1998~1999, second : 2003) to the internal and external conditions of waxed volumes(Annals of King Taejo~Annals of King Myeongjong).The result of the investigation has indicated that the paper quality of the some of the waxed volumes (Annals of King Taejong~Annals of King Sejong) is cracked and folded and the pages are imbedded to each other due to the hardened or congealed wax on the paper. Some of the pages are even getting moldy. And in order to detect as to whether“ there has been any deterioration progressed to the waxed books in the modern storage facility of the Kyujanggak equipped with constant temperature and humidity condition, the first investigation(1998~1999) and the second investigation(2003) have recorded the values of acidity, whiteness and moisture rate of the waxed paper, reporting an observation that there has been no difference on the measuring items. This indicates that no virtual deterioration has been progressed so far to the waxed volumes preserved in the Kyujanggak. Also, except for the causes of deterioration to the paper by insects and microorganisms, the major cause for the paper damage seems to the change of moisture of the paper caused from the alteration of the temperature and humidity of the storage environment. With this understanding in mind, we have conducted an environmental investigation on the three selected points of the storage in the aspects of the temperature, humidity, air current, $CO_2$,HCHO, and $SO_2$.It has been observed that the temperature stood at $16.9^{\circ}C~20.2^{\circ}C$ and the humidity was stable between 53%~56% during the period of the investigation. The concentration of the carbon monoxide and carbon dioxide of the storage were very similar to those in the air. These data lead to presume that there is no problem in the aspect of carbon oxidization. But the concentration of sulfur dioxide, hydrogen sulfide and formaldehyde of the storage were detected a little higher than those of standard. Therefore, we consider that it is necessary to ventilate the internal air of the store room by means of operating air purification devices.

In this study, children with MR were compared with normal children in overall production rate and production types of six semantic categories of negation. For this purpose, 10 children with MR and another 10 language-age matched normal children were selected. The results of this study were as the following: First, the children with MR showed significantly low overall production rate, compared with normal children. Two groups demonstrated signifiant differences in denial, disability, ignorance, prohibition and rejection except nonexistence. Second, in production type, the children with MR tended to use more gestures, and in comparison, normal children used more 'mixed types'.

탐지견을 활용한 목조건축물의 흰개미피해 조사 연구

정소영,Jeong, So-Young 국립문화재연구소 2010 保存科學硏究 Vol.31 No.-

Wooden structures in Korea are usually damaged by some insects such as termites, wasps, cigarette beetles, powder-post beetles. Especially, the termites inhabiting in Korea are the subterranean termites, Reticulitermes speratus kyushuensis Morimoto, that make colonies in underground, therefore it is difficult to predict and control substantial infestations in advance. Accordingly, to enable inspectors to locate the termite infestations before the extensive damage occurs, the pest management industry has begun using several elaborate tools and making the various effect to inspect areas hard to access through a visual inspection. Recently detector dogs were adopted as one of those tools. Detector dogs are useful for locating subterranean termites because they use their acute olfaction rather than vision. We also have used detector dogs to locate termites and investigated 270 buildings from 31 sites since 2007. According to the results, while 144 buildings (53.4%) were in good condition with no damage by termites, 80 buildings (29.6%) were found out to be damaged by termites through visual inspection and detector dog. So it is expected to control termites according to the conservation status if detector dogs are well trained to discriminate live termites from fecal pellets by termites.

There are several methods of pest control for the prevention of wooden cultural properties from damages caused by insects, especially termites. Those are as follows; physical control, chemical control, biological control, and integrated pest management. In Korea, we primarily use mvestigation of monitoring, fumigation, treatment of insecticidal and antiseptic chemicals, soil termiticide treatment, and termite colony elimination system. As damages by termites were detected at Eunghyanggak and Saundang of Haeinsa temple in June, 1998, we carried out monitoring with wooden device, in order to investigate damages of wooden building by termite and paths of termite invasion. According to the result of investigation of monitoring from1999 to 2002, we found that termites were inhabiting continually at forests around Haeinsa and that wooden buildings such as Saundang, Cheonghwadang were damaged by termites. So we thought that control methods such as soil termiticide treatment and termite colony elimination system would be effective. Especially, to investigate efficacy of termite colony elimination system, we carried out efficacy test of termite colony elimination system in Jongmyo during 17 months(2000.7.~2001.11.). The result of efficacy test showed that termite colony elimination system eliminated termite colonies gradually(over 12 months from installation of colony elimination system to elimination of termite colony).

목조건축물의 흰개미 방제에 대한 국외 현황조사(I) - 미국의 사례를 중심으로 -

우리나라에는 지중흰개미의 일종인 큐슈흰개미 1종이 분포하고 있으며, 흰개미 피해가 발견되었을 경우 훈증처리, 토양처리, 방충방부처리, 흰개미 군체제거시스템 등 4가지 방법을 적용하여 방제하고 있다. 그러나 점차적으로 흰개미에 의한 피해가 증가하고 있으므로 흰개미 피해가 심각한 미국, 일본 등 다른 나라의 피해 현황 및 방제 방법에 대해서도 조사할 필요가 있다. 본 고에서는 1950년경부터 흰개미 피해가 발생한 미국을 중심으로 흰개미 분포 현황 및 방제 체계에 대해 살펴보고자 한다. 미국에는 지중흰개미, 건재흰개미, 습재흰개미 등 다양한 종류의 흰개미가 분포하고 있어, 우리나라에 비해 흰개미에 의한 피해가 더 심하게 발생한다. 따라서 흰개미 피해를 조사하고 적절한 방제방법을 선택하는 것이 중요한데, 그 과정은 흰개미 피해 조사, 화학적 방제처리(토양 약제 처리, 흰개미 군체제거시스템), 건축물 유지보수, 주기적인 모니터링의 순서로 이루어진다. 그리고 분포하는 흰개미의 종류가 다양하기 때문에 흰개미 피해로부터 방제작업을 진행할 때도 흰개미의 특성을 고려하여 각각 다르게 적용된다. 지중흰개미에 의한 피해가 발견되었을 경우에는 건축물에 대한 기피성 또는 비기피성 살충제를 이용하여 처리하거나 흰개미 군체제거시스템을 이용하여 처리한다. 반면, 건재흰개미에 의한 피해가 발생한 경우에는 훈증처리,열처리 등을 통해 방제하고 있다. There are more than 2,800 different species of termites in the world, but just there is one species (Reticulitermes speratus kyushuensis Morimoto) in Korea. Once wooden structures are damaged by termites, we are applying chemical control methods such as fumigation, treatment of insecticidal and antiseptic chemicals, soil termiticide treatment, and termite colony elimination system to pest control. But in Korea, the termite infestation is gradually increasing, so it is essential to study on the present situation of termite control in US or Japan. Accordingly, in this part we have studied focusing on the case of US. In the US, there are three groups of termites : Subterranean, Drywood, Dampwood termites, and they caused more severe infestation compared with Korea. When a structure has become infested with termites, it is important that appropriate action must be taken: the chemical pest control (soil treatment, termite baiting, termite colony elimination), the modification and maintenance of buildings and the regular inspection for follow-up. And with consideration for different characteristics of termites, the process of pest control is made according to each species of termites. Most of the subterranean termite control is done by applying either termiticide to the soil or termite monitoring and baiting system around the structure. On the other hand, drywood termite control methods can be categorized as either the treatment for the whole structure or the treatment for localized area. Applications to the whole structure are done by fumigants or heat and the localized treatments are carried out with chemicals as well as heat, freezing, microwave and electricity.

온라인 재학습 가능한 RBF 네트워크를 이용한 열연 권취 온도 제어 모델 개발

정소영,이민호,이수영,Jeong, So-Young,Lee, Min-Ho,Lee, Soo-Young 대한전자공학회 1999 電子工學會論文誌, S Vol.s36 No.8

본 논문에서는 포항제철의 열연 권취 온도 공정을 제어하기 위한 방법으로 온라인 재학습 가능한 RBF 네트워크(Radial Basis Function network)를 제안한다. 새로 제안된 신경회로망 모델을 이용해 권취 온도 제어 시스템의 열전달 계수를 생성해주는 기조의 규칙 기반 계수표를 대체할 수 있다. 열연 공정 작업의 시간에 따른 변화를 고려하도록 지존의 RBF 네트워크에 부가적인 온라인 재학습용 시냅스 가중치를 도입한다. 부가적인 가중치들로 인해 이미 학습된 전체 데이터들의 특성 정보를 유지하면서 새로 들어오는 데이터들에 대해 온라인 재학습이 이루어진다. 따라서, 제안된 RBF 네트워크는 파국적 간섭(catastrophic interference)효과를 상당히 감소시킬 수 있다. 그리고 거부 네트워크을 도입하여 제어기의 신뢰도을 높일 수 있었고, 실제 현장에 적용한 실험 결과는 기존의 방법보다 평균 2.2퍼센트이상 향상된 성능을 보였다. This paper describes on-line retrainable RBF network in order to control the coiling temperature for a hot coil strip at Pohang Iron & Steel Company(POSCO). The proposed neural network can be used for improving conventional rule-based lookup table, which generates a heat transmission coefficient. To cope with time-varying characteristics of hot coil process, additional synaptic weights for on-line retraining purposes are introduced to hidden-to-output weights of conventional RBF network. Those weights are locally adjusted to newly incoming test data while preserving old information trained with off-line past data. Hence the effect of catastrophic interference can be greatly alleviated with the proposed network. In addition, rejection scheme is introduced for reliability concerns. From the experimental results applied to the actual process, it is noticed that overall control performance represents about 2.2% increase compared to the conventional one.

나노입자(nanoparticles)는 그 크기가 피부를 구성하는 세포보다 작다. 따라서 세포막을 통과하고 약물 또는 유전자를 전달하는 매개체로서의 역할에 매우 적합하며 특정 성분을 피부 속에 전달할 수도 있다. 본 연구에서는 쑥으로부터 나노입자를 추출하여 dynamic light scattering (DLS)를 통해 100 nm 전후 크기의 입자를 얻었음을 확인하였고, MTT assay를 통하여 섬유아세포에서 cell viability를 농도 의존적으로 증진시키는 결과를 얻었다. 또한, quantitative real time PCR 분석법을 통해서 COL1A1 mRNA 발현량을 증가시키고 IL-6 mRNA 발현량은 감소시킴을 확인하였다. 세포실험뿐 아니라 화장품 제형에서도 적용 가능하며, 안정함을 확인하였다. 최근 화장품 산업 동향에서 화학 성분을 배제하고 식물 유래 성분 수요가 지속적으로 높아지고 있는 반면, 식물에서 유래된 나노입자의 응용분야를 제시하는 연구 결과가 거의 없다는 한계가 있다. 따라서 현시점에서의 화장품 산업의 한계점을 극복하고자 본 연구를 통해 얻은 결과를 견주어 쑥으로부터 유래된 나노입자를 고기능성 화장품 소재로서 제시하고자 한다. Nanoparticles are substances that are smaller in size and smaller than cells that make up the skin. Therefore, they are very suitable as mediators for transmitting drugs or genes across cell membranes, and also deliver specific ingredients into the skin.In this study, nanoparticles were extracted from mugwort and particles of around 100 nm were obtained through dynamic light scattering (DLS), and the results of concentration-dependent enhancement of cell viability in fibroblasts were obtained through MTT assay. In addition, it was confirmed that the COL1A1 mRNA expression level was increased and the IL-6 mRNA expression level was decreased through the quantitative real-time PCR analysis method. Moreover, as these nanoparticles were confirmed to be stable, they can be applied not only to cell experiments but also to cosmetic formulations. While the demand for plant-derived ingredients continues to increase, excluding chemical ingredients from the recent cosmetics industry trend, there is a limitation in that there are few research results suggesting the application field of plant-derived nanoparticles. Therefore, in order to overcome the limitations of the cosmetic industry at the present time, the results obtained in this study present nanoparticles derived from Artemisia princeps (NDAP) as a highly functional cosmetic material.

난류강도의 영향을 고려한 초고층 프로토타입 모델의 풍압특성에 관한 수치 해석적 연구

정소영,이경수,한상을,Jeong, So-Young,Lee, Kyung-Soo,Han, Sang-Eul 한국강구조학회 2011 韓國鋼構造學會 論文集 Vol.23 No.6

최근 초고층 빌딩의 구조설계에 있어서 풍하중이 가장 중요한 하중요소로 다루어지고 있으며, 일반적으로 풍하중 산정은 풍동실험에 의하여 수행되어 왔다. 그러나 보다 간편하면서도 정밀한 산정방법의 개발에 대한 필요성이 증대되면서 그 방법의 하나로 수치해석적인 접근법인 전산유체역학이 이용되고 있다. 또한 CFD해석은 실제 스케일로 모델링 및 시뮬레이션이 가능하고 시간도 단축할 수 있는 장점을 가지고 있다. 그럼에도 불구하고 실제 프로젝트에 대한 연구의 역사와 검증과정이 일천하여 이 해석법에 의한 신뢰도가 낮기 때문에 그 활용은 미미한 실정이다. 따라서 본 연구에서는 기존연구에서 제시된 프로토타입 모델의 풍동실험 결과와 CFD해석을 통한 해석 결과의 비교를 통해 CFD해석의 신뢰도를 입증하며, 더불어 난류강도가 신뢰도에 미치는 영향에 대해 제시하고자 한다. Wind tunnels tests have been evaluating wind load estimation by discussing the most important design elements in very tall buildings. Such tests have some uncertainties, however, with respect to the data of the reduced model and the calculated empirical values. In contrast, CFD analysis can simulate the actual scale and shorten the time of simulation. Nevertheless, the utilization of CFD analysis is negligible because of its low reliability. In this paper, the reliability of CFD analysis will be proven by comparing the results of a wind tunnel test and CFD analysis for the prototype models shown in previous studies. The effect of the turbulence intensity on the reliability is also presented.
