Smart window technology has become a major component of smart buildings, leading to energy savings and enhanced functionality. Smart windows work like curtains or blind screens, blocking external light sources. Smart window components employ electrochromic or photochromic materials that can selectively block sunlight when electricity is applied. The installation of low-E glass and building-integrated photovoltaics (BIPV) is being encouraged in accordance with the policy on saving building energy. To incorporate BIPV into smart windows, the transparency and colors of transparent photovoltaics must be optimized. The power sources required to operate these smart windows take advantage of the transparent color of the solar cells, which also facilitates aesthetics. Self-powered smart windows that combine electrochromic or photochromic screens with transparent solar cells suggest a promising convergent technology.

The objective of this study is to describe more positively and concretely the entity of traditional village through the quantitative and scientific analysis process using positive data. Dan-Gye, a traditional village in San-Cheong, has been populated since more than 500 years ago because of its ideal conditions for settlement. In this study, the fluctuations on the numbers of households in Dan-Gye were analyzed from the first settlement era to the present, and the transformations of housing sites and roads since 1913 were also analyzed. The results are as follows. 1) The village Dan-Gye has a history of more than 500 years, and the first inhabitants were the Ryus. As time went by, the Ryus' power became weak gradually, but the powers of the Kwons and the Parks who had flowed later into this village became prosperous to make up a prominent family village in the late period of Cho-Sun dynasty. Such powers had reached the peak in the early period of Japanese occupation, and although the powers became weak gradually after that time, those two families have overwhelmed other families in population and possession of large houses until now. But as the confucianism in every-day life fell off and the inhabitants moved to cities, the existence of a family community became meaningless. 2) The Kwons and the Parks have possessed the large parts of the village's housing sites. As time went by, the sites have been divided and fields have been changed to housing sites for the increasing families, and such division and change have been made chiefly on perimeter areas. 3) The characteristics of the road in Dan-Gye where traditional roads existed began to be destroyed by Japanese construction of new roads, and such destruction has continued due to the bank construction after a flood and the road constructions after 1970s.

Purpose: Denervation supersensitivity to 0.125% pilocarpine is an important factor in making a diagnosis of Adie’s tonic pupil. However, it generally takes several weeks for denervation supersensitivity to manifest after an injury to the nerve ganglion. We report a case of ‘acute’ Adie’s tonic pupil before the manifestation of denervation supersensitivity. Case summary: A 53-year-old man with no significant past medical history visited our clinic, reporting mydriasis of his left eye. Pupil size was 8 mm in the right eye, 3 mm in the left. Loss of both direct/indirect light reflex and light-near reflex were observed. The left pupil did not react to 0.125% Pilocarpine, but constricted in response to 1% pilocarpine. After 5 months, the pupil size did not change, but the pupil constricted in response to 0.125% pilocarpine. Conclusions: In an isolated case of dilated pupil, though the pupil did not react to 0.125% pilocarpine, with respect to the Adie’s tonic pupil, to check the manifestation of denervation supersensitivity should be needed at regular intervals.

Purpose: To report a case of an anterior fibrovascular membrane following cataract extraction and intraocular lens implantation in a patient with congenital aniridia. Case summary: A 13-year-old girl presented with congenital aniridia and cataracts in both eyes. She underwent cataract extraction by phacoemulcification with intraocular lens implantation. Six months after cataract surgery, a progressive anterior chamber fibrovascular membrane was noted in both intraocular lens and rudimentary iris. Surgical excision of the fibrovascular membrane was performed, but there was recurrence after five weeks in both eyes. Subsequent surgical intervention on both eyes involved intraocular lens explantation combined with membranectomy to prevent recurrence and phthisis. Surgical findings indicated that the fibrovascular membrane involved the retrolenticular space, and histopathological evidence indicated that the extensive fibrotic tissue originated from the root of the rudimentary iris. Conclusions: Patients with congenital aniridia should be monitored carefully for the development of intraocular fibrosis after intraocular lens implantation. If a fibrovascular membrane is noted, early surgical intervention is recommended, and the explantation of the intraocular lens should be considered during surgical intervention to prevent recurrence and complications.

Purpose: To determine the effect of cataract extraction on visual field damage in glaucoma patients with cataracts. Methods: Sixty-two eyes of fifty glaucoma patients (primary open-angle glaucoma, angle-closure glaucoma, and normal-tension glaucoma) were divided into three groups according to the MD (mean deviation) value from the Humphrey automatic visual field test. The PSD (pattern standard deviation) values were analyzed before and after the cataract surgery. Additionally, the visual acuity, intraocular pressure and the number of antiglaucomatous agents were compared. Results: All of the three groups, showed significant improvement in visual acuity. However, there was only a significant decrease in intraocular pressure at three months postoperatively. When comparing the mean MD values of each group, there was a statistically significant difference between the mild defect group and the severe defect group, but no statistically significant difference in the moderate defect group. There was also no statistically significant difference in PSD values in the any of the groups before and after cataract surgeries. Conclusions: In glaucoma patients with cataracts, there were no significant differences in PSD values before and after cataract surgery. Additionally, to perform an adequate cataract operation in advanced glaucoma patients without the progression of visual field damage, lowering intraocular pressure and improving visual acuity is helpful.

Ch'ang-Ts'al-Ts'un is a rural Village near Lung-jing City in Yen-pien Korean Autonomous Province of China. It was formed about 100 years ago by Korean Immigrants and has been developed maintaing the characteristics of traditional Korean architecture. Therefore investigating the spatial structure of this village is a meanigful work to confirm and explore one branch of Korean architecture. This study aims at analyzing the spatial structure of the village using direct data collected from the field work and indirect data from books and maps. The field work consists of on-the-site survey of the village layout, interviews of residents, observation notes and photography. Ch'ang-Ts'ai-Ts'un is located 360-370 m high above the sea level and at the side of a long valley. A river flows in the middle of the valley and relatively flat arable land exists at the both sides of the river. The location of the village related to the surrounding river and mountains suggests that the site of the village was chosen according to Feng-Shui, Chinese and Korean traditional architectural theory. The main direction of the house layouts is South-western. The village has been growing gradually until today. Therefore it is meaningful to make the village layout before Liberation(1946 A.D.) because the characteristics of Korean architecture prevailed more in that period. The area of the previous village is limited to the west side of the creek. New houses were later added to the east of the creek, forming a 'New Village'. Previously the village was composed of 3 small villages: Up, Middle and Down. Also the main access roads connecting the village with the neighboring villages were penetrating the village transversely. Presently the main access road comes to the village longitudinally from the main highway located in front of the village. The retrospective layout shows the existence of well-formed Territory, Places and Axes, thus suggesting a coherent Micro-cosmos. The boundary of imaginery territory perceived by present residents could be defined by linking conspicous outside places sorrounding the village such as Five-mountains, Front-mountain, Shin-dong village, Standing-rock, Rear-mountain and Myong-dong village. Inside the territory there are also the important places such as Bus-stop, Memorial tower of patriots, Road-maitenance building and the village itself. And inside it 5 transverse and 1 longitudinal axes exist in the form of river, roads and mountains. The perceived spatial structure of the village formed by Places, Axes and Territory is geometrical and well-balanced and suggests this village is fit for human settlement. The administrative area of the village is about 738 ha, 27 % of which is cultivated land and the rest is mountain area. Initially the village and surrounndings were covered with natural forest But the trees have been gradually cut down for building and warning houses, resulting in the present barren and artificial landscape with bare mountains and cultivated land. At present the area of the village occupied by houses is wedge-shaped, 600 m wide and 220 m deep in its maximum. The total area of the village is $122,175m^{2}$. The area and the rate of each sub-division arc as follow. 116 house-lots $91,465m^{2}$ (74.9 %) Land for public buildings and shops $2,980m^{2}$ (2.4 %) Roads $17,106m^{2}$ (14.0 %) Creek $1,356m^{2}$ (1.1 %) Vacant spaces and others $9,268m^{2}$ (7.6 %) TOTAL $122,175m^{2}$ (100.0 %) Each lot is fenced around with vertical wooden pannels 1.5-1.8 m high and each house is located to the backside of the lot. The open space of a lot is sub-divided into three areas using the same wooden fence: Front yard, Back yard and Access area. Front and back yards are generally used for crop-cultivation, the custom of which is rare in Korea. The number of lots is 116 and the average size of area is $694.7m^{2}$.

생의 기술

이규성(Kyu Sung Lee) 철학연구회 1996 哲學硏究 Vol.39 No.-

이 글은 형이상학을 단순한 이성적 추리의 산물로서보다는 생에 대한 어떤 태도를 전제하고 그 생을 어떤 방향으로 정위지으려는 인간존재의 진리로서 파악하고, 그것을 논증하려는 글이다. 형이상학은 생의 분열과 무의미를 넘어서서 모종의 통일성과 의미를 추구하는 철학적 사유의 산물 즉 일종의 생의 기술이다. 그런데 통일성과 의미는 초월적 영역으로부터 오는 것일 수도 있고 자연 내재적 영역에서 찾아질 수도 있다. 그러나 양자의 입장이 각기 자신의 논리를 가지고 있지만 궁극적으로는 정당화될 수도 없고, 또 형이상학 자체도 논리적 정당화의 문제도 아니다. 그래서 양자의 입장 중 어느 것을 선호하는가는 논리의 귀결에 의해 결정되는 것이 아니라 생에 대한 결단의 문제로 된다. 이런 문맥을 전제하고 이 글은 내재적 형이상학을 선택하고 그것이 생의 우울로부터 명랑으로의 전환을 도모하는 기술임을 주장하고자 하는 것이다. 이와 함께 생의 기술로서의 형이상학은 존재의 품격을 향상시키는 것을 의도한다. 그러므로 형이상학은 소유의 증대, 의무의 도덕의 강제를 넘어서서 존재에의 용기를 고취할 수 있다. 더 나아가 존재의 가치증대는 상품생산 사회로서의 현대사회에 대해 저항할 수밖에 없는 하나의 윤리학적 원리가 된다. 이 글이 입증하고자 하는 것은 이상과 같은 형이상학의 특성과 그 윤리적 의의에 대한 것이다.

A rare case of intracranial seeding from a craniopharyngioma is presented. A 25-year-old man underwent radical resection of a suprasellar papillary craniopharyngioma 3 months previously. There had been no clinical evidence of recurrence, however, routine follow-up MRI showed a recurrent tumor. The multilobulated metastatic craniopharyngioma was not anatomically connected to the suprasellar region, but originated from the Sylvian fissure along the former surgical route. Pathologic examination again showed papillary craniopharyngioma that had the same histological features of the previous tumor. This case signifies that direct implantation of the tumor could occur adjacent to the surgical exposure site.

인공위성 레이다 영상자료를 이용한 임분(林分)구조의 물리적 특성파악

이규성 ( Kyu Sung Lee ) 大韓遠隔探査學會 1992 大韓遠隔探査學會誌 Vol.8 No.2

최근 지구궤도상 영상레이다 시스템의 발전과 더불어 여러 응용분야에서 레이다 원격탐사자료를 이용하려는 관심이 높아지고 있다. 본 연구는 우주상공에서 얻은 레이다 영상자료로부터 얻은 레이다반사치와 산림의 특성과의 상관관계를 밝히고자 하였다. 미국 플로리다 북부 산림지대의 연구지역을 대상으로 하여 1984년 10월 우주왕복선 비행에서 Shuttle Imaging Radar B(SIR-B) 자료를 얻었다. 여러 종류의 참고자료(임분 조사자료, 林相圖, 항공사진, Landsat Thematic Mapper 자료)를 이용하여 약 400여개의 표본임분을 선정하였다. 각 임분의 물리적 특성(평균수고, 흉고직경, 수간밀도, 생체량, 하충식생량)과 그에 따른 레이다반사치와를 비교하였고 그들간에 통계학적으로 유의성이 있는 상관관계를 볼 수 있었다. 또한, 동일한 임분특성에서도 레이다반사치가 세 개의 走査각도별로 다르게 나타나고 있었다. 끝으로 최근 우리에게 인용가능한 인공위성 레이다영상자료의 종류와 특성 및 전망 등을 살펴보았다. With recent development in spaceborne imaging radar systems, there are growing interests using satellite synthetic aperture radar(SAR) data in various applications. This study attempted to identify the relationships between several forest stand characteristics and radar backscatter, measured from space altitude at three incidence angles. Shuttle Imaging Radar-B(SIR-B) data were collected over a forested area in northern Florida in October, 1984. By using various sources of reference data(forest type maps, inventory records, aerial photographs, and Landsat Thematic Mapper data), about 400 forest stands of known characteristics were carefully located in the radar data. Relative radar backscatter for the three incidence angles of SIR-B data were compared with known forest stand parameters such as mean tree height, diameter at breast height(DBH), stand density, biomass, and relative amount of understory vegetation. The results show that these stand parameters have statistically significant correlations with the radar backscatter. In addition, the SIR-B radar backscatter from a certain stand parameter turned out differently at the three different incidence angles. Finally, the types and characteristics of currently available satellite SAR data are discussed.
