Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease of unknown etiology characterized by accumulation of calcium phosphate in the submucosa of large airways and benign proliferation of bone and cartilage resulting in nodular formation. We report a case of tracheobronchopathia osteochondroplastica diagnosed by Endobronchial ultrasonography in a 56-year-old man. Chest Computed Tomography revealed thickening of tracheal and bronchial wall, and multiple nodules through whole trachea. Endobronchial ultrasonography showed numerous submucosal nodules with hetero-echogenecity in the third and fourth layers. Histopathological examination revealed nonspecific bronchitis with squamous metaplasia and metaplastic ossification. We confirmed tracheobronchopathia osteochondroplastica. The patient's symptoms were successfully treated with antibiotics and oxygen supplyment. endobronchial ultrasonography can helpful diagnosis in tracheobronchopathia osteochondroplastica.

Background: Korean type 2 diabetic patients who are frequently non-obese, may be genetically different from Western type 2 diabetics who are frequently obese. Therefore, the diabetic complications of type 2 diabetes mellitus in Korea may be also different from those of Western countries. Until now, most studies reported in Korea did not analyse the microvascular complications of type 2 diabetes mellitus according to obesity, and also the criteria in the diagnosis of microvascular complications were different in each study. We investigated the microvascular complications and its relationship with obesity, in type 2 diabetic patients visiting an outpatient clinic. Methods: The study subjects were type 2 diabetic patients visiting an outpatient clinic of Ajou University Hospital. We selected patients participating in a 75 g oral glucose tolerance test, retrospectively. Type 2 diabetes was diagnosed according to the WHO/NDDG classification of diabetes. Biochemical studies including lipid profile, plasma insulin and C-peptide levels were done. Anthropometric measurements were performed. Based on BMI (㎏/㎡), the patients were divided into the following groups: the lean group, when the BMI was less than 20 ㎏/㎡ the ideal body weight (IBW) group, if the BMI was between 20 ㎏/㎡ and 25 ㎏/㎡ in women and 20 ㎏/㎡ and 27 ㎏/㎡ in men; and the obese group, when the BMI was $gt;25 ㎏/㎡ in women and $gt;27 ㎏/㎡ in men. Results: 1. Neuropathy (45.2%) was the most frequent among the microvascular complications, and the frequency of retinopathy was 15.1%, and that of nephropathy was 4.9%. Within 5 years of diabetes duration, the frequency of neuropathy, retinopathy, and nephropathy was 43.2%, 11.8%, and 2.9%, respectively. 2. Glycosylated hemoglobin (HbA_(1c)) and fasting blood glucose levels were not different among the three groups. Beta cell function{Δ (insulin 30min - insulin Omin)/Δ(glucose 30min - glucose 0min)} was the highest in the obese group. However, beta cell function(ΔI/ΔG) divided by the basal insulin level, considered insulin resistance, was not different among the three groups. 3. Within 5 years of diabetes duration, retinopathy tended to be the most frequent in the lean group, whereas neuropathy tended to be the most frequent in the obese group, and body mass index influenced the retinopathy and neuropathy, statistically significantly. Conclusion: Diabetic neuropathy was the most frequent among microvascular complications of type 2 diabetes mellitus in our study subjects. At the time of presentation within 5 years of diabetes duration, the lean group of type 2 diabetics had a tendency of the more frequent retinopathy, the obese group had a tendency of the more frequent neuropathy. These results suggest that type 2 diabetes mellitus in Korea is also not a single disease entity, as in Western countries and is a heterogenous group of disorders with a diversity of microvascular complications. However, the more studies about this will be required.

This paper presents design and implementation of an information retrieval system for a large volue of an image database. Our system supports three kinds of queries: attribute-based queries, keyword-based queries, and color-based queries. The attribute-based query is the most-typical query that finds target images based on their attribute values. The keyword-based query is to find target images by referring to their description information their attribute values. Finally, the color-based query is to search for target images by comparing the colors of a query image with those of images in the database. In this paper, we presents the system architecture and approaches adopted in our system for supporting the above three queries effectively and efficiently. We also discuss the user interface of our system that enables users to manipulate our system easily and conveniently.

A residential enviroment have a role as important space in which men are live. This study is focussed to compose the space of individual housing garden through a field survey and questionaires. This paper is intended to provide the basic research materials that presents the direction of composition of traditional korean housing garden. The results of the study were summarized as follows; 1) Through comparing western house style with korean's, housing width per a person is in rank of below and further, density of building is in high level. Therefore, it is difficult to make composition of variety as to outdoor space. 2) As to concern about space composition of individual housing garden, in korean style everyone wants a garden with many trees, western and japanes's does one with lawns. 3) The most used materials at individual housing garden appeared that by orders tree, garden stone and water etc. 4) Recently, an individual housing garden trends to make a space composition of singular. As show above, gradually the composition of individual housing garden loses his tradition and identity and also, is changed as a singular space. So, this related much studies will be pursued in the field of landscape architecture.

Since the Korean speech can be phonetically classified according to the characteristic and structure of its pronunciation. Korean syllables are divided into the phonemes such as consonants, vowels, and end consonants. So, both the processing time and the signal data can be reduced by analyzing the phonemes instead of the isolated speeches. In this paper, we use the linear prediction coefficient and cepstrum coefficient at the parameter, and use ltakura-Saito distance measure as the similarity measure. First, in order to obtain the similarity in phonemes of an isolated speech, we study the acoustic similarity between the frame and its adjacent frame serially, and show, that the similarity is found in the interval of the similar phoneme and the dissimilarity is found in the interval of transition of the phoneme. In addition, after taking the single frame inside an isolated speech, we compare the parameter of the frame with the different isolated speech serially for the search of the same phoneme in the isolated speech. It turns out that the same phonemes have similar acoustic characteristics. Finally we obtain the similarity measure of each phoneme by comparing the same phonemes of two different isolated speeches. Furthermore, we also compare with phoneme with different phonemes. As a result, we obtain that the similarity is found between the same phonemes even though the phonemes are in the different isolated speeches.

全北大學校 德津캠퍼스의 綠地空間 計劃에 關한 基礎的 硏究

崔萬峰 全北大學校 1983 論文集 Vol.25 No.-

This study was carried out for the purpose of seeking the fundamental direction for open space planning of the Duckjin campus, Jeonbug National University. The author investigated the natural situation of the Duckjin campus and inquired into the natural and functional conditions of the campus. The results of the investigation and inquiry can be summerized as follows; 1. Results of investigation 1) The Duckjin campus(386,000㎡) is composed of 990,000㎡, the First Region notified for facilities and about 396,000㎡, the Second Region and stands between the hilly area(26-57m above sea lavel) and flatland contiguous to a residential area at its northwest side. It is a good location for traffic because the four-lane road to Gunsan runs about 100m off the campus. The campus landscape gives a lot of effects on the city environment, too. 2) In the viewpoint of the scope and the prospect from the campus, the University stands adjacent to the Lake Duckjin and, in the north, against the background of the Mt. Gunji, the experimental plantation affiliated to this University, and there are Jeonju industrial complex in the west, especially, it commands a fine view over the natural landscape of Mt. Wansanchilbong and Mt. Moak in the south. So these mountains must be introduced into the campus as prospects. 3) Soil is composed mainly of the sand and sandy loam, and the physical properies of the soil are generally good. The pH of the soil seems to be profitable for plant growth as the acidity or seek acid. But, the more organic fertilizer for planting must be supplied, because the O.M.(%), available P_2O_5(ppm) and cation exchange capacity(C.E.C) are very poor. 4) For the climate conditions, annual air temperature is 12.8℃, the highest of the year is 25.9℃ of August, the lowest is -0.9℃ of January, the range of air temperature of the year is very large as the 26.8℃. The highest and the lowest air temperautre of the last 10 years are respectively 37.2℃ and -14.2℃. These can influence terribly to growth of plants. Annual mean of related moisture of atmosphere is 73.6%, the precipitation is 2,330㎜ during a year, and then, the range of annual precipitation is as much as 259.2㎜. Also, the precipitation of July and August of the year, is more than that of the others, but the period from the December until March of next year is shown as very dried season. 5) One hundred and nineteen species compose the campus gardens. Most of these species are the deciduous 65, the next is the conifers 35 species, and the least species are the evergreen broad-leaves 19. With 81 species the College of Agriculture has more species than any other college. Commom species among fifteen campus garden are 38, which are 18 conifers, 3 evergreen broad-leaved and 17 deciduous. 6) For the street trees, ginkgo, fir, flowering cherry and yellow poplar are planted on two streets, hymalayan ceder-tree on one street, and weeping willow on 5 streets. The hymalayan ceder trees planted on the right and the left side of main entrance street of University from the gate to the rotary garden look very good for the meaning of harmony plantings for the evergreen color rather than for he functions of street trees. And then, the age and the number of the other street trees are so young and so small that there are very limited characteristic for their meaning and functions in campus landscape. 7) The other elements composing the landscape of the Duckjin campus except the trees and lawns described before are two ponds, 2 pergolas, the gate of University, one fountain, and one leopard statue which is constructed in front of the main building of the University. The other things are only some benches and wast baskets etc.. The facilities which can be the symbols of history and trait on of the University and the landmarks of it are very poor. 8) The results of the questionnaire to the students on the landscape of the Duckjin campus can be summerized as follows; (1) On the subject of campus beauty, 58.5% of the students replied that the campus is not beautiful, while 10.6% of the students replied that the campus is beautiful. At the gardens belonged to each college, more than 50% of surveyed students replied that they do not feel their satisfaction. For the reason of dissatisfaction on natural environment of the campus they opint out unreasonable arrangement of buildings(44.4%) and landscape planning. But the students who satisfied with them answered as the reason for the beauty of lawns. (2) Main resting places which they used during summer are class room(31.6%), lawn(29.9%), vicinity of classroom(22.0%), forest(14.7%) etc.. What are needed for them as elements of landscape are first, more forest(78%), and next are orderly lawn(2.7%), flowering plants and flower bed(8.2%), bronze statue or symbol tower and statues(3.8%), pond and fountain(4.2%), and the arbor(2.5%) etc. (3) Most of the students want to have the more naturalistic campus streets(77.8%), and as to the street planning of Duckjin campus one half of the students replied that it is good(51.3%), but other students want to have the direct roads between Home Economics Building of Educational College and the Library, the Forestry Building and Engineering College, and then the majority of the students(80.4%) wanted to have roads for a stroll road in the campus. (4) Their preference for the street trees are as follows; ginkgo tree(16.8%), willow tree(15.7%), maple tree(12.9%), cherry tree (11.9%), ceder tree(10.5%), acacia tree(8.2%). (5) The ginkgo tree marked the top as a symbol tree of the University(18.9%) next is zelkova tree(14.7%), and then korean pine(13.2%). And symbol flowers are magnolia(13.4%), lotus(13.4%) and camellia (13.4%). 2. Principles of planning On the basis of the results of the investigation and questionnaire into the natural and functional condition of the campus, the author can present some fundamental directions for open space planning of the Duckjin campus as follows; 1) The first thing to be considered, in campus land use planning is the conservation of the beauty of nature, and the next thing is, in an unavoidable case, to use efficiently and naturally the environmental condition. 2) It's desirable to make open space planning in the viewpoint of majority of the campus space users, especially of the students and the professors rather than in the viewpoint of the university authorities. 3) In designing the general landscape of the Campus, the sky line of campus should have the rhythmmical varieties, the facilities should show the landmark in the tradition and locality of the country, and the space for campus life should be established in the landscape of functional and esthetic view point for the campus use of students. 4) The plan for the campus street should consider not only its function but also its comport to the passengers. Also, it must rationally seperate the vehicles from pedestrians and service road. In selecting street tree species it should simultaneously consider the characteristics of the campus streets and the suitability for the various functions of street trees. 5) There should be more lawns, groves, pergolas and green strolling streets as an outdoor space for talking, thinking, resting and recreation. Also statues, sculptures, stones, pagodas, towers, pools fountain and flower beds are the other necessary elements for open space landscape in the campus space. All necessary parts of visible campus landscape should have a harmonious relationship with the rhythmmical skyline of the campus. 6) The fundamentals of campus planting are to make the campus harmonized with good forests, to give us seasonally changeable varieties and to supply us the dynamic activity space and the statical resting place. The herbaceous flowers should be selected in the first place of the trees flowers for planting, and in case of shade trees, a lot of large trees should be planted as many as possible and should be planed to make a green campus during the short period. 7) About 5 percentage of total construction cost should be available for the annual budget for landscape. And then landscape architects should be employed to systemically supervise the campus landscape.

天然記念物 指定樹의 現況과 管理實態 및 그 對策에 關한 硏究 : 全北地方의 天然記念物을 中心으로 Special reference to trees designated as natural monuments in Chonbuk Province

崔萬峰,李奎完 全北大學校 附設 都市및環境硏究所 1992 都市 및 環境硏究 Vol.7 No.-

This study was carried out the learn present status of trees designated as natural monuments and how those are managed in Chonbuk Province. The trees of natural monument in Chonbuk Province belong to 9 families and 15 species located in 17 districts. Growth condition was relatively good, but not the management condition requiring protection and better management services. The results of this study suggest a countermeasure limiting the land use and protecting the plant ecosystem near natural monuments, thus demanding to study those natural monuments further scientifically and also to inform the importance of natural monuments to the public.
