본 논문은 극장이나 공연장에 설치된 CCTV 혹은 캠코더를 통해 입력받은 영상으로부터 패턴비교를 이용해 관객의 수를 카운팅하는 방법을 제안한다. 극장이나 공연장의 환경은 주로 어둡고 관객의 수가 많기 때문에 기존의 객체 검출에 의한 방법으로는 정확한 실시간 카운팅이 어렵다는 문제점을 가지고 있다. 따라서 본 논문에서는 극장이나 공연장의 좌석이 고정되어 있다는 점을 이용해 각 좌석마다 관객이 존재하지 않는 기준영상을 획득한 후 카운팅 하고자 하는 입력 영상의 동일 좌석 영상과 패턴비교를 이용해 각 좌석에서 관객의 유무를 판단한다. 특히, 본 논문에서는 기존 방법들이 지닌 조명 변화이나 잡음에 민감한 문제를 해결하기 위해 상호 보완적인 성능을 보이는 두 가지 특징인 크기투영과 Walsh-Hadamard Kernel에 기반한 패턴비교 방법들을 효과적으로 결합함으로써 조명이나 잡음의 영향을 최소화하고 정확한 카운팅을 가능하게 한다. 제안된 방법은 실제 극장에서 획득한 영상에 대한 실험을 통해 정확한 시스템 성능을 검증하며, 제안된 방법을 주차장에서 빈 주차공간을 확인하는데 적용해 봄으로써 다른 분야로의 적용 가능성을 확인한다.

가뭄은 주요 자연 재해 중의 하나이다. 가뭄 파악을 위하여 주로 강우량과 같은 기상자료를 주요 입력 자료로 활용하여 분석하고 있으나 이러한 기상 자료는 한정된 기상 관측소로부터 얻어진 점자료에 해당된다. 따라서, 기상자료를 이용한 분석에서는 시간적 혹은 공간적으로 원하는 자료의 제공이 원활하게 이루어지지 않을 수 있다. 원격탐사 자료는 가뭄분석을 위하여 기상자료에서 포착할 수 없는 이러한 문제점을 보완하기 위한 자료로 활용될 수 있다. 따라서, 본 연구에서는NOAA 위성에 탑재되어 있는 AVHRR 센서로부터 얻어지는 자료를 이용하여 가뭄 파악을 위한 분석을 실시하였다. 특히 본 연구에서는 NOAA/AVHRR로부터 얻어진 식생지수(NDVI)와 이로부터 얻을 수 있는 식생상태지수(VCI)를 이용하여 가뭄 분석을 실시하였으며, 이들 지수는 가뭄으로부터 기인된 식생 스트레스를 파악하는데 유용하게 이용될 수 있음을 알 수 있었다. 본 연구를 통하여 가뭄에 대한 시간적, 공간적 특성을 파악하는데 위성자료가 유용하게 이용될 수 있음을 알 수 있었으며, VCI를 통하여 가뭄 지역도 작성이 가능함을 보여주고 있다.

The purpose of this study is to seek for a direction of child-care development through the basic concepts of home economics which have taken charge of much parts of the studies in child-care in the early years. When the problem of child-care is studied in view of the developmental process or the basic concepts of home economics, it is summed up as follows; First, on the basis of human ecological approach, when we study child-care, it needs to emphasize the mutual relationship between the macro-environment in connection with home and child-care. The study of child-care have to find out the relationship between the micro-environment in connection with children and the macro-environment in connection with home. And on the basis of this study, we must endeavor to build up the desirable environment of child-care. Second, on the basis of the concept of Institutional household, we mud be concerned about the developmental stages of young children, and emphasize 'the principle of love and care'. This means that the institution of child-care must be considered as a place which enlarges the merits of home and complements the defects of home through the strengthener of the function of home. Third, on the basis of healthy family, child-care service must support and complement the function of bringing of home in view of 'total healthiness of home'. Child-care service must be offered to be able to be chosen according to the total conditions of family such as the employment of mother, the family life cycle, the life style, the socioeconomic status of family.

We desperately recognize from the economic situation in IMF crisis that only competive goods and serviced. It is anticipated that this difficult situation will probably be continued till 1999. Therefore, it is necessary to think over real aspects of eating=outdoors in IMF period and to provide an opportunity to confront with this crisis. Analysis a recent tendency of domestic eating-outdoors business, there appears, first of all, dual types of eating-outdoors; the one is a sort of 'Cost Sale', which provides some special menu with lowest prices, and the other is a type of 'Family Restaurant', which regards the atmosphere of the place as one of the most essential elements. Both types are getting more popular today. As the result, neither of the alternative cannot recover the current Depression. It is natural that no other conditions can compete with good tastes, fancy atmosphere, and good prices. As a matter of fact, however, it is quite difficult to run this type of bussiness adjusted the above whole conditions. Therefore owners of eating-house must decide to run either ' Cost Sale' or 'Family Restaurant' first and investigate some problems and conditions accordingly. In ane way, the owner intensively visits to some eating houses which is similar style in size and management to that of his style in size and management to that of his and look over what is good and what is bad Right after this investigation, it is efficient for he or she to improve his or her business style in size and management in a short period. It is helpful to check some complements; improvement of signboards, cleaning up of the interior, selecting suitable menu, adjusted prices, tastes, and service quality etc. Although eating-outdoors business is hard hit by IMF, We hope that it would rapidly be brisk in 2000, becaused by that time the basis of each industry would be high qualified, and rich technology would be accumulated.

Introduction: Accurate diagnosis and treatment planning are very important for orthognathic surgery. A small error in diagnosis can cause postoperative functional and esthetic problems. Pre-existing 2-dimensional (D) chephalogram analysis has a high likelihood of error due to its intrinsic and extrinsic problems. A cephalogram can also be inaccurate due to the limited anatomic points, superimposition of the image, and the considerable time and effort required. Recently, an improvement in technology and popularization of computed tomography (CT) provides patients with 3-D computer based cephalometric analysis, which complements traditional analysis in many ways. However, the results are affected by the experience and the subject of the investigator. Materials and Methods: The effects of the sources human error in 2-D cephalogram analysis and 3-D computerized tomography cephalometric analysis were compared using Simplant CMF program. From 2008 Jan to 2009 June, patients who had undergone CT, cephalo AP, lat were investigated. Results: 1. In the 3 D and 2 D images, 10 out of 93 variables (10.4%) and 11 out 44 variables (25%), respectively, showed a significant difference. 2. Landmarks that showed a significant difference in the 2 D image were the points frequently superimposed anatomically. 3. Go Po Orb landmarks, which showed a significant difference in the 3 D images, were found to be the artificial points for analysis in the 2 D image, and in the current definition, these points cannot be used for reproducibility in the 3 D image. Conclusion: Generally, 3-D CT images provide more precise identification of the traditional cephalometric landmark. Greater variability of certain landmarks in the mediolateral direction is probably related to the inadequate definition of the landmarks in the third dimension.

Ornithine decarboxylase (ODC) is a rate-limiting enzyme in the biosynthesis of polyamines, which are essential for cell growth, differentiation, and proliferation. This report presents the characterization of an ODC-encoding cDNA (SlitODC) isolated from a moth species, the tobacco cutworm, Spodoptera litura (Lepidoptera); its expression in a polyamine-deficient strain of yeast, S. cerevisiae; and the recovery in polyamine levels and proliferation rate with the introduction of the insect enzyme. SlitODC encodes 448 amino acid residues, 4 amino acids longer than B. mori ODC that has 71% identity, and has a longer C-terminus, consistent with B. mori ODC, than the reported dipteran enzymes. The null mutant yeast strain in the ODC gene, SPE1, showed remarkably depleted polyamine levels; in putrescine, spermidine, and spermine, the levels were > 7, > 1, and > 4%, respectively, of the levels in the wild-type strain. This consequently caused a significant arrest in cell proliferation of > 4% of the wild-type strain in polyamine-free media. The transformed strain, with the substituted SlitODC for the deleted endogenous ODC, grew and proliferated rapidly at even a higher rate than the wild-type strain. Furthermore, its polyamine content was significantly higher than even that in the wild-type strain as well as the spe1-null mutant, particularly with a very continuously enhanced putrescine level, reflecting no inhibition mechanism operating in the putrescine synthesis step by any corresponding insect ODC antizymes to SlitODC in this yeast system.

Population ecology of Palmaria palmata is described from the intertidal zone of Digby Neck and adjacent islands of Nova Scotia. The primary objectives were: to evaluate the difference in habitat specialization and population structure of P. palmata between harvest and non-harvest shores, and to characterize differences in thallus structure and frond sizes between epilithic and epiphytic populations. Harvest shores were gently sloping boulder fields with boulders typically about 0.5-1.0 m with dense cover of P. palmata on many of the rocks. Non-harvest shores (with or without P. palmata) consisted of boulders that were smaller or larger than harvest shores, or bedrock; when P. palmata was present on nonharvest sites it was typically epiphytic on other algae (e.g., Fucus spp., Mastocarpus stellatus, Devaleraea ramentacea). Harvestable epiphytic populations occurred only in high current areas. While there was little difference in average cover of P. palmata harvest and non-harvest shores ($31.2{\pm}13.7%$ vs. $19.4{\pm}7.3%$, mean ${\pm}$ standard deviation [SD]), the cover of P. palmata on harvest shores was highly skewed such that individual boulders often had >90% cover while adjacent rocks had little. Frond length of large fronds was greater on harvested shores, and mean frond density ($g\;m^{-2}$) was three times higher than the mean density on the non-harvested shores. Frond lengths of entire epiphytic and epilithic frond complements of 119 thalli from harvest beaches showed no difference in mean size of the largest fronds, and no difference in frond number per holdfast when epiphytic and epilithic thalli were compared.
