Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

계층적이고 반자동적인 비디오에서의 객체 추출 방법

박현재,강행봉 가톨릭대학교 자연과학연구소 2001 자연과학논문집 Vol.22 No.-

객체 기반 압축 기술은 MPEG-4에서 이용되는 기술로 객체와 배경을 따로 압축하는 방법이다. 이 방식은 압축률을 높임과 동시에 객체들간의 재합성 및 검색 등에도 이용할 수 있는 장점이 있다. 하지만, 활발한 연구에도 불구하고, 객체와 배경을 완전하게 구분해내는 알고리즘은 아직 개발되지 않고 있다. 본 논문에서는 자동화에 어려움이 있는 객체 추출 기법을 사용자의 상호 작용에 의한 반자동적인 방법으로 추출하는 방법을 제안한다. 이 방법에는 M-RSST를 이용해 공간적인 분할을 실시한 뒤에 모션 정보를 이용해서 분할된 영역들을 합병한다. 그 후 BPT에 의해 영역의 크기를 조절하며, 사용자가 원하는 영역을 선택하게 함으로써 객체 추출 과정을 간략하게 한다. Object-based coding has become one of the most actively researched areas in the past years because it can increase transmission-rate remarkably. Object-based coding system requires object extraction skill. The object extraction skill enables the system to efficiently compress pictures and to synthesize or edit pictures and videos. It can be useful in many other areas as well. While the research of the object extraction has been advanced, the algorithm, which extracts the object from its background, has not been extensively researched yet. In this paper, we propose a new semi-automatic object extraction approach for the algorithm. This proposed algorithm utilizes a user's actions to precisely extract foregrounds. This algorithm uses spatial segmentation based on color similarity and temporal segmentation to decrease the number of a user's operations. Spatial segmentation performs M-RSST(Multi-resolution Recursive Shortest Spanning Tree) followed by construction of BPT(Binary Partition Tree) of the image. M-RSST divides an image into several regions and BPT enables a user to select regions which he or she wants. Temporal segmentation is performed to merge regions that have similar motion.

To compare 5-fluorouracil plus epirubicin (FE) to 5-fluorouracil plus cisplatin (FP) chemotherapy as adjuvant therapy for patients with resected gastric cancer. Between August 1995 and March 2000, 46 patients with completely resected gastric cancer received six courses of FE (5-fluorouracil 1000mg/m2/day, D2-D5, epirubicin 70mg/m2, D1) or FP (5-fluorouracil 1000mg/m2/day, D2-D5, cisplatin 70mg/m2, D1) chemotherapy. The 23 patients were assigned to each treatment group. A total of 127 courses of treatment were given both FE and FP group. The FP group tended to show more risk of overall death rate. But there were no differences between FE and FP groups in terms of overall survival or disease-free survival. Both treatment arms were generally well tolerated to chemotherapy. We concluded to be no significant differences between FE and FP groups in terms of overall survival or disease-free survival. To define the efficacy of adjuvant chemotherapy for gastric adenocarcinoma, further prospective randomized trials with large number of patients should be warranted.

土川芎과 日川芎의 效能 및 品質比較에 關한 硏究 (2) : 두 유형의 천궁과 천궁 - 당귀 배합시의 혈관 이완효능 Vascular Relaxant Effect of Cnidii rhizoma and Cnidii rhizoma - Angelicae radix Compound

李項雨,趙顯國,朴涌基 대한본초학회 1999 大韓本草學會誌 Vol.14 No.1

In order to investigate the vascular relaxant effect of Ligusticum chuanxiong, Cnidium officinale and Angelicae radix mixed with each of them, we examined with physiography using thoracic aorta of rats. Samples were prepared to be divided Ligusticum chuanxiong (TC), Cnidium officinale (IC), TC removed oil (TCRO), oil extracts from TC (TCO) and IC (ICO), and Angelicae radix (D) mixed with TC (TC/D), IC (IC/D), and TCRO (TCRO/D). From norepinephrine and phenylephrine induced vascular contraction, all the samples had relaxant effect. IC was more effective vascular relaxant capacity compared to TC, however, as removed oil from TC (TCRO) the relaxant capacity was markedly elevated and higher than that of IC. Mixing the Angelicae radix, relaxant effect between TC/D and IC/D was that TC/D was more effective vascular relaxant capacity than that of IC/D. Whereas there was not relaxant effect in TCO and ICO, and TCRO/D was declined in relaxant rotio compared to TCRO. Based on these results, it is suggested that Angelicae radix is very effective material to elevate the vasodilation effect of Ligusticum chuanxiong and Cnidium officinale.

This research has incorporated a postal survey from the principals, nurse-charging teachers and nurse-teachers of the fiftyfive elementary, middle and high school in Yang-pyeong county area where its supplementary rate nurse-teachers is less than adequate. It is to analyse the current status of the school health service in the area and to come out with a plan to improve the school health program through the participations of the health related experts of the local community. The survey was done in the two months of periods of April to May of 1994. The result of the survey follows. The student population in the Yang-pyeong county area is 13,998 and the school employee population is 904 which counts for about 19.2% of the whole population of the area. However, the supplementary rate nurse-teachers is only 10.8% (4 in 5 schools) which is very low in terms of relativity. School health committee only exist in 17% of the whole number of schools in the area and 50 of school health commitee answered that their activity do not meet the adequate level. Only 54.3% of the whole school numbers has included the shool health finance in their financial plans and the amount set for school health finance is about 500,000 wons (100,000~1,600,000 wons). 64.9% of the schools in the Yang-pyeong county area have the permanent nursing room established in the school. But, often than the equipment for a simple physical examinations, their supply of the health related equipments are less than adequate. Particitations of school doctor in the school health service is at only 67.6% which pretty much include only the physical examinations. Nurse-charging teachers consider their utmost important role is to teach health education but, they answered that they spent most of their times and efforts on physical examinations & immunizations. The average number of students visition to the nursing room is 2.5 persons and complains for basic discomfort as headache, concussion, stomachache and indigestion problems and usual pills used are the analgesics and digestives. Physical examination is done in the most schools every year but, 51.4% of nurse-charging teachers answered the physical examination does not really help. About the emergency treatment ability, 75.7% reports that both manpower & equipment are short. The school food services are present in only 8 schools (21.6%) but, 89.2% of nurse-charging teachers answer that there is a definite need of the food service. The survey says that the utmost important environmental health and safety factors are the traffic accidents followed by improper heat system, lighting, the stools and desks that do not consider the student physical status. The overall evaluation of school health program reports that there are adequate physical examination, immunization, environmental hygiene, and management of safety but, on the other hand, health education, health councelling & management of nursing room are not managed properly. The principals of the survey pool report shortage of public agency support, lack of understanding of school health, shortage of nursing equipments and school health finance as the barrier factors of school health. The nurse-charging teachers report on the same questions as their less than qualitifying expertise, extraload of work upon the nursing affairs, shortage of nursing equipments & school health finance. The head masters & nurse-charging teachers answered that they are desperate for the meetings of nurse-charging teachers, construction of school health councelling system & training education in order to improve school health and if these are available, they will actively participate in them. After the careful analysis of the survey result, it is apparent that through thr relations of the manpowers, establishment of community-oriented school health is definitely in need rural area where there is low supplementary rate of nurse-teachers and poor school health environment.

CORBA 디자인 패턴에 관한 연구

소프트웨어의 객체지향 패러다임이 줄 수 있는 가장 큰 이점은 다형성(polymorphism)을 통한 재사용성(reusability)이다. 이러한 재사용성은 구현측면에서 코드의 재사용, 그래픽 사용자 인터페이스의 재사용, 분산 시스템에서의 인터페이스의 재사용에서는 잘 이루어지고 있으나, 설계단계에서의 재사용성은 아직 부족한 실정이다. 본 연구에서는 이러한 객체지향 설계단계에서 재사용할 수 있는 디자인 패턴(Design Pattern)으로서 분산 객체 환경인 CORBA 시스템 설계 시 적용할 수 있는 새로운 CORBA 디자인패턴을 제안한다. Designing object-oriented software is hard, and designing reusable object-oriented software is even harder. Design should be specific to the problem at hand but also general enough to address future problem and requirement. Expert Designers reuse solutions that have worked for them in the past. This solution is Design Pattern. The propose of this paper is to record experience in designing distributed-object CORBA software as CORBA design pattern.

The flatness is the most important nature for the surface table. For finding such a flatness, the surface is surveyed along a number of straight lines parallel to the edges of table, which form a grid. Next, the variations in height of the grid points are measured relative to a datum point. If the number of such points is increased. It is not necessarily to use many grid points for finding the original flatness ofa measured surface tabel. So it is necessary to find the rational quantity of such grid points. It is found that about 220 points per 1 m? of surface tabel for measurement is the rational quantity with less than about 15% error of the original flatness.

합병증이 동반된 Meckel씨 게실을 가진 환자의 치료에 대한 필요성은 과정이 문제이다. 하지만 우연히 만나는 게실의 처치는 논란 중이다. 부수적인 게실 절제술(incidental diverticulectomy)의 제안자는 증상이 있는 게실의 외과적 처치는 중요한 이환 및 사망률은 지적한다. 이를 반대하는 사람들은 전 생애를 통해 합병증의 위험성이 낮게 나타나므로 필요가 없다고한다. 게실의 예방적 제거는 개복술시 우연히 발견 될 때 시행한다. 이는 남아있는 게실이 나중에 합병증을 일으키는 것보다 술후 합병증의 위험성이 매우 적음을 알 수 있다. 저자들은 합병증이 동반된 Meckel씨 게실 2예를 경험하였기에 문헌 고찰과 더불어 보고하는 바이다. The necessity for therapy with complicated Meckel's diverticular is a matter of course.However, management of the incidentally encountered diverticulum is controversial. Proponents of incidental diverticulectomy point to the significant morbidity and mortality rates of surgical treatment of symptomatic divenicular. Other authors base their opposition to incidental diveniculectomy on the low risk of complications developing during lifetime. Prophyillctic removal of the diveniculum is indicated when it is found incidentally at laparotomy, because there are few postoperative complications and the risk exists that the remaining diverticulum may be the cause of later complication. The 2 cases of complicated Meckel's diverticulum are reported with a brief review of literature.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) that is commonly found on the human perineal skin. Contrary to other CNS, S. lugdunensis is a rare contaminant in cultures and has the potential to cause clinically significant infections, including infective endocarditis. Infective endocarditis due to S. lugdunensis have been known to resemble endocarditis due to S. aureus because of its aggressive clinical course and high mortality. We report a case of infective endocarditis caused by S. lugdunensis in a 21-year-old woman. She was cured of the infection with surgical and antibiotic therapy. S. lugdunensis에 의한 감염성 심내막염은 국내에서보고가 없었던 매우 드물지만 다양한 합병증과 높은 사망률을 보이는 감염증이다. 저자들은 S. lugdunensis가 수술적 치료와 항생제 치료로 완치된 감염성 심내막염 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Recently, there have been much corncerns about the strategies which can reasonably increase farm income at the average farm level. In other words, as a result of third-term Five Year Economic Development Plan there was a remarkable gap between farm household and non-farm household incomes. Therefore, various policy tasks to eliminate this unbalanced income growth are currently being implemented. This study was carried out to identify the situation of livestock farming at general farm level, regarded as one of income generation strategies for the farm sector. Some results of the study can be summarized as follows: First of all, it was found that a group of farms which raise a small size of animals like Korean cattle, hog, and various poultry gave higher resource bases as compared with that of non-livestock farms. Secondly, it was also recognized that both farm and farm household income levels of small-scale livestock farms were higher than those of non-livestock farm group within the same region, specifically as much as approximately ￦200,000. Thirdly, it was known that the average size of animal raising per household in 0.9 head of cattle, 0.8 head of hog, and 34 lyers of poultry, respectively. To the end, according to the farm disposal practices of major by-products, only about 18 percent of total rice straws produced at individual farms was utilized for the animal raising, and about 45 percent of all the brans available at farms for the livestock enterprise. The rest of straw and brans in regarded as selling at farm level. In this respect, it may be recommended either to increase current size of animals or to expand number of livestock farms.
