All dwelling complex should be plan with the consideration on the cars. this is because the car is no only a necessary tool for the man's various wants, but also a checking cause for the dwelling complex's comforts. this study focuses on the apartment complex of the dwelling scale taking a large percentage in Kwangju, and the various matters and the remedy about the parking space. the results are following. 1. The parking space is affected by the dwelling bwelling's arrangement, the open space and the incidental facilities. therefore the apartment complex plan of the future must apply the view of mass space. 2. Recently, the environs of the dwelling building are used as a parking space. It affects a bad effect on the complex's comfort. So the laws enacted to establish the underground parking place are required. 3. For the great comforts and closeness, the complex's plan has to consider the closeness of the complex entrance, the dwelling building entrance and the parking space.

We investigated the floral resources of the honeybee (Apis mellifera)bypollenDNA metabarcoding as the first step in honeybee conservation. We attempted to identify as many floral resources and as wide resource availability as possible in areas and compared the richness of floral resources between forests and national parks. We found that both forest and national parks can sufficiently support honeybee floral resources; however, national parks were more stable habitats with more complex vegetation structure than those of forests. Also, honeybee’s preferences for floral resources were determined using niche breadth, niche overlap, and network analysis among the floral resources in forest areas. Quercus and Actinidia were the most frequently detected taxa of pollen resources in both forests and national parks by pollen metabarcoding. Even though we anticipated that more various pollen resource taxa would be found in national parks than forests, no differences in the number pollen resource taxa were detected between them. According to the niche overlap analysis result, the honeybee preferred the pollen resources in both forests and national parks, and the co-occurrence pattern analysis of pollen resource taxa in both forests and national parks showed a simple network. Altogether, our findings suggested that DNA metabarcoding of pollen collected by the honeybee can provide useful information on the flowering plants in a given area. As the use of floral pollen resources varies spatially and temporally, periodic monitoring of pollen resources can identify which pollen is required to maintain the health of honeybee colonies.

복합 적층 탄성지지판의 유한요소해석

박문호,김진규 경북대학교 산업기술연구소 1994 産業技術硏究誌 Vol.22 No.-

Now an equivalent homogeneous, orthotropic model that includes edge effects and an accompanying finite element program are developed using multiscale approach and element condensation algorithm. The model is devloped for 2-dimensional configurations with horizontal layers, and for linear, elastic, small deformation conditions. The equivalent homogeneous theory, in addition to capturing the overall response characteristics of the layered elastomeric bearing, approximately models the important edge effects, which occur at and near boundaries that cut the layers, and the stress concentrations at layer interfaces. The primary dependent variables for the theory have been selected such that the highest derivatives appearing in the strain energy function are first order. Thus the required continuity condition for finite element program is C˚ continuity. Therefore the finite element analysis is simple and computationally efficient. Numerical tests are presented to verify the theory and to illustrate potential applications of the analysis.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

고등학생 경제 이해력 테스트 조사결과

朴文圭 한국경제교육학회 2002 경제교육연구 Vol.9 No.1

조사대상 고교생들의 경제 이해력은 100점 만점에 평균 55.7점인 것으로 조사되어 경제 이해력이 다소 낮은 것으로 나타났다. 실업계 학생들의 평균 점수가 43.9로 일반계 학생들(평균 57.4점)에 비래 크게 떨어지는 것으로 나타나, 상대적으로 사회에 일찍 진출하는 실업계 고교생들의 경제 이해력 수준 향상이 시급한 것으로 사료된다. 고둥학교 2, 3학년생들을 대상으로 경제과목 수강여부에 따른 경제 이해력 수준을 비교해본 결과, 수강한 학생(평균 57.8점)과 수강하지 않은 학생(평균 56.6점)간의 차이가 유의하게 나타나지 않았다. 경제 이해력을 분야별로 비교해 볼 때, 기초적 경제개념에 대한 이해력은 60.0점으로 가장 높게 나타난 반면, 국제경제관련 개념은 46.8점으로 가장 낮았으며, 다른 분야에 비해 점수차도 크게 벌어져 국제경제관련 이해력이 가장 문제시되고 있다는 것을 보여주고 있다. 인식수준별 이해수준 비교에서 응용력은 52.2점으로, 경제이론에 대한 이해력(60.2점)과 경제지식(59.3점)에 비해 상당히 떨어지는 것으로 나타났다. 이번 조사를 통해 볼 때 우리 경제가 시장경제 원리를 토대로 지속적으로 발전하기 위해서는 대국민 경제교육의 최후 공급자라 할 수 있는 고등학교 경재교육을 강화할 수 있는 다각적인 노력이 필요하고, 우리나라도 선진국처럼 정부가 정제교육에 적극적으로 대처할 것이 요구되고 있다. The result of the Economic Literacy Test taken by high school students in Korea yielded 55.7 point average on a 100-point scale. For students in vocational programs the average was even lower with 43.9 points compared to students that are in regular high school academic program (57.4) magnifying the urgency for improvement in the economic literacy of the students in high school vocational programs who will be entering the business market sooner than those students in the regular high school academic program. For high school student in the second and third grades, 57.8 point average was recorded for those who have taken an economics course in their high school curriculum while those students who never took an economics course marked 56.6 point average, not showing a remarkable difference. When comparing various categories of economic literacy, the highest score of 60.0 points was recorded in understanding basic economic concept while understanding international economy had the lowest score with 46.8 points and the gap between other categories with international economy remained wide proving this category as the least understood among students. Under cognitive categories, students' knowledgein economic application recorded 52.2 points while economic theory and understanding economic knowledge both recorded 60.2 and 59.3 points, respectively showing a wide gap between the economic application and other two categories. The result from this test clearly indicates that in order for our economy to continually grow followingthe principles of the market economy, the study of economics in high school education must be strengthened in multilateral scope and a full-fledge effort by the government in educating the students is required.

We analyzed 23 patients with bladder rupture managed at Chosun Univercity Hospital during a 8 year period from January 1978 to December 1985. The results are as follows; 1. Among the 182 patients with genitourinary injury, the patient with bladder rupture are 23 cases(12.6%). 2. Age distribution of bladder rupture shows the most prevalent incidence in the age group from second to fourth decade, giving a rate of 52.2% of total 23 cases. 3. Traffic accident is the most frequent cause of bladder rupture, "which is occurred in 12 cases" (52.2%)of 23 cases. 4. The most frequent associated injury is the fracture of pelvic bone and the next are intestinal injury, urethral rupture and the fracture of upper and lower extremity. 5. The occurence of the intraperitoneal rupture is 6. 7times more than that of extraperitoneal rupture. 6. Transverse tearing is the most common tearing sliaps of bladder wall, which consist of 14 cases in 20 cases explored and the most common tearing diameters are between 5 to 10㎝. 7. In almost all cases, immediate primary anastomosis of bladder wall and indwelling urethal catheter, with or without auprapubic cystostomy are performed, except 3 cases who are managed with indwelling urethral catheter.

A variety of swallowed foreign bodies are seen in gastrointestinal tract. However 80-90% of objects usually pass spontaneously through the alimentary tract and out in the feces and 10-20% removed without complication endoscopically. Therefore about less than 1% of foreign bodies ingested only require surgery due to complications, such as perforation, obstruction. Perforation of the gastrointestinal tract is a well-recognized complication of the foreign body ingestion. The most common site is ileum. Unfortunately, the diagnosis of small-bowel perforation by foreign bodies is rarely made preoperatively because the clinical symptoms are usually nonspecific or mimic other surgical conditions, such as appendicitis, diverticulitis, and perforated peptic ulcer etc. We report here a rare case of the small bowel perforation with mass-like intraabdominal abscess by fishbone ingestion in 59-year-old man who presented with a non-tender palpable mass in the left paramedian area and underwent abdominal computer tomography initially reported as showing intraabdominal mass.
