A survey was performed to 174 male young men who were living alone(40 persons) and shared living with friends(4143 persons) in Chungnam province. Their average age was 22.6 years old, height 171.8 ㎝, and weight 65.6 ㎏. Their daily calcium intake level was averaged 271.9±169.1 ㎎, which was 38.8 %RDA. Comparing calcium intake of each mealtime, breakfast, lunch, dinner, and snacks were composed of 18.6%, 30.0%, 34.0% and 17.4%, respectively. Their daily iron intake level was averaged 8.9±10.8 ㎎, which was 74.3 %RDA. Comparing iron intake of each mealtime, breakfast, lunch, dinner, and snacks were composed of 15.4%, 33.6%, 36.3% and 14.7%, respectively. These results suggested that deficiency of the two minerals in young male adults were severe and the nutrient qualities were also poor, no matter of their living alone or with accompanies. The deficiency was more profound in calcium than iron. And we observed iron nutriture differed significantly according to their living status, such as iron intake and its %RDA were significantly worse in single living subjects than the others. However calcium did not show significant difference. We concluded that shared living environment in young male adults could possibly improve their dietary mineral intake levels.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

The regeneration process and the composition of species of climax Platycarya strovilacea S. et Z. forest was studied in Mujang-Ri, Jigok-Myon, Sosan, Chungchungnam-Do Province. Total number of vascular plant species of this community was recorded 125. This results seem to be related to various soil and light conditions in this community. The dominant trees of the stands came up beyond 12m in height. The upper tree layer is highly dominated by Platycarya strovilacea, which have more than two stems, is over 15cm in DBH class and is like stumps. They were distributed horizontally in random. Trees of the middle and lower layer were few in number and small in basal area. It tended to be distributed contagiously, in the age distribution of trees, some of the even-aged cluster which were constituted of several trees, were found in plot. The growth rates of the stem diameter for the first 20 years of the trees in upper layer were higher than those of the same species in the middle layer. These results show that the seedings which were established in dense grows with the decreasing density after the forest canopy had been broken out , and distribution pattern became in random, would constitute the canopy developing the community level.

Patients with chronic renal failure (CRF) are known to be more susceptible to tuberculosis infection due to impairment of the host defense mechanism. Although extrapulmonary tuberculosis is more prevalent in those subjects and it may induce dismal outcome, its diagnosis has been challenging since there is no specific symptoms of the disease and the clinical course is usually atypical. Herein, We report a case of disseminated tuberculosis diagnosed by ultrasound-guided liver biopsy in a 31-year-old CRF patient presenting sustained fever despite broad-spectrum antimicrobial therapy and progressive cholestatic jaundice.

Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

Two farmed young ostrich chicks were applied to pathology laboratory at Chungnam National University. Grossly, one ostrich showed rotated tibiotarsus, the other showed rolled toes. Case 1 ostrich was hypertrophy of fibualis longus and tibial cranialis tendon and gastrocnemius tendon in crus, inflammation of flexor digitorum longus. In histopathological views, myocytes of fiburalis longus were showed hypertrophy and hyperplasia. It is not found any specific feature in X-ray of the case 2 ostrich. Limb deformities were detected frequently in farmed ostrich chicks in 2- to 3 weeks old. Limb deformities were an important cause of mortality in farmed ostrich chicks during the first 10weeks after hatch. Cause of limb deformities were considered a nutrition problem.

이 연구는 도움닫기 마지막 세 스트라이드 및 발구름 동작에서 일어나는 동작 변화를 세 개의 운동면에서 분석하고 발구름 구간에서의 에너지 흐름의 특성을 분석하는 것이다. 이 연구는 2011년 대구세계육상선수권대회에서 남자 멀리뛰기 결승에 진출한 선수들 중 1위에서 8위에 입상한 선수들을 대상으로 5대의 Sony 비디오 카메라를 사용하여 60Hz로 선수들의 운동장면을 촬영하였으며 Kwon3d 프로그램을 이용하여 운동학적 자료를 산출하였다. 또한 에너지 흐름의 특성을 분석하기 위하여 에너지 변환지수와 에너지 전환효율을 계산하였다. 분석 결과 다음과 같은 결론을 얻었다. 도움닫기 마지막 세 스트라이드의 보폭 변화는 전형적인 멀리뛰기 보폭 변화인 보통-길고-짧게 하는 보폭 패턴을 보였으며, 스트라이드 각은 페널티메이트에서 모든 선수들의 스트라이드 각이 크게 나타났다. 수평면에 투영한 도약각도는 이륙순간 좌우속도에 따라 구름판 이륙시점에서 우측 혹은 좌측으로 도약각이 결정되는 것으로 나타났다. 전후면에서 접지순간 다리의 각도가 작을 경우에는 구름판에서 수평속도의 제동이 되는 것으로 나타났다. 이륙순간 다리의 각도가 작게 되면 도약각도는 클 수 있으나 구름판에서 발구름 동작으로 인한 수평속도의 추진력이 떨어지는 것으로 나타났다. 좌우면에서 이륙순간 다리의 각도는 접지에서 이륙순간으로 진행되면서 발구름 다리의 각도가 서로 교차되는 것으로 나타났다. 에너지 변환지수는 경기력이 우수한 선수일수록 높게 나타났으나 Watt 선수처럼 도약각이나 구름판 이륙순간 수평속도의 감속이 크면 작게 나타났다. 에너지 전환효율은 선수들간에 큰 차이를 보이지 않았지만 구름판 이륙순간에서 수평속도의 감속이 크고 수직속도가 크게 증가되면 높게 나타났다. The purpose of this study is to reseach the kinematic variables of the last three strides on the cardinal planes and the energetic processes of take-off performance. The subject of this research were the athletes whos ranked within top eighth of the long jump competition at the 2011 Teagu world championship. Each long jump was recorded using a video camera operating at 60Hz and Kwon3D program was used to analyse the video images of the jumps and the results were as follow: 1. The stride patterns of the subjects utilized the long penultimate-short last stride strategy except Manyongga. All subject of 2nd stride angles showed higher angels. 2. The take-off angle in the horizontal plane was determined with medio-lateral velocity. If the angel of leg placement in the sagittalple was smaller the horizontal velocity decreased a lot. The angle of leg placement in the frontal plane was twiseted at the take-off phase. 3. The transformation index values were higher with the whos performed superior but lower with subject like Watt whos performed on the higher take-off angle and the higher decreased horizontal velocity at the take-off board. 4. The conversion efficiencies were not showed any differences among the subjects but were showed higher with the higher decreased horizontal velocity and increased vertical at the take-off board.

This purposes of this study were to assess the state of current administration and program contents in early childhood institutes. Using APECP(Assessnt Profile for Early Childhood Programs), assesment data were gathered from 27 apprentices in child care centers and 6 apprentices in Kindergarten in Cheongju. Descriptive statistics and Mann-Whitney test were used to analyze data. The result were as follows : (1) The distribution of percentile rate in administration was from 55% to 78%, and the area of Program Development scored the lowest. The assessments for Kindergarten were higher than those of child care center in the areas of Physical Facility, Food Service, and Program Management. (2) As for the program contents, percentile rate was from 62% to 80%, and generally the assessments for Kindergarten were higher than those of child care center. It appears that the certification and assessment system for ealry childhood institutions should be supervised more strongly in order to improve the qulaity of those institutions.
