The purpose of this study is to investigate and reveal the effects that the complex exercise training consisting of aerobic exercise and strength training(sit up, push up) that everyone can easily practice regardless of a time and a place in order to manage practically the physical strength of the aged affects the difference on their body composition and the change of physical fitness level. Looking into the change of body composition of an experimental group, the weight of 2.5kg was reduced after applying complex training for 12 weeks and the body fat mass of 2.65kg was reduced. Also, the abdominal fat of 0.13% was decreased and the muscle mass of 1.56kg was increased. For the change factors of physical fitness, cardiovascular endurance, muscular strength, muscular endurance, balance and flexibility excluding agility showed significant improvement after applying complex exercise training. The improvement of health fitness of the aged under this study was significantly effective to improve specified body functions which had been lowered by aging and insufficient physical activities. So, it is regarded that their health fitness is the important factor to improve the activity competence required for daily life and to lead healthy living by the improved activity competence. Henceforth, it needs to study more the complex composition of several sports, exercise intensity and the frequency based on the previous researches and studies. In addition, it needs to develop the complex exercise training in accordance with various characteristics such as a sex of the aged, an age, a physical fitness level, environment, a disease and the program in consideration of the efficacy and safety during training.

This study was performed to identify the differentially methylated region (DMR) and to examine the mRNA expression of the imprinted H19 gene in day 35 of SCNT pig fetuses. The fetus and placenta at day 35 of gestation fetuses after natural mating (Control) or of cloned pig by somatic cell nuclear transfer (SCNT) were isolated from a uterus. To investigate the mRNA expression and methylation patterns of H19 gene, tissues from fetal liver and placenta including endometrial and extraembryonic tissues were collected. The mRNA expression was evaluated by real-time PCR and methylation pattern was analyzed by bisulfite sequencing method. Bisulfite analyses demonstrated that the differentially methylated region (DMR) was located between -1694 bp to -1338 bp upstream from translation start site of the H19 gene. H19 DMR (-1694 bp to -1338 bp) exhibits a normal mono allelic methylation pattern, and heavily methylated in sperm, but not in oocyte. In contrast to these finding, the analysis of the endometrium and/or extraembryonic tissues from SCNT embryos revealed a complex methylation pattern. The DNA methylation status of DMR Region In porcine H19 gene upstream was hypo methylated in SCNT tissues but hypermethylated in control tissues. Furthermore, the mRNA expression of H19 gene in liver, endometrium, and extraembryonic tissues was significantly higher in SCNT than those of control (p<0.05). These results suggest that the aberrant mRNA expression and the abnormal methylation pattern of imprinted H19 gene might be closely related to the inadequate fetal development of a cloned fetus, contributing to the low efficiency of genomic reprogramming.

식물과 그 식물의 근권미생물과의 협력관계는 이미 오래전부터 관심을 받아왔고 지구 기후변화에 따라 식물과 그 근권미생물의 생태 및 지구환경에 대한 적응성은 막대한 지장을 받을 것으로 생각되어 왔다. 따라서 지구온난화에 따라 식물뿌리에 서식하는 근권미생물인 토양미 생물의 우점종이 어떻게 변화하는지에 대해 규명하고자 본 실험을 실시하였다. 우선 한국 식물생태계의 대표종인 소나무 (A), 잣나무 (B), 상수리나무 (C), 오리나무 (D) 를 선발하여 각각 실

It is a true fact that the ancient Buddhist temples of Korea were great, important historical influence revealing the transition and developing stages of all the BUddhist temples in Eastern Asia including China and Japan. Before Mahayana arose within India, the monastery and pagoda were united during the conflict and development of the original Buddhism and pagoda faith. With the arising of Mahayana and the introduction of Buddhist statues, the Buddhist temple and pagoda were in conflict and resulted in separation. With the creation and development of the Mahayana Bodhisattva concept, Hinayana and Mahayana started to show doctrine differences and expressed each others' characteristics relevant to the structure of the temple. As a result, the Buddhist Temple having 1 pagoda spread in China together with Hinayana and Mahayana. The Buddhist temple of Hinayana had its temple and pagoda separated and the Buddhist temple that has a pagoda in front was divided into a form of 1 pagoda and 1 main temple. The temple and pagoda for Mahayana in the form of 1 pagoda and 2 temple, where the main statue of the Buddha may be worshipped from both the left and right hand sides, were separated in the form of 1 pagoda and 3 temples to have its original form again. Mahayana was first introduced into Goguryeo through the routes in the northern region and developed from having 1 pagoda and 2 temples, to having 1 pagoda and 3 temples. China was influenced by the southern regions, which is why Abhidharma was introduced into Baekje. Later on, the importance of Bodhisattva increased and the transition speed of the Buddhist temple having 1 pagoda and 3 temples accelerated, as Buddhism became more popular and as Mahayana flourished. The statue of the Buddha on both sides of the pagoda shall gradually move next to the central temple , and the temple shall form large crowds to not only form a tacit boundary with the pagoda but the expansion of Bodhisattva shall also have a wall or a corridor constructed in between the central, left and right hand side temples to form separate areas, and shall have a pagoda built in front of the temples that worship from both sides. In conclusion, independence shall exist among each Bodhisattva within the Buddhist temple, and the status of the pagoda shall fall and appear as the pagoda on both sides in front of the main Buddha statue.

신평천 인공습지 조성 후 3년간의 식생 및 생활형 변화 연구를 위하여 2005년 6월부터 2007년 9월까지 현지조사를 실시하였다. 2004년에 조성된 신평천 인공습지의 식재종은 14과 18속 15종 5변종으로 총 20종류가 식재되었다. 식재종의 생활형 구성비는 전체의 65%인 대부분을 다년생이 차지하고 있으며 목본류는 물푸레나무와 왕버들, 동백나무, 남천 4종류가 식재되었다. 3년간의 조사 기간 동안 생활형의 변화는 수생식물(HH)이 가장 많은 비율을 차지하며 증가하였고 소형지상식물(M), 대형지상식물(MM), 지표식물(Ch), 미소지상식물(N), 다년생식물(H)과 지표식물(Ch) 등도 증가하였다. 식생면적 변화는 애기부들, 달뿌리풀, 갈대 등은 군락면적이 증가하였으나, 다른 식재종의 면적은 급격히 감소하였다. 생활형 면적변화를 살펴보면 수생식물(HH), 1년생 수습식물(Th(w))은 점차 증가하였으며 소형지상식물(M), 지중식물(G), 미소지상식물(N) 등은 감소를 보였다. 결론적으로 식재 식물의 선정은 인공습지의 미래를 결정하는 중요한 요인이며 습지 조성 후 정착된 식물상의 파악 및 이들 식물들의 생활형을 분석하여 인공습지 초기정착에 유리한 종, 천이가 진행되면서 습지의 안정화 및 다양성을 유도하는 종을 선정하는 것은 매우 중요하다.

본 연구는 기후변화에 따른 한반도 난온대 상록활엽수의 분포변화와 CT분석을 이용하여 난온대 상록활엽수의 분포를 규정하는 기후요인과 분포적지를 밝히는 것을 목적으로 실시하였다. CT분석을 통해 구축된 한반도 난온대 상록활엽수 분포 모델(EG-model)에서 TMC(최한월최저기온)가 분포를 규정하는 주요 요인으로 작용하였으며, TMC(최한월최저기온)의 -5.95℃이상을 난온대 상록활엽수의 분포적지로 하고 있다. 이러한 TMC값을 CMT(최한월평균기온)으로 환산한 값인 -1.7℃는 동아시아 지역 상록활엽수림의 내성한계 온도인 최한월평균기온 -1℃다 약간 낮은 것으로 분석되었다. 한반도의 난온대 상록활엽수는 최한월최저기온(TMC) -5.95℃이상의 따듯한 지역에서는 하계강수량 (PRS)이 826.5mm이상인 지역에서, 최한월최저기온(TMC) -5.95℃미만의 추운 지역에서는 하계강수량이 1219mm이상인 기후조건에서 높은 분포확률을 나타내었다. 이러한 분포경향은 일본의 난온대 상록활엽수의 분포경향과 비슷하였다. 또한, 난온대 상록활엽수는 한반도의 기온상승에 따라 고위도 및 남부내륙으로 분포를 확대하고 있으며 난온대 상록활엽수의 북방한계선 변화를 시사하고 있다.

The purpose of this study was to identify the effects of manual facilitation and a stick on lumbar and hip joint flexion angles in subject with lumbar flexion syndrome during forward bending from a sitting position. Fifteen subjects with lumbar flexion syndrome were recruited for this study. As a pretest, all subjects performed three repetitions of bending the trunk forward until the tips of their fingers touched the target bar. After this pretest, the subjects practiced the forward bending of the trunk 10 times, using either manual facilitation or a stick. Then, as a posttest, all subjects repeated the pretest procedure. The flexion angles of lumbar spine and hip joint during forward bending in a sitting position were measured using a three-dimensional motion analysis system. A paired t-test was used to determine the statistical differences between pre-test and post-test flexion angles and pre- and post-test flexion angle differences between forward bending with manual facilitation and forward bending with a stick. The level of statistical significance was set at p=.05. The results of the study showed that the angle of the lumbar flexion decreased significantly and the bilateral hip flexion angle increased significantly when performing forward bending with stick and manual facilitation. Furthermore, the angle of lumbar flexion decreased significantly and the angle of bilateral hip flexion increased significantly in forward bending with a stick compared to forward bending with manual facilitation. The findings of this study indicate that both forward bending with manual facilitation and sticks could be used to prevent excessive lumbar flexion and increase hip flexion, and that forward bending with a stick is more effective than forward bending with manual facilitation for inducing lumbar spine and hip joint angle changes.

본 연구는 국내 초기 생태하천 조성사업인 수원천을 대상으로 조성 후 10년간의 식생변화를 분석하고 생태하천의 식생관리를 위한 기초자료를 제공하고자 하였다. 연구구간은 1차 복원사업 구간인 경기교~영연교 구간을 대상으로 하였으며 지형구조에 따라 3개 조사구를 설정하고 횡단면 지형구조, 식생분포현황과 초본식물군집구조를 조사하였다. 하천 횡단면 지형구조 분석결과 하천 전체 폭 26.5~28.0m, 저수로 10~20m이었다. 친수공간 조성지역은 넓은 둔치를 확보하고 있었고 보 상부 저수지역은 물 흐름이 완만하고 수심이 비교적 깊은 상태였으며 보 하부 여울지역은 저수로 폭이 넓고 여울을 형성하고 있었다. 식생구조 분석결과 현재 식재종은 9종이었고 조성당시 식재한 종 중 남아있는 종은 버드나무, 갈대, 잔디, 토끼풀 등 6종이었다. 둔치지역은 조성 당시 파종한 종 중 잔디와 토끼풀 2종만이 남아있었고 금번 조사 시 관찰된 신규 식재종은 큰김의털과 오리새 2종이었다. 식재종 이외에는 자연발생종으로 강아지풀과 쑥 등 건조지성 초본이 세력을 형성하고, 귀화종이 15종으로 다양하게 출현하였다. 호안지역은 조성 당시 자연석 쌓기 공법을 적용하고 버드나무, 돌단풍과 바위취 등을 식재하였으나 현재는 식재종이 모두 사라진 상태로 쇠뜨기와 환삼덩굴 등에 의해 피복되어 있었다. 이는 생태하천 복원 당시 유지관리상의 이유로 콘크리트 기초 위에 자연석을 부착하여 식물생육 기반이 확보되지 않았기 때문으로 판단되었다. 저수로는 친수공간 조성지역에 조성 당시 부들, 창포 및 갈대 등 습지성 식물을 식재하였으나 현재 버드나무, 갈대와 줄만이 남아 있었고 보 상부 저수지역과 보하부 여울지역에는 갈대와 줄이 세력을 유지하고 있었다. 자연발생종으로는 고마리가 주로 우점하였고 보 하부 여울지역에서 환삼덩굴이 일부 세력을 형성하고 있었다. 수원천의 식생관리는 친수공간 조성지역은 이용자를 고려한 식생관리 측면에서 양호한 하천식생경관의 연출이 필요하여 이를 위해 물억새를 군락으로 식재하는 것이 바람직할 것으로 판단되었다. 보 상부 저수지역은 줄, 부들과 갈대 등을 수심에 맞게 보완 식재가 필요하였다. 보 하부 여울지역은 갈대, 고마리 등 습윤지성 자생종이 안정적으로 세력을 형성할 수 있도록 환삼덩굴의 지속적 관리가 필요하였다.

The standard does much to improve merchantable quality, distribution efficiency and fair dealings by shipping of the standard agricultural products. Mushrooms notified as the standard are five items; Pleurotus ostreatus, Pleurotus eryngii, Flammulina velutipes, Agaricus bisporus and Ganoderma lucidum. But many farmers are suffering from a strict standards. So these standard is required modification to fit farmhouse situations. This study was carried out to investigate mushroom quality of farm shipping and quality change during preservation at various treatment. Flammulina velutipes and Agaricus bisporus preserved at different temperature( 4℃, 10℃, 20℃) to investigate quality changes. Pileus diameters of Flammulina velutipes was 67% of first grade and 33% of second grade at the early stage. After two weeks, pileus diameters was not signigicant changes; 50% of first grade, 50% of second grade at 4℃ and 50% of second grade, 50% of third grade at 10℃. Although there were no significant changes of diameter at 20℃, most of the fruit bodies were decayed. In case of Agaricus bisporus, pileus diameter was 15% of first grade, 81% of second grade and 4% of third grade at the early stage. The more storage period longed, the more the color of the fruit body was browned. But pileus diameters was not signigicant changes. Hardness and chromaticity of these mushroom was declined as time passed. Now we are carrying out more research on some mushroom’s standards for improve consumer confidence.

We investigated 18 amino acid contents in the fruiting bodies of Agaricus strains to understand their variation in different growth temperature. Although total content of amino acid was more or less different depending on the isolates, it increased until the temperature was 22℃ and decreased above 22℃. Commercial strains of A. bisporus, such as Yangsongi-505, Yangsongi-705 and commercial strain A collected in the market exhibited these general trend in total amino acid content. However, another commercial strain B did not follow these trend. A strain of A. bitorquis did not produce mushrooms at 10 and 13℃, but mushrooms harvested in the other treated temperatures exhibited with the similar patten. Generally, the most amino acid contained in Agaricus spp. was cysteine and followed by phenylalanine, glutamic acid, lysine, proline and histidine. We detected two trends for the contents of each amino acid in the fruiting bodies of Agaricus spp. grown at the different growing temperature. Some amino acid contents were largely correlated with the growth temperature, but the others showed the trend of increase until 22℃ and decrease above 22℃.

To understand the saccharide contents and quantity of winter mushroom (Flammulina velutipes) according to its growth temperature, we measured the saccharide contents at different growth temperature. In our results, the saccharide of its fruiting body turned out to be mainly composed of xylose, trehalose and mannitol in all treatments. In the other hand, Ribose, myo-inositol and sucrose were detected in some treatments. The quantity of trehalose decreased as the growth temperature increased with a variation of its quantity depending on the isolates used in the experiments. In the case of xylose and mannitol, detected in all treatments, the pattern of their quantities was not possible to be profiled and the pattern might be largely depending on the isolates. However, the quantities of xylose and mannitol were largely in a direct proportion and the fluctuation of their quantities was congruent with the exception of ASI 4103, ASI 4166 and ASI 4065. The xylose quantity of ASI 4103 and ASI 4166 increased until the temperature was up to 10℃ and decreased when the temperature was above 10℃. That of ASI 4065 decreased as the temperature rose and increased when above 13℃. The mannitol quantity of ASI　4065 and ASI 4166 decreased until the temperature was up to 10℃ and increased when the temperature was above 10℃. That of ASI 4103 increased as the temperature rose and decreased when above 13℃.

We investigated 18 amino acid contents in the fruiting bodies of Agaricus strains to understand their variation in the harvesting periods. Total content of amino acid was different depending on the isolates. In the case of A. bitorquis and A. brunnescens, the total amino acid content increased and correlated with the harvesting periods. For commercial strains of A. bisporus, such as Yangsongi-505, Yangsongi-705 and commercial strain A collected in the market, it increased until the second harvesting period, but decreased in the third harvesting period indicating that these three isolates exhibit the exceptions for the general trend. Among isolates we used in our experiments, the isolate of A. brunnescens contained the highest and two isolates of A. bisporus were the lowest in total amino acids. We found two trends for the contents of each amino acid in the fruiting bodies of Agaricus spp.. One is the same with the trend of the total amino acid content and the amino acid content were largely correlated with the harvesting period. The other is the trend of increase of amino acid until the second harvesting period and decrease of amino acid in the third harvesting period, which was also shown in the total amino acid content of A. bisporus. Generally, the most amino acid contained in Agaricus was cysteine and followed by phenylalanine, glutamic acid, lysine, proline and histidine.

This study aims to know the trace of Korean musical, consider musical depending on its type, arrange characteristic of musical costume and find out the developmental direction of Korean musical costume with potentials as a culture industry. For study method, the data were collected from thesis, academic journal, book and internet web-site concerning musical costume, literatures were considered and performance costume photos, which were captured via musical performance site, were analyzed. The history of Korean modern-day musical is regarded as starting with 〈Saljjagi Opseoye〉(1966) in the full scale. Although foreign musical was imitated in 1970s～1980s, it may be called the growth period of Korean musical because the period showed the commercial possibility. Since 1990s, large-scaled musical securing good work and popularity was popular. In 2000s, musical industry was abundant quantitatively and qualitatively as investment or popularity was significantly expanded. The type of Korean musical are divided to opera musical of European, Broadway musical of American and creative musical of Korean. The costumes used in opera musical of European and Broadway musical of American are borrowed from original works through license or were manufactured in Korea by referring to the costumes of original works and using similar materials or fabrics. The costumes used in creative musical of Korea are designed by either domestic or foreign designers and produced in Korea.

본 연구의 목적은 고등학교 지구과학 I의 단열변화 주제에 관한 교과서별 내용을 분석하여 향후 교과서 집필 방향에 시사점을 제공하기 위한 것이다. 연구를 위하여 8종의 고등학교 검인정 과학 교과서 중, 일선 학교에서 많이 사용하고 있는 6종의 교과서를 분석 대상으로 선정하였다. 교과서 분석에는 전주시 소재의 교원 양성 대학교에 재학 중인 예비교사 35명이 참여하였다. 먼저 연구자가 사전에 6종의 분석대상 교과서를 살핀 후, 분석관점을 단열변화에 대한 개념 정의, 단열변화에 대한 삽화, 단열변화에 대한 실험의 세 부분으로 범주화하였다. 이를 바탕으로 6종의 교과서를 분석한 후 각 범주별로 가장 우수한 교과서를 선정하였다. 연구 결과 단열변화에 대한 개념정의는 교과서 A, 단열변화에 대한 삽화는 교과서 C, 단열변화에 대한 실험은 교과서 B가 우수한 것으로 선정되었으며, 6종의 교과서 모두 불완전한 부분이 있음이 확인되었다. 이러한 교과서의 부정확성, 부적절성은 학생들이 단열변화를 이해하는 데 어려움을 초래할 수 있으며, 더 나아가 오개념을 형성하도록 하는 문제점을 가져올 수 있다. 따라서 단열변화에 대한 보다 체계적이고 정확하며, 완전한 내용이 담겨지도록 교과서의 내용을 재구성할 필요성이 있다.
