갯쥐꼬리풀(Spartina alterniflora)은 북미 대서양 연안 뉴펀들랜드, 캐나다 남쪽에서 아르헨티나 북부의 갯벌이 원산이며, 생장이 강한 특성으로 세계의 기수지역과 해안에서 생태공학적 용도로 도입된 바 있다. 그러나 매우 빠르게 갯벌을 피복하여 자생종의 생장을 방해하고, 염습지 종다양성을 감소 시켰고, 결과적으로 과다생육으로 갯벌 무척추동물의 서식지를 잠식해 사라지게 하여 무척추동물을 먹이로 하는 조류 또한 생태계 내에서 감소키는 등 많은 환경문제를 야기 시켰다. 우리나라에서는 2008년 전후에 다도해해상국립공원에 유입된 것으로 판단된다. 현재 다도해해상국립공원 남동리 해안에서 분포하고 있는 갯쥐꼬리풀(Spartina alterniflora)군락은 습지내 총 6개의 염생식물 군락면적(8,487.7㎡) 중 75.34%의 비율(6,394.86㎡)로 분포하고 있다. 또한 2008년에 11.54㎡ 이던 분포 면적이 2015년 현재 약 550배가 늘어난 6,394.22㎡로 조사되었고 생육지 고도 범위인 0.69m~1.1m를 요인 값으로 두고 GIS 분석한 하였다. 그 결과 앞으로 확산 될 예상 면적은 12,584㎡이며 현재보다 약 6,189.14㎡가 늘어날 것으로 예측되며 우리나라에서도 역시 확산이 빠르고 넓게 늘어날 것으로 판단된다. 향후 계속 분포역이 확대 될 것으로 예상하고 관리방안을 위하여 시범 연구를 실시하였다. 갯쥐꼬리풀군락 중 일부를 첫 번째는 뿌리째 뽑아내기와 두 번째 지상부 제거 후 포장덮기 방법 등 국외사례의 문헌을 바탕으로 방재를 실시하였으나 전체 면적을 방재하기에는 많은 인력과 시간 그리고 예산이 소요되므로 다각적인 방안을 강구하여야 한다. Spartina alterniflora is native to the Atlantic coast from Newfoundland, the south of Canada and northern Argentina. There it forms a dominant part of brackish coastal saltmarshes. Due to its strong growth, the Spartina alternifolra was introduced to the rider area and coast as a use for ecological engineering. The Spartina alterniflora community can crowd out native species, reduce the biodiversity of saltmarsh and alter the environment. As a result, the invertebrates living in mud flats disappeared due to the encroaching of Spartina alterniflora, and the birds which eat off invertebrates went along as well. The Spartina alterniflora was first introduced in South Korea in 2008 and is known to have flowed in the Dadohaehaesang National Park. Compared to 2008, in 2015 the distribution area of the Spartina alterniflora has increased 550 times. (11.54㎡ in 2008 to 6,394.22㎡ in 2015). The large increase of Spartina alterniflora calls for urgent management and additionary study on the subject. Thus, this study analyzed the geo-spatial information on the Spartina alterniflora such as its distribution area, the height of habitats and expected expansion area, and can act as the preliminary data for management.

본 연구는 경주지역 1개 고등학교 3학년 여고생을 대상으로 초경 시작 전인 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레 수치와 초경 연령을 파악하여 여성의 초경이 빠를수록 체성장 속도의 변화가 있을 것이라는 가설을 기초로 두 요인간의 관련성을 파악하고자 시행되었다. 경주시 1개 여자고등학교 3학년생 총 317명에 대해 ㅊ경 나이, 초경시 심리 상태, 초경이 시작되었을 때의 상담 여부와 상담하였던 사람, 부모 신장과 초경전후의 식사 규칙성, 다이어트 경험, 수면시간, 스트레스, 음주/흡연 여부, 질병력 등에 대한 설문 조사를 시행하였고, 초등학교 4학년부터 고등학교 2학년까지의 키, 몸무게, 가슴둘레에 대한 정보는 건강기록부에서 확보하였다. 상기 대상자 중 건강기록부가 분실된 39명, 초경나이에 대해 응답하지 않았던 29명 및 결석 등으로 조사를 하지 못하였던 42명을 제외한 조사 대상자는 206명으로 선정하였다. 대상자들의 초경연령 평균값(Mean±SD)은 13.0±1.11이었고, 초등학교 4학년부터 고등학교 2학년까지의 초경 이후 신장 성장률은 감소하였으며, 초경연령이 빠른 군이 초등학교 때는 신장에 있어서 우위를 차지하나 고등학교에 오면서 신장은 비슷한 수준이 되었다. 초경후 1-2년 사이에 체중과 흉위의 증가율은 감소하였고, 초경연령이 빠른 군이 초등학교와 고등학교 사이에 체중과 흉위에서 모두 우위를 차지하였다. 본 연구의 결과는, 흔히 이차 성징의 시작 시점 혹은 사춘기의 시작 시점으로 보고있는 초경 연령이 청소년기의 성장과 밀접한 관련성이 있고, 특히 체중과 흉위의 성장 속도와 밀접한 관련성이 있음을 시사한다. To understand the onset of menarche in relation to changes in physical growth that take place during female adolescence, especially the changes in height and weight velocity. The 207 senior in one women high school of Kyongju were investigated in April 3 to 8, 2001. We collected the information, relation in the age at menarche, height & weight of parents, regularity of eating, and obesity diet, duration of sleeping, sickness & stress near age at menarche, by self-recording. The status of height, weight & chest circumference between the 4th grade of primary school and the junior of high school was collected by individual Health Record. The results were followed; The average age at menarche was 12.95±1.11 years old and the most frequent age of menarche is 13 years. After menarche, the velocity of height, weight and chest circumference were decreased. The most rapid group of menarche hold dominant position in height during elementary school. As time passed, they dont hold dominant position in height. The most rapid group of menarche get an advantage in the weight and the girth of chest after elementary school. The height of subjects is directly proportional to the height of their parents. These results suggest that the starting age at menestuation can be closely associated with physical growth and development.

Multiple myeloma is a disease caused by neoplastic plasma cells that synthesize abnormal amouts of immunoglobulin or immunoglobulin fragments. Light chain myeloma are regarded as a separate category characterized by a more malignant clinical course. Light chain myelomas are said to grow fastest of all and are associated with more osteolytic lesions, more hypercalcemia, and a higher incidence of renal failure and amyloidsis than either the IgG, IgA varienties The authors experienced a case of patients with λ-light chain myeloma. A 43-year-old male patient admitted to our hospital with the chief complaint of both rib and lower back pain. The radiologic findings showed multiple pathologic fracture in ribs. osteolytic lesions in 2nd, 3rd cervical spineimmuture plasma cells. Serum electrophoresis showed normal finding. Urine electrophoresis evealed an M-spike. Urine immunoelectrophoress demonstrated λ-monoclonal protein. With the cycle of melphalan, prednisone and α-interferon chemotherapy improved of pain was observed. So we reported the case with brief review of previous literature.

In rare occasions in which aneurysmal neck clipping is nearly impossible, coating is employed. During the period from 1985 to 1992, 312 patients with aneurysm underwent surgery ; aneurysmal neck clipping were performed in 284 cases while coating only in 28. The reasons that coating was required were ; wide and broad neck in 13, perforators arising from the neck in 4, neck tearing during dissection in 3, very friable neck in 2, severe adhesion with surrounding structures in 3, and small aneurysm without enough room for clipping in 3. In twenty-three cases, cotton wisp and bioglue were used as coating materials. In another five cases, the aneurysmal wall was reinforced using Surgicel or Gelfoam. Patients were followed for 24 months on average of all the patients. Four had last contact Six died(4 due to rebleeding and 2 due to pneumonia). Fourteen were good and 4 were moderately disabled. There were no rebleeding incidences during first three months' follow-up after coating. We thus concluded that coating an aneurysm offers some protection from rebleeding, particularly when the rebleeding risk period is over.

Difficulties arise in prediction of maintenance of the graft volume and viability of graft over time when a bone graft used for facial reconstruction. A bone-to-bone contact between the graft and the recipient bone is imporant for creeping substitution and survial of the recipient bone is important for creeping substitution and of the grafted bone. An adequate blood supply is also essential to ensure the survival of any live cells of the surface of the graft. Our study was designed to determine which one is an important factor viability of the grafted bone in Korean adult dogs : a bone-to-bone contact or overlying soft tissue. Blocks of outer table of the parietal bone were placed at the maxillae subperiostially in 4 different ways : bone-to-bone contact groups(groups Ⅰand Ⅱ)with placing a silicone membrane over the grafted bone and soft tissue contact groups(groups Ⅲand Ⅳ)with placing a silicone sheet between the grafted bone and the recipient. In groups Ⅰand Ⅲ, the cancellous surfaces of the parietal bone was placed on the recipient and the cortical surfaces were placed on the recipient in groups Ⅱ and Ⅳ. Caliper techniques were used to study the rates of volume maintenance of the grafts at 6, 12, and 20 weeks after bone grafting. The volumes of the living bone were quantified microscopically using a modified point-countiong technique. The volume is reduced in a similar rate with time in all groups. At 6 week, living bone cells increased in soft tissue contact groups Ⅲ and Ⅳ however, and increased in bone to bone contact groups Ⅰand Ⅱ at 12 and 20 weeks. there were osteoblastic proliferation and laminated mature bones in group Ⅰand Ⅱ. But osteoclasts and their associated osteolytic changes were still seen near the silicone membrane in group Ⅲ and Ⅳ, which may imply a continuing resorptive process with time. In summary, revascularization from the overlying soft tissue is important for the graft survival in early stage of the bone grafting while bone-to-bone contact may be essential in a later stage.

Background and Objectives: Maternal alcohol abuse is considered to be one of the most prominent cause of neurobiological malformations in the postnatal and adult life of the offspring. In this study, we investigated the effects of maternal alcohol drinking on the postnatal development of NPY-containing neuron, and, the influence of thyroxine treatment on the cerebral cortex and hippocampus of pups of alcohol abused mother. Materials and Method: Time-pregnant rats were divided into three groups. Alcohol-fed group A received 35 calories of liquid alcohol diet daily from gestation day 6; control pair-fed group B was fed a liquid diet in dextrin replaced alcohol isocalorically: alcohol + T4 group C received 35 calories liquid alcohol diet and exogenous thyroxine subcutaneously. Results: Group C showed prominent NPY immunoreactivity in the cerebral cortex compared to group A and B at P7. In group C, NPY-containing neurons were widely distributed in the all layers of cerebral cortex after P14. Besides, numerical decrease of NPY-containing neuron as age increases was not found in group C. However, the decrease of NPY-containing neuron was clearly observed in group A compared to group C after P14. In hippocampus, group Band C were appeared similar patterns after P7. Additionally, in group C, NPY immunoreactivity was prominently appeared in CA2 and CA3 at P14 as compared to group B. Conclusions: The present results showed the increase of intensity and number of NPY-containing neurons in cerebral cortex and hippocampus of pups of exogenous T₄ supplemented alcohol-exposed dams as compared to control pair-fed and alcohol-exposed pups at P7. It presumably suggest that NPY-containing neurons might be regulated by the early postnatal growth stimulatory effect of the exogenously supplemented T₄. Therefore, the increase of NPY synthesis caused by maternal administration of exogenous thyroxine may ameliorate fetal alcohol effect, one of the ill effects as a result of the dysthyroid state following maternal alcohol abuse.

1989년 9월부터 1993년 7월까지 인제대학교 의과대학 상계백병원에서 실시한 위내시경 소견이 조기위암이며 내시경 직시하 생검결과 선암으로 판명되어, 근치적 위절제술을 시행받은 23명의 환자에서 임상적 특징을 알아보고, 문헌고찰과 함께 보고하는 바이다. The incidence and mortality rate of stomach cancer ranks well ahead of all malignancies in Korea. The prognosis is excellent in early gastric cancer of which the overall 5 years survival rate of 85∼95% is comparative with that of advanced gastric cancer of 15∼49%. So early detection with very sensitive mordality of gastroscope and surgery is the only premise to decrease the mortality rate of gastric cancer. This report deals with the clinical aspects of 23 cases of early gastric cancer, which were confirmed with histopathologic examination of resected stomach during the 4 years from September 1989 to July 1993 at Sanggye Paik hospital, Seoul, Korea. Out of 23 cases of early gastric cancer, 14 cases were male, 9 cases were female, and the male to female ratio was 1.6 : 1. The most common type of early gastric cancer was talc type(43.5%), IIc and its combined type comprised most of them(87.0%). The most prevalent sloe of lesion was gastric angle(43.5%) and the most common direction was lesser curvature(73.9%) 19 cases of 23(78.3%) were between 1∼3cm in size, and there was no statistical significance between the size of the lesion and lymph node metastasis. Of the 9 cases with mucosal lesion, there were 2 cases with lymph node metastasis(22.2%), but 7cases(50.0% ) of 14 cases with submucosal lesion presented lymph node metastasis. Diagnostic accuracy of endoscopy on detection of early gastric cancer was 17 cases(73.9%) of total 23 cases in our study. As with other report, histopathulogic examination of resected stomach revealed adenocarcinoma, tubular type as the most common type. Frequent complaint of patients with early gastric cancer was epigastric pain(65.2%), and duration of the symptom was less than 12 months in 17 cases(73.1%) of 23 patients with early gastric cancer.

This study conducted for analyze the process of physiological variation during shooting, and produce the basic data for training prescription to the performance improvement in Air Rifle Shooting, 9 Elite Rifle shooters )College 3, High School 3, Middle School 3) in GangWeon province were tested the physiological parameter which are Electrocardiograph(E.C.G), Heart-rate(H.R), Respiratory pattern, and Trigger time by polygraph system 8 channel from Sept. 1st to Sept. 10th, 1985. Analyzed experimental results are as follows; 1. Firing at T-P wave in E.C.G, 77.68bpm in H.R)16.68% by resulting H.R), the deep size of inspiration-expiration was low, and 8.34 sec of trigger interval were appeared when the shooter acquired high score. 2. The most effective factor among physiological parameters for excellent shooting score is the inspiratory volume with decresc breathing pattern. 3. Shooting performances correlated with stability and static-dynamic balance, but flexibility effected on negative correlation.
