Backgrounds and Objectives: A fracture means a loss of continuity in the substance of bone. Bone differs from other musculoskeletal tissue due to its ability to repair and heal itself without leaving a scar. The cutter head has multinucleated osteoclast cells to resorb the dead bone. The tail, with its conical surface, is lined with osteoblast cells laying down new bone. The conjugation of fracture is a unique biological process regulated by a complex array of signaling molecules and proinflammatory cytokines. Pyritum, one of the important prescriptions in the oriental medicine, has been used for conjugation fracture. The purpose of this study is to evaluate the effects of administration of Pyritum on activation of osteoblast cells in human body & on tibia bone fracture in mice. Materials and Methods : Four weeks aged 30 female DBA mice were used for this study. They were divided three groups, normal group, control group(fracture elicitate mice: FE group) and experimental group(Pyritum administered mice group after fracture elicitation : PA group). Left tibia bones of mice in FE and PA groups were fractured by bone cutters. MG-63 cells in human body th Pyritum in the ratio of 1 mg/m${\ell}$, and the cells were further incubated for 24 hours. Activation of osteoblast was identified using osteopontin, FGF in vitro test. In vivo test, regeneration of fractured tibia through the morphological changes was observed, and also activation of inflammation through NF-${\kappa}$B p65, iNOS, COX-2, osteoblast through osteopontin, FGF and osteoblast's proliferation in each group was measured. Results and Conclusions : 1. In vitro test for activation of osteoblast cells in human body by Pyritum, osteopontin and FGF production were remarkably increased in Pyritum treated MG-63 cells. 2. In regeneration of fractured tibia by Pyritum, fractured area in external tibia morphology was decreased more in the PA group than that of the FE group. Osteogenesis in fractured area was increased more in the PA group than that of the FE group. Also, endochodrial ossification in central area of fracture and osteoid in lateral area of fracture were increased more in the PA group than those of the FE group. 3. In activation of inflammation by Pyritum administered, activation of NF-${\kappa}$B p65, increase of iNOS and COX-2 production were higher in the PA and the FE groups than those of the control group. Especially, the PA group showed higher activation and increase than those of the FE group. 4. In activation of osteoblast by Pyritum, increase of osteopontin, FGF and osteoblast's proliferation were higher in the PA and the FE groups than those of the control group. Especially, the PA group showed higher increase and proliferation than those of the FE group.

Objective : This study was tried to investigate the specific relationships among cognitve function, neurbehavioral symptoms, and daily living functions, as well as provide the guidline of more proper clinical approches for patients with subcortical cerebrovascular disease. Objects and Methods Subjects were 85 patients whose diagnosis was confirmed by brain CT or MRI and controls were 195 normal persons matched by educational level with the subjects. The cognitive functions were evaluated by BNA(Benton neuropsychiatric assessment), subjective neurobehavioral symptoms by SCL-90-R(Sympton Check List-90-Revised), objective neurobehavioral symptoms by NRS(Neurobehavioral Rating Scale), and daily living function symptoms by NRS(Neurobehavioral Rating Scale), and daily living function by GERRI(Geriatric Evaluation by Relative's Rating Instrument) and IADL(Instrumental Activities of Daily Living Scale). Results: 1) Subjects showed significantly lower cognitive functions than controls in all tests of BNA except Lt-Rt Orientation Test(p=0.09) and facial Recognition Test(p=0.186). 2) In subjective neurobehavioral symptoms, subjects showed significantly lower scores in all symptoms except anxiety(p=0.059), hostility(p=0.159), and phobic anxiety(p=0.849). But in objects neurobehavioral symptoms, subjects showed significantly higher in scores in psychoticism (p=0.000) and neuroticism(p=0.025) of NRS. 3) The score of social functioning of GERRI(p=0.000) and that of IADL(p=0.000) were significantly higher in subjects than in controls. 4) for correlation between cognitive and daily living functions, there were significant correlations between the scores of all items on BNA and the score of cognitive or social function of GERRI and the socre of MDL in corntrols, whereas in subjects, there were significant correlations only between the scores of BNA and the score of IADL. 5) for correlation between neuroehavioral symptoms and daily living functions, there were significant correlatons between the socre of subjective neurobehavioral symptoms and the scores of all subscales of GERRI and the score of MDL in controls. On the contrary, in subjects, there were significant correlations between the score of social function of GERRI and the score of objective neurobehavioral symptoms such as psychoticism, agitiation-hostility, and decrease d motivation-emotional withdrawl. Conclusion : Above results suggest that disturbances in specific function of brain may play a role as a predictor of impairments with specific daily living functions and also suggest that specific correlations among various functions may be useful as clinical parameters for setting of the treatment goal and for assessing the ongoing process in the treatment and rehavilitation of the patients with subcortical cerebrovascular disease.

The purpose of the study was to evaluate the educational content which had been given by midwifery training program. It was hoped that this result would help. It was sponsored by com-munity health worker plan effective health education. College of Nursing Ewha Womans University and The Korean Nurses Academic Society during the November 19 thru 24, 1979. It was carried out on July through on September 1980, and involved 22 community health workers. The results were as follows: 1. Most of the community health workers came from Seoul ＆ Pusan areas and have been working at the hospitals. There were 31.82% of Head Nurses, 27.2% of Staff Nurses, 22.73% Nurse Supervisons, 13.6% of Nurse Directors and 4.5％ of educational coordinator for Nurses. These participant had nurse-midwifery lincences by 63.64%. None of there had just midwifery lincences. 2, Age structures of the study population shows 31.82% of whom are.26-30 years and 22.73% of whom are 36. 40 years of age. This shown that seniority proportion is higher than the younger. There are 31.82% of 1-5 years, 27.27% of 6-10 year and 11-15 years, respectively by work career. 3. There are 54.55% of the institutions have opened their own midwifery training course for their nursing staff members. Because of lack of the facilities, shortage of instructors, and problems of administrative process. 4. According to the institution which opened for midwifery training courses, the participant was responsible for “midwifery”“Infant care”“MCH”“practice of midwifery”“Nursing adjustment”and“F. P.”5. During the midwifery couse, there were 8 institution who used the textbook and 4 institution who did not. Least of there referned to content matinals which was given by the sponsored. 6. There are 7 insititues who kept their training courses with other professional helps such as physicians., professiors and nurses. Some problems are pointed out by respondents such as“conflict with residents”“poor suportive administration”and“lake of manpower”. 8. The participant showed that they learned new knowledge as trends during this programs for there quality work so it need (one or twice times) a year. But they suggested that it needed more emphasis on the“maternal health care”and“role of the nurse-midwifery”. 9. The analysis of the results are as follows within the 6 areas which are given by the sponsored: There are highest ranks between“basic theory & family planning”“role of midwifery & nursing practice”. In the prenatal care the highest rank ware related to“health risk”on“idenify of risk symtoms”. In the health care areas which related to delivery, the responsers were related to“general conditions”or“high risk criteria”. In the health care area which related to high risk maternity care. In the neonatal health care, the highest rank was related to”health assessment of normal infant”. In the infant health care the responses was related to“abnormal symptoms”and“risk symptoms”. Actually, the participants show that they are more interested in“role of midwifery”“health assessment”and “high risk maternity care”are which emphasised on health promotion, health maintenance & disease preventive. 1) The midwifery training program need higher education for midwifery on a regular basis. 2) Within the open institution of midwifery training program, the nurses must be supported by their own institution and administry of social welfare must give systematic support. Also non-open institution must be open very soon. 3) All health workers including the residents & other workers, must cooperate for their phased common good of impovement of the maternity health. 4) Administration agonies & education institutions must provide the curriculum facilitis and administration systems which are needed for training of nurse-midwifery.

The purpose of this study was to make and ascertain a decision making process on the base of patient-oriented utilitarianism in the treatment of patients of chronic adult periodontitis. Fifty subjects were chosen in Yonsei Dental hospital and the other fifty were chosen in Severance dental hospital according to the selection criteria. Fifty four patients agreed in this study. NS group(N=32) was treated with scaling and root planing without any surgical intervention, the other S group(N=22) done with flap operation. During the active treatment and healing time, all patients of both groups were educated about the importance of oral hygiene and controlled every visit to the hospital. When periodontal treatment needed according to the diagnostic results, some patients were subjected to professional tooth cleaning and scaling once every 3 months according to an individually designed oral hygienic protocol. Probing depth was recorded on baseline and 18 months after treatments. A questionnaire composed of 6 kinds(hygienic easiness, hypersensitivity, post treatment comfort, complication, functional comfort, compliance) of questions was delivered to each patient to obtain the subjective evaluation regarding the results of therapy. The decision tree for the treatment of adult periodontal disease was made on the result of 2 kinds of periodontal treatment and patient's ubjective evaluation. The optimal path was calculated by using the success rate of the results as the probability and utility according to relative value and the economic value in the insurance system. The success rate to achieve the diagnostic goal of periodontal treatment as the remaining pocket depth less than 3mm and without BOP was $0.83{\pm}0.12$ by non surgical treatment and $0.82{\pm}0.14$ by surgical treatment without any statistically significant difference. The moderate success rate of more than 4mm probing pocket depth were 0.17 together. The utilities of non-surgical treatment results were 100 for a result with less than 3mm probing pocket depth, 80 for the other results with more than 4mm probing pocket depth, 0 for the extraction. Those of surgical treatment results were the same except 75 for the results with more than 4mm. The pooling results of subjective evaluation by using a questionnaire were 60% for satisfaction level and 40% for no satisfaction level in the patient group receiving nonsurgical treatment and 33% and 67% in the other group receiving surgical treatment. The utilities for 4 satisfaction levels were 100, 75, 60, 50 on the base of that the patient would express the satisfaction level with normal distribution. The optimal path of periodontal treatment was rolled back by timing the utility on terminal node and the success rate, the distributed ratio of patient's satisfaction level. Both results of the calculation was non surgical treatment. Therefore, it can be said that non-surgical treatment may be the optimal path for this decision tree of treatment protocol if the goal of the periodontal treatment is to achieve the remaining probing pocket depth of less than 3mm for adult chronic periodontitis and if the utilitarian philosophy to maximise the expected utility for the patients is advocated.

교착성 세기관지염은 매우 드문 소기도질환의 하나로서 변리학적으로 증식성 세기관지염과 더불어 폐쇄성 세기관지염의 양축의 하나를 점하고 있다. BOOP로 대표되는 증식성 세 기관지염은 임상경과가 비교적 빠르고 방사선학적으로도 간질성 또는 폐포성 음영 을 동반하는 비정형 폐렴과 유사한 발현을 보이므로 실제의 빈도가 적지 않다는 점은 제외하더라도 비교적 쉽게 의심하고 진단에 이를 수 있는 질환인 반면, 교착성 세기관지염은 그 빈도 자체가 매우 드물 뿐더러 방사선 소견이 거의 정상이고 폐기능검사 소견도 폐쇄성 양상을 보이므로 임상적으로 대개는 만성폐쇄성폐질환으로 간과되기 쉬운 질환으로써 그 진단이 쉽지 않다. 치료적인 면에서도 증식성 세기관지염이 부신피질호르몬제에 대해 극적인 반응을 보이는 반면 교착성 세기관지염은 세기관지벽 전체가 섬유성 반흔으로 대치되어 비가역성 기도폐쇄가 초래하는 병리학적 특성이 시사하는 바와 같이 치료에 대한 반응이 매우 미약한 치명적 질환이다. 그 원인으로서는 증식성 및 교착성 세기관지염 모두에서 독성 물질에 의한 흡입성 폐손상, 약제성, 감염성, 교원질환 관련성, 장기 이식 후등 선행 요인이 있는 경우와 원발 요인이 없는 경우를 특발성이라 한다. 같은 선행 요인에 의해 두가지 다른 질환군이 초래된다는 사실에서 이들이 같은 질환의 한 spectrum상에 있다는 설명도 있고, 여러 원인에 대해 같은 조직 소견이 관찰된다는 점에서 질환 특이적 병리 소견이라기보다는 비특이적 조직 반응의 하나라는 설명도 있지만 이에 대해서는 추후 연구가 필요한 실정이다. 저자 등은 비 Hodgkin 림프종을 진단 받은 동일한 시점에서 비교적 빠르게 진행하는 만성기도폐쇄 양상을 나타내고, 만성폐쇄성폐질환에 대한 위험 인자가 없고 흉부 방사선 소견상 정상소견을 나타내는 47세 여자 환자에서 개흉폐생검을 실시하여 교착성 세기관지염을 진단하였기에 문헌 고찰과 함께 보고하는 바이다. 상기한 선행 요인이 확인되지 않아 특발성이라 판단되며, 악성 종양, 특히 림프종과의 관련성 여부에 대해서는 현재로서는 확언하기 어렵고 향후 연구가 필요한 사항이라 생각된다.

본 연구에서는 일반생강과 법제생강의 대장염 염증에 대한 억제 효과와 법제의 가공 처리가 일반생강의 염증 억제 효과보다 우수한 지를 비교하였다. Balb/c 수컷 마우스에 2.5% DSS로 궤양성 대장염을 유도하고, 일반생강과 법제생강 추출물 500 mg/kg을 투여하여 대장염의 염증 억제 효과를 연구하였다. 일반생강과 법제생강은 70% 에탄올로 열수 추출 및 농축하여 실험에 사용하였다. 일반생강과 법제생강 추출물 투여군 모두 대장 길이의 축소와 체중 감소가 대조군보다 유의적으로 억제되었다(P<0.05). 일반생강과 법제생강 추출물 투여군의 대장 길이는 7.6 cm와 8.0 cm로 법제생강 추출물 투여군의 대장 길이가 일반생강 추출물 투여군보다 더 길었다. 대장의 조직학적 관찰에서 대장의 길이의 축소 정도가 증가함에 따라 대장조직 점막층의 선와부의 파괴도 증가되었다. 대장염 염증 초기에 증가하는 염증성 biomarker인 혈청에서의 IFN-${\gamma}$, IL-6, TNF-${\alpha}$ 및 IL-12의 농도는 일반생강 추출물 투여군보다 법제생강 추출물 투여군에서 유의적으로 더 감소하였고, 대장 조직에서의 이들 사이토카인의 유전자 발현도 같은 경향을 나타내었다(P<0.05). 대장염 조직에서의 염증성 인자인 iNOS, COX-2의 유전자 발현에서도 일반생강군보다 법제생강군의 유전자 발현이 더 유의적으로 감소되었다. 이상의 결과로 DSS로 대장염이 유도된 마우스에서 일반생강과 법제생강의 추출물은 항 염증성 효과를 나타내었고, 법제생강 추출물의 대장염 염증 억제 효과가 일반생강 추출물보다 더 우수하였으며, 이는 법제가공 처리에 의해서 일반생강의 대장염 염증 억제효과가 증가되었다고 사료된다.

포유류 난포의 폐쇄 과정은 매우 정교한 내분비적 조절작용에 의해 일어나며, 이 과정중에 발생하는 난포 내 과립세포의 퇴화는 핵응축 현상을 동반하는 것으로 알려져 있다. 본 연구는 핵응축 현상과 관련하여 돼지 난소 내 폐쇄난포의 과립세포가 퇴화 시 동반되는 세포 사멸이 아포토시스의 과정에 의해서 일어나는지의 여부와 아포토시스 관련 주요 단백질 분해 효소인 캐스파제-3과 연관된 세포 사멸 기전과 관련이 있는지에 대해서 조사하고자 하였다. 돼지 난소로부터 정상 및 폐쇄난포를 분리하고 이들을 대상으로 조직학적으로 아포토시스 발생 여부를 확인하였고 난포로부터 각각 얻어진 과립세포를 대상으로 하여 아포토시스 과정으로 사멸하는 세포의 형태 및 캐스파제-3의 활성을 관찰 및 측정하였다. 폐쇄 중 돼지 난포 내 과립세포에서 핵의 분절이 흔히 관찰되었고, 유세포 측정기를 이용하여 세포 사멸율을 측정해 본 결과 사멸하는 세포의 수가 폐쇄난포의 과립세포에서 정상난포보다 매우 유의하게 높은 것으로 나타났다. 난포 조직 내 아포토시스 세포는 과립세포에 국한되어 관찰되었으며 협막세포에서는 아포토시스가 관찰되지 않았다. 최종적으로 캐스파제-3의 활성을 정상 및 폐쇄 난포에서 분리한 세포에서 측정해 본 결과 폐쇄난포의 과립세포에서 정상난포보다 유의하게 높은 활성을 보였다. 이와 같은 결과를 종합해 볼 때, 돼지 난포의 폐쇄 중 과립세포의 퇴화는 아포토시스 과정에 의해 일어나며, 캐스파제-3의 활성에 의존적인 것으로 사료된다.

A Macroscopic combination of two or more distinct materials is commonly referred to as a "Composite Material", having been designed mechanically and chemically superior in function and characteristic than its individual constituent materials. Composite materials are used not only for aerospace and military, but also heavily used in boat/ship building and general composite industries which we are seeing increasingly more. Regardless of the various applications for composite materials, the industry is still limited and requires better fabrication technology and methodology in order to expand and grow. An example of this is that the majority of fabrication facilities nearby still use an antiquated wet lay-up process where fabrication still requires manual hand labor in a 3D environment impeding productivity of composite product design advancement. As an expert in the advanced composites field, I have developed fabrication skills with the use of machinery based on my past composite experience. In autumn 2011, the Korea government confirmed to fund my project. It is the development of a composite sanding machine. I began development of this semi-robotic prototype beginning in 2009. It has possibilities of replacing or augmenting the exhaustive and difficult jobs performed by human hands, such as sanding, grinding, blasting, and polishing in most often, very awkward conditions, and is also will boost productivity, improve surface quality, cut abrasive costs, eliminate vibration injuries, and protect workers from exposure to dust and airborne contamination. Ease of control and operation of the equipment in or outside of the sanding room is a key benefit to end-users. It will prove to be much more economical than normal robotics and minimize errors that commonly occur in factories. The key components and their technologies are a 360 degree rotational shoulder and a wrist that is controlled under PLC controller and joystick manual mode. Development on both of the key modules is complete and are now operational. The Korean government fund boosted my development and I expect to complete full scale development no later than 3rd quarter 2012. Even with the advantages of composite materials, there is still the need to repair or to maintain composite products with a higher level of technology. I have learned many composite repair skills on composite airframe since many composite fabrication skills including repair, requires training for non aerospace applications. The wind energy market is now requiring much larger blades in order to generate more electrical energy for wind farms. One single blade is commonly 50 meters or longer now. When a wind blade becomes damaged from external forces, on-site repair is required on the columns even under strong wind and freezing temperature conditions. In order to correctly obtain polymerization, the repair must be performed on the damaged area within a very limited time. The use of pre-impregnated glass fabric and heating silicone pad and a hot bonder acting precise heating control are surely required.
