  • 본 연구의 목적은 수면상태 분석을 위한 분류기를 설계해줌과 동시에 생체신호를 기반으로 하여 수면상태 판별에 유효한 주요 특징벡터들을 추출함에 있다. 수면은 인간의 삶에 중요한 영향을 끼친다. 따라서 사람들이 수면부족 혹은 수면장애를 겪게 되면 집중력 감퇴, 인지기능 장애 등의 문제를 가질 우려가 생기게 되므로, 수면단계 판별에 관한 많은 연구들이 이루어지고 있다. 본 연구에서는 피험자가 수면을 취하는 동안 피험자의 생체신호를 획득하였다. 획득 된 생체신호로부터 필터링 등의 전처리 과정을 통하여 특징들을 추출하여 주었다. 추출된 특징들은 유전 알고리즘과 신경망을 결합하여 만든 새로운 알고리즘의 입력으로 사용되었으며, 알고리즘은 수면단계 분석을 위하여 높은 가중치를 가지는 특징을 선택하여 주었다. 이에 따른 결과로 뇌파 신호와 심전도 신호 모두 사용 시 알고리즘의 정확도는 약 90.26%가 나왔으며, 선택되어진 특징은 뇌파 신호의 ${\alpha}$파와 ${\delta}$파의 주파수 파워와 심전도 신호의 SDNN(Standard deviation of all normal RR intervals)이다. 선택된 특징은 수면상태를 분류하는데 중요한 역할을 함을 알고리즘을 반복적으로 수행하여 확인하였고, 이 연구는 추후 수면장애의 진단 혹은 수면분석의 지침을 만드는데 사용가능할 것으로 사료된다.

  • The Community Health Service considers the family as a service unit and places the emphasis of its service on the health problems and the nursing needs of the family rather than the individual. From the conceptual point of view that tile community health service is both health maintenance and health promotion of the family, the community health nurse should have a knowledge of the growth and development of the family and be responsible for the comprehensive support of normal family development. The community health nurse often is in a position to make a real contribution to normal family development. In order to investigate the relationship between the areas of nursing need and family development, the following objectives were established 1. To discover the general characteristics of the study population by the stage of family development. 2. To discover specific nursing needs in relation to the family developmental stage, and to determine the intensity of the nursing needs and the ability of the family to cope with these needs. 3. To discover overall family health nursing problems in relation to the family developmental stage and determine the intensity of the nursing need and the problem solving ability of family. Definitions : The family developmental stages as classified by Dually were used stage 1. Married couples(without children) stage 2. Childbearing Families (oldest child birth to 30 months of age) stage 3. Families with preschool children (oldest child 2½-to 6 years) stage 4. Families with schoolchildren (oldest child 6 to 13 years). stage 5. Families with teenagers (oldest child 13 to 20 years) stage 6. Families as launching centers (first child gone to last child′s leaving home). stage 7. Middle- aged parents (empty nest to retirement) stage 8. Aging family member (retirement to death of both spouses) The areas of nursing need were defined as those used in the study, "A Comprehensive Study about Health and Nursing Need and a Social Diagram of the Community", by tile Nursing research Institute and Center for population. and Family Planning, July 1974. The study population defiled and selected were 260 nuclear families ill two myron of Kang Hwa Island. Percent, mean value and F- test were utilized in tile statistical analysis of the study result. Findings : 1. General characteristics of the study population by tile family developmental stage ; 1)The study population was distributed by the family developmental stage as follows : stage 1 : 3 families stage 2 : 13 families stage 3 : 24 families stage 4 : 41 families stage 5 : 50 families stage 6 : 106 families stage 7 : 13 families stage 8 : 10 families 2) Most families had 4 or 5 members except for those in stage, 1, 7, and 8. 3) The parents′ present age was older in the higher developmental stage and their age at marriage was also younger in the higher developmental stages. 4) The educational level of parents was primarily less than elementary school irrespective of the developmental stage. 5) More than half of parents′ occupations were listed as laborers irrespective of the developmental stage, 6) More than half of the parents were atheists irrespective of the developmental stage. 7) The higher the developmental stage(from stage 2 to stage 6 ), the wider the distribution of children′s ages. 8) More than half of the families were of middle or lower socio-economic level. 2. Problems in specific areas of nursing need by family developmental stage, the intensity of nursing need and the problem solving ability of the family : 1) As a whole, many problems, irrespective of the developmental stage, occurred in tile areas of Housing and Sanitation, Eating Patterns, Housekeeping, Preventive Measures and Dental care. Problems occurring ill particular stages included the following ; stage 1 : Prevention of Accident stage 2 : Preventive Vaccination, Family Planning. stage 3 : Preventive Vaccination, Maternal Health, Family Planning, Health of Infant and Preschooler. stage 4, 5 : Preventive Vaccination, Family Planning, Health of School Children. stage 6 : Preventive Vaccination, Health of School Children. 2) The intensity of the nursing need in the area of Acute and Chronic Diseases was generally of moderate degree or above irrespective of the developmental stages except for stage 1. Other areas of need listed as moderate or above were found in the following stages: stage 1 : Maternal Health stage 3 . Horsing and Sanitation, Prevention of Accident. stage 4 . Housing and Sanitation. stage 5 : Housing and Sanitation, Diagnostic and Medical Care. stage 6 : Diagnostic and Medical care stage 7 : Diagnostic and Medical Care, Housekeeping. stage 8 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Dental Care, Eating Patterns, Housekeeping. 3) Areas of need with moderate problem solving ability or less were as follows : stage 1 : Diagnostic and Medical Care, Maternal Health. stage 2 : Prevention of Accident, Acute and Chronic Disease, Dental Care. stage 3 : Housing and Sanitation, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of Infant and preschooler, Eating Patterns. stage 4 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of New Born, Health of Infant and Preschooler, Health of school Children, Eating Patterns, Housekeeping. stage 5 . Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Preventive Vaccination, Maternal Health, Eating Patterns. stage 7, 8 : Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measures, Dental Care, Preventive Vaccination, Eating Patterns , Housekeeping. Problem occurrence, the degree of nursing need and the degree of problem solving ability 1 nursing need areas for the family as a whole were as follows : 1) The higher the stages(except stage 1 ), the lower the rate of problem occurrence. 2) The higher the stage becomes, the lower the intensity of the nursing need becomes. 3) The higher the stages (except stages 7 and 8), the higher. the problem solving ability. Conclusions ; 1) When the nursing care plan for the family is drawn up, depending upon the stage of family development, higher priority should be give to nursing need areas ① at which problems were shown to occur ② where the nursing need is shown to be above moderate degree and ③ where the problem solving ability was shown to be of moderate degree. 2) The priority of the nursing service should be Placed ① not on those families in the high developmental stage but on those families in the low developmental stage ② and on those areas of need shown in stages 7 and 8 where the degree nursing need was high and the ability to cope low.

  • Many studies for verifying angiogenesis have been in progress, especially in the field of abnormal vascular proliferation to explain the pathogenesis and to develop a treatment of several diseases. In our previous experiments, endothelial cell proliferations were induced by DMH stimulation in vitro, and the 177 factors(142 up-regulated and 35 down-regulated factors) were identified. Among the up-regulated factors, 9 substances (EFEMP1, CTGF, CYR61, $ITG{\beta}1$, FHL2, SERPINE1, MYC, PTTG1 and MSH6) were selected, which were related to cell proliferation and showed high signal intensities. The RNA was isolated from HUVECs at the time of 0, 6, 12, 24 hours after the DMH treatment, and RNA of control group HUVECs was also isolated. Genetic information of selected molecules was used to make primer for each, and RT-PCR was performed to analyze both groups. In control and treatment groups, each substance presented variety of manifestation degree according to time differences. EFEMP1, CTGF, CYR61, $ITG{\beta}1$, FHL2 and MYC were related to abnormal vascular proliferation steadily and SERPINE1, PTTG1 and MSH6 were related secondarily. CTGF was related to both normal and abnormal proliferation, but it played a more significant role in abnormal proliferation from earlier stage. EFEMP1, CYR61, $ITG{\beta}1$, FHL2 and MYC were similar to CTGF, although the relation appeared lately. Further study should be performed to analyze the expressions and the interactions of growth factors, which could be utilized in the new therapeutic development.

  • The objective of this study is to identify the kinematic variables of giant swing backward to handstand as well as individual variations of each athlete performing this skill, which in turn will provide the basis for developing suitable training methods and for improving athlete's performance in actual games. For this end, 3 male athletes, members of the national team, who are in ${\Box}{\Box}H{\Box}{\Box}$ University, have been randomly chosen and their giant swing backward to handstand performance was recorded using two digital cameras and analyzed in 3 dimensional graphics. This study came to the following conclusion. 1. Proper time allocation for giant swing backward to handstand are: Phase 1 should provide enough time to attain energy for swing track of a grand round movement. The phase 3 is to throw the body up high in the air and stay in the air as long as possible to smoothen up the transition to the next stage and the phase 4 should be kept short with the moment arm coefficient of the body reduced. 2. As for appropriate changes of locations of body center, the phase 1 should be comprised of horizontal, perpendicular, compositional to make up a big rotational radius. Up to the Phase 3 the changes of displacements of vertical locations should be a good scale and athlete's body should go up high quickly to increase the perpendicular climbing power 3. When it comes to the speed changes of body center, the vertical and horizontal speed should be spurred by the reaction of the body in Phase 2 and Phase 3. In the Phase 4, fast vertical speed throws the body center up high to ensure enough time for in-the-air movement. 4. The changes of angles of body center are: in Phase 2, shoulder joint is stretching and coxa should be curved up to utilize the body reaction. In the Phase 4, shoulder joint and coxa should be stretched out to get the body center as high as possible in the air for stable landing. 5. The speeds of changes in joints angles are: in the Phase 2 should have the speed of angles of shoulder joints increase to get the body up in the air as quickly as possible. The Phase 3 should have the speed of angles in shoulder joint slow down, while putting the angles of a knee joint up to speed as quickly as possible to ensure enough time for in-the-air movement.

  • This study aims to analyze the characteristics of post-epic theatre in the Belgian theatre director Jan Lauwers' trilogy titled in "Happy Face/Sad Face": (2004), (2006) and (2008). I regard that it played a very important junction for him to create his own theatrical style compared to earlier years. From this period, Lauwers has tried to create his original plays in order to concentrate the story of our era and has showed to combine a variety of media such as dance, installation, video, singing etc. In this context, I would like to study his own theatricality from the three perspectives of dramaturgy, directing and acting largely based on Hans-Thies Lehmann's theory of post-epic theatre, who pointed out the significance of Lauwer's theatrical leading role very early. First, from the dramaturgical point of view, we need to pay attention to the theme of translunary death; where the living and the dead coexist on the stage. In fact, death is the theme that Lauwers has been struggling to research for quite long time. In his trilogy, the dead never exits the stage. The dead, who is not a representative tragic character, even meddles the things among or with the living and provide comments to people. As a consequence, it happens to reduce a dramaturgical strong tension, leads depreciation of suspense and produces humanism in a way. This approach helps to create his unique comical theatrical atmosphere even though he deals with the contemporary tragic issues such as war, horror and death. Second, from the directing point of view, it is worth to take a look at the polyphonic strategy in terms to applying various media. Among all the things, the arts of dancing and singing in chorus are actively applied in Lauwer's trilogy. The dance is used in individual and microscopic way, on the other hand, singing shows collective and is a macroscopic quality. The dance is the representing media to show Lauwer's simultaneous microscopic mise-en-scene. While main plot takes place around the center-stage, actors perform a dance around the off-centered stage. Instead of exiting from the stage during the performance, the actors would continue dance -sometimes more like movements- around the off-centered stage. This not only describes the narrative, but also shows how each character is engaged to the main plot or incident, and how they look into it as a character. Its simultaneous microscopic mise-en-scene intends to function such as: showing a variety moments of lives, amplifying some moments or incidents, revealing character's emotion, creating illusionary theatrical atmosphere and so on. Meanwhile, singing simple lyrics and tunes are an example of the media to stimulate the audiences' catharsis. As the simple melody lingers in the audiences' mind, it ends up delivering a theatrical message or theme after the performance. This message would be transferred from the singing in chorus functions as a sort of leitmotive in order to make an impression to the audience. This not only richens their emotion but also creates an illusionary effect. Third, from the acting perspective, I'd like to point out the "detachment" aesthetic which Lehmann has pointed out. The actors never go deep into the drama by consistently doing recognize a theatrical illusion. The audience happens to pay attention to their presence through the actor's deliberate gesture, business, movement, rhythm, language, dance etc. The actors are against forming closed action by speaking in various languages or by revealing deliberately stage directions or acts, and by creating expressive mise-en-scene with multiple media. As a consequent, the stage can be transformed to not a metaphoric but a metonymic place. These actions are the ultimate intention for a direct effect to the audience. So to speak, Lauwers uses the anti-illusionary theatrical method: the scenes of fantastic death, interruption of singing and dance, speaking many kinds of languages, acting in detachment-status and so on. These strategies function to make cracks in spectators' desire who has a desire to construct a linear narrative. I'd like to say that it is the numerous potentiality to let the reality penetrate though and collide the reality with a fiction. By doing so, it induces for spectators to see the reality in the fiction. As Lehmann says, "when theatre presents itself as a sketch and not as a finished painting, the spectators are given the chance to feel their own presence, to reflect on it, and to contribute to the unfinished character themselves". In this sense the spectators can perform an objective criticism on our society and world in Lauwer's theatre because there are a number of gaps and cracks in his theatrical illusion where reality can penetrate. This is also the point that we can find out the artists' responsibility in this era of our being.

  • I. Introduction: In management control, business analysis has to do with a performance evaluation and is accounted much of manager's decision making, Business indicator accounting is the vehicle of decision making and also feedback can be accomplished by it. This study is to build up a logic about what capacity for use the business indicator accounting has in making decision. Therefore it is significant to make clear the adjustment of decision and to study the function of business indicator. II. Adjustment of Decision and Accounting Work: Adjustment of decision is connected with accounting now that business indicator accounting has a function of decision making. And it should be tied up with specialization as a structure of system, organization, communication and stage system. III. Adjustment of Decision and Managerial Accounting: Managerial account makes a great contributin to the management in which each adjustment of decision should be accomplished. Let me make mention of how the adjustment of decision is accomplished concretely, and what contribution che managerial accounting makes. In an adjustment of decision, centralization and decentrialization of enterprise are very import and I think the three problems, such as the extent of sphere (procurement, production and maketing), the face of affairs (planning, implementing and controlling), the final surge (decision making and action) can be accomplished by the business indicator accounting. IV. Structure of System and Disciplinary Approach for Decision: Decision can be classified into syncronized decision and continuous decision, and is closely connected with centralization and decentralization. In the course of systematizing, the sort of decision is classified into a man in charge of decision, and object of decision, conditions of decision, and an adjusting of decision. For it's object, it has an analogical thinking and an analytic subdivision about the target area. And it is premised on getting a scientific understanding. I think a disciplinary approach remains in solving these intricate problems. V. Conclusion: In this study I dealt with a specialization as a structure in management system and a theory that adjustment is a necessary process in decision making. For an adjustment of decision, exchanging informations and communication are necessary, and accounting is in charge of the process. And then the centralization and decentralization of decision should be connected in the way of adjustment of decision. In case of decentralization, the adjustment of decision is accomplished by the exchanging informations through feedback, and in case of centralization, by the all-round planning. And also I found that syncronized decision and decentralized decision are linked together. It is natural that the function of business indicator accounting is called for to render more services for it. Therefore, according to the extent of centralization and decentralization accounting to adjust the decision, can be various. Consequently, in relation to the structure of system. I think it is necessary to make a theoretical and empirical study of the business indicator accounting.

  • 현장에서 널리 활용하고 있는 침하예측기법으로는 Hyperbolic법, Hoshino법, Monden법 등이 있다. 이들 기존 침하예측법은 최종침하량 예측이 최종 성토단계가 완료된 이후 가능하다는 단점을 가지고 있다. 본 연구에서는 이와 같은 기존 예측법의 단점을 보완할 수 있는 새로운 침하량 예측법(SPSFC: Settlement Prediction for Staged Filling Construction)을 제안하였다. 이 방법은 연약지반에서 성토 완료 후뿐만 아니라, 초기 성토단계에서 단계성토별 시간-침하곡선을 예측할 수 있다. SPSFC법을 검증하기 위해 연약지반 개량을 위한 배수공법이 적용된 낙동강 하구 지역 두 개 현장에서 계측된 자료를 이용하여 기존 예측기법과 함께 SPSFC법으로 장래침하량을 예측하였다. 비교 결과, SPSFC법으로 예측된 침하량이 기존 예측법과 비교해서 신뢰성이 있음을 확인하였다. 또한 SPSFC법으로 초기 성토 단계에서 침하계측자료를 분석하여 예측에 필요한 지반상수를 구하고 이것을 이용하여 나머지 단계 성토 시 발생할 시간-침하량 곡선을 도시하였다. SPSFC법으로 예측된 침하량이 계측치와 잘 일치하는 것으로 나타나 SPSFC법으로 초기 성토단계의 침하계측 값만을 가지고 장래 침하량 예측이 가능함을 확인하였다.

  • 영화 <남산의 부장들>은 다른 10.26 사건 소재의 콘텐츠와 달리 대립되는 인물 간의 치열한 심리 대결을 표방한 연극적 성격이 짙은 '분노 캐릭터' 영화라는 점에 착안해 본 연구에서는 라코프와 코브시스(Lakoff & Kövecses) 등이 제시한 '분노의 5단계 모델'을 적용해 장면을 단위로 설정해 서사구조를 내용 분석하였다. 그 결과 이 영화는 심리학의 분노 5단계 이론을 잘 반영해 주인공의 분노 결행에 대한 인과성과 개연성을 한층 높인 것으로 나타났다. 특히 분노조절(25분)에 가장 긴 시간을 할애해 응징·보복의 동기를 정당화한 반면 통제력 상실(14분)에 가장 짧은 시간을 부여해 응징 행동의 긴박감을 극대화 하고자한 것으로 분석되었다. 각 단계에서 분노를 유발하는 기폭제 역할은 무시, 모멸, 오만, 과시, 놀림, 조롱, 무단 개입, 수군거림, 비아냥, 말 가로채기 언행으로 각 단계마다 2~6회씩 배치되었다. 특히 '경호실장'역의 경우 조롱 발언이, '박통'역의 경우 친구도 죽인 무도한 인간이란 극심한 모멸감을 야기하는 발언이 주인공으로 하여금 복수를 실행하도록 하는 결정적인 '분노 방아쇠'로 작용하였다. 결론적으로 이 영화는 서사구조가 분노이론을 정교하게 따랐다. '정치극'이라서 서사의 전개에서 분노의 공적(公的) 사유를 많이 설정하는 것이 일반적인데도 분노유발목록(PI)과 24%나 일치할 정도로 관객들이 흔히 겪는 일상의 분노사례를 적잖이 반영한 것으로 확인되었다. 이상과 같이 제작진이 이 영화에 심리학의 분노이론을 정교하게 반영하고 분노의 공적·사적 동인(動因)을 균형 있게 안배한 것은 분위기가 무겁고 낯설기 마련인 정치영화에 대한 관객들의 이해도와 흡인력을 높이려는 소통강화 의도에서 비롯된 것이라 평가된다.

  • Instead of fertilizing the lands they moved to find other fertile lands and lived a feudal life agriculture and various machincs played a main role in the land reclamation. The best method of land clearing, the time and capacity in the operation and the effect of growing crops should systematically analized prior to the time of 3rd Five-year Economic Development(1972-1976) in order to cultivate 210,000ha of wasteland or the modernization of our country. The present study was investigated to find out a new working-system of mechanical land clearing and development of fertile soil. The results are as follows: 1) The first stage of productive power increases when weeds were mixed soil in the land clearing work in order to supply organic materials and to make soil swollen instead of burning or just removing. 2) The equipments such as bulldozers, harrows, power tillers and so on should be prepared in order to do a systematic work in the land clearing. 3) The work of pulling-up roots is dependent upon the forms of roots spreading under the ground. The work of the pulling-up of the straight roots was most difficult. But before the roots are pulling-up we do not know the forms of roots. 4) The cutting of soil from upside to under side land clearing method (II) Spent 6 hr 7 min 43 sec per 1 Danbo in doing land clearing and control method spent 4 hr 52 min 30 sec per 1 Danbo in doing land cearing. No significant difference could be found between II treatment type and I treatment type. 5) The volume of soil carried by bulldozer $270.38m^3$ per 1 Danbo in I type and in II type, $368.58m^3$ per 1 Danbo or about 36% increased in II type then in I type. But that is not a significant difference when considering the whole productive power of soil. 6) The land clearing of terrace by bulldozers cannot escape making the embankment slope of about $45^{\circ}$, and 25.3% should be decreased in the area. It is recommended to make use of the embankment slope by planting grass for cows. 7) The time of retary tilling increased 2.3 times or 1 hr 42 min 22 sec per 1 Danbo compared to the timesrequired in the harrowing. Because it mixed the Organic matter on ground and the harrowing of subsoil. 8) The havest of pasture growing on the land reclamation in natural slope is as follows. (a) The none fertilizers with reclaimed block of productivity decresed 1/10 than that of the farmland. Therefore the none fer tilizing in the cultivated pasture is unprofitable. (b) The havest of the manured IV treatment block was the best not only in the kinds of fertilizers but also in the kinds of pasture grass.
