실버세대의 중요성은 인구 증가뿐만 아니라 구매력의 향상 및 의사 표현의 강도가 증가하면서 더욱 커지고 있다. 이에 따라 과거 실버세대 전체를 대상으로 접근하던 마케팅 전략은 실버세대의 특성에 따라 적절히 분류하여 접근하는 방식으로 수정되는 것이 적절하다. 또한 세분군 분류 결과에 따라 고객 접근 전략이 결정되므로, 세분군이 얼마나 동일한 특성을 보유하고 있는 지는 마케팅 계획 수립에 매우 중요한 요소가 된다. 따라서 이론적으로 동일 세분군에 속해 있는 고객의 니즈는 대체로 일치해야 한다. 본 연구에서는 실버세대의 생활 행태와 생애 단계를 감안하여, 실버 세대 대상의 마케팅을 위한 세분군 (細分群) 분류를 수행하였으며, 분류된 세분군의 니즈가 얼마나 일치하고 있는지를 측정하기 위하여 동질도 (DoH: Degrees of Homogeneity)를 측정하였다. 동질도는 각 세분군을 대상으로 수행된 설문조사의 객관식 문항 별로 최다 응답자가 선택한 보기 문항이 다른 문항에 비하여 유의미하게 많다고 판단되는 문항의 수를 전체 문항의 수로 나눈 것으로 정의하였다. 본 연구는 동질도를 활용한 세분군 분류 결과의 적절성 평가 방법을 제시하였다는데 의의가 있으며, 다양한 분야에서 응용될 수 있을 것으로 판단된다. 또한 본 연구에서 제시한 실버세대 세분군 분류 결과는 점차 증가하고 있는 실버세대를 위한 마케팅 방안 수립의 기본 자료로 활용될 수 있을 것으로 판단된다.

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.

Visual media transmits image and information reproduced in large quantities, such as a photography, film, television, video, advertisement, or computer image. Correspondence to the students' reception and recognition of culture in the future. arrangements for the field of studies of visual culture. 'Visual Culture' implies cultural phenomena of visual images via visual media, which includes not only the categories of traditional arts like a painting, sculpture, print, or design, but the performance arts including a fashion show or parade of carnival, and the mass and electronic media like a photography, film, television, video, advertisement, cartoon, animation, or computer image. In the world of visual media, Image' functions as an essential medium of communication. Therefore, people call the culture of today fra of Image Culture', which has been converted from an alphabet convergence era to an image convergence one. Image, via visual media, has become a dominant means for communication in large part of human life, so we can designate an Image' as a typical aspect of visual culture today. Image, as an essential medium of communication, plays an important role in contemporary society. The one way is the conversion of analogue image like an actual picture, photograph, or film into digital one through the digitalization of digital camera or scanner as 'an analogue/digital commutator'. The other is a way of process with a computer drawing, or modeling of objects. It is appropriate to the production of pictorial and surreal images. Digital images, produced by the other, can be divided into the form of Pixel' and form of Vector'. Vector is a line linking the point of departure to the point of end, which organizes informations. Computer stores each line's standard location and correlative locations to one another Digital image shows for more 'Perfectness' than any other visual media. Digital image has been evolving in the diverse aspects, such as a production of geometrical or organic image compositing, interactive art, multimedia art, or web art, which has been applied a computer as an extended trot of painting. Someone often interprets digitalized copy with endless reproduction of original even as an extension of a print. Visual af is no longer a simple activity of representation by a painter or sculptor, but now is intimately associated with a matter of application of media. There is some problem in images via visual media. First, the image via media doesn't reflect a reality as it is, but reflects an artificial manipulated world, that is, a virtual reality. Second, the introduction of digital effect and the development of image processing technology have enhanced a spectacle of destructive and violent scenes. Third, a child intends to recognize the interactive images of computer game and virtual reality as a reality, or truth. Education needs not only to point out an ill effect of mass media and prevent the younger generation from being damaged by it, but also to offer a knowledge and know-how to cope actively with social, cultural circumstances. Visual media education is one of these essential methods for the contemporary and future human being in the overflowing of image informations. The fosterage of 'Visual Literacy' can be considered as a very purpose of visual media education. This is a way to lead an individual to the discerning, active consumer and producer of visual media in life as far as possible. The elements of 'Visual Literacy' can be divided into a faculty of recognition related to the visual media, a faculty of critical reception, a faculty of appropriate application, a faculty of active work and a faculty of creative modeling, which are promoted at the same time by the education of 'visual literacy'. In conclusion, the education of 'Visual Literacy' guides students to comprehend and discriminate the visual image media carefully, or receive them critically, apply them properly, or produce them creatively and voluntarily. Moreover, it leads to an artistic activity by means of new media. This education can be approached and enhanced by the connection and integration with real life. Visual arts and education of them play an important role in the digital era depended on visual communications via image information. Visual me야a of day functions as an essential element both in daily life and in arts. Students can soundly understand visual phenomena of today by means of visual media, and apply it as an expression tool of life culture as well. A new recognition and valuation visual image and media education is required to cultivate the capability of active, upright dealing with the changes of history of civilization. 1) Visual media education helps to cultivate a sensibility for images, which reacts to and deals with the circumstances. 2) It helps students to comprehend the contemporary arts and culture via new media. 3) It supplies a chance of students' experiencing a visual modeling by means of new media. 4) There are educational opportunities of images with temporality and spaciality, and therefore a discerning person becomes to increase. 5) The modeling activity via new media leads students to be continuously interested in the school and production of plastic arts. 6) It raises the ability of visual communications dealing with image information society. 7) An education of digital image is significant in respect of cultivation of man of talent for the future society of image information as well. To correspond to the changing and developing social, cultural circumstances, and the form and recognition of students' reception of them, visual arts education must arrange the field of studying on a new visual culture. Besides, a program needs to be developed, which is in more systematic and active level in relation to visual media education. Educational contents should be extended to the media for visual images, that is, photography, film, television, video, computer graphic, animation, music video, computer game and multimedia. Every media must be separately approached, because they maintain the modes and peculiarities of their own according to the conveyance form of message. The concrete and systematic method of teaching and the quality of education must be researched and developed, centering around the development of a course of study. Teacher's foundational capability of teaching should be cultivated for the visual media education. In this case, it must be paid attention to the fact that a technological level of media is considered as a secondary. Because school education doesn't intend to train expert and skillful producers, but intends to lay stress on the essential aesthetic one with visual media under the social and cultural context, in respect of a consumer including a man of culture.

제휴 로열티 프로그램(coalition loyalty program; 이하 CLP라고 한다)이란 하나의 로열티 프로그램 안에 다수의 제휴 기업들이 참여하며, 이들과 독립된 (로열티 프로그램 운영)기업이 관리하는 로열티 프로그램으로 정의된다(Blattberg 등 2008). 본 연구의 목적은 고객의 브랜드에 대한 사전 선호 수준에 따라, CLP가 고객 충성도를 증가시키는 원인과 제휴 네트워크 안의 주체 간 인식의 전이에 차이가 있을 것임을 밝히는 데에 있다. 고객 충성도의 동기는 전환장벽(switching barrier) 관점(Balabanis 등 2006; Colgate와 Lang 2001; Jones 등 2000)에 따라 자발적인 이유(브랜드 매력도)와 비자발적 이유 (브랜드 전환비용)로 설명하였다. CLP안에서 브랜드(비선호)-CLP-브랜드(선호)간 전이효과(spillover effect)는 인지적 일관성(Aaker과 Keller 1990; Hamilton 등 1989)과 정보 통합 이론(Anderson 1981; Simon과 Ruth 1998)을 적용하였다. 연구 결과는 다음 세 가지로 학문적 실무적 의의를 갖는다. 첫째, 브랜드에 대한 사전 태도에 따라 정보처리 경향이 달라진다는 소비자 행동 연구의 견해를 CLP 제휴 상황에서 검증하였다. 고객은 브랜드 선호가 높을수록 자발적 동기를 강화하고, 반대의 경우 비자발적 동기를 강화한다. 둘째, 브랜드에 대한 사전 태도가 해당 브랜드와 연관된 주체 간 인식 전이에 긍정적 조절효과를 함을 검증하였다. 즉 선호 브랜드와 어떤 주체가 연관될 때(비선호 브랜드와 연관된 경우에 비해) 인식의 전이가 더 많이 발생한다. 셋째, 기업이 CLP가입에 대한 전략적 선택을 할 때 마케팅 목적에 따라 고려해야할 사항이 달라진다. 기업의 목적이 충성고객의 유지라면, 로열티 프로그램 자체의 보상 방식과 활용 방식 등이 고려되어야한다. 하지만 목적이 비충성고객의 확보라면, 유명 브랜드의 제휴 여부를 따져야 한다. 또한 기업은 CLP의 효과(브랜드 충성도)에 안주할 것이 아니라 그 원인을 알아야 하는데, 비선호 브랜드처럼 비자발적 동기 강화에 따른 충성도 증가는 장기적으로 바람직하지 못하다는 견해가 있다(Egans 2001).

The increasing emphasis placed on the production of fine turf for lawns, golf courses, parks, and other recreational sites has led to many unsolved problems as to how such turf could be best established and mainteined. For this purpose, a series of experiments were conducted under con ditions of pot and field. The results obtained were as follows EXPERIMENT I. The effect of nitrogen fertilizer and clipping interval on Zoysia japonica. 1. Increasing the rate of nitrogen and frequent clipping increased tiller number of Zoysis japonica and the maximum number of tillers were obtained from 700 kg N application and freqnent clippings (10 days interval ) in October. Treatment of 350kg N with 10 days clipping interval increased tillers much more than those of 700 kgN with 20 and 30 days clipping intervals. 2. The average number of green leaves occurred during the growth period maximized by applying 700 kg N and clipping 10 days interval. 3. Increasing tiller numbers significantly decreased tops DM weight per tiller by clipping plants at interval of 10 and 20 days, irrespective of nitrogen applied, and with nil N, at the interval of 30 days. By applying 700 kg N, however, top DM weight per tiller increased as the number of tillers increased consistently. 4. The highest top DM weight was achieved from late August to early September by applying 350 and 700kgN. 5. During the growth period, differences in unders ( stolon + root ) DM weight occurred bynitrogen application were found between nil N and two applied nitrogen levels, whereas, at the same level of nitrogen applied, the increase in stolon DM weight enhanced by lengthening the clipping interval to 30 days. 6. Nitrogen efficiency to green leaves, stolon nodes and DM weight of root with high nitrogen was achieved as clipping interval was shortened. 7. By increasing fertilizer nitrogen rate applied, N content n the leaves and stems of Zoysiajaponica was increased. On the other hand, N content in root and stolon had little effect onfertilizer nitrogen, resulting in the lowest content among plant fractions. The largest content of N was recorded in leaves. Lengthening the clipping interval from 10 or 20 to 30 days tends to decrease the N content in the leaves and stems, whereas this trend did not appeared in stolon androot. 8. A positive correlations between N and K contents in tops and stolon were established andthus K content increased as N content in tops and stolon increased. Meanwhile, P content was not affected by N and clipping treatments. 9. Total soluble carbohydrate content in Zoysia japonica was largest in stolon and stem, and was reduced by increasing fertilizer nitrogen rate. Reduction in total soluble carbohydrate due to increased nitrogen rate was severer in the stolons and stems than in the leaves. 10. Increasing the rate of nitrogen applied increased the number of small and large vascular bundles in leaf blade, but shortened distance among the large vascular bundles. Shortening the clipping interval resulted in increase of the number of large vascular bundles but decrease ofdistance between large vascular bundles.EXPERIMENT II. Growth response of Zoysia japonica imposed by different plant densities. 1. Tiller numbers per unit area increased as plant density heightened. Differences in num ber between densities at higher densities than 120 D were of no significance. 2. Tiller numbers per clone attained by 110 days after transplanting were 126 at 40D,77 at 80D, 67 at 120D, 54 at 160D, and 41 at 200D. A decreasing trend of tiller numbers per clone with increasing density was noticable from 100 days after transplanting onwards. 3. During the growth period, the greatest number of green leaves per unit area were attainedin 90days after transplanting at 160D and 200D, and 100 days after transplanting at 40D, 80Dand 120D. Thus the period to reach the maximum green leaf number with the high plantdensity was likely to be earlier that with the low plant density. 4. Stolon growth up to 80 days after transplaning was relatively slow, but from 80 daysonwards, the growth quickened to range from 1.9 m/clone at 40D to 0.6m/clone at 200Din 200 days after transplanting, these followed by the stolon node produced. 5. Plant density did not affect stolon weight/clone and root weight/clone until 80 daysafter transplanting. 6. DM weight of root was heavier in the early period of growth than that of stolon, butthis trend was reversed in the late period of growth : DM weight of stolon was much higherthan that of root.EXPERIMENT Ill. Vegetative growth of Zoysia japonica and Zoysia matrella as affected by nitrogen and clipping height. 1. When no nitrogen was applied to Zoysia japonica, leaf blade which appeared during theAugust-early September period remained green for a perid of about 10 weeks and even leavesemerged in rate September lived for 42 days. However, leaf longevity did not exceed 8 weeks asnitrogen was applied. In contrast the leaf longevity of Zoysia matrella which emerged during the mid August-earlySeptember period was 11 weeks and, under the nitrogen applied, 9 weeks, indicating that thelife-spen of individual leaf of Zoysia matrella may be longer than that of Zoysia japorica. Clipping height had no effect on the leaf longevity in both grasses. 2. During the July-August period, tiller number, green leaf number and DM weightof Zoysia japonica were increased significantly with fertilizer nitrogen, but were not with twolevel of clipping height. This trend was reversed after late September ; no effect of nitrogen wasappeared. Instead, lax clipping increased tiller number, green leaf number and DM weight. Greenleaves stimulated by lax clipping resulted in the occurrance of more dead leaves in late October. 3. Among the stolons outgrown until early September, the primary stolon was not influencedby nitrogen and clipping treatments to produce only 2-3 stolons. However, 1st branch stoIon asaffected by nitrogen increased significantly, so most of stolons which occurred consisted of 1st branch stolons. 4. Until early September, stolon length obtained at nil nitrogen level was chiefly caused bythe primary stolons. By applying nitrogen, the primary stolons of Zoysia japonica waslonger than 1st branch stolons when severe clipping was involved and in turn, shorter than 1stbranch stolons when lax clipping was concerned. In Zoysia matrella, 1st branch stolons were muchlonger than the primary stolon when turf was clipped severely but in conditions of lax clippingthere was little difference in length between primary and 1st branch stolons. 5. Stolon nodes of both Zoysia japonica and Z. matrella were positively influenced by nit rogen, but no particular increase by imposing clipping height treatment was marked in Zoysiamatrella. Although the stolon of Zoysia japonica grew until late October, the growthstimulated by nitrogen was not so remarkable as to exceed that by nil N.

스마트폰이 널리 보급되고 현대인들의 생활 속에 깊이 자리 잡으면서, 스마트폰에서 수집된 다종 데이터를 바탕으로 사용자 개인의 행동을 인식하고자 하는 연구가 활발히 진행되고 있다. 그러나 타인과의 상호작용 행동 인식에 대한 연구는 아직까지 상대적으로 미진하였다. 기존 상호작용 행동 인식 연구에서는 오디오, 블루투스, 와이파이 등의 데이터를 사용하였으나, 이들은 사용자 사생활 침해 가능성이 높으며 단시간 내에 충분한 양의 데이터를 수집하기 어렵다는 한계가 있다. 반면 가속도, 자기장, 자이로스코프 등의 물리 센서의 경우 사생활 침해 가능성이 낮으며 단시간 내에 충분한 양의 데이터를 수집할 수 있다. 본 연구에서는 이러한 점에 주목하여, 스마트폰 상의 다종 물리 센서 데이터만을 활용, 딥러닝 모델에 기반을 둔 사용자의 동행 상태 인식 방법론을 제안한다. 사용자의 동행 여부 및 대화 여부를 분류하는 동행 상태 분류 모델은 컨볼루션 신경망과 장단기 기억 순환 신경망이 혼합된 구조를 지닌다. 먼저 스마트폰의 다종 물리 센서에서 수집한 데이터에 존재하는 타임 스태프의 차이를 상쇄하고, 정규화를 수행하여 시간에 따른 시퀀스 데이터 형태로 변환함으로써 동행 상태분류 모델의 입력 데이터를 생성한다. 이는 컨볼루션 신경망에 입력되며, 데이터의 시간적 국부 의존성이 반영된 요인 지도를 출력한다. 장단기 기억 순환 신경망은 요인 지도를 입력받아 시간에 따른 순차적 연관 관계를 학습하며, 동행 상태 분류를 위한 요인을 추출하고 소프트맥스 분류기에서 이에 기반한 최종적인 분류를 수행한다. 자체 제작한 스마트폰 애플리케이션을 배포하여 실험 데이터를 수집하였으며, 이를 활용하여 제안한 방법론을 평가하였다. 최적의 파라미터를 설정하여 동행 상태 분류 모델을 학습하고 평가한 결과, 동행 여부와 대화 여부를 각각 98.74%, 98.83%의 높은 정확도로 분류하였다.

For the flexible and rational distribution of limited existing health resources based on measurements of individual risk, the socalled Risk Approach is being proposed by the World Health Organization as a managerial tool in maternal and child health care program. This approach, in principle, puts us under the necessity of developing a technique by which we will be able to measure the degree of risk or to discriminate the future outcomes of pregnancy on the basis of prior information obtainable at prenatal care delivery settings. Numerous recent studies have focussed on the identification of relevant risk factors as the Prior infer mation and on defining the adverse outcomes of pregnancy to be dicriminated, and also have tried on how to develope scoring system of risk factors for the quantitative assessment of the factors as the determinant of pregnancy outcomes. Once the scoring system is established the technique of classifying the patients into with normal and with adverse outcomes will be easily de veloped. The scoring system should be developed to meet the following four basic requirements. 1) Easy to construct 2) Easy to use 3) To be theoretically sound 4) To be valid In searching for a feasible methodology which will meet these requirements, the author has attempted to apply the“Likelihood Method”, one of the well known principles in statistical analysis, to develop such scoring system according to the process as follows. Step 1. Classify the patients into four groups: Group $A_1$: With adverse outcomes on fetal (neonatal) side only. Group $A_2$: With adverse outcomes on maternal side only. Group $A_3$: With adverse outcome on both maternal and fetal (neonatal) sides. Group B: With normal outcomes. Step 2. Construct the marginal tabulation on the distribution of risk factors for each group. Step 3. For the calculation of risk score, take logarithmic transformation of relative proport-ions of the distribution and round them off to integers. Step 4. Test the validity of the score chart. h total of 2, 282 maternity records registered during the period of January 1, 1982-December 31, 1982 at Ewha Womans University Hospital were used for this study and the“Questionnaire for Maternity Record for Prenatal and Intrapartum High Risk Screening”developed by the Korean Institute for Population and Health was used to rearrange the information on the records into an easy analytic form. The findings of the study are summarized as follows. 1) The risk score chart constructed on the basis of“Likelihood Method”ispresented in Table 4 in the main text. 2) From the analysis of the risk score chart it was observed that a total of 24 risk factors could be identified as having significant predicting power for the discrimination of pregnancy outcomes into four groups as defined above. They are: (1) age (2) marital status (3) age at first pregnancy (4) medical insurance (5) number of pregnancies (6) history of Cesarean sections (7). number of living child (8) history of premature infants (9) history of over weighted new born (10) history of congenital anomalies (11) history of multiple pregnancies (12) history of abnormal presentation (13) history of obstetric abnormalities (14) past illness (15) hemoglobin level (16) blood pressure (17) heart status (18) general appearance (19) edema status (20) result of abdominal examination (21) cervix status (22) pelvis status (23) chief complaints (24) Reasons for examination 3) The validity of the score chart turned out to be as follows: a) Sensitivity: Group $A_1$: 0.75 Group $A_2$: 0.78 Group $A_3$: 0.92 All combined : 0.85 b) Specificity : 0.68 4) The diagnosabilities of the“score chart”for a set of hypothetical prevalence of adverse outcomes were calculated as follows (the sensitivity“for all combined”was used). Hypothetidal Prevalence : 5％ 10％ 20％ 30％ 40％ 50％ 60％ Diagnosability : 12% 23% 40% 53% 64% 75% 80%.

급성심장사는 돌연 예기치 못한 심장질환에 의해 갑자기 사망하는 것으로, 법의부검 실시 전 초기 변사현장에서 외피 검시 과정 중 육안적으로 법의학적 사인 추정을 위한 명확한 소견 관찰이 어려운 점으로 인해 법의부검에서 심근 조직의 현미경적 변화 관찰을 통한 진단이 제안되고 있다. 그러나 검사시간, 비용, 편의성 등 변사사건 현장 외표 검시를 통한 사인추정 실무현장에 적용하는데 문제점을 드러내고 있다. 이에 본 연구에서는 임상 병원 진단검사의학에서 급성심근경색 환자의 진단 검사에 이용하는 심장표지물질 간이 검사 키트를 이용하여 사후 혈액에서 심장표지물질 myoglobin, CK-MB, cTn I를 측정하는 간이 검사가 내인성급사인 급성심장사를 사후 진단하는데 유용하게 이용될 수 있는지를 알아보고자 하였다. 외피 검시 및 간이검사 결과 비외상성 급성심장사로 추정되는 실험군 30예를 법의 부검 결과와 비교한 결과 23예(76.7%)에서 양성, 대조군 10예 중 뇌혈관질환 추정 4예 모두 음성, 알코올 및 약물 중독 1예, 산소결핍 질식사 1예에서 양성을 보였다. 심장표지물질 간이 검사의 민감도와 특이도는 각각 76.7%, 80.0%의 유의한 결과를 보여 변사사건 현장에서 변시체의 과거병력, 현장상황 및 사후시간 등을 종합적으로 고려하여 사후 급성심장사의 의심, 추정 진단에 보조적 방법의 하나로 유용하게 이용될 수 있을 것으로 사료된다. 향후 심장표지물질(myoglobin, CK-MB, cTn I)의 개별물질 특성에 의한 혈액 내 최초 발현 및 소멸시간, 시간 경과에 따른 농도 차이 등에 대한 선행연구 결과를 기초로 사망원인 규명 등 사건 해결에 필요한 사후경과시간 추정을 위한 사후 시간대 별 심장표지물질 농도에 대한 추가적인 연구가 계속 되어야 할 것이다.
