Nursing of today has as one of its objectives the solving of problems related to human needs arising from the demands of a rapidly changing society. This nursing objective, I believe, can he attained by the appropriate application of scientific principles in the giving of comprehensive nursing care. Comprehensive nursing care may be defined as nursing care which meets all of the patient's needs. the needs of patients are said to fall into five broad categories: physical needs, psychological needs, environmental needs, socio-economic needs, and teaching needs. Most people who become ill have adjustment problems related to their new situation. Because patient teaching is one of the most important functions of professional nursing, the success of this teaching may be used as a gauge for evaluating comprehensive nursing care. This represents a challenge foe the future. A questionnaire consisting of 67 items was distributed to 200 professional nurses working ill direct patient care at Yonsei University Medical Center in Seoul, Korea. 160 (80,0%) nurses of the total sample returned completed questionnaires 81 (50.6%) nurses were graduates of 3 fear diploma courser 79 (49.4%) nurses were graduates of 4 year collegiate nursing schools in Korea 141 (88,1%) nurses had under 5 years of clinical experience in a medical center, while 19 (11.9%) nurses had more than 5years of clinical experience. Three hypotheses were tested: 1. “Nurses had high levels of concept and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of the T-test. Conclusions of this study are as follow: Before attempting the explanation, of the results, the questionnaire will he explained. The questionnaire contained 67 questions divided into 9 sections. These sections were: concept, content, time, prior preparation, method, purpose, condition, evaluation, and recommendations for patient teaching. 1. The nurse's concept of patient teaching: Most of the nurses had high levels of concepts and knowledge toward patient teaching. Though nursing service was task-centered at the turn of the century, the emphasis today is put on patient-centered nursing. But we find some of the nurses (39.4%) still are task-centered. After, patient teaching, only a few of the nurses (14.4%) checked this as “normal teaching.”It seems therefore that patient teaching is often done unconsciously. Accordingly it would he desirable to have correct concepts and knowledge of teaching taught in schools of nursing. 2. Contents of patient teaching: Most nurses (97.5%) had good information about content of patient teaching. They teach their patients during admission about their diseases, tests, treatments, and before discharge give nurses instruction about simple nursing care, personal hygiene, special diets, rest and sleep, elimination etc. 3. Time of patient teaching: Teaching can be accomplished even if there is no time set aside specifically for it. -a large part of the nurse's teaching can be done while she is giving nursing care. If she believes she has to wait for time free from other activities, she may miss many teaching opportunities. But generally proper time for patient teaching is in the midmorning or midafternoon since one and a half or two hours required. Nurses meet their patients in all stages of health: often tile patient is in a condition in which learning is impossible-pain, mental confusion, debilitation, loss of sensory perception, fear and anxiety-any of these conditions may preclude the possibility of successful teaching. 4. Prior preparation for patient teaching: The teaching aids, nurses use are charts (53.1%), periodicals (23.8%), and books (7.0%) Some of the respondents (28.1%) reported that they had had good preparation for the teaching which they were doing, others (27.5%) reported adequate preparation, and others (43.8%) reported that their preparation for teaching was inadequate. If nurses have advance preparation for normal teaching and are aware of their objectives in teaching patients, they can do effective teaching. 5. Method of patient teaching: The methods of individual patient teaching, the nurses in this study used, were conversation (55.6%) and individual discussion (19.2%) . And the methods of group patient teaching they used were demonstration (42.3%) and lecture (26.2%) They should also he prepared to use pamphlet and simple audio-visual aids for their teaching. 6. Purposes of patient teaching: The purposes of patient teaching is to help the patient recover completely, but the majority of the respondents (40.6%) don't know this. So it is necessary for them to understand correctly the purpose of patient teaching and nursing care. 7. Condition of patient teaching: The majority of respondents (75.0%) reported there were some troubles in teaching uncooperative patients. It would seem that the nurse's leaching would be improved if, in her preparation, she was given a better understanding of the patient and communication skills. The majority of respondents in the total group, felt teaching is their responsibility and they should teach their patient's family as well as the patient. The place for teaching is most often at the patient's bedside (95.6%) but the conference room (3.1%) is also used. It is important that privacy be provided in learning situations with involve personal matters. 8. Evaluation of patient teaching: The majority of respondents (76.3%,) felt leaching is a highly systematic and organized function requiring special preparation in a college or university, they have the idea that teaching is a continuous and ever-present activity of all people throughout their lives. The suggestion mentioned the most frequently for improving preparation was a course in patient teaching included in the basic nursing program. 9. Recommendations: 1) It is recommended, that in clinical nursing, patient teaching be emphasized. 2) It is recommended, that insertive education the concepts and purposes of patient teaching he renewed for all nurses. In addition to this new knowledge, methods and materials which can be applied to patient teaching should be given also. 3) It is recommended, in group patient teaching, we try to embark on team teaching.

本研究的焦点是品牌的拟人化. 品牌拟人化被定义为将品牌看作是人类. 具体来说, 本研究的目标是理解如何将品牌拟人化的方法. 通过分析消费者对食品包装上的故事的阅读, 我们试图展示行销者和消费者如何将一系列品牌拟人化并创造意义. 我们的研究问题是一个品牌对不同的消费者具有多个或单一意义, 联想, 个性的可能性. 我们首先强调了本研究在理论和实践方面的重要性, 解释了为什么我们关注作为品牌意义传递工具的包装. 然后我们阐述了我们量性研究方法, 讨论了结果. 最后总结了管理方面的启示和对未来研究的建议. 本研究先让消费者直接阅读品牌意义传递的工具然后让这些消费者口头自由表达他们所感受到的意义. 具体来说, 为了获得有关感知意义的数据, 我们要求参与者去阅读选择的品牌食品包装上的非营养的故事. 包装在消费者研究方面还没有得到足够的关注(Hine, 1995). 直到现在, 研究还是仅关注包装的实用功能并形成了探索营养信息的影响的研究主体. (例如Lourei ro, McCluskey and Mittelhammer, 2002; Mazis and Raymond, 1997; Nayga, Lipinski and Savur, 1998; Wansik, 2003). 一个例外是最近的研究, 将注意力转向非营养信息的包装说明, 并视其为文化产品和将品牌神话的工具(Kniazeva and Belk, 2007). 下一步就是探索这些神话活动如何影响品牌个性感知以及这些感知如何与消费者相关. 这些都是本研究所要强调的. 我们用深度访谈来帮助消除量性研究的局限性. 我们的便利样本的构成具有人口统计和消费心态学的多样化以达到获得消费者对包装故事的不同的感知. 我们的参与者是美国的中产居民, 并没有表现出Thompson(2004)所描述的 "文化创造者" 的极端生活方式. 九名参与者被采访关于他们食品消费偏好和行为的问题. 他们被要求看看12个展示的食品产品包装并阅读包装上的文字信息. 之后, 我们继续进行关注消费者对阅读材料的解释的问题. (Scott and Batra, 2003). 平均来看, 每个参与者感知4-5个包装. 我们的深度访谈是一对一的并长达半个小时. 采访内容被录音下来并转录, 最后有140页的文字. 产品赖在位于美国西海岸的当地食品杂货店, 这些产品代表了食品产品类别的基本范围, 包括零食, 罐装食品, 麦片, 婴儿食品和茶. 我们使用Strauss和Corbin (1998)提出的发展扎根理论的步骤来分析数据. 结果表明, 我们的研究不支持先前的研究所假设的一个品牌/一个个性的概念. 因此我们展示了在消费者看来多个品牌个性可以在同一品牌身上很好的共存, 尽管行销者试图创造更多单一的品牌个性. 我们延伸了Fournier's (1998) 的假设, 某人的人生计划可以形成与品牌关系的强度和本质. 我们发现这些人生计划也影响感知的品牌拟人化和意义. Fournier提出了把消费者人生主题(Mick和Buhl, 1992)和拟人化产品的相关作用联系在一起的概念框架. 我们发现消费者人生计划形成了把品牌拟人化和品牌与消费者现有的关注相关联的方式. 我们通过参与者发现了两种品牌拟人化的方法. 第一种, 品牌个性通过感知的人口统计, 消费心态学和社会个性所创造. 第二, 第二, 在我们的研究还涉及到品牌的消费者所存在的问题与消费者的个性被混合, 以连接到他们(品牌为朋友, 家庭成员, 隔壁邻居)或远离自己的品牌个性和疏远他们(品牌作为二手车推销员, "一群高管".) 通过关注食品产品包装, 我们阐明了非常具体的, 被广泛使用, 但很少深入研究的营销传播工具: 品牌故事. 近期的研究已经视包装为神话制造者. 对行销者来说要创作出和产品及消费它们的消费者相连的文字故事的挑战越来越大, 并建议 "为创造需求的消费者神话的构成材料的多样化是后现代消费者可论证的需求"(Kniazeva和Belk, 2007). 作为叙述故事的的工具, 食品包装可以食品包装可以用理性和感性的方式, 为消费者提供无论是 "讲座" 或 "戏剧"(Randazzo, 2006), 神话(Kniazeva and Belk, 2007; Holt, 2004; Thompson, 2004), 或意义(McCracken, 2005) 作为他们拟人化产品的构成材料. 孕育工艺品牌个性掌握在作家/营销人员手中, 在读者/消费者心目中. 这些消费者会赋予品牌有意义的脸谱.

매매시점결정은 금융시장에서 초과수익을 얻기 위해 사용되는 투자전략이다. 일반적으로, 매매시점 결정은 거래를 통한 초과수익을 얻기 위해 언제 매매할 것인지를 결정하는 것을 의미한다. 몇몇 연구자들은 러프집합분석이 매매시점결정에 적합한 도구라고 주장하였는데, 그 이유는 이 분석방법이 통제함수를 이용하여 시장의 패턴이 불확실할 때에는 거래를 위한 신호를 생성하지 않는다는 점 때문이었다. 러프집합은 분석을 위해 범주형 데이터만을 이용하므로, 분석에 사용되는 데이터는 연속형의 수치값을 이산화하여야 한다. 이산화란 연속형 수치값의 범주화 구간을 결정하기 위한 적절한 "경계값"을 찾는 것이다. 각각의 구간 내에서의 모든 값은 같은 값으로 변환된다. 일반적으로, 러프집합 분석에서의 데이터 이산화 방법은 등분위 이산화, 전문가 지식에 의한 이산화, 최소 엔트로피 기준 이산화, Na$\ddot{i}$ve and Boolean reasoning 이산화 등의 네 가지로 구분된다. 등분위 이산화는 구간의 수를 고정하고 각 변수의 히스토그램을 확인한 후, 각각의 구간에 같은 숫자의 표본이 배정되도록 경계값을 결정한다. 전문가 지식에 의한 이산화는 전문가와의 인터뷰 또는 선행연구 조사를 통해 얻어진 해당 분야 전문가의 지식에 따라 경계값을 정한다. 최소 엔트로피 기준 이산화는 각 범주의 엔트로피 측정값이 최적화 되도록 각 변수의 값을 재귀분할 하는 방식으로 알고리즘을 진행한다. Na$\ddot{i}$ve and Boolean reasoning 이산화는 Na$\ddot{i}$ve scaling 후에 그로 인해 분할된 범주값을 Boolean reasoning 방법으로 종속변수 값에 대해 최적화된 이산화 경계값을 구하는 방법이다. 비록 러프집합분석이 매매시점결정에 유망할 것으로 판단되지만, 러프집합분석을 이용한 거래를 통한 성과에 미치는 여러 이산화 방법의 효과에 대한 연구는 거의 이루어지지 않았다. 본 연구에서는 러프집합분석을 이용한 주식시장 매매시점결정 모형을 구성함에 있어서 다양한 이산화 방법론을 비교할 것이다. 연구에 사용된 데이터는 1996년 5월부터 1998년 10월까지의 KOSPI 200데이터이다. KOSPI 200은 한국 주식시장에서 최초의 파생상품인 KOSPI 200 선물의 기저 지수이다. KOSPI 200은 제조업, 건설업, 통신업, 전기와 가스업, 유통과 서비스업, 금융업 등에서 유동성과 해당 산업 내의 위상 등을 기준으로 선택된 200개 주식으로 구성된 시장가치 가중지수이다. 표본의 총 개수는 660거래일이다. 또한, 본 연구에서는 유명한 기술적 지표를 독립변수로 사용한다. 실험 결과, 학습용 표본에서는 Na$\ddot{i}$ve and Boolean reasoning 이산화 방법이 가장 수익성이 높았으나, 검증용 표본에서는 전문가 지식에 의한 이산화가 가장 수익성이 높은 방법이었다. 또한, 전문가 지식에 의한 이산화가 학습용과 검증용 데이터 모두에서 안정적인 성과를 나타내었다. 본 연구에서는 러프집합분석과 의사결정 나무분석의 비교도 수행하였으며, 의사결정나무분석은 C4.5를 이용하였다. 실험결과, 전문가 지식에 의한 이산화를 이용한 러프집합분석이 C4.5보다 수익성이 높은 매매규칙을 생성하는 것으로 나타났다.

This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. The specific objectives were: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i)FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the inter-birth interval and/or open interval, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. Study design; The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum 'package' program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and 'before and after' surveys were conducted to measure the change. Service input; This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. Method of evaluation; a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed; b. Nevertheless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the 'integration process' itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltrurture, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable: Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. Summary of Findings; A) Program effects and impact 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 75% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) at delivery care(45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) Effects on Interactive Linkage 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in caring for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, $85{\sim}90%$ of the services provided by the health workers were other than FP/MCH, mainly for immunizations such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs.31%) and for more combined care (45% vs.23%). C) Organization factors (admistrative integrative issues) 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following ; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub·center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwive's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea); 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through family planning practice. 2) Goal consensus in FP/MCH shouBd be made among the health workers It administrators, especially to emphasize the need of care of 'wanted' child. But there is a long way to go to realize the 'real' integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (in) there should be a health sub·center director who can provide leadership training for managing the integrated program. There is a need for 'organizational support', if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the managment of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Worker, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

여포와 난포의 성숙, 배란과 착상, 임신의 유지와 태아의 성장 발달, 분만 및 유선발육과 비유 등 일련의 생식현상에서 있어서 성선자극호르몬과 스테로이드 호르몬의 작용이 중추적인 역할을 한다는 사실은 오래 전부터 알려져왔다. 그러나 이러한 일련의 현상에 고전적인 호르몬 외에도 다수의 성장인자가 관여되고 있음이 최근의 연구 결과 밝혀지고 있다. 생식기관에서 성장인자들은 대부분 autocrine/paracrine mode로 작용하여, 성선자극호르몬과 스테로이드 호르몬의 작용을 매개하거나 이들 호르몬 등과 교호적인 작용(synergy)을 한다. 생식기관 내 insulin-like growth factor(IGF) system은 최근 가장 활발히 연구된 분야 중의 하나로 생식현상의 전반에 걸쳐 중요한 역할을 하고 있음이 밝혀졌다. 본 지면에서는 IGF system에 관한 개괄적인 정보를 소개하고 현재까지 보고된 intrauterine IGF system에 관한 연구를 요약하고자 한다. IGF family는 IGF-I과 IGF-II ligands, 두종류의 IGF receptors(수용체), 그리고 지금까지 발견된 6종류의 IGF-binding proteins(IGFBPs)로 이루어져 있다. IGF-I과 IGF-II는 proinsulin과 상동한 구조를 가진 peptide로서 포도당과 아미노산 운반을 자극하는 등 insulin과 유사한 작용을 한다. 이 외에도 IGFs는 세포분열촉진제(mitogens)로서 여러 형태의 세포에 걸쳐 세포증식을 자극하고, 세포의 분화(differentiation)과 세포기능의 발현에 관여한다. IGFs는 간과 주로 messenchymal cells에서 발현되어 endocrine mode는 물론 autocrine/paracrine mode로 거의 모든 조직에 작용한다. IGF 수용체는 두종류가 알려져 있는데 type I IGF receptor는 tyrosine kinase로서 IGF-I과 IGF-II에 공히 high-affinity를 나타내고, 상기한 대부분의 IGFs의 작용을 매개한다. Type II IGF receptor 혹은 IGF-II/mannose-6-phosphate receptor는 두개의 서로 다른 binding sites를 가지고 있는데 IGF-II binding site는 IGF-II에만 high-affinity를 나타낸다. Type II IGF receptor의 주요 역할은 IGF-II를 lysosomal targeting하여 ligand를 파괴하는데 있다. 체액 속의 IGFs는 대부분 IGFBP에 결합되어 있다. IGFBPs는 IGF의 저장/운반체 혹은 IGF 작용을 조절하는 역할을 하는 것으로 알려져 있으나 개개 IGFBP의 역할에 대해서는 지극히 제한된 정보만이 알려져 있다. IGFBPs의 IGF ligands에의 affinity는 IGF receptors의 IGFs에의 affinity보다 크기 때문에 대부분의 in vitro 상황 하에서 IGFBPs는 IGF 작용을 억제한다. IGFBP에 결합되어 있는 IGF가 어떤 기작에 의해 IGFBP로부터 분리되어 IGF receptor에 도달하는지는 알려지지 않고 있으나, 혈액과 조직액에 들어있는 불특정 IGFBP protease activity는 IGF의 방출과정에서 일역을 하는 것으로 믿어지고 있다. 최근 연구보고에 의하면 특정 in vitro 상황 하에서 IGFBP-1, -3, -5 등은 IGF와 무관한 작용도 있다는 증빙이 있어 IGF system의 또 다른 차원을 예고하고 있다. IGF family members의 mRNAs & proteins는 영장류, 설치류 및 가축의 자궁조직과 수태물(conceptus)에서 발현되어 자궁과 태아의 성장 발달에 중요한 역할을 한다. 자궁조직의 IGF system의 발현은 성선호르몬, 국소 생리조절인자 등에 의해 발현시기와 장소의 특이성이 결정되며, 발현된 IGFs와 IGFBPs는 autocrine/paracrine mode로 자궁조직에 작용하기도 하고, 자궁강에 분비되어 수태물의 성장 발달에 관여한다. 착상을 전후하여 수태물에서도 IGF system이 발현되는데 개개 IGF family member의 발현 시기는 모체로부터 유래된 mRNA의 유무, 수태물 자체의 genetic programming, 모체와의 상호작용 등에 의해 결정되고, IGFs의 작용 부위 역시 시간(생리적 상태)과 장소의 특이성이 있다. 이와같이 conceptus IGF system의 발현이 시간적, 공간적으로 조절되고있다는 사실은 IGFs가 수태물의 성장 발달에 일역을 한다는 가설을 간접적으로 지지해 준다. 자궁조직과 수태물에서 발현된 IGFs는 세포의 증식과 분화, 포도당과 아미노산의 운반과 단백질합성, placental lactogen과 prolactin 등과 같은 유선자극호르몬의 생성을 자극하고 스테로이드 호르몬의 합성에도 관여한다. 태아의 성장 발달에 있어서 IGFs의 역할은 embryo의 IGF-I, IGF-II, 혹은 IGF receptor gene을 homologous recombination technique에 의해 파괴(gene targeting)하여을 때의 결과로써 입증되었다. 생쥐의 IGF and/or IGF-II gene 혹은 IGF receptor gene을 파괴했을 때 출생 전후 모두 성장 발달이 지연되며 출생시 무게는 정상치의 30-60% 수준에 머물고, 특히 type I IGF receptor gene 혹은 IGF-I과 IGF-II genes를 모두 파괴했을 경우에는 출생 후 곧 치사한다. 자궁 내의 IGFBPs는 IGF ligands를 자궁 내에 제한시키거나 IGFs의 receptor binding을 억제하는 negative regulators 역할을 하는 것으로 믿어지고 있다. 그러나 영장류의 자궁에서 IGFBP-I과 같은 특정 IGFBP는 IGFs보다 월등히 많은 양이 발현 분비되고 있는 것으로 추산되고 있으며, 또한 이 단백질은 모체탈락막세포에서 분비되는 주요 단백질 중의 하나라는 점을 감안할 때 IGFBP-I이 IGF과 무관한 작용이 있을 가능성도 배제할 수 없다. 따라서 IGFBPs의 역할 규명은 IGF system을 이해하는데 중요한 부분을 차지하고 있어 향후 이 분야의 연구에 많은 기대와 촛점이 모여지고 있다.
