  • General drug prices involve three stages: shipment stage, wholesaler stage and retail stage. Policies on drug price differ from country to country. Shipment stage prices are tightly regulated in countries like France and Netherlands. They are free in only a minority of advanced countries, even if these include some major players such as the US, Germany and, in a very limited sense, Japan. The situation in the UK is very complex with a semi-free system, where drug companies are free to set their own prices but cannot exceed a predetermined profit ceiling. Mark-up at both wholesaler and retail stages is formally admitted in most countries observed. Apart from the general drug prices, reimbursement price of insured drugs has been major policy concerns. Most countries reviewed in this study has exerted some control over reimbursement prices, but differ both in the way how and in the extent to which prices are admitted or fixed. Price fixing has been used in France and Japan. Some countries have transformed their system over time, particularly to move to reference pricing in the last decade. This mechanism has empowered the customer, and improved price competition on the market. Referring to the drug price policies in the advanced countries, this study makes some suggestions for the redirection of Korean price policy for reimbursement drug in health insurance as follows: to match appropriate policy tools to each policy goal; to maximize market mechanism through effective reimbursement price fixing which admits mark-ups in wholesaler and retail prices; to introduce reference pricing system in order to redirect patient's demand with a financial incentive to choose the best-priced drugs and to save the finance of health insurance; and to strengthen surveillance and monitoring mechanism in the drug market.

  • This paper investigates the idiosyncratic understanding of universal quantifiers such as every, each or all by young children at the ages of 4 to 7, and argues that the phenomenon is explicable in terms of the maturation of both the cognitive system and the linguistic system. Evidence for this dual explanation comes from the fact that the visual input, a picture, plays a key role in determining the children’s conceptual representation, suggesting the need for the central integration of visual and linguistic elements; and from the fact that a quantifier in the linguistic input has an intrinsic property, i.e. a <+focus> feature. I have tried to explain the nature of the cognitive factors in terms of the function of the central system, suggesting a modified form of Smith & Tsimpli’s (1995) version of Fodor’s (1983) modularity hypothesis. Conceptual representations of two kinds are in competition with each other and they are integrated into a neutral LOT (Language of Thought) representation at some point . In the process of this integration, the representations from the visual input predominate over those from the auditory input, though the quantize. (treated as new information provided by the latter) is salient in the final representations. When visual conceptual representations predominate over purely linguistic ones, quantifier spreading errors occur. By contrast, when the relevant grammatical knowledge has developed sufficiently to counteract the conceptual representations, this peculiar behaviour by children should disappear. It is argued that children have to learn two kinds of grammatical fact with regard to universal quantification: (i) they have to learn the status of the quantifier as a functional head of DP so that it has to be positioned inside DP; and (ii) they have to learn the Left-Branch Condition which specifies that movement of an element in the left-branch position is possible only by pied-piping the entire phrase.

  • The position effects on the abortion of flowers, fruits, and ovules were examined in relation to the resource limitation hypothesis using a temperate legume species, Vicia cracca. Fifty plants were randomly sampled from a natural population located at the Belmont Conservation Site in Belmont, MA, USA. Due to indeterminant growth and acropetal flowering of this species, the position of flower or fruit on the plant was able to be coded by the combination of architectural levels such as plant half (lower and upper half) and inflorescence half (lower and upper half) within each plant half. Overall, only 17.3% of the flowers on an inflorescence began to develop into fruits, while overall 36.0% of the fruits initiated failed to mature. Consequently, 11.5% of the flowers successfully matured into fruits. The mean flower number per inflorescence differed significantly among plants as well as between plant halves. Although the probability of fruit initiation was higher in the lower halves of both plant and inflorescence than in the upper halves of the latter, fruit abortion rate differed significantly only between plant halves. The overall mean seed set was 33.6%, implying that about two out of six ovules in a fruit matured into seeds. The seed set was independent of both plant identity and architectural level unlike other reproductive characters examined. When the ovule developmental stage was examined on data pooled over all fruits, the proportion of ovules in varying developmental stages decreased in order of early abortion, seed maturation, late abortion, and seed predation (48.4, 34.9, 12.2, and 4.5%, respectively). A within-fruit ovule position was also used as a class variable for the analysis of position effects on ovule development. All architectural levels considered exerted singificant influence over the ovule development. In particular, ovule development was strongly affected by the within-fruit ovule position. Ovules in both extreme ends within a fruit tended to abort early, while those in the middle position were more likely to mature into seeds. The strong position effects detected from the flowering to seed maturation stage were interpreted as an indication of competitive interaction among reproductive characters which are largely constrained by plant architecture.

  • 오늘날 우리나라의 주류문화는 일반주류와 기능성주류로 분류할 수 있는데, 이 연구에서 기능성주류시장이 특용작물 및 과채류 주류시장에서 농작물(곡류)을 원료로 한 발효주류 시장으로 급격하게 변화하고 있는 것을 인식하게 되었다. 현재, 막걸리 수요는 계속 증가하는 반면 기존 막걸리 용기디자인은 소비자의 욕구 및 현 소비시장의 트렌드에 맞지 않는 용기디자인이 난무하고 있는 실정이다. 당장 주류시장에서 다른 상품과 경쟁하려면 막걸리 용기디자인의 개발이 불가피하다. 이에 따른 현재 생산되는 막걸리 용기디자인이 어떠한 종류들이 있으며, 지금까지 어떻게 변화되어 왔고, 얼마나 경쟁력이 갖추고 있는지를 조사 분석하여, 현, 소비자 트렌드에 부합하면서 막걸리라는 주류의 특성을 고려한 기능성과 실용성을 겸비한 용기를 개발하고자 한다. 그러므로 본 연구는 급속한 주류시장의 변화에서 경쟁력을 갖는 디자인적인 형태와 막걸리라는 특성에 맞는 기능적인 형태 구조를 제시하고자 한다.

  • 본 연구의 목적은 우리나라에서 인터넷 중독 정책에서 나타나는 문제점에 대해서 고찰하고, 융합적 담론 구조에 의한 합리적 국가 정책의 전달체계를 모색하는 데 있다. 이를 위해 문헌연구를 통해 신제도론적 입장에서 현황을 분석하고 또 새로운 대안을 모색했다. 현재 우리나라에는 각 부처간 서로 다른 이해관계 때문에 정부 부처간, 그리고 정부, 기업, 시민사회간 다양한 갈등양상이 전개되는 것으로 나타났다. 신제도론 입장에서는 현재의 중앙정부가 주체가 된 정책 시스템을 향후 지방정부로 이전시키는 한편, 정부가 독점한 주도권을 정부, 기업, 시민사회가 함께 공유하여 거버넌스 형태로 운영하는 것이 최선인 것으로 도출되었다. 10개 중앙정부 협의체 형식의 국가시스템이 아니라 주민생활권 단위의 광역지방정부가 지역공동체 내의 기업, 학교, 시민사회 등과 협력하여 정책을 추진하는 것이다. 이 융합 모델은 현재의 부처간 고착화된 경쟁 구조 때문에 발생하는 갈등을 넘어 중독으로 인해 고통받는 주민에게 더 유익한 대안이 될 것이다. 또한 향후 지역공동체 내에서 정신건강 서비스의 전달체계 연구의 단초가 되기를 기대한다.

  • The vegetation structure in the Hoo - Won, Changduk Palace in Seoul was analysed on 10 sites sampled for understanding structure of natural vegetation. The main vegetational survey was conducted during July, 1985 and actual vegetaion and degree of natural vegetaion types were surveyed additionally. The result summarized of this research are as follows. 1) The physical - chemical conditions of soil showed middle class. This might be derived by short succession period from Pine forest to decidious broadleaf forest and artificial impact by human intervention. 2) When considering dominance species by crown story, Quercus aliena was a dominant species over all site and Castanea crenata, Prunus sargentii and Quercus variabilis appeared as a dominant species locally at upper story. Styrax story and Rhododendron mucronulatum, Styrax japonica, Stephanandra incisa and Lespedeza spp. at lower story. 3) The distances kept by trees per crown story are as follows. The mean distances between trees were 4.5-5.5m at upper story, 2.8-3.3m at middle story. On the other hand, the mean distances between dominant species were 6-8m at upper story, 5-9m at middle story. 4) The vegetation in this area was not developed yet into dominant species community according to the similarity analysis. The natural vegetation was dominated by Quercus spp. especially Quercus aliena according to the analysis of species diversity, relative dominance by story and DBH class. On the orther hand, succession to climax stage dominated by shade tolerent species will take a long time due to little appearance of shade tolerence species by previous heavy artificial impacts on understory species. 5) Quercus forest took possesion of 71.3%(27.37ha) of total forest area when considering the actual vegetation and especially Quercus aliena community covered 53.2%(15.21ha). Carpinus laxiflora community, one of the climax species in temperate zone, took possesion of 1.0%(0.3ha) and Pine densiflora was almost disappeared due to species competition. 6) According to the degree of natural vegetation types, the possession of degree of 6-9 was 60.6% and degree of 7-8, substitute vegetation, was 15.5%. The possesion of degree of 9 which consists of over 50 years old trees simliar to natural vegetaion was the highest, 43.1% in this area. Therefore continuous protection in this area of degree of 9 should be recommended.

  • The purpose of this research is to analyze the overall process of the wedding industry - arranging domestic wedding firms and formulating a database related to the business. Simultaneously, with all the data in hand the research attempts to seek flaws within the wedding industry and tries to offer solutions to revitalize the industrial section. Because the list of articles is enormously expansive, for the purpose of basic research, objects have been selected according to the process presented below. Wedding-product firms have been classified within the boundaries of dresses, studios, and makeup firms; distributing channels are mainly focused on wedding planners and related-consulting firms; related departments of universities and wedding organizations are illustrated as well. Due to the unorganized system of this particular field, the research process has been conducted with materials from personal experiences, newspapers, magazines, Internet websites, documents, and interviews with wedding-related firms and organizations, and professors. As a result, over 13 subjects which formulate a market structure of over 30 trillion won. However, due to lack of systemization of the industry, as it expands, numerous problems occur. Excessive competition between wedding-consulting firms and the lack of reliable education for wedding planners, unnecessary external investment and the lack of product research, false Information from the Internet puts the entire industry in a inefficient position. Organizations such as Korea Traditional clothes Industrial Union, Korea Wedding Consulting Association, Korea Martial Industrial Promotion Association(KOMIPA) etc, are made to seek for solutions. For the wedding industry to revitalize, wedding-product firms, wedding planners and consulting firms must maintain an organic relationship every season. They must systemize a proper distribution system, with wedding-product companies enhancing the quality of products, wedding planners organizing wedding plans with responsibility, and consulting firms focusing not only on profits. In order to make high-valued products, wedding-product companies must put their greatest effort in producing talented minds, and universities with related departments must do so as well. In other words, the industrial and educational section of our society must cooperate through a sophisticated system. In addition, related organizations must act to receive governmental support in order to support the industry.

  • 본 연구에서는 종아리 근육에 기능성 의류를 착용한 것이 종아리의 근기능에 어떤 영향을 미치는지 규명하고 기능성 의류가 종아리 근기능 증가에 활용가치가 있는지 검증하고자 하는데 그 목적이 있다. 연구의 대상은 하지에 이상이 없는 B 대학교의 남학생 21명을 대상으로 측정 하였다. 측정방법은 등속성근기능측정기인 CSMI사의 Humac Norm을 이용하여 오른쪽, 왼쪽 종아리에 기능성 의류 착용 전, 후 각속도 30°/sec, 120°/sec로 측정하였다. 피실험자들이 기능성 의류를 착용했을 때와 착용하지 않았을 때를 측정 해본 결과 발목 배측굴곡(Dorsi flexion)에서는 기능성 의류를 착용했을 때와 착용하지 않았을 때 유의한 차이가 나타나지 않았으나, 발목 저측굴곡(Plantar flexion)에서는 기능성 의류를 착용하였을 때 근력, 근파워, 근지구력이 유의하게 증가하는 것으로 나타났다. 따라서 종아리의 기능성 의류 착용이 운동기능 향상에 긍정적 효과가 있으며, 향후 연구에서는 대회를 앞두고 훈련을 하는 선수에게 기능성 의류를 착용한 인원과 착용하지 않은 인원의 근기능 향상정도를 비교해보는 연구를 제시하는 바이다.
