  • 이 연구는 수행평가 장면에서 교사의 평가를 이끈 실천적 지식이 무엇인지를 사례연구를 통해 살펴본 것이다. 교실 수업에서 교사의 교수행위는 자신의 독특한 창작물이며 전문가로서 교사의 모든 역량과 지식이 표출되는 활동이다. 여기서 교사가 어떤 내용의 지식을 어떤 상황인식 하에서 어떤 방식으로 무엇을 이용해서 가르칠 것인가 등의 교사의 판단을 이끄는 지식, 즉 교사가 교실에서 수행하는 행위의 실천을 유도하는 지식을 실천적 지식이라고 할 수 있다. 교사의 수업을 바로 읽는데 교사의 실천적 지식에 대한 이해가 필요할 것이다. 일반적인 교수-학습 활동과 마찬가지로 수업 상황 중에 평가가 이루어지고 학생들의 학습의 증진을 목표로 하는 수행평가 역시 평가 목표 설정, 평가 장면 구성, 평가 도구 개발, 평가 준거 개발, 평정 활동 등 모든 교사의 활동 역시 직전교육, 현장의 교수 경험, 일상에서의 경험, 연수 등을 통해 형성된 암묵적 지식인 실천적 지식의 안내를 받으면서 이루어진다. 이 연구는 고등학교 지리교사의 사례 연구를 통해서 그 교사의 평가를 이끈 실천적 지식의 구조를 이미지, 원리, 규칙의 측면에서 파악해 보았다. 연구의 결과 드러난 교사의 실천적 지식은 교사의 모든 의사결정 과정에서 어떤 방향을 잡아주는 안내자의 역할을 하고 있으며, 이런 관점에서 교사의 평가 행위를 봄으로써 교실에서 벌어지는 과정중심평가가 이루어지는 실제적인 모습을 확인할 수 있었다.

  • The attempts to explain the criterion of art criticism can be divided into three directions. The first is that there is a universal criterion of criticism. The second is that criticism is a subjective impression of each critic. Therefore, there is no universal criterion beyond a subjective impression. The third is that denies both claims. It tries to and the objective criterion which is neither universal nor subjective. In this paper, I will see how John Dewey criticizes the first two theories and holds the third theory. Dewey's denial of the first theory can be seen in his view of the judical criticism. The judical criticism claims that art criticism can be made on the universal criterion, as judical decision can be made on the general rule supposed to be applicable to all cases. But Dewey claims that the judical criticism cannot explain what makes the artist the 'masters'. Defining art as an experience, Dewey claims that art is a process of doing and undergoing, and that art is essentially an interactive activity between men and his environment As environment changes, the experience of the environment also changes. So art should accept the possibility of new experience. But, since the judical criticism advocates of the universal criterion which cannot allow the changeability, Dewey denies it. On the other hand, Dewey's denial of the second theory can be seen in his view of the impressionist criticism. The impressionist criticism claims that criticism is to clarify the impression which is consisted of feeling and imagery the art object evokes. To this claim, Dewey replies that to clarify an impression is to analyze it, and analysis can proceed only by going beyond the impression to the judgement. As we have seen so far, Dewey has denied the judical criticism that there is a universal criterion supposed to be applicable to all criticism. He has also denied the impressionist criticism that there are only subjective responses to the art object, and hence that there is no criterion of criticism at all. For Dewey, these two criticism are based on the same false assumption of the criterion, although their conclusions are different from each other. Both the judical and impressionist criticism failed to realize the difference between the meaning of the criterion as applied in measurement and as used in criticism. Criticizing of these two views of criticism, Dewey claims that there is an objective criterion which is neither universal nor subjective. Art criticism is objective in tv#o senses, i. e., in the first sense that it can be judged by the properties of the art object and in the second sense that it can be verified by the communities of the critics.

  • 국내뿐 아니라 전 세계적으로 환경문제가 이슈화 되면서 저탄소 녹색성장이라는 수식어는 정치, 경제, 사회 등 전 영역에서 자주 사용되고 있다. 저탄소 녹색성장 정책으로 환경에 대한 관심이 증대되고 있으며, 정부는 환경보호와 환경관리를 위해 환경규제강화와 친환경정책을 함께 펴고 있다. 본 연구는 녹색기업과 환경규제위반기업간의 특성차이를 실증분석 하였다. 환경의식, 재무적 능력, 기업의 구조적 특성 및 기술적 특성 등 기업의 특성과 기업의 환경친화성과의 관계를 실증분석 하였다. 가설은 환경관리 담당자들과의 인터뷰와 기존연구를 바탕으로 설정하였으며 분석결과는 다음과 같다. 첫째, 녹색기업과 환경규제위반기업간의 특성관계에서 기존연구의 결과와 달리 환경의식의 대위변수인 지배주주지분율은 유의한 결과를 얻지 못하고 기각되었으나 ISO 14001 인증여부는 유의한 결과를 보이고 있어 환경성과에 영향을 주고 있음을 확인하였다. 둘째 기업의 재무적 능력은 녹색기업과 환경규제위반기업간의 특성에서 유의한 결과를 얻지 못하고 기각되었다. 이는 환경성과와 재무능력은 관련이 없다는 것으로 재무성과가 더 좋은 기업이거나 나쁜 기업일지라도 반드시 환경성과에 영향을 주는 것이 아니라는 것을 시사하고 있다. 셋째, 기업의 구조적 특성은 녹색기업과 환경규제위반기업간의 관계에서 기존연구와 다른 결과를 보여주고 있다. 자본집약도의 지표인 유형자산비중과 수출비중은 기각되었고 종업원비중은 유의한 결과를 얻었지만 기존연구와 반대의 결과로 종업원비중이 높은 기업이 환경규제를 위반한다는 결과를 보이고 있다. 넷째, 기술적인 능력이 환경성과에 영향을 준다는 유의한 결과를 얻었는데 그 결과는 기존연구와 같다는 것을 확인하였다. 즉 연구개발투자비중이 높을수록 환경규제를 준수한다는 것으로 확인되었는데, 이는 녹색기업이 환경규제위반기업보다 연구개발투자를 많이 하고 있으며 환경기술능력을 향상시켜 환경관리를 잘 하고 있음을 확인하였다.

  • The purpose of this study is to explore the family as an interaction system, concentrating on the mutual influences between communication and family development; (1) how Communication patterns affect family relationships, and (2) how relationships among family members affect communication. In order to do this Galvin, Brommel used the following frame work; family is a system in which communication regulates cohesion and adaptability by a flow of message patterns through a defined network of evolving interdependent relationships. A family system consists of members, the relationships among them, the family attributes, the members attributes and an environment in which family functions. Within the framework of common cultural communication patterns, each family has the capacity to develop its own communication code based on the experiences of individual members and the collective family experience. Most of us develop our communication skills within the family context learning both the general cultural language and the specific familial communication code. Communication may be viewed as a symbolic, transactional process as the process of creating and sharing meanings. To say that communication is a process implies a continuous interaction of an indefinite large numbers of variables with a concomitant,. continuous change in the values taken by these variables. Finally the process implies change, Family functions include the primary functions of cohesion and adaptability, and supporting functions of family images, themes, boundaries, and biosocial issues. The primary functions reveal concepts integrated family interaction and supporting function, along with those of cohesion and adaptability, give shape to family life. the characteristics of developed relationships of richness, uniqueness efficiency, substitutability, pacing , openness spontaneity, and evaluation are reflected in the verbal and nonverbal behaviors with which family members negotiated a set of common meanings and develop thier own unique message system. The message system is the major element of communication process and influences both the form and the content of thier relationship and in create and share meanings. Family systems need to provide order and predictability for thier members, specifically focusing on communication rules and the networks by which messages are transmitted. Most rules emerge as a result of multiful interactions. There are basic rules and rules about rules, or metarules. Perceiving the rules of family system is very difficult because often family members don't think about the basic rules, much less the metarules. Breaking the rule may result in the creation of a new set because the system may recalibrate itself to accept more variety of behavior. Families develop communication networks to deal with the general issue. Family adaptability may be seen through the degree of flexibility in forming and reforming networks and networks become a vital part of the decision- making process and relate to the power dynamics operating within the family. Networks also play an integral part in maintaining the roles and rules operating with the family system. Thus networks and rules have mutual influence. The family -of -origin issues influence all aspects of family communication and account for many of the communication patterns, rules and networks and the role of the family -of-origin influences as a primary force for communication on behavior of newly forming systems. Each family system develops its own communication meanings. There is not one right way to communicate within a family but may be indefinitly large change of family life and communication behavior. Study on functional family communication helps to gain a better understanding of dynamics of family communication and ability of a new insight into the family.

  • This article is to analyse the economic efficiency of capital market, which plays a role of resource allocation in terms of financial claims such as stock and bond. It provides various contributions to the welfare theoretical aspects of modern capital market theory. The key feature that distinguishes the theory described here from traditional welfare theory is the presence of uncertainty. Securities has time dimensions and the state and outcome of the future are really uncertain. This problem resulting from this uncertainty can be solved by complete market, but it has a weak power to explain real stock market. Capital Market is faced with the uncertainity because it is a kind of incomplete market. Individuals and firms in capital market made their consumption-investment decision by their own criteria, i. e. the maximization of expected utility form intertemporal consumption and the maximization of the market value of firm. We noted that allocative decisions that had to be made in the economy could be naturally subdivided into two groups. One set of decisions concerned the allocation of first-period resources among consumption $C_i$, investment in risky firms $I_j$, and riskless investment M. The other decisions concern the distribution among individuals of income available in the second period $Y_i(\theta)$. Corresponing to this grouping, the theoretical analysis of efficiency has also been dichotomized. The optimality of the distribution of output in the second period is distributive efficiency" and the optimality of the allocation of first-period resources is 'the efficiency of investment'. We have found in the distributive efficiency that the conditions for attainability is the same as the conditions for market optimality. The necessary and sufficient conditions for attainability or market optimality is that (1) all utility functions are such that -$\frac{{U_i}^'(Y_i)}{{U_i}^"(Y_i)}={\mu}_i+{\lambda}Y_i$-linear risk tolerance function where the coefficients ${\mu}_i$ and $\lambda$ are independent of $Y_i$, and (2) there are homogeneous expectations, i. e. ${\Large f}_i(\theta)={\Large f}(\theta)$ for every i. On the other hand, the efficiency of investment has disagreement about optimal investment level. The investment level for market rule will not generally lead to Pareto-optimal allocation of investment. This suboptimality is caused by (1)the difference of Diamond's decomposable production function and mean-variance valuation model and (2) the selection of exelusive investment or competitive investment. In conclusion, this article has made an analysis of conditions and processes of Pareto-optimal allocation of resources in capital marker and tried to connect with significant issues in modern finance.

  • 서울시 대중교통체계개편에서 요금부과방안은 기본적으로 거리비례제에 근거하고 있다. 거리비례제에서 요금은 일정거리까지의 통행에 따른 기본요금과 수단적 환승에서 발생하는 환승요금, 일정거리 이상의 통행에 따른 할증요금으로 구분하여 부과된다. 본 연구는 거리비례제에 따른 요금부과 시 순차적으로 정렬된 K개의 요금경로를 탐색하는 K요금경로탐색알고리즘을 제안한다. 이를 위해 다수의 대중교통수단이 존재하는 복합교통망에서 링크표지기법을 적용하여 네트워크확장이 요구되지 않도록 하였으며, 동일링크를 통행하는 복수의 통행순단을 각각의 개별링크로 처리되도록 구축하였다. 따라서 본 연구에서 제안하는 K요금경로탐색알고리즘은 수단과 관련된 별도의 표식이 요구되지 않으므로 단일수단 교통망에 확용되는 K경로탐색알고리즘이 직접 적용될 수 있다. 본 연구는 또한 출발지에서 수단을 탑승한 이용자에게 요금이 부과되는 과정을 복합교통망에서 나타내가 위하여 출발지를 기준으로 탐색되는 인접된 두 링크에 대해서 기본요금, 환승요금, 할증요금이 계산되어 합산되는 과정을 수식으로 표현하였다. 이 수식을 K개의 원소를 포함하는 재귀벡터형태(Recursive Vector Formula)로 전화하여 K요금경로탐색을 위한 최적식과 알고리즘을 제안하였다. 간단한 사례연구를 통하여 알고리즘 수행과정을 검증하고 향후에 연구진행방향에 대하여 서술하였다.

  • The objective of this study was to determine potential contributing factors associated with biosecurity level of farrow-to-finish pig farms and to develop a classification tree model to explore how these factors related to each other based on prediction model. To this end, the author analyzed data (n = 193) extracted from a cross-sectional study of 344 farrow-to-finish farms which was conducted between March and September 2014 aimed to explore swine disease status at farm level. Standardized questionnaires with information about basic demographical data and management practices were collected in each farm by on-site visit of trained veterinarians. For the classification of the data sets regarding biosecurity level as a dependent variable and predictor variables, Chi-squared Automatic Interaction Detection (CHAID) algorithm was applied for modeling classification tree. The statistics of misclassification risk was used to evaluate the fitness of the model in terms of prediction results. Categorical multivariate input data (40 variables) was used to construct a classification tree, and the target variable was biosecurity level dichotomized into low versus high. In general, the level of biosecurity was lower in the majority of farms studied, mainly due to the limited implementation of on-farm basic biosecurity measures aimed at controlling the potential introduction and transmission of swine diseases. The CHAID model illustrated the relative importance of significant predictors in explaining the level of biosecurity; maintenance of medical records of treatment and vaccination, use of dedicated clothing to enter the farm, installing fence surrounding the farm perimeter, and periodic monitoring of the herd using written biosecurity plan in place. The misclassification risk estimate of the prediction model was 0.145 with the standard error of 0.025, indicating that 85.5% of the cases could be classified correctly by using the decision rule based on the current tree. Although CHAID approach could provide detailed information and insight about interactions among factors associated with biosecurity level, further evaluation of potential bias intervened in the course of data collection should be included in future studies. In addition, there is still need to validate findings through the external dataset with larger sample size to improve the external validity of the current model.

  • 'Governance' is a subject that is widely discussed these days in the government and the academic world. I think that the new concept, 'governance', is a strategy to develop the democracy of the society in its institutional and functional aspects. When we are going to discuss about governance, public records and their relationships, without understanding the meaning of 'public' in Korea, we cannot expect to discuss the matter precisely. It is said that Korean public service sectors are awash with authoritarianism and unreasonableness, and that they are at the center of seething corruption and bribe scandals. It is the legacy that the regimes adopted in the aftermath of the Japanese colonial rule for 35 years. The colonial legacy included not simply the practice of the Japanese colony, but also people who had collaborated the Japanese. The American military government and Rhee, Sung-Man regime also appointed the same officials to government posts. As was the same case in other areas including economy, press, education, politics, law, etc. In this point of view, "Righting historical wrongs", a controversial issue now in Korea, aims at establishing the right relationships between an individual and the public, and eventually laying the foundation of democracy for future generation, a procedure of achieving good governance. Apparently, Korea has made progress in developing democracy, as well as in reforming the government policy and organization. Many independent commissions are performing the projects instead of the government institutions that mandated to do the job, but has not played their roles. The e-government projects in Korea was launched in 2001 by the former administration. However, the confusion of records-management after the promulgation of the act is the result of the lack of strategy and the inconsistency of the vision. Good record-keeping supports effective, transparent and accountable government. Accountability is a key element of good governance. It is a recognized fact that without information, there is no guidance for decision-making, and accountability. Thus without records, there is no accountability for the decisions of actions. Transparency means that the decisions taken and their enforcement are carried out based on led-out rules and regulations. When both accountability and transparency are non-existent, good governance is bound to fail. Archival institutions have to give an attention to inner-governance because of the new trend of archival practice, namely 'macro-appraisal'. This 'macro-appraisal' is a kind of a functions-based approach. However, macro-appraisal focuses not just on function, but on the three-way interaction of function, structure and citizen, which combined reflect the functioning of the state within civil society, that is to say, its governance. In conclusion, the public and democracy are major challenges in the Korean society. The so-called good governance requires good record management. In this respect, records managers are in the front line of instituting good governance, and achieving better public and democracy for future generation, a procedure of achieving good governance.

  • 이 글의 목적은 미얀마 민간정부의 정치발전 양상을 결손민주주의 개념에서 분석하고, 정치발전을 지체 또는 정체시킨 주체들과 주체들 간의 상관관계를 규명하는 것이다. 나아가 이 글에서는 현재와 같은 정치구도와 행태를 돌파하여 긍정적인 정치발전을 위해 요구되는 과제를 제시하고자 한다. 2016년 민간정부가 출범했으나 권력 행사와 의사결정구조에 있어서 정부의 행동 양식은 군부 권위주의의 행태를 탈피하지 못함으로써 긍정적인 정치발전의 성과를 달성하지 못했다. 정부 차원에서 특정 인물 1인이 모든 권력을 장악하고 각 권력기관에 대한 수평적 책임을 지지 않으므로 위임민주주의와 후견민주주의가 강화된다. 국방과 치안에서 지분을 장악한 군부는 버마족 중심의 배타적 민주주의와 군부가 제정한 비민주적 헌법을 수호하며 비자유적 민주주의를 추구한다. 결손민주주의가 나타나는 근본적인 원인은 장기간 군부통치로 인해 민주적 제도를 운영할 집단의 부재, 민간에 의한 군부통제라는 민간우위의 원칙을 지킬 수 없는 권력구도의 한계로 요약된다. 따라서 미얀마 정치발전의 과제는 군부의 병영 복귀와 권위주의적 질서에 길들여진 민간정부의 권력구도와 정치행태를 민주적으로 전환하는 것이다.
