  • 이 연구의 목적은 학생들의 논증을 인식론적 (사고과정) 및 심리학적 (사고유형) 관점에서 탐색하여 어떠한 사고과정 및 유형으로 교사가 학생들의 논증 형성 능력을 향상시키는지 알아보는 것이다. 35년의 교사경력을 지니고 있는 교사 및 그의 26명 학생의 과학수업 60시간을 관찰하고, 전사하였으며, 전사한 학생들의 논증이 어떻게 표현되는지를 두 개의 도구, 즉 인식론적 및 심리학적 관점으로 분석하였다. 이 연구 참여자인 교사는 학생들의 논증의 질을 향상 시키기 위하여 특별한 목적으로 개발한 명시적인 교수법 "주장-근거 교수법"을 수업 시간에 활용하였다. 논증을 두 개의 다른 관점으로 분석해 본 결과, "보기" 또는 "예"를 이용한 사고과정에서는 "정교성" 사고유형이 가장 빈번하게 사용되었다. 모든 탐구의 시작인 가설을 세우기 위해 학생들은 "귀납" 사고과정으로 "일반화" 사고유형을 통해 탐구의 시작단계인 본인들의 "주장"을 형성하였다. 좀 더 높은 수준의 논증은 다른 지식이나 경험을 통한 개념의 "일관성" 사고 과정을 통해 교사의 도움에 힘입어 학생들이 "설명"을 형성하였다. 이러한 높은 수준의 논증 기회에서 확인된 교사의 역할은 학생들이 스스로 논증을 형성할 수 잇도록 도와주는 조력자, 그리고 학생들의 논증을 평가하는 것이 아닌 좀더 학생들의 사고과정을 확장시켜 주는 정교자 (elaborator), 그리고 학생들의 논증 수준이 높아질 수 있도록 논증을 추적하여 발전시켜주는 멘토로 확인되었다. 논증 본성에 대한 이해를 바탕으로 교사들은 학생들이 과학의 참 의미를 이해 할 수 있도록, 논증 기회를 제공하는 명시적인 교수전략을 개발하는 것이 필수적이라 할 수 있겠다.

  • Nowadays, it is surely the quack which stands as one of the most controversial, problematic. the quack has been a consistent target of contested public protection strategies in the past few centuries in many countries. Recently, complementary and alternative medicine (CAM) is increasingly utilized and accepted by patients and providers throughout the health care system in the world, most accounts attribute this growing acceptability to the shortcomings of conventional medicine, the appeal of CAM's core beliefs, and the growing body of research indicating that CAM actually works. However, the governments of western countries have called for measures to ensure that the public are protected from incompetent and dangerous practitioners. Common to these controversies has been a suggestion to ban, exclude or limit the medical practice of those deemed to be damaging rather than improving the health of individuals as a measure of public protection. This article describes the experiences of western counties' health care system which is moving in a more pluralistic direction. By examining the ways in which regulatory efforts in the countries have come to address what is invariably described as a growing interest in CAM, this study show how the problem of CAM/quackery today is increasingly located in an ethical field of practitioner competency, qualifications, conduct, responsibility and personal professional development, regardless of the form of therapy in question. Many countries developed a series of measures and strategies to contain the acceptance of CAM groups, such as insisting on scientific evidence of safety and efficacy, resisting integration of CAM with conventional medicine and opposing government support for research and education. In a sense, those countries' movements serve to protect not only patients, but the dominant position of medicine and its allied professions, and to maintain existing jurisdictional boundaries within the healthcare system. The popular support for CAM will require that health professional stakeholders continue to address the challenges this poses, and at the same time protect their position at healthcare system. To cope with the quack, professional body, public sector and health authorities should consider the safety of consumers of healthcare and responding to the demands of the community for CAM therapies as well as the claims of the established healthcare professions. Finally, some implications for future health care were suggested.

  • This study was conducted to investigate whether variations in hospital services utilization across small geographic areas in Korea existed, and if so, what factors are responsible for the variation. The claims data of the fiscal year 1992 obtained from the regional health insurance societies were used for the study. Main findings of the research can be summarized as follows: 1 Extremal Quotients (EQ) of hospital expenditure per capita and hospital days per capita were 2.69 and 2.73, and Coefficient of Variation (CV) were 0.14, both, respectively. The EQ and the CV of admission rate were also 2.71, 0.15. The EQ and the CV of expenditure per admission were 1.73, 0.10 and those of hospital days per admission were 1.29, 0.06. All these statistics were statistically significant and this result provides strong evidence for the existence of small area variations. 2. Comparing patterns of variation among areas, the area which showed higher utilization amounts is Chansungp'o. Koje area, whereas the areas which showed lower utilization amounts are Yongju, Changhung, Miryang, Mokp'o, Koch'ang area. 3. Multivariate analytic methods were used to examine factors related to the variation across areas. In terms of the health resource availability variables, beds per capita or physicians per capita were positively associated with all utilization indices. As for the health service market structure variables, the proportion of health care institutions operating for less than f years was positively related to the expenditure per capita, hospital days per capita and expenditure per admission. In addition the proportion of the private health care institutions also had a negative relationship with total utilization amount and admission rate and the proportion of physicians under age 40 was negatively associated with expenditure per capita and expenditure per admission. With regard to the socio-demographic characteristics, proportion of medicaid population was positively related to hospital days per capita, and percentage of paved road was positively related to hospital days per admission. As a conclusion, wide variations existed across small areas in Korea and supply factors were found to be important in explaining the variation.

  • Internally Korean insurance market is that whole life products' growth are becoming slowdown that's why new insurance products have appeared on the market in consideration of consumer's needs recently. Externally domestic insurance market competitions has drifted from insurance industry to whole financial industry since bankasurance started. Life insurance companies should open up a new market to survive from severe competitions. Worksite marketing can be an alternative. An insurer make arrangements with an employer about an insurance terms which an insurer offers in Worksite marketing. Then eligible individuals enroll in the plans at their own discretion and pay 100 percent of the premium for coverage through payroll deductions. An employer doesn't need to pay extra money for additional benefit but can raise employee's loyalty and satisfaction of company through worksite marketing. An employee can be covered at discounted premium rate and less strict underwriting guidelines to an insurer compared to individual insurance. In developed countries specially U.S insurance market, Worksite marketing is getting very popular and growing rapidly due to the advantages. Worksite marketing has both individual insurance characters and group insurance characters. Individual insurance characters are that employees enroll in the plans at their own discretion and pay 100 percent of the premium for coverage. Group insurance characters are that actively at work and participation etc. An insurer have to reflect these two characters on Worksite marketing when an insurance company work out a plan for developing products and underwriting guidelines. When an insurer devise worksite products, one should consider participation level which means percentage of eligible employees participating. Participation is related to anti-selection. As we know underwriting is essential for every kind of insurance, especially underwriting plays major role in worksite marketing. We can see that in the below. Firstly, it has a function in calculation of premium rate. When calculate premium rate for worksite products underwriters have to estimate expected participation level and risk factors. So underwriters and acturies keep in close contact with each other. Secondly, underwriting methods are important. When an insurer underwrite worksite products, there are three kinds of underwriting methods. These are Simplified issue underwriting, Full underwriting and Guaranteed issue underwriting. Simplified issue underwriting typically requires no medical examination, but usually requires supplying satisfactory answers to one or several health and/or lifestyle questions. Full underwriting requires a complete medical history questionnaire that may further require an exam. Guaranteed issue underwriting means that coverage is issued without the employee having to provide evidence of insurability. When insurer set the GI limit are usually based on the type of industry, number of eligible employees, the average amount of coverage and participation level. In addition to insurer should have a clear definition of eligible employee on the insurance provision and application form. It will minimize possibility of trouble claims and anti-selection. An insurer also establish preexisting condition exclusion and special guidelines for late entrants. When an insurer introduce Worksite marketing to Korean insurance market, an insurer has to examine market research to analyze potential market and strategy of sales most of all. Also an insurer should review real situation of the U.S, England and Japanese market etc. There are a lot of new technologies about worksite marketing process that an insurer should learn. When an insurer consider many things which we explained it can be a real alternative.

  • The rotavirus-induced diarrhea of human and animal neonates is a major public health concern worldwide. Until recently, no effective therapy is available to specifically inactivate the rotavirion particles within the gut. Passive immunotherapy by oral administration of chicken egg yolk antibody (IgY) has emerged of late as a fresh alternative strategy to control infectious diseases of the alimentary tract and has been applied in the treatment of diarrhea due to rotavirus infection. The purpose of this concise review is to evaluate evidence on the properties and performance of anti-rotavirus immunoglobulin Y (IgY) for prevention and treatment of rotavirus diarrhea in human and animal neonates. A survey of relevant anti-rotavirus IgY basic studies and clinical trials among neonatal animals (since 1994-2015) and humans (since 1982-2015) have been reviewed and briefly summarized. Our analysis of a number of rotavirus investigations involving animal and human clinical trials revealed that anti-rotavirus IgY significantly reduced the severity of clinical manifestation of diarrhea among IgY-treated subjects relative to a corresponding control or placebo group. The accumulated information as a whole depicts oral IgY to be a safe and efficacious option for treatment of rotavirus diarrhea in neonates. There is however a clear need for more randomized, placebo controlled and double-blind trials with bigger sample size to further solidify and confirm claims of efficacy and safety in controlling diarrhea caused by rotavirus infection especially among human infants with health issues such as low birth weights or compromised immunity in whom it is most needed.

  • Environmental disputes not only possess the special characteristics of collectivity and plural value relativity but it also possesses the unique features of difficulty to prove cause and effect as well as the structural maldistribution of evidence and information. Therefore, the positive resolution of an environmental dispute can be brought about more easily with the Alternative Dispute Resolution (ADR) which can take the form of talks, compromises, as well as arbitration or mediation rather than through a trial process. Such being the case, this paper first looks into the problems and effectiveness of the arbitration system of environmental lawsuits and then takes an even closer look at Korea's environmental dispute arbitration system and finally offer some reform methods. In Korea, the environmental dispute arbitration system was implemented in 1991 and has been executed since then. Although this system does have positive features such as the high rate of coming to an agreement between the involved parties but unfortunately, most of the cases rely on decisions based on right and wrong which cannot but be far away from the intentions of the ADR system. It is heavily centered around claims regarding psychological compensation regarding noise and vibrations and the ratio of the actual amount of compensation is comparatively lower than the requested amount. In addition, with the limits in organization and manpower, it leads to a lack of professionalism as well as the problem of low usage with the low awareness rate. As reform measures against the aforementioned problems, this paper suggests the following. First, in order to activate the arbitration process more fully, it proposes aggressive usage of compulsory arbitration as well as submission to arbitration, while at the same time raising ADR professionals to fill in the missing gaps. Secondly, in order to overcome the problem of concentration of related cases, making representative lawsuits of environmental organizations would be a good idea. It also states that in order to make the compensation amount more realistic, it should go out of the across-the-board decision making process and reach a decision about the compensation amount that takes the individual situation's dispute into consideration. In order to boost the professionalism of the environmental dispute arbitration, it is necessary to reform the organization and manpower such as expanding the number of members of full standing, and increasing the professionalism of the examiners. Also, to increase the usage rate of the ADR system, the paper suggests stationing a civilian consultant regarding environment, or activating the compulsory arbitration which is the premise for public participation on the part of the residents.

  • ERP 시스템의 성공적인 구축을 위해서는 ERP 제품에서 제공하는 기능과 조직이 요구하는 기능 간의 차이에서 발생하는 부적합을 해결하는 것이 매우 중요하다. 그 동안 부적합의 해결방안으로서 커스터마이징을 가능한 자제하고 ERP의 기능에 조직의 업무를 적응시킬 것이 권고되어왔다. 그러나 실제 커스터마이징의 효과를 분석한 연구가 없었으므로 본 연구에서 그 효과를 살펴보고자 한다. 본 연구에서는 전체 적인 커스터마이징의 효과뿐만 아니라 커스터마이징을 유형별로 구분하여 변경 및 추가의 효과를 살펴보았다. 또한 ERP 제품에서 기능을 제공하는데도 커스터마이징을 하였는가, 그리고 커스터마이징한 업무 프로세스에 대해 사전 BPR을 실시하였는가에 따라 커스터마이징의 효과를 살펴보았다. 현장 연구를 통하여 이러한 관계를 살펴본 결과 전체적인 커스터마이징의 정도는 사용자 만족도와 조직의 경쟁우위에 영향을 미치지 않았으며, 유형별로 분류하여 검증한 결과추가의 정도만이 사용자 만족도와 조직의 경쟁우위에 유의적 영향을 미치는 것으로 나타났다. 사전에 BPR을 수행한 결과에 따라 추가를 할수록 사용자 만족도가 높았고, 기능제공의 정도가 낮을 때 추가를 많이 할수록 조직의 경쟁우위가 높게 나타났다. 본 연구는 커스터마이징의 효과를 처음으로 실증 분석 하였으며, 기능제공의 정도, 사전 BPR의 정도, 구축 경과 기간 등의 여러 상황 변수를 도입 하여 연구 결과를 보다 의미 있게 해석하였다.
