학문의 발달은 연구자들의 꾸준한 노력뿐 아니라 패러다임의 수호와 전환을 거치면서도 이루어진다. 패러다임의 수호와 전환은 변칙적인 사례에 대한 논의를 통해 이루어진다. 수학교육학 역시 몇 가지 탐구적 패러다임의 전환을 거치며 발달해왔다. 탐구적 패러다임의 전환은 이전 패러다임의 삭제를 의미하지는 않는다. 대신, 기존의 탐구적 패러다임이 건재하는 와중에 기존과는 다른 연구 목적 및 현상학적 기반을 가진 접근법이 발생함으로써 학계의 외연 확장에 기여하였다. 그러나 여전히 수학교육연구는 과학적이고 객관적이어야만 한다는 관점이 존재한다. 본고는 이러한 객관성이 모든 연구가 반드시 따라야만 하는 절대적인 원칙은 아님을 논증한다. 이를 위해 예술기반 연구를 일례로 제시한다. 예술기반 연구는 처음부터 객관적이기를 명백히 거부하며, 앎을 추구함에 있어 논리와 감성의 통합이 중요함을 주장한다. 연구 활동의 근본적인 목적이 지식 생산과 사회의 긍정적인 변화에 있다면, 예술기반 연구는 이러한 본질의 실행에 충실하다. 본고는 예술기반 연구의 기법 중 하나인 소설적 글쓰기 기법을 적용하여 수학교육연구를 수행하고, 그 결과물인 소설을 제시하였다. 그럼으로써 소설적 글쓰기 기법과 예술기반 연구를 수학교육연구의 주요 접근으로 받아들이는 것이 적합한가에 대한 학계의 논의를 촉발하고자 하였다.

Objectives Danggwisu-san (Dangguixu-san) is a herbal prescription frequently used to treat pain or swelling caused by contusion. To determine the expiration period through scientific methodology, stability of Danggwisu-san (Dangguixu-san) water extract, a herbal medicine, was examined under various storage conditions and periods. Methods Danggwisu-san (Dangguixu-san) was stored either at room temperature ($23{\pm}2^{\circ}C$), under a refrigerating condition ($4^{\circ}C$) or under a freezing condition ($-18{\pm}2^{\circ}C$) for 0, 1, 2, 3 or 4 weeks and then freeze-dried. Total phenol and total flavonoid amounts were investigated; contents of amygdalin (Prunus persica), paeoniflorin (Paeonia lactiflora), and glycyrrhizin (Glycyrrhiza uralensis) - the marker compounds of Danggwisu-san (Dangguixu-san) - were also analyzed through high performance liquid chromatography (HPLC). Results No significant change in total phenol and total flavonoid amounts was observed under the indicated storage conditions. Moreover, the contents of marker compounds, i.e. amygdalin, paeoniflorin, and glycyrrhizin, did not alter significantly under the indicated conditions, as well. Conclusions Danggwisu-san (Dangguixu-san) was found to be stable up until 4 weeks under the indicated conditions. Further studies on efficacy and long-term stability are warranted to establish the expiration period of Danggwisu-san (Dangguixu-san).

Objectives: Human indices were developed to determine returning point of residents and damage restoration after the chemical accident Methods: To determine the returning point of residents after the chemical accident, a new concept, the standard man model was introduced as a human index, in which both H-code and its acute effects were main idea. To evaluate the applicability, a hydrogen fluoride leakage accident in Gumi was applied. The returning point were suggested as the conservative remission period of acute effects among relevant hazard effects and compared with actual returning point. The coverage of each age group were considered with reflecting average daily dose expected for actual residents. In addition, a relief-index as a social-scientific approach was reflected as well to apply the damage restoration Results: Actual returning point of residents in Gumi was 88 days; and that of standard man model suggested was 84 days. The expected amount of exposure at aged 12 or under was at least 2.35 times greater than that of this model, 40s, theoretically. However, their population ratio was less than 1%, so 99% of residents could be applied when the standard man model was applied. The relief-index was as an objective and quantitative methodology to apply the qualitative aspect. Conclusions: Although evaluated as a relatively positive result, there was a limitation such as the number of accident applied to the verification of standard man model. The relief index was also considered, but further research should be carried out to find threshold level for the relief.

Meat quality is a very difficult term to define because it means different things to different people. When purchasing beef, consumers in the United States are likely to consider color, price, marbling level, subcutaneous fat trim, or cut thickness when determining the quality of beef. Once consumers have consumed the product, meat quality becomes exponentially more difficult to define due to the subjective nature of this term. Traditionally, tenderness, juiciness, and flavor have been considered the three most important factors that determine the palatability of beef. Therefore, American meat science beef research and industry focus has turned to measuring and quantifying these 3 attributes objectively and subjectively, and to determining what influences them. In reviewing the scientific literature, attempting to meaningfully summarize the findings of the thousands of studies on beef meat quality is impossible due to the inherent differences in the objective and methodology of studies. Fortunately, the United States beef industry and their national trade association, the National Cattlemen's Beef Association (NCBA), have conducted numerous surveys and audits to characterize the quality of the products being produced and marketed by their cattlemen and the palatability perceptions of their consumers. The data produced by these studies is quite large and impossible to summarize in entirety in this review. Therefore, this review concentrates on the most important attributes that determine the value of a beef carcass and objectively measured and consumer-assessed palatability characteristics of fresh meat from these carcasses from 1987 through 2010.

Recently, the oriental medicine industry in Korea has faced much hardship, due to the decreasing number of patients. Therefore, it is essential to investigate the reasons why patients are avoiding oriental medicine, because the percentage of people consuming medical service is an important marker that assesses the value of medical service. The researcher(s), based on theories on factors that affect health, health behaviors, and diseases, sought to find reasons why oriental medicine clinics saw a decline in the number of patients. Also, by proposing the problems inside the oriental medicine, I came to the following conclusion. -Because Koreans have low expectations for oriental medicine, they do not consider it as full medical service. Also, when they get sick, they are reluctant to seek oriental medicine because of reasons such as the limits of oriental medicine and check-ups, expensive medical cost, negative perception of oriental medicine, not enough support from the media, the old image of the oriental medicine and the little power the industry has on the society. -Among the inner problems of the oriental medicine community was the limitations that the science face on incurable and chronic diseases in terms of treatment and management, little professionalism, lack of scientific evidence, the attitude of the oriental medicine society, lack of sophistication in research methodology, and limitations in responding to changes in public health and the surroundings. The purpose of medicine is to eliminate the possibility of shortened life and dangers by treatment of diseases and health maintenance. For this to happen, structural and developed medical theories and means of treatment are necessary. The researcher hypothesizes that the problems that the oriental medicine society is facing mainly come from the lack of efforts and ability to provide such necessities.

Coprostanol is a metabolic product of cholesterol, formed by microbial action in the mammalian gut. This chemical compound is the major sterol in human and has been routinely studied as a biomarker of sewage pollution in marine and lacustrinesediments. This has led to the search for coprostanol as a biomarker in archaeologicalsoils, in order to detect the presence of fecal material. In this study, five samples of archaeological soils excavated at Wanggung ri, Iksancity, were used to assess the possibility of using coprostanol as indicators of ancient human activity in archaeological areas. The sampled soils were analyzed MXRD,EDXRF for their physical and chemical properties. And coprostanol was analysed byGC/MSD, using SIM method to detect and quantify specific compound. The results showed the soils were composed of quartz and feldspars, inorganicelement such as $SiO_2$, $Al_2O_3$, $Fe_2O_3$ etc. Moreover, the result from the analysis wasindicated that the specific compound is coprostanol. The coprostanol was determined at $0.16~1.01\mug$/g in the range of concentrations. This finding indicate that clear promise exists for the exploitation of coprostanol as biomarker of ancient human activity inarchaeological survey. Therefore such studies can serve to increase the confidence we place on biomarker-based methodologies for assessing fecal pollution. The application of this methodology has proved a simple and effective way of searching for that pattern in successively more aged deposits either known or suspected to contain fecal material. And the more scientific analysis of the soils will be showed to utility of the area ancient dietary life style, ancient environment.
