金荊玉,吳現道 제주대학교 1971 논문집 Vol.3 No.-

Citrus growing in Cheju-do, Korea has increased remarkably for the past several years. In 1971 the citrus acreage in Cheju-do will have increased to 150,000 acres(6,000 hectars). To avoid frost, citrus growing in Cheju-do is confined to the coastal area below 200 metes avove sea level. The average orchard size is limited to small unit size. This has necessitated a high level of attention to individual tree health and production in orchard management. But in Cheju-do citrus farmers have not been able to solve various problems corretly in order to obtain maximum yield with high quality. Therefore, the solution of these problems necessitates the use of the systematic application methods fertilizers to citrus. From the experimental results of the application of some fertilizers to citrus unshu and the analysis of leaves, we gained important knowledge regarding citrus unshu. The effectiveness of fertilizers was studied under normal field conditions and with pot experiment in the field. The amount of fertilizer applied as base fertilizer was divided into 17 treatment with 8 factors. The effects of nitrogen on the trees were significant increases in height, trunk diameter, number of leaves, and length of branches, but the other mineral nutrient did not show such effect. Through leaf analysis the low calcium concentrations and very high iron and copper concentrations were determined. The first fertilizer applications were made in 1969 and records taken for the period 1970∼1971. This report is only the first presentation of data collected. These studies will be continued through 1974.

The purpose of this study was to review for further understanding of the possible mechanisms of free radical formation during exercise and the relation of exercise and exercise induced oxidative stress and the antioxidant system. Acute or chronic strenuous exercise results in excessive production of reactive oxygen species(ROS). This ROS production may lead to lipid peroxidation and protein oxidation in the exercising muscle. Now, the results of study on the role of non-enzymatic defense system was not clear. Further study is necessary to get clear results of antioxidants. But, exercise induced oxidative stress may be reduced by antioxidant ingestion. Therefore, it is necessary to study on proper exercise for reduction of oxidative injury and for efficient practice of intensive exercise by antioxidant administration.

스포츠의 倫理 問題에 關한 考察

金道俊,全亨相 龍仁大學校 1996 용인대학교 논문집 Vol.12 No.-

Human beings live in the society, making the ethics. But, the society is leading the life of individuals with the ethics. So, to heighten the ethical level means to improve the mental life of siciety soundly. And, that the moral consciousness is weakened or degrades becomes the evidence that the society is being weakened to that extent. As mentioned above, it is said that the sports actions which are contrary to sportsmanship such as the doping for the improvement of competition power in sports society, or the violence in sports action and the cheating etc. frequently appear in the circle of sports and that the negative effect due to sports participation appears. While the scholars who stand in the position of characteristic of conflict doctrine reproach that the sports in modern society is even the drug, they are warning of the ethical corruption. Thus, so as to overcome this ethical issue, the sports shall be sublimated to the universal value of sports, through the spirit of fair play in sport, the security of public nature in sport scene and the security of freedom to be able to display individual ability to the utmost etc. It can be said that the solution method in the ethical issue situation in the sports circle applies the ideal self- world view as the corresponding phenomenon and that it was performed with the form of comment of practical current question. But, in this methodology, the universalized solution or the verification of truth is impossible by falling into the falsehood of idea. For exploding this situation of groping in the dark, it is deemed that it is necessary to study all the approach methods up to now on the basis of reflective thought. Thus, the sports ethics after this is to stop the beginning and end about the confrontation of practice of nearsighted characteristic without the theoretical frame and also to stop being absorbed in the formation of ideal world without analyzing the acutality completely. In keeping above fact in mind, it is considered that we may discover the order of sports circle.

실험시장 연구방법에 대한 개관 : 회계학 연구사례를 중심으로

AbstractThis paper describes the experimental market method as a research tool. This method was recently developed and began to be widely accepted as a proper research method in economic and business-related studies. It introduces the “experimental” methods of the so called “natural” sciences into social sciences. Using this method, the experimenter creates a microeconomic system, or a market, in a laboratory and studies what's happening in the system. A microeconomic system has three elements: an environment, an institution, and agent behavior. The chief advantages offered by this method are replicability and control. Replicability refers to the capacity of other researchers to reproduce the experiment, and thereby verify the findings independently. Control is the capacity to manipulate laboratory conditions so that observed behavior can be used to evaluate alternative theories. Due to these advantages, the experimental market method provides a means by which to test predictions from economic theories under rigorous and replicable experimental conditions that maximize internal validity, and also provides a feasible and low cost means for producing evidence on the effects of environmental and institutional variables. This paper also describes principles of experimental market method and provides guidance on how to conduct an experiment. To help researchers understand this new method, it reviews several accounting papers which use the experimental market method in their studies.

Partial or complete arrest of root formation is a rare complication caused by different factors that affects the permanent tooth during root development. The possible factors affecting this complication have been reported in dentin dysplasia, trauma, transmission of the periapical infection of the primary teeth to permanent tooth germ, radiation therapy, and congenital renal disease. One of these factors, traumatic injury to the primary dentition may cause a deflection or displacement of the permanent tooth bud. And the effects of trauma to Hertwig's epithelial root sheath which is essential to root development are the result of the transmission of the traumatic force through the surrounding bone or through the primary tooth. And it can cause critical damage to the normal root development. These tow cases show 2 children who complained of delayed eruption of permanent incisors, who have had a traumatic history during primary dentition. After clincial examination, because they have no more evidence of root formation of maxially lateral incisors. We extracted the permanent maxially lateral incisors which show partial or complete arrest of root formation. We concluded as follows; 1. These two cases show that one is a complete arrest of root formation when injured at 3 years old, the other is a partial arrest of root formation when injured at 5 years old. So, it is considered that direction and magnitude of traumatic forces and injured stage of permanent tooth bud will affect the root development. 2. It was noticed that there was an arrest or loss of Hertwig's epithelial root sheath in the histologic section of the extracted maxially lat. incisors. 3. After continuous observation, if there is a sign of partial or complete arrest of the root formation, impaction, or delay of the eruption of surrounding teeth after the normal root formation stage, extraction is indicated, and it is considered that orthodontic or prosthodontic treatment is needed.

This study required a comprehensive review of the literature referring to tropical special crops. The following information was extracted. Production of cereals increased by 35% from 1970 to 81, and this increase hepled to alleviate the world food shortage. With reference to tropical oil crops, Africa and Asia grew 90% of the total world production of groundnuts. Africa producted 70% of the world's castor bean. The chief producing area of the other oil crops was East/South Asia. In the production of tropical starch crops, cassava is increasing rapidly, sago plam is spotlighted as a new tropical starch crop. The production of sugar cane as a sugar crop increased by 37% from 1970 to 81, and the demand continues to rise, it has good future prospect s. The production of coffee and tobacco, recreation crops has not increased very much over the past 10 years. However, the yield's per area increased markedly. The acreage of cotton, a tropical fiber crop, increased by a mere 2% but yields increased by 30% over the past 10 years. The principal tropical fruits are bananas and oranges and the present production of each crop exceeds 40,000,000 tons. The main producing area for bananas is East/South Asia and for oranges is South and North America. Ecological examination of 90 species of recreation, fiber, starch, sugar and oil crops showed that only 13 species of recreation, fiber, starch, sugar and oil crops showed that only 13 species are distributed in subtropical zones out of 47 arbor crop species and 33 species are distributed in subtropical zones out of 43 species of herb crops.

저자들은 태생학적 기원, 면역조직화학적, 분자생물학적으로 완전히 별개의 암종인 갑상선 수질암종과 유두암종이 동시에 동일한 갑상선에 발생하는 매우 드문 사례를 경험하였고 이러한 현상이 우연한 동시 발생인지, 공통의 줄기세포 기원인지 혹은 공통의 암 유발인자에 의한 것인지는 여전히 논쟁의 여지를 남겨두고 있다. It is generally believed that the origins of medullary and papillary carcinoma of thyroid are embryologically different. So mixed medullary-papillary thyroid carcinomas are rare. The two separate tumors of the present case may be coincidental double primaries. It can be assumed that at least some of the mixed papillary and parafollicular cell carcinomas are results of collision of carcinomas derived from two embryogenetically different cell types. Recently, we experienced a case of mixed medullary-papillary thyroid carcinomas. A 50-year-old woman was found to have mixed medullary thyroid carcinoma and papillary thyroid carcinoma on the same lobe with lymph node metastases. We report a this case with literature review

전격성 제1형 당뇨병은 특발성 당뇨병환자에서 임상 경과가 짧고 진단 당시 심각한 대사 합병증을 동반하면서 췌장 효소 수치가 높고 췌도 특이 자가항체가 음성인 새로운 아형으로 알려져 있으며, 일본과 일본 외에서의 유병률에는 차이가 있는 것으로 보인다. 아직 전격성 제1형 당뇨병의 발생 기전은 명확하지 않으며 유전적 감수성이 있는 개체에서 바이러스 감염 등의 환경적인 인자와의 연관성이 가능한 병태생리로 제시되고 있으며 이에 대한 추가적인 연구가 요구된다. 저자들은 케톤산증으로 내원하여 전격성 제1형 당뇨병을 진단받은 증례를 경험하였기에 문헌고찰과 함께 보고 하는 바이다. Some patients with idiopathic type 1 diabetes have a fulminant disorder characterized by the absence of insulitis and of diabetes-related antibodies, a remarkably abrupt onset and high serum pancreatic enzyme concentrations. This is referred to as fulminant type 1 diabetes. A 29-year-old man suffering from abdominal pain, nausea and vomiting consulted to our hospital. Laboratory findings revealed high blood glucose level and the evidence of diabetic ketoacidosis, but the serum HbA1c was normal nevertheless. The low level of plasma C-peptide indicated the loss of endogenous insulin secretion. The patient satisfied the criteria for the diagnosis of fulminant type 1 diabetes. After the patient has been treated with insulin, his symptoms were improved and abnormal laboratory data were normalized. We report this case with a review of the literature

Tumor necrosis factor-α and interleukin-1β increases CTRP1 expression in adipose tissue

Kim, Kun-yong,Kim, Hwa Young,Kim, Jae Hyeong,Lee, Chul-Ho,Kim, Do-Hyung,Lee, Young Ho,Han, Seung Hyun,Lim, Jong-Seok,Cho, Dae Ho,Lee, Myeong-Sok,Yoon, Sukjoon,Kim, Keun Il,Yoon, Do-Young,Yang, Young Elsevier 2006 FEBS letters Vol.580 No.16

<P><B>Abstract</B></P><P>CTRP1, a member of the CTRP superfamily, consists of an N-terminal signal peptide sequence followed by a variable region, a collagen repeat domain, and a C-terminal globular domain. CTRP1 is expressed at high levels in adipose tissues of LPS-stimulated Sprague-Dawley rats. The LPS-induced increase in CTRP1 gene expression was found to be mediated by TNF-α and IL-1β. Also, a high level of expression of CTRP1 mRNA was observed in adipose tissues of Zucker diabetic fatty (<I>fa/fa</I>) rats, compared to Sprague-Dawley rats in the absence of LPS stimulation. These findings indicate that CTRP1 expression may be associated with a low-grade chronic inflammation status in adipose tissues.</P>
