In order to study the effects of administration of carbon tetrachloride(CCI$_4$) and 1-naphthylisothiocyanate(ANIT) on the liver of Korean black goats, some liver function tests and liver biopsy were done on 4 Korean black goats dosed with CCI$_4$(0.4m1/kg of body weight) in-traruminally and 4 Korean black goats dosed with ANIT(400mg/kg of body weight) by stomach tube. BSP Tl/2 and serum total bilirubin concentration in goats dosed with CCI$_4$ were increased gradually, reached to maximum value on 2nd and 1st day, respectively, and then began to decrease in normal range, gradually. In goats dosed with ANIT, BSP Tl/2 and serum total bilirubin concentration were increased rapidly, reached to maximum value on 0.5 and 1st day, respectively, and then returned to normal ragne, rapidly. Serum SDH, AST and GGT activities in goats dosed with CCI$_4$ were increased rapidly and reached to maximum value on 3rd, 1st and 2nd day, respectively. Thereafter, the serum enzyme activities began to decrease in normal range gradually. In goats dosed with ANIT, however, serum SDH, AST and GGT activities were not changed. The histopathologic changes in goats dosed with CCI$_4$ were lipidosis and centrilobular nee-rosis of the hepatic parenchyma. In goats dosed with ANIT, hyperplasia of bile duct epithelium was noticeable, but pathologic changes in liver parenchyma were not noticed. Conclusively, in Korean black goats dosed with CCI$_4$, main finding was necrosis of hepatic parenchyma. In Korean black goats dosed with ANIT, main finding was cholestasis.

Reduction of hydrogen chloride in the furnace of vertical type incinerator

( In-hee Hwang ),( Yuto Futagami ),( Takayuki Matsuo ),( Yasumasa Tojo ),( Toshihiko Matsuto ) 한국폐기물자원순환학회(구 한국폐기물학회) 2019 한국폐기물자원순환학회 심포지움 Vol.2019 No.1

Hydrogen chloride (HCl) in flue gas of municipal solid waste incinerator (MSWI) is generally removed by the in-duct injection of powdered slaked lime (Ca(OH)₂) before the bag filter (BF). According to the survey of operational characteristics of vertical type incinerator in 2016, the HCl concentration was considerably reduced before the application of dry scrubbing. Vertical type incinerator is a new type one which performs efficient incineration with forming pyrolysis, gasification, and carbon combustion zones vertically in thick waste layer. There is a possibility that HCl gas is reduced in the thick waste layer due to alkali and alkaline earth metals during long retention time. If this assumption is correct, chlorine (Cl) amount is relatively higher in bottom ash (BA) obtained from vertical type incinerator. In this study, the Cl distribution amount to BA, fly ash (FA), and cleaned flue gas as well as the form of Cl compound in ash were investigated to clarify the reduction phenomenon of HCl in the furnace of vertical type incinerator. Questionnaire survey and ash (BA and FA) sampling were conducted for twenty-four MSWI facilities to determine the Cl distribution amount depending on the types of furnaces. Annual amounts of waste incinerated, chemical for ash stabilization, BA and FA discharged were questioned. Flow rate and HCl concentration of flue gas at the outlet of BF were also investigated. BA and FA samples were provided to analyze total Cl content and the form of Cl and Ca compounds. Total Cl content was measured by the modified JIS method (JIS Z 7302-6). XRD analysis and leaching test were performed to know the form of Cl and Ca compounds. Leaching test was carried out under the conditions of LS=10, 200rpm, and 6 h. Cl concentration in eluent was measured by anion chromatography. Na, K, and Ca concentrations were measured by atomic absorption spectroscopy. In the vertical type of incinerator, HCl gas was expected to be captured by alkali and alkaline earth metals while it was passing the thick waste layer. However, there was no significant difference in the Cl distribution amount in BA depending on the types of incinerators as shown in Fig. 1. In order to confirm the possibility that HCl was captured by dust in flue gas at the furnace, dust sample was sampled from the duct before the spray of slaked lime. HCl gas concentration in combustion and post-combustion chamber of vertical type incinerator (V-1 facility) were also measured respectively. As a result, it was revealed that more than 30% of Cl contained in FA was derived from dust of furnace. In addition, it was found that HCl concentration was greatly reduced in the post-combustion chamber. From these results, HCl was considered to be captured by CaO which was contained more than 10wt% in dust at the post-combustion chamber of vertical type of incinerator. This HCl reduction on the furnace is an important phenomenon that leads to the reduction of the amount of alkali chemical required for exhaust gas treatment. It is necessary to verify whether the same phenomenon occurs in conventional stocker type incinerator. In our future study, the analysis of flue gas and dust will be performed by comparison with conventional stoker type incinerator to elucidate the mechanism of HCl reduction in the furnace.

인희교 한국스포츠리서치 2005 한국 스포츠 리서치 Vol.16 No.2

The purpose of this Study is to kinematically analyse Wenson Push Up motion which is C degree in dynamic muscular strength group to understand proper motion by difficulty. improve players' technique and moreover help coaches to check and estimate motions. To achieve this purpose, 5 male players who hold the high rank in sports aerobics national conference were selected and third dimension image analysis method by 2 high-speed cameras was used. 1. Moving displacement of the body center was shown 0.79±0.15 in El of X-axis and removed 0.98±0.15 to fingertip direction in E2. In E3 and E4. it appeared by 1.03±0.13. It appeared by 0.84±0.03 in Y-axis El. and moved to lower direction by 0.55±0.07 in E3. It is considered that the lower was body moving displacement on X-axis. the stabler was performance of difficulty. 2. In E2, Angle of right elbow joint was 148.52±10.35, Angle of left elbow joint was 166.3±11.39. In E3. Angle of right elbow joint was 79.34±21.30. Angle of left elbow joint was 64.24± 12.80. When right leg is placed on right upper arm. angle of left elbow is smaller than that of right elbow. This means adjusting bodily symmetry to show stable motion made angle of left elbow smaller. 3. Angular variation of right coxa was the smallest by 29.84±3.95 in E2, and the angle grow bigger gradually by 36.94±2.55 and 39.96±3.37 in E2 and E3. It is considered that while doing push-up. performing the motion with keeping small angle by trained muscle can be recognized as correct motion. 4. The speed variation of right tiptoe was fast in Phasel and Phased. In Phase2 and Phase3 the speed was decreased because while doing push-up, the speed variation of right tiptoe was not shown. This means fast performance of right leg in Phasel and Phased can show accuracy of the difficulty and size of the motion. Performing highly difficult motion in sports aerobic needs more trained muscular strength and flexibility. To make players perform accurate motion without any injury by systematical training, scientific study on ground reaction force and electromyogram is needed.

This study was performed to suggest a basic information on the living environment and elders welfare which are suitablie to the elders from their consciousness of habitation in the modern society in which the number of elders is gradually increased. The samples of this study were randomly selected 60 males and 58 females over sixty-year-old from apartments of Walker Hill, Jamsil Chokong and Daerim and Sajik place of pastime for the elders in Seoul. The method of ivestigation was based on the survey with questionares which were asking the preference of live together with sons and daughters or live alone, in the case of live together, with whom did they wish to live together, and as the factors of the preference, sex, age, education and the living status were analyzed. Statistical data analysis was made to obtain frequency, percentages, χ², degree of freedom and P by computer. The results obtained were summarized as follows. 1. Preference for habitation: It was shown that 71.7% of male and 63.5% of female elders prefer to live together with their son and daughter more females wish to live alone compared to males. As the factors of preference, the living status and the number of children were statistically significant but sex, age, education and condition of health were not found significant. 2. The children with whom the elders wish to live together: It was exhibited that 70.6% of samples wish to live together with the eldest son and daughter-in-law and 18.8% of samples wish to live together with the second son and daughter-in-law and only 5.9% of samples wish to live together with a daughter and son-in-law. As the factors of preference, age, education, living status and health condition showed a significance but sex and the number of children did not show any significance. 3. Reasons for live together with children: Economically profitable shpwed a significance in case the living status was low. Trustworth whowed a significance in case the living status was low and in female. The sweet performance of the great children did not show any significance. It is feel easy because of children's support showed a significance only in the case of low living status. It is comfortable bacause of sharing house affairs showed a significance only in the case of sex and living status. Traditional habit showed a significance only in the case of female and living status. 4. reasons for the preference of living alone: It is inconvenient because of the generation gap showed a significance in sex. It is uneasy because to pay attention showed a significance only in the high living status by living together and no significance was observed in other cases.

「敎育의 自由」(Ⅰ) : 學習權·學習의 自由 Intrinsic Human Right to Learn·Freedom to Learn

朴仁熙 경북대학교 교육대학원 1981 논문집 Vol.13 No.-

This thesis deals with such a contemporary fundamental legal principle of public educational law as Educational Freedom, especially Intrinsic Human Right to Learn·Freedom to Learn. Auther's examination is based upon following presumption that there be a differentiated system of particular legal logic, based upon reasonable educational logic, in public educ ational law from that of general public (administrative) law, and that there be not yet pointed out the fundamental legal principle of public educational law based upon above mentioned particular legal logic. Concretely speaking, this thesis purports to study and examine some of judicial decisions and the academic arguments on student's human right to learn·freedom to learn viewed from the relation to nation's power or competence in universal public education. Before the cases of so called Sugimoto Decision, by Tokyo District Court, on July 17, 1970, Academic Attainments Test Decision, by Supreme Court, on October 26, 1976 in Japan and Tinker v Des Moines Independent Community School District, 393 US 503, 1969 in U.S., nearly all challenges to the disciplinary authority of school officials were invariably held by the court in favor of school authorities and against objecting parents and students. The court held that the only constraint on the school's power to "define the offenses for which the punishment of expulsion may be imposed" was impermissible arbitrainess, and that the power of expulsion was not limited to previously adopted rules. In above mentioned decisions in both Japan and U.S., The court identified the student's intrinsic human right to learn·freedom to learn, altough a child regarded as someone in a captive audience and as someone who is not possessed of full capacity for individual choice. On the other hand, the court has also emphsized the need for comforming the comprehensive authority of the nation or state and of school officials, consistent with fundamental constitutional safeguards, to prescribe and control children's conducts in the school. Accordingly, problem liew in area where students in the excise of human right to learn. freedom to learn collide with the rules of the school authorities. The standard or measure adopted by the court is as follows: In order for the nation or state to justify prohibition of a particular expression of opinion, it must be able to show that it's action was caused by something more than a mere desire to avoid the discomfort and unpleasantness that always accompany an unpopular viewpoint; that is, because of undifferentiated fear or apprehension of disturbance is not enough to overeome the right to freedom of expression, it must be able to show that engaging in the forbidden conduct would "materially and substantially interfere with the requirements of appropriate discipline in the operation of the school." Auther's appreciation on the court decison is as follows: It must be noted and be paid attention that, relying on dessenting minor opinion said by Mr. Justice Black in Tinker Decision, based upon Contemporary public educational logic, the excise of free speech-symblic or pure-collided with orders or rules of school to "keep student's mind on their own scboolwork" is not permissible, even if it does not materially and substantially in terfere with the requirements of appropriate discipline in the operation of the school, and that it must be casted upon complaining the burden of showing that particular school measure was motivated by other than legitmate school concerns.

김은희,이현기,양영철,차인준 인제대학교 1990 仁濟醫學 Vol.11 No.3

Se 부족에 의하여 랫트의 체중과 사료 섭취량은 감소되었으며 혈중 LDH, GOT와 간장조직의 glutathion 농도는 정상보다 증가되었다. Se 부족군의 조직학적 소견은 간세포의 공포화 변성, 간조직의 PAS 반응 저하, LDH 활성화 감소 및 ACP 활성의 증가를 나타내었으며, rER의 분절화 현상 및 감소와 mitochondria의 종창 등이 관찰되었다. The objective of this study was to determine the effect of Se-deficient diet on the weight gain, chemical changes in plasma and microstructural change of liver in rat. Rats were divided into 2 diet groups (Se-deficient diet) and control diet and sacrificed after 21days of feeding. Levees of LDB, GOT, GPT of Plasma arid glutathione of liver were determined and light microscopic and electron microscopic observation of ret liver were performed. Total weight gaits (P<0.05) and feed efficiency radio (P<0.001) were significantly lower in Se-deficient group than in control group, whereas the levels of plasma LDH (P<0.001) and GOT (P<0.05) were increased significantly in Se-deficient group. Furthermore, the levels of total glutathione (P<0.01) and reduced glutathione (P<0.001) showed significant increase in Se-deficient group. Light microscopic observations showed that cytoplasmic blooning degeneration and pyknosis of nuclei were often found around portal canal of Se-deficient group by H-E straining. PAS staining also showed weakly positive reaction around central area, whereas PAS negative reacting cells were often observed around portal canal of Se-deficient group. Histochemical staining skewed that cytochrome oxidase activity were very active in both groups, whereas LDH activity was significantly decreased arid ACPase activity was significantly increased in Se-deficient group. Electron microscopic observation showed that the number of rER were decreased and the blooning degeneration of rEr was often observed in Se-deficient group. Mitochondria with mayeline figure arid wooly density were also observed in Se-deficient group. Light microscopic observations showed that cytoplasmic blooming degeneration and pyknosis of nuclei were often found around poral canal of Se-deficient group by H-E staning. PAS staining also showed weakly positive reaction around central area, whereas PAS negative reacting cells were often observed around portal canal of Se-deficient group. Histochemical staining showed that sytochrome oxidase activity were very active in both groups, whereas LDH activity was significantly decreased and ACPase acclivity was significantly increased in Se-deficient group. Electron microscopic observation stewed that the number of rER were decreased and the blooning degeneration of rER was often observed in Se-deficient group. Mitochondria with myeline figure and wooly density were also observed in Se-deficient group.
