The purpose of this study is to fond out the expectation (class form, class method, class evaluation, and class environment) and satisfaction of Visually disabled students to physical education teacher. Here is a result of analysis according to their level of visual disable. 1.The expectation to PE teacher according to the level of disable. 1)class form (1)order movement (stand up, walking, greeting, changing direction, lining and formation.) Among male students, only perfect visual disabled students have strong expectation to PE teacher and the others (half disabled, high weak eyesight, medium weak eyesight, and low weak eyesight) have normal expectation. Among female students perfect visual disabled and half disabled students have normal expectation and others(high weak eyesight, medium weak eyesight, and low weak eyesight)have high expectation. We can make a conclusion that all visually disabled students have expectation to teacher in an order movement class. (2)Swimming class All students didn't expect anything, especially perfect disabled students strongly against it. (3)Judo, wrestling, Korea wrestling. All students have high expectation. Especially, female students have very strong expectation(over 90%) (4)Dancing (Traditional Korea dancing, other countries dancing, and creative dancing) All students (perfect and half disabled, high weak eyesight, medium weak eyesight, and low weak eyesight) have high expectation and over 85% student wanted it. 2)Teaching method (1)Teacher leading style Perfected disabled students have strong expectation in this class style and others have low expectation . (2)Student leading style Overall male students strongly against about this style and female students didn't want this style class and perfect disabled students have normal expectation. (3)unification style only perfect disabled students have normal expectation and others(high weak eyesight, medium weak eyesight, and low weak eyesight) strongly against about it. 3)Class environment Pefect disabled, high weak eyesight, medium weak eyesight, and low weak eyesight students have very high expectation of various books, many equipment, safety, and clean environment. 4)Class evaluation Overall students (Perfect disabled, high weak eyesight, medium weak eyesight, and low weak eyesight students) didn't want in the evaluation class. We know the fact that many visually disabled students have high expectation for P.E teachers. Especially, during dancing, and gymnastic class, they have very high expectation. But our real is not up to this. Various P.E material and strong economical supporting is needed to solve these problems through qualified teacher. According to the satisfaction difference study, the reason of difference satisfaction between sex, and economic level of the family is due to P.E class which is lack of understanding those problems between P.E program and students. To solve this problem, we must try to make a good program regard student's situation.

전기흥(Jeon, Ki-Heung) 한국상품학회 2011 商品學硏究 Vol.29 No.4

본 연구의 목적은 브랜드 확장에서 확장 제품군의 가격편차에 따라 확장제품의 가격전략을 어떻게 제시해야 하는 지에 대한 연구이다. 본 연구는 브랜드 확장 전략과 관련한 기존의 연구와는 달리 브랜드 확장의 가격편차에 따른 경쟁상황을 고려하여 연구를 진행하였다. 따라서 본 연구는 브랜드 확장과 관련하여 실무적 시사점을 제시해 줄 수 있다는 점에서 연구의 의의가 있다. 특히 브랜드 확장 전략에서 시장에 존재하는 브랜드의 가격이 확장제품의 평가에 직접적인 영향을 미친다는 점에서 확장 제품군의 가격편차는 매우 중요한 변수임에도 불구하고 기존의 연구는 이런 점에 소홀히 다루고 있었다. 본 연구는 브랜드 확장 연구에 확장 제품군내의 경쟁상황을 적용하여 가격전략에 대한 실험을 수행하였다. 분석결과에 의하면 확장 제품군내의 가격편차가 작을 때에는 고가격, 저가격으로 시장에 진입하는 제품에 대해서 주의 및 선호가 높았다. 그러나 확장 제품군내의 가격편차가 클 때에는 고가격일 때 주의가 높았지만 선호는 중가격일 때 가장 높았다. The main objective of this study is to investigate effect of price considering price variation of extended product category on brand extension. This research splits price variation of extended product category(intensive vs. disperse), price strategy(high vs. medium vs. low). The significant empirical research outcome: In the condition of intensive, consumers evaluated more positively on high price and low price strategy rather than medium price strategy. Also more attention. In the condition of disperse, consumers evaluated more positively on medium price strategy rather than high and low price strategy. But consumers more attention on high and low price strategy rather than medium price strategy.

목 적:단무지 공장에서 질식사고를 일으켰던 가스의 종류를 알아내고, 이러한 가스중독의 방서선학적 소견을 소개하기 위하여 본 연구를 하였다. 대상 및 방법:단무지 공장에서 발생한 질식 사고자 3예중 생존자 1예를 대상으로 단순흥부X-선검사와 CT 소견을 분석하였으며, 가스의 종류를 알아내기 위하여 단무지를 유리병에 넣어 발생된 가스를 가스크로마토그래픽을 이용하여 분석하였다. 결 과:단무지 공장에서 발생한 질식사고자중 생존한 1명의 방사선학적 검사에서 신속히 호전되는 폐경결(consolidation)을 볼 수 있었으며 이는 폐부종의 소견임을 알 수 있었다. 협기성 상태에서 단무지를 담은 유리병의 상층부 가스를 실험 분석한 결과 이산화탄소, 에칠알코올이 다량으로 검출되었으나 독성가스는 주로 황화수소이였다. 결 론:단무지 공장의 질식 사고자에서 폐방사선학적 소견은 폐경결을 보이는 폐부증으로서 이는 실험을 통해 단무지에서 발생되는 유독가스인 황화수소 때문임을 입증하였다. Purpose: To identify the main toxic gas released from salted radish in rice bran(Dan-M-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. Materials and Methods: Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analized by using the gas chromatography. Results: The radiographlc examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consolidations in both lung. The headapace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. Conclusion: Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.

현재 의료진단, 화학공정의 모니터링이나 환경공학적 감시 및 제어 등의 분야에서 사용되고 있는 기존의 센서는 고가이며 용적이 클 뿐만 아니라 분석시간이 길고 사용하기 까다로운 것 등 여러 가지 문제점이 있다. 또한 측정환경에 영향을 주지 않을 만큼 충분히 작으며 빠른 분석시간을 가진 센서를 필요로 하고 있다. 본 연구에서는 기존의 센서들의 난점을 극복할 수 있는 새로운 형태의 FET형 전해질(electrolyte : H^+, K^+, Ca^2+, Na^+)센서소자 및 분석 시스템, 용존가스(O_2, CO_2)센서의 개발을 중점적으로 추진하였으며, FET형 압력센서, 습도센서 둥의 개별 FET형 센서에 관한 기초연구도 병행하였다. The conventional sensors have many problems such as high cost, large dimension, long analysis time and troublesome handling to apply to the fields of medical diagnosis, monitoring of chemical process and environmental monitoring/control. The main objects of this research are to develope a new FET type electrolyte(H^+, K^+, Ca^2+, Na^+)sensors, analysis system, and dissoved gas(O_2, CO_2)senors that can overcome the problems of the conventional sensors, and parallel basic researches on FET. type sensors such as pressure and humidity are also in progress.

The purpose of this study was to evaluate the effects of fluoride application on the aspect of shear bond strength of three aesthetic restorative materials to dentin. One light-cured composite resin(Palfique Esterite) and two light-cured glass ionomer cements(Fuji Ⅱ LC and Compoglass) were used in this study. 120 permanent molars were used for this study. The teeth were extracted due to the origin of periodontal disease. The crowns of all teeth were removed, and the remaining roots were embedded in epoxy resin. The mesial or distal surfaces of roots were ground flat to expose dentin and polished on wet 320-, 400-, and 600 grit SIC papers for a total of 120 prepared flat root dentin surfaces. The prepared samples were divided into six groups. Group 1, 3, and 5 were control groups and group 2, 4, and 6 were experimental groups. Sixty samples for experimental groups were treated with 2% NaF solution for 5 minutes. Group 1 and 2 were bonded with Plafique Esterite, group 3 and 4 were bonded with Fuji ll L(and group 5 and 6 were bonded with Compoglass. After 24 hours water storage at 37±1℃, all samples were subjected to a shear to fracture with Instron universal testing machine(No.4467) at 1.0㎜/min displacement rate. Dentin surfaces treated with each conditioners before bonding and interfacial layers between dentin and aesthetic restorative materials were observed under Scanning Electron Microscope(Hitachi S-2300) at 20Kvp. The data were evaluated statistically at the 95% confidence level with ANOVA test. The result were as follows; 1. Among the control groups, group 1 showed strongest bond strength and group 3 showed weakest. 2. Among the experimental groups, group 2 showed strongest bond strength and group 6 showed weakest. 3. Statistical analysis of the data showed that pretreatment of dentin with 2% NaF solution significantly decreased the bond strength of three aesthetic restorative materials to dentin(P<0.05). 4. SEM findings of fluoride treated dentin surfaces(2, 4, 6 group) demonstrated dentin surfaces covered with fluoridated reaction products. 5. Except group 4 and 6, resin tags were formed in all groups.

during the period from 1965 to 1979. We examined the data of year book of fisheries statistic and puffer catches by long line in the yellow sea (Gun san) during the period from 1977 to 1 This paper dealt with the result of investigations on puffer in the yellow sea of Korea 979. At the same time the oceanographic data in yellow sea of Korea was collected during the periods of February and August from 1977 to 1979. The results obtainted are as follows 1.Judging from the fisheries fluctuation during the period from 1965 to 1979, the total catch is increased every four years, but decreased every three years. 2.The rate of puffer catches showed 50.6% in the yellow sea, 37.6% in the southern sea, 11.7% in the eastern sea and Gun fan is a strategic area of puffer catches out of other province of Korean sea. 3.Annual catches of puffer reach 61.5% by the long line. The avelage annual catch for the past 15-years is 4,482.9 M/T, and the variation coefficient; C.V; is 29.3, thus the fluctuation by the year is not so irregular. 4.Puffer catches in the yellow sea during the period of puffer migrating toward the north from 1977 to 1979 showed 0.27 M/T, while during the period of southward moving it showed 0.15 M/T, and the whole fishing season of puffer catches showed hi앙or value in the years of 1965, '69, '73, '77 and than in the years of 1966. '72, '76. 5.It's fishing ground was formed with in connecting line of yellow sea (124˚-127˚E, 32˚5'-37˚2'N) and the Geok Yeol Bee Do is the fishing ground in summer and Heug San Do in Autumn, southwestern of Je Ju Do in winter. 6.From the view point of the relation between the oceanographtic conditions and the formation of fishing ground, full catches are showed when the warm current distributes along the coast 7.The deep water temperature at which puffers are caught during the whole fishing season varies from 8℃ to 22℃ in the yellow sea of Korea Judging from the oceanographic conditions at equations the optimum water temperature for puffer migration seems to be 16˚-20℃, showing that the most favorable temperature for catch is 18℃

A preliminary study to evaluate the effect of thyroid function on the bone mineral density(BMD) was done. BMD was measured at lumbar spine 2, 3, 4 (A-P view) in 10 euthyroid nodular goiter, 8 primary hypothyroidism and 20 hyperthyroidism patients, perimenopausal or postmenopausal periods. Serum calcium, phosphorus, thyroid hormone concentrations and other parameters were measured to analysis. The results were as follows. 1. The BMDs of euthyroidism, hypothyroidism, and hyperthyroidism were 0.85± 0.16gm/㎠ (M±SD), 0.83±0.29 and 0.79±0.16 respectively, without any significant difference, but the BMD of hyperthyroidism was lowest. 2. The BMD of postmenopause of all thyroid disease patients was significantly lower than that of perimenopause patients. 3. There was no significant relationship between BMD and serum calcium, phosphorus, T_3, T_4 or duration of treatment for thyroid disease. In conclusion, the BMD is affected mainly by the age and thyroid function, so attention to osteoporosis must be considered for the patients of thyroid disease in menopause.
