박상규 ( Snag Gyu Park ),고희청 ( Hee Chung Ko ) 한국정보디자인학회 2013 정보디자인학연구 Vol.20 No.-

본 연구는 (주)충북소주에서 생산되는 시원한 청풍의 디자인 변경에 있어서 방향성이 다른 4가지 디자인 시안에 대해 각각의 호감도를 알아보았고, 좋아하는 요인에 대해서 살펴보았다. 그 결과 다음과 같은 세 가지 결론을 알 수 있었다. 먼저 지역 특성을 표현한 시안, 제품의 특성을 표현한 시안, 제품명의 의미를 표현한 시안, 젊은 느낌을 표현한 시안 등 4가지 디자인 시안 중에서 지역 특성을 표현한 시안의 호감도가 가장 높게 조사 되었다. 둘째, 4가지 디자인 시안 중 남성들은 지역 특성을 표현한 시안(4.06)을 가장 좋아하였으며, 여성들은 제품명의 의미를 표현한 시안(4.00)을 가장 호감도가 높은 것으로 조사 되었다. 셋째, 4가지 디자인 시안 중에서 20대들은 젊은 느낌을 표현한 시안을 가장 좋아했으며(3.74), 30대는 제품명의 의미를 표현한 시안을 좋아했다(3.91). 40대와 50대는 지역 특성을 표현한 시안을 가장 좋아하는 것(각각 3.88, 3.92)으로 조사 되었다. In this study, four design plans that would come up with different directions on design changing of Siwonhan Chungpung by Chung-buk Soju were examined to understand the public desirability about each design plan, and factors that would affect such desirability were also investigated. The results of the study are summarized as follows. First of all, amongst a plan to describe local characteristics, a plan to describe product features, a plan to describe meaning of the product name and lastly, a plan to describe young feelings, the very first one, the plan to describe the local characteristics, was observed to be preferred the most. Second, among the four design plans, men would rather go for the plan to describe the local characteristics while women take the greatest interest in the plan that would describe the meanings of the product name. Third, among the four design plans again, the twenties loved the plan with the young feelings the most (3.74) which was quite different from what the thirties would prefer the most that was the plan to describe the meanings of the product name (3.91). Regarding preferences of the forties and the fifties about the design plans, they appeared to love the plan that describes the local characteristics the most (3.88 and 3.92 respectively).

Glycine屬 亞屬間 雜種胚의 器內救出

정규화 여수대학교 1998 論文集 Vol.13 No.2

작물의 육종에서 야생 근연종은 다양한 유전자의 공급원으로서 중요하나 그들 유용유전자의 재배종으로의 도입 성패는 상호간에 존재하는 교잡불화합성의 극복에 달려있다. 본 연구에서는 대두와 그의 야생 근연종인 G. tomentella간의 아속간교잡에서 얻어진 발생초기단계의 배 또는 배주를 기내배양을 통하여 발아시키고자 하였다. 구형단계의 초기 잡종배는 0.1mg/1 IBA와 0.25mg/1 2-iP를 첨가한 B5배지에 배양함으로서 발아시킬 수 있었다. 또한 초기잡종배를 가진 배주를 0.1mg/1 IBA를 첨가한 B5배지에 배양하여 성숙시키고 0.1mg/1 IBA와 0.25mg/1 첨가한 B5배지에 계대배양함으로서도 배의 발아를 유도할 수 있었다. 그러나 이들 중 일부의 배양체는 칼루스화 되기도 하였다. Wild relatives of crop plants have been effectively employed in various breeding programs as additional sources of genetic diversity. This paper reports that the rescue of hybrid embryos between the soybean (Glycine max) and a wild perennial relative, G. tomentella, were accomplished through in vitro culture. The young embryos at the globular stage were matured and germinated by culturing on B5 medium supplemented with 0.1mg/1 IBA plus 0.25mg/1 2-iP. Embryos were also germinated by culturing ovules containing young embryos on B5 medium supplemented with 0.1mg/1 IBA for two month followed by culture on B5 medium supplemented with 0.1mg/1 IBA plus 0.25mg/1 2-iP. In some cases, however, the cultures proliferated to callus.

Suction Test를 이용한 부산점토의 시료교란 평가

정성교,김규종,제효성 東亞大學校 建設技術硏究所 2007 硏究論文集 Vol.30 No.2

Unusually thick and soft clay that called Pusan clay are distributed over the Nakdong River deltaic plain. Since the early 1990s, a large number of geotechnical investigation have been performed for reclamation works, which are to develop new lands for new port, road, residential and industrial complexes, etc in the plain. Sample disturbance on Pusan has been always become a disputable issue for the projects, because the geotechnical properties were extremely underestimated. Simultaneously with some efforts that minimize the sample disturbance, the possible causes and assessment of sample disturbance were necessary on the clay. Although there are several methods for assessing sample quality on clays, an attempt was made with suction measurement for this study. A careful attention was paid to retrieve samples from the ground at three locations and then suction testing was conducted. The measurement of suction pressure that were performed at the locations were analyzed with depth, which is to examine the intrinsic soil features. Their sample disturbance were also evaluated using the results, based on the methods that were proposed by Ladd and Lambe (1963) and Nelson et al (1971). In addition, correlations were performed using other soil properties.

정인원,김헌,홍주봉,지경환,이규영 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.6

연구목적 : 알코올 대사와 중추신경계내의 알코올 작용부위와 관련한 일부 후보유전자들이 알코올 의존과 관련이 있는지를 확인하고자 하였다. 방 법 : DSM-IV로 진단된 알코올 의존 환자 128명과 정상 대조군 128명을 대상으로 후보 유전자들의 다형성을 중합효소 연쇄반응과 제한효소처리법을 이용하여 동정하였다. 여기서 분리된 대립유전자와 유전자형에 따른 빈도의 차이를 유전자별로 각각 비교하였으며, 알코올 의존에 작용하는 서로 다른 유전자들에 의한 영향력을 배제하기 위하여 logistic regression 분석을 적용하였다. 결 과 : 알코올 의존군에서는 ALDH_2 유전자의 NN(wild type)형이 정상대조군에 비하여 유의하게 많았다(chi-square test, p<0.001). logistic regression analysis를 통하여 다른 유전자들에 의한 영향을 보정한 상태에서 ALDH_2가 NN(wild type)인 경우 다른 아형에 비하여 알코올 의존에 대한 odds ratio는 130.312이며 그 신뢰구간은 (17.22, 986.43)이었다. 한편, ASA는 N-glycosylation 부위에 변이형 대립유전자를 갖고 있는 경우(AG or GG)는 wild type에 비하여 알코올 의존에 대한 위험도는 2.344배이며 그 95% 신뢰구간은 (1.128, 4.871)이었다. 결 론 : 알코올 의존과 ALDH_2 유전자간에는 밀접한 연관성이 확인되었다. 또한 다른 유전자들은 개별 연관분석에서 의미있는 연관성이 관찰되지는 않았지만 logistic regression analysis를 통하여 N-glycosylation 부위에 다형성이 있는 ASA 유전자가 알코올 의존과 관련이 있음을 시사하였다. Objectives : This study was to explore the association between alcohol dependence and five candidate genes related to the metabolism of alcohol and the enzymes of the suspected sites in CNS. Methods : The genotype and allele frequencies of five candidate genes in 128 male hospitalized patients who met DSM-IV criteria for alcohol dependence were compared with 128 age-matched healthy male control subjects using polymerase chain reaction and restriction fragment length polymorphism. A logistic regression analysis was applied in order to exclude the reciprocal interactions among five candidate genes. Results : The NN genotype frequency of the ALDH_2 gene was significantly higher in alcoholic patients than in control subjects(chi-square test, p<0.001). No difference in frequency was found in the other four genes. In a logistic regression analysis, the odds ratio for alcohol dependence in the NN genotype of the ALDH_2 gene and AG or GG genotypes of the N glycosylation site on the ASA gene were 130.312(95% confidence interval, 17.22-986.43) and 2.344(95% confidence interval. 1.128-4.871), respectively. Conclusion : The result reiterates the association of the ALDH_2 gene polyporphism and the alcohol dependence. Logistic regression analysis additionally suggested that the N-glycosylation site on the ASA gene was associated with alcohol dependence.

A system with fast torque response is very beneficial in applications where direct self control(DSC) is highly desirable. The response of DSC is slower during startup and during change in command torque. Fuzzy control is used for implementation of DSC to improve its slow response. Simulation implementation of the fuzzy logic controller was carried out to verity the behavior of the controller. The simulation results with fuzzy control are compared with those of the conventional DSC. The starting flux and torque response and the responses to the step changes in command torque with fuzzy implementation show a considerable improvement over the conventional control. The steady state responses in both the cases are the same.

본 연구는 경북 청옥산(해발 1276.5m, 북위 37˚00'- 37˚05', 동경 128˚55'- 129˚00')의 남사면의 습지와 그 일대의 관속식물의 분포 및 보존대책 수립을 위한 기초조사로 수행되었다. 1998년 9월부터 1999년 8월까지 4회에 걸쳐 채집된 관속식물의 총수는 89과 268속 369종 1아종 57변종 7품종의 434종류이었으며, 이중 습지에 존재하는 관속식물은 총 67종류이었고, 습지형식물은 18종류이었다. 본 지역에 분포하는 한국특산 식물은 12종류이었으며, 식물구계학적 특정식물종은 55종류이었고, 본 조사에서 처음으로 남한에 분포가 확인 종류는 Lycopus uniflorus Michx.(털쉽사리) 1종류이었으며, 귀화식물은 9종류이었다. 본 지역의 습지는 인위적인 요인에 의해 심하게 훼손되어 본래의 상태로 회복시키는 것은 불가능하라라 여겨지며, 지금의 상태를 유지하기 위해서는 인위적으로 식재된 수목의 제거와 토사의 유입 방지, 유속을 더디게 하는 수로의 개선으로 습지환경을 형성시켜 주는 것이 필요할 것으로 판단되었다. This study was carried out to clarify the distribution of vascular plants of wet land and it's around area about south slope of Mt. Ch'ong-ok (1276.5m a.s.l., 37˚00'∼ 37˚05'N, 128˚55'∼ 129˚00'E), Kyungpook. The vascular plants, collected from September 1998 to August 1999 four times, consist of total 434 taxa; 89 families, 268 genera, 369 species, one subspecies, 57 varieties and seven forms. Among them, plants distributed in wet land were 67 taxa, hygrophytes 18 taxa. Korean endemic plants of this area were 12 taxa, and the special plant species based on floral region by Ministry of Environment(1999) were 55 taxa, new distrbutional plants of South Korea were one speceis, Lycopus uniflorus Michx, and the naturalized plants were nine taxa. The wet land in this area were destroyed seriously by artifical factors, therefore, may be impossible to restore original conditions, but the methods of being maintained present state is thought to be removed artifical vegetation, prevented to inflow of soils from around area and reconstructed waterway for delaying speed of runing waters and forming wet land environments.

Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps: one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.
