This study was conducted to determine the optimum PH of vase water, buffer composition, effect of adding sucrose and/or 8-hydro-xyquinoiline(8-HQS), soaking hours and solution concentration using three varieties of rose and carnation. PH level of vase water was controlled from PH 2 to PH 7 at 1 intervals. Five kinds of buffer solutions were used. Cut flowers were soaked for 30 min, 12 hours, 24 hours and through experiments with concentration of M/10 and M/50. 1. In rose, fresh weight was increased, leaf wilting percentage and bent neck percentage were lower and fresh degree of flower were higher in PH 3. 2. In carnation 'Nora' and 'Kumkang pink', Fresh weight and fresh degree of flower were best in PH 3. Other investigations, however were best in PH 2 and PH 3. All investigations in 'Scarlet Valley' were best in PH 2. 3. Higher amount of water uptake in rose was observed in distilled were followed by PH 3. While PH2 and destilled water in carnation were good in decreased oder. All investigations were undesivable when PH levels were increased. 4. Buffer solution composed of citric acid and potassium citrate showed good results. 5. When added sucrose or 8-HQS alone and both of them to citricacid buffer no effects were shown, Compared to citric acid buffer alone. 6. Higher concentration and longer soaking hours showed good results and 30min. soaking also showed it's effect.

In order to investigate the water quality of the Kumho river, 7 sampling stations were chosen as the sampling site along the main stream. The result of the experiment are as follow; 1. In spite of the increasing flow by the rainfall, the concentration of DO showed lower than that of saturated DO except for downstream of Yeungchun dam, and showed DO sag at Gangchang bridge, particularly. 2. The concentration of BOD at Gangchang bridge showed 13.3㎎/ℓ, which exceeded the fifth grade of environmental criteria(BOD 8㎎/ℓ), in spite of the increasing flow by the rainfall. 3. The concentration of NH₃-N, NO₃-N did not showed adversely, which was the highest at Gangchang bridge and Paldal bridge, respectively. Also, the concentration of PO₄-P The highest at Gangchang bridge. 4. The concentration of heavy metals contained river water at Gangchang bridge was higher than that of other sites as(expressed in ㎎/ℓ)Cu:0.27, Cd:0.034, Mn:0.081, Fe:1.742, Zn:0.684, Cr:1.018, respectively. 5. The total bacterial counts were enumerated the highest as 3.0× 10^(7)cfu/ml at Ayang bridge and decreased when the sampling sites are changed from upstream to downstream. MPN appeared the maximum(24,000) at downstream of Yeungchun dam and the minimum(4,500) at Gangchang bridge.

MIM을 통해서 본 모-아 상호작용 연구

성영혜 숙명여자대학교 아동연구소 2005 兒童硏究 Vol.18 No.1

The Marschak Interaction method (MIM0 is technique developed to provide a structured way of measuring various aspects of the relationship between a parent and a child. It is a powerful tool, providing a "bonding assessment" that identifies both positive and negative aspect of the interactions between parent and child. It can be used as a diagnostic tool in a therapy situation, to help evaluate the effectiveness of treatment when used pre-and post-therapy, to help document any change between individuals in an experimental research situation, or to help provide a measure of change over time in longitudinal studies. There are very few other structured observation tool that provide such an opportunity to observe the kind of problem behaviors that are encountered in typical mother-child situations, the way a parent triggers, responds to, or handles a situation as it emerges. The potential value of this tool is wide ranging, and the MIM is likely to gain greater use as it becomes more widely known.

This experiment was investigated in the reacter of trickle bed with spherical particles. Flow of fluid and pressure drop were measured and analyzed in the air-water system. The results showed that liquid velocity at trickle-pulse transition increased with increasing packing size, and It decreased with decreasing gas velocity, and that theoretical model proposed was well applicable to predicted flow transition boundary. In the same operation conditions, Flow of fluid was changed with operation mode because of liquid closslinking. Therefore, As the maximum gas velocity increased, Pressure drop increased. Also pressure drop increased with increasing fluid velocity, and It increased with decreasing packing size, and the effect of gas velocity on the pressure drop for higher liquid velocity was less than that for lower liquid velocity in this conditions, Correlations in the flow of fluid and pressure drop can show in terms of Reynolds Number of gas and liquid phase.

We studied alpha particle detection characteristics of cellulose nitrate. LR115-Type2 and CA80-15 of Kodak Pathe'. With etchant of 60℃, 10% NaOH, optimum etching times for LR115-Type2 and CA80-15 are 90min and 30min, respectively. The relation between track hole diameter and etching time is same with Pareztke's results and energy dependence of track hole diameter is analogous to Benton's result.

최근 일간지에 보도된 정신병에 대한 기사 분석

김성완,윤진상,이무석,이형영 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.5

연구목적: 정신병에 대한 사회적 편견과 낙인은 질병의 예방, 조기치료 및 재활을 어렵게 한다. 이러한 부정적 시각은 다양한 대중매체에 의해서 강화될 수 있다. 본 연구는 질병에 대한 일반인의 인식에 큰 영향을 줄 수 있는 신문이 정신병에 대해 기술하는 내용을 분석하였다. 방법: 1998년 3월부터 2000년 2월까지 2년 동안 동아일보와 조선일보의 신문기사를 천리안의 뉴스복수정보 검색 프로그램을 이용하여 조사하였다. 검색어로는 일반인과 신문기사가 정신병을 지칭한다고 생각되는 정신분열, 정신병, 정신질환, 정신이상을 선택하였다. 이러한 검색어를 포함한 총 326건의 기사를 정해진 범주에 따라 분류하여 양적 및 질적 분석을 하였다. 정신병에 대한 시각을 알아보기 위해 신문기사를 부정적(직접적 또는 간접적) ② 객관적 또는 긍정적, ③특별한 시각 없음으로 분류하였다. 결과: 326건의 기사 중 부정적 기사는 직접적 177건, 간접적 51건으로 모두 228건(69.9%)이었다. 반면 객관적 또는 긍정적인 기사는 각각 29건, 14건으로 총 43건(13.2%)이었고 특별한 시각 없음은 55건(16.9%)이었다. 부정적 기사 중 가장 많은 것은 정신병 환자는 위험하거나 난폭하며 범죄를 잘 저지른다는 용을 전달하는 기사였다(118건). 이외에도 정신병 환자는 엉뚱하거나 특이하다(27건), 사회적 기능 행을 잘 못한다(18건), 정신병은 사회적으로 창피한 병이다(14건), 낫지 않는 만성질병이며 가족은 힘들고 부담스럽다(16건), 격리 수용해야 한다(6건)는 부정적 측면의 내용이 있었다. 또한 병의 원인에 대한 편견(18건), 상대를 비하하거나 어떤 현상의 심각성을 표현하기 위해 정신병이란 용어가 사용되는 경우(35건)와 더불어, 정신병원 입원에 대해서도 수용, 감금, 처넣다 등의 단어로 부정적인 기술(18건)을 하였다. 정신이상, 정신병이라는 용어를 사용하는 경우에 부정적 기사의 비율이 높았고, 기사에 환자가 직접 묘사되는 경우에 부정적 기사의 빈도가 높았다. 사건뉴스, 정치, 방송, 문화 기사에서 부정적 기사가 많았다. 반면 건강 기사에서 부정적 기사가 상대적으로 적었고 객관적 또는 긍정적 기사의 비율은 가장 높았다. 결론: 정신병에 대한 신문의 올바른 보도를 유도하는 것은 일반인의 질병개념 형성과 치료방법의 선택에 긍정적인 영향을 미칠 것이며, 나아가 환자의 효율적인 사회적응에 도움이 될 것이다. 이를 위해 정신병에 대한 신문기사의 부정적인 기술과 편견 전달을 체계적으로 모니터 하는 것이 필요하다고 생각한다. 또한 대중매체를 적극적으로 활용하여 정신병에 대한 정보를 일반인에게 사실적으로 전달하려는 노력이 요구된다. 중심단어:정신병·신문·대중매체·낙인·정신분열. Object: Social stigma and prejudice against schizophrenia hinder the prevention of the disease, early treatment and social rehabilitation. This stigma and the negative viewpoint against schizophrenia are enhanced by the mass media. This study investigated newspaper articles on psychosis, which strongly influence the public recognition of the illness. Method: The newspaper atricles of Dong-A Ilbo and Chosun Ilbo from March 1998 to February 2000 were reviewed through a news-searching program in Chollian. The search words, which were regared as psychotic illness, were Schizophrenia, Psychosis, Mental illness, and Mental derangement. A total of 326 articles were classified by category and analyzed quantitatively and qualitatively. The viewpoint of articles on psychosis consisted of these : ①negative(direct or indirect) ② neutral or positive ③ no specific viewpoint. Result: Of the 326 articles, the number with a negative description was 228(69.9%), the number with a neutral or positive description was 43(13.2%), and the number with no specific viewpoint was 55(16.9%). The most frequent negative theme was psychotic patients are dangerous or violent or may commit a crime(n=118). Other negative themes were these : psychotic patients are bizarre or grotesque(n=27), psychotic patients can't function in society well(n=18), psychosis is incurable and families should bear great burden(n=16), psychosis is shameful(n=13) and psychotic patients should be institutionalized(n=6). There were also prejudices against the cause of the illness(n=18), the description of psychosis in degrading terms(n=22) and the negative description of psychiatric hospitalization(n=18) with the words such as institutionalization, imprisonment and put into etc. In the artcles using the terms mental derangement or psychosis compared with mental illness, schizophrenia and in the articles describing psychotic patient compared with illness itself, the frequency of negative articles was high. Within each type of artcle, news, politics and culture artcles more frequently had a negative description, while health artcles less frequently had a negative description and most frequently had a neutral or positive description. Conclusion: There should be a program for monitoring newspapers for appropriate in-formation on psychosis. It might reduce social stigma and consequently help rehabilitation of psychotic patients. Also there should be endeavors to monitor other mass media and to develop a public education campaign through the mass media. KEY WORDS:Psychosis·Newspaper·Media·Stigma·schizophrenia.

In order to study the genetic causes of sterility in azoospermia and severe oligospermia, we investigated the sequences of the SRY (sex determining region of Y chromosome) gene that is known to determine the maleness of human. A 609 bp fragment of SRY open reading frame, containing the entire known SRY, was amplified from genomic DNA with primers XES2 and XES7. It was amplified from genomci DNA of one normal man, three azoospermic man and four severe oligospermic man. These amplified DNAs were subcloned for DNA sequencing. In this study, we found that normal, azoospermic and severe oligospermic men had the base of thymine at 155th codon region, while SRY sequence study by Sinclair et al. (1990) showed the base of cytosine. As a result, C → T transition mutation at 155th codon in SRY gene coding region had occurred but there was no change in the amino acid sequence [serine (AGC) → serine (AGT)]. It seems that the polymorphism in the coding region of SRY gene was found in Korean population for the first time.

The effects of additives such as La203, Nd203 and Sm203 on the phase stability microstructure, and electrical properties of the PbNb206 synthesized by molten salt(KCl and NaCI) method and solid state reaction were investigated. The results showed that small amounts of additives affected normal grain growth, i.e. inhibition of abnormal grain growth. The variations of Pbo/Nb205 ratio resulted in pillar and plate shaped find particles. The electromechanical coupling and mechanical quality coefficient of the lead metaniobate containing 3 mol% Nd203 were 0.13 and 75.0 respectively.
