Experiments were conducted to find out the optimum cultural conditions for micro-cross sectioned leaf segments of Gypsuphila paniculata L. Gerbera hybrida and Dianthus caryophyllus. Survival percentages of micro-cross sectioned segments were the highest in gypsophila, followed by carnation. Gerbera showed on survived segments. In gypsophila, segments thicker than 400㎛ were required to obtain over 75% survival. The percentage of adventitious bud formation was much higher with 600㎛ segment as compared with 400㎛. The regeneration of micro-cross sectioned segments of gypsophila was not sensitively affected by the auxins at varying concentrations. The elongation of adventitious shoot was promoted by kinetin compared with BA. In segments of 600㎛ thickness, adventitious shoot formation was promoted by BA compared with kinetin Adventitious shoot formation or shoot growth was not affected by KNO_3 concentrations with the segments of 400㎛ thickness. But adventitious shoot elongation was promoted significantly with segments in 600㎛ thickness. KH_2PO_4 (170 mg/1, standard concentration of MS medium) was effective for adventitious shoot formation. MgSO_4 also promoted adventitious shoot formation myo-Inositol tended to be suppressed regeneration of gypsophila.

Kim, Jin-Ill,Kim, Chang-Whan 한국곤충학회 1972 Korean journal of entomology Vol.2 No.1

이제까지 한국에서 기록된 꽃등에과의 곤충은 총 43속 93종에 달한다. 그러나 본인들은 한국의 꽃등에 상을 확실히 밝히기 위하여 1970년부터 꽃등에과의 채집을 시도하였고 또한 고려대 이공대 생물학과에 소장되어 있는 표본까지 합쳐 약 2,700개체를 동정하였다. 이 결과 4개의 속을 포함하여 17종이 한국 미기록종임을 알게 되었기에 보고한다. 따라서 한국산 꽃등에과는 47속 110종이 밝혀진 셈이다. 이번에 밝혀진 미기록종의 목록은 다음과 같으며 한국명칭은 모두 새로이 붙였다. 1. Pipiza favimaculata (점꽃등에), 2. Pipiza inornata Matsumura (검정좀꽃등에), 3. Cheilosia aterrima Sack (흐린날개별꽃등에), 4. Cheilosia ochripes Shiraki (뒷가슴가시털별꽃등에), 5. Epistrophe nigroepistomata Shiraki et Edashige (검정주둥이꽃등에), 6. Epistrophe omogensis Shiraki et Edashige (굵은줄납작꽃등에), 7. Xanthandrus comtus Harris (넉점박이꽃등에), 8. Syrphus confrater Wiedemann (대만넓적꽃등에), 9.

One Unrecorded Species of Acroceridae (Dipt.) from Korea

Kim, Chang-Whan,Kim, Jin-Ill 한국곤충학회 1972 Korean journal of entomology Vol.2 No.1

1972년 7월말에 제주도 한라산에서 한국산 미기록 꼽추등에과 Oncodes nigritarsis Shiraki(한라산 꼽추등에: 신칭) 4개체를 채집하였기에 보고한다. 참고로 한국산 꼽추등에의 기록종은 단 1종뿐이나 보고서마다 학명을 다르게 취급하였기에 이에 언급하고저한다. Acroceridae (Leach, 1815)는 과명자체가 Henopidae (Billb., 1820), Vesiculosidae (Bigot, 1852), Cyrtidae (Rondani, 1856), Oncodidae (Kertesz, 1909), Acroceratidae(Wu, C., 1940) 등과 같이 여러 Synonym을 가지고 있다. 뿐만 아니라 속명이나 종명에도 비교적 많은 Synonym을 가지고 있다. 이에 따라서 한국산 꼽추등에과는 단 1종이 알려져 있고 그 기록도 겨우 3개의 문헌에서만 찾아볼 수 있음에도 불구하고 각 문헌마다 사용된 학명이 다르다. 그래서 이 기록종에 대한 학명과 그 발표문헌을 명기하고 아울러 각 보고자의 채집지, 연월 및 분포를 참고로 수록함으로써 이 종의 취급자들에게 혼돈을 피하는데 도움을 주고져한다.

La, Mg 이온교환 ZSM-5 촉매의 제조와 촉매 산강도에 따른 MTO 반응 활성의 검토

김한일,황종현,정태환,정석진 경희대학교 산학협력기술연구원 1997 산학협력기술연구논문집 Vol.3 No.-

The MTO(methanol to olefin) process that aims at the production of olefins from methanol has attracted research interest because of its possiblity as another source of raw material in petrochemical industries. However its reaction path is not only ceased at the point of olefin production but also much amount of by products such as paraffins and aromatics that accelerate carbon deposit are produced. Thus the catalyst deactivation is rapidly progressed. In order to maximize the selectivity from methanol to olefin, alkylation and aromatization should be excluded from reaction path through catalyst and process variables. In this viewpoint, as a solution of the former problem, various metals were substituted on HZSM-5 which is used in commercial MTO process. With NH_3 TPD and activity test, the correlation between reaction products and possibility in control of Bro¨nsted acid site which is reported as the reaction active site was investigated. In this study, ethylene and propylene are the target products because of their wide applicating field.

The blood-sucking femaies of the horse flies were collected in Cheunra-Bukdo province, Korea from May to September in 1973. The results obtained are as follows. Three species of Arylotus miser, A. pallitarsis and Tabanus trigeminus are newly recorded from Korea. The blood-sucking horse flies more than 20 species distributed in this province. Both species of T. pallidiventris and T. amaenus among those are dominat, distributing all over the surveyed area and being about 50% of the total spedimens. Many of the species are collected from the end of June to early July, some bteeding in July to August. The number of species were 10 at the coast, 13 at the rice paddy field, 19 at the hill and 17 at the mountain areas, respectively.

청소년의 컴퓨터게임 이용실태, 부모양육방식, 개인의 정신병리

연구목적 : 오늘날 컴퓨터게임은 청소년기의 보편적 놀이도구가 된 상황임에도 불구하고 이들이 게임에 몰두하는 이유와 개인특성에 관한 정신과적 연구는 드문 실정이다. 이러한 필요성에서 본 연구는 중학교 2년 생을 대상으로 청소년의 컴퓨터게임 사용실태를 파악하고, 연관된 개인정신병리와 부모의 양육방식과의 관계를 밝히고자 하였다. 방법 : 이 연구는 서울시 노원구에 위치한 중학 2년생 124명을 대상으로 하였다. 정신병리의 측정을 위하여 한국판 간이정신진단검사(SCL-90-R)을 사용하였고, 부모자녀 결합형태 조사(PBI)를 통하여 부모양육태도를 알아보았다. 결과 : 1) 비록 과도한 시간을 들여 컴퓨터게임을 하더라도, 컴퓨터게임과 연관된 특정 정신병리는 발견할 수 없었으며 따라서 콤퓨터게임은 청소년기에 있을 수 있는 일상적인 놀이문화이다. 또 한대 부분의 청소년은 컴퓨터게임이 문제가 되지 않는다고 인신하고 있었다. 2) 남학생은 게임빈도, 게임시간, 게임방에서 보내는 시간, 게임을 한 번 할 때 지속하는 시간 등에서 여학생에 비해 통계적으로 의미 있게 높은 수치를 보였다. 3) 청소년의 신체증상호소, 타인간의 관계에서 나타나는 불편감, 우울증, 불안증의 정신병리는 컴퓨터 오락으로 인한 부작용과 의미 있는 관계를 보였다. 4) 게임빈도와 FBI상의 어머니 과보호척도는 정적인 상관관계를 보였다. 5) 게임을 하는 이유로는 공부, 학교 생활 등의 복잡한 것을 잊고 몰두하기 위해가 가장 많았고, 가장 심리적으로 부담이 되어 피하고 싶은 것으로는 학업문제였다. 6) 청소년은 게임방을 주로 친구들과 어울리는 공간으로 사용하고 있었지만 그 기능을 다하기에는 아직 보완해야 할 점이 많다. 결론 : 게임으로 인한 부모, 교사와의 다툼, 잦은 지각/결석, 친구들과 어울리지 못하는 등의 문제가 많은 경우에는 청소년 자체의 정신별리를 의심해 보아야 하며, 게임의 빈도가 의미 있게 높은 청소년의 경우에는 둥반되는 정서상의 문제와 함께 부모양육태도도 함께 세심하게 살피는 것이 필요하다. Objects : This study was designed or studying of current Korean adolescents computer game playing habits and exploring associations with parental rearing patterns and individual psychopathology. Methods : One hundred twenty our adolescents(age 13-15) who reside in urban area completed self-report questionnaires containing Questionnaires designed by authors, Symptom Checklist-90-Revision of Korean Version(SCL-90-R) and Parental Bonding Instrument(PBI). Results : 1)Computer game playing appears to be one of the social and leisure phenomena in these days. Although Adolescents spend a lot of times on computer game, Many of them perceive not problematic. 2)Compared with females, Male play computer games more regularly, more longer, spent more times in gamebang. 3)There was positive relationship between anxiety subscale in SCL-90-R and detrimental effects of computer game. 4)There was positive relationship between game frequency and maternal overprotection. 5)The main reasons for playing are "for an avoidance of stressful life events" , academic burden was the most troublesome issues in korean adolescents. 6)Many adolescents use gamebang as a social place, but they thought that gamebang is not good places to have a good time. Conclusion : This papers shows that computer game playing is a popular social leisure activity in Korean adolescents. And, Most of korean adolescents reported that they are suffered from pressure of academic achievements. They use computer game mainly by means of relieving academic pressures. In a heavy game users who have many conflicts with parents, teacher and who has frequent truancy and social withdrawal show significant anxiety. Maternal overprotection was observed in heavy game users. Authors recommended that clinicians should be careful in examining heavy computer game behaviors. Both underlying affective states and environmental influences, including family situations should be vicariously examined. KEY WORDS : Computer game · Gamebang · Game habits · Psychopathology · Parental rearing pattern.

Mycosis fungoides의 1例

高一香,金箕洪,高光烈,金世煥,許沅,池貞姬 中央醫學社 1968 中央醫學 Vol.15 No.3

This is a case of 27 year old male who had had severe pruritis with marked exfoliative dermatitis of 2 year duration, followed by skin tumor and, finally, visceral involvement. The death was complicated by bilateral bronchopneumonia with asperosilosis. In addition to clinical observation, characteristic histologic finding of cellular multiplicity with atypical histiocytes, immature reticulum cells and Pautrier's microab- scesses in the skin & axillary node serially biopsied made confirmed diagnosis of mycosis fungoides. At autopsy, multiple involvement of lymph node, predominantly periaortic nodes, kidneys, adrenals, stomach and pancreas was disclosed. Histopathologic picture of these, without doubt, was that of reticulum cell sarcoma but neither picture of reticulum cell sarcoma nor mycosis fungoides were observed in the skin lesion at autopsy. As clearly demonstrated in this case, the striking similarities of viseral metastasis in mycosis fungoides to lesions of other lymphomas pose quetion of common etiology, pathogenesis and host response. However, it would appear that mycosis fungoides is distinguishable early in the disease from other malignant lymphoma solely on the basis of its characteristic clinical course and cutaneous histopathology.

Angiomyolipoma occurs most commonly in the kidneys; the liver is the second most frequent site of involvement. Hepatic angiomyolipoma is a rare, benign, mesenchymal neoplasm, composed mainly of blood vessels, smooth muscle cells, fat, and myelocomponents. Radiologic findings are non-specific because the various elements of these neoplasms vary in their proportion and distribution within the tumor. Thus, data obtained by imaging technologies such as computed tomography, ultrasonography, or magnetic resonance imaging tend to be merely suggestive; definitive diagnosis usually requires histologic confirmation. We report here a case of angiomyolipoma in an incidental tumor of the liver of a 53-year-old female. Tissue was removed from the tumor by ultrasonography-guided gun biopsy and subjected to immunohistochemical analysis. Data showed that tumor cells were positive for HMB-45 and SMA, but negative for cytokeratin, anti-hepatocyte antigen, and α-fetoprotein. The patient did not receive any treatment and is being followed up. (Korean J Med 79:295-300, 2010)
