화학적 불임유기물질 Hempa가 쌀바구미(Sitophilus oryzae L.)에 미치는 생물학적 영향 및 불임성의 전달에 관한 연구

심재욱 한국응용곤충학회 1973 한국응용곤충학회지 Vol.12 No.1

Some experiments were conducted to investigate the effects of the chemosterilant, hempa, on the biology of the rice weevil, Sitophilus oryzae L., and the transmission of the lethal factors in the progeny. One to three days old adult males were fed on the wheat grains treated with concentrations of 0.0625, 0.125, 0.25, and of hempa water solution. The effects of the treatment on the mortality, longevity, and the performance of oviposition were examined for the Pl generation, and the hatchability and mortality in the postembryonic development were also tested in the generations to analyze the inheritance of the lethal factors. The results obtained were summarized as follows. (1) The average longevity of the treated males were ranged from 26.6 to 30.4 days, and indicated no statistical differences. (2) The mortality of the treated males were ranged between and showed no statistical significance. (3) The overall mean number of eggs laid by a female mated to a treated male with concentrations of 0.0625, 0.125, 0.26 and were 3.78, 4.05, 3.75 and 3.61 for the respective treatments, and they were not differ significantly from those of control which were 3.60 per female per 3 day period. The unmated female laid 1.91 in the same period, and significantly differ from those in other experimental groups. (4) The overall mean hatchability of the eggs laid by the females mated with males that had been treated with various concentrations of hempa were 86.82, 64.77, 53.47, 40.33 and for the respective concentrations of 0, 0.0625, 0.125, 0.25 and . The hatchability decreased with the increasing concentrations. (5) The minimum hatchabilities were obtained from the eggs laid in the period of 10-12 days after treatment, then the hatchability increased showing some recovery. The recovery seemed to be very much delayed for the males which had been treated with the greater concentrations. Such a difference in hatchability might be related with the sensitivity of the developmental stages of the sperms, and broader spectrum in the stages and severer effects seemed to be associated with the increased concentrations. (6) The overall mean of larval mortality in the generation were 6.55, 17.89, 27.40, 35.42 and for the respective concentrations of 0,0.0625, 0.125,0.25 and . And there was a tendency to increase in the mortality with the increase of concentrations. (7) The correlation coefficients between per cent sterile eggs and larval mortality for the experimental plots of 0.125, 0.25 and treatments showed r=+0.83 and +0.85, respectively, and it seemed to be close correlation between the lethal effects on the embryonic and post-embryonic developments. (8) Since the of the sterile eggs was and of the larval mortality was , it was considered that tile lethal factors expressed more in the egg stages than the larval stages. (9) The ratio of female to male in the adults showed 100 : 125, 100 : 108 and 100 : 124 for the plots of 0.125, 0.25 and treatments, respectively. And it n·as considered that the sex ratio distortions might occur with the higher concentrations. (10) When the F, males originated 1.on the eggs had been laid by p, in the period of 16-18 days after treatment, were crossed to normal females and made sib matings , the per cent sterile eggs of the generation were 13.88 and , and were 31.01 and for the generation with the plots of 0.0625 and treatment, respectively. And these seemed to be a results of the individuals are carrying some chromosomal aberrations (11) The larval mortality was the highest in the plot and followed the female backcross plot, and the least in the male backcrosses. (12) The proportions of 1st and 2nd instar larvae among the larval development at tile 17th day after oviposition were 10.98, 27.26, 32.98 and in the normal female normal male, femalenormal male, normal male and male plots, respectively. It was considered that the larval development might be delayed by the treatment in the 2nd generation. (13) Per cent larval mortality and sterile eggs were greater in the sib mating plots than both of backcrosses. Therefore, it seemed that some of the recessive lethal mutations might affect in the further generations. (14) The sterility, induced by the treatment of chemosterilant, hempa, was considered as the result of the dominant lethal mutations due to chromosomal aberrations such as translocation and/or deletion. The effects of these lethal factors seemed to be inherited tip to 3rd generation after treatment. 본 실험은 Hempa 처리가 쌀바구미 (Sitophilus oryzae L.)에 미치는 생물학적 영향과 부분불임성의 유전성에 미치는 영향을 조사하기 위하여 우화후 1-3일된 숫컷을 및 의 Hempa로 처리된 소맥에서 2일간 섭식처리하여 당대의 치사율, 수명 및 산란수에 미치는 영향을 조사하고 세대에 미치는 처리효과를 조사하여 다음과 같은 결과를 얻었다. (1) 처리웅충의 평균수명은 대조구에 비하여 차가 없었으며 당대 치사율도 처리시 보정 치사율은 로 유의차가 없었다. (2) 처리웅충과 교배된 정상 자충의 3일간 평균 산란수는 무처리구 3.60에 비하며 구에서 각각 3.78, 4.05, 3.75 및 3.61개로 유의차가 없었으며 비교배자충 구에서는 1.91로 현저한 산란수의 감소를 보였다. (3) 처리웅충과 무처리자충의 교배에서 얻은 대의 처리후 27일간 총평균 부화율은 대조구 에 대하여 구에서 각각 로 처리농도의 증가에 따라 부화율이 감소되었다. (4) 처리후 산란 시기별로 산하된 란의 부화율은 모든 처리구에서 처리후 10-12일까지는 부화율이 감소하다가 그후 다시 증가하는 회복현상을 보였다. (5) 고농도 처리구인 구에서는 처리후 1-3일에 산하된 란의 부화율이 낮았고 10-12일 이후에도 회복의 속도가 느렸다. 이와같은 현상은 배우자 형성 과정에서 영향을 받는 시기의 범위가 넓기 때문이라고 생각되었다. (6) 유충기 치사율은 대조구 에 비하여 구에서 각각 로 처리농도의 증가에 따라 치사율의 증가를 보였다. (7) 난기 치사율과 유충기 치사율의 관계는 처리구에서 상관계수가 각각 r=+0.89, +0.83 및 +0.85로 난기 치사와 유충기 치사는 동일형의 영향임을 알 수 있었다. (8) 치사인자 발현에 대한 난기와 유충기의 감수성은 각각 및 초 난기가 유충기보다 감수성이 쳤다. 또한 미우화에 미치는 영향은 이들 둘의 공동작용의 결과임으로 로 더욱 감수성이 컸다. (9) 대의 우화 성충은 처리구에서 암컷대 숫컷의 비율이 100 : 125, 100 : 108 및 100 : 124로 숫컷의 출현빈도가 높은 듯 하였으나 우화 개체수가 적은 관계로 통계적인 유의성은 없었다. (10) 이 처리후 16-18일에 산하한 난에서 우화한 웅충을 무처리 자충과 교배하였을 때 구에서는 구에서는 의 난기 치사율을 나타내었고 도 각각 와 의 치사율을 나타내고 있어 염색체 이상의 결과라고 생각되었다. (11) 세대의 유충기 치사율은 자충 퇴교배구가 웅충 퇴교배구 보다 높았고 형매교배에서 가장 높았다. (12) 및 세대의 유충발육은 산난후 제17일에 1-2영충이 대조구 에 비해 자충 퇴교배구, 웅충 퇴교배구 및 구에서 각각 및 로 분화의 지연작용을 나타내는 듯하였다. (13) 세대에서도 난기 및 유충기 치사율이 형매교배구가 퇴교배구 보다 높았다. 이는 열성치사인자가 영향한 때문이라고 생각한다. (14) Hempa 처리에 의하여 유기된 불임은 주로 전좌나 결실과 같은 염색체 이상로 유기되는 우성치사돌연변이에 기인된 것이라고 생각되었으며 이들 인자의 영향은 처리 후 제3세대에까지 전달됨을 알 수 있었다.

심재욱 대한영상의학회 1990 대한영상의학회지 Vol.26 No.3

Arachnoid cysts are benign developmental cysts that occur in the cerebrospinal axis in relation to the arachnoid membrane, and contain clear, colorless fluid resembling normal cerebrospinal fluid. Authors retrospectively analysed 24 brain CT scans of 23 patients with pathologically proven arachnoid cysts that were examined at Wonju Christian Hospital from jan. 1985 to Dec. 1989. The results were as follows; 1. The common clinical symptoms were headache(9cases), others were hydrocephalus, visual distrubance and bulging of the scalp. 2. Arachnoid cysts in supratentorial region were 14 cases, most of them were located in middle cranial fossa(9cases), and infratentorial locations were 10 cases, most of them were located in retrocerebellar area(7cases). 3. Shape of the arachnoid cysts were quadrangular with straight inner margin(11 cases), spherical with convex inner margin(8cases), and others(5cases). 4. Of 14 cases with supratentorial region, most of them(10 cases) showed quadra gular shape with straight inner margin. Of 10 cases with infratentorial region, most of them(7cases) showed spherical shape with convex inner margin. Of 9 cases with middle cranial fossa region, most of them(8cases) showed quadrangular shape with straight inner margin. 5. Size of the arachnoid cysts, in the greater diameter was commonly distributed between 3 and 7 cm(12 cases)

[舊日本海軍 朝鮮人軍屬 關聯 資料(2009)]의 微視的 分析

심재욱 한일민족문제학회 2013 한일민족문제연구 Vol.24 No.-

日帝が恣行した「強制動員」は日帝植民支配の欺瞞的な行為を赤裸々に示されることが韓国歴史研究にとって非常に重要な意味があると思う。同時に大勢の韓国人の個人史にまで悪影響を及ぼし、60年余りが過ぎた今までも各々の人生に傷付いていて社会問題の一つとして残っていることから見ると、その問題の深刻性が十分分かる。しかし解放されてから60年余りが過ぎているうちに韓国社会はあの被害把握に対して無関心な態度で目を逸して来た。2004年11月「首相官邸所属の日帝強占下強制動員被害真相究明委員会」(以下委員会)の立ち上げを契機に関連研究と実体把握が以前より活発にして、研究が活性化することは大いに励みになる事だと言える。それにも関わらず、今なお強制動員に関する研究には多くの眼界がある。この限界を突破する作業として必要なのは直ちに今現在、国家記録院で所蔵している約48万人分に至る関連名簿資料である。この資料は戦時の動員過程と戦後の復員過程で強制動員の主体である日本から作成された資料と言う側面と、全体的な分析によって「いつ、どこ、いくら、どこに強制動員されてどんな被害を受けたか」のような強制動員に対する全般的な実体把握が出来ると言う側面ですごく意義深いと思う。それでも、これに対した研究分析は殆んどない状況である。本稿は強制動員の全体像を把握するために必要な基礎的作業で、2009年日本政府が「委員会」に直接提供した[舊日本海軍朝鮮人軍屬関連資料(2009)](以下「舊海軍軍屬資料(2009)」)に収録された各種文書の内容と性格について考察した。「舊海軍軍屬資料(2009)」は1991年に日本政府が提供して、現在は国家記録院で所蔵している[舊海軍軍屬身上調査表]を基にしている。しかし「海軍工員名簿」、[供託金文書]等多数の新資料を収録しているので今までの資料とは異なる新たな性格の資料だと思う。そして、本稿に書かれたように海軍軍屬動員に関して戦時と戦後に多くの文書が作成されている。ところが、韓国政府に提供されたのは[舊海軍軍屬身上調査表]に過ぎない。追加的に入手すべき抜落ち資料を把握した側面で本稿の研究の意義がある思われる。本稿で筆者が行われた作業は「軍屬動員」の把握を通じて強制動員の全体像を考察しようとする一連の連続的作業である。このような資料の内容と性格に対する分析を基にして、今筆者は当該資料のデータをエクセルのファイルに書き込んでデータ化する作業をしている。今後行う詳細な分析は、今まで確認されていない海軍軍屬動員の実体が探れる重要な基礎的作業になると思う。 ‘Forced Mobilization’ under Japanese colonialism has a significant meaning to Korean studies, considering it accurately represents the deceitfulness of Japan’s colonial rule. Forced Mobilization also made unwelcome changes in a number of Korean people’s personal histories and it is still a lingering social issue of Korea. However, Korea has dealt with the matter with indifference over the last 60 years since Korea’s liberation. It is highly encouraging to learn that the studies and investigations on ‘Forced Mobilization’ have been improved and carried actively out since the establishment of ‘the Commission on Verification and Support for the Victims of Forced Mobilization under Japanese Colonialism in Korea(henceforth ‘the Commission’)’ under Prime Minister in November 2004. Nonetheless, we still have the limits in the studies on Forced Mobilization. The study on the registers of the approximately 480 thousand Korean names owned by National Archives of Korea is quite important in order to overcome the limits. As the registers were recorded by Japan during the period of war and demobilization, it can play an essential role to find the actual conditions of Forced Mobilization, such as when, how many, from where to where, and how much damage the Koreans had to be received. However, the study and analysis are still insufficient. In this study, as a groundwork for getting the general idea of Forced Mobilization, I examined the contents and its features of ‘the Document of the Korean Employees in the Japanese Imperial Navy(henceforth the Document)’ that the government of Japan directly gave to the Commission in 2009. The Document is based on ‘the Table of the Civilian Employees in the Japanese Imperial Navy’ given by Japan and currently owned by National Archives of Korea. As the Document includes new information, such as ‘the List of the Naval Factory Worker’ and ‘the Documents of Deposit’, it could be considered as new and valuable data to study. One more achievement of this study is to find the missing materials to be returned later on. ‘The table of the Civilian Employees in the Japanese Imperial Navy’ was the only material offered to the government of Korea by among many missing documents recorded in the state of war and after the war. What I did in this study is a part of the ongoing researches aiming at understanding the big picture of Forced Mobilization by taking in the situation of the mobilization of civilian Employees. Based on the data and its analysis, I am currently working on making the database. Detailed further analysis would be a substantial groundwork to discover the unidentified reality of the mobilization of Civilian Employees in the Japanese Imperial Navy.

멸구 매미충類에 對한 藥劑抵抗性의 遺傳性에 關한 研究 1 : 애멸구의 MEP 劑에 對한 藥劑抵抗性의 遺傳的 特性

沈載昱 한국응용곤충학회 1978 한국응용곤충학회지 Vol.17 No.2

본 시험은 애멸구의 MEP제에 대한 저항성이 유전적 특성에 기인된 것인지를 알아보기 위하여 나주지역의 야외집단을 채집하여 감수성인 실험실 계통과 교배하고 및 에 대하여 Probit 법으로 분석하고 을 비교한 결과는 다음과 같다. 1. 나주지역의 애멸구 야외집단은이 자충충의 경우 0.0029ug/충으로 감수성인 실험실계통의0.0008ug/충에 비하여 저항성의 차를 타나내었다. 2. 나주지역 야외집단이 나타내는 저항성은 과 의 분석에서 및 사충율의 회귀가 저항성인 친쪽으로 가깝게 나타나는 경향을 보여 유전적 특성에 기인된다고 생각되었다. 3. 집단의은 양친의 중간 정도였으며 넓은 분산을 보이고 있어 MEP제에 대한 저항성의 유전은 수개의 유전자가 관여할 것으로 생각되었다. The study was conducted to determine the inherited properties of the MEB resistance to natural population of the small brown plant-hopper(Laodelphax striatelluss). The plant-hoppers were collected from the natural population of Naju area where the highest insecticide resistance of MEF to the green rice leaf hopper (Nephotettix cincticeps) have been examined in 1976. And Naju collections were crossed to the susceptible Lab stock to examine the MEP resistance in the and populations. Ail the data were analyzed by the probit method. There was a difference in MEP resistance between Naju collection and susceptible Lab stock, showing value of the former was 0.0029ug/insect compared to 0.0008ug/insect for the later. The values and dosage-mortality lines of the and tended to close their resistant parent. and it was considered that the character of the MEP resistance in the Naju collection of the small brown plant hopper was controlled by the genetic traits. However, value and dosasage-mortality lines of the populations were intermediate to their parents, it would be conclusive that the trait will be governed by a interaction of the genes or factors rather than the single genic control.

자궁내막암 임상 병기Ⅰ과 Ⅱ에서 수술중 동결 절편 진단의 정확도

심재욱,홍성란,정환욱,박인서,임경택,김태진,박종택,이승호,이기헌,김의정 대한산부인과학회 1998 Obstetrics & Gynecology Science Vol.41 No.5

이상의 결과로 보아 자궁내막암의 수술에 있어 동결 절편 진단을 시행함으로써 집도의가 골반 및 부대동맥 임파절에 암세포 전이의 고위험 요소를 선별할 수 있도록 하여 치료방침 결정에 중요한 역할을 할 것으로 사료된다. From January 1991 to December 1996, a comparative analysis was conducted on 45 consecutive patients underwent hysterectomy for FIGO stage I & II endometrial carcinoma to determine the accuracy of intraoperative frozen section (IFS) diagnosis. The IFS diagnosis and the permanent section diagnosis were compared in myometrial invasion, cervical invasion, adnexal involvement, tumor differentiation, and histological types. In IFS diagnosis, deep myometrial invasion, poor histological type, poorly differentiated tumor, cervical invasion, and adnexal involvement were considered as high risk factors for the pelvic and the paraaortic nodal metastasis. The depth of myometrial invasion (superficial 1/2 vs deep 1/2) was accurately determined by IFS diagnosis in 44 of 45 cases (97.8%). The sensitivity was 93.3%, and the specificity was 96.8%. The following tumor characteristics were also accurately determined by frozen section at surgery: histologic types (91.1%), poorly differentiated tumor (95.6%), cervical invasion (91.1%), and adnexal involvement (100%). One case of deep myomerial invasion, four cases of cervical invasion, and two cases of poorly differentiated tumor were underestimated in IFS diagnosis. 15 of 20 patients (75%) were correctly identified by frozen section at surgery as having high risk for pelvic and paraaortic nodal metastasis. We conclude that IFS diagnosis is an important procedure that enables the surgeon to identify the patients at high risk for the pelvic and the paraaortic nodal metastasis.

일제강점기 동해 어족 자원의 수탈과 활용

심재욱,하원호 숭실사학회 2017 숭실사학 Vol.0 No.38

일제 강점기 식민지 조선의 막대한 물적ㆍ인적 자원이 일제에 의해 수탈되었음은 잘 알려져 있다. 그런데 수산자원에 대한 수탈은 다수의 관련 연구 성과가 생산되었음에도, 아직도 쌀과 같은 토지 생산물에 대한 수탈에 비해 상대적으로 덜 알려져 있는 실정이다. 강점 이전부터 한반도 해역에서의 어업에 진출한 일본인들은 식민지 권력의 비호, 막대한 자본과 선진적인 漁撈 장비와 어획법을 바탕으로 식민지 수산업의 ‘주인’으로 자리 잡았고. 막대한 수산자원들을 수탈하였다. 일제가 수탈한 수산자원 중 대표적인 것은 바로 정어리이다. 1920년대 중반부터 활기를 띠기 시작한 정어리 어업은 1930년대 후반에 정점을 찍었다. 1937년에는 정어리 어업을 통해 거둔 막대한 어획고를 기반으로 세계 2위의 어획고를 차지할 정도였다. 여기에는 1910년대부터 40년대 초까지 동해 지역에 다량으로 回遊한 정어리 무리의 존재와 1910년대부터 본격적인 궤도에 올라선 일본의 유지공업의 발전이라는 공급과 수요가 상호보완적인 역할을 하고 있다. 당시 일본의 유지공업은 주로 牛脂을 기반으로 하였으나, 제1차 세계대전으로 인한 공급 부족과 가격 상승으로 인해 대체 원료를 찾게 되었다. 이때 주목을 받은 것이 바로 魚油를 기반으로 한 硬化油였고, 魚油 및 硬化油의 생산을 위해 풍부한 지방을 함유하고 있는 정어리가 대량으로 어획되게 되는 것이다. 한편 硬化油 가공공업은 군사적인 측면에서도 매우 중요하였다. 경화유 분해 과정에서 생성되는 글리세린이 바로 화약의 원료가 되기 때문이었다. 1935년 당시 소비된 글리세린의 전체 양 중 절반에 가까운 43%가 다이나마이트 및 해군의 화약용으로 사용되었다. 이와 같은 일본 유지공업의 팽창은 식민지 공업화에도 영향을 주었다. 일본의 신흥 재벌인 日窒콘체른에 의해 朝鮮窒素肥料株式會社, 朝鮮油脂株式會社 등이 설립되어 興南과 淸津에 공장을 건설하였다. 또한 이들 공장에 운영에 필요한 다량의 전기를 공급하기 위해 赴戰江 발전소와 같은 발전시설이 건설되었다. 즉 북한 일대를 주산지로 하는 鰮油業의 발전이 식민지 조선의 유지ㆍ화학공업 및 토목ㆍ전기 산업 발전의 모체를 이루게 되었다. 이러한 일본 자본의 침투는 식민지 권력의 군사산업 육성 정책과 맞물려 진행된 것으로 식민 조선의 공업에 새로운 계기를 이루었다. Exploitation of enormous amounts of material and human resources suffered by the Colonial Choseon during the Japanese Colonial era is a well known fact. However, despite multiple research results related to the exploitation of fishery resources, it is relatively less known compared to the exploitation of land products such as rice. The Japanese who began fishing in the waters of the Korean peninsula prior to the occupation positioned themselves as the owners of the fishing industry in the new colony based on protection from the colonial power, vast amounts of capital, and advanced fishing equipment and techniques. They exploited enormous amounts of fishery resources. A representative fishery resource exploited by the Imperial Japanese is pilchard. The pilchard fishing industry that became active during the mid-1920s reached its peak at the end of the 1930s. Based on the vast catch made through the pilchard fishing in 1937, the fishing amount increased to as much as second place in the world. Here, the existence of vast spawning migration of pilchards in the East Sea region from 1910s to 1940s and the supply and demand from the full-scale development of Japanese oil and fat industry starting from 1910s have resulted in a complimentary reaction. Although the Japanese oil and fat industry at the time was based on beef tallow, an alternative source was needed due to the lack of supply and price hike after the World War I. One thing to note here is the hydrogenated oil based on fish oil, where large quantities of pilchards that contain rich sources of fat was fished to produce fish oil and hydrogenated oil. On the other hand, hydrogenated oil processing industry was also extremely important in terms of their military. This is because glycerin produced during the process of hydrogenated oil decomposition became the source of gunpowder. Almost half (43%) of the entire glycerin consumed in 1935 was used for dynamites and gunpowder for the navy. Such expansion of the Japanese oil and fat industry also influenced the industrialization of the Japanese colonies. With the establishment of Choseon Nitrogen Fertilizer Co., Ltd.(朝鮮窒素肥料株式會社) and Choseon Oil and Fat Co., Ltd.,(朝鮮油脂株式會社) etc., by the emerging Japanese conglomerate Nippon Chisso Konzern, factories were built in Heungnam(興南) and Chungjin(淸津). In addition, in order to supply large amounts of power required for the factories, power facilities such as Bujeon-River(赴戰江) Power Plant was constructed. In other words, the advancement of pilchard oil industry that used the whole North Korean region as its chief producing district became the parent institution of Colonial Choseon’s industrial development in the oil/chemical and civil/electric industries. Such penetration of Japanese capital progressed in line with policies on developing military strength in the colonies and led to new industrial opportunities in the Colonial Choseon.

SEMM방식에 의한 골반경 자궁적출술 (CISH) 의 임상적 경험 43 예

심재욱,김희수,손찬우,이승호,유은희,고창원,이기훈 대한산부인과학회 1994 Obstetrics & Gynecology Science Vol.37 No.11

본 연구결과 다음과 같은 결론을 얻었다. 1. 복구와 질에 절개선이 없고 실제적으로 복강을 열지 않고 Serrated-Edge Macro Morcellator를 이용하여 자궁을 제거하므로 환자에 대한 신체적 부담을 줄일 수 있으며 수술감염의 최소화가 가능하다. 2. 자궁경부의 편평-원주세포 연결부 및 자궁저부의 조직을 얻어 조직학적 검사와 판독을 할 수 있으며 자궁경부암 및 자궁내막암의 발생을 예방할 수 있다. 3. 수술후 자궁천골인대와 골반저부를 정상적으로 보존할 수 있으므로 회복이 빠르며 정상적인 사회생활로의 복귀를 촉진시킬 수 있다. Classical intrafascial SEMM hysterectomy (CISH) is a synthesis of cervical conization, supracervical amputation and operative laparoscopy to constitute a new type of hysterectomy compatible with the concept of minimally invasive and organ preserving surgery. We have experienced of 43 cases of CISH at Cheil General Hospital from November, 1992 to April, 1994. There were three cases where CISH was stopped and total abdominal hysterectomy was done because of the following reasons: the size of the uterus being too large to apply endoloop around the cervico-corporeal junction, severe pelvic adhesion and subcutaneous emphysema. The average age of patients was 43 years old. Indication were 17 cases of uterine myoma(42.5%), 15 cases of adenomyosis(37.5%), 5 cases of ovarian tumor(12.5%), 2 cases of abnormal uterine bleeding(5.0%) and 1 case of endometiral hyperplasia(2.5%). In size of uteri, 8 gestational weeks size was the most common, being 14 cases(35.0%), and the size of uteri varied from 6 to 12 gestational weeks. We have performed subtotal hysterectomy preserving the cervix whereas squamo-columnar junction and endocervical glands being revomed to prevent potentia occurrence of cervical cancer in future. The cervical shell connected by uterine ligaments was preserved to maintain the normal pelvic floor to minimize postoperative infection and to accelerate early recovery. Initially, the mean operation time was 310 minutes. With accumulation of operators experience it was reduced to 198 minutes. The hemoglobin was reduced by 1.66 gm/dl and the hematocrit by 4.57%. There were 2 cases of massive bleeding during operation and 3 cases of minimal cervical bleeding, 2 cases of dysuria, 1 case of febrile morbidity and 1 case of severe headache postoperatively. The average hospitalization was 6 days. The average days of return to domestic activity was 21.5 days. In conclusion, CISH was compatible with minimally invasive and organ preserving surgery and showed shorter operation time with subsequent quick recovery of patients and the reduction of complications. Moreover, hospitalization can be shortened. The important factors in maximizing these advantages of CISH were the experience of the operator, the size of the uterus, and the degree of the pelvic adhesion.

콩의 도복 (倒伏)에 영향하는 생육형질 및 유전 분석도복에 미치는 생육형질의 영향

심재욱,정남진 한국콩연구회 1991 韓國콩硏究會誌 Vol.8 No.1

多肥密植狀態에서 大豆의 倒伏에 영향하는 生育形質을 알아보기 위하여 倒伏程度가 상이한 10個 品種에 대하여 倒伏에 영향하는 콩의 主要生育形質을 調査分析한 結果는 다음과 같이 要約된다. 1. 콩의 倒伏은 開花期를 前後한 時期부터 일어나는데 각 品種에 있어서 倒伏程度는 開花期, 種實 肥大期 및 收穫期에 있어서 거의 同一한 反應을 보였다. 2. 콩의 主要生育形質들 중에서 倒伏과 關聯이 깊은 形質들은 主莖長, 莖直徑, 葉面積指數 分枝數 및 根乾物重이었는데 莖長, 分枝數 및 葉面積指數는 正의 相關을 나타내었고 莖直徑과 根乾物重은 負의 相關을 나타내었다. 3. 倒伏과 關聯이 깊은 形質들의 倒伏에 미치는 영향은 根乾物重을 除外한 모든 形質들이 開花期와 種實肥大期에 類似한 反應을 보였다. 4. 倒伏과 有意한 相關을 보이는 5個 生育形質을 대상으로한 經路係數分析에서 開花期는 分枝數가 그리고 種實肥大期에서는 葉面積指數와 分枝數가 倒伏에 크게 영향을 미쳤다. 5. 多肥密植條件에서 倒伏은 草冠內로의 透光量 減少에 의한 主莖의 徒章에 基因되는 것이 주된 원인으로 생각되었다.

오염지역과 비오염지역의 토양의 특성과 토양 미생물의 분포

오염지역과 비오염지역으로부터 채집한 토양에서 토양의 습도, 유기물의 함량, 토양산도 등 물리적인 특징과 토양미생물의 분포와 같은 생물학적인 특징이 조사되었다. 지역에 따른 유기물의 함량과 토양산도는 큰 차이를 나타내었으나, 식물군락에 의한 토양수분과 유기물 함량의 차이점은 발견할 수 없었다. 토양의 산도는 미생물의 분포수와 상관관계를 나타내었다. 이러한 것은 식물이 자라는 토양에 변이를 주는 것으로 산성비와 관련이 있는 것으로 추정된다. A total of 112 soil samples collected from polluted and unpolluted areas in Korea were investigated for physical properities (such as soil moisture, organic matter and soil pH) and biological properties (such as microbial numbers). The results of organic matter and soil pH showed a great variation(p=0.01) in the four areas, whereas soil moisture and organic matter were similar among three plant vegetations. There was a significant relationship(p=0.01 or 0.05) between soil pH and microbial number These results imply some variations in soil environment and may lead to unfavorable changes of plant vegetation in soil. Presumably, the above results appear to be resulted from soil acidification caused by an acidic rain.
