본 연구는 밤나무 교잡종 과실의 조합별 및 개체별 질적특성을 조사함으로써 신품종 육성의 기초 자료뿐만 아니라 품종검정 기준설정의 기초자료로 활용하는데 그 목적이 있다. 과실모양은 11 조합의 많은 개체에서 타원형(85.30%)을 나타냈으며 K×R 등 5조합에서 삼각형(3.78%), R×K 등 8조합에서 원형(5.46%), R×O 등 3조합에서 장타원형(5.46%)으로 각각 관찰되었다. 과피색은 모든 조합에서 암갈색과 적갈색이 각각 49.16%와 38.24%로 관찰되었으며 과피털은 K×R과 R×K만이 과피 전체에서 각각 1개체씩 관찰되었다. 과피털의 밀도는 대부분의 조합에서 92.86%가 중 이상이었으며 좌면의 크기는 E×O, E×R, K×O에서만 중 이상인 것으로 조사되었다. 과실의 광택은 K×O조합에서만 약인 개체가 출현하였으며 열과형태는 모든 조합에서 3가지 형태중 2가지 이상의 형태가 각각 혼재되어 있었다. 양적형질이 우수한 8개체 중 RO-22, RO-25 등 2개체만이 과실모양과 과피색이 각각 장타원형과 암갈색을 나타내었으며 OK-2 제외한 나머지 5개체는 각각 타원형과 적갈색으로 관찰되었다. 과피털의 위치는 OK-2 제외한 모든 개체는 과정부였으며 과피털의 밀도는 IO-15 제외한 모든 개체에서 밀하게 분포하였다. 좌면의 크기는 JO-7과 RO-25 개체가 가장 작았으며 광택은 K×O의 1개체를 제외한 모든 개체에서 중 이상으로 우수하였다. 열과형태는 JO-7과 JO-12, IO-15, OK-15 개체에서 각각 과정부 열과와 주두부 열과 등 각각 단일 형태를 나타낸 반면, OK-2 등 4개체는 과정부 열과와 측면부 열과가 혼재하고 있음을 알 수 있었다. 내피박피성을 조사한 결과, OK-2, OK- 4, OK-15 등 3개체는 내피박피율이 20% 내외로 불량한 반면 RO-25, JO-12 등 2개체의 내피박 피율이 각각 78.6%, 72.4%로 매우 우수한 것으로 나타났다. This study was aimed to applicate as the basic data for the presentation of International Union for the Protection of New Varieties of Plants (UPOV) guideline and for breeding new cultivars through qualitative characteristics of nut in chestnut hybrids. In nut shape, oval type, 85.30%, could be observed in all combinations, and triangle type, 3.78%, in K×R, K×O, E×R, I×R, J×O, and oblong type, 5.46%, in R×O, I×O, E×O, I×R, respectively. Both dark and reddish brown, 49.16% and 38.24%, in nut color were observed in all combinations, and nut pericarp hairs in only K×R, R×K could be observed in whole part. The density of its hair showed above middle rank (92.86%) in most of combinations, and the size of hilum area showed above middle rank in only E×O, K×O and E×R. Ten combinations except K×O showed a good condition in nut luster, and two or three types of three split type could be observed in all combinations, simultaneously. Superior individuals, RO-22 and RO-25, showed oblong and dark brown, but others except OK-2 showed oval and reddish brown in nut shape and nut color, respectively. In position of nut pericarp hair, only OK-2 showed stigma part, but all of superior individuals except IO-15 showed thickness in its density. Only JO-7 and RO-25 were smaller than others in size of hilum area, and JO-7, OK-4, OK-15, RO-22 and RO-25 had nuts with excellent luster. Most of individuals had nuts with two or three types in type of nut split, and JO-7, JO-12, IO-15 and OK-15 showed only single type. In peeling rate, OK-2, OK-4 and OK-15 showed around 20% while RO-25 and JO-12 showed 78.6% and 72.4% being considered as superior individuals for roasted chestnuts.

Background and Objectives : When p53 cancer suppressor gene, occurs gene deletion or point mutation, malignancy develops by loss of p53 function with abnormal p53 protein. The Epstein-Barr virus (EBV) is the causative agent of certain type of lymphoma and undifferentiated nasopharyngeal carcinoma. However, the role of EBV as a causative factor in other head &eck tumors is not fully elucidated except nasopharyngeal carcinoma. This study, the author examined that p53 expression and detection rate of EBV correlate to development of laryngeal and hypopharyngeal squamous cell carcinoma(SCC) and play the possible role of prognostic indicators. Materials and Methods : Formalin-fixed, paraffin-embedded tissue specimen from 32 cases of larynx and hypopharyngeal squamous cell carcinomas were studied by immunohistochemical staining for p53 and EBV. The results of analysis were compared with clinicopathological parameters. Results : p53 expression was 56.3% (18 cases) and the detection rate of EBV was 43.6% (14 cases) of 32 cases in laryngeal and hypopharyngeal squamous cell carcinomas. p53 expression was correlate with histologic grade (p<05) only. Detection of EBV was not correlate with clinicopathological parmeters. Conclusion : These results suggest p53 expression and the detection of EBV may be related with development of laryngeal and hypopharyngeal squamous cell carcinoma. And, the expression of p53 protein can be used as a prognosticator in laryngeal and hypopharyngeal squamous cell carcinoma under certain limitation.

We have usually experienced bone conduction impairment in chronic otitis media, but it is unclear that raised bone conduction threshold is due to the reflection of cochlear dam- age and / or Carhart effect ( an artificial elevation of bone conduction threshold due to conductive defect ) or both. The purpose of this study is to verify the influence of the artificial elevation of the bone conduction threshold in chronic otitis media and to estimate Carhart effect. A total of 336 cases of tympanoplasty with unilateral chronic otitis media without any other causes of sensorineural hearing loss was studied. The average threshold levels of the bone conduction in diseased ears ranged from 18.5dB at 4kHz to 12.1dB at 250Hz The longer duration of the disease, the larger perforation size, the more severe damage of the middle ear structure and the presence of the cholesteatoma made bone conduction threshold increased. The postoperative thresholds of bone conduction were Improved in 36 cases (40.4%) of the 89 cases that underwent operation with type I tympanoplasty technique without electrie drilling. The degree of the maximal improvement was 14.3dB at 2000Hz and the minimum was 8.8dB at 250Hz. but these result did differ from a statistically significant degree. The result suggest that the bone conduction threshold in chronic otitis media is elevated artificially by conductive defect and improved by successful reconstructive surgery.

목적 : 급성하벽심근경색증 환자에서 심전도상 흔히 동반되는 전흉부유도 ST절 하강의 의의를 알아보았다. 방법 : 심근경색후 24시간에서 48시간에 얻은 심전도를 기준으로 52명의 급성하벽심근경색증 환자를 전흉부유도에서 ST절의 하강이 있는 군과 없는 군으로 나누었으며 심도자, 관상동맥조영술, 심초음파도 및 방사성 핵종을 이용한 좌심구혈율 측정 등을 시행하였다. 결과 : 1) 좌심실확장기말압은 전흉부유도에서 ST절의 하강이 있는 경우에서 16.9±5.33mmHg로 없는 경우의 11.0±4.02mmHg보다 유의하게 높았다(p<0.05). 그러나 운동량 및 좌심구혈을은 흥부 유도상 ST절의 하강이 있는 경우 7.6±3.0 METs 및 53.9±9.1%로 없는 경우의 9.1±2.7 METs 및 54.6±9.5%보다 낮았으나 통계적 유의성은 없었다(p=0.180, p=0.823). 2) 관상동맥조영술상 전흉부 ST절의 하강이 동반된 군에서는 유의한 좌전하행지나 좌회선지의 협착이 있는 경우가 60.9% 및 57.9%로 ST절의 하강이 없는 군에서의 34.5% 및 7.7%와 비교해 좌관상동맥에 협착이 동반된 경우가 많았다(p=0.050, p=0.001). 3) 관상동맥조영술상 세 혈관질환의 빈도는 흉부유도상 ST절의 하강을 보인 23예에서 10예로 ST절 하강이 없었던 29예중 2예에 비하여 유의하게 많았고(P=0.007), 단 혈관질환의 빈도는 ST절의 하강을 보인 군에서 23예중 5예로 ST절 하강이 없었던 29예중 17예에 비하여 유의하게 적었다(P=0.002). 두 혈관질환의 경우에는 각각 8예와 10예로 양군간에 유의한 차이가 없었다. 4) 흉부유도상 ST절 하강의 빈도는 단 혈관질환 22예 중 5예에서, 두 혈관질환 18예중 8예, 세 혈관질환 12예 중 10예에서 관찰되어 협착이 있는 관상동맥의 수가 많을수록 ST절의 하강이 나타나는 빈도가 많음을 보였다(p=0.00308). 그러나 흉부유도상 나타난 ST절의 하강을 모두 합하여 구한 ST절 하강의 합은 협착이 있는 관상동맥의 수와 통계적인 유의성이 없었다. 5) 심초음파도상 좌심실 하벽의 벽운동은 ST절 하강을 보인 군에서는 akinesia가 83.3%, hypokinesia가 11.1%, 정상 벽운동이 5.6%로, ST절 하강이 없었던 군에서의 dyskinesia가 3.6%, akinesia가 39.3%, hypokinesia가 25.0%, 정상 벽운동이 32.1%와 비교하여 ST절의 하강이 있는 군에서 유의하게 벽운동의 장애가 빈번함을 보였다(p=0.03891). 그러나 좌심실전벽, 측벽 및 중격부위에서는 유의한 벽운동의 차이가 없었다. 결론 : 급성하벽심근경색증 환자의 전흉부유도에서 ST절의 하강이 동반되는 경우 다혈관 질환의 가능성이 높으며 좌심실확장기말압이 상승되었고 운동능력은 감소되어 있었다. 또한 심초음파도상 좌심실하벽의 벽운동장애도 심하였다. 따라서 전흉부 ST절의 하강을 동반한 급성하벽심근경색증 환자는 전흉부유도에 ST절 하강이 없는 경우보다 예후가 불량할 것으로 생각되며, 보다 적극적인 치료가 필요할 것으로 생각된다. The purpose of this study was to determine the significance of precordial ST segment depression appearing during acute inferior myocardial infarction and to assess the correlation of that with angiographic finding. 52 patients were allocated into two groups based on the existence of precordial ST segment depression : 23 patients with ST segment depression and 29 patients without ST segment depression. The extent of coronary artery disease as well as the prevalence of significant stenosis (≥70%) in left anterior descending artery were more frequent in patients showing precordial ST segment depression than in patients not showing them (p=0.050) and the result were similar in cases of left circumplex artery (p=0.001). On echocrdiographic examination of left ventricular (LV) wall motion, it showed more severely decreased inferior LV wall motion in patients showing precordial ST segment depression than in patients not showing them (p=0.03891) even though the other segment of LV wall motion didn't show the statistical difference between both groups. The other cardiac parameters such as LVEDP, exercise amount (METs) and ejection fraction were tend to showing bad profile in patients with precordial ST segment depression. From the above results, we could deduce that patients with precordial ST segment depression have relatively large infarction or concomitant left coronary artery disease, so they need more caution and intensive theraphy.

A study was made to estimate the economic level(Necon.) of mineral nitrogen and a proper cutting frequency for the dry matter production of Orchardgrass (Dactlyis glomerata L.) during the harvested years in 1993∼1995. Annual mineral nitrogen was applied at the levels of 0, 90, 180, 270 and 360 kg ha^(-1) in 3 cuttings, 0, 120, 240. 360 and 480 kg ha^(-1) in 4 cuttings, and 0. 150. 300. 450 and 600 kg ha^(-1) in 5 cuttings, respectively. The dry matter yields of all cutting frequencies in 1993 were significantly higher than in the other harvested years. Mean dry matter yield were 13.1, 12.7 and 14.3 tons ha-1 in 3, 4 and 5 cuttings, respectively. Higher efficiencies of dry matter production in response to mineral nitrogen application were recorded as 12.9 kg at level of 360 kg ha^(-1) yr-1 in 3 cuttings. 27.3 kg at level of 240 kg ha-1 yr^(-1) in 4 cuttings, and 20.5 kg at level of 150 kg ha-1 yr-1 in 5 cuttings, respectively. Significantly higher dry matter yields appeared as 4.6 tons ha-1 at 1st cut in 3 cuttings, 3.7 tons and 4.1 tons ha^(-1) at 2nd cut in 4 and 5 cuttings, respectively. The estimated marginal dry matter yields(Ymar.) were 11.7∼12.3 tons ha^(-1) at ranges of economic N level of 285.5∼316.6 kg ha^(-1) yr^(-1) in 3 cuttings, 10.4∼10.5 tons ha-1 at ranges of 176.7∼196.6 kg ha^(-1) yr^(-1) in 4 cuttings, and 11.2∼11.6 tons ha^(-1) at ranges of 246.1∼286.0 kg ha^(-1) yr^(-1) in 5 cuttings, respectively. Maximun dry matter yields(Ymax.) were 14.3 tons at the level of limiting N(Nmax.) of 379.5 kg ha^(-1) yr^(-1) in 3 cuttings. 11.1 ton at level of limiting N of 298.4 kg ha^(-1) yr^(-1) in 4 cuttings, and 12.3 ton at level of limiting N of 467.7 kg ha^(-1) yr^(-1) in 5 cuttings, respectively. Economic N level in all cuts were in the ranges of 85.1∼116.1 kg ha^(-1) cut^(-1) in 3 cuttings, 31.3∼69.7 kg ha^(-1) cut^(-1) in 4 cuttings, and 30.8∼81.4 kg ha^(-1) cut^(-1) in 5 cuttings, respectively.

綜合源別로 상수인 진주, 사천읍, 사천선진, 합천삼가의 경우와 우물물인 사천서진과 진주하대 등의 물과 上水源인 南江水의 分析結果를 要約하면 다음과 같다. 1. 給水源別로는 上水일 때가 硬度, 염소이온, KMnO_4 消費量, 蒸發殘留物이 우물물에 비하여 분석치가 낮은 傾向으로 나타났으나, 합천삼가물의 蒸發殘留物은 평균 226.7ppm으로 다소 높았다. 진주 상수, 사천읍 상수, 사천 선진 상수는 비슷하였다. 2. 우물물의 경우 蒸發殘留物 및 KMnO_4 消費量이 선진은 각각 395∼548ppm, 25.9∼28.1ppm으로 기준을 超過하여 飮料水로는 不適合하였고, 晋州 下台洞의 경우는 基準이내이나 周圍環境에 汚染을 받은것으로 보여지며 飮料水로 使用時 充分한 調査가 필요하다고 사료된다. 3. 上水源인 南江水는 本 調査 項目으로서는 異狀이 없는 것으로 判斷된다. This experiment was carried out in order to study the suitable water as drink with survice and well waters in Jinju area. At the same time, we consider that Nam river water is a raw water of service water. The results were as fallow: 1. Total hardness, chloride, consumption of potassium permanganate and total solid were low in service water than well, but total solid of Samga service water in Hapcheon was higher as 226.7ppm. The results appeared similarly in the other area except Hapcheon. 2. In case of well seonjin was determined higher (395∼548ppm) than 500ppm as total solid and higher (25.9∼28.1ppm) than 10ppm as conumption of potassium permanganate. Therefore it was not potable water. 3. The water of Nam river was not exceed the limits of low water quality stantard for service water.

Comoarative Analysis between the attack first and the counter attack The frequency of the attack first(1,905 times) in total kicking technique was more than that of counter attack(1,573 times) but the point of the attack first (188 points) was lower than that of the counter attack(256 points). Thus, the scoring rate of the counter attack(16.27) was higher than that of the attack first(9.87). The preceding study reported that all the kicking techniques were many used for counter attack but this study showed that Front turning kick and Hook kick were many used for the attack first, and that the players depended on the counter attack, for the counter attack was bettwe than the attack first in gaining points. 5. The result of kicking technique on each body section. The players can attack the face (high section) by all kicking techniques but the frequency of attacking the face was 731 times(21.02), that of attacking the body(middle section) was 2,747 times(78.98) of total frequency(3.478 times). Therefore, It showed that the players depended on body attack. The frequency of each kicking technique attacking the face(731 times) was as be-iow: (1) Hook kick: 196 times (2) Front turning kick:135 times (3) Front whipping kick:19 times (4) Back whipping kick:12 times (5) Back kick:7 times Total frequency of kicking technique attacking the body was 2,747 times, Front turning kick was 2,419 times and back was 328 times. Total point of all the games was 444 and the point gained by attacking the face was 110(24.77 of 100), the body was 334 (75.23 of 100) Total point gainde by attacking the face(110 points) in each kicking technique was as below: (1) Hook kick:61 points (2) Front turning kick:24 points (3) Front whipping kick:13 points (4) Back kick:6 points (5) Back whipping kick:6 points The point gained by attacking the body(middle section) was as Front turning kick:234 points, Back kick:100 points. Consequently, we concluded that attacking the body was the most effective in gaining points.

도시녹지의 대기환경개선 효과 : 서울시 중구를 중심으로;Focusing on Jung-gu in Seoul

조현길,조용현,안태원 江原大學校 附設 環境硏究所 2003 環境硏究 Vol.20 No.-

This study explored effects of urban greenspace on improving atmospheric environmcnt, which is concerned with CO₂, SO₂and NO₂ uptake, and with reduction of summer air temperatures. The site of this study was focused on Jung-gu in Seoul. Tree density and cover were1.1trecs/l00 m₂and 12.5% respectively for the study area except forest lands. Atmospheric purification by greenspace was associated with changes in tree cover per unit area of each land use type. The mean C02 storage by woody plants was 19.4t/ha, and annual uptake averaged 2.2t/ha/yr for C0₂, 1.9kg/ha/yr for SO₂and 5.0kg/ha/yr for NO₂. Entire tree plantings in the study area played a significant role by annually offsetting CO₂emissions of about 1,8301 from fossil fuel consumption by 330 persons, SO₂emissions of 1,620kg by 1,080 persons, and NO₂emissions of 4,230kg by 450 persons. The smnmer air temperature was 3.6℃ cooler at a location with 54% cover of woody plants and 4.5℃ cooler at a forest site with 100% cover, compared to a place with no planting. A 10% increase of woody plant cover was estimated to decrease slimmer air temperature by approximately 0.6℃ until a certain level of canopy cover. Analyzing data from the Automatic Weather Stations in Seoul revealed that increasing tree cover decreased mean air tern-perature for the smruner season (Jun∼Aug) in a nonlinear function. Woody plant cover was the best predictive variable of summer temperature reduction. The results from this study are expected to be useful in emphasizing the environmental benefits and importance of urban greenspace enlargement, and in urging the necessity for planting and management budgets.

The transfer matrix method is used to study the influence of the translational spring support on the transverse vibration of the simple curved beam. The translational spring supports are constituted by the middle point and the nine points at regular interval on the curved beam. The influence of the translational spring constants on the natural frequency of the simple curved beam is very much at 1st and 3rd mode and the natural frequency is augmented as increasing of the translational spring constants. Since the amplitude of the curved beam is small at high mode, the translational spring constant has a little influence on the transverse vibration of the simple curved beam. The simple curved beam supported elastically at middle point has high frequency than that supported elastically at nine points at regular interval. If the translational spring constant supporting the simple curved beam become very large, and then since the elastic support is similar to the rigid support, the transverse natural frequencies increase very much at the each mode of the simple curved beam.
