Background The olive founder (Paralichthys olivaceus) is a saltwater fsh, which is valuable to the economy. The olive founder strives to adapt to environmental stressors through physiological, biochemical, and transcriptional responses. The rise in water temperature threatens the growth, development, reproduction, and survival of olive founder. Each organ in the olive founder can diferentially respond to heat stress. Objectives The purpose of this study is to investigate organ-specifc transcriptional changes in olive founder tissues during heat stress. Methods In this study, transcriptome dynamics of the gill, liver, and muscle of olive founder to acute or chronic heat stress were investigated. Results Principal component analysis plotting revealed that the transcriptome of each organ is quite separated. K-means clustering, gene ontology, and Kyoto Encyclopedia of Genes and Genomes pathway analysis showed the diferential transcriptome responses of each organ to heat stress. Heat stress commonly afects the pathways involved in the correct protein folding, DNA repair, and cell cycle. Conclusion Our results may provide a valuable molecular basis of heat acclimation in fshes.

Purpose and Method: To access the value and results of femoro-femoral bypass for the treatment of unilateral iliac artery occlusion, the clinical data of 53 patients who underwent femoro-femoral bypass graft at Yeungnam University Hospital between January 1994 to December 2000 were analyzed retrospectively. The influence of variables (such as, age, sex, preoperative symptom, risk factors and associated medical illness, status distal artery, preoperative ABI) on the long term patency was evaluated by univariate statistical analysis. Result: The patients were 47 males and 6 females ranging from 37 to 84 years of age. The mean age was 65, with the highest incidence among people in their 60s, followed by those in their 70s and then in their 50s. Associated disease were hypertension in 28 case (52.8%), diabetes mellitus in 10 cases (18.8%), cardiac disease in 19 cases (32.0%) and cerebrovascular disease in 4 cases (7.5%). History of smoking was noted in 77.4% of the cases. Focal stenosis of donor site iliac artery has been found in 2 cases and combined distal outflow occlusion has been found in 21 cases, 2 donor site iliac artery ballon angioplasty was performed preoperatively and 14 adjuvant procedures (9 femoro-popliteal bypas, 2 femoro-tibial bypass, 3 profundoplasty) was performed simultaneously during the operation. Cumulative 1,3,5,-year primary and secondary patency rates of all femoro-femoral bypass were 87.0%, 76.6%, 68.1% and 91.7%, 85.7%, 73.5%. There was no operative mortality and major perioperative complications. Univariate analysis showed that the patients without distal arterial occlusion had significantly better 1-, 3-, and 5-year primary patency rates (93.0%, 89.0% and 74.2% versus 76.6%, 45.9% and 45.9% and 45.9%, P=0.02) compared with the patients with distal arterial occlusion. No significant effect was exerted by all other variables on long term results. Conclusion: These results suggest that femoro-femoral bypass is a sate and durable operation that results in good patency in a good runoff.

본 논문에서는 기존의 세탁조와 전동기 사이 기계적인 기어 및 벨트를 이용하여 전동기의 토크를 전달해 세탁하는 간접 구동방식이 아닌 세탁기의 저소음화를 위한 기어 및 벨트를 제거한 직접 구동방식의 외전형 SRM을 설계하였다. 세탁기에서 저속 고토크 특성을 가지는 세탁모드와 고속 저토크인 탈수모드를 모두 만족하는 넓은 가변속 범위 특성을 가지는 외전형 SRM을 설계하고 FEM 특성을 해석하였으며, 제안된 12/8 외전형 SRM이 드럼세탁기의 직접 구동 전동기로 사용될 수 있는 가능성을 확인하였다.

To examine soil erosion phenomena by freeze-thaw mechanism, soil moisture, underground soil temperature, soil hardness, and air temperature were investigated during two successive winter seasons(Jan. 16-Mar. 25, 1988 and Dec. 15, 1988-Mar. 20, 1989) for the designed cut slopes at the Colleage of Agriculture, Seoul National University, Suwon, Korea. The results of this study should be summarized as follows; 1. Soil moisture of northern slope was higher than that of southern slope. 2. Soil hardness during the freezing-thawing period was higher than during the thawing period. Mean soil hardness of the northern slope (18.84, 18.12㎏/㎠) was higher than that of southern slope (4.59, 4.32㎏/㎠) during the freezing-thawing period, but northern slope (1.00, 1.21㎏/㎠) had a lower value than southern slope (2.38, 2.24㎏/㎠) during the thawing period. 3. Mean amounts of soil erosion of the southern slope (8,703, 3,576㎤/㎡) during the examined periods were higher than those of northern slope (7,024, 2,693㎤/㎡). 4. Freeze-thaw erosion phenomena were influenced by soil moisture and variation of soil temperature. 5. From the results of this study the amount of soil erosion by freesz-thaw mechanism was greater at the southern slope than at the northen slope. It must be taken into consideration of lowering the gradient of southern slope than that of northern slope in designing a forest road.

The study emphasizes on the taxonomical characteristics, distributions and ecological sites, propagation methods and uses, and possibility and ranges of development of the woody climbers growing in the southern region of Korea. The woody climbers growing only in the southern region are 24 species having the evergreen climbers of 13 species. The suitable species for the environment conservation and revegetation on the denuded land in the southern region are Euonymus fortunei var. radicans Rehder., Hydrangea petiolaris S.et Z., Schizophragma hydrangeoides S et Z., and Elaeagnus glabra Thun., Elaeagnus maritima Koida, Hedera rhombea S. et Z., and Trachelospermum asiaticum var. intermedium Nakai. These 7 species could not be used for the same purpose in the middle part of Korea (mainly Seoul region) due to the cold-resistances. Such usable species in the middle part region as Parthenocissus tricuspidata, Wisteria Floribunda, Pueraria thunbergiana, and Celastrus orbiculatus are also useful in the southern region as well as above the 7 species

농학캠퍼스 구내에는 캠퍼스의 역사를 말해 주는 듯한 노거수들이 군데 군데 자라고 있다. 어느 노목은 노령으로 이게 그 본래의 웅장한 모습이 노쇄해 지는 감이 짙기도 하고, 또 어느 거수는 너무나도 높이 높이 자라서 그 나무 아래에서는 그 수간의 정점을 관찰할 수 없는 천하대장군격인 장승수도 있다. 기록에 보면 상록의 얼이 담긴 농학캠퍼스구내에서는 대체로 1907년경부터 수목이 식재되었다. 정문수위실의 뒤편에 자라는 상수리나무와 굴참나무, 그리고 그 옆에 서 있는 희화나무는 처음 심은 자리에서 그대로 자라왔다. 초창기에 심은 나무들은 리기다소나무, 양버즘나무, 아까시나무, 칠엽수, 신나무 등이다. 그밖에도 일본가래나무, 흑호도, 개서어나무 등은 초창기 심어 졌으나 지금은 없어져서 이 나무를 심어 주신 선배님들께 죄송하기 이를데 없다. 농학캠퍼스 중앙길 부근에 있는 노거수 미루나무는 1908년, 본관앞에 있는 이팝나무는 1926년에 조사한 바 그때 수고가 5m였다고 한다. 본관앞 숲속의 섬잣나무도 초창기에 심어진 노목이며, 운동장 남쪽 복판에 외롭게 남아있는 꽃개오동나무도 1907년에 들어온 나무 중의 하나로서 한때 황금수라는 이름으로 서둔동의 명물이 되어 서둔동을 카타루파(Catalpa)촌이라고 부르던 때도 있었다. 농대정문에서 육교에 이르는 대학로에도 카탈파가로수가 많이 심겨자라고 있었다. 「서울의 마로니에」는 아직도 보존되고 또 비석까지 세워졌지만 「수원의 카탈파」는 간곳이 없구나. 농대에서 농촌진흥청에 이르는 서둔길가에 남아 있는 개서어나무는 1907년에, 칠엽수 마로니에는 1908에 심은 것인데, 이미 그 모습이 사라진 것도 있고, 아직 남아 있는 것은 고생스럽게 살고 있다.

This study was accomplished to develop educational and scientific use measures of arboreta through investigation of plant conservation and establishment status of the arboreta in Korea. The results could be summarized as follows; 1. Some available data in relation with the establishment status, names of indigenous plants(especially endemic, extinct and valuable plants) and practical uses of Korean and some foreign arboreta were collected and analized. These data will be very useful in exchanging informations and improvement of management system among the arboreta in Korea. 2. In Korea, it is necessary that the united organization as the positional central level like the "Korean Union of Arboreta" should be instituted to wholly control the construction and management of arboretum and botanical garden in the whole country. 3. The existing status of arboreta in some national university should be improved, especially in increasing number of kinds (speies) of registered plants as well as facilities and utilities including office building, research laboratories, and green houses, etc., and also staffs for the management.

The third year's results on effects of surface fire on frest vegetations and soil properties were investigated in Mt.Gwanak, Kyunggi-do successively after the study of the first year's effects in the same place. Organic matters in soil had increased just after fire and whatsome decreased during 1 year after fire, and resulted in percentage that was less than unfired area in the third year after fire. The pH of subsoil was continuously increasing from just after fire till after 1 year, but decreased somewhat in the third year after fire. More exact classification into Increasers, Decreasers, Invaders and Neutral species was possible in the third year's study. According to comparison of similarities, the vegetational structure of the species at fired area has been gradually restoring to original state as time goes by.
