全尙根,陳鉉五 慶熙大學校 1995 論文集 Vol.24 No.-

Twenty Korean white pine(Pinus koraiensis) families were tested in Youngdong site. Family, Block, and Family×Block interaction were significant sources of variance for height and diameter growth of progenies. The average height and diameter were 315.79m, 63.3mm, respectively. Heritability estimates of height growth were higher than those of diameter growth. Estimates of individual and family heritability were 0.30, 0.59 in height growth, and 0.23, 0.56 in diameter one, respectively. Correlatioship between height and diameter growth was significantly high(r=0.799). When the top 10% of individuals or families were selected, the expected genetic gains for tree height and diameter growth were higher in the combined selection and the mass selection than in another selection methods.

全尙根,奏雄 慶熙大學校 1990 論文集 Vol.19 No.-

This study was carried out to investigate the variation and heritability of cotyledon with 120 half-sib families of Korean White Pine sampled from 7(A-G) different plots. Family was a significant source of variation(1% level) for the number and length of cotyledons. Number of cotyledons with family ranged from 5 to 18, and averaged 11.91±0.35. The CV value and contribution rate were 13.40% and 11.25%, respectively. Family means of length of cotyledons ranged from 21.6 to 69.3mm. CV=9.51%, and averaged 47.12±0.98mm. The contribution rate of family to cotyledon length variance was 26.47%. Family within site was a significant source of variation(1% level) in both two cotyledon characteristics. Site was a significant source of variation(1% level) in the number and length of cotyledon traits, however, contribution rate was low level of 1.28%, 0.95% respectively for number and length of cotyledons. Replication has no effects in the two traits. There was no significant relationship between number and length of cotyledon. Individual tree and family heritability for cotyledon number were 0.45 and 0.72 respectively those for cotyledon length were higher(h^2_I=1.07, h^2_F=0.88) than the former trait.

陳鉉五,全尙根 慶熙大學校 1994 論文集 Vol.23 No.-

The growth performance, stem characteristics, and nutrient status of trees were investigated in the forest established for Japanese cedar (Cryptomeria japonica) provenance test in Cheju island. Height, diameter, and volume growth of trees from Jeon-buk, Mutsu, Wakinozawa, Tsuruoka, Muikamachi, and Yuri provenance were showed low productivity. When the trees of provenance showing better growth Mutsu, and Wakinozawa provenance were early growing type but those of other provenances were late growing type in incipient growth stage. The amounts of exchangeable Ca, Mg, and Na of this forest soil were in the ratios 5:2:1 so that this forest showed low productivity. When the trees of provenance showing better growth were selected, increment of about 4 to 5 in height could be expected. The concentrations of N, P, K, Ca, and Mg of the needles from trees showing different growth by provenances did not have any influence on informations for understanding the relationship between growth and nutrient status. According to the principal component analysis, branch thickness, clear length ratio, tapering grade, eccentric grade, and basic density were major variable traits for the stem over all provenances, but, only one provenance, Nishitsugaru was good on all these characteristics. The provenance Jeon-buk showed the best growth and moderate stem characteristics. The best Nishitsugaru provenance for stem characteristics showed low concentrations of Mg, Ca, P in the needles but those of the Tsuruoka provenance did not show the same trends. the concentration of Mg and P of Jeon-buk provenance was high, while that of Ca showed the trend to be low.

낭종성 부갑상선 선종과 심한 골병변을 동반한 부갑상선 기능항진증은 매우 드문 질환으로서, 저자들은 양측 고관절의 통증을 초기 주소로 내원한 환자에서 고칼슘혈증과 부갑상선 호르몬 증가, 골병변의 방사선적 소견을 통해 부갑상선 기능항진증을 진단하고, 경부 초음파와 컴퓨터 단층 촬영, 부갑상선 스캔검사 및 수술중 부갑상선 낭종액 검사 등을 통해 기능성 부갑상선 낭종의 한 종류인 낭종성 부갑상선 선종을 진단하고 수술적 제거를 통하여 정상화된 1예를 경험하였다. A cystic parathyroid adenoma is rare. A case of primary hyperparathyroidism, with the cystic formation of a parathyroid adenoma and a severe bony lesion, is reported. A 52-year-old male was admitted due to pain in both hips and for evaluation of hypercalcemia. The plasma level of the intact parathyroid hormone (iPTH) was elevated to 1424 pg/mL. Ultrasonography and the computed tomography revealed a parathyroid cyst on the left thyroid lower pole. Parathyroid scintigraphy detected a parathyroid adenoma. A radiograph showed a subperiosteal bone resorption on the phalanges, and a brown tumor (osteitis fibrosa cystica) on the femur shaft was noted. A surgical excision of the parathyroid adenoma was performed. The PTH level in the cystic fluid was increased. A histological examination confirmed a cystic parathyroid adenoma. The PTH level was normalized after the operation (J Kor SOC Endocrinol 18:214-220, 2003).

폴리아크릴로니트릴(PAN)과 세그먼트형 폴리우레탄(PU)과의 용액 blend를 DMF 용제하에제하에서 제조하였다. SEM으로 확인한 blend의 모폴로지는 입자분산형의 심한 상분리를 보이고 있으며, PU 분산상 입자는 변형된 형태로 나타난 반면, PAN 분산상 입자는 뚜렷한 구정형태로 나타났다. 동적점탄성 시험에서 PU의 tanδ peak는 저온으로 이동하였으며, 인장강도는 additivity rule에 대하여 약한 negative deviation을 보였다. FT-IR spectra에서 PU중 polyol unit의 carbonyl peak는 PAN이 첨가될수록 높은 주파수 영역으로 이동하였다. Blends of polyacrylonitrile(PAN) with ester type of segmented polyurethane(PU) were prepared in N, N'-dimethylformamide. Blends from SEM observation showed large phase separation in spherical domains. Dispersed particles of PU were deformed by shear force, while particles of PAN were distinct spheres. Tanδ peak of PU, determined from a rheovibron, moved toward lower temperature in blends. In addition, the tensile strength of blend showed slightly negative deviation against additive rule. In FT-IR spectra, carbonyl stretching peak of polyol units of PU moved toward high frequency with content of PAN.

Two experiments were carried out to get information about differences of fatty acid composition based on the sex of the Han-Woo tattles. Exp.1 14 females, 6 steers, and 10 males were used to determine the fatty acid composition of subcutaneous and perirenal fat. In composition of subcutaneous and perirenal fat, the contents of Palmitoleic acid(C_(18:1)) and Stearic acid(C_(18)) were signifinicant at the level of 5% by sex, but the others were not significant. On subcutaneous between the 12th and the 13th rib, females were higher than steers and bulls in the content of Palmitoleic acid(C_(16:1). However, on the content of Stearic acid, females were lower than steers and bulls by 5% significance level. Differences were not existed in the content of total unsaturated fatty acid. Fatty acid contents between the 6-7th rib and the 12-13th rib were similar. In location of subcutaneous fats, there were no differences by sex in the location of subcutaneous fats Exp.2 Five females of the Han-Woo cattles slaughted in Eun Yang slaughter house were used to determine the fatty acid composition of body fat. The results were as follow: Each fatty acid contents in subcutaneous fats were C_(16): 23.6%, C_(18): 7.4%, C_(18:1): 54.4%, TUFA: 62.5%, and C_(16): 24.0%, C_(18): 26.4%, C_(18:1): 43.6%, TUFA: 46.1% in perirenal fats. Comparing with two experiments, Exp. 2 was higher than Exp. 1 in Palmitoleic acid and TUFA contents, but not significantly. In case of the contents of fatty acid in the Han-Woo body fat were lower than those of Japanese Wagyu. In conclusion, it is necessary to improve the fatty acid composition of the Han Woo cattle. At the same time, the selection of sire and improvement of the feeding technique for the Han Woo cattle are urgently necessary.

The effect of pulse current parameters on the composition and preferred orientation of Sn-Ni alloy electrodeposits was studied. The cathode current efficiency of P.C. electrolysis decreased with the increase of mean current density and off-time and was lower than that of D.C. electrolysis condition. The tin content of the alloy electroplated in the bath of low Sn ratio(0.2) decreased with increasing mean current density, while the one of the alloy with high Sn ratio(0.5) increased. The tin content of alloy increased steadily with off-time. The preferred orientation of the alloy changed from (110)+ (101) or (110) to (002) or (101) with increasing peak current density for the alloy deposits plated from both the bath of low Sn ratio and the one of high Sn ratio respectively

This study has been conducted to offer as a reference material for follow-up research by other handball related researchers in this field study about handball. Knowing that the decision of the referees play a big role in the result of the game, we hope this study pave the way for future researchers, To achieve these goals, this study was selected with professional and amateur handball players as control group. The data were analized by One-way ANOVA and Multful regression using SPSS 11.0 for windows, This study resulted as the following : These decision of the referees differed according to the sex of the handball players. Female handball players showed a more positive attitude toward the referees decisions, Also, female and male handball players all thought the referees decision affect the result of the game but in particular, female players thought the referees were stricter than to male players, Meanwhile, according to the result of the survey of the relationship between the players awareness and experience, it turns out that the quality of the game resulted from the quality of the referees, After analyzing the awareness of players, tit was found that a crucial amount of the players consciousness was affected by the attitude of the referees. In this sense, handball players tend to become overly sensitive to the referees that, handball players. The analysis also represents the players consciousness to the referees but at the same time no findings proved that there is a certain impact on the result of the game. According to the results of this surrey, the handball players showed little confidence for the referees and this affects the result of the game. However when it comes to the impact of the referees on the game, the decision of the referees have consistency in making decisions of the game, and this has no actual affect on the result of the game. The reason these results come out is because it's a characteristic of handball but further analysis and theories should be made.

This study was conducted to investigate the effects of aerobic capacity on blood lactate changes after supramaximal progressive loaded exercise. The subjects were divided into Handball players(HB, n=6)group and Control(CT, n=6)group. All subjects exercised according to the protocol by bicycle erogometer. Blood lactate concentration was also measured during the test time. The RER values of CT group were relatively higher than that of HB group. In particular, the RER values of HR group at exercise 8 & 12min were significantly lower than that of CT group(P<0.05). The blood lactate concentration of HB group was significantly lower than that of CT group at 12min during the exercise(P<0.05). During the recovery times the blood lactate concentration of HB group were significantly lower than that of CT group. In addition, blood lactate clearance of HB group was also higher than that of CT group during the recovery time. From these results, it was suggested that lactate clearance during the supramaximal exercise may be affected by the level of endurance exercise performance.
