The current study was conducted to investigate (1) the duration of cambial activity and (2) the effect of degree days on the initiation of cambial activity of the Pinus koraiensis (PK) and Chamaecy- paris picifera (CP) planted in Mt. Worak. In addition, the differences of the seasonal cambial activities according to the diameter were also investigated using C. picifera with a diameter of 30 cm (CPL) and 15 cm (CPS), which were planted in the same year. The cambium samples were weekly collected using a mini-borer (Ø 2 mm), so called Traphor, between April and October in 2017. The results obtained are as follow. The initiation of the cambial activity of CP (April 21-28) were slightly earlier than PK (April 21). The species with the longest cambial activity was CPS (147.2±12.1 days), followed by PK (141.6±9.8 days) and CPL (139±12.1 days). The degree days inducing the initiation of the cambial activ- ity for PK and CP were 180.5 and 180.5-242.8, respectively.

Objective : The unprivileged children without lunch(UCWL) has been being markedly increased and becoming one of the social problem in Korea. This study was performed to assist the development of efficient support program through the investigation of the status and characteristics of the UCWL. Methods and Material : Subjects were 104 students sho were receiving the meal aid from the six social welfare facilities and 110 ordinary students of an elementary school in Pusan area. Questionnaire survey was conducted from February to March, 2001. Data was analyzed using SPSS program(ver 10.0). Results : There was no difference in gender and school years' distribution. The phenomenon of family deficient, instability of parents' job, unsatisfaction to the home's atmosphere, ill adaptation to their school life, and be alienated from their colleague were more frequent in UCWL(p<0.05). Impulse of runaway from home and suicide showed no difference, however, the present worries, preference of way for assist showed differences(p<0.05), The majority(88%) of UCWL has been giving the meal and less than on year. The most common way was food stuff(76%) and financial support for school meal program(73%), while the most preferred way was financial support for everyday life(43%). Conclusion : UCWL satisfied and gave thankful mind to the present supports, however, showed negative aspects - like emotional unstability and difficulties in their school life. Therefore, it thought to be needed the touch on the emotional aspects, not only on the formal and economic aids.

Twelve male students (major in physical education; non-coffee drinkers; 6 endurance athletes; 6 non-athletes) were studied to determine the effects of caffeine, and Glucose feedings on submaximal endurance performance. Each subject performed three submaximal cycling trials at an absolute intensity of 900kpm. The trials were randomized to negate any possible order or training effects. For the caffeine trial, 2.5 mg/kg body weight of caffeine in 250ml of artificially sweetened barley tea was ingested twice one hour and 30.min prior to the ride. In the glucose trial, 0.5g/kg. body weight of glucose in 250m1 of barley tea was ingested twice one hour and 30 min prior to the ride. During the control trial, 250ml of artificially sweetened barley tea was ingested twice one hour and 30 min prior to the ride. obtained data from the three trials were analyzed with one way ANOVA for repeated measures design. Significant differences between means were located using a multivariate comparison. The level of significance was established at p<0. 05. The results were summerized as follows : Ingestion of glucose elevated blood glucose and insulin levels at rest , but no significant differences in blood glucose concentration were found between the three trials . Glucose ingestion resulted in rapid hypoglycemia and inhibition of FFA mobilization during exercise. Caffeine ingestion increased significantly in VE, Vo2 and plasma osmolarity during the exercise. But caffeine ingestion failed to elevate plasma FFA concentration, HR and blood pressure significantly. Glucose or caffeine ingestion did not change in blood lactate, Hb , plasma Na+ concentration, Hit and RQ during exercise. In the above results, It was suggested that ingestion of caffeine prior to the exercise fail to increase in lipid metabolism during exorcise and may have some detrimental effects on endurance performance besides psychological ergogenic effect of caffeine, and that glucose ingestion prior to the exercise elevate blood glucose and insulin level at rest but may have detrimental effect of endurance performance because of rapid hypoglycemia caused by hyperinsulinemia.

This study investigates the fabrication of WC-12Co feedstock powders with weakly locculated slurries by spray drying under various conditions. The morphological defects and flocculation states according to the amount of additives are evaluated to prepare spherical WC-Co feedstock powders with little morphological defects and homogeneous microstructures. The characteristics of feedstock powders, heat treated between 850-1200℃, are analyzed via SEM, EPMA, and mercury porosimetry. The results showed that with the increase in heat treatment temperature the portion of larger pores around 10 μm increased while, that of smaller pores of 1 μm lessened due to the coalescence of WC particles, forming dense feedstock powders with little defects such as hollow or craters. The feedstock heat treated at 1200℃ showed a porosity of 42.2% and a density of 8.28 g/cm^(3) as well as uniform distribution of pores and Co. (Received January 19, 2004)

To evaluate usefulness of serum IgE to determine specific allergens, authors conducted priest IgE and MAST-CLA allergen-specific IgE assays in 78 allergic patients diagnosed at Soonchunhyang University Chunan Hospital during October 1998 through July 2000. During the study period, inhalent and food Korean panels were applied in 57 (73.1%) and 21 outpatients (26.9%), respectively. Kappa index was calculated to evaluate the agreement of priest IgE with Total IgE and allergen-specific IgE by MAST-CLA. 1. The men (±SD) age was 13.2 (±14.1) year-old and male accounted for 62.8%. 2. The overall positive rate of priest IgE was 66.7% and mean (±SD) level of priest IgE was 271.2 (±265.6) IU/ml 3. Patients with more than one specific allergen and with elevated total IgE by MAST-CLA were 25 (32.1%) and 33 (42.3%), respectively. 4. Significant agreement between total IgE and allergen-specific IgE was shown, but strength of agreement was slight (Kappa = 0.186, P = 0.046), 5. While no significant agreement between priest IgE and total IgE was observer, the priest IgE agreed significantly with allergen-specific IgE (Kappa = 0.153, P=0.043) In conclusion, our data suggested that serum priest IgE is more likely associated with allergen-specific IgE than total IgE in MAST-CLA assay. Furthermore, it is recommended that Korean panel of MAST-CLA should contain more specific allergens.

Arteriovenous fistula of uterus is a very rare cause of massive uterine bleeding. However, it is important to make a rapid and precise diagnosis when it does occur, because life-threatening massive vaginal bleeding may occasionally be a symptom of this disease. Uterine curettage or surgical trauma can cause vascular abnormalities, including pseudoaneurysms, acquired ateriovenous malformations, ateriovenous fistulas, and rupture of vessels. The diagnosis is made by angiography, and gray scale ultrasonography, color and duplex doppler ultrasonography, computed tomography, magnetic resonance imaging is helpful. Ultrasonography is the most commonly performed initial imaging examination for evaluation of abnormal uterine bleeding. Color and duplex Doppler US is an appropriate modality for the detection and diagnosis of uterine ateriovenous malformations and for follow-up after embolization. Transcatheter embolization has replaced hysterectomy as the treatment of choice in women wish to retain thier fertility. A case of arteriovenous malformation of the uterus which was diagnosed by ultrasonography. So reported this case with a brief review of the literature.

홍준희,박해용 한국스포츠심리학회 2002 한국스포츠심리학회지 Vol.13 No.2

본 연구는 경쟁불안이 강도와 방향으로 구분될 수 있음을 가정하고, 정서지능이 경쟁상태불안의 방향을 예측하는 예언변인으로 작용할 수 있음을 증명하는데 그 목적이 있다. 남·여 고교 양궁선수 115명을 대상으로 조사하였으며 조사 도구로는 방향차원이 부가된 경쟁상태불안 검사지(CSAI-2: Martens, Burton, Vealey, 1990)와 이수정과 이훈구(1997)의 TMMS(Trait Meta-Mood Scale: Salovey, Mayer, Goldman, Turvey, 및 Palfai, (1995)을 사용하였다. 자료처리는 경쟁상태불안(인지와 신체불안)의 강도와 방향 그리고 정서지능의 하위 차원인 정서명확, 정서주의, 정서개선의 평균과 표준편차를 산출하였고 각 변인간의 상관관계분석 및 중다회귀분석을 실시하였다. 그 결과 인지와 신체불안간에는 정적 상관, 강도와 방향간에는 부적 상관을 나타냈다. 정서지능이 경쟁상태불안의 방향차원을 더 잘 예측할 수 있는 변인임이 드러났고, 구체적으로 정서지능의 정서개선 요인이 경쟁상태불안 중 신체불안의 방향차원을 예측하는 변인이 될 수 있음을 증명하고 있다. 새로운 경쟁불안 척도 개발의 필요성과 체험정서와 표현정서간의 차이 등에 대해 논의하였다. The purpose of this study was to examine that emotion intelligence could predict the direction of competitive state anxiety in context to supposed that competitive state anxiety was divided into intensity and direction level. The subjects were 115 high school archery. CSAI-2 included the direction dimension(Jones & Swain, 1992) and TMMS(Salovey, Mayer, Goldman, Turvey, & Palfai, 1995) are administered to athletes one day prior to game. Results of correlation analysis and multiple regression analysis indicate that the direction of competitive state anxiety was statistically significant on the emotion intelligence, in particular, in the level of emotion improvement of emotion intelligence. Results support the hypothesis that emotion intelligence could predict the direction than intensity of competitive state anxiety. This results are discussed in terms of the concept of anxiety, applications in the field, and direction of study in the future.
