        10대 카누 선수의 철분영양상태 조사

        김정수,김선효,권용헌 한국운동과학회 2002 운동과학 Vol.11 No.2

        김정수, 김선효, 권용헌. 10대 카누선수의 철분영양상태 조사. 운동과학 제11권 제2호, 535-550, 2002. 이 연구는 남녀 중·고등학교 카누선수를 preseason 중에 18명, season 중에 12명을 대상으로 식이 조사와 혈액검사를 통해 카누 선수의 스포츠 빈혈 요인을 분석하였다. Preseason과 season 중 남녀 카누 선수의 평균 연령은 15.3세, 평균신장은 173.3㎝, 평균체중은 64.9㎏이었으며, 평균체질량 지수(BMI)는 21.7로 표준 체중에 속하였다. 식이 조사는 24시간 기억법(24-hour recall method)과 CAN프로그램(computer aided nutritional analysis program; 한국영양학회개발)을 이용하여 조사된 내용을 한국인 영양 권장량(Korean RDA)과 비교하였다. 혈청 철, 혈철 페리틴, TIBC, TS, 헤마토크리트 그리고 헤모글로빈 등 철 영양상태에 대해 분석하였다. 연구결과 식이를 통한 하루 영양소 섭취량은 preseason보다 season동안에 남녀 선수 모두 높았으며, 남자선수에 비해 여자선수의 철 섭취량이 양호하였다(p<0.05). Preseason 중에 철 섭취량은 권장량의 63.7%로 낮았으며, season 중에는 권장량의 93.6%로 권장량고 거의 유사하였다(p<0.01). 끼니별 영양소 섭취 비율에서 preseason과 season 동안 아침, 점심, 저녁식사와 간식을 통한 영양소 섭취 비율은 남자선수의 경우는 양호하였으나, 여자선수의 경우 아침식사를 통한 영양소 섭취비율이 낮고 간식을 통한 영양소 섭취비율이 높아 바람직하지 못하였다. Preseason과 season 동안 동물성 식품과 식물성 식품을 통한 철의 섭취 비율은 남녀 모두 식물성 식품에서 2/3정도 섭취하고 있어, 연구대상자의 철의 주요 급원은 식물성 식품으로 나타났다. 전체 대상자의 heme 철과 nonheme 철 섭취량은 preseason 보다 season 동안이 2배정도 높았으나(p<0.05), 가상적인 철 흡수율은 season에서 낮았다. 이는 preseason에 비해 season에서 철 유용도가 낮은 식사를 하는 비율이 높았기 때문으로 생각된다. 혈청 철 농도와 transferrin 포화도는 preseason 보다 season에서 높았으나(p<0.05), ferritin을 제외한 혈청 철 영양 상태 분석 지표는 두 기간간에 차이가 없고 대부분이 정상범위에 속해 있었다. Preseason과 season에서 전체 대상자의 혈청 ferritin 농도와 혈청 중의 다른 철 영양 상태를 나타내 주는 지표들간의 상관관계는 혈청 ferritin 농도와 혈청 TS간에는 유의적인 양의 상관관계가 있었으나(p<0.05), 다른 지표간에는 유의성이 나타나지 않았다. 빈혈 발생 요인은 preseason에서 혈청 ferritin 44.4%, 철 농도 50%, TS 44.4% 그리고 Hb 13.3%, Hct 6.7%로 나타났으며, season에서는 33.3%, 25.0%, 25.0% 그리고 8.3%, 8.3%로 각각 나타났다. 연구 대상자의 식이를 통한 철 섭취량은 preseason에서는 불량하고 season에는 양호하여, 두 기간간에 차이가 있어 철 영양섭취가 평소에 고르게 이루어지지 않고 있음을 보여주었다. 그러나 season의 경우에도 철 유용도를 높일 수 있는 MPF나 비타민 C의 섭취가 적절히 이루어지지 못해, 철 흡수율을 떨어뜨릴 수 있는 등 철 섭취의 질적인 문제도 인식할 수 있었다. 따라서 preseason과 season의 구분 없이 철의 양적, 질적인 섭취를 고려한 균형 잡힌 식사와 함께, 개개인의 체력에 맞는 적절한 운동량 조절이 이루어져야 할 것이다. 또한 남녀 대상자 모두 흡수율이 낮은 nonheme 철을 주로 섭취하고 있으므로 육류의 붉은 살코기, 가금류 및 생선류 등을 주로 섭취하고 철의 흡수율을 높이는 데에 기여하는 비타민 C의 섭취도 충분히 해야할 것이다. 아울러 운동선수의 합리적인 영양관리를 위한 영양교육과 체력에 맞는 운동조절이 함께 이루어져야 카누선수들의 빈혈 발생률을 줄일 수 있을 것이다. Kim, J. S., Kim, S. H. and Kwon, Y. H. A Study on the Nutrition Status of Iron among Teenage Canoe Players in Korea Exercise Science, 11(2): 535-550, 2002. This study was carried out to compare the nutrition status of iron(Fe) among teenage canoe players in Korea between the periods of preseason and season, based upon dietary nutrient intakes and serum indices of Fe nutrition status. Subjects were composed of 18 and 12 students including male and females, in preseason and season, respectively. Blood was collected for all subjects after 15 hour fasting in preseason and in season, respectively. Serum Fe concentration, ferritin concentration, total Fe binding capacity(TIBC), transferrin saturation(TS), hematocrit(Hct) and hemoglobin(Hb) values were determined. As a result, dietary nutrient intakes were lower in preseason than in season. Daily dietary Fe intake of subjects was 63.7% during preseason, and that was 93.6% of the Korean PDA during season; thus Fe intake was significantly lower in preseason than in season (p<0.01). However, apparently absorption ratio of Fe was higher in preseason than in season as food source of iron tended to be better in preseason than did in season. Serum Fe concentration and TS were significantly lower in preseason than in season (p<0.05), other indices of serum Fe nutrition status were not different between in two periods except serum ferritin. Serum ferritin and TS had significantly positive correlation in two period (p<0.05),respectively. For the prevalence of anemia in preseason, 44.4%, 50.0%, 44.4%, 13.3% and 6.7% by determining serum ferritin concentration, Fe concentration, transferrin saturation, Hb and Hot, respectively. In case of season, the prevalence of anemia evaluated by serum ferritin, Fe concentration, transferrin saturation, Hb and Hct was 33.3%, 25.0%, 25%, 8.3% and 8.3%, respectively. As a consequence, canoe players should increase the intakes of foods containing heme-Fe such as red lean meat and also increase intake of vitamin C as an increasing factor of bioavailability of vitamin C in order to prevent the sport anemia by enhancing the nutrition status of Fe, and they should manage their meals evenly through preseason and season.

        뇌 농양의 임상적 분석

        김정수,성연상,강재규,도종웅,정현태 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.3

        The authors reviewed 24 Patients with brain abscess from January 1986 to December 1990. The male to female ratio was 16:8 and most frequently developed at second decades. The commonest cause was chronic ear infection with abscess in the temporal lobe, and common organism was proteus species. All patients received a total of 6 weeks of antiobiotic therapy. Surgery was performed in 24 patients. Drainage of drainage and later capsulectomy may offer a simple, safe and easy removal of capsule. There was no postoperative death or empyema. The most important predictor of outcome was the patients condition when first seen. Early specialist care, computerized tomography, correct choice and dosage of antibiotics, and the surgical methods in present use should make this a benign disease.

      • 고교 축구선수의 운동스트레스 척도 개발

        김정수,윤영길 세명대학교 2000 世明論叢 Vol.8 No.-

        In a competitive sport situation, stress arise from multiple factors which were psychological, cultural and health problems, and causes poor performance. The purpose of this study was to develop a stress scale with reliability and validity for soccer player. participants were 464 high school male soccer players registered in the Korea Football Association(KFA). To generate initial stress items, 164 high school soccer players responded to an open-ended questionnaire regarding stress situation as a soccer player. Inductive content analysis of the responses resulted in 946 cases and 794 cases of stress situations for high school soccer players, respectively. The data were grouped into 57themes (high school) regarding specific stress domain. specific domains were categorized into 10 more general domains. Drawing on the results of the content analysis, 66 stress items for high school soccer player were generated. In the pilot study stage, 85 high school soccer players were completed the preliminary version. based on the results of factor analysis and reliability, 41 items for high school soccer player on stress were adopted for further item refinement. In the main study, 215 high school soccer players completed the 41-item versions, respectively. Confirmatory factor analysis, reliability, item correlation, and item analysis were used. The results of the analysis lead to 6-factor 24-item stress scale high school soccer players soccer players. The scale contains six stress-specific sub scale; undue oppression by a senior, restricted private life, dissatisfaction with soccer skills, dissatisfaction with coachability, career concern, and unfairness of a game. Using qualitative and quantitative approaches, this study developed measures to assess device and unique sources of stress which reflect cultural trait on korean school sport. Future studies should (a)focus on further validation of the measures, (b)examine relationship between sources and others stress sources and personal character, and (c)examine relationship between stress psychological factors.

        An Experimental Investigation of Parallelism Conditions on Right Peripheral Ellipsis in Korean

        김정수,박상희 한국언어학회 2021 언어 Vol.46 No.1

        This study presents experimental results on parallelism conditions between the remnants and their correlates in Right Peripheral Ellipsis (RPE) in Korean. Using acceptability judgment tasks, we tested whether and to what extent case and word order mismatches affect acceptability of RPE sentences. Results show that violations of parallelism due to case and word order mismatches lower acceptability of RPE sentences in a similar manner and that these violation effects are gradient rather than binary (Experiment 1). Results also show that, overall, RPE sentences are judged as less acceptable than their full coordination counterparts, but this acceptability contrast was significantly greater in the context of parallelism violation, indicating that RPE sentences are more sensitive to parallelism than full coordination sentences (Experiment 2). Taken together, these results provide evidence against the general ‘binary view’ held in previous research on RPE, which predicts either complete acceptability or complete unacceptability in case of parallelism violation. The marginality and cumulativity of parallelism violations suggest that parallelism in RPE is a gradient phenomenon and is better accounted for in terms of ‘soft’ constraints than formal constraints.

      • Eugene O'Neill의 주요 극작품 연구

        金正洙 부산 외국어 대학교 1998 外大論叢 Vol.18 No.1

        This thesis is to examine the plays of Eugene O'Neill in the view of Jungian psychology. Although O'Neill wrote various kinds of plays, he specially attempted to express psychology of human being strongly in the three plays, The Emperor Jones, Desire Under the Elms, and The Great God Brown. Through his life, O'Neill has been interested in the inner man and the duality of human character. O'Neill's major concern was to explore the human psyche and its motive. This is from the struggle to understand his own life and his inner self. In this sense the psychological approach is the best way to understand his three plays. O'Neill's insight into man's inner world coincide with that of Jung in many respects for he was influenced greatly by the writings of Jung. In the process of dramatizing man's inner world, O'Neill draws heavily upon various Jungian archetypes. O'Neill delineated protagonist's inner struggle by their mask. Thus, in putting man's inner world into his dramas, O'Neill borrowed his central metaphors from archetypal images burried in the unconscious mind of humanity - the dramatization of the very concept of Jungian psychology. This is why his plays are great literature which receives a responsive chord from all men.
