이철환,이경렬 진주여자전문대학 2002 論文集 Vol.25 No.-

This study is based on a 50cm Harvard Step Test of five male college students to find out the change of the blood contents in the period of convalescence after the maximum intensity exercise reaching 170 beats / minute of heart rate. We got these results after three experiments. 1. In the Period of Convalescence after the maximum intensity exercise, a white blood cell count was higher than that of normal period, and after 30 minutes of relaxing time it went back to normal range. 2. In the Period of Convalescence after the maximum intensity exercise, a red blood cell count was higher than that of normal period, and after 30 minutes of relaxing time it went back to the normal range. 3. In the Period of Convalescence after the maximum intensity exercise, a hemoglobin count was higher than that of normal period, and after 30 minutes of relaxing time it went back to the normal range. 4. In the Period of Convalescence after the maximum intensity exercise, a hematocrit count was higher than that of normal period, and after 30 minutes of relaxing time it went back to the normal range. 5. In the Period of Convalescence after the maximum intensity exercise, a platelet count was higher than that of normal period, and after 30 minutes of relaxing time it went back to the normal range. 6. In the Period of Convalescence after the maximum intensity exercise, a glucose level in the blood decreased slightly. But after 10 minutes of relaxing time, it went up to slightly higher level than that of a normal period. Even after 30 minutes of relaxing time, it did not fully recover to the normal period level.

Due to their unique living conditions and dietary habits, the Koreans` renal function model may be different from that of the Western people. About 40 years ago, a researcher reported that two thirds of the urine osmolality in Koreans was contributed by NaCl, while less than 1/3 by urea. It is known that the Koreans` daily consumption of NaCl is higher while their protein intake is lower, compared to that of the Westerners. Now-a-days, the Korean``s dietary habit is changing to a westernized life style. In this study, we investigated whether there were changes in urine composition and osmolality according to age. The subject of study were 215 Koreans (128 male, 142 female, age 7-68 years) living in the Chonbuk and Chonnam province in Korea. We performed routine physical examinations and analyses of the urine Na+, K+, Cl-, urea, NH3, creatinine, and osmolality on their 24 hour urine samples. In the case of the male, total body water, Na and Cl excretion, urine ammonia excretion were significantly changed between groups. In the case of the female, total body water and urine creatinine excretion were significantly changed between groups. We calculated the urine osmolar contribution of NaCl and urea. Our results showed that NaCl composed 63.6 % of total urine osmolality and Urea composed 36.4% of total urine osmolality. In conclusion, urine osmolar composition is similar to the 1960`s, but further studies are required to elucidate the change of urine composition in this population for another 50 years.

Lee, Chung-Yul,Lee, Gyu-Young,Jeon, Kyoung-Mi,Park, So-Hyun,Hong, Yoon-Mi,Lee, Hyeon-Kyeong Korean Society for Health Education and Promotion 2009 보건교육건강증진학회지 Vol.26 No.5

Objectives: The purpose of this study was to examine factors influencing stress coping behaviors of elementary students in Korea. Methods: This study used a descriptive comparative survey design. A total of 1,161 elementary students voluntarily participated in the study from 10 schools at three regional levels (large and medium-sized cities, and rural towns). Coping behaviors were measured by the modified Ways of Coping Checklist. The data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression. Results: The most commonly used stress coping behavior reported by the participants was mystic coping, followed by positive coping, and negative coping. Students living in the large city and female students tended to use more coping behaviors than students living in the medium-sized city or rural towns and male students, respectively. Positive coping behaviors were associated with high school performance while myotic coping behaviors were associated high life satisfaction. Conclusion: Elementary students who are males, dissatisfied with their lives, or living in large cities or rural towns tended to be at risk for poor coping. There were differences in factors influencing coping behaviors by type of coping behaviors. An approach to building a successful coping behavior that is specifically tailored to the gender subsets of population and region-specific social and physical environment is recommended. 목적: 본 연구는 한국 초등학생의 스트레스 대응행동에 관련된 요인들을 알아보기 위한 서술적 조사연구이다. 방법: 연구대상자는 세 개 지역(대도시, 중소도시, 농촌지역)의 10개 초등학교에서 자발적으로 참여한 5, 6학년 1,161명으로 자가보고식으로 설문이 이루어졌다. 스트레스 대응 행동은 수정된 Ways of Coping Checklist를 이용하여 측정되었다. 자료는 기술적 통계, t-test, ANOVA, 상관관계 분석, 다중회귀분석을 사용하여 분석되었다. 결과: 초등학생들이 가장 빈번하게 사용하는 스트레스 대응 행동은 신비적 대응($3.01{\pm}10.6$)이었고 긍정적 대응($2.61{\pm}0.72$)과 부정적 대응($2.01{\pm}0.72$)이 그 뒤를 이었다. 대도시에 사는 여학생이 중소도시나 농촌지역에 사는 남학생들보다 더 많은 대응 행동을 사용하였고, 신비적 대응행동이 높은 학업성적과 관련이 있었던 반면 긍정적 대응행동은 높은 삶의 만족도와 관련이 있었다. 결론: 초등학생의 성별, 삶의 만족도 수준, 지역, 학업성적과 스트레스 수준이 스트레스 대응 행동에 영향을 주었다. 또한 대응 행동의 종류에 따라 대응행동에 영향을 주는 요인들에 다소 차이를 보였다. 초등학생들이 직면하는 스트레스 상황에 대해 긍정적으로 대응할 수 있는 능력을 길러주기 위하여 대상자의 특성과 지역의 사회적, 물리적 환경을 고려한 중재프로그램 개발이 필요하다.

Most caterpillars, the larvae of butterflies and moths(Lepidoptera), are herbivorous. Sometimes they are regarded as serious agricultural pest that cause to damage agricultural produce, whereas some species such as Bombyx mori is known to be valued as sources of silk. Even though their major role in the ecosystem, details of biology are poorly known for most species. This study has been carried out to identify larvae and to acquire useful biological information of insect larvae through rearing from 1997 to 2014 in HECRI(Holoce Ecosystem Conservation Research Institution). From 2012 HECRI are carrying out ‘Larvae Identification and Specimen Security of Primary Endemic Moths in Korea Peninsula through Rearing’ supported by National Institute of Biological Resources(NIBR). Of these this study is the list about special caterpillars feeding on the foliage Willow Trees (Salix spp.) Total 143 species belonging to 13 families were collected and identified 69 species belonging to 12 families. Among them Willow Treesdependent monophagous caterpillars are 34 species belonging to 5 families, oligophagous 36 species belonging to 3 families and polyphagous 16 species belonging to 12 families. The dominant family is Geometridae(51 species), second is Noctuidae(35 species) and followed by Notodontidae(21 species).

Lee, Seung Woong,Song, Ja-Gyeong,Hwang, Byung Soon,Kim, Dae-Won,Lee, Yoon-Ju,Woo, E-Eum,Kim, Ji-Yul,Lee, In-Kyoung,Yun, Bong-Sik The Korean Society of Mycology 2014 Mycobiology Vol.42 No.2

We investigated a total of 335 samples of Korean native mushroom extracts as part of our lipoxygenase (LOX) inhibitor screening program. Among the mushroom-methanolic extracts we investigated, 35 exhibited an inhibitory activity greater than 30% against LOX at a concentration of 100 ${\mu}g/mL$. Especially, Collybia maculata, Tylopilus neofelleus, Strobilomyces confusus, Phellinus gilvus, P. linteus, P. baumii, and Inonotus mikadoi exhibited relatively potent LOX inhibitory activities of 73.3%, 51.6%, 52.4%, 66.7%, 59.5%, 100.0%, and 85.2%, respectively. Bioassay-guided fractionation led to the isolation of inoscavin A from the methanolic extract of P. baumii, which showed the most potent activity and was identified by spectroscopic methods. Specifically, inoscavin A exhibited potent LOX inhibitory activity with an $IC_{50}$ value of $6.8{\mu}M$.

The purpose of this study was to examine the effects of core exercises for female university students with scoliosis patients(Cobb’s angles ranging from ten to 15 degree) through a 15 week core exercise program, and the effects of the core exercise were further investigated by comparing those with doing individual core exercises and those with doing group core exercises. For the purpose, data was collected from 19 female M university students in C city. For 15 weeks, 9 female university students and 10 female university students had participated in individual core exercises and group core exercises respectively. Cervicothoracolumbar scenography was used to assess the effects of core exercises for scoliosis patients. Split plot Factorial Design and Repeated Measures ANOVA with three time points were conducted for data analysis using SPSS 19.0. Findings showed that group core exercises made significant improvements of Cobb’s angle symptoms both eight weeks and 15 weeks of measurement points, but individual core exercises showed a significant improvement of Cobb’s angle symptom only on 15 weeks of measurement point. These findings indicated that group core exercise programs are more efficient than individual core exercise programs. In the light of exercise adherence, theoretical and practical implications were provided in the discussion section.
