  • 본 연구는 비만 노인여성을 대상으로 아쿠아로빅 운동을 적용한 후 신체조성 및 혈중지질의 개선효과를 알아보고 노인운동프로그램에 관한 다각적인 기초자료를 제공하는데 목적이 있다. 실험참가자들 (n=31)은 12주 동안 주 3회 60분의 아쿠아로빅 운동을 Borg의 운동자각도 12-13의 강도로 실시하였다. 신체조성은 inbody의 생체전기저항분석법을 사용하여 측정하였고 채혈된 혈액에서 혈중지질 (고밀도지단백(HDL), 저밀도지단백(LDL), 중성지방(TG)와 총콜레스터롤(TC))을 분석하였다. 자료의 분석은 대응 t-test를 이용하였고 유의수준은 0.05로 설정하였다. 아쿠아로빅 운동 후 체지방량과 허리둘레는 유의하게 감소하였고 (p < 0.05) 혈중지질 중 LDL (p < 0.05), TG (p < 0.001), 그리고 TC (p < 0.05)은 유의하게 감소하였다. 이상과 같은 결과를 볼 때 아쿠아로빅 운동은 신체조성과 혈중지질에 긍정적인 방향으로 변화시켰으며, 지방대사의 활용을 높여 지질분해의 향상과 신체조성을 증진시키고 고지혈증의 위험성을 낮출 것으로 생각된다. 따라서 아쿠아로빅 운동이 지상에서의 유산소 운동 및 저항 운동을 대체할 수 있는 유용한 운동이라 할 수 있다.

  • Generally, paper multilayering was performed before wet pressing process. However, sheets whose characteristics are different could be put together at the dry state by adhesives for the specialty paper products. In this paper, potential adhesives such as PVAc, oxidised starch, latex, and PVA were chosen and multilayering of several sheets was performed in laboratory scale. The effects of base paper properties and the composition of adhesives on the physical properties of multilayering paper were investigated. Physical properties such as bonding strength and stiffness were measured. For the practical reasons, mill trial was also executed. According to the result of laboratory tests and mill trial test, the physical properties of multilayered paper were greatly affected by the composition of adhesives and it was found that PVAc showed the best performance in all its aspects among four adhesives. Oxidised starch had an advantage of high stiffness and PVA gave high bonding strength to the multilayered paper. And it was also found that the properties of base paper showed the great influences not only on multilayering process, but also on the physical properties of the multilayered paper.

  • [Purpose] The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the im-provement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function. [Methods] In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM). [Results] Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group. [Conclusion] These results suggest that the composition and timing of protein intake are more important than the total amount.

  • We evaluated the eating pattern, physical activity, and daytime sleepiness level in Chilean shift workers. Fifty, middle-aged adult health workers from a public hospital in Santiago, Chile, were included: a group undergoing shift work (shift workers, including at least one "night shift" and one "long day", n = 33), and day workers under traditional schedule (from 8:00 to 17:00h, n = 17). Body composition, physical activity, and daytime sleepiness levels, and diet characteristics (diet composition, meals' timing, and diet quality) were assessed. Despite similar total energy intake, shift worker showed lower carbohydrate (% of energy) and higher protein intake (both P < 0.01), decreased diet quality, an irregular eating pattern, and delayed meal timing (all P < 0.05). Physical activity and daytime sleepiness levels did not differ between groups. Findings from this first Chilean study in healthcare shift workers support the fact that meal timing and diet quality appear as critical factors for upcoming intervention studies in this group.

  • This study was performed to investigate the correlation between Premenstrual syndrome (PMS) and nutritional intake, blood composition of female students. One hundred and one female students were selected as the experimental subjects at Gyeongsang National University. To assess the PMS symptoms of the subjects, a questionnaire (PAP) score based on the methods of Halbreich, Endicor and Nee was prepared with 34 different items. Dietary survey was conducted by 24­hour recall method for 3 days and nutrient intakes were analyzed by the CAN-Pro. Blood composition of WBC, RBC, Hb, Hct, Ca and Mg was measured. The average height, weight and BMI of subjects were $160.7\pm4.6cm,\;54.1\pm5.7kg\;and\;21.2\pm1.9$, respectively. Average intakes of energy, calcium, iron, zinc, vit $B_2$, and folic acid per day were $1810.2\pm344.9kcal(90.5\%\;of\;RDA),\;621.1\;197.3mg(88.7\%\;of\;RDA),\;15.9\;pm4.9mg\;(99.3\%\;of\;RDA),\;8.1\pm3.4mg(80.5\%\;of\;RDA),\;1.1\pm0.6mg(88.3\%\;of\;RDA)\;and\;234.3\pm78.6{\mu}g(93.7\%\;of\;RDA)$, respectively. Score of the behavioral symptoms, psychologic symptoms, physical symptoms and other symptoms were recorded $1.79\pm0.86,\;2.11\pm1.08,\;2.31\pm1.11\;and\;1.58\pm0.86$, respectively. The relation between PMS and menstrual cramps was significant. A significant difference was observed for menstruation amount in physical symptoms (p<0.05) and other scores (p<0.05). The group who drinks alcohol over 30g per day showed higher scores at total PAP (p<0.05), psychologic symptoms (p<0.05), physical symptoms (p<0.05), and other scores (p<0.05) than those who don't drink alcohol. Calcium in the blood showed a negative correlation with total PAF score (p<0.05), behavioral symptoms (p<0.05), physical symptoms (p<0.05) and other scores (p<0.01). Magnesium in the blood showed a negative correlation with physical symptoms (p<0.05), other score (p<0.05). WBC was negatively associated with psychologic scores (p<0.05). Hb and Hct were negatively associated with other scores (p<0.05). In conclusion, calcium intake showed a level of $88.7\%$ of RDA and this study revealed that there is a correlation between PMS and blood composition in female college students. Therefore, calcium and magnesium supplements can be beneficial to relieve PMS symptoms.

  • In order to conduct research on oil originated in Mongolia for further application of petroleum not only as fuel but also as raw material for organic synthesis, we need to study the physical, chemical characteristics and individual, group hydrocarbon's compositions of main petroleum fractions. A number of studies and surveys on the physical and chemical characteristics, group hydrocarbon's composition of petroleum deposits in Zuun-Bayan, Sukhaibulag, Tsagaan Elst, Tamsagbulag have been carried out earlier through n-g-M, aniline point and dispersimetric methods successfully. Yet a detailed chromatographical and NMR spectroscopic study for the individual hydrocarbon's composition of Tamsagbulag oil main fractions has not been conducted. In the present study the results of GC analyses of gasoline fractions of wells 19-3, 19-13 and 19-10, Tamsagbulag (Eastern Mongolia) were presence. The gasoline fractions of given wells were characterized by the high concentration of paraffins and presence of trace amount of olefins. There were identified 69 paraffins, 45 naphthenes, 41 aromatics and 3 olefins in total 158 individual hydrocarbons from each samples of gasoline fraction. The first attempts to classify Tamsagbulag oil under the individual hydrocarbon's composition data were successfully conducted and the supposition of a genetic classification of given oil as "sapropelic" type was made.
