The exposure of blood to foreign materials can cause the denaturation of plasma protein components such as immunoglobulins and complements. And those phenomena increase the morbidity and mortality after intracardiac operations through the cardiopulmonary bypass. From April, 1987 to September, 1987, we had observed the serial changes of plasma total protein IgG, IgA, IgM, complements[C3, C4] in bubble oxygenator group[n=5] and membrane oxygenator group[n=5]. Statistically significant difference between two groups were present in total protein and C3. We conclude that using membrane oxygenator in long extracorporeal circulation can reduce the activation of alternative pathway of complement system, and which can reduce post-perfusion complications of the lung though we can`t prove it in mass populations.

This study explores the following research question to address issues linked to emotions, identity, and institutions: how has the cult (institution) of the three Kims affected North Koreans' strong sense of nationalism (emotion), which is based on their Juche ideology (identity)? This paper investigates four fundamental elements of historical institutionalism: time boundedness, path dependency, institutional changes, and the shadow of the past. First, time boundedness illustrates how culture and education have been used to build trust and loyalty in the general public to construct individual and family cults. Second, path dependence reveals how the Songbun system has resulted in strong nationalism throughout Rodongdang's institutionalization. Third, institutional changes highlight the significance of age divides, as different age groups do not always support the three Kims' cult. Finally, the shadow of the past helps us understand the primary processes for generating mass ardent nationalism in the form of powerful impulses for self-sacrifice.

Polypropylene(PP) is a textile material with various functions such as eco-friendliness, lightness, and elasticity. Although most synthetic fibers can be dyed and finished, but original PP is difficult to dye or finish due to its extremely hydrophobic properties, so its application expansion is limited. In order to solve this problem, dyeable PP was developed, and various researches on textiles for clothing such as mass production technology, fine fiberization and performance improvement are in progress. Plasma treatment is a processing method for modifying the surface of fabrics, and has effects such as hydrophilization, deepening color, improving adhesion, and surface polymerization. In this study, plasma treatment was applied to study changes in hydrophilization properties of dyeable PP, surface changes before and after plasma treatment and performance according to hydrophilization.

This study proposes an efficient weight training strategy to reduce body fat, by identifying the effects of weight training on body fat reductions based on individual characteristics and changes in skinfold thickness. We analyzed the effects of 12-weeks weight training on changes in skinfold thickness and the resulting body fat reductions by considering individual traits of the subject. Our results indicate that individual characteristics have no statistically significant effects on changes in skinfold thickness, but were statistically significant for changes in the amount of body fat. Second, changes in skinfold thickness showed statistically significant effects on changes in body fat. Third, weight training induced changes in skinfold thickness were more significant in men than in women. Men also exhibited greater changes in body fat than women after weight training. Taken together, these findings confirm that changes in skinfold thickness and body fat observed through the 12-week weight training had variations depending on individual characteristics, and changes in skinfold thickness significantly affect the changes in body fat. The weight training program proposed by this study considers incorporation of individual characteristics, rather than accomplishing the same outcome with uniform methods and amounts of training. Furthermore, this program induces changes in skinfold thickness before implementing random efforts for reducing body fat.

The purpose of this study was to investigate effects of changes in body composition due to combined exercise on balance of the 20' obese women. Based on voluntary participation, 21 obese women in twenties were randomly divided into : Control(no exercise, n=7), Group I (aerobic exercise 50 minutes, n=7), Group 2 (combined exercise 50 minutes, n=7). All groups conducted allocated program five times a week for six weeks. At post and pre-experiment and at the time of each measurement, changes of body composition and balance among the three groups were statistically analyed using SPSS 18.0 ver. Compared to pre-experiment, Group I, II showed decrease of weight and body fat rate, but Group II showed both increase of muscle mass and decrease of body mass index(p<0.05). In balance ability, Group II showed improvement of static and dynamic balance, meanwhile Group I showed only improvement of static balance. Therefore, this research showed that combined exercise had positive effects on balance by increasing muscle mass and changing body composition.

Rapeseed oil was stored under different conditions such as in the dark, with UV treatment, and with prooxidantscytochrome C and copper ion. The rapeseed oils stored at different temperatures were analyzed by a mass spectrometrybased electronic nose and discriminant function analysis (DFA). Volatile components in the rapeseed oil increased with storage time, and the discriminant function first score (DF1) moved from a positive position to a negative position as storage time increased. Changes in DF1 were higher under UV treatment than under the dark condition (DF1: $r^2$=0.9481, F=307.03). The different DF1 values (F1) under the dark condition were 0.099, 0.187, and 0.278 as storage temperature increased. The different values under UV treatment were 0.554, 0.588, and 0.542, as storage temperature increased from 4 to $26^{\circ}C$. As concentrations of prooxidants copper ion and cytochrome C increased, amounts of volatile components also increased. These were confirmed by DFA. Furthermore, changes in responses at each ion fragment agreed with reported results for GC/MS, which formed after rancidity of the oil, including pentane, pentanal, 1-pentanol, hexanal, n-octane, 2-hexenal, heptanal, 2-heptenal, decane, 2-octenal, undecane, and dodecane.

Objectives Previously, we demonstrated that a 5% ethanol extract of unripe Rubus coreanus (5-uRCK) and ellagic acid has hypocholesterolemic and antiobesity activity in high-fat diet-fed animals. Therefore, we conducted a clinical study on the anti-obesity effect of 5-uRCK in 140 Korean adults (aged 19-70 years, body mass index (BMI) ≥25 kg/m²). Methods The participants were randomly assigned to two groups and were administered the placebo (n=70) or 5-uRCK extract (800 mg, n=70) daily for 12 weeks. The subjects were instructed to maintain their usual dietary intake and normal physical activity. Anthropometrics, body composition (dual-energy X-ray absorptiometry), and blood parameters were compared between the two groups. Results Average body weight and BMI did not show any significant changes; however, changes in upper body fat mass between the two groups was significantly different, as determined using analysis of covariance adjusted for baseline of percent body fat and drinking units. Moreover, Although not significant, the trunk fat mass and percent trunk fat tended to decrease after 5-uRCK supplementation. There was no significant difference in other laboratory biomarkers between the two groups. All safety parameters were within normal ranges in the both group. Conclusions In the present study, 5-uRCK significantly reduced upper body fat in obese subjects after 12 weeks, which indicates that it may help improve android-type obesity. Furthermore, the supplement is safe and well tolerated.

Sarcopenia, characterized by a decline of skeletal muscle plus low muscle strength and/or physical performance, has emerged to be an important prognostic factor for advanced cancer patients. It is associated with poor performance status, toxicity from chemotherapy, and shorter time of tumor control. There is limited data about sarcopenia in cancer patients and associated factors. Moreover, the knowledge about the changes of muscle mass during chemotherapy and its impact to response and toxicity to chemotherapy is still lacking. This review aimed to provide understanding about sarcopenia and to emphasize its importance to cancer treatment.
