Objective : The writer has come to see that a study of the Theory of Ministerial Fire of JuDanGae presupposes a study of earlier theories of fire. Therefore, I have analyzed and studied the theories of fire presented by medical doctors since "Nae Gyeong(黃帝內經)" Method : To begin with, I have studied the concepts of grand fire(壯火) and small fire(少火), imperial fire(君火) and ministerial fire(相火) in "Nae Gyeong", and have construed the meaning of human fire(人火) and dragon fire(龍火) by Wang Bing(王冰), and fatty fire(膏火) by Sohn Sa-mak(孫思邈). Next, I have studied true fire(眞火) by Huh Sook-mi(許叔微) and true yang(眞陽) and pit fire(坎火) by Eom Yong-hwa(嚴用和), Theory on Right Kidney as the Gate of Life and Ministeiral Fire(右腎命門相火說) by Yu Wan-so(劉完素), and the reason why Jang Wan-so(張元素) asserted Theory of Three Burners as Ministerial Fire(三焦相火說). Result : I have understood the influence that the concepts of grand fire and small fire, imperial fire and ministerial fire in "Nae Gyeong"have exercised on the later medical doctors, and have also understood the physiological and pathological Fire that influences the human body. Moreover, I have seen that Fire, as discussed by scholars from Huh Sook-mi and Eom Yong-hwa to Yu Wan-so and Jang Wan-so, made great contribution to the later development of Theory of the Gate of Life, getting its entire picture in Eum Hwa. Conclusion : Seeing that the theories of Fire presented by medical doctors since "Nae Gyeong" and prior to JuDan-Gae had great influence on the later development of Theory of the Gate of Life, I have come to understand that along with Eum Hwa by Lee Dong-wan, they must precede a study of the Theory of Ministerial Fire of JuDan-Gae.

A female preference is a potentially complex function relating variation in multiple male traits with her probability of accepting the most optimal individuals as a mate. If mate preference is dominantly driven by additive fitness benefits, different females tend to be congruent in the decision of choice, whereas females will not necessarily share their mate preferences if non-additive benefits more strongly operate. Here, a sequential blocked design ($4{\times}4$) was applied to experimentally assess the relative contribution of additive and non-additive components to the female mate preference with Korean rosy bitterling, Rhodeus uyekii. In a total of 48 single stimulus presentations, behavioral elements of courtship activities were analyzed to derive the 'index of female preference'. Females showed a clear preference for males with more elaborate carotenoid colors, but mated randomly with respect to male body size and other color patterns. However, they were not individually consistent in their choice of mates, suggesting that non-additive components probably contribute to the evolution of female preference.

Ulmi radicis cortex is a herb medicine which has been used for the treatment of such allergic disease as urticaria, allergic rhinitis and athma. To assess the contribution of an aqueous extract of Ulmi radicis cortex(URC) in systemic anaphylaxis, we used compound 48/80 as a fatal anaphylaxis inducer in rats. URC inhibited anaphylactic shock 100% with a dose of 1.0 mg/g body weight (BW) 1 hr before injection of compound 48/80. URC significantly inhibited serum histamine levels induced by compound 48/80. URC (1.0 mg/g BW) also inhibited to 79.1% passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. URC dose-dependently inhibited the histamine release from the rat peritoneal mast cells (RPMC) by compound 48/80. Moreover, URC had a significant inhibitory effect on anti-DNP IgE-induced histamine release or tumor necrosis $factor-{\alpha}$ production from RPMC. The level of cAMP in RPMC, when URC was added, significantly increased compared with that of normal control. These results indicate that URC may possess strong antianaphylactic effect.

Success rate of transplantation of body organs improved due to development of medical equipment and diagnostic technology. In particular, a liver transplant due to liver dysfunction has increased. With the development of image processing and analysis to obtain the volume for liver transplantation have increased the accuracy and efficiency. In this thesis, we try to reconstruct the regions of the liver within three dimensional images using the mevislab tool, which is effective in quick comparison and analysis of various algorithms, and in expedient development of prototypes. Liver is divided by applying threshold values and region growing method to the original image, and by removing noise and unnecessary entities through morphology and region filling, and setting of areas of interest. It is deemed that high temporal efficiency, and presentation of diverse range of comparison and analysis module application methods through usage of MeVisLab would make contribution towards expanding of baseline of medical image processing researches.

Given the extensive role of IS in everyday life and the increasing presence of women in IS users, understanding gender differences in individual technology continuance usage decisions is an important issue. Nevertheless, much of the large body of research on gender differences has just examined mean differences between women and men in terms of abilities, usage habit, and traits. Even though lots of psychology studies have shown that women, more than men, were influenced by affective factors, gender-affection-continuance use linkage has not been examined in the context of on-line shopping services. Therefore, the primary purpose of this paper is to seek to examine gender differences in terms of influence of affective factor in the context of IS continuance use. Meanwhile, IS continuance has been an important subject of study in the IT research area. To date, to explain why and how users are motivated to continue to use on-line shopping services, lots of theory-based research such as expectation-confirmation model (ECM) has been proposed. In particular, various affective factors have been proposed to explain continuance use of on-line shopping services recently. Affective factors have been regarded as essential factors for increasing relational strength and satisfaction. Several affective factors have been studied by prior IS adoption and continuance studies. Among them are enjoyment and anxiety. In IS continuance research, positive affect has been commonly and narrowly conceptualized and measured as the enjoyment which a person derives from using computers. Hence, in this study, we introduced intimacy factor, which was conceptually related to the quality of interactions and relationships in previous research. It also has been regarded as essential factors for strengthening human relationships. As a result, we have observed gender effect while examining intimacy-continuance bond. As expected based on the previous literatures, women seem to be more sensitive in affective factors. The contribution point here is that we find evidence in the context of on-line shopping services.

Objectives: This study aimed to explain the health-related quality of life (HRQoL) gap between the poorest and the wealthiest quintiles in the capitals of Kermanshah and Kurdistan Provinces (Kermanshah and Sanandaj), in western Iran. Methods: This was a cross-sectional study conducted among 1772 adults. Data on socio-demographic characteristics, socioeconomic status (SES), lifestyle factors, body mass index, and HRQoL of participants were collected using a self-administered questionnaire. The slope and relative indices of inequality (SII and RII, respectively) were employed to examine socioeconomic inequality in poor HRQoL. Blinder-Oaxaca (BO) decomposition was used to quantify the contribution of explanatory variables to the gap in the prevalence of poor HRQoL between the wealthiest and the poorest groups. Results: The overall crude and age-adjusted prevalence of poor HRQoL among adults was 32.0 and 41.8%, respectively. The SII and RII indicated that poor HRQoL was mainly concentrated among individuals with lower SES. The absolute difference (%) in the prevalence of poor HRQoL between the highest and lowest SES groups was 28.4. The BO results indicated that 49.9% of the difference was explained by different distributions of age, smoking behavior, physical inactivity, chronic health conditions, and obesity between the highest and lowest SES groups, while the remaining half of the gap was explained by the response effect. Conclusions: We observed a pro-rich distribution of poor HRQoL among adults in the capitals of Kermanshah and Kurdistan Provinces. Policies and strategies aimed at preventing and reducing smoking, physical inactivity, chronic health conditions, and obesity among the poor may reduce the gap in poor HRQoL between the highest and lowest SES groups in Iran.

Computer simulation of the air flow over an automotive vehicle is now becoming a routine process in automotive industry to assess the aerodynamic characteristics of a medium-size vehicle such as $C_d\;and\;C_1$ and aslo to investigate the possibility of improving aerodynamic performance of the vehicle as a preliminary design for the production line. Mainly due to its contribution in saving time and cost in the development of new cars, computer simulation of the air flow over a vehicle is usually done well before a production car is introduced to the market and in gaining more and more attention as powerful computer resources are getting readily available nowadays. To aerodynamically design a car is mainly related with reducing a drag coefficient of car. A well designed car usually has a $C_d$ value in the range of $0.3{\sim}0.4$. It is understandable that automotive industry is rushing to reduce a drag coefficient as reducing even a small fraction of the $C_d$ value can have an enormous overall impact on many areas. Actually, the present research model was able to achieve a $C_d$ value in the range of $0.3{\sim}0.36$ for flow velocities of $60km/h{\sim}100km/h$ by strategically removing the possible factor hazardous to lower $C_d$ value. Prediction of the medium-size vehicle aerodynamics using CFD was performed when an actual car model was in the development stage and three-dimensional modeling was also performed to optimize it as the best model in terms of the best aerodynamic performance.

Aluminum extruded panels are widely used instead of corrugated steel panels for weight reduction in high-speed trains. Of the layers in the train body, it makes the largest contribution to the sound insulation. However, compared with that of a flat panel with the same weight, the TL of the aluminum extruded panel is remarkably lower in the local resonance frequency band. We study aluminum extruded panels for next-generation 400-km/h trains. We investigate the problem of sound insulation and propose a practical method to improve the sound-insulation performance. The local resonance frequency region is increased by a modification of the core structure, and urethane foam is placed in the core. The effect on the sound insulation is verified by experiments. Finally, the improvement for the entire sound-transmission loss is estimated for the layered floor panels of express trains.

The effects of organic Zn-L-selenomethionine (Zn-L-SeMet) at 0.3 ppm on carcass composition, meat characteristics, fatty acid composition, glutathione peroxidase activity, and ribonucleotide content were compared against the commercial inorganic sodium selenite (Na-Se) and the combination of the two, in commercial broilers. A total of 540 one day-old chicks were assigned at random to 3 dietary treatments : i) commercial inorganic selenium as control or T1, ii) a 1:1 ratio of inorganic and organic selenium as T2, and iii) organic selenium as T3. Carcass composition, meat characteristics, cholesterol content, fatty acid composition, and ribonucleotide content were generally unaffected by treatments. However, discrepancy were significantly observed in glutathione peroxidase activity (GSH-Px) and water holding capacity, with organic selenium showing higher glutathione peroxidase activity (p<0.01) and lower shrinkage loss (p<0.05), respectively. These findings could be explained by the contribution of organic selenium in bioavailability of GSH-Px. However, having conducted in a commercial close house system with sufficient amount of nutritional supplementation, the present study demonstrated little or no effects of organic Zn-L-SeMet on meat characteristics, fatty acid composition, and ribonucleotide content (flavor characteristic) in broiler chickens.

Background: Vitamin D has been suggested as one of the critical factors for female reproductive health with protective activities against different cancers but there are conflicting facts regarding its role on breast cancer without any clear data on premenopausal cases. This study aimed to evaluate the role of vitamin D from dietary sources and sunlight exposure on the incidence of premenopausal breast cancer. Materials and Methods: We conducted a case control study on 60 newly diagnosed premenopausal breast cancer patients and 116 normal women who lived in Sabzevar and surrounding villages in Razavi, Khorasan, a rural and conservative area of Iran. Results: The mean concentrations of 25-OH vitamin D in cases and controls were $15.2{\pm}8.15$ vs $15.5{\pm}7/45ng/ml$, both well below normal values elsewhere. In fact 50% of analyzed individuals showed very severe or severe vitamin D deficiency and the rest (25%) were detected in suboptimal levels. Although the lack of vitamin D and calcium supplementation increased slightly the risk of premenopausal breast cancer (p=0.009, OR=1.115, CI 95%=1.049-1.187), higher prevalence of weekly egg consumption (86.66% vs 96.55%, p=0.023, OR=0.232, CI 95% 0.065-0.806) showed a slight protective role. The last but the most important risk factor was lack of sunlight exposure because the breast cancer patients had total body coverage from sun (p=0.007, OR=10.131, CI 98% 0.314-78.102). Conclusion: This study pointed out the role of vitamin D and other possible risk factors on the development and growth of breast tumors in this special geographical region. Although this study has revealed the interactions between hormonal and environmental factors in this province of Iran, understanding the deficiency pattern and its contribution to other lifestyle factors elsewhere is also necessary.
