  • This study was perfomed to investigate causes of the senile hypotension, pathogenic mechanism, symptoms, and therapies through medical literatures, recent chinese medical literatures and chinese medical journals. The results are as follows ; 1. The senile hypotension has major symptoms of dizziness, weakness, syncope, palpitation, shortness of breath, and deficiency of Qi. Additionally, it has minor symtoms of letharhy, isomnia, tinnitus, amnesia etc... 2. The prodromal symptoms of Kwul and Kwul are relating to the symptoms of tachycardia, facial pallor, sweating, anxietas, ambiguous consciousness, and fainting. Weakness and dizziness due to deficiency make the symptoms of exhaustion, fatigue, vertigo, lethargy, and brachycardia. 3. The most principal cause of the senile hypotension is deficiency of Shen due to aging, congenital deficiency, and chronic illness. The rest of causes are defciency of Qi and blood, phlegm of retention, stagnation of Qi, blood stasis, blood prostration etc... In the view of the occidental meicine, the causes of the senile hypotension came from the reduction of cardiac output, the decretion of cardiovascular system's extention due to aging, hereditary factor, secondary factor due to exsanguination, diabetes mellitus, C.V.A etc..., and factor of neurogenic system's degeneration. 4. The principal pathogenic mechanisms are the insufficiency of Xing-Yang, the deficiency of Qi in middle jiao, and deficiency of Shen-Qi. The rest of mechanisms are the deficiency of both Qi and blood, stagnation of the Gan-Qi, and the deficiency of Gan and Shen. Zang-Pu Organs have something to do with Xing, Bi, and Shen. 5. As principal therapies, there are warming and recuperation the Xing-Yang, strengthing the middle-jiao and replenishing Qi, replenishing vital essence to tonify the Shen, and warming and recuperation the Shen-Yang. Additionally, the therapies of invigorating the Bi and relieving mental stress, strengthning the Bi and tonifing the Shen, invigorating Qi and nourishing Yin, soothing the Gan and regulating the circulation of Qi, and tonifing the Shen and nourishing the Gan help the cure of the senile hypotension. In prescriptions there are Baohe Yuan Tang, Buzhong Yigi Tang, Zuoguei Yin, Yougui Yin, Guipi Tang, Zhu Fu Tang, Shengmai San, Sini San, and Qi Ju Dihuang Wan. The medical herbs of Astragali Radix, Codonopsitis Pilosulae Radix, Ginseng Radix, Aconiti Tuber, Ephedrae Herba, Cinnamomi Ramulus, Cinnamomi Corfex Spissus, Zingiberis Rhizoma, Polygalae Radix, Liriopis Tuber, Polygonati Sibirici Rhifoma, Lycii Fructus, Schizandrae Fructus, and Glycyrrhizae Radix can be treated. 6. According to the clinical report, the principal causes are the deficiency of Qi, and insufficiency of Yang which symptoms are dizziness, vitality fatigue and acratia, amnesia, body cold and alger of extremity, spontaneous perspiration, and therady and weak pulse. It was improved by taking WenYang YiQi Tang, Zhu Fu Tang about 20-30 days. The improvement was shown on disappearance of subjective symptoms or the ascending of blood pressure to normal figure, and the rate of improvement was over 70%. 7. As regimens, taking warming and recuperating food(a sheep mutton, juglans regia, chiness date, longan aril etc...) and pungent food(chinese green onion, fress ginger, pipers fructns etc...), doing physical training, not being ill in bed at a long time, and preventing descent of blood pressure coming from sudden change of posture are needed. Additionally, the usage of diuretic, abirritant, and depressor needs to be extra cautious.

  • The purpose of this study was to find differences in evaluation criteria and to find differences in preferred images based on benefits segmented groups of jeans products consumers. Male and female Korean university students participated in the study. Quota sampling method was used to collect the data based on gender and a residential area of the respondents. Data from 492 questionnaires were used in the analysis. Factor analysis, Cronbach's alpha coefficient, cluster analysis, one-way ANOVA, and post-hoc test were conducted. As a result, respondents who seek multi-benefits considered aesthetic criteria(e.g., color, style, design, fit) and quality performance criteria(e.g., durability, ease of care, contractibility, flexibility) more importantly when evaluating and purchasing jeans products. Respondents who seek brand name considered extrinsic criteria(e.g., brand reputation, status symbol, country of origin, fashionability) more importantly than respondents who seek economic efciency. Respondents who seek multi-benefits such as attractiveness, fashion, individuality, and utility tend to prefer all the images: individual image, active image, sexual image, sophisticated image, and simple image when wearing jeans products. Respondents who seek fashion are likely to prefer individual image, and respondents who seek brand name more prefer both individual image and polished image. Mean while, respondents who seek economical efficiency less prefer sexual image and polished image.

  • I examined the archival basis of two historians who wrote history books with the same title of 'History'; Simaqian of ancient China and Herodotus of Halikarnassos. I examined a prejudice to these two history books, a misunderstanding of them as an imagination rather than a history. How can an imagination become a history? First, I explained the common characteristics found in their compilation and writing of 'History.' Simaqian and Herodotus did their field-works in historical sites, gathered oral-histories, and arranged archives they collected. These two historians heavily engaged in archival works in terms of verifying authenticity and reliability of their sources on the basis of historical empiricism. There are some misunderstanding on their archival endeavor and on the very nature of archives and historical studies as empirical studies. Furthermore, this misunderstanding regarding them as literature came from a confusion over the concept of literature. The creativity of literature is not equal to the "fictitiousness" of history despite historical works sometimes may give us an impression by the way of describing and providing insight into a certain event(s) and a person(s). As Herodotus said, a recognition of the differences of each race and human is a departure of historical archiving of the valuable experiences of human-beings. By doing so, natural results of archival behaviors, preservation of the records, and consistent inquiry of historian-archivists become a humanistic passage overcoming the current wrong trends of historical studies confined to a narrow nation-history.

  • Background: As life expectancy has been increased, the cardiac valve disease has been increased. In past, mechanical valve for valve replacement surgery was used widely, but it has many weaknesses, such as hemorrhage, teratogenic effect caused by warfarin, acute mechanical failure, taking warfarin during life, etc. So, the tissue valve is used widely and researches for durability of tissue valve are in progress. Tissue valves being used are all imported in Korea, and there is a lack of information on its geometry and design. So, we studied the geometry of porcine aortic and pulmonary valve, and tried to suggest theoretical basis for making the aortic and pulmonary valve. Material and Method: We harvested aortic and pulmonary valves of 25 pigs and measured the geometry of valve at fresh and glutaraldehyde (GA) fixed state. In each group, we measured the diameter of the base, diameter of commissure, valve height, commissural height, etc. Also, for making implantable porcine and bovine pericardial valve, we designed the valve stent form, thickness, height, and leaflet size, form, thickness by different size of valve. Result: The aortic and pulmonary valve geometry and ratio were measured in each group. The right coronary cusp of aortic valve and right facing cusp of pulmonary valve was bigger than other cusps and non coronary cusp was smaller than others (RCC: NCC : LCC=1 : 0.88 : 1). Valve height was correlated to the leaflet size. We designed the outer diameter of stented porcine aortic valve from 19 mm to 33 mm and designed stent height and width, using previous measured ratio of each structure, stent thickness, working thickness (for making valve). Also, we designed the size of stent and form for stented bovine pericardial valve, considering diameter of valve, leaflet length, height and leaflet minimum coaptation area. Conclusion: By measuring of 25 pig's aortic and pulmonary valve geometry and ratio, we can make theoretical basis for making implantable stented porcine valve and bovine pericardial valve in various size. After making implantable valve using these data, it is necessary to do in vivo and in vitro researches, furthermore.

  • Background: The incidence of adenocarcinoma of the lung has been increasing worldwide, and it has been generally been accepted to be relatively unrelated to smoking with a female preponderance. The aim of this study was to examine the gender-related pathological and survival differences in patients with an adenocarcinoma of the lung. Material and Method: A retrospective review of the clinical information of patients diagnosed with an adenocarcinoma of the lung at Kosin Medical Center from January 1999 to September 2005 was performed. The patient's demographics (age, gender), smoking history, stage, serum tumor marker, pathology classification, EGFR mutation, K-ras mutation, treatment methods, and survival time were analyzed. Result: Of the 438 patients, 179 (40.9%) were female. The median age at the diagnosis was 58 years for females and 59 years for males. However, 25.8% of women and only 17.7% of men were under 50 years of age (p=0.02). The distribution of the disease stage was similar in both men and women. The bronchioloalveolar carcinoma component was diagnosed more often in women (11.2%) than in men (5.0%). The overall survival rate was higher in women than in men (p=0.01), and women had a superior therapeutic response to a combined treatment of surgery and chemotherapy. Conclusion: This study showed significant genders differences in terms of the smoking history, bronchioloalveolar carcinoma component, overall survival, and survival after combined treatment of surgery and chemotherapy. Therefore, gender differences should be considered when diagnosing and treating adenocarcinomas of the lung.

  • Objectives : The objective of this study is to measure and to compare the rate of depression, anxiety, self-es-teem and the quality of life of the patients with chest pain. Based on the result of this study, the necessity of the psychiatric assessment and treatment of the patients with chest pain is emphasized. This study is a preliminary research for a larger scale investigation to be carried out in the future. Methods : Thirty nine patients with chest pain who visited Cardiovascular Division of Dept. of Internal Medicine Pusan National University Hospital and fourty normal control group(NC) were included in this study. The patients were classified into typical chest pain group(TCP, N=19) and atypical chest pain group(ACP, N=20) based on the cause of the pain. The cause was determined by cardiac computed tomography, exercise stress test, coronary angiography, and questionaires by a cardiology specialist. The patients were assessed with Beck Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI), Rosenberg Self-Esteem Scale(RSES) and Korean version of the Smith Klein Beecham 'Quality of Life' scale(KvSBQOL). Results : 1) When the risk factors of cardiac disease is compared, most of the factors(Hypertension, Diabetes, Hyperlipidemia, Cerebral infarction) did not differ significantly among the two chest pain groups, except for the family history, for which TCP group showed higher risk than ACP group did. 2) As for the self-report questionaires scores, BDI score, which indicates the rate of depression, of both ACP group and TCP group was significantly higher than that of NC group in BDI for depression. STAI score, which measures anxiety, was also significantly high in both groups. Especially, STAI score was significantly higher in ACP group than TCP group. 3) In the aspect of self-esteem and quality of life, ACP group scored significantly lower than TCP group and NC group. The scores for TCP group and NC group did not differ significantly. Conclusions : The patients with chest pain showed more depression and anxiety than normal control group, regardless of the cause of the pain. However, TCP group did not show significantly larger drop in self-esteem and quality of life than ACP group did. This result implies that early psychiatric assessment and treatment is needed for the patients with such chest pain, since it is highly likely that the pain would lead to lower quality of life of the patients.

  • As a previous study to investigate recognition gap of creativity between Korea and America, this study has examined Korean university students' implicit creativity toward Korea and America. The research method using in this study was as follows: The subject were university students in Korea, and they were asked to answer multiply for open-ended questions. For the analysis of the answers, a frequency analysis was used. The results were as follows: 1) It showed that Korean university students considered creativity trait as cognitive trait, personality, cultural trait, research and development areas and arts areas. This result means that Korean university students tend to recognize creativity similarly to the ways of established theories of creativity. 2) For the case of Korea, environmental trait like sociocultural background had great importance for all cases of creativity trait and non-creativity trait. 3) American creativity was recognized focused on individual tendency, on the while, community spirit was considered as creativity trait in Korean creativity. 4) It is considered that American culture had better condition for displaying creativity than Korean culture. 5) Traditional culture of Korea was recognized as creativity trait in terms of originality and superiority, and the possibility of modernistic use of Korean culture. 6) Creative people were ranked by artists, executives, rulers and scientists who were well-known to Korean university students. 7) In the comparison of creativity trait between the two countries revealed the traits of creative people, American creativity was reflected more than Korean creativity, This result seems that those people were favored by Korean university students who were familiar with American culture. In conclusion, this study has found another possibility of creativity of the East among cross-cultural creativity studies. Moreover, this study has suggested that traditional culture and tradition renewal, and values of the East are superior cultural resources which are not exist in the West, and those are expected to play a role in developing creativity.

  • With accumulated research evidence, there is little doubt that leadership behavior is related to a wide variety of positive individual and organizational outcomes. Indeed, leadership behavior has been empirically linked to increased employee satisfaction, organizational commitment, extra effort, turnover intention, organizational citizenship behavior, and overall employee performance. Although leadership behavior has been linked to a number of positive organizational outcomes, research regarding the antecedents of such behavior is limited. Especially there is little research dealing with the antecedents of inter-organizational leadership behavior. This study interests in inter-organizational ethical leadership among marketing channel members. In both the mass media and the academic association, there has been a surge in interest in the ethical and unethical behavior of leaders. Although the corporate scandals in recent years may explain much of the mass media and popular focus, academics' interest has been limited by evidence that ethical leadership behavior is associated with both positive and negative inter-organizational processes and performances. This study tried to contribute to this body of knowledge by examining antecedents of ethical leadership. Ethical leadership is defined "the demonstration of normatively appropriate conduct through personal actions and interpersonal relationships, and the promotion of such conduct to followers through two-way communication, reinforcement, and decision-making." Ethical leaders not only inform individuals of the behefits of ethical behavior and the cost of inappropriate behavior, such leaders also set clear standards and use rewards and fair and balanced punishment to hold followers accountable for their ethical conduct. Despite the assume importance and prominence of ethical leadership among organizations, there are still many questions relating to its antecedents and consequences. One is whether the likelihood of an leading organization being perceived as an ethical leader among other following organizations in marketing channels can be predicted using its characteristics and inter-organizational relationship maintenance skills. Identifying trait and skill antecedents will aid in the development of strategies for selecting and developing ethical leaders and determining the best means to reinforce ethical behaviors. The purpose of this study is to investigate the effects of three categorized variables on ethical leadership of channel leader. To be concrete, this study develops a model of the antecedents of three conceptually distinct forms of channel leader characteristics, such as organizational traits, inter-organizational relationship maintenance strategies, and supplier management strategies, and tests the hypothesized differential effects on ethical leadership of marketing channel leaders. The reason why this study deals with discount store channel is that there is very strong inter-dependence between a discount store and its suppliers. Their strong inter-dependence makes their relationship as the relationship between a leader and suppliers and creates an atmosphere that leadership occur without difficulty. The research model is as follows. For the purpose of empirical testing, 295 respondents of suppliers of discount store channel in Korea were surveyed. The procedures included scale reliability, and discriminant and convergent validity were used to validate measures. Also, the reliability measurements traditionally employed, such as the Cronbach's alpha, were used. All the reliabilities were greater than .70. This study conducted confirmatory factor analyses to assess the validity of our measurements. All items loaded significantly on their respective constructs(with the lowest t-value being 15.2), providing support for convergent validity. We then examined composite reliability and average variance extracted(AVE). The composite reliability of each construct was greater than .70. The AVE of each construct was greater than .50. This study tested research model using Partial Least Square(PLS). The estimation of the structural equation model revealed an acceptable fit of the model to the data($r^2$=.851). Thus, This study concluded that the model fit was considered acceptable. The results of PLS are as follows. The results indicated that conscientiousness, openness, conflict management, social networks, training, fair reward had positive effects on ethical leadership of channel leaders. On the other hand, emotional insecure had negative effect and agreeableness, assurance, and inter-organizational communication had no significant effect on supply chain leadership.

  • Objectives: Firefighters are known to be exposed to a variety of toxic substances, but little information is available on the exposure profile of firefighting activities. The aims of this study were to conduct exposure monitoring of toxic chemicals at fire scenes, to compare the concentrations of respective chemicals among firefighting tasks, and to assess the main factors influencing the concentrations of chemicals. Methods: Researchers performed sampling at firefighting scenes during four weeks in 2013. At the scene, we collected samples based on firefighters' own activities and examined the situation and scale of the accident. Collected samples were classified into three categories, including fire extinguishing and overhaul, and were analyzed in the laboratory according to respective analysis methods. Results: A total of fourteen fire activity events were surveyed: five fire extinguishing, six overhaul, and three fire investigations. Although no substance exceeded the ACGIH TLV, PAHs were detected in every sample. Naphthalene ranged from 0.24 to 279.13 mg/㎥ (median 49.6 mg/㎥) and benzo(a)pyrene was detected in one overhaul case at 10.85 ㎍/㎥. Benzene (0.01-12.2 ppm) was detected in every task and exceeded the ACGIH TLV. No significant difference in concentrations between tasks was shown. Conclusions: These results indicate that all firefighting tasks generated various hazardous combustion products, including possible carcinogens.
