  • Osteoarthritis(degenerative joint disease), the most common arthropathy affecting the aged people, is characterized by degeneration of articular cartilage with proliferation and remodeling of subchondral bone. Osteoarthritis of the knee, which probably has greater social cost and more associated disability than osteoarthritis of any other joint, prevalence is known to increase with age, and females have higher rates than males; radiographic abnormalities are present in more than 30% of persons more than 65 years old, with approximately 40% of these persons symptomatic. Though the etiology of osteoarthritis is not entirely understood, much information is available regarding risk factors for the development of knee osteoarthritis that permit some reasonable guideline for preventive strategies. Traumatic damage or occupational or recreational overuse of knee joint may result in osteoarthritis, and obesity also is related to osteoarthritis of the knee. A variety of other possible risk factors for the development of knee osteoarthritis have been proposed, including increased bone mass, smoking, diseases such as diabetes or elevated serum uric acid, and some metabolic factors, but the contribustions of these and other factors such as smoking or race and diseases such as diabetes are as yet undetermined. The usual clinical manifestations include pain, stiffnesss, crepitus and loss of function. In oriental medicine, osteoarthritis of the knee is very similar to diseases such as Bijung(痺症), Haksulpung(鶴膝風), Youkjeolpung(歷節風) in symptoms. The diseases such as Bijung(痺症), Haksuipung(鶴膝風), Youkjeolpung(歷節風) is related to the of function liver(肝) and kidney(腎) and risk factors are regarded as Pung(風), Han(寒), sub(濕). The diagnosis of osteoarthritis of the knee has often been based on radiographic appearance and clinical manifestations. The acupuncture therapy of osteoarthritis of the knee has often been based on Stomach meridian(ST), Spleen meridian(SP), Kidney meridian(KI), Liver meridian(LR).

  • Objectives: In the USA, certain races and ethnicities have a disproportionately higher gastric cancer burden. Selective screening might allow for earlier detection and curative resection. Among a USA-based multiracial and ethnic cohort diagnosed with non-cardia gastric cancer (NCGC), we aimed to identify factors associated with curable stage disease at diagnosis. Methods: We retrospectively identified endoscopically diagnosed and histologically confirmed cases of NCGC at Mount Sinai Hospital in New York City. Demographic, clinical, endoscopic and histologic factors, as well as grade/stage of NCGC at diagnosis were documented. The primary outcome was the frequency of curable-stage NCGC (stage 0-1a) at diagnosis in patients with versus without an endoscopy negative for malignancy prior to their index exam diagnosing NCGC. Additional factors associated with curable-stage disease at diagnosis were determined. Results: A total of 103 racially and ethnically diverse patients were included. Nearly 38% of NCGC were stage 0-Ia, 34% stage Ib-III, and 20.3% stage IV at diagnosis. A significantly higher frequency of NCGC was diagnosed in curable stages among patients who had undergone an endoscopy that was negative for malignancy prior to their index endoscopy that diagnosed NCGC, compared to patients without a negative endoscopy prior to their index exam (69.6% vs. 28.6%, p=0.003). A prior negative endoscopy was associated with 94.0% higher likelihood of diagnosing curable-stage NCGC (p=0.003). No other factors analyzed were associated with curablestage NCGC at diagnosis. Conclusions: Endoscopic screening and surveillance in select high-risk populations might increase diagnoses of curable-stage NCGC. These findings warrant confirmation in larger, prospective studies.

  • Orthodontists want why the patients want orthodontic treatment. Demand and need for orthodontics is very important factors of cooperation and management. Chief complaint would be different according to the race and culture. Our results show that in the control group, Korean female adolescents[chief complaint is cowding$(30.6\%)$, spacing$(26.5\%)$, upper anterior protrusion$(18.4\%)$, anterior cross bite$(8.2\%)$ in order. Korean female adolescents considered anterior cross bite is more nonacceptable than spaeing and anterior protrusion. The purpose of orthodontics seemed to enhance esthetic, dental health, and to improve oral function.

  • There is growing scientific evidence linking excess body weight to breast cancer risk. However, there is no common consensus on this relation due partly to methodologies used, populations studied and the cancer subtype. We report here a summary of the present state of knowledge on the role of overweight and obesity in pathogenesis of breast cancer and possible mechanisms through which excess body weight might influence the risk, focusing on the role of oxidative stress in breast cancer etiology. The findings demonstrate duality of excess body weight action in dependence on menopausal status: a statistically significant increased risk in postmenopausal overweight/ obese women and non-significant preventive effect among premenopausal women. Due to several gaps in the literature on this topic, additional studies are needed. Future research should address factors influencing the excess body weight - breast cancer relationship, such as race/ethnicity, tumor subtype, receptor status, the most appropriate measure of adiposity, reproductive characteristics, and lifestyle components.

  • This paper aims to reach the perceptions, ideas and intentions of the higher education adolescences on the effects of technological innovations over interrelation/communication between individuals. While advances in technology commonly works for the welfare and benefit of humankind, paradoxically in some instances could have negative outcomes on interrelations among individuals, minimizing face-to-face communication. The perceptions, so ideas of the individuals on the matter could differ depending on their age, gender, race and the culture beyond their relative intimacy and closeness to ICT tools. In order to penetrate the basic initiatives leading the perceptions of adolescents on the effects of technological improvements on human interrelations/ communication, a survey is conducted with 157 students in high education consisting of Asian, African, Cypriot, Turkish nationals. Results indicate that participants use technological tools for communication which lessens their face-to-face interaction. However they prefer social media more than face-to-face communication during conflict or undesirable situations.

  • Idiopathic Parkinson's disease (IPD) represents a common neurodegenerative disorder. While epidemiological studies have suggested a number of risk factors including age, gender, race, and inherited disorder, the cumulative evidence supports the view that environmental or occupational exposure to certain chemicals may contribute to the initiation and progress of Parkinsonism. More recently, clinical and laboratory investigations have led to the theory that dysregulation of iron, an essential metal to body function, may underlie IPD by initiating free radical reaction, diminishing the mitochondrial energy production, and provoking the oxidative cytotoxicity. The participation of iron in neuronal cell death is especially intriguing in that iron acquisition and regulation in brain are highly conservative and thus vulnerable to interference from other metals that bear the similar chemical reactivity. Manganese neurotoxicity, induced possibly by altering iron homeostasis, is such an example. In fact, the current interest in manganese neurotoxicology stems from two primary concerns: its clinical symptoms that resemble Parkinson's disease and its increased use as an antiknock agent to replace lead in gasoline. This article will commence with addressing the current understanding of iron-associated neurodegenerative damage. The major focus will then be devoted to the mechanism whereby manganese alters iron homeostasis in brain.

  • Using data from the 2001 American Housing Survey, the purpose of this study is to profile the economic and socio-demographic characteristics of baby boomers according to housing down payment sources and to identify determinants of housing down payment sources among baby boomers. Results of the multinomial logistic regression analysis indicated that household income, housing value, age, education, gender, marital status, race, and geographic region were all significant determinants of housing down payment sources among baby boomers. Identification of factors affecting the occurrence of borrowing for housing down payment would aid in the development of financial education programs for baby boomer households.

  • We investigate the latent stage-sequential patterns of drinking behaviors of U.S. adolescents who have started to drink by age 14 years (seven years before the legal drinking age). A multiple-group latent transition analysis(LTA) with logistic regression is employed to identify the subsequent patterns of drinking behaviors among early-onset drinkers. A sample of 1407 early-onset adolescents from the National Longitudinal Survey of Youth(NLSY97) is analyzed using maximum-likelihood estimation. The analysis demonstrates that early-onset adolescents' drinking behaviors can be represented by four latent classes and their prevalence and transition are influenced by demographic factors of gender, age, and race.

  • Insurance companies are in a fierce race to catch a new customer. In this situation. sales force automation technologies are often used to support customer relationship management strategies. This study sets out a research model predicting SFA(Sales Force Automation) usage through theoretical studies. Survey data were collected from 145 salespeople across 2 firms that had implemented sales force automation tools and hypotheses were tested empirically. Data were analyzed by path-analysis method of AMOS. The major findings of this study are as follows: Computer self-efficacy, user involvement and voluntariness have a statistically significant influence on the positive perceptions of SFA. These perceptions have a statistically significant influence on user satisfaction and usage of SFA. while user satisfaction has a statistically significant influence on SFA usage. This paper concludes with the discussion of these results and their implications for academic researchers and insurance company managers.
