Purpose - With the worldwide aging problem and the development of globalization, customers prefer to seek affordable medical services with the higher quality overseas. This new trend has urged some destination countries to improve their services for the more competitive advantages over other countries. Literature research indicate that medical quality and cost may be the key factors influencing global patients' decisions. In the international environment, however, medical tourism destinations are selected due to cultural similarity between the hosting country and the customers' own country. The more similarity perceived between the two countries leads foreign patients to choose the considering country as the destination for medical tourism. However, little research has been conducted on this topic. Thus, we empirically investigate how cultural similarity influences Chinese medical customers' choice of the destinations. We also consider the factors related to medical competency and travel attribute which might affect customers' decisions along with some moderating roles of disease types. Research design, data, and methodology - We proposed a research model in order to confirm the relations among different variables of cultural similarity, medical competency, travel attractiveness, disease types, and destination choice. The questionnaire survey is processed in the more economically developed regions of China such as Beijing, Shanghai, and Jiangsu. Conditional logit regression is applied to analyze the data of 881. Results - Results indicate that cultural similarity is the important predictor of Chinese customers' decision to select a medical country. However, the effects of cultural similarity vary according to the disease types. We also find that medical competency and travel attractiveness influence their decisions with the moderating role of disease types. Conclusions - Cultural similarity is the important factor that influences Chinese potential medical tourists' decisions to select a destination. Marketing managers should consider the effects of cultural similarity when developing strategies for attracting Chinese medical tourists. Since medical competency and travel attractiveness are still the critical key elements for them to evaluate the destination countries, it is necessary to continuously improve medical service quality and facilities. The results also recommend that medical managers should sharpen their marketing strategies by segmenting Chinese potential customers in terms of disease types.

Background: To explore etiology for providing scientific clues for the prevention of lung cancer. Materials and Methods: Data for lung cancer incidence and meteorological geographic factors from 25 counties in Zhejiang province of China during 2011 were studied. Stepwise multiple regression and correlation analysis were performed to analyze the geographic distribution and epidemiology of lung cancer. Results: 8,291 new cases (5,998 in males and 2,293 females) of lung cancer during 2011 in Zhejiang province were reported in the 25 studied counties. Reported and standardized incidence rates for lung cancer were 58.0 and 47.0 per 100,000 population, respectively. The incidence of lung cancer increased with age. Geographic distribution analysis shows that the standardized incidence rates of lung cancer in northeastern Zhejiang province were higher than in the southwestern part, such as in Nanhu, Fuyang, Wuxing and Yuyao counties, where the rates were more than 50 per 100,000 population. In the southwestern Zhejiang province, for instance, in Yueqing, Xianju and Jiande counties, the standardized incidence rates of lung cancer were lower than 37 per 100,000 population. Spearman correlation tests showed that forest coverage rate, air quality index (AQI), and annual precipitation level are associated with the incidence of lung cancer. Conclusions: Lung cancer in Zhejiang province shows obvious regional differences. High incidence appears associated with low forest coverage rate, poor air quality and low annual precipitation. Therefore, increasing the forest coverage rate and controlling air pollution may play an important role in lung cancer prevention.

Periodontal disease research has been focused on understanding the immunopathologic mechanisms which may operate in the development and maintenance of peiodontal inflammatory changes. Immunologic and inflammatory responses may relate to the etiology and pathogenesis of periodontal disease. In order to research immunopathology of periodontal disease, previous investigators have spent much time on the distribution of lymphocyte subpopulations and NK cells but they have spent less time on the changes of those cells to the periodontal disease severity. The purpose of study was performed to investigate the changes of the distribution of T lymphocytes, B lymphocytes, T lymphocyte subsets, and Natural Killer cells in the gingival epithelium and connective tissue of the periodontal disease with the various clinical parameters including Gingival Index, Sulcular Bleeding Index, and pocket depth. Gingival tissues were obtained from 25 patients with different severity of periodontal disease. Serial cryostat sections displaying a cross section of gingiva were labelled with monoclonal antibody for pan T cells, T cytotoxic/suppressor cells, T helper/inducer cells, pan B cells, and NK cells were develped using an avidin-biotin-peroxidase system. Lymphocyte populations were enumerated in repeatable fields from gingival section. 1. T cells were more increased at grade 1 and 3 than at grade 0 of gingival index (p<0.05). Helper T cells and NK cells were significantly increased at grade 1, 2, 3 than at grade 0(p<0.05). 2. T cells were more decreased at grade 3 and 4 than at grade 1 of sulcular bleeding index (p<0.01, p<0.05). Especially, Natural Killer cells were significantly increased at grade 1, 2, 3, 4 than at grade 0 (p<0.05, p<0.001). 3. The ratios of helper T/suppressor T cells were more decreased at grade 4 than at grade 0 and at grade 4 than at grade 2 of sulcular bleeding index (p<0.05, p<0.05). 4. Helper T cells were significantly decreased at grade II and III than at grade I, however the Natural Killer cells showed a increasing tendency with the increase of the pocket depth, there were no significant differences between each grade of pocket depth. 5. The ratios of helper T/suppressor T cells were tended to be decreased with the increase of the pocket depth, there were no significant differences between each grades of pocket depth. There was a very weak change in the distribution of T lymphocytes, B lymphocytes, T lymphocyte subsets, and Natural Killer cells in the gingival epithelium and connective tissue of the periodontal lesion with the various clinical parameters including gingial index, sulcular bleeding index, and pocket depth. But, the number of T lymphocytes and Natural Killer cells were significantly changed in gingival index and sulcular bleeding index.

Methods: We investigated 391 outpatients who visited Dong-Eui Oriental Hospital OB & GY from June 12, 2013 to April 18, 2014. Among 134 patients who complained feeling of cold, we analyzed 107 patients whose Sasang constitution is confirmed. Results: 1. There were 21 persons 19.8% of under age 27, 28 persons 26.4% of age 28-34, 23 persons 21.7% of age 35-41, 18 persons 17% of age 42-48, 16 persons 15.1% of age over 49. 2. Among 107 patients, there were 52 persons 48.6% of Soeumin, 29 persons 27.1% of Taeeumin, 25 persons 23.4% of Soyangin, 1 person 0.9% of Taeyangin. And Taeyangin interior disease was 1 case 100%, Soyangin exterior disease was 22 cases 88% and interior disease was 3 cases 12%, Taeeumin exterior disease was 11 cases 37.9% and interior disease was 18 cases 62.1%, Soeumin exterior disease was 19 cases 36.5% and interior disease was 33 cases 3.5%. 3. In the distribution of cold-hypersensitive part, hands and feet with chills were 58 cases 4.7% by largest number, and the following was hands and feet in 24 cases 22.6%. 4. In the distribution of chief complaint, there were 25 cases 23.58% of menstrual pain, 19 cases 17.92% of postpartum symptoms, 17 cases 16.04% of oligomenorrhea and hypomenorrhea, 14 cases 13.21% of cold hypersensitivity. 5. In the distribution of chief complaint depending on age, menstrual pain of under age 27, postpartum symptoms of age 35-41 and cold hypersensitivity of over age 49 were at a high rate. Conclusions: Results suggest that patients with symptom of cold hypersensitivity have some tendencies in age, Sasang constitution, chief complaint, cold-hypertensive part.

It has been approximately 40 years since $Br{{\aa}}nemark$ first introduced osseo-integration for implants in the early 1960s. Unlike crown and bridge or denture treatment, implant treatment helps preserve existing bone and improve masticatory functions. Thus, the awareness of implant treatment has grown rapidly among dentists and patients alike in Korea, as it becomes a widely accepted treatment. The following results on patients type and implant distribution were compiled from 1814 implant cases of 640 patients treated at the periodontal dept. of Y University Hospital during 1992 to 2001. 1. There are no dissimilarities between men and women, with patients in their 40,50s accounting for 49% of patients and 56% of implant treatments; the largest share of patients and implant treatments. 2. Mn. posterior area accounted for 59% of implant treatments followed by Mx. posterior area(21%), Mx anterior area(l4%) and Mn anterior area 2%. 3. Partial edentulous patients treated by single crown and bridge-type prosthesis accounted for 98% and fully edentulous patient accounted for the remaining 2% 4. The major cause of tooth loss is periodontal disease, followed by dental caries, trauma and congenital missing. Compared to women, men are more likely to suffer from tooth loss due to periodontal disease. Also, older people are more likely to suffer from tooth loss due to periodontal disease rather than dental caries. 5. The distribution of bone quality for maxillae was 52% for type III, followed by 23% for type II, 20% for type IV and 0% for type I. As for mandible, the distribution was 52% for type II, followed by 37% for type III, 7% for type IV and 4% for type I. 6. The distribution of bone quantity for maxillae was 49% for type C, followed by 34% for type B, 14% for type D, 3% for type A, and 0% for type E. As for mandible, the distribution was 52% for type B, followed by 35% for type C, 6% for type D, 3% for type A and 0% for type E. 7. The majority of implants were those of 10-14mm in length (80%) and regular diameter in width (79%). The results provided us with basic data on patient type, implant distribution, bone condition, etc. We wish that our results coupled with other research data helps assist in the further study for better implant success/survival rates, etc.
