Purpose: Free cancer cells exfoliated from cancer-invaded serosa contribute to peritoneal dissemination, the most frequent pattern of recurrence in patients with gastric cancer. To detect free cancer cells, CEA and CA19-9 were introduced as the markers of gastric cancer, and many methods, such as cytology, immunoassay, and reverse transcription polymerase chain reaction (RT-PCR), exist for detecting them. The aim of this study is to define the clinical significance of using immunoassay to measure the levels of CEA and CA19-9 in the peritoneal washings in patients with gastric cancer. Materials and Methods: The peritoneal washing fluids were obtained from 130 patients with gastric cancer who received a curative gastrectomy, palliative gastrectomy or open and closure. The pCEA and pCA19-9 levels were measured by using immunoassay and cytology. The results were compared with the clinicopathological data. Results: The pCEA and pCA19-9 levels were correlated with tumor invasion, lymph-node metastasis, and stage (P<0.05). Conclusion: A correlation was found between elevated pCEA and pCA19-9 levels measured by immunoassay and the TNM stage. Therefore, a combined pCEA and pCA19-9 assay could be a sensitive detector of peritoneal dissemination, as well as a predictor of postoperative prognosis. pCEA and pCA19-9 may also determine the adjuvant management strategy.

Korean private colleges under the period of Japanese control was the kernel for the educational resistance, one of the save-the-nation movements because of inculcating in Koreans the spirit of independence and self-respect under that period. Posung College Library building, erected in Commemoration of the 30th Anniversary of the Foundation, especially, was the result of Koreans systematizing ability and iron will of independence for the future generations. In this paper, an attempt to study the Korean private college libraries under the period of Japanese control is provided. The main institutions in this study are Posung College library, Chosen Christian College library (Yunhee College Library), and Ewha College Library. This study will focus to review the followings: 1. The historical background of above mentioned libraries. 2. The educational resistance under that period. 3. The comparative and analytical study of these private college libraries and Keijo Imperial University library. 4. The facilities and the basic collection development plan on the basis of presentation. 5. library services including readers services. 6. The impact of these libraries on the present private university libraries. 7. The organization and staffing pattern, and budget of these private college libraries. The followings are the outlines conclusions: 1. Korean private college libraries had been established in order to perform the educational resistance. They are one of the supporting agencies for the research activities, among the most important means of social education, and provide, no doubt, the full nutriment for hungry soul under that period. 2. These libraries have not outstripped Keijo Imperial University in collection of books as well as man power, but their collection of books coincided, in general, with their curricula, and had feature to perform the save-the-nation-movement by education. 3. The library services were appeared in the forms such as the Circulation Library, Lectures on the Use of Books and Libraries, Library Week, and Training Course for the Librarians, etc. It is thought that these activities contributed to the social and cultural development of Korea indirectly. 4. The library administration of the private colleges depended upon the director of library because of the frequent changes of staffs and the simple functional system without its middle class. 5. The Japanese Government-General in Korea gave no financial assistance to the private colleges though they were in financial difficulties more than Keijo Imperial University. 6. The ambitious ideal for foundation of universities in reality as well as in name was not achieved during that period because of the monstrous obstacle so-called the Japanese Government-General in Korea, but its ideal had a desirable effect upon these college libraries development, in particular, before and after 1935.

Objectives: We aimed to evaluate the use of Korean medicine in patients with dizziness or vertigo, since such study has not been performed previously. Methods: In the current study, we included 3 diagnoses i.e., Disorders of vestibular function (H81), Vertiginous syndromes in diseases classified elsewhere (H82), and Dizziness and giddiness (R42) from the Health Insurance Review and Assessment Service (HIRAS) database for 4 years. We analyzed the database and compared treatment with Korean vs. Western medicine. Results: 1. Korean medical visits and cost have been increasing for 4 years, except 2011. Western medical visits are 11.9 times higher than Korean medical visits. 2. The number of women who received Korean medicine was 2.6 times higher than that of men. 3. Among all ages, the 70~79 years group were the most frequent users of Korean medicine. The older age was correlated with more patients' visits. 4. The comparative number of visits by patient care type for 4 years indicated that outpatients had more visits than hospitalization. Furthermore, outpatient visits have been increasing for 4 years. 5. The comparative number of visits by hospital type for 4 years indicated that visits to the Korean medical clinic were the highest. In primary care, patients used more Korean medicine than Western medicine. In tertiary care, patients used more Western medicine than Korean medicine. 6. Korean medical cost per patient by patient care type for 4 years was a total 89,000 won, hospitalization 449,000 won and outpatient 83,000 won. Costs of all patient care types have been increasing. 7. Korean medical cost per patient by hospital type for 4 years was 156,000 won for Korean medical hospital, 83,000 won for local clinic and 127,000 won for miscellaneous facilities. Costs of all types have been increasing. Conclusions: This study provided objective information about epidemiologic characteristics of Korean medicine in patients with dizziness or vertigo. Furthermore, it provides an understanding of the recent status and forms the basis for further expansion of demand for Korean medicine among patients with dizziness or vertigo.

Purpose : Group A streptococci(GAS) was isolated from the patients with acute pharyngitis. Epidemiological studies using T typing and emm genotyping was performed for GAS and compared with the results of the carriers. Methods : Throat cultures were taken from 246 children(123 boys, 123 girls) from November, 2001 to May, 2002 who visited a pediatrician's office located in Jinju, Gyeongnam province. T types were identified with slide agglutination and emm genotypes were identified with DNA sequencing after amplification of emm genes. Results : One hundred thirty(52.8%) out of 246 children yielded beta-hemolytic streptococci, of which 96.1% were group A. Children from 4 to 7 years old comprised 70.4% of the GAS positive group. T12 were the most common(35.2%) and T non-typeable strains were the next(30.4%). emm12 was most frequent(28.5%), and emm75(18.7%), emm22(13.0%), emm2(12.2%), and emm8(8.1%) were relatively common. Conclusion : Since GAS is so highly prevalent in acute pharyngitis, indeed being half of the population, good clinical practice dictates the systematic employment of throat culture for acute pharyngitis before prescribing antibiotics in a pediatric setting. The distribution of the T antigens and emm genes showed similar pattern between the acute pharyngitis and the carriers.
Apartments are built in small countries to accommodate densely populated cities and maximize urbanization. Many apartment complexes have been built in recent reconstruction or redevelopment projects. An increase in crime has resulted due to residents living in a narrow space. Larceny is the most commonly reported crime in apartment complexes. Apartments can be classified as stairway, hallway, or plane surface. This study compares and analyzes the frequency of theft by apartment type to assist in creating a safer residential space. In America and England, scholars studied to make a safer residential space, and have applied the theory of 'the Defensible Space' and 'Crime Prevention Through Environmental Design(CPTED)' since 1970s. Korean apartment design now reflects CPTED in new apartment construction. In this study, 12 apartment complexes were selected in Changwon city to conduct analysis of theft in selected complexes. The study will cover housing invasion theft, motorcycle and car theft and snatching. The most frequency larceny is motorcycle and car theft, the second is housing invasion theft, and the least frequent is snatching. More residents' motorcycles and cars are damaged in a hallway style apartment. More frequently inhabitants have their possessions snatched on a stairway form. 1) When we build new apartment complexes, we must plan to improve territoriality and enhance a natural surveillance by reinforcing dwellers' relationship. Through planning we can prevention the larceny in apartments.
Background: Aberrant promoter hypermethylation has been recognized in human breast carcinogenesis as a frequent molecular alteration associated with the loss of expression of a number of key regulatory genes and may serve as a biomarker. The E-cadherin gene (CDH1), mapping at chromosome 16q22, is an intercellular adhesion molecule in epithelial cells, which plays an important role in establishing and maintaining intercellular connections. The aim of our study was to assess the methylation pattern of CDH1 and to correlate it with the expression of E-cadherin, clinicopathological parameters and hormone receptor status in breast cancer patients of Kashmir. Materials and Methods: Methylation specific PCR (MSP) was used to determine the methylation status of CDH1 in 128 invasive ductal carcinomas (IDCs) paired with the corresponding normal tissue samples. Immunohistochemistry was used to study the expression of E-cadherin, ER and PR. Results: CDH1 hypermethylation was detected in 57.8% of cases and 14.8% of normal adjacent controls. Reduced levels of E-cadherin protein were observed in 71.9% of our samples. Loss of E-cadherin expression was significantly associated with the CDH1 promoter region methylation (p<0.05, OR=3.48, CI: 1.55-7.79). Hypermethylation of CDH1 was significantly associated with age at diagnosis (p=0.030), tumor size (p=0.008), tumor grade (p=0.024) and rate of node positivity or metastasis (p=0.043). Conclusions: Our preliminary findings suggest that abnormal CDH1 methylation occurs in high frequencies in infiltrating breast cancers associated with a decrease in E-cadherin expression. We found significant differences in tumor-related CDH1 gene methylation patterns relevant to tumor grade, tumor size, nodal involvement and age at diagnosis of breast tumors, which could be extended in future to provide diagnostic and prognostic information.
Purpose: This study was performed to evaluate the position of impacted mandibular third molars in different skeletal facial types among a group of Iranian patients. Materials and Methods: A total of 400 mandibular third molars in 200 subjects with different types of facial growth were radiographically investigated for their positions according to their types of facial growth on the basis of the ${\beta}$ angle. The subjects were divided into three groups (class I, II, and III) according to ANB angle, representing the anteroposterior relationship of the maxilla to the mandible. Meanwhile, the subjects were also divided into three groups (long, normal, and short face) according to the angle between the stella-nasion and mandibular plane (SNGoGn angle). ANOVA was used for statistical analysis. Results: The mean ${\beta}$ angle showed no significant difference among class I, II, and III malocclusions (df=2, F=0.669, p=0.513). The same results were also found in short, normal, and long faces (df=1.842, F=2, p=0.160). The mesioangular position was the most frequent one in almost all of the facial growth patterns. Distoangular and horizontal positions of impaction were not found in the subjects with class III and normal faces. In the long facial growth pattern, the frequency of vertical and distoangular positions were not different. Conclusion: In almost all of the skeletal facial types, the mesioangular impaction of the mandibular third molar was the most prevalent position, followed by the horizontal position. In addition, ${\beta}$ angle showed no significant difference in different types of facial growth.

Statement of problem. According to the fracture pattern in several reports, fractures most frequently occur in the interface between the ceromer and the substructure. Purpose. The aim of this in vitro study was to compare the macro shear bond strength and microshear bond strength of a ceromer bonded to a fiber reinforced composite (FRC) as well as metal alloys. Material and methods. Ten of the following substructures, type II gold alloy, Co-Cr alloy, Ni-Cr alloy, and FRC (Vectris) substructures with a 12 mm in diameter, were imbedded in acrylic resin and ground with 400, and 1, 000-grit sandpaper. The metal primer and wetting agent were applied to the sandblasted bonding area of the metal specimens and the FRC specimens, respectively. The ceromer was placed onto a 6 mm diameter and 3 mm height mold in the macro-shear test and 1 mm diameter and 2 mm height mold in the micro-shear test, and then polymerized. The macro- and micro-shear bond strength were measured using a universal testing machine and a micro-shear tester, respectively. The macro- and micro-shear strength were analyzed with ANOVA and a post-hoc Scheffe adjustment ($\alpha$ = .05). The fracture surfaces of the crowns were then examined by scanning electron microscopy to determine the mode of failure. Chi-square test was used to identify the differences in the failure mode. Results. The macro-shear strength and the micro-shear strength differed significantly with the types of substructure (P<.001). Although the ceromer/FRC group showed the highest macroand micro-shear strength, the micro-shear strength was not significantly different from that of the base metal alloy groups. The base metal alloy substructure groups showed the lowest mean macro-shear strength. However, the gold alloy substructure group exhibited the least micro-shear strength. The micro-shear strength was higher than the macro-shear strength excluding the gold alloy substructure group. Adhesive failure was most frequent type of fracture in the ceromer specimens bonded to the gold alloys. Cohesive failure at the ceromer layer was more common in the base metals and FRC substructures. Conclusion. The Vectris substructure had higher shear strength than the other substructures. Although the shear strength of the ceromer bonded to the base metals was lower than that of the gold alloy, the micro-shear strength of the base metals were superior to that of the gold alloy.
Purpose: In the professional soccer team, we performed pre-seasonal physical examination and analyzed the results to establish a standardization data in relation to their position. Materials and Methods: We performed physical examination to the professional soccer team, consisted 34 player's average age 24.9 years. The examination performed were questionnaire on history, musculoskeletal examination, muscle power test, physiologic test, functional test. Results: According to the relationship between player position and injury pattern,. Knee injuries are most frequent on history. Physical examination outcome was that forward were prone to flexor hallucis longus tendinitis, midfielder for chronic ankle instability, defender for achilles tendinitis. Isokinetic test was done at dominant side, Peak torque to body weight ratio was 55.1%. Physiologic test checked body fat percentage was midfielder was superior as 19.8 (SD 2.9). Functional test out-come was that back strength 125 N. sergeant jump 59.6 cm, reaction time 208.5 sec, flexibility 19.2 m/s, side step 39.9 cm. Conclusion: Pre-seasonal physical examination gave us the standardization data and preventive measurement could be advocated from this results.
This study was attempted to observe leisure time physical activity pattern and its relationship to coronary risk factors (BMI, systolic blood pressure, diastolic blood pressure, serum total cholesterol, triglycerides, fasting blood sugar). Subjects participated in this study were 277 adult male workers of an industry in Kyungpook province, Korea. Energy expenditure were measured using modified Physical Activity History questionnaire of CARDIA study by interviewing. Serum total cholesterol, triglycerides and blood sugar level were tested with 5 ml fasting blood and height, weight and blood pressure were masured. Data on smoking and drinking habits and others were obtained. Geometric mean of leisure time physical energy expenditure were estimated as 212.80 kcal per week for study subjects and only 22.4% of them expended 2,000 kcal or more per week in leisure time physical activity. Taking walks or hikes and jogging or running were more frequent leisure time physical activities in study subjects. Statistically significant mean differences in total weekly leisure time physical activity for all coronary risk factors were not found among three groups. Because energy expenditure of leisure time was generally low in this subjects and most of them were healthy men, we did not found that leisure time physical activity was significantly associated with coronary risk factors.
