오늘날 많은 이들이 클라이언트-서버 컴퓨팅은 차세대 전산 환경의 주역이 될 것으로 인신하고 이미 여러 기업에서 정보시스템을 크라이언트-서버 환경으로 구축해 왔다. 하지만, 이러한 많은 관심과 노력에도 불구하고 만족할 만한 결과를 얻지 못하고 있는 실정이다. 이러한 회의적인 방응에 대한 원인으로는 많은 요인들이 있겠지만 연구에서는 무엇보다도 기업의 다양한 정보처리 특성에 대한 면밀한 검토 없이 시대적 조류에 밀려 도입에 급급했다는 것을 지적하고 있다. 그래서, 본 연구에서는 다섯 가지 클라이언트-서버 아카텍춰들,일곱 가지의 정보 처리에 관련된 기준에 따라 평가 분석해 보고 기업의 정보처리 특성과의 적합성을 분석하여 가장 이상적인 클라이언트-서버 아키텍취를 제안한다. 그리고 제안된 아카 텍춰를 기반으로 성공적인 정보 시스템이 구현될 수 있는 전략을 제시한다. 마지막 으로 본 논문에서 제시된 상황모델의 검증을 위해 클라이언트-서버기술을 구현한 세가지 사례를 탐색적 수준에서 분석해 보았다.

This study examined the effects of gender, parental support and treatment type on the treatment outcome of adolescent substance abusers. Outcome variable was the successful graduation (or drop) from an Intensive Adolescent Outpatient Program. Adolescents with their parents' support were treated in one of three treatment models (2-weeks Inpatient plus 6 week Intensive Croup-Oriented Outpatient, 8-weeks Intensive Croup-Oriented Outpatient, and 8-weeks Individual-Family Therapy) within a private hospital-affiliated treatment center by managed care practice allowing their own choice (non-random natural assignments). Several hypotheses were tested for main effects by the Log-Linear Analyses for a multi-dimensional contingency table with 440 adolescents (284 boys and 156 girls treated during 1992-l997) from middle-class families with private health insurances. The following results were found. Odds of graduating versus dropping out of the treatment program among : (1) girls were 1.7 times higher than those among boys; (2) adolescents with two-parent were 2.2 times higher than those among adolescents with one-parent ; (3) adolescents with Inpatient plus Outpatient was 1.7 times higher than that of those with Outpatient; (4) adolescents with Individual-Family Therapy was 2.3 times higher than that of those with Outpatient Model. There was no statistically significant outcome difference between the Individual-Family Therapy and the Inpatient plus Outpatient. Implications from the results were discussed. Suggestions were made to improve the treatment components in the areas of gender sensitivity, securing more parental support, alternatives for separation from peer group and integrating new peer groups, and flexibility for the unique needs of individual family. Also, some research questions for future studies were suggested.

Complete surgical resection of the primary tumour is a crucial predictive step for head and neck squamous cell carcinoma (HNSCC), because incomplete resection may lead to increase in the recurrence rate. Molecular cancer markers have been investigated as potential predictors of prognosis marker, to identify patients who are at high risk of local recurrence. This retrospective study aimed to determine the prognostic correlation between p53 and eIF4E expression and clinical characteristics, recurrence and overall survival. Forty eight HNSCC patients were selected between 2006 and 2009 diagnosed at the Royal Darwin Hospital, Darwin, Northern Territory, Australia. Out of 48, only those 24 with negative surgical margins with hematoxylin and eosin (HandE) were chosedn for further analysis. A total of 77 surgical margins were obtained and subsequently analysed by immunohistochemical (IHC) staining with monoclonal p53 and polyclonal eIF4E antibodies. Contingency table and ${\chi}^2$-test were used to investigate the correlation between p53 and eIF4E expression and clinical characteristics, recurrence and overall survival of the HNSCC patients. The follow up period was 74 months (range 1-74 months). The Kaplan-Meier method was used to generate recurrence and survival curves. This is a first retrospective study of Northern Territory patients, including Indigenous and non-Indigenous Australians. Molecular study of surgical margins could help to identify patients with and without clear margins after surgery and help in choice of the most appropriate adjuvant treatment for HNSCC patients.

The present study attempted to compare the behavioral patterns and attitudes of American and Korean female students toward apparel ads in magazines in relation to their physical self-concept. The study used a self-administered questionnaire. The sample consisted of 730 female students majoring in the fields related to clothing and textiles : 310 American students at six colleges and universities located in the west, northeast and southwest parts of the U.S., and 412 Korean students at four Seoul-based universities. Likert scales were used for most measures with 1=never or very unimportant and 5 =always or very important. Physical self-concept was measured on the basis of W. S. Jung's Standardized Self-concept Test and Tennessee Self-concept Scale. Surreys were back translated for validity. Percentage, t-test, Contingency Tables and Chi-square were used for the analysis of the data. Results are as follows : (1) Korean students read more magazines than U.S. students, however, Vogue was the most popular for both groups. (2) Those with a high sense of Physical self-concept read more magazines. for both countries. (3) American students'attitudes toward apparel ads in magazines were similar, regardless of whether their sense of physical self-concept was high or low. For Koreans, those with higher sense of physical self-concept showed greater interest in magazine ads, consulted magazines for fashion trends, found ads more useful, and more often expressed satisfaction with the ads, than the lower self-concept group. (4) Korean students cited a lack of information in ads while American students felt body types of models were unrealistic. Both Koreans and Americans in the higher self-concept group expressed a greater level of dissatisfaction with apparel ads in magazines. (5) Advertisers should attempt to again a deeper understanding of the socio-psychological characteristics of their readership as self-concept appears to be related to several magazine readership attitudes and behaviors. Magazines targeting Americans might consider the importance of coordination and merchandising. Apparel ads targeting Korean should consider the importance of company ads.

Background: Stage at diagnosis is one of the most important prognostic factors of breast cancer survival. Because in the breast cancer case this may vary with socioeconomic characteristics, this study was performed to recognize the relationship between demographic and socioeconomic factors with stage at diagnosis in Iran. Materials and Methods: This cross-sectional, descriptive study conducted on 526 patients suffering from breast cancer and registered in Cancer Research Center of Shahid Beheshti University of Medical Sciences from 2008 to 2013. A reliable and valid questionnaire about family levels of socioeconomic status filled in by interviewing the patients via phone. For analyzing the data, Multinomial logistic regression, Kendal tau-b correlation coefficient and Contingency Coefficient tests were executed by SPSS22. Economic status, educational attainment of patient and household head and/or a combination of these were considered as parameters for socioeconomic status. First, the relationship between stage at diagnosis and demographic and socioeconomic status was assessed in univariate analysis then these relationships assessed in two different models of multinomial logistic regression. Results: The mean age of the patients was 48.3 (SD=11.4). According to the results of this study, there were significant relationships between stage at diagnosis of breast cancer with patient education (p=0.011), living place (p=0.044) and combined socioeconomic status (p=0.024). These relationships persisted in multiple multinomial logistic regressions. Other variables, however, had no significant correlation. Conclusions: Patient education, combined socioeconomic status and living place are important variables in stage at diagnosis of breast cancer in Iranian women. Interventions have to be applied with the aim of raising women's accessibility to diagnostic and medical facilities and also awareness in order to reducing delay in referring. In addition, covering breast cancer screening services by insurance is recommended.

Network anomaly detection system plays an essential role in detecting network anomaly and ensuring network security. Anomaly detection system based machine learning has become an increasingly popular solution. However, due to the unbalance and high-dimension characteristics of network traffic, the existing methods unable to achieve the excellent performance of high accuracy and low false alarm rate. To address this problem, a new network anomaly detection method based on data balancing and recursive feature addition is proposed. Firstly, data balancing algorithm based on improved KNN outlier detection is designed to select part respective data on each category. Combination optimization about parameters of improved KNN outlier detection is implemented by genetic algorithm. Next, recursive feature addition algorithm based on correlation analysis is proposed to select effective features, in which a cross contingency test is utilized to analyze correlation and obtain a features subset with a strong correlation. Then, random forests model is as the classification model to detection anomaly. Finally, the proposed algorithm is evaluated on benchmark datasets KDD Cup 1999 and UNSW_NB15. The result illustrates the proposed strategies enhance accuracy and recall, and decrease the false alarm rate. Compared with other algorithms, this algorithm still achieves significant effects, especially recall in the small category.

전세계뿐만 아니라 대한민국 정부에서도 저탄소 녹색성장을 실현하기 위해 노력하고 있으며, 그 방안의 하나로 자전거 수송분담율을 높이기 위하여 자전거도로와 자전거 편의시설 등을 확충하고 있다. 이러한 이유로 자전거 이용자들이 많이 증가하고 있는데 반면에 자전거 교통사고도 급증하는 추세이다. 자전거 교통사고 자료는 경찰청에서 발간하는 연감자료가 유일하나, 이 자료는 사고의 빈도수를 이차원 분할표 형태로 제공하고 있기때문에 일반인들이 이 자료를 통하여 사고의 성격과 위험율에 대하여 파악하고 이해하기 어렵다. 따라서 본 연구에서는 자전거사고 자료를 확률로 표현하고 자전거 인구와 자동차 등록대수 자료와 결합하여 자전거사고의 특징을 분석하고 파악한다. 또한 조건부 독립이라는 가정 하에 현실세계의 현상에서 자전거사고 발생확률을 구하는 방법을 제안하고, 이 방법을 활용하여 자전거사고를 줄일 수 있는 방안에 대해 논의한다.
