서문석,James Langabeer 대한예방의학회 2018 Journal of Preventive Medicine and Public Health Vol.51 No.4

Objectives: To identify factors responsible for potentially clinically unnecessary cervical cancer screenings in women with prior hysterectomy. Methods: A retrospective cross-sectional study was conducted using the Centers for Disease Control and Prevention’s Behavioral Risk Factor Surveillance System (BRFSS). This study targeted adult women and examined whether they received a both a Papanicolaou (Pap) test and undergone a hysterectomy in the last three years. We conducted multivariate analyses, including weighted proportions and odds ratios (ORs), based on the modified BRFSS weighting method (raking). The inclusion criteria were adult women (>18 years old) who reported having received a Pap test within the last 3 years. Results: Of all women (n=252 391), 72 366 had received a Pap test, and 32 935 of those women (45%, or 12.5 million, weighted) had a prior hysterectomy. We found that age, race/ethnicity, marital status, family income, health status, time since last routine checkup, and health insurance coverage were all significant predictors. Black, non-Hispanic women were 2.23 times more likely to receive Pap testing after a hysterectomy than white women (OR, 2.23; 95% confidence interval [CI], 1.99 to 2.50). Similarly, the odds for Hispanic women were 2.34 times higher (OR, 2.34; 95% CI, 1.97 to 2.80). The odds were also higher for those who were married (OR, 1.17; 95% CI, 1.08 to 1.27), healthier (OR, 1.24; 95% CI, 1.14 to 1.35), and had health insurance (OR, 1.54; 95% CI, 1.28 to 1.84), after controlling for confounders. Conclusions: We conclude that women may potentially receive Pap tests even if they are not at risk for cervical cancer, and may not be adequately informed about the need for screenings. We recommend strategies to disseminate recommendations and information to patients, their families, and care providers.

웹서비스 보안의 표준화

서문석 대불대학교 2002 論文集 Vol.8 No.1

The security services like authentication, confidentiality and integrity are needed indispensably to build up an application service based on the web technology that is occupied as a core skill to construct electronic commerce system that will be activated in recent. According to the absence of standardization about web services security, the computer resources of web services providers and users are wasted as installing many security modules that have same functions. In the authentication service using the digital signature, when a dispute arises between the two parties that are involved in a transaction, the currently adapted web services security models wouldn't provide easily the mechanism that are required by the trusted third party. Now, the complicated structure and circumstance of web service evolved rapidly demand something exceeding the present simple security protocols. In this paper, we'll look all around the problems brought about from the absence of security models and standardization for the web services. To meet the current situation about web services security, we'll also research the foreign countries' moving for the standardization of web services security and propose the proper security models and standardization components for the domestic web services security.

정보보안 실습을 위한 시스템 구성 방법

서문석 대불대학교 2003 論文集 Vol.9 No.1

The model of system construction for practice room of department of information security is not suggested yet. The students majoring in the security are sharing computers constructed in the same class room with many other students majoring in IT related sciences. So, they don't get the full benefit of the security practies. In this paper, I suggest the system construction scheme consisting of network part, system part, and application program configuration part for the practice room to effectively share computers between students of information securoty and others. I hope that the adaptation of this scheme for construction of computer practice room comes in pretty handy for all students to develop the skill of the computer.

Demographic and Survivorship Disparities in Non–muscle-invasive Bladder Cancer in the United States

서문석,James R. Langabeer II 대한예방의학회 2018 Journal of Preventive Medicine and Public Health Vol.51 No.5

Objectives: To examine survivorship disparities in demographic factors and risk status for non–muscle-invasive bladder cancer (NMIBC), which accounts for more than 75% of all urinary bladder cancers, but is highly curable with early identification and treatment. Methods: We used the US National Cancer Institute’s Surveillance, Epidemiology, and End Results registries over a 19-year period (1988-2006) to examine survivorship disparities in age, sex, race/ethnicity, and marital status of patients and risk status classified by histologic grade, stage, size of tumor, and number of multiple primary tumors among NMIBC patients (n=29 326). We applied Kaplan- Meier (K-M) and Cox proportional hazard methods for survival analysis. Results: Among all urinary bladder cancer patients, the majority of NMIBCs were in male (74.1%), non-Latino white (86.7%), married (67.8%), and low-risk (37.6%) to intermediate-risk (44.8%) patients. The mean age was 68 years. Survivorship (in median life years) was highest for non-Latino white (5.4 years), married (5.4 years), and low-risk (5.7 years) patients (K-M analysis, p<0.001). We found significantly lower survivorship for elderly, male (female hazard ratio [HR], 0.96), Latino (HR, 1.20), and unmarried (married HR, 0.93) patients. Conclusions: Survivorship disparities were ubiquitous across age, sex, race/ethnicity, and marital status groups. Non-white, unmarried, and elderly patients had significantly shorter survivorship. The implications of these findings include the need for a heightened focus on health policy and more organized efforts to improve access to care in order to increase the chances of survival for all patients.

美軍政期 對日軍政貿易과 綿紡織産業

서문석 한일경상학회 2021 韓日經商論集 Vol.90 No.-

Purpose: This study examined the impact of the Military Government’s trade with Japan during the U.S. Military Government period (1945.9-1948.8) on South Korea’s cotton textile industry. Through this, we understood the situation of the cotton textile industry, South Korea’s representative sector, and looked at the impact of the U.S. Military Government’s import policy on the cotton textile industry and companies in the South Korea shortly after the collapse of the colonial economy. Research design, data, and methodology: South Korea’s colonial economic system, which had been built around the munitions industry, collapsed when its colonial rule ended. Most factories stopped procuring raw materials and components, and the Japanese-owned company’s operators disappeared. The South Korean economy was paralyzed when workers left the plant that stopped operating. When the Cold War began, the U.S. military government in South Korea expanded its trade with Japan through GHQ. Machinery imported from Japan by the U.S. military government included parts related to cotton spinning. Parts and consumables of cotton spinning facilities imported from Japan were distributed to vested textile factories under the control of the U.S. military government. South Korea’s cotton textile industry, which suffered from a shortage of cotton parts and supplies, repaired a considerable number of facilities in 1947. At that time, representative large-scale vested textile factories began to increase efficiency in terms of facilities, operations, raw materials, and labor. Results: The U.S. military government restored part of the dismantled colonial economic system through military trade with Japan and restored Korea-Japan economic relations. The U.S. military government's move was revealed when the Delegation of Korea to Japan was established and the Korea-Japan trade agreement was signed under the leadership of GHQ in 1949, which eventually contributed to the signing of the Korea-Japan Agreement in 1965. Implications: In conclusion, the military government’s trade between Korea and Japan during the U.S. Military Government period played a role in expanding the colonial economic relationship to after Liberation. In addition, it provided the prototype of the cooperative relationship established by Korean and Japanese companies after the normalization of diplomatic relations between Korea and Japan
