강현식(Hyunsik Kang),김정덕(Jungduk Kim) 한국전자거래학회 2015 한국전자거래학회지 Vol.20 No.2

정보보호 전담조직은 IT 부서 산하에 편성되어있는 것이 일반적이었으나 정보보호의 중요성이 증대됨에 따라 전사적 보안을 위한 정보보호 전담조직의 편성이 중요한 이슈로 대두되고 있다. 국내 금융권에서도 전자금융거래법 개정안을 통해 CIO와 CISO를 분리하는 등 정보보호 전담조직의 분리에 대한 필요성이 증대되고 있다. 하지만 현재 정보보호 전담조직 하부구조에 대한 연구는 활발히 진행되고 있으나 편성방법에 대한 연구는 미흡하다. 따라서 본 논문에서는 효과적인 정보보호 전담조직의 편성을 위해, 상황적 접근방법을 통하여 기업의 비즈니스 위험도와 IT 의존도를 기준으로 정보보호 전담조직 편성모델을 제시하였다. 또한 정보보호 전담조직이 소속될 부서를 기획?조정 부서, 내부통제 부서, 내부관리 부서, IT 부서로 분류하고 각 부서에 편제되어있을 경우의 장단점을 분석하였다. Information security organization has normally been organized under the IT department. However, as the importance of information security has gradually increased, the way of information security organized for enterprise security management has become a noteworthy issue. The need for separation of Information security organization from IT department is growing, such as restriction on the concurrent positions in CIO and CISO. Nowadays there are many studies about Information security organization while relatively there has been minimal research regarding a departmentalization. For these reasons this study proposes a Information Security Departmentalization Model which is based on business risk and reliance on the IT for effectively organizing Information security organization, using Contingency theory. In addition, this study classified the position of Information security organization into Planning & Coordination, Internal Control, Management and IT and analyze the strengths and weaknesses of each case.

An experimental study was performed to investigate the structural behaviors of cold-formed carbon steel square hollow section columns to provide basic data of Korean design specifications for cold-formed steel structures. Specimens were fabricated with carbon steel square pipes for general structural purpose (SRT275). Main variables included the column length of 250mm, 1000mm and 2000mm, section dimension of 50x50mm and 75x75mm and section thickness of 2.0mm and 2.9mm. The initial imperfections of the specimen surface were measured and the material properties of these specimens satisfied the minimum requirement of Korean standards. All of the specimens or stubs with the column length of 250mm showed local buckling. The ultimate state of specimens with 1000mm and 2000mm column lengths were determined by local buckling or global buckling. Despite the large slenderness ratio, local buckling was observed in some specimens with a slender section element and a relatively large width-thickness ratio. Test results were compared with ultimate buckling strengths predicted by current design specifications of the Korean Design Standard (KDS), American Institute of Steel Construction (AISC), Eurocode 3 (EC3), and the American Iron and Steel Institute (AISI).

In the 60`s to 70`s, frame selection was a purely mechanical consideration almost entirely dominated by the optician and his subjective judgments. Toddy the cosmetic factor is predominant. The variety of frame color, materials, and style means that the main burden of selection has passed to the customer, leaving the optician control a subtle factor often difficult to exert. Common materials include nickel silver, Hi-nickel alloy, bronze, stainless steel, gold, gold plated, gold clad, copper beryllium, titanium and sometimes aluminium. In manufacturing of metal frames with the materials, even though fashion is the stimulant of consumer demand, all the metal frame for the prescription to refractive correction should be designed correctly styled eyewear which is cosmetically pleasing, functional correct, physically comfortable, mechanically and structurally perfectible, and temperamentally acceptable.

A Study on Selection of Core Services for Deciding ISMS Scope

Hyunsik Kang(강현식),Jungduk Kim(김정덕) 한국컴퓨터정보학회 2017 韓國컴퓨터情報學會論文誌 Vol.22 No.2

The first thing to be prioritized is to set the scope of the management system when establishing an information security management system for systematic and effective information security management. It is important to set the scope for an organization’s information security goals due to the scope affects the organization’s overall information security activities. If the scope is set incorrectly, it might become impossible to protect important services and therefore, the scope of the management system should be determined in consideration of the core business services of the organization. We propose a core service selection model based on the organization’s mission-critical service and high risk service in order to determine the effective information security management system scope in this paper. Core service selection criteria include the type of service, contribution to sales, socio-economic impact, and linkage with other services

In this cross-sectional study, we examined the effect of cardiovascular risk factors on cognitive impairment and depressive symptoms in older Korean women aged 60 years and older (N=3,034). Cardiovascular risk factors included smoking, heavy alcohol consumption, physical inactivity, underweight/obesity, unintentional weight loss. Cognitive impairment and depressive symptoms were assessed with Mini-Mental Status of Examination and Center for Epidemiological Studies of Depression 10, respectively. Logistic regression analyses showed that odds ratio (OR) of cognitive impairment was 2.79 (95% confidence interval, CI, 2.220∼3.515, p<0.001), 2.97 (95% CI, 2.323~3.793, p<0.001), and 4.38 (95% CI, 2.861~6.711, p<0.001) for one, two, and three and more risk factors. The ORs of one and two risk factors for cognitive impairment remained significant even after adjustments for age, body mass index, income, education, religion, type of house, impaired activities of daily living, fall experience, hospitalization, and medications. The OR of depression was 1.81 (95% CI, 1.439~2.272, p<0.001), 2.24 (95% CI, 1.757~2.585, p<0.001), and 3.44 (95% CI, 2.268~5.207, p<0.001) for one, two, and three and more risk factors. The ORs of one, two, three and more risk factors for depression remained significant even after adjustments for all the covariates.

Purpose: This study aimed to investigate the effect of cardiovascular disease (CVD) risk and physical fitness on cognitive impairment in Korean elderly women. Methods: In a cross-sectional design, a total of 308 Korean elderly women, aged 60 years or older, participated in this study. Measured parameters included the 10-year Framingham risk score (FRS), physical fitness (i.e., upper and lower body strength and flexibility and endurance), and cognitive performance based on Mini-Mental State Examination for dementia screening. The participants were classified as low (<10%) or intermediate and high (≥ 10%) risk groups based on the 10-year FRS and as unfit (lower 50%) or fit (higher 50%) on a composite z-score of physical fitness. Logistic regression was used to estimate the odd ratios (ORs) and confidence intervals (CIs) of cognitive impairment according to the 10-year FRS and physical fitness-based classification. Results: The low FRS/unfit and intermediate or high FRS/unfit groups had significantly higher risks of cognitive impairment (OR, 3.714; 95% CI, 1.324- 10.418; p=0.013 and OR, 11.345; 95% CI, 4.810-26.762; p<0.001, respectively) compared with the low FRS/fit group (OR, 1). In particular, the elevated risk of cognitive impairment remained significant (OR, 3.876; 95% CI, 1.400- 10.726; p=0.009) even after adjustments for covariates such as age, body mass index, education, and physical inactivity. Conclusion: The current findings suggest that an intervention targeting at both CVD risk reduction and physical fitness promotion is urgent as a preventive and/or therapeutic measure against declines in cognitive function in Korean elderly women.

The purpose of the study was to investigate whether or not physical activity (PA) and cardiorespiratory fitness (CRF) play independent roles for the development of metabolic syndrome (MS) in middle-aged women. A total of 79 apparently healthy women (mean age of 50.1±3.4 years; body mass index of 24.6±2.5 ㎏/㎡) were invited to participate in this study. Blood variables including glucose and lipoprotein-lipids were measured in fasting blood samples. Baseline PA levels were measured with an accelerometer for seven consecutive days, and CRF was estimated from a sub-maximal cycle ergometer test. From the current study, we found the following results. The optimal cut-off points of the daily PA and CRF for preventing the MS appear to be 9,820 steps/day and 27.6 ㎖/㎏/min, respectively, at least in this study population. With respect to the daily PA, the odds ratios of the MS were 1.0 for the active group and 9.1 for the sedentary group, respectively, even after adjusted for age, body mass index (BMI), percent body fat (%BF), waist, and VO2mx,. With respect to CRF, the odds ratios of the MS were 1.0 for the fit group and 0.9 for the unfit group, respectively, even after adjusted for age, BMI, body fat, waist, and PA. There were linear trends in the morbidity of the MS across PA levels; the higher the PA the lower incidence of the MS. Those relationships were independent of age, body fatness such as BMI, %BF, waist circumference, and CRF. There were similar trends in the MS morbidity across CRF levels; the higher the CRF the lower incidence of the MS. However, the magnitude of the trends was somewhat less than that of the trends-related to PA level. In summary, the findings of the current study suggest that PA plays a significant and independent roles in determining the incidence of the MS in middle-aged women.

인터넷의 급속한 발전으로 인해 네트워크를 통한 텍스트, 이미지, 사운드, 비디오 등과 같은 디지털 컨텐츠의 유통이 점차 대용량으로 변화하고 있다. 이러한 컨텐츠의 유통을 위해 쓰이는 URI는 텍스트의 한 페이지, 사운드 또는 비디오 클립, 정지 화상과 동영상은 물론 프로그램과 같은 컨텐츠를 인식하는데 쓰이고 URL을 이용하여 정보자원의 물리적 위치를 표시하는 문자열을 통해 정보자원에 접근하고 검색하게 된다. 하지만 휴대용 단말기를 이용하는 경우 단점이라 할 수 있는 입력기능의 제한으로 인해 정보이용이 쉽지 않기 때문에 정보 접근을 위한 새로운 URI 체계와 서비스 환경이 필요하다. 새로운 URI 체계에 하나의 대안으로 바코드나 특정 이미지와 같은 화상을 이용할 수 있는 방법이 있으며 이를 화상 URI로 체계화 시키는 작업이 필요하다. 본 논문에서는 ENUM과 화상인식 관련 기술들을 연구하고 ENUM서비스가 실용화될 경우 ENUM서비스와 연계하여 사용할 수 있는 화상 인식 URI용 인식코드를 제안한다.
