Purpose: To assess the feasibility and safety of performing percutaneous radiofrequency ablation with cooled-tip electrode of kidney tissue in rabbits, and to evaluate the ability of CT to reveal the appearance and extent of tissue necrosis during follow-up after the thermal ablation. Materials and Methods: Using ultrasound guidance, a 17 G, cooled-tip electrode was inserted into the right lower portion of the kidney in 26 New Zealand White rabbits. Radiofrequency was applied for 2 min.. Biphasic helical CT scanning was used to assess tissue destruction and the presence or absence of complications immediately after the procedure and at 24 hr, 2days, 3days, 1week, 2weeks, 3weeks, 4weeks, 5weeks, 6weeks and 7 weeks. This study comprised three phases: an acute phase {immediately killed: N=10}, a subacute phase {after at 24 hr(n=3), 2days(n=3), 3days(n=1): N=81 and a chronic phase {after at 1week(n=4), 2weeks(n=2), 4weeks(n=1), 7weeks(n=1): N=8}. The animals were killed after CT, and their kidneys were histopathologically examined. Radiologic-pathologic correlation for lesion size and configuration was performed. Results: Ultrasound-guided radiofrequency ablations of the lower pole of the kidney were technically successful in each instance. Contrast-enhanced biphasic helical CT revealed regions of hypoattenuation devoid of parenchymal enhancement, which was closely correlated with true pathologic lesion size (r = 0.884; p > 0.05). In subacute and chronic models, the ablated lesion showed gradual spontaneous resorption with perilesional calcifications on CT scans. Histopathologically, in acute phase, the ablated lesions showed coagulative necrosis and infiltration of inflammatory cells, and in chronic phase, the lesion showed clear cut necrosis of glomeruli, tubules and renal interstitium with diminishing inflammatory response and peripheral fibrotic tissue formation. Conclusions: Ultrasound-guided renal radiofrequency ablation is technically feasible and safe. In addition, the avascular lesion measured on contrast-enhanced helical CT closely correlated with the size of ablated tissue; therefore contrast-enhanced CT could be used for serially monitoring the effect of radiofrequency ablation. In the future, RF ablation may offer an alternative treatment option for renal cancer.

김상원 서울대학교 대학원 2013 국내석사

이 연구는 공력 어드미턴스 함수를 고려한 시간영역 버페팅 해석방법을 제시한다. 주파수 의존적인 공력 어드미턴스 함수와 플러터 계수를 시간영역에서 고려하기 위해서 푸리에 급수를 이용하였다. 유리 함수를 이용한 접근 방법을 기준으로 하여, 푸리에 급수를 이용한 방법의 타당성을 검증한다. 실제 교량단면을 이용하여 공력 어드미턴스 함수가 실험을 통해서 추출된다. 이 측정된 공력 어드미턴스 함수는 유선형의 에어포일 단면으로부터 이론적으로 유도된 Sears 함수와는 다른 양상을 보인다. 푸리에 급수 전개를 이용하면 측정한 공력 어드미턴스 함수를 성공적으로 근사할 수 있다. 제시된 방법을 유한요소 전교 모형에 적용하여 버페팅 해석을 수행하고, Sears 함수와 측정된 공력 어드미턴스 함수를 각각 적용하여 응답을 구한다. 서로 다른 어드미턴스 함수를 적용하여 얻은 응답에 차이에 대해서 논의한다. A time-domain buffeting analysis considering aerodynamic admittance function is presented. The Fourier series approach (FSA) is adopted and extended to consider frequency-dependent aerodynamic admittance function and self-excited force. This adopted method is verified by comparing with a conventional method, the rational function approach (RFA). The admittance function of a bridge deck is extracted from experiments. The admittance function measured from the experiment showed difference with theoretical Sears’ function for airfoil cross-sections. This measured aerodynamic admittance function is approximated successfully by FSA. The introduced scheme is applied to the full FEM model of a cable-stayed bridge. Comparison of the response from the Sears’ function and experimentally extracted admittance function is dis cussed.

김상원 성균관대학교 일반대학원 2010 국내석사

The purpose of this study was to explore the feasibility of using the ICAST-R in assessing the level of violence and abuse experienced during childhood. The ICAST-R (ISPCAN Child Abuse Screening Tool- Retrospective version) was modified to meet the cultural context of Korea. ICASTST was developed by ISPCAN(International Society for the Prevention of Child Abuse and Neglect), in response to the UN Violence Study, drawing experts together from all over the world. To this end, the following research questions were set. First, what is the validity of ICAST-R? Second, what is the reliability of ICAST-R? Third, what is the prevalence of child abuse for Korean youth aged 18-24 years using the ICAST-R? The ICAST-R was translated into Korean and back-translated to English. Survey of focus groups, one consisting of 10 professionals and another consisting of 10 college students were conducted to assess if the ICAST-R was suitable for screening child abuse. Consequently, the ICAST-R was modified to meet the cultural context. The final version of the ICAST-R was administrated to 450 participants aged 18-24 years from the following sub-groups: educational institution, work place, clinical setting, of which 379 questionnaires were analyzed. Internal consistency and t-test were conducted to verify reliability and validity of ICAST-R. Descriptive analysis, chi-square test, multiple response analysis, and crosstabulation analysis were conducted to assess the prevalence of child abuse. The results of the study are as follows: First, ICAST-R was assessed as an appropriate tool for screening child abuse based on the focus group interview. Several items of the leaf-questions were revised to meet the cultural context. Statistical significant differences were found within interpersonal problems according to physical abuse and emotional abuse. Second, the internal consistency(as measured by Cronbach's 𝑎) for ICAST-R was .703, with .570 for physical abuse, .665 for emotional abuse, and .530 for sexual abuse. Third, the most frequently reported behavior for each type of child abuse was 'hit or punched' at 26.9%, 'insulted or criticized' at 25.6%, and 'someone exposed genitals' at 25.9%. There were gender differences in emotional abuse and sexual abuse, and location differences in sexual abuse. The most frequently responded in relation to frequency and experience period was '1 or 2 times' and 'between ages 14-17'. 'Boy at school(around their age or younger at the time of the incident)' was more most frequently reported as perpetrators of physical abuse, ‘Older male school mate(5 or more years older at the time of incident)' was more frequently reported as perpetrators of various acts of physical abuse, compared to parents. For emotional abuse, peers at school were most frequently reported perpetrators. Older male stranger was ranked the highest, with boy friend/ ex-boyfriend, and male in their neighborhood being next in sexual abuse. Those who reported forced to having sexual intercourse most frequently identified girls at school and girl friend/ ex-girl friend. It was notable that 'cyber/internet' was also reported as perpetrator of emotional and sexual abuse. Of those respondents who did not experienced physical abuse or emotional abuse, 30.7% and 5.9% respectively said that it was discipline and it was reasonable and justified. In addition, those abused physically or emotionally perceived that their experience was about the same as most children around their age. The sexually abused usually disclosed their unwanted sexual experience to their mother, and within one day regardless of who they disclosed it to. When asked about their reaction, 85.7% of respondents responded 'they believed me and supported me'. In conclusion, this study was able to confirm the feasibility of the ICAST-R in the Korea and to propose targeted intervention programmes. 본 연구는 아동이 경험하는 폭력실태를 알아보고자 ISPCAN이 전 세계 학대 전문가들의 참여를 도모하여 공동으로 개발한 ICAST-R(ISPCAN Child Abuse Screening Tool- Retrospective version)을 우리나라의 사회․문화적 맥락에 적합하게 수정하고, 본 도구가 우리나라에 적용 가능한지를 살펴보았다. 이를 위하여 설정한 연구문제는 다음과 같다. 첫째, ICAST-R의 타당도는 어떠한가? 둘째, ICAST-R의 신뢰도는 어떠한가? 셋째, ICAST-R을 사용하여 본 우리나라 만 18-24세의 아동기 학대경험 현황은 어떠한가? 포커스 그룹으로 전문가와 대학생 각 10인을 선정하여 ICAST-R이 우리나라 아동기 학대경험 선별에 적합한지 여부, 문항 이해도, 우리나라의 특수성을 반영하기 위해 추가사항 여부에 관해 인터뷰를 실시하였다. 만 18-24세 450명을 하위집단: 교육기관, 직장, 치료 및 상담기관으로 나누어 자료를 수집하였으며, 불성실한 응답 및 연령범주에 부합하지 않은 71명을 제외한 379명을 최종적으로 분석하였다. 자료분석은 SPSS program을 사용하였다.

김상원 성균관대학교 일반대학원 2011 국내석사

본 논문에서는 차세대 이동 통신 시스템에서의 통신 시스템의 다중화와 펨토셀 수의 증가로 인한 핸드오버 횟수 증가를 줄이기 위한 기법을 제안한다. 핸드오버 횟수가 증가할수록 핸드오버를 위한 시그널링 메시지로 인한 코어 시스템의 부하 및 핸드오버 실패로 인한 호 끊김 현상이 발생할 확률이 증가하게 된다. 본 논문에서는 단말 입장에서 히스테리시스 값과 타임-투-트리거 값을 고정된 값이 아닌 적응적으로 적용하는 두 가지 방식을 제안한다. 첫번째로 핸드오버 목표 셀들의 수신 신호 세기의 변화량을 분석한 후 히스테리시스 값과 타임-투-트리거 값을 조절해주어 이동 단말이 앞으로 움직여갈 확률이 높은 기지국으로 핸드오버하게 유도해주는 기법이다. 두번째로 개방형 펨토셀로의 불필요한 핸드오버를 방지하기 위해서 히스토리 기반 블랙 리스트 기법을 사용하여 과거 짧은 시간 머물렀던 펨토셀의 히스테리시스 값과 타임-투-트리거 값에 패널티를 주어 핸드오버를 일정시간 동안 하지 않게 하는 기법이다. 본 논문에서 첫번째 제안하는 기법인 수신 신호 세기를 통한 예측기법을 통해 2~14%의 핸드오버 감소를 얻었으며, 두번째 기법을 통해 34%의 핸드오버 감소 효과를 확인할 수 있었다. Lately evolution of the third generation (3G) mobile communication systems has been a major issue in the third generation partnership project (3GPP) group. For this purpose, 3GPP started the project, evolved universal mobile telecommunication system (UMTS) terrestrial radio access (UTRA) and UTRA Network (UTRAN), in late 2004, which is also called 3G long term evolution (LTE). Femtocell is an attractive solution for operators to improve indoor coverage and network capacity in LTE networks. The evolved Radio Access Network (RAN) involves a new radio interface based on OFDM technology and a radically different RAN architecture, where radio functionality is distributed into the base stations. The distributed nature of the RAN architecture calls for new radio control algorithms and procedures that operate in a distributed manner, including a distributed handover scheme as well. The most important aspects of the handover procedure in LTE has been already settled in 3GPP except a few details. One problem arising from new RAT system is the unnecessary occurrences of handovers that lead to excessive resource consumption. To avoid this, a suite of algorithms need to be deployed to limit the number of handovers. In this paper, we propose a hard handover scheme which adaptively decides important handover parameters such as hysteresis and time-to-trigger values considering the patterns of received signal strength (RSS) and lists of handover history, thus it is used to decide the handover trigger time. As a result, the handover rate using the proposed scheme based on RSS has decreased by 2~14%. the handover rate using the proposed scheme based on handover history has decreased by 34%. It is shown that the adaptive time-to-trigger and hysteresis scheme, handover rate is decrease while keeping the call drop rate.

김상원 충북대학교 2014 국내박사

Diabetic retinopathy is a serious and common complication of diabetes mellitus. If it is detected early by regular retinal examinations it can be treated and blindness can be prevented or delayed. In Korea, diabetes mellitus patient should visit ophthalmologist to evaluate diabetic retinopathy and the retinal examination rate is lower than the developed countries. This study was performed for the purpose of estimating the cost-utility analysis of early diagnosis and treatment of diabetic retinopathy depending on the screening strategies. The screening strategies were as follows: no screening; opportunistic examination by ophthalmologist; systematic fundus photography; systematic examination by ophthalmologist. Each of strategies had 10,000 people of 40-year-old adults with newly diagnosed diabetes mellitus which were set to the hypothetical cohort. Markov process model was developed to estimate the cost and quality-adjusted life years(QALY) during 40years analysis period or until blindness. From the perspective of the payer system, the incremental cost-effectiveness rate(ICER) of opportunistic examination was 48,961,339 and that of systematic photography was 43,575,592 so opportunistic examination could be weakly dominated. After exclusion of opportunistic strategy, the ICER of systematic photography was 45,588,788 and that of systematic examination was 308,193,813. From the perspective of the health care system, the ICER of opportunistic examination was 62,369,412 and that of systematic photography was 54,939,598 so opportunistic examination could also be weakly dominated. After exclusion of opportunistic strategy, the ICER of systematic photography was 57,716,867 and that of systematic examination was 419,989,046. According to the results of this study, the systematic strategy is preferable to the opportunistic strategy from the perspective of the payer system and the health care system. Although systematic examination can be higher utility than systematic photography, additional higher cost needs an external threshold to judge its worth. The results of this study might be used one of basis for rational decision making in choosing alternative strategy for diabetic retinopathy screening policy.
