슬라이스의 유용성은 testing, parallel processor distribution, maintenance, debugging등에서 잘 알려져 있다. 슬라이스를 구하기 위한 기법은 자료 흐름 분석과 제어흐름 분석을 이용한 기존의 Weiser 방법과 PDG를 이용하는 방법이 있다. 본 논문은 기존의 방법보다 더욱 정확한 슬라이스를 구할 수 있는 PDG를 이용하여 슬라이서를 설계한다.

임익균,차현석,강원철,이상빈,한규성,Im, Ik-Gyun,Cha, Hyun-Seok,Kang, Won-Chul,Lee, Sang-Bin,Han, Gyu-Seong 한국문화재보존과학회 2021 보존과학회지 Vol.37 No.3

본 연구에서는 전국 및 지역별 지중 흰개미 정기 모니터링 실시 기관들의 결과보고서를 바탕으로 국내 목조문화재의 지역별, 지정별 지중 흰개미 피해 및 관리 현황을 파악하였다. 또한 조사 내용들을 바탕으로 GIS 프로그램을 이용하여 전국 2,805건의 조사 대상 목조문화재에 대한 지중 흰개미 가해흔 및 가해 진행 현황 지도를 제작하였다. 현황 지도 제작 결과, 2018년~2019년의 기간 동안 총 486건의 목조문화재에서 지중 흰개미 가해흔이 확인되었으며, 그중 143건(약 29.4%)에서 지중 흰개미 권역 유입 및 목부재 가해가 진행 중인 것으로 확인되었다. 위와 같이 조사된 피해 현황 자료의 접근성을 높이기 위하여 Map API를 활용한 웹 플랫폼 및 웹 어플리케이션을 제작하였다. 또한 기관별 결과보고서에서 확인된 지중 흰개미 모니터링 방안으로는 탐지견, 육안관찰, 예찰기, 극초단파 장비 등이 지중 흰개미의 유입 유무 파악 방안으로 적용되고 있으나 유입된 지중 흰개미 군체의 영역 범위를 판단할 모니터링 조사 방안은 현재 적용되고 있지 않은 것으로 확인되었다. 이에 따라 지중 흰개미 군체 모니터링 조사 시, 대상 목조문화재의 가해 영역 범위 산정 등 현황 파악을 위한 염색약 처리 및 Mark-Release-Recapture법의 적용이 필요할 것으로 판단된다. In this study, the status of damage by subterranean termites and their management according to the region and type of domestic wooden cultural properties were identified. This was based on the survey reports of agencies conducting regular nationwide and regional monitoring of subterranean termites. In addition, using geographical information system (GIS) based on the survey contents, a map was constructed of termite infestation and its progress on 2,805 wooden cultural properties that were surveyed nationwide. Based on the map produced, a total of 486 cases of termite infestation were confirmed in wooden cultural properties during 2018-2019, of which 143 cases (approximately 29.4%) were confirmed to be owing to the invasion of termites in the ground and infestation of wood materials. A web platform and an application using a mapping application program interface were created to increase accessibility to the investigated damage status data. The methods employed by each institution for investigating and monitoring the invasion of termites in the ground included the use of detection dogs, visual observation, installation of wood specimens made of pine, and microwave equipment. However, it was confirmed that monitoring and survey methods were not applied to determine the territorial range of the subterranean termite colonies. Accordingly, the use of dyeing and mark-release-recapture methods were deemed necessary to understand the current status, such as calculating the scope of the target wooden cultural property, when monitoring subterranean termite colonies.

PIFG 를 이용한 프로그램 슬라이싱 ; Jump 문을 중심으로

박재흥(Park Jae Heung),강원임(Kang Won Im),박중양(Park Joong Yang) 한국정보처리학회 1998 정보처리학회논문지 Vol.5 No.10

Program slicing is a technique to extract the statements which influence the value of a variable at a particular point of the program. It has been proposed that this technique is useful in debugging, optimization, program maintenance, testing, extracting reusable components and other applications including the understanding of the program behavior. This paper aims to address the problem of slicing programs with Jump-goto, break, continue- in C statements. It was found that previous slicing algorithms do not always generate semantically correct slices when applied to such programs. We, therefore, point out why the previous methods do not work in this more general setting, and describe our efficient solutions that compute more correctly executable slices for such programs.

프로그램 슬라이싱은 프로그램의 특정 위치에서 변수들의 값에 영향을 주는 문장을 추출하는 방법이다. 프로그램 슬라이싱의 유용성은 디버깅, 최적화, 프로그램 유지보수, 테스팅, 재사용 부품 추출 그리고 프로그램 이해를 포함하는 다른 응용 분야에 널리 알려져 있다. 본 논문은 C언어에서의 함수 호출이 존재하는 모듈간 프로그램 슬라이싱에 관한 연구이다. 기존의 모듈간 슬라이싱 알고리즘들은 함수의 호출 문맥 설명에 실패하거나 문장 기반 그래프를 사용함으로써 정확한 슬라이스 생성에 실패한다. 본 논문에서는 기존 방법들의 문제점을 지적하고, 시스템 정보 흐름 그래프 (System Information Flow Graph)를 이용하여 정확하고 수행 가능한 모듈간 슬라이스 생성 방법을 제안한다.

In order to design efficient air vaporizers the heat transfer coefficient of air side is a critical parameter. Air side heat transfer coefficient was estimated using experimental and numerical method in this study. Surface temperatures of tube and fin were measured in steady state condition. Heat transfer coefficient was estimated by computational heat transfer anlysis using the measured temperatures as boundary condition. The result gave the average heat transfer coefficient at the air side of the air vaporizer was around 7.6 W/m²·K

Purpose: This study was performed to evaluate clinicopathologic features in anal canal carcinoma. Methods: Among the 43 patients who were diagnosed with anal cancer at Kangnam St. Mary’s Hospital, from June 1990 to June 2008, 31 patients were analyzed retrospectively. Concurrent chemoradiotherapy was performed on twenty-one patients with anal cancer. Chemotherapy with 5-FU/mitomycin and radiotherapy were started at the same time. An external beam radiation dose to the primary lesion and pelvis was modified from 4,500 to 6,000 cGy. Results: Among the 31 patients with anal cancer, the dominant histologic type was squamous cell carcinoma (n=25), followed by adenocarcinoma (n=6). Twenty-nine (93.5%) of these cancers were located in the anal canal and 2 (6.5%) in the anal margin. Among the 25 patients with squamous cell carcinoma, 20 cases were treated by concurrent chemoradiotherapy. The 5-year survival rate among squamous cell carcinoma cases was 83.3% for the concurrent chemoradiation group and 50.0% for the no concurrent chemoradiation group, which was statistically significant (P=0.05). Among the squamous cell carcinoma patients, there was no significant difference in survival rates between concurrent chemoradiation group (n=17) and concurrent chemoradiation with surgical resection group (n=8) (87.5% vs 68.8%; P=0.596). Conclusion: In the squamous cell carcinoma treatment, concurrent chemoradiation therapy can offer better outcomes.

Purpose: Despite all developments in recent years, the choice of an adequate treatment for hemorrhoids remains a problem. Hemorrhoidal artery ligation and recto-anal repair (HAL-RAR) is a nonexcisional surgical technique for the treatment of hemorrhoids, consisting in the ligation of the distal branches of the superior rectal artery, resulting in a reduction of blood flow and decongestion of the hemorrhoidal plexus. The aim of this study was to present the early experience of treating hemorrhoids with HAL-RAR. Methods: Between December 2008 and November 2009, 70 consecutive patients with symptomatic hemorrhoids were treated with HAL-RAR. The patients underwent sonographic identification and suture ligation of 4 to 8 terminal branches of the superior rectal artery above the dentate line. Results: There were 33 males and 37 females (mean age, 49.72±14.1 years). The mean operative time was 43.8 minutes (25∼80 min). Most patients (=61, 87%) were without any complaint upon follow-up at 1 week. Nine patients presented with early complication: isolated pain in 1, anemia in 1, isolated bleeding in 1, voiding difficulty (over 1 day) in 2 and tenesmus (over 2 weeks) in 4. Conclusion: Based on our results we may conclude that HAL-RAR is a minimally invasive, safe and effective method and may offer an important alternative for the treatment of hemorrhoids. It may offer minimally postoperative pain, and early return of patients to their normal activities.

Primary lymphoma of the urinary bladder is a rare non-epithelial bladder tumor accounting for less than 1% of all bladder tumors. Approximately 17 cases of MALT lymphomas of bladder have been reported in the literature. Most reported MALT lymphomas of bladder have a female sexual preponderance with a mean age of 58 years with common presenting symptoms of hematuria, dysuria and urinary frequency. The reported prognosis of MALT lymphoma of the urinary bladder is excellent. We report a case of MALT lymphoma of urinary bladder in a 57-year-old woman patient who presented with a two-year history of persistent dysuria and urinary frequency. An intravenous pyelogram and cystoscopy revealed a 1 cm focal elevated lesion at the base of urinary bladder. The tissue obtained by transurethral resection (TUR) showed plasma cell infiltration consistent with low grade marginal zone B cell lymphoma. The immunohistochemical studies showed an immunoglobulin restriction to lambda light chain while the nested polymerase chain reaction analysis of the tissue showed a monoclonal Ig heavy-chain gene rearrangement. The clinical staging protocol revealed that the tumor was primarily arising from the urinary bladder with no evidence of other site involvements. The patient received radiation therapy of 3060 cGy in 17 fractions.
