최근 소프트웨어 개발 방법론의 발전과 함께 소프트웨어의 취약성을 제거하기 위한 방법론이 중요한 이슈로 대두되고 있다. 취약성을 제거하는 것은 소프트웨어의 안전성과 질적 향상에 기여할 수 있다. 이미 완성 단계의 소프트웨어에 대한 취약성을 분석하고, 제거하는 것은 코딩 단계에서 취약성 검사를 수행하는 것에 비해 비효율적이다. 개발 초기 단계에서부터 취약성을 제거하기 위해서는 컴파일 단계에서 취약성 검사가 수행되어야 한다. 본 논문에서는 기존의 안전한 자바 코딩 규약을 분석하고, 코딩 규약명세서를 이용하여 소프트웨어의 취약성을 분석할 수 있는 취약성 분석기를 설계한다. 제안한 취약성 분석기는 정형화된 컴파일러 방법론을 적용하였기 때문에 향후 컴파일 단계에서 취약성을 분석할 수 있는 기반 자료로 활용할 수 있다. 향후에는 자바 코딩 규약을 보완하고, 취약성 분석을 컴파일 단계에서 수행할 수 있도록 통합하는 기술에 대한 연구가 진행되어야 한다.

Purpose: This study was to evaluate the effect of arterial embolization on survival in patients with pelvic bone fractures and arterial bleeding. Methods: From January 2001 to December 2007, in all, 18 patients with pelvic bone fractures that had been treated with interventional arterial embolization were included in this retrospective study. The Injury Severity Score (ISS), the Revised Trauma Score (RTS), the initial hemodynamic status, the blood gas analysis, blood transfusion data, and mortality were the main outcome measurements. Results: Pelvic bone fractures were classified into lateral compression (LC), antero-posterior compression (APC), vertical shear (VS), and combined (CM) type according to the Young-Burgess classification. The Survivor group included 11 patients (61.1%), and the non-survivor group included 7 patients (38.9%). The mean ages for the survivor and the non-survivor groups were 40.0 and 45.6 years (p=0.517). The types of pelvic bone fractures were LC 11 (61.1%), APC 6 (33.3%), and VS 1 (5.6%): LC 7 (63.6%), and APC 4 (36.4%) in the survivor group and LC 4 (57.1%), APC 2 (28.6%), and VS 1 (14.3%) in the non-survivor group. The internal iliac artery was the predominant injured vessel among both the survivors (n = 5, 45.5%) and the non-survivors (n = 4, 57.1%). No differences in initial blood pressures, ISS, and RTS existed between the two groups, but the arterial pH was lower in the non-survivor group (pH 7.09 (±0.20) vs 7.30 (±0.08), p=0.018). The number of transfused 24-hour units of packed RBC was greater in the non-survivor group (24.1±12.5 vs 14.4±6.8, p=0.046). Conclusion: No differences in initial blood pressure and trauma scores existed between survivors and non-survivors with pelvic bone fractures, who had been treated with arterial embolization, but arterial pH was lower the in non-survivors.

Purpose: The purpose of this study is to analyze the clinical characteristics of anaphylaxis and anaphylactic shock caused by bee venom. Methods: We retrospectively collected the data of the patients who experienced anaphylaxis caused by natural bee sting or acupuncture using bee venom from January 1999 to December 2008. Seventy subjects were divided into the shock and non-shock groups. The clinical characteristics, sources of bee venom, treatments and outcomes were compared between the two groups. Results: The mean age of the subjects was 45.5 ± 16.3 years old and the number of males was 44 (62.9%). There were 25 patients in the shock group and 45 in the non-shock group. The age was older (p=0.001) and females (p=0.003) were more frequent in the shock group. Transportation to the hospital via ambulance was more frequent in the shock group (p<0.001). No difference was found in species of bee between the two groups. The cephalic area, including the face, was the most common area of bee venom in both groups. Anaphylaxis caused by bee sting commonly occurred between July and October. Cutaneous and respiratory symptoms were the most frequent symptoms related to anaphylaxis. Cardiovascular and neurologic symptoms were more frequent in the shock group. The amount of intravenously administered fluid and subcutaneous injection of epinephrine were much more in the shock group than that in the non-shock group. Conclusion: Older age was the factors related to anaphylactic shock caused by bee venom. Further validation is needed to evaluate the gender factor associated with shock.

Background: Food-induced anaphylaxis accounts for the most proportion of the anaphylaxis treated at the emergency department. In Korea, reports regarding food-induced anaphylaxis are very few. Objective: The purpose of this study is to evaluate the general characteristics and clinical features of food-induced anaphylaxis in the southeastern coasted area of Korea. Method: A retrospective study was conducted on the patients visiting the emergency department at Ulsan University Hospital between 2000 and 2009. We reviewed patients` medical records diagnosed with food-induced anaphylaxis and other related diseases. Result: We identified 66 patients with food-induced anaphylaxis. The mean age of the patients was 41.9 years (SD±13.8). The inciting agent included seafoods in 29 cases (43.9%), wheat in 5 cases (7.6%), pork meat in 5 cases (7.6%), buckwheat in 2 cases (3.0) and cowmilk in 2 case (3%). Mucocutaneous manifestations were the most common, followed by respiratory, cardiovascular, gastrointestinal and neurologic manifestations in decreasing order of frequency. There were 32 patients (48.5%) with moderate anaphylaxis and 51.5 patients (51.5%) with severe anaphylaxis. There were no significant correlations between severity and epidemiologic factors including age, sex, comorbid disease and smoking. Conclusion: We found that seafoods are major causative agents of food-induced anaphylaxis in the southeastern coastal area of Korea. Therapeutic fluid was more frequently required, and the time from arrival at the emergency department to discharge was longer in patients with severe anaphylaxis.

Soybean nuclear extracts were prepared to detect SEF3(soybean embryo factor 3), which is presumed to be a trams-acting factor for the expression of the soybean β-conglycinin α` subunit gene. To increase the specific activity of DNA probe during labeling with [α-^(32)P]dATP, dATP was added to a final concentration of 1.1 mM during the chase reaction. It results in approximately four-fold increase of specific activity of the DNA probe. Effects of several modifications in preparation of soybean nuclear extracts were examined. It was found that glycerol is effective to stabilize SEF3 during the preparation of nuclear extracts and polyethylenimine could be used to increase the specific activity of SEF3 in nuclear extracts.

The peach pyralid moth (Dichocrocis punctiferalis) is reported as important pest insect to chestnut fruits in Asia including Korea. For seasonal occurrence of D. punctiferalis in 1996, 1998 and 1999, D. punctiferalis adults were collected by light trap and sex pheromone wing trap in the chestnut orchard. Also, damaged rate of chestnut fruits were examined each collecting site. In 1996, according to examination by using light trap at three different site in Kongju, the occurrence peak of 2nd generation of D. punctiferalis adults was early August. Collected individuals after September were considered as 3rd generation. Damaged rate due to maturation type was 26.5% averagely. The order of damaged rate were early, late and middle maturation type as 35.04%, 19.35% and 26.03%, respectively. Using synthetic sex pheromone trap at Kongju, Cheungyang and Buyeo in 1998, occurrence peaks were occurred mid-August to 2nd generation and late September to 3nd generation in Kongju. However, from early-August to late-September 5 peaks were occurred sequentially in Cheungyang. Second generation adults were occurred in mid-August and 3rd ones were occurred from late-September to early-October in Buyeo. In 1999, occurrence peaks of 3rd generation were early, middle and late September in Kongju, Cheungyang and Buyeo respectively. Damaged rate were 6.8%, 6.6% and 15.3% in Kongju, Cheungyang and Buyeo, respectively. Damaged rate order due to variety were Eunki, Chukpa, Danpa, Bokpa, Wangjung, Byunggo57, Yuoma at Buyeo and were Chukpa, Dukmyung, Byunggo57 at Cheungyang in 1999. Damage rate of chestnut were different with variety. Eunki and Chukpa in Buyeo and Chukpa and Dukmyung in Cheungyang were more damaged by D. punctiferalis, respectively.

본 실험에서는 대두 β-conglycinin의 α'subunit 유전자의 발현에 관여하리라 생각되는 대두 배 인자 3의 역가를 함유하는 대두 핵 추출물 조제 방법에 대하여 조사하였다. 역가 조사를 위한 DNA의 표지반응 후에 추가로 1mM dATP를 첨가하여 반응을 지속한 경우가 첨가하지 않은 경우보다 2배 높은 방사능 역가의 DNA 탐침을 얻을 수 있었다. 이러한 DNA 탐침을 이용하여 핵 추출물 조제방법에 따른 대두 배 인자 3의 역가를 gel mobility shift assay로 조사한 결과, 조제 중 glycerol의 첨가가 배 인자 3의 역가를 안정화시켰고, polyethylenimine을 이용한 대두 핵 추출물 조제법이 배 인자 3의 비역가를 증가시키는 데 이용될 수 있음을 알 수 있었다. Soybean nuclear extracts were prepared to detect SEF3(soybean embryo factor 3), which is presumed to be a trans-acting factor for the expression of soybean β-conglycinin α' subunit gene, in gel mobility shift assay using the DNA probe containing two AACCCA hexanucleotides. To increase the specific activity of DNA probe during labeling with [α-32P]dATP, dATP was added to a final concentration of 1.1 mM during the chase reaction. It results in twofold increase of specific activity of the DNA probe. The effects of several modifications in preparation of soybean nuclear extracts were examined. It was found that glycerol is effective to stabilize SEF3 during the preparation of nuclear extracts and polyethylenimine could be used to increase the specific activity of SEF3 in nuclear extracts.
