Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

This study was performed to investigate whether TiN coating could reduce the cytotoxicity of electroplated orthodontic stainless steel wire which had been known to be cytotoxic. Nickel plating was done on stainless steel wire using a electroplating technique. Some of the electroplated wires were coated by TiN film and 4 groups of specimen were prepared (Non-coated electroplated wire, TiN coated electroplated wire, Titanium which was known to have no cytotoxicity, Copper which was known to have high cytotoxicity). Each wire was incubated for 72 hours on the medium. The release of the metal ion was measured by ICP-AES. The incubated medium was diluted 75 %, 50%, 25 % and added on each microplate with Balb/c 3T3 mouse fibroblast for MTT analysis and compared with medium only. Through the measuring of the change in absorbency value of each wire group and the difference of absorbency value according to change of dilution, following results were obtained. 1. The results of ICP-AES analysis showed that lots of nickel ions were isolated from non-coated wires but not isolated from TiN coated wires. 2. The inverted microscope showed that there was a decrease in cell count in non-coated wires but no significant change in TiN coated wires. 3. The results of MTT analysis showed that there was no difference in the absorbency value between TiN coated wires and medium and between titanium and medium but the absorbency value of non-coated wires and copper were lower than that of medium only at all dilution and showed statistically significant differences(p<0.001). 4. Assessment as per ISO 10993, part 5, non-coated wires and copper investigated corresponded to "moderately cytotoxic" and "highly cytotoxic" ; whereas titanium and TiN coated wires were alloted to "non-cytotoxic". The results of the present study indicate that the cytotoxicity of the electroplated orthodontic wire can be changed from "moderately cytotoxic" to "nontoxic" by TiN coating and electroplated wire can be used clinically without the concern of cytotoxicity.

Objectives : Diffuse tensor imaging (DTI) was applied to explore the difference in regional distribution and extent of white matter (WM) abnormalities in boys with Attention-deficit/hyperactivity disorder (ADHD) versus boys with comorbid ADHD and tic disorders. Methods : Fifteen boys with ADHD (mean age 9.3 +1.8), 24 ADHD boys with chronic tic disorder or Tourette's disorder(9.9 =b 1.2) and 9 age-, gender-matched controls (9.2 d= 1.8) received DTI assessments. Fractional Anisotropy (FA) maps of WM were compared between groups with a voxel-wise analysis after intersubject registration to MNI space. Results : Bo groups, ADHD group and ADHD with tic disorder group, commonly showed decreased FA than healthy control group in left cerebellar middle peduncle and right frontal lobe, increased FA in right middle occipital WM. In the common areas of left cerebellar middle peduncle and right middle occipital WM, comorbid group showed broader areas of significant FA. The comorbid group also showed increased FA in right cerebellar peduncle, additionally. Conclusion : The findings in ADHD group support previous ADHD hypothesis of the functional abnormalities in corticocerebellar circuit, and suggest that ADHD might have more complicated pathology of neuronal circuit including occipital visual system. The comorbid group showed common areas of overlapping but more extensive abnormalities and also had additional WM abnormalities. ADHD with chronic tic disorders may represent a severe form of ADHD with additional regions of abnormal connectivity.

저자들은 호흡곤란, 흉부불쾌감, 심계항진 등을 주소로 내원한 환자에서 경흉부 및 경식도 심초음파 검사상 주폐동맥에서 이완기에 전행하는 지속적인 혈류의 흐름을 관찰하고, 관상동맥 조영술을 통해 좌전하행지 중간부위와 우관상동맥 근위부에서 각각 기시하여 공통경로를 이루면서 주폐동맥으로 유입되는 양측성 관상동정맥루를 보이는 드문 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. A coronary arteriovenous fistula is infrequently encountered vascular communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula constitutes an uncommon subgroup of coronary arteriovenous fistulas. A 69 year-old female patient presented with chest discomfort, palpitation, and dyspnea. In the echocardiography, doppler color flow imaging visualized abnormal flow signals with mosaic appearance in the main pulmonary artery during diastolic phase. Coronary angiography revealed arteriovenous fistula arising from the left anterior descending artery and the right coronary artery. Both coronary arteriovenous fistulas drained into the main pulmonary artery. We report a case of bilateral coronary arteriovenous fistula that was confirmed by echocariography and coronary angiography.

무선 환경에서 안전한 종단간 보안을 제공하는 AWTLS(Alternative Wireless Transport Layer Security) 프로토콜 : AWTLS(Alternative Wireless Transport Layer Security) Protocol

최진규,이헌길 강원대학교 정보통신연구소 2002 정보통신논문지 Vol.6 No.-

The WAP is a set of protocols that optimizes standard TCP/IP protocols, for use under the low bandwidth, high latency conditions often found in wireless networks. In WAP, WTLS(Wireless Transport Layer Security) is a subprotocol that it has been suggested for security communications. This protocol is a modified version of the TLS(Transport Layer Security) appropriate for wireless networks. In the data exchange between WTLS and TLS protocol, the message transmitted between the handset and the server is unencrypted for a very brief moment inside the WAP gateway. Even though the interval time the message remains unencrypted is very short, he or she who has an administrator account can attempt to view the unencrypted message. Therefore, in this paper, we propose the safe end-to-end security model, which is called AWTLS(Alternative Wireless Transport Layer Security). The proposed AWTLS can not only prevent the gateway from viewing the uncrypted message, but also reduce the encryption/decryption overhead of the mobile terminal.

By performing dc analysis based on device simulation utilizing a two dimensional device simulator incorporating the lattice heat generation model, we compare the breakdown characteristics of the conventional NMOS structure and the pnpn thyristor structure for ESD protection. From the analysis, we confirm that, due to the reduction of holding voltage, the pnpn structure with much smaller device width can provide the similar level of protection provided with the NMOS structure. Adopting this kind of protection devices is expected to be able to reduce the parasitic capacitance added to the input node considerably, and therefore to be suitable for RF IC applications. By comparing the characteristics of various kinds of pnpn devices with structure variations, we figured out the device structure most suitable for ESD protection.
