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 designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

최윤정,방승규,김정진,도규영,백인호 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.4

연구목적 : 도파민계는 알코올 추구와 같은 알코올 의존증과 관련된 행동에 중요한 역할을 한다. Dopamine transporter(DAT1)는 신경연접부위에서 도파민 재흡수에 관여하여 도파민 활성을 종결시키는 물질로 알려져 있다. 그러므로, DAT1 유전자가 알코올 의존증에 대한 감수성에 영향을 줄 수 있다. DAT1 유전자는 다형성을 보이는 반복된 40개의 염기서열(VNTR)을 갖는다. 본 연구에서는 DAT1 유전자 다형성과 알코올 의존증 및 알코올 의존증의 임상변인과의 관련성에 대하여 알아보았다. 방 법 : 알코올 의존증 환자 94명과 정상대조군 113명을 대상으로 말초혈액을 채취하여 분리된 DNA의 DAT1 유전자를 DNA 중합효소연쇄반응으로 증폭하였다. 증폭된 산물을 15% polyacrylamide gel에서 전기영동하여 나타나는 띠의 크기에 따라 유전자형을 구분하였다. 자료의 통계적 처리는 Fisher's exact test, oneway ANOVA를 사용하였다. 결 과 : 환자군과 정상대조군의 유전자형은 모두 Hardy-Weinberg equilibrium의 예상치와 유의한 차이가 없었다. 대립유전자는 7 repeats, 9 repeats, 10 repeats, 11 repeats의 4가지 종류로 구분되었고, 유전자형은 7/7 repeats, 7/10 repeats, 9/10 repeats, 10/10 repeats, 10/11 repeats의 5가지 형태를 보였다. 환자군과 대조군간에 DAT1 유전자형 및 대립유전자 빈도는 유의한 차이가 없었고, DAT1 유전자형에 따른 음주 시작 연령, 알코올 의존증의 발병 연령 및 잠복기간에서도 차이가 없었다. 알코올 의존증의 가족력이 있는 환자군과 없는 환자군은 DAT1 유전자형의 빈도에서 차이가 있는 경향을 보였고(χ²=6.912, p=0.081), DAT1 대립유전자의 빈도에서도 유의한 차이가 있었으며(χ²=10.193, p=0.008), lambda값은 0.046였다. 결 론 : DAT1 유전자의 다형성이 알코올 의존증의 유전적 소인이 될 가능성은 적은 것으로 보이나, 알코올 의존증의 가족내 유전과는 관련있을 것으로 시사된다. Objectives : Alcoholism is known to be a heritable disease. It has been hypothesized that dopaminergic systems play an important heritable role in human behavor related to alcohol dependence, such as alcohol seeking. Therefore, genes involved in this pathway, including dopamine transporter(DAT1), which is responsible for taking released dopamine back up into presynaptic terminals and terminating dopaminergic activity, are potential candidate that may affect susceptibility to alcoholism. Analysis of a 40-base pair(bp) repeat(VNTR) in the 3' untranslated region of the DAT1 gene revealed variable number of the repeat ranging from 3 to 11 copies. Therefore, in the present study, we examined the association between alcoholism and VNTR polymorphism of DAT1. Methods : Genomic DNA analysis with polymerase chain reaction(PCR) was used to identify the presence of a VNTR polymorphism. It was carried out within a group of 94 alcoholic patients and 113 normal controls. Results : 1) There were no significant differences in allelic or genotype frequencies between the group of alcoholic patients and controls. 2) There were no significant differences in the first drinking age, onset age and latency of alcoholism according to DAT1 genotypes. 3) There was a significant difference in allelic frequencies between alcoholics with family history and those without family history. Conclusions : These results suggested that VNTR polymorphism of DAT1 is unlikely to be a factor in the genetic etiology of alcoholism, but might be related to familial transmission of alcoholism.

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.

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.

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.

4세 유아에 발생한 몰입성 하마종(plunging ranula); 증례보고

최진호,양동환,김일규,오남식 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.4

Whereas oral ranula is relatively common and presents as a cyst in the mouth, the plunging ranula is rare and manifests itself as a mass in the neck with or without an associated oral lesion. When there is a soft anterior neck swelling without oral swelling, diagnosis is still difficult. In such a case, clinical suspicion may be low and the pathologist may be misled by the histologic appearance. Recognition of the diagnosis of plunging ranula is essential for the correct treatment of these lesions We report a case of a 4-year-old girl and review the literatures to discuss the differential diagnosis and treatment modalities.

The objective of this study was to compare the shear bond strengths of five adhesive systems to the enamel and dentin of primary and permanent teeth. Fifty noncarious primary and fifty permanent teeth were collected and stored in an 0.1% thymol solution at room temperature after extraction. The tested adhesives were: Adper Scotchbond Multi-purpose Plus Adhesive (SM) Adper Single bond 2 (SB), Clearfil SE Bond (SE), Adper Prompt L-Pop (PL), G-Bond (GB). For the shear bonding test, the labial and lingual surfaces of primary and permanent teeth were used. To obtain a flat surface, the labial and lingual surfaces of the teeth were sanded on SiO₂with number 600 grit and then divided into 20 groups of 10 surfaces each. All samples were theromocycled in water 5℃ and 55℃ for 1000 cycles. The results were as follows: 1. For primary enamel, shear bond strengths of SM and SB were significantly higher than that of SE and also SM, SB, and PL were higher than GB(p<0.05). 2. For primary dentin, there were no significant differences among the shear bond strengths of any other bonding systems except differnece between SE and GB. 3. For permanent enamel, SB showed significantly higher mean shear bond strength than those of any other bonding systems(p<0.05). 4. For permanent dentin, SM showed significantly higher mean shear bond strength than that of PL and GB(p<0.05). 5.
